Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically, it relates to a washing machine dispensing device and a washing machine having the device. Background Technology

[0002] The detergent dispenser is an essential component of a washing machine. It is typically located between the water supply valve and the washing drum, providing different forms or types of detergents at different stages of the washing process. Currently, commonly used detergent dispensers include liquid detergents and solid detergents. Existing detergent dispensers usually use a siphon system to dispense liquid detergents and a direct water rinsing method to dispense solid detergents. Therefore, existing detergent dispensers contain compartments for detergent powder, fabric softener, and sometimes disinfectant. These designs result in large volume, require significant installation space, and are structurally complex. Furthermore, users must distinguish between the compartments when adding detergents, making operation inconvenient.

[0003] Some dispensing devices use separate dispensing boxes for liquid and solid additives, respectively. For example, a detergent box is used for laundry powder, while a detergent box is removed and replaced with a liquid detergent box for liquid detergent. These devices have small dispensing capacities, are prone to loss due to frequent replacements, and are inconvenient to operate.

[0004] Currently, there are two common methods for adding additives to washing machines: one is to manually add the additives into the washing machine; the other is to first put the additives into a dispenser box, and when the water inlet valve of the washing machine is opened, the water flow will flush the additives out of the dispenser box and into the washing tub below.

[0005] Both methods of adding additives mentioned above utilize the power generated by the washing machine's drum rotation to dissolve the additives. However, neither method can guarantee that the additives will be fully dissolved to produce the desired washing effect. First, the solubility rate of additives varies depending on the duration of drum rotation. Second, additives, especially solid forms such as laundry detergent and soap powder, may be encapsulated by the clothes to be washed before being agitated, preventing them from being rinsed away by the water flow. This results in clothes not only not being cleaned but also having residual additives attached to them. If these additives remain encapsulated by the clothes during subsequent rinsing, they may come into direct contact with the skin, potentially causing skin irritation.

[0006] Furthermore, traditional dispensing devices do not have a scheduled dispensing function. Each time detergent is dispensed, it flows directly into the washing tub. If a user adds detergent but then decides not to wash clothes, it results in detergent waste. The user will have to add detergent again the next time they want to wash clothes, and the detergent that flowed into the tub before will not dissolve completely, which will also affect the washing effect.

[0007] Therefore, how to achieve pre-positioned dispensing of solid or liquid additives while saving space and improving the dissolution effect of additives is a problem that needs to be solved.

[0008] Chinese patent CN105088688A discloses an automatic dispensing system for a washing machine and a washing machine having the automatic dispensing system. The automatic dispensing system includes: a detergent storage box with multiple detergent storage chambers; a transfer box with multiple liquid inlets and one liquid outlet, the detergent storage box being connected to the transfer box and the multiple liquid inlets corresponding one-to-one with the multiple detergent storage chambers; an electromagnetic switching unit mounted on the transfer box for selectively connecting one of the multiple liquid inlets to the one liquid outlet; and a dispensing pump with an inlet and an outlet, the inlet of the dispensing pump being connected to the one liquid outlet. This patent can only achieve automatic dispensing of liquid detergent, not solid laundry powder, and its structure is relatively complex due to the inclusion of a transfer box and dispensing pump.

[0009] In view of this, the present invention is proposed. Summary of the Invention

[0010] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a washing machine dispensing device, which uses a magnetic attraction component to allow the support component to be separably abutted against the bottom wall of the detergent box, thereby realizing the function of scheduled dispensing of detergent additives.

[0011] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: a washing machine dispensing device, comprising,

[0012] A detergent dispenser, wherein the bottom wall of the detergent dispenser has an opening.

[0013] A bracket assembly, installed at the opening, is used to open or close the opening.

[0014] A magnetic attachment assembly is used to magnetically engage the bracket assembly with the bottom wall of the detergent dispenser to close the opening.

