Description

Dual-purpose water heater

The dual-purpose water heater of the utility model, it relates to a kind of water heater that utilizes central heating.

Existing market is sold and the electric heater and the gas water heater of family's use, its complex structure, function singleness, price height, needs that the special messenger installs, personal injury takes place easily in improper use.In addition, at present city, rural households and unit have generally used furnace and central heating system, and its weak point also is a function singleness, can only heating, and can not make full use of the usefulness that its hot water or hot gas carry out other daily lifes.

For overcoming the weak point that above-mentioned prior art exists, the utility model provides a kind of hot water of heating system or dual-purpose water heater that hot gas heats bath water of utilizing.

The purpose of this utility model is achieved in that the dual-purpose water heater that casing and coil pipe are formed, tank wall is a waveform before and after it, casing one side connects the water inlet pipe mouth and the backwater mouth of pipe, spiral helicine coil pipe is set in the case, its lower end is connected with the cold water mouth of pipe, the upper end is communicated with hot-water line, and hot-water line is provided with control valve, hot-water line one end installing shower nozzle or tap.

Description of drawings is as follows:

Fig. 1 is the external structure schematic diagram of dual-purpose water heater

Fig. 2 is dual-purpose heater box's internal structure schematic diagram

Fig. 3 is the right side view of Fig. 2;

Fig. 4 is the cross sectional view of casing and coil pipe
