Description

Diameter-changing smoke-stop accessory for pot holding mouth of stove

The present invention relates to a kind of can envelope collection flue gas by the seat pot kitchener of the chimney discharging structure of signing an undertaking; It can be used as the structure of gas furnace, also can be used as combustion of liquid, solid-fuelled Range structure.

Existing general kitchener can divide two big classes: a class is the unscreened primitive form of naked light house gas boiler as existing; This class stove has a lot of shortcomings, just like: (1) is dangerous: naked light exposes, and easily catches fire; Gas furnace is then easily dangerous because of the wind accident extinguishing.(2) heat is imitated low: stove fire, hot gas easily fly away because of the wind heat, and thermal efficiency reduces.(3) pollute big: external direct heat radiation of stove fire and flue gas are in the kitchen, and indoor flying away becomes kitchen, household greatest contamination source, the environment of making dirty, dirty erosion implements, impair one's health and spirit etc.

The second class stove that occurs for the critical defect of avoiding naked light not have the type of barrier stove is that stove fire blocks on every side, can seal the screening fire collection cigarette stove (kitchen range) that the collection flue gas is discharged by chimney; But the seat pot of existing this class stove and accessory mouthful is to make fixing and only can adapted a kind of pot entirely, need not be this just can not seal the collection flue gas during pot, and the shortcoming of answer first kind stove, thus can only a stove to one pot of special use, limited the use of this class stove greatly.

The purpose of this invention is to provide the new class seat pot mouth diameter Range structure of modulation as required.It can hide fire collection cigarette and overcome the shortcoming of first kind stove, and seat pot mouthful diameter adjustable avoid the second class stove can only a stove to one pot use limitation; Promptly the usefulness that all has envelope collection flue gas to be discharged by chimney when the pot diameter of sitting adapted is in scope of design has improved applicability, and has been convenient to be extensive use of.

Implementing method of the present invention is in the interlayer that adds of the boiler face at second stove and accessory, stretches out multi-disc activity leaf lobe to seat pot mouth; The leaf lobe repeatedly encloses around seat pot mouth arranges, and encloses in the present pot mouth and cuts shape or the seat pot hole near garden shape; Crooked linear leaf lobe number was many more in inner edge became, and seat pot Kong Yue is near desirable garden shape; The synchronous swing of leaf lobe then makes the seat pot bore dia can stepless modulation, but the center, hole is constant, and to the center swing, the aperture dwindles the leaf lobe together, otherwise enlarges.

For the minimum-value aperture that reaches less than the stepless modulation of leaf lobe of the diameter of seat pot or usual only with one or two kind of specification pot the time for easy, the pot of pot hole and minor diameter of can also being present is joined the envelope cigarette metal plate (ring) of putting suitable internal diameter and external diameter between the body, the level change is done in seat pot hole dwindled, reach envelope cigarette effect.Envelope cigarette metal plate (ring) periphery repeatedly is put on the boiler face of leaf lobe face or seat pot mouthful periphery, and the seat pot hole hoop that diameter is decided at the middle part pastes the pot body.

Because the seat pot hole size of stove and accessory of the present invention is variable, the pot that uses the different-diameter specification all there is envelope collection flue gas effect, avoided general fire collection cigarette stove one stove that hides to one pot the limitation that makes, be convenient to be extensive use of the critical defect of avoiding naked light not have blocking stove; Be not afraid of wind, reach safe, energy-conservation, reduce pollution, improve the natural environment in kitchen and room, and can reduce or remit the artificial Air conditioner air exchange power consumption and the equipment investment in kitchen, room.

Accompanying drawing is a kind of single head gas furnace embodiment with structure function of the present invention.

The heat insulation surface layer (13) and the supporting plate (4) that have garden shape seat pot mouth (16) at the middle part form the boiler face interlayer.The diameter of seat pot mouthful (16) is decided by the maximum demand diameter in the seat pot hole (14) of the stove setting of originally cooking a meal.Arranging in one-tenth garden week on supporting plate (4) face in the boiler face interlayer around the seat pot mouthful leaf lobe (12) of curved crescent, it can be around rachis (8) rotation that is inserted on the supporting plate (4).

The synchronous swing of the leaf lobe here is to stir the interlock ring (9) that handle (6) promotes garden shape that pulls out that stretches out the stokehold face by the people, order becomes the equal angular device to stir device simultaneously pull out ear (10) on every leaf lobe at the leaf bar (11) that pulls out on the interlock ring (9) with every leaf lobe, reach the synchronous swing of each leaf lobe.The interlock ring is positioned on the supporting spring (7) that is arranged in supporting plate (4) garden week, makes the interlock ring only be subject to and can make garden Zhou Yizhuan.

Envelope cigarette metal plate (19) here circlewise, its outer rim lip (17) is that card is put on the seat pot hole that boiler face seat pot mouth or leaf lobe surround, and promptly the internal diameter of outer rim lip can be the interior arbitrary value of seat pot bore dia excursion that the leaf lobe surrounds.Be evenly equipped with a lot of axially small gaps on the inner edge lip (18) of envelope cigarette metal plate (ring) (19), make the inner edge lip that certain radial elastic is arranged, and pot external diameter of seat that permission is joined have the excursion of Xiao Xu.The nominal inside diameter in seat pot hole changes with the progressive variation of the specification external diameter of various pots in the envelope cigarette metal plate, and establishing a kind of envelope cigarette metal plate (ring) with respect to pot of a kind of specification provides and select for use.

Base plate (3) is arranged under the supporting plate among the figure (4) vis-a-vis, and the two accompanies the perpendicular hot baffle of putting (2) and makes the burner hearth side plate, and the burner hearth that the three surrounds has flue to lead to chimney (20); It below the burner hearth central authorities gas burner (1).Supporting plate (4) is gone up device around the burner has stove ear (15) to make to support the pot of cooking a meal; Drive in the stokehold side as the sight fire window (5) of observing stove fire, the heat resistant glass sealing is arranged on the hot baffle that it faces toward.

Elder generation's taper shank (6) when using leaf lobe envelope cigarette makes seat pot hole that leaf lobe (12) surrounds greater than will sitting pot with the external diameter of pot; Return taper shank (6) then, make leaf lobe hoop paste pot wall, the cooking of can lighting a fire.When using frying pan, pot-placing hole is generally all opened nearly maximum gauge state.When using envelope cigarette metal plate, the suitable envelope cigarette metal plate seat of apolegamy is put and fastened in the seat pot hole of boiler face (or leaf lobe), can sit pot igniting cooking.
