Description

  The present invention relates to a vertical floor type air conditioner.

Conventionally, as shown in FIG. 14, a vertical floor type air conditioner has an air outlet at the upper part of the housing and an air inlet at the lower part (see, for example, Patent Document 1).
JP-A-6-101866

  However, in the above-described conventional configuration, there is one outlet at the upper part, and the blowing direction of the hot air and the cold air is such that the direction of the air can be changed by the wind direction splash. It was.

  This invention solves such a conventional subject, and it aims at providing the air conditioner which makes temperature distribution of the whole room uniform.

  In order to solve the above problems, the present invention provides an indoor unit in which a power supply plate, a heat exchanger, a blower, a plurality of air outlets, a switching means for the air outlets, and a suction port are arranged in a housing. A certain outlet is switched by switching means to blow out the air that has passed through the heat exchanger.

  With the above-described configuration, cold air and warm air are blown out from a plurality of air outlets, and a uniform temperature distribution is obtained.

  As is apparent from the above, the present invention is an indoor unit in which a power supply plate, a heat exchanger, a blower, a plurality of air outlets, a switching means for the air outlets, and a suction port are arranged in a housing. A certain outlet is switched by switching means to blow out the air that has passed through the heat exchanger. According to this configuration, the temperature distribution in the room can be made more uniform and the comfort can be improved.

  In addition, a plurality of outlets are switched depending on the operation mode, and according to this configuration, the temperature distribution in the room can be made more uniform and the comfort can be improved.

  In addition, the air outlet switching means is structured such that when one is closed, the other is released. According to this structure, the air outlet is switched with an inexpensive and simple structure, the temperature distribution in the room is made more uniform, and comfortable. It is possible to improve the performance.

  In addition, when the air outlet and the air inlet are arranged in the vicinity, they are structured not to be arranged on the same surface of the housing, and this structure prevents a short circuit where the blown air is immediately sucked. This makes it possible to make the temperature distribution in the room more uniform and improve comfort.

  In addition, a plurality of air outlets are arranged at the upper and lower parts of the housing, and equipped with means for switching between the upper and lower air outlets according to the operating state. By making this configuration, the temperature distribution in the room is more uniform. To improve comfort.

  In addition, it is provided with means for intermittently switching a plurality of air outlets, and by making this configuration, the temperature distribution in the room can be made more uniform and the comfort can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
1, 2, and 3 are configuration diagrams of the first embodiment. In FIG. 1, 1 is a power supply plate, 2 is a heat exchanger on the use side, 3 is a blower for sending cool / warm air, 4 is an outlet, 5 is an outlet switching panel, and 6 is an inlet.

  2 and 3 are views from above of the present embodiment, and by switching the blowing switching panel 5, the wind direction can be switched between front blowing and both side blowing.

  As described above, it is possible to improve the temperature distribution of the room by switching the front outlet and the both side outlets.

(Embodiment 2)
4 and 5 are configuration diagrams of the second embodiment. 4 and 5 are structural diagrams in which the outlet is blown up and down.

  And according to this embodiment, it becomes possible to improve the temperature distribution of the room by switching between the upper blowing during cooling, the lower blowing during heating, and the operation mode.

(Embodiment 3)
2 and 3 are configuration diagrams of the third embodiment. FIG. 4 is a structural diagram in which a switching means for the air outlet 4 is arranged as in FIGS. 2 and 3 and when one is closed, the other is released.

  And according to this embodiment, by switching a front blowing and a side blowing with the switching panel 5, it becomes possible to switch a front blowing and a left-right blowing, and to improve the temperature distribution of a room.

(Embodiment 4)
6 and 7 are structural diagrams of the fourth embodiment. By arranging the suction port 6 and the blower port 4 on different planes as shown in the figure, it is possible to prevent a short circuit in which the blown wind is sucked.

  And according to this embodiment, since the short circuit in which the warm air of the lower blowing 4 at the time of heating is sucked in from the suction inlet 6 of the vicinity can be prevented, it becomes possible to improve the temperature distribution of a room.

(Embodiment 5)
FIG. 8 is a room temperature change characteristic diagram at the time of heating start-up according to the fifth embodiment. FIG. 9 is a room temperature change characteristic diagram at the time of heating start-up with only the upper blowout. FIG. 10 is a room temperature change characteristic diagram at the time of heating start-up with only the lower blowout. When comparing these characteristic diagrams, as shown in FIG. 8 of this embodiment, only the upper blowing is performed until a certain rise time or a certain temperature is reached, and then the lower blowing is performed. A very comfortable space can be realized.

(Embodiment 6)
FIG. 11 is a plane distribution diagram of room temperature when the front blowing as shown in FIG. 2 of the sixth embodiment and both side blowings as shown in FIG. 3 are periodically switched. FIG. 12 is a plane distribution map of room temperature with only front blowing. FIG. 13 is a plane distribution diagram of room temperature only for both side blowing. Comparing this figure clearly shows that a large area is more comfortable when the front blowout and both side blowouts are switched periodically.
