Description

Air purifying system {Air purifying system}

The present invention relates to an air purifier and an air purification system.

An air purifier is a device that sucks in polluted air, purifies it, and then expels the purified air. For example, an air purifier may include a blower for drawing outside air into the interior of the air purifier, and a filter that can filter out dust or bacteria in the air. In general, air purifiers are configured to purify indoor spaces such as homes or offices.

The above air purifiers are mass-produced in predetermined specifications and sizes according to a set design and supplied to the market. Consumers select and purchase air purifiers that match their desired size and capacity. Consumers have difficulty purchasing air purifiers that are suitable for their living environments due to the existence of multiple partitioned indoor spaces and irregular shapes of indoor spaces in their living environments.

To solve this problem, WO2017/026761A1 discloses a technology for an air purifier that can vary the intake and discharge of air based on a deformable filter. This technology can implement an air purifier that corresponds to the capacity of the current indoor space by deforming the filter in response to the installation environment of the air purifier.

According to the above technology, it is difficult for the user to know what shape the filter should be implemented in, and the user must modify the filter himself. In addition, even if the air purifier filter is modified, the inconvenience of only being able to purify the air in a certain space remains.

WO2017/026761A1 Air Purifier

The present invention is proposed under the above background, and proposes an air purifier and an air purification system that allows consumers to appropriately operate the air purifier in various spaces appropriately configured to suit their living environment by using a single air purification system.

The present invention proposes an air purifier and air purification system capable of appropriately purifying the air in a required space by simply moving and operating individual elements to required locations without the user having to operate them.

The present invention proposes an air purifier and air purification system capable of responding to the physical needs of an installation space, personal needs, and environmental needs.

The air purification system according to the present invention comprises at least three air purifiers capable of operating independently; and a support frame for supporting the at least three air purifiers. Accordingly, since each air purifier can be separated or assembled, the air purification system can be operated in various states desired by the user.

The above-mentioned placement frame includes a backbone extending in an up-down direction; and a support extending forward from the bottom of the backbone. Accordingly, the air purifier can be conveniently handled by placing it on the support.

The at least three air purifiers may include a first stage air purifier placed on the stand; a second stage air purifier fixed to the backbone above the first stage air purifier; and a third stage air purifier supported on the upper surface of the second stage air purifier.

Accordingly, the second stage air purifier, which is a main unit of a larger size, can blow clean air to the entire area of the indoor space. The first stage air purifier moves forward and is separated from the frame, and the third stage air purifier moves upward and is separated from the frame, so that there is an advantage in that it is convenient for the user to handle.

The bottom surface of at least one of the three air purifiers can serve as a flow guide for the clean air discharged from at least one other of the three air purifiers. Accordingly, the three air purifiers can be provided in a concentrated manner to increase space utilization. In addition, a side cleaning area can be provided on the immediate side of the air purification system to enhance user satisfaction.

The above-mentioned stand is provided with a fixing groove that extends forward and backward to guide the movement of the first stage air purifier, thereby facilitating the separation and installation of the air purifier.

The above-mentioned placement frame is inclined at a certain angle inwardly of the above-mentioned stand, thereby preventing the air purification system from tipping over due to its own weight, preventing the air purifier from falling when placed, and increasing the shock absorption capacity.

At least one of the above three air purifiers may be provided with a circular horizontal cross-section, and the horizontal cross-section may become smaller as it goes upward. Accordingly, the center of gravity of the air purifiers stacked vertically may be kept as low as possible, thereby greatly improving the safety of the air purification system.

The air purification capacity of the second stage air purifier is the largest, and the air purification capacity of the third stage air purifier is the smallest, so that the air purification system can be operated according to various capacities of indoor spaces. For example, the ratio of the air purification capacities of the first, second, and third stage air purifiers can be preferably set to 8:15:5. This can be suitably used in the order of the living room, bedroom, and kitchen.

An air purifier according to another aspect of the present invention comprises: a case accommodating a fan and a filter therein; a base provided on a lower side of the case; and a flow guide provided on the base, which extends upward from the center of the base outward and is convexly bent upward. Accordingly, clean air flowing axially from below can be guided radially, thereby providing a lateral clean area.

The above base is provided in a circular shape so that the air discharged upward from another air purifier on the lower side can be smoothly guided radially.

An air purification system according to another aspect of the present invention may include at least two air purifiers capable of operating independently; and a frame supporting the at least two air purifiers. Accordingly, an air purification operation can be actively performed for a partitioned indoor space, and through this, even if a single air purification system is used, a function equivalent to actually using two or more air purifiers can be performed.

The above-mentioned frame includes a backbone extending vertically; and a support supporting the backbone, so as to serve as a hub for each air purifier.

The at least two air purifiers include a first air purifier fixed to the frame; and a second air purifier detachable from the frame. Accordingly, by providing different types of air purifiers that can be fixed to or detached from the frame, an active air purification action can be performed on an indoor space that is partitioned in a more diverse manner.

The above at least two air purifiers can perform air purification function corresponding to the volume of a plurality of indoor spaces by providing different air purification capacities.

