本申请要求在2021年11月29日提交中国专利局、申请号为202111430849.9的中国专利申请的优先权，以上申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及抽油烟机技术领域，例如涉及一种抽油烟机的控制方法及控制系统。
背景技术
随着科学技术水平的发展与提高，家用电器对居民生活的影响也越来越大，其中，抽油烟机已成为家用电器不可或缺的一种电器设备。
相关技术中的抽油烟机智能化低，难以实现自动调节风速挡位，尤其是在自身发生故障后还继续通电运行的情况下，将会进一步损坏抽油烟机，进而影响用户的正常使用，大大地降低用户体验感受。
发明内容
本申请实施例提供一种抽油烟机的控制方法及控制系统，以实现抽油烟机自动调挡以及停机运行，保证了抽油烟机的安全可靠运行，同时使得抽油烟机更加智能化。

图3为本申请实施例提供的一种抽油烟机的控制系统的结构示意图；
图4为本申请实施例提供的另一种抽油烟机的控制系统的结构示意图；
图5为本申请实施例提供的又一种抽油烟机的控制系统的结构示意图。
具体实施方式
图1为本申请实施例提供的一种抽油烟机的控制方法的流程图，参考图1所示，主要包括以下步骤：
S101、获取抽油烟机当前的第一风速挡位和第一电机电流。
S102、判断第一电机电流是否超出第一风速挡位所对应的第一预设电流区间，第一预设电流区间为第一预设值至第二预设值构成的区间。
S103、如果第一电机电流小于第一预设值，且持续时间超过第一预设时间，控制抽油烟机的风速挡位增加一级或保持当前第一风速挡位。
S104、如果第一电机电流大于第二预设值，且持续时间超过第二预设时间，控制抽油烟机停止运行。
其中，第一预设电流区间指抽油烟机在当前风速挡位运行下，正常工作对应的第一电机电流的范围。第一预设值对应为第一电机电流的下限值，第二预设值对应为第一电机电流的上限值。对于第一预设值和第二预设值的具体设定值，本申请实施例不做特殊限定，可根据抽油烟机的实际工作情况进行设定，且第一风速挡位不同对应的第一预设电流区间不同。示例性的，抽油烟机低速运行时对应的第一预设电流区间为0.7A～1.9A。
抽油烟机的主要功能用于排烟。可以理解的是，抽油烟机可工作在不同的风速挡位下，对于不同的风速挡位，其排烟能力是不同，即风速挡位越高，其风速越大，进而抽油烟机的排烟能力越强。与此同时，在电机电流上的体现则是风速挡位越高，抽油烟机工作时的电机 电流就越大。如此，本实施例通过获取抽油烟机当前的第一风速挡位，可以确定给第一风速挡位对应的第一预设电流区间。此时，继续获取抽油烟机的第一电机电流，并将第一电机电流与该第一风速挡位对应的第一预设电流区间进行比对。如果第一电机电流小于第一预设电流区间的第一预设值，说明当前抽油烟机的第一电机电流过小，如果该第一电机电流小于第一预设电流的持续时间超过第一预设时间，可能存在排烟阻力大的情况。如此，抽油烟机将控制其风速挡位增加一级或者继续保持当前第一风速挡位。可以理解的，如果第一风速挡位为低速挡位，则增加一级，变为中速挡位或者高速挡位；如果第一风速挡位已经是最高一级的高速挡位，则保持当前第一风速挡位。此外，如果第一电机电流大于第一预设电流区间的第二预设值，说明当前抽油烟机的第一电机电流过大。如果该第一电机电流大于第二预设电流的持续时间超过第二预设时间，此时，抽油烟机的工作状态出现严重异常，需要马上停止运行，以避免抽油烟机发生烧毁或损坏。
需要说明的是，第一预设时间和第二预设时间的具体时间长度本申请实施例不做特殊限定，可根据抽油烟机的实际情况进行设定。例如，第一预设时间为5s，第二预设时间为10s，如此，通过设置合理的时间，可保证抽油烟机可靠安全地工作。
