Description

  The present invention relates to a vacuum cleaner including a dust collector that is detachably attached to a main body case.

  As a conventional vacuum cleaner, for example, a configuration described in Japanese Patent Publication No. 58-1936 is known (for example, see Patent Document 1).

  The vacuum cleaner described in Japanese Patent Publication No. 58-1936 includes a case body that houses an electric blower, and a dust collector that has a suction port that is detachably attached to a front side that is an intake side of the case body and that connects a hose. And a case.

  The case body has a communication hole communicating with the intake port of the electric blower on the front surface, and a first handle portion is provided on the upper portion. A pair of traveling wheels are provided on both sides of the case body. On the other hand, the dust collection case has an opening that opens to the front surface and opens to the rear surface an opening that communicates with the communication hole so as to face the front periphery of the case body. A filter body is detachably closed and attached to the opening, and a dust collection chamber is defined inside. In addition, a swivel wheel is provided at the lower part of the dust collection case. Furthermore, a second handle is provided on the upper part of the dust collection case. A dust collection case is integrally attached to the front portion of the case body to form a main body case, and the swivel wheel of the dust collection case and the traveling wheel of the case body can travel on the floor surface.

  In cleaning, the dust collection case is attached to the front side of the case body, and the air blower inlet of the electric blower is in communication with the dust collection chamber in the dust collection case through the filter body. After that, the electric blower is driven, and the dust sucked in with the air through the hose connected to the suction port of the dust collecting case flows into the dust collecting chamber, and the dust is separated by the filter body and only the air is filtered. The air is sucked from the intake port of the electric blower, exhausted into the case body, and further exhausted to the outside air.

  The dust trapped in the dust collection chamber of the dust collection case is removed from the case body with the second handle of the dust collection case, and the filter body is removed from the dust collection case to open the opening. And the structure which inverts an opening part so that it may face below, and discharges dust from the opening part opened is taken.

  However, in the vacuum cleaner described in the above Japanese Patent Publication No. 58-1936, the main body case is configured, that is, dust is collected in a dust collecting case having a suction port to which the hose is attached. Since the dust collection case must be reversed or the dust collection case must be reversed after removing the hose, the workability is poor.

  On the other hand, as a conventional vacuum cleaner, for example, a configuration using a dust bag is known. The vacuum cleaner using the dust bag has a main body case having a dust collection chamber whose upper surface is opened and closed by a lid on the front surface of the electric blower chamber that houses the electric blower. In addition, a suction port that is detachably connected to the hose and communicates with the dust collection chamber is provided at the front of the main body case. Further, the main body case is provided with a turning wheel on the front lower surface and traveling wheels on both sides of the rear portion so that it can travel on the floor surface. Further, the main body case is provided with a first handle portion that lifts while traveling on the floor surface, and a second handle portion that lifts the rear surface of the main body case in a standing state facing the floor surface.

  The dust sucked together with the air through the hose is captured in a dust bag attached to the dust chamber, and only the air is sucked into the electric blower. In addition, a dust bag filled with dust is opened by rotating the lid to open the upper surface of the dust collection chamber, removing the dust bag from the opening and discarding it together with the dust bag. Install a dust bag in the dust chamber.

However, in the main body of the vacuum cleaner using the dust collection bag, when the dust collection bag is taken out, the dust collection bag must be directly held and discarded, which may cause the hands to become dirty. Therefore, it is conceivable to provide a handle in the dust bag, but it is necessary to provide a handle separately from the main body case, and the structure may be complicated and the size may be increased.
Japanese Patent Publication No.58-1936

  As described above, in the vacuum cleaner described in the above Japanese Patent Publication No. 58-1936, the dust collecting case constituting the main body case must be reversed to discharge the collected dust, which improves workability. I can't figure it out.

  In addition, in a conventional vacuum cleaner equipped with a dust bag, if the handle is provided separately from the main body case to make it easier to dispose of dust, the structure becomes complicated and the main body case becomes larger. There is a risk.

