Description

[Detailed description of the invention] The present invention relates to the improvement of a vacuum cleaner, and is an economical vacuum cleaner that can be easily assembled and disassembled by providing a parts mounting table on the upper surface of the bulkhead of the main body that is sandwiched between the upper and lower parts. This is what we are trying to provide.

Conventionally, in this type of vacuum cleaner, the main body bulkhead is sandwiched between the bottom and top of the main body, and the main body switch, suction amount display device, etc. are installed on a parts mounting table formed on the upper surface of the main body. The parts were secured with a lid. With this method, in order to separate the top of the main unit from the bottom of the main unit for overhaul, etc., the top of the main unit cannot be lifted unless the lid is removed and the main switch is disconnected.
It was troublesome to disassemble. Furthermore, since a lid is required, the number of parts is large and the cost is poor.

The present invention solves the above-mentioned conventional drawbacks, and includes a lower part of the main body with an open upper surface and a built-in electric fan, an upper part of the main body that closes the upper surface of the lower part of the main body, and a main body that is clamped between the upper and lower parts of the main body. It has a main body partition that is located approximately vertically and supports an electric fan and a dust collector,
At the top of the main body bulkhead, a component mounting table that opens upward is formed, and a part of the main body closes the upper opening of the component mounting table, and the suction amount is displayed on the bulkhead and the main body. The device has a configuration in which a storage space is formed for the functional parts of the device, etc., so that the storage space is exposed by removing the upper part of the main body, and the functional parts can be easily maintained at the same time.

Next, its effect will be explained. As shown in FIG. 2, the main body partition 8 has an annular projection 9 projecting rearward to support the electric fan 3, and a box-shaped projection 12 projecting forward.
is projected and brought into contact with the filter packing 11 of the filter holder 10 to prevent air leakage. The attachment/detachment of the dust collection box 22 is carried out by detaching the connecting pipe 35 from the gasket 25 of the dust collection box 22, holding the gasket retainer 24, and pulling it out. To remove dust from the filter operation 10, when the dust removal knob 31 protruding from the opening at one end of the dust collection box 22 is rotated, the dust removal spring 29 fixed to the dust removal plate 30 is also rotated, and the dust is removed onto the vibrating body 28. The spring 29 contacts and applies vibration to shake off dust attached to the corrugated filter medium 26. When removing the filter handle 10 from the dust collection box 22, pull it out from the dust collection box 22 by grasping the handle formed to protrude from the dust removal frame 32. The main body switch 18, the suction amount display device 19, the connection terminal 20, etc. installed on the component mounting table 16 formed on the upper surface of the main body partition 8 are stored by covering the main body top 2 from above. Even when the upper body 2 is removed for repair or the like, only the upper body 2 is separated from the lower body 1, and the components on the component mounting table 16 remain on the component mounting table 16 as they are.

As described above, according to the present invention, when assembling the product, it is only necessary to install the main body switch suction amount display device etc. on the parts mounting table of the main body bulkhead and then cover the main body.
There is no need to pass the lead wire from the bottom of the main body onto the main body and connect the wires on the component mounting table on the main body, as in the conventional case, and the assembly work can be streamlined. Furthermore, since the lid of the parts mounting table on the main body partition wall can also be used on the main body, the number of parts can be reduced, resulting in a more economical effect. Furthermore, if you remove the top of the main body,
Functional parts such as the main body switch and suction amount display device housed in the storage space are exposed, which has the effect of facilitating disassembly and repair.

In addition, since the above-mentioned parts and the mounting table are formed independently from the electric fan storage section and the dust collector section, the fine dust being sucked and exhausted does not come into contact with the various parts of the component mounting table. Failures due to fine dust adhering to parts will not occur. In other words, various parts are installed above the main body partition wall that is installed approximately perpendicular to the floor surface, and the upper case is closed from above, which is approximately perpendicular to the main body partition wall, so that it is possible to separate the airflow from the dust collection section side. This prevents collected dust from adhering to various parts. Moreover, since the component mounting table is formed on the upper part of the main body partition, various parts related to either the electric fan storage section or the dust collector section can be easily collected on this component mounting table.

Furthermore, if the main body partition and the component mounting table are integrally formed as in the embodiment, a strong component mounting table with fewer parts can be obtained. Furthermore, as in the embodiment, if the component mounting table is fitted into the hose winding portion which is integrally formed with the component mounting table protruding from the main body, there is no waste of space and a compact vacuum cleaner can be provided.
