Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a cleaning mechanism and a cooking device. Background Art

[0002] When the cooking device is cooking various ingredients, especially meat ingredients, oil stains are likely to remain on the cavity wall of the cooking cavity, so it is necessary to clean the cavity wall of the cooking cavity in time after cooking is completed.

[0003] In the prior art, the cleaning mechanism includes a nozzle, a pipeline, a water tank and a water pump. The nozzle is installed inside the cooking cavity. The water pump can extract the cleaning liquid in the water tank and transport it to the nozzle through the pipeline. The nozzle then sprays the cleaning liquid onto the cavity wall of the cooking cavity.

[0004] However, when the above-mentioned nozzle is fixed in the cooking cavity, it can only spray cleaning liquid in a specific direction, resulting in low cleaning efficiency. If the nozzle is rotatably connected to the cooking cavity, a driving element such as a motor needs to be separately provided. Although the nozzle can be driven to rotate, the space required for the cleaning mechanism is increased due to the provision of the driving element, which seriously affects the arrangement of other structures such as the heating module in the cooking device and also increases the overall energy consumption. Utility Model Content

[0005] The purpose of the utility model is to provide a cleaning mechanism and a cooking device, which solves the problem in the prior art that the cleaning efficiency is low when the nozzle is fixed, and a driving element needs to be separately set when it is rotatably connected, which not only increases the space required, affects the arrangement of other structures in the cooking device, but also increases the overall energy consumption.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] In a first aspect, the utility model provides a cleaning mechanism, which comprises:

[0008] A shower head, wherein the shower head has a liquid storage chamber and a cleaning hole, wherein a plurality of cleaning holes are provided, and within a plane perpendicular to the rotation axis of the shower head, an axial projection of at least part of the cleaning holes and a radial projection of the shower head form an angle α, wherein α>0°, so that the cleaning liquid within the liquid storage chamber can be sprayed out through the cleaning holes and generate a recoil force that drives the shower head to rotate, and at least part of the cleaning liquid sprayed out of the cleaning holes is sprayed toward the top wall of the inner tank.

[0009] Optionally, the shower head comprises:

[0010] The spray part is in the shape of an elongated strip, and a plurality of the spray parts are distributed at intervals around the rotation axis of the spray head, and a plurality of the cleaning holes are distributed at intervals on each of the spray parts.

[0011] Optionally, the shower head comprises:

[0012] The spray part is in a table shape and at least part of the cleaning holes are arranged on the top wall of the spray part. The cleaning holes arranged on the top wall of the spray part have a first end connected to the liquid storage chamber and a second end connected to the inside of the inner tank. The distance between the axis of at least part of the cleaning holes arranged on the top wall of the spray part and the rotation axis of the spray head gradually increases from the first end to the second end.

[0013] Optionally, in a plane perpendicular to the rotation axis of the spray head, a projection area of ​​the spray portion is less than or equal to 1 / 4 of a projection area of ​​the inner tank.

[0014] Optionally, the cleaning mechanism further comprises:

[0015] A connecting component is arranged on the inner tank, the connecting component has a guide hole, one end of which is connected to the injection pipe, the spray head is arranged on the connecting component, and the other end of the guide hole is connected to the liquid storage chamber to inject the cleaning liquid into the liquid storage chamber.

[0016] Optionally, the connection component includes:

[0017] A mounting seat having the guide hole;

[0018] A connecting sleeve, arranged on a side of the mounting seat away from the injection pipe; and

[0019] The rotating member is inserted into the connecting sleeve and is rotatably connected with the connecting sleeve. The rotating member passes through one end of the connecting sleeve and is connected with the sprinkler head.

[0020] Optionally, the inner wall of the connecting sleeve has a stepped hole, and the rotating member includes:

[0021] A rotating ring, mounted on the step hole so that the rotating member can rotate relative to the connecting sleeve;

[0022] A connecting claw has one end fixedly connected to the rotating ring and the other end passing through the connecting sleeve and clamped to the shower head.

