Technical field
The utility model relates to gas kitchen ranges air regulator field, and a kind of energy of saying so more specifically is sectional-regulated and guarantee the adjuster of stable supplying cooker burner primary air.
Technical background
The adjuster of existing burner for household gas range is to be close to burner air-vent plane by air regulating board under the spring pressure effect, is the axle center rotation with the nozzle, covers or open the burner air-vent gradually, realizes the adjusting of primary air amount.Its major defect is that air regulating board can not be located, and changes the area of air-vent easily from line slip, influences the stability that the primary air amount is regulated.Especially more outstanding to the influence of the combustion conditions of natural gas, manufactured gas, manufactured fuel gas's kitchen range, reduced the quality of product.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of energy sectional-regulated and guarantee the air regulator of stable supplying cooker burner primary air.
Further purpose of the present utility model is to provide a kind of effectively locking gas kitchen ranges air regulator.
The utility model is achieved through the following technical solutions its purpose.
The utility model discloses a kind of novel gas kitchen ranges air regulator, adopted the bimetal leaf structure, solved traditional single chip architecture the technical barrier that can't realize, comprise the air regulating board of being located at the air-vent outside on the structure, and between air regulating board and air-vent, be provided with deep bead, the air-vent outside is fixed and be covered in to deep bead, the centre offers air inlet, air regulating board is provided with the avoiding hollow groove that adapts with air inlet, air regulating board cooperates with deep bead is movable, by regulating the relative position of avoiding hollow groove and air inlet, open or closed air inlet.In the process of using, gas nozzle sprays compressed gas in air-vent, and air-flow can drive extraneous air and enter in the air-vent from air inlet and mixes with compressed gas, realizes that primary air is additional.Because deep bead is to be fixed on the air-vent, so the size of air inlet is to adjust according to the relative position of air regulating board and deep bead, structural good, after the relative position of air regulating board and deep bead is fixing, the air inlet size can not change, and the quantitative primary air that provides that thus can be stable replenishes.
For the adjustable of position between air regulating board and the deep bead and realize locking position, the utility model is provided with an adjustable mechanism of adjusting between air regulating board and deep bead, deep bead is provided with the indicating graduation of air regulating board with respect to the deep bead position, the user can adjust the size of required air inlet by indicating graduation, and with respect to the full cut-off and the fully open position place of deep bead limited block is set at air regulating board.Described adjustment detent mechanism optimum structure is to be located at positioning boss on the air regulating board and the gear groove on the deep bead by employing to match and constitute, or adopt the gear groove be located on the air regulating board and the positioning boss on the deep bead formation that matches, this is simple in structure, process simple and easy, easy to use, and location and controllability are good.
The utility model is processed into sector structure with avoiding hollow groove and air inlet, air regulating board cooperates with respect to the deep bead rotary moveable, rotating shaft is the center of circle of above-mentioned fan-shaped place circle, adopt the adjustment mode of rotating to make and regulate more simple and convenient, and gas spray head can be arranged on rotating shaft position, or, further simplify the structure as the rotating shaft use.Do that avoiding hollow groove and air inlet are two fan-shaped openings of symmetry after the further improvement, rotating shaft is positioned in the middle of two openings, avoiding hollow groove and air inlet can be processed into 90 symmetrical degree hatch frames, the fan-shaped opening of aerofoil and deep bead can stagger overlapping fully and fully on the position of complete open and close, the simple and easy and simplified structure that complete symmetrical structure helps processing.
For improving the sealing of structure, the utility model is provided with the air door spring in rotating shaft, and air door spring compacting air regulating board is close to deep bead, can reduce to make the slit that air regulating board cooperates with deep bead, improves sealing.
The utility model can be applicable to single air-vent structure or two air-vent structure, or even many air-vents structure, as long as simple configuration and the same number of air regulator of air-vent.
The utility model has following substantive distinguishing features and progress with respect to prior art:
1. adopted the bimetal leaf structure, solved single chip architecture the technical barrier that can't realize, be a kind of design is ingenious, control easily, new technology with low cost, applied widely, convenient and practical;
2. be provided with the adjustment detent mechanism, adjusting and locking that can simple realization air inlet size have more practicality and security;
3. fan-shaped air inlet structure cooperates the adjustment mode of rotation, further simplifies the structure, and improves operating flexibility;
4. the structure of air door spring can not reduce the sealing that improves structure under the prerequisite that cooperates flexibility.
