如图1所示，根据本申请第一方面实施例的空调的自清洁模式保护方法，包括：As shown in FIG1 , a self-cleaning mode protection method for an air conditioner according to an embodiment of the first aspect of the present application includes:
步骤S1，接收到空调进入自清洁模式的指令，控制空调进入自清洁模式；Step S1, receiving an instruction for the air conditioner to enter a self-cleaning mode, and controlling the air conditioner to enter the self-cleaning mode;
步骤S2，判断空调在自清洁模式内所处的当前运行阶段，并根据当前运行阶段，选择获取室内换热器的室内盘管温度或者室外换热器的室外盘管温度；Step S2, determining the current operation stage of the air conditioner in the self-cleaning mode, and selecting to obtain the indoor coil temperature of the indoor heat exchanger or the outdoor coil temperature of the outdoor heat exchanger according to the current operation stage;
步骤S3，根据室内盘管温度或者室外盘管温度，并根据当前运行阶段，调节压缩机的工作参数。 Step S3, adjusting the operating parameters of the compressor according to the indoor coil temperature or the outdoor coil temperature and the current operation stage.
根据本申请实施例的空调的自清洁模式保护方法，其具体工作过程如下：首先，在控制器接收到空调进入自清洁模式的指令后，控制器控制空调进入自清洁模式以对室内换热器和室外换热器进行清洁。在空调运行自清洁模式的过程中，控制器判断当前空调在自清洁模式内所处的运行阶段，当空调当前处于不同的运行阶段时，控制器获取不同的温度参数，并在后续的控制中基于上述获取到的温度参数，对压缩机的工作参数进行调节。According to the self-cleaning mode protection method of the air conditioner in the embodiment of the present application, the specific working process is as follows: First, after the controller receives the instruction for the air conditioner to enter the self-cleaning mode, the controller controls the air conditioner to enter the self-cleaning mode to clean the indoor heat exchanger and the outdoor heat exchanger. During the process of the air conditioner running in the self-cleaning mode, the controller determines the current operating stage of the air conditioner in the self-cleaning mode. When the air conditioner is currently in different operating stages, the controller obtains different temperature parameters, and in subsequent control, adjusts the operating parameters of the compressor based on the above-obtained temperature parameters.
其中，以自清洁模式的运行阶段包括凝霜阶段和除霜阶段为例进行说明，则当空调处于凝霜阶段时，控制器获取室内换热器的盘管温度(简称室内盘管温度)，并基于上述室内盘管温度的具体大小对压缩机的工作参数进行调节；当空调处于除霜阶段时，控制器获取室外换热器的盘管温度(简称室外盘管温度)，并基于上述室外盘管温度的具体大小对压缩机的工作参数进行调节。Among them, taking the operating stages of the self-cleaning mode including the frost stage and the defrost stage as an example, when the air conditioner is in the frost stage, the controller obtains the coil temperature of the indoor heat exchanger (referred to as the indoor coil temperature), and adjusts the working parameters of the compressor based on the specific size of the above indoor coil temperature; when the air conditioner is in the defrost stage, the controller obtains the coil temperature of the outdoor heat exchanger (referred to as the outdoor coil temperature), and adjusts the working parameters of the compressor based on the specific size of the above outdoor coil temperature.
