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

Reference numeral 1 denotes a cleaner body, which forms a dust collection chamber 3 having a front opening for detachably storing a dust collection bag 2 below, and
An electric motor storage chamber (both not shown) containing an electric blower is formed above. A front opening of the dust collecting chamber 3 is covered with a lid 4 so as to be freely opened and closed.

Reference numeral 5 denotes a suction tube portion formed at the lower portion of the cleaner main body 1 so as to communicate with the dust collection chamber 3, and a rotary pipe 11 of a suction tool body 8 described later is inserted into the suction tube portion 5 and connected thereto. It is supposed to be.

Reference numeral 6 denotes a handle disposed on the upper portion of the cleaner main body 1. The handle 6 is foldably attached to the cleaner main body 1, and an operation switch 7 is disposed on the handle 6.

Numeral 8 denotes a suction tool main body attached to a lower portion of the cleaner main body 1, and upper and lower cases 9, 10,
A rotation tube 11 is rotatably supported in the vertical direction on the rotation tube 10.

An engaging projection 12 is provided on a part of the outer circumference of the rotating pipe 11.
Are arranged in a state of being urged in the outer peripheral direction, and when the rotary pipe 11 is inserted into the suction cylinder section 5 of the cleaner body 1, the rotation pipe 11 engages with the engagement hole 13 formed in the suction cylinder section 5. In addition, the rotating pipe 11 and the cleaner main body 1 are connected, and the rotating pipe 11 and the cleaner main body 1 are prevented from rotating.

Numeral 14 designates a hollow rotary shaft formed in the rotary tube 11. The rotary shaft 11 is sandwiched between the upper and lower cases 9, 10 so that the rotary tube 11 is attached to the suction tool main body 8. The cleaner body 1 is vertically rotatable with respect to the suction tool body 8 by inserting the rotating pipe 11 into the suction tube 5 of the cleaner body 1. It is arranged freely, that is, it can be turned upside down. The downward rotation range of the cleaner main body 1 is regulated so that the end of the cleaner main body 1 or the handle 6 does not come into contact with the floor surface.

One of the rotating shafts 14 of the rotating pipe 11 is closed by a rib 15 erected on the lower case 10, and the other is connected to a bypass passage 16 (described later) of the suction tool main body 8. Let me.

Reference numeral 16 denotes a bypass passage formed on one side of the suction tool main body 8, one end of which is connected to the rotation shaft 14 of the rotation pipe 11, and the other end formed on the upper surface of the suction tool main body 8. The hose 18 has a substantially L-shaped cross section communicating with a hose connection port 17 to which a hose 18 is connected (both will be described later).

Reference numeral 17 denotes a cylindrical hose connection port integrally formed on one side of the upper case 9 of the suction tool main body 8, and a rotation fulcrum of the cleaner main body 1 with respect to the suction tool main body 8, that is, of the rotation pipe 11. The hose is formed so as to be substantially perpendicular to the suction tool main body 8 at a position forward of the rotation shaft 14, and one end of a flexible hose 18 is detachably connected to the hose connection port 17.

The other end of the hose 18 is removably attached to an attachment portion 19 formed on the upper side surface of the cleaner main body 1. During operation of the electric blower, the suction tool main body 8 and the hose are connected.
Since the inside of the hose 18 has a negative pressure, the other end of the hose 18 sticks to the mounting portion 19 so that the inflow of outside air from the other end of the hose 18 is prevented, and the gaps between shelves and furniture are cleaned. In this case, as shown in FIG. 6, the other end of the hose 18 is detached from the mounting portion 19 and used.

Reference numeral 20 denotes auxiliary wheels disposed on both front sides of the suction tool main body 8, and reference numerals 21 denote wheels disposed on both rear sides of the suction tool main body 8. The auxiliary wheels 20 and the wheels 21 are grounded on the floor. In this state, a gap is secured between the bottom surface of the suction tool main body 8 and the surface to be cleaned.

According to the above configuration, when cleaning, the cleaner 6 is used with the handle 6 being held down with respect to the suction tool main body 8 while the handle 6 is held down. Since a clearance between the bottom surface of the tool body 8 and the surface to be cleaned is secured, and the inflow of outside air from the other end of the hose 18 is prevented, the air sucked from the suction opening of the suction tool body 8 is circulated. It is guided to the cleaner main body 1 via the moving tube 11.

When cleaning the gap between shelves and furniture, the other end of the hose 18 is removed from the mounting portion.
The air sucked from the other end of the
Flows into the cleaner main body 1 through the rotary shaft 14 of FIG.

When cleaning the carpet, the wheels 21 and the auxiliary wheels
Since 20 sinks into the fur of the carpet, the gap between the bottom surface of the suction tool body 8 and the carpet becomes narrow, and when the negative pressure in the suction tool body 8 and the hose 18 increases, the force of contracting the hose 18 is applied. Thus, a force for lifting the front of the suction tool main body 8 is applied.

During cleaning, as shown in FIG.
Is brought down with respect to the suction tool body 8, but the hose 18
The hose connecting portion 17 to which one end of the hose is connected rises in the vertical direction on the upper surface of the suction tool body 8 ahead of the rotation shaft 14 of the rotation pipe 11, so that when the hose 18 tries to contract, the suction tool body A force is applied to the upper portion 8 of the rotating tube 11 as a fulcrum with the rotating shaft 14 as a fulcrum, so that the suction device main body 8 does not stick to the cleaning surface and the operating force of the suction device main body 8 is reduced.

