Normal pressure multifunction water-heating stove

Technical field

A kind of the provided sanitary water of hotels and other places and atmospheric hot-water boiler of idle call hot water of being applicable to is provided the utility model.

Background technology

At present, for hotel and leisure place provide the equipment of sanitary water and air-conditioning, general what adopt is band pressure steam boiler or common normal-pressure hot-water boiler or lithium bromide direct combustion machine.Wherein the defective of lithium bromide direct combustion machine is that cost of investment is higher, and the use cost of steam boiler is higher, and common atmospheric hot-water boiler can't be delivered to hot water roof, also can't carry out the air conditioner water circulation.

The utility model content

The technical problems to be solved in the utility model is that the defective at prior art exists provides a kind of improved normal pressure multifunction water-heating stove.This water heater can not only provide health hot water for the hotel, can also provide idle call hot water simultaneously, and one-time investment, and cost is low, and use cost is lower.

Technical solution of the present utility model is that the described this improved hotel that can be provides the normal pressure multifunction water-heating stove of health with hot water and idle call hot water.As shown in Figure 1, have the body of heater 6 of top band chimney interface 1, body of heater 6 peripheries are provided with heat-insulation layer 5, and inner chamber is provided with the inner bag 13 and the support 7 of band end socket 14.The fire door 10 of inner bag 13 extends radially out body of heater 6.Vertical duct is connected to the fire tube 15 that leans on mutually with support 7 on the end socket 14 of inner bag 13.Pipe connects smoke-box 2 between fire tube 15 and the above-mentioned chimney interface 1.2 two ash removing openings 3 of smoke-box extend radially out body of heater 6.On the smoke-box 2 top bodies of heater 6 pressure regulator valve 20 is housed, water inlet 12 and sewage draining exit 11 are equipped with in body of heater 6 belows.Its technical characterstic is that spiraling on the described fire tube 15 is arranged with coil pipe 4.The water inlet 9 and the delivery port 17 of coil pipe 4 extend radially out body of heater 6 respectively.Spiral on the described support 7 and be arranged with coil pipe 16.The water inlet 8 of coil pipe 16 and delivery port 19 also extend radially out body of heater 6 respectively.

Above-mentioned coil pipe 4 replaces the spiral idle call hot water cyclesystem that former water circulation system forms a sealing.Coil pipe 16, links to each other with support 7 in the air-conditioning coil pipe outside as the sanitary water pipe, the water temperature rate of climb in can accelerating to manage.This coil pipe by Outer Tube be connected with user's roof boiler can utilize cold water and the hot water weight difference form water circulation system.

Operation principle of the present utility model is to adopt two groups of threaded spring coil pipes at the atmospheric hot-water furnace interior, one group of confession air conditioning hot circulation usefulness, one group of confession health hot water circulation usefulness.Two groups of coil pipes all are connected with the interior directly heating surface of water heater, utilize the interior hot water of direct radiant heat and stove the heating of the water in two groups of threaded coilers, and two groups of interior water of coil pipe constantly circulate, and in time export furnace heat.Make that the water circulation resistance strengthens in

coil pipe

4,16 pipe because coil pipe is screw-like, thereby heat-exchange surface also increases and has promoted the thermal efficiency.

The beneficial effects of the utility model are: operating cost is low, and thermal efficiency height makes refrigeration and heating effective, energy savings, and more traditional water heater is saved nearly operating cost of 50 percent; Can provide health hot water by big flow, satisfy the demand, its market prospects are very good.
