需要说明的是, 在对吸油烟机进行热清洗时, 缺水、 管路堵塞等异常会造成加热 器 230例如蒸汽发生器的温度过高, 而加热器 230例如蒸汽发生器的温度过高有可能 造成清洗装置 200 的损坏或产生危及人身财产安全的危险。 因此, 在本发明的一个实 施例中, 在对吸油烟机进行热清洗时, 其中, 当加热器 230 的温度大于超限预设温度 值 KP时, 控制器 251控制水泵 220、 加热器 230和主电机 270关闭, 即言, 判断加热 器 230例如蒸汽发生器的温度是否大于超限温度预设值 KP, 如果否则继续热清洗, 如 果是则关闭判断蒸汽发生器提前结束热清洗进入风干吸油烟机内部水渍。 在本发明的 一个实施例中, 超限预设温度值 ΚΡ可以为 140°C ~180°C。
为保证热清洗效果, 根据判断加热器 230 例如蒸汽发生器的温度来确定水泵 220 是否抽水, 具体地, 在本发明的一个实施例中, 当加热器 230 的温度小于等于超限预 设温度值 KP且大于水泵开启温度预设值 KN时,控制器 251控制水泵 220开启,其中, KN<KP; 当加热器 230的温度小于水泵关闭温度预设值 KF时, 控制器 251控制水泵 220关闭, 其中, KF< KN。 即言, 当加热器 230例如蒸汽发生器的温度低于水泵关闭 温度预设值 KF时关闭水泵 220停止抽水,可防止此热清洗中冷水喷出而影响热清洗效 果, 水泵 220停止抽水后, 当蒸汽发生器的温度达到水泵开启温度预设值 KN时才恢 复开启水泵 220抽水, 这样能使水在蒸汽发生器内部充分气化, 以保证热清洗效果。 其中, 在本发明的一个实施例中, 超限预设温度值 KP可以为 140°C ~180°C, 水泵开启 温度预设值 KN可以为 110°C ~120°C, 水泵关闭温度预设值 KF可以为 100°C ~110°C。
也就是说, 在本发明的一个实施例中, 在对吸油烟机进行热清洗时, 其中, 当加 热器 230的温度大于超限预设温度值 KP时, 控制器 251控制水泵 220、 加热器 230和 主电机 270关闭;当加热器 230的温度小于等于超限预设温度值 KP且大于水泵开启温 度预设值 KN时, 控制器 251控制水泵 220开启, 其中, KN< KP; 当加热器 230的温 度小于水泵关闭温度预设值 KF时, 控制器 251控制水泵 220关闭, 其中, KF< KN。 其中, 在本发明的一个实施例中, 超限预设温度值 KP可以为 140°C ~180°C, 水泵开启 温度预设值 KN可以为 110°C ~120°C, 水泵关闭温度预设值 KF可以为 100°C ~110°C。 优选地, 超限预设温度值 KP为 150°C, 水泵开启温度预设值 KN为 110°C, 水泵关闭 温度预设值 KF为 100°C。
进一步地, 为使安装在主电机 270上的叶轮 310的各个部位能够得到有效清洗, 因此, 在本发明的一个实施例中, 在对吸油烟机进行热清洗时, 控制器 251 中的热清 洗周期计时器 T1和主电机点动周期计时器 T2开始计时, 其中, 当主电机点动周期计 时器 T2的计时时间小于点动有效预设值 TK2时, 控制器 251控制主电机 270开启; 当主电机点动周期计时器 T2的计时时间大于等于点动有效预设值 TK2时,控制器 251 控制主电机 270关闭。
