Water drinking machine capable of providing boiled water

Abstract

There is a boiling-water drinking trough, which contains power circuit 1, operating circuit 2, monolithic circuit 3, water-yielding circuit 4, alarm circuit 6, indicating circuit 7 and warming and protection circuit8, and these circuit all link with the corresponding interfaces of monolithic circuit 3 separately. Its characteristic is that it also contains auxiliary heating controlling circuit 5 and connecting line from point A to interface 13 of monolithic circuit 3.The triode Q2 base electrode of auxiliary heating controlling circuit 5 connect with interface 25 of monolithic circuit 3 through electric resistance R13, and the Q2 electron collector connects with relay J2. Diode D5 stridently joined with both sides of relay J2 to reheat and boil water. This drinking trough solves the problem of supplying warm water only, and it fulfils the need of drinking, dunking tea and punching food.

Description

technical field [0001] The invention relates to the improvement of a water dispenser, in particular to provide a boiling water dispenser. technical background [0002] Water dispensers have been widely used in families and public places, providing great convenience for people to drink water. There are two kinds of temperature control and protection circuits for water dispensers sold on the market. One is to use two metal sheet temperature controllers, one for heating and the other for protection. K in the circuit diagram of the present invention 9 、K 10 That's it. Two thermostats, K 9 The transition temperature is 85°C±5°C, K 10 The temperature of the jump is 95 ° C ± 5 ° C, the temperature of drinking water is around 90 ° C, not reaching the boiling point; the other is K 9 It adopts electronic temperature sensor and is controlled by single-chip microcomputer circuit, which can carry out temperature setting and temperature display, but it is also subject to K 10 The tri...

There are two kinds of temperature control and protection circuits for water dispensers sold on the market. One is to use two metal sheet temperature controllers, one for heating and the other for protection. K in the circuit diagram of the present invention 9 、K 10 That's it. Two thermostats, K 9 The transition temperature is 85°C±5°C, K 10 The temperature of the jump is 95 ° C ± 5 ° C, the temperature of drinking water is around 90 ° C, not reaching the boiling point; the other is K 9 It adopts electronic temperature sensor and is controlled by single-chip microcomputer circuit, which can carry out temperature setting and temperature display, but it is also subject to K 10 The trip temperature is limited to 95°C due to K 10 The error range is within ±5°C, if the K 10 If the jump temperature is set a little higher, it will cause the heating to keep heating without disconnection, and the protection function will be lost.

The defects of the existing technology are obvious, especially the Chinese and Asians have a long history of tea culture, and it is a pity that there is no boiling water to make tea. It is a pity that the tea with water at about 90°C cannot activate the proper taste of the tea, and the taste cannot be brewed. In addition, food that needs to be prepared with boiling water cannot be processed, such as lotus root powder, sesame paste, etc., which is very inconvenient for patients, the elderly, and children who need to prepare food
