Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner which is, for example, a backpack type and is driven by a battery, and more particularly to a vacuum cleaner having both a suction function and a blowing function.

[0002]

2. Description of the Related Art Frequent cleaning is necessary on stairs and passageways in premises of stations, pavilions, department stores, etc., because fine dust, cigarette butts, lint, hair, etc. tend to accumulate due to traffic. Become. As a vacuum cleaner used for such cleaning, for example, the vacuum cleaner shown in FIGS. 8 and 9 is known. That is, the cleaner 1 shown in these figures is composed of a cleaner body 2 and a cleaner 3 that is detachably attached thereto. The cleaner main body 2 includes a base frame 4, a body 5, and an upper lid 6. The attachment / detachment metal fitting 7 makes the space between the base frame 4 and the body 5 and the space between the body 5 and the upper lid 6 detachable. Inside the base frame 4, a D having a battery 8 and an impeller 9
A C motor 10 is provided. Here, the impeller 9
The DC motor 10 forms a blower. A blower casing 11 for increasing the pressure of the sucked air is provided at an upper part of the impeller 9, and the intake air pressurized by the blower casing 11 is supplied from a plurality of exhaust windows 12 provided at a lower part of the body 5. It is designed to be discharged outside.

Further, a screen 13 is provided inside the body 5 for collecting fine dust sucked, cigarette butts, lint, hair, and the like. A suction port 14 is provided substantially at the center of the upper lid 6, and the cleaning tool 3 is provided in the suction port 14.
The opening-side end of the bellows tube 15 is detachably mounted. A pipe 17 having a suction tool 16 at the tip is attached to the other end of the bellows tube 15. Further, a backrest cushion 18 and a backpack 19 are provided on a side surface of the body portion 5. In use, as shown in FIG. 10, the worker 20 carries the vacuum cleaner 1 with the backpack 19 on his shoulder and has the pipe 17, so that fine dust, cigarette butts, and threads are drawn from the suction tool 16. Waste, hair and the like can be sucked. At this time, the airflow sucked from the suction tool 16 by the impeller 9 rotated and driven by the DC motor 10 passes through the pipe 17 and the bellows pipe 15 to the suction port 14.
From the body 5. At this time, screen 1
3 collects fine dust, cigarette butts, lint, hair and the like. After the airflow that has passed through the screen 13 is pressurized by the blower casing 11, the airflow is discharged to the outside through a plurality of exhaust windows 12 provided at the lower part of the body 5. Further, as such a backpack type vacuum cleaner, for example, a vacuum cleaner with a built-in battery disclosed in Japanese Utility Model Laid-Open No. 1-156213 is also known.

[0004]

However, in the vacuum cleaner shown in FIGS. 8 to 10, the suction port 14 is substantially at the center of the upper lid 6 and is fixed in the vertical direction. In consideration of this, it is necessary to lengthen the bellows tube 15 inevitably. For this reason, since the bellows tube 15 becomes longer, not only does the bellows tube 15 hinder the handling during cleaning, but also the suction resistance increases, and there is a problem that the suction force is reduced. Further, even the above-described prior art has the same problem as described above since the suction port is provided on one side of the cleaner body. Further, since all of the vacuum cleaners shown in these conventional examples have only a suction function, it is difficult to suck dust and the like in a narrow place where the suction tool 16 does not enter, so that work efficiency is reduced. There is also a defect.

[0005] Incidentally, as described above, by providing a suction function and a blowing function as in a vacuum cleaner disclosed in JP-A-4-58921 and JP-A-61-202516, as described above, the suction tool 16 is provided. Since dust and the like can be expelled by blowing air in a narrow place or the like where the vehicle cannot enter, it is possible to solve the problem that the work efficiency is reduced.
However, the air sucked from the outside into the cleaner body to obtain air supply is a screen 13 for collecting fine dust, cigarette butts, lint, hair and the like shown in FIG.
, The suction resistance increases, which causes a problem that the amount of blown air is reduced.

