Embodiment 1

[0041] Such as Figures 2 to 3 As shown, a heating circulation pump 6 is introduced in this embodiment, which includes a pump casing 60, which is provided with a pump chamber 62 for water to flow through; the inner wall of the pump casing 60 is provided with a groove 63, the groove 63 is provided with a heating element 8, and the heating element 8 is in contact with the water flowing through the pump chamber 62 to heat the water flowing through it. The heating element 8 and the inner wall of the pump casing 60 together form a pump chamber 62, and the junction between the heating element 8 and the inner wall of the pump casing 60 forms a smooth surface, so as to prevent foreign matter such as wire scraps trapped in the water flowing through the pump chamber from being entangled by the heating element Intercept and avoid the occurrence of foreign matters such as lint dust being trapped in the pump cavity.

[0042]In this embodiment, all the heating elements 8 are located in the...

Embodiment 2

[0049] Such as figure 2 with image 3 As shown, a heating circulation pump 6 is introduced in this embodiment, which includes a pump casing 60, and a pump chamber 62 is provided inside the pump casing 60 for the water to flow through; The water inlet 66 is provided with a driving device 61 at the other end, so that the heating element 8 heats the water flowing into the pump chamber 62 from the water inlet 66 , and then the heated water flows out from the water outlet 67 through the driving device 61 . At the same time, the water inlet 66 is arranged on one end of the columnar pump casing 60, and the water outlet 67 is arranged on the side wall of the pump casing 60 near the end of the driving device 61, so that the axes of the water inlet 66 and the water outlet 67 are vertically arranged to facilitate the water inlet. The water outlet 66 and the water outlet 67 are respectively connected with pipelines.

[0050] In this embodiment, the driving device 61 includes an impelle...

Embodiment 3

[0060] Such as Figure 1-3 As shown, this embodiment introduces a washing machine equipped with the circulating heating pump 6 described in the above embodiments, which includes a housing 1; an outer tub 2 is arranged inside the housing 1, and the outer tub 2 can generate heat through a shock absorbing device. The vibration displacement is installed on the shell 1 to hold the washing water; the inner barrel 3 is provided in the outer barrel 2, and the inner barrel 3 is connected with the drive motor 10 through the rotating shaft, and is installed in the outer barrel 2 in a rotatable manner for Hold the load to be washed; the inner barrel 3 is provided with a washing hole, which is used to connect the inner barrel 3 and the outer barrel 2, so that the washing water can flow between the inner and outer barrels through the washing hole; the water inlet pipe 9, the water outlet and the The outer tub 2 is connected to each other and is used to supply water to the outer tub 2 of the...

Abstract

The invention discloses a heating circulating pump and a washing machine. The heating circulating pump comprises a pump shell which is internally provided with a pump cavity for water flow to flow, a driving device installed on the pump shell and used for providing flowing driving force for the water flow in the pump cavity, and a heating piece arranged on the pump shell, wherein at least part of the heating piece makes contact with water flowing through the pump cavity and heats the water, and the heating piece and the inner wall of the pump shell jointly form the smooth pump cavity. By means of the arrangement, the smooth pump cavity is formed in the circulating pump, so that foreign matter such as thread scraps in the water flow flowing through the heating circulating pump cannot be accumulated in the pump cavity and cannot be intercepted by the heating piece arranged in the pump cavity, and the effect that the water flow flows through smoothly is achieved; and meanwhile, the heating piece is in direct contact with the water flow flowing through the pump cavity, so that the heating piece can directly perform contact heating on the water flow flowing through the heating circulating pump, and the heating efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the field of clothes processing equipment, and in particular relates to a washing machine with a circulating spraying function, in particular to a heating cycle applied to a washing machine, which has a heating function and is used to drive washing water to circulate outside an outer tub Pump. Background technique [0002] At present, in the field of household appliances, the application of heat pumps is generally that the heating element does not directly contact with water, which can effectively prevent some foreign matter from sticking to the heating pipe, but this kind of heating efficiency is very low, about 70%, resulting in The problems of energy waste and excessive heating time are eliminated. [0003] In particular, when the above-mentioned heat pump is applied to a washing machine to heat the washing water, since the total amount of washing water in the washing machine is large, it takes longer to heat it with a non-...
