Description

DESCRIPTION

Ceiling fan and control method for the same

[Technical field]

The present invention relates to a ceiling fan.

[Background Technique]

A flow-generating device refers to a device that drives a fan to generate airflow and provide the generated airflow to a user. This type of flow generating device is often referred to as a fan.

The flow generation device can be variously classified according to the flow generation form, the function, the installation form and the like. A device, which is installed on the surface of a wall or a ceiling, of the flow generating device for generating an air flow is called a ceiling fan.

The ceiling fan has been widely used in houses or shopping malls because the ceiling fan can provide economic advantages to the user since the ceiling fan requires less energy than an air conditioner or a general fan.

Generally, the ceiling fan includes a drive motor to provide power and a plurality of blades connected to a drive motor shaft.

The ceiling fan can circulate the air in a room using the wind generated by the rotation of the blades. Consequently, the ceiling fan can lower or raise the indoor temperature.

The ceiling fan differs from a conventional flow generating device that is arranged on the ground surface to be erected to concentrate the air flow in a local space. In detail, the ceiling fan can be placed on the ceiling higher than the user to force airflow in a larger volume.

Therefore, the ceiling fan can circulate the air in the whole room to achieve even temperature distribution in the room, thus providing a comfortable feeling for the user.

However, a conventional ceiling fan has the following problems.

First of all, a conventional fan has a problem that a rotating blade unit is integrally coupled with components. In other words, when a user views the ceiling fan, the lower components of the ceiling fan rotate along with the blade unit. Consequently, the conventional ceiling fan may not provide visual information through the lower components.

Second, since the conventional ceiling fan has a greater number of components that rotate with the blade, more rotational power can be provided from a motor to increase vibration and noise.

Third, in the conventional ceiling fan, a driver chip for controlling the motor is installed in the motor assembly. In other words, in order to install the driver chip to control the motor, the installation space of an additional PCB must be secured inside the motor assembly. Consequently, in order to prevent various wires connecting the PCB with the motor from interfering with the rotation of the motor, the structure is complicated.

Fourth, when a plurality of electronic components within a plurality of electronic components are installed within the conventional ceiling fan, it is difficult to meet the electromagnetic interference (EMI) or electrostatic discharge (ESD) standards.

Fifth, the conventional ceiling fan has no drive to prevent pest access. Sixth, the conventional fan may not interact with other air conditioning products installed in various ways in the room.

Information on a prior art related to this document is as follows.

The scope of the invention is defined by the appended claims.

FIGURE 1 is a perspective view illustrating a ceiling fan according to one embodiment of the present disclosure.

Referring to Figure 1, according to one embodiment of the present invention, a ceiling fan 1 includes all the features of claim 1.

The main blade 100 extends in a radial direction around the axis of rotation.

In addition, the shafts 10 and 20 are intended to extend along the central axis of the covers 13, 15, 30 and 90. Consequently, the axis of rotation can be understood as the central axis of the ceiling fan 1. Hereinafter, the axis of rotation may be referred to as the "central axis".

Furthermore, an inner surface of the main blade 100 can be defined as a lateral side facing the central axis. Accordingly, an outer surface of the main blade 100 can be defined as a lateral side that is opposite to the inner surface and faces in the radial direction.

In other words, the main blade 100 extends a predetermined length in the radial direction perpendicular to the central axis.

The upper surface of the main blade 100 forms a negative pressure surface and the lower surface of the main blade 100 forms a positive pressure surface.

Meanwhile, the front and rear portions can be defined based on the forward rotation that the blades 100 and 200 of the ceiling fan 1 rotate clockwise. For example, the main blade 100 has a leading edge formed on a front facing surface and a trailing edge formed on a rear facing rear surface, when viewed based on the direction of rotation.

Bearing 43 can be positioned above the central part of stator 41. Bearing 43 can be formed to encircle shaft 20 of the motor.

The bearing 43 can support the shaft 20 of the motor. The motor shaft 20 can be understood as a central axis of rotation of the motor assembly 40. However, the motor shaft 20 is fixedly coupled to the ceiling, so the motor shaft 20 is static.

