Description

Electric vacuum cleaner {VACUUM CLEANER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric vacuum cleaner that allows a user to arbitrarily select a rotation angle of an intake body by operating a handle handle body. In particular, the invention relates to a vacuum cleaner for rotating the intake body by manipulating the handle handle body. The present invention relates to a structure around a handle handle so that the presence of the suction hose is not prevented when the presence is not disturbed or when cleaning a low height place.

In vacuum cleaners, connection means are generally provided in the inlet body to which the connecting pipe (extension pipe) is connected to the handle handle body. And in the conventional vacuum cleaner, the horizontal movement form suitable for normal cleaning (cleaning of a large place) with which the inlet body moves in parallel with the width direction with the linear back and forth movement of a connection pipe (knob handle body) is called Is referred to as a first movement type, but a vertical movement type suitable for cleaning near the wall where the inlet body moves in parallel with its longitudinal direction is accompanied by a straight forward and backward movement of the connecting pipe. (Hereinafter, referred to as a second moving mode), it is not considered very much, and there is a problem in operability of cleaning such as near the wall.

Thus, the applicant of the present application in the Japanese Patent Application Nos. 9-141374, 9-359272, and 10-67112, the first and second movement forms described above by the torsional operation of the grip part of the handle handle body. A vacuum cleaner has been proposed to facilitate taking.

In each said source, the 1st connection pipe which connects the connection pipe member provided in the inlet body to the intake main body rotatably, and performs the longitudinal rotational movement along the inside of a vertical plane, and this 1st connection pipe It is rotatably connected to the second connector consisting of a second connecting pipe that rotates in the left and right directions along a plane perpendicular to the vertical plane, and maintains the inlet body in close contact with the bottom by the twisting operation of the grip portion of the handle handle body The shape is easily changed from the first moving form to the second moving form or from the second moving form to the first moving form.

By the way, in the above-described vacuum cleaner, in which the suction body obtains the first and second movement forms by the twisting operation of the grip portion of the handle body, the grip portion and the cross section of the handle body Since the tubular part respectively connected to the suction hose and the connection pipe is integrated, the suction hose connected to the tubular part also moves together with the tubular part when the grip part of the handle handle body is twisted, so that the suction hose is wound around the body. There is a case to be disturbed. That is, as shown in (b) of FIG. 8, when the grip part of the handle handle body is twisted horizontally and the inlet body takes the 2nd movement form, the connection part with the handle handle body in a suction hose is also lifted horizontally. This causes a problem that the suction hose is wound around the user's body and thus is disturbed. Alternatively, in the case where the inlet body takes the first moving form and is cleaned in a place where the height is low, such as under a bed, as shown in FIG. There is a problem that it is not possible to lay the connection pipe close to horizontal by the height of the suspended suction hose.

So, in the Japanese Patent Application No. 9-314795, the applicant applies a tubular portion bent in the shape of a handle to the handle handle body, and installs the connecting tube piece so as to be rotatable on the outer peripheral portion where the main surface opening is provided in the tubular portion. The structure which connected the suction hose to the pipe piece was proposed. In the technique proposed in Japanese Patent Application Laid-Open No. 9-314795, since the connecting pipe piece connecting the suction hose with respect to the tubular portion of the handle handle body is rotatable, the grip portion of the handle handle body is moved horizontally to move the second to the inlet body. Even in the case of taking the shape, the connection piece is relatively rotated by the weight of the suction hose, so the suction hose can be kept suspended downward, and the suction hose is positioned horizontally on the handle by rotating the connection piece by hand. It is also possible to bend the tube and bend the tube close to horizontal.

However, in the technique proposed in Japanese Patent Application No. 9-314795, it requires a connection pipe piece having a shape divided into two, increasing the number of parts, complicated the shape of the tubular portion of the handle handle body, and the complicated assembly, which leads to increased cost. There is a problem that the weight reduction of the handlebar body is also hindered. Furthermore, there is a problem that the suction passage near the handle handle becomes complicated, impairs the ventilation efficiency, and is easy to generate noise.

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and an object thereof is to provide a vacuum cleaner in which a user can arbitrarily select a rotation angle of an air intake body by operating a handle body. It is simple and easy to assemble and also has good aeration efficiency and noise suppression so that the presence of the suction hose is not obstructed when the rotary hose is rotated or the location of the suction hose is not obstructed when cleaning the low place. This is to make it excellent to realize.

It transmits to the light receiving part of the vacuum cleaner main body 1 using reflection.

In addition, the second tubular body 32 rotatably connected to the first tubular body 31 has a central axis A3 coinciding with the central axis A2 of the first tubular body 31, as shown in FIG. And the second connecting portion bent downward from the first connecting portion 34 so as to form a predetermined angle with the central axis A3 of the first connecting portion 34 (that is, the central axis A2 of the first tube body 31). 35). In addition, in FIG. 5, B1 is the central axis of the second connecting portion 35.

