As shown in fig. 1,2, 4 and 5, in the present embodiment, the first fitting structure 251 is a first concave structure that fits with the first convex structure 112. When the first workpiece moves along the left-right direction of the pot body 10, the inner wall of the first concave structure on the first workpiece will abut against the first convex structure 112 to limit the first concave structure. The first concave structure is arranged on the first workpiece, so that the first workpiece is limited. In addition, the convex structure and the concave structure are matched simply and are easy to process.

As shown in fig. 1 and 5, in the present embodiment, the groove wall of the accommodating groove 111 includes a groove top wall 1111, a groove bottom wall 1112, and a connecting side wall 1113 connecting the groove top wall 1111 and the groove bottom wall 1112, which are disposed opposite to each other, and the first projection structure 112 is disposed on the groove bottom wall 1112. The structure is simple and easy to process. Of course, it will be appreciated by those skilled in the art that the first projection arrangement 112 may also be provided on the attachment sidewall 1113 depending on the actual situation (actual placement of the second workpiece).

As shown in fig. 1 and 5, in the present embodiment, the first protrusion structure 112 is located at the connection between the groove bottom wall 1112 and the connection sidewall 1113. When the user takes the water tank, the first workpiece can be taken down by directly applying forward force to the first workpiece. Therefore, the structure is convenient for a user to take the first workpiece, so that the use experience of the user is improved. Of course, it should be understood by those skilled in the art that the location of the first protrusion structure 112 is not limited to the connection between the groove bottom wall 1112 and the connecting sidewall 1113, but may be located in the middle of the groove bottom wall 1112. When the first protruding structure 112 is disposed in the middle of the groove bottom wall 1112, the first recessed structure on the first work corresponds to a mounting hole, and when the first work is mounted in the accommodating groove 111, the first protruding structure 112 protrudes into the mounting hole. When the user takes the first workpiece, the first workpiece is required to be moved upwards, so that the first protruding structure 112 is separated from the mounting hole.

In the above structure, the cooling cavity 1 can quickly reduce the temperature of the inner pot 12, so that the pressure in the inner pot 12 is also quickly reduced, thereby realizing quick uncovering and improving user experience. Since the first work is a part that requires the user to take it from time to time, the accommodating groove 111 accommodating it is provided on the outer side wall of the housing, thereby facilitating the user's taking.

Since the cooling liquid in the cooling chamber 4 is brought into contact with the inner pan 12 having a relatively high temperature, the temperature of the cooling liquid is rapidly increased. The heat absorbing capacity of the cooling liquid will be reduced and the heat absorbing efficiency will be lower due to the higher temperature of the cooling liquid. In order to be able to further increase the uncovering speed. As shown in fig. 1, in the present embodiment, the first work is a water tank 20, the second work is a water pump 30, and the coolant circulates between the water tank 20 and the cooling chamber 1 by the water pump 30.

A stopper 139 is provided between the inner pan 12 and the coolant inlet 138 so that the coolant cannot be directly sprayed onto the inner pan 12.

With the technical solution of the present embodiment, when the cooling fluid enters the cooling chamber 1 from the cooling fluid inlet 138, the cooling fluid is stopped by the stopper 139. The cooling liquid passing the stopper is not directly contacted with the inner pan 12. As the liquid level of the cooling liquid entering the cooling cavity 1 rises, the inner pot 12 is slowly immersed into the cooling liquid, so that the amount of generated steam is greatly reduced, the amount of steam entering other areas in the pot body 10 is reduced as much as possible, adverse effects of the steam on the cooking appliance are reduced, and the use experience of a user is improved.

As shown in fig. 27 and 28, in the present embodiment, the stopper 139 is a stopper piece. The structure is simple and easy to process.

In the present embodiment, the bottom 132 and the cylindrical body 136 are integrally formed. The structure is simple and easy to process. In addition, the above structure reduces the step of mounting the cylindrical body 136 on the bottom 132, thereby improving the production efficiency.

The heating device 13 in the present embodiment has a bottom 132 and a cylindrical body 136 located on the bottom 132, wherein the bottom 132 is provided with a coil for heating the inner pot 12, and the cylindrical body 136 is used for heat preservation. Preferably, in the present embodiment, the bottom 132 and the cylinder 136 are integrally formed, but those skilled in the art will appreciate that the bottom 132 and the cylinder 136 may be separately formed, i.e. the bottom 132 is a heating plate, the cylinder 136 is a heat-insulating cover, and the heating plate and the heat-insulating cover are assembled to form the heating device body 131.

The heating device 13 includes a heating device body 131 and a bracket 137, and the heating device body 131 includes a bottom 132 and a cylindrical body 136.

As shown in fig. 14, 21 and 29, in the present embodiment, the water pump 30 includes a first water pump 31 and a second water pump 32, the first water pump 31 communicates with the water tank 20 and the cooling chamber 1, the cooling liquid in the water tank 20 enters into the cooling chamber 1 through the first water pump 31, the second water pump 32 communicates with the water tank 20 and the cooling chamber 1, and the cooling liquid in the cooling chamber 1 enters into the water tank 20 through the second water pump 32.

