Description

Technical Field

[0001] The present invention belongs to the field of clothing washing, and specifically relates to an input device and a clothing treatment device.

Background Art

[0002] Clothing treatment devices are frequently used household appliances. An additive input device is installed in the clothing treatment device. The additive input device mainly includes a water case communicating with the water intake pipeline of the clothing treatment device and a liquid storage case accommodated in the water case. The liquid storage case is usually configured in a structural form that can be pulled out from the water case, so that the user can pull out the liquid storage case from the water case and add additives such as liquid detergent, and / or fabric softener, and / or disinfectant into the case. When the clothing treatment device starts to take water, the additive in the liquid storage case is sucked by the liquid suction device and put into the waterway of the water case. The water in the water intake pipeline first enters the water supply waterway of the water case and is mixed with the additive to form a mixed liquid. Then, it is put into the interior of the clothing treatment device to perform direct component injection cleaning ( "essence cleaning") on the clothing.

[0003] However, in the prior art, usually, a fluid communication assembly is installed on the rear side of the dispenser case, and the push pin of the fluid communication assembly is inserted into a sleeve installed at the bottom of the liquid storage chamber of the dispenser case, so that the additive in the liquid storage chamber is sucked. Also, in order to prevent the additive from flowing out through the sleeve, it is necessary to further install an elastic support in the sleeve for automatically cutting off the sleeve when the push pin is pushed out. With such a configuration, the structure inside the input device becomes complicated, the number of assemblies increases, the production and manufacturing efficiency decreases, and it is easy to cause problems such as getting stuck between piping components. As a result, the dispenser case cannot be normally pushed into the water case.

[0004] In view of the above, the present invention is proposed.

[0005] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and provide an input device and a clothing processing device. In this invention, a rotatable suction pipe is installed in the mounting chamber of the water case, and as the pipe rotates, the distributor case is moved out of the way during the process of removing or pushing in the distributor case, and when the distributor case is located inside the water case, the pipe extends into the liquid storage chamber to suck up the additive. In this way, by replacing the form of the fluid communication assembly, the problems of the assembly inside the water case being complex and the fluid communication assembly being prone to getting stuck are solved.

[0006] To solve the above technical problems, the basic concept of the technical idea adopted by the present invention is as follows.

The suction pipe is installed on the water case via a rotating mounting structure. When the distributor case is removed from the water case, the suction pipe is driven by the distributor case to rotate to a first position, and the piping of the suction pipe is closed.

Specifically, by installing a deformable suction tube in the mounting chamber of the water case, after the distributor case is pushed in, the suction tube is directly inserted into the storage chamber from the top of the distributor case to draw in the additive. In this way, a simple hose replaces the fluid communication assembly, solving the problem of the complex assembly inside the water case and the fluid communication assembly being prone to getting stuck.

[0032] The technical problem that this invention aims to solve is to overcome the shortcomings of the prior art and provide a water injection device. This invention solves the problem in the prior art where the injection pipe is not fixed, is unstable, and oscillates when water is injected, by installing a fixed part on the injection pipe and attaching the fixed part to the water case.

[0033] To solve the above technical problems, the basic concept of the technical idea adopted by the present invention is as follows: The injection device comprises an injection pipe having one end communicating with an injection water channel and the other end having an injection nozzle installed on it, and further comprises a water case having an injection water channel for water intake, and a fixed part is installed on the pipe wall of the injection pipe, and the fixed part is connected to the water case.

It should be noted that these drawings and textual descriptions are not intended to limit the scope of the concept of the present invention in any way, but rather to explain the concept of the present invention to those skilled in the art by referring to a specific embodiment. [Modes for carrying out the invention]

[0047] To further clarify the purpose, technical concept, and advantages of the embodiments of the present invention, the technical concept of the embodiments will be clearly and completely described below with reference to the drawings of the embodiments. The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0048] In describing the present invention, the directions or positional relationships indicated by terms such as "up," "down," "front," "back," "left," "right," "vertical," "inside," and "outside" are based on the directions or positional relationships shown in the drawings and are merely for the purpose of facilitating the description and simplification of the description. They do not indicate or imply that the shown devices or components necessarily have a specific direction or are configured and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0049] In describing this invention, unless otherwise explicitly defined or limited, the terms "attach," "connect," and "connect" should be understood in a broad sense. For example, a connection may be fixed, detachable, or integral. Furthermore, a connection may be mechanical or electrical. Also, a connection may be direct or indirect, mediated through an intermediate intermediary. Those skilled in the art will be able to understand the specific meaning of these terms in this invention depending on the specific circumstances.

[0050] In embodiments of the present invention, the additive is a common consumable used for washing clothes, such as a detergent, rinse agent, fabric softener, and / or disinfectant.

[0051] As shown in Figures 1 to 16, an embodiment of the present invention introduces an input device for clothing processing equipment. The input device comprises a water case 1 provided with an input water channel 3 for drawing in water, and a distributor case 2 that is retractably mounted outward in a mounting chamber 101 inside the water case 1. A liquid storage chamber 210 for storing additives is provided on the distributor case 2. A suction pipe 4 is provided inside the mounting chamber 101 of the water case 1. The suction pipe 4 is a hose, and both ends of the suction pipe 4 are in communication with the input water channel 3 and the liquid storage chamber 210, respectively, and are used to draw the additive into the input water channel 3 and mix it with the water flowing through the input water channel 3 to form a mixed liquid.

[0052] With the above configuration, a deformable suction tube 4 is installed in the mounting chamber 101 of the water case 1. After the distributor case 2 is pushed in, the suction tube 4 is inserted directly into the storage chamber 210 from the upper position of the distributor case 2 to draw in the additive. In this way, a simple hose replaces the fluid communication assembly, solving the problem of the assembly inside the water case 1 being complex and prone to getting stuck.

[0053] In an embodiment of the present invention, a through-hole is drilled in the side wall of the distributor case 2, and the suction tube 4 is inserted into the liquid storage chamber 210 through the through-hole. The through-hole is drilled above the highest liquid level of the additive in the liquid storage chamber 210.

