2. Description of the Related Art There is known a type of portable vacuum cleaner in which the vacuum cleaner is held on a waist of a body using a belt.

[0003] By the way, the electric blower incorporated in the main body case of the electric vacuum cleaner is disposed in the equipment room immediately adjacent to the dust collection room. While the dust collection chamber is a large space in which the dust bag is installed, the electric blower is a heavy device, so when the vacuum cleaner is fixed to the body, the center of gravity of the vacuum cleaner weighs heavier. There is a tendency to be largely biased toward the side that accommodates the motor having the irregularities.

[0004]

This type of vacuum cleaner is originally portable, and its weight is designed so as not to be so troublesome, but it is often inconvenient to handle due to the bias of the center of gravity of the vacuum cleaner. Come. That is, when the vacuum cleaner is fixed to the waist of the body using a belt, the center of gravity of the vacuum cleaner is biased toward the side where the motor is housed, making it difficult to maintain a stable state on the body. For this reason, the operation is forced to be temporarily interrupted, such as correcting the position of the vacuum cleaner which is displaced from the waist, which causes a reduction in efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a waist-wound vacuum cleaner in which the center of gravity of the vacuum cleaner is prevented from being biased toward the side where the electric blower and the motor are housed, and can be stably held on the body.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a main body case having a dust collecting chamber and a built-in electric blower, a storage battery case mounted on the main body case and containing a storage battery, and a main body. A belt attached to the case and fixing the main body case to the user's waist; and the storage battery is disposed on the dust collection chamber side.

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 3, the vacuum cleaner has a main body case 1 made of a hard resin material in which an electric blower, a motor, and the like described below are housed. This body case 1
Is provided with a soft resin belt 3 held by a belt retainer 2 made of a hard resin material. The belt 3 is wrapped around the user's waist (see FIG. 4), and the vacuum cleaner is used. It can be fixed to the body.

Further, as shown in FIG. 5, in this embodiment, a dust collection chamber 5 is formed in the main body case 1 and communicates with the suction cylinder 4 facing one end of the main body case 1. A dust bag 6 for collecting dust is mounted in the dust chamber 5. In the main body case 1, an equipment room 7 is formed near the other end thereof, and an electric blower 8 having a fan driving motor 9 is housed therein.

By the way, the belt 3 passes the boss 11 of the belt fastening 2 through the belt hole 10 thereof, and
Are fitted and fixed to the boss 12 of the main body case 21. Reference numeral 13 in the drawing denotes a dust collection chamber lid made of a hard resin material that separates the inside of the dust collection chamber 5 from the outside air.

On the other hand, as shown in FIG. 1, a battery case 14 made of a hard resin material is provided below the main body case 21. In this battery case 14, as shown in FIG.
A storage battery chamber 15 is formed on the dust collection chamber 5 side of the main body case 1 with a length and a width determined according to the number of storage batteries, and the determined number of storage batteries 16 are stored therein. The plurality of storage batteries 16 are arranged in balance with the electric blower 8 accommodated in the equipment room 7 of the main body case 1.

The present embodiment has the above configuration.
Since the plurality of storage batteries 16 housed in the storage battery compartment 15 of the battery case 14 are arranged on the dust collection chamber 5 side while maintaining the weight balance with the electric blower 8, the center of gravity of the vacuum cleaner is substantially set in the horizontal direction. Can be centered. Thus, when the vacuum cleaner is fixed to the center of the body, the center of gravity coincides with the center of the body, and the vacuum cleaner can be always held in a stable state.

To balance the weight, for example, there is a method of arranging the electric blower 8 at a position close to the center of the main body case 1.
Is undesirably reduced in volume. In the present embodiment, since the storage battery 16 is arranged in the storage battery chamber 15 of the battery case 14 so as to balance the weight with the electric blower 8 housed near the other end of the main body case 1, the dust collection chamber 5 Without any influence on the volume of the battery, it is possible to secure the originally required volume.

Further, in this embodiment, since each storage battery 16 is disposed in the storage battery compartment 15 remote from the electric blower 8, for example, when the motor 9 of the electric blower 8 has heat due to long-time use. Also a long storage battery 1
6, the battery performance can be prevented from deteriorating.

