Description

Technical Field

[0001] The utility model relates to the technical field of tableware, and more specifically, to a rechargeable vegetable warming plate. Background Art

[0002] Currently, heating pads on the market are usually used for family gatherings, so most companies will choose to conduct research and development in areas such as how to increase the heated area, how to achieve local heating, and how to control the heating position. These research and development directions are mainly for indoor use. Given the current popular trends, camping has become the most popular outdoor activity for young people in spring and autumn. Food cools down faster outdoors than indoors. Because few people have outdoor power supplies when camping, plug-in heating pads can hardly meet the needs of outdoor use. Not only for outdoor use, for the catering industry, diners eat in restaurants, especially large gatherings of people, such as class reunions and annual meetings, which usually last about 1-2 hours. Long periods of drinking and chatting will also cause the dishes to cool down. If plug-in heating pads are chosen in the restaurant, the wiring needs to be modified, which is time-consuming and labor-intensive. Combining the above two points, it can be seen that at present, whether it is used outdoors or indoors, there is an urgent need for a food warming board that can heat without being plugged in and can take up less storage space when not in use. Therefore, how to make the food warming board usable without being plugged in, reduce the storage space of the food warming board, and avoid damage to the heating source when stored are technical problems to be solved by the present invention. The present invention will also solve at least one of the above technical problems. Utility Model Content

[0013] Compared with the prior art, the present invention has at least the following beneficial effects:

[0014] The food warming plate can be converted from a plug-in type to a rechargeable type, making it suitable for keeping food warm during outdoor camping and long-term dining gatherings. The structure of the new device is simple, as the side wall of the panel is provided with a housing, and the power supply and controller are both located inside or on the housing. This allows the device to be manufactured separately during production: the heating portion (panel and heating source), the power supply portion (housing portion, power supply, charging port), and the control portion (controller). In addition, if the food warming plate malfunctions, only the corresponding parts need to be replaced, rather than the entire device.

[0015] The rechargeable vegetable warming plate described in the present invention and other advantages, objectives and features of the present invention will be partially reflected in the following description and will also be understood by those skilled in the art through research and practice of the present invention.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0022] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0023] like Figure 1-Figure 3 As shown, the present invention provides a rechargeable food warming plate, comprising: a panel 1 provided with a heating source 5, and a receiving portion 2 provided on the side wall of the panel 1. The heating source 5 can be a resistance wire heater, a graphene heater, or any commercially available product or existing technology that can heat and keep the food on the panel 1 warm. The heating source 5 can be built into the panel 1 or provided at the bottom of the panel 1, as long as the heating source 5 can be installed on the panel 1 and can transfer heat to the food on the panel 1. A power source is provided in the receiving portion 2, which is usually a rechargeable battery. A controller 3 is provided on the top surface of the receiving portion 2 or the top surface of the panel 1. The controller 3 can be a commercially available product or any existing technology that can switch and control the heating source 5. The power source and the heating source 5 are both electrically connected to the controller 3. A charging port 4 is provided on the side wall of the receiving portion 2, which is electrically connected to the power source. This allows the food warming plate to be converted from the plug-in type of the prior art to a rechargeable type, making it suitable for keeping food warm during outdoor camping, as well as during long-term dining gatherings. The structure of the novel device is simple, as the side wall of the panel 1 is provided with a housing portion 2, and the power supply and controller 3 are both provided inside or on the housing portion 2. This allows the device to be manufactured separately during production, including the heating portion (panel 1 and heating source 5), the power supply portion (housing portion 2, power supply, charging port), and the control portion (controller 3). In addition, when the food warming plate fails, it does not need to be replaced as a whole, only the corresponding parts need to be replaced.

[0024] To make this new model more suitable for outdoor use, compared to the thick and bulky heating pads in the existing technology, this new model has been further optimized. In order to reduce the overall weight of the food warmer and make it more portable, the thickness of the panel 1 can be reduced while ensuring the heating area remains unchanged, thereby reducing some of the weight. Although the thickness of the panel 1 is reduced, the volume of the container 2 cannot be further reduced because the power supply is built into the container 2. For this reason, the thickness of the panel 1 is smaller than that of the container 2. In this case, the panel 1 and the container 2 may not be on the same surface, which leads to two different embodiments of the new model.

