[0002] With the improvement of air conditioner energy efficiency and people's demand for air conditioner comfort, variable frequency air conditioners have been accepted and liked by more and more users. Compared with fixed frequency air conditioners, variable frequency air conditioners have a wider operating frequency range, but due to factors such as the noise vibration of the compressor body and the fixed frequency of the pipeline, some operating frequency points have problems such as noise difference and high stress, which need to be shielded. For some air conditioners, there will be continuous shielding operating frequency points of the compressor, which will trigger the frequency limit protection during the frequency increase process. For example, if there is a continuous shielding operating frequency point, the frequency will be reduced to a non-shielded frequency point; after exiting the frequency limit protection, the frequency can be increased again.

[0038] Figure 2 It is a schematic structural diagram of a frequency control device according to an exemplary embodiment.

[0039] Figure 3 The diagram is a schematic structural diagram of a household appliance according to an exemplary embodiment.

[0040] Figure 4 The figure is a schematic diagram showing the structure of a chip according to an exemplary embodiment. DETAILED DESCRIPTION

[0041] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] It should be noted that all actions of acquiring signals, information or data in the present disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the device is located and with the authorization given by the owner of the corresponding device.

[0043] See also Figure 1 FIG. 1 is a flow chart showing a frequency control method according to an exemplary embodiment. Figure 1 The method shown can be applied to household appliances, including but not limited to air conditioners, washing machines, dryers or other household appliances with compressors. The present disclosure takes the household appliance as an air conditioner as an example to explain the relevant content, but it does not constitute a limitation. Figure 1 The method shown may include the following implementation steps:

[0044] S101. Obtain frequency limiting parameters, where the frequency limiting parameters at least include the number of frequency limiting times and the frequency limiting frequency. The number of frequency limiting times is the number of times the compressor is continuously triggered to perform frequency limiting protection within a preset first time in the frequency increasing stage, and the frequency limiting frequency is the operating frequency of the compressor each time the frequency limiting protection is performed.

[0045] The above-mentioned frequency limiting parameters disclosed in the present invention may refer to the working parameters that trigger the compressor to perform frequency limiting protection within the preset first time during the frequency increase stage or process, which may include but are not limited to, for example, the number of frequency limiting times and the frequency limiting frequency, and may optionally include the frequency limiting interval or other custom parameters. Among them, the above-mentioned frequency limiting times may refer to the number of times the compressor is continuously triggered to perform frequency limiting protection within the preset first time during the frequency increase process, which may also be referred to as the continuous number of times. The above-mentioned frequency limiting interval refers to the time interval between two adjacent times that the above-mentioned compressor is triggered to perform frequency limiting protection, and the above-mentioned frequency limiting frequency may refer to the operating frequency of the above-mentioned compressor each time the frequency limiting protection is performed.

[0046] It is understandable that the compressor may trigger frequency limiting protection (also referred to as frequency reduction protection) during the frequency increase process due to reasons such as excessively high exhaust temperature (greater than the preset exhaust temperature), excessively high external tube temperature (greater than the preset external tube temperature), or excessively high working current (greater than the preset working current). At the same time, because its operating frequency may be within the continuous shielding frequency points (that is, the operating frequency of the compressor is within the preset shielding frequency range), the compressor may not be able to operate stably and needs to be reduced to the non-shielding frequency (point). At this time, the number of frequency limiting (also referred to as the number of frequency reduction) for the compressor may be recorded as 1. In the embodiment of the present disclosure, if the compressor has frequency limiting protection again within the preset first time and its operating frequency is reduced within the above-mentioned preset shielding frequency range, the above-mentioned number of frequency limiting may be recorded as 1. On the contrary, if the frequency limiting protection does not occur again within the preset first time, the above-mentioned number of frequency limiting may be cleared and processed. The above-mentioned preset first time may be the frequency anti-fluctuation judgment time set by the household appliance or the user, for example, it may be 5 minutes or 20 minutes. Usually, the above-mentioned preset first time may be any value between 5 minutes and 20 minutes.

[0047] The present disclosure does not limit the implementation method for obtaining the above-mentioned frequency limiting parameters. For example, during the frequency increase process, the parameters generated by triggering the compressor to perform frequency limiting protection can be automatically counted; or they can be obtained from other devices (such as servers or terminal devices, etc.) through the network, etc. The present disclosure does not limit this.

