DETAILED DESCRIPTION

[0060] Hereinafter, the present application will be described in detail through exemplary embodiments. However, it should be understood that elements, structures, and features in one embodiment can be beneficially incorporated in other embodiments as well without further recitation.

[0061] In the present application, an air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and supplies refrigerant to air that has been adjusted and heat-exchanged.

[0062] The compressor compresses refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0063] The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by exchanging heat with a material to be cooled using latent heat of evaporation of the refrigerant. Throughout the cycle, the air conditioner can adjust the temperature of an indoor space.

[0064] The air conditioner includes an air conditioner indoor unit and an air conditioner outdoor unit, the air conditioner outdoor unit refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the air conditioner indoor unit includes an indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0065] The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger serves as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0066] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0067] The air conditioner indoor unit of the embodiments of the present application can be a wall-mounted indoor unit, but the present application is not limited thereto.

[0068] Referring to Figures 1-16 The air conditioner indoor unit according to the embodiments of the present application includes a housing, a base, a heat exchanger, and an aromatherapy mechanism.

[0069] The directions described herein are based on the direction in which a user faces the air conditioner indoor unit, in which the left side and the right side are distinguished from each other in the direction in which the user faces the air conditioner indoor unit, the side of the air conditioner indoor unit facing the user when the air conditioner indoor unit is in use is defined as the front side, the opposite side is defined as the rear side, and the upper side and the lower side of the air conditioner indoor unit when the air conditioner indoor unit is generally normally operating are defined to distinguish between the upper and lower sides.

[0070] In this embodiment, the housing forms the overall appearance of the air conditioner indoor unit, the housing is provided with an air outlet and an air inlet, the air outlet is a long strip shape provided along the length direction of the air conditioner indoor unit. The air outlet can be provided on the lower side of the housing, and the air inlet is provided on the upper side of the housing.

[0071] The housing is provided on the base, the inside of the base is provided with a heat exchange air duct, and the heat exchange air duct connects the air inlet and the air outlet on the housing. The indoor air enters the housing from the air inlet, and is blown out from the air outlet after passing through the heat exchange air duct.

[0072] The indoor heat exchanger can be provided in the heat exchange air duct and on the side of the heat exchange air duct close to the air inlet. The indoor heat exchanger is used to absorb heat from the air introduced into the air inlet or transfer heat to the air, and the indoor air is blown out from the air outlet after passing through the heat exchange air duct.

[0073] The heat exchange fan can be arranged in the heat exchange air duct, and is configured to blow air, so that indoor air can flow from the air inlet to the air outlet.

[0074] By operating the heat exchange fan, air outside the casing is introduced into the casing through the air inlet, and heat exchange is performed by the indoor heat exchanger to form a heat exchange air flow, and the heat exchange fan is operated to drive the heat exchange air flow to be output outward through the air outlet.

[0075] A water pan can be arranged below the indoor heat exchanger, and is configured to collect condensed water in the indoor heat exchanger. The water pan can be connected with a drain pipe extending to the outside of the base, so as to drain the condensed water to the outside of the air conditioner indoor unit. In some embodiments, the water pan can be integrally formed with the base, so as to reduce the cost and improve the installation efficiency.

[0076] The casing of the air conditioner indoor unit is provided with a fresh air module, which is configured to draw fresh air from the outside, and the fresh air flows through the fresh air module and then flows to the indoor through the fresh air outlet.

[0077] The aromatherapy mechanism is arranged in the casing, and is arranged between the air inlet side of the indoor heat exchanger and the air inlet of the casing, so that the essential oil in the aromatherapy mechanism is better diffused in the casing.

[0078] The aromatherapy mechanism includes an aromatherapy tank 1, a magnet 2, a cotton stick 3, a sliding rail 4, a support rod 5, an ultrasonic atomizer 6, and an electromagnet.

