Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a hand cleaner, in which a plurality of legs are provided around a dust suction fan protruding from the bottom of a drive case.

(Prior Art) A hand cleaner for cleaning tables, etc. generally consists of a drive case that houses batteries, motors, etc., and a cap case that is detachably attached to the bottom of the drive case. Dust is sucked into the dust collection chamber of the cap case by a dust suction fan disposed at the bottom of the drive case, the cap case is separated from the drive case, and the dust inside the dust collection chamber is taken out. By the way, the fan of conventional hand cleaners was exposed by protruding from the bottom of the drive case, which has the advantage of making it easy to clean the fan and its surroundings, but when cleaning the cap case, the drive case When placed on a table, etc., the fan may hit the table surface and damage it, or the fan's rotating shaft may become eccentric due to the shock or load during placement, reducing the dust collection power of the fan. The dot was hot.

For this reason, for example, Utility Model Application No. 51-8667 and Utility Model Application No. 53-
As shown in No. 57667, a fan chamber is provided at the bottom of the drive unit case, and the fan is stored inside the fan chamber.
Also known is a fan in which the fan is covered with other members such as a fan guide or a partition plate. However, although this type of device has the advantage of solving the problems of the conventional ones mentioned above and sufficiently protecting the fan, if the fan guide and partition plate are not removed by loosening the screws, There was a problem where cleaning could not be done.

(Purpose of the invention) The present invention has been made in view of the above circumstances, and it is possible to easily clean the inside, and to clean the inside, the cap case can be removed from the drive part case. To provide a hand cleaner that does not cause damage to a fan when it is placed on a table or the like.

(Summary of the invention) In the present invention, a fan chamber is not provided in the drive unit case in which the fan is disposed, and the fan is provided in a protruding manner so as to be exposed at the bottom of the drive unit case. A plurality of legs protruding downward from the lower end of the fan are provided around the fan. With this configuration, in order to clean the inside of the hand cleaner, the fan is exposed when the cap case attached to the bottom of the drive unit case is removed, and dirt and debris attached to the fan and its surroundings can be removed. making it easy to clean. In addition, when cleaning a cap case equipped with a dust collection chamber, the drive unit case is placed on a table or the like using legs, so that the fan does not hit the table surface. This prevents damage to the fan, its rotating shaft, etc.

(Example 1) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a partially cutaway side view of the hand cleaner, and FIG. 2 is an exploded perspective view, in which 1 is a main body case, a drive part case 2 and a cap detachably attached to the bottom of the drive part case 2. It consists of Case 3. A motor 5 driven by a battery 4 is installed in the center of the drive unit case 2, and its rotation shaft 5
A dust suction fan 6 is attached to a. The drive unit case 2 does not have a fan chamber for storing the fan 6, and the fan 6 protrudes from the bottom surface of the drive unit case 2, but three leg bodies 7 are protruded at equal intervals around the fan 6. , the lower ends of these legs 7 are the fans 6
It protrudes slightly below the bottom edge of the.

The cap case 3 is attached to the drive unit case 2 so as to cover the fan 6, and an intake cylinder 8 is formed in the center of the bottom of the cap case 3. A partition plate 9 in which an intake hole 9a is formed is removably inserted into the upper part of the intake cylinder 8, and a dust collection chamber 10 is formed between the partition plate 9 and the bottom plate of the cap case 3. . Reference numeral 11 indicates a number of ventilation holes formed in the side wall of the cap case 3. Air sucked from the intake pipe 8 by the rotation of the fan 6 passes through a filter 12 and is discharged from the ventilation hole 11, and is also discharged from the cap together with the air. The dust sucked into the case 3 falls into the dust collection chamber 10 through the notch 9b of the partition plate 9 and is collected. Reference numeral 13 denotes a cushion member consisting of a brush installed in a helical pattern around the intake hole.As the cleaner is moved on the cleaning surface, this cushion member 13 sweeps away dirt toward the central intake pipe 8. Improves the cleaning effect of scraping.

In the above configuration, when cleaning the inside of the hand cleaner, remove the cap case 3 from the drive unit case 2, place the drive unit case 2 on the table using the legs 7 (see Fig. 3), and then Then, remove the partition plate 9 from the cap case 3 to open the dust collection chamber 10, and take out the garbage accumulated inside. In this way, the drive part case 2 is connected to the leg body 7.
Since the stand leg is placed on the table via the stand, the fan 6 will not be damaged by hitting the top surface of the table, and the rotating shaft 5a of the fan 6 will not become eccentric. Further, since the fan 6 is exposed at the bottom of the drive unit case 2, the fan 6 and its surroundings can be easily cleaned with a trowel.

Next, when the cleaning of the cap case 3 is completed, the partition plate 9 is attached to the cap case 3 again, and the cap case 3 is attached to the drive unit case 2, but the partition plate 9 is not attached to the cap case 3 correctly. Even if the partition plate 9 is tilted as shown by the chain line in FIG. It becomes horizontal and is correctly attached to the cap case 3.

(Embodiment 2) FIGS. 4a and 4b show another embodiment of the present invention, in which a locking step is provided at the lower end of the leg 7 protruding from the bottom surface of the drive unit case 2. A portion 7a is formed. Further, the partition plate 9 has an arc-shaped elongated hole 14a for removably locking each step portion 7a,
Three locking holes 14 are formed which are circular holes 14b connected to one end of the elongated hole 14a.

In the above configuration, the lower end of each leg 7 is connected to each circular hole 1.
4b and rotate the partition plate 9 clockwise in FIG. Ru. If the partition plate 9 is connected to the legs 7 in this way, the driving unit case 2 can be placed on a standing leg, such as on a table, etc., using each leg 7, as in the first embodiment. (See Figure b), when the drive unit case 2 is removed from the cap case, the partition plate 9 is also removed and the dust collection chamber is opened, so that the dust inside the dust collection chamber can be immediately removed, and the drive If the compartment case 2 is attached to the cap case, the partition plate 9 will also be covered by the dust collection chamber at the same time, making its handling extremely simple. Note that in this embodiment, the partition plate 9
is removably connected to the leg body 7, but may be fixed to the leg body 7 using an adhesive, for example.

(Effects of the invention) As explained above, the dust suction fan 6 of the hand cleaner according to the invention is protruded from the bottom of the drive case 2, so when the cap case 3 is removed from the drive case 2, the fan 6 is removed. The fan 6 and its surroundings can be easily cleaned. Furthermore, when cleaning the dust collection chamber 10 of the cap case 3, the drive part case 2 can be placed on a table surface or the like by means of the legs 7, so that the fan 6 and its rotating shaft will not touch the table surface. etc. will not hurt.
