Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a louver for an outdoor unit of an air conditioner. More specifically, the present invention relates to a louver that is lightweight and easy to carry.

[0002]

2. Description of the Related Art An outdoor unit of an air conditioner blows air with a fan in order to exchange heat with a heat medium. Therefore, hot exhaust air or cold air is sent to the outside. Therefore, when the outdoor unit is installed, for example, with the exhaust port facing the passage, hot air or the like, which is unpleasant for passersby, is sent out. In addition, hot air or cold air from the exhaust port is often installed in a place where it damages plants at home or at Rin's house. Therefore, conventionally, when installing an outdoor unit in such a place, a louver for changing the exhaust flow upward or downward, or left or right is provided at the exhaust port to prevent inconvenience or adverse effects on passersby or plants. I try to reduce it as much as possible. A conventional louver consists of a pair of left and right side plates made of thin steel plates and a plurality of blades fixed between the side plates by spot welding or the like. I try to bring it to the place of installation work of the harmony device.

[0003]

Since the conventional louver is bulky and heavy, it is inconvenient to carry. In particular, if you know in advance that you need a louver, you can bring it in at the same time as the outdoor unit, but usually you will not know whether or not you need a louver after you confirm the installation position of the outdoor unit. They often carry it around in case it happens, or they carry it again when they find it necessary. Therefore, bulky and heavy louvers are extremely inconvenient to handle.

The first aspect of the present invention is to provide a louver for an outdoor unit of an air conditioner which is lightweight and easy to carry.
It is an issue. A second object of the present invention is to provide a louver capable of easily adjusting the angle of the blade on the site of installation work.

[0005]

A louver for an outdoor unit according to the present invention has an upper panel, a lower panel and a pair of side panels each having a rectangular cross section and a hollow panel, and end portions of the four panels. Four corner members each having an insertion portion to be inserted into a hollow end portion of the panel for connecting them to each other at a right angle, and a plurality of blades whose both ends are attached to the inner surface side of the pair of side panels. The structural feature is that it is composed of a plate and a mounting member for mounting on the outdoor unit. The four panels and the vanes may be molded products of synthetic resin or metal having the same cross-sectional shape. When the panel is made of synthetic resin, it can be preferably produced by profile extrusion. Further, it is preferable to form a fitting portion or a mounting hole for fixing each vane plate at a predetermined angle of 1 or 2 or more on the inner surface side of the side panel.

It is further preferable to provide a mechanism for rotatably supporting both ends of each of the vanes with respect to the side panel and adjusting the angles of all the vanes simultaneously. Such an angle adjusting mechanism includes a vertically movable rod passed between upper and lower panels, an engaging portion provided on the rod so as to engage with each vane plate, and a drive for vertically moving the rod. And a locking means for fixing the rod or the driving means at an arbitrary position.

[0007]

Since the louver of the present invention substantially uses a hollow panel made of synthetic resin or metal, it is lightweight and can be manufactured at low cost. Furthermore, since it is composed of four panels, four corner members, and a plurality of blades, it can be compactly packaged and carried, and can be easily assembled at the installation site. If the mounting angle of the blade is selectable, an appropriate angle may be selected during assembly. Further, in the case of having a vane plate angle adjusting mechanism, it is extremely convenient because after the whole is assembled, it can be adjusted to an appropriate angle according to the installation situation.

FIG. 5 is a partial sectional side view showing an embodiment of the angle adjusting mechanism, FIG. 5 is a sectional view taken along the line VV of FIG. 4, FIG. 6 is a perspective view of an essential part showing another embodiment of the louver of the present invention, and FIG. It is a principal part side view which shows other Examples of the angle adjustment mechanism concerning invention.

The louver A shown in FIG. 1 is disposed between an upper panel 1, a lower panel 2, a pair of left and right side panels 3, 4 and a corner member 5 for connecting them in a rectangular frame shape, and the left and right side panels. It is composed of a plurality of blade plates 6 and an angle adjusting mechanism 7 for the blade plates 6. Each of the upper, lower, left and right panels 1, 2, 3, 4 has the same cross-sectional shape,
For example, it can be formed by cutting a long synthetic resin extruded product into a predetermined size. The panel has, for example, as shown in detail in FIG. 3, a hollow form having an outer wall 8 having an elongated rectangular cross section, and two reinforcing ribs 9a and 9b are longitudinally arranged in the outer wall. It is passed. Note that the number of ribs is not particularly limited, and the ribs may not be provided when reinforcement is not required as in the case where the outer wall 8 is thick.

