The present invention relates to an improvement of a cooling apparatus for installing a direct cooling cooler in a cooling chamber.

Conventionally, in a cooling device such as a refrigerator, a flat-type direct cooling cooler is installed in addition to an intercooling cooler that circulates cold air in a freezing chamber by a fan blowing action. There is provided a configuration which allows for rapid deicing and freezing of food by a cold chiller.

By the way, in recent years, the refrigerator tends to enlarge both the upper freezer compartment and the lower refrigerator compartment according to the user's request, and the freezer compartment installed at the upper side is located at a higher position.

Therefore, it is preferable to install the ice tray in the bottom of the freezer compartment so that it is easy to put the ice tray in the freezer compartment. As a result, a space is inevitably created between the lower surface of the direct cooling cooler and the bottom of the freezing chamber, and there is a problem of invading and freezing into the space from an ice tray.

The present invention has been made in view of the above circumstances, and its object is to ensure that even if a direct cooling cooler is installed at the bottom of the freezer compartment, water can freely be prevented from entering the space between the lower surface of the direct cooling cooler and the freezer compartment bottom. To provide a cooling device.

The present invention, for example, partitions the inside of the refrigerating compartment body into a freezer compartment and another storage compartment, and forms a ventilation path on the partition wall forming the bottom of the freezer compartment to return the above-mentioned cold air in the freezer compartment to the intercooling cooler, thereby surrounding the upper surface of the above-described partition wall. The groove is formed in the flange to form a bulge that forms a frame as a whole, and a flat-shaped direct cooler is installed on the bulge to fit the flange around the cooler. It is characterized by forming a communication hole which fits into the groove and communicates with the above-mentioned ventilation path in the flange fitting groove, and the ventilation path is formed through the groove and the communication hole that flange-fit the water dropped on the direct cooling cooler. As it flows, water forms the lower surface of the direct cooler and the top of the wall, which is the bottom of the freezer compartment. It is to prevent intrusion into space.

An embodiment of the present invention will now be described with reference to FIGS. 1 to 3.

The water receiving place 13 which is located and opens upward is formed.

"14" is a member of a heat insulating membrane installed inside the freezer compartment 6, which forms the cooler duct 15 together with the rear wall of the inner box 3, and in the cooler duct 15, the above-mentioned water receiving point 13 ) Is located above and is provided with an intercooling cooler (16).

In addition, an opening 17 is formed in the upper end of the partition member 14, and a fan 19 driven by the driving motor 18 is provided in the opening 17.

“20” is a plastic makeup cover, and the discharge port 21 formed of several holes is formed in the upper end, the middle and the lower end, respectively.

The makeup cover 20 is provided so as to form a cold air passage 22 in front of each of the above-described diaphragms 14 so as to form the rear wall of the freezing chamber 6.

Then, as shown in FIG. 2, the upper cover 9, which is the upper surface of the partition wall 5 described above, has a jaw portion 23 that forms a rectangular frame shape together with the jaw 23 that forms part of the protrusion portion of the rear end portion. Is formed, and flange fitting grooves 25 are formed around the left, right, and front sides of the protruding portion 24.

In front of the flange fitting groove 25, as shown in FIG. 3, three (only one) communication holes (shown only one) of the engagement holes communicating with the above-described ventilation path 12 (FIG. 1) ( 26 are formed at equal intervals, and as shown in Fig. 2, the jaws 23 of the upper cover 9 are provided with three engaging crots 27 prominently corresponding to these communication holes 26.

"28" is a direct cooling cooler that forms a rectangular flat shape, and a coolant pipe 29 is provided in a sigzag shape at the bottom thereof.

In addition, the left side, the right side, and the front circumferential three sides of the direct cooling water cooler 29 are bent downwardly with the flange 30 facing the rear, and the rearwardly facing flange 31 is formed with the frontward bending. The flange 30 is provided with three engaging protruding horseshoe 32 protruding forwards corresponding to the communication hole 26 mentioned above.

