Description

A multifunctional storage system including multiple fans

The present invention relates to a multifunctional storage system comprising a plurality of fans. Specifically, it relates to a multifunctional storage system for uniformly supplying external air to each of the plurality of fans when the plurality of fans are installed.

To remove contaminants or odors and to improve wrinkles by adding a separate mechanical device to the inside of a cabinet that can accommodate various items such as clothes, shoes, and blankets (aka 'clothing management' or 'clothing treatment') A variety of technologies are being developed. One of them is to use high-temperature humidified air that can absorb contaminants or odors on clothing.

Korean Patent Application Laid-Open No. 10-2018-0124746 by the present inventor proposes a multifunctional storage system capable of simultaneously performing an air cleaning function as well as a clothing management function to remove contaminants or odor substances such as clothes.

This multifunctional storage system includes a storage room and a machine room located below the storage room. A humidifier and a dehumidifier are provided in the machine room. When the outside air flows into the machine room, the outside air is heated by the heat generated by the dehumidifying unit and heated by the humidifying unit to generate high-temperature humidified air (referred to as 'naturally humidified air'), which flows into the storage room and places clothes, etc. Removes pollutants and odors. When the removal operation is completed, the dehumidifying unit operates to dehumidify the storage room.

In addition, since a filter is provided in the part of the machine room where the outside air is introduced, even if the operation to remove contaminants or odor substances such as clothes is not performed, the air cleaning operation can also be performed by filtering the introduced outside air from the filter and then exhausting it to the outside. can Such an air cleaning operation may be performed simultaneously with or separately from an operation for managing clothes and the like.

The size of such a multifunctional storage system is relatively large, similar to a general closet-type furniture, reaching about 180 cm. The storage room should be large enough to accommodate coats, and the machine room located under the storage room should include a fan to introduce and flow air, a filter to perform an air purification function, a water tank to replenish water for humidification, This is because it has to be sized so that various parts, such as a water tank, which are generated and discarded during dehumidification, can be mounted.

Moreover, in the structure in which the machine room is located at the bottom of the storage room, the natural humidified air only flows in and out through the lower opening inside the storage room, so a separate fan is needed at the top of the storage room to circulate the natural humidified air as a whole in the storage room, which Increase the overall height of the multifunctional storage system.

These factors make it difficult to develop a compact multifunctional storage system. There is also a prior art that omits most of the machine room and allows only simple air flow or ventilation, but in this case, it is possible to downsize, but the effect of removing pollutants or odorous substances such as clothes is reduced, and the air cleaning function can be performed. there is no

In order to solve this problem, in order to strengthen the air cleaning function and the clothes management function in the small multifunctional storage system, if a plurality of fans are used, the outside air can be sufficiently flowed.

However, when arranging a plurality of fans, there may be a difference in the location where the outside air is introduced due to the size of the small multifunctional storage system. Due to the difference in the position at which the outside air is introduced, a problem may occur that the amount of the outside air introduced into the plurality of fans varies.

There is a need for a method for uniformly supplying each of a plurality of fans in a small multifunctional storage system.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

Hereinafter, 'front part', 'front' or 'front' refers to the part or direction in which the door of the multifunctional storage system is located, and the part facing the user when using it and the direction toward it, and 'rear part', 'rear' Or 'rear' means the front part or the opposite part of the front part or its direction. However, it should be understood that this is for explanation and is included within the scope of the present invention even if there is a slight direction modification without departing from the concept of the present invention presented in the claims.

Hereinafter, 'circulating air' refers to the air introduced into the multifunctional storage system. When outdoor air flows into the multi-function storage system, it continues to circulate throughout the flow path including the storage room. At this time, the circulating air is circulating air. Some of the circulating air is exhausted to the outside as clean air, and the air before being exhausted is also referred to as circulating air.

1. Description of the concept and overall structure of the multifunctional storage system

First, in accordance with the present invention, a technical concept necessary for maintaining a function while miniaturizing a multifunctional storage system will be described.

The present invention proposes a multifunctional storage system in which outdoor air is directly introduced into the storage room 180, and the introduced outdoor air continues to circulate and flow through the circulation passage 400 located at the rear of the storage room 180. . That is, the storage room 180 is in communication with the circulation flow path 400 , where 'communication' is a concept including a connection in which each part directly contacts as well as a connection in which fluid communication is indirectly. For example, the inlet end of the circulation passage 400 communicates with the lower portion of the storage chamber 180 through the humidifying unit 200 , and the outlet end of the circulation passage 400 communicates with the variable passage module 500 through the variable passage module 500 . It communicates with the upper part of the storage room 180 .

