DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in this application will not be described separately.

[0044] In the following description, the terms "first\second\..." are only used to distinguish different objects, and do not mean that the objects have the same or related points. It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the specific corresponding schematic diagrams, which may be the left and right directions in normal use or not.

[0045] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.

[0046] The embodiment of the present application provides a spray cover 100. The spray cover can be used in any scenario. For example, it can be used in a washing device, which can be a clothes processing device, a fruit washing machine, a dishwasher, a shoe washing machine, etc. The washing device has a washing drum, which can rotate.

[0047] In the embodiment of the present application, description is made by taking the spray cover used in a clothing processing device as an example.

[0048] The embodiment of the present application further provides a clothes processing device, including a washing drum, a workbench 200 and a spray cover 100 of any embodiment of the present application.

[0049] The washing tub has a clothes processing chamber, and the top end of the clothes processing chamber is open.

[0050] It is understandable that in some embodiments, the laundry processing device has only a washing drum, and the washing drum holds water by itself, that is, in this embodiment, the washing drum can hold both laundry and water, in which case the washing drum can be referred to as a non-hole washing drum. In other embodiments, the laundry processing device includes an outer barrel, which is mounted outside the washing drum, and the outer barrel is used to hold water required for washing laundry, and the washing drum is used to hold laundry. In this embodiment, the washing drum holds water by the outer barrel, and the washing drum can also be referred to as a perforated washing drum. In some other embodiments, in the embodiment with an outer barrel, water can also be held by the washing drum itself, in which case the washing drum can also be referred to as a non-hole washing drum.

[0051] The workbench 200 is arranged above the washing tub, and the workbench 200 has a clothes loading port 200A. That is, the clothes processing device of this solution is suitable for taking and placing clothes from above.

[0052] See also Figure 1 The spray cover 100 includes a cover body 11 and a spray nozzle 12 .

[0053] Among them, see Figure 5 The cover body 11 has a water inlet interface 11A and a water containing cavity 11B, and the water containing cavity 11B has an opening 11C.

[0054] See also Figure 1 , Figure 2 as well as Figure 6 The spray nozzle 12 has a water outlet gap 12A. The length of the water outlet gap 12A is at least twice as long as the width, for example, 2 to 5 times.

[0055] The spray nozzle 12 and the cover body 11 are of a split structure, that is, the two are two independent components and are not an integrally formed structure.

[0056] The spray nozzle 12 closes the opening 11C, and the water chamber 11B communicates with the water inlet interface 11A and the water outlet gap 12A, so that the water in the water chamber 11B is sprayed out through the water outlet gap 12A. For example, the water outlet gap 12A is used to spray water onto the wall of the washing drum of the laundry processing device.

[0057] The spray cover 100 of the embodiment of the present application can have a waterfall-like water flow effect when the water is sprayed out from the spray nozzle 12, and can also have a pressurizing effect, which helps the water to be quickly sprayed out from the water outlet gap 12A, thereby enhancing the impact effect of the water on the impact object such as the washing drum, and improving the cleaning effect; by designing the cover body 11 and the spray nozzle 12 as a split type, the cover body 11 and the spray nozzle 12 can be processed separately, for example, by injection molding respectively, which can reduce the complexity of the injection mold and the difficulty of demolding, that is, reduce the manufacturing difficulty of the spray cover 100, and reduce the production cost of the spray cover 100.

[0058] Exemplarily, the water outlet gap 12A is used to spray water toward the wall of the washing tub, that is, the water sprayed from the water outlet gap 12A is directly sprayed toward the wall of the washing tub.

[0059] It is understandable that when the clothes processing device is in use, foam, lint and the like will inevitably remain on the circumferential inner wall of the washing drum. If they are not cleaned in time, they will contaminate the clothes to be washed next time.

[0060] In the clothing processing device provided in the embodiment of the present application, the water flow sprayed from the water outlet gap 12A can wash away impurities such as foam attached to the wall of the washing drum, and clean the wall of the washing drum in all directions under the rotation of the washing drum, thereby realizing automatic cleaning of the washing drum.

[0061] It should be noted that the spraying time of the spray nozzle 12 is not limited, for example, water can be sprayed during water intake or washing, which helps to spray and wet clothes. Spraying water during or after drainage helps to clean the wall of the washing drum.

[0062] See also Figure 8 and Fig. 9The workbench 200 has a boss 2001 protruding toward the center of the clothing delivery port 200A, and the boss 2001 has an opening. Specifically, the boss 2001 has an opening obliquely below the axis of the clothing delivery port 200A. The spray cover 100 is disposed at the opening.

