Description

The present invention relates to a gap suction port of an electric vacuum cleaner.

Patent Document 1 describes a suction tool having a shape in which the sole plate swings along the floor surface and easily comes into close contact with the floor surface even when the suction tool is pulled. In Patent Document 1, the engaging surface of the sole plate extends beyond the sole plate engaging edge and is on the same plane as the floor engaging surface so that the bottom surface of the suction tool can easily follow the floor surface (cleaning surface). Provided is a suction tool having a suction tool in which the sole plate swings when the suction tool is pushed and pulled.

Japanese Patent No. 4913879

However, the suction tool described in Patent Document 1 has a structure in which the sole plate can swing only when the sole plate is in contact with the floor surface (cleaning surface) and when a force in the rotational direction is applied to the head. For example, when the cleaning surface is not flat but has uneven surfaces (undulations) such as sofas and bedding, the sole plate cannot follow the floor surface (cleaning surface) well, and dust is efficiently used. There is a risk that you will not be able to inhale well. Further, if there is a safety device that operates to stop the rotating brush when the suction tool is separated from the cleaning surface, the safety device may operate unintentionally.
Furthermore, when the suction tool is lifted from the cleaning surface, the sole plate position does not swing from the position immediately before lifting, so the dust scraped by the rotating brush is scattered backward (downstream in the rotation direction of the rotating brush). There is also a risk that it will end up.

The present invention efficiently sucks dust and lifts the suction tool by providing a shape in which the bottom surface of the suction tool easily follows the floor surface (cleaning surface) even when cleaning the floor surface having an uneven surface (undulation). It is an object of the present invention to provide an electric vacuum cleaner which is hard to blow off dust and a gap suction port thereof.

The present invention is characterized in that it is a gap suction port connected to an electric vacuum cleaner, and the gap suction port has a light guide member.

According to the present invention, when the suction tool is lifted, the bottom surface of the suction port can easily follow the cleaning surface of a sofa or bedding having an uneven surface, so that the vacuum cleaner is easy to clean and easy to use, and the gap suction port thereof. Can be provided.

The piston portion 240 is contained in an umbrella portion 230 provided in the lower portion (front) of the tubular portion 210, and the umbrella portion 230 is provided with annular ribs (250a, 250b, 250c). The annular ribs are provided to prevent dust conveyed to the accommodating portion 2a2 from returning to the separation portion 2a1 side. In this embodiment, the annular ribs 250a and 250b are on the umbrella portion 230, and the annular ribs 250c are provided. Although it is provided in the piston portion 240, the diameter, position, and number are not limited to this. Among these plurality of annular ribs, the annular rib 250a can change the ratio of the flow that swirls the separation portion 2a1 and the flow that conveys the dust to the accommodation portion 2a2, and this also returns the dust to the separation portion 2a2 side. Effective for suppression. In order to obtain such an effect, the annular rib 250a is provided at a position facing from the substantially rectangular inflow port 2b provided in the outer cylinder 2a described above. The inflowing air (including dust) can strengthen a part of the flow that swirls the separation portion 2a1 on the upper side with the annular rib 250a as a boundary, and the lower side becomes a flow that is directly conveyed to the accommodation portion 2a2. .. In the absence of the annular rib 250a, the flow swirling around the separating portion 2a1 heads toward the accommodating portion 2a2 while swirling, and returns from the accommodating portion 2a2 to the separating portion 2a1 while traveling along the piston portion 240. At that time, the annular ribs 250b and 250c suppress the return of dust, but the dust may return to the separation portion 2a1. By providing the annular rib 250a as in the present embodiment, the swirling flow swirling around the separation portion 2a1 can be strengthened, and the dust that has returned can be suppressed from adhering to the mesh portion 220 of the inner cylinder 200.

In the present embodiment, the annular rib 250a is provided at a position slightly facing the inflow port 2b, but the present invention is not limited to this, and the position where the inflow port 2b is divided into two may be used. Further, although the annular rib 250a is provided in the umbrella portion 240, it may be provided in the tubular portion 210 provided with the mesh portion 220 instead of the umbrella portion 240.

Further, on the front surface of the dust case 2, a lid 2c that opens and closes when the dust accumulated in the dust case 2 is discarded is rotatably supported via a hinge portion 2d. Further, a lid lock mechanism 2e provided with a release button 2f for unlocking the lid 2c is provided on the upper portion of the lid 2c.

In the dust case 2, the filter 5 is housed at the rear end in the axial direction of the outer cylinder 2a. The filter 5 is configured to be folded in a pleated shape, so that the filter area can be increased and the pressure loss due to the filter 5 can be reduced. Further, the filter 5 can be removed by pressing the button 5a provided on the upper part of the dust case 2, and the dust case 2 from the vacuum cleaner main body 1 is on the side facing the button 5a (lower side in the arrow in the figure). It is provided with a button 5b for removing.