In addition, the jumpers 55 can enlarge the installation space so that a plurality of electronic components are installed under the shaft 20 of the motor. Consequently, the plurality of electronic components can be kept in a fixed position without rotating, regardless of the rotation of the ceiling fan 1.

The jumper 55 can be inserted into a jumper hole 71 provided in the jumper box 70. Furthermore, the bridge 55 inserted into the bridge hole 71 can be coupled by the coupling member. Accordingly, the bridge support 50 and the bridge box 70 can be coupled with each other to be fixed firmly.

In addition, the rotation unit includes the housing cover 30, the main blade 100 and the secondary blade 200. In the ceiling fan 1 according to an embodiment of the present disclosure, since the number of components (rotation unit) that rotate is smaller in comparison with the conventional ceiling fan, the discharged air volume can be increased when the ceiling fan 1 provides the same amount of rotational power as the conventional ceiling fan, and the rotational power can be smaller when the same volume of air is provided, thus reducing energy consumption.

In addition, the fixing unit and the rotation unit may be formed to provide the feeling of unity in the outward appearance structure seen by a user. For example, the housing cover 30 may extend downward to be formed so that the diameter of the upper end of the housing cover 30 is equal to the diameter of the lower end of the lower cover 15. The display cover 90 may be formed to have a lower end diameter that is equal to the central diameter defining the central hole 105 in the decorative cover 190 or the lower end diameter of the housing cover 30.

In addition, the fixing unit and the rotation unit may have a space 107 between them to prevent friction between them even though the fixing unit and the rotation unit provide the feeling of unity in outward appearance.

In detail, the bottom end and the inner surface of the bottom cover 15 may be spaced from the housing cover 30 by a predetermined distance as described above. The lower end of the display cover 90 may be separated from the lower ends of the decorative cover 190 and the housing cover 30 by forming a recess 107 outwardly. Accordingly, a connection part between the rotation unit that rotates and the fixing unit that has a statically fixed position can be minimized, thus reducing friction noise.

Furthermore, the components constituting the rotation unit can be coupled together so as to form a space between them.

In detail, the main blade 100 can be attached to the decorative cover 190 to form a predetermined space together with the decorative cover 190.

In detail, the main blade 100 can be coupled to the blade connector 35 of the housing cover 30 to form a space together with the blade connector 35 . Accordingly, the frictional noise caused by the mating state between the components in the rotating slewing unit can be further reduced.

Furthermore, the fixing unit can be stably fixed by the shaft 10 attached to the ceiling or to the wall surface. In detail, on the shaft 10, the motor shaft 20 can stably fix the bridge bracket 50 attached to the bottom of the motor shaft 20 and the electronic components 60, 70, 80, 85, 88 and 90 attached to the bridge support 50.

The bridge hole 71 may be positioned on the top surface of the bridge box 70 so that the bridge 55 provided in the bridge holder 50 is inserted into the bridge hole. For example, the bridge holes 71 can be formed at positions corresponding to a plurality of bridges 55.

In other words, a plurality of bridge holes 71 can be formed at the upper end of the bridge box 70 to be separated from each other by a predetermined distance in the circumferential direction. Furthermore, the bridge hole 71 can be formed by drilling the top surface of the bridge box 70 downward.

The plurality of jumpers 55 are inserted into the plurality of jumper holes 71, respectively, and each jumper 55 and the respective jumper hole 71 are coupled together by a separate coupling member for fixing the jumper 55 and the jumper hole 71 thus coupling the bridge support 50 to the bridge box 70.

A plurality of electronic components installed in the internal space formed by the display cover 90 and the jumper box 70 can be electrically connected with other electronic components positioned in the control assembly 60 through the hole 73 of the harness 73.

The insertion slot 74 can be formed in the lateral side of the bridge box 70. For example, the insertion slot 74 may include a slot recessed inward from a lower end of the lateral side of the bridge box 70 . In addition, the insertion slot 74 may include a coupling hole into which the coupling element is inserted and engaged.

The insertion slot 74 can guide the engagement of the display cover 90. In other words, the display cover 90 can be attached through the insertion slot 74.