Further, since the position of the exhaust port is fixed in any of these prior arts, if it is used for cleaning stairs or passages in the premises of stations, pavilion, department stores, etc. Exhaust air from the mouth may be directed to passers-by. In this case, since the exhaust air contains fine dust or the like, or the exhaust air itself is warm air,
It is unsuitable for use in places where pedestrians frequently come and go because it gives discomfort to passers-by. The present invention has been made in view of such circumstances, and has as its object to provide a vacuum cleaner capable of improving the functions of suction and air blowing with a simple configuration.

[0007]

To achieve the above object, a vacuum cleaner according to claim 1 includes a blower (9, 10) for generating an air flow, and a built-in blower (9, 10), and Suction chamber (5A) partitioned by blowers (9, 10)
A main body (2) having a body portion (5) having a blower chamber (5B), a suction port (14a) formed in the suction chamber (5A) side, and a suction port in the suction chamber (5A) side. Mouth (14
a) which is provided so as to surround a) and forms a dust collection chamber, and a screen (1) on the suction chamber (5A) side.
An opening is formed between the blower (9) and the blower (3) and is openable and closable, and an air outlet (27) is formed in the blower chamber (5B). The air taken into the suction chamber (5A) from the suction port (14a) passes through the screen (13), is guided to the blower chamber (5B), is discharged from the discharge blower port (27), and blows air. Sometimes, the air taken into the suction chamber (5A) from the air intake window (28) is guided to the blower chamber (5B) side without passing through the screen (13), and is discharged from the discharge blower port (27). It is characterized by:

The blower (9, 10) comprises, for example, a DC motor (10) and an impeller (9) as shown in FIG. 2, and the impeller (9) is driven by the DC motor (10). By rotation, the suction chamber (5) of the body (5) is rotated.
The air flow is generated between A) and the blower chamber (5B). Here, when the AC drive is performed, the DC motor (10) may be an AC motor. Vacuum cleaner body (2) by air flow from blowers (9, 10)
Is taken in from the suction port (14a), the suction port (14a) is provided on the upstream side of the airflow. On the other hand, since the air discharged from the inside of the cleaner body (2) to the outside is discharged from the discharge air port (27), the discharge air port (27) is provided downstream of the air flow. Here, the exhaust port (27) is an exhaust port when the suction function is used, and is an air port when the blow function is used. Therefore, by attaching the cleaning tool (3) to either the suction port (14a) or the exhaust port (27), either the suction function or the blowing function can be used. The air intake window (28) is closed when the suction function is used, and is opened only when the air blowing function is used to take in external air. Screen (1
Reference numeral 3) denotes a so-called filter for collecting fine dust, cigarette butts, lint, hair, and the like sucked by the cleaning tool (3) when the suction function is used. Therefore, when collecting finer dust and the like, a filter with a finer eye is used.

According to such a configuration, when the cleaning tool (3) is attached to the suction port (14a) to use the suction function,
Fine dust, cigarette butts, lint, hair, and the like taken in through the suction port (14a) are collected by the screen (13) inside the suction chamber (5A), and the exhaust air is sent to the air blowing chamber (5B). The air is discharged to the outside from the discharge air port (27) on the side.
At this time, by opening and closing the openable air intake window (28) provided outside the dust collection chamber formed by the screen (13) on the suction chamber (5A) side, the suction chamber (5A) is closed.
The degree of vacuum of A) can be maintained, and the function of sucking air from the suction port (14a) is not reduced.

On the other hand, when the cleaning tool (3) is attached to the discharge air port (27) to use the air blowing function, the cleaning tool (3) is provided outside the dust collecting chamber formed by the screen (13) on the suction chamber (5A) side. The opened and closed air intake window (28) is opened. Thereby, the air taken in from the air intake window (28) passes through the exhaust port (27) and is sent out from the tip of the cleaning tool (3). At this time, since the air taken into the suction chamber (5A) does not pass through the screen (13), there is no generation of suction resistance due to the conventional screen (13), and the blowing performance can be improved. As a result, finer filters can be used for the screen (13). At this time, the suction port (14
Air is also taken in from a), but since the suction resistance by the screen (13) is high, the amount of air taken in from the suction port (14a) is smaller than the amount of air taken in from each air intake window (28). It becomes a trace amount. In addition, the suction port (14
a) may be closed with a cap or the like so that air is taken in only from each air intake window (28).
In addition, when the cleaning tool (3) is attached to the suction port (14a) or the exhaust port (27) at the open end, it is not limited to the case where the cleaning tool (3) is fixed by the clamp (15b) as shown in FIG. In this case, the bellows tube (15a) can be easily attached and detached.

