As shown in FIG. 5, the connection part 91b of the airtight holding member 90 is fastened to the left and right sides, and is formed with extension parts 91b1 and 91b1 extending toward the rear. Between the left extension portion 91b1 and the right extension portion 91b1, a concave portion 91b2 is formed in a plan view. The concave portion 91b2 is fitted with the front end portion 10d1 of the protruding portion 10d formed on the front end upper surface of the main body portion 10. As shown in FIG. Thereby, the positioning in the front-rear direction and the left-right direction of the airtight holding member 90 with respect to the connection port 10a (refer to FIG. 2 ) is performed.

The introduction pipe 14 formed in the main body 10 is formed to extend obliquely rearward to the right, and then extend downward, and is connected to the inflow port 2b (see FIG. 2 ) of the dust box 2 . Thereby, a swirling flow can be generated in the accommodating part 2a of the dust box 2, and the dust separation by centrifugal force can be performed efficiently.

The width of each of the dust box 2 and the battery 3 is formed to be slightly shorter than the width W of the main body portion 10 . In other words, the dust box 2 and the battery 3 are configured not to protrude from the side of the main body portion 10 . Thereby, regardless of whether the user cleans with the left hand or the right hand, the vacuum cleaner 100 can be smoothly moved in the front-rear direction, and the usability can be improved.

FIG. 6 is a cross-sectional view taken along line VI-VI of FIG. 5 . In addition, FIG. 6 is the state which removed the airtight holding member 90 from the vacuum cleaner 100. As shown in FIG. 6 , an electric blower 40 is accommodated in the motor case portion 11 of the main body portion 10 . Moreover, in the motor box part 11, the main body board|substrate 50 (control board|substrate) which controls the vacuum cleaner main body 1 is accommodated in the lower part of the electric blower 40.

The electric blower 40 is horizontally arranged so that the rotation drive shaft 40a faces the front-rear direction. In addition, the air discharged from the electric blower 40 flows to the main body substrate 50 arranged below the electric blower 40 , and cools the main body substrate 50 . In addition, the air that cools the main body substrate 50 is used to cool the battery 3 .

The main body substrate 50 includes an upper substrate 50a and a lower substrate 50b which are divided into upper and lower parts and arranged in two stages, and are mainly mounted on the opposing surfaces (the lower surface of the upper substrate 50a and the upper surface of the lower substrate 50b). Various parts. Most of the air discharged from the electric blower 40 flows so as to cool the parts (heat-generating parts) of the main body substrates 50 which are arranged opposite to each other. In addition, 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 from the rear side to the front side in the resin case 51, and then becomes a passing resin The lower side of the bottom surface of the case 51 flows to the side of the battery 3 .

Moreover, the electric blower 40 and the main body board|substrate 50 are arrange|positioned so that it may mutually overlap in an up-down direction. Therefore, the dimension in the front-rear direction can be shortened. Moreover, the electric blower 40 can shorten the dimension of the front-back direction (overall length) of the main body part 10 by forming the motor case part 11 so that the handle part 12 side may protrude.

Moreover, the electric blower 40 and the main body board|substrate 50 are located below the 1st grip part 12a1 of the handle part 12. Thereby, when the user grips and operates the grip portion 12a1, since the center of gravity of the vacuum cleaner 100 is in the vicinity of the lower side of the first grip portion 12a1, the vacuum cleaner 100 is used with the front end facing upward. In this case, the vacuum cleaner 100 can be held stably.

Moreover, between the 2nd grip part 12a2 and the back surface 11d of the motor case part 11, the clearance gap 12d of the width dimension H2 which is wider than the width dimension H1 is formed. In this way, when the first grasping part 12a1 is grasped and cleaned, since the system can hold the wrist in a state where the wrist is stretched, the system can be used without strongly grasping the first grasping part 12a1. The cleaner 100 moves forward and backward. Moreover, in the case of grasping and cleaning the second grasping portion 12a2, since it is necessary to deeply insert the hand (finger) into the gap 12d and firmly grasp it, the width dimension H2 is set to be wider by making the width dimension H2 wider. The dimension H1 is wider, and the second holding part 12a2 can be held stably.

