Description

  The present invention relates to a suction head of a vacuum cleaner and a vacuum cleaner.

  Patent Document 1 proposes a floor nozzle of an electric vacuum cleaner in which a suction port and a dust collecting unit located at a position separated from the suction port are provided at the bottom of the floor nozzle body. The dust collecting part is composed of a rotor having a raised brush on the peripheral surface and a scraping plate for scraping dust such as lint captured by the raised brush, and the suction port and the dust collecting part are electrically cleaned. It is communicated with a joint for connecting to the machine body side.

  A dust collecting portion is disposed below the partition wall for forming a flow path that connects the suction port and the joint, and an opening is formed in the partition wall so that the dust collecting portion and the joint communicate with each other.

  In addition, Patent Document 2 aims to provide a compact manual cleaning tool that is easy to collect and discharge dust, can be cleaned even in a narrow space, and is quiet and comfortable to use. A manual body equipped with a lid that can collect dust in the dust collection chamber by moving the dust collector provided with a dust removal brush back and forth against the surface to be cleaned and reciprocating back and forth. A cleaning tool has been proposed.

JP-A-63-255026 JP 2009-207646 A

  In the floor nozzle disclosed in Patent Document 1, the brush protrudes from the bottom when dust is sucked from the suction port and the opening of the partition wall is closed, and the dust is collected from the bottom when the dust collecting part is entangled. Is provided with a lever for switching so that the opening of the partition wall is opened while retreating.

  For this reason, when entwining yarn waste using the dust collecting part, it is impossible to secure the dust absorption force from the suction port, and conversely, when dust is sucked from the suction port, the dust collecting part is used. There was a problem that yarn wastes could not be entangled.

  For example, when removing lint and hair entangled in a carpet, etc., as well as pet hair, make both lint collection using a dust collecting part and dust absorption from the suction port function. However, it is difficult to function both at the same time, and it is necessary to perform complicated cleaning work by operating the lever after removing dust in one of the dust collecting part or the suction port and removing dust again on the other side. .

  Therefore, it is conceivable that by always opening the opening of the partition wall, both the entanglement of lint using the dust collecting portion and the dust suction from the suction port are allowed to function. When the opening area is small, the yarn waste or the like is not collected from the opening of the partition wall, and dust accumulates. When the opening area is large, there is a problem that the dust absorption force from the suction port decreases. In addition, when the amount of entanglement of yarn waste using the dust collection part is very large, even if the opening area is increased, the thread collection or the like accumulates in the dust collection part. There was also a problem of end.

  Although the manual cleaning tool described in Patent Document 2 can entangle yarn waste and the like, dust cannot be sucked, so it is necessary to finally remove the dust with an electric vacuum cleaner, which is troublesome. No difference from the floor nozzle disclosed in FIG.

  In view of the above-described conventional problems, the object of the present invention is to allow both the entanglement of yarn waste and the dust suction from the suction port to function properly and easily remove even when the yarn waste is clogged. It is in the point which provides the suction head and vacuum cleaner of a vacuum cleaner.

  In order to achieve the above object, the first characteristic configuration of the suction head of the vacuum cleaner according to the present invention is formed to face the cleaning surface as described in claim 1 of the claims. A first suction port, a joint to which a suction hose or a suction pipe is connected, a first curved portion on the outer peripheral side, and a second curved portion on the inner peripheral side, are arranged above the first suction port. The outer peripheral surface is provided with a collection portion formed by a suction flow path that is curved so as to be convex and communicated with the joint portion, an inner surface side of the second curved portion, and a cleaning surface, and is configured by a raised brush. A semi-cylindrical rotor, and a storage unit provided with a removal unit configured by a brush raised to remove dust collected by the collection unit in sliding contact with the collection unit, A part of the second bending portion has a second suction port communicating with the suction flow path, and the first bending portion Part forming an opening, in that it comprises an openable lid said opening.

  Even if dust such as lint collected in the collection part becomes a large amount and becomes a lump and is not sucked into the flow path from the storage part to the joint part via the second suction port, the lid is removed. From the opening formed in the exposed first curved portion, the dust collected in the storage portion can be taken out by using a jig such as tweezers or by picking it with a finger. Since the dust collecting function such as waste can be properly restored, the desired function can be maintained over a long period of time.

