Are provided with substantially cylindrical support shaft portions 175 and 175 that pivotally support the rear driven wheels 164 and 164.

  Upper base case 167 has an upper connection opening 176 in which the lower end portion of connection air passage portion 87 is airtightly connected. Then, the lower end portion of the connection air passage portion 87 is airtightly connected to the upper connection opening 176, so that the suction space portion 178 partitioned in the parent machine case body 161 is collected via the connection air passage portion 87. The dust unit 59 is configured to communicate with the suction side.

  The rotating brush 162 is rotatably attached to the main unit suction port 171.

  The front driven wheels 163 and 163 are located on both sides of the rotating brush 162, and are fitted in recesses 179 formed by cutting out on both sides of the base case body 161.

  Next, the operation of the above embodiment will be described.

  First, when cleaning a relatively wide area such as a floor surface of a room, the vacuum cleaner 1 is used. That is, the vacuum cleaner 2 is used in a state where it is mounted on the apparatus main body 3.

  At this time, the terminals 19 and 19 on the electric vacuum cleaner 2 side and the main body terminals 143 and 143 on the apparatus main body 3 side are electrically connected, so that the switch 26 and the main unit control means are electrically connected. A part of the electric power of the parent device secondary battery 57 is supplied to the child device secondary battery 21 while being controlled by the parent device control means, and the child device secondary battery 21 is charged.

  When the operator operates the predetermined switch 26, the power supplied from the master secondary battery 57 to the master electric blower 56 is controlled by the master control means, and the master electric blower 56 is driven and the valve body Assume that 98 is switched to position P1 (FIG. 1 (a)).

  Then, when the operator grips the grip portion 25 and causes the vacuum cleaner 1 to run back and forth on the floor surface, the rotating brush 162 rotates and scrapes off dust on the floor surface. Dust is sucked together with air by the negative pressure generated by driving the main electric blower 56.

  The sucked air becomes intake air and is collected together with dust from the suction space portion 178 of the base unit floor brush portion 52 through the upper connection opening 176, the connection air passage portion 87, and the connection pipe 97 of the communication air passage portion 86. Sucked into the dust unit 59.

  In the dust collection unit 59, the intake air and dust are sucked into the separation chamber 83 from the dust suction port 81 via the guide air passage tube 82, and around the dust separation means along the inner wall of the separation chamber 83. , The relatively large dust is centrifuged and flows from the introduction hole into the front air passage 125 through the opening 128, and the small dust is removed from the net filter of the opening 104 or the dust separating means. Collected by net filter.

  Dust flowing into the front air passage 125 is accommodated in the main dust collection chamber 122, and further when the air passes through the dust collector connection opening 129 of the side air passage 126, the main dust collection chamber. It is compressed in the unit 122.

  In addition, the intake air that has passed through the dust separation means flows into the filter unit 76 through the circular opening 103 together with the intake air that has passed through the opening 104 and the intake air that has passed through the dust collector connection opening 129. When passing through the pleated filter 115 of the filter body 112, finer fine dust is collected.

  The intake air that has passed through the pleated filter 115 is sucked into the main electric blower 56 through the first side communication air passage 66 and the main communication air passage 65, and passes through the main electric blower 56. Exhaust air is generated and exhausted from the main unit exhaust hole 68 to the outside of the main unit main body case 55 via the exhaust air passage 67.

  Further, when the master electric blower 56 is stopped by operating the predetermined switch 26, the master control means drives the motor 116, so that the pleat filter body 112 rotates in the circumferential direction for a predetermined time, and the dust removing means is pleated. By flipping the filter 115, the fine dust collected by the pleated filter 115 is dropped into the storage case 111. The fine dust that has been dropped is transported to the discharge opening by the sweeper and separated again. Returned to part 75.

  On the other hand, the vacuum cleaner 2 alone is used to clean a relatively narrow place, for a short time, or for cleaning a filter of an air conditioner. That is, the vacuum cleaner 2 is used by being detached from the apparatus main body 3.

  At this time, during the usage time of the vacuum cleaner 1, the secondary battery 21 of the slave unit is substantially fully charged by the secondary battery 57 of the master unit.

  When the operator presses each clamp button 146 from the left and right, the operation of each clamp portion 144 opens each clamp body 145 to the left and right, and the engagement recess 20 between these clamp portions 144 and the body connecting portion 16 of the vacuum cleaner 2. And the vacuum cleaner 2 can be detached from the apparatus main body 3.

  Further, when the vacuum cleaner 2 is completely removed from the apparatus main body 3, the electrical connection between the terminals 19 and 19 and the main body terminals 143 and 143 is released, and each child is urged by the urging force of the child machine suction portion urging means. The machine suction part 34 rotates so as to open in the left-right direction with respect to the child machine body part 33.

  In this state, when the operator grips the grip portion 25 and operates the switch 26, the slave unit control means controls power feeding from the slave unit secondary battery 21 to the slave unit electric blower 12, so that the slave unit electric blower 12 drives.