[0015] Furthermore, the support assembly includes,

[0016] The first support is located on the bottom wall of the detergent dispenser.

[0017] The second bracket, located below the first bracket and at least partially below the horizontal plane of the bottom wall of the detergent dispenser, is used to open or close the opening.

[0018] The connectors are connected to the first and second supports respectively, and are used to guide the second support to move up and down.

[0019] Preferably, the connector is movably connected to the first bracket and / or the second bracket.

[0020] Furthermore, the magnetic attraction component includes,

[0021] The first component is mounted on the first bracket or on the bottom wall of the detergent dispenser.

[0022] The second component is mounted on the second bracket.

[0023] The first and second components are magnetically attracted to each other, providing a force that allows the second bracket to adhere to the bottom wall of the detergent dispenser and close the opening.

[0024] Furthermore, the first support is located at the opening, and there is a gap between it and the edge of the opening to form a liquid outlet.

[0025] The second bracket moves up and down relative to the first bracket and can detachably abut against the bottom wall of the detergent box at the edge of the opening.

[0026] Furthermore, the second bracket is provided with connection holes.

[0027] One end of the connector is connected to the first bracket, and the other end passes through the connecting hole and is movably connected to the second bracket.

[0028] The other end of the connector is provided with a blocking part to prevent the second bracket from detaching from the connector when it moves to the other end of the connector.

[0029] Furthermore, the first stent includes,

[0030] A support plate is provided at the opening, one end of the connector is connected to the support plate, and there is a gap between the edge of the support plate and the edge of the opening to form a liquid outlet.

[0031] The connecting arm is connected to the support plate at one end and to the bottom wall of the detergent box at the other end. The first bracket is fixed to the detergent box by the connecting arm.

[0032] Preferably, the first bracket is integrally formed with the bottom wall of the detergent box.

[0033] Furthermore, the second bracket includes a connecting portion and an abutting portion.

[0034] The connecting hole is located on the connecting part.

[0035] The abutting part is connected to the connecting part and is located on the outer periphery of the connecting part. The edge of the abutting part can abut against the bottom wall of the detergent box at the edge of the opening.

[0036] Preferably, the bottom wall of the detergent box extends downward along the edge of the opening to form a first baffle, and the lower end of the first baffle separably abuts against the edge of the abutment portion.

[0037] Preferably, the support plate extends downward from the edge to form a second baffle with a circumferential structure, and the support plate and the second baffle cooperate to form a sleeve structure with an opening at the lower end;

[0038] The connecting part protrudes upward relative to the abutting part, and the outer diameter of the connecting part is smaller than the outer diameter of the second baffle, so that the connecting part can move up and down within the sleeve formed by the cooperation of the support plate and the second baffle.

[0039] The connecting part protrudes upward relative to the abutting part, and moves up and down within the sleeve formed by the support plate and the second baffle. This allows the second baffle and the connecting part to protect the magnetic component, preventing additives entering the detergent dispenser from contacting it. Because additives contain many chemical components, prolonged contact or residue on the magnetic component can negatively impact its magnetic force.

[0040] It can also prevent additives from entering the connection between the first and second supports and the connector, and prevent additives from adhering to the connection and affecting the up and down movement of the second support, thereby affecting the use of the detergent box and the scheduled dispensing of additives.

[0041] Furthermore, the contact part is provided with a drain port for discharging the remaining additive mixture in the detergent box when the opening is closed, so as to avoid waste and pollution caused by long-term residue.

[0042] Furthermore, the attraction force between the first support and the second support is F1.

[0043] When the additive is added to the detergent box, the pressure on the second support is F2.

[0044] When water is introduced into the detergent box and additives are added, the pressure borne by the second support is F3.

[0045] The formula is F3+G>F1>F2+G, where G is the weight of the second support.

[0046] When the detergent dispenser is empty, the attraction between the first and second supports is greater than the weight of the second support, causing the second support to abut against the bottom wall of the detergent dispenser and close the opening.

