Abstract

The utility model relates to an exhaust-heat water-heater for liquefied gas range which can use the waste heat of the gas in cooking. The cold water is heated by automatic circulation between a spiral heating pipe and a heat preserving water tank, and the hot water can be stored for a long time for using in a family through the actions of the heat preserving water tank and a non-return device. The utility model has novel structure, simple manufacturing technique, and is an energy saving product which can make up the defect of the existing liquefied gas range and is more practical.

Description

Exhaust-heat water-heater for liquefied gas range

The utility model belongs to a kind of and utilizes liquefied gas cooker burner exhaust heat heating cold water, and the household implements that can store for future use voluntarily.

Since liquefied gas stove enters family, people have lost the convenience that the coal kitchen range can long-time warm water, and special blow-on is heated up water, and the costliness because of liquefied gas makes general family be difficult to accept again, and the appearance of this contradiction has become a difficult problem of puzzlement family.

General home furnace, the thermal efficiency only reach about 15%, and the heat that most of fuel produced is diffused in the atmosphere through waste gas and stove and accessory and has gone.How utilizing the heat that diffuses away as far as possible, and it is stored for future use, is to realize energy-conservation common means.

At present, thrown in a kind of liquefied gas furnace water heater on cooking stove on the market already, its basic structure principle is: with a kind of metal ring container with fire door periphery seal, make it to form hearth box, the burner of diameter 120 millimeter is stayed in the upper end, most of flame penetrates heating cooker from burner when cooking a meal, high hot waste gas and part flame baking container inner wall in the hearth box and heating container inner cold water.Thereby realized when cooking a meal, obtaining hot water.

This water heater, though can realize purpose of energy saving, but have many unfavorable places, one owing to adopt the annular enclosed type hearth box to obtain heat, has hindered the furnace air convection current, makes fuel be difficult to fully cause combustion gas waste and air pollution.Its two because burner diameter is less, part edge flame direct baking has reduced the heating surface area of cooker on container inner wall, make the rate of heat exchange of cooker slack-off, has also just prolonged the time of cooking a meal, that is has strengthened the consumption of combustion gas.Its three because heated water will cool off with stove, do not reach the purpose of deposit hot water.

The utility model has just in time remedied the deficiency of above-mentioned heater.Its objective is that providing a kind of to people is not causing under the prerequisite of new consumption time of cooking a meal and combustion gas, utilize the waste heat when cooking a meal to heat cold water, and store for future use, the desirable apparatus that brings convenience to family.

Description of drawings:

1, the utility model liquefied gas stove waste heat water heater structural representation.

2, water outlet connector non-return device structural representation (A place amplification profile among the figure) under in the utility model.

Now be explained as follows the design is novel with reference to the accompanying drawings:

The utility model liquefied gas cooker waste heat water heater is mainly formed with following each parts: (1), attemperater; (2), tank lid; (3), filling pipe end joint; (4), following water outlet connector; (5), hose; (6), helical heating pipe; (7), dewatering outlet joint.

Its operation principle is: the helical heating pipe (6) that metal is made is placed on the liquefied gas cooker water pond, use hose (5) with two ends and last respectively, following water outlet connector (3), (4) connect, add cold water toward the attemperater made from metal or plastics with filled thermal insulation materials interlayer (1) then, cold water backs down down the non-return device in the water outlet connector (4), enter helical heating pipe (6) through hose (5), along with increasing of water level, make and be full of cold water in the heating tube, when water level is higher than filling pipe end, cold water is by hose and filling pipe end joint (3) and attemperater UNICOM, fill it up with until cold water, cover tank lid (2).

When cooking stove is worked, high hot waste gas after the burning, flow through heating tube spiral slit, make the helical heating pipe inner cold water add thermal expansion, bulk density alleviates, under the effect of cold water pressure at the bottom of the attemperater, heated water flows to the high filling pipe end of water level gradually and enters attemperater, carries out heat exchange.Simultaneously, cold water replenishes the water yield in managing by the following mouth of a river.So just realize the automatic circulation of water, reached the purpose of cold water in the heater incubator.

After cooking stove quits work; reduction along with furnace temperature; hot water is cooled in the heating tube; volume-diminished; Unit Weight increases; the pipe inner cold water produces the trend that flows in the downward mouth of a river; under the effect of water flow pressure, the non-return device in the following water outlet connector is closed, and has blocked the circulation of water; making hot water in the attemperater no longer flow into heating tube is cooled; hot water is under the protection of heat-insulation layer in the case like this, and thermal diffusion is slow, thereby has realized the storage of heat energy; having guaranteed has a certain amount of hot water supply in the off time of cooking a meal, not only brought convenience but also realized purpose of energy saving for family.

Because the heating tube of the utility model is shape in the shape of a spiral, have the spiral space of certain width, can not block the circulation of stove inner air and outer air, then can not influence the abundant burning of combustion gas.Simultaneously, behind the shape, length is very big in the shape of a spiral for heating tube, and the tube wall heating surface area is big, and places on the cooking stove water pond, near flame.So can try to achieve the higher thermal efficiency, moreover by the heating tube determining positions, generally speaking, flame can directly not roasted heating tube, just can not reduce the heating surface area of cooker, so the thermal efficiency of cooker just can not be affected yet yet.On the other hand, the utility model has adopted attemperater, has realized the storage of heat energy.These have just constituted the utility model more former water heater novelty, advanced characteristics, make it to have more applicability.

Claims

A kind of have energy-conservation and liquefied gas cooker waste heat water heater heat insulation effect, comprise attemperater (1), tank lid (2), filling pipe end joint (3), following water outlet connector (4), hose (5), spiral heater (6), dewatering outlet joint (7) critical piece, it is characterized in that, heating tube and attemperater are combined into a complete circulatory system, heating tube is manufactured and designed curl, and coiling is placed on the liquefied gas cooker water pond, in following water outlet connector design and installation non-return device.
