Description

Technical Field

[0001] The present invention belongs to the technical field of clothing cleaning, and in particular relates to a dispensing device. Background Art

[0002] The laundry treatment device is a frequently used household appliance. It is equipped with a dispensing mechanism, which primarily comprises a water box connected to the device's water inlet and a dispenser box housed within the water box. The dispenser box is typically retractable within the water box, allowing the user to remove the dispenser box from the water box and add detergent. Thrust structures are typically installed on the top or left and right side walls of the dispenser box. Once the dispenser box is inserted into the water box, the thrust structures engage the internal structure of the water box, limiting its position and preventing it from completely dislodging if pulled.

[0003] However, the above solution has the following problems: some water boxes adopt the method of setting the water outlet end of the water inlet pipe on the rear side of the distributor box, and the rear side of the distributor box is provided with a connecting pipe extending forward and backward, the front end of the connecting pipe is connected to the liquid storage chamber of the distributor box, and the rear end is connected to the water outlet end of the water inlet pipe, so that the incoming water directly enters the liquid storage chamber; when the incoming water pressure is large, the water inlet pipe exerts a large forward thrust on the connecting pipe and the distributor box, and the existing thrust structure cannot ensure the stable fixation of the distributor box, and the incoming water flow is likely to push the distributor box out of the water box, causing the washing machine to fail to operate normally, seriously affecting the user experience; in addition, every time the user wants to take out the distributor box for cleaning, he must press the limit structure with one hand and pull the distributor box with the other hand to complete it, which is inconvenient to use.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a dispensing device. By setting a thrust structure that needs to be manually controlled, the thrust structure can be stably abutted against the water box when the handle unit is not subjected to force. Under different force conditions, the function of partially pulling out the dispenser box and completely pulling out the dispenser box can be achieved with one hand; at the same time, when the water pressure of the incoming water is large, the thrust structure can also ensure the stable limiting of the dispenser box, thereby solving the technical problem that the incoming water will push the dispenser box out of the water box.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: a dispensing device, including a water box, which is internally provided with a dispenser box that can be pulled out and pushed back from the front side; a thrust structure, which is arranged on the dispenser box; the thrust structure includes at least a first limiting unit, which at least partially protrudes from the outer wall of the dispenser box, and when the dispenser box is located in the first position inside the water box, the first limiting unit abuts against the water box; a hand-accommodating cavity for hand insertion is provided on the front side of the dispenser box, and the thrust structure also includes a handle unit arranged in the hand-accommodating cavity, and the handle unit is connected to the first limiting unit through a connecting unit. Under the action of external force, the handle unit can drive the first limiting unit to move toward the inside of the dispenser box to a first compressed position intersecting with the water box.

[0007] Furthermore, the left and right sides of the handle unit are respectively provided with horizontal hinge shafts with protruding surfaces, and each hinge shaft is respectively hinged to the side wall of the hand accommodating cavity. The handle unit drives the first limiting unit to rotate around the hinge shaft of the connecting unit through the connecting unit.

[0008] Furthermore, each hinge axis is respectively arranged on the left and right sides of the rear end of the handle unit; the connecting unit extends upward from front to back, the front end of the connecting unit is connected to the rear end of the handle unit, and the rear end of the connecting unit is provided with a first limiting unit that bends and extends upward.

[0009] Furthermore, a movable cavity is provided inside the distributor box to provide space for the connection unit and the first limiting unit to rotate, and a first limiting hole connected to the movable cavity is provided at the top of the distributor box; the upper end of the first limiting unit protrudes from the top of the distributor box through the first limiting hole and abuts against the water box.

[0010] Furthermore, the thrust structure also includes a second limiting unit, which at least partially protrudes from the outer wall of the dispenser box, so that when the dispenser box is pulled out to the second position, the second limiting unit abuts against the water box; the second limiting unit is connected to the connecting unit through the traction unit, and under the action of external force, the handle unit drives the protruding end of the second limiting unit to move toward the inside of the dispenser box to a second compression position that intersects with the water box.