[0079] The aromatherapy tank 1 is arranged on the inner side of the casing, and is a tank-shaped container. The aromatherapy tank 1 stores essential oil therein, and one side of the aromatherapy tank 1 is provided with an aromatherapy opening 11. The magnet 2 is arranged on the side wall of the aromatherapy tank 1 provided with the aromatherapy opening 11. The cotton stick 3 is inserted into the aromatherapy tank 1 through the aromatherapy opening 11, and contacts the essential oil in the aromatherapy tank 1, so as to be used for absorbing the essential oil. The inner side of the casing is provided with the sliding rail 4. One end of the support rod 5 is matched with the sliding rail 4, so that the support rod 5 can move back and forth along the sliding rail 4. The ultrasonic atomizer 6 is arranged on the support rod 5, and can move with the support rod 5. The ultrasonic atomizer 6 is arranged corresponding to the cotton stick 3, and can atomize the essential oil on the cotton stick 3 after contacting the cotton stick 3. The electromagnet is connected to the support rod 5, and the position of the electromagnet is arranged corresponding to the magnet 2. The electromagnet can be attracted to the magnet 2 after being electrified.

[0080] When the electromagnet is electrified, the electromagnet is attracted to the magnet 2 to drive the support rod 5 to slide along the sliding rail 4 to the direction close to the cotton stick 3, and the support rod 5 drives the ultrasonic atomizer to contact the cotton stick 3 to atomize the essential oil on the cotton stick 3.

[0081] In this embodiment, the cotton stick 3 absorbs the aromatherapy essential oil from one end of the aromatherapy tank 1 to the other end of the aromatherapy tank 1. Then the electromagnet is powered to control the ultrasonic atomizer 6 to contact the cotton stick 3 at the other end of the aromatherapy tank 1, so as to atomize the aromatherapy essential oil on the cotton stick 3. The aromatherapy essential oil is precisely controlled to be released into the room, thereby improving the utilization rate of the aromatherapy essential oil.

[0082] In some embodiments, the aromatherapy mechanism further comprises an elastic member 9, which can be provided as a spring. The elastic member 9 is arranged between the support rod 5 and the aromatherapy tank 1, and is used to provide a buffering force for the support rod 5.

[0083] When the electromagnet is powered, the electromagnet is attracted to the magnet 2 to drive the support rod 5 to slide along the slide rail 4 towards the cotton stick 3. When the support rod 5 slides to abut against the elastic member 9, the elastic member 9 provides a buffering force to the support rod 5, which is smaller than the attractive force between the electromagnet and the magnet 2. Thus, the support rod 5 continues to slide towards the cotton stick 3 until the ultrasonic atomizer 6 contacts the cotton stick 3, and the support rod 5 stops moving. At this time, the ultrasonic atomizer 6 is powered, and the support rod 5 drives the ultrasonic atomizer to contact the cotton stick 3 to atomize the aromatherapy essential oil on the cotton stick 3. The ultrasonic atomizer 6 converts electrical energy into ultrasonic wave energy to atomize the aromatherapy liquid into aromatherapy mist particles, and the power of the ultrasonic atomizer 6 can be adjusted to control the frequency of the ultrasonic wave and thus the atomization rate of the aromatherapy essential oil.

[0084] When the electromagnet is powered, the electromagnet is attracted to the magnet 2 to drive the support rod 5 to slide along the slide rail 4 towards the cotton stick 3. When the support rod 5 slides to abut against the elastic member 9, the elastic member 9 provides a buffering force to the support rod 5, which is smaller than the attractive force between the electromagnet and the magnet 2. Thus, the support rod 5 continues to slide towards the cotton stick 3 until the ultrasonic atomizer 6 contacts the cotton stick 3, and the support rod 5 stops moving. At this time, the ultrasonic atomizer 6 is powered, and the support rod 5 drives the ultrasonic atomizer to contact the cotton stick 3 to atomize the aromatherapy essential oil on the cotton stick 3. The ultrasonic atomizer 6 converts electrical energy into ultrasonic wave energy to atomize the aromatherapy liquid into aromatherapy mist particles, and the power of the ultrasonic atomizer 6 can be adjusted to control the frequency of the ultrasonic wave and thus the atomization rate of the aromatherapy essential oil.

