Description

The present invention relates to an air-conditioning blowout device generally referred to as a line type, and a discharge portion forming cylinder used therein,
Specifically, in a long blowing box, one of the two face parts adjacent to each other in the longitudinal direction of the box (in other words, a cross-sectional view of the box) is used as the blowing face part, and the other face part is connected. A blower for air conditioning in which a slit-like air outlet extending in the longitudinal direction of the box is formed in the air outlet surface as the surface portion, and a connection port of the air supply duct is formed in the connecting surface portion, and a discharge portion forming cylinder used therefor About the body.

  Conventionally, in the air-conditioning blowout device as described above (see FIGS. 7 and 8), the slit-like blowout port 2 in the blowout surface portion 1 a of the blowout box 1 is a long one extending in the longitudinal direction of the blowout box 1. On the other hand, in order to improve the air conditioning performance, in order to make the blowing state of the air A (particularly the blowing wind speed and blowing direction) from the long blower outlet 2 uniform in the blower outlet longitudinal direction, a plurality of connection ports 4 are used. Are formed on the connection surface portion 1b of the blowing box 1 in a state of being dispersed in the longitudinal direction of the box, and a plurality of air supply ducts 3 are connected in parallel to the blowing box 1, whereby the blowing box 1 The air supply state to the box is dispersed in the longitudinal direction of the box, so that the air blowing state from the long outlet 2 is made uniform.

  Further, in the case where only one connection port 4 for the air supply duct 3 is formed at the central portion in the box longitudinal direction of the connection surface portion 1b of the blowing box 1, the porous plate-like body is extended over the entire length in the box longitudinal direction. There is also an instrument that is installed inside the blowing box 1 and uniformizes the blowing state of the air A from the long air outlet 2 by guidance and wind regulation by the long porous plate-like body.

  However, in the former prior art in which a plurality of air supply ducts 3 are connected to one blowing box 1, there are a large number of facilities of the air supply ducts 3, which increases the equipment cost and lowers the installation efficiency of the equipment. On the other hand, in the latter conventional technique in which a long porous plate-like body is installed inside the blowout box 1, the blowout box 1 is expensive, which increases the equipment cost. However, there is a problem that the construction efficiency of the equipment is lowered due to the increase in weight, and in the case of air-conditioning equipment such as buildings, there are many cases of this type of blowing equipment, so the above problem becomes remarkable.

  That is, when only one connection port 4 is provided in the connection surface portion 1b of the blowing box 1 (see FIGS. 9 and 8), the air supplied from the air supply duct 3 to the inside of the blowing box 1 through the connection port 4 A is the inside of the blowing box 1 in a radial direction when viewed from the center axis direction of the connection port 4 after colliding with the surface portion 1d facing the connection port 4 in the blowing box 1 (that is, the facing surface portion of the connection surface portion 1b). Of the radial diffused air A, which is indicated by a thin broken arrow pointing toward the blowout surface portion 1a on which the blowout port 2 is formed (strictly speaking, it flows toward the slit-like blowout port 2 and blows out the blowout port. 2), when viewed alone, it proceeds in a concentric state in which the radial airflow direction and the airflow velocity are kept uniform.

  Therefore, in the radial diffused air A after the collision, the air flow toward the blowout surface portion 1a (arrow with a thin broken line), when viewed alone, at the central portion in the longitudinal direction of the blowout port 2, It is blown out from the blower outlet 2 at a large blown wind speed that is good in air conditioning perpendicular to the opening surface and still does not progress so much in the radial direction. The air blows out from the air outlet 2 in a slanting air direction that is inclined outward in the longitudinal direction of the air outlet 2 and at a small air velocity at which radial diffusion has progressed.

  On the other hand, in the radial diffused air A after the collision, in the longitudinal direction of the outlet box 1 when viewed from the center axis direction of the connection port 4, the both end face parts 1 e and 1 f (left and right side parts in FIG. 9) and the outlet box 1 With respect to what is indicated by the one-dot chain line arrow in the figure that faces the opposing surface portion 1c (upper surface portion in FIG. 9) of the blowout surface portion 1a, the progress is blocked by the respective surface portions 1e, 1f, and 1c facing each other. In the blowout box 1, both ends in the longitudinal direction are turned toward the blowout surface portion 1a, and when only it is viewed alone, the blowout port 2 is mainly formed from the portion near the both longitudinal ends of the blowout port 2. It will be in the state which blows off in the direction substantially orthogonal to an opening surface.

