[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 a fresh air system, which is used to replace the air in the elevator. The fresh air system comprises a fresh air inlet and a fresh air outlet. The fresh air inlet is used to introduce the air outside the elevator into the elevator, and the fresh air outlet is used to blow the air in the elevator out of the elevator. The elevator air conditioner further comprises a temperature detection device and a biological recognition device. The temperature detection device is installed on the top or inner wall of the elevator door opposite to the elevator entrance, 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 , comprising:

[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 first preset temperature, the fan of the elevator air conditioner is controlled to stop running, and the elevator air conditioner is controlled to run in the fresh air mode for the first time length after all the persons in the elevator leave the elevator.

[0050] In step S100, when the elevator stops at the bottom floor or any high floor, the elevator door opening signal is formed when the person presses the up or down button. When the control device of the elevator air conditioner 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 step S200, when the number of people is multiple, the number of body temperatures of the people also has multiple cases, and the body temperature of the people greater than or equal to the first preset temperature means that at least one body temperature of the people is greater than or equal to the first preset temperature, for example, ≥ 37.3 degrees Celsius, at this time, the fan of the elevator air conditioner is controlled to stop running, so as to reduce the air flow speed in the elevator, reduce the spread of influenza virus as much as possible. Secondly, when it is detected that there is a fever in the elevator, the number of people in the elevator is continuously detected by the biological recognition device, and the number of people increases when someone enters the elevator, and the number of people decreases when someone leaves the elevator, so the number of people can be 0, 1, 2, 3, 4…, and the entry and exit of people in the elevator can be represented by 0, ±1, ±2, ±3, ±4, etc. In some cases, only 1 represents that there is someone in the elevator, and 0 represents that all the people in the elevator leave. When it is determined that all the people in the elevator leave the elevator, the elevator air conditioner is controlled to run in the fresh air mode for a first time length, which can be 30 seconds, or can be determined according to the space structure of the elevator and the flow of the fresh air system. The air contacted by the fevered people in the elevator is discharged out of the elevator system through the fresh air system, so as to avoid the subsequent passengers contacting the air that may carry the influenza virus, and improve the safety of the air in the elevator and reduce the risk of transmission of the influenza virus. Further, the elevator air conditioner automatically realizes the renewal and disinfection of the air in the elevator, without the need for manual operation of the cleaning personnel, and further reduces the risk of influenza transmission.

[0052] It should be noted that the fresh air outlet of the fresh air system in the embodiment of the application is arranged to face the outdoor, for example, the roof or the side away from the inside of the community, so as to avoid the discharged air contacting the people. In some cases, a disinfection module is arranged at the fresh air outlet or in the exhaust pipe of the fresh air system, for example, an ultraviolet disinfection module, a high-temperature disinfection module or a disinfectant spraying module.

[0053] In some embodiments, the step of controlling the elevator air conditioner to run in the fresh air mode for the first time length after all the people in the elevator leave the elevator specifically includes:

[0054] S210, detecting the number of people in the elevator by the biological recognition device.

[0055] S220, determining that the number of people is zero, determining that all the people in the elevator leave the elevator, and then controlling the elevator air conditioner to run in the fresh air mode for a first time length.

[0056] In step S210, the number of people in the elevator is detected by the biometric identification device arranged in the elevator, so the number of people can be 0, 1, 2, 3, 4, etc. When all the people in the elevator leave, the biometric identification device detects that the number of people in the elevator is 0, at which time the elevator is closed and the elevator air conditioner is controlled to run in the fresh air mode for a first duration, and the air in the elevator is completely discharged through the fresh air system.

[0057] In some embodiments, the step of controlling the elevator air conditioner to run in the fresh air mode for the first duration further includes:

[0058] S300, in response to a signal that the elevator opens the door at the current floor, the first actual duration of the fresh air mode of the elevator air conditioner is obtained.

[0059] S310, if the first actual duration is less than the first duration, the elevator is kept in a closed state until the fresh air mode of the elevator air conditioner reaches the first duration.

[0060] S320, if the first actual duration is greater than or equal to the first duration, the elevator is controlled to open the door at the current floor.

