Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The terms or words used in the present specification and utility model registration claims shall not be construed as limited to ordinary or preliminary meaning and should be construed as meaning and concept consistent with the technical specifications of the present invention.

FIG. 1 is an external view showing a configuration of an outer surface of a cover of a rotary display device for displaying a dust collector according to an embodiment of the present invention, FIG. 2 is a perspective view of a rotary display device for a dust collector status display according to an embodiment of the present invention. FIG. 3 is a plan view showing an enlarged configuration of the state display unit of FIG. 1; FIG. 1 to 3, the rotating display device for displaying the dust collector state of the present invention includes a PCB board 100 and a cover 200.

As shown in FIG. 2, the PCB board 100 includes a plurality of LEDs 112 connected to a dust collector to receive the status of the dust collector and arranged at regular intervals in a circular form to indicate the status of the received dust collector And a light emitting unit 110 constructed as described above.

1, the cover 200 includes a status indicator 210, which is composed of a plurality of translucent transmission windows 212 corresponding to the LEDs 112 and arranged in a spiral shape with respect to the center, . The cover 200 may further include an auxiliary status indicator 224 for indicating the status of the filter cleaning or the operation of the fan motor, and may also include a brief description of the status indicator, contact information of the maintenance manager, and the like. The spiral-shaped translucent transmission window 212 allows the status display unit 210 to be directional so that the operator can intuitively recognize the condition of the dust collector. Directionality is configured such that the LEDs arranged corresponding to the respective translucent transmission window 212 sequentially emit light so that the directionality appears to rotate in a direction perpendicular to the direction in which the vortex enters toward the center. In addition, the translucent transmission window 212 may be formed of various materials and structures for dispersing the light emitted from the LEDs emitted from the back surface into a spiral shape in the form of a translucent transmission window 212. For example, as shown in Fig. 3, it is also possible to consider dispersing light by a micro-film in the form of a net.

In addition, the state of the dust collector includes a normal state in which the dust collector is normally operated and an emergency state in which filter cleaning or filter replacement is required. In the present invention, the LED 112 of the light emitting unit 110 is sequentially turned on / Off state, and the color of the LED 112 are combined to display the state of the dust collector.

The rotational movement is configured to rotate the LED sequentially so that one LED or two or more LEDs can be configured to rotate in one direction, in a direction approximately perpendicular to the direction in which the vortex enters in a counterclockwise direction in the figure. As shown in FIG. 4 (a), a configuration in which one LED sequentially turns on and off is the most basic configuration. Although not shown, two or more neighboring LEDs are sequentially turned on / . If the intensity of light from one LED is low, two or more LEDs may be integrally rotated to increase the intensity of the rotating light.

Further, as shown in Fig. 4 (b) and Fig. 4 (c), two or more LEDs which are spaced at regular intervals and symmetrically with respect to the center may be seen to rotate at the same time. Such a configuration concentrates the human view so that the state of the current dust collector can be grasped more quickly.

Next, the display of the dust collector state by LED color is displayed in, for example, blue when the filter of the dust collector is in a normal state where cleaning or replacement is not required, green when the filter is required to be cleaned, Can be displayed in red. Such color conversion of the LED can be achieved by combining a multicolor LED or a plurality of LEDs with each of the translucent transmission windows. Accordingly, the state of the dust collector determined by the color of the LED is coupled with the rotational movement of the LED by the sequential ON / OFF, so that the operator can immediately check the state of the dust collector and cope with it. Especially in dusty and dark work environments.

In other words, in the steady state, the light emitting unit 110 may be configured such that one LED 112 or two or more mutually symmetrically arranged LEDs 112 sequentially repeat on / off.

Further, as shown in the drawing, if the translucent transmission window 212 is formed to have an oblique slope with respect to the radiation to the center, the rotational movement becomes more swirling so that the operator's eyes can be more concentrated.

2 and 3, the light emitting unit 110 includes a power-on display LED 114 at the center of a circularly arranged LED 112, A translucent transmission window 214 corresponding to the power-on display LED 114 may be formed. It is necessary to display the power source on the dust collector. The power indicator may be formed at the center of the light emitting portion, which is a main display window of the dust collector, rather than being formed in a separate region.

FIG. 5 is an external view showing the configuration of the outer surface of the cover of the rotary display device for displaying the dust collector according to another embodiment of the present invention, FIG. 6 is a view showing the configuration of the light blocking member according to the embodiment of FIG. 5 (A) and an exploded perspective view (b). Referring to FIGS. 5 and 6, the rotary display device of the present invention may further include a light blocking member 231, 232.

The light shielding members 231 and 232 may protrude from the back surface of the cover 200 along the rim of the translucent transmission window 212. The light shielding members 231 and 232 are formed in a C-shape including the center of the convex surface of the translucent transmission window 212, that is, the front surface 231 in the direction in which the rotational movement proceeds And further includes a bottom blocking member 238 having an LED insertion opening 234 for receiving the LED 112 so that light is emitted from all sides except for the opposite side 236, It can be configured to be blocked. With such a configuration, the rotary display device of the present invention is configured to open only to the opposite side of the direction in which the LED light trapped in the translucent transmission window 212 is moved during the rotational movement of the LEDs by the sequential on / off operation, 212 of the operator can be perceived more conspicuously in the field of view of the operator.
