Abstract

The utility model relates to a water saving device for a water heater, which comprises a water outlet pipe, wherein two water outlet valves close to a water outlet are arranged on the water outlet pipe; a water return pipeline opening leading to a water tank is arranged on the water outlet pipe between the two water outlet valves; and a one-way valve and a temperature gauge are arranged in the position close to the water outlet pipe on the water return pipeline. When the water saving device is used, one of the water outlet valves close to the water tank on the water outlet pipe are opened firstly, the initial cold water in the water outlet pipe bursts through the one-way valve arranged on the water return pipeline and then flows back to the water tank; when the temperature on the temperature gauge is displayed as the temperature of usable hot water, the other water outlet valve on the water outlet pipe is opened, and then hot water flows out; water in the water return pipeline cannot flow backwards under the action of the one-way valve; meanwhile, the water tank is higher, and the water outlet of the water outlet pipe is lower, so that hot water cannot flow backwards to the water tank again; and after use, the water outlet valve that is firstly opened is closed at first, and then the water outlet valve that is secondly opened is closed. The water saving device has the advantages of simple structure, convenient use, energy conservation and the like.

Description

Water-saving device of water heater

Technical field

The utility model relates to a kind of water-saving device of water heater.

Background technology

China is the country of a water resource famine, and existing water heater all needs to bleed off a part of cold water earlier in use, has caused the waste of water resource, and is also inconvenient during use, and present water heater does not also have a kind of settling mode.

Summary of the invention

The utility model is for overcoming above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to use, water-saving device of water heater of economizing on resources is provided.

The purpose of this utility model is to adopt following technical proposals to realize:

A kind of water-saving device of water heater, it comprises outlet pipe, on outlet pipe, two outlet valves are set, on the outlet pipe between two outlet valves, draw a water return pipeline towards water tank, be provided with a check valve and a thermometer near the outlet pipe place on the water return pipeline near the delivery port place.

During use, open the outlet valve of close water tank on the outlet pipe earlier, then the cold water of beginning part is washed open in the check valve reflow tank on the water return pipeline in the outlet conduit, when the temperature on the thermometer is shown as the available heat coolant-temperature gage, open another outlet valve on the outlet pipe, then hot water flows out, because the water in the effect return pipe of check valve can not flow backwards, simultaneously because water tank is higher, the delivery port of outlet pipe is lower, and hot water can not flow backwards in water tank again, finishes using, shut the outlet valve that first is opened earlier, close second outlet valve again.The utlity model has advantages such as simple in structure, easy to use, energy savings.

Description of drawings

Fig. 1 is the utility model structural representation;

Wherein 1. outlet pipes, 2. outlet valve, 3. check valve, 4. thermometer, 5. water return pipeline.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Among Fig. 1, on outlet pipe 1, two outlet valves 2 are set, on the outlet pipe 1 between two outlet valves 2, draw a water return pipeline 5 towards water tank, be provided with a check valve 3 and a thermometer 4 near outlet pipe 1 place on the water return pipeline 5 near the delivery port place.During use, open the outlet valve 2 of close water tank on the outlet pipe 1 earlier, then the cold water of beginning part is washed open in check valve 3 reflow tanks on the water return pipeline 5 in the outlet pipe 1, when the temperature on the thermometer 4 is shown as the available heat coolant-temperature gage, open another outlet valve 2 on the outlet pipe 1, then hot water flows out, because the water in the effect water return pipeline 5 of check valve 3 can not flow backwards, simultaneously because water tank is higher, the delivery port of outlet pipe 1 is lower, and hot water can not flow backwards in water tank again, finishes using, shut the outlet valve that first is opened earlier, close second outlet valve again.

Claims

1. water-saving device of water heater, it comprises outlet pipe, it is characterized in that: on outlet pipe, two outlet valves are set, on the outlet pipe between two outlet valves, draw a water return pipeline towards water tank, be provided with a check valve and a thermometer near the outlet pipe place on the water return pipeline near the delivery port place.
