Description

Integrated pressure cooker convenient to open cover

Technical Field

The invention relates to the field of kitchen cooking appliances, in particular to a one-piece pressure cooker with a cover convenient to open.

Background

The pressure cooker cooks food under high temperature and high pressure, so the food can be quickly cooked. In order to form a high pressure environment in the cooking cavity, a pressure-bearing structure is generally disposed on the lid. But the arrangement of the pressure bearing structure can cause the trouble of uncovering.

In the prior art, the following two types of pressure-bearing mechanisms are mainly used.

The first pressure-bearing structure is that a rotating lock cover is arranged on a pot cover, cover teeth are arranged on the lock cover, pot teeth are arranged on a corresponding pot body, and after the pot cover is buckled on the pot body, the lock cover is driven to rotate through a rotating handle (or a motor) on the pot cover, so that the cover teeth are meshed with the pot teeth, and then pressure cooking is carried out. After cooking is finished, the locking cover is driven to rotate through the rotating handle, so that the cover teeth and the pot teeth are staggered, and the pot cover can be separated from the pot body. The pressure-bearing mode can be applied to a split pressure cooker or a conjoined pressure cooker. The split pressure cooker has the advantages that the cover teeth are staggered with the cooker teeth, the cover can be taken away and completely separated from the cooker body, and the cover is completely separated from the cooker body, so that the cover is free of an electric display structure and is generally applied to low-end machines. The disjunctor formula pressure cooker is that after the lid tooth staggers with the pot tooth, through the anterior buckle button of operation pot cover for the articulated shaft rotation at pot cover rear portion relatively opens the pot cover, and the anterior and the pot body components of a whole that can function independently of pot cover, rear portion still connect on the pot body, can make the electric display structure on its pot cover, generally uses at high-end machine. The pressure is applied through the rotating lock cover, the unlocking operation is troublesome, a user needs to rotate the rotating handle, the lock cover needs to be meshed with and staggered with the pot teeth of the pot body, the rotating friction force is large, and the problems that the locking is not in place, the safety is affected and the like can occur. Especially for the integrated pressure cooker, the cover opening process is complex, after pressure cooking is finished, the rotating handle needs to be rotated firstly to unlock the cooker cover and the cooker body, and then the buckle button is operated to separate the buckle between the cooker cover and the cooker body.

The second pressure-bearing structure is that openable clamps are arranged on the cooker cover and arranged on the periphery of the metal inner cover, when the clamps are closed, the inner cover and the edge of the inner container are clamped by the clamps, and when the clamps are opened, the clamps are positioned outside the edge of the inner container, so that the cooker cover can be separated from the cooker body. The clamp is opened and closed generally by arranging two buttons at the top of the pot cover, the clamp is opened by one unlocking button, the pot cover can be separated from the pot body, the clamp is closed by the other locking button, and the pot cover is locked with the pot body, so that pressure cooking can be carried out. The opening and closing of the clamp is realized by arranging a rotary handle. Because the clamp needs to be opened and closed, and different from a rotating locking cover, the clamp needs to have a space in the radius direction of the circumference, the clamp in the prior art is generally exposed, and therefore, the clamp type pressure cooker is mainly applied to a split type pressure cooker.

When the fastener of the front part of thepot cover 2 is separated, thepot cover 2 can be bounced open by the elasticity of the torsion spring, so that the front part of thepot cover 2 is separated from thepot body 1. The inner liner 22 is a plastic part, themovable clamping piece 21 is fixed at the front end of the inner liner 22, and the front part of the inner liner 22 is provided with a through hole, so that themovable clamping piece 21 can pass through the through hole and extend to the lower surface of the inner liner 22 to be matched with thefastener 11 on thepot body 1. Theinner cover 23 is positioned below the inner liner 22, theinner cover 23 can be fixed on the inner liner 22 in a floating mode, theinner cover 23 is a metal piece, and theinner cover 23 is matched with theinner container 12 on thepot body 1 to form a pressure cooking cavity. Theclamp 24 is located on the periphery of theinner cover 23, theclamp 24 is a metal part, theclamp 24 can be opened and closed, when theclamp 24 is closed, the edge of theinner cover 23 and the edge of theinner container 12 are located between the upper surface and the lower surface of theclamp 24, when the cooking cavity is pressed upwards in pressure cooking, theinner cover 23 has a tendency of floating upwards, and theclamp 24 clamps theinner cover 23 and the edge of theinner container 12, so that theinner cover 23 can be prevented from floating upwards, and theinner cover 23 and theinner container 12 can form the pressure cooking cavity. When the cooking is finished and the cover needs to be opened, theclamp 24 is opened, so that the edge of theinner container 12 is staggered with theclamp 24, theinner cover 23 can be separated from theinner container 12, and thepot cover 2 can be opened to separate the pot body. Certainly, thecooker body 1 can also comprise an outer cooker, and theclamp 24 is meshed with and staggered with the edge of the outer cooker to lock and unlock the cooker cover and the cooker body.

