Description

Suction inlet and vacuum cleaner {SUCTION OPENING BODY AND ELECTRIC CLEANER}

Embodiments related to the present invention relate to a suction inlet body and an electric vacuum cleaner.

The suction port of a conventional vacuum cleaner includes a bendable tube and a T-shaped suction member rotatable in a direction different from the extending direction of the tube.

This T-shaped suction body has a rotation center line in the center of the longitudinal direction.

Japanese Patent Application Laid-open No. 2010-252999

Since the suction body of the conventional vacuum cleaner has a rotation center line in the center of the longitudinal direction, it rotates by half the rotation radius of the longitudinal length of the suction body. From this, in the conventional suction port, when the suction pipe is taken as a reference, only half of the length in the longitudinal direction of the suction body changes even when the suction body is rotated (not extended). In other words, the conventional suction port does not expand the cleaning range even if the suction body is rotated, and the reachable distance of the suction body does not change.

When cleaning the cleaning area higher than the user's gaze by using an electric cleaner that does not expand the cleaning range even when the suction body is rotated, the user grips the long pipe part, especially when the suction port reaches a farther distance. You need to extend your arms. On the other hand, by making the pipe part more elongated, it is possible to reach the inlet port further.

However, in order to reach the suction unit to a distant cleaning point, forcing the user to extend the heavy pipe portion or to extend the arm in comparison with the suction port may generate a large force, increase the load of the user, and increase the electric cleaner and the suction port. Impairs the ease of use. In particular, this tendency becomes remarkable when a place located at a considerably high place such as an indoor unit of an air conditioner is a cleaning location.

Therefore, an object of the present invention is to obtain a suction inlet body and an electric vacuum cleaner which can enlarge a cleaning location without the user making a big arm out and not affecting the length of the pipe portion connected to the suction body.

In order to solve the said subject, the suction inlet body which concerns on embodiment of this invention shifts to the any one end side from the center in the longitudinal direction of the suction body of a length-shaped inlet, and the said suction body, and opens the said suction port. A pipe part fluidly connected to the suction body through an opening located approximately coaxial with the rotation center line while rotatably supporting the suction body around a rotation center line maintaining a direction; It is characterized by having at least one joint.

Thereby, the suction inlet body which can enlarge a cleaning location can be provided, without affecting the length of the pipe part connected to the suction body.

Moreover, the vacuum cleaner which concerns on embodiment of this invention is equipped with the said suction inlet body, and the electric blower fluidly connected to the said suction inlet body. It is characterized by the above-mentioned.

Thereby, the vacuum cleaner which can enlarge a cleaning location can be provided, without affecting the length of the pipe part connected to a suction body.

The main body case 5 has a main body connector 12 as a joint that can attach and detach the pipe part 3. The main body connection port 12 is an inlet for sucking air containing dust into the cleaner main body 2, and connects the pipe part 3 and the dust separation dust collecting part 7 to communicate with each other.

The dust separation dust collector 7 separates, collects, and accumulates dust from air including dust introduced from the surface to be cleaned through the pipe part 3 and the main body connection port 12 by the negative pressure generated by the electric blower 8. Together with air is sent to the electric blower (8).

The electric blower 8 sucks air passing through the dust separation dust collector 7 to generate negative pressure.

The main body control unit 9 includes a microprocessor (not shown), and a storage device (not shown) that stores various arithmetic programs, parameters, and the like executed by the microprocessor. The main body control unit 9 stores a plurality of operation modes that are set in advance in the storage device.

The plurality of operation modes set in advance have different input values (input values of the electric blower 8) as the difference between the operation modes in response to the operation signals received from the pipe part 3.

When the main body control unit 9 receives the operation signal from the pipe unit 3, the main body control unit 9 selectively selects an arbitrary operation mode corresponding to the operation signal from a plurality of preset operation modes, reads it from the storage unit, and reads the operation mode. Therefore, operation control of the electric blower 8 is performed.

The power cord 11 has a power plug 14 at its free end.

The pipe part 3 sucks air containing dust from the surface to be cleaned and guides it to the cleaner main body 2 by the negative pressure acting from the cleaner main body 2 with the operation of the electric blower 8. The pipe part 3 communicates with the connection pipe 19 as a joint detachably connected to the cleaner main body 2, the dust collection hose 21 connected in communication with the connection pipe 19, and the dust collection hose 21.

