Abstract
The invention discloses a gas water heater, which can heat the water of heat exchanger and the tube to right temperature to avoid waste. It comprises a gas water heater, wherein, the temperature sensor is mounted on the water tube of heat exchanger; the temperature sensor is connected to the input of temperature controller, while the output is connected to the input of electromagnetic switch valve; said electromagnetic switch valve is mounted on the water inlet tube between the water amount adjust valve and the heat exchanger to form a temperature control electromagnetic switch valve to decide when the water can enter into the heat exchanger. With said invention, the gas water heater can heat the water at the preset temperature, to save water and energy.
Description
Affiliated field:
The present invention relates to gas heater, particularly domestic gas-fired water heater.
Background technology:
Conventional gas heater is after opening water intaking valve, and the room temperature water that has about 5-10 to rise is wasted.Reason is that water heater has a small amount of cold water in the tube connector of bathing place, and approximately less than is one liter; And more chief reason is a thermal energy transfer device in the water heater, and promptly heat exchanger is a temperature-rise period gradually, has only when the burned device of heat exchanger to be heated to when temperature required, just may flow out the hot water of suitable temperature from outlet valve.Therefore, the temperature-rise period gradually of the heat exchanger leaving water temperature that causes gas heater to begin is low and waste.
Number of patent application is 200410017360.9, denomination of invention is the purpose of hot water for " preheating type domestic gas-fired water heater system " can reach the beginning water outlet, it is to constitute autonomous system by additional pipeline, pump, valve etc., flow out again after making mobile beginning water outlet circulation heating, but circulation heat time heating time and not control of temperature to the beginning water outlet of flowing, therefore beginning to discharge water not necessarily is exactly suitable temperature, and the end user need open depotition cock by rule of thumb.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned technology, a kind of gas heater of instant-heating is provided, this water heater can heat the water that retains within it, after this water temperature reaches the temperature controller design temperature, automatically water inlet reaches instant-heating to guarantee the temperature that requires of water outlet, saves water and energy; In the process of water, detection of dynamic, control water temperature.
In order to realize the foregoing invention purpose, technical scheme of the present invention is:
The present invention includes gas heater, temperature sensor is installed on the water pipe of heat exchanger of this gas heater, this temperature sensor is connected with the input of temperature controller, the output of temperature controller is connected with the input of electromagnetism on-off valve, this this electromagnetism on-off valve is installed on the inlet channel between water heater water regulating valve and the heat exchanger, form with the control of the water temperature in heat exchanger electromagnetism on-off valve, when decision cold water enters heat exchanger.
During use, at first open water intaking valve, the hydraulic balance chamber obtains hydraulic pressure at once, and the aqueous vapor interstage valve is opened, and combustion gas enters burner combustion, reheat heat exchanger.But this moment, the electromagnetism on-off valve entered heat exchanger because of normally closed blocking-up cold water, and heated is the stationary water that retains in the heat exchanger.Water temperature is by the temperature sensor continuous detecting, and signal is transferred to temperature controller, when water temperature reaches setting value on the temperature controller, promptly allows the electromagnetism on-off valve open, the heat exchanger heats that allows cold water enter to be preheated, and the beginning water outlet of water side promptly is a hot water.Accompanying drawing 1 is original technical movements flow chart, and the beginning water outlet of water side is a cold water; And accompanying drawing 2 is action flow charts of the present invention, and the beginning water outlet of water side is the suitable hot water that can set arbitrarily.
The present invention compared with prior art has following technique effect:
1. by first preheating heat exchanger, postpone cold water and enter, make this water heater open-and-heating, do not have the waste of water and heat energy, save water and energy.
2. the beginning leaving water temperature can be set arbitrarily on temperature controller, follow-up water temperature is by the original control system control of water heater, follow-up water is lower than beginning water outlet design temperature, then the electromagnetism on-off valve is closed, make the water temperature in the heat exchanger obtain of short duration heating, after reaching the controller set water temperature, allow cold water enter immediately again, to guarantee the temperature that requires of water outlet.Avoid waste.
3. the present invention does not change the original structure and the profile of gas heater substantially, simple installation, and cost is low.

The specific embodiment:
The present invention is on the basis of existing gas heater, temperature sensor is installed in the water pipe of heat exchanger of this gas heater, and with the pipe in water contact or be installed on this water pipe outer surface, or temperature sensor is installed in the water pipe of heat exchanger of this gas heater or the high temperature place on this water pipe outer surface, temperature sensor links to each other with the input of temperature controller, the output of temperature controller is connected with the input of electromagnetism on-off valve, the electromagnetism on-off valve is installed on the inlet channel between water heater water regulating valve and the heat exchanger, form with the control of the water temperature in heat exchanger electromagnetism on-off valve, when decision cold water enters heat exchanger.Between heating pipe's port of export on the heat exchanger and the outlet pipe arrival end bend pipe that communicates is housed.This bend pipe can be U-shaped pipe or inverted-loop tube after installing, and to guarantee in water pipe resident water being arranged, prevents empty the burning.
During use, the temperature value of design temperature controller at first, open outlet valve, drive water valve then into, the hydraulic balance chamber obtains and the equal hydraulic pressure of external water pipe at once, and hydraulic pressure is connected microswitch, open gas valve, starting impulse signal generator, make arresting element igniting, while hydraulic pressure that hydraulic chamber's film is moved to left and open the aqueous vapor interstage valve, combustion gas enters burner combustion by blast tube, the beginning reheat heat exchanger.This moment, cold water did not enter heat exchanger owing to the blocking-up of electromagnetism on-off valve.In the time of heating, temperature sensor begins the resident water water temperature in the continuous detecting heat exchanger, reach set temperature value when detecting water temperature value, by temperature controller the electromagnetism on-off valve is opened, allow cold water enter heat exchanger, because heat exchanger and resident water wherein are heated, so promptly be the hot water of suitable bathing from the water that outlet valve or shower head begin to flow out.In the bathing, when water temperature is lower than setting value, then the electromagnetism on-off valve will be closed in short-term by temperature controller, but keep making aqueous vapor interstage valve be in opening owing to hydraulic pressure is same this moment, burner burns away heat exchanger is heated up, after water temperature reaches setting value, open the electromagnetism on-off valve more automatically, allow cold water enter heat exchanger.Can keep leaving water temperature to be not less than design temperature like this.When finishing bathing, turn off outlet valve.
