The present embodiment additionally provides a kind of gas heater, and it includes above-mentioned combustion gas water circulation systems, because it includes combustions
The all technical features of the air water circulatory system, therefore, gas heater also have whole technical effects of combustion gas water circulation system.
Embodiment two:
Embodiment three is the further improvement of embodiment two.In embodiment two, if gas heater open twice time interval compared with
It is short, hot water when having last time unlatching is retained after second is opened, in gas heat-exchanger 1,.Water temperature at hot water outlet 102 meets
Set temperature, but be opened into steady operation for the second time and can equally continue for some time, it is hot in gas heat-exchanger 1 in the period
After water flow is complete, cold water, but the subsequent cold water that can also have a period of time can be also flowed out.Temperature sensor 11 detects that water temperature changes
Afterwards, controller 12 can open the closed cycle in embodiment two, until the water temperature of hot water outlet 102 reaches set temperature.This
Sample opens tap, has flowed one section of hot water and just stopped to bad usage experience is brought with water end (W.E.), crosses one end time (water heater
Start to stable state time, 5 ~ 10 seconds) after just will continue to out hot water.Embodiment three is to this further improvement, gas and hot water
Device open twice time interval it is shorter in the case where, it is uninterrupted when hot water out.
In the present embodiment, only introduce and two difference of embodiment:
Water tank 2 is vertically arranged, and the cooling water inlet 101 is set to the top or top of the water tank 2, the cold water pipe 3 and institute
The junction for stating water tank 2 is located at the lower part or bottom of the water tank 2, it is preferable that the cooling water inlet 101 is set to the water tank
2 top, the cold water pipe 3 are located at the bottom of the water tank with the junction of the water tank 2.
Since hot water can float on cold water top, so, start gap twice, the hot water in water tank 2 can retain, Bu Huishou
Cold water influences in cold water pipe 3；After second starts, after cold water enters water tank 2, the hot water caught up in water tank 2 is pushed away from the bottom to top, makes heat
Water first flows into gas heat-exchanger 1, and after water heater enters stable state, cold water initially enters gas heat-exchanger 1, is heated to setting
It is flowed out after determining temperature by hot water outlet 102.Therefore, start gap twice, what hot water outlet 102 flowed out is hot water, controller
12 will not open the closed cycle in embodiment two, be lasting with the hot water of water spot.
Start to guarantee that the hot water amount in water tank 2 reaches water heater to the water consumption of stable state, the volume of water tank 2 is big as far as possible
Some, the volume of the water tank 2 is more than or equal to the gas heat-exchanger 1 by opening the water consumption until steady operation.
To avoid in closed cycle, the impact force for the water that water pump 7 pumps out damages gas heat-exchanger 1, meanwhile, also avoid second
After secondary starting, cold water, which enters, occurs convection current or mixing in water tank 2, labyrinth apparatus will be arranged in water tank 2, the labyrinth apparatus is by cold water
It is run by bottom to top along zigzag path, specifically, as shown in figure 4, multiple partitions 201 are arranged in the inner sidewall of the water tank 2,
The distribution of 201 vertical direction of partition described in muti-piece mutually leads two pieces of partitions 201 to be individually fixed in two sides and the friendship of the water tank 2
Mistake setting mutually leads between two pieces of partitions 201 and forms water stream channel.
The scope of protection of the present invention is not limited to this.Those skilled in the art are made equivalent on the basis of the present invention
Substitution or transformation, it is within the scope of the present invention.Protection scope of the present invention is subject to claims.
