[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The embodiment of the present invention provides a constant temperature heating plate, including: a heat-conducting plate 100 and a heating bottom plate 200, the structure of which can refer to Figure 1 As shown, the heat-conducting dinner plate 100 is provided with a sealed cavity 113 for placing the phase change material; the heat-conducting dinner plate 100 is arranged on the heating bottom plate 200, and the heating bottom plate 200 can provide heat for the heat-conducting dinner plate 100 when the temperature of the heat-conducting dinner plate 100 is lower than the preset temperature. Specifically, the heating bottom plate 200 can obtain the temperature of the heat-conducting dinner plate 100 through a sensor.

[0037] It can be seen from the above technical solutions that the constant temperature heating plate provided in the embodiment of the present invention utilizes the characteristics of the phase change material in the sealed cavity 113 to store and release heat, and can heat and keep the food in the heat-conducting plate 100 warm for a certain period of time; further, when the temperature of the heat-conducting plate 100 is lower than the preset temperature, the heating base 200 intervenes to provide heat, which can increase the constant temperature time of the food in the plate, improve the dining experience, and ensure healthy dining.

[0038] In some embodiments provided in this solution, the heating chassis 200 includes: a heating chassis housing 210 and a heating temperature control system, the structure of which can refer to Figure 4 As shown; wherein, the heating chassis shell 210 is made of low thermal conductivity material, which can be wood, plastic, etc., to play a role in heat preservation.

[0039] In some embodiments provided in this solution, the heating temperature control system includes: a power supply unit and a heating temperature control unit; the power supply unit can provide electric energy to the heating temperature control unit; the heating temperature control unit includes: a heating film, a heat conducting plate 240 and a circuit system, and its structure can refer to Figure 4 As shown, the heating film can heat the heat-conducting plate 240, the heat-conducting plate 240 is in contact with the bottom of the heat-conducting dinner plate 100, and the circuit system is connected between the power supply unit and the heating film. The heating film can be a flexible PI or graphene material, the input power of the heating film can be controlled, and the heating film heats the heat-conducting plate 240.

[0040] In some embodiments of the present invention, the heat-conducting dining tray 100 can be separated from the heating bottom tray 200, and its structure can refer to Figure 1 As shown, a groove matching the heat-conducting plate 100 can be specifically provided on the top of the heating bottom plate 200. This arrangement, on the one hand, facilitates the cleaning and disinfection of the heat-conducting plate 100; on the other hand, the heat-conducting plate 100 can absorb heat before use, such as being placed in a high-temperature disinfection cabinet, and heat storage of the phase change material can be completed during high-temperature disinfection, which is convenient to use and improves efficiency.

[0041] When using the constant temperature heating plate containing phase change material in this solution, the heat-conducting plate 100 is first disinfected in a high-temperature disinfection cabinet above 120°C, and heat is stored at the same time. When the heat-conducting plate 100 is served on the table, the phase change material can maintain the constant temperature of the heat-conducting plate 100 through phase change heat dissipation for a certain period of time. When the heat storage of the phase change material is not enough to support the constant temperature of the heat-conducting plate 100, the heating bottom plate 200 starts heating the heating film. The active and passive combined heating of this solution can keep the plate at a constant temperature for a longer time, saving the power of the power supply unit.

[0042] In some embodiments provided in this solution, the heat-conducting dinner plate 100 includes: a ceramic body 111 and a base 112, and its structure can refer to Figure 2As shown; wherein, the material of the base 112 is determined by the composition of the phase change material, which can be metal, plastic, ceramic, etc.; the base 112 is outsourced to the bottom of the ceramic body 111, and a sealed cavity 113 is formed between the ceramic body 111 and the base 112. That is, the body of the thermally conductive dinner plate 100 can be made of ceramic material, and the bottom of the ceramic dinner plate is outsourced to a thermally conductive material combination, and the sealed cavity 113 between them can be injected with a 60-80°C phase change material. The ceramic body 111 and the base 112 are a composite integrated structure. Before use, the thermally conductive dinner plate 100 is placed in a high-temperature disinfection cabinet, and the phase change material can absorb heat and store heat. During use, the phase change material releases heat and transfers it to the dinner plate, so that the thermally conductive dinner plate 100 is kept at a constant temperature below 60°C to prevent scalding safety temperature, while ensuring that the dishes on the dinner plate are at 40-50°C.

