It consists of two members of the member 82. If the surface of the refrigerator compartment panel 81 becomes excessively cold, dew condensation may occur when the door 2a is opened and outside air invades, and thus the first refrigerator compartment duct is formed by the duct forming member 82 having high heat insulating performance. (11) The cooling of the refrigerator compartment panel 81 by the cold air which flows through the 2nd refrigerator compartment duct 12 is suppressed.

The distance L7a (L7a = 100 mm in this embodiment) from the center plane X to the left end of the 1st refrigerator compartment duct 11 shall be 1/3 or less of the distance L1 between both wall surfaces, and it is the 2nd refrigerator compartment from the center plane X. The distance L7b (L7b = 80 mm in this embodiment) to the right end of the duct 12 is equal to 1/3 or less of the distance L1 between both wall surfaces.

Although the low temperature cold air flows through the cold air duct, the first refrigerating chamber duct 11 and the second refrigerating chamber duct 12 are located in the front projection surface of the vacuum insulator 26 having high thermal insulation performance so as to suppress intrusion of heat through the cold air duct. Is installing. As described above, since the surface of the heat dissipation pipe 25 is hotter than the outside, the first refrigerating chamber duct 11 through which hot and cold air flows so as to suppress the intrusion of heat into the furnace from the heat dissipation pipe 25, The second refrigerating chamber duct 12 is provided at a distance of 50 mm or more, which is a predetermined distance which cannot be affected by the temperature from the heat dissipation pipe 25. That is, in the refrigerator 1 of this embodiment, since the vacuum heat insulating material 26 and the heat dissipation pipe 25 are provided in the back, the 1st refrigerator compartment duct 11 and the 2nd refrigerator compartment duct 12 are substantially center of the back surface.

The second discharge port 102 is also provided with two redirecting members 102a each having a thickness t inclined at an angle θ3 in the counterclockwise rotational direction (left to right direction) on the ground plane X. Thus, the 1st discharge port 101 and the 2nd discharge port 102 are asymmetrical structure with respect to the center plane X. As shown in FIG.

In order not to affect the flow path in the 1st refrigerator compartment duct 11, the depth dimension of the deflecting member 101a and the deflecting member 102a is the refrigerator compartment duct structure member which spaces apart the 1st refrigerator compartment duct 11 and the refrigerator compartment 2 from it. It is made the same as the thickness of 80.

Next, the flow of cold air discharged from the first discharge port 101 and the second discharge port 102 will be described.

Regarding the flow of cold air in the width direction, since the first discharge port 101 and the second discharge port 102 exhibit the same tendency, the cold air discharged from the first discharge port 101 will be described here.

As shown in FIG. 4, the clearance gap formed by the left-right side wall surface of the refrigerating chamber 2 and the door 2a is set as the area | region C. As shown in FIG. This area C is likely to invade heat from the outside due to the heat conduction from the gasket 120 or the surface of the door 2a and the heat insulating box 10, and furthermore, the door 2a and the heat insulating image. Since both ends of the self 10 are places where the vacuum heat insulating material 26 is not arrange | positioned, it is an area | region where heat insulation performance is low.

The cold air discharged from the first discharge port 101 provided in the area A is discharged at an angle of inclination θ1 in the counterclockwise rotational direction (from left to right) on the ground with respect to the center plane X, and is discharged from the center of the shelf 39c. It passes through the surface X and flows from the area A to the area B. In other words, at least part of the first discharge port 101 is formed in the area A, and the air discharged from the first discharge port 101 is directed from the area A to the area B. In addition, the structure which directs the air discharged from the 1st discharge port 101 toward the area B from the area | region A is a structure by the shape of the 1st discharge port 101 itself, or a moving louver is attached to the 1st discharge port 101. FIG. The structure to be provided may be sufficient, and the structure is not specifically limited.

Reach between 121 and the door liner 122. The cold air reaching the door 2a diffuses while flowing along the door 2a and is diverted to the back side by the door liner 121 and the door liner 122, so that the cold air cannot reach the region C.

As mentioned above, although the structure of the refrigerator 1 of this embodiment and the flow of cold air discharged from the 1st discharge port 101 and the 2nd discharge port 102 which were provided in the refrigerating chamber 2 were demonstrated, Next, this embodiment The effect of the refrigerator 1 will be described.

In the refrigerator 1 of this embodiment, as shown in FIG. 4, the 1st thing installation part (shelf 39c) in the heat insulation box 10, and the 1st thing installation part (for the door 2a) are shown. The pocket 32 is provided, and the air discharged from the first discharge port 101 passes through the center plane X in the width direction of the refrigerating chamber 2 within the range of the first storage installation portion. That is, the 1st discharge port 101 discharges cold air in front of a right inclination, and makes it pass the center surface X of the width direction within the range of the shelf 39c. As a result, a refrigerator having high energy saving performance can be obtained in which the wall surface in the refrigerating chamber 2 is not excessively cooled, but the intrusion of heat from the outside is reduced.

Next, with reference to the flow of cold air of the conventional refrigerator shown in FIG. 6, the effect of this invention is demonstrated.

6A, 6B, and 6C are diagrams each showing an example of the flow of conventional cold air in the refrigerating chamber. 6A and 6B show a case in which cold air flows along the inner wall surface of the refrigerating chamber to cool the inside, and FIG. 6C illustrates a case in which cold air is discharged toward the front to cool the inside.

In FIG. 6A, the cold air duct 11a provided with the discharge port 104 is provided in the back surface of the refrigerating chamber 2, and cold air is discharged from the discharge port 104 toward both sides.

