Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a dust collection box for a vacuum cleaner, and particularly to an opening/closing device for a lid thereof.

(Prior Art) Generally, a dust collection box has a handle on the top surface and an opening on the front side, and a lid body that opens and closes the front opening of the dust collection box, and dust inside the dust collection box is removed from the lid body. In vacuum cleaners that are opened and disposed of through the front opening, if the lower end of the lid is pivoted so that the lid opens downward, dust will fly up when the lid is opened and disposed of, which is unsanitary. .

However, recently, in such vacuum cleaners, by pivoting the upper end of the lid and pressing an operation button near the handle, the lid can be opened upward and the dust inside can be disposed of. Things are being commercialized.

Its structure is such that the lid has a double wall structure with a cavity inside, an interlocking rod is inserted into the cavity of the lid so as to be movable up and down, and an engaging part is provided at the lower end of the interlocking rod.
The lid is held in the closed state by engaging this engaging part with the locking part at the lower end of the front surface of the dust collection box, and the interlocking rod is moved downward by pressing the operation button near the handle and engaged. The lid body can be opened upward by removing the part from the locking part. According to this structure, it is possible to hold the dust collection box with one hand and operate it with that hand to open the lid upward, allowing the dust inside the dust collection box to be disposed of easily and hygienically. It has the advantage of being able to be processed.

(Problems to be solved by the invention) By the way, in the above-mentioned conventional structure, the lid body has to have a double-wall structure, and an interlocking rod and a spring for biasing it upward must be built inside. This not only complicates the structure of the lid, but also increases the weight, thickness, etc. of the lid, which is not preferable in terms of handling.

However, the present invention makes it possible to dispose of dust easily and hygienically by opening the lid upward, and at the same time simplifies the structure of the lid and reduces its weight and thickness by omitting the interlocking rod. It was designed to be measurable.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a mounting piece having a vertically elongated hole at the top of the front surface of the dust collection box, and attaches a pivot shaft to be inserted into the long hole of the mounting piece. By supporting the upper end of the lid, the lid is rotatably and vertically movable relative to the mounting piece. A spring member is provided to constantly bias the pivot upward, and an engaging portion is provided at the lower end of the lid that engages and disengages from the locking portion at the lower end of the front surface of the dust collection box when the lid moves up and down. , the pivot is configured to move downward as the operating button is pressed.

(Function) In the above configuration, the lid body closes the front opening of the dust collection box by keeping the engagement part at the lower end engaged with the locking part of the dust collection box by the force of the spring material. .

In this state, by pressing the operation button near the handle and moving the pivot downward, the lid body is moved downward and its engaging part is released from the locking part, and the lid body acts in the normally open direction. It can be opened upward by the biasing force of the spring. Therefore, the dust inside the dust collection box can be disposed of through the front opening of the dust collection box.

(Example) An example shown in the drawings will be described in detail below.

The main body handle 9 is fitted into a notch 11 formed in the top cover 10 of the dust collecting box 6 so as to be flush with the top surface of the vacuum cleaner main body 1. Reference numeral 12 designates a handle formed integrally with the dust collection box 6, and the dust collection box 6 is carried by inserting a hand through a notch 11' of the top cover 10. As shown in FIG. 3, the dust collection box 6 has an open front face, and a ""-shaped primary filter 13 is provided inside the dust collection box 6, and a secondary filter 15 is provided behind the primary filter 13 with an appropriate gap 14 in between. . The primary filter 13 collects relatively coarse dust, and the relatively fine dust that has passed through the primary filter 13 is collected by the secondary filter 15. 16 is a gasket attached to the rear of the secondary filter 15. 17 is a lid for opening and closing the front opening of the dust collection box 6, and in the center thereof, an inlet 19 having a suction opening gasket 18 is provided opposite to the inlet 7;
A seal packing 17a is attached to the inner peripheral edge. Further, a hook-shaped engaging portion 21 is formed at the lower end of the lid 17, and the hook-shaped engaging portion 21 is removable from the locking portion 20 formed at the lower portion of the dust collection box 6. It has a letter-shaped bent piece 22 and bearing pieces 23, 23 provided at an appropriate interval, and a stopper 24 is formed at the vertical part of the bent piece 22 located between these bearing pieces 23, 23. . Reference numeral 25 denotes a pivot rotatably supported between the bearing pieces 23, 23 using a speed nut 26, etc., and an L-shaped bent piece from the mounting board 27 attached to the upper surface of the dust collection box 6. It is vertically movably inserted into vertically long holes 29, 29 formed in mounting pieces 28, 28 that protrude toward the 22 side. Reference numeral 30 denotes a plate spring (spring material) attached to the upper surface of the dust collection box 6 together with the mounting board 27, and its free end is connected to the pivot 25 (and by extension, the lid 1).

