Description

Automatic water-taking refrigerator and its water valve control method

technical field

The invention relates to the field of household appliances, in particular to an automatic water-taking refrigerator and a control method for a water valve thereof.

Background technique

At present, high-end refrigerator products have widely used the functions of water and ice from the door body. The traditional refrigerator ice water dispenser usually uses water intake to push the mechanical switch or set water injection or ultrasonic detection water injection; but the above methods have disadvantages, among which the mechanical switch type has poor sealing performance, easy to catch fire, easy to rust, etc., resulting in invalidated. Setting water injection mainly relies on water pressure balance or metering devices, which are also very unreliable. Ultrasonic detection not only has the disadvantages of detection accuracy, but also is expensive.

Chinese invention patent CN200810147161.8 discloses a refrigerator with automatic water intake, which is provided with a water outlet for controlling the water valve and an induction device for sensing the water intake container. The second pair of infrared sensors is set at intervals from the water outlet, and each pair of infrared sensors includes a transmitting end for emitting infrared rays and a receiving end for receiving infrared rays. Block the infrared signal. At this time, the signal to open the water valve is triggered, and the water intake starts. That is, the infrared signals of both pairs of sensors must be blocked to trigger the signal to open the water valve. When the water intake ended, when the water intake container was moved, the infrared signal of the infrared sensor 40 was connected at first, which triggered the signal to close the water valve, and the water intake ended. In this patent, if the water intake container moves towards the rear wall of the water intake chamber to a position where the infrared signals of the two infrared sensors can be cut off, and is no longer located below the water outlet, the water valve is still triggered to open. Or the diameter of the water intake container is relatively small. When it is placed in the water intake position, the infrared signal of the infrared sensor 30 can only be cut off, but the infrared signal of the infrared sensor 40 is not cut off, that is, it is connected, but this time it is triggered to turn off the water. The signal of the valve, can't get water at all. Therefore, in this reference document, the position sensing of the water intake container is inaccurate, and the water intake container is not below the water outlet, and the water valve is opened, which is unsafe to use. And there is a water intake container with a smaller diameter even if it is positioned at the water intake position, but the water valve is closed, and the situation that water intake cannot be taken takes place at all. In summary, this refrigerator is unreliable and unsafe to use.
