Heat and cold heat-preservation tray

Abstract

The invention discloses a heat and cold heat-preservation tray, which comprises a base assembly and a pot tray, wherein the base assembly comprises a main body panel, an upper frame is arranged at the upper side of the main body panel, the pot tray comprises three independent pot bodies which are buckled at the upper part of the upper frame in parallel, three heat conduction aluminium blocks matched with the bottoms of the pot bodies are arranged on the upper part of the main body panel, a semiconductor heat and cold chip is arranged at the bottom of each heat conduction aluminium block, a heat insulation foam body is inserted and fixed at the bottom of the main body panel, a heat dissipation block matched with the bottoms of the semiconductor heat and cold chips is arranged in the heat insulation foam body, the bottom of the heat insulation foam body is fixed with a base cover in an inserted connection manner, a fan matched with the bottom of the heat dissipation block is arranged at the upper part of the base cover, and the semiconductor heat and cold chips and the fan are electrically connected with a functional circuit board. The semiconductor heat and cold chips disclosed by the invention can be used for refrigerating and heating; the three pot bodies can be used respectively for heat preservation and cold insulation of various foods at the same time; and a complete heat insulation design prevents heat from being transmitted to the outer shell, thus the heat and cold heat preservation tray is safer in use.

Description

technical field [0001] The invention relates to the technical field of electric heating pans, in particular to hot and cold heat preservation plates. Background technique [0002] With the improvement of living standards, people's requirements for diet are getting higher and higher, and some foods are most delicious only at a specific temperature, so some food insulation plates have emerged as the times require. For example, the patent with the notification number CN2917466Y discloses a heat preservation tray. The heat preservation tray includes a base assembly and a dinner plate. The base assembly is provided with a heating device. container. The thermal insulation tray of the invention can directly heat the dinner tray through the heating medium, can control the heating temperature, and maintain the taste and temperature of the food in the dinner tray. [0003] But along with the diversification day by day of people's diet, not only hot meal is arranged on dining table, ...

AI Technical Summary

Problems solved by technology

[0003] But along with the diversification day by day of people's diet, not only hot meal is arranged on dining table, also can have various cold food and cold drink, therefore people hope that food can not only keep heat, but also can keep low temperature, and existing thermal insulation tray has unable to meet people's needs