[0023] Optionally, a plurality of clamping blocks are provided in the inner spacer ring of the mounting seat, and a locking block that is suspended and matched with the clamping blocks is provided on the inner side of the connecting sleeve.

[0024] Optionally, the connection component includes:

[0025] A sealing ring is arranged in the connecting sleeve and abuts against the mounting seat to seal a gap between the mounting seat and the connecting sleeve.

[0028] The cleaning mechanism as described in any one of the first aspects is arranged in the inner container.

[0029] Beneficial effects of the utility model:

[0030] On the one hand, by setting a liquid storage chamber and a cleaning hole, the liquid storage chamber can accommodate pressurized cleaning liquid. When the cleaning liquid fills the liquid storage chamber, the cleaning liquid will enter the cleaning hole and be sprayed out of the cleaning hole. When spraying, the pressure of the cleaning liquid will react to the cleaning hole to generate a recoil force, and the direction of the recoil force is the same as the axial direction of the cleaning hole. Taking the spray head set in the upper area of ​​the inner tank as an example, due to the existence of the angle α, in the projection in the horizontal plane, the recoil force can be divided into two components, one component is parallel to the radial direction of the spray head, and the other component is perpendicular to the radial direction of the spray head. The component can drive the spray head to rotate. During the rotation of the spray head, at least part of the cleaning liquid sprayed from the cleaning hole can be sprayed toward the top wall of the inner tank, while the cleaning liquid from the remaining cleaning holes is sprayed toward the side wall of the inner tank, so as to successfully complete the cleaning of the inner tank. In this way, when the cleaning mechanism is in use, it only needs to rely on the pre-designed angle α to enable the spray head to continuously rotate during the continuous liquid injection process, so as to smoothly spray the cleaning liquid to the side wall and top wall of the inner tank, so that the cleaning liquid can fully cover the inner wall of the inner tank, and the inner tank is cleaned with high efficiency. In addition, there is no need to set up a driving element, which can not only save space and reserve space for the arrangement of other structures such as the heating module, but also reduce the overall energy consumption and improve the energy-saving effect of the cleaning structure.

[0031] Secondly, by arranging the cleaning mechanism inside the inner pot, the hydraulic pressure of the cleaning liquid itself can be used to drive the cleaning rack mechanism to rotate, which not only allows the cleaning liquid to cover the inner wall of the inner pot more comprehensively, but also makes it possible for the cooking device to no longer need to be provided with a driving unit for driving the cleaning mechanism to rotate. While saving space, it can also save energy consumption for cleaning the inner pot, effectively enhancing the energy saving performance of the cooking device. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The utility model embodiment discloses a cleaning mechanism and a cooking device.

[0047] Embodiment 1

[0048] Reference Figures 1 to 4 The cleaning mechanism includes a spray head 1. The spray head 1 has a liquid storage chamber 11 and a cleaning hole 12. A plurality of cleaning holes 12 are provided. In a plane perpendicular to the rotation axis of the spray head 1, an axial projection of at least part of the cleaning holes 12 and a radial projection of the spray head 1 have an angle α, α>0°, so that the cleaning liquid in the liquid storage chamber 11 can be sprayed out through the cleaning holes 12 and generate a recoil force to drive the spray head 1 to rotate, and at least part of the cleaning liquid sprayed from the cleaning holes 12 is sprayed toward the top wall of the inner tank 3.

