Description

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

FIG. 1 is a front view of a refrigerated floor 1 according to the invention, in which a push button 3 is provided in front of a door 2. FIG. 2 is a sectional view taken along the line A-A in FIG. 1, showing the door opening mechanism of the present invention in a state where the door 2vc is closed. In this figure, reference numeral 4 denotes a door liner, which is attached to the upper parts 5a, 6a of the side walls 5.6 of the door liner, and is attached to the hinge/receiving portions 7a and 7a of the case 7, respectively. +3 fully housed, guide protrusion 8 formed on the upper inner side of the door to facilitate cold air circulation
For installation, fit it into case 7's connection ffB7c'. 9 is an egg case installed in the upper part of the door liner. In the above installation, various mechanical parts are attached to the case, and 1.
0 is a pin (A) attached so as to be freely slidable;
The other end 10b is in contact with the one end 13a of the cam plate (A> 13 (7). The cam plate (A) 13 is fixed to the goosef and is rotatably mounted on the shaft 14. The other end 13b has a hole i30 inserted into the bent part 152 of the rod 15.The other end bent part 15b of the rod 15 has a cam plate (-4r 16a of B116
A hole 16bvC provided with a VC is inserted.

Similar to the cam plate (A) 13, the cam plate (B) 16 is attached to the case 7 fixed to the 111117 for automatic rotation. Axis 17+'? : The torsion spring 18 is biasing the cam plate (B) 16 (i7 clockwise.Other than the cam plate (B) 16 J: Product 16 c is circular and has three
Pi/(B) Attached to 19 L/j A pin for smoothly compressing the compression coil bypass 20. The pi/socket 21, which is slidably attached to the pin (B) 19, is pressed into contact with the pin. The pin (B) 19 U is slidably attached to the case 7, and the receiving part 19a of the compression coil spring 20,
Receiving part 19b for return operation, groove part 19c for regulating sliding movement
is provided. One end 19d of the housing is in contact with a receiving part (B) 22 fixed to the wall of the refrigerator compartment 11.

23 is a regulating plate and pin FB) One end 2 is attached to the groove 19C of 19.
3a, the other end 23b has hole 23C fully, L dictionary 2
-yiii24 a Jz of 4 is inserted. The L-shape
Therefore, it is biased in one direction. The curved end 24b of the L dictionary 24 is in contact with the shaft 3a of the 'lit' button 3 facing the ji2 body.

The system has the above configuration, and its operation will be fully explained next.

The pin (A) 10 provided with the v'c for the hole is attached to the cam plate (13
) The torsion pie 18 attached to the four spout 17 of 16 protrudes when the door is opened, as shown in Fig. 3. On the other hand, Pino FB installed on the opposite side of the hinge) 19 is the QjiQ spring 18
Due to the rotational movement of the cam plate (B) lfj, the cam plate (
At one end 16c of the Bl 16, a pin (B) 19K is provided to receive the return m11 action receiving part 19b. is in a regulated and retracted state. When the door is closed from this open state (Fig. 3), the pin (A) 10 -X
glOa hits the receiving part 12 fixed in the refrigerator compartment 11, and the pin (A) 10 is not retracted. This action causes the pin (A) 10 and the Kamui arm (
A+ 13 rotates. This rotation causes the cam plate (A) to
13 and the cam (the rod 15 connecting the river 16 is tensile to the cam plate (A) 130,000 times 1-) f'L, the cam plate (B)
Rotate 16 teeth counterclockwise g1 million times. Cam plate (B) 1
When 6 turns and moves, the spring catch 2 at 4i 16 c
1? The compression coil spring 20 is compressed by sliding. At this time, the sliding movement of the pinot (B) 19 is regulated by the regulating plate 23]
Since it has 11 points, the compression coil pie 20 stays compressed and compact.

Next, press button 3 to open the door while it is closed (Figure 2).
When pressed lightly with a finger, the push button shaft 3a slides to push one end 24b of the 17-character dictionary 24, and the L-character 2''4 rotates. 24a, it slides to the L-jiden 24ill11. By this sliding operation, the groove 19c of the pin (Bl 19) and one end 23a of the rule 11i11 plate 23 are disengaged. Therefore, the pressing force of the push button is (M) Since the latch is simply removed, a light operating force is sufficient.

Due to the lifting of regulations, compression coil springs 20
19 dV at all ends of the receiving part (B) 22, which was stuck inside the refrigerator compartment 11 and tried to protrude due to the battery being stored in the refrigerator. :.

I push it away. This reaction force cancels out the holding force caused by the force V of the red gasket, and opens the door with the remaining force. In addition, the angle that is the inertia of the door opens more than this stupid VC. After the door opens, open it by placing your hand on the corner of the VC sin that you want to open.

Well, in order to close the door from this open book, all you have to do is press your lungs lightly and it will close. Magnetic force of magnet packskin? The force needed to compress and open the compression coil spring 20 is stored in the compression coil spring 20, but the driving force that compresses the compression coil spring 20 is the pin provided on the hinge (A+10 hits the receiving part (A+12) and is retracted). Pin (A) 10 is located at a close distance from the hinge, and βi fully closed AVc hand f. The door can be closed with a small amount of force due to the tacking ratio.Furthermore, from the position where the door is opened 90 degrees, the above-mentioned -
Even if you put your hand on the corner and push it away, it will close enough.

As explained above, when opening a door with a magnetic seal, you can open it by lightly pressing the push button, and when closing it, you can use a small knife to close the door.This door opening mechanism is easy to handle. All installations are housed in a V-case, and the shape of the door light (side wall, guide protrusion + (il-uch) is used to fit the door case into the existing egg case on the upper part of the liner. It is.

The uninvented door-opening mechanism does not cause any trouble when it is assembled/inserted, and it is safe because it does not require expensive parts such as electromagnetic solenoids. Since the attachment is built into the case and the LeC attachment is a mechanism that operates smoothly, productivity is also high. It also has great flexibility, such as being able to use an automatic oven with just a few steps.
-IJ'in can be cut in one step, and the refrigerator binding C design incorporated in the system can be unified, making it optimal. Furthermore, there are many other benefits such as improved handling properties, such as the packaging size being reduced when transported in a refrigerator or stored in a neck cabinet, reducing transportation costs, and the effects are very large.
