In the utility model, the electrodeless control is carried out on the angle of the air outlet component through the stepping motor, and the air can come out from multi air ducts; the stepping motor can be controlled through the temperature sensor, and thereby, the air outlet area and the air ducts are controlled.
Description
Technical field
The utility model relates to a kind of air door, particularly relates to a kind of air door by the step motor control gas flow.
Background technique
Have the MOD that is that uses now, use the gear reduction of synchronous machine drives level Four, promoting push rod by end cam pushes open with closing movement and by gear door-plate and is connected with lever, thereby by magnetic patch in the middle of the lever to the rotation of reed pipe control synchronous machine or static, but can only there be the state in two that opens or closes in above-mentioned air door, make that the cool storage area temperature fluctuation is bigger, and when the space is big, there are temperature difference in the top and the bottom in space, and originally the position temperature rate of descent of exhaust outlet is slow.
The model utility content
The utility model purpose provides a kind of stepper motor that passes through and freely controls, reach the air door of one or more air-out, provide a kind of air door for reaching this purpose the utility model by the step motor control gas flow, be connected with stepper motor by coupling shaft, comprise gas by-passing parts and wind component, described gas by-passing parts is made up of baffle plate and at least one air channel, and described wind component divides the air-out zone and the zone of keeping out the wind.
As further improvement of the utility model, the air channel size of described gas by-passing parts is arbitrarily angled between 0 ° to 180 °, can need the discharge quantity of fan size, selects the size in air channel.
As further improvement of the utility model, the air-out of described wind component zone is greater than arbitrarily angled between 0 ° to 180 °, can be according to the design needs voluntarily.
As further improvement of the utility model, described throttle setting is connected with temperature transducer outward, by the temperature sensor signal control that needs cooled region, can control a plurality of different local temperature difference, thereby the control step motor is regulated.
The utility model has the advantages that: the utility model carries out electrodeless control by stepper motor to the angle of wind component, and can reach the air-out together of a plurality of air channels, thereby and can reach control by temperature transducer control step motor to air-out zone and air channel.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 4 is a kind of schematic representation of the present utility model, the utility model provides a kind of and freely controls by stepper motor, reach the air door of one or more air-out, provide a kind of air door for reaching this purpose the utility model by the step motor control gas flow, be connected with stepper motor by coupling shaft 3, comprise gas by-passing parts 1 and wind component 2, described gas by-passing parts 1 is made up of baffle plate 1-1 and air channel 1-2, described wind component air-out in the 2 fens zone 2-1 and the regional 2-2 that keeps out the wind, the air channel 1-2 of described gas by-passing parts 1 is at least one, can connect a plurality of air channel 1-2, and can several air channels 1-2 air-out together, the air channel 1-2 of described gas by-passing parts 1 is greater than arbitrarily angled between 0 ° to 180 °, can need the discharge quantity of fan size, select the size of air channel 1-2, the air-out of described wind component 2 zone 2-1 is greater than arbitrarily angled between 0 ° to 180 °, can be voluntarily according to the design needs, described throttle setting also is connected with temperature transducer outward, by the temperature sensor signal control that needs cooled region, can control a plurality of different local temperature difference, thereby the control step motor is regulated.
The utility model carries out electrodeless control by stepper motor to the angle of wind component, and can reach the air-out together of a plurality of air channels, thereby and can reach control to air-out zone and air channel by temperature transducer control step motor.
The baffle plate 1-1 and the air channel 1-2 that draw together gas by-passing parts 1 as a kind of specific embodiment the utility model of the present utility model adopt 180 °, and the air-out zone 2-1 of the parts 2 that keep out the wind and the regional 2-2 that keeps out the wind also adopt 180 °, and may command, can carry out stepless regulating.
Fig. 1,2 and 3 is the utility model air door, be applied to the most preferred embodiment in refrigerator field, the baffle plate 1-1 of gas by-passing parts 1 is 180 °, it is 90 ° that 2 air channel 1-2 are arranged, the air-out zone 2-1 of parts 2 of keeping out the wind is 90 °, other are the regional 2-2 that keeps out the wind, and be connected with temperature transducer, its two-way air channel 1-2, one the road from the air-out of cold storage room top, another road is controlled stepper motor by temperature transducer by the several holes air-out of refrigerator back, thereby control air channel 1-2 reaches the control to cold storage chamber of refrigerator and bottom refrigeration, this air door can also be voluntarily reaches stepless regulating to the air channel by the control step motor, wherein Fig. 1 is the schematic representation that the utility model only uses an air channel 1-2, and the schematic representation that Fig. 2 uses simultaneously for two air channels of the utility model, Fig. 3 are to close back schematic representation of the present utility model.
