Description

  The present embodiment relates to a vacuum cleaner.

  A general vacuum cleaner has a structure in which a fan motor is arranged on the downstream side of a dust collecting portion formed in a main body casing. When the fan motor is driven, negative pressure is generated in the main body casing, and dust is sucked by the negative pressure and collected in the dust collecting portion. The collected dust has a structure that can be taken out by opening and closing a lid provided in the dust collecting portion.

  In a vacuum cleaner that can be cleaned and carried with a handle, the position of the dust collecting unit is restricted to avoid interference with the handle, and the position of the fan motor is also restricted accordingly. Patent Document 1 describes a portable vacuum cleaner in which a dust collecting portion is formed at a position where the lid can be opened and closed while avoiding interference with the handle.

JP 2000-139782 A

  However, according to the conventional vacuum cleaner, an appropriate balance of the center of gravity cannot be obtained depending on the relative positional relationship between the handle and the fan motor, making it difficult to handle during cleaning and carrying. For example, according to the vacuum cleaner described in Patent Document 1, since the fan motor is directly connected to the rear of the dust collecting portion, the fan motor is disposed directly under the handle, and the entire center of gravity is shifted toward the front. Therefore, it feels more than the actual weight during cleaning and carrying, making handling difficult.

  Therefore, an object of the present embodiment is to provide a cleaner capable of optimizing the balance of the center of gravity and improving operability.

  According to one aspect of the present embodiment, a casing, a handle provided outside the casing, a fan motor provided in the casing, and a cylindrical duct component provided in the casing, A dust collecting portion formed in the casing, wherein the dust collecting portion, the duct constituent member, and the fan motor are sequentially arranged, and the duct constituent member has one end of the dust collecting portion. A vacuum cleaner is provided which is connected to the opening and whose other end is connected to the suction port of the fan motor, and which allows the dust collecting part and the fan motor to communicate with each other.

  According to the present embodiment, it is possible to provide a cleaner capable of optimizing the center of gravity balance and improving operability.

In the following description of the drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic, and the relationship between the thickness and the planar dimensions, the ratio of the thickness of each layer, and the like are different from the actual ones. Therefore, specific thicknesses and dimensions should be determined in consideration of the following description. Moreover, it is a matter of course that portions having different dimensional relationships and ratios are included between the drawings.

  Further, the embodiments described below exemplify apparatuses and methods for embodying the technical idea of the present invention, and the embodiments of the present invention include the material, shape, structure, The layout is not specified as follows. Various modifications can be made to the embodiment of the present invention within the scope of the claims.

[appearance]
Drawing 1 is an outline view of cleaner 1 concerning an embodiment, (a) is a front view, (b) is a left view, and (c) is a rear view. The vacuum cleaner 1 is a so-called stick-type (vertical) slim vacuum cleaner. The outer surface is formed into a curved surface as a whole in consideration of improvement in the feel of the user and design.

  Specifically, as shown in FIG. 1, an elongated extension pipe 3 is attached to an opening of a substantially cylindrical main body 2 that houses an electric blower, and a relatively wide suction head 4 is rotatable at the tip thereof. It is attached. If the extension pipe 3 is removed from the main body 2, it can be used as a so-called handy cleaner. When used as a handy cleaner, the brush B can be attached to the opening of the main body 2 instead of the extension pipe 3.

  In use, the power cable C (only part of which is shown) drawn from the main body 2 is connected to a power outlet. If such a wired AC power supply type is adopted, it is not necessary to mount a rechargeable battery in the vacuum cleaner 1. Therefore, it is possible to realize a strong suction force while being compact and lightweight compared to a cordless type vacuum cleaner equipped with a rechargeable battery.

  Hereinafter, as shown in FIG. 1, the side on which the suction head 4 is present is referred to as “front side”, and the side on which the main body 2 is present is referred to as “rear side”. In accordance with the posture depicted in the drawing, the side on which the suction head 4 exists may be referred to as “lower side”, and the side on which the main body 2 exists may be referred to as “upper side”. The “left-right direction” is considered based on the user of the vacuum cleaner 1.

[Basic configuration]
FIG. 2 is a cross-sectional view of the vacuum cleaner 1 according to the embodiment. As shown in FIG. 2, the main body 2 includes a casing 2 a having a left and right half structure. A substantially C-shaped handle H is integrally formed outside the casing 2a, and a motor chamber 10 and a dust collecting portion 20 are formed inside the casing 2a.

