Backflow preheating water supply system

Abstract

The invention provides a backflow preheating water supply system, which is characterized in that a water tank of the water supply system supplies water to a balanced reservoir through a water pump and supplies water to a water outlet switch and a heater from the balanced reservoir through the water pump, the water pump is directly communicated with the bottom of the balanced reservoir through a water feeding pipe, and the balanced reservoir is communicated with the bottom of the heater; the balanced reservoir comprises a backflow cavity and a water level balance cavity; the backflow cavity is arranged on an overflow port at the top of the heater and is communicated with the overflow port; wherein the horizontal height of the water level balance cavity is equal to that of the heater, a first water level baffle is arranged in the water level balance cavity, and the first water level baffle is divided into a first area and a second area; and the height of the first water level baffle is lower than that of the overflow port in the horizontal direction. According to the backflow preheating water supply system provided by the invention, multiple preheating backflow can be completed, heated water flows back to the reservoir, meanwhile, the initial temperature of the reservoir is increased in a repeated backflow mode, boiling and expanding water in the heater can only enter the backflow cavity through the overflow port of the heater, it is guaranteed that outlet water is really boiling water, and the temperature is higher.

Description

【Technical field】 [0001] The invention relates to the technical field of water purifiers and water purifying equipment, in particular to a water purifying water supply system that uses a backflow water source to preheat a water tank. 【Background technique】 [0002] With the continuous improvement of the public's living standards and quality of life, the pursuit of high-quality life is also gradually increasing, and the quality requirements for daily necessities are also increasing. For example, the problem with the traditional instant hot water dispensers on the market today is that the flow rate is relatively small in order to ensure the heating effect. Therefore, increasing the hot water flow rate has become the focus of manufacturers and research and development. However, based on the law of energy conservation, it is necessary to increase the hot water flow rate, which requires increasing the heating power. Based on the safety considerations of household appliances, blin...

Problems solved by technology

Therefore, improving the hot water flow rate has become a key focus of manufacturers and R&D. However, based on the law of energy conservation, it is necessary to increase the hot water flow rate, which requires increasing the heating power. Based on the safety considerations of household appliances, blindly increasing the power has potential safety hazards.
