Problems solved by technology

[0004] Most of the solar water heaters are installed on the roof, and a certain length of pipes are needed to connect with the users, and some cold water usually remains in these pipes. It is inconvenient to use hot water directly, and it also causes a lot of waste of water resources
[0005] At present, the method of installing a circulating pump is often used to solve this problem. After the water is used, the remaining water in the pipeline is pumped back to the water tank. However, this method saves water and wastes electric energy. The indoor installed circulating pump is noisy, and the outdoor installation and maintenance Inconvenience, poor equipment reliability
Some people also use a comprehensive utilization system that adds a complex circuit control and sensor output, so the design cost is relatively high

Embodiment Construction

[0033] Such as Figure 1-2 As shown, a water-saving temperature control device for a water heater includes a downpipe 5 , a first water tank 1 , a power supply 12 , a main switch 11 , a rheostat 10 , and a valve 13 . The power supply 12 is a low voltage direct current power supply 12 . A plurality of water pipe branches are sequentially branched out along the water discharge direction of the sewer pipe 5, which are successively the first water outlet pipe 16 leading the water in the first water tank 1 into the sewer pipe 5, the drain pipe 14 for the entire device to discharge water, Water is introduced into the first water inlet pipe 15 of the first water tank 1 . The water inlet of the downpipe 5 is connected with a solar water heater 17 . Wherein the first water outlet pipe 16 injects the cold water in the first water tank 1 into the hot water in the downwater pipe 5 .

[0034] The downpipe 5 above the first outlet pipe 16 is provided with a thermistor 6 for detecting the...

Abstract

The invention discloses a water-saving temperature control device for a water heater. The device comprises a downcomer and a first water tank, wherein a plurality of water pipe branches are successively divided outside along the water down direction of the downcomer to lead water in the first water tank to a first water outlet pipe in the downcomer, a drain pipe for draining water of the whole device and a first water inlet pipe for introducing water into the first water tank successively. A thermistor for detecting the water temperature at the position is arranged on the downcomer above the first water outlet pipe, a normally closed temperature switch for inducing the water temperature in the position is arranged on the downcomer between the first water outlet pipe and the drain pipe; a first normally closed electromagnetic valve is arranged on the first water outlet pipe, a normally open electromagnetic valve is arranged on the drain pipe, and a second normally closed electromagneticvalve is arranged on the first water inlet pipe. The water-saving temperature control device disclosed by the invention has the advantages that by additionally arranged the first water tank, the water temperature of water discharged from the drain pipe is a preset water temperature by detecting the whole circuit, so that the energy source is saved greatly, and the water using comfort level is also guaranteed.

Description

technical field [0001] The invention relates to the water-saving field of water heaters, in particular to a water-saving temperature control device for water heaters. Background technique [0002] With the development of urbanization in our country, people's demand for water resources is increasing day by day. However, fresh water resources are not inexhaustible. Therefore, the awareness of saving water resources should also be strengthened day by day. In recent years, solar water heaters have occupied a large share in the domestic water heater market. According to the structure, solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters. At present, vacuum tube solar water heaters are the main ones. Vacuum tube household solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into heat mainly depends on vacuum heat collecting tubes. Get the ...
