Figure 1 As shown, in the embodiment of the present invention, the air conditioner includes a formaldehyde removal module and an exhaust module, and the control method of the air conditioner mainly includes the following steps S101-S102.

[0053] Step S101: obtaining the formaldehyde concentration in the air.

[0054] In this embodiment, the formaldehyde concentration in the indoor air can be obtained by a formaldehyde detection device.

[0055] In one embodiment, the formaldehyde detection device may be disposed inside the air conditioner or inside the online controller.

[0056] Step S102: When the formaldehyde concentration is greater than a preset formaldehyde safety concentration, the exhaust module and the formaldehyde removal module are controlled to be turned on, and the exhaust module is selectively controlled according to the formaldehyde concentration to enable the formaldehyde removal module to absorb formaldehyde in the air.

[0057] In this embodiment, when the formaldehyde concentration in the indoor air is greater than the preset formaldehyde safety concentration, the exhaust module and the formaldehyde removal module are controlled to be turned on, and the exhaust module is selectively controlled according to the formaldehyde concentration to enable the formaldehyde removal module to absorb formaldehyde in the air. Those skilled in the art can customize the formaldehyde safety concentration according to actual conditions.

[0058] In one embodiment, the formaldehyde removal module may include an adsorbent and a baffle. When the formaldehyde removal module opens the control baffle to allow the adsorbent to contact the indoor air, and when the formaldehyde removal module closes the control baffle to isolate the adsorbent from the indoor air, the adsorbent may be nano active mineral.

[0059] In one embodiment, see the attached Figure 2 , Figure 2 1 is a schematic flow chart of main steps for selectively controlling an exhaust module according to formaldehyde concentration according to an implementation of an embodiment of the present invention. Step S102 may include the following steps S1021 to S1023:

[0060] Step S1021: Determine the concentration range of the formaldehyde concentration according to the formaldehyde concentration.

[0061] Step S1022: According to the concentration range, control the exhaust module to execute the operation mode corresponding to the concentration range.

[0062] Step S1023: When the operation mode is executed, the formaldehyde concentration in the current air is obtained and the process jumps to step S1021.

[0063] In this embodiment, the concentration range of the formaldehyde concentration is first determined based on the formaldehyde concentration, and then the exhaust module is controlled to execute the operation mode corresponding to the concentration range based on the concentration range. When the operation mode is executed, the formaldehyde concentration in the current air is obtained, and the process jumps to the step of "determining the concentration range of the formaldehyde concentration based on the formaldehyde concentration".

[0064] In one embodiment, those skilled in the art can customize the number of concentration intervals according to actual conditions.

[0065] In one embodiment, see the attached Figure 3 , Figure 3 1 is a schematic flow chart of main steps of determining the concentration interval of formaldehyde concentration according to formaldehyde concentration according to an implementation of an embodiment of the present invention. Step S1021 may include the following steps S10211 to S10213:

[0068] Step S10213: when the formaldehyde concentration is less than or equal to the second preset concentration and greater than the formaldehyde safety concentration, determine that the concentration interval of the formaldehyde concentration is the third concentration interval.

[0069] In this embodiment, when the formaldehyde concentration is greater than the first preset concentration, the concentration interval in which the formaldehyde concentration is located is determined to be the first concentration interval; when the formaldehyde concentration is less than or equal to the first preset concentration and greater than the second preset concentration, the concentration interval in which the formaldehyde concentration is located is determined to be the second concentration interval; when the formaldehyde concentration is less than or equal to the second preset concentration and greater than the formaldehyde safety concentration, the concentration interval in which the formaldehyde concentration is located is determined to be the third concentration interval.

[0070] In one embodiment, those skilled in the art may customize the first preset concentration, the second preset concentration, and the third preset concentration according to actual conditions, as long as the size relationship among the first preset concentration, the second preset concentration, and the third preset concentration is satisfied.

[0071] In this embodiment, the operation mode may include a first operation mode, a second operation mode, and a third operation mode, and step S1022 may further include the following steps S10221 to S10223:

[0072] Step S10221: When in the first concentration interval, control the exhaust module to execute the first operation mode.

[0073] Step S10222: When in the second concentration interval, control the exhaust module to execute the second operation mode.

[0074] Step S10223: When in the third concentration interval, control the exhaust module to execute the third operation mode.

[0075] In this embodiment, the first operation mode is to control the exhaust module to operate at a first preset speed for a first preset time; the second operation mode is to control the exhaust module to operate at a second preset speed for a second preset time; the third operation mode is to control the exhaust module to operate at a third preset speed for a third preset time. The first preset speed is greater than the second preset speed and greater than the third preset speed.