[0085] In some embodiments, the aromatherapy mechanism further comprises a containing shell 10. The containing shell 10 is connected to the inside of the shell, and the aromatherapy tank 1 is inserted into the containing shell 10. After the aromatherapy tank 1 is inserted into the containing shell 10, a gap 104 is provided between one side of the aromatherapy tank 1 and the containing shell 10.

[0086] One side of the aromatherapy tank 1 is connected with a clamping jaw 101, which can be integrally formed with the aromatherapy tank 1. The clamping jaw 101 is arranged in the gap 104.

[0087] The clamping jaw 101 is an elastic clamping jaw 101. When the aroma pot 1 is inserted into the accommodating shell 10, the clamping jaw 101 is pressed against the inner side wall of the accommodating shell 10 to press the aroma pot 1 and the accommodating shell 10 tightly, thereby limiting the movement of the aroma pot 1 and preventing the aroma pot 1 from sliding out of the shell body at will.

[0088] By pressing the clamping jaw 101, the clamping jaw 101 is elastically deformed to be separated from the inner side wall of the accommodating shell 10, so that the clamping jaw 101 does not limit the aroma pot 1. At this time, the aroma pot 1 can be pulled out of the accommodating shell 10 to facilitate replacement of the aroma liquid in the aroma pot 1 and cleaning of the aroma pot 1.

[0089] In some embodiments, the accommodating shell 10 extends in the direction close to the support rod 5 to have an extension rod 102, and the middle part of the extension rod 102 is provided with a cavity 103. The support rod 5 extends in the direction close to the accommodating shell 10 to have a connecting rod 51, and the connecting rod 51 is inserted into the cavity 103 of the extension rod 102. The extension rod 102 can guide the sliding of the connecting rod 51. When the support rod 5 slides along the sliding rail 4, the connecting rod 51 slides in the cavity 103 to facilitate more accurate control of the corresponding cooperation between the ultrasonic atomizer 6 and the cotton stick 3.

[0090] In some embodiments, the elastic member 9 is arranged in the cavity 103 of the extension rod 102. The elastic member 9 can be a spring. The end of the extension rod 102 away from the support rod 5 is closed, that is, the end of the cavity 103 away from the support rod 5 is closed. The spring is arranged in the cavity 103, and one end of the cavity 103 is closed to limit the spring. Specifically, the end of one end of the spring abuts against the closed end of the cavity 103 to prevent the spring from moving in the cavity at will and facilitate the limitation of the position of the spring. The connecting rod 51 is inserted into the cavity 103 from the opposite end of the closed end of the cavity 103. When the connecting rod 51 is inserted into the cavity 103, the spring is sleeved on the connecting rod 51, so that the spring buffers the connecting rod 103. After the electromagnet is powered off, the spring can pop the connecting rod out of the cavity 103 by the elastic force.

[0091] When the electromagnet is powered on, the electromagnet is attracted to the magnet 2 to drive the support rod 5 to slide along the slide rail 4 to the direction of approaching the cotton stick 3. When the support rod 5 slides to abut against the elastic member 9, the elastic member 9 provides a buffering force to the support rod 5, and the buffering force is smaller than the attraction force between the electromagnet and the magnet 2. Thus, the support rod 5 continues to slide to the direction of approaching the cotton stick 3 until the ultrasonic atomizer 6 contacts the cotton stick 3, and the support rod 5 stops moving. At this time, the ultrasonic atomizer 6 is powered on, and the support rod 5 drives the ultrasonic atomizer to contact the cotton stick 3 to atomize the aromatherapy essential oil on the cotton stick 3. The ultrasonic atomizer 6 converts electrical energy into ultrasonic wave energy to atomize the aromatherapy liquid into mist particles with a diameter of 1-5 microns. The frequency of the ultrasonic wave can be controlled by adjusting the power of the ultrasonic atomizer 6, and thus the atomization rate of the aromatherapy essential oil can be controlled.

