The water inlet cavity is connected to the first spraying cavity through the spraying water inlet; the water in the water inlet cavity can enter the first spraying cavity through the spraying water inlet.

[0027] (1) The first spray chamber, the pressurized flow channel and the second spray chamber are sequentially arranged along the water inlet direction of the spray body and are connected; a portion of the water inside the spray body can be sprayed out through the first spray chamber and the first spray hole; another portion of the water inside the spray body is pressurized through the pressurized flow channel, enters the second spray chamber and is sprayed out through the second spray hole, so that the pressure of the water sprayed from the first spray hole and the pressure of the water sprayed from the second spray hole both have strong flushing and cleaning power, the flushing and cleaning power is evenly distributed, and the spray cleaning coverage is large; the cleaning is thorough and sufficient, and the cleaning efficiency is high, which solves the problem of uneven distribution of flushing and cleaning power of existing spray parts resulting in incomplete cleaning and low efficiency, and solves the problem of narrow cleaning coverage of existing spray parts that cannot effectively and comprehensively clean the entire filter screen;

[0028] (2) There is no need to add an additional booster pump or increase the flow rate of the water inlet valve. The pressure of the second spray chamber is increased by the booster flow channel. Combined with the diversion effect of the guide wall, the water in the second spray chamber is radially sprayed out through the second spray hole, which greatly increases the spray cleaning coverage of the spray part and improves the flushing force of the spray cleaning, thereby achieving effective cleaning. The aperture of the first spray hole is smaller than or equal to the aperture of the second spray hole. Impurities in the water can be discharged through the second spray hole, avoiding the problem that the spray hole is too small and impurities clog the spray hole, resulting in the failure of the spray part. The water in the second spray chamber has a greater flushing force after being sprayed out through the second spray hole, thereby improving the flushing and cleaning effect.

[0029] (3) The spray element is opened intermittently, and the time when the spray water inlet valve is in the open state is shorter than the time when the spray water inlet valve is in the closed state. The water that enters the spray chamber first and the water that enters the spray chamber later are squeezed together. Combined with the pressurization effect of the pressurized flow channel, the water sprayed from the spray hole has a greater flushing and cleaning power. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] In the prior art, the surface of the filter is mainly cleaned by water sprayed from a spray element, thereby separating dust or lint attached to the filter from the filter. However, due to the unreasonable structural design of the spray element and the influence of the position and aperture size of the spray holes, the water pressure sprayed from the spray holes near the water inlet end is high and the scouring and cleaning power is strong, while the water pressure sprayed from the spray holes far from the water inlet end is low and the scouring and cleaning power is weak. The scouring and cleaning power is unevenly distributed, the cleaning coverage is narrow, resulting in incomplete and insufficient cleaning, low cleaning efficiency, long cleaning time, and poor user experience.

[0051] The present invention creatively provides a spray element, comprising a spray body, a spray water inlet formed at one end of the spray body, a first spray chamber, a pressurized flow channel, and a second spray chamber formed inside the spray body, the first spray chamber, the pressurized flow channel, and the second spray chamber being sequentially arranged and connected along the water inlet direction of the spray body; a first spray hole formed on a side wall of the first spray chamber, the first spray hole being connected to the first spray chamber; a second spray hole formed on a side wall of the second spray chamber, the second spray hole being connected to the second spray chamber;

[0053] The pressure of the water sprayed from the first spray hole and the pressure of the water sprayed from the second spray hole both have strong flushing cleaning power, the flushing cleaning power is evenly distributed, and the spray cleaning coverage is large; the cleaning is thorough and sufficient, and the cleaning efficiency is high, which solves the problem of uneven distribution of flushing cleaning power of existing spray parts resulting in incomplete cleaning and low efficiency, and solves the problem that the cleaning coverage of existing spray parts is narrow and cannot effectively and comprehensively clean the entire filter screen.

