Description

  The present invention relates to a vacuum cleaner, and more particularly to a vacuum cleaner capable of locking a joint pipe to a vacuum cleaner body.

  When cleaning with a conventional vacuum cleaner, it can be smoothly cleaned in a place where there is no obstacle (such as a corridor), but there are obstacles such as a table in a room or a living room to some extent. For this reason, when cleaning with an electric vacuum cleaner, the obstacles obstruct the cleaning, and it is necessary to place the hand control pipe and the expansion joint pipe on the floor or wall many times. At this time, when placed on the floor, it is necessary to perform bending and stretching operations such as standing and sitting, which may be a burden on the lower back and knees and may cause back pain. Also, when standing against a wall or the like, there is a possibility that the hand control tube may fall down with some time and scratch the floor or the like.

  As a conventional technique for solving such a problem, an engaging portion is arranged on the side surface of the hose joint portion, a locking portion is provided on the side surface of the extension pipe, and the locking portion is inserted into the locking portion of the hose joint portion to There is a thing to make (refer patent document 1).

Japanese Patent No. 3371513

  However, in the hose joint portion and the expansion joint pipe that are configured in the above-described prior art, the support portion is in a low position (specifically, almost the center point of the connection pipe). As a result, the stability is poor, the force is applied to the support portion, and the locking portion may be broken. In addition, when force is applied when attaching to the locking part of the expansion joint pipe, there is no receiving part with the floor surface under the hose joint part, so the main body tilts forward etc. There is a fear.

  The present invention solves such problems, and provides a vacuum cleaner that can improve the convenience of the user and can stably lock a hose, a hand control pipe, a joint pipe, and the like. .

  A handheld handle between the vacuum cleaner body and the hose is a locking part that can lock the joint pipe, and the handheld handle can be locked even when the electric blower is in operation and when the electric blower is stopped. A locking portion is provided in the portion, from which the joint pipe can be detachably locked from above. Preferably, the locking portion is provided at a position higher than the hose joint portion. Preferably, a portion for further improving the stability is provided at the lower portion of the hand-held handle when the joint pipe is integrated with the longitudinal side surface.

  According to the present invention, since the user can fix the joint pipe without bending and stretching by locking the joint pipe to the main body of the vacuum cleaner even in the usage state of the vacuum cleaner, the convenience of the user is improved. In addition to being able to improve, it is possible to stably lock the object to be locked by raising the locking position of the joint pipe to the cleaner body side from the floor surface.

  For example, when cleaning a room or living room, even if an obstacle such as a table exists, the obstacle can be moved while being cleaned. For this reason, the suction port and the expansion joint pipe are not placed on the floor, and the back pain and the like caused by the burden on the waist and knees due to the bending and stretching operations of standing and sitting are eliminated. Also, when standing on a wall or the like, there is no possibility that the hand control tube will fall down with some time and the floor or the like will be scratched. Furthermore, the locking portion is provided at a position higher than the hose joint portion, so that the stability is improved, and the hose, the expansion joint pipe and the like are less likely to fall during locking.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 is an external perspective view of a vacuum cleaner used in the present invention. A vacuum cleaner body 1, a hose 2, a hand control pipe 3, an expansion joint pipe 4, and a suction port 5 are provided. The vacuum cleaner body 1 and the hand control pipe 3 are connected by a hose 2, and the telescopic joint pipe 4 is connected to the hand control pipe 3. The suction port 5 is connected via the connector. A hand-held handle 21 exists between the cleaner body 1 and the hose 2 and is attached so that the hose 2 penetrates. A hose edge 5 is provided at the foremost part of the vacuum cleaner main body 1, and a command is issued from the hose 2 to the hose edge 5 by operation of the hand operation tube 3 to control the operation of the electric blower (described later). The hose 2 is connected to a hose edge 5 via a hose joint 2a. The hand-held handle 21 may be attached to the hose joint 2a. The expansion joint pipe 4 may be a joint pipe having no elasticity.

  The vacuum cleaner main body 1 incorporates an electric blower (described later) in the rear of the main body case, and sucks dust in the intake flow by sucking in from the suction port 5 by the suction force of the electric blower. A structure in which air is sucked into the vacuum cleaner main body 1 through the expansion joint pipe 4, the hand control pipe 3, and the hose 2 and is collected outside the cyclone separation dust case (described later) and then exhausted outside the machine. become.

