At present, along with the development of technology and the improvement of living standard of people, more and more cooking appliances are appeared in a kitchen so as to meet different cooking demands and preferences. These appliances not only improve cooking efficiency, but also enrich the taste and nutrition of foods.
Various cooking appliances, including electric cookers, pressure cookers, electric stewers, etc., take pressure cookers as an example, and the pressure cookers utilize steam pressure to accelerate the cooking process in a sealing manner. The pressure cooker works on the principle that the air in the cooker is sealed, so that steam cannot escape, and the pressure in the cooker is higher than the atmospheric pressure. This increased pressure increases the boiling point of the water, allowing the food to cook at higher temperatures, thereby reducing the cooking time while maintaining the nutritional ingredients and flavor of the food.
The pressure cooker used by open fire or the pressure cooker heated by electricity can realize a clear soup mode by cooking the pressure cooker in a pressure state and a thick soup mode by cooking the pressure cooker in a non-pressure state, so that the use requirements of people can be met.
In the related art, in order to conveniently switch between a pressure state and a non-pressure state, an upper cover of the pressure cooker is provided with a pressure switching structure to jack up or lower a pressure regulating valve of the pressure cooker. In order to facilitate the identification of the state switched by the pressure switching structure, the pressure cooker is also provided with a detection device, one detection part of the detection device moves along with the movement of the pressure switching structure, the other detection part of the detection device is relatively fixed on the upper cover, and the other detection part of the detection device moves in the vertical direction, and because the thickness of the upper cover is limited, the stroke between the one detection part and the other detection part is limited, and the condition of induction failure is easy to occur.
Based on this, the embodiment of the present application provides an upper cover 10 and a cooking appliance 1, aiming at improving the problem that the detecting device of the cooking appliance 1 in the related art for detecting the pressed state and the non-pressed state is easy to fail.
In the embodiment of the present application, the cooking appliance 1 may include one of a pressure cooker, an electric rice cooker and an electric stewpan, and the specific kind of the cooking appliance 1 is not limited in this embodiment. In order to facilitate the following explanation, the following embodiment of the cooking appliance 1 is a pressure cooker, and the advantages of the cooking appliance 1 according to the present application will be described in detail.
Taking a pressure cooker as an example, referring to fig. 1 and 2, the cooker body 20 generally comprises an outer cooker 21 and an inner cooker 22, wherein the inner cooker 22 is used for directly holding food, is detachably arranged in the outer cooker 21, is convenient for a user to clean and replace, can prevent the user from directly contacting the surface of the heated inner cooker 22, reduces the risk of scalding, and can be used as an insulating layer to reduce heat loss, so that the food in the inner cooker 22 can be heated more quickly and uniformly.
Referring to fig. 1 to 5, an upper cover 10 is openably and closably disposed on a pan body 20 and cooperates with the pan body 20 to form a cooking cavity 130. The upper cover 10 includes a cover body 100, a pressure regulating valve 200, a pressure switching structure 300, and a sensing assembly 400. Wherein, the cover 100 is provided with a pressure relief port 140 communicating with the cooking cavity 130. The pressure regulating valve 200 is movably installed to the cover 100 to open or close the pressure relief port 140. In case of pressure cooking, the pressure regulating valve 200 blocks the pressure relief port 140, steam in the cooking cavity 130 cannot be freely released, and boiling point of water is increased, thereby improving cooking temperature and pressure and accelerating cooking process of food materials. It will be appreciated that once the pressure within the cooking chamber 130 exceeds the safe range, the pressure regulating valve 200 will be lifted by the steam pressure as a secondary line of defense, forcibly releasing the pressure to avoid accidents. In case of non-pressure cooking, the pressure regulating valve 200 is at least partially separated from the pressure relief port 140, so that the pressure relief port 140 can communicate the outside with the cooking cavity 130, thereby balancing the air pressure of the cooking cavity 130 with the outside.
It is understood that the cover 100 may be provided with an exhaust pipe, the exhaust pipe forms the pressure relief port 140 communicating with the cooking cavity 130, and the pressure regulating valve 200 is sleeved on the exhaust pipe. In this way, the pressure regulating valve 200 can be stably fixed to the pressure relief port 140, so that the cooking chamber 130 forms a stable pressurized state.
