However, in the above-mentioned conventional air cleaner, although the intake port 106 is widely provided and dust and gas components floating in the air can be sucked, it will settle in the air and be deposited on the surface to be cleaned. As for the dust, the pressure for suction cannot be generated and cannot be the target of suction. Further, although the vacuum cleaner generates a strong suction force by using the negative pressure of the electric blower, it is not suitable for inhaling the dust in the surroundings when it is stationary and it is not suitable for inhaling the dust that sinks after being installed for a long time. Further, generally, the electric motor used for the vacuum cleaner is a high-speed rotating commutator motor and is not suitable for long-term operation in terms of life. Therefore, it reduces the amount of dust such as so-called cotton dust that floats in the air and sinks to accumulate on the surface to be cleaned.
There has been a problem that equipment for improving indoor cleanliness cannot be easily realized in a general home.

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a sectional view of a main body of a cleaning machine according to a first embodiment of the present invention, and FIG. 2 is a perspective view of the cleaning machine.

In FIGS. 1 and 2, reference numeral 1 is a cleaner body (hereinafter referred to as body 1), and 18 is a synchronous motor 2 and a fan 3.
And a dust suction port 5 provided in the vicinity of the surface to be cleaned 19 of the front panel 4 which is an outer surface of the main body 1 which is detachably attached to the main body 1 and which is formed of a transparent member. The wind sucked from the dust suction port 5 is filtered by the dust collection filter 6 provided on the upstream side of the suction device 18 and blown out from the exhaust port 7. The dust suction port 5 has a height from the surface to be cleaned 19 of 10 mm or less and is formed below the center of the front panel 4 so as to be close to the surface to be cleaned 19, and the opening area is the ventilation area of the dust collecting filter 6. Is about 5%. In addition, the exhaust port 7 is provided with a louver so that the exhausted air is directed obliquely upward and forward. Reference numeral 8 denotes a dust collecting space formed between the dust collecting filter 6 and the front panel 4.

Next, the operation and action will be described. Light dust such as so-called cotton dust on the surface to be cleaned 19 is sucked into the inside of the main body 1 of the cleaner through the dust suction port 5 by the suction air generated by the suction device 18. It is adsorbed on the front surface of the dust filter 6.
By narrowing the area of the dust suction port 5, even if the fan 3 has a so-called air volume type configuration, the pressure is somewhat increased, and the wind velocity passing through the dust suction port 5 is increased as compared with the wind velocity passing through the dust collecting filter 6. Thus, the effect of attracting dust on the surface to be cleaned 19 is enhanced. If the opening area of the dust suction port 5 is set to 5% of the ventilation area of the dust collecting filter 6, the wind speed can be increased about 20 times, and the dust collecting effect of the dust collecting filter 6 can be increased while increasing the dust collecting efficiency. I am raising. By concentrating the dust suction ports 5 in the vicinity of the surface to be cleaned 19, a flow of air along the surface to be cleaned 19 can be performed, and dust on the surface to be cleaned 19 can be easily attracted and sucked up. If the dust suction port 5 is separated from the surface to be cleaned and the area is large, the amount of intake air from the space increases, but the surface to be cleaned 1
The wind flow along 9 rapidly weakens. If the dust on the surface to be cleaned 19 is swept to the vicinity of the dust suction port 5 of the main body 1 with a mop or the like, it is easy to suck it up into the main body 1. Also, the exhaust port 7
Since it is diagonally above, the blowing air is reflected and circulated on the ceiling 20 and the wall 21, pushes dust on the surface to be cleaned 19, and has a synergistic effect with the intake air to increase the force of drawing toward the dust suction port 5 and thus to a wider area. It is possible to inhale the garbage.

Further, since the front panel 4 is made of a transparent member, the amount of dust adhering to the dust collecting filter 6 can be easily determined, so that the maintenance time can be known. For maintenance, since the front panel 4 is detachably attached to the main body 1, it is sufficient to suck dust adhering to the dust collecting filter 6 with a vacuum cleaner or the like with the front panel 4 removed. In particular, instead of mainly inhaling airborne fine dust like air fresh air, it sinks down to the surface to be cleaned or inhales light dust such as blown cotton dust. It is effective to provide a large capacity and suck it with a vacuum cleaner.

(Second Embodiment) FIG. 3 is a perspective view showing a cleaning machine according to a second embodiment of the present invention.

