Abstract

PROBLEM TO BE SOLVED: To easily attach/detach an air filter, to improve convenience in cleaning the air filter, and to control deterioration in the performance of an air conditioner by opening an air inlet panel and a shielding plate of an air inlet of an air conditioner. SOLUTION: A box body comprises a cabinet 1, a decorative frame 2 and an air inlet panel 3. An air outlet 2a and an air inlet 3a are formed in the decorative frame 2 and the air inlet panel 3 respectively. A shielding plate 5 to open/shield the air inlet supported by guide rails 4 on right and left ends is provided rearward of the air inlet 3a. The shielding plate 5 is operated in the vertical direction along the guide rails 4, and shields the air inlet 3a when the shielding plate is moved to the lower end, and opens the air inlet when it is moved to the upper end. A heat exchanger 6 and a crossflow fan 7 are stored in the box body, an air filter 8 is arranged forward of the heat exchanger 6, and an air filter can be easily attached/detached by moving the shielding plate 5.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air conditioner,
In particular, the present invention relates to a structure in which a mechanism for opening or blocking an air suction port and a panel having an air suction port can be opened independently or simultaneously in a direction to facilitate attachment and detachment of an air filter.

[0002]

2. Description of the Related Art A conventional air conditioner is disclosed in Japanese Patent Laid-Open No. 4-145.
And Japanese Patent Application Laid-Open No. Hei 5-187706, a mechanism for opening or blocking the air inlet is provided.

[0003]

In the above-mentioned prior art, there is a problem that the operation of the mechanism for opening or closing the air suction port is not considered for facilitating attachment and detachment of the air filter.

An object of the present invention is to make the opening / closing or shielding mechanism operable to increase the space for inserting and discharging the air filter, and to make it easier to attach and detach.

[0005]

In order to achieve the above-mentioned object, among the components constituting a mechanism for opening or closing the air suction port, a guide rail of a shielding plate for opening or closing the air suction port is provided. A mechanism is provided that moves in a direction other than the opening or blocking operation to increase the space for inserting and discharging the air filter.

Further, the above-described series of operations is a mechanism that operates following the operation when the air suction panel is opened.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional view of an air conditioner according to an embodiment of the present invention. The housing includes a cabinet 1, a decorative frame 2, and a suction panel 3. An air outlet 2a is formed in the decorative frame 2, and an air inlet 3a is formed in the suction panel. A shield plate is provided at the rear of the air inlet to open or shield the inlet supported by the guide rails 4 at both left and right ends. 5 are provided. In the figure, the state fixed to the upper end is shown, but the shielding plate 5 moves in the vertical direction in the figure along the guide rail 4, and when moving to the lower end, shields the air suction port 3a. It is designed to open when you move. The guide rail 4 has a rotation fulcrum 4 a and is connected to the decorative frame 2. Heat exchanger 6 inside the housing
And a once-through fan 7. An air filter 8 is disposed in front of the heat exchanger 6. Although the fan motor and the electric components are not shown, they are provided as is well known.

FIG. 2 shows a state when the air filter is attached and detached. The suction panel 3 is opened by rotating the lower part, and can be removed by further increasing the opening degree. Following the operation of opening the suction panel 3, the guide rail 4 and the shielding plate 5 rotate around the rotation fulcrum 4a, stop after rotating by a certain angle. At this time, a space is formed between the shielding plate 5 and the filter guide 9. This space is large enough to allow a hand to be inserted when the air filter 8 is attached and detached, and the air filter 8 can be easily attached and detached.

When the suction panel 3 is removed, the guide rail 4 and the shielding plate 5 similarly rotate about the rotation fulcrum 4a, rotate at a certain angle, and then stop. In this case, a wider space can be formed. In the figure, shielding plate 5
Is stopped at a position where the air suction port 3a is shielded, but can be rotated even at an open position as shown by a two-dot chain line.

As described above, by a series of operations, the space for mounting and dismounting the air filter 8 is widened to reduce the burden of air filter operation which is often performed at relatively high places, and to facilitate the cleaning so that the air can be easily cleaned. A decrease in the basic performance of the harmonic device can be suppressed.

[0011]

According to the present invention, the air filter can be easily attached and detached by opening the air inlet panel of the air conditioner and the shield plate of the air inlet to the front. As a result, the usability associated with the cleaning of the air filter is improved, and further, there is an effect of suppressing a decrease in the basic performance of the air conditioner.
