[0002] After long-term use of existing air conditioners, problems such as dryness are likely to occur in the room. The vast majority of wall-mounted air conditioners do not have a humidifying function, which causes users to need to humidify through a humidifier to keep the room humidity in a suitable state.

[0003] The existing humidifying methods of air conditioners mainly include wet film humidification, steam humidification, and ultrasonic humidification, etc. Among them, steam humidification involves a relatively high cost of heating devices and is prone to damage to parts; ultrasonic humidifiers mainly make the water in the humidifier generate floating water mist through the high-frequency vibration of the atomizing sheet to achieve the purpose of air humidification; the key component in ultrasonic humidification is the atomizing sheet, which has a short designed service life and has certain requirements for water quality, not meeting the service life requirements of air conditioners. Wet film humidification uses the siphon effect to suck water to the surface of the wet film. Dry air is humidified after passing through the water-containing wet film and is sent to the room for humidification. Because the wet film is placed at the air inlet position, it will generate wind resistance and will also affect the refrigeration and heating performance to a certain extent.

[0047] Embodiment

[0048] <Overall layout>

[0049] As Figure 1a and 1b shown, the air conditioner provided in this embodiment has a first air inlet 131, a second air inlet 132, an air outlet 14, a fan 11, an evaporator 12, a controller, and a humidifying device. The first air inlet 131 and the second air inlet 132 are arranged on both sides of the upper part of the evaporator 12. The fan 11 is arranged below the evaporator 12. The air outlet 14 is arranged below the fan 11. The evaporator 12 includes a left evaporator 121 and a right evaporator 122, which are respectively arranged on the left and right sides of the upper part of the fan 11. Under the action of the fan 11, indoor air enters the air conditioner 1 from the first air inlet 131 and the second air inlet 132 respectively, completes heat exchange with the evaporator 12, and is discharged into the room from the air outlet 14. The humidifying device includes a wet film assembly 2, a water supply mechanism, and a detection module. The wet film assembly 2 has a wet film and a driving mechanism, and the driving mechanism drives the wet film to move. The water supply mechanism has a pump body, a water tank, and a nozzle. Under the action of the pump body, the condensate in the water tank is sprayed out by the nozzle and wets the surface of the wet film. The detection module is used to detect the indoor humidity.

[0050] The controller is electrically connected to the fan 11, the driving mechanism, the pump body, and the detection module respectively, and is used to receive the data transmitted by the detection module and control the operation of the driving mechanism, the pump body, and the fan 11 to make the indoor humidity reach the preset humidity.

[0051] <Humidifying device>

[0052] As Figure 2a and 2b shown, the wet film assembly 2 provided in this embodiment also has a wet film holder. The wet film is detachably connected to the wet film holder, facilitating the replacement of the wet film. Specifically, the driving mechanism is a gear-rack mechanism and a motor, including a gear and a rack. The gear is drivingly connected to the motor, and the rack is detachably connected to the wet film holder. Under the action of the motor, the gear meshes with the rack, driving the wet film holder to move, and thus the wet film to act.

[0053] Preferably, the wet film assembly has a first wet film assembly 21 and a second wet film assembly 22; the first wet film assembly 21 and the second wet film assembly 22 are respectively arranged on the left side and the right side of the air conditioner 1.

[0054] Preferably, the first wet film assembly 21 and the second wet film assembly 22 have the same structure. Taking the second wet film assembly 22 as an example, the main surface of the second wet film rack 221 is arranged in parallel with the main body of the right evaporator 122, and the condensed water sprayed onto the surface of the right wet film gradually diffuses to the entire right wet film under the action of gravity.

[0055] The width of the main surface of the right evaporator 122 corresponds to the width of the second wet film rack 221, and the length of the main surface of the right evaporator 122 corresponds to the length of the second wet film rack 221. When the right wet film is arranged on the second wet film rack 221, along the width direction of the main surface of the right evaporator 122, the right wet film covers the main surface of the right evaporator 122 with a large area and contacts the air, enabling water to be quickly converted into water vapor; along the length direction of the main surface of the right evaporator 122, the contact surface between the right wet film and the air is large, making the humidifying effect on the air entering the air conditioner obvious.

[0056] Preferably, the wet film rack has a first preset position and a second preset position; when the wet film rack is in the first preset position 231, the wet film faces the air inlet of the air conditioner and corresponds to the position of the nozzle, enabling the water on the surface of the wet film to fully contact the air; when the wet film rack is in the second preset position 232, the wet film is away from the air inlet of the air conditioner to ensure the air intake of the air conditioner.

[0057] Specifically, along the length direction of the main surface of the right evaporator 122, the first preset position 231 of the first wet film rack 211 is close to the middle of the right evaporator 122. At this time, the position of the first wet film rack 211 corresponds to the position of the first nozzle 311, the first wet film rack 211 faces the first air inlet 131, and the second preset position 232 of the first wet film rack 211 is close to the left side of the right evaporator 122. At this time, the first wet film rack 211 is away from the first air inlet 131; along the length direction of the main surface of the right evaporator 122, the first preset position 231 of the second wet film rack 221 is close to the middle of the right evaporator 122. At this time, the position of the second wet film rack 221 corresponds to the position of the second nozzle 312, the second wet film rack 221 faces the second air inlet 132, and at this time, the second wet film rack 221 is away from the second air inlet 132.

