Abstract

An internal combustion smoke discharge gas stove that is safe, energy saving and environment protection includes a burner, a switch, a burning case and a fire opening arranged on the burning case, which is characterized in that the burner arranged in a furnace chamber is provided with a lifting regulation bracket; the inner walls of the burning case is provided with circular smoke discharge channels; the exit of the circular smoke discharge channel connects to a smoke discharge pipe to release the burning wastes; a rotary transmission means of the regulation bracket on the burner consists of a screw shaft, two nuts and a rotary hand wheel; the two ends of the screw shaft is provided with threads whose thread pitch is identical and rotary direction is reversed; the two nuts are arranged symmetrically on both ends of the screw shafts, which connect to the burner by means of a four-bar linkage; the gas stove is provided with a smoke discharge hood above the fire opening; the smoke discharge port on the smoke discharge hood connects to the smoke discharge channel which releases the oil smoke to the outside by means of natural winds during cooking, which settles problems related to indoor pollution by oil smoke, thereby saving energy.

Description

Internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker

Affiliated technical field: the utility model belongs to household gas range, and what be specifically related to is internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker

Background technology: the gas-cooker that sell on the market now, people generally uses, all be that burner is fixed on the hearth plate face, the naked light burning, three fulcrums head on the pan of heating up water and cooking, the dirty waste gas of cigarette directly is emitted on indoor, contaminated environment, harm people's health, as leak combustion gas, can cause smoked people, explosion accident.

Existing household gas range all will consume indoor oxygen when burning, and discharge toxic gas and particles such as carbon monoxide, carbon dioxide, sulfur dioxide, oxynitrides, aldehydes, BaP and the fine grit of cigarette ash, can certain excitant be arranged and have potential carcinogenicity eye conjunctiva, respiratory mucosa, nervous system.

Existing solution is that a cover smoke exhaust is installed above gas-cooker, opens the smoke exhaust discharge of noxious gases when gas-cooker is lighted, but also has the noise pollution problem of smoke exhaust.

The purpose of this utility model has designed a kind of internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker for addressing the above problem exactly.

Summary of the invention: internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker, include burner and switch thereof, combustion box and the burner that is located on the combustion box are formed, be burner hearth in the said combustion box, combustion box is provided with the flame observation port, burner on the combustion box can be provided with a plurality of pyrospheres according to the size of burned utensil, the middle pit of the stomach of pyrosphere is provided with the burner lid, it is characterized in that the burner that burner hearth is installed is provided with liftable adjusting bracing frame, the combustion box inwall is provided with the annular row flue, said annular row flue is the cannelure of upper shed, the external smoke exhaust pipe of annular row flue outlet, the refuse of burner after combustion box burner hearth internal combustion is discharged to outdoor through the external smoke exhaust pipe of the outlet of the cannelure of upper shed.

The said liftable adjusting support of installing in the burner hearth of burner that is located at, form by screw-drive mechanism, guider and four connecting rod elevating mechanisms, kitchen range frame in left and right sides guide post and the combustion box burner hearth is fixedly mounted on the burner hearth below, on the horizontal plane parallel with the burner on the combustion box, the central vertical of plane burner on burner and the combustion box.

The screw-drive mechanism that said burner is regulated support is made up of a screw rod, two nuts and rotation hand wheel, the two ends of screw rod have screw thread, its pitch equates that rotation direction is opposite, and two nuts cooperate symmetrically and are installed in the screw rod two ends, and said two nuts are connected by four connecting rods with burner.

The top of said combustion box is provided with fume exhaust cover, and the smoke evacuation interface on the fume exhaust cover is connected with smoke discharging pipe, and utilizes the negative pressure of smoke discharging pipe to be discharged to outdoor naturally.

Description of drawings: accompanying drawing 1 is the main structure schematic diagram of internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker of the present utility model;

Accompanying drawing 2 is structural representations of burner lowering or hoisting gear;

Accompanying drawing 3 shows the structural representation of cooking stove panel and fume exhaust cover;

Accompanying drawing 4 is body structure figure of internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker of the present utility model; Wherein: the 1-plane kitchen range top, the pyrosphere of 2-burner, 3-burner lid, the 4-burner hearth, 5-waste discharge smoke inlet, 6-annular row flue, the external smoke exhaust pipe of 7-, 8-burner, 9-bracing frame, the 10-screw rod, 11-nut, 12-handwheel, the 13-fume exhaust cover, 14-oil extraction mouth, 15-kitchen range top cover plate, 16-fume exhaust cover interface, the 17-chamber door.

The specific embodiment: the kitchen range top of the present utility model and casing adopt the sheet metal manufacturing, and the operational process of its smoke evacuation system is: combustion-supporting air enters burner hearth from burner hearth bottom, at burner hearth formation smooth air from low to high.Be installed in the burner of burner hearth central authorities, the straight perpendicular flame that ejects becomes umbrella shape under the effect of the bottom of a pan cone, burn equably around the pot wall cmpletely, and waste gas after burning enters in the annular row flue, discharges outdoor through smoke evacuation system.

Heating up water when cooking, the pyrosphere that a plurality of different sizes that burner adapts according to the dimensional configurations of pan constitute makes the pan that is sitting in burner close stockhole, and it is indoor to prevent that flue gas from entering, and pan also has good stable.The distance of burner and pan is regulated the height of burner by rotating handwheel 12, makes burner reach the best combustion effect; During the stove and accessory of stopping using, airtight because of the pyrosphere that is provided with a plurality of different sizes on burner can effectively prevent to arrive indoorly with gas leakage in the burner hearth, effectively protected indoor environment, has the remarkable environmental effect.

Said fume exhaust cover 13 is provided with movable rotation-shaft, smokejack inserts smoke evacuation system by pipeline through fume exhaust cover interface 16, when preparing a meal, kitchen range top cover plate 15 is started, expose burner, it is relative with the kitchen range mouth that oil extraction mouth 14 is adjusted to, and opens chamber door and can regulate burner height by adjusting handle, by peephole observation burner combustion situation.When not preparing a meal, fume exhaust cover can be revolved turn 90 degrees and stand on the wall of kitchen.

When cooking when heating up water, when particularly cooking, for the oil smoke that prevents to cook is arranged to indoor, pollute indoor environment, above the burner of internal combustion smoke evacuation formula safety energy-conserving environment protection gas-cooker, enclosure 13 is set, the smoke evacuation interface of fume exhaust cover is connected with pipeline 7, and the oil smoke row who produces when utilizing the gravity-flow ventilation principle to prepare a meal has solved the problem of fume pollution indoor environment when preparing a meal to outdoor.Because of it is gravity-flow ventilation, have the effect of energy savings, effectively solved the noise pollution problem that the electric-controlled mechanical smoke exhaust produces.
