2. Description of the Related Art Refrigerators and the like configured to cool a storage space to a predetermined temperature by a refrigeration mechanism or the like disposed inside a housing are suitably used in kitchen facilities such as coffee shops and restaurants. FIGS. 10 to 12 show a refrigerator of an upper type in which a refrigeration mechanism is provided at an upper portion of a main body,
The refrigerator 10 has an upper part of a main body 12 for storing foods and the like,
Front panel 14 and left and right side panels 16,1
6 defines a machine room 18 whose top and back are open, and a refrigeration mechanism 2 for cooling the inside of the refrigerator in the machine room 18.
0, the electrical box 22, the control box 24, etc., are arranged.
Connected by

The refrigeration mechanism 20 includes an air-cooled condenser 2
8, basically comprises a condenser fan 30, a compressor 32, a cooler 34, etc., and the condenser 28 is arranged at a position separated from the back surface (the machine room side surface) of the front panel 14 and The filter 36 is arranged on the front side. By operating the condenser fan 30, air around the condenser 28 is sucked into the condenser 28 through the filter 36, and the high-temperature refrigerant supplied from the compressor 32 to the condenser 28 is When passing through the condenser, heat is exchanged with the air to be cooled.
The air that has cooled the condenser 28 is blown to the compressor 32 to cool it, and then blown to the rear side of the machine room 18.

[0004]

Depending on the installation location where the refrigerator 10 is used, the surrounding environment, and the like, oil and the like may adhere to the air filter 36. That is,
In a kitchen using oil or the like, a large amount of evaporated oil floats in the air.
The filter 36 collects oil in addition to dust contained in the air. If a large amount of oil adheres to the filter 36 during a certain period of use, a part of the oil will flow down the filter 36 and contaminate the floor of the machine room 18.

[0005] Further, since the air suction portion (front side) of the condenser 28 is not enclosed, when the condenser fan 30 is operated, the electric box 22 installed around the condenser 28 is turned off. Then, air passes through gaps between the control box 24 and the wiring member 26 and is sucked into the condenser 28. For this reason, it is pointed out that oil and dust adhere to the electrical box 22, the control box 24, the wiring member 26, and the like and become dirty. Further, the condenser 28
The air after the heat exchange blown out to the compressor 32 side on the rear side goes around the front side of the condenser 28 again and is sucked.
There is a problem that a so-called short cycle is caused and the refrigeration capacity is reduced. In addition, when the back surface of the refrigerator 10 is installed so as to be in contact with a wall or the like, the short cycle is more likely to occur because the air after heat exchange bounces off the wall or the like.

A drain receiver 70 is provided below the condenser 28 so that oil and dew falling from the condenser 28 flow through the drain receiver 70 onto the bottom plate of the duct 58. The bottom of the duct 58 is formed in a dish shape in which the front edge and the rear edge of the duct 58 rise at a predetermined height over the entire width of the opening, and the oil, dew, and the like flowing from the drain receiver 70 accumulate. ing.

[0016]

Next, the operation of the intake structure of the machine room according to the above-described embodiment will be described. The condenser fan 30
Is started, the external air on the front side of the front panel 14 is sucked into the duct 58 through the louver 48. At this time, since the louver 48 and the duct 58 are kept airtight by the packing 60, no external air is sucked into the machine room from between them. When all the external air sucked into the duct 58 passes through the filter 62, dust, oil, and the like mixed in the air are collected, and the purified air is transferred to the condenser 28. It is sucked and air cooled. Further, the air blown to the back side of the condenser 28 is further air-cooled to the compressor 32 and then discharged outside from the back side of the machine room 18.

As described above, the external air for cooling the condenser 28 sucked through the louver 48 is all guided to the air suction portion of the condenser 28 through the duct 58.
Contamination due to oil and dust contained in the air is limited only to the inside of the duct through which the air flows. That is, the electrical box 22, the control box 24, the wiring member 26, and the like disposed around the condenser 28 can be prevented from being contaminated with oil, dust, and the like. Further, the duct 58 prevents the air after the heat exchange blown out to the rear side of the condenser 28 from flowing back into the air suction portion of the condenser 28 again, thereby preventing a decrease in the refrigerating capacity due to the short cycle. it can. Furthermore, even when the rear surface of the refrigerator 10 is installed so as to be in contact with a wall or the like, the air after the heat exchange does not cause a short cycle, and
Is discharged outside through the

