Description

Humidifying Purifier {Air Cleaner Having Humidifying Function}

The present invention relates to a humidifying purifier having an air purifying function and a humidifying function, and to a humidifying purifier capable of adjusting a humidifying function and a humidifying amount.

Air purifier is a device that purifies contaminated air and converts it into fresh air. It functions to remove dust and germs and remove odor by passing the introduced air through the air purifying filter.

Due to the increase in yellow dust or harmful dust, air pollution is becoming serious. Accordingly, the necessity and demand for air purifiers are increasing significantly due to an increase in respiratory diseases and a social atmosphere such as heightened public interest in health.

A general air purifier includes a blower fan that inhales air to be purified, a filter assembly that purifies the air, and the like.

Meanwhile, the air purifier may include a humidifying filter to supply humidified air in addition to the air purifying filter, and the humidifying purifier having a humidifying function regulates indoor humidity by discharging air containing moisture.

The humidifying purifier is provided with a humidifying filter at the rear end of the air purifying filter, and a fan for suctioning air is installed at the rear end of the humidifying filter. At this time, some of the air that has passed through the air purification filter passes through the humidifying filter and flows into the blowing fan, but the remaining air flows directly into the blowing fan without passing through the humidifying filter.

Therefore, the conventional humidifying purifier does not have a structure in which all the air that has passed through the air purifying filter passes through the humidifying filter, so that the humidifying efficiency is reduced when the humidifying mode is selected.

In order to solve this problem, a flow path changing means is sometimes used to increase the flow rate of air supplied to the humidifying filter in the humidifying mode. However, even if a flow path changing means is used, not all air that has passed through the air purifying filter is supplied to the humidifying filter, and thus there is a limitation in improving humidifying efficiency.

In addition, the conventional humidifying purifier has a problem in that air cleaning efficiency is deteriorated in an air cleaning exclusive mode in which humidification is not performed because some of the filtered air is supplied to the humidifying filter through an air purifying filter.

In addition, the conventional humidifying purifier has a problem in that the installation area of the humidifying purifier is increased due to the installation of the humidifying filter since the air purifying filter, the humidifying filter, and the blowing fan are sequentially installed from the inlet.

For example, the suction port 111 may be installed on at least a portion of the front, rear, left, and right surfaces of the housing 110 to suck air in various directions, and a plurality of discharge ports 112 may also be installed.

In addition, the air purification filter 120 may be installed on the front surface of the blower 130 so that the air introduced from the intake 111 is filtered through the air purification filter 120 and then introduced into the blower 130. The installation location is not limited.

The air purification filter 120 may be provided inside the housing 110 to be configured to filter the air flowing through the intake 111.

For example, the air purification filter 120 may be disposed in the air passage after the intake 111. The air purifying filter 120 may be configured in a quadrangular shape corresponding to the shape and cross-sectional area of the air flow path. Through this, the air introduced through the intake 111 of the housing 110 is the total amount of the air purifying filter 120 Can pass through. However, the shape of the air purification filter 120 is not limited thereto, and various known types of filters may be used. For example, the air purification filter 120 may be formed of a three-dimensional filter having a circular or square cross section and a space formed therein.

In addition, the air purification filter 120 may be selected from filters having various shapes and functions, and the type, number, and shape of the filters are not limited to the example shown in FIG. 1 and various changes are possible.

Then, the blowing unit 130 provides a blowing force to flow the air introduced from the suction port 111 to the discharge port (112). Between the inlet 111 and the outlet 112, an air flow path through which air flows is formed by driving the blower 130, and these air flow paths are located at the inlet 111 and the outlet 112, and blowers Various changes are possible according to the suction/discharge position and direction of 130.

In addition, the blowing unit 130 is provided with a blowing fan 131 for flowing air. As illustrated in FIG. 1, the blowing fan 131 may have a structure disposed at the rear of the air cleaning filter 120 based on the air flow path and sucked from one side, but its installation position and suction structure Various modifications are possible without being limited to the illustration of FIG. 1. For example, the blowing fan 131 may have a positive suction structure.