The above second air purifier is placed below the above first air purifier and is provided as a structure spaced vertically, so that a narrow indoor space can be used more smoothly, and when combined, a stronger air purification effect can be achieved.

In this case, a fixing groove may be provided on the stand so that the second air purifier is allowed to move forward and backward of the backbone. By doing so, the user's visibility of the fixing position can be improved, and the second air purifier can be placed in the correct position. In addition, the connection between the placement frame and the second air purifier can be stably performed.

The above second air purifier is placed above the above first air purifier and is provided as a structure spaced vertically, so that a narrow indoor space can be used more smoothly, and when combined, it can perform a stronger air purification function.

In this case, a fixing groove provided at the top of the first air purifier; and a fixing projection provided at the bottom of the second air purifier to correspond to the fixing groove may be included. Accordingly, the second air purifier can be stably positioned by the fitting action, and can be prevented from falling or tipping over.

In this case, the fixing groove is provided on the edge of the display housing on which the display is placed, so that the second air purifier can be stably supported.

The above first air purifier can be provided with a larger air purification capacity than the above second air purifier. Accordingly, air purification can be performed preferentially for the first indoor space where the frame is placed. In addition, when performing the air purification operation, air purification can be performed simultaneously for the first indoor space and the second indoor space which is partitioned from the first indoor space and is narrower than the first indoor space.

According to the present invention, at least two air purifiers suitable for each of a plurality of indoor spaces are integrated into a single air purification system. Accordingly, clean air can be supplied appropriately to each of the plurality of indoor spaces simultaneously.

According to the present invention, a plurality of air purifiers can be stably supported on a single frame. This makes it convenient to use and handle the air purification system.

According to the present invention, the individual air purifier can be conveniently moved and placed in a state of being charged with energy. Accordingly, the user can perform optimal air purification operation by simply carrying the air purifier of the desired capacity and moving it to the required location and operating it. Of course, if a separate power connection line is provided for the individual air purifier, it can be operated for a long period of time even when separated from the station.

According to the present invention, a plurality of individual air purifiers can be used together or for special purposes, thereby providing a wider range of air purification operations. As a result, the air purification system can be used to optimally respond to a wider range of consumer needs.

According to the present invention, for a plurality of indoor spaces divided into various sections, an optimal air purification function can be performed for any space that is merged with each other and includes at least one of the indoor spaces.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings. However, the idea of the present invention is not limited to the embodiments presented below, and those skilled in the art who understand the idea of the present invention will be able to easily propose other embodiments included within the scope of the same idea by adding, changing, deleting, and adding components, but this can also be said to be included within the scope of the idea of the present invention.

In the description below, the air purification system comprises at least two air purifiers capable of being operated individually and cooperatively in a single space.

In this case, the air purification system may be integrated with at least two air purifiers capable of being operated individually by another element. The air purification system may be integrated with at least one air purifier capable of being operated individually by another element.

Here, the air purification system is configured such that at least two air purifiers capable of individual operation are separated and can be operated individually in different environments.

In the following description, if a number such as one or two or three is indicated, it may be interpreted to include a greater number provided, unless otherwise specified.

In the following description, the standard for direction is the front of the air purification system that users mainly approach, and other direction indications are also based on users facing the front of the air purification system.

Figure 1 is a front perspective view of an air purification system according to an embodiment.

Referring to FIG. 1, an air purification system according to an embodiment includes three air purifiers (1), (2), and (3) capable of independently operating, and a frame (7) for positioning the three air purifiers (1), (2), and (3) together. The three air purifiers (1), (2), and (3) can move to various locations in an indoor space, but the frame (7) allows the movement of the air purifiers while restricting its own movement or movement.

Here, the meaning of restricted movement can be judged by whether or not the user can conveniently move it by himself when he wants. For example, the weight of the above-mentioned placement frame (7), or the combined weight of the above-mentioned placement frame (7) and one air purifier fixed to the above-mentioned placement frame (7), is on the order of several kilograms to several tens of kilograms, and the user cannot easily lift and move it. Therefore, it can be said that the movement is restricted. In contrast, at least one of the above-mentioned three air purifiers (1), (2), and (3) weighs less than several kilograms, and the user can lift and move it lightly. Therefore, it can be said that the movement is not restricted.

The above-mentioned placement frame (7) includes a backbone (8) extending vertically from the rear center portion, a first stage support (4) extending forward from the bottom portion of the backbone (8), a second stage support (5) positioned on the upper side spaced apart from the first stage support (4) and extending forward from the backbone (8), and a third stage support (6) positioned on the upper side spaced apart from the second stage support (5) and extending forward from the backbone (8).

Each of the above air purifiers (1)(2)(3) may be provided with a circular horizontal cross-section to correspond to the flow and discharge of clean air and to efficiently use the internal space of the air purifier. Each of the above stands (4)(5)(6) may be provided with a circular horizontal cross-section frame corresponding to the shape of each of the above air purifiers (1)(2)(3).

On the upper surface of each of the above-mentioned stands (4)(5)(6), an air purifier (1)(2)(3) having the same number of stages as each stage can be placed. Each of the above-mentioned air purifiers (1)(2)(3) can be separated from each of the above-mentioned stands (4)(5)(6) and used individually in different locations.