  The motor chamber 10 has a built-in fan motor 11 that is an electric blower. The fan motor 11 includes a suction fan 11a and a motor 11b. The suction fan 11a is a centrifugal fan that blows out air sucked from the center toward the outer periphery. While the fan motor 11 is elastically supported by rubber packings (elastic bodies) 12 a and 12 b provided on the upper and lower sides of the fan motor 11, air is prevented from leaking from the motor chamber 10.

  The dust collection unit 20 is an internal space that temporarily collects the sucked dust. The tip of the extension pipe 3 is attached to the suction port 21, and one end of the paper pack holder 23 is in contact with the rubber packing 22 above the suction port 21. This abutting surface is formed obliquely in a side view and increases the degree of adhesion. The other end of the paper pack holder 23 is closed by a paper pack P (not shown). The paper pack P is a disposable dust bag formed using a nonwoven fabric or the like. A lid 24 is formed on the front side of the dust collecting unit 20. When the lid 24 is removed, the dust collecting unit 20 is exposed to the external space, and the paper pack P can be replaced.

  The handle H includes a grip portion H2 having substantially the same thickness. On the front side of the grip portion H2, an operation button H1 that a user operates with a fingertip is provided. If a convex part or a concave part is provided on the back side of the grip part H2 so that the user's finger is applied, the position of the user can be guided to a certain position, and the operation button H1 can also be pressed. It becomes easy.

[Optimize center of gravity balance]
Here, in the present embodiment, as shown in FIG. 2, the fan motor 11 is disposed near the rear of the handle H, and the duct component member 30 is provided between the fan motor 11 and the dust collecting portion 20. The dust collection unit 20, the duct component member 30, and the fan motor 11 are arranged linearly along the longitudinal direction of the main body 2, and the fan motor 11 and the dust collection unit 20 are communicated with each other by the duct component member 30.

  Since the stick-type vacuum cleaner 1 has a vertically long shape with the front part longer than the main body 2, if the heavy fan motor 11 is arranged behind the handle H, the balance of the center of gravity when the handle H is held is maintained. Can be optimized. In other words, since the entire center of gravity is closer to the rear, it feels lighter than the actual weight and is easy to handle.

  The duct component member 30 is a cylindrical member that constitutes the duct 31. One end 31 a of the duct 31 is connected to the opening 26 of the dust collection unit 20. The other end 31 b of the duct 31 is connected to the suction port 13 formed at the lower end of the cover 13 a that covers the fan motor 11. The shape of the duct component 30 will be described in detail later.

  The diameter of the duct 31 is adjusted to the diameter of the suction port 13 of the fan motor 11, and a relatively wide space 32 is secured between the duct 31 and the casing 2a. Various cables such as the power cable C can be routed in the space 32 (described later). The length of the duct 31 can be appropriately adjusted according to the balance of the center of gravity, the shape of the handle H, and the like.

  The handle H is provided outside the casing 2a. A front end H3 of the handle H is connected at a position in front of the fan motor 11, and a rear end H4 of the handle H is connected in a position behind the fan motor 11. If the vicinity of the front end H3 of the handle H is made thinner than the vicinity of the rear end H4, the center of gravity position is brought to the rear side. In order to adjust the weight balance when the user grips the grip portion H2, the grip portion H2 is inclined at an appropriate angle toward the main body 2 side.

  Specifically, the handle H includes a first extending part H11, a gripping part H20, and a second extending part H12. The first extending portion H11 is a portion whose base end is connected to the rear portion of the casing 2a and extends outward. The gripping part H20 is a part that is connected to the distal end of the first extending part H11, and is formed so as to gradually move away from the casing 2a while extending forward from the proximal end. The second extending portion H12 has a proximal end connected to the distal end of the gripping portion H20, is formed so as to gradually approach the casing 2a while extending forward from the proximal end, and a portion where the distal end is connected to the outer surface of the casing 2a It is.

[Operation]
When the user slides the operation button H1 of the handle H, the motor 11b is activated and the suction fan 11a rotates. When the suction fan 11a rotates, a negative pressure is generated inside the vacuum cleaner 1, air flows from the suction head 4 through the extension pipe 3 to the main body 2 side, and the paper pack P of the dust collecting unit 20 (see FIG. 9). As a result, dust in the air is removed. Fine dust that has not been removed by the paper pack P is removed by a sponge filter 25 provided behind the dust collecting unit 20. The cleaned air flows into the motor chamber 10 through the duct 31. The air that has flowed into the motor chamber 10 is discharged from an exhaust port (described later) formed in the motor chamber 10 to the external space.

