Fig. 6 is still another cross-sectional view of the handle holding mechanism of the electric vacuum cleaner according to the embodiment of the present invention. - Embodiments of an electric vacuum cleaner according to the present invention will be described by referring to
Fig. 1 to Fig. 6 . -
Fig. 1 andFig. 2 are perspective views of a station and an electric vacuum cleaner according to the embodiment of the present invention. - As shown in
Fig. 1 andFig. 2 , theelectric vacuum cleaner 1 according to the present embodiment can be connected to and stored in a station 2 (Fig. 1 ), and also can be used in the state of being separated from the station 2 (Fig. 2 ). -
Fig. 1 shows a configuration in which theelectric vacuum cleaner 1 is connected to the station 2. This configuration is called a storage configuration of theelectric vacuum cleaner 1.Fig. 2 shows a configuration in which theelectric vacuum cleaner 1 is disconnected from the station 2. This configuration is called a use configuration of theelectric vacuum cleaner 1. - The
electric vacuum cleaner 1 is a so-called cordless type. Although theelectric vacuum cleaner 1 is a so-called canister type, the electric vacuum cleaner 3 is not limited to this type but may be configured as an upright type, a stick type, or a handy type. - The station 2 has a function of charging the
electric vacuum cleaner 1, a function of collecting the dust collected using theelectric vacuum cleaner 1, and a function of accumulating the collected dust. The station 2 is placed at an arbitrary place in a room. - A user separates the
cleaner body 7 of theelectric vacuum cleaner 1 from the station 2 (Fig. 2 ), and cleans the surface to be cleaned by running theelectric vacuum cleaner 1 on the surface to be cleaned or by holding theelectric vacuum cleaner 1 when moving in the room. Afterward, the user returns (connects) thecleaner body 7 to the station 2 and stores it (Fig. 1 ). When thecleaner body 7 is connected to the station 2, the station 2 charges thecleaner body 7 while collecting the dust accumulated inside theelectric vacuum cleaner 1 in a timely manner. That is, every time theelectric vacuum cleaner 1 is connected to the station 2 after being used for cleaning, the station 2 collects the dust collected by theelectric vacuum cleaner 1 so as to empty theelectric vacuum cleaner 1. - The frequency of collecting the dust from the
electric vacuum cleaner 1 to the station 2 may not be each time theelectric vacuum cleaner 1 is connected to the station 2. The station 2 may collect dust from theelectric vacuum cleaner 1 every plural number of times theelectric vacuum cleaner 1 is connected to the station 2. For example, the station 2 may collect dust from theelectric vacuum cleaner 1 once a week on the premise thatelectric vacuum cleaner 1 is used once a day, i.e., the station 2 may collect dust from theelectric vacuum cleaner 1 every seven times of the use of theelectric vacuum cleaner 1. - The electric vacuum cleaner includes: the
cleaner body 7 that can travel on the surface to be cleaned; and atubular part 8 that is attachable to and detachable from thecleaner body 7. Thetubular part 8 is fluidly connected to thecleaner body 7. - The
cleaner body 7 includes: abody housing 11; a pair ofwheels 12 provided on the respective right and left sides of thebody housing 11; aprimary dust container 13 detachably attached to thebody housing 11; ahandle 14 provided on thebody housing 11; a primaryelectric blower 15 accommodated in thebody housing 11; acleaner controller 16 mainly for controlling the primaryelectric blower 15, and arechargeable battery 17 for storing power to be supplied to the primaryelectric blower 15. - The
cleaner body 7 drives the primaryelectric blower 15 by the power stored in therechargeable battery 17. Thecleaner body 7 acts negative pressure to be generated using the primaryelectric blower 15 to thetubular part 8. Theelectric vacuum cleaner 1 sucks on dust-containing air from the surface to be cleaned through thetubular part 8, separates dust from the dust-containing air, collects and accumulates the dust after separation, and exhausts the dust-removed clean air. - In the front of the
body housing 11, aconnection port 18 is provided as a suction port of thecleaner body 7. Theconnection port 18 is a coupling joint to which thetubular part 8 can be attached, and from which thetubular part 8 can be detached. Theconnection port 18 fluidly connects thetubular part 8 to theprimary dust container 13. Theconnection port 18 may be provided at a portion other than the front portion of thebody housing 11, for example, may be provided on the side face or the top face of thebody housing 11. - The