[0047] When the detergent dispenser is filled with additives, the suction between the first and second supports is greater than the sum of the weight of the additives and the second support. The second support then comes into contact with the bottom wall of the detergent dispenser, closing the opening and thus storing the additives.

[0048] When water and additives mix in the detergent dispenser, the suction force between the first and second supports is less than the sum of the weight of the additive mixture and the second support. The second support moves downward, separates from the bottom wall of the detergent dispenser, opens the opening, and the fully dissolved additive mixture flows into the washing tub from the gap between the second support and the bottom wall of the detergent dispenser.

[0049] When water is added to the detergent dispenser, the water is added gradually, increasing the contact time between the water and the additives, which helps the additives dissolve and improves the washing effect.

[0050] As the water intake stops and the additive mixture continues to flow out, when the combined mass of the remaining small amount of additive mixture and the weight of the second support is less than the suction force between the first and second supports, the second support moves upward and comes into contact with the bottom wall of the detergent box, closing the opening. The remaining small amount of additive mixture is then discharged from the drain outlet, preventing waste and prolonged contamination of the detergent box.

[0051] A washing machine having a dispensing device as described above.

[0052] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0053] This invention provides a washing machine dispensing device, which connects a first bracket and a second bracket via a connector. By utilizing the attraction of a magnetic component, the second bracket can move up and down relative to the first bracket without detaching, thereby enabling the second bracket to detachably abut against the bottom wall of the detergent dispenser, thus realizing the function of scheduled dispensing of detergent additives.

[0054] The connecting part protrudes upward relative to the abutting part, and moves up and down within the sleeve formed by the support plate and the second baffle. This allows the second baffle and the connecting part to protect the magnetic component, preventing additives entering the detergent dispenser from contacting it. Because additives contain many chemical components, prolonged contact or residue on the magnetic component can negatively impact its magnetic force.

[0055] It can also prevent additives from entering the connection between the first and second supports and the connector, and prevent additives from adhering to the connection and affecting the up and down movement of the second support, thereby affecting the use of the detergent box and the scheduled dispensing of additives.

[0056] When water is added to the detergent dispenser, the water is added gradually, increasing the contact time between the water and the additives, which helps the additives dissolve and improves the washing effect.

[0057] The drain outlet design allows for the complete removal of additives from the detergent dispenser, preventing waste and contamination from prolonged residue.

[0058] The present invention provides a washing machine dispensing device that can realize the scheduled dispensing of solid or liquid additives, and has the characteristics of promoting additive dissolution, simple structure and convenient operation.

[0059] The present invention provides a washing machine with the above-mentioned dispensing device, which has the characteristics of improving washing effect, reducing cost and improving user experience.

[0069] like Figures 1 to 2 As shown, the present invention provides a washing machine dispensing device, including a water tank 12, a detergent box 1 inside the water tank 12, and a water inlet assembly 13 on the water tank 12; the bottom wall of the detergent box 1 has an opening 14, and a first baffle 8 extends downward along the edge of the opening 14; a bracket assembly is installed at the opening 14, the bracket assembly including a first bracket, a second bracket and a connector 4; the first bracket includes a support plate 2, a second baffle 7 and a connecting arm 3; the second bracket includes a connecting part 6 and an abutting part 15, the abutting part 15 is provided with a drain port 11; the connector 4 is provided with a blocking part 5; the magnetic suction assembly includes a first component 9 and a second component 10.

[0070] The present invention also provides a washing machine having the above-described dispensing device.

[0071] As one implementation scheme, the present invention provides a washing machine dispensing device, such as... Figures 1 to 2 As shown, it includes a water tank 12, inside which is a pull-out detergent box 1, and a water inlet assembly 13 is provided above the water tank 12.

[0072] The bottom wall of the detergent dispenser 1 has an opening 14, and the bottom wall of the detergent dispenser 1 extends downward along the edge of the opening 14 to form a first baffle 8. The opening 14 can be circular or other shapes.