[0011] Furthermore, the second limiting unit is an elastic structure, and the front side of the second limiting unit is connected to the traction unit; the handle unit drives the traction unit to pull the second limiting unit, driving the protruding end of the second limiting unit to compress and deform into the inside of the dispenser box.

[0012] Furthermore, the second limiting unit is a plate-like structure extending forward and backward, and the front and rear ends of the plate-like second limiting unit are respectively connected to the traction unit and the distributor box. The middle part of the plate-like second limiting unit is set as a protrusion bent toward the outside of the distributor box, and the protrusion protrudes from the outer surface of the distributor box.

[0013] Furthermore, protruding hinge shafts are respectively provided on the left and right sides of the rear end of the handle unit; the connecting unit extends upward from front to back, the front end of the connecting unit is connected to the rear end of the handle unit, and the middle or rear end of the connecting unit is connected to the traction unit.

[0014] Furthermore, the front end of the traction unit is located above the line between the rear end of the handle unit and the second limiting unit.

[0015] Furthermore, the front interior of the dispenser box is hollow to form a hand accommodating cavity, and a hand extending hole communicating with the hand accommodating cavity is opened on the front surface of the dispenser box.

[0016] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: by setting a thrust structure that requires manual control, the thrust structure can stably abut against the water box when the handle unit is not subjected to force, so that the first limiting unit can be made of a material with high hardness and non-deformable properties, thereby ensuring the stability of the thrust structure in limiting the distributor box; at the same time, when the water pressure of the incoming water is large, the thrust structure can also ensure the stable limiting of the distributor box, preventing the incoming water from pushing the distributor box out of the water box.

[0017] At the same time, the present invention has a simple structure, significant effects, and is suitable for popularization and use.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0032] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0033] like Figure 1-7 As shown, in an embodiment of the present invention, a dispensing device is introduced, including a water box 3, which is internally provided with a dispenser box 1 that can be pulled out and pushed back from the front side; a thrust structure 2, which is arranged on the dispenser box 1; the thrust structure 2 includes at least a first limiting unit 230, which at least partially protrudes from the outer wall of the dispenser box 1, and when the dispenser box 1 is located in the first position inside the water box 3, the first limiting unit 230 abuts against the water box 3; a hand-accommodating cavity 111 for a hand to be inserted into is provided on the front side of the dispenser box 1, and the thrust structure 2 also includes a handle unit 210 arranged in the hand-accommodating cavity 111, and the handle unit 210 is connected to the first limiting unit 230 via a connecting unit 220. Under the action of external force, the handle unit 210 can drive the first limiting unit 230 to move toward the inside of the dispenser box 1 to a first compressed position intersecting with the water box 3.

[0034] Through the above-mentioned setting, by setting a thrust structure 2 that needs to be manually controlled, the thrust structure 2 can be stably abutted against the water box 3 when the handle unit 210 is not subjected to force, so that the first limiting unit 230 can be made of a material with high hardness and non-deformable, thereby ensuring the stability of the thrust structure 2 in limiting the distributor box 1; at the same time, when the water pressure of the incoming water is large, the thrust structure 2 can also ensure the stable limiting of the distributor box 1, preventing the incoming water from pushing the distributor box 1 out of the water box 3.

[0035] In an embodiment of the present invention, horizontal hinge shafts 211 with protruding surfaces are respectively provided on the left and right sides of the handle unit 210, and each hinge shaft 211 is respectively hinged to the side wall of the hand accommodating cavity 111. The handle unit 210 drives the first limiting unit 230 to rotate around the hinge shaft 211 of the connecting unit 220 through the connecting unit 220; the user rotates the handle unit 210 with his fingers to control the first limiting unit 230 to rotate toward the inside of the dispenser box 1, so that the dispenser box 1 is unlocked from the water box 3. The operation is convenient and suitable for promotion.

[0036] In an embodiment of the present invention, the handle unit 210 is a sheet-like structure; the handle unit 210 is arranged to be tilted downward from back to front, and the rear end of the handle unit 210 is connected to the connecting unit 220; the front end of the handle unit 210 is arranged to be spaced apart from the front side and / or rear side wall of the hand accommodating cavity 111 by one end; and is used to provide a moving space for the lower end of the handle unit 210.

