Hereinafter, preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the embodiments described herein and may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosed content will be thorough and complete, and the spirit of the present invention will be sufficiently conveyed to those skilled in the art. Like reference numbers indicate like elements throughout the specification.

1 is a combined perspective view of an air cleaning blowing device 1000 according to an embodiment of the present invention, and FIG. 2 is an exploded perspective view of the air cleaning blowing device 1000.

1 and 2, the air cleaning blower 1000 includes a filter 600 to filter foreign substances in the air and to provide filtered air to the filtering unit 500 and the filtering unit 500. It is detachably connected and includes a blowing unit 100 for blowing air by providing a negative pressure to the filtered air.

That is, in order to provide a simple blowing function or an air cleaning function, the air cleaning blowing device 1000 according to the present invention is mounted on the blowing unit 100 that provides a blowing function and optionally the blowing unit 100 to provide an air cleaning function. It may be configured to include a filtering unit 500 for providing.

In addition, as shown in FIG. 1 , the blower unit 100 may be configured in the form of a so-called 'box-type fan', and the filtering unit 500 may be stacked or molded together with the blower unit 100 to be closely fastened. It may be configured in a rectangular box shape so that it can be, but is not limited thereto.

That is, the thickness of each of the filtering unit housing 510 and the blowing unit housing 110 may be smaller than the respective width or height, and the filtering unit and the blowing unit may be mounted together.

Therefore, in a season when the need for the air cleaning function is relatively low, for example, the summer season, the filtering unit 500 is removed and the blower unit 100 is used for a purpose such as an electric fan, and the need for the air cleaning function is relatively high. During the season, for example, the winter season, a filtering unit 500 may be further added to the blowing unit 100 to be used as an air purifier. Of course, it may be used with the filtering unit 500 attached to the blowing unit 100 irrespective of seasonal changes.

Therefore, the air cleaning blowing device 1000 includes the filtering unit 500 and the blowing unit 100 separately, and the filtering unit 500 and the blowing unit 100 are detachably connected. .

As shown in FIGS. 1 and 2 , the blowing unit 100 is mounted on the filtering unit 500 .

Specifically, the air cleaning and blowing device according to the present invention has an inlet hole through which air is introduced at the rear side and a discharge hole through which air is discharged at the front side, thereby providing a passage through which air flows between the inlet hole and the discharge hole. a filtering unit 500 including a filtering unit housing 510 having a filtering unit housing 510 in which a filter is detachably installed on a flow path through which air flows inside the filtering unit housing; and detachably mounted on a discharge surface of the filtering unit housing of the filtering unit 100 where the discharge hole is formed, and includes a blowing fan for providing negative pressure to the discharge surface, a driving motor for rotationally driving the blowing fan, and the blowing fan. It is possible to provide an air cleaning blower 1000 including a blower unit 100 having a blower unit housing accommodating a fan and the drive motor.

Air is introduced through the rear surface 540 of the filtering unit 500 by the negative pressure generated by the blowing unit 100, and the filtered air is supplied to the front surface 520 of the filtering unit 500. Furthermore, the blower unit 100 may discharge the purified air toward the front surface 520 of the filtering unit 500 .

That is, the air passing through the air cleaning and blowing device according to the present invention may be filtered through the filtering unit 500 disposed at the rear and then blown through the blowing unit 100.

In general, since a filter of an air purifier is disposed behind a flow path so that negative pressure is applied to the surroundings, the air purifying blower according to the present invention also arranges the blower 100 corresponding to the fan to the rear of the flow path.

If the filtering units are stacked in the manner shown in FIGS. 1 and 2 and tightly fastened to the rear of the flow path of the blowing unit, a positive pressure is applied to the filtering unit 500, resulting in increased noise, reduced air volume, or poor performance of the filtering unit. This is because problems such as dust collected in a filter or the like being scattered by positive pressure may occur.

