Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fixing structure for a dust collector unit that is fixed to the lower part of the main body of a ceiling-mounted air conditioner with screws.

(Prior Art) Conventionally, an electrostatic precipitator unit has been attached to the lower part of the main body of a ceiling-mounted air conditioner, such as a ceiling-embedded type, with screws, facing the suction port. There are known devices that purify the air being sucked by applying an electric charge to dust in the air and attracting the dust with an electric field of the opposite polarity.

(Problem to be solved by the invention) By the way, when installing such an electrostatic precipitator unit at the bottom of the main body of a ceiling-mounted air conditioner,
Due to its heavy weight, it is necessary to temporarily fasten it in some way before final fastening. For example, as shown in FIG.
A pair of L-shaped cross-sectional fixing plates e provided on opposite sides of the dust collector unit d
, install screw c corresponding to the position of screw c on the above mounting plate.
A fixing hole h is provided, consisting of an insertion hole f through which the dust collector can be inserted, and a long hole g that is continuous with the insertion hole f and whose width is slightly larger than the shaft diameter of the screw, and the dust collector unit d is lifted up and the fixing plate e is opened. After inserting the through holes f into the screws c temporarily fixed to the mounting plate b of the main body a,
It is conceivable to shift the dust collector unit d in the horizontal direction shown by the arrow in the figure so that the screw shaft slides into the elongated hole g, release your hand from the dust collector unit d once at an appropriate position, and fully tighten the screw c.

However, in the above procedure for attaching the dust collector unit d to the main body a, after inserting the screw into the insertion hole f of the fixing plate e, when sliding the screw shaft into the elongated hole, the arrow shown in FIG. As shown in the figure, the dust collector unit d can only be moved in one direction. Therefore, depending on the conditions of the mounting location, such as the position relative to the wall, the condition of piping and wiring, or the relationship with the ceiling hole in the case of an in-ceiling type, it may not be possible to move it in that direction, and the left and right mounting plates may not be able to be moved. There is a problem in that the installation work is difficult, as it requires replacement.

Furthermore, in FIG. 8, due to the asymmetrical shape of the hole in the fixing plate e, the left and right fixing plates e and e do not have the same shape, so two different types of parts are required, which increases the cost. It also has the disadvantage of being expensive.

The present invention was made in view of these points, and its purpose is to make the left and right fixing plates a common part, and to make it easier to install the dust collector unit.
The object is to have a structure with a degree of freedom that allows adjustment from two directions depending on the conditions of the mounting location.

(Means for Solving the Problems) In order to achieve the above object, the solution means of the present invention, as shown in FIG. The object of the present invention is a dust collector unit 3 which is provided with a mounting plate 21 and is mounted to the mounting plate 21 with screws 18. A pair of fixing plates 16 are provided on opposing sides of the upper part of the dust collector unit 3, facing the mounting plate 21, and are temporarily fixed to the mounting plate 16 at corresponding parts of the pair of fixing plates 16. It consists of two circular insertion holes A, A' into which the screw 18 is inserted, and an engagement groove B which communicates both the insertion holes A, A' and into which the screw is slidably but irremovably engaged. Fixing hole 1
7 is formed.

(Function) With the above configuration, in the present invention, the procedure for attaching the dust collector unit 3 to the air conditioner main body 1 is as follows.

That is, when the dust collector unit 3 is lifted and the fixing holes 17 of the fixing plate 16 are inserted into the screws 18 temporarily fixed to the mounting plate 21' of the main body, either of the fixing holes 17 may be inserted depending on the conditions at the installation site. Insertion hole A
Or it is selected whether to insert from A'.
For example, when the screw 18 is inserted through either the insertion hole A or A' without replacing the fixing plate 16 even when the adjustment can only be made from one direction, such as when installing it near a wall, The dust collector unit 3 is moved horizontally in the direction shown by the solid arrow in FIG. The dust collector unit 3 is attached to the main body of the air conditioner by fully tightening the temporary fixing screws 18. As described above, the insertion hole through which the screw 18 is inserted can be selected depending on the conditions at the installation site, thereby facilitating the installation work at the site.

In addition, as shown in Fig. 1, the left and right fixing plates 1
Since the shapes of parts 6 and 16 are the same, they are common parts, reducing the number of parts and reducing overall costs.

(Example) Hereinafter, an example of the present invention will be described based on the drawings from FIG. 2 onwards.

is installed using the following procedure.

As shown in FIG. 7, a pair of mounting plates 21 attached to the main body casing 1 have screws 18 temporarily fixed in advance in screw holes 23 corresponding to the fixing holes 17 of the fixing plate 16. To install the electrostatic precipitator unit 3, first select the appropriate insertion hole A or A' from the fixing holes 17 based on the situation at the installation site, then the electrostatic precipitator unit 3 is lifted and the screw 18 is inserted into the insertion hole A or A'. When A' is inserted and the fixing plate 16 and the mounting plate 21 are brought into close contact, the electrostatic precipitator unit 3 is moved horizontally (in the direction of the solid arrow in FIG. 7), and the shaft of the screw 18 is engaged with the fixing hole 17. It slides through the matching groove 13 and is stopped at a position where the three circular holes 20 of the fixing hole 17 approximately correspond to the screw holes 23 of the mounting plate 21, respectively.

Next, screws 1 are inserted into the screw holes 24 of the mounting plate 21 at the three circular holes 20 on the fixed plate 16.

Two insertion holes A of the fixing hole 17 provided in 6,
It is possible to select which one of A' is inserted through the screw 18 temporarily fixed to the mounting plate 21 in advance. For example, in Fig. 8, when the wall is approaching the front side of the figure, select the insertion hole A or A' as shown in Fig. 8, insert the screw 18, and then insert the electrostatic precipitator unit 3 horizontally as shown by the solid arrow. If the opposite situation occurs, insert the screw 18 through the insertion hole A' or A opposite to that shown in FIG. You can adjust the position by moving horizontally in the direction. In addition, when the position adjustment is completed, the electrostatic precipitator unit 3 is fixed to the engagement groove B of the fixing hole 17 with the two screws 18.
It is in a temporarily fixed state, so it will not fall even if you let go of the hand that was holding it up. Furthermore, since the position of the screw hole 22 of the mounting plate 21 is provided so as to correspond to the vicinity of the center of the engagement groove B of the fixing hole 17 of the fixing plate 16, the screw 18 can reach the insertion hole A on the opposite side. There is no danger of the electrostatic precipitator unit 3 falling. Therefore, in the above embodiment, when installing an air conditioner, it is possible to effectively carry out the procedure from temporary fixing to final fixing according to the conditions of the installation location, so it is possible to save the installation cost of the air conditioner, and also to Since the fixed plates 16, 16 have the same shape, the number of types of parts can be reduced, and overall costs can be reduced.

In the above embodiment, a ceiling-embedded air conditioner has been described, but it goes without saying that the present invention can be similarly applied to a ceiling-suspended air conditioner, and similar effects can be obtained.

(Effects of the invention) As explained above, in the invention, the two insertion holes through which the screws are inserted communicate with the pair of fixing plates that are the connection members for attaching the dust collector unit of the air conditioner. Since we have provided a fixing hole that serves as an engagement groove, even if there are restrictions on the adjustment direction of the screw temporarily fixed to the mounting plate, which is the connecting member on the main casing side, it can be adjusted according to the situation of the mounting location. It is possible to select any one of the insertion holes and perform adjustment and temporary fixing procedures effectively, and since the fixing plates have the same shape, the number of types of parts can be reduced, and overall cost reduction can be achieved.
