The present invention relates to a device for controlling the temperature and humidity of the vegetable chamber of the refrigerator, and more particularly, to adjust the temperature and humidity in the vegetable chamber in multiple stages.

In general, the refrigerator is largely composed of a freezer compartment for freezing food and a refrigerating compartment for refrigerating. A vegetable compartment 2 is formed below the refrigerating compartment to be divided into a refrigerating compartment by a cover 1, and a refrigerating compartment and a vegetable compartment on the rear wall of the refrigerating compartment. (2) The duct (3) is installed to guide the cold air outflow into the cover (1) is provided with a control device to adjust the temperature and humidity in the vegetable box (14).

Conventional vegetable room temperature and humidity control device is formed in the rear of the cover 1 is formed as shown in Figures 1 to 3 of the accompanying drawings, the cold air discharged from the duct (3) installed on the rear wall of the refrigerating chamber vegetables Supply hole (1a) to supply to the box 14, discharge hole (1b) formed in front of the cover 1 to discharge the cold air in the vegetable box 14 to the outside, and the front of the cover (1) Is installed on the top plate is composed of cold air discharge control means for controlling the cold air discharge in the vegetable box (14).

In the cold air discharge control means is a moving plate 21 installed to close the discharge hole (1a) in the front inner side of the cover (1), and is inserted so as to protrude outward in the center of the moving plate 21 to the left and right The adjusting knob 22 and the movable plate 21 are formed to have different diameters to the left and right centers of the adjusting knob 22 to move the discharge plate 1b according to the movement of the movable plate 21. It consists of the left hole 23 and the right hole 23a which can control the quantity of cold air discharged | emitted to the inside.

Accordingly, when vegetables or fruits are put into the vegetable box 14 (hereinafter, collectively referred to as “fruits and vegetables”), the vegetable box 14 is pushed into the vegetable compartment 2 and the device is operated to cool the air generated by the refrigerant cycle. It flows out through the duct 3 installed in the rear wall of the refrigerating chamber.

In this way, the cold air which flowed out from the duct 3 is supplied into the vegetable chamber 2 through the supply hole 1a formed in the back of the cover 1, and this supplied cold air is inside the vegetable box 14 of the said vegetable chamber 2 After circulating through the discharge hole (1b) formed in front of the cover (1) is discharged, when the user wants to adjust the temperature and humidity in the vegetable chamber as needed, the user holding the control knob 22 by hand What is necessary is just to move the moving plate 21 to the left or the right.

That is, when the adjustment knob 22 is pushed to the left side, the movable plate 21 installed inside the front top plate of the cover 1 is slid to the left, so that the movable knob 21 is formed on the right side of the movable plate 21 about the adjustable knob 22. And the number of right holes overlapping with the discharge hole 1b among the plurality of right holes 23a having a relatively large diameter, and the discharge hole 1b among the plurality of left holes 23 having a smaller diameter than the right hole 23a. The number of left holes overlapping with the water is reduced, and thus the amount of cold air in the vegetable box 14 discharged through the discharge hole 1b increases, so that the temperature in the vegetable box increases and the humidity decreases.

In addition, when the adjustment knob 22 is pushed to the right, the movable plate 21 is slid to the right, so that the movable plate 21 is formed on the left side of the movable plate 21 about the adjustment knob 22 and the diameter is relatively smaller than that of the right hole 23a. The number of left holes overlapping with the discharge hole 1b in the plurality of left holes 23 increases, and the number of right holes overlapping with the discharge hole 1b in the plurality of right holes 23a becomes smaller, thereby allowing the discharge holes 1b. The amount of cold air in the vegetable box 14 discharged through) decreases, and the temperature in the vegetable box decreases and the humidity increases.

Temperature and humidity control in the vegetable box 14 described above is possible because the amount of cold air supplied into the vegetable room is always constant and the amount of cold air discharged from the vegetable box 14 is controlled.

