[0020] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0021] Figure 1 It is a flow chart of a control method of a fresh air air conditioner proposed in an embodiment of the present disclosure.

[0022] This embodiment takes the control method of the fresh air air conditioner as an example in which the control method is configured in the control device of the fresh air air conditioner. In this embodiment, the control method of the fresh air air conditioner can be configured in the control device of the fresh air air conditioner. The control device of the fresh air air conditioner can be set in a server, or can also be set in an electronic device, without limitation. This embodiment takes the control method of the fresh air air conditioner as an example in which the control method is configured in an electronic device. Among them, electronic devices such as smart phones, tablet computers, personal digital assistants, e-books, and other hardware devices with various operating systems.

[0023] It should be noted that the execution subject of the embodiments of the present disclosure may be, for example, a central processing unit (CPU) in a server or electronic device in terms of hardware, or may be, for example, a related background service in a server or electronic device in terms of software, without limitation.

[0024] like Figure 1 As shown, the control method of the fresh air air conditioner includes:

[0025] S101: Receive an on request instruction, wherein the on request instruction is used to request to turn on a fresh air function of a fresh air air conditioner.

[0026] In some embodiments, a request instruction for requesting to turn on the fresh air function of the fresh air air conditioner may be referred to as a turn-on request instruction.

[0027] In some embodiments, the turn-on request instruction can be triggered by a user. For example, when a user operates the fresh air function button on the air conditioner remote control, the remote control transmits the turn-on request instruction to the control device of the fresh air air conditioner. The control device of the fresh air air conditioner can receive the turn-on request instruction and determine that the turn-on request instruction is used to request to turn on the fresh air function of the fresh air air conditioner.

[0028] In some embodiments, after receiving the start request instruction, the fresh air function may not be triggered temporarily, and then a suitable time to start the fresh air function is determined based on the method provided in the embodiment of the present disclosure.

[0029] In some embodiments, if it is determined that it is a suitable time to turn on the fresh air function, the fresh air function can be triggered to turn on. If it is determined that it is not a suitable time to turn on the fresh air function, the fresh air function may not be triggered and dynamic detection may be performed until the suitable time to turn on the fresh air function is determined.

[0030] In some embodiments, receiving an activation request instruction triggers determination of an appropriate time to activate the fresh air function, so that activation of the fresh air function meets the user's intention to use the fresh air function, thereby improving the user experience.

[0031] S102: Determine the number of times the outdoor ambient temperature changes between a first temperature interval and a second temperature interval, wherein the first temperature interval and the second temperature interval are different.

[0032] In some embodiments, the outdoor ambient temperature may be detected, and the temperature range of the outdoor ambient temperature may be determined, and the number of times the outdoor ambient temperature changes between the first temperature range and the second temperature range may be determined.

[0033] In some embodiments, the outdoor ambient temperature can be detected based on the following method: the main board of the fresh air air conditioner outdoor unit transmits a sampling signal after sampling, the sampled signal is deeply filtered, and the average is calculated after sampling 32 times. The filtering depth in different situations can be determined according to the actual required control rate (the control rate can be, for example, the control response efficiency of the fresh air air conditioner). After the filtering is completed, analog-to-digital conversion is performed to obtain the accurate outdoor ambient temperature.

[0034] In some embodiments, the outdoor ambient temperature may be detected dynamically and continuously, and the temperature interval of the outdoor ambient temperature may be determined to assist in determining the number of interval changes between the first temperature interval and the second temperature interval.

[0035] In some embodiments, after receiving the start request instruction, the number of times the outdoor ambient temperature changes between the first temperature range and the second temperature range can be determined, and the subsequent determination of whether to turn on the fresh air function based on the number of interval changes can be triggered.

[0036] In some embodiments, the first temperature interval and the second temperature interval are different, that is, the first temperature interval and the second temperature interval include different temperature values.

[0037] In some embodiments, the first temperature interval may be, for example, a temperature interval between a first temperature value and a second temperature value, the second temperature interval may be, for example, a temperature interval less than the first temperature value, or the second temperature interval may be, for example, a temperature interval greater than the second temperature value.

[0038] In some embodiments, the first temperature interval may be, for example, a temperature interval that triggers turning on the fresh air function, and the second temperature interval may be, for example, a temperature interval that triggers turning off the fresh air function.

[0039] In some embodiments, the first temperature value may be between -20 degrees Celsius (°C) and 0°C, and the second temperature value may be between 50°C and 60°C.

[0040] In some embodiments, the first temperature value may be -10°C, and the second temperature value may be 53°C.

