[0049] Electric rice cookers generate steam during cooking, and to prevent excessive pressure inside the rice cooker, an air vent is usually provided on the lid. However, when cooking food containing soup, the boiling soup will generate foam on the water surface, and the rising foam may block the air vent or overflow from the air vent, thus affecting the normal use of the rice cooker.

[0050] In order to solve the above problems, Figures 1 to 12 As shown, the utility model provides an electric rice cooker to achieve an anti-overflow effect.

[0051] In the illustrated embodiment, the electric rice cooker is an embedded electric rice cooker. Of course, in other embodiments, the electric rice cooker can also be a tabletop electric rice cooker or other types of electric rice cookers, and the utility model embodiment does not make specific restrictions here. For ease of description, the embedded electric rice cooker is used as an example for description below.

[0052] like Figure 1 to Figure 2As shown, the embedded electric rice cooker includes a main body 1, a rice adding device 2, a cooking device 3, an opening and closing device 4 and a control device (not shown), wherein: the main body 1 includes a shell 11 and a mounting seat 12 and a top seat 16 arranged in the shell 11, and the side of the shell 11 is provided with an opening 111; the rice adding device 2 is arranged in the shell 11, and is provided with a feeding port 21; the cooking device 3 is arranged in the shell 11 through the opening 111 and can be pulled out and pulled, and is located below the top seat 16, the cooking device 3 includes a pot body 31 and a pot cover 32, the pot cover 32 can be opened and closed in the pot body 31, and a feeding channel 321 is arranged in the pot cover 32, and the two ends of the feeding channel 321 can be communicated with the feeding port 21 and the pot body 31 respectively; the opening and closing device 4 is arranged in the pot cover 32, and is used to open or close the feeding channel 321; the control device is arranged in the main body 1 or the pot cover 32, and is used to control the operation of the embedded electric rice cooker.

[0053] In addition, a telescopic slide rail (not shown) is also provided in the housing 11. The cooking device 3 also includes a base 34, which is provided with a mounting cavity 341. The pot body 31 is detachably provided in the mounting cavity 341. The base 34 can be pushed into or pulled out of the housing 11 by sliding on the telescopic slide rail. The cooking device 3 also includes a heating element (not shown) provided at the bottom of the pot body 31 and used to heat the pot body 31. The mounting seat 12 can be provided at a side of the housing 11 opposite to the opening 111, and is provided with a power supply (not shown) and a third coupler 17 and other components electrically connected to each other. The control device is preferably provided on the mounting seat 12 and is electrically connected to the third coupler 17. A fourth coupler 39 is provided on the base 34. When the base 34 is pushed into the housing 11, the fourth coupler 39 is coupled with the third coupler 17, so that the heating element and other components on the cooking device 3 can be electrically connected to the control device and the power supply through the fourth coupler 39 and the third coupler 17. When the base 34 is pulled out of the housing 11 , the fourth coupler 39 is separated from the third coupler 17 .

[0054] like Figure 1 As shown, in one embodiment, the rice adding device 2 is arranged on the top seat 16, that is, the rice adding device 2 is located above the cooking device 3, and the discharge port 21 can be directly connected to the discharge channel 321, and the rice in the rice adding device 2 can fall into the discharge channel 321 through the discharge port 21 under the action of gravity. Of course, in other embodiments, the rice adding device 2 can also be arranged in parallel with the cooking device 3, and the discharge port 21 and the discharge channel 321 are connected through a pipeline, and the rice in the rice adding device 2 can be sucked into the discharge channel 321 through the discharge port 21 and the pipeline by a driving element such as an air pump.

[0055] like Figures 4 to 5As shown, in the illustrated embodiment, the pot cover 32 is detachably connected to the pot body 31. So that the user can clean the pot body 31 or the pot cover 32 separately after disassembly, and the operation is simple and convenient. The base 34 is also provided with a storage cavity 342 arranged side by side with the installation cavity 341, and the cooking device 3 also includes a storage box 35 detachably arranged in the storage cavity 342. The user can place the disassembled pot cover 32 in the storage box 35 to avoid occupying the space on the kitchen countertop. At the same time, the condensed water remaining on the pot cover 32 will drip into the storage box 35 to avoid contaminating the kitchen countertop. The storage box 35 is detachably arranged so that the user can pour the condensed water in the storage box 35 and clean the storage box 35. Alternatively, the storage box 35 can also be used to place other items such as rice spoons, and items such as the pot cover 32 can also be placed directly in the storage cavity 342.

[0056] Of course, in other embodiments, the pot cover 32 may also be rotatably connected to the pot body 31 , and the user can control the pot cover 32 to flip relative to the pot body 31 to open or close the pot body 31 .