The HEPA filter is an air filter having a particle collection rate of 99.97% or more with respect to particles having a rated air volume of 0.3 μm and an initial pressure loss of 245 Pa or less.
The internal mechanism of the dust case 2 can be configured based on JP-A-2016-137165.

FIG. 3 is a perspective view showing an electric vacuum cleaner in a state where the above-mentioned lid lock mechanism 2e is operated and the lid 2c is opened. FIG. 4 is a vertical sectional view of the vacuum cleaner, and FIG. 5 is a side view.
As shown in FIGS. 3 to 5, in the vacuum cleaner 100, the dust case 2 is attached below the main body portion 10 and in front of the motor case portion 11. In this case, when the dust case 2 is attached to the vacuum cleaner main body 1, the lid lock mechanism 2e is provided on the upper side indicated by the arrow in the figure, and the hinge portion 2d is provided on the lower side. Further, the release button 2f provided in the lid lock mechanism 2e is located at a position facing from the left side of the vacuum cleaner main body 1 (main body portion 10), behind the side surface of the main body portion 10, in other words, at a position not protruding from the side surface of the main body portion 10. Be prepared. This is because if the release button 2f is provided at a position protruding from the side surface of the main body 10, the lid 2c may be released during cleaning, but the release button 2f is prevented from protruding from the side surface of the main body 10. This is because malfunction can be prevented. For example, the vacuum cleaner body 1 may touch furniture or the like during cleaning. At this time, since the release button 2f is provided on the back side of the side surface of the main body portion 10, it is unlikely that the lid 2c will be opened unintentionally without accidentally touching the release button 2f by furniture or the like. The position of the release button 2f provided in the lid lock mechanism 2e is not limited to this, and may be provided at a position facing from the right side of the vacuum cleaner main body 1. As in the present invention, by adopting a structure in which the release button 2f can be pressed from the side surface of the main body 10, dust in the dust case 2 can be easily discharged by one operation at a waste disposal site such as a trash can.

Further, the dust case removal button 5b shown in FIGS. 4 and 5 described above can be slid in the forward direction indicated by the arrow in the figure to remove the dust case 2 from the vacuum cleaner main body 1. This makes it possible to carry only the dust case 2 and dispose of it even when the vacuum cleaner main body 1 is standing on the charging stand 70 (during charging). Further, since only the dust case 2 can be removed from the vacuum cleaner main body 1, it can be easily washed with water when the dust case 2 is dirty, so that the dust case 2 can be kept clean. As described above, according to the present invention, it is possible to dispose of dust according to the state in which the dust case 2 is attached to the vacuum cleaner main body 1, the state in which the dust case 2 is removed, and the situation of the user. can do.

Further, the dust case 2 is provided with a care brush 2s detachably provided. The care brush 2s is arranged at a position where it is difficult to see from the outside when the dust case 2 is attached to the vacuum cleaner main body 1. Therefore, it does not easily come off during operation, and it is not necessary to store the care brush 2s in a place different from the vacuum cleaner 100.

As shown in FIG. 4, the electric blower 40 is housed in the motor case portion 11 of the main body portion 10. In the motor case portion 11, a main body board 50 (control board) for controlling the vacuum cleaner main body 1 is housed below the electric blower 40.

The electric blower 40 is arranged horizontally so that the rotary drive shaft 40a faces in the front-rear direction. Further, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 to cool the main body substrate 50.

The main body board 50 is divided into upper and lower parts and arranged in two stages, and components are mainly mounted on opposite surfaces. Most of the air discharged from the electric blower 40 flows so as to cool the parts (heat generating parts) arranged opposite to each other on the main body board 50.

Further, the electric blower 40 and the main body substrate 50 are arranged so as to overlap each other in the vertical direction. Therefore, the dimensions in the front-rear direction can be shortened. Further, the electric blower 40 and the main body substrate 50 are located below the first grip portion 12a1 of the handle portion 12. As a result, when the user grips and operates the grip portion 12a1, the center of gravity of the vacuum cleaner 100 is near the lower side of the first grip portion 12a1. Therefore, when the tip of the vacuum cleaner 100 is used upward, the vacuum cleaner 100 is cleaned. The machine 100 can be stably held.