For miniaturization, it is important that the circulation flow path 400 is located at the rear of the storage room 180 . One of the difficulties in miniaturizing the multifunctional storage system is the machine room located below the storage room 180 , and by changing the location of the machine room to the rear part of the storage room 180 , the height of the multifunctional storage system can be lowered. However, there may be some parts that cannot be changed to the rear part of the storage room 180 . For example, it is preferable that the water tank 210 of the humidifying unit 200 to which the user continuously replenishes water is located in the front part of the storage room 180 instead of the rear part. Also, a portion of the variable flow path module 500 , which is a passage through which circulating air flows into the storage room 180 , cannot be located at the rear of the storage room 180 due to its structure.

In addition, for miniaturization, the location of the flow path inlet 300 is also important. The shape of the storage chamber 180 is a shape in which the horizontal cross-sectional area thereof is narrowed downward, and the flow path inlet 300 is positioned in a space located between the outermost edge and the innermost edge of the storage chamber 180 . Through this, it is not necessary to secure a separate space for installing the flow path inlet 300 .

Specific details will be described below.

An outer surface and components of a multifunctional storage system according to the present invention will be schematically described with reference to FIGS. 1 and 2 .

The upper surface 110 is provided on the upper part of the multi-function accommodation system, and an exhaust grill 115 is located therein, so that part of the air circulating in the multi-function accommodation system or clean air filtered in the multi-function accommodation system is exhausted to the outside. The exhaust grill 115 is connected to an exhaust flow path 520 to be described later.

A side surface 120 is provided on each side of the multifunctional storage system, a rear surface 130 is provided on the rear part, and a base 140 is located below.

A door 150 is provided on the front of the multifunctional storage system. The door 150 may be opened and closed in a hinge manner, and an external material thereof may be a material that reflects light, such as a mirror, but is not limited thereto. An operation panel or a display (not shown) operated by a user may be located outside the door 150 .

The components of the multifunctional storage system according to the present invention will be schematically described with reference to FIGS. 3 to 5 . 3 and 4 , the illustration of the upper surface 110 , the side surface 120 , and the rear surface 130 is omitted for explanation.

A filter 151 for filtering outside air is provided under the door 150 provided on the front side of the multifunctional storage system. The filter door 152 is positioned inside the filter 151 , and the amount of filtered outside air can be controlled by controlling the degree of opening of the filter door 152 . For example, by blocking the filter door 152, outside air is not introduced and only internal circulation can be made continuously. The filter door 152 can be controlled differently according to various operating modes of the multifunctional storage system of the present invention, which will be described later.

When the door 150 is removed from the outside, the storage room 180 with one side open so that the user can access it is exposed. The flow guide 600 may be positioned on the inner upper surface of the storage room 180 , and the flow guide 600 has a portion for discharging circulating air into the storage room and a hanger 700 attached to the inside of the hanger (that is, It may include a portion for discharging circulating air (toward the mounted hanger lining). The flow guide 600 and the hanger 700 will be described later with reference to FIGS. 17 and 18 .

In one embodiment of the present invention, a separate lower filter 161 is located at the lower side of the door 150 to the front of the multifunctional storage system, so that outside air can be additionally introduced. The air introduced through the lower filter 161 may flow into the flow path inlet 300 to be described later without being introduced into the storage chamber 180 , or may flow together as circulating air through the storage chamber 180 . have.

The storage chamber filter 171 and the humidifier inlet 172 are positioned on the inner lower surface of the storage chamber 180 . The storage compartment filter 171 filters contaminants such as dust separated from the storage compartment 180 . The user can remove the storage compartment filter 171 and re-install it after cleaning. The humidifier inlet 172 is an opening through which the circulating air inside the storage chamber 180 is discharged to the outside of the storage chamber 180 , and is connected to the humidifier 200 . When pressure is formed in the flow path by the fan 420 to be described later, the air inside the storage chamber 180 is naturally directed to the humidifier 200 through the humidifier inlet 172 . The humidifier 200 will be described later with reference to FIGS. 10 to 12 .

The circulating air introduced into the humidifier 200 is humidified and flows into the flow path inlet 300 .

The circulation air introduced into the flow passage inlet 300 , that is, the humidified circulation air, flows into the circulation passage 400 . The circulation passage 400 is located at the rear of the storage room 180 , and includes a plurality of fans 420 that provide power for circulating and flowing air. In addition, a heating unit 450 is provided to heat the circulating air. In the example shown in FIGS. 4 and 5 , the circulation air rises along the circulation passage 400 .

The circulation air flowing in the circulation passage 400 reaches the variable passage module 500 . An exhaust passage 520 is branched from one side of the variable passage module 500 to exhaust some of the circulating air to the outside. One end of the variable flow passage module 500 is connected to the flow guide 600 so that circulating air flows into the storage chamber 180 .

In this way, the circulating air continuously circulates through the flow path in the multifunctional containment system, which will be described in more detail with reference to FIG. 6 .

2. Description of the flow path of the multifunctional storage system

The flow path of the multifunctional storage system according to the present invention will be described with reference to FIG. 6 . In FIG. 6 , the main components are divided and connected with arrows for explanation, where the arrows are shown to describe the flow of air rather than a separate flow path, and each component may be directly connected to each other.

