[0046] The elevator air conditioner provided by the embodiment of the present application is installed on the top or side wall of the elevator, and comprises a compressor, a first heat exchanger, a second heat exchanger, an electronic expansion valve, a four-way valve and the like. Different elements are connected through refrigerant pipelines to form a refrigerant circulation loop, and the first heat exchanger and the second heat exchanger are both provided with a fan, so that the temperature and air speed in the elevator can be adjusted. The elevator air conditioner further comprises an ultraviolet disinfection device, which is installed on the top of the elevator and can irradiate ultraviolet rays towards the bottom of the elevator, and the irradiation intensity of the ultraviolet rays can be adjusted. The elevator air conditioner further comprises a temperature detection device and a biological recognition device. The temperature detection device is installed on the top of the elevator or the inner wall opposite to the elevator door, and is arranged opposite to the elevator entrance, so that the body temperature of the person can be detected at the first time when the person enters the elevator. The biological recognition device is installed on the top or side wall of the elevator, and is used to detect the number of persons in the elevator and the in-out situation of the persons, wherein the in-out situation of the persons is determined by the increase or decrease of the number of persons.

[0047] According to the control method of the elevator air conditioner provided by the first aspect of the present application, please refer to Figures 1-2 , which comprises:

[0048] S100, in response to the elevator door opening signal, the body temperature of the person entering the elevator is acquired.

[0049] S200, if the body temperature of the person is greater than or equal to the preset temperature, the fan of the elevator air conditioner is controlled to stop running, and the ultraviolet disinfection device is controlled to disinfect the air in the elevator for a preset time after all the persons in the elevator leave the elevator.

[0050] In step S100, when the elevator stops at the bottom floor of a high-rise building or any high floor, the elevator door opening signal is formed when the person presses the up or down button. When the elevator air conditioner control device receives the elevator door opening signal, the body temperature of the person entering the elevator is detected by the temperature detection device. The position of the temperature detection device is opposite to the elevator entrance, so that the body temperature of the person can be detected at the first time when the person enters the elevator.

[0051] In some cases, the temperature detection device uses multiple detections when detecting the body temperature of people entering the elevator. For example, it detects the body temperature at the 0th second, 3rd second, and 6th second after entering the elevator. The purpose of multiple detections of the body temperature of the person is to avoid the influence of the outdoor ambient temperature on the temperature of the head skin of the person. For example, in winter, the outdoor ambient temperature is low, and the head skin cools down under the action of cold air. It can only recover after a certain period of time after the person enters the room and the elevator. Therefore, after the person enters the elevator, the body temperature of the person is detected multiple times at intervals of a unit time, which can eliminate the influence of the outdoor ambient temperature on the body temperature. The principle is that the first few detections can determine the changes in the body temperature to the actual temperature, and the next few detections can determine whether the body temperature has stabilized, thereby ensuring the authenticity of the detection results.

[0052] In step S200, when there are multiple people, the number of people's body temperatures can also vary. Determining that a person's body temperature is greater than or equal to a preset temperature means that at least one person's temperature is greater than or equal to a preset temperature, for example, ≥37.3 degrees Celsius. At this point, the elevator's air conditioning fan is controlled to stop operating to reduce the air flow rate within the elevator, preventing the air exhaled by the fevered person from spreading within the elevator or contaminating other passengers, thereby minimizing the spread of the influenza virus. Secondly, when a fever is detected in the elevator, the number of people in the elevator is continuously monitored using a biometric recognition device. An increase in the number of people indicates that someone has entered the elevator, while a decrease in the number of people indicates that someone has exited the elevator. Therefore, the number of people can be 0, 1, 2, 3, 4, etc. The number of people entering and exiting the elevator can be represented by 0, ±1, ±2, ±3, ±4, etc. In some cases, only 1 indicates that someone is in the elevator, and 0 indicates that all people have left the elevator. When it is determined that all people in the elevator have left the elevator, the ultraviolet disinfection device is controlled to disinfect the air in the elevator for a preset duration. The preset duration can be 30 seconds, or it can be determined based on the elevator's spatial structure and the intensity of the ultraviolet radiation. Ultraviolet disinfection sterilizes the air in the elevator that has been exposed to people with a fever, preventing subsequent passengers from coming into contact with air that may have carried the flu virus. This improves elevator air safety and reduces the risk of flu virus transmission. Furthermore, the elevator air conditioner automatically disinfects the air in the elevator, eliminating the need for manual operation by cleaning staff, further reducing the risk of flu transmission.

