Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a humidification control method for an air conditioner and an air conditioner. Background Technology

[0002] When the ambient air is dry, the air conditioner will accelerate indoor air circulation, making the indoor air even drier and causing discomfort to users. Some existing air conditioners add a humidification module to the indoor unit to enable humidification. However, the humidification control in existing air conditioners is based solely on the indoor humidity level and cannot achieve precise control. Summary of the Invention

[0003] One object of the present invention is to provide a humidification control method for an air conditioner with more precise humidification control.

[0004] Specifically, the present invention provides a humidification control method for an air conditioner, wherein the indoor unit of the air conditioner is provided with a humidification box and a blower, the humidification box including a box body for holding water and a box cover movably disposed at the opening of the box body, wherein the method includes:

[0005] When the air conditioner turns on the humidification function, obtain the operating mode of the air conditioner;

[0006] Get the fan speed setting;

[0007] Adjust the opening of the lid based on the operating mode and fan speed setting.

[0008] Optionally, the operating mode includes an on / off cooling mode and a non-on cooling mode; based on the operating mode and fan speed setting, the steps for adjusting the opening of the lid include:

[0009] When the operating mode is set to cooling mode, check whether the fan speed is not higher than the first preset low speed.

[0010] If so, close the control box lid completely.

[0011] Optionally, after the step of fully closing the control box cover, the method further includes: controlling the speed of the air supply fan so that the fan speed is higher than the first preset low speed.

[0012] Optionally, when the operating mode is cooling mode and the fan speed is higher than the first preset low setting, the method includes:

[0013] The opening degree of the box lid corresponding to the wind speed level is determined according to the preset first mapping relationship. The first mapping relationship specifies the opening degree of the box lid corresponding to different wind speed levels. In the first mapping relationship, as the wind speed level increases, the opening degree of the box lid decreases.

[0014] Optionally, when the operating mode is non-cooling mode, determine whether the fan speed is not higher than the second preset low speed.

[0015] If so, the control box cover is fully open, with the second preset low setting higher than the first preset low setting.

[0016] Optionally, when the operating mode is non-cooling mode and the fan speed is higher than the second preset low speed, the method includes:

[0017] The opening degree of the box lid corresponding to the wind speed level is determined according to the preset second mapping relationship. The second mapping relationship specifies the opening degree of the box lid corresponding to different wind speed levels. In the second mapping relationship, as the wind speed level increases, the opening degree of the box lid decreases.

[0018] Optionally, when the air conditioner is in cooling mode, heating mode, ventilation mode, or sleep mode, the method further includes:

[0019] When a user's command to activate the humidification function is received, the indoor air humidity value is obtained;

[0020] Determine the relationship between the indoor air humidity value and the first preset humidity threshold and the second preset humidity threshold, wherein the second preset humidity threshold is greater than the first preset humidity threshold;

[0021] When the indoor air humidity is lower than the first preset humidity threshold, the air conditioner is controlled to start humidifying.

[0022] When the indoor air humidity value is greater than the first preset humidity threshold and less than or equal to the second preset humidity threshold, the air conditioner is controlled to issue a first prompt message and a first inquiry message. The first prompt message is used to remind the user that the humidity is appropriate, and the first inquiry message is used to ask whether to continue to turn on the humidification function. When the user's instruction to continue to turn on the humidification function is received, the air conditioner is controlled to start humidification. When the user's instruction to continue to turn on the humidification function is not received, the air conditioner is controlled to cancel the humidification function.

[0023] When the indoor air humidity value exceeds the second preset humidity threshold, the air conditioner is controlled to issue a second prompt message and a first inquiry message. The second prompt message is used to remind the user that the humidity is too high, and the first inquiry message is used to ask whether to continue to turn on the humidification function. When the user's instruction to continue to turn on the humidification function is received, the air conditioner is controlled to start humidification. When the user's instruction to continue to turn on the humidification function is not received, the air conditioner is controlled to cancel the humidification function.

[0024] Optionally, when the air conditioner is in humidification mode, the method further includes:

[0025] Obtain indoor air humidity values;

[0026] Determine the relationship between the indoor air humidity value and the first preset humidity threshold and the second preset humidity threshold, wherein the second preset humidity threshold is greater than the first preset humidity threshold;

[0027] When the indoor air humidity is lower than the first preset humidity threshold, the air conditioner will continue to humidify.

