Description

Technical Field

[0001] This application belongs to the field of cleaning equipment technology, and in particular relates to an automatic dispensing device and cleaning equipment. Background Technology

[0002] The automatic dispensing device of the washing machine can accurately dispense cleaning liquid. The automatic dispensing device includes a pump body, and the discharge channel of the pump body is connected to the dispensing pipe. The cleaning liquid discharged from the dispensing pipe can enter the mixing chamber of the automatic dispensing device. The water flow into the mixing chamber can carry away the cleaning liquid in the mixing chamber and flow into the drum of the washing machine.

[0003] When the washing machine enters the rinsing stage, the pump does not work, so there is no need to add cleaning solution to the mixing chamber; however, when the pump is not working, the cleaning solution in the dispensing pipe may also flow into the mixing chamber, resulting in incomplete rinsing.

[0053] This application provides an automatic dispensing device 100, applied to a cleaning device 1. The cleaning device 1 can be a laundry processing device, or other cleaning devices 1 that require automatic dispensing of cleaning solution, such as a base station for a robot vacuum cleaner. When the automatic dispensing device 100 is applied to a laundry processing device, the laundry processing device can be a washing machine or a washer-dryer combo. The following description mainly uses the application of the automatic dispensing device 100 to a washing machine as an example to further detail the automatic dispensing device 100 provided in this application embodiment.

[0054] Please see Figure 1 The garment handling equipment includes a box body 10 and a drive assembly 20, the drive assembly 20 being mounted on the box body 10. See also... Figure 2 The drive assembly 20 includes a drive body 21 and a dispensing pipe 22, with the discharge channel of the drive body 21 connected to the dispensing pipe 22. When the drive body 21 is activated, it can draw cleaning fluid (which may be a cleaning agent, fabric softener, disinfectant, etc.) into itself and discharge the cleaning fluid through the discharge channel and then through the dispensing pipe 22.

[0055] Please see Figure 2 The main body 10 of the box has a mixing chamber 11, and the dispensing pipe 22 is connected to the mixing chamber 11. When the drive body 21 moves, the cleaning fluid can be discharged into the mixing chamber 11 through the dispensing pipe 22. Please refer to Figure 1 and Figure 2A water inlet pipe interface 131 is provided on the mixing chamber 11, and a drain pipe interface 132 connected to the mixing chamber 11 is provided on the main body 10. The water inlet pipe interface 131 is used to connect to the water inlet pipe, and the drain pipe interface 132 is used to connect to the drum of the washing machine through the discharge pipe. External water source can enter the mixing chamber 11 through the water inlet pipe and the water inlet pipe interface 131. The water entering the mixing chamber 11 flushes the cleaning liquid in the mixing chamber 11, and the water mixed with the cleaning liquid can flow into the drum through the drain pipe interface 132 and the discharge pipe.

[0056] In some examples, the delivery tube 22 may be integrally formed on the housing of the drive body 21.

[0057] See some examples. Figure 2 and Figure 3 The main body 10 includes a dispensing box 12 and a drawer structure 13. The dispensing box 12 is disposed within the drawer structure 13. Part or all of the space between the inner side of the drawer structure 13 and the outer side of the dispensing box 12 can be used to form a mixing chamber 11. The dispensing box 12 is used to hold cleaning fluid, meaning the user can dispense the cleaning fluid into the dispensing box 12. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 The drive assembly 20 also includes a suction pipe 23, which connects the dispensing box 12 and the entry channel of the drive body 21. When the drive body 21 is activated, the cleaning fluid in the dispensing box 12 can be drawn into the drive body 21 through the suction pipe 23.

[0058] In the embodiments of this application, please refer to Figure 2 and Figure 3 The automatic dispensing device 100 also includes a valve body structure 30, please refer to [link / reference]. Figure 3 The valve body structure 30 can be mounted on the box body 10, or, please refer to [link / reference]. Figure 2 Alternatively, the valve body structure 30 can be installed on the dispensing pipe 22. The valve body structure 30 is used to change the connection state between the dispensing pipe 22 and the mixing chamber 11.

