Description

Trays and household appliances Technical Field

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

[0002] In related technologies, trays can only be used as separate shelves for refrigerators or ovens. That is, trays can only be used as separate cold or hot trays. Users can only choose the appropriate tray when they have different usage needs, which limits the convenience of use. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the first objective of this application is to propose a tray.

[0005] The second objective of this application is to propose a household appliance.

[0006] To achieve at least one of the above objectives, according to a first aspect of this application, a tray is provided, comprising a body, a first plate, and a heat storage component. The body has a receiving cavity with an opening on one side; the first plate is located on one side of the body and closes the opening of the receiving cavity; the heat storage component is disposed in the receiving cavity, located between the first plate and the body; when the tray moves from a first region to a second region, the heat storage component can heat the first plate, and the temperature of the first region is greater than the temperature of the second region; or when the tray moves from the first region to the second region, the heat storage component can cool the first plate, and the temperature of the first region is less than the temperature of the second region.

[0007] In this technical solution, the tray includes a body, a first plate, and a heat storage component. The body has a receiving cavity with an opening on one side for accommodating the cavity. The first plate is located on one side of the body and closes the opening of the receiving cavity, allowing the first plate to be installed together with the body. The heat storage component is disposed in the receiving cavity, between the first plate and the body, providing installation space for the heat storage component. Furthermore, the first plate and the body also protect the heat storage component from damage. When the tray moves from a first area to a second area, the heat storage component heats the first plate. Since the temperature of the first area is higher than that of the second area, the tray moves from a higher-temperature first area to a lower-temperature second area. When the tray is in the second area, the heat storage component heats the first plate, releasing previously stored heat to heat items or food placed on the tray, thus keeping them warm. When the tray moves from the first zone to the second zone, the heat storage component cools the first plate. Since the temperature of the first zone is lower than that of the second zone, the tray moves from a lower-temperature first zone to a higher-temperature second zone. When the tray is in the second zone, the heat storage component cools the first plate, absorbing heat from the surrounding environment, thereby cooling or warming the items or food placed on the tray. This application, by incorporating a temperature-maintaining heat storage component on the tray, allows the tray to be pre-cooled or pre-heated according to user needs, enabling it to cool or heat during use, thus keeping the items or food placed on the tray warm and improving user convenience.

[0008] In addition, the tray in the above-mentioned technical solution provided in this application may also have the following additional technical features:

[0009] In one technical solution of this application, optionally, the heat storage component includes a phase change material, which can release heat to heat the first plate when the phase change material moves from the first region to the second region; or the phase change material can absorb heat to cool the first plate when it moves from the first region to the second region.

[0010] In this technical solution, the heat storage component includes a phase change material (PCM). When the PCM moves from a first region to a second region, it releases heat to heat the first plate. By incorporating the PCM in the heat storage component, the tray moves from a higher-temperature first region to a lower-temperature second region. When the tray is in the second region, the PCM gradually transitions from its high-temperature phase to a low-temperature phase. During this process, the PCM releases previously absorbed heat, transferring it to the first plate to heat it and maintain a certain temperature for items or food placed on the tray. Conversely, when the PCM moves from a lower-temperature first region to a higher-temperature second region, the PCM absorbs heat to cool the first plate. Similarly, when the tray moves from a lower-temperature first region to a higher-temperature second region, the PCM gradually transitions from its low-temperature phase to a high-temperature phase. During this process, the PCM absorbs surrounding heat, cooling the first plate and maintaining a certain temperature for items or food placed on the tray.

[0011] In one technical solution of this application, optionally, the first plate has a heat-insulating area, and the main body is recessed in a direction away from the first plate to form a receiving cavity, the opening of the receiving cavity facing the first plate, and the heat storage component corresponds to the heat-insulating area.