Further, a gap 12c having a width dimension H1 for inserting a hand is formed between the first grip portion 12a1 and the upper surface 11c of the motor case portion 11. Further, a gap 12d having a width dimension H2 wider than the width dimension H1 is formed between the second grip portion 12a2 and the back surface 11d of the motor case portion 11. In this way, when the first grip portion 12a1 is gripped and cleaned, the arm can be held in an extended state, so that the vacuum cleaner 100 can be moved back and forth without firmly gripping the first grip portion 12a1. can. Further, when the second grip portion 12a2 is gripped and cleaned, it is necessary to insert a hand (finger) deeply into the gap 12d and grip it strongly. Therefore, by making the width dimension H2 wider than the width dimension H1. The second grip portion 12a2 can be stably gripped.

Further, the thickness T1 of the first grip portion 12a1 is formed to be thin, and the thickness T2 of the second grip portion 12a2 is formed to be thicker than the thickness T1. That is, the first grip portion 12a1 is formed to be thin, and the second grip portion 12a2 is formed to be thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the thickness T2 of the second grip portion 12a2 can be increased to facilitate deep grip and increase the strength of the second grip portion 12a2. can.

The storage battery 3 can be composed of, for example, a lithium ion battery having high energy efficiency. Further, the storage battery 3 is arranged below the second grip portion 12a2 of the handle portion 12. By providing the storage battery 3 at the rear end of the vacuum cleaner 100 in this way, the center of gravity of the handle portion 12 becomes closer to the second grip portion 12a2. Can be lightened.

The storage battery lock member 13 has a claw portion 13a that is locked to the storage battery 3 on the free end side. Further, the storage battery lock member 13 is arranged so as to surround the back surface of the storage battery 3 from the upper end to the lower end, and is configured to lock the claw portion 13a and the lower surface of the storage battery 3 on the lower surface of the rear end of the storage battery 3.
By making the storage battery 3 removable in this way, it becomes easier to replace the storage battery 3 as compared with a non-detachable storage battery. In addition, by preparing a spare storage battery 3 and a charging box that can charge the spare storage battery 3 as an option, if the storage battery on the main body side of the vacuum cleaner 100 is exhausted, it can be immediately replaced with the spare storage battery 3. , It becomes possible to extend the cleaning time. This configuration is effective, for example, when cleaning a wide floor surface such as a store.

The front surface of the holding portion 83b is formed so as to be curved toward the front while spreading to the left and right.

FIG. 16 is a side view showing a charging stand of a vacuum cleaner.
As shown in FIG. 16, the charging stand 70 inserts the pipe 81 into the connecting holding portion 72c from above with the connecting terminal portion 82a of the relay terminal 82 facing forward. Then, when the connecting portion 81s (see FIG. 15) of the pipe 81 below the relay terminal 82 is inserted into the connecting holding portion 72c, the first charging terminal 73 (see FIG. 15) is fitted to the relay terminal 82, and the first charging terminal 73 is fitted to the relay terminal 82. 1 The charging terminal 73 and the relay terminal 82 are electrically connected. Further, the relay terminal 82 is electrically connected to the second charging terminal 83 via an electric wire (not shown) passed through the pipe 81.

At this time, in the side view of FIG. 16, the position of the back surface (rear surface) of the connection holding portion 72c and the position of the back surface (rear surface) of the extension member 80 are substantially the same. Further, the extending portion 71e is configured so as to project rearward from the connecting holding portion 72c and the extension member 80 in the side view of FIG.

Further, the upper surface 83a1 of the holding portion 83a is slightly inclined so as to descend toward the front. Further, the second charging terminal 83 is arranged so as to be inclined along the inclination of the upper surface 83a1.

FIG. 17 is a side view when the vacuum cleaner is attached to the charging stand in a stick state. The direction arrow in FIG. 17 indicates the direction of the charging stand 70 (the same applies to FIG. 18).
As shown in FIG. 17, the vacuum cleaner 100 is charged by being connected to the second charging terminal 83 in the stick state. At this time, the user turns the extension tube 300 downward while grasping the handle portion 12, and lowers the vacuum cleaner main body 1 from above the second charging terminal 83 so that the main body terminal portion 17 is connected to the second charging terminal 83. Is connected. At this time, since the second charging terminal 83 is formed upward, the main body terminal portion 17 can be reliably connected to the second charging terminal 83 by the own weight of the vacuum cleaner 100.

Further, the dust case 2 is in contact with the holding portion 83b, and the extension pipe 300 is held by the extension pipe holding portion 82c of the extension member 80. Further, a part of the standard suction port 400 is in contact with the mounting surface 71a of the base portion 71. As a result, even when charging with the vacuum cleaner 100 in a high center of gravity, the vacuum cleaner 100 can be stably held in the charging stand 70.

