DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower for a refrigerating mechanism, and more particularly to a refrigerator having a storage room for refrigerated storage of foods, beverages, etc., for cooling the storage room. The present invention relates to a blower for supplying cooling air to a condenser constituting the refrigeration apparatus.

[0002]

2. Description of the Related Art In a showcase or a refrigerator for refrigerated storage of refrigerated articles such as foods and beverages, a storage room is provided inside a heat insulating box in which a heat insulating material is provided between an interior plate and an exterior plate. A refrigerator body is provided, for example, at a lower portion of the heat insulation box, and a machine body defining a machine room for accommodating a compressor, a condenser, an electrical board, and the like in the refrigeration mechanism is provided. Then, a cooler installed at a predetermined position in the storage room is cooled under the refrigeration operation of the refrigeration mechanism, and air in the storage room is circulated while being in contact with the cooler, so that the storage room has a set temperature. To be cooled.

In the refrigerating mechanism, in a refrigerating operation, a refrigerant in a gas state of high temperature and high pressure which is compressed by the compressor changes state to a high pressure liquid refrigerant while releasing heat in the condenser. Therefore, for example, air is supplied to the condenser by a blower (fan) installed in the vicinity of the condenser, and heat exchange is performed between the air and the condenser to cool the condenser. . Air that has been appropriately heated by heat exchange with the condenser is blown onto an evaporating dish installed at the lower part of the body, such as defrost water or dew water stored in a storage section of the evaporating dish. The wastewater is evaporated or blown toward the compressor to cool the compressor.

[0004]

In the conventional blower, however, the condenser is basically provided with only one fan composed of a motor and a fan blade mounted on the rotating shaft of the motor. Was. For this reason,
In order to cool the condenser efficiently with one unit, it is necessary to increase the size of the fan. Therefore, a large fan blade capable of supplying a large amount of air, and a large fan blade for continuously rotating the fan blade are required. In addition, a high-output motor is required.
Therefore, the fan blade must be made of aluminum or the like in order to reduce the weight and increase the rigidity, and there is a disadvantage that the manufacturing cost increases. On the other hand, in the motor, an expensive motor such as a condenser motor has to be adopted, and the cost increase due to this has been a problem that cannot be ignored. Further, even if the condenser can be suitably cooled by adopting a large fan, since the air blowing direction and the blowing range are limited to the front side of the air blowing side of the fan, both the evaporating dish and the compressor are used. Thus, there is a problem that the air cannot be efficiently blown, and neither the evaporation of the waste water in the evaporating dish nor the cooling of the compressor can be efficiently performed. Furthermore, because there is only one motor,
If the motor fails, the condenser is not cooled,
It is pointed out that the refrigeration operation of the refrigeration mechanism stops, and the cooling of the storage chamber stops completely.

[0005]

SUMMARY OF THE INVENTION The present invention has been proposed to solve the above-mentioned problem suitably. Two small fans for supplying cooling air to a condenser are provided at positions adjacent to an evaporating dish and a compressor, respectively. In order to improve the evaporation efficiency of the wastewater in the evaporating dish and the cooling efficiency in the compressor, by installing and blowing air blown through these fans toward the evaporator and the compressor separately. It is an object of the present invention to provide a blowing device for a refrigeration mechanism.

[0006]

Means for Solving the Problems In order to solve the above-mentioned problems and achieve the intended object, a blower for a refrigeration mechanism according to the present invention comprises a compressor, a condenser, etc. in a refrigeration mechanism installed inside a machine room. In addition, in an apparatus in which an evaporating dish for receiving and evaporating drainage such as defrost water or dew condensation water is provided at a lower portion of the machine room, a first air supply for supplying cooling air to the condenser is provided.
A fan is installed near the compressor, and a second fan that also supplies cooling air to the condenser is installed near the evaporating dish, and the air blown out from the first fan is directed toward the compressor. And air blown from the second fan is blown toward the evaporating dish.

