The cleaning operation unit faces the wall surface. In this state, the user is at a position where it is difficult for the user to operate the air cleaning operation unit. For this reason, when the user changes the direction of the main body case so that the air purifying operation unit can be easily operated, the peripheral side portion provided with the air purifying suction port is separated from the wall surface of the room and accordingly. Move to a position that does not face. Therefore, it is possible to avoid a situation in which the main body case is installed in a direction in which the portion of the peripheral side surface portion provided with the air cleaning suction port contacts the wall surface of the room. Thus, the air purifying suction port is not directly blocked by the wall surface of the room. That is, air can be sucked in from the air cleaning inlet at a position where the peripheral side surface portion of the main body case where the air cleaning inlet is provided does not face the wall surface of the room.

According to a second aspect of the present invention, there is provided a vacuum cleaner having an air purifying function, comprising: a main body case having a cleaning suction port, an air cleaning suction port, and an exhaust port; and the cleaning suction port provided inside the main body case. An electric blower that sucks air from the air cleaning suction port and discharges the air from the exhaust port; and a dust collection chamber that is provided inside the main body case and captures dust contained in the air sucked from the cleaning suction port.

That is, in a state where the electric cleaning fan 60 is driven and the electric air cleaning fan 70 is stopped,
The exhaust air from the cleaning electric blower 60 rotates the valve 24 in the counterclockwise direction to open the discharge port 23.
Since the exhaust port 33 is closed by its own weight, the exhaust air from the electric blower 60 for cleaning does not flow into the electric blower chamber 30 for cleaning. Also,
Conversely, when the electric blower for cleaning 60 is stopped and the electric blower for air cleaning 70 is driven, the valve 34 is rotated clockwise by the exhaust air from the electric blower for air cleaning 70 to open the discharge port 33. However, since the valve 24 keeps the outlet 23 closed by its own weight, the air to be cleaned by the air cleaning electric blower 70 does not flow into the cleaning electric blower room 30.

When the exhaust gas flows into the disposition chamber 40 when the valve 24 is opened, the pressure in the disposition chamber 40 increases. This pressure acts in the direction in which the valve 34 closes the discharge port 33. For this purpose, the valve 34 surely closes the discharge port 33 together with its own weight, and also when the valve 34 is opened and the air to be cleaned flows into the installation chamber 40, the pressure in the installation chamber 40 similarly increases. Therefore, since this pressure acts in a direction in which the valve 24 closes the outlet 23, the valve 24 surely closes the outlet 23 together with its own weight.

The air enters the installation chamber 40 via the cleaning electric blower 60 and the discharge port 23, passes through the air cleaning filter 48, and is exhausted from the exhaust port 47. When the exhaust air flows through the exhaust port 23, the valve 24 rotates counterclockwise due to the pressure of the exhaust air to open the exhaust port 23, and when the exhaust air passes through the air cleaning filter 48, the exhaust air is exhausted. Since fine dust contained in the wind is removed, the air exhausted from the exhaust port 47 is clean, so that sanitary cleaning can be performed. Further, since the exhaust air flowing out of the exhaust port 23 is closed by the valve 34, the exhaust air is not exhausted to the outside, that is, the room from the inside suction port 4a through the cleaning electric blower chamber 30. Therefore, all exhaust air containing fine dust is exhausted through the air cleaning filter 48, and sanitary cleaning can be performed from this point as well.

Next, a case where the air purifier is used will be described. When using as this air purifier,
There are two modes, a silent mode in which air is cleaned quietly during sleep or the like, and a rapid mode in which room air is cleaned in a short time. First, when used in a silent clean mode, the plug of the power cord 9a is connected to an outlet, and the changeover switch 104 is operated to operate the control device 6.
5, the switching valve 90 is rotated counterclockwise to
5a are closed and the valves 91 and 92 are operated so as to open the through hole 26a.
Drive switch 103 is closed. Then, the air purifying electric blower 70 is driven, and the air to be cleaned in the room is supplied to the air purifying inlet 6 a formed in the lid frame 6, the filter device 5.
Then, the air is sucked from the inner suction port 4 a, passes through the suction port 31 and the inside of the cleaning electric blower chamber 30, flows into the installation chamber 40 from the discharge port 33, and is discharged into the room through the air cleaning filter 48. Then, large dust is removed from the air to be cleaned by the filter device 5, and when passing through the air cleaning filter 48, the fine dust is removed to be cleaned and discharged indoors. The air to be cleaned is the electric blower room 3 for cleaning.
When the air flows into the disposition chamber 40 from the inside through the outlet 33, the valve 34 opens clockwise due to the wind pressure of the air to be cleaned. Further, 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 passes through the electric blower chamber 20 for cleaning, the dust collecting chamber 10, and the like, via the suction hose 14a. As a result, the air to be cleaned can be completely cleaned.

Next, when used in a rapid cleaning mode,
The selector switch 104 is operated to rotate the switching valve 90 in the counterclockwise direction by the control device 65, and the through hole 25 is
a and the through hole 26a is opened by the valve 92,
Next, the drive switch 10 of the electric blower 60 for cleaning
3 is closed. Then, the cleaning electric blower 60 is driven, and the air to be cleaned is supplied to the air cleaning suction port 6a, the filter device 5, the inner suction port 4a, the second air passage 8, and the through hole 2.
6a, electric blower 60 for cleaning, outlet 23, installation room 40
Then, the air is exhausted from the exhaust port 47 through the air cleaning filter 48. 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 of the air to be cleaned passes through the air cleaning filter 48. At this time, fine dust contained in the air to be cleaned is removed, and Is discharged.

