Description

  The present invention relates to a refrigerator including a panel portion in which a refrigerator compartment air passage for sending cold air to the refrigerator compartment is formed, and the refrigerator compartment air passage is branched.

  For example, a refrigerator is provided with a refrigerator compartment (main refrigerator compartment) in which stored items can be taken in and out by opening a door. For example, the refrigerator compartment that opens and closes the door is often provided at the top of the refrigerator. In order to cool the entire inside of the refrigerator compartment by blowing out cold air from above the refrigerator compartment, the generated cold air may be sent to the upper portion of the refrigerator compartment through the refrigerator compartment ventilation path.

  Patent Document 1 describes an example of a refrigerator that sends cold air generated below such a refrigerator upward and blows it out of the refrigerator compartment. Specifically, Patent Document 1 describes a refrigerator in which an internal blower fan 19 that sends air (cold air) heat-exchanged by a cooler 16 is provided and cool air is directed to the upper refrigerating chamber 2 by a refrigerating chamber air duct 35. (Patent Document 1: Paragraphs [0019] to [0021], see FIG. 2).

JP 2007-147112 A

  For example, the refrigerator compartment provided in the upper part of the refrigerator often has the largest internal volume among the storage rooms provided in the refrigerator. And from a viewpoint of preventing large unevenness in the temperature distribution in the refrigerator compartment, an outlet for blowing cold air out of the refrigerator compartment may be provided at a position separated in the left-right direction of the refrigerator compartment.

  In order to blow out the cold air from the respective outlets at positions separated in the left-right direction, the refrigerator compartment ventilation path for sending the cold air may be branched above the refrigerator compartment. And each blower outlet is connected to the branched branch ventilation path, and cold air is blown off from each blower outlet toward a refrigerator compartment.

  Here, there may be a difference in the flow rate of the cold air flowing through the branch ventilation path due to factors such as the angle at which the cold air blows up. If it does so, a difference will arise in the quantity of the cold air which blows off from the blower outlet provided in the position left-right direction (a quantity will be biased), and it may become difficult to make uniform the temperature distribution of a refrigerator compartment.

  Conventionally, when adjusting the flow rate of cold air flowing through a branched air passage in a refrigerator, a step (bank) is provided on the stairs on the wall surface of one of the air flow passages (the cold room air flow passage where the flow rate of the cold air is to be reduced). The flow velocity is intentionally reduced (squeezed). However, such a flow rate adjustment has a problem of slowing down the momentum of the cold air (disturbing the flow of the cold air), causing waste to stop a part of the blown-up cold air and not being efficient. Moreover, if the step of the refrigeration room ventilation path to be provided is determined (the shape of the design ventilation path including the step is determined), the flow rate of the cold air flowing in the branched ventilation path becomes fixed, and each branch ventilation There is also a problem that it is difficult to flexibly adjust the flow rate of the cool air after the road.

  Further, according to Patent Document 1, although the cool air is blown toward the refrigerating room, the amount of the cool air blown to the refrigerating room and the vegetable room is controlled. However, there is no description about adjusting the flow rate of each of the branched refrigeration chamber air passages through the cold air blown up toward the refrigeration chamber, and the efficiency of the cooling air blowing to each of the cold branch air passages is not described. The problem and the problem of flexibility in adjusting the flow rate to each branched ventilation path cannot be solved.

  In view of the above problems, the present invention efficiently adjusts the flow of cold air to the branched refrigeration chamber ventilation paths while allowing flexibility in adjusting the flow rate of the cold air to each of the branched refrigeration room ventilation paths. Realize that.

  In order to achieve the above object, a refrigerator according to claim 1 generates cold air, cools the cold air to be sent out, a refrigerating room, and a refrigerating room that blows out the refrigerating room from a plurality of outlets provided in the refrigerating room. A panel part that is attached to one surface of the refrigeration room, including a branched ventilation path that branches the ventilation path and the refrigeration room ventilation path, and a branch part that is attached to the panel part and branched to the branch part of the refrigeration room ventilation path. In order to adjust the flow rate of the cold air to the branch ventilation path, an adjustment plate for adjusting the flow of the cold air is included.

