Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a front lid opening operation button in a front lid opening/closing type vacuum cleaner.

Conventionally, vacuum cleaners have been manufactured in which a front lid that can be opened and closed is provided on the front surface (dust suction side) of a dust collection box in order to easily remove collected dust. However, the opening button was difficult to operate when opening the front cover, making it inconvenient to use. This is because the front lid and the dust collection box are airtightly crimped together through the lid rubber, so it is difficult for the front lid buckle to separate from the hook on the dust collection box even with a small force. Naturally, if you make it smaller, it will be easier to operate the opening button, but this will reduce the airtightness and the dust collection performance.

In order to solve the above-mentioned drawbacks of the conventional example, the present invention provides an operation button that uses a lever and makes the operation part a shape that allows easy application of finger force, thereby improving operability without reducing airtightness. To provide a front lid opening operation button for a vacuum cleaner. Hereinafter, embodiments will be described in detail with reference to the drawings.

FIG. 1 shows the appearance of one embodiment of the present invention, in which 1 is a vacuum cleaner body having an electric blower inside, 2 is a dust collection box with a built-in filter device, and 3 is a vacuum cleaner body having an electric blower inside.
5 is a front lid that is equipped with an intake hole 4 to which a hose is connected and is attached to the dust collection box 2 so that it can be opened and closed; 5 is a handle;
Reference numeral 6 denotes an operation button to be operated when opening the front cover 3.

Fig. 2 shows the internal configuration, where 7 is an electric blower, 8 is a main filter installed in the dust collection box 2,
A prefilter 9 is arranged in front of it. The front lid 3 can be opened and closed around a hinge made up of a hinge fitting 10 and a hinge shaft 11 attached to the dust collection box 2, a hinge contact plate 12 attached to the front lid 3, and a hinge spring 13. . A buckle 14 is provided at the lower part of the front lid 3, and is adapted to be hooked onto a hook 15 of the dust collection box 2 and fixed. 16
is a lid rubber that makes the space between the front lid 3 and the dust collection box 2 airtight when the front lid 3 is closed.

The operation button 6 is formed into a substantially L-shape, with a bent portion 6b serving as a pivot point, one end 6a serving as a force point for operation, and the other end 6c serving as a point of action for pushing down the front cover 3. 17 is the point of action 6c of the operation button 6
It is a spring that always urges upward. Operation button 6
As shown in FIG.
When the distance to B is B, the dimension is such that B≧A, and the opening angle α between the force point 6a and the action point 6c is set to α≧90°. Also, emphasis point 6a,
That is, the operating surface is slightly inclined forward and upward, and its tip is protruded to make it easier to rest your fingers on it. Note that the operating surface may be knurled to prevent the finger from slipping. The operation button 6 is arranged so that the point of effort 6a is located slightly behind the fulcrum 6b. In addition, 18 is the vacuum cleaner body 1
and a buckle button for attaching and detaching the dust collection box 2, 19 is the front wheel,
20 is the rear wheel.

In this embodiment configured as described above, when you put your thumb on the force point (operation surface) 6a of the operation button 6 and push it forward (in the direction of the arrow in FIG. 3), the point of action 6c moves downward, and the front cover 3 Push down the top of the buckle 1
4 is removed from the hook part 15 of the dust collection box 2, the front lid 3 is opened by the spring force of the hinge spring 13, and the dust inside the dust collection box 2 can be easily removed. in this case,
Since the relationship between the distance B from the fulcrum 6b to the point of force 6a and the distance A from the fulcrum 6b to the point of action 6c is B≧A, even if the force of the finger operating the force point 6a is relatively small due to the lever principle. The force for pushing down the front cover 3 is increased, and the buckle 14 can be easily removed. In addition, the opening angle α of the operation button 6 is α≧90°, and the force point 6a is located slightly rearward from directly above the fulcrum 6b, so that when force is applied to the force point 6a, the force point 6a passes directly above the fulcrum 6b. Therefore, the direction of the force applied to the force point 6a is directed forward and upward, and combined with the shape of the force point (operation surface) 6a, there is no slippage of the fingers, making it easy to apply force and ensure reliable operation. This is possible.

As explained above, according to the present invention, it is possible to open the front cover with a relatively small force, and the operability is improved by preventing fingers from slipping on the operating surface. This has the advantage that dust can be easily disposed of without reducing performance or dust collection ability.

Claims (1)

[Claims] 1. A front lid is provided to cover the front part of a dust collection box having a filter, and the front lid has a hinge part at the top, a buckle at the bottom to be hooked to the dust collection box, and an airtight space between the dust collection box and the dust collection box. In a vacuum cleaner, the vacuum cleaner has a lid rubber that can be opened and closed about the hinge part, and has a roughly L-shape, and the bent part is pivoted on a fulcrum, and one end is attached to the top of the dust collection box. The other end is located at the front of the dust collection box and serves as the point of action for pushing down the front cover and removing the buckle from the dust collection box;
When the distance from the fulcrum to the point of action is A, and the distance from the fulcrum to the point of force is B, B≧A, and when the opening angle of the bending part is α, α≧90°, and the point of force A front lid opening operation button for a vacuum cleaner, characterized in that the front lid opening operation button is located directly above or slightly behind the fulcrum, and the operation surface thereof is inclined upward toward the point of action.
