  However, the above-described conventional technique is not sufficient in that it cleanly cleans a low place such as under a bed. That is, in the conventional upright type vacuum cleaner, when the main body of the vacuum cleaner is in contact with the floor surface, the pair of wheels of the suction port body and the one wheel on the back of the vacuum cleaner body are in contact with the floor surface. Since the vacuum cleaner body is supported at three points by three wheels, it is easy to move the vacuum cleaner body in the front-rear direction, but it is difficult to move it diagonally or even in the lateral direction There is. For this reason, in the conventional upright type vacuum cleaner, it is necessary to move it sideways little by little while moving the main body of the vacuum cleaner in the front-rear direction, and it is impossible to clean well.

  Also, if the main body of the vacuum cleaner cannot be easily moved diagonally or laterally, it will be easier to store the vacuum cleaner under the bed if it is placed under the bed. Inevitably, it takes time to store.

  The subject of this invention is providing the upright type | mold vacuum cleaner which can clean easily a low height place and can be easily accommodated in a low height place.

  In order to solve the above-mentioned problems, a feature of the present invention is that a planar friction reducing member is provided at a position in contact with the floor surface in the back surface of the cleaner body. That is, the present invention comprises a vacuum cleaner body incorporating an electric blower, a suction port body provided at a lower portion of the vacuum cleaner body and having a running wheel, and a handle portion provided at an upper portion of the vacuum cleaner body. An upright type electric vacuum cleaner in which the main body of the vacuum cleaner is tiltable with respect to the suction port body, and when the main body of the vacuum cleaner is tilted and slid on the floor surface, the vacuum cleaner A surface friction reducing member for reducing friction with the floor surface is provided at a position in contact with the floor surface on the back surface of the main body.

  When the vacuum cleaner main body is tilted greatly when cleaning a low place such as under a bed, a part of the back of the vacuum cleaner main body comes into contact with the floor surface. Since the surface friction reduction member is provided at the location, it is possible to reduce the frictional force between the floor surface and the vacuum cleaner body easily in both the diagonal and horizontal directions as well as the front and rear direction. Can be moved. As a result, it is possible to clean a low place such as under the bed.

  In addition, the vacuum cleaner body can be arbitrarily moved in the front-rear direction, diagonal direction, and lateral direction, so it is easy to push the vacuum cleaner body under the bed while storing the vacuum cleaner while avoiding luggage under the bed. And can be stored easily.

  According to the present invention, since the surface friction reducing member is provided in the rear surface of the vacuum cleaner main body at the position that comes into contact with the floor surface, it is possible to cleanly clean a low place such as under the bed. The vacuum cleaner can be easily stored in a low-priced place.

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

  FIG. 1 is an overall perspective view of an upright type vacuum cleaner according to the present invention. The upright type vacuum cleaner 1 includes a vacuum cleaner body 3 having an electric blower 2, a suction port 4 provided at a lower portion of the vacuum cleaner body 3, and a handle provided at an upper portion of the vacuum cleaner body 3. Part 5.

  A pair of wheels 6, 6 are rotatably attached to the lower surface of the suction port body 4, and the wheels 6, 6 allow the entire vacuum cleaner 1 to be moved back and forth along the floor surface to be cleaned (see FIG. 1 (in the direction of arrow A).

  The vacuum cleaner body 3 is provided so as to be tiltable in the arrow B direction with respect to the suction port body 4. That is, the connecting portion 7 between the cleaner body 3 and the suction port body 4 is attached to the suction port body 8 so as to be freely tiltable, and the cleaner body 3 can be tilted at an arbitrary angle in the arrow B direction. In addition, a dust collecting container 9 is detachably attached to the lower portion of the cleaner body 3.

  The handle part 5 can be expanded and contracted in the direction of the arrow C, and when cleaning, the user of the vacuum cleaner extends the handle part 5 to an easy-to-handle length and locks the position of the handle part 5 with the length to perform cleaning. It can be carried out.

