[0028] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the preceding and following objects. For example, A / B represents: A or B.

[0029] The term "and / or" is a description of the association relationship between objects, which means that there can be three relationships. For example, A and / or B means: A or B, or, A and B, the three relationships.

[0030] The term "corresponding" can refer to an association relationship or a binding relationship. A and B correspond to each other means that there is an association relationship or a binding relationship between A and B.

[0031] The embodiment of the present disclosure provides an air conditioner, which comprises an air conditioner body and a sound wave device. The sound wave device is arranged at an air outlet position of the air conditioner body. The sound wave direction of the sound wave device is perpendicular to the air outlet direction of the air conditioner. Optionally, the sound wave device is arranged in an air duct and located at the front side of a guide vane and a swing vane. After the sound wave device is turned on, the air outlet of the cross-flow fan can be directly disturbed, and the disturbance effect is not affected by the air outlet angle. Optionally, the sound wave device is arranged on the guide vane and moves with the opening and closing of the guide vane, and is always perpendicular to the air outlet direction, so as to realize the disturbance of the air and the disturbance effect is not affected by the angle of the guide vane.

[0032] Optionally, the sound wave device is a plurality of sound wave devices. The air conditioner body has an air outlet. The side of the cross-flow fan of the indoor unit facing the air outlet corresponds to the plurality of sound wave devices. Meanwhile, the plurality of sound wave devices correspond to different positions of the cross-flow fan. Specifically, the plurality of sound wave devices are arranged on the guide vane along the length direction of the guide vane, or arranged in the air duct along the length direction of the air duct.

[0033] The air conditioner further comprises a controller. The controller is in communication connection with the sound wave device to control the operation parameter of the sound wave device.

[0034] In combination with Fig. 1 The embodiment of the present disclosure provides a method for controlling the windless air outlet of an air conditioner, which comprises the following steps.

[0035] S101, the air conditioner obtains the rotating speed of the fan when the air conditioner needs to have windless air outlet.

[0036] S102, the air conditioner determines the target operation parameter of the sound wave device according to the rotating speed of the fan.

[0037] S103, the air conditioner controls the sound wave device to operate according to the target operation parameter.

[0038] The air conditioner has a windless air outlet mode. When the air conditioner receives the instruction of starting the windless air outlet mode sent by the user through a remote controller or the like, it is determined that the air conditioner needs to have windless air outlet. Or the outer wall of the air conditioner body is provided with a radar or a camera in communication connection with the controller to monitor whether there is a user in the space where the air conditioner is located. When no user is monitored, the air conditioner normally operates. When a user is monitored, it is determined that the air conditioner needs to have windless air outlet. When no user is monitored for a preset time period, the sound wave device is controlled to be turned off.

[0039] When it is determined that the air conditioner needs to blow air without wind feeling, the rotating speed of the cross-flow fan (hereinafter referred to as "fan") of the indoor unit is obtained. According to the rotating speed of the fan, the target operating parameter of the sound wave device is determined. The sound wave device causes vibration of air by means of the sound wave emitted by itself, and then generates air pressure. When the pressure accumulates to a certain extent, it can disturb the original air outlet of the air conditioner. And because the direction of the sound wave is perpendicular to the direction of the air outlet, the sound wave interferes with the air flow of the fan, thereby realizing the air outlet without wind feeling. The operating parameters of the sound wave device mainly include: sound intensity and sound wave frequency. The sound wave device is controlled to operate according to the determined target operating parameter, so that the effect of the sound wave device on the air flow is matched with the current rotating speed of the fan. The greater the rotating speed of the fan, the greater the wind speed, and the greater the degree of disturbance of the sound wave device to the air flow, so as to realize the air outlet without wind feeling.

[0040] The method for controlling the air conditioner to blow air without wind feeling provided by the embodiment of the present disclosure is adopted. Based on the rotating speed of the fan, the target operating parameter of the sound wave device is determined, and then the sound wave device is controlled to operate according to the target operating parameter. The sound wave emitted by the sound wave device interferes with the air flow of the air conditioner, and at the same time, the target operating parameter of the sound wave device is matched with the rotating speed of the fan, thereby realizing the air outlet without wind feeling. In this way, the sound wave device only disturbs the air flow and does not affect the air volume. At the same time, only the sound wave device needs to be added to the air conditioner to realize the air outlet without wind feeling, without the need to make substantial changes to the original structure of the air conditioner, which is convenient to implement.

