Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a detergent dispensing device and clothing processing equipment. Background Technology

[0002] A washing machine generally includes a casing containing a washing tub. The casing also features a detergent dispensing device that supplies detergent to the washing tub, enabling automatic washing of clothes. The detergent dispensing device typically includes a water tank, which consists of a tank body and a lid. The tank body and lid form a front-opening water tank cavity. The detergent dispenser is located within this cavity and holds detergent, fabric softener, softener, disinfectant, etc. A water inlet cavity is formed on the lid for filling the tank body and water tank cavity with water. Under the impact of the water flow, the detergent (including detergent, fabric softener, softener, and disinfectant) in the dispenser flows through a water hole at the rear of the tank body into the water tank cavity, and then is injected into the washing tub along with the water flow within the cavity.

[0003] In existing technology, the detergent dispenser has a water outlet at the rear end, and a siphon cap is installed at the water outlet to use siphon effect to guide the detergent in the detergent dispenser into the water tank cavity at the bottom. When adding low-viscosity detergent to the detergent dispenser, there is a risk of premature siphoning when it is quickly pushed into the water tank cavity, and the detergent is also prone to overflowing into the water tank cavity due to liquid agitation when pushed in quickly.

[0066] This embodiment discloses a clothing processing device, such as an automatic washing machine or an automatic shoe washing machine.

[0067] The garment processing equipment includes a housing, a washing tub inside the housing, and a detergent dispensing device on the housing for dispensing detergent into the washing tub.

[0068] The structure of the detergent dispensing device is referenced. Figures 1 to 3 It includes a water box 400 and a detergent box 100.

[0069] Structural reference for water box 400 Figure 6 It includes a water box body 410 and a water box cover 420, with the water box cover 420 located on top of the water box body 410, and the two together forming a water box cavity with an open front side.

[0070] The detergent dispenser 100 is pulled out and located inside the water tank cavity. The detergent dispenser 100 is used to hold detergent. Here, detergent refers to washing liquids with cleaning function, such as detergent, softener, fabric softener, disinfectant, etc.

[0071] A water inlet chamber (not shown) is formed inside the water tank cover 420, and the water inlet chamber is connected to an external water inlet pipe. A drain hole 421 and a water inlet hole (not shown) are provided on the bottom wall of the water tank cover 420. The water path in the water inlet chamber is divided into two paths: one path flows into the detergent box 100 through the water inlet hole, and the other path flows directly into the water tank cavity through the drain hole 421.

[0072] Reference Figure 2 and Figure 3 The detergent dispenser 100 has an automatic dispensing chamber 150 and a manual dispensing chamber 160. In this case, the automatic dispensing chamber 150 is located between the two manual dispensing chambers 160.

[0073] When using the manual detergent dispensing function, add an appropriate amount of detergent to the manual dispensing chamber 160, and then fill the water chamber with water. The detergent flows out of the manual dispensing chamber 160 under the influence of the water flow and then flows into the washing tub.

[0074] When using the automatic detergent dispensing function, a certain amount of detergent is pre-filled into the automatic dispensing chamber 150. The automatic dispensing component 300 draws the detergent from the automatic dispensing chamber 150 into the water injection chamber. The water injection chamber is equipped with a dedicated channel for the detergent to flow. The water injection chamber is also equipped with a mixing zone. The detergent and a portion of the water flow in the water injection chamber are fully mixed in the mixing zone, and then flow into the manual dispensing chamber 160 through the water dispensing hole, and then flow into the washing tub.

[0075] The detergent in the manual dispensing chamber 160 flows out through a siphon effect, specifically as follows: Figure 3 and Figure 9 A siphon outlet 171 is located at the rear of the manual dispensing chamber 160. A siphon cap 500 is installed at the siphon outlet 171. The siphon outlet 171 is a cylindrical structure with a vertically penetrating water inlet. The siphon cap 500 is fitted onto the outer periphery of the cylindrical structure, forming a siphon gap between the siphon cap 500 and the cylindrical structure to facilitate water flow. The detergent in the manual dispensing chamber 160 is discharged through the siphon outlet 171 under siphon action.

[0076] The following section describes the structural design employed in this application to avoid premature siphoning.

[0077] When the detergent viscosity in the manual dispensing chamber 160 is low, there is a risk of premature siphoning when it is quickly pushed into the water tank chamber. Also, the detergent may overflow the water tank due to liquid agitation when pushed into the water tank chamber quickly.

