FIG. 1A is a perspective view showing a state in which the vacuum cleaner of the present embodiment is stored in a charging stand in a stick state.
The vacuum cleaner 100 can be changed to various usage states such as a handy state and a stick state for cleaning. The charging stand 70a in which the vacuum cleaner 100 is stored accommodates the vacuum cleaner 100 in a stick state, and includes a base member 71, a stand member 72, and a holder member 73. The output plug 81 of the AC adapter 80 for charging the storage battery 3 mounted on the vacuum cleaner 100 is attached to the holder member 73, and when the vacuum cleaner 100 is set on the charging stand 70a, the output plug 81 is connected to the input jack 17b of the vacuum cleaner 100 so that it can be charged. By doing so, it is possible to configure the charging stand itself without providing any electric parts, and it is possible to reduce the cost and improve the productivity. Further, since there is no change in the electrical connection with or without the stand member 72, the reliability of the product can be ensured.

The base member 71 has a mounting surface 71a and an extending portion 71b. The mounting surface 71a is a substantially rectangular plate-shaped portion. The extending portion 71b is a substantially truncated cone-shaped portion. The extending portion 71b is provided so as to be substantially perpendicular to the mounting surface 71a. The central axis of the extending portion 71b is provided so as to be located substantially at the center of the mounting surface 71a in the short side direction and about 3/4 in the long side direction.

Further, FIG. 1B is a perspective view showing a state in which the vacuum cleaner of the present embodiment is stored in the charging stand in a handy state. The charging stand 70b in this state houses the vacuum cleaner 100 in a handy state, and unlike the charging stand 70a, the charging stand 70b omits the stand member 72 and includes only the base member 71 and the holder member 73.

FIG. 2 is an exploded view of the vacuum cleaner of the present embodiment.
As shown in FIG. 2, the vacuum cleaner 100 includes a vacuum cleaner main body 1, a dust case 2 (dust collector), a storage battery 3 (storage device), and an airtight holding member 90.

The vacuum cleaner main body 1 includes a main body portion 10, a motor case portion 11, and a handle portion 12.

The main body 10 is formed with a connection port 10a (suction port) to which an extension pipe 300 (see FIG. 1) and a standard suction port 400 (see FIG. 1) are connected. The connection port 10a is made of the same resin as the main body portion 10, the motor case portion 11, the handle portion 12, and the like. Further, the connection port 10a has a substantially circular opening and is formed so as to face forward. Further, as accessories, a gap / brush switching nozzle 110, an extension tube 300, a standard suction port 400, a small suction port 600, a broom type suction port 700, etc. (hereinafter, may be collectively referred to as an attachment) are connected to the connection port 10a. You can do it.

Further, the main body 10 is provided with an introduction pipe 14 (see FIG. 3) in which the dust case 2 is detachably attached and air including dust sucked from the connection port 10a is sent to the dust case 2.

The motor case portion 11 includes an electric blower 40 (see FIG. 6) and a main body substrate 50 (see FIG. 6). Further, on the front surface of the motor case portion 11, a circular suction port 11a is formed in which clean air collected by the dust case 2 is sucked. Further, on the front surface of the motor case portion 11, a main body terminal portion 17 connected to the charging stand 70 is provided below the suction port 11a.

The handle portion 12 is provided on the rear side of the main body portion 10 and has a grip portion 12a formed in a substantially L shape. The grip portion 12a has a first grip portion 12a1 extending linearly in the front-rear direction and a second grip portion 12a2 extending linearly in the substantially vertical direction. The first grip portion 12a1 is located above and in front of the second grip portion 12a2. The second grip portion 12a2 is slightly inclined so that the upper portion faces forward with respect to the vertical direction. Further, the first grip portion 12a1 and the second grip portion 12a2 are formed in a substantially rod shape and continuously. As described above, by forming both the first grip portion 12a1 and the second grip portion 12a2 in a linear shape, the user can easily recognize the position of the handle. Further, since the first grip portion 12a1 and the second grip portion 12a2 are connected so as to bend at an angle close to a right angle, the hand shifts to the second grip portion 12a2 when gripping the first grip portion 12a1. On the contrary, when the second grip portion 12a2 is gripped, it is difficult for the hand to slip to the first grip portion 12a1.

