Description

air purifier

[0001] The present disclosure relates to an air purifier, and more particularly, to an air purifier having a sheet device disposed on the upper side for discharging purified air.

[0002] An air purifier is a device that creates air flow and filters the flowing air to increase the cleanliness of the air within a certain space.

[0003] The air purifier may have a configuration in which an inlet is formed on one side, an outlet is formed on the other side, and a filter is placed inside.

[0004] The air purifier can have an outlet formed at the top so that the filtered air is not delivered directly to the user.

[0005] Korean registered patent KR 10-2600644 B1 discloses an air purifier having an outlet formed at the top.

[0006] Korean Patent Publication No. KR 10-2022-7014516 A discloses an air purifier equipped with a pet mode and a control method thereof. Korean Patent Publication No. KR 10-2022-7014516 A increases airflow when operating in pet mode. In particular, it seeks to enhance deodorizing performance by increasing the airflow of the lower air purification module.

[0007] However, in households where pets such as cats live in the area where the air purifier is installed, there is a risk that the pets will climb up to the upper area of ​​the air purifier and cause the air purifier to tip over.

[0008] Additionally, if a pet is located above where the outlet is formed, it may obstruct the flow of clean air emitted by the air purifier.

[0009] Additionally, there is a problem that pets may become stressed due to vibrations or noise caused by the operation of the air purifier.

[0010] Previous literature failed to prevent air purifiers from tipping over due to pet movements. Furthermore, these studies did not provide adequate resting spaces or services for pets.

[0011] The purpose of the present disclosure is to provide an air purifier that creates a space where a pet can rest without interfering with the function of the air purifier.

[0012] The purpose of the present disclosure is to provide an environment in which a pet can rest comfortably by controlling noise and vibration caused by an air purifier when the pet climbs on top of the air purifier.

[0013] The purpose of the present disclosure is to provide an air purifier that can remove floating hair or dust without startling the pet when the pet gets off the air purifier.

[0014] The purpose of the present disclosure is to provide an air purifier having a structure that minimizes external noise in a resting space for a pet placed on one side of the air purifier.

[0015] The purpose of the present disclosure is to provide an air purifier that minimizes air flow toward a pet resting area located on one side of the air purifier.

[0016] The purpose of the present disclosure is to provide an air purifier having various functions such as measuring the weight of a pet, a heating function, and measuring the usage time, and capable of understanding the condition and lifestyle patterns of a pet.

[0266] The pressurizing portion (284) of the middle plate (280) is arranged to be in contact with the weight sensor (244). When a pet is placed on the upper side of the upper part (250), at least one of the plurality of pressurizing portions (284) can press the corresponding weight sensor (244). Accordingly, the weight of the pet placed on the upper side of the upper part (250) can be measured.

[0267] When force is applied to one side of the upper part (250), the upper part (250) in the area where the force is applied can move downward. At this time, the middle plate (280) arranged on one side also moves downward.

[0268] The air purifier (1) can perform air purification operation even when a pet is positioned on the seat device (200) by positioning the seat device (200) on the upper side of the main body (100).

[0269] Furthermore, by placing the resting area in a high space, the possibility of pets entering the resting area was increased. In particular, reflecting the characteristic of cats who like to climb to high places, a space for cats to rest was incorporated on the upper side of the air purifier (1).

[0270] The height of the seat device (200) is similar to that of a bed, providing a resting space at eye level with the cat owner. This has the effect of enhancing the happiness and comfort of the pet.

[0271] According to the present disclosure, there is an advantage in that a single product simultaneously provides a resting space for pets and air purification functions, thereby eliminating the need for additional products.

[0272] In addition, reflecting the characteristics of cats that like to wrap themselves around the body and prefer warm spaces, the air purifier (1) provides a heating function using a heater (264).

[0273] Additionally, functions such as measuring a cat's weight and usage time are applied to the space, allowing the cat's daily life patterns to be naturally measured, and cat owners can utilize this information to manage their cat's health. The measured data can be checked and managed through the application.

[0274] The air purifier (1) features various functions, such as pet weight measurement, heating function, and usage time measurement, and can analyze the pet's condition and lifestyle patterns. Users can run the application on their mobile devices to check real-time weight measurement results, weight measurement history, and other information, and control the heating temperature.

[0301] FIG. 13 is a block diagram of an air purifier according to an embodiment of the present disclosure.