When the fan 420 operates, outside air is introduced or circulating air starts to flow.

A negative pressure is formed inside the storage chamber 180 by the operation of the fan 420 , and outside air passing through the filter 151 is introduced through the partially or fully opened filter door 152 . When the filter door 152 is closed, outside air is not naturally introduced and only the circulating air in the flow path continues to circulate, or, in an embodiment of the present invention, outside air may be introduced through the lower filter 161 .

Due to the pressure difference formed by the operation of the fan 420 , the outside air introduced into the storage chamber 180 flows into the humidifying unit 200 as circulating air. The humidifier 200 humidifies the circulating air.

Here, it is important that the humidifier 200 is designed to be included as a part of the flow path of the circulating air rather than branching from the entire flow path of the circulating air. If the humidifier is located branched from the flow path of the circulating air, the pressure in the flow path of the circulating air by the operation of the fan 420 is higher than the pressure in the humidifier 200, so the humidified air generated by the humidifier is the circulating air. Instead of flowing into the flow path, the circulating air flows back into the humidifier 200 . In the present invention, in order to prevent this, the humidifying unit 200 is included as a part of the flow path of the circulating air, and in particular, as will be described later, the lower end of the humidifying unit exhaust flow path 230 of the humidifying unit 200 is submerged below the water surface in the water tank 210 . placed in a manner

Meanwhile, the circulating air humidified by the humidifier 200 is discharged from the humidifier 200 and introduced into the flow path inlet 300 . Similarly, it is due to the pressure difference formed by the operation of the fan 420 .

The circulation air introduced into the flow path inlet 300 flows into the circulation flow path 400 , and then passes through the fan 420 to reach the guide flow path 410 . When a plurality of fans 420 are provided, the air that has passed through each fan flows through independent flow paths separated by the guide flow barrier ribs 440 , and in the guide flow path 410 without the guide flow barrier rib 440 . are joined Here, the heating unit 450 is positioned to heat the circulating air.

The heated circulating air is introduced into the variable flow path module 500 . All or part of the circulating air may be exhausted according to the operation of the variable flow path module 500 , or all or part of the circulating air is introduced back into the storage chamber 180 through the flow path guide 600 and circulated.

The circulating air introduced into the storage room 180 is returned to the humidifying unit 200 together with the introduced outside air (a part or all of the filter door 152 is opened) or without the introduced outside air (the filter door 152 is closed). introduced, and in this way the circulating air continues to circulate until the fan 420 stops operating.

Meanwhile, in an embodiment of the present invention, outside air may be further introduced through the lower filter 161 . Outside air introduced through the lower filter 161 may be directly introduced into the flow passage inlet 300 through the lower flow passage 163 without being introduced into the storage chamber 180 and the humidifying unit 200 as circulating air. In another embodiment, the outdoor air introduced through the lower filter 161 may be introduced into the storage chamber 180 and then may be introduced into the flow path inlet 300 through the humidifying unit 200 .

3. Description of each component of the multifunctional storage system

3.1 Storage (180)

The storage room 180 will be described with reference to FIGS. 7 to 8 .

The storage room 180 is a space in which clothes are mounted, and a hanger 700 on which clothes are mounted on the upper inner surface, and a flow guide 600 for discharging air into the inside of the storage room 180 or the inside of the clothes hanger 700 . An upper opening 175 provided with is located.

A storage chamber filter 171 that filters out contaminants such as dust in the storage chamber 180 and a humidifier inlet 172 for introducing circulating air into the humidifier 200 are located on the lower inner surface of the storage chamber 180 . . The humidifier inlet 172 is airtightly connected to the humidifier inlet flow path 220 of the humidifier 200 .

The open portion through which air can flow inside the storage chamber 180 is the upper opening 175 and the humidifier inlet 172 , and the upper opening 175 is a portion for introducing circulation air into the storage chamber 180 . And the humidification unit inlet 172 is a portion for discharging the circulation air to the outside of the storage room (180).

Meanwhile, the horizontal cross-sectional area of the storage chamber 180 is gradually narrowed from the upper side to the lower side. This has the following three advantages.

First, as the area decreases as it goes downward, a pressure difference may occur, which may cause a natural downward flow of circulating air. That is, since circulating air flows downward like a kind of shower inside the storage room 180 (aka, 'air shower'), it is suitable to shake off contaminants such as clothes. This is because, in the case of upward flow, the dust or the like that has risen may be attached to the clothes again.

Second, the change of the cross-sectional area in the horizontal direction complicates the flow of air in the storage room 180 . A vortex is formed or a flow in a random direction is formed. As such, when the air flow in the storage room 180 becomes complicated, the clothes placed in the storage room 180 can be shaken in various directions, which is effective in removing contaminants, and circulating air (heated and humidified air) is evenly distributed throughout the clothes. The cleaning effect of clothes increases because it can be touched.

