[0047] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Figure 1 The flowchart of the formaldehyde removal control method of a purification device proposed in the first embodiment of the present invention is shown. The formaldehyde removal control method of the purification device provided by the present invention is applicable to the application scenario that an air conditioning device (i.e., air conditioner) is installed in the room to be purified, the purification device is placed in the room, there is a pollution source that releases formaldehyde pollutants in the room, and there is a linkage control relationship between the purification device and the air conditioning device in the current space. Figure 1 As shown, the formaldehyde removal control method of the purification equipment proposed in the embodiment of the present invention includes the following steps:

[0049] S11. The purification device obtains first formaldehyde concentration information of the current space.

[0050] In an embodiment of the present invention, a formaldehyde concentration detection sensor may be mounted on the purification device or a formaldehyde concentration detection function may be integrated inside the purification device to detect the first formaldehyde concentration information of the space where the purification device is currently located. Specifically, in an optional embodiment, at the initial time t0, the purification device turns on the purification function to remove formaldehyde from the room, and the sensor for checking the formaldehyde concentration mounted on the purification device starts working to check the formaldehyde concentration of the current space in real time. For purification devices provided with a display panel, the formaldehyde concentration can also be displayed on the display panel of the purification device, so that the user can intuitively monitor the formaldehyde concentration of the current space.

[0051] S12, the purification device determines whether the first formaldehyde concentration information is greater than a preset first concentration threshold;

[0052] If the first formaldehyde concentration information is greater than a preset first concentration threshold, step S13 is executed.

[0053] Specifically, the present invention pre-sets a first concentration threshold value, and when the formaldehyde concentration value detected by the purification device reaches the preset first concentration threshold value, linkage control is performed to execute the formaldehyde removal operation.

[0054] It is understandable that the preset first concentration threshold can be set according to the restriction data specified in the national standard, and the present invention does not specifically limit its specific value. In a specific example, the value of the first concentration threshold can be preferably set to 0.10 mg / m3. When the indoor formaldehyde concentration information is greater than the first concentration threshold, it means that the indoor formaldehyde concentration exceeds the standard and it is urgent to start the purification equipment to perform the purification operation.

[0055] S13, the purification device operates at the maximum working gear, and sends the first formaldehyde concentration information to the air conditioning device, so that the air conditioning device starts a heating mode and performs a combined formaldehyde removal operation.

[0056] In an embodiment of the present invention, when the purification device determines that the first formaldehyde concentration information it detects is greater than a preset first concentration threshold, the purification device operates at the maximum working gear and sends the first formaldehyde concentration information to the air conditioning device. When the air conditioning device receives the formaldehyde concentration information, the air conditioning device starts and turns on the heating mode with the preset indoor temperature threshold as the target heating temperature until the temperature of the entire room is balanced, and then the air conditioning device stops running.

[0057] In an optional embodiment, the purification device can transmit the first formaldehyde concentration information it detects to the air conditioning device in real time, and the air conditioning device determines whether the formaldehyde concentration information is greater than a preset first concentration threshold. When the formaldehyde concentration information received by the air conditioning device is greater than the preset first concentration threshold, the heating mode is turned on.

[0058] It is understandable that when the first formaldehyde concentration information is greater than the preset first concentration threshold, the indoor formaldehyde concentration is relatively high. In order to speed up the purification speed, the purification device operates at the maximum working gear. Among them, the maximum working gear of the purification device refers to the maximum intensity gear for formaldehyde removal. In the process of linkage between the purification device and the air conditioning device, the purification device determines the formaldehyde concentration in real time, which is convenient for judging the formaldehyde removal effect, and also convenient for the air conditioning device to control the linkage work of the equipment in time according to the formaldehyde concentration value detected by the purification device.

[0059] In this embodiment, the indoor temperature threshold value may range from 27° C. to 33° C. Preferably, the value may be 30° C. When the indoor temperature reaches 30° C., the optimal formaldehyde removal effect may be achieved.

[0060] The formaldehyde removal control method of the purification equipment provided in the embodiment of the present invention is achieved through the linkage control of the purification equipment and the air conditioning equipment. The air conditioning equipment starts heating according to the formaldehyde concentration detected by the purifier, which can accelerate the decomposition of formaldehyde and the volatilization rate of formaldehyde on the surface of formaldehyde pollutants, thereby achieving the effect of efficient and rapid formaldehyde removal.

