The present invention relates to an air conditioner that switches between a vertical blowout and a vertical blowout.

[0002]

2. Description of the Related Art A conventional air conditioner is constructed as shown in FIGS. 10 and 11. In FIGS. 10 and 11, an indoor unit 21 of this air conditioner has air inside an indoor unit body 22. A partition plate 24 for forming the flow path 23 is provided, and an air suction port 25 is provided in front of the indoor unit main body 22 corresponding to an inlet of the air flow path 23. Heat exchanger 26 in air passage 23
And a blower 27 composed of a cross-flow fan or the like is provided in the air flow path 23 on the leeward side of the heat exchanger 26.

[0003] A horizontally elongated air outlet 28 is formed from the lower front portion to the bottom surface of the indoor unit main body 22 corresponding to the outlet of the air passage 23, and the blowing direction of the air blown out from the air outlet 28. Are provided in the air outlet 28 so as to be rotatable within the predetermined range of the air outlet 28. Each of the wind direction switching plates 29 is opposed to each other in parallel even when rotated. A drive motor (not shown) for rotating the wind direction switching plate 29 is provided at one end of each wind direction switching plate 29.

[0004] In the air conditioner having the two wind direction switching plates 29 configured as described above, when the room is to be cooled and heated, the room air is sucked from the air suction port 25 and the sucked air is sucked. Is passed through the air passage 23 and blows out from the air outlet 28, exchanges heat with the heat exchanger 26 when passing through the air passage 23, and blows the heat-exchanged air with the blower 27. The air is blown to the outlet 28. The direction of the air blown out from the air outlet 28 is blown into the room by changing the blowing direction within a predetermined range by rotating the two wind direction switching plates 29.

However, in the heating operation, the wind direction switching plate 29 is rotated vertically with respect to the bottom surface of the indoor unit main body 22 so as to blow the warm air blown out from the air outlet 28 to the lower part of the room. (Hereinafter, abbreviated as vertical blowing), but if the warm air is higher than room temperature, the warm air rises to the upper part of the room even if the warm air is blown from the air outlet 28 by the vertical blow. Therefore, there is a problem that the lower part of the room cannot be heated.

In order to solve the above-mentioned problems, a conventional air conditioner of this type is disclosed in, for example, Japanese Utility Model Publication No. 2-33071. Is configured as shown in FIGS. 12 to 14. In FIGS. 12 to 14, the indoor unit 31 of the air conditioner includes a heat exchanger 32 and a blower 33 composed of a cross flow fan or the like. An indoor unit main body 35 having an air flow path 34 is provided. The indoor unit main body 35 has a horizontally elongated air outlet 36 corresponding to the outlet of the air flow path 34 from the lower front surface to the bottom surface. .

Further, in the air outlet 36, the wind direction changing plate 37 which is selectively rotated is provided between a front and bottom, in FIG. 1. 4, for example, in the heating operation The state of vertical blowing (in the gazette, downward blowing) in which the wind direction switching plate 37 is set on the front side is illustrated.
According to this invention, on the front side of the air outlet 36,
Optionally auxiliary air outlet 38 without being closed by the wind direction changing plate 37 is formed, the said auxiliary air outlet 38 (in the publication, an auxiliary air Mukoan the plate) auxiliary wind direction changing plate 39 is It is provided to open and close freely.

[0008] The actual fair 2-33 constructed as described above
In the air conditioner disclosed in Japanese Patent No. 071, the auxiliary wind direction guide plate 3 is set in a state where the wind direction switching plate 37 is rotated to the front side during the heating operation.
9 open as in Fig. 1 4, most of the air fed by the blower 33 is blown toward the bottom surface side of the air outlet 36 to a vertical outlet, some of the air from the auxiliary air outlet 38 It is blown out toward the front. Since the warm air blown out from the auxiliary air outlet 38 is a relatively low-temperature warm air passing through the lower part of the heat exchanger 32 having a small heat exchange area, the warm air is blown out from the bottom of the air outlet 36. The warm air spreads to the lower part of the room so as not to rise to the upper part of the room but to be kept at a relatively low temperature from the auxiliary air outlet 38.

Further, in the cooling operation, as shown in FIG. 1 3, the wind direction changing plate 37 an auxiliary airstream direction guide plate 39 horizontally (hereinafter abbreviated as water Izuru Hirabuki.) With respect to the bottom surface of the indoor unit body 35 in it is rotated one in which it is sufficient to jar'll be blown cold air.

