The invention of claim 5 is characterized in that, in the invention of claim 4, the discharge opening is formed in the left and right side walls of the evaporating dish.

<Invention of Claim 1>
By driving the blower fan, outside air is sucked into the casing from the lower surface by the suction port, and then blown out from the side surface by the blower outlet. Since the air blower is provided on the bottom surface of the storage body, an air flow along the bottom surface of the body can be obtained without causing the bulkiness of the cooling storage.
Dust and dust are likely to accumulate on the floor at the location where the cooling storage is installed, and there is a risk that it will rise when the outside air is sucked in. Dust and dust are captured and prevented from entering the blower fan. Usually, a space is secured in front of the air outlet, but the filter can be easily attached and detached using the space from the side surface provided with the air outlet, which is convenient for cleaning the filter.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
<Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. In this embodiment, the case where it applies to a commercial refrigerator is illustrated.
In FIG. 1, the code | symbol 10 is a refrigerator main body, Comprising: It forms with the heat insulation box opened to the front surface, and the inside becomes the refrigerator compartment 11, The door opening type heat insulation door 12 is in the front opening of the refrigerator compartment 11. It is installed in two separate upper and lower stages.

Legs 15 are attached to the four corners of the bottom surface 14 of the refrigerator main body 10, and the bottom surface 14 is supported in a state where it floats from the floor surface X by a predetermined dimension. As shown in FIG. 2, the leg 15 has a screw rod 16 projecting from the upper surface thereof, and screw holes 17 are formed at the four corners of the bottom surface 14 by attaching nuts (not shown) on the back side. The screw rod 16 is detachably mounted by screwing it into the screw hole 17.
A machine room 13 is provided on the upper surface of the refrigerator main body 10 and is equipped with a refrigeration apparatus, an electrical box, etc. (not shown), and the cold air generated by the refrigeration apparatus is circulated and supplied into the refrigeration room 11 so that the refrigeration room. 11 is cooled and held, and a stored item is put in and out of the refrigerator compartment 11 while opening and closing the heat insulating door 12.

A blower 20 is attached to the bottom surface 14 of the refrigerator body 10. The blower 20 generally has a structure in which a cross flow fan 21 is accommodated in a casing 30.
The casing 30 is made of a metal plate, and as shown in FIGS. 2 and 3, the casing 30 has an elongated shape having a length comparable to the depth dimension of the refrigerator body 10 and is formed in a box shape with an open top surface. Yes. At the upper edges of both end surfaces of the casing 30 in the length direction, mounting plates 31 bent at right angles to the outside are formed, and the screw rods 16 of the above-described legs 15 can be inserted in the mounting plates 31 in the radial direction. A mounting groove 32 is formed by cutting from the rear edge side.

  As shown in FIGS. 3 and 5, a mounting base 34 that rises one step is attached to the bottom surface of the casing 30 in the region of a little over half on the right side of FIG. 3. The cross flow fan 21 is provided in a substantially central region that is divided into three in the length direction when viewed from a slightly more than half region of the casing 30 as a whole. The cross flow fan 21 includes a fan main body 22 having an elongated shape in the axial direction with a plurality of blades provided on the outer peripheral surface, and both end portions of the fan main body 22 can freely rotate on a support plate 23 that stands on a mounting base 34. It is supported and connected to a motor 24 provided on one support plate 23. A cover 25 is provided from the rear surface (upper side in FIG. 3) to the upper surface of the fan main body 22. Thereby, the cross flow fan 21 can blow out the air sucked from below, for example, as a uniform plane flow toward the front perpendicular to the cross flow fan 21.

Window holes 35 and 36 are opened below the position where the cross flow fan 21 is disposed on the mounting base 34 and below the position where the motor 24 is disposed. Further, the lead wire 24 </ b> A of the motor 24 is drawn out through the rear plate of the casing 30.
As shown in FIG. 2, four suction ports 37 shown in the figure are opened side by side on the lower surface of the casing 30 over a slightly half region on the right side of the figure. On the other hand, on the front surface of the casing 30, a plurality of small air outlets 38 are formed side by side in a region corresponding to the entire length of the cross flow fan 21 at the upper edge thereof.

Here, an air filter 40 that can be mounted over the region where the suction port 37 is formed is provided. As shown in FIG. 2, the air filter 40 has a structure in which a stainless steel metal mesh 42 is stretched in a frame 41 made of a metal plate such as a stainless steel plate. In addition, a handle 43 having a bowl-shaped cross section that is bent at a right angle forward after standing up is formed on the front edge of the frame body 41 over the entire width.
On the other hand, an insertion groove 45 into which the air filter 40 can be inserted and removed is formed at the lower edge of the front surface of the casing 30 over the region where the suction port 37 is formed. Therefore, when the air filter 40 is inserted into the insertion groove 45 until the handle 43 hits the front surface of the casing 30, the air filter 40 can cover the upper surfaces of all the suction ports 37.

  Then, the effect | action of this embodiment is demonstrated. First, the air blower 20 is attached along the right side edge seen from the front in the bottom face 14 of the refrigerator main body 10. For this purpose, the screw rods 16 of the legs 15 provided at the front and rear of the right side of the bottom surface 14 are loosened. When the leg 15 is loosened, the blower 20 is applied to the bottom surface 14 of the refrigerator body 10 with the air outlet 38 facing left, and the mounting rod 32 of the mounting plate 31 faces the gap with the bottom surface 14. 16 is slid to the right while being inserted in the radial direction. When both the screw rods 16 are slid until they hit the inner ends of the corresponding mounting grooves 32, when both the legs 15 are tightened again, the both mounting plates 31 are clamped, so that the casing 30, that is, the blower 20 is combined with the legs 15. Fixed. At the same time, the air filter 40 is inserted into the insertion groove 45 of the casing 30.

