Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and more particularly, to a cooking appliance. Background Art

[0002] An electric pressure cooker is a commonly used cooking appliance. After the electric pressure cooker finishes cooking, the temperature of the pot body is relatively high and the pressure is relatively large, and the user needs to wait for a period of time before opening the lid to eat. However, the above waiting time is often relatively long, thus resulting in a poor user experience.

[0003] In the prior art, after the electric pressure cooker finishes cooking, a cooling medium is usually introduced into the pot body to directly contact the outer wall surface of the inner pot to cool the pot body and quickly reduce the pressure. However, when the user picks up the inner pot, the liquid cooling medium located in the pot body can be seen, which causes the user to have concerns about the safety of using the electric pressure cooker, reducing the user's favorable impression of the use experience. In addition, the cooling medium will also adhere to the outer wall surface of the inner pot, making the outer wall surface of the inner pot wet, and when the user picks up the inner pot, it is easy for the cooling medium to drip randomly, also reducing the user's favorable impression of the use experience of the electric pressure cooker. Summary of the Invention

[0004] The main object of the present invention is to provide a cooking appliance to solve the problem that the cooling medium used for cooling the inner pot of the electric pressure cooker in the prior art cannot be effectively sealed, resulting in a poor user experience of the electric pressure cooker.

[0005] To achieve the above object, the present invention provides a cooking appliance, including: a pot body, the pot body including an inner pot; a cooling cavity, the cooling cavity being located in the pot body, and part of the cavity wall enclosing the cooling cavity having a separation position separated from the inner pot and a fitting position fitting with the outer wall surface of the inner pot. When there is a cooling medium in the cooling cavity and when part of the cavity wall is in the fitting position, part of the cavity wall fits with the inner pot to cool the inner pot.

[0006] By applying the technical solution of the present invention, since a cooling cavity is provided in the pot body, part of the cavity wall enclosing the cooling cavity has a separation position separated from the inner pot and a fitting position fitting with the outer wall surface of the inner pot. When there is a cooling medium in the cooling cavity and when part of the cavity wall is in the fitting position, part of the cavity wall fits with the inner pot to cool the inner pot.

[0007] In this way, when part of the cavity wall enclosing the cooling cavity is in contact with the outer wall surface of the inner pot, heat exchange occurs between the inner pot and the cooling cavity. The heat in the inner pot passes through the pot wall of the inner pot and then through the cavity wall enclosing the cooling cavity and in contact with the outer wall surface of the inner pot, and is finally absorbed by the cooling medium. This process occurs rapidly after the cooking appliance finishes cooking the food, thus achieving the effect of quickly reducing the temperature and pressure of the inner pot, and the user can immediately open the pot lid to taste delicious food in a short time. When part of the cavity wall enclosing the cooling cavity is separated from the inner pot, the inner pot of the cooking appliance is normally heated to cook the food. During this process, the cavity wall of the cooling cavity does not contact the inner pot, thereby preventing the heat in the inner pot from being lost by heat transfer, and then achieving the heat preservation effect of the inner pot and improving the cooking efficiency of the cooking appliance.

[0008] Further, the pot body further includes a heat preservation cover and a heating device. The inner pot is arranged inside the heat preservation cover, and the cavity wall enclosing the cooling cavity is movably arranged on the heat preservation cover and / or the heating device to drive the cooling cavity to move.

[0010] Further, the partition part is a flexible partition part. The flexible partition part covers the heating device to enclose the cooling cavity with the heating device. When the cooling medium is introduced into the cooling cavity, the flexible partition part moves from the separation position to the fitting position under the pressure of the cooling medium.

[0011] Further, the partition part is a flexible partition part. The flexible partition part is fixed on the heat preservation cover to enclose the cooling cavity with part of the heat preservation cover and the heating device. When the cooling medium is introduced into the cooling cavity, the flexible partition part moves from the separation position to the fitting position under the pressure of the cooling medium.

[0012] Further, the heating device is arranged below the heat preservation cover. The heating device includes a heating plate and a support cylinder part connected to the heating plate and extending upward. The flexible partition part is clamped between the heat preservation cover and the support cylinder part.

[0013] Further, the flexible partition part includes a diaphragm body. The diaphragm body includes a contact part and a corrugated buffer part. The corrugated buffer part is connected to the contact part to prevent the diaphragm body from being damaged.

