Description

Description: TECHNICAL FIELD The present invention relates to a front grill mounting device for an indoor unit that constitutes a separate type air conditioner.

2. Description of the Related Art A conventional front grill mounting device has a structure in which a front grill upper claw is engaged with a hook portion of an underframe body, and a lower portion of the front grill is fixed to a screw boss portion of the underframe body with a screw.

An example of the above-mentioned conventional front grill mounting device will be described below with reference to the drawings.

FIG. 5 is a sectional view of a conventional front grill mounting device.

In FIG. 5, 1 is an underframe main body, 9 is a hook portion, and 10
Is a screw boss. These are integrally molded of synthetic resin. Reference numeral 3 denotes a front grill body, and 8 denotes a claw portion formed on an upper portion of the front grill, which engages with the hook portion. Reference numeral 11 denotes a screw fixing portion formed on the lower portion of the front grill for fixing to the screw boss.

Regarding the front grill mounting device configured as described above,
The fixing method will be described below.

When fixing the front grill 3 to the underframe main body 1, first, the hooking claw portion 8 on the upper part of the front grille 3 is fitted into the hooking portion 9 on the upper part of the underframe main body 1 to determine the position. Then, the front grill 3 is fitted to the underframe main body 1, the screw fixing portion 11 under the front grill 3 is fitted to the screw boss portion 10 under the underframe main body 1, and is fixed to the underframe main body 1 with the screw 12.

SUMMARY OF THE INVENTION However, in the above-mentioned configuration, since the outlet upper part 6 at the center of the front grill 3 is not fixed, the center of the front grill 3 may float due to variations in the warp of the front grill 3 itself,
It will sink, and it will be difficult to attach and detach the air filter 13, and if you pull the air filter 13 toward you,
The force may cause the center of the front grill 3 to bend toward the front, causing damage to the center of the front grill or generating chattering noise due to vibration during driving. Further, there is a problem that the front grill 3 is warped by the heat during the heating operation, and the central portion floats up toward you.

The present invention solves the above-mentioned problems and provides a front grill mounting device capable of reliably fixing the front grill.

Means for Solving the Problems In order to solve the above problems, a front grill mounting device of the present invention is provided with a hook portion on an upper portion of an underframe main body, and further, on the front grill upper portion made of a synthetic resin, the hook portion is engaged with the hook portion. A blow-out grill having a fitting claw portion, a fixing portion fixed to the lower portion of the underframe main body by an appropriate means at the lower portion of the front grill, and further having a water tray of a heat exchanger incorporated in the air conditioner. A protrusion is provided on the upper portion of the central fulcrum for the upper and lower blades attached to the front grill, and a claw that engages with the protrusion is provided at the center of the front grill.

With the above-described structure, the present invention hooks the claw portion of the central portion of the front grill with the projection on the upper portion of the central fulcrum for the upper and lower blades attached to the blowing grill, and at the same time, the claw portion serves as the blowing grill on the upper portion of the outlet. By applying it, it is possible to prevent the central portion of the front grille from bending and to improve the strength, and the front grille is securely fixed. In addition, the central fulcrum for the upper and lower blades attached to the outlet grill and the protrusions provided on the upper part of the central fulcrum have some bending in the vertical direction, so that the central portion of the front grill can be fixed smoothly and more securely. .

Embodiment Hereinafter, a front grill mounting device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1, FIG. 2, FIG. 3, and FIG. 4 are a front perspective view, a side view of a central fulcrum, a sectional view, and an enlarged view of a central fixing portion in an embodiment of the present invention.

In the figure, 1 is an underframe main body, 9 is a hook portion, and 10 is a screw boss portion. These are integrally molded of synthetic resin. Reference numeral 3 is a front grill body made of synthetic resin, and 8 is a hooking portion that engages with the hooking portion 9 integrally formed on the front grille. Reference numeral 11 denotes a screw fixing portion integrally formed on the lower portion of the front grill, which is fixed to the screw boss. 2 is a blow-out grill which also serves as a water tray of the heat exchanger 14, 5 is an upper protrusion of a central fulcrum 16 for the upper and lower blades 15 attached to the blow-out grill, and 7 is a claw provided on the upper surface 4 of the outlet of the front grill 3. The part engages with the protrusion 5.

Regarding the front grill mounting device configured as described above,
The fixing procedure will be described below.

When the front grill 3 is fixed to the underframe main body 1, first, the hooking claw portion 8 above the front grille 3 is fitted into the hooking portion 9 above the underframe main body 1 to determine the position. Then, the front grill 3 is fitted to the underframe main body 1, the screw fixing portion 11 under the front grill 3 is fitted to the screw boss portion 10 under the underframe main body 1, and is fixed to the underframe main body 1 with the screw 12. At this time, due to the bending of the upper protrusion 5 of the central fulcrum 16 of the upper and lower blades 15 attached to the blowout grill 2, the claw portion 7 at the central portion of the front grill 3 is automatically engaged. At this time, the claw 7 in the center of the front grill
Is located in front of the outlet upper part 6 of the outlet grill 2, the fitting is more reliable, the gap between the front grill 3 and the outlet grill 2 is made uniform, and the inlet / outlet space for the air filter 13 is secured.

As described above, according to the present embodiment, by fixing the central portion of the front grille 3 by the engagement of the claw portion 7 and the protrusion portion 5, the warp of the front grille 3 itself is corrected and the expansion due to the influence of heat is expanded. With the air filter 13
Desorption becomes smooth. Further, when the air filter 13 is taken out, the center does not bend toward the front, and if the center grille of the front grill 3 is damaged or chatters, a claw at the center of the front grille 3 can prevent it.

Effects of the Invention As described above, in the front grill mounting device for an air conditioner of the present invention, the claw portion at the central portion of the front grill is engaged with the projection at the upper portion of the central fulcrum as compared with the conventional configuration, so that the front grill is The front part of the grill can be securely fixed without the center part bending forward and floating. As a result, various effects can be achieved such that the front grille is not damaged, vibrations during operation do not resonate, and chatter noise is not generated, and the air filter can be smoothly taken in and out.