Therefore, in the case of the air cleaning blowing device 1000 of the present invention, the filtering unit 500 is first disposed along the air flow path, and then the blowing unit 100 is disposed so that the filtering unit 500 and the blowing air Negative pressure is applied between the units 100 to smoothly filter and blow air.

Fig. 3 shows a rear perspective view of the filtering unit, and Fig. 4 shows a cross-sectional side view of the air blowing system.

On the other hand, as shown in FIG. 3, the filtering unit 500 has an inlet hole 528 (see FIG. 3) through which air is introduced into the rear side 540, and a discharge through which air is discharged through the front side 520. A filtering unit housing 510 in which a hole 521 is formed to provide a passage through which air flows between the inlet hole 528 and the outlet hole 521, and air flows inside the filtering unit housing 510 It may be provided with a filter 600 to be described later that is detachably installed on the flow path.

The filtering unit housing 510 has a shape of a rectangular parallelepiped elongated in the vertical direction in the drawing, but is not limited thereto and is manufactured in various shapes capable of providing a space capable of accommodating the filter 600 therein. It can be.

The filtering unit housing 510 may be made of synthetic resin or the like to provide ease of manufacture and appropriate strength, and the material is not particularly limited.

As shown in FIGS. 1 and 2 , the filtering unit housing 510 may be provided with a support 550 or the like at the bottom to prevent tipping by matching the height of the housing of the blowing unit 100 to the housing 510 . In addition, the support portion 550 is shown as two, but is not limited thereto and may be appropriately adjusted. In addition, although not shown in the drawing, the support part 550 may be provided with wheels so that the filtering unit 500 can be moved conveniently.

The filtering unit housing 510 may have a rectangular parallelepiped shape extending vertically and accommodates the filter 600 therein. In this case, the filtering unit housing 510 may have a shape substantially corresponding to the filter 600 .

That is, in order to reduce the overall volume of the filtering unit 500 and form a compact structure, the filtering unit housing 510 of the filtering unit 500 has a substantially similar shape to the filter 600 accommodated therein. can

In this case, since the filter 600 may have a substantially elongated rectangular parallelepiped shape, the filtering unit housing 510 also has a rectangular parallelepiped shape elongated vertically corresponding to the external shape of the filter 600. However, there may be a difference in the shape of the filter and the housing.

As described above, the rear surface 540 of the filtering unit housing 510 has an inlet hole 528 through which ambient air is introduced, and an outlet hole 521 through which filtered air is discharged is formed on the front surface 520. As shown in FIG. 3, the inlet hole 528 is formed on the rear surface 540 of the filtering unit housing 510, and the filtering unit housing 510 can sufficiently introduce ambient air. It may be formed on at least half of the rear surface 540 .

The inlet holes 528 may be evenly distributed over the entire area of the rear surface of the housing in a plurality of columns and rows in order to sufficiently utilize the area of a filter, which will be described later.

Meanwhile, referring again to FIG. 2 , the discharge hole 521 provided on the front surface 520 of the filtering unit housing 510 is formed on the front surface 520 of the filtering unit housing 510 to discharge the filtered air. It is supplied toward the blowing unit 100.

Meanwhile, a door part 512 that can be selectively opened may be further provided on the upper side of the filtering unit housing 510 . For example, the door part 512 may be rotatably connected to the filtering unit housing 510 by a hinge shaft 530 so as to open an upper portion of the filtering unit housing 510 .

Accordingly, the filter 600 can be mounted inside the filtering unit housing 510 by rotating the door unit 512 to open the top of the filtering unit housing 510, and vice versa. The filter 600 can be removed from the inside of 510.

Of course, the door part may be formed on the left or right side of the filtering unit, and furthermore, the front or rear surface of the filtering unit housing may be opened.

A connection part 522 selectively connecting the filtering unit 500 and the blowing unit 100 may be provided on the front surface 520 of the filtering unit housing 510 .