[0014] Further, the thickness t of the corrugated buffer part is less than or equal to the thickness T of the contact part.

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0037] In order to solve the problem that the diaphragm of the electric pressure cooker in the prior art cannot be stably installed in the shell of the pot body, resulting in poor isolation effect of the diaphragm on the cooling medium, the present invention provides a cooking utensil. It should be noted that the cooking utensil involved in the present application includes an electric pressure cooker and an electric rice cooker, but is not limited to the two.

[0038] like Figure 1 and Figure 2 As shown, the cooking appliance includes a pot body 100 and a cooling cavity 12, the pot body 100 includes an inner pot 130, the cooling cavity 12 is located in the pot body 100, and a portion of the cavity wall surrounding the cooling cavity 12 has a separation position separated from the inner pot 130 and a fitting position fitted with the outer wall surface of the inner pot 130. When there is a cooling medium in the cooling cavity 12 and when a portion of the cavity wall is in the fitting position, the portion of the cavity wall fits with the inner pot 130 to cool the inner pot 130.

[0039] Since a cooling cavity 12 is provided in the pot body 100, part of the cavity wall surrounding the cooling cavity 12 has a separation position separated from the inner pot 130 and a fitting position fitted with the outer wall surface of the inner pot 130. When there is a cooling medium in the cooling cavity 12 and when part of the cavity wall is in the fitting position, part of the cavity wall fits with the inner pot to cool the inner pot 130.

[0040] In this way, when part of the cavity wall forming the cooling cavity 12 is in contact with the outer wall surface of the inner pot 130, heat exchange occurs between the inner pot 130 and the cooling cavity 12, and the heat in the inner pot 130 passes through the pot wall of the inner pot and then passes through the cavity wall forming the cooling cavity 12 and in contact with the outer wall surface of the inner pot 130, and is finally absorbed by the cooling medium. This process occurs quickly after the cooking utensil finishes cooking the food, thereby achieving the effect of quickly cooling and reducing the pressure of the inner pot 130, and the user can immediately open the pot lid to taste delicious food in a short time; and when part of the cavity wall forming the cooling cavity 12 is separated from the inner pot 130, the inner pot 130 of the cooking utensil is heated normally to achieve the purpose of cooking food. In this process, the cavity wall of the cooling cavity 12 does not contact the inner pot 130, thereby preventing the heat in the inner pot 130 from being lost through heat transfer, thereby achieving the insulation effect of the inner pot 130 and improving the cooking efficiency of the cooking utensil.

[0041] like Figures 1 to 3As shown in the figure, the cooking appliance includes a pot body 100 and a partition. Among them, the pot body 100 includes a heat preservation cover 120, an inner pot 130, and a heating device 140. The inner pot 130 is used to hold the food to be cooked. The heating device 140 is arranged below the heat preservation cover 120. The partition is clamped between the heat preservation cover 120 and the heating device 140. The partition and the heating device 140 together enclose a cooling cavity 12. The cooling cavity 12 is used to inject a cooling medium. The inner pot 130 is located on the side of the partition away from the cooling cavity 12. When the cooling medium is injected into the cooling cavity 12, the inner pot 130 is cooled.

[0042] Since the cooking appliance includes a partition clamped between the heat preservation cover 120 and the heating device 140, the partition and the heating device 140 together enclose a cooling cavity 12. The cooling cavity 12 is used to inject a cooling medium. The inner pot 130 is located on the side of the partition away from the cooling cavity 12. When the cooling medium is injected into the cooling cavity 12, the inner pot 130 is cooled. In this way, the setting of the partition plays a role in restricting the movement of the cooling medium, enabling the cooling medium to only move within the cooling cavity 12, avoiding direct contact between the cooling medium and the inner pot 130, and preventing a certain amount of refrigerant from being carried out when the user takes out the inner pot 130, which makes the outer wall surface of the inner pot 130 slippery, thereby improving the user's favorable impression of the use experience of the cooking appliance.

[0043] In the illustrated embodiment of the present application, the partition is a flexible partition 200. The flexible partition 200 covers the heating device 140 to enclose the cooling cavity 12 with the heating device 140. When the cooling medium is introduced into the cooling cavity 12, the flexible partition 200 moves from the separated position to the fitting position under the pressure of the cooling medium. In this way, when the cooling medium fills the cooling cavity 12 and continues to be incorporated into the cooling cavity 12, the flexible partition 200 can deform and move under the pressure of the cooling medium. The surface tension of the flexible partition 200 continuously increases, and the surface area continuously increases until it contacts the outer wall surface of the inner pot 130 to achieve the purpose of quickly cooling and depressurizing the inner pot 130.