In the above description, it is described that the second stage air purifier (2) is placed on the second stage support (5) and supported as a separate item. However, the present invention is not limited thereto, and the second stage support (5) and the second stage air purifier (2) may be integrated. The second stage support (5) and the second stage air purifier (2) may further be integrated with the frame (7). At least one of the second stage support (5) and the second stage air purifier (2) may be integrated with the backbone (8).

Since the above second stage air purifier (2) becomes one with the above frame (7), fixed air purification can be performed for the space where the frame (7) is placed. Considering that the frame (7) is an item that is difficult to move, the frame (7) and the second stage air purifier (2) can be placed in the living room. In this case, air purification can be smoothly performed for the living room as the user's main use space.

In the case where the above second stage air purifier (2) is integrated with the above backbone (8), the center of gravity of the air purification system according to the embodiment is formed at the top, which increases the risk of overturning when subjected to external impact. This problem is most severe in the case of the above third stage air purifier (3).

As a way to solve this problem, the air purification system according to the embodiment is provided such that the backbone (8) is inclined toward the center of the first support (1). More precisely, the backbone (8) is provided such that it is inclined inwardly toward the central axis of the air purification system as it goes upward, that is, toward the center. Through this, the center of gravity of the second air purifier (2) and the frame (7) can be made to be directed more toward the center of the air purification system. In other words, even if the air purification system is inclined, the amount of movement of the center of gravity is small, and the frame (7) may not fall over.

The more the center of gravity of the above air purification system is centered, the less shaking there is and the faster recovery is achieved when an external impact is applied to the above air purification system. As a result, not only is the overturning of the above-mentioned placement frame (7) prevented, but in particular, the overturning of the above-mentioned third-stage air purifier (3) can be prevented.

The above first, second, and third stage air purifiers (1), (2), and (3) may have a horizontal cross-sectional area that becomes narrower as they go upward. Through this, the center of gravity of the placement frame (7) may move downward. As the center of gravity of the air purification system moves downward, the air purification system shakes less and recovers faster when subjected to an external impact. As a result, the air purification system including the placement frame (7) may be prevented from falling over. In particular, since the third stage air purifier (3) does not shake significantly and recovers quickly due to an external impact, the third stage air purifier (3) may be prevented from falling over.

The above first stage support (4) is provided as a solid base frame and can support the entire load of the air purification system according to the embodiment.

The above first stage air purifier (1) may have a smaller air purification capacity than the second stage air purifier (2) and a larger air purification capacity than the third stage air purifier (3). The ratio of the air purification capacities of the first, second, and third stage air purifiers (1) may be preferably set to 8:15:5.

In this case, the first stage air purifier (1) can be suitably used in a space such as a bedroom, the second stage air purifier (2) in a living room, and the third stage air purifier (3) in a study room or kitchen. In other words, the living room is the largest space, and the bedroom is a smaller space than the living room. Finally, the study room and the kitchen are spaces for performing special purposes assigned to each indoor space. For example, the third stage air purifier (3) can be placed next to a heating appliance to purify smoke generated from food being cooked. Of course, at this time, the third stage air purifier (3) can be separated from the frame (7) and moved.

Figure 2 is a drawing explaining the separation method of each of the above air purifiers.

Referring to Fig. 2, the second stage air purifier (2) is provided as one body with the frame (7), and can have the largest load among the air purifiers (1), (2), and (3).

The above first stage air cleaner (1) can be mounted on the first stage support (4) of the placement frame (7) by sliding backward along a settling groove (294) that is sunken down from the support and extends forward and backward. The first stage air cleaner (1) can be separated by moving forward from the first stage support (4).

The above third stage air purifier (3) can be moved downward and mounted on the third stage support (6) of the frame (7). The separation of the third stage air purifier (3) can be performed by moving upward from the third stage support (6).

When the first and third stage air purifiers (1)(3) are mounted on each stand (4)(6), the mounting frame (7) and each air purifier (1)(3) are connected so that communication can be performed between the air purifier and the mounting frame. When the first and third stage air purifiers (1)(3) are mounted on each stand (5)(6), energy can be supplied from the mounting frame (7) to each air purifier (1)(3). The power supply from the mounting frame (7) to each air purifier (1)(3) can be applied by at least one of wired charging and wireless charging.

The above first, second and third stage air purifiers (1) may have a fan and a filter inside. The fan provides negative pressure. By the negative pressure, air can be sucked in through one side of the air purifier to filter out foreign substances, and clean air can be discharged through the other side.

One side of the air purifier that takes in outside air can be the side of the air purifier, and the other side of the air purifier that discharges clean air filtered of foreign substances can be the top of the air purifier.

Fig. 3 is a cross-sectional view taken along line A-A' of Fig. 2 showing the internal configuration of an air purifier according to an embodiment, and Fig. 4 is an exploded perspective view of a configuration directly related to a blower and a filter of an air purifier according to an embodiment. Fig. 4 can be understood as a state in which the case (101) and the display (191) of Fig. 3 are removed.