Third, considering the rectangular parallelepiped multifunctional storage system, a space in which the mechanical parts can be mounted is formed outside the lower part where the air of the storage room is narrowed. The multifunctional storage system according to the present invention is designed for miniaturization, and since the machine room provided at the bottom of the storage room is generally omitted, it is important to secure a space in which the machine parts (eg, the flow path inlet 300) are mounted, the storage room 180 ) can be secured by changing the area.

In the drawing, in consideration of the flat door 150, one side (front side) of the storage room 180 is vertical and the other side (inside) is curved.

In another embodiment, a shape in which the horizontal cross-sectional area of the storage chamber 180 gradually widens downward or becomes narrower and wider may be repeated. In this case, the above-described second and third advantages can be taken as they are. Although the first natural downward flow is difficult, it can be overcome by changing the RPM of the fan 420 or the like.

Looking at the rear surface of the storage room 180 , a lower portion of the rear surface forms one surface of the flow passage inlet 300 , and an upper portion of the rear surface forms one surface of the circulation passage 400 .

A guide passage guide 181 is positioned at a lower rear portion of the receiving portion 180 to form the flow passage inlet 300 . The guide flow guide part 181 protrudes backward from the rear surface of the receiving part 180 , and is in airtight contact with the separation plate 430 of the circulation flow path 400 to form the flow path inlet 300 .

In order to form the circulation passage 400 , the partition guide part 182 is positioned above the rear surface of the receiving part 180 forming one surface of the circulation passage 400 . The partition guide 182 serves to divide the circulation flow path 400 up to a desired height by airtightly contacting the partition wall 440 in the circulation flow path 400 .

On the other hand, in the present invention, there are two ways in which outside air is introduced, the first is direct inflow into the storage room 180 through the door 150 , and the second is inflow through the lower filter 161 . The first method is the main method, and the second method may be optionally included.

Inflow through the first door 150 will be described.

Looking at the front of the storage room 180, the door 150 is positioned on one surface in contact with the outside air, and the filter 151 is positioned here. Accordingly, the outside air introduced through the filter 151 is directly introduced into the storage chamber 180 .

The multifunctional storage system in the prior art is a method in which outside air flows into the machine room, not the storage room. In this case, the machine room must have a certain level of height in order to secure the area for the outside air to flow in and the filter area. Since the multifunctional storage system according to the present invention is for miniaturization, the outside air is directly introduced into the storage room 180 to exclude such a height of the machine room. Since outside air flows into the storage room 180 without going through the machine room, if there are many contaminants in the outside air, it can directly flow into the storage room 180, so that the performance of the filter 151 is secured and the filter door 152 is additionally installed. use it

Inflow through the second lower filter 161 will be described. Selective entry method.

11 , the lower filter 161 is positioned under the storage chamber 180 . That is, in the storage room 180 , the filter 151 is located on a portion other than the outer surface. The air introduced through the lower filter 161 passes through the lower flow path 163 divided by the lower separation plate 162 to reach the flow path inlet 300 . Accordingly, the outside air introduced through the lower filter 161 directly reaches the flow path inlet 300 and the circulation flow path 400 without passing through the storage chamber 180 .

Compared with the first method, there is a difference in that it flows into the flow path without passing through the storage room 180 , so that it can be utilized in various ways. For example, when a large amount of outside air is required to be introduced or when clean air discharge and air circulation for clothes management are required at the same time, it may be used together with the first method through the filter 151 (see FIG. 19B ). In addition, even when the filter door 152 is closed to prevent air from flowing through the storage room 180, a clean mode operation to be described later is possible (refer to FIG. 19D ).

3.2 Humidifier (200)

The humidifier 200 will be described with reference to FIGS. 9 to 11 .

The humidifying unit 200 includes a water tank 210 , a humidifying unit inlet flow path 220 , a humidifying unit exhaust flow path 230 , and an ultrasonic vibrator 240 .

The water tank 210 holds water up to a certain height. The height of the loaded water can be detected using a separate water level sensor (not shown), etc., so that the manufacturer can control it to rise to a desired height. Alternatively, the maximum water level may be guided to the user through printing in the water tank 210 . The user may put water in a cup and additionally supply water to the water tank 210 , or may remove the water tank 210 from the multi-function storage system and re-install the water tank 210 after filling it with water.

The humidification unit inlet flow path 220 is a flow path through which the circulating air inside the storage chamber 180 flows into the humidifying unit 200 . To this end, the upper end of the humidifying unit inlet flow path 220 is airtightly connected to the humidifying unit inlet 172 of the storage room 180 .

A circulating air inlet 221 is positioned at the lower side of the water tank 210 of the humidification unit inlet flow path 220 . Through this, the circulating air inside the storage chamber 180 is introduced into the water tank 210 .

An ultrasonic vibrator 240 is provided inside the water tank 210 . The ultrasonic vibrator 240 forms wet air using water in the water tank 210, so that the upper part of the water surface is filled with the wet air. In another embodiment of the present invention, the wet air may be provided in another way without the ultrasonic vibrator. For example, a humidifying filter or the like may be used.