[0054] In a preferred embodiment of the present invention, the top of the distributor case 2 is installed open, and the suction pipe 4 extends from the top of the mounting chamber 101 through an opening into the liquid storage chamber 210. The distributor case 2 is usually installed with an open top, and when the user removes the distributor case 2, they replenish the additive into the liquid storage chamber 210 through this opening. By utilizing this opening, there is no need to add extra openings, further simplifying the internal structure of the dispensing device. In addition, if the user accidentally replenishes too much additive, it is possible to prevent the additive from flowing out of the distributor case 2 through through holes on the side walls of the distributor case 2.

[0055] In this embodiment of the present invention, a connecting joint 321 extending downward is installed at the top of the mounting chamber 101. The upper end of the connecting joint 321 communicates with the water inlet channel 3, and the lower end is detachably connected to the suction pipe 4. As a result, the suction pipe 4 communicates with the water inlet channel 3, which is located outside the mounting chamber 101. More importantly, the suction pipe 4 can be easily replaced. The suction pipe 4 is a hose, and commonly used materials include rubber and silicone. After a certain period of use, the suction pipe 4 deteriorates and hardens due to factors such as oxidation and corrosion by acids and alkalis, which can eventually lead to the pipe rupturing. By detachably installing the suction pipe 4 inside the mounting chamber 101, the user can easily replace the suction pipe 4.

[0056] In this embodiment of the present invention, the inner diameter of the lower end of the connecting joint 321 is greater than or equal to the outer diameter of the liquid outlet end of the suction tube 4, and the suction tube 4 is inserted into the inside of the connecting joint 321.

[0057] In a preferred embodiment of the present invention, the lower end of the communication joint 321 is inserted into the liquid outlet end of the suction pipe 4, and the outer circumference of the communication joint 321 is installed in close contact with the inner circumference of the suction pipe 4.

[0058] In the two embodiments described above, the suction tube 4 is connected to the suction tube 4 by a fitted configuration, ensuring airtightness of the connection and facilitating the installation and removal of the suction tube 4. Relatively speaking, in the preferred embodiment, the liquid outlet end of the suction tube 4 is extended and fitted to the connecting joint 321. Compared to other configurations in which the liquid outlet end is compressed, in this configuration, the pipe wall at the liquid outlet end of the suction tube does not wrinkle due to compression, preventing the additive from passing through the gap created between the wrinkle and the connecting joint 321, and ensuring airtightness of the connection.

[0059] In an embodiment of the present invention, a compression fit structure 322 extending radially outward is provided on the outer circumference of the lower end of the communication joint 321, and the inner diameter of the liquid outlet end of the suction tube 4 is smaller than the outer diameter of the compression fit structure 322. Due to the characteristic that the suction tube 4 is a hose, the compression fit structure 322 further improves the stability of the connection.

[0060] In an embodiment of the present invention, the interlocking structure 322 has an arc-shaped surface. This ensures the stability of the connection and, at the same time, prevents the interlocking structure 322 from damaging the wall of the suction tube 4 due to the arc-shaped surface.

[0061] In an embodiment of the present invention, a positioning groove 111 opening downwards on the outer circumference of the connecting joint 321 is installed in the upper part of the mounting chamber 101. The liquid outlet end of the suction tube 4 is inserted into the positioning groove 111, and the groove wall of the positioning groove 111 is in close contact with the outer circumference wall of the suction tube 4. By installing the positioning groove 111, the length to which the connecting joint 321 is inserted into the suction tube 4 is increased without increasing the vertical height of the mounting chamber 101, further improving the stability of the fit. In addition, by the groove wall of the positioning groove 111 supporting the tube wall of the suction tube 4, a portion of the force borne between the liquid outlet end and the connecting joint 321 when the suction tube 4 is bent is reduced, reducing the degree of oscillation between the suction tube 4 and the connecting joint 321, and further improving the stability of the connection.

[0062] In an embodiment of the present invention, the liquid inlet end of the suction tube 4 is inserted into the liquid storage chamber 210, and the opening of the liquid inlet end of the suction tube 4 is directed toward the bottom of the liquid storage chamber 210.

[0063] With the above configuration, compared to the conventional configuration in which a horizontally extended fluid communication assembly is installed inside the liquid storage chamber 210, the suction tube 4 of the present invention can be installed with its opening directly facing the bottom of the liquid storage chamber 210. This allows the suction tube 4 to more completely aspirate the additives in the liquid storage chamber 210, and keeps the amount of residual additives in the liquid storage chamber 210 to a lower level.

[0064] In this embodiment of the present invention, the connecting joint 321 is located above the liquid storage chamber 210, thereby allowing the suction pipe 4 to extend vertically downward to the liquid storage chamber 210.

[0065] In embodiments of the present invention, the length of the suction tube 4 is equal to, or slightly less than, the distance from the connecting joint 321 to the bottom of the liquid storage chamber 210 directly below. This allows the liquid inlet end of the suction tube 4 to be in close contact with, or at a shorter distance from, the bottom of the liquid storage chamber 210. As a result, the suction tube 4 is made to more completely aspirate the additive in the liquid storage chamber 210, reducing residue.

[0066] In an embodiment of the present invention, a liquid suction hole 401 is provided on the tube wall at the liquid inlet end of the liquid suction tube 4, and both ends of the liquid suction hole 401 communicate with the inside and outside of the liquid suction tube 4, respectively. This increases the passage area at the liquid inlet end of the liquid suction tube 4, thereby improving the suction efficiency of the additive.

[0067] In an embodiment of the present invention, the liquid absorption hole 401 is positioned at a certain distance from the end face of the liquid absorption end of the liquid absorption tube 4.

[0068] In a preferred embodiment of the present invention, a grooved body with an inward recess is provided on the end face of the tube wall of the suction tube 4, forming a suction hole 401. When the liquid level of the additive in the liquid storage chamber 210 falls below the suction hole 401, air in the liquid storage chamber 210 enters the suction tube 4 through the suction hole 401, reducing the vacuum level inside the suction tube 4 and decreasing the liquid discharge efficiency. By positioning the suction hole 401 at the liquid inlet end of the suction tube 4, the above situation occurs only just before the additive in the liquid storage chamber 210 is completely aspirated, thereby improving the suction efficiency of the additive in the suction tube 4 without significantly increasing the amount of additive remaining in the liquid storage chamber 210.