[0054] <Spray parts>

[0055] As shown in Figure 1 to Figure 4cAs shown, this embodiment provides a spray element 1, including a spray body, a spray water inlet formed at one end of the spray body, and a first spray chamber 121, a pressurizing flow channel 123, and a second spray chamber 122 formed inside the spray body. The first spray chamber 121, the pressurizing flow channel 123, and the second spray chamber 122 are arranged in sequence along the water inlet direction of the spray body and are connected. Water in the first spray chamber 121 can enter the second spray chamber 122 through the pressurizing flow channel 123; the pressurizing flow channel 123 has a pressurizing effect, and adjusting the cross-sectional area of ​​the pressurizing flow channel 123 can adjust the water pressure in the second spray chamber 122;

[0056] A plurality of first spray holes 1311 are formed on the sidewall of the first spray chamber 121. The plurality of first spray holes 1311 are alternately arranged along the sidewall of the first spray chamber 121. The first spray holes 1311 are connected to the first spray chamber 121, and water in the first spray chamber 121 can be sprayed out through the first spray holes 1311. A second spray hole 1321 is formed on the sidewall of the second spray chamber 122. The plurality of second spray holes 1321 are alternately arranged along the sidewall of the second spray chamber 122. The second spray holes 1321 are connected to the second spray chamber 122, and water in the second spray chamber 122 can be sprayed out through the second spray holes 1321.

[0057] The water outside the spray body can enter the spray body through the spray water inlet, and a part of the water inside the spray body can be sprayed out through the first spray chamber 121 and the first spray hole 1311; another part of the water inside the spray body enters the second spray chamber 122 through the boosting channel 123, and the water in the second spray chamber 122 is sprayed out through the second spray hole 1321.

[0058] Specifically, the first spray chamber 121 and the boosting channel 123 can both be structures with equal cross-sections, and the cross-sectional area of ​​the first spray chamber 121 is larger than the cross-sectional area of ​​the boosting channel 123; or the first spray chamber 121 and the boosting channel 123 can both be structures with unequal cross-sections, and the minimum cross-sectional area of ​​the first spray chamber 121 is larger than the maximum cross-sectional area of ​​the boosting channel 123, or the average cross-sectional area of ​​the first spray chamber 121 is larger than the average cross-sectional area of ​​the boosting channel 123; the boosting channel 123 can change the internal structure of the spray body, thereby changing the pressure of water in the spray chamber.

[0059] To address the problem of impurities easily clogging the spray holes when the water entering the spray chamber contains impurities, this embodiment proposes that the aperture of the first spray hole 1311 is d1, and the aperture of the second spray hole 1321 is d2, satisfying d1≤d2. When impurities enter the first spray chamber 121, under the pressure of the first spray chamber 121, the impurities enter the second spray chamber 122 along with the water. The impurities in the water can be discharged through the second spray hole 1321, avoiding the problem of the spray hole being too small and the impurities clogging the spray hole, which would cause the spray body to lose its function. After being sprayed out of the second spray hole 1321, the water in the second spray chamber 122 has a greater flushing force, thereby improving the flushing and cleaning effect.

[0060] Preferably, 0.5mm≤d1≤2mm.

[0061] The first spray hole 1311 accumulates power, which can increase the pressure of the fluid in the first spray chamber 121 and make its spray intensity greater; the second spray hole 1321 can spray more fluid and increase the force; when the spray element 1 is used in clothing processing equipment, the spray element 1 can flush the hair, fiber and other substances on the filter screen 22, thereby better protecting the clothes in the washing drum.

[0062] Furthermore, a guide wall 1322 is formed at one end of the second spray chamber 122 away from the pressurized flow channel 123; the water in the second spray chamber 122 changes its flow direction when passing through the guide wall 1322, and then is sprayed out through the second spray hole 1321; the water that first enters the second spray chamber 122 returns after being acted upon by the guide wall 1322 and collides with the water that enters the second spray chamber 122 later, and then is sprayed out through the second spray hole 1321, which is beneficial to the separation of impurities from water and accelerates the discharge of impurities.

[0063] To address the problem that the improper positioning of the spray holes results in the dispersion of the water sprayed from the spray holes and weak flushing and cleaning power, this embodiment proposes that the first spray chamber 121 includes a first spray wall 131, which is formed with a plurality of first spray holes 1311 arranged alternately.

[0064] The second spray chamber 122 includes a second spray wall 132 , which is disposed on the same side as the first spray wall 131 and has a plurality of second spray holes 1321 disposed alternately therebetween.

[0065] Furthermore, the first spray wall 131 and the second spray wall 132 both extend along the water inlet direction of the spray body, and the first spray wall 131, the side wall of the pressurizing flow channel 123, and the second spray wall 132 are sequentially connected; the spray coverage area of ​​the second spray hole 1321 is close to the spray coverage area of ​​the first spray hole 1311;

[0066] Multiple first spray holes 1311 are located near the pressurized flow channel 123 and are alternately arranged along the length and width of the spray body. A portion of the water entering the first spray chamber 121 can be directly sprayed out through the first spray holes 1311. The water sprayed from the first spray holes 1311 at different locations has different directions. This allows the water sprayed from the first spray holes 1311 to have a wide coverage area and strong flushing force, thereby improving the spray cleaning effect.