In addition, the blowing unit 130 may include a fan casing 140 surrounding the blowing fan 131 and having an inlet 141 and an outlet 142 (see FIG. 11 for the specific shape of the fan casing). .

As described above, when the fan casing 140 is provided, air can be efficiently flowed to correspond to the air flow path. For example, as shown in FIG. 1, the pan casing 140 has a structure in which air introduced from the inlet 141 of the front of the pan casing 140 flows to the outlet 142 of the upper surface of the pan casing 140. Can have However, the pan casing 140 is not limited to the shape shown in FIG. 1, and the direction or number of the inlets 141 and the outlets 142 can be variously changed. On the other hand, the humidifier purifier 100 according to an embodiment of the present invention may not be provided with a fan casing 140 in the blower 130, to guide the air flow from the inlet 111 to the outlet 112 A separate flow path guiding means may be provided.

In addition, the humidifying unit 150 may be provided at a rear end of the blowing unit 130 to be configured to humidify the air discharged from the blowing unit 130. That is, the humidification unit 150 may be installed in a space between the blowing unit 130 and the discharge port 112 to filter the air purification filter 120 and then humidify the air passing through the blowing unit 130.

As described above, when the humidifying unit 150 is provided at the rear end (that is, the upper portion) of the blowing unit 130, all the air that has passed through the air purification filter 120 flows into the blowing unit 130, and then the humidifying unit 150 Since it is introduced into the humidification performance can be improved.

The humidifying unit 150 may include a humidifying member 160 made of a hygroscopic material to perform humidification through vaporization of the absorbed water, and a water tank 151 in which humidifying water is accommodated. That is, the humidifying member 160 is immersed in a water tank to absorb water, and when the air flows through the blower 130, the absorbed water is vaporized to be humidified.

In addition, the humidification unit 150 may further include a water tank 155 for supplying water to the water tank 151. Since the water supply structure between the water tank 151 and the water tank 155 is a technique widely used in a humidifier, detailed description will be omitted.

2 and 3, the water tank 151 is formed with a receiving space 152 for receiving water so that the humidifying member 160 is immersed. For reference, FIG. 2 shows the external shape of the humidification adjusting unit 170 and the humidifying member 160 on the cross section of the water tank 151 so that the relationship between the humidifying member 160 and the water tank 151 can be easily confirmed.

The water tank 151 is configured to enable rotation of the humidifying member 160 as described later, and even when rotation of the humidifying member 160 is made, the lower end 167 of the humidifying member 160 is provided to the water tank 151. It is configured to be immersed in the received water. At this time, an extension 151a protruding downward may be formed at the lower portion of the accommodation space 152 to prevent interference with the lower end 167 of the humidifying member 160 when the humidifying member 160 rotates. However, the expansion portion 151a is not necessarily required, and the lower surface of the receiving space 152 of the water tank 151 is configured to have a depth corresponding to the bottom surface of the expansion portion 151a, so that when the humidifying member 160 is rotated, It may have a structure to prevent interference with the lower end 167 of the humidifying member 160.

In addition, the shaft support portion 151b may be formed in the water tank 151 so that the rotating shaft of the humidifying member 160 can be installed in the water tank 151. In FIG. 3, the shaft support portion 151b is configured to have a groove shape, but may be formed in a hole shape through which the rotation shaft passes.

In addition, the avoidance groove 151c may be formed in the side surface of the water tank 151 to avoid interference with the body portion of the water tank 151 when the humidifying member 160 rotates. In this case, the receiving space 152 of the water tank 151 can receive water to a position lower than the height of the interference avoiding groove 151c.

In addition, the inner wall surface of the water tank 151 may be provided with a stopper (151d) to the lower end 167 of the humidifying member 160 to limit the maximum rotational position of the humidifying member 160.

2 to 4, the humidifying member 160 includes a humidifying filter 161 that absorbs water contained in the water tank 151 and a humidifying filter 161 to maintain the shape of the humidifying filter 161 It may be provided with a frame 165 installed on the outside.