  As described above, the vacuum cleaner 1 according to the embodiment includes the casing 2a, the suction port 21 provided in the casing 2a, the handle H provided outside the casing 2a, and the fan provided in the casing 2a. The motor 11, a cylindrical duct component 30 provided in the casing 2 a, and a dust collection unit 20 provided in the casing 2 a are provided. In addition, the dust collection unit 20, the duct component member 30, and the fan motor 11 are sequentially arranged in the casing 2a. The duct component member 30 has one end 31a connected to the opening 26 of the dust collection unit 20 and the other end. 31 b is connected to the suction port 13 of the fan motor 11, and the dust collecting unit 20 and the fan motor 11 are communicated with each other via a duct component 30. Thereby, since the freedom degree of design can be aimed at, it becomes possible to optimize centroid balance and to improve operativity. Further, since the distance between the fan motor 11 and the dust collecting unit 20 can be increased while improving airtightness, it is possible to improve the suction force.

  Further, the dust collecting unit 20, the duct constituent member 30, and the fan motor 11 are arranged along the front-rear direction when the side where the suction port 21 is located is the front, and at least a part of the handle H is front-rear. The front end H3 extends along the direction, and is connected to the outer surface of the casing 2a at a position in front of the fan motor 11, and the rear end H4 is connected to the outer surface of the casing 2a in a position behind the fan motor 11. Thereby, although the handle H is provided, interference between the handle H and the dust collecting unit 20 can be avoided, and thus airtightness can be ensured.

  Further, the front end H3 of the handle H is formed narrower than the rear end H4. Thereby, there exists an effect which makes a gravity center position back.

  The fan motor 11 is disposed near the rear of the handle H. As a result, the center of gravity of the whole is closer to the rear, so that it feels lighter than the actual weight and is easy to handle.

  The handle H has a proximal end connected to the rear portion of the casing 2a, a first extending portion H11 extending outward, and a proximal end connected to the distal end of the first extending portion H11. A gripping part H20 formed to extend further forward and gradually separated from the casing 2a, and a base end is connected to the distal end of the gripping part H20, and formed to gradually approach the casing 2a while extending forward from the base end. And a second extending portion H12 whose tip is connected to the outer surface of the casing 2a. Thereby, not only can the center of gravity position be adjusted, but the handle H can be easily held to improve operability.

[Cable mounting structure]
Drawing 3 is an explanatory view of the cable attachment structure of vacuum cleaner 1 concerning an embodiment. Here, the state which removed the one side of the casing 2a of the right-and-left half structure is shown. Although it is desirable to make the width of the motor chamber 10 as thin as possible, if the motor chamber 10 is made narrow, the space for routing the cable inside the motor chamber 10 is limited.

  Therefore, in the present embodiment, as shown in FIG. 3, the cable is routed around the space 32 around the inside of the handle H and the duct 31. Specifically, the power supply cable C that receives external power supply is drawn into the space 32 between the casing 2a and the duct component 30 from the outside of the casing 2a. Further, a wiring C1 electrically connected to the power cable C passes through the inside of the handle H from the front end H3 to the rear end H4 of the handle H and is connected to the fan motor 11.

  Note that the type and number of cables routed around the handle H and the space 32 around the duct 31 and the routing direction are not limited. For example, the wiring of a thermal fuse (not shown) provided in the fan motor 11 may be connected to the terminal of the operation button H1 through the inside of the handle H. A plurality of wires can be routed from the front to the rear or from the rear to the front.

  As described above, the vacuum cleaner 1 according to the embodiment further includes the power cable C that receives external power supply, and the power cable C is provided between the casing 2a and the duct component 30 from the outside of the casing 2a. A wiring C1 drawn into the space 32 and electrically connected to the power cable C passes through the inside of the handle H from the front end H3 to the rear end H4 of the handle H and is connected to the fan motor 11. As a result, since the wiring C1 can be routed from the front to the rear of the fan motor 11 through the inside of the handle H, the wiring C1 does not have to be arranged on the outer peripheral side of the fan motor 11, and the size reduction can be achieved. It becomes possible. Further, since the power cable C can be pulled out obliquely toward the user side, operability can be improved.