The operation unit 24 is provided with a switch corresponding to each operation mode. Specifically, the operation unit 24 includes a stop switch 24a corresponding to the operation stop operation of the electric blower 8 and a start switch 24b corresponding to the operation start operation of the electric blower 8.

The stop switch 24a and the start switch 24b are electrically connected to the main body control unit 9. The user of the vacuum cleaner 1 can alternatively select the operation mode of the electric blower 8 by operating the operation unit 24. After the electric blower 8 starts operation, the start switch 24b also functions as a selection switch of the operation mode. In this case, each time the main body control unit 9 receives the operation signal from the start switch 24b, the main body control unit 9 switches the driving mode from high to medium to low to strong. ... ... Switch to

In addition, the operation part 24 may be provided with the weak operation switch (not shown), the heavy operation switch (not shown), and the strong driving switch (not shown) separately instead of the starting switch 24b.

The extension tube 25 is an elongate, substantially cylindrical tube that is stretchable. Extension tube 25 is composed of a telescopic (telescopick) structure that can be expanded and stretched like a passage of a telescope by overlapping a plurality of cylindrical bodies. One end portion (downstream side) of the extension tube 25 is detachably connected to the other end portion (upstream side) of the handle operating tube 22. The extension pipe 25 communicates with the dust separation dust collecting part 7 via the handle operating pipe 22, the dust collecting hose 21, and the connecting pipe 19.

The vacuum cleaner 1 starts the operation of the electric blower 8 when the start switch 24b is operated, and generates the negative pressure (suction negative pressure) inside the cleaner main body 2. For example, when the start switch 24b is operated while the electric blower 8 is stopped, the vacuum cleaner 1 first drives the electric blower 8 in the strong driving mode, and then the start switch 24b. Is operated, the electric blower 8 is operated in the medium operation mode.

In addition, when the start switch 24b is operated, the electric blower 8 is operated in the weak operation mode, and it repeats hereafter.

The strong driving mode, the medium driving mode and the weak driving mode are a plurality of preset driving modes, and the input values are smaller in the order of the strong driving mode, the medium driving mode, and the weak driving mode.

The negative pressure generated inside the cleaner body 2 is bottomed through the dust separation dust collecting part 7, the main body connecting hole 12, the connecting pipe 19, the dust collecting hose 21, the handle operating pipe 22, and the extension pipe 25. It acts on the suction port 28 of the surface suction port 26.

By the negative pressure acting on the suction port 28, the vacuum cleaner 1 sucks dust stored in the surface to be cleaned together with the air from the suction port 28 to clean the surface to be cleaned. The dust separation dust collecting unit 7 separates, collects, and accumulates dust from the air including the dust sucked by the suction port 28. The air, which has been separated and cleaned from the air including the dust, passes through the dust separation dust collecting part 7 and the electric blower 8 and is exhausted out of the cleaner body 2.

By the way, the bottom suction port 26 is suitable for cleaning a relatively large surface to be cleaned such as the floor of the living room, but, for example, air conditioners such as narrow cleaning points such as gaps in furniture or under the bed, and so-called air conditioners. It is not easy to use at the cleaning place where it is difficult to check with eyes at high places such as the upper surface of the indoor unit.

It is a perspective view which shows a part of the vacuum cleaner which concerns on embodiment of this 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 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) to communicate. The second dust collecting hose 85 which connects the 1st dust collecting hose, the handle operation pipe 22, and the suction inlet body 35, and 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 connected the 2nd dust collecting hose 85 and the suction port 35. As shown in FIG.

The second dust collecting hose 85 is easier to extend from its natural length than the dust collecting hose 21. In other words, the second dust-collecting hose 85 has a property similar to that of a tension spring having a spring constant lower than that of the dust-collecting hose 21, and a state where the shrinkage force hysteresis is completely contracted.

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). ) Is fitted with a joint pipe 88.

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 sucks 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 type 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 with the bending of the entire dust collecting hose 21. .

Then, when the user pulls the handle operation tube 22 to change the cleaning location, the electric cleaner 1 pulls the cleaner main body 2 into the dust collecting hose 21 which maintains its length while maintaining a straight line without bending. Move to a new cleaning point. That is, when the bottom suction port 26 is used, it is preferable that the dust collecting hose 21 is easily bent and curved (low bending rigidity), while it is easy to pull without damaging the followability of the cleaner body 2. It is preferable not to stretch (high final strength). Therefore, since the dust collecting hose 21 is hard to stretch compared with the 2nd dust collecting hose 85, it maintains the followability of the vacuum 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 narrow cleaning points such as furniture gaps or under the bed, or for cleaning the difficult cleaning points with high eyes such as the upper surface of the indoor unit of an air conditioner such as an air conditioner. .