Further, the handle portion 12 is provided with a lock member 13 for locking the storage battery 3. The lock member 13 is formed in a button shape and is supported so as to be swingable.

The tubular body 91 has an elastic portion 91a formed in an annular shape with a soft resin on the tip end side. The tubular body 91 is formed of a material harder than the elastic portion 91a on the base end side, and has a connecting portion 91b that can be connected to the main body portion 10. The tubular body 91 is formed by integrally forming two different members of the elastic portion 91a and the connecting portion 91b. The elastic portion 91a is made of a material that is elastically deformable (flexible and deformable) such as an elastomer. By attaching such an airtightness holding member 90 to the connection port 10a of the vacuum cleaner main body 1, the entire tip 90s of the airtightness holding member 90 can be brought into close contact with the floor surface, and the suction force is improved as compared with the case where the airtightness holding member 90 is not brought into close contact. Can be made to. Further, by forming the connecting portion 91b with a hard one, the airtight holding member 90 can be attached to the main body portion 10 in a stable state without falling off.

In the present embodiment, the case where the elastic portion 91a is formed of an elastic material such as an elastomer has been described as an example, but the present invention is not limited to this. For example, substantially the entire tubular body 91 may be formed of the same material as the connecting portion 91b, and short hairs electrostatically planted at the tip of the tubular body 91 may be provided in an annular shape. Even with such an electrostatic flocking, the tip of the airtightness holding member 90 can be brought into close contact with the floor surface as in the elastomer, and the suction force can be improved.

A vertically elongated fitting groove 10b is formed on the outer surface of the connection port 10a of the main body 10. One fitting groove 10b is formed on each of the left and right sides. At the base end of the connecting portion 91b, a protrusion (not shown) is formed which is concavely fitted and locked with the fitting groove 10b.

Further, the main body 10 is provided with a light emitting element 10c (see FIG. 2) above the connection port 10a. The light emitting element 10c is configured to emit light toward the front, that is, the surface to be cleaned (floor surface or the like). Further, the tip surface 10c1 of the light emitting element 10c is located on substantially the same surface as the tip 10a1 of the connection port 10a.

The storage battery 3 supplies electric power to an electric blower 40 (see FIG. 6) and the like, and is composed of a secondary battery such as lithium ion and nickel hydrogen. Further, the storage battery 3 has a substantially semi-cylindrical case 3a made of synthetic resin, and can be attached to and detached from the main body 10 by sliding the case 3a in the front-rear direction.

A terminal portion 3b connected to the main body portion 10 is provided on the upper surface of the case 3a. Further, on the upper surface of the case 3a, a slide groove 3c that is slidably supported by the main body 10 is formed in front of the terminal portion 3b. Further, on the upper surface of the case 3a, behind the terminal portion 3b, slide rails 3d and 3d slidably supported by the main body portion 10 are formed so as to project to the left and right sides.

Further, on the front surface of the case 3a, an introduction hole 3e into which cooling air for cooling the storage battery 3 is introduced is formed on one side (left side) in the left-right direction (width direction). The introduction hole 3e is formed elongated in the vertical direction.

Further, on the front surface of the case 3a, a discharge hole 3f is formed on the other side (right side) in the left-right direction (width direction) to discharge the air after cooling the storage battery 3. The discharge hole 3f is formed so as to have a symmetrical shape with the introduction hole 3e described above.

Further, on the back surface of the case 3a, a lock recess 3g is formed in which the lock member 13 is fitted and locked to the main body 10.

FIG. 3 is an arrow view in the X direction of FIG.
As shown in FIG. 3, the dust case 2 is of a cyclone type, and has a function of separating air including dust sucked from the introduction pipe 14 into dust and air and collecting the dust. Further, the dust case 2 is arranged in front of the motor case portion 11 with the axial direction in the front-rear direction, and has a substantially cylindrical accommodating portion 2a. Further, a substantially rectangular inflow port 2b (see FIG. 2) connected to the introduction pipe 14 is formed on the upper surface (side surface) of the dust case 2. The air containing dust that has flowed into the inflow port 2b becomes a swirling flow, centrifugal force acts on the dust, and after being separated into dust and air in the dust case 2, the air from which the dust is separated is the dust case. It is discharged from the rear part (back surface) of 2.

