EMBODIMENT OF THE INVENTION Below, embodiment of the blower which concerns on this invention is described in detail based on drawing. In addition, this invention is not limited by this embodiment.

Embodiment Mode 1.

1 is a perspective view showing an embodiment of a blower according to the present invention, FIG. 2 is a front view seen from the blower outlet side, and FIG. 3 is a front view seen from the suction inlet side of the blower. The blower 100 has the outer box 1 of the long cube box shape which comprised the outer shell. A blowout port 2 and a suction port 3 are formed on two opposite surfaces of the outer box 1. The blowout port 2 is formed in two stages up and down, and as shown by arrow A in FIG. 1, air is blown out from each of them. The outer box 1 is installed to be suspended from the ceiling, for example, by the attachment plates 7 provided at both ends. In the present embodiment, the pair of mounting plates 7 erected downward on the ceiling surface (not shown) pivots freely on both ends of the outer box 1, whereby it is shown in FIG. As shown by arrow B, the outer box 1 rotates to change the direction of the wind. The attachment plate 7 is covered by the side cover 8. In addition, the blower 100 may be provided not only in the ceiling but also in a vertical wall surface.

4 is an exploded perspective view of the blower. In the outer box 1, the orifice member 36 and the air guide member 37 are housed as the air passage forming member. The orifice member 36 and the air guide member 37 form an air path from the inlet port 3 to the outlet port 2 in the outer box 1. The air guide member 37 divides the air path two times up and down, and eight air paths are arranged in the long side direction of the outer box 1. Corresponding to the individual air paths, a fan 4 for moving air from the inlet port 3 to the outlet port 2 and the electric motor 5 for driving the fan 4 are disposed. The orifice member 36 and the air guide member 37, which are the air passage forming members, are divided in units of two sets of the fan 4 and the electric motor 5. That is, two fan 4 and the electric motor 5, the orifice member 36, and the air guide member 37 corresponding to this comprise one fan unit 40. As shown in FIG. In the outer box 1, four fan units 40 are arranged in the long side direction.

A guard 38 is provided on the suction port side of the four fan units 40 arranged in the long side direction for the purpose of protecting the fan 4, which is a continuous member. Moreover, the support bolt 12 which becomes a center of rotation shaft when it is supported by the mounting plate 7 is erected on the side surface 1a of the outer box 1. At both ends of the long side direction of the outer box 1, the mounting plate 7 of substantially L shape and the side cover 8 which covers this mounting plate 7 are provided. The size of the side cover 8 is 80-150 mm in width and 10-70 mm in thickness.

FIG. 5: is the figure which looked at the blower edge part through the side cover 8, and FIG. 6 is the figure which looked like the part similar to FIG. 5 through the side cover 8, and was seen from the side. FIG. 7 is a perspective view of the blower end portion from which the side cover 8 is removed, and FIG. 8 is a perspective view showing the structure of a power supply line and an aspect of an end divided into three branches. The mounting plate 7 is formed of an approximately L-shaped cross section, and is composed of a fastening portion 7b along the ceiling surface 9 and a main body portion 7a that is bent at a right angle from the fastening portion 7b and extends downward. . The attachment plate 7 of this embodiment is fastened to the ceiling surface 9 by fastening the fastening part 7b with the nut 16 to the hanger bolt 15 extended downward from the ceiling surface 9. It is fixed.

The attachment plate 7 is rotatably holding the outer box 1 through the support bolt 12 in the through hole drilled in the lower end of the main body 7a. In the main body portion 7a, a plurality of angle adjustment holes 7c are perforated in an arc shape with a pitch of 11.25 degrees, and the horizontal state shown in FIG. 5 is selected by fixing any of the angle adjustment bolts 14 by selecting one. It is possible to change the angle between the position where the ejection opening 2 is rotated 90 degrees toward the bottom and the position where the ejection opening 2 is upward by 22.5 degrees.

The power supply line 17 which supplies electric power to the electric motor 5 extends from the ceiling side, pulls in the side cover 8, turns it, and is inserted in the outer box 1. The power supply line 17 is a three-core VVF cable as shown in FIG. 8, and the three electric wires 17a are arranged horizontally to form a cross-sectional flat shape covered with the cover 17b. Even if the rigidity is high and the curve (bending sideways without bending the main surface 17c) in the plane including the main surface 17c is difficult to bend in that direction. Therefore, the power supply line 17 bends in the direction which curves the main surface 17c, or it bends in the direction close to it. In consideration of safety, when the power line of the VVF cable is bent, the technical standard for electrical equipment is specified so that the inner radius of the bent portion is not less than six times the outer diameter of the power line so as not to damage the power line. It is.

