Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner having both characteristics of a so-called canister type and a so-called upright type.

A so-called canister-type vacuum cleaner (hereinafter simply referred to as “vacuum cleaner”) usually has a suction pipe with one end having a suction port for sucking dust and a suction pipe connected to the other end. Move the mouth on the floor to perform cleaning work. A vacuum cleaner main body is connected to the tip of the suction hose.
The main body of the vacuum cleaner including the suction motor, the dust collection chamber, and the power source is moved by being pulled by the suction hose as the suction port moves on the floor surface. The vacuum cleaner body is usually equipped with wheels so that it can move on the floor surface with a light force.

A so-called upright type, stand type or stick type vacuum cleaner is used in a state in which the suction port body and the vacuum cleaner body are integrated. And preferably, it can be stored in a state of being self-supporting on the floor surface or being hung on a wall surface or the like.
Usually, the vacuum cleaner main body is long in the direction perpendicular to the floor surface, the suction port body is connected to the lower end side of the vacuum cleaner main body, and the handle is connected to the upper end side. The user holds the handle in one hand and moves the lower suction port on the floor to perform the cleaning work.

In some cases, the angle formed between the suction port body and the cleaner body is variable so that the suction port body moves along the floor surface during cleaning work. Further, usually, a roller is disposed on the lower surface side where the suction port body is in contact with the floor surface so that the suction port body can move smoothly on the floor surface.
There has been proposed a vacuum cleaner capable of properly using a canister type usage pattern and an upright type usage pattern (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 2003-265281

The advantage of the canister type vacuum cleaner is that the main body of the vacuum cleaner and the suction port body are separated by a flexible suction hose, so that the suction port body can be easily moved. For example, it is easy to handle the suction port even in a cleaning operation in a narrow place such as a toilet in a general household. In addition, it is easy to clean windows and wall surfaces at high places.
On the other hand, because it has a flexible suction hose, the behavior of the cleaner body that is moved by being pulled by the suction hose is not fixed, and it can collide with surrounding walls and objects, or it can not proceed due to being caught by an obstacle. There are things to do. Lifting the body to move it as intended by the user puts a heavy burden on the handle. Moreover, the position of a suction inlet and a suction pipe is not fixed with respect to a cleaner body at the time of storage.

On the other hand, the upright type vacuum cleaner easily moves the main body of the vacuum cleaner as intended by the user. In addition, the positional relationship between the suction port body and the cleaner body is fixed and easy to store.
On the other hand, in order to move the suction port on the floor surface, the main body of the vacuum cleaner must be moved together, so that more force is required during the cleaning operation than the canister type vacuum cleaner. Also, it is difficult to clean narrow places or high places such as windows and wall surfaces.
The vacuum cleaner of Patent Document 1 is configured so that both types can be used properly according to the usage situation. However, when taking the upright type of usage, the load of the cleaner body is applied to the suction port.
The present invention has been made in consideration of the above circumstances, and provides a vacuum cleaner that can easily move the vacuum cleaner body and the suction port body as the user intends. .

  The present invention has a suction nozzle portion having a suction port body on one end side, and having a nozzle portion handle on the other end side that an operator can hold with one hand when moving the suction port body on the floor surface; A support unit that detachably supports the suction nozzle unit, a dust collection chamber that contains dust, a suction motor that guides dust from the suction port body to the dust collection chamber by an air flow, a power supply unit that drives the suction motor, and a floor Provided is a vacuum cleaner comprising a vacuum cleaner body including a main body handle that the operator can hold with the other hand when moving on a surface, and a suction hose connecting the suction port body and the dust collecting chamber To do.

The vacuum cleaner according to the present invention includes a suction nozzle portion having a suction port body on one end side and a nozzle portion handle on the other end side, a vacuum cleaner body including a main body handle, the suction port body, and the dust collecting chamber. The user who is the operator holds the nozzle handle with one hand and moves the suction port body as intended, and holds the main body handle with the other hand to clean the vacuum cleaner. The main body can be moved as intended.
Further, the vacuum cleaner body includes a support part that detachably supports the suction nozzle part, so that if the suction nozzle part is attached to the vacuum cleaner body, the positional relationship between the suction port and the vacuum cleaner body is determined and stored. Easy to do.

Hereinafter, the present invention will be described in more detail with reference to the drawings. In addition, the following description is an illustration in all the points, Comprising: It should not be interpreted as limiting this invention.
(Embodiment 1)
[Overall description of the vacuum cleaner]
The vacuum cleaner according to the embodiment of the present invention is roughly classified into a suction nozzle portion having a suction port body, a vacuum cleaner body having a dust collection chamber and a suction motor, and a suction connecting the vacuum cleaner body and the suction nozzle portion. It consists of a hose.
1 and 2 are side views of a vacuum cleaner according to an embodiment of the present invention. FIG. 1 shows a state where the suction nozzle portion and the cleaner body are separated. FIG. 2 shows a state in which the suction nozzle portion is supported and integrated with the support portion of the cleaner body.
FIG. 3 is a perspective view of the electric vacuum cleaner according to this embodiment as viewed obliquely from the rear, and FIG. 4 is a perspective view of the vacuum cleaner as viewed from obliquely upward at the front.

