[0035] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] Example 1

[0037] like Figure 1 and Figure 2 A specific embodiment of the food insulation plate shown is a food insulation plate suitable for keeping food warm. The food insulation plate includes: a heating body 1, an air outlet 2 and a control module. The heating body 1 includes a heating component 11 and a heating area 12. The heating area 12 is suitable for placing food to be kept warm. The heating component 11 is arranged at the bottom of the heating area 12, and the air outlet 2 is arranged on the side of the heating area 12. The air outlet 2 is connected to the heating component 11 and the heating area 12 so that the hot air formed when the heating component 11 is heated enters the heating area 12 through the air outlet 2. The control module is connected to the heating component 11, and the control module is suitable for controlling the heating component 11 to heat the heating area 12.

[0038] The aforementioned food insulation board, also known as a warming board, can be used to keep prepared meals warm. For example, if a meal is prepared but the diners are unable to eat immediately due to an emergency, placing the meal on the food insulation board to keep it warm will not affect the diners' ability to continue eating. The heating area 12 is used to place food to be heated, such as prepared meals.

[0039] The heating element 11 can be a resistance wire heater, an electric heating plate heater, or any other heating method, as long as it can generate heat, allowing the heating element 11 to function as a heat source. The heating element 11 is positioned below the heating area 12. When the heating element 11 heats, the heat is transferred to the heating area 12, thereby keeping the food placed in the heating area 12 warm. In this case, the heating element 11 can directly heat the bottom of the tableware containing the food placed in the heating area 12, thereby increasing the temperature of the tableware, which can then heat the food contained in the tableware, achieving heat preservation.

[0040] The air outlet 2 is disposed on the side of the heating area 12. When the heating assembly 11 is turned on, the ambient temperature rises, forming a hot air flow. The hot air flows into the air outlet 2 and then into the heating area 12, thereby heating the heating area 12 from the side. Therefore, both the bottom and the side of the heating area 12 can heat the food placed in the heating area 12, thereby ensuring a uniform temperature of the food to be kept warm, and improving the nutrition and taste of the food.

[0041] Furthermore, if Figure 2 and Figure 3 As shown, the food insulation plate further includes a boss 3 , which is arranged around the heating area 12 , and a plurality of air outlets 2 are circumferentially arranged on the boss 3 .

[0042] The above-mentioned boss 3 can form an annular frame structure. Among them, an air duct is set in the boss 3, one end of the air duct is connected to the heating component 11, and the other end of the air duct is connected to the air outlet 2, and the air outlet 2 is opened on the inner side of the boss 3 facing the heating area 12. The shape of the heating area 12 can be rectangular, and the boss 3 can be a rectangular annular plate structure. The heating area 12 is located in the boss 3. When multiple air outlets 2 are evenly distributed along the side wall of the boss 3 set in the heating area 12, and two adjacent air outlets 2 are spaced apart from each other by a certain distance, hot air can be formed around the heating area 12, and then the hot air can move to the top of the heating area 12, so that the heat preservation effect of the heating area 12 will be better.

[0043] In addition, the boss 3 is arranged around the heating area 12, which further prevents heat loss.

[0044] Furthermore, when the heat preservation function of the food insulation board is not needed, if the boss 3 can be stored, the space occupied by the food insulation board can be reduced. To solve this problem, the food insulation board also includes a lifting assembly, which is connected to the boss 3 so that the lifting assembly drives the boss 3 to rise or fall. When the lifting assembly drives the boss 3 to rise, the boss 3 surrounds the outer periphery of the heating area 12, allowing hot air to enter the heating area 12 from the air outlet 2 provided on the boss 3; when the lifting assembly drives the boss 3 to fall, the position of the boss 3 is lowered, thereby facilitating the storage of the insulation board.

[0045] The lifting assembly can be raised and lowered in response to a signal indicating the machine is turned on or off, or it can be manually raised and lowered using a spring-loaded mechanism. For example, the lifting assembly can include a cylinder that is communicatively connected to the control module. When the heating assembly 11 is turned on to heat, the lifting assembly can also be turned on simultaneously, causing the boss 3 to rise. The lifting assembly can also include a drive motor, a gear, and a rack. The drive motor drives the gear, which in turn drives the rack, which is connected to the boss 3.

[0046] In addition, the boss 3 can also be raised and lowered by adopting a structure that is engaged with the base 13. Specifically, a chute extending upward is provided within the base 13, and a serrated structure is provided on the chute. The serrated structure is also provided on the boss 3, so that the boss 3 and the chute cooperate with each other to form a lifting assembly. When the boss 3 needs to be raised, the boss 3 can be pulled upward, or when the boss 3 needs to be lowered, the boss 3 can be pressed. By setting such a lifting method for the boss 3, it can be operated manually or by a gear assembly and a motor. This is a prior art and does not need to be elaborated on.

[0047] Since the boss 3 can be raised and lowered, the height of the boss 3 is lower than that of the heating body 1. When working, the boss 3 can realize side air outlet, which can well solve the disadvantage that the current warming plate only transfers heat from the bottom when heating food, that is, the food is cold on the top and hot on the bottom, affecting the taste.

[0048] Further, continue to combine Figure 2 As shown, the heating body 1 also includes a base 13, the boss 3 and the heating area 12 are respectively arranged on the top surface of the base 13, a heating cavity 14 is formed in the base 13, the heating component 11 is arranged in the heating cavity 14, and the air outlet 2 is connected to the heating cavity 14.

