Such a dust hose is flexible to the user's pushing out of the suction port, and can be extended and followed, and the relaxation is eliminated by the force to be reduced, so that the unused length is not revealed. It does not interfere.

On the other hand, when the user cleans the bottom surface, the user reciprocates the bottom suction port body back and forth on the bottom surface. At this time, the vacuum cleaner moves the cleaner main body so as to follow the user who moves the cleaning location in sequence.

At this time, the rigidity of the dust collecting hose connecting the suction inlet body and the cleaner body greatly influences the ease of use of the suction inlet body. The dust collecting hose serves as a connecting member for pulling the cleaner main body in accordance with a user who moves the cleaning point in sequence. In this role, the dust collecting hose is flexed and curved, but is not stretched very much to maintain its length, and it is required to pull the cleaner main body closer to the user.

That is, the dust collecting hose can be compatible with the different properties (easy to stretch, difficult to stretch) when it faces the tube end of the vacuum cleaner at a high cleaning place and when the bottom suction port is used. desirable.

Therefore, an object of the present invention is to provide an electric vacuum cleaner which can improve the ease of use by changing the elasticity of the dust collecting hose according to the use situation.

7 is a perspective view showing a part of the vacuum cleaner according to the embodiment of the present invention.

8 is a side view showing a part of the vacuum cleaner according to the embodiment of the present invention.

As shown in FIG.7 and FIG.8, the electric vacuum cleaner 1 which concerns on this embodiment is the flexible dust collecting hose 21 which connects the electric blower 8 and the handle operation pipe 22 (relay tube) in communication. (1st dust collecting hose), the handle operating pipe 22, and the suction inlet body 35 are connected, and the 2nd dust collecting hose 85 which is more flexible than the dust collecting hose 21 is provided.

Moreover, the vacuum cleaner 1 is equipped with the telescoping tube 86 of the telescopic structure which can be telescopically connected, and the 2nd dust collecting hose 85 and the suction port 35 are connected.

Compared with the dust collection hose 21, the 2nd dust collection hose 85 is easy to extend | stretch from natural length, and is easy to shrink | contract from the extended state. In other words, the second dust collecting hose 85 has a property similar to that of the tension spring that has a spring constant lower than that of the dust collecting hose 21 and is reduced to the end by shrinkage force to a natural length.

Moreover, the 2nd dust collecting hose 85 is equipped with the joint pipe 87 which can be fitted to the handle operation pipe 22 in one end part (downstream side), and the expansion pipe 86 in the other end part (upstream side). The joint pipe 88 can be fitted.

The joint pipe 88 is provided with the lock mechanism 89 which fixes and disengages the elastic pipe 86 which was inserted.

Moreover, the 2nd dust collecting hose 85 is in the upstream of the airflow which the electric blower 8 intakes compared with the dust collecting hose 21. As shown in FIG.

The vacuum cleaner 1 is used for extensively cleaning the floor surface in the form of connecting the extension tube 25 and the bottom suction port 26 to the upstream side of the handle operating tube 22 shown in FIG. 1. Suitable. The vacuum cleaner 1 of this embodiment absorbs the operation of the user reciprocating the handle operation tube 22, the extension tube 25, and the bottom suction port 26 integrally back and forth by the overall deflection of the dust collecting hose 21. do.

Then, when the user pulls the handle operation tube 22 to change the cleaning location, the vacuum cleaner 1 pulls the vacuum cleaner main body 2 with the dust collecting hose 21 which maintains its length while being straight even though the bending is eliminated. To a new cleaning location. That is, when the bottom suction port 26 is used, the dust collecting hose 21 is preferably easily bent and curved (low bending rigidity), while in order to tow without damaging the followability of the cleaner body 2. It is desirable not to stretch easily (high vertical rigidity).

Therefore, the dust collecting hose 21 is difficult to stretch and contract as compared to the second dust collecting hose 85, maintains the followability of the cleaner main body 2, and improves operability.

On the other hand, in the form which connects the 2nd dust collecting hose 85, the expansion pipe 86, and the suction port 35 to the upstream side of the handle operation pipe 22 as shown in FIG. For example, it is suitable for the use of narrow cleaning parts, such as a clearance of a furniture and a bed, or a cleaning point which is difficult to identify with the naked eye in high places, such as the upper surface of the indoor unit of an air conditioner, such as an air conditioner.

In the vacuum cleaner 1 used in this embodiment, the user can move the expansion pipe 86 and the suction port 35 integrally in any direction, and the second dust collecting hose 85 is more flexible than the dust collecting hose 21. It is supposed to be absorbed by the warpage of.

