Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner.

When disposing of the garbage accumulated in the dust collection chamber, it is often used to first remove the dust collection case and then remove the filter, but this is cumbersome as the dust collection case and filter must be attached and removed each time. It is also troublesome to carry the dust collection case to the garbage disposal site. In particular, when throwing away garbage, light dust flies up and is unsanitary. Some people put a bag in a dust case and transfer the rubber, but the trash falls out before they put the bag in, and it's a hassle to inflate the bag and set it up.

Because of this, technology was developed in which the bag automatically inflated when it was ready for use.
It is described in Publication No. 33660. In other words, the negative pressure side of an electric blower is connected to the outer circumference of the bag, and when the electric blower is activated, the external pressure becomes lower than the internal pressure of the bag, and the bag automatically inflates. It is. however,
When using this method, the pressure at the outer periphery of the bag must be reduced to negative pressure, so the storage chamber in which the bag is stored must be constructed to maintain sufficient airtightness from the outside air. It is.
However, since the bag storage chamber cannot be made from one single part and is assembled from multiple parts, it is extremely difficult to maintain airtightness. This leads to a decrease in power.

This invention was made in view of the above points, and an object of the present invention is to provide a vacuum cleaner that can have a function of automatically inflating a bag with a simple structure and does not reduce its dust suction ability. That is.

This invention includes an electric room for storing an electric blower;
A dust collection chamber that communicates with the intake side of this electric chamber and houses a filter, and a holding cylinder located below this dust collection chamber that removably fits and holds the dust disposal bag in an open state with the dust disposal bag facing upward. A main body is provided with a bag collection storage provided therein, and an opening/closing mechanism is provided between the dust collection chamber and the bag storage chamber to selectively open and close the space between the two chambers,
The main body is characterized in that a passage is provided in the main body for supplying part of the exhaust air from the electric chamber to the inside of the holding cylinder. That is, when cleaning, the opening/closing mechanism is closed to collect dust in the dust collection chamber, but after use, by opening the opening/closing mechanism, the garbage in the dust collection chamber can be transferred to a dust disposal bag that opens in the bag storage chamber. At this time, the garbage disposal bag receives exhaust pressure during cleaning and is maintained in an inflated state, making it possible to easily transfer the garbage without spilling it.
The structure is such that the garbage disposal bag can be easily set.

An embodiment of the present invention will be described based on the drawings.
Reference numeral 1 denotes a main body that is installed in a fixed position, and in this main body 1, an electric chamber 2 and a dust collection chamber 3 are formed in communication with each other, and a bag storage chamber 4 located below the dust collection chamber 3 is formed. Further, an accessory storage chamber 5 located below the electric power chamber 2 is formed with a door 6 so as to be openable and closable. The electric blower 7 is housed in the electric chamber 2, and an exhaust hole 8 is formed therein. A net filter 9 having a semicircular cross section and a densely meshed bellows-shaped filter 10 located above the net filter 9 are removably housed in the dust collecting chamber 3. Also,
In the dust collection chamber 3, cover pieces 11 located above the net filter 9 are arranged in a chevron shape and are held on a support shaft 12 so as to be movable up and down, and the lower ends of these cover pieces 11 are supported on a stopper shaft 15. ing. Further, a lever 14 is rotatably held in the dust collection chamber 3, and pushes up the cover piece 11 from below when pressed by the operating section 13 (FIG. 6). Further, a dust removing body 16 for removing dust from the filter 10 is attached to the handle 1.
7 and is rotatably provided. Further, in the dust collection chamber 3, a cylindrical suction port 18 which opens into the space surrounded by the net filter 9 is formed facing an opening 19 formed in the door 6.

Next, on the inside of the dust collection chamber 3, a slope 20 is formed which becomes narrower as it goes downward, and a rectangular cylindrical holding cylinder 21 is connected on an extension of this slope 20. A long cylindrical band 22 made of a plastic film sheet is opened toward the top of the holding cylinder 21 and is fitted and held in a bellows-like manner so that it can be dragged downward. This cylindrical band 22 is cut into dust disposal bags 23 units sequentially from the bottom.
A through hole 24 is formed in the upper circumferential wall of the cylindrical band 22, and this through hole 24 is communicated with the exhaust side of the electric chamber 2 through a passage 25.

