Embodiment 1

[0045] Such as image 3 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.

[0046] When the user uses the washing machine, the washing machine automatically detects the presence or absence of detergent during the start-up process. When the detergent is out of the controllable range, it uses sound and light to remind the user to add detergent in time. When the user does not replenish When the detergent ...

Embodiment 2

[0052] Such as Figure 4 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 the passages 15a, 15b are respectively provided with electromagnetic valves 15c, 15d at the connection ports of 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 . Wherein, the passage 15a communicates with the detergent container 2 containing detergent, and the passage 15b communicates with the de...

Abstract

The invention discloses a device and method for detecting a detergent existence state in a washing machine. The device is characterized in that two electric-conducting metal probes are arranged a detergent container capable of being automatically placed with detergent and are connected with a controller, and the detergent existence state of the detergent container can be judged by detecting electric conductivity between the two electric-conducting metal probes inside the detergent container. The detergent existence state is detected in each starting process of the washing machine, when the detergent exists beyond a controllable range, a user is prompted in an acoustooptic manner to supplement the detergent in time, and when the user does not supplement the detergent, the washing machine stops work so as to avoid waste; detection can also be carried out after clothes are washed, and the prompt is performed in the acoustooptic manner as well when no detergent is detected. The device and the method disclosed by the invention have the advantages of low cost and high accuracy and are insusceptible to outside interferences.

Description

technical field [0001] The invention relates to a washing machine, in particular to a washing machine capable of automatically adding detergent, in particular to a device and a detection method capable of detecting whether there is detergent in the washing machine. Background technique [0002] Along with the continuous improvement of degree of automation, the washing machine with automatic washing detergent function also appears on the market successively on the full-automatic washing machine, and there is the trend of continuous continuous development, in the washing machine with liquid detergent storage and automatic feeding function, due to Detergent is preset in the detergent storage container, so when the detergent is about to run out or is exhausted, it is necessary to remind the user of the remaining detergent when the washing machine starts to work, reminding the user to add detergent before washing, to avoid Because the clothes are still washed without knowing that...