The oil and the like adhere to and accumulate on the filter 62 with time, and the oil and the like flow down along the surface of the filter 62 and are collected by a collecting hole 64 a formed in the bottom plate 64 of the duct 58.
Through the oil pan 68. Also, since the rear portion of the louver 48 protrudes into the machine room,
The oil and the like adhering to the slats 52 and the like of the louver 48 flow to the rear side and fall into the duct 58, which also collects the recovery holes 64.
The oil is collected by the oil pan 68 via the line a. In addition, fine oil and the like are not collected by the filter 62,
Although it may adhere to the condenser 28, even if the oil and the like and dew and the like generated in the condenser 28 flow down, they all flow into the duct 58 through the drain receiver 70. That is, the bottom surface of the machine room 18 is reliably prevented from being contaminated by the oil flowing down from the filter 62, the louver 48, the condenser 28 and the like.

A filter 6 is provided inside the duct 58.
Since 2 is disposed in the inclined posture, the surface area of the filter 62 for collecting dust of the filter 62 can be made sufficiently larger than the surface area of the air suction section in the condenser 28. Therefore, the period until the filter 62 is clogged can be lengthened, and the interval for performing maintenance such as cleaning can be lengthened to reduce maintenance costs.

Next, when cleaning or replacing the filter 62 during regular maintenance or the like, the front panel 14 is pulled up to open the front opening of the machine room 18 and disposed inside the duct 58. The extracted filter 62 is taken out. After the cleaned filter 62 or another new filter 62 is disposed inside the duct 58, the front panel 14 closes the front opening of the machine room 18 to complete the operation. In addition, by opening the front opening, the front side of the support member 66 is also opened, so that the oil pan 68 can be taken out of the support member 66 to easily discard or wash oil and the like.

It is configured as follows.

[0028]

Next, the operation of the air intake structure of the machine room according to the above-described another embodiment will be described. When the operation of the condenser fan 30 is started, external air on the front side of the front panel 14 is sucked into the duct 78 via the louver 48. At this time, since the louver 48 and the duct 78 are hermetically sealed by the packing 60, no outside air is sucked into the machine room from between them.
When all the external air sucked into the duct 78 passes through the filter 82, dust, oil, and the like mixed in the air are collected, and the purified air is removed from the condenser 2.
It is sucked into 8 and cooled by air. Further, the air blown to the rear side of the condenser 28 is further air-cooled to the compressor 32 and then discharged outside from the rear side of the machine room 18.

At this time, it is prevented by the duct 78 that the heat-exchanged air blown out to the rear side of the condenser 28 flows back to the air suction portion of the condenser 28 again, and the refrigeration capacity due to the short cycle is reduced. Drop can be prevented.
Furthermore, even when the back surface of the refrigerator is installed so as to be in contact with a wall or the like, the air after heat exchange is discharged outside through the exhaust hole 42a of the top panel 42 without a short cycle.

As described above, all the external air for cooling the condenser 28 sucked through the louver 48 is guided to the air suction portion of the condenser 28 through the duct 78, and thus is included in the air. Dirt due to oil and dust is limited only to the inside of the duct 78 through which the air flows. That is, the electrical box 22, the control box 24, the wiring member 26, and the like disposed around the condenser 28 can be prevented from being contaminated with oil, dust, and the like. Further, by disposing the filter 82 near the suction port of the duct 78 (on the lower portion 80 side), oil in the air entering the duct 78 can be collected near the suction port. It is possible to reduce the adhesion of dirt on the entire inside.

Then, oil and the like adhere and accumulate on the filter 82 with time, and the oil and the like flow down along the surface of the filter 82, and are collected in a lower portion 80 of the bottom plate 78a of the duct 78. Oil pan 68 through 80a
Can be recovered. Further, since the rear surface of the louver 48 projects into the machine room 18, oil and the like adhering to the slats 52 and the like of the louver 48 flow to the rear surface and flow through the duct 78.
Into the oil pan 6 through the collecting hole 80a.
8 can be collected. The oil and the like collected in the oil pan 68 also opens the front side of the support member 66 by opening the front opening of the front panel 14, so that the oil pan 68 is taken out from the support member 66 to the outside. , Oil and the like can be easily discarded and washed.

