  The present invention relates to a duct structure.

  As an air conditioning facility provided in a building such as a house, it is equipped with an air conditioning duct for flowing conditioned air generated by an air conditioner, and a plurality of outlets for blowing the conditioned air flowing through the air conditioning duct toward an indoor space to be air conditioned. (See, for example, Patent Document 1). In such an air conditioning facility, air conditioning (cooling / heating) of an indoor space is performed by conditioned air blown from each outlet.

JP2015-152289A

  Incidentally, some air conditioning ducts have a bent portion in the middle thereof. In this case, the air conditioning duct is formed to include a first duct portion extending in a predetermined direction and a second duct portion extending from the first duct portion in a direction crossing the predetermined direction. In such an air conditioning duct, there may be a case where a plurality of air outlets are provided in the second duct portion. For example, in the 2nd duct part, the case where a blower outlet is each provided in each opposing wall part which opposes a predetermined direction can be considered.

  Here, in such an air-conditioning duct, conditioned air flowing in a predetermined direction in the first duct portion flows into the second duct portion. Therefore, it is conceivable that the conditioned air that has flowed in flows in the second duct portion in a predetermined direction toward the downstream side of the first duct portion (that is, drifts). If it does so, while a lot of conditioned air will blow off from the blower outlet located in the 1st duct part downstream in a predetermined direction among each blower outlet, there will be a little conditioned air from the blower outlet located in the 1st duct part upstream. It is conceivable that non-uniformity occurs in the amount of conditioned air blown out from each outlet, such as being only blown out.

  Moreover, such a problem is not a problem that occurs only in an air conditioning duct having a bent portion, but is a problem that may occur in common in an air conditioning duct in which a drift of conditioned air occurs in the duct.

  Furthermore, such a problem is not limited to the air conditioning duct, but may also occur in a ventilation duct in which air for ventilation flows. The ventilation duct may be provided with a plurality of air outlets for blowing out air for ventilation, and even in this case, it is conceivable that uneven flow occurs in the amount of air blown out from each air outlet.

  This invention is made | formed in view of the said situation, and makes it the main objective to provide the duct structure which can blow off air by desired air volume from each blower outlet in the structure which has several blower outlets. Is.

  In order to solve the above-described problems, a duct structure according to a first aspect of the present invention includes a ventilation duct for flowing air used for air conditioning or ventilation in an indoor space, and an air outlet that is provided in the ventilation duct and blows out the air to the indoor space. The ventilation duct has a predetermined duct portion provided with a first air outlet and a second air outlet as the air outlet, and the first air outlet is located at the predetermined duct portion. It is provided in the surrounding wall part surrounding the space in a duct which is internal space, and the said 1st space part and said 2nd blower outlet of the upstream which leads the said duct space to the said 1st blower outlet in the said duct space A plate-like partition member is provided for partitioning into a downstream second space portion that communicates with the first space portion, and the partition member is provided with a vent hole that communicates the first space portion with the second space portion. It is characterized by being.

  According to the present invention, in the ventilation duct, the first air outlet and the second air outlet are provided in the predetermined duct portion, and the space in the duct of the predetermined duct portion is upstream from the first air outlet by the partition member. The first space portion and the second space portion on the downstream side leading to the second air outlet are partitioned. In this case, the air flowing from the upstream side toward the downstream side in the duct internal space (first space portion) hits the partition member and is guided to the first outlet. For this reason, even when air flows in a space away from the first air outlet in the space inside the duct (that is, when drift occurs), the air is guided to the first air outlet and blown into the indoor space from the air outlet. Can do.

  In addition, since the partition member is provided with a vent hole that allows the first space portion and the second space portion to communicate with each other, a part of the air can be guided to the second space portion through the vent hole. . Therefore, a part of the air can be blown out from the second outlet to the indoor space. Thereby, in a configuration having a plurality of air outlets, air can be blown out from each of the air outlets with a desired air volume.

  The duct structure of the second invention is the duct structure according to the first invention, wherein the predetermined duct portion is a part of the peripheral wall portion and has a pair of opposed wall portions facing each other with the space in the duct interposed therebetween. The first air outlet is provided in one of the opposing wall portions, and the partition member is disposed on the one opposing wall portion from the side of the other opposing wall portion in the space in the duct. As it goes to the side, it is provided so as to be displaced from the upstream side to the downstream side of the space in the duct.