本申请实施例中，通过实时获取抽油烟机当前的第一风速挡位，如此可以确定该第一风速挡位对应的第一预设电流区间，并获取第一电机电流，将其与第一预设电流区间进行比较。其中，第一预设电流区间为第一预设值至第二预设值构成的区间，并在判定第一电机电流小于第一预设值，且持续时间超过第一预设时间，控制抽油烟机的风速挡位增加一级或保持当前第一风速挡位。如此，以增大抽油烟机的排烟能力。在判定第一电机电流大于第二预设值，且持续时间超过第二预设时间，则控制抽油烟机停止运行，以避免第一电机电流过大而损坏抽油烟机。如此，通过获取到的第一风速档位和第一电机电流，并进行判断分析，可实现抽油烟机自动调挡以及停机运行，保证了抽油烟机的安全可靠运行，同时使得抽油烟机更加智能化，提高用户的体验感受。
例如，抽油烟机的风速挡位等级至少包括低速档位、中速档位和高速档位。例如，设置抽油烟机具有多个不同的风速挡位，如此，抽油烟机根据不同的排烟需求工作在不同风速挡位下，以节约能耗。
例如，低速档位所对应的第一预设值小于中速挡位所对应的第一预设值，中速挡位所对应的第一预设值小于高速挡位所对应的第一预设值；低速挡位所对应的第二预设值小于中速挡位所对应的第二预设值，中速挡位所对应的第二预设值小于高速挡位所对应的第二预设值；高速挡位所对应的第一预设值小于低速挡位所对应的第二预设值。
例如，抽油烟机工作在不同风速挡位，其产生的第一电机电流大小不同。如此，不同第 一风速挡位对应的第一预设电流区间不同。由于第一风速挡位越低，其对应的第一电机电流越小，如此，低速挡位所对应的第一预设值小于中速挡位所对应的第一预设值，中速挡位所对应的第一预设值小于高速挡位所对应的第一预设值。同样的，低速挡位所对应的第二预设值小于中速挡位所对应的第二预设值，中速挡位所对应的第二预设值小于高速挡位所对应的第二预设值。例如，高速挡位所对应的第一预设值小于低速挡位所对应的第二预设值。可以理解的是，抽油烟机在低速挡位运行时，保持当前第一风速挡位运行的最大电机电流值大于抽油烟机在高速挡位运行时可保持当前第一风速挡位运行的最小电机电流值。说明抽油烟机在当前第一风速挡位运行时，可承受的第一电机电流的上限值(即第二预设值)是比较大的，使得抽油烟机具有更高的可靠性，同时，避免抽油烟机风速挡位频繁调节，减小使用寿命。
需要说明的是，低速档位、中速挡位和高速挡位分别对应的第一预设电流区间的具体范围，本申请实施例不做特殊限定。示例性的，低速档位所对应的第一预设电流区间可以是0.7A～1.9A，中速档位所对应的第一预设电流区间可以是0.8A～2.0A，低速档位所对应的第一预设电流区间可以是0.9A～2.1A。
例如，图2为本申请实施例提供的另一种抽油烟机的控制方法的流程图。参考图2所示，在步骤S103中，如果第一电机电流小于第一预设值，且持续时间超过第一预设时间，控制抽油烟机的风速挡位增加一级或保持当前第一风速挡位，包括以下步骤：
S1031、检测到第一风速挡位为低速挡位或者中速挡位，第一电机电流小于第一风速挡位所对应的第一预设值，且持续时间超过第一预设时间，控制抽油烟机的风速挡位增加一级。
例如，当检测到抽油烟机运行在低速挡位或者中速挡位时，实时检测第一电机电流，并将该第一电机电流与此时第一风速挡位对应的第一预设电流区间进行比对。如果判定第一电机电流小于第一预设值进行比对，说明抽油烟机当前的排烟阻力较大。由于当前的第一风速挡位不是最高的风速挡位，如此，可以通过提高抽油烟机的风速挡位来增强抽油烟机的排烟能力。换言之，如果当前的第一风速挡位为低速挡位，增将抽油烟机提高到中速挡位。如果当前的第一风速挡位为中速挡位，则将抽油烟机的风速挡位提高到高速挡位。如此，可实现抽油烟机智能化自动调挡，同时，保证抽油烟机的安全可靠运行。