The lower end of the humidification unit exhaust passage 230 is located inside the water tank 210, more specifically below the water level of the water tank 210, and the humidified air outlet 231 is located at the upper end, which is connected to the passage inlet 300. . Therefore, as the circulation air passes through the circulation air inlet 221 and flows into the water tank 210, the wet air formed inside the water tank 210 and filled is pushed and the flow path inlet 300 through the humidified air outlet 231. is discharged with

Here, since the lower end of the exhaust passage 230 of the humidifier is located below the water level in the water tank 210 , even if a high pressure flow is formed by the fan 420 , the phenomenon that the air is introduced into the water tank 210 is prevented do. In other words, the humid air generated by the humidifier 200 is supplied to the circulation passage 400 under any pressure condition, and the reverse flow of the circulating air on the circulation passage 400 to the humidifier 200 is prevented.

In one embodiment, for smoother humidified circulation air discharge, if the humidifier 200 is located on the left side when viewed from the front, the humidification unit exhaust flow path 230 may have a shape bent toward the right in a L shape ( 11).

In one embodiment, in order to more smoothly discharge the humidified circulating air, the humidification part exhaust flow path 230 may have a shape in which the cross-sectional area is gradually narrowed from the water tank 210 toward the humidified air outlet 231 .

3.3 Flow inlet (300)

The flow path inlet 300 will be described with reference to FIG. 12 .

The flow path inlet 300 is a space in which the circulating air humidified by the humidifying unit 200 flows into the circulation path 400 . As the circulation air discharged through the humidifier exhaust passage 230 spreads over a wide area in the passage inlet 300 , the circulation air is relatively evenly distributed to each of the plurality of fans 420 . If there is no flow path inlet 300 , most of the circulating air will flow into one fan 420 closest to the humidifier exhaust flow path 230 , and in this case, the load is biased only on one of the plurality of fans 420 . This may adversely affect the life of the equipment.

The flow path inlet 300 utilizes the space between the circulation flow path 400 and the storage room 180 . In other words, the flow path inlet 300 is located at the rear of the storage room 180 and at the front of the circulation flow path 400 .

Among the plurality of fans 420 of the flow path inlet 300 , a horizontal cross-sectional area of a fan located at a lower side of the storage chamber 180 may be narrower than a horizontal cross-sectional area of a fan located at an upper side.

The flow path inlet 300 may have an upwardly tapered shape, and in this case, the storage chamber 180 may be formed to correspond to the flow path inlet 300 .

As the flow path inlet 300 is formed as described above, compared to when there is no difference in the cross-sectional area of the upper and lower sides, the moving distance of air is reduced, so that air can flow faster to the plurality of fans 420 located at the upper side. Therefore, the air may be more evenly distributed to each of the plurality of fans 420 .

As described above, the storage room 180 has a shape in which the cross-sectional area in the horizontal direction becomes narrower toward the lower side, and thus the space between the storage chamber 180 is utilized (refer to FIG. 5 ). In other words, the flow path inlet 300 is located in a space located between the outermost edge and the innermost edge of the storage chamber 180 . Accordingly, there is no need to secure a separate additional space for forming the flow path inlet 300 , which is an important advantage for forming a compact multifunctional storage system.

One surface in the front direction of the flow passage 300 is the rear surface of the storage chamber 180 , and one surface in the rear direction of the flow passage 300 is the outer surface in the front direction of the circulation passage 400 .

Looking at the sidewall of the flow path inlet 300 , a part of the side surface is a guide flow guide part 181 provided on the rear surface of the storage room 180 , and the other part is a part protruding from the circulation flow path 400 .

An opening is formed in the portion corresponding to the fan 420 on the outer surface of the circulation passage 400 , and the circulation air introduced into the passage inlet 300 flows into the circulation passage 400 through this. When a plurality of fans 420 are included, since a plurality of openings are provided for each of the plurality of fans 420 , circulating air can be uniformly introduced through the plurality of openings, so that the circulating air can be evenly introduced into the plurality of fans 420 . do.

3.4 Circulation flow path (400)

The circulation flow path 400 will be described with reference again to FIGS. 7 to 8 .

A fan 420 is provided in the circulation passage 400 . The fan 420 provides power to continuously circulate the circulating air by rotation.

A plurality of fans 420 are provided, and two fans 420 are shown in the drawing. In general, the power of a fan is proportional to the diameter and thickness of the fan, and in order to provide the necessary power in a small multifunctional storage system, it is preferable to include a plurality of fans smaller in size than one fan having a larger size. When three or more fans are provided, the circulation flow path 400 may become excessively complicated, and in the present invention, two fans 420 are adopted as the optimal number. However, if included in the spirit of the present invention, the scope of the present invention will not be limited to the number of fans 420 .

In this case, the plurality of fans 420 may be positioned at different heights.

