Description

Technical Field

[0001] This application relates to the field of food warming boards, and more particularly to a smart food warming device. Background Technology

[0002] A food warmer is a small kitchen appliance that uses electric heating elements to heat or maintain the temperature of food placed on it. For example, when the indoor temperature is relatively low, or when a user needs to prepare several dishes but cannot finish them all at the same time, the food will quickly cool down to room temperature after being served, affecting its taste. Therefore, a food warmer can keep the food warm, allowing people to enjoy delicious food during the meal.

[0003] Among them, Chinese utility model patent, patent number: CN221180227U, discloses an intelligent food warming device, including a food warming board body. The bottom surface of the food warming board body is provided with heat-insulating support blocks, and a heat dissipation channel communicating with the outside is formed between the heat-insulating support blocks and the bottom surface of the food warming board body. The food warming board body is provided with a heat dissipation device to increase the air flow rate in the heat dissipation channel and reduce the temperature of the bottom of the food warming board body. By providing multiple mutually spaced and downwardly protruding heat-insulating support blocks on the bottom surface of the food warming board body, the food warming board body is suspended on the table, which can prevent the food warming board body from burning the table. At the same time, the heat dissipation device on the food warming board body can increase the air flow rate in the heat dissipation channel and reduce the temperature of the bottom of the food warming board body. In this way, even if the temperature of the upper surface of the food warming board body is increased, the food warming board body will not burn the table. It can heat the food warming board, has high practical value, and is conducive to promotion and application.

[0004] However, the problem with this type of food warmer is that it has a certain thickness and a limited effective heating area. At the same time, the area of ​​the dining table is also limited. As a result, the food warmer can only hold a certain number of plates. The remaining plates containing food can only be placed on the table outside the food warmer, resulting in low effective utilization of the area. In addition, when the food warmer is working, in order to keep the plates on the food warmer warm or heat them at the same time, the heating element of the food warmer is always in working condition, resulting in relatively high power. There is room for improvement. Utility Model Content

[0005] To facilitate the keeping or heating of dishes, this application provides an intelligent food warming device.

[0006] The intelligent food warming device provided in this application adopts the following technical solution:

[0007] A smart food warming device includes a main controller and several sub-food warming plates. The main controller is equipped with a power interface and several working interfaces, the same number as the number of food warming plates. The power interface is used to connect an external power source to power the main controller. A connecting wire is provided between the working interface and the sub-food warming plate. The sub-food warming plate and the working interface are electrically connected to the main controller through the connecting wire, and the connecting wire is detachably connected to the working interface. The main controller is used to adjust the working status of the sub-food warming plates.

[0008] By adopting the above technical solution, the main controller is equipped with a power interface, which supplies power to the main controller. The main controller also has several working interfaces, and the number of sub-warming plates matches the number of working interfaces. The main controller and the sub-warming plates are connected via connecting cables. Users can freely control the number of sub-warming plates connected to the main controller according to their needs. Sub-warming plates only work when connected to the main controller via connecting cables; those not connected are inactive. This positively contributes to reducing the overall energy consumption of the food warming device. Furthermore, the placement of the sub-warming plates along the table can be adjusted freely, improving the space utilization of the dining table and not affecting the heating or temperature control of the plates placed on them. This positively contributes to improving the heating or heat preservation of the dishes.

[0009] Preferably, the sub-warming plate includes a base, and the base has a receiving groove for receiving the connecting wire.

[0010] By adopting the above technical solution, when the sub-warming cutting board does not need to be connected to the main controller via a connecting cable, the connecting cable can be stored in the receiving slot, reducing the space occupied by the sub-warming cutting board, so as to facilitate the stacking and storage of several sub-warming cutting boards.

[0011] Preferably, the sub-warming cutting board further includes a placement section for placing plates.

[0012] By adopting the above technical solution, the placement part helps to improve the stability of the plate when it is placed on the warming plate, and at the same time, it helps to increase the contact area between the plate and the warming plate, and helps to better conduct the heat emitted by the warming plate to the plate.

[0013] Preferably, when the connecting line is located within the receiving groove, the sub-warming plate is used to place a plate or to act as a mat.

[0014] By adopting the above technical solution, if the plate currently holding the food does not need to be kept at a constant temperature or heated (e.g., for cold dishes), the sub-warming cutting board can be used as a placemat, which is highly practical.