[0078] To solve this problem, refer to Figure 9 and Figure 10 In this application, a water-blocking rib 600 is provided on the inner bottom of the manual dispensing cavity 160. The water-blocking rib 600 is located between the siphon port 171 and the left and / or right side walls of the manual dispensing cavity 160.

[0079] If the water-blocking rib 600 is not installed, the detergent in the manual dispensing chamber 160 will flow quickly to the siphon port 171 and accumulate there, resulting in excessively high peaks. If the peaks generated by liquid fluctuations and rise exceed the siphon value switch, premature siphoning will occur.

[0080] This application provides a water-blocking rib 600 near the siphon port 171, which effectively prevents the detergent in the manual dispensing chamber 160 from flowing rapidly towards the rear siphon port 171, avoiding excessively high wave peaks and thus effectively preventing premature siphoning. It also effectively prevents the detergent from overflowing due to agitation when rapidly injected into the water box, which helps to increase the amount of detergent dispensed.

[0081] In some embodiments of this application, reference is made to Figure 9 and Figure 10The water-blocking rib 600 is integrally formed with the detergent box 100, which is convenient for processing. The water-blocking rib 600 includes a water-blocking rib part 610 and a water-blocking rib part 620 with an integral structure.

[0082] The first water-retaining rib 610 extends from the left and / or right side walls of the manual dispensing chamber 160 in the detergent dispenser towards the siphon inlet 171. The second water-retaining rib 620 extends from the first water-retaining rib 610 towards the front of the siphon inlet 171.

[0083] By using the water-blocking rib 610, the water flow channels on the left and / or right sides of the siphon 171 are blocked, reducing the gap between the siphon 171 and the left and / or right side walls of the manual dispensing chamber 160, allowing the detergent to flow quickly into the rear of the siphon 171.

[0084] By using the two baffles 620, the water inlet channel in front of the siphon 171 is effectively narrowed, further preventing the detergent from having excessively high peaks at the siphon 171.

[0085] In one specific embodiment, reference is made to Figure 9 and Figure 10 The siphon 171 is provided with water-blocking ribs 600 on both the left and right sides. The detergent in the manual dispensing chamber 160 flows to the siphon 171 through the gap between the two water-blocking ribs 620, so as to achieve the best effect of avoiding premature siphoning.

[0086] In some embodiments of this application, reference is made to Figure 10 A downwardly recessed groove 173 is provided at the rear side of the manual dispensing chamber 160, and a siphon port 171 is located in the groove 173.

[0087] One water-blocking rib 610 extends from the left and / or right side walls of the manual dispensing chamber 160 toward the edge of the groove 173 near the siphon port 171. The second water-blocking rib 620 extends along the circumferential edge of the groove 173 toward the front of the siphon port 171.

[0088] Taking the setting of two water-blocking ribs 600 as an example, the detergent in the manual dispensing chamber 160 enters the groove 173 through the gap between the two water-blocking ribs 620. The groove 173 serves to store the detergent. Since the groove 173 surrounds the siphon port, it can achieve an effective and stable siphon effect and avoid premature siphoning.

[0089] In some embodiments of this application, the inner bottom wall of the manual dispensing chamber 160 in the detergent dispenser is provided with an upwardly extending column portion 172, and a siphon port 171 is provided inside the column portion 172. The structure of the siphon cap 500 is as follows: Figure 8 The siphon cap 500 is fitted on the outside of the column part 172, and the outer peripheral wall of the siphon cap 500 abuts against the water-blocking rib 600.

[0090] The water-blocking rib 600 not only serves to block water but also helps to improve the installation stability of the siphon cap 500.

[0091] In some embodiments of this application, reference is made to Figure 10 The detergent dispenser has a locking part 174 inside the manual dispensing chamber 160, which is located behind the siphon inlet 171; see reference. Figure 8 The siphon cap 500 has a protrusion 510, which is detachably connected to the buckle 174, so as to realize the detachable connection of the siphon cap 500 and facilitate the removal of the siphon cap 500.

[0092] In some embodiments of this application, reference is made to Figure 11 The outer bottom wall of the manual dispensing cavity 160 is provided with an arc-shaped rib 175, which extends along the circumferential edge of the siphon port 171.

[0093] The 175-degree rib helps to increase the amount of water flowing downwards, disrupts the surface tension of the water, and prevents continuous siphoning.