Meanwhile, the display cover 90 can be attached to a lower part of the bridge case 70. For example, the lower end of the bridge box 70 can be seated within the display cover 90. In addition, the display cover 90 may include a cover extension portion 91 that extends perpendicularly upward from the lower end thereof.

The cover extension portion 91 may extend along the outer circumference of the display cover 90, that is, in a circumferential direction of the display cover 90.

For example, the coupling guide 92 may extend upward in a bent and extended "L" shape.

Since the mating guide 92 is mounted in the insert slot 74, the mating guide 92 can be formed to correspond to the insert slot 74. In other words, the plurality of mating guides 92 can be formed to correspond to positions where the insertion slots 74 are formed. Furthermore, the coupling guide 92 may be shaped corresponding to the shape of the insertion slot 74 so that the coupling guide 92 is inserted and mounted in the insertion slot 74.

The coupling guide 92 may have a coupling hole formed therein. Furthermore, the coupling hole may be positioned to correspond with the coupling hole formed in the insertion slot 74. Therefore, the display cover 90 and the jumper box 70 can be attached as a separate coupling member to the coupling holes formed in the coupling guide 92 and the insertion slot 74 . Electronic components 60, 70, 80, 85, 88 and 90 can be formed on multiple floors. In detail, the electronic unit may include a two-stage electronic unit. The electronic unit in a lower deck can be formed in the internal space protected by the display cover 90 and the jumper box 70. Furthermore, the electronic unit in an upper floor can be formed in the internal space protected by the coupling of the upper control box 61 and the lower control box 65.

Consequently, the problem, such as the EMI described above, caused by the installed electronic components can be easily solved.

Furthermore, according to the multi-stage electronic unit, a control component can be arranged in an electronic unit relatively close to the position of any component that requires electrical connection. Accordingly, since the cable connection is shorter and easier, the ratio of the cable occupying the space can be relatively reduced and the space can be made clean.

In addition, since a plurality of harness holes are formed, the user can easily perform the wire connection work.

The bridge support 50 positioned below the motor assembly 40 can form an internal space 57, in which the control assembly 60 is positioned, while being coupled to the bridge box 70 so as to form the multi-stage electronic unit. .

Consequently, the installation space in which the fixing unit is installed can be enlarged and the space for the static component, that is, the installation space without rotation, can be guaranteed.

In other words, the bridge bracket 50 and the bridge box 70 serve as a bridge to stably fix and link the space in which a plurality of electronic components are installed.

As described above, according to the conventional ceiling fan, the rotating blade and the upper and lower components are integrally coupled with each other. Consequently, the lower components within the user's field of view (viewing range) rotate along with the blade. Therefore, according to the conventional ceiling fan, it is difficult to provide visual information to the user through the bottom component.

In addition, in the conventional ceiling fan, since the number of components rotating together is relatively increased, vibration and noise are relatively increased, and the motor must provide a higher rotation power.

In addition, in the conventional ceiling fan, since a lower part thereof is integrally attached to the rotating part, the components arranged in the lower part may not be fixed stably. Consequently, in the conventional ceiling fan, the load has to be restrained for safety. In addition, the space of the conventional ceiling fan is insufficient to install electronic components that provide various convenience functions. Also, the conventional ceiling fan is restricted in terms of position due to rotation.

However, the ceiling fan includes a fixing unit stably fixed by maintaining the coupling force from the ceiling and a rotating unit separate from the fixing unit and including only the essential components for rotating the blades 100 and 200.

Accordingly, even if the number of components included in the rotating unit is relatively reduced to provide the rotating power slightly, air can be provided in an equal or greater volume.

Furthermore, the fixing unit is formed toward the central axis. Accordingly, a plurality of electronic components (electronic unit), which are used to provide comfort to a user, or components of the ceiling fan 1 corresponding to the field of vision of the user can be installed in a larger space.

In addition, the ceiling fan 1 can position the plurality of electronic components capable of providing various conveniences to the user at the bottom of the motor assembly 40 and fix the electronic components that are not to rotate.

In other words, since the positions of the plurality of electronic components (electronic unit) are set without the influence of the rotation of the blades 100 and 200, visual information can be provided to the user.