[0073] It also includes a bracket assembly, which is installed at the opening 14 for opening or closing the opening 14.

[0074] The support assembly includes a first support, a second support, and a connector 4.

[0075] The first support is located on the bottom wall of the detergent box 1.

[0076] The second bracket is located below the first bracket, at least partially below the horizontal plane where the bottom wall of the detergent box 1 is located, and is used to open or close the opening 14.

[0077] Connector 4 is connected to the first bracket and the second bracket respectively, and is used to guide the second bracket to move up and down.

[0078] The second bracket moves up and down relative to the first bracket and can detachably abut against the bottom wall of the detergent box 1 at the edge of the opening 14.

[0079] Specifically, the first bracket is integrally formed with the bottom wall of the detergent box 1, including a support plate 2 and a connecting arm 3.

[0080] The support plate 2 is located at the opening 14, and there is a gap between the edge of the support plate 2 and the edge of the opening 14 to form a liquid outlet.

[0081] One end of the connecting arm 3 is connected to the support plate 2, and the other end is connected to the bottom wall of the detergent box 1. The first bracket is fixed to the detergent box 1 by the connecting arm 3.

[0082] The second support includes a connecting part 6 and an abutting part 15.

[0083] The connecting part 6 is provided with a connecting hole.

[0084] The abutting part 15 is connected to the connecting part 6 and is provided on the outer periphery of the connecting part 6. The edge of the abutting part 15 abuts detachably with the lower end of the first baffle 8.

[0085] One end of the connector 4 is connected to the support plate 2 of the first bracket, and the other end passes through the connecting hole and is movably connected to the connecting part 6 of the second bracket.

[0086] The other end of the connector 4 is provided with a blocking part 5 to prevent the second bracket from detaching from the connector 4 when it moves to the other end of the connector 4.

[0087] The support plate 2 extends downward from the edge to form a second baffle 7 with a circumferential structure. The support plate 2 and the second baffle 7 cooperate to form a sleeve structure with an opening at the lower end.

[0088] The connecting part 6 protrudes upward relative to the abutting part 15. The outer diameter of the connecting part 6 is smaller than the outer diameter of the second baffle 7, so that the connecting part 6 can move up and down within the sleeve formed by the cooperation of the support plate 2 and the second baffle 7.

[0089] The connecting part 6 protrudes upward relative to the abutting part 15, and moves up and down within the sleeve formed by the support plate 2 and the second baffle 7. This cooperation between the second baffle 7 and the connecting part 6 protects the magnetic component, preventing additives entering the detergent dispenser 1 from contacting it. Because additives contain many chemical components, prolonged contact or residue on the magnetic component may negatively affect its magnetic attraction.

[0090] It can also prevent additives from entering the connection between the first and second supports and the connector 4, and prevent additives from adhering to the connection and affecting the up and down movement of the second support, thereby affecting the use of the detergent box 1 and the scheduled dispensing of additives.

[0091] The contact part 15 is also provided with a drain port 11, which is used to drain the remaining additive mixture in the detergent box 1 when the opening 14 is closed, so as to avoid waste and pollution caused by long-term residue.

[0092] It also includes a magnetic attachment assembly for attaching the bracket assembly to the bottom wall of the detergent dispenser 1 to close the opening 14.

[0093] The magnetic attraction assembly includes a first component 9 and a second component 10.

[0094] The first component 9 is mounted on the first bracket and is located at the bottom of the support plate 2.

[0095] The second component 10 is mounted on the second bracket and is located at the bottom of the connecting part 6.

[0096] The first component 9 and the second component 10 are magnetically attracted to each other, which provides the force for the second bracket to attract and close the opening 14 with the bottom wall of the detergent box 1.