[0094] The greater the height of the rib 175, the more obvious the effect. In some embodiments of this application, the height h of the rib 175 is ≥ 2.5 mm.

[0095] The following describes the structural design of this application to prevent water from splashing from the drain hole.

[0096] As described above, a stream of water flows down into the water tank cavity through the drain hole 421 within the water inlet chamber of the water tank cover 420. Because there is a certain distance between the drain hole 421 and the bottom wall of the water tank cavity, the water flowing onto the bottom wall of the water tank cavity splashes, easily splashing into the detergent dispenser.

[0097] In response to this issue, refer to Figures 4 to 6 In some embodiments of this application, a water distribution section 700 is provided inside the water box body 410. The water distribution section 700 is directly below the drain hole 421 to disperse the water flowing down from the drain hole 421, reduce or avoid water splashing, and thus prevent water from splashing into the detergent box 100.

[0098] In some embodiments of this application, reference continues to be made to... Figure 5 The water distribution section 700 includes a water-blocking section 710 and water-dividing ribs 720. The water-blocking section 710 forms a drainage area with one side open. The bottom of the drainage area is provided with multiple water-dividing ribs 720 arranged at intervals. The top of the water-blocking section 710 extends towards the drainage hole 421. The height of the water-blocking section 710 is higher than the height of the water-dividing ribs 720. The water flowing down from the drainage hole 421 flows through the drainage area and falls onto the multiple water-dividing ribs 720.

[0099] The water-blocking part 710 plays a certain role in blocking and concentrating the water flow from the drain hole 421, so that the water flow flows down along the drain area enclosed by the water-blocking part 710 until it falls on the water-dividing ribs 720. The multiple water-dividing ribs 720 effectively disperse the entire stream of water, and the water flows out from the front opening of the gap between two adjacent water-dividing ribs 720, thereby effectively avoiding water splashing.

[0100] In some embodiments of this application, reference continues to be made to... Figure 5 The water-blocking part 710 includes two spaced-apart water-blocking vertical ribs, part 711, and a second water-blocking vertical rib 712 disposed between the two water-blocking vertical ribs, part 711. The water-blocking part 710 forms a U-shaped structure with an open front side. The water-dividing rib 720 extends from the second water-blocking vertical rib 712 to the open front side of the water-blocking part 710.

[0101] The drain hole 421 is located directly above the drain area enclosed by the water-blocking part 710. The first water-blocking vertical rib 711 and the second water-blocking vertical rib 712 located in three directions effectively block and collect water flow, while the front opening allows for the smooth flow of water after it is dispersed.

[0102] In some embodiments of this application, the front end of the water-dividing rib 720 extends outward from the opening of the water-blocking part 710, so that the water flow after being diverted by the water-dividing rib 720 can be guided to the outside of the opening of the water-blocking part 710 as soon as possible, thereby improving the smoothness of the water flow.

[0103] A flange 721 is provided on the water-dividing rib 720 near the water-blocking vertical rib 711. The flange 721 is located at the front end of the water-dividing rib 720 and extends towards one side of the water-blocking vertical rib 711. Under the guidance of the flange 721, the water flow between the water-blocking vertical rib 711 and the adjacent water-dividing rib 720 flows to the side of the water-blocking vertical rib 711. In this way, part of the water flowing out from between the multiple water-dividing ribs 720 flows directly to the front of the water-dividing rib 720, and another part flows to the side of the water-dividing rib 720. The water flows out in multiple directions, which helps to further improve the smoothness of water flow.

[0104] In some embodiments of this application, reference is made to Figure 6 The bottom wall of the water box cover 420 is provided with a downwardly extending first extension 422. The first extension 422 is a columnar structure. The first extension 422 is provided with a vertically penetrating drain hole 421. The top of the water-blocking part 710 abuts against the first extension 422.

[0105] The water-blocking part 710 not only serves to block and collect water, but also provides some support for the water box cover 420, thereby improving the installation stability of the water box cover 420.

[0106] In some embodiments of this application, reference continues to be made to... Figure 6 The bottom wall of the water box cover 420 is provided with a downwardly extending second extension 423. The second extension 423 forms a U-shaped structure. The second extension 423 surrounds the periphery of the abutment position between the water-blocking part 710 and the first extension 422, and further blocks the water flow at the bottom outlet of the drain hole 421.