[0069] In an embodiment of the present invention, a cleaning liquid pump is installed between the communication joint 321 and the input pipeline, and the cleaning liquid pump draws air into the suction pipe 4 until it becomes negative pressure, thereby drawing in the additive.

[0070] In a preferred embodiment of the present invention, a Venturi tube 310 is installed on the input water channel 3, and the suction tube 4 communicates with the throat tube 311 of the Venturi tube 310. Due to the characteristics of the Venturi tube 310, the negative pressure generated at the throat tube 311 is used to draw in the additive, thereby creating a negative pressure in the suction tube 4 and drawing in the additive without the need to install a power device such as a pump.

[0071] In an embodiment of the present invention, a buffer chamber 323 is provided on the water case 1, and the buffer chamber 323 communicates with the suction tube 4 and the throat tube 311. By providing the buffer chamber 323, the additive first remains in the buffer chamber 323 before entering the throat tube 311 from the suction tube 4, and is then drawn into the Venturi tube 310. By adjusting the flow rate of the additive through the buffering action, the additive flows into the Venturi tube 310 at a constant speed, and fluctuations in the additive concentration in the mixed liquid are kept to a minimum.

[0072] In this embodiment of the present invention, the bottom of the buffer chamber 323 is connected to the liquid outlet end of the suction tube 4, and one side wall communicates with the throat tube 311. The buffer chamber 323 enables the bending of the water channel, which reduces the space occupied by the water channel within the input device. Furthermore, after the additive enters the buffer chamber 323 from the suction tube 4, there is a process in which the buffer chamber 323 is gradually filled, and during this process, the flow rate of the additive flowing from the buffer chamber 323 into the venturi tube 310 also gradually increases. This prevents the additive with a high flow rate from directly entering the throat tube 311 and hitting the inner wall of the throat tube 311, thereby reducing the structural strength of the throat tube 311 and the service life of the venturi tube 310.

[0073] In this embodiment of the present invention, the horizontal cross-sectional area of ​​the buffer chamber 323 is larger than the passage area of ​​the suction tube 4. This reduces the flow velocity of the additive in the suction tube 4 as it enters the buffer chamber 323, thereby further improving the buffering effect.

[0074] In an embodiment of the present invention, a communication structure 320 is installed on the water case 1, and is located at the top of the water case 1. The internal cavity of the communication structure 320 constitutes a buffer chamber 323.

[0075] In an embodiment of the present invention, a communication joint 321 is connected to the bottom of the communication structure 320, which communicates with the buffer chamber 323. The communication joint 321 extends from the top of the water case 1 to the internal mounting chamber 101 and is connected to the suction pipe 4 inside the mounting chamber 101.

[0076] In an embodiment of the present invention, a communication port 112 is provided at the top of the water case 1, which communicates with the buffer chamber 323. The bottom of the communication structure 320 is locked and installed above the communication port 112, and the communication joint 321 of the communication structure 320 is inserted into the mounting chamber 101 through the communication port 112.

[0077] In an embodiment of the present invention, the diameter of the communication port 112 is larger than the outer diameter of the communication joint 321. The peripheral wall of the communication port 112 and the bottom of the communication structure 320 are provided to surround each other and form a positioning groove 111, and the outer circumference of the liquid outlet end of the suction tube 4 is inserted into the positioning groove 111 in correspondence. Preferably, the diameter of the communication port 112 is equal to the outer diameter of the liquid outlet end of the suction tube 4.

[0078] In an embodiment of the present invention, an annular first sealing rib 113 projecting upward is provided on the upper surface of the water case 1. The annular first sealing rib 113 surrounds the outer circumference of the communication structure 320, and the annular first sealing rib 113 is in contact with the communication structure 320 in a sealed state.

[0079] In an embodiment of the present invention, two second sealing ribs 324 are arranged vertically along the outer bottom of the communication structure 320, and each second sealing rib 324 is provided within the inner ring of the first sealing ring. A sealing ring is fitted onto the outer wall of the communication structure 320 located between the two second sealing ribs 324, with the inner circumference of the sealing ring in close contact with the outer wall of the communication structure 320, and the outer circumference of the sealing ring in tight sealing contact with the inner surface of the first sealing rib 113. The two second sealing ribs 324 form a groove that fixes the sealing ring, and further, the sealing ring and the first sealing rib 113 come into contact with each other, thereby achieving a sealed state of contact between the outer wall of the communication structure 320 and the first sealing rib 113.

[0080] In an embodiment of the present invention, the upper inner circumference of the first sealing rib 113 is installed so as to be inclined from bottom to top toward the outer circumference, forming a bell mouth, thereby allowing the communication structure 320 to be easily installed inside the first sealing rib 113.

[0081] In an embodiment of the present invention, the venturi tube 310 is mounted horizontally on the upper part of the water case 1, and the buffer chamber 323 communicates with the throat tube 311 of the venturi tube 310 via a horizontally extending conduit.

[0082] As shown in Figures 1 to 16, an embodiment of the present invention further describes the input device. The input device comprises a water case 1 provided with an input channel 3 for guiding the intake water, a distributor case 2 retractably installed inside the water case 1 and provided with a liquid storage chamber 210 for storing additives, and a suction pipe 4 whose ends are connected to the input channel 3 and the liquid storage chamber 210, respectively, for drawing the additive into the input channel 3 and mixing it with the intake water flowing through the input channel 3 to form a mixed liquid. The suction pipe 4 is installed on the water case 1 via a rotating mounting structure 5. When the distributor case 2 is removed from the water case 1, the suction pipe 4 is driven by the distributor case 2 to rotate to a first position, blocking the conduit of the suction pipe 4. When the distributor case 2 is pushed into the water case 1, the suction pipe 4 is driven by the distributor case 2 to rotate to a second position, opening the conduit of the suction pipe 4.