[0011] In the vacuum cleaner according to the second aspect, the body part (5)
Is open at one end, the opening is closed by a removable lid (6), and the suction port (14a) is provided at a position offset from the center of the lid (6). . According to such a configuration, the suction port (1
4a) is deviated from the center of the upper lid (6), so that, for example, when the vacuum cleaner is a backpack type, the suction port (14a) can be moved to a position closer to the arm side, so that the bellows tube 15a is moved. It can be even shorter.

According to a third aspect of the present invention, in the vacuum cleaner, the suction port (14)
a) is characterized in that it is cylindrical and its open end side is inclined with respect to the axis of the body part (5). According to such a configuration, by attaching the upper lid (6) to the body part (5) in an arbitrary mounting direction, the suction port (1) is provided.
The direction of 4a) can be changed. Thus, for example, when the vacuum cleaner is a backpack type, the suction port (14a) can be brought closer to the right or left arm side, and for example, as shown in FIG. 6, the suction port (14a) is brought closer to the arm side. The bellows tube (15a) can be shortened by the same amount, and the conventional bellows tube (15) becomes longer, so that not only does the bellows tube (15) become a hindrance at the time of handling during cleaning,
The problem that the suction resistance is increased and the suction force is reduced can be solved.

[0013] A vacuum cleaner according to a fourth aspect is characterized in that the air intake window (28) is opened and closed by a slide shutter (29) that is movable in the circumferential direction of the body (5). Here, the number of the air intake windows (28) may be one or two or more. In any case, in order to increase the suction efficiency, the total opening area of the air intake windows (28) is increased. Is preferred. In addition, the air intake window (2
8) are preferably arranged along the moving direction of the slide shutter (29) so that the slide shutter (29) can be easily opened and closed. According to such a configuration, when the suction tool (3) is attached to the suction port (14a) and the suction function is used, the air intake window (28) is closed by the slide shutter (29). Exhaust of the exhaust gas from (28) can be prevented. On the other hand, when the cleaning tool (3) is attached to the air outlet (27) to use the air blowing function, the slide shutter (29) is used.
, The air intake window (28) can be easily opened.

According to a fifth aspect of the present invention, there is provided a vacuum cleaner, comprising:
7) is characterized in that it is provided movably in the circumferential direction of the body portion (5). According to such a configuration,
When the suction function is used, air inside the cleaner body (5) is exhausted from the exhaust port (27). For example, as shown in FIG. 6, suction cleaning is performed in the upper or lower direction along the left side of the stairs. When carrying out, since the exhaust air outlet (27) is directed to the left end direction of the stairs, the exhaust air from the exhaust air outlet (27) is not directed to the passerby side, so discomfort is given to the passerby. I will not give it.

According to a sixth aspect of the present invention, there is provided a vacuum cleaner, comprising:
7) is characterized in that it is attached to a slide plate (28a) movably provided in the circumferential direction of the body portion (5). According to such a configuration, the slide plate (28
Since the position of the discharge air port (27) is changed by the movement of a), even during the cleaning operation, it is possible to prevent the exhaust air from the discharge air port (27) from being directed to the pedestrian,
The cleaning operation can be performed efficiently without interrupting the cleaning.

