Reference numeral 13 indicates rear wheels provided on both sides of the lower rear end of the cleaner body 4, and reference numeral 14 indicates caster rollers provided at the center of the lower surface of the dust suction chamber 1.

Problems to be Solved by the Invention The battery-powered vacuum cleaner described above has a problem in that the overall length is longer than the width between the running rollers, and although it is small, it is difficult to turn around and is difficult to use.

The present invention solves the above-mentioned conventional problems, and is a floor movable type that can effectively shorten the overall length, enable small turns even when using a large-capacity storage battery, and is easy to use by making smooth small turns. The purpose is to provide a vacuum cleaner.

Means for Solving the Problems In order to achieve the above object, the present invention includes a fan motor disposed below a dust suction chamber, and a storage battery disposed behind the fan motor.

Furthermore, the present invention is a storage battery in which a plurality of cells are arranged in the left-right direction of the vacuum cleaner body and integrated, and each cell is arranged so that the width direction of each cell is in the front-rear direction of the vacuum cleaner body.

Further, in the present invention, the fan motor and the storage battery are disposed approximately in the center of the cleaner body in the left-right direction.

In general, the present invention has two caster rollers disposed on the left and right sides of the fan motor, in front of the center of gravity of the fan motor.

Function: With the above structure, the overall length of the vacuum cleaner can be made approximately the same as the size of the dust suction chamber, and the overall length can be shortened to improve maneuverability. Furthermore, large-capacity storage batteries can be stored efficiently without increasing the overall length. Furthermore, it evens out the rotational force of the traveling rollers and enables smooth operation. Furthermore, it ensures stability against running and falling, and can shorten the overall length.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

First, the overall structure of the vacuum cleaner will be explained based on FIGS. 1 to 3. 20 has an opening 21 at the top, a connection port 22 at the bottom, and a dust suction chamber 24 for storing a paper bag 23, which is integrally made of synthetic resin. This is the formed vacuum cleaner body (hereinafter referred to as the main body). A gasket 26 is inserted into a groove formed in the outer periphery of the upper end of the dust suction chamber 24, and the paper bag 23 is housed inside the dust suction chamber 24 with its mouth core inserted into the holder 26. 2
Reference numeral 7 designates a lid body which covers the opening 21 and is provided with a hose insertion b 028, which is rotatably supported by a rotating shaft 29 and is detachably held by a buckle 3o. A rotatably supported handle 31 is attached to the lid body 27, and a hose 32 is connected to a connecting pipe 33.
It is inserted into the insertion port 28. 34 is a bottom plate of the main body 20 having caster rollers 36 and a rear wheel 36;
A 77-unit collector 39 is clamped and fixed in the vertical direction between the main body 20 and the connecting port 22 on the lower side of the dust suction chamber 24 via support rubbers a7 and 38. On the rear side of the fan motor 39 and in front of the rear wheel axle, a lead-sealed storage battery 40 is installed, which will be described later, in which a plurality of cells are arranged in the left-right direction of the main body and are integrated. (in this embodiment, it is inclined diagonally in consideration of ease of attachment and detachment), and is held by rib bodies 41 and 42. 43 is an opening for attaching and removing the storage battery 400 formed on the rear surface of the main body 2o, and 44 is an opening/closing lid rotatably supported.

46 is a bumper made of elastic rubber material.

Further, as shown in FIG. 2, the fan motor 39 and the storage battery 4o are arranged symmetrically at the center in the left-right direction of the main body, and two caster rollers 35 are provided on the left and right sides in front of the center of gravity of the fan motor 39. Further, as shown in FIG. 3, in this embodiment, the total length of the main body is determined approximately by the size of the dust suction chamber 24, and the widthwise dimension W and the total length are approximately equal, W x L.

Next, the structure of the lead-sealed storage battery in this example will be explained based on FIG. 4. In the same figure, 46 is the mu BS
Case 47 is made of synthetic resin such as Case 46.
The lid is glued and fixed to the The space sealed by the lid 47 in the case 4e is filled with an electrolytic solution made of dilute sulfuric acid), and Pb02 (rII lead oxide) is added to the electrolytic solution.
;b Negative electrode plates 49 made of positive FM plates aa and Pb(ffi) are alternately arranged, and separators 50 are provided to isolate each positive electrode plate 48 and negative electrode plate 490. 51
62 is a connection terminal for electrically connecting the positive electrode plate 48 and the negative electrode plate 49 in series between adjacent cells, and 62 is an external terminal.

The operation of this embodiment will be explained in the above configuration.

First, the fan motor 39 is installed below the dust suction chamber 24, and the storage battery 40 is placed behind it, which lowers the center of gravity and provides stability against running and falling. The overall length is significantly shorter than a configuration in which the fan motor is placed at the rear of the room and the storage battery is placed behind it.
Since the size can be made equal to the size of the dust suction chamber 24, the overall length can be shortened compared to the width dimension, and the main body can be configured into a shape that allows easy turning. Furthermore, the lead-sealed storage battery shown in Figure 4 is a storage battery that can easily obtain high voltage;
In this embodiment, 12 cells are connected in series and integrated to obtain an output of 3oow and a voltage of 24V. Therefore, the dimension T in the cell arrangement direction is approximately 1801n, which is the longest. In addition, in order to have a battery capacity that can continuously provide an output of 300W for about 16 minutes, the length E of each cell is 1155.
m, and the width is 46 layers. At this time, the inside of the lid 47 does not contribute to the battery capacity and is determined by the surface area of the electrode plate.
For the same area, a rectangular shape has better volumetric efficiency than a square shape. In this example, the longest direction (cell arrangement direction) is set in the left-right direction of the main body, and the cell is made thinner so that the shorter direction of the cell is arranged in the front-back direction of the main body, so even though a large capacity storage battery is used, the main body The overall length can be made shorter than the width dimension, allowing for efficient installation. Furthermore, since the motor 39 and the storage battery 4o are arranged symmetrically at the center of the main body in the left-right direction, the load applied to the rear wheels 36 is equalized and the resistance during rotation is also equal, so the load is reduced when rotating in both left and right directions. It makes no difference and can be operated smoothly.

Since two caster rollers 35 are arranged on the left and right sides in front of the center of gravity of the fan motor 39, stability is increased and the caster rollers 35 are arranged in two places on the left and right sides in front of the center of gravity of the fan motor 39. The space next to the motor 39 can be effectively utilized and the overall length can be shortened.

Effects of the Invention As described above, according to the present invention, it is possible to construct a main body shape that has a shorter overall length than its width while ensuring stability against running and falling, and provides a storage battery that is easy to turn and easy to use. You can get a type vacuum cleaner.

Further, according to the present invention, a high-capacity storage battery can be mounted without increasing the overall length, so a storage battery-type vacuum cleaner with strong suction power and good turning ability can be obtained.

Further, according to the present invention, the operational feeling during left and right rotation can be improved.
