The present invention relates to a vacuum cleaner, and in particular, the cleaning method by steam spraying to sterilize the bottom surface of the cleaning target with steam of high temperature, high pressure, to improve the hygiene environment, and to collect the dirt to improve the cleaning efficiency; It relates to a vacuum cleaner.

The vacuum cleaner generally used sucks dirt into the suction port together with suction air by the suction power of the drive motor installed inside the main body, collects the suction air and the dirt into the dust collecting chamber of the main body through the extension pipe and the connection hose, Exhaled air is passed through the outside of the main body.

However, in the general vacuum cleaner as described above, as a structure for simply collecting dirt by suction force driven by the drive motor, there was a disadvantage in that it is not sanitary due to the sterilization of bacteria on the floor to be cleaned, and also the floor surface. If there is dirt, etc., there are various problems such as the cleaning efficiency is lowered because the suction force by the driving motor fails to collect the dirt effectively.

An object of the present invention is to provide a cleaning method and a vacuum cleaner by steam injection to solve various problems as described above.

Another object of the present invention to provide a cleaning method and a vacuum cleaner by steam injection to improve the sanitary environment by sterilizing the bottom surface to be cleaned.

Still another object of the present invention is to provide a cleaning method and a vacuum cleaner by steam spraying to improve cleaning efficiency by calling and collecting dirt attached to the floor.

In order to achieve the object of the present invention as described above, by using a high-temperature, high-pressure steam to sterilize the floor to be cleaned to improve the hygienic environment, and by collecting the steam vapor spraying to improve the cleaning efficiency There is provided a cleaning method and a vacuum cleaner.

Hereinafter, the present invention will be described in more detail.

The cleaning method according to the steam spray of the present invention sprays steam having a temperature of at least 100 ° or more and a pressure of 2 bar or more to the floor to be cleaned, thereby killing various bacteria and insects, and cleaning the dirt stuck to the floor to be cleaned. After being called instantaneously, the roller-type cleaning member is rotated to rub the floor to be cleaned, and to suck various kinds of dirt on the floor to be cleaned by vacuum pressure.

An embodiment of a vacuum cleaner for implementing a cleaning method by steam injection as described above will be described with reference to the accompanying drawings.

1 is a side view of a vacuum cleaner equipped with a steam spraying function according to the present invention, and FIGS. 2 and 3 are side and front views showing a steam generator which is a main component of a vacuum cleaner having a steam spraying function according to the present invention. 4 is a cross-sectional view taken along the line AA of FIG. 2, FIG. 5 is a cross-sectional view taken along the line BB of FIG. 2, and FIG. 6 is a circuit diagram of a vacuum cleaner having a steam spraying function according to the present invention. As shown in the drawing, the vacuum cleaner according to the present invention includes a cleaner main body 1, a suction port 2 provided below the main body 1, and a steam generating unit integrally formed with the main body 1. It consists of (3).

The main body 1 has an electric motor 4 installed therein to generate suction force, a dust collecting chamber 5 for collecting various dirt sucked through the suction port 2 by the driving of the electric motor 4, and a power source. The handle 6 is provided with a wire 6 for the supply of.

The suction port 2 is provided with wheels 8 and 9 at the front and rear, and inside the roller-type cleaning member 10 is connected to the electric motor 11 and the belt 12, the dust collecting chamber 5 ) Is connected to the duct 13 so that the dirt sucked by the suction force driven by the electric motor 4 is collected into the dust collecting chamber 5 through the duct 13.

The steam generator 3 is generated by the box 21 fixed to the back of the main body 1, the steam generator 22 accommodated in the box 21, and the steam generator 22 A steam hose 23 for supplying the vapor to the lower surface of the suction port 2 and a steam nozzle 24 connected to the end of the steam hose 23 for injecting steam to the floor to be cleaned.

The steam generator 22 is a top, bottom tank is fixed by a few bolts 31 and nuts 32 and filled with water for steam generation as shown in Figures 2 to 5 (33) (34), an electric heater (sheath pipe heater 35) which is installed at the bottom of the lower water tank 24, and both ends protrude to the side wall, and the electric heater (35) protrudes Packings 36 and 36 coupled to both sides of the lower water tank 34 to maintain airtightness, and fastening nuts 38 and 38 screwed to guide pieces 37 and 37 formed around the packing 36 and 36; Insulators 39, 39, washers 40, 40, and nuts, which are sequentially coupled to the electric heater 35 protruding into the fastening nuts 38, 38, perform the functions of insulation and power connection. 41) and 41, a stopper 42 coupled to the upper side of the upper tank 33, and a solenoid valve 43 installed in the upper tank 33 to regulate the supply of steam.
