Abstract
The utility model relates to the technical field of refrigerators and discloses an air door device for a frost-free refrigerator. The air door device is characterized by comprising an adjustable air door of an air channel opening arranged between a refrigerating chamber and a cold room, an electric motor connected with the air door, and a controller connected with the electric motor. Compared with the prior art, the air door device more reasonably allocates refrigeration capacity and can ensure maximum increase in freezing capacity as far as possible; the frequent open and stop of a compressor can be avoided so that the service life of the compressor is improved; and the operation time of a refrigeration system is less and the air door device achieves noiseless effect.
Description
Technical field
The utility model relates to the refrigerator technical field, it specifically is a kind of throttle setting of controlling the frost-free refrigerator of refrigerating chamber door opening degree, the refrigerating chamber, the temperature of refrigerating chamber that guarantee refrigerator when freezer compressor is worked reach requirement substantially simultaneously, make the refrigerating efficiency of refrigerator keep higher state.
Background technology
The refrigerating chamber and the refrigerating chamber air door of existing frost-free refrigerator only open or close two states, it is little that the greatest problem of this air door is that leeway is regulated in the distribution of cold, can not guarantee freezing, refrigeration synchronously, so refrigerating efficiency is not high, energy consumption of refrigerator is big, the high frequent switching on and shutting down.
The utility model content
The purpose of this utility model is the throttle setting that the shortcoming that overcomes above-mentioned prior art provides a kind of frost-free refrigerator, thermic load, cooling rate according to refrigerating chamber, refrigerating chamber, automatically damper is opened size, the refrigerating chamber of refrigerator, the speed of refrigerating chamber cooling are consistent, its operational efficiency height, cooling is fast, energy consumption is little, be easy to energy-conservationly, also can reduce the start number of times of compressor, food refrigerating and fresh-keeping is effective simultaneously.
Realize the throttle setting of the following a kind of frost-free refrigerator of technical scheme of the utility model purpose, but comprise that the air register of being located at wind passage mouth between refrigerating chamber and the refrigerating chamber, the motor that links to each other with air door reach the controller that links to each other with motor.
Described air door is connected on the refrigerator body by hinge axis, and hinge axis is connected with the output shaft of motor.
Described throttle setting also comprises the stopping means that limits the door opening angle.Described motor is a stepper motor.
Described throttle setting also comprises the temperature detector that one or two link to each other with controller, if one, then be located at refrigerating chamber or refrigerating chamber, if two, then be located at refrigerating chamber and refrigerating chamber respectively.
The utility model compared with prior art possesses following advantage:
(1) the utility model cold distributes rationally, can guarantee to improve to greatest extent refrigerating efficiency as far as possible;
(2) the utility model can avoid high frequent to open, stop, and compressor is guaranteed service life.
(3) refrigeration system still less reaches quiet effect running time.
Description of drawings
Fig. 1 is the structural representation of the throttle setting of the utility model frost-free refrigerator;
Fig. 2 is the schematic cross-section of A-A ' among Fig. 1.
The specific embodiment
As shown in Figures 1 and 2, a kind of throttle setting of frost-free refrigerator, but comprise the air register 3 of being located at wind passage mouth between refrigerating chamber 1 and the refrigerating chamber 2, the motor 4 that links to each other with air door and the controller that links to each other with motor 4.
Described air door is connected on the refrigerator body by hinge axis 6, and hinge axis 6 is connected with the output shaft of motor 4.
Described throttle setting also comprises the stopping means 7 that limits the door opening angle.Described motor is a stepper motor.
Described throttle setting also comprises the temperature detector of being located at refrigerating chamber and/or refrigerating chamber, and temperature detector is connected to controller.Controller sends the opening angle of control signal control air door according to the temperature of detected refrigerating chamber of temperature detector and/or refrigerating chamber.
The operation principle of above-mentioned throttle setting is as follows: the refrigerator energising begins refrigeration, controller is according to the temperature of refrigerating chamber, refrigerating chamber and the unlatching size of dividing other design temperature control air door, system is after operation a period of time, rate temperature change according to refrigerating chamber, refrigerating chamber, automatically the size of damper again, repeat this process at set intervals, make refrigerating chamber, refrigerating chamber keep identical cooling rate.Can keep refrigerating efficiency the highest like this, avoid the situation of single chamber start simultaneously as far as possible, make high frequent open, stop.
The utility model compared with prior art has following advantage:
(1) the utility model cold distributes rationally, can guarantee as far as possible to improve to greatest extent refrigerating efficiency;
(2) the utility model can avoid high frequent to open, stop, and compressor is guaranteed service life.
(3) refrigeration system still less reaches muting function running time.
Claims (6)