The cold air discharged from the discharge port 104 first flows along the rear surface of the refrigerating chamber 2 and then reaches the region C in front of the refrigerating chamber 2 along both sides. In such a flow of cold air, the rear surfaces of both sides of the cold air duct 11a are cooled by the low temperature cold air immediately after the discharge, and the intrusion of heat through the rear wall is likely to increase due to the temperature difference between the rear surface of the refrigerating chamber 2 and the outside. . Moreover, even after cold air flows along the back surface, since it flows along a side surface, the invasion of the heat from a side surface also tends to become large. Moreover, since the cold air which passed the side surface reaches the area | region C with low heat insulation performance, the invasion of the heat from this part tends to become large.

In FIG. 6B, a cold air duct 11b including a discharge port 105a and a discharge port 105b is provided on the rear surface of the refrigerating chamber 2 so as to prevent cold air from flowing along the rear surface of the refrigerating chamber 2. Cool air is discharged from the discharge port 105b toward the inclined front side of the refrigerating chamber 2.

Intrusion of heat from the back surface of the refrigerating chamber 2 is suppressed, but from the discharge port 105a provided on the left side from the center plane X, cold air is discharged to the left inclined front and from the discharge port 105b provided on the right side from the center plane X. Since the cold air is discharged to the right inclined front side, the cold air easily reaches the front side surface. After the cool air discharged from the discharge port 105a and the discharge port 105b reaches both sides of the front side of the refrigerating chamber 2, the cool air flows in the same manner as the flow of cold air described with reference to FIG. 6A. The temperature difference on the outside becomes large, and heat invasion tends to become large.

In FIG. 6C, the cold air duct 11c provided with the discharge port 106 is provided on the center surface X, and cold air is discharged from the discharge port 106 toward the front of the refrigerating chamber 2. In this case, since the distance from the discharge port 106 to the door 2a is short, before the cold air diffuses sufficiently, the area D of the door 2a is reached and the area D is excessively cooled, so that the area D Due to the high temperature difference, the intrusion of heat through the door 2a tends to be large.

On the other hand, as shown in FIG. 4, the cold air discharged from the 1st discharge port 101 of this embodiment is the center plane of the width direction of the refrigerating chamber 2 within the range of the shelf 39c in which a storage object is put. Pass through X Therefore, first, the vicinity of the center of the shelf 39c through which cold air flows is cooled. Next, the circumference | surroundings are gradually cooled in order of the storage object of the side surface of the shelf 39c, and the side surface by the spread of heat, radiation, etc. by the temperature difference of the vicinity of the center of the shelf 39c, and the surroundings. Thereby, compared with the flow of cold air shown to FIG. 6A or 6B, a storage object can be cooled efficiently without overcooling the back surface or side surface in the refrigerating chamber 2.

On the other hand, when the storage is excessively full, cold air may diffuse by the storage and the flow shown in FIG. 4 may not be obtained. However, first of all, the storage in which cold air reaches is cooled to become a low temperature, and the surroundings gradually become a low temperature, so that the storage can be cooled more efficiently than the wall surface as in the above.

Further, the deflecting member 101a discharges cold air in a direction inclined at an angle θ1 in the counterclockwise rotational direction (from left to right) on the ground with respect to the center plane X. L6 = [1 / (cosθ1)] L6a when the distance L6 from the cold air inclined to the angle θ1 and reaches the door 2a from the first discharge port 101 to L6a is set to a distance L6a. It becomes and becomes long by [1 / (cos (theta) 1)] times. That is, compared with the flow of cold air shown in FIG. 6C, since the distance from the discharge port to the door 2a becomes longer, the invasion of heat from the door 2a can be reduced.

As described above, in the refrigerator 1 of the present embodiment, (1) the discharge of cold air from the discharge port to the right inclined forward direction, (2) the discharged cold air is within the range of the shelf 39c, and the refrigerating chamber 2 Passing through the center plane X in the width direction of the film is characterized by the flow of cold air, and by these flows, the intrusion of heat from the back, the side, and the door can be suppressed, and a refrigerator having high energy saving performance can be obtained.

On the other hand, in the refrigerator 1 shown in FIG. 3, the shelf 39b provided above the shelf 39c is arrange | positioned so that the 1st discharge port 101 may approach. Similarly, the shelf 39c disposed above the shelf 39d is disposed so as to be close to the second discharge port 102.

Since the storage is placed on the shelves 39, the flow path of the cold air is hard to be clogged at the upper side as compared to the lower part of the space partitioned by each shelf. Therefore, if the shelf 39 is arranged so that each discharge port is located in the upper portion of each space, the discharge port becomes difficult to be clogged. On the other hand, since the cold air is discharged from the upper part of each space, the cold air easily flows through the upper part of the stored object while maintaining directivity. That is, even if the stock is placed on the flow of cold air, when cold air is discharged as shown in Fig. 6C, it is easy to reach the door 2a before the cold air diffuses sufficiently. Therefore, since the directivity of cold air hardly changes in the refrigerator of the said structure, this embodiment is especially effective.

In addition, as shown in FIG. 2, even when the first discharge port 101 is discharged upward, since the upper portion of the stored material easily flows, the present embodiment is particularly effective similarly.