Reference numeral 31 denotes a coil spring wound around the outer periphery of the pivot shaft 25 so as to apply rotational force to the lid 17. One end of the coil spring is engaged with the free end of the mounting piece 28, and the other end is attached to the stopper 24. It is locked. Therefore, a force that rotates the lid body 17 about the pivot 25 as a fulcrum due to the biasing force of the coil spring 31 and a force that pushes it upward due to the biasing force of the leaf spring 30 are constantly acting on the lid body 17. Long holes 29, 29 of mounting pieces 28, 28
When it moves downward against the biasing force of the leaf spring 30,
The lid body 17 also moves downward and engages the locking portion 20.
The engagement portion 21 is disengaged, the lid 17 is rotated clockwise about the pivot 25 by the urging force of the coil spring 31, and the front opening of the dust collection box 6 is opened. If you want to close the front opening of the dust collection box 6, hold the lid 17 in your hand and turn it counterclockwise. When the locking portion 20 of the locking portion 20 comes into contact with the lid body 17 and the lid body 17 is further rotated counterclockwise, the lid body 17 moves slightly downward due to the sliding contact between the locking portion 20 and the inclined portion 21a of the engaging portion 21, and the lid body 17 is engaged. When the hook portion of the mating portion 21 passes over the locking portion 20, the two are engaged and locked.

Reference numeral 32 is an operation button for releasing the lock, and is rotatable about a pin 33 as a fulcrum.
It has a structure in which it protrudes from the top cover 10 near the top cover 10 . An engaging claw portion 35 is integrally molded at the bottom of the operation button 32, and a tongue piece 36a of an operating lever 36 is engaged with the engaging claw portion 35. The operating lever 36 is rotatable about a shaft 37 installed between the mounting pieces 28, 28, and its free end engages above the pivot 25 in order to press the pivot 25 downward. are combined. That is,
When the operating button 32 is pressed against the biasing force of the spring 34, the engaging claw portion 35 at its free end moves upward and rotates the operating lever 36 counterclockwise. The tip is designed to press the pivot shaft 25 downward.

Here, the operation of the present invention will be explained. Now, when the electric blower (not shown) is driven with the dust collection box 6 stored in the storage part 4 of the vacuum cleaner body 1, air containing dust passes through the intake port 7 and the intake port 19 into the dust collection box. 6, where only relatively coarse dust is passed through a "" type primary filter 13, and fine dust that has passed through the primary filter 13 is collected by a secondary filter 15. Then, only the purified air is discharged to the outside through the ventilation holes 2 of the partition wall 3, an electric blower, and an exhaust port (none of which are shown). In this way, dust is collected in the dust collection box 6, and when discarding this dust, use the main body handle 9.
stand up, insert your hand through the notch 11', hold the handle 12 of the dust collection box 6, and take out the dust collection box 6 from the storage section 4 of the cleaner body 1. Then, the user brings the dust collection box 6 to a suitable location and presses the operation button 32 with his or her thumb. Then, the engaging claw portion 35 at the lower end of the operating button 32 rotates clockwise about the pin 33, and at this time the tongue piece 36a of the operating lever 36 is lifted. Therefore, the operating lever 36 is connected to the shaft 3
7 in a counterclockwise direction, and its free end pushes down the pivot 25. For this reason, the lid body 1
7 moves slightly downward, and the engagement part 21 at the lower end of the lid body 17 and the engagement part 20 of the dust collection box 6 are disengaged.
The lid 17 is rotated clockwise about the pivot 25 by the biasing force of the coil spring 31, and the front opening of the dust collection box 6 is opened. Therefore, the dust collected in the dust collection box 6 can be thrown away through the front opening of the dust collection box 6, and the fine dust collected between the primary filter 13 and the filter 15 can be removed from the primary filter 13. The dust is discharged to the outside through a passage formed between the dust collection box 6 and the bottom surface of the dust collection box 6. In addition, when closing the front opening of the dust collection box 6 with the lid 17, the lid 17 is rotated counterclockwise against the biasing force of the spring 31, and its lower end is engaged. It is only necessary to engage the part with the locking part 20 on the dust collecting box 6 side.

(Effect of the invention) As described above, according to the structure of the invention, it is possible to hold the dust collection box with one hand and open the lid with that hand.
Furthermore, by opening the bottom of the lid, dust can be disposed of easily and hygienically.Furthermore, by pressing the operation button, the pivot is moved downward, and the lid is moved downward. Since the engaging part is released from the locking part, there is no need for the lid to have a double-walled structure and an interlocking rod that moves up and down inside, and a simple plate-shaped one is sufficient. This not only simplifies the structure of the lid, but also reduces the weight and thickness of the lid, making it extremely easy to handle.