  This invention is made in view of such a point, and it aims at providing the vacuum cleaner which a structure is simplified and size-reduced using the handle part of a dust collector as a handle part of a main body case.

Operate so as to push in against the urging means, rotate the operating parts 77 to disengage the locking claws 82 of the locking arm 81 from the locking recess 28 of the locking part 29 of the case body 2, In this state, the lid 3 is rotated upward by the hinge portions 57, 57, and the upper portion of the dust collection space 58 and the upper portion of the case body 2 are opened. Then, the dust collecting part 9 constituted by attaching the filtering part 97 to which the second filter 108 and the third filter 113 are previously attached to the dust collecting cup 96 is provided with the handle part 98 and the mounting lower concave part 38 of the case body 2. The engaging protrusion 41 of the positioning protrusion 42 of the case body 2 is inserted and engaged with the lower end of the handle portion 98 to be positioned and held on the mounting portion 10.

  Thereafter, the handle 3 is held again, and the lid 3 is rotated so that the lower surface is crimped and covered on the upper surface of the case body 2 and the upper surface of the dust collector 9, and the upper part of the dust collector 9 is covered with the lid 3. The upper upper portion of the handle portion 98 is engaged with the positioning recess 70 of the lid body 3 and is positioned by engaging with the positioning upper recess 59 of the lid 3, and the locking claw portions 82 of the locking portions 75, 75 are locked to the case body 2. The dust collecting portion 9 is attached to the dust collecting space 58 of the main body case 4 by engaging with the recess 28. In this state, the lower end of the suction pipe 63 of the suction portion 61 of the lid 3 is in close contact with the upper end edge of the suction cylinder portion 104 of the filtration portion 97 of the dust collection portion 9 through the airtight member 64 and communicates. The air collecting opening 106 communicates with the through-hole 65 of the lid body 3 in a substantially airtight manner through the frame portion 110 in a state where the frame portion 110 of the filtering portion 97 is in close contact with the lower surface of the mounting upper recess 59 of the lid body 3. That is, the main body suction port 62 of the suction part 61 includes the suction pipe 63 of the suction part 61, the suction cylinder part 104 of the dust collection part 9, the dust collection cup 96, the cylinder collection part 107, the air collection opening 106, the through hole 65, A state of communicating with the intake port of the electric blower 6 through the intake passage 66 and the communication hole 25 is established.

  Then, the connection pipe 123 of the hose 121 is connected to the main body suction port 62 of the suction portion 61, and the suction port main body 129 is appropriately connected via the extension pipe 128 to be in a cleaning standby state. An accessory may be connected instead of the suction port body 129, or an accessory may be connected instead of the extension pipe 128 and the suction port body 129.

  In this cleaning standby state, the electric blower 6 and the electric motor are appropriately driven by the operation of the operating means 126 of the grip portion 124 of the hose 121 to perform cleaning. Note that the control means mounted on the circuit board 20 performs control not to drive the electric blower 6 in order to prevent malfunction when the hose 121 is not connected and is not in a cleaning standby state.

  Then, dust is sucked together with air from a floor suction port (not shown) that opens on the lower surface of the suction port body 129. The sucked dust is sucked from the main body suction port 62 of the suction portion 61 through the extension pipe 128 and the hose 121, passes through the suction pipe 63 of the suction portion 61, and is collected from the suction cylinder portion 104 of the dust collection portion 9. 96 is sucked into a spiral shape in the tangential direction of the inner peripheral surface of the dust collecting cup 96. The dust falls along the inner surface of the dust collection cup 96 due to the centrifugal force of the eddy current of the air sucked in a spiral shape, and the air flows from the center of the vortex flow located on the central axis of the dust collection cup 96 to the dust collecting portion 9. The air flows out from the collecting cylinder portion 107 through the second filter 108 of the filtering portion 97, and air and dust are separated. Further, the separated air is collected through the frame portion 110 by removing fine dust mixed in the air without being separated by the third filter 113 attached to the filtering portion 97 of the dust collecting portion 9. It flows out from the dust part 9. Then, the air flowing out from the dust collecting portion 9 passes through the intake passage 66 from the through hole 65 of the mounting upper recessed portion 59 of the lid 3 that is in close contact with the frame portion 110 of the dust collecting portion 9, and downstream of the intake passage 66. The air is sucked from the intake port of the electric blower 6 through the communication hole 25 of the case body 2 that communicates substantially airtight to the side. Further, the air passes through the electric blower 6 and is exhausted into the electric blower chamber 7 and is further exhausted from the exhaust port 31 to the outside air.

