The plurality of decor covers 190 may be coupled to each other by being dependent on the plurality of main blades 100.

The subblade 200 may be located in the blade hole 103. The subblade 200 may extend to have a predetermined curvature.

In addition, the subblade 200 may be disposed to have an inclination angle different from that of the main blade 100. For example, the subblade 200 may have an extension surface for guiding air to have an angle of attack different from that of the main blade 100.

The subblades 200 may be provided in plural numbers so as to correspond to the number of the main blades 100.

The subblade 200 may include a sub coupling hole 230 for coupling with the main blade 100 and the decor cover 190.

When the subblade 200 is mounted on the main blade 100, the sub coupling hole 230 may be positioned to correspond to the main coupling hole 115. Accordingly, the fastening member inserted into the sub coupling hole 230 may pass through the decor fastening hole 193 and the main coupling hole 115 together.

The sub coupling hole 230 may be formed at one end of the subblade 200. The sub coupling hole 230 may be formed to be seated on an upper side of the main coupling hole 115.

In summary, the sub coupling holes 230 may be positioned to be aligned side by side in the vertical direction together with the main coupling holes 115 and the deco coupling holes 193 when the main coupling holes 100 are coupled to the main blades 100.

The subblade 200 may include a sub connector 250 for guiding the coupling between the plurality of main blades 100.

The subblade 200 may be seated on the main blade 100 so as to correspond to the blade connector 35 in the vertical direction.

The subconnector 250 may be formed at the other end of the subblade 200. For example, the sub connector 250 may extend in a shape corresponding to the blade connector 35.

The sub-connector 250 may be seated at a position where the two main blades 100 are coupled to each other. For example, the sub connector 250 may be seated at a position where the first main blade 100a and the second main blade 100b are coupled to each other.

The control assembly 60, the bridge case 70, the display cover 90, and the plurality of modules 80, 82, and 88 may be defined as electrical components. That is, the electric component may be understood as the configuration of the ceiling fan 1 in which a plurality of electric components are installed.

The electrical component may be located in the inner space of the housing cover 30 and may be coupled to the lower side of the motor shaft 20. Therefore, the electric parts may be stably fixed by the coupling force transmitted from the indoor ceiling.

Meanwhile, the ceiling fan 1 is provided such that only the upper cover 13, the low cover 15, the housing cover 30, the display cover 90, the main blade 100 and the sub blade 200 are exposed to the outside. Therefore, since the appearance is simple and unified, it can provide aesthetics to the user.

Figure 4 is a block diagram showing the configuration of a ceiling fan according to an embodiment of the present invention.

Referring to FIG. 4, the ceiling fan 1 may further include a controller 300 that controls each component.

In addition, the controller 300 may be provided in the electronic device. As an example. The controller 300 may include the main PCB 600 described above.

The controller 300 may process data transmitted and received by the communication module 88. The controller 300 may communicate with an air conditioning product installed in the same room using the communication module 88.

The communication module 88 may be connected to an external server or a router provided separately.

A plurality of air conditioning products may be connected to the server or router to communicate. Here, the plurality of air conditioning products may include an air cleaner, a humidifier, a dehumidifier, an air conditioner, a fan, a circulator, and the like.

In addition, the air conditioner may include a ceiling type, stand type, wall-mounted air conditioner.

In addition, the plurality of air conditioning products may be located in a room where the ceiling fan 1 is installed.

Thus, the ceiling fan 1 and the plurality of air conditioning products connected to the server or router can communicate with each other. Thus, the ceiling fan 1 and the air conditioning product can be interlocked.

That is, the ceiling fan 1 may form a network with the plurality of air conditioning products.

The controller 300 may receive information such as a user set temperature, a real time indoor temperature, a real time dust detection amount, and the like from the plurality of air conditioning products.

Therefore, even if the user set temperature is input to only one of the products, the ceiling fan 1 and the plurality of air conditioning products can be linked to set a common user set temperature.

Of course, the controller 300 may provide the information detected by the ceiling fan 1 to the air conditioning product.

The controller 300 may be connected to the motor assembly 40 to control the rotation speed (RPM) of the motor and perform the control.

In addition, the controller 300 may be connected to the display module 85 to control brightness, color, and the like of lighting.

In addition, the control unit 300 may be connected to the anti-bug module 80 to generate an ultrasonic wave to avoid pests to control to emit to the outside of the ceiling fan (1).

The ceiling fan 1 may further include a memory unit 330 for storing data, a sensing module 310 for sensing an environment of an indoor space, and an input / output module 320 for receiving a user command.