When the two ribs 9a and 9b are provided in this manner, as shown in the panel P of FIG.
Portion 8a between inner (or outer) ribs 9a, 9b
(8b) may be omitted, and so to speak, two rectangular halves may be connected by one connecting portion 10.
Further, as shown by an imaginary line in FIG. 4, one end side P of the panel P is
It may be molded so that a and the other end side Pb form a predetermined angle θ, that is, a cross section having a V shape.
In that case, the molded panel P is unlikely to be warped or twisted in the longitudinal direction, and is straight in the longitudinal direction. This angle θ
Is, for example, preferably about 1 to 10 °, particularly preferably about 3 to 6 °. Further, since the connecting portion 10 is a single thin plate, it is possible to easily bend the halves so that they are flat when assembled. Therefore, the corner member 5 can be easily inserted. Further, even if there are variations in the distortions of the upper panel, the lower panel, and the side panels, they each try to elastically return in the same direction, so the direction to be corrected is always the same. Therefore, the assembly work is easy. In addition, since the force to elastically return is always applied to the engaging portion with the corner member 5, it is firmly coupled during and after the assembly into the rectangular frame shape.

The corner member 5, as shown in FIG.
The corner post 12 has a quadrangular prism shape, and claw members 13a and 13b having a U-shaped cross section and extending from two adjacent surfaces of the corner post 12 so as to open at right angles to each other. Claw member 13
Reference characters a and 13b are insertion portions, and the shape thereof is not particularly limited to a U shape as long as it can be fitted into the hollow portion 14 of the panel.

Further, a tapered or wedge-shaped locking projection 15 is provided at the center of each claw member 13a, 13b, and the locking projection 15 is fitted / engaged with the thin plate on the outer side of each panel. A square locking hole 16 is formed. Further, slits 17 are formed on both sides of the locking projection 15 to facilitate bending. Therefore, the claw members 13a, 1 of the corner member 5
3b can be easily fitted into the hollow portion 14 at the end of the side panel 3, 4, etc., and once fitted, it cannot be easily pulled out by the engagement of the locking projection 15 and the locking hole 16. Be combined. As the corner member 15, a synthetic resin molded product usually molded by injection molding or the like is used.

As shown in FIG. 4, the vane plate 6 has a V-shaped cross section. However, it may be a flat panel. This is hollow except for the central portion 18 in order to reduce the weight while maintaining the rigidity. The vane plate 6 does not necessarily have to be hollow, and may be simply a plate-like member, for example. This product can also be manufactured by cutting a long-shaped synthetic resin extruded product. Each vane plate 6 may be fixed to the side panels 3 and 4 as described later, but in the embodiment shown in FIG. 1, the angle adjusting mechanism 7 can change the direction of the wind coming out of the outdoor unit. Is configured. An example of such an angle adjusting mechanism will be described with reference to FIGS. 4 and 5.

A hole is formed in the central portion 18 of the vane plate 6, and a shaft 20 penetrates through the hole. Both ends of the shaft 20 project from the ends of the blade plate 6, and these projecting portions are rotatably inserted into the holes 21 formed in the side panels 3 and 4. In the embodiment of FIG. 5, the hole 21
Snap-in type grommet 22 made of synthetic resin inside
Is inserted into the hole 21a of the grommet 22 and the shaft 2
The 0 end is inserted. Further, as shown in FIG. 4, a slide bearing 23 is provided on the upper panel 1, and the slide bearing 23 supports a rod 24 extending in the vertical direction so as to be vertically slidable and not to rotate. Further, the lower panel 2 is provided with a slide bearing 25 that supports the rod 24 slidably up and down (see FIG. 1). The lower slide bearing 25 does not have to have a function of restraining rotation so that it does not rotate, but may restrain rotation similarly to the upper slide bearing 25. In this embodiment, as a bearing structure that allows vertical sliding while restraining rotation, a square hole 23a is formed in the slide bearing 23, and a corresponding portion 24a of the rod 24 is formed.
Is formed to have a square cross section, and the two are fitted together.

Further, a portion 24a having a square cross section of the rod 24
The screw parts 24b and 24c are formed on the upper and lower sides of, and the nut 26 is screwed into the screw parts. The nuts 26 are driving means for driving the rod 24 up and down by rotating the nut 26, and are also locking means for tightening both nuts 26 to restrain the vertical movement of the rod at an arbitrary position. Further, instead of the nut 26, a lock means such as a wing nut that does not use a tool is used to drive the rod 2
The upper and lower ends of 4 may be fixed. Also rod 2
An engaging member 27 that engages with the front end portion of the blade 6 is fixed to the blade 4 at a predetermined pitch. The engagement member 27 has a pair of claw portions 27a and 27b that engage with each other to allow the front end portion of the blade plate 6 to move in an arc shape.