[0012] In this technical solution, the first plate has a heat-insulating area, and the main body is recessed away from the first plate to form a receiving cavity. The opening of the receiving cavity faces the first plate. The heat storage component corresponds to the heat-insulating area, allowing the heat-insulating area to receive heat or cold transferred by the heat storage component more concentratedly. This correspondence between the heat storage component and the heat-insulating area makes heat transfer more precise and efficient. When the heat storage component releases heat, it can directly heat the heat-insulating area, thereby heating the entire tray and the food on it. When the heat storage component absorbs heat, it can effectively reduce the temperature of the heat-insulating area, thus maintaining the food at a low temperature.

[0013] In one technical solution of this application, optionally, the first plate is located in the receiving cavity, and the side of the first plate away from the heat storage component is flush with the body.

[0014] In this technical solution, the first plate is located within the receiving cavity, with the side of the first plate facing away from the heat storage component flush with the main body, allowing the receiving cavity to provide installation space for the first plate. Furthermore, placing the plate within the receiving cavity makes the overall structure of the tray more compact, shortening the distance between the first plate and the heat storage component, allowing the heat storage component to heat or cool the first plate more quickly. The fact that the side of the first plate facing away from the heat storage component is flush with the main body reduces the influence of the external environment on the temperature of the first plate, thereby improving the tray's insulation performance.

[0015] In one technical solution of this application, optionally, the body includes a frame, a connecting part, and a supporting part. One side of the connecting part is connected to the inner edge of the frame; the supporting part is connected to the other side of the connecting part, and the heat storage component is disposed on the supporting part and detachably connected to the supporting part.

[0016] In this technical solution, the main body includes a frame, a connecting part, and a supporting part. One side of the connecting part connects to the inner edge of the frame to achieve installation between the connecting part and the frame. The supporting part connects to the other side of the connecting part to achieve installation between the supporting part and the connecting part, thereby realizing the installation between the frame, the connecting part, and the supporting part. A heat storage component is disposed on the supporting part to achieve installation of the heat storage component, allowing the supporting part to support the heat storage component. The supporting part is detachable, allowing users to replace the supporting part according to their needs, and select a suitable heat storage component based on different food types and heat preservation requirements.

[0017] In one technical solution of this application, optionally, the distance between the connecting part and the heat storage component gradually decreases along one side of the inner edge of the frame to one side of the bearing part.

[0018] In this technical solution, the distance between the connecting part and the heat storage component gradually decreases from one side of the inner edge of the frame to the other side of the support part, so as to achieve the arrangement of the connecting part so that the connecting part is inclined relative to the support part. Since the heat storage component is installed on the support part, the inclined connecting part can limit the movement of the heat storage component and prevent the heat storage component from moving in the receiving cavity during the movement of the tray, thereby improving the stability of the heat storage component after installation.

[0019] In one technical solution of this application, optionally, the area of ​​the bearing portion facing the first plate is greater than or equal to the area of ​​the heat storage component facing away from the first plate.

[0020] In this technical solution, the area of ​​the bearing portion facing the first plate is greater than or equal to the area of ​​the heat storage component facing away from the first plate. Since the heat storage component is installed on the bearing portion, by limiting the area of ​​the bearing portion to be greater than or equal to the area of ​​the heat storage component facing away from the first plate, it is ensured that the heat storage component can be installed on the bearing portion, so that the heat storage component can fit snugly on the bearing portion after installation, thereby improving the stability of the heat storage component after installation and preventing the heat storage component from not fitting tightly to the bearing portion after installation.

[0021] In one technical solution of this application, optionally, the heat storage component is fitted to the support portion, and there is a gap between the side of the heat storage component away from the support portion and the first plate, so that the heat storage component can cool or heat the first plate through the gap.

[0022] In this technical solution, the heat storage component is fitted snugly to the support portion to facilitate its installation, improve its stability after installation, and prevent shaking or movement. A gap exists between the side of the heat storage component away from the support portion and the first plate, allowing the heat storage component to cool or heat the first plate. This gap prevents direct contact between the heat storage component and the first plate, thus preventing heavy objects on the first plate from compressing the heat storage component within the receiving cavity. The gap between the side of the heat storage component away from the support portion and the first plate also reduces thermal or cold stress damage to the first plate caused by temperature changes.