  According to this configuration, the refrigerator includes a refrigerating room ventilation path that blows out from a plurality of outlets provided in the refrigerating room to the refrigerating room and a branch ventilation path that branches the refrigerating room ventilation path, and is a panel that is attached to one surface of the refrigerating room And an adjustment plate for adjusting the flow of the cold air in order to adjust the flow rate of the cold air to each branched air passage. Thereby, the flow rate of the cold air to each branch ventilation path can be adjusted efficiently without easing the momentum of the cold air as in the prior art. Since cool air can be sent efficiently in this way, for example, power consumption in a portion (for example, a fan) that sends out cool air in the cooling unit can be reduced, and power consumption of the refrigerator can be reduced. Also, by changing the shape of the adjustment plate that is retrofitted (attached) to the panel, the flow rate of cool air to each branch ventilation path can be adjusted afterwards, and the flow rate of cold air to each branch ventilation path can be adjusted flexibly. It can be carried out.

  Further, in the refrigerator configured as described above, when the return port is provided on the left side of the center of the refrigerator compartment, the adjustment plate is formed so as to increase the flow rate of the cold air in the second branch ventilation path rather than the first branch ventilation path, When the return port is provided on the right side of the center of the refrigerator compartment, the adjustment plate may be formed so as to increase the flow rate of the cold air in the first branch ventilation path rather than the second branch ventilation path.

  With this configuration, it is possible to increase the amount of cold air blown from the air outlet provided on the opposite side in the left-right direction with respect to the return port, rather than the air outlet provided on the same side in the left-right direction as the return port. Thereby, the component of the cold air which flows diagonally downward toward the return port from the blower outlet increases. Therefore, it is possible to intentionally lengthen the path of the cold air from the blowout port to the return port, thereby efficiently cooling the refrigerator compartment. Therefore, driving of the cooling unit can be reduced, and power saving of the refrigerator can be achieved.

  In the refrigerator configured as described above, the adjustment plate may be formed so that the amount of cold air blown out from the right air outlet and the amount of cold air blown out from the left air outlet are equal.

  With this configuration, it is possible to equalize the cold air blown out from the respective outlets (the right outlet and the left outlet) separated in the left-right direction in the refrigerator compartment. Thereby, the inside of a refrigerator compartment can be cooled uniformly.

  Moreover, in the refrigerator of the said structure, you may make it the thickness of an adjustment plate thinner than the depth of a refrigerator compartment ventilation path.

  With this configuration, it is possible to adjust the flow rate of the cold air to each branch ventilation path by adjusting the thinness of the adjustment plate. In other words, by adjusting the thinness of the adjustment plate, the rectification level of the cold air by the adjustment plate can be adjusted. Therefore, it is possible to flexibly adjust the flow rate of cool air to each branch ventilation path.

  Moreover, in the refrigerator of the said structure, you may make it round the corner part which protrudes toward the cold air sent from a cooling part among the corner parts of an adjustment plate.

  With this configuration, the cool air can flow (can be guided) to each branch ventilation path without causing a disturbance in the flow of the cool air.

  According to the refrigerator of the present invention, it is possible to adjust the flow rate of the cool air that flows efficiently to each branch ventilation path without reducing the momentum of the cool air as in the past. Further, by changing the shape of the adjusting plate, the flow rate to each branch ventilation path can be adjusted afterwards, and the flow rate of cold air to each branch ventilation path can be adjusted flexibly.

(Generation and circulation of cold air)
An example of the production | generation and circulation of the cool air in the refrigerator 100 which concerns on embodiment is demonstrated using FIGS. FIG. 4 is a cold air circuit diagram showing an example of the flow of cold air in the refrigerator 100.

  First, a cooler 71 and a compressor 72 connected to the cooler 71 are provided below the rear surface of the refrigerator 100. A condenser and an expander (both not shown) are connected to the compressor 72. A refrigerant such as isobutane is circulated by driving the compressor 72 to operate the refrigeration cycle. Thereby, cold air is generated by heat exchange in the cooler 71 on the low temperature side of the refrigeration cycle. The compressor 72 is driven when the indoor temperature of the refrigerator compartment 2 or the upper freezer compartment 4 or the lower freezer compartment 5 rises above the upper limit temperature on the high temperature side with respect to the set temperature, and when the lower limit temperature on the low temperature side with respect to the set temperature is reached. Stopped.