cleaner body 7 according to the present embodiment is connected to the station 2 in a position in which the front of thebody housing 11 is directed upward. This position in which the front of thebody housing 11 is directed upward is referred to as a storage position of thecleaner body 7 or a storage position of theelectric vacuum cleaner 1. Thecleaner body 7 is connected to the station 2 by being lowered down from above. Thecleaner body 7 connected to the station is detached from the station 2 by being lifted up (elevated). The position in which theconnection port 18 is directed upward is also referred to as a standing position of thecleaner body 7. - In the use configuration of the
electric vacuum cleaner 1, thecleaner body 7 is directed such that the front of the body housing 11 faces the traveling direction, i.e., the forward direction. Such a position in which thecleaner body 7 can move on the cleaning target region by traveling on the surface to be cleaned is referred to as a use position (Fig. 2 ) of thecleaner body 7. Thecleaner body 7 in the use position grounds thewheels 12 on the surface to be cleaned, and supports thebody housing 11 such thatbody housing 11 can travel. - The
wheels 12 support thecleaner body 7 such that thecleaner body 7 can travel. Thecleaner body 7 is supported by casters (not shown) in addition to the pair ofwheels 12. - The
primary dust container 13 accumulates the dust to be sucked into theelectric vacuum cleaner 1. Theprimary dust container 13 separates, collects, and accumulates the dust from the dust-containing air flowing into thecleaner body 7 while sending the dust-removed clean air to the primaryelectric blower 15. - The
handle 14 is used when a user carries thecleaner body 7. Thehandle 14 is arched in the width direction of thebody housing 11. - The primary
electric blower 15 sucks in air from theprimary dust container 13 so as to generate negative pressure (i.e., suction vacuum pressure). - The
cleaner controller 16 includes a microprocessor (not shown) and a storage device (not shown) for storing, for example, parameters and various operation programs to be executed by the microprocessor. The storage device stores various settings (arguments) related to a plurality of preset operation modes. The operation modes are related to the output of the primaryelectric blower 15. Different input values (i.e., input values of the primaryelectric blower 15 and current values flowing to the primary electric blower 15) are set for each operation mode. Each operation mode is associated with an input received using thetubular part 8. Thecleaner controller 16 alternatively selects an arbitrary operation mode corresponding to the input received using thetubular part 8 from the preset operation modes, and reads out the selected operation mode from the storage device so as to drive the primaryelectric blower 15 on the basis of the settings of the operation mode having been read out. - The
rechargeable battery 17 supplies power to the primaryelectric blower 15 and thecleaner controller 16. Therechargeable battery 17 is electrically connected to a pair of chargingelectrodes 19 provided on thecleaner body 7. - The
tubular part 8 sucks in dust-containing air from the surface to be cleaned by the negative pressure that acts from thecleaner body 7, and leads the dust-containing air to thecleaner body 7. Thetubular part 8 is provided with: a connectingtube 21 detachably connected as a joint to thecleaner body 7; adust collecting hose 22 fluidly connected to the connectingtube 21; ahand operation tube 23 fluidly connected to thedust collecting hose 22; agrip 25 protruding from thehand operation tube 23; aninput unit 26 provided on thegrip 25; anextension tube 27 detachably connected to thehand operation tube 23; and acleaner head 28 detachably connected to theextension tube 27. - The connecting
tube 21 is a joint detachable from theconnection port 18. The connectingtube 21 is fluidly connected to theprimary dust container 13 through theconnection port 18. - The
dust collecting hose 22 is a long, flexible, and substantially cylindrical hose. One end (i.e., the rear end in this case) of thedust collecting hose 22 is fluidly connected to the connectingtube 21. Thedust collecting hose 22 is fluidly connected to theprimary dust container 13 through the connectingtube 21. - The
hand operation tube 23 relays thedust collecting hose 22 and theextension tube 27. One end (i.e., the rear end in this case) of thehand operation tube 23 is fluidly connected to the other end (i.e., the front end in this case) of thedust collecting hose 22. Thehand operation tube 23 is fluidly connected to theprimary dust container 13 through thedust collecting hose 22 and the connectingtube 21. - The
grip 25 is a portion to be gripped by a user's hand for operating theelectric vacuum cleaner 1. Thegrip 25 protrudes from thehand operation tube 23 in an appropriate shape that can be readily grasped by the user's hand. - The
