[0035] The embodiments of the present disclosure disclose an air conditioner, comprising: a spraying device for spraying an aldehyde removal agent. The air conditioner can extract the aldehyde removal agent in the liquid storage tank through the electric device and spray it into the air through the spraying device. Wherein, the air conditioner also has an extractor hood associated with the air conditioner arranged indoors, and electric doors and windows at various places.

[0036] Based on the structure of the air conditioner described above, in combination with Figure 1 As shown in the figure, the embodiments of the present disclosure provide a method for removing formaldehyde from an air conditioner, comprising:

[0037] S01, the air conditioner acquires indoor personnel information in response to the control instruction for removing formaldehyde.

[0038] S02, the air conditioner controls the spraying device to spray the corresponding formaldehyde remover according to the indoor occupant information, and starts the air supply function to diffuse the formaldehyde remover in the room.

[0039] S03, when the air conditioner completes the formaldehyde removal, the range hood is started to discharge the formaldehyde removal agent to the outside.

[0040] The method for removing formaldehyde from an air conditioner provided by the embodiment of the present disclosure is adopted. In response to the control instruction for formaldehyde removal, the information of the people in the room is obtained, so that according to the information of the people in the room, the spraying device is controlled to spray the corresponding formaldehyde remover, and the air supply function is started to diffuse the formaldehyde remover in the room. When the formaldehyde removal is completed, the range hood is started to discharge the formaldehyde remover to the outside. The formaldehyde remover is diffused to various places in the room by the air supply of the air conditioner, so that formaldehyde is removed from various places in the room at the same time, avoiding the situation in which the formaldehyde removal efficiency is low due to the structural limitation of the air conditioner during the formaldehyde removal process of the indoor air, thereby improving the efficiency of formaldehyde removal and realizing rapid and real-time formaldehyde removal of the indoor air. In addition, after the formaldehyde removal is completed, the formaldehyde remover remaining in the room is quickly discharged to the outside by starting the range hood, reducing the impact of the residual formaldehyde remover on the user.

[0041] Combine Figure 2 As shown, the embodiment of the present disclosure provides a method for removing formaldehyde from an air conditioner, comprising:

[0042] S01, the air conditioner obtains indoor occupant information in response to a formaldehyde removal control instruction.

[0043] S21, the air conditioner determines a target formaldehyde remover corresponding to the indoor occupant information according to a preset first relationship.

[0044] S22, the air conditioner controls the spraying device to spray the target formaldehyde remover and starts the air supply function to diffuse the formaldehyde remover in the room.

[0045] S03, when the air conditioner completes the formaldehyde removal, the range hood is started to discharge the formaldehyde removal agent to the outside.

[0046] Among them, indoor personnel information includes physiological information and environmental information that may have adverse effects on users of formaldehyde removers, such as the gender, race, age, physical illness of indoor personnel, whether there are users indoors, the number of indoor users, and other information.

[0047] The method for removing formaldehyde from the air conditioner provided by the embodiment of the present disclosure is used. The air conditioner determines the target de-aldehyde agent corresponding to the indoor personnel information according to the preset first relationship, controls the spraying device to spray the target de-aldehyde agent, and starts the air supply function to diffuse the de-aldehyde agent in the indoor. The target de-aldehyde agent is determined by the first relationship based on the indoor personnel information, which can select the de-aldehyde agent most suitable for the current indoor condition in the process of removing formaldehyde, so that the target de-aldehyde agent matches the actual situation of the current indoor, and the process of removing formaldehyde avoids adverse effects on the user.

[0048] In combination Figure 3 The embodiment of the present disclosure provides a method for removing formaldehyde from an air conditioner, which comprises:

[0049] S01, the air conditioner acquires indoor personnel information in response to a control instruction for removing formaldehyde.

[0050] S31, the air conditioner determines a first de-aldehyde agent harmless to human body as the target de-aldehyde agent in the case that there is someone in the indoor.

[0051] S32, the air conditioner determines a second de-aldehyde agent with better de-aldehyde effect than the first de-aldehyde agent as the target de-aldehyde agent in the case that there is no one in the indoor.

[0052] S22, the air conditioner controls the spraying device to spray the target de-aldehyde agent, and starts the air supply function to diffuse the de-aldehyde agent in the indoor.