[0302] Referring to FIG. 13, an air purifier according to an embodiment of the present disclosure may include a control unit (1340) and a fan drive unit (1380) that drives a fan (140) according to the control of the control unit (1340).

[0303] At least some of the internal blocks of the air purifier illustrated in Fig. 13, such as the control unit (1340) and the fan drive unit (1380), may be placed inside the main body (100). For example, the control unit (1340) may be mounted on a printed circuit board (123) placed in a space formed by the lower housing (114) placed on the upper side of the base (110).

[0304] A fan (140) is installed inside the main body (100) to control the flow of indoor air that is purified while passing through a filter (101) and then discharged into the indoor space. The fan (140) can be rotatably arranged between the inlet (106) and the outlet (112) to form an air flow from the inlet (106) to the outlet (112).

[0305] The fan motor (148) rotates the fan (140) according to a control signal received from the fan driving unit (1380). The rotation of the fan (140) is controlled by the fan driving unit (1380), and the operation of the fan driving unit (1380) is controlled by the control unit (1340). The fan driving unit (1380) may be equipped with a power conversion device such as an inverter to operate the fan motor (148).

[0306] The filter (101) removes foreign substances in the air flowing into the inlet (106). The filter (101) may include a pre-filter that filters foreign substances in the air, a HEPA filter that collects pollutants in the air, a deodorizing filter that removes odors in the air, etc. The pre-filter has a grill formed to primarily filter foreign substances in the air being sucked in. The HEPA filter collects pollutants in the sucked in air, and the deodorizing filter can remove odors in the sucked in air.

[0307] Meanwhile, the air purifier may include a memory (1330), a sensing unit (1350), a communication unit (1370), etc.

[0308] The memory (1330) may store data for controlling the operation of the air purifier, data detected or measured through the sensing unit (1350) during operation, and data received through the communication unit (1370). Meanwhile, the air purifier may include a buffer for temporarily storing data, and the buffer may be included in the control unit (1340) or the memory (1330).

[0309] The control unit (1340) can process various data received through the communication unit (1370) to update the memory (1145). For example, if the data input through the communication unit (1370) is update data for a driving program pre-stored in the memory (1330), the memory (1330) can be updated using this, and if the input data is a new driving program, the memory (1330) can be additionally stored therein.

[0310] The sensing unit (1350) can measure the level of air pollution or sense the operating status of the air purifier by including one or more sensors.

[0311] The control unit (1340) can control the flow of data input or output to the air purifier and generate and apply a control command based on data input from the sensing unit (1350).

[0312] Meanwhile, the air purifier can communicate with other devices such as servers, home appliances, and terminals through the communication unit (1370) to transmit and receive data.

[0313] The input unit (1310) can receive various user commands related to the operation of the air purifier and transmit a control signal corresponding to the input command to the control unit (1340). The input unit (1310) can include a touch pad, physical buttons, etc.

[0314] The output unit (1320) may be equipped with a display device such as a display (not shown) or a light emitting diode (LED) (not shown). For example, the output unit (1320) may display information such as the operating status of the air purifier, the occurrence of an error, the indoor temperature, and the target temperature.

[0315] The output unit (1320) may be equipped with an audio device such as a speaker (not shown) or a buzzer (not shown). For example, the output unit (1320) may output a sound effect regarding the operating status of the air purifier and may output a predetermined warning sound when an error occurs.

[0316] The control unit (1340) may be connected to each component of the air purifier. For example, the control unit (1340) may transmit and / or receive signals between each component of the air purifier and control the overall operation of each component.

[0317] The control unit (1340) may include at least one processor, and may control the overall operation of the air purifier using the processor included therein. Here, the processor may be a general processor, such as a central processing unit (CPU). Of course, the processor may also be a dedicated device, such as an ASIC, or another hardware-based processor.

[0318] Meanwhile, the control unit (1340) can control the overall operation of the air purifier and control a series of air purification processes such as intake of outside air and discharge of purified air.

[0319] The control unit (1340) can perform an air purification process according to a preset algorithm, and the fan drive unit (1380) can drive the fan (140) according to the control of the control unit (1340). The fan motor (148) is operated by a control signal sent from the fan drive unit (1380). The fan drive unit (1380) can control the rotation speed and direction of the fan (140) based on the control signal generated to improve air characteristics.

[0320] When the fan driver (1380) drives the fan (140) by rotating the fan motor (148), external air can be sucked into the air purifier through the inlet (106). The sucked air can be purified while passing through the filter (101) and then discharged to the outside through the outlet (112).

