Description

Technical Field

[0001] The present invention belongs to the field of clothing treatment additive delivery equipment, and in particular relates to clothing treatment equipment and an automatic additive delivery device thereof. Background Art

[0002] Traditional washing machines require the user to manually add detergent based on experience before the wash begins, increasing the user's workload and easily leading to incomplete washing or wasted detergent due to improper dosage control. Therefore, automatic detergent dosing technology has been proposed in the related art. A detergent dispenser contains a detergent additive box and softener sufficient for multiple washes, which are automatically added as needed during each wash. The detergent dispenser also contains various other detergent additive boxes.

[0003] Numerous patent applications have been filed for automatic detergent dispensing devices. Chinese patent application number CN200610136059.9 discloses a detergent dispenser for a washing machine equipped with a siphon unit and a detergent box. Detergent is injected into the box, and wash water is then added to the box to dilute the detergent, which is then discharged from the siphon unit into the washing tub. This invention addresses the issue of concentrated detergent directly entering the washing tub, potentially damaging laundry. However, it fails to accurately control the amount of detergent added.

[0004] Chinese patent application number CN201610797034.7 discloses a detergent dispensing device for a washing machine. The device comprises a storage chamber defining a slot for a special detergent box. The slot is provided with a first and a second ejector pin for puncturing the special detergent box. The first ejector pin has a water inlet hole, and the second ejector pin has a water outlet hole. Both the first and second ejector pins are configured to pierce the special detergent box, so that the inlet and outlet holes communicate with each other, connecting the interior space of the special detergent box. In this invention, water enters the detergent box through the inlet hole and flows out through the outlet hole, mixing the detergent and flowing into the washing machine. The detergent box is single-use and must be installed for each wash cycle.

[0005] Chinese patent application number CN201710390864 discloses a washing additive box and a washing machine, wherein the washing additive box includes a box body, the box body includes a liquid outlet, and the liquid outlet is detachably provided with a liquid outlet structure, the liquid outlet structure including a one-way valve. The washing machine also includes a connecting structure, which is a cylindrical structure with a flow channel formed therein. One end is used to cooperate with the washing additive box to open the one-way valve, and the other end is used to communicate with the washing machine's delivery pipe. The side wall of the end used to cooperate with the washing additive box is provided with an opening connected to its internal flow channel, so that when the end pushes against the piston, the opening drains the washing additive into the flow channel of the connecting structure, and then enters the washing machine through the delivery pipe.

[0006] The above invention requires a push pin to open the sealing port of the washing additive box during the dispensing process. When the push pin is separated from the sealing port during the pulling and drawing process of the washing additive box, the washing liquid on the push pin will flow out and contaminate the installation chamber of the additive box.

[0007] In view of this, the present invention is proposed. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide an automatic additive delivery device, which aims to set a retractable liquid collecting unit on the outside of the connecting unit connecting the additive storage box and the delivery waterway. When the additive storage box is pulled out, the liquid collecting unit extends to receive the additives adhered to the outside of the connecting unit. When the additive storage box is put in, the liquid collecting unit retracts so that the connecting unit can connect the additive storage box and the delivery waterway. The above scheme does not affect the ability of the connecting unit to connect the additive storage box and the delivery waterway, and can also prevent additives from flowing into the chamber during the pulling and drawing process of the additive storage box.

[0009] Another object of the present invention is to provide a clothes processing device comprising the above-mentioned automatic additive delivery device.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0024] Preferably, when the liquid collecting unit is extended, it covers the end of the ejector pin used to push open the liquid outlet of the additive storage box;

[0025] Preferably, the cross section of the ejector pin has a center and a plurality of guide portions radiating outward from the center;

[0026] Preferably, the cross section of the ejector pin is in the shape of a cross.

[0027] Furthermore, the liquid collecting unit includes:

[0028] a sleeve, sleeved on the outside of the guide tube and the ejector pin, with a space margin between the ejector pin and the inner wall of the sleeve constituting a liquid collecting chamber of the liquid collecting unit for collecting additives;

[0029] The elastic member is sleeved on the outside of the guide tube and arranged between the sleeve and the chamber to keep the sleeve in the tendency to extend.