[0107] The following describes the structural design of the automatic detergent dispensing system in this application.

[0108] In some embodiments of this application, reference is made to Figure 2 The automatic dispensing chamber 150 is equipped with a cover at its top, which serves to seal the automatic dispensing chamber 150.

A detergent dispensing pipe 330 is provided on the housing, and a third check valve 3301 is provided at the outlet of the detergent dispensing pipe 330.

[0115] In some embodiments of this application, reference is made to Figures 12 to 15 The filter assembly 200 includes a filter body 210 and a cover 240.

[0116] The filter body 210 is detachably mounted on the bottom surface of the automatic dispensing chamber 150 for filtering detergent. The filter body 210 is provided with filter holes 220. The size of the filter holes 220 is set according to actual needs, so that while the detergent passes through, foreign objects are blocked above the filter body 210. This can filter foreign objects in the detergent or in the automatic dispensing chamber 150, effectively preventing foreign objects from clogging the detergent dispensing passage.

[0117] The filter body 210 can be a filter screen, filter membrane, filter tank, etc., with a filter screen being preferred.

[0118] The cover 240 is located above the filter body 210, at least partially covering the automatic dispensing component 300, and is detachably connected to the automatic dispensing component 300.

[0119] The filter body 210 and the cover 240 are integrated into one unit, making the structure more robust.

The corner of the filter body 210 is provided with mounting holes 230 corresponding to the limiting members.

[0123] The multiple limiting and fixing functions of the filter body 210 by the limiting components make the filter body 210 more firmly installed and less prone to deformation; and the filter assembly 200 is easy to disassemble and install, making it convenient to clean and maintain the filter assembly 200 regularly, and can play a good filtering role.

[0124] Continue to refer to Figure 12 and Figure 13 The bottom of the automatic dispensing chamber 150 is provided with a filter chamber 110, which is located below the filter body 210 and is connected to the automatic dispensing component 300. It is used to store the filtered detergent.

[0125] The automatic dispensing assembly 300 includes a valve assembly and a pusher assembly, which are detachably connected.

[0126] The valve assembly is located in the automatic dispensing chamber 150 and is connected to the filter chamber 110. It is used to open and close the dispensing passage for detergent.

[0127] The pusher assembly is located outside the automatic dispensing chamber 150 and is assembled in correspondence with the valve assembly to open the channel for dispensing detergent.

[0128] The valve assembly includes a valve body, which is detachably connected to a cover 240. Preferably, the cover 240 is provided with a bayonet 250 and the valve body is provided with a protruding locking platform. The bayonet 250 and the locking platform are fitted together to achieve a detachable connection.

[0129] An opening is provided on the side wall of the automatic dispensing chamber 150, and the edge of the opening extends into the interior of the automatic dispensing chamber 150 to form a valve body. The interior of the valve body forms a valve cavity that penetrates the inside and outside of the automatic dispensing chamber 150.

[0130] The valve chamber includes:

[0131] The first valve chamber 3101 is located at the end of the valve body away from the side wall of the automatic dispensing chamber 150;

[0132] The second valve chamber 3102 is located at one end of the valve body that is connected to the side wall of the automatic dispensing chamber 150.

[0133] The first blocking part 3103 is disposed between the first valve chamber 3101 and the second valve chamber 3102. The first blocking part 3103 is disposed on the inner side wall of the valve body and protrudes from the inner surface of the valve body.

[0134] The first valve chamber 3101 and the second valve chamber 3102 constitute the liquid inlet channel.

[0135] Preferably, the diameter of the first valve chamber 3101 is smaller than the diameter of the second valve chamber 3102.

[0136] A first check valve 3104 is provided in the first valve chamber 3101. The first check valve 3104 can reciprocate within the first valve chamber 3101 along the extension direction of the chamber.

[0137] The first check valve 3104 includes a first guide rod 3105. A first sealing head 3106 is provided at one end of the first guide rod 3105 facing the second valve chamber 3102. The first sealing head 3106 cooperates with the first blocking part 3103 to block the liquid inlet channel.

[0138] It also includes a first elastic element 3107, which is sleeved on the other end of the first guide rod 3105 and connected to the first sealing head 3106, for providing a force for the first guide rod 3105 to move toward the second valve chamber 3102.