In addition, the plurality of electronic components (electronic unit) can be more stably and fixedly attached to the bottom of the motor assembly 40, so that the range of allowable load values can be increased.

In addition, the user looking at the ceiling from the floor of the room can provide readability and visibility for the operating information of the ceiling fan 1 since the display cover 90 is held in a fixed position without rotating.

In addition, the blade connector 35, the main blade 100 and the secondary blade 200 of the rotary unit housing cover 30 are coupled with each other to form a predetermined gap between them, whereby the noise caused by the friction of the rotating unit can be reduced.

A plurality of bridges 55 may be provided. In other words, the plurality of bridges 55 may extend perpendicularly and downwardly along the outer circumference of the support plate 51. Consequently, the plurality of bridges 55 can form a space in which the control assembly 60 is positioned. The bridge 55 can be inserted into the bridge hole 71 provided in the bridge box 70 .

A plurality of seating guides 93 can be provided. For example, a plurality of seating guides 93 can be arranged at predetermined intervals in the circumferential direction along the inner circumferential surface of the cover extension part 91.

In other words, the plurality of seat guides 93 may be spaced apart from each other in the circumferential direction.

The seating guide 93 can form a seating groove 93a into which the lower end of the bridge box 70 is inserted.

The seating groove 93a can be formed by cutting the upper end of the seating guide 93 downwards. For example, the seating groove 93a can be formed in such a way that a portion of the seating groove 93a, which is in contact with the inner surface of the cover extension portion 91, is tapered downward from the upper end. of the seat guide 93.

The plurality of seating grooves 93a can be provided in a number corresponding to the number of seating guides 93 . In detail, the lower end of the bridge box 70 can be inserted into the seating grooves 93a formed in the upper surfaces of the plurality of seating guides 93 .

Accordingly, the bridge case 70 can be stably seated and fixed inside the display cover 90.

The display cover 90 may further include a feed port 90a which is an opening formed in a base surface. In this case, the base surface can be defined as an inner circumferential surface of the display cover 90 for supporting the extension part 91 of the cover. For ease of explanation, the base surface may be referred to as the lower surface of the display cover.

The feeding port 90a can guide a light emitted from a light-emitting device arranged in the display module 85 so that the light is directed into the interior space. For example, the feed port 90a can be positioned on one side of the display cover 90 even though it is spaced from the center of the display cover 90.

The display cover 90 may further include an outlet 95 which is an opening formed in the center of the display cover 90.

Outlet port 95 may include a plurality of regularly arranged ports. For example, a plurality of outlet holes 95 having seven hexagonal shapes can be arranged in the center of the display cover 90 to form a hexagonal shape as a whole. Furthermore, at least one of seven hexagonal shapes may include seven open outlet holes 95 in the hexagonal shape.

A partial configuration of the anti-insect module 80 can be seated on the upper side of the outlet hole 95. The display cover 90 may further include a speaker coupling portion 900 for guiding the coupling of the speaker 83.

The speaker 83 converts an electrical signal received from the anti-insect module 81 into an acoustic signal, thus discharging the ultrasound into the interior space through the outlet port 95.

Accordingly, an ultrasound can be emitted to stimulate the nerve of pests, so that access of pests to a peripheral part of the ceiling fan 1 can be prevented.

Accordingly, ultrasonic avoiding pests can be prevented from accessing the ceiling fan 1, so that the management of the ceiling fan 1 is improved.

The loudspeaker 83 may have a fitting part 83a formed to protrude in the radial direction from the outer end part.

The fitting part 83a can be inserted into the fitting slot 96a when the speaker 83 is seated in a speaker coupling part 96. Therefore, the fitting portion 83a and the fitting groove 96a can be shaped for mutual engagement with each other.

In other words, the center of the display cover 90 can be placed on the line of the central axis of the ceiling fan 1. An airflow stagnation region in which the airflow is relatively slower than in other indoor space may be formed vertically below the display cover 90 .

The ultrasonic output of the anti-insect module 80 can be influenced by the air flow.

For example, when the speaker 83 is provided in another position instead of the center of the lower end of the ceiling fan 1, the ultrasonic output of the speaker 83 may be more affected by the airflow generated by the rotation of the blades 100 and 200.

