The rain-type filtering component 3 is a T-shaped nozzle 31, a water outlet hole 32 with a downward direction is formed in the T-shaped nozzle 31, the T-shaped nozzle 31 is located at an air suction opening 42 of the air circulation pipeline 4, when air carrying hair and dust passes through the T-shaped nozzle 31, water is sprayed out of the water outlet hole 32 in the T-shaped nozzle 31, the water takes away air which just enters the air suction opening 42, and the purpose of filtering the air is achieved.
Referring to fig. 1, 4 and 6, in the embodiment of the present invention, the water circulation pipeline 2 is communicated with the air circulation pipeline 4 at the rain filter assembly 3, and the water circulation pipeline 2 can supply water to the rain filter assembly 3, so that the water in the water circulation pipeline 2 is sprayed out of the rain filter assembly 3 to filter the air in the air circulation pipeline 4.
In this embodiment, the water circulation pipeline 2 mainly includes a parking channel a section 21, a parking channel B section 22, a parking channel C section 23 and a drain pipe 24, the whole water circulation pipeline 2 is located at the lower end of the outer cylinder 12, one end of the parking channel a section 21 is arranged corresponding to the deluge-type filtering component 3, the other end of the parking channel a section 21 is communicated with the parking channel B section 22, and the parking channel B section 22 is communicated with the parking channel C section 23 and the drain pipe 24 through a three-way valve 27.
The parking channel A section 21 is mainly responsible for collecting water falling from the rain filter assembly 3 and collecting water with hair and dust in the parking channel A section, the parking channel B section 22 is mainly used for collecting water filtered after passing through the parking channel A section 21, the parking channel B section is communicated with the parking channel C section 23 and the drain valve 24 through the three-way valve 27, when the rain filter assembly 3 needs to filter air in the air circulation pipeline 4, the parking channel B section 22 is communicated with the parking channel C section 23 to supply water for the rain filter assembly 3, and after the water in the water circulation pipeline 2 is filtered for multiple times and the dust content in the water is high, the parking channel B section 22 is communicated with the drain pipe 24 to discharge the water.
In order to achieve better effect, the water circulation pipeline 2 is provided with a water inlet valve 28 on the box body 1, the water inlet valve 28 is connected with a water source at the position where the washing machine is installed, the water inlet valve 28 is communicated with a water inlet 29 through a water pipe inside the washing machine, the water inlet 29 is located at the upper end of the deluge type filtering component 3, when the washing machine needs to feed water, a user opens the water inlet valve 28, and the water enters the parking channel A section 21 from the water inlet 29 and enters the water circulation pipeline 2 to provide a water source for the deluge type filtering component 3.
The water circulation pipeline 2 is provided with the water level controller 6, because the hair and the dust are attached to the clothes, the hair and the dust are difficult to separate from the clothes after the clothes are wetted, therefore, in order to prevent water from entering the inner drum 11 to contact the clothes, the water level controller 6 is arranged to control the water injection amount of the water inlet valve 28 to the water circulation pipeline 2, the highest water level in the water circulation pipeline 2 is always kept to be not more than the lowest point of the outer drum 12, and the situation that the hair and the dust are difficult to separate after the clothes are wetted is effectively avoided.
Referring to fig. 1 and 5, the deluge filter assembly 3 is a T-shaped nozzle 31, a downwardly-oriented water outlet hole 32 is formed in the T-shaped nozzle 31, the T-shaped nozzle 31 is hollow, the T-shaped nozzle 31 is communicated with the parking channel C section 23 of the water circulation pipeline 2, the diameter of the T-shaped nozzle 31 is slightly smaller than that of the parking channel C section 23, the lower end of the T-shaped nozzle 31 can be inserted into the parking channel C section 23, the T-shaped nozzle 31 is fastened with the parking channel C section 23 and is communicated with the inside, water in the water circulation pipeline 2 flows out of the water outlet hole 32 of the T-shaped nozzle 31 under the action of the water pump 26, the water outlet hole 32 of the T-shaped nozzle 31 is located in the air circulation pipeline 2, and the water outlet hole 32 can cover air passing through the air circulation pipeline 4 to the greatest extent at a position above the diameter of the air circulation pipeline 2.
When the washing machine is in operation, the inner cylinder 11 rotates relative to the outer cylinder 12, the blowing port 41 of the air circulation pipeline 4 blows air into the inner cylinder 11 under the action of the centrifugal fan 43, the air suction port 42 at the other end of the air circulation pipeline 4 sucks air in the inner cylinder 11 for filtering clothes, because hairs and dust on the clothes are attached to the air, when the air enters the air circulation pipeline 4 again from the air suction port 42, the T-shaped nozzle 31 sprays water flow from the water outlet hole 32 after water is supplied to the water circulation pipeline 2, the hairs and dust which just enter the air in the air circulation pipeline 4 are taken away by the water flow, at the moment, clean air enters the air circulation pipeline 4 again, and high-speed air is blown into the inner cylinder 11 again from the blowing port 41.
The water with hair and dust flows into the parking channel a section 31, and because the water with hair and dust can not be used for filtering air again, a filter assembly 25 is arranged between the parking channel a section 31 and the parking channel B section 32, the filter assembly 25 mainly comprises a filter chamber 251 and a filter 252, the filter chamber 251 is a space with a certain volume, and the filter 252 can block hair in the water from passing through and prevent the hair from blocking the water outlet hole 32 of the T-shaped nozzle 31.
When water carrying hair and dust passes through the filter assembly 25, dust and hair with larger particles are blocked in the filter cavity 251 by the filter 252, the filtered water flows into the parking channel B section 22 from the parking channel a section 21, and under the action of the water pump 26, the filtered water flows into the parking channel C section 23 from the parking channel B section 22 through the three-way valve 27 to flow towards the T-shaped nozzle 31 and flows out from the water outlet hole 32 to take away hair and dust in air again, so that an air filtering cycle is completed.
Referring to fig. 1 and 7, dust and hair with different sizes may be attached to clothes, when the dust and hair pass through the T-shaped nozzle 31, the first filtered water may filter the air that has just entered the air circulation pipeline 4, take away the hair and dust therein, and flow into the parking channel a section 21, but is limited by the filter 252 of the filter assembly 25, when the small-particle dust passes through the filter 252, because the particles are too small, the dust cannot be blocked by the filter 252, and may reenter the next air filtration cycle with the water flow, after many times, the small-particle dust in the water is too much collected, and the filtering capability of the water is reduced, therefore, the turbidity sensor 253 is disposed in the water circulation pipeline 2, the turbidity sensor 253 can measure the content of the small-particle dust in the filtered water, when the content of the small-particle dust in the water is too high, and the requirement for filtering the air in the air circulation pipeline 4 cannot be met, the parking channel B section 22 is communicated with the drain pipe 24 through the three-way valve 27, water is discharged out of the washing machine from the drain pipe 24, and water is injected into the washing machine again through the water inlet valve 28, so that water resources are utilized to the maximum extent, waste of water resources is reduced, the resource utilization rate is improved, and the cost of users is reduced.
