Food heater

Abstract

The invention discloses a food heater. The food heater comprises a box body with a heating assembly, and a box door is arranged on the outer surface of the box body. The food heater further comprises an inner container which is sealed by the box door and used for heating food, a steam recovery device and a control circuit, wherein a door lock is arranged between the box door and the inner container, and transnormal steam pressure in the heating box body can be borne by the door lock; the heating assembly comprises a heating part and a water storage tank, water quantitatively output of the water storage tank is heated into steam through the heating part, and food is heated by the steam in the inner container; the steam recovery device is composed of a condenser, a steam pipe and a return pipe, the heating box body and the condenser are connected through the steam pipe, and the condenser and the water storage tank are connected through the return pipe; the control circuit controls the food heater to complete the whole work process; due to a sealing structure between the box door and the inner container, steam pressure in the heating box body is increased, heating efficiency of the heather is improved, a large part of steam is returned to the water storage tank after being condensed through the transnormal pressure in the heating box body, heated water can be utilized in a circulating mode, and environmental pollution caused by steam leakage can be avoided or reduced.

Description

technical field [0001] The invention relates to a food heater, in particular to a food heater which uses steam to heat food. Background technique [0002] At present, the food heater using steam heating in the prior art includes a food heating box, and a heater and a control device for generating steam are arranged in the heating box. The water is heated into steam to heat the food. [0003] The disadvantage of this structure is: the steam pressure in the heating box is normal pressure, the heating efficiency is relatively low, and the steam generated by heating is finally discharged into the working environment, which not only affects the humidity of the surrounding environment, but also causes damage to the kitchen utensils in the environment. damage, and at the same time cannot fully utilize the heating water. Contents of the invention [0004] The purpose of the present invention is to overcome the defects in the above-mentioned prior art, improve the high pressure r...