Further, since the duct 78 is detachably provided, when the inside of the duct 78 is very dirty, the duct 78 can be removed and cleaned, and the cleaning work of the duct 78 and the maintenance work of the refrigerating apparatus 20 can be performed. Can be easily performed. At this time, as shown in FIG. 9, the projecting portion 78b of the duct 78 has a housing space 7 formed below the condenser 28.
Since it is configured to be housed in the duct 4a, the work of attaching and detaching the duct 78 can be easily performed. Since the filter 82 set in the duct 78 is detachable, the filter 82 can be cleaned at normal times, and the cleaning work and maintenance are not complicated.

As shown in FIG. 7 or FIG. 8, a projecting portion 78b of the duct 78 is provided below the condenser 28.
Is extended, and the condenser 28 is configured to face above the protruding portion 78b through the cutout portion 74c of the gantry 74, and fine oil and the like are collected by the filter 82. Even if the oil and the like and the dew and the like generated in the condenser 28 flow down and adhere to the condenser 28, the oil and the like fall down to the projecting portion 78b and are collected by the oil pan 68, The bottom of the machine room 18 does not get dirty. The duct 78 is provided below the condenser 28.
Of the condenser 28 is extended.
When the dirt becomes severe, it is possible to collect the water or the like that has washed the condenser 28 through the duct 78 without polluting the bottom surface of the machine room 18.

As shown in FIG. 6, the bottom plate 78a of the duct 78 is formed in a stepped shape comprising an upper portion 79 on the back side and a lower portion 80 located on the front side with respect to the upper portion 79. Thus, the oil and the like flowing down to the upper section 79 can naturally flow down to the lower section 80 side, and can be recovered to the oil pan 68 from the recovery hole 80a formed in the lower section 80. For this reason, it is possible to suppress the accumulation of oil and the like in the duct 78, to reduce the generation of dirt in the duct 78, and to reduce the burden on the cleaning work of the duct 78 and the maintenance work of the refrigerating device 20. obtain. Here, if the upper section 79 is inclined downward toward the lower section 80, oil and the like can be moved to the lower section 80 more efficiently. In addition, a rising surface is formed in the upper part 79 and the lower part 80 of the bottom plate 78a in the duct 78, and the bottom plate 78a
Since the entirety of “a” is formed in a dish shape, it is possible to prevent oil and the like flowing down into the duct 78 from spilling on the bottom surface of the machine chamber 18 and becoming dirty.

The recovery hole formed in the duct may be a single hole instead of a plurality of holes. Further, the device adopting the air intake structure of the machine room is not limited to a refrigerator or a freezer, but a device adopting an air-cooled condenser such as an ice machine, a showcase, or an air conditioner. Should be fine. Further, in the embodiment, the type in which the machine room is defined in the upper portion of the main body has been described, but the present invention can be applied to an apparatus in which the machine room is defined in the lower portion of the main body.

The shape of the mount on which the condenser is mounted is not limited to that of the embodiment, and the storage space in the mount is opened upward, and the oil and the like adhering to the condenser are located below the condenser. Any type of gantry can be adopted as long as it flows down to the protruding portion of the duct that extends. Although a louver is formed as a suction portion provided on the front panel, a plurality of slit-shaped through holes may be simply formed.

[0037]

As described above, in the intake structure of the machine room according to the present invention, oil and the like adhering to the filter and flowing down can be collected in the oil pan through the collection hole provided in the duct. In addition, the bottom surface of the machine room can be prevented from being stained with oil or the like.

Further, since the bottom plate of the duct is formed in a dish shape, it is possible to reliably prevent oil or the like flowing down on the bottom plate from spilling to the bottom of the machine room. Further, the bottom plate of the duct is
By forming a stepped shape consisting of an upper portion on the back side and a lower portion provided on the front side and located below the upper portion, and providing a filter and a recovery hole in the lower portion, the oil content in the air can be reduced. Can be collected and discharged immediately after entering the duct, so that the generation of dirt in the duct can be reduced, and the burden on cleaning work and maintenance work can be reduced.

By configuring the bottom plate of the duct so as to extend below the condenser, oil and the like flowing down from the condenser fall on the bottom plate, so that the bottom of the machine room is not stained. Further, even if the condenser is directly washed when it becomes dirty,
The falling dirt can be received by the bottom plate of the duct and does not stain the machine room.
