Description

A water dispenser that prevents repeated heating

technical field

The utility model relates to a water dispenser, in particular to a water dispenser that prevents repeated heating.

Background technique

 A water dispenser is a device that heats up bottled water (usually pure water or mineral water) and makes it convenient for people to drink.

The water dispenser of traditional structure is that heating tank is built in fuselage interior. In order to avoid the problem of water pipe bursting caused by overheating of the water temperature in the built-in heating tank, the heating control circuit does not limit the temperature of the heating water in the heating tank to the boiling point (usually about 90°C). Thereby, the water dispenser of traditional structure has the problem of thousands of boiling water and yin and yang water, and long-term drinking is unfavorable for human health.

In recent years, with the improvement of people's health awareness, water dispenser merchants have also introduced various water dispensers that prevent repeated heating. Although these anti-reheating water dispensers have different shapes, their main structures are basically the same, that is, an open water cup holder is set on the outer wall of the fuselage. The water cup holder is actually an electric heater, which is matched with a matching heating kettle Realize the heating action outside the fuselage. However, this heating method not only leads to high manufacturing cost of the water dispenser due to factors such as heater selection and embedded design; moreover, this heating method makes the heating kettle placed in an open environment outside the fuselage, and there is a large noise during the heating process. problem; in addition, the existing anti-repeated heating water dispensers do not have the alarm prompt function, and the water dispensers lacking this function have the problem of reheating water that is not conducive to health. This is because: according to people's living and working habits, when heating After injecting water into the kettle and triggering the heating element, it will not stay in place and wait for a few minutes, but go to work on other tasks at hand. When the task at hand is finished and you want to drink water, the heated water is usually in a lukewarm state and cannot be used for The brewing of beverages such as coffee and tea needs to be reheated.