[0028] When the indoor air humidity value is greater than the first preset humidity threshold and less than or equal to the second preset humidity threshold, the air conditioner is controlled to issue a first prompt message and a second inquiry message. The first prompt message is used to remind the user that the humidity is appropriate, and the second inquiry message is used to ask whether to continue humidifying. When the user's instruction to continue humidifying is received, the air conditioner is controlled to continue humidifying. When the user's instruction to continue humidifying is not received, the air conditioner is controlled to turn off.

[0029] When the indoor air humidity value exceeds the second preset humidity threshold, the air conditioner is controlled to issue a second prompt message and a second inquiry message. The second prompt message is used to remind the user that the humidity is too high, and the second inquiry message is used to ask whether to continue humidifying. When the user's instruction to continue humidifying is received, the air conditioner is controlled to continue humidifying. When the user's instruction to continue humidifying is not received, the air conditioner is controlled to turn off.

[0030] Optionally, a water level detection device is installed inside the humidifier box, and the method further includes:

[0031] Get the water level in the humidifier box;

[0032] Determine whether the water volume value is not greater than the preset minimum water volume threshold;

[0033] If so, determine the operating status of the air conditioner, which includes humidification-only mode, humidification-addition mode, and no humidification mode;

[0034] When the air conditioner is in humidification mode only, control the air conditioner to issue a water filling prompt and turn off the machine;

[0035] When the air conditioner is in auxiliary humidification mode, the control unit will issue a water filling prompt and stop humidification.

[0036] When the air conditioner is not humidifying, it will issue a water replenishment reminder when the air conditioner is turned off.

[0037] The present invention also provides an air conditioner, comprising:

[0038] The indoor unit has an air outlet on its casing;

[0039] The air supply fan is installed inside the casing and is used to draw indoor air into the indoor unit and blow it out of the casing through the air outlet.

[0040] A humidifier box, housed within the casing, includes a water-holding body and a lid movably disposed at an opening in the body; and

[0041] The control device includes a controller and a memory, the memory storing a machine-executable program, and when the machine-executable program is run, the controller performs the aforementioned humidification control method.

[0042] The humidification control method of the present invention for an air conditioner includes a humidification box in the indoor unit, comprising a box for holding water and a box cover movably disposed at the opening of the box. When the air conditioner turns on the humidification function, the operating mode of the air conditioner and the fan speed are obtained, and the opening of the box cover is adjusted based on the operating mode and fan speed, so that the humidification control is more precise and the humidification effect is better.

[0043] Furthermore, the humidification control method of the air conditioner of the present invention determines whether the fan speed is not higher than the first preset low speed when the operating mode is the cooling mode, and controls the cover to be fully closed when the fan speed is not higher than the first preset low speed, so as to avoid water molecules in the air from forming condensation and causing the air to be dry when the fan speed is low.

[0055] Figure 1 This is a perspective view of an air conditioner 100 according to an embodiment of the present invention. Figure 2 yes Figure 1 A magnified view of a portion of the image. Figure 3 yes Figure 1 A partially enlarged schematic diagram of the humidifier box 200 of the air conditioner 100 shown. Figure 4 yes Figure 1 The diagram shows the component configuration of the air conditioner 100. Figure 5 yes Figure 1 A flowchart illustrating the humidification control method of the air conditioner 100 shown.

[0056] like Figure 1 and Figure 2 As shown, the air conditioner 100 of this embodiment includes: an indoor unit, a blower 103, and a humidifier box 200. An air outlet 102 is provided on the casing 101 of the indoor unit. The blower 103 is disposed inside the casing 101 and is used to induce indoor air to enter the indoor unit and be blown out of the casing 101 through the air outlet 102. The humidifier box 200 is disposed inside the casing 101 and includes a water-filled box body 201 and a cover 202 movably disposed at the opening of the box body 201. The humidification control method of the air conditioner 100 of this embodiment includes the following steps:

[0057] S102: When the humidification function of the air conditioner 100 is turned on, obtain the operating mode of the air conditioner 100;

[0058] S104: Obtain the wind speed setting of the blower 103;

[0059] S106: Adjust the opening degree of the box cover 202 based on the operating mode and fan speed setting.