The connecting portion 522 may be formed of a protrusion protruding from the front surface 520 of the filtering unit housing 510 through the blowing unit 100 . At this time, an insertion groove (not shown) into which the protrusions are inserted and fixed in a forced fitting manner may be formed on the rear surface of the air blowing housing 110 of the blowing unit 100, and the connecting portion is provided on the side of the blowing unit. The position of the insertion part and the insertion groove may be changed, and it may be configured in the form of a sliding rib and a sliding insertion groove formed to enable sliding fastening rather than the projection and insertion groove method.

On the other hand, the blowing unit 100 has an inlet 134 through which filtered air flows in at the rear side and an outlet 132 through which air is discharged at the front side, so that there is a gap between the inlet 134 and the outlet 132. An air blowing housing 110 providing a flow path A through which air flows, and rotatably provided on the flow path through which air flows inside the air blowing housing 110 to provide negative pressure to the filtered air A fan unit 120 and a driving motor 140 for driving the fan unit may be provided.

The air blowing housing 110 may be configured in various forms, and since it is fastened to the front of the filtering unit housing 510, it is preferable to have a similar shape to the filtering unit housing 510. That is, the air blowing housing 110 may also have a rectangular parallelepiped shape extending vertically.

The air blowing housing 110 may have a support part 150 at a lower portion. As described above, the filtering unit 500 is also provided with a support and the like to prevent the air cleaning blower from collapsing in a fastened state with the blower unit.

Meanwhile, a control unit 140 for manipulating driving of the blower unit 100 may be provided on one surface such as the front surface of the air blower housing 110 .

For example, the operation unit 140 includes a driving operation unit 142 that controls whether the blowing fan 120 is driven, and a driving time adjusting unit 144 that controls the driving time of the blowing fan 120. A control unit in the form of an electric fan may be provided. The control unit may be configured in the form of a button.

A fan unit 120 providing negative pressure to the filtered air discharged from the filtering unit housing 510 may be provided inside the air blowing housing 110 .

The blowing fan 120 is rotatably provided inside the air blowing housing 110, and may be configured as, for example, an axial-flow fan in which an air flow direction and a rotation axis are parallel. For example, the blowing fan 120 may include a rotating shaft 122 and a plurality of blades 121 radially extending from the rotating shaft 122 .

In addition, the blowing fan 120 may be provided with a driving motor 140 or the like at the rear thereof to control the blowing fan 120 . The outlet 132 of the air blowing housing 110 may have a mesh or a frame 136 for filtering foreign substances such as relatively large dust from the blown air, and the frame is integrally configured with the air blowing housing. It can be.

Meanwhile, a power supply unit (not shown) for driving the driving motor 140 of the blowing unit 100 may be further provided.

A filter 600 is mounted inside the filtering unit housing 510 of the filtering unit 500 . The filter 600 adheres closely to the inner surface of the filtering unit housing 510 so that no air passing through the filter 600 is generated inside the filtering unit housing 510 .

Specifically, it comes into close contact with the upper close guide part 770 and the lower close guide part 750 of the filtering unit housing 510 . The configuration of the close guide unit will be described later in detail.

Meanwhile, a fan unit 120 is rotatably provided inside the air blowing housing 110 of the blowing unit 100 . At this time, the diameters of the inlet 134 through which air is introduced and the outlet 132 through which air is discharged of the air blowing housing 110 may be different from each other.

For example, the diameter (D ₂ ) of the inlet 134 allows the filtered air discharged from the filtering unit 500 to flow in as much as possible without resistance and, unlike a circular blowing fan, has a larger corner area than a blowing fan. It may be formed to have the same size as the passage of the filtering unit housing 510 so that negative pressure is applied to the entire area of the filter having a rectangular shape.

On the other hand, the diameter (D ₁ ) of the outlet 132 corresponds to the diameter of the blowing fan like a general box type fan, so that the diameter of the blowing fan or fan unit 120 mounted inside the air blowing housing 110 and It is configured with a substantially similar size, and can provide a sufficient amount of air flow through the outlet.

