BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-directional blow-out type ceiling air conditioner which is installed on a ceiling or the like in a room and is designed to supply cool and warm air in a desired direction in the room.

[0002]

2. Description of the Related Art Conventionally, this type of multi-directional blow-out type ceiling-mounted air conditioner does not have a space for installing a control device such as a valve in the machine because of its structure. Was installed outside the. Therefore, during transportation, there is a great deal of concern that the exposed mechanism portion may be damaged due to contact, and moreover, when it is installed as an exposed type on the ceiling, the exposed portion causes a problem in terms of design. When performing maintenance work such as inspection inside the machine because it is a high place at the time of ceiling installation, an operator enters the ceiling and removes each board of the cabinet to perform internal maintenance or This required extremely difficult work such as lowering the entire machine onto the floor.

[0003]

SUMMARY OF THE INVENTION The present invention has as its main purpose to fundamentally solve the above-mentioned drawbacks, and does not change the overall shape of the valve. It is possible to easily house control equipment such as a machine and to install it in the machine by simply opening the lower panel.Maintenance work such as inspection and cleaning of mechanical parts such as fan, motor, heat exchange coil, drain pan, etc. Can be performed very easily and reliably. Moreover, the present invention intends to provide an economical air-conditioner for multi-directional blow-out type ceiling installation, which has a much better heat exchange efficiency than the conventional air conditioners of the same type and further improves its capacity. .

[0004]

As a means for achieving the above-mentioned object, the present invention, as shown in the drawings, opens a blow-out port 3 and a suction port 5 in four directions of a peripheral portion of a lower panel 2, or in two directions. In the multi-directional blow-out type air conditioner, the blower chamber 12 and the suction chamber 1 which can communicate with the machine room A in the upper part and the lower part in the container 1 and the above-mentioned blow-out port 3 and suction port 5, respectively.
In order to form one branch air-blowing chamber, the above-mentioned L-shaped heat exchange coil 6 is arranged in the machine room A, and the blower port a is opened at the L-shaped diagonal line of the heat exchange coil 6 with respect to the inner surface of the coil. A fan motor support plate 8 having a plurality of fan motors 7 mounted and installed in a substantially V shape is movably supported in the front and rear direction on a mounting plate 9 attached to the inside of the housing 1 through an appropriate fastening adjustment metal fitting 10. It is characterized in that a maintenance hole B having a considerable area is formed between the L-shaped heat exchange coil 6 and the fan motor support plate 8.

[0005]

When the air conditioner having the above-mentioned structure is entirely exposed to the ceiling of the room or is embedded in the ceiling and the fan motor 7 is driven, the air in the room is supplied from the suction port 5 below the machine body. After being sucked into the machine, the air flows into the machine room A above the chamber through the suction chamber 11. Thus, the return air from the inside of the machine or the fresh air taken in from the outside of the machine is heat-exchanged to an appropriate temperature by the L-shaped heat exchange coil 6 by the operation of the fan motor 7, and passes through the blast chamber 12 that branches. Cooling and warming air is fed in a predetermined direction in the room from each of the air outlets 3 opened in the lower panel 2.

Further, by operating the fastening adjustment metal fitting 10 to move the fan motor support plate 8 back and forth,
The airflow of the fan motor 7 and the heat exchange coil 6 are moved in the distance and the airflow of the fan motor 7 is ensured because the airflow opening a is provided obliquely with respect to the heat exchange coil surface. It flows over the entire surface of the exchange coil 6 and has an effect of significantly improving the heat exchange effect. Moreover, since the distance between the blower opening a and the surface of the heat exchange coil 6 can be adjusted to the perspective, it is optional to widen or narrow the airflow, and it is possible to easily obtain the optimum airflow development in the room.

In particular, in the present invention, by moving the fan motor support plate 8 backward in the direction of the arrow, maintenance holes B and C having an arbitrary area are formed in front of and behind the fan motor 7, and thus the center holes are simply formed. The maintenance work inside the machine can be easily and easily performed only by opening the panel 4.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described below. Reference numeral 1 is a rectangular box and four outlets 3 and 5 are provided adjacent to each other at four peripheral portions of a lower panel 2. A central panel 4 is attached to the center of the inside of the panel so as to be openable and closable. Further, although not shown in the drawing, an airflow direction changing blade for adjusting the airflow direction is attached inside the air outlet 3. The blow-out port 3 and the suction port 5 are formed in the machine by a suction chamber 11 and a blow-out chamber 1.
Two branch chambers are connected to each other and connected to the upper machine room A. Inside the machine room A, an L-shaped heat exchange coil 6 is arranged and a coil bending surface is formed at a position corresponding to the L-shaped diagonal line of the coil. A plurality of fan motors 7 for opening the air outlets "a" are attached to the fan motor support plate 8 positioned diagonally to the L-shape in a substantially V-shape, and both side ends of the fan motor support plate 8 are attached. The part is supported by a mounting plate 9 attached to the inner wall portion of the housing 1 so as to be movable back and forth via a fastening metal fitting 10 such as a screw. Further, as an example of the above-mentioned supporting means, if the upper and lower four places of the left and right end portions of the fan motor supporting plate 8 are attached to the attaching plate 9 with the fastening metal fittings 10 such as screws and hinges, it can be installed more stably and movably back and forth. Can be tightened. Furthermore, the forward and backward movements of these fan motor support plates 8 are mechanically and
It goes without saying that it is also possible to automatically move by power, computer operation, or the like. Note that reference numeral 13
Is a cold / hot water pipe, 14 is a valve mechanism, and 15 is a filter.