[0059] Please see Figure 4 This diagram illustrates the dispensing tube 22 and the box body 10 without the valve structure 30 installed. After the automatic dispensing device 100 has finished dispensing, cleaning fluid will be stored in the dispensing tube 22. Please refer to [link / reference]. Figure 4This illustrates the residual cleaning solution 2 stored in the dispensing pipe 22. When rinsing clothes, external water can enter the mixing chamber 11 through the inlet pipe and inlet pipe interface 131. The water entering the mixing chamber 11 flows to the drum through the drain pipe interface 132 and the discharge pipe. During rinsing, the water flowing into the drum should be clean water. However, because the dispensing pipe 22 stores residual cleaning solution 2, the clean water entering the mixing chamber 11 will enter the dispensing pipe 22 through the opening, rinsing or soaking the cleaning solution 2 in the dispensing pipe 22. This mixture then flows out from the opening of the dispensing pipe 22 back into the mixing chamber 11, resulting in cleaning solution residue remaining on the clothes after rinsing. This means the clothes are not properly rinsed, and improperly rinsed clothes may cause skin allergies or other health problems.

[0060] Please see Figure 2 and Figure 3 In this embodiment of the application, a valve body structure 30 is also provided. The valve body structure 30 changes the conduction state between the dispensing pipe 22 and the mixing chamber 11. That is, the valve body structure 30 can realize the conduction state between the dispensing pipe 22 and the mixing chamber 11 when needed, and block the connection state between the dispensing pipe 22 and the mixing chamber 11 when not needed.

[0061] For example, in one embodiment, the valve body structure 30 is a controllable switch valve body; for instance, the valve body structure 30 can be configured as a solenoid valve. When cleaning fluid needs to be supplied to the mixing chamber 11, the valve body structure 30 is opened to connect the dispensing pipe 22 to the mixing chamber 11. When the drive body 21 is activated, the cleaning fluid in the dispensing box 12 can be dispensed into the mixing chamber 11. When rinsing clothes inside the drum, the valve body structure 30 is closed. At this time, the valve body structure 30 keeps the dispensing pipe 22 and the mixing chamber 11 disconnected, preventing the water in the mixing chamber 11 from flushing the cleaning fluid in the dispensing pipe 22. In other words, the water entering the mixing chamber 11 cannot flush the cleaning fluid. Figure 5 The residual cleaning fluid 2 in the middle inlet pipe 22 is flushed out, and at the same time, the residual cleaning fluid 2 in the inlet pipe 22 is prevented from flowing into the mixing chamber 11.

[0062] For example, in some examples, the valve body structure 30 is a one-way valve, and the one-way conduction direction of the valve body structure 30 is from the dispensing pipe 22 to the mixing chamber 11. When cleaning fluid needs to be supplied to the mixing chamber 11, the drive body 21 can dispense the cleaning fluid in the dispensing box 12 into the mixing chamber 11. When rinsing the clothes in the drum, because the valve body structure 30 is a one-way valve, the water in the mixing chamber 11 cannot flow into the dispensing pipe 22, that is, the water in the mixing chamber 11 cannot flush the cleaning fluid in the dispensing pipe 22. That is, in this example, by setting the valve body structure 30 as a one-way valve, the conduction state between the dispensing pipe 22 and the mixing chamber 11 is changed.

[0063] It is worth noting that a certain opening pressure is usually required for a one-way valve to conduct in the forward direction. Alternatively, it can be understood that the valve body structure 30 provided in this embodiment can be set as a one-way valve with a certain opening pressure. When the driving body 21 is activated, the driving body 21 drives the cleaning fluid to flow, so that the cleaning fluid has a certain pressure sufficient to open the valve body structure 30. When the driving body 21 is not activated, there is not enough pressure for the cleaning fluid stored in the delivery pipe 22 to open the valve body structure 30, so that the cleaning fluid stored in the delivery pipe 22 will not slowly overflow into the mixing chamber 11 through the valve body structure 30.

[0064] See some examples. Figure 2 The valve body structure 30 is installed on the delivery pipe 22, and the valve body structure 30 is located at the end of the delivery pipe 22 (that is, the valve body structure 30 is located at the end of the delivery pipe 22 away from the drive body 21).

[0065] See some examples. Figure 2 The valve body structure 30 is mounted on the dispensing pipe 22, and the dispensing pipe 22 passes through the box body 10 and extends into the mixing chamber 11; or, in other examples, one end of the dispensing pipe 22 may be connected to the box body 10 and not extend into the mixing chamber 11.

