Description

Air management device

Technical Field

The present invention relates to an air management device, and more particularly, to an air management device installed on a floor of a living space to manage air in the living space.

Background

The air management device of the present invention is a device that maintains the air within a given space in a desired condition to provide a comfortable environment for the occupants of the space. Air conditioners are a typical example of air management devices.

There are various types of air conditioners, for example, an integral type air conditioner in which an indoor unit and an outdoor unit constituting the air conditioner are integrally installed at a window or the like, and a separate type air conditioner in which the indoor unit is installed in an indoor space and the outdoor unit is installed outdoors, and the indoor unit and the outdoor unit are separated from each other. The separate type air conditioners include a ceiling type air conditioner installed on a ceiling of an appropriate indoor space, a floor type air conditioner installed in a vertical state in the indoor space, and a wall type air conditioner installed on an upper end of a wall surface of the indoor space.

Recently, since living spaces such as a living room, a bedroom, a room, a kitchen, a study, etc. are communicated, demand for products capable of maximizing efficiency and functions of the living spaces is gradually increasing. As the trend of integrating living spaces and the trend of emerging core homes overlap each other, demands for various home electronic products are gradually increasing. Air management devices are typical home electronics products that can maintain temperature, humidity, cleanliness, etc. within a living space, and it is necessary to provide products for the communication of living spaces and trends toward core homes.

It is important for an air conditioner used in a living space to consider compatibility with furniture and the like in the living space. However, the conventional air conditioner has a problem that it is not compatible with other furniture in the living space.

Patent document 1 discloses a wall-mounted air conditioner, and the wall-mounted air conditioner disclosed therein has a problem that it is difficult to coordinate with surrounding furniture or the like because it is provided to protrude from the upper end of the wall surface.

Patent document 2 discloses a floor type air conditioner in which three discharge ports are provided in the height direction, and a fan is provided at each discharge port to discharge air into an indoor space. Since the floor standing air conditioner is protruded upward from the floor surface, it is necessary to make a neighboring peripheral space empty for the intake and discharge of air, and thus it is difficult to make a coordination with the periphery.

Patent document 3 also discloses a vertical air conditioner. Although the vertical air conditioner attempts to form a good balance with the surrounding area by designing various external shapes, it has a problem that it is difficult to form a good balance with other furniture because it is projected upward from the floor in a tower shape.

In order to solve the problems of the above patent documents, air management devices that can be installed on the floor of a living space and have a housing extending long in the right and left direction have been studied.

Further, since the floor of the living space is a place which can be easily accessed by the occupant, it is necessary to prevent the member for connecting the air management device and the outside from being easily exposed to the outside.

Further, in the above patent document, since air is delivered only to one space where the air conditioner is installed to maintain air in an ideal state, there is a problem that the demand for diversification and unification of living spaces cannot be satisfied.

Further, in the conventional patent documents, the air conditioner can perform only the function of the air conditioner itself, and there is a problem that the installation space cannot be effectively utilized.

The external appearance of the housing 10 has a furniture shape. For example, wood or a material having a wood appearance may be used as the material constituting the appearance of the housing 10. That is, at least the outer appearances of the side plates 12, the top plate 14, the front plate 15, the first moving plate 16, and the second moving plate 16' among the constituent elements constituting the outer appearance of the housing 10 are made of wood or a material having a wood appearance.

When the housing 10 is viewed from the front or above, the interior of the housing 10 is divided into three spaces by the first partition wall 19 and the second partition wall 19'. As can be seen from fig. 2 and 3, an air flow space 20 and a first space 22 are divided by a first partition wall 19, and an air flow space 20 and a second space 24 are divided by a second partition wall 19'.

An air flowing space 20 is formed inside the case 10. The air flow space 20 is a place where air in the living space sucked through the suction port 11 'flows while performing heat exchange, and the air in an ideal state after the heat exchange is discharged to the living space through the discharge ports 15' -1, 15 '-2, 15' -3.

A first space 22 partitioned from the air flow space 20 is formed by the first partition wall 19. The first space 22 is a portion where one additional discharge unit 200 of the humidifying device 400 and the additional discharge unit 200 described below is provided. The first space 22 is opened and closed by the first moving plate 16 at a portion where the humidifying device 400 is provided.

A second space 24 partitioned from the air flow space 20 is formed by a second partition wall 19'. The second space 24 is a portion where one additional discharge unit 200 of the additional discharge units 200 described below is disposed and where a machine room 500 in which a control unit and the like are installed is disposed. The portion where the machine chamber 500 is disposed is opened and closed by the second moving plate 16'.

The left-right length of the air flow space 20 is 2 times or more the left-right length of the first space 22 and the second space 24. The left and right length of the air flow space 20 may be set to ensure the number of the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 formed in the front plate 15 of the housing 10.

As shown in fig. 4, a heat exchanging device 100 is provided in the air flowing space 20, and includes a structure for exchanging heat with the air sucked through the suction port 11 ', a structure for discharging the air through the discharge ports 15' -1, 15 '-2, 15' -3, and the like. A filter unit 300 is provided at a position after passing through the suction port 11'.

The air passing through the filter unit 300 flows through the air flow path 102 formed in the air flow space 20. The air flow path 102 is provided with a heat exchanger 104. The heat exchanger 104 is a device that exchanges heat between the air flowing through the air flow path 102 and the working fluid of the heat exchange cycle. For example, during a cooling operation, heat from the air is received by the working fluid in the heat exchanger 104, transferred to the outdoor unit, and then discharged to the outside. In heating operation, air receives heat from the working fluid and transfers the heat to the living space while passing through the heat exchanger 104. Of course, during heating operation, the heat exchanger 104 may not be used and heat may be received from other devices. The working fluid transferred from the outdoor unit is transferred to the heat exchanger 104 through the inlet pipe, and the working fluid passed through the heat exchanger 104 is transferred to the outdoor unit through the outlet pipe.

The lower portion of the heat exchanger 104 has a drain pan 108. The drain pan 108 collects and drains condensed water condensed from the air passing through the heat exchanger 104.

In order to form the air flow path 102, the air flowing space 20 has a structure to guide the flow of air. First, there is an inlet guide 110 opposite to the filter unit 300. The inlet guide 110 is located at a region corresponding to the suction port 11'. The inlet guide 110 is opposite to most of the area of the suction port 11'. The inlet guide 110 is formed with a guide inclined surface 110 'such that air passing through a region of the suction port 11' near the front end of the housing 10 smoothly flows toward the rear plate 13. The guide inclined surface 110 'is farther from the suction port 11' as it approaches the back plate 13.

The front end of the inlet guide 110 extends toward the back plate 13, and the front end of the inlet guide 110 is positioned at a position around 2/3 of the suction port 11' with respect to the front-rear direction of the housing 10. The purpose of setting the front end of the inlet guide 110 in this way is to maximize the transfer of air to the rear of the air flow path 102 inside the housing 10. The top surface of the inlet guide 110 may be provided with the drain pan 108 and a wind guide 120 described below.

The air flow path 102 has an upper guide 112. The upper guide 112 forms a ceiling of the air flow path 102. The upper guide 112 extends from the back plate 13 to a wind guide portion 120 described below. The portion where the upper guide 112 meets the back plate is formed as a curved surface so as not to generate eddy current. It is preferable to avoid the back plate 13 from being orthogonal to the upper guide 112.

Although not shown, a portion of the inner surface of the back plate 13 corresponding to the air flow path 102 may be formed in a curved surface. That is, the back plate 13 and the upper guide 112 may be formed as a continuous curved surface. For this, the rear surface of the back plate 13 may be formed to protrude to the outside.

The inlet guide 110 and the upper guide 112 are preferably made of a material having good heat insulation properties. If the inlet guide 110 and the upper guide 112 are not materials having good insulation properties by themselves, it is necessary to form a material having good insulation properties on the surface to prevent heat exchange with the periphery. The upper guide 112 is closely attached to the upper end of the heat exchanger 104 and extends to the air guide part 120.

An air guide portion 120 is provided in front of the heat exchanger 104. Fig. 6 shows the air guide portion 120. The air guide part 120 is provided therein with driving fans 130, 130 ', and 130 ″ for supplying motive power to suck air into the air flow path 102 and discharge the air into the indoor space through the discharge ports 15' -1, 15 '-2, and 15' -3. The air guide portion 120 branches the air passing through the heat exchanger 104. In this embodiment, the air flows in three paths.

The air guide part 120 is made of a material having good heat insulation properties. This is for the air heat-exchanged while passing through the heat exchanger 104 to maintain its state and be transferred to the indoor space.

The frame of the air guide part 120 is formed by a main air guide part body 122 made of a material having good heat insulation properties. The air guide portion main body 122 has a predetermined thickness in the front-rear direction, and a plurality of fan spaces 124, 124', 124 ″ are formed therein. As shown in fig. 7, driving fans 130, 130 ', 130 ″ described below are provided in the fan spaces 124, 124', 124 ″ respectively. The fan spaces 124, 124 ', 124 "are formed in a cylindrical shape so that the driving fans 130, 130', 130" can be rotated therein. The fan spaces 124, 124', 124 "are open on the side opposite the heat exchanger 104 to form an inflow port 126. However, only a portion of the fan spaces 124, 124 ', 124 ″ corresponding to the discharge ports 15' -1, 15 '-2, 15' -3 is opened. That is, an outflow port 128 is formed at a position relatively close to the upper portion in the fan spaces 124, 124', 124 ″. The outflow port 128 is formed in the front plate 15 at a position corresponding to the first to third discharge ports 15 ' -1, 15 ' -2, 15 ' -3. The flow outlet 128 has a cross-sectional flow area which is smaller than the cross-sectional flow area of the fan spaces 124, 124', 124 ". The outflow port 128 is formed at a position relatively close to the upper end of the fan space.

Further, a branch flow passage 129 is formed on the inner surface side of each of the first fan space 124 and the third fan space 124 ″. The branch flow path 129 is a portion through which the air in the first fan space 124 and the third fan space 124 ″ can flow and which transmits the air to the additional discharge unit 200 described below. The branch flow channel 129 is open to both side surfaces of the air guide part 120, and is connected to the first space 22 and the second space 24.

As shown in fig. 7, the fan spaces 124, 124 ', 124 "are provided with driving fans 130, 130', 130", respectively. The drive fans 130, 130', 130 "are rotated by respective corresponding fan motors 132 to provide the motive force for the air flow. The fan motor 132 is driven by a control unit 600 described later. Therefore, in the present embodiment, the control unit 600 operates the driving fans 130, 130 ', 130 ″ or controls the driving fans 130, 130 ', 130 ″ means that the control unit 600 operates (rotates) the driving fans 130, 130 ', 130 ″ by driving the fan motor 132. In this embodiment, a total of three driven fans 130, 130', 130 "are used. Of course, the number of the driving fans 130, 130', 130 ″ may be at least two or more. For example, four driving fans or five driving fans may be used, wherein the driving fans 130 and 130 ″ at both ends may be provided to transmit air to the additional discharge unit 200 described below, and all the driving fans 130, 130', and 130 ″ may be provided to transmit air to the front of the casing 10. These driving fans 130, 130 ', 130 "are referred to as a first driving fan 130, a second driving fan 130', and a third driving fan 130", respectively. The driving fans 130, 130', and 130 ″ use turbo fans that suck air from the rotation axis direction and discharge the air in the centrifugal direction.

In the present embodiment, the blades 141, 142, and 143 are provided at positions corresponding to the three driving fans 130, 130 ', and 130 ″, respectively, that is, the first to third discharge ports 15' -1, 15 '-2, and 15' -3, respectively. The first discharge port 15 ' -1 is provided with a first vane 141, the second discharge port 15 ' -2 is provided with a second vane 142, and the third discharge port 15 ' -3 is provided with a third vane 143. These vanes 141, 142, and 143 are driven by a separate driving source to open and close the discharge ports 15 ' -1, 15 ' -2, and 15 ' -3, respectively, thereby setting the discharge direction of the air.

The opening of the vanes 141, 142, 143 is achieved by the driving of the driving motors 141 ', 142 ', 143 '. The output shafts of the driving motors 141 ', 142 ', 143 ' are connected to the rotation center shafts of the blades 141, 142, 143, and the rotation center shafts rotate to rotate the blades 141, 142, 143. The driving motors 141 ', 142 ', 143 ' are driven by the control part 600. Therefore, the control unit 600 opens or closes or operates the blades 141, 142, and 143 or controls the blades 141, 142, and 143 means that the control unit 600 operates the blades 141, 142, and 143 by driving the driving motors 141 ', 142 ', and 143 '. The driving motors 141 ', 142 ', 143 ' may open the blades 141, 142, 143 while adjusting the opening angle.

