Referring to fig. 1 and 2, in the present embodiment, the air conditioner 10 includes an air conditioner main body 100, a front panel 200, a first air guiding plate 310 and a second air guiding plate 320. The front panel 200 is disposed at the front side of the air conditioner main body 100, and an air outlet chamber 210 is formed between the front panel 200 and the air conditioner main body 100. Air conditioner main body 100 is last still to be equipped with air-out passageway 300, and air-out passageway 300 and air-out cavity 210 intercommunication, air-out cavity 210 are located the top of air-out passageway 300. The first air deflector 310 and the second air deflector 320 are both rotatably connected to the air conditioner main body 100, the first air deflector 310 is located above the second air deflector 320, and the front panel 200 is located above the first air deflector 310; the first air deflector 310 is used for opening or closing the first air outlet region 311 of the air outlet channel 300, the second air deflector 320 is used for opening or closing the second air outlet region 321 of the air outlet channel 300, and the first air outlet region 311 and the second air outlet region 321 jointly form an air outlet of the air outlet channel 300. The front panel 200, the first air guiding plate 310 and the second air guiding plate 320 are all provided with through holes for air flow to pass through.

In addition, the air conditioner 10 has a first zero wind condition and a second zero wind condition; when the air conditioner 10 is in the first zero wind state, the first air deflector 310 closes the first air outlet region 311 and the second air deflector 320 closes the second air outlet region 321; when the air conditioner 10 is in the second zero-wind state, the first air deflector 310 opens at least a portion of the first air outlet region 311, and the second air deflector 320 closes the second air outlet region 321.

When the air conditioner 10 is turned on in the first zero-wind state, a part of the airflow guided out from the air outlet channel 300 is guided out from the through holes of the first air deflector 310 and the second air deflector 320, and another part of the airflow is guided into the air outlet chamber 210 and then guided out from the through hole of the front panel 200.

In this embodiment, referring to fig. 3, the zero-wind control method includes:

and S11, controlling the air conditioner 10 to enter a first zero-wind state according to a zero-wind instruction set by a user.

The zero-wind command set by the user indicates a zero-wind command issued by the user through an operation panel or a gesture on the smart terminal, the remote controller, or the air conditioner 10. When the controller receives the zero wind command, the air conditioner 10 is controlled to enter the first zero wind state, that is, the first air deflector 310 and the second air deflector 320 are controlled to close the air outlet channel 300. Thus, the air flow from the air conditioner 10 is ensured to be dispersed, and the direct blowing of the air to the user is prevented.

And S13, starting timing when the air conditioner 10 enters the first zero-wind state.

And S15, after the timing duration reaches a first preset time, controlling the air conditioner 10 to switch between a first zero-wind state and a second zero-wind state according to the inner ring temperature value, the set temperature value and the inner ring humidity value.

The inner ring temperature value represents the temperature of the indoor environment in which the air conditioner 10 is located, and is detected by the inner ring temperature detection device and sent to the controller; the set temperature value represents a target temperature set by a user, namely the set temperature value represents a target temperature which the user expects the indoor temperature to reach; the inner loop humidity value represents the humidity of the indoor environment in which the air conditioner 10 is located, and is detected by the inner loop humidity detection device and sent to the controller. Based on the comparison between the indoor temperature and the set temperature, it can be determined whether the comfort level of the indoor environment substantially meets the user's requirement, and the air conditioner 10 can be controlled to switch to the first zero-wind state under the condition that the indoor environment substantially meets the user's requirement, so as to ensure that the airflow does not directly blow the user; the air conditioner 10 is controlled to be switched to the second zero wind state under the condition that the indoor environment cannot meet the user requirement, so that the refrigerating capacity of the air conditioner 10 is improved, and the comfort level of the indoor environment is improved to meet the user requirement.

Optionally, the value of the first preset time may be 1min to 5min, in other words, the value of the first preset time may be 1min, 1.5min, 2min, 2.5min, 3min, 3.5min, 4min, 4.5min, or 5min, and the like. Wherein, the first preset time is preferably 3min.

