Domestic dish warming machine

Abstract

The invention discloses a domestic dish warming machine. The domestic dish warming machine comprises a housing (7), wherein an air circulation heating device is arranged at the side part of the housing (7), and a heating bottom plate (8) with a built-in heating module is arranged at the bottom of the housing (7); and the air circulation heating device and the heating module of the heating bottom plate are connected on a power supply in parallel. The domestic dish warming machine has the advantages of high heating efficiency and uniform and constant temperature at all points in an inner cavity.

Description

technical field [0001] The invention relates to the technical field of electric heating, and more specifically relates to a household dish warmer. Background technique [0002] As the name suggests, the household warming dish machine is a machine for drying water stains on the surface of the dish for household use. At present, most household warming machines use air circulation heating system or heat conduction heating system; air circulation heating system refers to that the fan is used as the power for the heat cycle, and the air enters the electrical enclosure from the air inlet through the impeller of the fan, and then the air is absorbed by the enclosure. The electric heating element inside is heated, and then enters the inner cavity of the household dish warmer from the air outlet, and then passes through the air inlet, and circulates in turn, so that the temperature of the inner cavity of the household dish warmer reaches the preset temperature. The defects of this wa...

Problems solved by technology

At present, most household warming machines use air circulation heating system or heat conduction heating system; air circulation heating system refers to that the fan is used as the power for the heat cycle, and the air enters the electrical enclosure from the air inlet through the impeller of the fan, and then the air is absorbed by the enclosure. The electric heating element inside is heated, and then enters the inner cavity of the household dish warmer from the air outlet, and then passes through the air inlet, and circulates in turn, so that the temperature of the inner cavity of the household dish warmer reaches the preset temperature. The defects of this warming method Yes, it takes a long time for the dish warmer to heat up to the preset temperature, that is, the thermal efficiency is low; the heat conduction heating system means that the bottom plate of the inner cavity of the dish warmer is a heat conduction plate, and the side of the dish warmer is equipped with a heating element, and the heat conduction plate conducts heat. The heat generated by the heating element achieves the effect of warming the plate through the principle of warm air floating up. The defect of this warming method is that the heat on the heat conducting plate is not uniform, that is, the heat on the heat conducting plate is relatively high near the heating element. The place where the heat conduction plate is far away from the heating element has relatively low heat, which makes the temperature of each point in the inner cavity of the dish warmer different, which affects the stability of the temperature.
