a pressurizer (not shown in the figures) for generating gas, wherein the gas is injected into the storage barrel 202 through the injection port 201, and the washing assistant in the storage barrel 202 is pressed into the water inlet pipe 101.

It should be noted that before the clothes are cleaned, the user can put the washing assistant material in the storage bin 202 through the feeding port 201, and the amount of the washing assistant material in the storage bin 202 can be increased or decreased as needed. A pressurizer can be used to generate a gas, preferably nitrogen, which can be blown into the storage bin 202 from the injection port 201 and force the scrubbing aids in the storage bin 202 into the inlet pipe 101.

After the washing assistant material is added, a user can click a cleaning switch button of the touch panel, and the pressurizer starts to generate gas to press the washing assistant material into the water inlet pipe 101.

As shown in fig. 3, on the basis of the above exemplary embodiment, a feed valve 206 is provided at the connection of the storage tank 202 and the feed pipe 101. Specifically, the user may manually close the feed valve 206 when adding the wash-assist material. In one embodiment, the inlet valve 206 may be connected to a wash switch of the washing machine, the inlet valve 206 being open when the wash switch is open. That is, the inlet valve 206 is closed when the user adds the wash-aid material, and the inlet valve 206 is opened when the user clicks the washing switch of the washing machine, thereby facilitating the entry of the wash-aid material into the inlet pipe 101.

In an embodiment, the inlet valve 206 is connected to a main control board of the washing machine, the main control board is connected to a flow meter, and the main control board is configured to control an opening size of the inlet valve 206 according to a detection result of the flow meter. For example, the main control board may send an electrical signal to the feed valve 206 to control the feed valve 206 to be fully opened when the detection result of the flow meter is greater than the first threshold; when the detection result is smaller than the first threshold and larger than the second threshold, an electric signal is sent to the feed valve 206, and the feed valve 206 is controlled to be opened by half; and when the detection result is smaller than the second threshold value, sending an electric signal to the feed valve 206, and controlling the feed valve 206 to be opened by one third.

That is, the greater the flow rate per unit time, the greater the amount of gas generated by the pressurizer, and thus the more scrubbing agent is injected into the inlet pipe 101 per unit time.

As shown in fig. 2 and 3, the central axis of the injection port 201 is not aligned with the central axis of the discharge port 205. The aperture of the discharge port 205 is smaller than the aperture of the injection port 201. Therefore, even if the feeding valve 206 is not arranged at the discharge port 205, the added washing assistant material cannot directly enter the water inlet pipe 101, the washing assistant material is added to a certain degree, and the washing assistant material is pressed into the water inlet pipe 101 by blowing gas through the pressurizer.

In one embodiment, the main control board in the junction box can control the generation intensity of the ultraviolet lamp tube 102, the amount of silver ions generated by the silver ion generator, the amount of ozone generated by the ozone generator, and the amount of gas generated by the pressure device in the washing assistant material adding device according to the detection result of the flow meter. The larger the flow rate value detected by the flow meter per unit time, the larger the light emission intensity of the ultraviolet lamp 102, the larger the amount of silver ions generated, the larger the amount of ozone generated, and the more gas generated by the pressurizer. Of course, the main control board may be used as only one interface to supply power to each electrical device and perform data transmission between each electrical device. For example, the water inlet apparatus 100 for a washing machine may further include: the main control panel can display the detection result of the flowmeter on the display screen, and a user inputs the control parameters of the ultraviolet lamp tube 102, the silver ion generator, the ozone generator and the pressurizer on the display screen, and the main control panel transmits the control parameters to corresponding devices.
