Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator for sending cool air generated by a cooler by a blower.

As disclosed in Japanese Patent No. 1841, a cool air passage is provided behind a refrigerating compartment whose front surface can be opened and closed by a heat insulating door via a partition wall. A cooler for generating cool air is arranged in the cool air passage, and a blower is arranged above the cooler facing the partition wall. An opening is provided in the partition wall in front of the blower, and the blower is driven so that cool air is discharged from the opening into the refrigerator compartment.

[0003]

However, according to the above-mentioned conventional refrigerator, since the wind noise of the blower is immediately transmitted from the opening to the refrigerator compartment, it easily leaks to the outside through the heat insulating door, and the noise of the refrigerator increases. There was a problem. If there is a gap in the thrust direction between the rotating shaft of the blower and the bearing, the rotating shaft moves by the gap. Since the rotation axis of the blower is arranged substantially horizontally, it can be easily moved by an external impact or the like.

For this reason, if the blower is driven in a state where the rotating shaft is separated from the rear end position, the rotating shaft moves to the rear end position due to the reaction force of the blowing. At this time, the rotating portion and the fixed portion collide with each other, generating noise due to a hitting sound. When the rotating shaft is arranged so that the discharge side is lowered, the rotating shaft before rotation is always arranged at the front end position, so that a blow sound is generated each time the blower is started. For this reason, there was a problem that the noise was further increased.

[0005] Further, since an opening is formed in the partition wall facing the blower, cool air discharged by the blower immediately flows into the refrigerator compartment from the opening. For this reason, there is also a problem that the cold air comes into direct contact with the stored material and accelerates the deterioration of the stored material due to drying and freezing.

Further, when the indoor temperatures of the refrigerator compartment 11 and the vegetable compartment 12 are within a predetermined range, the compressor 20 is used only for cooling the refrigerator compartment 13 so that the refrigerating capacity of the refrigerator compartment 13 can be further increased. .

Further, since the coolers 21 and 25 are arranged in parallel, it is possible to simplify connection of piping through which the refrigerant flows. That is, many of the welding locations can be provided in the machine room 30 in which the compressor 20 is disposed, so that productivity and maintainability are improved. Reference numerals 75 and 76 denote temperature sensors for detecting the temperatures in the refrigerator compartment and the freezer compartment.
, The compressor 20 is driven and the on-off valve 78 is opened and closed. 77 is a condenser 71

1 and 2, a defrost heater 6 for defrosting the coolers 21 and 25 is provided below the coolers 21 and 25.
1, 62 are provided. 63 and 64 are drain receiving members that receive defrost water. A drain hose (not shown) is connected to a lower portion of the drain receiving member 63. A drain hose 68 is connected to a lower portion of the drain receiving member 64.

The bottom of each drain hose is a bottom plate 8
3 is drawn out to the machine room 30 side and connected by a drain pipe 69. The bottom plate 83 is formed continuously with the back plate 2 e and covers the outside of the bottom surface of the freezing compartment 13. The outlet at the tip of the drain pipe 69 is guided above an evaporating dish 91 arranged facing the bottom of the freezing compartment 13. As a result, the drain water is stored in the evaporating dish 91 and evaporates.

The cooler 21 is disposed in the cool air passage 23, and the cool air passage 23 is formed by the inner box 2b and the evaporation cover 33 made of a resin molded product. Blower 22
Is disposed above the cooler 21 in the cool air passage 23.
The cool air passage 23 communicates with the freezer compartment 13 through discharge ports 13a, 13c and a return port 13b provided on the back plate 33a of the freezer compartment 13.

The space between the evaporator cover 33 and the back plate 33a is partitioned by a protruding wall 33c protruding from the evaporator cover 33. As a result, the ejection ports 13a and 13c are separated from the return port 13b.

