Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cyclone type wet electric vacuum cleaner which adds water to a cyclone dust collecting system to improve dust collecting efficiency and prevent scattering of collected dust.

[0002]

2. Description of the Related Art Generally, there are two types of vacuum cleaners, a wet vacuum cleaner and a dry vacuum cleaner. In a conventional wet vacuum cleaner, as shown in FIG. 6, the electric vacuum cleaner disclosed in Japanese Patent Laid-Open No. 7-163498 is disclosed. An example of such a vacuum cleaner is one in which water 2 contained in a water pan 1 is sucked through air 3 containing sucked dust. In the figure, 4 is a suction motor, 5 is clean air, and 6 is dust-containing bubbles.

On the other hand, a cyclone type vacuum cleaner classified as a dry type vacuum cleaner sends air containing dust in a circumferential tangential direction to a cylindrical cyclone dust collecting chamber, and centrifugal force causes air and solids to become air. The one that separates and removes the dust.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
In the structure of the wet vacuum cleaner described in Japanese Patent No. 498,
Since the air 3 containing dust is passed through the water 2, the pressure loss increases and the suction capacity decreases. Further, when the air 3 flows into the water 2, dust-containing bubbles 6 containing fine dust are generated, and when the dust-containing bubbles 6 are broken, the fine dust flows out to the outside. There is a problem that fine dust is contained in the dust-containing bubbles 6 even if a means for making the fine 6 fine and increasing the contact area with the fine dust is used. In addition, when disposing of waste, the user has to throw away a large amount of dirty water, which is a problem in the waste disposal method.

On the other hand, in the structure of the cyclone type vacuum cleaner, it is necessary to increase the diameter of the cylinder in the cyclone dust collecting chamber in order to obtain the dust collecting volume. This increases the particle size of the particles that can be collected by the cyclone, which leads to the outflow of fine dust.

Further, as a means for collecting fine dust by the cyclone method, there is a method of reducing the diameter of the cylinder of the cyclone dust collecting chamber. However, there has been a problem in that the pressure loss increases and the dust collection volume decreases by reducing the cylindrical diameter of the cyclone dust collecting chamber.

As another means for collecting fine dust, a cyclone type wet electric vacuum cleaner has been proposed in which fine water droplets are sprayed by a spray nozzle, or steam is generated by a heat source to add steam to the dust. . More specifically, the cyclone type wet electric vacuum cleaner using the spray nozzle is for simply injecting atomized water in the intake pipe connecting the suction port of the air containing dust and the cyclone dust collecting chamber,
The cyclone wet vacuum cleaner that generates water vapor simply lowers the water vapor from above the cyclone dust collecting chamber to below.

However, in a cyclone type wet electric vacuum cleaner using a spray nozzle, a separate power unit such as a pump is required to pump the water stored in the tank, and the atomization unit itself becomes large, which is a problem. There is a problem that the spray nozzle that creates water drops is expensive.

Further, the cyclone type wet electric vacuum cleaner method for generating water vapor has a problem that a heat source for evaporating water is required and power consumption increases.

Furthermore, none of the above-mentioned two cyclone-type wet electric vacuum cleaners is sufficiently satisfactory as a dust collecting effect.

The present invention efficiently collects fine dust by causing atomized water to spirally descend from above the dust collection chamber,
It is an object of the present invention to provide a cyclone-type wet electric vacuum cleaner capable of further improving the dust collecting effect.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a cyclone-type wet electric vacuum cleaner according to the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

FIG. 1 is a horizontal sectional view of a cyclone type wet electric vacuum cleaner according to the present embodiment, FIG. 2 is a vertical sectional view of an atomizing section shown in FIG. 1, and FIG. 3 is a cyclone shown in FIG. FIG. 4 is a perspective view of the dust collecting chamber, FIG. 4 is a vertical sectional view of the cyclone dust collecting chamber shown in FIG. 1, and FIG. 5 is a transverse sectional view of the cyclone dust collecting chamber shown in FIG.