[0057] like Figure 1 to Figure 2 As shown, specifically, the main body 1 further includes a driving assembly 13 and a first coupler 14 disposed on the mounting seat 12, the driving assembly 13 is connected to the first coupler 14, and is used to drive the opening and closing device 4; the cooking device 3 further includes a second coupler 33 disposed on the pot cover 32 and connected to the opening and closing device 4, and when the cooking device 3 is pushed into the housing 11, the first coupler 14 is coupled with the second coupler 33. After the pot cover 32 is covered on the pot body 31 and the cooking device 3 is pushed into the housing 11, the second coupler 33 is coupled with the first coupler 14, and the opening and closing device 4 is connected to the driving assembly 13 through the first coupler 14 and the second coupler 33. When it is necessary to add rice, the driving assembly 13 drives the opening and closing device 4 to open the material discharge channel 321, and the rice in the rice adding device 2 can fall into the pot body 31 through the material discharge port 21 and the material discharge channel 321 in sequence. After the rice is added, the driving assembly 13 drives the opening and closing device 4 to close the material discharge channel 321, and the rice cannot fall into the pot body 31. When the cooking device 3 is pulled out of the housing 11, the first coupler 14 and the second coupler 33 are disengaged. The driving assembly 13 and the control device are both arranged on the mounting seat 12 of the main body 1, and can control the opening and closing device 4 on the pot cover 32 to move when the first coupler 14 and the second coupler 33 are coupled, so that the driving assembly 13 can be prevented from increasing the volume and weight of the pot cover 32, making it convenient for the user to take or close the pot cover 32, and no electrical components are arranged on the pot cover 32, which can also facilitate the user to clean the pot cover 32.

[0058] like Figure 3 and Figure 6As shown, the driving assembly 13 includes a driving rod 131, one end of which is slidably disposed on the first coupler 14; the opening and closing device 4 includes an opening and closing member 41 and a push rod 42, the opening and closing member 41 is slidably disposed on the unloading channel 321, one end of the push rod 42 is slidably disposed on the second coupler 33, and the other end is connected to the opening and closing member 41; when the first coupler 14 is coupled with the second coupler 33, the driving rod 131 can push against the push rod 42. When adding rice, the driving rod 131 slides in the first coupler 14 toward the side close to the push rod 42, and pushes against the push rod 42, so that the push rod 42 slides in the second coupler 33 toward the side close to the opening and closing member 41, and drives the opening and closing member 41 to open the material discharge channel 321; after adding rice, the driving rod 131 slides in the first coupler 14 toward the side away from the push rod 42, and the push rod 42 slides in the second coupler 33 toward the side away from the closing member 41, so that the opening and closing member 41 closes the material discharge channel 321. The structure of the driving assembly 13 and the opening and closing device 4 is simple, so that the structure of the first coupler 14 and the second coupler 33 is also relatively simple, which is convenient for production and processing.

[0059] When the driving rod 131 does not push against the push rod 42, the driving rod 131 and the push rod 42 may contact each other or have a certain distance therebetween, as long as the driving rod 131 can contact and push against the push rod 42 when sliding toward the side close to the push rod 42.

[0060] like Figure 3 As shown, the opening and closing device 4 also includes a bracket 43 disposed on the inner wall of the material discharge channel 321, and the opening and closing member 41 is slidably disposed on the bracket 43. Along the extension direction of the material discharge channel 321, the opening and closing member 41 can slide out or retract into the material discharge channel 321 to open or close the material discharge channel 321; the push rod 42 includes a first rod body portion 421 and a push block portion 422. One end of the first rod body portion 421 is slidably disposed on the second coupler 33, and the push block portion 422 is connected to one end of the first rod body portion 421 away from the second coupler 33, and is used to push the opening and closing member 41. The bracket 43 is used to support the opening and closing member 41 and limit the movement path of the opening and closing member 41, so as to ensure that the opening and closing member 41 can accurately open or close the material discharge channel 321 when sliding out or retracting into the material discharge channel 321.

[0061] When the driving rod 131 slides in the first coupler 14 toward the side close to the push rod 42, it can push the first rod body portion 421 to slide in the second coupler 33 toward the side close to the opening and closing member 41, and the push block portion 422 slides together with the first rod body portion 421, and can push the opening and closing member 41 to slide out of the material discharge channel 321 to open the material discharge channel 321. When the driving rod 131 slides in the first coupler 14 toward the side away from the push rod 42, the first rod body portion 421 slides in the second coupler 33 toward the side away from the closing member 41, and the push block portion 422 slides together with the first rod body portion 421, so that the opening and closing member 41 slides back into the material discharge channel 321 to close the material discharge channel 321.

[0062] Furthermore, the opening and closing device 4 also includes a fifth sealing member 45 arranged on the periphery of the feeding channel 321. When the opening and closing member 41 closes the feeding channel 321, it can be abutted against the fifth sealing member 45 to improve the sealing performance of the opening and closing member 41 to the feeding channel 321, thereby preventing the rice in the rice adding device 2 from falling into the pot body 31 through the feeding channel 321.