  From the above, when only one connection port 4 is provided in the connection surface portion 1a of the blowing box 1, the air outlet 2 can be seen from the whole of the air A supplied from the connection port 4 to the inside of the blowing box 1. From the central portion in the longitudinal direction, air A (thin broken arrow) directed toward the blowing surface portion 1a due to the radial diffusion mainly due to the collision is blown out in a blowing direction orthogonal to the opening surface of the blowout port 2. From the part near the longitudinal direction both ends of the air outlet 2, air A (arrows with thin broken lines) directed toward the air outlet surface portion 1 a due to radial diffusion due to collision, and surface portions 1 e other than the air outlet surface portion due to radial diffusion due to collision. A state in which detoured air A (arrows indicated by alternate long and short dash lines) that has finally turned toward the blowing surface 1a toward 1f and 1c is in a merged state and is blown out in a blowing direction determined by the merging ratio of the air become.

  However, in the blowout device that only provides one connection port 4 in the connection surface portion 1b of the blowout box 1 (that is, a conventional general device that does not take any measures to make the blowout state uniform), the longitudinal direction of the blowout port 2 The merging ratio of the air A in the air blowing due to the merging as described above occurring in the portions near both ends is fixed such as the shape of the blowing box 1 and the dimensions of each part, the diameter of the connection port 4, the amount of air supplied from the connection port 4, and the like. Depending on various conditions, it is determined in an uncertain state, and this is one of the causes, and the air A blowout state from the slit-like air outlet 2 becomes uneven in the longitudinal direction of the air outlet. There was found.

In contrast, in the first or fourth characteristic configuration of the present invention (see FIGS. 2 to 4), the supply air A from the air supply duct 3 guided by the discharge cylinder 5 collides with the collision surface 6 for diffusion. As a result, the supply air A is diffused radially in the direction of the center axis of the connection port 4 (that is, the direction of the cylinder axis of the discharge cylinder 5), and the diffusion air A of the discharge cylinder 5 is diffused. Although it is made to discharge into the inside of the blowing box 1 from each opening part 8, 9A, 9B formed in a surrounding surface part, it is on the opposing surface part 1c (upper surface part in a figure) of the blowing surface part 1a in the blowing box 1 among this diffused air A. For the heading, discharge into the blowing box is prevented or restricted by the wind shield 7 provided in the discharge cylinder 5.

  In other words, due to the discharge prevention or discharge restriction by the wind-shielding portion 7, the blow-off surface portions are finally formed at both ends in the longitudinal direction inside the blow-out box 1 toward the surface portions other than the blow-out surface portion 1 a of the diffused air A after the collision. In the detoured air changing to the direction 1a (indicated by the one-dot chain line arrow in FIG. 4), the one changing in the direction of the blowing surface 1a at one end in the longitudinal direction inside the blowing box 1, and for blowing The indirect blowing opening 9A facing the one end surface 1e in the longitudinal direction of the blowing box 1 and the blowing ratio of the air volume ratio of the other end in the longitudinal direction inside the box 1 to the direction of the blowing surface 1a. It becomes possible to define clearly by setting the relative opening width d2 with respect to the other indirect blowing opening 9B facing the other end face 1f in the longitudinal direction of the box 1 (note that Unless otherwise stated, it refers to an opening width in the cylinder axis direction of the ejection cylinder portion 5 and the opening width).

  In addition, the indirect blowing openings 9A and 9B are finally opened with a larger opening width than the direct blowing opening 8 having a constant opening width. The air volume of the detoured air A indicated by the one-dot chain line arrow in the figure which changes in the longitudinal direction at both ends in the blowing box 1 toward the blowing surface 1a (that is, the direct blowing opening of the discharge cylinder 5) Among the air A shown by the thin dashed arrows in the figure discharged from the blower box 1 toward the blowout surface portion 1a of the blowout box 1, those blown obliquely from the portions near the longitudinal ends of the blowout port 2 are described above. The amount of air that is pushed and changed in the direction orthogonal to the opening surface of the outlet 2 by merging is sufficient for the amount of air discharged from the opening 8 for direct blowing on the appearance of the change in direction) Can be secured.

  Further, by setting the relative opening widths d2 and d1 for the indirect blowing openings 9A and 9B and the direct blowing opening 8, one of the indirect blowing openings 9A and the other indirect blowing opening described above. Combined with the relative opening width setting for the portion 9B, it becomes possible to clearly define the merging ratio of the air A of the air blowing by the merging as described above at each of the portions near the both ends in the longitudinal direction of the outlet 2. .