The internal configuration of the air purifier can be applied similarly to each air purifier (1), (2), and (3). The size and length of each component placed inside each air purifier, top and bottom, left and right, etc. can be different. The external shape of the air purifier can be different for the positioning of the air purifier or the air purification capacity, etc.

In the embodiment, the second stage air purifier (2) is used as an example to explain. In the case where the first and third stage air purifiers (1) and (3) differ from the second stage air purifier (2), a special explanation is added.

In the embodiment, the configuration of each air purifier is similar to each other, so it is described using the same number. If it is necessary to explain which air purifier the configuration is, the corresponding single air purifier is presented, and then the number of the component is used to describe it.

Referring to FIGS. 3 and 4, the air purifier (2) according to the embodiment can generate air flow. In this case, the air flow can be understood as sucking in indoor air at the bottom of the air purifier (2) and discharging it upward.

The above air purifier (2) includes a case (101) forming an exterior. The case (101) may be provided in a cylindrical shape. The above air purifier (2) may be called an air purification module in that it has a filter and performs the function of purifying air.

The case (101) may include a separation part (not shown) in which two parts constituting the case (101) are combined or separated. The case (101) may further include a hinge part (not shown) provided on the opposite side of the separation part. The two parts may rotate relative to each other around the hinge part. Therefore, when at least one of the two parts rotates, the case (101) can be opened and separated from the air purifier (2). By opening the case (101), the internal components of the blower (100) can be replaced or repaired.

A case-side suction part (102) through which air is sucked is formed at the bottom of the case (101). The case-side suction part (102) may be provided as a through hole formed by penetrating at least a portion of the case (101). A plurality of through holes forming the case-side suction part (102) are formed.

The above-described plurality of case-side suction portions (102) can be evenly formed in a circumferential direction along the outer surface of the case (101) so that air can be sucked in from any direction based on the case (101). That is, air can be sucked in from a direction of substantially 360 degrees based on the vertical center line passing through the inner center of the case (101).

Since the case (101) is configured in a cylindrical shape and a plurality of case-side suction portions (102) are formed along the outer surface of the case (101), the amount of air suction can increase. The air sucked through the case-side suction portions (102) can flow approximately in a radial direction from the outer surface of the case (101).

Based on Figure 3, the up-down direction can be called the axial direction, and the horizontal direction can be called the radial direction.

The above axial direction may correspond to the central axis direction of the fan (160), i.e., the motor axis direction of the fan. The above radial direction may be understood as a direction perpendicular to the above axial direction. The direction of a virtual circle formed when rotating with the above axial direction as the center and the distance in the above radial direction as the radius of rotation may be referred to as a circumferential direction.

The above air purifier (2) may include a base (20) provided on the lower side of the case (101) and placed on the floor. The base (20) may be positioned spaced downward from the lower end of the case (101). A base-side suction part (103) may be formed in the space between the case (101) and the base (20).

Air sucked in through the above base side suction part (103) can flow upward through the suction port (112) of the suction grill (110) provided on the upper side of the base (20).

The above air purifier (2) may include a plurality of suction parts (102)(103). Air existing in the lower part of the indoor space can be easily introduced into the air purifier (2) through the plurality of suction parts (102)(103). Accordingly, the amount of air suction can be secured.

A discharge portion (105) may be formed at the upper portion of the air purifier (2). Air discharged through the discharge portion (105) flows axially upward. Clean air discharged through the discharge portion (105) may be spread radially by a discharge grill (192) located downstream of the discharge portion (105), that is, above the discharge portion (105). The discharge grill (192) is provided in a spiral shape, so that clean air discharged through the discharge portion (105) may also have a component that is spread circumferentially by the discharge grill (192).

The above discharge portion (105) and the above discharge grill (192) can be collectively referred to as a discharge guide device (190).

The air purifier (2) may further include a suction grill (110) arranged on the upper side of the base (20). The base (20) may include a base body (21) placed on the floor and a base protrusion (22) protruding upward from the base body (21) and on which the suction grill (110) is placed. A base suction part (103) forming an air suction space may be provided between the base (20) and the suction grill (110).

Below the base body (21), a flow guide (23) is provided, and a base bottom surface (24) is provided at the bottom of the flow guide. The cross section of the flow guide (23) extends upward from the center outward and is convexly bent upward. The flow guide (23) may be provided in the same shape in the radial direction.

The above-mentioned flow guide (23) can guide the air discharged from the first stage air purifier (1) placed on its lower side in a radial direction. That is, the bottom surface of the upper air purifier among the two air purifiers that are stacked can provide a flow guide for the discharged air of the lower air purifier.

The above suction grill (110) may include a grill body (111) having a roughly ring shape and suction ports (112) formed on the edge of the grill body (111). The suction ports (112) may be provided in multiple numbers spaced apart along the edge. The multiple suction ports (112) may be connected to the base-side suction portion (103).

The above air purifier (2) may further include a filter member (120) that is placed above the suction grill (110) and filters air.