[0139] Reference Figure 12 , Figure 13 ,as well as Figure 16 The valve assembly also includes a valve cover 3108, which is assembled with the first valve chamber 3101 of the valve body. Preferably, the valve body has a mounting post on the top and the valve cover 3108 has a mounting hole on the top, and the mounting post is assembled with the mounting hole. Both sides of the valve cover 3108 have a latch, and both sides of the valve body have a protruding latch, and the latch is assembled with the latch.

[0140] The valve cover 3108 includes a liquid extraction pipe 3109, which connects the filter chamber 110 and the liquid inlet channel.

[0141] The valve cover 3108 has a first guide cavity 3110 inside, and the first guide rod 3105 can reciprocate within the first guide cavity 3110.

[0142] The liquid extraction pipe 3109 is divided into two interconnected parts, one part is arranged longitudinally and the other part is arranged laterally. The longitudinal part of the liquid extraction pipe 3109 is connected to the filter chamber 110, and the transverse part of the liquid extraction pipe 3109 and the first guide chamber 3110 form a double ring structure. The transverse part of the liquid extraction pipe 3109 is the outer ring and the first guide chamber 3110 is the inner ring. The annular channel between the double ring structures is connected to the longitudinal part of the liquid extraction pipe 3109 and the filter chamber 110 for the flow of detergent.

[0143] It also includes an extraction device, preferably a pump, for extracting detergent from the filter chamber 110 into the extraction pipe 3109.

[0144] Continue to refer to Figure 12 and Figure 13 The pusher assembly includes a housing, a push rod 3201, and a liquid inlet chamber 3202.

[0145] The housing has an opening at one end facing the automatic dispensing chamber 150, and the housing is closed at the other end away from the automatic dispensing chamber 150. The housing can be inserted into the second valve chamber 3102 and is detachably connected to the valve body. The housing forms a cavity inside.

[0146] Preferably, the diameter of the housing cavity is smaller than the diameter of the second valve cavity 3102, so that the housing can be inserted into the second valve cavity 3102. The inner surface of the housing and the outer surface of the valve cavity are provided with corresponding assembly components, so that they can be detachably connected.

[0147] The push rod 3201 is located inside the housing cavity at one end facing the automatic dispensing cavity 150. The push rod 3201 extends outward and protrudes from the opening of the housing to provide force for the first guide rod 3105 to move into the first guide cavity 3110.

[0148] The liquid inlet chamber 3202 is located at one end of the shell cavity away from the automatic dispensing chamber 150. The liquid inlet chamber 3202 is provided with a second blocking part 3208 at one end near the push rod 3201. The second blocking part 3208 is located on the inner side wall of the shell and protrudes from the inner surface of the shell.

[0149] A second check valve 3203 is provided in the liquid inlet chamber 3202. The second check valve 3203 can reciprocate in the liquid inlet chamber 3202 along the extension direction of the chamber. The second check valve 3203 includes a second guide rod 3204. A second sealing head 3205 is provided at one end of the second guide rod 3204 facing the push rod 3201. The second sealing head 3205 cooperates with the second blocking part 3208 to seal the liquid inlet chamber 3202.

[0150] It also includes a second elastic element 3206, which is sleeved on the other end of the second guide rod 3204 and connected to the second sealing head 3205, for providing a force for the second guide rod 3204 to move toward the push rod 3201.

[0151] Preferably, the first elastic element 3107 and the second elastic element 3206 are springs.

[0152] It also includes a valve seat, which has a double-ring structure, including an outer ring and an inner ring that are connected to each other. The outer ring is connected to the inner wall of the liquid inlet chamber 3202, and detergent can flow between the outer ring and the inner ring. The second guide rod 3204 passes through the inner ring and can move back and forth in the inner ring.

[0153] A second guide cavity 3207 is provided at one end of the housing cavity away from the automatic dispensing cavity 150. The second guide cavity 3207 is located downstream of the valve seat. The second guide rod 3204 passes through the inner ring of the valve seat and can reciprocate within the second guide cavity 3207.

[0154] Based on the first check valve 3104, at least one second check valve 3203 is added to the liquid inlet chamber 3202, forming a multi-layer waterproof structure. Even if one check valve leaks, other check valves will still function, which can effectively prevent residual water or liquid in the automatic dispensing chamber 150 from entering the detergent dispensing pipeline 330, causing waste or blockage. At the same time, it can also prevent backflow of detergent or water, ensuring that the automatic detergent dispensing can proceed normally.