[0041] In combination with Fig. 2 The embodiment of the present disclosure provides another method for controlling the air conditioner to blow air without wind feeling, which comprises:

[0042] S101, the air conditioner obtains the rotating speed of the fan in the case of needing to blow air without wind feeling.

[0043] S112, the air conditioner determines the target sound intensity of the sound wave device according to the rotating speed of the fan; and / or determines the target sound wave frequency of the sound wave device according to the rotating speed of the fan.

[0044] S103, the air conditioner controls the sound wave device to operate according to the target operating parameter.

[0045] The parameters of the sound wave device include: sound intensity S and sound wave frequency F. The target sound intensity of the sound wave device is determined according to the rotating speed of the fan, and / or the target sound wave frequency of the sound wave device is determined according to the rotating speed of the fan. In this way, the sound intensity of the sound wave device can be adjusted alone, the sound wave frequency can be adjusted alone, or the sound intensity and the sound wave frequency can be adjusted simultaneously. The controller of the air conditioner pre-stores the correlation between the rotating speed of the fan and the sound intensity, which includes one or more corresponding relationships between the rotating speed of the fan and the sound intensity. Among them, the rotating speed of the fan is positively correlated with the sound intensity. The greater the rotating speed interval of the fan, the greater the sound intensity. Specifically, refer to Table 1.

[0046] Table 1: Relationship between fan speed and sound intensity

[0047]

[0048]

[0049] In Table 1, V1 < V2 < V3 < V4 < V5, S1 < S2 < S3 < S4 < S5. For example, if the current fan speed V is in the interval (V2, V3], or the current air outlet mode is the medium air outlet mode, it is determined that the target sound intensity of the sound wave device is S3.

[0050] The controller of the air conditioner also pre-stores a relationship between the fan speed and the sound wave frequency, which includes one or more corresponding relationships between the fan speed and the sound wave frequency. The fan speed and the sound wave frequency are positively correlated. The larger the speed interval of the fan speed, the greater the sound wave frequency. For details, see Table 2.

[0051] Table 2: Relationship between fan speed and sound wave frequency

[0052] Fan rotation speed V (rpm) Sound wave frequency F (Hz) (0, V1] (Silent) F1 (V1, V2] (Low wind) F2 (V2, V3] (Medium wind) F3 (V3, V4] (High wind) F4 (V4, V5] (Strong wind) F5

[0053] In Table 2, V1 < V2 < V3 < V4 < V5, F1 < F2 < F3 < F4 < F5. For example, if the current fan speed V is in the interval (V3, V4], or the current air outlet mode is the high air outlet mode, it is determined that the target sound wave frequency of the sound wave device is F4.

[0054] In this way, based on the fan speed, i.e., the size of the air outlet airflow of the air conditioner, the target sound intensity and / or the target sound wave frequency of the sound wave device are determined. The sound intensity and / or the sound wave frequency when the sound wave device operates are matched with the size of the air outlet airflow, i.e., the degree of turbulence is matched with the air outlet airflow, so as to achieve windless air outlet.

[0055] In combination Fig. 3 As shown in the drawings, the embodiment of the present disclosure provides another method for controlling windless air outlet of an air conditioner, which comprises:

[0056] S101, the air conditioner acquires the fan speed in a case where windless air outlet of the air conditioner is needed.

[0057] S112, the air conditioner determines the target sound intensity of the sound wave device according to the fan speed; and / or determines the target sound wave frequency of the sound wave device according to the fan speed.

[0058] S122, the air conditioner determines the target duty cycle of the sound wave device according to the operating temperature of the air conditioner.

[0059] S103, the air conditioner controls the sound wave device to operate according to the target operating parameter.