Next, a packing 26 is fitted into the upper part of the holding cylinder 21, and a rotating body 27, which is an opening and closing mechanism, is provided while being sealed by this packing 26. The rotary body 27 integrally has a shaft 28 located at the center of the radius of the net filter 9 and rotatably held on the wall of the main body 1. The rotating body 27 closes the lower opening of the net filter 9, and ribs 29 are formed on both side edges of the rotary body 27 to be joined to the inner surface of the net filter 9, sloping inwardly as it goes downward. A space 30 is formed between these ribs 29 and the outer edge of the rotating body 27. A handle 31 is provided at one end of the shaft 28 of the rotating body 27 (FIG. 4).

Further, the bag storage chamber 4 is provided with a door 33 that rotates about a shaft 32 to open the bag storage chamber 4. This door 33 has a facing wall 35 opposite its surface 34. A welded portion 36 is also provided. This welded portion 36 is connected to the opposing wall 35.
It consists of a pressing body 37 made of a heat-resistant material fixed to one edge of the bag, and two heaters 39 and 40 supported by a support base 38 fixed to the bag storage chamber 4 and facing the pressing body 37. Further, a cutter 41 is provided on the support base 38 so as to be movable while being urged outward.

In such a configuration, the accessories such as the flexible hose 42, extension pipe 43, and suction tool 44 taken out from the accessory storage chamber 5 by opening the door 6 as shown in FIG.
After closing the door 6 as shown in FIG. 1, it is connected to the suction port 18. When the electric blower 7 is driven, the outside air containing dust is sucked from the suction port 18 into the space between the net filter 9 and the rotating body 27 of the dust collection chamber 3, and is purified by the net filter 9 and the filter 10 while being purified by the exhaust hole 8. released from. Therefore, coarse dust is collected inside the net filter 9, and fine dust that has passed through the net filter 9 is captured by the filter 10. At this time, since the exhaust air is supplied to the inside of the tube band 22, the tube band 22 swells greatly. Therefore, after cleaning, turn the handle 31 to remove the rotating body 27.
By reversing the dust collection chamber 3, the dust inside the tube belt 2
It can be transferred to 2 without spilling.
Dust removal from the filter 10 is performed by turning the handle 17 to drive the dust remover 16. However, since the cover 11 exists on the net filter 9, the rate at which the dust falling from the filter 10 adheres to the net filter 9 is reduced. Most of it falls into the recess 30. When the operating portion 13 is pressed several times, the cover piece 11 is pushed up by the lever 14 and moves up and down, allowing dust on the cover piece 11 to fall into the recess 30 as required. The dust guided by the slope 20 and falling into the recess 30 is transferred to the rotating body 27
When it is turned over, all of it can be transferred to the bottom of the tube band 22. Since the ribs 29 rub the inner surface of the net filter 9 when the rotating body 27 rotates, dust can be removed from the net filter 9 at the same time.
Next, when the door 33 is opened, the opposing wall 35 pulls the tube strip 22 filled with garbage, but the pressing body 37 pulls the tube strip 22.
2 is pressed against the heaters 39 and 40, so the cylinder band 22
is sealed over two strips, and then the cutter 41 cuts the sealed space by pressing the cutter 41. Therefore, sealing can be performed simultaneously by opening the door 33. The cutter 41 cuts and cuts the long cylindrical band 22 into dust disposal bags 23 units. Further, the lower heater 39 is located below the edge cut by the cutter 41 and seals the opening edge of the garbage disposal bag 23, and the upper heater 40 is placed below the edge cut by the cutter 41 to seal the opening edge of the garbage disposal bag 23.
3, the bottom of the tube band 22 that is pulled out downward is sealed.

The length of the tube belt 22 is about 30 times the length required for one time of dust removal, but even if dust removal is performed once a month, it will not need to be set for two to three years. The dust disposal bag 23 is not obtained by cutting the tube band 22, but may be fitted into the holding tube 21 one by one. In this case, only one welded portion 39 is required. Further, the cutter 41 becomes unnecessary.

Since this invention is configured as described above, by opening the opening/closing mechanism after cleaning, the garbage in the dust collection chamber can be transferred to the garbage disposal bag opened in the bag storage chamber, and at this time, the garbage disposal bag is opened. During cleaning, the dust is maintained in an inflated state under the exhaust pressure, making it easy to transfer trash without spilling it, and it is also easy to set up garbage disposal bags without getting your hands dirty in the trash-free bag storage room. The function of automatically inflating the garbage disposal bag in this way is due to the exhaust pressure from the exhaust air introduced into the interior of the garbage disposal bag, so the bag storage room is kept airtight. There is no need to hold the bag, and this allows the bag to be inflated with a simple structure.
Since there is no need to communicate the intake side of the electric blower with the bag storage chamber, the dust suction capacity is not reduced.
