Abstract

The utility model provides a thermostatic gas water heater. The water heater is provided with a water mixing chamber which is communicated with a hot water outlet and a constant temperature hot water outlet. The water mixing chamber is connected with a cold water inlet pipe through a cold water storing device. A cold water branch pipe is arranged between the cold water storing device and the cold water inlet pipe. A storing device water outlet pipe is arranged between the cold water storing device and the water mixing chamber. A water hydraulic valve is arranged between the water mixing chamber and the cold water storing device. One switch of the valve is connected with the cold water branch pipe and the other switch is connected with the water outlet pipe of the storing device. The position of the water outlet of the storing device is provided with a non-return valve. The utility model can eliminate the momentary high temperature water in the operating process of the water heater. Thus, the output water temperature can be ensured to be constant fundamentally; the scalding hazard is eliminated thoroughly; the safety of the water heater is raised; the degree of comfort for bathing is raised.

Description

A kind of constant temp gas water heater

Technical field

The utility model relates to a kind of gas heater.

Background technology

Existing gas heater, Temporarily Closed water outlet in using when opening again, can be exported the moment high-temperature water of 200～300ml, generally speaking, this high-temperature water can exceed about 10 ℃ than set water temperature, if former set water temperature is 40 ℃, this moment, water temperature will be more than 50 ℃, for tender and lovely skin, this temperature is enough to cause scald, if by chance reduced water yield when opening water heater again, this temperature can be higher.In use, the user is for fear of being scalded, often take when reopening water heater, to allow the empty stream of hot water a little while, after treating that high-temperature water has been put, begin flushing again, for the user who wipes or from head to foot full soap or body lotion all over the face, particularly in cold weather, give these several seconds the people feel be like a hen on a hot girdle.For fear of this uncomfortable feeling, a lot of people have taked using intermittently, do not close the workmanship method of water heater, when using soap or body lotion, make the empty stream of hot water, and generally speaking, the waste rate of the water and the energy is about 1/3rd.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of moment high-temperature water of eliminating in the water heater use, makes output water temperature can keep substantially invariable constant temp gas water heater.

The technical solution of the utility model is: a kind of constant temp gas water heater, comprise cold water inlet, heater, hot water outlet, and this water heater is provided with a mixing chamber, and hot water outlet is connected with mixing chamber, and mixing chamber is communicated with the constant-temperature hot water outlet.

Feature of the present utility model also is: mixing chamber stores device through a cold water and links to each other with cold water inlet, cold water stores between device and the cold water inlet has cold water to be in charge of, cold water stores the device of storing outlet pipe between device and the mixing chamber, storing at mixing chamber and cold water has a hydraulic valve between the device, one switch of valve connects cold water and is in charge of, another switch connects and stores the device outlet pipe, stores device delivery port place and adorns a non-return valve.

Said cold water stores the structure of device for to adorn a piston spring in storing device, and an end of spring is equipped with the moisture storage capacity adjusting screw(rod), and the other end is fixed in cold water and stores on the piston in the device.

Compared with prior art, the utlity model has following effect:

One, since adopted the water-water jet method to moment high-temperature water neutralize, thoroughly eliminated the danger of scalding, improved the degree of safety of water heater.

Two, because the part that adopts benefit cold water method to meet design requirement is directly introduced in the water-water jet without the running water of heating, thereby the water temperature domain of walker can be controlled at set water temperature ± 1 ℃ of scope in, therefore this variation human body general sensation can improve the comfort level of bathing less than variation.(constant temperature relatively)

Three, because the equilibrium process of whole water temperature all is an Automatic Control, not having increases the many actions and the trouble of adjusting, thereby makes people be happy to close water outlet when using intermittently, thereby has reached the purpose of saving water and energy.

Four, safer, more convenient, more water saving, energy-conservation.

Below in conjunction with accompanying drawing the utility model is described in further detail;

Description of drawings

Fig. 1 is a structural representation of the present utility model; Fig. 2 is hydraulic valve assembling schematic diagram.

The specific embodiment

Among Fig. 1, install one the hot water exit of water heater and have the metal of a constant volume or the mixing chamber 4 that other heat-resisting pressure-resistant materials are made, the spring hydraulic pressure cold water that communicates with cold water inlet 1 and mixing chamber 4 at mixing chamber 4 peripheral hardwares one stores device 9, the Inlet and outlet water that stores device 9 is by hydraulic valve 6 controls, one switch of hydraulic valve 6 connects cold water and is in charge of 8, another switch connects and stores device outlet pipe 7, stores device delivery port place and adorns a non-return valve 5, and non-return valve 5 can prevent that hot water from pouring in down a chimney spring hydraulic pressure cold water and storing in the device 9.2 are the constant-temperature hot water outlet, and 3 is effluent switch, and 12 is heater.Spring hydraulic pressure cold water stores in the device 9, and spring 10 is housed on the piston 11, and the other end of spring 10 is equipped with moisture storage capacity adjusting screw(rod) 15.

Have one to mix water distribution pipe 13 below the hot water primary outlet 14 of water heater in addition, mixing water distribution pipe 13 is the less water pipe of a bore, and its task is preferentially part moment high-temperature water to be transported to mixing chamber 4 nearly exits, increases cold and hot mixed water effect.

Among Fig. 2, piston and spring are arranged in the hydraulic valve 6.When system's hydraulic pressure is high pressure conditions (cold water inlet is opened), spring is compressed into, and opens cold water and is in charge of 8, closes and stores device outlet pipe 7; When system's hydraulic pressure is low-pressure state (cold water inlet is closed), spring ejects, and closes cold water and is in charge of 8, opens and stores device outlet pipe 7.

Its use is: in use, when temporary close effluent switch 3, hydraulic valve 6 is in high pressure conditions, opens cold water when storing device outlet pipe 7 and is in charge of 8 closing, this moment, cold water was under self pressure effect, promoted cold water and stored the piston 11 of device 9 and enter cold water and store device 9.When opening effluent switch 3 once more, hydraulic valve 6 is in low-pressure state, and store device outlet pipe 7 and open this moment, cold water is in charge of 8 and is closed, moment high-temperature water and the cold water that stores in the device 9 of cold water enter mixing chamber 4 simultaneously, and, export from the constant-temperature hot water outlet with after original water in the mixing chamber 4 mix.This moment the fluctuation range of set water temperature of water temperature and former gas heater be no more than ± 1 ℃, reached the effect of constant water temperature.