[0049] Specifically, the spray head 1 is a closed structure, and its interior is hollow as a liquid storage chamber 11. The liquid storage chamber 11 is connected to the liquid injection device to accommodate the pressurized cleaning liquid. The spray head 1 is rotatably connected to the interior of the inner liner 3. It can be located in the upper area of ​​the inner liner 3, or in the lower area of ​​the inner liner 3, or can be set on any vertical wall of the inner liner 3. A connecting structure can be set on the inner liner 3 to connect the spray head 1. While realizing the rotational connection of the spray head, the connecting structure is also connected to the pipeline of the liquid injection device, so that the cleaning liquid can be continuously injected into the liquid storage chamber 11 during the rotation of the spray head 1. The cleaning hole 12 is partially set toward the top wall of the inner liner 3, so that the cleaning liquid can contact the top wall of the inner liner 3 after being sprayed out, so as to clean the top wall of the inner liner 3.

[0050] Taking the example of the spray head 1 being arranged in the upper area of ​​the inner tank 3, the rotation axis of the spray head 1 is the vertical direction, the plane perpendicular to the rotation axis is the horizontal plane, the axial direction of the cleaning hole 12 is the extension direction when the cleaning hole 12 is opened, and the extension direction is linear. There is an angle α between the axial projection of the cleaning hole 12 in the horizontal plane and the radial projection of the spray head 1 in the horizontal plane, that is, the projections of the two in the horizontal plane are not parallel. The specific size of α can be calculated based on the size of the driving force actually required, and the utility model does not limit it here.

[0051] By providing the liquid storage chamber 11 and the cleaning hole 12, the liquid storage chamber 11 can accommodate pressurized cleaning liquid. When the cleaning liquid fills the liquid storage chamber 11, the cleaning liquid will enter the cleaning hole 12 and be sprayed out from the cleaning hole 12. When spraying out, the pressure of the cleaning liquid will react to the cleaning hole 12 to generate a recoil force, and the direction of the recoil force is the same as the axial direction of the cleaning hole 12. Taking the spray head 1 arranged in the upper area of ​​the inner tank 3 as an example, due to the existence of the angle α, in the projection in the horizontal plane, the recoil force can be divided into two components, one component is parallel to the radial direction of the spray head 1, and the other component is perpendicular to the radial direction of the spray head 1. The component forces can drive the spray head 1 to rotate. During the rotation of the spray head 1, at least part of the cleaning liquid sprayed from the cleaning hole 12 can be sprayed toward the top wall of the inner tank 3, while the cleaning liquid from the remaining cleaning holes 12 is sprayed toward the side wall of the inner tank 3, so as to successfully complete the cleaning of the inner tank 3. In this way, when the cleaning mechanism is in use, it only needs to rely on the pre-designed angle α to enable the spray head 1 to continuously rotate during the continuous liquid injection process, so as to smoothly spray the cleaning liquid to the side wall and top wall of the inner tank 3, so that the cleaning liquid can fully cover the inner side of the inner tank 3, and the inner tank 3 is cleaned with high efficiency. In addition, there is no need to set up a driving element, which can not only save space and reserve space for the arrangement of other structures such as the heating module, but also reduce the overall energy consumption and improve the energy-saving effect of the cleaning mechanism.

[0052] Optionally, the shower head 1 comprises a shower part 13. The shower part 13 is in a long strip shape and is distributed in plurality around the rotation axis of the shower head 1 at intervals, and each shower part 13 has a plurality of cleaning holes 12 distributed in intervals.

[0053] Specifically, the spray head 1 has a plurality of spray parts 13, and the plurality of spray parts 13 are arranged in a ring at intervals around the rotation axis of the spray head 1. In the present embodiment, three spray parts 13 are provided. A spray block 131 is convexly provided on the surface of the spray part 13, and the two can be an integrated structure. In a plane perpendicular to the rotation axis of the spray head 1, there is an angle α between the projection of the extension direction of the spray block 131 and the projection of the length direction of the spray part 13, and the cleaning hole 12 is opened through the spray block 131 and the axial direction of the cleaning hole 12 is parallel to the extension direction of the spray block 131. Taking the spray head 1 arranged in the upper area of ​​the inner tank 3 as an example, in the horizontal plane, there is an angle α between the projection of the extension direction of the spray block 131 and the projection of the length direction of the spray part 13, and the axial direction of the cleaning hole 12 is parallel to the extension direction of the spray block 131, so that the axial projection of the cleaning hole 12 and the projection of the length direction of the spray part 13 can smoothly form an angle α.