  Then, the operator slides the handset floor brush 8 with respect to the surface to be cleaned, so that the brush bristle portion 42 wipes off dust on the surface to be cleaned and air is sucked together with dust from each handset inlet 41. .

  This sucked air becomes an intake air and is sucked into the handset dust collecting chamber 11 through the communication pipe and the extension pipe portion 7, and dust contained therein is removed when passing through the filter, and the handset electric blower 12 Is sucked into the suction side.

  Thereafter, the intake air that has passed through the child machine electric blower 12 becomes exhaust air and is exhausted from the child machine exhaust hole 14 to the outside of the cleaner body 5.

  Further, when the cleaning with the vacuum cleaner 2 is completed, the operator stops the slave unit electric blower 12 by operating a predetermined switch 26, and the vacuum cleaner 2 while fitting the slave unit floor brush 8 to the detachable recess 61. Is attached to the apparatus main body 3.

  At this time, the child machine floor brush 8 is such that the lower end side of each child machine suction portion 34 abuts on each upper inclined surface portion 156 of the support 151 on the apparatus main body 3 side so that both sides of each child machine suction portion 34 are It rotates upward around the suction port 41 and is folded and accommodated in the lower recess 136 of the detachable recess 61.

  At the same time, the communication pipe portion 31 of the child machine floor brush 8 is sequentially accommodated in the intermediate recess 135 and the extension pipe portion 7 is sequentially accommodated in the upper recess 134, and the cleaner body 5 extends along the guide ribs 148 and 148 in the second portion of the receiving portion 137. By fitting into the fitting portion 142, the main body connecting portion 16 spreads the clamp main body 145 left and right, while the bent connection portion 95 is inserted into the communication opening 17, and the handset dust collecting chamber 11 is connected to the communication opening 17, The bent connecting portion 95, the upper connecting air passage 93, the second side communication air passage 91, and the communication air passage portion 86 communicate with the suction side of the dust collecting unit 59, and the clamp main body 145 is an engagement recess of the main body connection portion 16. The vacuum cleaner 2 is fixed to the apparatus main body 3 by being engaged with 20 respectively.

  When the operator operates the predetermined switch 26, the connection detection means detects the connection state of the vacuum cleaner 2 to the apparatus body 3, and based on this detection, the master control means moves the valve body 98 to the position P2. Switching (FIG. 1 (b)), and the electric power from the main unit secondary battery 57 is transmitted to the main unit electric blower 56.

  The negative pressure generated by the driving of the main electric blower 56 is sequentially applied to the communication air passage portion 86, the second side communication air passage 91, the upper connection air passage 93, and the bent connection portion 95, thereby Dust stored in the dust collection chamber 11 is sucked into the dust collection unit 59 through the bent connection portion 95, the upper connection air passage 93, the second side communication air passage 91, and the communication air passage portion 86 and captured. Be collected.

  Dust collected by the dust collection unit 59 can be removed by operating the detachable clamp 133 to remove the dust collection unit 72 from the main unit body case 55, and by operating the release button on the trash can etc. The dust collector lid 131 rotates through the part 132, and the dust accumulated in the master dust collecting chamber 122 is discarded.

  When the vacuum cleaner 1 is not used, the main battery secondary battery 57 is appropriately charged by the charger 70 by connecting the power cord to a commercial AC power source or the like.

  As described above, according to the above-described embodiment, when the vacuum cleaner 2 is attached to the apparatus body 3, the handset dust collecting chamber 11 and the dust collecting unit 59 communicate with each other through the communication opening 17. The dust collected in the machine dust collection chamber 11 can be moved to the dust collection unit 59 having a larger capacity than the machine dust collection chamber 11 by driving the machine electric blower 56. The dust chamber 11 need only be able to temporarily store dust, and it is not necessary to make the handset dust collection chamber 11 larger than necessary or to attach a large filter. Can be reduced in size and weight.

  As a result, the vacuum cleaner 2 that cleans a small amount of dust or cleans a high position by removing it from the apparatus main body 3 can be made small and light, so the vacuum cleaner 2 can be used easily. This improves usability and handling.

  Further, when the vacuum cleaner 2 is mounted on the apparatus main body 3, the communication opening 17 is opened to the communication opening 17 of the child machine dust collection chamber 11 so that the child machine dust collection chamber 11 and the dust collection unit 59 communicate with each other. By providing the lid 18 that closes the communication opening 17 with the vacuum cleaner 2 removed from the main body 3, dust is spilled from the handset dust collection chamber 11 when the vacuum cleaner 2 is cleaned alone. It is possible to prevent dust from spilling when the vacuum cleaner 2 is attached to and detached from the apparatus main body 3.

