Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. The following description of at least one exemplary embodiment is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the problem that the food in the inner pot is easy to splash out due to the fact that the inner pot is lifted together when the pot cover is opened after the electric pressure cooker in the prior art is cooked, and further the use experience of a user on the electric pressure cooker is poor, the application provides a cooking appliance, and the cooking appliance can be an electric pressure cooker or an electric rice cooker, but is not limited to the electric pressure cooker.
As shown in fig. 1 to 10, the cooking appliance includes a pot cover 40, a pot body 10 and an inner pot 20, the pot cover 40 is openably and closably provided on the pot body 10, the inner pot 20 is provided in the pot body 10, a latch structure 30 is provided on the inner pot 20, the latch structure 30 is pivotably connected with the inner pot 20, and the latch structure 30 has a locking position in a rotation direction thereof, which is clamped with the pot body 10 to position the inner pot 20, and an unlocking position, which is separated from the pot body 10 to enable the inner pot 20 to be in a free picking and placing state.
In the application, the lock catch structure 30 is disposed on the inner pot 20, and the lock catch structure 30 is pivotally connected with the inner pot 20, wherein the lock catch structure 30 has a locking position that is clamped with the pot body 10 to position the inner pot 20 in the rotation direction thereof, and an unlocking position that is separated from the pot body 10 to enable the inner pot 20 to be in a free taking and placing state. Specifically, when the cooking utensil is in cooking operation, the lock catch structure 30 is positioned at the locking position, so that the inner pot 20 cannot be taken out of the pot body 10, and therefore, after cooking, a user can open the pot cover, the inner pot 20 cannot be lifted together due to the suction force of the sealing ring structure arranged on the pot cover 40, food in the inner pot 20 is effectively prevented from splashing out, and after the pot cover 40 is opened, when the inner pot 20 needs to be taken out of the pot body 10, the lock catch structure 30 only needs to be rotated from the locking position to the unlocking position, and the inner pot 20 can be taken out of the pot body 10 smoothly.
As shown in fig. 3 and 4, the pot body 10 is provided with a lock hole 11, the locking structure 30 includes a rotating arm 31 and a positioning boss 32, a first end of the rotating arm 31 is pivotally connected with the inner pot 20, the positioning boss 32 is disposed at a second end of the rotating arm 31, and the positioning boss 32 extends into or out of the lock hole 11 along with rotation of the rotating arm 31, so that the locking structure 30 is switched between a locking position and an unlocking position. Thus, by controlling the rotation of the rotating arm 31 relative to the inner pot 20, the positioning boss 32 rotates along with the rotating arm 31 and cooperates with the lock hole 11, when the positioning boss 32 extends into the lock hole 11, the locking structure 30 is in the locking position, the inner pot 20 cannot relatively move relative to the pot body 10, and when the positioning boss 32 exits from the lock hole 11, the locking structure 30 is in the unlocking position, and the inner pot 20 can relatively move relative to the pot body 10.
Optionally, the positioning boss 32 extending into the lock hole 11 is rotated by a preset angle, and then exits the lock hole 11, wherein the preset angle is greater than or equal to 10 degrees and less than or equal to 20 degrees. When the preset angle is too small, the locking structure 30 is easy to move from the locking position to the unlocking position due to misoperation, when the preset angle is too large, a user needs to laboriously rotate the locking structure 30 to enable the locking structure 30 to move from the locking position to the unlocking position, and a large number of experiments show that when the preset angle is greater than or equal to 10 degrees and less than or equal to 20 degrees, the locking structure 30 can be prevented from moving from the locking position to the unlocking position due to misoperation, and the user can be prevented from laboriously rotating the locking structure 30 when the user needs to enable the locking structure 30 to move from the locking position to the unlocking position.
In an alternative embodiment of the application shown in fig. 8 to 10, the wall of the aperture of the locking aperture 11 at the side facing the catch structure 30 forms an annular guiding ramp 111. In this way, the annular guiding inclined plane 111 can play a guiding role on the positioning boss 32, and the positioning boss 32 can be conveniently and laborsaving extended into the lock hole 11 or withdrawn from the lock hole 11.
As shown in fig. 2 and 3, the pan body 10 includes a housing 12 and a middle plate 13 disposed on the housing 12, and the locking hole 11 is opened on the middle plate 13. Thus, the pot body 10 is split into the shell 12 and the middle plate 13 arranged on the shell 12, so that the pot body 10 can be conveniently processed.
As shown in fig. 8, the middle plate 13 includes a middle plate body 131 and a rib structure 132, wherein the rib structure 132 is disposed on the middle plate body 131, the lock hole 11 is disposed on the rib structure 132, and the lock hole 11 extends in a lateral direction.
As shown in fig. 8, a portion of the middle plate 13 is recessed to form an avoidance groove 133, a rib structure 132 is disposed in the avoidance groove 133, the inner pot 20 includes an inner pot body 21 and a handle assembly 22 disposed on the inner pot body 21, the inner pot 20 is lapped on the middle plate 13 through the handle assembly 22, and the handle assembly 22 is disposed at a position of the avoidance groove 133. Thus, the avoidance groove 133 can position the handle assembly 22, so that relative rotation between the inner pot 20 and the pot body 10 is avoided, and dislocation between the lock hole 11 and the lock catch structure 30 is avoided.
As shown in fig. 7, in order to facilitate the user to rotate the latch structure 30, the latch structure 30 further includes an operation knob 33, and the operation knob 33 is disposed on a surface of a side of the rotating arm 31 facing away from the positioning boss 32. Thus, when the latch structure 30 is in the locked position, the user can rotate the latch structure 30 by operating the knob 33, so that the latch structure 30 is switched from the locked position to the unlocked position.
As shown in fig. 5, the inner pot 20 includes an inner pot body 21 and a handle assembly 22 provided on the inner pot body 21, and the latch structure 30 is connected to an end of the handle assembly 22 remote from the inner pot body 21. Thus, the locking structure 30 is pivotally connected with the inner pot body 21 through the handle assembly 22, so that the inner pot 20 is split into the inner pot body 21 and the handle assembly 22 arranged on the inner pot body 21, and the inner pot 20 can be conveniently processed.
As shown in fig. 5, the handle assembly 22 includes a handle bracket 221 and a handle 222, wherein the handle bracket 221 is fixedly connected with the body of the pot 10 through a first fastener 223, and the handle 222 is detachably disposed on the handle bracket 221 through a second fastener 224.
Alternatively, the first fastener 223 is a rivet and the second fastener 224 is a screw.
As shown in fig. 6 and 7, the handle 222 is provided with a mounting groove 225, two opposite mounting holes 226 are formed on the wall of the mounting groove 225, and the rotating shaft 50 passes through the latch structure 30 and is then mounted in the mounting holes 226, so that the latch structure 30 is pivotally disposed on the handle 222.
Alternatively, as shown in fig. 7, an end of the positioning boss 32 away from the rotating arm 31 is in an arc structure, so that the positioning boss 32 can conveniently and smoothly extend into the lock hole 11.
Optionally, the cooking appliance further comprises heating devices, which are all arranged in the pot body 10 and are positioned at the bottom of the inner pot to heat the inner pot.