[0015] Preferably, the sub-warming plate is provided with a plug interface, and the end of the connecting wire away from the working interface is plugged into the plug interface. The plug interface is provided with a plug for sealing the plug interface.

[0016] By adopting the above technical solution, the sub-warming plate is equipped with a plug interface. When the sub-warming plate is not in use, the connecting wire can be removed along the plug interface, and the plug interface can be sealed by plugging. The sub-warming plate can then be rinsed directly without any foreign objects entering the plug interface, making it easy to clean the sub-warming plate.

[0017] Preferably, the base is provided with a support structure.

[0018] By adopting the above technical solution, the base is equipped with a support structure, which helps to improve the heat dissipation capacity of the base and reduces the probability of damage to the dining table or the surface to be placed due to excessively high base temperature.

[0019] Preferably, the main controller has a storage area for storing connecting cables.

[0020] By adopting the above technical solution, the main controller has a storage area, which makes it easy to store the connecting cable directly inside the main controller, effectively reducing the probability of the connecting cable being lost due to inconvenience in storing the connecting cable.

[0021] Preferably, it also includes a mother warming plate, and the main controller is disposed on the mother warming plate.

[0022] By adopting the above technical solution, the main controller is integrated into the warming plate, so that plates can also be placed on the warming plate without affecting the normal operation of the main controller, thus effectively improving space utilization.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Users can freely control the number of sub-warming plates connected to the main controller according to their usage needs. The sub-warming plates can only work when they are connected to the main controller via the connecting cable. Sub-warming plates not connected to the main controller are in a non-working state, which plays a positive role in reducing the overall energy consumption of the food warming device. In addition, the placement of the sub-warming plates along the table can be adjusted at will, which is conducive to improving the space utilization of the sub-table.

[0025] 2. When the sub-warming plate does not need to be connected to the main controller via a connecting cable, it can be connected through the receiving slot.

[0026] The wiring is stored to reduce the space occupied by the sub-cutting boards, so that several sub-cutting boards can be stacked and stored together.

[0027] 3. Integrate the main controller into the pre-warmed cutting board, so that plates can also be placed on the pre-warmed cutting board.

[0028] Furthermore, it will not affect the normal operation of the main controller, effectively improving space utilization. Attached Figure Description

[0034] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0035] This application discloses an intelligent food warming device. (Refer to...) Figures 1-3 A smart food warming device includes a main controller 1 and several sub-food warming plates 2. The main controller 1 is equipped with a power interface 11 and several working interfaces 12, the same number as the sub-food warming plates 2. The power interface 11 is used to connect an external power source to power the main controller 1. A connecting cable 3 is provided between the working interface 12 and the sub-food warming plate 2. The sub-food warming plate 2 and the working interface 12 are electrically connected to the main controller 1 through the connecting cable 3, and the connecting cable 3 is detachably connected to the working interface 12. The main controller 1 is used to adjust the working state of the sub-food warming plates 2.

[0036] First, the "main controller 1" mentioned in this embodiment can be a microcontroller unit (MCU), which integrates a central processing unit (CPU), memory and additional peripheral circuits, and is integrated on a single chip. It is an existing controller that can be used to adjust the working power, time, power on or off, lock and other working modes of the food warming device. It is intelligent and convenient. Its specific composition and working principle will not be described in detail here. At the same time, the main controller 1 can be powered by connecting the host controller to the household power grid (mains power) through the power interface 11 with a wire. The operation is simple.

[0037] Furthermore, the sub-warming cutting board 2 includes a base 21, a placement part 22, and a heating element (not shown in the figure). The placement part 22 is used to place the plate. The placement part 22 covers the base 21 and covers the heating element between the base 21 and the placement part 22, thereby protecting the heating element and enabling the heating element to work normally when powered on.

[0038] Correspondingly, the heating element can be a heating wire or heating plate, etc., which are used to realize electrothermal conversion. Since the function of the food warming device in this application is to keep the food in the plate constant or heat it, its working limit temperature rise value is 130°C (International System of Units, degrees Celsius). It plays the same role in this embodiment, and the specific type of heating element is not limited or described here.

[0039] It should also be noted that the shapes of the main controller 1 and the sub-warming plate 2 can be flexibly changed according to usage requirements (such as round, rectangular, rhomboid or other irregular shapes, etc.), and their specific shapes are not limited here.