进一步地, 在本发明的一个实施例中, 当主电机点动周期计时器 T2的计时时间大 于等于点动周期预设值 TK3时, 控制器 251清零主电机点动周期计时器 T2, 主电机点 动周期计时器 Τ2重新开始计时, 其中, ΤΚ2<ΤΚ3 ; 当热清洗周期计时器 T1 的计时 时间大于等于清洗时间预设值 TK1时, 控制器 251控制水泵 220、 加热器 230和主电 机 270关闭, 其中, ΤΚ3 <ΤΚ1。
其中, 在本发明的一个实施例中, 清洗时间预设值 TK1可以为 6分钟 ~20分钟, 点动有效预设值 ΤΚ2可以为 0.5秒〜 2秒, 且 10 ΤΚ1/ΤΚ3 70, 即 10 (清洗时间预 设值 TK1/点动周期预设值 ΤΚ3 ) 70。 优选地, 清洗时间预设值 TK1为 12分钟, 点 动有效预设值 ΤΚ2为 1秒, 点动周期预设值 ΤΚ3为 12秒, 其中, ΤΚ1/ΤΚ3=60, 符合 点动周期预设值 ΤΚ3的取值范围满足条件: 10 (清洗时间预设值 TK1/点动周期预设 值 ΤΚ3 ) 70。
具体而言, 在本发明的实施例中, 根据判断控制器 251 的主电机点动周期计时器 Τ2的值是否小于点动有效预设值 ΤΚ2来确定是否启动主电机 270, 本实施例的点动周 期预设值 ΤΚ3=12秒, 在每个点动周期的 1秒前即当主电机点动周期计时器 Τ2的值小 于点动有效预设值 ΤΚ2时启动主电机 270, 1秒后, 即当主电机点动周期计时器 Τ2的 值大于等于点动有效预设值 ΤΚ2后关闭主电机 270,当主电机点动周期计时器 Τ2的值 大于等于点动周期预设值 ΤΚ3, 主电机点动周期计时器 Τ2清零, 然后重新计时开始新 一个点动周期计时, 通过这样实现在每次热清洗期间主电机 270 多次短时间歇启动, 电机的短时间歇启动带动叶轮位置的改变, 使叶轮的各个部位能够得到有效清洗。 为 方便描述, 电机的短时间歇启动下面简称为点动, 点动周期预设值 ΤΚ3的取值范围满 足条件: 10 (清洗时间预设值 TK1/点动周期预设值 ΤΚ3) 70, 因为, 点动次数过多 会造成叶轮持续旋转吸走部分蒸汽而使热清洗效果变差, 点动次数过少会造成叶轮部 分位置的不到清洗。
在本发明的实施例中, 在对吸油烟机进行热清洗时完成之后, 加热器 230例如蒸 汽发生器内仍残留水渍, 而加热器 230例如蒸汽发生器一般为金属材质, 如果不对蒸 汽发生器内残留的水渍进行烘干, 时间长后残留的水渍、 空气、 蒸汽发生器的共同作 用会使蒸汽发生器产生氧化损坏, 因此需要烘干蒸汽发生器内部水渍。
具体地, 在本发明的一个实施例中, 在烘干加热器 230时, 当加热器 230的温度 大于烘干温度预设值 KD时, 控制器 251控制加热器 230关闭。 其中, 在本发明的一 个实施例中, 烘干温度预设值 KD可以为 130°C ~150°C。 优选地, 烘干温度预设值 KD 为 150°C。
也就是说, 在烘干加热器 230例如蒸汽发生器内部水渍中, 通过判断蒸汽发生器 的温度是否大于烘干温度预设值 KD, 来确定是否开启蒸汽发生器, 直到蒸汽发生器的 温度大于烘干温度预设值 KD 才关闭蒸汽发生器, 本实施例中的烘干温度预设值 KD 为 15CTC,远高于水的沸腾温度 100°C,能有效保证蒸汽发生器内仍残留水渍得到烘干。
在本发明的实施例中, 在对吸油烟机进行热清洗时完成之后, 蒸汽会在清洗叶轮 310、 滤网 340等金属部件冷凝形成水渍, 而水渍的存在一方面滋生细菌, 另一方面叶 轮 310、滤网 340等金属部件在水渍与空气的共同作用下会氧化生锈, 因此需要风干吸 油烟机内部水渍。
