It is a sectional view taken along the JJ line shown in b).

The dust case 2 includes an outer cylinder 2a and an inner cylinder 200, which will be described later. The outer cylinder 2a has a substantially cylindrical shape, and as described above, has a substantially rectangular inlet 2b on the upper surface (cylindrical side surface), is open at the front and back, has a filter 5 to be described later at the rear, and has a lid 2c at the front. Equipped with. Further, as shown in FIG. 36(a), the rear part is divided into a separation part 2a1 that swirls and separates the air containing dust sucked from the inlet 2b, and the front part is divided into a storage part 2a2 that stores the separated dust.

The inner cylinder 200 has a substantially cylindrical shape as shown in FIG. 36, and has a cylindrical part 210 provided with a mesh part 220 at the upper part (backward), and a cylindrical part 210 provided with a mesh part 220 at the lower part (front), but when the lid 2c is opened. It is equipped with a piston part 240 that pushes out dust. The piston part 240 is enclosed in an umbrella part 230 provided at the lower part (front) of the cylindrical part 210, and the umbrella part 230 is provided with annular ribs (250a, 250b, 250c). The annular ribs are provided to make it difficult for the dust conveyed to the storage section 2a2 to return to the separation section 2a1 side. In this embodiment, the annular ribs 250a and 250b are attached to the umbrella section 230, and the annular ribs 250c are attached to the umbrella section 230. 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 swirling around the separation part 2a1 and the flow conveyed to the storage part 2a2, and this also prevents dust from returning to the separation part 2a2 side. Effective in suppressing In order to obtain such an effect, the annular rib 250a is provided at a position facing the substantially rectangular inlet 2b provided in the aforementioned outer tube 2a. With the annular rib 250a as a boundary, the flow of the inflowing air (including dust) can strengthen part of the flow that swirls around the separating section 2a1 on the upper side, and the flow that is directly conveyed to the storage section 2a2 on the lower side. . In the absence of the annular rib 250a, the flow swirling through the separating section two a1 heads toward the accommodating section two a2 while swirling, and returns from the accommodating section two a2 to the separating section two a1 while passing along the piston section 240. At this time, although the annular ribs 250b and 250c prevent the dust from flying back, the dust may return to the separating portion 2a1. By providing the annular rib 250a as in this embodiment, it is possible to strengthen the swirling flow that swirls around the separating section two a1, and it is possible to suppress the returning dust from adhering to the mesh section 220 of the inner cylinder 200.

In this embodiment, the annular rib 250a is provided at a position slightly facing from the inlet 2b, but the present invention is not limited to this, and the annular rib 250a may be located at a position that bisects the inlet 2b. Further, although the annular rib 250a is provided on the umbrella portion 240, it may be provided on the cylindrical portion 210 including the mesh portion 220 instead of the umbrella portion 240.

Further, on the front surface of the dust case 2, a lid 2c that is opened and closed when disposing of the dust accumulated in the dust case 2 is rotatably supported via a hinge portion 2d. Furthermore, a lid locking mechanism 2e is provided on the top of the lid 2c, and includes a release button 2f for unlocking the lid 2c.

A filter 5 is housed in the dust case 2 at the rear end of the outer cylinder 2a in the axial direction. This filter 5 is constructed by folding into a pleat shape, so that the filter area can be increased and pressure loss due to the filter 5 can be reduced. The filter 5 can be removed by pressing the button 5a provided on the top of the dust case 2, and the dust case 2 is removed from the vacuum cleaner main body 1 on the side opposite the button 5a (lower side in the arrow in the figure). It is equipped with a button 5b for removing.

Further, the filter 5 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). A HEPA filter is an air filter that has a particle collection rate of 99.97% or more for particles with a particle size of 0.3 μm at a rated air flow rate and an initial pressure loss of 245 Pa or less.

Note that the internal mechanism of the dust case 2 can be configured based on Japanese Patent Application Publication No. 2016-137165.

FIG. 3 is a perspective view showing the vacuum cleaner with the lid 2c opened by operating the lid locking mechanism 2e described above. FIG. 4 is a longitudinal 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 part 10 and in front of the motor case part 11. In this case, when the dust case 2 is attached to the cleaner body 1, the lid locking mechanism 2e is provided on the upper side as indicated by the arrow in the figure, and the hinge portion 2d is provided on the lower side. Further, the release button 2f of the lid locking mechanism 2e is located at a position facing from the left side of the vacuum cleaner body 1 (main body part 10), and is located further back than the side surface of the main body part 10, in other words, at a position that does not protrude from the side surface of the main body part 10. Be prepared. This is because if the release button 2f is provided in a position that protrudes from the side surface of the main body 10, there is a risk that the lid 2c will be released during cleaning. This is because malfunctions can be prevented. For example, during cleaning, the cleaner body 1 may come into contact with furniture or the like. At this time, since the release button 2f is provided further back than the side surface of the main body 10, furniture or the like will not accidentally touch the release button 2f, and the possibility that the lid 2c will open unintentionally is low. The position of the release button 2f provided in the lid locking mechanism 2e is not limited to this, and may be provided at a position facing from the right side of the cleaner body 1. By configuring the release button 2f to be pushed from the side of the main body 10 as in the present invention, the dust in the dust case 2 can be easily discharged with 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 shown by the arrow in the figure to remove the dust case 2 from the cleaner body 1. This makes it possible to carry only the dust case 2 and throw away garbage even when the vacuum cleaner main body 1 is standing on the charging stand 70 (during charging). Moreover, since only the dust case 2 can be removed from the vacuum cleaner main body 1, if the dust case 2 is dirty, it can be easily washed with water, so that the dust case 2 can be kept clean. As described above, according to the present invention, garbage can be disposed of depending on the user's situation, such as when the dust case 2 is attached to or removed from the vacuum cleaner main body 1, thereby providing an easy-to-use vacuum cleaner. can do.

