Description

TECHNICAL FIELD [0001] The present invention relates to a vacuum cleaner having a cord reel mounting and a vacuum cleaner,

[0001] The present invention relates to a vacuum cleaner and, in the case of a cordless cleaner, if the power cord is completely unscrewed from the cord drill and can not be further cleaned, The present invention relates to a vacuum cleaner for both wired and wireless, which can be conveniently cleaned to a remote place using a battery.

Generally, the vacuum cleaner is divided into a wire vacuum cleaner and a wireless vacuum cleaner.

In the case of a wire vacuum cleaner, when a cordless drill is installed, the power cord is plugged into an outlet, and the power cord is unscrewed and moved while being cleaned. Since the length of the cord wound on the cord drill is limited, In case of using, it can be used without any problem, but a problem arises when the power line is completely released from the cord drill and can not proceed any further.

That is, if the cord drill is loosened and can not be moved any further, go to the location of the outlet where the vacuum cleaner is plugged, remove the plug, insert the plug again into another outlet near the vacuum cleaner, There is a disadvantage that the operation is repeated several times.

On the other hand, in the case of a wireless vacuum cleaner, there is no limitation on the place where it can be used, but since the output depends on only the battery, the size (capacity) of the battery must be large. However, considering the convenience of the user, There is a limit to the use of heavy batteries.

Therefore, such a wireless vacuum cleaner can start to discharge from the moment of separation and can output a high output in the early stage of use, but the output will be reduced sharply. In particular, if a large space needs to be cleaned, There is a problem that the battery must be charged again during use.

In order to solve such a problem, a vacuum cleaner having both a wireless and a wireless connection has been proposed as in the prior art documents. The vacuum cleaner incorporates a built-in battery so that the user can clean the battery using the power source of the power line.

However, even if the conventional vacuum cleaner for both wireless and radio uses a general power source and the length of the power source line is short, the plug of the power source line must be disconnected from the outlet so that it can be used farther. There is a problem that it is inconvenient to return to the vacuum cleaner after removing the plug to the position and then to restart the cleaning again. This is followed by a waste of time and inconvenience to clean up next.