[0321] Meanwhile, the air purifier may be equipped with a temperature control function for pets. For example, a heater (264) is provided within the seat device (200). The control unit (1340) can operate the heater (264) to provide a heating function for pets positioned on the seat device (200).

[0322] The control unit (1340) can receive sensing data of the weight sensor (244) from the printed circuit board (246) of the seat device (200) and determine whether the pet is in the seat device (200). The control unit (1340) can control the fan (140) and the heater (264) based on whether the pet is in the seat device (200).

[0323] Additionally, one or more temperature sensors (not shown) may be placed in the sheet device (200), and the printed circuit board (246) may transmit sensing data of the temperature sensor to the control unit (1340).

[0324] According to an embodiment, the seat device (200) may include a separate seat control unit. The seat control unit may be mounted on a printed circuit board (246). The seat control unit may control the heater (264) of the seat device (200). The seat control unit may communicate with the control unit (1340) and operate the heater (264) based on a signal received from the control unit (1340).

[0325] The seat control unit can transmit data from the sensors to the control unit (1340). In addition, the seat control unit can receive sensing data from the weight sensor (244) and determine whether the pet is in the seat device (200). The seat control unit can receive sensing data from the temperature sensor and determine the temperature of the seat device (200) and / or the pet.

[0326] Meanwhile, the detection frequency range of dogs is 45 kHz to 67 kHz, and that of cats is 55 kHz to 79 kHz, so pets are more sensitive to the noise caused by the operation of an air purifier (1) than humans.

[0327] In particular, cats are more sensitive to motor and wind noises when an air purifier is in operation because their hearing range is higher than that of humans. Therefore, by controlling the air volume according to the cat's behavior, the cat can use the air purifier (1) more comfortably without being stressed or traumatized by the air purifier (1).

[0328] The control unit (1340) can reduce the wind volume to minimize noise and vibration when a pet is located on the upper side of the seat device (200).

[0329] The seat device (200) includes a weight sensor (244) that detects the presence of a pet. The control unit (1340) recognizes whether a pet cat is present in the cat resting area of ​​the seat device (200) through the weight sensor (244) and controls the fan (140). The weight sensor (244) may be placed on the upper side of the lower body (211). The weight sensor (244) may detect the weight of the upper side of the upper part (250).

[0330] For example, the weight sensor (244) may be a load cell (244). Hereinafter, a case in which a load cell (244) is used will be described as an example.

[0331] The load cell (244) can measure the time the cat climbs onto the seat device (200) and the time the cat climbs off the seat device (200). In addition, the control unit (1340) can measure the resting pattern of the pet using the load cell (244).

[0332] The air purifier (1) can measure the point at which the cat goes up and down through the load cell (244) and control the air purifier wind speed according to the logic.

[0333] The control unit (1340) can control the wind speed to the lowest level when it is determined that the cat has climbed onto the seat device (200).

[0334] Meanwhile, depending on the pet, exposure to noise levels exceeding 35 dB can be a stress factor. The control unit (1340) can control the fan (140) to a wind speed that generates noise levels lower than 35 dB.

[0335] Additionally, the control unit (1340) can control the airflow over time so as to remove floating hair or dust without startling the pet when the pet gets off the seat device (200).

[0336] The control unit (1340) can increase the wind speed to effectively remove hair, dust, etc. floating around the area when it determines that the cat has gone down. However, since the cat may be startled by a sudden change in wind speed, the control unit (1340) can remove the floating hair without startling the cat by adjusting the wind speed after a certain period of time.

[0337] Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the drawings.

[0338] Fig. 14 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and exemplifies a first wind volume control mode when a pet such as a cat climbs onto the air purifier (1).

[0339] First, the air purifier (1) operates at the wind speed set by the customer (S1410).

[0340] For example, a customer can select any one of multiple airflow modes provided by the air purifier (1).

[0341] FIG. 15 is a drawing for reference in a description of wind speed modes of an air purifier according to an embodiment of the present disclosure, and illustrates noise measurement results for each wind speed mode.

[0342] Figure 15 illustrates the air purification wind speed modes of stages 1 to 3 and an additional sleep mode.

[0343] Figure 15 (a) shows the noise measurement results of the third stage (strong) with the strongest wind volume, and the noise level when the wind volume is controlled in the third stage can be 48.02 dB.