The controller 300 may read data stored in the memory 330, and may store processed information.

The sensing module 310 may include a temperature sensor for detecting an indoor temperature, a dust sensor for detecting an indoor dust amount, a humidity sensor for detecting an indoor humidity, and the like.

Of course, the information detectable by the sensing module 310 may be replaced by information detected from the interlocked air conditioning product.

In addition, the controller 300 may process the information detected by the sensing module 310. For example, the controller 300 may calculate a difference between an indoor temperature and a user set temperature by the sensing module 310. The controller 300 may manipulate the motor assembly 40 to vary the number of rotations based on the calculated temperature.

The input / output module 320 may include a portable display device, a smart phone, a remote control, and the like.

In addition, the input / output module 320 may be connected to the above-described server or router. Accordingly, the user may integrally control the ceiling fan 1 and a plurality of air conditioning products linked to the ceiling fan 1 by using the input / output module 320.

The input / output module 320 may provide an input screen for inputting a user's control command. In detail, the user may select a menu displayed on the input screen and input a control command to the ceiling fan 1. Here, the control command may be applied to a plurality of air-conditioning products interlocked.

In addition, the input / output module 320 may provide a menu for selecting a user so as to interwork the ceiling fan 1 with a plurality of air conditioning products located nearby.

In addition, the input / output module 320 may display indoor environment information such as temperature, humidity, and dust provided from the controller 300 and provide the same to the user.

Meanwhile, the controller 300 may receive a user's input command by the input / output module 320. The controller 300 may process the input command.

For example, the controller 300 may process an input command such as an operating time, a user set temperature, a set air volume, a sleep reservation, and a display presence or the like of the ceiling fan 1 received from the input / output module 320.

5 is a flowchart illustrating a method of controlling a ceiling fan according to a first embodiment of the present invention.

The ceiling fan 1 may operate in conjunction with a plurality of air conditioning products installed in the indoor space.

Referring to FIG. 5, the ceiling fan 1 may be powered on according to an input signal of a user. That is, the ceiling fan 1 may be in a power-on state (S1).

In addition, the ceiling fan 1 may check the connection state of the communication module 88. (S2)

For example, the controller 300 may reset the communication module 88 to control to be performed correctly according to a control command.

In addition, the ceiling fan 1 may perform a communication connection for interworking with a plurality of air conditioning products.

The ceiling fan 1 may be synchronized with the air-conditioning product interlocked through a communication connection.

For example, the ceiling fan 1 may perform a communication connection from another air-conditioning product that has been operated first, and receive a control sequence of the linked air-conditioning product.

The ceiling fan 1 may determine whether to enter the smart circulation mode. (S4)

In detail, when a communication connection is made with a plurality of air conditioning products, the controller 300 may determine whether to enter the smart circulation mode according to a user input signal or a set input state.

For example, when the user inputs the smart circular mode using the input / output device 320, the controller 300 may determine that the smart circular mode is entered.

On the contrary, if it is determined that the control unit 300 does not enter the smart circulation mode, the control unit 300 may control to enter the normal operation mode of the ceiling fan 1 (S4-2).

The smart circulation mode may be defined as a mode capable of real-time recognizing the operating conditions of the air conditioning products and the mutually coordinated or synchronized with each other by the communication module 88 and managing the overall air condition of the room. Can be.

When entering the smart circulation mode, the ceiling fan 1 may determine the operating state of the linked air-conditioning product. (S4-1)

In detail, the control unit 300 may receive the information on the operating state of the air-conditioning product linked to determine the operation of the ceiling fan (1).

For example, the controller 300 may determine the home appliance of which power is turned off among the linked air-conditioning products. The controller 300 may control to perform normal operation according to a user's selection if the power of all the interlocked air conditioning products is turned off. (S4-2)

In addition, if the power of some of the interlocked air-conditioning products is off, the controller 300 may perform the smart circulation mode except for the off-state products according to the user's selection.

In addition, the ceiling fan 1 may be provided with indoor environment information sensed by the linked air-conditioning product.

For example, the control unit 300 may receive the sensed room temperature from the air conditioner installed on the indoor side wall. Of course, it will be apparent that the air conditioner can be detected not only in the stand type and the wall type but also in the ceiling type air conditioner. In addition, the control unit 300 may receive the indoor dust amount or comfort level information from the air cleaner installed on the ground.

In this case, the controller 300 may determine blind spots of the indoor space by comparing the information with the sensing module 310 installed near the ceiling.