一般的，现有技术中空调的清洁方法主要包括人工清理和空调自清洁两种方式，其中，空调自清洁的方式主要分为凝霜阶段和化霜阶段，其中，以分体式空调的室内机为例，在凝霜阶段，空调先以制冷模式运行，并加大对室内换热器的冷媒输出量，从而使室内空气中的水分可以逐渐在换热器的外表面凝结成霜或冰层，这一过程中，凝结的冰霜层可以与灰尘向结合，从而将灰尘从换热器外表面剥离；之后，在化霜阶段，空调以制热模式运行，使换热器外表面所凝结的冰霜层融化，灰尘也会随着融化的水流汇集至接水盘中，这样，就可以实现对空调室内机的自清洁目的；同理，在对分体式空调的室外机进行清洁时，则按照与室内机相反的流程进行自清洁操作，即空调先运行制热模式(室外机温度降低，冰霜凝结)之后再运行制冷模式(室外机温度升高，冰霜融化)。Generally, the cleaning methods of air conditioners in the prior art mainly include two methods: manual cleaning and air conditioner self-cleaning. Among them, the air conditioner self-cleaning method is mainly divided into a frost stage and a defrost stage. Taking the indoor unit of a split air conditioner as an example, in the frost stage, the air conditioner first operates in a cooling mode and increases the refrigerant output to the indoor heat exchanger, so that the moisture in the indoor air can gradually condense into frost or ice on the outer surface of the heat exchanger. In this process, the condensed frost layer can combine with dust, thereby peeling the dust from the outer surface of the heat exchanger; thereafter, in the defrost stage, the air conditioner operates in a heating mode to melt the frost layer condensed on the outer surface of the heat exchanger, and the dust will also be collected in the water receiving tray with the melted water flow, so that the purpose of self-cleaning of the indoor unit of the air conditioner can be achieved; similarly, when cleaning the outdoor unit of the split air conditioner, the self-cleaning operation is performed according to the opposite process of the indoor unit, that is, the air conditioner first operates in a heating mode (the temperature of the outdoor unit decreases, the frost condenses) and then operates in a cooling mode (the temperature of the outdoor unit increases, the frost melts).
然而，上述现有技术中的空调自清洁方式中并没有设置对室内换热器的盘管或者室外换热器的盘管进行盘管温度保护的程序，因此对自清洁模式下的空调的保护不够完善，极易出现盘管温度过高或者过低的情况，并且上述极端情况往往会导致室内机或者室外机的故障的发生，进而影响空调的自清洁效果，以及影响空调后续的正常制冷过程和正常制热过程。However, the air conditioner self-cleaning method in the above-mentioned prior art does not have a program for coil temperature protection of the coil of the indoor heat exchanger or the coil of the outdoor heat exchanger. Therefore, the protection of the air conditioner in the self-cleaning mode is not perfect, and it is very easy for the coil temperature to be too high or too low. The above extreme situations often lead to malfunctions of the indoor unit or the outdoor unit, thereby affecting the self-cleaning effect of the air conditioner, as well as the subsequent normal cooling process and normal heating process of the air conditioner.
为了解决上述相关技术中的技术缺陷，本申请提出了一种空调的自清洁模式保护方法，该方法在空调运行自清洁模式时加入了盘管温度保护程 序，通过在自清洁模式的不同的运行阶段下获取不同的温度参数，并基于该温度参数对压缩机的工作参数进行调整，可以使得空调的盘管温度(包括室内盘管温度和室外盘管温度)在自清洁模式的不同运行阶段均能稳定在一个安全范围内，从而实现自清洁模式下对于盘管温度的保护，避免出现因盘管温度过高或过低而导致空调故障的问题，保证空调的自清洁效果，并且延长了室内换热器和室外换热器的使用寿命，进而延长了空调的使用寿命。In order to solve the technical defects in the above-mentioned related technologies, the present application proposes a self-cleaning mode protection method for an air conditioner, which adds a coil temperature protection process when the air conditioner is running in the self-cleaning mode. By obtaining different temperature parameters in different operating stages of the self-cleaning mode and adjusting the working parameters of the compressor based on the temperature parameters, the coil temperature of the air conditioner (including the indoor coil temperature and the outdoor coil temperature) can be stabilized within a safe range in different operating stages of the self-cleaning mode, thereby realizing the protection of the coil temperature in the self-cleaning mode, avoiding the problem of air conditioner failure caused by excessively high or low coil temperature, ensuring the self-cleaning effect of the air conditioner, and extending the service life of the indoor heat exchanger and the outdoor heat exchanger, thereby extending the service life of the air conditioner.
