The conventional air conditioner has the following problems.
Since it is configured as described above, there is a problem that if the size differs depending on the capacity of the air conditioner, all casing components cannot be shared. Further, there is a similar problem in the case where the vertical and horizontal dimensions are shared and only the length is changed to form a module. For this reason, the production lot was different for each model, and a small lot was produced, resulting in a high cost.

The present invention was made in order to solve the above problems, and promotes modularization of products,
It is an object of the present invention to obtain an air conditioner in which parts can be shared and assembly can be applied.

A main body casing that is configured by a back plate portion that accommodates the fin-tube heat exchanger and the blower, and an air intake grill disposed in the front portion of the casing,
An air circulation port of the main body casing is provided at the rear end of the side wall portion, and a holding portion having an inverted L-shaped cross-section, and a hooking portion having a U-shaped cross-section and engaged with the holding portion. A rear plate having an air outlet and an air outlet communicating with the air outlet and having a blowout plate formed therein, and the attachment portion provided at the front portion is screwed to the side plate front flange portion to distribute the air flow. And an air blowing box attached so as to cover the side wall of the mouthpiece.

Further, an air circulation port is provided in the side plate having no air circulation port, and the rear end portion of the side wall where the retaining part is not provided is symmetrical so that the screw holes of the retaining part and the side plate flange part are symmetrical in the main body casing. In addition to providing a holding portion having an inverted L-shaped cross-section, a screw hole is provided in the flange portion of the same side plate, and a cross-sectional shape is formed in a U-shape at the rear portion, which has a hooking portion hooked to the holding portion. A cover in which the mounting portion provided on the front portion is screwed to the side plate flange portion is provided.

[0009]

In the present invention, the air blow-out box and the casing body are separated and detachable, so that the air conditioner is modularized, for example, the height and depth dimensions are made common, and the width dimensions are changed. When producing a model with a capacity, the air blow-out box can be shared. Also, for the left,
The blow-out box can be shared by simply changing it to the right main casing, which can be applied to common parts such as modularization, improving productivity.

Further, in the main body casing, since the screw holes of the holding portion and the side plate flange portion are arranged symmetrically, the air blow-out box can be mounted on either the left or right side of the main body casing and the conditioned air can be supplied in a wide range. You can