The back surfaces of the blades 141, 142, 143 have a rotation center piece 145 combined with the driving motors 141 ', 142 ', 143 '. A center hole 145' is formed at the rotation center piece 145. Two rotation center pieces 145 are formed at one vane 141, 142, 143, and an output shaft of the driving motor 141 ', 142', 143 'is coupled to a center hole 145' of one of them.

The driving motors 141 ', 142 ', and 143 ' are fixed in the installation grooves 150 formed in the air guide part 120. In order to install the driving motors 141 ', 142 ', and 143 ' in the installation grooves 150 of the air guide part 120, a motor base 146 is required. Thus, one side surface of the motor seat 146 has a shape capable of receiving a part of the driving motors 141 ', 142', and 143 ', and is fixedly installed in the installation groove 150 in a state of being coupled with the driving motors 141', 142 ', and 143'.

One vane 141, 142, 143 has two rotation center pieces 145, one of which is combined with the driving motors 141 ', 142 ', 143 ' and the other of which is provided with a rotation center shaft 147. The rotation center axis 147 serves as a rotation center of the blades 141, 142, and 143. The support pieces 149 are provided at both ends of the rotation center shaft 147, and the support pieces 149 are fixedly installed in the other installation groove of the air guide part 120. One rotation center shaft 147 may simultaneously penetrate the two rotation center pieces 145.

The blades 141, 142, and 143 may be provided on the discharge ports 15 ' -1, 15 ' -2, and 15 ' -3, and may be provided on the rear surface of the front plate 15 in addition to the air guide part 120 as in the illustrated embodiment. The direction of the air discharged through the discharge ports 15 '-1, 15' -2, 15 '-3 may be different according to the operation of the blades 141, 142, 143, and the air may be directly discharged to the front of the discharge ports 15' -1, 15 '-2, 15' -3, for example. At this time, the heat-exchanged air is directly delivered to the user. Further, the air may be discharged from the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 to the upper front portion, and at this time, the air having exchanged heat may be indirectly managed without being directly transferred to the user. The direction of discharging the heat-exchanged air through the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 may be controlled by a preset operation mode.

The output shafts of the driving motors 141 ', 142 ', 143 ' are operated by setting a speed and a torque by a speed reduction unit therein. The rotation angles of the vanes 141, 142, 143 are set according to the degree of operation of the output shafts of the drive motors 141 ', 142 ', 143 '. Here, the rotation angles of the blades 141, 142, and 143 may be set by a user by selecting a corresponding operation mode from preset operation modes.

The driving fans 130, 130', 130 ″ may be driven simultaneously, or may be selectively driven in combination. That is, the fans 130, 130', 130 ″ may be driven in various combinations depending on the operating mode of the air management device.

First, all the driving fans 130, 130', 130 ″ are operated, all the blades 141, 142, 143 are opened, and the heat-exchanged air is discharged to the front of the case 10. At this time, the branch flow passage 129 of the air guide portion 120 is closed by the damper 206, and air is prevented from being supplied from the branch flow passage 129 to other portions.

The damper 206 is operated by a damper drive motor (not shown). The damper driving motor is driven by the control part 600. Therefore, the control unit 600 opens and closes the damper 206 or controls the damper 206 means that the control unit 600 drives the damper driving motor to operate the damper 201.

Then, only one of the three driving fans 130, 130', 130 ″ is driven to open the corresponding blades 141, 142, 143, and the heat-exchanged air is discharged forward. At this time, the branch flow passage 129 of the air guide portion 120 is also closed by the damper 206, and air is prevented from being supplied to the branch flow passage 129.

Then, in a state where all the vanes 141, 142, and 143 are closed, air is supplied to the additional discharge portion 200 described below. At this time, the first driving fan 130 and the third driving fan 130 ″ are driven, and the air is transferred to the additional discharge unit 200 through the branch flow path 129 and discharged to the indoor space. Of course, it is desirable to open the damper 206 to allow air to flow through the branch flow path 129.

In addition, in a state where air is supplied to the branch flow path 129 by the first driving fan 130 and the third driving fan 130 ″, the second driving fan 130' is also driven, and the second blade 142 is opened to discharge the heat-exchanged air to the front of the case 10.

As shown in fig. 1 and 2, the casing 10 has additional discharge portions 200 on both sides of the top surface thereof. The additional discharge unit 200 can protrude an ejection pipe 234, which will be described below, from the top surface of the casing 10, and can transfer heat-exchanged air to a wider area.

The structure of the additional discharge unit 200 will be described in detail with reference to fig. 10 to 16. An additional discharge portion 200 may be provided in at least one of the first space 22 and the second space 24 of the housing 10. In the figure, the additional discharge unit 200 is provided in both the first space 22 and the second space 24, and the additional discharge unit 200 provided in the first space 22 will be described as an example.

As shown in fig. 11, the first space 22 is provided with a first space frame 202. The first space frame 202 can be seen in fig. 2. The first space frame 202 divides the first space 22 into an additional discharge unit 200 and a humidifying device 400 described below. A frame space 203 is formed at one side of the first space frame 202, and the frame space 203 is opened and closed by the first moving plate 16. The first moving plate 16 moves left and right with respect to the housing 10 to open and close the frame space 203.

As shown in fig. 10 and 11, a connection pipe 204 is provided on the right side surface of the first space frame 202. One end of the connection pipe 204 communicates with the branch flow passage 129 of the air guide part 120. As shown in fig. 10, the connection pipe 204 is bent to

And (4) shape. The connection pipe 204 is not necessarily bent in the shape as shown in the drawing, and may be made in various shapes.

The other end of the connection pipe 204 communicates with a vertical pipe 208 described below. A connection flow path 205 through which air flows is formed inside the connection pipe 204. The flow of air to the connecting flow path 205 is controlled by a damper 206. The damper 206 is provided at the inlet of the connection flow path 205. The operation of the damper 206 controls the air supplied to the connection flow path 205.

The first space frame 202 has a vertical tube 208. The first space frame 202 itself is formed with the vertical tubes 208. The vertical pipe 208 is not necessarily formed at the first space frame 202. The vertical pipe 208 may be separately manufactured and then disposed in the first space 22. The vertical pipe 208 is extended in a vertical direction to guide the lifting of the lifting box 214 described below so that the eject pipe 234 is lifted along a predetermined track.

The vertical pipe 208 is provided with a lift case 214 and an eject pipe 234, and a vertical flow path 210 for lifting and flowing air. The vertical flow path 210 accommodates an ejector pipe 234 and an elevator case 214 in an elevatable manner. The vertical flow path 210 becomes a path through which air flows in a state where the eject pipe 234 and the lift case 214 have been lifted.

An elevating rack 212 is provided along the inner surface side of the vertical flow path 210 from the lower portion to the upper portion. The lifting rack portion 212 is engaged with a lifting drive gear 232 described below to move the lifting drive gear 232 up and down. The lifting rack portion 212 can be seen in fig. 15 and 16.

A lift case 214 is provided inside the vertical flow path 210. The shape of the lift cage 214 is best seen in fig. 13 and 14. The elevating box 214 ascends and descends along the vertical flow path 210. The shape of the cross section of the elevating box 214 is the same as the shape of the cross section of the vertical channel 210 except for a recess 221 described below. The outer side surfaces of the elevating case 214 move while contacting the inner surface of the vertical flow path 210.

As shown in fig. 14, a rotary support ring 216 is provided vertically through the lift case 214. The rotary support ring 216 has a cylindrical shape and has a communication passage 218 formed therein. The rotary support ring 216 supports and rotates a rotary support 238 of the eject tube 234 described below. The communication flow path 218 communicates the vertical flow path 210 with an ejection flow path 236 of an ejection tube 234 described below. A rotation support portion 238 at a lower end portion of the eject pipe 234 described below is rotatably inserted into the rotation support ring 216.

A fan installation part 219 is provided inside the communication flow path 218. In this embodiment, the fan-setting portion 219 is formed in a cross shape. The fan installation unit 219 is provided with an ejection driving fan 224 for pressurizing air discharged from the additional discharge unit 200. The eject drive fan 224 is driven by an eject drive motor (not shown). The eject drive motor is driven by the control portion 600. Therefore, the control section 600 operating the eject driving fan 224 or controlling the eject driving fan 224 means that the control section 600 drives the eject driving motor to operate (rotate) the eject driving fan 224.

A rotary motor receiving portion 220 is formed in the rotary support ring 216 of the lift case 214, and a rotary motor 226 described below is provided therein. A recess 221 is formed on one outer surface of the elevating case 214, and as shown in fig. 14, an elevating motor housing 222 is formed in the recess 221. The recess 221 is formed to maximize the area contact between the outer surface of the elevating housing 214 and the inner surface of the vertical flow path 210.

As shown in fig. 10, a pop-up driving fan 224 is provided in the fan installation part 219 of the elevator case 214. The ejection drive fan 224 pressurizes the air at the communication flow path 218 to blow the air farther. That is, the pop-up driving fan 224 functions to pressurize the air transferred to the branch flow path 129 by the first driving fan 130 or the third driving fan 130 ″ and passing through the connection pipe 204 and the vertical pipe 208.

A rotary motor 226 is provided in the rotary motor housing portion 220 of the lift case 214. An output shaft of the rotary motor 226 is provided with a rotary drive gear 228. The eject tube 234, described below, is rotated by driving the rotation motor 226.

The elevation motor housing 222 of the elevation housing 214 is provided with an elevation motor 230. An elevation drive gear 232 is provided on an output shaft of the elevation motor 230, and engages with the elevation rack portion 212. The lifting drive gear 232 is engaged with the lifting rack portion 212 and is lifted up and down along the lifting rack portion 212. Accordingly, the lifting box 214 can be lifted. The eject pipe 234 is lifted and lowered by the lifting and lowering of the lift box 214. The lifting motor 230 is driven by the control unit 600. Therefore, the control unit 600 moves the eject tube 234 up and down or controls the move of the eject tube 234 up and down means that the control unit 600 drives the lift motor 230 to move the eject tube 234 up and down.

The ejection tube 234 passes through the top plate 14 of the housing 10, rises upward, and then descends. The ejector tube 234 and its internal structure are clearly shown in fig. 13. In this embodiment, the ejection tube 234 has a cylindrical shape. However, the ejector tube 234 may have a hexahedral shape, and may have various shapes. Of course, a portion of the ejector tube 234 for rotating the ejector tube 234 should be cylindrical in shape.

The ejection tube 234 has an ejection flow path 236 inside and communicates with the communication flow path 218. The lower portion of the eject tube 234 has a rotation support 238, which is relatively rotatably inserted into the rotation support ring 216 of the lift case 214. The rotation support 238 has an outer diameter equal to or slightly smaller than an inner diameter of the rotation support ring 216 and is rotatable with respect to the rotation support ring 216. In order to rotate the ejector tube 234, the rotating support ring 216 is a portion that should be formed in a cylindrical shape.

A driven gear part 240 is formed around an outer surface of the rotation support part 238. The driven gear part 240 is a kind of rack part. The rotation driving gear 228 of the rotation motor 226 is engaged with and operated by the driven gear portion 240. By the driving of the rotation motor 226, the rotation driving gear 228 is engaged with the driven gear part 240 to operate, so that the ejection tube 234 is rotated. The driven gear part 240, the rotation drive gear 228, and the like are clearly shown in fig. 16. The rotation motor 226 is driven by the control unit 600. Therefore, the control unit 600 rotating the eject tube 234 or controlling the rotation of the eject tube 234 means that the control unit 600 rotates the eject tube 234 by driving the rotation motor 226.

An ejection discharge port 242 is formed around the outer surface of the ejection tube 234. The ejection discharge port 242 is formed only in a partial region of the outer surface of the ejection tube 234. This is to discharge the air flowing through the ejection flow path 236 more strongly in a specific direction. Therefore, the area where the ejection outlet 242 is formed is preferably less than half of the outer surface of the ejection tube 234. It is preferable that the ejection discharge port 242 is formed in a region of less than 180 degrees with respect to the center of the ejection flow path 236.

