Description

Technical Field

[0001] This application relates to the field of household appliance technology, specifically to a food warmer. Background Technology

[0002] Food warmers are primarily used for heating and keeping warm foods such as rice and milk, and also have auxiliary functions such as defrosting. Through a built-in heating element, the surface of the warmer heats up quickly to continuously heat utensils and food placed on it. With a temperature control system, the warmer achieves heat retention, allowing food to stay fresh and warm for an extended period.

[0003] The food warmer's panel is used to place food and is the part that the user directly touches. Heat generated by the heating element is evenly transferred to the food through the panel to keep it warm. A temperature control device detects the temperature of the utensils placed on the panel to maintain the warmer at the appropriate temperature.

[0004] In related technologies, the temperature control device is located below the panel. This device detects the panel's temperature to obtain the temperature of the utensils on it, but the results are not accurate enough. To improve accuracy, direct contact between the temperature control device and the utensils would require a through-hole in the panel. However, liquids on the panel can easily enter the warming board through this hole, affecting its performance and potentially causing safety hazards. Utility Model Content

[0005] This application provides a food warmer that can solve the problem of liquid entering between the panel and the temperature control device, which affects the working performance of the food warmer and may even cause safety hazards.

[0006] This application provides a food warmer, which includes:

[0007] A first panel has a first surface and a second surface opposite each other along the thickness direction. The first surface is used to place food. The first panel is provided with a first mounting hole penetrating the first surface and the second surface.

[0008] A heating device is disposed on a second side of the first panel for heating the food via the first panel;

[0009] A temperature control device, which is electrically connected to the heating device, is disposed through the first mounting hole;

[0010] A waterproof box having a receiving cavity is disposed on the second side of the first panel, and the orthographic projection of the waterproof box completely covers the orthographic projection of the first mounting hole along the thickness direction of the first panel.

[0011] The food warmer provided in this application has a heating device located on the second side of a first panel. The first panel can then be used to transfer heat generated by the heating device to heat food, utensils, etc., placed on it. A temperature control device can be used to control the heating temperature of the heating device to maintain the food and utensils at an appropriate temperature. Since at least a portion of the temperature control device can pass through mounting holes in the first panel, the temperature control device can directly contact the bottom of the utensil, which is beneficial for improving detection accuracy.

[0012] Furthermore, since the first panel has mounting holes, the orthographic projection of the waterproof box 140 along the thickness direction X can completely cover the orthographic projection of the first mounting hole 110c along the thickness direction X. When the food warmer is heated and liquid food overflows from the utensil, the liquid can enter the interior of the food warmer through the gap between the temperature control device and the first panel and then flow into the waterproof box. This reduces the possibility of liquid flowing onto the electrical components inside the food warmer, thus affecting the working performance of the food warmer.

[0013] Therefore, in this embodiment, placing food or utensils on the first panel enables the heating function. The temperature control device is in direct contact with the utensils, effectively improving detection accuracy. Furthermore, the waterproof box reduces the possibility of leakage affecting the performance of the food warmer or even causing safety hazards.

[0014] According to one embodiment of this application, it further includes a mounting portion and an elastic member. The mounting portion is disposed on the first panel along the thickness direction of the first panel, and the elastic member is located between the temperature control device and the mounting portion to allow the temperature control device to move elastically along the thickness direction. The mounting portion is located in the receiving cavity.

[0015] One end of the elastic element can abut against the mounting part, and the other end of the elastic element can abut against the temperature control device, thereby allowing the temperature control device to move elastically along the thickness direction of the first panel. Furthermore, when liquid enters the interior of the warming plate through the first mounting hole, the liquid flows downwards along the outer wall of the mounting part. Therefore, by positioning the mounting part within the receiving cavity, liquid on the mounting part can also flow into the waterproof box, thereby reducing the possibility of liquid flowing to other electrical components.

[0016] According to one embodiment of this application, the heating device is arranged around the second surface of the first panel, and along the radial direction of the heating device, the sidewall of the waterproof box is located between the mounting portion and the heating device.

[0017] By circling the heating device on the second side of the first panel, the uniformity of heating on the first panel can be improved, thereby improving the uniformity of heating food.

