Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a method and apparatus for sterilizing air conditioners, an air conditioner, and a storage medium. Background Technology

[0002] Currently, air conditioners are typically used indoors to cool or heat the air. When using air conditioners, users usually close doors and windows, preventing air circulation between indoors and outdoors. This allows harmful bacteria, microorganisms, and viruses in the indoor air to multiply and proliferate, seriously endangering users' health. Viruses and bacteria are ubiquitous, floating in the air, invisible and intangible, and multiply rapidly. Therefore, effectively eliminating airborne bacteria and viruses has become an urgent problem to solve.

[0003] The related technology discloses an air purification method for an air conditioner. The air conditioner includes a purification duct and a heat exchange duct. The heat exchange duct has an air outlet, and at least one of a horizontal guide vane and a vertical guide vane is installed on the air outlet. An air purification component is installed inside the purification duct. The air purification method of the air conditioner involves: controlling the operation of fans in the purification duct and the heat exchange duct; and controlling the rotation of at least one of the horizontal guide vane and the vertical guide vane. By simultaneously activating the fans in the purification duct and the heat exchange duct, and combined with the rotation of the horizontal guide vane and / or the vertical guide vane at the air outlet to disturb the indoor airflow, the indoor air circulation is strengthened, increasing the amount of air entering the purification duct. Most of the indoor air is purified by the purification component inside the purification duct, thereby improving the purification effect of the air conditioner.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Using relevant technologies to collect indoor air through circulation for in-machine disinfection and purification can eliminate indoor bacteria to a certain extent. However, due to the size limitations of air conditioners, the air duct space is limited, resulting in low sterilization efficiency and the inability to achieve rapid and real-time disinfection and sterilization of indoor air.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0007] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] This disclosure provides a method and apparatus for sterilizing an air conditioner, an air conditioner, and a storage medium to avoid the situation where the sterilization efficiency is low due to the size limitation of the air conditioner during the sterilization process of indoor air, thereby improving the sterilization efficiency and realizing rapid real-time sterilization of indoor air.

[0009] In some embodiments, the air conditioner includes a spraying device for spraying a disinfectant; the method includes: in response to a disinfection control command, acquiring indoor occupant information; according to the indoor occupant information, controlling the spraying device to spray a corresponding disinfectant and activating the air supply function to diffuse the disinfectant indoors; and, upon completion of disinfection, activating the range hood to exhaust the disinfectant outdoors.

[0010] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to execute the method for sterilizing an air conditioner when the program instructions are executed.

[0011] In some embodiments, the air conditioner includes:

[0012] Air conditioner body;

[0013] Spraying device for spraying disinfectant; and,

[0014] The aforementioned device for sterilizing air conditioners is installed on the air conditioner body.

[0015] In some embodiments, the storage medium stores program instructions that, when executed, perform the above-described method for sterilizing an air conditioner.

[0016] The method and apparatus for sterilizing air conditioners, the air conditioner, and the storage medium provided in this disclosure can achieve the following technical effects:

[0017] Responding to sterilization control commands, the system acquires information about the occupants indoors. Based on this information, it controls the spraying device to spray the corresponding sterilizing agent and activates the air supply function to diffuse the sterilizing agent throughout the room. Finally, upon completion of sterilization, the range hood is activated to exhaust the sterilizing agent outdoors. By distributing the sterilizing agent throughout the room via the air conditioning system, sterilization is achieved simultaneously in all areas, avoiding the limitations imposed by the air conditioner's size during sterilization and thus improving efficiency. This enables rapid, real-time sterilization of indoor air. Furthermore, after sterilization, the range hood is activated to quickly exhaust any remaining sterilizing agent outdoors, minimizing any potential impact on users.

[0033] In this embodiment of the disclosure, smart home appliances refer to home air conditioners formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent sensing, and intelligent application. The operation of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage smart home appliances.