The humidifying filter 161 is made of a hygroscopic material, and the frame 165 may be made of a material having strength to maintain the appearance of the humidifying filter 161 such as synthetic resin.

In addition, the humidifying filter 161 may have a plate-shaped structure, and the frame 165 has a structure supporting a periphery of the plate-shaped humidifying filter 161.

At this time, the frame 165 may have a grid 165 structure so that the blown air can pass through the humidifying filter 161. Referring to FIG. 3, in order to prevent the end portion of the humidifying filter 161 from being deformed by wind pressure when blowing, the grid 166 is configured such that a portion located far from the rotation axis of the humidifying member 160 has a dense structure. Can be. In addition, referring to FIG. 4, the frame 165 may not have a lattice formed in some areas so that the humidification filter 161 can be separated and mounted.

On the other hand, the inside of the housing 110 is formed a discharge flow path (AF) that is a flow space of air discharged from the blower 130 to the discharge port 112 side, the humidification adjustment unit 170 is a humidification member 160 is a discharge flow path (AF) is configured to move the humidifying member 160 to open or block at least a portion. At this time, when the blowing unit 130 is provided with a fan casing 140, the discharge flow path AF corresponds to a space in which air flows from the outlet 142 of the fan casing 140 toward the discharge port of the housing 110. do.

The humidification adjustment unit 170 is configured to include a motor driven by the control unit (C) may be configured to rotate the humidifying member 160. At this time, the humidification adjustment unit 170 may be installed in the water tank 151, as shown in FIG.

As described above, the humidifying member 160 is rotated by the humidifying adjustment unit 170, and it may be determined whether to humidify the filtered air through the air purifying filter 120 according to the position of the humidifying member 160.

For example, in the case where the humidifying member 100 rotated by the humidifying adjustment unit 170 is in the position shown in FIG. 1, the humidifying purifier 100 has a clean only mode in which humidification is not performed and only air cleaning is performed. When the humidifying member 160 is in the position shown in FIG. 5, a high-humidity clean mode in which air cleaning and maximum humidification is performed is performed, and when the humidifying member 160 is in the position shown in FIG. A low-humidity clean mode in which air cleaning and some humidification may be performed may be performed.

That is, the opening degree of the discharge flow path AF is changed according to the position of the humidifying member 160 moved by the humidifying adjustment unit 170, filtered through the air purification filter 120, and then passed through the blowing unit 130. The humidification amount of air may be adjusted according to the position of the humidifying member 160.

1, 5, and 6, a clean-only mode, a low-humidity clean mode, and a high-humidity clean mode will be described in more detail.

As shown in FIG. 1, when the humidifying member 160 is in the first position arranged in the vertical direction, the humidifying member 160 completely opens the discharge flow path AF. That is, in the first position, the humidifying member 160 is positioned parallel to the flow direction of the air flowing through the discharge passage AF, so that the discharge passage AF can be completely opened. Therefore, the air coming out of the outlet 142 after being filtered through the air cleaning filter 120 is discharged through the outlet 112 without going through the humidifying member 160, so a clean dedicated mode in which humidification is not performed is performed.

As shown in FIG. 5, when the humidifying member 160 is in a second position disposed in an oblique direction close to the horizontal, the humidifying member 160 completely blocks the discharge flow path AF. That is, in the second position, the humidifying member 160 is positioned to be inclined close to approximately 90 degrees in the flow direction of the air flowing through the discharge flow path AF to completely block the discharge flow path AF. Therefore, since the air coming out of the outlet 142 after being filtered through the air cleaning filter 120 passes through the humidifying member 160 and is discharged through the outlet 112, a high-humidity clean mode in which a large amount of humidification is performed is performed. do.

On the other hand, in FIG. 5, the humidifying member 160 is configured to have a slight inclination, but the humidifying member 160 is completely in a high-humidity clean mode by changing the position of the rotating shaft of the humidifying member 160 and the structure of the water tank 151. It can also be configured to be horizontal.

As such, the humidifying member 160 may be configured to be rotatable between a first position that opens the discharge flow path AF and a second position that blocks the discharge flow path AF, through which humidification is performed. Can be determined.