[0025] In the first embodiment, the bottom surface of the receiving portion 2 and the bottom surface of the panel 1 are located on the same plane;

[0026] When the food warming plate is unfolded and in use, the bottom surfaces of the receiving portion 2 and the panel 1 are both attached to the tabletop. Because the thickness of the panel 1 is smaller than that of the receiving portion 2, the receiving portion 2 protrudes from the top surface of the panel 1. This is the simplest embodiment, and in addition to being simple in production process, it does not require any additional structures, resulting in the lowest production cost and the lightest weight.

[0027] In the first embodiment, if both the heating source 5 and the panel 1 are made of flexible materials, the panel 1 can be wrapped around the housing 2 with the housing 2 as the rotation axis when stored. This allows the device to be rolled up when not in use, effectively saving storage space. This makes the device suitable not only for outdoor activities such as camping, but also for use in areas without a flat surface such as a table, as long as the panel 1 can be spread out. This embodiment is particularly suitable for mountaineering, hiking, and fishing enthusiasts, and can be used on a variety of terrains, including streams, grasslands, rocky areas, and sandy terrain.

[0028] Although the first embodiment has the lowest production cost and the most diverse usage scenarios, when it is rolled up, the circuit of the heating source 5 set on the panel 1 will be bent at a large angle. In addition, since the first embodiment does not have clear requirements for the winding direction, for example, it can be rolled clockwise or counterclockwise, if the user always rolls it in one direction, the damage to the circuit of the heating source 5 is not very large. Once the user repeatedly rolls it in two directions, the circuit of the heating source 5 will easily become fatigued and damaged after repeated bending. In addition, the damage to the circuit of the heating source 5 at the connection between the panel 1 and the accommodating portion 2 is the most serious because there may be a 90° bend. In view of this situation, in order to extend the service life of the heating part, we provide a second embodiment.

[0029] In the second embodiment, the top surface of the receiving portion 2 and the top surface of the panel 1 are located on the same plane. In this case, when the warming plate is laid out on the table, the bottom of the receiving portion 2 will be in contact with the table, while the panel 1 will be spaced apart from the table. To this end, a plurality of support columns 6 are provided at the bottom of the panel 1. The support columns 6 extend from the bottom surface of the panel 1 away from the panel 1 to support the panel 1. In order to reduce the weight of the support columns 6, the cross-section of the support columns 6 is usually cross-shaped, such as Figure 2 Compared with the first embodiment, the second embodiment has some limitations on application scenarios. Because the support column 6 is added, it is slightly heavier than the first embodiment. Moreover, the presence of the support column 6 makes it impossible to be applied to all terrains like the first embodiment. It is necessary to ensure that the support column 6 and the bottom surface of the receiving portion 2 are on the same plane.

[0030] In the second embodiment, if the heating source 5 and the panel 1 are both made of flexible materials. The end of the support column 6 away from the panel 1 is arc-shaped. When the panel 1 is bent and wrapped around the outer wall of the receiving portion 2, the two side walls, bottom and top of the receiving portion 2 wrapped by the panel 1 are all in contact with the end of the support column 6 away from the panel 1. Different from the low-life heating source 5 of the first embodiment, in the second embodiment, a support column 6 with an arc-shaped end is used. Because of the presence of the support column 6, the user will be guided to wind the panel 1 with the plane facing outward and the support column 6 facing inward when winding, thereby avoiding repeated bending of the circuit of the heating source 5 during winding and increasing the service life of the heating source 5. At the same time, when winding, the support column 6 will abut against the two side walls and bottom surface of the receiving portion 2. After it is rolled around, the support column 6 will abut against the top surface of the receiving portion 2 (if the length of the panel 1 can wrap the receiving portion 2 for more than one week, the outer panel 1 will abut against the surface of the inner panel 1 through the support column 6). Figure 3 In addition to guiding the winding direction, the support column 6 also prevents the heating source 5 from bending at an excessively large angle during winding. This is because after the support column 6 abuts against the side walls, bottom surface, and top surface of the receiving portion 2, it increases the winding radius of the panel 1, thereby preventing the heating source 5 from being shortened in service life due to an excessively large bending angle.

[0031] A discharge port is also provided on the side wall of the receiving portion 2, and the discharge port is electrically connected to the power supply through the controller 3, so that the present invention has the function of heating and keeping warm the food, and can temporarily serve as a power bank to power other low-power electrical devices. After the low-power electrical devices are connected to the discharge port through the power line, they can be controlled by the controller 3.
