Description

[Detailed description of the invention] b) Industrial application field This invention relates to a vacuum cleaner that is removably housed in a vacuum cleaner case.

Conventional technology Conventionally, in vacuum cleaners in which a paper bag-like filter is inserted and removed in a dust case by opening the intake air and removing the paper bag-like filter inside the dust case, the paper bag-like filter spread out in a circle is removed from the front cover. I had to open it up and take it out by hand,'i,
7c dust case is 7ζ which usually expands at the same time at the rear.
It is difficult to get it out of the opening provided in the previous issue. If you try to pull it out forcibly, the paper bag-like filter will be damaged, and you will have to collect it at 7.
There was a problem when the dust settled down.There is also a case where a paper bag-shaped filter is attached to the front opening of the dust case, and the paper bag-shaped filter is discharged from the rear opening after fruit is eaten. However, it has the disadvantage that the mechanism is complicated, making it difficult to handle and increasing the cost.

C) Purpose of the Invention The present invention is a paper bag-like filler for a dust case.

2) Structure of the Invention The vacuum cleaner of the present invention includes a main body case having a built-in electric blower, a dust case having an air intake port removably connected to the main case, and a dust case provided on the upper surface of the dust case.
A filter mounting body which is removably attached to the filter insertion opening and is formed between the second insertion and removal method, and a filter mounting body which removably holds the bag opening plate of the bag-shaped filter; 7a/Featured in that it is composed of a bottom cover that can be opened and closed at will.

e) Example Embodiments of the present invention shown in the drawings will be described below.

Reference numeral 111 denotes the main body of the vacuum cleaner, which is constructed by connecting a main body case (2) and a dust case (3). The main body case (21
The electric blower (4) and cord reel (5) are arranged and stored above and below, and a pair of rear wheels +61+61 are located on both sides of the bottom.
It is set up. The dust case (3) has a handle (7) on the top.
) and a lower retaining part (
9) and the upper clamp means +1α to secure the main body case (
2) is removably connected to the front part of the

In addition, the front part of the dust case (3) has a double-walled IC, J: structure consisting of an inner plate (old) and an outer plate (112+), and an air intake port (14
) is formed. tJ9 is a back plate having a ventilation hole α61Y provided on the rear surface of the dust case (3), and the back plate has a seal gasket 0' along the ventilation port α61VC on the main case side of the back plate. 'l is provided.

Therefore, (1) a filter mounting body that is removably inserted into the filter insertion port Q9 provided on the top surface of the dust case (3), and the mounting body has a lid part Q1 with a handle. It consists of a mounting frame part (c) having mounting grooves (a) and (a) between the insertion and removal directions, and a packing 04 is attached to the lower surface side of the lid part 121).

The paper bag-shaped filter (c) attached to the filter attachment body (1, 81) has a foldable dust collection bag part ν and a bag mouth plate (a) that is stored in the bag opening of the dust collection bag part. Therefore, the mounting groove (A) of the bag opening plate (A) and the housing frame (C) are
By inserting it into the filter mounting body (181), it is held by the filter mounting body (181).

＠ is a bottom cover that closes the bottom opening of the dust case (3) so that it can be opened and closed freely; the front adjustable wheels (8) are attached to the bottom cover; The dust case (3) is rotatably supported on the main body case side, and the front part is provided with a clamp (1) that engages and disengages from the protrusion C31) provided at the lower front surface of the dust case (3). ing. The lower opening (A) of the dust case (3) has a connection with the bottom cover. ! ! ! Seal padskin (c) is attached to hold χ.

C'('Q is the bag mouth plate of the paper bag-shaped filter (C) formed protruding from the inner side of the filter mounting body (F:, h (C) so as to face the country's mounting frame part (C)) This is a supporting locking part.

Next, the state of use of the above configuration will be explained.

First, pull out the filter mounting body (Il, !17al) from the filter insertion port ■ of the dust case (3) to L 10,000,
Insert the bag opening plate ψθ of the paper bag-shaped filter (c), which has been folded into a small size and tightened, into the folding frame part of the filter mounting body from below and set it.

Next, attach the filter mounting body +1811C from the filter insertion port acJ of the tarst case (3) fl, 7'H.
When the paper bag-shaped filter (han) is inserted into the dust case (3), the lower end of the bag opening plate (goods) will be attached to the locking part of the bottom M-ring □
When it comes into contact with B1J, the B board (A) is connected to the intake rock +1.
Close to 31.

If you drive the electric blower (4) in this state, the intake air [](
L41. As the airflow flows in, the paper bag-shaped filter casing expands inside the storage case (3) due to wind pressure, as shown in Figure 3.

Then, the dust that is inhaled along with the air flow is collected in the paper bag-shaped filter (c) and becomes stagnant.When the dust accumulates in the paper bag-shaped filter (c) and the suction power decreases, the suction power decreases. Stop the operation of the electric blower (4), throw away the collected dust together with the paper bag-shaped filter (a), press the upper clamp means (1α), and remove the dust case (3) from the main case (2). Then, when the clamp (3) is pressed to release the engagement with the protrusion 31), the bottom (C) rotates as a fulcrum on the side of the main body case of the dust case 13), and the paper bag that collects the dust is removed. The filter stem) will fall off naturally due to the weight of the mouth, and you can either throw it away or complete it.

F) Effects of the Invention Since the vacuum cleaner according to the present invention is constructed as described above, the mounting set of the paper bag-shaped filter to the dust case is easy and simple since there is no need to make the dust case all steel or tilt it. It can be done reliably. In addition, when the dust case is separated from the main case and the bottom cover is opened, the paper bag-like filter will fall under its own weight, allowing for sanitary TIc dust discharge without touching the paper bag-like filter≧
