Problems solved by technology

[0002] Adding detergent, softener, bleach, softener and other additives to the current washing machine needs to be done manually, and the dosage must be controlled by the user. Improper dosage will cause poor washing effect
For example, when washing lightly soiled clothes, adding too much detergent will cause severe foaming and poor rinsing; when washing clothes that are easily decolorized, excessive use of bleach will cause the clothes to decolorize

Embodiment 1

[0056] A control method that takes the volume of the buffer zone of the metering valve as the unit of measurement

[0057] When the volume of the buffer zone 5 is 1ml, the accuracy of the liquid delivery volume controlled by the washing machine can be achieved, and the required additive is 3ml, and then the control process of a liquid delivery is firstly completed.

[0058] First, control the emptying valve 4 and the water outlet valve 2 to act simultaneously, the action time T1 is 6 seconds, fully empty the liquid in the buffer zone 5 and the buffer zone 5 in the same direction as the washing bucket, and close the emptying valve 4 and Water outlet valve 2, while shutting off the emptying valve 4 and water outlet valve 2, the air valve 6 installed on the additive storage box 7 is opened to ensure that the pressure of the additive storage box 7 is balanced with the external air pressure, so that the liquid in the box can flow smoothly After T2 time is 2 seconds to control the a...

Embodiment 2

[0062] Control method with flow rate of additive supply valve 3 as measurement unit

[0063] The volume of the buffer zone 5 does not need to be set, but it is larger than the additive capacity that needs to be added. The amount of additive that needs to be added is related to the T3 time that controls the action of the additive supply valve 3. Here, T3 is determined by the amount of additive that needs to be added and the additive supply. The ratio of the flow rate of valve 3 is calculated, and the flow rate of the additive supply valve 3 is inherent. You only need to input the amount of additive to be added into the computer board to obtain the time of T3, and the time of T3 can also be calculated artificially. .

[0064] Firstly, control the emptying valve 4 and the water outlet valve 2 to act simultaneously, and the action time T1 is 7 seconds to fully empty the liquid in the buffer zone 5 and the circuit of the washing bucket in the same direction as the buffer zone 5, an...

Abstract

The control process of supplying washing additive includes the following steps: for the computer in the washing machine to send command, for the output driver circuit to send the command to the additive metering unit, for the valves receiving the command to meter and throw the additive in the required amount. The present invention is especially suitable for washing machine with independent additive device to add liquid detergent, softening agent, bleaching agent, softener or other additive in the precision within 1 g and proper time.

Description

technical field [0001] The present invention relates to a control method, in particular to a control method for supplying detergent additives. Background technique [0002] Adding additives such as detergent, softener, bleach, and softener to the current washing machine needs to be done manually, and the dosage must be controlled by the user. Improper dosage will cause bad washing effect. For example, when washing lightly soiled clothes, adding too much detergent will cause severe foam and not rinse well; when washing clothes that are easy to decolorize, excessive use of bleach will cause the clothes to decolorize. [0003] In view of the above-mentioned defects of the existing washing machine in dispensing detergent, how to design a washing machine with the function of automatically and quantitatively dispensing detergent has become the research and development goal of those skilled in the art. Contents of the invention [0004] The object of the present invention is to ...
