Description

Technical Field

[0001] This application relates to the technical field of small household appliances, and particularly to a cooking appliance. Background Art

[0002] Most of the existing cooking appliances use bottom heating to heat the food in the inner pot, such as electric slow cookers, rice cookers, etc. However, this heating method inevitably has a large part of the heat diffusing from the bottom of the heating device to the periphery, resulting in a large amount of heat waste, and will cause the temperature rise of the outer shell of the cooker body to be too high. At the same time, for an inner pot with poor thermal conductivity, such as a ceramic inner pot, its bottom receives heat by directly contacting the heating device, but its side is not heated, and it cannot effectively heat the food in the inner pot evenly.

[0003] There are also some cooking appliances that are provided with a heat conduction structure on the side of the ceramic inner pot to transfer the bottom heat to the side of the inner pot and improve the uniformity of the food being heated. However, since the material of the inner pot is ceramic and the dimensional tolerance is relatively large, a certain gap usually needs to be reserved during design to cope with various deformations, and it is difficult to achieve the fitting of the heat conduction structure and the side wall of the inner pot. Due to the gap between the heating device and the side wall of the ceramic inner pot, this type of cooking appliance will not produce effective contact, and the heat can only be transferred to the ceramic inner pot by radiation, resulting in low thermal efficiency and long cooking time. Summary of the Utility Model

[0004] Based on this, it is necessary to provide a cooking appliance to solve the problems of heat waste and low thermal efficiency.

[0005] A cooking appliance includes: a cooker body, an inner pot, a heating element, and a heat conducting member. The inner pot is disposed inside the cooker body. The heating element is disposed below the bottom wall of the inner pot. The heat conducting member is in a multi-petal shape and includes a heat conducting bottom wall and a heat conducting side wall extending upward from the heat conducting bottom wall to the outside of the side wall of the inner pot. The heat conducting bottom wall is located below at least a part of the bottom wall of the heating element, and the heat conducting side wall is in close contact with the side wall of the inner pot.

[0006] The cooking appliance provided by this application, by providing a heat conducting member, and the heat conducting member includes a heat conducting bottom wall and a heat conducting side wall, the heat radiated upward by the heating element is directly transferred to the inner pot to heat the inner pot. The heat radiated downward by the heating element can be transferred to the heat conducting bottom wall, and then transferred to the heat conducting side wall through the heat conducting bottom wall, and finally transferred to the side wall of the inner pot through the contact heat transfer between the heat conducting side wall and the side wall of the inner pot. In this way, using the heat radiated downward by the heating element to heat the side wall of the inner pot not only avoids heat waste, reduces the temperature rise of the cooker body, but also enables the bottom wall and the side wall of the inner pot to be heated together to form a three-dimensional heating, so that the inner pot and the food in it are heated evenly, improves the thermal efficiency of the heating element, and thus greatly shortens the cooking time.

[0007] In one embodiment, a plurality of circumferentially distributed partition grooves are formed in the heat conducting member, the partition grooves penetrate through the inner and outer side surfaces of the heat conducting member, the partition grooves extend downward from the top end of the heat conducting side wall to the connection between the heat conducting side wall and the heat conducting bottom wall, or extend to at least a part of the heat conducting bottom wall, and the partition grooves divide the heat conducting side wall into at least multiple segments.

[0008] In this way, by providing the partition grooves, the heat conducting member has a multi-segmented structure, and the side wall of the heat conducting member has a tendency to converge towards the center. As long as the outer diameter of the inner pot is greater than the inner diameter of the heat conducting side wall in its natural state, when the inner pot is installed in the pot body, the heat conducting side wall of the heat conducting member can be elastically deformed to closely adhere to the inner pot by itself, thereby facilitating the improvement of heat transfer efficiency and heat transfer uniformity. Moreover, the heat conducting member arranged in this way can adapt to inner pots with different size deviations, avoiding the problem of low heat transfer efficiency caused by the existence of a gap between the heat conducting member and the inner pot.

