Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to a mechanism for opening and closing a suction port provided on the front panel of an air conditioner.

[Prior Art] Fig. 4 is a vertical sectional view of the air conditioner shown in Japanese Utility Model Publication No. 58-34329. Air outlet (3)
It is covered by a front panel (4) with a (5) is an air path formed by a guide wall (6) in the harmonizer main body (1), which sequentially passes a filter (7), a heat exchanger (8), a blower (9), and a wind direction toward the downstream side. Adjustment plates (10) are provided respectively. (11) is a suction port opened in the suction grill (2).

When the blower (9) rotates in the above configuration, the indoor air around the conditioner main body (1) is sucked in through the suction port (11) of the suction grill (2), and the filter (7) and the heat exchanger (
8), passes through the blower (9), and is blown into the room again from the air outlet (3).

[Problem to be solved by the invention] Since the conventional air conditioner is configured as described above,
The suction grill has a suction port that is always open, and therefore has an unfavorable external appearance, such as the internal mechanism being directly visible through the suction port.

If the suction port is made narrower to solve this problem, the volume of the suction flow increases, leading to problems such as increased noise.

This invention was made to solve the above-mentioned problems, and its purpose is to open the suction port on the front panel when the device is in operation, but to close it when the device is stopped.

[Means for Solving the Problems] In the air conditioner according to the present invention, the suction grill in which the closing plate and the grill hole plate are formed in an arc shape with a series of widths can be rotated to the back of the suction port on the front panel. When the equipment is in operation, the above-mentioned grill hole plate is aligned with the intake port on the front panel to ensure a suction air path, but when the equipment is stopped, a blocking plate is installed on the front panel in place of the above-mentioned grill hole plate. The internal mechanism is shielded from the outside by matching the suction port of the

[Function] In the air conditioner according to the present invention, the internal mechanism is completely invisible when the device is stopped, and a suction air path with less suction flow movement is formed during operation.

[Example 1] An example of the present invention will be described below. That is, in FIGS. 1 to 3, the same or corresponding parts as those in FIG. The suction grill of the present invention has an arcuate shape having a predetermined width and is rotatably provided opposite to the back of the suction port (13) provided in the device, and the suction grill is connected to the suction port (13) when the device is stopped. a circular arc-shaped closing plate (14) of a predetermined width for closing the air intake port (14); and a circle of a predetermined width that is formed in series with this and covering the suction port (13) in place of the closing plate (14) when the device is in operation. It is composed of an arc-shaped grill hole plate (15). (12a) (12
b) is the pivot shaft of the suction grill, (16) and (17) are the mounting bosses protruding from one inner end surface of the front panel (4), and (18) is the bearing protruding from the other inner end surface. , (1
9) is a motor fixture for fixing the drive motor (20), which is attached to one support shaft (12a) of the suction grill (12).
It has a bearing hole (21) into which the drive motor (20) is fitted, and mounting bosses (22, 23) for the drive motor (20), and is attached to the mounting bosses (16, 17) with screws (24). (
25) is the mounting screw for the drive motor (20), (26)
is the crank installed on this drive motor (20).

This crank connects the drive motor (20) to the motor mount (1).
9), turn the support shaft (1) of the suction grill (12)
2a), and the rotation support shaft (12b) is supported by the bearing (18).

Figure 2 shows the state in which the air conditioner has stopped operating. In this state, the blocking plate (14) of the suction grill (12) is blocking the inlet (13) of the front panel (4), and the air conditioner is operating for the first time. The drive motor (20) is rotated by the control signal from the air conditioner controller, and the suction grill (12) is rotated by the support shaft (1).
2a) It rotates around (12b), and as shown in FIG. 3, the grill hole plate (15) is positioned in place of the suction port (13) on the front panel, and in this state, the suction air path is secured.

When the air conditioner is stopped, the suction grill (12) returns to its initial state.

[Effects of the Invention] The air conditioner of the present invention is constructed as described above, and when the device is stopped, the suction port on the front panel is blocked by the closing plate of the suction grill, so the internal mechanism is not visible and the appearance is improved. No problems occur, and since the suction port is fully open when the device is in operation, the suction flow is small and low noise can be maintained.
Another effect is that dust is prevented from entering the air conditioner when it is not in operation.

[Brief explanation of drawings]

Fig. 1 is an exploded perspective view showing an embodiment of the air conditioner of the present invention, Figs. 2 and 3 are vertical cross-sectional views in an assembled state, Fig. 2 shows the device in a stopped state, and Fig. 3 shows an air conditioner in a stopped state. indicates the operating status. FIG. 4 is a vertical sectional view of a conventional air conditioner. In the figure, (1) is the harmonizer main body, (4) is the front panel, (
12) is a suction grill, (13) is a suction port, (14) is a closing plate, and (15) is a grill hole plate. In other figures, the same reference numerals indicate the same or corresponding parts.

Claims (1)

[Claims] A suction grill in which a closing plate and a grill hole plate are formed into an arc shape with a series of widths is rotatably installed opposite to the back of the suction port provided on the front panel of the harmonizer body, and when the device is stopped, the closing plate is closed. The air conditioner is characterized in that the suction port is closed off and the grill hole plate is rotated to the suction port during operation of the device to ensure a suction air path.