And the 1st connection part 34 of the 2nd tubular body 32 is inserted in the 1st tubular body 31 so that relative rotation is possible, and also the 1st connection part 34 of the 1st tubular body 31 and the 2nd tubular body 32 is carried out. ) Is connected so as not to fall out by a suitable means, and the 1st connection part (2nd tubular body 32) is comprised so that the circumference | surroundings of the center axis A2 of the 1st tubular body 31 can be rotated. In addition, although the coupling | bonding prevention means of the 1st connection part 34 of the 1st tubular body 31 and the 2nd tubular body 32 can employ | adopt an arbitrary thing, in this embodiment, as shown in FIG. The annular groove 36 is provided in the 34, the first connecting portion 34 is inserted into the first tube 31, and then the anti-separation piece 38 is removed from the opening 37 of the first tube 31. By inserting a part into the annular groove 36, the 1st connection part 34 and the 1st tubular body 31 are connected so that it may not come out. In addition, by detachably installing the fall prevention piece 38, the fall prevention piece 38 is removed and the first pipe body 31 and the second pipe body 32 are removed during maintenance such as when dust is accumulated inside the pipe. It can be disassembled simply.

In addition, as shown in FIG. 4, an end portion of the suction hose 2 is provided with a connecting ring 21, and the connecting ring 21 is attached to an end portion of the second connecting portion 35 of the second tubular body 32. The 2nd connection part 35 and the suction hose 2 are connected by inserting. In addition, 21a is a locking part of the connection ring 21, and 35a is a locking part of the 2nd connection part 35. As shown in FIG. By the so-called snapping engagement of the locking portion 21a and the locking portion 35a, the second connecting portion 35 and the suction hose 2 are coupled so as not to be pulled out.

In addition, in the present embodiment, the end of the suction hose 2 is held rotatably by means suitable for the connecting ring 21, and as a result, the suction hose 2 is the second connecting portion of the second tubular body 32. In the state connected to 35, the suction hose 2 is comprised so that relative rotation with respect to the 2nd connection part 35 may be carried out. Thereby, torsion of the suction hose 2 can be prevented.

As shown in FIG. 6, the 1st tubular body 31 and the 2nd tubular body 32 are joined together, and the knob handle body 3 is completed, and the suction hose 2 and the connection pipe 4 are attached to the knob handle body 3. As shown in FIG. ), The center axis A3 of the first connecting pipe 34 (that is, the center axis A2 of the first pipe body 31 = the center axis A1 of the connecting pipe 4) and the center of the second connecting part 35. The angle β with the axis B1 (that is, the central axis of the end of the suction hose 2) is set to be 90 ° to 150 °. The reason for doing this is that the suction hose 2 is always hung obliquely downward when the user stands up while holding the holder portion 33a of the grip portion 33 of the handle handle 3 at the time of cleaning. In order to easily stretch and move the cleaner main body 1, and also to hold the holder part 33a of the grip part 33 so that a hand may not be disturbed.

7 shows the cross section of the holder part 33a of the grip part 33 of the handle handle 3, and as shown in the figure, the cross section of the holder part 33a is round and formed in substantially inverted triangle. have. The reason for doing this is to make it easy to hold when the user holds the holder part 33a by hand, and to always sense the bottom part of the holder part 33a with a tactile sense, and to grip part 33 (holder part 33a). This is to make it easy to recognize the torsional state and the neutral state of the sensor by touch.

Next, the operation of the present embodiment will be described.

Now, when the inlet body 5 takes the above-described first movement mode, the grip portion 33 (holder portion 33a) of the handle handle body 3 is twisted about 90 degrees to the inlet body 5. It takes the said 2nd movement form mentioned above. That is, as shown in FIG. 3, the grip part 33 is twisted (rotated) about 90 degrees in the direction of arrow R1, and the state of the inlet body 5 is shifted from a 1st movement form to a 2nd movement form. At this time, the first tubular body 31 and the second tubular body 32, which are integral with the grip part 33, are connected to each other so that relative rotation is possible, and furthermore, the self-weight of the suction hose 2 connected to the second tubular body 32 is Since the grip portion 33 rotates in the direction of the arrow R1, the rotational moment in the direction of the arrow M1 acts on the second tube 32 due to the weight of the suction hose 2. 32 maintains the original rotation position so that the suction hose 2 is also not lifted and maintains the original state.

Therefore, as shown in Fig. 8A, even when the grip portion 33 of the handle handle 3 is laterally twisted so that the inlet body 5 takes the second movement form, the suction hose 2 The connection part with the handle body 3 of the handle is not lifted, and the suction hose 2 remains suspended under the handle body 3 so that the suction hose 2 is not wound around the user's body. It is easy to use.