[0063] like Figure 3 and Figure 7 As shown, the pot cover 32 includes a first cover body 324 and a second cover body 325 which are arranged to form an assembly cavity 328. The second coupler 33 and the first rod body portion 421 are both arranged in the assembly cavity 328. The first rod body portion 421 is located at one end of the second coupler 33 and is exposed from the assembly cavity 328, so that the driving rod 131 can push against the first rod body portion 421. The push rod 42 also includes a third elastic member 423 arranged between the first rod body portion 421 and the inner wall of the assembly cavity 328. When the first rod body portion 421 slides toward the side close to the opening and closing member 41, the third elastic member 423 is compressed; when the driving rod 131 slides toward the side away from the push rod 42, the driving rod 131 is separated from the first rod body portion 421, and the first rod body portion 421 slides and resets toward the side away from the closing member 41 under the action of the elastic force of the third elastic member 423. The third elastic member 423 may be configured as a compression spring and sleeved on the first rod portion 421 to limit the deformation direction of the compression spring.

[0064] like Figure 3As shown, in one embodiment, the opening and closing member 41 includes an abutting portion 411, and the opening and closing device 4 also includes a first elastic member 44 disposed between the abutting portion 411 and the bracket 43. When the opening and closing member 41 extends out of the feeding channel 321, the first elastic member 44 is compressed. When the first rod body portion 421 slides toward the side away from the closing member 41 in the second coupler 33, the push block portion 422 slides together with the first rod body portion 421 toward the side away from the closing member 41, and the push block portion 422 is separated from the opening and closing member 41. The opening and closing member 41 can slide back to the feeding channel 321 under the elastic force of the first elastic member 44 to close the feeding channel 321. Of course, when the opening and closing member 41 is in a closed state, the first elastic member 44 can also be in a compressed state to improve the stability of the opening and closing member 41 in the closed state, thereby improving the sealing performance of the opening and closing member 41 to the feeding channel 321. The first elastic member 44 may be configured as a compression spring and sleeved on the opening and closing member 41 to limit the deformation direction of the compression spring.

[0065] Of course, in other embodiments, the push block portion 422 and the opening and closing member 41 can also be connected by a flexible cable. When the push block portion 422 slides together with the first rod body portion 421 toward the side away from the closing member 41, the flexible cable can pull the opening and closing member 41, so that the opening and closing member 41 interactively retracts into the discharge channel 321.

[0066] like Figure 3 and Figure 7 As shown, the push block portion 422 includes a first inclined surface 4221 facing the opening and closing member 41, and the first inclined surface 4221 gradually tilts upward from the first rod body portion 421 to the opening and closing member 41. When the push block portion 422 slides toward the side close to the opening and closing member 41, the first inclined surface 4221 cooperates with the opening and closing member 41 and gradually pushes the opening and closing member 41 downward, so that the material discharge channel 321 is gradually opened. It can be understood that the longer the distance that the push block portion 422 slides toward the side close to the opening and closing member 41, the longer the distance that the opening and closing member 41 slides out of the material discharge channel 321, and the larger the opening of the material discharge channel 321, so that the opening size of the material discharge channel 321 can be adjusted by controlling the sliding distance of the drive rod 131 and the push rod 42.

[0067] like Figure 2 and Figure 6 As shown, in one embodiment, the driving assembly 13 further includes a motor 132 and a gear 133 disposed at the output end of the motor 132, and a rack 1311 meshing with the gear 133 is disposed at one end of the driving rod 131 away from the first coupler 14. The motor 132 can drive the gear 133 to rotate, and since the gear 133 meshes with the rack 1311 of the driving rod 131, the driving rod 131 can slide relative to the gear 133, so as to push against the push rod 42 through the driving rod 131. The driving assembly 13 has a simple structure, is easy to assemble, and does not occupy too much space on the mounting base 12.

[0068] Specifically, the driving rod 131 includes a second rod body portion 1312 and an adapter portion 1313 connected to the second rod body portion 1312, the adapter portion 1313 is provided with a waist-shaped hole 13131, the rack 1311 is arranged on the inner wall of the long side of the waist-shaped hole 13131, and the gear 133 is located in the waist-shaped hole 13131. The driving rod 131 slides relative to the gear 133 along the extension direction of the long side of the waist-shaped hole 13131 through the waist-shaped hole 13131 of the adapter portion 1313, and the waist-shaped hole 13131 can limit the movement path of the driving rod 131, ensuring that the gear 133 and the rack 1311 can always be meshed, and preventing the driving rod 131 from deviating or moving too far, resulting in the gear 133 and the rack 1311 losing teeth.

[0069] The driving assembly 13 further includes a first seat body 134, which is provided with a guide groove 1341, and the adapter 1313 is slidably disposed in the guide groove 1341 along the extension direction of the guide groove 1341. The guide groove 1341 can also limit the movement path of the adapter 1313, ensuring that the driving rod 131 always slides along the same straight line and the movement stroke is not too large.

[0070] Of course, in other embodiments, the drive assembly 13 may also include a motor 132, a screw and a slider, the screw is provided at the output end of the motor 132, the slider is provided with a threaded hole, and is threadedly matched with the screw, and the drive rod 131 is connected to the slider. The motor 132 can drive the screw to rotate, so that the slider can slide relative to the screw, and the drive rod 131 slides with the slider. Alternatively, the drive assembly 13 can also be set as a solenoid valve, an electric push rod, or other structures that can drive the drive rod 131 to perform linear reciprocating motion, and the embodiment of the utility model is not specifically limited here.