FIG. 4 shows details of the periphery of the cooler 25. The cooler 25 is arranged in the cool air passage 27, and the blower 26 is arranged above the cooler 25. The blower 26 is composed of a flat type axial flow blower. In the drawing, the discharge surface is about 20 ° with respect to the vertical direction so that air is sucked from the lower right and discharged in the upper left direction.
Mounted at an angle.

The lower part of the cool air passage 27 is formed by a cooling plate 42 which is a partition wall forming the back wall of the refrigerator compartment 11 and the inner box 2b, so that cool air is guided to the cooler 25. The upper part of the cool air passage 27 is separated forward and backward by a partition wall 27a provided between the cooling plate 42 and the inner box 2b. The cooling plate 42 and the partition 27a are formed by sheet metal processing of a metal plate such as aluminum or stainless steel.

Thus, a pressure chamber 27b is formed on the discharge side of the blower 26, and the partition wall 27a and the cooling plate 42 are formed.
And a space 27d is formed between them. The cooling plate 42 is provided with a discharge port 42a on the front surface of the space 27d.
The blower 26 includes an attachment member 27 fixed to a partition 27a.
c and is attached to the partition wall 27a.

It is desirable that the angle of inclination of the blower 26 be 15 ° to 25 °. Thereby, even if there is a gap in the thrust direction between the rotating shaft of the blower 26 and the bearing, the rotating shaft is stably arranged on the suction side (lower right in the figure) by the weight of the fan. Therefore, even if a reaction force of the blower acts on the rotating shaft due to the driving of the blower 26, a force is applied in the direction of the suction side. Can be prevented.

Further, by setting the inclination angle to 25 ° or less, a thrust load applied to the bearing is small, and an inexpensive bearing having a simple structure can be used. Moreover, the refrigerator 1 can be space-efficient without increasing the width of the cool air passage 27 in the front-rear direction.

A ceiling cool air passage 57 communicating with the cool air passage 27 is provided at a ceiling portion of the refrigerator compartment 11.
Reference numeral 7 is formed by an upper plate 43 made of a resin molded product and the inner box 2b. The cooling plate 42 and the upper surface plate 43 are provided with discharge ports 42a, 43a. An illumination lamp (not shown) covered with a transparent illumination cover 53 is provided at the center of the ceiling of the refrigerator compartment 11 to illuminate the refrigerator compartment 11.

The upper portion of the partition wall 27a is provided so as to cover the entire front surface of the blower 26. The lower part of the partition wall 27a is connected to a position close to the lower front part of the blower 26. Thus, the width of the cold air passage 27 in the front-rear direction is not increased. Outflow port 27 of pressure chamber 27b
g is formed between the upper end of the partition wall 27a and the inner box 2b, and the width B of the outlet 27g is 1 / the diameter A of the opening of the blower 26.
2 or less. The width of the outlet 27g in the left-right direction is substantially equal to the width of the ceiling cool air passage 57.

For this reason, the cool air delivered by the blower 26 is guided to the partition 27a, and gradually spreads in the left-right direction before reaching the outlet 27g. Thereby, the cool air smoothly flows into the ceiling cool air passage 57 and the space 27d without lowering the air blowing efficiency due to the generation of a vortex or the like. Then, cool air is discharged from a wide range in the left-right direction of the refrigerator compartment 11 through the openings 42a and 43a, and the inside of the refrigerator compartment 11 is uniformly cooled.

Further, a recessed portion 2f formed by recessing the inner box 2b is formed behind the blower 26. Thereby, even if the lower end of the blower 26 on the suction side is disposed behind the front surface of the cooler 25, the distance C between the lower end of the blower 26 on the suction side and the inner box 2b is sufficiently ensured, and the cool air is recessed 2f. It is efficiently sucked through.