In the first zero-wind state of the air conditioner 10, the air output is affected, which may cause the air conditioning effect of the air conditioner 10 to the indoor space to be reduced; when the air conditioner 10 is in the second zero-wind state, a part of the first wind outlet region 311 is opened, so that the indoor air conditioning effect can be improved. Based on this, after the air conditioner 10 enters the first zero wind state for the first preset time, the operation state of the air conditioner 10 is stable, and at this time, the indoor humidity condition can be monitored by monitoring the indoor temperature and the set temperature value; to determine whether the comfort level is affected by the first zero-wind state of the air conditioner 10 according to the indoor temperature, the set temperature and the humidity. The air conditioner 10 is conveniently controlled to be switched between the first zero wind state and the second zero wind state, under the condition that a user is not directly blown, indoor comfort level can be guaranteed through switching between the first zero wind state and the second zero wind state, and use comfort level of the user is improved. Thereby achieving the purpose of improving the technical problem that the zero-wind mode of the air conditioner 10 in the prior art cannot ensure the comfortable environment of the user for a long time.

In addition, the indoor humidity condition is monitored, whether condensation is easy to occur in the air conditioner 10 can be judged according to the indoor humidity condition, the zero-wind mode can be switched according to the indoor humidity condition, and the condensation of the air conditioner can be reduced.

Optionally, referring to fig. 4, in an embodiment of the present application, step S15 may include:

s151, under the condition that the air conditioner 10 is in the first zero wind state, if the inner ring temperature value is greater than a first preset temperature value and the difference value of the inner ring temperature value minus the set temperature value is greater than a second preset temperature value; or, if the inner-ring humidity value is greater than the first preset humidity value, the air conditioner 10 is controlled to switch to the second zero-wind state.

Under the condition that the air conditioner 10 is in the first zero-wind state, if the inner ring temperature value is greater than the first preset temperature value, it indicates that the indoor temperature is higher, and meanwhile, the difference value between the inner ring temperature value and the set temperature value is greater than the second preset temperature value, which indicates that the difference between the indoor temperature and the set temperature is greater, so that the air output of the air conditioner 10 needs to be increased to conveniently adjust the indoor temperature to approach the set temperature value, and thus, the comfort level of a user is improved. In addition, when the inner loop humidity value is greater than the first preset humidity value, it indicates that the humidity in the room is too high, and it is necessary to dehumidify the indoor air by increasing the air output amount of the air conditioner 10. In this case, the air conditioner 10 needs to be switched to the second zero-wind state to improve the comfort level in the room.

Optionally, the first preset temperature value may be 24 ℃ to 27 ℃, in other words, the first preset temperature value may be 24 ℃, 25 ℃, 26 ℃ or 27 ℃, and the like. Wherein the first preset temperature value is preferably 26 ℃. In addition, the value of the second preset temperature value may be 1 ℃ to 3 ℃, in other words, the value of the second preset temperature value may be 1 ℃, 2 ℃ or 3 ℃, and the like, wherein the second preset temperature value is preferably 2 ℃. The first predetermined value of humidity may be 60% -75%, in other words, the first predetermined value of humidity may be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, etc. Wherein, the value of the first preset humidity value is preferably 70%.

S153, under the condition that the air conditioner 10 is in the second zero wind state, if the difference value of the inner ring temperature value minus the set temperature value is smaller than or equal to a third preset temperature value; or, if the inner-loop humidity value is smaller than the second preset humidity value, the air conditioner 10 is controlled to switch to the first zero-wind state.

When the air conditioner 10 is in the second zero-wind state, if the difference between the inner ring temperature value and the set temperature value is smaller than or equal to the third preset temperature value, it indicates that the difference between the indoor temperature and the temperature set by the user is small, that is, the indoor comfort level is high. In addition, when the inner ring humidity value is smaller than the second preset humidity value, the humidity of the indoor environment is low, and the indoor comfort level is high. Therefore, in the above case, it is possible to prevent the blow-through of the airflow by controlling the air conditioner 10 to switch to the first zero wind state. In addition, based on the comparison of inner ring humidity value and the second preset humidity value, the indoor humidity condition can be judged, and then whether condensation appears easily in the air conditioner 10 is conveniently judged, and indoor humidity is lower than the second preset humidity value, so that condensation is not easy to appear in the air conditioner 10, and based on the condensation, the air conditioner 10 can be adjusted to be in a first zero-wind state to improve the zero-wind effect and improve the comfort level of indoor users.

