Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mechanism for attaching and detaching a filter placed at an indoor air intake port of a wall-mounted air conditioner.

(Prior art) An example of a conventional mechanism of this kind is shown in FIGS. 5 to 10.
As shown in the figure. In FIGS. 5 to 10, 1 is an air conditioner, and 2 is a filter made of synthetic resin or the like. The filter 2 has a rectangular thin plate shape as a whole, and has a flange 2a protruding forward at its lower end, which serves both to maintain its rigidity and to hold a finger during attachment and detachment, and a flat plate portion 2b at the top of the flange 2a.
However, a plurality of vertical bars 2c and a plurality of horizontal bars 2d orthogonal thereto are further formed on the top thereof. There is a net 2 between the vertical bar 2c and the horizontal bar 2d.
e is stretched.

To install the filter 2, insert the filter 2 into the air conditioner 1 through the filter attachment/detachment hole 1a provided at the front of the lower surface of the air conditioner 1, and then insert the filter 2 into the air conditioner 1.
e is raised so that it is located behind the indoor air suction port 1c provided on the front panel 1b of the air conditioner 1. Then, the flat plate portion 2b of the filter 2
Two protrusions 2f protruding from the front surface of the front panel 1b engage with a protrusion 1d protruding rearward from the lower end of the front panel 1b, and the support spring 3 supported by the air conditioner 1 The filter 2 is pressed forward by contacting the center part, and the center part of the push-down spring 4 whose both ends are fixed to the air conditioner 1 engages with a claw 2g protruding from the center of the front surface of the flat plate part 2b. The filter 2 is pressed downward.

When taking out the filter 2, as shown in FIG. 5, when the flange 2a of the filter 2 is pushed backward with a finger, the lower end of the filter 2 moves backward against the support spring 3, and the protrusion 2f separates from the protrusion 1d. Then, the filter 2 is pushed down by the push-down spring 4, and the vertical bar 2c
The protrusion 2h protruding from the front surface of the filter is lowered to a position where it engages with the protrusion 1d, that is, a removal position, and its lower end advances from the filter attachment/detachment hole 1a, as shown in FIG. Therefore, the filter 2 is grasped by the flange 2a of the filter 2, and the filter 2 is once pushed backward to cause the protrusion 2h to ride over the protrusion 1d, and then pulled downward to be pulled out from the inside of the air conditioner 1.

(Problems to be Solved by the Invention) In the conventional mechanism described above, when the filter 2 is pushed down by the push-down spring 4 when the filter 2 is taken out, as shown in FIG. 3 comes off from the flat plate part 2b and the net 2
Since the net 2e is bent in contact with the net 2e, the filter 2 cannot be held by the pressing force of the support spring 3, and the filter 2 falls off. Therefore, the filter 2 is locked at a predetermined take-out position by providing a protrusion 2h and locking the protrusion 1d with the protrusion 1d. Therefore, in order to pull out the filter 2 from the take-out position, grasp the flange 2a and press the protrusion 1d. Since the filter 2 has to be pushed in so that the filter 2h goes over the protrusion 1d and then pulled down, there is a problem in that the ease of removing the filter 2 is significantly impaired.

(Means for Solving the Problems) The present invention was proposed to solve the above problems, and its gist is to provide a filter having a net stretched across a plurality of vertical bars. Insert the net into the take-out position inside the air conditioner through the attachment/detachment hole provided on the bottom of the air conditioner, and push the net further against the push-down spring from this take-out position to move the net to the set position behind the indoor air intake port. In a filter attachment/detachment mechanism for an air conditioner in which the filter is locked by locking the protrusion of the filter to the front panel in this state, the filter is pushed down from the set position by the push-down spring, and the filter is pressed down from the set position by the pressing spring. In an air conditioner, the air conditioner is provided with a support that holds the filter in the take-out position by simultaneously abutting against the back surfaces of the plurality of vertical bars and pressing them forward with a spring force when the filter is in the take-out position. It's in the filter attachment/detachment mechanism.

(Function) Since the present invention has the above configuration,
When attaching a filter, insert the filter through the attachment/detachment hole to the take-out position, then press against the push-down spring and lock the protrusion of the filter to the front panel, so that the net is positioned behind the suction port. It is locked in the set position. When removing the filter, when the filter is pushed down by the push-down spring and lowered to the take-out position, the support simultaneously contacts the back surfaces of the plurality of vertical bars of the filter and presses them forward, thereby holding the filter in the take-out position. .

(Embodiment) An embodiment of the present invention is shown in FIGS. 1 to 4. Reference numeral 10 denotes a support, and a pin 10a extending horizontally from its lower end is rotatably supported on a bearing 1e provided in the air conditioner 1, and flanges 10b abutting against the vertical beam 2c of the filter 2 are provided on both sides of the front side of the support.
is installed protrudingly. This support 10 is pressed forward by a coil spring 11 disposed behind it.

The other structures are the same as those of the conventional structure shown in FIGS. 5 to 10, except that the support spring 3 and the protrusion 2h are omitted, and corresponding members are designated by the same reference numerals. There is.

When removing the filter 2, the flange 2a of the filter 2 is pushed backward with a finger to separate the protrusion 2f from the protrusion 1d, and the filter 2 is pushed downward by a predetermined amount by the push-down spring 4. However, in this state, the flange 10b of the support 10 comes into contact with the plurality of vertical bars 2c, presses the filter 2 forward, and makes it stand still at the removal position. Thereafter, the filter 2 can be pulled out from the air conditioner 1 by grasping the flange 2a and pulling it down.

(Effects of the invention) In the present invention, when the filter is in its take-out position, the support simultaneously contacts the back surfaces of the plurality of vertical bars and presses them forward, thereby holding the filter in its take-out position. Therefore, it is no longer necessary to provide a protrusion as in the past to hold the filter in its removal position.
Further, in order to pull out the filter from its removal position, it is not necessary to push the filter once and then pull it out as in the conventional case, but it is sufficient to simply pull it out, so that the operation of attaching and detaching the filter becomes extremely easy.

In addition, since the support contacts the back surfaces of multiple vertical bars at the same time, it can apply a stable pressing force toward the front of the filter, thereby stabilizing the operation of the filter and making it possible to attach and detach it smoothly. Become.