[0053] According to one embodiment of the present invention, the elevator air conditioner further includes a distance sensor, which is used to detect the optical path distance between the bottom of the elevator and the ultraviolet disinfection device. The step of controlling the ultraviolet disinfection device to disinfect the air in the elevator for a preset time after all people in the elevator leave the elevator also includes:

[0054] S210: Obtain the optical path distance between the bottom of the elevator and the ultraviolet disinfection device.

[0055] S220, adjust the irradiation intensity of the ultraviolet disinfection device according to the light path distance, so that the irradiation intensity at the bottom of the elevator is greater than or equal to the preset irradiation intensity.

[0056] In the embodiment of the application, the ultraviolet disinfection device is installed at the top of the elevator, and the ultraviolet disinfection device emits ultraviolet rays to disinfect the air in the elevator. According to Gauss theorem, when the distance from the light source is close, the irradiation intensity of the ultraviolet rays is high, and the irradiation intensity is inversely proportional to the square of the light path distance. The irradiation intensity at a distance of 1.0 m from the ultraviolet disinfection device is four times the irradiation intensity at a distance of 2.0 m. The height of the elevator is generally about 2.5 m. At this time, the irradiation intensity of the ultraviolet disinfection device at the bottom of the elevator decays quickly, so it is necessary to adjust the irradiation intensity of the ultraviolet disinfection device according to the light path distance between the bottom of the elevator and the ultraviolet disinfection device.

[0057] In steps S210 and S220, the light path distance between the bottom of the elevator and the ultraviolet disinfection device is obtained by the distance sensor, and then the irradiation intensity of the ultraviolet disinfection device is adjusted according to the light path distance. The adjusted irradiation intensity at the bottom of the elevator is greater than or equal to the preset intensity, which can ensure that the viruses carried by the air at the bottom of the elevator are eliminated within a preset time.

[0058] According to an embodiment of the application, the step of obtaining the light path distance between the bottom of the elevator and the ultraviolet disinfection device further comprises:

[0059] S211, obtain the structure information of the elevator, and the structure information at least includes the shape and size of the elevator.

[0060] S212, calculate the maximum light path distance between the corner of the bottom of the elevator and the ultraviolet disinfection device according to the structure information, and take the maximum light path distance as the light path distance for adjusting the irradiation intensity of the ultraviolet disinfection device.

[0061] In step S211, the structure information of the elevator is obtained, and the structure information includes the shape and size of the elevator. According to Gauss principle, the light source is spherical diffusion, and the irradiation intensity on the spherical surface is the same. However, the structure of the elevator is generally rectangular, and the light path distance of the ultraviolet irradiation device to different positions of the bottom of the elevator is different, among which the light path distance of the ultraviolet irradiation device to the vertical bottom of the elevator is the shortest, and the light path distance of the ultraviolet irradiation device to the corner of the top corner of the bottom of the elevator is the longest. In order to ensure that the ultraviolet irradiation device can kill the viruses carried in the air in the whole elevator, it is necessary to ensure that the irradiation intensity at each corner of the elevator is greater than or equal to the preset intensity.

[0062] At step S212, the maximum light path distance between the corner of the bottom inside the elevator and the ultraviolet disinfection device is calculated according to the structural information of the elevator, for example, the distance between the top corner of the bottom inside the elevator and the ultraviolet disinfection device in the horizontal direction is x, the distance in the longitudinal direction is y, and the distance in the vertical direction is z, then the maximum light path distance L 2 = x 2 + y 2 + z 2 Taking the maximum light path distance as the light path distance for adjusting the irradiation intensity of the ultraviolet disinfection device can ensure that the air at the corner inside the elevator remains clean and avoids the situation that sterilization is not in place, thereby reducing the risk of influenza transmission.