input unit 26 includes switches corresponding to the respective operation modes. For example, theinput unit 26 includes: astop switch 26a corresponding to the operation of stopping the primaryelectric blower 15; astart switch 26b corresponding to the operation of starting the primaryelectric blower 15; and abrush switch 26c corresponding to power supply to thecleaner head 28. Thestop switch 26a and thestart switch 26b are electrically connected to thecleaner controller 16. A user of theelectric vacuum cleaner 1 can operate theinput unit 26 to alternatively select one of the operation modes of the primaryelectric blower 15. Thestart switch 26b also functions as a selecting switch of the operation modes during operation of the primaryelectric blower 15. Each time thecleaner controller 16 receives an operation signal from thestart switch 26b, thecleaner controller 16 switches the operation mode in order of strong → medium → weak → strong → medium → weak → .... Instead of thestart switch 26b, theinput unit 26 may be individually provided with a strong operation switch (not shown), a medium operation switch (not shown), and a weak operation switch (not shown). - The
extension tube 27 has a telescopic structure in which a plurality of tubular bodies are overlaid, and is expandable and contractable. A joint structure is provided at one end (i.e., the rear end in this case) of theextension tube 27, and this joint structure is attachable to and detachable from the other end (i.e., the front end in this case) of thehand operation tube 23. Theextension tube 27 is fluidly connected to theprimary dust container 13 through thehand operation tube 23, thedust collecting hose 22, and the connectingtube 21. - The
cleaner head 28 can run or slide on the surface to be cleaned such as a wooden floor and a carpet, and includes asuction port 31 on its bottom face opposed to the surface to be cleaned in a running state or a sliding state. In addition, thecleaner head 28 includes: a rotatable brushbar (roller brushbar, rotatable brush, brush roller) 32 disposed at thesuction port 31; and anelectric motor 33 for driving thebrushbar 32. A joint structure is provided on one end (i.e., the rear end in this case) of thecleaner head 28, and this joint structure is attachable to and detachable from the other end (i.e., the front end in this case) of theextension tube 27. Thecleaner head 28 is fluidly connected to theprimary dust container 13 through theextension tube 27, thehand operation tube 23, thedust collecting hose 22, and the connectingtube 21. That is, thecleaner head 28, theextension tube 27, thehand operation tube 23, thedust collecting hose 22, the connectingtube 21, and theprimary dust container 13 is a suction-air passage from thesuction port 31 to the primaryelectric blower 15. Each time theelectric motor 33 receives the operation signal from thebrush switch 26c, theelectric motor 33 alternately repeats the operation start and the operation stop. - When the
start switch 26b is operated, theelectric vacuum cleaner 1 starts up the primaryelectric blower 15. For example, when thestart switch 26b is operated in the state where the primaryelectric blower 15 is stopped, first, theelectric vacuum cleaner 1 starts the primaryelectric blower 15 in the strong operation mode. When thestart switch 26b is operated again in the strong operation mode, theelectric vacuum cleaner 1 drives the primaryelectric blower 15 in the medium operation mode. When thestart switch 26b is operated three times, the electric vacuum cleaner 3 drives the primaryelectric blower 15 in the weak operation mode. In this manner, every time thestart switch 26b is operated, the above-described mode switching is repeated. The strong operation mode, the medium operation mode, and the weak operation mode are predetermined operation modes. The input value to be set for the strong operation mode is the largest, and the input value to be set for the weak operation mode is the smallest. The primaryelectric blower 15 having started up sucks in air from theprimary dust container 13 so as to reduce the pressure inside of theprimary dust container 13 into a negative pressure. - The negative pressure inside the
primary dust container 13 passes sequentially through theconnection port 18, the connectingtube 21, thedust collecting hose 22, thehand operation tube 23, theextension tube 27, and thecleaner head 28 so as to act on thesuction port 31. Theelectric vacuum cleaner 1 sucks in the dust on the surface to be cleaned together with the air using the negative pressure acting on thesuction port 31. Theprimary dust container 13 separates, collects, and accumulates the dust from the inhaled dust-containing air, and sends the air having been separated from the dust-containing air to the primaryelectric blower 15. The primaryelectric blower 15 discharges the air sucked in from theprimary dust container 13 to the outside of thecleaner body 7. - The station 2 is installed at an arbitrary place on the surface to be cleaned. The station 2 includes a
