  An embodiment of a wet and dry vacuum cleaner with a cleaning function of the present invention will be described with reference to the drawings. 1 and 2 show a first embodiment of the present invention, in which the nozzle is immersed in the cleaning liquid, and FIG. 1 is a cross-sectional view of the electric vacuum cleaner of the present invention when the cleaning liquid is not sent. FIG. 2 is a cross-sectional view of the vacuum cleaner of the present invention when the cleaning liquid is sent. 3 and 4 show a second embodiment of the present invention. FIG. 3 is a sectional view of the electric vacuum cleaner of the present invention when the nozzle is not immersed in the cleaning liquid, and FIG. FIG. 4 is a cross-sectional view of the vacuum cleaner of the present invention when the cleaning liquid is sent. FIG. 5 is a top view of the vacuum cleaner of the present invention.

  Next, a first embodiment of the wet & dry vacuum cleaner with a cleaning function of the present invention will be described with reference to FIGS. In the figure, 1 is a vacuum cleaner body, 2 is an electric blower including a motor, 3 is a hose, 4 is a dust filter, 5 is an exhaust port, 6 is an exhaust port shutter, 7 is a cleaning liquid tank, 8 is a cleaning liquid, 9 is a tube, 10 is a nozzle, 11 is a dust collection chamber, 12 is a sewage collection tank, 13 is a cylindrical body, and 14 is a floater floater.

  FIGS. 1 and 2 show a case in which the nozzle 10 is immersed in a cleaning liquid 8 that does not cause foaming. The main body 1 of the cleaner is composed of a dust collection chamber 11 and an electric blower 2 that communicate with the intake port, and is connected to the hose 3 in an airtight manner. The dust containing moisture together with the air sucked from the hose 3 airtightly connected to the air inlet of the cleaner body 1 using the floor suction tool 16 for sucking the dust on the floor is along the flow path indicated by the arrow. Then, the dust is collected by the built-in dust filter 4 while being rotated in the dust collecting chamber 11.

  The remaining moisture from which the dust has been removed is stored in a sewage collection tank 12 installed at the entrance front of the electric blower 2. A cylindrical body 13 is provided in the center of the inside of the sewage collecting tank 12, and a floater 14 is installed as a floater that is operated up and down according to the level of sewage that is sucked into the cylindrical body 13 and stored. 14 rises when the amount of sewage in the sewage collection tank 12 increases, and is configured to block the inlet of the electric blower 2 so as to prevent the sewage from entering the electric blower 2.

  In addition, when the amount of sewage in the sewage collection tank 12 reaches a certain level, the sound of the floater 14 of the levitation body or the sensing means (not shown) provided in the cylindrical body 13 is activated to allow the user to sew the sewage in the sewage collection tank 12. A function for informing the user to remove the image may be provided.

  The exhaust from the electric blower 2 further proceeds as indicated by the flow path indicated by the arrow, and the exhaust is supplied by the nozzle 10 which is a means for supplying exhaust to the cleaning liquid tank 7 provided in the cleaner body 1. Thus, by increasing the pressure in the cleaning liquid tank 7, the cleaning liquid 8 in the cleaning liquid tank 7 is supplied to the spray nozzle 17, which is a spraying means provided in the floor suction tool 16, by means of the tube 9 that pushes and supplies the cleaning liquid 8. This makes it possible to supply cleaning water to a portion that needs to be pretreated with a cleaning liquid in advance, such as a floor or a carpet, without providing a special pump.

  The cleaning liquid tank 7 is formed in an airtight manner except for the supply port of the nozzle 10 which is a means for supplying exhaust gas and the outlet of the tube 9 which is a supply means for the cleaning liquid 8 so as not to let air pressure escape. An exhaust port shutter 6 is provided at the inlet of the cleaning liquid tank 7 to adjust the distribution of the exhaust amount to the cleaning liquid tank 7 and the exhaust amount to the exhaust port 5. Adjustment of the push-out amount of the cleaning liquid 8 is performed by opening and closing the exhaust port shutter 6 to adjust the exhaust amount of the exhaust gas.

