A kind of energy-conservation, high-efficiency gas burning water heater
Technical field:
The present invention relates to a kind of gas burning water heater.
Background technology:
Existing gas burning water heater by fire row, be positioned at water tank on the fire row, be positioned at water tank be connected with fire row the flue gas coil pipe, export the smoke exhaust fan that is connected with the flue gas coil pipe, the boiled water tank that has depotition cock that is connected with water tank constitutes, for energy-conservation, what have is provided with heat-insulation layer all around at water tank.This kind gas burning water heater is owing to have only the flue gas coil pipe in the water tank that the water in the water tank is heated, and water is heated to boiling water from normal temperature, the temperature difference is very big, the heat exchange area of flue gas coil pipe is limited, therefore, even around water tank, heat-insulation layer is set, can not increases the speed of boiling water effectively.
Summary of the invention:
Goal of the invention of the present invention is to provide a kind of energy-conservation, high-efficiency gas burning water heater that can improve boiling water speed.
The present invention realizes like this, comprise fire row, be positioned at the water tank on the fire row, be positioned at water tank be connected with fire row the flue gas coil pipe, be positioned at the smoke exhaust fan that is connected with the outlet of flue gas coil pipe above the water tank, the boiled water tank that has depotition cock that is connected with water tank, its special feature is in the both sides of water tank and the back is provided with the interlayer water tank, boiled water tank is connected the front of water tank, end face at water tank is provided with the interlayer boiled water tank, interlayer boiled water tank and boiled water tank are interconnected, arranged outside at the interlayer water tank has the cold water storage cistern that has ball-cock assembly, cold water storage cistern is connected with the interlayer water tank, and the interlayer water tank is connected with water tank.During work, ball-cock assembly links to each other with running water pipe, the water level of ball-cock assembly control cold water storage cistern, the water of cold water storage cistern is introduced into the interlayer water tank, and then enter water tank, enter boiled water tank by the interlayer boiled water tank at last, the water in the water tank is heated into boiling water by the flue gas coil pipe, in the process that boils water, the heat energy that is scattered and disappeared around the water tank is absorbed by the water in the interlayer water tank, make the water in the interlayer water tank obtain preheating, risen to than higher temperature, like this before entering water tank again, after entering water tank, need not be how long, water just can be by boiled, thereby promoted the speed of heating up water significantly, at the top of water tank the interlayer boiled water tank is set, and boiled water tank is arranged on the front of water tank, makes the water in the boiled water tank can continue the acquisition heat energy that water tank scattered and disappeared, the temperature of the water of assurance boiled water tank continues to maintain higher level.
The present invention compared with the prior art, because at the arranged outside interlayer water tank of water tank and boiled water tank is arranged on the front of water tank, therefore, has the advantage that the temperature that can improve water boiling water speed, compact conformation, boiled water tank continues to maintain higher level.

Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the present invention is described in further detail:
As shown in the figure, the present invention includes fire row 1, be positioned at the water tank 2 on the fire row 1, be positioned at water tank 2 be connected with fire row 1 flue gas coil pipe 3, be positioned at the smoke exhaust fan 4 that is connected with flue gas coil pipe 3 outlet 3a above the water tank 2, the boiled water tank that has depotition cock 56 that is connected with water tank 2, its special feature is to be provided with interlayer water tank 7 at the both sides of water tank 2 2a and back 2b, boiled water tank 6 is connected the front 2c of water tank 2, end face 2d at water tank 2 is provided with interlayer boiled water tank 8, interlayer boiled water tank 8 is interconnected with boiled water tank 7, arranged outside at interlayer water tank 7 has the cold water storage cistern 10 that has ball-cock assembly 9, cold water storage cistern 10 is connected with interlayer water tank 7, and interlayer water tank 7 is connected with water tank 2.In order to prevent dissipation of heat energy, be provided with heat-insulation layer 11 at the outer surface of boiled water tank 6 and interlayer boiled water tank 8.In order to guarantee that interlayer boiled water tank 8 keeps containing water, is provided with weir 12 at interlayer boiled water tank 8 and boiled water tank 6 connecting places.In order further to utilize the heat energy of combustion product gases, interlayer water tank 7 will connect the smoke discharging pipe 3b parcel of 4 of flue gas coil pipes 3 outlet 3a and smoke exhaust fans outside the water tank 2.