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 for unlocking the lid 2c is provided on the upper portion of the lid 2c. The internal mechanism of the dust case 2 can be configured based on JP-A-2016-137165.

An exhaust port 16 is provided at the bottom of the motor case portion 11. The exhaust port 16 has a plurality of slits 16a along the front-rear direction, and the plurality of slits 16a are formed side by side in the vertical direction. Although not shown, the exhaust ports 16 are provided on both the left and right sides.

FIG. 4 is a perspective view of the vacuum cleaner of the present embodiment.
As shown in FIG. 4, in the vacuum cleaner 100, the dust case 2 is attached below the main body 10 and in front of the motor case 11. In this case, when the dust case 2 is attached to the vacuum cleaner main body 1, the lid lock mechanism 2e is hidden on the vacuum cleaner main body 1 side. This is because if the lid lock mechanism 2e is provided on the opposite side (outside), the lid lock mechanism 2e may be released during cleaning, but the lid lock mechanism 2e is hidden behind the vacuum cleaner body 1. This is because malfunction can be prevented. For example, when cleaning under a sofa or a bed in a stick state, the vacuum cleaner main body 1 may be brought closer to the floor surface horizontally. At this time, if the lid lock mechanism 2e is provided on the front side, the lid lock mechanism 2e may be released in contact with the floor surface. The positions of the lid lock mechanism 2e and the hinge portion 2d are not limited to this, and may be provided on the left and right sides of the vacuum cleaner main body 1.

In addition, the dust case 2 is provided with a care brush 2s (see FIGS. 2 and 3) that can be attached and detached. The 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 vacuum cleaner main body 1. Therefore, it is difficult to remove the cleaning brush 2s during operation, and it is not necessary to store the cleaning brush 2s in a place different from the vacuum cleaner 100.

Further, when the airtightness holding member 90 is attached to the vacuum cleaner main body 1, the light emitting element 10c is covered by the airtightness holding member 90. In other words, the inner diameter of the airtightness holding member 90 is set so that the light emitting element 10c is located inside the airtightness holding member 9.

FIG. 5 is a plan view of the vacuum cleaner of the present embodiment.
As shown in FIG. 5, the connecting portions 91b of the airtightness holding member 90 are formed with extending portions 91b1 and 91b1 extending rearward on both the left and right sides. A concave portion 91b2 is formed between the extension portion 91b1 on the left side and the extension portion 91b1 on the right side in a plan view. The concave portion 91b2 fits with the front end portion 10d1 of the protruding portion 10d formed on the upper surface of the tip of the main body portion 10. As a result, the airtightness holding member 90 is positioned in the front-rear direction and the left-right direction with respect to the connection port 10a (see FIG. 2).

The introduction pipe 14 formed in the main body 10 is formed so as to extend diagonally rearward to the right and then downward, and is connected to the inflow port 2b (see FIG. 2) of the dust case 2. As a result, a swirling flow can be generated in the accommodating portion 2a of the dust case 2, and dust can be effectively separated by centrifugal force.

The width of each of the dust case 2 and the storage battery 3 is formed to be slightly shorter than the width W of the main body 10. In other words, the dust case 2 and the storage battery 3 are configured so as not to protrude from the side of the main body 10. As a result, the vacuum cleaner 100 can be smoothly moved in the front-rear direction regardless of whether the user holds it with either the left or right hand for cleaning, and the usability can be improved.

FIG. 6 is a sectional view taken along line VI-VI of FIG. Note that FIG. 6 shows a state in which the airtightness holding member 90 is removed from the vacuum cleaner 100.
As shown in FIG. 6, the electric blower 40 is housed in the motor case portion 11 of the main body portion 10. Further, 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 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. Further, a part of the air that has cooled the main body substrate 50 is designed to cool the storage battery 3.