[0061] Figure 2 The flowchart of another formaldehyde removal control method of a purification device proposed in the second embodiment of the present invention is shown. The application scenario applicable to the formaldehyde removal control method of the purification device provided by the present invention is the same as that of the first embodiment, specifically, an air conditioning device (i.e., air conditioner) is installed in the room to be purified, the purification device is placed in the room, and there is a pollution source that releases formaldehyde pollutants in the room, wherein there is a linkage control relationship between the purification device and the air conditioning device in the current space. Figure 2 As shown, the formaldehyde removal control method of the purification equipment proposed in the embodiment of the present invention includes the following steps:

[0062] S11. The purification device obtains first formaldehyde concentration information of the current space.

[0063] S12: The purification device determines whether the first formaldehyde concentration information is greater than a preset first concentration threshold.

[0064] If the first formaldehyde concentration information is greater than a preset first concentration threshold, step S13 is executed; if the first formaldehyde concentration information is less than or equal to the preset first concentration threshold, step S14 is executed.

[0065] S13. The purification device operates at a maximum working gear and sends the first formaldehyde concentration information to the air conditioning device so that the air conditioning device starts a heating mode.

[0066] S14. The purification equipment operates in automatic working gear.

[0067] In an embodiment of the present invention, when the purification device determines that the first formaldehyde concentration information detected by it is less than or equal to the preset first concentration threshold, the indoor formaldehyde concentration is relatively low. The purification device can start the automatic working gear to achieve the formaldehyde removal effect within a suitable time. At this time, the air conditioning device can be inactive.

[0068] The method for removing formaldehyde by purification equipment provided in the second embodiment of the present invention controls the purification equipment and the air conditioning equipment to work in conjunction according to the formaldehyde concentration information to achieve efficient and rapid formaldehyde removal. When the first formaldehyde concentration information is less than or equal to the preset first concentration threshold, the purification equipment is controlled to start the automatic working gear and the air conditioning equipment is not operated. This has the advantages of energy saving and emission reduction while meeting the formaldehyde removal effect.

[0069] Figure 3 The flowchart of the formaldehyde removal control method of another purification device proposed in the third embodiment of the present invention is shown. The application scenario applicable to the formaldehyde removal control method of the purification device provided by the present invention is the same as that of the first embodiment, and will not be repeated here. Figure 3 As shown, the formaldehyde removal control method of the purification equipment proposed in the embodiment of the present invention includes the following steps:

[0070] S11. The purification device obtains first formaldehyde concentration information of the current space.

[0071] S12: The purification device determines whether the first formaldehyde concentration information is greater than a preset first concentration threshold.

[0072] If the first formaldehyde concentration information is greater than a preset first concentration threshold, step S13 is executed; if the first formaldehyde concentration information is less than or equal to the preset first concentration threshold, step S14 is executed.

[0073] S13. The purification device operates at a maximum working gear and sends the first formaldehyde concentration information to the air conditioning device so that the air conditioning device starts a heating mode.

[0074] S14. The purification equipment operates in automatic working gear.

[0075] S15. When the air conditioning device is operating in a heating mode, obtain the indoor temperature of the current space.

[0076] S16, the air conditioning device determines whether the indoor temperature is greater than or equal to a preset indoor temperature threshold;

[0077] In the embodiment of the present invention, the indoor temperature threshold value may range from 27° C. to 33° C. Preferably, the value may be 30° C. When the indoor temperature reaches 30° C., the optimal formaldehyde removal effect may be achieved.

[0078] If the indoor temperature is greater than or equal to the preset indoor temperature threshold, execute step S17; if the indoor temperature is less than the preset indoor temperature threshold, execute step S18.

[0079] S17. The air conditioning equipment stops running.

[0080] S18. The purification device keeps running at the maximum working gear, and the air conditioning device keeps running in the heating mode.

[0081] It is understandable that when the indoor temperature is greater than or equal to the preset indoor temperature threshold range, it means that the current space has been heated to the optimal temperature threshold by the air conditioning equipment, and the temperature of the entire room tends to be balanced, and the optimal formaldehyde removal effect can be achieved, then step S17 is executed to control the air conditioning equipment to stop running. When the indoor temperature is less than the preset indoor temperature threshold range, it means that the optimal formaldehyde removal effect has not yet been achieved, and it is necessary to continue to maintain the heating mode of the air conditioning equipment and the maximum working gear of the purification equipment.

