Description

CLEANING DEVICE AIR-CONDITIONER IN CEILING

The present invention relates to a cleaning apparatus. More particularly, the present invention relates to a cleaning apparatus capable of cleaning a ceiling-mounted type air conditioner.

In the conventional ceiling-type air conditioner cleaning device, the nozzle rotates for cleaning. Since the vibration of the injection module or the rotation center axis of the cleaning device does not coincide with the center of the air conditioner, water or cleaning liquid which is sprayed is sprayed to an unintended position, There is a problem that it is broken. Some of the air conditioner cleaning devices attempted to solve this problem by fastening the central axis of the rotating injection module with the shaft or groove of the rotating wing of the roof air conditioner. However, additional operations are required to separate the wings for fastening with the shaft or groove of the rotary wing, and there arise problems that the wings are not joined due to the failure to correspond to various standard shafts or grooves, the shaft or groove is worn, There is a problem in that the rotating blades of the rotor are damaged.

[ The distance measurement sensor 91 and the control unit 70 increase the cleaning efficiency by matching the center of the ceiling-type air conditioner with the center of the jetting unit 10 through the distance measurement values, The center of the air conditioner and the center of the jetting portion 10 can be calibrated so that the air conditioner or the cleaning device is not damaged in shaking or motion. The control unit 70 controls the first power unit 30 so that the jet unit 10 that rotates the jet unit 10 where the distance measuring sensor 91 is located is rotated at an angle of 90 degrees, The distance measuring sensor 91 is operated to measure the distance each time the vehicle is moved at an angle of 90 degrees. That is, the distance measuring sensor 91 measures the distance each time it is rotated 90 degrees through the above-described method. The distance measuring sensor 91 measures distances when it rotates every 90 degrees, and measures distances in the x, y, x` and y` directions based on the first measurement. Specifically, the first shot is taken as x, and the third shot is taken at a position rotated 90 degrees counterclockwise with respect to x, and at a position rotated 90 degrees counterclockwise with respect to y and y taken secondly, Y` measured at the position rotated by 90 degrees counterclockwise with respect to the photographed x` and x` is measured, and the measured x, y, x` and y` are transmitted to the control unit 70 do. Here, x is an east direction, y is a north direction, x 'is a west direction, and y' is a south direction. to the next. The controller 70 receives distance measurement values x, y, x 'and y` for each direction and calculates an error distance compensation coordinate value using Equation (1).

Here, (-a, -b) is the error-distance compensation coordinate value.

For example, if the distance measurement value measured through the distance measuring sensor 91 is 80, and x 'is 120, y is 150, and y' is 50, Let's substitute in Equation 1. ((80) - (120)) / 2 = a and ((150) - (50)) 2 = b. Therefore, an error distance compensation coordinate value in which a is -20 and b is 50 can be calculated. Based on the error compensation coordinate values output to the display unit 80, the user moves the jetting unit 10 by 20 in the x 'direction on the basis of (-20, 50) and moves the jetting unit 10 by 50 distances in the y- 10 can be moved to the center axis of the air conditioner so that the central axis can be aligned. The error distance compensation coordinate value calculated by the control unit 70 based on the distance measurement sensor 91 and the measured distance value may be determined by taking a reference in any direction without generating a separate reference to the ceiling air conditioner The center of the air conditioner can be made to coincide with the center of the jetting unit 10 through the above-described equation (1).
