Abstract
An anti-freezing device of a refrigerator cooling air conditioner comprises a driving gear which is driven by a motor, a shaft which moves upward and downward in a shaft duct through the rotation of the driving gear, a first wall and a second wall which are positioned on an outer side of the shaft duct to prevent the water from flowing in the shaft duct, a clapboard which opens or closes a frame cooling air channel through the upward and downward movement of the shaft and a plate spring on top of the clapboard. The plate spring provides a pressure to move the clapboard downward which prevents the supercooling or the insufficient cooling of a cooling chamber.
Description
The present invention relates to a kind of defroster that is used for the motor type cooling air regulator, be used to control the temperature of refrigerator cooling chamber, more particularly, it is the defroster that is used for cooling air regulator of refrigerator, it is included in first and second walls in the spindle guide pipe outside, and stop the current that lead to spindle guide pipe inside by them, prevent the excessively chill and the freezing deficiency of cooling chamber thus.
As Figure 1-3, a common cooling chamber defroster comprises a driving gear 9 that is rotated by motor, rotation by driven wheel 9 makes axle 1 operation up and down in a spindle guide pipe 2, a dividing plate 16 that opens and closes the cooling air channels 14 of framework 12 by moving up and down of axle 1, with a leaf spring 18, it is positioned at dividing plate 16 tops, provides a pressure that dividing plate 16 is moved downward.
At the above-mentioned common defroster that is used for cooling chamber, when motor rotated, driven wheel 9 rotated, and by its rotation axle 1 was moved up and down in spindle guide pipe 2.
If the axle of being operated up and down by driven wheel 91 rises and simultaneously on push away dividing plate 16, the cooling air channels 14 on the framework 12 is opened, and makes the cooling air flow into cooling chamber through a cooling-air duct (end shows).On the other hand, if axle 1 falls, and the pressure of the leaf spring 18 that links to each other with dividing plate 16 tops makes dividing plate 16 rotate simultaneously, and the cooling air channels on the framework 12 is closed, and makes to cool off air and can not flow into cooling chamber.
In common cooling chamber defroster, when using as user's mistake and making water when spindle guide pipe 2 flows into, the cooling air that flows into from the cooling air hose freezes the axle 1 that inserts spindle guide pipe 2, and make cooling chamber can not be controlled in a predetermined temperature, and in cooling chamber excessively chill or freezing deficiency take place.
So, the purpose of this invention is to provide a defroster that is used for cooling air regulator of refrigerator, it is included in first and second walls in the spindle guide pipe outside, and can prevent that water from flowing in the spindle guide pipe, prevents the excessively chill and the freezing deficiency of cooling chamber thus.
Fig. 1 is the plane of common dividing plate;
Fig. 2 is the plane of frame-generic;
The sectional side view of Fig. 3 for connecting between common dividing plate and the framework;
The sectional side view that Fig. 4 connects for the present invention;
Fig. 5 is the perspective view of cooling air regulator defroster of the present invention;
Present invention is described below by most preferred embodiment and with reference to accompanying drawing.
Fig. 4 is a sectional side view of the present invention, has shown the connection between dividing plate and the framework, and there is a leaf spring dividing plate upper end, and the framework lower end connects a driven wheel.Fig. 5 is the perspective view of cooling air regulator defroster of the present invention, has shown that axle inserts in the spindle guide hole, and has formed first and second walls respectively in the outside, spindle guide hole.
The present invention includes a driven wheel 9 that rotates by motor, the rotation of driven wheel 9 makes one 1 and moves up and down in a spindle guide pipe 2, first and second walls 3 and 5 are positioned at spindle guide pipe 2 outsides, to prevent that water from flowing into spindle guide pipe inside, a dividing plate 16 is used for by moving up and down of axle 1 cooling air channels 14 of framework 12 being opened and closed, with a leaf spring 18 that is positioned at dividing plate top, be used to provide a pressure that dividing plate 16 is moved downward.
In addition, when water overflows into first wall 3, on second wall 5, be formed with one group of drainage 7 at regular intervals, and be easy to water is discharged to the outside, water can not flowed in the spindle guide pipe 2.
In above-mentioned the present invention, when motor rotated, driven wheel 9 rotated, and axle 1 is moved up and down in spindle guide pipe 2.If the rotation of driven wheel 9 is risen axle 1 and simultaneously on push away dividing plate 16, the cooling air channels 14 on the framework 12 is opened, and makes the cooling air flow into cooling chamber through cooling air hose (end shows).
In this situation, when water during because of user's inflow cooling chambers such as faulty operation (end shows), first and second walls 3 and 5 prevent that water from flowing in the spindle guide pipe 2.In addition, when water overflowed in the first wall 3, the drainage 7 of water on second wall 5 directly discharged and can not flowed in the spindle guide pipe 2.
On the other hand, if axle 1 falls, and dividing plate 16 is when rotating simultaneously under the pressure of leaf spring 18, and the cooling air channels 14 on the framework 12 is closed, and makes the cooling air can not flow into cooling chamber.
The present invention can have many modification, all in the back among the claim restricted portion.