That is, according to the first or fourth characteristic configuration of the present invention, regardless of fixed conditions such as the shape and each part size of the blowing box 1, the diameter of the connection port 4, and the amount of air supplied from the connection port 4. By appropriately setting the opening widths d1 and d2 of the respective openings 8, 9A and 9B provided in the discharge cylinder 5, the air blown out by the merging as described above at the portions close to both ends in the longitudinal direction of the outlet 2 The merging ratio of the air A is defined as a suitable merging ratio as much as possible (that is, a suitable merging ratio that can make the blowing state of the air A from the outlet 2 as uniform as possible in the longitudinal direction of the outlet as shown in FIG. 5). Thereby, the blowing state of the air A from the long slit-shaped air outlet 2 can be effectively uniformed in the longitudinal direction of the air outlet.

And the blowing state of the air A from the long blower outlet 2 is effectively equalized only by setting the opening widths d1 and d2 of the openings 8, 9A and 9B in the discharge cylinder 5 as described above. As a result, the air supply duct for one blowing box 1 can be compared with the above-described conventional technique in which the blowing state is made uniform only by connecting a plurality of air supply ducts 3 in parallel to the blowing box 1. The number of connections of 3 can be reduced to one (or reduced), and the equipment cost can be reduced and the construction efficiency of the equipment can be increased.

  Compared to the above-mentioned latter prior art, in which the blowing state is made uniform only by installing a long perforated plate-like body inside the blowing box 1, the perforated plate-like body is equipped in the box. It can be made unnecessary (or lightened), and the blowing box 1 can be made inexpensive and lightweight, thereby reducing the equipment cost and increasing the construction efficiency of the equipment.

In the implementation of the first or fourth characteristic configuration , the collision surface portion for diffusion is formed by a dedicated surface portion 6 provided at the distal end portion of the discharge cylinder portion 5, or the connection surface portion 1 b in the blowing box 1. Any part of the facing surface portion 1d facing the tip of the discharge cylinder portion 5 may also be used as the collision surface portion for diffusion.

In addition, a configuration in which the opening width d1 of the direct blowing opening 8 is changed in the circumferential direction of the discharge cylinder portion 5 is also conceivable. However, in the first or fourth characteristic configuration , as a more desirable configuration, direct blowing The opening 8 has an opening width d 1 that is constant in the circumferential direction of the discharge cylinder 5.

In the fifth characteristic configuration of the present invention, since the direct blowing opening and the indirect blowing opening are continuous in the circumferential direction of the discharge cylinder , the following functions can be obtained.

That is, according to the fifth characteristic configuration , the discharge cylinder in the discontinuous portion is formed in the discontinuous portion in the circumferential direction of the discharge tube portion as compared with the direct discharge opening portion and the indirect discharge opening portion. Non-uniformity in the air blowing state at the air outlet caused by the influence of the peripheral surface portion of the part blocking the air discharge from the discharge cylinder, and in this respect, the air from the slit air outlet Can be made more effective in the longitudinal direction of the outlet.

  Further, by making the direct blow opening and the indirect blow opening continuous in the circumferential direction of the discharge cylinder, in the manufacture of the discharge cylinder, the direct blow opening and the indirect blow opening are Substantially one opening can be formed in the discharge cylinder, thereby facilitating manufacture.

In the 3rd or 4th characteristic structure of this invention, since the said opening part for direct blowing is arrange | positioned in the state which faces the said blower outlet in the longitudinal direction view of the said blowing box , the following function can be obtained.

That is, according to the third or fourth characteristic configuration , the direct blowout opening is formed by facing the direct blowout opening and the blowout outlet in the longitudinal direction of the blowout box (in other words, in cross-sectional view). The air discharged from the air can be passed smoothly and stably to the air outlet, and the non-uniformity of the air blowing state due to the turbulence of the airflow can be effectively suppressed. The air blowing state can be made more effective in the longitudinal direction of the air outlet.

  In addition, since the discharge air from the direct outlet can be passed smoothly and stably to the outlet, the pressure loss of the air in the outlet box can be effectively reduced, and the blowing power is reduced. It may be advantageous in terms of the aspect.

In the sixth characteristic configuration of the present invention, the opening width in the cylinder axis direction of the discharge cylinder portion increases as the indirect blowing opening portion moves away from the direct blowing opening portion in the circumferential direction of the discharge cylinder portion. The following function can be obtained because of the structure .

That is, according to the sixth feature configuration , the opening width of the portion near the direct blowing opening in the circumferential direction of the discharge cylinder portion in the indirect blowing opening is made small close to the opening width of the direct blowing opening. In addition, while suppressing the sudden change in the circumferential direction of the discharge cylinder portion of the air discharge amount in the portion from the direct blowout opening portion to the indirect blowout opening portion, it faces the blowout surface portion at both ends in the longitudinal direction inside the blowout box. The amount of air that changes direction (i.e., the air discharged from the direct blowout opening that is blown obliquely from the portion near the both ends in the longitudinal direction of the blowout outlet becomes the opening surface of the blowout outlet by the above-mentioned merging. On the other hand, it is possible to sufficiently ensure the air volume of the air that is pressed and changed in the direction orthogonal to the side.

