Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an air conditioner, and more particularly to an air conditioner capable of finely controlling an indoor temperature while having a simple structure.

[Conventional technology]

The conventional air conditioner has a structure as shown in FIG. 4 and FIG.

In FIG. 4, a cross flow fan 2 is provided laterally of the heat exchanger 1.
However, drain pans 3 are arranged below the heat exchanger 1, and the air heated or cooled by the heat exchanger 1 is sucked by the cross flow fan 2 and discharged to the outside.

Further, in FIG. 5, the drain pan 3, below the heat exchanger 1,
The sirocco fan 5 and the filter 6 are provided, and the air sent by the sirocco fan 5 is heated or cooled by the heat exchanger 1 and then discharged to the outside.

In addition, in FIG. 4 and FIG. 5, the arrow shows the flow direction of air.

[Problems to be solved by the device]

However, the air conditioner shown in FIG. 4 has the following problems.

Since the number of steps in the height direction of the heat exchanger is large, the number of welding points is large and the cost is high.

Since the air outlet is vertically long, it is difficult to maintain a uniform temperature distribution inside the room.

Since the cross-flow fan is installed on the downstream side (blowing side) of the heat exchanger, if the filter becomes clogged, drainage performance of the drain water will deteriorate.

Further, the air conditioner shown in FIG. 5 has the following problems.

Since the number of stages in the height direction of the heat exchanger is large, the number of welding points is large and the cost is high, as in the above case.

Since the air outlet is limited to only the upper part, it is difficult to make the temperature distribution in the room uniform. Further, if an outlet is also provided in the lower portion, it is necessary to dispose a duct from the outlet side of the heat exchanger to the lower outlet, which may increase the depth dimension (reference numeral d in the figure) of the air conditioner body. There is.

In order to improve the distribution of the air flow passing through the heat exchanger,
Although the heat exchanger must be inclined, this makes it difficult to reduce the depth dimension d of the air conditioner.

The present invention has been made to solve the above-mentioned various problems, and the purpose thereof is to reduce the cost, to easily achieve uniform temperature distribution in the room, and to improve drainage of drain water. It is to provide an air conditioner.

[Means for Solving the Problems]

In order to achieve the above object, an air conditioner of the present invention is a V-shaped heat exchanger in which a pair of flat fans are installed in the center of an air conditioner body and the air from the fans is heated or cooled. The air conditioner is provided below the fan and has a switching means for switching the flow direction of the air passing through the heat exchanger between upward and downward, and a partition wall that divides the air flow in the air conditioner body into left and right. It is configured to be provided in the central vertical direction of the machine body.

[Action]

According to the above configuration, the air blown from the fan is heated or cooled by the V-shaped heat exchanger, and then the flow direction is determined by the switching means. That is, if it is desired to blow out air from the upper outlet, the switching means causes the air to flow upward, and if it is desired to blow out air from the lower outlet, the switching means causes the air to flow downward.
Also, there is a pair of fans on the left and right, and the air conditioner body including that fan is completely separated on the left and right by the partition wall, so if you drive only one of the fans, the air will flow only to the right of the outlet. Or it will come out only from the left side.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

The air conditioner according to the present invention, as shown in FIGS. 1 and 2, has a flat fan 11 at the center of an air conditioner body 10.
Is fixed, and a V-shaped heat exchanger 12 is provided below the fan 11.
Is provided. Here, the flat-shaped fan 11 is formed to have a smaller thickness than the diameter of the blade or the casing, and the heat exchanger 12 has a small cross-sectional area and a small number of welding points. Dampers 13 as switching means are swingably attached to both sides of the heat exchanger 12 so that the flow direction of air coming from the heat exchanger 12 can be switched upward or downward. Above the damper 13 is an upper air passage 14
However, lower air passages 15 are formed below. The upper air passage 14 communicates with the upper outlet 16 and the lower air passage 15 communicates with the lower outlet 17. A drain pan 18 is provided below the heat exchanger 12. Further, a partition wall 19 is fixed between the fan 11 and the heat exchanger 12, between the heat exchanger 12 and the drain pan 18, and at the center of the upper outlet 16 and the lower outlet 17. Symbols in the figure
Reference numeral 20 indicates an air inlet. An external perspective view of the air conditioner is shown in FIG.

Next, the operation of this embodiment will be described.

The air sucked from the suction port 20 by the fan 11 is sent to the heat exchanger 12, heated or cooled by the heat exchanger 12, and then sent to the upper air passage 14 or the lower air passage 15 via the damper 13. To be In this case, if the damper 13 is in the position shown by the solid line in FIG. 1, the air from the heat exchanger 12 flows downward and flows out to the outside through the lower outlet 17 (indicated by the solid line arrow in the figure). Indicates the flow direction). Also, the damper 13
Is in the position shown by the chain double-dashed line in FIG. 1, the air from the heat exchanger 12 flows upward and flows out from the upper outlet 16 (in the figure, the direction of the air flow is indicated by the double-dashed line arrow). Indicates).
If the damper 13 is placed in the neutral position (horizontal position in FIG. 1),
Air can be blown out from both the upper outlet 16 and the lower outlet 17.

Further, by driving only one of the left and right fans 11, it is possible to blow air from only the right side or only the left side of the upper outlet 16 and the lower outlet 17. is there.

[Effect of device]

As described above in detail, according to the present invention, since the V-shaped heat exchanger with few welding points is installed, the cost can be reduced.

Further, since the switching means and the partition wall can freely blow the air upward or downward, rightward or leftward, it is possible to perform a fine control to even out the temperature distribution in the room. Can be maintained in a comfortable temperature state.

Furthermore, since the direction of the drain water drop that occurs in the heat exchanger during cooling is the same as the direction of the flow of the passing air, the drain water drainage is improved and the heat exchange performance of the heat exchanger is improved.