[0083] With the above configuration, the fluid communication assembly is replaced by rotating the suction tube 4 to move aside the distributor case 2 while the distributor case 2 is moving, solving problems such as the complexity of the assembly inside the water case 1 and the fluid communication assembly being prone to getting stuck.

[0084] In embodiments of the present invention, the suction tube 4 may be installed as a rigid tube that is not deformable in its entirety, or as a hose that is partially deformable, or as a hose that is entirely deformable.

[0085] In an embodiment of the present invention, the suction tube 4 is a non-deformable suction tube 4, and the liquid outlet end of the suction tube 4 is connected to the input water channel 3 in a way that allows it to be opened and closed. When the suction tube 4 is rotated to the first position, the entire suction tube 4 rotates, and the liquid inlet end and liquid outlet end are disconnected from the liquid storage chamber 210 and the input water channel 3, respectively.

[0086] In another embodiment of the present invention, the suction tube 4 is installed as either a partially deformable hose or as an entirely deformable hose. When the suction tube 4 rotates to a first position, the middle of the suction tube 4 is bent. As a result, the liquid inlet end rotates and is disconnected from the liquid storage chamber 210, while the liquid outlet end of the suction tube 4 maintains communication with the water inlet channel 3. Alternatively, the inside of the suction tube 4 is disconnected at the bent position, thereby blocking the liquid inlet end from the water inlet channel 3.

[0087] In an embodiment of the present invention, the rotating mounting structure 5 includes a drive piece 510 that is rotatably mounted on the water case 1 around an axis. The drive piece has a coaxial rotating shaft 520 on one side, and the rotating shaft 520 is connected to the suction tube 4. The drive piece 510 is equipped with a trigger portion 511 that extends outward from the axis. The distributor case 2 is in contact with the trigger portion 511, and when the distributor case 2 is removed or pushed in, the distributor case 2 drives the drive piece 510 to rotate around the axis. By installing the drive piece 510, the length of linear movement of the distributor case 2 is converted into an angular change of rotation around the axis, thereby realizing the technical idea that the removal and pushing operations driven by the distributor case 2 drive and rotate the suction tube 4.

[0088] In this embodiment of the present invention, the distributor case 2 is pushed into the water case 1 through the front opening. The rotating mounting structure 5 further comprises a drive unit 220 installed on the distributor case 2, the rear of which contacts the trigger portion 511 of the drive piece 510. By making the direction of movement of the distributor case 2 the same as the direction of rotation of the liquid inlet end of the suction tube 4, when the distributor case 2 is removed, the suction tube 4 rotates forward and at the same time the front of the liquid storage chamber 210 also moves forward, preventing the suction tube 4 from colliding with the front chamber wall of the liquid storage chamber 210 and protecting the liquid inlet end of the suction tube 4.

[0089] In an embodiment of the present invention, the drive unit 220 is a columnar structure that extends upward.

[0090] In an embodiment of the present invention, the drive unit 220 is a columnar structure having an arc-shaped surface, and the upper part of the arc-shaped surface of the drive unit 220 abuts against the trigger unit 511.

[0091] In this embodiment of the present invention, the drive unit 220 has a semi-cylindrical structure. The drive unit 220 is installed on the left or right side of the distributor case 2, with the arcuate surface of the drive unit 220 facing inward towards the distributor case 2 and the opposite plane facing outward towards the distributor case 2. This reduces the space occupied by the drive unit 220 on the distributor case 2.

[0092] In an embodiment of the present invention, the rotating mounting structure 5 further comprises an elastic component 530. One end of the elastic component 530 abuts against the water case 1, and the other end abuts against the rear side of the trigger portion 511. If the distributor case 2 is removed without the elastic component 530 installed, the drive piece 510 drives the suction tube 4 to rotate to the first position solely by its own weight, and because the drive piece 510 and the suction tube 4 form a lever model, the forces acting on both ends may balance before reaching the first position. The present invention provides a driving force for the rotation of the suction tube 4 by installing the elastic component 530. This ensures that the suction tube 4 can be rotated stably to the first position, and thus ensures stable operation of the dispensing device.

[0093] In this embodiment of the present invention, the elastic component 530 is a torsion spring. A drive rod is mounted coaxially with the rotating shaft 520 on one side of the drive piece 510, and the torsion spring is fitted onto the drive rod. One end of the torsion spring abuts against the water case 1, and the other end abuts against the rear side of the trigger portion 511. Compared to the configurations of tension springs or compression springs, the deformation form of the torsion spring is more suitable for the rotational structure and provides a restoring force.

[0094] In an embodiment of the present invention, a drive projection 540 is provided on the side of the trigger portion 511 where the torsion spring is installed. A recessed linear groove is provided on the rear side of the drive projection 540, and the other end of the torsion spring is positioned to abut against the bottom of the linear groove. The provision of the linear groove provides more stable fixing of the torsion spring and prevents the torsion spring from coming off, which would prevent the rotation mounting structure 5 from being used properly.

[0095] In embodiments of the present invention, the drive projection 540 may be a hollow sleeve structure, and the sleeve structure is coaxially fitted to the outside of the rotating shaft 520.

[0096] In a preferred embodiment of the present invention, one side of the drive piece 510 is connected to the rotating shaft 520, and the other side is connected to the drive projection 540. The drive projection 540 is a columnar structure installed coaxially with the rotating shaft 520.

[0097] In an embodiment of the present invention, a recessed support groove 115 is provided on the water case 1, and the support groove 115 is perpendicular to the axis of the drive piece 510. One end of the torsion spring is installed in the support groove 115.

[0098] In an embodiment of the present invention, the water case 1 is equipped with a mounting chamber 101, and the distributor case 2 is installed in the mounting chamber 101 so as to be removable.

[0099] In an embodiment of the present invention, a support projection is installed on the chamber wall of the mounting chamber 101, protruding inward, and the support groove 115 is installed on the support projection.

