Description

Technical Field

[0001] This utility model relates to the field of automatic dispensing in washing machines, specifically an automatic dispensing box for washing machines. Background Technology

[0002] The automatic detergent dispenser inside the washing machine is an intelligent design. It is specifically designed to automatically add detergent according to the needs of the washing program. When in use, the user only needs to pour the detergent into the corresponding compartment in advance, and after setting the washing program, the washing machine will automatically add the appropriate amount of detergent at the appropriate time. This design not only improves washing efficiency, but also avoids the problem of adding too much or too little detergent when adding detergent manually. It is a major highlight of modern washing machines.

[0003] Chinese Patent Publication No. CN205313862U discloses an automatic dispensing system and a washing machine using the same, including a box, a liquid extraction device, and a liquid storage box. The liquid storage box has at least one solution receiving cavity. The liquid storage box is mounted on the box and can be pulled out relative to the box. The liquid storage box is provided with a solution outlet connection portion that can be connected to the liquid extraction device to extract the solution from the corresponding solution receiving cavity. This application can not only reduce the need for check valves and lower costs, but also avoid residual liquid leakage when the liquid storage box is separated, reduce solution waste, and improve the cleanliness and aesthetics of the washing machine.

[0004] When the aforementioned patented automatic dispensing system and the washing machine using it extract laundry detergent during use, the detergent comes into contact with the inlet pipe and the vertical pipe after extraction. The bends in the inlet pipe and the vertical pipe cause the detergent to adhere to the inside of the inlet pipe and the vertical pipe during extraction. Over time, this can cause blockages in the inlet pipe and the vertical pipe, making them difficult to clean. Furthermore, there is no restraining structure between the blockages in the inlet pipe and the vertical pipe. After the automatic dispensing box is connected to the washing machine, the vibrations generated during the operation of the washing machine can easily cause excess detergent to flow back into the washing machine. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic dispensing box for washing machines. When the automatic dispensing box is connected to the washing machine, the extension of the telescopic rod can push and adjust the lateral movement of the rubber pad. Combined with the extraction of the liquid inlet pipe, the washing liquid can be quantitatively extracted after passing through the extraction port and the flow chamber in sequence, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic dispensing box for a washing machine, comprising an upper outer shell and a lower outer shell welded to the lower end of the upper outer shell, including a telescopic rod welded and fixed to the washing machine outer shell, a fixing tube provided on the other side of the upper outer shell, an installation cavity provided through the interior of the fixing tube, an upper guide frame provided at the upper end of the interior of the upper outer shell, a flow cavity provided on the side of the installation cavity facing the upper guide frame, and a rubber pad provided on one side of the flow cavity.

[0007] Preferably, a lower guide frame is provided at the lower end of the interior of the lower housing, and the upper guide frame is located on one side of the liquid inlet pipe.

[0008] Preferably, the lower guide frame and the upper guide frame are welded and fixed together, and an extraction port is provided through the lower guide frame, which is located near the lower end of the lower outer shell.

[0009] Preferably, a pressing block is provided inside the mounting cavity, and the pressing block is welded and fixed to the rubber pad via a transmission rod.

[0010] Preferably, a spring is provided around the outside of the transmission rod.

[0011] Preferably, the flow cavity extends through and to both sides of the upper guide frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In this invention, when connecting the automatic dispensing box of a washing machine to the washing machine, the connection is completed after the inlet pipe and the pressing block connected to the surface of the washing machine are inserted into the mounting cavity inside the fixing tube. The connection process is simple, requiring only that the inlet pipe is sealed and connected to the mounting cavity. Before the laundry detergent is drawn from the lower guide frame, one end of the inlet pipe is positioned before the suction force is generated by the internal extraction device of the washing machine. The extension and retraction of the telescopic rod can push the rubber pad, exposing the flow cavity, so that the laundry detergent stored at the lower end of the sealing cover can be drawn from the flow cavity. This simplifies the structure for extracting laundry detergent. The inlet pipe is exposed to the outside for easy cleaning. When not extracting, the spring's elasticity will actively cause the rubber pad to restrict the flow cavity, preventing excess laundry detergent from leaking out from the flow cavity.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, an automatic dispensing box for a washing machine in this embodiment includes an upper outer shell 1, a lower outer shell 3 at the lower end of the upper outer shell 1, and the upper end of the lower outer shell 3 is welded and fixed to the lower end of the upper outer shell 1. A sealing cover 2 is provided at the upper end of the outer shell 1, and the sealing cover 2 is sealed to the upper outer shell 1. Removing the sealing cover 2 can expose the area covered by the upper outer shell 1 and the lower outer shell 3, which is convenient for pre-pouring the laundry detergent into the interior and for subsequent extraction of the laundry detergent.

[0022] In order to facilitate the removal and installation of the upper outer shell 1 and the lower outer shell 3, a connecting frame 6 is provided on one side of the upper outer shell 1 and the lower outer shell 3, and the connecting frame 6 is welded and fixed to the upper outer shell 1 and the lower outer shell 3. The protruding connecting frame 6 makes it easy to remove and install the automatic dispensing box of the washing machine.