Further, a cleaning brush 2s is detachably provided in the dust case 2. This cleaning 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 cleaner body 1. Therefore, it is difficult to come off during operation, and there is no need to store the cleaning brush 2s in a separate location from the vacuum cleaner 100.

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

The electric blower 40 is placed horizontally so that the rotational 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 disposed 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 opposing surfaces. Most of the air discharged from the electric blower 40 flows to cool the components (heat generating components) disposed opposite to each other on each main body board 50 .

Moreover, the electric blower 40 and the main body board 50 are arranged so as to overlap in the vertical direction. Therefore, the dimension in the front and back direction can be shortened. Further, the electric blower 40 and the main body board 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 part 12a1, the center of gravity of the vacuum cleaner 100 is located near the bottom of the first grip part 12a1, so when the user uses the vacuum cleaner 100 with the tip facing upward, The machine 100 can be held stably.

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

Moreover, the thickness T1 of the first gripping part 12a1 is formed thin, and the thickness T2 of the second gripping part 12a2 is formed thicker than the thickness T1. That is, the first gripping part 12a1 is formed thin, and the second gripping part 12a2 is formed thick. In this way, when cleaning by gripping the second gripping part 12a2, increasing the thickness T2 of the second gripping part 12a2 makes it easier to grip deeply and increasing the strength of the second gripping part 12a2. can.

The storage battery 3 can be configured with, for example, a lithium ion battery with high energy efficiency. Further, the storage battery 3 is arranged below the second grip part 12a2 of the handle part 12. In this way, by providing the storage battery 3 at the rear end of the vacuum cleaner 100, the center of gravity of the handle part 12 becomes closer to the second grip part 12a2, so when using the vacuum cleaner 100 with the tip facing upward, the operation feeling is improved. can be made lighter.

The storage battery locking member 13 has a claw portion 13a formed on the free end side to be locked with the storage battery 3. Further, the storage battery locking 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 such that the claw portion 13a and the lower surface of the storage battery 3 are locked at 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 compared to a storage battery that is not removable. In addition, by preparing a spare storage battery 3 and a charging box that can charge the spare storage battery 3 as an option, when 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 in a store or the like.

FIG. 5 shows the exhaust port of the vacuum cleaner in a first state, (a) a side view, and (b) a sectional view taken along the line BB in (a).

As shown in FIG. 5(a), the vacuum cleaner 100 has an exhaust port 16 that discharges sucked air to the outside. The exhaust port 16 is arranged above the dust case 2 and in front of the first grip part 12a1. Further, the exhaust port 16 is configured by forming slit-shaped elongated holes 16a vertically aligned along the front-rear direction.

A louver (air path switching member) 16b is attached to the outer surface of the exhaust port 16 so as to cover the plurality of long holes 16a.

As shown in FIG. 5(b), the elongated hole 16a of the exhaust port 16 is formed in a substantially semicircular wall surface 16c in left and right directions. Five elongated holes 16a are formed on the left and right sides of the wall surface 16c. The louver 16b is slidably attached along the wall surface 16c. In FIG. 5(b), the louver 16b is located at the center, and parts of the left and right elongated holes 16a are exposed.

Further, the exhaust port 16 is formed to communicate with the motor case portion 11, and is configured such that the exhaust from the electric blower 40 cools the main body substrate 50 and then is discharged from the elongated hole 16a. When the louver 16b is in the state shown in FIGS. 5(a) and 5(b), air is exhausted from the left and right elongated holes 16a. Further, since the exhaust port 16 is located in front of the handle portion 12, the exhaust port 16 is easily located in front of the user, so that it is possible to reduce the amount of exhaust air hitting the user.

Moreover, a protrusion 16b1 that protrudes outward is formed on the surface of the louver 16b. As a result, when moving the louver 16b left and right, it becomes easy to hook a finger on the protrusion 16b1, making it easier to move the louver 16b left and right, and changing the direction of exhaust air quickly and easily. can.

FIG. 6 is a sectional view taken along the line BB in FIG.

As shown in FIG. 6, in the storage battery 3, six single cells 3a are arranged in a storage battery case 3b, with three cells arranged vertically and horizontally, respectively. Furthermore, in the three cells 3a in the upper row, the center cell 3a is arranged at a lower position than the left and right cells 3a, and a line connecting the centers of the cells 3a when the cells 3a are viewed from the axial direction. are arranged in a V-shape. Moreover, the three unit cells 3a in the lower row are similarly arranged in a V-shape. In this way, by orienting the axial direction of the unit cell 3a in the front-rear direction, the width of the storage battery 3 can be made narrower than when the axial direction of the unit cell 3a is oriented in the left-right direction. Further, by arranging the single cells 3a in two stages, upper and lower, and arranging the single cells 3a in a V-shape, the width of the storage battery 3 can be further narrowed. By narrowing the left and right widths in this way, it is possible to reduce contact between the storage battery 3 and the user during cleaning.