In other words, ultrasonics may not be evenly distributed to the surrounding area of the ceiling fan 1 due to air pressure difference, air flow rate, air flow direction and the like.

Therefore, in order to effectively eliminate pests by ultrasonic output from the anti-insect module 80, it is preferred that the ultrasonics be emitted to the area where the fluctuation of airflow is relatively low.

As a result, the position where the speaker 83 is installed. That is, the optimal position of the outlet hole 95, from which the ultrasound is emitted, can be the center of the display cover 90 which forms the center of the lower end of the 1 ceiling fan. Accordingly, since the emitted ultrasound is relatively less influenced by the air flow, it is possible to more effectively prevent the access of pests around the ceiling fan 1.

The display module 85 can be placed on the speaker 83 mounted on the speaker coupling part 900 .

The display cover 90 may further include a display module docking device 96 and a display module guide 97 for guiding the docking of the display module 85 .

The display module guide 97 can be formed in such a way that the corner portions of the display module 85 are fixed to contact the display module guide 97 . For example, display module guide 97 may extend perpendicularly upward from the base surface of display cover 90 to support the top and side ends of display module 85.

The display module coupling device 96 may be formed of a material that allows elastic deformation. For example, the display module docking device 96 may be formed to extend upwardly in the shape of a hook.

The display module coupling device 96 can be elastically deformed outward when the display module 85 is inserted downwards along the display module guide 97 .

When the display module 85 is seated in the seated position and insertion is complete, the display module engaging device 96 may spring back to press and fix the display module 85.

Light guide 94 may extend upwardly from the base surface (or bottom surface) of display cover 90 to form a hole having a rectangular cross section. For example, light guide 94 may have a vertically open hexahedral shape.

In other words, the light guide 94 can form the light hole 94a in the vertical direction.

In addition, the light guide 94 may extend from the base surface of the display cover 90 so that the sectional area of the light guide 94 tapers upward from the base surface. For example, the light guide 94 may be in the shape of a truncated quadrangular pyramid.

The light guide 94 can be positioned vertically downward to correspond to the light emitting device installed in the display module 85.

In other words, the light-emitting device can be mounted on the display module 85 such that the light-emitting device corresponds to an upper part of the light hole 94a. Therefore, the lights provided by each of the plurality of light-emitting devices can be directed into the interior space along the respective light guides 94 so as to prevent the lights from interfering or influencing each other. Accordingly, lights having different intensities and colors, which are provided from a plurality of light-emitting devices, can be provided into the interior space without being mixed together by the light guide 94 . Therefore, the ceiling fan 1 has the advantage that it can provide clear visual information according to the functions.

The plurality of light guides 94 can have different shapes. For example, some of the plurality of light guides 94 may be extended to have a rectangular section of wider area, and may be arranged to be further apart from each other in one direction. For example, others of the plurality of light guides 94 may be extended to have a narrower area rectangular section, and may be arranged to be less spaced apart in one direction.

Accordingly, the plurality of light guides 94 can guide lights having different intensities or colors. Meanwhile, the light-emitting device may be installed by a separate module other than the display module 85. For example, the display cover 90 may have another light emitting diode (LED) to correspond to an outer opening 801 (see FIGURE 16) formed in a circle along the outer circumference of the lower surface of the cover 90. display.

The display cover 90 may further include a communication module guide 99a for guiding the engagement of the communication module 88, a communication module lock portion 99b, and a communication module engagement device 98 .

The communication module guide 99a can be formed in a side space of the display cover 90 to prevent interference between the display module 85 and the communication module 88.

Furthermore, the guides 99a of the communication module can be provided in a pair. For example, the communication module guides 99a may extend upwardly from mutually spaced positions on the base surface of the display cover 90 while forming a pair.

Communication module guide 99a may have an upper end that is bent so that the communication module lateral end 88 is seated. The guide 99a of the communication module may be in the shape of an 'L'. Therefore, the communication module 88 can be seated in the guide pair 99a of the communication module.

The communication module guide 99a can fix one end of the communication module 88. The communication module lock part 99b can fix the other end of the communication module 88.