Therefore, the space efficiency can be improved by reducing the width of the cool air passage 27 in the front-rear direction without lowering the air blowing efficiency. Moreover, since the cool air sucked by the blower 26 has a small heat capacity, even if the thickness of the rear heat insulating material 2c is reduced by the concave portion 2f, a sufficient heat insulating effect can be obtained, and the rear side of the cooler 25 which becomes extremely low temperature. Since the thickness of the heat insulating material 2c can be made sufficiently large, a sufficient heat insulating effect can be obtained also in this portion.

By arranging the upper end of the blower 26 on the suction side in the recess 2 f, even if the lower end of the blower 26 on the suction side is located behind the front surface of the cooler 25, the inclination angle of the blower 25 can be reduced. Can be set in the range of 15 ° to 25 °. At this time, the vertical distance between the upper end of the cooler 25 and the lower end of the blower 26 is
前後 of the width in the front-rear direction.

As a result, the space in the front-rear direction can be used efficiently, and the flow area of the cool air can be reasonably secured, and the flow direction of the cool air can be changed without causing a large decrease in the suction efficiency of the blower 26. By setting the angle θ of the straight line connecting the upper end of the front surface of the cooler 25 and the lower end of the suction side of the blower 26 to the vertical direction to be about 30 °, a cooling air circulation area can be secured without increasing the space in the vertical direction. can do.

1 and 2, a water supply pump 66 for supplying water to the ice maker 70 is disposed on the left side of the cold air passage 27, and a water supply tank (not shown) is set in front of the water supply pump 66. It has become. An ice temperature duct 60 that branches from the discharge side of the blower 26 and guides cool air to the back of the ice temperature chamber 14 is provided on the right side of the cool air passage 27.

The compressor 2 is located behind the vegetable compartment 12.
0, a storage box 58a for storing an electric circuit 58 for driving and controlling the blowers 23 and 26 and the like is provided.
The back of the storage box 58a is closed by an electrical cover 58b, and the periphery of the storage box 58a is covered by a heat insulating material 2c. The heat insulating material 2c blocks heat generated by the electric circuit 58.

The upper and lower surfaces of the storage box 58a are formed to be inclined. Thereby, the inner box 2b is inclined, and the cool air passing through the cool air passages 27 and 23 smoothly changes the direction,
The flow resistance is reduced by suppressing the generation of vortices.

In the refrigerator 1 having the above configuration, the compressor 20
Is cooled by the cooler 21 by the driving of the blower 2.
2 is driven, the air in the freezing room 13 returns to the return port 13b.
From the cooling air passage 23. The air is cooled by exchanging heat with the cooler 21 and discharged to the freezing compartment 13 through the discharge ports 13a and 13c. Thereby, the inside of the freezing room 13 is cooled to, for example, −20 ° C.

When the blower 26 is driven, the air in the vegetable compartment 12 is sucked into the cool air passage 27 from the return port 12b.
The air is cooled by exchanging heat with the cooler 25, and is cooled by the cool air passage 2.
7 through the space 27 and the ceiling cool air passage 57, and is discharged from the discharge ports 42a and 43a into the refrigerator compartment 11.

Further, since the cooling plate 42 is made of metal, the sound insulation effect can be enhanced as compared with the resin molded product, and a part of the cold heat of the cool air flowing through the cool air passage 27 is passed through the cooling plate 42. The heat is released into the refrigerator compartment 11 as cold heat. Thereby, the inside of the refrigerator compartment 11 is efficiently and uniformly cooled to, for example, 3 ° C. by the cool heat discharged from the cooling plate 42 and the cool air discharged from the discharge ports 42 a and 43 a. Cooling plate 42
Any material may be used as long as it is a good thermal conductor having high thermal conductivity, and a ceramic material, a resin material impregnated with a metal filler, rubber kneaded with lead, tin, or the like may be used.

