BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an industrial vacuum cleaner provided with an elevating structure of a body,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an industrial vacuum cleaner equipped with a dust separating function, and more particularly, to a vacuum cleaner having a structure in which a body is vertically movable relative to a ground surface.

Generally, a drum type vacuum cleaner includes a head unit having an air blowing fan for sucking air, and a drum main body for sucking and filtering foreign substances such as dust and the like. Inside the drum body, a cylindrical filter is installed to filter out foreign matter such as dust that is sucked through a suction port that an operator holds by hand. The foreign matter filtered by the filter is accommodated in a dust collection box provided on the lower side of the filter. On the surface of the filter, fine dust is continuously attached as the cleaning operation progresses. As a result, the function of the filter is deteriorated. Conventionally, the fine dust adhering to the surface of the filter is shaken by manually applying an impact to the filter.

In this regard, a vacuum cleaner has been developed and used, which improves the convenience of operation by automating the function of removing fine dust adhered to the filter. An example of the vacuum cleaner equipped with the dust separating function of the filter is disclosed in Korean Patent Laid-Open Publication No. 2013-0115529.

The hopper 40 is detachably coupled to the lower portion of the drum body 30. The hopper 40 is provided with an inlet 42 for sucking foreign matter from the outside. The inflow port 42 may be coupled with an elongated inflow pipe (not shown) in the form of a flexible corrugated pipe.

The hopper 40 temporarily accommodates foreign matters filtered by the filter 35. The hopper 40 is provided with a foreign matter discharge port 44 which is opened downward and temporarily discharges the foreign substances contained therein.

The hopper 40 is installed on the frame 50 to be movable up and down. The frame (50) is supported on the ground by a wheel (52). The coupling structure of the frame 50 and the hopper 40 realizes the core effect of the present invention and will be described in detail below.

The frame (50) holds the hopper (40) in a position spaced upwardly from the ground. That is, the hopper 40 is coupled to the frame 50 such that the hopper 40 can be elevated in a direction perpendicular to the paper surface. The frame 50 may comprise a steel structure and includes a rod-like structure perpendicular to the ground.

A structure in which the hopper 40 moves up and down on the frame 50 will be described.

A lift member 60, a first link member 65 and a second link member 67 as a structure for coupling the hopper 40 and the frame 50 to each other.

The elevating member (60) is fixed to the hopper (40). The elevating member (60) moves integrally with the hopper (40). The elevating member 60 is slidably engaged with the frame 50.

The first link member 65 is disposed on the lower side of the elevating member 60. The first link member 65 is a bar-shaped structure. One end of the first link member (65) is rotatably coupled to the frame (50). On the other hand, the other end of the first link member 65 is rotatably coupled to a second link member 67 described later.

One end of the second link member 67 is rotatably coupled to the elevating member 60. The second link member 67 is rotatably coupled with the other end of the first link member 65 at a position spaced apart from the elevating member 60 by a predetermined distance. The second link member 67 functions to raise and lower the elevating member 60 in the direction perpendicular to the paper surface along the frame 50 with the first link member 65 leaning.

The elevating member 60, the first link member 65, and the second link member 67 are provided so as to be symmetrical with respect to each other. The other ends of the pair of second link members 67 are connected to each other to form an elevating handle 69. The elevating knob 69 may be formed in a straight line parallel to the ground. The second link member 67 can elevate the elevating member 60 with the first link member 65 as a lever by applying an external force to the elevating handle 69. [ Referring to FIG. 3, the coupling structure of the elevating member 60, the first link member 65, and the second link member 67 can be easily understood. 3 to 5 show the positions of the first link member 65 and the second link member 67 in the process of moving the elevation member 60 from the bottom dead center to the top dead center.