In addition, in the refrigerator 1 of this embodiment, the cold air discharged from the 1st discharge port 101 and the 2nd discharge port 102 reaches between the door liner 121 and the door liner 122 of the refrigerating chamber 2. It is adjusted so that blowing to the area C is suppressed. As described above, the area C is an area in which heat is likely to invade due to heat conduction from the door packing 120 or the like. On the other hand, in the flow of cold air shown in Figs. 6A and 6B, since the region C is reached, intrusion of heat from this portion tends to be large. Therefore, in the flow of cold air of the refrigerator 1 of this embodiment, compared with the flow of cold air shown to FIG. 6A or FIG. 6B, invasion of the heat through a door liner and both wall surfaces can also be reduced.

The other effect of this embodiment is demonstrated. In the refrigerator 1 of this embodiment, the cold air flow of the up-down direction is also considered. As shown in FIG. 2, the cold air discharged from the 1st discharge port 101 and the 2nd discharge port 102 is adjusted so that it may reach between the upper and lower sides of the door pocket 32 provided in the up-down direction of the door 2a. have. Accordingly, since the discharged cold air does not directly reach the wall surface of the door pocket 32, the cold air does not reach the wall surface of the door pocket 32, and the cold air does not reach the area C along the wall surface. A refrigerator with high energy saving performance can be obtained. The reason will be described below with reference to FIG. 7.

It is a figure which shows the flow of cold air, when discharge cold air from a 1st discharge port is blown in the trailing edge of a door pocket. Here, the trailing edge of the door pocket 32 is a side wall of the door pocket 32 protruding toward the rear of the storage compartment. Although cold air is discharged from the first discharge port 101 to the right inclined front side, the discharged cold air may reach the trailing edge of the door pocket 32 and flow along the trailing edge of the door pocket 32 to reach the region C. FIG.

On the other hand, as shown in FIG. 2, in the refrigerator 1 of this embodiment, the air pocket discharged from the 1st discharge port 101 and the 2nd discharge port 102 has the door pocket provided in the up-down direction of the door 2a. It is adjusted so that cold air may reach between (32). Thereby, cold air blowing to the area | region C along the door pocket 32 is suppressed, and cold air can reach between the door liners of the door 2a with high heat insulation performance. That is, when cold air reaches between the door pocket 32 provided in multiple numbers in the up-down direction of the door 2a, it becomes a refrigerator with high energy saving performance which reduced the invasion of the heat from the outside.

In the refrigerator 1 of this embodiment, energy which suppressed the invasion of the heat from the side surface by discharging cold air from the discharge port to the right inclined front and passing the discharged cold air inside the door liner of the area C of the refrigerating chamber 2 A refrigerator with high saving performance is realized. In addition, as shown in FIG. 4, the plurality of deflecting members 101a are provided inside the first discharge port 101 to direct the flow of cold air.

Next, another cold air | cooling direction means is demonstrated with reference to FIG. 8A, FIG. 8B, FIG. 8C. The cold air directing means has a configuration in which the discharge port itself is inclined in addition to the configuration in which the plurality of deflecting members 101a are provided inside the first discharge port 101 to direct the cold air, as in the refrigerator of the present embodiment (see FIG. 4). And a configuration in which cold air is discharged from the discharge port and then directed.

8A, 8B, and 8C are diagrams showing examples of other cold air directing means according to the embodiment of the present invention.

First, the refrigerator shown in FIG. 8A has provided the 1st refrigerator compartment duct 11 provided with the discharge port 107 in the area | region A. FIG. Further, the discharge port 107 and the first refrigerating chamber duct 11 are inclined θ4 in the counterclockwise rotational direction (front to rear) on the ground with respect to the back surface. As a result, cold air is discharged in front of the right tilt to form a flow of cold air as shown in FIG. 4.

Next, in the refrigerator shown in FIG. 8B, the discharge port 108 which discharges cold air toward the right side surface, and the cold air duct 11 provided with the discharge port 108 are provided in area | region A, and the cold air of the discharge port 108 is redirected. On the right side of the discharge port 108, the deflecting member 108a to be made is provided to face a predetermined distance (for example, within 50 mm) from the discharge port 108. The cold air discharged from the discharge port 108 toward the side surface changes in the direction by the deflecting member 108a and flows forward to the right slope. Accordingly, the flow of cold air as shown in FIG. 4 is formed.

Next, in the refrigerator shown in FIG. 8C, the ejection opening 109 provided with the plurality of redirecting members 109a therein so as to be inclined at θ5 in a counterclockwise rotation direction (from left to right) on the ground with respect to the center plane X; The refrigerating chamber duct 11 provided with the discharge port 109 is provided in the vicinity of the center. The left end of the discharge port 109 is to the left of the distance L2b than the center plane X, and the right end of the discharge port 109 is to the right of the distance L2c than the center plane X. That is, it is the example provided so that the discharge port 109 provided with the cold air directing means like 1st Embodiment may be included in both the area | region A and the area | region B. As shown to FIG.

As described above, in order to obtain a refrigerator having high energy saving performance, the cold air discharged to the right inclined front needs to flow through the center plane X. If the outlet port 109 is provided so that at least a part thereof is located in the region A, even if the cold air is discharged in front of the right inclination, a part of the cold air flows through the central plane X, and the above-described effects can be obtained. However, since cold air is discharged to the right inclined front side, if the distance between the discharge port 109 and the right side is short, the right side and the region C are easily cooled, so the distance L2c is preferably 1/3 or less of the distance L1 between the both side wall surfaces.

As described above, the cold air directing means shown in Figs. 8A, 8B and 8C forms the flow of cold air passing through the region C by directing the cold air to the right inclined forward direction, thereby providing high energy as in the refrigerator 1 of the present embodiment. Saving performance can be obtained. The same effect can also be obtained by providing a discharge port so as to be included in the area B, and discharging cold air in front of the left inclination to pass the area A.