As shown in FIGS. 1 to 4, the electric vacuum cleaner 1 includes a vacuum cleaner body 100 in which a cyclone type dust collection chamber 500 is detachably incorporated, and a suction nozzle unit 300.
The suction nozzle unit 300 is connected to the extension pipe 302, the suction port 303 connected to the tip of the extension pipe 302, the nozzle unit handle 304, the operation unit 305 attached to the nozzle unit handle 304, and one end of the suction hose 301. The connection part 306 is provided. The operation unit 305 includes an operation lever that operates and stops a suction motor 106, which will be described later, and an operation button that sets the strength of the suction motor.

The other end of the suction hose 301 is detachably connected to the front of the cleaner body 100, and the user holds the suction port body 303 at the tip of the extension pipe 302 while holding the nozzle handle 304 with either left or right hand. It can be moved while contacting F. The suction port 303 has a free roller on the lower surface in contact with the floor surface F. The rotation of the roller allows the user to move the suction port 303 to the intended position and the intended direction with a light force.
Further, the extension pipe 302 has hooks 307a and 307b at two locations on the upper and lower sides, respectively. By hooking these hooks 307a and 307b on support portions 150a and 150b (to be described later) of the cleaner body 100, the hook body 307a and 307b can be integrated with the cleaner body 100 (see FIG. 2).

The vacuum cleaner main body 100 has a carriage 101 at the bottom. The carriage 101 includes four universal wheels 117 on the front, rear, left and right of the lower surface. Further, support parts 150 a and 150 b corresponding to the upper and lower hooks 307 a and 307 b of the suction nozzle part 300 are attached to the upper surface of the carriage 101.
The vacuum cleaner main body 100 also includes a dust collection chamber 500, a filter 551, a suction motor 106, a power supply unit, and a main body handle 151, which rotate together around the horizontal axis on the carriage 101 before and after. The inclination angle of the direction can be changed. The inclination angles of the support portions 150a and 150b are also changed according to the change in the inclination angle (see FIG. 6).
The hooks 307a and 307b have long claws so that the hooks are maintained even if the hooks on the support portions 150a and 150b slightly change in the depth direction, that is, the vertical direction. Therefore, when the inclination of the housing 102 changes in a state where the suction nozzle unit 300 is hung on the support units 150a and 150b, the inclination of the suction nozzle unit 300 changes accordingly. At this time, the suction port body 303 is kept in contact with the floor surface F.

Since the vacuum cleaner main body 100 includes the main body handle 151, the user holds the main body handle 151 with the other hand while holding the nozzle handle 304 with one of the left and right hands, and holds the cleaner main body 100 on the floor surface F. It is possible to move with. The main body handle 151 can be expanded and contracted in the vertical direction. Further, the tilt angle in the front-rear direction can be adjusted integrally with the housing 102. Therefore, the main body handle 151 can be adjusted so that the grip portion has a height and a posture that are easy for the user to use.
That is, most of the vacuum cleaner main body 100 including the main body handle 151 can be tilted like a carry back. However, the carriage 101 having the free wheel 117 is kept horizontal on the floor surface F.

  The suction nozzle unit 300 and the vacuum cleaner main body 100 are connected by the suction hose 301. Therefore, even if the user moves while holding only the nozzle unit handle 304 by hand, the vacuum cleaner main body 100 follows the operation. To do. However, one feature of the electric vacuum cleaner 1 is that the user can move the vacuum cleaner main body 100 to an intended place with a light force by gripping the main body handle 151 during a cleaning operation. For example, when cleaning a narrow place such as a toilet, the suction handle 303 can be moved freely by holding the nozzle handle 304 with one hand, and the main body handle 151 can be held with the other hand to freely move the vacuum cleaner main body 100. The cleaning work can be easily performed by moving to. Further, since the cleaner main body 100 is naturally positioned in front of or on the side of the user by gripping the main body handle 151, the cleaner main body 100 unintentionally collides with the wall surface or furniture, and the wall surface or furniture is soiled or damaged. It is expected that this can be prevented.