[Independent structure]
Drawing 4 is an explanatory view of the self-supporting structure of vacuum cleaner 1 concerning an embodiment. As shown in FIG. 4, the casing 2 a has a flat surface F that is substantially orthogonal to the rotating shaft 11 </ b> C of the fan motor 11 in the vicinity of the rear portion of the handle H. Further, the rear end H4 of the handle H may have a surface continuous with the flat surface F. If it does in this way, the vacuum cleaner 1 can be made to stand on the floor 100 upside down. Since the flat surface F is substantially orthogonal to the rotating shaft 11C of the fan motor 11 which is a heavy object, the flat surface F can be stably made to stand by itself. Moreover, since the heavy fan motor 11 is disposed closer to the rear, it is possible to make it more stable and independent. Furthermore, since the power cable C is pulled out from the side of the casing 2a, the power cable C does not get in the way in a self-supporting state.

  As described above, the casing 2 a included in the vacuum cleaner 1 according to the embodiment has the flat surface F in the vicinity of the rear portion of the handle H that is substantially orthogonal to the rotation shaft 11 </ b> C of the fan motor 11. Thereby, since the vacuum cleaner 1 can be turned upside down so as to be independent on the floor 100, it is possible to improve the efficiency of the cleaning work and to reduce the space during storage.

[Cable storage structure]
Drawing 5 is an explanatory view of the cable storage structure of vacuum cleaner 1 concerning an embodiment. In FIG. 5A, the power cable C is omitted for easy understanding.

  As shown in FIG. 5A, a pair of cable winding hooks 41 and 42 are provided on the side of the casing 2a. The rear cable winding hook 41 is a substantially L-shaped rotatable hook. The front cable winding hook 42 is a substantially L-shaped fixing hook. Further, a C-shaped cable end holding hook 43 is provided between the pair of cable winding hooks 41 and 42.

  As shown in FIG. 5B, at the time of storage, the power cable C drawn out from the side of the casing 2a is wound between a pair of cable winding hooks 41 and 42. Since the base end portion of the power cable C is inclined toward the cable winding hook 41, the power cable C can be wound without difficulty. Further, the casing 2a above the cable winding hook 41 is formed with an inclined portion 2b inclined inward, and the casing 2a around the cable winding hook 42 is formed with a recess 2c. The power cable C can be easily wound. Since the power plug C2 is formed at the free end of the power cable C, the vicinity of the power plug C2 is hooked on the cable end holding hook 43. Since the cable end holding hook 43 is provided in front of the pull-out position C3 of the power cable C, the power cable C at the pull-out position C3 is arranged so as not to get in the way. If the cable winding hook 41 is rotated in this state, the power cables C can be released in a bundle.

  As described above, the vacuum cleaner 1 according to the embodiment includes a pair of cable winding hooks 41 and 42 and a cable for holding a cable end between the pair of cable winding hooks 41 and 42. An end holding hook 43 is provided. As a result, even when the cleaner 1 is stored in a self-supporting manner, the vicinity of the power plug C2 can be held by the cable end holding hook 43, so that the appearance during storage can be improved.

[Wall hanging structure]
FIG. 6 is an explanatory diagram of a wall standing holding structure of the vacuum cleaner 1 according to the embodiment. As shown in FIG. 6, a permanent magnet 41 a is provided inside the cable winding hook 41 and is attracted to the metal plate 201 on the wall 200 side. The metal plate 201 is a metal wall-mounting part and may be provided as an accessory of the cleaner 1. If the metal plate 201 is fixed to the wall 200 with double-sided tape, screws, or the like, the main body 2 can be stood along the wall 200 with the suction head 4 of the cleaner 1 placed on the floor.

  As described above, in the vacuum cleaner 1 according to the embodiment, the permanent magnet 41a is provided inside the cable winding hook 41 and is attracted to the metal plate 201 on the wall 200 side. As a result, the cable winding hook 41 and the wall holding / adsorbing portion can be used together, so that the number of parts can be reduced and the cost can be reduced.

[Paper pack mounting structure]
FIG. 7 is a diagram illustrating a state in which the paper pack P is attached to the paper pack holder 23 of the vacuum cleaner 1 according to the embodiment. As shown in FIG. 7, the paper pack holder 23 includes a cylindrical portion 23b protruding from the plate-like portion 23a. A through hole 23c is integrally formed at the center of the plate-like portion 23a and the cylindrical portion 23b. The through-hole 23 c serves as a flow path for circulating the air that has passed through the internal space of the extension pipe 3 to the dust collection unit 20. The paper pack P is attached so as to cover the tube portion 23b from the air outflow side, and the paper pack P is sandwiched by the paper pack mounting clip 23d provided at the base of the tube portion 23b. In order to easily sandwich the paper pack P, the tip of the paper pack mounting clip 23d is bent outward. When the paper pack P is sandwiched between the paper pack mounting clips 23d, the paper pack holder 23 and the paper pack holder 23 are set in the dust collecting unit 20. Dust in the air that has flowed into the paper pack P through the paper pack holder 23 cannot flow outside the paper pack P, but is collected inside the paper pack P.