The controller 300 may control to enhance the air flow circulation to the position determined as the blind spot while executing the operation according to the smart circulation mode. In this case, the controller 300 may control to change the operation setting of the interlocked air conditioning product.

In addition, when the user setting values for the linked air-conditioning products are different, the ceiling fan 1 may be integrated and controlled by matching the user setting information input to the ceiling fan 1.

In addition, the ceiling fan 1 may execute the operation according to the smart circulation mode (S5).

In the operation according to the smart circulation mode, it is possible to determine whether the ceiling fan (1) cooling or heating operation, and determine the rotation direction of the blade (100,200) corresponding to each operation (S6, S7).

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

The ceiling fan 1 may be determined as a cooling mode when the linked air conditioning product is operated in a cooling mode (S6), and may be determined as a heating mode when the linked air conditioning product is driven in a heating mode (S7). .

In the cooling mode, the ceiling fan 1 may control the blades 100 and 200 to perform forward rotation. The forward rotation may be defined as the blades 100 and 200 rotate clockwise. Forward rotation of the ceiling fan 1 can maximize the cooling effect of the cooling operation. (S6-1)

For example, when the linked air-conditioning product is operated in a cooling mode, the controller 300 recognizes that cooling is required in an indoor space, and the motor assembly 40 is configured according to a preset basic rotation speed (RPM). It can be controlled to perform forward operation.

On the other hand, when operating in the heating mode, the ceiling fan 1 may control the blades (100, 200) to perform the reverse rotation. The reverse rotation may be defined as the blades 100 and 200 rotate counterclockwise. Reverse rotation of the ceiling fan (1) can maximize the heating effect of the heating operation. (S7-1)

For example, when the linked air-conditioning product performs heating, the controller 300 recognizes that it is necessary to provide heating to the indoor space, and operates the motor assembly 40 according to a preset basic rotation speed (RPM). Can be controlled to perform

That is, the ceiling fan 1 may be operated to follow the operation mode of the interlocked air conditioning product.

In addition, the ceiling fan 1 may determine a difference between the user setting information and the detected indoor environment information.

In detail, the control unit 300 synthesizes the sensing information of the air-conditioning product linked with the sensing information of the sensing module 310 of the ceiling fan 1, and the difference between the current room temperature and the user setting temperature for each section of the indoor space. You can check the value.

For example, the control unit 300 may determine the sensing information of the sensing module 310 as the air condition of the indoor ceiling space, and the sensing information received from the air cleaner installed on the ground as the air state of the indoor space near the ground. The detection information received from the air conditioner installed on the indoor sidewall may be determined as the air state of the indoor side space.

The controller 300 may obtain and store a difference between a user setting value and a detection value for each compartment of the indoor space.

The ceiling fan 1 may perform a complementary operation together with the interlocked air conditioning product by using the storage information for each partitioned indoor space.

The ceiling fan 1 may change the motor rotation speed (RPM) according to the difference between the user set temperature and the current room temperature. (S8-1)

For example, when the cooling operation is performed, the ceiling fan 1 may increase the motor speed RPM to increase the circulation of indoor air if the difference between the user set temperature and the current room temperature is large. .

In addition, the ceiling fan 1 may be controlled to enhance the cooling or heating intensity of the air-conditioning product closest to the corresponding compartment space, if the difference between the user setting value and the detection value in a specific compartment space is large, At the same time, by increasing the number of revolutions (RPM) of the ceiling fan (1) can maximize the cooling effect.

Thereafter, the ceiling fan 1 may determine whether the indoor sensing value satisfies a user setting value (S9).

For example, the ceiling fan 1 may determine whether the room temperature satisfies a user set temperature.

The ceiling fan 1 may end the smart circulation mode when the indoor sensing value satisfies the user setting value.

6 is a flowchart illustrating a control method of a ceiling fan according to a second embodiment of the present invention, and FIGS. 7A to 7C illustrate a user inputting interlocking operation using an input / output module according to a second embodiment of the present invention. Illustrates a process for example.

Referring to FIG. 6, the ceiling fan 1 may be powered on. For example, the ceiling fan 1 may be started by receiving a user's power ON input. That is, the ceiling fan 1 may be in a power-on state. (S10)

When the ceiling fan 1 is turned on, the ceiling fan 1 may check the connection state of the communication module 88.

For example, the controller 300 may reset the communication module 88. Accordingly, the controller 300 may prepare the communication module 88 to correctly perform communication according to a user's input command. That is, the ceiling fan 1 may perform an initialization process.

In addition, the ceiling fan 1 may be interlocked operation input by the user (S20).