[0054] The long strip-shaped spray portion 13 allows a certain space to exist between two adjacent spray portions 13, so that the heating module and other structures arranged on the top of the inner pot 3 can smoothly cook the food inside the inner pot 3. At the same time, multiple cleaning holes 12 are spaced apart along the length direction of the spray portion 13, and the distance between the cleaning holes 12 and the side walls of the inner pot 3 can be made smaller, thereby ensuring that the cleaning liquid can effectively flush the side walls of the inner pot 3 when sprayed from the cleaning holes 12, thereby improving the cleaning effect of the inner pot 3.

[0055] Optionally, a plurality of spray blocks 131 may be provided, and the plurality of spray blocks 131 are distributed at intervals in the spray part 13 , and at least some of the spray blocks 131 are inclined.

[0056] Specifically, only one cleaning hole 12 is provided on each spray block 131, and multiple spray blocks 131 can provide space for the opening of multiple cleaning holes 12. In order to better drive the spray head 1 to rotate, an inclined extending spray block 131 is provided at one end of the spray portion 13 away from the rotation axis of the spray head 1, and the extension direction of the spray block 131 at other positions can be parallel or perpendicular to the rotation axis of the spray head 1, so that the cleaning liquid can be directly sprayed onto the top wall and side walls of the inner tank 3, so as to further improve the cleaning effect of the inner tank 3.

[0057] Reference Figures 4 to 6 Optionally, the cleaning mechanism further includes a connecting component 2. The connecting component 2 is arranged on the inner tank 3, and has a guide hole 211, one end of which is connected to the injection pipe 4, and the spray head 1 is arranged on the connecting component 2, and the other end of which is connected to the liquid storage chamber 11 to inject the cleaning liquid into the liquid storage chamber 11.

[0058] Specifically, the connection component 2 is arranged on any side wall of the inner tank 3, the spray head 1 is rotatably connected to the connection component 2, and the connection component 2 can be fixed to the inner tank 3. The connection component 2 can also be divided into two parts, the first part is fixed to the inner tank 3, and the second part is rotatably connected to the first part, and the second part is fixedly connected to the spray head 1. Both of the above two connection components 2 can realize the rotation connection of the spray head 1 and continuously inject the cleaning liquid, and can be specifically designed according to the actual processing difficulty.

[0059] By providing the connection assembly 2, the cleaning liquid can be continuously injected into the guide hole 211 through the injection pipe 4 while the shower head 1 rotates, and the cleaning liquid smoothly enters the liquid storage chamber 11 along the guide hole 211. In this way, the cleaning liquid is continuously injected into the liquid storage chamber 11 during the rotation process, so that the cleaning process can be continuously performed.

[0060] Optionally, the connection assembly 2 includes a mounting seat 21, a connecting sleeve 22 and a rotating member 23. The mounting seat 21 has the above-mentioned guide hole 211; the connecting sleeve 22 is arranged on a side of the mounting seat 21 away from the injection pipe 4; the rotating member 23 is penetrated by the connecting sleeve 22 and is rotatably connected to the connecting sleeve 22, and the rotating member 23 passes through one end of the connecting sleeve 22 and is connected to the sprinkler head 1.

