Description

[Detailed description of the invention] This invention relates to a separate type air conditioner, in which the space between the box and the casing is made uniform to form an efficient ventilation path for flat indoor units installed near the ceiling. It is intended for this purpose.

This invention will be explained in detail below with reference to the embodiments shown in FIGS. 1 to 3. Reference numeral 1 denotes a box that serves as the outer casing of the air conditioner, and the bottom surface is open.

Reference numeral 2 denotes a lower panel, which is formed into a flat plate shape so as to close the bottom opening of the box 1.

3 is a multi-blade fan, which has a small axial dimension and a large diameter in order to make the box 1 flat.

Reference numeral 4 denotes a motor for driving the fan 3, which is fixed to the inside of the box 1 from below with screws or the like.

5 is a heat exchanger, which is bent into a substantially U-shape.

Reference numeral 6 denotes a drain plate provided below the heat exchanger 5, which is formed from synthetic resin or the like into a substantially U-shape.

Reference numeral 7 denotes an air outlet, which is provided on the front surface of the box 1.

Reference numeral 8 denotes an air suction port, which has openings formed on the left and right side surfaces and the rear surface of the box 1, and is equipped with a filter 9.

Reference numeral 10 denotes a plurality of short bosses protruding from the inside of the box 1, which restrict the blown air passage 11 to a uniform width, and are provided around the motor 4.

Reference numeral 12 denotes long bosses, which are provided at two locations near the air blowing lower area inside the box 1, and at several other locations at the rear.

Reference numeral 13 denotes a fan casing, which has a spiral portion 14 open at the bottom, has an air suction portion 15 at the center of its upper surface, and has fixing fins with the lower edge of the spiral portion 14 directed outward. The part 16 is integrally molded, and this fin part 1
A pair of fitting tubes 17 for the boss 12 are provided at both ends of the air blowing side of the spiral portion 14, and several fitting tubes 17 facing the boss 12 are provided in contact with the rear side surface of the spiral portion 14.

18 is a tapped hole, and the fan casing 13 is made to correspond to the short boss 10 of the box 1, and is secured to the box 1 by screws 19 from below, and the long boss 12 and the fitting cylinder 17 are also screwed together. It is tightened and fixed by 19.

To assemble the air conditioner configured as described above, first, the box 1 is turned upside down, and the motor 4 and the heat exchanger 5 are respectively placed and fixed.

Next, turn over the fan casing 13 and fit the fitting cylinder 17 into the boss 12 integrally molded on the box 1, position it so that the boss 10 corresponds to the threaded hole 18, and tighten it with the screw 19. stick.

Then, after attaching the multi-blade fan 3, the lower panel 2 is fixed to the box 1.

As mentioned above, this idea consists of forming a flat casing with the box and the lower panel, and dividing the inside of the casing into upper and lower sections with the fan casing, which maintains uniform dimensions between the box and the fan casing. Since multiple long and short bosses are integrally molded into the box, it is extremely easy to equalize the space between the box and the fan casing, and it is also possible to efficiently blow air as an air passage, and it is extremely easy to position and fix the casing. , it has great practical effects.