[0100] In this embodiment of the present invention, a sleeve 410 is fitted onto the outer circumference of the suction tube 4, and one side of the sleeve 410 is connected to the rotating shaft 520 of the rotating mounting structure 5. By installing the sleeve 410, the suction tube 4 is installed so that it can be separated from the rotating mounting structure 5. This simplifies the assembly structure and facilitates production and manufacturing.

[0101] In this embodiment of the present invention, a driven shaft 550 is connected to the other side of the sleeve 410. The driven shaft 550 is rotatably mounted on the water case 1 and is mounted coaxially with the rotating shaft 520. Two shafts are coaxially mounted on each side of the suction tube 4, and by simultaneously supporting the suction tube 4, the rotational direction of the suction tube 4 is made more stable, preventing the rotational trajectory of the suction tube 4 from deviating from a preset trajectory.

[0102] In an embodiment of the present invention, a support portion 130 is installed on the water case 1. A support hole 131 is provided on the support portion 130, and the rotating shaft 520 extends from one side to the other of the support portion 130 through the support hole 131. The rotating mounting structure 5 is rotatably installed inside the water case 1 via the support portion 130.

[0103] In this embodiment of the present invention, support parts 130 are provided on both sides of the suction tube 4, and the rotating shaft 520 and driven shaft 550 of the rotating mounting structure 5 are installed in the support holes 131 of the corresponding support parts 130. The rotating mounting structure 5 is rotatably mounted inside the water case 1 via the two support parts 130.

[0104] In this embodiment of the present invention, the support parts 130 are each installed on the upper part of the mounting chamber 101, and the rotating mounting structure 5 is attached to the upper part of the mounting chamber 101 via the support parts 130.

[0105] In an embodiment of the present invention, the water case 1 consists of an upper cover 110 and a lower case body 120. The lower case body 120 is recessed downwards to form a mounting chamber 101, and the distributor case 2 is installed on the lower case body 120. The upper cover 110 is locked and installed on the lower case body 120, and the lower surface of the upper cover 110 forms the upper part of the mounting chamber 101.

[0106] In this embodiment of the present invention, the water inlet channel 3 is installed on the upper cover 110, and the suction pipe 4 is installed extending vertically downward from the lower surface of the upper cover 110.

[0107] In an embodiment of the present invention, the extension direction of the trigger portion 511 of the drive piece 510 is positioned perpendicular to the suction tube 4.

[0108] In an embodiment of the present invention, when the distributor case 2 is removed, the trigger portion 511 of the drive piece 510 is positioned vertically downward, and the liquid inlet end of the suction tube 4 is positioned horizontally forward. When the distributor case 2 is pushed in, the extended end of the trigger portion 511 of the drive piece 510 is driven by the drive unit 220 to rotate backward and be positioned horizontally, and the liquid inlet end of the suction tube 4 rotates downward around its axis to be positioned vertically and located inside the liquid storage chamber 210.

[0109] In this embodiment of the present invention, the lower surface of the upper cover 110 is recessed inward to form a housing groove 114, and the rotating mounting structure 5 and the suction tube 4 are installed within the housing groove 114.

[0110] In this embodiment of the present invention, when the distributor case 2 is removed, the liquid inlet end of the suction tube 4 is housed in the storage groove 114 when the suction tube 4 has rotated to the first position. When the distributor case 2 is pushed in, the liquid inlet end of the suction tube 4 extends out of the storage groove 114 and rotates toward the inside of the liquid storage chamber 210, and when the suction tube 4 is in the second position, the liquid inlet end of the suction tube 4 is installed vertically within the liquid storage chamber 210.

[0111] In this embodiment of the present invention, the support portion 130 is installed within the housing groove 114.

[0112] In this embodiment of the present invention, each support portion 130 extends in the front-rear direction, and both the front and rear ends of the support portion 130 are connected to the groove walls on both the front and rear sides of the housing groove 114, dividing the housing groove 114 into a plurality of chambers arranged in the left-right direction. Each chamber communicates with the others via a support hole 131 on the support portion 130. The rotating mounting structure 5 and the suction tube 4 are installed in different chambers.

[0113] In an embodiment of the present invention, an inwardly recessed notch is provided on the end face of the lower end of the support portion 130. The notch communicates with the support hole 131, and the width of the notch in the front-rear direction is smaller than the diameter of the rotating shaft 520. As a result, the rotating shaft 520 is pushed into the support hole 131 by interference fit with the notch, and the rotating shaft 520 engages with the support hole 131 via the end walls of the support portion 130 on both sides of the notch.

[0114] With the above configuration, in a state where the rotating mounting structure 5 can be stably installed inside the upper cover 110, simply pressing the rotating shaft 520 toward the notch causes the end walls of the support portions 130 on both the front and rear sides of the notch to deform in the front-rear direction, thereby increasing the width of the notch in the front-rear direction. This allows the rotating shaft 520 to enter the support hole 131 through the notch, facilitating the installation of the rotating support structure.

[0115] In an embodiment of the present invention, each support portion 130 is provided with a notch, and the rotating shaft 520 and the driven shaft 550 are each mounted in the support hole 131 via the notch.

[0116] In an embodiment of the present invention, one end of the driven shaft 550 is connected to a sleeve, and the other end is provided with a position-limiting projection 551 that extends radially outward. The diameter of the position-limiting projection 551 is larger than the diameter of the support hole 131 of the adjacent support portion 130.

[0117] In this embodiment of the present invention, the suction tube 4 is a deformable hose. The liquid inlet end of the suction tube 4 is connected to the water inlet channel 3, a sleeve 410 is fitted onto the outer circumference of the suction tube 4, and the rotating mounting structure 5 is connected to one side of the sleeve 410.

[0118] In an embodiment of the present invention, when the distributor case 2 is removed, the distributor case 2 drives the sleeve 410 to rotate upward, the sleeve 410 bends the suction tube 4, the liquid outlet end of the suction tube 4 maintains connection with the input water channel 3, and the liquid inlet end rotates upward to a first position. When the distributor case 2 is pushed in, the distributor case 2 drives the sleeve 410 to rotate downward, the sleeve 410 restores the bent suction tube 4 to a straightened state, and the liquid inlet end rotates downward to a second position.