[0034] In the disclosed embodiments, the terminal device refers to an electronic device with wireless connectivity. The terminal device can communicate with the aforementioned smart home appliances via the internet, or directly via Bluetooth, Wi-Fi, or other methods. In some embodiments, the terminal device may be, for example, a mobile device, a computer, or an in-vehicle device built into a hovercraft, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, or any combination thereof. Wearable devices may include, for example, smartwatches, smart bracelets, pedometers, etc.

[0035] This disclosure provides an air conditioner, including a spraying device for spraying a disinfectant. The air conditioner is capable of drawing disinfectant from a storage tank via an electric device and spraying it into the air through the spraying device. The air conditioner also includes an indoor-installed range hood associated with it, and electrically operated doors and windows in various locations.

[0036] Based on the above-mentioned structure of the air conditioner, combined with Figure 1 As shown in the embodiments of this disclosure, a method for sterilizing an air conditioner is provided, comprising:

[0037] S01, the air conditioner responds to the sterilization control command and obtains information about the people in the room.

[0038] S02, the air conditioner controls the spraying device to spray the corresponding disinfectant based on the information of the people in the room, and starts the air supply function to diffuse the disinfectant in the room.

[0039] S03, after the air conditioner has completed sterilization, start the range hood to discharge the sterilizing agent to the outside.

[0040] The method for sterilizing an air conditioner provided in this disclosure, in response to a sterilization control command, acquires indoor occupant information. Based on the occupant information, the spraying device is controlled to spray the corresponding sterilizing agent, and the air supply function is activated to diffuse the sterilizing agent indoors. Finally, upon completion of sterilization, the range hood is activated to exhaust the sterilizing agent outdoors. By dispersing the sterilizing agent throughout the room through the air supply of the air conditioner, sterilization is carried out simultaneously throughout the room, avoiding the situation where the sterilization efficiency is low due to the size limitation of the air conditioner during the sterilization process, thus improving the sterilization efficiency and achieving rapid and real-time sterilization of indoor air. In addition, after sterilization is completed, the range hood is activated to quickly exhaust any remaining sterilizing agent outdoors, reducing the impact of residual sterilizing agent on users.

[0041] Combination Figure 2 As shown in the embodiments of this disclosure, a method for sterilizing an air conditioner is provided, comprising:

[0042] S01, the air conditioner responds to the sterilization control command and obtains information about the people in the room.

[0043] S21, the air conditioner determines the target disinfectant corresponding to the indoor occupant information based on the preset first relationship.

[0044] S22, the air conditioner controls the spraying device to spray the target disinfectant and starts the air supply function to diffuse the disinfectant indoors.

[0045] S03, after the air conditioner has completed sterilization, start the range hood to discharge the sterilizing agent to the outside.

[0046] The indoor personnel information includes physiological and environmental information that may have adverse effects on users from disinfectants, such as the gender, ethnicity, age, and health conditions of the indoor personnel, as well as whether there are users in the room and the number of users in the room.

[0047] The air conditioner sterilization method provided in this embodiment determines a target sterilizing agent corresponding to indoor occupant information based on a preset first relationship, controls a spraying device to spray the target sterilizing agent, and activates the air supply function to diffuse the sterilizing agent indoors. By determining the target sterilizing agent based on indoor occupant information and the first relationship, the sterilization process can select the most suitable sterilizing agent for the current indoor conditions, ensuring a good match between the target sterilizing agent and the actual indoor situation, thus avoiding any adverse effects on the user during the sterilization process.

[0048] Combination Figure 3 As shown in the embodiments of this disclosure, a method for sterilizing an air conditioner is provided, comprising:

[0049] S01, the air conditioner responds to the sterilization control command and obtains information about the people in the room.

[0050] S31, when people are present in the room, the air conditioner uses a first disinfectant that is determined to be harmless to the human body as the target disinfectant.

[0051] S32, when no one is in the room, the air conditioner selects a second disinfectant that has a better disinfection effect than the first disinfectant as the target disinfectant.

[0052] S22, the air conditioner controls the spraying device to spray the target disinfectant and starts the air supply function to diffuse the disinfectant indoors.

[0053] S03, after the air conditioner has completed sterilization, start the range hood to discharge the sterilizing agent to the outside.

