The environmental conditioning apparatus 110 may include at least a humidifier 112 for humidifying the indoor environment, and an ozone generator 111 that generates ozone for sterilizing the indoor environment.

The memory 140 may store a computer program 141. The computer program 141 is adapted to be executed by the processor 130 for performing the method of sterilization of an indoor environment according to an embodiment of the invention.

In particular, the processor 130 may be configured to obtain a control instruction for performing ozone sterilization on the indoor environment, and when the control instruction for performing ozone sterilization is obtained, the indoor environment is first humidified by the humidifier 112, and when the humidity of the indoor environment is greater than or equal to a preset first humidity, the ozone generator 111 is used to generate ozone to perform ozone sterilization on the indoor environment.

In the present invention, humidity refers to relative humidity, and the preset first humidity may be 60% to 70%, for example, 60%, 65%, or 70%.

When receiving the control instruction of ozone sterilization, the environment adjusting system 100 of the present invention humidifies the indoor environment, and when the humidity reaches the preset first humidity, the ozone generator 111 is started to generate ozone to perform sterilization, so as to ensure that the sterilization has a higher ozone concentration, and at the same time, the ozone sterilization capability under the same ozone concentration is improved, thereby improving the efficiency of ozone sterilization as a whole, and making the sterilization more thorough.

In some embodiments, after activating the ozone generator 111, the processor 130 may be configured to continue to humidify the indoor environment by using the humidifier 112, so that the humidity of the indoor environment is kept within the preset humidity range, so as to further improve the ozone sterilization capability at the same ozone concentration, improve the sterilization efficiency, and make the sterilization more thorough. The predetermined humidity range may be 75% to 95%.

In some embodiments, the environment conditioning apparatus 110 may further include a temperature conditioning device 114 for conditioning an ambient temperature of the indoor environment.

The processor 130 may be configured to, after acquiring the control instruction for performing ozone sterilization on the indoor environment, perform temperature adjustment on the indoor environment according to a preset temperature by using the temperature adjustment device 114 in the environment adjustment apparatus 110, so as to quickly increase the relative humidity of the indoor environment, thereby improving the sterilization efficiency and shortening the sterilization time. The predetermined temperature may be 20 to 25 ℃, for example, 20 ℃, 22 ℃, 24 ℃ or 25 ℃. The temperature adjustment of the indoor environment by the temperature adjustment device 114 may be performed prior to the activation of the humidifier 112 or may be performed simultaneously with the activation of the humidifier 112.

In some embodiments, the environmental conditioning apparatus 110 may further include an airflow disruption device 113 for air circulation to the indoor environment to facilitate indoor air flow.

When the humidity of the indoor environment is greater than or equal to the preset first humidity, that is, when the ozone generator 111 is started, the processor 130 may be configured to utilize the airflow disturbance device 113 to promote the air flow in the indoor environment, so that the ozone fills the entire indoor environment, and the sterilization is more sufficient and thorough.

Specifically, the processor 130 may be configured to promote the air flow in the indoor environment at a preset first rotation speed by using the airflow disturbance device 113 when the humidity of the indoor environment is greater than or equal to a preset first humidity and less than a preset second humidity; when the humidity of the indoor environment is greater than or equal to the preset second humidity, the air flow disturbing device 113 is used for promoting the air flow in the indoor environment according to the preset second rotating speed.

The preset second humidity can be greater than the preset first humidity, and the preset second humidity can be 65-75%, such as 65%, 70% or 75%, so as to ensure the high efficiency of sterilization.

Predetermine the second rotational speed and can be less than predetermineeing first rotational speed, reduce the air flow velocity of indoor environment promptly to guarantee ozone concentration, and then improve degerming effect and efficiency.

The preset second rotation speed may be 50% to 70%, such as 50%, 60% or 70%, of the rated rotation speed of the airflow disturbing device 113, so as to avoid unnecessary energy loss.

In some embodiments, the processor 130 may be configured to control the humidifier 112 and the ozone generator 111 to stop humidifying and ozone sterilizing the indoor environment when the time for performing ozone sterilization on the indoor environment by using the ozone generator 111 is greater than or equal to a preset first time, so as to avoid unnecessary energy waste.

In some further embodiments, the processor 130 may be further configured to communicate the indoor environment with the outdoor environment when the time for stopping ozone sterilization for the indoor environment is greater than or equal to the preset second time, so as to ensure efficiency and sufficiency of ozone sterilization and avoid damage of ozone to human body. The mode of communicating the indoor environment with the outdoor environment can be to start a fresh air fan or open a window.

In some embodiments, the control instructions for ozone sterilization of the indoor environment may include an immediate sterilization instruction and a periodic sterilization instruction. The environmental conditioning device 110 may sterilize the indoor environment immediately upon receiving the immediate sterilization instruction; and when the regular degerming instruction is received, degerming the indoor environment according to the degerming time set by the user. In the present invention, the periodic sterilization may be a single sterilization performed at a predetermined time point, or may be a periodic sterilization performed a plurality of times.

The environmental conditioning system 100 may also include at least one user terminal 120 to remotely send instructions to the processor 130. In the present invention, at least one is one, two, or more than two. That is, the climate regulating device 110 may be in data signal connection with one or more user terminals 120 via the processor 130.

