Japanese Patent Laying-Open No. 2015-0511117

  A lot of garbage such as spilled food is present in the lower part of the table in the dining room (table), so the lower part of the table is a place that needs to be frequently cleaned with a vacuum cleaner.

However, when the lower part of the table is cleaned with a conventional vacuum cleaner, the shape of the head portion is a T-shape or the like as described above. There is a problem that it is difficult to clean as it is because it gets in the way. Therefore, the troublesome work of moving the chair one by one is necessary at the time of cleaning, and the cleaning cannot be performed easily. In that case, even when cleaning without moving the chair, each time the head part of the vacuum cleaner is removed and the obstacle called the chair is removed, the head part is attached to the vacuum cleaner again and cleaning is performed. The same troublesome work is required. In any case, it is difficult to clean the lower part of the table comfortably and easily.

Moreover, it is not easy to put the T-shaped head portion of a conventional vacuum cleaner in a relatively narrow place such as a gap between furniture or a gap between furniture and a wall. In that case, it is possible to replace the T-shaped head part with another long and thin head part to clean the narrow space, but even in that case, the replacement work is necessary each time. The reality is that it is difficult to clean easily and comfortably.

  These problems are caused by the structure of the conventional cleaner head.

The present invention has been made based on the recognition of such a problem, and a main object thereof is to provide a cleaner head that can be cleaned comfortably by receiving obstacles in a cleaning place during cleaning.

  A vacuum cleaner head according to the subject of the present invention includes a connection pipe portion having a hollow interior space therethrough, a head having a hollow interior space connected to the interior space of the connection pipe portion, and extending in a longitudinal direction. A main body, and at least one swing head having an internal space as a hollow suction port connected to the internal space of the head main body and attached to the tip of the head main body The at least one swing head portion is positioned so as to extend in a direction substantially perpendicular to the longitudinal direction of the head body portion during normal cleaning, while the at least one swing head portion is disposed on an obstacle during cleaning. When the swing head part comes into contact, it is located in a direction substantially parallel to the longitudinal direction of the head body part with the position at the time of the normal cleaning as a base point. In and performs a swing operation to freely rotate to the left and right.

  The vacuum cleaner head according to the subject of the present invention is a relatively narrow gap, such as a furniture that cannot be inserted by a normal vacuum cleaner head, for example, when there is an obstacle such as a chair leg. When cleaning a narrow space such as a gap, the following powers or actions / effects can be achieved.

In other words, when cleaning the location of the front of the obstacle facing the cleaner head or the location of the gap between the obstacles, the swing head portion is obstructed according to the forward movement of the cleaner head. Until it is positioned in a direction substantially parallel to the longitudinal direction on the side closer to the head body (inner side) while being in contact with the head, gradually turn clockwise or counterclockwise from the position where it is disposed during normal cleaning. Rotate and swing. As a result, when the swing head portion is folded and reached to a position substantially parallel to the longitudinal direction on the head main body side, the cleaner head composed of the head main body portion and the connection pipe portion remains as an obstacle. It passes through and reaches a place in front of it or enters a gap between obstacles. In this way, the swing head part swept away the abutting obstacle according to the forward movement of the cleaner head due to the swing operation, and the cleaner head remained as an obstacle regardless of the presence of the obstacle. Pass through or get into gaps between obstacles. As soon as the cleaner head passes between obstacles, or when the cleaner head comes out of the gap between obstacles, the swing head part will turn counterclockwise or clockwise by the swing action. Rotate in one direction to return to the position at the time of normal cleaning. In this case, the swing head unit uses dust, dust, etc., in front of the obstacles passing through the obstacles, or dust, dust, etc., in the gaps between the obstacles that have entered as the suction port. Suction from the internal space to clean the area.

On the other hand, when the vacuum cleaner head that has passed between the obstacles and cleaned the front place is moved backward toward the obstacles, the swing head unit is obstructed according to the backward movement. Until it is positioned in a direction substantially parallel to the longitudinal direction on the front side (outer side) of the head main body part, one of the counterclockwise or clockwise directions from the position where it is normally cleaned. Rotate in the direction and swing. As a result, when the swing head portion is folded and reached to a position that is substantially parallel to the longitudinal direction on the front side of the head body portion, the cleaner head moves between the obstacles while moving backward. Go through without difficulty. There is no need to move or remove the obstacles. Then, as soon as the cleaner head passes between obstacles, the swing head part rotates in one direction of clockwise or counterclockwise by the swing operation, and is arranged during normal cleaning. Return to the installation position.