Further, when the vacuum cleaner 100 in the stick state is charged by the charging stand 70, the vacuum cleaner 100 is held in a posture of being tilted forward by an angle α with respect to the vertical direction (vertical direction). In this way, when the vacuum cleaner 100 is held in the forward leaning posture, the center of gravity of the vacuum cleaner 100 is closer to the front than when the vacuum cleaner 100 is held upright. You can prevent it from falling backwards.

The charging stand 70 can be used as a stand for storing the vacuum cleaner 100 even when the power cord 76 is not connected and the storage battery 3 is not charged.

FIG. 18 is a side view when the vacuum cleaner is attached to the charging stand in a handy state.
As shown in FIG. 18, the vacuum cleaner 100 is connected to the first charging terminal 73 in the handy state. That is, in the state of charging the vacuum cleaner 100 in the stick state shown in FIG. 17, the extension member 80 is attached to the stand portion 72 with the connecting terminal portion 82a facing backward (reverse direction). That is, from the state shown in FIG. 16, the extension member 80 is pulled upward until the connection between the first charging terminal 73 (see FIG. 15) and the relay terminal 82 is released. Then, the extension member 80 is rotated around the pipe 81 so that the relay terminal 82 faces the rear side, and is lowered until it comes into contact with the upper surface 72a, so that the state shown in FIG. 18 is obtained.

Then, the extension pipe 300 is removed from the vacuum cleaner 100, and the vacuum cleaner 100 and the standard suction port 400 are directly connected. Then, by lowering the main body terminal portion 17 of the vacuum cleaner 100 to which the standard suction port 400 is connected from above the first charging terminal 73, the first charging terminal 73 is connected to the main body terminal portion 17. As described above, in the charging stand 70 of the present embodiment, the extension member 80 can be stored in a different direction, and the vacuum cleaner 100 can be charged in a handy state. Further, since the extension member 80 is not stored in a place different from the charging stand 70, the usability can be improved.

The extension tube 300 can be held and stored in the extension tube holding portion 82c of the extension member 80. In this way, the extension member 80 can be held by the extension tube holding portion 82c of the charging stand 70, so that when the vacuum cleaner 100 is changed from the stick state to the handy state, the removed extension tube 300 is extended. It can be quickly attached to the tube holding portion 82c and stored. Further, when the vacuum cleaner 100 is changed from the handy state to the stick state, the extension pipe 300 can be removed from the extension pipe holding portion 82c and quickly attached to the vacuum cleaner 100. Further, since the extension pipe 300 can be held at a position higher than the floor surface, it can be easily attached and detached by the user, and the usability can be improved. Further, since it is not necessary to store the extension tube 300 in a place different from the charging stand 70, usability can be improved.

FIG. 19 is a cross-sectional view showing a connection state between the main body terminal portion and the first charging terminal.
As shown in FIG. 19, when the main body terminal portion 17 is fitted to the first charging terminal 73, the main body terminal 17d comes into contact with the terminal 73c, and the edge portion 17f of the main body terminal 17d is further lowered to cause the terminal 73c to move. It bends backward and deforms. Since the terminal 73c has a spring property of urging toward the front, the main body terminal 17d and the terminal 73c are maintained in contact with each other while the vacuum cleaner main body 1 is mounted on the charging stand 70. , Charging of the storage battery 3 (see FIG. 3) is continued.

Further, since the first charging terminal 73 is unevenly fitted with the main body terminal portion 17, for example, even if the user comes into contact with the vacuum cleaner main body 1 during charging, the main body terminal 17d and the terminal 73c are in a conductive state. (Contact state) is not released. Further, even when the second charging terminal 83 (see FIG. 16) is connected to the main body terminal portion 17, even if the user comes into contact with the vacuum cleaner main body 1 during charging, the main body terminal 17d and the terminal 73c are in a conductive state. (Contact state) is not released.

In the charging stand 70 configured in this way, since the first charging terminal 73 is formed on the upper surface 72a of the stand portion 72, the user's line of sight when the first charging terminal 73 and the main body terminal portion 17 are aligned. Since it is located close to, it becomes easy to insert the main body terminal portion 17 into the first charging terminal 73, and it becomes easy to set the vacuum cleaner main body 1 on the charging stand 70. Further, in the charging stand 70, since the second charging terminal 83 is formed on the upper surface 83a1 (see FIG. 15), it is closer to the user's line of sight when the second charging terminal 83 and the main body terminal portion 17 are aligned. Since it is in the position, it becomes easy to insert the main body terminal portion 17 into the second charging terminal 83, and it becomes easy to set the vacuum cleaner main body 1 on the charging stand 70.