[0016] The vacuum cleaner according to claim 7 is a blower (9,
10) The battery (8) built in the body (5)
It is driven by electric power from
Here, the cleaner body (5) may be provided with a charging connector (23) and a battery capacity display section (24) for checking the capacity thereof, as shown in FIG. 2, for example. The connector (23) not only facilitates charging of the battery (8), but also provides a battery capacity display (2).
4) makes it easy to check the charging time. According to such a configuration, the blowers (9, 10) are connected to the battery (8).
6 and 7, for example, as shown in FIGS. 6 and 7, the vacuum cleaner can be of a backpack type, so that people can travel on stairs and passages in the premises of stations, pavilion, department stores, and the like. Finer dust, cigarette butts, etc.
This can be suitable for frequent cleaning in a place where lint, hair, and the like easily accumulate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the drawings. In the drawings described below, FIG.
10 are denoted by the same reference numerals. FIG. 1 is a perspective view showing an embodiment in which the vacuum cleaner of the present invention is applied to a backpack type, FIG. 2 is a cross-sectional view taken along line II-II of the vacuum cleaner of FIG. 1, and FIG. FIG. 4 is a plan view showing an upper cover attached to the body, FIG. 4 is a partial cross-sectional view showing the state of attachment of the upper cover to the body shown in FIG. 2, and FIG. 5 is a side view showing a detachable metal fitting for making the upper cover detachable in FIG. FIG. 1 and 2
As shown in FIG. 1, the cleaner 1 includes a cleaner body 2 and a cleaner 3 that is detachably attached thereto. The cleaner main body 2 includes a base frame 4, a cylindrical body 5, and an upper lid 6. Detachable metal fittings 7, 7A are provided between the base frame 4 and the body 5 and between the body 5 and the upper lid 6.
Are detachable. Here, the configuration of the attachment / detachment metal fitting 7A to which the upper lid 6 is attached is different from the conventional one, but the details will be described later.

A battery support frame 21 and a motor support frame 22 are provided inside the base frame 4.
In each case, a battery 8 and a DC motor 10 having an impeller 9 are supported. Here, impeller 9 and D
A blower is constituted by the C motor 10. And
By driving the blower, an airflow is generated inside the cleaner body 2. Also, base frame 4
The charging connector 2 for charging the battery 8
3 and a battery capacity display unit 24 for checking the capacity. Thus, the battery 8 can be easily charged by the charging connector 23, and the charging time can be easily confirmed by the battery capacity display unit 24. Further, a cord 25 and a switch 26 are connected between the battery 8 and the DC motor 10, and when the switch 26 is turned on, the DC motor 10 is driven. Since the switch 26 is mounted at a position where it can be reached when the cleaner 1 is carried on its back, the drive of the DC motor 10 can be turned on / off even during cleaning. I have.

An upper part of the impeller 9 is provided with a suction chamber 5A, and a lower part thereof is provided with a blower chamber 5B. A blower casing 11 for increasing the pressure of the sucked air is provided on the upper side of the impeller 9, and the air boosted by the blower casing 11 is supplied to a plurality of exhaust air provided at a lower portion of the body 5. It is sent to the window 12 side. Here, these exhaust windows 12 are provided inside a slide plate 28 a having an exhaust port 27 that is slidably mounted in the circumferential direction of the body 5, and each exhaust window 12 The air that has passed through the window 12 travels inside the slide plate 28a and is guided to the exhaust port 27 side,
The air is discharged from the air outlet 27 to the outside.
The exhaust port 27 is an exhaust port when the suction function is used, and is an air port when the blow function is used. Then, by sliding the slide plate 28a in the circumferential direction of the body portion 5, the direction of the discharge air port 27 can be arbitrarily changed. Therefore, when the suction function is used, the direction of exhaust by suction can be arbitrarily changed. When using the air blowing function,
By moving the discharge air port 27 to the side of the hand, it is possible to use a cleaning tool 3 that is short enough to be in the way when it is handled during cleaning.

The suction chamber 5A inside the body 5 has
A screen 13 supported by a screen support frame 13a is provided. The screen 13 is provided so as to surround a suction port 14a described later, and forms a dust collection chamber. Here, the screen 13 is a so-called filter that collects fine dust, cigarette butts, lint, hair, and the like sucked by the cleaning tool 3.
Therefore, in order to further separate finer dust and the like, it is preferable to use a filter with finer eyes. Further, a plurality of air intake windows 28 are provided along the circumferential direction at a position in the middle of the body portion 5 outside the dust collection chamber formed by the screen 13. A slide shutter 29 having a handle 29a and a plurality of communication holes 29b is slidably mounted on the body 5 at a position surrounding each air intake window 28 in the body 5 in a circumferential direction. The slide shutter 29 is used to open each air intake window 28 when using the air blowing function and to slide when taking in air. The slide of the slide shutter 29 causes each communication hole 29b and each air intake window 28 to slide. Is made to match, so that each air intake window 28 is opened. Here, the number of the air intake windows 28 may be one or two or more, but in any case, it is preferable to increase the total opening area of the air intake windows 28 in order to increase the suction efficiency. .