[0018] As an electrical component, the heating device converts electrical energy into heat energy when energized, thereby generating heat to provide warmth to the first panel. Therefore, by placing a waterproof box between the mounting part and the heating device along its radial direction, the waterproof box can prevent liquid from flowing from the mounting part to the heating device when liquid enters the interior of the warming plate through the first mounting hole, reducing the risk of short circuits caused by water immersion.

[0019] According to one embodiment of this application, the waterproof box is provided with a drainage channel. Along the thickness direction of the first panel, the drainage channel is located at one end away from the opening of the waterproof box, and the drainage channel is used to drain the liquid inside the waterproof box to the outside of the warming board.

[0020] By setting up drainage channels, liquid entering the waterproof box can flow out to the outside of the cutting board in a timely manner, thereby reducing the possibility of liquid accumulating in the waterproof box, causing excessive liquid inside the box, and rendering the waterproof box ineffective.

[0021] According to one embodiment of this application, the warming board further includes:

[0022] The second panel has a second mounting hole, and the first panel is disposed in the second mounting hole;

[0023] A heat insulation element, located radially from the second mounting hole, is partially situated between the first panel and the second panel, the heat insulation element preventing heat transfer from the first panel to the second panel.

[0024] The second panel can be used to support appliances. Since the first panel has a heating element, it can be used to heat appliances. Therefore, by installing heat insulation, heat loss can be prevented from diffusing outwards from the first panel, thus concentrating the heat on the first panel and reducing energy consumption. The temperature of the second panel is lower than that of the first panel. Appliances placed on the first panel achieve the heating function. Appliances placed on the second panel achieve the heat preservation function.

[0025] According to one embodiment of this application, the heat insulation member has a heat insulation cavity, and at least a portion of the heat insulation member surrounds the outer periphery of the first panel so that the first panel is located within the heat insulation cavity;

[0026] Part of the waterproof box is located inside the heat insulation cavity, and the heat insulation component has a through hole through which the waterproof box can pass.

[0027] Since the first panel is located inside the heat insulation cavity, the heating device is also located inside the heat insulation cavity. The heat insulation component allows the heat generated by the heating device to be concentrated within the heat insulation cavity, preventing the heat from easily diffusing outwards or downwards away from the first panel. This allows heat to flow upwards from the first surface of the first panel, creating a hot airflow above the first panel and preventing food on the warming plate from cooling down. Furthermore, it also prevents heat from diffusing downwards to the bottom cover and other plastic structures, reducing the possibility of deformation of these structures due to heat.

[0028] According to one embodiment of this application, the drainage channel protrudes from the end face away from the opening of the waterproof box;

[0029] The warming plate also includes a bottom cover, which is connected to the second panel, and the bottom cover is provided with at least one first drainage hole.

[0030] Liquid inside the waterproof box can flow into the bottom cover through the drainage channel and then drain out to the outside of the warming board through the first drainage hole on the bottom cover. By setting the drainage channel to protrude from the end face of the waterproof box opposite to the opening, the drainage channel can have a guiding function to direct the liquid to the bottom cover.

[0031] According to one embodiment of this application, the bottom cover has a surrounding plate on the side facing the first panel, the surrounding plate forming an internal space, the drainage channel is disposed outside the surrounding plate, and the first drainage hole is located outside the surrounding plate.

[0032] Since the internal space formed by the enclosure can be used to accommodate components such as wire harnesses, liquid is not easily allowed to enter the enclosure. Therefore, the end of the drainage channel away from the waterproof box corresponds to the outside of the enclosure, and the first drainage hole is also located on the outside of the enclosure to prevent liquid from flowing into the internal space of the enclosure.

[0033] According to one embodiment of this application, it further includes a turntable bracket, which is located between the waterproof box and the bottom cover along the thickness direction of the first panel. The turntable bracket is provided with a second drainage hole, and the drainage channel passes through the second drainage hole.

[0034] When the turntable support is located between the waterproof box and the bottom cover, the liquid inside the waterproof box can first enter the second drain hole of the turntable support through the drain channel, and then flow to the bottom cover through the second drain hole. Finally, the liquid can flow out to the outside of the warming board through the first drain hole on the bottom cover.

[0035] According to one embodiment of this application, the heat insulation member is provided with a first adhesive application portion and a second adhesive application portion;

[0036] The first glue application part is located on the side of the heat insulation member facing the first panel; the second glue application part is located on the side of the heat insulation member facing the second panel.