[0119] In an embodiment of the present invention, the rotating support structure is connected to one end of the sleeve 410 that is closer to the liquid outlet end of the suction tube 4.

[0120] In an embodiment of the present invention, a recessed relief port is provided on the end face of the sleeve 410 that connects to the drive rod, and the relief port is provided on the side wall of the sleeve 410 in the same direction as the direction in which the suction tube 4 is bent. As a result, when the liquid suction end is in the second position, a portion of the tube wall of the suction tube 4 is located within the relief groove 411.

[0121] There is one technical challenge in the manner in which the hose is driven and bent by the sleeve 410. Specifically, when the lower end of the sleeve 410 rotates forward, the upper end of the sleeve 410 rotates backward at the same time. Thus, when the suction tube 4 is positioned in the first position, the extension of the suction tube 4 from the liquid outlet end to the liquid inlet end is first installed at an inclination backward from top to bottom, and then bent forward. With this installation, the bending angle of the suction tube 4 becomes greater than 90 degrees. When bent so sharply, the rate of deterioration of the suction tube 4 is accelerated, and irreversible distortion occurs in the suction tube 4, affecting the suction effect. Furthermore, if the suction tube 4 is bent significantly, in order to satisfy the bending condition, the suction tube 4 moves to the rear side of the horizontally positioned sleeve 410, causing the liquid inlet end of the suction tube 4 to enter the interior of the sleeve 410. As a result, any additives adhering to the outer circumference of the liquid inlet end also adhere to the inner circumference of the sleeve 410, affecting the sanitary condition inside the sleeve 410.

[0122] The present invention, through the above configuration, provides a space to accommodate the bend in the suction tube 4 that has been bent by the relief groove 411. As a result, the suction tube 4, which is located in the first position, is installed vertically downward and bent horizontally forward, so that the degree of bending of the suction tube 4 is reduced, and as a result the above problem is solved.

[0123] In an embodiment of the present invention, a relief hole 412 is provided on the tube wall of the sleeve 410. When the suction tube 4 is bent, the bent portion is compressed on the inside of the suction tube 4. This compressed portion transmits a pressing force to both ends of the suction tube 4, causing a deformation in which a portion of the surrounding tube wall expands outward. This deformation presses against the inner wall of the sleeve 410, potentially causing irreversible strain on the sleeve 410. By providing the relief hole 412, the relief hole 412 provides space to accommodate the deformation of the suction tube 4, preventing the suction tube 4 from excessively pressing against the inner circumferential wall of the sleeve 410, thereby solving the above problem.

[0124] In this embodiment of the present invention, the relief holes 412 are installed on the upper and lower side pipe walls of the horizontally arranged sleeve 410.

[0125] In an embodiment of the present invention, the relief holes 412 are arranged alternately on the upper and lower sides of the horizontally positioned sleeve 410.

[0126] In this embodiment of the present invention, the water inlet channel 3 is installed separately from the water case 1, and the venturi tube 310 is attached to the top of the water case 1.

[0127] In an embodiment of the present invention, a water supply channel 6 is further installed on the water case 1, and the outlet end of the water supply channel 6 extends to the top of the liquid storage chamber 210. By introducing intake water into the liquid storage chamber 210, the liquid storage chamber 210 is flushed out, and any additives remaining in the liquid storage chamber 210 are discharged.

[0128] In this embodiment of the present invention, the water supply channel 6 is integrated into the upper part of the water case 1.

[0129] In an embodiment of the present invention, an upwardly projecting rib plate is installed on the upper part of the water case 1, and the rib plate is arranged to surround and form a water guide channel 601. A cover plate 602 is locked and installed on the upper part of the water guide channel 601, forming a water supply channel 6.

[0130] In an embodiment of the present invention, the cover plate 602 is molten-coated onto the upper part of the water channel 601.

[0131] In an embodiment of the present invention, a plurality of liquid storage chambers 210 are installed inside the distributor case 2, and the same number of water supply channels 6 as the liquid storage chambers 210 are installed on the water case 1 in a one-to-one correspondence.

[0132] In this embodiment of the present invention, the bottom of the distributor case 2 is installed at a distance from the bottom of the mounting chamber 101 of the water case 1. A siphon structure 230 is installed in each liquid storage chamber 210. The siphon structure 230 includes a siphon tube extending upward from the bottom of the liquid storage chamber 210, and the lower end of the siphon tube communicates with the lower part of the distributor case 2. A siphon cap is fitted over the siphon tube, and the siphon cap is an arc-shaped end cap that opens downward. The center of the lower surface of the siphon cap is located above the top of the siphon tube and is installed at a distance from the siphon tube. The height of the outer edge of the siphon cap is lower than the height of the top of the siphon tube, and the outer edge is installed at a distance from the tube wall of the siphon tube. The siphon structure 230 discharges the water taken in from the distributor case 2 to the bottom of the distributor case 2 by the siphon effect, and allows it to flow out from the input device through the opening of the mounting chamber 101.

[0133] In an embodiment of the present invention, the bottom of each liquid storage chamber 210 is installed with a downward slope from the surrounding area down to the siphon structure 230. This allows the additive and the intake water to be guided to the siphon cap, thereby enabling the intake water to be completely discharged.

[0134] In an embodiment of the present invention, the liquid storage chamber 210 comprises an input chamber 211 and a water intake chamber 212, and a one-to-one correspondence between the input chamber 211 and the liquid intake pipe 4 is installed within each input chamber 211.

[0135] In this embodiment of the present invention, the liquid outlet ends of each water supply channel 6 are in communication with the upper part of the mounting chamber 101.

[0136] In an embodiment of the present invention, a first water distribution plate 141 is installed in the mounting chamber 101 above the input chamber 211, and a plurality of water distribution holes are installed on the first water distribution plate 141. Each water distribution hole is positioned directly opposite the bottom of the liquid storage chamber 210, and the orientation of each water distribution hole is offset from the siphon cap of the corresponding liquid storage chamber 210. As a result, the water ejected from each water distribution hole avoids the siphon cap and is sprayed directly onto the bottom of the input chamber 211, thereby targeting and washing the bottom of the input chamber 211 and improving the cleaning effect.