The interlocking operation input step (S20) may be understood as a step of determining whether or not a communication connection is performed so as to collectively or integrally control a plurality of air conditioning products with one input / output module 320.

On the other hand, if the interlocking operation is not input, the ceiling fan 1 may operate alone.

As described above, the plurality of air-conditioning products may include air-conditioning and home appliances that communicate with the communication module 88. For example, the air-conditioning home appliances may include a heater, a fan, an air conditioner, and the like. The air conditioner may include a ceiling type, a stand type, and a wall type air conditioner.

Referring to FIG. 7A, an air volume intensity, a display, a sleep reservation, a repeat reservation, and a smart circulation mode menu for controlling the ceiling fan 1 may be displayed on the screen of the input / output module 320.

In addition, a user may select the ceiling fan 1 and a plurality of air conditioning products to interwork by touching an icon corresponding to the smart circulation mode. That is, the interlocking operation of the ceiling fan 1 may be input.

In addition, the control unit 300 may control to switch the output screen of the input / output module 320 to the communication connection screen by receiving the user's interlocking operation input. In addition, the controller 300 may detect and arrange an air conditioning product that can be interlocked with the ceiling fan 1.

In addition, the ceiling fan 1 may perform (or complete) a communication connection with an air conditioning product connected to a server (or a router) (S30).

For example, referring to FIG. 7B, the communication connection screen may be output on the screen of the input / output module 320. The communication connection screen may display a list of air conditioning products that can be interlocked with the ceiling fan 1.

The user may select a product to be connected to the ceiling fan 1 by touching the screen of the input / output module 320.

The air-conditioning product displayed on the communication connection screen is a product connected to the server (or router) and is a product that can be electrically connected to the ceiling fan 1 and enjoys a common space with the ceiling fan 1. It can be understood as an air conditioning product.

For example, the user arranges the air cleaner in a room where the ceiling fan 1 is installed, and registers the air cleaner to the server through the input / output module 320 to interlock the ceiling fan 1 and the air cleaner. Can be.

As another example, the user may register the living room air conditioner provided in the living room in which the ceiling fan 1 is installed in a server to interwork the ceiling fan 1 with the air cleaner and the living room air conditioner.

The living room air conditioner may be provided as an air conditioner of any one type of ceiling type, stand type, and wall type.

The controller 300 may perform a communication connection with the selected air conditioning product.

On the other hand, the ceiling fan 1 may be synchronized with the selected air-conditioning product by performing a communication connection. For example, the ceiling fan 1 may perform a communication connection with the living room air conditioner, which has been operated first, to receive the control sequence of the living room air conditioner.

According to this, the control unit 300 may acquire the indoor environment information and the preset user setting condition from the air conditioning product which is operating first.

After the user selects the linkable air conditioning product, the ceiling fan 1 may complete the communication connection of the selected air conditioning product.

The air conditioner product of which the communication connection is completed may be referred to as an “interlocked air conditioner product”.

The ceiling fan 1 may determine the execution of the interlocking operation with the interlocked air conditioning product. That is, the execution of the smart circulation mode may be determined.

Here, the smart circulation mode, in real time to recognize the operating conditions of each other and the air conditioning products interlocked or synchronized with each other by the communication module 88 can be integrated to manage the overall air condition of the room (management) Can be defined as a mode.

For example, referring to FIG. 7C, on the output screen of the input / output module 320, an air conditioning product, that is, a living room air conditioner, in which a communication connection is completed and an interlocking operation is prepared.

At this time, the output screen is an icon for stopping the interlocking with the air-conditioning product prepared for the interlocking operation by completing the communication connection, an icon for changing the air-conditioning product to perform the communication connection, and the interlocking operation with the air conditioning product prepared for the interlocking operation Smart circular mode icon to start the display can be displayed.

In addition, the user may start the interlocking operation of the ceiling fan 1 and the living room air conditioner by touching the smart circulation mode execution icon displayed on the output screen of the input / output module 320.

The controller 300 may determine whether to execute the smart circulation mode according to a user's input or a set input state. For example, when the user inputs the execution of the smart circulation mode, the control unit 300 may start the smart circulation mode to perform the interlocking operation of the ceiling fan 1 and the linked air conditioning product.

On the other hand, if it is determined that the control unit 300 does not enter the smart circulation mode, the control unit 300 may control to the general mode in which the ceiling fan 1 is operated alone.

When the smart circulation mode is executed, the ceiling fan 1 may determine the operating state of the linked air-conditioning product.

In detail, the control unit 300 may receive information on an operating state of an interlocked air conditioning product. The controller 300 may determine the operation of the ceiling fan 1 based on the information received from the linked air-conditioning product.

