Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner with a dust compactor.

Structure of the conventional example and its problems In the conventional vacuum cleaner of this type, the dust compactor passes through the case intake □ when pressed.

Therefore, when the dust compressor is accidentally activated during operation of the vacuum cleaner, the dust may move to the back side, making it impossible for the compressor to return. Also, from the above, if the return of the compressor is locked, or even if it is not locked, if the compressor is kept pressed for a long time while the vacuum cleaner is running, the suction path to the fan motor will be cut off, causing the motor to overheat and cause a fire. There was a drawback that this occurred. Purpose of the Invention The present invention solves these conventional drawbacks, and uses a dust compressor to compress the dust in the dust case to increase the amount of dust collected. To provide a vacuum cleaner that can reliably perform a dust collecting operation even if a compressor is erroneously operated.

Structure of the Invention The vacuum cleaner of the present invention includes a main body with a built-in fan motor, a case intake □ which is located on the suction side of the fan motor and has an operable check valve, and a case in which air flows in through the case intake port. It consists of a dust case equipped with a filter device that filters dust-containing air, and a dust compressor that compresses the dust in the dust case, and a part of the dust compressor has a check valve when it is pressed and moved. The pressure movement end point is set in the middle of the same check valve.

Therefore, even if you accidentally push the dust compressor while the vacuum cleaner is running, dust will not enter the upper side, and part of the check valve will open on the lower side, allowing normal dust suction to take place. It is something.
DESCRIPTION OF THE EMBODIMENTS The embodiments will now be described with reference to the accompanying drawings.

The figure is applied to an appli-type vacuum cleaner.
1 is a main body having a handle 2 extending upward, and 3 is a suction tool pivotally attached to the lower part of the main body. The main body 2 has a space below to accommodate a fan motor 4, and has a boat-shaped case mounting portion 5 with an open front end above. Reference numeral 6 denotes a partition, 7 a vent, and 8 a main intake □ formed at the upper rear surface of the case mounting portion 5, which is communicated to the suction tool 3 via a hose 9.

10 is an exhaust port, and 11 is a rotating brush provided on the suction tool 3 and linked to the fan motor 4 via a belt 12.

Reference numeral 13 indicates a dust case detachably attached to the case mounting part 5, and a claw 14 protruding from the lower part of the dust case is attached to a locking part 15 of the partition wall 6, and a buckle 16 provided at the upper part is attached to the upper part of the case mounting part 5. They are respectively locked in the buckle holes 17.

Furthermore, the buckle 16 is attached to a handle 18 that projects toward the top of the dust case 13. The dust case 13 has a downwardly open shape, and has a case intake port 20 on the back side, which is connected to the main body intake port 8 through a packing 19 made of a flexible material such as rubber.

21 is a flexible check valve that is connected to the packing 19 at the upper part and opens and closes using this joint as a fulcrum; 22 is a filter device consisting of a primary filter 23 and a secondary filter 24; Secondary filter 2
4 is removably attached to the lower open portion of the dust case 13.

Reference numeral 25 denotes a dust compressor energized by a spring 26 so as to be normally located above the case intake port 20, and its rear end is set to move close to the check valve 21.

In the above configuration, the dust scraped up into the suction tool 3 by the rotating brush 11 is removed by the suction force of the fan motor 4 from the hose 9 → main intake □ 8 → case intake port 20 → dust case 1
3 and is captured by the filter device 22.

The purified air reaches the fan motor 4 through the ventilation port 7 of the partition wall 6, and is then exhausted from the exhaust port 10. To dispose of the dust, remove the dust case 13 from the case attachment part 5 of the main body 1, carry it to a predetermined place, and then remove the secondary filter 24 and remove the dust case 13 from the case mounting part 5 of the main body 1.
By opening the lower part of 3, this can be done easily and hygienically.

Next, by pressing the dust compressor 25 against the spring 26, the dust in the dust case 13 is compressed, and the amount of dust collected is substantially increased.

Therefore, the number of times the above-mentioned dust removal operation is performed can be reduced by the increase in the amount of collected dust. By the way, when the dust compressor 25 is pressed and moved, the rear end is close to the check valve 21, so even if the vacuum cleaner is in operation, that is, the check valve 21 is moved by the dashed-dotted line in FIG. Even when it is opened as shown in the figure, it is closed from above in response to the movement of the compression body 25.

Here, the lowering end point of the dust compressor 25 is set in the middle of the check valve 21 as shown by the dotted line in FIG. Therefore, the check valve 21 closes above the compression body 25 and partially opens below it as shown by the dotted line.

As described above, even if the dust compressor 25 is erroneously pressed during operation of the vacuum cleaner, dust will not circulate to the back side of the body or the intake system of the fan motor 4 will not be cut off.

In the above embodiment, an applicator type vacuum cleaner has been described, but the present invention can of course be applied to other types of vacuum cleaners.

Effects of the Invention As described above, the present invention has a main body with a built-in fan motor, a case intake □ which is located on the suction side of the fan motor and has an operable check valve, and a case intake □ which is located on the suction side of the fan motor and has an operable check valve. It consists of a dust case equipped with a filter device that filters dust air, and a dust compressor that compresses the dust in the dust case, and a part of the dust compressor is in close proximity to the check valve when the dust compressor is moved under pressure. In addition, since the end point of the pressing movement is set in the middle of the check valve, locking accidents of the dust compactor can be reliably prevented, and operability and stability are improved by eliminating overheating and ignition of the fan motor. This makes it possible to provide a vacuum cleaner with excellent performance.
