  However, in patent document 1, since the front-end | tip opening part of a hand operation pipe | tube was fitted downward at the time of storage, there existed a problem which the dust which remains in a hand operation pipe | tube and a hose spilled and soiled a house.

  On the other hand, according to Patent Document 2, as can be said in Patent Document 1, since the hook portion of the hand control tube can be fixed only to a predetermined fitting portion, when the user performs compact storage, It was cumbersome to combine, and the operability was poor.

  In addition, since it is firmly fitted in the determined position, when force is applied in an unreasonable direction during removal or when the hose is touched, force is applied to the fitting part, and the fitting part is There was a risk of damage.

  SUMMARY OF THE INVENTION An object of the present invention is to address the above-described problems, to solve the problem of dust spilling, and to provide a vacuum cleaner that can be easily stored compactly, with the fitting portion of the hand control tube being hardly damaged.

  In order to achieve the above object, the invention according to claim 1 is characterized in that the cleaner body is erected with the front side of the cleaner body facing up and the rear side facing down, and the expansion / contraction extension tube faces the mouth. In a vacuum cleaner stood and housed in the vacuum cleaner main body, a hand operating tube engaging portion is provided on the hand operating tube to be engaged with an upper end opening edge of the telescopic extension tube from which the hand operating tube is removed. The hose is suspended from the expansion / contraction extension tube with the distal end of the hand control tube facing upward by the engagement of the portions.

  According to a second aspect of the present invention, there is provided an engaging portion formed with irregularities or the like on the bottom surface of the vacuum cleaner body, and an engaging portion that engages with the engaging portion is formed with irregularities or the like on the expansion / contraction extension tube. When the machine is stored, the engaging part is engaged with the engaging part, and the expansion / contraction extension tube is leaned against the cleaner body.

  The invention according to claim 3 is characterized in that the hand operating tube engaging portion is located at the tip of the hand operating tube, and has a substantially L shape with the direction of the hanging opening facing the hose.

  The invention according to claim 4 is characterized in that the hand operating tube engaging portion is slidably supported in the longitudinal direction of the hand operating tube.

  The invention according to claim 5 is characterized in that the hand operating tube engaging portion is rotatably supported by the hand operating tube.

  The invention according to claim 6 is characterized in that the hand operating tube engaging portion is provided on the side opposite to the handle portion of the hand operating tube.

  The invention according to claim 7 is characterized in that the hand operating tube engaging portion has a shape in which a hanging opening expands outward.

  The invention according to claim 8 is characterized in that the hand operating pipe engaging portion can be used also for holding the attached suction port.

  According to the first aspect of the present invention, the hose can be suspended from the expansion / contraction extension tube so that the end opening edge of the hand operation tube faces upward, thereby eliminating the problem of dust spillage. Since the hand operating tube engaging portion of the hand operating tube is turned upward and hung on the opening edge of the upper end portion of the extension / contraction extension tube, compact storage can be easily achieved.

  According to the invention of claim 4, since the hand operating tube engaging portion of the hand operating tube is slidable, the hooking portion slides and cannot be removed even when the hand operating tube is removed in an unreasonable direction. Therefore, it is possible to provide a vacuum cleaner that is easy to use.

  According to the invention according to claim 5, when the hand operating tube engaging portion for hand operation is provided so that the tube can be turned for hand operation, the hand operating tube is hooked on the tip of the expansion / contraction extension tube, and the main body is carried in error. Even when an unreasonable force is applied to the hook portion by touching the hose, the hook portion rotates and does not follow the vibration of the hose, so that the breakage of the hook portion can be reduced and a convenient vacuum cleaner can be provided.

  According to the invention of claim 6, by providing the hand operating tube engaging portion on the opposite side of the hand operating tube handle portion, even when the hose is unintentionally touched and force is applied to the fitting portion, the balance is maintained. As compared with the case where the hose is well swayed and formed on the side surface, the fitting portion is less likely to be damaged, and a user-friendly vacuum cleaner can be provided.

  According to the invention according to claim 7, since the hanging opening of the engaging portion for the hand operating tube has a shape that expands outward, when it is hooked and fixed to the end opening edge of the expansion / contraction extension tube, Even when the hose is moved unintentionally or when it is attempted to remove the hand operating tube in an unreasonable direction, the hand operating tube engaging portion is easily detached. For this reason, it is possible to provide an easy-to-use vacuum cleaner in which the hand operating tube engaging portion is not easily damaged.

