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: This air conditioner comprises a mechanism capable of moving the upper and lower end parts of panel fitted to a suction port to a front side. Accordingly, not only the amount of the air discharged to the upper and lower blowout ports but also the areas allowing the air to be passed in the heat exchanger 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. 3 is a schematic cross-sectional view of a conventional air conditioner described in the patent literature.

As shown in FIG. 3, 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 in 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. For this reason, there is a problem that the temperature distribution in the room becomes non-uniform 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 operation state.

  In order to solve the above-described conventional problems, the air conditioner of the present invention has a mechanism in which the upper and lower ends of the panel provided at the suction port can move to the front side.

  As a result, not only the amount of air discharged to the upper and lower outlets but also the area to be passed through the heat exchanger can be changed, thereby enabling an operation that can greatly improve the temperature distribution in the room.

  Moreover, the air conditioner of this invention has a movable partition plate which can move to the upper-lower-end part of a heat exchanger in the air path inside a chassis.

  Thus, by changing the opening of the movable partition plate according to the operating state, not only can the amount of air discharged from the upper and lower outlets be controlled, but the amount of air sucked into the air conditioner can be changed in the vertical direction. Therefore, it is possible to perform an operation that can greatly improve the temperature distribution in the room.

The air conditioner of the present invention has a mechanism in which the upper and lower ends of the panel provided at the suction port can move to the front side according to the operating state, so that the amount of air discharged to the upper and lower outlets Not only can the area that is passed through the heat exchanger be changed, but operation that can greatly improve the temperature distribution in the room becomes possible.

  In addition, since the amount of blown air can be changed by providing a swinging damper inside the housing and making its free end substantially contact the upper and lower ends of the heat exchanger, the temperature distribution in the room can be greatly improved.

  Since the first invention has a mechanism in which the upper and lower ends of the panel provided at the air inlet of the air conditioner can move to the front side, not only the amount of air discharged to the upper and lower outlets, Since the area to be passed through the heat exchanger can also be changed, an operation that can greatly improve the temperature distribution in the room becomes possible.

  The second invention has a movable partition plate swinging in the back of the heat exchanger, and the amount of air discharged from the upper and lower outlets is changed by changing the opening of the movable partition plate according to the operating state. Not only can it be controlled, but the amount of air sucked into the air conditioner can be varied in the up-and-down direction suction amount, so that an operation that can greatly improve the temperature distribution in the room becomes possible.

  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 arranged, and the movable upper and lower ends of the panel provided at the suction port 11 have a mechanism that can move to the front side. The panel 21 is configured.

  About 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.

  Further, the upper and lower ends of the panel provided in the suction port 11 are moved forward by an arbitrary distance from the chassis 10 by moving the movable panel 21 having a mechanism capable of moving to the front side. Not only the amount of air to be discharged but also the area to be passed through the heat exchanger 12 is changed to supply refrigerant energy into the room.

  As described above, since the upper and lower ends of the movable panel 21 can arbitrarily move forward in the present embodiment, not only the amount of air discharged to the upper and lower outlets 15 depending on the operating state, but also the heat. Since the area passed through the exchanger 12 can also be changed, the temperature distribution in the room can be greatly improved, and the comfort of the indoor unit installation space can be improved.

(Embodiment 2)
FIG. 2 is a schematic cross-sectional view of an air conditioner according to the second embodiment of the present invention.

  In FIG. 2, it is comprised from the movable partition plate 22 which can move to the upper-lower-end part of the heat exchanger 12 in the air path inside the chassis 10. As shown in FIG.

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

  First, in the air passage inside the chassis 10, the movable partition plates 22 that are movable at the upper and lower ends of the heat exchanger 12 are provided, so that not only the amount of air discharged from the upper and lower outlets 15 can be controlled, but also the air conditioner Since the amount of air sucked into can be changed in the vertical direction, an operation that can greatly improve the temperature distribution in the room becomes possible.

  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.
