Description

Water saving device for domestic gas water heater

technical field

The utility model relates to a water-saving device for a household gas water heater.

Background technique

With the improvement of people's living standards, water heaters have become one of the necessary facilities for people's daily life. However, when the gas water heater is in use, hot water will not flow out immediately after opening the shower valve, but it will take a while until the cold water in the pipe section between the water heater and the faucet flows out before there is hot water. Usually, this part of the water with lower temperature is flowed away in vain, causing a lot of waste. Especially in summer, the frequency of use of water heaters increases, and the cumulative waste is considerable.

For this problem, many scholars have proposed some solutions and designed some water-saving structures. Generally, it can be summarized as follows: 1. Artificially use buckets or basins to catch this part of water and use it in other places; 2. Add power components to the pipeline, and use the return circulation pump to pump this part of cold water back into the water heater for heating. Undoubtedly, these methods have achieved the purpose of saving water to a certain extent, but method 1 is relatively primitive, and the procedure is mechanical, which wastes manpower and material resources; method 2 sets up a power device such as a backflow circulation pump, which requires additional power consumption and increases energy waste. , and the cost is higher.

Contents of the invention

The purpose of the utility model is to provide a water-saving device for a household gas water heater. In order to solve the problems proposed in the background technology, the utility model adopts the following technical solutions:

A water-saving device for a household gas water heater, comprising: a temperature control valve, a water-saving water inlet pipe, a water storage tank, a water outlet pipe, an overflow pipe, and a faucet. Install a temperature control valve on the hot water pipe at the front end of the shower valve; one end of the water-saving water inlet pipe is connected to the temperature control valve, and the other end is connected to the water storage tank; the water storage tank is installed on the indoor toilet tank; the side wall of the water storage tank is provided with an overflow The flow pipe is connected with the toilet water tank; a water outlet pipe is arranged at the bottom of the water storage tank and connected with a water faucet.

The utility model has the following advantages:

1. The utility model does not need to add an additional power system to achieve the purpose of water saving, which can save costs;

2. The utility model has simple structure and convenient installation.

Among them: 1. Temperature control valve, 2. Water-saving inlet pipe, 3. Water storage tank, 4. Outlet pipe, 5. Overflow pipe, 6. Faucet, 7. Toilet water tank, 8. Shower valve, 9. Inlet cold water pipe , 10. Hot water pipe, 11. Shower pipe, 12. Water heater.

Detailed ways

A water-saving device for a household gas water heater, comprising: a temperature control valve 1 , a water-saving inlet pipe 2 , a water storage tank 3 , a water outlet pipe 4 , an overflow pipe 5 , and a faucet 6 . A temperature control valve 1 is installed on the hot water pipe 10 at the front end of the shower valve 8; one end of the water-saving water inlet pipe 2 is connected to the temperature control valve 1, and the other end is connected to the water storage tank 3; the water storage tank 3 is installed on the indoor toilet water tank 7 The side wall of the water storage tank 3 is provided with an overflow pipe 5 connected to the toilet tank 7;

Embodiment: When bathing, just open the shower valve 8, the water flow in the hot water pipe 10 is cold water, at this moment the temperature control valve 1 disconnects the connection of the hot water pipe 10 connected with the shower pipe 11, so that the cold water in the upstream of the temperature control valve 1 It directly flows into the water-saving inlet pipe 2, and then flows into the water storage tank 3; as the water heated by the water heater 12 continuously flows into the hot water pipe 10, when the hot water reaches the temperature control valve 1, the temperature control valve 1 is disconnected from the water-saving inlet. The connection of the water pipe 2 makes the upstream and downstream hot water pipes 10 communicated, and at this moment, the water flowing out of the shower pipe 11 is heated hot water. When the user feels that the temperature is higher in the bathing process, the shower valve 8 can be adjusted to control the outlet water temperature, because the cold water flowing out of the cold water pipe 9 does not pass through the temperature control valve 1 . The water collected in the water storage tank 3 can be discharged through the water outlet pipe 4, and only the water tap 6 installed at the end of the water outlet pipe 4 needs to be opened. If the water yield that water-saving inlet pipe 2 flows in is more, the excess water of water storage tank 3 can flow in the toilet water tank 7 by overflow pipe 5.