[0061] In step S300, the fresh air system starts to work after all the people leave the elevator, but the fresh air system needs to run for a first duration before the air in the elevator is completely discharged. During the operation of the fresh air system, if a person at the current floor calls the elevator to open the door, for example, presses the up or down button, it is not clear whether the air in the elevator that has been in contact with the fever patient has been completely discharged, which needs to be judged according to the first actual duration of the fresh air mode of the elevator air conditioner.

[0062] In step S310, when the first actual duration is less than the first duration, it means that the fresh air mode is still running at this time, and the air with risk in the elevator has not been completely discharged, so the elevator cannot be immediately opened, but is kept in a closed state until the fresh air mode of the elevator air conditioner reaches the first duration, and then the elevator door is opened to ensure that the air with risk in the elevator is completely discharged.

[0063] In some cases, a prompt component outside the elevator can be used to prompt the person outside the elevator that the fresh air mode is running, and the time when the elevator will open the door can be predicted, which can eliminate the anxiety or doubt of the waiting user outside the elevator, and make the user more at ease.

[0064] In step S320, when the first actual duration is greater than or equal to the first duration, it means that the fresh air mode is running at this time, and the air with risk in the elevator has been completely discharged, so the elevator can open the door in response to the opening signal.

[0065] In some embodiments, the step of controlling the elevator air conditioner to run in the fresh air mode for the first duration further includes:

[0066] S330, in response to the signal that the elevator is called outside the current floor, controlling the elevator to run to the called floor, and obtaining a second actual time length of running the fresh air mode of the elevator air conditioner when the elevator air conditioner runs to the called floor.

[0067] S340, determining that the second actual time length is less than the first time length, and keeping the elevator in the closed door state until the fresh air mode of the elevator air conditioner runs for the first time length.

[0068] S350, determining that the second actual time length is greater than or equal to the first time length, and controlling the elevator to open the door at the called floor.

[0069] In step S330, the fresh air system starts to work after all the people in the elevator leave, but the fresh air system needs to run for a first time length before the air in the elevator is completely discharged. During the running of the fresh air system, if a person 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 it is not clear whether the air in the elevator that has contacted the fever patient has been completely discharged or not, which needs to be judged according to the second actual time length of the fresh air mode of the elevator air conditioner.

[0070] In step S340, when the second actual time length is less than the first time length, it means that the fresh air mode is still running at this time, and the risky air in the elevator has not been completely discharged, so the elevator cannot open the door immediately, but needs to be kept in the closed door state until the fresh air mode of the elevator air conditioner runs for the first time length, and then the elevator door is opened to ensure that the risky air in the elevator is completely discharged.

[0071] In some cases, the personnel outside the elevator can be prompted by a prompt component outside the elevator that the fresh air mode is running, and the time when the elevator will open the door can be predicted, which can eliminate the anxiety or doubt of the waiting user outside the elevator, and make the user more at ease.

[0072] In step S350, when the second actual time length is greater than or equal to the first time length, it means that the fresh air mode has ended at this time, and the risky air in the elevator has been completely discharged, so the elevator can open the door in response to the door opening signal.

[0073] In some embodiments, the step of controlling the elevator air conditioner to run the fresh air mode for a first time length after all the people in the elevator leave further includes:

[0074] S230, in response to the elevator closed door signal, obtaining a third actual time length after the elevator is closed.

[0075] S240, controlling the elevator air conditioner to run the fresh air mode according to the third actual time length and a preset period.

[0076] When the elevator is in standby state for a long time without passengers, the elevator air conditioner can be in shutdown or standby state in order to save energy, and the air in the elevator cannot be replaced and freshened during this period.

[0077] In step S230 and step S240, after the elevator door is closed, the third actual time length of the elevator door closing is obtained, and the elevator air conditioner is controlled to run the fresh air mode according to the third actual time length and the preset period. The preset period can be 4 hours, or other time length set by human. When the third actual time length is greater than the preset period, the elevator air conditioner starts and runs the fresh air mode for a period of time. When the third actual time length is greater than 8 hours, the preset period is reached again, and the elevator air conditioner is controlled to run the fresh air mode again, that is, the fresh air mode is run every time the preset period is reached, to ensure that the air in the elevator is fresh.

