Description

heating device for drinking water

technical field

The utility model relates to a water heating device, in particular to a drinking water heating device.

Background technique

Drinking water heating equipment is an indispensable equipment in people's daily life. It is easy to realize if only the water is heated intermittently in batches to make warm water, hot water or boiled water for people to drink directly. Only the container is equipped with a heating device, and the water in the container can be taken on demand after being heated within a certain period of time . However, if it is a direct current drinking water machine with an uncertain use time, the heating equipment becomes very complicated and requires high technical requirements. The water in the measuring container is boiled and stored. When the real-time temperature is lower than the preset temperature, the heater is automatically driven to heat the water. Since the water is continuously heated, cooled, and heated, the water may constitute the so-called "thousand boiling water". As we all know, "Thousand boiling water" is the stagnant water referred to in traditional Chinese medicine. It is not suitable for long-term drinking. According to modern scientific interpretation, it means that after countless times of boiling water, the heavy metal substances in the water will be concentrated, and the deuterium content in the water will also decrease due to the evaporation of light water. Concentration increases, so long-term drinking will damage human health; second, that is, instant heating, cold water flows through the equipment to achieve heating, this equipment certainly solves the technical problem of "thousand boiling water", but it has derived another The technical problem is that the energy consumption required to heat a certain flow of water to the set temperature is certain. For example, the energy required to heat the water with a flow rate of 3L/min to 95 degrees immediately is about equal to the thermal power installed capacity of 6kw. , That is, the installed machine needs a heating power element of 6kw. In this way, another difficult problem has come again. Such a large installed power is unbearable for the sockets and circuit lines configured in homes and offices.

In view of the above description, there is a need in the existing market for an instant heating technology and machine that has low installed power and cannot be made into "thousand boiling water" to meet people's daily needs for direct drinking hot water.
