Control device for water dispenser and water dispenser

Abstract

The invention relates to the field of household appliances, and discloses a control device for drinking water and a water dispenser, the device comprises an ultrasonic detection device configured to detect that an object enters a water outlet area of the water dispenser and receive a detection signal in response to the object entering the water outlet area; a weight detection device configured to detect a weight of the object; and a processor configured to acquire a detection signal, determine that the object is a water receiving container according to the detection signal; determine that the object is a water receiving container according to the weight; and control the water dispenser to discharge water. The water leakage accidents or personal potential safety hazards caused by mistaken water discharge of the water dispenser are prevented, and the recognition accuracy and the use experience of the water dispenser for the water container are improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a control device for drinking water and a water dispenser. Background technique [0002] Most of the existing water dispensers use ultrasonic detection equipment to help control automatic water discharge. Specifically, the processor controls the water discharge and water stop actions of the water dispenser according to the detection results of the ultrasonic detection equipment on whether there is a water cup in the water receiving area. When the user places the quilt When arriving at the water receiving area of ​​the water dispenser, the ultrasonic testing equipment detects that an object of a certain height enters the water receiving area, and the water dispenser starts to discharge water. However, the ultrasonic testing equipment can only detect the height information of the measured object, and cannot distinguish whether the object entering the water receiving area is a wa...

AI Technical Summary

Problems solved by technology

However, the ultrasonic testing equipment can only detect the height information of the measured object, and cannot distinguish whether the object entering the water receiving area is a water cup or other objects (such as sticks, spoons or users' hands), that is, the radiation emitted by any object entering the ultrasonic testing equipment The area will reflect the echo wave, forming a peak signal as complete as the water cup. It is difficult to ensure 100% accuracy of the water cup recognition, so that the processor program mistakenly believes that the object entering the water receiving area is a water cup and controls the water dispenser to automatically discharge water. If the situation is light, it will cause a water leakage accident, and if it is serious, it will lead to personal safety hazards.