By the swing operation performed by the above swing head unit, the cleaner does not move the obstacles such as the chair legs or furniture at the time of cleaning, and does not remove the cleaner head from the cleaner one by one. Easily and comfortably cleans places in front of obstacles (eg under the table) or narrow gaps between obstacles (eg furniture gaps) without stress I can do it.

  Hereinafter, various embodiments of the present invention will be described in detail along with the effects and advantages thereof with reference to the accompanying drawings.

(Embodiment 1)
The cleaner head according to the present embodiment has the following characteristic points.

1) A swing head part that sucks in dust, dust and the like at the tip of the head main body part performs a swing operation according to the contact with the obstacle accompanying the movement of the head main body part, and exhibits a function of passing the obstacle.

2) In a state where the swing head part is folded into the head main body part, the exposed part of the cleaner head generally consists of a head main body part and a connection pipe part, and the width dimension of the head main body part at that time is the connection pipe. It is substantially the same as the width dimension of the part. As a result, the cleaning of a narrower place is accelerated.

  Details of the structure and operation of the cleaner head according to the present embodiment, which can realize comfortable and easy cleaning by receiving obstacles at the place where cleaning is performed, will be described in detail below with reference to the drawings. To do.

<Structure of vacuum cleaner head>
FIG. 1 is a bird's-eye view schematically showing a configuration when the cleaner head 100 according to the present embodiment is seen from the front front in a bird's-eye view. FIG. 2 is a front view schematically showing a configuration of the front side of the cleaner head 100 when the cleaner head 100 is viewed from the direction of the arrow AR1 in FIG. In FIG. 2, most of the internal portions that are not visible from the outside are drawn with broken lines for convenience. Further, FIG. 3 is a perspective view schematically showing a configuration when the cleaner head 100 is viewed from the side.

  The vacuum cleaner head 100 generally includes a connection pipe part 10, a head body part 20, and a pair of swing head parts 30 (a first swing head part 30A on the right side and a second swing head part 30B on the left side).

A. Among these, the connection pipe part 10 is a part connected to the front-end | tip part of the hose of a cleaner (not shown), and has the hollow interior space (not shown) penetrated. The connection pipe portion 10 includes a first portion 10A made of, for example, polypropylene (an example) and a second portion 10B made of, for example, an ABS resin (an example). The second portion 10B is located on the rear end portion 20E2 side of the head main body 20 so that the connection pipe 10 can be freely rotated up and down within a certain angle range with respect to the head main body 20 as a whole. It is attached. Further, the first portion 10A of the connection pipe portion 10 is attached to the second portion 10B so as to be able to turn around the second portion 10B within an angle range of 360 °.

B. The head main body 20 is a portion extending along the longitudinal direction or the extending direction D1, and is roughly divided into a first portion 20P1 on the tip portion 20E1 side, a second portion 20P2 at the center portion, and a rear end portion 20E2. Side third portion 20P3. Among these, the 2nd part 20P2 is a part depressed more concavely than the 3rd part 20P3. In other words, the bottom surface 20BS of the third portion 20P3 protrudes from the concave bottom surface 20CBS of the second portion 20P2. As will be described later, the recessed portion of the second portion 20P2 corresponds to a portion in which a pair of swing head portions 30 folded in contact with an obstacle are accommodated. In addition, two wheels (not shown) are provided in the central portion of the bottom surface 20BS of the third portion 20P3. Similarly, two wheels 20W (hatched for convenience of illustration) having the same dimensions as the two wheels are attached to the bottom surface of the first portion 20P1. The wheels of these wheels 20W ... are made of, for example, polyacetal (an example), and the axle (not shown) is made of, for example, steel (an example). As illustrated in FIG. 1, the head main body 20 has a hollow internal space 20IS connected to the internal space (not shown) of the connection pipe portion 10. The head main body 10 is made of a resin such as ABS resin.

A characteristic point of the head main body 20 is its width dimension. That is, the width dimension W in the width direction D2 orthogonal to the longitudinal direction D1 of the head main body portion 20 is substantially equal to the width dimension of the connection pipe portion 10. Here, as an example, the width dimension W is 5 cm. In this example, as an example, a pair of swing head units 30 in a case where a pair of swing head units 30 to be described later is in a normal cleaning position, that is, the swing head unit 30 does not perform a swing operation. Or the width dimension in the width direction D2 of the cleaner head 100 is about 25 cm.

