Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is installed in a gasoline filling station or the like, and relates to a cleaning device for a car interior.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a cleaning device for an interior of an automobile, a vacuum cleaner in which a vacuum generating device is disposed in a housing and a vacuum hose having an air nozzle at the tip is led out from the upper portion of the housing to suck up dust in the vehicle is used.
[0003]
In order to clean the seats in the car with this vacuum cleaner, after sucking up rough garbage with a vacuum hose, spraying a special detergent etc. or spraying steam with a heater type sprayer to lift up the dirt and wipe it off .
[0004]
[Problems to be solved by the invention]
However, when the special detergent is sprayed, if the wiping is insufficient, there is a problem that the occupant's clothes are soaked in the scent or the odor remains in the vehicle. In addition, since steam produced by the heater sprayer has large droplets, there is a problem that unwashed parts are generated.
[0005]
An object of the present invention is to provide a cleaning device that eliminates the inconveniences of the above-described conventional example, and that can perform effective cleaning with a small amount of power consumption and spray of fine droplets on a sheet or the like in an automobile. There is.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an ultrasonic atomizing unit in which an ultrasonic vibrator is disposed inside a water storage tank on a movable carriage, and a water supply opening and a steam discharge opening are provided in the water storage tank. A vacuum hose unit provided with a suction hose with a suction nozzle attached to the tip and detachably connected to the suction port of the dust collecting tank, and provided with a discharge port, and the ultrasonic atomizing unit and the vacuum cleaner The gist is that a control unit for controlling the unit is placed on the water tank.
[0007]
According to the first aspect of the present invention, the driving of the ultrasonic vibrator in the ultrasonic atomizing unit gives ultrasonic vibration energy to the liquid, and the capillary surface wave and cavitation specific to the frequency on the liquid surface and inside the liquid. By generating the above, innumerable capillary surface waves are generated on the liquid surface, the surface tension of the liquid is reduced, and regular splitting is performed. Therefore, a fine droplet of steam is sprayed by ultrasonic waves and penetrates to every corner of a sheet or the like to improve the cleaning effect. In addition, less power is consumed than a heater-type sprayer.
[0008]
According to this invention of Claim 2, in addition to the said effect | action, an upper limit sensor and a lower limit sensor can detect that the water was put into the water tank too much or water shortage, and can alert | report it with an alarm device.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a partially cutaway side view showing an embodiment of the cleaning apparatus of the present invention, FIG. 2 is a perspective view of the same, 1 in the figure has a caster 2 on the lower surface of the framed main body, It is a cart provided with a handle 3 for pushing behind.
[0010]
A water tank 4 having a tank structure is installed on the carriage 1, a water supply port 5 and a steam discharge port 6 are provided in the water tank 4, and an ultrasonic transducer 7 a is provided therein to provide ultrasonic waves. An atomization unit 7 was obtained.
[0011]
In the water tank 4, an upper limit sensor 8 serving as a water level sensor is provided below the lower surface of the steam discharge port 6 in the water tank 4, and a lower limit sensor 9 serving as a water level sensor above the upper surface of the ultrasonic vibrator 7a. Attached.
[0012]
Further, on the water storage tank 4, a suction hose 11 having a suction nozzle 10 attached to the tip thereof is detachably connected to the suction port 12 of the dust collecting tank 13, and a vacuum type cleaning provided with a discharge port (blow) 14 is provided. A machine unit 15 and a control unit 17 for controlling the ultrasonic atomizing unit 7 and the vacuum cleaner unit 15 were placed.
[0013]
As shown in FIG. 3, the control unit 17 has various switches 16a to 16c such as a power source, steam, and a vacuum cleaner, an operation lamp 16 having a display lamp indicating ON / OFF of these switches, a full tank, and an empty display lamp 16e. In addition, although not shown in the figure, a control mechanism using a microcomputer, a voltage generation circuit including a transistor as an electric drive circuit for the ultrasonic transducer 7a, and a buzzer / sound alarm and the like are incorporated.
[0014]
In this way, the output signals of the upper limit sensor 8 and the lower limit sensor 9 of the ultrasonic atomizing unit 7 are introduced into the control unit 17 to operate the alarm.
[0015]
In use, the hose 18 provided with the nozzle 18a at the tip is connected to the steam discharge port 6 of the ultrasonic atomizing unit 7, and the suction nozzle 10 is attached to the tip of the suction port 12 of the vacuum cleaner unit 15. The suction hose 11 is connected and water is stored in the water storage tank 4 through the water supply port 5. When the water is excessively charged, the upper limit sensor 8 detects this and notifies the display lamp 16e or an alarm.
[0016]
In order to clean the inside seat of the automobile, the vacuum cleaner unit 15 sucks up dust as appropriate, and then operates the ultrasonic atomizing unit 7 to discharge steam from the nozzle 18a of the hose 18 and spray it. Remove dirt by brushing with neutral detergent or brush.
[0017]
The vacuum cleaner unit 15 is operated, the cleaning liquid or the like is sucked by the suction nozzle 10 of the suction hose 11, the second steam is sprayed, and the suction hose 11 sucks again.
[0018]
When the water in the water storage tank 4 is low, the lower limit sensor 9 detects this and notifies it with the display lamp 16e or an alarm.
[0019]
Although the above shows an example of how to use, the present invention is not limited to this, and appropriate use in combination of suction of the vacuum cleaner unit 15 and discharge of steam of the ultrasonic atomizing unit 7 is possible.
[0020]
【The invention's effect】
As described above, the cleaning apparatus of the present invention can perform effective cleaning with low power consumption by spraying fine droplets of droplets with ultrasonic waves onto a sheet or the like in an automobile.