[0078] In some embodiments, the elevator air conditioner includes a microphone assembly and a plurality of prompt assemblies installed at different positions in the elevator. After determining that the body temperature of the person is greater than or equal to the first preset temperature, the method further includes:

[0079] S250, obtaining the noise level in the elevator, the structural information of the elevator, the arrangement information of the prompt assembly, and the position information of the person in the elevator.

[0080] S260, controlling the prompt assembly to send prompt information according to the noise level, the structural information, the arrangement information, and the position information.

[0081] It can be understood that during the flu period, the virus spreads widely. On the one hand, the air in the elevator with a large number of people needs to be replaced and disinfected, and on the other hand, the people in the elevator need to be reminded to take preventive measures to avoid further spread of the flu. For example, after detecting that a feverish person enters the elevator, the prompt assembly sends prompt information in time to remind the feverish person to take self-protection measures, and to remind the same passengers to take preventive measures.

[0082] When there are many people in the elevator or the voices of the people are loud, the people in the elevator can not pay attention to the prompt information sent by the prompt assembly, which can further spread the flu. Therefore, in step S250 and step S260, the prompt assembly can send prompt information according to the noise level, the structural information, the arrangement information, and the position information. The noise level in the elevator is obtained through the microphone assembly. When the noise level is high, the people in the elevator can not concentrate to obtain the prompt information. The structural information of the elevator, the arrangement information of the prompt assembly (including the arrangement position and the setting direction), and the position information of the people affect the efficiency of the people in the elevator receiving the prompt information.

[0083] In step S260, the prompting component can be controlled to issue a prompt message according to the elevator structure in which the user is located, the arrangement of the surrounding prompting components, and the position of the personnel. The prompt message can be a voice broadcast message or an alarm message, for example, "high temperature, pay attention to protection".

[0084] In some cases, the prompting component not only includes a voice prompting component, but also includes a display screen, a vibrator, or a flashing light, etc.

[0085] In some embodiments, the step of controlling the prompting component to issue the prompt message according to the noise level, the structure information, the arrangement information, and the position information specifically includes:

[0086] S261, adjusting the volume and the repetition number of the prompt message issued by the prompting component according to the noise level.

[0087] S262, determining the prompting component closest to the personnel in the elevator to issue the prompt message according to the structure information, the arrangement information, and the position information.

[0088] In step S261, the noise level can be divided into different levels. The higher the noise level, the louder the volume of the prompt message. A linear relationship between the two can also be established to ensure that the volume of the prompt message is always greater than the volume of the noise. At the same time, as the noise level increases, the repetition number of the prompt message can be appropriately increased to improve the possibility of personnel obtaining the prompt message.

[0089] In some embodiments, after receiving the prompt message, the personnel in the elevator determine that there is a fever personnel in the elevator and the risk of influenza transmission. The personnel will remain silent based on safety. At this time, the noise level is reduced to a mute state, indicating that the personnel in the elevator have obtained the prompt message, which can be used as a sign of whether the prompt message has been delivered.

[0090] In step S262, the position of the prompting component closest to the personnel in the elevator can be determined according to the structure information of the elevator, the arrangement information of the prompting component, and the position information of the personnel in the elevator (obtained through the biological recognition device). By controlling the prompting component to issue the prompt message, it can be ensured that the personnel accurately receive the prompt message.

[0091] In some embodiments, the fresh air inlet of the elevator air conditioner is provided with a first temperature sensor, and the fresh air outlet of the elevator air conditioner is provided with a second temperature sensor. The step of controlling the elevator air conditioner to run in the fresh air mode for a first duration after all the personnel in the elevator leave the elevator further includes:

[0092] S400, in response to the instruction to run in the fresh air mode, obtaining the first temperature of the fresh air inlet and the second temperature of the fresh air outlet.

[0093] S410, adjust the first time length in real time according to the difference between the first temperature and the second temperature.

[0094] In the embodiment of the present application, the elevator air conditioner comprises a fresh air system, the fresh air system comprises a fresh air inlet and a fresh air outlet, the fresh air inlet is provided with a first temperature sensor, the first temperature sensor is used to obtain the outdoor air temperature, the fresh air outlet is provided with a second temperature sensor, and the second temperature sensor is used to obtain the air temperature discharged from the elevator. Due to the differences in the environmental temperature, sunlight, wind speed and the like inside and outside the elevator, the air temperature inside the elevator and the air temperature outside the elevator are different. When the fresh air system is working, the outdoor air is continuously introduced into the elevator, and the air inside the elevator is continuously blown out of the elevator, then with the gradual replacement of the air inside the elevator, the first temperature and the second temperature tend to be the same, which indicates that the fresh air replacement in the elevator is completed at this time, and therefore the specific time length of the first time length of the elevator air conditioner running in the fresh air mode can be determined according to the first temperature and the second temperature.