For example, the controller 300 may determine a product of which power is turned off among the linked air conditioning products. That is, the controller 300 may determine a product that has not been operated before the ceiling fan 1 is turned on.

In this case, the control unit 300 may control to start the operation together with the ceiling fan 1 by transmitting a control command to turn on the power off the product.

On the other hand, the control unit 300 may determine the interlocked air-conditioning product in operation before the power of the ceiling fan 1 is turned on. The controller 300 may be provided with indoor environment information and / or pre-set user setting condition from the air conditioning product in operation.

Here, the indoor environment information may include a current room temperature, a current indoor dust amount, a current indoor cleanness, a current indoor humidity, and the like.

The user setting condition may include temperature, dust amount, cleanliness, humidity, and the like.

The temperature among the user setting conditions may be referred to as “user setting temperature” as a desired temperature set by the user. Similarly, the amount of dust in the user setting condition is called “desired dust amount” and can be displayed numerically. In addition, the cleanliness of the user setting conditions may be named "desired cleanliness", and may be displayed at a gradual level.

For example, the controller 300 may be provided with the current room temperature sensed by the air conditioner installed on the indoor wall. In addition, the controller 300 may be provided with the current indoor dust amount, the current indoor cleanness (or comfort) information from the air cleaner standing on the ground.

In addition, when the user setting condition stored in the linked air-conditioning product and the user setting condition stored in the ceiling fan 1 are different, the controller 300 is inputted to the ceiling fan 1 which is the latest input information. Integrated control can be performed by matching user setting conditions.

In addition, the ceiling fan 1 may detect or determine a difference between a user setting condition and an indoor environment.

In other words, the ceiling fan 1 may calculate a difference between a user setting condition and an indoor environment.

As described above, the indoor setting information for determining the user setting condition and / or the current indoor environment may be provided from an air conditioning product that is determined to be operating in step S50.

The controller 300 may calculate a difference between the user setting condition and the indoor environment by using the user setting condition and / or indoor environment information provided from the linked air conditioning product.

Of course, when there is no air conditioning product in operation, the user setting condition may be directly input by the input / output module 320 of the ceiling fan 1.

The indoor environment information may be provided by a sensor (not shown) provided in the sensing module 310 and / or the interlocked air conditioning product.

The difference between the user setting condition and the indoor environment may be defined according to the linked air conditioning product.

Each factor selected according to the linked air conditioning product may be the same in order to detect a difference between a user setting condition and an indoor environment.

For example, when the linked air conditioning product is an air conditioner, the user setting condition may be defined as a desired temperature input by the user, that is, a user setting temperature. In this case, the indoor environment information for determining the indoor environment may be defined as the current room temperature. Here, the selected factor is temperature.

The air conditioner may include a ceiling type, a stand type, and a wall type air conditioner.

Accordingly, when the ceiling fan 1 and the air conditioner are linked to operate the smart circulation mode, the controller 300 may calculate a difference value between the user set temperature and the current room temperature.

Further, the control unit 300 receives the detected information from the sensing module 310 and the sensing information of the linked air-conditioning product, and calculates a difference between a user set temperature and a current indoor temperature for each compartment of the indoor space. It may be.

In detail, the controller 300 may recognize the information detected by the sensing module 310 as environmental information near the indoor ceiling. In addition, the controller 300 may recognize the information detected from the air cleaner installed on the ground as environmental information near the indoor ground. In addition, the controller 300 may recognize the information detected from the air conditioner installed in the indoor side wall as environmental information near the indoor side wall. Here, it may be assumed that the air cleaner and the air conditioner are each provided with a temperature sensor and are interlocked with the ceiling fan 1.

Therefore, the controller 300 may partition the indoor space based on the ceiling, the ground, and the sidewalls, and calculate and store a difference value between the user set temperature and the detected current indoor temperature for each partitioned space.

As another example, when the linked air-conditioning product is an air purifier, the user setting condition may be defined as the desired dust amount or the desired cleanness. In this case, the indoor environment information for determining the indoor environment may be defined as the current indoor dust amount or the current indoor cleanness.

Accordingly, when the ceiling circulation system 1 and the air cleaner operate in conjunction with the smart circulation mode, the controller 300 may determine the amount of the desired dust amount (or desired cleanness level) and the current indoor dust amount (or current indoor cleanness level). The difference value can be calculated.

On the other hand, when the linked air-conditioning product is an air conditioner and an air purifier, the user setting condition is defined by the user setting temperature and the desired dust amount (or desired cleanliness), and each indoor environment information factor It will be obvious to calculate the difference value.