  A first ventilation path 73 is provided behind the upper freezer compartment 4 and the lower freezer compartment 5. A cooler 71 is disposed in the first ventilation path 73. In addition, a refrigerator compartment ventilation path 90 connected to the first ventilation path 73 is provided behind the refrigerator compartment 2. The generated cold air is supplied to each chamber through the first ventilation path 73 and the refrigerator compartment ventilation path 90.

  A first blower 75 is disposed in the first ventilation path 73. The cold air generated by the cooler 71 is sent out by the first blower 75. For example, the cold air sent out by the first blower 75 is supplied to the ice making room 3, the upper freezer room 4, and the lower freezer room 5 through the first ventilation path.

  The first ventilation path 73 is connected to an ice making chamber outlet 81 provided on the back surface of the ice making chamber 3 and an upper freezer compartment outlet 82 (see FIG. 3). The cool air generated by the cooler 71 is sent up to the ice making chamber 3 by raising the first ventilation path 73 as indicated by an arrow A by driving the first blower 75. Further, the cold air generated by the cooler 71 rises through the first ventilation path 73 as shown by the arrow B (see FIG. 3) by driving the first blower 75 and is sent out to the upper freezer compartment 4. Thereby, the ice making room 3 and the upper freezer room 4 are cooled.

  Then, a lower freezing room 5 is connected to the ice making room 3 and the upper freezing room 4. The cold air that has passed through the ice making chamber 3 and the upper freezing chamber 4 also flows into the lower freezing chamber 5. Thereby, in addition to the ice making chamber 3 and the upper freezer compartment 4, the lower freezer compartment 5 is also cooled. A return ventilation path 76 (see FIG. 2) that guides air and returns cool air to the cooler 71 is provided in the lower rear part of the lower freezer compartment 5. Then, the cool air returns to the cooler 71 through the return ventilation path 76.

  A second blower 77 is disposed in the refrigerator compartment ventilation path 90. The cold air generated by the cooler 71 is also sent out by the second blower 77. For example, the cold air sent out by the second blower 77 is supplied to the refrigerator compartment 2, the chilled compartment 1, and the vegetable compartment 6 via the refrigerator compartment ventilation path 90.

  The upper part of the first ventilation path 73 is connected to the refrigerator compartment ventilation path 90. A refrigeration room damper 78 is provided between the first ventilation path 73 and the refrigeration room ventilation path 90. The cold air in the direction of the refrigerating room ventilation path 90 at the upper part of the first ventilation path 73 flows through the refrigerating room ventilation path 90 as shown by an arrow C (see FIG. 3) through the refrigerating room damper 78 by driving the second blower 77. . Further, the refrigerator compartment ventilation path 90 is connected to a plurality of refrigerator compartment outlets 83 on the back side of the refrigerator compartment 2. Thereby, the cold air flowing through the refrigerating room ventilation path 90 is blown into the refrigerating room 2 (in FIG. 3, an example of the refrigerating room ventilation path 90 is shown by a broken line, details will be described later).

  Further, the refrigerator compartment ventilation path 90 is connected to a rear outlet 80 provided on the rear side of the chilled chamber 1. Thereby, the cold air flowing through the refrigerator compartment ventilation path 90 is blown out from the rear of the chilled chamber 1 as indicated by an arrow D (see FIG. 3).

  A return port 84 is provided at the lower back of the refrigerator compartment 2 to collect the cold air below the refrigerator compartment 2 and send it out toward the vegetable compartment 6. The return port 84 is connected to the vegetable compartment 6 by a vegetable compartment ventilation path 79 (see FIG. 3). Thus, the cold air led to the refrigerator compartment ventilation path 90 flows through the refrigerator compartment 2 and the chilled compartment 1 and then flows into the vegetable compartment 6. The cold air that has flowed into the vegetable compartment 6 flows through the vegetable compartment 6 and returns to the cooler 71 via the ventilation path 76. When the refrigerator compartment 2, the chilled compartment 1, and the vegetable compartment 6 are cooled and reach a set temperature, the refrigerator compartment damper 78 is closed.