[0071] The motor 132 of the driving component 13 and the like can be electrically connected to the control device so as to control the operation of the driving component 13 through the control device.

[0072] like Figure 11 to Figure 12 As shown, in one embodiment, the rice adding device 2 is further provided with a rice washing chamber 22 connected to the feeding port 21 and an air outlet channel 24 connected to the side wall of the rice washing chamber 22; a first air inlet channel 327 connected to the side wall of the feeding channel 321 is also provided in the pot cover 32; wherein the first air inlet channel 327 includes a first side wall 3272 connected to the feeding channel 321, and the first side wall 3272 is tangent to the inner wall of the feeding channel 321; the air outlet channel 24 includes a second side wall 241 connected to the rice washing chamber 22, and the second side wall 241 is tangent to the inner wall of the rice washing chamber 22.

[0073] During the rice washing process, the outside air is driven by a driving device such as a fan to enter the unloading channel 321 through the first air inlet channel 327. Since the first side wall 3272 is tangent to the inner wall of the unloading channel 321, the gas entering the unloading channel 321 from the first air inlet channel 327 can move along the inner wall of the unloading channel 321 and form a cyclone, and the cyclone gradually flows into the rice washing chamber 22 along the path a; the rice in the unloading channel 321 and the rice washing chamber 22 moves and rubs against each other under the drive of the cyclone, so that impurities such as dust on the surface of the rice are separated. , dust and other impurities in the rice washing chamber 22 flow to the air outlet channel 24 together with the gas, and the rice remains in the rice washing chamber 22; because the second side wall 241 is tangent to the inner wall of the rice washing chamber 22, the cyclone moving along the inner wall of the rice washing chamber 22 can flow to the air outlet channel 24 along the tangent direction; the cyclone can cover the entire feeding channel 321 and the rice washing chamber 22, and also make the gas flow more smoothly in the first air inlet channel 327, the feeding channel 321, the rice washing chamber 22 and the air outlet channel 24, so as to ensure the rice washing effect. In addition, by adopting the cyclone rice washing method, some larger impurities in the rice can also be removed, and the water-soluble nutrients in the rice will not be lost, so that clean and nutritious rice can be cooked.

[0074] Among them, the first air inlet channel 327 and the air outlet channel 24 can be regular or irregular shapes such as circular and rectangular in cross-section perpendicular to the fluid flow direction. The first side wall 3272 can be any position in the first air inlet channel 327, and the first side wall 3272 can be a plane or a curved surface. When the first side wall 3272 is a curved surface, the section of the first side wall 3272 coincides with the inner wall of the feeding channel 321. Similarly, the air outlet channel 24 can be any position in the rice washing chamber 22, and the second side wall 241 can be a plane or a curved surface. When the second side wall 241 is a curved surface, the section of the second side wall 241 coincides with the inner wall of the rice washing chamber 22.

[0075] Of course, in other embodiments, it can also be configured so that only the first side wall 3272 is tangent to the inner wall of the feeding channel 321, or only the second side wall 241 is tangent to the inner wall of the rice washing chamber 22 according to the internal structure and size of the rice cooker.

[0076] like Figure 11 to Figure 12As shown, the cooking device 3 further includes an air inlet grid 38 disposed in the first air inlet channel 327, and the rice adding device 2 further includes an air outlet grid 23 disposed in the air outlet channel 24. The air inlet grid 38 can prevent air or impurities with a large volume in the first air inlet channel 327 from entering the material discharge channel 321 and affecting the rice washing effect, and can also prevent the rice in the material discharge channel 321 from entering the first air inlet channel 327. The air outlet grid 23 can prevent the rice in the rice washing chamber 22 from entering the air outlet channel 24. Preferably, the air inlet grille 38 is arranged at one end of the first air inlet channel 327 connected to the unloading channel 321, and the side of the air inlet grille 38 facing the unloading channel 321 is flush with the inner wall surface of the unloading channel 321, so that the cyclone flow in the unloading channel 321 is smoother; the air outlet grille 23 is arranged at one end of the air outlet channel 24 connected to the rice washing chamber 22, and the side of the air outlet grille 23 facing the rice washing chamber 22 is flush with the inner wall surface of the rice washing chamber 22, so that the cyclone flow in the rice washing chamber 22 is smoother.

[0077] Of course, in other embodiments, the air inlet grid 38 may be provided only in the first air inlet channel 327, or the air outlet grid 23 may be provided only in the air outlet channel 24, according to the internal structure and size of the electric rice cooker. Alternatively, a filter or other structure that can pass air but cannot pass rice may be provided in the first air inlet channel 327 and the air outlet channel 24, and the embodiment of the utility model is not specifically limited here.