Air sucked through the above suction port (112) and the base side suction portion (103) can pass through the filter member (120). The air can penetrate the outer surface of the cylindrical filter member (120) and flow into its interior. The filter member (120) can be provided in a cylindrical shape and have a filter surface that filters air.

The above suction grill (110) may further include a lever support portion (113) that forms the upper surface of the grill body (111) and supports the lever device (142), and a groove portion (114) that is formed by being sunken inwardly in the radial direction from the outer surface of the grill body (111). The groove portion (114) may provide a space in which the handle (144) can move.

The above air purifier (2) is provided with a lever device (142) that is provided on the upper side of the suction grill (110) and can be operated by the user. The lever device (142) may include a lever body (143) that has a substantially ring shape and is provided to be rotatable.

The lever body (143) may include a lever protrusion (145) provided on the edge of the lever body (143). The lever protrusion (145) protrudes upward from the upper surface of the edge of the lever body (143), and may be provided in multiple numbers spaced apart from each other. The multiple lever protrusions (145) may be understood as having a configuration having an inclined surface in order to move the support device (140) described below upward or downward.

A handle (144) is provided on the outer surface of the lever body (143). A user can hold the handle (144) and rotate the lever body (143) clockwise or counterclockwise.

The air purifier (2) may further include a support device (140) that supports the filter member (120) on the upper side of the lever device (142). The lever device (142) supports the lower surface of the support device (140). The support device (140) may be provided with a support protrusion (not shown) that comes into contact with the lever protrusion (145). The support protrusion may protrude downward from the lower surface of the support device (140) and may be provided in a number corresponding to the lever protrusion (145). The support protrusion may include an inclined surface.

During the process of rotating the lever body (143), the lever protrusion (145) can rotate together with the lever body (143). At this time, when the upper part of the lever protrusion (145) comes into contact with the lower part of the support protrusion, the lever body (143) pushes the support device (140) upward. When the support device (140) moves upward, the filter member (120) is coupled to the air purifier (2).

On the other hand, when the lower part of the lever protrusion (145) comes into contact with the upper part of the support protrusion, the support device (140) moves downward. When the support device (140) moves downward, the filter member (120) is in a state (released state) in which it can be separated from the air purifier (2).

The above air purifier (2) may further include a filter frame (130) that forms a mounting space for the filter member (120). The filter frame (130) may include a first frame (131) that forms a lower portion of the filter frame (130) and a second frame (132) that forms an upper portion of the filter frame (130).

The first frame (131) may have a ring shape with a portion thereof cut off. The ring-shaped internal space of the first frame (131) may form at least a portion of an air passage passing through the filter frame (130).

On the inner surface of the first frame (131), the lever device (142) and the support device (140) may be positioned. The upper surface of the support device (140) may include a mounting surface on which the filter member (120) is placed. A handle space portion (131a) that allows the handle (144) of the lever device (142) to be operated may be provided in a portion of the cut-out space of the first frame (131).

The above handle (144) is located in the handle space (131a) and can be operated clockwise or counterclockwise.

The second frame (132) may be positioned spaced upward from the first frame (131). The second frame (132) has an approximately ring shape. The ring-shaped internal space of the second frame (132) may form at least a portion of an air passage passing through the filter frame (130). The upper portion of the second frame (132) may support a fan housing (150) to be described later.

The filter frame (130) may further include a filter support member (135) extending upward from the first frame (131) toward the second frame (132). By the filter support member (135), the first and second frames (131) (132) may be spaced apart from each other. The filter support members (135) are provided in multiple numbers, and the multiple filter support members (135) may be arranged in a circumferential direction and connected to the edges of the first and second frames (131) (132).

The mounting space of the filter member (120) can be defined by the first and second frames (131)(132) and the plurality of filter support members (135).

In the above-mentioned mounting space, the filter member (120) can be detachably mounted. The filter member (120) has a cylindrical shape, and air can be introduced through the outer peripheral surface of the filter member (120). In the process of passing through the filter member (120), impurities such as fine dust in the air can be filtered out.

Since the above filter member (120) has a cylindrical shape, air can be introduced from any direction based on the above filter member (120). Accordingly, the air filtering area can be increased.

The above-mentioned mounting space may be provided in a cylindrical shape corresponding to the shape of the filter member (120). The filter member (120) may be slidably introduced toward the mounting space during the mounting process. Conversely, the filter member (120) may be slidably withdrawn from the mounting space during the dismounting process.

The case where the above filter member is separated will be described. When the handle (144) is operated while the above filter member (120) is placed on the upper surface of the above support device (140), the above filter member (120) moves downward and is in the released position. The above filter member (120) slides radially outward and can be separated from the above mounting space.

The case where the above filter member is mounted will be described. The filter member (120) can be slid radially inward toward the mounting space and placed on the upper surface of the support device (140). The filter member (120) can be pressed upward by operating the handle (144) and placed in a combined position.

A support cover (136) can be attached to the outside of the above filter support (135).

The above air purifier (2) may include a blower (100) that provides air flow pressure so that air can be sucked into the suction port (102)(103). The blower (100) is arranged above the filter member (120) and can cause filtered air passing through the filter member (120) to flow upward.