[0041] In some embodiments, the first temperature interval is, for example, a temperature interval between -10°C and 53°C, the second temperature interval may be, for example, a temperature interval less than -10°C, and the second temperature interval may also be, for example, a temperature interval greater than 53°C.

[0042] In some embodiments, the lower limit temperature of the outdoor ambient temperature that triggers the fresh air function to be turned on can also be determined, and the upper limit temperature of the outdoor ambient temperature that triggers the fresh air function to be turned on can be determined, and the temperature interval between greater than or equal to the lower limit temperature and less than or equal to the upper limit temperature can be used as the first temperature interval, the temperature interval less than the lower limit temperature can be used as the second temperature interval, and / or the temperature interval greater than the upper limit temperature can be used as the second temperature interval. When the fresh air air conditioner is controlled based on the determined first temperature interval and second temperature interval, it can support improving the accuracy of determining the timing of turning on the fresh air function.

[0043] In some embodiments, the lower limit temperature of the outdoor ambient temperature that triggers the fresh air function to be turned on means that when the outdoor ambient temperature is detected to reach the lower limit temperature (for example, greater than or equal to the lower limit temperature), the fresh air function is triggered to be turned on. The upper limit temperature of the outdoor ambient temperature that triggers the fresh air function to be turned on means that when the outdoor ambient temperature is detected to reach the upper limit temperature (for example, less than or equal to the upper limit temperature), the fresh air function is triggered to be turned on.

[0044] In some embodiments, if it is detected that the outdoor ambient temperature does not reach the lower limit temperature (for example, is lower than the lower limit temperature), or it is detected that the outdoor ambient temperature is not lower than the upper limit temperature (for example, is higher than the upper limit temperature), the fresh air function may not be triggered.

[0045] The method provided by the embodiment of the present disclosure can determine the number of times the outdoor ambient temperature changes between the first temperature interval and the second temperature interval. For example, the outdoor ambient temperature can be dynamically detected, and it can be determined whether the outdoor ambient temperature is in the first temperature interval or the second temperature interval. If the outdoor ambient temperature is in the first temperature interval, then during the dynamic detection process, if it is determined that the outdoor ambient temperature changes from the first temperature interval to the second temperature interval, the number of interval changes can be accumulated. Correspondingly, if it is determined that the outdoor ambient temperature changes from the second temperature interval back to the first temperature interval, the number of interval changes can be further accumulated.

[0046] S103: Determine whether to turn on the fresh air function according to the number of interval changes.

[0047] In some embodiments, when the fresh air function was determined and turned on last time, the number of interval changes can be started to be counted. When the turn-on request instruction is received this time, the number of interval changes of the outdoor ambient temperature obtained by the current count between the first temperature interval and the second temperature interval is determined, and based on the number of interval changes, it is determined whether to turn on the fresh air function.

[0048] In some embodiments, if the number of interval changes is large, it means that the fresh air function has been frequently switched between on and off, and the fresh air effect is poor. If this state is maintained for a long time, the indoor air will not be fresh. If the number of interval changes is small, it means that the fresh air function is not switched frequently. Therefore, in the embodiments of the present disclosure, the number of interval changes can be referred to to determine whether to respond to the start request instruction, that is, to determine whether to turn on the fresh air function this time.

[0049] In some embodiments, the number of interval changes can be input into the judgment model to determine whether to turn on the fresh air function based on the judgment model. Alternatively, reference data can be obtained from the cloud, such as reference times and whether the fresh air function is turned on under the corresponding reference times. The number of interval changes is compared with the reference times to determine whether the fresh air function is turned on this time. Alternatively, any other possible method can be combined to determine whether to turn on the fresh air function based on the number of interval changes, and there is no limitation on this.

[0050] In this embodiment, by receiving a turn-on request instruction, wherein the turn-on request instruction is used to request to turn on the fresh air function of the fresh air air conditioner, and determining the number of times the outdoor ambient temperature changes between a first temperature range and a second temperature range, wherein the first temperature range and the second temperature range are different, and determining whether to turn on the fresh air function based on the number of interval changes, the timing of turning on the fresh air function can be accurately determined, thereby effectively avoiding affecting the indoor temperature control effect.

[0051] Figure 2 It is a flow chart of a control method for a fresh air air conditioner proposed in another embodiment of the present disclosure.

[0052] like Figure 2 As shown, the control method of the fresh air air conditioner includes:

[0053] S201: Receive an on request instruction, wherein the on request instruction is used to request to turn on a fresh air function of the fresh air air conditioner.

[0054] S202: Determine the number of times the outdoor ambient temperature changes between a first temperature interval and a second temperature interval, wherein the first temperature interval and the second temperature interval are different.

