FIG. 2 is a state where an opening of a wind shielding member is opened as a first embodiment. FIG. 3 is an explanatory view of the air conditioner according to the present invention, and is a cross-sectional view showing a state in which the opening of the wind shield member is shielded. FIG. 5 is a perspective view showing a state where an opening is shielded, FIG. 5 is an exploded perspective view of a main part of an air conditioner shown as Example 1, and FIG. 6 is an explanatory view of a main part of the air conditioner shown as Example 1. Fig. 7A is a sectional view showing an opening of the wind shielding member and an opening / closing member that opens and closes the opening slidably. FIG. 8 is a perspective view showing a state in which the opening of the wind shielding member is opened as 2, and FIG. Is a perspective view showing the in which state.

  As shown in FIG. 1 to FIG. 4, the air conditioner according to the present invention has an air passage connecting an inlet 1 provided at the upper part of the main body and an outlet 2 provided at the lower part, as shown in FIGS. It has a configuration in which a heat exchanger 4 including a first heat exchanger 4a and a second heat exchanger 4b that are separated from each other in the front-and-rear direction with a separation portion 3 and a blower fan 5 are provided.

  The spacing portion 3 is provided with a wind shielding member 7 having an opening 6, and the wind shielding member 7 is provided with an opening / closing member 8 for slidably opening and closing the opening 6 of the wind shielding member 7. ing.

  The air sucked from the suction port 1 passes through a filter 15 provided so as to face the suction port 1, and is then subjected to heat exchange by the heat exchanger 4 or sucked air. After a part of the air flows through the opening 6 of the shielding plate 7, the air is mixed with the air heat-exchanged by the heat exchanger 4 and sent out to the outlet 2 by the blower fan 5. .

  A part of the air sucked from the suction port 1 is mixed with the air heat-exchanged by the heat exchanger 4 after passing through the opening 6 of the shielding plate 7, thereby improving the cooling capacity during the cooling operation. Raises the blowing temperature without lowering the temperature, prevents over-cooling, and improves comfort.

  The opening 6 of the shielding plate 7 is slidably opened and closed by the opening and closing member 8, and a suitable ventilation amount can be obtained by adjusting the opening degree according to the sliding amount of the opening and closing member 8. It is like that.

  And since the said opening-and-closing member 8 is comprised so that it may slide in a horizontal direction, when opening and closing the opening 6 of the said shielding board 7, as a space required to slide, it was attached rotatably, for example As in the case of the opening / closing member, the upper portion of the wind-shielding member is not largely occupied as a rotation range.

  As a result, there is no need to ensure a large gap between the opening 6 of the shielding plate 7 and the filter 15 provided on the inside of the suction port 1 above the opening 6. The configuration can contribute to downsizing.

  Next, the configuration and operation of the opening / closing member 8 that slidably opens and closes the opening 6 of the shielding plate 7 will be described with reference to the accompanying drawings.

As shown in FIG. 5, FIG. 6 (A), and FIG. 6 (B), the opening / closing member 8 slides when the drive motor 9 is linked.
In the drive motor 9, a shaft hole 10 a of a drive gear 10 is fitted to a drive shaft 9 a of the drive motor 9, and a leg portion 9 b of the drive motor 9 is provided on a support 11 that supports the drive motor 9. The screw holes 11b are fixed by screwing. At this time, the tip end portion of the drive shaft 9a fitted in the shaft hole 10a of the drive gear 10 is rotatably supported by a support hole 11a provided in the support tool 11.

  The support 11 is attached by screwing a screw (not shown) through an attachment hole 11c provided in the support 11 to an attachment 7a protruding from the side of the shielding plate 7. It has become.

  The shield plate 7 is provided with a groove portion 7b in which both sides of the linkage shaft 13 having linkage gears 12 are rotatably accommodated, and the linkage shaft 13 accommodated in the groove portion 7b is detachably held. A holding piece 14 is provided.

  The holding piece 14 is configured to have the same height as the flange 6a formed on the periphery of the opening 6 of the shielding plate 7, and the opening and closing are provided above the holding piece 14 and the flange 6a. The member 8 can be installed in such a manner that it can be received in a wide range and can slide smoothly without rattling.