Thereby, as shown in FIG. 6, the blower 20 is mounted along the right edge of the bottom surface 14 of the refrigerator body 10. Note that the lead wire 24 </ b> A drawn out from the motor 24 rises and is wired along, for example, the back surface or side surface of the refrigerator main body 10, and is connected to a power feeding unit in an electrical box provided in the machine room 13.
During operation of the refrigerator, the motor 24 of the cross flow fan 21 is always energized and driven. When the cross flow fan 21 is driven, as shown by the arrow in FIG. 6, outside air is sucked from the suction port 37 on the lower surface of the casing 30 and introduced into the casing 30, and passes through the window hole 35 of the mounting base 34. After that, the direction is changed to the left side of the figure by the fan main body 22, and the air is blown out from the air outlet 38. Subsequently, it circulates along the bottom surface 14 of the refrigerator body 10 toward the left edge.
Since the bottom surface 14 of the refrigerator main body 10 is cooled by the cold air in the refrigerator compartment 11, there is a possibility that condensation occurs due to the contacted outside air. However, as described above, when air flows along the bottom surface 14, Compared to air, the humidity is kept low, and condensation is less likely to occur.

  It should be noted that dust or dust tends to accumulate on the floor surface X at the position where the refrigerator is installed, and there is a risk that it will rise and be sucked together when outside air is sucked. However, the suction region is limited to the suction port 37, and the air filter 40 is attached to the suction port 37, so that dust and dust are prevented from being captured by the air filter 40 and entering the cross flow fan 21. . Moreover, although a part of the sucked outside air is used for cooling the motor 24, the cooling air is also passed through the air filter 40, so that dust and dust similarly enter the motor 24. This is avoided.

On the other hand, the air filter 40 needs to be appropriately cleaned. In that case, a hand is put in the bottom face 14 of the refrigerator main body 10, the handle 43 is grasped, and the air filter 40 is pulled out from the casing 30 toward the left side as shown by a chain line in FIG. After washing with water and the like, contrary to the above, the air filter 40 is inserted into the bottom surface 14 side of the refrigerator main body 10 from the front, and is inserted from the insertion groove 45 of the casing 30 and attached.
In this case, the left side of the air blower 20 has a large space enough to correspond to almost the entire area of the bottom surface 14 of the refrigerator body 10, and the insertion groove 45 of the air filter 40 is also as far as possible in the casing 30. Since it is formed, the air filter 40 can be easily inserted and removed easily and efficiently.

  As described above, according to the present embodiment, when the cross flow fan 21 mounted on the blower 20 is driven, outside air is sucked into the casing 30 from the lower suction port 37 and then from the side blower outlet 38. By blowing out and flowing along the bottom surface 14 of the refrigerator main body 10 and reducing the humidity of the air that contacts the bottom surface 14, dew condensation is prevented. Since the air blower 20 is provided on the bottom surface 14 of the refrigerator main body 10, an air flow along the main body bottom surface 14 can be obtained without causing the bulkiness of the cooling storage.

On the other hand, the floor X at the refrigerator installation position tends to accumulate dust and dust, and it may rise up when the outside air is sucked in. However, the suction area is limited to the suction port 37 and the air filter 40 is provided. Therefore, dust and dust are prevented from being trapped and entering the cross flow fan 21.
The air filter 40 needs to be cleaned with water or the like as appropriate, and needs to be removed from and inserted into the casing 30 each time. On the left side of the casing 30 that is the direction in which the air filter 40 is drawn, the bottom surface 14 of the refrigerator body 10 is provided. Since a large space corresponding to almost the entire area is secured, and the insertion groove 45 of the air filter 40 is also formed on the relatively front side of the casing 30, the insertion / extraction operation of the air filter 40 is easily and efficiently performed. be able to.

Further, the front plate 73 of the suction duct 70 is positioned so as to be retracted from the front surface of the storage case 55 to a depth of a predetermined dimension.

A suction port 75 is formed in the front side region of the bottom plate of the suction duct 70 by forming a plurality of slits facing in the front-rear direction so as to be arranged substantially over the entire width.
Here, an air filter 80 that can be mounted over the region where the suction port 75 is formed is provided. The air filter 80 has a structure in which a stainless steel metal mesh 82 is stretched in a frame 81 made of a metal plate such as a stainless steel plate. In addition, a handle 83 having a cross-sectional gate shape that is bent at a right angle twice forward and downward after standing up is formed on the front edge of the frame body 81 over the entire width.
On the other hand, an insertion groove 85 into which the air filter 80 can be inserted and removed is formed at the lower edge of the front plate 73 of the suction duct 70. Therefore, when the air filter 80 is inserted into the insertion groove 85 until the handle 83 hits the front plate 73 of the suction duct 70, the air filter 80 can cover the upper surface of the suction port 75. At this time, the handle 83 is substantially flush with the front surface of the storage case 55.

The evaporation unit 50 is assembled as described above, and the front surface of the storage case 55 is applied to the front surface of the refrigerator body 10 at the center in the width direction of the bottom surface 14 of the refrigerator body 10, and the mounting plate 58 of the storage case 55 is attached.