  In the refrigerator 100 of the embodiment, the ice making room 3, the upper freezer room 4, and the refrigerating room 2 are arranged in parallel in a cold air circuit (see FIG. 4). Further, the ice making room 3 and the upper freezer room 4 are arranged in series with the lower freezer room 5. The vegetable compartment 6 is arranged in series with the refrigerator compartment 2. The cooler 71, the compressor 72, the first blower 75, the second blower 77, the first ventilation path 73, and the refrigerating room ventilation path 90 generate cold air and sends the cold air to the refrigerating room 2 and the chilled room 1. Function as.

(Refrigerator room ventilation path 90)
Next, the panel part 9 provided in the back | inner side of the refrigerator compartment 2 and the refrigerator compartment ventilation path 90 contained in the panel part 9 are demonstrated using FIG.2, FIG.3, FIG.5, FIG.6. FIG. 5 is an explanatory diagram showing an example of the front side of the panel unit 9. FIG. 6 is an explanatory view showing an example of the back side of the panel unit 9.

  A refrigerator compartment ventilation path 90 is provided in the panel portion 9 provided in the back of the refrigerator compartment 2. As shown in FIG. 2, the main body of the refrigerator 100 is filled with a foaming heat insulating material (for example, urethane foam heat insulating material) between the outer cover 100a and the inner box 100b. The inner box 100b has a flat plate shape with respect to the vertical direction.

  And the panel part 9 shown in FIG. 5, FIG. 6 is attached to the front back side of the refrigerator compartment 2. As shown in FIG. In other words, the panel unit 9 is attached to the back side of the refrigerator compartment 2 so as to cover the inner box 100b on the back side of the refrigerator compartment 2. FIG. 5 is a view of the panel portion 9 as viewed from the front, and the panel portion 9 includes a panel plate 9a of a resin molded product (for example, PP, PS, ABS, etc.). Further, as shown in FIG. 6, a foamed resin 9b (for example, polystyrene foam) is attached to the back side of the panel plate 9a. Thus, the panel unit 9 is a combination of the panel panel 9a on the front surface and the foamed resin 9b on the back surface.

  And the refrigerator compartment ventilation path 90 is provided by denting the foamed resin 9b. In other words, a groove is provided in the foamed resin 9b on the back side of the panel portion 9, and the groove portion is used as the refrigerator compartment ventilation path 90. In FIG. 5, the refrigerator compartment ventilation path 90 (invisible refrigerator compartment ventilation path 90 in FIG. 5) provided on the back surface of the panel portion 9 is illustrated by a broken line.

  The panel unit 9 is provided with four refrigerator compartment outlets 83. A left outlet 83L and a right outlet 8 are provided further above the four refrigerator compartment outlets 83. By providing holes in the panel plate 9a and the foamed resin 9b behind the panel plate 9a, four refrigerator compartment outlets 83, a left outlet 83L, and a right outlet 83R are provided. Note that a left air outlet 83L and a right air outlet 83R may be provided further above the panel portion 9, and the branch ventilation paths 91 and 92 may be connected (the left air outlet 83L and the right air outlet 83R are provided outside the panel portion 9). May be) Further, another air outlet may be provided.

  The refrigerator compartment ventilation path 90 formed by providing a groove in the foamed resin 9b on the back of the panel plate 9a extends from the lower part of the panel part 9 to the upper right side as viewed from the front (see FIG. 5; upper left side when viewed from the rear side). Accordingly, the cold air sent from the second blower 77 flows along the refrigerator compartment ventilation path 90 in the right obliquely upward direction when viewed from the front (the obliquely upward direction when viewed from the back).

  And the angle of the refrigerator compartment ventilation path 90 changes, and in the center part of the panel part 9, the refrigerator compartment ventilation path 90 is extended in an up-down direction. Accordingly, the cool air sent from the second blower 77 flows along the refrigerator compartment ventilation path 90 in the right obliquely upward direction when viewed from the front (left obliquely upward direction when viewed from the back) and then flows upward. The refrigerator compartment ventilation path 90 is provided with four refrigerator compartment outlets 83 at positions extending in the vertical direction.

