Description

用于滤网清洁的方法及装置、家电设备、存储介质
本申请基于申请号为202111216284.4、申请日为2021年10月19日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及智能家电技术领域，例如涉及一种用于滤网清洁的方法及装置、家电设备、存储介质。
背景技术
目前，空调器都设置有过滤网。而随着使用时间的增加，过滤网会积聚大量的灰尘，使得空调器室内机中空气流通变差。空调器出风口风量变小，相应的制冷效果也会随之下降，甚至导致空调器吹向室内的风中带有灰尘。
现有技术中为解决上述问题通常采用光敏传感器检测是否存在灰尘堵塞过滤网的情况，而对于被堵塞滤网的清洁方式一般为提示用户手动清洁或通过预装在室内机中的吸尘器和喷洒等清洗设备来进行自动清洁。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
光敏传感器检测是否存在灰尘堵塞过滤网时，会存在由于过滤网的部分区域堵塞严重而误判为整体堵塞严重的情况，判定过滤网堵塞的精准度较低。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供了一种用于滤网清洁的方法及装置、家电设备、存储介质，以提高判定过滤网堵塞的精准度。
在一些实施例中，上述方法包括：获取风道内的静压值；在静压值小于设定阈值的情况下，运行除尘操作；在静压值大于或等于设定阈值的情况下，停止运行除尘操作，运行清洗操作。
在一些实施例中，上述装置包括：处理器和存储有程序指令的存储器，处理器被配置 为在运行程序指令时，执行上述的用于滤网清洁的方法。
在一些实施例中，上述家电设备包括：如上述的用于滤网清洁的装置。
在一些实施例中，上述存储介质，存储有程序指令，上述程序指令在运行时，执行上述的用于滤网清洁的方法。
本公开实施例提供的用于滤网清洁的方法及装置、家电设备、存储介质，可以实现以下技术效果：
通过空调器室内机风道中的静压值，来判断过滤网的堵塞情况。在过滤网基本完全堵塞的情况下，风道内会出现真空的状态。此时，控制空调器对滤网上的灰尘进行清理。并在清理完成后对滤网表面进行洗涤，避免有残余的灰尘遗留。由于只有在过滤网整体堵塞到一定程度的情况下，才会出现真空状态，因此避免了由于部分堵塞所导致的频繁清洗情况的出现，提高了判定过滤网堵塞的精准度。
以上的总体描述和下文中的描述仅是示例性和解释性的，不用于限制本申请。

结合图1所示，本公开实施例提供一种用于滤网清洁的方法，包括：
S01，家电设备获取风道内的静压值。
S02，家电设备在静压值小于设定阈值的情况下，运行除尘操作。
S03，家电设备在静压值大于或等于设定阈值的情况下，停止运行除尘操作，运行清洗操作。
采用本公开实施例提供的用于滤网清洁的方法，能通过空调器室内机风道中的静压值，来判断过滤网的堵塞情况。在过滤网基本完全堵塞的情况下，风道内会出现真空的状态。此时，控制空调器对滤网上的灰尘进行清理。并在清理完成后对滤网表面进行洗涤，避免有残余的灰尘遗留。由于只有在过滤网整体堵塞到一定程度的情况下，才会出现真空状态，因此避免了由于部分堵塞所导致的频繁清洗情况的出现，提高了判定过滤网堵塞的精准度。
结合图2所示，本公开实施例提供一种用于滤网清洁的方法，包括：
S01，家电设备获取风道内的静压值。
S021，家电设备在静压值小于设定阈值的情况下，控制压缩机的运行频率降至最低运行频率。
S022，家电设备控制贯流风扇按照除尘周期运行直至静压值大于或等于设定阈值。