[0344] Figure 15 (b) shows the noise measurement results of the second stage (medium) with medium wind volume, and the noise level when the wind volume is controlled in the second stage can be 37.33 dB.

[0345] Figure 15 (c) shows the noise measurement results of stage 1 (weak) with the weakest wind volume, and the noise level when the wind volume is controlled at stage 1 can be 29.21 dB.

[0346] Figure 15 (d) illustrates the noise measurement results in sleep mode, and the noise level when the wind speed is controlled at level 1 can be 24.21 dB. Sleep mode is an additional mode for user sleep, and the normal air purification wind speed mode can provide levels 1 to 3.

[0347] Additionally, an automatic driving mode may be provided as an additional mode. For example, the automatic driving mode may be a mode in which the air volume is automatically adjusted according to air quality.

[0348] Meanwhile, if a weight is detected from the load cell (244) and a signal is generated (S1420), the control unit (1340) can determine that the pet has climbed onto the seat device (200).

[0349] If there is a signal from the load cell (244) (S1420), the control unit (1340) can control the airflow at a preset airflow rate (S1430). The fan (140) can rotate at a first rotation speed corresponding to the preset airflow rate (S1430). The fan (140) can rotate at a first rotation speed corresponding to an airflow rate lower than a preset reference value (S1430).

[0350] For example, if the reference value is 35 dB, the control unit (1340) can control the fan (140) to a wind volume that generates noise less than 35 dB. In the example of Fig. 15, the noise level when the wind volume is controlled in step 1 is 29.21 dB, so the control unit (1340) can control the fan (140) to rotate at the first rotation speed corresponding to step 1.

[0351] Meanwhile, the first rotation speed may be a rotation speed corresponding to the lowest wind speed mode among the plurality of wind speed modes provided.

[0352] If there is a signal from the load cell (244) (S1420), the control unit (1340) can control the minimum airflow (S1430). In the example of Fig. 15, since stage 1 is the minimum airflow in the normal air purification airflow mode, the control unit (1340) can control the fan (140) to rotate at the first rotation speed corresponding to stage 1.

[0353] Even while the fan (140) is rotating at the first rotation speed, the control unit (1340) can determine whether the pet is still on the seat device (200) based on the signal of the load cell (244) (S1440).

[0354] If the weight is detected by the load cell (244) and a signal continues (S1440), the control unit (1340) can maintain the current control state (S1430). The first wind volume control mode (S1400) may be a mode that controls the wind volume below a reference value or to the minimum wind volume (S1430) based on the signal of the load cell (244) (S1420, S1440).

[0355] Meanwhile, if no weight is detected from the load cell (244) and there is no signal corresponding to the detected weight (S1440), the mode may be switched to the second wind volume control mode (S1600).

[0356] Fig. 16 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and exemplifies a second wind volume control mode when a pet such as a cat gets off the air purifier (1).

[0357] Referring to FIG. 16, in the first wind volume control mode (S1400), while the fan (140) rotates at the first rotation speed, the control unit (1340) can determine whether the pet is still on the seat device (200) based on the signal of the load cell (244) (S1440).

[0358] When a pet is not detected by the load cell (244) while the fan (140) is rotating at the first rotation speed (S1440), the control unit (1340) can count the time during which the pet is not detected (S1610).

[0359] If no weight is detected in the load cell (244) and there is no signal corresponding to the detected weight (S1440), the control unit (1340) can determine that the pet has come down and count the time during which the pet is not detected (S1610).

[0360] If the time (first hour) during which no pet is detected in the load cell (244) exceeds the set time (S1620), the control unit (1340) can change the wind speed to the wind speed mode set by the customer (S1650). The fan (140) can rotate at a rotation speed corresponding to the wind speed mode set by the user.

[0361] That is, when the load cell (244) determines that the pet has come down because the pet is not detected, the air volume is not changed, and the air volume change can be postponed for a set period of time. Accordingly, the pet can be prevented from coming down from the seat device (200) and being startled by the noise caused by the operation of the fan (140) near the main body (100). In addition, the set period of time can be the time when the pet moves away from the air purifier (1).

[0362] Meanwhile, if a pet moves around, under, and around the air purifier (1), it may be necessary to remove hair, dust, etc. The control unit (1340) can increase the wind speed to effectively remove hair, dust, etc. floating around the air purifier (1). However, since the pet cat may be startled by a sudden change in wind speed, the control unit (1340) can remove the floating hair by adjusting the wind speed after a certain period of time so as not to startle the pet cat.