[0076] In one embodiment, the first preset speed may be W+200 rpm, the second preset speed may be W+100 rpm, and the third preset speed may be W rpm, where W is greater than zero.

[0077] In one embodiment, those skilled in the art may customize the first preset speed, the second preset speed, and the third preset speed according to actual conditions, as long as the size relationship among the first preset speed, the second preset speed, and the third preset speed is satisfied.

[0078] In one implementation, those skilled in the art may customize the first preset duration, the second preset duration, and the third preset duration according to actual conditions.

[0079] In one implementation, step S1021 may include the following steps S10214:

[0080] Step S10214: when the formaldehyde concentration is less than or equal to the formaldehyde safety concentration, determine that the concentration interval of the formaldehyde concentration is the fourth concentration interval.

[0081] In this embodiment, when the formaldehyde concentration in the indoor air is less than or equal to the formaldehyde safety concentration, the concentration interval in which the formaldehyde concentration is located is determined to be the fourth concentration interval.

[0082] In one embodiment, the formaldehyde safety concentration is less than a third preset concentration.

[0083] In one implementation, the operation mode may include a fourth operation mode, and step S1022 may further include the following steps S10224:

[0084] Step S10224: When in the fourth concentration interval, the exhaust module is controlled to execute the fourth operation mode, and the formaldehyde removal module is controlled to be turned off, and step S1023 is no longer executed.

[0085] In this embodiment, when in the fourth concentration interval, the exhaust module is controlled to execute the fourth operation mode, and the formaldehyde removal module is controlled to be turned off, and the step of "obtaining the current formaldehyde concentration in the air after the operation mode is completed" is no longer executed.

[0086] In one embodiment, the fourth operation mode may be to control the exhaust module to be closed.

[0087] In one implementation, step S102 may further include the following steps S1024 to S1025:

[0088] Step S1024: When the formaldehyde concentration is greater than the formaldehyde safety concentration, a prompt message is issued.

[0089] Step S1025: According to the instruction input by the user based on the prompt information, the exhaust module and the formaldehyde removal module are controlled to turn on.

[0090] In this embodiment, when the formaldehyde concentration in the indoor air is greater than the formaldehyde safety concentration, the air conditioner can issue a prompt message, and the user can control the exhaust module and the formaldehyde removal module to turn on based on the instructions input by the prompt message.

[0091] In one implementation, the input command may be a voice command.

[0092] Based on the above steps S101-S102, the present invention obtains the formaldehyde concentration in the air, and when the formaldehyde concentration is greater than the preset formaldehyde safety concentration, controls the exhaust module and the formaldehyde removal module to open, and selectively controls the exhaust module according to the formaldehyde concentration, so as to enable the formaldehyde removal module to absorb formaldehyde in the air. Through the above configuration, the present invention selectively controls the exhaust module and the formaldehyde removal module to open according to the formaldehyde concentration. By controlling the exhaust module to exhaust, the fluidity of formaldehyde in the indoor air is improved, thereby improving the efficiency of the formaldehyde removal module in absorbing formaldehyde in the air, and adjusting the exhaust module accordingly according to the formaldehyde concentration, the intelligent level of formaldehyde removal of the air conditioner is improved.

[0093] In one embodiment, the air conditioner control method further includes the following steps S103 to S105:

[0094] Step S103: When the formaldehyde concentration is greater than the formaldehyde safety concentration, the current indoor temperature is obtained.

[0095] Step S104: Determine whether the indoor temperature is lower than the first preset temperature within a fourth preset time period. If yes, execute step S105.

[0096] Step S105: The heating mode is turned on until the indoor temperature is greater than the second preset temperature and lasts for a fourth preset time, and then the heating mode is exited.

[0097] In this embodiment, when the formaldehyde concentration is greater than the formaldehyde safety concentration, the current indoor temperature is obtained. It is determined whether the indoor temperature is always less than the first preset temperature within a fourth preset time. If so, the heating mode is turned on until the indoor temperature is greater than the second preset temperature and continues for the fourth preset time, and then the heating mode is exited. Among them, the first preset temperature is less than the second preset temperature. When the indoor temperature is low, the formaldehyde volatilization speed is slow, and the formaldehyde volatilization efficiency can be improved by increasing the indoor temperature, and then the formaldehyde removal module and the exhaust module are controlled to comprehensively improve the formaldehyde removal efficiency of the air conditioner.

[0098] In one implementation, the fourth preset duration may be ten minutes.

[0099] In one embodiment, since the volatilization point of formaldehyde is 19 degrees Celsius, the first preset temperature may be 19 degrees Celsius.

[0100] In one embodiment, the second preset temperature may be twenty-three degrees Celsius.