The above blower (100) includes a fan housing (150) installed on the outlet side of the filter member (120). A fan (160) is accommodated in the fan housing (150). The fan housing (150) can be supported by the filter frame (130).

The lower part of the fan housing (150) includes a fan inlet (152) that guides the inflow of air into the interior of the fan housing (150). A grill is provided on the fan inlet (152), so that when the filter member (120) is separated, the user can prevent his or her fingers or the like from entering the interior of the fan housing (150).

A support rib (197) may be extended upward from the fan housing (150). A display housing (198) may be provided at the upper end of the support rib (197). The display housing (198) may display the operating status of the air purification system or each air purifier provided with a display.

A mounting groove (193) may be provided on the upper surface of the frame of the display housing (198). A mounting projection (see 194 of FIG. 8) of the third air cleaner (3) may be placed in the mounting groove (193). When the mounting projection (194) is placed in the mounting groove (193), the third-stage air cleaner (3) may be supported on the second-stage air cleaner (2). In addition to the lower end of the third-stage air cleaner (3) being supported on the second-stage air cleaner (2), the third-stage air cleaner (3) may not have any other support structure in relation to the mounting frame (7).

The above blower (100) may further include a fan (160) that provides air flow pressure through rotation. The fan (160) may be placed above the fan inlet (152). As the fan (160), a centrifugal fan that introduces air in the axial direction and discharges the air radially upward may be provided.

The fan (160) may include a hub (161) to which a rotation shaft of a fan motor (165), which is a centrifugal fan motor, is coupled, a shroud (162) arranged spaced apart from the hub (161), and a plurality of blades (163) arranged between the hub (161) and the shroud (162). The fan motor (165) may be coupled to the upper side of the fan (160).

The above hub (161) may have a bowl shape with a diameter that narrows as it goes downward. The hub (161) may include a shaft coupling portion to which the rotation shaft is coupled and a first blade coupling portion that extends upwardly and obliquely from the shaft coupling portion.

The above shroud (162) may include a lower portion in which a shroud intake port is formed to suck in air passing through the fan inlet portion (152), and a second blade joint extending upward from the lower portion.

One side of the blade (163) may be coupled to the first blade coupling portion of the hub (161), and the other side may be coupled to the second blade coupling portion of the shroud (162). The plurality of blades (163) may be arranged spaced apart from each other in the circumferential direction of the hub (161).

Air passing through the filter member (120) may flow upward and enter the fan housing (150) through the fan inlet (152). The air may flow in the axial direction of the fan (160) and be discharged through the blade (163). At this time, the edge of the blade may be extended to be inclined upwardly and outwardly relative to the axial direction in response to the direction of the air flow so that the discharged air may flow radially upward.

The blower (100) may further include an air guide device (170) coupled to the upper side of the fan (160) to guide the flow of air passing through the fan (160). The air guide device (170) may be located on the upper side of the fan housing (150). For example, the air guide device (170) may be laminated to have the same outer diameter as the fan housing (150) to guide the flow of air passing through the fan (160).

The above air guide device (170) may include an outer wall (171) having a cylindrical shape, and an inner wall (172) located on the inner side of the outer wall (171) and having a cylindrical shape. The outer wall (171) may be arranged to surround the inner wall (172). A first air path (172a) through which air flows may be formed between the inner surface of the outer wall (171) and the outer surface of the inner wall (172).

That is, the diameter of the outer wall (171) is larger than the diameter of the inner wall (172).

The diameter of the outer wall (171) can be understood as the outer diameter of the air guide device (170), and the diameter of the inner wall (172) can be understood as the inner diameter of the air guide device (170).

The air guide device (170) may further include a motor receiving portion (173) that extends downward from the inner wall (172) and receives the fan motor (165). The motor receiving portion (173) may have a bowl shape with a diameter that becomes smaller as it goes downward. A motor coupling portion is provided on one side of the fan motor (165), and the motor coupling portion may guide the fan motor (165) to be fixed to the air guide device (170).

The shape of the above motor receiving portion (173) may correspond to the shape of the hub (161). In addition, the motor receiving portion (173) may be inserted into the inside of the hub (161).

The fan motor (165) may be supported on the upper side of the motor receiving portion (173). The rotational shaft of the fan motor (165) may extend downward from the fan motor (165) and may penetrate the bottom surface of the motor receiving portion (173) and be coupled to the shaft coupling portion of the hub (161).

The above air guide device (170) may further include a guide vane (175) arranged in the first air path (172a). The guide vane (175) extends from the outer surface of the inner wall (172) to the inner surface of the outer wall (171). A plurality of the guide vanes (175) may be arranged spaced apart from each other.

The above-described plurality of guide vanes (175) can perform the function of guiding upward the air that has entered the first air path (172a) of the air guide device (170) through the fan (160).

The above guide vane (175) may extend obliquely upward from the lower portion of the outer wall (171) and the inner wall (172). For example, the guide vane (175) may be formed in a round shape to guide air to flow obliquely upward.

