Description

Refrigerator

What the present invention relates to is refrigerator, and what relate in particular to is the cold air control device that can accurately control the refrigerator of the cold air amount that is fed in the refrigerating chamber.

Usually, refrigerator comprises a refrigerating chamber and a refrigerating chamber, utilizes kind of refrigeration cycle respectively these two chambers to be cooled to below the cryogenic temperature and the temperature more than the cryogenic temperature.The Food ﹠ Drink that are stored in the refrigerator are remained on freezing state and frozen state, just can make them be in fresh state for a long time.

The general cold air control device that is provided with in refrigerator is controlled temperature in refrigerating chamber and the refrigerating chamber.In the ideal case, the cold air control device can be controlled at the temperature in the refrigerating chamber in the perishing scope, and the temperature in the refrigerating chamber can be controlled in the scope near temperature of refrigerating chamber, like this, under latter event, when filling food in the refrigerating chamber, just can make refrigerating chamber be used as the storage area of chilled food.

With reference now to Fig. 1,, shown in Figure 1 is the sectional view of conventional refrigerator.

As shown in the figure, conventional refrigerator comprise a definite refrigerator profile body 10, be arranged on refrigerating chamber in the body 10 and refrigerating chamber 20 and 30, one and be arranged on evaporimeter 41 and fan 42 that is arranged in the body 10 that is used to produce cold air between refrigerating chamber 20 and the refrigerating chamber 30, this fan is used for the cold air that evaporimeter 41 produces is forced to deliver to refrigerating chamber and refrigerating chamber 20 and 30.

Be used for guiding cool air that evaporimeter 41 is produced pipeline 22 and 32, be separately positioned on the rear portion of refrigerating chamber and refrigerating chamber 20 and 30 to refrigerating chamber and refrigerating chamber 20 and 30.In addition, on the rear wall 21 and 31 of refrigerating chamber and refrigerating chamber 20 and 30, have a plurality of air admission hole 21a and 31a, cold air enters in refrigerating chamber and the refrigerating chamber by these air admission holes.

In addition, be provided with return port 23 and 33 respectively in the preceding bottom of refrigerating chamber 20 and the front upper part of refrigerating chamber 30.Cold air arrives evaporimeter 41 by return port 23 and 33 respectively after flowing through refrigerating chamber and refrigerating chamber 20 and 30 circulations.

In the pipeline 22 of refrigerating chamber 20, be provided with an air door 43.Air door 43 is the rectangular slab that rotates around axle 43a, controls the rotation of air door 43 around axle with a switch (not shown) that is arranged in the refrigerating chamber 20.Be supplied to the cold air amount of refrigerating chamber 20 by the rotation control of air door 43.

That is to say,, then be supplied to refrigerating chamber 20 cold air amounts maximum, thus refrigerating chamber 20 is remained on the extremely low temperature below the freezing state if air door 43 is in plumbness A.Yet, if air door 43 is in heeling condition B, reduce the cold air amount of supplying with refrigerating chamber 20, the temperature of refrigerating chamber 20 is elevated to and refrigerating chamber 30 similar temperature.

In the conventional refrigerator of said structure, when making air door tilt to reduce the cold air amount of supplying with refrigerating chamber, since inhomogeneous by the cold air amount between air door and the inner-walls of duct, so can not accurately control the temperature of refrigerating chamber.Because the air by air door has resistance to air door, so be difficult to make air door to arrive predetermined obliquity or predetermined rotational angle, this has just more increased the weight of the problems referred to above.

The present invention is intended to overcome as possible the problems referred to above.