platform 41 connectable to thecleaner body 7, and adust collection part 42 integrally provided with theplatform 41. The station 2 further includes adust transfer tube 43 to be connected to theprimary dust container 13 of theelectric vacuum cleaner 1 in the storage configuration of theelectric vacuum cleaner 1. - The
platform 41 has substantially the same width dimension as that of thedust collection part 42, and protrudes to the front of thedust collection part 42 so as to spread in a rectangular shape. Theplatform 41 has a shape and size that can accommodate thecleaner body 7 of theelectric vacuum cleaner 1 in plan view. - The
platform 41 has chargingterminals 45 connectable to thecleaner body 7. When theelectric vacuum cleaner 1 is connected to the station 2, the chargingterminals 45 contact the chargingelectrodes 19 of thecleaner body 7 and are electrically connected to the chargingelectrodes 19. - The
platform 41 has abulge 46 that is disposed to be close to and along the side face of thecleaner body 7 in the storage configuration of theelectric vacuum cleaner 1. - The
dust collection part 42 is disposed behind theplatform 41. Thedust collection part 42 is a box formed in an appropriate shape such that thedust collection part 42 can be placed on the surface to be cleaned integrally with theplatform 41. Thedust collection part 42 extends upward above theplatform 41. Thedust collection part 42 has an appropriate shape that does not interfere with thecleaner body 7 connected to theplatform 41. - The
dust collection part 42 includes: ahousing 47; asecondary dust container 48 that collects the dust to be discharged from theprimary dust container 13 through thedust transfer tube 43 and accumulates the collected dust; a secondaryelectric blower 49 accommodated in thedust collection part 42 and fluidly connected to thesecondary dust container 48; astation controller 51 mainly for controlling the secondaryelectric blower 49; and apower cord 52 for feeding power from a commercial AC power supply to thedust collection part 42. - The top plate of the
platform 41 and thehousing 48 is an integral molding of resin. - The
secondary dust container 48 is fluidly connected to thedust transfer tube 43. Thesecondary dust container 48 separates, collects, and accumulates the dust from the dust-containing air flowing fromdust transfer tube 43, and sends the dust-removed clean air to the secondaryelectric blower 49. Thesecondary dust container 48 is detachably mounted on the left side (i.e., right side as viewed from the front) of thedust collection part 42 and exposed to the appearance of the station 2. - The secondary
electric blower 49 sucks in air from thesecondary dust container 48 so as to generate negative pressure (i.e., suction vacuum pressure), and transfers the dust from theprimary dust container 13 to thesecondary dust container 48. The secondaryelectric blower 49 is accommodated in the right side (i.e., left part as viewed from the front) of thedust collection part 42. - The
station controller 51 includes: a microprocessor (not shown); and a storage device (not shown) for storing, for example, parameters and various operation programs to be executed using the microprocessor. Thestation controller 51 executes drivability control of the secondaryelectric blower 49 and charge control of therechargeable battery 17 of theelectric vacuum cleaner 1. - The
dust transfer tube 43 is connected to theprimary dust container 13 in the storage configuration of theelectric vacuum cleaner 1. Thedust transfer tube 43 is an air passage for transferring the dust collected using theelectric vacuum cleaner 1 to thesecondary dust container 48. When theelectric vacuum cleaner 1 is connected to the station 2, thedust transfer tube 43 is connected to theprimary dust container 13 and fluidly connects theprimary dust container 13 to thesecondary dust container 48. - The
dust transfer tube 43 is connected to the suction side of thesecondary dust container 48. The negative pressure to be generated using the secondaryelectric blower 49 acts on thedust transfer tube 43 through thesecondary dust container 48. - The
dust transfer tube 43 includes: an inlet connected to theprimary dust container 13 of theelectric vacuum cleaner 1; and an outlet connected to thesecondary dust container 48. Thedust transfer tube 43 extends rearward from the inlet disposed at theplatform 41 so as to reach the inside of thedust collection part 42, and bends and extends upward inside thedust collection part 42 so as to reach the outlet disposed at the side of thesecondary dust container 48. - The charging
