Fig. 1 is a flowchart of a sterilizing method of an air conditioner according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
Step S101, acquiring the refrigerating operation time of an air conditioner, wherein the refrigerating operation time refers to the duration of the air conditioner in a refrigerating mode;
specifically, the refrigerating operation time length refers to the time of one continuous refrigeration of the air conditioner, for example, 2:00 starts to refrigerate and 2:30 ends, and then the time of the refrigeration is 30min; for example, 3:00 starts to refrigerate and 3:20 ends, then the time of this refrigeration is 20min; i.e. a time in which the duration is not intermittent.
Further, from the start of the power-on of the air conditioner, a period of time is required to start the cooling, and the timing is started after the cooling starts.
Step S102, determining whether the air conditioner meets the refrigeration requirement or not at least according to the pipe temperature of the outdoor heat exchanger under the condition that the refrigeration operation time length is greater than or equal to a first preset time length, wherein the refrigeration requirement comprises that the heat exchange efficiency of the outdoor heat exchanger is higher than a preset heat exchange efficiency;
specifically, the first preset duration may be selected to be 10min, 15min, 20min, etc., and a person skilled in the art may adjust the first preset duration according to actual conditions, and only if the length of the cooling operation is greater than or equal to the first preset duration, it is determined whether the air conditioner meets the cooling requirement according to at least the outdoor heat exchanger tube temperature, where the reason set by the precondition that the length of the cooling operation is greater than or equal to the first preset duration is: when the whole machine receives a starting instruction, the compressor is started relatively late, the frequency rising is a process, the length of the refrigerating operation time is set to be longer than or equal to the first preset time length, firstly, a good cooling effect in a room can be ensured, secondly, whether the whole machine is abnormal can be judged, and if the whole machine is abnormal, the temperature change of each temperature sensing element is obvious, so that the follow-up logic execution is facilitated.
Specifically, the preset heat exchange efficiency can be selected to be 90%, 85%, 80% or the like, and the skilled person can select according to actual conditions. Namely, under the condition that the heat exchange condition of the outdoor heat exchanger is good, the higher refrigeration requirement of the air conditioner can be met, and the subsequent sterilization step is facilitated.
It should be noted that factors affecting the heat exchange efficiency of the outdoor heat exchanger include: whether the pipeline of the outdoor heat exchanger is dirty and blocked, whether the pipeline of the outdoor heat exchanger is cracked, and the like.
Specifically, "determining whether the air conditioner meets the refrigeration requirement based at least on the outdoor heat exchanger tube temperature" includes determining whether the air conditioner meets the refrigeration requirement based only on the outdoor heat exchanger tube temperature, and also includes determining whether the air conditioner meets the refrigeration requirement based on the "outdoor heat exchanger tube temperature" and other factors;
Step S103, determining whether to enter a high-temperature sterilization mode according to the indoor environment temperature under the condition that the air conditioner meets the refrigeration requirement.
In step S103, when the cooling requirement is satisfied, a step of determining whether to start the high-temperature sterilization according to the information such as the indoor environment temperature is further required.
In the scheme, by acquiring the refrigerating operation time length of the air conditioner, under the condition that the refrigerating operation time length is greater than or equal to the first preset time length, whether the air conditioner meets the refrigerating requirement is determined at least according to the pipe temperature of the outdoor heat exchanger, and under the condition that the air conditioner meets the refrigerating requirement, whether the air conditioner enters a high-temperature sterilization mode is determined according to the indoor environment temperature. By adopting the scheme, the high-temperature sterilization is realized, and the refrigerating comfort is ensured.
In an alternative embodiment, step S102: under the condition that the length of the refrigerating operation time is longer than or equal to the first preset time length, whether the air conditioner meets the refrigerating requirement or not is determined at least according to the tube temperature of the outdoor heat exchanger, and the refrigerating operation method comprises the following two implementation modes: the first implementation mode: determining whether the air conditioner meets the refrigeration requirement according to the outdoor environment temperature and the pipe temperature of the outdoor heat exchanger; i.e. comprehensively considering the outdoor environment temperature and the pipe temperature of the outdoor heat exchanger to determine whether the refrigeration requirement is met; the second implementation mode: and determining whether the air conditioner meets the refrigeration requirement according to the pipe temperature of the outdoor heat exchanger. I.e. determination of whether the refrigeration demand is met may also be accomplished based solely on the outdoor heat exchanger tube temperature determination.
In a specific embodiment, for the first implementation: determining whether the air conditioner meets the refrigeration requirement according to the outdoor environment temperature and the outdoor heat exchanger tube temperature, comprising the following steps: step S1021: acquiring a first temperature difference, wherein the first temperature difference refers to a difference between the outdoor environment temperature and the outdoor heat exchanger tube temperature; step S1022: and determining that the air conditioner meets the refrigeration requirement under the condition that the first temperature difference value is larger than or equal to a first difference value threshold value and smaller than or equal to a second difference value threshold value. Specifically, the first difference threshold and the second difference threshold can be obtained according to actual test, and a person skilled in the art can adjust according to actual requirements, so as to ensure accuracy of the first difference threshold and the second difference threshold, and further ensure accuracy of determining whether the air conditioner meets refrigeration requirements.