As shown in FIG. 7, the power supply line 17 enters into the side cover 8 from the ceiling side, passes through the guide hook 26, and moves downward along the side surface 1a of the outer box 1. The circular arc is bent in a hook-like shape toward the bottom, and is lifted up so as to fall away from the outer box 1, passes through the tension inhibiting part 20, and then reverses. It changes direction while twisting to the outer box 1 side while contacting, and it extends into the outer box 1 through the center hole 18a of the terminal block cover 18 fixed to the side surface 1a. The terminal block (not shown) is accommodated in the space in the outer box 1 in the terminal block cover 18, and the power supply line 17 is electrically connected to the lead wire of the electric motor 5 via this terminal block. In addition, the terminal block cover 18 is fixed to the side surface 1a by the screw 25a, and is removed at the time of the connection operation of the power supply line 17 to the terminal block.

The tension inhibiting portion 20 is for preventing the tension from reaching the connection point between the terminal block or the terminal block and the power supply line 17 when the power supply line 17 is stretched to the ceiling, for example. It is fixed in combination with the attachment plate (7) to the power line (17) is sandwiched and supported by a cord clip (21) provided at the top. The cord clip 21 engages one end with the tension inhibiting unit 20, and the other end is screwed into the tension inhibiting unit 20 with a screw 25b, and between the tension inhibiting unit 20 and the power supply line 17 ), And the power supply line 17 is strongly clamped by fastening with the screw 25b. The tension inhibiting part 20 is provided in the middle of the power line 17 being largely hooked, and the support surface 20a on which the tension inhibiting part 20 supports the power line 17 on the cord clip 21 is provided. And the power supply line 17 having a flat cross section are inclined in a direction in which it is easy to bend. That is, in this embodiment, it inclines 15 degrees with respect to the side surface 1a of the outer box 1 toward the curvature radial direction outer side of the power supply line 17 (FIG. 6).

The induction hook 26 and the induction pole 19 pass through the power supply line 17 so that the power supply line 17 is pulled to the side surface 1a of the outer box 1 without deviating greatly from a predetermined path. Correcting position In other words, the induction hook 26 and the induction pawl 19 are in contact with the power supply line 17 so that the power supply line 17 is pulled by a predetermined path to the side surface 1a of the outer box 1 to correct the position. A positioning member is formed. In particular, both of the induction poles 19 receive a reaction force when the power supply line 17 is bent between the terminal block cover 18 and the tension inhibiting portion 20. If the induction pole 19 is absent, the power supply line ( 17) is a member which does not bend in a predetermined shape and must be present in the structure of the present embodiment.

9 is a front view showing the terminal block cover 18 being peeled off and the terminal block being seen from the entrance opening formed in the side surface 1a of the outer box 1, and FIG. 10 showing the terminal block inside the entrance opening. 11 is a sectional view showing an aspect in which the terminal block is pulled out to the connecting work position, and FIG. 12 is a sectional view showing an aspect in which the terminal block is in the storage position. The terminal block 11 is accommodated in the end space of the outer box 1. The terminal block 11 is comprised including the fastening terminal (connection terminal) 10 mounted in the upper surface.

The fastening terminal 10 has three insertion openings 10a into which the three electric wires 17a of the power supply line 17 are respectively inserted. The three insertion ports 10a open in the surface facing the entrance / exit opening 1b of the fastening terminal 10, and extend in the slide direction mentioned later. If the fastening terminal 10 inserts the electric wire 17a from the insertion hole 10a, the internal immersion structure which is not shown in figure will operate | move, and the electric wire 17a will be pinched | interposed by this, and the electric wire 17a will be after that. It is a structure that cannot be drawn even if a force is applied in the drawing direction.

The slide pedestal 24 is provided in the end space of the outer box 1. The terminal block 11 is mounted on the slide surface 24a formed on the slide pedestal 24 and is slidable. In detail, the terminal block 11 is the connection work position D which makes a part containing the insertion opening 10a of the fastening terminal 10 front side appear from the entrance opening 1b formed in the outer box 1 (FIG. It is possible to slide between 11) and the storage position E (FIG. 12) in which the whole is accommodated in the outer box 1. As shown in FIG. And the slide surface 24a of the slide base 24 inclines with respect to the side wall of the outer box 1 in which the entrance opening 1b was formed (the wall of the outer box 1 which forms the side surface 1a). . The inclination of the slide surface 24a is inclined in the direction of decreasing the angle at which the power line 17 should be bent (the angle at which the power line 17 is bent increases, that is, close to a straight line). The size is an optimal angle considering the structure which accommodates the terminal block 11 in the outer box 1, the operation | movement of the terminal block 11, and the ease of connection work. In the case of this embodiment, the inclination of the slide surface 24a is inclination of about 30 degree so that it may go up inwardly from the entrance opening 1b, for example, when the blower 100 is installed horizontally.