[0060] The humidification control method of the air conditioner 100 in this embodiment of the invention provides a humidification box 200 in the indoor unit, which includes a water-filled box 201 and a box cover 202 movably disposed at the opening of the box 201. When the air conditioner 100 turns on the humidification function, the operating mode of the air conditioner 100 and the fan speed of the blower 103 are obtained. The opening of the box cover 202 is adjusted based on the operating mode and the fan speed, so that the humidification control is more precise and the humidification effect is better.

[0061] The air conditioner 100 of this embodiment of the invention further includes a control device 300, including a controller 301 and a memory 302. The memory 302 stores a machine-executable program 320, and when the machine-executable program 320 is run, the controller 301 executes the aforementioned humidification control method.

[0062] like Figure 1 As shown, the indoor unit of the air conditioner 100 in this embodiment of the invention is a wall-mounted air conditioner indoor unit. Its casing 101 has a horizontally extending elongated air outlet 102 on the lower front side, and an air inlet (not shown in the figure) on the top. The air supply fan 103 is a cross-flow fan, extending horizontally. Figure 4 As shown, the air conditioner 100 also includes: a heat exchanger 106, a fresh air fan 104, and a dehumidification module 105. The heat exchanger 106 is used to exchange heat with the air entering the casing 101 through the air inlet, forming a heat exchange airflow. The heat exchange airflow flows out from the air outlet 102. The fresh air fan 104 is located to the left of the cross-flow fan and is used to draw outdoor air into the indoor unit. The inlet of the fresh air fan 104 is connected to the outdoor environment via a fresh air duct, and the outlet is connected to a fresh air outlet (not shown in the figure) located at the top of the casing 101. The dehumidification module 105 is used to remove and absorb moisture. The humidification box 200 is elongated and located inside the casing 101 near the air outlet 102, with its opening generally facing upwards. Figure 3 As shown, the humidifier box 200 includes a box body 201, a box lid 202, and a drive mechanism 203. The drive mechanism 203 includes a gear 231, a rack 232, and a motor 233. The rack 232 is provided on the lower surface of the box lid 202. The motor 233 is fixed to the box body 201, and its output shaft is connected to the gear 231. The gear 231 meshes with the rack 232. The motor 233 drives the gear 231 to rotate, which in turn moves the rack 232 and the box lid 202, thereby adjusting the opening degree of the box lid 202. Two sliding ribs 210 are formed at the left and right ends of the upper part of the box body 201, and two corresponding sliding grooves 220 are formed on the box lid 202. The sliding ribs 210 fit into the sliding grooves 220, so as to guide the movement of the box lid 202.

[0063] The air conditioner 100 of this embodiment of the invention includes an on-cooling mode and a non-on cooling mode. For example... Figure 6As shown, the humidification control method of the air conditioner 100 according to an embodiment of the present invention includes the following steps:

[0064] S202: When the humidification function of the air conditioner 100 is turned on, obtain the operating mode of the air conditioner 100. When the operating mode is the cooling mode, execute step S204; when the operating mode is the non-cooling mode, execute step S210.

[0065] S204: Determine whether the wind speed setting is not higher than the first preset low setting. If the result of step S204 is yes, proceed to step S206; if the result of step S204 is no, proceed to step S208.

[0066] S206: Control box cover 202 fully closed.

[0067] S208: Determine the opening degree of the cover 202 corresponding to the wind speed level according to the preset first mapping relationship. The first mapping relationship specifies the opening degree of the cover 202 corresponding to different wind speed levels. In the first mapping relationship, as the wind speed level increases, the opening degree of the cover 202 decreases.

[0068] S210: Determine whether the wind speed setting is not higher than the second preset low setting, where the second preset low setting is higher than the first preset low setting. If the result of step S210 is yes, proceed to step S212; if the result of step S210 is no, proceed to step S214.

[0069] S212: Control box cover 202 fully open.

[0070] S214: Determine the opening degree of the cover 202 corresponding to the wind speed level according to the preset second mapping relationship. The second mapping relationship specifies the opening degree of the cover 202 corresponding to different wind speed levels. In the second mapping relationship, as the wind speed level increases, the opening degree of the cover 202 decreases.