[0037] In an embodiment of the present invention, each hinge shaft 211 is respectively arranged on the left and right sides of the rear end of the handle unit 210; the connecting unit 220 extends upward from front to back, and the front end of the connecting unit 220 is connected to the rear end of the handle unit 210, and the rear end of the connecting unit 220 is provided with a first limiting unit 230 that bends and extends upward; preferably, the front end of the handle unit 210 is arranged at a distance from the front side chamber wall of the hand accommodating chamber 111.

[0038] Through the above arrangement, the handle unit 210 is rotatably installed in the hand accommodating cavity 111. After the user inserts his hand into the hand accommodating cavity 111, he moves the handle unit 210 forward with his fingers to retract the first limiting unit 230 into the dispenser box 1; then, he pulls the dispenser box 1 forward with his hand to at least partially pull out the dispenser box 1; the force directions of unlocking the first limiting unit 230 and pulling out the dispenser box 1 are the same, thereby simplifying the complexity of the operation and bringing convenience to the user.

[0039] In an embodiment of the present invention, a torsion spring (not shown in the figure) is sleeved on the hinge shaft 211, and the two ends of the torsion spring are respectively connected to the handle unit 210 and the cavity wall of the hand accommodating cavity 111, so that the handle unit 210 always remains in the middle position of the hand accommodating cavity 111 and can be reset after the pulling force disappears.

[0040] In actual application, the torsion force of the torsion spring is very small, and there is a certain friction between the dispenser box 1 and the water box 3. When the user is ready to pull open the dispenser box 1, the finger pulls the handle unit 210 outward, first overcoming the resistance of the torsion spring, unlocking the first limit unit 230, and then overcoming the friction between the dispenser box 1 and the water box 3 to pull out the dispenser box 1. The whole process is no different from the normal operation of other types of dispenser boxes.

[0041] In the embodiment of the present invention, the handle unit 210 , the connecting unit 220 and the first limiting unit 230 are integrated.

[0042] In an embodiment of the present invention, an active cavity is provided inside the distributor box 1 for providing space for the connection unit 220 and the first limiting unit 230 to rotate, and a first limiting hole 161 connected to the active cavity is provided on the top of the distributor box 1; the upper end of the first limiting unit 230 protrudes from the top of the distributor box 1 through the first limiting hole 161 and abuts against the water box 3; by hiding the connection unit 220 in the active cavity and providing a first limiting hole 161 on the top of the active cavity for the first limiting unit 230 to extend, dust and water are prevented from falling into the space where the connection unit 220 and the first limiting unit 230 are located, and the occurrence of difficulty in rotation of the thrust structure 2 due to dust accumulation is prevented. At the same time, the overall appearance and neatness of the distributor box 1 are also improved.

[0043] In the embodiment of the present invention, a mounting groove recessed inward is provided on the front surface of the water box 3 , and the dispenser box 1 is drawable and arranged in the mounting groove.

[0044] In an embodiment of the present invention, a downwardly protruding limiting protrusion is provided on the top of the installation groove. When the dispenser box 1 is located at the first position, the first limiting unit 230 abuts against the rear surface of the limiting protrusion.

[0045] In an embodiment of the present invention, a first limiting groove 311 recessed inward is provided on the top groove wall of the installation groove. When the dispenser box 1 is located at the first position, the first limiting unit 230 abuts against the front groove wall of the first limiting groove 311 .

[0046] In the embodiment of the present invention, the first limiting unit 230 is tilted forward from bottom to top, so that when the dispenser box 1 is pulled out and pushed into the water box 3, the first limiting unit 230 is pressed down by the outer wall of the water box 3 and smoothly enters the water box 3.

[0047] In the embodiment of the present invention, the front side wall of the first limiting groove 311 is tilted forward from bottom to top, and the first limiting unit 230 is in contact with the front side wall of the first limiting groove 311 .

