A vacuum cleaner that includes a first cleaner module and a second cleaner module that is removably coupled to the first cleaner module. The first cleaner module includes a first body and a first dust collection unit, and the second cleaner module includes a second body and a second dust collection unit. Thus, when done in an upright mode, cleaning can be done with a sufficiently great suction force. When done in a handy mode after the second cleaner module is separated, cleaning can be easily done using the second cleaner module.

Vacuum cleaner

The present disclosure relates to a cleaner improving the cleaning efficiency. The cleaner includes a main body, a suction device configured to suck foreign substances on a surface to be cleaned, and an extension member positioned in the rear of the suction device to connect the main body and the suction device, wherein the suction device includes a suction head including a suction port, a connection member connecting the suction head and the extension member, and a weight accommodated in the suction device and disposed between the suction port and the extension member such that the suction port is prevented from being lifted from the surface to be cleaned when the suction device moves along the surface to be cleaned.

Cleaner

Disclosed herein is a cleaner with improved cleaning efficiency. A cleaner includes a main body having a dust collecting unit and a suction head including a head cover, a base plate having a suction port to suck in foreign substances on a surface to be cleaned and coupled to the head cover, and a brush rotatably provided between the head cover and the base plate, wherein the base plate includes a first inclined portion slantly extending from a front end of the suction port with respect to the surface to be cleaned, and a second inclined portion slantly extending from a rear end of the suction port with respect to the surface to be cleaned, and integrally formed with the first inclined portion.

Provided are a plasma generating apparatus using mutual inductive coupling and a substrate treating apparatus including the same. According to an embodiment of the present invention, a plasma generating apparatus includes: an RF power supply providing an RF signal; a plurality of electromagnetic field applying units inducing an electromagnetic field by receiving the RF signal; and a reactance element connected to a ground terminal of the electromagnetic field applying unit, wherein each of the electromagnetic field applying units may include a plurality of mutually-inductively coupled coils.

Plasma generating apparatus using mutual inductive coupling and substrate treating apparatus comprising the same

Provided is a plasma generating device. The plasma generating device includes: an RF power supply providing an RF signal; a plasma chamber providing a space where gas is injected to generate plasma; a first electromagnetic inducer installed at one portion of the plasma chamber and inducing an electromagnetic field in the plasma chamber as the RF signal is applied; a second electromagnetic inducer installed at another portion of the plasma chamber and inducing an electromagnetic field in the plasma chamber as the RF signal is applied; a first load connected to the first electromagnetic inducer; a second load connected to the second electromagnetic inducer; and a controller controlling a power supplied to the first electromagnetic inducer and the second electromagnetic inducer by adjusting at least one impedance of the first load and the second load.

Plasma generating device, method of controlling the same, and substrate processing device including the plasma generating device

A vacuum cleaner that includes an upright main body, an upright fan motor generating a suction force, and a wheel assembly that is mounted on the upright main body and guides movement and rotation of the upright main body. The upright main body includes a first housing that is installed on the wheel assembly so as to be rotatable in a leftward/rightward direction, and a second housing that is installed in the first housing so as to be rotatable in a forward/backward direction. The vacuum cleaner can be moved and rotated by freely moving an extension frame extending upward from the second housing in forward, backward, leftward, and rightward directions.