[0061] Specifically, the mounting seat 21 includes a fixed disk 212, which may be annular, and its edge position is fixed to the outer top wall of the inner liner 3 by fasteners such as bolts. A sealing ring 25 may be provided on the lower side of the fixed disk 212, and the sealing ring 25 is inserted into the protruding structure on the outer top of the inner liner 3, so that a sealed connection is formed between the fixed disk 212 and the inner liner 3. The top wall protrusion of the fixed disk 212 forms a connecting ring 213, and the bottom wall protrusion of the fixed disk 212 forms a connecting column 214. The connecting ring 213 is coaxial with the connecting column 214, and both have a through hole passing therethrough as a guide hole 211. The connecting ring 213 is inserted into the injection tube 4 to form a sealed connection, and the connecting column 214 extends into the inner liner 3, and the end of the connecting column 214 away from the fixed disk 212 is inserted into the connecting sleeve 22. The connection column 214 and the connection sleeve 22 are fixedly connected, and the fixing method can be a detachable connection method such as a snap connection, a threaded connection, or a non-detachable connection method such as welding or bonding.

[0062] The rotating member 23 is inserted into the connecting sleeve 22. In order to ensure smooth communication between the connecting hole and the guide hole 211, the end of the connecting column 214 inserted into the connecting sleeve 22 can be stepped, and the end with a smaller outer diameter is inserted into the rotating member 23 and connected to the sprinkler head 1, so that the guide hole 211 is smoothly connected with the liquid storage chamber 11.

[0063] By setting the mounting seat 21, the entire connecting assembly 2 can be set on the inner tank 3. By setting the connecting sleeve 22 and inserting a rotatable rotating part 23 in the connecting sleeve 22, it is convenient to connect with the spray head 1 to realize the rotation of the spray head 1. The setting of the guide hole 211 allows the cleaning liquid to be continuously injected into the liquid storage chamber 11 along the guide hole 211.

[0064] Optionally, the inner wall of the connecting sleeve 22 has a stepped hole, and the rotating member 23 includes a rotating ring 231 and a connecting claw 232. The rotating ring 231 is mounted on the stepped hole so that the rotating member 23 can rotate relative to the connecting sleeve 22; one end of the connecting claw 232 is fixedly connected to the rotating ring 231, and the other end passes through the connecting sleeve 22 and is clamped to the sprinkler head 1.

[0065] Specifically, the rotating ring 231 is located inside the connecting sleeve 22, and its bottom surface overlaps the step surface of the inner wall of the connecting sleeve 22. A connecting claw 232 is arranged on the bottom surface of the rotating ring 231. The two can be an integrated structure, and a plurality of connecting claws 232 can be distributed around the circumference of the rotating ring 231. In this embodiment, four connecting claws 232 are distributed at equal intervals. The connecting claw 232 extends along the axial direction of the connecting sleeve 22 and extends out of the connecting sleeve 22. One end of the connecting claw 232 extending out of the connecting sleeve 22 has a hook. A clamping block 14 is arranged on the upper side of the sprinkler head 1. A clamping hole 141 is opened on the clamping block 14 corresponding to each connecting claw 232, and the hook can be inserted into the clamping hole 141 to form a clamping fixation. The interior of the clamping block 14 is hollow, and its inner wall is flush with the inner wall of the rotating ring 231, so that the end with a smaller outer diameter of the connecting column 214 can extend into the clamping block 14.

[0066] By overlapping the rotating ring 231 inside the connecting sleeve 22, the entire rotating member 23 can be clamped in the connecting sleeve 22 to limit its axial displacement, and the connecting claws 232 extend into the corresponding clamping holes 141 to form a clamping fixation, so that the spray head 1 can be smoothly fixed to the rotating member 23. In this way, the rotation of the spray head 1 can be achieved while the cleaning liquid is continuously directed into the liquid storage chamber 11.

[0067] Optionally, a plurality of clamping blocks 215 are provided in the spacer ring of the mounting seat 21 , and a locking block 221 that is suspended and engaged with the clamping blocks 215 is provided on the inner side of the connecting sleeve 22 .