(Regarding Blower) The blower 36 is
As shown in FIG. 3 to FIG. 5, 2 is attached to a rectangular mounting board 37 that is aligned with the left opening of the cover member 34.
It is composed of basic fans 40 and 44. The first fan 40 includes, for example, a small motor 41 of “shading coil type single phase induction type” and a fan blade 42 made of synthetic resin fixed to a rotating shaft of the motor 41. The mounting blade 37 is fixed to the substrate 37 using a bracket 43 in a state where the fan blade 42 is aligned with a circular opening 39 formed on the rear upper side of the rear portion. The second fan 44 has the same basic configuration as the first fan 40, and is a "shading coil type single phase induction type".
, And a synthetic resin molded fan blade 46 fixed to the rotating shaft of the motor 45. The fan is inserted into a circular opening 39 formed at the front lower side of the mounting board 37. With the blade 46 aligned
It is fixed to the substrate 37 using a bracket 47. Therefore, as is clear from FIGS. 3 and 5, the first fan 40 and the second fan 44 are connected to the condenser 3
2 is disposed substantially diagonally with respect to the air blowing surface,
The fan 40 is installed above the air blowing surface and is located on the right side of the compressor 31. The second fan 44 is installed below the air blowing surface and the evaporating dish 50 is opened through the opening 49. It is located on the upper right.

In the blower 36 of this embodiment having the above-described configuration, the motors 41, 45 of the first fan 40 and the second fan 44 are simultaneously controlled to rotate the respective fan blades 42, 46. The air in the vicinity of the right side of the condenser 32 is sequentially sucked into the cover member 34, and heat is exchanged when passing through the condenser 32 to cool the condenser 32. Of the air that has passed through the condenser 32 and flowed out to the air blowing surface side, the heated air blown to the left side of the mounting board 37 via the first fan 40 is mainly blown to the compressor 31. The heated air that has been attached and provided for cooling the compressor 31 and blown out to the left side of the mounting board 37 through the second fan 44 mainly flows above the evaporating dish 50 through the opening 49. Sprayed, the evaporating dish 50
Of the wastewater stored in the storage section 53 is evaporated.

(Regarding the Evaporating Dish) A mounting portion 28 is formed below the body 15 so as to protrude into the space portion 19 and open forward. Are set so that they can enter and exit from the front side (FIG. 9). As shown in FIGS. 6 and 7, the evaporating dish 50 is made of a synthetic resin having a tray shape as a whole on the premise of the height of the mounting portion 28. A main body 51 having a flat rectangular shape set to have an appropriately small width dimension, and a horizontally long dew receiving section 52 which is connected to the front edge of the main body section 51 and has the same dimension as the width dimension of the refrigerator 10. Are formed integrally, and the whole size is set to correspond to a substantially front half area of the bottom surface of the refrigerator 10. The main body 51 and the dew receiving part 52
Thereby, a storage unit 53 for storing drainage such as defrost water and dew condensation water is defined. In addition, a drain pipe 48 vertically extending downward from the bottom surface of the storage chamber 20 is provided with the opening 4.
The defrosting water and dew water generated by defrosting are discharged into the storage unit 53 through the storage unit 53.

(Main Body) Eaves 57 extending horizontally outward are integrally formed at the upper ends of the left and right side walls 54, 55 and the rear wall 56 of the main body 51.
The overall torsional rigidity and flexural rigidity are improved. A plurality of dam members extending in the left-right direction and the front-rear direction are integrally formed with the bottom plate 58 of the main body 51 in a state where the dam members project at substantially the same height as the depth dimension of the storage portion 53. Is formed. That is, three trapezoidal plate-shaped first dam members 59, 60, 61 extending in the left-right direction are arranged in a zigzag manner substantially at the center of the bottom plate 58 in the front-rear direction. It is roughly divided into two. In addition, each of the first
Before and after sandwiching the dam members 59, 60, 61, three second dam members 62, 63, 64, 65, 66, extending in the front-rear direction, respectively.
67 are arranged in parallel at substantially the same intervals. Thereby, the storage section 53 is divided into approximately eight sections. The ends of the weir members are not connected to each other, and the drainage in the storage unit 53 is discharged from the first weir members 59, 60, 61 or the second weir members 62, 63, 64, 65, 66, 67. The space flows appropriately, and is uniformly stored in the entire storage section 53.