采用本公开实施例提供的用于滤网清洁的方法，能通过贯流风扇按照相应的周期运行，将过滤网上的灰尘吹离过滤网。从而可以利用贯流风扇达到除尘的技术效果，无需在室内机中额外设置吸尘设备。或者是使其不是牢固的固定在过滤网上，便于后面运行清洗操作时，可以使灰尘可以被顺利清洗掉。控制压缩机的运行频率降至最低运行频率可以保证家电设备的运行满足最低的使用需求，避免了由于滤网的清洁过程所导致的无法满足用 户使用需求情况的出现。
可选地，家电设备控制贯流风扇按照除尘周期运行，包括：控制贯流风扇反转第一预设时长；控制贯流风扇正转第二预设时长；其中，除尘周期为第一预设时长与第二预设时长之和。
这样，能更好地通过贯流风扇的正反转来实现过滤网上的灰尘的清洁。由于破坏物体连接的最好方式是通过不同方向的力来削弱其连接的强度，因此通过贯流风扇的正反转来施加两个方向的力到过滤网上的灰尘来破坏其与过滤网的连接关系。通过贯流风扇的反转将过滤网上的附着物吹离过滤网，而后通过贯流风扇的正转将较小的灰尘吸入蒸发器。例如：控制贯流风扇反转30s，将过滤网中的附着物吹浮或吹出空调室内机。然后控制风扇恢复正转5分钟，将体积较小的灰尘或未被吹出室内机的灰尘吸入蒸发器以通过后续的清洗操作将其带出室内机。通过贯流风扇周期性的正反转来实现过滤网上的灰尘从过滤网上脱离，降低了在室内机中额外设置吸尘设备一类的其他除尘方式所带来的成本提升，也降低了在室内机中额外设置吸尘设备一类的其他除尘方式所带来的较高故障率。
结合图3所示，本公开实施例提供一种用于滤网清洁的方法，包括：
S01，家电设备获取风道内的静压值。
S02，家电设备在静压值小于设定阈值的情况下，运行除尘操作。
S031，家电设备在静压值大于或等于设定阈值的情况下，控制压缩机运行频率提升至自清洁频率。
S032，家电设备在满足预设条件的情况下，控制贯流风扇开启并控制压缩机的运行频率降至设定频率。
采用本公开实施例提供的用于滤网清洁的方法，能通过静压值来判定过滤网上的灰尘量。在判定到大部分灰尘与过滤网脱节之后，可以控制家电设备停止运行除尘操作，转而将吸至换热器的灰尘通过运行清洗操作带离家电设备。例如，在贯流风扇连续运行至第3个除尘周期时，检测到的静压值大于或等于设定阈值。此时贯流风扇执行完当前的除尘周期后家电设备停止除尘操作，并控制压缩机开始升频至与室外环境温度相对应的压缩机频率。在压缩机的运行频率达到与室外环境温度相对应的压缩机频率后，再将运行频率提升至当前频率的105％并维持提升后的频率运行。这种运行方式，能够使蒸发器表面迅速结霜。又因为冰的密度较小，因此结霜之后，水的体积变大，能让蒸发器表面的灰尘剥离换热管。在达到一定预设条件的情况下，控制贯流风扇开启进行化霜同时压缩机恢复运行频率至与室外环境温度相对应的压缩机频率，避免在化霜的过程中持续结霜。这样一来，化霜后灰尘就随着冷凝水被排出家电设备，从而提高了蒸发器表面的洁净程度。
可选地，家电设备满足的预设条件，包括：除霜传感器的温度值小于或等于预设温度值。
这样，能更好地通过读取传感器的检测值来判断是否需要停止，实现了控制的精准性，最大限度的保证了家电设备能耗的最小化。例如，除霜传感器检测到的温度值小于0度的情况下，判定为表面已经完全结霜。灰尘随着水结冰后体积的增大被带离蒸发器的表面，此时开启化霜进程降低压缩机运行频率同时开启贯流风扇化霜。这样一来，化霜后灰尘就随着冷凝水被排出家电设备，从而提高了蒸发器表面的洁净程度。
可选地，家电设备满足的预设条件，包括：压缩机以自清洁频率运行的运行时长达到设定时长。
