detailed description

The embodiments of the present invention are described in detail below, and the examples of the embodiments are illustrated in the drawings, wherein the same or similar reference numerals are used to refer to the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A washing machine in accordance with an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a washing machine according to an embodiment of the present invention includes a detergent storage box 10, a dispensing pump 20, a transfer box 30, a switching unit, a first washing tub 501 and a second washing tub 502.

Specifically, the dispensing pump 20 has an inlet 201 and an outlet 202. The inlet 201 of the dispensing pump 20 is in communication with the detergent storage box 10.

The transfer box 30 has a liquid inlet 301, a first liquid outlet 302, and a second liquid outlet 303. The liquid inlet 301 of the transfer box 30 is connected to the outlet 202 of the delivery pump 20.

The switching unit is mounted on the intermediate transfer box 30 for selectively connecting the liquid inlet 301 with the first liquid outlet 302 or the second liquid outlet 303, wherein the first liquid outlet 302 is adapted to be A washing tub 501 is connected, and the second liquid outlet 303 is adapted to be connected to the second washing tub 502.

In some embodiments of the invention, the transfer box 30 and the switching unit are a unitary piece. In an embodiment of the invention, the washing machine comprises an electromagnetic steering valve comprising a relay box 30 and a switching unit, that is to say, the relay box 30 and the switching unit herein are substantially a single piece, which is electromagnetic Steering valve. Of course, in other realities In the embodiment, the relay and 30 and switching unit can be two separate components.

More specifically, as shown in FIG. 2, according to an example of the present invention, the switching unit is a solenoid valve 40 that selectively closes the first liquid outlet 302 or the second liquid outlet 303.

Advantageously, the solenoid valve 40 includes an electromagnet 401, a core 402 and a spring 403.

A passage (not shown) having an opening downward (i.e., as shown in the lower portion of Fig. 2) is defined in the electromagnet 40.

The iron core 402 is disposed in the passage in a vertically movable manner.

The upper end of the spring 403 abuts against the top wall of the passage and the lower end of the spring 403 abuts against the upper end of the core 402 to push the core 402 downward.

That is, when the solenoid valve 40 is in the de-energized state, the spring 403 pushes the core 402 downward to close the second liquid outlet 303 to allow the liquid inlet 301 to communicate with the first liquid outlet 302. At this time, if the delivery pump 20 is started, the detergent can be dispensed into the first washing tub 501. When the electromagnetic valve 40 is in the power-on state, the electromagnet 40 generates an upward suction force to attract the iron core 402, and the iron core 402 moves upward against the elastic force of the spring 403 to close the first liquid outlet 302, so that the liquid inlet 301 and the liquid inlet 301 are The second liquid outlet 303 is in communication. At this time, if the delivery pump 20 is started, the detergent can be dispensed into the second washing tub 502.

Further, as shown in FIG. 2, the solenoid valve 40 further includes a gasket 404. A gasket 404 is provided at the lower end of the core 402. The gasket 404 can be a rubber gasket. Thus, the sealing effect is good.

According to the washing machine of the embodiment of the invention, the second washing tub 502 is an ultrasonic washing tub.

As shown in FIG. 1, the washing machine further includes a water inlet valve 60, according to an example of the present invention. The water inlet valve 60 is provided between the detergent storage box 10 and the dispensing pump 20. Thus, after the detergent is dispensed, the pipeline can be flushed to avoid mixing between the different detergents, and waste is also prevented from remaining in the pipeline.