[0078] It should be noted that "the first side wall 3272 is tangent to the inner wall of the material discharge channel 321" refers to the state that the first side wall 3272 is roughly tangent to the inner wall of the material discharge channel 321. It can be understood that when the air inlet grille 38 is arranged at the end where the first air inlet channel 327 is connected to the material discharge channel 321, due to factors such as the certain thickness of the air inlet grille 38 and the existence of processing errors, it may cause the first side wall 3272 to need to have a certain distance from the cross section of the material discharge channel 321. Therefore, when the distance between the first side wall 3272 and the cross section of the material discharge channel 321 is less than or equal to 5mm, it is defined as the state that the first side wall 3272 is tangent to the inner wall of the material discharge channel 321, and preferably, the distance between the first side wall 3272 and the cross section of the material discharge channel 321 is 0. Similarly, "the second side wall 241 is tangent to the inner wall of the rice washing chamber 22" refers to the state that the second side wall 241 is roughly tangent to the inner wall of the rice washing chamber 22. It can be understood that when the air outlet grid 23 is arranged at one end of the air outlet channel 24 connected to the rice washing chamber 22, since the air outlet grid 23 has a certain thickness, it may cause the second side wall 241 to need to have a certain distance from the cross-section of the rice washing chamber 22. Therefore, when the distance between the second side wall 241 and the cross-section of the rice washing chamber 22 is less than or equal to 5mm, it is defined as the state that the second side wall 241 is tangent to the inner wall of the rice washing chamber 22, and preferably, the distance between the second side wall 241 and the cross-section of the rice washing chamber 22 is 0.

[0079] like Figure 11 to Figure 12 As shown, at least during the rice washing process, the projection of the rice washing chamber 22 on the horizontal plane coincides with the projection of the material discharge channel 321 on the horizontal plane, so that the rice washing chamber 22 and the material discharge channel 321 form a whole, so that the cyclone flow in the rice washing chamber 22 and the material discharge channel 321 is smoother, further improving the rice washing effect.

[0080] like Fig.12 As shown, the first air inlet channel 327 has a fifth port 3273 connected to the material discharge channel 321, and along the circumference of the material discharge channel 321, the central angle β of the fifth port 3273 on the side wall of the material discharge channel 321 is ≤90°; the air outlet channel 24 has a sixth port 242 connected to the rice washing chamber 22, and along the circumference of the rice washing chamber 22, the central angle γ of the sixth port 242 on the side wall of the rice washing chamber 22 is ≤90°. That is to say, when the inner diameter of the material discharge channel 321 is R, the vertical distance between the end of the fifth port 3273 away from the first side wall 3272 and the first side wall 3272 is L1, satisfying L1≤R; similarly, when the inner diameter of the rice washing chamber 22 is R, the vertical distance between the end of the sixth port 242 away from the second side wall 241 and the second side wall 241 is L2, satisfying L2≤R. Such arrangement enables the gas flowing from the first air inlet channel 327 to the lower material channel 321 to be closer to the inner wall of the lower material channel 321 so as to form a cyclone in the lower material channel 321, and also enables the cyclone in the rice washing chamber 22 to flow more smoothly to the air outlet channel 24.

[0081] like Fig.12 As shown, in the illustrated embodiment, the flow direction of the fluid in the first air inlet channel 327 is parallel to and opposite to the flow direction of the fluid in the air outlet channel 24. The first air inlet channel 327 and the air outlet channel 24 are located on the same side of the feeding channel 321 and the rice washing chamber 22, so that the internal structure of the shell 11 is more regular, so as to facilitate the processing and assembly of the electric rice cooker. Of course, in other embodiments, the flow direction of the fluid in the first air inlet channel 327 and the flow direction of the fluid in the air outlet channel 24 can also be set to be at an angle to each other according to the internal structure and size of the electric rice cooker, and the embodiment of the utility model is not specifically limited here.

[0082] like Figure 1 and Fig.11 As shown, further, the rice adding device 2 can also include a dust box 25 connected to one end of the air outlet channel 24 away from the rice washing chamber 22, and a filter is provided in the dust box 25 to filter and collect impurities such as dust in the gas discharged from the air outlet channel 24.

[0083] like Figures 6 to 8As shown, the main body 1 also includes a water inlet pipe 15, and the first coupler 14 is provided with a first interface 141 communicating with the water inlet pipe 15; the pot cover 32 is also provided with a water inlet channel 322 communicating with the pot body 31, and the second coupler 33 is provided with a second interface 331 communicating with the water inlet channel 322; when the first coupler 14 is coupled with the second coupler 33, the first interface 141 is communicated with the second interface 331. When the second coupler 33 is coupled with the first coupler 14, the water inlet pipe 15 is communicated with the water inlet channel 322 through the first interface 141 of the first coupler 14 and the second interface 331 of the second coupler 33. One end of the water inlet pipe 15 away from the first coupler 14 can be communicated with a water tank (not shown) in the main body 1 or an external water source. When water needs to be added to the pot body 31, water from the water tank or external water source is driven to flow into the pot body 31 along the path b shown in the figure through the water inlet pipe 15, the first interface 141, the second interface 331 and the water inlet channel 322 in sequence, and the rice in the rice adding device 2 can fall into the pot body 31 through the discharge port 21 and the discharge channel 321 in sequence. When the first coupler 14 and the second coupler 33 are disengaged, the water inlet pipe 15 is disconnected from the water inlet channel 322. The water inlet pipe 15 and the water inlet channel 322 are connected through the coupling of the first coupler 14 and the second coupler 33, and the structure is simple and convenient for production and processing.