[0137] In the embodiment of the present invention, each suction tube 4 is installed to the left or right of the corresponding siphon cap. Each water distribution hole is installed facing the front and / or rear of the input chamber 211. As a result, the water injected into the input chamber 211 flows from the front and / or rear towards the central siphon cap, improving the rinsing effect.

[0138] In an embodiment of the present invention, a second water distribution plate 142 is installed above the water intake chamber 212 in the mounting chamber 101. The main water distribution port is installed on the water distribution plate above the siphon cap of the water intake chamber 212. Since there is no suction pipe 4 installed inside the water intake chamber 212, during use, the additive inside the water intake chamber 212 is dissolved by the water intake alone and then discharged to the outside of the distributor case 2 via the siphon structure 230. Therefore, by installing the main water distribution port above the siphon cap, the water intake is buffered on the siphon cap, reducing the flow velocity. As a result, the additive inside the water intake chamber 212 is not directly washed away, preventing the additive from being sufficiently dissolved and thus avoiding an impact on the cleaning effect of clothes.

[0139] In an embodiment of the present invention, a secondary water distribution port is further arranged on the second water distribution plate 142. The diameter of the secondary water distribution port is smaller than that of the main water distribution port, and the orientation of the secondary water distribution port is offset from that of the siphon cap. The small water flow out from the secondary water distribution port washes the intake chamber 212, but because the water flow out from the secondary water distribution port is small, the situation in which the additive is directly washed away, as described above, does not occur. This ensures that the additive in the intake chamber 212 is sufficiently dissolved, and at the same time adds a washing function to the intake chamber 212, improving the cleaning effect on the intake chamber 212.

[0140] In this embodiment of the present invention, a downwardly recessed mounting groove 240 is installed inside the distributor case 2. An input case 213 is installed inside the mounting groove 240, and the inside of the input case 213 constitutes an input chamber 211. A drain port 242 is installed on the rear side wall of the mounting groove 240 in the distributor case 2. Each mounting groove 240 has a downwardly recessed drain groove 241 installed below the siphon structure 230 of the input chamber 211, and the drain grooves 241 communicate with each other and the drain port 242. As a result, the water discharged from the siphon structure 230 first flows into the drain groove 241 and is buffered, and then flows out of the distributor case 2 via the rear drain port 242, flows to the bottom of the mounting chamber 101, and is then discharged to the outside of the input device.

[0141] In this embodiment of the present invention, the drainage channel 241 is a rectangular channel body, and the rear mounting channel 240 shares a channel wall.

[0142] In this embodiment of the present invention, arc-shaped chamfers are installed at the corners of both ends of the drain wall on the front side of the drain 241, thereby avoiding the creation of sanitary blind spots.

[0143] In an embodiment of the present invention, the groove walls on both the left and right sides and / or the front groove wall of the drainage groove 241 are installed as groove walls that slope inward from top to bottom, thereby facilitating the discharge of the water by guiding the water intake to the rear of the bottom of the drainage groove 241.

[0144] In this embodiment of the present invention, the drive unit 220 is installed on one side of the groove wall of the mounting groove 240. The input case 213 has a press-formed portion that is recessed inward on the corresponding side, and this press-formed portion is installed in the same shape as the corresponding surface of the drive unit 220. By connecting the drive unit 220 to the groove wall, the connection area between the drive unit 220 and the distributor case 2 is increased, improving the stability of the connection.

[0145] In an embodiment of the present invention, the rotating mounting structure 5 is installed on the left or right side of the upper part of the mounting chamber 101.

[0146] In an embodiment of the present invention, a drain pipe 121 extending upward is installed at the bottom of the mounting chamber 101 of the water case 1. The lower end of the drain pipe 121 communicates with the lower part of the water case 1. If the water taken in from the space between the bottom of the mounting chamber 101 and the bottom of the distributor case 2 is not drained quickly, the drain pipe 121 assists in draining, causing the water level in the mounting chamber 101 to rise higher than the upper part of the outer circumference of the distributor case 2, thus preventing backflow into the liquid storage chamber 210.

[0147] In this embodiment of the present invention, the drain pipe 121 is installed at the rear bottom of the mounting chamber 101.

[0148] As shown in Figures 1 to 17, the embodiment of the present invention further describes the input device. The input device comprises an injection pipe 7, one end of which is in communication with the input water channel 3 and the other end of which is fitted with an injection nozzle 710, and further comprises a water case 1 in which the input water channel 3 for water intake is provided. A fixing part 720 is installed on the pipe wall of the injection pipe 7, and the fixing part 720 is connected to the water case 1.

[0149] With the above installation, the fixing part 720 is installed on the injection pipe 7, and via the fixing part 720 it is attached to the water case 1, thereby achieving stable fixing of the injection pipe 7, avoiding the problem of the injection pipe 7 oscillating when water is injected, improving the stability of the connection between the injection pipe 7 and the input water channel 3, and extending the service life of the injection pipe 7.

[0150] As shown in Figure 17, in one embodiment of the present invention, the fixing portion 720 of the spray structure is a locking piece 851 extending outward from the spray pipe 7, and the spray structure is installed at the bottom of the water case 1. Each locking piece extends toward the left or right edge of the bottom of the water case 1, and a locking claw 852 extending upward is provided at the extended end of the locking piece. Each locking claw 852 abuts against the left or right side wall of the water case 1, and the spray structure is fixed on the water case 1 by the frictional force between the locking claw 852 and the water case 1.

[0151] As shown in Figures 1 to 16, in a preferred embodiment of the present invention, a connecting portion 8 is installed on the water case 1, and the fixing portion 720 is fitted and connected to the connecting portion 8. The fitted connection between the fixing portion 720 and the connecting portion 8 realizes a fixed connection between the water case 1 and the spray pipe 7.