Further, a plurality of adjustment vanes 244 are provided inside the ejection flow path 236. The adjustment wing 244 adjusts the vertical direction of the air discharged through the ejection outlet 242. As shown in fig. 13, the adjustment wing 244 has a semicircular plate shape, and is adjusted in angle in the vertical direction by a separate drive source or manually.

In the illustrated embodiment, the additional discharge unit 200 having such a structure is also provided in the second space 24 with the same structure. In the additional discharge portion 200, the ejection tube 234 is not cylindrical but hexahedron such as a quadrangular prism or another shape. Here, it is necessary that the ejection tube 234 is formed in a shape to send the heat-exchanged air to a more distant desired position. If the ejection tube 234 is formed in a quadrangular prism shape, the ejection outlet 242 may be formed on one of four sides of the ejection tube 234.

The filter unit 300 is inserted into and removed from the lower portion of the center of the front surface of the housing 10 in the form of a drawer. The filter unit 300 is provided at the suction port 11 'formed at the bottom plate 11 to purify air passing through the suction port 11'.

The suction port 11' is formed at the bottom surface of the housing 10 opposite to the ground where the housing 10 is installed, and thus, an additional structure for shielding the filter unit 300 is not required. That is, when the housing 10 is disposed on the floor of the living room, the user cannot see the suction port 11 ', and thus, the user cannot easily access the suction port 11 ', without providing a structure for protecting the filter unit 300 at the suction port 11 '.

As shown in fig. 3, the filter unit 300 is inserted into and removed from an access opening (not denoted by a reference numeral) formed in a lower portion of the front plate 15. Therefore, the maintenance work for replacing the filter having the exhausted life can be easily performed in the filter unit 300.

As shown in fig. 17 and 18, the frame of the filter unit 300 is formed of a filter frame 301. The filter frame 301 has a flat hexahedral shape, in which a plurality of passing areas 302 are formed to pass through from top to bottom. The passing area 302 is a path through which air passes. In the embodiment shown, there are three pass-through regions 302. In a top view, the pass-through region 302 is in the shape of a regular quadrilateral. The pass-through region 302 is shaped and sized to prevent sagging of the filters 320, 330, 340 disposed therein. In the passage area 302, a first filter 320, a second filter 330, and a third filter 340, which will be described below, are stacked in this order.

The front side of the filter frame 301 is formed by a front wall 303. The front wall 303 forms a partial appearance of the housing 10 when the filter unit 300 is arranged in the housing 10. A handle 303' is provided at the center of the lower end of the front wall 303. The handle 303' is a portion for a user to grasp when pulling out and inserting the filter unit 300 through the entrance.

The side walls 305 extend rearward from both ends of the front wall 303. A rear wall 307 connects the rear ends of the side walls 305 on both sides. The rear wall 307 extends parallel to the front wall 303. A filter partition wall 309 connects the front wall 303 and the rear wall 307 to delimit the passage area 302. The passage area 302 vertically penetrating the filter frame 301 is divided into a plurality of areas by the filter partition walls 309.

At the lower end of the side wall 305 and filter partition wall 309 there is a mounting end 311. The mounting end 311 is a portion where an edge of a first filter 320 described below is mounted. The mounting end 311 need not be formed on the side wall 305 and the filter partition wall 309, and may be formed on the front wall 303 and the rear wall 307, for example. Of course, the mounting end 311 may be formed on the side wall 305, the filter partition wall 309, the front wall 303, and the rear wall 307. However, in order to avoid narrowing the flow cross-sectional area of the air flow, it is preferable in the embodiment shown in the drawings to form only on the mutually opposed walls.

Support ribs 313 protruding rearward of the filter frame 301 are formed at the upper and lower ends of the rear wall 307, respectively. The support rib 313 functions to support the filter frame 301 inside the doorway to prevent the filter frame 301 from falling off randomly when the filter frame 301 is pulled out from the doorway to such an extent that the filter can be replaced. Of course, the filter frame 301 may be held by the housing 10 by the rail assembly 350 described below, but the filter frame 301 is maintained in a state of being extended from the housing by the support ribs 313.

Next, the filters 320, 330, 340 provided in the passage area 302 will be described. A first filter 320 is disposed in the pass-through region 302. The first filter 320 is a prefilter, and functions to filter dust. The filter part 322 of the first filter 320 is a mesh structure to filter dust. A housing case 324 is integrally formed with the first filter 320. The receiving case 324 is formed as a quadrangular wall body surrounding the edge of the filter part 322.

Thus, a predetermined housing space 325 is formed above the filter unit 322. A second filter 330 and a third filter 340, which will be described below, are provided in the housing space 325. The height of the housing case 324 is more protruded than that of the third filter in a state where the second filter 330 and the third filter 340 are stacked on the filter part 322 of the first filter 320. In this regard, reference may be made to fig. 19. With this structure, the worker can easily separate the housing case 324 from the passage area 302 of the filter frame 301.

A second filter 330 is provided in the housing 325. The second filter 330 has a flat hexahedral shape corresponding to the shape of the receiving space 325. The second filter 330 uses a high efficiency air (HEPA) filter. Therefore, the second filter 330 removes dust in the air by blocking of fibrous tissues, particle sedimentation by impact and gravity, brownian motion of particles, adsorption by static electricity, and the like according to the size of particles.

In the receiving space 325, the third filter 340 is disposed above the second filter 330. The third filter 340 uses a deodorizing filter. The deodorizing filter mainly uses an activated carbon component in many cases. The third filter 340, which is a deodorizing filter, removes odor such as malodor smell in the air.

In order to allow the filter frame 301 to be drawn in and out of the housing 10, rail assemblies 350 are provided between both sides of the filter frame 301 and corresponding inner surfaces of the housing 10. The structure of the track assembly 350 is best shown in fig. 20.

The rail assembly 350 has a frame fixing portion 352 fixed to a side surface of the filter frame 301. The frame fixing portion 352 extends long in the front-rear direction, and has movement guide rails 354 at upper and lower ends, respectively. A housing fixing portion 356 is provided corresponding to the frame fixing portion 352. The housing fixing portion 356 is fixed inside the housing 10. The housing fixing portion 356 has fixing guide rails 358 at upper and lower ends thereof, respectively. The fixed guide rail 358 is opposite to the moving guide rail 354. In the present embodiment, a fixed guide rail 358 is provided to face the inner surface of the movement guide rail 354.

A connection rail 360 is movably provided at an inner side of the frame fixing part 352. A plurality of ball support pieces 362 are respectively provided at upper and lower ends of the connection rail 360, and a ball 364 is rotatably provided at the ball support pieces 362, and the ball 364 rotates while contacting the moving guide rail 354 and the fixed guide rail 358, so that the moving guide rail 354 smoothly moves. While the connection rail 360 moves along the frame fixing part 352, a portion thereof may protrude from the frame fixing part 352 so that the movement stroke of the filter frame 301 becomes relatively long.

As shown in fig. 4 and 21, a dust collector 370 for removing dust and foreign substances in the filters 320 and 330 is provided at the suction port 11' formed in the bottom plate 11 of the housing 10. The dust catcher 370 is provided on the bottom plate 11 to reciprocate linearly along the entire area of the suction port 11'. The duster 370 may be considered a vacuum cleaner. The appearance and frame of the precipitator 370 is formed by a precipitator body 317. The portion of the precipitator body 317 opposite the base plate 11 is a bottom 372. Preferably, the bottom 372 has a predetermined area, is substantially planar, and has a magnitude the same as or slightly greater than that of the suction port 11'.

As shown in fig. 22, the bottom 372 has a dust suction port 373. The duster suction port 373 is formed on both sides with reference to a portion through which a duster rail 380 described below passes. Of course, when the duster rails 380 are disposed at positions corresponding to both end edges of the suction port 11' of the base plate 11, one of the duster suction ports 373 may be disposed. However, if the size of the duster 370 becomes large, the weight may become heavy, and therefore, it is preferable that the duster 370 be made small by making the duster rail 380 cross the suction opening 11'. Further, if the plurality of the precipitator suction ports 373 are provided, the flow sectional area of each of the precipitator suction ports 373 becomes small, so that it is possible to prevent the suction force from leaking due to the sagging of the precipitator 370, or the like.

As shown in fig. 22, elastic bristles 375 are disposed around the periphery of the suction port 373 of the dust collector. The elastic bristles 375 rub against the filter surface as if a broom were sweeping the dust so that the dust on the filter surface is well received into the duster suction port 373. The elastic bristles 375 are densely arranged around the dust collector suction port 373 to prevent the suction force generated at the dust collector suction port 373 from leaking.

The elastic brush 375 is formed by cutting an elastically deformable material into a linear shape having a predetermined diameter and a predetermined length. Of course, the elastic bristles 375 may be made of a natural material having a certain strength and a certain degree of elastic deformation, such as wool. The elastomeric bristles 375 form a wall surrounding the duster intake 373. Preferably, not one row but a plurality of rows are arranged to eliminate the leakage of the suction force.

An air outflow hole 377 is formed at one side of the outer surface of the dust collector body 371. The air outflow holes 377 are preferably disposed at positions relatively separated from the dust collector suction port 373, and the air outflow holes 377 are portions for discharging air to the outside after removing dust or foreign substances from the air sucked into the dust collector suction port 373. Of course, it is also possible to collect the dust not inside the dust catcher 370 but in a dust box at another location connected to the air outflow opening 377 by a discharge hose.

The cleaner body 371 has a structure for moving the cleaner 370 and a structure for sucking dust therein, and a structure for sweeping dust falling on the surface of the filter 310, such as a stirrer, at the cleaner suction port 373.

The cleaner rail 380 is provided on the bottom surface of the bottom plate 11 so as to cross the suction port 11'. The duster 370 makes a straight reciprocating motion along the duster rail 380.

In the present invention, the dust collector 370 is disposed on the bottom surface of the bottom plate 11 of the housing 10 and is not shielded by other structures. Therefore, the suction port 11' is directly exposed without being blocked by other structures. With this configuration, air in the living room flows smoothly through the air flow path 102.

The dust collector 370 is not covered by other structures, and the air flows smoothly to the suction port 11'. However, if the precipitator 370 is supported only by the precipitator rail 380, sagging may occur at a certain position due to the self-weight of the precipitator 370. However, the elastic bristles 375 can be always in close contact with the surface of the first filter 320 in an elastically deformed state, and thus, the leakage of suction force can be prevented. That is, in the position where the elastic brush 375 is sagged by the gravity of the dust collector 370, although the degree of the elastic deformation is reduced, the suction force does not leak as long as the state of being closely attached to the surface of the first filter 320 is maintained.

The bottom 372 of the dust catcher 370 faces the surface of the first filter 320, and the elastic bristles 375 around the suction port 373 elastically deform to closely contact the surface of the first filter 320. If the length of the elastic bristles 375 is excessively long, a leakage of suction force may occur through gaps between the elastic bristles 375, and thus, the distance between the surface of the first filter 320 and the bottom 372 of the duster 370 should be a distance below a prescribed value.

Since the filter unit 300 is located inside the suction port 11' of the housing 10 and the dust collector 370 is located at the bottom surface of the bottom plate 11 of the housing 10, there is a certain distance therebetween. To reduce this distance, the surface of the first filter 320 is protruded to be close to the bottom 372 of the dust collector 370 by providing a step at the periphery of the first filter 320.

The humidifying structure is explained with reference to fig. 24 to 29. The air inlet pipe 401 penetrates the first partition wall 19 and communicates with the air flow path 102. The air inflow pipe 401 extends toward the inside of the first space frame 202. A part of the air in the air flow path 102 is transferred to the air inflow pipe 401. Here, the air flowing into the air inflow pipe 401 is air that has passed through the filter unit 300 but has not passed through the heat exchanger 104. Therefore, the air in the living room is purified by the filter unit 300 and then transferred to the air inflow pipe 401.

The inflow fan section 403 is connected to the air inflow pipe 401. A fan (not shown) is provided inside the inflow fan section 403. The fan is driven to suck the air in the air flow path 102 into the air inflow pipe 401.

The air pressurized by the inflow fan section 403 flows through the air transfer pipe 405, and the steam generator 407 is connected to the air transfer pipe 405. The steam generator 407 heats water supplied from a water tank 419 described below to generate steam. In the present embodiment, steam is generated using the heated steam generator 407 for humidification, or water molecules may be vaporized by ultrasonic waves. That is, various humidification means may be used instead of the steam generator 407.