[0043] In some embodiments provided by the present invention, the heat-conducting dinner plate 100 is made of metal, and the inner wall 122 and the outer wall 123 of the heat-conducting dinner plate 100 are plated with ceramic material.

That is, the heat-conducting dinner plate 100 can also be made of metal, and the outer wall bottom 121 is not processed in any way, retaining the high thermal conductivity of metal. Except for the bottom of the dinner plate, the bottom of the inner wall of the dinner plate, the inner wall around and the outer wall around 123 are plated with ceramic material.

[0044] In some embodiments provided by the present invention, the heating base 200 further includes: a heat insulating ring 220, the structure of which can refer to Figure 4 As shown in the figure, the heat insulating ring 220 is located between the outer wall around the heat conductive dinner plate 100 and the heating bottom plate shell 210, and the heat insulating ring 220 is made of a low heat conductive heat insulating material. The heat insulating ring 220 is made of a low heat conductive heat insulating material, such as low heat conductive rubber, low heat conductive plastic, low heat conductive rubber-plastic material, etc., and is located between the outer wall around the heat conductive dinner plate 100 and the heating bottom plate shell 210, tightly wrapping the heat conductive dinner plate 100 to reduce heat loss.

[0045] In some embodiments provided by the present solution, the circuit system includes: a temperature sensor; the temperature sensor is embedded in the heat insulation ring 220. By embedding the temperature sensor in the heat insulation ring 220, the present solution does not affect the cleaning and disinfection of the heat-conducting dinner plate 100.

[0046] In some embodiments provided by the present solution, temperature sensors are respectively embedded in the multiple side walls of the heat insulation ring 220. Specifically, four temperature sensors can be embedded in the upper part of the side wall of the heat insulation ring 220, and the four sensors can respectively monitor the temperature of the side walls around the heat-conducting dinner plate 100. When any temperature value is lower than the preset temperature, the heating film is activated to heat the dinner plate to ensure a constant temperature.

[0047] In some embodiments provided by the present solution, the temperature sensor is a short-range infrared temperature sensor, so as to accurately obtain the temperature of the thermally conductive dinner plate 100 .

[0048] In some embodiments provided by this solution, the circuit system includes: a temperature sensor and a control system; the control system can adjust the heating rate and temperature according to the feedback of the temperature sensor. According to the characteristics of the heating film, its stability and safety under different input powers are ensured, and the heating rate and temperature are adjusted to be constant through the feedback of the temperature sensor and the PID temperature control.

[0049] In some embodiments provided by the present invention, the heating and temperature control system further includes: a flexible heat conducting mechanism 230, the structure of which can refer to Figure 4 As shown; wherein, the flexible heat conduction mechanism 230 is arranged between the heat conduction plate 240 and the heat conduction dinner plate 100. The heat conduction plate transfers heat to the dinner plate without phase change material or containing phase change material through the flexible high heat conduction material or high heat conduction liquid bag to maintain the constant temperature of the dinner plate. A layer of flexible high heat conduction material or high heat conduction liquid bag is arranged between the bottom of the dinner plate and the heat conduction plate. When the bottom of the dinner plate is not a complete plane but has grids, the heat conduction contact area of ​​the dinner plate can be increased to improve the heat conduction efficiency.