[0068] Specifically, in order to facilitate disassembly, the mounting seat 21 and the connecting sleeve 22 are fixedly connected in a detachable manner. A locking block 221 is provided on the inner wall of the connecting sleeve 22, and a clamping block 215 overlapped with the locking block 221 is provided on the outer wall of the connecting column 214. The clamping block 215 is in a "﹂" shape, and the locking block 221 can be inserted into the clamping block 215 so that the connecting sleeve 22 and the connecting column 214 remain relatively fixed. In this embodiment, four clamping blocks 215 and four locking blocks 221 are respectively provided. In other embodiments, the number can be designed according to the actual size of the connecting sleeve 22 and the mounting seat 21.

[0069] By providing the clamping block 215 and the locking block 221, after the connecting sleeve 22 is sleeved on the outside of the connecting column 214, the connecting sleeve 22 is rotated so that the locking block 221 is inserted into the clamping block 215, and the horizontal arm of the clamping block 215 can carry the locking block 221 to limit the axial displacement of the connecting sleeve 22 relative to the connecting column 214, while the vertical arm of the clamping block 215 can stop the locking block 221 to limit the rotation of the connecting sleeve 22 relative to the connecting column 214. In this way, the relatively fixed connection between the connecting sleeve 22 and the mounting seat 21 can be achieved through a simple clamping structure, and the two can be quickly disassembled when disassembly is required.

[0070] Optionally, the connection assembly 2 includes a sealing ring 24 . The sealing ring 24 is disposed in the connection sleeve 22 and abuts against the mounting seat 21 to seal a gap between the mounting seat 21 and the connection sleeve 22 .

[0071] Specifically, two steps may be provided inside the connecting sleeve 22, the lower step is used to overlap with the rotating ring 231, and the upper step is used to place the sealing ring 24, and the top wall of the sealing ring 24 abuts against the step surface of the connecting column 214. The sealing ring 24 may be made of a rubber material with a certain elasticity, or may be made of other materials that meet the requirements, and the present invention does not limit this.

[0072] By providing the sealing ring 24, the gap between the connecting sleeve 22 and the connecting column 214 can be sealed to ensure good sealing between the connecting sleeve 22 and the mounting seat 21. The sealing ring 24 may not contact the rotating ring 231 to reduce the friction force on the rotating ring 231 when rotating, ensuring that the rotating ring 231 can rotate smoothly.

[0073] Embodiment 2

[0074] On the basis of the first embodiment, the difference between this embodiment and the first embodiment lies in the different specific structure of the shower head 1 .

[0075] Reference Figure 7 and Figure 8Optionally, the shower head 1 includes a shower part 13. The shower part 13 is in a table shape and at least part of the cleaning holes 12 are arranged on the top wall of the shower part 13. The cleaning holes 12 arranged on the top wall of the shower part 13 have a first end connected to the liquid storage chamber 11 and a second end connected to the inside of the inner tank 3. The distance between the axis of at least part of the cleaning holes 12 arranged on the top wall of the shower part 13 and the rotation axis of the shower head 1 gradually increases from the first end to the second end. In a plane perpendicular to the rotation axis of the shower head 1, the projection area of ​​the shower part 13 is less than or equal to 1 / 4 of the projection area of ​​the inner tank 3.

[0076] Specifically, the inside of the spray part 13 is hollow as a liquid storage chamber 11, and a through hole is formed through its side wall as a cleaning hole 12. The side wall of the spray part 13 can be arranged parallel to the inner wall of the inner pot 3, or can be arranged obliquely relative to the inner wall of the inner pot 3. It can be specifically designed according to the range in which the cleaning liquid needs to be sprayed, and the utility model does not limit this. In order to avoid the truncated cone-shaped spray part 13 from interfering with the heating module on the top wall of the inner pot 3 and affecting the cooking of the food, the size of the spray part 13 is relatively small relative to the size of the top wall of the inner pot 3. Calculated by the projected area in the plane perpendicular to the rotation axis of the spray head 1, the projected area of ​​the spray part 13 is less than or equal to 1 / 4 of the projected area of ​​the inner pot 3. The distance between the second end of the axis of the cleaning hole 12 and the rotation axis of the spray head 1 is greater than the distance between the first end and the rotation axis of the spray head 1, so that the cleaning hole 12 can extend obliquely toward the direction close to the side wall of the inner pot 3. Instead, only some of the cleaning holes 12 can be arranged to extend obliquely, so that the inclined liquid can not only be sprayed out obliquely, but also sprayed directly at the top of the inner liner 3, thereby effectively increasing the coverage of the cleaning liquid. The specific number of cleaning holes 12 arranged obliquely can be designed according to the actual coverage range required, and this application does not limit this.

