摘要： PROBLEM TO BE SOLVED: To improve functional convenience for use by improving reduction of noise and durability while providing a mechanism for turning a suction tool in a 90-degree arc clockwise and counter-clockwise by simple and light torsional operation.
SOLUTION: This vacuum cleaner includes: a dust collecting chamber 3 at a lower opening 4; a suction port 9 for sucking the air containing dust in the dust collecting chamber 3; a main joint part 5 and a subsidiary joint part 6, which have joints in the vicinity of the suction port 9; a connecting pipe 7 at the end of the subsidiary joint 6; and a joint pipe 8 formed of flexible material, which is provided in the interiors of the main joint part 5 and the subsidiary joint part 6 to connect the suction port 9 and the connecting pipe 7, wherein the connecting pipe 7 is twisted to the right and left, whereby the suction tool is turned in a 90-degree arc clockwise and counter-clockwise so that dust near the wall of a room and dust in a narrow space between pieces of furniture can be cleared away by simple twisting operation, and it is convenient for use. Furthermore, since the joint pipe 8 is freely bent and gently bent, a passage for air is neither narrowed nor bent so that wind noise can be reduced and the construction is simplified to decrease the number of parts.

摘要： PROBLEM TO BE SOLVED: To provide a vacuum cleaner which maintains strong sucking force for a long period of time and reduces a load on the maintenance of a filter unit.
SOLUTION: A filter unit 20 for a cleaner comprises a porous PTFE membrane 21c arranged on the farthest upstream side and a nonwoven fabric 21d pasted on the PTFE membrane on the downstream side, wherein the nonwoven fabric 21d is pleated and the open angle of the pleat is 15°to 30°. By this, dust on the surface of a filter medium 21 is easily removed by adding impact to the filter unit 20, and consequently a vacuum cleaner using the filter unit 20 maintains strong sucking force for a long period of time and reduces a load on the maintenance of the filter unit.

摘要： PROBLEM TO BE SOLVED: To provide a garbage treating machine by which the original volume and weight of garbage are reduced by drying it, the garbage is never decomposed or mildewed even when let stand, much labor is not required in the post treatment, and the garbage is efficiently crushed and agitated. SOLUTION: The garbage in a garbage container 2 is crushed and agitated by a fixed blade provided to the inner wall of the container 2 and a rotary blade 5 furnished to the inner bottom of the container 2, and at least the rotary blade 5 is intermittently operated. The garbage introduced into the container 2 is crushed, agitated, heated by a heater 8 and dried. Although the crushed and dried garbage is left in the container 2, the water activity is lowered due to the dryness, and hence the garbage is never decomposed or mildewed even when held in the container 2. Further, since the rotary blade 5 is intermittently operated, the garbage is crushed and agitated more efficiently.

摘要： PROBLEM TO BE SOLVED: To provide a garbage treatment machine for drying garbage and treating the dry kitchen waste so as to avoid putrefaction of the garbage. SOLUTION: This treatment machine is provided with: a drying chamber 9 for drying garbage; a rotary cutting blade for agitating the garbage in the drying chamber 9; a motor 14 for driving the rotary cutting blade; a heating/ drying means for supplying hot air to the drying chamber 9; a motor current detection unit 19 for detecting electric current passing through the motor 14; and a rotational direction switching unit 20 for reversing the rotational direction of the motor 14 when the detected current value transmitter from the motor current detection unit 19 exceeds a preset value. Thus, in the treatment machine, garbage is heated and dried by the hot air supplied from the heating/drying means and putrefaction of the garbage is hardly occures. Also, during the drying, the garbage is agitated by the rotary cutting blade to effect a high drying rate and lesser non uniformity in drying. Further, when any torque exceeding a preset value is applied to the rotary cutting blade, the application of such excessive torque is detected by the motor current detection unit 19 and the rotation of the rotary cutting blade is reversed to solve locking trouble of the rotary cutting blade.