The steam generator 407 has a first exhaust duct 409. The steam generated in the steam generator 407 and the air transferred through the air inflow pipe 401 are discharged in a mixed state from the first discharge pipe 409. The first discharge pipe 409 is connected to the connection pipe 204. The humidified air flowing through the first discharge pipe 409 is transferred to the connection pipe 204, sequentially flows through the vertical flow path 210, the communication flow path 218, and the ejection flow path 236, and is then discharged into the indoor space through the ejection outlet 242.

As shown in fig. 25, in the steam generator 407, the second discharge pipe 411 is arranged in a different direction from the first discharge pipe 409. Of course, the second discharge pipe 411 is not necessarily provided. The second discharge pipe 411 transfers the humidified air to the humidification connection pipe 413. The humidification connection pipe 413 communicates with the vertical flow path 210 of the vertical pipe 208 located in the second space 24. The humidifying connecting pipe 413 is located in a back space 13s formed between the back plate 13 and a wall surface. Here, since the first discharge pipe 409 and the second discharge pipe 411 each have a humidification damper (not shown), the air discharged for humidification can be controlled.

The frame space 203 formed in the first space frame 202 has a tank mount 415. A water tank 419 is attached to the water tank mount 415. In order to transfer the water supplied from the water tank 419 to the steam generator 407, a humidifying pump 417 is provided adjacent to the water tank mount 415.

The water tank mount 415 may tilt the water tank 419. The tank mount 415 operates to extend the upper end of the tank 419 to the outside in the frame space 203. This is to allow the water tank 419 to easily go out into and out of the frame space 203.

As shown in fig. 27, the tank holder 415 has a bottom frame 421. The base frame 421 is a portion where components for constituting the water tank mount 415 are mounted and supported. The bottom frame 421 is disposed at the bottom of the frame space 203 in the first space frame 202. A pair of guide posts 423 are respectively vertically provided at the rear ends of the bottom frame 421. The space between the guide posts 423 has a guide rail 425 and a guide groove 427. The guide tracks 425 are integrally formed on the inner surfaces of the pair of guide posts 423 facing each other, and a space between the guide tracks 425 is a wire guide 427. The guide track 425 has a curved shape with a predetermined radius of curvature.

A water storage portion 429 is convexly arranged on the top surface of the bottom frame 421. A water storage space 431 is formed inside the water storage portion 429 to temporarily store water supplied from the water tank 419.

A water storage top plate 433 is provided on the top surface of the water storage 429 of the bottom frame 421. The water storage portion top plate 433 plays a role of shielding the water storage space 431. A sealing member (not shown) is provided between the water storage top plate 433 and the bottom frame 421 to prevent water leakage. The top plate 433 of the water storage unit has rotary center holes 435 on both sides thereof. The rotation center hole 435 becomes a center of inclination of an inclination table 449 described below.

The rotation center hole 435 is formed at a side of a mounting wall 437 formed to protrude from the water storage portion top plate 433. The mounting wall 437 serves to support the tilting table 449 in a state where the tilting table 449 is not tilted. The mounting walls 437 are symmetrically formed at both sides of the water storage part inlet 441, which will be described below, respectively.

A tilt stop 439 extends from the mounting wall 437. The inclined stopper 439 is inclined lower as it approaches the front end of the water storage top plate 433. The tilt stopper 439 functions to support the lower surface of the tilting table 449 when the tilting table 449 tilts.

A water storage inlet 441 is formed through the water storage top plate 433. The water storage inlet 441 is an inlet of the water storage space 431. The water storage inlet 441 has a valve opening 443. The valve opening 443 functions to open the valve of the water tank 419.

The structure of the water storage top plate 433 may be integrally formed with the bottom frame 421. For example, the rotation center hole 435 may be formed at both side surfaces of the water storage portion 429 of the bottom chassis 421.

A rotation center shaft 447 of the rotation center member 445 is provided at the rotation center 435. The rotation center member 445 is fixed to an inclined table 449 described below, and the rotation center shaft 447 is positioned in the rotation center hole 435. Therefore, the rotation center hole 435 becomes a rotation center of the tilting table 449.

A tilting table 449 is tiltably provided at the base frame 421. The inclined table 449 may be in a state in which the top surface is horizontal and an inclined state in which the inclination is inclined downward toward the front end. This state is achieved by rotating the tilting table 449 by a predetermined angle about the rotation center axis 447.

The driving force for tilting the tilting table 449 is transmitted to the tilting table 449 via a tilting rack portion 451. As shown in fig. 28, the tilt rack portion 451 is located at the rear end of the tilt table 449. The entire shape of the inclined rack portion 451 is a curved line having a predetermined radius of curvature. The inclined rack portion 451 is formed in a curved shape so as to be interlocked with the guide rail 425 of the base frame 421. The rack 453 is formed on the outer surface of the inclined rack portion 451. The rack 453 is engaged with an output gear 467 of a tilt reducer 463 described below to operate.

Both side surfaces of the inclined rack portion 451 have curved connecting passages 455. The guide rail 425 of the base frame 421 is disposed at the connection passage 455 to be guided.

A water storage cover 457 is provided on the inclined table 449. A water supply hole 459 is formed in the water storage part cover 457, and a bellows-shaped connection pipe (not shown) is connected between the water supply hole 459 and the water storage part inlet 441 to allow water to be transferred to the water storage space 431 without leakage. That is, water flowing out of the water tank 419 installed at the inclined stand 449 is transferred to the water storage space 431 through the water supply hole 459.

A driving force for operating the tilting table 449 is provided by a tilting drive source 461 shown in fig. 26 and 29. The tilting drive source 461 may use an electric motor. The tilting drive source 461 is disposed at the rear of the base frame 421. A tilt reducer 463 for reducing and transmitting the driving force of the tilt driving source 461 is connected to the output shaft of the tilt driving source 461. The speed reducer housing 465 forms an appearance of the inclined speed reducer 463, and a plurality of gears are provided in the speed reducer housing 465. The last gear in the gear train of the tilt reducer 463 is an output gear 467. The output gear 467 is engaged with the rack 453 of the tilting table 449 to operate.

In addition, the front surface of the housing 10 has a proximity sensor 470. The proximity sensor 470 serves to identify a user who replaces the water tank 419. That is, when the user approaches the proximity sensor 470 in front of the first moving plate 16, the user is recognized and the first moving plate 16 is automatically opened, the tilting table 449 of the tank mount 415 is tilted, and the upper end of the water tank 419 protrudes from the frame space 203. Here, a button may be used instead of the proximity sensor 470. That is, any sensing means may be employed instead of the proximity sensor 470 as long as the intention of replacing the water tank 419 can be recognized.

The structure inside the machine chamber 500 will be described below with reference to fig. 30 and 31. A second space frame 202' is provided in the second space 24. The second space frame 202' has a similar structure to the first space frame 202, includes a vertical pipe 208 constituting the additional discharge unit 200, and is provided with an ejection pipe 234 so as to be movable up and down. The structure of the additional discharge unit 200 is the same as that of the first space frame 202.

A machine room 500 is formed at one side of the second space frame 202'. The machine room 500 is a part of the frame space 203 including the first space frame 201. The machine room 500 is located in the remaining region except the region where the vertical pipe 208 is formed in the second space frame 202'. A top separation plate 501 constituting a top plate of the machine chamber 500 is located at a predetermined distance from the top plate 14 of the casing 10, and a bottom separation plate 501' facing the top separation plate 501 and forming a bottom plate of the machine chamber 500 is located at a predetermined distance from the bottom plate 11 of the casing 10.

A drain pump 502 is provided on the bottom surface of the bottom separation plate 501'. As shown in fig. 30, the drain pump 502 is located at a lower position than the bottom of the drain pan 108. That is, the portion of the drain pump 502 to which the connection hose 504 is connected is located at the same height position or a lower position as the extended surface of the bottom of the drain pan 108.

Therefore, in the connection hose 504 that connects the drain pan 108 and the drain pump 502 to transfer the condensed water to the drain pump 502, the end connected to the drain pan 108 is located at a higher position than the end connected to the drain pump 502. This is to allow the condensed water to naturally move by its own weight through the connection hose 504. In the illustrated embodiment, the connection hose 504 appears to extend through a side of the drain pan 108, however, the bottom surface of the drain pan 108 and the corresponding inner side surface of the connection hose 504 are at the same height. Alternatively, the connection hose 504 is located at a position lower than the bottom of the drain pan 108 and communicates with the inside of the drain pan 108. The connection hose 504 may penetrate the bottom of the drain pan 108 and be connected to the drain pan 108. The bottom of the drain pan 108 is preferably formed to be inclined such that the lower the side closer to the side connected with the connection hose 504.

In the present invention, the connection hose 504 is generally divided into an upper end 505, a connection portion 505', and a lower end 505 ″. The upper end portion 505 is connected to the drain pan 108, and has a predetermined height difference from the lower end portion 505 ″. The connecting portion 505' connects the upper end portion 505 and the lower end portion 505 ″. The lower end 505 "is a portion connected to the drain pump 502 and is located at the lowest position in the connection hose 504. The upper end portion 505 may be absent from the connection hose 504, and the connection portion 505' is directly connected to the bottom of the drain pan 108 to communicate with the drain pan 108.

It is preferable that the drain pump 502 is operated such that the drain pump 502 does not need to suck all of the condensed water filled in the lower end portion 505 ″ of the connection hose 504, but the condensed water remains in the lower end portion 505 ″ or the connection portion 505'.

A drain hose 506 is connected to the drain pump 502. The drain hose 506 serves to transfer the condensed water pressurized by the drain pump 502 to the outside. The maximum height H of the discharge hose 506 is at least 400 mm. The discharge hose 506 extends through the back plate 13 of the housing 10 to the outside. Preferably, the highest position among the positions of the hose through holes 13' for passing the discharge hose 506 through the back plate 13 (the maximum height H of the discharge hose 506) is located at the topmost end of the back plate 13. Thus, the structure for discharging the condensed water inside the case 10 to the outside is easily designed.

The reason why the maximum height H of the drain hose 506 is set to at least 400mm is that the condensed water can flow in the section of the drain hose 506 after the maximum height H by the gravity of the condensed water. That is, the drain hose 506 drains the condensed water by flowing by its own weight, regardless of the pressurizing force of the drain pump 502, from the portion extending from the machine chamber 500 to the outside of the casing 10.

A supply hose 510 is provided in the machine chamber 500. The supply hose 510 supplies air containing oxygen or negative ions, for example, to the air flow path 102. In this manner, various modes of operation are provided for users within the living space. The supply hose 510 is provided to penetrate through a portion of the second space frame 202 ' corresponding to the second partition plate 19 ' and one hose through hole 13 ' in the back plate 13. Therefore, the supply hose 510 communicates the supply source on the outdoor unit side with the air flow path 102.

The operation of the air management device of the present invention having the above-described configuration will be described in detail below.

First, heat exchange of air of an indoor space while passing through the heat exchanger 104 in the air management device of the present invention will be described with reference to fig. 32. By driving at least one of the driving fans 130, 130 ', 130 ″, the indoor air is sucked through the suction port 11'. The indoor air moves to a space between the indoor floor and the bottom plate 11 of the case 10 and flows to the air flow path 102 of the case 10 through the suction port 11'.

In this process, dust and foreign substances, odor, and the like in the air are removed while the air passes through the filter unit 300. The air having passed through the filter unit 300 passes through the heat exchanger 104 after flowing along the air flow path 102. The air sucked from the suction port 11' is caused to flow toward a position relatively near the rear end of the air flow path 102 by the inlet guide 110. Since the guide inclined surface 110' of the inlet guide 110 is inclined upward toward the back plate 13, the air passing through the filter unit 300 is mainly guided toward the back plate 13. This is because the space between the guide inclined surface 110' and the filter unit 300 becomes wider as it gets closer to the back plate 13.

The air flowing toward the rear end of the air flow path 102 located near the back plate 13 flows through the heat exchanger 104 by the operation of the driving fans 130, 130 ', 130 ″, and then enters the fan spaces 124, 124 ', 124 ″ in which the air guide portions 120 of the driving fans 130, 130 ', 130 ″, which are being driven, are provided.