  According to this invention, a partition member is provided with a 1st blower outlet from the other opposing wall part side in which the 1st blower outlet is not provided among each opposing wall part which pinches | interposes the space in a duct. It is provided so as to be displaced from the upstream side to the downstream side as it goes toward the one facing wall portion. In this case, even when air drifts to the side away from the first air outlet (that is, the side of the other facing wall) in the duct internal space, the air flows along the partition member on the side of the first air outlet (that is, It can be smoothly guided to the one opposing wall portion side). Therefore, the fall of the blowing amount (air volume) from a 1st blower outlet can be suppressed suitably.

  The duct structure of a third invention is the duct structure according to the first or second invention, wherein the ventilation duct includes a first duct portion extending in a predetermined direction, and the predetermined duct extending from the first duct portion in a direction intersecting the predetermined direction. A second duct part as a duct part, and the air flows into the second duct part from the first duct part, and the second duct part is formed on the peripheral wall part. It has a pair of opposing wall portions that are a part and oppose each other in the predetermined direction across the space in the duct, and among the opposing wall portions, the upstream side of the first duct portion in the predetermined direction The first blower outlet is provided in the opposing wall portion positioned at a position, and the space in the duct of the second duct portion is located upstream of the internal space of the first duct portion by the partition member. A first space portion and the first duct portion; Characterized in that it partitioned into the second space portion of the downstream non-contiguous with the internal space.

  According to the present invention, the ventilation duct has the first duct portion and the second duct portion extending in the direction intersecting with the first duct portion, and the first duct and the second outlet are formed in the second duct portion. Two air outlets are provided. In this case, air flows from the first duct portion to the second duct portion, and the flowed air is blown out from each outlet of the second duct portion.

  Here, since air flows in a predetermined direction in the first duct portion, when air flows into the second duct portion from the first duct portion, the air is first in the predetermined direction in the second duct portion (space in the duct). It is conceivable that the air flows in the downstream side of the duct part (that is, the air flows in the downstream direction). Therefore, in this case, the air volume from the air outlet (first air outlet) provided in the opposing wall portion on the upstream side in the predetermined direction among the opposing wall portions facing in the predetermined direction in the second duct portion may be reduced. Conceivable.

  Therefore, in the present invention, in such a configuration, a partition member is provided inside the second duct portion (space in the duct), and the air flowing into the second duct portion (first space portion of the space in the duct) is provided by the partition member. It guide | induces to the 1st blower outlet side. Thereby, even if it is the structure which a drift arises in a 2nd duct part, it becomes possible to blow off air with the desired air volume from each blower outlet of a 2nd duct part.

  The duct structure of a fourth invention is the duct structure according to the third invention, wherein the second outlet is provided on an opposing wall portion located on the downstream side of the first duct portion in the predetermined direction among the opposing wall portions. It is characterized by being.

  As described above, in the second duct portion, it is conceivable that air flows in a biased direction toward the downstream side of the first duct portion in the predetermined direction (that is, drifts), and therefore each second facing the predetermined direction in the second duct portion. When the air outlet (second air outlet) is provided in the opposing wall portion located on the downstream side of the first duct portion, the amount of air blown out (air volume) from the second air outlet is large. It is considered to be. In that respect, in the present invention, since the air flowing into the second duct portion is guided to the first air outlet by the partition member, the air volume of the air blown out from the second air outlet can be reduced accordingly. Therefore, even in such a configuration, the air volume of air blown from each outlet can be made comparable.

  The duct structure of the fifth invention is the duct structure according to the third or fourth invention, wherein a separation distance between the first outlet and the first duct part in the intersecting direction is the first duct part in the intersecting direction. It is characterized by being smaller than the length of.

  It is considered that the air flowing into the second duct portion from the first duct portion is likely to cause a drift immediately after flowing into the second duct portion. Therefore, when the 1st blower outlet is provided near the 1st duct part in the 2nd duct part, there exists a possibility that the blowing quantity (air volume) of the air from the 1st blower outlet may become remarkably small. In that respect, in the present invention, since the third invention is applied to such a configuration, even in such a case, air can be blown out from each outlet with a desired air volume.

  A duct structure of a sixth invention is the duct structure according to the fifth invention, wherein the second outlet is provided on an opposing wall portion located on the downstream side of the first duct portion in the predetermined direction among the opposing wall portions. And is opposed to the first air outlet with the space in the duct interposed therebetween, and the partition member is arranged in the space in the duct from the side of the opposing wall where the second air outlet is provided. It is provided obliquely with respect to the opposing wall portion so as to be displaced from the upstream side to the downstream side of the space in the duct as it goes toward the opposing wall portion side provided from the air outlet.

