heating equipment

Abstract

Disclosed is a heating apparatus comprising an oven face plate, a heating component, a housing and a fan; wherein the oven face plate is mounted on the housing, an accommodating chamber is formed between the oven face plate and the housing, the heating component and the fan are mounted in the accommodating chamber, the heating component is located below the oven face plate, a ventilation gap is formed between the heating component and a side wall of the housing, the fan gap is located below the heating component, the outward blowing direction of the fan faces the heating component, and a ventilation gap is formed between the fan and a side wall of the housing; a top wall of the housing is provided with several air outlets distributed at intervals in the circumferential direction, a lower end of the housing is provided with an air inlet; and the air inlet, the ventilation gap and the air outlets constitute a basin-like heat-dissipation channel. In the heating apparatus, during the operation of the fan, the heating component is continually kept covered by a basin-like heat-dissipation air screen, heat-dissipation effects are good and efficiency is high.

Description

technical field [0001] The invention relates to a heating device. Background technique [0002] Existing heating appliances such as infrared heating furnaces or induction cookers generally include a housing, a heating plate located in the housing, a black crystal plate and a fan. The black crystal board is sealed and installed on the base, the fan is placed flat in the housing, and the side wall of the housing is provided with cooling holes. When the infrared heating furnace heats the container by means of infrared heating, the temperature around the heating plate also rises synchronously. Although there is a fan in the casing, because the casing only has heat dissipation holes on the side wall, convection cannot be formed, causing the hot air to gather on the base Inside, the heat dissipation effect is very poor. If this happens for a long time, it will affect the working performance of the heating appliance, and the high temperature of the base will easily burn people. ...

AI Technical Summary

Problems solved by technology

When the infrared heating furnace heats the container by means of infrared heating, the temperature around the heating plate also rises synchronously. Although there is a fan in the casing, the casing only has heat dissipation holes on the side wall, so convection cannot be formed, resulting in hot airflow gathering on the base Inside, the heat dissipation effect is very poor. If this happens for a long time, it will affect the working performance of the heating appliance, and the high temperature of the base will easily burn people.

[0003] In addition, the existing heating appliances usually automatically stop heating through temperature detection, which is easily affected by the external environment and leads to inaccurate detection, which makes the water boil for a long time and affects the water quality.