By arranging the cells 3a in a V-shape in this way, a recess 3c is formed on the upper surface of the storage battery case 3b. A hook slide portion 3d is formed in this recessed portion 3c. On the other hand, a rail portion 15 having a T-shape in cross section is formed on the main body portion 10 (below the handle portion 12) facing the hook slide portion 3d to slidably hold the hook slide portion 3d.

Further, locking portions 3e, 3e are formed at the lower end of the storage battery case 3b, to which claw portions 13a, 13a of the storage battery locking member 13 are locked. By forming the hook slide portion 3d in the dead space in this way, the space can be used effectively and the height of the storage battery 3 can be kept low.

FIG. 7 shows the exhaust port of the vacuum cleaner in a second state, (a) a side view, and (b) a sectional view taken along the line CC in (a).

As shown in FIG. 7A, the louver 16b of the vacuum cleaner 100 moves to the right (one side) along the wall surface 16c, and all the elongated holes 16a on the left side are open.

As shown in FIG. 7(b), all the long holes 16a on the right side are closed by the louver 16b, and all the long holes 16a on the left side are open. As a result, all the exhaust from the electric blower 40 is discharged from the left elongated hole 16a. Thereby, when the user grips the handle portion 12 with his left hand and places the vacuum cleaner 100 on the left side of the user, exhaust air can be prevented from hitting the user.

FIG. 8 shows the exhaust port of the vacuum cleaner in a third state, (a) a side view, and (b) a sectional view taken along the line DD in (a).

As shown in FIG. 8A, the louver 16b of the vacuum cleaner 100 moves to the left (other side) along the wall surface 16c, and all the elongated holes 16a on the left side are closed.

As shown in FIG. 8(b), all of the elongated holes 16a on the right side are opened by the louver 16b. As a result, all the exhaust from the electric blower 40 is discharged from the right elongated hole 16a. Thereby, when the user grips the handle portion 12 with his right hand and places the vacuum cleaner 100 on the right side of the user, exhaust air can be prevented from hitting the user.

In this way, in the exhaust port 16 of this embodiment, the left and right direction of the exhaust gas can be freely changed, so whether the user is right-handed or left-handed, the exhaust gas can be prevented from directly hitting the user.

In the vacuum cleaner 100 configured in this way, when the user operates the operation button 12b (see FIG. 3) provided on the handle portion 12 to start operation, the electric blower 40 (see FIG. 4) Power is supplied from a storage battery 3 (see FIG. 3). Then, the electric blower 40 is driven to suck in air. The sucked air flows into the dust case 2 through the inlet pipe 14 (see FIG. 2) and the inlet 2b (see FIG. 2). Then, the air containing dust that has flowed in becomes a swirling flow, centrifugal force acts on the dust, and the dust and air are separated. The air then passes through the filter 5, the electric blower 40, the main body board 50 (see FIG. 4), and is exhausted to the outside of the cleaner main body 1 through the exhaust port 16 (see FIG. 5(a)).

The pipe 81 is made of a lightweight material such as aluminum alloy from the viewpoint of design, and holds a relay terminal 82 midway in the axial direction. Further, the pipe 81 holds a second charging terminal 83 at the upper end in the axial direction. By making the pipe 81 made of metal, the charging stand 70 can be made to look slim in appearance, and a large mold is not required when manufacturing the extension member 80. Note that the pipe 81 is not limited to metal, and may be made of synthetic resin.

Further, in the pipe 81, a connecting portion 81s protruding downward from the relay terminal 82 is connected to a connecting holding portion 72c formed integrally with the stand portion 72. The connection holding part 72c is formed into an axially elongated cylindrical shape, and has an insertion hole 72c1 formed in the upper surface 72a into which the connection part 81s of the pipe 81 is inserted. This connection holding portion 72c is formed to have a length that can accommodate the entire connection portion 81s.

The relay terminal 82 is made of synthetic resin or the like, and includes a connecting terminal portion 82a that is connected to the first charging terminal 73, a holding member 82b that holds the connecting terminal portion 82a to the pipe 81, and an extension tube that holds the extension tube 300. It has a holding part 82c and an extension hose holding part 82d that holds an extension hose 800 (see FIG. 25).

The connecting terminal portion 82a is formed to protrude in a direction perpendicular to the axial direction of the pipe 81, and has a terminal portion connected to the first charging terminal 73 on the lower surface. Although not shown, this terminal section is configured similarly to the main body terminal section 17 shown in FIG. 14.

The holding member 82b includes a flange 82b1 extending toward the connecting terminal portion 82a, and a cylindrical body 82b2 that is formed upward from the flange 82b1 into a truncated cone shape in side view and is fixed to the pipe 81. There is.

In this way, the relay terminal 82 is configured such that when the pipe 81 is inserted and attached to the connection holding part 72c, the connection terminal part 82a and the first charging terminal 73 are connected and electrically connected. ing.