The vacuum cleaner 1 used in this form allows the user to absorb the movement of the expansion pipe 86 and the suction port 35 back and forth integrally with the flexible bending and the flexible expansion and contraction of the second dust collecting hose 85. have.

The vacuum cleaner 1 absorbs the displacement by the second dust collecting hose 85 that is linear and extends in length even when the user stretches the expansion pipe 86 to change the direction of the end of the barrel (suction opening 35). The position of the cleaner main body 2 is maintained.

That is, in the case of using the suction inlet 35, the second dust collecting hose 85 is easily stretched (low bending rigidity) in addition to being preferable to bend easily (low bending rigidity), and thus the cleaner body It is preferable to maintain the position of (2).

Accordingly, the second dust collecting hose 85 is easily bent between the handle operating tube 22 and the suction port 35 and is easily extended to allow the displacement of the cleaner body 2 while permitting a large displacement between both portions. Easy to maintain, improves operability.

In particular, since the second dust collecting hose 85 is located on the upstream side closer to the end of the cylinder (suction port 35) than the dust collecting hose 21, the user performs an operation of tensioning the expansion and contraction pipe 86. 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 flexibly bend, extend, and follow the operation of extruding the suction port 35 farther, and the force to shrink By eliminating relaxation, do not create unnecessary length, do 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 equipped 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 is in the other end part (upstream side). The inlet body 35 is provided with the joint part 92 which can be fitted and connected.

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.

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

As shown in FIG. 9, the electric 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, The floor suction port 26 can clean places that are difficult to clean, for example, a high place.

The user of the vacuum cleaner 1 grasps the downstream side (an end close to the second dust collecting hose 85), which is the source of the expansion pipe 86, pushes the suction port 35 upward and cleans the high place. . 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 if the user has a height of about several centimeters to several tens of centimeters, it is possible to 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 2 m when the indoor unit having a height of about 25 cm to about 30 cm is spaced apart from a slight distance (about 10 cm) above the sweeping window having a height of about 2 m. It is assumed to be 35 cm to about 2 m 40 cm.

As shown in FIG. 10, the suction inlet 35 according to the present embodiment is formed by bending the joint 39 so that the suction 37 is located on the side of the column formed by the pipe 38. ). The suction inlet 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, for example, the upper surface of the indoor unit of the air conditioner. Suitable for cleaning

The user of the vacuum cleaner 1 can easily reach the suction port 35 at the cleaning location by extending the expansion 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 is formed in the expanded state by rotating the suction body 37 around the rotation center line C in addition to the shape located on the side of the column. Can extend the length of the arm. The suction sphere 35 in the form of a shape located at the side of the heat angle + development can reach the inner side of the cleaning part which is difficult to be visually recognized by the user.

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, and to provide an air conditioner. It is possible to clean the upper surface of the indoor unit to the wall end (the suction body 37 of the dashed-dotted line in FIG. 9).

In this way, the suction inlet 35 according to the present embodiment moves linearly (one-dimensional) along the edge of the cleaning point at a high position by the joint 39 bending the pipe 38 to move the vicinity of the edge. Not only can it be cleaned, but it can also reach the inner side from the edge part by developing the suction body 37, and can expand a cleaning range to planar (two-dimensional).

However, in the conventional suction port, since the positioning of the bending of the connection pipe was fixed, if the height of the gripping position changes with the shaking of the user's arm, the suction body (or the bristles of the brush) is spaced apart from the surface to be cleaned, Grounding condition becomes unstable.

In contrast, in the inlet port 35 according to the present embodiment, since the looseness of the other at least one positioning point 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 swing 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 is reliably wiped off. I can make it.

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 rotation centerline C in an expanded state in addition to the bending form. Arm length can be extended.

The suction port 35 made into this bending form + development can reach the inner side of the narrow cleaning point. In addition, the suction port 35 of the warp shape + the development shape can be cleaned by allowing the suction body 37 to be infiltrated into a narrow space up and down, such as under a television stand.