Optionally, the value of the third preset temperature value may be-1 ℃ to 1 ℃, in other words, the value of the third preset temperature value may be-1 ℃, 0 ℃ or 1 ℃ and the like, wherein the value of the third preset temperature value is preferably 0 ℃. The second predetermined humidity value may be 70% to 80%, in other words, the second predetermined humidity value may be 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, or the like. Wherein the second predetermined humidity value is preferably 75%. In addition, generally, the second preset humidity value is greater than or equal to the first preset humidity value.

Based on the above-mentioned zero-wind control method, the air conditioner 10 can switch between the first zero-wind state and the second zero-wind state based on the indoor comfort level, which not only can effectively achieve the purpose of preventing direct blowing, but also can ensure the indoor comfort level to meet the user's requirement for a long time.

Optionally, in the embodiment of the present application, in order to reduce energy consumption of the air conditioner 10 and improve operation stability of the air conditioner 10 when the air conditioner 10 performs a zero wind operation, the zero wind control method provided in the embodiment of the present application further includes frequency-limited control over the air conditioner 10.

Referring to fig. 5, in the case that the air conditioner 10 is in the first zero wind state, the zero wind control method further includes:

and S21, if the inner ring humidity value is smaller than or equal to the first humidity value, controlling the compressor to operate by taking the highest operation frequency of the compressor of the air conditioner 10 as the highest limit frequency.

Wherein the inner loop humidity value represents the humidity of the indoor environment in which the inner unit of the air conditioner 10 is located; the inner ring humidity value is detected by the inner ring humidity detection device and is sent to the controller. It is noted that, in the case where the inner ring humidity value is less than or equal to the first humidity value, it means that the humidity of the external environment is low, and thus it means that the humidity of the indoor environment is also low, and based on this, the operation of the compressor is controlled with the highest operation frequency as the highest limit frequency, so as to prevent the humidity in the room from being lowered, and to ensure the comfort in the room.

Whether the air conditioner 10 is easy to form condensation can be judged according to the indoor windshield and the inner ring humidity value, and the maximum limit frequency of the compressor is adjusted based on the judgment, so that the condensation of the air conditioner 10 is reduced. The indoor wind level indicates a gear of an indoor unit fan of the air conditioner 10.

Optionally, referring to fig. 6, in an embodiment of the present application, step S23 includes:

s231, determining a first frequency limiting proportion according to the indoor windshield and the inner ring humidity value, and taking the product of the highest running frequency and the first frequency limiting proportion as the highest limiting frequency.

And under any indoor wind shield, if the humidity value of the inner ring is larger, the frequency limiting ratio is smaller. That is, the higher the humidity of the indoor environment is when the indoor unit fan of the air conditioner 10 is at any gear, the easier it is to form condensation on the air conditioner 10, and based on this, the higher the frequency limit of the compressor is, that is, the smaller the ratio of the frequency limit is, the temperature of the heat exchanger of the indoor unit of the air conditioner 10 can be reduced, and the condensation on the air conditioner 10 can be reduced.

In the present embodiment, the indoor unit fan of the air conditioner 10 has a first wind speed and a sixth wind speed, which are sequentially reduced in rotation speed.

Wherein, step S231 includes:

under the condition that an inner fan of the air conditioner 10 is in a first wind gear, if the inner ring humidity value is smaller than or equal to a second humidity value, determining that the first frequency limiting proportion is a first proportion; if the inner ring humidity value is smaller than or equal to the third humidity value and larger than the second humidity value, determining that the first frequency limiting proportion is the second proportion; and if the inner ring humidity value is larger than the third humidity value, determining that the first frequency limiting proportion is the third proportion. Wherein the first proportion, the second proportion and the third proportion are all smaller than 1 and are reduced in sequence.

