DETAILED DESCRIPTION

[0033] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0034] like Figure 1 and Figure 6 As shown, an air conditioner indoor unit 1 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0035] An air-conditioning indoor unit 1 according to an embodiment of the present invention includes a housing 10 and a humidifying mechanism 20 .

[0036] Specifically, the shell 10 defines a first air duct, an air inlet and an air outlet. The first air duct is connected to the air inlet and the air outlet at the same time. A fan is provided in the first air duct. A drain pipe is also provided in the shell 10. A movable air guide plate is also provided on the shell 10, and the air guide plate can avoid or close the air outlet; the humidifying mechanism 20 includes a mist outlet, and the mist outlet is connected to the air outlet through the second air duct. The humidifying mechanism 20 includes a first liquid storage bottle 21 and a second liquid storage bottle 22. The first liquid storage bottle 21 is connected to the second liquid storage bottle 22, and the second liquid storage bottle 22 is connected to the drain pipe.

[0037] In detail, the fan is configured to drive the airflow to enter the first air duct, exchange heat, and then be blown out through the air outlet. The drain pipe is in communication with the second liquid storage bottle 22, and can be configured to drain all the condensed water generated by the air conditioner indoor unit 1 into the second liquid storage bottle 22, or can be configured to drain part of the condensed water generated by the air conditioner indoor unit 1 outside, and drain part of the condensed water into the second liquid storage bottle 22. The first liquid storage bottle 21 can be configured to store sterilization and fragrance liquid, and the condensed water can be used as the liquid supplement of the second liquid storage tank, so that water does not need to be added to the second liquid storage tank. The liquid in the second liquid storage tank is mixed with the liquid in the first liquid storage bottle 21, sprayed out through the mist outlet, and finally enters the first air duct through the second air duct, mixed with the gas, and blown out of the air outlet by the fan, so that the air conditioner indoor unit 1 finally blows out the humidified and fragrant cold air, and the air humidity in the room where the air conditioner indoor unit 1 is located is maintained in a range comfortable for human body, and the user's use comfort is improved.

[0038] It should be noted that various solutions beneficial to human body can be added to the first liquid storage bottle 21 according to user's needs, and the present application is not limited.

[0039] In some embodiments, the second liquid storage bottle 22 includes a bottle body 23 and a bottle cap 24 arranged on the bottle body 23, so that the bottle cap 24 is convenient for disconnection and periodic cleaning of the inside of the bottle body 23.

[0040] According to the air conditioner indoor unit 1 of the embodiment of the present application, the condensed water drained by the drain pipe can be recycled, the condensed water is drained into the second liquid storage bottle 22, and the sterilization and freshening liquid in the first liquid storage bottle 21 is mixed to humidify and deodorize the indoor air, so as to alleviate the odor generated by the air conditioner indoor unit 1.

[0041] According to the air conditioner indoor unit 1 of the embodiment of the present application, the humidification mechanism 20 includes an atomizer, the atomizer defines a mist outlet, and the other end of the atomizer is in communication with the second liquid storage bottle 22. By arranging the atomizer, the mixed liquid in the first liquid storage bottle 21 can be finally atomized into water mist and enter the first air duct through the second air duct. In some embodiments, the atomizer can be configured as an ultrasonic atomizer, which can save energy. At the same time, a large amount of negative ions are released during the atomization process, which can produce electrostatic reactions with smoke, dust and other substances floating in the air, so as to precipitate the substances, effectively remove harmful substances such as formaldehyde, carbon monoxide and bacteria, purify the air, and reduce the occurrence of diseases.

[0042] As Figure 1 , Figure 2 and Figure 6As shown, in some embodiments, the second liquid storage bottle 22 comprises a first inlet 221, a second inlet 222 and a first outlet 223, the first inlet 221 and the second inlet 222 are arranged at the top of the second liquid storage bottle 22, and the first outlet 223 is arranged at the bottom of the second liquid storage bottle 22, the first inlet 221 is communicated with the drain pipe through a first liquid inlet pipe, the second inlet 222 is communicated with the first liquid storage bottle 21, and the first outlet 223 is communicated with the atomizer. The first inlet 221 and the second inlet 222 are arranged at the top of the second liquid storage bottle 22, which facilitates the condensate water to enter the second liquid storage bottle 22 by gravity, and facilitates the sterilization and fragrance enhancing liquid in the first liquid storage bottle 21 to enter the second liquid storage bottle 22 by gravity. By arranging the first outlet 223 at the bottom of the second liquid storage bottle 22, the mixed liquid in the second liquid storage bottle 22 can be discharged from the first outlet 223 into the atomizer for atomization by gravity, thereby simplifying the components and achieving the effect of simplifying the structure.