The communication module lock portion 99b may be formed to protrude upwardly from the base surface of the display cover 90 and may extend a predetermined length in the circumferential direction.

A pair of locking protrusions can be formed at the upper ends of the communication module locking part 99b to press the communication module 88 from above.

Therefore, the communication module 88 may have a side portion seated in the communication module guide 99a and an opposite side seated and inserted into the communication module lock portion 99b. In this case, the communication module coupling device 98 may be coupled to the communication module 88. In detail, a pair of communication module coupling devices 98 can be provided in a pair for fixing an upper end and a lower end of the communication module 88, respectively. Also, the communication module docking device 98 may extend upwardly from the base surface of the display cover 90 to be hook-shaped. The display module coupling device 98 may be formed of a material that allows elastic deformation. Therefore, when the communication module 88 is inserted so that the communication module 88 is mounted on the communication module guide 99a and the communication module locking part 99b, the communication module coupling device 98 it elastically deforms to guide the communication module 88 so that the communication module 88 can be seated, and then can be recovered to fix and engage the communication module 88.

For example, the control unit 300 may receive and process information, such as a user-set temperature, a real-time indoor temperature, or a real-time detected amount of dust from another cooperating air conditioning product through the module. 88 communication. Furthermore, the control unit 300 may reversely provide the above information to another air conditioning product through the communication module 88.

The control unit 300 may perform a control operation in relation to the engine assembly 40 to control the RPM of the engine.

Furthermore, the control unit 300 may perform a control operation in connection with the display module 85 to control the brightness or color of the illumination.

FIGURE 18 is a flowchart illustrating a method of controlling a ceiling fan that does not form part of the claimed invention.

Referring to FIGURE 18, the ceiling fan 1 can be operated by interacting with a plurality of air conditioning products installed in the indoor space.

First, the ceiling fan 1 can be turned on depending on the input signal from the user. In other words, the ceiling fan 1 1 can be turned on (S10).

Furthermore, the ceiling fan 1 can determine the connection status of the communication module 88 (S20). For example, the control unit 300 may perform a control operation to reset the communication module 88 and correctly operate the communication module 88 according to a control command.

Furthermore, the ceiling fan 1 can make a communication connection with a plurality of air conditioning products installed in the indoor space (S30).

In this case, the plurality of air conditioning products may include a heating/cooling appliance having a communication device connected with the communication module 88. For example, the heating/cooling appliance may include a heater, a fan, and an air conditioner.

The ceiling fan 1 can be synchronized with another air conditioning product through the communication connection. For example, the ceiling fan 1 may make the communication connection with another air conditioning product, which is running first, to receive the control sequence of the connected air conditioning product.

Furthermore, the ceiling fan 1 can determine whether to enter an intelligent circulation mode (S40).

In detail, when the communication connection with a plurality of air conditioning products is achieved, the control unit 300 can determine whether to enter the intelligent circulation mode, depending on the input signal of a user or the input state. established. For example, when the user enters the intelligent mode using the input device, the control unit 300 may determine that the intelligent circulation mode is allowed to be entered.

On the contrary, the control unit 300 may perform a control operation that allows the ceiling fan 1 to enter a normal mode, when the entry into the intelligent circulation mode is not allowed (S48).

The intelligent circulation mode can be defined as a mode to recognize the mutual operation state with the interconnected or synchronized air conditioning product through the communication module 88 and to manage the total state of the indoor space air.

When the ceiling fan 1 enters the intelligent circulation mode, the ceiling fan 1 can determine the operating states of the plurality of air conditioning products cooperating with the ceiling fan 1 (S45).

In detail, the control unit 300 may receive the information on the operating state of the cooperating air conditioning product (cooling/heating appliance) to determine the operation of the ceiling fan 1. For example, the control unit 300 can determine the home appliance whose power is turned off among the interconnected air conditioning products (air conditioning home appliance).

In this case, the control unit 300 may perform a control operation to perform the normal operation when all the cooperating air conditioning products are turned off (S48).

In addition, when some of the cooperating air conditioning products are turned off, the control unit 300 can perform a control operation to operate integrally with the remaining product except for the product in the off state.