[0040] Meanwhile, the base 21 has a receiving groove 211, which is used to abut against the dining table (or other placement surface) so that the sub-warming plate 2 can be stably placed on the dining table. The receiving groove 211 is used to store the connecting wire 3. The receiving groove 211 is formed by the base 21 being recessed along the thickness direction. When the connecting wire 3 is located in the receiving groove 211, the connecting wire 3 is snapped in place by the receiving groove 211. Thus, when the sub-warming plate 2 does not need to be connected to the main controller 1 through the connecting wire 3, the connecting wire 3 can be stored through the receiving groove 211, reducing the space occupied by the sub-warming plate 2, so that several sub-warming plates 2 can be stacked and stored together.

[0041] Furthermore, a protective ring (not shown in the figure) is provided at the edge of the placement part 22. The protective ring is used to contain liquid. When the plate is placed on the placement part 22, the liquid that spills along the plate will be stored on the placement part 22 by the blocking effect of the protective ring, and will not spill onto the table, thus improving the overall cleanliness.

[0042] It should be mentioned here that the "placement part 22" can be made of silicone. The silicone material has the characteristics of temperature resistance and stable physical and chemical properties, so that the plate will not make any noise when placed on the placement part 22, and the placement part 22 is easy to clean.

[0043] Meanwhile, when the connecting line 3 is located in the receiving groove 211, the sub-warming cutting board 2 is used to place plates, or to act as a mat. If the plate currently holding the food does not need to be kept at a constant temperature or heated (e.g., for cold dishes), the sub-warming cutting board 2 can be used as a placemat, which is highly practical.

[0044] In another embodiment, the sub-warming cutting board 2 is provided with an interface 23. The end of the connecting wire 3 away from the working interface 12 is inserted into the interface 23. A plug (not shown in the figure) is provided on the interface 23 to seal the interface 23. Since the sub-warming cutting board 2 is provided with an interface 23, when the sub-warming cutting board 2 is not in use, the connecting wire 3 can be removed along the interface 23 and the interface 23 can be sealed by the plug, so that the sub-warming cutting board 2 can be directly rinsed without foreign objects entering the interface 23, which facilitates the cleaning of the sub-warming cutting board 2.

[0045] In addition, a support structure 212 is provided on the base 21. The support structure 212 is composed of several protruding ridges formed along the base 21. Because the base 21 is provided with a support structure 212, it is beneficial to improve the heat dissipation capacity of the base 21 and reduce the probability of damage to the dining table or the table surface caused by the base being too hot.

[0046] Meanwhile, after the insertion port 23 is sealed by plugging, the placement part 22 of the sub-warming cutting board 2 can also be used as a bone plate. After use, the sub-warming cutting board 2 can be cleaned.

[0047] Meanwhile, a storage area (not shown in the figure) is provided on the main controller 1. The storage area is used to store the connecting cable 3. The storage area can be formed by recessing from the side wall of the main controller 1 toward the geometric center of the main controller 1, which improves the convenience of placing the connecting cable 3 in the storage area.

[0048] In yet another embodiment, reference is made to Figure 4 It also includes a mother warming plate 4, on which the main controller 1 is mounted. The mother warming plate 4 and the daughter warming plate 2 have the same components, which will not be described in detail here. By integrating the main controller 1 onto the mother warming plate 4, plates (such as soup bowls or soup pots) can also be placed on the mother warming plate 4, while the daughter warming plate 2 is used to place plates, forming a shape where the plates are located around the soup pot, which is more aesthetically pleasing and does not affect the normal operation of the main controller 1, effectively improving space utilization.

[0049] The implementation principle of the intelligent food warming device in this application embodiment is as follows: The main controller 1 is equipped with a power interface 11, which supplies power to the main controller 1. Simultaneously, the main controller 1 has several working interfaces 12, and the number of sub-food warming plates 2 is matched with the number of working interfaces 12. The main controller 1 and the sub-food warming plates 2 are connected via connecting cables 3. Users can freely control the number of sub-food warming plates 2 connected to the main controller 1 according to their needs. Only when a sub-food warming plate 2 is connected to the main controller 1 via connecting cables 3 can the sub-food warming plate 2 work; sub-food warming plates 2 not connected to the main controller 1 are in a non-working state. This positively guides the reduction of the overall energy consumption of the food warming device. Furthermore, the placement of the sub-food warming plates 2 along the table can be adjusted freely, which is beneficial for improving the space utilization of the table and will not affect the heating or temperature control of the plates placed on the sub-food warming plates 2, thus positively guiding the improvement of the heating or heat preservation effect of the dishes.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