[0043] In some embodiments, the second liquid storage bottle 22 is divided into a first chamber and a second chamber, and the second liquid storage bottle 22 is further provided with a third inlet and a second outlet, the first inlet 221, the second inlet 222, the first outlet 223 and the second outlet are all communicated with the first chamber, the second outlet is communicated with the drain pipe through a liquid discharge pipe, the second outlet is closable, the drain pipe is communicated with the second chamber in sequence through a second liquid inlet pipe and the third inlet, a first switch valve is arranged on the second liquid inlet pipe, a gas pump and a pressure spray head connected with the gas pump are arranged in the second chamber, and the second chamber is communicated with the first chamber through the pressure spray head. As the use time is prolonged, in order to prevent bacteria from being generated in the first chamber, the first switch valve can be controlled to be opened, so that the water in the drain pipe can enter the second chamber, and the gas pump is used to suck and pressurize to spray into the first chamber through the pressure spray head for cleaning, thereby improving the cleanliness of the first chamber, preventing bacteria from breeding in the first chamber, and the waste liquid after cleaning the first chamber can be discharged through the second outlet. When the waste liquid does not need to be discharged, the second outlet can be kept closed.

[0044] In some embodiments, a first filter screen is arranged at each of the first inlet 221, the second inlet 222 and the third inlet, and / or a second filter screen is arranged at the first outlet 223.

[0045] That is, in some embodiments, a first filter screen is arranged at each of the first inlet 221, the second inlet 222 and the third inlet, so that the liquid entering the first chamber and the second chamber can be filtered to prevent impurities from entering the first chamber and the second chamber.

[0046] In some embodiments, a first filter is provided at the first inlet 221, the second inlet 222 and the third inlet, and a second filter is provided at the first outlet 223, so that the liquid entering the atomizer can be further filtered by the second filter, thereby preventing impurities from entering the atomizer.

[0047] In some embodiments, a humidity sensor is further provided in the air inlet, and the indoor air humidity is detected by the humidity sensor. When the humidity sensor detects that the indoor air humidity is lower than a first preset humidity value, it indicates that the indoor air is relatively dry, and the humidification mechanism 20 is controlled to turn on. When the humidity sensor detects that the indoor air humidity is higher than a second preset humidity value, it indicates that the indoor air humidity is high, and the humidification mechanism 20 is controlled to stop humidification to prevent the indoor air humidity from being too high, which may be counterproductive.

[0048] like Figures 1-5 As shown, according to an embodiment of the present invention, the air conditioner indoor unit 1 has a housing 10 comprising a bottom housing, an inner housing 12, a panel body, and two side panels 13. The inner housing 12 is mounted on the bottom housing and forms a housing space therewith. One side panel 13, the panel body, and the other side panel 13 are sequentially connected and mounted outside the housing space. The humidifying mechanism 20 is detachably disposed between the side panel 13 and the inner housing 12. This eliminates the need for additional cover panels to cover the structure within the inner housing 12 of the air conditioner indoor unit 1, and production line upgrades and modifications are minimal. Only structural changes between the side panels 13 and the inner housing 12 are required to install the humidifying mechanism 20.

[0049] like Figures 1-5 As shown, in some embodiments, the side panel 13 is detachably connected to the inner shell 12, a first snap-fit ​​structure 224 and a second snap-fit ​​structure 225 are provided on the outer wall of the second liquid storage bottle 22, a third snap-fit ​​structure 131 is provided on the side panel 13, and a fourth snap-fit ​​structure 121 is provided on the inner shell 12, the first snap-fit ​​structure 224 and the third snap-fit ​​structure 131 are snapped together, and the second snap-fit ​​structure 225 and the fourth snap-fit ​​structure 121 are snapped together.

[0050] like Figures 1-5 As shown, in some embodiments, one of the first snap-fit ​​structure 224 and the third snap-fit ​​structure 131 is configured as a limiting column 2241, and the other is configured as a limiting hole 132, and one of the second snap-fit ​​structure 225 and the fourth snap-fit ​​structure 121 is configured as a groove 2251, and the other is configured as a protrusion 1211.