[0037] The first and second sealing sections can be used to accommodate waterproof adhesive. The waterproof adhesive allows the insulation component to be sealed to the first and second panels, preventing liquids on the first or second panel from entering the warming plate through the gap between the insulation component and the first or second panel.

[0038] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the warming plate provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0062] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0063] A food warmer, as a household appliance, is mainly used to keep food warm and prevent it from getting cold during group meals or solo dining.

[0064] A food warmer includes a heating element and a panel for placing food and utensils. The heating element is located on the panel to provide heat, thereby heating and keeping food warm. The food warmer also includes a temperature control device. This device can detect the temperature of the utensils placed on the panel to maintain the food warmer at a suitable temperature.

[0065] In related technologies, the temperature control device is located below the panel. This device detects the panel's temperature to obtain the temperature of the utensils on it, but the results are not accurate enough. To improve accuracy, direct contact between the temperature control device and the utensils would require a through-hole in the panel. However, liquids on the panel can easily enter the warming board through this hole, affecting its performance and potentially causing safety hazards.

[0066] Therefore, based on the aforementioned technical problems, the applicant has improved the structure of the existing food warming board. In this embodiment, since the heating device is located on the second side of the first panel, the first panel can be used to transfer the heat generated by the heating device to heat food, utensils, etc., placed on the first panel. A temperature control device can be used to control the heating temperature of the heating device to maintain the food and utensils at an appropriate temperature. Since at least a portion of the temperature control device can pass through the mounting holes on the first panel, the temperature control device can directly contact the bottom of the utensil, which is beneficial for improving detection accuracy.

[0067] In addition, since the first panel has mounting holes, by setting a waterproof box below the temperature control device, when the food warmer is heated and liquid food overflows from the utensil, the liquid can enter the inside of the food warmer through the gap between the temperature control device and the first panel, and then flow into the waterproof box. This reduces the possibility of liquid flowing onto the electrical components inside the food warmer, thus affecting the working performance of the food warmer.

[0068] Therefore, in this embodiment, placing food or utensils on the first panel enables the heating function. The temperature control device is in direct contact with the utensils, effectively improving detection accuracy. Furthermore, the waterproof box reduces the possibility of leakage affecting the performance of the food warmer or even causing safety hazards.

[0069] The food warmer 100 provided in this application will now be described with reference to the accompanying drawings and specific embodiments.

[0070] See Figures 1 to 4 As shown, the food warmer 100 in this embodiment of the application includes a first panel 110, a heating device 120, a temperature control device 130, and a waterproof box 140.

[0071] The first panel 110 has a first surface 110a and a second surface 110b opposite to each other along the thickness direction X. The first surface 110a can be used to place food. In other words, when the user uses the food warming board 100, the first surface 110a can be the visible surface of the food warming board 100. The second surface 110b is the inner surface of the food warming board 100.

[0072] Food can be placed directly on the first surface 110a of the first panel 110, or it can be placed in utensils such as tableware or pots. The first panel 110 can transfer heat to the utensils to heat the food inside. The first panel 110 is provided with a first mounting hole 110c that passes through the first surface 110a and the second surface 110b.

[0073] The heating device 120 can be disposed on the second surface 110b of the first panel 110. The heat generated by the heating device 120 can be transferred to the first panel 110 to heat food through the first panel 110. The temperature control device 130 can be electrically connected to the heating device 120. At least a portion of the temperature control device 130 can pass through the first mounting hole 110c.

[0074] The waterproof box 140 has a receiving cavity 140a. The waterproof box 140 is disposed on the second surface 110b of the first panel 110. Along the thickness direction X of the first panel 110, the orthographic projection of the waterproof box 140 can completely cover the orthographic projection of the first mounting hole 110c.

[0075] In this embodiment, the first panel 110 is mainly used for heat conduction, and the heat generated by the heating device 120 can be transferred to the first panel 110. When the appliance is placed on the first panel 110, the appliance can be heated. The temperature control device 130 can control the operation of the heating device 120 so that the appliance can maintain a suitable temperature.

[0076] In some examples, the temperature control device 130 may have the function of detecting and controlling the bottom temperature of the appliance. For example, when the temperature control device 130 detects that the bottom temperature of the appliance has reached a preset temperature, it may control the heating device 120 to stop heating. When the temperature control device 130 detects that the bottom temperature of the appliance is lower than the preset temperature, it may control the heating device 120 to increase the heating power.