  Further, when the opening / closing member 8 is installed above the holding piece 14 and the flange 6a, as shown in FIG. 6 (A), the driven gear 8a continuously formed on both sides of the opening / closing member 8 has the linkage. In order to mesh with the gear 12 and to prevent the meshed driven gear 8a from separating from the linkage gear 12, the upper end of the support 11 is opposed to the upper surface portions on both sides of the opening / closing member 8. The horizontal portion is provided.

  With the above-described configuration, as shown in FIGS. 6A and 6B, by driving the drive motor 9, the linkage gear is engaged via the linkage gear 12 meshed with the drive gear 10. The driven gear 8a meshed with the gear 12 is driven, and the opening / closing member 8 having the driven gear 8a is moved from the position of the solid line shown in FIG. The opening 6 of the shielding plate 7 can be opened at a predetermined opening degree.

  Accordingly, when it is desired to open the opening 6 of the shielding plate 7, the opening / closing member 8 is slid forwardly of the first heat exchanger 4a as shown in FIGS. When the opening 6 of the shielding plate 7 is desired to be shielded, the opening / closing member 8 can be accurately shielded by sliding it to the shielding position as shown in FIGS. It becomes like this.

  At that time, as described above, as a space necessary for sliding, for example, the upper part of the wind shield member 7 is largely occupied as a rotation range, such as an opening / closing member that is rotatably attached. Therefore, it is not necessary to secure a large gap between the opening 6 of the wind shielding member 7 and the filter 15, and the air conditioner can be miniaturized.

  Further, a portion of the wind shield member 7 that overlaps the heat exchanger 4 is provided with a through hole 7e, so that the intake air from the suction port 1 flowing through the through hole 7e is sucked by the heat exchanger 4. Heat is exchanged.

When the opening 6 is opened by the opening / closing member 8, the through hole 7 e is simultaneously shielded by the opening / closing member 8, thereby reducing the amount of ventilation to the heat exchanger 4. The dehumidifying performance can be increased by reducing the amount.
When the through-hole 7e is shielded by the opening / closing member 8, the through-hole 7e does not need to be completely sealed, and there is no problem even if there is air circulation at the location.

  In the first embodiment described above, the opening / closing member 8 is configured to slide in the front-rear direction of the heat exchanger 4 as shown in FIGS. 7 and FIG. 8, the heat exchanger 4 may be configured to slide in the left-right direction.

  In this case, as shown in FIGS. 7 and 8, the arrangement of the drive motor 9, the linkage gear 12, the driven gear 8a, and the like is changed by approximately 90 degrees with respect to the configuration of the first embodiment described above, and the shielding is performed. While the wind shield 7c and the opening 7d are alternately arranged in the longitudinal direction of the wind member 7, the longitudinal opening of the opening / closing member 8 corresponds to the auxiliary opening 8c and the opening 7d corresponding to the wind shield 7c. It is only necessary to provide auxiliary wind shields 8b to perform.

  Accordingly, when opening the opening 6, the auxiliary wind shield 8 b of the opening / closing member 8 is superposed on the wind shield 7 c of the wind shield 7 by being driven by the drive motor 9 as shown in FIG. 7. The opening / closing member 8 may be slid to a position where the auxiliary opening 8c communicates with the opening 7d of the wind-shielding member 7.

  Further, when the opening 6 is shielded, the auxiliary opening 8c of the opening / closing member 8 is superposed on the wind shield 7c of the wind shield 7 by being driven by the drive motor 9 as shown in FIG. The opening / closing member 8 may be slid to a position where the auxiliary wind shield 8b overlaps the opening 7d of the wind shield 7.

  Further, as shown in FIGS. 2, 4, 7 and 8, the drive motor 9 is arranged at the side of the heat exchanger 4, thereby the suction air. When the air sucked from the mouth 1 goes to the heat exchanger 4 or the wind shield member 7, it does not go to the heat exchanger 4 or the wind shield member 7 after hitting the drive motor 9.

  Therefore, the drive motor 9 does not become an air resistance that impairs the blowing performance in the air passage connecting the suction port 1 and the blowout port 2.

  In addition, when the drive motor 9 has heat, there is a possibility that dew condensation may occur due to the air sucked into the drive motor 9, but the drive motor 9 is connected to the heat exchanger 4. By arranging it on the side, condensation is not caused by these causes.