terminals 45 and the inlet of thedust transfer tube 43 are provided on theplatform 41 side by side. - When the
electric vacuum cleaner 1 is connected to (i.e., returned to) the station 2, the chargingelectrodes 19 of theelectric vacuum cleaner 1 are electrically connected to thecharging terminals 45 of the station 2 and thedust transfer tube 43 of the station 2 is connected to theprimary dust container 13. Thereafter, the station 2 starts charging therechargeable battery 17 of theelectric vacuum cleaner 1. Additionally, the station 2 starts the secondaryelectric blower 49 in a timely manner. The secondaryelectric blower 49 having been started up sucks in air from thesecondary dust container 48 and reduces the pressure inside of thesecondary dust container 48 into a negative pressure. - The negative pressure inside the
secondary dust container 48 acts on theprimary dust container 13 through thedust transfer tube 43. The station 2 sucks in the dust accumulated in theprimary dust container 13 together with air using the negative pressure acting on theprimary dust container 13. Thesecondary dust container 48 separates, collects, and accumulates the dust from the sucked air, and sends the dust-separated air to the secondaryelectric blower 49. The secondaryelectric blower 49 discharges the clean air sucked from thesecondary dust container 48 to the outside of the station 2. - Note that the station 2 may be a simple stand that does not have the charging function of the
rechargeable battery 17 or the function of collecting dust from theprimary dust container 13. In addition, the station 2 may be a charging stand having only the charging function of therechargeable battery 17. Further, the station 2 may be a dust station having only the function of collecting dust from theprimary dust container 13. - Next, the
handle 14 of thecleaner body 7 according to the embodiment of the present invention will be described. -
Fig. 3 is a perspective view illustrating the state where the handle of the electric vacuum cleaner according to the embodiment of the present invention is pulled out. - As shown in
Fig. 3 , thecleaner body 7 of theelectric vacuum cleaner 1 according to the present embodiment includes the pair ofwheels 12. - The
respective wheels 12 are disposed at the right and left ends of the rear half of the cylindrical structure of thebody housing 11 so as to be concentric with the rear half of the cylindrical structure of thebody housing 11. The diameter of eachwheel 12 is larger than the height of thebody housing 11 in the vertical direction (this height corresponds to the diameter of the rear half of the cylindrical structure). In the side view of thecleaner body 7, i.e., when viewed from the direction of the rotation centerline of thewheels 12, thewheels 12 cover the rear end of thebody housing 11. Thus, even when thecleaner body 7 is in a state where thebody housing 11 is turned upside down (i.e., front and rear of thehousing 11 is inverted), thecleaner body 7 can ground thewheels 12 on the surface to be cleaned. Thebody housing 11 can be turned upside down (i.e., front and rear of thehousing 11 can be inverted) around the rotation centerline of eachwheel 12 without causing its rear end to interfere with the surface to be cleaned. Thecleaner body 7 is provided with a first auxiliary wheel (not shown) that supports thecleaner body 7 in cooperation with thewheels 12 when the front side (top side) of thecleaner body 7 is directed upward. The connectingtube 21 is provided with a second auxiliary wheel (not shown) that supports thecleaner body 7 in cooperation with thewheels 1 when the rear side (bottom side) of thecleaner body 7 is directed upward. -
Fig. 3 shows thecleaner body 7 in the position in which the front side (rear side) faces upward. - The
cleaner body 7 includes: thebody housing 11 having ahandle storage recess 11a; thehandle 14 that is provided on thebody housing 11 and can be moved between the storage position (Fig. 2 ) where it has entered thehandle storage recess 11a and the use position (Fig. 3 ) where it has come out of thehandle storage recess 11a; and a handle holding mechanism 61 that holds thehandle 14 being in the storage position in thehandle storage recess 11a. - The
handle storage recess 11a is provided at the front edge of the top side of thebody housing 11. Thehandle storage recess 11a extends so as to follow the shape of the front edge of the top side of thebody housing 11. - In the use position (i.e., recumbent position) of the