The main board 50 has an upper board 50a and a lower board 50b which are divided into upper and lower parts and arranged in two stages, and various parts are mainly placed on opposite surfaces (lower surface of the upper board 50a and upper surface of the lower board 50b). It is implemented. 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 of the main body substrate 50. Further, the main body substrate 50 is covered with a flame-retardant resin case 51, and the wind (air) discharged from the electric blower 40 flows in the resin case 51 from the rear side to the front side, and the resin. It flows to the storage battery 3 side through the lower side of the bottom surface of the case 51.

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, in the electric blower 40, the motor case portion 11 is formed so as to bulge toward the handle portion 12, so that the dimension of the main body portion 10 in the front-rear direction (total length) 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 electric cleaning is performed. The machine 100 can be held stably.

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. it 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 gripped stably.

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. it 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, so that when the tip of the vacuum cleaner 100 is used upward, a feeling of operation is felt. Can be lightened.

The lock member 13 has a button-type operation portion 13a formed at the rear end portion. The operating portion 13a has an arm portion 13b extending forward, and the front end of the arm portion 13b is supported by the main body portion 10. Further, the arm portion 13b is urged downward by the spring 13c. As a result, when the lock member 13 is fitted into the lock recess 3g and locked, the operating portion 13a is prevented from coming out of the lock recess 3g. Further, when the storage battery 3 is removed from the main body 10, the operation portion 13a can be pulled out from the lock recess 3g while repelling the urging force of the spring 13 by pressing the operation portion 13a.

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 capable of charging 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 replaced with the spare storage battery 3. It is possible to extend the cleaning time. With such a configuration, it is effective when cleaning a wide floor surface such as a store, for example.

As shown in FIG. 6, when the surface passing through the tip surface of the connection port 10a of the main body 10 is R1, the tip 2f of the dust case 2 and the surface R1 (the surface extending in the vertical direction with respect to the paper surface) are approximately abbreviated. It is configured to be flush. The tip 2f of the dust case 2 does not protrude forward from the surface R1. As a result, even when cleaning the vacuum cleaner body 1 without attaching the airtightness holding member 90, the tip of the connection port 10a can be cleaned while being in contact with a hard floor surface such as flooring.

In the dust case 2, the filter 5 is housed at the rear end in the axial direction of the housing part 2a. The filter 5 is formed by folding it into 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 is composed of, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The HEPA filter is an air filter having a particle collection rate of 99.97% or more and an initial pressure loss of 245 Pa or less with respect to particles having a rated air volume and a particle size of 0.3 μm.

It is an exploded view of each. The connecting portion between the base member 71 and the stand member 72 and the connecting portion between the stand member 72 and the holder member 73 have the same shape and are recombinable. That is, the shape of the base protrusion shape portion 71c of the base member 71 and the stand protrusion shape portion 72b of the stand member 72, which will be described later, are the same, and the concave shape portion 72h of the stand member 72 and the concave shape of the holder member 73. The shape of the portion 73h is the same.

The base member 71 has a substantially rectangular mounting surface 71a on which the standard suction port 400 (see FIG. 1) is mounted. Further, the base member 71 has an extending portion 71b extending upward at approximately the center in the width direction (left-right direction) and approximately 3/4 in the length direction (front-rear direction). At the tip of the extending portion 71b, a base protrusion shaped portion 71c to which the stand member 72 or the holder member 73 can be selectively attached is provided. Further, the base member 71 is provided with a weight 75 (not shown) inside, so that the charging stand 70 is less likely to fall when the vacuum cleaner 100 is attached to the charging stand 70.

The stand member 72 has a substantially tubular shape, and the lower end portion is a concave portion 72h that fits with the base protrusion shape 71c of the base member 71. Further, the upper end portion is provided with a stand protrusion shape portion 72b to which the holder member 73 can be attached, which is the same as the shape of the base protrusion shape portion 71c provided at the upper end of the base member 71.

