Description

A VACUUM CLEANER WITH SUCTION & BLOWING

The present invention relates to a vacuum cleaner, and in detail, the suction device installed in the rotational direction of the motor and the air passage of the vacuum cleaner allows the user to select the intake of the air and the discharge of the air, that is, the blowing by operating the switch. It is to compensate for the shortcomings which did not get satisfactory cleaning effect by itself, so as to increase the efficiency of dust cleaning.

Conventional vacuum cleaners can only rotate the AC or DC motor in one direction to suck the dust into the dust bag installed in the dust storage inside the vacuum cleaner. Therefore, in a place where it is difficult to suck the dust, only the suction action is satisfactory. There was a disadvantage that can not be effective.

That is, the conventional vacuum cleaner could only rotate the AC or DC motor in one direction and suck the dust into the dust bag installed in the dust storage inside the vacuum cleaner. Therefore, the suction action may be satisfactory in a place where it is difficult to suck the dust. There was a disadvantage that can not achieve a sufficient cleaning effect.

In other words, the conventional vacuum cleaner unilaterally sucks air and sucks the dust into the dust storage, so it is satisfactory to suck in the cramped place where the inlet end of the vacuum cleaner cannot enter or to the end of the inlet. There were some places that could not be cleaned. In these places, a strong wind blows or blows away the dust, or once the dust obscured by the obstacle is blown and re-inhaled, the cleaning effect can be improved. The vacuum cleaner was unable to perform this function, so it was inconvenient to remove dust and other debris.

Meanwhile, Korean Utility Model Publication No. 94-14549 discloses a technology in which a blower is provided in the vacuum cleaner to give a blower function to the vacuum cleaner, which separates the blowing force generated at the rear of the blower fan during the suction action. There was a disadvantage in that it is inconvenient to use.

In addition, Korean Patent Publication No. 97-167 discloses a technique for an air-circulating vacuum cleaner, which has a drawback in that the cleaning efficiency is halved due to the blowing operation at the same time as the intake of dust. The poems are known from Pub. No. 95-24732, Pub. No. 97-32642 and the like.

The present invention has been made to solve the above disadvantages of the conventional vacuum cleaner, the object of the present invention is to select the suction and blowing function by allowing the suction and blowing of dust selectively with one vacuum cleaner according to the place It is to make dust removal efficient.

In order to achieve the above object, the present invention provides a vacuum cleaner configured to suck external dust into the dust storage through the suction port of the air passage tube by the suction force generated in the blower fan.

A forward and reverse motor capable of forward and reverse rotation of the blowing fan;

5 and 6 show an example of the second opening and closing device 8, which shows a closed state and an open state, respectively. The second opening and closing device 8 has a power supply to the electromagnet coil 17. In the non-applied state, the opening and closing plate 19 made of magnetic material blocks the second opening and closing part 6 as shown in FIG. 5, and when the power is applied, the opening and closing plate 19 sticks toward the electromagnet coil 17. The second opening and closing part 6 is to be in an open state, and the opening and closing device in the present invention may use various methods as well as the same manner as in FIGS. 5 and 6.

The first opening and closing device 7 may also be used in a similar manner to the second opening and closing device 8, and if there is a difference, the opening and closing plate 19 is in communication with the air passage pipe 15 by supply of power. One of the reservoirs 9 and the air blower 2a is opened and the other is blocked.

The operation of the vacuum cleaner according to the present invention configured as described above will be described by dividing into suction and blowing operations.

First, in order to clean and suck dust like a conventional vacuum cleaner, when the changeover switch 16 shown in FIGS. 7 and 8 is switched from the off state B to the terminal A, the motor 1 While the power is supplied and rotates in one direction, power is also applied to the first opening and closing device 7 so that the opening and closing plate blocks the air passage 2a and the dust storage 9 is opened, and the second opening and closing device 8 is also provided. Since the power is applied to the open state, the air sucked with the dust from the suction port 3 is sucked into the dust storage unit 9 through the first opening / closing device 7 and the dust in the air sucked into the dust bag (not shown). After being stored, the air is discharged to the outlet 4 through the second opening and closing device 8 and the suction blowing control tube 2, which are opened via the dust filter 10. No different.

Next, in places where suction cleaning is difficult and ventilation is required, the changeover switch 16 is positioned to the C terminal in FIGS. 7 and 8, and the motor 1 is different from the above as shown in FIG. Since the air rotates in the opposite direction, the air is sucked in through the discharge port 4, and in contrast to the suction, the first opening / closing device 7 is turned off so that the air passage 2a is open and dusty. The reservoir 9 is in a blocked state, and the second opening and closing device 8 is also shut off by shutting off the power, so that the air generated in the blower fan passes through the air passage 2a through the air blower 2a in the suction blower control tube 2. It is discharged to the suction port 3 of the tip of the pipe 15 to blow dust or other foreign matter in a place where suction cleaning is difficult.

The cleaner user can properly clean the suction switch or the blower by properly adjusting the changeover switch 16. Therefore, the vacuum cleaner can not be used only in the suction inlet tip of the vacuum cleaner, which can only be exerted in the conventional suction function, or in a place where the cleaning function is not performed properly only by the suction function. By operating the selector switch 16, it blows off the dust and the like, blows off the dust, and then switches to suction to suck the dust in the air back into the cleaner.

As described above, the present invention controls the opening and closing of the blower fan and the opening and closing device installed in the air passage pipe by the operation of the switching switch. You can use it to make the cleaning more convenient and to increase the cleaning effect.
