Description

Heating and heat preservation lunch structure

This creation relates to a structure for heating and holding a lunch, especially a structure for heating and keeping the food, the dish steamed, or the steamed cooked food.

According to the general situation, when I use it, I put rice, dishes, etc. directly into the lunch. If I want to keep the heat in the winter, I need to heat the lunch with a steamer or other steaming device, which is not only troublesome but also due to work. There is no time to deal with it when you are busy. Therefore, some people use a kind of heat-insulated lunch to accommodate food. However, the heat preservation effect of the conventional heat preservation lunch will decrease with time, and it is impossible to maintain the temperature by the outside, and it is impossible to reheat the food, so that the practical value of the heat preservation lunch is lowered. . In view of this, the applicant has been practicing the business for many years. After continuous research and experimentation, Yan Mengsheng has improved a heating and heat preservation convenience structure to enable the contents of the convenience to achieve heat retention for a long time.

The main purpose of this creation is to provide a heating and heat preservation lunch structure that allows the heat preservation convenience to maintain the desired thermal temperature by heating to constitute a long-term heat retention effect of the food inside the lunch.

The foregoing heat insulation and heat preservation structure comprises a body, a base, and a plurality of accommodating boxes stacked in the body. Wherein, the wall surface of the body is hollow, to constitute a heat preservation function, and the bottom edge is provided with a water tank for accommodating water, and an electric heating element is arranged on the bottom surface thereof, and the base is provided with a control circuit, which is controlled by The circuit is connected to the electric heating element and is provided in the control circuit The setting keys and sockets exposed on the base. When in use, the food and dishes are placed in the receiving box, connected to the mobile power source or the transformer through the socket, and the control circuit is started by the setting button, and the heating element is heated to form the water of the water tank, thereby forming the pair of accommodations. The hot food of the food and dishes of the box, or the steamed food, makes it easier to use the insulation.

The foregoing heating cup structure, wherein the socket is arranged on the base, is a USB socket.

Please also refer to Figure 1 and Figure 2, together with Figure 3, which is a perspective view, an exploded view and a cross-sectional view of the creation. As shown in the figure, the present invention comprises a body 1, a base 2, and a plurality of receiving boxes 3, 4, 5 and an upper cover 6 stacked in the body 1. Wherein, the wall surface of the body 1 is hollow, to constitute a heat preservation effect, the inner edge of the wall is provided with a plurality of vertical grooves 10, and the bottom edge is provided with a water tank 11 for accommodating water, the water tank The upper edge of the body 11 is provided with a flange portion 111 extending inwardly of an appropriate length. The bottom surface of the body 1 is provided with an electric heating element 12 (which is a ceramic electric heating sheet or a heating wire), so that the electric heating element 12 is closely attached to the bearing body 1. Bottom outer edge. The base 2 is provided with a control circuit 21 connected to the electric heating element 12 by the control circuit 21, and the setting circuit 22 and the power indicator light 221 exposed on the base 2 are provided in the control circuit 21. (Light-emitting diode) and socket 23 (in the present embodiment, the socket 23 is a USB socket), and the socket 23 is connected by a wire 24 for plugging in the mobile power source 25 or the transformer 26 (for converting AC power into DC). The receiving box 3 can be provided with a plurality of partitions to form a plurality of storage areas 31.

The combination of the foregoing members constitutes a heating and heat insulating lunch structure. When it is used, the food such as rice is placed in the accommodating box 5, and the different dishes are placed in the storage areas 31 or the accommodating case 4 of the accommodating case 3, and the appropriate amount of water is poured into the water tank 11 of the body 1. After that, the accommodating boxes 3, 4, and 5 are placed in the main body 1 and the upper cover 6 is closed, and the socket 23 is connected to the mobile power source 25 or the transformer 26, and the control circuit 21 is activated by the setting button 22, and is displayed. The lamp 221 is shown in an activated state, and the 俾 driving electric heating element 12 is configured to heat the water of the water tank 11 to generate steam, so that the vapor rises along the groove 10 and fills the inside of the bearing body 1, thereby constituting the accommodating case 3, 4, 5 The food and the dish are steamed hot, and the control circuit 21 can automatically stop the electric heating element 12 after heating to a certain temperature, so that the use of the heat preservation convenience is more convenient. Wherein, since the water tank 11 of the bearing body 1 is provided with an inwardly extending weir portion 111 to constitute a proper shielding function to prevent the entire heat insulating toilet from being shaken or tilted, the water in the water tank 11 overflows outward, so that the water in the water tank 11 overflows. The use of insulated lunch is more secure.

Please refer to Figure 4 for the usage status diagram of this creation. Please refer to FIG. 1 and FIG. 2, as shown in the figure, when the present invention is used, it is connected to the mobile power source 25 via the socket 23 or plugged into the transformer 26, and the setting key 22 is used to set the temperature to be heated. And displayed by the display lamp 221, the introduced power source drives the electric heating element 12 via the control circuit 21, and after the electric heating element 12 generates thermal energy, the water of the water tank 11 of the support body 1 is heated, and when the water of the water tank 11 is heated to a boiling state. At this time, a large amount of steam will be generated to cause the vapor to rise along the groove 10, The heating of the contained food and dishes is constituted by steam, and the control circuit 21 can automatically stop the electric heating element 12 after heating to boiling for a certain period of time. When the temperature of the food and the dish is lowered, the electric heating element 12 can be activated again to form a reheating, which makes the use of the heat preservation convenience more convenient.
