Description

[0001]
[Industrial applications]
According to the present invention, it is possible to efficiently cool the condenser and the compressor by eliminating the intake of exhaust air from the refrigerator. The present invention also relates to a refrigerator that can be easily transported.
[0002]
[Prior art]
An example of a conventional refrigerator is shown in Japanese Utility Model Laid-Open No. 6-3032, which will be described with reference to FIGS.
[0003]
1 is a refrigerator main body, 2 is a machine room, 3 is an outer box bottom plate, 4 is a heat radiating pipe, and 5 is a full width plate of the refrigerator in which the heat radiating pipe is adhered to the lower side.
[0004]
6 is a compressor, 7 is a blower, 8 is a fan of the blower 7, 9 is a partition plate for dividing the machine room 2 into two right and left, 10 is the compressor 6 and the blower 7 disposed behind the plate 5. A mounting plate 5a is an air inlet provided on the plate 5 at a position where the heat radiating pipe 4 escapes, 11 is an evaporating dish, 12 is a machine room cover, and 12a is an air outlet provided on the machine room cover 12. It is. The arrows in the figure indicate the direction of air convection.
[0005]
The operation of the refrigerator configured as described above will be described.
The air taken in by the blower 7 from the air suction port 5a of the plate 5 at the position where the heat radiating pipe 4 has escaped passes through the heat radiating pipe 4 and the plate 5, convects with the blower 7 and the compressor 6, and flows into the machine room cover 12. The air is blown to the provided air outlet 12a.
[0006]
[Problems to be solved by the invention]
However, in the above configuration, the air taken in by the blower 7 passes through the plate 5 in which the radiating pipe 4 is adhered to the lower side, so that the suction air temperature is high. There was a possibility that cooling could not be performed efficiently and the cooling performance was inferior.
[0007]
In addition, as shown by arrows in FIGS. 11 and 14, high-temperature convection air is not completely discharged from the air discharge port 12a provided in the machine room cover 12, and a plate 5 having a radiation pipe 4 partially forward. The circuit is short-circuited, and the high-temperature air flowing through the air suction port 5a provided in the plate 5 again to the compressor 6 in the machine room 2 flows to the compressor 6, so that the performance due to the decrease in the cooling efficiency of the compressor is reduced. The structure was such that the wind path caused deterioration, and the noise of the compressor was transmitted directly to the front of the refrigerator.
[0008]
Further, since the plate 5 having the heat radiating pipes 4 is installed so as to have a large overall width in front of the refrigerator main body 1, a transport handle cannot be easily provided freely, and the refrigerator has poor transportability.
[0009]
Even if the present invention is used in a high-temperature environment or for long-term use, or when a refrigerator is installed in a system kitchen, the intake air is always fresh air (fresh low-temperature air) and the intake air (high temperature) is always taken in. There is no effective cooling of the condenser and compressor, no deterioration in performance, low noise, and the ability to transport the refrigerator vertically and horizontally, making it easy to transport on stairs and narrow places. The purpose is to make it inexpensive.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, in the refrigerator of the present invention, a fitting is provided by a duct cover provided with an air suction port on a bottom surface made of a synthetic resin and installed on the entire width of the lower portion of the refrigerator, and an engaging piece extending from the duct cover. A full width shielding plate that divides the depth direction of the refrigerator into two parts between the bottom surface of the duct cover and the floor surface, a mounting plate provided behind it, and a machine room installed on the mounting plate And a machine room cover with an air exhaust port. The blower passes fresh air through the duct cover directly to the condenser and compressor. It is guided and discharged from the air exhaust port of the machine room cover.
[0011]
The duct cover has a pair of recesses (handles) in a part thereof and a through hole in a part of the mounting plate.
[0012]
[Action]
The present invention has the above-described structure, in which the closing plate provided below the duct cover does not take in the exhaust air, and only the fresh air from the front of the refrigerator is taken in using the full width of the duct cover, so that the compressor is used. The cooling effect of the condenser is enhanced.
[0013]
Further, in the refrigerator carrying handle, a pair of recesses are provided in the width direction using a duct cover, and a through hole of the mounting plate is provided in the depth direction, so that the refrigerator can be transported in the vertical and horizontal directions. Can be achieved.
[0014]
【Example】
Hereinafter, a refrigerator according to an embodiment of the present invention will be described with reference to FIGS.

[0016]
16b is an engagement piece extending from the duct cover 16 fitted with the shielding plate 17, 18 is a compressor, 19 is a condenser, 20 is a blower, 21 is a fan of the blower 20, and 22 is a machine room. A partition plate 23 that is divided into two parts, left and right, denotes a mounting plate on which the compressor 18, the condenser 19, and the blower 20 are disposed behind the duct cover 16.
[0017]
A pair of recesses 16c are formed in a part of the bottom surface of the duct cover 16. Further, a through hole 23a is formed in the mounting plate 23 described above. 24 is a machine room cover, and 24a is an air discharge port provided in the machine room cover 24.
[0018]
Arrows in the figure indicate the direction of air convection.
The operation of the refrigerator configured as described above will be described.
[0019]
The air taken in by the blower 20 from the air inlet 16a of the duct cover 16 passes between the refrigerator outer case bottom plate 15 and the duct cover 16 and convects with the blower 20, the condenser 19, and the compressor 18, and the machine room cover 24 The air is blown to the air discharge port 24a provided in the air conditioner.
[0020]
In addition, a pair of recesses 16c and a through hole 23a provided in a part of the mounting plate 23 disposed behind the duct cover 16 are formed by using a part of the front of the duct cover 16 made of a synthetic resin. As a result, when the refrigerator is carried by two persons, first, as shown in FIG. 6, one person holds a handle (not shown) on the upper rear surface of the refrigerator main body 13 as shown in FIG.
