The cleaning suction port 6a is formed on the peripheral side surface of the cleaner main body 1 at a position deviated from the lower surface when used as an air cleaner on the surface of the cleaner main body 1. ing. For this reason, even if the cleaner main body 1 is placed vertically, the suction of the air is not hindered by the floor F in the cleaning suction port 6a.

When used as an air purifier, there are two modes, a silent mode for purifying air in a quiet state during sleep or the like and a rapid mode for purifying indoor air in a short time. is there. First, when used in a silent clean mode, the plug of the power cord 9a is connected to an outlet, and a valve switching switch of the operation switch 113 is operated to control the switching valve 90 in the counterclockwise direction by the control means 65. The valves 91 and 92 are operated so as to close the through-hole 25a by rotating, and also to open the through-hole 26a, and the switch for starting and stopping the operation switch 113 is closed.

Then, the cleaning electric blower 70 is driven, and the air to be cleaned in the room is sucked from the cleaning suction port 6a, the filter device 5 and the suction port 4a formed in the lid frame 6, and the suction port 31, the cleaning After passing through the electric blower room 30, it flows into the installation room 40 from the outlet 33 and is discharged into the room through the cleaning filter 48. Then, large dust is removed from the air to be cleaned by the filter device 5 and fine dust is removed when passing through the cleaning filter 48 to be cleaned and discharged indoors. When the air to be cleaned flows into the installation chamber 40 from the cleaning electric blower chamber 30 through the discharge port 33, the valve 34 opens clockwise due to the wind pressure of the air to be cleaned. Since the valve 24 is rotated in the clockwise direction by its own weight to close the discharge port 23, the air to be cleaned is not supplied to the electric blower chamber 2 for dust collection.
0, it can be prevented from flowing out to the outside via the suction hose 14a through the dust collection chamber 10 and the like, so that all the air to be cleaned can be reliably cleaned.

In the case of using in the rapid cleaning mode, the valve switch 90 of the operation switch 113 is operated and the valve means 90 is rotated counterclockwise by the control means 65 so that the valve 91 is rotated.
The through hole 25a is opened by the valve 92 and the through hole 26a is opened by the valve 92. Then, the operation switch 113 for starting and stopping is closed. Then, the dust collecting electric blower 60 is driven, and the air to be cleaned is supplied to the cleaning suction port 6a, the filter device 5, the suction port 4a, the second air path 8, the through hole 26a, the dust collecting electric blower 60, and the discharge port. 23, the air is exhausted from the exhaust port 47 through the cleaning filter 48 through the installation chamber 40. When the clean air flows through the outlet 23, the valve 24 rotates counterclockwise by the pressure of the exhaust air to open the outlet, and the valve 34 rotates counterclockwise by its own weight. Since the outlet 33 is closed, all the air to be cleaned passes through the cleaning filter 48. At this time, fine dust contained in the air to be cleaned is removed, and the air cleaned from the outlet 47 is removed. Is discharged.

In this rapid cleaning mode, the air to be cleaned is sucked and cleaned by the dust collecting electric blower 60 having a large suction capacity, so that the indoor air can be cleaned in a short time. At this time, since the discharge port 33 of the cleaning electric blower chamber 30 is closed by the valve 34, the air to be cleaned sucked by the dust collecting electric blower 60 is supplied to the second air path 8 and the dust collecting electric blower. Air blower room 20, outlet 23,
The flow is prevented from flowing back into the second air passage 8 through the disposition chamber 40, the discharge port 33, and the electric blower chamber 30 for cleaning, and thus the cleaning operation is performed efficiently.

When the vacuum cleaner is used as an air purifier as described above, the main body 1 of the vacuum cleaner is used vertically. That is, when the vacuum cleaner is used as an air cleaner, the cleaner body 1 is arranged differently from the case where the cleaner body 1 is used as a vacuum cleaner in which the cleaner body 1 is placed horizontally. You can clearly recognize that you are using it as a machine. Therefore, when the cleaner is used as an air cleaner, a person does not accidentally move from one place where the cleaner body 1 is arranged to another place. In addition, it is possible to prevent an undesired situation such as a child or the like straddling and damaging the cleaner body 1.

When the cleaner body 1 is installed vertically and used as an air cleaner, the operation of the changeover switch 116 enables the operation of the air cleaner only when the cleaner body 1 is installed vertically. Become. When the cleaner main body 1 falls down from a vertically placed state due to a person accidentally kicking off, the operator 116a of the changeover switch 116 moves toward the outside of the cleaner main body 1 and the changeover switch 11 is moved.
6 is turned off. Therefore, the drive circuit of the cleaning electric blower 70 is opened, and the cleaning electric blower 70 is stopped. The operation of the changeover switch 116 disables the operation of the air purifier, thereby preventing the cleaner from becoming in a dangerous state that may cause a disaster due to the fall of the cleaner body 1. In particular, when the cleaner main body 1 is placed vertically, this mechanism is effective because the arrangement of the cleaner main body 1 is unstable compared to the case where the cleaner main body 1 is placed horizontally.

Further, when the cleaner body 1 is installed vertically and used as an air cleaner, the operation switch 113 is located on the upper surface of the cleaner body 1, so that the cleaner body 1 can be operated from the upper side. By operating the switch 113, the operation of the air purifier can be easily performed according to the arrangement of the cleaner body.

The present invention is not limited to the above-described embodiment, but can be implemented with various modifications. The configurations of the vacuum cleaner and the air cleaner provided in the vacuum cleaner can be variously modified without being limited to the above-described embodiments.