Furthermore, the ceiling fan 1 can receive the indoor environment information detected by the cooperating air conditioning product.

For example, the control unit 300 may receive an indoor temperature detected by the air conditioner mounted on the wall surface of the room, and may receive an amount of indoor dust and comfort information from the air purifier installed in the room. ground surface.

In this case, the control unit 300 can compare the information from the detection module 310 installed in the vicinity of the ceiling to determine the red zone of the interior space.

In addition, the control unit 300 can change the operation configuration of the ceiling fan 1 and a plurality of air conditioning products cooperating with the ceiling fan 1 to improve the airflow circulation in a certain position as the red zone, while performing the operation based on the intelligent circulation mode.

In addition, when the user setting values of the cooperating air conditioning products are different from each other, the ceiling fan 1 makes the user setting values identical to the user setting information input to the ceiling fan 1 to fully perform a control operation.

Furthermore, the ceiling fan 1 can perform an operation based on the intelligent circulation mode (S50). In the operation based on the intelligent circulation mode, the heating or cooling operation of the ceiling fan 1 can be determined to determine the directions of rotation of the blades 100 and 200 corresponding to the relevant operations (S60 and S70).

For example, when the operation is executed in the intelligent circulation mode, the ceiling fan 1 may receive the operation mode of the cooperating air conditioning product.

Furthermore, when the cooperating air conditioning product performs the cooling operation, the ceiling fan 1 determines a mode as the cooling mode (S60). When the cooperating air conditioning product performs the heating operation, the ceiling fan 1 determines the mode as a heating mode (S70).

When the ceiling fan 1 determines the mode as the cooling (operation) mode, the ceiling fan 1 can control the blades 100 and 200 to perform forward rotation. Forward rotation can be defined as the rotation in which the blades 100 and 200 rotate in a clockwise direction. The forward rotation of the ceiling fan 1 can maximize the cooling effect of the cooling operation (S65).

For example, when the cooperating air conditioning product performs the cooling (operation) mode, the control unit 300 can recognize that it is necessary to provide cooling to the indoor space, and can control the engine assembly 40 to perform the advance operation. based on a pre-established basic RPM.

When the ceiling fan 1 determines the mode as the heating (operation) mode, the ceiling fan 1 can control the blades 100 and 200 to perform reverse rotation. Reverse rotation can be defined as a rotation in which the blades 100 and 200 rotate counterclockwise. The reverse rotation of the ceiling fan 1 can maximize the cooling effect of the cooling operation (S75).

For example, when the cooperating air conditioning product performs the heating (operation) mode, the control unit 300 may recognize that it is necessary to provide heating to the indoor space, and may control the motor assembly 40 to perform the reverse operation in based on a preset base RPM.

In other words, the operation of the ceiling fan 1 can be performed so that the ceiling fan 1 follows the modes of operation of the plurality of air conditioning products.

Furthermore, the ceiling fan 1 can determine the difference between the user setting information and the detected indoor information (S80).

In more detail, the control unit 300 can determine the differential value between the indoor temperature and the user-set temperature with respect to each section of the indoor space by combining the detection information of the detection module 310 of the ceiling fan 1 and the information detection of the plurality of cooperating air conditioning products.

For example, the control unit 300 can determine the detection information of the detection module 310 such as the air condition of the interior space of the ceiling, and can determine the detection information received from an air purifier installed on the floor surface. as the state of the air in an interior space close to the surface of the ground. In addition, the control unit 300 can determine the detection information received by the inner side wall-mounted air conditioner as the air condition of the inner side space.

In addition, the control unit 300 can calculate the difference between the user setting value and the detection value with respect to each section of the indoor space and can store the calculated value.

The ceiling fan 1 can control complementary operation with a plurality of cooperating air conditioning products using the storage information for each space section. inside. In other words, the ceiling fan 1 can change the RPM of the motor according to the difference between the temperature set by the user and the indoor temperature (S85).

For example, when the cooling operation is performed and when the differential value between the user-set temperature and the indoor temperature is large, the ceiling fan 1 may increase the RPM to perform a control operation so that the circulation of indoor air accelerates.

