Technical Field
[0001] The utility model relates to the technical field of heat-insulating dinner plates, in particular to a multi-layer grooved heat-insulating dinner plate. Background Art
[0002] In the catering industry and some scenarios where food needs to be kept warm, the heat preservation performance of the plate is an important consideration.
[0003] Traditional dinner plates have many shortcomings in terms of heat preservation. On the one hand, most dinner plates lack effective insulation structure and have limited insulation effect. Heat can easily be quickly dissipated from the inside of the dinner plate to the surrounding environment through air convection and heat conduction, causing the food to cool down in a short time, affecting the taste and quality of the food.
[0004] On the other hand, traditional dinner plates need to be kept warm in a water bath or other heat source environment, resulting in energy loss. Traditional dinner plates require external heat sources for insulation, which is inconvenient to turn around and limits the flexibility and convenience of using the dinner plates. To solve the above problems, we propose a multi-layer grooved insulation dinner plate. Utility Model Content

By providing the energy storage layer, it can provide heat and effectively keep warm, which is convenient for turnover and effectively reduces energy consumption, avoiding the problem that traditional dinner plates require external heat sources for insulation and are inconvenient for turnover.
[0006] Preferably, the base of the dinner plate is a grooved one-piece food-grade stainless steel, the upper surface of the dinner plate is a grooved one-piece food-grade stainless steel, and the base of the dinner plate and the upper surface of the dinner plate are seamlessly welded into one body. By seamlessly welding the base of the dinner plate and the upper surface of the dinner plate into one body, the structural stability of the dinner plate is ensured.
[0007] Preferably, the insulation layer includes a fixed plate, the outer side of the fixed plate is fixedly connected to a core material, the side of the core material away from the fixed plate is fixedly connected to a barrier film, the outer side of the fixed plate is fixedly connected to an isolation plate, the outer side of the isolation plate is fixedly connected to the outer side of the core material, the side of the isolation plate away from the fixed plate is fixedly connected to the side of the barrier film close to the core material, the outer side of the barrier film is fixedly connected to an adhesive layer, and insulation is performed by providing an insulation layer, and the insulation layer serves as a groove-type integrated vacuum insulation panel, which effectively prevents heat from being lost from the inside of the plate to the outside by reducing air convection and heat conduction, thereby maintaining the temperature of the food.
[0008] The beneficial effects of the utility model are as follows:
[0009] 1. This utility model provides heat preservation by providing an insulation layer. The insulation layer is a grooved, integrated vacuum insulation panel.

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications. Example
[0017] See also Figures 1-4 The utility model provides a technical solution: a multi-layer grooved thermal insulation dinner plate, comprising a dinner plate base 1, the top of the dinner plate base 1 is fixedly connected to the dinner plate upper surface layer 4; an insulation layer 2, the insulation layer 2 is used to keep the food warm, the bottom of the insulation layer 2 is fixedly connected to the bottom of the inner cavity of the dinner plate base 1, the insulation layer 2 is a groove-type integrated vacuum insulation panel; an energy storage layer 3, the bottom of the energy storage layer 3 is fixedly connected to the bottom of the inner cavity of the insulation layer 2, and the bottom of the inner cavity of the energy storage layer 3 is fixedly connected to the bottom of the upper surface layer 4 of the dinner plate. When in use, the dinner plate base 1 and the dinner plate upper surface layer 4 are made of S31603 stainless steel, and the insulation layer 2 adopts a groove-type integrated vacuum insulation panel to reduce heat loss. The vacuum insulation panel can also be a rectangular groove-integrated shape or a column-integrated shape, etc. The energy storage layer 3 is a phase change material, which is a green, environmentally friendly and recyclable energy storage material. Bio-based polymer phase change material can be used. The energy storage layer 3 can absorb and release heat to further maintain the temperature of the food.
[0018] The bottom support 1 of the dinner plate is a grooved one-piece food-grade stainless steel, and the upper surface layer 4 of the dinner plate is a grooved one-piece food-grade stainless steel. The bottom support 1 of the dinner plate and the upper surface layer 4 of the dinner plate are seamlessly welded into one body. When in use, the bottom support 1 of the dinner plate and the upper surface layer 4 of the dinner plate are seamlessly welded into one body. The vacuum insulation panel insulates the dinner plate to prevent energy loss, and the phase change material stores the energy in the dinner plate. The energy stored in the phase change material continuously heats the dinner plate, ensuring that the dinner plate still maintains a certain temperature when there is no power supply or other heat source.
[0019] The insulation layer 2 includes a fixing plate 21, the outer side of the fixing plate 21 is fixedly connected to a core material 22, the side of the core material 22 away from the fixing plate 21 is fixedly connected to a barrier film 23, the outer side of the fixing plate 21 is fixedly connected to an isolation plate 24, the outer side of the isolation plate 24 is fixedly connected to the outer side of the core material 22, the side of the isolation plate 24 away from the fixing plate 21 is fixedly connected to the side of the barrier film 23 close to the core material 22, and the outer side of the barrier film 23 is fixedly connected to an adhesive layer 25. When in use, the insulation layer 2 is fixed to the dining plate base 1 by the adhesive layer 25. The barrier film 23 cooperates with the core material 22 so that the interior of the insulation layer 2 is in a vacuum state and there is no gas flow, which reduces the heat transfer path such as heat convection and enhances the insulation effect of the lunch box. The isolation plate 24 on the fixing plate 21 divides the interior of the insulation layer 2 into multiple spaces. When the barrier film 23 is damaged, air will only flow in the damaged part, reducing the impact of the damage of the barrier film 23 on the insulation layer 2.
[0020] Working principle:
[0021] When in use, the plate base 1 and the plate upper surface 4 are seamlessly welded into one body. The insulation layer 2 uses a grooved integral vacuum insulation panel to effectively prevent heat loss from the inside of the plate to the outside by reducing air convection and heat conduction, thereby maintaining the temperature of the food. The energy storage layer 3 is a phase change material that stores energy in the plate. The energy stored in the phase change material continuously heats the plate, ensuring that the plate maintains a certain temperature even without power or other heat sources.
[0022] When in use, the insulation layer 2 is fixed to the bottom tray 1 of the dining plate by the adhesive layer 25. The barrier film 23 cooperates with the core material 22 to make the interior of the insulation layer 2 in a vacuum state. There is no gas flow, which reduces the heat transfer path such as heat convection and enhances the insulation effect of the lunch box. The isolation plate 24 on the fixed plate 21 divides the interior of the insulation layer 2 into multiple spaces. When the barrier film 23 is damaged, air will only flow in the damaged part, reducing the impact of the damage of the barrier film 23 on the insulation layer 2.