[0067] Multiple second spray holes 1321 are located near the pressurized flow channel 123. Water that first enters the second spray chamber 122 is acted upon by the guide wall 1322 and then returns and collides with water that enters the second spray chamber 122 later before being sprayed out through the second spray holes 1321. The guide wall 1322 causes the water that enters the second spray chamber 122 to return in the opposite direction and be sprayed radially through the second spray holes 1321, thereby greatly increasing the spray cleaning coverage of the spray element 1 and enhancing the scouring force of the spray cleaning, thereby achieving effective cleaning.

[0068] The water in the second spray chamber 122 is sprayed obliquely downward through the second spray hole 1321 , which can prevent the filter 22 and other components from not being flushed properly, and can also increase the flushing force.

[0069] In response to the problem that the water sprayed from the second spray hole 1321 is dispersed and concentrated, this embodiment proposes that the multiple second spray holes 1321 include a second spray hole A and a second spray hole B, and the second spray hole A and the second spray hole B are symmetrically arranged relative to the symmetry axis of the spray body, and the distance between the hole center of the second spray hole A and the hole center of the second spray hole B and the guide wall 1322 is h, satisfying 0.5mm≤h≤8mm.

[0070] In view of the problems of the existing complex structure and great difficulty in processing of the spray part 1, the present embodiment proposes that the spray body includes a cover body 11 and a box body 12, the cover body 11 and the box body 12 are connected to form a first spray chamber 121, a pressurized flow channel 123 and a second spray chamber 122; specifically, the cover body 11 and the box body 12 can be fixedly connected by a snap-fit ​​structure and sealed by a sealing ring; the side wall of the box body 12 close to the cover body 11 is formed with an opening, and a part of the side wall of the box body 12 away from the cover body 11 is extended in a direction away from the cover body 11 The first spray wall 131 protrudes and forms the side wall of the boosting flow channel 123 and the second spray wall 132. The first spray wall 131, the side wall of the boosting flow channel 123, and the second spray wall 132 are symmetrically arranged with respect to the symmetry axis of the box body 12. First spray holes 1311 are formed on both sides of the first spray wall 131 away from the first spray cavity 121 and symmetrically with respect to the symmetry axis of the box body 12. The second spray holes A and the second spray holes B are oriented in a direction away from the symmetry axis of the box body 12 and close to the first spray wall 131.

[0071] The spray element 1 further includes a water inlet 14, which is connected to the box body 12 and forms a water inlet cavity 141. The water inlet cavity 141 is connected to the first spray cavity 121 through a spray water inlet. The water inlet end of the water inlet cavity 141 is connected to the spray water inlet valve 24 or an external water pipe 23. External water can enter the water inlet cavity 141 through the spray water inlet valve 24 or the water pipe 23; water in the water inlet cavity 141 can enter the first spray cavity 121 through the spray water inlet.

[0072] The spray element 1 also includes a mounting portion 15, which is formed with a mounting hole 151, and the mounting hole 151 is used to fix the spray element 1; specifically, the water inlet portion 14 is a tubular structure, and the mounting portion 15 is a plate-type structure. The mounting portion 15 is formed with a through hole, and the water inlet portion 14 is arranged in the through hole. The axial direction of the water inlet portion 14 is perpendicular to the mounting portion 15, and the water inlet end and the water outlet end of the water inlet portion 14 are respectively on both sides of the mounting portion 15; the extension direction of the box body 12 is consistent with the axial direction of the water inlet portion 14.

[0073] Preferably, the water inlet portion 14 , the mounting portion 15 and the box body 12 are integrally formed.

[0074] The spray element 1 in this embodiment can be used in washing and rinsing, so that the substances attached to the surface of components such as the filter screen 22 can be cleaned off under the impact force of the fluid, so it is widely used; the boosting flow channel 123 mainly changes the flow area of ​​the fluid. Under a certain fluid flow rate and flow velocity, the boosting flow channel 123 has a pressurizing effect on the fluid.