  Reference numeral 10 denotes a cord, and a plug 11 is provided at the tip of the cord 10. Although not shown, a cord winder is provided inside the cleaner body 3, and when the upright type vacuum cleaner 1 is not used, the cord 10 is wound around the cord winder. .

  In this embodiment, a raised cloth 12 is attached as a planar friction reducing member to a corner portion on the back side of the cleaner body 3 (opposite side of the dust collecting container 9). The brushed cloth 12 has a planar shape, and is provided from the lower back surface 3A of the cleaner body 3 to the lower end surface 3B of the cleaner body 3 as shown in FIG. In addition, the back side of the cleaner body 3 forms a cylindrical surface.

  Further, in the present embodiment, a convex portion 13 projecting laterally from the cleaner main body 3 is provided integrally with the cleaner main body 3 at the rear upper and lower intermediate position of the cleaner main body 3. As shown in FIG. 3, the protruding portion 13 has a protruding tip part of a square shape, and when the cleaner body 3 is greatly tilted, that is, placed on the floor sideways, the posture of the cleaner body 3 is Can be maintained stably. In addition, you may form the convex part 13 with elastic members, such as rubber | gum. Also, an elastic member such as rubber can be attached to the tip of the convex portion 13.

  Next, the operation of the vacuum cleaner 1 having the above configuration will be described.

  First, when cleaning a low place such as under a bed, the cleaner user is in a state where the cleaner body 3 is not tilted with respect to the suction port body 4 (suction port body) as shown in FIG. 4 and the vacuum cleaner main body 3 are arranged substantially at right angles), then hold the handle portion 5 by hand and greatly tilt the entire vacuum cleaner 1 to floor 14 (the floor 14 is under the bed, etc.) The floor is connected to the floor. Then, the vacuum cleaner main body 3 is slid in the front-rear direction, the diagonal direction, or the horizontal direction on the floor surface 14 while maintaining this posture, and the underside of the bed is cleaned.

  In the present embodiment, since the raised cloth 12 is attached to the back side corner portion of the cleaner body 3, the frictional force with the floor surface 14 can be reduced. The brushed fabric 12 has a large number of fine brushed plants planted on the fabric, and when the cleaner body 3 moves and rubs against the floor surface 14, the many brushed fabrics are the same as the moving direction of the cleaner body 3 opposite. Since the direction and the contact area with the floor surface 14 can be reduced, the frictional force with the floor surface 14 can be reduced. As a result, the vacuum cleaner user can slide the electric vacuum cleaner 1 on the floor surface 14 with a light operating force, and can easily perform cleaning.

  Next, when storing under the bed or the like, as in the case of cleaning, the entire cleaner 1 is largely inclined as shown in FIG. Is slid on the floor 14 and the entire vacuum cleaner 1 is pushed under the bed or the like.

  Also in this case, since the raised cloth 12 is attached to the back side corner of the vacuum cleaner main body 3, the frictional force with the floor surface 14 is reduced, and the vacuum cleaner 1 can be moved on the floor surface 14 with a light operating force. Can be slid and stored by being pushed under the bed or the like.

  When the vacuum cleaner 1 is stored under the bed or the like, the vacuum cleaner user releases his hand from the handle portion 5. In the present embodiment, the raised cloth 12 has a surface shape, and the convex portion 13 having a part of a square shape is provided at the upper and lower intermediate positions on the back side of the cleaner body 3. The posture can be maintained stably. In this case, if an elastic member such as rubber is provided at least on the tip side of the convex portion 13, it is possible to reduce the impact on the cleaner body 3 when the cleaner user releases his hand from the handle portion 5. .

  According to the present embodiment, the brushed cloth 12 is provided at the corners on the back side of the cleaner body 3, and the convex portions 13 are provided at the upper and lower intermediate positions on the back side of the cleaner body 3. The machine 1 can be easily stored in a low place such as under the bed, and the posture of the vacuum cleaner 1 after being stored can be stably maintained.

  Instead of the raised cloth 12, a resin having a small surface roughness may be provided at the back side corner of the cleaner body 3. Further, a plurality of small protrusions along the axial direction of the cleaner body 3 may be provided on the back side corner portion of the cleaner body 3.