Referring to fig. 4 and 5, the pressure switching structure 300 includes a driving member 310 and a lever 320, wherein the driving member 310 is movably connected with the cover 100 and is in transmission connection with one end of the lever 320. The lever 320 is rotatably connected with the cover 100, and an end of the lever 320 away from the driving member 310 abuts against the pressure regulating valve 200. Specifically, in case that the cooking cavity 130 needs to be switched to be pressurized or non-pressurized, the user drives the driving member 310 to move relative to the cover 100, and the driving member 310 simultaneously drives one end of the lever 320 to be pressed down during the movement, so that the other end of the lever 320 is lifted up, thereby enabling the lever 320 to jack up the pressure regulating valve 200, and at this time, the pressure regulating valve 200 can leave the pressure relief port 140, so that the cooking cavity 130 can be switched from the pressurized state to the non-pressurized state. When the driving member 310 is driven again to move, the driving member 310 can release the state of pushing down the lever 320, and the other end of the lever 320 is lowered under the gravity of the pressure regulating valve 200 or the self gravity of the pressure regulating valve 200, and the pressure regulating valve 200 can block the pressure relief opening 140, so that the cooking cavity 130 is switched from the non-pressure state to the pressure state. The pressure switching structure 300 of the embodiment of the application can facilitate the pressure cooker to switch between the pressure state and the non-pressure state during cooking, and is convenient for users to perform different cooking modes.
Referring to fig. 2, the detecting assembly 400 includes a first detecting member 410, a push rod 420, and a second detecting member 430. The push rod 420 is rotatably connected with the cover 100 and is in transmission connection with the driving member 310, the first detecting member 410 is mounted at one end of the push rod 420 far away from the driving member 310, and the second detecting member 430 is mounted on the cover 100 or the pot 20. Specifically, when the user drives the driving member 310 to move relative to the cover 100 and the driving member 310 drives one end of the lever 320 to press down, the driving member 310 can drive the push rod 420 to swing relative to the cover 100, and at this time, the first detecting member 410 mounted on the other end of the push rod 420 can approach or separate from the second detecting member 430 mounted on the cover 100, so that it can be identified that the cooking cavity 130 is switched from the pressed state to the non-pressed state. When the driving member 310 is driven again to move, the driving member 310 can release the state of pushing the lever 320, the driving member 310 drives the push rod 420 to rotate relative to the cover 100, and at this time, the first detecting member 410 mounted at the other end of the push rod 420 can be far away from or close to the second detecting member 430 mounted on the cover 100, so that the cooking cavity 130 can be identified to be switched from the non-pressure state to the pressure state.
For the embodiment in which the second detecting member 430 is mounted on the pot body 20, the detecting assembly 400 can detect the signal only when the upper cover 10 is fastened to the pot body 20, so that the using effect of the product is improved.
It should be noted that, the detection assembly 400 may include any one of a photoelectric switch, a reed switch proximity switch, and a hall proximity switch, where the photoelectric switch can utilize shielding or reflection of a light beam by a detected object, and a synchronization loop turns on a circuit, so as to detect whether the object exists, and the reed switch proximity switch and the hall proximity switch may be used as a position sensor. Here, the above-described detecting unit 400 is not particularly limited. The detection assembly 400 includes a reed switch as described further below.
Specifically, the first detecting member 410 may be one of a reed pipe and a magnet, and the second detecting member 430 may be the other of the reed pipe and the magnet. Illustratively, the first detecting member 410 is a magnet, the second detecting member 430 is a reed switch, the magnet and the reed switch are close to/remote from each other, and the reed switch sends out corresponding on/off signals.
According to the upper cover 10 of the embodiment of the present application, in the process that the driving member 310 is forced to move relative to the cover 100, the driving member 310 can drive the lever 320 and the push rod 420 to rotate relative to the cover 100 together, so as to jack up the pressure regulating valve 200 and drive the first detecting member 410 to move along the circumferential direction of the cover 100 to approach or separate from the second detecting member 430, respectively. In the process that the driving member 310 drives the lever 320 to press down, the pressure regulating valve 200 is lifted up, and the driving member 310 drives the first detecting member 410 on the push rod 420 to be away from the second detecting member 430, so that the cooking cavity 130 can be identified to be switched to the non-pressure state. The driving member 310 moves away from the lever 320, so that the acting force on the lever 320 is relieved, the pressure regulating valve 200 seals the pressure relief opening 120 under the action of gravity, and at this time, the driving member 310 drives the first detecting member 410 on the push rod 420 to approach the second detecting member 430, so that the cooking cavity 130 can be identified to switch to the pressed state.