The second embodiment differs from the first embodiment in that the front panel is replaced with 4a and the dust suction port is replaced with 5 to 5a.

Next, the operation and action will be described. By detaching the front panel, the front panel can be replaced (4 and 4a).
Can be used as a substitute for clean air.

(Embodiment 3) FIG. 4 is a sectional view showing a cleaning machine according to a third embodiment of the present invention. The third embodiment differs from the first embodiment (or the second embodiment) in that the dust suction port 5 provided in the front panel 4 projects from the dust collection space 8 formed by the front panel 4 and the dust collection filter 6 to be cleaned 19 It was installed close to.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

Next, the operation and action will be described. Since the dust suction port 5 projects from the dust collecting space 8, the surface to be cleaned 19 is
Therefore, the dust suction port 9 can be provided closer to each other, and the efficiency of the flow of the air sucked along the surface to be cleaned 19 on the front surface of the main body 1 can be further improved. Further, it is easy to guide the dust that has been attracted into the dust collection space 8 by the effect like dust while narrowing the opening area of the dust suction port 5 and suck it up.

(Embodiment 4) FIG. 5 is a sectional view showing a cleaning machine according to a fourth embodiment of the present invention. The fourth embodiment differs from the first embodiment (or the second embodiment) in that the dust collecting filter 6 built in the cleaner body 10 faces the surface to be cleaned 19, and the dust suction port 12 provided in the bottom panel 11 collects dust. It faces the filter 6 and the surface 19 to be cleaned. The bottom panel 11 has a surface 19 to be cleaned.
And the gap between them is approximately 10 mm or less. The opening area of the dust suction port 12 is set smaller than the ventilation area of the dust collection filter 6 and the ventilation area of the dust collection space 14. Exhaust gas is blown from the exhaust port 13 to the outer periphery of the main body 10. The dust collecting space 14 formed between the bottom panel 11 and the dust collecting filter 6 serves as a tray when dust adsorbed on the surface of the dust collecting filter 6 drops when suction is stopped. Reference numeral 15 is a collar that suppresses the diffusion of the flow of air to the dust suction port 12.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

Next, the operation and action will be described. The dust suction port 12
Is opposed to the surface to be cleaned 19, dust from the entire periphery of the main body 1 can be sucked, and the area of the dust suction port 12 becomes the full-time area of the dust collection filter 6 and the ventilation area of the dust collection space 14. Since it is sufficiently small in comparison, the suction pressure once dust that has been sucked into the dust collection space 14 falls onto the bottom panel 11,
Since the dust suction port 12 has a stronger wind speed, the dust collection filter 6 is again used.
The force of sucking in dust from the surrounding area becomes stronger than that of being absorbed by.

(Embodiment 5) FIG. 6 is a partial sectional view showing a cleaning machine according to a fifth embodiment of the present invention. The fifth embodiment is different from the first embodiment (or the second embodiment) in that a lever 16 is provided on the side surface of the cleaner body 1, and the lever 16 is interlocked with the vertical operation of the lever 16.
Dust remover 1 that moves up and down along with the built-in dust collection filter 6
7 is provided.

The same reference numerals as those in the first embodiment have the same structure, and the description thereof will be omitted.

Next, the operation and action will be described. The lever 16
By operating up and down, dust (cotton dust etc.) adsorbed by the dust collection filter 6 due to long-term operation and use can be pushed up and down on the surface of the dust collection filter 6 and the central part of the dust collection filter 6 can be moved. It can be reused. If the dust collection space 8 cannot be made large because the dust suction port 5 is on the surface to be cleaned, the dust remover 17 is always provided with the dust collection filter 6
It is effective to place it at the lower end of the above, and the folding direction of the peaks and valleys of the dust collecting filter 6 may be set to the horizontal direction and the lever may be moved left and right.

In each of the above-mentioned embodiments, the suction machine is a synchronous motor and a sirocco type fan, but it may be a brushless motor, a turbo fan or the like.

As described above, the cleaning machine according to claim 1 of the present invention comprises a suction device for sucking dust and a main body having a dust collecting filter for collecting dust on the upstream side of the suction device. , With the main body installed, a dust suction port is provided only on the outer surface of the main body in the vicinity of the surface to be cleaned, so that the diffusion of the air flow sucked into the dust suction port is suppressed and the dust is sucked into the dust suction port along the surface to be cleaned Since the airflow can be efficiently used and the dust accumulated on the surface to be cleaned can be easily sucked, it is possible to suppress the accumulation of dust on the surface to be cleaned around the cleaning machine. In addition, if dust or the like is swept up to the vicinity of the dust suction port of the main body with a mop or the like, there is an effect that it can be easily sucked into the main body.