[0030] Furthermore, in the first state, a distance between an end of the sleeve away from the elastic member and an end of the ejector pin is smaller than a distance between an end of the guide tube away from the elastic member and an end of the ejector pin;

[0031] In the above solution, when the additive liquid storage box is placed in, the liquid collecting chamber cooperates with the diversion channel to form an additive channel from the additive liquid storage box to the injection waterway.

[0032] Furthermore, the outer portion of the sleeve is provided with a first stopper protruding radially outward, and both ends of the elastic member respectively contact the first stopper and the side wall of the chamber;

[0041] Preferably, at least two convex ribs protruding outward are provided on the outside of the guide tube along the circumferential direction, and a recessed portion between two adjacent convex ribs forms a first groove, and the first sealing unit is provided in the first groove.

[0042] Furthermore, at least two ribs protruding outward are circumferentially provided on the outer portion of one end of the sleeve away from the elastic member, and the recessed portion between two adjacent ribs forms a second groove.

[0043] A second sealing unit is disposed in the second groove.

[0044] A clothing processing device comprises the automatic additive delivery device as described above.

[0045] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0046] 1. The present invention provides a retractable liquid collecting unit on the outside of the connecting unit connecting the additive liquid storage box and the water supply channel. When the additive liquid storage box is pulled out, the liquid collecting unit extends to collect the additives adhering to the outside of the connecting unit. When the additive liquid storage box is inserted, the liquid collecting unit retracts, so that the connecting unit can connect the additive liquid storage box and the water supply channel, thereby preventing the additives from flowing into the chamber during the withdrawal of the additive liquid storage box.

[0047] 2. The present invention utilizes an elastic member to maintain the sleeve's extension tendency, thereby realizing automatic extension of the sleeve. When the additive storage box is taken out of the chamber, the elastic member enables the sleeve to follow the ejector pin very well, and the end face of the sleeve is in close contact with the end face of the liquid outlet of the additive storage box, so that the additive outside the ejector pin can all drip into the sleeve.

[0048] 3. The present invention provides a second stopper and a slide groove that cooperate with each other on the guide tube and the sleeve to limit the sleeve, so that the sleeve cannot fall off from the guide tube under the action of the elastic member. At the same time, it can also cooperate with the stopping effect of the liquid outlet to retract the sleeve. Moreover, the connection relationship between the second stopper and the slide groove can also realize the detachable connection between the sleeve and the guide tube, and the structure is simple and feasible.

DETAILED DESCRIPTION

[0057] 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.

[0058] In the description of the present invention, it should be noted that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "inside" and "outside" indicate directions or positional relationships 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 should not be understood as limiting the present invention.

[0059] 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.

[0060] like Figures 1 to 4 As shown, the present invention provides a clothing treatment device and an automatic additive dispensing device therefor. The automatic additive dispensing device comprises a chamber 1, a communication unit, and a liquid collection unit. When a wash program is running, the control unit of the clothing treatment device controls the automatic additive dispensing device to automatically dispense the required additive based on information such as the laundry load, load material, and water level.

[0061] The communication unit is provided in the chamber 1 for connecting the additive storage box with the injection water channel 14. The liquid collecting unit is telescopically sleeved on the outside of the communication unit along the axial direction and has a first state and a second state.

[0062] In the first state, the liquid collecting unit is retracted, and one end of the communication unit protrudes from the liquid collecting unit and is communicated with the additive storage box.

[0063] In the second state, the liquid collecting unit is extended, and one end of the communication unit is located inside the liquid collecting unit, so that the liquid collecting unit can receive additives outside the communication unit.