[0009] In one embodiment, a through hole is formed in the central region of the heat conducting bottom wall, and the partition groove extends downward from the top end of the heat conducting side wall to the through hole to divide the heat conducting member into a plurality of independently arranged heat conducting sheets.

[0010] In this way, the installation positions of the multiple independent heat conducting sheets can be adjusted respectively, so that each heat conducting sheet can be closely attached to the side wall of the inner pot, thereby improving the heat transfer efficiency. Moreover, the heat conducting member arranged in this way can adapt to inner pots with different size deviations, avoiding the problem of low heat transfer efficiency caused by the existence of a gap between the heat conducting member and the inner pot.

[0011] In one embodiment, the heating element is arranged as a heating disc, and the shape of the heat conducting bottom wall is adapted to the shape of the bottom wall of the heating disc.

[0012] In this way, the heat conducting bottom wall can be close to or closely attached to the bottom wall of the heating disc, which is beneficial to the heat transferred downward by the heating disc to be transferred to the heat conducting bottom wall.

[0013] In one embodiment, the heating disc includes a disc body portion and a heat pipe portion arranged below the disc body portion. A heat transfer surface is provided at the bottom surface of the disc body portion near the edge, and a heat conducting surface is provided on the heat conducting bottom wall, and the heat conducting surface is in contact with the heat transfer surface.

[0014] In this way, good contact heat transfer between the heating element and the heat conducting member can be realized through the contact between the heat transfer surface and the heat conducting surface, ensuring the heat transfer effect of the heat conducting member.

[0015] In one embodiment, both the heat conducting surface and the heat transfer surface are arranged as flat surfaces.

[0016] In this way, the effective contact between the heat conducting surface and the heat transfer surface can be ensured, and the heat transfer effect can be ensured.

[0017] In one embodiment, the heat-conducting surface is provided with mounting holes, the heat-transferring surface is provided with fixing holes, and a fastener connects the mounting holes and the fixing holes to connect the heat-conducting member to the heating plate.

[0018] In this way, by connecting the heat-conducting surface of the heat-conducting member and the heat-transferring surface of the heating plate with a fastener, it not only provides effective support for the heat-conducting member, but also ensures effective contact between the heat-conducting surface and the heat-transferring surface.

[0019] In one embodiment, the heat-conducting bottom wall is provided with an extension corresponding to the heat pipe portion, and the extension is located below the heat pipe portion.

[0020] Since a heating tube is provided in the heat pipe portion and the heat is relatively high, by providing an extension below the heat pipe portion, more heat dissipated by the heating element can be utilized, further improving the thermal efficiency.

[0021] In one embodiment, a deformation angle is provided at the connection between the heat-conducting bottom wall and the heat-conducting side wall, the separation groove at least penetrates the deformation angle along the radial direction of the heat-conducting member, and the deformation angle is used to deform when the inner pot is inserted into the inside of the heat-conducting member to elastically fit the heat-conducting side wall to the side wall of the inner pot.

[0022] In this way, the separation groove at least penetrates the deformation angle along the radial direction of the heat-conducting member to ensure that the deformation angle can play its elastic deformation role. The elastic deformation role of the deformation angle can reduce the elastic stress at the connection between the heat-conducting bottom wall and the heat-conducting side wall when the heat-conducting member deforms, thereby reducing the probability of deformation and damage of the heat-conducting member due to long-term heating.

[0023] In one embodiment, the deformation angle is set as a downward concave arc groove.

[0024] In this way, the arc groove can improve the elastic effect, thereby increasing the service life of the heat-conducting member. In addition, the arc groove can also be used as a diversion groove to divert the water flowing to the inside of the heat-conducting member to a preset area, avoiding water flowing onto the pins of the heating element and causing potential safety hazards.

[0025] In one embodiment, a heating device is provided on the side of the heat-conducting side wall facing away from the inner pot.

