Abstract

The invention discloses a heating device of a heater and an integrated heating pump. The heating device comprises a heat conduction cover plate, an electric heating tube and a protector, wherein two opposite side surfaces of the heat conduction cover plate are an inner side surface and an outer side surface respectively, the inner side surface is used for forming the inner wall of a containing cavity, and the heat conduction cover plate is provided with installation through holes and a thermal contact point which are separated; the electric heating tube comprises a main body heating part and connecting end parts connected with the main body heating part, the main body heating part is arranged at the inner side of the heat conduction cover plate, each connecting end part cooperates with the corresponding installation through hole, and the main body heating part is in contact with the inner side surface only at the thermal contact point; and the protector is arranged at the outer side of the heat conduction cover plate, the protector arranged by at least one, and the temperature sensing face of the at least one protector is attached to the outer side surface right in a manner of being opposite to the thermal contact point. According to the heating device, the electric heating tube is in direct contact with liquid but can be prevented from being in complete contact with the heat conduction cover plate, so that the heating efficiency is high, and the safety is high. While the potential safety hazard can be further reduced by installing the at least one protector.

Description

technical field

[0001] The invention relates to the technical field of household appliances, in particular to a heater heating device and an integrated heat pump. Background technique

[0002] During the washing process of dishwashers and washing machines, it is often necessary to heat the internal liquid to improve washing efficiency and cleanliness. Compared with split-type heaters and washing pumps, integrated heating pumps have the advantages of simple structure, small size, and high efficiency, and have gradually replaced split-type heaters and washing pumps.

[0003] At present, there are mainly two types of heaters in integrated heat pumps, including immersion type and external type. The immersion heater is used, the heater extends into the pump casing, and is installed and fixed on the plastic pump casing with a seal, the heater exchanges heat directly with the liquid, and the heating efficiency is high, but the seal, the plastic pump casing and the heater directly ...
