Refrigerator Piping System of Refrigerator

1 is a refrigeration cycle diagram showing the configuration of the present invention.

2 is a trauma perspective view in which the in-phase heating element is disposed.

3 is a perspective view seen from the inner side of the trauma of the portion of the groove of the heating element that is the in-phase.

4 is a cross-sectional view of a state filled with in-phase insulation.

The present invention relates to a structure in which the high pressure side refrigerant pipe of the refrigerating cycle is arranged at the periphery of the opening of the main body of the refrigerator, which facilitates the assembling process and lowers the refrigerant to an appropriate temperature at the side wall before circulating the periphery of the front system. will be.

When the present invention is described in detail with reference to the accompanying drawings, (1) is an electric compressor (2) is a defrosting liquid evaporation pipe of the cooler (7), (3) the flock of the refrigerator (8) 8A) A dew-proof anti-heating agent disposed at the periphery, (4) is a condenser, (5) is a dryer, (6) is a capillary for pressure reduction, and (7) is a cooler. The dew attachment prevention heating body of (3) is arrange | positioned so that the edge part of 8 A of front openings of the outer case 8 of the refrigerator may be heated. That is, the dew-proof anti-heating body 3 disposed in the U-shaped groove 11 formed as an outer flange 10 which is a packing contact surface of a refrigerator door (not shown) bent inwardly, and wound in the groove 11. ) Distributes the refrigerant inlet pipe 3C and the outlet pipe 3D along the side wall of the outer box 8 or the inner surface (side wall in the drawing) of the ceiling wall or bottom wall so as to extend out of the outer box 8.

At this time, there is an obstacle because there is an inner flange 10, the inner flange 10 to reach the inner surface of the side wall of the trauma (8) The hole 12 is provided, and the heating body 3 is fixed substantially so as to drop the heating body 3 from the nodule 13 to the locking portion 14. The width W of the heating body 3 is a width W that can be inserted into the U-shaped groove 11 of the left and right side walls of the trauma, and the height H is also fitted into the U-shaped groove 11 of the ceiling and the bottom wall. As the height H, the left wall side in the drawing is bent to the rear of the heating body 3, so that it can be reduced. Insertion method of the heating body 3 into the groove 11 inserts the cross section of one heating body 3 into the bottom wall hole 19, and in the figure, the locking part in the nodal part 13 of the upper hole 12 is shown. Inserting and locking the heating body 3 of the side inserted into the said bottom wall hole 19 in 14, and inserting the heating body 3 so that it may circulate in the groove 11 of a ceiling wall, a right wall, and a bottom wall, Finally, the end face of the heating element 3 of the other side is inserted into the other bottom wall hole 19, and the lower end of the hole 12 located on the other inner flange 10 is lifted up slightly. The excretion of the heating body 3 in the groove 11 falling from the engagement portion 13 to the locking portion 14 is substantially fixed.

Then, the horizontal portion 3A is pressed in the direction of the arrow in FIG. 3 to be in contact with the inner surface of the trauma 8, and fixed to the inner surface of the trauma with a tape 15 or polyethylene film or welding, and the vertical portion 3B is also horizontal. The part 3A is fixed or press-contacted to the inner surface by the same treatment, the holes 19 and 19 are sealed with a putty or the like, and the elastic insulating material 17 such as maltpurene is pressed in the groove 11. (I) and foaming-fills the heat insulating material 18 in the space formed by the outer wound 8 and the inner wound 16 by engaging the inner wound 16 with the outer wound 8.

As described above, the high-pressure side pipe of the refrigerant pipe of the refrigeration cycle is disposed in the dew-adhesive heating agent that is arranged to heat the front part edge of the refrigerator outer box 8, and extends from the dew-attached heater 3. The inlet pipe 3C and the outlet which discharged the outlet pipe 3D of the coolant to the inner surface of the outer wall in a heat exchange relationship from the inlet pipe 3C of the coolant to the heating body 3 and the heating body 3 and were electrically discharged. The refrigerant passing through the inlet pipe 3C, which was formed by extending from the hole 19 of the trauma bottom wall provided with the tube 3D at the traumatic side wall surface side to the trauma part, radiates heat from the trauma 8 so that the electric heating element is heated. The temperature of the temperature drops to an appropriate temperature, so that the periphery of the opening 8A can be warmed to a predetermined temperature, while the refrigerant passing through the outlet pipe 3D also radiates to the outer box 8, so that the condenser 4 installed outside the box. Can be made small, and the inlet pipe 3C and the outlet pipe 3D Since it extends outward from the hole 19 of the trauma bottom wall provided on the outer wall 8 side wall surface side where it is arranged, when the heating body 3 is assembled to the trauma 8, the inlet pipe 3C and the outlet pipe ( Since 3D) can work while moving along the trauma side wall, it is easy to work and has no effect of construction, while the inlet pipe 3C and the outlet pipe 3B are formed by the holes 19 of the trauma bottom wall. Since it can be maintained along the outer side wall surface, the installation of the inlet and outlet pipes on the outer side wall can be made extremely simple. In addition, in some cases, an electric compressor is provided with lubricating oil and a cooling pipe. A refrigeration cycle conventionally requires an auxiliary capacitor, and has been used to cool the electric compressor as a refrigerant cooled by the auxiliary capacitor. However, in the present invention, the auxiliary condenser is replaced with a dew preventing prevention heating element and thereupon. It can be performed with the device on the pipe wall.

In addition, it extends from the dew-proof anti-heating body formed in the internal flanges of the grooves of the ceiling wall, the bottom wall, and the right wall, and the pipes are fixed to the respective walls by tape or the like. Since it solidifies and press-contacts a wall surface, heat exchange efficiency improves, and a heating body is simply arrange | positioned in a groove | channel by simple notching to an internal flange, and workability is also favorable.