[0064] Specifically, chamber 1 is used to house an additive liquid storage box, which can be a disposable or reusable container. The additive liquid storage box has a liquid outlet. When the additive liquid storage box is placed in chamber 1, a connecting unit opens the liquid outlet of the storage box, thereby connecting the additive liquid storage box with the water supply channel 14 of the laundry treatment device. At least a portion of the connecting unit will extend into the liquid outlet of the additive liquid storage box, resulting in additive adhering to the exterior of some of the connecting unit.

[0065] When the additive storage box is pulled out from the chamber 1, the additives adhered to the outside of the connecting unit will drip into the liquid collecting unit sleeved outside the connecting unit, preventing the additives from falling into the chamber 1, contaminating the chamber 1 and causing bacteria to grow.

[0066] In some embodiments of the present invention, Figures 1 to 4 As shown, the communication unit includes a flow guide tube 2 and a ejector pin 3.

[0067] The flow guide pipe 2 is arranged in the chamber 1 and has a flow guide channel 4 for allowing additives to pass through, and is used to communicate with the injection water channel 14.

[0068] The ejector pin 3 is arranged in the guide tube 2. There is a space margin between the ejector pin 3 and the inner wall of the guide tube 2 to form the guide channel 4. The length of the ejector pin 3 is greater than the length of the guide tube 2. One end of the ejector pin 3 protrudes from the outside of the guide tube 2 to push open the liquid outlet of the additive storage box.

[0069] The liquid collection unit is retractably disposed outside the flow guide tube 2 and the ejector pin 3. In a first state, the liquid collection unit is retracted, with one end of the ejector pin 3 protruding from the liquid collection unit to push open the liquid outlet of the additive storage box. In a second state, the liquid collection unit is extended, with one end of the ejector pin 3 located within the liquid collection unit, enabling the liquid collection unit to receive additives outside the ejector pin 3.

[0070] In detail, a one-way valve (not shown in the figure) is provided at the liquid outlet of the additive storage box. The one-way valve includes a valve body and a spring that causes the valve body to contract. When the additive storage box is placed in the chamber 1, the ejector pin 3 pushes open the valve body of the one-way valve, so that the liquid outlet of the additive storage box is opened and can be connected to the guide channel 4 of the guide tube 2. At the same time, the liquid outlet of the additive storage box drives the liquid collecting unit to contract, so that one end of the ejector pin 3 can be exposed from the liquid collecting unit, which is used to push open the liquid outlet of the additive storage box and connect the guide channel 4 with the additive storage box. When the additive storage box is pulled out of the chamber 1, the spring of the one-way valve pushes out the valve body, so that the liquid outlet of the additive storage box is closed. At the same time, the liquid collecting unit is extended, and the ejector pin 3 is covered in the liquid collecting unit and receives the additive outside the ejector pin 3.

[0071] In a preferred embodiment, the liquid collecting unit, when extended, covers the end of the ejector pin 3 that is used to push open the liquid outlet of the additive storage box. In the above embodiment, when the liquid collecting unit is extended, the end of the ejector pin 3 that is used to push open the liquid outlet of the additive storage box can be covered, so that any additive adhering to the outside of the ejector pin 3 can drip into the liquid collecting unit, further improving the leakage prevention effect.

[0072] In a preferred solution, the cross section of the ejector pin 3 has a center and a plurality of guide portions radiating outward from the center; the space between the guide portions and the inner wall of the guide tube 2 constitutes the guide channel 4.

[0073] In a further solution, the cross section of the ejector pin 3 is in the shape of a cross.

[0074] The above solution can increase the strength of the ejector pin 3 and improve the stability of the ejector pin 3 in pushing open the one-way valve when the additive storage box is placed in the chamber 1 .

[0075] In a further embodiment, the ejector pin 3 is configured to have a tapered end for opening the one-way valve of the additive reservoir, so that the ejector pin 3 can be inserted into the liquid outlet of the additive reservoir. Alternatively, the one-way valve body may have a notch on the outward side thereof for the ejector pin 3 to be inserted into the notch.