[0071] When the air conditioner 100 is in humidification mode, during the cooling process of the air conditioner 100, the airflow velocity through the outlet of the humidification box 200 is directly proportional to the evaporation rate of the humidifying water, while the airflow velocity through the heat exchanger 106 is inversely proportional to the condensate outflow rate. That is, when the airflow speed is below a certain level, water molecules in the air will condense, causing the air to become dry; when the airflow speed is above a certain level, the humidification effect is more pronounced. However, when the air conditioner 100 is not in cooling mode, the airflow through the heat exchanger 106 will not condense. The humidification control method of the air conditioner 100 in this embodiment of the invention determines whether the fan speed is not higher than a first preset low level when the operating mode is cooling mode. If the fan speed is not higher than the first preset low level, the box cover 202 is fully closed to avoid humidification when the fan speed is too low.

[0072] After the control box cover 202 is fully closed in step S206, the method further includes: controlling the speed of the air supply fan 103 to adjust the speed level to be higher than the first preset low level. Then, step S208 can be executed. Simultaneously, to minimize the impact of wind feel caused by changes in the air supply fan 103's speed, it is preferable to increase the air supply fan 103's speed level to slightly higher than the first preset low level.

[0073] The air conditioner 100 of this embodiment can have the following operating modes: automatic mode, cooling mode, heating mode, ventilation mode, humidification mode, dehumidification mode, fresh air exchange mode, and sleep mode, to meet different user needs. The automatic mode can be further divided into automatic cooling mode and automatic heating mode, and the sleep mode can be further divided into sleep cooling mode and sleep heating mode. In this embodiment, when the air conditioner 100 is in fresh air exchange mode or dehumidification mode, the humidification function cannot be activated. Thus, cooling mode, automatic cooling mode, and sleep cooling mode are considered active cooling modes, while heating mode, ventilation mode, humidification mode, automatic heating mode, and sleep heating mode are considered inactive cooling modes.

[0074] Assume that the blower 103 typically has 7 speed settings, each with a corresponding speed range. Settings 1 and 2 are low speed settings, 3, 4, and 5 are medium speed settings, and 6 and 7 are high speed settings. Assume the humidifier box 200's lid 202 has 6 opening positions: fully open, 4 / 5 open, 3 / 5 open, 2 / 5 open, 1 / 5 open, and fully closed. The first preset low speed setting is, for example, setting 2, and the second preset low speed setting is, for example, setting 3. In this mapping, setting 3 corresponds to a fully open lid 202, setting 4 to a 4 / 5 open lid 202, setting 5 to a 3 / 5 open lid 202, setting 6 to a 2 / 5 open lid 202, and setting 7 to a 1 / 5 open lid 202. That is, as the speed setting increases, the opening of the lid 202 decreases. In the second mapping relationship, the opening degree of the lid 202 is 4 / 5 open for speed 4, 3 / 5 open for speed 5, 2 / 5 open for speed 6, and 1 / 5 open for speed 7. That is, as the fan speed increases, the opening degree of the lid 202 decreases. In both the first and second mapping relationships, the opening degree of the lid 202 can be the same for high-speed and medium-speed speeds, because the operating mode has little impact on the humidification effect at this point.

[0075] Thus, when the air conditioner 100 is in cooling mode and the fan speed is at level 1, which is lower than the first preset low level of 2, the control cover 202 is fully closed. When the air conditioner 100 is in cooling mode and the fan speed is at level 2, which is equal to the first preset low level of 2, the control cover 202 is also fully closed. When the air conditioner 100 is in cooling mode and the fan speed is at level 3, which is higher than the first preset low level of 2, according to the first mapping relationship, level 3 corresponds to the fully open opening of the cover 202, and the control device 300 controls the drive mechanism 203 to operate, so that the cover 202 is fully opened. When the air conditioner 100 is in non-cooling mode and the fan speed is at level 1, which is lower than the second preset low level of 3, the control cover 202 is fully open. When the air conditioner 100 is in non-cooling mode and the fan speed is at level 3, which is equal to the second preset low level 3, the cover 202 is also fully opened. When the air conditioner 100 is in non-cooling mode and the fan speed is at level 6, which is higher than the second preset low level 3, according to the second mapping relationship, level 6 corresponds to a 2 / 5 opening of the cover 202. The control device 300 controls the drive mechanism 203 to open the cover 202 2 / 5.

[0076] The humidification function of the air conditioner 100 in this embodiment of the invention can be activated automatically or manually. A humidity detection device 107 is provided on the outside of the air conditioner 100 to detect the indoor air humidity value.

