[Detailed description of the invention] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of a refrigerator-freezer 1 according to the present invention, in which a push button 3 is provided on the freezer compartment door 2 and a push button 5 is provided on the refrigerator compartment door 4.

FIG. 2 is a diagram in which the door opening mechanism of the present invention is incorporated into the case 6. In this figure, 7 is a pin (A) that is slidably attached to the case 6, one end 7a contacts a receiving part (A) 9 fixed to a side wall 8a of the refrigerator compartment 8, which will be described later, and the other end 7b is in contact with one end 10a of the cam plate (A) 10. The cam plate (A) 10 is fixed to the case 6 and rotatably mounted on a letter shaft 11.

Other end 1. A hole 10C is provided in Ob into which the bent portion 12a of the rod 12 is inserted. mouth. The other end bent portion 12 ( ) of the rad 12 is inserted into a hole 1 - 3 b provided in one end 13 a of the cam plate (B) 13. 0, it is rotatably mounted on a shaft 14 fixed to the case 6.A torsion spring 15 or a cam plate (B) 13 is biased clockwise on the shaft 14.The cam The other end 13C of the plate (B) 13 has a cylindrical shape, and the compression coil spring 1 attached to the pier (B)] 6
A spring seat 18, which is slidably attached to a pin (B) 1.6 for smoothly compressing the spring 7, is pressed into contact with the spring seat 18. The pin (B) 16 is slidably attached to the case 6, and includes a receiving part 16a for the compression coil spring 17, a receiving part for return operation], 6b, and a groove part 16 for regulating sliding movement.
C is provided. Further, one end 16d is in contact with a receiving portion (B) 19 fixed to a side wall of the refrigerator compartment 8, which will be described later.

20 is a regulating plate with one end 20 in the groove 16C of the pin (B) 16.
a, the other end 20b has a hole 20C, and the L potato odor 21
One end 21a of is inserted. The L potato odor 21 is rotatably mounted on a shaft 22 fixed to the case 6, and biased clockwise by a torsion spring 23 attached to the shaft 22. ■The other end 211 of the 7-character potato odor 1 is in contact with the foot 5a of the push button 5 provided on the front of the refrigerator compartment door 4.

Figure 3 is a cross-sectional view of a part of the refrigerator compartment door 4 that is installed in this machine. It is slidably attached to a decorative plate 24 fixed to the door 4, and its shaft 5a is prevented from being removed with an E ring 25.

FIG. 4 is a cross-sectional view of the attachment part of this mechanism of the refrigerator compartment 1 and the aligner 26. - of the side wall 27.28 of the door liner 26
The first part 27a and 28 are attached to accommodate the pin attachment part of the case 6, and are attached to the receiving part (A) 9, the receiving part (B) 19, the pin (A) 7, and the pin (B) provided in the refrigerator compartment 8, which will be described later. ) 16 are provided with holes (A) and (B) 29.30 for contacting one end thereof. Figure 5 is the A-A cross section of Figure 1, and the installation is in case 6.
, is a diagram showing a state in which the door liner 26 is assembled into the refrigerating compartment door 4, and is a diagram showing a state in which the refrigerating compartment door 4 is closed. For installation, the case 6 is fixed using the implanted door liner attachment part 3. On the side wall 8a inside the refrigerator compartment 8, there is a
Pin (A) 7 and pier (B) 16 attached to H case 6
A receiving part (A) 9 and a receiving part (B) 19 are fixed at positions corresponding to the above.

Consisting of the above configuration, according to the present invention, the components of the door opening mechanism are assembled into the case 6 as described above, and the door liner salt (1 part 31) of the refrigerator compartment door 4 is fixed as a component part. The shaft 5a of the push button 5 provided on the front side of the refrigerator compartment door 4 engages with one end of the Nozomi L potato odor 21 in the case 6.After that, if the door liner 26 is attached, the refrigerator compartment 8 will perform its role without any trouble. Also, it becomes.

Next, its operation will be explained. Pin (A) installed on the door hinge side
) 7 protrudes when the door is opened, as shown in FIG. 6, by a torsion spring 15 attached to the shaft 1 of the cam plate (B) 13. Conversely, the pin (B) 1.6 provided on the opposite side of the hinge is rotated by the rotation of the cam plate (B) 13 by the torsion spring 15.
At one end 13C of cam plate (B) 1.3, pin (B) 1.6
The receiving portion 16b for return operation provided in is pushed down, one end 20a of the regulating plate 20 is inserted into the groove portion 16C, and the sliding motion is regulated in a retracted state. This door open state (3rd
When the door is opened from the position shown in the figure, one end 7a of the pin (A) 7 hits a receiving portion 9 fixed in the refrigerator compartment 8, and the pin (A) 7 is retracted. This operation causes the other end 7 of peer (A) 7 to
The cam plate (A)]0 in contact with b rotates. As a result of this rotation, the rod 12 connecting the cam plate (A) 10 and the cam plate (B) 13 is pulled in the HAKAM & (A) I O direction, and the cam plate (B) 13 is rotated counterclockwise. let When the cam plate (B) 13 rotates, one end of it], 3
The spring seat 18 is slid at C to compress the compression coil spring 17. At this time, since the active movement of the pin (B) 16 is restricted by the limit plate 20, the compression coil spring 17 remains compressed.

Next, when the door is closed (Fig. 5), to open the door, finger the push button 5 and press it lightly.
By pushing one end 21h of 1 and rotating the L potato odor 21, the regulation plate 2o slides toward the L sweet potato odor 21 side by the other end 21a of the L sweet potato odor 21. This 1: Due to the sliding action, the pin (B
) I 6 ノ 1 Ill; 9 (5) 6 c and the one end 20a of the regulating plate 20 are disengaged.

Therefore, the pushing force of the push button is 16 pins (B) (as it simply releases the lock, a light operating force is sufficient).
Since the restriction has been lifted, the retainer (B) 19 fixed in the refrigerator compartment 8 is pushed out by the force stored in the compression coil spring 17 at one end 16 ( ).

This reaction force cancels the holding force caused by the magnetic force of the magnet gasket, and further opens the door with spring force. The door opens at an angle that is the inertia of the door. After the door opens, all you have to do is place your hand on the corner of the door and open it at the angle you want.

Also, to close the door from this open state, simply push the door lightly. The force needed to cancel the magnetic force of the magnets and locks and open them is stored in the compression coil 17, but the driving force that compresses the compression coil 17 is received by the pin (A) 6 provided on the hinge side. The pin (A) 7 is located at a close distance from the hinge, and the corner where the hand is placed to close the door can close the door with the smallest force from the hinge. In other words, it is an easy-to-handle door opening mechanism that allows the door to be opened by lightly pushing the button with the large holding force of the magnetic force of the Macnet seal, and can be closed with a small force when closing 111. - As explained above, according to the present invention, the components other than the push button are assembled into the case, and the case is fixed to the door. It is easy to assemble, and in the event of a failure, it can be easily repaired by making it into a repair part. In addition, the door opening mechanism of the present invention does not use expensive electrical parts such as electromagnetic solenoids, and is an inexpensive mechanism that utilizes the distance ratio from the door hinge. is considered large.