[0023] In one technical solution of this application, optionally, the frame extends in a direction away from the first plate, and there is a first distance between the outer edge of the frame and one side of the connecting part.

[0024] In this technical solution, the frame extends away from the first plate, and there is a first distance between the outer edge of the frame and one side of the connecting part. By extending the frame around its perimeter, the pallet can be more easily installed on other equipment, simplifying the installation process of the pallet and other equipment and reducing the installation difficulty.

[0025] In one technical solution of this application, the tray may optionally be a partition, a baking tray, a serving tray, a dinner plate, an ice cream roll machine, a cold plate, or a hot plate.

[0026] In this technical solution, the tray serves as a divider, allowing it to be installed and used within the refrigerator. When the tray functions as a divider, it is easy to remove. When the heat storage component includes phase change material (PCM), the use of PCM in household refrigerators is beneficial in terms of energy saving, cost reduction, and ensuring food preservation. PCM can suppress temperature drops in the refrigerator, for example, after the refrigerator door has been open for too long or after placing excessively hot food inside. The tray not only better maintains the ideal food preservation temperature but also intelligently "charges" the PCM during low-electricity periods and "activates" it during high-electricity periods. The tray can also be used as a baking tray in an oven. It can also be used as a serving tray for serving food, storing hand-held foods, or serving cold dishes. Furthermore, the tray can be used as a breakfast tray, allowing users to place all necessary breakfast items on the shelf, making them easily accessible from the refrigerator and immediately taken to the kitchen table. The tray can be used as a cold or hot tray, allowing it to be cooled in a refrigerator or heated to the appropriate temperature in an oven before use. The tray can also be used as an ice cream roll maker after being cooled in a refrigerator for a certain period.

[0027] In one technical solution of this application, optionally, the first plate body includes a metal plate and a covering layer, wherein the covering layer is coated on the metal plate; or the first plate body includes a stainless steel plate.

[0028] In this technical solution, the first plate body includes a metal plate and a covering layer. The covering layer is applied to the metal plate to form the first plate body. The covering layer isolates the metal plate from direct contact with the external environment, thereby preventing damage such as oxidation and corrosion, and extending the service life of the metal plate. The covering layer also enhances the wear resistance of the first plate body, making it less prone to damage during use. Furthermore, the first plate body is made of stainless steel, which has corrosion resistance, high strength, and load-bearing capacity, thus preventing deformation of the first plate body during use and further extending the service life of the pallet.

[0029] In one technical solution of this application, the first plate is optionally detachably connected to the main body.

[0030] In this technical solution, the first plate is detachably connected to the main body, allowing users to easily disassemble and clean the tray. Furthermore, this detachable connection facilitates user replacement of the heat exchange components according to usage and insulation requirements, thereby improving user convenience.

[0031] A second aspect of this application provides a household appliance that includes a tray as described in any of the above-described technical solutions. Therefore, this household appliance possesses all the beneficial effects of a tray, which will not be elaborated further here.

[0032] In one technical solution of this application, the household appliance may optionally include a refrigeration device or a heating device.

[0033] In this technical solution, when the household appliance is a refrigeration device, the tray can be used as a partition within the refrigeration device, facilitating storage of items. Users can also pre-cool the tray inside the refrigeration device and use it as a cold tray. Similarly, when the household appliance is a heating device, the tray can be used as a partition within the heating device, facilitating storage of items. Users can also pre-heat the tray inside the heating device and use it as a hot tray.

[0034] In one technical solution of this application, the household appliance is optionally detachably connected to the tray.

[0035] In this technical solution, the household appliance and the tray are detachably connected, facilitating the installation or removal of the tray from the appliance. This allows users to easily install the tray onto the appliance for use, and also allows it to be placed in the appliance for pre-cooling or pre-heating as needed, enabling it to be used as a cold or hot tray.