[0084] When the first coupler 14 is coupled to the second coupler 33 , the first interface 141 is sealed and connected to the second interface 331 , so as to prevent water leakage in the water inlet pipe 15 or the water inlet channel 322 .

[0085] like Figures 6 to 8 As shown, the pot cover 32 also has a water inlet connector 329 with one end connected to the water inlet channel 322 , and the other end of the water inlet connector 329 is exposed from the pot cover 32 and connected to the pot body 31 .

[0086] like Figure 6 and Fig.10As shown, in one embodiment, the embedded electric rice cooker further includes an anti-overflow device 5 and a temperature measuring device 6. The anti-overflow device 5 is arranged on the pot cover 32 and includes a conductive air outlet pipe 51, one end of which extends out of the pot cover 32 toward the pot body 31; the temperature measuring device 6 is arranged on the pot cover 32 and includes a temperature measuring element 61 arranged at intervals from the air outlet pipe 51, one end of which extends out of the pot cover 32 toward the pot body 31; the air outlet pipe 51 and the temperature measuring element 61 are both electrically connected to the second coupler 33 through a wire. When the second coupler 33 is coupled with the first coupler 14, the air outlet pipe 51 and the temperature measuring element 61 are both electrically connected to the control device through the second coupler 33 and the first coupler 14. During the cooking process, the temperature measuring element 61 is used to detect the temperature in the pot body 31, so that the control device can adjust the heating power and heating time of the heating element, etc. The steam generated in the pot body 31 can be discharged from the pot body 31 through the air outlet pipe 51 to avoid excessive air pressure in the pot body 31. When the soup in the pot body 31 boils, foam will be generated on the water surface. When the foam rises and contacts the air outlet pipe 51 and the temperature measuring element 61 at the same time, the air outlet pipe 51 and the temperature measuring element 61 will be turned on. After the control device detects that the air outlet pipe 51 and the temperature measuring element 61 are turned on, it controls the heating element to stop working or reduce the heating power of the heating element to prevent the foam from blocking the air outlet pipe 51 or overflowing from the air outlet pipe 51 and affecting the normal use of the electric rice cooker, thereby achieving the anti-overflow effect of the electric rice cooker. When the first coupler 14 and the second coupler 33 are disengaged, the air outlet pipe 51 and the temperature measuring element 61 are disconnected from the control device.

[0087] Of course, in other embodiments, for example, when the control device is directly disposed on the pot cover 32, the air outlet pipe 51 and the temperature measuring element 61 may also be directly electrically connected to the control device via wires.

[0088] like Figure 7 and Fig.10 As shown, the pot cover 32 is provided with a first air outlet channel 323, and the air outlet pipe 51 is detachably arranged in the first air outlet channel 323. So that the user can disassemble and clean the air outlet pipe 51. Specifically, the overflow prevention device 5 also includes a first fixing member 55 and a sixth sealing member 56. The first fixing member 55 is used to fix the air outlet pipe 51 to the pot cover 32 to ensure the reliability of the air outlet pipe 51 and prevent the air outlet pipe 51 from falling off. The sixth sealing member 56 can be arranged between the first fixing member 55 and the pot cover 32, and between the first fixing member 55 and the air outlet pipe 51, so as to prevent the gas in the pot body 31 from entering the assembly cavity 328 of the pot cover 32 through the gap between the first fixing member 55, the pot cover 32 and the air outlet pipe 51.

[0089] like Figure 6 and Fig.10As shown, in one embodiment, the overflow prevention device 5 further includes a guide rod 52 in contact with the outer wall of the air outlet pipe 51, and the air outlet pipe 51 is electrically connected to the control device through the guide rod 52. When the air outlet pipe 51 is installed in the first air outlet channel 323, the guide rod 52 is in contact with the outer wall of the air outlet pipe 51, and the guide rod 52 is electrically connected to the second coupler 33 through a wire. When the second coupler 33 is coupled with the first coupler 14, the air outlet pipe 51 is electrically connected to the control device through the guide rod 52, the second coupler 33 and the first coupler 14. As a result, there is no need to directly connect the wire to the air outlet pipe 51, simplifying the steps of disassembling and assembling the air outlet pipe 51, and facilitating user operation.

[0090] The guide rod 52 is disposed in the assembly cavity 328 and can extend into the first air outlet channel 323. Thus, the guide rod 52 can be prevented from being exposed, and the appearance of the pot cover 32 is ensured to be neat.

[0091] Of course, in other embodiments, for example, when the control device is directly disposed on the pot cover 32, the guide rod 52 may also be directly electrically connected to the control device via a wire; or, the air outlet pipe 51 may also be connected to the second coupler 33 or the control device via a wire.