[0026] In this way, the heating effect on the side wall of the inner pot is further improved, thereby improving the heating efficiency and being beneficial to further shortening the cooking time.

[0027] In one embodiment, the inner pot is made of ceramic material.

[0028] Ceramic materials have good heat insulation performance and are suitable for stewing food. However, on the one hand, the heat conductivity of the inner ceramic pot is low, which easily leads to uneven heating. On the other hand, the heat shock resistance of the inner ceramic pot is poor. When the local part is directly in contact with the heating element, there is a risk of cracking when subjected to heat shock. Therefore, by setting a heat conducting member including a heat conducting bottom wall and a heat conducting side wall outside the inner ceramic pot, the bottom wall of the inner ceramic pot is heated by directly contacting the heating element, and at the same time, the side wall of the inner ceramic pot receives the heat conducted by the heat conducting member, forming a three-dimensional heating, so that the inner pot and the ingredients therein are heated evenly, improving the heat efficiency of the heating element and thus greatly shortening the cooking time.

[0044] Please refer to Figures 1 to 3 , this application provides a cooking appliance, including: a pot body 10, an inner pot 20, a heating element 30, and a heat conducting element 40. The inner pot 20 is disposed inside the pot body 10, the heating element 30 is disposed below the bottom wall of the inner pot 20, the heat conducting element 40 is multi-petal shaped, the heat conducting element 40 includes a heat conducting bottom wall 41 and a heat conducting side wall 42 extending upward from the heat conducting bottom wall 41 to the outside of the side wall of the inner pot 20. The heat conducting bottom wall 41 is located below at least a part of the bottom wall of the heating element 30, and the heat conducting side wall 42 is in close contact with the side wall of the inner pot 20. In this way, by providing the heat conducting element 40, and the heat conducting element 40 includes a heat conducting bottom wall 41 and a heat conducting side wall 42, the heat dissipated upward by the heating element 30 is directly transferred to the inner pot 20 to heat the inner pot 20, and the heat dissipated downward by the heating element 30 can be transferred to the heat conducting bottom wall 41, and transferred to the heat conducting side wall 42 through the heat conducting bottom wall 41, and finally transferred to the side wall of the inner pot 20 through the heat transfer by the contact between the heat conducting side wall 42 and the side wall of the inner pot 20. In this way, using the heat dissipated downward by the heating element 30 to heat the side wall of the inner pot 20 not only avoids heat waste, reduces the temperature rise of the pot body 10, but also enables the bottom wall and the side wall of the inner pot 20 to be heated together, forming a three-dimensional heating, so that the inner pot 20 and the food materials therein are heated evenly, improving the thermal efficiency of the heating element 30, and thus greatly shortening the cooking time.

[0045] In this embodiment, the inner pot 20 can be taken out of the heat conducting element 40 and can also be put into the heat conducting element 40. In this way, it is very convenient to use and it is convenient to clean the inner pot 20. The heat conducting element 40 and the heating element 30 are set to be non-removably disposed in the pot body 10. In this way, it can be avoided that the heat conducting element 40 and the heating element 30 are taken out when the inner pot 20 is taken off.

[0046] In one embodiment, the inner pot 20 is made of ceramic material, that is, the inner pot 20 is a ceramic pot. The ceramic material has good heat preservation performance and is suitable for stewing food.