[0060] After the target sound intensity and / or the target sound wave frequency of the sound wave are determined, the operating temperature of the air conditioner is further acquired, and the target duty cycle of the sound wave device is determined according to the operating temperature of the air conditioner. The duty cycle of the sound wave device is different, and the continuity of the windless air outlet is different. When the duty cycle is 100%, the working mode of the sound wave device is continuous mode, and the air outlet of the air conditioner is continuous windless. When the duty cycle is less than 100%, the working mode of the sound wave device is pulse mode, and the windless air outlet of the air conditioner is intermittent. The smaller the duty cycle is, the shorter the operation time of the sound wave device is, and the shorter the time of each windless air outlet of the air conditioner is. With the operation of the air conditioner, the operating temperature of the air conditioner gradually approaches the set temperature of the user. According to the difference between the operating temperature of the air conditioner and the set temperature, the duty cycle of the sound wave device is adjusted to reduce the energy consumption of the sound wave device.

[0061] Optionally, in S122, the air conditioner determines the target duty cycle of the sound wave device according to the operating temperature of the air conditioner, including:

[0062] In S1122, the air conditioner determines that the target duty cycle of the sound wave device is a first duty cycle when the operating temperature of the air conditioner reaches the set temperature.

[0063] In S1222, the air conditioner determines that the target duty cycle of the sound wave device is a second duty cycle when the operating temperature of the air conditioner does not reach the set temperature.

[0064] The second duty cycle is greater than the first duty cycle.

[0065] When the operating temperature of the air conditioner reaches the set temperature, the air conditioner enters a low-power operating state to maintain the current temperature. At this time, the air flow is small, so the target duty cycle of the sound wave device is determined to be a smaller first duty cycle. When the operating temperature of the air conditioner does not reach the set temperature, the air conditioner remains in a high-power operating state to ensure the heat exchange efficiency. At this time, the air flow is large, so the target duty cycle of the sound wave device is determined to be a larger second duty cycle. Optionally, the first duty cycle is less than 100%, and at this time the sound wave device operates in pulse mode. The second duty cycle is 100%, and at this time the sound wave device operates in continuous mode.

[0066] Optionally, the operating temperature reaching the set temperature can be that the temperature difference between the operating temperature and the set temperature is within a preset temperature difference range. Conversely, the operating temperature not reaching the set temperature can be that the temperature difference between the operating temperature and the set temperature is outside the preset temperature difference range.

[0067] Optionally, the controller of the air conditioner also pre-stores an association relationship between a temperature difference between the operating temperature and the set temperature and the duty cycle, the association relationship including one or more corresponding relationships between the temperature difference and the duty cycle. The association relationship is called when the operating temperature of the air conditioner does not reach the set temperature. The temperature difference and the duty cycle are positively correlated. The greater the temperature difference interval in which the temperature difference ΔT is located, the greater the target duty cycle A of the sound wave device. For details, see Table 3.

[0068] Table 3: Association relationship between temperature difference between operating temperature and set temperature and duty cycle

[0069] Temperature difference ΔT (°C) Target duty ratio A (%) (ΔT1, ΔT2] A1 (ΔT2, ΔT3] A2 (ΔT3, ΔT4] A3 (ΔT4, ΔT5] A4

[0070] In Table 3, ΔT1<ΔT2<ΔT3<ΔT4<ΔT5, A1<A2<A3<A4, and A4<100%. For example, when the operating temperature does not reach the set temperature and the temperature difference between the two is in the interval (ΔT3, ΔT4], the target duty cycle of the sound wave device is determined to be A3.

[0071] In this way, the target duty cycle of the sound wave device is adjusted in real time based on the size of the operating temperature and the set temperature of the air conditioner, so that the operating time of the sound wave device matches the actual demand, thereby achieving the purpose of reducing energy consumption.

[0072] In combination Fig. 4 As shown in the drawings, the embodiments of the present disclosure provide another method for controlling the windless air outlet of an air conditioner, comprising:

[0073] S101, the air conditioner obtains the rotating speed of the fan when it needs to have a windless air outlet.

[0074] S112, the air conditioner determines the target sound intensity of the sound wave device according to the rotating speed of the fan; and / or determines the target sound wave frequency of the sound wave device according to the rotating speed of the fan.

[0075] S1122, the air conditioner determines the target duty cycle of the sound wave device to be a first duty cycle when the operating temperature of the air conditioner reaches the set temperature.

[0076] S1222, the air conditioner determines the target duty cycle of the sound wave device to be a second duty cycle when the operating temperature of the air conditioner does not reach the set temperature. The second duty cycle is greater than the first duty cycle.