Detailed Implementation

[0043] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0045] The tray 100 and household appliances according to some embodiments of this application are described below with reference to Figures 1 to 4.

[0046] As shown in Figures 1, 2, and 3, in one embodiment of this application, a tray 100 is provided, including a body 102, a first plate 118, and a heat storage component 126. The body 102 has a receiving cavity 114 with an opening 116 on one side; the first plate 118 is located on one side of the body 102 and closes the opening 116 of the receiving cavity 114; the heat storage component 126 is disposed in the receiving cavity 114, located between the first plate 118 and the body 102; when the tray 100 moves from a first region to a second region, the heat storage component 126 can heat the first plate 118, and the temperature of the first region is greater than the temperature of the second region; or when the tray 100 moves from the first region to the second region, the heat storage component 126 can cool the first plate 118, and the temperature of the first region is less than the temperature of the second region.

[0047] In this embodiment, the tray 100 includes a body 102, a first plate 118, and a heat storage component 126. The body 102 has a receiving cavity 114 with an opening 116 on one side to facilitate the arrangement of the receiving cavity 114. The first plate 118 is located on one side of the body 102 and closes the opening 116 of the receiving cavity 114 to facilitate the arrangement of the first plate 118, allowing it to be installed together with the body 102. The heat storage component 126 is disposed in the receiving cavity 114, located between the first plate 118 and the body 102, so that the receiving cavity 114 can provide installation space for the heat storage component 126. Furthermore, the first plate 118 and the body 102 can also protect the heat storage component 126 from damage. When the tray 100 moves from the first area to the second area, the heat storage component 126 heats the first plate 118. The temperature of the first area is higher than the temperature of the second area. That is, the tray 100 moves from a higher-temperature first area to a lower-temperature second area. When the tray 100 is in the second area, the heat storage component 126 can heat the first plate 118, releasing the previously stored heat, thereby heating the items or food placed on the tray 100 and keeping them warm. When the tray 100 moves from the first area to the second area, the heat storage component 126 cools the first plate 118. The temperature of the first area is lower than the temperature of the second area. That is, the tray 100 moves from a lower-temperature first area to a higher-temperature second area. When the tray 100 is in the second area, the heat storage component 126 can cool the first plate 118, absorbing the surrounding heat, thereby cooling the items or food placed on the tray 100 and keeping them warm. This application provides a heat storage component 126 on the tray 100 to maintain temperature, thereby allowing the tray 100 to be pre-cooled or pre-heated according to the user's needs. This enables the tray 100 to be used for cooling or heating, thus keeping items or food placed on the tray 100 warm and improving user convenience.

[0048] Specifically, this application provides a heat storage component 126 on the tray 100, enabling the tray 100 to cool or heat according to usage requirements, thereby giving the tray 100 multiple functions.

[0049] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0050] The heat storage component 126 includes a phase change material that can release heat to heat the first plate 118 when the phase change material moves from the first region to the second region; or can absorb heat to cool the first plate 118 when the phase change material moves from the first region to the second region.

[0051] In this embodiment, the heat storage component 126 includes a phase change material. When the phase change material moves from the first region to the second region, it can release heat to heat the first plate 118. By providing the phase change material in the heat storage component 126, the tray 100 moves from a first region with a higher temperature to a second region with a lower temperature. When the tray 100 is in the second region, the phase change material will gradually change from its high-temperature phase to a low-temperature phase. During this process, the phase change material will release the heat it has previously absorbed, so that this heat is transferred to the first plate 118, thereby heating the first plate 118 so that the items or food placed on the tray 100 can maintain a certain temperature. When the phase change material moves from the first region to the second region, it can absorb heat to cool the first plate 118. The tray 100 moves from a lower temperature first region to a higher temperature second region. When the tray 100 is in the second region, the phase change material will gradually change from its low temperature phase to a high temperature phase. During this process, the phase change material will absorb heat from the surroundings, thereby cooling the first plate 118 so that the items or food placed on the tray 100 can maintain a certain temperature.