On the other hand, as shown in Figure 6, the humidifying member 160 may have a third position arranged to have a slight inclination. That is, in the third position, the humidifying member 160 is inclined in the flow direction of the air flowing through the discharge flow path AF, but since the inclination angle formed with the flow direction of air is smaller than that in the second position, the humidifying member 160 Will open (block) some of the discharge passages (AF). That is, the area in which the humidifying member 160 blocks the discharge passage AF in the third position is smaller than the area in which the discharge passage AF is blocked in the second position. Therefore, after filtering through the air cleaning filter 120, some of the air coming from the outlet 142 passes through the humidifying member 160 and is discharged through the outlet 112, and the rest of the air does not pass through the humidifying member 160. Since it is discharged directly through the discharge port 112, a low-humidity clean mode with less humidification is performed than in the case shown in FIG.

At this time, the control unit (C) drives the humidification adjustment unit 170 so that the humidifying member 160 is positioned at any third position between the first position shown in FIG. 1 and the second position shown in FIG. 5. The member 160 can be rotated.

In addition, as shown in Figure 1 (b), Figure 5 (b) and Figure 6 (b), when projecting the humidifying member 160 to the outlet 142 of the pan casing 140, the humidifying member 160 ), the area of the humidifying member 160 covering the discharge flow path AF and the outlet 142 of the pan casing 140 is changed, and through this, whether humidification and the humidification amount can be adjusted.

Meanwhile, in FIGS. 1(a), 5(a), and 6(a), the humidifying member 160 is illustrated as being positioned at a distance from the outlet 142 of the pan casing 140. However, in order to minimize the phenomenon that the air discharged from the outlet 142 is discharged by bypassing the humidifying filter 160, the humidifying member 160 in the state of Figure 5 (a) is the outlet 142 of the pan casing 140 ), it is also possible to arrange the water tank 151 in which the humidifying member 160 is installed at a lower position than the water tank 151 in FIG. 5(a).

As described above, the humidifying purifier 100 according to the first embodiment of the present invention can implement a clean-only mode, a high-humidity clean mode, and a low-humidity clean mode through rotation of the humidifying member 160, so that the amount of dust and the amount of humidity It is possible to determine whether or not to humidify based on the humidification amount can be adjusted when the humidification is made. In particular, since the low-humidity clean mode shown in FIG. 6 can adjust the amount of humidification in various stages by adjusting the rotational position of the humidifying member 160, there is an advantage that fine adjustment of the humidification amount is possible.

In addition, since the humidifying member 160 is installed at the rear end of the air cleaning filter 120 and the blowing unit 130 (that is, the upper part of the housing), in the case of a high-humidity clean mode, all air that has passed through the air cleaning filter 120 is transmitted. Since it flows into the humidifying unit 150 through the abundance 130, the humidifying performance may be improved. In addition, in the case of the clean-only mode, all air that has passed through the air purification filter 120 is discharged through the discharge port 112 without passing through the humidifying unit 150 through the blowing unit 130, thereby maximizing air cleaning efficiency. In particular, since the discharge flow path AF used in the clean exclusive mode is used as it is in the humid clean mode, it is advantageous in that the structure is simple since no dedicated flow path for humidification is required.

In addition, since a structure in which the humidifying member 160 is directly rotated is used to implement a high-humidity clean mode, a low-humidity clean mode, and a clean-only mode, a separate flow path changing means required in the prior art is not required.

In addition, since the humidifying unit 150 is located at the upper portion of the blowing unit 130, the air purifying filter, the humidifying unit, and the blowing unit can reduce the installation area compared to the conventional structure in which they are arranged in a straight line. In addition, since the humidifying filter 161 is located adjacent to the discharge port 112, it is possible to easily check and clean whether the humidifying filter 161 is contaminated, thereby improving hygiene.

Next, a modified example of the humidifying purifier 100 according to the first embodiment of the present invention will be described with reference to FIGS. 7 to 9.

