Automatic water-taking refrigerator and its water valve control method

Abstract

The invention discloses an automatic water taking refrigerator. The refrigerator comprises a door body, a distributor which is arranged on the door body and provided with a water outlet, a water valvefor controlling the water outlet to be opened or closed, and a sensing device arranged on the distributor and used for sensing a water taking container; the distributor comprises a supporting surfacewhich is arranged towards the water outlet and used for supporting the water taking container; the sensing device comprises a first pair of sensors and a second pair of sensors, the first pair of sensors comprise a first transmitting end and a first receiving end, and the second pair of sensors comprise a second transmitting end and a second receiving end; the water outlet is provided with a center line, connecting lines among the shadow of the first transmitting end, the shadow of the first receiving end and the shadow of the center line which are projected on the supporting surface form a triangle, and the shadow of the second transmitting end, the shadow of the second receiving end and the shadow of the center line which are projected on the supporting surface are located on the same straight line. According to the automatic water taking refrigerator, the position of the water taking container can be determined more accurately, and the automatic water taking refrigerator is safer and more reliable to use.

Description

technical field [0001] 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 [0002] 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. [0003] Chinese invention patent CN200810147161.8 discloses a refrigerator with automatic water ...

AI Technical Summary

Problems solved by technology

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. Valve signal, can't get water at all

Therefore, in this reference document, the position sensing of the water intake container is not accurate, and the water intake container is not under the water outlet, and the water valve is opened, which is unsafe to use.

Moreover, even if the water intake container with a smaller diameter is located at the water intake position, the water valve is closed, and the water intake cannot be taken at all.

In summary, this refrigerator is unreliable and unsafe to use
