[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 starts the heating mode in the case of no one indoors, accelerates the release of indoor formaldehyde, and until the indoor formaldehyde concentration is greater than the first set concentration.

[0039] S03, the air conditioner performs formaldehyde removal operation.

[0040] In the case that there is a person in the room, the formaldehyde removal operation is directly performed to avoid the release of formaldehyde in the indoor decoration materials from damaging the health of the person in the room.

[0041] The method for removing formaldehyde from an air conditioner provided by the embodiment of the present disclosure acquires indoor personnel information in response to a control instruction for formaldehyde removal. In the case that there is no person in the room, a heating mode is started to accelerate the release of formaldehyde in the room until the formaldehyde concentration in the room is greater than a first set concentration, and finally the formaldehyde removal operation is performed. Before the formaldehyde removal, heating is performed by the air conditioner to make the formaldehyde in the indoor decoration materials be completely released, so that more thorough formaldehyde removal can be performed in the room, the situation that the user has to frequently remove formaldehyde due to the continuous release of formaldehyde in the indoor decoration materials is avoided, and the user experience is improved.

[0042] In combination with Figure 2 The embodiment of the present disclosure provides a method for removing formaldehyde from an air conditioner, which comprises the following steps:

[0043] S01, the air conditioner acquires indoor personnel information in response to a control instruction for formaldehyde removal.

[0044] S21, the air conditioner determines a target release temperature of formaldehyde according to the current environmental parameters in the room in the case that there is no person in the room.

[0045] S22, the air conditioner starts heating and adjusts the temperature in the room to the target release temperature to accelerate the release of formaldehyde in the room until the formaldehyde concentration in the room is greater than a first set concentration.

[0046] S03, the air conditioner performs the formaldehyde removal operation.

[0047] The method for removing formaldehyde from an air conditioner provided by the embodiment of the present disclosure, because the release rate of formaldehyde in decoration materials is different under different temperatures of different environmental parameters in the room. Therefore, in order to make the formaldehyde in the decoration materials be quickly released, the air conditioner determines a target release temperature of formaldehyde according to the current environmental parameters in the room in the case that there is no person in the room. Then the air conditioner starts heating and adjusts the temperature in the room to the target release temperature, so as to accelerate the release of formaldehyde in the room until the formaldehyde concentration in the room is greater than a first set concentration. In this way, the formaldehyde in the room is completely released, so that the formaldehyde removal can be more thorough.

[0048] Optionally, the formaldehyde removal operation performed by the air conditioner comprises: the air conditioner starts a blowing mode and starts an extractor hood to discharge the formaldehyde in the room to the outside; and the air conditioner closes the extractor hood and the air conditioner in the case that the formaldehyde concentration in the room is less than a second set concentration.

[0049] In this way, after the formaldehyde in the indoor decoration materials is completely released, the air conditioner starts the air supply function to accelerate the air circulation in the room, and meanwhile, the range hood is started to discharge the formaldehyde in the indoor air to the outdoor, so that the formaldehyde removal is more complete.

[0050] In combination Figure 3 As shown in the accompanying drawings, the embodiment of the present disclosure provides a method for removing formaldehyde by an air conditioner, comprising:

[0051] S01, the air conditioner acquires indoor personnel information in response to a control instruction for removing formaldehyde.

[0052] S02, the air conditioner starts a heating mode to accelerate the release of formaldehyde in the room under the condition that there is no one in the room, until the formaldehyde concentration in the room is greater than a first set concentration.

[0053] S31, the air conditioner controls the spraying device to spray the corresponding formaldehyde removal agent according to the indoor personnel information, and starts an air supply function to diffuse the formaldehyde removal agent in the room.

[0054] S32, the air conditioner starts the range hood to discharge the formaldehyde removal agent to the outdoor under the condition that the formaldehyde removal is completed.

