Description

TECHNICAL FIELD The present invention relates to a refrigerator provided with a third chamber in a refrigerating chamber.

2. Description of the Related Art In recent years, refrigerators have been required to have a function of maintaining a respective optimum storage temperature zone for fresh food such as fish and meat to enable storage for a relatively long period of time without sacrificing freshness. Optimal storage temperature of fish is around -3 ℃, optimum storage temperature of meat is 0 ℃
There is a need for a cryogenic container having a temperature adjusting function of −3 to 0 ° C. that makes it possible to select the vicinity.

A conventional example will be described with reference to FIGS. Reference numeral 1 denotes a refrigerator main body, which is composed of an outer box 2, an inner box 3 and a foamed heat insulating material 4 filled between these boxes.
A refrigerating compartment 7 is formed in the lower part. Reference numeral 8 is a third chamber provided at the top of the refrigerator compartment 7. Reference numeral 9 is a bottom plate that forms the bottom surface of the third chamber 8. Reference numeral 10 is a trim forming the top and bottom sides of the front surface of the third chamber 8.

Reference numeral 11 denotes a temperature adjusting device facing the inner surface of the third chamber 8, which internally has a refrigerating chamber damper opening / closing device 12 (not shown) for controlling the amount of cold air to the refrigerating chamber 7 and cool air to the third chamber 8. A third chamber damper opening / closing device 13 for controlling the quantity is attached. The internal cool air discharge passage 14 connected to the third chamber damper opening / closing device 13 is connected to the internal partition wall discharge passage 15 formed in the internal wall 5. The discharge passage 15 in the partition wall is trimmed
Concatenated with 10. A shutter 16 for adjusting the amount of cold air to the third chamber 8 is attached to the connecting portion with the trim 10. Reference numeral 17 denotes an adjustment button formed integrally with the shutter 16 and protruding on the surface of the trim 10. By moving the adjustment button 17 left and right, the shutter 16 increases or decreases the passage area to adjust the amount of cold air. The cool air that has passed through the shutter 16 is discharged from a discharge port 18 provided in the trim 10 to keep the third chamber at an appropriate temperature. Reference numeral 19 is a door that covers the front opening of the third chamber 8. Convex portions 20 supporting the door 19 are integrally provided on both upper sides of the door 19. On the other hand, the convex portion 20 provided on the door 19 is pivotally supported by the concave portions 21 provided on both sides of the facing trim 10. Reference numeral 22 is a temperature adjustment display printed on the surface of the door 19 at a position facing the adjustment button 17.

The operation of the refrigerator configured as described above will be described below. First, the cool air that has passed through the third chamber damper opening / closing device 13 in the temperature control device 11 reaches the shutter 16 via the cool air discharge passage 14 in the temperature control device and the cool air discharge passage 15 in the partition wall. The cool air that has passed through the shutter 16 is discharged from the discharge port 18 of the trim 10 and cools the inside of the third chamber 8.

There are various kinds of food stored in the third chamber 8, and the suitable temperature varies depending on the food. Therefore, in order to adjust the proper temperature of the stored food, the passage area is increased / decreased by the shutter 16 to adjust the amount of cool air to the third chamber 8. Here, the position where the adjustment button 17 is located at the right end is set to -3 ° C, and the set temperatures of -15 ° C, 0 ° C, and 1 ° C are set as the button moves to the left.

However, in the above-mentioned configuration, even if the adjustment button 17 is adjusted to the adjustment display 22, it is easily misaligned due to vibration of the refrigerator, hitting when taking out food, or the like. However, there is a problem that it is difficult to secure a predetermined set temperature.

The present invention, once you adjust the adjustment button 17 to any position,
Due to vibration of the refrigerator and hits when taking out food,
It is intended to provide a refrigerator in which a positional shift does not occur and a predetermined set temperature can be secured.

Means for Solving the Problem In order to solve the above problems, the present invention provides a rib having a concave portion for positioning the adjustment button at a predetermined set temperature in the shutter portion inside the trim, and sliding the adjustment button facing the rib. A piece whose edge is cut by a kerf is provided on the moving surface, and a projection which engages with the recess of the rib is provided on the rib side of the piece formed by the kerf.

The present invention has the above-described structure, in which the concave portion of the rib inside the trim for adjusting the adjustment button to a predetermined set temperature and the projection formed on the edge cut by the cut groove of the adjustment button are engaged with each other to determine the position of the shutter. This ensures the proper temperature of the food stored in the third chamber without causing a deviation between the set temperature of the adjustment button and the display for adjustment.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 5. In the same configuration as the conventional one, the same reference numerals are given,
Detailed description thereof will be omitted. In the figure, reference numeral 23 is a trim forming the front top and the front side of the third chamber 8. twenty four
Is a rib provided on the shutter 16 portion of the trim 23. 25 is
It is a recess provided in the rib 24. Further, on the sliding surface 26 of the rib 24 facing the concave portion 25, a piece 28 is formed at the position of the adjustment button 17 and the edge of the sliding surface 26 is cut by the cut groove 27. 29
Is a protrusion integrally formed on the rib 24 side of the piece 28. With this structure, when the protrusion 29 of the piece 28 provided on the adjustment button 17 is located in the recess 25 provided in the rib 24 as shown in FIG. 4, the engagement is performed in a state where the spring effect of the piece 28 is not working. is doing. Further, when the protrusion 29 provided on the adjustment button 17 is located in addition to the recess 25 provided on the rib 24, the piece 28 is deformed with the terminal end as a fulcrum as shown by the chain double-dashed line in FIGS. 4 and 5. It is pressed against the rib 24 by the spring effect.

As described above, according to the present embodiment, the concave portion provided in the rib 24
25 and the protrusion 29 of the adjustment button 17 are engaged, the adjustment button
17 is fixed, and when moving adjustment button 17, piece 28
The flexure and the spring effect thereof make pressure contact with the sliding surface 26 of the rib 24, so that the adjustment button 17 can be reliably set at an arbitrary position.

EFFECTS OF THE INVENTION As is clear from the above description, according to the present invention, a door that rotatably opens and closes with convex portions provided on both sides as a fulcrum, a trim that integrally has a concave portion that rotatably supports the door, and a trim. A recess for positioning the adjustment button at a predetermined set temperature in the shutter portion of the trim, which does not include an adjustment button for adjusting the temperature of the third chamber in a part of the above and an adjustment display printed on the door facing the adjustment button. By providing a rib having a ridge, and providing a cut groove on the sliding surface of the adjustment button facing the concave portion, and providing a protrusion that engages with the concave portion of the rib on the rib side of the piece edged by the cut groove. , The adjustment button can be easily adjusted to the preset temperature, and can be set smoothly at any position, and the adjustment button will not be displaced from the setting position due to the vibration of the refrigerator, the taking in and out of food, etc.
The effect that the proper temperature of the food stored in the third chamber 8 can be maintained and the like can be obtained.