[0053] S03, the air conditioner starts the range hood to discharge the de-aldehyde agent to the outdoor in the case that the removal of formaldehyde is completed.

[0054] The first de-aldehyde agent can be chlorine dioxide. Chlorine dioxide has strong oxidizing property, which is 2.5 times of that of chlorine. Therefore, it can react with most organic compounds, such as formaldehyde, amines, mercaptans, etc. After the reaction, these organic compounds can be converted into non-toxic and harmless substances such as carbon dioxide, so chlorine dioxide has the effect of removing formaldehyde. And gaseous chlorine dioxide has no harmful by-products. Since gaseous chlorine dioxide is internationally recognized as non-toxic to the human body, it can be used in a human-machine coexistence environment. In this way, the formaldehyde molecules in the space can be quickly eliminated in real time in the presence of people. The recognized high-efficiency de-aldehyde ability and safety of gaseous chlorine dioxide solve the problem of secondary pollution caused by the saturation of traditional adsorption de-aldehyde materials. The second de-aldehyde agent can be active oxygen-containing spray, such as ozone spray, which has better de-aldehyde effect than chlorine dioxide, but has certain influence on the human body. Therefore, it needs to be used when the user is not at home, or the de-aldehyde agent in the air needs to be removed as soon as possible after use.

[0055] The method for removing formaldehyde provided by the embodiment of the present disclosure is used in the air conditioner. When people exist in the indoor environment, the air conditioner determines a first formaldehyde removal agent harmless to human bodies as the target formaldehyde removal agent. When no people exist in the indoor environment, the air conditioner determines a second formaldehyde removal agent with a better formaldehyde removal effect than the first formaldehyde removal agent as the target formaldehyde removal agent. In this way, the indoor environment can be removed of formaldehyde in real time by the corresponding formaldehyde removal agent regardless of whether people exist in the indoor environment at present, and the formaldehyde removal efficiency is improved.

[0056] In combination with Figure 4 The embodiment of the present disclosure provides a method for removing formaldehyde in an air conditioner, which comprises the following steps:

[0057] S01, the air conditioner acquires indoor personnel information in response to a control instruction for removing formaldehyde.

[0058] S21, the air conditioner determines a target formaldehyde removal agent corresponding to the indoor personnel information according to a preset first relationship.

[0059] S41, the air conditioner determines a target environmental parameter according to the target formaldehyde removal agent.

[0060] S42, the air conditioner adjusts the environmental parameter in the indoor environment to the target environmental parameter when no people exist in the indoor environment.

[0061] S43, the air conditioner adjusts the environmental parameter in the indoor environment according to the user setting parameter of the air conditioner and the target environmental parameter, and starts the air supply function to diffuse the formaldehyde removal agent in the indoor environment when people exist in the indoor environment.

[0062] S03, the air conditioner starts the range hood to discharge the formaldehyde removal agent to the outdoor environment when the formaldehyde removal is completed.

[0063] The target environmental parameter comprises an environmental parameter affecting the formaldehyde removal effect of the target formaldehyde removal agent, for example, temperature, humidity, illumination, and the like. The air conditioner can also change the environmental parameter in the indoor environment by linking other household electrical appliances to make the environmental parameter in the indoor environment more conducive to the formaldehyde removal effect of the target formaldehyde removal agent, for example, by linking the control of the electric curtain and / or the electric door and window to change the illumination in the indoor environment, by linking the control of the humidifier to humidify the indoor environment, and the like.

[0064] The air conditioner determines the target environmental parameter according to the target formaldehyde removal agent. Specifically, the target environmental parameter corresponding to the target formaldehyde removal agent can be determined according to a second relationship saved in advance, so that the target environmental parameter is matched with the best formaldehyde removal effect of the target formaldehyde removal agent.

[0065] The method for removing formaldehyde provided by the embodiment of the present disclosure can be used for the air conditioner to determine the target environmental parameter that is beneficial to the target formaldehyde removal agent to exert the formaldehyde removal effect. In the case that there is no one in the room, the environmental parameter in the room is adjusted to the target environmental parameter, so that the indoor environment is beneficial to promoting the formaldehyde removal effect of the target formaldehyde removal agent. In the case that there is someone in the room, in order to avoid the adjustment of the environmental parameter affecting the user, the environmental parameter in the room is adjusted according to the user setting parameter of the air conditioner and the target environmental parameter, and the needs of the user for the indoor environment and the needs of the formaldehyde removal effect of the target formaldehyde removal agent for the formaldehyde removal environment are considered, so that the balance between the user experience and the improvement of the formaldehyde removal effect of the target formaldehyde removal agent is achieved.

