Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator in which a refrigerator room is provided with an upper part of a refrigerator room or another specific refrigerating room, and the temperature of the room is controlled by controlling an inflow amount of cold air in the refrigerator. This is related to the device, and in particular, it is possible to easily control the temperature of each of the refrigerating room and the specific refrigerating room, and the temperature once set in the specific refrigerating room is not related to the operation of changing the temperature inside the refrigerating room. The present invention relates to a temperature control device for a refrigerating room of a refrigerator and a specific refrigerating room that are constantly maintained.

In the past, temperature controllers were attached to the refrigerating compartment and the specific refrigerating compartment so that the room temperature could be adjusted separately.

For example, the refrigerating room is automatically opened and closed depending on the temperature inside the room, and a temperature controller consisting of a shutter and an adjusting shaft for adjusting the opening degree of the shutter and a rotary knob is attached. At the entrance of the incoming cold air, an adjusting plate was installed to adjust the size of the entrance so that the inflow amount of the cold air could be adjusted.

However, as described above, in the normal cold air circulation system, the cold air generated from one evaporator is primarily sent to the refrigerating compartment, and the specific refrigerating compartment is provided with a predetermined amount of cold air entering the refrigerating compartment. Since the system is circulated by omitting the ratio, the temperature inside the specific refrigerating compartment is affected by the temperature inside the refrigerating compartment.

Therefore, in the case of using each temperature controller that is not related to each other as in the conventional example described above, when the temperature inside the refrigerating room is adjusted, the temperature inside the specific refrigerating room is always readjusted. There was also a lot of inconvenience in operation because it was possible to maintain the initial set temperature only in the. On the other hand, even if the temperature inside the refrigerating room is changed, if the temperature inside the specific refrigerating room is not readjusted, the stored food etc. stored in the specific refrigerating room will be read as described below. It was one of the main causes of alteration.

That is, even when the temperature inside the specified refrigerating room is set at the desired temperature while the temperature inside the refrigerating room is set to "medium", only the temperature controller inside the refrigerating room is set to "strong". If placed as "or" weak, the cold air entering the refrigerating room is circulated "strongly" or "weakly".

Therefore, in proportion to this, since cold air is circulated “strongly” or relatively “weakly” in the above-mentioned specific refrigerating room, the temperature inside the room is lower than the temperature initially set and set. Since a low temperature or a high temperature is often generated, the temperature initially set and maintained can be maintained only when the temperature controller of the specific refrigerating compartment is relatively readjusted.

However, in most cases, it is often the case that the temperature inside the refrigerating compartment is changed but the temperature inside the specific refrigerating compartment is forgotten to be readjusted. Points are generated.

SUMMARY OF THE INVENTION An object of the present invention is to provide a temperature control device which is constructed integrally so as to have interrelationship and serves both as a refrigerating compartment and a specific refrigerating compartment in order to solve such a problem.

Therefore, in order to achieve the above-mentioned object, in the present invention, the shutter for automatically flowing in the cold air that is automatically opened and closed according to the temperature of the refrigerating compartment and the opening degree of the shutter are manually adjusted. A temperature controller for an ordinary refrigerating compartment, which constitutes an adjusting shaft and its rotating knob, is adapted to open and close a cold air circulation hole which is linked to the left and right by the rotation operation of the rotating knob and communicates with a specific refrigerating compartment. A first cold air adjusting plate, a separately attached slide knob for setting the temperature of a specific refrigerating compartment, and a second cold air adjusting plate that is interlocked with this slide knob are attached. The second cold air adjusting plate is also moved together at the same time when the cold air adjusting plate is moved, or only the second cold air adjusting plate is selectively movably coupled.

The operation of the present invention by the above means is as follows.

First, the opening degree of the shutter is adjusted by the rotary knob adjustment position as usual, and a certain amount of cold air is circulated to the refrigerating room according to the opening degree of the shutter, and the refrigerating room is controlled to the temperature indicated by the rotary knob. maintain.

In the specific refrigerating compartment, the amount of cold air circulated in the refrigerating compartment is circulated at a predetermined ratio, but at this time, the slide knob for the specific refrigerating compartment is operated to operate the above-mentioned (2) Since the amount of cold air circulated in the specific refrigerating compartment can be controlled by adjusting the cold air regulating plate, the user can set the room temperature of the specific refrigerating compartment to a desired temperature.

After setting the temperature of the room in the specific refrigerating room in this way and then rotating the rotary knob to further change the temperature in the room of the refrigerating room, the opening degree of the shutter is caused by the rotation. The inflow amount of the cold air that is changed and circulated in the refrigerating chamber is also changed, but when the first cold air adjusting plate is moved at the same time when the rotary knob is rotated and the first cold air adjusting plate is moved, the second cold air adjusting plate is moved. The cold air adjusting plate is also moved in the same direction together, so that the amount of cold air circulated in the specific refrigerating compartment is also controlled.

When the cold air circulated in the refrigerating compartment becomes stronger, the cold air circulated in the specific refrigerating compartment becomes relatively weaker. On the contrary, when the cool air circulating in the refrigerating compartment becomes weaker. Maintaining the temperature set at the beginning of the specific refrigerating room by making the cold air circulated in the specific refrigerating room relatively strong, regardless of the temperature change inside the refrigerating room.

