Abstract
The utility model relates to a gas water heater of which the water temperature can be set arbitrarily by a user, and the water temperature is not influenced by the water flow variation, wherein, a full amount valve and a surplus amount valve pipe line are connected in parallel, and are connected with a spraying nozzle pipe line. A flow sensor, a heat exchanger, a buffer and a water valve pipe line are connected in series, and a thermoregulator is respectively electrically connected with a relay J1, a thermostat and a probe. A contact j 1 is electrically connected with the full amount valve. After the thermoregulator makes the water temperature signal inputted by the probe compare with the temperature value set by the thermostat, the circuit of the relay J1 can be switched to, and thus the full amount valve can be opened and closed from time to restrict the wave amplitude of the water temperature. After the wave amplitude is sharply reduced by the buffer, the water is the constant-temperature hot water selected by the user.
Description
What technical field the utility model was related is a kind of gas appliance.
The existing gas heater of background technology all is to utilize the flow of water under the constant situation of firepower and the principle that temperature is inversely proportional to, and adjusts water temperature.The water heater user adjusts flow by water valve, thereby obtains own needed water temperature.Use the gas heater of this temperature adjustment principle, certainly existing following defective:
One, because current are slightly greatly then cold, slightly little then boiling hot, so need turning water valve repeatedly, the user adjusts the water yield, just can obtain being suitable for the water temperature of oneself.Therefore temperature adjustment bothers.
Two, the user can't handle the combustion gas air valve in the bathroom, so under the constant situation of discharge, water temperature does not have adjustability.
Three, the size of current can not arbitrarily change, otherwise the water temperature that mixes up also can become thereupon.So the water yield does not have adjustability.
Four, tap water pressure or gaseous-pressure such as instability promptly can cause the disturbance of current or air-flow, water temperature also will the time when high the lowland change.Therefore water temperature stability is poor.
Five, the igniting of gas heater must have certain gas quantity (being minimum working flow).In the time in midsummer, the heat energy that this minimum combustion gas working flow is produced also often can make water temperature rise to the height that bath person is difficult to accept.Therefore summer poor practicability.
Six, in the process of using, if water valve cuts out suspend to supply water, in several minutes clock times, though the closing and extinguish automatically with water valve of the fire in the burner hearth, but because the thermal inertia effect, the waste heat of heat exchanger can be heated to the water that is trapped in the pipeline more than 80 degree.Open water valve this moment again, outflow must be people's the boiling hot water of causing injury.
Summary of the invention is in order to solve the problem of existing gas heater water temperature stability difference, the utility model provides a kind of gas heater, the water temperature of this water heater can be stabilized on any temperature value of setting of user, be not subjected to influencing of tap water pressure or gaseous-pressure fluctuation, also be not subjected to influencing of discharge variation, and the user also can change the temperature value of having set arbitrarily in the process of taking a shower.
The technical scheme that the utility model adopted is as follows: air path part comprises full dose valve, surplus valve, nozzle, burner and burner hearth.Burner hearth is positioned on the nozzle.Burner is between nozzle and burner hearth, and burner hearth is stretched in the upper end.Heat exchanger is positioned on the burner hearth.Full dose valve and surplus valve are magnetic valve (energising is opened, and outage is closed), two valve pipeline parallel connections, and back in parallel is gone up and is connected with the nozzle pipeline, is connected with fuel gas inlet place pipeline down.The water route part comprises flow sensor, heat exchanger, buffer, water valve, shower nozzle, check valve and water pump.Flow sensor, heat exchanger, buffer, water valve and the series connection of shower nozzle pipeline.The flow sensor lower end is a cold water inlet.The check valve water side is connected with water pump water inlet end pipeline.The water pump water outlet end is connected with the pipeline that flow sensor leads to heat exchanger.The check valve water intake end is connected with the pipeline that buffer leads to water valve.Circuit part comprises power supply, full dose valve, surplus valve, temperature controller, probe, incubator, water pump, ignition controller, inductive needle, igniting pin, flow sensor, on-off circuit, temperature-sensitive switch, preheating switch, two diodes and four relays.Probe, incubator, relay J

When opening water valve, flow sensor just can be to the on-off circuit and the temperature controller output signal of telecommunication.Input just can turn-on power and relay J as long as on-off circuit has the signal of telecommunication
2Circuit, so J
2Must be electric, contact j
2Closure must be established full dose valve and surplus valve by cable and is opened, and imports combustion gas by nozzle and burner to burner hearth.Meanwhile, ignition controller is also because of j
2Closure and electric work, and by igniting pin discharge igniting in burner hearth, even if stove fire with the burning of full dose firepower, water temperature rises.(stove fire is in case burning, and inductive needle is about to be heated and the signal of telecommunication that produces input ignition controller, and order igniting pin stops discharge).When the water temperature in the buffer rises to the operating temperature of temperature-sensitive switch, temperature-sensitive switch closure, relay J

3-1Closure, J
3Self-insurance.At this moment temperature controller is also because of j
3-1Closure and be in the energising duty, receive and handle the signal that probe and incubator are imported.When the probe measured temperature surpassed the analog value of incubator established temperature, temperature controller was just to relay J
1Power supply makes its contact j
1Disconnect, so the full dose valve cuts out, the burner hearth firepower falls sharply.This moment, the surplus valve was still opened, but the gas quantity that is provided only can be kept the burning of stove fire, so water temperature descends.When probe place water temperature was brought down below the analog value of incubator established temperature, temperature controller just stopped to relay J
1Power supply, contact j
1Closure, so the full dose opening of valves, burner hearth recovers the full dose firepower, water temperature rises once more.So go round and begin again, the wave amplitude of heat exchanger leaving water temperature is limited in certain scope.Buffer has certain capacity, can dwindle the fluctuation of water temperature significantly.From the hot water that still has the uniform temperature fluctuation of heat exchanger output, its wave amplitude falls sharply once again after the buffer of flowing through, and it is little of the imperceptible constant-temperature hot water of bath person to be temperature fluctuation after shower nozzle flows out.Flow sensor and temperature controller have been formed temperature-compensation circuit.If there is not this circuit, water temperature still can decrease because of the increase of discharge, raise to some extent with the minimizing of discharge, although amplitude of variation little (temperature difference of minimum discharge and full flow is 3 degree), to constant temperature effect also influence to some extent.The principle of temperature-compensation circuit is: when flow equals full flow, the electrical signal intensity of flow sensor input temperature controller remains unchanged the desired temperature of incubator input temperature controller, in a single day flow diminishes, the electrical signal intensity of flow sensor input temperature controller will correspondingly die down, make corresponding the diminishing of desired temperature of input temperature controller, (being equivalent to former desired temperature is done corresponding downward modulation), so just offset the temperature rise that diminishes and produce because of discharge.Opening before water valve uses this water heater, if cold water in the buffer in order to save the combustion G﹠W, just needs carry out preheating to the water in buffer and the water system, (particularly cold season) earlier.Click preheating switch, relay J