  Furthermore, the refrigerator compartment ventilation path 90 is branched at the upper part of the panel part 9. For convenience, the branched refrigerator compartment air passage 90 on the left side when viewed from the front (right side when viewed from the back, see FIGS. 6 and 7) is referred to as a “first branch air passage 91”. Further, the branched refrigerating room ventilation path 90 on the right side when viewed from the front (left side when viewed from the back, see FIGS. 6 and 7) is referred to as a “second branch ventilation path 92”. The cold air passing through the first branch ventilation path 91 is blown out from the left outlet 83L. Further, the cold air passing through the second branch ventilation path 92 is blown out from the right outlet 83R. Thereby, cold air can be blown out from the position left and right in the upper part of the refrigerator compartment 2.

(Cooling air flow adjustment in each branch ventilation path)
Next, the flow rate adjustment of the cold air in each branch ventilation path will be described with reference to FIGS. FIG. 7 is an explanatory view showing an example of the back side of the panel unit 9 provided with the adjusting plate 10.

  First, as shown in FIG. 7, on the back surface of the panel portion 9 of the present embodiment, the flow rate of the cold air to each branch ventilation path between the first branch ventilation path 91 and the second branch ventilation path 92 (branch position). An adjustment plate 10 for adjusting the angle is attached. In FIG. 7, the adjustment plate 10 is shown by hatching.

  For example, the adjusting plate 10 is a resin having a heat insulation property (for example, styrene foam). The adjusting plate 10 is retrofitted to the back surface of the panel portion 9. For example, the adjustment plate 10 is attached with an adhesive or the like. A hole is provided in the refrigerator compartment ventilation path 90, and a protrusion is also provided on the adjustment plate 10 (a protrusion may be provided in the refrigerator compartment ventilation path 90, and the adjustment plate 10 may be a hole), and the protrusion and the hole are fitted together. Thus, the adjustment plate 10 may be attached to the back surface of the panel unit 9 at an appropriate position.

  Here, the flow of cold air when the adjusting plate 10 is not provided will be described with reference to FIG. As shown in FIG. 6, in the refrigerator 100 of the present embodiment, the cool air is not taken into consideration in consideration of the installation position of the second blower 77 (cooling unit), the position of the first ventilation path 73, the position of the refrigerator compartment outlet 83, and the like. It is blown up to the left diagonally upward direction when viewed from the back of the refrigerator compartment 2 (see the diagonally upward direction when viewed from the front, see FIG. 5 etc.) (in FIG. 6, the direction of the cold air is shown by the white arrow).

  Then, the component of the cold air flowing through the refrigerator compartment air passage 90 tends to be directed upward in the left direction as viewed from the back (upward direction in the right direction as viewed from the front). In other words, it becomes easier for the cold air to flow in the upper left direction when viewed from the back. Therefore, of the first branch ventilation path 91 and the second branch ventilation path 92, the second branch ventilation path 92 that flows cold air in the upper left oblique direction (when viewed from the front, right oblique upward direction) as viewed from the back is the first. The flow rate of cool air is larger than that of the branch ventilation path 91 (in FIG. 6, the fact that the second branch ventilation path 92 has a larger flow rate of cold air is indicated by the difference in size of the white arrow).

  When the flow rate of cool air in the second branch ventilation path 92 increases, the amount of cool air blown out from the right outlet 83R connected (provided) to the second branch ventilation path 92 blows out from the left outlet 83L. More than the amount of cold air that will be done. If it does so, it may become difficult to cool the room | chamber interior of the refrigerator compartment 2 equally. Therefore, in the refrigerator 100 of the present embodiment, as shown in FIG. 7, an adjustment plate 10 that adjusts the flow rate of cool air to each branch ventilation path is provided.

  Thus, by providing the adjusting plate 10 so as to protrude toward the branch position of the refrigerator compartment air passage 90, the flow of the cold air at the branch portion is adjusted, and the first branch air passage 91 and the second branch air passage 92 are arranged. The flow rate of cold air can be adjusted. Further, the adjustment plate 10 can branch the cool air sent to the refrigerating room ventilation path 90 into the first branch ventilation path 91 and the second branch ventilation path 92 at a desired flow rate.

  For example, the cold air generated by the cooler 71 is sent out from the lower side to the upper side by the first blower 75 or the second blower 77, and the refrigerator compartment ventilation path 90 is connected to the first branch ventilation path 91 and the second branch ventilation. When branching to the path 92, the amount of cold air blown from the right outlet 83R connected to the second branch ventilation path 92 and the amount of cold air blown from the left outlet 83L connected to the first branch ventilation path 91 are reduced. The adjustment plate 10 may be formed so that the amount is uniform. Thereby, the amount of cold air blown out from the right outlet 83R and the amount of cold air blown out from the left outlet 83L can be made uniform, and the refrigerator compartment 2 can be cooled evenly.