[0048] In an embodiment of the present invention, the top of the front side groove wall of the first limiting groove 311 is against the connection between the first limiting unit 230 and the connecting unit 220; so that the entire front side surface of the first limiting unit 230 is fitted with the corresponding groove wall, thereby increasing the contact area between the two, making the water box 3 more stable in limiting the distributor box 1, and further improving the impact resistance of the distributor box 1 in the first position.

[0049] In the embodiment of the present invention, the rear side wall of the first limiting groove 311 is spaced a certain distance from the first limiting unit 230 to provide space for the first limiting unit 230 to rotate in the first limiting groove 311 .

[0050] In the prior art, a second limiting unit 250 is usually provided on the outer surface of the dispenser box 1. When the dispenser box 1 is partially pulled out, the second limiting unit 250 abuts against the internal structure of the water box 3 to prevent the dispenser box 1 from being completely pulled out. However, when it is necessary to control the disassembly of the dispenser box 1, one hand is required to hold the dispenser box 1 and the other hand presses the front end of the second limiting structure, which requires both hands to be used at the same time to achieve the disassembly of the dispenser box 1, which lacks convenience. In order to solve the above technical problems, the following technical solutions are proposed.

[0051] In an embodiment of the present invention, the thrust structure 2 also includes a second limiting unit 250, which at least partially protrudes from the outer wall of the distributor box 1, so that when the distributor box 1 is pulled out to the second position, the second limiting unit 250 abuts against the water box 3; the second limiting unit 250 is connected to the connecting unit 220 through the traction unit 240, and the handle unit 210 drives the protruding end of the second limiting unit 250 to move toward the inside of the distributor box 1 to a second compressed position intersecting with the water box 3 under the action of external force.

[0052] Through the above arrangement, by arranging the handle unit 210 that compresses the second limiting unit 250 that controls the stop structure on the front side of the dispenser box 1, the user can hold the front side of the dispenser box 1 with one hand and operate the handle unit 210, so that the user can disassemble the dispenser box 1 with only one hand, which brings convenience to the user; at the same time, the second limiting unit 250 and the first limiting unit 230 are respectively controlled by the same handle unit 210, which further facilitates the user's use.

[0053] In an embodiment of the present invention, the second limiting unit 250 is an elastic structure, and the front side of the second limiting unit 250 is connected to the traction unit 240; the handle unit 210 drives the traction unit 240 to pull the second limiting unit 250, driving the protruding end of the second limiting unit 250 to compress and deform toward the inside of the dispenser box 1; so as to simplify the transmission structure between the handle unit 210 and the second limiting unit 250 and reduce the complexity of the internal components of the dispenser box.

[0054] In an embodiment of the present invention, the traction unit 240 is a pull rope without elasticity or with an elastic coefficient greater than the elastic coefficient of the second limiting unit 250; or, the traction unit 240 is a strip-shaped rib plate.

[0055] In an embodiment of the present invention, the second limiting unit 250 is a plate-like structure extending forward and backward, and the front and rear ends of the second limiting unit 250 are respectively connected to the traction unit 240 and the dispenser box 1. The middle part of the second limiting unit 250 is set as a protrusion 251 bent toward the outside of the dispenser box 1, and the protrusion 251 protrudes from the outer surface of the dispenser box 1; the deformable protrusion 251 is formed by the self-bending of the plate-like second limiting structure, so that when the front end of the second limiting structure is pulled forward, the bent protrusion 251 is synchronously contracted toward the inside of the dispenser box 1.

[0056] In an embodiment of the present invention, protruding hinge shafts 211 are respectively provided on the left and right sides of the rear end of the handle unit 210; the connecting unit 220 extends upward from front to back, the front end of the connecting unit 220 is connected to the rear end of the handle unit 210, and the middle part or the rear end of the connecting unit 220 is connected to the traction unit 240.

[0057] In the embodiment of the present invention, a through hole is formed in the middle of the connecting unit 220 , and a front end of the pulling unit 240 is fixed on the through hole.