[0044] In an optional embodiment not illustrated in the present application, the partition is a flexible partition 200. The flexible partition 200 is fixed on the heat preservation cover 120 to jointly enclose the cooling cavity 12 with a part of the heat preservation cover 120 and the heating device 140. When the cooling medium is introduced into the cooling cavity 12, the flexible partition 200 moves from the separated position to the fitting position under the pressure of the cooling medium. In this implementation, the outer periphery of the flexible partition 200 is connected to the inner wall surface of the heat preservation cover 120.

[0045] Specifically, in the illustrated embodiment of the present application, the separating part is a flexible separating part 200. The flexible separating part 200 has a fitting position that fits the outer wall surface of the inner pot 130 and a separating position separated from the inner pot 130. When a cooling medium is introduced into the cooling cavity 12, the flexible separating part 200 moves from the separating position to the fitting position under the pressure of the cooling medium. When no cooling medium is introduced into the cooling cavity 12, the flexible separating part 200 is in the separating position under the natural stress state. In this way, when the cooling medium fills the cooling cavity 12 and continues to be introduced into the cooling cavity 12, the flexible separating part 200 can deform and move under the pressure of the cooling medium, the surface tension of the flexible separating part 200 continuously increases, and the surface area continuously increases until it contacts the outer wall surface of the inner pot 130 to achieve the purpose of quickly reducing the temperature and pressure of the inner pot 130.

[0046] Optionally, the flexible separating part 200 is in the shape of a thin film.

[0047] Preferably, the thickness of the flexible separating part 200 in the shape of a thin film is greater than 0 and less than or equal to 4 mm.

[0048] Optionally, the cooling medium is a liquid coolant.

[0049] Optionally, the flexible separating part 200 is made of heat-conducting silica gel. The flexible separating part 200 made of this material has strong high-temperature resistance, avoiding being damaged by the high-temperature outer wall surface of the inner pot 130. In addition, the flexible separating part 200 made of this material also has good heat transfer performance. When the flexible separating part 200 contacts the outer wall surface of the inner pot 130, heat and cold can be quickly exchanged through the flexible separating part 200 to achieve the purpose of quickly reducing the temperature and pressure of the inner pot 130. Moreover, the flexible separating part 200 made of this material also has strong elastic deformation ability, and can fully fit the outer wall surface of the inner pot 130 when the flexible separating part 200 is in the fitting position. Finally, the flexible separating part 200 made of this material also has good economy, which can reduce the overall cost of the cooking appliance.

[0050] In an optional embodiment not illustrated in the present application, the separating part is a rigid separating part, and the rigid separating part is arranged to fit the outer wall surface of the inner pot 130. In this way, the purpose of quickly reducing the temperature and pressure of the inner pot 130 can also be achieved, and the overall cost of the separating part can be effectively controlled.

[0051] In another optional embodiment not illustrated in the present application, considering that when the inner pot 130 of the cooking appliance is normally heated, to avoid the heat of the inner pot 130 being lost by heat transfer and prolonging the cooking time, the separating part is a rigid separating part, and the rigid separating part is arranged at an interval from the outer wall surface of the inner pot 130.

[0052] Optionally, in order to further reduce the overall cost of the partition, the rigid partition is made of sheet-shaped metal material.

[0053] As Figures 1 to 3 shown, the heating device 140 includes a heating plate 141 and a support cylinder portion 142 connected to the heating plate 141 and extending upward; the partition is clamped between the heat insulation cover 120 and the support cylinder portion 142. Among them, the support cylinder portion 142 and the heating plate 141 are of an integral structure or are detachably connected. The top annular surface of the support cylinder portion 142 and the bottom annular surface of the heat insulation cover 120 have equal areas to achieve a stable clamping effect on the partition.