In addition, like the refrigerator 1 of this embodiment, when the opening part of the 1st discharge port 101 is divided into the some deflecting member 101a, it opens in the 1st refrigerator compartment duct 11 from the opening part of the 1st discharge port 101. FIG. You can avoid accidentally dropping your storage.

In addition, like the refrigerator 1 of this embodiment, in addition to the 1st refrigerator compartment duct 11 provided with the 1st discharge port 101 (cool air is supplied to the center of the refrigerator compartment 2 with a relatively high frequency of use), a 2nd refrigerator compartment By providing the second refrigerating chamber duct 12 (the supply of cold air in the upper part of the refrigerating chamber 2 having a relatively low use frequency) provided with the duct discharge port 110 (the discharging opening in the upper part of the refrigerating chamber), cooling with temperature unevenness can be suppressed. Become.

Moreover, like the refrigerator 1 of this embodiment shown in FIG. 4, the center of the 1st discharge port 101 is provided in the area | region A side, and the mainstream of the cold air discharged from the 1st discharge port 101 is centered. Passing through X, suppressing cooling of the wall surface, suppressing the ingress of heat from the wall surface, and further enhancing the energy saving performance becomes possible.

Moreover, in the refrigerator 1 of this embodiment, it installs so that the whole 1st discharge port 101 may be located in area | region A, and energy saving performance is improved. As shown in FIG. 4, by discharging angle (theta) 1, the discharge distance L6 of cold air becomes long, and cooling of the door 2a can be suppressed. On the other hand, in order to pass through the center plane X to reach the door 2a, the range of the discharge angle θ1 is limited depending on the position of the first discharge port 101. Therefore, by providing the whole of the 1st discharge port 101 in the area | region A of the left side rather than the center plane X, it becomes possible to enlarge discharge angle (theta) 1 and to improve energy saving performance more.

In addition, in the refrigerator 1 of this embodiment, the door hinge (not shown) covered by the door hinge cover 37 is provided in the upper right side of the refrigerator 1 upper part. In this case, since the door 2a is opened from the left side, when the door 2a is opened, air in the refrigerating chamber 2 easily flows out from the left side of the refrigerating chamber 2, that is, the region A. Here, as shown in FIG. 4, since the 1st discharge port 101 is provided in the area | region A, it passes through the center plane X within the range of the shelf 39, and discharges cold air so that it may flow in the area | region B, In the vicinity of the leading edge of (39), the air side of the region B tends to be low. Therefore, by installing the door hinge on the side opposite to the area A in which the first discharge port 101 is provided, the outflow of the air in front of the area B, which becomes relatively low temperature, when the door 2a is opened, thereby suppressing the ingress of heat. can do.

The above is the effect that the refrigerator 1 of the first embodiment has.

Here, the flow of cold air after discharge from each discharge port is judged from the temperature distribution at the time of cooling the refrigerating chamber 2, for example. When cooling the refrigerating chamber 2, first, the part through which cold air passes becomes low temperature, and the circumference | surroundings are cooled gradually. A plurality of temperature measuring points are provided in the refrigerating chamber 2 in the width direction, and the temperature of the air in the refrigerating chamber 2 is measured. The refrigerating chamber 2 is cooled in the state where the temperature of a measuring point is substantially constant, for example, the flow of cold air is confirmed from the temperature distribution in 5 minutes after a cooling start.

It is a figure which shows the example of the method of confirming the flow of cold air. 9B and 9C are temperature distribution of 5 minutes after the cooling start of the positions Y1 and Y2 shown in FIG. 9A, respectively. The center of the depth direction of the shelf 39c, ie, the position of the distance [(L4) / 2] from the trailing edge of the shelf 39c, is indicated by the dashed-dotted line as the center plane Y1. Moreover, let Y2 be the surface parallel to the center plane Y1 including the leading edge of the shelf 39c.

On the center surface Y1 of the shelf 39c shown to FIG. 9B, the minimum temperature is shown in the area | region A. FIG. On the other hand, in the leading edge Y2 of the shelf 39c shown in FIG. 9C, the minimum temperature is shown by the area | region B. FIG. At this time, since Y2 which is closer to the front surface than Y1 shows the lowest temperature position on the right side, it is judged that cold air flows in front of the right inclination. In addition, since at least a part of the first discharge port 101 is in the area A, and the leading edge Y2 of the shelf 39c shows the lowest temperature in the area B, cold air passes through the central plane X within the range of the shelf 39c. I judge it. It can also be confirmed that a flow in which the storage in the shelf 39c is easier to cool than the wall surface is obtained. From the above, it can be determined that the cold air discharged from the first discharge port 101 to the right inclined front passes through the central plane X within the range of the shelf 39c.

Moreover, in the center surface Y1 of the shelf 39c, the minimum temperature is shown at the position closer to the center surface X than the side surface. In this regard, it may be judged that a temperature distribution capable of efficiently cooling the storage of the shelf 39c can be obtained without excessively cooling the side surface.

In addition, in FIG. 9A, the straight line shown by the dotted line in the figure which connected the position which shows the minimum temperature in the center surface Y1 of the shelf 39c, and the position which shows the minimum temperature in the leading edge Y2 of the shelf 39c is the door liner 121 It intersects with door 2a passing through and door liner 122. Thereby, like the refrigerator 1 of this invention, it can be determined that cold air has reached between the door liner 121 (left protrusion) and the door liner 122 (right protrusion).