Of the second weir members, the weir members 62, 63, 64, and 65 located at the front and rear left and front and rear centers,
As shown in FIG. 8A, a vertically formed vertical portion 68 is formed.
And an inclined portion 69 inclined downward to the right front side at an angle of about 45 degrees from the top of the vertical portion 68. That is, these second dam members 62, 63, 64, 65
As shown in FIG. 4, when the evaporating dish 50 is set on the mounting portion 28, a portion where the air from the blower 36 is directly blown toward the opening 49 formed in the base plate 25. And extends in a direction orthogonal to the air blowing direction, and the inclined portion 69 directed toward the second fan 44 is inclined in a direction away from the blower 36 as going upward. . As a result, the heated air blown from the second fan 44 is smoothly blown through, and the rising of the drainage on the inclined portion 69 by the wind pressure of the heated air is allowed. (Figure 1
0). In addition, among the second weir members, the weir members 66 and 67 located on the front and rear sides on the right side are, as shown in FIG.
9, the first weir members 59, 60, 61
As in the case of FIG.
(a)).

(Dew Receiving Unit) As shown in FIGS. 3 and 5, when the evaporating dish 50 is set on the mounting unit 28, the dew receiving unit 52 is mounted on a front panel of the machine body 15. 29
It is adapted to appropriately extend forward from the outer surface of the vehicle. The front end of the dew receiving portion 52 is formed with an inclined wall 70 that is inclined downward toward the rear. The dew receiving portion 52 receives, for example, condensed water flowing down along the front surface of the front panel 29 and guides it to the storage portion 53. (FIG. 11). As described above, since the width of the dew receiving portion 52 is set substantially equal to the entire width of the refrigerator 10, when the evaporating dish 50 is set on the mounting portion 28, the front sides of the legs 17, 17 are set. The left and right legs 17, 17 are not visible from the front side of the refrigerator 10 (FIG. 1). At the center of the left and right of the dew receiving portion 52, a finger hook portion 71 for hanging a fingertip when the evaporating dish 50 is put in and out of the mounting portion 28 is formed.

[0017]

Next, the operation of the blower of the refrigeration mechanism according to the present embodiment configured as described above will be described. Prior to the operation of the refrigerator 10, the evaporating dish 50 is easily stored and set simply by pushing the evaporating dish 50 into the placing portion 28 from the front side (FIG. 9). The evaporating dish 5 stored in the mounting section 28 described above
0 indicates that the storage portion 53 of the main body 51 is
At the same time as the opening 49 formed in the
2 is located in front of a space 19 defined below the body 15. Accordingly, the left and right legs 17, 17 are covered by the dew receiving part 52, and the dew receiving part 52 itself is not conspicuous due to the inclined wall 70 formed on the front surface of the dew receiving part 52. Is improved.

In the refrigerator 10 of this embodiment, when the freezing operation by the freezing mechanism 30 is started with the evaporating dish 50 set, the compressor 31 → condenser 3
2 → cooler 33 → compressor 31 and refrigerant circulate,
The cooler 33 is cooled by the heat of vaporization of the refrigerant. Then, the air sent into the space from the storage room 20 by the cool air circulation device 26 becomes cool air by heat exchange with the cooled cooler 33 and is sent out to the storage room 20, and the entire storage room 20 has a predetermined temperature. Is cooled.

