Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly, to an air conditioner having a sliding door for changing the flow of air flowing in a duct.

[0002]

2. Description of the Related Art Conventionally, an air conditioner has been proposed in which the flow of air is changed by using a loop-shaped film damper 1 as shown in FIGS. That is, duct 2
The air introduced from the upstream of the heater is heated by the heater core 3,
The amount of air supplied to the heater core 3 is controlled by the air mixing door 4, and the air whose heating amount is controlled in this way is blown out from the defroster outlet 5, the vent outlet 6, and the heater outlet 7. I have to. In this case, the film damper 1 has a substantially rectangular loop shape on the inner surface of the duct 2 and along the defroster outlet 5, the vent outlet 6, and the heater outlet 7. As shown in FIG. And driven by the drive roller 9.

An opening 10 and an opening 11 are provided in the film damper 1. Each opening 10, 11 is provided with a longitudinal bridge 12, 13. Therefore, according to such a configuration, the loop-shaped film damper 1 is transported by the drive roller 9 so that the openings 10, 1 can be moved.
The air 1 blown out from each of the outlets 5, 6, 7 by changing the opening area for each of the outlets 5, 6, 7
The amount of 4, 15, 16 can be controlled.

In this case, as disclosed in JP-A-64-85809, when the film damper 1 is transported in the direction of arrow F shown in FIG. The edge 17 is formed in a V-shape so as not to be caught by the end 18 of the opening 6, and the center side thereof is formed so as to be separated from the front end 18 of the opening 10.

At this time, the edge portion 17 The ends 17a, 17a first pass under the end portion 18 in proximity to the end portion, and the central portions 17b, 17b pass through the rear portion, so that there is no possibility that the edge portion 17 is caught by the end portion 18.

[0006]

However, conventionally, it is possible to control the amount of air blown from the defroster outlet 5, vent outlet 6, and heater outlet 7 using the film damper 1. When the present invention is applied to a door for adjusting the heating ratio between the cool air cooled by the evaporator and the warm air heated by the heater core 3 from the upstream side of the duct 2, the air flowing in the duct for introducing and leading the air is used. Since it is opposed to the right angle direction, when a film is used for such a type of door, since a film-like member is used, a complicated mechanism and space are required for film winding, and Since the film is deflected, it is not possible to accurately adjust the mixing ratio of the cool air and the warm air. Therefore, a tension mechanism for eliminating the warp is also required.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and controls the flow of air introduced and discharged into a duct by using a slide-type door. To prevent smooth movement of the sliding door by preventing it from being caught between the sealing surface of the guide portion for guiding the sliding door and miniaturization by using the sliding door. .

[0008]

According to the first aspect of the present invention, there is provided a sliding type door which is transported while maintaining a direction substantially perpendicular to the flow of air, and a guide portion which faces this end. The edge of the sliding door is formed so that the center side is gradually separated from the edge of the sealing surface, so that the edge of the sliding door does not catch on the edge of the sealing surface, so that the sliding door can move smoothly. .

In this case, the sliding type door moves in a direction perpendicular to the flow of air, and is not a type in which the rotating angle changes as in the conventional air mixing door, so that the sliding angle is maintained. Space can be made unnecessary, so that the size of the air conditioner itself can be reduced.

According to the second aspect of the present invention, one or both of the sliding direction end of the sliding door and the edge of the sealing surface are formed into a V-shape or a shape close to the V-shape. Therefore, an air conditioner having a sliding door as a main configuration can be realized.
