[Industrial applications]

 The present invention relates to a vacuum cleaner.

[0002]

[Prior Art]

 A conventional vacuum cleaner includes a cylindrical main body formed of a metal plate, a front lid that covers the front opening of the main body, and a rear lid that covers the rear opening of the main body. is there. Here, a suction hose fitting inlet is formed in the front lid, and as the rear lid, the electric cord is stored so that it can be pulled out and rolled in, and the cord reel that winds up the pulled out electric cord is built in. There are some that use the reel case.

On the other hand, a partition plate (motor base) divides the inside of the main body into a dust collecting space on the front opening side of the main body and a blower space on the rear opening side. A bag-shaped dust collecting filter is arranged in this dust collecting space, while an electric blower (hereinafter referred to as a blower) consisting of a motor and a blower is arranged in the blower space with the motor base attached. In this blower, air and dust are sucked from the front opening through the suction hose by the rotation of the motor, and are collected by the dust collecting filter.

[0004]

[Problems to be solved by the device]

 However, in such a conventional electric vacuum cleaner, it is necessary to fix the motor to the main body in order to prevent the motor itself from rotating due to a reaction force at the time of starting the motor.

However, since the main body is integrally formed by press-molding a metal plate, in order to fix the motor to the main body at the time of assembly, first, a mounting portion for fixing the motor is welded to the main body. Therefore, the motor must be fixed to the mounting portion with screws or the like, and the workability during assembly is poor.

Further, when the electric vacuum cleaner is used, the dust collecting filter comes into close contact with the inner surface of the body due to the pressure of the sucked air. Therefore, the air containing the dust sucked from the suction hose is collected by the dust collecting filter. There is also a problem that dust and the like pass through the bottom portion of the filter and are concentrated on the bottom portion, which reduces the dust efficiency of the dust collecting filter.

An object of the present invention is to provide an electric vacuum cleaner capable of improving workability during assembly and efficiently collecting dust and the like.

【Example】

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

FIG. 1 is a schematic side sectional view showing a structure of an electric vacuum cleaner according to an embodiment of the present invention, and FIG. 2 is a rear longitudinal sectional view thereof. In FIGS. 1 and 2, reference numeral 1 is a main body formed of a heat-resistant synthetic resin such as polypropylene in a cylindrical shape, and a front opening 1a which is an opening at one end of the main body 1 is fitted with a suction hose (not shown). The front cover 2 is provided with a fitting opening 3, and the rear opening 1b, which is the other end opening, is covered with the reel case 4. The inner diameter of the main body 1 gradually increases from the front opening 1a to the rear opening 1b due to the punching taper formed during the die cutting during molding of the main body.

In order to lock the motor base 5 at the upper part of the inner surface of the main body 1, a motor base locking portion 6 integrally formed with the main body 1 corresponding to the dust collecting space 1c extends. At the center of the upper surface of the motor base engaging portion 6, as shown in FIG. 2, there are upper motor detent ribs 6a which are partition plate regulating ribs, and both sides of the upper motor detent rib 6a. The upper dust collecting filter holding ribs 6 b and 6 c, which are filter holding ribs, extend on the motor base locking portion 6.

The upper motor detent rib 6a engages with a later-described motor detent V-shaped groove formed in the motor base 5 to prevent the motor base 5 from reacting when the motor 7 is started. This is to prevent rotation due to force.

Further, the upper dust collecting filter holding ribs 6b and 6c are arranged so that the dust collecting filter 8 attached to the dust collecting space 1c together with the upper motor rotation-preventing rib 6a prevents the air sucked in when the cleaner is used. This is to prevent the pressure from sticking to the inner surface of the main body 1. The upper motor rotation preventing ribs and the upper dust collecting filter holding ribs 6b and 6c also serve to lock the motor base 5 together with the motor base locking portion 6.

Further, at the lower part of the inner surface of the main body 1, a lower motor rotation-preventing rib 9a and a lower dust collection rib 6a which serve the same role as the upper motor rotation-prevention rib 6a and the upper dust collecting filter-holding ribs 6b and 6c. Filter holding ribs 9b and 9c extend so as to face each other.

On the other hand, as shown in FIG. 1, a motor support rib 10 is provided on a reel support plate 9 that is attached to the front side of the reel case 3 and supports a cord reel (not shown). 7 is attached to the reel support plate 9 in a state in which the motor support rubber 12 attached to the bottom is fitted into the motor support rib 10.

Here, as shown in FIG. 3, the motor support rib 10 is provided with, for example, two protrusions 12 a of a motor support rubber 12 provided in opposite directions, so that the motor 10 is mounted on the reel support plate. This is to prevent the motor 7 from rotating due to a reaction force by engaging with the motor 9.

A blower 11a at the front of the blower 11 connected to the motor 7 is provided with a cylindrical motor cushion 13 formed of an elastic material having a large frictional resistance such as rubber. Here, the diameter of the motor cushion 13 is formed to be smaller than the diameter of the blower portion 11a, whereby the motor cushion 13 is pressed against the outer peripheral surface of the blower portion 11a and the frictional resistance thereof causes the outer peripheral surface of the blower portion 11a. It is designed to be fixed to the blower 11 without sliding.

The blower 11 around which the motor cushion 13 is provided is formed into a cylindrical shape as shown in FIG. 1, and the motor base 5 having the blower intake filter 14 attached to the front opening 5a thereof. Is fitted in the rear opening 5b. In this state, the blower 11 does not normally slide on the inner peripheral surface of the motor base 5 due to the frictional resistance of the motor cushion 13.