示例性的，检测到第一风速挡位为中速挡位，并且中速挡位对应的第一预设电流区间为0.8A～2.0A，同时，设定第一预设时间为5s。此时，检测到第一电机电流为0.7A且持续时间大于5s，则将抽油烟机的风速挡位从中速档位增加到高速挡位，以增大抽油烟机的排烟能力。
S1032、检测到第一风速挡位为高速挡位，第一电机电流小于第一风速挡位所对应的第一预设值，且持续时间超过第一预设时间，控制抽油烟机保持当前第一风速挡位。
例如，当检测到抽油烟机已经运行到高速挡位时，如果此时获取到的第一电机电流小于 该风速挡位对应的第一预设值，则继续保持抽油烟机运行在高速挡位，以保证抽油烟机继续保持最大的排烟能力。
示例性，检测到第一风速挡位为高速挡位，并且高速挡位对应的第一预设电流区间为0.9A～2.1A，同时，设定第一预设时间为5s。此时，检测到第一电机电流为0.8A且持续时间大于5s，则继续保持抽油烟机运行在高速挡位，以保证抽油烟机继续保持最大的排烟能力。
本申请实施例还提供了一种抽油烟机的控制系统，图3为本申请实施例提供的一种抽油烟机的控制系统的结构示意图。参考图3所示，该控制系统包括：依次电连接的抽油烟机10、参数检测模块20和检测模块30，及电连接于抽油烟机10与检测模块30之间的驱动调节模块40；参数检测模块20，设置为获取抽油烟机10当前的第一风速挡位和第一电机电流；检测模块30，设置为判断第一电机电流是否超出第一风速挡位所对应的第一预设电流区间，第一预设电流区间为第一预设值至第二预设值构成的区间；驱动调节模块40，设置为在检测到第一电机电流小于第一预设值，且持续时间超过第一预设时间时，控制抽油烟机10的风速挡位增加一级或保持当前第一风速挡位；或者，在检测到第一电机电流大于第二预设值，且持续时间超过第二预设时间时，控制抽油烟机10停止运行。
本实施例中，通过参数检测模块20实时获取抽油烟机当前的第一风速挡位以及第一电机电流，并发送至检测模块30。如此，检测模块30根据获取到的第一风速档位可以确定该第一风速挡位对应的第一预设电流区间。其中，第一预设电流区间为第一预设值至第二预设值构成的区间，并将第一电机电流与第一预设电流区间进行比较。如果检测模块30检测到第一电机电流小于第一预设值，且持续时间超过第一预设时间，则由驱动调节模块40控制抽油烟机10的风速挡位增加一级或保持当前第一风速挡位，如此，以增大抽油烟机的排烟能力。如果检测模块30检测到第一电机电流大于第二预设值，且持续时间超过第二预设时间时，则由驱动调节模块40抽油烟机10停止运行，以避免第一电机电流过大而损坏抽油烟机。如此，通过参数检测模块20获取到的第一风速档位和第一电机电流，并由检测模块30进行判断分析，可通过驱动调节模块40实现抽油烟机10自动调挡以及停机运行，保证了抽油烟机10的安全可靠运行，同时使得抽油烟机10更加智能化。
例如，图4为本申请实施例提供的另一种抽油烟机的控制系统的结构示意图。参考图4所示，检测模块30包括计时组件301，计时组件301设置为在判定第一电机电流超出第一风速挡位所对应的第一预设电流区间时，开始计时。
例如，计时组件301可以是计时器，当检测模块30检测到第一电机电流超出第一风速挡位所对应的第一预设电流区间时，开始计时，并在计时时间超过第一预设时间或第二预设时间后，由检测模块30发出相应的控制指令给驱动调节模块40，由驱动调节模块40控制抽油 烟机的运行，即风速挡位调节或者停机运行等。通过设置计时组件301以避免抽油烟机由于干扰等因素造成的误操作，以提高抽油烟机工作的可靠性和安全性。