The extension tube holding portion 82c is formed on the front surface of the connecting terminal portion 82a, and has a pair of holding pieces 82c1, 82c1 that sandwich and hold the extension tube 300 (see FIG. 1(a)) from both left and right sides. The pair of holding pieces 82c1, 82c1 are configured to be flexible and deformable, and by pushing the extension tube 300 (see FIG. 1(a)) through the gap 82c2, the extension tube 300 can be held by the holding pieces 82c1, 82c1. .

The extension hose holding portion 82d is used when storing an extension hose 800 (see FIG. 25) to be described later, and includes a front holding piece 82d1 and a lower holding piece 82d2.

The front holding piece 82d1 is a plate-shaped piece that is held between the pipe 81 side and is formed on the upper surface of the connecting terminal portion 82a so as to protrude upward. Further, the tip (upper end) of the front holding piece 82d1 is bent toward the pipe 81 side.

The lower holding piece 82d2 supports the lower part of the extension hose 800, and has a lower support part 82d2 formed from the connecting terminal part 82a to the cylinder body 82b2. Further, the lower holding piece 82d2 connects the connecting terminal portion 82a and the holding member 82b to improve the strength of the relay terminal 82.

The second charging terminal 83 has the same configuration as the first charging terminal 73, and allows charging of the stick vacuum cleaner 100 (see FIG. 1(a)) in an upright position. Further, the second charging terminal 83 has a holding portion 83a held at the upper end of the pipe 81. A second charging terminal 83 is formed upward on the upper surface 83a1 of this holding portion 83a.

Furthermore, a restraining part 83b is formed on the front surface of the holding part 83a to receive the circumferential surface of the dust case 2 of the vacuum cleaner 100 and suppress the wobbling of the vacuum cleaner 100. The front surface of this restraining portion 83b is curved toward the front while expanding from side to side.

FIG. 16 is a side view showing a charging stand for a vacuum cleaner.

As shown in FIG. 16, in the charging stand 70, the pipe 81 is inserted into the connection holding part 72c from above with the connection terminal part 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) fits into the relay terminal 82, and the first charging terminal 73 (see FIG. 15) fits into the relay terminal 82. 1 charging terminal 73 and 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 part 72c and the position of the back surface (rear surface) of the extension member 80 substantially match. Further, the extending portion 71e is configured to protrude further rearward than the connecting holding portion 72c and the extension member 80 in the side view of FIG. 16.

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

FIG. 17 is a side view of the vacuum cleaner attached to the charging stand in a stick state. Note that 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 holding the handle part 12 and lowers the cleaner body 1 from above the second charging terminal 83 to connect the main body terminal part 17 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 vacuum cleaner 100's own weight.

Further, the dust case 2 is in contact with the restraining portion 83b, and the extension tube 300 is held by the extension tube 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. Thereby, even when charging in a state where the center of gravity of the vacuum cleaner 100 is high, the vacuum cleaner 100 can be stably held on the charging stand 70.

Further, when the vacuum cleaner 100 in a stick state is charged on the charging stand 70, the vacuum cleaner 100 is held in a posture tilted forward by an angle α with respect to the vertical direction (vertical direction). In this way, by holding the vacuum cleaner 100 in a forward leaning position, the center of gravity of the vacuum cleaner 100 is closer to the front than when the vacuum cleaner 100 is held upright, so that the vacuum cleaner 100 This will prevent you from falling backwards.

Note that 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 of the vacuum cleaner 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 in which the vacuum cleaner 100 in the stick state shown in FIG. 17 is charged, the extension member 80 is attached to the stand part 72 with the connection terminal part 82a facing backward (inversely). 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 about 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, resulting in the state shown in FIG. 18.

Then, the extension tube 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. In this way, in the charging stand 70 of this embodiment, the extension member 80 can be stored with the orientation changed, and the vacuum cleaner 100 can also be charged in a handy state. Further, since the extension member 80 does not need to be stored in a separate location from the charging stand 70, usability can be improved.

Note that the extension tube 300 can be stored by being held in the extension tube holding portion 82c of the extension member 80. In this way, the extension member 80 can be held in the extension tube holding part 82c of the charging stand 70, so when changing the vacuum cleaner 100 from the stick state to the handy state, the removed extension tube 300 can be extended. It can be quickly attached to the tube holding part 82c and stored. Further, when changing the vacuum cleaner 100 from the handy state to the stick state, the extension tube 300 can be removed from the extension tube holding portion 82c and quickly attached to the vacuum cleaner 100. Further, since the extension tube 300 can be held at a higher position than the floor surface, it is easy for the user to attach and detach, and the usability can be improved. Further, since there is no need to store the extension tube 300 in a separate location 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 part 17 is fitted to the first charging terminal 73, the main body terminal 17d contacts the terminal 73c, and the edge 17f of the main body terminal 17d further descends, so that the terminal 73c Deforms by bending backwards. Since the terminal 73c has a spring force that biases it forward, the main body terminal 17d and the terminal 73c maintain contact with each other while the vacuum cleaner main body 1 is attached to the charging stand 70. , charging of the storage battery 3 (see FIG. 3) continues.