[0054] As Figure 1 and Figure 2 shown, the heating device 140 is arranged below the heat insulation cover 120. The heating device 140 includes a heating plate 141 and a support cylinder portion 142 connected to the heating plate 141 and extending upward. The flexible partition 200 is clamped between the heat insulation cover 120 and the support cylinder portion 142. Among them, the support cylinder portion 142 and the heating plate 141 are of an integral structure or are detachably connected. The top annular surface of the support cylinder portion 142 and the bottom annular surface of the heat insulation cover 120 have equal areas to achieve a stable clamping effect on the partition.

[0055] In an optional embodiment not shown in the present application, the cavity wall surrounding the cooling cavity 12 is movably arranged on the pot body 100 to move between a fitting position where part of the cavity wall is in contact with the outer wall surface of the inner pot 130 and a separation position where it is separated from the inner pot 130.

[0056] In an optional embodiment not shown in the present application, the pot body 100 further includes a heat insulation cover 120 and a heating device 140. The inner pot 130 is arranged inside the heat insulation cover 120. The cavity wall surrounding the cooling cavity 12 is movably arranged on the heat insulation cover 120 and / or the heating device 140 to drive the cooling cavity 12 to move. This implementation method enables part of the cavity wall surrounding the cooling cavity 12 to move between a fitting position where it is in contact with the outer wall surface of the inner pot 130 and a separation position where it is separated from the inner pot 130 based on the principle of mechanical transmission.

[0057] It should be noted that the pot body 100 further includes a heat insulation cover 120, a heating device 140 and a partition. The partition and at least part of the heat insulation cover 120 enclose the cooling cavity 12, or the partition and at least part of the heating device 140 enclose the cooling cavity 12, or the partition and at least part of the heat insulation cover 120 and at least part of the heating device 140 jointly enclose the cooling cavity 12. Among them, the partition has a separation position and a fitting position. The partition is part of the cavity wall. That is to say, the part of the cavity wall that has a separation position separated from the inner pot 130 and a fitting position in contact with the inner pot 130 forms the partition.

[0058] The above describes three alternative forming methods of the cooling cavity 12 in the cooking appliance of the present application. That is to say, whether the partition is connected to the heat insulation cover 120 to enclose the cooling cavity 12 with at least a part of the heat insulation cover 120, or the partition is connected to the heating device 140 to enclose the cooling cavity 12 with at least a part of the heating device 140, or the partition is connected to both the heat insulation cover 120 and the heating device 140 to enclose the cooling cavity 12 with at least a part of both of them, all are alternative implementation manners that can achieve the cooling of the inner pot 130 in the present application. In the above three implementation manners, the partition has a separation position separated from the inner pot 130 and a fitting position fitting with the outer wall surface of the inner pot 130.

[0059] As Figure 4 shown, the cooking appliance further includes a liquid storage tank and a delivery pipeline 500. The liquid storage tank is arranged inside the pot body 100 and stores a cooling medium. Both ends of the delivery pipeline 500 are respectively communicated with the liquid storage tank and the cooling cavity 12, so that the cooling medium in the liquid storage tank enters the cooling cavity 12 through the delivery pipeline 500 to cool the inner pot 130. Among them, a water pump 600 is arranged on the delivery pipeline 500.

[0060] In this way, after the cooking of the cooking appliance is finished, the water pump 600 pumps the cooling medium into the cooling cavity 12, and the cooling cavity 12 cools the inner pot 130 and quickly reduces the pressure. After the cooling is finished, the cooling medium returns to the liquid storage tank through the delivery pipeline 500. The above structure greatly shortens the waiting time for opening the lid after cooking of the cooking appliance and improves the user experience of the product, and solves the problem that an electric pressure cooker needs to wait for a long time to open the lid after cooking.

[0061] As Figure 4 shown, the delivery pipeline 500 includes a liquid inlet pipeline 510 and a liquid outlet pipeline 520. Both ends of the liquid inlet pipeline 510 are respectively communicated with the liquid storage tank and the cooling cavity 12, and both ends of the liquid outlet pipeline 520 are respectively communicated with the liquid storage tank and the cooling cavity 12. The cooling medium in the liquid storage tank enters the cooling cavity 12 through the liquid inlet pipeline 510 to cool the inner pot 130. After the cooling is finished, the cooling medium returns to the liquid storage tank through the liquid outlet pipeline 520. Specifically, one end of the liquid inlet pipeline 510 is communicated with the liquid storage tank, and the other end of the liquid inlet pipeline 510 is communicated with the cooling cavity 12. Similarly, one end of the liquid outlet pipeline 520 is communicated with the liquid storage tank, and the other end of the liquid outlet pipeline 520 is communicated with the cooling cavity 12. The above structure can realize the circulation of the cooling medium between the cooling cavity 12 and the liquid storage tank.

