In one embodiment, when the parameter threshold is met, the next defrosting of the air conditioner comprises:
when the conditions that the temperature of the outdoor heat exchange tube is smaller than a first threshold value and the heating time is longer than a second threshold value are met, the air conditioner is defrosted for the next time.
The first threshold value is a tube temperature threshold value when the air conditioner enters a defrosting mode, and the second threshold value is a heating time length threshold value when the air conditioner enters the defrosting mode; for example, the first threshold is-8 ℃, the second threshold is 10min, when the tube temperature of the outdoor heat exchange tube is less than-8 ℃ and the heating time is longer than 10min, the air conditioner can enter the defrosting mode, so that the situation that the frost formation amount is small is avoided, the air conditioner frequently enters the defrosting mode, the operation energy consumption of the air conditioner is reduced, and the use experience of a user is influenced, and here, the first threshold is only used for explaining the parameter threshold entering the defrosting mode, and is not used for limiting the protection range of the present application.
Or
And when the heating time is longer than a second threshold value, defrosting the air conditioner for the next time.
For example, the second threshold is 10min, when the air conditioning heating duration is greater than 10min, the air conditioner may enter the defrosting mode, so as to avoid that the air conditioner frequently enters the defrosting mode under the condition of a small frosting amount, reduce the operation energy consumption of the air conditioner, and influence the use experience of a user.

if the numerical value of the indoor temperature difference before and after the defrosting is smaller than the first temperature difference value, judging that the defrosting amount is low;
if the numerical value of the indoor temperature difference before and after the defrosting is between the first temperature difference value and the second temperature difference value, judging that the frosting amount at this time is the normal frosting amount; wherein the first temperature difference value is less than the second temperature difference value, and the normal frosting amount is higher than the low frosting amount;
and if the numerical value of the indoor temperature difference before and after the current defrosting is larger than the second temperature difference value, judging that the current defrosting amount is a high defrosting amount, and the high defrosting amount is higher than the normal defrosting amount.
In a specific embodiment, determining a parameter threshold for entering a defrosting mode next time according to the current frosting amount and the current defrosting time length includes:
judging whether the frosting amount is normal or not;
if so, taking the parameter threshold value of the entering of the defrosting mode at this time as the parameter threshold value of the entering of the defrosting mode at the next time;
if not, acquiring a standard time length corresponding to the frost formation amount, and adjusting the parameter threshold value of the entering of the defrosting mode according to the relation between the defrosting time length and the standard time length to obtain the parameter threshold value of the entering of the defrosting mode next time.
The standard time corresponding to the frost formation amount is a fixed value, and after the standard time is set, the standard time is not generally adjusted.
In a specific embodiment, obtaining a standard time corresponding to the current frosting amount, and adjusting the parameter threshold value of the current entering of the defrosting mode according to a relationship between the current defrosting time and the standard time to obtain the parameter threshold value of the next entering of the defrosting mode includes:
when the current defrosting amount is the low defrosting amount, acquiring a low defrosting amount standard time length corresponding to the low defrosting amount, judging whether the current defrosting time length is smaller than the low defrosting amount standard time length, if so, reducing the first threshold of the current entering defrosting mode to obtain the first threshold of the next entering defrosting mode, and increasing the second threshold of the current entering defrosting mode to obtain the second threshold of the next entering defrosting mode;
or
When the current defrosting amount is the low defrosting amount, acquiring a low defrosting amount standard time corresponding to the low defrosting amount, judging whether the current defrosting time is shorter than the low defrosting amount standard time, if so, increasing the second threshold value of the current defrosting mode, and obtaining the second threshold value of the next defrosting mode.
When the current defrosting amount is low, but the defrosting time length is longer than the standard time of the low defrosting amount, the parameter threshold value is not adjusted, and the parameter threshold value of the current defrosting mode is used as the parameter threshold value of the next defrosting mode.
For example, when the current frosting amount is a low frosting amount, the standard time of the low frosting amount is 6min, the first threshold is-8 ℃, the second threshold is 10min, and the time of the current defrosting is 5min, in order to avoid the frequent entering of the air conditioner into the defrosting mode, the first threshold is adjusted to-9 ℃, and the second threshold is adjusted to 15min, the difficulty of the air conditioner entering the defrosting mode next time is improved by reducing the first threshold and increasing the second threshold, and the adjustment process of the parameter threshold is only used for explaining the adjustment process, and is not used for limiting the protection range of the present application.