Alternatively, the first ratio may be 60% to 75%, in other words, the first ratio may be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, or the like. The second ratio may be 35% to 60%, in other words, the second ratio may be 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, or the like. The third ratio may be 30% to 35%, in other words, the third ratio may be 30%, 31%, 32%, 33%, 34%, 35%, or the like.

In addition, optionally, the second humidity value may be 58% to 62%, in other words, the second humidity value may be 58%, 59%, 60%, 61%, 62%, or the like, wherein the second humidity value is preferably 60%. The third humidity value may be 68% to 72%, in other words, the third humidity value may be 68%, 69%, 70%, 71%, or 72%, and the like, wherein the third humidity value is preferably 70%.

In addition, under the condition that the inner fan of the air conditioner 10 is in the sixth wind gear, if the inner ring humidity value is less than or equal to the second humidity value, the first frequency limiting ratio is determined to be the fourth ratio; if the inner ring humidity value is smaller than or equal to the third humidity value and larger than the second humidity value, determining the first frequency limiting proportion as a fifth proportion; and if the inner ring humidity value is larger than the third humidity value, determining that the first frequency limiting proportion is a sixth proportion, wherein the fourth proportion, the fifth proportion and the sixth proportion are all smaller than 1 and are sequentially reduced.

Optionally, in an embodiment of the present application, the fourth proportion is smaller than the first proportion, the fifth proportion is smaller than the second proportion, and the sixth proportion is smaller than the third proportion; because the internal fan is greater than the rotational speed of internal fan at the sixth wind-break at the rotational speed of first wind-break, this moment, the heat exchange efficiency that the internal fan provided the heat exchanger under the condition of first wind-break is higher, even under the slightly high condition of operating frequency of compressor, also can make the heat exchanger obtain better heat transfer, prevent that the temperature of heat exchanger is low excessively and easy condensation, also promptly, can reduce the condensation. The value of the fourth ratio may be 60% to 75%, in other words, the value of the fourth ratio may be 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, or the like. The fifth ratio may be 35% to 60%, in other words, the fifth ratio may be 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, or the like. The value of the sixth ratio may be 30% to 35%, in other words, the value of the sixth ratio may be 30%, 31%, 32%, 33%, 34%, or 35%.

It should be noted that the first wind gear and the sixth wind gear do not absolutely limit the rotation speed of the internal fan, and only the rotation speed of the internal fan at the first wind gear is higher than the rotation speed of the internal fan at the sixth wind gear. Further, in other embodiments of the present application, the above-mentioned "first gear" may also be split into a plurality of gears according to the rotation speed from high to low, for example, a high gear, a medium-low gear, a low gear, and a medium gear. Similarly, in some embodiments, the "sixth gear" may also be detached, and is not described herein again. Of course, in the case that the first gear is split, the frequency limiting control in any two gears may refer to the frequency limiting control in the case of the "first gear" and the "sixth gear" described above.

In addition, in the embodiment of the present application, when the air conditioner 10 is in the second zero wind state, the air output of the air conditioner 10 at this time is different from the air output of the air conditioner 10 in the first zero wind state, so that the frequency limitation control method of the air conditioner 10 in the second zero wind state for the compressor is different from the frequency limitation control method of the air conditioner 10 for the compressor in the first zero wind state, where please refer to fig. 7, the zero wind control method further includes:

and S31, receiving the running time.

Wherein the operation time represents a time when the air conditioner 10 operates the cooling mode; in other words, when the air conditioner 10 enters the cooling mode, the timer device starts to count time. The controller may obtain the running time directly from the timing device. The time length of the air conditioner running refrigeration mode can be recorded by timing the air conditioner running refrigeration mode, and whether the air conditioner provides enough refrigerating capacity indoors or not can be conveniently judged.