[0050] In some embodiments provided by the present solution, the power supply unit includes: a battery pack, a sensor and a battery management system; wherein the battery pack is used to power the heating film, the sensor is used to collect the battery pack, and the battery management system can monitor the status of the battery pack according to the status data collected by the sensor. Specifically, the battery pack is a low-resistance rechargeable high-power battery, and the battery pack powers the heating film. The battery management system monitors the status of the battery, including voltage, current, and temperature, to ensure the safety and efficiency of the battery. The sensor is used to collect this data to assist the battery management system in making corresponding management decisions. The structural design with its own battery can be used in any restaurant, and the dining table does not need to be equipped with a power supply.

[0051] In some embodiments provided by the present invention, the heat-conducting dinner plate 100 is in a multi-grid form, and can hold multiple dishes according to the needs of the user, such as a nine-grid or five-grid grid. Figure 5 and Figure 6 shown.

[0052] The present invention is further described below in conjunction with the embodiments:

[0053] A constant temperature heating dinner plate is composed of a heat-conducting dinner plate 100 and a heating bottom plate 200, which are separate structures.

[0054] The heat-conducting dinner plate 100 is in a multi-grid form, and can hold multiple dishes according to the needs of the user, such as a nine-grid or a five-grid. Figure 5 and Figure 6As shown. The materials of the dinner plate include ceramic, metal, glass, plastic, and composite materials. The bottom of the dinner plate has good thermal conductivity, and the side walls around the dinner plate have good thermal insulation performance. The bottom of the dinner plate can be formed into a cavity by using a composite process of different materials, and a phase change material can be injected into the cavity to improve thermal efficiency through the energy storage characteristics of the phase change material.

[0055] The ceramic-metal composite integrated dinner plate is composed of a ceramic body 111 and a base 112. Figure 2 As shown. A sealed cavity 113 is formed between the base and the ceramic, and a 60-80°C phase change material can be injected into the cavity. When the plate is placed in a high-temperature disinfection cabinet, the phase change material can absorb heat and store heat. When the plate is used, the phase change material releases heat and transfers it to the plate.

[0056] Metal body plated ceramic dinner plate, such as Figure 3 As shown, the dinner plate body can also be made of metal, the outer wall bottom 121 is not processed in any way, retaining the high thermal conductivity of the metal, and the inner wall 122 and the outer wall 123 of the dinner plate are plated with ceramic material.

[0057] The heating chassis is composed of a shell, a heating temperature control system, and a heat insulation ring 220. Figure 4 As shown. The material of the heat insulating ring 220 is a low thermal conductivity insulation material, and is located between the heat conductive dinner plate 100 and the heating bottom plate shell 210. The shell 210 is made of a low thermal conductivity insulation material, such as wood, low thermal conductivity plastic, etc. The shape of one side of the heat insulating ring 230 is adapted to the shape of the outer wall of the dinner plate, and is in close contact with the outer wall of the heat conductive dinner plate. The other side is in a vertical shape and is in close contact with the side wall of the heating bottom plate. The bottom end wraps the heat conductive plate 240 to form a sealed structure. A flexible high thermal conductivity material or a high thermal conductivity liquid bag (that is, the aforementioned flexible heat conductive mechanism 230) that can be arbitrarily shaped is placed on the heat conductive plate. When the bottom of the dinner plate is not a complete plane, the flexible high thermal conductivity material or the high thermal conductivity liquid bag can be arbitrarily deformed according to the shape of the bottom of the dish. Under the gravity of the dinner plate, the bottom of the dinner plate is in close contact with the high thermal conductivity material, ensuring that most of the heat of the heat conductive plate is transferred to the dinner plate, reducing heat loss.

[0058] The heating temperature control system includes a power supply unit and a heating temperature control unit.

[0059] The power supply unit mainly includes battery packs, sensors and battery management systems. The battery pack is a low-resistance, rechargeable, high-power battery that supplies power to the heating film. The battery management system monitors the status of the battery, including voltage, current and temperature, to ensure the safety and efficiency of the battery. Sensors are used to collect this data to assist the battery management system in making corresponding management decisions.