具体地, 在本发明的一个实施例中, 在风干吸油烟机时, 控制器 251 中的风干水 渍周期计时器 T3开始计时, 并当风干水渍周期计时器 T3的计时时间大于等于风干水 渍周期预设值 TK4时, 控制器 251控制主电机 270关闭。 其中, 在本发明的一个实施 例中, 风干水渍周期预设值 TK4可以为 3分钟〜 10分钟。 优选地, 风干水渍周期预设 值 TK4为 3分钟。
也就是说, 在风干吸油烟机时, 在风干水渍周期计时器 T3的值即计时时间小于等 于风干水渍周期预设值 TK4的期间内开启主电机 270抽风, 加快吸油烟机内部的空气 流动, 使吸油烟机内部的水渍得到快速风干。
在本发明的实施例中, 控制器 251控制加热器 230开启进行预热, 并在加热器 230 预热后控制水泵 220 开启以对吸油烟机进行热清洗, 以及在吸油烟机热清洗完成之后 控制加热器 230以烘干加热器 230的内部水渍和控制主电机 270以风干吸油烟机的内 部水渍, 从而完成整个清洗过程。
下面结合图 6和图 7对本发明实施例提出的吸油烟机的清洗装置 200的控制电路 250进行描述。 其中, CN1与水泵 220电连接, CN2与主电机 270电连接, J1和 J4与 加热器 230例如为蒸汽发生器电连接, CN3与温度传感器 260电连接, J2和 J3连接市 电。

也就是说, 当加热器例如为蒸汽发生器的温度大于超限预设温度值 KP时, 控制水 泵、加热器和主电机关闭; 当加热器的温度小于等于超限预设温度值 KP且大于水泵开 启温度预设值 KN时, 控制水泵开启, 其中, KN< KP; 当加热器的温度小于水泵关闭 温度预设值 KF时, 控制水泵关闭, 其中, KF< KN。 其中, 在本发明的一个实施例中, 超限预设温度值 KP 可以为 140 °C ~180°C, 水泵开启温度预设值 KN 可以为 110 °C ~120°C, 水泵关闭温度预设值 KF可以为 100°C ~110°C。
步骤 S209, 判断主电机点动周期计时器 T2的值是否小于点动有效预设值 TK2例 如为 1秒, 若是进入步骤 S210, 若否进入步骤 S211。
步骤 S210, 开启主电机, 进入步骤 S212。
步骤 S211 , 关闭主电机, 进入步骤 S212。
也就是说, 在对吸油烟机进行热清洗时, 热清洗周期计时器 T1和主电机点动周期 计时器 T2开始计时, 其中, 当主电机点动周期计时器 T2的计时时间小于点动有效预 设值 TK2时, 控制主电机开启; 当主电机点动周期计时器 T2的计时时间大于等于点 动有效预设值 TK2时, 控制主电机关闭。 其中, 在本发明的一个实施例中, 点动有效 预设值 TK2可以为 0.5秒〜 2秒。
步骤 S212, 判断主电机点动周期计时器 T2 的值即计时时间是否大于等于点动周 期预设值 TK3例如为 12秒, 若是进入步骤 S213 , 若否进入步骤 S214。
步骤 S213, 清零主电机点动周期计时器 T2, 开启主电机点动周期计时器 Τ2重新 计时, 进入步骤 S214。
步骤 S214, 判断热清洗周期计时器 T1 的值即计时时间是否大于清洗时间预设值 TK1例如为 12分钟, 若是进入步骤 S215, 若否返回步骤 S202。
步骤 S215, 关闭蒸汽发生器, 关闭水泵, 关闭主电机, 进入下一步。