The terminal block 11 is manufactured by bending a flat plate member, for example, and the fastening terminal 10 is mounted on the main part main surface. Then, the slide direction front side of the terminal block 11 is divided into two parts, and the front end portions are bent in a step shape, respectively, to form the handle portions 11a. The rear side of the terminal block 11 is bent to a height exceeding the fastening terminal 10 to form a granular portion 11b. And when the terminal block 11 is in the connection work position D, the edge part which engages with the standing part 11b of the terminal block 11 and hold | maintains the terminal block 11 in the connection work position D is carried out. (Stopper) 24c is provided above the fastening terminal 10.

At the time of power supply connection construction, after removing the terminal block cover 18, the power supply contractor pulls out the terminal block 11 to the connection work position D while holding the handle part 11a. Subsequently, at this position, the terminal block 11 is rotated around the point 24b by holding the handle portion 11a and pulling it downward. And the granular part 11b raises and engages with the edge part (stopper) 24c and is supported. Thereby, when the electric wire 17a is inserted into the fastening terminal 10, the connection operation of the power supply line 17 is satisfactorily performed, without the fastening terminal 10 falling off. When the connection work is completed, the handle 11a is pulled upward to remove the engagement with the end portion 24c in the reverse order, and pushed into the storage position E to cover the terminal block cover 18. In addition, in this embodiment, although the edge part (stopper) 24c is provided above the fastening terminal 10, it is not limited to this, For example, it forms as an end part inside the slide surface 24a, and a handle part The rear end of the terminal block 11 may be engaged by pulling 11a upward. In addition, when the terminal block 11 is pulled out, as a structure for preventing the entire terminal block 11 from being drawn out, the width of the portion behind the terminal block 11 is made larger than the width of the inlet / out opening 1b. Is realized.

As described above, according to the blower 100 of the present embodiment, the terminal block 11 emerges from the entrance opening 1b formed on the side surface 1a of the outer box 1, so that when the power supply line 17 is connected, It is possible to draw out to the connection work position D to improve workability, and to store it in the storage position E after completion of the connection, so that a fire protection safety measure can be made sufficient. Moreover, when the terminal block 11 is in the connection work position D, the edge part (stopper) 24c which engages with the terminal block 11 and prevents the terminal block 11 from falling off to the storage position E side is provided. Therefore, even when the cable having a large rigidity such as a VVF cable is inserted into the fastening terminal 10, the fastening terminal 10 does not drop off and can be connected to the power supply line 17 satisfactorily. Moreover, since the handle part 11a is provided in the slide direction front side of the terminal block 11, it is easy to pull out the terminal block 11. FIG. In addition, since the slide surface 24a of the slide base 24 inclines with respect to the side surface 1a of the outer box 1 in which the entrance opening 1b was formed, it is necessary in the outer box 1 in the long side direction. The space to be reduced can be reduced, and the angle at which the power supply line 17 should be bent is reduced.

The fixing method of the side cover 8 is described. 13 is a perspective view of the side cover 8 viewed from the back side. The side cover 8 is provided in the both ends of the outer box 1 in consideration of designability. The side cover 8 inserts the support bolts 12 (FIGS. 5 and 6) which stand in the outer box 1 into the cylindrical insertion guide 8b which stands in the lower part of a back surface, and uses this as a guide, and the outer box 1 ) And move in parallel to each other, and push the engaging projection 8a having the elasticity set up on the back surface into the engaging hole 7d (FIGS. 5 and 6) formed in the upper portion of the attachment plate 7, The attachment plate 7 is attracted and attached by a pair of magnets 29 provided on both sides of the side direction.

Background Art Conventionally, magnets have also been proposed in the method for preparing a design cover of a general apparatus. Since the cover is fixed by the attraction force of the magnet, screwing or the like is not necessary, and attachment and detachment are easy. However, when the adsorption force of the magnet deteriorates due to aging, there is a fear that the adsorption is peeled off and the cover may fall off.

