Description

Coal burning water-heater for shower

The utility model relates to a kind of water heater, more particularly, is a kind of coal-fired shower heater.

The existing market shower heater is various in style, has electrically heatedly, coal gas heating is arranged, and coal-fired heating is also arranged.Preceding two class water heaters are complex structure not only, and cost an arm and a leg, and use the restriction will be subjected to electricity, gas, for example, power shortage or do not have the area of coal gas just to be not suitable for water heater with this class.Current many in addition areas life mainly is to cook, warm oneself with coal, also uses the coal heating water heater simultaneously.Disclose a kind of technology of stove fire heating water heater in CN2017327, this is a kind of water heater of secondary heat exchange mode, and it is the water that utilizes in the stove fire heating thermal-arrest evaporating pan, makes it boiling and produces low pressure water vapor, with the water in this Steam Heating tank.The water-heater heat-exchanging efficient of this structure is low, the waste coal.Disclose the water heater that a kind of tank is grouped into by plurality of partitions etc. in CN2031068, water pushes, replaces, intersects heat absorption gradually during heating in container, can cause the increase of current dynamic resistance like this, even influence the heat exchange of water.Disclose a kind of each end that is made of several U-shaped heating tubes and communicate with cold and hot water cavity respectively in CN2040229, cold and hot water cavity overlaps each other, and the U-shaped pipe is pressed the distributing position of honeycomb briquette coal eye and arranged.This structure is for the smaller coal stove of coal stove fire box internal diameter, and bend pipe is difficulty very, and is difficult for installing, thereby its utilization is very restricted.

The purpose of this utility model provide a kind of simple in structure, heat exchange good, cheap coal-fired shower heater.

The utility model is achieved like this, it comprises heater, storage tank and upper and lower circulating water pipe.Heater is hood-like parts, and hydroecium is communicated with heat-transfer pipe, in the bottom and the air inlet pipe junction of hydroecium one gas outlet is arranged.Air inlet pipe is one section pipe, during use, place between flue and the coal, the flue gas in the stove is discharged from the gas outlet through air inlet pipe, heat-transfer pipe, again through the outer wall of hydroecium around a week, final flue from stove is discharged to outdoor, because the heating of flue gas is heated the water in heat-transfer pipe and the hydroecium, water in heated water and the storage tank is by upper and lower circulating water pipe circulation, and the water temperature in the storage tank is risen, when water temperature reaches temperature required, get and can in stove, take out heater.The storage tank of this water heater can be fixed on certain place, and as hanging on the wall, it highly quite or be higher than human body height.The heater of water heater simple in structure, volume is little, can be as required, place at any time or take out in the stove.Generally can when stove is banked up a fire, replace cap seal to bank a fire, utilize the waste heat heating of stove with heater.Can save greatly like this and use coal.Water in 80 liters of storage tanks of general heating only need promptly can be used to shower in 3 hours.If want accelerated warming, as long as oven door opening, the very fast rising of water temperature.

Water heater of the present utility model is simple in structure, volume is little, handling ease, easy to use, save the energy.

Fig. 1 is an installation diagram of the present utility model;

Fig. 2 is the front view of the utility model heater;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the vertical view of the utility model heater.

As seen from Figure 1, water heater of the present utility model comprises cocycle water pipe 3, the lower circulating water pipe 4 of heater 1, storage tank 2 and connection heater 1 and storage tank 2. Heater 1 comprises that hydroecium 5, heat-transfer pipe 6, air inlet pipe 7, gas outlet 8, water inlet adapter 9, water outlet adapter 10 and seal retainer ring 11(see Fig. 2,3,4). Hydroecium 5 is a spill cavity volume on the top of heater 1, and heat-transfer pipe 6 is to be positioned at the recess space straight tube, and the two ends of pipe communicate with the internal ring wall of hydroecium 5 bottoms. The lower end edge annulated column inwall of hydroecium 5 connects an air inlet pipe 7, and diameter and the flue of air inlet pipe 7 are complementary. Have fan-shaped gas outlet 8 in hydroecium 5 bottoms. In hydroecium 5 external wall of upper portion one seal retainer ring 11 is arranged, it is to be the axial location of fixed heater 1 in stove, and can reduce the leakage of the flue gas in the stove. Have in the upper surface of hydroecium 5 and to take over 4 into water and join with the lower circulating water pipe 4 of storage tank 2, there is the cocycle water pipe 3 of water outlet adapter 10 and storage tank 2 to join, thereby link up the hydroecium 5 of storage tank 2 and heater 1, hydroecium 5 can be circular-shaped, concave cavity and also can be square, polygon cavity.

Using method of the present utility model is as follows: when needs heating shower water, filling with water in the storage tank 1 that is suspended on certain altitude, also injected water by lower circulating water pipe 4 in the hydroecium 5 of heater 2 simultaneously earlier. Again heater 2 is placed in the stove, the air inlet pipe 7 of heater 2 is entered in the flue. But be noted that the gas outlet 8 in the heater will be in rightabout with the floss hole of stove. The seal retainer ring 11 of heater 2 just is fixed on heater 2 in the furnace chamber. At this moment, the flue gas in the stove is just through the groove of air inlet pipe 7, heat-transfer pipe 6, hydroecium 5, and 8 exports from the gas outlet, pile warp hydroecium one week of 5 external wall of upper portion, discharges from floss hole at last again. Because flue gas is to heat-transfer pipe 8, hydroecium 5 Heating, the water in the hydroecium 5 is heated, thus with storage tank 2 in water circulation so that the water in the storage tank 2 has also obtained intensification, when water temperature reaches the shower requirement, can have a bath, simultaneously heater 2 is taken out in stove.

Go out in order to make unlikely 8 short circuits from the gas outlet of flue gas, can be in the gas outlet 8 add a baffle plate 12. For the ease of observing water level and water temperature, can water-level gauge and thermometer be installed at storage tank 2.

Embodiment.

The shower heater of present embodiment is mainly heated with magnificent Feng Jieneng stove.

The storage tank of water heater is that a volume is 80 liters a container, and there is water inlet on its top, and the cocycle water swivel is arranged at the top of side, joins with the cocycle water pipe, and water tank bottom has following recirculated water joint, with the following circulating water pipe (see figure 1) of joining.

Its hydroecium total height of the heater of water heater is 85, and diameter is 145, and the column part height on hydroecium top is 20, the internal diameter of hydroecium annulus post is 135, the air inlet pipe diameter is 135, highly is 115, and water-in and water-out pipe joint height is when being 100, the gas outlet height is 65, radian is 40 °, and the deep bead height is 20, and the heat-transfer pipe diameter is 14, present embodiment adopts three heat-transfer pipes, is distributed in the groove.

In sum as seen, the utility model is simple in structure, handling ease, and economize coal, using method is easy, and is with low cost.For the user who cooks with coal stove, this is a kind of economical and practical hot water for shower bath device.
