Detailed Implementation

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] See appendix Figure 1-5This application provides a dishwasher with an automatic liquid dispensing module, comprising an inner tank 1, a liquid storage box 2, a pump body 3, and a liquid dispenser 4. The inner tank 1 has a liquid outlet 5 on its side wall, and a first tube 6 is provided around the liquid outlet 5 on the outer side of the inner tank 1. The liquid dispenser 4 has a second tube 7 that is inserted into the first tube 6. A one-way valve is provided inside the second tube 7, with the flow direction of the one-way valve being from the second tube 7 to the liquid outlet 5. The output end of the pump body 3 is connected to the second tube 7, and the input end of the pump body 3 is connected to the liquid storage box 2. The one-way valve is positioned near... The near-outlet 5 allows for quick closure of the second pipe 7 after the pump 3 stops working, effectively cutting off the flow of dishwasher-specific liquid at close range. This prevents excessive dishwasher-specific liquid from leaking out and causing residue buildup after the dishwasher stops operating. The liquid storage box 2 is equipped with a vent structure 8 and a liquid level monitoring device. The liquid level monitoring device monitors the liquid level in the storage box 2 and issues an alarm based on the liquid level. This alarm can be an audible alarm or a visual alarm, serving as a reminder to the user to replenish the dishwasher-specific liquid in a timely manner.

[0019] The liquid storage box 2 is fixed to the bottom wall of the inner liner 1. The upper end of the liquid storage box 2 has a liquid replenishment port 9. The bottom wall of the inner liner 1 has a connector 10 that connects to the liquid replenishment port 9. The connector 10 is provided with an openable sealing cover 11. After the user opens the sealing cover 11, he can pour dishwasher-specific liquid onto the connector 10 to replenish the liquid storage box.

[0020] See appendix Figure 5 A first sealing ring 12 is provided between the liquid inlet 9 and the connector 10, and a second sealing ring 13 is provided between the sealing cover 11 and the connector 10. The first and second sealing rings can improve the sealing performance and avoid problems such as water leakage and liquid leakage.

[0021] The fluid inlet 9 is provided with a screw-on position 14, and the sealing cover 11 is provided with a retaining rib 15 that cooperates with the screw-on position 14. The user can remove the sealing cover by forcefully turning the sealing cover 11 to disengage the retaining rib 15 from the screw-on position 14. When installing the sealing cover, first put the sealing cover 11 on the connector 10, and then press down and rotate the sealing cover to make the retaining rib 15 engage with the screw-on position 14.

[0022] See appendix Figure 4 The liquid level monitoring device includes a float 16 and a PCB board 17. The float 16 is located inside the liquid storage box 2, and the PCB board 17 is located outside the liquid storage box 2. A reed switch 18 is provided on the PCB board 17, and a magnet is provided inside the float 16. When the dishwasher liquid inside the liquid storage box 2 is full, the float rises and triggers the reed switch 18 to close. When the dishwasher liquid is insufficient, the float 16 descends with the dishwasher liquid. After leaving the range of the triggering reed switch, the reed switch 18 opens, and a low liquid alarm is issued.

[0023] The liquid storage box 2 has a recessed area 19, and the float 16 is located in the recessed area 19. The liquid storage box 2 has a limiting structure 20 to prevent the float 16 from leaving the recessed area 19. The reed switch 18 is located near the upper part of the recessed area 19. The recessed area 19 is the lowest horizontal position of the liquid storage box 2. The dishwasher liquid will gradually flow into the recessed area 19 under the action of gravity. Setting the float 16 in the recessed area 19 can better monitor the liquid level. The limiting structure 20 is specifically a limiting post, which is set towards the opening of the recessed area 19 to hold the float 16 and prevent the float from leaving the recessed area 19.

[0024] The one-way valve includes a bracket 21, a movable plug 22, and a spring 23. The movable plug 22 is slidably connected to the bracket 21. Specifically, the bracket 21 has a shaft hole, and the movable plug 22 has a shaft 221 that is movably connected to the shaft hole. The spring 23 is sleeved on the shaft 221. The bracket 21 has a sealing end 211, and the movable plug 22 can be connected to the sealing end 211 to close the second tube 7. The spring 23 abuts against the bracket 21 and the movable plug 22 respectively to keep the movable plug 22 connected to the sealing end 211. When the pump 3 works to output dishwasher-specific liquid to the second tube 7, the pump pressure can open the movable plug 22. At this time, the spring 23 is in a compressed state. When the pump 3 stops working, the spring 23 restores its deformation and pushes the movable plug to connect with the sealing end 211 to close the second tube again.

[0025] The inner liner 1 has an outwardly protruding liquid receiving groove 24 with an open top on its outer side. The liquid receiving groove 24 is connected to the inside of the inner liner 1 and is located below the liquid dispenser 4. When the liquid dispenser is damaged or the seal is broken, dishwasher detergent drips from the dispenser. The liquid receiving groove 24 can catch the dishwasher detergent and guide it into the inner liner 1. Specifically, the bottom of the side wall of the inner liner 1 has a drain outlet 25, which is connected to the liquid receiving groove 24. When the user finds dishwasher detergent flowing out of the drain outlet 25, it can be determined that the liquid dispenser is damaged or malfunctioning, and repairs can be reported in time. At the same time, it can prevent dishwasher detergent from dripping directly onto the bottom shell of the dishwasher and accidentally triggering the leakage alarm on the bottom shell.

[0026] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
