Food insulation board

Abstract

The invention provides a food insulation board. The food insulation board comprises a first board body with a first heating element and a second board body with a second heating element. The first plate body is provided with at least two foldable foot parts distributed in the circumferential direction of the first plate body, and the second plate body is provided with foot seats distributed in the circumferential direction of the second plate body. Concave cavities are formed in the upper sides of the footstands, and when the feet are in the stretching state, the feet can be inserted into the concave cavities. The bottom of at least one pin is provided with a first electrode, and the first heating element is electrically connected with the first electrode through a first wire located in the pin. A socket matched with the first electrode is arranged in at least one concave cavity, and a second electrode is arranged on the socket. When the foot part is inserted into the cavity, the first electrode is connected with the second electrode. The first plate body can be mounted on the second plate body in a stacked manner, so that the desktop space is utilized to the greatest extent. And the whole double-layer food insulation board only needs one external power line, so that the space is further saved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a food heat preservation board for food heat preservation. Background technique [0002] When the temperature is low, the dishes on the dining table tend to cool down and become cold, which is not conducive to eating. Food insulation boards arise at the historic moment, and its heating source is usually an electric heating tube or a heating wire placed under a ceramic plate or a glass plate. A power input interface, a power switch, a power indicator light and a temperature regulating device are usually arranged at the frame of the food insulation board. Thermostats are usually knobs, sliders, or buttons. Some food insulation boards are fixed power insulation boards without external temperature adjustment devices. [0003] At present, the food insulation boards for household use on the market are all single-layer, and can only be placed flat on the dining table directly. The...

Problems solved by technology

[0003]At present, the food insulation boards for household use on the market are all single-layered, and can only be placed flat on the dining table directly. The space is limited, and when there are many dishes, it is difficult to simultaneously Put down a lot of dishes, it is difficult to meet the needs of families with large consumption

[0004]Usually limited table space is difficult to lay down two single-layer food insulation boards, even if two independent single-layer insulation boards can be placed, two food insulation boards The power cord of the board will also occupy a lot of space, hindering the flexibility of personnel dining