[0062] It should be noted that, in order to ensure the efficiency of the cooling medium entering and leaving the cooling cavity 12, the opening of the liquid inlet pipeline 510 communicated with the cooling cavity 12 is on the support cylinder part 142 of the heating device 140, and the opening of the liquid outlet pipeline 520 communicated with the cooling cavity 12 is at the bottom of the heating plate 141 of the heating device 140.

[0063] As Figure 1 , Figure 2 , Figure 5 and Figures 9 to 11 shown, the cooking appliance includes a pot body 100 and a partition portion. The pot body 100 includes a housing 110, a heat preservation cover 120, and an inner pot 130 that are sequentially arranged from outside to inside. The inner pot 130 is used to hold the food to be cooked. The inner pot 130 is located on one side of the partition portion away from the cooling cavity 12. The pot body 100 further includes a heating device 140. The heating device 140 is arranged below the heat preservation cover 120. The partition portion is clamped between the heat preservation cover 120 and the heating device 140 and encloses a cooling cavity 12 with the heating device 140. The cooling cavity 12 is used to inject a cooling medium;

[0064] Wherein, the partition portion includes a diaphragm body 210 and a stop and limit structure 220. The stop and limit structure 220 is connected to the outer peripheral edge of the diaphragm body 210, and at least a part of the stop and limit structure 220 passes through an installation gap 13 formed between the heat preservation cover 120 and the heating device 140 from inside to outside and is hooked on the heating device 140 and / or the heat preservation cover 120.

[0065] Since the partition portion includes the stop and limit structure 220 connected to the outer peripheral edge of the diaphragm body 210 and at least a part of the stop and limit structure 220 passes through the installation gap 13 formed between the heat preservation cover 120 and the heating device 140 from inside to outside and is hooked on the heating device 140 and / or the heat preservation cover 120. In this way, the setting of the stop and limit structure 220 improves the stability of the partition portion clamped between the heat preservation cover 120 and the heating device 140. During the working process of the cooking appliance, the loosening phenomenon caused by excessive force at the connection between the partition portion and the heat preservation cover 120 and the heating device 140 is avoided, so that the cooling cavity 12 is in an effective sealing state, preventing the refrigerant from leaking from the cooling cavity 12 and contacting the inner pot 100, improving the isolation effect of the partition portion on the cooling medium, and ensuring the working stability of the cooking appliance.

[0066] As Figure 3 shown, the stop and limit structure 220 is annular, and the annular stop and limit structure 220 is continuously arranged around the outer peripheral edge of the diaphragm body 210. In the illustrated embodiment of the present application, the annular stop and limit structure 220 is continuously arranged around the outer peripheral edge of the diaphragm body 210. In this way, the stop and limit structure 220 serves as the entire circumferential edge of the partition portion, and the installation gap 13 is filled with the diaphragm body 210 and / or a part of the stop and limit structure 220, forming a surface-to-surface seal between the partition portion and the heating device 140. In this way, the sealing effect of the cooling cavity 12 can be effectively improved by using the self-structure of the partition portion, and the leakage of the cooling medium at the installation gap 13 is avoided.

[0067] Of course, in order to save the consumables for manufacturing the partition portion, the stop and limit structure 220 can also not be annular. In an embodiment not shown in the present application, there are a plurality of stop and limit structures 220, and the plurality of stop and limit structures 220 are arranged at intervals along the outer periphery of the diaphragm body 210. In this way, a plurality of support points are formed at the plurality of stop and limit structures 220, and the diaphragm body 210 can also be supported between the heat preservation cover 120 and the heating device 140 in a stretched manner, so that the diaphragm body 210 can play the role of quickly cooling the inner pot 130.

