Abstract

<P>PROBLEM TO BE SOLVED: To solve problems in a conventional air conditioner wherein, since an air discharged from an upper part blowout port side is not allowed to pass the entire part of a heat exchanger and an air discharged from a lower part blowout port side is not allowed to pass the entire part of the heat exchanger, a temperature distribution in a room is increased depending on the operating state of an air conditioner. <P>SOLUTION: In this air conditioner, a movable partition plate arbitrarily movable in the vertical direction and partitioning the air passages of cross-flow fans installed on upper and lower sides between the heat exchanger and the rear face of a chassis is installed inside a casing. The areas allowing the air discharged from the upper blowout port and the air discharged from the lower blowout port to be passed therethrough can be freely changed. Accordingly, the air conditioner can be operated so that the temperature distribution in the room can be remarkably improved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an indoor unit of an air conditioner that performs indoor cooling or heating.

  Conventionally, this type of air conditioner has a plurality of air outlets, and each air outlet has a function of changing the area through which the sucked air passes through the heat exchanger with a damper (for example, a patent) Reference 1).

FIG. 2 is a schematic cross-sectional view of a conventional air conditioner described in the patent literature. As shown in FIG. 2, a suction port 11 is formed in the front surface of the chassis 10 and a blowout port 15 is formed in the vertical direction of the suction port 11. A heat exchanger 12 and condensation condensed in the heat exchanger 12 are formed inside the chassis 10. A drain pan 13 for storing water and a cross-flow fan 14 connected to a motor are arranged in the vertical direction of the suction port 11, and the air discharged to each blow-out port 14 is heat exchanged inside the chassis 10. It comprises a damper 16 that changes the area for heat exchange with the vessel 12 and a stopper 17 that contacts the damper 16.

  However, in the conventional configuration, the air discharged from the upper outlet side cannot pass through the entire heat exchanger, or the air discharged from the lower outlet side cannot pass through the entire heat exchanger. Therefore, there has been a problem that the temperature distribution in the room becomes large depending on the operating state of the air conditioner.

  The present invention solves the above-described conventional problems, and an object thereof is to greatly improve the temperature distribution in the room regardless of the operating state.

  In order to solve the above-described conventional problems, the air conditioner of the present invention can be arbitrarily moved in the vertical direction inside the casing, and each wind of the cross flow fan installed vertically between the heat exchanger and the back of the chassis. It has a movable partition plate that partitions the road.

As a result, the area through which the air discharged to the upper and lower outlets is allowed to freely pass through the heat exchanger can be freely changed, thereby enabling an operation that can greatly improve the temperature distribution in the room.
Moreover, the air conditioner of this invention makes the movable partition plate shape which divides each air path of the crossflow fan installed up and down into a substantially circular arc shape.

  Thereby, since the water stop area on the back side inside the housing can be eliminated, aerodynamic characteristics can be improved, and energy saving of the air conditioner can be achieved.

  The air conditioner of the present invention can be operated to greatly improve the temperature distribution in the room because the area through which the air discharged to the upper and lower outlets passes through the heat exchanger can be freely changed according to the operating state. .

1st invention has a movable partition plate which can move arbitrarily in the up-down direction inside the case of an air conditioner, and partitions each air passage of a cross flow fan installed up and down between a heat exchanger and the back of a chassis Therefore, since the area through which the air discharged to the upper and lower outlets passes through the heat exchanger can be freely changed, the temperature distribution in the room can be greatly improved, and the comfort of the indoor unit installation space can be improved.

  In particular, the second invention has a substantially arcuate shape of the movable partition plate that partitions the air passages of the crossflow fans installed on the top and bottom of the air conditioner of the first invention. Since the water stop area on the side can be eliminated, aerodynamic characteristics can be improved, and energy saving of the air conditioner can be achieved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a schematic cross-sectional view of an air conditioner according to a first embodiment of the present invention.

  In FIG. 1, a suction port 11 is formed in the front surface of the chassis 10 and a blow-out port 15 is formed in the vertical direction of the suction port 11, and a heat exchanger 12 and condensed water condensed in the heat exchanger 12 are stored in the chassis 10. The drain pan 13 and the cross flow fan 14 connected to the motor in the vertical direction of the suction port 11 are respectively disposed. In the chassis 10, air discharged to the respective blowout ports 14 is connected to the heat exchanger 12. In order to change the area for heat exchange, the movable partition plate 21 is arbitrarily movable in the vertical direction.

  About the indoor unit of the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, indoor air flows into the chassis from the suction port 11 by operating the crossflow fan 14 that can be operated vertically.

  Furthermore, the movable partition plate 21 fixed at an arbitrary position changes the area where the air flowing out to the upper and lower outlets 15 exchanges heat with the heat exchanger 12 to supply refrigerant energy into the room.

  As described above, since the movable partition plate 21 can arbitrarily move in the present embodiment, the area through which the air discharged to the upper and lower outlets 15 passes through the heat exchanger 12 is freely changed depending on the operating state. By doing so, the temperature distribution in the room can be greatly improved, and the comfort of the indoor unit installation space can be improved.

  In addition, since the movable partition plate 21 has a substantially arc shape, the water stop area on the back side inside the chassis 10 can be eliminated, so that aerodynamic characteristics can be improved and energy saving of the air conditioner can be achieved. .

  As described above, since the air conditioner according to the present invention can improve the comfort of an air conditioner having a plurality of outlets, a plurality of outlets such as a floor-standing type air conditioner and a ceiling-type air conditioner are provided. It can be applied to various air conditioners.