Moreover, the thickness T1 of the 1st holding part 12a1 is formed thin, and the thickness T2 of the 2nd holding part 12a2 is formed thicker than the thickness T1. That is, the 1st holding part 12a1 is thin, and the 2nd holding part 12a2 is formed thick. In this way, when the second grip portion 12a2 is gripped and cleaned, the thickness T2 of the second grip portion 12a2 is made thick, so that the second grip portion 12a2 can be easily gripped tightly and the second grip portion 12a2 can be strength increased.

The storage battery 3 can be constituted by, for example, a lithium-ion battery with high energy efficiency. In addition, the battery 3 is arranged below the second grip portion 12 a 2 of the handle portion 12 . In this way, by arranging the battery 3 at the rear end of the cleaner 100, since the center of gravity of the handle portion 12 is close to the second grip portion 12a2, when the cleaner 100 is used with the front end facing upward, The system can make the operation feel light.

The locking member 13 is formed with a button-type operating portion 13a at the rear end. The operation portion 13a includes an arm portion 13b extending forward, and the front end of the arm portion 13b is supported by the main body portion 10 . In addition, the arm portion 13b is pressed downward by the spring 13c. Thereby, when the locking member 13 is fitted in the locking recessed portion 3g and is locked, the operation portion 13a is prevented from coming out of the locking recessed portion 3g. When the battery 3 is detached from the main body portion 10, the operation portion 13a can be pulled out from the locking recess 3g while resisting the pressing force of the spring 13c by pressing the operation portion 13a.

In this way, by making the storage battery 3 a removable type, it becomes easier to exchange the storage battery 3 than if the storage battery is not removable. In addition, by preparing the spare battery 3 and the charging case capable of charging the spare battery 3 as an option, when the battery on the main body side of the vacuum cleaner 100 is consumed, the spare battery 3 In exchange, it becomes possible to extend the cleaning time. This configuration is effective, for example, when cleaning a large floor surface such as a store.

As shown in FIG. 6 , when the surface passing through the front end surface of the connection port 10a of the main body 10 is designated as R1, the front end 2f of the dust box 2 and the surface R1 (which extends in the vertical direction with respect to the paper surface) are set as R1. planes) will be formed in such a way that they become almost the same plane. In addition, the front end 2f of the dust box 2 does not protrude further forward than the surface R1. Thereby, even when cleaning is performed without attaching the airtight holding member 90 to the cleaner body 1, the front end of the connection port 10a can be brought into contact with a hard floor such as a floor. Clean on one side.

In the dust box 2, the filter screen 5 is accommodated at the rear end in the axial direction of the accommodating portion 2a. The filter screen 5 is formed by being folded in a skirt shape, so that the screen area can be increased, and the pressure loss caused by the filter screen 5 can be reduced.

In addition, the filter 5 is constituted by, for example, a high-density HEPA filter (High Efficiency Particulate Air Filter). The so-called HEPA filter refers to 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 volume, and an initial pressure loss of 245Pa or less.

The input jack 17b is connected to a terminal (not shown) connected to the terminal portion 3b of the battery 3 by a lead wire (not shown).

FIG. 13 is an external view of the AC adapter 80 . In addition, in this embodiment, the AC adaptor is directly connected to the socket, but the AC adaptor 80 body can also be connected to the socket via a wire with a plug attached. .

FIG. 14 is an external view showing a state in which the AC adapter 80 is directly connected to the vacuum cleaner for charging. By configuring in this way, even when there is no place where the charging stand is placed, it becomes possible to perform charging in a space-saving manner.

