Water dispenser heating device

Abstract

The invention relates to a heating device, and discloses a heating device of a water dispenser. The heating device comprises a thermal container cavity (1) which is internally provided with a heating pipe (11) and a steam-water separation tank (3) which is located above the thermal container cavity (1) and communicated with the thermal container cavity (1) through a hot water pipe (2); a support (31) is fixed in the steam-water separation tank (3) and internally provided with a micro switch (32) which is electrically connected with the heating pipe (11), an air inlet (310) corresponding to a pipe opening of the hot water pipe (2) is formed in the bottom of the support (31), a bimetallic strip (33) is arranged on the portion, above the air inlet (310), inside the support (31), and a lever (34) capable of pressing the bimetallic strip (33) is hinged to the support (31). The heating device of the water dispenser has the advantages that use is convenient, the heating speed is high, hot water output can be quantified, output hot water temperature is stable, repeated heating does not occur, the water quality is safe, and the problem of failing in water output due to limescale cannot occur in hard water heating.

Description

technical field [0001] The invention relates to a heating device, in particular to a heating device for a water dispenser. Background technique [0002] With the improvement of people's living standards, water dispensers have become an essential product for ordinary families. One of the more popular water dispensers in the market is a heating system without a heat tank, which is made of quartz tube electric heating tubes (or stainless steel tube electric heating tubes). , thermostat, balance water tank and raw water tank, etc. The balance water tank is to provide a constant water level for the heating body. The water level will affect the temperature of the water outlet and the speed of the hot water outlet. The balance water tank is generally fixed. Due to the change of the ambient temperature (winter and summer) Very large: In winter, the water outlet temperature is low and the water output is small, and in summer, the warm water temperature is high, and there is a large ...

AI Technical Summary

Problems solved by technology

When the temperature is lower than a certain temperature, the water dispenser will automatically heat again, so that the water in the hot tank will be heated repeatedly (so-called "thousand boiling water"), which not only wastes electric energy, but also makes the heating tube continue to heat, shortening its service life. , and the water heated repeatedly will cause the nitrite in the water to increase and the dissolved oxygen in the water to decrease. Such water is no longer conducive to health.

But if you don't turn on the water dispenser, you have to wait for a long time to heat the water when you need water, which is very inconvenient to use

[0004] At the same time, the hot water of the water dispenser is driven by water gravity (water level difference), so the original water tank, hot water tank and water outlet must have a certain height difference (that is, water level difference) during product design, and the greater the height difference, the greater the water outlet speed. fast, resulting in high design height and large size of such products