[0054] The first disinfectant can be hypochlorous acid, which produces no harmful byproducts and can kill airborne germs more effectively and quickly. Since hypochlorous acid is internationally recognized as non-toxic to humans, it can be used in the presence of people and machines. This allows for rapid and real-time elimination of airborne germs even in occupied environments, achieving immediate prevention and control. The second disinfectant can be sodium hypochlorite solution, which has a better disinfecting effect than hypochlorous acid, but may have some impact on human health. Therefore, it should be used when the user is not at home, or the disinfectant should be removed from the air as soon as possible after use.

[0055] The air conditioner sterilization method provided in this disclosure identifies a first sterilizing agent that is harmless to humans as the target sterilizing agent when someone is present in the room. When no one is present in the room, a second sterilizing agent with a better sterilization effect than the first sterilizing agent is selected as the target sterilizing agent. This allows for real-time sterilization of the room using the corresponding sterilizing agent regardless of whether anyone is currently present, significantly improving sterilization efficiency.

[0056] Combination Figure 4 As shown in the embodiments of this disclosure, a method for sterilizing an air conditioner is provided, comprising:

[0057] S01, the air conditioner responds to the sterilization control command and obtains information about the people in the room.

[0058] S41, the air conditioner controls the spraying device to spray the corresponding disinfectant based on the indoor occupant information, and detects the first current concentration of the indoor disinfectant.

[0059] S42, when the current concentration is greater than the first concentration, the air conditioner shuts off the spraying device and starts the fan to blow air, so that the disinfectant can diffuse in the room.

[0060] S03, after the air conditioner has completed sterilization, start the range hood to discharge the sterilizing agent to the outside.

[0061] Since the sterilization effect of disinfectants may be affected by different environmental parameters, the initial concentration is determined based on the indoor environment. For example, the initial concentration of the disinfectant can be determined based on parameters such as indoor temperature, humidity, and space volume. Specifically, it can be determined based on one or more of these parameters in combination, thereby obtaining the optimal sterilization concentration under the current environment and further improving sterilization efficiency.

[0062] The method for sterilizing an air conditioner provided in this embodiment involves the air conditioner controlling a spraying device to spray a corresponding sterilizing agent based on indoor occupant information, and detecting a first current concentration of the sterilizing agent indoors. When the first current concentration exceeds a certain threshold, the air conditioner shuts off the spraying device and starts a fan to circulate air, allowing the sterilizing agent to diffuse throughout the room. When the sterilizing agent concentration reaches the first threshold, which is sufficient for effective sterilization throughout the room, the fan is activated to deliver the sterilizing agent to all areas of the room, improving sterilization efficiency.

[0063] Combination Figure 5 As shown in the embodiments of this disclosure, a method for sterilizing an air conditioner is provided, comprising:

[0064] S01, the air conditioner responds to the sterilization control command and obtains information about the people in the room.

[0065] S41, the air conditioner controls the spraying device to spray the corresponding disinfectant based on the indoor occupant information, and detects the first current concentration of the indoor disinfectant.

[0066] S51, if the first current concentration is greater than the first concentration, the air conditioner shuts off the spray device and determines the target speed and target duration corresponding to the first current concentration based on the first current concentration.

[0067] S52, the air conditioner controls the fan to run at the target speed and target duration, so that the disinfectant can be diffused indoors.

[0068] S03, after the air conditioner has completed sterilization, start the range hood to discharge the sterilizing agent to the outside.

[0069] The method for sterilizing an air conditioner provided in this disclosure involves shutting off the spraying device when the first current concentration is greater than a first concentration. Based on the first current concentration, a target rotation speed and target duration are determined, and finally, the fan is controlled to operate at the target rotation speed and target duration to diffuse the sterilizing agent indoors. Since the time required for the sterilizing agent to effectively sterilize varies in different spaces and at different sterilizing agent concentrations, controlling the air conditioner fan to operate at the target rotation speed and target duration ensures sufficient diffusion of the sterilizing agent in the indoor space while avoiding excessively long air supply times that waste energy, or excessively short air supply times that prevent the sterilizing agent from taking effect.