A guide portion 4 is formed in the longitudinal direction above and below the rear surface of the first cold air regulating plate 1 having the other cold air passage 2 '.
A second cold air regulating plate 1'having a vertically long shaft hole 3'is connected to one side thereof. Connecting pins 6, 6'at the upper ends of the first and second interlocking levers 5, 5'are fitted and connected to the shaft holes 3, 3'of the first and second cold air regulating plates 1, 1 ', respectively. The first cold air adjusting plate 1 is supported by several supporting pieces 8, 8a, 8b integrally formed on the inner surface of the adjuster cover 7 so as to be movable left and right. The cold air circulation hole 9 can be opened and closed. The center portion 10 of the first interlocking lever 5 is supported by a boss 11 formed on the inner surface of the adjuster cover 7 so as to be swingable, and an arcuate gear 12 formed at the lower end thereof. Is a support portion 13 having a convex shape on the inner surface of the adjuster cover 7.
Rotating knob 1 for ordinary refrigerating room through slot 14 at the top of
5, the first cold air regulating plate 1 is engaged with the gear portion 16 formed on the peripheral surface of the rotary body 5, and the rotary knob 15 for the refrigerating chamber is provided.
It is moved left and right by the rotating action of. The second cold air regulating plate 1'has a central portion 10 'of a second interlocking lever 5'that allows the first cold air regulating plate 1 to move left and right together or independently when it is moved left and right. An arcuate gear 12 ', which is supported by a connecting piece 17 extending from the first cold air adjusting plate 1 and is formed at the lower end of the first cool air adjusting plate 1, extends horizontally from a horizontal elongated hole 18 formed in the adjuster cover 7. It meshes with the gear part 21 of the movable special cold storage slide knob 20. The controller main body 22 to which the above-mentioned controller cover 7 is attached and coupled is provided with a cool air outflow hole 23 on the side of a normal refrigerating chamber at a lower portion thereof and a cool air flow hole 9 of the controller cover 7 at an upper portion thereof. A cold air outflow hole 24 on the side of the specific refrigerating room is formed, and a normal cold air inflow shutter 25 that is automatically opened and closed according to the temperature inside the refrigerator and an opening degree of this shutter 25 are adjusted. It has a usual adjusting shaft 26 and the like connected to the above-mentioned rotary knob 15.

The device of the present invention having the structure described above is mounted between the refrigerating compartment A and the specific refrigerating compartment B and its cold air inflow passage C as shown in FIG. As described above, the shutter 25 automatically opens and closes the cold air inflow passage C according to the temperature inside the refrigerator, and a part of the cold air that flows in depending on the opening degree of the shutter 25 is a cool air outflow hole 23 on the refrigerating chamber side below the controller body 22. Is circulated to the refrigerating compartment A through a part of the remainder, and the cold air outflow hole 24 and the cold air circulating hole 9 on the specific refrigerating compartment side and the first and second cold air regulating plates 1, 1'between them. It is circulated to the specific refrigerating compartment B through the place where the cold air vents 2 and 2'are aligned.

If the rotary knob 15 is rotated in order to change the temperature inside the refrigerating room A, the adjustment shaft 26 rotates as in the normal case and the shutter positioned on the cold air inflow path C side. The opening degree of 25 is changed so that the amount of cold air is adjusted to flow in.

At the same time, since the gear portion 16 of the rotary knob 15 and the arcuate gear 12 at the lower end of the first interlocking lever 5 are meshed with each other, the first interlocking lever 5 moves the first cold air adjusting plate 1 to the left and right, 1 When the cold air conditioning plate 1 moves left and right,
The second interlocking lever 5 for interlocking the second cold air adjusting plate 1 ′ connected thereto has the connecting piece 17 integrally formed with the cold air adjusting plate 1.

The interlocking lever 5'and the slide knob 20 are moved left and right together while maintaining that state.

Therefore, when the opening degree of the shutter 25 is adjusted by rotating the rotary knob 15 as shown in FIG. 3 (a), the inflow amount of cold air becomes stronger or weaker, and the temperature inside the refrigerating compartment is increased. Is adjusted and the size of the cold air flow hole 9 communicating with the specific refrigerating compartment B is adjusted by the action of moving the first and second cold air regulating plates 1 and 1'to the left and right together. The amount of cold air passing through the specific refrigerating compartment B can be adjusted to be relatively “weak” or relatively “strong” by making the above-mentioned value opposite to the opening degree of the shutter 25.

Therefore, the temperature inside the specific refrigerating compartment B can be maintained at the temperature initially set and set despite the fact that the rotary knob 15 is operated to change the temperature inside the refrigerating compartment A. You can do it.

On the other hand, if the temperature inside the specific refrigerating room B is to be changed, as shown in FIG. 3B, if only the sliding knob 20 for the specific refrigerating room is moved to the left or right, The connected second interlocking lever 5'is supported by a connecting piece 17 integrally extended with the first cold air adjusting plate 1 and swings, so that only the second cool air adjusting plate 1'is moved left and right. As a result, the size of the cold air circulation hole 9 of the specific refrigerating compartment is adjusted and the inflow amount of the cold air is also controlled, so that the current state of the refrigerating compartment is maintained as it is and the temperature inside the specific refrigerating compartment is set. You can do it.

Approximately, when the temperature of the room of the specific refrigerating room is set by the above-mentioned method, even if the rotary knob for the refrigerating room is subsequently operated, the temperature of the specific refrigerating room is increased due to the strength of the cold air circulated in the refrigerating room. After all, since the strength is adjusted relatively, the temperature initially set and maintained can be well maintained.

As described above in detail, according to the embodiment of the present invention, it is easy to control the temperature of each of the refrigerating compartment and the specific refrigerating compartment by using only one temperature control device, and particularly, the temperature inside the refrigerating compartment is changed.