[0155] It also includes a drive device connected to the liquid inlet chamber 3202, used to drive the second guide rod 3204 to move into the second guide chamber 3207.

[0156] The preferred driving device is an air extraction device. The air extraction device creates negative pressure in the liquid inlet chamber 3202, driving the second check valve 3203 to move. This causes the second guide rod 3204 to move into the second guide cavity 3207. Simultaneously, the second elastic element 3206 is compressed, causing the second sealing head 3205 to move away from the second blocking part 3208, opening the liquid inlet chamber 3202. The liquid inlet chamber 3202 then connects with the liquid inlet channel, allowing detergent to enter the liquid inlet chamber 3202. When the air extraction device stops extracting air, the second elastic element 3206, under the action of restoring force, pushes the second check valve 3203 to move in the opposite direction, causing the second guide rod 3204 to move away from the second guide cavity 3207. At the same time, the second sealing head 3205 cooperates with the second blocking part 3208 to seal the liquid inlet chamber 3202.

[0157] In addition, the liquid inlet volume can also be controlled by controlling the working state of the air extraction device. For example, by controlling the air extraction device to generate different negative pressures, the moving distance of the second check valve 3203 can be adjusted, and the distance between the second sealing head 3205 and the second blocking part 3208 can be changed, thereby controlling the liquid inlet volume; or, the liquid inlet volume can also be controlled by controlling the air extraction time of the air extraction device.

[0158] The housing is provided with a detergent dispensing pipe 330, which is connected to the liquid inlet chamber 3202 for dispensing detergent.

[0159] Preferably, a third check valve 3301 is provided at the outlet of the detergent dispensing pipe 330, which has a similar function to the second check valve 3203.

[0160] Specifically:

[0161] In the initial state, the detergent box 100 is pulled out, the first sealing head 3106 abuts against the first blocking part 3103 to block the liquid inlet channel, and the second sealing head 3205 abuts against the second blocking part 3208 to block the liquid inlet chamber 3202. At this time, both the extraction device and the air extraction device stop working.

[0162] In operation, detergent is poured into the automatic dispensing chamber 150 and the detergent dispenser 100 is pushed in. After being filtered by the filter body 210, the detergent is stored in the filter chamber 110. During the process of pushing the detergent dispenser 100 in, the push rod 3201 abuts against the first sealing head 3106, providing force for the first guide rod 3105 to move into the first guide chamber 3110. At the same time, the first elastic element 3107 is compressed, causing the first sealing head 3106 to separate from the first blocking part 3103, opening the liquid inlet channel. At this time, the extraction device starts working, opening the filter chamber 110. The detergent in the container is drawn into the liquid extraction pipe 3109 and flows into the liquid inlet channel. At this time, the air extraction device starts to work, creating a negative pressure in the liquid inlet chamber 3202, which drives the second guide rod 3204 to move into the second guide chamber 3207. At the same time, the second elastic element 3206 is compressed, causing the second sealing head 3205 to separate from the second blocking part 3208, opening the liquid inlet chamber 3202. The liquid inlet chamber 3202 is connected to the liquid inlet channel, allowing the detergent to enter the liquid inlet chamber 3202 and then into the detergent dispensing pipe 330 for automatic detergent dispensing.

[0163] When the working state is terminated, the suction device stops suctioning. Under the action of the restoring force, the second elastic element 3206 drives the second guide rod 3204 to move away from the second guide cavity 3207. At the same time, the second sealing head 3205 cooperates with the second blocking part 3208 to block the liquid inlet cavity 3202. The extraction device also stops working. When the detergent box 100 is pulled out, the first sealing head 3106 disengages from the push rod 3201. Under the action of the restoring force, the first elastic element 3107 drives the first guide rod 3105 to move away from the first guide cavity 3110. At the same time, the first sealing head 3106 cooperates with the first blocking part 3103 to block the liquid inlet channel.

[0164] In some embodiments of this application, the top of the outer shell of the push needle assembly is provided with a detergent dispensing pipe 330. One end of the detergent dispensing pipe 330 is connected to the water injection cavity in the water box cover 420, and the other end is connected to the liquid inlet cavity 3202 in the push needle assembly, for dispensing detergent.

[0165] Reference Figure 7 The bottom of the outer shell of the pusher assembly has a mounting hole (not shown), and the bottom wall of the water box 410 has a mounting post 411. The mounting post 411 is inserted into the mounting hole to achieve screwless installation of the pusher assembly.