[0075] <Clothing treatment equipment>

[0076] like Figure 5 As shown, this embodiment also proposes a clothes processing device, which includes an outer tube 21, a filter 22, a spray water inlet valve 24, a controller and the above-mentioned spray element 1, the outer tube 21 is formed with an outer tube air outlet, the filter 22 is arranged at the outer tube air outlet, the spray element 1 is arranged above the filter 22 and close to the filter 22, the spray water inlet valve 24 is connected to the water inlet end of the water inlet chamber 141; the spray water inlet valve 24 is a solenoid valve and is electrically connected to the controller; specifically, the filter 22 is a curved surface structure of the washing chamber concave to the outer tube 21; the outer tube air outlet is arranged on the outer The peripheral side wall of the cylinder 21 is close to one end of the bottom wall of the outer cylinder 21; the spray element 1 is constructed so that water is sprayed from the spray element 1 in a divergent and multi-directional manner toward the filter 22; the use of the spray element 1 to clean the hair debris on the filter 22 has a simple structure, good cleaning effect and fast cleaning speed, solving the problems of cumbersome manual hair debris cleaning process, slow cleaning speed and poor cleaning effect, expanding the cleaning coverage, cleaning more thoroughly, avoiding the situation where some hair debris is missed, so that the filter 22 maintains a high filtering effect, reduces wind resistance, effectively improves the drying efficiency, and ensures the cleanliness of the drying flow path and stable operation;

[0077] A first spray wall 131 and a second spray wall 132 are formed on one side of the spray body close to the filter 22. The structures of the first spray wall 131 and the second spray wall 132 are adapted to the structure of the filter 22. The positions of the multiple first spray holes 1311 are divergent and the axial direction of each first spray hole 1311 is at a certain angle to the curved surface structure of the filter 22. After water is sprayed out from the first spray holes 1311, it can cover the surface of the filter 22 to the maximum extent, making the cleaning of the hair debris on the filter 22 more thorough.

[0078] Preferably, the spray member is a cantilever structure extending along the diameter of the outer cylinder air outlet. The first spray hole 1311 is designed so that the water sprayed therefrom can cover a portion of the filter screen 22, and the second spray hole 1321 is designed so that the water sprayed therefrom can cover another portion of the filter screen 22. In this way, the first spray hole 1311 and the second spray hole 1321 can cover and clean the filter screen 22.

[0079] The sidewall of the outer tube air outlet is formed with a mounting slot, through which the spray element 1 passes and is positioned above the filter 22. The mounting portion 15 is removably connected to the sidewall of the outer tube air outlet, facilitating installation, removal, and replacement of the spray element 1. This connection is typically a latch-type or threaded connection. A sealing ring is provided between the mounting portion 15 and the sidewall of the outer tube air outlet to provide a seal and prevent water from escaping the mounting slot and posing a safety hazard.

[0080] When the clothes processing device operates in the self-cleaning mode of the filter 22 , the spray element 1 cleans the filter 22 , saving space, materials and water.

[0081] <Control method>

[0082] like Figure 6 As shown, this embodiment also proposes a control method for the above-mentioned clothes processing device, wherein the clothes processing device includes a self-cleaning mode for the filter 22;

[0083] When the clothes processing device runs the self-cleaning mode of the filter 22, the spray water inlet valve 24 is controlled to run the spray program to make the spray element 1 clean the filter 22 until the total spraying time of the spray element 1 reaches the preset spraying time;

[0084] The spraying program includes the spraying water inlet valve 24 being in an open state and the spraying water inlet valve 24 being in a closed state, and the duration of the spraying water inlet valve 24 being in the open state is shorter than the duration of the spraying water inlet valve 24 being in the closed state.

[0085] Further, controlling the spray water inlet valve 24 to run the spray program includes:

[0086] Control the spray water inlet valve 24 to open and time;

[0087] When the duration T10 of the spray water inlet valve 24 being open reaches the first preset duration T11, the spray water inlet valve 24 is controlled to be closed and timing is started;

[0088] When the duration T20 of the spray water inlet valve 24 being closed reaches the second preset duration T21, the spray water inlet valve 24 is controlled to be opened and timing is started;

[0089] When the duration T30 of the spray water inlet valve 24 being open reaches the third preset duration T31, the spray water inlet valve 24 is controlled to be closed;

[0090] Among them, T11≤2s≤T21≤3s≤T31.

[0091] When T11≤T21≤3s, the first preset time length T11 is close to the second preset time length T21, and the water flow in the first water flow has not been completely discharged from the spray body.