[0058] In a preferred embodiment of the present invention, the front end of the traction unit 240 is located above the line between the rear end of the handle unit 210 and the second limiting unit 250; more specifically, the front end of the inclined handle unit 210 is arranged at a certain distance from the cavity walls on the front and rear sides of the hand accommodating cavity 111.

[0059] Through the above-mentioned arrangement, when the lower end of the handle unit 210 is pulled forward, the connecting unit 220 drives the front end of the traction unit 240 to move downward and backward, thereby shortening the distance between the front end of the traction unit 240 and the second limiting unit 250. When the traction unit 240 is a pull rope, the connecting unit 220 will not drive the protruding end of the second limiting unit 250 to deform; or, when the traction unit 240 is a rib plate, the traction unit 240 squeezes the front end of the second limiting unit 250, thereby increasing the height of its upward protrusion, so that when the user unlocks the first limiting unit 230 and pulls out the dispenser box 1, the stability of the abutment limit between the second limiting unit 250 and the water box 3 is stronger.

[0060] Furthermore, when the lower end of the handle unit 210 moves backward, the connecting unit 220 drives the front end of the traction unit 240 to move upward and forward, thereby extending the distance between the front end of the traction unit 240 and the second limiting unit 250, causing the traction unit 240 to pull the front end of the second limiting unit 250 forward, reducing the height of its upward protrusion, and causing the second limiting unit 250 to be misaligned with the water box 3, thereby unlocking the second limiting unit 250.

[0061] The user's operating steps for pulling out the dispenser box 1 are as follows: first, use your fingers to push the handle unit 210 to rotate forward, unlock the first limiting structure, and then pull the dispenser box 1 from the first position to the second position; then, by pushing the handle unit 210 backward, unlock the second limiting structure, and then completely pull the dispenser box 1 out from the second position.

[0062] Through the above arrangement, by adding the operation process of switching the toggling direction of the handle unit 210, it is possible to effectively prevent the user from accidentally pulling out the entire dispenser box 1 when replenishing detergent in the dispenser box 1.

[0063] In an embodiment of the present invention, the first limiting unit 230 is set at a certain distance from the front side hole wall of the first limiting hole 161; when the user drives the handle unit 210 to move backward and rotate, the connecting unit 220 synchronously drives the first limiting unit 230 to rotate forward, and the spacing distance is set to provide rotation space for the first limiting unit 230.

[0064] In an embodiment of the present invention, the traction unit 240 and the second limiting unit 250 are arranged in the active cavity, and a second limiting hole 162 communicating with the active cavity is opened on the top of the distributor box 1; the protrusion 251 of the second limiting unit 250 protrudes from the top of the distributor box 1 through the second limiting hole 162 and abuts against the water box 3.

[0065] In an embodiment of the present invention, a second limiting groove 312 recessed inward is provided on the top groove wall of the water box 3 installation groove. When the dispenser box 1 is in the second position, the second limiting unit 250 abuts against the front groove wall of the second limiting groove 312. Preferably, the length of the second limiting groove 312 in the front-to-back direction is greater than or equal to the distance between the first position and the second position.

[0066] In the embodiment of the present invention, when the dispenser box 1 is located at the second position, the first limiting unit 230 is located outside the installation groove.

[0067] In an embodiment of the present invention, the front interior of the dispenser box 1 is hollow to form a hand-receiving cavity 111, and a hand-extending hole 112 connected to the hand-receiving cavity 111 is provided on the front surface of the dispenser box 1; preferably, the hand-extending hole 112 is provided on the lower half of the hand-receiving cavity 111; when the user operates the dispenser box 1, the user extends the palm of the hand into the hand-extending hole 112; then, the user bends the fingers upward to touch the handle unit 210; the user can move the handle unit 210 forward or backward according to actual needs to control the first limiting unit 230 or the second limiting unit 250 to retract into the inside of the dispenser box 1.

[0068] In an embodiment of the present invention, the washing machine includes a housing 5 for constituting the external structure of the washing machine. The housing 5 and the water box 3 are integrated; alternatively, the water box 3 is installed inside the housing 5 .

