Description

Efficient fast water heater

The utility model relates to a kind of water heater, particularly a kind of efficient fast water heater.

General domestic hot water's kettle is to be used for quantitatively boiling water, and can use on various stove and accessorys, but the speed of heating up water is too slow, and the thermal efficiency is low.Wall-hanging water heater can heat circulating water, but can only use a kind of heating energy source (liquefied gas or coal gas or), and can not quantitatively boil water.Chinese patent (ZL932384595) disclosed " efficient energy-saving water heater ", though can heat circulating water, and can use multiple heating energy source, its heat exchange area is less, thereby its firing rate is also just slower.

The purpose of this utility model provides a kind ofly can use various energy resources, can quantitatively boil water, and can heat circulating water again, and thermal efficiency height, heats fast water heater.

The purpose of this utility model is such realization:

Be by water storage outer sleeve (9), heat exchanger coil (27) constitutes, pipe (27) is contained in the interior sky of tube (9), coupled logical, in the centre of heat exchanger coil (27) accumulation of heat outlet pipe (1) is housed also, the sealing of the bottom of this pipe, its middle and upper part are stretched out the upper end of sleeve (9) with after the water side of heat exchanger coil (27) is connected.

The upper surface of water storage outer sleeve (9) have one with the toroidal cavity (28) of its annulus post intracavity inter-connection, there is a bit of flaring burner (22) that advances the lower end, interior bottom is connected with the water inlet of heat exchanger coil (27).

Heat exchanger coil (27) be by in spiral, in, outer three heat exchanges prop up coil pipe (6), (7), (8) and inlet union (12) thereof, (16), (23), outlet connection (3), (19), (26) and corresponding water shutoff packing ring (14), (15), (24), (4), (18), (25) are formed, the coiling diameter of three coil pipes (6), (7), (8) is corresponding little respectively, in, big, and mutually wrong 120 ° of PHASE DISTRIBUTION.

Joint (12), (16), (23), (3), (19), (26) all are nuts, and the left and right sides two halves of its internal thread are respectively left-handed and right-handed thread.

Heat exchanger coil (27) also can prop up coil pipe and corresponding joint and water shutoff packing ring thereof by the 4-8 root to be formed, and the number of plies of its coiling also can be the 4-10 layer.

Efficient fast water heater of the present utility model, owing to add toroidal cavity in the upper end of water storage outer sleeve (9), centre at this cavity also is provided with floss hole, and, heat exchanger coil (27) adopts spiral coil pipe more than three, has increased heat exchange area, thereby, improve the thermal efficiency, speeded firing rate.Simultaneously, the water inlet of coil pipe (27) is provided in a side of its bottom, can be used for heating circulating water at ordinary times and makes shower or cleaning or heating usefulness, when the water intaking valve (10) of sleeve (9) bottom when closing, can quantitatively boil water again.Again because the bottom of sleeve (9) is provided with the burner that advances of segment loud-speaker shape, help the convergence of flame, its bottom surface matches with general stove and accessory, both applicable to coal kitchen range (stove), again applicable to liquefied gas (coal gas) kitchen range and electric furnace, also because top is provided with floss hole, thereby also again applicable to bavin (grass) kitchen range, so this water heater can be used for multiple heating energy source.

Accompanying drawing 1 is a main cutaway view of the present utility model.

Accompanying drawing 2 is the utility model cutaway views along the A-A axis.

Accompanying drawing 3 is the utility model cutaway views along the B-B axis.

Below in conjunction with accompanying drawing, describe an embodiment of the present utility model in detail.

Efficient fast water heater of the present utility model is by outlet pipe (1), water storage outer sleeve (9), and heat exchanger coil (27) constitutes.

Outlet pipe (1) is a diameter than the bigger metal tube of heat exchanger coil, its lower end closed, and the middle and upper part is evenly equipped with three breeches pipes that communicate with its inside branch, and breeches pipe all has left hand thread at tail end, and there is external screw thread the upper end of pipe (1).