[0097] Specifically, the first component 9 and the second component 10 are opposite magnets. By using the attraction between opposite magnets, the first support and the second support are attracted together, thereby causing the edge of the abutment 15 to abut against the lower end of the first baffle 8 and closing the opening 14.

[0098] The attraction force between the first and second supports is F1.

[0099] When the additive is added to the detergent dispenser 1, the pressure on the second support is F2.

[0100] When water is added to detergent dispenser 1 and additives are added, the pressure on the second support is F3.

[0101] F3+G>F1>F2+G, where G is the weight of the second support.

[0102] In this solution, when the detergent box 1 is empty, the attraction force between the first bracket and the second bracket is greater than the weight of the second bracket, and the edge of the abutting part 15 of the second bracket abuts against the lower end of the first baffle 8, closing the opening 14.

[0103] When a user wants to perform laundry, they first pull the detergent box 1 out of the water box 12 and add an appropriate amount of additive. At this time, the suction between the first bracket and the second bracket is greater than the sum of the weight of the additive and the second bracket. The edge of the abutting part 15 of the second bracket abuts against the lower end of the first baffle 8, closing the opening 14 and serving to store the additive.

[0104] Push the detergent dispenser 1 into the water tank 12, select the appropriate washing program, and the washing machine will start. Water will enter the detergent dispenser 1 through the water inlet assembly 13. Since the water is added gradually, the contact time between the water and the additives is increased, which is beneficial for the dissolution of the additives and improves the washing effect.

[0105] As water is added, the additive and water are fully mixed, and the mass of the additive mixture gradually increases. When the suction force between the first support and the second support is less than the sum of the weight of the additive mixture and the second support, the second support moves downward, the edge of the contact part 15 separates from the lower end of the first baffle 8, and the opening 14 is opened. The fully dissolved additive mixture flows into the washing tub from the gap between the edge of the contact part 15 and the first baffle 8.

[0106] As the water supply stops and the additive mixture continues to flow out, when the sum of the mass of the remaining small amount of additive mixture and the weight of the second support is less than the suction force between the first and second supports, the second support moves upward, and the edge of the contact part 15 abuts against the lower end of the first baffle 8 again, closing the opening 14. The remaining small amount of additive mixture is discharged from the drain port 11, avoiding waste and long-term residue contamination of the detergent box 1.

[0107] Furthermore, the additives in this solution can be either solid or liquid, meeting the needs of various additive applications.

[0108] As one implementation, the present invention provides a washing machine dispensing device, wherein the first bracket may also be a mounting component installed at the opening 14 on the bottom wall of the detergent box 1.

[0109] As one implementation, the present invention provides a washing machine dispensing device, wherein the connecting part 6 may be on the same horizontal plane as the abutting part 15; the abutting part 15 may also be inclined downward from the connecting part 6 toward the first baffle 8 to facilitate the outflow of the additive mixture, etc.

[0110] As one implementation scheme, the present invention provides a washing machine dispensing device, wherein the connector 4 can be a pin or other connecting device, as long as the first bracket and the second bracket are connected, and the second bracket can move up and down relative to the first bracket without detaching.

[0111] As one implementation, the present invention provides a washing machine dispensing device. The first component 9 and the second component 10 can also be a combination of magnets and iron, etc., as long as they can provide the attraction force between the first bracket and the second bracket. No specific limitation is made in this regard.

[0112] The installation positions of the first component 9 and the second component 10 can be adjusted according to the actual structure. For example, the first component 9 can also be installed on the bottom wall of the detergent box 1.

[0113] As one implementation, the present invention provides a washing machine dispensing device, wherein the bottom wall of the detergent box 1 is not provided with a first baffle 8, and the edge of the abutting part 15 of the second bracket directly abuts against the bottom wall of the detergent box 1 at the edge of the opening 14, thereby closing the opening 14.

[0114] As one embodiment, the present invention provides a washing machine having the above-described dispensing device.

[0115] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention.