[0010]

However, in the case of an air conditioner having the two wind direction switching plates 29 constructed as described above, in the case of the heating operation, the air outlet 28 is required.
In order to blow the warm air blown out of the room to the lower part of the room, the warm air is blown by rotating the vertical air blow, and if the warm air is higher than room temperature, the warm air is blown from the air outlet 28 by the vertical blow. Even if it blows out, the warm air rises to the upper part of the room and there is a problem that the lower part of the room cannot be heated.

Further, in the air conditioner which solves the above-mentioned problems, during the cooling operation, the cool air blown from the blower 33 by the wind direction switching plate 37 and the auxiliary wind direction switching plate 39 is forcibly forced to horizontal discharge. In this case, the airflow direction is switched, so that airflow resistance is generated between the airflow direction switching plate 37 and the auxiliary airflow direction switching plate 39, and turbulence is generated. Resulting in. further,
In order to rotate the wind direction switching plate 37 and the auxiliary wind direction switching plate 39 in different directions, it is necessary to provide their own drive motors, so that the number of parts is increased and the cost is increased. In addition, there is a problem that the configuration for holding the horizontal and vertical blowouts is complicated.

The air conditioner of the present invention has solved the above-mentioned problems, and can perform comfortable cooling without reducing the amount of air blown from the air outlet during horizontal blowing. In addition, the temperature distribution in the room during the heating operation can be made uniform, the heating can be performed comfortably, and the horizontal and vertical blowing can be reliably performed with a simple configuration without increasing the cost. It is an object of the present invention to provide an air conditioner that can hold the air conditioner.

[0013]

In order to achieve the above object, an air conditioner according to the present invention is characterized in that the invention according to the first aspect is characterized in that the air blown out from an air outlet provided in an air conditioner body is provided. A wind direction switching plate that can change the direction by rotating the direction within a predetermined range; and an auxiliary wind direction switching plate that corrects the blowing direction of the wind direction switching plate by rotating the direction within the predetermined range. The wind direction switching plate and the auxiliary wind direction In an air conditioner in which the switching plate is rotated to switch the blowing direction between horizontal blowing and vertical blowing with respect to the bottom surface of the main body, the wind direction switching plate and the auxiliary wind direction switching plate are overlapped during the horizontal blowing. Holding means for holding the wind direction switching plate and the auxiliary wind direction switching plate at a predetermined interval at the time of the vertical blowing, and holding the wind direction switching plate and the auxiliary wind direction switching plate in a narrow state as the interval becomes leeward. It is provided.

A separating means for separating the wind direction switching plate from the auxiliary wind direction switching plate, and a pressing means for suppressing the separating force of the separating means.

[0015]

According to the present invention, in the first aspect of the present invention, in the case of horizontal blowing, the blower is configured such that the wind direction switching plate and the auxiliary wind direction switching plate are overlapped and held in an integrated state by the holding means. The blowing resistance generated by forcibly switching the blowing direction with the wind direction switching plate to the horizontal blowing from the cold air blown from the air is reduced to one sheet compared to two sheets, so it is blown out from the air outlet at the time of horizontal blowing Comfortable cooling is performed without reducing the air volume.

During vertical blowing, the wind direction switching plate and the auxiliary wind direction switching plate face each other at a predetermined interval by the holding means, and are held in a narrow state as the interval becomes leeward. Since the blowing speed of the warm air blown out from between the switching plate and the auxiliary wind direction switching plate is increased, the warm air blown out from the air outlet is diffused to a far area under the room, so that the room in the heating operation is The temperature distribution is made uniform,
Comfortable room heating is provided.

According to the second aspect of the present invention, in addition to the first aspect of the present invention, the driving force of the wind direction switching plate is connected by connecting the wind direction switching plate and the auxiliary wind direction switching plate by a connecting means. Since the auxiliary wind direction switching plate can be rotated at a low cost, the auxiliary wind direction switching plate is superimposed on the wind direction switching plate by pressing the separating force of the separating means with the pressing means during horizontal blowing. It is kept in one piece.

At the time of vertical blowing, the pressing means is released, and the wind direction switching plate and the auxiliary wind direction switching plate are separated by the separating force of the separating means. By opposing each other with a space therebetween and keeping the space narrower as the space becomes leeward, the horizontal blow and the vertical blow are reliably held with a simple configuration.