By applying the technical scheme of the embodiment, the second water pump 32 pumps out the cooling liquid in the cooling cavity 1, so that the cooling liquid in the cooling cavity 1 can be pumped out as much as possible under the action of the self gravity and the external force generated by the second water pump 32, and the service life of the cooking utensil is ensured. In addition, since the first water pump 31 can control the flow of the cooling liquid entering the cooling cavity 1, and the second water pump 32 can control the flow of the cooling liquid flowing out of the cooling cavity 1, the liquid level of the cooling liquid can be ensured to be in a preset range, and the cooling liquid is prevented from overflowing the cooling cavity, so that the use experience of a user is improved, and the problem that the use experience of the user of the cooking appliance in the prior art is poor is solved.

In this embodiment, the cooking appliance further includes a control part. The control part is electrically connected with the first water pump 31 and the second water pump 32, when the control part receives a first signal, the first water pump 31 works, when the control part receives a second signal, the control part controls the first water pump 31 and the second water pump 32 to work simultaneously so that cooling liquid can circulate in the water tank 20 and the cooling cavity 1, when the control part receives a third signal, the first water pump 31 stops working, the second water pump 32 continues to work, and when the control part receives a fourth signal, the second water pump 32 stops working. Specifically, when the pressure in the inner pot 12 needs to be quickly reduced, the first water pump 31 is started, the first water pump 31 starts to feed the cooling liquid into the cooling cavity 1, and when the liquid level of the cooling liquid in the cooling cavity 1 reaches a preset range or the first water pump 31 feeds the cooling liquid for a preset time, the second water pump 32 is started. At this time, the first water pump 31 continues to feed the cooling liquid into the cooling chamber 1, and the second water pump 32 starts to discharge the cooling liquid in the cooling chamber 1. The scheme can ensure the circulation of the water tank 20 and the cooling liquid in the cooling cavity 1, thereby realizing the purpose of quickly reducing the temperature of the inner pot 12. Further, since the flow rates of pumping and extracting the cooling liquid by the first water pump 31 and the second water pump 32 are controllable, the cooling liquid in the cooling chamber 1 can be always maintained within a predetermined range, and the cooling liquid is prevented from overflowing from the cooling chamber 1. When the temperature of the inner pan 12 is reduced to a predetermined temperature, the first water pump 31 may be stopped, i.e., the first water pump 31 stops introducing the cooling liquid into the cooling chamber 1. The second water pump 32 continues to operate, and at this time, the cooling liquid in the cooling cavity 1 is pumped into the water tank 20 entirely to realize recovery of the cooling liquid.

As shown in fig. 26, in the present embodiment, the cooling chamber 1 communicates with the outside.

As shown in fig. 26, in the present embodiment, the heating device 13 includes a bottom 132 and a cylindrical body 136 extending upward from the bottom 132, a cooling chamber 1 accommodating a cooling liquid is formed between the inner pan 12 and the bottom 132 and the cylindrical body 136 of the heating device 13, and the top of the inner pan 12 and the top of the cylindrical body 136 form an opening to communicate with the outside. The structure ensures that the volume of the cooling cavity 1 is larger, and the outer surface of the inner pot 12 can be contacted with the cooling liquid in the cooling cavity 1 as much as possible, thereby improving the uncovering speed.

In the present embodiment, the first water pump 31 is a one-way pump. The structure is simple and the cost is low.

In the present embodiment, the first water pump 31 is a bi-directional pump. When the pressure in the inner pot 12 needs to be quickly reduced, the first water pump 31 is started, and the first water pump 31 starts to feed cooling liquid into the cooling cavity 1. When the temperature of the inner pot 12 is reduced to a predetermined temperature, the first water pump 31 may be reversely started, i.e., the first water pump 31 stops introducing the cooling liquid into the cooling chamber 1. The second water pump 32 continues to operate, and at this time, the cooling liquid in the cooling cavity 1 is pumped into the water tank 20 entirely to realize recovery of the cooling liquid. When the cooling liquid in the cooling chamber 1 is lowered to a predetermined height or is entirely drawn out, the first water pump 31 may be reversely started so that the cooling liquid in the first water pump 31 can be entirely recovered into the water tank 20. The above structure allows no residual coolant in the first water pump 31, thereby improving the life of the first water pump 31.

In the present embodiment, the second water pump 32 is a one-way pump. The structure is simple and the cost is low.

As shown in fig. 29 to 31, in the present embodiment, the water pump 30 is located at the front of the pan body 10, and the axis of the water pump 30 is disposed at a predetermined angle to the axis of the pan body 10 in the front-rear direction.

With the technical solution of the present embodiment, since the water pump 30 is located at the front portion of the pot body 10, the length of the water pump 30 in the front-rear direction of the pot body 10 determines the overall length of the cooking appliance in the front-rear direction. Therefore, in the present embodiment, the axis of the water pump 30 is disposed at a predetermined angle with respect to the axis of the pan body 10 in the front-rear direction. The above structure can shorten the length of the water pump 30 in the front-rear direction, i.e., shorten the length of the cooking appliance in the front-rear direction, thereby reducing the product volume of the cooking appliance and solving the problem of large volume of the cooking appliance in the prior art.