根据本申请的一些实施例，在步骤S1中：对于控制器所接收到的空调进入自清洁模式的指令而言，该指令可以为用户从外界输入的指令，例如，用户通过操作空调面板上的按钮或者旋钮，向控制器发出控制空调进入自清洁模式的指令；或者，该指令也可以为系统基于预设判断条件的满足而向控制器自动发出的指令，例如，当系统检测到空调满足预设判断条件时，系统向控制器发出控制空调进入自清洁模式的指令。According to some embodiments of the present application, in step S1: for the instruction received by the controller to enter the air conditioner self-cleaning mode, the instruction may be an instruction input by the user from the outside, for example, the user sends an instruction to the controller to control the air conditioner to enter the self-cleaning mode by operating a button or knob on the air conditioner panel; or, the instruction may also be an instruction automatically issued by the system to the controller based on the satisfaction of a preset judgment condition, for example, when the system detects that the air conditioner meets the preset judgment condition, the system sends an instruction to the controller to control the air conditioner to enter the self-cleaning mode.
在一些具体实施例中，上述预设判断条件可以为空调的累计运行时长、盘管温度或者盘管的结垢程度等条件。例如，系统检测到空调的累计运行时长达到设定的累计时长阈值后，系统向控制器下发控制空调进入自清洁模式的指令。又例如，本方法在步骤S1之前还包括：控制空调以预设的基准参数运行，获取换热器的当前盘管温度；根据当前盘管温度和预设的基准盘管温度的比较结果，确定空调的换热器的结垢程度；基于结垢程度判断是否满足自清洁模式的触发条件。In some specific embodiments, the above-mentioned preset judgment conditions may be conditions such as the accumulated running time of the air conditioner, the coil temperature, or the scaling degree of the coil. For example, after the system detects that the accumulated running time of the air conditioner reaches the set accumulated time threshold, the system sends an instruction to the controller to control the air conditioner to enter the self-cleaning mode. For another example, before step S1, the method also includes: controlling the air conditioner to operate with preset reference parameters, obtaining the current coil temperature of the heat exchanger; determining the scaling degree of the heat exchanger of the air conditioner based on the comparison result of the current coil temperature and the preset reference coil temperature; judging whether the triggering condition of the self-cleaning mode is met based on the scaling degree.
根据本申请的一些实施例，步骤S2具体包括：According to some embodiments of the present application, step S2 specifically includes:
确定空调在自清洁模式内处于凝霜运行阶段，获取室内盘管温度。Determine that the air conditioner is in the condensation operation stage in the self-cleaning mode and obtain the indoor coil temperature.
进一步地，在获取完室内盘管温度之后的步骤S3中，具体包括：Further, after obtaining the indoor coil temperature, step S3 specifically includes:
确定室内盘管温度低于第一设定温度，调节压缩机的工作频率设定降频逻辑进行降频；Determining that the indoor coil temperature is lower than the first set temperature, adjusting the operating frequency of the compressor and setting the frequency reduction logic to reduce the frequency;
确定室内盘管温度高于第二设定温度，调节压缩机的工作频率按照设定升频逻辑进行升频。It is determined that the indoor coil temperature is higher than the second set temperature, and the operating frequency of the compressor is adjusted to increase the frequency according to the set frequency increase logic.
在本实施例中，当空调处于凝霜运行阶段时，室外换热器制热，室内换热器制冷以实现室内换热器的盘管的凝霜过程。In this embodiment, when the air conditioner is in the condensation operation stage, the outdoor heat exchanger is used for heating and the indoor heat exchanger is used for cooling to realize the condensation process of the coil of the indoor heat exchanger.
在上述凝霜阶段中，当控制器确定室内盘管温度过低时(即低于第一 设定温度时)，控制器控制压缩机的工作频率降低，从而减少压缩机的功率，进而减少室内换热器的制冷量，使得室内换热器的温度回升至正常凝霜温度，这样，避免室内换热器因温度过低而发生故障，保证了室内换热器的正常凝霜过程，并且延长了其使用寿命。In the above condensation stage, when the controller determines that the indoor coil temperature is too low (i.e., lower than the first When the set temperature is reached, the controller controls the operating frequency of the compressor to decrease, thereby reducing the power of the compressor, and then reducing the cooling capacity of the indoor heat exchanger, so that the temperature of the indoor heat exchanger returns to the normal condensation temperature. In this way, the indoor heat exchanger is prevented from malfunctioning due to too low a temperature, the normal condensation process of the indoor heat exchanger is ensured, and its service life is extended.