[0060] The heating and temperature control unit includes a heating film, a heat conducting plate, a flexible high thermal conductivity material or a high thermal conductivity liquid package, and a circuit system. The heating film can be a flexible PI or graphene material. The input power of the heating film can be controlled. The heating film heats the heat conducting plate. The heat conducting plate transfers heat to the dinner plate without phase change material or containing phase change material through the flexible high thermal conductivity material or the high thermal conductivity liquid package to maintain the constant temperature of the dinner plate. A layer of flexible high thermal conductivity material or high thermal conductivity liquid package is arranged between the bottom of the dinner plate and the heat conducting plate. When the bottom of the dinner plate is not a complete plane but has grids, the thermal contact area of ​​the dinner plate can be increased to improve the thermal conductivity efficiency. The circuit includes a temperature sensor and a control system. According to the characteristics of the heating film, it ensures its stability and safety under different input powers, and adjusts the heating rate and temperature to be constant through temperature sensor feedback and PID temperature control.

[0061] This solution has the following features:

[0062] 1. When the phase change material dinner plate and the heating base plate are used in combination, the characteristics of the phase change material and the heating film can be used to realize a combined active and passive heating method, thereby increasing the constant temperature time of the dinner plate and saving electricity.

[0063] 2. High temperature disinfection and heat absorption: The plates are first placed in a high temperature disinfection cabinet, and the temperature is set to above 120°C. During the plate disinfection process, the phase change material at the bottom of the plate changes from solid to liquid at high temperature, absorbing a large amount of heat and storing it. The phase change temperature of the phase change material can be set at 60-80 degrees, and the latent heat is greater than 200kJ / kg.

[0064] 3. Phase change heat dissipation: When the plate is served, the phase change material begins to release heat through the phase change process. In this process, the material changes from liquid to solid, releasing the previously stored heat, thereby maintaining the temperature of the plate.

[0065] 4. Infrared temperature sensor: Four temperature sensors are embedded in the upper part of the side wall of the insulation ring. The four sensors can monitor the temperature of the side walls around the plate respectively. The temperature sensor is a short-range infrared temperature sensor, which is embedded in the insulation ring and does not affect the cleaning and disinfection of the plate.

[0066] 5. Heating film heating: The temperature sensor monitors the temperature of the side walls of the four plates. When any temperature value is lower than the preset temperature, the heating film heating is started. The heating film is an active heating technology that converts electrical energy into thermal energy. The heating film heats the heat conducting plate, and the heat conducting plate transfers the heat to the phase change material at the bottom of the plate, continuously heating the plate to ensure a constant temperature of the plate.

[0067] 6. Save electricity: Since phase change materials can store and release a large amount of heat, the heat released by the phase change material can maintain the constant temperature of the plate within the first 30 to 40 minutes of the user's meal. When the heat stored in the phase change material is not enough to maintain the constant temperature of the plate, the heating film is started to heat. This combination of active and passive heating method can not only extend the constant temperature time of the plate to more than 2 hours, but also save electricity.

[0068] Compared with the prior art, the present invention has the following advantages:

[0069] 1. Utilize the thermal conductivity of different materials and combine them with phase change materials to design heat-conducting dinner plates to improve heating efficiency and constant temperature duration;

[0070] 2. Use high temperature disinfection of the dinner plates to allow the phase change material to absorb heat in advance, so that the dinner plates can be heated and kept warm when used;

[0071] 3. Design a heating chassis that uses a combination of a shell, a heating temperature control system, and a heat insulation ring to keep the temperature of a plate containing multiple dishes constant on a dining table without power supply, thus avoiding discomfort caused by cold food;

[0072] 4. The insulation ring is made of low thermal conductivity insulation material and is located between the outer wall around the dinner plate and the heating base plate, tightly wrapping the dinner plate to reduce heat loss.

[0073] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0074] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