[0095] In step S400 and step S410, after responding to the instruction of running the fresh air mode, the first temperature of the fresh air inlet and the second temperature of the fresh air outlet are obtained, the difference between the first temperature and the second temperature is determined, and when the difference approaches 0 or meets the preset temperature, it can be confirmed that the fresh air replacement is completed, and therefore the length of the first time length can be determined.

[0096] In some embodiments, the step of adjusting the first time length in real time according to the difference between the first temperature and the second temperature specifically comprises:

[0097] S411, calculate the difference between the first temperature and the second temperature, and record the time corresponding to the difference.

[0098] S412, determine whether the difference is greater than or equal to a second preset temperature, if yes, control the elevator air conditioner to continue running in the fresh air mode for a second time length, and repeat the above steps after running for the second time length.

[0099] S413, determine whether the difference is less than the second preset temperature, and whether the duration that the difference is less than the second preset temperature is greater than or equal to a third time length, if yes, take the time when the duration is equal to the third time length as the termination time of the first time length.

[0100] In step S411, the first temperature and the second temperature are continuously obtained, and the difference between the first temperature and the second temperature is calculated in real time, and the time corresponding to the difference is recorded, the difference and the time can determine the change of the difference with time.

[0101] In step S412, when the difference is greater than or equal to the second preset temperature, it indicates that the air temperature inside and outside the elevator is greatly different, and the fresh air replacement in the elevator is not complete. At this time, the duration of the fresh air mode is temporarily increased by a second duration, for example, 10 seconds. After 10 seconds, the relationship between the difference and the second preset temperature is determined again, and the above steps are repeated, and the unit duration is increased by 10 seconds each time, until the difference is less than the second preset temperature. In some cases, the second preset temperature is 0.5 degrees Celsius.

[0102] In step S413, when the difference is less than the second preset temperature, it indicates that the temperature of the air discharged from the elevator and the temperature of the air sucked in are similar, and the fresh air replacement in the elevator is complete. If the duration when the difference is less than the second preset temperature is greater than or equal to a third duration, for example, 10 seconds, it can be confirmed that the fresh air replacement in the elevator is complete and in a stable state at this time, and the time point when the duration is equal to the third duration is taken as the termination time point of the first duration.

[0103] 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. When the processor executes the program, the steps of the control method of the elevator air conditioner according to the first aspect of the present application are implemented.

[0104] The elevator air conditioner comprises a temperature detection device and a biological recognition device. The temperature detection device is arranged corresponding to the elevator entrance, and the biological recognition device is used to detect the number of personnel in the elevator and the personnel in and out. When the elevator air conditioner is running: in response to an elevator door opening signal, the body temperature of the personnel entering the elevator is obtained; if the body temperature of the personnel is greater than or equal to a first preset temperature, the fan of the elevator air conditioner is controlled to stop running, and the elevator air conditioner is controlled to run in a fresh air mode for a first duration after all the personnel in the elevator leave the elevator. When the personnel enter the elevator, the temperature detection device obtains the body temperature of the personnel in time. If the body temperature of one of the personnel exceeds the first preset temperature, for example, 37.3 degrees Celsius, there is a risk of influenza transmission at this time, and the fan of the elevator air conditioner is controlled to be turned off in time to slow down the speed of air flow in the elevator. Secondly, after the personnel in the elevator leave the elevator, the air in the elevator is replaced in time through the fresh air system of the elevator air conditioner, so as to avoid the subsequent passengers from contacting the air that may carry the influenza virus, improve the safety of the air in the elevator, and reduce the risk of influenza virus transmission. Furthermore, the elevator air conditioner automatically realizes the renewal and disinfection of the air in the elevator, without manual operation by cleaning personnel, and further reduces the risk of influenza transmission.

[0105] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