In addition, since the first charging terminal 73 is fitted with the main body terminal portion 17 in a concave-convex manner, even if the user touches the vacuum cleaner main body 1 during charging, for example, the electrical continuity between the main body terminal 17d and the terminal 73c is maintained. (contact state) is never released. Furthermore, even when the second charging terminal 83 (see FIG. 16) is connected to the main body terminal part 17, even if the user touches the vacuum cleaner main body 1 during charging, the electrical continuity between the main body terminal 17d and the terminal 73c is maintained. (contact state) is never released.

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

Furthermore, in the charging stand 70, a 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 high position from the floor surface, it is difficult for dust to accumulate on the first charging terminal 73, and it is also possible to reduce the possibility that dust comes up from the floor surface and adheres thereto. Further, in the charging stand 70, a 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 high position from the floor surface, it becomes difficult for dust to accumulate on the second charging terminal 83, and it is also possible to reduce the possibility that dust rises from the floor surface and adheres thereto.

In addition, in the vacuum cleaner 100 set on the charging stand 70, the first charging terminal 73 and the second charging terminal 83 are located near the center of gravity of the vacuum cleaner 100 (the position of the electric blower 40 and the storage battery 3). Since the first charging terminal 73 and the second charging terminal 83 receive the vicinity of the center of gravity, 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, charging can be performed with the dust case 2 removed, so that charging can be performed even while the dust case 2 is being washed and dried.

Further, when the vacuum cleaner 100 is placed in a handy state on the charging stand 70 for charging, 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. Thereby, the dead weight of the vacuum cleaner 100 can be applied intensively to the first charging terminal 73, so that the main body terminal portion 17 and the first charging terminal 73 can be reliably connected.

Although not shown, when charging the vacuum cleaner 100 in a stick state, the main body terminal portion 17 of the vacuum cleaner 100 and the second charging terminal 83 are connected by a mechanism similar to that shown in FIG. 19. Ru. Therefore, even when the main body terminal section 17 and the second charging terminal 83 are connected, the same effect as when the first charging terminal 73 and the main body terminal section 17 are connected can be obtained.

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

FIG. 20 is a usage diagram when cleaning a floor surface with a stick vacuum cleaner.

As shown in FIG. 20, when the vacuum cleaner 100 is in a stick state and the vacuum cleaner 100 is pushed out in front of the user to clean the floor, the user can use the second grip part of the handle part 12 to clean the floor. While holding 12a2, move the vacuum cleaner 100 back and forth. Although not shown, when cleaning the floor with the vacuum cleaner 100 positioned beside the user, the user holds the first grip part 12a1 of the handle part 12 while using the electric vacuum cleaner 100. Move the vacuum cleaner 100 back and forth. In this manner, when the user cleans the floor surface, he or she can change the position of the handle portion 12 and clean the floor surface.

FIG. 21 is a usage diagram when cleaning a high place with a stick vacuum cleaner.

By the way, in a vacuum cleaner whose center of gravity is on the tip side when it is in a stick state (see Patent Document 1), when cleaning the vacuum cleaner 100 in a place higher than the floor, the user has to move the vacuum cleaner 100. Since you have to lift the tip upwards, it puts strain on your wrists.

Therefore, as shown in FIG. 21, since the electric blower 40 (see FIG. 4) and the storage battery 3, which are heavy items of the vacuum cleaner 100, are located close to the handle part 12 (close to your hand), the vacuum cleaner 100 The center of gravity G becomes closer to the user's hand. Thereby, even when the vacuum cleaner 100 is in a stick state and the vacuum cleaner 100 is used to clean a place higher than the floor surface, it becomes easier to clean, and usability can be improved. In FIG. 21, the case of cleaning stairs has been described as an example, but it is also effective when lifting the vacuum cleaner 100 to clean an air conditioner panel or the like.

Next, various applied suction bodies connected to the vacuum cleaner 100 will be explained. The above-mentioned vacuum cleaner 100 can be connected to various types of suction suction bodies as accessories and replaced to perform cleaning.

FIG. 22 is a cross-sectional view showing a standard mouthpiece with an opening/closing member attached, in which (a) is when moving forward, (b) is when it hits a wall, and (c) is when moving backward. Note that in FIG. 22, illustration of the motor that drives the rotating brush and the board that controls the rotating brush are omitted.

As shown in FIG. 22(a), the standard suction port 400 includes a suction case 401, a first brush 402 driven by a motor (not shown), and a second brush 403 rotated by friction with the floor surface. It is configured with

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

Furthermore, 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 includes a protrusion 404b extending perpendicularly to the axial direction of the rotation shaft 404a, and an opening/closing body 404c extending from the rotation shaft 404a in a direction opposite to the protrusion 404b. The protrusion 404b is made of a hard plate-like member. The opening/closing body 404c includes a brush portion 404c1 on the front side and a rubber plate 404c2 on the rear side, stacked one on top of the other.

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

As shown in FIG. 22(b), when the standard suction port 400 hits a wall, the tip (upper end) of the projection 404b hits the wall first. 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 moves forward. By moving the opening/closing body 404c forward, the opening 401a at the lower front of the mouthpiece case 401 is closed. With this configuration, dust near the wall (corner) can be sucked in and removed. Moreover, 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, so that the opening/closing body 404c moves forward. works. This increases the static pressure within the suction case 401, making it possible to reliably suck in dust.