[0055] By using the method for removing formaldehyde by the air conditioner provided in the embodiment of the present disclosure, the air conditioner controls the spraying device to spray the corresponding formaldehyde removal agent according to the indoor personnel information, and starts an air supply function to diffuse the formaldehyde removal agent in the room. And under the condition that the formaldehyde removal is completed, the range hood is started to discharge the formaldehyde removal agent to the outdoor. The formaldehyde removal agent is diffused to all places in the room by the air supply of the air conditioner, so that the formaldehyde removal is simultaneously performed in all places in the room, avoiding the situation that the process of removing formaldehyde from the indoor air is limited by the structure of the air conditioner, resulting in a low formaldehyde removal efficiency. The formaldehyde removal efficiency is improved, the indoor air is rapidly and real-timely removed of formaldehyde is realized. In addition, after the formaldehyde removal is completed, the range hood is started to rapidly discharge the residual formaldehyde removal agent in the room to the outdoor, reducing the influence of the residual formaldehyde removal agent on the user.

[0056] In combination Figure 4 As shown in the accompanying drawings, the embodiment of the present disclosure provides a method for removing formaldehyde by an air conditioner, comprising:

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

[0058] S02, the air conditioner starts a heating mode to accelerate the release of formaldehyde in the room under the condition that there is no one in the room, until the formaldehyde concentration in the room is greater than a first set concentration.

[0059] S41, the air conditioner determines the target formaldehyde removal agent corresponding to the indoor personnel information according to a preset first relationship.

[0060] S42, 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 room.

[0061] S32, the air conditioner starts the range hood to discharge the de-aldehyde agent to the outdoor in the case that the de-aldehyde is completed.

[0062] The indoor personnel information includes physiological information and environmental information that the de-aldehyde agent may have adverse effects on the user, for example, the gender, race, age, and disease condition of the indoor personnel, and information such as whether the user exists in the room and the number of users in the room.

[0063] The method for de-aldehyde of the air conditioner provided by the embodiment of the present disclosure is adopted, 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 room. Based on the indoor personnel information, the target de-aldehyde agent is determined through the first relationship, which can make the de-aldehyde process select the de-aldehyde agent most suitable for the current indoor condition, so that the target de-aldehyde agent is matched with the actual condition of the current room, and the de-aldehyde process is avoided to have adverse effects on the user.

[0064] Optionally, the air conditioner determines the target de-aldehyde agent corresponding to the indoor personnel information according to the preset first relationship, which includes: the air conditioner determines the first de-aldehyde agent harmless to the human body as the target de-aldehyde agent in the case that the user exists in the room; and the air conditioner determines the 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 no user exists in the room.

[0065] The first de-aldehyde agent can be chlorine dioxide. Chlorine dioxide has strong oxidizing property, and the oxidizing property is 2.5 times that of chlorine. Therefore, chlorine dioxide can react with most organic compounds, such as formaldehyde, amines, and mercaptans. 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, and it is internationally recognized that gaseous chlorine dioxide is non-toxic to the human body, so 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 a spray containing active oxygen, such as ozone spray, which has better de-aldehyde effect than chlorine dioxide, but has certain effects 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.

[0066] In this way, the air conditioner determines the first de-aldehyde agent that is harmless to human body as the target de-aldehyde agent when there is a human in the room. The air conditioner determines the second de-aldehyde agent that has a better de-aldehyde effect than the first de-aldehyde agent as the target de-aldehyde agent when there is no human in the room. In this way, the room can be de-aldehyde in real time by the corresponding de-aldehyde agent regardless of whether there is a human in the room currently, and the de-aldehyde efficiency is improved.

[0067] Optionally, the air conditioner controls the spraying device to spray the target de-aldehyde agent, including: the air conditioner determines the target environment parameter according to the target de-aldehyde agent; the air conditioner adjusts the environment parameter in the room to the target environment parameter when there is no human in the room; and the air conditioner adjusts the environment parameter in the room according to the user setting parameter of the air conditioner and the target environment parameter, and starts the air supply function to make the de-aldehyde agent diffuse in the room when there is a human in the room.