FIG. 5 is a central cross-sectional view showing a cross section perpendicular to the floor surface F of the cleaner body 100 according to this embodiment.
As shown in FIG. 5, the vacuum cleaner main body 100 has a tubular suction port 310 to which the other end of the suction hose 301 is detachably connected. Here, the front of the vacuum cleaner main body 100 is a direction toward the left side in FIG. 5, and the rear is the opposite, that is, a direction toward the right side in FIG. The suction port 310 can rotate around an axis perpendicular to the cross section, and can change the angle following the suction hose 301 connected thereto. One end of the extension hose 311 is connected to the side opposite to the side to which the suction hose 301 is connected in the suction port 310. The other end of the extension hose 311 is connected to a suction duct 312 disposed inside the cleaner body 100. The tip of the suction duct 312 communicates with a substantially cylindrical and transparent dust cup 501 that constitutes the outer peripheral side wall of the dust collection chamber 500. An inflow port 503 is provided above the cylindrical side wall of the dust cup 501.

  When the suction motor 106 is activated to generate an air flow, the dust flowing into the cleaner main body 100 through the suction hose 301 together with air flows from the inlet 503 to the dust cup 501 through the suction port 310, the extension hose 311, and the suction duct 312. Led. The air introduced into the dust cup becomes a swirl flow along the outer wall of the substantially cylindrical dust cup 501, and the dust is separated from the air by centrifugal force. The centrifuged dust collects below the dust cup 501. On the other hand, the air from which the dust has been separated is discharged above the center of the dust cup 501.

An inner cylinder 533 is coaxially arranged at the center of the substantially cylindrical dust cup 501, and the side wall of the inner cylinder 533 has a mesh shape so that air can pass through. At the upper end of the inner cylinder 533, an outlet 533b for discharging air is provided. A dust partition 535 is disposed between the central portion and the lower end portion of the inner cylinder 533 to prevent dust accumulated at the lower end portion of the dust cup 501 from rising and entering the inner cylinder 533.
A filter 551 is disposed above the outlet 533b. The air discharged from the outlet 533b passes through the filter 551, and fine dust is removed. The air that has passed through the filter 551 descends through the upper exhaust duct 313 and the lower exhaust duct 314 on the rear side of the cleaner body 100 and is guided to the suction motor 106 disposed below the dust collection chamber 500.
The air guided to the suction motor 106 is then discharged out of the cleaner body 100 through the exhaust port 133.

The user may visually check the dust collection status of the dust collection chamber 500, and appropriately remove the upper discharge duct 313 and the dust collection chamber 500 from the cleaner body 100 and discard the dust collected in the dust collection chamber 500. it can.
Since the dust collection chamber 500 is located at the upper part of the cleaner body 100, the user does not need to bend down when discarding dust. The physical burden is alleviated compared to a mode in which a dust collection chamber is near the floor.
As shown in FIGS. 1 to 5, the size of the vacuum cleaner main body 100 excluding the main body handle has a maximum dimension in the height direction that is larger than any of the maximum dimensions in the front-rear direction and the left-right direction, and is vertically long. . Since heavy objects such as the suction motor 106 and the cord reel 108 around which the AC power cord 160 is wound are disposed at the bottom of the cleaner body 100, the center of gravity is low and the running is stable.
The dust collection chamber 500, the AC outlet plug 131, and the brake button 132, which are frequently operated by the user, are arranged on the upper part of the cleaner body 100, and the user does not need to take a posture in which the body is bent deeply.

  A cord reel 108 and a brake mechanism biased by a spring are built in the front of the suction motor 106 and at the center bottom of the cleaner body 100. An AC power cord 160 is wound around the cord reel 108. The AC outlet plug 131 attached to the end of the AC power cord 160 is exposed at the upper center of the cleaner body 100 and between the filter 551 and the main body handle 151. Also, a brake button 132 for releasing the brake of the cord reel 108 is disposed near the AC outlet plug 131. When the brake button 132 is operated, the brake is released, the cord reel 108 is rotated by the spring force, and the AC power cord 160 is wound up.

A printed wiring board 120 that controls the rotation of the suction motor 106 is disposed below the cord reel 108. The AC power cord 160, the cord reel 108, and the printed wiring board 120, to which the AC outlet plug 131 is attached, constitute a power supply unit according to the present invention.
Since the AC outlet plug 131 is exposed at the top of the cleaner body 100, the user does not need to bend down when pulling out the AC power cord 160 with the AC outlet plug 131. The physical burden is alleviated as compared with a mode in which the AC outlet plug 131 is exposed near the floor.

The vacuum cleaner main body 100 includes a substantially disc-shaped carriage 101 that forms a lower portion thereof, and a housing 102 that houses a suction duct 312, a suction motor 106, and a power supply unit. The housing 102 also supports the dust collection chamber 500.
Further, a pair of upper and lower support portions 150 a and 150 b are disposed at the front end portion of the upper surface of the carriage 101. The lower support portion 150b is shifted in the front-rear direction of the carriage 101 and is urged rearward by a spring. The information support portion 150a is attached to a support shaft 153a and support arms 153L and 153R spanned between a pair of left and right support columns 152L and 152R standing at the front end of the carriage 101 so as to be rotatable about the shaft. Yes.