[0068] In the above-mentioned embodiment not shown, considering the sealing effect at the connection between the partition portion and the heat preservation cover 120 and the heating device 140, there are several alternative implementation manners:

[0069] First, the outer peripheral edge of the diaphragm body 210 is evenly pressed between the heat preservation cover 120 and the heating device 140, and the outer peripheral edge of the diaphragm body 210 is located within the installation gap 13. The stop and limit structure 220 is connected to the outer peripheral edge of the diaphragm body 210. A part of the stop and limit structure 220 is located within the installation gap 13, while another part of the stop and limit structure 220 extends out of the installation gap 13. In this case, although the installation gap 13 is not completely filled by the partition portion, at the connection between the heating device 140 and the partition portion, the diaphragm body 210 still performs a complete circumferential line seal, which also ensures the sealing effect among the heat preservation cover 120, the partition portion, and the heating device 140, and avoids the leakage of the cooling medium at the installation gap 13.

[0070] Second, as a preferred implementation manner, to better achieve the sealed connection between the partition portion and the heating device 140, the diaphragm body 210 completely fills the installation gap 13, and the stop and limit structure 220 is located outside the installation gap 13. In this way, a surface-to-surface seal is still formed between the diaphragm body 210 and the heating device 140.

[0071] Third, the diaphragm body 210 is located outside the installation gap 13. A part of the stop and limit structure 220 passes through the installation gap 13 from the inside to the outside, and another part of the stop and limit structure 220 extends out of the installation gap 13 and serves as the part hooked to the heat preservation cover 120 and / or the heating device 140. In this case, an external component needs to be used to achieve the connection and seal between the partition portion and the heating device 140, that is, to seal the cooling cavity 12 at the connection between the partition portion and the heating device 140. Here, sealant can be used for sealing, or a seal can be used to paste the opening part between the partition portion and the heating device 140. These methods all belong to the means that those skilled in the art can think of, and will not be listed one by one here. The effect achieved by the present application is to seal the cooling cavity 12 while ensuring that the partition portion is stably clamped between the heat preservation cover 120 and the heating device 140, and avoid the leakage of the cooling medium in the cooling cavity 12.

[0072] In the above-described embodiments not shown, as a preferred implementation, there are three stop and limit structures 220, and the three stop and limit structures 220 are equally spaced. In this way, by utilizing the principle of triangle stability, the diaphragm body 210 can be stably supported.

[0073] As Figure 5 and Figures 9 to 11 shown, the stop and limit structure 220 includes a clamping and limiting section 221 and a hooked stop section 222 connected in a direction away from the diaphragm body 210. Among them, the clamping and limiting section 221 is located at the installation gap 13, and the hooked stop section 222 is arranged at an angle with the clamping and limiting section 221. In this way, the clamping and limiting section 221 can be stably clamped by the heat insulation cover 120 and the heating device 140, and the upper and lower surfaces of the clamping and limiting section 221 are both subjected to the action of friction, preventing the stop and limit structure 220 from moving relative to the heat insulation cover 120 or the heating device 140 at the installation gap 13. In addition, the fact that the hooked stop section 222 is arranged at an angle with the clamping and limiting section 221 enables a stop end face to be formed on the surface of the hooked stop section 222 facing the diaphragm body 210, so that the hooked stop section 222 is hooked on the outer wall surface of the heat insulation cover 120 and / or the heating device 140, further improving the setting stability of the diaphragm body 210.

[0074] In order to facilitate the processing and manufacturing of the stop and limit structure 220, thereby reducing the overall cost of the partition part, improving the economy of the cooking appliance, and enhancing its market competitiveness, as Figures 9 to 11 shown, the hooked stop section 222 is perpendicular to the clamping and limiting section 221.

[0075] The stop and limit structure 220 has the following several optional structures.

[0076] As Figure 9 shown, the first end of the hooked stop section 222 is connected to the clamping and limiting section 221, and the second end of the hooked stop section 222 extends towards the side of the heating device 140.

[0077] As Figure 10 shown, the first end of the hooked stop section 222 is connected to the clamping and limiting section 221, and the second end of the hooked stop section 222 extends towards the side of the heat insulation cover 120.

[0078] As Figure 11 shown, the clamping and limiting section 221 is connected between the first end and the second end of the hooked stop section 222 so that the two ends of the hooked stop section 222 are respectively located on both sides of the installation gap 13.

[0079] For the above three structures of the stop and limit structure 220, the diaphragm body 210 can be radially limited through the hooked stop section 222 of the stop and limit structure 220.

[0080] As Figure 1 、 Figure 2 、 Figure 6 and Figures 9 to 11 shown, the flexible partition 200 includes a diaphragm body 210, and the diaphragm body 210 includes a contact portion 211 and a corrugated buffer portion 212. The corrugated buffer portion 212 is connected to the contact portion 211 to prevent damage to the diaphragm body 210.

