Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a refrigerator provided with a compartment inside a storage chamber, which is kept at a constant temperature different from that of the storage chamber.

2. Description of the Related Art Hereinafter, description will be given with reference to FIGS. 4, 5, 6, and 7. 1 is a storage room, 2 is a compartment, 3 is a frame-shaped frame member provided around the front of the compartment 2, 4 is a door pivotally supported by the frame member 3, and 5 is the bottom of the compartment 2. A bottom plate, 6 is a temperature control device, and a damper thermostat 7 is housed inside the temperature control device 6, and an air passage 8 for circulating cold air continuously passes through the inside of the partition wall 9 and the frame member 3 It communicates with the duct 10 provided in the. A shutter 11 for adjusting the amount of cold air is incorporated in the duct 10, and by sliding it left and right, the opening area is changed to change the amount of cold air discharged from the discharge hole 12 to adjust the temperature of the compartment 2. Has become. As described above, the door 4 is rotatably supported by the frame member 3, but the recesses 13 are provided on the upper left and right sides of the frame member 3, while the convex portions 14 are provided on the upper left and right sides of the door 4. Is provided, and the convex portion 14 is inserted into the concave portion 13 of the frame member 3 to rotate. The frame member 3 is screwed by tapping screws 16 on the lower portions of the left and right sides, and the upper portion thereof is locked and fixed by a protrusion 17 provided on the top surface of the storage chamber 1.

In the above-mentioned configuration, when the food or the like stored in the compartment 4 is put in or taken out, it is made possible by rotating the door 4 upward around the convex portion 13 and opening it. Is indicated by a chain double-dashed line. After the food is taken in and out, when the hand is released from the door 4, it is rotated downward due to its own weight and closed. On the other hand, the cold air flowing through the duct 10 is guided to the frame member 3 with its opening area adjusted by the sliding of the shutter 11 left and right and the amount of cold air adjusted. The sliding state of the shutter 11 is shown by a chain double-dashed line. This cold air is further discharged from the discharge hole 12 to the compartment 2.
The inside is maintained at a predetermined temperature.

However, although the frame member 3 is fixed by the tapping screw 16 in the above-mentioned structure, the protrusion 17 provided on the top surface of the storage chamber 1 which is the other fixing structure is undercut. Since it is made of a vacuum material, it is difficult to obtain a secure lock because the height of the protrusions is low and the shape is sagging. Therefore, when the shutter 11 is held and pulled toward the front, or when the door 4 is rotated upward and pulled toward the front, the frame member 3 has the protrusion 17 at the upper part around the tapping screw 16. It can get out of hand. As a result, the frame member 3 comes off and rattles, resulting in deterioration of quality such that it cannot withstand normal use. Further, the duct 10 and the frame member 3 lose continuity and cold air cannot be smoothly introduced into the compartment 2 so that the compartment 2 cannot be divided. The chamber 2 has a quality problem such that a predetermined temperature cannot be obtained and the shutter 11 does not operate smoothly.

The present invention solves the above-mentioned problems of the conventional example. A concave portion is provided in the upper left and right sides of the frame member, a hole is formed in the deepest portion of the concave portion, and the concave portion is screwed to the wall surface of the storage chamber and the door is inserted into the concave portion. By inserting and pivoting the convex parts provided on the upper left and right sides of the rotatably, the fixed state of the frame member is always maintained, and the cool air is appropriately supplied to maintain the predetermined temperature. It is intended to provide a refrigerator having a desired cooling performance.

Means for Solving the Problems In order to solve the above problems, the present invention provides a recess at the upper left and right sides of a frame member, makes a hole in the innermost part of the recess, and screws it into the wall surface of the storage chamber, The convex portions provided on the upper left and right sides of the door are inserted and pivotally supported so as to be rotatable.

The present invention has the above-mentioned structure and maintains a reliable fixed state without causing displacement or rattling of the frame member even if the door is pulled upward or the shutter is pulled.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3, but the same parts as those of the conventional example will be designated by the same reference numerals and detailed description thereof will be omitted.

A convex portion 14 is provided on the upper left and right sides of the door 4, and the convex portion 14
The reference numeral 14 is inserted into recesses 17 provided on the upper right and left sides of the frame member 3, whereby the door 4 is rotatably supported by the frame member 3. The frame member 3 has a small hole at the innermost portion of the recess 17.
18 is provided and is screwed to the inner wall surface 19 of the storage chamber 1 with a tapping screw 16. Further, another recess is provided in the lower left and right sides of the frame member 3, and a small hole 21 is formed in the innermost part of the lower recess 20. The tapping screw 22 is screwed on similarly to the upper recess 17, and the frame member 3 is thus fixed. Further, the top surface of the storage chamber 1 is a flat surface without any protrusion or the like, and is in contact with the upper portion 23 of the frame member 3.

In the above-mentioned configuration, when the stored food is taken in and out, it is made possible by rotating the convex portion 14 of the door 4 upward to open it, and the state shown by the chain double-dashed line Even if the door 4 is opened and pulled forward, this is the point of application of the tensile load at that time. Since the convex portion 14 and the concave portion 18 to which the frame member 3 is fixed are aligned,
The moment of force does not work, and the force for rotating the lower recess 20 of the frame member 3 does not work. That is, no force acts on the tapping screw 22 in the shearing direction of the screw, but only on the "whip" from the inner wall surface 19 of the storage chamber 1 of the frame member 3, that is, in the axial direction of the screw, and it is fixed with a slight fastening force. ing. Similarly, since the moment of force does not act, the rotating force does not act on the upper portion 23 of the frame member 3, and the forward force does not act and the behavior does not occur.

Further, even when the shutter 11 is pulled, the frame member 3 does not behave because it is fixed at the two locations of the tapping screws 16 and 22 at the upper and lower portions of the left and right, respectively.

As described above, according to the present invention, the door or the shutter is pulled by tapping the innermost part of the concave part of the frame member that inserts the convex part of the door and the lower part with tapping screws. However, the frame member does not come off and rattling does not occur. Therefore, it is possible to ensure continuity with the duct, cool air can be smoothly blown to the compartment, and an appropriate temperature can be maintained without degrading the quality such that it cannot withstand normal use. Moreover, since the smooth and free movement of the shutter does not hinder the operation, it is possible to set the temperature arbitrarily by the user. Further, since the upper tapping screw is inserted through the convex portion of the door so as to cover this portion, it is not exposed to the outside and does not give a strange feeling.
