Embodiment 1

[0035] Such as figure 1 As shown, the control valve 11 provided at the connection between the constant volume container 8 and the side branch pipe 10 is a buoyancy ball valve, the control valve 16 provided between the constant volume container 8 and the washing bucket 3 is a one-way control valve, and the cleaning water valve 7 Corresponding two detergent containers are provided with passage 12a and passage 12b between constant volume container 8, are respectively provided with electromagnet 13a, 13b and magnet ball valve 14a, 14b on passage 12a and passage 12b, constant volume container 8 and detergent container 2 are passages 15a, 15b respectively.

[0036] Before the main water inlet 4 starts to enter water, the constant volume container 8 is closed with the cleaning waterway 5 and the washing bucket 3, and the constant volume container 8 is connected with the main water inlet 4 and connected with the detergent container 2 , that is, the electromagnets 13a, 13b attract and...

Embodiment 2

[0040] Such as figure 2 As shown, the control valve 11 provided at the connection between the constant volume container 8 and the side branch pipe 10 is an electromagnetic valve, and the control valve 16 provided between the constant volume container 8 and the washing bucket 3 is a buoyancy ball valve or an electromagnetic valve. The container 8 communicates with the detergent container 2 containing the washing liquid and the softener respectively, and electromagnetic valves 15c and 15d are respectively provided at the connection ports of the passages 15a, 15b and the constant volume container 8, and the connection between the cleaning water valve 7 and the constant volume container 8 There is only one passage 12 between them, and a solenoid valve 13 is also provided at the connection between the passage 12 and the constant volume container 8 .

[0041] When the main water inlet 4 enters water, open the control valve 11, solenoid valves 15c, 15d, and close the solenoid valve ...

Abstract

The invention discloses a washing method and a washing machine for adding detergents automatically under negative pressure. The washing machine comprises a water inlet, a detergent container and a washing barrel, wherein two water inlet channels are formed between the water inlet and the washing barrel, namely a main water inlet channel and a water cleaning channel; a constant volume container is arranged between the water cleaning channel and the washing barrel, and is communicated with the detergent container; a Venturi tube is arranged in the main water inlet channel; thick main water inlet flow is changed to thin main water inlet flow by utilizing the principle of a Venturi effect, and the water inlet flow speed is accelerated, so that a relative vacuum area is formed on the rear side of an outlet of the Venturi tube; and the relative vacuum area is communicated with the constant volume container, so that the constant volume container pumps the detergents in the detergent container communicated with the constant volume container to constant volume container under the negative pressure. By the washing method, the proper amount of detergents are added automatically under the negative pressure generated by the water flow on the premise that the washing effect is not influenced, the structure is simple, and the washing efficiency is improved.

Description

technical field [0001] The invention relates to a washing machine and a washing method, in particular to a washing method and a washing machine which automatically add detergent by using the negative pressure generated by water inflow. Background technique [0002] The detergent used in the washing process of the 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. This structure cannot realize the automatic washing control process of the washing machine. With the improvement of washing machine automation, most washing machines are set to connect the detergent box for placing detergent or / and softener with the water inlet pipeline, and flush the detergent or / and softener in the detergent box into the washing tub through the water inlet However, this structure must first put detergent or / and softener into the detergent box every time the laundry i...