(Second Embodiment)

Next, the refrigerator 1 of 2nd Embodiment is demonstrated with reference to FIGS. 10-12. The refrigerator 1 of 2nd Embodiment is a so-called French door type refrigerator provided with two doors of the refrigerating chamber 2 to the left and right. In addition, about the structure similar to the refrigerator 1 of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

10 is a front view of the refrigerator according to the second embodiment of the present invention. The refrigerating chamber 2 of 2nd Embodiment is equipped with the 1st door 2b and the 2nd door 2c which divide to the left and right on the front side. Moreover, the rotary partition body 130 which rotates in conjunction with opening and closing of the door 2b is provided in the high inner side between the door 2b and the door 2c so that outside air may not intrude from the clearance gap between doors. Condensation occurs when the outside surface temperature of the rotary partition body 130 is lower than the dew point temperature. Therefore, a heater (not shown) is provided inside the rotary partition body 130 to remove the dew condensation. I suppress it. The heater inside the rotary partition body 130 can change the current carrying ratio by duty control, and the rotary partition body 130 is based on values obtained from an outside air temperature sensor (not shown) and an outside air humidity sensor (not shown). The energization rate is adjusted so that the surface temperature of the high outer side of the () is not lower than the dew point temperature.

It is a figure which shows the flow of cold air blown from the 1st discharge port in the refrigerating chamber of 2nd Embodiment. Similar to the figure shown in FIG. 4, it is the J-J sectional drawing shown in FIG. 3 in the state which closed the door.

Like the door 2a of 1st Embodiment, the 1st door 2b and the 2nd door 2c are equipped with the foam heat insulating material 10a and the vacuum heat insulating material 26 inside. On the inner side of the refrigerating chamber 2, the door liner 121b and the door liner 122b are provided at both ends of the door 2b, and the door liner 121c and the door liner 122c are installed on the door 2c. It is installed at both ends of. If the width of the first door 2b is L8 and the width of the second door 2c is L9, these relations are [(L8) <(L9)]. In other words, the width of the second door 2c is wider than that of the first door 2b. The gasket 120 is provided in the clearance gap between the 1st door 2b, the 2nd door 2c, and the rotating partition body 130 so that the cold air of the refrigerator compartment 2 may not leak.

The refrigerator 1 of this embodiment is equipped with the 1st discharge port 101 in the area | region A on the side of the 1st door 2b. The shape of the 1st discharge port 101 is the same as that of the shape (refer FIG. 5A) shown by 1st Embodiment. The cold air discharged from the first discharge port 101 is discharged in a direction inclined at an angle θ1 in the counterclockwise rotational direction on the ground with respect to the center plane X, passes through the center plane X, and passes from the area A to the area B (first door 2b). From the rear region of the back door) to the rear region of the second door 2a). The cold air reaching the area B gradually decreases in speed, and reaches between the door liner 121c and the door liner 122c provided in the second door 2c. In addition, like the refrigerator 1 of the first embodiment illustrated in FIG. 2, the cold air discharged from the first discharge port 101 is interposed between the door pockets 32 provided in plural in the vertical direction of the second door 2c. The passage is adjusted to reach the second door 2c.

In the above, the structure of the refrigerator 1 which concerns on 2nd Embodiment and the flow of cold air discharged from the 1st discharge port 101 provided in the refrigerating chamber 2 were demonstrated, Next, the effect which the refrigerator 1 has is demonstrated. do.

In the refrigerator 1 of this embodiment, the cold air discharged from the 1st discharge port 101 provided in the area | region A passes through the center plane X, and the door liner 121c provided in the 2nd door 2c of the right side, and Reaching between the door liners 122c. Thereby, the refrigerator with high energy saving performance which reduced the invasion of the heat from the outside can be obtained, without excessively cooling the area | region C with low heat insulation performance. The reason will be described below with reference to FIG. 12.

It is a figure which shows an example of the flow of the conventional cold air in the refrigerator compartment provided with two doors. This is the same as the flow of cold air in the conventional refrigerator compartment in the case of having one door shown in FIG. 6C. The discharge port 106 and the cold air duct 11c provided with the discharge port 106 are provided on the center plane X, and the cold air is discharged from the discharge port 106 toward the front of the refrigerating chamber 2. Here, when the space E between the door liner 122b on the side of the first door 2b and the door liner 121c on the side of the second door 2c including the rotating partition body 130 is defined as the area E, The area E is located in the area A because the width of the second door 2c is wider than that of the first door 2b. The cold air discharged from the discharge port 106 reaches near the left end of the second door 2c while diffusing, and part of the cold air reaches the region E. FIG. In the region E, as in the region C (see FIG. 11) described above, the gasket 120, the first door 2b, the second door 2c, and the heat conduction from the surface of the rotating partition body 130 are high. Heat from the outside is easy to invade. Therefore, when cold air tends to reach the region E, the intrusion of heat from this portion tends to be large. In addition, when the rotational partition body 130 provided in the area E is cooled by cold air, the heater (not shown) in the rotational partition body 130 is omitted so that the surface temperature of the high outer side of the rotational partition body 130 does not fall below the dew point temperature. The heating amount of may be increased.

On the other hand, in the refrigerator 1 of this embodiment, since it is adjusted so that cold air may reach between the door liner 121c and the door liner 122c by the side of the 2nd door 2c of the refrigerating chamber 2, it is cold to the area E. Is getting harder to reach.

Therefore, according to the refrigerator 1 of 2nd Embodiment, compared with the conventional flow of cold air in the refrigerating chamber shown in FIG. 12, suppression of the invasion of the heat from the outside in the area | region E and the heater in a partition arrange | positioned in the area | region E Since the heating amount of can be suppressed, the refrigerator with high energy saving performance can be obtained.

