Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guide structure when an air filter is attached to an air conditioning case such as an evaporator case of a vehicle air conditioning system.

[0002]

[Prior Art]

 For example, as disclosed in Japanese Utility Model Laid-Open No. 63-13320, in an evaporator case that houses an evaporator or the like that constitutes a cooling cycle of a vehicle air conditioner, an air filter is attached / detached to prevent dusting in the vicinity of a fitting port with a blower case. It is installed as possible. Such an air filter mounting operation is performed by inserting the air filter from the lower part of the instrument panel into the mounting long hole provided in the evaluation case at the foot of the passenger seat in the passenger compartment.

[0003]

[Problems to be solved by the device]

 However, the passenger's seat in the passenger compartment is generally narrow, and it is difficult to insert the air filter from the lower part of the instrument panel by visually checking the mounting slot provided in the evaporator case. The air filter could not be inserted easily, and the work of installing the air filter was difficult.

Therefore, an object of the present invention is to provide a guide structure for attaching an air filter, which facilitates the work of attaching the air filter to an air conditioning case such as an evaporator case.

[0005]

[Means for Solving the Problems]

 Therefore, the gist of the present invention is an air conditioner in which an air filter body having a filter member stretched and an air filter having a handle provided on the air filter body are attached to an air conditioning case from an attachment long hole, A guide wall is provided at one end of the attachment slot, and one or more ribs are provided on the outer surface of the air conditioning case in the longitudinal direction of the attachment slot.

[0006]

[Action]

 Therefore, the end of the air filter comes into contact with the guide wall, the tip of the air filter is pressed against the rib, and then the air filter is moved along the rib, so that the air filter is naturally guided to the mounting long hole. .

[0007]

【Example】

 An embodiment of the present invention will be described below in detail with reference to FIGS.

First, the structures of the air filter 1 and the evaporator case 8 will be described with reference to FIGS. 1 to 3.

Most of the air filter 1 is composed of a filter main body 2 on which a fine mesh-shaped filter member 5 is stretched, and its tip portion 2 a is attached to an attachment long hole 11 provided in an evaporator case 8 described below. When inserting, the mounting elongated hole 11 is rounded so as not to scratch. Further, the base portion 2b of the filter body 2 is formed so as to be gradually thicker than the tip portion 2a, and the locking portion 3 is provided on the base portion 2b.

The locking portion 3 is formed in a brim shape so as to project in a direction perpendicular to the entire circumference of the base portion 2b of the air fierter 1, has a relatively thin thickness, and one end thereof is bent to form a bent portion 3a. ing. Further, in this engaging portion 3, two notch grooves 4 and 4 are formed at appropriate positions in the longitudinal direction portion. The ribs 12 and 12 described below are inserted.

A sealing material 6 made of a soft material such as urethane is attached to the upper surface (on the filter body side) of the locking portion 3 so as to wrap around the base portion 2b of the filter body 2. Further, a rectangular parallelepiped handle 7 is provided on the lower surface of the locking portion 3.

The evaporator case 8 accommodates the evaporator 100 and the like constituting a cooling cycle of the vehicle air conditioner, and a blower fitting port 9 is formed on one side of the evaporator case 8, and a blower is provided through the blower fitting port 9. Connect to a blower case (not shown) that stores the items. This blower fitting port 9 is surrounded by fitting walls 9a and 9b on the outer periphery for fitting with a blower case, and the fitting wall 9b is formed longer than the fitting wall 9a. , One end (downward in FIG. 2) extends downward in FIG. 2 to form the guide wall 10.

In FIG. 2 of the evaporator case 8, an elongated downward surface 8a is formed, and an elongated attachment elongated hole 11 is formed in the surface 8a. The mounting elongated hole 11 is formed in a direction perpendicular to the blower fitting port 9 described above.

Further, an inclined surface 13 is formed at one end of the slender downward-facing surface 8 a between the slender surface 8 a and the guide wall 10, and in the longitudinal direction of the attachment slot 11, the evaporator case 8 is formed. Two quadrangular pyramid-shaped ribs 12, 12 are formed at appropriate distances on the standing wall surface 8b following the elongated downward surface 8a.

The ribs 12, 12 are configured such that their bottom surfaces are in contact with the surface 8a and one side surface is in contact with the standing wall surface 8b, and are fitted into the cutout grooves 4, 4 formed in the locking portion 3 of the air filter 1. In addition, when the air filter 1 is inserted, it engages with the guide and reinforces the evaporator case 8.

In FIG. 4, a locking groove 13 is formed inside the evaporator case 8 at a position facing the mounting elongated hole 11 into which the tip portion 2 a of the air filter 1 is inserted when the air filter 1 is mounted. Has been done.

In the above-described configuration, when the air filter 1 is mounted on the evaporator case 8, as shown in FIGS. 4 and 5, the tip 2a of the air filter 1 is pushed against the vertical wall surface 8b of the evaporator case 8. At the same time, the one end (short side direction) of the air filter 1 is pressed against the guide wall 10 as well. As a result, lateral positioning is performed. After the positioning, when the air filter 1 is advanced, the tip portions 2a come into contact with the ribs 12, 12, and when the ribs 12, 12 are further advanced with the ribs 12, 12 being guided, the tip portions 2a are guided to the attachment slots 11. Then, when it is advanced again, it is inserted into the mounting elongated hole 11, the tip portion 2a reaches the inside of the locking groove 13, and the mounting is completed.

At the final stage of attachment of the air filter 1 to the evaporator case 8, the ribs 12, 12 are fitted into the cutout grooves 4, 4 and when the attachment of the air filter 1 is completed, the ribs 12, 12 are most removed. Since the thick bottom portion fits into the cutout grooves 4 and 4, it is possible to strongly engage with the locking portion 3 and deform the sealing material 6 to improve the sealing.

As described above, the air filter 1 can be easily mounted by the guide wall 10 and the guides of the ribs 12 and 12 even in an invisible state.

Although the number of the ribs 12 is two, the number is not limited to this, and the number of the ribs 12 is not limited as long as the above effects can be obtained. In addition, since the present invention can be dealt with by modifying the conventional molding of the ever case 8 and the air filter 1, there is also an advantage that there is no problem of cost increase due to increase of parts and assembly man-hours. ing.

[0021]

[Effect of the device]

 According to this invention, the guide wall of the evaporator case and the ribs allow easy positioning when inserting into the mounting slot of the air filter, which facilitates insertion of the air filter into the mounting slot of the evaporator case. Since it can be done, it is possible to easily install the air filter even in an invisible state.
