DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling-mounted air conditioner.

[0002]

2. Description of the Related Art A ceiling-mounted air conditioner generally known in the prior art is, for example, shown in FIGS. This conventional ceiling-embedded type air conditioner 1 has an air guider 4, a cross flow fan 5, a heat exchanger 6, and a stabilizer 7 which constitute a blower circuit inside a box frame 3 having an opening in the direction of the ceiling 2. And a water receiving tray 8 that receives drain water discharged from the heat exchanger 6 is provided below the heat exchanger 6. Further, a decorative panel 9 is provided below the air conditioner 1 so as to cover a lower portion of the air conditioner 1 via the ceiling 2. The decorative panel 9 includes a panel main body 10, a suction unit 1,
1, a blow-off unit 12, the suction unit 11 is provided with a suction grill 13 and an air filter 14 inside thereof, and the blow-out unit 12 has a plurality of left and right wind direction changing blades 15 and an outside vertical wind direction changing blade. 16 are provided. A motor 17 for driving the vertical wind direction changing blade 16 is provided at one end of the vertical wind direction changing blade 16, and air is provided inside a panel opening hole 18 formed in the decorative panel 9 at one end side of the blow-out portion 12. A receiving device 19 that receives an operation signal of the harmonic device 1 is provided. Further, a sponge-like sealing material 20 is provided around the opening of the blowing section 12 at the joint of the blowing section 12 and the air conditioner 1.

The air conditioner thus configured receives a driving signal from a wireless remote controller (not shown).
19, the cross flow fan 5 rotates to generate a blowing action, and the indoor air is sucked into the heat exchanger 6 via the suction grill 13 and the air filter 14 to exchange heat, and is further guided to the air guider 4. The blow-out part of the decorative panel 9
The air is released into the room again through 12 and air conditioning in the room is performed.

[0004]

However, in the above-mentioned conventional configuration, the motor 17 and the receiving device 19 are incorporated in the decorative panel 9 which is to be retrofitted at the site.
It is necessary to connect the air conditioner 1 to the motor 17 and the receiving device 19 at the construction site, which requires time and effort for opening the power supply unit of the air conditioner 1 and for connecting the connection wires, as well as incorrect connection. In addition, there is a problem that the decorative panel 9 is always required at the time of the test operation of the air conditioner 1. Further, since the outlet passage is divided into the air conditioner 1 and the decorative panel 9, depending on the height of the installation of the air conditioner 1, it is difficult to secure a seal with the sealing material 20, which is a joining portion thereof, and cold air leaks. There was also a problem that the water was condensed around the space. In addition, there is a disadvantage that the air conditioner 1 is installed above the ceiling 2 and positioning of the main body is difficult. Furthermore, the air conditioner 1
Even if the model name is displayed, it cannot be visually recognized from below because the lower part is covered by the decorative panel 9, and therefore, it is necessary to display the model name of the air conditioner 1 on the decorative panel 9,
The decorative panel 9 lacks commonality.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a ceiling-embedded air conditioner having good workability, high reliability and high commonality.
