Recently, the air quality has deteriorated significantly due to yellow dust and fine dust, and accordingly, the demand for air purifiers that supply clean air by filtering the air is increasing rapidly.

However, there is a difference in the frequency or necessity of using air purifiers in winter and summer according to seasonal changes in wind direction.

In the summer season, a fan or other blower is widely used, and in winter, a blower or air conditioner is rarely used, but the concentration of fine dust increases, so the need for an air purifier is high.

As a result, there are many cases where both an air purifier and a blower are provided and necessary equipment is selectively used in a living space or a work space such as a home.

However, it may be best to use the necessary devices according to seasonal changes by providing a ventilation device such as a fan and an air purifier for each season, but there were many situations where it was difficult for reasons of space or cost to store the two devices.

A fan is a device that blows air by rotating a fan by a motor, and in the case of an air purifier, products with various functions and designs are introduced, but the core function of an air purifier is to form a pneumatic difference before and after the filter to include fine dust, etc. The filtered air passes through the filter and pollutants are collected through the filter. Therefore, it can be seen that various sensors, housings, or displays are not the core components of the air purifier.

However, in the case of a conventional air purifier, in addition to the initial cost of purchasing a high-end device, it is necessary to use a dedicated filter to replace it, so when the filter replacement time arrives and the filter is replaced, the cost burden of the filter replacement is remarkably high and the burden on the user. There is a problem of increasing the.

In addition, in the case of air purifiers, the frequency of use by season varies depending on the wind direction according to the change of seasons.Therefore, the fan is often taken out and used in the season when the fine dust concentration is low, but the air purifiers occupying a large volume are stored when not in use.

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 may be thorough and complete, and the spirit of the present invention may be sufficiently conveyed to those skilled in the art. The same reference numbers throughout the specification indicate the same elements.

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 purifying blower 1000 includes a filter 600 to filter foreign substances in the air and provide filtered air to the filtering unit 500 and the filtering unit 500. It is detachably connected, and includes a blowing unit 100 for supplying and blowing 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 providing a blowing function and selectively in 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 blowing unit 100 may be configured in a so-called'box-type fan' shape, and the filtering unit 500 may be stacked or closely coupled to the blowing unit 100. It may be configured in a rectangular box shape, but is not limited thereto.

That is, each of the filtering unit housing 510 and the blowing unit housing 110 has a thickness smaller than each width or height, and the filtering unit and the blowing unit may be stacked or installed in close contact with each other.

Therefore, in the season when the necessity of the air cleaning function is relatively low, for example, in the summer season, the filtering unit 500 is removed and the blowing unit 100 is used for a purpose such as a fan, and the necessity of the air cleaning function is relatively high. In seasons, for example, in winter, the filtering unit 500 may be added to the blowing unit 100 to be used as an air purifier. Of course, it may be used in a state in which the filtering unit 500 is mounted on the blowing unit 100 irrespective of the seasonal change.

Accordingly, the air cleaning blowing device 1000 is provided with the filtering unit 500 and the blowing unit 100 separately, and the filtering unit 500 and the blowing unit 100 are configured to be detachably connected. .

1 and 2, the blowing unit 100 is mounted on the filtering unit 500.

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

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

That is, the air passing through the air cleaning 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 the filter of the air purifier arranges a fan or the like at the rear of the flow path so that a negative pressure is applied to the surroundings, the air purifying blower according to the present invention also has a blower 100 corresponding to the fan, etc. disposed at the rear of the flow path.

If the filtering units are stacked in the manner shown in FIGS. 1 and 2 and are closely coupled to the rear of the blowing unit flow path, positive pressure is applied to the filtering unit 500, thereby increasing noise, reducing air volume, or This is because a problem such as scattering of dust collected on a filter or the like by positive pressure may occur.