Furthermore, the cordless vacuum cleaner 100 has weaker suction power than a vacuum cleaner that is powered by a household outlet. Therefore, when the standard suction port 400 is moved forward (see FIG. 22(a)), the front surface (opening 401a) of the suction case 401 is opened, so the operating force can be reduced and large particles can be sucked out. can. Further, when the vehicle moves backward (see FIG. 22(c)), the opening/closing member 404 closes and the static pressure increases, so that, for example, sand and dirt in the carpet can be firmly sucked in. In addition, by configuring the standard suction port 400 to be smaller than the suction port connected to a 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 becomes easier to spread.

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-shaped mouthpiece.

As shown in FIG. 23(a), the crevice suction port 500 is for sucking up dirt accumulated between furniture or in the 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 its base end, and has a narrow suction port 502 directed toward an object to be sucked at its distal end.

As shown in FIG. 23(b), the small suction port (mini power head) 600 is a substantially smaller version of the standard suction port 400 described above, and is suitable for cleaning the same area as the standard suction port 400. Can be applied to places with physical resistance (sofas, bedding, etc.).

Further, the small-sized suction port 600 includes a suction case 601 that is narrower than the standard suction port 400, and a rotating brush 602 that is rotated by a motor 606 (see FIG. 24(a)). Further, the small suction port 600 includes a connection port 604 having a terminal electrically connected to the vacuum cleaner 100.

FIG. 23(c) shows a broom-shaped suction port 700 for cleaning the rail of a sash, the inside of a drawer in which small items are stored, etc. The broom-shaped suction port 700 has a front part (broom part) 700a having a brush body 701 for sweeping away dirt, a tube 702 made of a flexible material such as rubber or elastomer for sucking dirt, and a vacuum cleaner 100. It consists of a rear part (joint part) 700b having a connecting part 703 connected to the rear part (joint part) 700b. The connecting part 703 of the rear part 700b fits into the introduction pipe 14 of the vacuum cleaner 100 shown in FIG. . At this time, the contact portion 14a and the contact portion cover 705 are in contact with each other without a gap, thereby suppressing dirt and the like from entering the contact portion 14a.

The front part 700a and the rear part 700b are connected by a joint part 704, and the direction of the front part 700a having the brush body 701 and the tube 702 can be changed. The front portion 700a can rotate 360 degrees from the fixed rear portion 700b. In other words, it has a rear portion 700b that is rotatably connected to the front portion 700a. FIG. 37(a) is a side view of FIG. 23(c), and FIG. 37(b) is a state in which the front portion 700a of FIG. 37(a) is rotated by 180 degrees. The broom-shaped suction port 700 is connected to the vacuum cleaner 100, the extension pipe 300, or the extension hose 800, and the connection part 703 is fixed by the release button 18. The line XX shown in FIG. 37 is the center line of the rear part 700b, and is horizontal to the front-rear direction of the arrow shown in the figure. Further, the YY line shown in FIG. 37 is the center line of the front portion 700a. The angle θ formed by the line XX and the line YY changes when the front portion 700a is rotated, and rotates within a range of 15 degrees to 50 degrees. In this embodiment, the front part 700a can be turned further downward by turning from a state facing downward by 15 degrees or more from the front-rear direction; however, the front part 700a is not limited to this, and the front part 700a may be turned downward from a substantially horizontal direction. It's okay. This broom-shaped suction port 700 is designed for cleaning by pulling from the front to the rear, and the brush body 701 and tube 702 are always facing downward when viewed from the front and rear directions within the movable range. Easy to clean.

In the aforementioned front portion 700a, a brush body 701 is arranged around a plurality of tubes 702. . In this embodiment, the tubes 702 are arranged in two rows in the vertical direction of the arrow in FIG. 23(c) and in three rows in the horizontal direction, for a total of six tubes. The brush body 701 is approximately 5 mm longer in front than the tip of the tube 702. If the brush body 701 is shorter than the tip of the tube 702, the tube 702 may rub the surface to be cleaned, and a flexible material such as a rubber material or an elastomer may adhere to the surface to be cleaned. Furthermore, if the brush body 701 is longer than the tip of the tube 702, the tip of the tube 702 will be far away from the cleaning surface while the brush body 701 is in contact with the cleaning surface, and the suction force will be weakened. Therefore, the distance between the brush body 701 and the tip of the tube 702 is preferably about 3 to 5 mm, and the brush body 701 is preferably 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-shaped mouthpiece 700. Furthermore, 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 is small enough to prevent small objects from being sucked in, and in this embodiment has a substantially cylindrical shape with openings at both ends of approximately 8 mm, and is in fluid communication with the vacuum cleaner 100, with the front portion 700a extending from the tube end 710. Only suck air. Although the tube 702 has a substantially cylindrical shape, it 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 appears approximately S-shaped from view A. In other words, the tube end 710 is not coplanar and has a recess. The wave-shaped portion 720 has a shape in which circular arcs each having a diameter of about 5 mm are connected. For example, if the tube end is cut diagonally, if the tube end is brought close to the cleaning surface at the same angle as the cut angle, it may stick to the cleaning surface. However, by providing the corrugated portion 720 on the tube end 710 as in this embodiment, a gap is always created when the tube comes into contact with the cleaning surface, and it is possible to suppress the tube from 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 view B, so that an additional gap can be provided. In this embodiment, the corrugated portion 720 is approximately 5 mm in length, but this is not the case since the corrugated portion 720 varies depending on the diameter of the tube 702.
Further, as described above, in this embodiment, six tubes 702 are provided, and each tube is designated 702a to 702f. The tube 702a has the concave portion 730 approximately on the front side and the convex portion 740 approximately on the back side when viewed from B view, and the tube 702c has the concave portion 730 approximately on the back side and the convex portion 740 on the approximately front side when viewed from B view. becomes. In the tube 702b, when viewed from view A, the concave portion 730 is located approximately on the back side, and the convex portion 740 is located approximately on the near side. 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, when viewed from view A, the concave portion 730 is located approximately on the front side, and the convex portion 740 is located approximately on the back side. That is, in the plurality of tubes 702, there are combinations in which the recessed portions of the edges do not face the same direction with respect to the central axis of each tube. Thereby, since there are combinations in which 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 a corner, and a decrease in suction force can be suppressed.