[0066] See some examples. Figure 3 The valve body structure 30 is installed on the box body 10, and one end of the dispensing pipe 22 is connected to the box body 10 but does not extend into the mixing chamber 11.

[0067] In this embodiment of the application, by setting the automatic dispensing device 100 to include a valve body structure 30 for changing the conduction state between the dispensing pipe 22 and the mixing chamber 11, it is possible to ensure that when the washing machine is rinsing, the water entering the mixing chamber 11 cannot rinse or soak the cleaning liquid remaining in the dispensing pipe 22, thereby avoiding the situation in the prior art where the cleaning liquid remaining in the dispensing pipe during the washing machine rinsing is carried into the mixing chamber 11 and then into the drum, resulting in incomplete rinsing.

[0068] Please see Figures 6-10 , Figure 6 This is a schematic diagram of the structure of the automatic dispensing device 100 provided in some embodiments of this application. Figure 7 This is a cross-sectional schematic diagram of an automatic dispensing device 100 provided in some embodiments of this application. Figure 8 for Figure 7 A magnified view of a portion of point A in the middle. Figure 9 This is a partial exploded view of the box body 10 and valve body structure 30 provided in some embodiments of this application. Figure 10 An exploded view of an automatic dispensing device 100 provided in some embodiments of this application.

[0069] In some embodiments, see Figure 8 and Figure 9 The main body 10 of the box is provided with a dispensing port 1131 that communicates with the mixing chamber 11. Please refer to [link / reference]. Figure 8 The dispensing pipe 22 is connected to the dispensing port 1131, and the valve body structure 30 is installed on the box body 10. The valve body structure 30 is used to change the opening and closing state of the dispensing port 1131.

[0070] In this embodiment, the valve body structure 30 can be configured as a one-way valve. Specifically, when the driving body 21 is activated, it drives the cleaning fluid to flow, giving the cleaning fluid sufficient pressure to open the inlet 1131 of the valve body structure 30, allowing the cleaning fluid to flow into the mixing chamber 11 through the inlet 1131. When the driving body 21 is not activated, there is insufficient pressure for the cleaning fluid stored in the inlet pipe 22 to open the inlet 1131 of the valve body structure 30, and the cleaning fluid stored in the inlet pipe 22 will not overflow into the mixing chamber 11 through the valve body structure 30. Since the one-way flow direction of the valve body structure 30 is from the inlet pipe 22 to the mixing chamber 11, when rinsing the clothes in the drum, the water in the mixing chamber 11 cannot flow into the inlet pipe 22, that is, the water in the mixing chamber 11 cannot flush the cleaning fluid in the inlet pipe 22.

[0071] In this embodiment, the valve body structure 30 can also be configured as a solenoid valve, which can be controlled to open or close the inlet 1131. When the drive body 21 is activated, it simultaneously controls the valve body structure 30 to open the inlet 1131, allowing the drive body 21 to drive the cleaning fluid to flow into the mixing chamber 11 through the inlet 1131. When the drive body 21 is not activated, it can simultaneously control the valve body structure 30 to close the inlet 1131, preventing the cleaning fluid stored in the inlet pipe 22 from overflowing into the mixing chamber 11 through the valve body structure 30. When rinsing clothes in the drum, the water in the mixing chamber 11 cannot flow into the inlet pipe 22, meaning the water in the mixing chamber 11 cannot flush the cleaning fluid in the inlet pipe 22.

[0072] In some examples, the valve body structure 30 may be detachably connected to the housing body 10 to facilitate the disassembly and assembly of the valve body structure 30 for maintenance or replacement.

[0073] In some examples, the valve body structure 30 can be configured as a diaphragm check valve, where a resilient diaphragm (such as silicone) controls the flow direction; alternatively, the valve body structure 30 can be configured as a spring-loaded check valve. Typically, a spring-loaded check valve includes a valve body, a valve core, and a spring. If the fluid pressure exceeds the spring preload, the valve core can be pushed open to achieve unidirectional flow. Of course, the valve body structure 30 is not limited to diaphragm or spring-loaded check valves; other check valves with unidirectional flow can also be used.

[0074] In this embodiment, the valve body structure 30 is fixed on the box body 10 to facilitate the installation of the valve body structure 30.