On the other hand, in the blower 36 of the present embodiment, when the refrigerating operation of the refrigerating mechanism 30 is started, the motors 41 and 45 of the first fan 40 and the second fan 44 are driven, and the fan blades 42 and 46 are driven. The rotating and sucked air passes through the condenser 32 to cool the condenser 32.
Then, of the air that has been appropriately heated by heat exchange with the condenser 32, the heated air blown out from the first fan 40 is
It is sprayed onto the compressor 31 heated by the freezing operation, and is used for cooling the compressor 31. On the other hand, the condenser 32
The heated air blown out of the second fan 44 out of the air whose temperature has been appropriately increased by the heat exchange with the air is blown through the opening 49 above the storage section 53 in the evaporating dish 50.

In the refrigerator 10 of the embodiment, when the front door 21 is opened and closed, and the articles to be refrigerated are put in and out of the storage room 20, the temperature difference between the outside air temperature and the temperature inside the storage room 20 causes the front door 21 to open and close. Dew condensation occurs on the outer surfaces of the glass plate 24 at the door 21 and the rear door 22. The condensed water flows down along the glass plate 24, is collected at the bottom of the storage chamber 20, and is discharged to the storage section 53 of the evaporating dish 50 via the drain pipe 48. In addition, since the drainage by the dew condensation water hardly occurs at a time, it does not go to the entire storage unit 53,
The blowing of the heated air blown out through the second fan 44 in the blower 36 evaporates in a relatively short time.

On the other hand, if the refrigerating mechanism 30 is continuously operated for freezing, the frost grows in a layer on the surface of the cooler 33 and the cooling capacity is reduced. If the amount exceeds a predetermined value, a defrosting operation is performed. The defrost water generated by this defrosting operation is once collected on the bottom surface of the storage chamber 20, and then discharged to the storage section 53 of the evaporating dish 50 via the drain pipe 48. Since the drainage due to the defrost water is generated in a relatively large amount by one defrosting operation, the drainage is stored in a state where the drainage reaches the entire storage unit 53, but the first weir members 59, 60, 61 and the second weir member 6
2, 63, 64, 65, 66, 67 project upward from the surface of the drainage water. Then, when the heated air blown out through the second fan 44 in the blower 36 is blown against a predetermined amount of wastewater stored in the storage unit 53,
Due to the wind pressure of the heated air, a part of the drainage rides on the inclined portion 69 of the second weir members 62, 63, 64, 65 (FIG. 10). As a result, the area of the drainage surface (the contact area with the heated air) increases, so that the evaporation efficiency is improved and the time required for the evaporation of the wastewater is reduced.

On the other hand, when the wastewater stored in the storage section 53 is to be discarded, the evaporating dish 50 is pulled out to the front side of the refrigerator 10. Then, when the evaporating dish 50 pulled out from the mounting portion 28 is lifted and transported, if the balance is lost and the evaporating dish 50 is tilted back and forth, the first weir member 59 projecting from the surface of the drainage water. , 60, 61 prevent the entire drainage from moving in the front-rear direction.
Spilling from zero is preferably prevented. When the balance is lost and the evaporating dish 50 is tilted left and right,
The second weir members 62, 63, 6 projecting from the surface of the drainage water
4, 65, 66, and 67 prevent the entire drainage from moving in the left-right direction, so that the drainage is prevented from waving and spilling out of the evaporating dish 50.

As described above, in the evaporating dish 50, the storage section 5
The evaporating dish 5 is formed by the first weir members 59, 60, 61 and the second weir members 62, 63, 64, 65, 66, 67 formed in the inside 3.
Even if the evaporating dish 50 is accidentally tilted back and forth or left and right when transporting 0, it is preferable that the entire drainage accumulated in the storage section 53 is prevented from moving, and the wavy drainage spills. Is prevented. Further, in the refrigerator 10 of the embodiment, the wastewater stored in the storage portion 53 of the evaporating dish 50 is evaporated by using the blowing of the heated air blown out from the second fan 44 in the blowing device 36. Therefore, the second weir members 62, 63, 64,
The drainage rises on the inclined portion 69 formed at 65, thereby increasing the contact area with the heated air and improving the evaporation efficiency. That is, the evaporation efficiency can be improved without increasing the outer size of the evaporating dish 50.