[0092] In some embodiments, the aromatherapy opening 11 is arranged on the outer side wall of the aromatherapy tank 1 on the side close to the support rod 5, and the aromatherapy opening 11 extends in the direction of approaching the support rod 5 with an extension wall 12. The magnet 2 is arranged in a ring shape, and the magnet 2 cooperates with the extension wall 12. The magnet 2 is arranged around the extension wall 12 by being sleeved on the outer side wall of the extension wall 12, so as to facilitate the fixation and positioning of the magnet 2.

[0093] In some embodiments, the aromatherapy opening 11 is arranged on the outer side wall of the aromatherapy tank 1 on the side close to the support rod 5, and the aromatherapy opening 11 extends in the direction of approaching the support rod 5 with an extension wall 12. The magnet 2 is arranged in a ring shape, and the magnet 2 cooperates with the extension wall 12. The magnet 2 is arranged around the extension wall 12 by being sleeved on the outer side wall of the extension wall 12, so as to facilitate the fixation and positioning of the magnet 2.

[0094] The two opposite sides of the aromatherapy opening 11 are provided with clamping members 13. The clamping members 13 can be arranged in an "L" shape.

[0095] The two opposite sides of the aromatherapy opening 11 are provided with clamping members 13. The clamping members 13 can be arranged in an "L" shape.

[0096] The two opposite sides of the aromatherapy opening 11 are provided with clamping members 13. The clamping members 13 can be arranged in an "L" shape.

[0097] The two opposite sides of the aromatherapy opening 11 are provided with clamping members 13. The clamping members 13 can be arranged in an "L" shape.

[0098] In some embodiments, the ultrasonic atomizer 6 includes an atomizing sheet 61 and a diaphragm 62. The atomizing sheet 61 can be a ceramic atomizing sheet, and the diaphragm 62 can be a stainless steel diaphragm.

[0099] The atomizing sheet 61 is annularly arranged, and is arranged on the inner side of the assembly hole 82 and annularly surrounds the inner side of the assembly hole 82. The middle part of the atomizing sheet 61 is provided with a through hole 611, and the diaphragm 62 is arranged in the through hole 611 in the middle part of the atomizing sheet 61.

[0100] According to the electromagnetic induction effect, when the coil 7 is supplied with current, an induced magnetic field is generated around the coil 7, and the direction of the induced magnetic field can be determined by Ampere's law. When the induced magnetic field acts on the iron core 8, the internal magnetic wall of the iron core 8 expands, the magnetic domain turns to approach the direction of the induced magnetic field and is magnetized, so that the iron core 8 has magnetic properties. After the iron core 8 is magnetized, under the magnetic attraction of the magnet 2, it moves towards the direction of the magnet 2 at a high speed, and the connecting rod 51 slides into the cavity 103 of the extension rod 102.

[0101] After the supporting rod 5 slides to abut against the elastic member 9 in the cavity 103, the elastic member 9 provides a buffering force to the supporting rod 5, and the buffering force is smaller than the attractive force between the electromagnet and the magnet 2. Therefore, the supporting rod 5 continues to slide towards the cotton stick 3 until the ultrasonic atomizer 6 contacts the cotton stick 3, and the supporting rod 5 stops moving. At this time, the ultrasonic atomizer 6 is in a powered state, the supporting rod 5 drives the ultrasonic atomizer to contact the cotton stick 3 to atomize the essential oil on the cotton stick 3. The ultrasonic atomizer 6 converts electrical energy into ultrasonic wave energy, atomizes the essential oil into particles with a diameter of 1-5 microns, and releases the particles. The frequency of the ultrasonic wave can be controlled by adjusting the power of the ultrasonic atomizer 6, so as to control the atomization rate of the essential oil.

