Hot and cold water control structure for liquid heater

Abstract

The invention discloses a hot and cold water control structure for a liquid heater. The hot and cold water control structure comprises a liquid supply box, a drive pump and a heating tube, wherein the drive pump is installed at the bottom of the liquid supply box; a liquid outlet is formed in the bottom of the liquid supply box, a supply tube convenient for supply of a liquid in the liquid supply box is arranged between the liquid outlet and an inlet of the drive pump, and a liquid pumping tube stretching in the liquid supply box and used for pumping the liquid in the liquid supply box to the top of the liquid supply box is connected to an outlet of the drive pump; an overflow groove convenient for overflow of the liquid pumped by the liquid pumping tube is further arranged at the top of the liquid supply box, and a liquid drainage tube used for guiding the liquid in the overflow groove into the heating tube is connected to the other side of the bottom of the overflow groove; and a hot and cold control device used for controlling whether the heating tube is heated or not and controlling an outlet water temperature of the heating tube by controlling the liquid flow of the liquid flowing out after being heated is connected to the top end of the heating tube, supply for hot and cold liquids through one outlet is realized through the hot and cold control device, and the liquid with a temperature gradually rising to achieve boiling flows out as needed, thus a user is facilitated to select a proper liquid temperature.

Description

【Technical field】 [0001] The invention belongs to the technical field of drinking water appliances, and in particular relates to a cold and hot water control structure of a liquid heater. 【Background technique】 [0002] The rapid development of the household appliance industry has made people have higher and higher requirements for liquid heaters that are frequently used in daily life. Nowadays, there are many types of water boilers on the market, but the general function is single. Some electric heaters are directly placed in water for heating. Its boiling water storage device mainly heats and keeps a certain amount of water in a centralized manner, which causes the disadvantages of water and electricity mixing, repeated boiling, and high energy consumption. In addition, there are also some boiling water devices that can be heated quickly on the market, but the general structural design is unreasonable. It can't make consumers convenient and effective to automatically contr...

[0002] The rapid development of the household appliance industry has made people have higher and higher requirements for liquid heaters that are frequently used in daily life. Nowadays, there are many types of water boilers on the market, but the general function is single. Some electric heaters are directly placed in water for heating. Its boiling water storage device mainly heats and keeps a certain amount of water in a centralized manner, which causes the disadvantages of water and electricity mixing, repeated boiling, and high energy consumption. In addition, there are also some boiling water devices that can be heated quickly on the market, but the general structural design is unreasonable. It can't make consumers convenient and effective to automatically control the water temperature they need to drink, and can't supply cold water. After long-term use, the internal water flow channel is easy to breed bacteria, and it is not easy to clean. It is easy to cause water pollution and affect people's health. It is not suitable for modern people. dietary hygiene needs