By connecting and connecting the stand member 72, the holder member 73, and the base member 71 configured in this way, as shown in FIG. 7, the base member 71, the stand member 72, and the holder member 73 become continuous surfaces. , A charging stand 70 having a good appearance can be obtained.
Further, by connecting and connecting the holder member 73 and the base member 71, as shown in FIG. 9, the holder member 73 and the base member 71 form a continuous surface, and a charging stand having a good appearance can be obtained. ..
That is, the charging stand 70a and the charging stand 70b are detachable from the AC adapter 80 for charging the storage battery 3 of the vacuum cleaner main body 1 and the AC adapter 80, and the base member 71 and the stand such as the charging stand 70a. It can be selectively used in two ways: a combination of the member 72 and the holder member 73, and a combination of the base member 71 and the holder member 73 such as the charging stand 70b. It is possible to provide a vacuum cleaner in which the storage method at the time of charging can be selected mainly according to the usage state of the vacuum cleaner 100, such as whether the vacuum cleaner 100 is used in a handy state or a stick state.
The stand member 72 may be configured to be divisible into a plurality of members. In this case, it is possible to provide a vacuum cleaner provided with a charging stand that can select a desired height.
The holder member 73 may be provided with a hole on the wall surface that can be fixed with a screw or the like.

11 (a) and 11 (b) are enlarged views of the output plug 81 mounting portion of the AC adapter 80 of the holder member 73. The upper surface 73b of the holder member 73 is provided with an opening 73i to which the output plug 81 of the AC adapter 80 can be attached, and by attaching the output plug 81 here, it is used as a charging stand for charging the vacuum cleaner 100.

FIG. 16 is a cross-sectional view showing a connection state between the main body terminal portion and the output plug 81. When the guide portion 73a of the charging stand 70 and the fitting recess 17a of the main body are fitted, the output plug 81 located at the center thereof and the input jack 17b are fitted, and the AC adapter 80 and the vacuum cleaner 1 are electrically connected. .. While the vacuum cleaner main body 1 is mounted on the charging stand 70, the output plug 81 and the input jack 17b are kept in contact with each other, and the storage battery 3 is continuously charged.

Further, since the output plug 81 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). The state) is not released.

In the charging stand 70 configured in this way, since the output plug 81 is formed on the upper surface 72b of the stand member 72, when the main body terminal portion 17 is attached to the output plug 81, it is located at a position close to the user's line of sight. Therefore, it becomes easy to insert the main body terminal portion 17 into the output plug 81, and it becomes easy to set the vacuum cleaner main body 1 on the charging stand 70.

Further, in the charging stand 70, the output plug 81 is formed on the upper surface 72b of the stand member 72. That is, since the output plug 81 is formed at a position higher than the floor surface, it is difficult for dust to accumulate on the output plug 81, and it is also possible to reduce dust rising from the floor surface and adhering to the output plug 81.

Further, in the vacuum cleaner 100 set on the charging stand 70, since the output plug 81 is located at a position close to the center of gravity of the vacuum cleaner 100 (the position of the electric blower 40 and the storage battery 3), the output plug 81 receives the vicinity of the center of gravity. As a result, the vacuum cleaner main body 1 can be stably held on the charging stand 70 during charging.

Further, by setting the vacuum cleaner 100 on the charging stand 70, it can be charged with the dust case 2 removed, so that the dust case 2 can be charged even while it is being washed and dried.

Further, the output plug 81 is facing upward, and the main body terminal portion 17 is connected to the output plug 81 from above. As a result, the weight of the vacuum cleaner 100 can be applied to the output plug 81 in a focused manner, so that the main body terminal portion 17 and the output plug 81 can be reliably connected.

72g and 73g to which the output cord 82 of the AC adapter 80 can be wired are provided on the back surfaces of the stand member 72 and the holder member 73.

Although not shown, the charging stand 70 can be stored and charged with the standard suction port 400 and other attachments connected to the vacuum cleaner 100.

Note that the charging stand 70 can be used as a stand for storing the vacuum cleaner 100 even when the AC adapter 80 is not connected and the storage battery 3 is not charged.

Further, in the state where the vacuum cleaner 100 is housed in the charging stand 70, the storage battery 3 is located at the upper end and the lock member 13 is located at the upper end of the storage battery 3, so that the storage battery 3 can be easily attached and detached. it can.
In other words, in the vacuum cleaner storage stand that can store the vacuum cleaner, the vacuum cleaner storage stand has a base member 71, a stand member 72, and a holder member 73, and only the base member 71 and the holder member 73 are connected. The vacuum cleaner storage stand in the first state (handy state) can store the vacuum cleaner, and the vacuum cleaner storage stand in the state where the base member 71, the stand member 72, and the holder member 73 are connected is the second state (stick). If it is a vacuum cleaner storage stand that can store the vacuum cleaner in the state), it is possible to provide an electric vacuum cleaner that can select the storage method at the time of storage according to the usage state of the vacuum cleaner 100.