[0363] If the time (first hour) during which no pet is detected in the load cell (244) exceeds the set time, the control unit (1340) can increase the rotation speed of the fan (140).

[0364] Additionally, the control unit (1340) can further increase the rotation speed of the fan (140) after a predetermined time.

[0365] The control unit (1340) can increase the rotation speed of the fan (140) to a rotation speed corresponding to the maximum wind speed mode.

[0366] Thereafter, the control unit (1340) can change the rotation speed of the fan (140) to correspond to the maximum wind speed mode and then correspond to the wind speed set by the user.

[0367] FIG. 17 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure, and a second wind volume control mode of another embodiment is exemplified.

[0368] The embodiment of Fig. 17 differs from the embodiment of Fig. 16 in that it further includes a wind volume change step (S1630, S1640). Accordingly, the remaining operations can be performed identically.

[0369] If a pet is not detected in the load cell (244) (S1440), the control unit (1340) can count the time during which the pet is not detected (S1610).

[0370] If the time (first hour) during which no pet is detected by the load cell (244) exceeds the set time (S1620), the control unit (1340) can change the wind speed from level 1 (weak) to level 2 (medium) (S1630). As the wind speed mode changes from level 1 (weak) to level 2 (medium), the fan (140) can rotate at a second rotation speed that is faster than the first rotation speed.

[0371] The control unit (1340) can control the wind speed at level 2 (medium) and then change it to a stronger level 3 (strong) (S1650). As the wind speed mode changes from level 2 (medium) to level 3 (strong), the fan (140) can rotate at a third rotation speed that is faster than the second rotation speed.

[0372] The fan (140) can rotate at a second rotation speed for a predetermined time. In addition, after rotating at the second rotation speed for a predetermined time, the fan (140) can rotate at a third rotation speed that is faster than the second rotation speed.

[0373] By gradually increasing the wind speed, you can prevent your pet from being startled, while improving the air purification performance with strong wind speed.

[0374] Thereafter, the control unit (1340) can change the wind volume to a wind volume mode set by the customer (S1650). The fan (140) can rotate at a rotation speed corresponding to the wind volume mode set by the user.

[0375] The fan (140) can rotate at the third rotation speed for a predetermined time. In addition, after rotating at the third rotation speed for a predetermined time, the fan (140) can rotate at a rotation speed corresponding to a wind speed mode set by the user.

[0376] Meanwhile, the time for which the fan (140) rotates at the second rotation speed and the time for which it rotates at the third rotation speed may be set differently. For example, in order to maximize air purification performance, the second time for which it rotates at the third rotation speed may be set longer than the first time for which it rotates at the second rotation speed.

[0377] According to an embodiment, the control unit (1340) can change the wind speed from level 1 (weak) to level 3 (strong) after a set time has elapsed (S1650).

[0378] In addition, if the time for which a pet is not detected by the load cell (244) exceeds a set time (S1620), the control unit (1340) can communicate with the server and / or other devices via the communication unit (1370). The control unit (1340) can directly communicate with the robot cleaner (not shown) or request cleaning of the robot cleaner via another device such as a server. Accordingly, the robot cleaner can move near the air purifier (1) and perform cleaning work.

[0379] Meanwhile, a base supporter (300) may be coupled to the lower surface of the main body (100). In addition, an auxiliary panel (310) may be coupled to one side of the base supporter (300).

[0380] A pet that has descended from the seat device (200) on the upper side of the main body (100) may be positioned on the auxiliary panel (310). In addition, if a stepping member (320) is mounted on the auxiliary panel (310), the possibility of the pet being on the stepping member (320) may increase. Therefore, it is necessary to control the airflow by considering whether the base supporter (300) and the auxiliary panel (310) are combined.

[0381] Whether the main body (100), base supporter (300), and auxiliary panel (310) are connected can be determined based on the electrical connection relationship. For example, the control unit (1340) can determine that the main body (100) and base supporter (300) are connected when current flows through the connector (304). The control unit (1340) can determine that the base supporter (300) and auxiliary panel (310) are connected when current flows through the auxiliary connector (312).

[0382] Alternatively, a separate sensor may be provided to determine whether the main body (100), base supporter (300), and auxiliary panel (310) are connected.

[0383] FIG. 18 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure.