Therefore, in the case of the air purifying blower 1000 of the present invention, the filtering unit 500 is first arranged along the flow path of the air, and then the blowing unit 100 is arranged, so that the filtering unit 500 and the blowing A negative pressure is applied between the units 100 to smoothly filter and blow the air.

3 is a rear perspective view of the filtering unit, and FIG. 4 is a side cross-sectional view of the air cleaning blowing device.

Meanwhile, 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 surface 540, and discharges the air through the front surface 520. A filtering unit housing 510 having a hole 521 formed therein to provide a flow path through which air flows between the inlet hole 528 and the discharge hole 521, and air flows inside the filtering unit housing 510 A filter 600 to be described later that is detachably installed on the flow path may be provided.

In the drawing, the filtering unit housing 510 has a shape of a rectangular parallelepiped that extends substantially in the vertical direction, but is not limited thereto and is manufactured in various shapes that can provide a space for accommodating the filter 600 therein. Can be.

The filtering unit housing 510 may be made of synthetic resin or the like in order 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 part 550 or the like at the lower part to prevent a fall by matching the height with the housing of the blowing unit 100. In addition, the support part 550 is shown as two, but is not limited thereto and may be appropriately adjusted. Further, although not shown in the drawings, the support part 550 may be provided with a wheel or the like to facilitate movement of the filtering unit 500.

The filtering unit housing 510 may have a rectangular parallelepiped shape that extends 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 shape substantially similar to the filter 600 accommodated therein. I can.

In this case, since the filter 600 may have a shape of a substantially elongated rectangular parallelepiped, the filtering unit housing 510 also has a shape such as a rectangular parallelepiped extending vertically in correspondence with the external shape of the filter 600. It can have, but it is okay to have a difference in the shape of the filter and the housing.

As described above, an inlet hole 528 through which ambient air is introduced is formed in the rear surface 540 of the filtering unit housing 510, and formed in the exhaust hole 521 through which the filtered air is discharged. 3, the inlet hole 528 is formed in the rear surface 540 of the filtering unit housing 510, and It may be formed in at least half of the rear surface 540.

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

Meanwhile, referring to FIG. 2 again, a discharge hole 521 provided in the front surface 520 of the filtering unit housing 510 is formed in the front surface 520 of the filtering unit housing 510 to collect 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 an 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 to open the 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 part 512 to open the upper portion of the filtering unit housing 510, and conversely, the filtering unit housing The filter 600 may be removed from the inside of the 510.

Of course, the door portion may be formed on the left or right side of the filtering unit, and further, the front or rear side of the filtering unit housing itself may be opened.

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

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

Meanwhile, the blowing unit 100 has an inlet 134 through which filtered air is introduced at the rear side, and an outlet 132 through which air is discharged is formed on the front side, and between the inlet 134 and the outlet 132 A blowing unit housing 110 that provides a flow path A through which air flows, and a flow path through which air flows inside the blowing unit housing 110 is rotatably provided to provide a negative pressure to the filtered air. A fan unit 120 and a driving motor 140 for driving the fan unit may be provided.

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

The blowing unit housing 110 may include a support part 150 at a lower portion. As described above, the filtering unit 500 is also provided with a support part, etc., so as to prevent collapse of the air cleaning blowing device in a fastened state with the blowing unit.

On the other hand, a manipulation unit 140 for operating the driving of the blowing unit 100 may be provided on one surface such as a front surface of the blowing unit housing 110.

For example, the operation unit 140 includes a driving operation unit 142 that controls whether or not the blowing fan 120 is driven, and a driving time control unit 144 that adjusts the driving time of the blowing fan 120. An adjustment unit in the form of being provided in the fan may be provided. The operation unit may be configured in the form of a button.

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

The blower fan 120 is rotatably provided inside the blower unit housing 110 and may be configured as 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 rotation shaft 122 and a plurality of blades 121 extending radially from the rotation 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 blowing unit housing 110 may be provided with a mesh or frame 136 for filtering foreign substances such as relatively large dust from the blown air, and the frame is formed integrally with the blowing unit housing. 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 is in close contact with the inner surface of the filtering unit housing 510 so as not to generate air passing through the filter 600 from the inside of the filtering unit housing 510.