Water storage outer sleeve (9) is that toroidal cavity (28) is arranged on one, down the annulus post inner chamber that communicates is with it arranged, and the cross section is Shape, middle toroidal cavity (28) includes a tube plate (21) that protrudes upward above it, and there is screw the upper end of tube plate (21), fixes outlet pipe (1) with bolt (20) and (2), and the endoporus of tube plate (21) is also as floss hole; The both sides of sleeve (9) upper end also are equipped with handle (17) and (5), the inboard, lower end has the burner (22) that advances of a bit of flare to be used to assemble flame, the inboard place of slightly going up, lower end is evenly equipped with three breeches pipes, the end external screw thread of this breeches pipe is a left hand thread, be used for being connected with heat exchanger coil (27), the right, the outside, lower end also has a water inlet breeches pipe (11) and dress water intaking valve (10) thereon.

Heat exchanger coil (27) is by interior, in, (size by the coiling diameter is decided to be little in other words outward, in, prop up coil pipe (6) greatly), (7), (8) and the water supply connector of lower end (12), (16), (23) Shang Duan water out adapter (3), (19), (26) and corresponding water shutoff packing ring (14), (15), (24), (4), (18), (25) form, the coiling number of plies of propping up coil pipe is more than 3 layers, it advances, the external screw thread of delivery port all is a right-handed thread, be used for joining with the breeches pipe of outlet pipe (1) middle and upper part and the following inboard breeches pipe of outer sleeve (9), the water shutoff packing ring is to make with the flexible material of ability temperature more than 100 ℃, joint (12), (16), (23), (3), (19), (26) all be nut, its internal thread is divided into left and right sides two halves from the centre, half is a left hand thread, and another is a right-handed thread.

During installation, earlier coil pipe (6) is propped up in heat exchange, (7), (8) water side (i.e. upper end) joins with the middle and upper part breeches pipe of outlet pipe (1), screw joint (3), (19), (26), at this moment, because the upper end screw thread of coil pipe is dextrorotation, pipe (1) breeches pipe screw thread is left-handed, so can connect tight soon, thereafter, the endoporus of the tube plate (21) above the space upwards passes in the bottom of outer sleeve (9) with the upper end of outlet pipe (1), with joint (12), (16), (23) breeches pipe with the lower inside of itself and sleeve (9) joins, and outlet pipe (1) is fixed on the middle cavity of sleeve (9) with bolt (20) and (2).

During use, earlier the bottom with water heater places on the kitchen range (13), the water inlet pipe (11) of feed pipe and sleeve (9) is joined, and the upper end of water pipe and outlet pipe (1) is joined.Open the control fire device of valve (10) and kitchen range (13), cold water will enter the interior annulus post cavity of sleeve (9) from pipe (11), then enter heat exchange from the breeches pipe of inboard, its underpart and prop up coil pipe (6), (7), (8), and enter outlet pipe (1) from the water side and provide mobile hot water to water pipe, both can be used for shower, can be used to again clean, also can be used for heating.During filled with water, turn off valve (10) in pipe, heating can quantitatively boil water, and emits boiling water from managing (11).Its heat transfer process is: the flame of kitchen range (13) is directly passed to three coil pipes on the one hand; Pass to outlet pipe (1) on the other hand, pass to the inboard cylinder of sleeve (9) more on the one hand, feed-water preheating; Also have on the one hand, pass to the toroidal cavity (28) of sleeve (9) upper end, so that make full use of waste heat, like this, the inboard cylinder preheating of cold water by sleeve (9) and the UTILIZATION OF VESIDUAL HEAT IN above it, again through heat exchange prop up coil pipe be heated to outlet pipe (1) go up the middle part time, add the hot water that rises in outlet pipe (1) bottom again, thereby the further raising of having got back of its temperature is so its heating of the water heater of present embodiment is fast, the thermal efficiency is high.