[0047] Please refer to Figure 2 and Figure 3, In one embodiment, a plurality of circumferentially distributed partition grooves 43 are formed in the heat conducting member 40. The partition grooves 43 penetrate through the inner and outer side surfaces of the heat conducting member 40. The partition grooves 43 extend downward from the top end of the heat conducting side wall 42 to the connection between the heat conducting side wall 42 and the heat conducting bottom wall 41, or extend to at least a part of the heat conducting bottom wall 41. The partition grooves 43 divide the heat conducting side wall 42 into at least multiple petals. In this way, by providing the partition grooves 43, the heat conducting member 40 has a multi-petal structure, and the side wall of the heat conducting member 40 has a tendency to converge towards the center. As long as the outer diameter of the inner pot 20 is greater than the inner diameter of the heat conducting side wall 42 in its natural state, when the inner pot 20 is installed in the pot body 10, the heat conducting side wall 42 of the heat conducting member 40 can be elastically deformed to closely adhere to the inner pot 20 by itself, which is beneficial to improving the heat transfer efficiency and heat transfer uniformity. Moreover, the heat conducting member 40 arranged in this way can adapt to inner pots 20 with different dimensional deviations, avoiding the problem of low heat transfer efficiency caused by a gap between the heat conducting member 40 and the inner pot 20.

[0048] Please refer to Figure 7 and Figure 8 , which is a schematic structural diagram of another embodiment of the heat conducting member 40. The difference between this embodiment and the Figure 3 shown embodiment is that a through hole 415 is formed in the central region of the heat conducting bottom wall 41, and the partition groove 43 extends downward from the top end of the heat conducting side wall 42 to the through hole 415 to divide the heat conducting member 40 into multiple independently arranged heat conducting sheets 45. This embodiment can also be understood as: the heat conducting member 40 includes multiple independently arranged heat conducting sheets 45, and the multiple heat conducting sheets 45 are arranged at intervals along the circumference of the inner pot and wrap around the outside of the lower part of the inner pot 20. In this way, the multiple independent heat conducting sheets 45 can adjust their installation positions respectively, so that each heat conducting sheet 45 can be closely attached to the side wall of the inner pot 20, thereby improving the heat transfer efficiency. Moreover, the heat conducting member 40 arranged in this way can adapt to inner pots 20 with different dimensional deviations, avoiding the problem of low heat transfer efficiency caused by a gap between the heat conducting member 40 and the inner pot 20.

[0049] The heat conducting member 40 is a metal member, and metals have fast heat transfer and good heat conduction effects. Further, the heat conducting member 40 can be an aluminum alloy member or a copper member, and this application does not limit this.

[0050] Please refer to Figures 2 to 5 , further, the heating member 30 is arranged as a heating plate, and the shape of the heat conducting bottom wall 41 is adapted to the shape of the bottom wall of the heating plate. In this way, the heat conducting bottom wall 41 can be close to or closely attached to the bottom wall of the heating plate, which is beneficial to the heat dissipated downward by the heating plate being transferred to the heat conducting bottom wall 41. It is worth mentioning that "the shapes are adapted" does not mean that the shapes are the same. As long as the heat conducting bottom wall 41 wraps around the outside of the bottom wall of the heating plate, whether the heat conducting bottom wall 41 is in contact with or has a gap with the bottom wall of the heating plate can be regarded as the shape of the heat conducting bottom wall 41 being adapted to the shape of the bottom wall of the heating plate.

[0051] Further, the heating plate includes a plate body portion 31 and a heat pipe portion 32 disposed below the plate body portion 31. It can be understood that a heating tube is provided inside the heat pipe portion 32. A heat transfer surface 311 is provided at the bottom surface of the plate body portion 31 near the edge, and a heat conducting surface 411 is provided on the heat conducting bottom wall 41. The heat conducting surface 411 is in contact with the heat transfer surface 311. In this way, good contact heat transfer between the heating element 30 and the heat conducting element 40 can be achieved through the contact between the heat transfer surface 311 and the heat conducting surface 411, ensuring the heat transfer effect of the heat conducting element 40.

[0052] In one embodiment, both the heat conducting surface 411 and the heat transfer surface 311 are provided as flat surfaces. In this way, effective contact between the heat conducting surface 411 and the heat transfer surface 311 can be ensured, guaranteeing the heat transfer effect.