7 is a perspective view showing a humidifying unit provided in a modification to the first embodiment of the present invention, Figure 8 is a schematic diagram showing the operating state in the clean only mode of the humidifying unit shown in Figure 7, Figure 9 is Schematic diagram showing the operating state in the high-humidity clean mode of the humidifying unit shown in FIG.

In the case of the modified example shown in FIGS. 7 to 9, the rest of the configuration except for the shape and operation structure of the humidifier 150 is the same as the first embodiment described with reference to FIGS. 1 to 6, and thus a detailed description of the same configuration Will be omitted and only the configuration of the humidification unit 150 will be described.

As illustrated in FIGS. 7 to 9, the humidifying unit 150 according to the modified example may include a pair of humidifying members 160 installed facing each other. At this time, the water tank 151 is configured to achieve a state in which a pair of humidifying members 160 are immersed, and water may be supplied from the water tank 155 to the water tank 151.

In addition, both sides of the water tank 151 may have a structure in which water supplied from the water tank 155 can be simultaneously supplied to a portion of the water tank 151 in which a pair of humidifying members 160 are installed. For example, as illustrated in FIG. 7, the water tank 151 may have a “U” shape.

In addition, the water tank 151 may have an opening 153 corresponding to the discharge flow path AF in the space between the pair of humidifying members 160. At this time, the opening 153 may have a shape corresponding to the rectangular shape of the outlet 142 of the pan casing 140 shown in FIG. 1. At this time, the humidification unit 150 may be disposed above the blower 130 so that the long side portion of the opening 153 where the humidifying member 160 is installed corresponds to the long side portion of the outlet 142.

In addition, the pair of humidifying members 160 may be configured to open or block at least a portion of the discharge flow path AF by rotating by the humidifying adjustment unit 170.

For example, as shown in FIG. 8, when the pair of humidifying members 160 are in a first position standing parallel to the discharge flow path AF, that is, in the vertical direction, the discharge flow path AF The air discharged through does not pass through the humidifying member 160. Accordingly, when the humidifying member 160 is in the first position shown in FIG. 8, a clean only mode in which humidification is not performed may be performed.

And, as shown in Figure 9, when the pair of humidifying member 160 is disposed inclined in the discharge passage (AF) while the upper end of the humidifying member 160 is placed in contact with each other (when in the second position) ), the air discharged through the discharge passage AF passes through the humidifying member 160. Therefore, when the humidifying member 160 is in the second position shown in FIG. 9, a high-humidity clean mode in which humidification is performed at a high level can be performed.

In addition, although not shown, when the pair of humidifying members 160 are disposed to be inclined in the discharge flow path AF, but the upper ends of the humidifying members 160 are not in contact with each other (when in the third position), Some air discharged through the discharge passage AF passes through the humidifying member 160, and the remaining air does not pass through the humidifying member 160. In this case, a low-humidity clean mode may be performed in which humidification is lower than that shown in FIG. 9.

On the other hand, the humidification adjustment unit 170 is provided on each of the pair of humidifying members 160 may be configured to rotate the pair of humidifying members 160 independently of each other. Accordingly, the humidification adjusting unit 170 rotates the humidifying member 160 so that the humidifying member 160 is disposed at an arbitrary third position between the first position shown in FIG. 8 and the second position shown in FIG. 9. The humidification amount can be adjusted. In addition, since it is possible to independently drive the pair of humidifying members 160, the pair of humidifying members 160 may be rotated at the same time, or one of the two, so that the humidifying member 160 is positioned at the third position. It is also possible to rotate only the humidifying member 160.

Next, with reference to FIGS. 10 to 16, the humidifier purifier 100 according to the second embodiment of the present invention will be described.

FIGS. 15 and 16 are humidifying members 160 shown in FIG. It is a perspective view showing various modifications of the.

10 and 11, the humidifier purifier 100 according to the second embodiment of the present invention includes a housing 100 having an inlet 111 and an outlet 112, and an interior of the housing 110. It is provided with an air purification filter 120 for filtering the air flowing from the suction port 111, and a blowing unit 130 for flowing the air flowing from the suction port 111 to the discharge port 112, and the blowing unit A humidification unit 150 provided at a rear end of the 130 and having a humidifying member 160 for humidifying the air discharged from the blowing unit 130, and a humidification adjustment unit 170 for rotating the humidification unit 150 ), it is determined whether the air filtered through the air purifying filter 120 is humidified according to the position of the humidifying member 160 moved by the humidification adjusting unit 170.