cleaner body 7, the use position in which thehandle storage recess 11a of thebody housing 11 is directed upward is referred to as the first use position (i.e., prone position or face-down position). The use position in which thehandle storage recess 11a of thebody housing 11 is directed downward is referred to as the second use position (i.e., inverted position, supine position, or face-up position). In the first use position, thecleaner body 7 supports thebody housing 11 using thewheels 12 and first auxiliary wheel (not shown) with the top side (top face) of thebody housing 11 directed upward. In the second use position, thecleaner body 7 supports thebody housing 11 using thewheels 12 and second auxiliary wheel (not shown) with the bottom side (bottom face) of thebody housing 11 directed upward. - The
handle 14 is bridged between the right and leftwheels 12 in an arch. When thehandle 14 is not in use, thehandle 14 is housed in thehandle storage recess 11a of the body housing 11 (storage state of thehandle 14 as shown inFig. 2 ). When being used, thehandle 14 is pulled out of thehandle storage recess 11a (the use state of thehandle 14 as shown inFig. 3 ). - The
handle 14 is swingably provided on thebody housing 11. The swinging centerline of thehandle 14 extends in the width direction (right-left direction) of thebody housing 11 or thecleaner body 7. In other words, thehandle 14 moves around the swinging centerline extending in the width direction of thebody housing 11 so as to be pulled and raised from thehandle storage recess 11a. - The shape of the
handle 14 matches the shape of the front edge of the arcuate front half of thebody housing 11. Thehandle 14 reaches the rear end of thecleaner body 7 when being pulled out most. - In the first use position in which the
cleaner body 7 is placed on the horizontal plane and thehandle storage recess 11a is directed upward, thehandle 14 can be moved to the rear of thecleaner body 7 substantially passing directly above thecleaner body 7. - The
handle 14 may be provided so as to be linearly movable in the direction of approaching or moving away from thebody housing 11, for example, in the vertical direction in the first use position (i.e., the direction of passing through the top side and the bottom side or the direction of passing through the top face and the bottom face). In other words, thehandle 14 may slide in the direction of approaching or moving away from thebody housing 11. In this case, thehandle 14 is pulled out of or enters thehandle storage recess 11a. - In the storage configuration of the
electric vacuum cleaner 1, thecleaner body 7 takes the storage position (standing position). In the use configuration of theelectric vacuum cleaner 1, thecleaner body 7 turns over from the first use position with thehandle storage recess 11a directed upward to the second use position with thehandle storage recess 11a directed downward through the standing position, and turns over from the second use position to the first use position through the standing position. Such behavior (position change) of thecleaner body 7 may cause thehandle 14 to be released from or housed in thehandle storage recess 11a if no restraining force is applied to thehandle 14. Under the assumption that no restraining force is applied to thehandle 14, for example, in the case of changing the position of thecleaner body 7 from the first use position with thehandle storage recess 11a directed upward to the standing position, thehandle 14 is released from thehandle storage recess 11a so as to hang on the top side of thecleaner body 7 due to its own weight and the inertia force caused by this position change and thereby hinders the movement or running of thecleaner body 7. Under the assumption that no restraining force is applied to thehandle 14, when thecleaner body 7 is stored in the station 2 in the standing position (Fig. 1 ), thehandle 14 is released from thehandle storage recess 11a by its own weight and hangs down on the top side of thecleaner body 7 so as to impair the appearance of theelectric vacuum cleaner 1. Further, under the assumption that no restraining force is applied to thehandle 14 in the second use position (inverted position) with thehandle storage recess 11a directed downward, thehandle 14 is released from thehandle storage recess 11a so as to hang down toward the surface to be cleaned and thereby hinders the movement or running of thecleaner body 7. For example, if thehandle 14 hangs down (like bowing) in the traveling direction (i.e., forward direction) in the second use position (i.e., inverted position), there is a possibility that thehandle 14 collides so as to hit a step in the traveling direction. If thehandle 14 hits a step in the traveling direction, thecleaner body 7 is naturally obstructed from running. - For this reason, the