Figures 5 to 7 are drawings showing preferred examples of use of each air purifier. Figure 5 is a drawing showing a preferred example of use of a second-stage air purifier (2), Figure 6 is a drawing showing a preferred example of use of a first-stage air purifier (1), and Figure 7 is a drawing showing a preferred example of use of a third-stage air purifier (3).

Referring to FIGS. 5 to 7, preferred usage examples of each air purifier will be described. As has already been described, the ratio of air purification capacities of the first, second, and third stage air purifiers (1), (2), and (3) can be preferably set to 8:15:5.

Among the above first, second, and third stage air purifiers (1), (2), and (3), the second stage air purifier (2) is an air purifier that is difficult to move because it is provided as one body with the frame (7). By using this, it can be preferably applied to the living room, which is the largest among general indoor spaces. For this purpose, the second stage air purifier (2) can be provided as being the largest and heaviest compared to the other air purifiers (1) and (3).

The above first stage air purifier (1) is an air purifier placed at the very bottom, and can be provided with the largest horizontal cross-sectional area among the first, second, and third stage air purifiers (1), (2), and (3). In this case, an air purifier with a relatively large capacity can be provided. Considering that among general indoor spaces, a bedroom can occupy the largest indoor space, excluding a living room, the above first stage air purifier (1) can be preferably applied to a bedroom.

When the above first stage air cleaner (1) is used, it may be used separated from the mounting frame (7). In order to enable operation while the first stage air cleaner (1) is separated, a charging means may be provided between the mounting frame (7) and the first stage air cleaner (1). A battery may be provided in the first stage air cleaner (1). Of course, if a power supply means such as a plug is provided in the first stage air cleaner (1), it may be operated for a long time in the separated state.

The above third stage air purifier (3) is an air purifier placed at the very top, and may have the smallest horizontal cross-sectional area among the first, second, and third stage air purifiers (1), (2), and (3). In this case, an air purifier with a relatively small capacity can be provided.

Since the above-mentioned third-stage air purifier (3) has the smallest air purification capacity, it can be preferably applied to special-purpose spaces such as study rooms and kitchens among general indoor spaces.

When the above-mentioned third stage air purifier (1) is used, it may be used separately from the upper surface of the above-mentioned second stage air purifier (2). In order to be used separately, a charging means may be provided between the above-mentioned second stage air purifier (2) and the above-mentioned third stage air purifier (3). A battery may be provided in the above-mentioned third stage air purifier (3). Of course, if a power supply means such as a plug is provided in the above-mentioned third stage air purifier (3), it may be operated for a long time in a separated state.

As a small-capacity air purifier, the third-stage air purifier (3) is provided in a small size and weight so that the user can easily move and use it.

In order to maintain the posture of the third stage air purifier (3) even when it is placed on the frame (7) in order to prevent external impact, the fixing projection (194) and the fixing groove (193) can be maintained in a state where they are fitted together. The fixing projection (194) and the fixing groove (193) can be fitted together in the vertical direction so that there is no problem in separating the third stage air purifier (3). Heavy parts can be placed in the center and bottom of the third stage air purifier (3) so that the center of gravity is guided to the center and bottom, thereby preventing overturning.

Fig. 8 is a cross-sectional view taken along line B-B' of Fig. 5, and shows a schematic structure of the above-mentioned placement frame. Regarding the internal structure and internal function of each air purifier in Fig. 8, the explanations of Figs. 3 and 4 can be applied to each air purifier as is.

Referring to Fig. 8, the external structure and external operation of the first, second, and third stage air purifiers (1), (2), and (3) and the frame (7) are described in detail.

Referring to Fig. 8, the placement frame (7) is provided with the first stage support (4), which serves as a bottom plate that supports the first stage air purifier (1) and prevents the placement frame (7) from falling over, and a backbone (8) that extends upward from the rear end of the first stage support (4). The first stage support (4) may be provided in a circular plane.

The above backbone (8) serves as a skeleton that supports the load of the second and third stage air purifiers (2)(3). The above backbone (8) is provided in a bar shape that is long vertically, and a solid material such as a resin material, a painted iron frame, or wood that accommodates an iron frame inside can be used.

The above backbone (8) can be tilted at a certain angle (α) toward the center of the first stage support (4) as it goes upward. As explained above, the center of gravity of the air purification system is moved to the center by this inclined structure, thereby preventing the topple of the placement frame (7).

The above second stage support (4) may be provided as one body with the second stage air purifier (2) and the backbone (8). In one aspect, the second stage support (5) may correspond to a configuration in which the lower part of the second stage air purifier (2) and the backbone (8) are connected as one body.

At the bottom of the second stage air purifier (2), a base (20) having a flow guide (23) is provided. The center of the flow guide (23) can correspond to the center of the discharge grill (192) of the first stage air purifier (2) below it by being spaced apart from each other vertically. The air discharged from the discharge grill (192) can be guided by the flow guide (23) and then discharged laterally of the air purification system. The clean air discharged laterally can provide a lateral cleaning area to an adjacent space of the air purification system.