[0048] S102: When the frequency limit parameter is within a corresponding preset range, anti-fluctuation control is performed on the operating frequency of the compressor, wherein the anti-fluctuation control includes frequency rise time control and / or maintenance time control of the frequency limit protection.

[0049] The present disclosure can determine whether the above-mentioned frequency limiting parameter is within the corresponding preset range (that is, whether the above-mentioned frequency limiting parameter meets the corresponding preset condition). If so, the frequency fluctuation prevention control of the compressor can continue; otherwise, the process can be terminated. Among them, the above-mentioned preset range or the above-mentioned preset condition can be a household appliance or a user-defined setting, which is used to determine whether the compressor is protected or controlled against frequency fluctuations. Usually, the preset range (or preset condition) may include but is not limited to, for example, the above-mentioned frequency limiting number is greater than or equal to the preset number, and the above-mentioned frequency limiting frequency is within the preset shielding frequency range (that is, the operating frequency of the compressor needs to be reduced within the shielding frequency range). When the above-mentioned frequency limiting parameter also includes a frequency limiting interval, the above-mentioned preset range or preset condition may also include: the above-mentioned frequency limiting interval is less than or equal to the above-mentioned preset first time (that is, the above-mentioned frequency limiting interval needs to be within the above-mentioned preset first time). The above-mentioned preset number is a number threshold value set by the system, for example, it can be an experience value set according to user experience, or it can be a statistical value set according to a series of experimental data. Taking the above preset number of times as 3 as an example, the above preset range (or preset condition) can specifically be that the frequency limit protection occurs 3 times in succession, and the frequency is reduced within the preset shielding frequency range, and the interval between the two frequency reductions (also called the frequency limit interval) is within the above preset first time. When the above frequency limit parameter is within the corresponding preset range, the anti-fluctuation protection can be entered, that is, the operating frequency of the compressor is controlled to prevent fluctuations. On the contrary, when the above frequency limit parameter is not within the corresponding preset range, there is no need to perform anti-fluctuation protection / control, and the process can be terminated.

[0050] The present disclosure does not limit the specific implementation methods of the above-mentioned anti-fluctuation control. For example, it may include but is not limited to, for example, frequency increase time control and / or frequency limit protection maintenance time control. In specific implementation, when the above-mentioned anti-fluctuation control includes frequency increase time control, the present disclosure may shield the above-mentioned triggering frequency limit protection for the compressor, and then continue to perform frequency increase processing on the operating frequency of the above-mentioned compressor, wherein the operating frequency after the frequency increase processing is outside the above-mentioned shielding frequency range, which may also be referred to as a non-shielded frequency (point), etc. Further optionally, if the household appliance does not detect any frequency reduction protection for the compressor, the operating frequency after the frequency increase processing may continue to be maintained within a preset first time length, and the preset first time length is the frequency increase maintenance time length, etc., which is customized by the household appliance or the user according to actual needs, and the present disclosure does not limit it.

[0051] When the above-mentioned anti-fluctuation control includes the maintenance time control of the frequency limiting protection, if the household appliance detects the frequency reduction protection for the compressor, the operating frequency of the compressor can be reduced, and the operating frequency after the frequency reduction processing can be maintained within the preset second time period. Among them, the operating frequency after the frequency reduction processing is also outside the above-mentioned shielding frequency range, which can also be called a non-shielded frequency (point), etc. The preset second time period can also be the frequency reduction maintenance time period, etc., which is customized by the household appliance or the user according to actual needs, and the present disclosure does not limit it.

[0052] It is understandable that the present disclosure does not limit the specific implementation of the compressor frequency reduction protection detection, for example, it can be detected by parameters such as the compressor exhaust temperature, external tube temperature and working current. Specifically, when the compressor exhaust temperature is too high, the external tube temperature is too high or the working current is too high, the compressor frequency reduction protection can be triggered, so that the compressor frequency reduction protection can be detected; otherwise, it is determined that the compressor frequency reduction protection is not detected.

[0053] In some optional embodiments, after waiting for / passing the preset second time, the above-mentioned anti-fluctuation protection / control may be exited and the frequency increase operation may continue; that is, after exiting the above-mentioned anti-fluctuation control, the operating frequency of the above-mentioned compressor may continue to be increased. The preset second time is the frequency anti-fluctuation control time set by the household appliance or the user, and it may be any value between 10 minutes and 30 minutes.