在上述凝霜阶段中，当控制器确定室内盘管温度过高时(即高于第二设定温度时)，控制器控制压缩机的工作频率升高，从而提高压缩机的功率，进而增加室内换热器的制冷量，使得室内换热器的温度可以满足室内换热器的凝霜要求，这样，避免室内换热器因温度过高而影响其凝霜效果，进而避免室内换热器因凝霜不足而导致自清洁效果较差，提高了室内换热器的自清洁效果。In the above-mentioned frost condensation stage, when the controller determines that the indoor coil temperature is too high (that is, higher than the second set temperature), the controller controls the operating frequency of the compressor to increase, thereby increasing the power of the compressor, and then increasing the cooling capacity of the indoor heat exchanger, so that the temperature of the indoor heat exchanger can meet the frost condensation requirements of the indoor heat exchanger. In this way, the indoor heat exchanger is prevented from being affected by the high temperature and its frost condensation effect, and the indoor heat exchanger is prevented from having a poor self-cleaning effect due to insufficient frost condensation, thereby improving the self-cleaning effect of the indoor heat exchanger.
在一些实施例中，上述第一设定温度可以为室内换热器在空调正常制冷模式下可达到的最低制冷温度，或者，上述第一设定温度可以为用户提前预设的温度或者系统默认设置的温度，本申请对于第一设定温度的具体大小不做特殊限制。此外，上述第二设定温度可以为用户提前预设的温度或者系统默认设置的温度，本申请对于第二设定温度的具体大小也不做特殊限制。In some embodiments, the first set temperature may be the lowest cooling temperature that the indoor heat exchanger can reach in the normal cooling mode of the air conditioner, or the first set temperature may be a temperature preset by the user in advance or a temperature set by the system by default, and the present application does not impose any special restrictions on the specific value of the first set temperature. In addition, the second set temperature may be a temperature preset by the user in advance or a temperature set by the system by default, and the present application does not impose any special restrictions on the specific value of the second set temperature.
在一些实施例中，设定降频逻辑包括：控制压缩机的工作频率以每隔第一设定时长降低第一设定频率的方式进行降频。例如，控制器控制压缩机的工作频率每隔10s降低1Hz，当然，本申请对于第一设定时长和第一设定频率的具体大小不做特殊限制，上述第一设定时长和第一设定频率也可以取除本实施例之外的其他大小。In some embodiments, setting the frequency reduction logic includes: controlling the operating frequency of the compressor to reduce the frequency by reducing the first set frequency every first set time. For example, the controller controls the operating frequency of the compressor to reduce 1 Hz every 10 seconds. Of course, the present application does not impose any special restrictions on the specific sizes of the first set time and the first set frequency. The above-mentioned first set time and the first set frequency can also take other sizes other than those in this embodiment.
设定升频逻辑包括：控制压缩机的工作频率以每隔第二设定时长升高第二设定频率的方式进行升频。例如，控制器控制压缩机的工作频率每隔10s升高1Hz，当然，本申请对于第二设定时长和第二设定频率的具体大小不做特殊限制，上述第二设定时长和第二设定频率也可以取除本实施例之外的其他大小。Setting the frequency increase logic includes: controlling the operating frequency of the compressor to increase the second set frequency every second set time. For example, the controller controls the operating frequency of the compressor to increase by 1 Hz every 10 seconds. Of course, the present application does not impose any special restrictions on the specific values of the second set time and the second set frequency. The second set time and the second set frequency may also be other values than those in the present embodiment.