According to the above configuration, it can be understood that a pair of air purifiers that are aligned vertically and can be separated from each other are provided, and the bottom surface of the upper air purifier serves as a flow guide that guides the clean air discharged from the lower air purifier laterally. According to this configuration, the configuration of an air purification system in which at least two or more air purifiers are used in combination can be provided in a slimmer and simpler manner.

A fixing groove (294) may be provided on the bottom surface of the first stage support (4). The fixing groove (294) is configured to allow the insertion guide (195) of the first stage air purifier (1) to be inserted. The first stage air purifier (1) can be placed in the correct position by the guiding action of the insertion guide (195) and the fixing groove (294).

At the top of the second stage air purifier (2), a display housing (198) that accommodates a display (191) therein may be provided. The display housing (198) may have its load supported by a support rib (197) extending from the pen housing (150). The display housing (198) may be connected to the pen housing (150) to have greater structural strength. The display housing (198) may support the weight of the display as well as the load of the third stage air purifier (3).

The edge of the display housing (198) may be placed corresponding to the edge of the euro guide (23) of the third stage air purifier (3). Specifically, an upper opening mounting groove (193) may be provided on the edge of the display housing (198), and an anchoring projection (194) extending downward from the lower edge of the euro guide (23) may be provided. The anchoring groove (193) and the anchoring projection (194) may be fitted into each other.

Finally, the third stage air purifier (3) can be placed on the second stage air purifier (2) so that its load can be supported. Accordingly, the upper part of the second stage air purifier (2) can also perform the role of the third support (6).

The second stage air purifier (2) can support the dead weight of the third stage air purifier (3) by itself. The dead weight of the third stage air purifier (3) can be connected to the frame of the second stage air purifier (2) through the display housing (198), the support rib (197), and the pen housing (150) provided to the second stage air purifier (2). The frame of the second stage air purifier (2) can be connected to the backbone (8). The backbone (8) can also support the dead weight of the second stage air purifier (2) through the case (101).

By means of the above-mentioned support structure, the self-weight of the three-stage air purifier (3) can be supported by the second-stage air purifier (2) without a separate structure for supporting the backbone. In other words, the self-weight of the third-stage air purifier (3) can be supported by the second-stage air purifier (2).

Figures 9 and 10 are drawings explaining the connection relationship between the backbone and the second stage air purifier.

Referring to Fig. 9, the first and second fastening members (801) (802) protruding from the upper and lower ends of the backbone (8) corresponding to the installation height of the second air purifier (2) can be fastened to the side of the second air purifier (2). The first and third stage air purifiers (1) (3) can be pulled out laterally and upwardly, respectively.

Referring to Fig. 10, the entire backbone (8) can be integrated with the side of the second stage air purifier (2).

In the case of the above-mentioned Fig. 9, the second stage air purifier (2) and the backbone (8) can be manufactured separately and then connected, making manufacturing convenient. However, since the structural strength may be reduced, it is necessary to provide the above-mentioned fastening members (801) (802) and the members connected thereto more firmly.

In the case of Fig. 10, the second stage air purifier (2) and the backbone (8) are integrated together, so that high structural strength can be obtained. However, considering the difficulty in manufacturing, a simple method such as insert injection may be applied.

Figure 11 is a drawing that more specifically explains the lateral cleaning area provided by the action of the above-mentioned euro guide.

The above-mentioned flow guide (23) has been described as changing the flow direction of the clean air discharged from the first stage air purifier (1) from the axial direction to the radial direction. In other words, the above-mentioned flow guide can guide a large amount of air discharged in the axial direction from the first stage air purifier (1) to the radial direction.

In Fig. 11, the arrows show the flow of the discharged air from the first stage air purifier (1). Referring to the arrows, the relatively large flow rate of clean air just before the discharged air from the first stage air purifier (1) is discharged is gathered together and blown to a specific area.

Since the above-mentioned specific area corresponds to the immediate lateral side of the first stage air purifier, it can be defined as a lateral cleaning area. The above-mentioned lateral cleaning area is indicated by a dotted line on the right side of the air purifier.

As described above, the discharge wind of the first stage air purifier (1) does not spread widely. In particular, it does not spread widely in the vertical direction. Therefore, the side cleaning area can be created in which the clean air is preferentially blown by concentrating on the immediate side of the first stage air purifier (1).

The diffusion cleaning area, which is in contrast to the above-mentioned lateral cleaning area, is indicated by a dotted line on the left side of the first-stage air cleaner. The above-mentioned diffusion cleaning area may mean an area that is affected by the clean air discharged from the first-stage air cleaner (1) when the flow guide (23) is absent. Since the first-stage air cleaner (1) has a strong axial flow rate of the discharged air, it is shown that it is more widely diffused in the up-down direction and left-right direction.

The above-mentioned lateral cleaning area can be provided in a space less than 50 centimeters from the floor that serves as a playground for children. Accordingly, it can be more preferably applied in cases where concentrated air cleaning is required for the adjacent location of the air cleaner, such as after returning home, when the capacity of the air cleaner is insufficient, or when the operation of the air cleaner has just begun.

According to the present invention, since a single air purification system provided with a plurality of air purifiers can perform various air purification functions corresponding to an indoor space, great industrial application is expected.