Further, in the charging stand 70, the first charging terminal 73 is formed on the upper surface 72a of the stand portion 72. That is, since the first charging terminal 73 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the first charging terminal 73, and it is also possible to reduce the amount of dust rising from the floor surface and adhering to the first charging terminal 73. Further, in the charging stand 70, the second charging terminal 83 is formed on the upper surface 83a1 of the extension member 80. That is, since the second charging terminal 83 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the second charging terminal 83, and it is possible to reduce the amount of dust rising from the floor surface and adhering to the second charging terminal 83.

Further, in the vacuum cleaner 100 set on the charging stand 70, the first charging terminal 73 and the second charging terminal 83 are located at positions close to the center of gravity of the vacuum cleaner 100 (positions of the electric blower 40 and the storage battery 3). By receiving the vicinity of the center of gravity by the first charging terminal 73 and the second charging terminal 83, the vacuum cleaner main body 1 can be stably held on the charging stand 70 during charging.

Further, by applying the vacuum cleaner 100 to the charging stand 70, the dust case 2 can be charged in a removed state, so that the dust case 2 can be charged even while it is being washed and dried.

Further, when the vacuum cleaner 100 is charged in a handy state on the charging stand 70, the standard suction port 400 does not come into contact with the mounting surface 71a of the base portion 71 (see FIG. 18). Further, the first charging terminal 73 faces upward, and the main body terminal portion 17 is connected to the first charging terminal 73 from above. As a result, the weight of the vacuum cleaner 100 can be applied to the first charging terminal 73 in a focused manner, so that the main body terminal portion 17 and the first charging terminal 73 can be reliably connected.

Although not shown, when the vacuum cleaner 100 is charged in the stick state, the main body terminal portion 17 of the vacuum cleaner 100 and the second charging terminal 83 are connected by the same mechanism as in FIG. NS. Therefore, even when the main body terminal portion 17 and the second charging terminal 83 are connected, the same effect as when the first charging terminal 73 and the main body terminal portion 17 are connected can be obtained.

Further, in the charging stand 70, when charging with the standard suction port 400 connected to the vacuum cleaner 100, the vacuum cleaner 100 can be supported by the mounting surface 71a of the base portion 71, so that the vacuum cleaner 100 is standard with the first charging terminal 73. It can be supported at two points of the suction port 400, and the vacuum cleaner 100 can be stably held on the charging stand 70.

FIG. 20 is a usage diagram when cleaning the floor surface with a vacuum cleaner in a stick state.
As shown in FIG. 20, when the vacuum cleaner 100 is put into a stick state and the vacuum cleaner 100 is projected forward from the user to clean the floor surface, the user has to use the second grip portion of the handle portion 12. While gripping 12a2, move the vacuum cleaner 100 back and forth. Further, although not shown, when cleaning the floor surface with the vacuum cleaner 100 located beside the user, the user holds the first grip portion 12a1 of the handle portion 12 while electrically performing the cleaning. Move the vacuum cleaner 100 back and forth. In this way, when the user cleans the floor surface, the position of the handle portion 12 can be changed for cleaning.

FIG. 21 is a usage diagram when cleaning a high place with a vacuum cleaner in a stick state.
By the way, in the vacuum cleaner (see Patent Document 1) in which the center of gravity is on the tip side when the stick state is set, when the vacuum cleaner 100 is cleaned at a place higher than the floor surface, the user of the vacuum cleaner 100 Since it is necessary to lift the tip upward, it is easy to put a burden on the wrist.
Therefore, as shown in FIG. 21, since the electric blower 40 (see FIG. 4) and the storage battery 3 which are heavy objects of the vacuum cleaner 100 are located at a position close to the handle portion 12 (a position close to the hand), the vacuum cleaner 100 The center of gravity G of is closer to the user's hand. As a result, even when the vacuum cleaner 100 is put into a stick state and the vacuum cleaner 100 is cleaned in a place higher than the floor surface, it becomes easy to clean and the usability can be improved. In FIG. 21, the case of cleaning the stairs has been described as an example, but it is also effective when the vacuum cleaner 100 is lifted to clean the panel of the air conditioner or the like.

Next, various applied mouthpieces connected to the vacuum cleaner 100 will be described. Various applied mouthpieces can be connected to and replaced with the electric vacuum cleaner 100 as an accessory for cleaning.
22A and 22B show a cross-sectional view showing a standard mouthpiece to which an opening / closing member is attached, where FIG. 22A is for forward movement, FIG. 22B is for wall contact, and FIG. 22C is for reverse movement. In FIG. 22, the motor for driving the rotary brush and the substrate for controlling the rotary brush are not shown.

As shown in FIG. 22A, the standard mouthpiece 400 includes a mouthpiece case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 that rotates due to friction with the floor surface. Has and is configured.