例如，继续参考图4所示，驱动调节模块40包括控制组件401，及与控制组件401分别电连接的第一开关组件402、第二开关组件403和第三开关组件404；控制组件401，设置为根据检测模块30的检测结果控制第一开关组件402、第二开关组件403和第三开关组件404的闭合或断开；第一开关组件402闭合，则驱动抽油烟机10低速挡位运行；第二开关组件403闭合，则驱动抽油烟机10中速挡位运行；第三开关组件404闭合，则驱动抽油烟机10高速挡位运行。
例如，参考图4所示，控制组件401与检测模块30电连接，第一开关组件402、第二开关组件403和第三开关组404分别与抽油烟机10电连接，控制组件401接收检测模块30发出的控制指令，并根据该控制指令控制第一开关组件402、第二开关组件403或第三开关组件404的闭合或关断。可以理解的，第一开关组件402、第二开关组件403和第三开关组件404只能有一个开关组件处于闭合状态，以使得抽油烟机10只能工作在一种风速挡位下。例如，当第一开关组件402闭合，此时第二开关组件403和第三开关组件404均断开，则抽油烟机10运行在低速挡位；同理，当二开关组件403闭合，则抽油烟机10运行在中速挡位；当三开关组件404闭合，则抽油烟机10运行在高速挡位；当控制组件401接收到停止抽油烟机运行的指令时，则控制组件401控制第一开关组件402、第二开关组件403和第三开关组件404均关断。如此，通过控制组件401控制第一开关组件402、第二开关组件403和第三开关组件404的闭合和关断，可实现抽油烟机10风速挡位自动切换，更加智能化。
例如，第一开关组件402、第二开关组件403和第三开关组件404包括继电器。其中，继电器的具体类型本申请实施例不做特殊限定，例如可以是电磁继电器，具有动作快、工作稳定、体积小以及使用寿命长等优点。
例如，图5本申请实施例提供的又一种抽油烟机的控制系统的结构示意图。参考图5所示，该系统还包括监控后台50，及与监控后台50通讯连接的云服务器60，云服务器60与检测模块30通讯连接；检测模块30，还设置为在抽油烟机10停止运行后，将抽油烟机10的异常电参数发送至云服务器60；监控后台50，设置为通过云服务器60获取抽油烟机10的异常电参数，并显示或警报。
其中，监控后台50设置为对抽油烟机10的工作状态进行监控，以及获取抽油烟机10工作时的异常电参数，并进行显示或者发出警报等，如此便于售后人员根据监控到的抽油烟机10的状态以及异常电参数提供上门检查或维修等服务。示例性的，监控后台50可以是计算机等终端设备。
云服务器60通常指运行在相同的物理硬件上的“虚拟”服务器，又称为云计算服务器或云主机，具有大量数据存储和处理能力，是一种简单高效、安全可靠、处理能力可弹性伸缩的计算服务。在本实施例中，云服务器60设置为实现数据的接收、发送与存储，即接收检测模块30发送的异常电参数并进行缓存，然后再将接收到的异常电参数发送给监控后台50。
例如，抽油烟机10的异常电参数包括电机电流。可以理解的，抽油烟机10在正常使用过程中，电机电流处于正常电流范围内，当风机出现异常时，电机电流也会出现反常，严重时，将会损坏风机的内部元件。如此，通过获取抽油烟机10的电机电流，可以快速判断抽油烟机10的工作状态，及时发现故障并发出警报，以提醒工作人员进行及时处理。
本实施例中，通过设置检测模块30通过云服务器60与监控后台50通信连接，在检测模块30检测到第一电机电流大于第二预设值后，发出指令控制驱动调节模块40驱动抽油烟机10停止运行，同时，还将此时异常电参数电机电流通过云服务器60发送给监控后台50，监控后台50根据接收到的异常电参数进行显示并警报，以提醒工作人员及时进行维修处理，提升用户的产品体验感受。