The ceiling fan 1 may determine whether the difference value ΔT between the user setting condition and the indoor environment satisfies a preset range.

The preset range may be stored in a table in the memory unit 330 in advance.

The preset range may include a first range, a second range, and a third range.

The first range may be defined such that the difference value ΔT has a relatively small value. For example, when the selected factor is a temperature, the first range may be defined as 0 (° C) <difference value ΔT ≤ 2 (° C).

The second range may be defined such that the difference value ΔT is greater than the first range. For example, when the selected factor is a temperature, the second range may be defined as a range where 2 (° C) <difference value ΔT ≤ 5 (° C).

The third range may be defined such that the difference value is larger than the second range. For example, when the selected factor is temperature, the third range may be defined as 5 (° C) <difference value (ΔT).

The number of the preset ranges is not limited to this.

The number of the preset range may correspond to the number of steps divided by the rotation speed RPM of the ceiling fan 1 to be described later.

The ceiling fan 1 may determine the rotation speed based on the detected or determined difference.

In other words, the ceiling fan 1 may determine the rotation speed based on the calculated difference.

For example, when the difference value between the user set temperature and the current room temperature is relatively large, the ceiling fan 1 may increase the rotation speed RPM so that circulation of the indoor air may be faster. Here, the rotation speed can be understood as the rotation speed of the motor described above.

Hereinafter, step S60 will be described in more detail.

The controller 300 may control a motor according to a revolution per minute (RPM) stored in advance in order to provide wind strength step by step.

In one example, the rotation speed (RPM) may be defined as about, medium, steel. The rotation speeds of the weak, middle and rivers may be stored in the memory unit 330 in advance so that the wind intensity may be classified step by step.

In addition, the above-described preset ranges may be matched with the pre-stored RPMs and stored.

In detail, when the difference value DELTA T satisfies the first range, the rotation speed is determined (or matched) to "weak or weak wind", and when the difference value DELTA T satisfies the second range, The rotation speed may be determined as “medium or heavy wind”, and when the difference value ΔT satisfies the third range, the rotation speed may be determined as “strong or strong wind”.

The rotation speed may be increased toward the strong wind from the weak wind.

For example, when the selected factor is a temperature, if the difference value is 2 (° C), the first range is satisfied. Therefore, the controller 300 may control the rotation speed RPM as a medicine corresponding to the first range.

The rotational speed (RPM), which is divided in stages such as weak, medium, and steel, can be understood as indoor airflow desired and expected by the user.

In other words, if the difference value satisfies the third range, it can be understood that the user expects more powerful and direct airflow. Therefore, in this case, the control unit 300 may control the rotation speed RPM.

It can also be understood that if the difference value satisfies the second range, the user expects a direct airflow that is not too strong. Therefore, in this case, the control unit 300 may control the rotation speed RPM.

Also, if the difference value satisfies the first range, the user can be understood as expecting a gentle air flow. Therefore, in this case, the controller 300 may control the rotation speed (RPM) to about.

On the other hand, when the difference value between the user set temperature and the current room temperature is stored for each partitioned space as described above, the ceiling fan 1 may control the rotation speed by using the information stored for each partitioned space.

That is, the ceiling fan 1 may perform a complementary operation for each of the divided spaces together with the interlocked air conditioning products.

For example, when the difference between the user setting temperature and the current room temperature is greater than a predetermined reference value in one partitioned space, the controller 300 may determine the number of rotations of the air-conditioned product disposed in or closest to the partitioned space. It can be controlled to increase the air flow circulating through the partitioned work space. At the same time, the controller 300 may maximize the effect by increasing the rotation speed (RPM) of the ceiling fan (1).

The ceiling fan 1 may determine an operation mode (S70).

The operation mode may include cooling and heating.

The operation mode may be directly input by the user by the input / output module 320. In addition, as described above in step S50, it may be determined by receiving the operation mode information of the linked air-conditioning product.

For example, the controller 300 may determine an operation mode for cooling if the linked air-conditioning product is performing cooling, and determine an operation mode for heating if heating is performed. That is, the ceiling fan 1 may operate to follow the operation mode of the linked air-conditioning product.

Of course, the control unit 300 may automatically determine the cooling mode or the heating mode based on the information detected by the sensing module 310.

On the other hand, the control unit 300 may determine the operation mode to Auto (Auto) when the cooling or heating operation is not provided to the linked air-conditioning product. For example, when the linked air conditioning product is an air purifier, the controller 300 may determine an operation mode as Auto.

