Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an air conditioner, and particularly to a suction mechanism thereof.

[Prior Art] Fig. 5 and Fig. 6 are a perspective view and a sectional view of a conventional air conditioner shown in, for example, Japanese Utility Model Publication No. 58-34329. is a suction grill 2 provided opposite to the suction part A.
and a front panel 4 having an air outlet 3. Reference numeral 5 denotes an air passage formed by a guide wall 6 in the main body 1, which communicates the air outlet 3 from the suction grille 2, and sequentially connects the air outlet 3 from the suction grille 2 side to the filter 7, heat exchanger 8, blower 9, and wind direction. Adjustment plates 10 are provided respectively. 11 is an opening provided in the suction grille 2.

Next, we will explain its operation. When the blower 9 rotates, the air around the main body 1 follows the air path 5, is sucked in through the opening 11 provided in the suction grille 2, passes through the filter 7 and the heat exchanger 8, passes through the blower 9, and then exits from the outlet 3. It's blown out. As the surrounding air passes through the heat exchanger 8 in this way, heat is exchanged and the air is conditioned.

[Problems to be Solved by the Invention] Since the conventional air conditioner is configured as described above, the suction grill provided in the suction section must have an opening, and the internal mechanism can be accessed from the opening. However, if the opening is narrowed in order to improve the design, fluid loss in the suction section increases, the air volume decreases, and noise increases.

This invention was made to solve the above-mentioned problems, and its purpose is to improve the design of a suction panel.

[Means for Solving the Problems] The air conditioner according to the present invention includes a panel plate provided on the front surface of the suction portion, a first position where the panel plate closes the suction portion, and a suction portion opening. a panel board drive mechanism that moves the panel board to a second position for securing and forming a suction air path; The panel board drive mechanism is provided with a controller that controls the panel board drive mechanism to move the panel board.

[Function] In the air conditioner according to the present invention, when the power is turned off, the panel plate drive mechanism moves the panel plate to the first position to close the suction section according to the control signal from the controller, and when the power is turned on, the panel plate drive mechanism moves the panel plate to the first position according to the control signal from the controller. A control signal moves the panel plate to the second position to secure a suction opening and form a suction air path. In this way, since the suction opening is obtained by moving the panel plate, there is no need to provide an opening in the panel plate, and this can be used as a design surface.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing one embodiment of the present invention, in which 1 and 3 to 10 indicate the same or corresponding parts as the same reference numerals in FIGS. 5 and 6, 11 indicates a panel opening, and 12 13 is a panel plate provided opposite the front surface of the suction portion A in place of the conventional suction grill 2; 13 is a protrusion coupling portion having a female screw portion; 14 is a lead shaft provided on the panel plate 12; , 15 is a step motor fixed to the main body 1, 16 is a rotating shaft of the step motor 15 having a male threaded portion screwed into the female threaded portion of the protrusion coupling portion 13, and 17 is a rotating shaft of the step motor 15 and the rotating shaft 1.
6 and the protrusion coupling part 13; 18 is a bearing that fits and holds the lead shaft 14 provided on the front panel 4 so that it can slide; and the panel plate 12 is connected to the protrusion coupling part 13; Part 13
The step motor rotating shaft 16 and the bearing 18 are supported by the lead shaft 14 .

With the above configuration, when the step motor 15 rotates in one direction, the male threaded portion of the rotating shaft 16 moves in the direction in which the panel plate 12 screwed into the female threaded portion of the projection coupling portion 13 is drawn into the main body 1 side, and the opening 11 is closed. It stops at the first position where it closes. When the step motor 15 rotates in the opposite direction, the panel plate 12
and stops at a second position where a predetermined opening 11 is formed and a suction air path is formed.

FIG. 2 is an electrical control circuit diagram of the panel drive mechanism 18, in which 19 is a controller such as a microcomputer (hereinafter referred to as a microcomputer), 20 is a power-on,
an input circuit that takes in the signal from the off switch 21, 22;
2 is a central processing unit (hereinafter referred to as CPU), 23 is an output circuit, 24 is a memory, and 25 is a power transformer for the microcomputer. Note that a stepping motor 15 is connected to the output circuit 23 of the microcomputer.

Next, its operation will be explained with reference to FIG. FIG. 3 is a flowchart showing the program stored in the memory 24 of the microcomputer 19.

First, in step 26, an input from the power on/off switch 21 is received, and when the power is turned on, the step motor 15 is rotated in the forward direction in step 27. The rotation axis 1 is rotated by the forward rotation of the step motor 15.
6. The threaded portion of the protrusion coupling portion 13 is loosened, and since the panel plate 12 is prevented from rotating by the lead shaft 14, it moves in the direction of protruding from the main body 1, forming the suction opening 11 around it. The step motor is stopped at the step x0 of the step motor corresponding to the second position of the panel plate 12 where a suitable opening 11 is secured. After the suction air passage 5 with the suction opening 11 secured is formed, normal cooling (heating) operation begins in step 28. If the power switch 21 is turned off during cooling (heating) operation, this is detected in step 29, and cooling (warming) is turned off in step 30.
Terminate cell operation. After the operation is completed, the step motor 15 is reversely rotated in step 31. By the reverse rotation of the step motor 15, the threaded portion of the rotating shaft 16 and the protrusion coupling portion 13 are tightened, and the panel plate 12 is tightened.
is drawn toward the main body 1. The step motor is stopped at step x1 of the step motor, which corresponds to the first position where the panel plate is drawn toward the main body, the opening 11 around the panel plate disappears, and the panel plate closes the suction portion.

In the above embodiment, an example is shown in which the panel board 12 is moved in parallel, but as shown in FIG. It has the same effect as the example. In this case lead shaft 14 bearing 18
is not necessary, but the panel plate 12 of the protrusion joint part 13
The fixing method shall be flexible fixing.

[Effects of the Invention] As described above, according to the present invention, the panel plate is automatically moved depending on whether the power is turned on or off, the suction portion is closed when not in operation, and the suction opening is secured around the panel plate during operation. Therefore, the panel board itself does not have any openings and has a full design surface, and furthermore, it is possible to eliminate the internal devices from being exposed, which has the effect of greatly improving the design. It also has the effect of saving space when not in operation.