Further, in the cleaning machine according to the second aspect, a dust collecting filter is built in so as to face the front surface of the main body, and a suction machine is built in so as to face the dust collecting filter, and the dust suction port is located at the center of the front surface of the main body. Since it is provided on the lower side, the pressure of the sucked air can be raised to more than twice the pressure on the surface of the dust collection filter, and the dust collection filter close to the dust inlet where the collected dust is concentrated. When the air permeability of the lower part is lower than that of the side part, the upper part of the dust collecting filter is left as a part of the filter that bypasses and further inhales dust, so the entire surface of the filter is effectively used and the suction force is increased. There is an effect that can be sustained.

In the cleaning machine according to the third aspect, the dust suction port is formed so as to project forward from the space formed between the front shell and the dust collecting filter, and the dust suction port is very close to the surface to be cleaned. Since the air flowing into the dust suction port more efficiently follows the surface to be cleaned at the front surface of the dust suction port, the dust contacting the surface to be cleaned can be more effectively sucked.

According to a fourth aspect of the present invention, in the cleaning machine, a dust collecting filter is provided so as to face the bottom surface of the main body, a suction device is provided so as to face the dust collecting filter, and a dust suction port is provided on the bottom surface of the main body. Therefore, there is an effect that the dust suction effect can be exhibited in all directions around the main body. Further, since the dust suction port is hard to see, there is an effect that the decorativeness can be improved in the appearance.

Further, in the cleaning device according to the fifth aspect, the opening area of the dust suction port is 5% or less of the area of the dust collecting filter, and the wind speed at the dust suction port is 2 more than the wind speed of the air passing through the filter.
There is an effect that the suction pressure can be increased to about 0 times, the suction pressure can be increased, and a decrease in suction force can be suppressed until more dust is suctioned and adhered over the front surface of the dust collection filter.

A cleaning machine according to a sixth aspect of the present invention has a blowout port through which exhaust air emitted from the suction machine is discharged from the main body to the atmosphere, and the exhaust air is directed toward the upper surface of the main body or toward the front side of the upper surface of the main body. The air outlet is formed so as to be discharged toward the exhaust air, and the exhaust air blown out becomes a circulating air current and floats, and dust and cotton dust are advancing together with the intake air to the dust inlet. There is an effect that more suction can be performed over a wider area.

In the cleaning machine according to claim 7 of the present invention, the opening area of the dust suction port can be selectively changed, and the function close to that of the air cleaner and the function as the cleaning machine can be selectively utilized. There is an effect that can be.

In the cleaning machine according to claim 8 of the present invention, the whole or a part of the outer peripheral surface of the main body having the dust suction port is detachable, and the dust that has been sucked and adhered to the dust collecting filter is removed by the front surface. It is possible to easily perform suction maintenance with a vacuum cleaner or the like, and to replace the dust collecting filter. In particular, the clean air does not have much suction effect with a vacuum cleaner because it mainly sucks fine airborne dust and gas components in the air, but even if the cleaner is dust, it will settle in the air or the surface to be cleaned. Since the so-called cotton dust that is blown away is mainly, the maintenance effect by suction with a vacuum cleaner is high.

In the cleaning machine according to claim 9 of the present invention, the whole or a part of the outer peripheral surface of the main body having the dust suction port is formed of a transparent member, and the degree of adhesion of the dust to the dust collecting filter can be easily understood. The effect is that you can easily know the timing and the effect of the equipment, and it will be easier to handle.

A cleaning machine according to a tenth aspect of the present invention is provided with means for removing dust adhering to the surface of the dust collecting filter, or for compressing after removing the dust collecting filter. By collecting dust temporarily, there is an effect that it is possible to further secure the area of the dust collecting filter that can be sucked and collected. In this case as well, the effect of being able to draw the cotton dust is great. In general, a brushless motor such as an induction machine or a transistor motor, which can continuously operate with a low input for a long time and a relatively small noise, is suitable as an electric motor that constitutes a suction machine, as compared with a general vacuum cleaner. Further, the filter does not necessarily have to be accompanied by a deodorizing filter like an air purifier, and may be one having an aroma effect such as impregnating the filter.