The mouthpiece case 401 has an open lower surface and a space for accommodating the first brush 402 and the second brush 403. The second brush 403 is arranged with a gap behind the first brush 402.

Further, an opening / closing member 404 is provided on the front surface of the mouthpiece case 401. The opening / closing member 404 has a rotation shaft 404a. Further, the opening / closing member 404 has a protrusion 404b extending perpendicular to the axial direction of the rotation shaft 404a, and an opening / closing body 404c extending from the rotation shaft 404a in the direction opposite to the protrusion 404b. The protrusion 404b is made of a hard plate-shaped member. The opening / closing body 404c is configured by stacking a brush portion 404c1 on the front side and a rubber plate 404c2 on the rear side in the front-rear direction.

As shown in FIG. 22A, when the standard suction port 400 is advanced, the opening / closing body 404c is counterclockwise due to the frictional force between the brush portion 404c1 and the floor surface and the suction force of the electric blower 40. By rotating, the lower part of the front surface of the mouthpiece case 401 is opened. By opening the opening / closing body 404c in this way, it becomes possible to suck in large dust (dust) located in front of the standard suction port 400.

As shown in FIG. 22B, when the standard suction port 400 hits the wall, the tip (upper end) of the protrusion 404b first hits the wall. Then, when the standard suction port 400 is further pressed toward the wall, the opening / closing member 404 rotates clockwise due to the pushing force at this time, and the opening / closing body 404c operates forward. When the opening / closing body 404c operates forward, the opening 401a at the lower front surface of the mouthpiece case 401 is closed. With this configuration, dust near the wall (corner) can be sucked in and removed. Further, by moving the standard suction port 400 in the left-right direction, dust near the wall can be removed more reliably.

As shown in FIG. 22 (c), when the standard suction port 400 is moved backward, the opening / closing body 404c rotates clockwise due to the frictional force between the brush portion 404c1 and the floor surface, and the opening / closing body 404c faces forward. Works on. As a result, the static pressure inside the suction case 401 increases, so that dust can be reliably sucked.

Further, in the cordless vacuum cleaner 100, the suction power is weaker than that of the vacuum cleaner in which electric power is supplied from a household outlet. For this reason, in the standard mouthpiece 400, the front surface (opening 401a) of the mouthpiece case 401 is opened when moving forward (see FIG. 22A), so that the operating force can be lightened and large dust can be sucked. can. Further, when moving backward (see FIG. 22C), the opening / closing member 404 closes and the static pressure increases, so that, for example, sand dust in the carpet can be sucked in firmly. Further, by making the standard suction port 400 smaller than the suction port connected to the vacuum cleaner that supplies power from a household outlet, air leakage from the standard suction port 400 can be reduced and the static pressure can be evenly distributed. It will be easier to get around.

FIG. 23 shows various applied mouthpieces, (a) a perspective view showing a gap mouthpiece, (b) a perspective view showing a small mouthpiece, and (c) a perspective view showing a broom-type mouthpiece.
As shown in FIG. 23A, the gap suction port 500 sucks dust accumulated between furniture or in a gap between furniture and a wall. Further, the gap suction port 500 has a circular tubular main body connection port 501 connected to the vacuum cleaner 100 at the base end, and a narrow suction port 502 directed to the suction object at the tip end.

As shown in FIG. 23 (b), the small mouthpiece (mini power head) 600 is a substantially smaller version of the standard mouthpiece 400 described above, and it is necessary to clean the same place as the place used by the standard mouthpiece 400. It can be applied to places with physical resistance (sofa, bedding, etc.).

Further, the small mouthpiece 600 includes a mouthpiece cover 601 narrower than the standard mouthpiece 400 and a rotary brush 603 rotated by a small mouthpiece motor 606 (see FIG. 24A). Further, the small suction port 600 includes a joint portion 604 having a terminal electrically connected to the vacuum cleaner 100.

FIG. 23 (c) is a broom-type suction port 700 for cleaning the rail of the sash, the inside of the drawer in which small items are stored, and the like. The broom-type suction port 700 is connected to a front portion 700a having a brush body 701 for sweeping dust, a tube 702 made of a flexible material such as a rubber material or an elastomer for sucking dust, and a vacuum cleaner 100. It is composed of a rear portion 700b having a connecting portion 703. The connection portion 703 of the rear portion 700b is fitted to the introduction pipe 14 of the vacuum cleaner 100 shown in FIG. 2, and the contact portion 14a is in contact with the contact portion cover 705 in a state where the broom type suction port 700 is attached to the vacuum cleaner 100. .. At this time, the contact portion 14a and the contact portion cover 705 are in contact with each other without a gap, thereby suppressing the entry of dust or the like into the contact portion 14a.