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

Meanwhile, a fan unit 120 is rotatably provided inside the blowing unit housing 110 of the blowing unit 100. In this case, the diameters of the inlet port 134 through which air is introduced and the outlet port 132 through which air is discharged from the blowing unit 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, a larger size than a blowing fan and a corner area In order to apply negative pressure to the entire area of the filter having a rectangular shape, it may be formed to have the same size as the flow path of the filtering unit housing 510.

On the other hand, the diameter (D ₁ ) of the discharge port 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 blowing unit housing 110 It is constructed of approximately the same size, and can provide a sufficient amount of airflow through the outlet.

Accordingly, in 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.}

In this case, a flow path A connecting the outlet 132 and the inlet 134 from the inside of the blowing unit 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 port 134 and the outlet port 132, the inner surface 130 of the flow path A may have a stepped structure or an inclined surface (such as an inclined plane or an inclined curved surface).

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

In this way, when the blower fan 120 provided with an axial fan, etc. is rotationally driven, when the flow rate of air reaches the maximum in the maximum air volume region, the flow of air is concentrated in the maximum air volume region and the air flow is concentrated in the remaining region. The flow will be relatively small.

Therefore, when the filtering unit 500 is mounted at the rear of the blowing fan 120, the flow of air is concentrated in the filter area corresponding to the maximum air volume area, so that foreign substances such as dust can be intensively adsorbed in the area. have.

As described above, when the flow of air is concentrated in a partial area of the filter 600 and foreign substances are intensively attached, the entire area of the filter cannot be used evenly, resulting in shortening the life of the filter.

Therefore, in the case of the air purifying 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 to minimize the deviation of the degree of collecting dust in the entire filter area by configuring the difference to exist.

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

5, the filtering unit housing 510 is spaced a predetermined distance from the rotation shaft 122 of the blowing fan 120 in a radial direction, and the air blowing area per unit area of the discharge hole is smaller than that of other areas. A reduction area 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 blower fan of the blower unit of the above-described blower unit 100 is large, that is, the 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 air volume maximum region by rotational driving of the blowing fan 120, the air volume reduction region S1 in the front surface 520 of the filtering unit housing 510 including the air volume maximum region. ).

In this case, 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 FIG. 5A, in the present embodiment, the discharge hole 524 formed in the air volume reduction region S1 may be formed to have a diameter smaller than that of the discharge hole 526 in other regions. Accordingly, the air blowing area per unit area due to the discharge hole 524 formed in the air volume reduction area S1 is smaller than that of other areas.

In addition, referring to FIG. 5B, in the case of this embodiment, the discharge hole 524' formed in the air volume reduction area S1 is formed to have a smaller density than the discharge hole 526' in other areas. 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 lowered. Accordingly, the sum of the air blowing areas per unit area by the discharge holes 524 ′ formed in the air volume reduction area S1 is smaller than that of other areas.

As a result, the discharge holes 524 and 524 ′ formed in the air volume reduction region S1 in the front surface 520 of the blowing unit housing 110 have a smaller diameter or lower density than other regions. As a result, the deviation of the sound pressure formed in the filter is reduced, so that the even sound pressure is applied to the filter by region, thereby minimizing the deviation of the amount of dust collected by the filter region.

In summary, the sum of the area of the discharge holes per unit area, which is controlled by the size of the unit discharge holes on the discharge surface, which is the side (front) of the filter unit housing that constitutes the filtering unit, or the number of discharge holes per area, may vary by area. I can.

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

6, the discharge holes 524 and 526 formed in 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 reduction area S1 as described above. .