In this case, the plurality of fans 420 may be alternately disposed. That is, the plurality of fans 420 may have different heights and may be alternately disposed so as not to be simply stacked.

The circulation flow path 400 may be described by dividing it into an assembly part provided with a fan 420 and a guide flow path 410 part. The guide flow path 410 is again divided into a portion separated by the partition wall 440 and a portion not separated by the partition wall 440 .

A front side surface of each of the plurality of fan 420 assembly parts communicates with the flow path inlet 300 . Accordingly, the circulation air introduced into the flow passage inlet 300 flows backward toward the fan 420 and enters the circulation passage 400 of each of the plurality of fan 420 assembly parts. In the example shown in FIG. 8 , the two fans 420 each entered the assembly part. In addition, as described above, the circulation air is evenly distributed and introduced into the plurality of fan 420 assembly parts due to the flow path inlet 300 .

The circulating air entering each of the plurality of fan 420 assembly parts moves along the guide flow path 410 by the power of the fan 420 .

The guide passage 410 is divided by a partition wall 440 by a predetermined length. Air entering each of the plurality of fan 420 assembly parts is divided by the length of the partition wall 440 and flows.

The length of the guide passage 410 divided by the partition wall 440 may be variously adjusted. When the partition wall 440 is short, air introduced from each of the plurality of assembly parts of the fan 420 is quickly joined, and when the partition wall 440 is long, conversely, the confluence of the introduced air is slowed. When the confluence of the introduced air is fast, the air flows rapidly and statically, so that even heating by the heating unit 450 is possible. If the confluence of the introduced air is delayed, the heating may be relatively uneven for dynamic flow. However, the flow of the air flowing into the storage room 180 becomes more complicated and a random flow can be formed, which is effective for removing dust from clothes. to be. Accordingly, the manufacturer may appropriately adjust the length of the partition wall 440 according to the specifications of the product and the shape and length of the actual circulation passage 400 .

At this time, the length of the partition wall 440 on the circulation passage 400 may be determined according to the outputs and positions of the plurality of fans 420 , but is not limited thereto.

In this case, the output of the plurality of fans 420 may mean the size and number of rotations of the plurality of fans 420 , and the power of the fans, but is not limited thereto.

The heating unit 450 is located at the distal end of the guide passage 410 . The heating unit 450 heats the circulating air. Accordingly, heated and humidified circulating air flows into the storage chamber 180 . The heated and humidified circulating air performs a function of removing odors and contaminants from clothes mounted in the storage room 180 .

In the drawing, the heating unit 450 is located in the guide flow path 410 without the partition wall 440 , but may be located in a portion where the partition wall 440 is present. In addition, the heating unit 450 is located in the circulation passage 400 , but may be located in a variable passage module 500 to be described later beyond the circulation passage 400 , and in the variable passage module 500 , the exhaust passage 520 . It may be located after branching. In this case, there is an advantage that all of the air heated by the heating unit 450 can flow to the receiving unit 180 without being discharged to the outside.

3.5 Variable Euro Module (500)

The variable flow path module 500 will be described with reference to FIGS. 13 to 16 .

The variable flow path module 500 discharges some or all of the circulation air flowing through the circulation flow path 400 to the outside, or introduces some or all of the circulation air into the storage chamber 180 . In other words, one end of the variable flow passage module 500 is connected to the circulation passage 400 and circulated air is introduced therefrom, and the other end is connected to the storage chamber 180 through the passage guide 600 and circulated air therethrough. emits

The variable flow path module 500 includes a variable flow path 510 connecting the circulation flow path 400 and the storage room 180 , and an exhaust flow path 520 branching from the variable flow path 510 and communicating with the outside and selectively opening and closing. and a variable guide 530 for changing the flow direction of the circulating air, and a power member 540 for providing power to the variable guide 530 .

The variable guide 530 controls opening and closing of the branched exhaust flow path 520 . The variable guide 530 may close the exhaust flow path 520 so that all the circulating air flows into the storage chamber 180 ( FIG. 16A ), or open the exhaust flow path 520 to exhaust some of the circulating air to the outside. can be done (Fig. 16b). At this time, if the flow guide 600, which will be described later, is closed so that the circulation air does not flow into the storage chamber 180, all of the circulation air is exhausted. The exhaust flow path 520 is opened and closed according to the control of the variable guide 530, which implements various operating modes of the multifunctional storage system according to the present invention, which will be described later with reference to FIG. 19 .

In the present invention, since the circulation flow path 400 is installed at the rear portion of the storage room 180 for miniaturization, the variable flow path 510 is formed in an inverted U shape to connect the circulation flow path 400 and the storage room 180 . is formed However, the variable flow path 510 may have any shape connecting the circulation flow path 400 to the storage chamber 180 .

The exhaust flow path 520 is branched from the variable flow path 510 . As described above, when the variable flow path 510 has an inverted U-shape, the exhaust flow path 520 may be positioned at one end of a corner where the curve is formed.