[0023] In addition, a fixing tube 4 is provided on the other side of the upper outer shell 1. An installation cavity 5 is provided inside the fixing tube 4. During the extraction process, the laundry detergent will be discharged from the installation cavity 5. The side is higher than the level of the laundry detergent stored inside the upper outer shell 1 and the lower outer shell 3, which can prevent the laundry detergent from leaking when the liquid inlet pipe 10 inside the installation cavity 5 is removed.

[0024] To prevent the detergent from being drawn out, a lower guide frame 9 is provided at the lower end of the lower outer shell 3, and an upper guide frame 11 is provided at the upper end of the upper outer shell 1. The upper guide frame 11 is located on one side of the liquid inlet pipe 10. When the liquid inlet pipe 10 draws out the detergent, the detergent will be transported along the lower guide frame 9 and the upper guide frame 11 and eventually flow into the fixed pipe 4.

[0025] To improve the stability of the connection between the upper outer shell 1 and the lower outer shell 3, the lower guide frame 9 is welded and fixed to the upper guide frame 11. An extraction port 8 is provided through the lower guide frame 9, located near the lower end of the lower outer shell 3. Extraction from the fixed tube 4 position allows laundry detergent to flow from the extraction port 8 into the lower guide frame 9 and the upper guide frame 11, facilitating the precise dispensing of laundry detergent.

[0026] When not dispensing laundry detergent, such as Figure 3 and Figure 4 As shown, to prevent laundry detergent from actively flowing into the mounting cavity 5, a flow cavity 17 is provided on the side of the mounting cavity 5 facing the upper guide frame 11. The flow cavity 17 extends through and to both sides of the upper guide frame 11. A rubber pad 12 is provided on one side of the flow cavity 17. The diameter of the rubber pad 12 is larger than the diameter of the flow cavity 17. By actively adhering to one side of the flow cavity 17, the discharge of laundry detergent can be restricted. By adhering the rubber pad 12 to the upper guide frame 11, the outflow of laundry detergent can be restricted.

[0027] The installation cavity 5 is equipped with a pressing block 15. The pressing block 15 is welded and fixed to the rubber pad 12 through the transmission rod 13. By pushing the pressing block 15, the transmission rod 13 can drive the rubber pad 12 to adjust its position. The adjustment of the position of the rubber pad 12 can realize the extraction of laundry detergent.

[0028] In addition, after the pressing block 15 is not pushed, in order to reset the rubber pad 12 and make it stick tightly to the upper guide frame 11, a spring 14 is provided around the outside of the transmission rod 13, and the two ends of the spring 14 are welded and fixed to the upper guide frame 11 and the pressing block 15 respectively. The spring 14 can actively reset the pressing block 15 and the rubber pad 12 through its elasticity, and reset the rubber pad 12 to stick tightly to and restrict the flow cavity 17.

[0029] To facilitate the removal of the automatic dispensing box from the washing machine, an inlet pipe 10 is provided on one side of the fixed pipe 4. A telescopic rod 16 is provided inside the inlet pipe 10, and one end of both the telescopic rod 16 and the inlet pipe 10 are connected to the washing machine. The telescopic rod 16 is welded and fixed to the outer shell of the washing machine. The telescopic rod 16 is sealed and waterproof and will not be corroded by the laundry detergent. Referring to Chinese Patent No. CN208106906U, a waterproof electric telescopic rod is disclosed. Therefore, the waterproof function of the electric telescopic rod is prior art and will not be described in detail in this application. The outside of the inlet pipe 10 is sealed to the inside of the mounting cavity 5, and one end of the inlet pipe 10 is sealed to the washing machine.

[0030] To facilitate the extraction of laundry detergent and prevent it from accumulating between the upper outer shell 1 and the lower outer shell 3 and becoming difficult to extract, a slope 7 is provided on one side of the extraction port 8, and the slope 7 is recessed inside the lower outer shell 3. The recessed lower outer shell 3 facilitates the extraction of laundry detergent.

[0031] Working principle: When using the automatic dispensing box and transferring laundry detergent, open the sealing cover 2 and pre-pour the laundry detergent between the upper outer shell 1 and the lower outer shell 3. The inlet pipe 10 and the telescopic rod 16 connected to the washing machine are inserted into the mounting cavity 5 inside the fixed pipe 4. When extracting laundry detergent, the telescopic rod 16 is activated. The extension of the telescopic rod 16 is driven by the pressing block 15 and the transmission rod 13 to move the rubber pad 12 laterally. The telescopic rod 16 generates suction, which causes the pre-poured laundry detergent to flow from the extraction port 8 into the cavity formed by the lower guide frame 9 and the upper guide frame 11. Finally, it passes through the exposed flow cavity 17 and is transferred to the washing machine through the telescopic rod 16. The extension time of the telescopic rod 16 can accommodate different amounts of laundry detergent. After the telescopic rod 16 stops pressing and resets, the elasticity of the spring 14 allows the rubber pad 12 to be tightly pressed against one side of the flow cavity 17.
