Abstract

PURPOSE:To extremely facilitate insertion and securing of a blow-off grill, by a method wherein, in a mounting structure for blow-off grill of an air conditioner for vehicle, an elastic seal member is mounted to a blow-off opening in a ventilating duct. CONSTITUTION:A seal member 20 engages a blow-off opening part 5 of a defroster duct 1 in a manner to cover the duct, and side edges 21 and 22 are adhered to the upper surface of the defroster duct 1. The seal member 20 is of a laminar material, such as synthetic resin materials, having elasticity, and a slit 23 is provided in a longitudinal direction of a rising edge 5a of a blow-off opening 5 to form two lip parts 24, 24 positioned facing and opposite to each other. When a mating part 10 of a blow-off nozzle 5 is inserted into the blow-off opening 5, the lip parts 24 are bent downward by the mating part 10, the elasticity normally brings the lip parts into contact with the mating part 10, and this enables closing of a gap 12 between the mating part 10 and the opening 5.

Description

[Detailed description of the invention] The present invention relates to a structure for attaching an outlet grille.

The conventional Suita grill installation has a structure as shown in Figure 1 for example.
There is something like the one used in the dual-purpose air conditioner shown in Figure 15. 1 in the figure is the defroster duct, and the ventilator
Taduct 2. It is connected to the heater unit 4 as a ventilation duct of the air conditioner together with the heater rear duct 3, etc.
The blowout opening 5 of the defroster duct 1 and the instrument panel 6 are installed by fixing the Suita grill 1 through the opening 6&t.

The Suita grill 7 is a grill portion 9 that directs air blown from the defroster duct 1 toward the front windshield 8.
and a fitting part 10 in the shape of seven parallel flange integrally formed on the lower surface of the grill part 9. And a blowout grill.

The grill part 9 is inserted into the Suita opening [5] and fixed in the fitting part 10 until it comes into contact with the instrument panel 6.

In the figure, reference numeral 11 denotes a sealing member 9 made of an elastic synthetic resin material such as urethane, which is attached to the cover 8 to the rising edge 5a of the Suita opening 5, and then left. That is, this 7-hole member 11 prevents air from leaking from the defroster duct 1 by filling the gap 12 between the fitting part 10 of the blow-off grille 1 and the blow-off opening 5.

In the figure, 13 is the dash end panel, to which the defroster duct 1 is secured with screws, 14 is the dash lower panel, and 15 is the cooler unit.

16 is an intake box.

However, in terms of the structure of such conventional outlet grill installation, the installation of the instrument panel 6 to the outlet opening SS of the ventilation duct such as the defroster duct 1 is difficult.
In order to insert and fix the fitting part 10 of the outlet grille 7 through the ventilation duct and the instrument panel 6t, if the relative position between the outlet opening 5 and the mounting opening 6a is shifted, the outlet grille 7 will be The fitting part 10 is a sealing material 1
This prevents air from coming into contact with the instrument panel 6 from the gap 12 (as shown by the arrow in Figure 5).
If the air leaks into the interior (arrows in Figure 5), it may cause a decrease in ventilation efficiency or abnormal noises due to the air being blown out.

This invention focuses on these conventional problems and has been developed to improve the Suita opening of nine ventilation ducts.

By providing an elastic sealing member with a lip portion that closes the connection between the outlet opening and the fitting portion of the Suita grill,
The purpose is to solve the above problems.

The present invention will be explained below based on the drawings.

Similarly, in the following description, common reference numerals are given to parts that are common to the conventional one, and duplicate descriptions will be omitted.

FIGS. 4 to 6 are diagrams showing an embodiment of the present invention.

First, to explain the structure, reference numeral 20 in Figure 9 is a sealing member, which is fitted over the rising edge 5a of the air outlet 11 of the defroster duct 1, and whose side edges 21 and 22 are affixed to the upper surface of the defroster duct 1. be. This sealing member 20 is made of an elastic plate material such as a synthetic resin material, and has a slit 23 along the longitudinal direction of the rising edge 5a of the blowout opening 5 approximately in the center of the entire portion of the blowout opening 5. Two opposing lip portions 24 and 24t are formed.

Next, the state in which the fitting portion 1ot of the Suita nozzle 7 is inserted and fixed into the Suita opening 5 as described above will be described. When inserting and fixing, first the fitting part 10 of the blowing nozzle I
To install the instrument panel 6, insert it through the opening 6a. Then, the fitting part 10 is attached to the lip part 2 of the 7-ru member 20.
4, so insert it into the blow-off opening 1gS until the grill part 9 comes into contact with the instrument panel 6. At this time, the lip part 24 is bent downward in the figure by the fitting part 10, and even if the insertion position of the fitting part 10 is shifted, its elasticity always makes it contact with the fitting part 10, and the connection between the fitting part 10 and the blow-out opening s5 is This will close the gap 121r.

FIG. 7 shows another embodiment.

In this embodiment, a flange portion 30 for pressurizing each seal member 20 is integrally formed into the fitting portion 10 of the blow-off nozzle 7. This flange portion 30 is inserted and fixed into the fitting portion 10f: the blow-out opening portion 5, and is placed in a diagonally downward direction at a midway position of the fitting portion 10 so as to press the sealing member 20 downward in the figure at the time of closing. It is integrally protruded towards. That is, the knoll member 2
01-Press it downward in the figure and bring it into close contact with this.

In addition to the contact between the lip portion 24 and the fitting portion 10.

Air leakage is also prevented in this part. The other configurations and functions are the same as those in the previous embodiment, so redundant explanations will be omitted.

As explained above, according to the present invention.

Its structure is such that it bends and abuts on the fitting part of the blow-off grille which is inserted and fixed into the blow-off opening of the ventilation duct, and the lip part that connects between the fitting part and the blow-off opening is connected to the blow-off opening. Since a sealing member is provided, even if the insertion/fixation position of the fitting part of the Suita grill is shifted, the lip part will always come into contact with the fitting part to prevent air leakage from the ventilation duct. Therefore, many effects can be obtained, such as improving ventilation efficiency and easily preventing abnormal noises caused by leaked air.

Further, by providing a flange portion for the seal member at the fitting portion of the Suita grill, the sound effects can be made more reliable than many of the above-mentioned sound effects.