The cool air in the refrigerator compartment 11 is discharged to the front of the vegetable compartment 12 through the communication passage 12a through the front surface of the shelf 45. Then, the inside of the vegetable compartment 12 is cooled down from the front of the storage container 54, and the cool air is circulated from the return port 12b to the cool air passage 27. The cool air discharged from the discharge ports 42a and 43a into the refrigerator compartment 11 is deprived of food and the like by the time the cold air flows into the vegetable compartment 12. Thereby, the refrigerator compartment 1
The temperature of the cold air circulating inside 1 rises, and the raised cold air flows into the vegetable room 12, so that the inside of the vegetable room 12
Cool to ° C.

Also, the cool air sent from the blower 26 is immediately passed through the ice temperature duct 60 to the ice temperature chamber 1 through the discharge port 60a.
4 is discharged in an appropriate amount. Thereby, the temperature in the ice greenhouse 14 can be maintained at, for example, -1 ° C. The temperature of the ice greenhouse 14 is reduced to 0 ° C. by reducing the amount of cold air discharged inside.
When it is near, it becomes a chilled room, and when the amount of cold air is further reduced and the room temperature is around 5 ° C., it becomes a vegetable room. The amount of cool air can be changed by opening and closing a door pivotally supported so as to cover the discharge port 60a.

According to the present embodiment, the blower 26 is disposed obliquely to discharge cool air obliquely upward,
Since the partition wall 27a is erected in the forward direction, the cold air can be smoothly guided upward and collide with the partition wall 27a to block the wind noise of the blower 26 without lowering the blowing efficiency.

Thus, unlike the conventional example, the wind noise is not immediately transmitted to the refrigerator compartment 11 and the noise of the refrigerator 1 can be reduced. In addition, by providing the partition wall 27a upright so as to cover the entire surface of the blower 26, most of the wind noise together with the cool air discharged from the blower 26 can collide with the partition wall 27d. Therefore, the noise reduction effect due to the collision is increased, and the sound insulation effect can be further improved.

Further, by providing a space 27d between the cooling plate 42 serving as a partition wall between the refrigerator compartment 11 and the cool air passage 27 and the partition wall 27d, the noise transmitted to the cooling plate 42 is further reduced and the sound insulation effect is provided. Can be improved.

As the partition wall 27a, a foam such as styrene foam, a porous body such as porous ceramic, or a sound absorbing material such as synthetic rubber having low temperature resistance may be used. Further, the above-described sound absorbing material, a fibrous sound absorbing material such as glass wool, a sponge-like sound absorbing material such as a soft urethane foam, a rubber kneaded with lead or tin, or the like may be fixed to a metal plate or the like.

In this way, the wind noise of the blower 26 can be absorbed and the sound insulation effect can be further improved. In this case, since the foam such as styrene foam has a heat insulating effect, when the temperature of the cool air generated by the cooler 25 is low, the transmission of the cool heat to the space 27d is suppressed to reduce the cooling plate 42.
Dew condensation can be prevented.

The cool air discharged from the blower 26 passes through the ceiling cool air passage 57 and the space 27d, and the opening 42a,
Since the air is discharged from 43a, the distance over which the cool air flows increases, and noise is absorbed during the flow. Furthermore, since the extremely low-temperature cold air does not directly contact the storage, deterioration of the storage due to drying or freezing can be prevented.

Further, when the cool air is discharged only from the opening 43a, the cool air further discharges the cool heat while passing through the ceiling cool air passage 57, so that the temperature rises to further prevent the stored product from drying. Further, since the cool air gradually spreads from the pressure chamber 27b toward the ceiling cool air passage 57 and flows out smoothly, it is possible to prevent an increase in noise and to reduce the noise by lowering the flow velocity.

In the present invention, the refrigerator compartment 11 and the vegetable compartment 12 are cooled by the same cooler 25, but the refrigerator compartment and the freezer compartment may be cooled by the same cooler. . Further, as the coolers 21 and 25, an evaporator, a cooler using a Peltier method, or a cooler using another cooling method can be used.