[0077] S104, the air conditioner obtains the position of the user after executing S1122.

[0078] S105, the air conditioner corrects the target duty cycle of the sound wave device according to the position of the user.

[0079] S106, the air conditioner takes the corrected target duty cycle as a new target duty cycle.

[0080] S103, the air conditioner control sound wave device operates according to the target operating parameter.

[0081] The outer wall of the air conditioner body is provided with a radar or a camera in communication connection with the controller to obtain the position of the user. According to the position of the user, the distance between the user and the air conditioner body is determined, and then the target duty cycle is corrected. The corrected target duty cycle is taken as a new target duty cycle. Then the control sound wave device operates according to the new target duty cycle. Alternatively, the controller also pre-stores an association relationship between the distance between the user and the air conditioner body and the correction value, which includes one or more corresponding relationships between the distance and the correction value. Wherein, the distance and the correction value are negatively correlated. The greater the distance interval ΔS is, the smaller the determined correction value ΔA is. For details, see Table 4.

[0082] Table 4 Association relationship between the distance between the user and the air conditioner body and the correction value

[0083] Pitch ΔS (m) Correction value ΔA (%) (0, ΔS1] ΔA1 (ΔS1, ΔS2] ΔA2 (ΔS2, ΔS3] ΔA3 (ΔS3, ΔS4] ΔA4 (ΔS4, +∞) ΔA5

[0084] In Table 4, ΔS1<ΔS2<ΔS3<ΔS4, ΔA1>ΔA2>ΔA3>ΔA4>ΔA5.

[0085] When ΔS∈(0, ΔS2], the target duty cycle is positively corrected. When ΔS∈(ΔS2, ΔS3], the target duty cycle is not corrected, i.e. ΔA3=0. When ΔS∈(ΔS3, +∞), the target duty cycle is negatively corrected. For example, the current target duty cycle is A3. ΔS is located in the interval (ΔS3, ΔS4], and the correction value of the duty cycle is determined as ΔA4, then the new target duty cycle is A3+ΔA4.

[0086] In this way, after the target duty cycle of the sound wave device is determined, the target duty cycle is further corrected based on the distance between the user and the air conditioner body. The farther the distance between the user and the air conditioner body is, the less obvious the feeling of the air flow is, so the target duty cycle can be negatively corrected to control the degree of windless air outlet of the air conditioner to be reduced. In this way, the purpose of further reducing the energy consumption of the sound wave device can be achieved.

[0087] The above control logic is applicable to the case where only one sound wave device is provided.

[0088] In combination Fig. 5 As shown in the figure, the embodiment of the present disclosure provides another method for controlling the windless air outlet of the air conditioner, comprising:

[0089] S101, the air conditioner obtains the rotating speed of the fan in the case where the windless air outlet of the air conditioner is needed.

[0090] S102, the air conditioner determines the target operating parameter of the sound wave device according to the rotating speed of the fan.

[0091] S103, the air conditioner controls the sound wave device to operate according to the target operating parameter.

[0092] S107, the air conditioner obtains the wind speed at the position of each sound wave device.

[0093] S108, the air conditioner determines the target sound wave device according to the rotation speed of the fan and the wind speed at each position.

[0094] S109, the air conditioner adjusts the operating parameter of the target sound wave device according to the wind speed at the position of the target sound wave device.

[0095] After the sound wave device is controlled to operate according to the target operating parameter, the sound wave device will interfere with the air outlet airflow of the air conditioner, so as to make the air conditioner realize the air-outlet-feeling-free. After the air conditioner is used for a long time, dust will accumulate at a certain position of the fan, or there are foreign matters at a certain position of the air outlet of the air conditioner, etc., which will cause the problem that the air outlet at each position is different. Therefore, a plurality of sound wave devices are arranged at the air outlet position, and the plurality of sound wave devices correspond to different positions of the side of the fan facing the air outlet position. Each sound wave device is also respectively arranged with a wind speed sensor near it. The controller is in communication connection with the plurality of wind speed sensors to obtain the wind speed at the position of the corresponding sound wave device. The target sound wave device is determined according to the rotation speed of the fan and the wind speed at each position. The operating parameter of the target sound wave device is further adjusted according to the wind speed at the position of the target sound wave device. So that the interference degree of the target sound wave device to the air outlet airflow at the position matches the actual wind speed at the position. In this way, the energy consumption of the sound wave device can be further reduced. The operating parameter of the non-target sound wave device can still be controlled according to the logic described above.

