Abstract
The utility model discloses a gas water heater with a water-saving function, which comprises an outer cover, an exhaust system, a heat exchanger and a fuel gas system, wherein the heat exchanger is connected with a water inlet pipe and a water outlet pipe. The gas water heater with the water-saving function is characterized in that the water outlet pipe is a double-layer concentric pipe, an inner-layer pipeline inlet and outer-layer pipeline outlet are arranged at the position of an inlet of the water outlet pipe, the inner-layer pipeline inlet of the water outlet pipe is connected with a hot-water outlet of the heat exchanger, the outer-layer pipeline outlet of the water outlet pipe is connected with a cold-water inlet of the heat exchanger, a first thermal induction valve is arranged at the tail end of the water outlet pipe, and a second thermal induction valve is arranged on the inner-layer pipeline wall of the front portion of the first thermal induction valve. The gas water heater with the water-saving function can effectively prevent water resource from being wasted, is simple to implement and has low cost.
Description
Technical field
The utility model relates to a kind of water heater, especially a kind of gas heater.
Background technology
Gas heater is a kind of equipment that present family generally uses, and has the characteristics such as cost is low, heating is fast.But for the purpose of safety, gas heater tends to be installed on the outside, bathroom, and its pipeline is received the bathroom a segment distance, adds that the water heater heating needs the regular hour, when therefore using, always will flow out a lot of cold water at every turn, then could flow out hot water.So just caused the significant wastage of water resource.
The utility model content
The purpose of this utility model is to provide a kind of gas heater with water-saving function.
to achieve these goals, by the following technical solutions: a kind of gas heater with water-saving function, described gas heater comprises outer cover, gas extraction system, heat exchanger and gas burning system, be connected with water inlet pipe and outlet pipe on heat exchanger, it is characterized in that: described outlet pipe is double-deck concentric tube, the porch of outlet pipe is provided with inner layer pipe entrance and outer layer pipe outlet, wherein outlet pipe inner layer pipe entrance connects the hot water outlet of heat exchanger, the outlet of outlet pipe outer layer pipe connects the cold water inlet of heat exchanger, end at outlet pipe is provided with the first thermoinduction valve, be provided with the second thermoinduction valve on the anterior inner layer pipe wall of the first thermoinduction valve, when the water temperature in inner layer pipe does not reach assigned temperature, the first thermoinduction valve closing, the second thermoinduction valve opening, water in inner layer pipe is owing to being subject to stopping of the first thermoinduction valve, flow into outer layer pipe from the second thermoinduction valve, be back to and re-start heating in heat exchanger, when the water temperature in inner layer pipe reaches assigned temperature, the first thermoinduction valve opening, the second thermoinduction valve closing, the water in inner layer pipe flows out from the outlet pipe end.
In order to solve in use of short duration the stopping of fuel gas buring, described gas heater inside also comprises the hot water storage silo, and the entrance of hot water storage silo is connected with the hot water outlet of heat exchanger, and the outlet of hot water storage silo is connected with the inner layer pipe entrance of outlet pipe.
The utility model is transformed on conventional water heaters, outlet pipe adopts double-deck concentric tube, during use, when cold water flows out from the inner layer pipe of outlet pipe, owing to having the delivery port that is communicated with outer layer pipe on inner layer pipe, therefore cold water fails to be convened for lack of a quorum and is left to outer layer pipe by this delivery port, then heats in the circular flow recovery tank.Only have after the water in pipeline reaches uniform temperature, the thermoinduction valve on delivery port can be closed by nature, and the current of this moment not recirculation flow return, but directly outwards export from the interface of outlet pipe.Such structure has effectively been avoided the waste of water resource, realizes that simply cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the partial enlarged drawing of A in Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As depicted in figs. 1 and 2, a kind of gas heater with water-saving function comprises outer cover 1, is disposed with gas extraction system 2 in outer cover 1, heat exchanger 3, combustion system 4, ignition system 5, air blast 6, gas burning system 7.Be provided with water inlet pipe 10 and outlet pipe 8 on heat exchanger 3.Water inlet pipe 10 is double-deck concentric tube, has the delivery port that is communicated with outer layer pipe on its inner layer pipe, is provided with the thermoinduction valve on this delivery port.Also be respectively arranged with water inlet pipe interface 11 and outlet pipe interface 9 on water inlet pipe 10 and outlet pipe 8.Be connected with air inlet pipe 12 on gas burning system 7, also have air inlet pipe interface 13 on air inlet pipe 12.
When water heater working, the water in water tank flows out from outlet pipe.Because outlet pipe has adopted double-deck concentric tube structure, therefore, water can flow out by the inner layer pipe of double-deck concentric tube.When flowing to the delivery port position of inner layer pipe, if the water temperature of this moment does not reach the predetermined temperature of thermoinduction valve, this moment the first thermoinduction valve closing, the second thermoinduction valve can be opened always, make water enter outer layer pipe by delivery port, then circular flow is got back in water tank.
When water heater is heated to a certain degree, when the water temperature that flows out this moment reaches predetermined temperature, the second thermoinduction valve meeting autoshutdown on the outlet pipe outer layer pipe, the hot water of this moment can't flow back to by outer layer pipe again, and can only outwards export by the first thermoinduction valve of outlet pipe, thereby effectively avoided the waste of water resource.
Of the present utility model simple in structure, be easy to realize, cost is low, and has effectively realized water-saving function, therefore has good practical value.