  The adjusting means for distributing the exhaust amount by the exhaust port shutter 6 will be described with reference to FIG. FIG. 5 shows a top view of the wet and dry vacuum cleaner with a cleaning function of the present invention. The exhaust port shutter 6 is configured to open / close and adjust the exhaust port 5 with a slide plate. In the figure, the exhaust port is formed in a slit shape, thereby rectifying the exhaust gas and smoothing the flow of the exhaust gas to the cleaning liquid tank 7, but other means can be adopted without being limited to the slit shape.

  FIG. 1 shows an embodiment in which the nozzle 10 is immersed in the cleaning liquid 8 and the cleaning liquid 8 is not sent to the spray nozzle 17 which is an injection means provided in the floor suction tool 16. In this case, the exhaust port shutter 6 is widely open, the exhaust amount to the exhaust port 5 is almost, and the exhaust amount to the cleaning liquid tank 7 is zero or a small amount. Therefore, the exhaust pressure in the cleaning liquid tank 7 does not increase, and the cleaning liquid 8 is not supplied to the spray nozzle 17 provided in the floor suction tool 16 through the tube 9 for extruding and supplying the cleaning liquid 8.

  FIG. 2 shows an embodiment in which the nozzle 10 is immersed in the cleaning liquid 8 and the cleaning liquid 8 is sent to the spray nozzle 17 which is an injection means provided in the floor suction tool 16. In this case, the exhaust port shutter 6 is operated in the closing direction. It should be noted that when the exhaust outlet shutter 6 is completely closed, air passing through the motor in the electric blower 2 is lost and the motor is overheated. Therefore, the exhaust outlet shutter 6 is somewhat required for cooling. It needs to be open. In this state, the exhaust amount to the exhaust port 5 is small, and the exhaust amount to the cleaning liquid tank 7 increases. Therefore, the exhaust pressure in the cleaning liquid tank 7 increases and can be supplied to the spray nozzle 17 provided in the floor suction tool 16 through the tube 9 for extruding and supplying the cleaning liquid 8.

  Next, FIG. 3 and FIG. 4 show a second embodiment of the wet and dry vacuum cleaner with a cleaning function of the present invention. 3 and 4 show the case where the nozzle 10 is not immersed in the cleaning liquid 8 in which foaming occurs because the cleaning liquid in which foaming occurs is used. In the figure, the same reference numerals are assigned to the same components as those in FIGS. In addition, since the main operation is the same as that described with reference to FIGS. 1 and 2, only different points will be described here.

  The reason why the nozzle 10 is not immersed in the cleaning liquid 8 causing foaming is that when the nozzle 10 is immersed in the cleaning liquid 8 causing foaming, the cleaning liquid 8 is foamed by exhaust, and the floor suction tool 16 is supplied through the tube 9 that pushes out the cleaning liquid 8. This is because an appropriate supply cannot be made to the spray nozzle 17 provided in the above.

  FIG. 3 shows an embodiment in which the nozzle 10 is not immersed in the cleaning liquid 8 and the cleaning liquid 8 is not sent to the spray nozzle 17 which is an injection means provided in the floor suction tool 16. In this case, the exhaust port shutter 6 is widely opened, the exhaust amount to the exhaust port 5 is almost, the exhaust amount to the cleaning liquid tank 7 is zero or small, and the exhaust pressure does not increase.

  FIG. 4 shows an embodiment in which the nozzle 10 is not immersed in the cleaning liquid 8 and the cleaning liquid 8 is sent to the spray nozzle 17 which is an injection means provided in the floor suction tool 16. In this case, the exhaust port shutter 6 is operated in the closing direction. As a result, the exhaust pressure of the cleaning liquid tank 7 increases.

  Normally, when using a wet and dry vacuum cleaner with a cleaning function, spray the cleaning liquid on the floor or carpet in advance, and then inhale dust mixed with dust and moisture. After doing so, it is common to move to the operation of FIG.