[0102] When the electromagnet is powered off, the magnetism of the electromagnet gradually disappears, and the attractive magnetic force between the electromagnet and the magnet 2 also gradually decreases. When the attractive magnetic force between the electromagnet and the magnet 2 decreases to be smaller than the buffering force of the elastic member 9 acting on the supporting rod 5, the elastic member 9 pushes the supporting rod 5 to move away from the cotton stick 3, so as to push the ultrasonic atomizer 6 away from the cotton stick 3. At this time, the ultrasonic atomizer 6 is separated from the cotton stick 3, and the ultrasonic atomizer 6 no longer atomizes the essential oil on the cotton stick 3. By accurately controlling the essential oil, the essential oil can be released into the room, thereby improving the utilization rate of the essential oil.

[0103] Since the stainless steel diaphragm is a non-ferromagnetic material and is not affected by the induced magnetic field, it will not interfere with the normal atomization process.

[0104] In some embodiments, a plurality of essential oil mechanisms are arranged in the shell, and the plurality of different essential oil mechanisms can prevent different flavors of essential oil. The user can replace the essential oil tank 1 according to the needs, and can control the mixed combination form of different essential oils through a remote control or a controller.

[0105] Referring to Figures 1-17In some embodiments, the air conditioner indoor unit is provided with a first aromatherapy mechanism, the first aromatherapy mechanism is arranged on the inner wall of the shell, and the first aromatherapy mechanism contains first aromatherapy essential oil for releasing the first aromatherapy.

[0106] The air conditioner indoor unit is provided with a first aromatherapy mechanism, the first aromatherapy mechanism is arranged on the inner wall of the shell, and the first aromatherapy mechanism contains first aromatherapy essential oil for releasing the first aromatherapy.

[0107] The air conditioner indoor unit is provided with a first aromatherapy mechanism, the first aromatherapy mechanism is arranged on the inner wall of the shell, and the first aromatherapy mechanism contains first aromatherapy essential oil for releasing the first aromatherapy.

[0108] The controller is configured to: when the first mode is running, when a preset sleep time point Ts1 is reached, control the first aromatherapy mechanism to run, and the aromatherapy concentration sensor detects the indoor aromatherapy concentration C in real time.

[0109] In the first time period after the preset sleep time point Ts1, when the indoor aromatherapy concentration C is higher than a preset sleep aromatherapy concentration Cs1, the new air module is controlled to run, and the new air module introduces outdoor fresh air into the room.

[0110] When the indoor aromatherapy concentration C is not higher than the preset sleep aromatherapy concentration Cs1, the new air module is stopped, and the first aromatherapy mechanism is controlled to run.

[0111] It can be provided that the first aromatherapy includes but is not limited to lavender, eucommia, sandalwood, bergamot and other aromatherapy beneficial to sleep.

[0112] The embodiment shortens the user's sleep time by releasing the first aromatherapy to help sleep in the first time period when the user needs to sleep. At the same time, when the aromatherapy concentration is too high in the first time period, the new air module is started to run to introduce fresh air into the room, thereby reducing the concentration of indoor aromatherapy, preventing the first aromatherapy concentration from being too high to affect the user's sleep quality, and ensuring the user's health.

[0113] In some embodiments, the air conditioner indoor unit is provided with a second aromatherapy mechanism, the second aromatherapy mechanism is arranged on the inner wall of the shell, and the second aromatherapy mechanism is arranged side by side with the first aromatherapy mechanism. The second aromatherapy mechanism contains second aromatherapy essential oil for releasing the second aromatherapy.

[0114] The controller is configured to: when the first time period is running and a preset wake-up time point Ts2 is reached, control the first aromatherapy mechanism to stop running, and control the second aromatherapy mechanism to run.

[0115] In the second time period after the preset wake-up time point Ts2, when the indoor aromatherapy concentration C is higher than a preset wake-up aromatherapy concentration Cs2, the new air module is controlled to run, and the new air module introduces outdoor fresh air into the room.