The shape of the variable flow path 510 and the exhaust flow path 520 is better shown in FIG. 16A .

A variable guide 530 for determining a flow direction of air is provided at a portion where the exhaust passage 520 is branched.

As shown in FIG. 15 , the variable guide 530 rotates and includes a first guide 531 , a second guide 532 , and a third guide 533 about a rotation shaft 535 . The rotation shaft 535 is directly or indirectly connected to the power member 540 to rotate.

When the rotation shaft of the variable guide 530 is located inside the variable flow path 510 , a large amount of load due to the air flowing during the rotation of the variable guide 530 is applied, so that greater power is required and equipment durability is not good. Conversely, when the rotation shaft of the variable guide 530 is positioned outside the variable flow path 510 , it is difficult to manufacture a continuous shape in which the inner surface of the variable flow path 510 is smoothly connected so as not to obstruct the flow of circulating air. A separate member is required.

Therefore, according to the present invention, the rotation shaft 535 of the variable guide 530 is positioned on the boundary surface of the variable flow path 510 rather than the inside or outside of the variable flow path 510 , specifically, the variable flow path upper surface 511 . It was positioned on the extension line, and more specifically, it was positioned on the interface where the exhaust channel 520 is branched from the variable channel 510 . Through this, when the variable flow path 510 closes the exhaust flow path 520 ( FIG. 16A ), the flow of circulating air is not disturbed, and a large amount of power is not required to operate the variable guide 530 .

When the variable flow path 510 closes the exhaust flow path 520 ( FIG. 16A ), the variable guide 530 closes the exhaust flow path 520 in order not to obstruct the flow of the circulating air, that is, the first guide ( 531 and the inner surface of the second guide 532 are preferably continuous with the inner surface of the variable passage upper surface 511 along an extension line.

In addition, as well shown in FIG. 16A , the first guide 531 has an inner cross-section longer than its outer cross-section, so that it is preferably shaped to protrude from the inside, and the upper surface of the variable flow path in contact with the first guide 531 . The portion (511) is preferably shaped to protrude from the outside by forming an outer cross-section longer than the inner cross-section to correspond thereto. This prevents the circulating air from being exhausted by the undesirable rotation of the variable guide 530 by the circulating air when the circulating air flows. As shown in FIG. 16A , when the variable guide 530 closes the exhaust flow path 520 , even if some of the circulating air flowing in the counterclockwise direction flows toward the variable guide 530 and passes through the first guide 531 , ) due to the shape of the variable guide 530 is not opened, rather the degree of airtightness is strengthened.

For the same reason, the second guide 532 has a shape that protrudes from the outside by having an outer cross section longer than the inner cross section, and the variable passage upper surface 511 in contact with the second guide 532 has an inner cross section corresponding thereto. It is preferable that the shape is formed longer than the outer cross-section and protrudes from the inside.

When the variable guide 530 rotates to open the exhaust passage 520 ( FIG. 16B ), the third guide 533 comes in contact with the variable passage upper surface 511 and guides the exhausted circulating air only in a certain direction. do.

In order for the third guide 533 to come into contact with the variable flow path upper surface 511 more efficiently, one of the first guide 531 or the second guide 532 has one fixed end of the third guide not the rotation shaft 535 . It is preferable to be located in either one. In other words, the rotation axis of the third guide 533 is different from the rotation axis 535 of the variable guide 530 and is eccentric to a certain extent. Through this, the length of the third guide 533 can be formed to be longer than the length from the rotation shaft 535 to the upper surface 511 of the variable flow path, so that the third guide 533 is press-fitted and circulated air more effectively in one direction You can guide it to be exhausted only.

Meanwhile, in the illustrated embodiment, the heating unit 450 is located on the circulation flow path 400 , but in another embodiment of the present invention not shown, the heating unit 450 is located on the variable flow path module 500 . may be In particular, when the heating unit 450 is installed on the variable flow path module 500 and the exhaust flow path 520 is installed at the rear end of the branched portion, some of the air heated by the heating unit 450 is not exhausted. It may be more effective to dehumidify the circulating air or the storage chamber 180 by allowing all of them to flow into the storage chamber 180 .

3.6 Euro Guide (600)

The flow guide 600 will be described with reference to FIGS. 17 to 18 .

The flow guide 600 is installed in the upper opening 175 of the storage chamber 180 , and connects the variable flow path 500 and the storage chamber 180 .

The flow guide 600 is an air shot outlet 610 for realizing a so-called air shot for discharging circulating air to the inside of the clothes hanger 700 and spraying air to the inner surface of the clothes mounted on the clothes hanger 700 , the outside of the clothes hanger 700 . The storage room outlet 620 that directly discharges circulating air into the storage room 180 to spray air on the outer surface of the clothes mounted therein and the circulating air are better guided toward the air shot outlet 610 and the storage room outlet 620 and a guide member 650 to enable it.