  Also, when cleaning using accessories, remove the inlet body 129 from the extension pipe 128 according to the cleaning location, or remove the extension pipe 128 connected the inlet body 129 from the grip portion 124 of the hose 121, A clearance nozzle 131 attached to an accessory attachment portion 132 of the extension pipe 128 is attached to the tip of the hose 121 or the extension pipe 128 to absorb dust such as furniture gaps or window frame rail grooves. The extension pipe 128 that is removed from the hose 121 and is not used for cleaning is attached by engaging the attachment claw 135 of the attachment means 136 with the attachment recess 146 of the charger 141. When the furniture brush 149 is used, the tip of the gap nozzle 131 is inserted and fitted into the communication pipe portion 163 of the furniture brush 149. When the furniture brush 149 is directly attached to the tip of the hose 121 or the extension pipe 128 for cleaning, the furniture brush 149 is attached to the tip of the hose 121 or the extension pipe 128 so that the communication pipe 163 is fitted. In this state, the flange portion 166 is fitted so as to be in close contact with the distal end of the gripping portion 124 of the hose 121 and the inner peripheral surface of the distal end of the extension tube 128, and the communication tube portion 163 and the gripping portion 124 or the extension tube 128 of the hose 121 are fitted. It closes without generating a gap with the tip of the tube, and efficiently and reliably absorbs dust without leaking.

  Furthermore, the cleaning place is changed, for example, the cleaner body 1 is carried in order to clean the next room, the cleaner body 1 is cleaned in a place where the cleaner body 1 cannot run, such as stairs, or a passenger car, etc. The first handle 86 or the second handle 87, 87 of the handle means 85 or a single unit is mounted integrally when the vehicle is cleaned or carried to the storage location and stored in a predetermined position in the storage location. The cleaner body 1 is lifted by grasping the handle portion 98 of the dust collecting portion 9. Here, since the first handle 86, the second handles 87, 87, and the handle portion 98 are different in axial direction, it is only necessary to select and hold a place that is most easily held by the operator. The dust collecting portion 9 is sandwiched and held by the lid 3 and the case body 2, and the upper portion engages with the mounting upper recess 59 and the lower portion engages with the mounting lower recess 38, and is further positioned. The lower end of 98 is locked to the locking convex portion 41 of the positioning convex portion 42 of the case body 2, and the upper portion of the handle portion 98 is positioned and locked by the positioning concave portion 70 of the case body 2. Therefore, the handle portion 98 of the dust collecting portion 9 can also be used as a handle for lifting the cleaner body 1 like the handle means 85.

  Then, after the electric blower 6 or the electric motor is stopped by the setting operation of the operating means 126 of the grip portion 124 of the hose 121 and cleaning is finished, the locking portions 75 and 75 are operated again to release the locking. The connected state of the lid 3 to the body 2 is released, the lid 3 is rotated to open the upper surface of the dust collecting portion 9 and the upper surface of the case body 2, and the dust collecting portion 9 is held in the case by holding the handle portion 98. Remove from body 2. Thereafter, the filter part 97 is removed from the dust collection cup 96 with the knob part 102, and the dust trapped in the dust collection cup 96 is discharged. Further, the first filter 26, the second filter 108, and the third filter 113 are appropriately removed and washed.