[0063] In this embodiment, the cover body 11 of the spray cover 100 is arranged to be tilted from top to bottom approximately in a direction away from the axis of the washing tub. Specifically, the boss 2001 is located at the rear of the clothing inlet 200A, and the lower end of the cover body 11 is tilted backward, so that the upper end of the cover body 11 is closer to the front and the lower end is closer to the back. In this way, the user can see the cover body 11 of the spray cover 100.

[0064] For example, see Figure 1 , Figure 2 as well as Figure 6 The outer surface of the spray nozzle 12 on the side away from the water chamber 11B has a first plane 12B, and the outlet of the water outlet gap 12A is located on the first plane 12B. In other words, the end of the water outlet gap 12A does not exceed the first plane 12B, which is conducive to improving the appearance of the spray nozzle 12.

[0065] For example, see Figure 4 The spray nozzle 12 includes a plate body 121 and a guide sleeve 122. The guide sleeve 122 is disposed on the inner side of the plate body 121, that is, on the side of the plate body 121 facing the water chamber 11B, and the two together define a water outlet gap 12A. The guide sleeve 122 is in the shape of a hollow flat cylinder, and its cross-sectional shape is the same or similar to the shape of the water outlet gap 12A.

[0066] The outer surface of the plate body 121 defines the first plane 12B. The outlet of the water outlet gap 12A penetrates the plate body 121. The water flows into the guide sleeve 122 from the end of the guide sleeve 122 away from the plate body 121, flows through the guide sleeve 122, and then sprays out from the outlet on the plate body 121. In this embodiment, the guide sleeve 122 is conducive to guiding the water flow.

[0067] For example, see Figure 6 and Figure 7 The guide sleeve 122 has first side walls 1221 on opposite sides along the length direction of the water outlet gap 12A. The two first side walls 1221 extend away from each other along the water flow direction. The two first side walls 1221 are not parallel and are roughly trumpet-shaped. Figure 3, the angle Φ of the two first side walls 1221 is greater than 0° and less than 180°, that is, 0°<Φ<180°. In this embodiment, the two first side walls 1221 are conducive to making the water flow sprayed from the water outlet gap 12A present a fan-shaped water flow, and the water flow sprayed from the water outlet gap 12A can have a larger water outlet range in the height direction of the drum wall, which is conducive to achieving a more comprehensive cleaning of the drum wall of the washing drum.

[0068] It should be noted that Figure 3 In the figure, two dotted lines corresponding to the angle Φ indicate the extension directions of the two first side walls 1221.

[0069] Exemplarily, the angle Φ between the two first side walls 1221 is 2° to 30°, that is, 2°<Φ<30°, for example, 2°, 5°, 10°, 13°, 15°, 18°, 20°, 24°, 25°, 27°, 29°, 30°, etc. The angle Φ is in a suitable range, so that the water sprayed from the water outlet gap 12A can fully flush the wall of the washing tub 10 while also having good working stability, thereby reducing the probability of water splashing outside the washing tub 10 and affecting the safety performance of the clothes processing device 1.

[0070] For example, see Figure 6 and Figure 7 The guide sleeve 122 has second side walls 1222 on opposite sides along the width direction of the water outlet gap 12A. Fig. 9 The second side wall 1222 extends obliquely in a direction away from the axis of the washing tub, and is used for spraying water toward the tub wall of the washing tub. In this embodiment, the two second side walls 1222 are conducive to tilting the water flow toward the tub wall.

[0071] Exemplarily, the two second side walls 1222 may be arranged in parallel or may not be arranged in parallel.

[0072] For example, see Fig. 9 The angle β between the second side wall 1222 and the horizontal plane is 40°~75°, that is, 40°≤β≤80°, for example, 40°, 45°, 50°, 53°, 56°, 60°, 65°, 70°, 73°, 75°, etc.

[0073] It is understandable that if the angle β between the second side wall 1222 and the horizontal plane is too small, the water jetted from the water outlet gap 12A is likely to jet out of the washing tub, affecting the components outside the washing tub. If the angle β between the second side wall 1222 and the horizontal plane is too large, the water jetted from the water outlet gap 12A does not cover enough of the circumferential direction of the washing tub, and the circumferential inner side wall of the washing tub far from the bottom of the washing tub is likely not to be covered and cleaned by the water jet, thereby affecting the cleaning of the washing tub.

[0074] Therefore, in this embodiment, the angle β between the second side wall 1222 and the horizontal plane is appropriate, and the water flow sprayed from the water outlet gap 12A can clean the circumferential inner wall of the washing drum more comprehensively, and the water flow sprayed from the water outlet gap 12A will not spray to the outside of the washing drum, thereby increasing the working reliability of the clothing processing equipment.