According to the invention, the unlockingbutton 4 is arranged, so that the unlockingbutton 4 and the buckle button in the prior art are combined into a whole, the space of the pressure cooker is saved, the operation of a user is facilitated, the unlocking and the unlocking can be realized by operating one unlockingbutton 4 by the user, and thecooker cover 1 is opened. When the unlockingbutton 4 is moved to the first position, the clamp is opened, the pot cover is not opened, and the operations such as exhausting and the like can be performed, so that the situation that the pot cover is directly opened and a user is scalded due to the fact that a certain amount of residual pressure exists in the pot body is avoided. Then the unlocking button is continuously touched, so that the movable clamping piece is separated from the fastener, and the pot cover is opened. Moreover, the clamp is opened firstly, the clamping piece is separated, the use by a user is facilitated, the condition that the unlocking button is not smooth is avoided, and the clamp can be prevented from colliding with the liner. Because if earlier with the separation of buckle spare, generally all be equipped with the torsional spring on the pot cover, the pot cover can upwards bounce off the trend of separating the pot body, if clamp still does not open this moment, clamp can collide with the contact of inner bag border, receive blockking at inner bag border just can not enough break away from the pot body in addition, when continuing to operate the drive clamp of release button and opening, can have very big frictional resistance between clamp and the inner bag border, cause the release button to press motionlessly, influence the user and use.

In this embodiment, the outside of the unlockingbutton 4 is a force-bearing surface, and the inside thereof is provided with a first touchingpart 41 and a secondtouching part 42, the first touchingpart 41 acts on theclamp 24, and the second touchingpart 42 acts on themovable clamp 21. In a specific operation, when the unlockingbutton 4 is touched and the unlockingbutton 4 moves from the initial position (as shown in fig. 3) to the first position, the first touchingpart 41 acts on theclamp 24 from the closed position to the open position, and at this stage, the second touchingpart 42 does not act on themovable clamping piece 21; when the unlockingbutton 4 is further activated, the second activatingpart 42 acts on themovable catch 21 to move themovable catch 21 from the engaging position with thecatch 11 to the disengaging position with thecatch 11 when the unlockingbutton 4 is moved from the first position to the second position (as shown in fig. 4), and thereafter thelid 2 can be disengaged and opened with respect to thepot body 1. Of course, in other embodiments, the first position and the second position may coincide, that is, when the unlocking button is triggered, the clamp is opened and the movable clip is separated, and the completely opened position of the clamp and the separated position of the movable clip are the same position.

In the present embodiment, referring to fig. 2-4, afirst transmission mechanism 3 is provided between the unlockingbutton 4 and theclamp 24, and the unlockingbutton 4 realizes the opening of theclamp 24 through thefirst transmission mechanism 3. Thefirst transmission mechanism 3 includes afirst button driver 31 connected to theunlock button 4, aclamp link 32 connected to theclamp 24, and apivoting mechanism 33 located between thefirst button driver 31 and theclamp link 32.