[0069] In an embodiment of the present invention, a water storage chamber 120 is provided inside the dispenser box 1 for providing space for accommodating detergent; the dispensing device also includes a water supply unit 4 for supplying water into the water storage chamber 120; a connecting pipe 130 connected to a side wall of the water storage chamber 120 is provided inside the dispenser box 1, and the liquid inlet end of the connecting pipe 130 is connected to the liquid outlet end of the water supply unit 4.

[0070] Through the above-mentioned arrangement, by providing a connecting pipe 130 connected to the side wall of the water storage chamber 120 inside the dispenser box 1, water enters the water storage chamber 120 from a horizontal direction, reducing the kinetic energy loss of the water, and the water flows in a horizontal direction, so that the water can effectively stir the detergent in the water storage chamber 120, thereby allowing the detergent to be fully dissolved in the water; in addition, the dispensing device can also conduct water to the water storage chamber 120 without providing a water tank, greatly reducing the length and complexity of the water path, thereby greatly reducing the residual amount of residual water in the dispensing device and the duration of the residual water dripping.

[0071] It should be noted that detergents are solid and / or liquid substances commonly used for treating clothes, such as laundry liquid, laundry powder, and / or softener, and / or disinfectant, and / or bleach.

[0072] In an embodiment of the present invention, the water supply unit 4 includes a docking joint 410, which is arranged on the distributor box 1 and is connected to the liquid inlet end of the connecting pipe 130, and the axis is arranged parallel to the pulling direction of the distributor box 1; a water supply pipe 420, which is used to conduct water, and the liquid outlet end is coaxially arranged with the docking joint 410, and is connected to the docking joint 410 in a switchable manner.

[0073] Through the above-mentioned arrangement, by providing a water supply pipe 420 and a docking joint 410 that can be connected and disconnected, the water supply unit 4 can supply water to the dispenser box 1 without providing a water storage tank outside the dispenser box 1, thereby reducing the space occupied by the dispensing device; more importantly, the water path for guiding water in the water storage tank is eliminated, which greatly reduces the length and complexity of the water path, thereby greatly reducing the amount of residual water in the dispensing device and the duration of the residual water dripping, avoiding the user's mistaken belief that there is a water leakage problem in the clothing processing device, and improving the user's experience.

[0074] In the embodiment of the present invention, the water supply pipe 420 is a hard pipe and is fixed inside the clothes processing device.

[0075] In an embodiment of the present invention, a docking cover 421 coaxial with the docking joint 410 is provided on the liquid outlet end of the water supply pipe 420, and the inner surface of the docking cover 421 is fitted with the outer surface of the docking joint 410; the docking cover 421 is provided to facilitate the connection between the docking joint 410 and the water supply pipe 420, and the docking cover 421 and the surface of the docking joint 410 can form a seal to prevent water leakage at the docking point between the water supply pipe 420 and the docking joint 410 when the water supply pipe 420 supplies water to the dispenser box 1.

[0076] In an embodiment of the present invention, the docking cover 421 is open, and the outer surface of the docking joint 410 is matched with the shape of the docking cover 421; so that the docking joint 410 fits with the open docking cover 421, further improving the sealing effect. At the same time, the open docking cover 421 can guide the docking joint 410 to avoid dislocation of the docking joint 410.

[0077] In the embodiment of the present invention, the docking cover 421 is a truncated cone structure, and the docking joint 410 is correspondingly configured as a truncated cone structure.

[0078] In the embodiment of the present invention, a solenoid valve 422 is provided on the water supply pipe 420 , and the solenoid valve 422 controls the on-off of the water channel in the water supply pipe 420 .

[0079] In the embodiment of the present invention, the bottom of the water box 3 is connected to a drain pipe 320 for draining the water in the water box 3. The drain pipe 320 is arranged below the docking cover 421 to directly collect and drain the water dripping from the docking cover 421.