  In addition, the vacuum cleaner main body 1 defines the side where the hose edge 5 is provided as the front. Moreover, it is preferable that the vacuum cleaner main body 1 is placed horizontally so that the hose edge 5 faces in the horizontal direction in the usage form, and is placed vertically so that the hose edge 5 faces in the vertical direction (upward direction) in the storage form.

  FIG. 2 is an internal structure diagram of the main body of the vacuum cleaner used in the present invention as seen from the top surface. When cleaning (use form), the power cord plug 9 disposed at the cord port 12 is put into a household outlet, and the electric blower 15 is driven by the electric power from the outlet. Then, the dust is sucked into the main body through the dust case 14. At this time, the power cord plug 9 is linked to the power cord 8, and the power cord 8 having a length of about 5 m is housed in the cleaner body 1 so that the cleaner body 1 can easily move during cleaning. Yes. When performing actual cleaning, it is normal that the power cord 9 housed in the cleaner body 1 is discharged from the cleaner body 1 to the outside, and the cleaner body 1 freely moves and cleans. is there. After cleaning, the power cord plug 9 is unplugged from the household outlet and the power cord take-up button 10 is pressed, and the power cord 8 is automatically housed in the cleaner body 1.

  FIG. 3 shows a vacuum cleaner when an obstacle is moved during use of the present invention. Originally, when cleaning is performed, the operator holds the hand control tube 3 and presses against a floor or carpet containing dust from the suction port 5 while standing, and removes dirt by a reciprocating motion. However, if there is an obstacle on the floor or the like, the hand control tube 3 or the expansion joint tube 4 must be placed on the floor or the like as shown in FIG. After moving the obstacle, cleaning is performed again by reciprocating the suction port 5 in the same state.

  However, at this time, every time there is an obstacle, the operation of placing the hand control tube 3 and the expansion joint tube 4 on the floor or the like places a burden on the user's lower back and knees and causes back pain and the like due to the bending and stretching movements. there is a possibility. In addition, placing the hand control pipe 3 and the expansion joint pipe 4 on the floor of the floor may cause scratches and the like. For this reason, when cleaning in the home, it is ideal that the hand control tube 3 and the expansion joint tube 4 are not lowered on the floor or the like but are standing.

  FIG. 4 is a perspective view of the hand-held handle 21. The original purpose of the hand-held handle 21 is to use the cleaner body 1 by lifting the cleaner body 1 to a place where there is a step, such as a staircase, or when cleaning a high place (fluorescent lamp or the like). Although the hand-held handle 21 is not usually used for cleaning, it is often used in a special way, particularly when the vacuum cleaner body 1 is lifted up, and is made of a very hard material as a part. The hand-held handle 21 is connected to the cleaner body 1.

  FIG. 5 is a perspective view of the expansion joint pipe 4. The expansion / contraction joint pipe 4 can be freely expanded and contracted, and is roughly divided into two parts, an expansion joint outer pipe 4a and an expansion joint inner pipe 4b. The expansion joint outer pipe 4a and the expansion joint inner pipe 4b are connected, and the length can be adjusted by sliding while accommodating the expansion joint inner pipe 4b in the expansion joint outer pipe 4a. In addition, the length may be adjustable by connecting the expansion joint outer pipe 4a and the expansion joint inner pipe 4b separated in the storage form instead of the slide in the usage form. One end of the expansion joint outer pipe 4 a can be connected to the hand operating pipe 3, and one end of the expansion joint inner pipe 4 b can be connected to the suction port 5. Moreover, it is preferable that the expansion joint pipe 4 is extended in the usage mode and contracted in the storage mode. In other words, the expansion joint pipe 4 is longer in the usage form than in the storage form, and thus the stability is deteriorated.

