As shown in fig. 1, there is provided a washing machine which is structurally composed mainly of a water tank, a drainer, a washing pump 70 and a shower 60.

Wherein the tub is used to provide a washing space, into which water for washing and fruits, vegetables or dishes to be washed can be loaded. According to different objects to be washed, the washing machine can be called as a fruit and vegetable cleaning agent and a dish washing machine. The washing machine is also called a water tank type washing machine or a dish washing machine because the washing machine is provided with a water tank.

As is conventional, the washing pump 70 supplies water to the sprayer 60, and the sprayer 60 sprays the water toward the dishes or the fruits and vegetables to wash the dirt on the dishes or the fruits and vegetables in a rinsing manner.

The structure of the washing pump 70 mainly includes a pump cover 40, an impeller and a motor, and the operation principle is well known in the industry and will not be described in detail.

The structure of the shower 60 mainly comprises a shower arm, which can be a fixed orientation spray or a rotary spray, the power of the rotary spray usually depends on the reaction force of the water jet, and can be found in patent documents or books related to the shower arm.

After the cleaning machine finishes cleaning, sewage generated by cleaning is discharged, usually, a water outlet is formed in the bottom of the water tank, a drainer is mounted at the water outlet and usually has a structure for separating slag and discharging water, and separation of sewage and waste slag and starting and interruption of water discharging can be controlled.

For reasons of simplified structure and reduced cost, the present embodiment provides a washing machine with various improvements in structure, the drainer and the washing pump 70 are shared by parts, and auxiliary devices are added to improve the washing capacity of the washing machine.

As shown in fig. 1, in summary, at the water outlet of the water tank, a water collecting tray 10, a slag separating basket 20, a filter cartridge 30, a screw cap 50, a pump cover 40, an impeller and a motor of a washing pump 70, a valve core of a drainer and a control mechanism are arranged.

Specifically, in some embodiments, the water collecting tray 10 and the screw cap 50 are installed in the water tank, the pump cap 40 is disposed outside the water tank, the screw cap 50 protrudes out of the water tank through the water outlet, and the screw cap 50 and the pump cap 40 are fixed by a screw thread.

As for other components, as shown in fig. 2, a shower 60 is installed on the drip pan 10; as shown in fig. 3, the filter cartridge 30 is sleeved under the slag separating basket 20, and then the slag separating basket 20 and the filter cartridge 30 are installed in the pump cover 40 from the water tank. The valve core and control mechanism of the drainer are mounted on the pump cover 40, and the impeller and motor of the washing pump 70 are also fixed on the pump cover 40.

Due to different terms of enterprises, the slag separating basket 20 is also called a cup, and the pump cover 40 is also called a cup, which is similar in structure and function.

As for the working principle of the cleaning machine, specifically, the following is:

first, the shower unit 60 sprays water to wash away the contaminants, the water drops to the bottom of the sump together with the contaminants, and the contaminants flow toward the drip tray 10 together with the water.

Then, the top structure of the slag separating basket 20 filters the dirt, so that large dirt is prevented from entering the slag separating basket 20; the water and smaller contaminants then enter the skimmer basket 20.

Subsequently, the water and the smaller contaminants are sequentially filtered by the slag separating basket 20 and the filter cylinder 30 to form water containing less impurities, and the water containing less impurities enters the pump cover 40 after passing through the filter cylinder 30.

Then, the water with less impurities enters the impeller cavity 71 on the pump cover 40, and then the water is driven by the impeller of the washing pump 70 and flows to the sprayer 60 through the water flow channel on the water collecting disc 10, so that the water is circularly cleaned and recycled.

When the washing is completed, the impeller of the washing pump 70 stops rotating, the water is not delivered to the shower unit 60, and then the control mechanism of the drainer controls the valve core to operate, and the water is discharged from the pump cover 40.

Since the sewage in the water is not usually blocked, the water can be directly discharged from the bottom of the slag separating basket 20 and does not need to be completely filtered by the filter cartridge 30.

At the same time, as the water level drops, the water from the sprinkler 60 and impeller chamber 71 also flows in the opposite direction, tending to exit the pump cover 40 at a low point.

Although the above discussion has embodied the main improvements of the present embodiment, it is necessary to further describe the improvements of the present embodiment in detail.
