In the second embodiment, the cooling air circulation fan 14 is inclined in accordance with the inclination of the cooler 12 as compared with the first embodiment, and a partition plate on the front surface of the cooling air circulation fan 14 is provided. 17 and the mouth ring plate 18 are also different in that they are similarly inclined. Thereby, the internal volume of the freezing room 3 can be further increased. At this time,
The discharge port of the partition plate 17 also serving as a fan guard may be directed to the storage container 3a installed in the freezing compartment 3. In addition, the shape of the back surface of the storage container 3a installed in the freezing room 3 is also inclined according to the inclination of the partition plate 17, so that the actual storage amount of the storage container 3a of the freezing room 3 can be increased. is there.

Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 4 is a sectional view of a main part of a refrigerator according to a third embodiment of the present invention.

In the third embodiment, as compared with the first embodiment, the mounting position of the defrosting tube heater 13 is set to a half of the depth dimension D1 of the lower end surface of the cooler 12. 1, that is, the relationship between the distances D2 and D1 between the rear side of the lower end surface of the cooler 12 and the defrosting tube heater 13 is D1 / 2.
The defrosting tube heater 13 is arranged so that> D2. Thereby, when the cooler 12 is inclined, it is possible to prevent the heat of the defrosting tube heater 13 from becoming difficult to reach to the upper part (particularly, the rear side) of the cooler 12, and it is possible to efficiently defrost the cooler 12. Therefore, the defrosting time can be shortened, which can lead to power saving.

In the embodiment of the present invention described above,
The machine room 19 is formed lower than the freezing room 3, and the cooler 12 is arranged to be inclined above the compressor 20 and the cooler room 1 is formed.
6 is inclined at least at a portion along the cooler 12, so that the ineffective space above the compressor 20 can be used for the cooler room 16 in which the cooler 12 is arranged.
Can be increased, and the height of the freezing compartment 3 can be reduced by an amount corresponding to the inclination of the cooler 12. If the height of the freezing compartment 3 is reduced, the ineffective space above the compressor 20 can be reduced.

Further, the cooler 12 is formed in a thin and substantially rectangular shape having a cooler pipe 12a and a cooler fin 12b, and the cooler 12 is arranged at an angle above the compressor 20 to be inclined. Since at least the portion of the chamber 16 where the cooler 12 is disposed is inclined, and a suction port 17a communicating with the freezing chamber 3 is formed below the cooler chamber 16, the suction port 17a of the cooler chamber 16 is Cooler 1 at top end height
2, the suction area can be increased by increasing the front end of the lower surface of the lower part 2 by the upper part, and the ventilation resistance of the suction port 17a can be reduced to improve the performance.

Further, a cooling air circulating fan 14 having a fan motor 14b and a fan blade 14a mounted in front of the fan motor 14b is disposed above the cooler room 16, and is sucked in from the back side of the fan blade 14a and blows out forward. Since the cool air is provided to the freezer compartment 3 and the storage compartments 4 and 5 afterwards, the inactive space above the compressor 20 can be used for the cool air circulation fan 14, thereby providing the freezer compartment 3 and the storage compartment 4. 5, a space for distributing the cool air to the refrigerator compartment 5, and the performance can be improved while increasing the internal volume of the freezing compartment 3.

Further, since the mounting direction of the cooling air circulating fan 14 is inclined so as to match the inclination direction of the cooler 12, the cooling air circulating fan 14 is located further rearward and is located above the compressor 20. The ineffective space can be used, whereby the internal volume of the freezing room 3 can be further increased, and the height of the freezing room 3 is reduced by the inclination of both the cooler 12 and the cool air circulation fan 14. can do.

Further, since the position in the depth direction of the defrosting tube heater 13 disposed immediately below the cooler 12 is located on the back side of a position which is a half of the depth dimension of the lower surface of the cooler 12, it is possible to remove the heater. Cooler 12 in which the heat of frost tube heater 13 is inclined
, And can efficiently defrost the cooler 12, thereby shortening the defrosting time and saving power.

[0029]

According to the present invention, the ineffective space above the compressor can be used for the cooler room in which the cooler is arranged, whereby the internal volume of the freezer can be increased and the cooler can be tilted. It is possible to obtain a refrigerator that can reduce the height of the freezer by the amount