The auto mode may be defined as an operation mode that controls the rotation direction of the ceiling fan 1 to be described later according to whether the current room temperature is high (+) or low (-) based on a user set temperature.

For example, in the auto mode, the ceiling fan 1 is rotated forward when the current room temperature is higher than the user set temperature, and the ceiling fan 1 is turned off when the current room temperature is lower than the user set temperature. Can be rotated backwards.

The ceiling fan 1 may determine the rotation direction based on the determined operation mode and the determined rotation speed.

In other words, since the determined number of revolutions corresponds to a set range to which the calculated difference value belongs, the ceiling fan 1 may determine the rotation direction based on the determined operation mode and the calculated difference value.

In detail, when the determined operation mode is the cooling mode, the ceiling fan 1 may perform forward rotation when the determined rotation speed satisfies the steel or the medium.

That is, when the difference value ΔT satisfies the second range or the third range and the operation mode is determined as the cooling mode, the controller 300 may control the blades 100 and 200 to perform the forward rotation. Can be.

The forward rotation may be defined as the blades 100 and 200 rotate clockwise (see FIG. 8).

Here, the forward rotation of the ceiling fan 1 can maximize the indoor cooling effect according to the cooling mode. Detailed description thereof will be described later with reference to FIG. 7.

Meanwhile, when the difference value ΔT satisfies the first range and the driving mode is determined as the cooling mode, the controller 300 may control the blades 100 and 200 to perform reverse rotation.

The reverse rotation may be defined as the blades 100 and 200 rotate counterclockwise (see FIG. 7).

In summary, in the cooling mode, when the calculated difference value ΔT is smaller than a preset reference (eg, the maximum value of the first range), the controller 300 moves the blades 100 and 200 in the reverse direction. It can be controlled to rotate.

On the other hand, if the calculated difference value ΔT is greater than a preset reference, the controller 300 may control the blades 100 and 200 to rotate in the forward direction.

On the other hand, when the rotation speed (RPM) is weak despite the cooling mode, it can be understood that the user expects a gentle cooling air flow as described above.

In order to satisfy this, in the first range in which the difference between the user set temperature and the current room temperature is relatively small, the rotation direction may be determined in a reverse direction rather than in the forward direction to optimize the cooling effect.

On the other hand, when the determined operation mode is the heating mode, the ceiling fan 1 may perform a reverse rotation.

That is, when the operation mode is determined as the heating mode, the controller 300 may control the blades 100 and 200 to rotate in the reverse direction regardless of the rotation speed.

Here, the reverse rotation of the ceiling fan 1 can maximize the heating effect of the heating operation. Detailed description thereof will be described later with reference to FIG. 7.

On the other hand, as described above, when the determined operation mode is the auto mode, the ceiling fan 1 may determine the rotation direction based on the difference between the user set temperature and the current room temperature.

In detail, when the current room temperature is higher than the user set temperature (+), the controller 300 rotates the ceiling fan 1 in a forward direction so that a downdraft is formed at the center thereof, and the current room temperature is the user. When the temperature is lower than the set temperature (−), the ceiling fan 1 may be reversely rotated so that an upward air flow is formed at the center.

In addition, the ceiling fan 1 may perform rotation in the determined rotation speed and the determined rotation direction.

According to this, the ceiling fan 1 and the linked air-conditioning product work together to satisfy common user setting conditions, so that the user setting conditions can be quickly reached. That is, the indoor comfort can be improved more quickly and the redundant energy consumption can be reduced. In addition, the integrated control can improve the control convenience of the user.

Thereafter, the ceiling fan 1 may determine whether the indoor environment satisfies a user setting condition.

In detail, the controller 300 may determine whether the current indoor environment information satisfies a user setting condition after a predetermined time elapses. That is, the controller 300 may update the real-time indoor environment information from at least one of the sensing module 310 and the sensor of the linked air conditioning product.

For example, after a predetermined time elapses, the controller 300 may determine whether the detected current room temperature satisfies a user set temperature.

The ceiling fan 1 may end the smart circulation mode when the indoor environment satisfies a user setting condition.

On the other hand, when the indoor environment does not satisfy the user setting condition, the ceiling fan 1 may change the rotation speed. (S90)

For example, if it is determined in step S85 that the current room temperature is less than the user set temperature, the controller 300 may control the rotation speed to increase to reach the user set temperature more quickly.

That is, the controller 300 may control the rotation speed to increase by one step from 'weak' to 'middle' or 'middle' to 'strong'.

In the following, another embodiment is proposed.