  In the present embodiment, the cold air is blown up in the upper left direction as viewed from the back (upward direction in the right direction when viewed from the front). Therefore, when the adjustment plate 10 is not provided, a component toward the second branch ventilation path 92 (the right outlet 83R) increases. Therefore, as shown in FIG. 7, in order to equalize the amount of cold air blown out from the left outlet 83L and the amount of cold air blown out from the right outlet 83R toward the upper side of the refrigerator compartment ventilation path 90, the refrigerator compartment To narrow the cold air inlet 92a from the ventilation path 90 to the second branch ventilation path 92 side, and to widen the cold air inlet 91a from the refrigerator compartment ventilation path 90 to the first branch ventilation path 91 side. become. In other words, of the total width of the refrigerator compartment ventilation path 90, the first branch from the refrigerator compartment ventilation path 90 is larger than the ratio of the width W2 of the cold air inlet 92a from the refrigerator compartment ventilation path 90 to the second branch ventilation path 92 side. The ratio of the width W1 of the cold air inlet 91a toward the ventilation path 91 is increased (see FIG. 7).

  There are various shapes of the adjusting plate 10 in which the amount of cold air blown from the left outlet 83L and the amount of cold air blown from the right outlet 83R are uniform. For example, a plurality of adjustment plates 10 having different shapes are created on a trial basis, and the adjustment plates 10 are sequentially replaced, so that the amount of cold air blown out from the left outlet 83L and the cold air blown out from the right outlet 83R are experimentally determined. You may search for the shape of the adjustment board 10 in which the quantity of is equal. Further, from the left air outlet 83L by computer simulation using data of the direction in which the cold air flows, the shape of the refrigerating room ventilation path 90, and the shape of the first branch ventilation path 91 and the second branch ventilation path 92. You may search for the shape of the adjustment board 10 from which the quantity of the cold air blown off and the quantity of the cold air blown off from the right side outlet 83R become equal.

  In the refrigerator compartment 2 of the present embodiment, a return port 84 for returning the cool air toward the cooling unit (cooler 71 etc.) is provided on the right side of the refrigerator compartment 2 below the refrigerator compartment 2. Therefore, the cold air generated by the cooler 71 is sent from the lower side to the upper side by the first blower 75 and the second blower 77, and the refrigerator compartment air passage 90 is connected to the first branch air passage 91 and the second branch air passage. When branching to the path 92, the adjustment plate 10 may form the adjustment plate 10 so that the flow rate of the cold air in the first branch ventilation path 91 is larger than that of the second branch ventilation path 92. Thereby, the quantity of the cold air which blows off from the left blower outlet 83L and flows right diagonally downward toward the return outlet 84 can be increased, the movement distance of cold air can be earned, and the refrigerator compartment 2 can be cooled efficiently.

  In the present embodiment, as described above, the cold air is blown up in the upper left direction as viewed from the back (upward direction in the right direction when viewed from the front). Therefore, when the adjustment plate 10 is not provided, a component toward the second branch ventilation path 92 increases. Therefore, as shown in FIG. 7, the flow rate of cold air to the first branch ventilation passage 91 (the amount of cold air blown from the left outlet 83L) is changed to the flow rate of cold air to the second branch ventilation passage 92 (right outlet 83R). The amount of cool air blown out from the refrigerator compartment vent passage 90 to the second branch vent passage 92 is further increased than when equalizing the amount of cool air from the left outlet 83L and the right outlet 83R. The cold air inlet 92a to the side is narrowed, and the cold air inlet 91a from the refrigerator compartment air passage 90 to the first branch air passage 91 is widened. In other words, of the total width of the refrigerator compartment ventilation path 90, the first branch from the refrigerator compartment ventilation path 90 is larger than the ratio of the width W2 of the cold air inlet 92a from the refrigerator compartment ventilation path 90 to the second branch ventilation path 92 side. The ratio of the width W1 of the cold air inlet 91a toward the ventilation path 91 is made larger than when the amount of cold air from the left outlet 83L and the right outlet 83R is made equal (see FIG. 7).

