Description

A dish warmer

technical field

The utility model belongs to daily household articles, in particular to a table for heat preservation of dishes.

Background technique

In daily life, when people cook dishes, due to the limitation of the number of stoves and operating space at home, they often need to cook multiple dishes one after another. It takes a long time from the first dish to the completion of all dishes. The cooked dishes will become cold, especially in winter or when there are many dishes that need to be cooked for a group dinner. At this time, some people use the microwave oven to heat the dishes. The disadvantage is that the microwave oven space is limited, and the dishes need to be heated in sequence, which takes a long time. People will use household incubators or steamers. They all have the problem of less empty space. When there are many people dining together, there are many dishes, and it is impossible to keep warm at the same time. Therefore, people have thought of various heat preservation tables, but in summary, there are still the following defects: 1. The steam heating table is combined with the cover, and condensation water is prone to drip, which affects the appearance of the dishes, and the table will also cause water accumulation. 2. In order to lock the heat in the space formed by the desktop and the cover, the existing thermal insulation cover and the desktop are designed with a sealing structure, but it is not considered When the dishes do not need to be kept warm, the impact of the tank on daily use, such as the accumulation of dust, the scattering of vegetables and soup, etc. At the same time, the dirt in the tank is not suitable for cleaning due to the small operating space, which also causes bacterial reproduction and pollution. , is not conducive to health, and the open design of the last slot also makes the desktop unsightly; 3. The existing electric heating insulation cover products are generally powered by external drag wires, which are inconvenient and unsightly to use. They are all arranged on the upper part of the heating cover, and the heating area of the heating device is limited by the space. At the same time, due to the low density of hot air, it will float on the top, resulting in uneven heat distribution in the entire heating cover from bottom to top, and the lower part is attached to the desktop. The temperature (that is, the layer of dishes) is the lowest, and it is not easy to quickly increase the temperature, which is not conducive to the preservation of dishes.
