Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general household vacuum cleaner.

[0002]

2. Description of the Related Art A conventional vacuum cleaner will be described with reference to FIGS.

A conventional vacuum cleaner is disclosed in Japanese Patent Application Laid-Open No. 9-1920.
An electric blower 101, a dust box unit 102 including a dust box body 112 and a filter unit 113, and a rotating brush 1 are shown in FIG.
03 is gathered in the main body nozzle part 104, and the handle 105 is a vacuum cleaner coupled to the main body nozzle part 104, and the outer periphery of the main body nozzle part 104 is constituted by the main body upper member 106 and the main body lower member 107, A certain electric blower 10
1. The dust collection box unit 102 and the rotating brush 103 are supported or held by the upper member 106 and the lower member 107. With this configuration, in the case of repair or the like, the repair and the internal check cannot be performed without removing all the screws fastening the upper member 106 and the lower member 107 of the main body nozzle portion 104. In recent years, in order to give a sense of unity from the design point of view, the upper member 106 of the main body nozzle portion 104 is prevented from entering a parting line of parts.

Further, a dust suction port 109 provided in the rotating brush chamber 108 in the main body nozzle portion 104 and connected to the dust collection box unit 102 is provided in the center of the main body nozzle portion 104,
Dust is scraped out of the floor by the rotating brush 103 and is sucked into the dust collection box unit 102. Electric blower 101
The suction passage 110 is provided on the belt side from substantially the rear center of the dust collection box unit 102. Dust is a rotating brush 1
03, is scraped out of the floor, passes through the dust suction port 109,
Since the exhaust port 111 and the dust inlet 109 of the dust box unit 102, which enter the dust box unit 102 but are connected to the suction passage 110 from the electric blower 101, have little positional deviation, dust accumulates from the center. In some cases, the dust did not accumulate at the corners of the dust box unit 102, and the dust was not sucked in even though the dust was not sufficiently accumulated in the dust box unit 102.

The main body switch 114 is attached to a lower member of the main body nozzle portion 104 and is turned on and off by a foot pedal 115. Body switch 1
Reference numeral 14 denotes an electric blower 101, which is provided with a second motor 116 for driving the rotating brush 103, a safety device 117, a power supply battery 118, and a power supply battery 118.
9 is connected to a charging connection section 120 connected to a lead sensor 121.

Further, the power supply battery 118 and the electric blower 10
Reference numeral 1 is located on one side from the center in the main body nozzle portion 104.

Further, the exhaust of the electric blower 101 is performed by a main body exhaust port 1 provided in the main body upper member 106 of the main body nozzle portion 104.
It is discharged from 22. An exhaust filter 123 is attached to the main body exhaust port 122 to remove dust from the exhaust air, clean the exhaust air, and take the air out of the machine.

[0008]

However, in the above configuration, when there is a problem in the main body nozzle portion 104, the inside cannot be confirmed unless all screws holding the main body nozzle portion 104 are removed. However, there is a problem that it takes a lot of time to disassemble and check the inside.

Although dust enters the dust box unit 102 from the suction port 109, the dust box unit 102
Since the exhaust port 111 of the dust collecting box unit 102 is slightly shifted from the center of the main body and does not change, dust easily accumulates on a line connecting the intake port 109 and the exhaust port 111 of the dust collection box unit 102, and there is a problem that the performance is deteriorated. Was.

Further, when assembling the product, since the main body switch 114 and the charging connection portion 120 are separated from each other, the lead sensor 121 has to be drawn around for a long time.

In addition, since the electric blower 101 and the battery 118 are vertically arranged in the same place, and the center of gravity is shifted to one side of the main body nozzle 4, there is a problem that portability and usability are poor. Was.

When carrying the product, the handle 1
When the head 05 is lifted, the main body nozzle 104 does not lock the main body nozzle 104 and the handle 105, so that the main body nozzle 104 always falls down slowly. For this reason, the user not only lifts the main body a little, but also carries the main body nozzle portion 10 when carrying.
Unless it is lifted by the depth of 4, there is a problem that it is difficult to carry without lifting. In addition, when a configuration is adopted in which the main body nozzle portion 104 and the handle 105 are locked, the lock holding force is sufficient, but it is necessary to release the lock by stepping on the main body nozzle portion 104 when using. There was a problem that the usability was poor.

In recent years, it has become mainstream that exhaust gas is not exhausted from the vacuum cleaner, and this configuration has a problem that the exhaust gas is exhausted outside the device and is not good for the environment.

In the configuration in which the dust box unit 102 is mounted in the concave portion at the center of the main body nozzle portion 104, it is necessary to form the handle of the dust box unit 102 at the center from the viewpoint of design. In some cases, the dust collection capacity of the dust collection box unit 102 was reduced. In addition, there is also a problem that the strength is weak because there is no component there due to the upper opening.

This product is packaged in the form of a finished product with the handle 105 attached. In recent years, products tend to be smaller and lighter, and the number of packages has been reduced. Furthermore, when performing repairs, there is no lock of the handle 105, so that the product is placed in a horizontal state, and the user leans down to perform the work, making it difficult to perform the work.

Although the main body switch 114 can be turned on and off by depressing the foot pedal 115, it is difficult to use the foot, and in this case, it is difficult to use the left-handed foot. .

In addition, since the second motor 116 is used to rotate the rotating brush 103, there is a problem that the second brush 116 becomes heavy and is out of recent tendency to reduce the size and weight.

The present invention solves these problems.