[0076] In further solutions, such as Figure 3 and Figure 4 As shown, the liquid collecting unit includes a sleeve 5 and an elastic member 6.

[0077] The sleeve 5 is sleeved over the exterior of the guide tube 2 and the ejector pin 3. A space is left between the ejector pin 3 and the inner wall of the sleeve 5 to form a liquid collection chamber 7 of the liquid collection unit for collecting external additives from the ejector pin 3. The elastic member 6 is sleeved over the exterior of the guide tube 2, disposed between the sleeve 5 and the chamber 1, to maintain the sleeve 5's tendency to extend.

[0078] In the above solution, the elastic member 6 is used to keep the sleeve 5 in the extension tendency, so that the sleeve 5 can be automatically extended. When the additive storage box is taken out of the chamber 1, the elastic member 6 can make the sleeve 5 have a good followability with the ejector pin 3. The end face of the sleeve 5 is in close contact with the end face of the liquid outlet of the additive storage box, so that the additive outside the ejector pin 3 can all drip into the sleeve 5.

[0079] In a further embodiment, when the liquid collecting unit is in a contracted state, the distance between the end of the sleeve 5 away from the elastic member 6 and one end of the ejector pin 3 is smaller than the distance between the end of the guide tube 2 away from the elastic member 6 and one end of the ejector pin 3.

[0080] Specifically, there is a space margin between the ejector pin 3 and the inner wall of the sleeve 5 to form a liquid collecting chamber 7 , and the liquid collecting chamber 7 cooperates with the guide channel 4 to form an additive channel from the additive storage box to the injection water channel 14 .

[0081] In detail, as previously mentioned, the length of ejector pin 3 is greater than that of flow conduit 2. Therefore, a portion of ejector pin 3 is disposed within flow conduit 2, while a portion is exposed outside of the conduit 2. When sleeve 5 is sleeved over ejector pin 3, a margin of space exists between the portion of ejector pin 3 exposed within flow conduit 2 and the inner wall of sleeve 5, forming a liquid collection chamber 7 for collecting additives.

[0082] A drainage channel is provided on the side of the liquid outlet of the additive storage box facing the ejector pin 3. When the additive storage box is placed in the chamber 1, the sleeve 5 and the ejector pin 3 enter the drainage channel at the same time. When the additive storage box is completely placed in the chamber 1, the liquid outlet of the additive storage box stops the sleeve 5, causing the sleeve 5 to compress the elastic member 6 and retract, while the ejector pin 3 continues to push open the valve body of the one-way valve to open the liquid outlet.

[0083] At this time, the additive in the additive storage box can enter the liquid collecting chamber 7 of the sleeve 5 through the liquid outlet, then enter the diversion channel 4 of the diversion pipe 2, and then enter the water channel 14 of the clothing processing equipment and finally enter the clothing processing barrel of the clothing processing equipment.

[0084] It is understandable that in order to facilitate the sleeve 5 to enter the drainage channel of the additive storage box, the sleeve 5 is configured as a variable diameter structure, with the end with a larger diameter connected to the guide tube 2 and the end with a smaller diameter being sleeved on the outside of the ejector pin 3.

[0085] In specific plans, such as Figure 4 As shown, a first stopper 8 protruding radially outward is provided on the outside of the sleeve 5 , and two ends of the elastic member 6 respectively contact the first stopper 8 and the side wall of the chamber 1 .

[0086] When the additive storage box is put in, the sleeve 5 retracts and compresses the elastic member 6 through the first stopper 8, so that the elastic member 6 is in a compressed state; when the additive storage box is pulled out, the elastic member 6 pushes the first stopper 8 under the action of its own restoring force to extend the sleeve 5.

[0087] Preferably, the first stopping portion 8 is an annular boss, and the elastic member 6 is a spring.

[0088] In the above solution, the first stop portion 8 is configured as an annular boss, which can increase the effective area of the elastic member 6 and improve the stability of the sleeve 5 when it is extended.