  Next, the extension tube 128 is connected to the charger 141 while the suction inlet body 129 and the hose 121 remain connected by engaging the attachment claw portion 135 of the attachment means 136 of the extension tube 128 with the attachment recess 146 of the charger 141. Attach and place the rear surface of the vacuum cleaner main body 1 into the mounting recess 142 of the charger 141 by insertion engagement. In this state, the charging convex portion 145 of the charger 141 is inserted and engaged with the charging portion 22 of the cleaner main body 1, the cleaner main body 1 is positioned, and the charging terminal of the charging portion 22 is the charging bracket of the charging convex portion 145. The storage battery 18 starts charging. By the start of this charging, the control means of the circuit board 20 of the cleaner body 1 lights up the charging of the display means 89 to display that charging is in progress.

  On the other hand, when the remaining amount of charge of the storage battery 18 decreases due to continued cleaning, the control means of the circuit board 20 turns on the charging notice sign of the display means 89 via the lead wire 90, and the charge decreases to charge. Inform the request. By this notification, the cleaning operator places the cleaner main body 1 on the charger 141 and charges it in the same manner as at the end of cleaning.

  In the above embodiment, the dust collecting space 58 of the main body case 4 is detachably mounted in the intake air passage 118 between the intake side of the electric blower 6 and the main body suction port 62 and sucks in with the air from the main body suction port 62. A handle portion 98 that is exposed from the outer surface of the main body case 4 is provided in the dust collecting portion 9 that captures dust and distributes air to the intake side of the electric blower 6. For this reason, when attaching and detaching the dust collecting part 9 from the main body case 4, the handle part 98 can be easily attached and detached with the handle part 98 and the handle part 98 used for handling the dust collecting part 9 is used as a handle for lifting the main body case 4. For example, when the rear portion of the vacuum cleaner main body 1 is in a standing state facing the floor surface, the handle portion 98 may be gripped without providing the main body case 4 with a handle, and the configuration is simplified and easy. In addition, the manufacturability can be improved, and the method of gripping together with the handle means 85 when the cleaner body 1 is lifted or the like is increased, so that the handleability can be improved.

  The dust collector 9 is connected to the intake side of the electric blower 6 by the case body 2 that houses the electric blower 6 of the main body case 4 and the lid body 3 that is attached to the case body 2 and constitutes the dust collection space 58. Since the main body suction port 62 is clamped and fixed in a state of being communicated in a substantially airtight manner, the dust collecting portion 9 can be securely fixed to the main body case 4 with a simple configuration and can be attached integrally. The handle portion 98 of the dust collecting portion 9 The vacuum cleaner main body 1 can be lifted stably even if it holds.

  In addition, a lower mounting recess 38 is provided in the case body 2 to insert and engage the lower peripheral edge of the dust collecting portion 9, and an upper mounting recess 59 to insert and engage the upper peripheral edge of the dust collecting portion 9 in the lid 3. For this reason, the dust collecting part 9 can be reliably mounted integrally by the main body case 4.

  Further, the case body 2 is provided with a positioning convex portion 42 having a locking convex portion 41 inserted and engaged with the lower end of the handle portion 98 of the dust collecting portion 9, and the upper portion of the handle portion 98 is inserted and engaged with the lid 3. In order to trap and fix the handle 98 by positioning the positioning recess 70, the cylindrical dust collecting cup 96 is used to capture dust by a cyclone system that separates dust by centrifugal force using a vortex flow of the intake air. The formed dust collecting part 9 can be positioned reliably and easily without rotating, and can be positioned using the handle part 98 without providing a separate positioning structure such as a detent, and the apparatus is easily configured with a simple configuration. The dust collection part 9 can be fixed.

  Since the upper and lower portions of the dust collecting portion 9 are covered by the mounting lower recess 38 and the mounting upper recess 59 and the handle portion 98 protrudes forward, the dust collecting cup 96 of the dust collecting portion 9 is separately covered. Therefore, it is not necessary to provide a protective structure, and the size can be easily reduced.

