Abstract

The utility model relates to a self-jetting type high-effect energy-saving steam-and-water two-purpose stove. A lower water jacket 3 of the utility model is communicated with a water jacket 5 of a stove plate by a rising pipe 4; the lower part of the lower water jacket 3 is provided with a fire grate 2; one end of a preheater 9 is communicated with the lower water jacket 3, and the other end is communicated with a return water pipe 14; a vaporizing devices 7 comprises a vaporizing jacket 71 which is arranged in a stove chamber and a jetting disc 72 which is arranged at the lower part of the fire grate 2. The steam which is vaporized by the vaporizing jacket 71 jets from the jetting disc 72 to accelerate the combustion of fuels in the stove chamber. So the temperature rises up quickly and the steam in the vaporizing jacket 71 can be used after leading out. After used, the hot water which is led out from the water jacket 5 is recovered from the return water pipe to circulate once more. The utility model which is suitable for using in a family, a restaurant and a field construction unit has the advantages of quick speed of heating up, energy saving and two purposes of steam and water.

Description

The energy-efficient steam-water dual-purpose stove of Self-spraying

The utility model relates to the energy-efficient steam-water dual-purpose stove of a kind of Energy-saving stove, particularly Self-spraying.

Traditional coal stove purposes is single, be used for warming oneself and cooking, with after improve, in burner hearth, increase water jacket, both can be used to heating and cooked, the hot water in the available again hearth water sleeve is as the recirculated water in the hot-water heating gas, and this stove is when lighting or when being the very hot oven state from the anneal state is curved, need air blast to come blowing-in and combustion-supporting, the shortcoming of this stove is:

Air blast needs electric power to drive and wants consumed power, and the air blast cost is higher, causes this stove cost to increase; When having a power failure, blow, then heat up both slow and do not reach required high temperature without air blast; The water jacket heating surface area is less, can not fully absorb heat; What air blast sucked is cold air, and the backwater that circulation is sent into also is cold, and during the circulation heating, consumption of calorie is more: therefore this stove cost is higher, and consumption fuel, electric power are bigger, and the heating-up time is longer.

The utility model purpose be propose a kind of without air blast and easy to operate, can fuel savings, the energy-efficient steam-water dual-purpose stove of Self-spraying of quick heating temperature height, hot water supply function and steam.

The utility model is achieved in that it includes lower water jacket 3, tedge 4, stone or metal plate for standing a stove on as a precaution against fire water jacket 5, vapourizing unit 7 and preheater 9; Lower water jacket 3 leads to through tedge 4 and stone or metal plate for standing a stove on as a precaution against fire water jacket 5, and fire grate 2 is equipped with in the below of lower water jacket 3; Preheater 9 is arranged in flue 20, and one end and lower water jacket 3 lead to, and the other end and return pipe 14 lead to; Vapourizing unit 7 injection water steam are to quicken the burning of fuel in stove, it is rapidly heated, it includes vaporization cover 71 that is arranged in burner hearth 16 and the injection dish 72 that is positioned at fire grate 2 belows, and an end and the water inlet pipe 10 of this vaporization cover 71 lead to, and the other end and injection dish 72 lead to; Vaporization cover 71 is hollow annular cover, makes with the copper material that conductivity of heat is strong, is difficult for reducing the life-span because of heated oxide; Injection dish 72 is made up of the some ring pipes 74 and the person in charge 73 that leads to it, be responsible for 73 and ring pipe 74 on have spray-hole 75; The U-shaped pipe 1 that is communicated with it is housed on lower water jacket 3 inwalls, had both increased heating surface area, also can avoid the lower water jacket 3 uneven air-resistance phenomenon that produces that is heated.During work, cold water from return pipe 14 through preheater 9 preheatings, again through lower water jacket, tedge 4, after 5 heating of stone or metal plate for standing a stove on as a precaution against fire water jacket, hot water flows out to the place to use from the outlet pipe 6 that is positioned at stone or metal plate for standing a stove on as a precaution against fire water jacket 5 tops, flow into preheater 9 through return pipe 14 again after the cooling, so automatically circulation; The effect of vapourizing unit 7 is the combustion-supporting and supply steam of spray vapour, when using the vapourizing unit uperize, steam valve 15 is opened, steam upwards sprays through the below of injection dish 72 from fire grate 2 from vaporization cover 71, combustion-supporting through spray vapour, burning is vigorous rapidly with stove fire, also can draw steam and use.

In sum, the utility model is rapidly heated it, the efficient height owing to adopt vapourizing unit; The place all adopts water jacket at a plurality of heating surfaces, has increased the water jacket heating surface area, has accelerated the rising of water temperature and has prolonged the water temperature retention time, and adopted preheater, has all saved fuel; Owing to remove the air blast that disappeared, both reduced the cost of stove, saved electric power again, particularly more suitable in the not enough area of the supply of electric power that often has a power failure; Open main fire door 23 during use, can heat up soon and cook or heat up water, the hot water of usefulness such as water jacket can be supplied with heating, has a bath, laundry, vapourizing unit also can be supplied steam, to be used for steaming food or sterilization, reaches the effect of steam, hot water two purpose; Since be the stress-free automatic circulation that hot water rising cold water descends, safe in utilization; The small part of gas is met cold air and is reduced into water in the stove, covers on the ashes surface, makes that ashes are unlikely to fly upward, and also the ashes drawer can be housed at furnace bottom, keeps hygienically clean.