cleaner body 7 includes the handle holding mechanism 61. When thebody housing 11 is in the standing position, the handle holding mechanism 61 holds thehandle 14 being in the storage position in thehandle storage recess 11a. In addition, when thebody housing 11 is in the inverted position, the handle holding mechanism 61 holds thehandle 14 being in the storage position in thehandle storage recess 11a. Further, when thebody housing 11 is in the middle position between the standing position and the inverted position, the handle holding mechanism 61 holds thehandle 14 being in the storage position in thehandle storage recess 11a. - The handle holding mechanism 61 includes: an elastic member 62 that generates force to move the
handle 14 from the use position to the storage position; concave-convex portions 63 that are provided on thehandle 14 and thehandle storage recess 11a so as to be interdigitated with each other; and a hook mechanism 64 that swings by its own weight so as to be hooked on thehandle 14 before thehandle 14 comes out of thehandle storage recess 11a by its own weight. -
Fig. 4 to Fig. 6 are cross-sectional views of the handle holding mechanism of the electric vacuum cleaner according to the embodiment of the present invention. - As shown in
Fig. 4 to Fig. 6 , the handle holding mechanism 61 of theelectric vacuum cleaner 1 according to the present embodiment includes the concave-convex portions 63 and the hook mechanism 64 in addition to the elastic member 62. -
Fig. 4 illustrates the relationship between the handle holding mechanism 61 and thehandle 14 of thecleaner body 7 in the first use position.Fig. 5 illustrates the relationship between the handle holding mechanism 61 and thehandle 14 of thecleaner body 7 in the standing position.Fig. 6 illustrates the relationship between the handle holding mechanism 61 and thehandle 14 of thecleaner body 7 in the second use position. - The
handle 14 is swingably supported by thebody housing 11 of thecleaner body 7 via ahandle shaft 14a. - The elastic member 62 is, for example, a torsion spring. When the
handle 14 comes out from the storage position and moves to the use position, the elastic member 62 deforms due to this movement so as to store elastic energy. When the force acting on the handle 14 (i.e., force for moving thehandle 14 from the storage position to the use position) decreases or is lost, the elastic member 62 consumes the stored elastic energy so as to generate the force to move thehandle 14 from the use position to the storage position. - The elastic member 62 may be provided directly on the
handle shaft 14a that is provided so as to match the swinging centerline of thehandle 14. Additionally or alternatively, the elastic member 62 may indirectly transfer the power to and from thehandle 14 via thepower transmission mechanism 66. Thepower transmission mechanism 66 is, for example, a cam mechanism, a link mechanism, or a speed reduction mechanism in which a plurality of gears (not shown) are meshed. The elastic member 62 may be a coil spring or a rubber elastic body depending on thepower transmission mechanism 66. - One of the concave-convex portions 63 is provided in the
handle storage recess 11a, and the other of the concave-convex portions 63 is provided in thehandle 14. The concave-convex portions 63 according to the present embodiment include: aconvex member 67 provided on thehandle storage recess 11a; and aconcave member 68 provided on thehandle 14. When thehandle 14 enters thehandle storage recess 11a and reaches the storage position, theconcave member 68 and theconvex member 67 interdigitate with each other so as to hinder the movement of thehandle 14. One of the concave-convex portions 63, for example, theconvex member 67 may be provided so as to be able to approach and move away from theconcave member 68. In this case, for example, it is preferred that the handle holding mechanism 61 includes a coil spring (not shown) for generating spring force in the direction in which theconvex member 67 is interdigitated with theconcave member 68. In other words, theconvex member 67 is provided so as to be able to protrude and retract from the inner wall face of thehandle storage recess 11a. It is preferred that the protruding and retracting direction of theconvex member 67 intersects the moving direction of thehandle 14. - The hook mechanism 64 is provided in the