Further, as described in claim 2, the fan motor support plate 8 is formed in a curved shape with respect to the inner surface direction of the bent side of the L-shaped heat exchange coil 6, so that the air flow from the fan motor 7 is increased. Can be more effectively distributed to the coil surface as compared with a fan motor support plate that is simply located in a slanted shape.

Further, the air outlets 3 are communicated with the lower side of the heat exchange coil 6 without forming the air outlets 3 at the four places on the entire circumference of the lower panel 2 as described above, and the blower chamber 12 is formed in the vertical direction and the lower surface panel 2 is provided with two sides. It can also be used as a two-way outlet type by opening the L-shaped outlet 3.

[0011]

As described above, the present invention is of ordinary straight type,
Alternatively, unlike the ring-shaped heat exchange coil, the entire heat exchange coil is formed into the L-shaped heat exchange coil 6, so that it can be easily accommodated in the machine without installing a control device such as a valve outside the machine. It is possible to solve all of the drawbacks exposed to the outside, which is extremely good in terms of design. In addition, a plurality of fan motors 7 each having a blower port a opened at a position corresponding to a diagonal line of the L-shaped heat exchange coil 6 are provided. Since the fan motor supporting plate 8 is attached to the fan motor supporting plate 8 in a substantially V shape and the fan motor supporting plate 8 is movably installed in the front and rear direction via the fastening member 10, the supporting plate 8 is moved backward. A maintenance hole B is provided inside the heat exchange coil 6.
However, in the rear portion of the fan motor 7 as well, an inspection hole having an area of an arbitrary size can be freely formed at the front and rear of the fan motor 7 such as the maintenance hole C, and can be formed at the front and rear of the fan motor 7. Inside the machine room A, which has been said to be very difficult by simply opening the central panel 4 at the time of maintenance work through the holes, particularly in the deep part, various heat exchange coils, fan parts, motors, drain pans, and other various mechanical parts. There is no need to take any maintenance work such as cleaning, inspection, replacement, etc. of the entire machine, and it is extremely easy and reliable to perform it from below the machine with the air conditioner installed state.
In addition, the maintenance holes B and C described above naturally provide a sound-deadening function during ventilation and ventilation, which is a very quiet air conditioner for a multi-directional blow-out type ceiling installation. Have

Further, according to the present invention, since the air outlet a of the fan motor 7 is obliquely attached to the bent inner surface of the L-shaped heat exchange coil 6, the air flow from the fan motor 7 is the above L-shaped. Directly to the inner surface of the recess of the heat exchange coil 6,
Besides, the air is smoothly sent, and thus more reliable heat exchange can be obtained, and further, the air flow is further expanded by the action of the backward movement of the fan motor support plate 8, and the air is sent over the entire surface of the L-shaped heat exchange coil 6. It also has an economic effect such that a very effective heat exchange efficiency such as application can be easily obtained.

Further, as described in claim 2, by forming the fan motor support plate 8 in a curved shape with respect to the direction of the inner surface of the L-shaped heat exchange coil 6 on the bending side, the air flow from the fan motor 7 is generated. The coil surface can be naturally and efficiently distributed, and at the same time, the curved shape of the support plate 8 has the effect of significantly increasing the strength of the entire support plate.

Further, the present invention is not limited to the four-way outlet type as described above, but as described in claim 3, the blower chamber 1 in the vertical direction is provided below the blower passage of the L-shaped heat exchange coil 6.
It is also possible to directly pass the cold and warm air to the L-shaped two-way air outlet 3 by forming the air outlet 2 in the shape of 2 and forming the air outlet 3 in the L shape below the blower chamber 12. It is the most suitable air conditioner for two-way blow-out type air conditioners installed in a room, etc. In addition, it is an optimum air conditioner as an energy-saving device because it can be easily requested to develop air conditioning according to the indoor environment.
