[Structure] An injector that can be opened and closed is attached to the air conditioning outlet, and the opening and closing degree of the injector is adjusted according to the air volume, so the air conditioning outlet can be hidden visually when not needed. The degree of freedom can be increased, and the injector can be hopped up when necessary.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hop-up air conditioner.

[0002]

[Prior Art]

 As shown in FIG. 2, the instrument panel 01 of the vehicle is provided with a meter 03 and a plurality of air conditioning outlets 02 are opened, and these air conditioning outlets 02 are connected to a duct (not shown), Natural, cold or warm air is blown out. Here, the conventional air-conditioning air outlet 02 is always open, and its size, shape, arrangement, etc. are designed so that the maximum air volume can be provided to the occupant. For this reason, the air-conditioning outlet 02 is located in an obtrusive position on the instrument panel 01 and has a relatively large opening.

[0003]

[Problems to be solved by the device]

 As described above, the conventional air-conditioning air outlet 02 is always open and has a relatively large opening, which limits the degree of freedom in design. Therefore, the air-conditioning outlet 02 may not match the image of the vehicle. The present invention has been made in view of the above conventional technique, and an object of the present invention is to provide a pop-up type air conditioner which is visually superior and whose opening degree can be adjusted according to the air volume.

[0004]

[Means for Solving the Problems]

 The present invention that achieves such an object is an air conditioner in which an air conditioning outlet opening in an instrument panel of a vehicle and an air conditioning fan are connected via a duct, and the air volume of the air conditioning fan is controlled by an air conditioning circuit. A hop-up drive mechanism that rotatably supports the injector that covers the air-conditioning air outlet from one end side and lifts the other end side of the injector is installed. A pop-up control circuit for controlling an up drive circuit to automatically adjust the opening / closing degree of the injector is provided.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of the present invention. As shown in the figure, the air conditioning outlet 2 that opens in the instrument panel 1 is connected to an air conditioning fan (not shown) via a duct 3 so that natural air, cold air, or warm air can be blown out. Has become. The air volume of the air-conditioning fan is controlled by the air-conditioning circuit 4 according to an instruction from the passenger. The air conditioning outlet 2 is covered by an injector 5 so as to be openable and closable, and one end of the injector 5 is pivotally attached to the instrument panel 1 by a pin 6. The injector 5 is a tubular outlet that is connected to the duct 3. The injector 5 can open and close the air conditioning outlet 2 by rotating around the pin 6, and the opening and closing degree depends on the angle of rotation. Can be adjusted.

A hop-up drive mechanism for lifting the injector 5 from the other end side and rotating the injector 5 around the pin 6 is also installed. In this hop-up drive mechanism, a rack 7 is connected to the other end of the injector 5, a pinion 8 is meshed with the rack 7, and a motor 9 for driving and rotating the pinion 8 is provided. Therefore, by driving and rotating the pinion 8 by the motor 9 and moving the rack 7 up and down in the figure, the injector 6 can be lifted from the other end side. Further, a hop-up control circuit 10 is provided for automatically controlling the hop-up drive mechanism according to the air volume of the air conditioning fan. The hop-up control circuit 10 controls the motor 9 to increase the opening / closing degree of the injector 5 as the air volume of the air conditioning fan is adjusted by the air conditioning circuit 4.

Therefore, when the air volume of the air conditioning fan is maximum, the opening / closing degree of the injector 5 is maximized, and a large air volume from the air conditioning fan is smoothly blown out from the air conditioning outlet 2 opened by the injector 5. become. Further, when the air volume of the air conditioning fan is medium, the opening / closing degree of the injector 5 becomes medium, and when the air conditioning fan is stopped, the injector 5 closes the air conditioning outlet 2. In addition, inside the injector 5, an inner lid 11 that guides the ventilation from the duct 3 to the air conditioning outlet 2 is provided. The inner lid 11 is configured to expand and contract automatically depending on the opening / closing degree of the injector 5. Therefore, since the airflow from the duct 3 is guided to the air conditioning outlet 2 by the inner lid 11, even if the injector 5 is opened and closed, the airflow from the duct 3 does not leak.

In the hop-up type air conditioner of the present embodiment having the above configuration, the injector 5 can open and close the air conditioning outlet 2 according to the air volume from the air conditioning outlet 2. Therefore, when the air volume from the air conditioning outlet 2 is not needed, the air conditioning outlet 2 can be visually turned off by closing the air conditioning outlet 2 with the injector 5, and the air conditioning outlet 2 Only when a required air volume is required, the opening / closing degree of the injector 5 can be adjusted to guide the required air volume. Therefore, the degree of freedom in designing the air conditioning outlet 2 in the design of the instrument panel 1 is increased, and the instrument panel suitable for the image of the automobile can be provided.

Although the pop-up drive mechanism is composed of the rack 7 and the pinion 8 in the above-mentioned embodiment, the pop-up drive mechanism is not limited to this, and may be another structure capable of opening and closing the injector 5. good. Further, it is preferable that the air conditioning outlet 2 is provided with a louver or the like for adjusting the wind direction.