  In addition, the handset dust collecting chamber 11 can be communicated with the dust collecting unit 59 or the handset dust collecting chamber 11 and the dust collecting unit 59 can be separated simply by detaching the vacuum cleaner 2 from the apparatus body 3. Compared with the case where the operation of attaching / detaching the vacuum cleaner 2 to / from the apparatus main body 3 and the communication operation of the dust collecting chamber 11 and the dust collecting unit 59 are separated, the operation is performed. Property is improved.

  Furthermore, the main unit electric blower 56 is driven in a state where the vacuum cleaner 2 is mounted on the apparatus main body 3 by the bent connection portion 95, the upper connection air passage 93, the second side communication air passage 91, and the communication air passage portion 86. By forming a suction structure 96 capable of sucking the dust in the handset dust collecting chamber 11 into the dust collecting unit 59 through the communication opening 17, the dust in the handset dust collecting chamber 11 is transferred to the dust collecting unit 59. You can inhale efficiently.

  Then, the valve body 98 is provided in the connection pipe 97 of the communication air passage 86, and when the dust in the handset dust collection chamber 11 is sucked into the dust collection unit 59, the valve body 98 is switched to the position P2 to collect the dust collection unit 59. By blocking the air passage that communicates with the main unit floor brush part 52, when the dust in the sub unit dust collection chamber 11 is sucked into the dust collection unit 59, it prevents dust from being sucked in from the main unit floor brush part 52 side. In addition, the dust in the handset dust collection chamber 11 can be sucked into the dust collection unit 59 more efficiently.

  Further, the apparatus main body 3 accommodates heavy objects such as the main machine electric blower 56 and the main battery secondary battery 57 in the lower part of the main machine main body case 55, so that these heavy objects are accommodated on the upper side. Thus, the operability of the electric vacuum cleaner 1 is improved.

  Further, in the child machine floor brush 8, each child machine suction part 34 can be folded with respect to the child machine body part 33, and each child machine suction part 34 is in a folded state when the vacuum cleaner 2 is attached to the apparatus body 3. By doing so, it is possible to make the handset floor brush 8 relatively large and improve the suction performance of the electric vacuum cleaner 2, while taking up space when the electric vacuum cleaner 2 is attached to the apparatus main body 3. Absent.

  Further, by providing the support 151 for deforming each child machine suction part 34 in the folded state in the detachable recess 61, when attaching the vacuum cleaner 2 to the apparatus body 3, each child machine suction part 34 is folded at the same time. Therefore, the attachment work to the apparatus main body 3 of the vacuum cleaner 2 becomes easy.

  Moreover, since the vacuum cleaner 1 can be configured without using a relatively heavy hose or the like, the appearance of the vacuum cleaner 1 when stored is improved, and restrictions on the storage state of the vacuum cleaner 1 are reduced. It can correspond to the storage state of various styles.

  Further, when the vacuum cleaner 2 is attached to the apparatus main body 3, the secondary secondary battery 57 is directly charged by the secondary secondary battery 57. For example, the secondary secondary battery 57 is converted into a direct current power source after the commercial alternating current power source or the like is converted. Compared with the case where the battery 21 is charged, the charging time of the handset secondary battery 21 can be shortened, and the charging efficiency can be improved.

  In particular, the vacuum cleaner 2 as a slave unit is often used for a short period of time compared to the vacuum cleaner 1, so that the secondary battery 21 can be charged in a short time. For example, it becomes possible to complete the charging of the secondary battery 12 while cleaning the floor surface of the main cleaning area with the electric vacuum cleaner 1. When the vacuum cleaner 2 is removed from the apparatus main body 3 when cleaning, the usability of the vacuum cleaner 2 is improved.

  Then, by providing a charger 70 that charges the parent device secondary battery 57, the parent device secondary battery 57 having a large capacity can be charged using a commercial AC power source or the like.

  Moreover, by storing the charger 70 in the apparatus main body 3, the storage space of the vacuum cleaner 1 can be suppressed as compared with the case where a separate charger is used.

  In the above embodiment, the suction structure 96 is not limited to the above configuration as long as the handset dust collection chamber 11 and the dust collection unit 59 are communicated with each other through the communication opening 17.

  Further, the opening / closing structure of the lid 18 may be, for example, one that opens and closes by sliding, and is not limited to the above configuration.

  Furthermore, it is also possible to use a separate charger for attaching and charging the vacuum cleaner 1 instead of the charger 70 built in the apparatus main body 3. In this case, the apparatus main body 3 does not need a power cord or the like, and only the charging terminal connected to the charger needs to be provided in the apparatus main body 3. Therefore, the apparatus main body 3 can be further downsized. .

  And if the position of each terminal and each main body terminal can be electrically attached / detached by attaching / detaching the vacuum cleaner 2 to / from the apparatus main body 3, the position and shape of the terminals and the like are not limited to the above configurations.

  Further, details of the apparatus main body 3 or the vacuum cleaner 2 such as a connection structure of the electric vacuum cleaner 2 to the apparatus main body 3 are not limited to the above configuration.