Referring to fig. 5, the transfer mechanism of this embodiment includes a transmission gear, and the first button transmission part triggers the transmission gear to rotate, and the transmission gear drives the clamp connection part to move. The driving force of the unlocking button is converted to the opening force of the clamp through the transmission gear, the transmission gear mainly has the function of converting the direction of the force, the direction of the force required by the opening of the clamp is different from the direction of the driving force of the unlocking button, the direction of the force can be converted through the transmission gear, and the number of the transmission gear can be one or more. In this embodiment, referring to fig. 5, the transfer mechanism of this embodiment further includes a force-bearingplate 331, the number of the transmission gears of this embodiment is multiple, thefirst transmission gear 332 is linked with the force-bearingplate 331, that is, the first transmission gear is provided with a square hole, so that the force-bearingplate 331 passes through the first transmission gear, and when the force-bearingplate 331 swings, thefirst transmission gear 332 can be driven to rotate. Thefirst transmission gear 332 is also linked with asecond transmission gear 333, and thesecond transmission gear 333 is linked with theclamp connecting piece 32 on one side. Athird drive gear 334 is also provided between the two jaw connectors so that when one of thejaw connectors 32 is opened, theother jaw connector 32 is also opened. The working principle is as follows: when the unlocking button moves to act on the clamp, thefirst touch part 41 acts on the firstbutton transmission part 31, the firstbutton transmission part 31 acts on one side of thestress plate 331, so that thestress plate 331 swings, thestress plate 331 swings to drive thefirst transmission gear 332 to rotate, and further drives thesecond transmission gear 333 to rotate, so that theclamp connecting piece 32 on one side is driven to open, theclamp connecting piece 32 drives the middlethird transmission gear 334 to rotate, thethird transmission gear 334 drives theclamp connecting piece 32 on the other side to open, so that theclamp 24 opens, and thepot cover 2 can be separated from thepot body 1. The open position of theclamp 24 is the first position, but themovable catch 21 is still engaged with thecatch 11. Then, when the unlockingbutton 4 is further touched, the second touchingpart 42 acts on themovable catch 21, so that themovable catch 21 is separated from thecatch 11, and at this time, the front part of thepot cover 2 can be separated from thepot body 1, so that thepot cover 2 is opened. It will be appreciated that thesecond trigger 42 is spaced from themovable catch 21 such that when therelease button 4 is moved from the initial position to the first position, only thefirst trigger 41 acts as a clamp, and thesecond trigger 42 does not trigger themovable catch 21, or only a portion of themovable catch 21 is triggered without separating it from thecatch 11. Thereby realize opening earlier clamp, again with the separation of buckle spare, convenience of customers uses, avoids appearing the condition that the unblock button is not smooth and easy, can also avoid clamp and inner bag to collide with.

In addition, in this embodiment, as shown in fig. 6, a firstelastic device 311 is disposed on the firstbutton driving member 31, when the unlockingbutton 4 moves from the initial position to the first position, the first elastic device does not deform, and when the unlockingbutton 4 continues to be triggered to move to the second position, the first elastic device deforms. The firstelastic device 311 of the present embodiment is a spring, the firstbutton transmission member 31 includes a transmission rod 312 and a fixing sleeve 313 sleeved outside the transmission rod 312, the fixing sleeve 313 is fixed on the lining 22, so that the transmission rod 312 moves in the fixing sleeve 313, and the spring is sleeved between the two, so that the spring deforms when the transmission rod 312 moves. In this embodiment, when the unlock button moves from the initial position to the first position, the spring is not deformed, i.e., no force is applied to the spring or the two are not yet in contact when the button moves from the initial position to the first position. Therefore, when the unlocking button moves to the first position from the initial position, the clamp is opened, when the unlocking button is released, the unlocking button cannot reset, and the unlocking button is lower than the initial position. At the moment, the clamp is opened, but the pot cover is not separated from the pot body, if a user starts heating by misoperation, the pot cover can be opened due to pressure rise, so that the unlocking button at the moment is lower than the initial position, the user can conveniently recognize the unlocking button, and the clamp is not closed at the moment and can not perform pressure cooking. Of course, in order to further ensure the use safety, a locking detection device can be added, and when the clamp is closed and the pot cover is locked with the pot body, the pressure cooking can be carried out.

In this embodiment, the lid is further provided with alocking button 5, and thelocking button 5 is triggered to move, so that theclamp 24 is closed. Referring to fig. 2-4, a second transmission mechanism is arranged between thelocking button 5 and theclamp 24, and thelocking button 5 realizes the closing of theclamp 24 through the second transmission mechanism. The outer side of thelocking button 5 is a stress surface, the inner side is provided with atouch part 51, and thetouch part 51 acts on a second transmission mechanism to further realize the closing of theclamp 24.