  A check valve 23e that can be opened only in the air suction direction may be provided at the tip of the paper pack holder 23. For example, a through hole 23f is formed in a rubber check valve 23e, and the screw 23h is stopped in the screw hole 23i on the paper pack holder 23 side through the through hole 23f and a washer 23g. When no negative pressure is generated inside the vacuum cleaner 1, the check valve 23 e comes into contact with the tip of the paper pack holder 23. As a result, the dust collected inside the paper pack P does not return to the paper pack holder 23 side.

  FIG. 8 is an explanatory diagram of the paper pack mounting structure of the vacuum cleaner 1 according to the embodiment. Here, the dust collection unit 20 is shown in a spread state. The paper pack holder 23 is removed from the left and right half-structure casing 2a, and the lid 24 of the dust collecting unit 20 is also removed. In the drawing, the uppermost casing 2a and the lowermost lid 24 are drawn so that the internal structure can be easily seen and rotated in the direction. When the hook 28 on the lid 24 side is hooked on the groove portion 27 on the casing 2a side, the lid 24 of the dust collecting unit 20 can be closed.

  Here, in the present embodiment, as shown in FIG. 8, a structure is employed that prevents the problem that the paper pack P is detached from the paper pack holder 23 due to the air pressure of the air flowing in through the paper pack holder 23. Yes. Specifically, clip restraining ribs 29 a, 29 b and 29 c that restrain the vicinity of the tip of the paper pack mounting clip 23 d are formed inside the dust collecting portion 20. The clip restraining ribs 29a, 29b, and 29c are formed in a substantially fan shape when viewed from the longitudinal direction of the main body 2. When the lid 24 of the dust collecting part 20 is closed, the inner edges E1, E2, E3 of the clip restraining ribs 29a, 29b, 29c restrain the vicinity of the tip of the paper pack mounting clip 23d.

  As described above, in the vacuum cleaner 1 according to the embodiment, the clip restraining ribs 29a, 29b, and 29c that restrain the vicinity of the tip of the paper pack mounting clip 23d are formed inside the dust collecting portion 20. As a result, the holding force of the paper pack mounting clip 23d can be increased, so that it is possible to prevent the paper pack from coming off due to strong suction.

[Inner wall shape of dust collector]
Drawing 9 is an explanatory view of the inner wall shape of dust collection part 20 with which vacuum cleaner 1 concerning an embodiment is provided. Although this vacuum cleaner 1 is a slim stick type, it is a wired AC power supply type, and thus realizes a strong suction force. Therefore, when air is sucked in the state where dust is collected in the paper pack P, the paper pack P may swell until it comes into close contact with the inner wall of the casing 2a, and the suction force may be reduced.

  Therefore, in the present embodiment, a plurality of protrusions T are formed on the inner wall of the dust collecting portion 20 as shown in FIG. Here, only one side of the left and right half-structured casing 2a is illustrated, but a similar protrusion T is formed on the other side. The number and shape of the protrusions T are not particularly limited. For example, as shown in the enlarged view of FIG. 9B, nine protrusions T1 to T9 may be formed in the vicinity of the duct component member 30 along the air flow path. In this way, the air flow path to the fan motor 11 can be effectively secured.

  As described above, in the vacuum cleaner 1 according to the embodiment, the plurality of protrusions T are formed on the inner wall of the dust collection unit 20. As a result, a gap can be secured between the inner wall of the dust collecting unit 20 and the paper pack P. As a result, it is possible to suppress a decrease in suction force, and it is possible to suppress an increase in temperature of the fan motor 11.

[Motor support structure]
FIG. 10 is an explanatory diagram of the motor support structure of the vacuum cleaner 1 according to the embodiment. FIG. 10A shows a state in which one side of the casing 2a having a left / right halved structure is removed, and FIG. 10B shows a state in which members inside the casing 2a are further removed. FIG.10 (c) is a side view of the duct structural member 30 shown by FIG. 10 (a) (b).