[0077] The cleaning hole 12 is arranged to extend obliquely so that the cleaning liquid can be sprayed obliquely toward the side wall of the inner pot 3 when spraying. In order to achieve the oblique extension with the cleaning hole, the top wall of the spray part 13 can be extended obliquely relative to the top wall of the inner pot 3, so that the distance between the top wall of the spray part 13 and the top wall of the inner pot 3 increases from the side close to the rotation axis of the spray part 13 to the side close to the edge position of the spray part 13.

[0078] It is also possible to set the top wall of the spray part 13 parallel to the top wall of the inner tank 3, and to open the cleaning hole 12 separately at an angle to achieve this. There is an angle greater than 0° between the axial direction of the cleaning hole 12 and the wall thickness direction of the spray part 13, so that the cleaning hole 12 is not opened perpendicular to the spray part 13, that is, the cleaning hole 12 extends obliquely, so that the distance between the axis of the cleaning hole 12 and the rotation axis of the spray head 1 gradually increases from the first end to the second end. If the extension line of the inclined cleaning hole 12 does not intersect with the extension line of the rotation axis of the spray part 13, then in the plane perpendicular to the rotation axis of the spray part 13, the axial projection of the cleaning hole 12 and the radial projection of the spray part 13 must be able to form an angle α. The specific size of α can be calculated based on the size of the force actually required to drive, and the utility model does not limit it here.

[0079] By setting the spray part 13 as the spray head 1, the size of the spray head 1 can be reduced to reduce the occupation of the internal space of the inner pot 3, ensuring that there will be no interference with the heating module and other structures on the top of the inner pot 3, so as to ensure that cooking can proceed smoothly. The inclined cleaning holes allow the cleaning liquid to be sprayed out obliquely, so that the cleaning liquid can cover a larger range, ensuring a better cleaning effect on the inner pot 3. Moreover, the spray part 13 can form a centralized arrangement of the multiple cleaning holes 12, so that the recoil force generated by the multiple cleaning holes 12 when spraying the cleaning liquid is more concentrated, so as to smoothly drive the spray part 13 to rotate.

[0080] Optionally, at least part of the cleaning holes 12 are opened on the surface of the spray portion 13 opposite to the side wall of the inner container 3 .

[0081] Specifically, cleaning holes 12 are opened on the side walls of the spray part 13, so that when the cleaning holes 12 spray cleaning liquid, the cleaning liquid can directly contact the side walls of the inner tank 3, so as to clean the top wall and side walls of the inner tank 3 at the same time, effectively improving the cleaning effect of the inner tank 3.

[0082] The cooking device comprises an inner pot 3 and a cleaning mechanism in any of the above embodiments. The inner pot 3 has a cooking cavity for cooking food. The cleaning mechanism is arranged in the inner pot 3.

[0083] By arranging the cleaning mechanism inside the inner pot 3, the hydraulic pressure of the cleaning liquid itself can be used to drive the cleaning rack mechanism to rotate, which not only allows the cleaning liquid to cover the inner wall of the inner pot 3 more comprehensively, but also makes it unnecessary for the cooking device to be provided with a driving unit for driving the cleaning mechanism to rotate. While saving space, it can also save energy consumption for cleaning the inner pot 3, effectively enhancing the energy saving performance of the cooking device.

[0084] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