Further, the cooling plate 42 and the partition 27a are connected to the refrigerator compartment 1
The back wall may be formed of a resin molded product generally used to form the back wall. By doing so, the heat conductivity of the cooling plate 42 is reduced and the effect of uniformly cooling the refrigerator compartment 11 is reduced, but otherwise the same effect as described above is obtained.

[0059]

According to the present invention, the blower is arranged obliquely and discharges the cool air obliquely upward and the partition wall is erected in the front, so that the cool air is smoothly guided upward and blown. It is possible to cut off the wind noise of the blower by colliding with the partition without lowering the efficiency.

Thus, unlike the conventional example, the wind noise is not immediately transmitted to the storage room, and the noise of the refrigerator can be reduced. By arranging the partition so as to cover the entire surface of the blower, most of the wind noise together with the cool air discharged from the blower can collide with the partition. Therefore, the noise reduction effect due to the collision is increased, and the sound insulation effect can be further improved.

By inclining the blower, even if there is a gap in the thrust direction between the rotating shaft and the bearing of the blower, the rotating shaft is stably arranged on the suction side by the weight of the fan. Therefore, even if the reaction force of the blower acts on the rotating shaft due to the drive of the blower, the force is applied in the suction side direction. Occurrence can be prevented. Further, since the cool air is not immediately discharged to the storage room, the cool air at a very low temperature does not directly contact the stored material, so that deterioration of the stored material due to drying or freezing can be prevented.

Further, according to the present invention, by providing a space between the partition wall between the storage room and the cool air passage and the partition wall, the noise transmitted to the partition wall can be further reduced and the sound insulation effect can be improved.

Further, according to the present invention, since the partition wall is made of a good heat conductor, a part of the cool heat of the cool air flowing through the cool air passage is released as cold heat into the storage room through the partition wall. Thus, the storage room is uniformly cooled by the cold heat released from the partition wall. Further, the sound insulation effect can be improved as compared with a resin molded product or the like.

Further, according to the present invention, since the partition wall is made of a good heat conductor, a part of the cold heat of the cool air flowing through the cold air passage is transmitted to the space through the partition wall, and is discharged from the space through the partition wall by the cold heat. The storage room is cooled uniformly.

Further, according to the present invention, the width of the cool air passage in the left-right direction is made larger than the opening diameter of the blower at the discharge side of the blower, and the cool air passage is narrowed by the partition in the side cross section. Is smaller than the opening diameter of the blower, so that the cool air sent out by the blower gradually spreads in the left-right direction before reaching the outlet, so that the cool air can flow out smoothly without lowering the blow efficiency. . Then, cool air is discharged into the storage chamber from a wide range, and the storage chamber is uniformly cooled.

Further, according to the present invention, since the cool air is guided into the ceiling cool air passage by the partition wall, the cool air can smoothly flow into the ceiling cool air passage, and a decrease in the air blowing efficiency due to the generation of a vortex can be prevented. In addition, while the distance in which the cool air circulates increases, the wind noise of the blower is absorbed while the cool air circulates, thereby reducing noise.

Further, according to the present invention, since the concave portion is provided behind the blower, the thickness of the heat insulating material behind the cooler, which becomes extremely low in temperature, can be made sufficiently thick. Further, even if the lower end of the blower on the suction side is located rearward of the front surface of the cooler, a sufficient distance between the lower end of the blower on the suction side and the inner box can be ensured to efficiently suck cool air.

Therefore, the space efficiency can be improved by reducing the width of the cool air passage in the front-rear direction without lowering the air blowing efficiency. At this time, since the cool air sucked into the blower has a small heat capacity, a sufficient heat insulating effect can be obtained even if the thickness of the rear heat insulating material becomes thinner due to the concave portion.

Further, according to the present invention, by arranging a part of the blower in the recess, the inclination angle of the blower can be inclined to a desired angle even if the blower is arranged rearward.

Further, according to the present invention, since the partition is formed of the sound absorbing material, the sound insulating effect can be further improved.