[0077] Since at least a portion of the temperature control device 130 can pass through the first mounting hole 110c, the end of the temperature control device 130 can extend beyond the first surface 110a of the first panel 110 for direct contact with the bottom of the appliance, thereby improving the accuracy of temperature detection and control of the appliance.

[0078] When liquid food is spilled onto the first panel 110, or when liquid food in the appliance overflows onto the first panel 110 due to heating, the liquid can easily flow into the interior of the warming plate 100 through the first mounting hole 110c of the first panel 110, as at least a portion of the temperature control device 130 passes through it. This can cause the liquid to wet the electrical components inside the warming plate 100, resulting in a short circuit. Therefore, in this embodiment, by providing a waterproof box 140 below the temperature control device 130, when liquid enters the interior of the warming plate 100, the liquid can flow directly into the waterproof box 140, thereby reducing the possibility of liquid wetting the electrical components, affecting the normal operation of the warming plate 100, or even causing safety hazards.

[0079] Specifically, since the orthographic projection of the waterproof box 140 along the thickness direction X can completely cover the orthographic projection of the first mounting hole 110c along the thickness direction X, liquid can enter the waterproof box 140 downwards through the gap between the temperature control device 130 and the first panel 110. The waterproof box 140 may have a receiving cavity 140a to receive the entering liquid, thereby preventing liquid from entering the electrical components inside the food warmer 100 and affecting the working performance of the food warmer 100.

[0080] In some examples, the waterproof box 140 may be provided with a drain hole to release the liquid contained inside to the outside of the warming board 100. Alternatively, the waterproof box 140 may be detachably connected to the first panel 110 to allow for regular cleaning of the waterproof box 140 and to prevent odors and bacterial growth inside the waterproof box 140.

[0081] For example, the waterproof box 140 is detachably connected to the second surface 110b of the first panel 110. A first connecting post 111 may protrude from the second surface 110b of the first panel 110. The waterproof box 140 may have a connecting hole 140b. The waterproof box 140 can be fixed to the first connecting post 111 of the first panel 110 by screws. The screws may pass through the connecting hole 140b from the outside of the bottom of the waterproof box 140 to lock with the first connecting post 111.

[0082] In some examples, the temperature control device 130 can be flexibly connected to the first panel 110. By flexibly connecting the temperature control device 130 to the first panel 110, the temperature control device 130 can be adapted to appliances with different bottom shapes. If the bottom of the appliance is recessed to a greater depth, the temperature control device 130 will protrude a greater height from the first panel 110a; if the bottom of the appliance is recessed to a less depth, the temperature control device 130 will protrude a less height from the first panel 110a. This allows the temperature control device 130 to make full contact with the bottom of appliances with different degrees of recess, which helps to improve the accuracy of temperature detection.

[0083] In some examples, the temperature control device 130 may include a temperature controller 131 and a temperature-sensing cap 132. The temperature controller 131 may be located inside the temperature-sensing cap 132. The temperature-sensing cap 132 may extend through a first surface 110a of the first panel 110 for contact with an appliance. The temperature controller 131 may be electrically connected to the heating device 120. Based on the temperature detected by the temperature-sensing cap 132, the temperature controller 131 may control the heating state of the heating device 120.

[0084] In some examples, the first panel 110 can have good heat transfer properties. The first panel 110 can be formed from a metallic material to reduce material costs while achieving good heat transfer performance.

[0085] In some examples, the metal material of the first panel 110 may be, but is not limited to, aluminum, iron, etc. The material of the waterproof box 140 may be, but is not limited to, plastic.

[0086] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, the food warming board 100 of this embodiment may further include a mounting portion 150 and an elastic member 160. The mounting portion 150 is disposed on the first panel 110. Along the thickness direction X of the first panel 110, the elastic member 160 may be located between the temperature control device 130 and the mounting portion 150, so that the temperature control device 130 can move elastically along the thickness direction X. The mounting portion 150 is located in the receiving cavity 140a.

[0087] In this embodiment, one end of the elastic member 160 can abut against the mounting portion 150, and the other end of the elastic member 160 can abut against the temperature control device 130, thereby allowing the temperature control device 130 to move elastically along the thickness direction X of the first panel 110.