[0081] Since the diaphragm body 210 includes a contact portion 211 and a corrugated buffer portion 212 connected to the contact portion 211, and the corrugated buffer portion 212 is the main part where deformation occurs, it can effectively drive the contact portion 211 to move, so that the contact portion 211 fits or separates from the outer wall surface of the inner pot 130, avoiding stress concentration and damage on the contact portion 211, extending the service life of the flexible partition 200, and ensuring the reliability of the deformation movement of the flexible partition 200, improving the use stability of the cooking appliance.

[0082] Optionally, the contact portion 211 and the corrugated buffer portion 212 are of an integral structure.

[0083] Optionally, the thickness t of the corrugated buffer portion 212 is less than or equal to the thickness T of the contact portion 211. In this way, it is more conducive to the corrugated buffer portion 212 deforming to drive the contact portion 211 to move.

[0084] Preferably, the thickness t of the corrugated buffer portion 212 is less than or equal to 1.5 mm, and the thickness T of the contact portion 211 is less than or equal to 4 mm.

[0085] As Figure 1 、 Figure 2 and Figure 7 shown, the diaphragm body 210 is annular, the contact portion 211 is a curved surface structure, and there are two corrugated buffer portions 212. The two corrugated buffer portions 212 are respectively located at the inner peripheral edge and the outer peripheral edge of the contact portion 211. The arrangement of the two corrugated buffer portions 212 can more effectively drive the contact portion 211 located between the two corrugated buffer portions 212 to deform and move, thus ensuring the working stability of the flexible partition 200.

[0086] Specifically, the corrugated buffer portion 212 located at the inner peripheral edge of the contact portion 211 is arranged at an angle with the contact portion 211, and / or the corrugated buffer portion 212 located at the outer peripheral edge of the contact portion 211 is V-shaped.

[0087] As Figures 1 to 3As shown, the diaphragm body 210 is annular. An avoidance hole 143 is provided on the heating device 140. The cooking appliance further includes a temperature sensing component 300 movably disposed at the avoidance hole 143. A sealing structure 400 is provided between the temperature sensing component 300 and the heating device 140. The inner peripheral edge of the diaphragm body 210 is connected to the sealing structure 400. The outer peripheral edge of the annular diaphragm body 210 is pressed between the heat preservation cover 120 and the heating device 140. Specifically, the avoidance hole 143 is provided in the middle of the bottom of the heating plate 141. The temperature sensing component 300 is used to measure the temperature inside the inner pot 130. When the inner pot 130 is placed in the heat preservation cover 120, the temperature sensing component 300 is pressed down by the inner pot 130. When the inner pot 130 is taken out, the temperature sensing component 300 resets under the action of the elastic member. The sealing structure 400 can prevent the coolant from flowing out of the gap between the temperature sensing component 300 and the avoidance hole 143. Preferably, the sealing structure 400 is a sealing ring.

[0088] Optionally, the sealing structure 400 and the flexible partition 200 are of an integral structure. In this way, it further avoids the coolant from flowing out of the gap between the temperature sensing component 300 and the avoidance hole 143 along the cooling cavity 12, and the sealing structure 400 and the flexible partition 200 can be formed by one-time processing and injection molding, which can effectively control the overall cost of the cooking appliance.

[0089] As Figure 1 、 Figure 2 、 Figure 5 and Figures 9 to 11 shown, the flexible partition 200 further includes a stop and limit structure 220 connected to the outer peripheral edge of the diaphragm body 210. The diaphragm body 210 is hung on the heating device 140 and / or the heat preservation cover 120 through the stop and limit structure 220.

[0090] Since the partition includes a stop and limit structure 220 connected to the outer peripheral edge of the diaphragm body 210 and at least a part of the stop and limit structure 220 passes through the installation gap 13 formed between the heat preservation cover 120 and the heating device 140 from inside to outside and is hung on the heating device 140 and / or the heat preservation cover 120. In this way, the setting of the stop and limit structure 220 improves the stability of the partition clamped between the heat preservation cover 120 and the heating device 140. During the operation of the cooking appliance, the loosening phenomenon caused by excessive force at the connection between the partition and the heat preservation cover 120 and the heating device 140 is avoided, so that the cooling cavity 12 is in an effective sealed state, preventing the refrigerant from leaking from the cooling cavity 12 and contacting the inner pot 130, improving the isolation effect of the partition on the cooling medium, and ensuring the working stability of the cooking appliance.