[0070] Optionally, the air conditioner determines whether sterilization is complete by: the air conditioner detecting the concentration of the indoor sterilizing agent in real time; and the air conditioner determining that sterilization is complete when the concentration of the indoor sterilizing agent is greater than a second concentration and remains so for a first duration.

[0071] The second concentration is lower than the first concentration. As the fan blows the disinfectant at the first concentration throughout the room, the concentration decreases as the disinfectant diffuses throughout the room. The second concentration is determined based on the first concentration and the volume of the room to ensure effective disinfection throughout the entire room.

[0072] In this way, the air conditioner monitors the concentration of the indoor disinfectant in real time, and determines that disinfection is complete when the concentration of the indoor disinfectant is greater than the second concentration and remains so for the first duration. When the disinfectant concentration reaches the second concentration and the duration of action reaches the first duration, the disinfectant has fully exerted its effect and achieved disinfection; therefore, disinfection can be determined to be complete.

[0073] Optionally, the air conditioner starts the range hood, including: the air conditioner determines the target setting of the range hood based on the second current concentration of the indoor disinfectant; the air conditioner starts the range hood according to the target setting until the concentration of the indoor disinfectant is less than the third concentration.

[0074] In this way, the air conditioner determines the target setting of the range hood based on the second current concentration of the indoor disinfectant, and starts the range hood at the target setting until the concentration of the indoor disinfectant is lower than the third concentration. After disinfection is complete, the air conditioner needs to promptly expel the disinfectant outdoors. Therefore, to expel the disinfectant outdoors within the set time, the air conditioner determines the target setting of the range hood based on the second current concentration of the indoor disinfectant, matching the target setting with the current concentration of the indoor disinfectant, and starts the range hood at the target setting to expel the disinfectant outdoors. This achieves the goal of expelling the disinfectant outdoors within the set time. The set time can be determined by the user's settings, or it can be determined based on the time difference between the completion of disinfection and the user's return home, thereby maximizing the use of the time when the user is not home for disinfection. This makes the disinfectant removal process more gradual, avoids excessive range hood power causing excessive pressure difference between indoors and outdoors, allowing external pollutants to enter the room and negatively impacting the user's health, and achieves a balance in the pressure difference between indoors and outdoors. When the concentration of the third disinfectant is lower than the third concentration, the concentration of the indoor disinfectant is within a safe range that is acceptable to the user's body or within a range where the irritating odor is negligible. Therefore, the air conditioner should turn off the range hood.

[0075] Optionally, before the air conditioner obtains information about the people in the room, it also includes: the air conditioner obtaining a first location of the space where the range hood is located and a second location of the space where the air conditioner is located; and when the air conditioner is isolated from the first location and the second location, it exits the sterilization control and notifies the user.

[0076] After receiving information that the first and second locations are isolated, the user can remotely send control commands to open the door or window, allowing the first and second locations to be connected, thereby continuing to start the range hood to remove residual disinfectant.

[0077] In this way, the air conditioner obtains the first position and the second position of the space where the range hood is located. If the first and second positions are isolated, the air conditioner exits sterilization control and notifies the user. To ensure that the disinfectant in the air conditioner's air supply area is removed, the range hood must be connected to the air supply area. This allows the range hood to promptly extract the disinfectant from the air supply area to the outside. If the first and second positions are isolated, the range hood will not function, and even if forced to run, it will only increase energy consumption.

[0078] Optionally, when the air conditioner determines that the sterilization function needs to be activated, it may also include: the air conditioner determining the target temperature and target humidity based on the sprayed sterilizing agent; and adjusting the indoor temperature and humidity according to the target temperature and target humidity until sterilization is completed.

[0079] Since the disinfectant's disinfection effect varies under different temperatures and humidity levels, adjusting the indoor temperature and humidity to the target temperature and humidity can enhance the disinfectant's effectiveness and improve disinfection efficiency.