In a specific embodiment, for the second implementation: determining whether the air conditioner meets the refrigeration requirement only according to the pipe temperature of the outdoor heat exchanger can be realized as follows: and determining that the air conditioner meets the refrigeration requirement under the condition that the pipe temperature of the outdoor heat exchanger is greater than or equal to a first temperature threshold value and less than or equal to a second temperature threshold value. That is, under the condition that only the temperature of the outdoor heat exchanger tube is considered, whether the temperature of the outdoor heat exchanger tube falls into a range from a first temperature threshold value to a second temperature threshold value or not can be determined according to the fact that the first temperature threshold value and the second temperature threshold value can be obtained according to actual test tests, and a person skilled in the art can adjust according to actual requirements so as to ensure accuracy of the first temperature threshold value and the second temperature threshold value and further ensure accuracy of determining whether the air conditioner meets refrigeration requirements or not.
In an alternative embodiment, step S103: under the condition that the air conditioner meets the refrigerating requirement, determining whether to enter a high-temperature sterilization mode according to the indoor environment temperature comprises the following steps:
step S1031: determining whether the indoor environment temperature is less than or equal to a third temperature threshold value in real time;
Step S1032: determining whether at least one of the following is satisfied in a case where the indoor environmental temperature is less than or equal to the third temperature threshold value: whether the absolute value of the second difference value is smaller than a third difference value threshold value and whether the temperature drop rate is larger than or equal to a preset rate, wherein the second difference value refers to the difference value between the indoor preset temperature and the indoor environment temperature, and the temperature drop rate refers to the ratio of the difference value between the indoor environment temperature at the current moment and the indoor environment temperature at the power-on moment to the refrigerating operation duration at the current moment;
step S1033: and if so, determining to enter the high-temperature sterilization mode.
Specifically, the third temperature threshold, the third difference threshold and the preset speed can be obtained according to actual test, and a person skilled in the art can adjust according to actual requirements to ensure the accuracy of the third temperature threshold, the third difference threshold and the preset speed so as to realize accurate control on whether the air conditioner enters a high-temperature sterilization mode or not, and further ensure the accuracy of determining whether the air conditioner meets the refrigeration requirement or not.
In the above-mentioned scheme, after meeting the refrigeration requirement, it is further required to determine whether to enter the high-temperature sterilization mode according to the indoor environment temperature, the difference between the indoor preset temperature and the indoor environment temperature, and the temperature drop rate. So as to realize the accurate control of the threshold for determining to enter the high-temperature sterilization mode.
In some embodiments, at step S1032: when the indoor environmental temperature is less than or equal to the third temperature threshold, determining whether at least one of the following is satisfied: after whether the absolute value of the second difference is smaller than a third difference threshold and whether the temperature drop rate is greater than or equal to a preset rate, the method further includes: and if the temperature of the outdoor heat exchanger is not met, determining whether to enter the high-temperature sterilization mode at least according to the pipe temperature of the outdoor heat exchanger at the current moment. That is, if the above condition is not satisfied, it may be further determined whether to enter the high temperature sterilization mode according to the outdoor heat exchanger tube temperature at the current time. So as to realize accurate determination of whether to enter the high-temperature sterilization mode.
In a more specific embodiment, if the temperature of the outdoor heat exchanger tube at the current moment is not satisfied, determining whether to enter the high-temperature sterilization mode at least according to the temperature of the outdoor heat exchanger tube at the current moment includes two implementation methods: the first way is: under the condition of unsatisfied condition, determining whether to enter the high-temperature sterilization mode according to the outdoor environment temperature at the current moment and the pipe temperature of the outdoor heat exchanger at the current moment; the second way is: if not, determining whether to enter the high-temperature sterilization mode according to the pipe temperature of the outdoor heat exchanger. That is, if it is not satisfied that the absolute value of the second difference is less than the third difference threshold and the temperature drop rate is greater than or equal to at least one of the preset rates, it is determined whether to enter the above-described high temperature sterilization mode according to the outdoor ambient temperature at the present time and the outdoor heat exchanger tube temperature at the present time, or whether to enter the above-described high temperature sterilization mode only according to the outdoor heat exchanger tube temperature. The absolute value of the second difference value is smaller than the third difference value threshold value or the temperature drop rate is larger than or equal to the preset rate, which indicates that the temperature drop of the room is faster, the heat dissipation of the room temperature is less, and the heat preservation capability is better.
Specifically, the first mode: under the condition that the high-temperature sterilization mode is not met, determining whether to enter the high-temperature sterilization mode according to the outdoor environment temperature at the current moment and the outdoor heat exchanger tube temperature at the current moment, and comprising the following steps: acquiring a second temperature difference value, wherein the second temperature difference value refers to a difference value between the outdoor environment temperature at the current moment and the tube temperature of the outdoor heat exchanger at the current moment; and under the condition that the second temperature difference value is smaller than a fourth difference value threshold value, determining to enter the high-temperature sterilization mode. That is, in the case where "the absolute value of the second difference is less than the third difference threshold value, the temperature drop rate is greater than or equal to at least one of the preset rates" is not satisfied, it is determined whether to enter the high-temperature sterilization mode according to the difference between the outdoor ambient temperature at the present time and the tube temperature of the outdoor heat exchanger at the present time.
