BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner embedded in a ceiling.

[0002]

2. Description of the Related Art In recent years, a so-called built-in type, in which a main body of an air conditioner is embedded in a ceiling, has been rapidly progressing in order to effectively use a living room and improve aesthetics. Therefore, it has become necessary to have a configuration of a ceiling-mounted air conditioner that has a part of the same appearance and structure so as to be able to serialize the capacity so as to cope with diversification of the indoor space and required capacity of a house.

Conventionally, this type of ceiling-mounted air conditioner has been
The structure was as shown in FIG. That is, the ceiling-embedded air conditioner 101 has a heat exchanger 103 formed into a circular shape and a drain generated by condensation in the heat exchanger 103 inside a box frame 102 having an opening in the direction of the ceiling. A water receiving tray 104 for receiving water is provided. The water receiving tray 104 has a height up to the upper surface of the underframe 102. By fixing the mounting plate 105 to the underframe 102, the heat exchanger 10
3 can be fixed, and the pipe connection portion of the heat exchanger can be exposed to the outside through the pipe hole of the underframe 102. The heat exchanger 103 further includes an air guider 106 and a makeup grill 107 for guiding the flow of intake air.
Is provided with a motor 108 at the center thereof, and a fan 109 is mounted. By rotating the electric motor 108, the fan can be driven to blow air.

[0004]

[Problems to be Solved by the Invention] However, in such a structure, in order to expand the capacity, the height of the underframe, the water receiving tray, the fan, etc. must be increased with the height of the heat exchanger. Therefore, when trying to make a series of abilities with the same appearance, there are few common parts, many parts will be newly made, and the number of parts in the series will increase and the mold cost will increase. Also, in order to increase the capacity, the number of rotations of the fan is increased to increase the heat exchanger capacity, and thus there is a problem that noise is increased.

In view of the above problems, the present invention divides an underframe, reduces the number of changed parts due to an increase in the height of the heat exchanger, and enables the sharing of parts, reduction of mold cost and reduction of noise. It is intended to be realized.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the underframe of the ceiling-embedded air conditioner of the present invention comprises a substrate having eight rising portions and an outer box side plate having four surfaces. Are configured by combining two of them. By providing a square hole in the rising portion of the substrate and a locking portion on the outer box side plate, the overlap margin can be changed by the locking portion.

[0007]

[Function] With this configuration, when trying to make a series of abilities, the height of the underframe can be changed by changing the overlap between the board and the outer box side plate, so that many parts can be shared, and the series can be developed with a small development cost. It can be expanded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 3, reference numeral 1 denotes a ceiling-mounted air conditioner main body, which is embedded in a ceiling 2, and 3 is fixed below the ceiling-mounted air conditioner main body 1, and It is a makeup grill exposed on the surface of the. Inside the ceiling-mounted air conditioner 1, a heat exchanger 4 and a water receiving tray 5 for receiving drain water generated by condensation in the heat exchanger 4 are provided. 6
Is a substrate having eight rising portions 6a, 7 is a base frame formed by combining two outer box side plates each having a locking portion 7a with two pieces and fixing them with screws 8. I have. Further, the raised portion 6a of the substrate 6 has a square hole 6b for preventing interference with the locking portion 7a. Reference numeral 9 denotes a fan for performing a blowing action, and 10 denotes an electric motor for driving the fan. Reference numeral 11 denotes an air guider which sandwiches the substrate 6 and the water receiving tray 5 and guides suction air. Reference numeral 13 denotes a heat insulating material for preventing the outer box side plate 7 from being cooled and dewed by cold air having passed through the heat exchanger 4. In FIG. 3, the locking portion 7 a of the outer box side plate 7 is locked to the rising portion 6 a of the substrate 6, and the overlapping portion 6 c of the rising portion 6 a of the substrate 6 and the outer box side plate 7 is changed.

A description will be given of a ceiling-mounted air conditioner configured as described above. As described above, as a method for expanding the capacity of the ceiling-mounted air conditioner, the height of the heat exchanger 4 may be increased.
The substrate 6 having the square hole 6b in the a and the two outer box side plates 7 each having four surfaces having the locking portions 7a are combined, and the locking portion 7a of the outer box side plate 7 is mounted on the rising portion 6a of the substrate 6. Lock it,
By changing the overlapping margin 6c, the height of the heat exchanger 4 can be increased, and a series of the same substrate 6 and the same outer box side plate 7 can be used. In order to prevent dew from being attached to the underframe due to the cold wind of the above, the height to the upper surface of the underframe was provided, but this can be insulated by attaching the heat insulating material 13 to the inner surface of the outer box side plate 7, The dew on the outer box side plate 7 is prevented. In order to support the heavy parts such as the heat exchanger 4 and the water receiving tray 5, the support columns 12 are prepared with an object corresponding to the height of the heat exchanger 4. As described above, the height of the heat exchanger 4 can be increased by changing the overlapping margin between the rising portion 6a of the substrate 6 and the outer box side plate 7 and changing the columns.

[0011]

As is apparent from the above embodiment, according to the configuration of the ceiling-embedded air conditioner of the present invention, the substrate having eight rising portions and the outer box side plate 2 having four surfaces are provided. By combining individual parts, all the parts that require a mold can be shared even in a series of abilities, reducing the development cost and development schedule when developing a series of abilities and reducing costs. It has various advantages such as connection.