[0052] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0053] As shown in Figures 1, 2 and 3, the first plate 118 has a heat-insulating area 124, and the body 102 is recessed in a direction away from the first plate 118 to form a receiving cavity 114. The opening 116 of the receiving cavity 114 faces the first plate 118, and the heat storage component 126 corresponds to the heat-insulating area 124.

[0054] In this embodiment, the first plate 118 has a heat-insulating area 124, and the body 102 is recessed away from the first plate 118 to form a receiving cavity 114. The opening 116 of the receiving cavity 114 faces the first plate 118. The heat storage component 126 corresponds to the heat-insulating area 124, allowing the heat-insulating area 124 to receive the heat or cold transferred by the heat storage component 126 more concentratedly. The correspondence between the heat storage component 126 and the heat-insulating area 124 makes the heat transfer more precise and efficient. When the heat storage component 126 releases heat, it can directly heat the heat-insulating area 124, thereby heating the entire tray 100 and the food on it. When the heat storage component 126 absorbs heat, it can effectively reduce the temperature of the heat-insulating area 124, thereby maintaining the food at a low temperature.

[0055] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0056] As shown in Figures 1, 2 and 3, the first plate 118 is located in the receiving cavity 114, and the side of the first plate 118 facing away from the heat storage component 126 is flush with the body 102.

[0057] In this embodiment, the first plate 118 is located within the receiving cavity 114. The side of the first plate 118 facing away from the heat storage component 126 is flush with the body 102, allowing the receiving cavity 114 to provide installation space for the first plate 118. Furthermore, by also placing the plate within the receiving cavity 114, the overall structure of the tray 100 becomes more compact, shortening the distance between the first plate 118 and the heat storage component 126, allowing the heat storage component 126 to heat or cool the first plate 118 more quickly. The fact that the side of the first plate 118 facing away from the heat storage component 126 is flush with the body 102 reduces the influence of the external environment on the temperature of the first plate 118, thereby improving the thermal insulation performance of the tray 100.

[0058] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0059] As shown in Figures 1, 2, and 3, the main body 102 includes a frame 104, a connecting part 110, and a supporting part 112. One side of the connecting part 110 is connected to the inner edge 106 of the frame 104; the supporting part 112 is connected to the other side of the connecting part 110, and the heat storage component 126 is disposed on the supporting part 112 and is detachably connected to the supporting part 112.

[0060] In this embodiment, the main body 102 includes a frame 104, a connecting portion 110, and a supporting portion 112. One side of the connecting portion 110 is connected to the inner edge 106 of the frame 104 to achieve installation between the connecting portion 110 and the frame 104. The supporting portion 112 is connected to the other side of the connecting portion 110 to achieve installation between the supporting portion 112 and the connecting portion, thereby achieving installation between the frame 104, the connecting portion 110, and the supporting portion 112. A heat storage component 126 is disposed on the supporting portion 112 to achieve installation of the heat storage component 126, so that the supporting portion 112 can support the heat storage component 126. The supporting portion 112 is detachably connected so that the user can replace the supporting portion 112 according to usage needs, and a suitable heat storage component 126 can be selected according to different food types and heat preservation requirements.

[0061] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0062] As shown in Figures 1, 2 and 3, the distance between the connecting part 110 and the heat storage component 126 gradually decreases along one side of the inner edge 106 of the frame 104 to one side of the bearing part 112.

[0063] In this embodiment, the distance between the connecting part 110 and the heat storage component 126 gradually decreases along one side of the inner edge 106 of the frame 104 to one side of the support part 112, so as to achieve the arrangement of the connecting part 110 such that the connecting part 110 is inclined relative to the support part 112. Since the heat storage component 126 is installed on the support part 112, the inclined connecting part 110 can limit the movement of the heat storage component 126, and prevent the heat storage component 126 from moving in the receiving cavity 114 during the movement of the tray 100, thereby improving the stability of the heat storage component 126 after installation.