In the refrigerator 1 of 2nd Embodiment shown in FIG. 11, the width L8 of the 1st door 2b arrange | positioned at the area | region A side is compared with the width L9 of the 2nd door 2c arrange | positioned at the area | region B side. Since it is narrow, the area E is contained in the area A. Since the 1st discharge port 101 is provided in this area | region A, since the cold air which passed through the center plane X flows to area | region B, it becomes difficult to reach cold area | region. That is, by providing the 1st discharge port 101 in the narrow door side, cooling of the area | region E can be suppressed and the refrigerator with high energy saving performance can be obtained.

In addition, similar to the refrigerator 1 of the first embodiment in which the refrigerating chamber is constituted by a single door, the cold air discharged from the first discharge port 101 is interposed between the door pockets 32 provided in plural in the vertical direction of the door 2c. Since it is adjusted so as to reach the door 2c through the passage (see FIG. 2), cold air blowing to the region E together with the region C is also suppressed, resulting in a refrigerator having high energy saving performance.

In FIG. 11, although the effect in the refrigerator 1 of 2nd Embodiment provided with the rotating partition body 130 was demonstrated, the door liner 121 provided in the 1st door 2b and the 2nd door 2c, respectively. If the area E is a refrigerator having a lower thermal insulation performance than the space between the door liner 122 and the door liner 122, a refrigerator having a high energy saving performance that suppresses the ingress of heat from the outside can be obtained by suppressing the blowing of cold air into the area E. .

(Third Embodiment)

Next, the refrigerator 1 of 3rd Embodiment is demonstrated with reference to FIG. 13 and FIG. The refrigerator 1 of 3rd Embodiment is a refrigerator which discharges cold air so that it may cross | intersect toward the front of the refrigerator compartment 2 from each discharge port provided in two cold air ducts. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

It is a schematic diagram of the front of the state which removed the door of the refrigerator compartment in the refrigerator of 3rd Embodiment. It is a figure which shows the flow of cold air blown from the 4th discharge port in the refrigerator of 3rd Embodiment. A cross section is the L-L cross section of FIG.

The door 2a provided in the front side of the refrigerator compartment 2 is the same as that of 1st Embodiment. Each discharge port 101, 102, 103 provided in the 1st refrigerator compartment duct 11 is arrange | positioned and comprised like 1st Embodiment. In addition to the second refrigerating chamber duct discharge port 110, the second refrigerating chamber duct 12 is provided with a fourth discharge port 111 and a fifth discharge port 112. In the refrigerator compartment 2 of 3rd Embodiment, the 1st discharge port 101 and the 2nd refrigerator compartment with which the 1st refrigerator compartment duct 11 was provided in the shelf space partitioned by the shelf 39a, 39b and the shelf 39c. The 4th discharge port 111 provided in the duct 12 is provided, and the 4th discharge port 111 is arrange | positioned at the lower right side of the 1st discharge port 101. FIG. Similarly, in the space partitioned by the shelves 39c and 39d, the second discharge port 102 provided in the first refrigerating chamber duct 11 and the fifth discharge port 112 provided in the second refrigerating chamber duct 12 are provided. The fifth discharge port 112 is disposed at the lower right side of the second discharge port 102.

On the other hand, since the effect which the 5th discharge port 112 has is equivalent to the 4th discharge port 111, the 4th discharge port 111 is demonstrated.

As shown in FIG. 13, the 4th discharge port 111 is located below the 1st discharge port 101, and as shown in FIG. 14, the right end of the 4th discharge port 111 is the center of the width direction of the refrigerating chamber 2. As shown in FIG. It is located to the right by L2d with respect to plane X. The cold air discharged from the first discharge port 101 is discharged to the right inclined front of the refrigerating chamber 2 like the refrigerator 1 of the first embodiment, passes over the center plane X, and reaches from the region A to the region B. It reaches between the door liner 121 and the door liner 122 installed in the door 2a.

On the other hand, the cold air discharged from the fourth discharge port 111 is discharged toward the front of the left inclination of the refrigerating chamber 2, passes over the center plane X, reaches from the region B to the region A, and the door liner of the door 2a ( 121, 122).

The cold air discharged from the first discharge port 101 and the fourth discharge port 111 is discharged to cross each other toward the front of the refrigerating chamber, but the fourth discharge port 111 is provided below the first discharge port 101. Therefore, when passing through the center plane X, the cold air discharged from the fourth discharge port 111 passes below the cold air discharged from the first discharge port 101.

That is, in the refrigerator 1 of 3rd Embodiment, since the installation height is provided so that the installation height may differ from the 1st discharge port 101 and the 4th discharge port 111 in the space partitioned by the same shelf, it discharged from each discharge port. The influence of cold air can be suppressed to pass through the center plane X, and a refrigerator with high energy saving performance can be obtained.

The reason for this is further described below. For example, when the first discharge port 101 and the fourth discharge port 104 are arranged and configured symmetrically, they are discharged to cross each other at the same height toward the front of the refrigerating chamber. The flows interfere with each other and the flow changes greatly.

On the other hand, as shown in FIG. 4, in the refrigerator of the first embodiment, the cold air from the first discharge port 101 is directed inclined forward, passes through the center plane X within the range of the shelf 39c, and is insulated. In consideration of not reaching the region C having low performance, cold air is blown to suppress the intrusion of heat from the wall surface or between the door 2a and the side wall surface. Therefore, the directivity of the discharged cold air becomes important in order to suppress the invasion of heat, but when it is influenced by the flow of other cold air, it is difficult to give the proper directivity to the cold air.