[0088] Furthermore, when liquid enters the interior of the warming plate 100 through the first mounting hole 110c, the liquid flows downward along the outer wall of the mounting part 150. Therefore, by setting the mounting part 150 in the receiving cavity 140a, the liquid on the mounting part 150 can also flow into the waterproof box 140, thereby reducing the possibility of liquid flowing to other electrical components.

[0089] In some examples, the second surface 110b of the first panel 110 may protrude and have a second connecting post 112. The mounting portion 150 may be located at the end of the second connecting post 112 away from the second surface 110b. Along the thickness direction X of the first panel 110, there is a gap between the mounting portion 150 and the temperature control device 130 to accommodate an elastic member 160. The elastic member 160 may be sleeved on the outside of the second connecting post 112. Both ends of the elastic member 160 abut against the mounting portion 150 and the temperature control device 130, respectively.

[0090] In some examples, the elastic element 160 may be, but is not limited to, a spring or a rubber element.

[0091] In some examples, the mounting portion 150 may be a screw structure. The mounting portion 150 may be locked to the second connecting post 112. The screw structure may have a large end face facing the first panel 110. The large end face may be abutted by a spring.

[0092] See also some of the possible implementation methods. Figure 4 and Figure 5 As shown, in this embodiment of the application, the heating device 120 is circumferentially disposed on the second surface 110b of the first panel 110. Along the radial direction of the heating device 120, the sidewall of the waterproof box 140 is located between the mounting portion 150 and the heating device 120.

[0093] In this embodiment of the application, by circumferentially distributing the heating device 120 on the second surface 110b of the first panel 110, the heating uniformity on the first panel 110 can be improved, thereby improving the uniformity of food heating.

[0094] As an electrical component, the heating device 120 converts electrical energy into heat energy when energized, thereby generating heat to provide heat to the first panel 110. Therefore, by placing a waterproof box 140 between the mounting portion 150 and the heating device 120 along the radial direction of the heating device 120, the waterproof box 140 can prevent liquid on the mounting portion 150 from flowing to the heating device 120 when liquid enters the interior of the warming plate 100 through the first mounting hole 110c, thus reducing the risk of short circuits caused by water immersion in the heating device 120.

[0095] In some examples, the heating device 120 may include at least one heating element 121. When there are two or more heating elements 121, the two or more heating elements 121 may be arranged coaxially. The two or more heating elements 121 may be evenly distributed on the second surface 110b of the first panel 110.

[0096] Along the thickness direction X of the first panel 110, the orthographic projection of the waterproof box 140 lies within the orthographic projection of the heating element 121 in the inner ring. The waterproof box 140 can prevent liquid from flowing to the heating element 121.

[0097] See also some of the possible implementation methods. Figure 4 As shown, the waterproof box 140 of this embodiment is provided with a drainage channel 141. Along the thickness direction X of the first panel 110, the drainage channel 141 is located at one end away from the opening of the waterproof box 140. The drainage channel 141 is used to drain the liquid inside the waterproof box 140 to the outside of the warming plate 100.

[0098] In this embodiment, the waterproof box 140 is provided with a drainage channel 141. Therefore, liquid entering the waterproof box 140 can flow out to the outside of the warming board 100 in a timely manner through the drainage channel 141, thereby reducing the possibility of liquid accumulating in the waterproof box 140, causing excessive liquid in the waterproof box 140, and thus rendering the waterproof effect of the waterproof box 140 ineffective.

[0099] In some examples, the bottom wall 142 of the waterproof box 140 may be provided with an inclined guide surface extending outward from the center of the bottom wall 142. The inclined guide surface can be used to guide liquid from the center of the bottom wall 142 to the outer periphery. The drainage channel 141 can be located near the outer periphery of the waterproof box 140. Therefore, liquid entering the warming plate 100 through the first mounting hole 110c flows downward through the second connecting post 112 and the mounting part 150. When the liquid flows to the bottom wall 142 of the waterproof box 140, the inclined guide surface of the bottom wall 142 can guide the liquid to the drainage channel 141 on the outer periphery, thereby promoting liquid drainage, improving drainage efficiency, and reducing the possibility that the liquid inside the waterproof box 140 cannot be drained in time, leading to a failure of the waterproof effect.

[0100] See also some of the possible implementation methods. Figures 4 to 6 As shown, the food warmer 100 in this embodiment may further include a second panel 170 and a heat insulation member 180.