In addition, in the present embodiment, when the inlet body takes the first moving form and is cleaned in a place where the height is low, such as under a bed, as shown in Fig. 9A, the second tube 32 is removed. 90 degrees by hand with respect to the 1st tubular body 31 can be made into the substantially horizontal state which made the suction hose 2 connected to the knob handle body 3 into the substantially same height as the 1st tubular body 31. As a result, the connecting pipe 4 can be laid in a substantially horizontal state, and the housewife can be easily cleaned at a place having a low height, and the use is convenient even at this point.

In addition, in this embodiment, since the suction hose 2 can be rotated with respect to the 2nd tubular body 32, the suction hose 2 is prevented by the case where the suction hose 2 was twisted at the time of storage, a deliberate operation, etc. Even when twisting, the suction pipe 2 rotates together when the second tube 32 rotates, and the suction hose 2 can be easily returned to the state without distortion as shown in FIG. Done.

In the present embodiment, the center of the holder portion 33a of the grip portion 33 is positioned on the extension line of the central axis A1 of the connecting tube 4, and the holder portion 33a and the connecting tube ( Since the second tube body 32 (suction hose 2) is rotatable with respect to the center axis A1 between 4), the operability of the twisting operation of the handle handle 3 is not burdened with the wrist. Can be made favorable. Furthermore, as a means for realizing such a structure, between the holder portion 33a and the first tube 31 located on an extension line of the central axis of the connecting tube 4 (first tube 31), A structure in which the number of parts is small and easy to assemble is adopted to rotatably join the second pipe body 32 holding the end of the suction hose 2 with respect to the central axis A1. In addition, as long as it is the structure of the simple handle handle 3, the bent part of the suction passage to the whole handle handle 3 can also be smoothly bent in one place, and can reduce aeration resistance and air leakage. have.

Furthermore, by matching the rotation axis of the 1st connection part 34 of the 2nd tubular body 32 with respect to the said central axis A1 with the said central axis A1, the relative of the 2nd tubular body 32 to the torsional motion of the knob handle body 3 is carried out. The followability of rotation can be improved. That is, in this embodiment mentioned above, since the center axis of the 1st tubular body 31 and the center axis of the 1st connection part 34 of the 2nd tubular body 32 match with the center axis of the connecting pipe 4, The rotation moment of the first tubular body 31 eliminates the frictional resistance between the cylindrical surfaces with the twisting of the grip portion 33, and does not act at all on the first connecting portion 34 (the second tubular body 32). The followability of the relative rotation of the second tubular body 32 with respect to the twisting operation of the knob handle body 3 becomes excellent.

Here, although the rotation axis of the 1st connection part 34 of the 2nd tubular body 32 is good to match with the said filling core A1, it can use even if it inclines in the range within 0 degree to 30 degree of coincidence. That is, depending on the case, even if it is comprised so that the rotation moment of the 1st tubular body 31 may act to the 1st connection part 34 (2nd tubular body 32) to some extent, there is no practical problem. That is, the center axis line of the 1st tubular body 31 is bent, and the center axis line of the connection part with the 1st connection part 34 in the 1st tubular body 31 is 30 degrees or less with respect to the center axis line A1 of the connection pipe 4. Even if it is inclined to the range of, there is no problem.

In addition, in the present embodiment, the rotary part corresponding to the twisting operation of the handle handle 3 and the rotary part for preventing the twisting of the suction hose 2 are provided to accompany the torsion of the suction hose 2. It is possible to reduce adverse effects, and to improve the running and suction properties of the cleaner body 1 as well.

Furthermore, the parts of the handle handle 3 can be easily attached and detached to improve the assemblability and maintainability. Although not described above, the rest of the lower case and the grip part 33 including the first tubular body 31 and the grip part 33 of the handle 3, and the first tubular body 31 and the part of the grip part 33. It is possible to further improve the assemblability by forming a portion of the upper case and disposing a circuit board or the like between the lower case and the upper case.

As described above, in the present embodiment, the number of parts can be easily reduced, assembling property is improved, and the shoes are lightly coupled to rotatably couple the second pipe body 32 to the first pipe body 31 of the handle handle 3. When the suction body is rotated by the operation of the handle body 3 by the configuration of the handle body 3 as much as possible, when the presence of the suction hose 2 is not obstructed or the place where the height is low is cleaned. The presence of the suction hose 2 can be prevented from being disturbed. Furthermore, since the suction passage bent at the handle 3 is set to one place, the ventilation efficiency and noise suppression property are also excellent.

Next, a second embodiment of the present invention will be described with reference to FIG. Fig. 10 is an exploded perspective view showing the end portions of the second tubular body and the suction hose in the handle handle body of the vacuum cleaner according to the second embodiment of the present invention.