On the other hand, in the refrigerator 1 of this embodiment, by changing the installation height of the 1st discharge port 101 and the 4th discharge port 111, it is difficult to cancel the directivity of cold air, and it is the thing of the cold air discharged from a 4th discharge port. Since it is hard to be influenced, the directivity of the cold air discharged from the 1st discharge port 101 is stable, and it can be set as the cold air flow which can obtain a high energy saving performance comparatively easily.

On the other hand, in the refrigerator 1 of this embodiment, it is hard to be influenced by each cold air by changing the installation height of the 1st discharge port 101 and the 4th discharge port 111, For example, arrange | positioning at the same height Thus, by configuring the air to be discharged upward from the first discharge port 101 and downward from the fourth discharge port 111, it may be difficult to be affected by the respective cold air.

In addition, like the refrigerator 1 of this embodiment, in the refrigerator which controls discharge of cold air from each of the 1st discharge port 101 and the 4th discharge port 111 with another damper, respectively by control of a damper, It is also conceivable to stabilize the directivity of the cold air by shifting the cold air discharged from the discharge port of the gas in time. That is, by not simultaneously opening the first refrigerator compartment damper 50a for controlling the blowing to the first discharge port 101 and the damper of the second refrigerator compartment damper 50b for controlling the blowing of the fourth discharge port 111, The desired flow of cold air can be obtained relatively easily without being influenced by the flow of cold air discharged from another discharge port.

(Fourth Embodiment)

Next, the refrigerator 1 of 4th Embodiment is demonstrated with reference to FIG. The refrigerator 1 of 4th Embodiment is a refrigerator in which the 1st discharge port 101b which discharges cold air in front of a right inclination is provided near the back left end of the refrigerating chamber 2. In addition, about the structure similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

It is a figure which shows the flow of cold air blown from the 1st discharge port in the refrigerating chamber of 4th Embodiment. As shown in FIG. 4, it is J-J sectional drawing of FIG. 3 with a door closed.

Although the refrigerator 1 of this embodiment is equipped with two cold air ducts, the 1st refrigerator compartment duct 11 and the 2nd refrigerator compartment duct 12 are isolate | separated. Like the refrigerator 1 of 1st Embodiment shown in FIG. 3, the 2nd refrigerator compartment duct discharge port 110 of the 2nd refrigerator compartment duct 12 is provided above the upper part of the shelf 39a of the uppermost stage, and is 1 The discharge port is not provided in the space partitioned by the shelf provided with the discharge port 101b.

The 1st discharge port 101b which discharges cold air in front of a right tilt direction, and the 1st refrigerator compartment duct 11 provided with the 1st discharge port 101b are arrange | positioned near the back left end of the refrigerating chamber 2. The second refrigerating compartment duct 12 is disposed near the rear right end of the refrigerating compartment 2. However, the distance L10a from the left side to the left end of the first refrigerator compartment duct 11 and the second refrigerator compartment duct so that the side wall surface is not directly cooled from the first refrigerator compartment duct 11 and the second refrigerator compartment duct 12. The distance L10b to the right end of (12) is set to 10 mm or more (L10a = L10b = 20mm in this embodiment).

The distance between the left end of the first discharge port 101b and the center plane X is L2e (L2e = 26Omm in this embodiment) which is larger than L2 (= 80 mm) of the first embodiment. The cold air discharged from the first discharge port 101b flows inclined θ1b in the counterclockwise rotational direction (from left to right) on the ground with respect to the center plane X, and, as in the first embodiment, within the range of the shelf 39c. It passes through the center surface X, and reaches between the door liners 121 and 122. As shown in FIG.

Here, FIG. 4 of 1st Embodiment is compared with FIG. 15 of this Embodiment. Since the 1st discharge port 101b of FIG. 15 is provided in the left side compared with the 1st discharge port 101 of FIG. 4, the door liner 121, 122 passes the center plane X within the range of the shelf 39c. It is understood that the discharge angle θ1b of FIG. 15 of the cold air at the time of adjusting so as to reach the angle is larger than the angle θ1 of FIG. 4. As described above, when the discharge angle θ1b is increased, the distance L6b until the cool air discharged from the first discharge port 101b reaches the door 2a becomes long, so that the door 2a becomes difficult to cool.

In addition, when discharged vertically from the position of the 1st discharge port 101b of FIG. 15 toward the front of the refrigerating chamber 2, since it flows to the area | region A without passing through the center plane X, the thing in the area | region B The area A side or the left side surface of the door 2a is excessively cooled until it cools down. On the other hand, by blowing air through the central plane X, cold air flows in both the region A and the region B, so that biased cooling can be suppressed.

Therefore, when the 1st discharge port 101b is arrange | positioned near the side surface, the cold air discharged from the 1st discharge port 101b passes through the center surface X within the range of the shelf 39c, and the door liners 121 and 122 are carried out. The effect of suppressing the invasion of heat by reaching between) becomes larger.

(Fifth Embodiment)

Next, the refrigerator 1 of 5th Embodiment is demonstrated with reference to FIG. 16 and FIG. The refrigerator 1 of 5th Embodiment is a refrigerator of the so-called side-by-side type which arrange | positioned the refrigeration temperature room and the refrigeration temperature room adjacent to the left and right. In addition, about the member similar to 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

It is a front view of the refrigerator which concerns on 5th embodiment of this invention.