  In this invention, the 2nd blower outlet is opposingly arranged on both sides of the 1st blower outlet, and the space in a duct. In this case, in addition to the first air outlet, the second air outlet is also arranged at a location where drift is likely to occur, and therefore, it is conceivable that the amount of air blown out (air volume) from the second air outlet is significantly increased. In that respect, in the present invention, since the third invention is applied to such a configuration, even in such a case, air can be blown out from each outlet with a desired air volume. Further, since the partition member is provided obliquely with respect to the opposing wall portion, the same effect as that of the second invention can be obtained.

  In a duct structure according to a seventh aspect based on the sixth aspect, the second duct portion has a length in the intersecting direction equal to or smaller than a length in the same direction of the first duct portion. And the second duct portion has an end wall portion that constitutes an end portion on the downstream side of the second duct portion and partitions the duct internal space together with the peripheral wall portion, and the second air outlet is configured to It is provided in the end wall portion in addition to the opposing wall portion, and the second space portion is a space communicating with each of the second air outlets.

  According to the present invention, the second air outlet is provided not only on the opposing wall portion of the second duct portion but also on the end wall portion constituting the downstream end portion of the second duct portion. Yes. In this case, since two second outlets are provided, it is considered that the amount of air blown out from each of these outlets increases and the amount of air blown out from the first outlet decreases accordingly. It is done. In that respect, in the present invention, in such a configuration, the internal space of the second duct portion (the space in the duct) is partitioned by a first space portion that leads to the first outlet and the second outlet that leads to each second outlet. Since it divides into two space parts, it has composition which has three blower outlets, and it becomes possible to blow out air by desired air volume from each blower outlet.

  In the duct structure according to an eighth aspect of the present invention, in any one of the third to seventh aspects, the first duct portion extends further downstream in the predetermined direction than the connecting portion to which the second duct portion is connected. It is characterized by being.

  In this invention, the 1st duct part is extended in the downstream of the predetermined direction rather than the connection part with a 2nd duct part. In other words, the 2nd duct part is branched and provided from the 1st duct part. In such a configuration, since the air flow is generated in the first duct portion toward the downstream side in the predetermined direction with respect to the connecting portion with the second duct portion, there is a drift in the second duct portion toward the downstream side of the first duct portion. It is thought that it becomes easy to occur. In that respect, in the present invention, since the third aspect of the invention is applied to such a configuration, even in such a case, air can be blown out from each outlet with a desired air volume.

  A duct structure according to a ninth invention is the duct structure according to any one of the first to eighth inventions, wherein the ventilation duct has a plurality of divided duct portions divided in an air flow direction in which the air flows, and each of the divided ducts. The parts are connected to each other, and the predetermined duct part is constituted by any one of the divided duct parts.

  According to the present invention, the ventilation duct is divided into a plurality of divided duct portions, and any one of the divided duct portions forms a predetermined duct portion. That is, in this case, each of the divided duct portions is provided with each outlet and the partition member. In this case, when the partition member is disposed in the duct, the partition member may be disposed easily because the partition member is disposed inside the divided duct portion.

These vent holes 55 have a circular shape and are formed in the same size. A plurality of ventilation holes 55 are arranged at predetermined intervals (equal intervals) in the lateral width direction of the partition member 50, and a plurality of ventilation holes 55 are arranged at predetermined intervals (equal intervals) in the vertical direction (height direction) of the partition member 50. Yes. The first space 51 and the second space 52 communicate with each other through these vent holes 55. The vent hole 55 does not necessarily have a circular shape, and may have any shape such as a square shape or a slit shape. Moreover, what is necessary is just to determine suitably the number, arrangement | positioning aspect, etc. of the vent hole 55 according to the air volume of the conditioned air which blows off from each blower outlet 38b-38d.

  Next, the operation of the partition member 50 will be described.

  As shown in FIG. 4, when the conditioned air flows from the first duct portion 35 into the second duct portion 36 (the first space portion 51 of the internal passage 41), the conditioned air blows along the plate surface of the partition member 50. Guided to the outlet 38b side. As a result, even if the conditioned air tends to drift to the side wall portion 42b side (that is, the side away from the air outlet 38b) in the second duct portion 36, the conditioned air is guided to the air outlet 38b side. It becomes possible to blow out into the living room 11 from the exit 38b.

  Further, since the partition member 50 is provided with a plurality of vent holes 55, some of the conditioned air can be guided to the second space 52 through the vent holes 55. Therefore, a part of the conditioned air can be blown out into the living room 11 and the bedroom 13 from the air outlets 38c and 38d continuous with the second space 52. Thereby, in the structure provided with the some blower outlets 38b-38d, it becomes possible to blow off conditioned air by desired air volume from each of these blower outlets 38b-38d. Therefore, for example, the conditioned air can be blown out from the air outlets 38b to 38d with a uniform air volume.