The air taken in from each of the air intake windows 28 is sent to the exhaust port 27 side without passing through the screen 13, so that there is no suction resistance generated when the air passes through the screen 13 as in the conventional case. For this reason, a reduction in the amount of blown air is suppressed. Also, the air intake window 28
Since the air taken in from the air does not pass through the screen 13, the screen 13 can be used as a filter with finer eyes, and finer dust can be absorbed. On the other hand, when the suction function is used, each air intake window 28 is closed by sliding each communication hole 29b and each air intake window 28 by sliding the slide shutter 29, so that the degree of vacuum of the suction chamber 5A is reduced. , And the air suction force does not decrease. Also,
A packing 30 is interposed between the upper part of the body part 5 and the upper lid 6 to seal the inside of the body part 5. Thereby, particularly when the suction function is used, there is no air leakage between the upper part of the body part 5 and the upper lid 6, so that a decrease in the suction capacity is suppressed.

As shown in FIGS. 3 to 5, a ring-shaped concave groove 31 is provided on the outer peripheral edge of the upper lid 6. A C-shaped hook fitting 32 fits into the concave groove 31. The hook fitting 32 is provided integrally with the operation piece 33, and the operation piece 33 is turned to the receiving seat 34 via a fulcrum pin 35 of a receiving seat 34 attached to the upper part of the body 5. It is movably supported. A cylindrical suction port 14a is provided at the center of the upper lid 6.
Is attached with its opening directed in the radial direction of the upper lid 6. In addition, the suction port 14a is not limited to a straight columnar shape as in the illustrated example, but may be a substantially L-shaped or curved shape. Then, by fitting the hook fitting 32 into an arbitrary portion of the ring-shaped concave groove 31, the upper lid 6 is attached and fixed to the body 5. Thereby, the torso part 5
The mounting direction of the upper cover 6 with respect to the
The direction of the cylindrical suction port 14a can be directed toward the arm of the worker 20. Therefore, when the suction function is used, it is possible to use the cleaning tool 3 which is short enough to be out of the way during the cleaning operation.

Here, the cleaning tool 3 is provided with a bellows tube 15a and a pipe 17, as shown in FIG. A suction device 16 used at the time of suction or a blower 16a used at the time of blowing is detachably attached to a distal end portion of the pipe 17. In addition, the bellows tube 15a
The open-side end portion is detachably attached to the suction port 14a or the discharge air port 27 by using a clamp 15b. When the open end of the bellows tube 15a is attached to the suction port 14a or the exhaust port 27, it is not limited to the clamp 15b of this example, but may be a one-touch fitting type. 15a
Can be easily attached and detached. Furthermore, on the side of the body part 5,
As shown in FIG. 1, a backrest cushion 18 and a backpack 19 are provided.

The operation of the vacuum cleaner 1 having such a configuration is as follows. That is, FIG. 6 is a perspective view illustrating a cleaning mode using the suction function, and FIG. 7 is a perspective view illustrating a cleaning mode using the blowing function. First, when the suction function shown in FIG. 6 is used, the open side end of the bellows tube 15a is connected to the suction port 14a with a clamp 15b as shown in the cleaning tool 3 shown by a solid line in FIG.
Attach using At this time, as described with reference to FIGS. 3 to 5, the hook fitting 32 is loosened by operating the operation piece 33, and the direction of the inclined suction port 14 a of the upper lid 6 is changed by the worker 2.
The mounting position of the upper lid 6 is determined so that the upper lid 6 faces the 0-arm side.
After the mounting position of the upper cover 6 is determined, the operation piece 33 is returned to the original position, so that the hook fitting 32 fits into an arbitrary portion of the concave groove 31 of the upper cover 6, so that the mounting position of the upper cover 6 can be easily changed. I can do it. Next, after the worker 20 carries the cleaner 1 with the backing 19 on the shoulder, the switch 26 is turned on, so that the DC motor 10 is driven. When the impeller 9 rotates by the drive of the DC motor 10, the inside of the body 5 is made to have a negative pressure, so that the suction by the suction tool 16 is performed. Thus, when fine dust, cigarette butts, lint, hair, and the like are sucked by the suction tool 16, they pass through the pipe 17 and the bellows pipe 15a and pass through the suction port 14a.
From the main body 5 to the suction chamber 5A. Suction chamber 5A
The fine dust, cigarette butts, lint, hair and the like guided by the screen are received by the screen 13.