The elevating member (60) is provided with a position fixing hole (62). In addition, a coupling hole 54 is provided in the frame 50 at a position corresponding to the position fixing hole 62. The rod-like position fixing member 70 is inserted into the coupling hole 54 through the position fixing hole 62 in a state where the position fixing hole 62 and the coupling hole 54 are coaxially arranged. The elevating member 60 can be fixed at a specific position. The hopper 40 is fixed at a specific position by fixing the elevation member 60. [

On the other hand, the hopper 40 has a particle lift suppressing portion 46. The particle-rising suppressing portion 46 is a flange-shaped structure extending obliquely downward inward from the upper end of the hopper 40. The lower end of the particle-lift suppressing portion 46 forms a surface perpendicular to the paper surface. The particle rising suppressing portion 46 is disposed along the inner peripheral surface of the hopper 40. The particle lift-up suppressing portion 46 prevents particles of a large size and weight from being moved upward from foreign substances introduced into the hopper 40 from the outside. The particle uplifting suppressing part 46 serves to prevent the filter 35 from being damaged by preventing the foreign substance from colliding with the filter 35.

Meanwhile, the hopper 40 has a semi-automatic discharge cover 48. The semi-automatic discharge cover (48) is coupled to a foreign matter outlet of the hopper (40). The semi-automatic discharge cover (48) is rotatably coupled to the foreign matter discharge port (44). The semi-automatic discharge cover 48 is provided with a rotating shaft at an eccentric position, and a weight 49 is provided on the opposite side with respect to the rotation axis, so that the semi-automatic discharge cover 48 is temporarily opened only when foreign substances having a predetermined weight or more are accumulated in the hopper 40 . That is, the semi-automatic discharge cover 48 is opened by the weight of the foreign matter introduced into the hopper 40.

Meanwhile, the frame 50 includes a fixed shelf 80 and a movable shelf 85.

The fixed shelf 80 is fixed to the frame 50. The fixed shelf 80 is a structure for supporting the lower part of the flexible bag 200 for collecting foreign matter, which is coupled to the hopper 40.

The movable shelf 85 is a member slidably coupled to the fixed shelf 80. The movable shelf 85 is installed movably with respect to the fixed shelf 80 in a direction parallel to the paper surface. More specifically, the mobile shelf 85 can be linearly moved along the guide rail 82 provided on the fixed shelf 80. The moving shelf 85 is provided to easily separate the foreign matter collecting bag 200 from the hopper 40.

On the other hand, the frame 50 includes a reel mounting portion 56. The reel mounting portion 56 is disposed on the side surface of the frame 50. The reel mounting portion 56 may be fixed to the frame 50 by bolting or welding. The reel mounting portion 56 may be a fork-shaped structure having two windows, for example. As shown in FIG. 7, the reel mounting portion 56 may be provided with a reel 300 that winds and stores electric wires for supplying electric power to the blowing fan 26.

Hereinafter, the operation and effect of the industrial vacuum cleaner 10 having the above-described components will be described in detail.

First, the industrial vacuum cleaner 10 is moved from a storage room to a work space. In this process, the industrial vacuum cleaner 10 causes the elevating member 60 to be positioned at the bottom dead center as shown in FIG. As the elevating member 60 is positioned at the bottom dead center, the overall height of the industrial vacuum cleaner 10 is reduced and stability is secured.