In detail, the detecting of the difference between the user setting condition and the indoor environment (S60) may further include determining a blind spot of the indoor space.

In detail, the controller 300 may determine the blind spot of the indoor space by comparing the sensing information of the sensing module 310 installed in the ceiling fan 1 with the indoor environment information provided from the linked air conditioning product.

Here, the blind spot may be defined as an area in which dust inhalation effect is low, an area in which cold or warm air does not reach, an area in which airflow is stagnated, and the like.

And detecting the difference between the user setting conditions and the indoor environment (S60) may further comprise the step of controlling the ceiling fan (1) and the linked air-conditioning product to eliminate the determined blind spots. have.

For example, the control unit 300 controls to increase the rotational speed of the ceiling fan 1 in order to enhance the air flow circulation of the determined blind spots, and the air volume of the air conditioner and the air purifier of the interlocked air conditioning products It can be controlled to increase the intake amount of.

According to this, the blind spot of the indoor can be minimized and effective indoor air conditioning can be realized.

8 is a view showing an exemplary air flow direction of the room according to the rotation direction of the ceiling fan according to an embodiment of the present invention.

In general, the ceiling fan 1 is advantageous to perform a forward rotation (R) when it is determined that cooling is required in the indoor space. In addition, it is advantageous that the ceiling fan 1 performs reverse rotation (R ') when it is determined that heating is required. This is because it is possible to maximize the cooling or heating effect.

Referring to FIG. 8, when the ceiling fan 1 performs forward rotation in a clockwise direction R. Referring to FIG. In the indoor space, the airflow direction is closer to the center portion of the ceiling fan 1, and the downward airflow is formed, and the farther upstream air is formed.

That is, when the ceiling fan 1 performs the forward rotation, the air near the ceiling fan 1 is pushed downward by the blades 100 and 200, and the air near the indoor side wall relatively far from the ceiling fan 1 is It is possible to flow near the center of the ceiling fan 1 in which the negative pressure is generated by the air flow flowing from the lower part of the room.

Therefore, when the cooling mode is performed, when the ceiling fan 1 performs the forward rotation, the cooling effect can be maximized because the ceiling fan 1 can be circulated to push out the hot air to the outside.

On the other hand, when the heating mode is performed, since the room temperature generally forms a low temperature, the warm air discharged through the air conditioning product naturally forms an upward airflow due to the temperature difference.

Thus, the ceiling fan 1 may perform reverse rotation (R ′) in the heating mode. According to the reverse (R ') rotation, the air flow is forced to the air near the center of the ceiling fan (1) by the rotation of the blades (100,200) to the upper side of the room can be a downward air flow on the indoor side wall. H)

According to this, the ceiling fan 1 can eliminate the phenomenon that the warm air discharged from other air-conditioning products by the cold room temperature to the vicinity of the ceiling, and can be circulated to force the air near the ceiling downward into the room. Therefore, there is an advantage that the heating effect is maximized.

The air conditioning product may include an air conditioner, an air cleaner, a dehumidifier, a humidifier, a general fan, a circulator, a heating device, and the like.

For example, the ceiling fan 1 may be installed on the indoor ceiling. In addition, a plurality of air conditioning products may be installed at different locations in the room.

in detail. A wall-mounted air conditioner D1 may be installed on the indoor side wall. In addition, an air cleaner D2 or a humidifier may be installed in the other space of the room standing up from the ground.

On the other hand, as described above, the ceiling fan 1 may operate in conjunction with at least one of the air conditioner (D1), the air cleaner (D2), the humidifier.

At this time, the ceiling fan 1, the air conditioner (D1) and the air purifier (D2) may share the indoor air environment set by the user.

That is, the ceiling fan 1 may be linked with various air conditioning products installed in the indoor space and form a network. And the air conditioning products belonging to the network can be integrated operation with the same user set value.

That is, all the air conditioning products installed in the indoor space can be linked to control the indoor air conditioning environment uniformly and comprehensively.

According to this, since the operation of each air-conditioning product on the indoor ceiling, wall, ground, etc., the indoor air circulation is made faster and the cooling or heating effect can be improved.

That is, according to the cooling mode or the heating mode, it is possible to quickly reach the room temperature to the set temperature, there is an advantage that the air cleaning time is also faster. Therefore, the user M has a merit of quickly feeling the comfort in the indoor air environment.

In addition, at the location where each air-conditioning product is installed, it detects the amount of dust, temperature and the like and operates to reach a user set value, thereby eliminating blind spots and creating a uniform indoor air environment as a whole.