As described above, since the width dimension W of the head main body 20 is substantially equal to the width dimension of the connection pipe portion 10, the pair of swing head portions 30 are moved into the concave recess portion of the second portion 20P2 by the swing operation. When folded and housed (see FIG. 4A described later), the width dimension of the cleaner head 100 itself is the width dimension W. For this reason, the cleaner head 100 can easily enter a relatively narrow place such as a gap between furniture, and as a result, an advantage that the cleaning in the narrow place is further improved can be obtained.

C. On the other hand, each of the pair of swing head portions 30 (30A, 30B) is a portion having a characteristic structure of the cleaner head 100 and is a portion constituting the core portion of the cleaner head 100. The characteristic portion is a “swing operation” performed by each of the pair of swing head portions 30. That is, the first and second swing head portions 30A and 30B are both 1) during normal cleaning, while extending in a direction substantially perpendicular to the longitudinal direction D1 of the head body portion 20, 2) When it comes into contact with an obstacle at the time of cleaning, a swing operation is performed that freely rotates in the left-right direction AR until it is positioned in a direction substantially parallel to the longitudinal direction D1 with the position at the time of normal cleaning as a base point. The configuration of the first and second swing head units 30A and 30B for realizing the “swing operation” is arbitrary, and various configuration methods are conceivable. In the present embodiment, an example of the configuration will be described based on FIG.

In the first and second swing head portions 30A and 30B, the portion excluding the sandwich portion 31 that is hatched for convenience in the drawings is made of a resin such as ABS resin. On the other hand, the sandwich portion 31 is made of, for example, a styrene-based elastomer (an example), and is a portion that absorbs a collision caused by cleaning due to its elasticity.

In FIG. 2, the first and second swing head portions 30 </ b> A and 30 </ b> B are rotatably attached to a first portion 20 </ b> P <b> 1 on the distal end portion 20 </ b> E <b> 1 side of the head main body portion 20. It has an internal space 30IS as a hollow suction port connected to the space 20IS. That is, the first and second swing head portions 30A and 30B are portions that suck in dust, dust, and the like through the internal space 30IS.

The first portion 20P1 of the head main body 20 has a left-right symmetric substantially cylindrical protruding portion 23 having a hollow internal space protruding upward and connected to the internal space 30IS. Almost half of the side surface of the substantially cylindrical projecting portion 23 is missing, and the hollow internal space of the projecting portion 23 passes through the missing portion so that the hollow inner space 20IS in the second portion 20P2 of the head body 20 is formed. It is connected with. And between the upper surface of the protrusion part 23 arrange | positioned at right and left, and the ceiling surface 20RP, the two opposing cylindrical shafts (not shown) are provided, and each of these cylindrical shafts, For example, spring members 21 and 22 each made of stainless steel (one example) are wound and attached. In addition, the substantially cylindrical projecting portions 32 projecting from the upper surfaces on the one end sides of the first and second swing head portions 30A and 30B sandwich the both spring members 21 and 22, and surround the both spring members 21 and 22. Is fitted into the corresponding projecting portion 23 so that can be rotated. Each projecting portion 32 also has a defective portion, like the corresponding projecting portion 23, and the conduction between the hollow internal spaces is ensured through the defective portion. In other words, each protruding portion 32 rotates around the side surface of the protruding portion 23 with the central axis of the corresponding protruding portion 23 as a rotation axis.

The swing operation of the first and second swing head portions 30A and 30B using the contraction and return of the spring members 21 and 22 is as follows. Now, when the first and second swing head portions 30A and 30B are moved vertically downward with respect to the paper surface of FIG. 2, the protruding portions 32 of the swing head portions 30A and 30B are moved according to the movement. The spring member 22 is contracted while contacting the protruding end of the corresponding spring member 22 and maintaining the contact state. Then, when the movement of the first and second swing head portions 30A and 30B is stopped, the spring member 22 in the contracted state is pushed back to the original position by the reaction to be extended. By this pushing back, the first and second swing head portions 30A and 30B return to the original normal positions. On the other hand, when the first and second swing head portions 30A and 30B are moved vertically upward with respect to the paper surface of FIG. 2, the projecting portions 32 of the swing head portions 30A and 30B correspond to the movement. The spring member 21 is contracted while contacting the protruding end portion of the corresponding spring member 21 and maintaining the contact state. Then, when the movement of the first and second swing head portions 30A and 30B is stopped, the spring member 21 in the contracted state is pushed back to the original position by the reaction to be extended. By this pushing back, the first and second swing head portions 30A and 30B return to the original normal positions.