[0116] When the indoor aroma concentration C is not higher than the preset wake-up aroma concentration Cs2, the fresh air module is stopped, and the second aroma mechanism is controlled to be started.

[0117] It can be provided that the second aroma includes but is not limited to mint, lemon and other aromas that are beneficial to refreshing the mind.

[0118] The embodiment helps the user to wake up by releasing the second aroma to refresh the mind in the second time period when the user needs to wake up, and promotes the user to wake up from sleep. Meanwhile, when the aroma concentration in the second time period is too high, the fresh air module is started to introduce outdoor fresh air into the room, so as to reduce the indoor aroma concentration, and prevent the second aroma concentration from being too high to affect the user's health.

[0119] In some embodiments, the controller is configured to control the second aroma mechanism to stop running and control the fresh air module to be started when the wake-up time point is reached, and the fresh air module introduces outdoor fresh air into the room.

[0120] The second aroma released in the second time period has helped the user to wake up, and there is no need to release the aroma to help the user to wake up. At this time, the fresh air module is started to introduce outdoor fresh air into the room, to replace indoor and outdoor air, improve indoor air quality, and reduce the indoor aroma concentration C.

[0121] In some embodiments, the controller is configured to control the fresh air module to be stopped when the air conditioner indoor unit runs for a third time period to reach a preset stop time point after the wake-up time point is reached.

[0122] After the fresh air module is started for the third time period, the indoor and outdoor air is replaced by introducing outdoor fresh air, the indoor aroma concentration C is reduced, and the indoor air quality is improved.

[0123] In some embodiments, before the first mode is started, the user can pre-set the sleep time point and the wake-up time point in the first mode.

[0124] The controller is configured to define the preset sleep time point Ts1 as the n minutes before the sleep time point, and define the preset wake-up time point Ts2 as the m minutes before the wake-up time point, wherein n and m are positive numbers, and n > m.

[0125] The sleep time point and the wake-up time point are set by the user according to the user's sleep habits. After the first mode is started, the user will have n minutes of time to cultivate sleepiness. When the preset sleep time point Ts1 is reached, the controller controls the first aroma mechanism to be started to release the first aroma that is beneficial to sleep, so as to shorten the user's sleep time.

[0126] When the indoor incense concentration C is detected to be higher than the preset sleep incense concentration Cs1, that is, C > Cs1, it indicates that the indoor sleep incense concentration Cs1 is too high at this time, the controller controls to stop running the first incense mechanism and start running the fresh air module until the indoor incense concentration C is not higher than the preset sleep incense concentration Cs1, that is, C≤Cs1, the controller controls to close the fresh air module and start the first incense mechanism.

[0127] When running to the preset wake-up time point Ts2, the controller controls to stop running the first incense mechanism and start running the second incense mechanism to release the second incense to help the user wake up, and the user will have m minutes of time to wake up.

[0128] When the incense concentration sensor detects that the indoor incense concentration C is higher than the preset wake-up incense concentration Cs2, that is, C > Cs2, it is considered that the second incense concentration is too high, the controller controls to stop running the second incense mechanism and start running the fresh air module until the indoor incense concentration C is not higher than the preset wake-up incense concentration Cs2, that is, C≤Cs2, the controller controls to stop running the fresh air module.

[0129] When the running second time period reaches the wake-up time point Ts3, the second incense mechanism is controlled to stop running, and the fresh air module is controlled to start running, which introduces outdoor fresh air into the room to replace indoor and outdoor air and improve indoor air quality.

[0130] After reaching the wake-up time point, the air conditioner indoor unit runs for a third time period to reach a preset stop time point. When the preset stop time point Ts4 is reached, the fresh air module is controlled to stop running. After the fresh air module is continuously started for a third time period, the indoor and outdoor air are replaced by introducing outdoor fresh air, the indoor incense concentration C has been reduced, and the indoor air quality has been improved.