As shown in FIG. 1, the cyclone type wet electric vacuum cleaner according to the present embodiment has a vacuum cleaner body 11 in which
An intake pipe 13 that guides air 12 containing dust (hereinafter referred to as “dust-containing air”) sucked from an intake port (not shown) into the cleaner body 11, and an intake pipe 13 that communicates with the intake pipe 13. Cyclone dust collection chamber 14 for supplementing dust contained in dust air 12
An exhaust pipe 16 for exhausting the clean air 15 from which dust has been removed in the cyclone dust collecting chamber 14, a water supply tank 17, an ultrasonic vibrator (ultrasonic vibrating means) 18, an atomization tower ( (Atomization chamber) 19, atomization guide pipe 20 for communicating the atomization tower 19 and the cyclone dust collection chamber 14, water leveler 2
It is composed of an atomizing unit consisting of 1. In the figure, 22 is a suction motor for sucking air and generating an air flow.

As shown in FIG. 2, the atomizing unit supplies the water 23 stored in the water supply tank 17 onto the ultrasonic vibrator 18, and the water 23 is generated by the ultrasonic vibration of the ultrasonic vibrator 18. It is atomized by blowing up. When the water 23 on the ultrasonic transducer 18 is atomized and reduced, the water level 17 causes the water level 17 to decrease the amount of the water 23.
More water 23 is supplied.

The atomized water 24 that has been atomized is stored in the atomization tower 19 and the negative pressure in the cyclone dust collection chamber 14 from the atomization guide pipe 20, specifically, the suction pressure of the suction motor 22 is changed. It is used to flow into the cyclone dust collecting chamber 14.

Cyclone dust collecting chamber 14 from the intake pipe 13
As shown in FIGS. 3 and 4, the dust-containing air 12 flowing into the chamber is introduced in the circumferential tangential direction from the upper portion of the cyclone dust collecting chamber 14 having a cylindrical shape so as to give a centrifugal force to the air flow.
That is, the end portion of the intake pipe 13 on the side of the cyclone dust collecting chamber is swirled in the circumferential direction along the inner wall of the cyclone dust collecting chamber 14, whereby the dust-containing air 12 flows from the intake pipe 13 into the cyclone dust collecting chamber 14. Intake port that guides the cyclone dust collection chamber 1
Therefore, the dust-containing air 12 is introduced in the circumferential tangential direction. As a result, the swirling airflow 25 is generated.

As shown in FIGS. 3 and 4, the atomization guide tube 20 has a water inlet at the end of the cyclone dust collecting chamber on the upper side of the cyclone dust collecting chamber 14 and the exhaust pipe 17. It is arranged above the end of the cyclone dust collecting chamber (specifically, the exhaust port of the clean air from the cyclone dust collecting chamber 14). With this structure, the swirling airflow 2
The dust can be covered with the atomized water 24 before 5 reaches the exhaust port, and it is possible to prevent the dust from flowing out of the exhaust port before separation due to the short-circuit airflow.

Further, the atomized water 24 is stored in the cyclone dust collecting chamber 1
It is introduced in the same direction as the above-mentioned dust-containing air 12 in the circumferential tangential direction. In this way, by introducing the atomized water 24 and the dust-containing air 12 in the same circumferential tangential direction, the dust-containing air 12
Atomized water 24 and dust-containing air 1 without disturbing the swirling airflow 25 of
Can be mixed with 2.

With such a configuration, as shown in FIG. 5, the dust-containing air 12 flowing in from the intake port 14a is introduced in the circumferential tangential direction of the cyclone dust collecting chamber 14 and flows in the same circumferential tangential direction. Mix with the atomized water 24. As a result, the atomized water 24 is adsorbed on the dust, and the adsorbate 26 has an apparently larger volume and weight than the dust alone. Further, since water is adsorbed on the surface of the dust, cohesiveness with other dust is enhanced.