Further, in the refrigerator 10, when the evaporating dish 50 is set on the placing portion 28, the dew receiving portion 52 located at the front of the refrigerator 10 extends over the entire width of the refrigerator 10. The front sides of the legs 17, 17 supporting the refrigerator 10 are suitably covered, and the external appearance of the refrigerator 10 as a whole is improved in texture by improving the external appearance. In addition, since the dew receiving portion 52 appropriately extends forward from the front panel 29 of the refrigerator 10,
It is possible to suitably receive the dew condensation or the like adhering to the front surface (outer surface) of the front panel 29 and prevent the floor from getting wet with the dew condensation water. Further, when the evaporating dish 50 is pushed into the back side, the dew receiving part 52 projecting left and right hits the legs 17 and 17 and functions as a stopper, so that the evaporating dish 50 set on the mounting part 28 can be easily positioned. Done.

Further, in this embodiment, the blower 36 for cooling the condenser 32 is provided with the first fan 40 and the second fan 44.
Therefore, it is possible to use low-priced small motors as the motors 41 and 45 for rotating the fan blades 42 and 46, and it is possible to reduce cost and operation noise. Each fan blade 42,
In the case of 46 as well, with the miniaturization, it becomes possible to cope with a synthetic resin molded product, thereby reducing the cost. The air blown from the first fan 40 is supplied to the compressor 31.
And the air blown out from the second fan 44 can be used for evaporating the wastewater stored in the evaporating dish 50, so that the cooling efficiency of the compressor 31 can be improved and the evaporation efficiency of the wastewater can be improved. Become. Further, the first fan 4
0 and the second fan 44 fails, the other fan operates normally and the condenser 32
It is possible to continuously cool the
The freezing operation of the refrigerator 10 does not stop suddenly.

As shown in FIG. 12, if an air guide member 72 is provided above the opening 49 in the base plate 25 (on the side where the second fan 44 blows air), the air is blown out from the second fan 44. Most of the heated air is guided to the evaporating dish 50 side, and the evaporating efficiency of the wastewater stored in the storage part 53 of the evaporating dish 50 can be further improved. Although not shown, the first fan 40 and the second fan 44
However, assuming that the first fan 4 can be attached to the attachment board 37 at an appropriate angle.
In the case of 0, the air outlet side is mounted on the mounting board 37 with the air outlet side directed toward the compressor 31, so that the heated air can be reliably blown to the compressor 31 so that the cooling efficiency is further improved. Can be expected. In addition, in the second fan 44, by mounting the temperature rising air to the storage section 53 by attaching the air blowing side to the mounting plate 37 with the air blowing side directed to the evaporating dish 50, the evaporation efficiency is further improved. Can be expected to be improved.

In this embodiment, a refrigerator is exemplified as an apparatus equipped with a refrigeration mechanism. However, the blower of the refrigeration mechanism according to the present invention may be a variety of apparatuses equipped with a refrigeration mechanism such as a showcase, an air conditioner, and an ice maker. Applicable to

[0028]

As described above, according to the blower of the refrigerating mechanism according to the present invention, since the condenser is cooled by the first fan and the second fan, the fan blades are rotated. This makes it possible to use a low-priced small motor as the motor for driving, and has an advantage that cost and operating noise can be reduced. In addition, with respect to each fan blade, with the miniaturization, it becomes possible to cope with a synthetic resin molded product, thereby making it possible to reduce costs. The air blown from the first fan can be used for cooling the compressor, and the air blown from the second fan can be used for evaporating the wastewater stored in the evaporating dish. There is an extremely beneficial effect that the improvement and the efficiency of the evaporation of wastewater can be improved. Further, even if one of the first fan and the second fan fails, it is possible to continuously cool the condenser by operating the other fan normally. There is also an advantage that driving does not stop suddenly.