FIG. 17 is a usage pattern diagram when cleaning the floor surface with a stick-state vacuum cleaner.
In FIG. 17, the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (with the airtightness holding member 90 attached) to make a stick state, and the vacuum cleaner 100 is projected forward from the user to raise the floor surface. When cleaning. In this case, the user can perform cleaning while moving the vacuum cleaner 100 back and forth while gripping the second grip portion 12a2 of the handle portion 12. Further, although not shown, when cleaning the floor surface with the vacuum cleaner 100 located on the left and right sides of the user, the user grips the first grip portion 12a1 of the handle portion 12. , The vacuum cleaner 100 can be moved 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. 18 is a usage pattern diagram when cleaning a high place with a stick-state vacuum cleaner.
By the way, in an electric vacuum cleaner whose center of gravity is on the tip side when it is in the stick state (see Japanese Patent Application Laid-Open No. 2016-137165), when cleaning the electric vacuum cleaner at a place higher than the floor surface, the user of the electric vacuum cleaner Since it is necessary to lift the tip upward, it becomes easy to put a burden on the wrist.

Therefore, in the present embodiment, as shown in FIG. 18, the electric blower 40 (see FIG. 6) 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 center of gravity G of the vacuum cleaner 100 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 at a place higher than the floor surface, it becomes easy to clean and the usability can be improved. Although the case of cleaning the stairs has been described as an example in FIG. 18, it is also effective when the electric vacuum cleaner 100 is lifted to clean the panel of the indoor unit of the air conditioner.
FIG. 19 shows a diagram of the hand operation unit 12b. The hand operation unit 12b is composed of, for example, three buttons, a “strong / turbo” button 12b1, a “standard / turbo” button 12b2, and an “off” button 12b3. By pressing the "strong / turbo" button 12b1 or the "standard / turbo" button 12b2 while the electric blower is stopped (pressing the "off" button 12b3 and then not pressing any other button) It can be operated in the "strong" operation mode or the "standard" operation mode. It is possible to operate with higher suction power in the "strong" operation mode than in the "standard" operation mode. Furthermore, during the "strong" operation mode and the "standard" operation mode, the buttons on the hand operation unit corresponding to each operation mode ("strong / turbo" button 12b1 during the "strong" operation mode, "standard" By pressing the "standard / turbo" button 12b2) again during the operation mode of, it becomes possible to operate in the "turbo" operation mode in which the suction power is temporarily increased (for example, about 5 seconds). As a result, it is possible to immediately enter a mode in which the suction power is temporarily increased during cleaning, and it is possible to operate by temporarily increasing the suction power such as dust that has entered the back of the carpet. As a method for increasing the suction force, for example, there is a method for increasing the input to the electric blower.
The suction power of each "turbo" mode operated by pressing the "strong / turbo" button 12b1 or the "standard / turbo" button 12b2 twice is the same. As a result, it is possible to go to the same "turbo" operation mode by pressing the button once in both the "strong" operation mode and the "standard" operation mode. As a result, it is possible to immediately enter a mode in which the suction force is temporarily increased even during cleaning in each operation mode.
When the "turbo" operation mode ends (temporarily, for example, about 5 seconds), it returns to the operation mode in which it was operated before the button was pressed. For example, if the "strong / turbo" button 12b1 is pressed during the "strong" operation mode to operate in the "turbo" operation mode, the operation returns to the "strong" operation mode and the "standard / turbo" operation mode is set. When the "turbo" button 12b2 is pressed to operate in the "turbo" operation mode, the operation returns to the "standard" operation mode.
Here, the continuous use time when operating only in the "strong" operation mode or the "standard" operation mode is shortened by the amount of operation by operating in the "turbo" operation mode (for example, "turbo"). If you operate once in the operation mode of ", the continuous use time of other operation modes will be shortened by about 5 seconds).