However, the conventional devices such as the temperature and humidity are made at the same time according to the amount of cold air discharged from the vegetable box, so the user can not adjust the temperature and humidity according to the type of fruit and vegetables stored in the vegetable box exactly as needed to freshen the fruits and vegetables for a long time There was a problem that could not be maintained.

The present invention has been devised to solve the above-mentioned problems, and the user can separately control the amount of cold air supplied into the vegetable box and the amount of cold air discharged from the vegetable box, according to the type of fruits and vegetables stored in the vegetable box. The purpose is to control the humidity in multiple stages as needed.

Knob (9) consisting of a rack (8) for rotating the lever (5) forward and reverse rotation, the adjusting means is axially coupled to the lower plate of the cover (1), the handle piece (9a) integrally formed on the upper surface And a pinion (10) formed at the bottom of the knob and engaged with the rack (8) formed at the lever (5), and a wing piece (11) formed at the top of the knob (9) and having an incision groove (11a) in one axis. ), A knob cover 12 supported on an upper surface of the wing piece so as to be rotatable separately from the knob 9, and a knob cover 12 formed on the knob cover 12. Rotation during the day as superposed on a recess (11a) and selectively formed reorganization (11) consists of a plurality of holes 13 to control the cool air discharge in the vegetable compartment (2).

Referring to the operation, effects of the present invention configured as described above are as follows.

After putting the fruits and vegetables in the vegetable box 14 and then pushing the vegetable box into the vegetable compartment (2) and operating the device, the cold air flows out of the duct (3) installed on the rear wall of the refrigerating compartment and formed in the cover (1a) After going through the vegetable box 14 through the vegetable box (14) through the discharge hole (1b) formed in the cover 1 is discharged again to the outside of the vegetable box (14), at this time the user (14) When adjusting the amount of cold air supplied into the outside or the amount of cold air discharged to the outside from the vegetable chamber as necessary, it is possible to operate the control means axially coupled so that the upper portion protrudes to the outside inside the front of the cover (1).

That is, when the user grasps the handle piece 9a formed on the upper surface of the knob 9 constituting the adjusting means by hand and rotates it clockwise in the drawing, the rotational force is formed on the lower portion of the knob 9. Since the lever 5 is transmitted to the lever 5 through the rack 8, the lever 5 rotates counterclockwise in the drawing about the hinge axis. At this time, one side guide of the opening and closing plate 6 formed at one end of the lever 5 is guided. Since the ball 7 overlaps the guide passage 4 formed at the rear inner side of the cover 1, the air is opened and the cold air flowing out from the duct 3 is continuously connected to the guide passage 4 and the guide hole 7. The guide is supplied to the vegetable box 14 through the supply hole (1a).

It is understood that the amount of cold air supplied into the vegetable box 14 may vary accordingly.

In addition, when the user rotates the knob cover 12 that constitutes the adjustment means in the clockwise or counterclockwise direction on the drawing, the knob cover 12 is rotatable separately from the wing piece 11 formed on the top of the knob 9. When the cutting groove 11a formed in the wing piece 11 and the plurality of holes 13 formed in the knob cover 12 overlap, the cold air in the vegetable box is formed through the discharge hole 1b formed in the cover 1. When the plurality of holes 13 formed in the cutting hole 11a formed in the wing piece 11 and the knob cover 12 are alternately discharged to the outside under the guidance of the cutting groove 11a and the hole 13, Cold air in the box is not discharged to the outside.

In the above description, the overlapping area of the guide hole 11a of the wing piece 11 formed in the knob 9 and the plurality of holes 13 formed in the knob cover 12 varies according to the rotation amount of the knob cover 12. It can also be understood that the amount of cold air discharged in the vegetable box 14 can be changed accordingly.

Therefore, as the amount of cold air supplied into the vegetable box increases, the temperature of the vegetable box falls, and as the amount of cold air discharged from the vegetable box increases, the humidity in the vegetable box falls.