[0063] According to an embodiment of the present application, the structural information further includes the light reflectivity of the inner wall of the elevator, and the step of controlling the ultraviolet disinfection device to disinfect the air inside the elevator for a preset time period specifically further includes:

[0064] S230, determining a first compensation coefficient and a second compensation coefficient according to the light reflectivity.

[0065] S240, adjusting the irradiation intensity of the ultraviolet disinfection device by the first compensation coefficient, and adjusting the preset time period according to the second compensation coefficient.

[0066] It can be understood that in order to improve the appearance and cleaning level of the inner wall of the elevator, many inner walls of the elevator adopt a stainless steel mirror surface structure, and the stainless steel mirror surface will have a reflection effect on the ultraviolet light. After the ultraviolet light reaches the stainless steel mirror surface, the light will be reflected, and the reflected ultraviolet light can further increase the disinfection effect on the air, so the emitted light can be fully utilized. With the increase of the light reflectivity of the stainless steel mirror surface, the irradiation intensity of the ultraviolet light at the bottom of the elevator is also enhanced, at this time, the irradiation intensity of the ultraviolet disinfection device or the preset time period of the ultraviolet disinfection device can be reduced to save energy consumption.

[0067] In steps S230 and S240, the first compensation coefficient and the second compensation coefficient can be determined according to the light reflectivity, the irradiation intensity of the ultraviolet disinfection device is adjusted by the first compensation coefficient, and the preset time period is adjusted according to the second compensation coefficient, in the case of ensuring complete sterilization and disinfection inside the elevator, the energy consumption of the elevator air conditioner is reduced as much as possible. Wherein, the light reflectivity is inversely proportional to the first compensation coefficient and the second compensation coefficient, and with the increase of the light reflectivity, the first compensation coefficient and the second compensation coefficient decrease.

[0068] According to an embodiment of the present application, the step of determining the first compensation coefficient according to the light reflectivity specifically includes:

[0069] S231, calculating the first irradiation intensity of the ultraviolet disinfection device at the bottom inside the elevator.

[0070] S232, calculating a second irradiation intensity of the reflected light on the bottom of the elevator according to the light reflectivity.

[0071] S233, determining the first compensation coefficient according to the superposition of the first irradiation intensity and the second irradiation intensity.

[0072] In step S231, the first irradiation intensity is determined according to the Gaussian theorem, the light source intensity of the ultraviolet disinfection device, and the maximum light path distance.

[0073] In step S232, the second irradiation intensity of the reflected light on the bottom of the elevator is calculated according to the light reflectivity. Since the inner wall of the elevator may have multiple stainless steel mirrors, the number of second irradiation intensities may be multiple, and the superposition of multiple second irradiation intensities needs to be calculated.

[0074] In step S233, the first compensation coefficient is determined according to the superposition of the first irradiation intensity and the second irradiation intensity, including determining the maximum irradiation intensity after vector superposition of the first irradiation intensity and multiple second irradiation intensities, and determining the first compensation coefficient according to the maximum irradiation intensity.

[0075] According to one embodiment of the present application, the step of controlling the ultraviolet disinfection device to disinfect the air in the elevator for a preset time after all personnel in the elevator leave the elevator, further comprises:

[0076] S310, in response to the signal that the elevator opens the door at the current floor, the first actual time of the ultraviolet disinfection device disinfecting the air in the elevator is obtained.

[0077] S320, if the first actual time is less than the preset time, the elevator is kept in a closed state until the ultraviolet disinfection device disinfects the air in the elevator for the preset time.

[0078] S330, if the first actual time is greater than or equal to the preset time, the elevator is controlled to open the door at the current floor.

[0079] In step S310, the ultraviolet disinfection device starts to work after all personnel leave the elevator, but the ultraviolet disinfection device needs to run for a preset time before the air in the elevator can be fully disinfected. During the operation of the ultraviolet disinfection device, if there is a person at the current floor calling the elevator to open the door, for example, pressing the up or down button, at this time, it is not clear whether the air in the elevator that has been in contact with the fever patient is completely disinfected, which needs to be judged according to the first actual time of the ultraviolet disinfection device operation.

[0080] In step S320, when the first actual length is less than the preset length, it indicates that the ultraviolet disinfection device is still running at this time, the air in the elevator with risk has not been completely disinfected, and the elevator cannot open the door immediately, but needs to be kept in the closed state until the running length of the ultraviolet disinfection device reaches the preset length, and then the elevator door is opened, so as to ensure that the air in the elevator with risk is completely disinfected.

