Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, the following embodiment is an example, and does not limit the technical scope of this invention.

[0021] figure 1 It is a cross-sectional view showing a schematic configuration of washing machine 100 according to the embodiment of the present invention.

[0022] The washing machine 100 has a washing machine body 2 . A water tank 3 is housed in the inside of the washing machine main body 2 so as to be able to swing freely. In the water tank 3, the rotating drum 4 is arrange|positioned freely rotatably centering on the rotating shaft 4A. The rotating shaft 4a of the rotating drum 4 is directly connected to the motor 6 attached outside the rotating shaft 4a on the back surface of the water tank 3. As shown in FIG. The rotary drum 4 is rotationally driven by an electric motor 6 .

[0023] The rotating drum 4 is configured by providing a plurality of throug...

Abstract

A washing machine (100), comprising a rotating drum (4), a water tank (3), a water supply unit for supplying water into the water tank (3), a water level detection unit (10) for detecting the water level of washing water in the water tank (3), and a rotating speed Variable circulation pump (20). It also includes a water circulation system (16) for circulating washing water in the water tank (3) to the rotary drum (4) through a circulation pump (20), and a control unit (22) for controlling the rotation speed of the circulation pump (20). In addition, in the rinsing process, the control unit (22) drives the circulation pump (20) at the first rotational speed (S3) before the water level detection unit (10) detects the water level (S4), and then drives the circulation pump (20) at the first rotation speed (S5) after the water supply unit starts water supply (S5). After the water level detector (10) detects that the water level of the washing water has become higher than a predetermined water level (S6), the rotation speed of the circulation pump (20) is driven at a second rotation speed higher than the first rotation speed (S7).

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine for circulating spraying treatment and a rinsing method using the washing machine. Background technique [0002] A conventional front-loading washing machine includes a circulation pump and a circulation path for returning water in the water tank taken out from the water outlet to the water tank, and circulates and sprays the laundry (for example, refer to Patent Document 1). [0003] In such a washing machine, a shower rinsing operation is performed in the rinsing step, and the shower rinsing operation performs a cyclic shower process. In this shower rinsing operation, when the water level detected by the water level sensor rises to a preset water level while water is being supplied into the water tank, the circulation pump starts to be driven. [0004] Also, when the water level detected by the water level sensor falls to a detectable lower limit water level set as the lo...