Then, the vacuum cleaner 1 is displaced by the second dust collecting hose 85 that extends linearly and easily even when the user pulls the expansion and contraction tube 86 in order to change the direction of the tube end (suction opening 35). Absorbs and maintains the position of the cleaner main body (2).

That is, in the case of using the suction port 35, the second dust collecting hose 85 is preferably easily bent and curved (low bending rigidity), and is easily stretched (low vertical rigidity) to the cleaner body ( It is preferable that the position of 2) can be maintained.

Accordingly, the second dust collecting hose 85 is easily bent between the handle operating tube 22 and the suction inlet 35, or is easily elongated to permit large displacement between the two parts of the cleaner body 2 while allowing the second dust collecting hose 85 to be easily stretched. It improves operability by making it easy to maintain position.

In particular, since the second dust collecting hose 85 is located on the upstream side closer to the tube end (suction inlet 35) than the dust collecting hose 21, the user performs the operation of pulling the expansion pipe 86 in the second dust collecting hose ( It can be absorbed by using 85) side principally.

In addition, compared to the dust collecting hose 21, the second dust collecting hose 85 can be flexibly bent in an operation of pushing the suction inlet 35 further away, and can also be extended and followed, and to be reduced. Relaxation is eliminated by force, and the unused length is not revealed and does not disturb the user.

The expansion pipe 86 can be expanded in multiple stages, for example in three stages. The expansion and contraction pipe 86 is provided with the joint part 91 which can be fitted and connected to the joint pipe 88 of the 2nd dust collecting hose 85 in one end part (downstream side), and a suction inlet body in the other end part (upstream side). The joint part 92 which can fit and connect 35 is provided.

In addition, the expansion and contraction tube 86 is provided with a lock mechanism 93 for fixing and releasing the extended state or the shortened state at each end.

In addition, the vacuum cleaner 1 can provide not only the suction port 35 but the cleaning end part 86 and the opening end part of the upstream side of the 2nd dust collector hose 85 for cleaning | cleaning as a cylinder end.

9-11 is a figure which shows an example of the use state of the suction inlet body which concerns on embodiment of this invention.

As shown in FIG. 9, the vacuum cleaner 1 which concerns on this embodiment connects the 2nd dust collecting hose 85, the expansion pipe 86, and the suction port 35 to the handle operation pipe 22 one by one. In the bottom suction port 26, cleaning of a location that is difficult to clean, for example, a high place, can be performed.

The user of the vacuum cleaner 1 grips the downstream side (an end portion close to the second dust collecting hose 85), which is the source of the expansion pipe 86, lifts the suction port 35 upward and cleans the high place. Do it. As a specific example of the cleaning point in a high place, when considering the upper surface of the indoor unit ie of the air conditioner, the average height of the woman (assuming about 158 cm) is set by setting the longest length of the expansion pipe 86 to about 1 m. Even a user whose height is about several centimeters to several ten centimeters smaller can reach the suction port 35 at the location.

In addition, the height of the ceiling surface of the indoor unit ie of the air conditioner is about 25 cm to about 30 cm in height when the indoor unit of a height of about 25 cm is spaced apart by a slight distance (about 10 cm) above the sweeping window of about 2 m in height. It is assumed to be between 2 m 35 cm and about 2 m 40 cm.

As shown in FIG. 10, the suction inlet 35 according to the embodiment of the present invention is bent by the joint 39 so that the suction 37 is located on the side of the column formed by the pipe 38. Greeting card). The inlet port 35 of the form located on the side of the heat angle is located at a position higher than the viewpoint of the user of the vacuum cleaner 1, such as the upper surface of the indoor unit of the air conditioner, for cleaning of a location where direct visual confirmation is difficult. Suitable.

The user of the vacuum cleaner 1 can easily reach the suction port 35 at the cleaning location by extending the expansion and contraction pipe 86 from an appropriate position spaced in the horizontal direction with respect to the cleaning location.

In addition, as shown in FIG. 11, the suction port 35 according to the present embodiment includes the joint 39 by rotating the suction body 37 around the rotation centerline C in an unfolded state in addition to the form located on the heat angle side. Can extend the length of the arm. The suction port 35 of the form + development form located on the side of the heat angle can reach the inner side of the cleaning location where direct visual confirmation is difficult.

For example, if the length in the longitudinal direction of the suction body 37 is set to about 17 cm, it is possible to secure the arm length of the deployed state based on the joint 39 to 30 cm or more, thereby providing an air conditioner. It is possible to clean the upper surface of the indoor unit to the wall side (the suction body 37 of the double-dot chain line in FIG. 9).