[0075] For example, see Figure 1 , the length d2 of the water outlet gap 12A does not exceed 100 mm (millimeter), that is, d2≤100 mm; and / or, the width d1 of the water outlet gap 12A does not exceed 5 mm, that is, d1≤5 mm.

[0076] The length of the water outlet gap 12A can be, for example, 10 mm, 20 mm, 30 mm, 40 mm, 50 mm, 60 mm, 70 mm, 80 mm, 90 mm, 100 mm, etc.

[0077] The width of the water outlet gap 12A may be, for example, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, etc.

[0078] In this embodiment, the extension length of the water outlet gap 12A can help the water outlet gap 12A have a suitable water outlet range in the height direction of the drum wall of the washing drum. The width of the water outlet gap 12A is conducive to ensuring that the water flow is roughly in a flat waterfall shape, which can help increase the flow rate when the water flow rate is the same.

[0079] In some specific embodiments, the length d2 of the water outlet gap 12A is 10 mm to 25 mm, that is, 10 mm ≤ d2 ≤ 25 mm, for example, 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, 25 mm, etc. And / or, the width d1 of the water outlet gap 12A is 1 mm to 3 mm, that is, 1 mm ≤ d1 ≤ 3 mm, for example, 1 mm, 1.2 mm, 1.5 mm, 2 mm, 2.3 mm, 2.5 mm, 3 mm, etc. In this embodiment, the length range of the water outlet gap 12A can take into account both the compactness of the structure and the reasonable water outlet range. The width direction of the water outlet gap 12A allows for both effective water outlet and guaranteed water flow rate.

[0080] It should be noted that, in the embodiment of the present application, the length of the water outlet gap 12A can be understood as: Figure 6 , in the projection of the first plane 12B, the length of the line connecting the midpoints of the two first side walls 1221. The width of the water outlet gap 12A can be understood as: Figure 6 In the projection of the first plane 12B, when an imaginary cylinder is tangent to the two second side walls 1222 respectively, the corresponding diameter of the cylinder is the width of the water outlet gap 12A, and the widths of the water outlet gap 12A at different positions may be the same or different.

[0081] For example, see Figure 4 and Figure 5 The side wall around the opening 11C is provided with a step surface 11D, and the step surface 11D faces the side where the spray nozzle 12 is located. In other words, the step surface 11D is located in the water containing cavity 11B.

[0082] For example, see Figure 4 , the plate body 121 is arranged in the opening 11C, that is, in the projection of the plane where the plate body 121 is located, the projection of the plate body 121 is located in the projection of the opening 11C. The edge of the plate body 121 facing the side where the water chamber 11B is located is connected to the step surface 11D. In this way, the connection between the plate body 121 and the cover body 11 can be achieved. Since the plate body 121 is arranged in the opening 11C, the plate body 121 will not move relative to the cover body 11, thereby improving the connection reliability between the two. In addition, during assembly, it is conducive to the rapid positioning of the plate body 121 and improves the assembly efficiency.

[0083] It should be noted that, along the thickness direction of the plate body 121 , the outer surface of the plate body 121 may protrude outwardly from the surface of the cover body 11 around the opening 11C, or may be flush with the surface, or may be completely recessed into the opening 11C.

[0084] The connection method between the plate body 121 and the step surface 11D is not limited, for example, screw connection, bonding, clamping, etc.

[0085] Exemplarily, the plate body 121 and the step surface 11D are welded, for example, by ultrasonic welding, laser welding, etc. The welding method is conducive to improving the connection reliability between the plate body 121 and the step surface 11D, and is not prone to water leakage, thereby improving the sealing and waterproof performance of the connection between the two.

[0086] In some embodiments, before the plate body 121 is connected to the step surface 11D, triangular ribs are formed at the portion of the plate body 121 used to connect to the step surface 11D. During assembly, the triangular ribs rest against the step surface 11D. During welding, the triangular ribs melt, and the melted material is combined with the step surface 11D.

[0087] In some embodiments, the spray nozzle 12 includes a support rib, one end of which is connected to the plate body 121 or the guide sleeve 122, and the other end is in contact with the wall of the water chamber 11B. In this way, during the connection process between the plate body 121 and the cover body 11, even if the plate body 121 is squeezed inward, the support rib provides support for the plate body 121 and the guide sleeve 122, thereby improving the connection reliability between the plate body 121 and the cover body 11. In other embodiments, please refer to Figure 4The end of the guide sleeve 122 away from the plate body 121 abuts against the wall of the water containing chamber 11B. In this way, during the connection process between the plate body 121 and the cover body 11, even if the plate body 121 is squeezed inward, the guide sleeve 122 provides support for the plate body 121, thereby improving the connection reliability between the plate body 121 and the cover body 11.

