ものもある。Conventional technology The cowl box for automobiles is known, for example, from Japanese Patent Application Laid-Open No.
As shown in Japanese Patent No. 11978, it serves as a strength member for the front waist portion of the vehicle body and at the same time functions as an outside air intake portion of the vehicle air conditioning unit. Since rainwater and car wash water also flow into this cowl box, a water outlet is formed on the cowl side to allow the inflow water to quickly drain to the outside. Some of them have a one-way valve opened by water pressure placed in the water outlet to prevent splashes and the like from entering the cowl box through the water outlet.

ものである。Problems that the invention aims to solve If the water outlet is open, the ram pressure inside the cowl box will drop, so even if you want to increase the air volume, the maximum air volume will be suppressed to a low level. In addition, with a one-way valve at the water outlet, there is no escape of ram pressure in the cowl box, so although there is no reduction in the maximum air volume, the minimum air volume tends to increase, and in either case, the air It is not possible to match the air volume adjustment by operating the air volume adjustment lever of the harmonization unit with the actual introduced air volume. Therefore, the present invention provides a cowl box structure for an automobile that can match the air volume adjustment using the air volume adjustment lever described above with the actual air volume introduced, thereby achieving appropriate air conditioning.

弁本体６ｂを全閉させるようになつている。 In FIGS. 1 to 3, reference numeral 1 denotes a cowl box composed of a dash top panel 2, a cowl top panel 3, and a cowl side panel 4. A water-trapping recess 2a is formed in the cowl side panel 4, and a cutout 4a is formed in the cowl side panel 4 to form a water drain port 5. Reference numeral 6 denotes an on-off valve made of an elastic material such as rubber or resin provided in the water drain port 5, and is composed of a base portion 6a and a valve body 6b integrally molded with the base portion 6a.
There is a vertical slit 6 in the center from the lower edge.
c to make it easy to elastically deform.
This opening/closing valve 6 is fixed to the inner surface of the cowl side panel 4 with the base portion 6a and screws, etc., and is opened when the valve body 6b is elastically deformed inside the cowl box 1. I'm starting to do that. Reference numeral 7 denotes a valve operating means that opens and closes the on-off valve 6 in conjunction with an air volume adjustment lever 11 of a vehicle-mounted air conditioning unit (not shown). This valve operating means 7 includes a guide member 8 joined to the outer surface of the cowl side panel 4.
It consists of a handle 9 with an L-shaped side surface that is held by the valve body 6b to open and close the valve body 6b, and a push-pull cable 10 connected to the upper end of the handle 9 and the end of the air volume adjustment lever 11. ing.
The tip of the handle 9 is in contact with the outer surface of the valve body 6b, and the air volume adjustment lever 11 is moved to the fan stop position.
That is, at the "0" position of the air volume display on the lever unit case 12, the push-pull cable 10 is indexed to the maximum, the handle 9 is pulled up to the upper limit position, and the valve body 6b is held fully open. By operating the air volume adjustment lever 11 in the direction of increasing the air volume, that is, in the direction of "1", "2", "3", or "4" on the air volume display, the handle 9 is activated by pushing the push/pull cable 10. By moving the handle 9 downward, the valve body 6b is moved back in the valve closing direction by its own elasticity, and at the maximum air volume "4" display position, the handle 9 is moved down to the lower limit position to fully close the valve body 6b. There is.

る。 According to the above embodiment structure, the air volume adjustment lever 1
1 is at the fan stop position with an air volume of "0", the handle 9 is pulled up to the upper limit position by the push-pull cable 10, and the valve body 6b of the on-off valve 6 is fully open. When the air volume adjustment lever 11 is operated in the direction of increasing the air volume, the handle 9 is moved down by the push/pull cable 10 in conjunction with this, and the valve body 6b is operated in the valve closing direction by its own elasticity. At the "1" and "2" positions, where the valve body 6b has a small amount of water, the closed position of the valve body 6b is regulated by the handle 9, and the water drain port 5 remains open, so that the ram pressure inside the cowl box 1 increases. Therefore, a low air volume necessary for air conditioning can be obtained. Also, set the air volume adjustment lever 11 to "3".
When you want to obtain a slightly larger air volume by adjusting the position,
The valve body 6b can close to a position close to fully closed under the control of the handle 9, increasing the ram pressure in the cowl box 1, and then moving the air volume adjustment lever 11 to the maximum air volume "4". When you operate the position,
Since the valve body 6b is in the fully closed position and completely closes the water outlet 5, the ram pressure within the cowl box 1 increases and a desired maximum air volume can be obtained.

きるという実用上多大な効果を有する。Effects of the invention As described above, according to the invention, the opening degree of the on-off valve provided at the water outlet on the side of the cowl box is adjusted by the valve operating means in conjunction with the operation of the air volume adjustment lever. Since the ram pressure can be adjusted, it is possible to match the air volume adjustment by operating the air volume adjustment lever with the actual introduced air volume, providing comfortable air conditioning, and improving quality and reliability. This has a great practical effect in that it can further improve the performance.