  As mentioned above, according to the structure of this embodiment explained in full detail, the following outstanding effects are acquired.

  In the configuration of the present embodiment in which the conditioned air can be blown out from each of the air outlets 38b to 38d by the partition member 50 and the vent hole 55 provided in the partition member 50, the side wall portions 42a and 42b are provided. By adjusting the inclination (inclination angle) of the partition member 50 with respect to the angle, the number and size (total area) of the vent holes 55, and the like, the air volume of the conditioned air from each of the outlets 38b to 38d can be adjusted relatively easily. It becomes possible. Therefore, in this respect, it can be said that the above configuration is excellent.

  Of the side wall portions 42a and 42b facing in the first direction X, the partition member 50 ends in the second duct portion 36 (internal passage 41) as it goes from the side wall portion 42b side to the side wall portion 42a side. In order to approach the wall part 42e (in other words, to be displaced from the upstream side to the downstream side of the internal passage 41), the side wall parts 42a and 42b are provided obliquely. In this case, even if the conditioned air drifts toward the side wall portion 42 b in the internal passage 41, the conditioned air can be smoothly guided along the partition member 50 to the outlet port 38 b on the side wall portion 42 a side. For this reason, it is possible to suitably suppress a decrease in the amount of air blown from the air outlet 38b (air volume).

  It is considered that the conditioned air flowing into the second duct portion 36 from the first duct portion 35 is likely to generate a drift (a drift toward the side wall portion 42 b) immediately after flowing into the second duct portion 36. Therefore, when the air outlet 38b on the side of the side wall 42a (corresponding to the first air outlet) is provided in the vicinity of the first duct portion 35 in the second duct portion 36, the amount of conditioned air discharged from the air outlet 38b. There is a risk that (air volume) will be significantly reduced. Further, when the air outlet 38d on the side of the side wall 42b (corresponding to the second air outlet) is provided in the vicinity of the first duct portion 35 in the second duct portion 36, the amount of conditioned air discharged from the air outlet 38d. There is a risk that the (air volume) will increase significantly. In that respect, in the above-described embodiment, since the above-described configuration using the partition member 50 is applied to such a configuration, even in such a case, the conditioned air is blown out from each of the air outlets 38b to 38d with a desired air volume. Is possible.

  Further, an air outlet 38e (corresponding to the second air outlet) is further provided in the end wall portion 42e constituting the downstream end portion in the second duct portion 36, and the internal passage of the second duct portion 36 is provided by the partition member 50. 41 is partitioned into a second space 52 that communicates with the air outlet 38e and the air outlet 38d on the side wall portion 42b, and a first space 51 that communicates with the air outlet 38b on the side wall portion 42a. In this case, in the configuration having the three outlets 38b to 38d, the conditioned air can be blown out from each of the outlets 38b to 38d with a desired air volume.

  The air conditioning duct 32 is configured by a plurality of divided duct portions 40, and the partition member 50 is provided in the divided duct portion 40 b among the divided duct portions 40. In this case, when the partition member 50 is disposed in the air-conditioning duct 32, the partition member 50 may be disposed easily because the partition member 50 may be disposed inside the divided duct portion 40b.

  The present invention is not limited to the above embodiment, and may be implemented as follows, for example.

  In the above embodiment, the second duct portion 36 is provided with the two air outlets 38c and 38d as the second air outlet, but only one of the air outlets 38c and 38d is provided. Also good. Also in this case, the conditioned air can be blown out from the one outlet and the outlet 38b (first outlet) with a desired air volume.

  In addition, when only the air outlet 38c (on the end wall portion 42e side) is provided as the second air outlet (that is, when the air outlet 38d is not provided), the inclination of the partition member 50 with respect to the side wall portions 42a and 42b. You may make it change with respect to the case of the said embodiment. For example, it is conceivable to change the inclination of the partition member 50 to the side parallel to the end wall portion 42e. Also in this case, if the partition member 50 divides the internal passage 41 of the second duct portion 36 into a first space 51 that communicates with the air outlet 38b and a second space 52 that communicates with the air outlet 38c. The air volume of the conditioned air from each of the air outlets 38b and 38c can be set to a desired air volume.

  In addition, if the partition member 50 is used to partition the internal passage 41 into a first space portion 51 that communicates with the air outlet 38b and a second space portion 52 that communicates with the air outlet 38c, the partition member 50 is separated from the side wall portion 42a, You may arrange | position so that it may orthogonally cross with respect to 42b. Even in such a case, the conditioned air flowing into the second duct part 36 (the first space part 51 of the internal passage 41) hits the partition member 50 and is guided to the air outlet 38b, so that the air volume from each of the air outlets 38b and 38c is set to a desired level. The air volume can be set.

