Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vertical vacuum cleaner having a dust collection bag.

2. Description of the Related Art Conventional vertical vacuum cleaners generally have a configuration as shown in FIGS. 3 and 4. The configuration will be described below with reference to the drawings.

In FIGS. 3 and 4, reference numeral 15 is the main body, which has wheels (not shown) for movement at the bottom. 1B is a suction fan motor built into the lower part of the main body 15, 17 is a floor nozzle pivotally attached to the lower part of the main body 15, 18 is a handle projecting above the main body 15, and 19 is a main body cover, which is the front surface of the main body 15. A dust collection chamber is formed by fitting and covering the side opening. 20 is a dust collection bag, 21 is a mouth core provided integrally with the dust collection bag 20, 22 is an intake port provided on the inner wall of the main body 15,
The intake port 22 and the dust collection bag 20 are connected to the mouth core 21 and the bag holder 23.
connected via. 24 is a hose that communicates the floor nozzle 17 and the intake port 22.

The dust-containing air flowing in through the floor nozzle 17 passes through the hose 24 and reaches the dust collection bag 20, where it collects dust.

Dust is further removed by a filter 25 provided below, and only purified air passes through the fan motor 1B and is discharged from an exhaust port 2B formed at the bottom of the main body 15.

Further, the main body cover 18 is provided with a claw 28 on the lower part that removably engages with the locking hole 27 of the main body 15, and a buckle 2S that similarly engages with the main body 15 on the upper part.

Problems to be Solved by the Invention In such a conventional vertical vacuum cleaner, the dust collection bag 20 is attached to the main body 15 by first fitting the mouth core 21 of the dust collection bag 20 with the bag holder 23. Rear, air intake port 22 on the inner wall side of the main body 15
At this time, since the main body 15 has a boat-shaped shape and the intake port 22 is provided at the bottom of the boat-shaped boat, the dust collection bag 20 is sometimes attached. I couldn't visually check the installation position, so I had to grope around to install it, which made it difficult to install, and I couldn't visually confirm whether it was completely installed or not.

In addition, when used many times, dirt adheres to the air intake port 22, and when the dust collection bag 20 is attached or removed, hands become dirty, and moreover, the main body 15 gets dirty.
Dust collection bag 20 is not that big, so it is difficult to reach inside.
There have been various problems in terms of hygiene and ease of use, such as difficulty in attaching and detaching.

An object of the present invention is to solve such problems and provide a vertical vacuum cleaner in which a dust collection bag can be easily attached and detached.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a main body with a built-in fan motor, etc., a main body cover that closes the main body opening, and an air intake port provided in a part of the back of the main body. and a dust collection bag removably built into a dust collection chamber formed by the main body and the main body cover, the intake port portion being a sloped surface portion having a concave shape at the front, and the air intake port being formed on the sloped surface portion. A dust collection bag mounting part is provided at the air intake port.

Function: As described above, in the present invention, the air inlet to which the dust collection bag is attached is formed so that the upper part of the slope is inclined toward the front of the main body. It is easy to operate.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2.

1 is the main body, and has wheels 2 for movement at the bottom.

3 is a suction fan motor built into the lower blade of the main body, 4 is a floor nozzle pivoted at the bottom of the main body 1, 5 is a handle formed to protrude above the main body 1, and 6 is a part for collecting dust inside the main body 1. a dust collection bag 7, a mouth core provided integrally with the dust collection bag 6; 8. is an intake port part, and a part of the back surface of the main body l is an inclined surface whose upper side is inclined toward the front side of the main body, and an intake port 9 is formed on this inclined surface.
It is formed by opening the.

Numeral 10 is a tight packing provided around the intake port 9, and 11 is a rib provided at both ends of the intake port portion 8, which is provided to guide the attachment of the mouth core 7 and to fix it. 12 is the subject l
The main body cover 13 that closes the front opening of the main body 1 has a hose that communicates the intake port 8 and the floor nozzle 4, and 14 has four parts. When the air intake port 8 is formed, it is formed on the outer side and upper side.

In the vacuum cleaner configured as described above, when attaching the dust collection bag 6, the mouth core 7 is inserted between the rib 11 provided on the intake port 8 and the surface of the intake port 8, and the tight packing 10 is used to attach the dust collection bag 6. Install with air tight.

Next, when removing the dust collection bag 6, it can be removed simply by pulling out the mouth core 7 from between the intake port 8 and the rib 11. Since the dust collection bag 6 is formed to be inclined toward the front opening side, it is possible to attach and detach the dust collection bag 6 while visually confirming the attachment and detachment, and it is possible to perform attachment and detachment operations easily and reliably. In addition, since the intake port 8 is formed with an inclined angle, when it receives the suction force F of the fan motor 3 during use, the force F1 acts accordingly, so even if the wick 7 is not properly attached, When the motor is driven, the mouth core 7 can be completely attached to the intake port 8 by the component force F. Furthermore, by forming the intake port 8 into an inclined surface, the recess 14 formed on the outer upper surface can be used as a handle when the main body is moved.

If the inclined upper end of the intake port is formed to protrude from the front opening surface of the main body toward the main body cover side, remove the main force bar and
When replacing the dust collection bag, the replacement work can be performed more easily.

Effects of the Invention As described above, the inlet port for attaching and detaching the dust collection bag is formed as a front curved slope with respect to the main body, so that the dust collection bag can be attached and detached easily and reliably. Moreover, even if the dust collection bag is not fully attached, the dust collection bag can be reliably attached using the force generated by the drive of the fan motor, and it has the advantage of being easy to use.