此外，在上述除霜运行阶段下执行的设定降频逻辑和设定升频逻辑也可以为其他频率调节方式，例如，控制压缩机立刻下降或者提高某一预设变化频率，或者控制压缩机缓慢下降或者提高至某一目标频率等，本申请在此不做特殊限制。 In addition, the set frequency reduction logic and the set frequency increase logic executed in the above-mentioned defrost operation stage can also be other frequency adjustment methods, for example, controlling the compressor to immediately decrease or increase a preset change frequency, or controlling the compressor to slowly decrease or increase to a certain target frequency, etc. This application does not make any special restrictions here.
根据本申请的一些实施例，步骤S2具体包括：确定空调在自清洁模式内处于化霜运行阶段，获取室外盘管温度。According to some embodiments of the present application, step S2 specifically includes: determining that the air conditioner is in a defrosting operation stage in a self-cleaning mode, and obtaining an outdoor coil temperature.
进一步地，在获取到室外盘管温度之后的步骤S3中，具体包括：Further, after obtaining the outdoor coil temperature, step S3 specifically includes:
确定室外盘管温度低于第三设定温度，调节压缩机的工作频率按照设定降频逻辑进行降频；Determining that the outdoor coil temperature is lower than the third set temperature, adjusting the operating frequency of the compressor to reduce the frequency according to the set frequency reduction logic;
确定室外盘管温度高于第四设定温度，调节压缩机的工作频率按照设定升频逻辑进行升频。It is determined that the outdoor coil temperature is higher than the fourth set temperature, and the operating frequency of the compressor is adjusted to increase the frequency according to the set frequency increase logic.
在本实施例中，当空调处于化霜运行阶段时，室外换热器制冷，室内换热器制热以实现室内换热器的盘管的化霜过程，从而利用凝霜后的化霜过程清理掉室内换热器上的污垢，实现自清洁。In this embodiment, when the air conditioner is in the defrosting operation stage, the outdoor heat exchanger cools and the indoor heat exchanger heats to realize the defrosting process of the coil of the indoor heat exchanger, thereby utilizing the defrosting process after condensation to clean the dirt on the indoor heat exchanger and realize self-cleaning.
在上述化霜阶段中，当控制器确定室外盘管温度过低时(即低于第三设定温度时)，控制器控制压缩机的工作频率降低，从而减少压缩机的功率，这样，一方面，减少了室外换热器的制冷量，使得室外换热器的温度回升至正常化霜温度，避免室外换热器因温度过低而发生故障，延长了其使用寿命，另一方面，减小了室内换热器的制热量，使得室内换热器的温度降低至正常化霜温度，避免室内换热器因温度过高而发生故障，延长了其使用寿命，并且保证了室内换热器的正常化霜过程。In the above-mentioned defrost stage, when the controller determines that the outdoor coil temperature is too low (i.e., lower than the third set temperature), the controller controls the operating frequency of the compressor to decrease, thereby reducing the power of the compressor. In this way, on the one hand, the cooling capacity of the outdoor heat exchanger is reduced, so that the temperature of the outdoor heat exchanger returns to the normal defrost temperature, thereby avoiding the outdoor heat exchanger from malfunctioning due to excessively low temperature and extending its service life. On the other hand, the heating capacity of the indoor heat exchanger is reduced, so that the temperature of the indoor heat exchanger is reduced to the normal defrost temperature, thereby avoiding the indoor heat exchanger from malfunctioning due to excessively high temperature and extending its service life, and ensuring the normal defrost process of the indoor heat exchanger.
在上述化霜阶段中，当控制器确定室外盘管温度过高时(即高于第四设定温度时)，控制器控制压缩机的工作频率升高，从而提高压缩机的功率，这样，一方面，增加了室外换热器的制冷量，另一方面，增加了室内换热器的制热量，避免室内换热器因温度过低而影响其化霜效果，进而避免室内换热器因化霜不足而导致自清洁效果较差，提高了室内换热器的自清洁效果。In the above-mentioned defrost stage, when the controller determines that the outdoor coil temperature is too high (that is, higher than the fourth set temperature), the controller controls the operating frequency of the compressor to increase, thereby increasing the power of the compressor. In this way, on the one hand, the cooling capacity of the outdoor heat exchanger is increased, and on the other hand, the heating capacity of the indoor heat exchanger is increased, thereby avoiding the indoor heat exchanger from being affected by the defrosting effect due to the low temperature, thereby avoiding the poor self-cleaning effect of the indoor heat exchanger due to insufficient defrosting, and improving the self-cleaning effect of the indoor heat exchanger.