In this way, the suction port 35 according to the present embodiment moves linearly (one-dimensional) along the edge of the cleaning location at a high position by the joint 39 bending the pipe 38 to move the edge vicinity. Not only can it be cleaned, but by deploying the suction body 37, the cleaning range can be expanded to reach the inner side from the edge portion in a planar (two-dimensional) manner.

12 and 13 are diagrams showing an example of a state of use of the inlet port according to the embodiment of the present invention.

As shown in FIG. 12, the suction inlet 35 according to the present embodiment is bent by the joint 41 so that the suction 37 is located on the right angle side formed by the pipe 38 to be flipped backward. .

The suction inlet 35 of the form (returned back form) located in this right angle side is suitable for the cleaning of the cleaning location where the bottom suction port 26 is hard to enter and is narrow like a clearance of a furniture, for example. The user of the vacuum cleaner 1 can easily reach the suction port 35 at the cleaning location by extending the expansion and contraction pipe 86 from an appropriate position spaced in the horizontal direction with respect to the cleaning location.

The suction inlet 35 positioned on the right angle side has a joint 41 in the parallel portion 55 of the suction 37 and the pipe 38 to avoid the suction port 35. The force pressurized on the cleaning surface can be easily transmitted to the entire suction body 37, and the cleaning surface can be wiped out reliably.

By the way, in the conventional suction port, since the positioning of the bending of the connection pipe was fixed, if the height of the grip position changes according to the shaking of the user's arm, the suction body (or the tip of the brush) is spaced apart from the surface to be cleaned or grounded. May become unstable.

On the other hand, in the inlet port 35 according to the present embodiment, since the margin of the at least one other positioning position 43b is large in the positioning mechanism 43 of the joint 41, Even if the height change of the accompanying gripping position occurs, it is possible to shake the suction body 37 with respect to the expansion pipe 86 and the pipe portion 38, so that it is easy to maintain the ground, and the dust on the surface to be cleaned It can be swept away.

In addition, as shown in FIG. 13, the suction inlet body 35 according to the present embodiment extends from the joint 39 by rotating the suction body 37 around the rotational centerline C in an unfolded state in addition to the rearward form. Length can be increased.

The suction port 35 thus formed in the retracted form + the retracted form can reach the inner side of the narrow cleaning point. In addition, the suction inlet body 35 in the form of a back-flip + development can be cleaned by allowing the suction body 37 to enter a narrow space up and down, such as below the television die.

14 is a view showing an example of a use state of the electric vacuum cleaner according to the embodiment of the present invention.

As shown in FIG. 14, the suction inlet body 35 according to the present embodiment bends the joints 39 and 41 appropriately so that the suction inlet body 35 is restricted to a narrow gap in the height direction. Can be easily reached.

For example, it is suitable for the cleaning of a narrow place with a low ceiling surface like the clearance gap between the storage boxes stored under the bed B. For example, as shown in FIG. The user of the vacuum cleaner 1 can easily reach the suction port 35 at the cleaning location by extending the expansion and contraction pipe 86 from an appropriate position spaced in the horizontal direction with respect to the cleaning location.

The vacuum cleaner 1 which concerns on this embodiment is equipped with the 2nd dust collecting hose 85 which curves more flexibly than the dust collection hose 21, and is the inlet port 35, the expansion pipe 86, and the 2nd dust collection apparatus. When cleaning at the open end of the upstream side of the hose 85, the process of these cylinder ends becomes easy, and operability can be improved.

In addition, when the vacuum cleaner 1 removes the 2nd dust collecting hose 85 and connects the extension pipe 25 and the bottom suction port 26 to the dust collecting hose 21, the 2nd dust collecting hose 85 is carried out. The followability of the cleaner main body 2 can be matched according to the property of the dust collecting hose 21 irrespective of the property of).

Moreover, the vacuum cleaner 1 which concerns on this embodiment reduces the followability of the vacuum cleaner main body 2 by providing the 2nd dust collection hose 85 which is easy to extend from a natural length compared with the dust collection hose 21, and is positioned. It is easy to hold | maintain, and it is easy to direct a cylinder tip to a suitable direction, without minding following of the cleaner main body 2. As shown in FIG.

As a result, the vacuum cleaner 1 can reduce the risk of pulling the cleaner main body 2 and colliding with the furniture or the like while being deprived of the user's narrow cleaning point or high cleaning point.

Moreover, since the vacuum cleaner 1 which concerns on this embodiment is easy to change the direction of the base part of the expansion pipe 86 which is the part which a user grips by providing the expansion pipe 86, It is easy to reach the distal end of the suction port 35 and the expansion pipe 86 at a farther cleaning location.

Therefore, according to the vacuum cleaner 1 which concerns on this embodiment, the elasticity of the dust collecting hoses 21 and 85 can be changed according to a use condition, and the usability can be improved.