At this time, the upper guide 112 guides the air flowing through the air flow path 102 and transfers the air to the heat exchanger 104. In particular, the upper guide 112 prevents air from flowing over the upper portion of the heat exchanger 104, thereby allowing all air flowing in the air flow path 102 to pass through the heat exchanger 104.

The air passing through the heat exchanger 104 enters a specific fan space 124, 124 ', 124 "by being driven by each driving fan 130, 130', 130" and the flow path is branched. The air flows out of the outflow ports 128 of the fan spaces 124, 124 ', 124 ″ and then flows toward the corresponding discharge ports 15' -1, 15 '-2, 15' -3. If the vanes 141, 142, 143 of the corresponding discharge ports 15 ' -1, 15 ' -2, 15 ' -3 are opened at a predetermined angle, the air is guided by the vanes 141, 142, 143 and discharged into the indoor space.

In the present invention, air is discharged from the discharge ports 15 '-1, 15' -2, 15 '-3 by the operation of the driving fans 130, 130', 130 ″. In this case, the discharge of air through the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 can be independently set according to whether or not a specific driving fan is driven.

For example, only the first driving fan 130 may be driven to open the first blades 141 and discharge the heat-exchanged air only through the first discharge port 15' -1. Alternatively, only the second driving fan 130 'may be driven to open the second blades 142 and discharge the heat-exchanged air only through the second discharge port 15' -2. Alternatively, only the third driving fan 130 ″ may be driven, and the third blade 143 may be opened to discharge the heat-exchanged air only through the third discharge port 15' -3.

Of course, at least two or more of the driving fans 130, 130', 130 ″ may be combined to drive. At this time, the air is discharged by operating the blades 141, 142, 143 corresponding to the driven fans 130, 130', 130 ″, respectively.

Further, by making the rotation angles of the blades 141, 142, and 143 different, the distance of air discharged from the discharge ports 15 ' -1, 15 ' -2, and 15 ' -3 can be independently controlled. Thus, various air management can be performed on the front area of the housing 10 according to whether the driving fans 130, 130', 130 ″ are operated and the rotation angles of the blades 141, 142, 143. In the illustrated embodiment, the discharge of air is controlled by adjusting the vertical angles of the vanes 141, 142, 143, but when each of the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 is viewed from the front, a flap may be additionally provided to discharge air in the left-right direction.

In the present invention, the operation of the air management device is exemplified. Assuming that three users are seated at the front of the housing 10 at positions corresponding to the respective discharge ports 15 '-1, 15' -2, 15 '-3, the air management can be performed by setting different driving of the driving fans 130, 130', 130 ″ and rotation angles of the blades 141, 142, 143 according to the requirements of each user.

The driving of the driving fans 130, 130', 130 ″, the opening of the blades 141, 142, 143, and the adjustment of the angle may be combined in various ways. The speed of the discharged air is made different by setting different rotational speeds of the driving fan. By such various combinations, air is discharged from each of the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 in various patterns.

Fig. 33 illustrates, as an example, a case where all the driving fans 130, 130 ', and 130 ″ are driven and all the blades 141, 142, and 143 are operated to open all the three discharge ports 15' -1, 15 '-2, and 15' -3, thereby discharging air into the indoor space. At this time, since the air does not flow out to the ejection pipe 234 through the branch flow path 129 formed in the air guide portion 120, the air is prevented from flowing to the connection pipe 204 by closing the damper 206. Therefore, the airflows generated by the first and third driving fans 130 and 130 ″ do not flow into the branch flow path 129, but flow into the first discharge port 15 '-1 or the third discharge port 15' -3 through the corresponding outflow port 128.

The opening and the angle adjustment of the vanes 141, 142, 143 are performed by driving the driving motors 141 ', 142 ', 143 '. The rotation of the rotation center piece 145 of the vane 141, 142, 143 connected to the output shaft of the driving motor 141 ', 142 ', 143 ' rotates the vane 141, 142, 143. The output shafts of the driving motors 141 ', 142 ', 143 ' are operated at a speed and torque set by the speed reduction part therein. The rotation angle of the vanes 141, 142, 143 is set according to the degree of operation of the output shafts of the drive motors 141 ', 142 ', 143 '. Here, the operation mode is set in advance, and the rotation angle of the blades 141, 142, and 143 can be set by the user selecting the corresponding operation mode. By such operation, the heat-exchanged air discharged from the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 is directly or indirectly delivered to a specific user. For example, if the heat-exchanged air is discharged to the front of the discharge ports 15 ' -1, 15 ' -2, 15 ' -3, the heat-exchanged air is directly transmitted to the user in front of the casing 10. If the installation angles of the blades 141, 14, and 143 are adjusted to discharge the heat-exchanged air from the discharge ports 15 ' -1, 15 ' -2, and 15 ' -3 to the front upper portion of the housing 10, the air is not directly transferred to the user but indirectly transferred.

Next, the operation of discharging air through the ejection outlet 242 of the ejection tube 234 will be described. The heat-exchanged air is transferred to the indoor space through the additional discharge part 200 relatively more than through the discharge ports 15 ' -1, 15 ' -2, 15 ' -3. The eject pipe 234 ascends toward the upper portion of the housing 10 and rotates, and at the same time, delivers air to a desired position. Therefore, air can be delivered to a wider and more remote area. That is, the heat-exchanged air may be transferred to other spaces adjacent to the space where the air management device is disposed. For example, when the air management device of the present invention is being used in a living room, air flowing from the pop-up tube 234 may be delivered to an adjacent kitchen.

As shown in fig. 34 and 35, air is discharged from the ejection tube 234. In order to discharge the air into the indoor space through the ejection discharge port 242 of the ejection pipe 234, the air should be supplied to the ejection pipe 234 through the branch flow path 219. For this, the damper 206 should open the branch flow path 219 to communicate the branch flow path 219 and the connection pipe 204 with each other.

And, at least one of the first driving fan 130 and the third driving fan 130 ″ drives the fan to operate. That is, the heat-exchanged air is discharged through the ejection tubes 234 on both sides, but the air may be discharged through only one ejection tube 234. Fig. 34 shows only the structure related to the first driving fan 130 for convenience of illustration. As shown in fig. 35, the two ejector pipes 234 rise toward the upper portion of the housing 10 and discharge air. Of course, fig. 35 also shows a case where the second blades 142 of the second discharge port 15 '-2 are operated to discharge air by the driving of the second driving fan 130'. However, the second vane 142 may be closed as in the case of the first vane 141 or the third vane 143, and at least one of the two ejection pipes 234 may be operated to discharge air.

Next, the air is discharged through the additional discharge unit 200 on the left side of the casing 10. The first driving fan 130 is driven to open the damper 206, and the air heat-exchanged in the heat exchanger 104 flows into the branch flow path 219 by the first driving fan 130. The air flowing through the branch flow path 219 flows through the open damper 206 and then flows to the connection flow path 205 of the connection pipe 204. The connection channel 205 communicates with the vertical channel 210 of the vertical pipe 208, and the air passing through the connection channel 205 flows into the vertical channel 210.

The eject pipe 234 is lifted up toward the upper portion of the housing 10 during use, and the lift rack portion 212 and the lift driving gear 232 of the lift motor 230 provided in the lift case 214 lift the eject pipe 234. That is, when the elevation motor 230 rotates in one direction, the elevation driving gear 232 rotates and moves along the elevation rack portion 212, so that the elevation housing 214 operates. As shown in fig. 34, in order to discharge the heat-exchanged air through the ejection pipe 234, the ejection pipe 234 is raised, and the ejection pipe 234 is raised toward the upper portion of the housing 10.

As shown in fig. 35, the ejector pipe 234 can be lifted in the direction of arrow a and rotated in the direction of arrow B. That is, the ejection tube 234 is raised and rotated after the raising, and the ejection outlet 242 is directed in a desired direction. Fig. 15 and 16 show a structure related thereto.

The rotation motor 226 provided in the lift case 214 is driven to rotate the eject pipe 234. When the rotation motor 226 is driven, the rotation driving gear 228 rotates and is interlocked with a driven gear 240 formed at a rotation supporting portion 238 of the eject pipe 234, so that the eject pipe 234 rotates. Since the ejection pipe 234 rotates in a raised state, the heat-exchanged air is easily sent to a position where a user wants to deliver the air.

At this time, when the outer surface of the ejector tube 234 is viewed from the front, the ejector discharge port 242 is formed in a region of not more than half of the outer surface of the ejector tube 234, and the air transferred to the ejector flow path 236 is discharged to the outside in a direction in which the ejector discharge port 242 of the ejector tube 234 faces. The ejector tube 234 is rotatable 360 degrees. However, since the back surface of the housing 10 is provided on a wall surface adjacent to the living space, the ejection pipe 234 discharges air substantially to a rotation region of about 180 degrees. For example, when the user is in front of the discharge ports 15 ' -1, 15 ' -2, 15 ' -3, the ejection discharge port 242 is rotated to face the direction of the user, thereby discharging air to the user; if air is to be delivered to another space, the ejection outlet 242 is rotated to the direction in which the corresponding space is located, and the ejection outlet 242 discharges the air in a state of being directed to the corresponding space.

The ejection tube 234 may eject air while rotating at a predetermined angle, in addition to ejecting air with the ejection outlet 242 directed in a specific direction. That is, when the ejection outlet 242 of the ejection tube 234 is viewed from the front, the air can be discharged by rotating back and forth in the left and right directions within a predetermined angle range. Further, the ejection flow path 236 includes a regulating fin 244 for vertically regulating the direction of the air discharged from the ejection outlet 242, and the transfer distance of the heat-exchanged air can be adjusted by vertically regulating the direction of the air discharged from the ejection outlet 242.

The eject drive fan 224 may be selectively operated when air is discharged through the eject tube 234. To blow the air discharged through the ejector pipe 234 farther, the ejector driving fan 224 pressurizes the air in the communication flow path 218. The first or third driven fans 130 ", 130" alone may be driven to exhaust the air flow, and the pop-up driven fan 224 may be activated to pressurize the air as it is blown further to exhaust the air through the pop-up exhaust 242.

If the heat-exchanged air is discharged from the first to third discharge ports 15 ' -1, 15 ' -2, 15 ' -3 while using the two-sided ejection tubes 234, air management can be simultaneously performed on different conditions for more users in front of the housing 10. This is facilitated by the supplemental drains 200 being located adjacent to both ends of the housing 10. That is, the first to third discharge ports 15 ' -1, 15 ' -2, 15 ' -3 and the additional discharge portion 200 at the upper end of the center of the front surface of the housing 10 are operated in cooperation, so that air management can be performed on more users sitting side by side in independent conditions.

The air is purified while passing through the filter unit 300 because the air delivered to the suction port 11' passes directly through the first filter 320. This is because no shielding structure is additionally provided at the suction port 11'. That is, the suction port 11' is opposed to the floor of the living room and is not directly visible to the user, so that it is not necessary to provide a shielding structure.

Since the first filter 320, the second filter 330, and the third filter 340 are sequentially stacked in the filter frame 301, the air sequentially passes through the first filter 320, the second filter 330, and the third filter 340 to remove dust, fine dust, and odor. The air passing through the filter unit 300 enters the air flow path 102.

In the course of the air management device being operated while the air in the living room space is repeatedly sucked into and discharged from the air management device, dust and odor components are collected at the first filter 320, the second filter 330, and the third filter 340 of the filter unit 300. In order to maintain the performance of the filter unit 300 above a certain level, the dust separator 370 is put into operation. The duster 370 is disposed at a side region separated from the suction port 11 'in the lower surface of the base plate 11, and moves along the duster rail 380 and passes through the suction port 11' region when receiving a running signal.

The dust collector 370 sucks dust and foreign materials through the dust collector suction port 373 while passing through the suction port 11' region. That is, dust and foreign substances attached to the filter 320 are sucked into the duster suction port 373 by the suction force of the duster 370. By such an action, dust and foreign substances on the filter 320 are removed, and particularly, the performance of the first filter 320 is improved.

Further, since the dust catcher 370 has a predetermined weight and tends to fall toward the floor of the living room by the weight, the middle portion of the dust catcher rail 380 may hang down by the weight. Thus, the dirt catcher 370 is located in the middle portion of the dirt catcher rail 380, possibly furthest from the filter 320.