  -You may comprise the 2nd duct part 36 by the some division | segmentation duct part 40b. In this case, the plurality of divided duct parts 40b are arranged in the second direction Y to constitute the second duct part 36. Moreover, in this structure, you may make it provide the partition member 50 while providing each blower outlet 38b-38d in the division | segmentation duct part 40b on the most downstream side. Even in such a case, the conditioned air can be blown out from each of the air outlets 38b to 38d with a desired air volume in the second duct portion 36 where the drift is generated. In this case, the second duct portion 36 corresponds to a “predetermined duct portion”, and an “induct duct space” is formed by the internal passages 41 of the divided duct portions 40 b constituting the second duct portion 36.

  In the above embodiment, the second duct portion 36 is provided by being branched from the first duct portion 35. For example, the second duct portion 36 is connected to the downstream end of the first duct portion 35, and the first duct is connected. The part 35 and the second duct part 36 may constitute an L-shaped air conditioning duct having one ventilation path. Also in this case, since the conditioned air flowing in the first direction X (corresponding to the predetermined direction) flows into the second duct portion 36, the second duct portion 36 has a drift toward the downstream side in the first direction X. It is thought to occur. Therefore, by providing the partition member 50 in the second duct portion 36, the air volume of the conditioned air from each of the air outlets 38b to 38d can be set to a desired air volume.

  In the above embodiment, the duct structure of the present invention is applied to the air-conditioning duct 32 having the first duct portion 35 and the second duct portion 36 extending in directions intersecting with each other. However, the present invention is applied to an air-conditioning duct having other configurations. You may apply. For example, it is conceivable to apply the present invention to an air-conditioning duct having a bent portion that bends gently so as to form an arc shape. Even in such an air-conditioning duct, it is assumed that drift occurs on the downstream side of the bent portion. Therefore, when a plurality of outlets are provided on the downstream side of the bent portion, each of the outlets (the first outlet and the second outlet) is provided. It is assumed that the amount of air blown from the outlet) is non-uniform. For this reason, in such a configuration, the partition member 50 is provided on the downstream side of the bent portion, and the partition member 50 allows the first space portion to communicate with the first air outlet in the air conditioning duct and the second space to communicate with the second air outlet. In this case, the air volume of the conditioned air from each outlet can be set to a desired air volume. In this case, the air conditioning duct corresponds to the “predetermined duct portion”, and the internal space of the air conditioning duct corresponds to the “duct internal space”.

  Further, even if the air conditioning duct is a straight line portion extending linearly, for example, when the cross-sectional area in the duct has a portion that changes in size on the way, there is a possibility that a drift occurs on the downstream side of the changed portion. In this case, if a plurality of air outlets are provided on the downstream side of the changed portion, the air volume from each air outlet may also be uneven. Therefore, you may make it the air volume from each blower outlet turn into desired air volume by providing a partition member in such a structure.

  In the above embodiment, the air conditioning duct 32 is configured by connecting a plurality of short divided duct portions 40, but the air conditioning duct 32 may be configured to have a long duct (long tube). For example, it is conceivable that the first duct portion 35 of the air conditioning duct 32 is constituted by one long duct.

  In the above embodiment, the partition member 50 is formed in a flat plate shape, but the partition member 50 may be formed in a curved plate shape, for example. In this case, it is conceivable that the partition member 50 is curved so as to be displaced from the upstream side to the downstream side of the internal passage 41 as it goes from the side wall part 42b side to the side wall part 42a side. Specifically, it is conceivable to provide the partition member 50 so as to be convex toward the second space portion 52 side. Also in this case, the conditioned air flowing into the second duct part 36 (the first space part 51) can be smoothly guided along the partition member 50 to the air outlet 38b on the side wall part 42a side.

  In the above embodiment, the partition member 50 is formed of a steel plate (metal plate material), but may be formed of a plate material made of another material such as a resin plate material. Moreover, you may form the partition member 50 with a plate-shaped net-like body (for example, metal net). In this case, the mesh of the net-like body serves as a vent hole that communicates the first space portion and the second space portion.

  In the above embodiment, the duct structure of the present invention is applied to the air-conditioning duct 32 that conveys the conditioned air generated by the air-conditioning device 31. However, for example, the ventilation duct that conveys outside air taken in from the outside to the indoor space as ventilation air The present invention may be applied to. It is assumed that the ventilation duct is also provided with a plurality of air outlets that blow out air for ventilation to the indoor space. In this case, if the present invention is applied, air can be blown out from each of the air outlets at a desired air volume. It becomes.