[0066] Optionally, the air conditioner adjusts the environmental parameter in the room according to the user setting parameter of the air conditioner and the target environmental parameter, including: the air conditioner determines the first upper limit value and the first lower limit value according to the user setting parameter and the first correction value; the air conditioner adjusts the environmental parameter in the room to the first upper limit value in the case that the target environmental parameter is greater than or equal to the user setting parameter; and the air conditioner adjusts the environmental parameter in the room to the first lower limit value in the case that the target environmental parameter is less than or equal to the user setting parameter.

[0067] In this way, the air conditioner determines the first upper limit value and the first lower limit value according to the user setting parameter and the first correction value. The adjustment range of the air conditioner can be limited, and the user experience is avoided from being affected by the adjustment of the formaldehyde removal environment of the target formaldehyde removal agent. In the case that the target environmental parameter is greater than or equal to the user setting parameter, the environmental parameter in the room is adjusted to the first upper limit value. In the case that the target environmental parameter is less than or equal to the user setting parameter, the environmental parameter in the room is adjusted to the first lower limit value. On the basis of avoiding affecting the user experience, the environmental parameter is closer to the target environmental parameter, so that the formaldehyde removal effect of the target formaldehyde removal agent is considered, and the balance between the user experience and the improvement of the formaldehyde removal effect of the target formaldehyde removal agent is achieved.

[0068] In combination with Figure 5 The embodiment of the present disclosure provides a method for removing formaldehyde by an air conditioner, including:

[0069] S01, the air conditioner acquires indoor personnel information in response to a control instruction for removing formaldehyde.

[0070] S51, the air conditioner controls the spraying device to spray the corresponding formaldehyde removal agent according to the indoor personnel information, and detects a first current concentration of the formaldehyde removal agent in the room.

[0071] S52, the air conditioner closes the spraying device and starts the fan to perform air supply in the case that the first current concentration is greater than the first concentration, so that the formaldehyde removal agent is diffused in the room.

[0072] S03, the air conditioner starts the range hood to discharge the formaldehyde removal agent to the outdoor in the case that the formaldehyde removal is completed.

[0073] The first concentration is determined according to the indoor environment, because the de-aldehyde effect of the de-aldehyde agent may be affected under different environmental parameters. For example, the first concentration of the de-aldehyde agent can be determined according to the indoor temperature, humidity, space volume, illumination, or the like, or according to a combination of one or more of the above parameters, so that the optimal concentration of the de-aldehyde agent under the current environment can be obtained, and the de-aldehyde efficiency is further improved.

[0074] The method for de-aldehyde of the air conditioner provided by the embodiments of the present disclosure is adopted, the air conditioner controls the spraying device to spray the corresponding de-aldehyde agent according to the indoor personnel information, and detects the first current concentration of the de-aldehyde agent in the room. In the case that the first current concentration is greater than the first concentration, the air conditioner closes the spraying device and starts the fan to perform air supply, so that the de-aldehyde agent is diffused in the room. In the case that the concentration of the de-aldehyde agent reaches the first concentration, the concentration of the de-aldehyde agent just reaches the effective de-aldehyde degree in the whole room at this time, so the fan is started to send the de-aldehyde agent to each place in the room, and the de-aldehyde efficiency is improved.

[0075] Optionally, the air conditioner starts the fan to perform air supply, including: the air conditioner determines the target rotating speed and the target time length corresponding to the first current concentration according to the first current concentration; and the air conditioner controls the fan to operate at the target rotating speed and the target time length.

[0076] In this way, in the case that the first current concentration is greater than the first concentration, the air conditioner closes the spraying device, determines the target rotating speed and the target time length corresponding to the first current concentration according to the first current concentration, and finally controls the fan to operate at the target rotating speed and the target time length, so that the de-aldehyde agent is diffused in the room. Because the required time for the de-aldehyde agent to effectively de-aldehyde is different in different spaces and under different concentrations of the de-aldehyde agent, the air conditioner controls the fan to operate at the target rotating speed and the target time length, so that the de-aldehyde agent is sufficiently diffused in the indoor space, while avoiding the situation that the air supply time is too long, energy is wasted, or the air supply time is too short, and the de-aldehyde agent has not yet taken effect.