[0053] Please refer to Figure 2 and Figure 3 Furthermore, the heat conducting surface 411 is provided with a mounting hole 412, and the heat transfer surface 311 is provided with a fixing hole 312. A fastener connects the mounting hole 412 and the fixing hole 312 to connect the heat conducting element 40 to the heating plate. In this way, by connecting the heat conducting surface 411 of the heat conducting element 40 and the heat transfer surface 311 of the heating plate with a fastener, effective support is provided for the heat conducting element 40, and effective contact between the heat conducting surface 411 and the heat transfer surface 311 is ensured.

[0054] Further, the heat conducting bottom wall 41 is provided with an extension portion 413 corresponding to the heat pipe portion 32, and the extension portion 413 is located below the heat pipe portion 32. Since a heating tube is provided inside the heat pipe portion 32 and the heat is relatively high, by providing the extension portion 413 below the heat pipe portion 32, more heat dissipated by the heating element 30 can be utilized, further improving the thermal efficiency. In this embodiment, the extension portion 413 is in contact with the heat pipe portion 32, and the heat transfer effect is better.

[0055] Further, the heat conducting bottom wall 41 is provided with a pin avoiding hole 414 corresponding to the pins of the heating element 30. In this way, by providing the pin avoiding hole 414 to avoid the pins on the heating element 30, the pins can pass through the heat conducting element 40 to be connected to the power supply line.

[0056] Further, please refer to Figure 2 、 Figure 3 and Figure 5, a deformation angle 421 is provided at the connection between the heat-conducting bottom wall 41 and the heat-conducting side wall 42. The separation groove 43 penetrates at least the deformation angle 421 along the radial direction of the heat-conducting member 40. The deformation angle 421 is used to deform when the inner pot 20 is inserted into the inner side of the heat-conducting member 40, so that the heat-conducting side wall 42 elastically fits against the side wall of the inner pot 20. In this way, the separation groove 43 penetrates at least the deformation angle 421 along the radial direction of the heat-conducting member 40, ensuring that the deformation angle 421 can play its elastic deformation role. The elastic deformation role of the deformation angle 421 can reduce the elastic stress at the connection between the heat-conducting bottom wall 41 and the heat-conducting side wall 42 when the heat-conducting member 40 deforms, thereby reducing the probability of deformation and damage of the heat-conducting member 40 due to long-term heating.

[0057] In this embodiment, the deformation angle 421 is set as a downward concave arc groove. In this way, the arc groove can improve the elastic effect, thereby improving the service life of the heat-conducting member 40. In addition, the arc groove can also be used as a diversion groove to divert the water flowing to the inner side of the heat-conducting member 40 to a preset area, avoiding water flowing onto the pins of the heating element 30 and causing potential safety hazards.

[0058] Furthermore, a diversion groove or a diversion hole is provided at the connection between the heat-conducting bottom wall 41 and the heat-conducting side wall 42. In this way, when water flows down along the side wall of the inner pot 20 to the inner side of the heat-conducting member 40, the diversion groove or the diversion hole can divert the water to a preset area, avoiding water flowing onto the pins of the heating element 30 and causing potential safety hazards.

[0059] As Figure 6 shown, in one embodiment, a heating device 50 is provided on the side of the heat-conducting side wall 42 facing away from the inner pot 20. In this way, the heating effect on the side wall of the inner pot 20 is further improved, thereby improving the heating efficiency and being beneficial to further shortening the cooking time. The heating device 50 can be a heating wire, a heating tape, a heating film, etc.

[0060] Furthermore, please refer to Figure 2 and Figure 3 , the top end of the heat-conducting side wall 42 is bent outward in an arc to form an outer folded edge 422. In this way, when the inner pot 20 is placed inside the heat-conducting member 40, the top end of the heat-conducting member 40 can be prevented from scratching the inner pot 20, so that the inner pot 20 will not be worn.

[0061] As Figure 1 shown, the cooking appliance provided by the present application is an electric slow cooker, but it is not limited thereto. The cooking appliance can also be a rice cooker, an electric frying pan, an electric hot pot, etc.

[0062] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0063] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
