Embodiment Construction

[0053] Such as image 3 As shown, the washing machine according to the present invention includes a water inlet 1, a detergent container 2 and a water tank 3, and two water inlet passages are arranged between the water inlet 1 and the water tank 3, which are respectively the main water inlet 4 and the cleaning water way 5. There is a main water inlet valve 6 between the main water inlet 4 and the water inlet 1, a cleaning water valve 7 between the cleaning waterway 5 and the water inlet 1, and a constant volume container between the cleaning waterway 5 and the water tank 3 8. The constant volume container 8 communicates with the detergent container 2. The main water inlet 4 is provided with a Venturi tube 9 capable of generating negative pressure through the flow of water. The rear side of the outlet of the Venturi tube 9 is provided with a side branch pipe 10 and constant volume The container 8 is connected, and the water flow of the main water inlet 4 passes through the Vent...

Abstract

The invention discloses a method for judging the time of detergent automatic dispensing system and a washing machine. The automatic dispensing system utilizes the Venturi effect formed in the Venturi tube by the water entering the main water inlet, so that the constant volume container generates a relatively low pressure area, which is consistent with the The detergent in the detergent container connected to the constant volume container enters into the constant volume container under the action of atmospheric pressure. In the water bucket, during the water intake process of the main water channel before starting to inject detergent, by detecting the water intake flow rate, comparing it with the relationship between the water intake flow rate stored in the washing machine and the time used for a single suction of detergent, determine the time for each pumping. The time it takes to fill the constant volume container with detergent. The judging method of the invention has the characteristics of accurate judging, avoids excessive injection of detergent, realizes full automation of the laundry process, and improves laundry efficiency.

Description

technical field [0001] The invention relates to a washing machine and a detergent feeding method, in particular to a judging method for accurately controlling detergent feeding time and a washing machine with the judging method. Background technique [0002] Existing a large amount of patent application of relevant detergent automatic dispensing device at present, the Chinese patent that application number is 97208723.0 discloses a kind of washing machine detergent adding device, and it is to be provided with the cavity that cooperates with bottle on the washing machine cabinet, the cavity of cavity The bottom is a conical through hole, and a vertical fixing piece is fixed on the through hole, and the vertical fixing piece fixes the washing liquid conduit. The bottle body matches the cavity, and a conical inlet tube is arranged on the bottle mouth, and there is a ventilation port at the bottom of the bottle body . This structure cannot control the amount of detergent added,...
