Abstract

PURPOSE:To prevent the malfunctioning of a switch as caused even when water floods a mounting part of the switch. CONSTITUTION:In a holding part of a switch 14 for operating 2 motor 5 at a maximum output, a protruded part 19 with the area thereof smaller than the undersurface of the switch 14 is formed on a planar plate 17 of a cleaner body 1. The switch 14 is placed on the protruded part 19 and the undersurface of the switch 14 is made to float by a distance from the top surface of the planar plate 17 to hold and fix the switch 14. Thus, the mounting part of the switch 14 is formed convex ant even when the water floods the mounting part of the switch 14, there is no direct infiltration of water into the switch 14 thereby eliminating malfunctioning eventually.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum cleaner for household use, industrial use and the like.

[0002]

2. Description of the Related Art A conventional vacuum cleaner of this type has a structure shown in FIGS. 3 is a perspective view of the electric vacuum cleaner, and FIG. 4 is a sectional view taken along the line AA of FIG. In these figures, 1 is an electric vacuum cleaner body having a dust collection chamber 2 in the front and a motor chamber 3 in the rear, and a dust collection bag 4 made of a paper bag or the like is housed in the dust collection chamber 2 Contains a motor 5. Reference numeral 6 is a lid that covers the upper part of the dust collection chamber 2, and one end of a hose 8 having a button 7 that can adjust the power consumption of the motor 5 is connected to the opening thereof. Reference numeral 9 is an indicator for visually recognizing the amount of dust collected, which is mainly a window 10 and a pipe 1 arranged inside thereof.
1, a pointer 12 provided in the pipe 11, a coil spring 13 for pressing the pointer 12 against the dust collecting force
Etc. Reference numeral 14 denotes a switch provided near the indicator 9 which operates at the maximum power consumption while the knob 15 is pressed, regardless of the power consumption state or stop of the electric vacuum cleaner in operation, and the knob 15 is the main body. It is provided so as not to project from the outer shell surface of 1. The switch 14 is held by a mounting portion 16 provided on the main body 1, and the mounting portion 16 has a rib 18 on a flat plate 17.
Is provided to hold the outer circumference of the switch 14.

In operation, when the button 15 of the switch 14 is pressed, the vacuum cleaner is operated with maximum power consumption regardless of the operating state and stoppage, the pressure in the dust collecting chamber 2 is reduced, and the vacuum pressure is different from the external pressure. The pressure is detected, and the detected amount can be visually recognized through the window 10 to inform the user of the time when the dust is discarded.

[0004]

However, in the structure in which the switch 14 is provided close to the flat plate 17 as described above, when water is accidentally spilled on the main body 1 during the cleaning work, etc. However, there is a problem in that the water easily enters the contact portion of the switch 14 and malfunctions.

The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an electric vacuum cleaner in which malfunction of the switch due to flooding is unlikely to occur.

[0006]

In order to achieve the above object, an electric vacuum cleaner according to the present invention is configured such that a switch mounting portion for operating a motor at maximum output has a lower surface of the switch supported by a convex portion or a switch. It is configured by providing a concave space on the lower surface of the.

[0007]

With the above structure, even if water enters the main body of the vacuum cleaner during cleaning work, the switch mounting portion has a convex or concave shape. There is no malfunction.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. 1 and the same parts as those in FIGS. To do.

According to the present invention, the flat plate 17 constituting the switch mounting portion is provided with a convex portion 19 having a used area from the lower surface of the switch 14.
Is provided, the lower surface of the switch 14 is held on the convex portion 19, and the side surface of the switch 14 is supported and fixed by the rib 20. In addition, 14 a and 14 b are a pair of terminals of the switch 14.

With the above construction, by pressing the button 15 of the switch 14 regardless of the operating state of the vacuum cleaner, the movement of the pointer 12 can always be confirmed by a constant suction force, and the dust collection amount can be accurately measured. You can know. Further, even if water is accidentally spilled on the main body 1 during the cleaning work and the water enters the mounting portion of the switch 14, the convex portion 19 holds the switch 14 on the upper side, so that the water does not directly enter. Therefore, the switch 14 does not malfunction.

FIG. 2 is a sectional view of another embodiment. In this embodiment, the terminals 14a, 1 are provided on the lower surface of the mounting portion of the switch 14.
The concave portion 21 is formed in a range wider than the lower surface area of the switch 14 in the range including 4b, and the switch 14 is held by the rib body 22 formed inside the concave portion 21.

With this structure, as in the previous embodiment, the switch 1 is accidentally spilled on the main body 1 during the cleaning operation.
Since the recess 21 is formed on the lower surface of the switch 14 even if water enters the mounting portion of No. 4, it is possible to prevent the invading water from accumulating in the recess 21 and splashing water on the switch 14, thus preventing malfunction of the switch. It won't happen.

[0013]

As described above, according to the present invention, since the mounting portion of the switch is formed in the convex shape or the concave shape, water is accidentally spilled on the cleaner body during the cleaning work and is spilled into the body. It is possible to provide an electric vacuum cleaner that does not cause malfunction of the switch because water does not directly enter the switch even if water enters.