[0068] The target environment parameter includes an environment parameter that affects the de-aldehyde effect of the target de-aldehyde agent, such as temperature, humidity, illumination, and the like. The air conditioner can also change the environment parameter in the room by linking other household electrical appliances, so as to make the environment parameter in the room more conducive to the de-aldehyde effect of the target de-aldehyde agent, for example, by linking the control of the electric curtain and / or the electric door and window to change the illumination in the room, by linking the control of the humidifier to humidify the room, and the like.

[0069] The air conditioner determines the target environment parameter corresponding to the target de-aldehyde agent according to the second relationship stored in advance, so that the target environment parameter is matched with the best de-aldehyde effect of the target de-aldehyde agent.

[0070] In this way, the air conditioner can determine the target environment parameter that is conducive to the de-aldehyde effect of the target de-aldehyde agent according to the target de-aldehyde agent. When there is no human in the room, the environment parameter in the room is adjusted to the target environment parameter, so that the environment in the room is conducive to promoting the de-aldehyde effect of the target de-aldehyde agent. When there is a human in the room, in order to avoid the adjustment of the environment parameter affecting the user, the environment parameter in the room is adjusted according to the user setting parameter of the air conditioner and the target environment parameter, so as to balance the user experience and the de-aldehyde effect of the target de-aldehyde agent.

[0071] Optionally, the air conditioner adjusts the environment parameter in the room according to the user setting parameter of the air conditioner and the target environment 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 environment parameter in the room to the first upper limit value when the target environment parameter is greater than or equal to the user setting parameter; and the air conditioner adjusts the environment parameter in the room to the first lower limit value when the target environment parameter is less than or equal to the user setting parameter.

[0072] Thus, the air conditioner determines the first upper limit value and the first lower limit value according to the user set parameter and the first correction value. The adjustment range of the air conditioner can be limited to avoid affecting the user experience due to the adjustment of the target formaldehyde removal agent to remove formaldehyde. In the case where the target environment parameter is greater than or equal to the user set parameter, the indoor environment parameter is adjusted to the first upper limit value. In the case where the target environment parameter is less than or equal to the user set parameter, the indoor environment parameter is adjusted to the first lower limit value. On the basis of avoiding affecting the user experience, the environment parameter is closer to the target environment parameter, so as to take into account the effect of the target formaldehyde removal agent on removing formaldehyde and achieve a balance between the user experience and improving the formaldehyde removal effect of the target formaldehyde removal agent.

[0073] In combination Figure 5 As shown in the accompanying drawings, the embodiment of the present disclosure provides a method for removing formaldehyde by an air conditioner, comprising:

[0074] S01, the air conditioner acquires indoor personnel information in response to a control instruction for removing formaldehyde.

[0075] S02, the air conditioner starts a heating mode in the case where there is no one in the room to accelerate the release of indoor formaldehyde until the indoor formaldehyde concentration is greater than a first set concentration.

[0076] 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 indoor formaldehyde removal agent.

[0077] S52, the air conditioner closes the spraying device and starts a fan to perform air supply in the case where the first current concentration is greater than the first concentration, so that the formaldehyde removal agent is diffused in the room.

[0078] S32, the air conditioner starts an extractor hood to discharge the formaldehyde removal agent to the outdoor in the case where the formaldehyde removal is completed.

[0079] In the case where the formaldehyde removal effect of the formaldehyde removal agent may be affected under different environment parameters, the first concentration is determined according to the indoor environment. For example, the first concentration of the formaldehyde removal agent can be determined according to the indoor temperature, humidity, space volume, illumination and the like, and specifically can be determined according to one or more parameter combinations, so as to obtain the optimal concentration of the formaldehyde removal agent under the current environment and further improve the formaldehyde removal efficiency.

