Abstract

The utility model discloses a multifunctional water heater which solves the problems that the present water heater has the defects of short hydraulic ducts, uneasy control of the water temperature, lower thermal efficiency, and difficulty of fitting for a plurality of heating sources. The utility model is characterized in that a heating spiral pipe used as a water inlet is communicated with the circular heating water disk welded by an upper and a lower cover plates, a conic water jacket which is communicated with the heating water disk and provided with hydraulic ducts is arranged on the external sides of the spiral pipe and the heating water disk, and a gap passed by the burnt gas is arranged between the heating water disk and the water jacket. The utility model fitting for a plurality of heating sources has the advantages of simple structure, convenient operation, long hydraulic ducts, easy control of the water temperature, and high thermal efficiency.

Description

Multi-functional water-heating unit

The utility model is a kind of multi-functional water heater.

Existing water heater normally adopts coil arrangement, is about to the metal tube bending and makes the single or multiple lift spiral coil, is placed on the stove and accessory and heats; Or adopt stamping-welded structure, be to disclose a kind of " family expenses speed shower device " in the patent application of GG86206439 as notification number, it adopts upper and lower two boards welded structure, stamps out water stream channel on upper cover plate and the lower cover, and is integrally welded then.Above-mentioned two kinds of heaters are because its water stream channel is shorter, and therefore, water temperature is wayward; The heat of stove fire sheds around heater, thereby the thermal efficiency is lower, and can not adapt to multiple thermal source.

The purpose of this utility model is to provide a kind of can be applicable to multiple thermal source, simple in structure, the multi-functional water heater that the thermal efficiency is high.

The utility model is achieved in that it has a heating spiral coil as water inlet, spiral coil is connected with the circle heating water pond that is welded into by upper and lower cover plate, be equipped with in the outside of spiral coil and heat the conical water jacket that its inside that water pond is connected has water stream channel, between heating water pond and water jacket, leave the gap that combustion gas is passed through, be welded with delivery port on the top of water jacket.During use, connect water pipe earlier, then water heater is placed on the stove fire, when current can heat water during by water heater.

Advantage of the present utility model is, and is simple in structure, easy to use; Water stream channel is long, and water temperature is controlled easily; Because the outside of spiral coil and heating water pond is added with conical water jacket, therefore, efficiency of heating surface height, simultaneously, applicable to multiple thermal source.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is the front view of the utility model upper cover plate;

Fig. 4 is the B-B cutaway view of Fig. 3;

Fig. 5 is the front view of the utility model water proof steel wire;

Fig. 6 is the vertical view of Fig. 5.

As shown in drawings, a spiral coil 1 is arranged in bottom of the present utility model, a circular heating water pond is arranged on spiral coil 1, spiral coil 1 is connected with the heating water pond, said heating water pond is made by upper cover plate 2 and lower cover 3 welding, stamp out groove on the upper cover plate 2, in water pond, form water stream channel, a conical water jacket is installed in the outside of spiral coil 1 and water pond, the heating water pond is connected by tube connector 8 and water jacket, also leaves the gap that a combustion gas is passed through between heating water pond and water jacket; Said water jacket is made up of conical inwall 7 and outer wall 4, also has a spiral water proof steel wire 6 between inwall 7 and outer wall 4, and water proof steel wire 6 welds together with inwall 7, forms a spiral water stream channel in water jacket; Be welded with delivery port 5 on the top of water jacket, an end of spiral coil 1 passes the water jacket bottom as water inlet, and welds together with it, and the other end and 7 welding of water jacket inwall are to fix its position.During use, earlier the water inlet and the running water of water heater are connected, delivery port 5 is connected with shower fitting spray nozzle or other water consumption device, then water heater is placed on stove and accessory or other thermal source, current are heated when flowing through water heater, can be used to have a bath, wash the dishes or wash dish; Water inlet and delivery port and radiator connection as with water heater also can be used for the room heating.

Claims (2)

1, a kind of multi-functional water heater, comprise heating spiral coil (1) and delivery port (5) as water inlet, and the circle that is welded into by upper cover plate (2) and lower cover (3) that is connected with spiral coil (1) heats water pond, it is characterized in that, be equipped with in the outside of spiral coil (1) and heat the conical water jacket that its inside that water pond is connected has water stream channel, between heating water pond and water jacket, leave the gap that combustion gas is passed through.

According to the said multi-functional water heater of claim 1, it is characterized in that 2, said conical water jacket is made up of conical wall (7) and outer wall (5), between inwall (7) and outer wall (5), also be welded with a spiral water proof steel wire (6).