Alternatively, referring to fig. 8, step S33 includes:

and S331, if the running time does not reach the second preset time, taking the product of the seventh proportion and the highest running frequency as the highest limit frequency.

When the operation time does not reach the second preset time, the cooling capacity provided by the air conditioner 10 to the indoor space is not enough, and based on the fact that the maximum limiting frequency is adjusted to be the product of the seventh ratio and the maximum operation frequency, condensation can be reduced under the condition that the air conditioner 10 can provide enough cooling capacity.

Optionally, the value of the second preset time may be 13min to 17min, in other words, the value of the second preset time may be 13min, 14min, 15min, 16min, or 17min, and the like, where the value of the second preset time is preferably 15min.

Wherein the higher the inner loop humidity value, the lower the second frequency limiting ratio. In the case that the operation time reaches the second preset time, it indicates that the operation time of the air conditioner 10 is sufficient to provide a sufficient cooling capacity to the indoor, and based on this, the humidity of the indoor environment can be judged based on the humidity of the inner ring to frequency limit the compressor, and the condensation of the air conditioner 10 can be reduced. It should be noted that the value of the second frequency limiting ratio may refer to the value of the first frequency limiting ratio, which is not described herein again.

When the inner fan of the air conditioner 10 is in the second gear, the highest operating frequency is the highest limiting frequency, in other words, when the rotating speed of the inner fan is high, the heat exchanger has a good heat exchange efficiency, and at this time, the frequency limitation of the compressor is not needed. In addition, step S351 may include: under the condition that an inner fan of the air conditioner 10 is in a third wind gear or a fourth wind gear, if the outer ring temperature value is greater than or equal to a fifth preset temperature value, the highest operating frequency is taken as the highest limiting frequency, that is, the limitation on the compressor is not needed; and if the outer ring temperature value is less than the fifth preset temperature value, taking the product of the eighth proportion and the highest operation frequency as the highest limiting frequency.

In addition, the value of the ninth proportion may be 73% to 77%, in other words, the value of the ninth proportion may be 73%, 74%, 75%, 76%, 77%, or the like, wherein the value of the ninth proportion is preferably 75%.

S303, under the condition that the inner fan of the air conditioner 10 is in the fourth gear, if the outer ring temperature value is lower than the seventh preset temperature value, determining a fourth frequency limiting ratio according to the inner ring humidity value, and taking the product of the fourth frequency limiting ratio and the highest operating frequency as the highest limiting frequency.

Wherein the higher the inner loop humidity value is, the smaller the fourth frequency limiting ratio is. The determination of the fourth frequency limiting ratio may refer to the determination of the first frequency limiting ratio, and is not described herein again.

Alternatively, in the embodiment of the present application, in the case where the internal unit fan of the air conditioner 10 is in the second wind range, the highest operation frequency is the highest limit frequency.

And S355, if the operation time is longer than the third preset time, determining a third frequency limiting proportion according to the inner ring humidity value under the condition that the outer ring temperature value is smaller than a fourth preset temperature value, and taking the product of the third frequency limiting proportion and the highest operation frequency as the highest limiting frequency.

Wherein the higher the inner loop humidity value is, the smaller the third frequency limiting ratio is. Optionally, the determination of the third frequency limiting ratio may refer to the determination of the first frequency limiting ratio, which is not described herein again.

Optionally, the value of the third preset time may be 40min to 50min, in other words, the value of the third preset time may be 40min, 41min, 42min, 43min, 44min, 45min, 46min, 47min, 48min, 49min, 50min, or the like, wherein the value of the third preset time is preferably 45min.