handle storage recess 11a. Thehandle storage recess 11a is provided with abase 69 for supporting the hook mechanism 64. Thehandle 14 includes ahook receiver 71 that is hooked the hook mechanism 64. The hook mechanism 64 is provided so as to be movable and constantly hangs down with its hook opened upward by its own weight. On the one hand, the hook mechanism 64 can hook on thehook receiver 71; on the other hand, when thecleaner body 7 is in the first use position, the hook mechanism 64 hangs down to unhook or moved away from thehook receiver 71 due to its own weight. Further, the hook mechanism 64 is hooked on thehook receiver 71 in the process in which thecleaner body 7 moves from the first use position to the standing position. When the hook mechanism 64 hooks on thehook receiver 71, thehandle 14 is held in thehandle storage recess 11a. Further, when thecleaner body 7 is in the process of moving from the standing position to the second use position and when thecleaner body 7 is in the second use position, the hook mechanism 64 maintains the state of hooking on thehook receiver 71. The hook mechanism 64 is supported by thebase 69 and can rotate at least 180 degrees about thehook receiver 71. InFig. 4 to Fig. 6 , the gravitational acceleration acting on the hook mechanism 64 is indicated by the solid arrow G. - The hook mechanism 64 may include a
weight 72 for increasing its own weight. Further, the hook mechanism 64 may have a hook shape of a so-called fishhook. In this case, the hook mechanism 64 may be provided with a plurality of hooks that includes: a first hook (not shown) for holding thehandle 14 in the standing position; and a second hook (not shown) for holding thehandle 14 in the inverted position. - It is sufficient that the handle holding mechanism 61 includes at least one of the elastic member 62, the concave-convex portions 63, and the hook mechanism 64. When the
handle 14 can be held in thehandle storage recess 11a against the weight ofhandle 14, it is not required that the handle holding mechanism 61 includes all of the elastic member 62, the concave-convex portions 63, and the hook mechanism 64, but it is sufficient that the handle holding mechanism 61 includes any one of them (62, 63, and 64) or a combination of two or more of them (62, 63, and 64). - As described above, the
electric vacuum cleaner 1 according to the present embodiment includes the handle holding mechanism 61 that holds thehandle 14 being in the storage position in thehandle storage recess 11a. Consequently, even if thecleaner body 7 is erected (standing position) or is used upside down (i.e., used in the inverted position), theelectric vacuum cleaner 1 can prevent thehandle 14 from being released from thehandle storage recess 11a. That is, in theelectric vacuum cleaner 1, thehandle 14 neither hinders storage by hanging down nor hinders running by being caught on a step on the surface to be cleaned. - In addition, the
electric vacuum cleaner 1 according to the present embodiment includes the elastic member 62 that generates force to move thehandle 14 to the storage position. Consequently, when storing thehandle 14, theelectric vacuum cleaner 1 can automatically store thehandle 14 by the restoring force of the elastic member 62 without intentionally moving thehandle 14 to thehandle storage recess 11a. - Further, the
electric vacuum cleaner 1 according to the present embodiment includes the concave-convex portions 63 that are provided in thehandle 14 and thehandle storage recess 11a so as to be interdigitated with each other. The concave-convex portions 63 prevents thehandle 14 from being released from thehandle storage recess 11a by its simple structure. In other words, in theelectric vacuum cleaner 1, thehandle 14 does not hang down so as to hinder storage or running. - Moreover, the
electric vacuum cleaner 1 according to the present embodiment can dispose any one of theconcave member 68 and theconvex member 67 in thehandle storage recess 11a and can dispose the other in thehandle 14. Consequently, theelectric vacuum cleaner 1 can improve the holding force of thehandle 14 without impairing manufacturability. - Furthermore, the
electric vacuum cleaner 1 according to the present embodiment includes the hook mechanism 64 that moves by its own weight so as to be hooked on thehandle 14. Consequently, theelectric vacuum cleaner 1 can reliably hold thehandle 14 depending on the position change of thecleaner body 7. In other words, in theelectric vacuum cleaner 1, thehandle 14 neither obstructs storage nor hinders running by hanging down. - As described above, according to the
electric vacuum cleaner 1 of the present embodiment, even if thecleaner body 7 is set in the standing position or is used in the inverted position, themovable handle 14 can be stored at a non-problematic position. - While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions. Indeed, the novel embodiments described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions and changes in the form of the embodiments described herein may be made without departing from the spirit of the inventions. The accompanying claims and their equivalents are intended to cover such forms or modifications as would fall within the scope and spirit of the inventions.
