Description
Technical Field
The invention relates to the field of household appliances, in particular to an automatic water taking refrigerator.
Background
At present, high-grade refrigerator products have widely used the door body to get water and get the ice function. The traditional refrigerator ice water distributor generally adopts a water taking push mechanical switch or set water injection or ultrasonic detection water injection; however, the above methods have disadvantages in that the mechanical switch type is poor in sealing property, easy to ignite, easy to rust, etc., and thus, the mechanical switch type becomes ineffective. Setting the water injection is mainly dependent on water pressure balancing or metering devices and is also very unreliable. Ultrasonic detection has the disadvantages of high precision and high price.
Chinese patent CN200810147161.8 discloses an automatic water intake refrigerator, which is provided with a water outlet for controlling a water valve and an induction device for inducing a water intake container, wherein the induction device at least comprises a first pair of infrared sensors arranged close to the water outlet and a second pair of infrared sensors arranged at intervals with the water outlet and positioned at the inner side of the water outlet, each pair of infrared sensors comprises an emitting end for emitting infrared rays and a receiving end for receiving infrared rays, when water is taken, the water intake container is simultaneously inserted between the emitting end and the receiving end of the two pairs of infrared sensors to cut off infrared signals, at the moment, a signal for opening the water valve is triggered, namely, the infrared signals of the two pairs of sensors are cut off, and then the signal for opening the water valve. When water intake is finished, when the water intake container is moved to a position, the infrared signal of the infrared sensor 40 is firstly switched on, and at the moment, a signal for closing the water valve is triggered, so that water intake is finished. In this patent, if the water intaking container moves to the direction that is close to the water intaking chamber back wall, moves to the position that can cut off two infrared sensor's infrared signal, and no longer is located the below of delivery port, and the water valve still is triggered to open this moment. Or the diameter of the water taking container is smaller, when the water taking container is placed at a water taking position, the infrared signal of the infrared sensor 30 can be only cut off, but the infrared signal of the infrared sensor 40 is not cut off, namely, the infrared sensor is connected, at the moment, the signal for closing the water valve is triggered, and water cannot be taken at all. Therefore, the comparison file is inaccurate in position induction of the water taking container, the water taking container is not positioned below the water outlet, and the water valve is opened, so that the comparison file is unsafe to use. And the situation that water cannot be taken at all occurs when the water valve is closed even if the water taking container with the smaller diameter is positioned at the water taking position. In conclusion, the refrigerator is unreliable and unsafe to use.