这样，能更好地通过压缩机的运行时长来判断是否需要停止，降低了家电设备使用的故障率，保证了家电设备运行的稳定性。例如，压缩机以自清洁频率运行的运行时长达到3分钟的情况下，判定为表面已经完全结霜。灰尘随着水结冰后体积的增大被带离蒸发器的表面，此时开启化霜进程降低压缩机运行频率同时开启贯流风扇化霜。这样一来，化霜后灰尘就随着冷凝水被排出家电设备，从而提高了蒸发器表面的洁净程度。
可选地，家电设备满足的预设条件，包括：除霜传感器的温度值小于或等于预设温度值，且压缩机以自清洁频率运行的运行时长达到设定时长。
这样，能更好地通过读取传感器的值以及压缩机的运行时长，双重保障来判断是否需要停止结霜的过程，避免了单一组件误判所带来的除霜不完全的可能。例如，除霜传感器检测到的温度值小于0度且压缩机以自清洁频率运行的运行时长达到3分钟的情况下，判定为表面已经完全结霜。灰尘随着水结冰后体积的增大被带离蒸发器的表面，此时开启化霜进程降低压缩机运行频率同时开启贯流风扇化霜。这样一来，化霜后灰尘就随着冷凝水被排出家电设备，从而提高了蒸发器表面的洁净程度。
结合图4所示，本公开实施例提供一种用于滤网清洁的方法，包括：
S01，家电设备获取风道内的静压值。
S02，家电设备在静压值小于设定阈值的情况下，运行除尘操作。
S03，家电设备在静压值大于或等于设定阈值的情况下，停止运行除尘操作，运行清洗操作。
S04，家电设备控制地面清洁设备进入设定范围内。
S05，家电设备控制地面清洁设备清理设定范围内的地面环境。
采用本公开实施例提供的用于滤网清洁的方法，能通过智能家居系统的关联关系，调用家中的地面清洁设备将贯流风扇在运行除尘操作时吹出家电设备的灰尘进行处理。由于 本公开实施离例是采用检测家电设备内部的静压值，因此在贯流风扇除尘的过程中可能会吹出大量的灰尘到地面上。此时通过调用地面清洁设备进入灰尘可能落入的范围内进行地面的清理工作，无需用户自行清理，提升了用户的使用体验。
结合图5所示，本公开实施例提供一种用于滤网清洁的方法，包括：
S01，家电设备获取风道内的静压值。

S03，家电设备在静压值大于或等于设定阈值的情况下，停止运行除尘操作，运行清洗操作。
采用本公开实施例提供的用于滤网清洁的方法，能通过一定的时长限制贯流风扇的运行时长来判断家电设备是否存在故障。通过实验得出一个贯流风扇在不同情况下所满足的不同清洁时长(例如：在高温潮湿的情况日常使用，在低温干燥的情况下一定时间没有使用等不同使用情况)，在超出该清洁时长且仍未触发停止运行除尘操作的满足条件的情况下，判定可能存在组件故障。此时，控制贯流风扇停止运行避免不必要的能源消耗，并提示用户设备故障。其中，故障设备可能是贯流风扇不能正常运行导致灰尘未被去除，也可能是静压传感器故障导致的读数异常或无法读数等情况。
可选的，家电设备在运行时长大于或等于清洁时长的情况下，控制贯流风扇停止运行并提示用户需要手动清洁。
这样，能更好地通过一定的时长限制贯流风扇的运行时长来判断过滤网上的灰尘是否可以通过家电设备的自清洁方式清除。通过实验得出一个贯流风扇在不同情况下所满足的不同清洁时长，在超出该清洁时长且仍未触发停止运行除尘操作的满足条件的情况下，判定家电设备无法自行完成清洁过程。此时，控制贯流风扇停止运行避免不必要的能源消耗，并提示用户需要手动清洁。
可选的，提示用户设备故障可以是通过空调直接发出提示信息的方式实现；例如，家电设备的显示屏上有字幕提示，或者，家电设备发出一定的音频提示。提示用户设备故障也可以是通过空调与用户的关联设备无线连接的方式实现；例如，通过关联设备的APP应用向用户发送提示信息。其中，关联设备可以为用户的手机或智能手表等智能穿戴设备。可选地，提示用户设备故障也可以是上述多种方式的自由组合。