It should be noted that, the push rod 420 and the cover 100 are rotationally connected by a rotation shaft, and the axial direction of the transmission shaft extends in the vertical direction, and when the driving member 310 applies a force to one end of the push rod 420, the push rod 420 swings in the circumferential direction of the cover 100. It will be appreciated that the cover 100 has a larger stroke in the circumferential direction, and the present application can prevent the detection assembly 400 from detecting failure by designing the push rod 420 to swing in the circumferential direction of the cover 100, thereby increasing the stroke between the first detecting member 410 and the second detecting member 430.
In some embodiments, referring to fig. 9 in combination, the lid 100 includes an inner lid assembly 110 and a face lid 120. The cover 120 is covered outside the inner cover assembly 110 and encloses the inner cover 111 and the cover 112 to form an installation space 160, and the cover 120 is provided with a first avoiding hole corresponding to the pressure relief opening 140. The lever 320 is mounted in the mounting space 160, and the driving member 310 is slidably mounted on the top surface of the cover 120 and at least partially positioned in the mounting space 160 to abut against the lever 320. Thus, the lever 320 can be installed in a hidden manner, the whole structure looks more neat and beautiful, and a user can not directly contact the lever 320 when using the device, so that the possibility of misoperation is reduced.
Further, referring to fig. 6, 7 and 9, the inner cap assembly 110 includes an inner cap 111 and a cap 112, and the cap 112 is fixed to the inner cap 111 and provided with a pressure relief vent 140. The inner lid 111 is fixedly coupled to the lid 120 such that the inner lid 111, the pot lid 112, and the lid 120 together define an installation space 160. The pot cover 112 and the inner cover 111, and the inner cover 111 and the surface cover 120 may be relatively fixed by a fastening, screwing, or other connection method. Wherein the lever 320 is rotatably coupled to the cover 120. Specifically, referring to fig. 13 in combination, a fixing groove is formed on an inner wall surface of the cover 120, a cantilever 321 is formed in a middle portion of the lever 320, and the cantilever 321 is inserted into the fixing groove, so that opposite sides of the lever 320 can swing around the cantilever 321.
In some embodiments, referring again to fig. 6, 7 and 9, the push rod 420 is rotatably connected to the inner cover 111, and the inner cover 111 is provided with a recess 1111. During the relative rotation of the push rod 420 and the inner cap 111, the push rod 420 and the first detecting member 410 are swingably disposed in the escape groove 1111. In this way, the utilization of the internal space of the upper cover 10 can be optimized, making the whole structure more compact, reducing unnecessary volume and weight. Furthermore, since the push rod 420 and the first detecting member 410 are rotatably disposed in the escape groove 1111, they can be freely moved without interfering with other components.
Referring to fig. 9, the top surface of the cover 120 is provided with a mounting groove 121, and the mounting groove 121 is upwardly open and is used to accommodate at least a portion of the pressure regulating valve 200. The cover 120 is provided with a avoiding opening which is communicated with the installation space 160 and the installation groove 121, and one end of the lever 320, which is far away from the driving piece 310, is penetrated through the avoiding opening and extends into the bottom of the pressure regulating valve 200. The upper cover 10 further comprises a sealing member 600, wherein the sealing member 600 is sleeved at one end of the lever 320 far away from the driving member 310, and the sealing member 600 always seals the avoiding opening during the movement of the lever 320. So set up, sealing member 600 can airtight installation space 160, specifically, when pressure regulating valve 200 is lifted, the blast pipe can discharge a large amount of steam, and sealing member 600 seals all the time and dodges the mouth, then can prevent that steam from flowing back to installation space 160 in, and then can prevent impurity such as dust, moisture from dodging mouthful entering installation space 160 in, when having improved spare part life, ensured the safe operation of equipment.
In order to facilitate the openable cover of the upper cover 10 to be provided on the pot 20, the upper cover 10 of the embodiment of the present application further includes a handle assembly 500, and a user can grasp the handle assembly 500 to remove the upper cover 10 from the pot 20 when the upper cover 10 needs to be opened.
Further, referring to fig. 10, the handle assembly 500 includes a handle 510, a driving rod 520, and a reset member 530. The handle 510 is mounted to the face cover 120, wherein the handle 510 and the face cover 120 may be one or more of a snap-fit connection, a screw connection. The driving rod 520 penetrates the handle 510 and the face cover 120, and is slidably disposed in a vertical direction with respect to the handle 510. The reset member 530 has one end connected to the handle 510 and the other end connected to the driving rod 520 to drive the driving rod 520 to have an upward force. The return 530 may be in the form of a spring, tension spring, or the like.
