Embodiment 1

[0086] Such as Figure 1 to Figure 7 As shown, a heat pump assembly 100 includes a pump casing 10 , a pump cover assembly 20 , a water inlet assembly 30 , and a seal 40 .

[0087] The pump casing 10 has a cavity 10a inside, and the pump casing 10 is provided with an installation port 10b communicating with the cavity 10a, an impeller inlet hole 10c and a water outlet 10d.

[0088] The pump cover assembly 20 includes a heat conduction cover plate 21 , a heating pipe 22 , an anti-boiling protector 23 , and an anti-boiling protector 24 .

[0089] The heat-conducting cover plate 21 fits on the installation port 10b to seal the installation port 10b. The heating tube 22 is arranged on the heat-conducting cover plate 21 and is located in the cavity 10a. The heating tube 22 includes an arc-shaped heating portion 221 and a connecting portion 222. The heating portion 221 is arc-shaped, and the connecting portion 222 is linear. There are two connecting portions 222 connected to both en...

Embodiment 2

[0096] Such as Figure 8 and Figure 9 As shown, the structure of the heating assembly 100 in the second embodiment is substantially the same as that of the heating assembly 100 in the first embodiment, and the same parts will not be repeated here.

[0097] The difference is that in the second embodiment, the anti-boiling protector 23 and the anti-boiling protector 24 are arranged close to the connection part 222, and the temperature-sensing surfaces of the anti-boiling protector 23 and the anti-boiling protector 24 are attached to the heat conducting The side of the cover plate 21 located outside the cavity 10a.

Embodiment 3

[0099] Such as figure 1 As shown, the structure of the heating assembly 100 in the third embodiment is substantially the same as the structure of the heating assembly 100 in the first embodiment, and the same parts will not be repeated here.

[0100] The difference is that in the third embodiment, the anti-boiling protector 23 is arranged close to the connection part 222 (not shown in the figure), and the temperature-sensing surface of the anti-boiling protector 24 is attached to the heat-conducting cover plate 21, and the anti-boiling The protector 24 is arranged corresponding to the convex portion 211 or the heat conduction block (see figure 1 ).

[0101] A washing device (not shown in the figure) according to an embodiment of the present invention includes the heating assembly 100 as mentioned above.

[0102] According to the washing device of the embodiment of the present invention, the heating assembly 100 can realize the immersion heating of the liquid inside the heat ...

Abstract

The invention discloses a heating pump assembly and a washing device. The heating pump assembly includes a pump shell which is internally provided with an accommodating cavity, the pump shell being provided with a mounting port and a water outlet which are in communication with the accommodating cavity; a pump cover assembly including a heat conduction cover plate and a heating pipe, wherein the heat conduction cover plate is arranged on the mounting port in a matched mode to seal the mounting port, a part of the heat conduction cover plate is sunk towards the interior of the accommodating cavity to form a boss, the heating pipe includes a heating part and a connecting part connected with the heating part, the heating part is located in the accommodating cavity, a gap is formed between the heating part and the heat conduction cover plate, the boss is sleeved with the heating part, the heating part and the boss are spaced, the connecting part is arranged on the heat conduction cover plate in a penetrating mode, and at least one protector is arranged on the portion, located on the outer side of the accommodating cavity, of the pump cover assembly; and a water inlet assembly arranged on the boss, wherein the water inlet assembly is provided with a water inlet in communication with the accommodating cavity. The heating pump assembly is high in heating efficiency and good in heating effect, and can improve working reliability and safety of the heating pump, and the whole heating pump assembly has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a heat pump assembly and a washing device. Background technique [0002] Dishwashers and washing machines often need to heat the internal liquid during the washing process, so as to improve washing efficiency and cleanliness. Compared with split-type heaters and washing pumps, integrated heating pumps have a 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, immersion type and external type. [0004] For immersion heaters, most of the heaters extend into the pump casing and are installed and fixed on the plastic pump casing with seals. The heater exchanges heat directly with the liquid, and the heating efficiency is high. However, the seal, the plastic pump casing and the heater are in direct contact, there is a reli...
