As shown in Fig. 2, the cleaner body 1 is provided with a dust collecting chamber 2 for collecting dust. The dust collecting chamber 2 is connected to the intake air passage 3 via a vortex chamber (not shown), and the suction port body 4 is connected to the inlet of the intake air passage 3. Inside the cleaner body 1, a built-in suction drum is built in. The wind motor 5 is driven by receiving supply of electric power from the rechargeable battery 6. Moreover, the handle 7 is provided in the upper part of the cleaner body 1, and the terminal 8 is provided in the location below the dust collecting chamber 2. The terminal 8 is a portion for receiving the supply of electric power to charge the rechargeable battery 6 and is electrically connected to the charging stand 20 when the cleaner body 1 is placed on the charging stand 20.

In such a vertical electric vacuum cleaner, the user grips the handle 7 of the cleaner body 1 to sweep it. When the blower motor 5 is driven, the suction force acts on the intake air passage 3, and the dust is sucked together with the air from the suction port body 4. The inhaled air and dust pass through the intake air passage 3 and are then charged to the vortex chamber. In the vortex chamber, air and dust are separated, and only dust is collected in the dust collecting chamber 2.

Next, the configuration of the charging stand 20 will be described in more detail. Fig. 3 is a side view of the electric vacuum cleaner shown in Fig. 1. Further, Fig. 4 is a cross-sectional view showing the electric vacuum cleaner shown in Fig. 1 taken along the line A-A. Further, Fig. 5 is a perspective view of the charging stand shown in Fig. 1. Hereinafter, the configuration of the charging stand 20 will be described with reference to Figs. 1 to 4 as appropriate.

The charging stand 20 is composed of a seat portion 21 and a column-like pillar portion 22 that is erected on the seat portion 21 and supported. The cleaner body 1 is detachably mounted on the charging stand 20. In this case, the cleaner body 1 is erected and supported in a state before the suction port body 4 is placed in the seat portion 21. More specifically, the intake air passage 3 has a longitudinally long shape extending in the vertical direction in a state where the cleaner body 1 is erected, and is disposed along the pillar portion 22 in a state where the cleaner body 1 is placed on the charging stand 20. The intake air passage 3 is disposed in parallel on the side. In addition, the dust collecting chamber 2 is located at the upper portion of the intake air passage 3 in a state where the cleaner body 1 is erected, and is supported by the upper surface of the column portion 22 in a state where the cleaner body 1 is installed in the charging stand 20. support. The power transmission unit 23 is provided on the upper surface of the pillar portion 22, and is electrically connected to the terminal 8 described above. The cleaner body 1 performs charging operation of the rechargeable battery 6 using electric power supplied from the charging stand 20.

In the electric vacuum cleaner of the first embodiment, the air purifying function is mounted on the charging stand 20. That is, the intake port 25 is provided on the back side of the pillar portion 22 of the charging stand 20. Further, the exhaust ports 26 are respectively provided on both side faces of the seat portion 21 of the charging stand 20. The intake port 25 and the exhaust port 26 communicate with each other via the duct portion 27 formed in the internal space of the pillar portion 22 . Further, a louver 261 for adjusting the exhaust direction to be higher than the horizontal direction is provided at the opening of the exhaust port 26. Further, the duct portion 27 located inside the seat portion 21 is provided with a fan 28 for taking in air from the intake port 25 and exhausting it to the exhaust port 26. Further, a filter 29 through which the air taken in by the intake port 25 passes is provided in the duct portion 27. The filter 29 is for purifying the air taken in from the suction port 25.

In such a configuration, when the fan 28 is driven, the outside air is taken in from the intake port 25 and purified by the filter 29. The purified air passes through the duct portion 27 and is discharged from the exhaust port 26 to the external space. When the vacuum cleaner body 1 is used for cleaning, the dust is scattered in the air. According to the electric vacuum cleaner of the first embodiment, the dust that is scattered by the use of the electric vacuum cleaner can be removed by the air purifying function of the charging stand 20, so that the cleaned air can be effectively purified.

Further, according to the electric vacuum cleaner of the first embodiment, when the filter 29 is dirty, the filter body 29 can be cleaned using the cleaner body 1. Therefore, it is not necessary to separately prepare a cleaner for cleaning the filter 29, and the usability is improved. Further, in general, dust is easily accumulated around the air cleaner due to the influence of the air flow, but the electric vacuum cleaner according to the embodiment does not have to be separately prepared. The vacuum cleaner, and using the cleaner body 1, can simply sweep the periphery of the charging stand 20 having the air purifying function.

Further, in the electric vacuum cleaner of the first embodiment, the intake port 25 is disposed above the exhaust port 26. According to this configuration, since the air away from the floor surface is sucked, the pollen or the like attached to the clothes or the like can be effectively sucked.

Further, in the electric vacuum cleaner of the first embodiment, when the cleaner body 1 is placed on the charging stand 20, the intake air passage 3 of the cleaner body 1 is configured to be parallel to the duct portion 27 of the charging stand 20. That is, the direction of the air passage of the duct portion 27 and the direction of the air passage of the intake air passage 3 become parallel. According to this configuration, since the elongated air passages can be arranged in close contact, the space efficiency can be maximized.

Further, in the electric vacuum cleaner of the first embodiment, the filter 29 is disposed inside the pillar portion 22, and the fan 28 is disposed inside the seat portion 21. Since the fan 28 having a heavier weight than the filter is disposed below the filter 29, the charging stand 20 can be made lower in centering and the stability is improved.

Further, in the electric vacuum cleaner according to the first embodiment, the exhaust direction from the exhaust port 26 is set to be higher than the horizontal direction. According to this configuration, the dust accumulated on the floor surface is not raised, and the clean air is released into the indoor space.

In the electric vacuum cleaner of the first embodiment, the intake port 25 is provided in the pillar portion 22, and the exhaust port 26 is provided in the seat portion 21, whereby the intake port 25 is disposed in the specific exhaust port. 26 is above. However, the arrangement of the intake port 25 and the exhaust port 26 is not limited to this, and the intake port 25 may be provided. In the seat portion 21, the exhaust port 26 is provided in the pillar portion 22, whereby the intake port 25 is disposed below the exhaust port 26. In such a configuration, for example, the air blowing direction of the fan 28 may be reversed. According to this configuration, the dust raised from the floor surface can be effectively sucked in and purified from the intake port 25 disposed in the seat portion 21.

Further, in the electric vacuum cleaner according to the first embodiment, the exhaust port 26 is provided on the side surface of the seat portion 21. However, the arrangement of the seat portion 21 is not limited thereto, and may be provided, for example, on the upper surface of the seat portion 21. Further, the back surface of the seat portion 21 is not suitable as an arrangement of the exhaust port 26. Since it is assumed that the back side of the seat portion 21 is in close contact with the wall, the exhaust port is plugged in this case. Moreover, even if it is not in close contact with the wall, if the exhaust continues to collide with the wall, the wall may be contaminated. Therefore, when the exhaust port 26 is disposed on the side surface or the upper surface of the seat portion 21, the angle of the louver 261 is set such that the exhaust direction is the side or the front side, that is, the exhaust direction is preferably not the rear surface direction.

Further, in the electric vacuum cleaner of the first embodiment, a cyclone type electric vacuum cleaner including a vortex chamber has been described, but the type of the electric vacuum cleaner is not limited thereto. In other words, as long as it is a vertical vacuum cleaner having a charging stand, it may be a paper bag type electric vacuum cleaner.