The front portion 700a and the rear portion 700b are connected by a joint portion 704, and the orientation of the front portion 700a having the brush body 701 and the tube 702 can be changed. From the state where the rear portion 700b is fixed, the front portion 700a can be rotated 360 degrees, FIG. 37 (a) is a side view of FIG. 23 (c), and FIG. 37 (b) is a front view of FIG. 37 (a). The portion 700a is rotated 180 degrees. The XX line shown in FIG. 37 is the center line of the rear portion 700b and is horizontal to the front-back direction of the arrow shown in the figure. The YY line shown in FIG. 37 is the center line of the front portion 700a. The angle θ consisting of the XX line and the YY line changes when the front portion 700a is rotated, and rotates in the range of 15 degrees to 50 degrees. In the present embodiment, the front portion 700a can be further downwardly rotated by rotating from a state facing downward by 15 degrees or more from the front-rear direction, but this is not the case, and the front portion 700a is rotated downward from a substantially horizontal direction. May be. This broom-type suction port 700 is assumed to be cleaned by pulling it from the front to the rear, and the brush body 701 and the tube 702 are always downward when viewed from the front-rear direction within the movable range, as described above. Easy to clean.

The front portion 700a described above is configured to cover a plurality of tubes 702 with a brush body 701. In this embodiment, the tubes 702 are arranged in two rows in the vertical direction of the arrows in the figure of FIG. 23 (c) and three in the horizontal direction, for a total of six tubes. The brush body 701 is about 5 mm longer than the tip of the tube 702. If the brush body 701 is shorter than the tip of the tube 702, the cleaning surface may be rubbed with the tube 702, and a flexible material such as a rubber material or an elastomer may adhere to the cleaning surface. Further, when the brush body 701 is too long than the tip of the tube 702, the tip of the tube 702 is greatly separated from the cleaning surface in a state where the brush body 701 is in contact with the cleaning surface, and the suction force is weakened. Therefore, it is desirable that the distance between the brush body 701 and the tip of the tube 702 is about 3 to 5 mm, that the brush body 701 is longer than the tip of the tube 702. However, the distance between the brush body 701 and the tip of the tube 702 is not limited to this because it is affected by the suction force of the vacuum cleaner 100.

FIG. 38 is a perspective view showing only the tube 702 of the broom-type mouthpiece 700. Further, the A view shown in FIG. 38 is shown in FIG. 39 (a), and the B view is shown in FIG. 39 (b). The tube 702 has a diameter that does not suck in small articles, and in this embodiment, it has a substantially cylindrical shape with both ends open at about 8 mm, and fluidly communicates with the vacuum cleaner 100, and the front portion 700a is from the tube end portion 710. Only suck air. The tube 702 has a substantially cylindrical shape, but may have a rectangular or polygonal cross section.

As shown in FIG. 39 (a), the tube end portion 710 is provided with a wave-shaped portion 720 that looks substantially S-shaped when viewed from A. The wave-shaped portion 720 has a shape in which arcs having a diameter of about 5 mm are connected. For example, when the tube end 710 is cut diagonally, if the tube end 710 is brought close to the cleaning surface at the same inclination as the cut angle, it may stick to the cleaning surface. However, by providing the wave-shaped portion 720 at the tube end portion 710 as in the present embodiment, a gap is always formed when the tube end portion 720 comes into contact with the cleaning surface, and it is possible to suppress sticking to the cleaning surface. When such a wave-shaped portion 720 is provided, a concave portion 730 and a convex portion 740 are formed as shown in B view, so that a gap can be further provided. In this embodiment, the wave-shaped portion 720 is set to about 5 mm, but this is not the case because the wave-shaped portion 720 changes with the diameter of the tube 702.

Further, as described above, in this embodiment, six tubes 702 are provided, and the tubes are set to 702a to 702f, respectively. In the tube 702a, the concave portion 730 is arranged on the substantially front side and the convex portion 740 is arranged on the substantially back side when viewed from B. In the tube 702c, the concave portion 730 is arranged on the substantially back side and the convex portion 740 is arranged on the substantially front side when viewed from B view. Will be. In the tube 702b, the concave portion 730 is arranged on the substantially back side and the convex portion 740 is arranged on the substantially front side when viewed from A. The tube 702d has substantially the same arrangement as the tube 702a, and the tube 702f has substantially the same arrangement as the tube 702c. In the tube 702e, the concave portion 730 is arranged on the substantially front side and the convex portion 740 is arranged on the substantially back side when viewed from A. As a result, since the concave portion 730 and the convex portion 740 do not face in the same direction, the tube end portion 710 is not squeezed when entering the corner portion, and a decrease in suction force can be suppressed.