If the front of the suction tool main body 8 rises too much, the inflow of air increases, the negative pressure in the hose decreases, and the front of the suction tool main body 8 lowers.

Therefore, by repeating the above operation, the suction force can be made constant, and the suction force of the suction tool body 8 can be prevented from sticking to the floor surface, thereby preventing an increase in the operating force during cleaning. 8 can be improved to improve the usability.

In the above embodiment, the hose connection portion 17
In front of the rotary shaft 14 of the rotary tube 11 and the suction tool body 8
When the suction tool main body 8 and the inside of the hose 18 become extremely negative pressure, that is, when the suction tool main body 8 sticks to the cleaning surface while cleaning the carpet or the like, the hose 18 Although the front of the suction tool main body 8 is most easily turned upward along with the contraction, if the hose connection portion 17 is located forward of the rotation shaft 11 of the rotation pipe 11, the suction tool main body 8 can be rotated. The same effect can be obtained even if the hose connecting portion 17 is formed substantially perpendicular to the suction tool main body 8 if the hose connecting portion 17 is formed substantially perpendicular to the suction tool main body 8. Axis 14
Even if it is formed in the vicinity, the same operation and effect can be obtained.

Although the hose connecting portion 17 is formed substantially perpendicular to the suction tool main body 8, the hose connecting portion 17 is in a state where the cleaner main body 1 is tilted with respect to the suction tool main body 8, that is, during cleaning. The angle may be larger than the angle between the cleaner body 1 and the floor.

In other words, even when the suction tool body 8 is formed at an angle of 90 ° or less with respect to the floor surface in a state where the cleaner body 1 is folded down, the suction tool body 8 is formed.
If the negative pressure in the hose 18 increases, the hose
A force for rotating the suction tool main body 8 upward due to the contraction of the suction tool main body 8 is applied, so that suction of the suction tool main body 8 can be prevented and mobility can be improved.

Conversely, even when the suction tool body 8 is formed at an angle of 90 ° or more with respect to the suction tool body 8, if the vacuum inside the suction tool body 8 and the hose 18 increases while the cleaner body 1 is in the down position, the hose A force for rotating the suction tool body 8 upward due to contraction of the suction tool body 8 is applied to prevent suction of the suction tool body 8 and improve mobility, but the hose holding the other end to the cleaner body 1 Since the connection near the end of the hose connecting portion 17 side of the hose 18 is sharply curved, a problem such as breakage due to a force applied to the vicinity of the end portion of the hose 18 on the hose connecting portion 17 side can be considered.

Accordingly, when the hose connecting portion 17 is formed substantially perpendicular to the suction tool main body 8 as in the present embodiment, the suction tool main body 8 is sucked to the floor without applying a load to the hose 18. In the state, the force for rotating the suction tool main body 8 upward is most easily applied.

When the hose 18 is formed substantially perpendicular to the suction tool main body 8, in the state where the cleaner main body 1 is placed for the longest time, that is, in the storage state (the state where the cleaner main body 1 is standing up), Since the hose 18 is in a natural state, the hose 1
8 can have a very long life.

Further, in the above-described embodiment, the mounting portion 19 for holding the other end of the hose 18 is formed on the upper side of the cleaner body 1, but the inside of the hose 18 and the suction tool body are If a pressure is applied in the direction in which the suction tool main body 8 rotates upward with the contraction of the hose 18 when the inside of the vacuum chamber 8 becomes a negative pressure, the suction tool main body 8 may be formed on the rear surface or the front surface of the cleaner main body 1. Good.

[0034]

According to the first aspect of the present invention, the connection port is
Because the suction tool body is formed in front of the suction tool main body from the rotation fulcrum of the vacuum cleaner body, if the gap between the suction tool body and the cleaning surface becomes narrower while cleaning a carpet, the suction tool body is shrunk as the hose contracts. Since the force is applied in the direction in which the front part rotates upward, the suction tool main body is prevented from sticking to the cleaning surface, so that the mobility of the suction tool main body can be improved and the usability can be improved.

According to the second aspect of the present invention, the connection port is formed at an angle larger than the angle with respect to the floor surface when the cleaner body is in use. When the gap becomes narrow, a force is applied in the direction in which the front of the suction tool body rotates upward with the contraction of the hose, so that the suction tool body is prevented from sticking to the cleaning surface to prevent suction. The mobility of the main body can be improved and the usability can be improved.

Further, according to the third aspect of the present invention, since the connection port is formed substantially perpendicular to the suction tool main body, the gap between the suction tool main body and the cleaning surface becomes narrower while cleaning the carpet or the like. In addition, a force is applied in the direction in which the front of the suction tool body rotates upward as the hose contracts, thereby preventing the suction tool body from sticking to the cleaning surface and improving the mobility of the suction tool body. Usability can be improved.

By forming the connection port substantially perpendicular to the suction tool main body, a load is hardly applied to the vicinity of the connection portion of the hose to the connection port during cleaning, and the housing state of the cleaner main body (when the cleaner main body is closed). In the upright state), the hose is in a natural state, and the life of the hose can be extended.

According to the fourth aspect of the present invention, the connection port is formed substantially perpendicular to the suction tool main body in front of the suction tool main body from the rotation fulcrum of the cleaner main body. When the gap between the suction tool body and the cleaning surface becomes narrow,
The force is most easily applied in the direction in which the front of the suction tool body rotates upward as the hose contracts, preventing the suction tool body from sticking to the cleaning surface and improving the mobility of the suction tool body. Performance can be improved.