Therefore, in the case of the present embodiment, the diameter (D ₁ ) of the outlet 132 may be formed to be relatively smaller than the diameter (D ₂ ) of the inlet 134 .

At this time, the flow path A connecting the outlet 132 and the inlet 134 inside the air blowing housing 110 may be formed to gradually decrease from the inlet 134 toward the outlet 132. . In this case, in order to reduce the flow resistance between the inlet 134 and the outlet 132, the inner surface 130 of the flow path A may be configured as a stepped structure or an inclined surface (eg, an inclined plane or an inclined curved surface).

On the other hand, according to the experiment, when the blowing fan 120 is driven to rotate, the air volume is maximized in a ring-shaped area spaced a predetermined distance in the radial direction from the rotating shaft 122 of the blowing fan 120. Found. At this time, the above-described area where the flow rate is maximized (hereinafter, referred to as the 'maximum air volume area') is located at a certain distance in the radial direction from the rotating shaft 122 of the blowing fan 120, and the blowing fan 120 does not exceed the diameter of

In this way, when the blowing fan 120 equipped with an axial flow fan is rotationally driven and the flow rate of air is maximized in the maximum air volume region, the air flow is concentrated in the maximum air volume region, and the air flow is concentrated in the remaining regions. flow is relatively small.

Therefore, when the filtering unit 500 is mounted behind the blowing fan 120, the air flow is concentrated in the filter area corresponding to the maximum air volume area, and foreign substances such as dust can be intensively adsorbed in the area. there is.

In this way, if the flow of air is concentrated in a partial area of the filter 600 and foreign substances are intensively attached thereto, the entire area of the filter may not be used evenly, resulting in a shortened lifespan of the filter.

Therefore, in the case of the air cleaning blower 1000 according to the present embodiment, when the discharge hole 521 of the filtering unit 500 is formed, the air blowing area per unit area in the front surface 520 of the filtering unit 500 It can be configured so that there is a difference in the filter, so that the deviation of the degree of dust collection in the entire filter area can be configured to be minimized.

5 is a front view of the filtering unit 500 viewed from the front.

Referring to FIG. 5 , the filtering unit housing 510 is radially spaced apart from the rotating shaft 122 of the blowing fan 120 by a predetermined distance, and the air blowing area per unit area of the discharge hole is smaller than other areas. A reduction region S1 may be provided. Here, the air volume reduction region S1 corresponds to a region in which the sound pressure applied to the discharge surface by the blowing fan of the above-described blowing unit 100 is large, that is, an air volume maximum region generated in a ring shape, or It may include the maximum area, or may be included in the maximum air volume area.

That is, when the air volume is maximized in the maximum air volume region by the rotational driving of the blowing fan 120, the region including the maximum air volume region on the front surface 520 of the filtering unit housing 510 is called the air volume reduction region S1. ) can be configured.

At this time, the discharge holes 524 and 524' formed in the air volume reduction region S1 may be formed to have a smaller air blowing area per unit area than the discharge holes in other regions.

Referring to (A) of FIG. 5 , in the present embodiment, the discharge hole 524 formed in the air volume reduction region S1 may have a smaller diameter than the discharge holes 526 in other regions. Accordingly, the air blowing area per unit area by the discharge hole 524 formed in the air volume reducing region S1 is smaller than that of other regions.

In addition, referring to (B) of FIG. 5, in the case of the present embodiment, the discharge hole 524' formed in the air volume reduction region S1 is formed to have a smaller density than the discharge hole 526' in other regions. It can be. That is, although the diameters of the discharge holes 524' and 526' are the same, the density per unit area of the discharge holes 524' formed in the air volume reduction region S1 is lower. Accordingly, the sum of air blowing areas per unit area by the discharge holes 524' formed in the air volume reducing region S1 is smaller than other regions.