Furthermore, when the difference between the user setting value and the detection value is large in a specific section of the indoor space, the ceiling fan 1 can control the air conditioning product closest to the corresponding section to improve the intensity. cooking or heating, and you can increase the RPM of the ceiling fan 1 to maximize the cooling effect.

Thereafter, the ceiling fan 1 can determine whether the detection value in the indoor space satisfies the user's setting value (S90).

For example, the ceiling fan 1 can determine whether the indoor temperature meets the temperature set by the user.

In addition, the ceiling fan 1 can end the intelligent circulation mode when the detection value in the indoor space satisfies the setting value of the user.

FIGURE 19 is a view illustrating the direction of rotation and the direction of airflow according to the cooling mode or the heating mode of the ceiling fan 1.

When ceiling fan 1 determines that cooling is required in the indoor space, ceiling fan 1 performs forward rotation R, and when ceiling fan 1 determines that heating is required, ceiling fan 1 performs reverse rotation R'. Accordingly, the cooking or heating effect can be maximized.

Referring to FIGURE 19, when the ceiling fan 1 performs forward clockwise rotation R, the airflow direction may be upward flow toward the ceiling fan 1 and may be an upward flow downward moving away from ceiling fan 1.

In other words, when the ceiling fan 1 performs forward rotation, the air near the ceiling fan 1 is pushed downward by the blades 100 and 200, and the air near the inner wall, which is pushed relatively far away from the fan 1 ceiling, rises by the air flow introduced from the bottom of the interior to form the negative pressure.

Accordingly, when a cooling mode is performed and the ceiling fan 1 performs forward rotation, the hot air in the lower part of the interior can be circulated to the outside to maximize the cooling effect.

Meanwhile, when a heating mode is performed, since the indoor temperature has been lowered substantially, the hot air discharged through the air conditioning product may naturally form an upward airflow due to the temperature difference.

Accordingly, the ceiling fan 1 can perform the reverse rotation R' in the heating mode. According to the reverse rotation R', the air flow is forced so that the air in the vicinity of the ceiling fan 1 rises upward by the rotation of the blades 100 and 200. Consequently, a flow of air down H on inner side wall.

Consequently, the ceiling fan 1 can prevent hot air, which is discharged from other air conditioning product, from concentrating in the vicinity of the ceiling due to the cold indoor temperature and can forcefully circulate the air in the rooms. proximities of the ceiling towards the lower part of the interior space. Accordingly, the heating effect can be maximized.

FIGURE 20 is a schematic view illustrating comprehensive indoor air management when the ceiling fan interacts with a plurality of air conditioning products according to one embodiment of the present disclosure.

Referring to FIGURE 20, there may be several air conditioning products installed in the room. In addition, the installation positions of the air conditioning products may be different from each other.

The air conditioning product may include an air conditioner, an air purifier, a dehumidifier, a humidifier, a general fan, and a heating device.

For example, the ceiling fan 1 can be installed on the ceiling of a room. In addition, other air conditioning products can be installed at mutually different positions in the room. In detail, a D1 wall-mounted air conditioner can be installed on one wall surface, and a D2 air purifier or humidifier can be installed on an opposite side of the room.

Meanwhile, as described above, the ceiling fan 1 can be operated by interacting with the air conditioner D1 and the air purifier D2.

In this case, the ceiling fan 1, the air conditioner D1 and the air purifier D2 D2 can share the indoor air environment set by the user. In other words, various air conditioning products installed in the indoor space can interact with each other and can operate with the same value set by the user.

That is, all the air conditioning products installed in the indoor space can interact with each other to uniformly and fully control the indoor air conditioning environments.

Accordingly, since the air conditioning products work on the ceiling, wall surface and floor of the room, the circulation of indoor air can be quickly realized and the cooling or heating effect can be improved.

In other words, depending on the cooling mode or heating mode, the indoor temperature can be quickly reached to the set temperature and the air purification time is shortened. Accordingly, the user M can feel the comfortable feeling of the indoor air environment.

In addition, an amount of dust, temperature and the like are detected at the position where each air conditioning product is installed, and the air conditioning product works to reach the setting value of the user, so that the red zone may resolved and the uniform indoor air environment can be fully achieved.