[0131] In some embodiments, the air conditioner indoor unit further comprises an indoor humidity sensor and a third incense mechanism. The indoor humidity sensor is arranged on the shell and is used to detect the indoor humidity in real time. The third incense mechanism is arranged in the body, the third incense mechanism contains a third incense essential oil, and the third incense mechanism is used to release the third incense.

[0132] The controller is configured to: when the indoor humidity φ is lower than the preset indoor humidity φ0 during the running of the second mode, the third incense mechanism is controlled to start running, and the third incense mechanism is controlled to stop running after running for a first preset time period.

[0133] During the first preset time period, when the indoor humidity is not lower than the preset indoor humidity, the third incense mechanism is controlled to stop running.

[0134] After the second mode is started, the indoor humidity φ is detected first. When the indoor humidity φ is lower than the preset indoor humidity φ0, the third fragrance mechanism is started to release the third fragrance. The third fragrance can include, but is not limited to, flower fragrance, grass fragrance, wood fragrance, fruit fragrance, etc. Otherwise, the third fragrance mechanism is not started.

[0135] When the third fragrance mechanism is stopped after the first preset time period Tb1, the indoor fragrance concentration C during the whole process is monitored during the first preset time period Tb1. If the indoor fragrance concentration C is higher than the preset third fragrance concentration Cb1, i.e., C > Cb1, the third fragrance mechanism is immediately stopped. Otherwise, the third fragrance mechanism is continuously started until the first preset time period Tb1 is completed, and then the third fragrance mechanism is stopped.

[0136] In some embodiments, the air conditioner indoor unit further includes an indoor humidity sensor and at least three fragrance mechanisms. The indoor humidity sensor is arranged on the shell and is used to detect the indoor humidity φ in real time. The plurality of fragrance mechanisms are arranged in the shell. The plurality of fragrance mechanisms are arranged side by side. Different fragrance oils are contained in the plurality of fragrance mechanisms. Different fragrance mechanisms release different fragrances.

[0137] Before the third mode is started, the user sets one or more fragrance mechanisms to be started in the third mode.

[0138] When the third mode is started, at least one of the fragrance mechanisms is started when the indoor humidity is lower than the preset indoor humidity.

[0139] When there are three fragrance mechanisms, the three fragrance mechanisms are respectively a first fragrance mechanism, a second fragrance mechanism, and a third fragrance mechanism.

[0140] The user can set the third mode to one of the following modes: only the first fragrance mechanism is started, only the second fragrance mechanism is started, only the third fragrance mechanism is started, the first fragrance mechanism and the second fragrance mechanism are started simultaneously, the first fragrance mechanism and the third fragrance mechanism are started simultaneously, the second fragrance mechanism and the third fragrance mechanism are started simultaneously, and the first fragrance mechanism, the second fragrance mechanism, and the third fragrance mechanism are started simultaneously.

[0141] Meanwhile, the user can set the running time of the first fragrance mechanism as Tz1, the running time of the second fragrance mechanism as Tz2, the running time of the third fragrance mechanism as Tz3, the running time of the first fragrance mechanism and the second fragrance mechanism as Tz4, the running time of the first fragrance mechanism and the third fragrance mechanism as Tz5, the running time of the second fragrance mechanism and the third fragrance mechanism as Tz6, and the running time of the first fragrance mechanism, the second fragrance mechanism, and the third fragrance mechanism as Tz7.

[0142] After the third mode is started, the indoor humidity is detected first, and when the indoor humidity is lower than the preset indoor humidity, the preset aromatherapy mechanism is started to release the aromatherapy spray, otherwise, no action is taken. In this embodiment, multiple aromatherapy sprays can be released simultaneously to achieve the effect of mixing the aromas.

[0143] When the corresponding cutoff time of the corresponding aromatherapy mechanism is reached, the controller controls the operation of the aromatherapy mechanism to stop, otherwise, the aromatherapy mechanism continues to operate to release the aromatherapy.