  According to the second characteristic configuration, as described in the second aspect, in addition to the first characteristic configuration described above, the lid body is associated with an upper cover body that covers the first curved portion via a locking portion. The point is that it is removably locked.

  Even without using a special dedicated jig, the opening can be easily opened by simply releasing the locking state between the lid and the upper cover.

  As described in the third aspect, the third characteristic configuration is that, in addition to the second characteristic configuration described above, the lid body is connected to the upper cover body via a hinge.

  If the lid is detached from the upper cover body with the opening opened, and the time elapses in this state, the lid body may be lost. However, if the lid is connected to the upper cover body via the hinge, the lid body is connected to the upper cover body even if the opening is opened, which may cause a disadvantageous situation such as losing the lid body. And never forget to put on the lid.

  In the fourth feature configuration, as described in claim 4, in addition to the second or third feature configuration described above, the opening is kept secret between the first bending portion and the lid. The sealing member for closing is provided.

  Since sealing is performed with the seal member, outside air does not flow into the opening from the gap between the lid and the first bending portion, and negative pressure acting on the first suction port and the second suction port from the joint portion is prevented. There is no possibility that the dust absorption force is lowered due to the decrease.

  In the fifth feature configuration, as described in claim 5, in addition to the fourth feature configuration described above, the lid body is provided substantially above the second suction port. .

  Since the second suction port can be directly accessed from the opening formed in the first curved portion without hindrance, the dust collected in the storage portion can be easily removed.

  As described in the sixth aspect of the present invention, the vacuum cleaner according to the present invention includes the suction head of the vacuum cleaner having any one of the first to fifth characteristics described above.

  Both entanglement of yarn waste and dust suction from the suction port can be made to function properly and simultaneously, and prompt cleaning work is possible. Even if dust such as lint grows in a lump and becomes clogged, it can be easily removed, and the intended function can be restored without having to be repaired outside.

  As described above, according to the present invention, the vacuum cleaner can appropriately remove both the entanglement of the yarn waste and the dust suction from the suction port, and can be easily removed even when the yarn waste or the like is clogged. Suction head and vacuum cleaner can be provided.

  As shown in FIG. 3B, the lower cover body 10 includes a wide-width portion 10A having a rectangular shape in plan view located on the distal end FE side of the suction head 6 and a narrow-width portion 10B having a rectangular shape in plan view located on the base end RA side. The universal joint 32 of the joint part 30 is fixed to the narrow part 10B.

  A concave groove 11 extending to the left and right is formed slightly to the front end side of the wide portion 10A in the front-rear direction center, and a rectangular opening serving as the first suction port 12 is formed in the left and right width direction central portion of the concave groove 11. Has been.

  Further, the rollers 15 are respectively attached to the left and right width direction end portions on the distal end FE side of the wide portion 10A, and the rollers 16 are respectively attached to the base end RA side of the narrow portion 10B.

  As shown in FIG. 4 and FIG. 4B, the second bending portion 13 having an arcuate cross section is formed on the proximal end RA side adjacent to the concave groove 11 so as to bulge upward. A long hole-shaped opening serving as the second suction port 14 is formed in the left and right center portion of the top portion.

  2 (b) and FIGS. 4 (a) and 4 (b), the upper cover body 20 is covered on the upper portion of the second bending portion 13, and is formed at the left and right width direction center portions of the upper cover body 20. A belt-like curved flow path FP partitioned by the first curved portion 21 and the second curved portion 13 is formed.

  The second joint pipe 33 is hermetically fixed via a seal member between the lower cover body 10 and the upper cover body 20 so that the rear end side of the belt-shaped curved flow path FP communicates with the second joint pipe 33, The lower cover body 10 and the upper cover body 20 are fixed with screws so that the distal end side of the curved flow path FP communicates with the first suction port 12. That is, the curved flow path FP becomes the suction flow path 18 that connects the first suction port 12 and the joint portion 30.