  Here, the shape of the adjusting plate 10 in which the amount of cool air blown from the left outlet 83L is larger than that of the right outlet 83R is various. For example, by preparing a plurality of adjustment plates 10 having different shapes and replacing the adjustment plates 10 sequentially, the amount of cold air blown out from the left outlet 83L is experimentally increased (largely) from the right outlet 83R. The shape of the adjusting plate 10 may be searched for. Further, from the left air outlet 83L by computer simulation using data of the direction in which the cold air flows, the shape of the refrigerating room ventilation path 90, and the shape of the first branch ventilation path 91 and the second branch ventilation path 92. The shape of the adjusting plate 10 in which the amount of cool air blown out increases (becomes larger) than the right outlet 83R may be searched for.

  Note that if the amount of cool air blown out from the right outlet 83R is too small, the right side of the refrigerator compartment 2 may become difficult to cool. Therefore, the amount of cold air blown out from the right outlet 83R exceeds the predetermined minimum flow rate, and the amount of cold air blown out from the right outlet 83R and blown out from the left outlet 83L. It is preferable to define the shape of the adjusting plate 10 that is larger than the right outlet 83R.

  In the refrigerating room 2 of the present embodiment, an example is provided below the refrigerating room 2 with a return port 84 for returning the cool air toward the cooling unit (cooler 71 etc.) on the right side of the center of the refrigerating room 2. However, the return port 84 is sometimes provided on the left side of the center of the refrigerator compartment 2. In this case, the cold air generated by the cooler 71 is sent out from the lower side to the upper side by the first blower 75 and the second blower 77, and the refrigerating room ventilation path 90 is connected to the first branch ventilation path 91 and the second branch. When branching to the ventilation path 92, the adjustment plate 10 causes the adjustment plate 10 to increase the flow rate of the cold air in the second branch ventilation path 92 (right outlet 83R) more than that of the first branch ventilation path 91 (left outlet 83L). It may be formed (or the adjusting plate 10 may be removed).

  As described above, the adjustment plate 10 adjusts the flow direction of the cold air flowing in the first branch ventilation path 91 and the second branch ventilation path 92 by aligning the direction in which the cold air flows. Thus, since the adjustment plate 10 does not attenuate the flow rate of the cold air (it is difficult to attenuate), it is possible to efficiently flow the cold air (blow up).

  And the part which protrudes toward the refrigerator compartment ventilation path 90 (corner part which protrudes toward the ventilation source of cold air) is rounded among the corner parts of the adjustment board 10 so that the flow of cold air can be adjusted efficiently.

  Further, the thickness of the adjustment plate 10 (thickness in the front-rear direction of the refrigerator 100) may be the same as the depth of the grooves of the refrigerator compartment ventilation path 90, the first branch ventilation path 91, and the second branch ventilation path 92. In other words, the adjustment plate 10 may have a thickness that fills the refrigerator compartment ventilation path 90, the first branch ventilation path 91, and the second branch ventilation path 92.

  However, in order to reduce the adjustment level (degree of rectification) of the cool air by the adjustment plate 10, the thickness of the adjustment plate 10 is thinner than the depth of the refrigerator compartment ventilation path 90, the first branch ventilation path 91, and the second branch ventilation path 92. May be. In other words, cold air may flow through a part of the adjustment plate 10 in the front-rear direction of the refrigerator 100.

  Thus, the refrigerator 100 according to the embodiment generates cool air and cools the cool air (the cooler 71, the compressor 72, the first ventilation path 73, the first blower 75, the second blower 77, etc.), The refrigerating room 2 and the refrigerating room ventilation path 90 and the refrigerating room ventilation path that are blown out to the refrigerating room 2 from a plurality of outlets (the refrigerating room outlet 83, the left outlet 83L, and the right outlet 83R) provided in the refrigerator compartment 2. A panel portion that is attached to one surface of the refrigerator compartment 2 including a branch ventilation passage (a first branch ventilation passage 91 and a second branch ventilation passage 92) branched from 90, and is attached to the panel portion 9. The branch portion includes an adjustment plate 10 that adjusts the flow of the cold air in order to adjust the flow rate of the cold air to the branched air passages (the first branch air passage 91 and the second branch air passage 92). .