[0082] In this embodiment, when the air-conditioning equipment turns on the heating mode according to the formaldehyde concentration detected by the purification equipment, the air-conditioning equipment will obtain the indoor temperature of the current space during operation and compare it with the preset indoor temperature threshold. According to the changes in the indoor temperature and the comparison result between the formaldehyde concentration detection value and the preset concentration threshold, the purification equipment and the air-conditioning equipment are controlled to operate together to achieve efficient and rapid formaldehyde removal.

[0083] Figure 4 The flowchart of the formaldehyde removal control method of another purification device proposed in the fourth embodiment of the present invention is shown. The application scenario applicable to the formaldehyde removal control method of the purification device provided by the present invention is the same as that of the first embodiment, and will not be repeated here. Figure 4 As shown, the formaldehyde removal control method of the purification equipment proposed in the embodiment of the present invention includes the following steps:

[0084] S21. The purification device obtains first formaldehyde concentration information of the current space.

[0085] S22: The purification device determines whether the first formaldehyde concentration information is greater than a preset first concentration threshold.

[0086] If the first formaldehyde concentration information is greater than the preset first concentration threshold, step S23 is executed; if the first formaldehyde concentration information is less than or equal to the preset first concentration threshold, step S24 is executed.

[0087] S23: The purification device operates at the maximum working gear and sends the first formaldehyde concentration information to the air conditioning device so that the air conditioning device starts a heating mode.

[0088] S24. The purification equipment operates in automatic working gear.

[0089] S25. When the air conditioning device is operating in a heating mode, obtain the indoor temperature of the current space.

[0090] S26, the air conditioning device determines whether the indoor temperature is greater than or equal to a preset indoor temperature threshold;

[0091] In the embodiment of the present invention, the indoor temperature threshold value may range from 27° C. to 33° C. Preferably, the value may be 30° C. When the indoor temperature reaches 30° C., the optimal formaldehyde removal effect may be achieved.

[0092] If the indoor temperature is greater than or equal to the preset indoor temperature threshold, execute step S27; if the indoor temperature is less than the preset indoor temperature threshold, execute step S30.

[0093] S27, the purification device obtains second formaldehyde concentration information of the current space, wherein the second concentration threshold is less than or equal to the first concentration threshold.

[0094] S28, the purification device determines whether the second formaldehyde concentration information is greater than or equal to a preset second concentration threshold;

[0095] If the second formaldehyde concentration information is less than the preset second concentration threshold, execute step S29; if the second formaldehyde concentration information is greater than or equal to the preset second concentration threshold, execute step S30.

[0096] S29. The purification device operates in an automatic working gear and sends the second formaldehyde concentration information to the air conditioning device to stop the air conditioning device.

[0097] In the embodiment of the present invention, in order to avoid the situation where a high concentration of formaldehyde still exists in the room after the air conditioning device stops running, and the air conditioning device has been shut down at this time, resulting in failure to achieve the effect of efficient formaldehyde removal. Therefore, before the air conditioning device stops running, the purification device obtains the second formaldehyde concentration information of the current space, and when the second formaldehyde concentration information is less than the preset second concentration threshold, that is, when the indoor formaldehyde concentration is low, the air conditioning device is stopped again, so as to avoid the air conditioning device stopping heating under the condition of high formaldehyde concentration, which will trigger the start mode again, thereby avoiding frequent switching of the working mode of the air conditioning device.

[0098] S30: The purification device keeps running at the maximum working gear, and the air conditioning device keeps running in the heating mode.

[0099] In the embodiment of the present invention, after the air conditioning equipment stops running, it will not affect the operating state of the purification equipment. In actual applications, the purification time interval can be preset according to user needs to make the purification equipment automatically stop running; the purification equipment can also run in an automatic working gear and maintain the automatic working gear until the user operates the purification equipment to stop running, which is convenient and flexible to operate.

[0100] The method for removing formaldehyde by purification equipment provided in the fourth embodiment of the present invention controls the operation of the air-conditioning equipment for a certain period of time according to the comparison result between the indoor temperature and the preset temperature threshold value, and then combines the comparison result between the second formaldehyde concentration detection value and the preset concentration threshold value to jointly control the purification equipment and the air-conditioning equipment to achieve efficient and rapid formaldehyde removal; avoids the frequent switching of the working mode of the air-conditioning equipment, realizes precise control of the air-conditioning equipment, and improves the user experience.