[0101] The second panel 170 is provided with a second mounting hole 170a. The first panel 110 can be disposed in the second mounting hole 170a. Along the radial direction of the second mounting hole 170a, a portion of the heat insulation member 180 can be located between the first panel 110 and the second panel 170. The heat insulation member 180 blocks the transfer of heat from the first panel 110 to the second panel 170.

[0102] In this embodiment, the second panel 170 can also be used to support the appliance. Since the first panel 110 is provided with a heating device 120, the first panel 110 can be used to heat the appliance. Therefore, by providing a heat insulation member 180, the heat of the first panel 110 can be blocked from diffusing to the outer periphery, so that the heat on the first panel 110 is concentrated, thereby reducing heat loss and reducing energy consumption.

[0103] Because the second side 110b of the first panel 110 is equipped with a heating device 120, the temperature of the second panel 170 is lower than that of the first panel 110. For example, the temperature of the first panel 110 can reach over 500 degrees Celsius, while the temperature of the second panel 170 can be over 100 degrees Celsius. Therefore, placing an appliance on the first panel 110 can achieve a heating function, while placing an appliance on the second panel 170 can achieve a heat preservation function.

[0104] In some examples, the thermal insulation 180 can be detachably connected to the first panel 110 via fasteners.

[0105] See also some of the possible implementation methods. Figures 4 to 6 As shown, the heat insulation member 180 in this embodiment may have a heat insulation cavity 180a. At least a portion of the heat insulation member 180 may surround the outer periphery of the first panel 110, such that the first panel 110 is located within the heat insulation cavity 180a. A portion of the waterproof box 140 is located within the heat insulation cavity 180a. The heat insulation member 180 is provided with a through hole 180b through which the waterproof box 140 passes.

[0106] In this embodiment, the heating device 120 is disposed on the second surface 110b of the first panel 110. The first panel 110 is located within the heat insulation cavity 180a, therefore the heating device 120 is also located within the heat insulation cavity 180a. The heat insulation member 180 can concentrate the heat generated by the heating device 120 within the heat insulation cavity 180a, making it difficult for the heat to diffuse downwards to the outer periphery and away from the first panel 110. This allows heat to flow upwards towards the first surface 110a of the first panel 110, creating a hot airflow above the first panel 110, preventing the food on the warming plate 100 from cooling down. On the other hand, it can also prevent heat from diffusing downwards to the plastic structure such as the bottom cover 190, reducing the possibility of deformation of the plastic structure such as the bottom cover 190 due to heat.

[0107] In some examples, the size of the waterproof box 140 along the thickness direction X of the first panel 110 can be greater than or equal to the size of the thermal insulation element 180. When the size of the waterproof box 140 is smaller than the size of the thermal insulation element 180, the waterproof box 140 is located inside the thermal insulation element 180. Liquid inside the waterproof box 140 can easily seep into the thermal insulation element 180, which can easily affect the thermal insulation effect of the thermal insulation element 180, and also make it difficult to clean as liquid tends to accumulate inside the thermal insulation element 180.

[0108] When the size of the waterproof box 140 is larger than the size of the heat insulation component 180, the waterproof box 140 can pass through the through hole 180b of the heat insulation component 180. When the size of the waterproof box 140 is equal to the size of the heat insulation component 180, the drainage channel 141 of the waterproof box 140 can pass through the through hole 180b of the heat insulation component 180.

[0109] See also some of the possible implementation methods. Figure 4 and Figure 7 As shown, the drainage channel 141 may protrude from the end face away from the opening of the waterproof box 140. The warming plate 100 may also include a bottom cover 190. The bottom cover 190 is connected to the second panel 170 and has at least one first drainage hole 190a.

[0110] In this embodiment, the liquid inside the waterproof box 140 can flow into the bottom cover 190 through the drainage channel 141, and be discharged to the outside of the warming plate 100 through the first drainage hole 190a on the bottom cover 190.

[0111] By providing a drainage channel 141 that protrudes from the end face away from the opening of the waterproof box 140, the drainage channel 141 can have a guiding function to direct liquid to the bottom cover 190.

[0112] In some examples, the end of the drain channel 141 away from the waterproof box 140 may have a small gap with the bottom cover 190 to reduce the force of liquid impacting the surface of the bottom cover 190 when liquid flows to the bottom cover 190, thereby reducing the possibility of liquid splashing to the surroundings.