By configuring the tube end 720 in such a shape, it does not stick to the surface to be cleaned as described above, prevents small items such as coins from sticking, and prevents the sash rails and drawers containing small items from sticking. Easy to clean.

FIG. 24(a) shows an external view of the small mouthpiece viewed from below, and FIG. 24(b) is a sectional view taken along the line MM shown in FIG. 24(a).

As shown in FIGS. 24(a) and 24(b), the external appearance of the small suction mouthpiece 600 is composed of a mouthpiece cover 601, a lower case 602, a rotating brush 603, and a joint part 604. The lower case 602 houses the rotating brush 603. A safety switch 605 that stops the rotation of the rotating brush 603 when the small suction port 600 is lifted, and a motor 606, a board (not shown), etc. are housed inside.

The rotating brush 603 has brushes planted on the outer periphery of a core member provided at the center of the shaft, and is removably supported by the shaft, although the structure is omitted. Therefore, tangles such as hair can be easily removed, and the rotary brush 603 can be kept clean as it can be washed with water.

The suction chamber 602a that accommodates the rotating brush 603 is a substantially semicircular space that follows the shape of the rotating brush 603, and has an opening at approximately the center of the partition wall forming the suction chamber 602a. The section is in fluid communication with the fitting section 604. The inlet side (front side) of the joint part 604 is provided with a joint part inlet port 604a formed concentrically so as to offset the partition wall forming the suction chamber 602a of the lower case 602. Therefore, the joint inlet 604a can freely rotate 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 movable within a movable range coaxially with the rotating brush 603. Furthermore, within the movable range, the joint inlet 604a communicates with the opening of the suction chamber 602a. The small mouthpiece 600 shown in FIG. 23(b) is in a state where the joint part 604 is rotated to the rearmost position, and the MM cross-sectional view of the small mouthpiece 600 shown in FIG. 24(b) shows the joint part 604 in the most forward position. It is in a rotated state.

As described above, the motor 606 and the safety switch 605 are provided behind the suction chamber 602a. Further, the joint portion 604 has a front joint portion inlet 604a that is rotatably movable. Therefore, since the rotation axis of the joint part 604 is in front of the small suction port 600 and the heavy motor 606 etc. is located at the rear, when the small suction port 600 is lifted, the rotation axis of the joint part 604 is the center, and the small suction port 600 is rearward. moves downward under its own weight.

In this way, when the small suction spout 600 is lifted up, the rear of the small suction spout 600 moves downward under its own weight around the rotation axis of the joint part 604, so that the bottom surface of the small suction spout 600 follows the unevenness of the sofa or bedding. The safety switch 605 can be cleaned without being activated easily.

Furthermore, when the small suction port 600 is lifted, large granular dust (for example, rice grains, etc.) may be thrown backwards and scattered by the rotation of the rotating brush 603 until the rotating brush 603 stops. Even if particulate dust is repelled by the rear part of the small suction port 600 moving downward under its own weight, it collides with the lower case 602, so that scattering can be suppressed.

FIG. 25 is a perspective view of the extension hose.

As shown in FIG. 25, the extension hose 800 has a suction port 802 with a handle 801 at its tip, a connection port 803 connected to the vacuum cleaner body 1 (see FIG. 2) at its base end, and a connection port 802 connected to the suction port 802. A bellows tube 804 that connects to the opening 803 is configured.

Further, an electric wire (not shown) is passed through the inside of the extension hose 800, and a small suction port 600 (see FIG. 24(a)) provided with a rotating brush 602 operated by a motor 606 is configured to be connectable. .

By connecting such an extension hose 800 to the vacuum cleaner body 1 and using it, you can freely position the small suction port 600 while holding the vacuum cleaner body 1 with one hand and the handle 801 with the other hand. You can clean it while changing it. This makes it easier to clean the seats, feet, etc. inside the car compared to a vacuum cleaner without an extension hose.