[0055] For the description of S201 - S202 , please refer to the above embodiment, which will not be repeated here.

[0056] S203: If the number of interval changes is greater than the number threshold, it is determined to turn on the fresh air function.

[0057] In some embodiments, the number threshold may refer to a threshold value for determining the number of interval changes for turning on the fresh air function.

[0058] In some embodiments, the number threshold may also be, for example, a threshold of the number of switching times indicating that the fresh air function has been frequently switched between on and off.

[0059] In some embodiments, the number threshold may be, for example, any number between 5 and 20 times, such as 5 times or 20 times.

[0060] In some embodiments, the number threshold may be, for example, 10 times.

[0061] In some embodiments, the number of interval changes may be compared with a number threshold, and whether to turn on the fresh air function may be determined based on the comparison result.

[0062] In some embodiments, if the number of interval changes is greater than the number threshold, it means that the fresh air function has been frequently switched between on and off. At this time, it can be determined that the fresh air effect is poor. If this state is maintained for a long time, the indoor air will not be fresh. Therefore, it can be directly determined to turn on the fresh air function.

[0063] S204: If the number of interval changes is less than or equal to the number threshold, determine a first duration for which the outdoor ambient temperature is in the second temperature interval.

[0064] In some embodiments, if the number of interval changes is less than or equal to the number threshold, it means that the fresh air function is not switched frequently. At this time, in order to accurately determine whether it is time to turn on the fresh air function, other contents may be further referred to for determination.

[0065] In some embodiments, a first duration that the outdoor ambient temperature is in the second temperature range may be determined, and the first duration may be used to determine whether to turn on the fresh air function.

[0066] In some embodiments, the second temperature interval may be, for example, a temperature interval that triggers shutting down of the fresh air function.

[0067] In some embodiments, the duration that the outdoor ambient temperature was in the second temperature range at least once when the fresh air function was turned on last time is determined, and the duration that the outdoor ambient temperature was in the second temperature range at least once is accumulated to obtain the first duration, thereby improving the reference value of the duration that the outdoor ambient temperature was in the second temperature range to support determining the appropriate time to turn on the fresh air function.

[0068] In some embodiments, if the outdoor environment temperature is in the second temperature interval only once, the duration of the time when the outdoor environment temperature is in the second temperature interval may be directly used as the first duration.

[0069] In some embodiments, the outdoor ambient temperature may be in the second temperature interval for multiple times, and the duration of each time being in the second temperature interval may be detected, and the durations of multiple times being in the second temperature interval may be accumulated to obtain the first duration.

[0070] In some embodiments, if the number of interval changes is less than or equal to the number threshold, when it is detected that the outdoor ambient temperature has an interval change between the first temperature interval and the second temperature interval, the number of interval changes is increased by one until the number of interval changes reaches the number threshold, thereby realizing dynamic monitoring of the number of interval changes to improve the continuity of the fresh air air conditioning control effect.

[0071] S205: Determine whether to turn on the fresh air function based on the first duration.

[0072] In some embodiments, if the outdoor ambient temperature is in the second temperature range for a long period of time, it can be determined that the fresh air function is in the off state for a long time; if the outdoor ambient temperature is in the second temperature range for a short period of time, it can be determined that the fresh air function is not in the off state for a long time.

[0073] In some embodiments, if the fresh air function is turned off for a long time, the indoor air may become stale. Therefore, in the embodiments of the present disclosure, it is also possible to determine whether to turn on the fresh air function by referring to the first duration that the outdoor ambient temperature is in the second temperature range.

[0074] In some embodiments, the first duration can be input into the judgment model to determine whether to turn on the fresh air function based on the judgment model. Alternatively, reference data can be obtained from the cloud, such as reference duration and whether the fresh air function is turned on under the corresponding reference duration. The first duration is compared with the reference duration to determine whether to turn on the fresh air function this time. Alternatively, any other possible method can be combined to determine whether to turn on the fresh air function based on the continuous first duration, and there is no limitation on this.

[0075] In some embodiments, if the first time length is greater than or equal to the first time length threshold, it is determined that the fresh air function is turned on; if the first time length is less than the first time length threshold, it is determined that the fresh air function is not turned on, thereby accurately determining whether to turn on the fresh air function.

[0076] In some embodiments, the first duration threshold may be, for example, a duration threshold for determining that the fresh air function is turned off for a long time.

[0077] In some embodiments, the first duration threshold may be, for example, between 30 minutes and 2 hours, or may be 30 minutes or 2 hours.