[0113] See also some of the possible implementation methods. Figure 7 As shown, in this embodiment of the application, the bottom cover 190 has a surrounding plate 191 on the side facing the first panel 110. The surrounding plate 191 can enclose and form an internal space 191a. The drainage channel 141 can be provided outside the surrounding plate 191, and the first drainage hole 190a is also located outside the surrounding plate 191.

[0114] The internal space 191a formed by the enclosure 191 can be used to accommodate functional components such as wiring harnesses to improve the functionality of the food warmer 100. For example, the food warmer 100 in this embodiment can be a circular structure. The food warmer 100 can rotate around the center to facilitate users in different positions to take food from the food warmer 100.

[0115] Since the internal space 191a formed by the enclosure 191 can be used to accommodate components such as wire harnesses, liquid is not easily allowed to enter the enclosure 191. Therefore, the end of the drainage channel 141 away from the waterproof box 140 corresponds to the outside of the enclosure 191, and the first drainage hole 190a is also located on the outside of the enclosure 191 to prevent liquid from flowing into the internal space 191a of the enclosure 191.

[0116] See also some of the possible implementation methods. Figure 4 and Figure 7 As shown, the food warming board 100 may also include a turntable support 200. Along the thickness direction X of the first panel 110, the turntable support 200 is located between the waterproof box 140 and the bottom cover 190, and the turntable support 200 is provided with a second drain hole 200a. The drain channel 141 passes through the second drain hole 200a.

[0117] In this embodiment, the turntable bracket 200 can be used to realize the rotatable function of the warming plate 100. It should be noted that the rotatable function of the warming plate 100 means that the first panel 110 and the second panel 170 can rotate relative to their own center. The first panel 110 and the second panel 170 can be connected to form an integral structure. The first panel 110 and the second panel 170 rotate synchronously. The bottom cover 190 can be used to provide stable support for the warming plate 100.

[0118] When the turntable support 200 is located between the waterproof box 140 and the bottom cover 190, the liquid in the waterproof box 140 can first enter the second drain hole 200a of the turntable support 200 through the drain channel 141, and then flow to the bottom cover 190 through the second drain hole 200a. Finally, the liquid can flow out to the outside of the warming plate 100 through the first drain hole 190a on the bottom cover 190.

[0119] See in some examples Figure 2 As shown, the food warmer 100 may also include a housing 210. The housing 210 is connected to the second panel 170. The housing 210 can be used to provide assembly for structures such as the heating device 120. The turntable bracket 200 and the bottom cover 190 are located on the side of the housing 210 facing away from the second panel 170.

[0120] See also some of the possible implementation methods. Figure 6 As shown, the heat insulation member 180 may be provided with a first adhesive application portion 181 and a second adhesive application portion 182. The first adhesive application portion 181 is provided on the side of the heat insulation member 180 facing the first panel 110. The second adhesive application portion 182 is provided on the side of the heat insulation member 180 facing the second panel 170.

[0121] In this embodiment, the first adhesive application portion 181 and the second adhesive application portion 182 can be used to contain waterproof adhesive. The waterproof adhesive can seal the heat insulation member 180 with the first panel 110 and the second panel 170 to prevent liquid on the first panel 110 or the second panel 170 from entering the warming plate 100 through the gap between the heat insulation member 180 and the first panel 110 and the second panel 170.

[0122] Specifically, the first adhesive application part 181 is disposed on the side of the heat insulation member 180 facing the first panel 110, and the waterproof adhesive can seal the first panel 110 and the heat insulation member 180 at the first adhesive application part 181. The waterproof adhesive can prevent liquid on the first panel 110 or the second panel 170 from entering the warming plate 100 through the gap between the heat insulation member 180 and the first panel 110.

[0123] The second sealing part 182 is provided on the side of the heat insulation member 180 facing the second panel 170. The waterproof adhesive can seal the second panel 170 and the heat insulation member 180 at the second sealing part 182. The waterproof adhesive can prevent liquid on the first panel 110 or the second panel 170 from entering the warming plate 100 through the gap between the heat insulation member 180 and the second panel 170.

[0124] In some examples, the first adhesive portion 181 may be a recessed structure facing the second surface 110b of the first panel 110.

[0125] In some examples, the second adhesive applicator 182 may be located on the side of the second panel 170 facing away from the bottom cover 190. There may be a gap between the second adhesive applicator 182 and the second panel 170 to accommodate the waterproof adhesive.