[0054] In some other optional embodiments, the household appliance can obtain a target temperature difference, which can refer to the temperature difference of the household appliance within a preset third time, and the temperature difference refers to the difference between the actual temperature of the environment in which the household appliance is located and the preset set temperature for it. When the above target temperature difference is greater than or equal to the preset temperature, the above anti-fluctuation protection / control can be exited and the frequency increase can continue to be run; that is, after exiting the above anti-fluctuation control, the operating frequency of the above compressor can continue to be increased. The above preset third time is a time duration customized by the household appliance or the user, such as 60 seconds. The above preset temperature can also be a temperature threshold customized by the household appliance or the user according to actual conditions, such as 2°C. Taking the above preset second time as 60s and the above preset temperature as 2°C as an example, the user can adjust the set temperature of the household appliance (such as an air conditioner) so that the target temperature difference of the air conditioner can be increased by more than 2°C within 60s, and then the above anti-fluctuation protection / control process for the compressor frequency can be exited, allowing the compressor to be increased to ensure the refrigerant flow and the cooling effect of the air conditioner.

[0055] It should be noted that the above two optional embodiments can be selected according to actual conditions. Either one of the embodiments can be implemented alone, or the two can be implemented in combination. This disclosure does not make too many restrictions and details on this.

[0056] To better understand the embodiments of the present disclosure, the following examples are given. Taking the above-mentioned household appliance as an air conditioner and the above-mentioned shielding frequency range of 46Hz to 58Hz as an example, when the operating frequency of the air conditioner compressor is increased to 50Hz, the anti-freezing frequency limiting protection can be triggered. At this time, the operating frequency of the compressor needs to be reduced from 50Hz to 45Hz. If the above-mentioned frequency limiting protection is completed within the preset first time (such as 5 minutes), the above-mentioned compressor can be re-upgraded, and the anti-freezing frequency limiting protection will be triggered again. If there are three consecutive frequency limiting protections, and the operating frequency of the compressor is reduced within the above-mentioned shielding frequency range, and the time interval between the two frequency reductions (referred to as the frequency reduction interval or frequency limiting interval) is within the above-mentioned preset first time, then the anti-fluctuation protection / control can be entered. At this time, the anti-freezing frequency limiting protection for the compressor can be shielded, and the compressor can continue to be increased, for example, to 59Hz. If the anti-freezing frequency limiting protection is not triggered, the operating frequency of the compressor can be maintained at 59Hz. If the anti-freezing frequency limiting protection is triggered during the period, the operating frequency of the compressor can be reduced to 45HZ. When the preset second time has passed or the target temperature difference increases by more than 2°C within 60 seconds, the above-mentioned anti-fluctuation protection / control process can be allowed to be exited, and the compressor can continue to be allowed to increase the frequency.

[0057] By implementing the embodiments of the present disclosure, the frequency limiting protection can be triggered multiple times in succession during the frequency increase process of the compressor. At the same time, after passing through the above-mentioned shielding frequency range, the frequency anti-fluctuation protection / control can be entered to avoid the air conditioner from experiencing temperature fluctuations, poor noise, and other problems that affect user comfort. In a specific implementation, the household appliance obtains a frequency limiting parameter, which is a working parameter that triggers the compressor to perform frequency limiting protection within a preset first time during the frequency increase phase; when the frequency limiting parameter meets the preset conditions, the operating frequency of the compressor is subjected to anti-fluctuation control. It can be seen that the household appliance triggers the compressor to perform frequency limiting protection during the frequency increase process, and when the frequency limiting parameter meets the preset conditions, frequency anti-fluctuation control can be performed to avoid the technical problems such as temperature fluctuations, poor noise, and impact on user comfort that exist in the above-mentioned related technologies, thereby helping to improve the user experience and increase the user stickiness of the product.

It can be seen that the compressor can be triggered to perform frequency limiting protection during the frequency increasing process, and the frequency anti-fluctuation control can be performed when the frequency limiting parameter is within the corresponding preset range, so as to avoid the technical problems such as temperature fluctuation, noise difference, and impact on user comfort existing in the above-mentioned related technologies, thereby helping to improve the user experience and increase the user stickiness of the product.