[0075] In some embodiments, see Figure 9 The valve body structure 30 includes a valve connection part 31 and a valve deformation part 32. The valve connection part 31 is connected to the valve deformation part 32, and the valve deformation part 32 is made of an elastic deformation material. The valve connection part 31 is installed on the box body 10, and the valve deformation part 32 is located in the mixing chamber 11 and covers the dispensing port 1131.

[0076] See some examples. Figure 9 An installation hole 1132 is provided on the box body 10, and the valve connection part 31 is inserted and fixed on the box body 10.

[0077] In some examples, the valve connection 31 may be bonded, threaded, or snap-fitted onto the box body 10.

[0078] In some examples, the valve connection 31 may be made of an elastic material; please refer to [reference needed]. Figure 9 An annular protrusion 311 is formed on the outer peripheral side of the valve connection part 31. The annular protrusion 311 undergoes elastic deformation to allow the valve connection part 31 to be inserted into the mounting hole 1132. The annular protrusion 311 and the valve deformation part 32 are located on opposite sides of the box body 10, so that the valve body structure 30 is limited on the box body 10.

[0079] In this embodiment, when the driving body 21 is activated, the driving body 21 drives the cleaning fluid to flow, so that the cleaning fluid has a certain pressure and squeezes the valve deformation part 32 to make the valve deformation part 32 elastically deform to open the inlet 1131, so that the cleaning fluid flows into the mixing chamber 11 through the inlet 1131.

[0080] In some examples, the valve body structure 30 can be made of rubber material.

[0081] In some examples, the valve body structure 30 can be configured as a one-piece molded structure.

[0082] In this embodiment, by providing the valve body structure 30 with a valve connection part 31 and a valve deformation part 32, the valve body structure 30 is simple in structure and low in cost.

[0083] In some embodiments, the number of dispensing ports 1131 is at least one, and when there are two or more dispensing ports 1131, each dispensing port 1131 is spaced apart along the circumferential direction of the valve connection portion 31.

[0084] When there is only one inlet 1131, the valve deformation part 32 can be set to be annular, or the shape of the valve deformation part 32 can be set to be the same as or approximately the same as the shape of the inlet 1131, and the valve deformation part 32 covers the inlet 1131.

[0085] When there are two or more dispensing ports 1131, each dispensing port 1131 is spaced apart along the circumferential direction of the valve connection part 31. In this case, the valve deformation part 32 can be set to be annular, and one valve deformation part 32 can cover each dispensing port 1131; or, there can be two or more valve deformation parts 32, the number of valve deformation parts 32 is the same as the number of dispensing ports 1131, and the valve deformation parts 32 correspond one-to-one with the dispensing ports 1131, that is, the valve deformation part 32 can cover the corresponding dispensing port 1131.

[0086] See some examples. Figure 9 The number of dispensing ports 1131 is two, and the two dispensing ports 1131 are arc-shaped and arranged opposite each other vertically; or, the number of dispensing ports 1131 can be three or more, and each dispensing port 1131 is arc-shaped and spaced apart along the circumferential direction of the valve connection part 31.

[0087] In this embodiment, the number of inlet ports 1131 can be reasonably set to ensure that the cleaning fluid can flow through the inlet ports 1131 to the mixing chamber 11, while also matching the shape of the valve body structure 30.

[0088] In some embodiments, see Figure 8 The outer side of the box body 10 is provided with an installation cylinder 139. The interior of the installation cylinder 139 is connected to the dispensing port 1131. The dispensing tube 22 is inserted into the installation cylinder 139 and the two are sealed together.

[0089] In some examples, the mounting cylinder 139 can be inserted into the dispensing tube 22, or the dispensing tube 22 can be inserted into the mounting cylinder 139.

[0090] In some examples, the dispensing tube 22 and the mounting cylinder 139 can be configured to be sealed together by a sealing ring.

[0091] In some examples, the dispensing port 1131 may be set to surround the inner side of the mounting cylinder 139, that is, when the mounting cylinder 139 is projected in the direction of the dispensing port 1131, the dispensing port 1131 may be set to surround the inner side of the projection of the mounting cylinder 139; or, in other examples, a portion of the dispensing port 1131 may be set to surround the inner side of the mounting cylinder 139.

[0092] In this embodiment, an installation cylinder 139 is provided on the outer side of the box body 10 to facilitate the installation of the dispensing tube 22 on the installation cylinder 139.
