The motor 8, the second drive motor 9 composed of a stepping motor that drives the up-and-down wind direction plate 3 and rotates at a predetermined angle, and an electrical component are provided.
[0017]
By the way, the main body D in the prior art described above based on FIG. 3 constitutes the upper part rear surface of the air passage, and includes the casing for accommodating the cross flow fan k and the outlet e. Although it was the structure which consists of the base a and the front panel c provided with the suction grill b attached to the front part, in the present invention, a part of the base a serves as the installation plate A. The purpose of the present invention is to provide a low-priced product without losing quality by reducing the cost of large parts by greatly simplifying the mold for producing the base a. Yes.
[0018]
That is, the main body D includes the cross flow fan 7, the air outlet 2 and the drain pan 5, the casing 11 including the casing cover 10, and the support 12 that supports the heat exchanger 6. Side plates 13 that are joined to the upper portions on both sides of the casing 11 to form both side surfaces of the air passage and that have locking portions C that are detachably locked to the locking claws B of the installation plate A; An electrical component module 14 which is attached to the same side plate 13 and the side portion of the casing 11 and incorporates the first drive motor 8 and the second drive motor 9 to unitize the electrical component, and the front of the casing 11 The front grille 16 is detachably equipped with a suction grille 15 that is attached to the suction port 2 and has an opening communicating with the blower outlet 2. Lock to A's locking claw B It allows to constitute the back of the air passage connected to the casing 11 of the rear portion of the side plate 13 at the upper portion of the contact with the mounting plate A.
[0019]
As a result, the rear surface of the upper portion of the air passage formed in the main body D is located between the base a and the installation space between the wall of the air-conditioned room as in the prior art described above with reference to FIG. It is no longer a double structure with plate A, it is possible to provide low-priced products by reducing waste of components and reducing costs, and at the same time, it can be reduced in weight and easy to handle during transportation and installation. become.
[0020]
In addition, since the electrical component is unitized as an electrical component module 14 incorporating the first drive motor 8 and the second drive motor 9, the assembly workability can be improved and the casing 11 can be improved. The right-and-left width dimension can be reduced, and a significant cost reduction can be realized.
[0021]
In addition, the sealing member 17 is interposed between the installation plate A and the casing 11 and / or the side plate 13 so that the airtightness of the portion is maintained, and the intake air that has not passed through the filter 4 is kept. Part of the suction air is not included in the suction heat. There is no risk of dust adhering to the rear heat exchanger 6b and reducing the heat exchange capability.
[0022]
Further, the heat exchanger 6 is formed in a reverse substantially V shape by a front heat exchanger 6a and a rear heat exchanger 6b in a side view, and the drain pan 5 corresponds to the front heat exchanger 6a. And the rear drain pan 5 corresponding to the rear heat exchanger 6b. The rear drain pan 5 is positioned higher than the front drain pan 5, and the side plate 13 In addition, a water conduit 18 that connects the front and rear drain pans 5 is provided, and the lower end portion of the rear heat exchanger 6b is accommodated lower than the upper rear portion of the casing 11, The drain water dripped from the rear heat exchanger 6b can be smoothly guided from the rear drain pan 5 to the front drain pan 5 without leaking outside through the gap between the casing 11 and the installation plate A. It becomes like this.
[0023]
The side plate 13 is made of synthetic resin, and a joint portion between the side plate 13 and the casing 11 is formed in a housing groove 11a having a substantially concave cross section formed in a side portion of the casing 11 corresponding to a lower portion of the side plate 13. Since the side plate 13 can reduce the manufacturing cost as compared to the case where the side plate 13 is made of sheet metal, the heat insulating performance can be improved and the heat loss can be reduced, and the side portion of the casing 11 can be reduced. Can be joined accurately.
[0024]
A mounting portion for attaching the electrical component module 14 to the side plate 13 and the side portion of the casing 11 includes a lower flange 11c continuously formed with a screw hole 11b on the side portion of the casing 11, and the screw hole 11b is provided with an insertion hole 14a correspondingly formed on the electrical component module 14, and is continuously formed on the electrical component module 14 with an upper flange 14b superposed on the lower flange 11c. And the upper flange 14b is slid onto the lower flange 11c to be superposed, and the auxiliary latch claw 14c is locked to the peripheral edge of the side plate 13 to form the electrical component module. 14 is temporarily fixed, and a screw inserted through the insertion hole 14a is screwed into the screw hole 11b for attachment.
[0025]
In addition, by forming the inclined surface a or the curved surface at the top end portion of the lower flange 11c and / or the bottom end portion of the upper flange 14b, the upper flange 14b is slid from the lateral direction on the lower flange 11c. It can be polymerized smoothly.
[0026]
Further, by superposing the upper flange 14b on the lower flange 11c and temporarily fixing the electrical component module 14, the cross is sandwiched between upper and lower bearing portions provided on both side walls of the casing 11 and the side plate 13. The rotation shaft of the flow fan 7 and the drive shaft of the first drive motor 8 can be positioned concentrically so that the rotation shaft and the drive shaft can be easily and accurately coupled.
[0027]