在本发明的实施例中, 当主电机点动周期计时器 T2的计时时间大于等于点动周期 预设值 TK3时, 清零主电机点动周期计时器 T2, 主电机点动周期计时器 Τ2重新开始 计时, 其中, ΤΚ2<ΤΚ3; 当热清洗周期计时器 T1的计时时间大于等于清洗时间预设 值 TK1 时, 控制水泵、 加热器和主电机关闭, 其中, ΤΚ3<ΤΚ1。 其中, 在本发明的 一个实施例中, 清洗时间预设值 TK1可以为 6分钟〜 20分钟, 点动有效预设值 ΤΚ2可 以为 0.5秒〜 2秒, 且 10 ΤΚ1/ΤΚ3 70, 即 10 (清洗时间预设值 TK1/点动周期预设 值 ΤΚ3 ) 70。在本实施例中, 清洗时间预设值 TK1为 12分钟, 点动有效预设值 ΤΚ2 为 1秒, 点动周期预设值 ΤΚ3为 12秒,其中, ΤΚ1/ΤΚ3=60,符合点动周期预设值 ΤΚ3 的取值范围满足条件: 10 (清洗时间预设值 TK1/点动周期预设值 ΤΚ3 ) 70。
需要说明的是, 在步骤 S2中, 在对吸油烟机进行热清洗时, 缺水、 管路堵塞等异 常会造成加热器例如蒸汽发生器的温度过高, 而加热器例如蒸汽发生器的温度过高有 可能造成清洗装置的损坏或产生危及人身财产安全的危险, 因此判断加热器例如蒸汽 发生器的温度是否大于超限温度预设值 KP, 如果否则继续热清洗, 如果是则关闭判断 蒸汽发生器提前结束步骤 S2热清洗进入步骤 S4风干吸油烟机内部水渍。 为保证热清 洗效果, 根据判断加热器例如蒸汽发生器的温度来确定水泵是否抽水, 当加热器例如 蒸汽发生器的温度低于水泵关闭温度预设值 KF时关闭水泵停止抽水,可防止此热清洗 中冷水喷出而影响热清洗效果, 水泵停止抽水后, 当蒸汽发生器的温度达到水泵开启 温度预设值 ΚΝ 时才恢复开启水泵抽水, 这样能使水在蒸汽发生器内部充分气化, 以 保证热清洗效果。 为使安装在主电机上的叶轮的各个部位能够得到有效清洗, 根据判 断控制器的主电机点动周期计时器 Τ2的值是否小于点动有效预设值 ΤΚ2来确定是否 启动主电机, 本实施例的点动周期预设值 ΤΚ3=12秒, 在每个点动周期的 1秒前即当 主电机点动周期计时器 Τ2的值小于点动有效预设值 ΤΚ2时启动主电机, 1秒后, 即当 主电机点动周期计时器 Τ2的值大于等于点动有效预设值 ΤΚ2后关闭主电机, 当主电 机点动周期计时器 Τ2的值大于等于点动周期预设值 ΤΚ3, 主电机点动周期计时器 Τ2 清零, 然后重新计时开始新一个点动周期计时, 通过这样实现在每次热清洗期间主电 机多次短时间歇启动, 电机的短时间歇启动带动叶轮位置的改变, 使叶轮的各个部位 能够得到有效清洗。 为方便描述, 电机的短时间歇启动下面简称为点动, 点动周期预 设值 ΤΚ3的取值范围满足条件:10 (清洗时间预设值 TK1/点动周期预设值 ΤΚ3) 70, 因为, 点动次数过多会造成叶轮持续旋转吸走部分蒸汽而使热清洗效果变差, 点动次 数过少会造成叶轮部分位置的不到清洗。
在本发明的实施例中, 在步骤 S2完成后, 即对吸油烟机进行热清洗完成之后, 加 热器例如蒸汽发生器内仍残留水渍, 而加热器例如蒸汽发生器一般为金属材质, 如果 不对蒸汽发生器内残留的水渍进行烘干, 时间长后残留的水渍、 空气、 蒸汽发生器的 共同作用会使蒸汽发生器产生氧化损坏, 因此需要烘干蒸汽发生器内部水渍, 进入步 骤 S3。
S3, 控制加热器以烘干加热器的内部水渍。
