DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 denotes a housing of an air conditioner according to the present invention. The housing 1 is formed of a box body including an upper plate 1a, four side plates 1b, and a lower cover plate 1c, and the lower cover plate 1c is freely detachable.

A cylindrical partition 2 is provided in the housing 1, and an air chamber 3 is formed between the partition and an inner surface of the housing 1. The lower cover plate 1c is formed with an air outlet 4 communicating with the lower portion of the air chamber 3 of the housing, and is formed with an air inlet 5 communicating with the inside of the partition body 2.

Further, a filter 6 is provided in the lower part of the partition body 2, a blower 7 is provided above the filter, and a heat exchanger 8 for cooling and heating is provided in the upper part. The air from the blower 7 is cooled or heated by the heat exchanger 8 and sent to the air chamber 3. Therefore, the heat exchanger mounting portion of the partition is open.

Further, in the present invention, an air outlet 9 is provided at an appropriate position of the housing side plate, for example, at each of the left, right, front and rear side plates 1b, and an air inlet 10 formed of a cylindrical body 11 penetrating the housing and the partition body is also provided. These outlets 9 and suction ports 10 are usually closed by blind plates 12, 13 and opening / closing vanes. However, when using a variation described later, the blind plates must be removed or the opening / closing vanes must be opened. Opening.

Further, the air chamber is provided with an opening / closing vane 14 for shutting off the air blow to the outlet of the lower cover plate when the variation is used. In the drawing, reference numeral 15 denotes a drain pan of a heat exchanger, 16 denotes a partition plate for upper and lower chambers which defines a partition inside upper and lower two chambers A and B and to which a blower is attached, and 17 denotes heat from the blower. Duct to send to the exchanger,
M indicates a motor of the blower.

The above-described air conditioner of the present invention is used as a single unit as follows. In this case, the outlet 9 and the inlet 10 of the housing are closed, and the open / close vane 14 in the chamber 3 is opened.

Thus, return air from the room is sucked into the housing from the suction port 5 of the lower cover plate, purified by a filter and sent to the heat exchanger 8 by the blower 7, where it is cooled or heated. The air in the air chamber 3 is sent out to the room from the outlet 4 of the lower cover plate as supply air.

Therefore, in this usage example, the air conditioner of the present invention itself functions to suck indoor return air, exchange heat, and blow out supply air into the room by itself.

In addition to the use examples described above, the air conditioner of the present invention has the following variations.

<Variation 1> An embodiment in which a sub-outlet body 18 is separately used as shown in FIG. In this case, the outlet 9 on the side of the housing is opened, the open / close vane 14 in the air chamber 3 is closed, and the suction port 10 on the side of the housing is kept closed. A sub air outlet body 18 is separately attached to an appropriate position of the ceiling plate 22 in the room, and the sub air outlet body 18 is connected to the outlet 9 on the side of the housing by a duct 19.

Thus, the return room air is sucked into the housing from the suction port 5 of the lower cover plate 1c, and is sent to the air chamber through the air filter, the blower, and the heat exchanger. The air is sent from the air outlet 9 on the side of the housing to the sub-air outlet body 18 by the duct 19, and is sent out from the air outlet body 18 to the room as supply air.

In this case, the air chamber opening / closing vane 1
By opening the 4 properly instead of fully closing it, the temperature-controlled air in the air chamber can also be blown out from the outlet 4 of the lower cover plate as shown by the imaginary line in FIG.

<Variation 2> An embodiment used in combination with the sub-suction port body 20 as shown in FIG. In this case, the outlet 9 of the housing is closed and the outlet 4 of the lower cover plate is closed.
Is open, and the sub air suction port body 20 attached to a required portion of the ceiling plate is
Connect with 1.

In this way, in addition to the indoor air being sucked into the housing from the suction port 5 of the lower cover plate 1c, air is also sucked from the sub-suction port body 20, and the sucked air is blown by the blower 7. The air is sent into the air chamber 3 via the filter 6 and the heat exchanger 8, and the temperature-controlled air in the air chamber is blown into the room from the outlet 4 of the lower cover plate as supply air.

In this mode of use, the air stagnating in the peripheral portion of the room is also sucked into the sub-suction port body 20 as return air, and is blown out from the outlet of the lower cover plate. It is promoted, and the whole room can be air-conditioned to a state with less temperature unevenness.

<Variation 3> An embodiment in which the sub-inlet 20 and the outlet 18 are connected to each other as shown in FIG. In this case, a sub air inlet body 20 and an air outlet body 18 are provided at appropriate places on the ceiling plate of the room, and the inlet body 20 is provided with a duct 21 to the inlet 10 of the housing, and the outlet body 18 is provided with a duct 19. Connected to the outlet 9 of the housing, the lower cover plate is replaced with a blind cover plate 24 having no air outlet and no air inlet.

Thus, the return air from the room sucked from the sub-suction port 20 is sent into the air chamber 3 through the filter 6 and the heat exchanger 8 by the blower into the housing, and the temperature of the air chamber is adjusted. The blown air is blown into the room from the sub outlet body 18 as supply air.

In this embodiment, for example, the air in the other room 25 defined by the partition 23 can be air-conditioned, and it is not necessary to separately provide an air conditioner for the room.

<Variation 4> An embodiment in which the sub-suction port 20 and the outlet port 18 are connected and used as shown in FIG. In this case, a sub air inlet body 20 and an air outlet body 18 are provided at appropriate places on the ceiling plate of the room, and the inlet body 20 is provided with a duct 21 to the inlet 10 of the housing, and the outlet body 18 is provided with a duct 19. It is connected to the outlet 9 of the housing, and the open / close vane 14 is closed.

Thus, the return air from the room sucked from the sub suction port body 20 is sent into the air chamber 3 through the filter 6 and the heat exchanger 8 by the blower into the housing, and the temperature of the air chamber is adjusted. The blown air is blown into the room from the sub outlet body 18 as supply air.

In this embodiment, for example, the partition 23
It is also possible to air-condition the other room 25 defined by the above, and it is not necessary to separately provide an air conditioner for that room.

[0032]

According to the air conditioner of the present invention described above,
In addition to being able to be used by itself, if the location to be air-conditioned is changed,
It is not necessary to move the existing air conditioner, and it is not necessary to provide a separate air conditioner, and it is possible to easily cope with a change in the air-conditioned part.