Therefore, the centrifugal force in the cyclone dust collecting chamber 14 becomes large, and fine dust which cannot be removed by the conventional cyclone type wet electric vacuum cleaner because of its small volume and weight can be removed, and clean air can be removed. 15 flows out from the exhaust pipe 16 through the exhaust port. Further, the atomized water 24 not adsorbed on the dust adheres to the inner wall of the cyclone dust collecting chamber 14 or spirally turns and drops. Therefore, the atomized water 2
The dust that has not been adsorbed can be adsorbed to the atomized water 24 on the inner wall. Further, since the dust and dirt collected on the bottom surface of the cyclone dust collecting chamber 14 contain water, it is possible to prevent the dust from re-scattering during the dust collection and prevent the dust from flowing out due to the re-scattering.

In addition, it is necessary to use a large pump for pumping water in a water storage tank such as a conventional cyclone type wet electric vacuum cleaner, an expensive spray nozzle, or a heat source that requires large power consumption to evaporate water. Since microdroplets can be created without using the atomization means, it is possible to reduce the size, power consumption and cost of the cyclone type wet electric vacuum cleaner using the atomizing means.

Naturally, it is possible to omit the waste water treatment at the time of dust disposal, which has been a problem in the conventional wet electric vacuum cleaner, and since dust-containing air is not passed through the water, the pressure loss is small, and Can use less water.
Since no filter is used for the conventional dry electric vacuum cleaner, there is no concern that the suction performance will be deteriorated due to clogging, and dust can be prevented from rising.

In the above-described embodiment, the dust-containing air 12 and the atomized water 24 are introduced in the circumferential tangential direction of the cyclone dust collecting chamber 14 in order to swirl them spirally. A configuration may be employed in which each of them is spirally turned by providing the generating means.

[0035]

It is possible to collect fine dust that cannot be captured by the conventional cyclone wet vacuum cleaner. Therefore, the dust collection effect can be improved.

Further, in the invention as set forth in claim 2, the atomizing section comprises an ultrasonic vibrating means for atomizing water, and an atomizing chamber in which the ultrasonic vibrating means is installed and water is stored. Since it is configured to include a large water droplet in a water tank as in the conventional pump and an expensive spray nozzle, or a heat source that requires large power consumption to evaporate water Can be produced. Therefore, in addition to the above effects, the cyclone-type wet electric vacuum cleaner can be downsized, the power consumption can be reduced, and the cost can be reduced.

Furthermore, the invention according to claim 3 is an atomizing section comprising ultrasonic vibrating means for atomizing water, and an atomizing chamber for storing the water while the ultrasonic vibrating means is installed inside. And the atomization guide pipe for supplying the atomized water atomized in the atomization section to the cyclone dust collecting chamber, so that a large shape for pumping the water in the water storage tank as in the conventional case is large. Microdroplets can be created without the use of pumps and expensive spray nozzles, or heat sources that require high power consumption to evaporate water. Therefore, the cyclone-type wet electric vacuum cleaner can be downsized, the power consumption can be reduced, and the cost can be reduced.

In addition, in the invention of claim 4, since the water supply port of the atomized water in the cyclone dust collecting chamber is installed above the exhaust port for discharging clean air from the cyclone dust collecting chamber, The dust can be covered with the atomized water before the air including the air reaches the exhaust port, and the dust is prevented from flowing out due to the short-circuit airflow.

In addition, the invention according to claim 5 collects the water supply port of the atomized water so that the swirl airflow of the atomized water and the swirl airflow of air containing dust are in the same direction in the cyclone dust collecting chamber. Since it is arranged in the tangential direction of the inner wall of the dust chamber, the dust and the atomized water can be mixed without disturbing the flow of the swirling air flow of the dust-containing air. Therefore, the dust and the air can be efficiently separated by the swirling airflow and the dust can be captured by the atomized water, and the dust capturing effect can be further improved.