In order to assemble the respective parts constructed as described above into the state of the louver A in FIG. 2, first, the lower panel 2 and the left or right side panel 3 (4) are joined by the corner member 5, and then the blades. After inserting one end of each shaft 20 of the plate 6 into the side panel 3 (4), the other side panel 4 (3)
While passing the other end of the shaft 20, the side panel 4 (3) is attached to the lower panel 2 by the corner member 5. Then, the engaging member 27 is passed through the lower panel 2 while engaging the respective vane plates 6, and finally the upper panel 1 is passed through the upper portion of the rod 24, and the upper panel 1 is moved to the left and right sides by the two corner members 5. It may be connected to the panels 3 and 4. Then, after the entire assembly is completed, by operating the two nuts 26 to move the rod 24 up and down, or by previously aligning the rod 24 at an appropriate position and tightening both nuts 26. , Adjust the angle of the vane plate 6 to an appropriate angle. The louver A assembled as described above is attached to the outlet side of the exhaust fan of the outdoor unit by a leg member shown by reference numeral 30 in FIG. The louver A may be mounted upside down or sideways.

When the slide bearing 23 is rotatable with respect to the upper panel 1, the upper panel 1, the one side panel 3 (4) and the lower panel 2 are preliminarily formed into a U shape while incorporating the rod 24. After assembly, the vane plate and the other side panel 4 (3) are assembled, and finally, the rod 24 is rotated together with the slide bearing 23 so that the engaging members 26 and the vane plate 6 are simultaneously engaged. it can.

As described above, the louver A is easy to assemble, and the angle of the blades can be adjusted on the spot. Furthermore, each part is substantially plate-shaped, and if it is put on top of each other, its volume is a fraction of the finished product. Further, in this embodiment, since each panel and the vane are hollow synthetic resin products, they have sufficient rigidity and are lightweight. Even when the panel is a hollow metal molded product, or when the vane plate is a synthetic resin plate member or a metal product, it is lighter and less bulky than conventional ones. As described above, since the louver A is not bulky and lightweight, it is easy to carry it separately from the outdoor unit, and even if it is always carried without checking whether the louver is necessary or not, it is not so convenient. is not.

As the material of the panel and the vane in the present invention, a synthetic resin material having excellent weather resistance and heat resistance, and further a synthetic resin material having excellent cold resistance, are preferable.
For example, polypropylene, polyethylene, polyvinyl chloride, polycarbonate, polyacetal, nylon, A
S resin, ABS resin, etc. are used. Further, those synthetic resin materials containing additives for improving weather resistance are also preferably used. Further, if necessary, a protective coating film may be provided on the resin material. The heat resistance is preferably 70 ° C in consideration of the exhaust temperature of the outdoor unit during the cooling operation, and the cold resistance is preferably -20 ° C in consideration of the exhaust temperature during the heating operation in winter. These synthetic resins are molded into a predetermined shape by a normal profile extrusion molding or the like. Further, a light metal such as an aluminum alloy or a metal such as a galvanized steel sheet can be manufactured from a material having excellent weather resistance, heat resistance, and cold resistance that can be molded (for example, extrusion molding). If desired, a transparent or translucent material may be used. The corner member may be made of the same material as described above, but in the case of a synthetic resin, it is usually manufactured by injection molding or the like, and in the case of a metal, it is molded by cold forging or the like.

In the above-mentioned embodiment, the panel and the vane have a completely closed contour, but a part may be open.
The term "hollow" as used in the claims is a concept including such a part having an open contour. Further, in the embodiment of FIG. 5, the shaft 20 is passed through the center of the blade plate, but as shown in FIG. 6, an end plate 32 having a shaft-shaped protrusion 31 is fitted to the end portion of the blade plate 6. It is possible to adopt various rotatable support structures, such as by allowing them or by inserting and fixing short shafts formed separately at both ends of the blade plate 6.

In the embodiment shown in FIG. 4, the rod 24 slides up and down without rotating, but it may move up and down while rotating. In that case, the engaging member that engages with the blade plate may be configured by, for example, two discs arranged with a space therebetween. Further, by using the inclined cam type engaging member composed of a pair of inclined discs and the like fixed at intervals, it is not necessary to move the rod up and down,
The angle of the blade can be adjusted simply by rotating it.

Further, as shown in FIG. 7, if the blade plate 6 is locked or fixed to the side panel with two shafts 33, 34 or pins, screws, etc., the mounting position of one shaft 34 is changed. Thereby, the angle of the blade can be adjusted stepwise. Further, the louver of the present invention is not limited to the one in which the angle of the vane can be adjusted, and includes one in which the vane is fixed to the side panel so as to be assembled. As such a fixing means, for example, a member having a groove formed on the side panel and fitted to the end portion of the blade plate, or a member fixed to the side panel and having a groove or a protrusion fitted to the end portion of the blade plate is used. can give. Further, the vane plate can be simply fixed by a plurality of screws, but it is preferable to assemble the four panels so that the vane plate is fitted and the angle is restrained because the assembling work is simple. .
