Description

Technical Field

[0001] The utility model relates to the field of washing machine equipment, in particular to a washing machine cleaning and disinfection device capable of quantitatively adding liquid. Background Art

[0002] The detergent used in the washing process of a traditional washing machine is placed separately from the washing machine. There is no detergent adding device on the washing machine, and the detergent cannot be added automatically. Each time you wash clothes, you need to open the lid of the laundry detergent bucket to add it manually, which is troublesome and cannot accurately add the amount, and the washing process of the washing machine cannot be fully automated. With the improvement of the automation of washing machines, most washing machines are designed so that the detergent box containing detergent or softener is connected to the water inlet pipe, and the detergent or softener in the detergent box is flushed into the washing bucket through the water inlet. However, this structure requires that the detergent or softener be placed in the detergent box before each washing, and the washing process is also not fully automated. In addition, when a large amount of laundry detergent or softener is poured out, but the amount of clothes to be washed is small, not only does it increase the difficulty of rinsing clothes and damage the clothes, but it also wastes a lot of water resources. If the amount poured out is too small at one time, the clothes will not be rinsed clean, and the purpose of washing cannot be achieved.

[0003] There are also technical solutions in the prior art for modifying the washing machine itself to meet the requirements of automatic quantitative liquid addition, but this modification requires structural improvements to the washing machine body, which not only invisibly increases the size of the washing machine itself, but also inevitably requires improvements to the internal flow channels and assembly forms, increasing the design cost and processing cost. Moreover, after the laundry detergent in the washing box is used up, this modification form still requires opening the washing machine again to add laundry detergent, and the operation process is complicated.

[0048] During actual operation, the device is connected between the faucet 2 and the water supply port of the washing machine 1. When water is supplied to the washing machine 1, the discharge push rod is driven to push up the one-way valve stem 73 to open the internal channel of the valve housing 71. At the same time, the sealing ring 631 between the liquid outlet joint 72 and the valve housing 71 can be sealed and fitted with the valve housing 71 to prevent detergent from overflowing. The detergent enters the valve housing 71 through the side hole 713 and flows into the inner cavity of the liquid outlet joint 72 through the notch 741 on the liquid outlet push rod 74. Then, the suction pump 9 is started under the control of the controller to pump the extracted detergent into the water outlet pipe 5. When the detergent level in the material barrel 6 drops to the limit position, the liquid level meter collects the signal and transmits it to the controller, and the controller prompts an alarm.

[0049] The operation is convenient and fully automatic. The washing machine 1 will automatically power on and work each time. You only need to place the detergent bucket on the limiter inside the device, and the detergent bucket opening will open automatically. The amount of detergent added can be controlled by controlling the working time of the suction pump 9 by controlling the air. Each time the laundry is washed, the system will automatically and quantitatively dispense the detergent according to the habitual amount of laundry. If the dosage needs to be adjusted, you only need to control the working time of the suction pump 9. When the detergent in the detergent bucket is used up to a low liquid level, the liquid level meter system will automatically alarm and prompt. You only need to take out and replace it with a new bucket. There is no need to manually add detergent to the washing machine 1 every time you wash clothes.

[0050] Furthermore, an ozone generator 10 may be arranged in the device, and the ozone water generated by the ozone generator 10 flows into the washing machine 1 through the suction of the suction pump 9 to sterilize and disinfect the clothes.