Now, we explain the process of collecting foreign matter on the way to the workspace. An external force is applied to the elevating handle 69 so that the second link member 67 leans the first link member 65 from the bottom dead center position shown in Fig. 4 to the top dead center position shown in Fig. Whereby the hopper 40 rises. The distance between the lower end of the hopper 40 and the moving shelf 85 is increased so that the foreign matter collection bag 200 is installed therebetween and the entrance of the foreign matter collection bag 200 is inserted into the hopper 40 Fix by means such as band. Then, the blowing fan 26 is operated. As the blowing fan 26 is operated, air is sucked into the blowing fan 26 through the suction hole 22 and discharged to the outside through the exhausting hole (not shown). The pressure inside the drum body 30 is lowered. As a result, foreign matter such as dust in the work space flows into the hopper 40 through the inlet 42. The dust and air introduced into the hopper 40 rise while rotating. In this process, a particle-type foreign substance having a relatively large size and a heavy weight is caught by the particle-lift suppressing portion 46 and falls down to the bottom of the hopper 40. And fine foreign matters such as dust are raised and attached to the surface of the filter 35. As this process continues, dust accumulates on the surface of the filter 35. The striking member 37 is rotated by the dust separating motor 28 to strike the inner wall of the filter 35. As a result, dust adhering to the surface of the filter (35) drops down to the bottom of the hopper (40). The filter 35 is prevented from being damaged by the striking member 37 because the protective cover 36 is provided along the valley and the floor on the inner wall of the filter 35 in which the striking member 37 is contacted in this process. The effect of the present invention is remarkably suppressed. Unlike the conventional structure, since the protective cover 36 is continuously connected along the valley of the filter 35, the effect of protecting the filter 35 is doubled.

Now, the semi-automatic discharge cover 48 is opened by the weight of the foreign matter falling to the bottom of the hopper 40 and accumulated. As a result, the foreign matter temporarily accommodated in the hopper 40 is collected into the foreign matter collecting bag 200 coupled to the hopper 40. When a predetermined amount of foreign matter is collected in the foreign matter collection bag 200, the operation of the blower fan 26 is stopped and the foreign matter collection bag 200 is separated from the hopper 40. In this process, the foreign matter collection bag 200 can be easily separated from the hopper 40 by sliding the mobile shelf 85.

As described above, the industrial vacuum cleaner according to the present invention has a structure in which the elevating member can be elevated and lowered relative to the frame, so that it is possible to raise and lower the body as needed to facilitate the movement and facilitate the installation and separation of the foreign matter collecting bag . As a result, since the foreign matter can be continuously removed without separating the hopper and the drum main body, the efficiency of the operation is remarkably improved.

That is, in the industrial vacuum cleaner according to the present invention, since the hopper is movably installed to the frame, the drum body coupled with the hopper can be raised and lowered against the ground, so that the vacuum cleaner can use the vacuum cleaner in a raised state, It is possible to ensure the stability of operation of the vacuum cleaner by keeping the body in a lowered state when the vacuum cleaner is moved or stored without performing a vacuum cleaning operation. do.

Further, the elevating handle formed by connecting a pair of the second links as in the preferred embodiment of the present invention provides an effect of facilitating the workability of the operator in the process of raising and lowering the hopper.

Further, as in the preferred embodiment of the present invention, the position fixing hole and the engaging hole are combined with the rod-like position fixing member, thereby fixing the position of the hopper at a fixed height and preventing unexpected descent.

Also, in the case where the particulate build-up suppressing unit is provided as in the preferred embodiment of the present invention, lifespan of the filter can be extended by preventing the particulate matter having a large weight from reaching the filter.

Further, in the case where the hopper is provided with the semiautomatic discharge cover as in the preferred embodiment of the present invention, when the foreign matter of a certain weight is accumulated in the hopper, the semiautomatic discharge cover is automatically opened to allow foreign matter to be discharged easily, It is possible to remove the foreign matter from the hopper without separating the foreign matter from the hopper.

In addition, when the viewing window is provided as in the preferred embodiment of the present invention, since the surface of the filter can always be observed from the outside, it is possible to easily know the replacement time of the filter.

Further, in the case where the handle for separating and coupling is provided on the drum body as in the preferred embodiment of the present invention, in the process of detaching or reattaching the drum body from the hopper for replacement of the filter, So that the workability is improved.

Further, in the case where the reel mounting portion is provided as in the preferred embodiment of the present invention, since the electric wire for supplying electricity to the vacuum cleaner can be wound around the reel, the vacuum cleaner is advantageous in storing the vacuum cleaner.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications can be made by those skilled in the art within the technical scope of the present invention.