[0077] Optionally, the air conditioner judges whether the de-aldehyde is completed, including: the air conditioner detects the concentration of the de-aldehyde agent in the room in real time; and the air conditioner determines that the de-aldehyde is completed in the case that the concentration of the de-aldehyde agent in the room is greater than the second concentration and lasts for the first time length.

[0078] The second concentration is less than the first concentration. Because the fan blows the de-aldehyde agent at the first concentration to each place in the room, the concentration is reduced in this process due to the diffusion of the de-aldehyde agent blown to each place in the room. The second concentration is determined according to the first concentration and the volume of the room, so that effective de-aldehyde can be achieved in the whole room.

[0079] In this way, the air conditioner detects the concentration of the indoor formaldehyde removal agent in real time, and determines that the formaldehyde removal is completed in a case that the concentration of the indoor formaldehyde removal agent is greater than the second concentration and lasts for the first time length. In a case that the concentration of the formaldehyde removal agent reaches the second concentration and the action time length reaches the first time length, at this time, the formaldehyde removal agent has fully played a role and has the effect of removing formaldehyde, and therefore, it can be determined that the formaldehyde removal is completed.

[0080] Optionally, the air conditioner starts the range hood, comprising: the air conditioner determines a target gear of the range hood according to the second current concentration of the indoor formaldehyde removal agent; and the air conditioner starts the range hood at the target gear until the concentration of the indoor formaldehyde removal agent is less than a third concentration.

[0081] In this way, the air conditioner determines the target gear of the range hood according to the second current concentration of the indoor formaldehyde removal agent, and starts the range hood at the target gear until the concentration of the indoor formaldehyde removal agent is less than the third concentration. In a case that the formaldehyde removal is completed, the air conditioner needs to timely discharge the formaldehyde removal agent to the outdoor. Therefore, in order to discharge the formaldehyde removal agent to the outdoor within a set time, the air conditioner determines the target gear of the range hood according to the second current concentration of the indoor formaldehyde removal agent, so that the target gear matches the current concentration of the indoor formaldehyde removal agent, and starts the range hood at the target gear to discharge the formaldehyde removal agent to the outdoor. The formaldehyde removal agent is discharged to the outdoor within the set time. The set time can be determined according to user setting, or can be determined according to the time difference between the time node of the formaldehyde removal completion and the time node of the user's return, so as to maximize the use of the time period when the user is not at home to remove formaldehyde, make the process of removing the formaldehyde removal agent more moderate, avoid the power of the range hood being too large, cause the internal and external pressure difference to be too large, and cause the external pollutants to enter the indoor, which affects the health of the user, and balance the internal and external pressure difference. In a case that the third current concentration is less than the third concentration, at this time, the concentration of the indoor formaldehyde removal agent is within a safe range that the user's body can accept or a range in which irritating odor is negligible, and therefore, the air conditioner closes the range hood.

[0082] Optionally, before the air conditioner obtains the indoor personnel information, the air conditioner further comprises: the air conditioner obtains a first location of a space where the range hood is located and a second location of a space where the air conditioner is located; and the air conditioner exits the formaldehyde removal control in a case that the first location and the second location are isolated, and notifies the user.

[0083] The user can remotely send a control instruction to open the door or the window to make the first location and the second location common after receiving the information that the first location and the second location are isolated, so as to continue to start the range hood to remove the residual formaldehyde removal agent.

[0084] In this way, the air conditioner obtains a first position of a space where the range hood is located and a second position of a space where the air conditioner is located, and in the case that the first position and the second position are isolated, the air conditioner exits the formaldehyde removal control and notifies the user. In order to ensure that the formaldehyde removal agent in the air supply area of the air conditioner can be removed, it is necessary to ensure that the range hood is in communication with the air supply area of the air conditioner, so that the range hood can timely suck the formaldehyde removal agent in the air supply area to the outdoor. If the first position and the second position are isolated, the range hood cannot work, even if it is forced to run, it will also increase the energy consumption.

[0085] In combination Figure 6 As shown in the drawings, the embodiment of the present disclosure provides a device 300 for removing formaldehyde from an air conditioner, which comprises a processor 301 and a memory 101. Optionally, the device can also comprise a communication interface 102 and a bus 103.