[0081] In some cases, the ultraviolet disinfection device running can be prompted to the personnel outside the elevator through the prompt component outside the elevator, and the time when the elevator is away from the door can be predicted, so that the anxiety or doubt of the user waiting outside the elevator can be eliminated, and the user can be more reassured.

[0082] In step S330, when the first actual length is greater than or equal to the preset length, it indicates that the running of the ultraviolet disinfection device ends at this time, the air in the elevator with risk is completely disinfected, and the elevator can be opened in response to the door opening signal.

[0083] According to an embodiment of the present application, the step of controlling the ultraviolet disinfection device to disinfect the air in the elevator for a preset length after all the personnel in the elevator leave the elevator further includes:

[0084] S340, in response to a signal that the elevator is called outside the current floor, the elevator is controlled to run to the called floor, and a second actual length of the ultraviolet disinfection device disinfecting the air in the elevator is obtained.

[0085] S350, determining that the second actual length is less than the preset length, the elevator is kept in the closed state until the ultraviolet disinfection device disinfects the air in the elevator for the preset length.

[0086] S360, determining that the second actual length is greater than or equal to the preset length, and controlling the elevator to open the door at the called floor.

[0087] In step S340, the ultraviolet disinfection device starts to work after all the personnel leave the elevator, but the air in the elevator cannot be completely disinfected until the ultraviolet disinfection device runs for a preset length. During the running of the ultraviolet disinfection device, if a personnel outside the current floor calls the elevator to open the door, for example, presses the up or down button, the elevator should run to the called floor according to the calling instruction, but whether the air in the elevator contacting the fever patient is completely disinfected is still unclear, which needs to be judged according to the second actual length of the ultraviolet disinfection device.

[0088] In step S350, when the second actual length is less than the preset length, it indicates that the ultraviolet disinfection device is still running at this time, the air in the elevator with risk has not been completely disinfected, and the elevator cannot open the door immediately, but needs to be kept in the closed state until the running of the ultraviolet disinfection device reaches the preset length, and then the elevator door is opened, so as to ensure that the air in the elevator with risk is completely disinfected.

[0089] In some cases, the personnel outside the elevator can be prompted by the prompt component outside the elevator that the ultraviolet disinfection device is running, while forecasting the time for the elevator to be away from the door, which can eliminate the anxiety or doubt of the waiting users outside the elevator, and make the users more at ease.

[0090] In step S360, when the second actual duration is greater than or equal to the preset duration, it indicates that the ultraviolet disinfection device has ended running, the air in the elevator with risk has been completely disinfected, and the elevator can be opened in response to the door opening signal.

[0091] According to an embodiment of the present application, the elevator air conditioner comprises a microphone component and a plurality of prompt components, and the plurality of prompt components are respectively installed at different positions in the elevator. After determining that the body temperature of the personnel is greater than or equal to the preset temperature, the step further comprises:

[0092] S201, acquiring the noise level in the elevator, the structural information of the elevator, the arrangement information of the prompt components, and the position information of the personnel in the elevator.

[0093] S202, controlling the prompt components to issue prompt information according to the noise level, the structural information, the arrangement information, and the position information.

[0094] It can be understood that during the flu period, the virus spreads widely, on the one hand, the air in the personnel-intensive elevator needs to be disinfected, and on the other hand, the personnel in the elevator also need to be reminded to do well in protection in time to avoid further spread of the flu. For example, after detecting that a feverish personnel enters the elevator, the prompt component issues prompt information in time to remind the feverish personnel to do well in self-protection, and to remind the same-ride personnel to do well in preventive measures.

[0095] When there are many personnel in the elevator or the personnel are noisy, the personnel in the elevator can not pay attention to the prompt information issued by the prompt component, and further spread of the flu can be caused. Therefore, in steps S201 and S202, the prompt components can be controlled to issue prompt information according to the noise level, the structural information, the arrangement information, and the position information. The noise level in the elevator is acquired by the microphone component, when the noise level is large, the personnel in the elevator can not concentrate to acquire the prompt information, and the structural information of the elevator, the arrangement information (including arrangement position and setting direction) of the prompt components, and the position information of the personnel affect the efficiency of the personnel in the elevator to receive the prompt information.

