Description

A special smart socket for water dispenser

technical field

The utility model relates to the technical field of smart sockets, in particular to a special smart socket for water dispensers.

Background technique

Water dispenser is an indispensable electrical appliance in daily production. In order to meet people's daily drinking water needs, water dispensers are found in all corners of social life, such as families, factories, schools and so on. However, due to various reasons, people often forget to turn off the water dispenser or cannot turn off the water dispenser in time as needed, resulting in the water dispenser repeatedly boiling water all night, which not only consumes a lot of electricity, but also drinking this repeatedly burned water is also harmful to health. At the same time, it also greatly reduces the service life of the water dispenser. Through the analysis of the power supply principle of the water tank in the water dispenser, it is found that after the water in the water tank is boiled, the power is cut off and the heating is stopped. It will slowly dissipate heat and cool down. When the temperature drops to the pre-set heating lower limit, the water dispenser will control the heating again. Because the heating case is wrapped with materials with good thermal insulation performance, the heat dissipation rate is relatively slow, so that the time interval between the two heating of the water tank of the water dispenser is long, generally more than ten minutes. If the user uses up all or part of the hot water after the water is boiled, the temperature of the water in the water tank will quickly drop to the lower heating limit. In this way, the heating time for two drinking water heating times will be greatly shortened. There is no interval between measuring the two heating times, so as to determine whether the user has poured water. If there is no user pouring water after heating for two consecutive times (which can be set to different values according to actual needs), the water dispenser will be directly turned off and the current It can be done in the water dispenser, but there are a large number of water dispensers in all corners of the society, and the current water dispenser production line is basically formed and tends to be stable, this design will seriously increase the water dispenser. The design time cost and economic cost are not conducive to the promotion of the existing water dispenser market. The judgment of whether the current is available can also be completed on the transmission line. Due to the single function of the traditional power socket, unless the user actively cuts off the power supply, it cannot be realized. The function of cutting off the power supply according to actual needs.

To sum up, the present invention proposes a special intelligent socket for a water dispenser to solve the existing problems.