在一些实施例中，上述第三设定温度可以为室外换热器在空调正常制冷模式下可达到的最低制冷温度，或者，上述第三设定温度可以为用户提前预设的温度或者系统默认设置的温度，本申请对于第三设定温度的具体大小不做特殊限制。此外，上述第四设定温度可以为用户提前预设的温度或者系统默认设置的温度，本申请对于第四设定温度的具体大小也不做特殊限制。In some embodiments, the third set temperature may be the lowest cooling temperature that the outdoor heat exchanger can reach in the normal cooling mode of the air conditioner, or the third set temperature may be a temperature preset by the user in advance or a temperature set by the system by default, and the present application does not impose any special restrictions on the specific value of the third set temperature. In addition, the fourth set temperature may be a temperature preset by the user in advance or a temperature set by the system by default, and the present application does not impose any special restrictions on the specific value of the fourth set temperature.
在一些实施例中，设定降频逻辑包括：控制压缩机的工作频率以每隔 第三设定时长降低第三设定频率的方式进行降频。例如，控制器控制压缩机的工作频率每隔10s降低1Hz，当然，本申请对于第三设定时长和第三设定频率的具体大小不做特殊限制，上述第三设定时长和第三设定频率也可以取除本实施例之外的其他大小。In some embodiments, setting the frequency reduction logic includes: controlling the operating frequency of the compressor to The frequency is reduced by reducing the third set frequency by the third set time.

For example, the controller controls the operating frequency of the compressor to increase by 1 Hz every 10 seconds. Of course, the present application does not impose any special restrictions on the specific sizes of the fourth set time and the fourth set frequency, and the fourth set time and the fourth set frequency may also be other sizes than those in the present embodiment.
此外，在上述除霜运行阶段下执行的设定降频逻辑和设定升频逻辑也可以为其他频率调节方式，例如，控制压缩机立刻下降或者提高某一预设变化频率，或者控制压缩机缓慢下降或者提高至某一目标频率等，本申请在此不做特殊限制。In addition, the set frequency reduction logic and the set frequency increase logic executed in the above-mentioned defrost operation stage can also be other frequency adjustment methods, for example, controlling the compressor to immediately decrease or increase a preset change frequency, or controlling the compressor to slowly decrease or increase to a certain target frequency, etc. This application does not make any special restrictions here.
根据本申请的一个实施例，在步骤S1之后，空调的自清洁模式保护方法还包括：控制空调解除对压缩机的回油频率的限制；和/或，判断空调是否运行防冻结保护模式或者过负荷保护模式，若是，则关闭防冻结保护模式或者过负荷保护模式。According to one embodiment of the present application, after step S1, the self-cleaning mode protection method of the air conditioner also includes: controlling the air conditioner to lift the restriction on the oil return frequency of the compressor; and/or, determining whether the air conditioner is running an anti-freeze protection mode or an overload protection mode, and if so, turning off the anti-freeze protection mode or the overload protection mode.
例如，在空调进入自清洁模式之前，系统解除对于压缩机回油频率的限制，也即在空调的自清洁模式下，压缩机的回油频率不被特殊限制；此外，系统将会屏蔽盘管的防冻结保护模式以及空调的过负荷保护模式，并在空调正处于防冻结保护模式或者过负荷保护模式时关闭防冻结保护模式或者过负荷保护模式。For example, before the air conditioner enters the self-cleaning mode, the system lifts the restriction on the oil return frequency of the compressor, that is, in the self-cleaning mode of the air conditioner, the oil return frequency of the compressor is not specially restricted; in addition, the system will shield the anti-freeze protection mode of the coil and the overload protection mode of the air conditioner, and turn off the anti-freeze protection mode or the overload protection mode when the air conditioner is in the anti-freeze protection mode or the overload protection mode.