As a result, the discharge holes 524 and 524' formed in the air volume reduction area S1 on the front surface 520 of the air blowing housing 110 have a smaller diameter or a lower density than other areas. As a result, the deviation of the negative pressure formed in the filter is reduced, so that the negative pressure is uniformly applied to the filter for each region, so that the deviation of the dust collection amount for each region of the filter can be minimized.

In summary, the sum of the discharge hole area per unit area adjusted by the size of the unit discharge hole on the discharge surface, which is the side (front surface) on which the discharge hole is formed of the filtering unit housing constituting the filtering unit, or the number of discharge holes per area, may vary for each region. can

6 is an exploded perspective view of an air cleaning blower 1000 according to another embodiment of the present invention.

Referring to FIG. 6 , the discharge holes 524 and 526 formed on the front surface 520 of the filtering unit 500 are formed to have a smaller air blowing area per unit area in the air volume reducing region S1 as described above. .

For example, FIG. 6 shows a case where the discharge hole 524 formed in the air volume reduction region S1 has a smaller diameter than the discharge hole 526 in other regions. Since other components have already been described above, repetitive descriptions will be omitted.

Meanwhile, FIG. 7 shows an example of a filter 600 mounted inside the filtering unit 500 according to the present invention. Although one filter 600 is shown as being provided inside the filtering unit 500, it is not limited thereto, and a configuration in which a plurality of filters are provided inside the filtering unit 500 is of course also possible.

Referring to FIG. 7 , the filter 600 may include, for example, at least one of a pre-filter, an antibacterial filter, a HEPA filter, or a deodorizing filter made of activated carbon, and a plurality of filter layers are unified. can be a filter.

Furthermore, in the case of the above-described embodiment, the filter 600 has a substantially rectangular parallelepiped shape as shown in FIG. 7 and has sizes of height (H), width (W), and thickness (T). .

In this case, the filter 600 is in close contact with the inner surface of the filtering unit housing 510 so as to cover the entire passage inside the filtering unit housing 510, that is, to prevent air passing without passing through the filter 600. will do

When the size of the filter 600 is changed within a relatively small range, the edge of the filter 600 comes into close contact with the inner surface of the filtering unit housing 510 by a close guide unit described later.

However, when the size of the filter 600 is changed, the size change of the filter may not be handled even by the close guide part. In this case, since the filtering unit housing 510 suitable for the size of the filter 600 must be manufactured separately, it can be a burden on the manufacturer.

Therefore, in this embodiment, when the filter 600 is mounted, a filter in which the height H, width W, and thickness T of the filter 600 converge within a certain range is used.

For example, the filter 600 may be a vehicle air conditioner filter having a thickness of 15 to 40 millimeters (mm) and a width or height of 170 to 260 millimeters (mm).

Therefore, when the vehicle air conditioner filter is applied to the filter, there is no need to manufacture a separate filter for the air cleaning blower 1000 according to the present invention, and furthermore, since the size of the filter is placed within a certain range, the filtering unit housing of the filtering unit There is a convenience that can be manufactured according to the size of the filter.

In general, there are many cases in which a price difference between a dedicated filter of an air purifier and an air conditioner filter for a vehicle occurs by 10 to 20 times. That is, since air purifier manufacturers can have a structure in which air purifier manufacturers exclusively sell filters without competition through exclusive filters, users have little right to decide on filters.

However, in the case of vehicle air conditioner filters, although there is a variation in size by vehicle type, the price is significantly cheaper than air purifier filters, so their use, such as price, presence or absence of pre-filter, fine dust removal grade, presence or absence of activated carbon filter layer, filter layer Depending on conditions such as the number of filters and manufacturers, various price and quality filters can be determined according to personal preference factors.

Since these various filters may vary in size depending on the type of vehicle, the filtering unit may be configured so that a filter of a dedicated size can be applied according to the size of the housing of the filtering unit constituting the filtering unit. It may be configured to correspond to a vehicle air conditioner filter of the size. Explain in detail.
