Description

Description: TECHNICAL FIELD The present invention relates to an improvement of an electric vacuum cleaner having a blow-out portion having a length substantially the same as a length up to a suction portion by using exhaust gas of a cleaner body.

The conventional vacuum cleaner sucks the air in the suction pipe by the motor with the fan in the main body, reduces the atmospheric pressure, and sucks the dust at the tip of the suction pipe together with the air.Make the tip of the suction port close to the dust part. If you do not limit the amount of air in the surrounding area, the suction force will be weak, and if it is easily damaged, it will come close to you and tear the paper, or the closet or closet where the tip of the suction port does not enter, the gap on the back or bottom of the refrigerator, etc. Not suitable for use in. Further, in cleaning the inside of precision parts such as a television and a video deck, there is a risk that the tip of the suction port may be brought too close to the equipment to damage the internal parts.

Other than that, during cleaning, large pieces of paper, vinyl, etc. may be adsorbed, and dust may not be sucked in with the suction port blocked, but the paper pieces, vinyl, etc. may be removed by hand and cleaning may continue. In such a case, there has been a device in which a piece of paper or the like is removed by providing an air outlet hole around the opening of the suction port (for example, Japanese Utility Model Laid-Open No. 59-51556).

In the above case, conventionally, the cleaning method is changed by attaching another attachment corresponding to the cleaning location to the tip of the suction port. However, according to such a method, it is complicated to replace the attachment with a nozzle corresponding to the cleaning location, and a suction hole is provided around the opening of the suction opening to close the suction opening. With the method of removing dust particles such as paper pieces and vinyl that are exposed, it is possible to easily remove the paper pieces and vinyl that have blocked the suction port, but when cleaning a narrow space in a room or precision equipment, etc. Had the risk of. In addition, it is necessary to separately provide a blowing mechanism for removing dust, and there is a drawback in that a connection cord, an electric circuit, and the like for that are required.

The present invention has been made to solve the above-mentioned drawbacks, and includes a bellows-shaped suction pipe communicating with the suction side of the cleaner body, and a suction cylinder at the tip of the suction cylinder communicating with the suction pipe. A suction part having a fan with a larger diameter than that is provided, and a bellows-shaped blow-out pipe communicating with the blow-out side of the cleaner body, and a blow-out part provided at the tip of the blow-out tube communicating with the blow-out pipe,
(EN) An electric vacuum cleaner with an intake fan, which has a simple structure by allowing the tip of the blowout part to reach at least the vicinity of the suction part, and which can easily clean the details and any place. Is the purpose.

Hereinafter, the present invention will be described with reference to the illustrated embodiments.
FIG. 1 is an overall perspective view of an electric vacuum cleaner with an intake fan according to the present invention, and FIG. 2 is an enlarged perspective view of a suction section. In the figure, reference numeral 1 is a cleaner body which can be moved in any direction, and has a filter and suction means (not shown) built therein. Reference numeral 2 denotes a flexible bellows-shaped suction tube provided on the suction side of the cleaner body 1, and a suction tube 4 having a switch portion 3 is connected to the suction tube 2. A suction portion 6 having a suction port 5 is attached to the tip of the suction cylinder 4. A fan 7 having a diameter larger than that of the suction cylinder 4 is rotated by a motor 8 in the suction portion 6, sucks dust from the suction port 5, and stores the dust in the cleaner body 1. The fan 7 is not limited to the illustrated embodiment, and may be, for example, a propeller-shaped fan as long as it has a larger diameter than the suction cylinder 4. Reference numeral 9 is a protective net of the fan 7 attached to the front surface of the suction port 2, and 10 is a handle of the suction portion 6.

The suction cylinder 4 can be adjusted so as to expand and contract, and the suction portion 6 can be detached from the suction cylinder 4. Further, the bellows-shaped suction pipe 2 is also detachable from the cleaner body 1. Further, the activation of the cleaner main body 1 and the motor 7 in the suction portion 6 is centralized in the switch portion 3 and can be remotely performed at hand.

Reference numeral 11 denotes a bellows-shaped blow-out pipe provided on the blow-out side of the cleaner body 1, and a blow-out pipe 13 having a switch portion 12 is connected to the blow-out pipe 11. A blowout portion 14 having a blowout port 15 is attached to the tip of the blowout tube 13. The blowout port 15 has a thinned top end portion for increasing the blowing force. Further, the tip of the blow-out portion 14 is provided at least in a length substantially the same as the length of the suction portion 6, and the length thereof is adjustable. This blow pipe 11
Is provided on the outlet side of the cleaner body 1, but when used as a normal cleaner, if the outlet pipe 11 is removed, the air sucked together with the dust will be sterilized and then exhausted through the filter. It has become so.
Since the pressure of the exhausted air is used as the blowing pressure to the blow-out pipe 11, no special equipment or electric circuit for blowing out is required.

When using the vacuum cleaner with the intake fan configured as described above, when the power of the switch unit 3 is input,
The suction means built in the cleaner body 1 is activated, the motor 8 in the suction portion 6 is also activated at the same time, and the fan 7 rotates. The suction port 5 of the suction unit 6 is directed to the cleaning location, and strong suction is performed from the suction port 5 by the suction means and the fan 7, so that dust can be sucked. The sucked dust is housed in the cleaner body 1 and clean air is exhausted through the sterilization filter.

At this time, by holding the blow-out tube 13 and directing the blow-out port 15 of the blow-out portion 14 toward a narrow place in a room or a cleaning place such as precision equipment, the dust pressure at the cleaning place is expelled by the exhaust pressure from the cleaner body 1. You can get up and up. Then, the ejected dust is sucked again by the suction portion 6 having a large diameter to clean the dust. The switch unit 12 may be configured to interlock with the switch unit 3 of the suction cylinder 4, or may be an independent circuit.

As described above, according to the present invention, the bellows-shaped suction pipe 2 that interlocks with the suction side of the cleaner body 1 and the tip of the suction pipe 4 that communicates with the suction pipe 2 have a larger diameter than the suction pipe 4. Na fan 7
Is provided with a suction part 6 having a bellows, and a blowing pipe 11 communicating with the blowing side of the cleaner body 1, and a blowing part 14 provided at the tip of a blowing cylinder 13 communicating with the blowing pipe 11. Is configured to reach at least the vicinity of the suction portion 6.

Therefore, you can use pressured air to enter freely in any narrow place or winding place to expel dust and create a large amount of air flow using a fan with a larger diameter than the suction port of a conventional vacuum cleaner to suck. However, unlike conventional vacuum cleaners, it is not a vacuum type, so it does not need to be brought too close to dust, and it can be used in any gaps to prevent damage to cleaning points and precision equipment. Further, since the air having a pressure to be blown uses the air pressure exhausted by suction, a new electric circuit is not required separately, so that the structure is simple.