Furthermore, a pair of left and right handle columns 154L and 154R that support the main body handle 151 are disposed in front of the housing and behind the columns 152L and 152R. A handle support shaft 155 is stretched over the upper ends of the handle columns 154L and 154R. A main body handle 151 is attached above and below the center of the handle support shaft 155 so as to extend and contract. A grip portion 151 a is provided at the upper end of the main body handle 151. A suction port 310 is rotatably mounted between the handle columns 154L and 154R.
The housing 102, the handle columns 154L and 154R, and the main body handle 151 are integrally rotatable about an axis perpendicular to the paper surface of FIG. By rotating, the main body handle 151 can be positioned perpendicular to the floor surface F, or can be positioned in a tilted state.

FIG. 6 is a side view showing a state in which the grip portion of the main body handle 151 is inclined rearward with respect to the vacuum cleaner 1 according to this embodiment. Curved base materials 156L and 156R formed in a pair of left and right arcs are disposed at the bottom of the housing 102. Each of the curved base materials 156L and 156R slides with respect to the carriage 101 while fitting with a pin fixed to the carriage 101. As a result, the casing 102 and the main body handle 151 can be integrated to change the tilt angle in the front-rear direction with respect to the floor surface F.
As shown in FIG. 6, when the grip portion of the main body handle 151 is tilted backward, the bottom portion of the housing 102 protrudes forward. The lower support part 150b is pushed by the protruding housing 102 and shifts forward. Therefore, the suction nozzle part 300 supported by the support parts 150a and 150b changes the inclination angle while the suction port body 303 is kept in contact with the floor surface F.

As described above, the user holds the nozzle handle 304 with one hand and moves the suction port body 303, holds the main body handle 151 with the other hand, and moves the vacuum cleaner main body 100 to the front or side of the body. The cleaning operation can be performed while positioning the
The grip portion 151a of the main body handle 151 can be adjusted to a height at which the user can perform a cleaning operation without bending the body.
In addition, since the user can perform the cleaning work while putting his / her weight on the main body handle 151, the physical burden of the cleaning work is reduced.

(Embodiment 2)
This embodiment shows the layout different from 1st Embodiment about the cleaner body 100. FIG.
FIG. 7 is a central sectional view of a vacuum cleaner according to the second embodiment of the present invention. As shown in FIG. 7, according to this embodiment, the filter 551 is disposed below the dust collection chamber 500, and the suction motor 106 is disposed below the filter 551. The air that has flowed into the dust cup 501 from the inflow port 503 passes through the filter 551 through the outflow port 533 b provided at the lower end of the inner cylinder 533 and is guided to the suction motor 106. The dust that has been centrifuged by the swirling airflow generated in the dust cup 501 accumulates at the bottom of the dust cup 501.
The air that has passed through the filter 551 and is guided to the suction motor 106 passes through the suction motor 106 from below and is then discharged to the outside through the exhaust port 133.
According to this aspect, the flow path of air becomes simpler than the first embodiment, and the resistance of the flow path can be further reduced. However, since the outflow port 533b is disposed in a portion near the lower end of the dust cup 501 that accumulates dust, it is necessary to sufficiently consider the design of the flow path so that the exhaust and dust can be reliably separated.

(Embodiment 3)
Although the vacuum cleaner 1 in 1st Embodiment and 2nd Embodiment was able to adjust the inclination | tilt angle of the housing | casing 102 and the main body handle 151 on the trolley | bogie 101, the function is not a structure essential to this invention. That is, the aspect fixed to the predetermined inclination angle may be sufficient. Although there is no restriction on the range of the tilt angle, for example, a mode in which the tilt angle is fixed to the floor surface F (that is, an angle of 90 degrees) and a mode in which the tilt angle is tilted by 15 degrees from the vertical direction can be given. .

(Embodiment 4)
Although the vacuum cleaner 1 in 1st Embodiment and 2nd Embodiment is the aspect by which the suction motor 106 is driven by AC power supply, the essence of this invention is not limited to this. For example, a mode in which a rechargeable battery is incorporated instead of the cord reel 108 and the AC power cord 160 and the suction motor 106 is driven by a DC power source is also conceivable. The battery charging terminal is preferably the upper part of the cleaner body 100 in which the AC outlet plug 131 is disposed in FIGS. 5 and 7.
If the charging terminal is exposed on the upper portion of the cleaner body 100, the user does not need to bend over when charging the battery. The physical burden at the time of charging is alleviated compared with the aspect in which the charging terminal is arranged near the floor.
