Description

Technical Field

[0001] The utility model relates to the technical field of filtering and removing impurities from a washing machine water inlet, in particular to a filtering and removing impurities device for a washing machine water inlet. Background Art

[0002] A washing machine is a cleaning appliance that uses electrical energy to generate mechanical action to wash clothes. It is divided into two categories according to its rated washing capacity: household and collective. China stipulates that washing capacity below 6 kg is a household washing machine: a household washing machine is mainly composed of a cabinet, a washing and dehydrating barrel (some washing and dehydrating barrels are separate), a transmission and control system, etc., and some are also equipped with a heating device.

[0003] At present, there are filters at the water inlet of washing machines to prevent impurities in the water. The filters are directly made inside the water inlet. This method does not have much problem when the water quality is good, but for example, in Africa and areas with relatively scarce water resources, the water source is not very good, and the water contains a lot of silt and impurities. The filter installed at the water inlet of the existing washing machine is made inside the water inlet. If there are many impurities in the water, the filter will be blocked, making it impossible to inlet water. When cleaning, the water inlet pipe must be removed, and the impurities inside the water inlet interface are not convenient to remove. For this reason, a washing machine water inlet process impurity removal device is designed to solve the above problems. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a washing machine water inlet filtering and removing impurities device, which is characterized by comprising a filter box, an inlet pipe, an outlet pipe, an impurity discharge pipe, an impurity discharge cover, a bottom clamping block, and a filter assembly. The water inlet arranged at one end of the filter box is connected to the water inlet pipe, the water outlet arranged at the other end of the filter box is installed with the outlet pipe, the bottom clamping block arranged on the bottom surface of the inner cavity of the filter box is connected to the filter assembly, the impurity discharge port arranged at the bottom of the filter box is connected to the impurity discharge pipe, the end of the impurity discharge pipe is provided with a thread and is threadedly connected to the impurity discharge cover,

[0005] The filter assembly is composed of a first filter screen plate, a second filter screen plate, a mounting plate, mounting nails and a handle. The first filter screen plate is mounted on one end below the mounting plate, and the second filter screen plate is mounted on the other end below the mounting plate. A mounting handle is provided on the mounting plate. Both sides of the mounting plate are connected to the filter box through mounting nails. The bottoms of the first filter screen plate and the second filter screen plate are clamped in the clamping groove of the bottom clamping block.

[0006] The filtering aperture of the first filter screen plate is larger than the filtering aperture of the second filter screen plate.

[0007] The mounting plate is arranged in a T-shaped structure, and a sealing ring is arranged at the connection between the mounting plate and the mounting groove notch on the filter box.

[0008] Furthermore, an observation window is provided on the impurity discharge pipe, so that the impurities in the impurity discharge pipe can be checked and cleaned in time.

[0009] Furthermore, the two impurity discharge ports are arranged at the bottom of the filter box, one is located at the front side of the first filter screen plate, and the other is located between the first filter screen plate and the second filter screen plate.

[0010] Furthermore, the water inlet pipe is connected to the water outlet of the water supply system, and the water outlet pipe is connected to the water inlet of the washing machine.

[0011] Beneficial effects of the utility model:

[0012] The utility model designs a filter box to filter the water delivered to the washing machine. The first filter screen in the filter assembly performs preliminary filtration on the water, and then fine filtration is performed by the second filter screen to filter out impurities such as silt and floccules in the water, thereby improving the filtration effect.

[0013] The filtered mud and sand materials will accumulate in the drainage pipe, and the drainage cover is threadedly connected to the drainage pipe mouth, which makes it easy to clean the drainage pipe. The mounting plate of the filter assembly is installed on the filter box through mounting nails. The filter assembly is taken out regularly to clean the first filter screen plate and the second filter screen plate to prevent the accumulation of flocs and other impurities to block the filter screen plates and affect the filtration and water delivery conditions. The filter assembly is simple to disassemble and install and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