<Operation of vacuum cleaner head>
Below, operation | movement and the advantage of the cleaner head 100 using swing operation | movement of said 1st and 2nd swing head part 30A, 30B are described, referring FIG. Here, FIG. 4 is a diagram schematically showing the operation and advantages of the pair of swing head portions 30 of the cleaner head 100. In FIG. 4, reference symbol OB indicates an obstacle such as a leg of an opposing chair or opposite chair.

First, FIG. 4A shows a case where the cleaner head 100 is moved forward when the place in front of the obstacle OB facing the cleaner head 100 or the place of the gap between the obstacles OB is cleaned. The operation | movement of a pair of swing head part 30 at the time of moving to direction AR2 is shown. In accordance with the movement of the cleaner head 10, the first and second swing head portions 30 </ b> A and 30 </ b> B are substantially in the longitudinal direction D <b> 1 on the side closer to the head main body portion 20 (inside) while abutting against the obstacle OB. Until it is positioned in the parallel direction, it gradually rotates in the clockwise and counterclockwise directions A1 and A2 from the arrangement position at the time of normal cleaning and swings. As a result, when the first and second swing head portions 30A and 30B reach a position on the head main body portion 20 side that is substantially parallel to the longitudinal direction D1, the first and second swing head portions 30A and 30B reach the position that is substantially parallel to the longitudinal direction D1. The swing head portions 30A and 30B are folded and housed in the concave recess portion of the second portion 20P2 of the head main body portion 20. In this state, the width dimension of the cleaner head 100 is equivalent to the width dimension W of the head body 20. By this swing operation, the cleaner head 100 passes through the obstacle OB as it is, and easily reaches a location in front of the obstacle OB, or easily enters a gap between the obstacles OB. In this way, the first and second swing head portions 30A and 30B are swept away by the swinging operation according to the forward movement of the cleaner head 20, and the cleaner head 100 Regardless of the presence of the obstacle OB, it passes through the obstacles OB as it is, or enters the gap between the obstacles OB.

When the cleaner head 100 passes between the obstacles OB, or when the cleaner head 100 comes out of the gap between the obstacles OB, the first and second swing head portions 30A and 30B immediately swing. By the operation, it rotates counterclockwise and clockwise, and returns from the folded state in the concave recess portion of the second portion 20P2 to the arrangement position at the time of normal cleaning. In this case, the first and second swing head units 30A and 30B may be configured to remove dust / dust etc. in a front location that has passed through between the obstacles OB, or dust / dust in a gap between the obstacles OB that have entered. Dust and the like are sucked from the internal space 30IS as the suction port portion, and the place is cleaned.

  Next, FIG.4 (b) shows the state in the case of moving the cleaner head 100 which passed through between the obstructions OB and cleaned the front place to the back direction AR3 toward between the obstructions OB. Yes. In this case, according to the rearward movement of the cleaner head 100, the first and second swing head portions 30A and 30B are in contact with the obstacle OB and are closer to the front side (outside) of the head main body portion 20, respectively. ) And gradually swing in the counterclockwise and clockwise directions A3 and A4 from the arrangement position during normal cleaning until it is positioned in a direction substantially parallel to the longitudinal direction D1. As a result, the first and second swing head portions 30A, 30B are both folded and reached to a position on the front side of the head main body portion 20 that is substantially parallel to the longitudinal direction D1. The width dimension of the cleaner head 100 at this time is also substantially equal to the width dimension W of the head main body 20. Therefore, the cleaner head 100 passes through the obstacle OB without difficulty while moving along the rearward direction AR3. At that time, there is no need to move the obstacle OB or remove the obstacle OB. Then, as soon as the cleaner head 100 passes between the obstacles OB, the first and second swing head portions 30A, 30B are rotated clockwise and counterclockwise by the swing operation, Return to the position for normal cleaning.

By the swing operation performed by the pair of swing head portions 30 described above, the cleaner removes the cleaner head from the cleaner one by one without moving any obstacles such as chair legs or furniture at the time of cleaning. Without placing stress on the front of the obstacles facing each other (eg under the table) or in the narrow gap between the obstacles (eg furniture gaps) It can be cleaned comfortably. In addition, when the pair of swing head portions 30 are folded, the width dimension W of the head main body portion 20 is equivalent to the width dimension (eg, about 5 cm) of the connection pipe portion 10, and therefore, a relatively narrow place. The cleaning will be further improved.

(Modification)
In the first embodiment, the swing head portion is composed of a pair of (two) swing head portions 30A and 30B. However, the present invention is not limited to this, and the swing head portion is composed of at least one portion. It only has to be configured. Even in that case, the above-described actions and effects can be obtained in the same manner.