[0080] In an embodiment of the present invention, a downwardly recessed liquid collecting trough 330 is provided at the bottom of the water box 3 on the outer periphery of the drain pipe 320, and the liquid collecting trough 330 is open to collect water at the bottom of the water box 3 to the drain pipe 320, thereby preventing water dripping from the docking cover 421 from remaining at the bottom of the water box 3.

[0081] In an embodiment of the present invention, at least part of the side wall of the water storage chamber 120 is configured as an arcuate surface, and the connecting pipe 130 is tangentially connected to the arcuate side wall; preferably, the horizontal cross-sections at various height positions of the water storage chamber 120 are circular or elliptical; further preferably, the horizontal cross-sections at various height positions of the water storage chamber 120 are circular with their centers located on the same vertical axis.

[0082] Through the above arrangement, by tangentially connecting the communicating pipe 130 to the water storage chamber 120, water forms a vortex in the water storage chamber 120, further improving the dissolution effect of the detergent.

[0083] However, the above embodiment has a problem: although the vortex formed by water in the water storage chamber 120 improves the dissolution effect of detergent, it is limited to the portion near the periphery of the water storage chamber 120. Since the linear velocity of the vortex in the middle of the water storage chamber 120 is relatively low, the water still has a poor dissolution effect on the detergent in this portion. In addition, the undissolved detergent in the peripheral portion will gradually gather in the middle of the water storage chamber 120, resulting in the problem of ineffective dissolution of the detergent. Based on the above problem, the following embodiment is proposed.

[0084] In an embodiment of the present invention, the water storage chamber 120 is a truncated cone-shaped structure; preferably, the cross-sections of the top and bottom of the truncated cone-shaped water storage chamber 120 are respectively smaller than the cross-sectional area of ​​the middle portion; another preferred embodiment is that the top cross-section of the water storage chamber 120 is larger than the bottom cross-section; during the process of water rotating along the peripheral wall of the water storage chamber 120, the combined effect of centrifugal force and the peripheral wall realizes a gradually upward spiral motion, thereby increasing the height of the water in the water storage chamber 120 and increasing the proportion of water located in the peripheral part of the water storage chamber 120, thereby increasing the overall speed of water rotation and improving the dissolution effect of the detergent.

[0085] In the embodiment of the present invention, the communication pipe 130 is connected to the bottom of the peripheral side of the truncated cone-shaped water storage chamber 120, so that water enters the water storage chamber 120 from the bottom and moves in a spiral from bottom to top more smoothly.

[0086] In the embodiment of the present invention, the communication pipe 130 extends from back to front, and the liquid outlet end of the communication pipe 130 is tangentially connected to the left or right side wall of the water storage chamber 120 .

[0087] In an embodiment of the present invention, a delivery chamber 140 is further provided in the dispenser box 1. An opening communicating with the delivery chamber 140 is provided on the upper surface of the dispenser box 1. The bottom of the delivery chamber 140 is connected to the top of the water storage chamber 120, so that the user can add detergent into the water storage chamber 120. The delivery chamber 140 is configured to be funnel-shaped with a horizontal cross-section gradually shrinking from top to bottom. The delivery chamber 140 is provided with an open opening to facilitate the user to add detergent into the water storage chamber 120. At the same time, when the water flow rate is large, the water in spiral motion can move into the funnel-shaped delivery chamber 140, thereby preventing water from flowing to the outside of the dispenser box 1 and causing water leakage in the dispenser box 1.

[0088] In the embodiment of the present invention, the bottom of the delivery chamber 140 and the top of the water storage chamber 120 are of the same shape and size.

[0089] In an embodiment of the present invention, a plurality of stirring structures 150 with protruding surfaces are distributed on the side wall of the water storage chamber 120; preferably, each stirring structure 150 is located at a different height position; by providing the stirring structure 150, the detergent collides with the stirring structure 150 during the rotation process in the water storage chamber 120, thereby achieving a stirring effect on the water.

[0090] In the embodiment of the present invention, a plurality of stirring structures 150 with protruding surfaces are distributed on the sidewall of the delivery cavity 140 .

[0091] In the embodiment of the present invention, each stirring structure 150 is a rod-shaped structure protruding from the surface, or a conical structure with a diameter gradually decreasing along the protruding direction.

