Description

Cleaner {A CLEANER}

The present invention relates to a cleaner, and more particularly, to a cleaner capable of automatic cleaning and manual cleaning.

In general, the cleaner includes a cleaner body having a suction device and a dust container, and a cleaning nozzle connected to the cleaner body to perform cleaning in a state close to the surface to be cleaned.

The cleaner is divided into a manual cleaner which the user directly cleans the surface to be cleaned, and an automatic cleaner which cleans the surface to be cleaned while the cleaner body itself runs.

In the manual cleaner, the suction device generates the suction force by the driving force of the electric motor, and when the user puts the cleaning nozzle on the cleaning surface while holding the cleaning nozzle or the cleaner body by hand, The cleaning nozzle sucks foreign matters including dust on the cleaning surface, and the sucked foreign matter is collected in the dust container, thereby cleaning the cleaning surface.

The automatic cleaner may further include an ultrasonic sensor and / or a camera sensor installed on the vacuum cleaner body including the suction device and the dust container, and the vacuum cleaner may be generated by the suction device while automatically driving around the cleaning surface. The cleaning nozzle sucks the foreign matter on the cleaning surface by the suction force, and the suctioned foreign matter is collected in the dust container, thereby cleaning the cleaning surface.

The cleaning nozzle used for the manual cleaner is moved to the surface to be cleaned by the user to be in close contact with the surface to be cleaned, but the cleaning nozzle used for the automatic cleaner is in close contact with the surface to be cleaned when it is coupled to the cleaner body. Is placed.

In addition, a wheel for driving the cleaner body is installed in the cleaner body of each of the manual cleaner and the automatic cleaner, and the wheel installed in the manual cleaner remains with the cleaner body on the floor when the user cleans. Easily dragged and carried, the wheel installed in the automatic cleaner rotates by the driving force of the electric motor and automatically drives the cleaner body.

In recent years, the development of the vacuum cleaner which can perform both automatic cleaning and manual cleaning is becoming active. However, since the cleaning nozzle used for the automatic cleaning is disposed in a state close to the bottom surface, which is the surface to be cleaned, when the user performs manual cleaning, the cleaning nozzle used for the automatic cleaning is pulled out due to a threshold or the like. Since there is a problem that it is difficult to carry, when the user wants to perform manual cleaning, it is necessary to remove the cleaning nozzle used for the automatic cleaning from the cleaner body, and replace it with a cleaning nozzle used for manual cleaning.

In addition, the cleaning nozzle used for the manual cleaning is formed to have a sufficient length so that the user can be cleaned while standing. However, when the cleaning nozzle used for the automatic cleaning is formed to have a long length, the cleaning area of the cleaner is inevitably narrowed, so that the length of the cleaning nozzle is shortened as much as possible. The overall length of should be short.

In order to shorten the overall length in the running direction of the cleaning nozzle and the cleaner body, there is a method of shortening the length of the connection flow path formed on the outer side of each of the cleaner body and the cleaning nozzle and connected to each other.

By the way, when the connection flow path is shortly formed, when the cleaning nozzle is coupled to the cleaner body, the connection flow path is positioned below the cleaner body, and does not protrude outward from the cleaner body. Therefore, if a stripping structure capable of removing the cleaning nozzle used for automatic cleaning from the cleaner body is installed in the connecting passage, the user may not only have to look under the cleaner body to find the stripping structure. There is a problem in that the sealing performance of the connection channel is lowered due to the removal structure installed in the connection channel.

The problem to be solved by the present invention, by installing a structure that can remove the automatic cleaning cleaning nozzle from the cleaner body in the automatic cleaning cleaning nozzle, it is possible to implement a vacuum cleaner capable of automatic cleaning and manual cleaning, from automatic cleaning to manual cleaning To provide a cleaner that can be easily converted.