[0092] like Figure 6 , Figure 7 and Fig.10 As shown, the guide rod 52 is slidably arranged on the pot cover 32, and one of the outer wall of the air outlet pipe 51 and the guide rod 52 is provided with a limiting groove 511, and the other is provided with a limiting portion 521 that can be plugged and matched with the limiting groove 511. When installing the air outlet pipe 51, first control the guide rod 52 to slide toward the side away from the air outlet pipe 51, and after the air outlet pipe 51 is installed in place, control the guide rod 52 to slide toward the side close to the air outlet pipe 51, so that the limiting portion 521 is inserted into the limiting groove 511, so that the air outlet pipe 51 can be limited, and it is also convenient for the user to align the air outlet pipe 51 when installing the air outlet pipe 51, so as to avoid the air outlet pipe 51 protruding too much from the pot cover 32 and affecting the normal operation of the electric rice cooker. Similarly, when disassembling the air outlet pipe 51, first control the guide rod 52 to slide toward the side away from the air outlet pipe 51, so that the limiting portion 521 is out of the limiting groove 511, and then the air outlet pipe 51 is pulled out of the first air outlet channel 323.

[0093] Preferably, the limiting groove 511 is provided on the outer wall of the air outlet pipe 51 and is provided as an annular groove, and the limiting portion 521 is provided at one end of the guide rod 52 facing the air outlet pipe 51. The limiting portion 521 can be plugged and matched with any position of the annular groove, so that there is no restriction on the installation angle of the air outlet pipe 51, which makes it more convenient for users to install the air outlet pipe 51.

[0094] like Figure 6As shown, the overflow prevention device 5 also includes a second seat body 53 and a second elastic member 54. The second seat body 53 is arranged in the assembly cavity 328 of the pot cover 32. The guide rod 52 is arranged in the second seat body 53 and can slide close to or away from the air outlet pipe 51. The second elastic member 54 is arranged between the guide rod 52 and the second seat body 53. When the guide rod 52 slides away from the air outlet pipe 51, the second elastic member 54 is compressed. When the air outlet pipe 51 is installed, the outer wall of the air outlet pipe 51 can push against the guide rod 52, so that the guide rod 52 slides on the second seat body 53 toward the side away from the air outlet pipe 51, and the second elastic member 54 is compressed. When the limiting portion 521 is aligned with the limiting groove 511, it means that the air outlet pipe 51 is installed in place. The guide rod 52 can slide toward the side close to the air outlet pipe 51 under the action of the second elastic member 54, so that the limiting portion 521 is inserted into the limiting groove 511, so that the user does not need to manually control the guide rod 52, simplifying the installation steps of the air outlet pipe 51. Of course, when the limiting portion 521 is plugged into the limiting groove 511, the second elastic member 54 can also be in a compressed state to improve the reliability of the matching between the limiting portion 521 and the limiting groove 511, thereby improving the reliability of the air outlet pipe 51. The second elastic member 54 can be configured as a compression spring and sleeved on the guide rod 52 to limit the deformation direction of the compression spring.

[0095] like Figure 7 and Fig.10 As shown, the temperature measuring member 61 can also be detachably connected to the pot cover 32, so that the user can replace or repair the temperature measuring member 61. The temperature measuring device 6 also includes a seventh sealing member 62 disposed between the temperature measuring member 61 and the pot cover 32 to prevent the gas in the pot body 31 from entering the assembly cavity 328 of the pot cover 32 through the gap between the temperature measuring member 61 and the pot cover 32.

[0096] like Figure 1 , Figure 2 and Figure 7 As shown, in one embodiment, the top seat 16 includes a second inclined surface 161 facing the pot cover 32, and the second inclined surface 161 gradually tilts upward from the inside of the housing 11 to the opening 111, and the pot cover 32 includes a third inclined surface 326 facing the top seat 16 and capable of being fitted with the second inclined surface 161. When the cooking device 3 is fully pushed into the housing 11, the second inclined surface 161 fits with the third inclined surface 326, and the top seat 16 can press the pot cover 32, thereby ensuring the reliability of the pot cover 32 during the cooking process. When the cooking device 3 is pulled out of the housing 11, the distance between the second inclined surface 161 and the third inclined surface 326 gradually increases, and the top seat 16 and the pot cover 32 will not rub against each other, so that the user can smoothly pull the cooking device 3 out of the housing 11 or push the cooking device 3 into the housing 11 without getting stuck. In addition, when pulling out the cooking device 3, it is not necessary to control the top seat 16 to open and close in the housing 11, thereby simplifying the operation steps.

[0097] Specifically, the angle α between the second inclined surface 161 and the horizontal plane satisfies 3°≤α≤10°. It can be understood that the angle between the third inclined surface 326 and the horizontal plane is the same as the angle α between the second inclined surface 161 and the horizontal plane, that is, it satisfies 3°≤α≤10°. Among them, α can be any value within the range of 3°≤α≤10°, such as 3°, 4°, 5°...9°, 10°, etc. α≥3° to ensure that the second inclined surface 161 and the third inclined surface 326 do not rub against each other when the cooking device 3 is pulled out of the shell 11 or pushed into the shell 11. α≤10° to avoid the inclination angles of the second inclined surface 161 and the third inclined surface 326 being too large to increase the height dimensions of the top seat 16 and the pot cover 32, thereby avoiding increasing the overall volume of the rice cooker.