Then, the direct cooling cooler 28 inserts the engaging protruding horseshoe 32 into the communication hole 26 of the flange fitting groove 25 from the upper side, and then attaches the engaging protruding horseshoe 32 to the supporting point ( It is installed in the jaw 23 and the protrusion part 24 by engaging the claw 27 which engages the flange 31 by rotating it to the rear lower side by using a, 点, and the flange 30 is a groove which a flange fits It is to be inserted into 25 and fitted.

As a result, a space 33 for storing the refrigerant pipe 29 is formed between the lower surface of the direct cooling cooler 28 and the upper surface of the upper cover 9, which is the bottom surface of the freezing chamber 6.

In addition, "34" is a sealing member attached to four peripheral sides of the lower surface of the above-mentioned direct cooling cooler 28 by adhesion or the like, which is in contact with the upper surface of the above-described protrusion 24 and the jaw 23 by pushing.

Next, the operation of the present embodiment will be described.

When the refrigeration cycle and the driving motor 18 is operated, the refrigerant is supplied to the refrigerant pipe 29 of the intercooling cooler 16 and the direct cooling cooler 28, and the cold air from the intercooling cooler 16 By the blowing action of (19), it is sent from the cooler duct 15 into the cold air passage 22, and is discharged from the discharge port 21 into the freezer compartment 6 to cool the inside of the freezer compartment 6, and then to the inlet 11 and It is circulated by returning from the cooler duct 15 to the bottom of the intercooled cooler 16 via the ventilation path 12.

Then, when the ice tray (not shown) is placed on the direct cooling cooler 28, the direct cooling cooler 28 makes the deicing quickly.

In this case, when the ice making plate is placed on the direct cooling cooler 28, if the water in the ice making tray flows onto the direct cooling cooler 28, the water flows into the flange fitting groove 25 and then the communication hole 26. From the ventilation path 12 to be stored in the water receiving place 13, the water stored in the water receiving 13 is discharged to the outside through a drain pipe (not shown).

In addition, a part of the cold air sent to the cold air passage 22 is supplied to the refrigerator compartment 7 through a cold air duct (not shown), and the cold air in the refrigerator compartment 7 is separated from the ventilation passage 12 in the partition wall 5. It is returned to the lower side of the intercooled cooler 16 in the cooler duct 15 through the formed ventilation path (not shown).

Thus, according to the present embodiment, the direct cooling cooler 28 is installed to be mounted on the jaw 23 and the protrusion 24 of the upper cover 9 on the partition wall 5 through the sealing member 34. Since the flange 30 is inserted into the fitting groove 25 around the protruding portion 24 so that the water flows on the direct cooling cooler 28, the water is retained by the flange fitting groove 25 and the flange. Since the water flows into the ventilation path 12 through the communication hole 26 that is also used as the engaging hole of the fitting groove 25, the space between the lower surface of the direct cooling cooler 28 and the upper surface of the upper cover 9 ( Since it is possible to reliably prevent freezing by invading into 33), it is possible to prevent the direct cooling cooler 28 from being deformed or separated by freezing.

For this reason, according to this embodiment, even if the direct cooling cooler 28 is enlarged in the upper part of the partition wall 5 which is the lowest in the freezer compartment 6, there is no problem.

In addition, in the above-described embodiment, the freezer compartment 6 and the lower refrigerating compartment 7 of the refrigerator body 1 are partitioned by the partition wall 5 in the refrigerator body 1, but instead of the refrigerating chamber 7, the freezer compartment is used for another storage compartment. It is good also as a specification switching room which can be converted into an overcooling chamber.

In addition, the present invention is not limited to the embodiment described above and shown in the drawings, for example, the sealing member 34 of the lower surface of the direct cooling cooler 28 may be provided as necessary, and it is suitable within the scope not departing from the gist. Of course, it can be modified and implemented.

As described so far, even if the direct cooling cooler is installed on the top of the partition wall, which is the bottom of the cooling chamber, the present invention can reliably prevent water from invading into the space formed by the lower surface of the direct cooling cooler and the upper surface of the partition wall. It is said to have an excellent effect.
