[Prior art]

 FIG. 4 shows a wall-mounted air conditioner. In the figure, reference numeral 1 is a wall-mounted air conditioner main body, and an air suction port and an air suction port are provided on the front surface of the air conditioner body 1. An air outlet is formed below. At the air suction port, a suction grill 3 having a suction port formed by a plurality of lateral ribs 2 arranged at intervals in the vertical direction is arranged. There are three suction grilles 3 arranged at the air suction port, as shown in FIG. 7, but the number thereof is variable according to the width of the air suction port. The suction grille 3 has its upper end locked to the air conditioner body 1 and, as shown in FIG. 5, fixing collars 4 on both sides of the lower end of the suction grille 3 fixed to the air conditioner body 1 by screws. It is fixed to.

On the back side of the suction grill 3, as shown in FIG. 7, an air filter 5 that is detachable from the lower end of the suction grill 3 by being moved up and down is arranged. As shown in FIG. 6, this air filter 5 is pressed from the back side to the suction grill 3 side by a cushion material 6 such as foamed rubber forming the air conditioner body 1 side, and is provided at both lower ends. The claw 7 is locked to the mounting position by locking the lower surface rib 8 of the suction grille 3. Further, the cover pieces 3a are mounted so as to bridge the adjacent suction grilles 3. The cover piece 3a covers a gap formed between the adjacent suction grilles 3 and efficiently guides the heat-exchanged air to the suction grilles 3.

On the other hand, at the air outlet provided at the lower end of the air conditioner body 1, as shown in FIG. 4, an outlet grill 9 having a mechanism capable of changing the direction of the outlet air is provided. This air conditioner main body 1 can be operated by operating the operation switch 10 to switch between air blowing, cooling, and heating operations and stop operation.

[0005]

[Problems to be solved by the device]

 In the conventional wall-mounted air conditioner, the lower surface ribs 8 on which the claws 7 of the air filter 5 are locked are located at the lower end portions on both side ends of the suction grill 3, and this portion is sucked through the fixing collar 4. Since the position where the grill 3 is fixed to the air conditioner main body 1 is approached, almost no bending of the suction grill 3 can be expected, and therefore a large force is required when locking and unlocking the air filter 5. However, there is a problem that the operability when attaching and detaching is poor. Further, since the locking means is only the claw 7, if the mounting is incomplete, the claw 7 will come off the lower rib 8 and the air filter 5 will fall off from a predetermined position on the back side of the suction grill. is there.

The present invention has been made in view of the current situation, and an object thereof is to provide a wall-mounted air conditioner that has good operability when attaching and detaching an air filter and that does not cause the air filter to fall off.

[0007]

[Means for Solving the Problems]

 As a means for achieving the above object, the present invention arranges a suction grille on the front surface of an air conditioner main body, and vertically moves between the air conditioner main body and the suction grille to attach and detach from the lower end of the suction grille. In a wall-mounted air conditioner in which a possible air filter is arranged, a first claw that engages with a lower rib of a suction grill is provided at a widthwise central lower end of the air filter, and a widthwise end portion of the air filter is provided. A second pawl that engages with a plurality of horizontal ribs provided in the vertical direction of the suction grille is provided at a position closer to the upper side from the lower end in the vicinity, and the second pawl is attached from below when the air filter is mounted. The feature is that it is locked to the lateral rib above the second.

[0008]

[Action]

 In the wall-mounted air conditioner according to the present invention, the first claw is provided at the central portion in the width direction of the air filter, and in this portion, the bending of both the suction grill and the air filter can be expected sufficiently. The second pawl is provided near the widthwise end of the air filter, but at a position closer to the upper side from the lower end, and since this part is also separated from the fixed position of the lower end on both ends of the suction grille, Sufficient bending of the air filter can be expected. Therefore, the air filter can be attached and detached with a small force, and improvement in operability can be expected.

The second claw is engaged with the inner end of the horizontal rib that is the second from the bottom or above the horizontal rib of the plurality of horizontal ribs of the suction grille provided in the vertical direction when the air filter is mounted. Even if each claw comes off from the bottom rib or the inner edge of the upper horizontal rib, the second filter will fall slightly inside the horizontal rib at the lower end even if the claws are not attached to the bottom rib or the inner edge of the upper horizontal rib. Locked at the end to prevent further fall of the air filter. Therefore, it is possible to prevent the air filter from falling off.