Referring to fig. 2-4, the second actuator includes asecond button driver 52 coupled to thelock button 5, aclamp link 32 coupled to theclamp 24, and apivoting mechanism 33 positioned between thesecond button driver 52 and theclamp link 32. That is, theintermediate rotation mechanism 33 is shared by thefirst transmission mechanism 3 and the second transmission mechanism, so that the structure can be simplified and the cost can be reduced. The operation of therelay mechanism 33 is similar to the unlocking process described above, but the process is reversed. The specific process is as follows: when the pot cover is covered, thelocking button 5 is touched, thetouch part 51 of thelocking button 5 acts on the secondbutton transmission piece 52, and the secondbutton transmission piece 52 acts on the other side of thestress plate 331, so that thestress plate 331 swings (the direction is just opposite to the unlocking swinging direction), and the subsequent transmission gears rotate in opposite directions, and finally theclamp 24 is driven to close. In this embodiment, in order to improve the opening and closing hand feeling, the transfer mechanism further includes aspring 335, one end of thespring 335 is fixed on the force-bearingplate 331, and the other end is fixed on the liner 22, so that when unlocking or locking, thespring 335 has the function of assisting the force-bearingplate 331 to swing, and the hand feeling when touching the button can be improved.

In this embodiment, a secondelastic device 521 is disposed on the second transmission mechanism, when thelocking button 5 is triggered to drive the clamp to close, the secondelastic device 521 deforms, and when thelocking button 5 is released, the secondelastic device 521 recovers to deform to drive thelocking button 5 to return. The second elastic means are similar in structure to the first elastic means, as can be seen in fig. 6. However, the deformation position is driven by the first elastic means, and the secondelastic means 521 is deformed when thelocking button 5 moves, that is, the first elastic means is deformed when contacting the unlocking button at the first position, and the second elastic means is deformed when contacting thelocking button 5 at the initial position. Therefore, when thelocking button 5 is released, the second elastic means 521 can restore the deformation to drive thelocking button 5 to return to the original position.

In the present embodiment, thelocking button 5 is flush with the unlockingbutton 4 in the initial state. Preferably, the two are arranged adjacently, so that part of the transmission mechanism between the button and the clamp can be shared, and the cost is saved. Namely, the unlocking button and the locking button of the embodiment are arranged separately. It can be understood that the unlocking button is provided with an unlocking mark, and the locking button is provided with a locking mark. The unlocking mark and the locking mark can be characters or patterns. The unlockingbutton 4 is located on the front side of thelid 2. Therefore, the unlocking button and the locking button are arranged adjacently, so that the product is compact and reasonable in layout. The front and back directions of the invention are based on the state of the machine in normal use, and the hinge joint is far away from the user, namely the back side, and the unlocking button is near the user, namely the front side in normal use.

The pressure cooker of the embodiment is used according to the following principle: when the pressure cooking is finished and the cover needs to be opened, the pressure is firstly reduced to the cover opening pressure through the air exhausting operation, such as air exhausting through an air exhausting button or air exhausting through a solenoid valve. After the pressure is reduced to the pressure capable of opening the cover, the unlockingbutton 4 is triggered to move, when the unlockingbutton 4 moves from the initial position to the first position, thefirst trigger part 41 on the inner side of the unlockingbutton 4 drives thefirst transmission mechanism 3, so that theclamp 24 is opened, namely theclamp 24 is staggered with the edge of theinner container 12 on thepot body 1. At the moment, thepot cover 2 and thepot body 1 are unlocked, and the unlockingbutton 4 is lower than the initial position, so that a user can recognize that the pot cover is in an unlocking state at the moment and cannot perform heating cooking. In order to avoid the situation that the residual pressure in the cooker burns consumers when the cooker cover is opened, the exhaust operation can be further carried out, or the exhaust can be driven in the opening process of the clamp so that the exhaust pipe is in an open state at the moment. Then, when the unlockingbutton 4 is further activated to move to the second position, themovable catch 21 is separated from thecatch 11, and in the process, the firstelastic means 311 is deformed. Thelid 2 can thus be rotated open relative to thebody 1. It can be seen that with the structure of the embodiment, the pressure cooker is unlocked and unlocked through one operation of touching the unlockingbutton 4, and the pressure cooker is opened. After thecooker cover 2 is opened, when the cooker cover needs to be closed again for cooking, firstly, thecooker cover 2 is buckled on thecooker body 1, and themovable clamping piece 21 is meshed with thefastener 11. Thelocking button 5 is then activated, and thelocking button 5 causes thejaws 24 to move from the open position to the closed position via the second actuator, after which pressure cooking can take place.

Example two