[0064] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0065] The area of ​​the bearing part 112 facing the first plate 118 is greater than or equal to the area of ​​the heat storage component 126 facing away from the first plate 118.

[0066] In this embodiment, the area of ​​the support portion 112 facing the first plate 118 is greater than or equal to the area of ​​the heat storage component 126 away from the first plate 118. Since the heat storage component 126 is mounted on the support portion 112, by limiting the area of ​​the support portion 112 to be greater than or equal to the area of ​​the heat storage component 126 away from the first plate 118, it is ensured that the heat storage component 126 can be mounted on the support portion 112, so that the heat storage component 126 can fit snugly on the support portion 112 after installation, thereby improving the stability of the heat storage component 126 after installation and preventing the heat storage component 126 from not fitting tightly to the support portion 112 after installation.

[0067] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0068] As shown in Figures 1, 2 and 3, the heat storage component 126 is fitted to the support portion 112. There is a gap 128 between the side of the heat storage component 126 away from the support portion 112 and the first plate 118. The heat storage component 126 can cool or heat the first plate 118 through the gap 128.

[0069] In this embodiment, the heat storage component 126 is fitted to the support portion 112 to facilitate its installation, improve its stability after installation, and prevent it from shaking or moving. A gap 128 exists between the side of the heat storage component 126 away from the support portion 112 and the first plate 118. The heat storage component 126 can cool or heat the first plate 118 through this gap. The gap 128 prevents direct contact between the heat storage component 126 and the first plate 118, thus preventing heavy objects on the first plate 118 from compressing the heat storage component 126 within the receiving cavity 114. The gap 128 between the side of the heat storage component 126 away from the support portion 112 and the first plate 118 also reduces thermal or cold stress damage to the first plate 118 caused by temperature changes.

[0070] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0071] As shown in Figures 1, 2 and 3, the frame 104 extends away from the first plate 118, and there is a first distance between the outer edge 108 of the frame 104 and one side of the connecting part 110.

[0072] In this embodiment, the frame 104 extends away from the first plate 118, and there is a first distance between the outer edge 108 of the frame 104 and one side of the connecting part 110. By extending the frame 104 around its perimeter, the tray 100 can be more easily installed on other equipment for use, simplifying the installation process of the tray 100 with other equipment and reducing the installation difficulty.

[0073] Specifically, in Figure 3, A represents the first distance.

[0074] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0075] Tray 100 can be used as a divider, baking tray, serving tray, dinner plate, ice cream roll machine, cold plate or hot plate.

[0076] In this embodiment, tray 100 serves as a partition, allowing it to be installed and used in the refrigerator. When tray 100 functions as a partition, it is easy to remove. When the heat storage component 126 includes a phase change material (PCM), the use of PCM in household refrigerators is beneficial in terms of energy saving, cost reduction, and ensuring food preservation. PCM can suppress temperature drops in the refrigerator, for example, after the refrigerator door has been open for an extended period or after placing excessively hot food inside. Tray 100 can better maintain ideal food preservation temperatures and can also intelligently "charge" the PCM during low-electricity periods and "activate" it during high-electricity periods. Tray 100 can also be used as a baking tray in an oven. Furthermore, tray 100 can be used as a serving tray, for serving food, storing hand-held food, or as a cold dish. Tray 100 can be used as a dinner plate, specifically a breakfast tray. The shelf allows users to place all necessary breakfast items on this tray, making them easy to remove from the refrigerator and immediately take to the kitchen table. Tray 100 can also be used as a cold or hot tray, meaning it can be cooled in the refrigerator or heated to the appropriate temperature in the oven. Furthermore, tray 100 can be used as an ice cream maker after being cooled in the refrigerator for a certain period.