根据本申请的一个实施例，在步骤S1之后，空调的自清洁模式保护方法还包括：确定空调进入自清洁模式之后，接收其他模式下的清洁信号，但是不刷新空调在当前的自清洁模式下的运行时间。According to one embodiment of the present application, after step S1, the self-cleaning mode protection method of the air conditioner further includes: after determining that the air conditioner enters the self-cleaning mode, receiving a cleaning signal in other modes, but not refreshing the running time of the air conditioner in the current self-cleaning mode.
进一步地，在本方法中，外环温度判定仅在自清洁模式启动时判断一次，之后的运行过程便不再判定。Furthermore, in the present method, the outer ring temperature is determined only once when the self-cleaning mode is started, and no determination is made during the subsequent operation.
进一步地，在空调的自清洁模式运行的过程中，系统对与除霜相关的压缩机运行时长和除霜间隔时间不计时。Furthermore, during the operation of the air conditioner in the self-cleaning mode, the system does not count the compressor operation time and the defrost interval time associated with defrosting.
根据本申请的一些实施例，在空调进入自清洁模式并运行一段时间后， 空调退出自清洁模式，此时空调退出自清洁模式的原因包括多种。例如，空调出现故障，从而系统强制退出自清洁模式；又例如，当检测到空调的自清洁完成后，系统退出自清洁模式；又例如，系统接收到控制空调退出自清洁模式的外界指令，空调退出自清洁模式。According to some embodiments of the present application, after the air conditioner enters the self-cleaning mode and runs for a period of time, The air conditioner exits the self-cleaning mode. There are many reasons why the air conditioner exits the self-cleaning mode. For example, the air conditioner fails, so the system forces the air conditioner to exit the self-cleaning mode; for example, when the air conditioner detects that the self-cleaning is completed, the system exits the self-cleaning mode; for example, the system receives an external command to control the air conditioner to exit the self-cleaning mode, and the air conditioner exits the self-cleaning mode.
在本申请的一个实施例中，空调的自清洁模式保护方法还包括：In one embodiment of the present application, the self-cleaning mode protection method of the air conditioner further includes:
确定空调的室内机和室外机中的至少一个出现故障，或者，接收到自清洁模式结束的指令，控制空调退出自清洁模式。It is determined that at least one of the indoor unit and the outdoor unit of the air conditioner fails, or an instruction to end the self-cleaning mode is received, and the air conditioner is controlled to exit the self-cleaning mode.
在本申请的又一个实施例中，空调的自清洁模式保护方法还包括：In another embodiment of the present application, the self-cleaning mode protection method of the air conditioner further includes:
确定空调自清洁完成后，控制空调退出自清洁模式。After confirming that the air conditioner has completed self-cleaning, control the air conditioner to exit self-cleaning mode.
其中，系统可以通过检测空调的自清洁模式运行时长是否达到设定运行时长以判断空调是否完成自清洁，或者，系统也可以通过检测室内换热器的盘管上的结垢程度以判断空调是否完成自清洁，例如，当系统检测到室内换热器盘管上结垢程度低于最低设定标准，则确定空调完成自清洁，此时控制空调退出自清洁模式；当系统检测到室内换热器盘管的结构程度高于最低设定标准，则确定空调未完成自清洁，此时空调继续执行自清洁模式。Among them, the system can determine whether the air conditioner has completed self-cleaning by detecting whether the running time of the self-cleaning mode of the air conditioner has reached the set running time, or the system can also determine whether the air conditioner has completed self-cleaning by detecting the degree of scaling on the coil of the indoor heat exchanger. For example, when the system detects that the scaling degree on the indoor heat exchanger coil is lower than the minimum set standard, it determines that the air conditioner has completed self-cleaning, and the air conditioner is controlled to exit the self-cleaning mode; when the system detects that the scaling degree of the indoor heat exchanger coil is higher than the minimum set standard, it determines that the air conditioner has not completed self-cleaning, and the air conditioner continues to execute the self-cleaning mode.