[0088] In some embodiments, the spray nozzle 12 is an integrated structure. For example, the plate body 121 and the guide sleeve 122 are an integrated structure, for example, an integrated injection molding. The integrated injection molding can be a single-color injection molding or a double-color injection molding.

[0089] In some embodiments, the cover body 11 is an integrated structure, for example, an integrated injection molding, wherein the integrated injection molding can be a single-color injection molding, or a two-color injection molding, etc.

[0090] For example, see Figure 4 and Figure 5 The cover body 11 includes a cover plate 111 and a protrusion 112. The protrusion 112 protrudes from the surface of the cover plate 111 toward the first side of the cover plate 111 in the thickness direction, and the two define a water containing cavity 11B. The water inlet interface 11A is arranged on the second side of the cover plate 111 along the thickness direction. In other words, the surface of the first side of the cover plate 111 is the appearance surface of the cover plate 111, and the surface of the second side of the cover plate 111 in the thickness direction is the non-appearance surface. Therefore, the water inlet interface 11A is arranged on the second side of the cover plate 111 to avoid the water inlet interface 11A affecting the appearance of the spray cover 100.

[0091] For example, see Figure 1 and Figure 5 The surface of the first side of the cover plate 111 along the thickness direction is provided with a lighting installation area 111A, and the lighting installation area 111A is used to install a lighting. The lighting is used to provide a light source for the washing tub. In this embodiment, the spray cover 100 can not only provide an installation space for the lighting, but also spray water to the wall of the washing tub, thereby improving the compactness of the structure of the laundry processing device.

[0092] For example, see Figure 8 The boss 2001 is also provided with a detergent chamber 200C, so that the structure of the boss 2001 can be fully utilized to put detergent, which can improve the compactness of the structure of the workbench 200.

[0093] The number of detergent chambers 200C can be one, two or more. For example, one detergent chamber 200C is used to put in laundry liquid or laundry powder, and another detergent chamber 200C is used to put in softener. Of course, there can also be other detergent chambers 200C for putting in perfume, disinfectant, etc.

[0094] Exemplarily, the laundry treatment device includes a first water path and a second water path, wherein the first water path is connected to the water inlet interface 11A, and the second water path is connected to the detergent chamber 200C. The first water path is used to supply water to the water holding chamber 11B. The second water path is used to supply water to the detergent chamber 200C.

[0095] It should be noted that when there are multiple detergent chambers 200C, there are also multiple second water channels, and each detergent chamber 200C corresponds to one second water channel.

[0096] It should be noted that the first water path refers to the general term for the water flow path of the water supply chamber 11B, and the second water path refers to the general term for the water flow path of the water supply chamber 200C.

[0097] In some embodiments, the first water path and the second water path are independent of each other, so that the spray nozzle 12 and the detergent chamber 200C can be independently filled with water. In other words, the timing of water inlet to the first water path and the second water path can be independently controlled without affecting each other. This is conducive to independently controlling the timing of water inlet according to actual needs.

[0098] In other embodiments, the first water path and the second water path are interconnected so that water can be simultaneously supplied to the spray nozzle 12 and the detergent chamber 200C.

[0102] During the main water inlet, the water inlet valve 303 connects the water inlet with the first water outlet, and the switching valve 304 connects its inlet with the main detergent chamber, so that water can be fed into the main detergent chamber, and the detergent in the main detergent chamber is dissolved in the water and flows into the washing tub. When spraying is required, the water inlet valve 303 connects the water inlet with the first water outlet, and the switching valve 304 connects its inlet with the water holding chamber 11B, and at this time, spraying can be achieved through the spray nozzle 12.

[0103] In the last rinsing stage, the water inlet valve 303 connects the water inlet with the second water outlet, so that water can flow into the auxiliary detergent chamber, and the detergent in the auxiliary detergent chamber is dissolved in the water and flows into the washing tub.

[0104] In some other embodiments, the clothes processing device includes a diverter pipe head, which connects the first waterway, the second waterway and the first outlet, and is used to divert the water flow of the first outlet to the first waterway and the second waterway. In this embodiment, the diverter pipe head can realize the synchronous water inflow of the first waterway and the second waterway.

[0105] In the above embodiment, the flow dividing pipe head may be a three-way pipe.

[0106] In other embodiments, the water inlet valve 303 may also adopt a one-inlet-three-outlet structure, that is, one water inlet and three water outlets, namely, a first water outlet, a second water outlet, and a third water outlet. The first water path is connected to the first water outlet, the main detergent chamber is connected to the second water outlet through one of the second water paths, and the auxiliary detergent chamber is connected to the third water outlet through another second water path.

[0107] Of course, the number of water outlets of the water inlet valve 303 can also be adjusted according to the number of detergent chambers 200C.
