Abstract
A water-saving system of a domestic water heater comprises the water heater and a water heating tank, the water heating tank is arranged in the water heater, the water heater is connected with a hot water pipe which supplies hot water, the hot water pipe is connected with a tap, water flows out from the tap, a water temperature setting device is arranged on the water heater, and the water temperature can be set manually through the water temperature setting device. The water temperature setting device comprises a third temperature sensor and a central control device, the third temperature sensor is arranged on the hot water outlet of the heater, a two-position three-way valve is connected between the hot water pipe and the tap, a second temperature sensor is connected to the water inlet of the two-position three-way valve, and the two-position three-way valve is provided with one inlet and two outlets. According to the water-saving system of the domestic water heater, the water temperature when the tap is turned on is compared with the preset temperature of the water heater through the two-position three-way valve, the low-temperature water is sent back to the water heater and reheated through the two-position three-way valve if the temperature of the water flowing out from the tap is lower than the preset temperature, the channel between the hot water pipe and the tap is communicated after the temperature of the water flowing out from the tap meets requirements, and hot water is supplied normally.
Description
Technical field
The present invention relates to home-use hot water facility field, especially relate to a kind of pot-type boiler.
Background technology
In present family; People often use water heater; Wash one's hands; Hair washing or bathing; But because water heater still has certain distance apart from the tap of water outlet; Some house design makes water heater far away apart from tens meters of shower heads; Water heater can have been deposited many cold water in the water pipe between tap; Before hot water flows out; These cold water must first be discharged through tap; This has just caused meaningless waste; Because the water heater frequency of utilization is very high; Often waste like this; The waste of saving bit by bit is just larger; The number of users in the whole nation is in necessarily; Waste is just surprising especially; Also virtually improved the water heater use cost; Increase family expense.
Summary of the invention
The object of the present invention is to provide a kind of water-saving system for household water heater, the water resource waste problem that causes because water temperature is lower in the time of can avoiding just having opened hot water.
Technical scheme of the present invention is:
Water-saving system for household water heater; Comprise water heater and the heating water tank that is positioned at water heater; Described water heater is connected with out the hot-water line of hot water; Described hot-water line is connected with the tap of water outlet; Water heater is provided with the water temperature setting device for manual design temperature; The water temperature setting device comprises the three-temperature sensor that is located at the water heater hot-water outlet; Also comprise CCU; Be connected with two position three-way valve between described hot-water line and tap; The water inlet of described two position three-way valve is connected with the second temperature sensor; Described two position three-way valve is provided with an entrance and two outlets; One of them outlet is connected with tap; Another outlet is connected with an end of return pipe; The other end of return pipe is connected with the heating water tank of water heater; Second; Three-temperature sensor and two position three-way valve all with the CCU control connection; Have two working positions during two position three-way valve work; Passage between the passage of conducting hot-water line and tap or conducting hot-water line and return pipe.
The water inlet of described tap is connected with the first temperature sensor, first, second, third temperature sensor and two position three-way valve all with the CCU control connection,
The exit that described two position three-way valve is connected with return pipe is provided with filter.
Be provided with filter between the water inlet of the second temperature sensor and two position three-way valve.
Described two position three-way valve is two-position three way magnetic valve.
The present invention compares by water temperature and water heater preset temperature that two position three-way valve is incited somebody to action when the most initially fetching boiling water tap, if tap place water temperature is low, sending the water of lower temperature back to water heater by two position three-way valve heats again, after tap place water temperature meets the requirements, the conducting hot-water line is to the passage of tap, regular supply hot water.The waste problem that occurs when when the invention solves existing water heater and beginning to open, water temperature is too low, when especially far away apart from tap for water heater, the use problem of pipe inner cold water, be convenient for people to use suitable hot water, do not waste again, all very useful for kitchen, toilet and bathing, satisfy society to the requirement of energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is water-saving system for household water heater, comprises water heater 1 and the heating water tank 2 that is positioned at water heater 1, the hot-water line 3 that the downside of water heater 1 is connected with angle valve and goes out hot water, and the water side of hot-water line 3 is connected with the tap 4 of water outlet.Tap 4 can be the kitichen and toilet tap, the water outlet equipments such as gondola water faucet that use in the time of also can being the shower bathing.
Water heater 1 is provided with the water temperature setting device for manual design temperature, and the water temperature setting device comprises the three-temperature sensor 8 that is located at the water heater hot-water outlet, and water temperature setting device and three-temperature sensor 8 are existing water heater and carry, and belong to prior art.
The present invention also comprises CCU.Be connected with two position three-way valve 5 between hot-water line 3 and tap 4, two position three-way valve 5 is two-position three way magnetic valve.The water inlet of tap 4 is connected with the first temperature sensor 6, the first temperature sensors 6 between tap 4 and two position three-way valve 5.The water inlet of two position three-way valve 5 is connected with the second temperature sensor 7.Two position three-way valve 5 has an entrance P and two outlet A; B; One of them outlet A is connected with tap 4; Another outlet B is connected with an end of return pipe 9; The other end of return pipe 9 is connected with the heating water tank of water heater 2; First; Second; Three-temperature sensor 6; 7; 8 and two position three-way valve 5 all with the CCU control connection; CCU gathers from first; Second; Three-temperature sensor 6; 7; 8 temperature value; Compare; Then transmit control signal to two position three-way valve 5; Make two position three-way valve 5 actions; The passage that conducting is different.But the passage of conducting hot-water line 3 and tap 4, the perhaps passage between conducting hot-water line 3 and return pipe 9.
The exit that two position three-way valve 5 is connected with return pipe 9 is provided with filter 10.Be provided with filter 10 between the water inlet of the second temperature sensor 7 and two position three-way valve 5.It is to stop up two position three-way valve 5 for fear of the incrustation scale that water heater 1 produces that this two place arranges filter, in use for some time, should in time clear up.
Need to prove at last; the water temperature in some seasons is that variation is little; when beginning most to fetch boiling water tap, water flows to the time of tap, the general time when hot water can reach preset temperature; can be by user oneself rule of thumb; the general time of the passage of itself and return pipe 9 of default two position three-way valve 5 conductings on CCU; default Time Delay Opening two position three-way valve 5 leads to the time of the passage of tap 4 simultaneously, within so approximate variation also drops on protection scope of the present invention.