  According to the eighth aspect of the present invention, since the accessory suction port can be held by the hand control tube engaging portion of the hand control tube, it is difficult for the accessory suction port to come off when touched during cleaning.

  Up until now, the attached suction port was fitted and fixed to the side of the expansion / contraction extension tube, so there was a risk that the attached suction port might come off when touched during cleaning. By holding, it becomes difficult for the attached suction mouth to come off when touched during cleaning, and a user-friendly vacuum cleaner can be provided.

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

  FIG. 2 is an external perspective view of a vacuum cleaner showing an embodiment of the present invention.

  One end of a flexible hose 101 is connected to the cleaner body 100, and the other end of the hose 101 is connected to one end of a hand operating tube 102. One end of a telescopic extension tube 103 is connected to the other end of the hand operation tube 102, and a suction port 104 is connected to the other end of the telescopic extension tube 103.

  The hand control tube 102 is provided with a switch for turning the vacuum cleaner on and off and switching the strength. In addition, the connection part is provided in the hose 101 of the side connected with the cleaner body 100, and it has the structure which connects this connection part to the cleaner body 100, and cleans.

  FIG. 1 is an external view of a vacuum cleaner when the vacuum cleaner main body 100 is stood and stored compactly. With the suction port 104 connected to the extension / contraction extension tube 103, a storage recess (engagement portion) (not shown) provided on the bottom surface of the cleaner body 100 and a projection provided to the extension extension tube. (Locking part) (not shown) can be fitted.

  Further, even when an attached brush (not shown) is attached between the expansion / contraction extension tube 103 and the suction port 104, the carrying handle 105 has a recess 106 so that the protrusion provided on the expansion / contraction extension tube 103 can be fitted. Is provided and can be stored.

  The hand operation tube 102 at the tip of the hose has a substantially L-shaped hook portion 107 (hand operation tube engaging portion), and the substantially L-shaped hook portion 107 is the distal end portion on the extension tube side of the hand operation tube 102. And is configured to open from the hand operation tube 102 toward the hose 101. The substantially L-shaped hooking portion 107 is disconnected from the hand operating tube 102 and the extension / contraction extension tube 103 and is hooked (engaged) with the end opening (end opening edge) 108 of the extension / contraction extension tube 103 for storage. be able to.

  By disposing the hooking portion 107 at the tip of the hand operating tube 102, the storage height can be suppressed and compact storage can be achieved.

  Moreover, since the opening part of the hand operation tube 102 can be hooked upward, it is considered that dust remaining in the hand operation tube and the hose is spilled and the house is not soiled. The hook 107 can be hooked in a 360-degree direction because the end opening 108 of the expansion / contraction extension tube 103 has a cylindrical shape, and is fixed to a single fitting portion determined by the user. It is designed so that it can be easily stored.

  Further, according to this configuration, even when the vacuum cleaner user is in a compact storage state in the room being cleaned and the vacuum cleaner main body 100 is carried to the room to be stored, the hook portion 107 is the end portion of the expansion / contraction extension tube 103. Since it can move in the direction of 360 degrees along the opening 108, the hook 107 is not easily detached even if the hose 101 is shaken to some extent.

  The configuration of the sliding hook that is the first embodiment of the present invention will be described with reference to FIGS. 3A, 3B, 4A, and 4B.

  The hook portion 107 is supported so as to be slidable in the longitudinal direction (front-rear direction) of the hand operation tube 102.

  3A and 3B show a case where the hand operation tube 102 and the expansion / contraction extension tube 103 are connected, and in FIGS. 4A and 4B, the attached brush 204 is connected between the hand operation tube 102 and the expansion / contraction extension tube 103. Show the case. Since the external appearance of the attached brush 204 is connected so as to cover the operation tube 102 at hand, it will come into contact if it does not slide to the hose connection side for the amount of connection.

  In the present embodiment, when the attached brush 204 is connected, the contact surface 501 of the hooking portion 107 is pushed into the external shape, and the user does not have to bother to move the hooking portion 107 back. ing.

  Also, when cleaning in the state of FIG. 3A and FIG. 3B, since the hooking portion 107 is a slide type, a spring is built in so that it does not move back and forth, and the extension operation tube side connection of the hand operation tube 102 is always provided. You may take the structure biased to the side.