On the other hand, in the motor base 5, as shown in FIG. 3, two V-shaped grooves 15 for preventing the motor from rotating are formed in the front end portion of the outer peripheral surface in opposite directions. It is attached to the main body 1 in a state of abutting against the motor base locking portion 6 in a state of being locked to the driving rib 6a and the lower motor rotation stopping rib 9a. The V-shaped groove 15 serves to position the motor base 5 and prevent the motor base 5 from rotating due to the reaction force of the motor 7 at the time of starting.

When the motor base 5 is pushed forward to lock the motor base 5, the positions of the V-shaped groove 15 and the upper motor detent rib 6a and the lower motor detent rib 9a are displaced. When the motor base 5 is present, the motor base 5 is advanced due to the inclination of the V-shaped groove 15 against the frictional resistance of the motor cushion 13 so as to come into contact with the motor base locking portion 6 while rotating.

As a result, the blower 11 (motor 7) is sandwiched by the motor base 5 via the reel support plate 9 and the blower portion 11a so as not to rotate in two front and rear directions.

When the motor base 5 is fitted on the inner surface of the main body 1, the rear end portion of the outer peripheral surface of the motor base 5 is pressed against the inner surface of the main body 1 so that the inner surface of the main body 1 and the motor base 5 are hermetically sealed. An airtight holding fin 16 having elasticity for holding is provided. As a result, when the motor base 5 is fitted into the main body 1, the fin 16 for airtightness keeps contact with the inner surface of the main body 1 to maintain airtightness between the dust collecting space 1c and the blower space 1d.

In FIG. 1, 18a is a front caster, 18b is a rear caster, 19 is a hook for opening the front lid 2, and in FIG. 3, 20 is a wiring cord and 21 is a power plug. is there.

Next, the assembly of the electric vacuum cleaner thus configured will be described.

First, the main body 1 is formed of a heat-resistant synthetic resin into a cylindrical shape, and the front lid 2 is rotatably attached. Next, the fan 11 is placed on the reel case 4 while the motor 7 is stopped by inserting the motor supporting rubber 12 at the bottom of the motor 7 into the motor supporting rib 10 of the reel supporting plate 9.

Then, a motor cushion 13 is provided around the blower section 11 a of the blower 11, and then the blower 11 is fitted into the rear opening 5 b of the motor base 5 so that the motor 7 is driven by the reel support plate 9 and the motor base 5. Hold it so that it will not rotate.

Then, as shown in FIG. 4, the reel case 4 on which the motor 7 is mounted so as not to rotate is covered with the main body 1 by utilizing the removal taper. At this time, the V-shaped groove 15 of the motor base 5 is engaged with the upper motor detent rib 6a and the lower motor detent rib 9a of the main body 1. Here, when the V-shaped groove 15 and the upper motor detent rib 6a and the lower motor detent rib 9a are misaligned, the motor base 5 is rotated by the inclination of the V-shaped groove 15 so that the motor base 5 rotates. Move forward so as to come into contact with the base locking portion 6.

This makes it possible to prevent the motor base 5 from rotating due to the reaction force of the motor 7 when the motor 7 is started. Further, when the motor base 5 enters the main body 1, the fin 16 for keeping the airtightness of the motor base 5 gradually comes into contact with the inner surface of the main body 1 due to the removal taper of the main body 1, and the dust collecting space 1c and the blower space. Airtightness with 1d will be secured.

In this way, after the reel case 4 on which the motor 7 and the motor base 5 are mounted is attached to the main body 1, the front cover 2 is opened and the dust collecting filter 8 can be attached to the dust collecting space 1c. At this time, the dust collecting filter 8 includes the upper motor rotation preventing rib 6a, the upper dust collecting filter holding ribs 6b and 6c, the lower motor rotating prevention rib 9a, and the lower dust collecting filter holding ribs 9b and 9c. Thus, it is held so as not to come into close contact with the inner surface of the main body 1.

As a result, when the vacuum cleaner is used, it is possible to prevent the dust collecting filter 8 from coming into close contact with the inner surface of the main body 1 due to the pressure of the sucked air, and the air containing dust or the like can be prevented. Now, not only the bottom but also the side can pass, and dust can be collected not only on the bottom but also on the side.

As described above, the blower 11 (motor 7) is not rotated in the two front-back directions by the reel support plate 9 and the motor base 5 without welding or the like to the main body 1 made of synthetic resin. Can be pinched. Moreover, the pressure of the air sucked by the dust collecting filter 8 when the vacuum cleaner is used is increased by the upper motor rotation preventing rib 6a and the upper dust collecting filter holding ribs 6b and 6c which are integrally formed in the main body 1. This makes it possible to prevent it from coming into close contact with the inner surface of the main body 1.

[0034]

[Effect of the device]

 As described above, according to the present invention, the electric blower includes the partition plate that is mounted on the cylindrical body made of synthetic resin to form the dust collecting space and the blower space, and the rear lid that covers the opening at the other end of the main body. Can be held. Moreover, the rotation of the partition plate can be restricted by the plurality of partition plate regulating ribs integrally formed on the main body corresponding to the dust collecting space. As a result, welding or the like for fixing the motor is not necessary, so that the assembling workability can be improved and the production cost can be reduced.

In addition, the plurality of partition plate regulating ribs and filter holding ribs can prevent the dust collecting filter from coming into close contact with the inner surface of the main body due to the pressure of the air sucked into the dust collecting filter when the electric vacuum cleaner is used. Therefore, dust and the like can be collected efficiently.