The configuration of the housing 110, the air purification filter 120, and the blowing unit 130 provided in the humidifying purifier 100 according to the second embodiment of the present invention is described with reference to FIGS. 1 to 6 Since it is the same as the case, the detailed description will be replaced with the above-described contents, and the description will be made focusing on the configuration of the humidifying unit 150 and the humidifying adjustment unit 170 having differences.

The humidifying member 160 provided in the humidifying purifier 100 according to the second embodiment of the present invention at least part of the discharge flow path AF which is a flow space of air discharged from the blowing section 130 to the discharge port 112 side It has a structure that rotates about an axis Y parallel to the discharge flow path AF to open or block it. In addition, the humidification adjustment unit 170 rotates the humidifying member 160 around an axis (Y) parallel to the discharge flow path (AF), and the air purifying filter 120 according to the position of the humidifying member 160 Whether or not the filtered air is humidified is determined.

Then, the opening degree of the discharge flow path AF is changed according to the position of the humidifying member 150 moved by the humidifying adjustment unit 170, and the humidification amount of the filtered air through the air purification filter 120 can be adjusted. have.

10 to 12, the humidifying unit 150 may be provided at a rear end of the blowing unit 130 to be configured to humidify the air discharged from the blowing unit 130. That is, the humidification unit 150 may be installed in a space between the blowing unit 130 and the discharge port 112 to filter the air purification filter 120 and then humidify the air passing through the blowing unit 130.

As described above, when the humidifying unit 150 is provided at the rear end (that is, the upper portion) of the blowing unit 130, all the air that has passed through the air purification filter 120 flows into the blowing unit 130, and then the humidifying unit 150 Since it is introduced into the humidification performance can be improved.

The humidifying unit 150 may include a humidifying member 160 made of a hygroscopic material to perform humidification through vaporization of absorbed water, and a water tank 151 having a receiving space 152 in which water for humidification is accommodated. have. That is, the humidifying member 160 is immersed in a water tank to absorb water, and when the air flows through the blower 130, the absorbed water may be vaporized to be humidified.

In addition, the humidification unit 150 may further include a water tank 155 for supplying water to the water tank 151. Since the water supply structure between the water tank 151 and the water tank 155 is a technique widely used in a humidifier, detailed description will be omitted.

Meanwhile, referring to FIG. 12, the water tank 151 may have a ring shape in which an opening 153 through which air flows is formed in the center, and the humidifying member 160 may have a shape partially covering the opening 153. Can.

Referring to FIG. 12, the humidifying member 160 includes a humidifying filter 161 made of a hygroscopic material that absorbs water contained in the water tank 151, and a humidifying filter 161 to maintain the shape of the humidifying filter 161. A frame 165 installed on the outside may be provided. At this time, the frame 165 may be made of a material having a strength that can maintain the appearance of the humidifying filter 161, such as synthetic resin.

In addition, the humidifying filter 161 may have a shape consisting of a hollow cone or a portion of a cone, as shown in FIG. 12. For example, the humidification filter 161 may have a hollow truncated cone or a half cut in the vertical direction. Accordingly, as described later, when the humidifying filter 161 rotates around the rotation axis Y, the discharge passage AF or the outlet 142 of the pan casing 140 is opened or closed as a whole, or only partially opened Will be able to implement

In addition, the humidifying member 160 may be disposed on the upper portion of the blower 130 so that the lower side of the humidifying filter 161 is wide and the upper side is narrow, as shown in FIGS. 10 and 11.

In addition, the frame 165 has a structure supporting the periphery of the plate-shaped humidifying filter 161, and may have a grid 166 structure on the upper side. In addition, a humidification adjustment unit 170 may be installed above the frame 165 to rotate the frame 165 and the humidification filter 161.