[0080] The method for removing formaldehyde provided by the embodiment of the present disclosure is used for the air conditioner to control the spraying device to spray the corresponding formaldehyde removal agent according to the indoor personnel information, and to detect the first current concentration of the indoor formaldehyde removal agent. 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 formaldehyde removal agent is diffused in the indoor space. In the case that the concentration of the formaldehyde removal agent reaches the first concentration, the concentration of the formaldehyde removal agent just reaches the degree of effectively removing formaldehyde in the entire indoor space at this time, and therefore the fan is started to send the formaldehyde removal agent to each part of the indoor space, thereby improving the efficiency of removing formaldehyde.

[0081] 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.

[0082] In this way, in the case that the first current concentration is greater than the first concentration, the air conditioner closes the spraying device, and 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 formaldehyde removal agent is diffused in the indoor space. Because the required time for the formaldehyde removal agent to effectively remove formaldehyde is different in different spaces and under different concentrations of the formaldehyde removal agent. Therefore, the air conditioner controls the fan to operate at the target rotating speed and the target time length, so that the formaldehyde removal agent is sufficiently diffused in the indoor space, while avoiding the situation that the air supply time is too long, the energy is wasted, or the air supply time is too short, and the formaldehyde removal agent has not yet taken effect.

[0083] Optionally, the air conditioner judges whether the formaldehyde removal is completed, including: the air conditioner detects the concentration of the indoor formaldehyde removal agent in real time; and the air conditioner determines that the formaldehyde removal is completed in the case that the concentration of the indoor formaldehyde removal agent is greater than the second concentration and lasts for the first time length.

[0084] The second concentration is less than the first concentration. Because the fan blows the formaldehyde removal agent at the first concentration to each part of the indoor space, the concentration is reduced in this process due to the diffusion of the formaldehyde removal agent to each part of the indoor space. The second concentration is determined according to the first concentration and the volume of the indoor space, so as to ensure that the effective formaldehyde removal can be achieved in the entire indoor space.

[0085] 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 the case that the concentration of the indoor formaldehyde removal agent is greater than the second concentration and lasts for the first time length. In the 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.

[0086] Optionally, the air conditioner starts the range hood, including: the air conditioner determines the 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 the third concentration.

[0087] Thus, the air conditioner determines the target gear of the range hood according to the second current concentration of the indoor aldehyde removal agent, and starts the range hood at the target gear until the concentration of the indoor aldehyde removal agent is less than the third concentration. In the case that the removal of formaldehyde is completed, the air conditioner needs to timely discharge the aldehyde removal agent to the outdoor. Therefore, in order to discharge the aldehyde 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 aldehyde removal agent, so that the target gear matches the current concentration of the indoor aldehyde removal agent, and starts the range hood to discharge the aldehyde removal agent to the outdoor according to the target gear. The aldehyde 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 completion of the removal of formaldehyde and the time node of the user's return home, 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 aldehyde 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 in turn affects the health of the user, and balance the internal and external pressure difference. In the case that the third current concentration is less than the third concentration, the concentration of the indoor aldehyde removal agent is within the safe range that the user's body can accept or the range in which the irritating odor is negligible, and therefore the air conditioner turns off the range hood.

[0088] Optionally, before the air conditioner obtains the indoor personnel information, the air conditioner further 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 in the case that the first location and the second location are isolated, the air conditioner exits the formaldehyde removal control and notifies the user.

[0089] The user can remotely send a control instruction to open the door or 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 aldehyde removal agent.

[0090] Thus, 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 in the case that the first location and the second location are isolated, the air conditioner exits the formaldehyde removal control and notifies the user. In order to ensure that the aldehyde 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 aldehyde removal agent in the air supply area to the outdoor. If the first location and the second location are isolated, the range hood cannot work, and even if it is forcibly operated, it will increase the energy consumption.

[0091] In combination Figure 6As shown, the embodiment of the present disclosure provides a device 300 for removing formaldehyde by air conditioner, comprising a processor 301 and a memory 101.
