The utility model discloses can guarantee to open the power just can flow out hot water, can solve traditional water heater and open and have a very long section cold water exhaust problem, and under the great environment of the difference in temperature, realize that the water that flows out the hot water valve at first has reached the ideal temperature to save time with avoid causing unnecessary cold water extravagant. The water circulation heating times are indirectly controlled through temperature detection, so that the ideal temperature can be ensured, and resource waste caused by excessive water circulation heating or advanced heating and heat preservation can be avoided.
Description
Technical Field
The utility model relates to a hot water circulating technology field especially relates to a domestic hot water circulating system.
Background
When the traditional water heater is used, a power supply needs to be turned on in advance to heat and preserve heat for a period of time, cold water flows out first when a faucet is boiled, and the water temperature slowly rises along with the time extension to reach an ideal temperature. The time for waiting hot water is wasted for users, and the cold water flowing out and the energy consumed by heating and heat preservation in advance are wasted.
As the base of using such water heaters increases, the total amount of water wasted will also increase substantially. Although the development of water heaters has been improved and the heating time of hot water is shortened gradually to increase efficiency, the methods for shortening the heating time of hot water and saving water by means of water circulation are still less used.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the household hot water circulating system is provided to solve the problem that a long section of cold water is discharged when the traditional water heater is started, and the waste of water and electricity resources can be effectively avoided.
The utility model provides a domestic hot water circulating system, includes water heater 1, 1 bottom both ends of water heater link to each other with water inlet 11 and hot water outlet pipe 8 respectively, water inlet 11 links to each other with circulating pipe 9 through circulating pump 2, be provided with temperature sensor 5 on the hot water outlet pipe 8, circulating pipe 9 and delivery port 10 are connected through three-way reversing valve 3.
Further, a control panel 6 and a hot water valve 4 are arranged on the three-way reversing valve 3.
Further, the hot water valve 4 acts on a temperature sensor 5, the temperature sensor 5 acts on a control board 6, and the control board 6 acts on the three-way reversing valve 3.
Furthermore, the temperature sensor 5 is fixedly installed at one end of the hot water outlet pipe 8 close to the three-way reversing valve 3.
The invention has the beneficial effects that: the utility model discloses can guarantee that a power just can flow out hot water, and under the great environment of the difference in temperature, realize that the water that flows out the hot water valve earlier has reached the ideal temperature to save time with avoid causing unnecessary cold water extravagant. The water circulation heating times are indirectly controlled through temperature detection, so that the ideal temperature can be ensured, and resource waste caused by excessive water circulation heating or advanced heating and heat preservation can be avoided.

In the drawings, elements or portions are not necessarily drawn to scale.
FIG. 1 is a schematic diagram of an architecture according to an embodiment of the present invention;
FIG. 2 is a flow chart of the present invention;
1. a water heater; 2. a circulation pump; 3. a three-way directional valve; 4. a hot water valve; 5. a temperature sensor; 6. a control panel; 7. a cold water inlet pipe; 8. a hot water outlet pipe; 9. a circulating water pipe; 10. a water outlet; 11. a water inlet; 12. firepower gear adjusting button.
Detailed Description
The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.
As shown in fig. 1, a household hot water circulation system comprises a water heater 1, wherein two ends of the bottom of the water heater 1 are respectively connected with a water inlet 11 and a hot water outlet pipe 8, the water inlet 11 is connected with a circulating water pipe 9 through a circulating pump 2, a temperature sensor 5 is arranged on the hot water outlet pipe 8, and the hot water outlet pipe 8, the circulating water pipe 9 and a water outlet 10 are connected through a three-way reversing valve 3. The three-way reversing valve 3 is provided with a control panel 6 and a hot water valve 4. The hot water valve 4 acts on the temperature sensor 5, the temperature sensor 5 acts on the control board 6, and the control board 6 acts on the three-way reversing valve 3. And the temperature sensor 5 is fixedly arranged at one end of the hot water outlet pipe 8 close to the three-way reversing valve 3.
A plurality of heating gears can be adjusted to firepower gear adjustment button 12 on water heater 1, and to take three gears as an example, one gear corresponds minimum heating firepower, and second gear corresponds moderate heating firepower, and third gear corresponds maximum heating firepower, and the user can specifically adjust its heating gear according to the temperature of intaking and the ideal temperature manual regulation who sets for.
As shown in fig. 1 and fig. 2, the working principle of the present invention is,
the user turns on the power, sets for ideal temperature through hot water valve 4, and firepower gear adjustment button 12 of water heater 1 is in acquiescence gear, and cold water gets into water heater 1 through water inlet 11 and heats, and the rivers that pass through the heating flow into hot water outlet pipe 8.
The temperature sensor 5 monitors the water temperature of the hot water outlet pipe 8, and when the water temperature reaches a set temperature, the control panel 6 controls the three-way reversing valve 3 to be communicated with the water outlet pipe 10; when the water temperature does not reach the set temperature, the control panel 6 controls the three-way reversing valve to be communicated with the circulating water pipe 9, water flows into the cold water inlet pipe 7 through the circulating water pipe 9, and is pumped into the water heater 1 by the circulating pump 2 to be heated again until the water temperature reaches the set temperature.
The circulation frequency of water is determined by the ideal temperature set by the hot water valve 4 and the firepower gear of the water heater 1, and when the ideal temperature set by the hot water valve 4 is lower and the firepower gear of the water heater 1 is higher, the circulation frequency of water is less; when the ideal temperature set by the hot water valve 4 is higher and the firepower gear of the water heater 1 is lower, the water circulation times are more.
The foregoing is illustrative of embodiments of the present invention, and it is to be understood that the invention is not limited to the precise form disclosed herein and that the invention is not to be considered as limited to the exclusion of other embodiments, and that it may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the concept as described herein, commensurate with the above teachings, or the skill or knowledge of the relevant art. But that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention, which is to be limited only by the claims appended hereto.