However, the shape of the humidifying filter 161 is not limited to the shape shown in FIG. 12, and one end of the humidifying filter 161 is immersed in the water tank 151 to absorb water and partially cover the opening 153 If the humidification filter 161 can rotate around the rotation axis Y, various changes are possible. For example, the humidifying filter 161 may have a structure in which the upper part is inclined with respect to the rotation axis Y and the lower part may have a vertical structure parallel to the rotation axis Y. As another example, the humidifying filter 161 may have a structure in which the upper part is perpendicular to the rotation axis Y and the lower part is parallel to the rotation axis Y, that is, a'a' structure.

Meanwhile, the humidification adjustment unit 170 rotates the humidifying member 160 around an axis Y parallel to the discharge passage AF so that the humidifying member 160 opens or blocks at least a portion of the discharge passage AF. It is configured to. At this time, when the blowing unit 130 is provided with a fan casing 140, the discharge flow path AF corresponds to a space in which air flows from the outlet 142 of the fan casing 140 toward the discharge port of the housing 110. do.

The humidification adjustment unit 170 is configured to include a motor driven by the control unit (C) can be configured to rotate the humidifying member 160 around an axis (Y) parallel to the discharge flow path (AF), Depending on the location of the humidifying member 160, it may be determined whether to humidify the filtered air through the air purifying filter 120.

For example, the humidifier purifier 100 has a high-humidity clean mode in which air cleaning and maximum humidification are performed when the humidifying member 160 rotated by the humidifying adjusting unit 170 is in a position shown in FIGS. 10 and 11. When the humidifying member 160 is located in the position shown in FIG. 13, a clean-only mode in which humidification is not performed and only air cleaning is performed is performed, and the humidifying member 160 is positioned at the position shown in FIG. If present, a low-humidity clean mode in which air cleaning and some humidification can be performed.

That is, the opening degree of the discharge flow path AF is changed according to the position of the humidifying member 160 moved by the humidifying adjustment unit 170, filtered through the air purification filter 120, and then passed through the blowing unit 130. The humidification amount of air may be adjusted according to the position of the humidifying member 160.

13, 10 and 14, a high-humidity clean mode, a clean-only mode, and a low-humidity clean mode will be described in more detail.

As shown in FIG. 13, when the humidifying member 160 rotates around the axis Y and is in the first position, the humidifying member 160 completely opens the discharge flow path AF. Therefore, the air coming out of the outlet 142 after being filtered through the air cleaning filter 120 is discharged through the outlet 112 without going through the humidifying member 160, so a clean dedicated mode in which humidification is not performed is performed.

As shown in FIG. 10, when the humidifying member 160 rotates around the axis Y and is in the second position, the humidifying member 160 blocks at least a portion of the discharge flow path AF. Therefore, since most of the air coming out of the outlet 142 after being filtered through the air cleaning filter 120 passes through the humidifying member 160 and is discharged through the outlet 112, a high-humidity clean mode in which a large amount of humidification is achieved Is performed

As described above, the humidifying member 160 may be configured to be rotatable between a first position that opens the discharge flow path AF and a second position that blocks at least a portion of the discharge flow path AF, thereby allowing humidification. Performance can be determined.

Meanwhile, as shown in FIG. 14, the humidifying member 160 may have a third position between the first position and the second position. That is, the area in which the humidifying member 160 blocks the discharge passage AF in the third position is smaller than the area in which the discharge passage AF is blocked in the second position. Therefore, after filtering through the air cleaning filter 120, some of the air coming from the outlet 142 passes through the humidifying member 160 and is discharged through the outlet 112, and the rest of the air does not pass through the humidifying member 160. Since it is discharged directly through the discharge port 112, a low-humidity clean mode with less humidification is performed than in the case shown in FIG.

At this time, the control unit (C) drives the humidification adjustment unit 170 so that the humidifying member 160 is positioned at an arbitrary third position between the first position shown in FIG. 13 and the second position shown in FIG. 10. The member 160 can be rotated. Therefore, the control unit C can be made to humidify in accordance with the humidity in the air, it is also possible to adjust the amount of humidification by adjusting the rotation amount (rotation angle) of the humidifying member 160.