[0058] It should be noted that the number and specific positions of the preset positions of the wet film rack are not limited. According to the actual situation, multiple preset positions can be set to meet the air intake and humidifying effects.

[0059] Preferably, when the air conditioner 1 is in the humidification mode, the wet film holder moves to the first preset position 231 under the action of the gear-rack mechanism, and the water on the surface of the wet film is mixed with the air entering the air conditioner; when the air conditioner 1 is in the air supply and / or refrigeration and / or heating mode, the wet film holder moves to the second preset position 232 under the action of the gear-rack mechanism, and the water on the surface of the wet film can be evaporated by the air flowing in the air conditioner, reducing the influence of the wet film on the refrigeration and heating performance of the air conditioner.

[0060] Specifically, when the air conditioner is in the humidification mode, the first wet film holder 211 moves from the left side of the left evaporator 121 to the middle of the left evaporator 121 under the action of the first gear-rack mechanism; the second wet film holder 221 moves from the right side of the right evaporator 122 to the middle of the right evaporator 122 under the action of the second gear-rack mechanism; under the action of the pump body, the condensed water in the water tank is respectively ejected from the first nozzle 311 and the second nozzle 312 and sprayed onto the corresponding wet film, and the wet film is wetted.

[0061] When the air conditioner is in the air supply and / or refrigeration and / or heating mode, the first wet film holder 211 moves from the middle of the left evaporator 121 to the left side of the left evaporator 121 under the action of the first gear-rack mechanism; the second wet film holder 221 moves from the middle of the right evaporator 122 to the right side of the right evaporator 122 under the action of the second gear-rack mechanism; the water on the surface of the wet film is evaporated by the air flowing in the air conditioner, preventing the wet film from being in a wet state for a long time and breeding bacteria.

[0062] <Control part>

[0063] The pump body provided in this embodiment has a first power and a second power. When the pump body operates at the first power, the amount of water ejected by the nozzle is less than the amount of water ejected by the nozzle when the pump body operates at the first power.

[0064] It should be noted that the power number of the pump body is not limited, and multiple power numbers can be set according to actual situations. For example, the pump body can be made to operate at different powers by controlling the power supply voltage.

[0065] Furthermore, when different amounts of water are sprayed onto the wet film, the wetting effect of the wet film is different, and the wet film has different degrees of humidity. The different degrees of humidity of the wet film can be achieved by controlling the operating power and operating time of the pump body.

[0066] The wet film provided in this embodiment has a first degree of humidity and a second degree of humidity; when the wet film is at the first degree of humidity, the amount of water attached to the surface of the wet film is small, the contact surface with the air is small, and the moisture content in the air after mixing is low, which is suitable when the indoor humidity is close to the preset humidity; when the wet film is at the second degree of humidity, the amount of water attached to the surface of the wet film is large, the contact surface with the air is large, and the moisture content in the air after mixing is high, and the humidification effect is obvious, which is suitable when the indoor humidity is far from the preset humidity.

[0067] Preferably, the detection module is provided with a humidity sensor which detects the indoor humidity H1 and transmits the detection data to the controller. The controller determines whether H0 is less than a first preset humidity H1. When the indoor humidity H0 is less than the first preset humidity H1, the controller controls the air conditioner to enter the humidification mode.

[0068] Specifically, when the indoor humidity H0 is less than the first preset humidity H1 and greater than a second preset humidity H1, the controller controls the pump body to operate at a first power and starts timing. The condensed water in the water tank is sprayed onto the wet film by the nozzle in a small flow rate and adheres to the surface of the wet film. When the timing time T0 is greater than a first preset time T1, the controller controls the pump body to stop.

[0069] When the indoor humidity H0 is less than the second preset humidity H2, the controller controls the pump body to operate at a second power and starts timing. The condensed water in the water tank is sprayed onto the wet film by the nozzle in a large flow rate and adheres to the surface of the wet film. When the timing time T0 is greater than a second preset time T2, the controller controls the pump body to stop.

[0070] Preferably, the first preset humidity H1 is 50% of the moisture content of the indoor air, and the second preset humidity H2 is 40% of the moisture content of the indoor air; the first preset time T1 is 10 s; the second preset time T2 is 15 s; when the power supply voltage of the pump body is 15 V, the pump body operates at the first power; when the power supply voltage of the pump body is 24 V, the pump body operates at the second power.

[0071] <Control method>

[0077] S5. The controller controls the fan to operate, and the indoor air enters the air conditioner from the air inlet of the air conditioner, mixes with the water on the wet film, is converted into water vapor, and is discharged into the room from the air outlet of the air conditioner.

[0078] Preferably, the controller described in step S4 controls the operation of the pump body, and the condensed water in the water tank is sprayed from the nozzle onto the wet film and adheres to the surface of the wet film, including:

[0079] S41. When the indoor humidity H0 is less than the first preset humidity H1 and greater than the second preset humidity H1, the controller controls the operation of the pump body and starts timing.
