Description

A kind of gas heater
Technical field
The utility model relates to technical field of water heaters, is specifically related to a kind of gas heater.
Background technology
The gas heater of prior art can not multichannel supply water, and temperature incubation function is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of gas heater, and it can realize multichannel and supply water and temperature incubation function.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises heat exchanger, burner, smoke exhaust pipe, temp probe, tandem thermostatic tank, second return pipe, back water pump, backwater is popped one's head in, backwater switch valve, water flow switch, first return pipe, heat exchanger is connected with tandem thermostatic tank, set temperature probe in tandem thermostatic tank, Gas Pipe is connected with burner, the top of burner is provided with heat exchanger, heat exchanger is provided with smoke exhaust pipe, cold water pipe and back water pump, backwater probe connects, back water pump is connected with water flow switch, water flow switch is connected with heat exchanger, backwater probe and backwater switch valve, second return pipe connects, backwater switch valve is connected with the first return pipe, first return pipe and tandem thermostatic tank, outlet pipe connects.
During the utility model operation, hot water tap opens, and cold water enters, and water flow switch closes, and when water tank temperature does not reach setting value, back water pump starts, and water flow switch closes, and by the second return pipe backwater to heat exchanger, burner is lighted a fire, and realizes temperature incubation function; When water tank temperature does not reach setting value, back water pump starts, and during without backwater tube connector, backwater switch valve should be opened, water flow switch closes, by the first return pipe backwater to heat exchanger, if water tank temperature is lower than design temperature, burner igniting heating, if water tank temperature is not less than design temperature, back water pump starts, and water flow switch closes, but does not start heating function.
The beneficial effect that the utility model produces: multichannel can be realized and supply water, and there is constant temperature, instant-heating, trigger backwater, the functions such as temperature backwater.
Accompanying drawing illustrates:
Fig. 1 is the utility model structure chart.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with the drawings and the specific embodiments, the utility model is further elaborated.Should be appreciated that detailed description of the invention described herein only in order to explain the utility model, and be not used in restriction the utility model.
Referring to Fig. 1, this detailed description of the invention adopts following technical scheme: it comprises heat exchanger 5, burner 6, smoke exhaust pipe 7, temp probe 8, tandem thermostatic tank 9, second return pipe 11, back water pump 1, check valve 2, backwater probe 12, backwater switch valve 3, water flow switch 4, first return pipe 10, heat exchanger 5 is connected with tandem thermostatic tank 9, set temperature probe 8 in tandem thermostatic tank 9, Gas Pipe is connected with burner 6, the top of burner 6 is provided with heat exchanger 5, heat exchanger 5 is provided with smoke exhaust pipe 7, cold water pipe and back water pump 1, backwater probe 2 connects, back water pump 1 is connected with water flow switch 4, water flow switch 4 is connected with heat exchanger 5, backwater probe 12 and backwater switch valve 3, second return pipe 11 connects, backwater switch valve 3 is connected with the first return pipe 10, first return pipe 10 and tandem thermostatic tank 9, outlet pipe connects.
When this detailed description of the invention is implemented, hot water tap opens, and cold water enters, water flow switch 4 closes, and when water tank temperature does not reach setting value, back water pump 1 starts, water flow switch 4 closes, and by the second return pipe 11 backwater to heat exchanger 5, burner 6 is lighted a fire, realize temperature incubation function, when without return pipe, when water tank temperature does not reach setting value, back water pump 1 starts, and backwater switch valve 3 is opened, and water flow switch 4 closes, by the first return pipe 10 backwater to heat exchanger 5, burner 6 is lighted a fire and is heated.
The beneficial effect that this detailed description of the invention produces: multichannel can be realized and supply water, and there is constant temperature, instant-heating, trigger backwater, the functions such as temperature backwater.
The above is only in order to illustrate the technical solution of the utility model and unrestricted, other amendment that those of ordinary skill in the art make the technical solution of the utility model or equivalently to replace, only otherwise depart from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of right of the present utility model.