[0384] Referring to FIG. 18, the control unit (1340) can determine whether the pet is still on the seat device (200) based on the signal of the load cell (244) (S1810).

[0385] When the fan (140) rotates at the first rotation speed and the load cell (244) does not detect a pet (S1810), the control unit (1340) can determine whether the auxiliary panel (310) is engaged (S1815).

[0386] Additionally, the control unit (1340) can count the time during which the pet is not detected by the load cell (244) while the fan (140) rotates at the first rotation speed (S1820, S1830).

[0387] If the counted time exceeds the set time (S1825, S1835), the control unit (1340) can change the wind speed from level 1 (weak) to level 2 (medium) (S1840). As the wind speed mode changes from level 1 (weak) to level 2 (medium), the fan (140) can rotate at a second rotation speed that is faster than the first rotation speed.

[0388] Here, the setting time may vary depending on whether the auxiliary panel (310) is connected or not.

[0389] When the auxiliary panel (310) is combined, the first setting time is applied (S1825), and when the auxiliary panel (310) is combined, the first setting time can be applied (S1835).

[0390] The first setting time is set longer than the second setting time, so that when the auxiliary panel (310) is combined, it can provide sufficient time for the pet to move away from the main body (100) and the auxiliary panel (310).

[0391] The control unit (1340) can control the wind speed at level 2 (medium) and then change it to a stronger level 3 (strong) (S1850). As the wind speed mode changes from level 2 (medium) to level 3 (strong), the fan (140) can rotate at a third rotation speed that is faster than the second rotation speed.

[0392] Meanwhile, the time for rotating at the third rotation speed can be set longer than the time for rotating at the second rotation speed.

[0393] Thereafter, the control unit (1340) can change the wind volume to a wind volume mode set by the customer (S1850). The fan (140) can rotate at a rotation speed corresponding to the wind volume mode set by the user.

[0394] According to an embodiment, when the counted time exceeds the set time (S1825, S1835), the fan (140) can immediately rotate at a rotation speed corresponding to the wind speed mode set by the user.

[0395] Meanwhile, the air purifier (1) may further include an auxiliary panel sensor (not shown) that detects the location of a pet on the upper side of the auxiliary panel. The presence of the auxiliary panel sensor allows for more precise control because the location of the pet can be more accurately identified.

[0396] FIG. 19 is a flowchart illustrating an operating method of an air purifier according to an embodiment of the present disclosure.

[0397] Referring to FIG. 19, when the fan (140) rotates at the first rotation speed and a pet is not detected by the load cell (244) (S1910), the control unit (1340) can determine whether the auxiliary panel (310) is engaged (S1920).

[0398] If the auxiliary panel (310) is not connected (S1920), the control unit (1340) can count the time during which the pet is not detected by the load cell (244) (S1940).

[0399] If the auxiliary panel (310) is connected (S1920), the control unit (1340) can check whether a pet is detected by the auxiliary panel sensor (S1930).

[0400] When a pet is detected by the auxiliary panel sensor (S1930), the control unit (1340) does not count the time during which the pet is not detected.

[0401] If a pet is not detected by the auxiliary panel sensor (S1930), the control unit (1340) can count the time during which the pet is not detected by the load cell (244) (S1940).

[0402] If the counted time exceeds the set time (S1950), the control unit (1340) can change the wind speed from level 1 (weak) to level 2 (medium) (S1960). As the wind speed mode changes from level 1 (weak) to level 2 (medium), the fan (140) can rotate at a second rotation speed that is faster than the first rotation speed.

[0403] The control unit (1340) can control the wind speed at level 2 (medium) and then change it to level 3 (strong) (S1970). As the wind speed mode changes from level 2 (medium) to level 3 (strong), the fan (140) can rotate at a third rotation speed that is faster than the second rotation speed.

[0404] Meanwhile, the time for rotating at the third rotation speed can be set longer than the time for rotating at the second rotation speed.

[0405] Thereafter, the control unit (1340) can change the wind volume to a wind volume mode set by the customer (S1980). The fan (140) can rotate at a rotation speed corresponding to the wind volume mode set by the user.

[0406] Although the preferred embodiments of the present disclosure have been illustrated and described above, the present disclosure is not limited to the specific embodiments described above, and it goes without saying that various modifications can be made by a person having ordinary skill in the art to which the present disclosure pertains without departing from the gist of the present disclosure as claimed in the claims.