It should be noted that, in this embodiment, the cooking apparatus includes a pot body 10 and a pot cover covered on the pot body, one side of the pot cover is pivoted on the pot body 10, and the opposite side of the pot cover is clamped on the pot body 10 by a clamping structure.

The above structure enables the fourth communication pipe section 55 to be far away from the heating device 13 with higher temperature, thereby preventing the fourth communication pipe section 55 from being damaged by heat, and further ensuring the service life of the cooking utensil.

As shown in fig. 21, in the present embodiment, the cooking appliance includes the second communication pipe 50. The second communication pipe 50 includes a first communication pipe section 51, a second communication pipe section 52, and a second adaptor 53 connecting the first communication pipe section 51 and the second communication pipe section 52, the third communication pipe section 54 and the fourth communication pipe section 55 form the second communication pipe section 52, and the free end of the fourth communication pipe section 55 communicates with the water tank 20 through the first communication pipe section 51.

As shown in fig. 14 and 21, in the present embodiment, the cooking appliance includes a first communication pipe 40 and a first adapter 60. The first communication pipe 40 is disposed on the housing 11 and extends into the water tank 20. The first connection member 60 communicates the first communication pipe 40 with the second communication pipe 50, and the first communication pipe section 51 of the second communication pipe 50 communicates with the tank 20 through the first communication pipe 40.

As shown in fig. 31, in the present embodiment, the angle between the axis of the water pump 30 and the axis of the pan body 10 in the front-rear direction is between 8 degrees and 50 degrees. The above structure further enables the fourth communication pipe section 55 to be away from the heating device 13 having a higher temperature, thereby preventing the fourth communication pipe section 55 from being damaged by heat.

As shown in fig. 31, in the present embodiment, the water pump 30 is located at a side of the bottom of the housing 11 near the water tank 20. The above structure enables the water pump 30 to be kept away from the heating device 13 as much as possible, so that the temperature of the coolant in the water pump 30 and the second communication pipe 50 is kept as low as possible, thereby ensuring the heat absorbing capacity of the coolant. In addition, the water pump 30 is disposed below the water tank 20 having a low temperature so that the water pump 30 can be far away from a high temperature area as much as possible, thereby securing the service life of the water pump 30.

As shown in fig. 31, in the present embodiment, the first water pump 31 and the second water pump 32 are symmetrical with respect to the axis of the pan body 10 in the front-rear direction. The structure is simple and convenient to assemble.

As shown in fig. 30, in this embodiment, the pan body 10 further includes a bottom shell 16 located below the outer shell 11, the heating device 13, and the inner pan 12, and a heat dissipation hole 161 is disposed on the bottom shell 16, where a projection of the heat dissipation hole 161 on a horizontal plane is not coincident with a projection of the water pump 30 on the horizontal plane. The above structure makes the user's finger not touch the water pump 30 even if it is inserted into the heat radiation hole 161, thereby satisfying the safety requirements. Fig. 30 is a schematic bottom view of the pan body, and the heat dissipation holes 161 can be seen from the figure, and the two sides of the heat dissipation holes 161 are provided with baffles for shielding the water pump 30. If the axis of the water pump 30 is in the same direction as the axis of the pan body 10 in the front-rear direction, the length of the baffle plate in the front-rear direction of the pan body 10 will be longer, so that the area of the heat radiation hole 161 becomes smaller. And if the axis of the water pump 30 is disposed at a predetermined angle with respect to the axis of the pan body 10 in the front-rear direction. The length of the water pump 30 in the front-rear direction of the pot body 10 will be short, and the length of the baffle plate shielding the water pump 30 in the front-rear direction of the pot body 10 will be shortened accordingly, so that the area of the heat radiation hole 161 will be set larger. Therefore, the heat radiation capability of the cooking appliance can be improved by providing the axis of the water pump 30 at a predetermined angle with respect to the axis of the pan body 10 in the front-rear direction.

As shown in fig. 29 and 30, in the present embodiment, the pan body 10 includes a bottom case 16 provided below the housing 11, and the bottom case 16 is installed after the water pump 30 is installed on the housing 11.

By applying the technical scheme of the embodiment, when the water pump 30 is installed, the water pump 30 is firstly installed on the shell 11, and at this time, the components connected with the water pump 30 are fixed. Finally, the bottom shell 16 is covered below the shell 11 to finish the installation. In the above structure, since the water pump 30 is not on the bottom case 16, the interference between the water pump 30 and the housing 11 or other components during the installation of the bottom case 16 is avoided, thereby facilitating the installation, improving the installation efficiency, and solving the problem of inconvenient installation of the cooking appliance in the prior art. Further, since the water pump 30 is mounted on the housing 11 in advance, the position of the pipeline connected to the water pump 30 can be fixed in advance, and then the bottom case 16 is covered under the housing 11. That is, after the bottom case 16 is installed, the position of the pipeline connected to the water pump 30 will not be shifted, so that the above structure can avoid the pipeline contacting the heating device 13, prevent the pipeline from being damaged by heat, and finally ensure the service life of the cooking appliance.
