2. Description of the Related Art Conventionally, a service station or the like provides a service for cleaning the inside of a vehicle, and a service staff enters the vehicle and removes dust and dirt with a suction type vacuum cleaner.

However, dust and dirt that have entered the seat cloth and seams cannot be removed by simply sucking them, and if stains or the like are attached to the seat for eating and drinking in the vehicle, they are completely removed. It is not possible to do so, and improvement of service is required.

[0004]

Therefore, although a service such as spraying a detergent to wipe off the sheet etc. is added, the sheet portion gets wet because the detergent is a liquid,
Not only is it practical for cleaning at service stations, but it can also be used for cleaning office carpets.
The detergent locally wets the carpet, changing only the color of the carpet.

An object of the present invention is to provide a cleaning method using steam capable of performing a drying treatment on the spot, and to solve the above problems at once.

[0006]

According to the cleaning method using steam of the present invention, dust and dirt on the surface of the area to be cleaned are captured by air suction, and then the air suction is stopped to inject the steam to the area to be cleaned. It is characterized in that stains and dust on the area to be cleaned are exposed, and after the exposed body is wiped off, hot air is blown to the area to be cleaned for drying.

The multi-cleaner of the present invention comprises a vacuum cleaner having a filter and a fan interposed between the suction chamber and the blow-out chamber, and a steam supply device attached to the vacuum cleaner. The vacuum cleaner functions as a dryer by heating the air blown from the chamber with a heater.

[0008]

[Operation] After removing the main dust and dirt by air suction, steam is sprayed to the area to be cleaned, so spots and dust are exposed, wipe off the exposed body, blow warm air and dry the area. As a result, more complete cleaning can be realized without the presence of wet spots in the area to be cleaned.

It is an operation panel that controls the power supply control device 4 by buttons.

A steam supply device 3 is installed in the lower part of the vacuum cleaner 2, and the steam supply device 3 has a steam tank 19 having a water supply port 18 having a safety valve 17 in the upper part thereof and an electromagnetic valve for opening and closing the steam tank 19. A steam hose 21 controlled to open and close by a valve 20.
An outlet connection pipe 22 is formed at the tip of the. As shown in FIG. 2, a heater 23 for raising the water temperature is installed inside the steam tank 19, and a temperature sensor 24 for keeping a predetermined hot water temperature is adjacent to the heater 23.

Next, the cleaning procedure and the air flow will be described with reference to FIGS. 3 and 4. First, the power supply control chamber 4 will be described.
Turn on the main power switch of the operation panel 25 installed on the upper part. At this point, only the heater 23 in the steam tank 19 described later is turned on, the water is boiled, and the steam tank 19 is filled with high-pressure steam.

When the steam in the steam tank 19 reaches a predetermined pressure, the operation panel 25 displays a ready message. Receiving this display, the hose 27 having the nozzle 26 or the like at its tip is inserted into the suction connection port 5 in the middle stage, and the suction switch of the operation panel 25 is pressed. When the suction switch ON signal and the ON signal of the insertion switch 15 formed in the vicinity of the suction connection port 5 are transmitted to the control device 28 in the power feeding control chamber 4, a rotation signal is sent to the fan 13 and is shown in FIG. Air flows in the direction of the arrow, and the air is discharged from the outlet connection port 7.

The dust flowing in from the suction connection port 5 together with the air is heavier on the bottom of the suction chamber 6, and the light dust such as dust is filtered when it passes through the filter 10 together with the air. Further, the air passes through the communication hole 9 and the fan 13

Here, since the temperature sensor 24 operates in the steam tank 19, the temperature in the steam tank 19 does not rise rapidly, but the heater power is on even when the opening / closing solenoid valve 20 is closed. When the amount of steam in the steam tank 19 exceeds a predetermined amount, the safety valve 17 operates and the pressure can be adjusted by allowing the excess pressure to escape.

This steam has a high temperature, so that it can not only decompose the stains soaked into the cloth by spraying it on the cloth portion, but also dust and the like can be made to stand out together with the water and be exposed on the surface. The dust and the like floating here is wiped off together with water using a cloth or the like.

Next, since the wetness cannot be removed only by wiping with a cloth or the like, a drying operation is performed using a high temperature air blow.
Here, by inserting the hose 26 previously used for suctioning into the outlet connection 7 in the upper stage and pressing the warm air switch of the operation panel 25, the signal of the insertion switch 15 and the respective signals of the warm air switch are controlled. 28 and the signal for closing the opening / closing solenoid valve 20 together with the fan 13 and the heater 1
Power signals are sent to 6 and 6, respectively.

When the power of the heater 16 is turned on, the air that has passed through the fan 13 and is discharged is warmed when it further passes through the heater 16, and hot air is blown from the tip of the hose 26. Since this warm air dries the area to be cleaned that has been moistened by the steam, the wet spot disappears.

Continuing the use in this manner causes maintenance work such as replenishing the water in the steam tank 19, removing dust accumulated in the suction chamber 16, and replacing the filter 10. To use as a guide for work,
A level gauge (not shown) is attached to each, or other means such as a sensor is used to operate the operation panel 25.
By using a device for displaying the level on the display, more reliable maintenance can be performed.

As described above, by using the multi-cleaner 1, not only the dust is sucked and removed, but also the use of steam makes it difficult to wash the dust with water. It will be possible to clean the inside of the car in a more complete way.