  FIG. 6 is a vertical view of the left side view of the expansion joint pipe 4. The expansion joint pipe 4a of the expansion joint pipe 4 is provided with a hose stand a4c that can be engaged with the vacuum cleaner body 1 for compact storage when the vacuum cleaner body 1 is stored. For example, the hose stand a4c is L-shaped (a claw extending toward the suction port 5) having an opening on the suction port 5 side, and is provided on the suction port 5 side on the expansion joint outer pipe 4a. The vacuum cleaner main body 1 has a portion that engages with the hose stand a4c (not shown), and is used when the stand is stored (stored). The locking part on the cleaner body 1 side is, for example, a shape that is provided on the upper surface, side surface, or bottom surface of the cleaner body 1 and opens to the hose edge 5 side (vertically upward side in the storage form). Similarly, a hose stand b4d, which is a part for locking the expansion joint pipe 4b of the expansion joint pipe 4, is also provided. For example, the hose stand b4d is L-shaped (a claw extending toward the suction port 5) having an opening on the suction port 5 side similarly to the hose stand a4c, and is provided on the suction port 5 side on the expansion joint inner pipe 4b. That is, the expansion joint pipe 4 is provided with two hose stands, which are locked to the cleaner body 1 using a hose stand b4d close to the suction port 5 in the usage form, and a hose stand close to the hand operation pipe 3 in the storage form. It is preferable to be locked to the cleaner body 1 using a4c. Further, the position on the circumference of the expansion joint pipe 4 of the hose stand a4c and the position on the circumference of the expansion joint pipe 4 of the hose stand b4d are approximately the same, that is, the same direction on the expansion joint pipe 4 It is preferable that it exists in. Note that the hose stand may be one of the hose stands 4d of the expansion joint inner pipe 4b as long as it can be used in both the usage form and the storage form.

  FIG. 7 shows a front view of the hand-held handle improvement 22. Compared to the hand-held handle 21, the hand-held handle improvement 22 includes a handle locking portion a23, a handle locking portion b24, and a handle roller 25 having a roller. The handle locking part a23 and the handle locking part b24 are composed of two locking parts, a handle locking part a23 locked to the hose stand b4d and a handle locking part b24 having the same action on the target side. The handle locking part a23 and the handle locking part b24 have, for example, a shape having an opening in the upward direction, and are provided on the uppermost part of the handheld handle improvement 22. That is, the handle locking part a23 and the handle locking part b24 are provided above the hose penetration part of the handheld handle improvement 22. The position of the upper end of the hand-held handle improvement 22 is preferably the same as or lower than the position of the upper end of the cleaner body 1. Therefore, in this case, the handle locking portion a23 and the handle locking portion b24 are approximately the same as or lower than the position of the upper end of the cleaner body 1. Moreover, it is preferable that the handle engaging part a <b> 23 and the handle engaging part b <b> 24 are provided at a position higher than the center of gravity of the cleaner body 1 and at a position higher than the center point of the cleaner body 1. And while using the vacuum cleaner, the user inserts the hose stand b4d of the expansion joint pipe 4 into one of the handle locking part a23 or the handle locking part b24 from above, in a room or a living room. When cleaning, even if there is an obstacle such as a table, the obstacle can be moved as it is being cleaned, and the suction port and the expansion joint tube are not placed on the floor, so that the person can stand and sit Occurrence of low back pain or the like caused by a burden on the waist and knees due to movement is eliminated. By forming the handle locking portion a23 and the handle locking portion b24 on the hand-held handle improvement 22 that can be manufactured separately from the cleaner body 1 instead of the cleaner body 1, the handle locking portion a23 and the handle locking portion are formed. Manufacture and attachment of the part b24 are facilitated.

  FIG. 8 shows a top view of the hand-held handle improvement 22. The hand-held handle improvement 22 is preferably shaped so that the side surface of the hand-held handle 21 extends rearward from the hand-held handle 21 so as to cover the vacuum cleaner body 1. It is possible to protect against collisions. In addition, since the handle roller 25 is added to the lower part of the hand-held handle improvement 22, the rotating performance of the cleaner body 1 is improved. The position of the handle roller 25 is preferably on the rear side of the cleaner body 1 with respect to the handle locking portion a23 and the handle locking portion b24. Further, wheels or smooth moving parts may be added to the handle roller 25 instead of the rollers. Thereby, when the hose stand b4d of the expansion joint pipe 4 is inserted into the handle locking part a23 of the handheld handle improvement 22 or the handle locking part b24 and after the insertion (at the time of locking), the vacuum cleaner main body 1 or the like is collapsed. Can be suppressed. That is, stability can be improved.