  As shown in FIGS. 2 (b) and 3 (b), an accommodating portion 40 is formed in the lower space of the second bending portion 13, and a collecting portion 41 composed of a raised brush is arranged on the outer periphery of the accommodating portion 40. A semi-cylindrical rotor 42 provided on the surface is rotatably accommodated, and a removing unit 43 configured by a brushed brush that slides on the collecting unit 41 and removes dust collected by the collecting unit 41 is provided. Contained.

  A support shaft 42A protrudes from the left and right sides of the rotor 42, and the support shaft 42A is pivotally supported by a support portion 13A formed on the left and right side walls of the second bending portion 13.

  As shown in FIG. 5 (b), the curved top portion of the semi-cylindrical rotor 42 is provided with a linear protrusion 44 made of an elastic body along the rotational axis direction of the rotor 42. When reciprocating toward the front end FE side and the base end RA side in contact with the cleaning surface, the semi-cylindrical rotor 42 rotates clockwise or counterclockwise due to friction between the cleaning surface and the protrusion 44. Is configured to do.

  For example, when the suction head 6 is moved to the distal end FE side, the rotor 42 rotates counterclockwise, and when the suction head 6 is moved to the proximal end RA side, the rotor 42 rotates clockwise.

  The raising brush which comprises the collection part 41F arrange | positioned at the front-end | tip FE side rather than the processus | protrusion 44 is installed so that it may incline to the front-end | tip FE side along the outer peripheral surface of the rotor 42, and it is on the rear end RA side rather than the processus | protrusion 44. The raising brush which comprises the collection part 41R arrange | positioned is installed so that it may incline toward the rear-end RA along the outer peripheral surface of the rotor 42. As shown in FIG.

  Therefore, when the suction head 6 is moved to the front end FE side, lint, hair, and the like are entangled and removed from the cleaning portion 41F from the cleaning surface, and when the suction head 6 is moved to the rear end RA side, the yarn is removed from the cleaning surface. Debris, hair, and the like are entangled with the collecting portion 41R and removed.

  Inside the lower end portion of the second bending portion 13, the removal portions 43F and 43R are arranged so as to be in sliding contact with the collection portions 41F and 41R, respectively. The raised brush constituting the removing portion 43F is provided so as to be inclined toward the front end FE, and the raised brush constituting the removing portion 43R is provided so as to be inclined toward the rear end RA.

  When the suction head 6 is moved forward, dust on the cleaning surface is captured by the collecting portion 41F on the front end FE side, and when the suction head 6 is moved backward, dust in a state where the dust is captured by the collecting portion 41F slides on the removing portion 43F. Exit. When the suction head 6 is moved forward again, the dust trapped in the trapping portion 41F when the rotor 42 rotates counterclockwise is removed by the removing portion 43F and opened to the storage portion 40 which is the internal space of the rotor 42. . At this time, dust is collected in the suction flow path 18 through the second suction port 14 from the inner space of the rotor 42 that is negatively pressured by the electric blower housed in the main body case.

  Similarly, when the suction head 6 is moved backward, dust on the cleaning surface is captured by the collecting portion 41R on the rear end RA side, and when the suction head 6 is moved forward, dust in a state where the dust is captured by the collecting portion 41R is removed. Slide through the portion 43R. When the suction head 6 is moved back again, the dust trapped in the trapping portion 41R when the rotor 42 rotates in the clockwise direction is removed by the removing portion 43R and opened to the accommodating portion 40. At this time, dust is collected in the suction flow path 18 through the second suction port 14 from the inner space of the rotor 42 that is negatively pressured by the electric blower housed in the main body case.

  The distance between the cleaning surface and the bottom surface of the lower cover body 10 is defined by the rollers 15 and 16, and the height of the rotor 42 with respect to the second curved portion 13 is such that the cleaning surface and the collecting portion 41 are in contact with each other. Is set.

  Further, at this time, the opening area of the second suction port 14 is adjusted so that the negative pressure generated in the first suction port 12 and the negative pressure generated in the accommodating portion 40 are balanced. Therefore, fine dust on the cleaning surface is sucked into the suction channel 18 from the first suction port 12, and thread-like dust on the cleaning surface is sucked into the suction channel 18 from the second suction port 14. Become.

