Heating device

Abstract

The invention relates to a heating device which comprises a furnace surface plate, a heating component, a shell and a blower, wherein the furnace surface plate is mounted on the shell; an accommodating cavity is formed between the furnace surface plate and the shell; the heating component and the blower are mounted in the accommodating cavity; the heating component is positioned below the furnace surface plate; a ventilation spacing is formed between the heating component and the side wall of the shell; the blower is arranged apart below the heating component; the air-out direction of the blower faces the heating component; a ventilation spacing is formed between the blower and the side wall of the shell; the top wall of the shell is provided with a plurality of air outlets distributed at intervals in the circumferential direction; the lower end of the shell is provided with an air inlet; and the air inlet, the ventilation spacings and the air outlets constitute a basin-shaped heat-radiating channel. According to the invention, in the working process of the blower, the heat-radiating component is always wrapped by the basin-shaped heat-radiating screen, so that the heat-radiating effect is favorable, and the efficiency is high.

Description

[0001] technical field [0002] The invention relates to a heating device. [0003] Background technique [0004] 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.

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.

[0005] 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.