  Then, the sudden change in the circumferential direction of the discharge cylinder portion of the air discharge amount in the portion from the direct blow opening to the indirect blow opening can be suppressed, so that the direct blow opening and the indirect blow opening can be suppressed. The flow of air discharged from each of the sections toward the ends in the longitudinal direction of the outlet can be made smooth and stable, so that the portions closer to the ends in the longitudinal direction of the outlet As described above, the change in the blowing direction due to the merging can be made smooth and stable, and the air blowing state from the slit-like outlet can be made more effective in the longitudinal direction of the outlet. can do.

In the implementation of the sixth characteristic configuration , it is desirable that the opening width of the indirect blowing opening is gradually increased as the distance from the direct blowing opening in the circumferential direction of the discharge cylinder is increased. It is desirable that the opening width of the end portion of the opening portion for indirect blowing on the side of the opening portion is an opening width substantially equal to the opening width of the opening portion for direct blowing.

In the first characteristic configuration of the present invention , an adjustment opening is formed in the indirect blowing opening at a portion of the peripheral surface portion of the discharge cylinder portion facing the opposed surface portion of the blowing surface portion in the blowing box. The following functions can be obtained because they are formed in a continuous or close arrangement .

That is, depending on various conditions, even if the opening area of the opening for indirect blowing is ensured as large as possible, the air volume of detoured air that changes in the direction of the blowing surface at both longitudinal ends inside the blowing box (i.e., In some cases, it is difficult to ensure a sufficient air flow rate for the change in the blowing direction due to the above-mentioned merging. However, even in such a case, according to the first feature configuration , both longitudinal ends in the blowing box Thus, it is possible to sufficiently secure the air volume of the air that is changed in the direction of the blowout surface portion by the sum of the air discharge amount from the indirect blowout opening and the air discharge amount from the adjustment opening.

In the second or fourth characteristic configuration of the present invention, there is provided a discharge portion forming cylinder that is inserted into the connection port from the outside of the blowout box and attached to the blowout box. Since the insertion start end portion is the discharge cylinder , the following functions can be obtained.

In other words, according to the second or fourth feature configuration , the discharge portion forming cylinder in which each of the openings is formed in the peripheral surface portion of the insertion start end side portion, the insertion start end portion of the outlet box from the connection port. By inserting it into the connection port from the outside of the blowing box so as to protrude into the inside and attaching it to the blowing box, it is possible to equip the blowing box with the discharge cylinder part.

  That is, the blowout device of the present invention can be obtained simply by attaching the discharge portion forming cylinder to the blowout box using a conventional blowout box that is not equipped with the discharge tube portion in the blowout box. .

  In addition, it is possible to further facilitate the manufacture of the instrument by forming each opening portion of the required opening width in the discharge portion forming cylinder before being attached to the blowout box. Since it is inserted into the connection port from the outside of the blowout box and attached to the blowout box, the discharge part forming cylinder can be easily attached to the blowout box even at the facility site of the blowout box. It can be made more advantageous in terms of production, cost and construction.

In the third or fourth feature configuration of the present invention, when the discharge portion forming cylinder is inserted into the connection port, the discharge portion forming portion is brought into contact with an opposing surface portion of the connection surface portion in the blowing box. A stopper for positioning the cylinder at a position where the opening for direct blowing faces the outlet as viewed in the longitudinal direction of the blowing box is provided at the distal end of the insertion start side portion of the discharging part forming cylinder. Therefore, the following functions can be obtained.

In other words, according to the third or fourth feature configuration , the discharge portion forming cylinder is inserted into the connection port until the stopper portion abuts against the opposing surface portion of the connection surface portion in the blowing box and further insertion is impossible. simply, the air outlet of the discharge part forming the cylindrical body directly outlet opening is in the longitudinal direction as viewed in outlet boxes directly face can be reliably positioned in position, This ensures that the fabrication of the vessel member It can be made easier.

The opening for direct blowing is an opening having a constant opening width in the cylinder axis direction of the discharge cylinder part in the circumferential direction of the discharge cylinder part,
Since the opening for indirect blowing is an opening having a larger opening width in the cylinder axis direction of the discharge cylinder than the opening for direct blowing , the following function can be obtained.

That is, in the seventh or eighth characteristic configuration, the cylindrical body is inserted into the connection port from the outside of the blowing box in a state where the insertion start end portion projects from the connection port to the inside of the blowing box. By attaching to the box, it is possible to equip the discharge box with the discharge cylinder part with the insertion start end portion of the cylinder as the discharge cylinder part.