In some embodiments, in which the periodic degerming instruction is received, the processor 130 may be configured to provide prompt information for degerming the indoor environment to at least one user terminal 120, and degerming the indoor environment when a confirmation instruction of any user terminal 120 responding to the prompt information is received, so as to avoid a situation that the user returns to or stays in the indoor environment during degerming due to not seeing the prompt information, and reduce a potential safety hazard.

The processor 130 may be further configured to obtain time information for periodically sterilizing the indoor environment set by the user and determine an execution time for providing the prompt message, and when the execution time is reached, provide the prompt message for sterilizing the indoor environment to the at least one user terminal 120. For example, the time information may be to start sterilizing the indoor environment three hours a week, and the execution time may be two and a half hours a week, five afternoons.

In some embodiments, in which the immediate sterilization instruction is received, the processor 130 may be configured to receive the immediate sterilization instruction sent by any one of the user terminals 120, record the sending time of the immediate sterilization instruction and the sending times corresponding to the sending time, and display the sending time with the largest sending times to the user when acquiring the time information for performing sterilization on the indoor environment regularly set by the user, so as to facilitate the user operation.

In some further embodiments, the processor 130 may be configured to send an alert message to each user terminal 120 after receiving a confirmation instruction in response to the reminder information or after receiving an immediate sterilization instruction. The reminder message may include at least one of a safety reminder, a time required for the sterilization, and a progress of the sterilization to avoid the user returning or staying in the indoor environment during the sterilization process.

In some further embodiments, after receiving the confirmation instruction in response to the prompt or after receiving the immediate sterilization instruction, the processor 130 may be configured to detect whether the indoor environment is someone or determine whether any one of the users is returning to the indoor environment on the way, and continue until the sterilization is finished, so as to prevent the user from returning to the indoor environment during the sterilization process due to ignoring the safety prompt or not knowing the progress of the sterilization.

Specifically, before the indoor environment is humidified by the humidifier 112 in the environment adjusting apparatus 110, i.e., before the sterilization procedure is started, the processor 130 may be configured to start humidifying the indoor environment by the humidifier 112 in the environment adjusting apparatus 110 when it is detected that the indoor environment is not.

After the step of humidifying the indoor environment using the humidifier 112 in the environment adjusting apparatus 110, i.e., during the sterilization process, the processor 130 may be configured to stop humidifying and ozone sterilizing the indoor environment when detecting that there is a person in the indoor environment.

The processor 130 may be configured to track current tracking information of a corresponding user by using a positioning system of the user terminal 120, and determine whether a destination indicated by the current tracking information (i.e., a destination of the user) is an indoor environment according to the current tracking information. And if the destination indicated by the current trace information of any user is judged to be the indoor environment, stopping sterilizing the indoor environment.

The processor 130 may be configured to acquire at least one historical trace information related to the indoor environment of the corresponding user by using the positioning system of the user terminal 120, determine, for each user terminal 120, a trace overlap degree between the current trace information and the at least one historical trace information, and determine, according to the trace overlap degree, whether a destination indicated by the current trace information is an indoor environment, so as to improve accuracy of determining whether the destination indicated by the current trace information is an indoor environment. And if the track coincidence degree of the current track information and any historical track information is greater than or equal to a preset coincidence threshold value, judging that the destination indicated by the current track information is an indoor environment.

Processor 130 may determine a course of action and a time of action from the current whereabouts information and the at least one historical whereabouts information, respectively. The track contact degree can be calculated according to the route contact degree of the current track information and at least one historical track information on the running route and the time contact degree on the action time according to the preset balance weight. For the current track information, the action route can be a route from an origin to the current position, and the action time can be a time period from the departure time to the current time; for historical track information, the action route may be a route from an origin to a destination, and the action time may be a time period from a departure time to an arrival time.

The counter weight of the route coincidence degree can be larger than the counter weight of the time coincidence degree, so that the accuracy of judging whether the destination of the current track information is an indoor environment is further improved. For example, a route overlap weight is 70% and a time overlap weight is 30%; the route overlap ratio was found to be 60% and the time overlap ratio was found to be 40%.

In the case where the user terminal 120 is running navigation software for route navigation, the processor 130 may also be configured to directly read the destination of the navigation route, and determine whether the user is on the way to return to the indoor environment by determining whether the destination is address information of the indoor environment.

In the present invention, the environmental conditioning apparatus 110 may be a unitary component. For example, the environment conditioning device 110 may be an air conditioner, and the airflow disturbance device 113 may be an indoor unit fan of the air conditioner; the temperature adjusting device 114 can be an indoor unit heat exchanger of the air conditioner; the humidifier 112 can be arranged in the indoor unit casing of the air conditioner and is provided with an independent humidifying fan; the ozone generator 111 can be arranged at an air outlet of an indoor unit fan as a module so as to blow out ozone generated by the ozone generator 111 to an indoor environment by using the indoor unit fan, and the ozone generator 111 can also be arranged on an air inlet flow path of the indoor unit fan so as to generate ozone to sterilize indoor air with certain humidity humidified by the humidifier 112 and blow out the sterilized air to the indoor environment by the indoor unit fan; the processor 130 may be disposed in the indoor unit casing of the air conditioner.

Fig. 2 is a schematic flow chart of a sterilization method of an indoor environment according to an embodiment of the present invention, which shows a sterilization flow of ozone sterilization.