[0078] In some embodiments, the first duration threshold may be 60 minutes.

[0079] In some embodiments, if the first time duration is greater than or equal to the first time duration threshold, it indicates that the fresh air function is determined to be turned off for a long time. At this time, it can be determined to turn on the fresh air function to replace the indoor air.

[0080] In some embodiments, if the first time duration is less than the first time duration threshold, it indicates that the fresh air function has not been turned off for a long time. In this case, it can be determined not to turn on the fresh air function to avoid affecting the temperature control effect.

[0081] In some embodiments, the duration for which the fresh air function is not turned on can be determined, and the duration can be used as the first duration threshold to improve the reference value of the first duration threshold.

[0082] In some embodiments, the duration that the fresh air function is not turned on can also be understood as the duration after the fresh air function is exited. This duration can change dynamically. At each time point, the first duration that the real-time detected outdoor ambient temperature is in the second temperature range is compared with the duration after the fresh air function is exited to determine whether to turn on the fresh air function.

[0083] In this embodiment, the timing of turning on the fresh air function can be accurately determined, effectively avoiding affecting the indoor temperature control effect. If the number of interval changes is greater than the number threshold, it is determined that the fresh air function is turned on. If the number of interval changes is less than or equal to the number threshold, it is determined that the outdoor ambient temperature is in the second temperature interval for a first duration. According to the first duration, it is determined whether to turn on the fresh air function. This can greatly improve the accuracy of the judgment of the timing of turning on the fresh air function, effectively take into account the indoor temperature control effect and the fresh air effect, and improve the user experience.

[0084] Figure 3 It is a flow chart of a control method for a fresh air air conditioner proposed in another embodiment of the present disclosure.

[0085] like Figure 3 As shown, the control method of the fresh air air conditioner includes:

[0086] S301: Receive an on request instruction, wherein the on request instruction is used to request to turn on a fresh air function of the fresh air air conditioner.

[0087] S302: Determine the number of times the outdoor ambient temperature changes between a first temperature interval and a second temperature interval, wherein the first temperature interval and the second temperature interval are different.

[0088] S303: Determine to turn on the fresh air function according to the number of interval changes.

[0089] For the description of S301 - S303 , please refer to the above embodiment for details, which will not be repeated here.

[0090] S304: Turn on the fresh air function.

[0091] In some embodiments, when it is determined as above that the fresh air function is to be turned on, the fresh air function can be triggered to be turned on.

[0092] S305: Determine the second duration after the fresh air function is turned on.

[0093] In some embodiments, after the fresh air function is turned on, the fresh air function can be controlled to run for a specified period of time to effectively balance the fresh air effect and the indoor temperature control effect.

[0094] In some embodiments, after the fresh air function is turned on, a second duration after the fresh air function is turned on can be detected.

[0095] S306: If the second time duration reaches the second time duration threshold, the fresh air function is turned off.

[0096] In some embodiments, the second duration threshold may be, for example, a threshold value of the continuous operation duration of the fresh air function that can balance the fresh air effect and the indoor temperature control effect.

[0097] In some embodiments, the second duration threshold may be between 1 minute and 10 minutes, or may be 1 minute, or 10 minutes.

[0098] In some embodiments, the second duration threshold is, for example, 5 minutes.

[0099] In some embodiments, if the second time duration after the fresh air function is turned on reaches a second time duration threshold, the fresh air function can be turned off; if the second time duration after the fresh air function is turned on does not reach the second time duration threshold, the fresh air function can be maintained on until the second time duration after the fresh air function is turned on reaches the second time duration threshold.

[0100] In this embodiment, by receiving a start request instruction, wherein the start request instruction is used to request to turn on the fresh air function of the fresh air air conditioner, and determining the number of times the outdoor ambient temperature changes between a first temperature interval and a second temperature interval, wherein the first temperature interval and the second temperature interval are different, when it is determined to turn on the fresh air function based on the number of interval changes, the fresh air function is turned on, and the second time duration after the fresh air function is turned on is determined, and if the second time duration reaches a second time duration threshold, the fresh air function is turned off, thereby balancing the fresh air effect and the indoor temperature control effect to the greatest extent.

[0101] In an embodiment of the present disclosure, a method for timing the duration of each time the outdoor ambient temperature is in the second temperature range is also provided. When the fresh air function is turned on last time, if it is detected that the outdoor ambient temperature switches from the first temperature range to the second temperature range, the timing is started; if it is detected that the outdoor ambient temperature switches from the second temperature range back to the first temperature range, the timing is stopped to obtain the duration of each time the outdoor ambient temperature is in the second temperature range.