[0077] When the air conditioner 100 starts in automatic mode, it automatically detects the indoor air humidity. It then determines the relationship between the indoor air humidity and a first preset humidity threshold and a second preset humidity threshold, where the second preset humidity threshold is greater than the first preset humidity threshold. When the indoor air humidity is lower than the first preset humidity threshold, the air conditioner 100 automatically starts humidifying. When the indoor air humidity is higher than the second preset humidity threshold, the air conditioner 100 automatically stops humidifying. The indoor air humidity can be detected every hour. Typically, the suitable relative humidity (RH) for a comfortable indoor environment is 40%-55%. The first preset humidity threshold is 40%, and the second preset humidity threshold is 55%. When the indoor air humidity is lower than 40%, the air conditioner 100 automatically starts humidifying. When the indoor air humidity is higher than 55%, the air conditioner 100 automatically stops humidifying.

[0078] Figure 7 yes Figure 1 Another schematic diagram of the humidification control method of the air conditioner 100 shown. When the air conditioner 100 is in cooling mode, heating mode, ventilation mode, or sleep mode, the humidification control method of the air conditioner 100 in this embodiment of the invention includes the following steps:

[0079] S302: When a user's command to turn on the humidification function is received, the indoor air humidity value is obtained.

[0080] S304: Determine the relationship between the indoor air humidity value and the first preset humidity threshold and the second preset humidity threshold. When the indoor air humidity value is less than the first preset humidity threshold, proceed to step S306; when the indoor air humidity value is greater than the first preset humidity threshold and less than or equal to the second preset humidity threshold, proceed to steps S308 to S314; when the indoor air humidity value is greater than the second preset humidity threshold, proceed to steps S316 to S322.

[0081] S306: Control the air conditioner to start humidifying at 100°C.

[0082] S308: Control the air conditioner 100 to issue a first prompt message and a first inquiry message. The first prompt message is used to remind the user that the humidity is appropriate, and the first inquiry message is used to ask whether to continue to turn on the humidification function.

[0083] S310: Determine whether the user's instruction to continue humidifying the function has been received. If the result of step S310 is yes, proceed to step S312; if the result of step S310 is no, proceed to step S314.

[0084] S312: Controls the air conditioner to start humidifying at 100°C.

[0085] S314: Control the air conditioner 100 to cancel the humidification function.

[0086] S316: Control the air conditioner 100 to issue a second prompt message and a first inquiry message. The second prompt message is used to remind the user that the humidity is too high, and the first inquiry message is used to ask whether to continue to turn on the humidification function.

[0087] S318: Determine whether the user's instruction to continue humidifying the function has been received. If the result of step S318 is yes, proceed to step S320; if the result of step S318 is no, proceed to step S322.

[0088] S320: Controls the air conditioner to start humidifying at 100.

[0089] S322: Control the air conditioner 100 to cancel the humidification function.

[0090] As mentioned earlier, the first preset humidity threshold can be 40%, and the second preset humidity threshold can be 55%. The first prompt message, the second prompt message, and the first inquiry message can all be voice messages. For example, the first prompt message could be "Current humidity is suitable," the second prompt message could be "Current humidity is too high," and the first inquiry message could be "Continue to turn on the humidification function?" It is understood that the first prompt message, the second prompt message, and the first inquiry message can also be other types of information. Thus, when the air conditioner 100 is in cooling mode, heating mode, ventilation mode, or sleep mode, upon receiving a user's command to turn on the humidification function, it obtains the indoor air humidity value. When the indoor air humidity value is less than 40%, the air conditioner 100 starts humidifying. When the indoor air humidity value is greater than 40% and less than or equal to 55%, the air conditioner 100 is controlled to issue "Current humidity is suitable" and "Continue to turn on the humidification function?" If the user replies "Yes," the air conditioner 100 starts humidifying; if the user replies "No," the air conditioner 100 cancels the humidification function. When the indoor air humidity exceeds 55%, the air conditioner 100 sends a message stating "Current humidity is too high" and asking "Continue to turn on the humidification function?" If the user replies "Yes," the air conditioner 100 starts humidifying; if the user replies "No," the air conditioner 100 cancels the humidification function. This ensures that the humidification effect fully meets the user's needs.

[0091] Figure 8 yes Figure 1 This is another schematic flowchart of the humidification control method for the air conditioner 100 shown. When the air conditioner 100 is in humidification mode, the humidification control method of the air conditioner 100 according to this embodiment of the invention includes the following steps:

[0092] S402: Obtain indoor air humidity value.