[0091] As Figure 3As shown in the figure, the cooking appliance includes a pot body 100, a partition portion, and a heat preservation cover 120. The pot body 100 includes the heat preservation cover 120 and a heating device 140 disposed below the heat preservation cover 120. The partition portion is clamped between the heat preservation cover 120 and the heating device 140 and encloses a cooling cavity 12 with the heating device 140. The cooling cavity 12 is used for injecting a cooling medium. A first connection structure 10 is provided on the outer wall surface of the heat preservation cover 120, and a second connection structure 20 is provided on the heating device 140. The first connection structure 10 cooperates with the second connection structure 20 to position and lock the heating device 140 and the heat preservation cover 120 and clamp the partition portion.

[0092] By providing the first connection structure 10 on the outer wall surface of the heat preservation cover 120 and the second connection structure 20 on the heating device 140, the first connection structure 10 cooperates with the second connection structure 20 to position and lock the heating device 140 and the heat preservation cover 120 and clamp the partition portion. In this way, not only the connection stability between the heat preservation cover 120 and the heating device 140 is enhanced, enabling the two to reliably clamp the partition portion, ensuring effective sealing of the cooling cavity 12 at the periphery of the partition portion to prevent leakage of the cooling medium and improving the use stability of the cooking appliance, but also the assembly convenience between the heat preservation cover 120 and the heating device 140 is improved, facilitating the disassembly or installation of the partition portion, enhancing the use convenience and practicality of the cooking appliance, and reducing the use cost of the cooking appliance.

[0093] As Figure 3 and Figure 8 shown in the figure, the first connection structure 10 is a plug post provided at the bottom of the heat preservation cover 120, and the second connection structure 20 is a plug block provided at the top of the heating device 140. A plug hole 21 is provided on the plug block. The plug post and the plug block with the plug hole 21 not only have a simple structure and are convenient for processing and manufacturing, but also the connection method in which the plug post cooperates with the plug block with the plug hole 21 simplifies the disassembly and assembly process of the heat preservation cover 120 and the heating device 140, thus facilitating the replacement of the partition portion.

[0094] Specifically, as Figure 8 shown in the figure, the first connection structure 10 includes a connected connection section 15 and a plug section 16 in a direction away from the heat preservation cover 120. Among them, the plug section 16 extends longitudinally, and the bottom end of the plug section 16 protrudes from the bottom surface of the heat preservation cover 120. In this way, the part of the plug section 16 protruding from the bottom surface of the heat preservation cover 120 can be more conveniently inserted into the plug hole 21, thereby improving the assembly convenience of the heat preservation cover 120 and the heating device 140.

[0095] As Figure 8As shown, in order to further improve the connection stability between the heat insulation cover 120 and the heating device 140, mounting holes 161 are formed in the insertion section 16, and fasteners sequentially pass through the mounting holes 161 and the insertion holes 21 to tightly connect the insertion posts and the insertion blocks.

[0096] As Figure 3 shown, in order to clamp the partition part along the circumference of the partition part by the heat insulation cover 120 and the heating device 140, both the first connection structure 10 and the second connection structure 20 are multiple. The multiple first connection structures 10 and the multiple second connection structures 20 are arranged in one-to-one correspondence and are spaced circumferentially around the heat insulation cover 120.

[0097] Optionally, the heat insulation cover 120 is made of plastic.

[0098] Optionally, the wall thickness of the heat insulation cover 120 is greater than or equal to 1.5 mm and less than or equal to 4 mm.

[0099] Optionally, the height of the heat insulation cover 120 is greater than or equal to 45 mm and less than or equal to 85 mm.

[0100] As Figures 1 to 3 shown, the heating device 140 includes a heating plate 141 and a support cylinder part 142 connected to the heating plate 141 and extending upward. The partition part is clamped between the heat insulation cover 120 and the support cylinder part 142, and the second connection structure 20 is located on the support cylinder part 142. Among them, the support cylinder part 142 and the heating plate 141 are of an integral structure or are detachably connected. The top annular surface of the support cylinder part 142 and the bottom annular surface of the heat insulation cover 120 have equal areas to achieve a stable clamping effect on the partition part.
