Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fitting portion structure of an air conditioner, which is improved in a connecting portion between an air conditioning duct and a louver casing.

[0002]

[Prior Art]

 Conventionally, as shown in FIGS. 4 and 5, an instrument panel 1 of an automobile is provided with an air conditioning ventilator 2 for distributing cold or warm air to a driver's seat and a passenger's seat. As shown in FIG. 6, the ventilator 2 includes a connecting louver 3 and a horizontal louver 4 that control the flow direction of the wind, and a louver casing 5 that surrounds the connecting louver 3 and the horizontal louver 4. The connecting louver 3 controls the left and right flow direction of the wind, and the horizontal louver 4 controls the up and down flow direction of the wind. The louver casings 5 are separately provided on the left and right sides of the instrument panel 1, and the coupling louvers 3 inside the louver casing 5 can also be operated independently on the left and right sides, so that the wind on the left and right louver casings 5 can be prevented. The directions can be set separately.

The connecting louvers 3 for controlling the left and right flow directions of the wind are connected by a connecting bar 7 so that a plurality of (in this case, three left and right) vertical louvers 6 that can be independently rotated can be integrally rotated. It is connected and can be rotated by an operation knob 8 (see FIG. 5) provided at the air outlet to control the flow direction of the air. The rear side of the louver casing 5 in which the connecting louver 3 is arranged is fitted and connected to the air conditioning duct 9. The louver casing 5 and the air-conditioning duct 9 are connected to each other by straight portions extending straight from each other. In addition, W in the figure indicates the wind for air conditioning.

As a ventilation device for an automobile, there is one disclosed in Japanese Patent Publication No. 61-217643. What is disclosed in this publication is a louver case in which the leg shape is inclined outward.

[0005]

[Problems to be solved by the device]

 However, since the structure of the fitting portion between the conventional louver case and the air conditioning duct having such a configuration is made by the straight straight portions of both, the operation knob is operated to set the wind direction to the driver seat and When directed toward the passenger side, the wind whose direction is changed by the connecting louver and the straight extending portion of the fitting portion of the louver casing and the air conditioning duct interfere with each other as shown in Part A of FIG. However, there was a problem that the air flow rate was lost and noise was generated due to interference. The automobile ventilation device disclosed in Japanese Patent Publication No. 61-217643 avoids interference of wind in the casing, but the louver is rotatable in all directions in which the center is held. Therefore, if one of the louvers is tilted outward, that part will be located on the back side, and the wind will not be refracted on average.

The present invention has been made to solve the above-mentioned problems of the conventional one, and the shape of the fitting portion between the louver casing and the air conditioning duct was improved to prevent the loss of air volume and noise. An object is to provide a fitting portion structure for an air conditioner.

[0007]

[Means for Solving the Problems]

 As a means for solving the above-mentioned conventional problems, the present invention forms a connection louver by connecting one end of a plurality of vertical louvers for controlling the flow direction of wind and rotating integrally. In an air conditioner in which an installed louver casing is connected to an air conditioning duct, the side wall portion of the louver casing and the side wall portion of the air conditioning duct fitted with the side wall portion are respectively formed on the inclined surfaces facing outward of the connecting louver. It is characterized in that the inclined portions are formed in parallel with each other, and the inclined portion of the side wall portion of the air conditioning duct and the inclined portion of the side wall portion of the louver casing are fitted and connected.

[0008]

[Action]

 As described above, the present invention forms the side wall portion of the louver casing and the side wall portion of the air conditioning duct into which the side wall portion fits into an inclined portion that is parallel to the outwardly inclined surface of the connecting louver. Since the slanted portion of the side wall of the duct for use and the slanted portion of the side wall of the louver casing are fitted and connected to each other, the connected portion also becomes an outwardly inclined surface. Therefore, even if the connected louver in the louver casing has an outwardly inclined surface, the wind flowing along the connected louver will hit the outwardly inclined surface of the part where the louver casing and the air conditioning duct are connected. There is no. That is, the wind flowing along the connecting louver and the side wall of the louver casing do not interfere with each other.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The same members as those in FIGS. 4 to 6 are designated by the same reference numerals in the following description. What is shown in FIG. 1 is a cross-sectional view of the left and right louver casings 5. Inside the two louver casings 5 on the left and right, three vertical louvers 6 for controlling the flow direction of the wind are attached rotatably by threes. The end of the vertical louver 6 on the back side is connected by a connecting rod 7 to form a connecting louver 3 which rotates integrally. Further, the air outlet side of the vertical louver 6 in the middle of the left and right is connected to an operating knob 8 slidably provided on the horizontal louver 4 on the air outlet side.

Therefore, by moving the operation knob 8 to the left and right, the three vertical louvers 6, that is, the connecting louvers 3 can be integrally rotated in the same direction on the left and right to change the direction of air flow. (See Figure 2). Since the left and right louver casings 5 of the connecting louver 3 can be rotated separately, the flow direction of the wind can be set separately for the left and right. The side wall 5a of the louver casing 5 and the side wall 9a of the air-conditioning duct 9 into which the side wall 5a of the louver casing 5 fits are inclined with respect to each other in parallel to the outwardly inclined surface of the connecting louver 3. Is formed in the part. The louver casing 5 and the air conditioning duct 9 thus formed are connected by fitting the inclined portion 5a of the louver casing 5 and the inclined portion 9a of the air conditioning duct 9 into each other.

As described above, according to the present invention, the side wall portion 5a of the louver casing 5 and the side wall portion 9a of the air conditioning duct 9 to which the side wall portion 5a fits are parallel to the outwardly inclined surface of the connecting louver 3. The sloping portion 9a of the air conditioning duct 9 is connected to the sloping portion 9a of the air conditioning duct 9 by fitting the sloping portion 5a of the louver casing 5 to each other. It flows into the louver casing 5 through the combined connecting portion, is divided in the direction by the connecting louver 3, and is blown out from the air outlet.

At this time, even if the connecting louver 3 in the louver casing 5 is an outwardly inclined surface, the side wall portion 5a of the louver casing 5 and the side wall portion 9a of the air conditioning duct 9 into which the side wall portion 5a is fitted. Is an inclined portion parallel to the outwardly inclined surface of the connecting louver 3, so that the wind W flowing along the connecting louver 3 does not hit the inclined portion of the louver casing 5. That is, the wind W flowing along the connecting louver 3 and the side wall portion 5a of the louver casing 5 do not interfere with each other.

[0013]

[Effect of the device]

 As described above, the present invention forms the side wall portion of the louver casing and the side wall portion of the air conditioning duct into which the side wall portion is fitted into the inclined portion parallel to the outwardly inclined surface of the connecting louver. Since the inclined portion of the side wall portion of the air conditioning duct and the inclined portion of the side wall portion of the louver casing are fitted and connected to each other, the connected portion also becomes an outwardly inclined surface. Therefore, even if the connecting louver in the louver casing is inclined outward, the wind flowing along the connecting louver and the side wall of the louver casing do not interfere with each other. Since the interference is eliminated in this way, the loss of the blown air volume is eliminated and the noise due to the interference is eliminated.