Specifically, when the user presses the top of the driving lever 520, the bottom of the driving lever 520 presses down one end of the lever 320 away from the pressure regulating valve 200, so that the other end of the lever 320 lifts up the pressure regulating valve 200. So set up, the user can realize the mode that cooking utensil 1 spouts the pressure release through handle subassembly 500, still can realize the mode that cooking utensil 1 continuously releases the pressure through pressure switching structure 300. During cooking, if the internal pressure of the cooking appliance 1 is too high, safety hazards may be raised. Through the point spraying pressure release mode, a user can gradually release the excessive pressure, and scalding or equipment damage caused by suddenly releasing a large amount of steam or gas is avoided. The continuous pressure release mode allows the user to continuously and stably reduce the pressure in the cooking cavity 130 according to the cooking needs, thereby ensuring the safety of the cooking process.
In addition, different food materials and cooking methods require different cooking pressures. By the spot spray pressure relief mode, a user can precisely control the pressure variation in the cooking cavity 130, thereby optimizing the cooking effect. For example, when stewing meat, the meat can be made more tender and juicy by gradually releasing the pressure. The continuous pressure release mode is suitable for cooking processes requiring a lower pressure to be maintained for a long time, such as porridge cooking or soup stewing.
For the upper cover 10 described above and below, the detection assembly 400 and the pressure regulating valve 200 are disposed far away from each other along the radial direction of the cover body 100, so that the lever 320 has a longer arm, which can effectively improve the height of the lever 320 to jack up the pressure regulating valve 200, thereby ensuring the stability of pressure regulation.
The driving member 310 is movably connected to the cover 100, and can drive the lever 320 and the push rod 420 to rotate in various ways, which will be described in detail below.
The driving member 310 includes a main body 311 and a pressing portion 312, wherein the main body 311 is slidably connected to the cover 100, and the pressing portion 312 has a pressing surface 312a slidably engaged with the lever 320. The sliding direction of the pressing portion 312 may be the same as the extending direction of the lever 320, or may intersect the extending direction of the lever 320. In order to improve the sliding stability of the driving member 310 on the cover 100, the cover 100 is provided with a sliding slot 150, and the main body 311 is slidably mounted on the sliding slot 150.
In the solution where the sliding direction of the pressing portion 312 intersects with the extending direction of the lever 320, referring to fig. 8 to 13, the driving member 310 moves to align with the lever 320 at the side of the lever 320, and when the driving member 310 is located above the lever 320, the pressing surface 312a of the pressing portion 312 abuts against the lever 320. The pressing surface 312a includes a guide section 3121 and a pressing section 3122 connected, the guide section 3121 is connected to a side of the pressing section 3122 close to the lever 320, the guide section 3121 is disposed obliquely from bottom to top in a direction away from the pressing section 3122, and the pressing section 3122 extends in a horizontal direction.
Specifically, during the movement of the driving member 310 toward the lever 320, the guide section 3121 may guide the surface of the lever 320 along the guide section 3121 to be pressed down, and when the lever 320 is positioned at the pressing section 3122, the pressing section 3122 may firmly abut against the lever 320, so that the cooking appliance 1 may continuously and smoothly decompress.
In this embodiment, the main body 311 may be disposed annularly or arcuately, and the shape of the chute 150 is adapted to the shape of the main body 311. In the annular form of the body portion 311, the cover 120 is provided with an annular chute 150, and the body portion 311 can exert a pressing force on the lever 320 and release the pressing force on the lever 320 in the chute 150. Further, the bottom of the main body 311 is provided with a rotating shaft, the rotating shaft comprises a shaft body and a limiting part, the shaft body penetrates through the surface cover 120, the limiting part is abutted against the bottom surface of the surface cover 120, and the main body 311 is abutted against the top surface of the surface cover 120, so that the main body 311 can be fixed on the surface cover 120 and can rotate relative to the surface cover 120.
Of course, in order to improve the stability of the rotation of the main body 311 with respect to the cover 120, the bottom of the main body 311 has a plurality of rotation shafts, and the rotation shafts are disposed at intervals at the bottom of the main body 311.