[0051] In some embodiments, the first liquid storage bottle 21 and the second liquid storage bottle 22 are detachably connected. This facilitates the installation of the first liquid storage bottle 21 on the second liquid storage bottle 22. After transporting and installing them to the corresponding positions, the side panel 13 can be disassembled to install the first liquid storage bottle 21 on the second liquid storage bottle 22. When the sterilizing and refreshing liquid in the first liquid storage bottle 21 is used up, it can be easily replaced.

[0052] In some embodiments, the first liquid storage bottle 21 and the second liquid storage bottle 22 are connected via a quick-release connector 226 , and the second inlet 222 of the first liquid storage bottle 21 can be blocked by bolts during transportation and delivery.

[0053] In some embodiments, a bottle opener is provided on the second liquid storage bottle 22, and the liquid outlet of the first liquid storage bottle 21 is sealed by sealing paper. As the first liquid storage bottle 21 is gradually rotated and installed on the second liquid storage bottle 22, the bottle opener can pierce the sealing paper, so that the liquid in the first liquid storage bottle 21 flows into the second liquid storage bottle 22 along the bottle opener.

[0054] According to the air conditioner indoor unit 1 of the embodiment of the present invention, a sterilization module is provided in the second liquid storage bottle 22 .

[0055] According to the air conditioner indoor unit 1 of the embodiment of the present invention, the liquid in the second liquid storage bottle 22 can be sterilized by the sterilization module, thereby enhancing the cleanliness of the aerosol sprayed by the atomizer.

[0056] like Figure 7 As shown, the control method according to an embodiment of the present invention is used to control the above-mentioned air-conditioning indoor unit 1, including:

[0057] S11: Turn on the fan;

[0058] S12: Detecting the air humidity and obtaining the air humidity value, and controlling the humidification mechanism 20 to be turned on or off according to the air humidity value.

[0059] According to the control method of an embodiment of the present invention, the air humidity in the room where the air-conditioning indoor unit 1 is located can be obtained through the humidity sensor, and the indoor air is humidified and deodorized according to the detected humidity value to ensure that the air humidity in the air-conditioning room is maintained in a range that is comfortable for the human body, thereby improving the user's comfort.

[0060] For example, when the humidity sensor detects that the indoor air humidity is lower than the first preset humidity value, it means that the indoor air is relatively dry, and the humidification mechanism 20 is controlled to turn on. When the humidity sensor detects that the indoor air humidity is higher than the second preset humidity value, it means that the indoor air humidity is high, and the humidification mechanism 20 is controlled to stop humidification to prevent the indoor air humidity from being too high, which would be counterproductive.

[0061] After the air conditioner is used for a period of time, when the air conditioner is started, a peculiar smell is emitted. This situation is due to the fact that the evaporator and other components in the air conditioner indoor unit are not completely dried after operation, and a large amount of dust, bacteria, mold and mites and other microorganisms accumulate in the air conditioner indoor unit over a long period of time. Therefore, when the air conditioner is started again, the air conditioner indoor unit blows out a large amount of microorganisms, resulting in the emergence of a peculiar smell, and the peculiar smell weakens or disappears after a period of time. Even if the peculiar smell is not smelled in the room when the air conditioner is started, the microorganisms in the room are inhaled into the lungs of the user, which can cause great harm to the health of the user.

[0062] As shown in Figure 8 Therefore, in some embodiments, the control method further comprises:

[0063] S21: control the air outlet to be closed, and start the fan and the humidifying mechanism 20;

[0064] S22: after the humidifying mechanism 20 operates for a first preset time, the humidifying mechanism 20 is closed;

[0065] S23: control the fan to continue to operate for a second preset time, and then close the fan.

[0066] According to the control method of the embodiment of the application, the air outlet is closed by the air deflector, so that the air conditioner indoor unit 1 forms a relatively closed cavity. At the same time, the fan and the humidifying mechanism 20 are started, so that the mixed gas mist flows in the air conditioner indoor unit 1 along with the operation of the fan, thereby being able to flush other structures of the air conditioner indoor unit 1, and effectively flushing the dust, mold and mites and other microorganisms from the above-mentioned parts and cleaning the parts. After the humidifying mechanism 20 is closed, the fan is controlled to continue to operate for a second preset time, and then the fan is closed. The fan can continue to operate to dry other parts, so that the inside of the air conditioner indoor unit 1 is in a dry state as much as possible, which is beneficial to prolong the service life of the air conditioner indoor unit 1.
