Description

[Detailed Description of the Invention] The present invention provides a shelf or a top plate. This invention relates to an upright vacuum cleaner that has expanded cleaning functions by making it possible to clean even the corners of a room.

Upright-type vacuum cleaners generally have a floor nozzle attached to the bottom of the vacuum cleaner body with a built-in fan motor, etc., but due to its structure and weight, it is not suitable for use on shelves, ceilings, or corners of rooms. There was a problem that cleaning could not be done.

The present invention eliminates the above-mentioned conventional drawbacks and expands the cleaning function, and embodiments thereof will be described in detail below with reference to the accompanying drawings.

In Figs. 1 and 2, reference numeral 1 denotes a floor nozzle, and a rotary brush 2 for stirring up dust is built into the front part of the floor nozzle. Reference numeral 3 denotes a vacuum cleaner main body which is tiltably provided behind the floor nozzle 1, and a fan motor 4 for sucking dust is provided at the lower part of the vacuum cleaner main body 3, and a dust collection bag 5 is provided at the upper part. Reference numeral 6 denotes a shaft protruding from one end of the fan motor 4, and a power transmission belt 7 is stretched between the shaft 6 and the rotating brush 2. Reference numeral 8 denotes a joint hose, one end of which is connected to the rear of the rotating brush 2, and the other end connected to an intake port 9 provided at the rear of the upper part of the cleaner body 3. In addition, the air intake port 9 has a dust collection bag 5.
is connected to. 10 is a moving wheel; 11 is a back plate provided at the bottom of the floor nozzle 1; a suction port 12 is provided on the lower surface facing the rotating brush 2; 13 is a lid detachably attached to the front of the vacuum cleaner body 3 facing the dust collection bag 5; 14 is an operating handle disposed on the top of the vacuum cleaner body 3, and is made of a hollow pipe. has been done. Note that the lower end portion of the handle 14 communicates with the communication portion between the air intake port 9 and the dust collection bag 5. 15 is a valve provided at the branch point between the intake port 9 and the handle 14;
Selectively switch sides. 16 is an exhaust hole provided below the cleaner body 3.

In the above configuration, the operation will be explained next. In normal use, when the handle 14 is held and operated and the fan motor 4 is operated, the rotating brush 2 is rotated via the belt 7. The dust stirred up by the rotating brush 2 is collected by the suction force of the fan motor 4 from the connecting hose 8 through the intake port 9 into the dust collection bag 5, and only clean air is released from the exhaust port 16 to the outside. is released.

Next, we will explain how to clean shelves, ceilings, corners of rooms, etc. With the main body 3 of the vacuum cleaner in the standing position, operate the valve 15 to close the intake port 9 side and open the handle 14 side. do. After that, a separate attachment A is attached to the upper end of the handle 14.
Connect (hoses, extension pipes, various suction ports, etc.) as shown in Figure 3. For example, when cleaning a shelf, connect a hose and a shelf nozzle to the tip of the handle 14 and operate the fan motor 4. The suction force of the fan motor 4 will move dust from the shelf nozzle to the hose and inside the handle 14. The dust passes through and is collected in the dust collection bag 5.

FIG. 4 shows another embodiment, in which the upper end of the handle 14 is provided with a handle 17 that is detachable and seals the upper end of the handle 14. Note that the handle 15 can also be engaged and sealed with the intake port 9.

To explain the operation in this case, the joint hose 8 is removed from the intake port 9. and handle 17 to handle 1
4 and engage and hold it in the intake port 9. A separate attachment is attached to the upper end of the handle 14.

In this case, the ventilation path can be easily switched using the handle 17 of the handle 14 without providing a special opening/closing mechanism. It can also help prevent the loss of.

5 and 6 show still another embodiment, in which the lower surface of the handle 14 is closed and the dust collection bag 5 at the lower end is closed.
An opening 18 is formed on the side. In the case of intake from the handle 14, the handle 14 is pushed down into the ventilation passage. Then, the passage on the side of the intake port 9 is closed by the handle 14, and a ventilation passage is formed within the handle 14.

In the above embodiment, the ventilation passages were switched using the valve, the handle of the handle, and the handle, but other opening/closing mechanisms may also be used.In short, the ventilation passage on the floor nozzle side and the ventilation passage on the handle side can be selectively switched. All you have to do is switch.

As explained above, the present invention switches the intake system path so that air can also be taken in from the hollow handle, and by attaching an attachment to the handle, it is possible to achieve an improvement that was not possible with conventional upright vacuum cleaners. You can easily clean ceilings, shelves, etc., and the functions of the upright vacuum cleaner can be greatly expanded.