As described above, according to the present embodiment, when the vacuum cleaner is fixed to the body, it is possible to prevent the vacuum cleaner from leaning toward the side housing the electric blower 8 due to the bias of the center of gravity. The vacuum cleaner can be stably held on the body.

FIGS. 6 to 9 show another embodiment of the present invention.
This will be described with reference to FIG. In FIG. 6, the electric vacuum cleaner has a main body case 21 made of a hard resin material for accommodating an electric blower and the like to be described later. On the front surface of the main body case 21, a soft resin belt 23 fixed by a belt fastening 22 made of a hard resin material and a soft resin cushion 24 described later in detail are provided.

As shown in FIG. 7, the belt 23 passes a boss 26 of the belt fastening 22 through a belt hole 25, and the boss 26
8, the cushion 24 is passed through the boss 29 of the belt fastening 22 through a through hole 28 formed in the center as shown in FIG. It is fixed so as to be sandwiched between it and the belt fastening 22. Further, a plurality of cushion through-holes 30 are formed in the belt fastening 22 so as to project hollow portions and solid portions of the cushion 24 described later outward.

As shown in FIG. 7, a dust collecting chamber 32 is formed in the main body case 21 and communicates with a suction cylinder 31 facing one end thereof. 33 are mounted. Further, an equipment room 34 is formed in the main body case 21 near the other end thereof, in which an electric blower 35 having a fan driving motor 36 is housed. Reference numeral 37 in the drawing indicates a dust collection chamber lid made of a hard resin material that is separated from outside air in the dust collection chamber 31.

9 (a), 9 (b) and 9 (c) show details of the cushion 24. FIG. The cushion 24 according to the present embodiment is composed of two hollow portions 3 having a semicircular cross section that are long in the center portion.
8. At both ends, two solid portions 39 having a semicircular cross section shorter in length than the hollow portion 38 are provided. The two hollow portions 38 at the center are formed with high flexibility and easy to fit the body. On the other hand, the two solid portions 39 at both ends have lower flexibility than the hollow portion 38 and are formed so as not to be easily deformed. Further, the two hollow portions 38 are spaced apart from each other, and at the same time, the two solid portions 39 are also arranged at intervals between each other. Each through-hole 30 (see FIG. 8) of the above-mentioned belt fastening 22 is formed in accordance with the hollow portion 38 and the solid portion 39, respectively.
As shown in FIG. 7, the distal ends of the hollow portions 38 and the solid portions 39 are configured to protrude from the belt stopper 22, respectively.

This embodiment has the above configuration.
Before use, vacuum cleaner on the back waist belt 2
2 and apply the belt 23 around the body to fix it. At this time, each part of the cushion 24 protruding from the outer surface of the belt fastening 22 applied to the waist contacts the body a as shown in FIG.
Each hollow portion 38 having high flexibility deforms (indicated by phantom lines in FIG. 8) in contact with the body a and becomes slightly flat.
On the other hand, each inflexible solid portion 39 hardly deforms even when it comes into contact with the body a, and maintains its shape as it is.

In order to fix the vacuum cleaner to the waist without a sense of incongruity, it is necessary to change the shape of the cushion 24 so that the cushion 24 can always maintain a familiar state according to the body size of each person. Each hollow part 3 to be arranged
8 is deformed following the line of the body each time. That is, when following the body a of FIG. 7 having a large body size, the hollow portion 38 is slightly deformed to fit the body a. In contrast,
When following the body b having a small body size, the hollow portion 38 is deformed more to fit the body b. in this way,
According to the present embodiment, even when the body size of each user is different, it is possible to always give the best fit without any dissatisfaction.

Although the cushion 24 of the above embodiment is fixed to the main body case 21 by using the belt fastener 22, it may be fixed by using an adhesive on the outer surface of the belt fastener 22. The hollow portion 38 of the cushion 24 does not need to have a hollow structure as long as the hollow portion 38 is flexible and can perform the same function.