In addition, as shown in FIGS. 10(b), 13(b) and 14(b), the humidifying filter 161 of the humidifying member 160 is projected onto the outlet 142 of the pan casing 140. In this case, according to the position of the humidifying member 160, the humidifying member 160 changes the area covering the discharge flow path AF and the outlet 142 of the pan casing 140. For example, when the humidifying member 160 projects the humidifying filter 161 to the outlet 142 when the humidifying member 160 is in the third position, the area where the humidifying filter 161 covers the outlet 142 Has a value between the area when the humidifying member 160 is in the first position and the area when the humidifying member 160 is in the second position. Therefore, since the opening degree of the discharge flow path AF or the outlet 142 changes according to the position of the humidifying member 150 moved by the humidifying adjustment unit 170, air is adjusted by adjusting the rotational position of the humidifying member 160. Whether or not the humidification and the humidification amount of the filtered air through the purification filter 120 can be adjusted.

Meanwhile, since the humidifying member 160 illustrated in FIG. 12 has a grid space 166a formed between grids 166 provided on an upper side of the frame 165, air flowing out of the blower 130 is the grid space If discharged through (166a), loss of humidification may occur,

In consideration of this, as shown in FIG. 15, the humidifying member 160 is a flow restricting film 164 that restricts the flow of air in the upper region of the frame 165 corresponding to the portion where the humidifying filter 161 is installed. ) Can be installed.

In addition, as illustrated in FIG. 16, in order to prevent the air flowing out of the blowing unit 130 from being discharged through the side surface of the frame 165 where the humidification filter 161 is not installed, loss of humidification amount is generated, The humidifying member 160 may include a blocking film 163 that forms a closed space together with a humidifying filter 161 on a side portion of the frame 165 to limit air flow to the side. At this time, the lower portion of the blocking layer 163 may have a height that does not interfere with the water tank 151.

As described above, the humidifier purifier 100 according to the second embodiment of the present invention can implement a clean-only mode, a high-humidity clean mode, and a low-humidity clean mode through rotation of the humidifying member 160, so that the amount of dust and humidity It is possible to determine whether or not to humidify based on the humidification amount can be adjusted when the humidification is made. In particular, since the low-humidity clean mode shown in FIG. 14 can adjust the amount of humidification in various stages by adjusting the rotational position of the humidifying member 160, there is an advantage that fine adjustment of the amount of humidification is possible.

In addition, since the humidifying member 160 is installed at the rear end of the air cleaning filter 120 and the blowing unit 130 (that is, the upper part of the housing), in the case of a high-humidity clean mode, most of the air that has passed through the air cleaning filter 120 Since it flows into the humidifying unit 150 through the blowing unit 130, the humidifying performance may be improved. In addition, in the case of the clean-only mode, all air that has passed through the air purification filter 120 is discharged through the discharge port 112 without passing through the humidifying unit 150 through the blowing unit 130, thereby maximizing air cleaning efficiency. In particular, since the discharge flow path AF used in the clean exclusive mode is used as it is in the humid clean mode, it is advantageous in that the structure is simple since no dedicated flow path for humidification is required.

In addition, since a structure in which the humidifying member 160 is directly rotated is used to implement a high-humidity clean mode, a low-humidity clean mode, and a clean-only mode, a separate flow path changing means required in the prior art is not required.

In addition, since the humidifying unit 150 is located at the upper portion of the blowing unit 130, the air purifying filter, the humidifying unit, and the blowing unit can reduce the installation area compared to the conventional structure in which they are arranged in a straight line. In addition, since the humidifying filter 161 is located adjacent to the discharge port 112, it is possible to easily check and clean whether the humidifying filter 161 is contaminated, thereby improving hygiene.

Although the embodiments of the present invention have been described in detail above, the scope of rights of the present invention is not limited to this, and various modifications and variations are possible without departing from the technical spirit of the present invention as set forth in the claims. It will be obvious to those of ordinary skill in the field.