Fig. 15(a) is a perspective view showing a state in which the AC adapter 80 is mounted on the support member of the charging stand, and Fig. 15(b)(c)(d) is a central sectional view.

The user turns the cleaner body 1 downward and lowers the cleaner body 1 from above the output plug 81 , so that the body terminal 17 is connected to the output plug 81 . At this time, since the output plug 81 is formed facing upward, the main body terminal portion 17 can be surely connected to the output plug 81 by the weight of the cleaner 100 .

FIG. 16 is a cross-sectional view showing the connection state between the main body terminal portion and the output plug 81 . If the guide portion 73a of the charging stand 70 is fitted with the fitting recess 17a of the main body, the output plug 81 at the center of the charging stand 70 is fitted with the input jack 17b, and the AC adapter 80 and the vacuum cleaner 1 are fitted together. are electrically connected. While the cleaner body 1 is attached to the charging stand 70, the output plug 81 and the input jack 17b are maintained in a state of being in contact, and the charging of the battery 3 is continued.

In addition, since the output plug 81 is fitted with the main body terminal portion 17 in a concave and convex manner, for example, even if the user touches the vacuum cleaner main body 1 during charging, there is no conduction between the main body terminal 17d and the terminal 73c. The state (contact state) is released.

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

Also, at the charging stand 70 , the output plug 81 is formed on the upper surface 72 b of the upright member 72 .

In addition, in the vacuum cleaner 100 mounted 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 battery 3), by using the output plug 81 To support the vicinity of the center of gravity, the vacuum cleaner body 1 can be stably held on the charging stand 70 during charging.

In addition, by placing the vacuum cleaner 100 on the charging stand 70, since it is possible to charge the dust box 2 in a state where the dust box 2 is removed, even when the dust box 2 is being washed and dried , can also be charged.

In addition, the output plug 81 is directed upward, and the main body terminal portion 17 is connected to the output plug 81 from above. Thereby, since the own weight of the cleaner 100 can be focused on the output plug 81, the main body terminal portion 17 and the output plug 81 can be surely connected.

Grooves 72g and 73g are provided on the rear surfaces of the upright member 72 and the support member 73 so that the output wire 82 of the AC adapter 80 can be wired.

In addition, although not shown, the charging stand 70 can also be stored and charged in a state where the standard suction port 400 or other accessories are connected to the vacuum cleaner 100 .

In addition, the charging stand 70 can be used as a stand when the vacuum cleaner 100 is accommodated even when the AC adaptor is not connected and the battery 3 is not charged.

Moreover, since the battery 3 is located at the upper end and the locking member 13 is located at the upper end of the battery 3 when the cleaner 100 is housed in the charging stand 70, the battery 3 can be easily attached and detached. In other words, in a vacuum cleaner storage table capable of accommodating a vacuum cleaner, as long as the vacuum cleaner storage table is provided with the base member 71, the upright member 72 and the support member 73, and only the base member 71 and the support member 73 are connected in a state The vacuum cleaner accommodating stand is capable of accommodating the vacuum cleaner in the first state (hand-held state), and the vacuum cleaner accommodating stand in the state in which the base member 71, the erecting member 72 and the supporting member 73 are connected can accommodate the second state (upright state). The vacuum cleaner 100 has the effect of providing a vacuum cleaner that can select the storage method during storage according to the use state of the vacuum cleaner 100 .

Fig. 17 is a view of the usage form when the floor is cleaned with the vacuum cleaner in the upright state. Fig. 17 shows the extension pipe 300 and the standard suction port 400 are connected to the vacuum cleaner 100 (maintained in the state where the airtight holding member 90 is installed), and the vacuum cleaner 100 is set to the upright state, and the vacuum cleaner 100 is facing the front of the user. Prominently for cleaning the ground. In this case, the user can perform cleaning by moving the vacuum cleaner 100 back and forth while holding the second holding portion 12a2 of the handle portion 12 . In addition, although not shown, when cleaning the floor with the vacuum cleaner 100 positioned on the left and right sides of the user, the user can hold the first holding portion 12a1 of the handle portion 12 while holding the first holding portion 12a1 of the handle portion 12. Move the vacuum cleaner 100 back and forth. In this way, when the user cleans the floor, the user can perform cleaning by changing the position where the grip portion 12 is grasped.