[0089] In a further solution, a second stopper 9 protruding radially outward is provided on the outside of the flow guide tube 2 , and a sliding groove 10 extending axially is provided on the sleeve 5 .

[0090] When the sleeve 5 is retracted / extended outside the guide tube 2 , both ends of the slide groove 10 respectively contact the second stopper 9 to limit the sleeve 5 .

[0091] Preferably, the second stopping portion 9 is a bump.

[0092] In the above scheme, a second stopper 9 and a slide groove 10 that cooperate with each other are provided on the guide tube 2 and the sleeve 5 to limit the sleeve 5 so that the sleeve 5 cannot fall off from the guide tube 2 under the action of the elastic member 6. At the same time, the sleeve 5 can also be retracted in cooperation with the stopping effect of the liquid outlet.

[0093] In some embodiments of the present invention, the sleeve 5 is detachably connected to the flow guide tube 2, so that the user can remove the sleeve 5 from the flow guide tube 2 for cleaning, thereby preventing the sleeve 5 from being filled with too much additive and causing it to overflow.

[0094] In a preferred solution, the second stop portion 9 is engaged with the sliding groove 10 to enable the sleeve 5 to be detachably connected to the flow guide pipe 2 .

[0095] Further preferably, the second stopper 9 is pressably arranged on the outside of the flow guiding tube 2 so that the sleeve 5 and the flow guiding tube 2 are detachably connected.

[0096] In the above solution, the detachable connection between the sleeve 5 and the flow guide pipe 2 is achieved by utilizing the connection relationship between the second stopper 9 and the slide groove 10 , and the structure is simple and feasible.

[0097] In some embodiments of the present invention, Figure 4 As shown, a first sealing unit is provided between the sleeve 5 and the flow guide tube 2 for sealing the liquid collecting chamber 7 to prevent the additive in the liquid collecting chamber 7 from flowing out from the other end of the sleeve 5 .

[0098] In a preferred solution, at least two convex ribs protruding outward are circumferentially provided on the exterior of the flow guide tube 2 , and a recessed portion between two adjacent convex ribs forms a first groove 11 , in which the first sealing unit is provided.

[0099] In detail, three convex ribs are provided on the outside of one end of the flow guide tube 2 away from the side wall of the chamber 1 . The three convex ribs form two recessed portions. The recessed portions form a first groove 11 . The first sealing unit is provided in the first groove 11 .

[0100] Preferably, the first sealing member is a sealing ring, the size of which matches the size of the first groove 11 , and plays a sealing role when the sleeve 5 is extended and retracted outside the guide tube 2 .

[0101] In some embodiments of the present invention, Figure 4 As shown, at least two ribs protruding outward are circumferentially provided on the outer portion of one end of the sleeve 5 away from the elastic member 6 , and a recess between two adjacent ribs forms a second groove 12 , in which a second sealing unit 13 is provided.

[0102] In the above solution, a second sealing unit 13 is provided on the outside of the end of the sleeve 5 away from the elastic member 6, that is, the end close to the liquid outlet of the additive storage box, which can increase the sealing performance between the sleeve 5 and the drainage channel of the additive storage box and prevent the additive from leaking from the additive storage box.

[0103] Preferably, the second sealing member is a sealing ring, and the size of the sealing ring is adapted to the size of the second groove 12 .

[0104] The clothing processing device of the present invention includes the above-mentioned automatic additive delivery device, by arranging a retractable liquid collecting unit on the outside of the connecting unit connecting the additive liquid storage box and the delivery water channel 14. When the additive liquid storage box is pulled out, the liquid collecting unit extends to receive the additives adhered to the outside of the connecting unit. When the additive liquid storage box is put in, the liquid collecting unit retracts, so that the connecting unit can connect the additive liquid storage box and the delivery water channel 14, thereby preventing additives from flowing into the chamber 1 during the drawing and pulling process of the additive liquid storage box, thereby improving the user experience.

[0105] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as above in terms of a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with this patent can make slight changes or modifications to equivalent embodiments using the above technical content without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