In this embodiment, by having the structure as described above, the attachment screw is unnecessary, and the workability is improved by making the attachment and detachment process easy. Further, by using the pair of magnets 29 together with the slide indentation structure by the engaging projection 8a and the insertion guide 8b, even if the adsorption of the magnet 29 is peeled off, the side cover is provided by the slide indentation structure. The side cover 8 does not fall by the magnet 29 even if the 8 does not fall and the engagement projection 8a and the insertion guide 8b are peeled off or damaged. In addition, in the side part of the side cover 8, the display (arrow) 31 which shows the direction is engraved so that the peeling direction can be easily understood (FIG. 7).

Next, the fixing method of the fan unit 40 to the outer box 1 is demonstrated. In the fixing method of the present embodiment, the number of screws to be used is greatly reduced. FIG. 14: is a perspective view which shows the aspect in which the fan unit 40 is assembled to the outer box 1, and FIG. 15 is a schematic diagram which shows the screw position in which the quantity of screws was reduced by this embodiment. It is a schematic diagram which shows the screw position of the screw used for the conventional fan unit shown for comparison. FIG. 17 is a schematic diagram showing an aspect in which two neighboring fan units are engaged by one screw in the G position in FIG. 14. 18 is a perspective view of only the first orifice member and the second orifice member in FIG. 17. 19 is an enlarged perspective view of an end portion of the fan unit shown in FIG. 14.

As described above, the fan unit 40 is constituted by two sets of fans 4 and an electric motor 5, an orifice member 36 and an air guide member 37 of a size corresponding thereto. One fan unit 40 is comprised. In the outer box 1, four fan units 40 are housed in the long side direction. The four fan units 40 are fastened to the outer box 1 by the screw 25c and the screw 25d, respectively. The screw 25c fastens the upper edge parts of both ends of each fan unit 40 to the outer box 1. On the other hand, the screw 25d fastens the center lower part of each fan unit 40 to the outer box 1 (FIGS. 14 and 15). In addition, in FIG. 14, only one screw 25c and one screw 25d are described, and the other screw is abbreviate | omitted.

As shown in FIG. 16, one fan unit is comprised by the conventional set of the fan 4 and an electric motor, and the orifice member and the air guide member of the magnitude | size corresponding to this. As for the screw 25 for fastening, four in total is provided in each fan part in one fan unit. Therefore, when the quantity of the fan unit to be equipped increases, the number of the screws 25 for fastening becomes large. As apparent from this, in the fixing method of the fan unit 40 of the present embodiment, the number of screws to be used is greatly reduced. This will be described below.

Here, the two adjacent fan units 40 are demonstrated temporarily as the 1st fan unit 40A and the 2nd fan unit 40B. Upper corner portions (parts of G in FIG. 14) at opposite ends of the first orifice member 36A and the second orifice member 36B, which are orifice members of the first fan unit 40A and the second fan unit 40B. ), Split screw hole pieces 47A and 47B are formed, each of which has a cylindrical screw hole divided into two pieces along an axis. The split screw hole pieces 47A and 47B are abutted with each other to form a cylindrical screw hole. Moreover, the projections 46A and 46B which protrude toward the outer box 1 side are provided in the back surface of this edge part, respectively. On the other hand, in the opening edge part of the outer box 1 corresponding to this, the female screw hole 42 is cut in the position of the screw hole formed by the split screw hole pieces 47A and 47B, and the projection 46A The through hole 33 is opened at the position, and the long hole 34 is opened at the position of the projection 46B.

The through hole 33 and the long hole 34 engage with the projections 46A and 46B, respectively. This restricts the separation between the first orifice member 36A and the second orifice member 36B. In this state, the first orifice member 36A and the second orifice member 36B are joined together by one screw 25c inserted into the screw hole formed by the split screw hole pieces 47A and 47B. The hole corresponding to the projection 46B is a long hole in consideration of the molding accuracy and the assembly error of the orifice member 36. In addition, with regard to the structure of engagement and engagement formed by the through hole 33, the long hole 34, and the projections 46A and 46B, a hole is opened on the side of the orifice members 36A and 36B and the outer box ( A protrusion may be provided on the 1) side.

As for the coupling between the orifice member 36 and the air guide member 37, as shown in FIG. 19, an engagement hole formed at the tip of the extension portion extending from the upper surface of the orifice member 36 in the direction of the air guide member 37. 35 is performed by engaging the engagement convex part 43 formed in the upper surface of the air guide member 37.
