Embodiment 1

[0040] Such as figure 2As shown, a heating cycle pump is introduced in this embodiment, which includes a pump casing 60, and a pump cavity 62 for water flow is arranged inside the pump casing 60; a driving device 61 is installed on the pump casing 60 for driving the pump The water flow in the chamber 62 provides the flow driving force; the driving device 61 includes an impeller 68 disposed in the pump chamber, and the impeller 68 is made of metal, so that the impeller 68 directly constitutes the metal part 63 . The components of the impeller 68 contain materials such as iron, so as to be excited by eddy currents in the high-frequency alternating magnetic field generated by the electromagnetic heating module 64 to generate self-heating.

[0041] In this embodiment, the impeller 68 is entirely made of metal material, or partially made of metal material; preferably, at least a surface portion of the impeller 68 is made of metal material. Thereby, the impeller 68 of the driving ...

Embodiment 2

[0044] Such as image 3 As shown, a heating cycle pump is introduced in this embodiment, which includes a pump casing 60, and a pump cavity 62 for water flow is arranged inside the pump casing 60; a driving device 61 is installed on the pump casing 60 for driving the pump The water flow in the chamber 62 provides the flow driving force; the driving device 61 includes an impeller 68 arranged in the pump chamber 62 , and a metal part 63 is installed on the impeller 68 . The components of the metal piece 63 include materials such as iron, so as to be excited by eddy currents in the high-frequency alternating magnetic field generated by the electromagnetic heating module 64 to generate self-heating.

[0045] In this embodiment, the impeller 68 includes a plurality of blades 681 extending radially from the central rotating shaft, and each blade 681 is symmetrically arranged relative to the central rotating shaft. The impeller 68 is made of non-metallic material, and each blade 681...

Embodiment 3

[0054] Such as Figure 4 As shown, a heating cycle pump is introduced in this embodiment, which includes a pump casing 60, and a pump cavity 62 for water flow is arranged inside the pump casing 60; a driving device 61 is installed on the pump casing 60 for driving the pump The water flow in the cavity 62 provides the flow driving force; the inner wall of the pump cavity 62 is equipped with a metal piece 63 . The components of the metal piece 63 include materials such as iron, so as to be excited by eddy currents in the high-frequency alternating magnetic field generated by the electromagnetic heating module 64 to generate self-heating.

[0055] In this embodiment, the metal piece 63 is fixedly installed on the inner wall of the pump chamber 62, and the metal piece 63 is in the high-frequency magnetic field generated by the electromagnetic heating module 64. The contacted flowing water conducts heat exchange and heats the water to achieve the effect of heating the water flowin...

Abstract

The invention discloses a heating circulating pump and a washing machine. The heating circulating pump comprises a pump shell 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 an electromagnetic heating module arranged on the pump shell, wherein a metal piece making contact with flowing water is arranged in the pump cavity, and the metal piece heats the water flowing through the pump cavity under the action of a high-frequency magnetic field generated by the electromagnetic heating module. By means of the arrangement, an electromagnetic heating device is integrated on the pump, so that the effect of conducting remote power supply transmission and heating on the water flow flowing through the circulating pump through the electromagnetic effect is achieved; and meanwhile, the metal piece is arranged in the pump cavity, and the metal piece is laid on the inner wall of the pump shell or integrated on other components in the pump cavity, so that the metal piece for heating the water flow is arranged in a hidden mode, and the problem that foreign matter such as thread scraps in the water flow flowing through the circulating pump is intercepted and accumulated at the position of the pump cavity is solved.

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-...