[0096] In step S202, the prompt components can be controlled to issue prompt information according to the arrangement of the elevator structure and the surrounding prompt components where the user is located, and the position of the personnel. The prompt information can be voice broadcast information, or alarm information, etc., such as “high body temperature, pay attention to protection”.

[0097] In some cases, the prompting component includes not only a voice prompting component, but also a display screen, a vibrator, or a flashing light, etc.

[0098] In some embodiments, the step of controlling the prompting component to issue the prompting information according to the noise level, the structure information, the arrangement information, and the position information specifically includes:

[0099] S2021, adjusting the volume and the repetition number of the prompting information issued by the prompting component according to the noise level.

[0100] S2022, determining the prompting component closest to the person in the elevator to issue the prompting information according to the structure information, the arrangement information, and the position information.

[0101] In step S2021, the noise level can be divided into different levels, and the higher the noise level, the louder the prompting information. A linear relationship between the two can also be established to ensure that the volume of the prompting information is always greater than the volume of the noise. At the same time, as the noise level increases, the repetition number of the prompting information can be appropriately increased to improve the possibility of the person obtaining the prompting information.

[0102] In some embodiments, after receiving the prompting information, the person in the elevator determines that there is a fever person in the elevator and the risk of influenza transmission, and the person will remain silent based on safety. At this time, the noise level is reduced to a mute state, indicating that the person in the elevator has obtained the prompting information, which can be used as a sign of whether the prompting information has reached the person.

[0103] In step S2022, according to the structure information of the elevator and the arrangement information of the prompting component and the position information of the person in the elevator (obtained through the biological recognition device), the position of the prompting component closest to the person in the elevator can be determined. By controlling the prompting component to issue the prompting information, it can be ensured that the person accurately receives the prompting information.

[0104] According to one embodiment of the present application, the step of controlling the fan of the elevator air conditioner to stop operating further includes:

[0105] S203, detecting the number of persons in the elevator through the biological recognition device.

[0106] S204, determining that the number of persons is zero, and determining that all the persons in the elevator have left the elevator.

[0107] In steps S203 and S204, the number of persons in the elevator is detected through the biological recognition device arranged in the elevator, so the number of persons can be 0, 1, 2, 3, 4, etc. When all the persons in the elevator have left, the number of persons detected by the biological recognition device in the elevator is 0. At this time, the elevator is closed and the ultraviolet disinfection device is controlled to operate for a preset time period, and the air in the elevator is completely disinfected through the ultraviolet disinfection device.

[0108] According to the second aspect of the present application, the elevator air conditioner comprises a memory, a processor and a computer program stored in the memory and executable on the processor, and the processor implements the steps of the control method of the elevator air conditioner according to the first aspect of the present application when executing the program.

[0109] When the elevator air conditioner is running: in response to the elevator door opening signal, the temperature of the person entering the elevator is obtained; if the temperature of the person is greater than or equal to the preset temperature, the fan of the elevator air conditioner is controlled to stop running, and the ultraviolet disinfection device is controlled to disinfect the air in the elevator for a preset time period after all the persons in the elevator leave the elevator. When the person enters the elevator, the temperature detection device obtains the temperature of the person in time. If the temperature of the person exceeds the preset temperature, for example, 37.3 degrees Celsius, at this time, there is a risk of influenza transmission in the air in the elevator, the fan of the elevator air conditioner is controlled to be turned off in time to slow down the speed of the air flow in the elevator. Secondly, after all the persons in the elevator leave the elevator, the air in the elevator is disinfected in time by the ultraviolet disinfection device, and the disinfection lasts for a preset time period, so as to avoid the subsequent passengers from contacting the air that may carry the influenza virus and reduce the risk of influenza virus transmission, thereby improving the safety of the air in the elevator. Furthermore, the elevator air conditioner automatically realizes the disinfection of the air in the elevator, without the need for manual operation by the cleaning personnel, thereby further reducing the risk of influenza transmission.

[0110] The above only describes the preferred embodiments of the present application and should not be used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