  Thereby, the flow rate of the cold air to each branch ventilation path can be adjusted efficiently without easing the momentum of the cold air as in the prior art. Since cold air can be sent efficiently in this way, for example, power consumption in a portion (for example, a fan) that sends out the cold air in the cooling unit can be reduced, and power consumption of the refrigerator 100 can be reduced. In addition, by changing the shape of the adjusting plate 10 that is retrofitted to the panel unit 9, the flow rate of cool air to each branch ventilation path can be adjusted afterwards, and the flow rate of cool air to each branch ventilation path can be adjusted flexibly. it can.

  A return port 84 for returning cold air toward the cooling unit (cooler 71, compressor 72, first ventilation path 73, first blower 75, second blower 77, etc.) is provided below the refrigerator compartment 2. 2 is provided on the left side or the right side of the center of 2, the cooling unit sends out cold air from below to above, and the refrigerating room ventilation passage 90 guides the cold air from below to above, and then on the left side of the center of the refrigerating chamber 2. The first branch ventilation path 91 connected to the provided left outlet 83L and the second branch ventilation path 92 connected to the right outlet 83R provided on the right side of the center of the refrigerator compartment 2 are branched and returned. When the opening 84 is provided on the left side of the center of the refrigerator compartment 2, the adjustment plate 10 is formed so as to increase the flow rate of the cold air in the second branch ventilation path 92 rather than the first branch ventilation path 91, and the return port 84 is formed. When provided on the right side of the center of the refrigerator compartment 2, the adjusting plate 10 It is formed so as to increase the flow rate of the cold air in the first branch air passage 91 than the second branch air passage 92

  With this configuration, it is possible to increase the amount of cool air blown from the outlet provided on the opposite side in the left-right direction with respect to the return port 84, compared to the outlet provided on the same side as the return port 84 in the left-right direction. Thereby, the component of the cold air flowing obliquely downward as viewed from the vertical direction from the blower outlet toward the return outlet 84 increases. Therefore, it is possible to intentionally take a cold air path from the blowout port to the return port 84 to cool the refrigerator compartment 2 efficiently. Therefore, the driving of the cooling unit (the cooler 71, the compressor 72, the first ventilation path 73, the first blower 75, the second blower 77, etc.) can be reduced to save power in the refrigerator 100.

  In the refrigerator 100 having the above-described configuration, the cooling unit (the cooler 71, the compressor 72, the first ventilation path 73, the first blower 75, the second blower 77, etc.) sends out cool air from below to above, The air passage 90 guides cold air from below to the upper side, and then is connected to a left outlet 83L provided on the left side of the center of the refrigerator compartment 2 and on the right side of the center of the refrigerator compartment 2. The adjustment plate 10 is branched into a second branch air passage 92 connected to a right outlet 83R provided in the air outlet, and the adjustment plate 10 has an amount of cold air blown from the right outlet 83R and an amount of cold air blown from the left outlet 83L. You may form so that it may become equal.

  With this configuration, it is possible to equalize the cold air blown out from the respective outlets (the right outlet 83R and the left outlet 83L) separated in the left-right direction in the refrigerator compartment 2. Thereby, the inside of the refrigerator compartment 2 can be cooled uniformly.

  Further, the thickness of the adjusting plate 10 may be made thinner than the depth of the refrigerator compartment ventilation path 90. With this configuration, the flow rate of the cold air to each branch ventilation path (first branch ventilation path 91, second branch ventilation path 92) can also be adjusted by adjusting the thinness of the adjusting plate 10. In other words, by adjusting the thinness of the adjustment plate 10, the rectification level of the cold air by the adjustment plate 10 can be adjusted. Therefore, it is possible to flexibly adjust the flow rate of cool air to each branch ventilation path.

  Of the corner portions of the adjusting plate 10, the corner portions protruding toward the cool air sent from the cooling section (cooler 71, compressor 72, first ventilation path 73, first blower 75, second blower 77, etc.) With this rounded configuration, the cold air can be flowed (guided) to each branch ventilation path (first branch ventilation path 91, second branch ventilation path 92) without causing disturbance of the flow of the cold air. ).

  The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.