Or
When the frost formation amount is low and the defrosting time is longer than the standard time of the low frost formation amount, the parameter threshold value is not adjusted, and the parameter threshold value entering the defrosting mode at this time is used as the parameter threshold value entering the defrosting mode at the next time.
For example, when the current frosting amount is a low frosting amount, the standard time of the low frosting amount is 6min, the second threshold is 10min, and the current defrosting time is 5min, in order to avoid the air conditioner from frequently entering the defrosting mode, the second threshold is adjusted to 15min, and the difficulty of the air conditioner entering the defrosting mode next time is increased by increasing the second threshold, which is only for explaining the process of adjusting the parameter threshold, and is not used for limiting the protection range of the present application.
In a specific embodiment, obtaining a standard time corresponding to the current frosting amount, and adjusting the parameter threshold value of the current entering of the defrosting mode according to a relationship between the current defrosting time and the standard time to obtain the parameter threshold value of the next entering of the defrosting mode includes:
when the current defrosting amount is the high defrosting amount, acquiring a high defrosting amount standard time corresponding to the high defrosting amount, judging whether the defrosting time is longer than the high defrosting amount defrosting time, if so, increasing the first threshold of the current defrosting mode to obtain the next defrosting mode, and reducing the second threshold of the current defrosting mode to obtain the next defrosting mode; if not, improving the heat output of the air conditioner;
or
When the current defrosting amount is the high defrosting amount, acquiring a high defrosting amount standard time length corresponding to the high defrosting amount, judging whether the defrosting time length is greater than the high defrosting amount defrosting time length, if so, reducing the second threshold value of the current defrosting mode, and acquiring a parameter threshold value of the next defrosting mode; and if not, improving the heat output of the air conditioner.
When the frosting amount is high, but the defrosting time is longer than the high frosting amount standard time, the parameter threshold is not adjusted, the parameter threshold entering the defrosting mode at this time is used as the parameter threshold entering the defrosting mode next time, and because the indoor temperature difference of the user is large, the user is easy to generate obvious cold feeling, probably because the heat dissipation of the room of the user is too large, the heat output of the air conditioner is improved, the room temperature of the user is maintained in a comfortable range, and the use experience of the user is improved.
For example, when the frost formation amount is a high frost formation amount, the standard time of the high frost formation amount is 5min, the first threshold is-8 ℃, the second threshold is 10min, and the defrosting time is 6min, in order to avoid that the air conditioner frequently enters the defrosting mode, the first threshold is adjusted to-7 ℃, and the second threshold is adjusted to 8min, by increasing the first threshold and reducing the second threshold, the difficulty of the air conditioner entering the defrosting mode next time is reduced, and the situation that the difference of the room temperature of the user after defrosting is too large due to over-thick frost formation is prevented, which is only for explaining the process of adjusting the parameter threshold, and is not used for limiting the protection range of the present application.
Or
When the frosting amount is high, but the defrosting time is less than the high frosting amount standard time, the parameter threshold is not adjusted, the parameter threshold entering the defrosting mode at this time is taken as the parameter threshold entering the defrosting mode next time, and because the indoor temperature difference of the user is large, the user is easy to generate obvious cold feeling, probably because the heat dissipation of the room of the user is too large, the heat output of the air conditioner is improved, the room temperature of the user is maintained in a comfortable range, and the use experience of the user is improved.
For example, when the frost formation amount is a high frost formation amount, the standard time of the high frost formation amount is 5min, the second threshold is 10min, and the defrosting time is 6min, in order to avoid that the air conditioner frequently enters the defrosting mode, the second threshold is adjusted to 8min, by reducing the second threshold, the difficulty of the air conditioner entering the defrosting mode next time is reduced, and the condition that the room temperature difference of a user is too large after defrosting due to too thick frost formation is prevented, which is only for explaining the process of adjusting the parameter threshold, and is not used for limiting the protection range of the present application.
And step 203, when the parameter threshold is met, defrosting the air conditioner for the next time.
One specific example will be provided below:
as shown in fig. 3, step 301, after entering the defrost mode, detects and acquires the indoor temperature of the user at this time, and starts timing.
And 302, defrosting according to preset operation parameters.