[0093] S404: Determine the relationship between the indoor air humidity value and the first preset humidity threshold and the second preset humidity threshold. When the indoor air humidity value is less than the first preset humidity threshold, proceed to step S406; when the indoor air humidity value is greater than the first preset humidity threshold and less than or equal to the second preset humidity threshold, proceed to steps S408 to S414; when the indoor air humidity value is greater than the second preset humidity threshold, proceed to steps S416 to S422.

[0094] S406: Control the air conditioner to continue humidifying.

[0095] S408: Control the air conditioner 100 to send a first prompt message and a second inquiry message. The first prompt message is used to remind the user that the humidity is appropriate, and the second inquiry message is used to ask whether to continue humidifying.

[0096] S410: Determine whether the user's command to continue humidifying has been received. If the result of step S410 is yes, proceed to step S412; if the result of step S410 is no, proceed to step S414.

[0097] S412: Control the air conditioner to continue humidifying.

[0098] S414: Control the air conditioner to shut down.

[0099] S416: Control the air conditioner 100 to issue a second prompt message and a second inquiry message. The second prompt message is used to remind the user that the humidity is too high, and the second inquiry message is used to ask whether to continue humidifying.

[0100] S418: Determine whether the user's command to continue humidifying has been received. If the result of step S418 is yes, proceed to step S420; if the result of step S418 is no, proceed to step S420.

[0101] S420: Control the air conditioner to continue humidifying.

[0102] S422: Control the air conditioner to shut down.

[0103] As mentioned earlier, the first preset humidity threshold can be 40%, and the second preset humidity threshold can be 55%. The first prompt, second prompt, and second inquiry messages can all be voice messages. For example, the first prompt message could be "Current humidity is suitable," the second prompt message could be "Current humidity is too high," and the second inquiry message could be "Continue humidifying?" It is understood that the first prompt, second prompt, and second inquiry messages can also be other types of information. Thus, when the air conditioner 100 is in humidification mode, it acquires the indoor air humidity value. When the indoor air humidity value is less than 40%, the air conditioner 100 continues humidifying. When the indoor air humidity value is greater than 40% and less than or equal to 55%, the air conditioner 100 is controlled to issue "Current humidity is suitable" and "Continue humidifying?" If the user replies "Yes," the air conditioner 100 continues humidifying; if the user replies "No," the air conditioner 100 turns off. When the indoor air humidity value is greater than 55%, the air conditioner 100 is controlled to issue "Current humidity is too high" and "Continue humidifying?" If the user replies "Yes," the air conditioner 100 continues humidifying; if the user replies "No," the air conditioner 100 turns off. This ensures that the humidification effect fully meets the user's needs.

The air conditioner 100 of this embodiment further includes a water level detection device 204 within the humidifier box 200. The humidification control method of the air conditioner 100 of this embodiment also includes:

[0105] S502: Get the water level value of humidifier box 200.

[0106] S504: Determine whether the water volume value is not greater than the preset minimum water volume threshold. If the determination result of step S504 is yes, proceed to step S506.

[0107] S506: Determine the operating status of the air conditioner 100, which includes standalone humidification, auxiliary humidification, and no humidification. When the air conditioner 100 is in standalone humidification, execute step S508; when the air conditioner 100 is in auxiliary humidification, execute step S510; when the air conditioner 100 is in no humidification, execute step S512.

[0108] S508: Controls air conditioner 100 to issue a water filling prompt and then shuts down.

[0109] S510: Controls the air conditioner 100 to issue a water replenishment prompt and stop humidification.

[0110] S512: Issues a water replenishment prompt when the air conditioner is turned off at 100%.

[0111] The additional humidification state means that the air conditioner 100 is running other functions and also performing humidification, such as simultaneously running cooling and humidification functions. A prompt message can be issued via the reminder module 108, which can be a voice prompt saying "Insufficient water, please add water" three times. By using different controls for different operating states of the air conditioner 100, the humidification effect can be further guaranteed, avoiding situations where insufficient water affects humidification. In addition, when the air conditioner 100 is turned on, the water level detection device 204 can also be activated; when the water level is greater than the preset minimum water level threshold, no prompt is given; when the water level is not greater than the preset minimum water level threshold, a prompt is issued.