However, since the elastic bristles 375 surround the duster suction port 373 of the duster 370, even if the distance between the surface of the filter 320 and the duster 370 is changed, the suction force does not leak at the duster suction port 373. This is because the elastic brush 375 surrounds the dust collector suction port 373 and maintains its tip in close contact with the surface of the filter 320 in an elastically deformed state. Even if the distance between the surface of the filter 320 and the dust collector 370 is changed, only the degree of elastic deformation of the elastic bristles 375 is changed.

The cleaner 370 cleans the filter 320 while reciprocating linearly along the cleaner rail 380, and after the cleaning of the filter 320 is completed, is again located at a position apart from the suction port 11' in the lower surface of the bottom plate 11.

In addition, in order to replace the filter 320, 330, 340, the filter frame 301 is pulled out from the housing 10. When the user pulls out by grasping the handle 303', the filter frame 301 is removed from the housing 10 like a drawer. That is, the rail assembly 350 operates to move the filter frame 301 out to the front of the housing 10. In this regard, please refer to fig. 36.

When the filter frame 301 is moved out to the front of the housing 10, the support rib 313 of the filter frame 301 at the rear end contacts the inner side of the doorway, and the rear end of the filter frame 301 is supported so that the front end of the filter frame 301 does not fall down. Of course, since the rail assembly 350 is connected to both the filter frame 301 and the housing 10, the filter frame 301 is not removed at will.

In this state, when the housing case 324 is lifted, the second filter 330 and the third filter 340 in the housing space 325 are taken out from the filter frame 301 together with the first filter 320. In this manner, all of the filters 320, 330, 340 in the three pass-through areas 302 are removed and can be serviced.

By maintenance, a new filter 320, 330, 340 is reinstalled in the pass-through area 302 of the filter frame 301. That is, the second filter 330 and the third filter 340 are stacked in order in the housing space 325 of the housing case 324, and then disposed in the passage area 302. Thereafter, the filter frame 301 is pushed into the housing 10.

In addition, discharging the humidified air through the ejector pipe 234 may generally include the following two cases. First, only humidification can be independently performed without heat exchange by the heat exchanger 104. Second, humidification may be additionally performed for all heating operation modes. In the present invention, the humidified air flows and is discharged through the connection pipe 204, the vertical pipe 208, and the ejection pipe 234, and therefore, the additional discharge unit 200 must be used in the humidification operation.

First, when only humidification is performed independently, the inflow fan section 403 is operated, and the air in the air flow path 102 is sucked through the air inflow pipe 401. The inflow fan portion 403 blows air pressurized by a fan to the steam generator 407 through the air transfer pipe 405. In the steam generator 407, steam generated by heating the water transferred from the water tank 419 is mixed with air. The air thus humidified may be transferred through the first discharge pipe 409 or the second discharge pipe 411. When the humidified air is discharged through only one of the ejection tubes 234, only the corresponding discharge tubes 409 and 411 are opened.

When the humidified air is discharged through the ejection tube 234 on the left side of the casing 10, the first discharge tube 409 is opened to allow the air to flow into the connection flow path 205 of the connection tube 204. At this time, the damper 206 preferably closes the branch flow path 219.

Fig. 37 shows a case where the humidifying operation is performed in a state where the air that has been heat-exchanged is not transferred to the connection flow path 205 because the branch flow path 129 is closed and the first driving fan 130 is not operated. At this time, the humidified air flowing out of the first discharge pipe 409 flows through the connection flow path 205 and the vertical flow path 210, is transferred to the pop-up flow path 236, and is discharged through the pop-up discharge port 242 in a state where the pop-up pipe 234 is raised toward the upper portion of the housing 10. Since the ejection tube 234 can rotate in a state of being raised toward the upper portion of the housing 10, humidified air can be delivered to a wider and more remote area. The ejection driving fan 224 is driven to pressurize the humidified air and transmit the air to a further place.

Then, humidification can be additionally performed for all heating operation modes. At this time, heat is exchanged in the heat exchanger 104, and the heat-exchanged air is discharged through at least one additional discharge unit of the discharge ports 15 ' -1, 15 ' -2, and 15 ' -3 and the additional discharge unit 200, and the humidified air is discharged to the indoor space through the connection flow path 205, the vertical flow path 210, and the pop-up flow path 236 in this order.

When the user selects the humidification mode, the fan of the inflow fan section 403 starts to operate. When the fan of the inlet fan section 403 is operated, a part of the air in the air flow path 102 flows into the air inlet pipe 401. The air flowing toward the air inflow pipe 401 is transferred toward the steam generator 407 through the air transfer pipe 405. The water transferred from the water tank 419 is supplied to the steam generator 407 to generate steam. The steam is mixed with the air transferred through the air transfer pipe 405 and transferred to the first and second discharge pipes 409 and 411.

The air supplied to the first discharge pipe 409 flows through the vertical flow path 210 along the connection flow path 205 of the connection pipe 204, passes through the communication flow path 218, and is discharged from the ejection flow path 236 and the ejection discharge port 242.

The humidified air transferred to the second discharge pipe 411 is transferred to the humidification connection pipe 413, passes through the humidification connection pipe 413, is transferred to the vertical flow path 210 of the vertical pipe 208 on the right side of the housing 10, and is discharged from the ejection pipe 234.

Water is required for humidification. Humidification water is supplied from the water tank 419. The water tank 419 is mounted on the water tank mount 415 of the frame space 203. As shown in fig. 38, when the user touches the proximity sensor 470, the proximity sensor 470 recognizes the user and moves the first moving door 16 to the left side.

Then, the tilting table 449 of the tank mount 415 is tilted downward toward the front of the case 10. When the tilting table 449 is tilted, the user easily takes the water tank 419 out of the frame space 203 or puts it into the frame space 203. After the water tank 419 is put in or taken out, the proximity sensor 470 is again touched to make the tilting table 449 in a horizontal state, and then the first moving door 16 closes the frame space 203.

Here, the operation of the tilting table 449 will be described in detail. As shown in fig. 39, the tilting table 449 is tilted in a state where the first movable door 16 is open, and is in a horizontal state in a state where the first movable door 16 is closed. For this, the tilting table 449 rotates about a rotation center 447 with respect to the base frame 421.

The tilting drive source 461 provides a driving force for rotating the tilting table 449. When the tilting drive source 461 is operated, the tilting reducer 463 is operated by the driving force of the tilting drive source 461, and the gear train of the tilting reducer 463 is operated. As shown in fig. 40, the output gear 467 of the tilt reducer 463 is engaged with the rack 453 of the tilt table 449 to rotate, and the tilt rack portion 451 on which the gear 453 is formed moves along the guide rail 425 of the base frame 421. The guide rail 425 is positioned in the connecting passage 455 of the tilt rack portion 451, and when the output gear 467 guides the movement of the tilt rack portion 451, the tilt table 449 rotates about the rotation center axis 447.

Thus, as the tilting table 449 rotates about the rotation center shaft 447, the tilting table 449 is selectively placed in a horizontal state or a tilted state. The water tank 419 is located at the inclined table 449, and the inclined table 449 is in an inclined state in a state where the first moving door 16 is opened, and the first moving door 16 is in a closable state when the inclined table 449 is shifted to a horizontal state.

In the water tank 419 mounted on the tilting table 449, the valve of the water tank 419 is opened by the valve opening 443, and water is delivered to the water storage space 431. The water in the water storage space 431 is transferred to the steam generator 407 by the humidification pump 417, heated, and vaporized.

When the working fluid and the air exchange heat in the heat exchanger 104, moisture in the air is condensed and adheres to the surface of the heat exchanger 104. As shown in fig. 41, if the diameter of the condensed water condensed in the heat exchanger 104 becomes large, the condensed water runs down the surface of the heat exchanger 104 and is collected in the drain pan 108.

The condensed water collected in the drain pan 108 flows toward the inside of the connection hose 504 by the weight. When the condensed water is transferred to the drain pump 502 through the connection hose 504, the drain pump 502 is operated to pressurize the condensed water. The pressurized condensate water rises along the inside of the drain hose 506. The condensed water flowing along the inside of the drain hose 506 may be pressurized by the drain pump 502 and then moved to the highest height H of the drain hose 506. After the condensed water is transferred to the highest height H of the drain hose 506, it flows and is drained by gravity.

In the present invention, since the end of the connection hose 504 connected to the drain pump 502 is lower than the end connected to the drain pan 108, the condensed water flows along the connection hose 504 to the drain pump 502 by gravity. Therefore, once the condensed water is generated, it is unconditionally moved from the drain pan 108 to the connection hose 504, and the drain pan 108 is filled after the connection hose 504 is filled.

In this way, since the drain pump 502 is started after the drain pan 108 is filled with the condensed water before the drain pan 108 is filled with the connection hose 504 and then accumulated in the drain pan 108 to a certain extent or more, the amount of air sucked into the drain pump 502 can be controlled to the minimum. It should be noted that the drain pump 502 is activated when the drain pan 108 accumulates a large amount of condensed water, and this can be realized by providing a detection means in the drain pan 108. Since sanitary problems such as bacterial growth occur if the drain pan 108 contains the condensed water for a long time, it is necessary to minimize the time for the condensed water to flow into the drain pan 108, and it is necessary to stop the operation of the drain pump 502 while keeping the water in the lower end 505 ″ of the connection hose 504 in order to minimize the amount of air sucked into the drain pump 502.

Preferably, inside the connection hose 504, the condensed water is preferably retained until the position indicated by the arrow a in fig. 41. The position indicated by arrow a is the lowest level of condensed water in the interior of the connecting hose 504. The highest water level in the connection hose 504 is the upper end position of the connection portion 505'.

Fig. 42 is a structural diagram of an air management device according to an embodiment of the present invention, fig. 43 is a flowchart illustrating a control method of an air management device according to an embodiment of the present invention, fig. 44 is a flowchart illustrating a control method of an air management device according to another embodiment of the present invention, and fig. 45 is a flowchart illustrating a control method of an air management device according to yet another embodiment of the present invention.

First, a method of controlling the air management device in order to discharge the heat-exchanged air forward in the air management device of the present embodiment will be described with reference to fig. 42 and 43.

According to the air management device of the embodiment of the present invention, the input portion 17 for inputting a user operation is provided on the front surface of the housing 10 forming the appearance of the air management device. The user can input and set the operation of the air management device by operating the input 17.

Here, the user may directly touch the input unit 17 to input the user operation, or may input the user operation by performing wireless communication with an external device.

If the control part 600 determines that a valid user operation is input through the input part 17, the operation for discharging air of the air management device is started to be controlled (S101: input user operation step).

The control portion 600 drives a fan motor (not shown) if a user operation of discharging air for the air management device is received through the input portion 17. Such a fan motor may rotationally drive the fan 130, 130', 130 ". The driving fans 130, 130 ', 130 "are connected to the corresponding fan motors, respectively, and driving force is provided to the driving fans 130, 130', 130" by the driving of the fan motors (S103: driving fan motor step).

Further, a heat exchanger 104 for air heat exchange is disposed inside the casing 10, and an air guide portion 120 is provided in front of the heat exchanger 104. The driving fans 130, 130', 130 ″ are disposed at the wind guide part 120. When the fan motor is driven, the driving fans 130, 130', 130 ″ provided in the wind guide part 120 are rotated (S105: driving fan operation step).

If the driving fans 130, 130 ', 130 ″ are operated, air is sucked from the outside through the suction port 11'. The suction port 11' is provided in the floor 11 of the housing 10 and is disposed at a position separated by a predetermined height from the floor surface of the indoor living space in which the housing 10 is installed.

Since the driving fans 130, 130 ', 130 ″ are rotated, air is sucked through the suction port 11' from the outside and flows into the air flowing space 20 (S107: air sucking step).

The heat exchanger 104 disposed inside the case 10 exchanges heat if air flows into the air flowing space 20 through the suction port 11'. For this purpose, the control unit 600 drives the heat exchanger 206 to perform heat exchange.

Specifically, the air passing through the suction port 11' flows through an air flow path 102 formed in the air flowing space 20. The heat exchanger 104 is provided in the air flow path 102, and the heat exchanger 104 exchanges heat with the air flowing through the air flow path 102 (S109: heat exchange step).

During the above process, the driving fans 130, 130', 130 ″ are operated all the time. Accordingly, the air heat-exchanged in the heat exchanger 104 is transferred to the plurality of discharge ports 15 '-1, 15' -2, 15 '-3 provided in the front plate 15 of the casing 10 by the rotation of the driving fans 130, 130', 130 ″.