In an embodiment of the application, the determination of the first frequency limiting proportion, the second frequency limiting proportion, the third frequency limiting proportion and the fourth frequency limiting proportion is determined based on an interval determined by three values, namely a first humidity value, a second humidity value and a third humidity value; it should be understood that, in other embodiments of the present application, any one humidity interval determined for the first humidity value, the second humidity value, and the third humidity value may also be divided according to actual situations, so as to divide the humidity interval into a plurality of humidity intervals. In the case where any one of the humidity sections is divided into a plurality of sections, the range section of the frequency-limited ratio corresponding to the humidity section may be divided into a plurality of corresponding ratio sections. For example, the interval defined by the first humidity value and the second humidity value is taken as an example; the interval may also be divided into an interval defined by the first and fourth humidity values and an interval defined by the fourth and second humidity values; the value of the fourth humidity value may be 53% to 57%, in other words, the value of the fourth humidity value may be 53%, 54%, 55%, 56%, 57%, or the like, and is preferably 55%. At this time, the section represented by the first ratio corresponding to the section defined by the first humidity value and the second humidity value may be divided into the section 60% to 65% and the section 65% to 75%, and the section defined by the first humidity value and the fourth humidity value may correspond to the section 60% to 65%, and the section defined by the fourth humidity value and the second humidity value may correspond to the section 65% to 75%. The divided intervals only need to satisfy the condition that the frequency limiting ratio is smaller when the humidity is larger.

It should be noted that, in the above-described embodiment, when the air conditioner 10 is in the first zero-wind state, the first wind level and the sixth wind level are divided into the indoor unit wind level of the air conditioner; in the case where the air conditioner 10 is in the second zero wind state, the second to fifth wind ranges are divided into the indoor unit wind range of the air conditioner 10. Wherein, in some embodiments, the sixth gear and the fifth gear may refer to the same gear; and the rotation speed range of the fan included in the first gear may be the same as the rotation speed range of the fan included in the second gear to the fourth gear. Of course, in other embodiments, the first wind level to the sixth wind level may be different from each other, in other words, in other embodiments, the air conditioner 10 may control the internal fans of the air conditioner 10 to operate in different gears independently from each other in the first zero wind state and in the second zero wind state.

In order to ensure that the air conditioner 10 can provide enough cooling capacity indoors, different frequency limiting steps can be performed according to the length of the operation time, so that condensation is reduced under the condition that the cooling capacity is ensured to be enough.

It is worth explaining that, under the condition that the operating frequency of the compressor is high, the temperature of the heat exchanger in the indoor unit of the air conditioner 10 is low, at this time, the gear of the indoor unit fan is promoted to help promote the heat exchange efficiency, so that the temperature of the heat exchanger is not too low, and further the temperature of the inner side of the front panel 200, the first air deflector 310 and the second air deflector 320, which is directly blown by the airflow, is prevented from being too low, and further condensation on the front panel 200, the first air deflector 310 and the second air deflector 320 can be reduced. Based on this, under the higher condition of fan gear, can improve the highest restriction frequency to guarantee the refrigerating output that air conditioner 10 can provide, and then guarantee user's comfort level. Correspondingly, under the condition that the gear of the fan of the internal machine is low, if the highest limit frequency of the compressor is high, the compressor runs at a high running frequency, so that the temperature of the heat exchanger of the internal machine is low, and the wind speed provided by the fan of the internal machine is not enough to provide high-efficiency heat exchange efficiency, so that the temperature of the heat exchanger is too low, and condensation is easily formed on the air conditioner 10; based on this, under the condition that the gear of the fan of the internal combustion engine is low, the maximum limit frequency of the compressor can be reduced, and the condensation of the air conditioner 10 can be reduced.

In addition, when the humidity of the inner ring is high, it indicates that the humidity in the room is high, and at this time, if the operating frequency of the compressor is increased, the temperature of the heat exchanger becomes too low, and the moisture in the air flow is easily condensed, and based on this, when the humidity in the room is high, the maximum limit frequency of the compressor is lowered to lower the operating frequency of the compressor, and the condensation in the air conditioner 10 can be reduced.

In the present embodiment, the maximum limit frequency of the air conditioner 10 in the first zero wind condition is lower than the maximum limit frequency of the air conditioner 10 in the second zero wind condition under the same environmental conditions. It can also be seen that, under the same environmental conditions, the frequency limiting ratio of the air conditioner 10 in the first zero wind state is smaller than the frequency limiting ratio of the air conditioner 10 in the second zero wind state.