In the refrigerator 1 of 5th Embodiment, the refrigerating temperature chamber 60 is arrange | positioned at the left side, the refrigerating chamber 2 at the upper right side, and the vegetable chamber 6 is arrange | positioned at the lower part. The refrigerator compartment 2 and the vegetable compartment 6 are rotatably axially rotatably supported by the hinge 37a when viewed from the front, respectively, and the refrigerator compartment door 2a and the vegetable chamber 6a, which rotate around the left side when viewed from the upper surface, respectively. Equipped with. The refrigeration temperature zone chamber 60 has a refrigeration temperature zone door 60a which is rotatably rotatable by the hinge 37b when viewed from the front side, and rotates around the right side when viewed from the upper surface.

FIG. 17 is a cross-sectional view taken along line M-M in FIG. 16, illustrating a flow of cold air blown from the first discharge port in the refrigerating chamber of the fifth embodiment. FIG.

In the figure, the center plane X of the width direction is shown with reference to the storage space in the refrigerating chamber 2, respectively. Regions A and B are inverted from the first embodiment, and the region A is a storage space on the right side of the center plane X, and the region B is a storage space on the left side of the center plane X.

The refrigerating chamber 2 and the refrigerating temperature chamber 60 are spaced apart by the heat insulation partition wall 28a. In the refrigerator compartment duct structural member 80 of the refrigerator 1 of this embodiment, the 1st refrigerator compartment duct 11 provided with the 1st discharge port 101 is arrange | positioned at the right side of the 2nd refrigerator compartment duct 12. As shown in FIG. The 2nd refrigerator compartment duct discharge port 110 is not provided in the same shelf space as the 1st discharge port 101c like the refrigerator 1 of 1st Embodiment.

The 1st discharge port 101c is provided in the area | region A, and the right end of the 1st discharge port 101c is located in L2 right side rather than the center plane X. As shown in FIG. The cold air discharged from the first discharge port 101 is discharged toward the front of the left inclination, passes through the region C, and reaches between the door liner 121 and the door liner 122 of the refrigerating chamber door 2a.

Since the air is discharged from the first discharge port 101c to the left inclined front side, the cold air that reaches the refrigerating chamber door 2a from the first discharge port 101c flows along the inner wall surface of the refrigerating chamber door 2a, and then the door liner ( 121) it is turned in the depth direction and flows to the left side. Therefore, compared with the right side, the left side is a flow of cold air which is easy to cool.

Here, the left side surface of the refrigerating compartment 2 of this embodiment is the heat insulation partition wall 28a which insulates the refrigerating compartment 2 and the refrigerating temperature chamber 60, and the right side insulates the refrigerating compartment 2 and the outside of a refrigerator. It is an insulation box 10 to be. Even if the heat insulation partition wall 28a which divides between storage rooms is cooled, the quantity of heat cooled in the whole refrigerator 1 does not change. On the other hand, when the wall surface of the heat insulation box 10 which is insulated with the outside outside is cooled, the temperature difference in the inside of the inside of the inside of a high outside becomes large, and the invasion of heat from the outside outside becomes large, resulting in the fall of energy saving performance. .

Therefore, in the refrigerator 1 equipped with the freezing temperature chamber 60 which is a storage chamber on the left side of the refrigerating chamber 2, the 1st discharge port 101c is provided in the right side rather than the center plane X, and cold air is discharged to the left inclination front. By doing so, it becomes a refrigerator with high energy saving performance.

In addition, in the refrigerator 1 of this embodiment, the freezer compartment damper 52 is provided so that the refrigerator compartment 2 can be cooled independently. In such a refrigerator 1, the cooling effect is blown to the heat insulation partition wall 28a side, and the improvement effect of energy saving performance by restraining the movement of the heat in a refrigerator can also be obtained. The reason will be described below.

In the refrigerator cooled by the refrigerating cycle, when the cold air is cooled by the cooler 7, it is known that the higher the temperature of the cooler 7 is, the higher the cooling efficiency is. In the refrigerator 1 capable of cooling the refrigerating compartment 2 alone, the storage in the refrigerating compartment 2 can be cooled by using a colder at a higher temperature than when the refrigerating temperature chamber 60 is cooled, thereby increasing the cooling efficiency. have. Therefore, in the refrigerator 1, the movement of heat from the refrigerating chamber 2 to the freezing temperature chamber 60 reduces the energy saving performance due to the difference in the cooling efficiency between the refrigerating chamber 2 and the freezing temperature chamber 60. Cause.

Here, in the heat insulation partition wall 28a, heat moves from the refrigerating chamber 2 to the refrigerating temperature chamber 60 by the temperature difference of the refrigerating chamber 2 and the freezing temperature chamber 60. On the other hand, by cooling the heat insulation partition wall 28a from the refrigerating compartment 2 side, the temperature difference in the refrigerating compartment 2 side of the heat insulation partition wall 28a and the refrigeration temperature chamber 60 side becomes small. That is, the movement of heat from the refrigerating chamber 2 through the heat insulation partition wall 28a to the freezing temperature zone chamber 60 is suppressed.

Therefore, in the refrigerator 1 which can cool the refrigerating compartment 2 independently, the cold air is discharged to the left inclination front side, and cold air is blown to the heat insulation partition wall 28a side, and the refrigerating temperature chamber ( The movement of heat to 60) is also suppressed, resulting in a refrigerator having higher energy saving performance.

On the other hand, since the present effect is obtained by a refrigerator capable of cooling the refrigerator compartment 2 alone or preferentially, for example, instead of the freezer compartment damper 52, for example, a second internal fan is mainly provided to cool the refrigerator compartment 2. The same effect can be achieved with a refrigerator.