[0152] In this embodiment of the present invention, a first fixing hole 721 is drilled in the fixing portion 720, and a fixing component is installed in each of the first fixing holes 721. The connecting portion 8 is provided with a corresponding connecting hole 810 installed on the water case 1, and the fixing component is fitted and connected to the corresponding connecting hole 810. Each of the first fixing holes 721 is connected to the corresponding connecting hole 810. The spray tube 7 is fixed to the water case 1 via the fixing component, which further facilitates the installation of the spray tube 7.

[0153] In this embodiment of the present invention, the fixing component is detachably connected to the connection hole 810. This allows the spray tube 7 to be removed from the water case 1 by removing the fixing component, facilitating replacement of the spray tube 7 by the user.

[0154] In embodiments of the present invention, the fastening component is a screw or a rivet.

[0155] In an embodiment of the present invention, a second fixing hole 722 is further provided on the fixing portion 720. The connecting portion 8 is equipped with a protruding fixing column 820 installed correspondingly on the water case 1, and each fixing column 820 is inserted into the corresponding second fixing hole 722. By installing the fixing columns 820, the fixing columns 820 are inserted into the second fixing holes 722 before the spray pipe 7 is fixed to the water case 1 via the fixing components, thereby enabling pre-positioning of the spray pipe 7 and facilitating the first fixing hole 721 to face the corresponding connecting hole 810.

[0156] In this embodiment of the present invention, the outer diameter of the projection tip of the fixing column 820 gradually decreases. This makes it easier to further insert the front end of the fixing column 820 into the corresponding second fixing hole 722.

[0157] In an embodiment of the present invention, outwardly projecting first position limiting ribs 841 are installed on the water case 1, and each first position limiting rib 841 is installed on both sides of the injection pipe 7. Each first position limiting rib 841 is installed in close contact with the pipe wall between the fixing portion 720 and the injection nozzle 710 of the injection pipe 7.

[0158] In an embodiment of the present invention, outwardly projecting second position limiting ribs 842 are installed on the water case 1, and each second position limiting rib 842 is installed on both sides of the injection pipe 7. Each second position limiting rib 842 is in contact with the injection pipe 7 and the corresponding fixing portion 720.

[0159] With the above configuration, each position limiting rib is installed in close contact with the injection pipe 7 and / or the fixing part 720, thereby enabling pre-positioning for the installation of the injection pipe 7, while simultaneously limiting and supporting the position on both sides of the injection pipe 7. When the injection pipe 7 receives a reaction force from the injected water, each position limiting rib can bear a portion of the reaction force, reducing the force received by the fixing part 720. By distributing the force, the structural strength of the fixing part 720 is increased, and its service life is improved.

[0160] In embodiments of the present invention, the cross-section of each first position limiting rib 841 is a cross structure, thereby increasing the structural strength of the first position limiting rib 841 itself.

[0161] In embodiments of the present invention, the cross-section of each second position limiting rib 842 is T-shaped. The horizontal plane of the T-shape is installed in close contact with the fixing portion 720, one end of the horizontal T-shape is installed in close contact with the injection pipe 7, and the vertical T-shape supports the horizontal side and increases the structural strength of the horizontal side.

[0162] In this embodiment of the present invention, the injection pipe 7 is installed horizontally in the front-rear direction, and the injection nozzle 710 is installed at the front end of the injection pipe 7.

[0163] In this embodiment of the present invention, the first fixing hole 721 is located in front of the second fixing hole 722.

[0164] In this embodiment of the present invention, each second position limiting rib 842 is installed at a position behind the fixing portion 720. When the spray nozzle 710 sprays water during use, the reaction force from the spraying water is decomposed into a component force moving away from the spray nozzle 710 and a component force moving towards the rear of the spray pipe 7. By installing the second position limiting rib 842 at the rear of the fixing portion 720, the second position limiting rib 842 is made to bear the component force moving towards the rear of the spray pipe 7, thereby reducing the stress on the fixing portion 720 in that direction and further improving the structural strength and service life of the fixing portion 720.

[0165] In this embodiment of the present invention, fixing parts 720 are installed on both sides of the spray tube 7, and each fixing part 720 is a thin plate-like structure installed parallel to the water case 1. Each fixing part 720 is installed with a gap between it and the water case 1, and the water case 1 is provided with outwardly protruding connecting projections 830, each connecting projection 830 making close contact with its corresponding fixing part 720. Each connecting part 8 is installed on its corresponding connecting projection 830. The installation of the connecting projections 830 allows the fixing parts 720 to be stably connected even when they are installed with a gap between them and the water case 1. Furthermore, because a portion of the fixing part 720 is installed without contacting the water case 1, when the spray tube 7 oscillates, the portion that does not come into contact vibrates slightly, which buffers and absorbs the reaction force of water spraying, thereby reducing the vibrations experienced by the water case 1.

[0166] In the embodiment of the present invention, each fixing part 720 is a thin plate-like structure installed parallel to the water case 1.

[0167] In an embodiment of the present invention, the nozzle opening of the injection nozzle 710 is positioned facing away from the water case 1, and a support surface is provided on the opposite side, with the support surface in contact with the water case 1. The provision of the support surface increases the contact area between the injection nozzle 710 and the water case 1, making the contact between the injection nozzle 710 and the water case 1 more stable, reducing the pressure of the injection nozzle 710 on the surface of the water case 1, and preventing distortion of the water case 1.

[0168] In an embodiment of the present invention, the injection pipe 7 is attached to the bottom of the water case 1, the water inlet channel 3 is installed on the top of the water case 1, the water inlet channel 3 is bent along the outer circumference of the water case 1 and extends to the bottom of the water case 1, and communicates with the injection pipe 7.

[0169] In an embodiment of the present invention, a venturi pipe 310 is installed on the input water channel 3, and the venturi pipe 310 is installed horizontally on the upper part of the water case 1. The input water channel 3 extends from the outlet end of the venturi pipe 310 to the left or right side of the water case 1, extends downward along the left or right side wall of the water case 1 to the bottom of the water case 1, is bent and extends toward the outlet end of the injection pipe 7 at the bottom of the water case 1, and communicates with the intake end of the injection pipe 7.