Further, the chute 150 is disposed around the center of the cover 100. It will be appreciated that, in general, the handle assembly 500 will be mounted in the center of the cover 100, and the chute 150 of the present application may be disposed around the handle assembly 500, thereby allowing for a reasonable use of the space on the top surface of the face cover 120.
In the solution in which the sliding direction of the driving member 310 is the same as the extending direction of the lever 320, referring to fig. 1 to 3, the main body 311 and the pressing portion 312 may be disposed in a strip shape, and the sliding groove 150 is also disposed in a strip shape and extends toward the outside in a direction away from the center of the cover 100. That is, the body portion 311 moves in the extending direction of the lever 320, so that the angle at which the lever 320 swings with respect to the face cover 120 is changed by the abutment surface 312a abutting against the junction of the lever 320 and the face cover 120 at a position relatively close to or relatively far from the junction of the lever 320, and thus one end of the lever 320 can be depressed, so that the other end of the lever 320 can raise the pressure regulating valve 200.
The main body 311 and the pressing portion 312 in the above two embodiments may be integrally formed, and may be integrally formed by injection molding, so that the processing efficiency is high.
In order to improve the stability of the contact between the driver 310 and the lever 320, a pressing portion 322 is formed at an end of the lever 320 remote from the pressure regulating valve 200, which is tilted upward, and the pressing portion 312 contacts the pressing portion 322. In some embodiments, the abutment 322 extends upwardly in a direction toward the pressure regulating valve 200. Of course, the pressing portion 322 may also extend upward in a direction away from the pressure regulating valve 200. In embodiments where the driver 310 would move laterally of the lever 320 into alignment with the lever 320, the tilt orientation of the guide section 3121 may be further accommodated.
It should be noted that, referring to fig. 1 to 5 in combination, in the case where the main body 311 is configured in a strip shape, the cover body 100 may include a mounting seat 170, and the mounting seat 170 is mounted on the top of the cover 120 and defines the sliding slot 150 together with the cover 120, and the main body 311 slides in the sliding slot 150. In this way, the mounting of the driving member 310 can be facilitated, and the sliding of the driving member 310 can be facilitated by the user.
One of the body portion 311 and the push rod 420 is provided with a driving shaft 3111, and the other is provided with a driving groove 421, and the driving shaft 3111 is movably inserted into the driving groove 421. Referring to fig. 11 and 12, for example, the main body 311 is provided with a driving shaft 3111, the push rod 420 is provided with a driving slot 421, and the driving shaft 3111 moves in the driving slot 421 during the process of moving the driving member 310 and driving the push rod 420 to swing. Thus, in the process that the main body 311 pushes the push rod 420 to move, the driving shaft 3111 can have a certain swinging space in the driving shaft 3111, so that the push rod 420 can adapt to a complex working environment and a moving track, and the first detecting member 410 can swing along the circumferential direction of the cover body 100. Moreover, the driving groove 421 can avoid the jamming phenomenon caused by improper force direction during the swinging process of the main body 311 and the push rod 420.
In order to facilitate sliding of the main body 311, referring to fig. 1 to 5 and 8, the driving member 310 according to the embodiment of the present application further includes a knob 313, and the knob 313 is connected to the main body 311 and exposed outside the cover 100. In this way, the body 311, the lever 320, and other components can be mounted in a hidden manner, and the body 311 can be driven to slide relative to the cover 100 by simply pulling the knob 313. It will be appreciated that in order to increase the friction between the user's finger and the knob 313, a protrusion or a frosted portion may be provided on the outer surface of the knob 313. The knob 313 and the main body 311 may be integrally formed or may be separately provided, and then may be integrally mounted by one or more of fastening, screwing, bonding, and the like.
In other embodiments, the driving member 310 may further move in the vertical direction of the cover 100, so that the driving member 310 can also press one end of the lever 320, thereby driving the other end of the lever 320 to jack up the pressure regulating valve 200. In this embodiment, a wedge surface may be provided at the bottom of the driving member 310, and a wedge surface may be provided at an end of the push rod 420 remote from the first detecting member 410, where the wedge surface of the driving member 310 is engaged with the wedge surface of the push rod 420. When the driving member 310 moves vertically, the push rod 420 can be driven to rotate in the circumferential direction of the cover 100 about a rotation shaft arranged vertically in the axial direction by the wedge surface. Here, the specific movement mode of the driving member 310 is not limited, and it is within the scope of the present application as long as the push rod 420 can be driven to rotate in the circumferential direction of the cover 100.
