However, since the size or shape of an indoor space in which the air cleaner is operated varies greatly, the operating efficiency of the air cleaner significantly decreases, and the air pollution levels are different for each area in the indoor space, which reduces the satisfaction of the consumer. In addition, a user needs to manually replace consumables such as a filter at regular intervals to maintain full functionality of the conventional air cleaner, but there is a problem in that frequent replacement of consumables is required in areas with high population density or high air pollution level.
Meanwhile, as human mobility gradually increases with the globalization of the world, harmful viruses are spreading rapidly with humans as intermediaries. Accordingly, social distancing measures are being practiced on national levels, and disinfection operations of periodically sanitizing or disinfecting individual homes or highly trafficked facilities are being practiced on individual or company levels.
In a conventional disinfection operation, a method in which a worker travels to an area that needs to be sanitized or disinfected and manually sprays chemicals while holding a tank where the chemicals are received is being mainly used. However, in addition to the potential adverse effect of the odor and residual substances of the chemicals on the health of the worker, there is a problem that it is difficult to manage a workforce in terms of time and cost because a large number of workers need to be secured.
Therefore, it is an aspect of the present disclosure to provide an air cleaning and disinfection robot and a method of operating the same, which are capable of stably performing air cleaning and disinfection operations even in spaces having various sizes and shapes.
It is another aspect of the present disclosure to provide an air cleaning and disinfection robot and a method of operating the same, which are capable of improving the accuracy and efficiency of air cleaning and disinfection operations.

In contrast, when the driving unit 110 and the air conditioning module 120 intend to be separated, after the driving unit 110 and the air conditioning module 120 approach the unoccupied mounting space 135 on the main frame 131, the second docking member 144 is elevated by the elevating and lowering device 149 to elevate the air conditioning module 120 from the driving unit 110 before the driving unit 110 and the air conditioning module 120 enter the detachable space 136 and the mounting space 135. Then, the driving unit 110 and the air conditioning module 120 enter the detachable space 136 and the mounting space 135, and the second docking member 144 is lowered by the elevating and lowering device 149, so that the air conditioning module 120 is caught, supported, and mounted on the mounting frame 132, and simultaneously the driving unit 110 and the air conditioning module 120 can be separated.
Meanwhile,
The detection unit 150 is provided to detect and recognize an operation environment of the target space. The detection unit 150 may be mounted inside the driving unit 110 and may detect the operation environment through an opening formed on one side of the housing.

However, this is an example to assist in the understanding of the present invention, and it is of course understood that various types of sensors may be employed as long as they are capable of detecting the operation environment of the target space. The environmental recognition unit and the pollution detection unit may transmit the detected and recognized information to the controller, and the controller may control operations of the driving unit 110, the air conditioning module 120, and the docking unit 140 based on the information obtained by the environmental recognition unit and the pollution detection unit.
Hereinafter, a method of operating the air cleaning and disinfection robot 100 according to the present embodiment will be described.
Before the purification device 121 and the driving unit 110 enter the unoccupied mounting space 135 and detachable space 136, the controller operates the elevating and lowering device 149 of the docking unit 140 to elevate the purification device 121 from the driving unit 110 so that the purification device 121 can stably enter and be mounted in the mounting space 135 on the upper side of the mounting frame 132 (see
With the purification device 121 elevated from the driving unit 110 by the docking unit 140, the controller allows the driving unit 110 to enter the unoccupied mounting space 135 and detachable space 136 (see
Then, the controller may operate the driving unit 110 to be departed from the corresponding detachable space 136 (see
The same above may be applied to an operation after the disinfection device 125 and the driving unit 110 are coupled to perform a disinfection operation of the target space.
While the disinfection device 125 and the driving unit 110 are coupled to perform an operation to disinfect harmful viruses in the target space, when it is determined that the replenishment of the disinfectant or the replacement of the disinfection device 125 is necessary because a level of the disinfectant received in the storage tank of the disinfection device 125 is lower than a preset level, when it is determined that a sufficient disinfection operation has been performed because an operating time of the disinfection device 125 exceeds a preset time, or when an operation switch signal is received from a user, the controller allows the driving unit 110 to approach toward the unoccupied mounting space 135 and detachable space 136 on the station 130.
Before the disinfection device 125 and the driving unit 110 enter the unoccupied mounting space 135 and detachable space 136, the controller operates the elevating and lowering device 149 of the docking unit 140 to elevate the disinfection device 125 from the driving unit 110 so that the disinfection device 125 can stably enter and be mounted in the mounting space 135 at the upper side of the mounting frame 132.
With the disinfection device 125 elevated from the driving unit 110 by the docking unit 140, the controller allows the driving unit 110 to enter the unoccupied mounting space 135 and detachable space 136, and operates the elevating and lowering device 149 of the docking unit 140 to lower the second docking member 144, thereby mounting the disinfection device 125 on the mounting frame 132 and simultaneously separating the driving unit 110 from the disinfection device 125.
Then, the controller may operate the driving unit 110 to be departed from the corresponding detachable space 136, and allow the driving unit 110 to access and move to the detachable space 136 at the lower side of the mounting space 135 where the disinfection device 125 or the purification device 121 in standby for operation is mounted, and may operate the elevating and lowering device 149 of the docking unit 140 to couple the disinfection device 125 or the purification device 121 in standby for operation to the driving unit 110 to perform subsequent operations in succession.
Hereinafter, an operation of the discharge port 122 or the spray port 126 of the air conditioning module 120 according to the present embodiment will be described.
Referring to
Then, the controller may rotate and adjust the discharge port 122 or the spray port 126 of the air conditioning module 120 toward a relatively wide area or an area with a large amount of harmful substance C so that the air conditioning module 120 can efficiently and quickly proceed with the air purification or disinfection operation, and the controller may rotate the discharge port 122 or the spray port 126 of the air conditioning module 120 by steering the driving unit 110, or the discharge port 122 or the spray port 126 may be rotated through a motorized device mounted on the air conditioning module 120 itself. Further, when it is desired to perform a comprehensive operation over a wider area, or when it is determined that the driving unit 110 is difficult to access due to obstacles, the controller may elevate the discharge port 122 or the spray port 126 of the air conditioning module 120 to perform the operation.
The present disclosure has been described with reference to the limited embodiments and the drawings, but the present disclosure is not limited thereto. The described embodiments may be changed or modified by those skilled in the art to which the present disclosure pertains within the technical spirit of the present disclosure and within the scope equivalent to the appended claims.