For example, FIG. 6 shows a case in which the discharge hole 524 formed in the air volume reduction region S1 is formed to have a smaller diameter than the discharge hole 526 in another region. Since the other components have already been described above, a repetitive description 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 it is shown that one filter 600 is 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 possible.

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

Further, in the case of the above-described embodiment, the filter 600 has a substantially rectangular parallelepiped shape as shown in FIG. 7 and has a size 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 all flow paths from the inside of the filtering unit housing 510, that is, to prevent air passing through the filter 600. It is done.

When the size of the filter 600 changes within a relatively small range, the edge of the filter 600 is brought into close contact with the inner surface of the filtering unit housing 510 by a contact guide to be 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 contact guide part. In this case, since the filtering unit housing 510 that fits the size of the filter 600 must be separately manufactured, it may be a burden for the manufacturer.

Accordingly, in the case of the present embodiment, when the filter 600 is mounted, a filter in which the sizes of 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 an air conditioner filter for a vehicle that satisfies a range of 15 to 40 millimeters (mm) in thickness and 170 to 260 millimeters (mm) in width or height.

Therefore, when the vehicle air conditioner filter is applied to the filter, it is not necessary to manufacture a separate filter for the air cleaning blower 1000 according to the present invention, and further, 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, the price difference between the exclusive filter of the air purifier and the air conditioner filter for a vehicle is often 10 to 20 times. That is, through the dedicated filter, air purifier manufacturers can have a structure in which filters are sold exclusively without competition, so that users have little authority to decide on a filter.

However, in the case of vehicle air conditioner filters, there are variations in size for each vehicle type, but the price is considerably cheaper than filters dedicated to air purifiers, 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 Filters of various prices and quality may be determined according to personal preference factors according to conditions such as the number of and manufacturers.

Since such various filters may have their size deviation depending on the vehicle type, the filtering unit may be configured so that a filter of a dedicated size can be applied to fit the size of the filtering unit housing constituting the filtering unit. However, the filtering unit of the present invention has various types of filters. It may be configured to correspond to the size of the vehicle air conditioner filter. It will be described in detail.

8 is a cross-sectional view of the filtering unit housing 510 constituting the filtering unit 500 as viewed from the front.

Referring to FIG. 8, inside the filtering unit housing 510, the edge of the filter 600 is in close contact with the inner surface of the filtering unit housing 510, so that the flow path through which the air flows is provided with the filter 600. It may be provided with a contact guide portion (710, 730, 750, 770) to be completely covered by.

When the edge of the filter 600 does not come into close contact with the inner surface of the filtering unit housing 510, air leaks through the spaced space, thereby generating a flow of air that is not filtered by the filter 600. Since this reduces the filtering effect by the filter 600, the edge of the filter 600 is in close contact with the inner surface of the filtering unit housing 510 to minimize or eliminate the flow of air that does not pass through the filter 600. It is necessary to do.

At this time, one edge of the filter 600 presses and pushes the first side wall contact guide 730, and the first side wall contact guide 730 is an elastic member 734 as shown in the drawing. As is compressed, it retreats toward the inner surface. In addition, when the first sidewall contact guide part 730 is pushed by the filter 600, it may be displaced along the slope of the inclined sliding part 733 to minimize friction or interference.

In this case, the contact plate 732 of the first side wall contact guide part 730 comes into close contact with one edge of the filter 600.

Meanwhile, in this case, in order to more reliably guide the position of the filter 600, guide grooves 772 and 752 (refer to FIG. 4) may be formed in the first side wall contact guide 730.

4, guide grooves 772 and 752 are formed in the upper contact guide part 770 and the lower contact guide part 750, respectively, and the first side wall contact guide part 730 and the second side wall are in close contact. Likewise, a guide groove (not shown) may be formed in the guide part 710.

Therefore, when the filter 600 is inserted and mounted inside the filtering unit housing 510, both edges of the filter 600 are connected to the first side wall contact guide part 730 and the second side wall contact guide part. It can be installed by inserting into the guide groove of (710).