The lower surface of the flow guide 600 corresponds to the upper opening 175 of the storage chamber 180 and is airtightly connected.

The air shot outlet 610 and the storage chamber outlet 620 are positioned on the lower surface of the flow guide 600 . A coupling portion to which the clothes hanger 700 can be connected may be located at the lower end of the air shot outlet 610 . A plurality of storage chamber discharge ports 620 may be provided. In order to evenly discharge the circulating air to the left and right of the clothes mounted on the hanger 700, the storage room outlet 620 is preferably symmetrical with respect to the air shot outlet 610, one each on the left and right in the drawing. but is not limited thereto.

Each of the air shot outlet 610 and the storage chamber outlet 620 may have an openable and openable grill positioned, so that one or more outlets or all outlets may be selectively opened or closed as needed. It is also possible to implement various operating modes using this, which will be described later with reference to FIG. 19 .

Since the guide member 650 has to guide the circulating air flowing through the entire upper surface of the flow guide 600 to the respective outlets 610 and 620, it is preferable to be positioned at the boundary between the respective outlets 610 and 620. A triangular prism shape laid down to distribute air is preferred.

3.7 Hanger(700)

The hanger 700 will be described with reference again to FIGS. 17 to 18 .

The hanger 700 includes a coupling part 710 coupled to the flow guide 600 , an elastic part 720 made of an elastic material located at the lower end of the coupling part 710 , and a mounting part 730 on which clothes are mounted. do.

By the coupling portion 710, the hanger 700 is detachable by the user. Therefore, the user can use the method in which the clothes are comfortably mounted after removing the hanger 700 and then mounted in the storage room 180 . In addition, the user may selectively use any one of the various hangers (700). In addition to the general hanger shown in FIG. 18, it is possible to use without limitation, such as a trouser or skirt hanger, a two-piece hanger, and the like.

The elastic part 720 allows the clothes hanger 700 to be shaken by the circulating air supplied to the inside of the storage chamber 180 through the flow guide 600 . Through this, it is possible to achieve the effect of brushing off contaminants from the clothes. In particular, as described above, the present invention has various structural features for forming a random flow of circulating air (the horizontal cross-sectional area of the storage room 180 is gradually narrowed from the upper side to the lower side, and the partition wall 440 is formed. The circulation flow path 400 to slow the mixing of the two fans 420 used, etc.), may be used with these features to be more effective in removing contaminants.

4. Description of the operating mode of the multifunctional storage system

An operating mode of the multifunctional storage system according to the present invention will be described with reference to FIGS. 19A to 19D. It should be noted that the operating mode described herein is merely an example, and any other operating mode may be implemented within the spirit of the present invention described in the claims.

Figure 19a shows the air flow in 'circulation mode'. The humidified high-temperature circulating air flows into the storage chamber 180 . Using this, it is effective to remove contaminants such as dust and odor substances from the clothes mounted in the storage room 180 .

19B shows the air flow in 'exhaust and clean mode'. While removing contaminants such as dust and odor substances from the clothes mounted in the storage room 180, some of the circulating air is exhausted to the outside. The circulating air exhausted to the outside is clean air filtered through the filter 151 . In one embodiment, the air that has passed through the lower filter 161 may be further used.

19C shows the air flow in 'clean mode'. The humidified high-temperature circulating air does not flow into the storage chamber 180 . All of the clean air filtered through the filter 151 does not pass through the storage room 180 (passes only when it is introduced) but is exhausted, thereby performing the same function as the air purifier. By controlling the operations of the humidifying unit 200 and the heating unit 450 in various ways, it may be operated in a humidifying clean mode, a dehumidifying clean mode, as well as a general clean mode.

19D shows the air flow in another embodiment of the clean mode. The air that has passed through the lower filter 161 is used and the air is not introduced into the storage chamber 180 . This is suitable for protecting clothes stored inside the storage room when the air quality outside the multifunctional storage system is poor (eg, when the kitchen smells like cooking).

These operating modes may be variously combined or applied in various ways.

For example, the circulation mode is operated for a predetermined time, the exhaust and clean mode are operated for a predetermined time thereafter, and then, when the multifunctional storage system is idle, the cleaning mode may be automatically operated.

When performing the exhaust and clean mode operation, outside air may be introduced only through the filter 151, but if it is necessary to introduce a large amount of outside air and discharge a large amount of clean air due to poor quality of outside air, the lower filter ( 161) can also allow outside air to flow in.

For another example, if it is detected that the outdoor air quality is not good during the clean mode operation, the filter door 152 is closed to prevent the outside air from flowing into the storage room 180 to protect the mounted clothes while removing the lower filter 161 . It can be carried out in a way that outside air is introduced through the

In the above, the present specification has been described with reference to the embodiments shown in the drawings so that those skilled in the art can easily understand and reproduce the present invention, but these are only exemplary, and those skilled in the art can make various modifications and equivalent other It will be appreciated that embodiments are possible.
