[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 Conventional ceiling-mounted air conditioners include, for example,
As shown in the vertical sectional view of FIG. 4, a main body 1 installed in the back of the ceiling has a vertical blower 3 driven by a vertical motor 2.
An indoor heat exchanger 4 and a drain pan 5 for storing drain condensed in the indoor heat exchanger 4 are housed therein.
Is covered with a decorative panel 7 having an air inlet 8 and an air outlet 9 respectively. Thus, the air introduced into the main body 1 from the suction port 8 at the center of the decorative panel 7 passes through the bell mouth 6 and is sucked into the blower 3.
In the process of passing through the indoor heat exchanger 4, the air is cooled or heated to be conditioned air, and is blown into the room from the outlet 9 through the outlet air passage 11.

[0003]

[Problem to be Solved by the Invention] In this type of ceiling-mounted type air conditioner, it is customary to prepare a large number of models according to air conditioning capacity. In this case, a blower 3, an indoor heat exchanger 4, etc. Are selected according to the air-conditioning capacity. However, parts such as the main body 1, drain pan 5, and decorative panel 7 are standardized to the same specification and shared by many models.
However, although the air-conditioning capacity, that is, the blowing capacity, differs for each model, the ventilation area of the outlet air path 11 defined by the main body 1 and the drain pan 5 is constant,
The wind speed in the outlet air passage differs greatly depending on the model.As a result, there are problems such as excessive wind speed causing noise, or excessively low wind speed, conditioned air does not reach the entire room sufficiently and the room temperature is not uniform. Occurs. On the other hand, the ventilation area of the blow-out air passage 11 can be changed by the main body 1 or the drain pan 5, but in such a case, these molding dies must be manufactured for each model, so that the cost is increased.

[0004] The present invention has been proposed in view of such circumstances, and according to the air blowing capacity of each model of the air conditioner, noise can be prevented by a simple attachment member and conditioned air can be transmitted to the room. It is an object of the present invention to provide an embedded ceiling air conditioner.

[0005]

SUMMARY OF THE INVENTION For this purpose, the present invention relates to a ceiling-embedded type in which a lower surface of a main body containing a heat exchanger, a blower and the like is covered with decorative panels each having an air inlet and an air outlet. In the air conditioner, an attachment member having a predetermined size according to a blowing capacity of the air conditioner is attached to the blow air passage in the main body, so that a ventilation area of the blow air passage is adjusted. And

[0006]

According to such a configuration, an attachment member having a predetermined size is attached to the blow-out air passage and the ventilation area thereof is adjusted according to the air-blowing capacity that differs depending on the model of the air conditioner. The discharge conditioned air is blown into the room from the outlet air passage at an appropriate wind speed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partial longitudinal sectional view, FIG. 2 is a horizontal sectional view taken along the line II-II of FIG. 1, and FIG. FIG. In the upper drawing, the same reference numerals as those in FIG. 4 denote the same members as those in the same drawing, and the blow-out air passage 11 defined by the inner wall of the main body 1 and the outer wall of the drain pan 5 is formed by molding the styrene resin shown in FIG. An attachment member 12 made of a product or the like is attached, and is attached to the inner wall surface of the main body 1 in this example. The wind shielding member 12 has a different blowing capacity depending on the type of the air conditioner, that is, a predetermined size corresponding to the air volume of the blower, and adjusts the ventilation area of the blowing air passage 11 to an appropriate size. It has become. In addition,
The blow-out air passage 11 and the outlet 9 of the decorative panel 7 are each formed in a size that can be adapted to a model having the maximum blowing capacity.

The air sent by the blower (not shown) is cooled or heated in the process of passing through the indoor heat exchanger 4 to be conditioned air, and then flows through the blow-out air passage 11 at an appropriate wind speed to form the outlet 9. From the room. Accordingly, by attaching the attachment member 12 having a predetermined size to the blow-out air passage 12 in accordance with the blowing capacity of the air conditioner, the conditioned air flows through the blow-out air passage 11 at an appropriate wind speed for all models. Is suppressed, and the conditioned air is blown into the room evenly, and the room temperature is made uniform. Further, the manufacturing cost of the molding die is reduced as compared with the case where the size of the main body 1 or the drain pan 5 is changed for each model and the ventilation area of the blow-out air passage 11 is adjusted.

[0009]

According to such a structure, the ventilation area can be adjusted by attaching a wind shield member having a predetermined size corresponding to the air blowing capacity of the air conditioner to the blow air path.
For all types of air conditioners, conditioned air is blown into the room from the outlet air path at an appropriate wind speed, so that generation of noise due to excessive wind speed can be prevented, and a uniform room temperature can be obtained. In addition, the production cost of the molding die is inexpensive as compared with the case where the size of the main body or the drain pan is changed for each model of the air conditioner, so that it is economical.

In short, according to the present invention, there is provided a ceiling-embedded air conditioner in which a lower surface of a main body containing a heat exchanger, a blower and the like is covered with decorative panels each having an air inlet and an air outlet. By attaching an attachment member of a predetermined size in accordance with the blowing capacity of the air conditioner to the blowing air passage in the main body, the ventilation area of the blowing air passage is adjusted, so that each of the air conditioners can be adjusted. According to the present invention, the present invention is extremely useful in industry, because it is possible to obtain a ceiling-mounted air conditioner in which noise can be prevented by a simple attachment member according to the air blowing capacity of the model and conditioned air can be transmitted to the room.