After the air flow passing through the screen 13 is pressurized by the blower casing 11, it passes through the respective exhaust windows 12 on the side of the blow chamber 5 B of the body 5, passes through the inside of the slide plate 28 a, and passes through the exhaust port 27. Is sent to the outside. At this time, if the direction of the exhaust port 27 is directed toward the passerby, the slide plate 28a can be slid in the circumferential direction of the body 5 to change the direction of the exhaust port 27, so The cleaning operation can be performed without giving a pedestrian an unpleasant feeling due to fine dust and the like contained in the exhaust air and the warm air of the exhaust air itself. Next, as shown in FIG. 7, when the air blowing function is used, the open side end of the bellows tube 15 a is connected to the clamp 15 b to the exhaust air port 27 as in the cleaning tool 3 shown by the dashed line in FIG. 2. Install using. At this time, slide plate 2
8a can be changed in the circumferential direction of the body portion 5 to change the position of the exhaust port 27.
Is moved to the dominant side. At this time,
Hold the slide shutter 29 with the handle 29a and the body 5
To make the plurality of communication holes 29b of the slide shutter 29 and the air intake windows 28 of the body 5 coincide with each other, and each air intake window 28 is opened. Further, a blower 16a is attached to the tip of the pipe 17 of the cleaning tool 3 instead of the suction tool 16.

After the above preparations are completed, the worker 20 carries the vacuum cleaner 1 with the backpack 19 on his shoulder, turns on the switch 26, and drives the DC motor 10. When the impeller 9 rotates by the driving of the DC motor 10, the inside of the body 5 becomes negative pressure, and the air intake windows 28 of the body 5
Air is taken into the suction chamber 5A from the inside. At this time, the air from each air intake window 28 is taken into the suction chamber 5A without passing through the screen 13, so that it does not receive the suction resistance by the screen 13, so that the air is taken in efficiently. At this time, air tends to be taken in from the suction port 14a. However, since the suction resistance by the screen 13 is high, the amount of air taken in from the suction port 14a is smaller than the amount of air taken in from each air intake window 28. And it is very small. In addition, the suction port 14a may be closed with a cap or the like, and air may be taken in only from each air intake window 28. In this way, the air taken into the suction chamber 5A from each air intake window 28 is guided to the side of the blower casing 11 without passing through the screen 13, and after being pressurized by the blower casing 11,
After passing through the discharge air outlet 27, the air is sent from the air blower 16 a through the bellows pipe 15 a and the pipe 17 of the cleaning tool 3. Therefore, in a narrow place where the suction tool 16 cannot enter, dust and the like can be expelled by blowing air, so that efficient cleaning work can be performed.

As described above, in the present embodiment, when the cleaning tool (3) is attached to the suction port (14a) and the suction function is used, fine dust taken in through the suction port (14a) is removed. Remove cigarette butts, lint, hair, etc. into the suction chamber (5
A) Dust is collected by the internal screen (13), and the exhaust air is exhausted to the outside from the exhaust air port (27) on the side of the air blowing chamber (5B). On the other hand, the cleaning tool (3) is
7) When the air blower is used by attaching it to the suction chamber (5A) from the air intake window (28), the air taken into the suction chamber (5A) from the tip of the cleaning tool (3) without passing through the screen (13). Since the air is sent out, the functions of suction and air blowing can be improved with a simple configuration. Also,
The upper lid (6) is mounted in the body part (5) in any mounting direction and the direction of the suction port (14a) is changed, so that the suction port (14a) is brought closer to the right or left arm side. For example, as shown in FIG.
The bellows tube (15a) can be shortened by the amount of a) approaching the arm side. As a result, the bellows tube (15) as in the related art becomes longer, which not only obstructs the bellows tube (15) during the cleaning operation, but also increases the suction resistance and reduces the suction force. The problem that the data is lost can be solved. Furthermore, when the suction tool (3) is attached to the suction port (14a) to use the suction function, the air intake window (2) is moved by the slide shutter (29).
Since 8) is closed, leakage of exhaust gas from the air intake window (28) can be prevented. On the other hand, when the cleaning tool (3) is attached to the air outlet (27) to use the air blowing function, the air intake window (28) can be easily opened by moving the slide shutter (29). .

