Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner provided with a suction grill that can be opened / closed and detached.

[0002]

2. Description of the Related Art An example of a conventional wall-mounted indoor unit of a separation type air conditioner is shown in FIG. In FIG.
Reference numeral 1 is a main body of the indoor unit, 2 is a front panel fixed to the front surface of the main body 1, 10 is a suction grill that is openably and closably attached to the front upper portion of the front panel 2, and is detachably mounted, 3 is a heat exchanger,
Reference numeral 4 denotes a cross-flow type fan disposed behind the lower portion of the heat exchanger 3, 5 denotes an air outlet provided at the lower front portion of the front panel 2, 8 denotes a drain pan disposed below the heat exchanger 3, and 9 Is an air filter disposed behind the suction grille 10, and 11 is an installation plate.

At the air outlet 5, upper and lower flaps 6a for adjusting the wind direction of the blown air to be blown up and down,
6b and a plurality of louvers 7 for adjusting the direction of the blown air to the left and right.

During operation of the air conditioner, the fan 4 rotates,
Refrigerant from an outdoor unit (not shown) circulates in the heat exchanger 3. Thus, the room air is sucked into the main body 1 through the suction grille 10 and flows through the air filter 9 to remove dust contained therein. Then, it is cooled or heated by passing through the heat exchanger 3, is energized by the fan 4, and then is blown out into the room by being guided from the outlet 5 to the upper and lower flaps 6a and 6b and the louver 7.

[0005]

In the above conventional air conditioner, the shaft 12 which is disposed above the suction grill 10 and extends horizontally is fitted in the arc-shaped groove formed in the front panel 2. Therefore, when opening and closing the suction grill 10, the suction grill 10 may come off from the front panel 2.

[0006]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above-mentioned problems, and its gist is to open and close a suction grill at an upper portion thereof about an axis extending horizontally. In an air conditioner that is capable of being detachably attached to the front panel, a plurality of support legs are provided at an upper portion of the suction grill at intervals along the horizontal direction, and the tip ends of the plurality of support legs are provided. The front panel is provided with a plurality of bearings having horizontally extending shafts for insertion into the drilled holes, and at least one of the plurality of bearings has a shaft capable of moving in the horizontal direction. An air conditioner is provided, which is provided with a spring which supports the panel and biases the shaft so as to be inserted into the hole of the supporting leg from a direction opposite to that of the shaft of the other supporting portion.

[0007]

In the present invention, since the above-described structure is provided, the suction grill can be opened and closed by rotating around the horizontally extending axes of the plurality of support portions. Then, the shaft of one bearing is pulled out of the hole of the supporting leg by moving it horizontally against the spring, and then the suction grill is moved in the opposite direction to move the shaft of the other bearing to the hole of the supporting leg. Remove the suction grill from the front grill by pulling it in the opposite direction from.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. A plurality of suction grills 10 are provided at the top of the suction grill 10 at intervals along the horizontal direction.
Support legs 13A, 13B and 13C (three in the figure) are projected,
Holes 14A, 14B, and 14C extending horizontally are formed at the tips of these support legs so as to penetrate therethrough.

On the other hand, the front panel 2 has the holes 14A and 14B.
, 14C, there are provided a plurality of (three in the figure) bearings 16A, 16B, 16C with shafts 15A, 15B, 15C for insertion into them.

The support portions 16A, 16B are composed of arms 17A, 17B projectingly provided on the front panel 2 and shafts 15A, 15B projecting leftward at the tips thereof and extending horizontally.

The support portion 16C includes a bracket 17 fixed to the front panel 2 and a support plate 18 to which the base end of the shaft 15C is fixed.
The rod 19 fixed to the back surface of the support plate 18 and the rod 19
The coil spring (20) is wound around and the knob (21) fixed to the back surface of the support plate (18).

The shaft 15C and the rod 19 slidably pass through both side walls of the bracket 17. The left end of the coil spring 20 is in contact with the inner surface of the bracket 17, and the right end is in contact with the back surface of the support plate 18. Then, the knob portion 21 penetrates an opening 22 provided at the bottom of the bracket 17 and projects to the outside.

Therefore, the shaft 15C is supported by the bracket 17 so as to be movable in the horizontal direction, and is pushed toward the right by the coil spring 20 so that the hole 14C of the support leg 13 is provided.
Is inserted from the left side. The shaft 15C can be pulled out from the hole 14C by holding the knob 21 and moving it to the left against the elastic force of the coil spring 20.

When the suction grill 10 is mounted, the state shown in the figure is occupied, and the suction grill 10 is opened and closed by rotating around the shafts 15A, 15B, 15C. At this time, shaft 15
A and 15B are inserted into holes 14A and 14B from the right side, and
Since the 15C is inserted into the hole 14C from the left side, there is no risk that the suction grill 10 will come off from the front panel 2.

When the suction grill 10 is to be removed from the front panel 2 for cleaning or the like, when the grip portion 21 is held and moved to the left, the shaft 15C comes out of the hole 14C. Therefore, when the front end of the support leg 13C goes over the bracket 17 by pulling the right end portion of the suction grill 10 forward and bending it, the entire suction grill 10 is pulled horizontally toward the left. Then, the shafts 15A and 15B come out of the holes 14A and 14B, so that the suction grill 10 can be removed from the front panel 2.

[0016]

According to the present invention, the shafts of a plurality of bearings are inserted into the holes formed at the tips of the plurality of support legs, and at least one shaft is arranged in the direction opposite to that of the other shafts. Since it is inserted, it is possible to reliably prevent the suction grill from coming off the front panel when opening and closing the suction grill. Further, since the shaft of at least one of the plurality of bearings is supported by the front panel so as to be movable in the horizontal direction, and the spring for biasing the shaft to be inserted into the hole of the supporting leg is provided.
By moving this shaft against the spring, the suction grill can be easily and quickly removed from the front panel.