  However, when a large amount of dust such as lint or hair is present on the cleaning surface, the amount of dust captured by the collection unit 41 increases, and thus is removed by the removal unit 43 and opened to the storage unit 40. In this state, a large lump is formed, and it is difficult for dust to be sucked into the suction flow path 18 from the second suction port 14. If lumps such as lint are accumulated in the accommodating portion 40, the function of capturing the lint-like dust is lost. There is a risk of being.

  Therefore, as shown in FIGS. 2 to 5, the suction head 6 according to the present invention has an opening 22 formed in a part of the first bending portion 21, and further includes a lid 23 that can open and close the opening 22. ing.

  Even when dust such as lint collected in the collection part 41 is abundant and agglomerated and is not sucked into the suction flow path 18 from the storage part 40 to the joint part 30 via the second suction port 14, From the opening 22 formed in the first curved part 21 exposed by removing the lid 23, the dust collected in the storage part 40 is taken out by using a jig such as tweezers or picking it up with a finger. Will be able to.

  Specifically, the lid body 23 is configured by a substantially rectangular plate-like body that is curved so as to follow the curved surface of the first curved portion 21, and the hinge 25 that can be connected to the first curved portion 21 on the rear end RA side. And a locking portion 26 that engages with the first bending portion 21 on the distal end FE side.

  A locking portion 26 is configured by a locking protrusion that engages with an engaging recess formed in the first bending portion 21, and the first bending is performed in the engagement state with the first bending portion 21 in the vicinity of the locking portion 26. A recess 27 is formed between the portion 21 and a slight gap.

  By inserting a coin or a flathead screwdriver into the recess 27 and twisting it, the engagement state is canceled and the opening 22 is opened. Since the opening 22 is formed above the second suction port 14, dust collected in the storage unit 40 can be removed via the opening 22 and the second suction port 14, and the collection unit By properly recovering the dust collecting function of yarn waste and the like by 41, the intended function can be maintained over a long period of time.

  Since the lid body 23 is connected to the upper cover body 20 via the hinge 25, an inconvenient situation that the lid body 23 is lost does not occur, and the lid body 23 is not forgotten to be attached.

  As shown in FIG. 4A, a seal member 24 is provided between the first bending portion 21 and the lid body 23 to secretly close the opening 22, and the seal member 24 is attached with the lid body 23 attached. Since it is sealed via a foamed rubber sheet 28 affixed to the back surface of the lid 23 so as to cover the periphery, outside air may flow into the opening 22 from the gap between the lid 23 and the first bending portion 21. There is no possibility that the negative pressure acting on the first suction port 12 and the second suction port 14 from the joint portion 30 is reduced and the dust suction force is reduced.

  Since the lid body 23 is provided substantially above the second suction port 14, the second suction port 14 can be directly accessed from the opening 22 formed in the first bending portion 21 without any trouble, and the storage portion The dust collected in 40 can be easily removed.

  That is, the suction head 6 of the vacuum cleaner according to the present invention includes a first suction port 12 formed so as to face the cleaning surface, a joint portion 30 to which the suction hose 3 or the suction pipe 4 is connected, and an outer peripheral side. A suction flow path 18 that is formed of a first curved portion 21 and a second curved portion 13 on the inner peripheral side, is curved so as to protrude upward from the first suction port 12, and communicates with the joint portion 30. The semi-cylindrical rotor 42, which is formed by the inner surface side of the second bending portion 13 and the cleaning surface and has a collection portion 41 formed of a raised brush on the outer peripheral surface, is slidably brought into contact with the collection portion 41. And a storage portion 40 provided with a removal portion 41 constituted by a raised brush that removes dust collected by the collection portion 41, and communicates with the suction flow path 18 in a part of the second bending portion 13. The second suction port 14 is formed, an opening 22 is formed in a part of the first bending portion 21, and the opening 2 includes an openable lid 23 is constructed.

  The second suction port 14 only needs to be formed in the second bending portion 13, and does not necessarily have to be formed at the top of the second bending portion 13. However, the opening 22 formed in the first curved portion 21 needs to be formed at a position where lumps such as yarn waste accumulated in the storage portion 40 can be removed via the second suction port 14. There is.