  Further, in order to efficiently separate dust from the vortex by the cyclone method, the dust collecting cup 96 is attached to the main body case 4 with the axial direction in the vertical direction, so that the handle portion 98 is easily provided on the outer periphery of the dust collecting cup 96. Therefore, manufacturability can be improved.

  Further, by arranging the dust collecting cup 96 in a state having an axial direction in the vertical direction, the electric blower 6 is also accommodated in the case body 2 in a state having the axial direction in the vertical direction, and the lid body 3 is used. Since the intake air passage 118 is configured, the configuration for providing the intake air passage 118 is simplified, and the airtightness of each connecting portion of the intake air passage 118 can be easily and reliably ensured, and dust that has been efficiently absorbed can be reduced. Easy to downsize with separable configuration.

  Then, in order to provide the suction portion 61 in the lid body 3 that is an outer shell that can easily obtain rigidity, the hose 121 is pulled during cleaning as compared with the case where the suction portion 61 is provided directly in the dust collection portion 9, for example. Even if a cleaning operation such as running the cleaner body 1 is performed, the suction portion 61 is not damaged and the hose 121 can be connected without being enlarged without fail, so that the handling and cleaning workability can be improved.

  In addition, since the lid 3 covers the dust collection space 58 and the case body 2, the upper portion of the dust collection portion 9 and the upper portion on the intake side of the electric blower 6 are opened by opening and closing the lid body 3. Therefore, the dust collecting unit 9 can be easily attached and detached, and the first filter 26 for preventing the entry of fine dust from the air inlet of the electric blower 6 can be easily provided with a simple configuration. Can be.

  And since the filtration part 97 which covers the upper surface of the dust collection cup 96 is provided in the dust collection part 9, even if it cleans the vacuum cleaner main body 1 in the standing position, it can prevent dust from spilling and dust. The second filter 108 and the third filter 113 can be easily and detachably mounted, and the main body suction port 62 of the suction part 61 of the lid 3 is connected to the suction port of the electric blower 6. Therefore, it is possible to easily form an air passage for improving the manufacturability and to easily reduce the size and weight.

  In addition, since the weight of the dust collector 9, the electric blower 6 and the storage battery 18 is heavy in this order, and the heaviest storage battery 18 is arranged at the approximate center of the main body case 4 located between the dust collector 9 and the electric blower 6, A stable running on the floor surface by the driven wheel 39 and the running wheels 33, 33 is obtained.

  The order of arrangement is such that the suction part 61 to which the hose 121 pulled during cleaning is connected is located at the front part in the traveling direction, from the front side in the traveling direction, the dust collector 9, the storage battery 18, the electric blower 6 so that even if the hose 121 is pulled and cleaned, the lightweight dust collecting portion 9 is located on the front side, so that it is possible to easily change the direction such as turning, and the rear surface is in a standing state facing the floor surface. When placed on the floor, the relatively heavy electric blower 6 is positioned on the lower side, so that it can be stably placed on the floor even in a standing state.

  On the other hand, since the handle means 85 is provided above the center of gravity of the vacuum cleaner body 1 and the second handle 87, 87 is branched from the first handle 86, a place where the operator is most likely to hold is selected and gripped. The main body case 4 can be easily carried stably and the cleaning workability can be improved.

  The handle means 85 is connected to the first handle 86 and the first handle 86 in a state of branching with respect to the first handle 86 substantially symmetrically with the first handle 86 as the axis of symmetry. The hose 121 is connected to the vacuum cleaner main body 1 that is provided in the vacuum cleaner main body 1 with the suction means 61 formed in a substantially Y shape and the first handle 86 is provided with a suction portion 61 on the front side. Since the first handle 86 is located above the center of gravity even when the center of gravity moves to the front side from the position of the center of gravity in the case of the cleaner body 1 alone, the cleaning is performed. Even if the center of gravity moves depending on the form, it can be held at a position above the center of gravity, the cleaner body 1 can be lifted stably, and workability can be improved.

