Description

An automatic water-saving and energy-saving water heater

technical field

The utility model relates to a water heater, in particular to an automatic water-saving and energy-saving water heater.

Background technique

my country is a country with severe drought and water shortage. The crisis of water scarcity is exacerbated by the limited availability of fresh water resources, water waste, pollution, climate warming, and decreased precipitation. According to international standards, per capita water resources are less than 3,000 cubic meters for mild water shortage, less than 2,000 cubic meters for moderate water shortage, less than 1,000 cubic meters for severe water shortage, and less than 500 cubic meters for extreme water shortage. As such, there are currently 16 provinces in my country that are severely short of water, and 6 provinces that are extremely short of water; more than 400 of the more than 600 cities in the country are "seriously short of water" and "water short".

When we take a bath every day, we always have to wait for a while after turning on the shower nozzle, and we can take a bath after the cold water runs out. And this phenomenon is more serious in hotels, because the hotel uses a common heater, and then distributes hot water to each room, the required pipeline is longer, and the time for water to go in the pipeline is longer, so we To wait more time. And in this process, more precious water resources are wasted in vain. And after the bath is finished and the tap is turned off, there are still many remaining hot water in the pipeline that have not been fully used, so they stay in the pipeline, and a large amount of heat will be lost, which is a big waste of energy during the use of the water heater.

Utility model content

In order to solve the above technical problems, the utility model provides an automatic water-saving and energy-saving water heater with simple structure and convenient operation, which can effectively solve the problem of wasting cold water before the water heater is used and the heat loss of hot water in the pipeline after use.

The technical scheme adopted by the utility model is: an automatic water-saving and energy-saving water heater, including a water heater, an auxiliary water tank, a water inlet pipe and a tap water pipe; sensor; the water heater communicates with the auxiliary water tank through the hot water pipe, the hot water pipe is provided with a water outlet, and the water outlet is provided with a temperature sensor; the auxiliary water tank is communicated with the tap water pipe.

In the above-mentioned automatic water-saving and energy-saving water heater, the auxiliary water tank is provided with an air outlet, and the air outlet is provided with a normally closed solenoid valve.

In the above-mentioned automatic water-saving and energy-saving water heater, the water outlet is provided with a normally open solenoid valve.

In the above-mentioned automatic water-saving and energy-saving water heater, the water inlet pipe communicates with the hot water pipe through the return pipe; The hot water pipe connection is located between the water outlet and the water heater.

Compared with the prior art, the beneficial effects of the utility model are:

Before using the hot water, the cold water in the pipeline of the utility model is discharged into the auxiliary water tank of the cold water pipeline in advance, and when the water temperature at the temperature sensor at the front end of the faucet is higher than the set temperature, the hot water pipe is turned on to release the hot water, thereby achieving The purpose of saving cold water; when the hot water is used up, just press a specific switch, there will be cold water to drive the hot water in the water pipe back to the water heater tank through the return pipe, and release the warm water below the set temperature before it comes out , disconnect the water flow.

The utility model uses the water pressure provided by the water heater tank as the power in advance through the opening and closing combination of each electromagnetic valve, and discharges the cold water into the auxiliary water tank without wasting the cold water before the hot water flows out; moreover, after the water heater is used, The utility model uses the water pressure of the water pipe as the power, and uses the cold water to drive the hot water back to the water heater; the utility model successfully solves the problem of wasting cold water before the water heater is used and the heat loss of the hot water in the pipeline after use. The utility model also has the advantages of simple structure and convenient operation.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, the utility model includes a water heater 7, an auxiliary water tank 8, a water inlet pipe 9 and a tap water pipe 10; the water inlet pipe 9 is connected to the water heater 7, and the water inlet pipe 9 is provided with a normally open solenoid valve 1 and a temperature sensor 5. The temperature sensor 5 is located between the normally open solenoid valve 1 and the water heater 7 . The water heater 7 communicates with the auxiliary water tank 8 through a hot water pipe 14, the hot water pipe 14 is provided with a water outlet 11, and the water outlet 11 is provided with a temperature sensor 6, a normally open solenoid valve 3 and a water tap. The water inlet pipe 9 communicates with the hot water pipe 14 through the return water pipe 12; Between the water outlet 11 and the water heater 7. The auxiliary water tank 8 is communicated with the tap water pipe 10, the auxiliary water tank 8 is provided with an air outlet 13, and the air outlet 13 is provided with a normally closed solenoid valve 4.

Before using the hot water, the water heater 7 is connected to the power supply, and the start button on the water heater 7 is pressed. Now open the water tap at the water outlet 11, but because the normally open solenoid valve 3 at the water outlet 11 is in a closed state, no water will flow out. First, the temperature sensor 6 detects the water temperature. When the water temperature is lower than the set temperature, the normally closed solenoid valve 2 and the normally open solenoid valve 3 are closed, the normally open solenoid valve 1 and the normally closed solenoid valve 4 are opened, and the cold water flows to the faucet, but due to the normally open solenoid valve Valve 3 is closed, cold water will flow into the auxiliary water tank; when the temperature is higher than the set water temperature, close normally closed solenoid valve 2, normally closed solenoid valve 4, open normally open solenoid valve 1, normally open solenoid valve 3, at this time After the hot water that water heater 7 flows out mixes with the cold water that flows out in auxiliary water tank 8, flow out faucet.

After using the hot water, press the shutdown button of the water heater 7 to start the hot water energy saving program, immediately close the normally open solenoid valve 3, stop the water from the faucet, and the temperature sensor 5 starts to detect the water temperature, when the water temperature is higher than the set value, close the normally open Solenoid valve 1, normally open solenoid valve 3 and normally closed solenoid valve 4, take the water pressure in the water pipe 10 as power, drive the hot water through the cold water in the water pipe 10, and make the hot water return to the water heater 7 through the return pipe. When the water temperature is lower than the set temperature, the normally closed solenoid valve 2, the normally open solenoid valve 3 and the normally closed solenoid valve 4 are in the closed state, and the normally open solenoid valve 1 is in the open state. At this time, the water tap should be turned off, and then the water heater should be disconnected from the power supply.