Fig. 18 is a view of a usage form when cleaning a high place with a vacuum cleaner in an upright state. In addition, in the case of a vacuum cleaner (Japanese Patent Application Laid-Open No. 2016-137165) whose center of gravity is positioned on the front end side in the upright state, it is used when cleaning a place higher than the ground. Since it is necessary to lift up with the front end of the vacuum cleaner facing upwards, it is easy to put a burden on the wrist.

Therefore, in this embodiment, as shown in FIG. 18 , since the vacuum cleaner 100 is a heavy electric vacuum cleaner 40 (see FIG. 6 ) and the battery 3 are located close to the handle portion 12 (close to the one at hand) position), so the center of gravity G of the vacuum cleaner 100 is close to the user's hand. Thereby, even in the case where the vacuum cleaner 100 is placed in the upright state and the vacuum cleaner 100 is used to clean a place higher than the ground, the cleaning becomes easy, and the usability can be improved. In FIG. 18, although the case where the steps are cleaned is described as an example in series, it is also effective when the vacuum cleaner 100 is lifted up to clean the panel of an indoor unit of an air conditioner. In FIG. 19, the figure of the operation part 12b at hand is shown. The operation unit 12b at hand is constituted by, for example, three buttons of a "strong/quick" button 12b1, a "standard/quick" button 12b2, and a "off" button 12b3. When the vacuum cleaner is in a stopped state (after pressing the "OFF" button 12b3 without pressing other buttons), by pressing the "strong/fast" button 12b1 or the "standard/fast" button 12b2, the It can be operated in the "strong" operation mode or the "standard" operation mode. Compared with the "standard" operation mode, the "strong" operation mode enables the operation with higher attractiveness. Furthermore, in the "strong" operation mode or the "standard" operation mode, press the button of the operation part at hand corresponding to each operation mode again (in the "strong" operation mode, press the "strong"/ Pressing the "Rapid" button 12b1 and pressing the "Standard/Rapid" button 12b2) in the "Standard" operation mode is performed in the "Rapid" operating mode that can temporarily (for example, 5 seconds) increase the attraction force. run. Thereby, the system can immediately enter the mode of temporarily increasing the attractive force during cleaning, and can perform the operation of temporarily increasing the attractive force, such as dust trapped in the depths of the carpet. As a method for increasing the attraction force, for example, there is a method for increasing the input to the electric blower. The attractiveness of the respective "rapid" modes performed by pressing the "strong/rapid" button 12b1 or the "standard/rapid" button 12b2 twice is the same as each other. Thereby, whether in the "strong" operation mode or in the "standard" operation mode, the same "rapid" operation mode can be performed by pressing the button once. Thereby, regardless of the operation mode, it is possible to immediately enter the mode for temporarily enhancing the attractiveness. When the "rapid" operation mode ends (temporarily, for example, when the 5-second time period expires), it returns to the operation mode that was in progress before the button was pressed. For example, when the "strong/rapid" button 12b1 is pressed in the "strong" operation mode and the operation is performed in the "rapid" operation mode, it returns to the "strong" operation mode. When the "standard/rapid" button 12b2 is pressed in the operation mode of "" and the operation is performed in the "rapid" operation mode, it returns to the "standard" operation mode.

Here, the continuous use time when the operation is performed only in the "strong" operation mode or only in the "standard" operation mode is caused by the operation in the "rapid" operation mode. , and shortens according to the amount of operation (for example, when one operation is performed in the "rapid" operation mode, the continuous time of other operation modes will occur for about 5 seconds. shorten).