In this rapid cleaning mode, the air to be cleaned is sucked and cleaned by the cleaning electric blower 60 having a large suction capacity, so that the indoor air can be cleaned in a short time. At this time, the cleaning electric blower room 3
Since the discharge port 33 of the cleaning air blower is closed by the valve, the air to be cleaned sucked by the electric blower for cleaning 60 passes through the electric blower chamber for cleaning 30 and the second air passage 8 again, and the electric air for cleaning again. Flowing into the machine room 20, that is, through the second air passage 8, the cleaning electric air blower room 20, the outlet 23, the arrangement room 40, the outlet 33, and the cleaning electric blower room 30 again, It is prevented from flowing back to the air passage 8 and returning.

When performing air cleaning, the purified air is supplied to an exhaust port 47 provided on the upper surface 1a of the main body case 1.
The air to be cleaned is discharged upward, and the air to be cleaned is sucked through the air cleaning inlet 6a formed in the peripheral side surface 1c of the main body case 1, so that the air inside the room can be circulated and efficiently cleaned.

This vacuum cleaner has the following features. That is, the air purifying suction port 6a is formed in the peripheral side surface portion 1b of the main body case 1, and the operation switches 103 to 106 serving as the air purifying operation section and the display are provided near the air purifying suction port 6a of the main body case 1. Part 107

For this reason, as shown in FIG. 5, when the main body case 1 is installed in such a direction that the peripheral side surface formed with the air purifying suction port 6a is in contact with the wall surface P of the room, it is provided near the air purifying suction port 6a. The operation unit for air cleaning faces the wall. In this state, the air purifying operation switches 103 to 10 are operated by the user.
6 is very difficult to operate, and the display units 107 to 110
Is in a position where it is very difficult to see. For this reason, when the user changes the direction of the main body case 1 so that the user can easily operate the air purifying operation section, the main body case 1 is accordingly moved to the peripheral side surface portion 1c where the air purifying suction port 6a is formed. The user moves away from the wall surface P of the room to a position not facing the room. Accordingly, it is possible to prevent the main body case 1 from being installed in a direction in which the peripheral side surface portion on which the air cleaning suction port 6a is formed contacts the wall surface P of the room. Thus, the air cleaning inlet 6a of the main body case 1 is not directly blocked by the wall surface P of the room. That is, the air cleaning inlet 6 of the main body case 1
The air can be sucked in from the air cleaning inlet 6a at a position where the portion of the peripheral side surface portion 1c provided with a does not face the wall surface P of the room. Therefore, the performance of the air purifier can be sufficiently exhibited to perform the air cleaning satisfactorily.

The air purifying operation section is not limited to the upper side of the air purifying suction port 6a.
May be provided close to the front side or the rear side.

Next, a second embodiment will be described with reference to FIGS.

FIG. 5 shows the external appearance of the vacuum cleaner, and the inside is not shown. The vacuum cleaner according to this embodiment has the same basic configuration as the vacuum cleaner described in the first embodiment, and thus the description is omitted.
In FIG. 5, the same parts as those in FIG. 1 are denoted by the same reference numerals.

The features of this embodiment will be described. A bumper 121 is provided below the peripheral side surface portion 1c of the main body case 1 over the entire circumferential direction of the main body case 1. For example, as shown in FIG. 7, the bumper 121 has projections 121a formed on the inner peripheral side thereof at intervals in the circumferential direction, and these projections 121a are engaged with holes 122 formed in the wall of the main body case 1. And is attached to the main body case 1. Here, the bumper 121 is a peripheral side portion 1 of the main body case 1.
c is a protruding portion that protrudes outside the main body case from a portion where the air cleaning inlet 6a is provided.

The bumper 121 is provided on the left side surface 1f of the peripheral side surface portion 1c of the main body case 1 near the air cleaning inlet 6a. In this case, in the main body case 1, the bumper 121 is located outside the main body case from the left side surface portion 1f of the peripheral side surface portion 1c provided with the air cleaning suction port 6a. That is, the peripheral side portion 1c of the main body case 1 is located outside the portion provided with the air purifying suction port 6a, and the portion provided with this object and the air purifying suction port 6a when coming into contact with another object. A portion (projecting portion) that forms a gap therebetween, that is, a bumper 121 is provided. The operation unit for operating the air purifier is the main body case 1.
Is provided on the upper surface portion.

According to this configuration, as shown in FIG. 6, when the main body case 1 is installed in such a manner that the portion of the peripheral side surface portion 1c formed with the air cleaning suction port 6a contacts the wall surface P of the room, , The portion located outside the air cleaning inlet 6a near the air cleaning inlet 6a, that is, the bumper 121 abuts against the wall surface P of the room, so that the peripheral side surface portion 1c provided with the air cleaning inlet 6a is provided. There is no gap between the portion and the wall surface P of the room, and the air purification inlet 6a is not directly blocked by the wall surface P of the room. For this reason, the air purifying suction port 6a can satisfactorily suck air through a gap between the peripheral side surface portion 1c where the air purifying suction port 6a is formed and the wall surface P of the room. For this reason, even if the main body case 1 is installed in the direction in which the peripheral side surface portion 1c formed with the air cleaning inlet 6a is in contact with the wall surface P of the room, the air cleaning can be performed. Therefore, the performance of the air purifier can be sufficiently exhibited to perform the air cleaning satisfactorily.

A portion which is located outside the portion where the air cleaning inlet 6a is formed, and which forms a gap between this object and the portion where the air cleaning inlet 6a is formed when it comes into contact with another object. Is not limited to the bumper 121, and may be another appropriate protrusion, or may be formed by protruding the peripheral side surface of the main body case 1. In addition, the present invention is directed to a vacuum cleaner equipped with both a cleaning electric blower and an air cleaning electric blower, but is not limited to this, and is equipped with a single electric blower that is used for both cleaning and air cleaning. May be targeted.