[0077] Specifically, tray 100 can also be integrated into other devices across categories. The size of tray 100 allows it to fit various household appliances, such as refrigerators, ovens, freezers, or dishwashers, for easy cleaning after use. To optimally integrate or assemble tray 100 into these devices, additional connecting parts 110 can be provided for assembly. The heat storage component 126 is a replaceable part on tray 100, allowing it to be replaced according to the user's insulation needs. For example, it can be used for faster pre-cooling or pre-heating in refrigerators or ovens, or for different heat storage components 126 for cooling and heating purposes.

[0078] Specifically, tray 100 can also be used as an ice cream roll making machine, allowing the tray 100 to produce more ice cream rolls before reaching the ideal temperature.

[0079] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0080] The first plate 118 includes a metal plate 120 and a cover layer 122, the cover layer 122 being coated on the metal plate 120; or the first plate 118 includes a stainless steel plate.

[0081] In this embodiment, the first plate 118 includes a metal plate 120 and a covering layer 122. The covering layer 122 is applied to the metal plate 120 to form the first plate 118. The covering layer 122 can isolate the metal plate 120 from direct contact with the external environment, thereby preventing the metal plate 120 from being damaged by oxidation, corrosion, etc., and thus extending the service life of the metal plate 120. The covering layer 122 can also enhance the wear resistance of the first plate 118, making it less prone to damage during use. The first plate 118 is made of stainless steel, which has corrosion resistance, high strength, and load-bearing capacity, thus preventing deformation of the first plate 118 during use and further extending the service life of the pallet 100.

[0082] As shown in Figure 4, the first plate 118 includes a metal plate 120 and a cover layer 122, with the cover layer 122 coated on the metal plate 120.

[0083] Specifically, the cost of the tray 100 mainly lies in the choice of materials. The first plate 118 can be made of a thick stainless steel plate with a high-quality finish or a thin metal plate 120 painted. Similarly, the choice of the heat storage component 126 is also important. Compared with complex chemical and physical methods, choosing water and a base solution as the heat storage component 126 can save costs. On the other hand, this method has higher thermal efficiency.

[0084] This embodiment provides a tray 100, which, in addition to the technical features of the above embodiments, further includes the following technical features.

[0085] The first plate 118 is detachably connected to the main body 102.

[0086] In this embodiment, the first plate 118 is detachably connected to the main body 102, allowing the user to easily disassemble and clean the tray 100. Furthermore, the detachable connection between the first plate 118 and the main body 102 facilitates the replacement of heat exchange components according to usage and insulation requirements, thereby improving user convenience.

[0087] Specifically, the body 102 is provided with a heat storage component 126, which can isolate the bottom area of ​​the tray 100 to improve the thermal conductivity of the top of the tray 100. The heat storage component 126 allows for extending the food preservation temperature on the tray 100, suitable for food on the tray 100 or for making ice cream rolls, for example, using PCM (phase change material, such as propylene glycol), water-based solutions, or clay. In medical applications, many hot and cold compresses are achieved by dissolving salt in water; as the salt decomposes, heat is released in an exothermic reaction or absorbed in an endothermic reaction, which is the same function as the heat storage component 126 in this application. The first plate 118 is capable of transferring the temperature of the heat storage component 126 to the food, and the material of the first plate 118 meets food safety requirements.

[0088] Specifically, the tray 100 of this application can extend the freshness of the food due to the heat preservation properties of the heat storage component 126.

[0089] Specifically, the heat storage component 126 is used as a cooling or heating battery, thereby maintaining the conduction temperature through thermal conduction.

[0090] Specifically, it is useful to temporarily store foods that may not be served immediately, such as appetizers, hand-held foods, or cold cuts, in a refrigerator or oven. The choice between keeping the food warm or cool depends on its intended use, and the same tray 100 can be used for both storage and serving. Furthermore, the tray 100 is sized to match refrigerators, ovens, and other appliances, making the preparation, storage, and serving of such foods more convenient, quick, and easy. For example, the tray 100 of this application can be used to prepare, store, and serve such foods when hosting a dinner party.