[0049] The above-mentioned base 13 has a top wall, side walls and a bottom wall, which enclose a heating chamber 14. The heating component 11 is arranged in the heating chamber 14. When the heating component 11 starts to heat, hot air flows in the heating chamber 14, and the heating area 12 is arranged on the top surface of the base 13. The top surface of the base 13 is located above the heating area 12. Therefore, the heating chamber 14 can form a heating source to better heat the heating area 12.

[0050] Furthermore, the base 13 includes: a bottom platform and a top platform, the bottom platform forms a heating cavity 14, and the inner top of the heating cavity 14 is provided with a heating component 11; the top platform is arranged on the bottom platform, the top platform protrudes from the bottom platform, and the top platform forms a heating area 12; wherein, the edge of the top platform and the edge of the corresponding side of the bottom platform form a gap to accommodate the boss 3, so that the boss 3 is arranged around the top platform.

[0051] The above-mentioned base may include a base top and a base side. The base side may be an annular plate. The base top and the base side enclose a heating chamber 14, so that the base can be buckled on the table, and the base can also form a supporting function. The heating component 11 is arranged in the heating chamber 14, and the heating component 11 can be installed on one side of the base top located at the heating chamber 14, while the top platform is arranged on the side of the base top opposite to the heating component 11. The top platform is arranged upward, so that after the heating component 11 starts heating, the heat can be quickly transferred to the top platform through the base top, thereby quickly heating the heating area 12. The boss 3 may be an annular plate structure, and the boss 3 has a certain thickness, so that when the boss 3 is raised, it can be arranged around the top platform, so that the heating area 12 of the top platform is located in the surrounding area of ​​the boss 3, so that hot air can enter the heating area 12 through the air outlet 2 on the boss 3.

[0052] Furthermore, if Figure 3 As shown, a bottom plate 131 is provided at the bottom of the base, and the bottom plate 131 is suitable for sealing the heating cavity 14 to prevent heat loss, so as to form a better heating effect for the heating area 12.

[0053] Specifically, the heating chamber 14 can be a rectangular cavity, the bottom plate 131 can cover the heating chamber 14, and the bottom plate 131 and the heating chamber 14 can be sealed, so that the heat of the hot air in the heating chamber 14 will not dissipate out of the heating chamber 14, thereby improving thermal efficiency.

[0054] Furthermore, the height of the boss 3 is lower than that of the top platform, so that the boss 3 can be lowered to the bottom of the top platform, making it easier to store the food insulation plate.

[0055] Above-mentioned boss 3 can be accommodated in the marginal space around top platform, and is convenient to accommodate heat preservation board like this.Certainly, the height of boss 3 also can be flush with the height of top platform or higher than the height of top platform.

[0056] Among them, continue to combine Figure 2 and Figure 4 As shown, a control box 4 is provided on one side outer wall of the base 13, and the control module is provided in the control box 4, so that the control box 4 can not only accommodate the control module, but also serve as a handle for the food insulation plate, which is convenient for taking and placing. The control module may include temperature regulation, heat dissipation functions, etc. For example, a thermometer may be provided in the heating area 12, and the thermometer is used to detect the temperature in the heating area 12. When the temperature exceeds the preset temperature, the heating component 11 is controlled to be turned off or part of the heating function of the heating component 11 is turned off, or the heating gear of the heating component 11 is set, and the selection of the heating gear is controlled by the temperature. Or when the heating is completed, the blowing component 15 is controlled to be turned on so that the food insulation plate can dissipate heat more quickly.

[0057] Furthermore, the food insulation plate further includes a blowing assembly 15, which is connected to a control module. The control module is adapted to control the blowing assembly 15 to blow hot air generated by the heating assembly 11 toward the vents or to control the blowing assembly 15 to dissipate heat from the heating area 12. The blowing assembly 15 may include a fan, which is communicatively connected to the control module, and the control module can control the fan to be turned on or off.

[0058] Furthermore, if Figure 5 As shown, the heating component 11 is formed with two heating modules, and the blowing component 15 is arranged between the two heating modules, wherein the two heating modules are a first heating module 111 and a second heating module 112, respectively. The first heating module 111 and the second heating module 112 can be the same or different. When the blowing component 15 is arranged between the first heating module 111 and the second heating module 112, the hot air from the heating chamber 14 can enter the multiple air outlets 2 evenly.

[0059] It can be understood that the working principle of the food insulation board is: before starting up, the whole machine is in Figure 6 In the state shown, the boss 3 is lowered to the bottom and flush with the heating area 12 for easy storage. When the machine is turned on, the boss 3 automatically rises, and the fan at the bottom cooperates with the heating component 11 to discharge hot air. The food on the heating area 12 can be quickly heated under the dual effects of bottom heating and hot air discharge from the side air outlet 2, and the bottom and upper surface of the food can be heated evenly.

[0060] It can be understood that the food insulation plate can be a vegetable warming plate. This application provides a liftable boss 3 and a side air outlet structure on the boss 3. With the dual support of the heating tube and the side hot air outlet, the vegetable warming plate can solve the problem of low heat transfer efficiency and slow heating effect caused by the insulation design of tableware. Specifically, the side hot air outlet can make the surface of the food reach the effect of heating, which can improve the taste of the food and enhance the user experience. In addition, due to the fan installed at the bottom, the vegetable warming plate can be cooled quickly after use.

[0061] By providing a food warming plate structure with side air outlet, the food warming plate in the present application can improve the problem that the food is cold on the top and hot on the bottom and the heating effect is slow when heating food.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
