The liquid inlet of the water collecting device is connected with the water inlet pipeline 5 of the washing machine through the connecting pipe 6, and the liquid outlet is connected with the liquid inlet end of the spray pipe 7; when a user manually puts in the laundry treatment agent, the dispenser box is firstly pulled out from the water collecting device from the outside of the drum washing machine, the laundry treatment agent is put into the accommodating chamber of the dispenser box, and then the dispenser box is pushed into the water collecting device. In the washing water inlet process, domestic water enters a liquid inlet of the water collecting device through a faucet and a connecting pipe 6, water flows in the liquid inlet of the water collecting device, a clothes treating agent in a containing cavity of the distributor box enters the water collecting device along with water flows, the clothes treating agent is fully mixed with water in the water collecting device, finally enters a spray pipe 7 path through a liquid outlet of the water collecting device, and the clothes treating agent enters an inner barrel along with water flows in the spray pipe 7 path through a window screen 3 of the drum washing machine.
The drum washing machine of the embodiment further comprises a water inlet valve 8 for controlling the on-off of the spray pipe 7, wherein the water inlet valve 8 is arranged on the connecting pipe 6, and particularly, the water inlet valve 8 is arranged at the joint of the connecting pipe 6 and the water inlet pipe 5, and the water inlet valve 8 is an electromagnetic valve.
The connection mode between the pipelines and the control valve, and between the pipelines and the faucet is that the pipelines are connected through connectors, wherein the connectors are plug connectors or screw connectors or other connector modes capable of connecting the two pipelines.
As shown in fig. 5, the present embodiment further proposes a control method of the drum washing machine, where the control method includes: the washing machine controls whether the washing machine performs washing water inlet/rinsing water inlet by controlling the on-off of the spray pipe 7. When the liquid inlet end of the spray pipe 7 is connected with the liquid outlet of the distributor box assembly 4, the control method comprises the following steps:
In the washing/rinsing water inlet process, the water inlet valve 8 is controlled to be opened, water flows from the water inlet pipeline 5 of the washing machine, flows through the connecting pipe 6 and the distributor box assembly 4, finally flows into the washing machine through the spray pipe 7, and when the preset water inflow is reached, the water inlet valve 8 is controlled to be closed.
Also included in the washing and/or rinsing process is the spraying of the window screen 3 and/or window mat, the control method comprising: during the washing and/or rinsing process, when the washing machine is operated for a first preset time, the water inlet valve 8 is controlled to be opened, and after a second preset time is reached, the water inlet valve 8 is controlled to be closed. Furthermore, the water inlet valve 8 can adjust the water inlet flow according to the running program of the washing machine, and the water inlet valve 8 is controlled to be opened at different water inlet flow in the water inlet process of different running programs of the washing machine. Specifically, during the water intake process of the washing/rinsing process, the water inlet valve 8 is controlled to be opened at a first water intake flow rate, and during the water intake process of the window screen 3 and/or the window pad cleaning, the water inlet valve 8 is controlled to be opened at a second water intake flow rate, wherein the first water intake flow rate is greater than the second water intake flow rate. Since the washing water inlet and the rinsing water inlet need to be opened with a larger water inlet flow rate to rapidly complete the water inlet process, and the cleaning of the window screen 3 and/or the window pad needs only a smaller water flow rate, the water inlet valve 8 is controlled to be opened with a larger water reducing flow rate in the washing water inlet and the rinsing water inlet process, and the window screen 3 and/or the window pad is controlled to be opened with a smaller water inlet flow rate in the cleaning process.
The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