[0096] Optionally, in step S108, the air conditioner determines the target sound wave device according to the rotation speed of the fan and the wind speed at each position, comprising:

[0097] The air conditioner determines the standard wind speed according to the rotation speed of the fan.

[0098] The air conditioner determines the sound wave device corresponding to the position with the wind speed difference between the wind speed and the standard wind speed not in the preset wind speed difference range as the target sound wave device.

[0099] The controller of the air conditioner pre-stores standard wind speed corresponding to the rotation speed of the fan. The corresponding standard wind speed is determined according to the current rotation speed of the fan. The wind speed detected by each wind speed sensor is compared with the standard wind speed. If the wind speed difference between the wind speed detected by the wind speed sensor and the standard wind speed is not within the preset wind speed difference range, it indicates that the wind speed at this position is small, and the sound wave device corresponding to the wind speed sensor is determined as the target sound wave device. The upper limit value of the preset wind speed difference range is ΔV1, and when the wind speed at the current position is greater than ΔV1, the sound wave device corresponding to the current position is determined as the target sound wave device. In this way, the sound wave device at the position with small wind speed is determined as the target sound wave device, so as to adjust the operating parameters thereof. The operating parameters are matched with the wind speed at the position, so as to achieve the purpose of reducing the energy consumption of the target sound wave device.

[0100] Optionally, in step S109, the air conditioner adjusts the operating parameters of the target sound wave device according to the wind speed at the position where the target sound wave device is located, including:

[0101] The air conditioner calculates the wind speed difference between the standard wind speed and the wind speed at the position where the target sound wave device is located.

[0102] The air conditioner determines the sound intensity correction value of the target sound intensity and / or the frequency correction value of the target sound wave frequency according to the wind speed difference.

[0103] The air conditioner corrects the target sound intensity according to the sound intensity correction value and / or corrects the target sound wave frequency according to the frequency correction value.

[0104] Calculate target ΔV = Vb-V, where V is the wind speed at the position where the target sound wave is located, and Vb is the standard wind speed. The larger the wind speed difference interval ΔV is, the smaller the sound intensity correction value ΔS and the frequency correction value ΔF are. Here, ΔS and ΔF are both negative values. That is, the more the target sound intensity and / or the target sound wave frequency are controlled to decrease. The controller also pre-stores the correlation between the wind speed difference value and the sound intensity correction value and the frequency correction value. Specifically, refer to Table 5.

[0105] Table 5 Correlation between wind speed difference value and sound intensity correction value and frequency correction value

[0106]

[0107] In Table 5, ΔV1<ΔV2<ΔV3<ΔV4, 0>ΔS1>ΔS2>ΔS3>ΔS4, 0>ΔF1>ΔF2>ΔF3>ΔF4. For example, the current target sound intensity is A4, and the target sound wave frequency is F4. ΔV is located in the interval (ΔV3, ΔV4], the sound intensity correction value is determined as ΔS3, and the frequency correction value is determined as ΔF3. Then the new target sound intensity is A4+ΔS3, and the new target sound wave frequency is F4+ΔF3.

[0108] In this way, the target sound intensity and / or the target sound wave frequency are corrected according to the difference between the actual air outlet speed at different positions and the standard air speed, so that the operation parameters of the sound wave device are matched with the air speed at the corresponding position. Thus, the overall energy consumption of the sound wave device is further reduced.

[0109] In combination Fig. 6 As shown in the drawings, the embodiment of the present disclosure provides a device 60 for controlling air conditioner windless air outlet, comprising: an acquisition module 61, a determination module 62 and a control module 63. The acquisition module 61 is configured to acquire the rotating speed of the fan in the case of needing air conditioner windless air outlet. The determination module 62 is configured to determine the target operation parameters of the sound wave device according to the rotating speed of the fan. The control module 63 is configured to control the sound wave device to operate according to the target operation parameters.