根据本申请的一个实施例，在控制空调退出自清洁模式的步骤之后，空调的自清洁模式保护方法还包括：According to one embodiment of the present application, after the step of controlling the air conditioner to exit the self-cleaning mode, the self-cleaning mode protection method of the air conditioner further includes:
判断空调是否运行防冻结保护模式，若是，则控制空调关闭防冻结保护模式并持续第一设定时长。Determine whether the air conditioner is running in an anti-freeze protection mode, and if so, control the air conditioner to turn off the anti-freeze protection mode and continue for a first set time.
也即在空调退出自清洁模式后的第一设定时长内不判断防冻结保护(不会进入防冻结保护模式)，其中，第一设定时长可以为30s，当然，本申请对于第一设定时长不做特殊限制，第一设定时长还可以根据具体需求而被设定为其他时长值。That is, the anti-freeze protection will not be judged within the first set time after the air conditioner exits the self-cleaning mode (the anti-freeze protection mode will not be entered), where the first set time can be 30s. Of course, this application does not impose any special restrictions on the first set time, and the first set time can also be set to other time values according to specific needs.
根据本申请的一个实施例，在控制空调退出自清洁模式的步骤之后，空调的自清洁模式保护方法还包括：According to one embodiment of the present application, after the step of controlling the air conditioner to exit the self-cleaning mode, the self-cleaning mode protection method of the air conditioner further includes:
在退出上次运行的自清洁模式后，控制空调至少间隔预设时长以进入下一次的自清洁模式。After exiting the last self-cleaning mode, the air conditioner is controlled to enter the next self-cleaning mode for at least a preset time.
这样，通过将两次自清洁运行的间隔时长控制在预设时长以上，可以避免上次自清洁运行后产生的冷量或热量影响下次自清洁运行，减小甚至 消除上次自清洁运行对下次自清洁运行的不良影响。In this way, by controlling the interval between two self-cleaning operations to be longer than the preset time, the cooling or heat generated after the last self-cleaning operation can be prevented from affecting the next self-cleaning operation, thus reducing or even Eliminate the adverse effects of the previous self-cleaning operation on the next self-cleaning operation.
例如，上述间隔的预设时长可以为5分钟，当然，本申请对于上述间隔的预设时长不做特殊限制，上述间隔的预设时长还可以根据具体需求而被设定为其他时长值。For example, the preset duration of the above interval may be 5 minutes. Of course, the present application does not impose any special restrictions on the preset duration of the above interval, and the preset duration of the above interval may also be set to other duration values according to specific needs.
根据本申请的一些实施例，当系统检测到压缩机排气故障时不锁定，仍旧正常运行自清洁模式。According to some embodiments of the present application, when the system detects a compressor exhaust failure, it is not locked and still operates in the self-cleaning mode normally.
根据本申请的一些实施例，当系统检测到室外机故障时，该故障不传室内机，也即室内机正常运行，此时在室外机停机期间，自清洁模式的运行时长继续累积且不清零。According to some embodiments of the present application, when the system detects a fault in the outdoor unit, the fault is not transmitted to the indoor unit, that is, the indoor unit operates normally. At this time, during the shutdown of the outdoor unit, the operating time of the self-cleaning mode continues to accumulate and is not cleared.
根据本申请的一些实施例，在自清洁模式下，空调的压缩机具有高负荷保护，也即当压缩机在负荷过高时自动关闭，此时室外机内的外风机不关闭。According to some embodiments of the present application, in the self-cleaning mode, the compressor of the air conditioner has high load protection, that is, the compressor automatically shuts down when the load is too high, and the outdoor fan in the outdoor unit is not shut down.
下面对本申请提供的空调的自清洁模式保护装置进行描述，下文描述的空调的自清洁模式保护装置与上文描述的空调的自清洁模式保护方法可相互对应参照。The self-cleaning mode protection device of the air conditioner provided in the present application is described below.