In one embodiment, the first, second and third discharge ports 15 ' -1, 15 ' -2 and 15 ' -3 are formed in the front plate 15 side by side in the left and right direction. The discharge ports 15 ' -1, 15 ' -2, 15 ' -3 serve to communicate the air flow space 20 of the housing 10 with the living room space (S111: step of supplying air to the discharge ports).

In the figure, three discharge ports 15 ' -1, 15 ' -2, and 15 ' -3 are provided as an example, but the present invention is not limited thereto, and the number may be two or more.

Next, the control part 600 opens the respective blades 141, 142, and 143 provided at the discharge ports 15 '-1, 15' -2, and 15 '-3 in order to discharge the heat-exchanged air to the outside through the discharge ports 15' -1, 15 '-2, and 15' -3.

In the present embodiment, the blades 141, 142, and 143 are provided at positions corresponding to the three driving fans 130, 130 ', and 130 ″, i.e., the first, second, and third discharge ports 15' -1, 15 '-2, and 15' -3, respectively. These blades 141, 142, and 143 are driven by driving motors 141 ', 142', and 143 'separately provided to open and close the discharge ports 15' -1, 15 '-2, and 15' -3, respectively, thereby setting the direction of the discharged air.

Since the blades 141, 142, and 143 determine the opening and closing of the discharge ports 15 '-1, 15' -2, and 15 '-3, the air supplied to the discharge ports 15' -1, 15 '-2, and 15' -3 can be discharged to the outside only when the blades 141, 142, and 143 are opened (S113: opening blade step).

As described above, the heat-exchanged air can be supplied to the additional discharge unit 200 through the branch flow path 129. The branch flow path 129 is a flow path through which air in the first fan space 124 and the third fan space 124' can flow, and can be a path through which heat-exchanged air is transferred to the additional discharge unit 200. The branch flow channel 129 is open to both side surfaces of the air guide part 120, and communicates with the first space 22 and the second space 24.

The additional discharge part 200 is provided at both sides of the top surface of the case 10. The additional discharge unit 200 may transfer the heat-exchanged air to a wider area by lifting the ejection pipe 234 from the upper portion of the casing 10.

In order to discharge the air heat-exchanged inside to the front of the housing 10 through the plurality of discharge ports 15 ' -1, 15 ' -2, and 15 ' -3, the controller 600 opens the blades 141, 142, and 143 and closes the damper 206 as described above. This is to prevent the heat-exchanged air from being supplied to the additional discharge unit 200 through the branch flow path 129 by closing the damper 206.

This is because, when the air is discharged to the front of the casing 10, the heat-exchanged air is not supplied to the additional discharge portion 200 but is supplied only to the front discharge ports 15 ' -1, 15 ' -2, 15 ' -3 (S115: a damper closing step).

In this way, in a state where the vanes 141, 142, 143 are open and the damper 206 is closed, the air heat-exchanged inside is discharged forward through the plurality of discharge ports 15 ' -1, 15 ' -2, 15 ' -3 provided in the front plate 15 of the housing 10 (S117: step of discharging air).

By these control processes, the air management device can discharge the heat-exchanged air forward. At this time, the angles of the vanes 141, 142, 143 can be adjusted. That is, the control unit 600 may adjust the opening degree of the blades 141, 142, and 143 by adjusting the current supplied to the driving motors 141 ', 142 ', and 143 '.

A control method of the air management device for discharging the heat-exchanged air through the additional discharge portion in the air management device according to the embodiment of the present invention will be described with reference to fig. 42 and 44.

In the air management device according to the embodiment of the present invention, the user may input the operation of the user through the input portion 17. If the control unit 600 determines that the input through the input unit 17 is a user operation for discharging air through the additional discharge unit 200, the operation for discharging air through the additional discharge unit 200 in the air management device is started (S201: a step of inputting a user operation).

If a user operation for discharging air is inputted through the input part 17, the control part 600 drives the respective fan motors (not shown) in order to activate the driving fans 130, 130', 130 ″. The driving fans 130, 130 ', 130 "are respectively connected to corresponding fan motors, and driving force can be provided to the driving fans 130, 130', 130" as the fan motors are driven (S203: driving fan motor step).

Thus, as the fan motor is driven, the driving fan 130, 130', 130 ″ connected to the fan motor 132 is operated. That is, the driving fans 130, 130', 130 ″ rotate. Specifically, a heat exchanger 104 for air heat exchange is disposed inside the casing 10, and an air guide portion 120 is provided in front of the heat exchanger 104. The driving fans 130, 130', 130 ″ are disposed at the wind guide part 120. When the fan motor is driven, the driving fans 130, 130', 130 ″ provided in the air guide part 120 start to rotate (S205: driving fan operation step).

When the driving fans 130, 130 ', 130 ″ are operated, air is sucked from the outside through the suction ports 11'. The suction port 11' is provided at the bottom plate 11 of the housing 10 and is disposed at a position having a certain height from the floor of the indoor residential space where the housing 10 is installed.

As the driving fans 130, 130 ', 130 ″ rotate, air is sucked from the outside through the suction ports 11' and flows into the internal air flowing space 20 (S207: air suction step).

The heat exchanger 104 provided inside the case 10 performs heat exchange if air is sucked into the air flowing space 20 through the suction port 11'. For this purpose, the control unit 600 controls the heat exchanger 206 to perform heat exchange (S209: heat exchange step).

The vanes 141, 142, and 143 provided at the discharge ports 15 '-1, 15' -2, and 15 '-3 are closed when the air is discharged to the outside through the additional discharge part 200, instead of the discharge ports 15' -1, 15 '-2, and 15' -3 provided at the front plate 15 of the housing 10. This is to prevent the air from being discharged from the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 by closing the vanes 141, 142, 143 (S211: vane closing step).

In this way, the control unit 600 closes the vanes 141, 142, and 143 and opens the damper 206 to supply air to the additional discharge unit 200 through the branch flow path 129 in this order (S213: an open damper step).

Thus, the vanes 141, 142, and 143 are closed, the damper 206 is opened, and the air heat-exchanged inside is supplied to the branch flow passage 129 (S215: air supply step to branch flow passage).

Then, the air supplied to the branch flow path 129 is supplied to the additional discharge unit 200 through the branch flow path 129 (S217: air supply step to additional discharge unit).

Thus, the air heat-exchanged inside is discharged to the outside through the additional discharge part 200 provided at the top surface side of the case 10 (S219: air discharge step)

A control procedure for controlling the operation of the additional discharge unit according to still another embodiment of the present invention will be described with reference to fig. 42 and 45.

The user can input the operation of raising and lowering and rotating the additional discharge unit 200 through the input unit 17. If the control unit 600 determines that the input through the input unit 17 is a user operation for discharging air through the additional discharge unit 200, the air management device may start controlling the air discharge through the additional discharge unit 200 (S301: input user operation step).

If a user operation for operating the additional discharge unit 200 is input, the control unit 600 drives the elevation motor 230 in order to raise the additional discharge unit 200 toward the upper portion of the housing 10 (S303: drive elevation motor step).

The additional discharge unit 200 is driven by the elevating motor 230 to be raised and raised toward the upper portion of the casing 10 (S305: additional discharge unit raising step).

If the additional discharge unit 200 is raised toward the upper portion of the housing 10, the control unit 600 drives the eject driving fan 224 for pressurizing the air discharged from the additional discharge unit 200. The ejection driving fan 224 is a device that pressurizes air in the communication flow path 218 to blow the air farther. That is, the air transferred to the branch flow path 219 is pressurized and transferred to the additional discharge unit 200 so that the air is further transferred (S307: the step of driving the pop-up driving fan).

As described above, the air heat-exchanged in the heat exchanger 104 and supplied through the branch flow path 129 is discharged from the ejection outlet 242 by the driving of the ejection driving fan 224 (S309: air discharging step).

The additional discharge unit 200 may be rotated by a predetermined angle. The user can input an operation for rotating the additional ejection unit 200 through the input unit 17. If the control unit 600 determines that the user operation for rotating the additional discharge unit 200 is input through the input unit 17, the operation for controlling the rotation of the additional discharge unit 200 is started in the air management device (S311: input user operation step).

When a user operation for rotating the additional discharge unit 200 is input, the control unit 600 may drive the rotary motor 226 providing a rotational force to the additional discharge unit 200 (S313: drive rotary motor step).

Thus, the additional discharge unit 200 is rotated by driving the rotary motor 226. The air heat-exchanged in the heat exchanger 104 may be discharged to the outside through the additional discharge unit 200 while the additional discharge unit 200 is rotated (S315: rotating additional discharge unit step).

Fig. 46 is a flowchart showing a control method of an air management device according to another embodiment of the present invention, and fig. 47 is a flowchart showing a control method of an air management device according to another embodiment of the present invention.

Referring to fig. 42 and 46, the input portion 17 for inputting a user operation in the air management device according to the embodiment of the present invention is formed on a front plate of the housing 10 constituting an external appearance of the air management device. The user can input and set the operation of the air management device by operating the input portion 17.

Here, the user may directly touch the input unit 17 to input the user operation, or may input the user operation by performing wireless communication with an external device.

If the control unit 600 determines that the user operation input through the input unit 17 is valid, it starts to control the humidification operation of the air management device (S401: input user operation step).

When the user's operation for humidification is input through the input unit 17, the control unit 600 drives the elevating motor 230 to raise the additional discharge unit 200 toward the upper portion of the case 10 in order to discharge the humidified air to the outside through the additional discharge unit 200.

In detail, the elevation motor 230 is provided in the elevation motor housing part 222 of the elevation housing 214. An elevation drive gear 232 that meshes with the elevation rack portion 212 is provided on an output shaft of the elevation motor 230. The lifting drive gear 232 is engaged with the lifting rack portion 212, and moves up and down along the lifting rack portion 212, and accordingly, the lifting housing 214 moves up and down. The ejector pipe 234 is also moved up and down in accordance with the movement of the lift case 214 (S403: additional ejector raising step).

The controller 600 drives the fan motors (not shown) to operate the driving fans 130, 130 ', and 130 ″ in order to supply indoor air into the interior through the suction port 11'. The respective fan motors are connected to the driving fans 130, 130 ', 130 ", respectively, and provide driving force to the driving fans 130, 130', 130", as the respective fan motors are driven.

Thus, as the fan motors are driven, the driving fans 130, 130', 130 ″ connected to the respective fan motors are operated. That is, the fans 130, 130', 130 ″ are driven to rotate. Specifically, the heat exchanger 104 for exchanging heat with air is disposed inside the casing 10, and the air guide portion 120 is provided in front of the heat exchanger 104. The driving fans 130, 130', and 130 ″ are disposed in the air guide part 120. Thus, the driving fans 130, 130', 130 ″ provided in the air guide part 120 are rotated by the driving force transmitted from the fan motor (S405: driving fan operation step).

When the driving fans 130, 130 ', 130 ″ are driven, air is sucked from the outside into the inside of the case 10 through the suction ports 11'. The suction port 11' is provided at the bottom plate 11 of the housing 10 and is disposed at a position having a certain height from the floor of the indoor living space where the housing 10 is installed. As the driving fans 130, 130 ', 130 ″ rotate, air is sucked in through the suction port 11' from the outside and flows into the internal air flowing space 20 (S407: air suction step).

When air is sucked from the outside through the suction port 11', the control unit 600 opens the damper 206 provided at the inlet of the branch flow path 129 in order to supply air to the additional discharge unit 200 through the branch flow path 129.

Thus, as the damper 206 is opened, the air inside is supplied to the branch flow passage 129 (S409: air supply step to the branch flow passage).

The air supplied to the branch flow path 129 is pressurized by the fan in the inflow fan section 403, and flows to the steam generator 407 through the air transfer pipe 405. The humidification pump 417 supplies water from the water tank 419 to the steam generator 407 under the control of the controller 600, and heats water transferred from the water tank 419 in the steam generator 407 to generate steam. The steam thus generated is mixed with the air transferred through the air transfer pipe 405 (S411: a humidified air generating step).

The water tank 419 is mounted to the water tank mount 415. The water tank mount 415 tilts the water tank 419. When the proximity sensor 470 detects a user, the control unit 600 tilts the tank mount 415 to extend the upper end of the tank 419 to the outside in the frame space 203. This is to allow the water tank 419 to easily enter and exit the frame space 203.