[0092] In the embodiment of the present invention, a cover 142 is provided on the top of the delivery cavity 140 in an openable and closable manner.

[0093] In the embodiment of the present invention, the cover 142 is hinged to the rear chamber wall 140 of the delivery chamber.

[0094] In an embodiment of the present invention, a collecting chamber is further provided inside the dispenser box 1, and a first filter hole connected to the collecting chamber is distributed on one side wall of the water storage chamber 120; the collecting chamber is provided with a drain port for discharging the mixture of water and detergent.

[0095] Through the above arrangement, water needs to be filtered through the first filter hole before entering the collecting chamber, thereby blocking the undissolved detergent in the water in the water storage chamber 120, preventing the detergent from being discharged prematurely without sufficient stirring and dissolution; at the same time, the water in the water storage chamber 120 all flows into the collecting chamber through the first filter hole distributed at the bottom of the side wall of the collecting chamber, preventing water from remaining in the water storage chamber 120; in addition, the water is buffered in the collecting chamber, and the water that enters the collecting chamber later can be further mixed with the water that enters earlier, thereby achieving the effect of homogenizing the water, so that the detergent content in the water flowing out of the dispenser box 1 is more balanced.

[0096] In the embodiment of the present invention, the drain port is located above the liquid collecting tank 330 .

[0097] In an embodiment of the present invention, the bottom wall of the collecting chamber is tilted downward from the periphery to the drain outlet, so that water is collected toward the drain outlet and water is prevented from remaining on the bottom wall of the collecting chamber.

[0098] In the embodiment of the present invention, the water storage chamber 120 and the collecting chamber are adjacently arranged and share the same side wall.

[0099] In the embodiment of the present invention, the communication pipe 130 and the collecting chamber are respectively located on the same side of the water storage chamber 120 , and the communication pipe 130 is tangentially connected to the water storage chamber 120 .

[0100] In the embodiment of the present invention, the collecting chamber is disposed at the rear side of the water storage chamber 120, and the communicating pipe 130 is disposed at the rear side of the water storage chamber 120 and is tangentially connected to the left or right sidewall of the water storage chamber 120. Water flowing out of the communicating pipe 130 first flows toward the front side of the water storage chamber 120 and then rotates along the sidewall of the water storage chamber 120 once before reaching the sidewall having the first filter hole. This extends the water's shortest travel distance, allowing the water sufficient time to dissolve the detergent.

[0101] In an embodiment of the present invention, a second filter hole 141 is distributed on the side wall adjacent to the delivery chamber 140 and the collection chamber; the water entering the collection chamber from the delivery chamber 140 is filtered through the second filter hole 141 to prevent undissolved detergent from entering the collection chamber through the second filter hole 141.

[0102] In an embodiment of the present invention, the aperture of the second filter hole 141 is larger than that of the first filter hole; the water flow rate is increased while ensuring that the detergent can be effectively filtered.

[0103] In the embodiment of the present invention, water enters the dispenser box 1 through the water supply unit 4 and enters the water storage chamber 120 through the connecting pipe 130 to flush the detergent. The water flows in a direction parallel to the sidewalls of the water storage chamber 120. The water makes a gradually upward spiral motion along the sidewalls of the frustum-shaped water storage chamber 120. During the flow, the water collides with the stirring structure 150 on the sidewall of the water storage chamber 120, thereby stirring the detergent in the water. After rotating at least one revolution, some of the detergent flows through the first filter hole at the rear of the water storage chamber 120 into the collection chamber. The remaining water flows into the delivery chamber 140 above the water storage chamber 120 and flows through the second filter hole 141 at the rear of the delivery chamber 140 into the collection chamber. Undissolved detergent is blocked by the filter mesh provided on the first filter hole or the second filter hole 141 in the water storage chamber 120 or the delivery chamber 140. Subsequent water flow flushes out this portion of detergent, dissolving it before entering the collection chamber, thereby eliminating the undissolved detergent in the collection chamber.