  Furthermore, since the handle means 85 is provided over substantially the entire front-rear direction of the lid body 3, for example, when the rear surface of the cleaner body 1 is in a standing state facing the floor surface, or when the hose 121 is pulled, the cleaner body Even if the front side of the vacuum cleaner main body 1 is lifted up when the 1 is moved, the second handle 87, 87 can be brought into contact with the floor surface to prevent it from falling, and the vacuum cleaner main body can be stably 1 can be placed on the floor surface in an upright position, and the lid 3 can be rotated to easily open and close the upper surface of the dust collecting unit 9 and the upper surface of the case body 2.

  In addition, since the handle means 85 is provided continuously to the suction portion 61, the wiring from the storage battery 18 disposed in the case body 2 is wired inside the handle means 85, and the hose 121 connected to the suction portion 61 is provided. Power can be supplied, and a separate configuration for isolating the wiring portion is not required for installation, and the configuration can be simplified to improve manufacturability and can be easily reduced in size and weight.

  Further, the handle means 85 is provided on the lid body 3 which is rotated to discharge the collected dust and opens the upper surface of the dust collecting portion 9 and the upper surface of the case body 2, so that the lid body 3 is rotated. There is no need to provide a handle separately, the handle means 85 can be used, and the structure can be simplified.

  And since the handle means 85 was continuously formed so that it might extend from the suction part 61 which protruded and formed in the cover body 3, the cover body which forms the intake path 66 which connects the dust collection part 9 to the inlet port of the electric blower 6 3 is provided with locking portions 75 and 75 respectively, and is locked by operating the pair of locking portions 75 and 75 so as to sandwich both sides of the suction portion 61 rising from the lid 3. Is released and the lid 3 can be rotated, so that the operating convex portions 79 and 79 operated in the vicinity of the grip means 85 for gripping the lid 3 to rotate are operated to release the locked state. The operability is improved and the locked state cannot be released by operating only one side. Therefore, the lock parts 75 and 75 are erroneously activated when carrying the vacuum cleaner body 1 with the handle 85. Even if the convex portions 79 and 79 are operated, the locked state is maintained unless both the operating convex portions 79 and 79 are operated. Is released can be prevented lid 3 is rotated. In particular, in the configuration in which the intake passage 66 is provided in the lid 3 as in the cyclone method, both sides can be used effectively, and the size can be easily reduced.

  On the other hand, the communication pipe part 163 of the furniture brush 149 is formed in a substantially elliptical cylindrical shape that fits the tip part of the gap nozzle 131, and when the extension pipe 128 and the tip of the grip part 124 of the hose 121 are fitted to the outer peripheral surface. Since a flange-shaped flange portion 166 that closes between the outer peripheral side of the communication pipe portion 163 and the inner peripheral surface of the extension pipe 128 or the tip of the grip portion 124 of the hose 121 is provided, for example, the state where the gap nozzle 131 is still attached The furniture brush 149 can be attached, and it is not necessary to replace the furniture brush 149 instead of the gap nozzle 131, so that the cleaning workability can be improved, and the grip portion 124 and the extension pipe 128 of the hose 121 are directly used without using the gap nozzle 131. It is possible to prevent the formation of a gap that causes a leak even when connected to the, and to efficiently absorb dust.

  The charger 141 is provided with a mounting recess 146 for locking the mounting claw portion 135 of the mounting means 136 of the extension pipe 128. The leg portions 148 and 148 for preventing the charger 141 from falling are provided with a clearance nozzle 131 and a furniture brush. Since the accessory mounting recesses 150 and 150 for mounting 149 are provided, it is only necessary to attach unnecessary parts to the charger 141 when charging or cleaning, and the vacuum cleaner body 1 is not used for cleaning. The structure for attaching the parts is not necessary, and the vacuum cleaner body 1 that is routed during cleaning can be reduced in size and weight, and the cleaning workability and productivity can be improved. Furthermore, since the accessory mounting recesses 150 and 150 are provided in the leg portions 148 and 148 for preventing the charger 141 from falling, the configuration of the charger 141 can be reduced in size.