FIG. 26(a) is a front view showing a state in which various applied suction bodies including an extension hose are attached, and FIG. 26(b) is a side view showing a state in which various applied suction bodies other than the extension hose are attached.

As shown in FIGS. 26(a) and 26(b), a gap suction port 500, a small suction port 600, a broom-shaped suction port 700, and an extension hose 800 can be attached to the charging stand 70. That is, the gap mouthpiece 500 can be attached and stored in the side storage part 71d (see FIG. 9), the small size mouthpiece 600 can be attached and stored in the extension part 71e, and the broom-shaped mouthpiece 700 can be stored in the side storage part 71c. Configured to be installed and stored. Note that the positions of the gap suction port 500, the small suction port 600, and the broom-shaped suction port 700 are not limited to those in this embodiment, and can be changed as appropriate.

Further, the charging stand 70 can hold the extension hose 800 with the longitudinal center of the bellows tube 804 sandwiched between the front holding piece 82d1 and the pipe 81.

In this way, the charging stand 70 can store various types of applied suction bodies such as the gap suction spout 500, the small suction spout 600, the broom-shaped suction spout 700, and the extension hose 800. As a result, the gap suction port 500, the small suction port 600, the broom-shaped suction port 700, and the extension hose 800 can be quickly replaced and used without storing them in another place in the room, improving usability.

FIG. 27 shows how the extension hose is used, in which (a) shows a vacuum cleaner equipped with the handle of this embodiment, and (b) shows a vacuum cleaner equipped with a handle of a comparative example.

The vacuum cleaner shown in FIG. 27(b) includes a handle portion 120 on the vacuum cleaner body 1. The handle portion 120 has a structure in which the first grip portion 12a1 is not provided in the handle portion 12 of this embodiment. When the extension hose 810 is connected to the vacuum cleaner main body 1 having such a handle portion 120, the tip of the vacuum cleaner main body 1 faces downward. Therefore, as shown in FIG. 27(b), the length L10 of the extension hose 810 becomes longer.

On the other hand, the vacuum cleaner 100 of this embodiment shown in FIG. 27(a) includes a handle portion 12 provided with a first grip portion 12a1 in addition to a second grip portion 12a2. Therefore, when the extension hose 800 is connected to the vacuum cleaner main body 1, the user holds the first grip portion 12a1 so that the tip of the vacuum cleaner main body 1 faces forward. Therefore, as shown in FIG. 27(a), the length L1 of the extension hose 800 can be configured to be shorter than in the case of FIG. 27(b).

FIG. 28 shows a gap suction port according to a modified example, in which (a) is a perspective view, (b) is a plan view, and (c) is a side view.

Further, the light guide 504a has a peripheral wall 504s and a front wall 504t, and is formed into a substantially square column shape. Furthermore, a linear slide groove 504e, which is hooked onto the guide rail 503a, is formed on the upper surface of the light guide 504a. Further, a valve element 504f for a suction valve, which can adjust the amount of air taken in, is formed protruding from the top surface of the tip of the light guide 504a. The valve body 504f is formed to be elongated in the axial direction.

The axial length L30 of the slide groove 504e is longer than the axial length L40 of the guide rail 503a.

FIG. 30 is a cross-sectional view taken along the line EE in FIG. 28(b).

As shown in FIG. 30, the guide rail 503a is formed in an inverted T shape when viewed from the axial direction.

A cavity 504g communicating with the slide groove 504e is formed inside the light guide 504a. This cavity 504g is formed into a substantially rectangular shape in cross-sectional view, and has a width W that allows the guide rail 503a to slide, a height H that allows the guide rail 503a, the LED 504b, and the storage battery 504c (see FIG. 29) to be accommodated. have.

In this way, the suction valve V is configured by the elongated hole 503c and the valve body 504f. By providing the suction valve V, the amount of air taken into the vacuum cleaner 100 from the outside can be varied. This makes it possible to attach the gap suction port 500A even to vacuum cleaners with different suction powers, thereby increasing versatility.

When assembling the gap suction port 500A configured in this way, the slide groove 504e of the light guide 504a is inserted into the guide rail 503a from the front and slid backward. Then, the LED 504b and the storage battery 504c are inserted into the light guide 504a, and the rear end of the light guide 504a is closed with the lid 504d. By attaching the cover member 505 to the mouthpiece main body 503, it is possible to prevent the light guide member 504 from falling off from the mouthpiece main body 503. Note that the lid 504d is provided with a mechanism for turning on/off the LED 504b.

Then, the gap suction port 500A is attached to the vacuum cleaner 100, and the extension pipe 300 to which the gap suction port 500A is attached is attached to the vacuum cleaner main body 1. Then, by turning on the power of the LED 504b, the LED 504b emits light. The emitted light propagates forward while passing through the peripheral wall 504s (see FIGS. 29 and 31) of the light guide 504a, and is directly irradiated onto the front wall 504t (see FIGS. 29 and 31) at the front end. This makes it possible to efficiently illuminate the space in front of the back (gap), making it easier to remove dust.

FIG. 33 is a side view showing a state in which a gap suction port according to another modification is attached to a vacuum cleaner, and FIG. 34 is a sectional view taken along the line HH in FIG. 33.