  As shown in FIG. 10, the duct component member 30 includes flange portions 34b and 34c at both ends of the tube portion 34a. The upper collar portion 34b includes a concave portion 34f that opens upward, and an opening 34g that communicates with the duct 31 is formed at the bottom of the concave portion 34f. Also, fins 34x that abut on the sponge filter 25 are radially arranged on the lower surface of the lower collar portion 34c. Further, a disc annular positioning collar 34d projecting outward is formed below the upper collar portion 34b, and a similar positioning collar 34e is also formed above the lower collar portion 34d. Yes.

  As described above, air is prevented from leaking from the motor chamber 10 while elastically supporting the fan motor 11 with the rubber packings 12 a and 12 b provided above and below the fan motor 11. Specifically, a rotation restricting rib W1 for restricting the protrusion K1 of the upper rubber packing 12a from the left-right direction is formed in the casing 2a. The protrusion K1 of the rubber packing 12a is fitted into the recess K2 on the upper surface of the fan motor 11, and the lower rubber packing 12b is fitted into the lower end of the fan motor 11 and fitted into the recess 34f of the duct component member 30. The lower rubber packing 12b is a ring-shaped rubber packing having an opening 12c. The inner diameter of the opening 12c is formed in a tapered shape that decreases downward in accordance with the outer peripheral size of the cover 13a that covers the fan motor 11 (see FIG. 2). Thereby, the rubber packing 12b and the fan motor 11 can be brought into close contact with each other without any gap, and the fan motor 11 can be centered with respect to the duct component 30. The inner wall W2 of the casing 2a is inserted between the flange portion 34b of the duct component 30 and the positioning flange 34d, and the inner wall W3 of the casing 2a is interposed between the flange portion 34c of the duct component 30 and the positioning flange 34e. enter. Further, a sponge filter 25 is inserted between the inner walls W3 and W4 of the casing 2a.

  As described above, in the vacuum cleaner 1 according to the embodiment, the fan motor 11 is sandwiched between the rubber packings 12 a and 12 b provided above and below the fan motor 11. Thereby, the fan motor 11 can be elastically supported with respect to the front-rear direction and the radial direction of the fan motor 11.

  Moreover, in the vacuum cleaner 1 which concerns on embodiment, the rubber packing 12a above the fan motor 11 is being fixed in the casing 2a. Thereby, the fan motor 11 can be elastically supported also in the rotation direction of the fan motor 11.

[Exhaust direction restriction structure]
Drawing 11 is an explanatory view of the exhaust direction regulation structure of vacuum cleaner 1 concerning an embodiment, (a) is a perspective view and (b) is a sectional view. As shown in FIG. 11, the motor chamber 10 includes a slit-shaped exhaust port 51 that discharges air to the external space. It is uncomfortable if the exhaust from the exhaust port 51 is ejected toward the user holding the handle H. Therefore, exhaust direction regulating ribs 52 extending obliquely rearward are formed inside each exhaust port 51. If it does in this way, the exhaust E from each exhaust port 51 will be ejected toward the front. Of course, the exhaust direction can be appropriately adjusted by the shape of the exhaust direction regulating rib 52.

  As described above, in the vacuum cleaner 1 according to the embodiment, the exhaust direction restriction ribs 52 extending obliquely rearward are formed inside the exhaust ports 51. Thereby, since the exhaust E from each exhaust port 51 is ejected forward, it becomes possible to improve the user's comfort.

[Suction head suction port shape]
Drawing 12 is an explanatory view of the suction mouth shape of suction head 4 with which vacuum cleaner 1 concerning an embodiment is provided. The suction head 4 is a cyclone head that raises a suction force by generating a swirling airflow. That is, a spiral airflow having the longitudinal direction of the suction head 4 as a rotation axis is generated, and dust scattered on the floor is scraped out by the generated airflow. A suction port 61 for sucking dust from the surface to be cleaned is provided on the lower surface of the suction head 4. A recess 63a is provided at the front end 63 of the suction port 61 in order to make it easier to suck forward dust. Further, in order to make it easy to suck in dust on the wall, suction ports 61 are extended to the end portions 62 on both sides of the suction head 4.

  As described above, in the vacuum cleaner 1 according to the embodiment, the recess 63 a is provided at the front end 63 of the suction port 61 of the suction head 4. As a result, even if the clip or the like has a certain thickness, it can be sucked through the gap formed by the recess 63a, so that the suction performance can be improved.

  Although not particularly mentioned in the above description, it is needless to say that various protection functions provided in the general vacuum cleaner 1 may be provided. For example, a bimetal is provided in the vicinity of the fan motor 11, and the operation is completely stopped when abnormal heat is generated.