[0102] In some embodiments, the last time the fresh air function was turned on may be, for example, the last time the fresh air function was determined and turned on based on the method provided in the embodiments of the present disclosure, and there is no limitation on this.

[0103] In the embodiment of the present disclosure, the number of interval changes is determined based on the following method: when the fresh air function was turned on for the last time, the count was started, and when it was detected that the outdoor ambient temperature switched from the first temperature interval to the second temperature interval, the count was increased by one; when it was detected that the outdoor ambient temperature switched from the second temperature interval back to the first temperature interval, the count was increased by one until a turn-on request instruction was received, and the count was used as the number of interval changes, thereby effectively counting the number of interval changes.

[0104] In the embodiment of the present disclosure, when the fresh air function is determined and turned on this time, if it is detected that the outdoor ambient temperature switches from the first temperature range to the second temperature range, the timing is restarted to re-time the duration of the outdoor ambient temperature in the second temperature range each time.

[0105] In the embodiment of the present disclosure, when the fresh air function is determined and turned on, the count is restarted to support obtaining the number of times the new outdoor ambient temperature changes between the first temperature range and the second temperature range. When the next turn-on request instruction is received, it can be determined whether to respond to the next turn-on request instruction based on the new number of interval changes.

[0106] Optional embodiments:

[0107] It includes outdoor ambient temperature sampling, filtering and conversion, recording the number of interval changes in the outdoor ambient temperature and the duration in different temperature intervals. When the number of interval changes or the duration meets the threshold, the fresh air air conditioner is controlled.

[0108] In some embodiments, the outdoor ambient temperature can be detected based on the following method: the main board of the fresh air air conditioner outdoor unit transmits a sampling signal after sampling, the sampled signal is deeply filtered, and the average is calculated after sampling 32 times. The filtering depth in different situations can be determined according to the actual required control rate (the control rate can be, for example, the control response efficiency of the fresh air air conditioner). After the filtering is completed, analog-to-digital conversion is performed to obtain the accurate outdoor ambient temperature.

[0109] In some embodiments, the outdoor ambient temperature is recorded as interval 1 (an optional example of the first temperature interval) between [T fresh air turned on outer ring temperature lower limit] and [T fresh air turned on outer ring temperature upper limit], and the other temperature intervals are interval 2 (an optional example of the second temperature interval). When the interval changes, the number of changes N (an optional example of the number of interval changes) is recorded. After the remote control is turned on the fresh air function, the number of interval changes N is recorded. If the remote control turns on the fresh air and satisfies N> [fresh air change number threshold] (an optional example of the number threshold), or the remote control turns on the fresh air and the outdoor ambient temperature is maintained in interval 2 If the duration of the fresh air function is ≥ [Fresh air temperature exit time] (an optional example of the first duration threshold), it means that the fresh air effect is poor at this time, and it is often turned off or the switch is frequently switched. If this state is maintained for a long time, the indoor air will not be fresh. Therefore, the fresh air function can be turned on and the [Fresh air on time] (an optional example of the second duration threshold) is maintained. However, in order to improve the fresh air effect without destroying the indoor temperature, the time is moderately selected, and then normal judgment is restored (each time the fresh air function is turned on, the duration of the temperature range in which N and the outdoor ambient temperature are located is reset to zero and recalculated).

[0110] In some embodiments, [the lower limit of T fresh air opening outer ring temperature] is -10°C, [the upper limit of T fresh air opening outer ring temperature] is 53°C, [the fresh air change number threshold] is 10 times, [the fresh air temperature exit time] is 60 minutes, and [the fresh air forced opening operation time] is 5 minutes.

[0111] like Figure 4 As shown, Figure 4 It is a flow chart of a control method for a fresh air air conditioner proposed in another embodiment of the present disclosure, including: outdoor ambient temperature sampling, program processing, sampling signal filtering, analog-to-digital conversion to obtain the outdoor ambient temperature, if the outdoor ambient temperature changes between interval 1 and interval 2, counting to obtain the number of interval changes, judging whether the fresh air function is turned on by remote control, and whether the number of interval changes is greater than the [fresh air change number threshold], if so, turning on the fresh air function and maintaining the [fresh air start-up operation time], if not, judging whether the time the outdoor ambient temperature continues in interval 2 is greater than or equal to the [fresh air temperature exit time], if so, turning on the fresh air function and maintaining the [fresh air start-up operation time], if not, maintaining the current state.

[0112] The method provided by the embodiment of the present disclosure can effectively balance the indoor temperature control effect and the user's demand for fresh air under some extreme temperature conditions without increasing costs.
