Description

[Detailed Description of the Invention] The present invention relates to a small electric vacuum cleaner that can easily suction and remove dust from homes, cars, etc. by rotating blades using a motor.

In conventional small electric vacuum cleaners of this type, when air sucked in by the blades is discharged, the air is discharged from the rear of the vacuum cleaner body. However, in this case, there are problems in that the dust that is being sucked and removed is blown away, and the exhaust air is blown onto the human body, making it uncomfortable.

In addition, a vacuum cleaner with exhaust holes all around the body has been proposed, but in this case too, the exhaust air blows away dust on the floor or tatami surface that is being cleaned, reducing cleaning efficiency and making the user feel uncomfortable. This caused discomfort due to the blowing of dust.

The present invention has been devised to solve the above-mentioned conventional problems, and the present invention will be explained below based on drawings showing embodiments thereof.

In FIGS. 1 and 2, 1 is a vacuum cleaner main body, and this vacuum cleaner main body 1 is constructed by fitting and fixing a resin body consisting of two parts of almost the same shape together with screws (not shown). , and a grip portion 2 is formed in a part thereof, and a power switch 3 is further provided in front of the grip portion 2. 4 is the vacuum cleaner body 1
This chassis 4 is fitted and fixed inside.
The motor 5 is fixed to the lead 7, and a lead 7, which is in contact with a power supply battery 6 and constitutes a current supply circuit to the motor 5, is fixed to the lead 7. The power switch 3 and the motor 5 are electrically connected via a lead wire 8, and the lead 7 and the motor 5 are also electrically connected via a lead wire 9. 10 is a centrifugal blade fixed to the rotating shaft 5a of the motor 5; 11 is an air guide for efficiently exhausting the air generated by the rotation of the blade 10;
1 has a spirally curved shape and is fitted and fixed to the vacuum cleaner main body 1 and chassis 4.
12 is an exhaust hole formed on one side of the vacuum cleaner body 1 at an angle from approximately horizontal to almost directly above the bottom surface of the body; 13 is a dust case detachably attached to the vacuum cleaner body 1; Case 1
3 is provided with an intake port 14 into which a dust suction nozzle (not shown) is removably fitted; The valve body 15 that opens is fixed. 1
6 is a dust storage section provided in the dust case 13;
7 is a filter detachably attached to the opening at the other end of the dust case 13;
7 faces the blade 10 on the cleaner body 1 side when the dust case 13 is attached to the cleaner body 1. Reference numeral 18 denotes a bottomed cylindrical battery case made of synthetic resin. This battery case 18 houses the power supply battery 6 and also fixes a lead 19 constituting an electric circuit. 20 is a lid detachably attached to the rear end of the vacuum cleaner body 1;
A spring 21 is fixed inside the lid 20, and the spring 21 presses the battery case 18 toward the lead 7 side.

In the above configuration, when the power switch 3 is operated to energize the motor 5, the blades 10 rotate and the dust suction nozzle (not shown) connected to the intake port 14 is activated.
Air is sucked into the dust case 13 through the intake port 14. Therefore, when the dust suction nozzle (not shown) is directed toward the dust on the floor in order to suction and remove the dust on the floor with this small electric vacuum cleaner, the dust flows into the dust case 13 through the intake port 14 along with the air. The dust is sucked into the dust case 13
The dust is captured by the filter 17 inside and accumulated in the dust storage section 16. In addition, the air sucked together with dust is transferred to the filter 17, the blade 10, and the air guide 1.
1 and is discharged to the outside from the exhaust hole 12.

Next, the position of the exhaust hole 12 will be explained based on FIG. 3. As described above, this exhaust hole 12 is provided to exhaust air from a position approximately horizontal to almost directly above the lower surface of the main body on one side of the front side surface of the cleaner main body 1, and the air opposite to this exhaust hole 12 is A notch 22 is provided in the guide 11, and a guide rib 23 is integrally formed in order to efficiently discharge the air discharged by the rotation of the blade 10 diagonally upward from the exhaust hole 12. Note that arrow A indicates the direction of rotation of the blade 10, and arrow B indicates the direction of air discharge.By setting the air in such a direction, it is possible to use the discharged air for cleaning during use. Dust on the floor or tatami surface will no longer be blown away, or exhaust air will no longer be blown onto the human body.

As described above, in this invention, the exhaust hole is provided only on one side of the front side of the vacuum cleaner body, and the guide rib that sets the exhaust direction diagonally upward is provided on the upstream side of the exhaust hole, so it is easy to use. It is possible to provide an easy-to-use compact electric vacuum cleaner that does not cause dust to be blown away by the exhaust air or cause discomfort due to the exhaust air being blown onto the human body.