  FIG. 10 is an enlarged view of an improved expansion joint pipe and hand handle in a locked state. The front view of the hand-held handle improvement 22, the expansion joint pipe 4, and the suction mouth 5 are actually locked. The handle locking part a23 and the handle locking part b24 are provided above the hose joint 2a. In this way, the position where the handle locking portion a23 and the handle locking portion b24 are higher than the connecting portion (hose joint 2a) of the hose 2, that is, the locking position (hose stand a4c and hose stand b) is the locked object. A stable hose because the hose 2, the hand control pipe 3, the expansion joint pipe 4, the position near the center of gravity of the suction mouth 5, or the position closer to the hand control pipe 3 than the suction mouth 5 on the expansion joint pipe 4 Is obtained. Further, it is preferable that the side surface of the hand-held handle improvement 22 extends in the vertical direction when viewed from the front of the cleaner body 1 and has a square shape. That is, it is preferable that a part of the suction port 5 is in contact with the side surface of the hand-held handle improvement 22 at the time of locking. This increases the number of contact points between the object to be locked (hose 2, hand control pipe 3, expansion joint pipe 4, suction port 5) and the vacuum cleaner main body 1, so that the locking of the locked object is stable during locking. Can be improved. Furthermore, it is preferable that the side surface of the hand-held handle improvement 22 has a shape along the shape of the side surfaces of the expansion joint pipe 4 and the suction port 5 at the time of locking. This further increases stability. In addition, the hose stand b4d of the expansion joint pipe 4 is engaged with the handle locking portion a23 or the handle locking portion b24 in the direction in which the front-rear direction of the cleaner body 1 and the movable direction of the suction port 5 intersect (preferably 90 degrees). It is preferable to provide a hose stand b4d on the expansion joint pipe 4 so as to be stopped.

  A relatively soft material such as popipropylene (PP) is used for the hose stand a4c and the hose stand b4d. As a result, the hose stand a4c and the hose stand b4d are not easily damaged even when a sudden force is applied from the side surface as well as a normal use state. The hand-held handle improvement 22 is made of a slippery and hard material such as acrylonitrile butadiene styrene (ABS). As a result, even if a great amount of force is applied, it is difficult to break.

  Further, a circuit (for example, a switch) for turning off the power of the vacuum cleaner is provided in the handle locking part a23 and the handle locking part b24, and the handle locking part a23 of the handheld handle improvement 22 or the handle locking part b24 is provided. The power source of the vacuum cleaner may be turned off in conjunction with the insertion of the hose stand b4d of the expansion joint pipe 4. As a result, when the telescopic joint pipe 4 is inserted into the hand-held handle improvement 22, the power of the vacuum cleaner is automatically turned off, so that the convenience of the user can be improved and unnecessary power consumption can be reduced. The vacuum cleaner may be turned on in conjunction with the removal of the hose stand b4d of the expansion joint pipe 4 from the handle locking part a23 or the handle locking part b24 of the hand-held handle improvement 22, Even if the hose stand b4d of the expansion joint pipe 4 is taken out from the handle locking part a23 or the handle locking part b24 of the handle improvement 22, it is not necessary to turn on the power of the vacuum cleaner (it remains OFF). When the power source of the vacuum cleaner is not turned on, the user can turn on the power source of the vacuum cleaner by operating a power switch installed on the hand control tube 3.

  FIG. 9 is an external perspective view of the vacuum cleaner used in the present invention.

  A feature is that a crucible and a brush 30 are provided at an end of the expansion joint pipe 4 on the suction port 5 side, and a hose stand similar to that of the first embodiment is provided on the crucible and the brush 30. The crucible and the brush 30 have a brush and are rotatable.

  As a result, the same locking portion is also added to the crucible and the brush 30, so that the same effects as those of the first embodiment can be obtained even when the crucible and the brush 30 are present. As another example, a handle latching portion a23 and a handle latching portion b24 are provided at a position higher than the hose 2 of the vacuum cleaner main body 1 in the usage form, instead of or together with the telescopic joint inner pipe 4b.