  Here, as shown in FIG. 1, even when the hook portion 107 is moved to the hose connection side, if the hook portion 107 is hooked and fixed to the end opening 108 of the expansion / contraction extension tube 103, the hook portion 107 is caused to expand and contract by the own weight of the hose. It is possible to slide into the side connection side to automatically make a compact storage state in which the storage height is suppressed.

  The hook portion 107 can be more compactly accommodated if it is arranged at the tip of the hand operating tube 102 on the extensible extension tube connecting side as much as possible.

  5A, 5B, and 5C show the shape of the hook portion. The tip 502 has a large R shape so that the hook 107 can be easily inserted into the end opening 108 of the telescopic extension tube 103. Further, the inner peripheral surface 504 of the tip 502 of the hook portion 107 forms a shape along the cylindrical shape of the end opening 108 of the expansion / contraction extension tube 103, and damages the end opening 108 of the expansion / contraction extension tube 103. We consider it difficult.

  Here, a description will be given of when the hand control tube 102 is removed. FIG. 6 shows the movement when the hand control tube 102 is removed so as to be twisted. When cleaning, the user removes the hooking portion 107 from the end opening 108 which becomes the tip of the extension / contraction extension tube 103, connects the extension / contraction extension tube 103 and the hand control tube 102 to a cleaning state as shown in FIG. To do. If the operation of removing the hook 107 is performed as indicated by an arrow 601, the tip opening 108 of the extension / contraction extension tube 103 is not damaged or the hook is not damaged.

  However, it is conceivable that the user removes as indicated by an arrow 602. Therefore, the length of the front end 503 (L) of the hook portion is set so as to be detached even when it is twisted, so that it is not easily damaged.

  Further, because of the sliding hook 107, it is removed as shown by the arrow 602, and even when the hook 107 hits the tip opening 108, the hook 107 slides and hits the tip 502 of the hook 107. There is an effect to reduce the load.

  Next, the configuration of the rotary hooking portion, which is the second embodiment, will be described with reference to FIGS. 7A and 7B to 9.

  7A and 7B show the installation state of the rotary hook and the state when it is rotated. The hook portion 107 is arranged at the tip of the hand control tube 102 on the lower side (opposite side of the handle) and on the telescopic extension tube connection side as much as possible, and is fixed so as not to come off with a seated screw 701 and is rotatable. It is fixed in the state. The hand operation tube 102 is formed with a rib for restricting the rotation range of the hook portion 107, and the hook portion 107 is fixed so as to freely rotate within a predetermined angle.

  In the present embodiment, the rotation method of the hooking portion 107 is fixed by screwing, but may be fixed by nail fitting. If it is fixed by nail fitting, it is possible to eliminate the screws and simplify the assembling work.

  FIG. 8 shows a state in which the rotary hook is used to hook the end opening 108 of the telescopic extension tube 103, and FIG. 9 shows that the rotary hook is used to extend the telescopic extension tube. The movement when the hose 101 is shook by being hooked on the end opening 108 of 103 is shown.

  As described above, the hooking portion 107 can move 360 degrees along the end opening 108 of the expansion / contraction extension tube 103. Therefore, even if the hose 101 is shaken to some extent, the hooking portion 107 does not easily come off. Yes.

  However, if the rotary hook 107 is used, the hand operating tube 102 and the hook 107 can be rotated with respect to the movement of the hose 101 as indicated by the arrow 901. Can be further prevented, and a convenient vacuum cleaner can be provided.

  In addition, since the movement that causes the hand operation tube 102 to swing left and right and bend at the tip of the hook portion 107 is not transmitted, the hook portion 107 can be prevented from being damaged.

  FIG. 10 shows a time when an accessory suction port such as a clearance suction port 1001 is fixed to the hooking portion 107. Conventionally, the clearance mouthpiece 1001 and the like are often housed on the side surface of the expansion / contraction extension tube 103, but often touched and removed from the clearance mouthpiece 1001 during cleaning.

  In this embodiment, since the gap suction mouth 1001 can be fixed to the hook portion 107, it is difficult to touch the cleaner and the wall surface during cleaning, and the gap suction mouth 1001 can be prevented from coming off.

  Further, since the gap suction mouth 1001 is arranged near the hand during cleaning, the structure can be easily attached and detached even when the gap is cleaned. When storing, storing the gap suction mouth 1001 on the side surface of the expansion / contraction extension tube 103 enables compact storage using the hook portion 107.