By forming the tube end 720 in this way, it does not stick to the cleaning surface as described above, and it suppresses the sticking of small items such as coins, so that the rail of the sash and the drawer where the small items are stored can be stored. Easy to clean.

FIG. 24A is an external view of the small mouthpiece as viewed from below, and FIG. 24B is a cross-sectional view taken along the line MM shown in FIG. 24A.
As shown in FIGS. 24A and 24B, the appearance of the small mouthpiece 600 is composed of a mouthpiece cover 601, a lower case 602, a rotary brush 603, and a joint portion 604, and the lower case 602 houses the rotary brush 603. A suction chamber 602a to be used, a safety switch 605 for stopping the rotation of the rotary brush 603 when the small suction port 600 is lifted, a small suction motor 606, a substrate (not shown), and the like are housed inside.
In the rotary brush 603, a brush is planted on the outer periphery of a core member provided at the center of the shaft, and the structure is omitted, but the rotary brush 603 is detachably supported by the shaft. Therefore, the entanglement of hair and the like can be easily removed, the brush can be washed with water, and the rotating brush 603 can be kept clean.

The suction chamber 602a for accommodating the rotary brush 603 is a space having a substantially semicircular shape so as to follow the shape of the rotary brush 603, and an opening is provided in the substantially center of the partition wall forming the suction chamber 602a. The opening fluidly communicates with the joint 604. On the inflow port side (front side) of the joint portion 604, a joint portion inflow port 604a formed concentrically so as to offset the partition wall forming the suction chamber 602a of the lower case 602 is provided. Therefore, the joint inlet 604a can be rotatably (rotatably) moved within a movable range along the arc surface of the partition wall forming the suction chamber 602a. In other words, the joint inlet 604a can be rotatably moved within a movable range on substantially coaxial with the rotary brush 603. Further, within the movable range, the joint inflow port 604a communicates with the opening of the suction chamber 602a. The small mouthpiece 600 shown in FIG. 23 (b) is in a state in which the joint portion 604 is also rotated backward, and the MM cross-sectional view of the small mouthpiece 600 shown in FIG. 24 (b) is also in front of the joint portion 604. It is in a state of being rotated to.

As described above, the small suction motor 606 and the safety switch 605 are provided behind the suction chamber 602a. Further, in the joint portion 604, the front joint portion inflow port 604a can be rotatably moved. Therefore, since the rotation shaft of the joint portion 604 is in front of the small mouthpiece 600 and the heavy small mouthpiece motor 606 and the like are in the rear, when the small mouthpiece 600 is lifted, the small size is centered on the rotation shaft of the joint portion 604. The rear of the mouthpiece 600 can move downward due to its own weight.
In this way, when the small mouthpiece 600 is lifted, the rear side of the small mouthpiece 600 moves downward under its own weight around the rotation axis of the joint portion 604, so that the bottom surface of the small mouthpiece 600 follows the unevenness of the sofa or bedding. The safety switch 605 can be cleaned without being easily activated.
Further, when the small suction port 600 is lifted, before the rotary brush 603 stops, the rotation of the rotary brush 603 causes large granular dust (for example, rice grains) to be moved backward (downstream side in the rotation direction of the rotary brush 603a). Although it may be blown off and scattered, even if granular dust is repelled by the rear side of the small mouthpiece 600 moving downward by its own weight, it can be suppressed because it collides with the lower case 602. At that time, it is desirable that the safety switch 605 is located in front of the rear end of the lower case 602 so that the rear of the small mouthpiece is lifted after the rotary brush is stopped.

In this embodiment, the rotation axis of the joint portion 604 is made rotatable substantially coaxially with the rotary brush 603, and the small mouthpiece motor 606 is located behind the suction chamber 602a. However, this is not the case, and the rotation of the joint portion 604 is not limited to this. The shaft may be located in front of the center of gravity of the small mouthpiece 600. Further, the safety switch 605 may be positioned behind the rotation axis of the joint portion 604, and is not limited to being located behind the suction chamber 602a. Further, when the rotation direction 603a of the rotation brush 603 is reverse rotation, the above-mentioned front-back relationship may be reversed.
Further, as an additional means for preventing the safety switch 605 from unintentionally and excessively operating when cleaning the uneven surface, the safety switch 605 does not stop the rotating brush at the same time as the safety switch 605 separates from the cleaning surface, and the safety switch 605 A time lag may be provided before the operation of. As for the method of providing the time lag, for example, a time lag may be provided for control so that the safety switch 605 operates when the safety switch 605 is separated from the cleaning surface for several seconds, or a capacitor is provided in the circuit of the safety switch 605. A time lag may be provided at.