具体地, 在本发明的一个实施例中, 在步骤 S3中, 如图 11所示, 上述的吸油烟 机的清洗装置的控制方法还包括:
步骤 S301 ,进行一次加热器例如蒸汽发生器温度值采样以获得蒸汽发生器的温度, 进入步骤 S302。

步骤 S303, 开启蒸汽发生器, 返回步骤 S301。
步骤 S304, 关闭蒸汽发生器, 进入下一步。
也就是说, 在烘干加热器例如蒸汽发生器时, 当加热器的温度大于烘干温度预设 值 KD 时, 控制加热器关闭。 其中, 在本发明的一个实施例中, 烘干温度预设值 KD 可以为 130°C ~150°C。 优选地, 烘干温度预设值 KD为 150°C。
在本发明的实施例中, 在烘干加热器例如蒸汽发生器内部水渍中, 通过判断蒸汽 发生器的温度是否大于烘干温度预设值 KD 来确定是否开启蒸汽发生器, 直到蒸汽发 生器的温度大于烘干温度预设值 KD 才关闭蒸汽发生器, 本实施例中的烘干温度预设 值 KD为 150°C远高于水的沸腾温度 100°C, 能有效保证蒸汽发生器内仍残留水渍得到 烘干。
S4, 控制吸油烟机中的主电机以风干吸油烟机的内部水渍。
具体地, 在本发明的一个实施例中, 在步骤 S4中, 如图 12所示, 上述的吸油烟 机的清洗装置的控制方法还包括:
步骤 S401 , 启动风干水渍周期计时器 T3计时, 开启主电机, 进入步骤 S402。 步骤 S402, 判断风干水渍周期计时器 T3 的值即计时时间是否大于等于风干水渍 周期预设值 TK4, 若否进入步骤 S403, 若是进入步骤 S404。
步骤 S403, 开启主电机, 返回步骤 S403。
步骤 S404, 关闭主电机, 结束。
也就是说, 在风干吸油烟机时, 控制器中的风干水渍周期计时器 T3开始计时, 并 当风干水渍周期计时器 T3 的计时时间大于等于风干水渍周期预设值 TK4时, 控制主 电机关闭。 其中, 在本发明的一个实施例中, 风干水渍周期预设值 TK4可以为 3分钟 ~10分钟。 优选地, 风干水渍周期预设值 TK4为 3分钟。
在本发明的实施例中, 在步骤 S2完成后即对吸油烟机进行热清洗时完成之后, 蒸 汽会在清洗叶轮、 滤网等金属部件冷凝形成水渍, 而水渍的存在一方面滋生细菌, 另 一方面叶轮、 滤网等金属部件在水渍与空气的共同作用下会氧化生锈, 因此需要风干 吸油烟机内部水渍。 在步骤 S4中即风干吸油烟机时, 在风干水渍周期计时器 T3的值 即计时时间小于等于风干水渍周期预设值 TK4的期间内开启主电机抽风, 加快吸油烟 机内部的空气流动, 使吸油烟机内部的水渍得到快速风干, 从而完成包括预热、 热清 洗、 烘干、 风干 4个步骤的整个清洗过程。
需要说明的是, 本发明是以高温蒸汽清洗油污, 由于蒸汽比冷水的温度高, 能快 速软化、 溶解油污, 因而能使吸油烟机的清洗效果更加彻底, 用水量与冷水清洗相比 也用量较少, 清洗所用时间为预热、 热清洗、 烘干、 风干 4个步骤所需时间的累加, 相比人手冷水清洗所用的时间要短, 所以更加快捷。
综上所述, 根据本发明实施例提出的吸油烟机、 吸油烟机的清洗装置及其控制方 法, 通过加热器例如蒸汽发生器产生的水蒸气和 /或热水清洗吸油烟机的油污, 不仅能 够彻底清除油污, 还环保、 节水。 同时整个清洗过程自动完成, 无需人手拆装, 使用 起来更加方便, 给人们的生活带来了方便, 提高了用户的使用效果。 另外, 本发明清 洗吸油烟机时无须使用清洁剂, 因而更加环保。