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a main part of a wall-mounted air conditioner according to the present invention. In the figure, reference numeral 3 is a suction grill, and a front surface of the suction grill 3 is arranged at intervals in the vertical direction. A suction port is formed by the plurality of horizontal ribs 2, and fixing flanges 4 for screwing the suction grill 3 to an air conditioner body (not shown) are provided at lower end portions on both sides of the suction grill 3. There is. On the back side of the suction grill 3, as shown in FIGS. 1 to 3, there is arranged an air filter 15 which is removable from the lower end of the suction grill 3 by being moved up and down. The air filter 15 is pressed from the back side to the suction grill 3 side with a cushion material 6 such as foam rubber. As shown in FIGS. 1 to 3, a first claw 17a is provided at the lower center of the air filter 15 in the widthwise direction, and the first claw 17a is attached to the lower surface rib 8 of the suction grill 3. It is designed to be snap-locked.

Further, as shown in FIGS. 1 to 3, at both ends of the air filter 15 in the widthwise direction, second claws 17b are provided at positions which are located above the lower end by a predetermined dimension. Each of these second claws 17b is adapted to be snap-fitted to the horizontal rib 2 and, when the air filter 15 is attached, as shown in FIG. It is designed to be locked at the inner end. As a result, even if the air filter 15 is lowered due to insufficient mounting, as shown in FIG. 3, when the second pawl 17b is locked by the lateral rib 2 at the lower end, the air filter 15 is not lowered any further. The air filter 15 is prevented from falling off.

Next, the operation of this embodiment will be described. When the air filter 15 is attached to the back side of the suction grill 3, as shown in FIG. 2, the first claw 17a is snapped to the lower surface rib 8 and the second claw 17b is the second from the bottom. The lateral rib 2 is snap-locked to the inner end of the lateral rib 2, whereby the air filter 15 is locked in the mounted state. By the way, a portion of the lower surface rib 8 where the first claw 17a is locked is a central portion in the lateral width direction of the suction grill 3, and this portion is easily bent even by a small force as shown by reference numeral 11 in FIG. In addition, it is the portion with the largest amount of bending. Therefore, when the first claw 17a is locked to or unlocked from the lower surface rib 8, a small force is required and the operability can be improved.

Further, the lateral rib 2 to which the second pawl 17b is locked is separated from the fixing collar 4, and the lateral rib 2 itself has a structure that is easily bent, so that the lateral rib of the second pawl 17b is formed. A small force is required to lock and unlock the 2 inner end. Therefore, operability can be improved.

When the air filter 15 is attached, the second claw 17b is engaged with the inner end of the second horizontal rib 2 from the bottom as shown in FIG. Even if the condition is insufficient and the air filter 15 starts to descend, if the second claw 17b is locked to the inner end of the lateral rib 2 at the lower end as shown in FIG. The air filter 15 can be prevented from dropping further, and the air filter 15 can be prevented from falling off. Further, in this state, the user can easily visually check that the air filter 15 is not properly mounted, so that the air filter 15 can be easily remounted and the safety can be improved.

In the above embodiment, the case where the second claws 17b are provided on both sides of the air filter 15 has been described, but if the second claws 17b are provided on one of the two sides, the desired result is obtained. The effect can be expected. The second pawl 17b does not necessarily have to be locked to the lateral rib 2, but may be locked to another locking portion provided on the inner surface of the suction grill 3.

[0016]

[Effect of device]

 As described above, according to the present invention, the first claw that engages with the lower surface rib of the suction grille is provided at the lower center of the air filter in the width direction, and the first filter is provided upward from the lower end near the width direction end of the air filter. Since the second claw that engages with the inner ends of the plurality of horizontal ribs provided in the vertical direction of the suction grille is provided at the above position, the air filter can be attached and detached with a small force, and the operability is improved. Can be improved.

Further, since the second claw is adapted to be locked by the lateral rib above the second from the bottom when the air filter is attached, the attachment state is not sufficient and the air filter is lowered. Even if the air filter is lowered, the air filter is prevented from falling after the second pawl is engaged with the lateral rib at the lower end, which prevents the air filter from falling off and improves safety.