When the suction function is used, the air inside the cleaner body (5) is exhausted from the exhaust port (27). For example, as shown in FIG. Or, when performing suction cleaning in the lower direction,
Since 7) is directed toward the left end of the stairs, the exhaust air from the exhaust vent (27) is not directed toward the passerby, so that the passenger does not feel uncomfortable. Furthermore, the movement of the slide plate (28a) causes the discharge air outlet (2
Since the position of 7) is changed, even during the cleaning operation, the exhaust air from the exhaust port (27) can be prevented from being directed to passers-by, and the cleaning operation can be performed without interrupting the cleaning. It can be performed efficiently.

The dust is collected by the screen (13) inside the suction chamber (5A), and the exhaust air is discharged to the air outlet (27) on the side of the air blower chamber (5B).
Is discharged to the outside. On the other hand, when the cleaning tool (3) is attached to the air outlet (27) and the air blowing function is used, the air taken in from the air inlet window (28) is removed from the screen (1).
It is taken in without passing through 3), passes through the discharge air outlet (27), and is sent out from the tip of the cleaning tool (3), so that the functions of suction and blowing can be improved with a simple configuration. .

[0031] According to the vacuum cleaner of the second aspect,
Since the suction port (14a) is offset from the center of the upper lid (6), for example, when the vacuum cleaner is a backpack type, the suction port (14a) is not provided.
Since a) can be moved to a position closer to the arm side, the bellows tube 15a can be further shortened.
Furthermore, according to the vacuum cleaner of claim 3, the top lid (6)
By attaching to the body part (5) in any mounting direction, the direction of the suction port (14a) can be changed,
For example, when the vacuum cleaner is a backpack type, the suction port (14a) can be brought closer to the right or left arm side, so that, for example, as shown in FIG. The bellows tube (15a) can be shortened.
As a result, the bellows tube (15) as in the related art becomes longer, which not only obstructs the bellows tube (15) during the cleaning operation, but also increases the suction resistance and reduces the suction force. The problem that the data is lost can be solved.

Furthermore, according to the vacuum cleaner of the fourth aspect, when the cleaning tool (3) is attached to the suction port (14a) and the suction function is used, the air intake window (29) is provided by the slide shutter (29). Since (28) is closed, leakage of exhaust gas from the air intake window (28) can be prevented. On the other hand, when the cleaning tool (3) is attached to the air outlet (27) to use the air blowing function, the slide shutter (2) is used.
By moving 9), the air intake window (28) can be easily opened. According to the fifth aspect of the present invention, when the suction function is used, the air inside the cleaner body (5) is exhausted from the exhaust port (27). For example, as shown in FIG. When performing suction cleaning in the upper or lower direction along the left side of the stairs, the discharge air vent (27)
To the left end of the stairs,
Since the exhaust gas from 7) is not directed to the passerby side, the passenger does not feel uncomfortable.

Further, according to the vacuum cleaner of the sixth aspect, the movement of the slide plate (28a) causes the discharge air outlet (2).
Since the position of 7) can be changed, even during cleaning work,
It is possible to prevent the exhaust air from the exhaust outlet (27) from being directed to passers-by, so that the cleaning operation can be performed efficiently without interrupting the cleaning. Furthermore, according to the vacuum cleaner of claim 7, by driving the blowers (9, 10) with the electric power from the battery (8), for example, FIG.
And as shown in FIG. 7, the vacuum cleaner can be a backpack type, and fine dust, cigarette butts due to traffic of people, etc. on stairs and passages in the premises of stations, pavilions, department stores, etc.
This can be suitable for frequent cleaning in a place where lint, hair, and the like easily accumulate.