[0098] Of course, in other embodiments, the contact surface between the top seat 16 and the pot cover 32 may also be parallel to the horizontal plane, as long as the reliability of the pot cover 32 during the cooking process is guaranteed and the cooking device 3 can be pulled out of the shell 11.

[0099] like Figure 7 and Fig.10 As shown, in one embodiment, the first gas outlet channel 323 has a first port 3231 opened on the third inclined surface 326; the top seat 16 is provided with a second gas outlet channel 162, the second gas outlet channel 162 has a second port 1621 opened on the second inclined surface 161, the second port 1621 is arranged corresponding to the first port 3231, and the end of the second gas outlet channel 162 away from the second port 1621 is connected to the outside. When the cooking device 3 is fully pushed into the housing 11, the first port 3231 is connected to the second port 1621, and the gas generated in the pot body 31 can be discharged from the electric rice cooker through the gas outlet pipe 51, the first port 3231, the second port 1621 and the second gas outlet channel 162 in sequence along the path c shown in the figure. The second inclined surface 161 and the third inclined surface 326 enable the first port 3231 to be closely connected with the second port 1621 , thereby preventing the gas in the gas outlet pipe 51 and the second gas outlet channel 162 from leaking into the main body 1 through the gap between the first port 3231 and the second port 1621 .

[0100] Of course, in other embodiments, the end of the first gas outlet channel 323 away from the pot body 31 can also be directly connected to the outside, as long as the gas generated in the pot body 31 can be discharged to the outside, and the embodiment of the utility model does not make specific restrictions here.

[0101] like Fig.10As shown, in one embodiment, the cooking device 3 further includes a first sealing member 361 disposed at the periphery of the first port 3231 and the periphery of the second port 1621. When the cooking device 3 is fully pushed into the housing 11, the second inclined surface 161 and the third inclined surface 326 can press the first sealing member 361, thereby further improving the sealing between the first port 3231 and the second port 1621.

[0102] Of course, in other embodiments, the first seal 361 may be provided only on the periphery of the first port 3231 or only on the periphery of the second port 1621. As long as the sealing performance when the first port 3231 and the second port 1621 are connected can be ensured and the gas in the first air outlet channel 323 and the second air outlet channel 162 will not leak into the main body 1, the embodiments of the utility model are not specifically limited here.

[0103] like Figure 2 , Figure 3 and Figure 7 As shown, the feed opening 21 of the rice adding device 2 is opened on the second inclined surface 161, and the feed channel 321 has a feed opening 3211 opened on the third inclined surface 326, and the feed opening 3211 is arranged corresponding to the feed opening 21. When the cooking device 3 is fully pushed into the shell 11, the second inclined surface 161 and the third inclined surface 326 enable the feed opening 21 and the feed opening 3211 to be closely connected, so as to prevent the rice in the rice washing cavity 22 and the feed channel 321 from leaking into the main body 1 through the gap between the feed opening 21 and the feed opening 3211, and also to prevent the gas in the rice washing cavity 22 and the feed channel 321 from leaking into the main body 1 through the gap between the feed opening 21 and the feed opening 3211 during the rice washing process.

[0104] like Figure 2 and Fig.10 As shown, in one embodiment, the cooking device 3 further includes a second sealing member 362 disposed at the periphery of the feed inlet 3211 and the periphery of the feed outlet 21. When the cooking device 3 is fully pushed into the housing 11, the second inclined surface 161 and the third inclined surface 326 can compress the second sealing member 362, thereby further improving the sealing between the feed inlet 3211 and the feed outlet 21.

[0105] Of course, in other embodiments, the second sealing member 362 may be provided only on the periphery of the feed port 3211 or only on the periphery of the discharge port 21.

The size of the air inlet 371 can be made smaller to match the size of the fourth port 1631, and the inner size of the third port 3271 and the first air inlet channel 327 can be made larger, so that the user can remove the air inlet cover 37 and insert the cleaning tool into the third port 3271 to clean the first air inlet channel 327, so as to avoid the accumulation of dust or impurities in the first air inlet channel 327 after long-term use, which may affect the rice washing effect.

[0111] like Fig. 9 As shown, the cooking device 3 further includes a fourth sealing member 364 disposed between the air inlet cover 37 and the inner wall of the third port 3271. The inner wall of the air inlet cover 37 and the third port 3271 can compress the fourth sealing member 364, thereby further improving the sealing between the air inlet cover 37 and the inner wall of the third port 3271, and preventing the greasy gas in the main body 1 from entering the first air inlet channel 327 and the second air inlet channel 163 through the gap between the air inlet cover 37 and the inner wall of the third port 3271, thereby affecting the rice washing effect.
