Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an air conditioner.

Conventional technology Conventionally, floor-standing, high-capacity air conditioners were
The structure was as shown in FIGS. That is, the main body 1 includes a back plate 2, a front plate 3, a side plate 4,
5, and the inside thereof is equipped with a blower 6 and a heat exchanger 7 which is inclined upwardly.
Also, inside the main body 1, the motor mounting plate 8 of the blower 6 and the receiving plate 12 of the heat exchanger 7 are installed, and the frame side plates 9,
It is fixed to both ends of 10 with screws 11 and 13. An air filter 14 divided into left and right halves is held at the suction port 15 of the main body 1 by an air filter holder 16. This air filter holder 16 is L-shaped and includes a fixing piece 16a and a holding piece 1.
6b and a guide piece 16c, and the two air filter holders 16 are joined together. 17 in the figure is a fixing hole.

Conventionally, when the main body 1 of the air conditioner is configured to be long laterally, the air filter 14 is divided into two parts as described above.
To hold the air filter holder 16 in the center part, fix the air filter holder 16 to the rear plate 2 using the hole 17 with the screw 18, insert the air filter 14 from the front, and attach the holding piece 16b and the rail part 1 of the frame side plate 9.
The configuration was such that it was held by 9.

Problems to be Solved by the Invention In such a conventional configuration, since the main body 1 is long in the lateral direction, the overall structure is such that the grill rail 20 is deflected at the central portion indicated by the arrow A when only a slight force is applied thereto. This not only weakens the frame structure but also reduces the product value.

This invention solves these problems,
The purpose is to strengthen the central part of the main body and increase the product value.

Means for solving the problem In order to solve this problem, the present invention has the main body:
Each horizontally long grill rail and a receiving plate for the heat exchanger,
A motor mounting plate is provided, the fixing piece of the air filter holder is arranged and fixed at right angles to the center of the grill rail, the receiving plate and the motor mounting plate, and the air filter holder is integral with the fixing piece, and It has a holding piece for the air filter bent on the back side, a first guide plate for guiding the air filter is provided below the fixed piece, and a second guide plate for guiding the air filter in front of the holding piece.
This is an air conditioner with a guide plate.

Function With this configuration, the back plate and the stopper of the air filter holder are fixed in the center of the main body, and each horizontally long grill rail and
Since the fixing piece of the air filter holder is fixed orthogonally to the heat exchanger receiving plate and the motor mounting plate, the grille applies pressure from above in the center of the main body in each of the horizontal directions. It is distributed among the rail, receiving plate, and motor mounting plate to prevent deflection.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, reference numeral 23 denotes the main body of the air conditioner, and the exterior is composed of a back plate 24, a front plate 25, a top plate 26, and a grill rail 27. A heat exchanger 28 is provided in the upper part of the main body 23 so as to be inclined forward, and the lowermost end of the heat exchanger 28 is provided with frame side plates 30 and 31 on both sides and screws 3.
A receiving plate 29 is fixed to 2. Further, a motor mounting plate 34 to which a blower 33 is fixed is arranged at the lower part of the main body 23, and this motor mounting plate 34 is attached to the frame side plates 30, 31 with screws 35.
is fixed to. Suction port 3 is provided on the bottom surface of the main body 23.
8, and an air filter 36 divided into left and right parts with an air filter holder 37 in the center is provided so as to face the suction port 38. 39 in the figure is a base at the bottom of the main body 23.

As shown in FIG. 3, the air filter holder 37 consists of a fixing piece 40 that stands up vertically, and a holding piece 41 that is bent in the depth direction and holds the air filter 36 at the center. is bent upward and screws 42 are attached to the back plate 24.
A stopper piece 43 is provided which is fixed by a screw. Further, below the fixed piece 40 is a first guide plate 44 for guiding when inserting the air filter 36.
(provided on both sides), and holes 45 for fixing to the grill rail 27, the receiving plate 29, and the motor mounting plate 34. A second guide plate 46 is provided on the front side of the holding piece 41 for guiding the air filter 36 when it is inserted. 47 in the figure is a hole for fixing to the back plate 24.

Next, to explain the assembly, the grill rail 2 is placed above the frame side plates 30, 31 provided on both sides.
7, and further, both ends of the receiving plate 29 are fixed to the frame side plates 30 and 31 with screws 32. Next, attach both ends of the motor mounting plate 34 to the frame side plate 3.
0,31 with screws 35. Then, the air filter holder 37 is placed in the center. First, the stopper piece 43 of the air filter holder 37 is fixed to the back plate 24 with the screw 42. Next, a hole 45 provided in the fixing piece 40 of the air filter holder 37 on the front side.
It is fixed to the motor mounting plate 34 using fixing screws 48. Next, screw the receiving plate 2 with the screw 49.
9, and then sequentially to the grill rail 27 using screws 50. After the air filter holder 37 is fixed at the center so as to be perpendicular to the motor mounting plate 34, which is configured to be long in the horizontal direction, the receiving plate 29, and the grill rail 27, the air filter 36 is inserted from the front side. This insertion is facilitated by the first guide plate 44 and the second guide plate 46, and is held by the holding piece 41, and both ends are attached to the rail portions 51 provided on the base 39. It is held by twisting it.

As a result, if some force is applied to the center of the grill rail 27 from the arrow B, the force will be transmitted to the grill rail 27 and the receiver via the fixing piece 40 of the air filter holder 37. Board 2
9. They are distributed over the motor mounting plate 34, and deflection is prevented by such a reinforcing device.

Effects of the Invention As is clear from the description of the above embodiments, the present invention includes a laterally long grill rail, a receiving plate, and a motor mounting plate on the front side of the main body, and the central part The fixing pieces of the air filter are fixed perpendicularly to each other, and the reinforcement is done so that the pressing force from the center is distributed to the grill rail, receiving plate, motor mounting plate, etc., so even if the force is applied above the front panel, This has the effect of preventing bending even when the load is applied, making the overall frame structure stronger, and improving quality.
