Abstract
The invention belongs to refrigerator accessories, and particularly relates to an air door temperature controller which comprises a shell. an air inlet is formed in the upper portion of the shell, an air outlet is formed in the left side of the shell, a corrugated pipe is arranged in the right side wall of the lower portion of the shell, one end of the corrugated pipe is connected with a temperature sensing cylinder and a tail pipe connected with a capillary, and a driving arm is arranged at the other end of the corrugated pipe. The upper end of the driving arm is connected with an air door corresponding to the air outlet of the shell. A sealing liner is arranged between the air door and the air outlet, a reset piece is arranged between the air door and the driving arm, an adjustment cam is fixed to the left side of the lower portion of the shell, an adjustment plate is arranged on the adjustment cam, an adjusting screw is arranged on the adjustment plate, an adjusting nut is screwed to the lower portion of the adjusting screw, a tension spring is connected to the bottom of the driving arm, and the upper end of the tension spring is fixedly connected to the adjusting nut. The air door temperature controller is characterized in that the temperature sensing cylinder is filled with activated carbon. A containing cavity increases the air storage quantity in the tail pipe, the expansion and retraction quantity of the temperature sensing cylinder is guaranteed, and the opening degree of the air door is guaranteed.
Description
Technical field
The invention belongs to refrigerator annex, particularly a kind of temp controller for air door.
Background technology
Conventional refrigerator is generally divided into refrigerating chamber and refrigerating chamber two parts, be connected by air channel between refrigerating chamber with refrigerating chamber, by fan, cold airflow in refrigerating chamber is blowed to refrigerating chamber, the switch of fan is controlled by a temperature sensing circuit, this structure not only needs additional power to drive fan turns, and can noise be formed during fan turns, temperature in refrigerating chamber is also unadjustable, therefore how to provide a kind of energy-conservation, the temperature control equipment that denoising and refrigerated storage temperature can regulate, become the difficult problem together of pendulum in face of people, existing air damper controller solves the problems referred to above, existing air damper controller controls the opening and closing of air door mainly through expanding with heat and contract with cold of temperature sensing tube, but because in tail pipe, memory space is certain, the tolerance stored is certain, the stroke of temperature sensing tube is less, the problem of throttle opening deficiency may be caused.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, the present invention, by adding active carbon in temperature sensing tube, improves the gas-storing capacity in temperature sensing tube, when the amount of temperature sensing tube by Thermal release gas increases, thus ensure that the stability of bellows stroke, also namely ensure that the stability of throttle opening.
The present invention is achieved through the following technical solutions:
Temp controller for air door, include shell, air inlet is provided with above shell, left side sets out air port, bellows is provided with in shell lower right wall, bellows one end is connected with temperature sensing tube and tail pipe by capillary, the other end establishes master arm, master arm upper end is connected with the air door corresponding with air outlet of casing, sealing lining is provided with between air door and air outlet, reseting plate is provided with between air door and master arm, shell lower left is fixed with adjustment cam, adjustment plate is provided with above adjustment cam, adjustment plate is provided with adjustment screw, adjusting nut is bolted with below adjustment screw, extension spring is connected with bottom master arm, extension spring upper end is fixed on adjusting nut, it is characterized in that: in described temperature sensing tube, be filled with active carbon.
In sum, the present invention has effect:
The present invention is filled with active carbon in temperature sensing tube, active carbon can adsorb the gas medium of temperature sensing tube, when the temperature of temperature sensing tube raises, the gas of absorption discharges from active carbon, promotes bellows and stretches, ensure the stroke of bellows, thus ensure the aperture of air door, after temperature reduces, activity adsorbed gas, thus the closedown realizing air door.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.Wherein:
Fig. 1 is structural representation of the present invention;
In figure, 1 is air door, and 2 is sealing lining, and 3 is reseting plate, and 4 is adjustment plate, and 5 is adjustment cam, and 8 is extension spring, and 9 is master arm, and 10 is adjustment screw, and 11 is adjusting nut, and 12 is bellows, and 14 is tail pipe, and 15 is temperature sensing tube, and 17 is shell.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
Temp controller for air door as shown in Figure 1, include shell 17, air inlet is provided with above shell 17, left side sets out air port, bellows 12 is provided with in shell 17 lower right wall, bellows 12 one end is connected with temperature sensing tube 15 and tail pipe by capillary, the other end establishes master arm 9, master arm 9 upper end is connected with the air door 1 corresponding with air outlet of casing, be provided with between air door 1 and air outlet and seal lining 2, reseting plate 3 is provided with between air door 1 and master arm 9, shell 17 lower left is fixed with adjustment cam 5, adjustment plate 4 is provided with above adjustment cam 5, adjustment plate 4 is provided with adjustment screw 10, adjusting nut 11 is bolted with below adjustment screw 10, extension spring 8 is connected with bottom master arm 9, extension spring 8 upper end is fixed on adjusting nut 11, it is characterized in that: in described temperature sensing tube 15, be filled with active carbon.
In sum, the present invention has effect: 2
The present invention is filled with active carbon in temperature sensing tube, active carbon can adsorb the gas medium of temperature sensing tube, when the temperature of temperature sensing tube raises, the gas of absorption discharges from active carbon, promotes bellows and stretches, ensure the stroke of bellows, thus ensure the aperture of air door, after temperature reduces, activity adsorbed gas, thus the closedown realizing air door.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