The humidified air thus generated is supplied to the additional discharge unit 200. Specifically, the humidified air is transferred to the ejection pipe 234 through the first discharge pipe 409 or the second discharge pipe 411 (S413: a humidified air supply step to an additional discharge unit).

The humidified air transferred to the additional discharge unit 200 is discharged to the outside through the additional discharge unit 200. Specifically, the humidified air is discharged to the outside through the ejection tube 234 formed in the additional discharge unit 200. In this case, when the humidified air needs to be discharged through only one of the ejection tubes 234, only the corresponding discharge tubes 409 and 411 are opened.

For example, when the humidified air is discharged through the ejection tube 234 on the left side of the casing 10, the first discharge tube 409 is opened, and the air flows into the connection flow path 205 of the connection tube 204. At this time, it is preferable that the damper 206 closes the branch flow path 219 (S415: discharge humidified air step).

Thereafter, when a user operation for rotating the additional discharge unit 200 is selectively input, the control unit 600 starts controlling the rotation of the additional discharge unit 200 (S417: input of the user operation).

In response to a user' S operation of the additional discharge unit 200, the control unit 600 starts the operation of the rotation motor 226 to rotate the additional discharge unit 200 (S419: a step of rotating the additional discharge unit).

Thereby, the additional discharge unit 200 ascends and rotates to discharge the humidified air to the outside, and uniformly supplies the humidified air in a desired direction.

Next, a control method of simultaneously performing air temperature setting and humidification in an air management device according to another embodiment of the present invention will be described with reference to fig. 42 and 47.

The user inputs the operation of air temperature setting and humidification to the air management device through the input portion 17 formed on the front surface of the housing 10 of the air management device. In this case, the user may input an operation by directly touching the input unit 17 or by performing wireless communication with an external device.

If the control unit 600 determines that the user operation input through the input unit 17 is valid, it starts controlling the humidification operation of the air management device (S501: input user operation step).

When a user operation for air temperature setting and humidification is input through the input portion 17, the control portion 600 drives a fan motor (not shown) in order to start driving the fans 130, 130', 130 ″. The operation of the driving fans 130, 130', 130 ″ is performed to draw indoor air into the interior of the case 10.

The fan motors are connected to the plurality of driving fans 130, 130 ', 130 ", respectively, and provide driving force to the driving fans 130, 130', 130" according to the driving of the respective fan motors. Thus, as the respective fan motors are driven, the respective driving fans 130, 130', 130 ″ connected to the respective fan motors 132 are operated. That is, the driving fans 130, 130', 130 ″ rotate.

Specifically, the heat exchanger 104 for exchanging heat with air is disposed inside the casing 10, and an air guide portion 120 is provided in front of the heat exchanger 104. The air guide part 120 is provided with driving fans 130, 130', 130 ″. The driving fans 130, 130', 130 ″ provided in the air guide part 120 are rotated by the driving force transmitted from the fan motor (S503: driving fan operation step).

When the driving fans 130, 130 ', 130 ″ are operated, air is sucked from the outside to the inside of the case 10 through the suction port 11'. The suction port 11' is provided at the bottom plate 11 of the housing 10 and is disposed at a position having a certain height from the floor of the indoor living space in which the housing 10 is installed.

As the driving fans 130, 130 ', 130 ″ rotate, air is sucked from the outside through the suction ports 11' and flows into the air flowing space 20 inside (S505: air suction step).

When the air flows into the air flowing space 20 through the suction port 11', the heat exchanger 104 provided inside the case 10 performs heat exchange. For this, the control unit 600 drives the heat exchanger 104 to perform heat exchange.

Specifically, the air passing through the suction port 11' flows through the air flow path 102 formed in the air flow space 20. The heat exchanger 104 is provided in the air flow path 102, and the heat exchanger 104 exchanges heat with the air flowing through the air flow path 102 (S507: heat exchange step).

In the above process, the driving fans 130, 130', 130 ″ are continuously operated. Accordingly, the air heat-exchanged in the heat exchanger 104 is transferred to the plurality of discharge ports 15 '-1, 15' -2, 15 '-3 provided in the front plate 15 of the casing 10 by the rotation of the driving fans 130, 130', 130 ″.

In one embodiment, the first, second and third discharge ports 15 ' -1, 15 ' -2 and 15 ' -3 are formed in the front plate 15 in parallel on the left and right sides. The discharge ports 15 ' -1, 15 ' -2, 15 ' -3 serve to communicate the air flow space 20 of the housing 10 with the living room space (S509: air supply to discharge ports step).

In the figure, three discharge ports 15 ' -1, 15 ' -2, 15 ' -3 are illustrated as an example, but the present invention is not limited thereto, and the number thereof may be two or more. The controller 600 opens the blades 141, 142, and 143 provided at the discharge ports 15 '-1, 15' -2, and 15 '-3 to discharge the heat-exchanged air to the outside through the discharge ports 15' -1, 15 '-2, and 15' -3.

In the present embodiment, the blades 141, 142, and 143 are provided at positions corresponding to the three driving fans 130, 130 ', and 130 ″, i.e., the first, second, and third discharge ports 15' -1, 15 '-2, and 15' -3, respectively. The blades 141, 142, and 143 are driven by driving motors 141 ', 142', and 143 'separately provided, thereby opening and closing the discharge ports 15' -1, 15 '-2, and 15' -3 to set the direction of the discharged air.

Since the opening and closing of the discharge ports 15 '-1, 15' -2, 15 '-3 are determined by the blades 141, 142, 143, only when the blades 141, 142, 143 are opened, the air supplied to the discharge ports 15' -1, 15 '-2, 15' -3 can be discharged to the outside (S511: blade opening step).

As described above, the heat-exchanged air can be supplied to the additional discharge unit 200 through the branch flow path 129. The branch flow path 129 is a flow path through which air flows from the first fan space 124 and the third fan space 124', and serves as a flow path through which the heat-exchanged air is transferred to the additional discharge unit 200. The branch flow channels 129 are open to both side surfaces of the air guide part 120, and communicate with the first space 22 and the second space 24. In order to supply air to the branch flow path 129, the damper 206 is opened.

The additional discharge part 200 is provided at both sides of the top surface of the case 10. The additional discharge unit 200 may be configured to raise the ejection pipe 234 from the top surface of the casing 10 and to send the heat-exchanged air to a wider area.

The control part 600 opens the vanes 141, 142, 143 and the damper 206 to discharge the air heat-exchanged inside to the front of the case 10 through the discharge ports 15 ' -1, 15 ' -2, 15 ' -3 and discharge the humidified air through the additional discharge part 200. This is because the heat-exchanged air is supplied to the additional discharge unit 200 through the branch flow path 129 by opening the damper 206.

This is to discharge the heat-exchanged air to the front of the case 10 and discharge the humidified air through the additional discharge unit 200. Thus, the heat-exchanged air is supplied to the branch flow path 129 by opening the damper 206 (S513: air supply step to branch flow path).

The air supplied to the branch flow path 129 is pressurized by the fan in the inflow fan section 403, and then is transferred to the steam generator 407 through the air transfer pipe 405. The water transferred from the water tank 419 is heated at the steam generator 407 to generate steam, and the steam thus generated is mixed with the air transferred through the air transfer pipe 405 (S515: generating humidified air step).

In order to discharge the humidified air to the outside through the additional discharge unit 200, the elevating motor 230 is driven to raise the additional discharge unit 200 toward the top surface of the housing 10. Specifically, the lift motor 230 is provided in the lift motor housing 222 of the lift box 214. An elevation drive gear 232 is provided on an output shaft of the elevation motor 230, and engages with the elevation rack portion 212. The lifting drive gear 232 is engaged with the lifting rack portion 212 to move up and down along the lifting rack portion 212, and accordingly, the lifting housing 214 moves up and down. The ejector pipe 234 is lifted and lowered together with the lifting and lowering of the lifting and lowering case 214 (S517: additional ejector lifting step).

Thus, the generated humidified air is supplied to the additional discharge unit 200. Specifically, the humidified air is delivered to the pop-up pipe 234 through the first discharge pipe 409 or the second discharge pipe 411 (S519: supplying humidified air to the additional discharge portion step).

The humidified air transferred to the additional discharge unit 200 is discharged to the outside through the additional discharge unit 200. Specifically, the humidified air is discharged to the outside through the ejection tube 234 formed in the additional discharge unit 200. At this time, when the humidified air is discharged through only one of the discharge pipes 234, only the corresponding discharge pipes 409 and 411 are opened.

For example, when the humidified air is discharged through the ejection tube 234 on the left side of the casing 10, the first discharge tube 409 is opened to allow the air to flow into the connection flow path 205 of the connection tube 204. At this time, it is preferable that the damper 206 closes the branch flow path 219 (S521: a humidified air discharging step).

Thereafter, if a user operation for rotating the additional discharge unit 200 is selectively input, the control unit 600 starts controlling the rotation of the additional discharge unit 200 (S523: input of the user operation).

The control unit 600 starts the rotation motor 226 to rotate the additional discharge unit 200 according to an operation for rotating the additional discharge unit 200 input by a user.

Thus, the additional discharger 200 discharges the humidified air to the outside while rotating in a state of being lifted up to the upper portion of the casing 10, thereby uniformly discharging the humidified air in an ideal direction (S525: a step of rotating the additional discharger).

As described above, in the embodiment of the present invention, the additional discharge unit 200 is rotated after being lifted up, and discharges the humidified air to the outside.

The scope of the invention should be construed in accordance with the claims, and all technical ideas within the equivalent scope should be construed to fall within the scope of the invention.

In the illustrated embodiment, there are three discharge ports 15 ' -1, 15 ' -2, and 15 ' -3, but the number of discharge ports is not limited to at least two. For example, when there are two discharge ports, the vanes are opened to the front of the casing 10 to transfer air, and the air is also transferred to the additional discharge portion 200, so that the air can be transferred in an ideal direction. That is, the damper 206 is opened while the vanes are also opened to allow air to flow. In addition, the two discharge ports can be controlled individually by closing the damper 206 to deliver air in a desired direction in front of the housing 10.

When there are four or more discharge ports, for example, the driving fan corresponding to the discharge ports located at both ends is operated to transfer air to the additional discharge portion 200, or the air may be transferred to the front of the housing through the discharge ports by opening the blades. The remaining exhaust ports are shown as the second exhaust ports 15' -2 of the illustrated embodiment for delivering air to the front of the housing 10.

In the illustrated embodiment, the branch flow path 129 communicates with a vertical pipe 208 through a connecting pipe 204. However, the branch flow path 129 and the vertical pipe 208 may be directly connected to each other through the damper 206. In the illustrated embodiment, the vertical pipe 208 is positioned relatively apart from the air flowing space 20 toward the end of the housing 10 in the first space frame 202, and thus the connection pipe 204 is required, but the connection pipe 204 may not be required if the vertical pipe 208 is close to the air flowing space 20.

In addition, the first discharge pipe 409 may be directly connected to the vertical pipe 208 without the connection pipe 204.

In the illustrated embodiment, the first moving plate 16 is automatically opened and closed, but the present invention is not limited thereto, and the user may open and close the first moving plate 16 himself or herself, and the tilting table 449 of the tank attachment 415 may be tilted by the proximity sensor 470 or a separate button.

In addition, in order to raise and lower the ejection pipe 214, a lift driving source 224 is provided in the ejection pipe 214, and a lift rack portion 212 is formed in the vertical flow path 210. However, the elevating drive source 224 may be provided at the uppermost end of the vertical flow path 210, and the elevating rack portion 212 may be formed in the vertical direction on the rear surface of the eject pipe 214.

In the illustrated embodiment, three filters 320, 330, 340 are used, but not limited thereto, and at least two or more filters may be used. In addition, three passage regions 302 are formed in the filter frame 301, but two or more may be formed.

In the illustrated embodiment, in order to facilitate the filter frame 301 to be drawn in and out of the housing 10, the rail assembly 350 is used, but the rail assembly 350 is not necessarily used. The filter frame 301 may be configured to be drawn in and out without the rail assembly 350.

In the illustrated embodiment, the elastic brush 375 is used to prevent the suction force from leaking from the dust collector suction port 373, but various leakage blocking members such as an elastic sealing member may be provided instead of the elastic brush 375 to achieve the same object.
