技术领域
本公开涉及吸油烟机技术领域，更具体地，涉及吸油烟机、用于吸油烟机的清洗系统和用于吸油烟机的清洗系统。
背景技术
吸油烟机广泛应用于现代厨房中。一些相关技术中的吸油烟机通过离心式风机抽吸并外排了烹饪过程中产生的绝大部分油烟，以维护厨房环境的干净、清爽。但是，在吸油烟机的工作过程中，不可避免地被油烟凝结、污染了吸油烟机内的大部分结构元件，例如叶轮、蜗壳、风道等。烟机在使用过程中，油污在流道及烟机的外部吸附，烟机的风阻提高，会影响烟机性能，且烟机外部油污直接影响用户在烹饪过程中使用产品的体验和烹饪状态。
为此，一些相关技术中针对性地设计了各种内部清洗系统，例如采用热化油、蒸汽、热水及冷水等各种方式，有效清洗机内元器件，减小吸油烟机的内部风阻，使吸油烟机能够保持较好的工作性能。但是，这些吸油烟机却不能对烟机的外部，如烟机的外表面、灶台等部位进行清洗。
由于吸油烟机晚开机或油烟抽吸功能变差等种种原因，烹饪过程中总会有部分油烟未被完全吸收并通过烟机排出，这小部分的油烟将留存并久而久之不断污染灶台、机壳外壁等。目前，烟机的外部清洗主要使用人工或者另外购买的蒸汽清洗机等进行清洗，人工清洗无法彻底去污，需要用户不时的手动擦拭清洗灶台等油污量大的地方，给用户造成诸多不便、操作繁琐，而且可选择的清洗工具不多，选择困难。而另外购买蒸汽清洗机则造成了经济浪费。此外，相关技术中的吸油烟机没有能够对外部进行清洗的结构，或者外部清洗结构繁琐，使用不便，有待于进一步改进。

具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制，本领域的普通技术人员在不脱离本公开的原理和宗旨的情况下可以对这些实施例进行多种变化、修改、替换和变型，本公开的范围由权利要求及其等同物限定。
在本公开的描述中，需要理解的是，术语“上”、“下”、“前”、“后”、“左”、“右”、“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本公开和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本公开的限制。此外，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本公开的描述中，除非另有说明，“多个”的含义是两个或两个以上。
下面参考图1-图10描述根据本公开一些实施例的用于吸油烟机的清洗系统100。
参照图1-图3所示，根据本公开实施例的用于吸油烟机的清洗系统100可以包括：清 洗介质供给组件10、内部清洗支路20和外部清洗支路30。
具体而言，清洗介质供给组件10可以提供清洗介质，并且清洗介质供给组件10具有可以输出清洗介质的出介质口101。内部清洗支路20的进口和外部清洗支路30的进口均可以与出介质口101连通。
由此，不同于相关技术中，烟机仅具有内部清洗功能，根据本公开实施例的清洗系统100可以形成为外延式清洗系统，清洗介质供给组件10提供的清洗介质既可以通过内部清洗支路20对吸油烟机的内部进行清洗，降低吸油烟机的风阻，提高吸油烟机的性能，又可以通过外部清洗支路30对吸油烟机的外部进行清洗，达到去污杀菌的效果，保证厨房的整洁，提高用户的烹饪体验。清洗系统100可以对吸附在吸油烟机的内部和外部的油污、灰尘等脏物进行彻底清洗，而且用户无需另外购买用于外部清洁的清洗设备或者手动清洗，可以利用吸油烟机的内部的清洗介质供给组件10将产生的清洗介质导出到外部进行清洗，避免了经济浪费，也更加省力。
这里，“内部”可以理解为吸油烟机的机壳内的需要进行清洗的部位，例如，可以是吸油烟机的叶轮、蜗壳、流道等；“外部”可以理解为吸油烟机的机壳外的需要进行清洗的部位，例如，可以是吸油烟机的机壳的外表面或者灶台等。
此外，在本公开中，外部清洗支路30上可以设有外部清洗组件31，并且外部清洗组件31可以拆卸。在外部清洗组件31装入时，内部清洗支路20可以断开，外部清洗支路30可以导通，此时，可以对吸油烟机的外部进行清洗。在外部清洗组件31拆下时，外部清洗支路30可以断开，内部清洗支路20可以导通，此时，可以对吸油烟机的内部进行清洗。也就是说，在需要对吸油烟机的外部进行清洗时，可以将外部清洗组件31装入，不需要对吸油烟机的外部进行清洗时，可以将外部清洗组件31拆下另外存放，可以减小吸油烟机的占用空间，吸油烟机的外观更加整洁美观，避免妨碍吸油烟机的正常使用，也可以防止外部清洗组件31损坏。
需要说明的是，内部清洗支路20的导通和断开的状态切换可以通过多种方式实现。
例如，在本公开的一些实施例中，内部清洗支路20可以在外部清洗组件31的拆装动作的触发下实现状态切换，当外部清洗组件31装入时，可以触发内部清洗支路20切换至断开状态，当外部清洗组件31拆下时，可以触发内部清洗支路20切换至导通状态。
再例如，在本公开的另一些实施例中，内部清洗支路20可以根据压力值的高低实现状态切换，内部清洗支路20的压力达到预定值时，内部清洗支路20可以导通，否则内部清洗支路20断开。
当然，内部清洗支路20还可以在外部清洗组件31的拆装动作和内部清洗支路20的压力的配合作用下发生状态切换，换言之，内部清洗支路20可以在外部清洗组件31的拆装 动作和内部清洗支路20的压力中的至少一个的触发下发生状态切换。
根据本公开实施例的用于吸油烟机的清洗系统100具有内部清洗系统20和外部清洗系统30，可以对吸油烟机的内部和外部进行清洗，使用更加经济省力，外观更加整洁美观，并且内部清洗系统20的状态切换可以通过多种方式实现，操作更加简单方便，可以满足更多的使用需求。
需要理解的是，在本公开的描述中，“内部清洗支路20导通”通常理解为由清洗介质供给组件10的出介质口101和内部清洗支路20的出口之间的部分处于连通状态或通路状态，此时清洗介质可以从出介质口101流至内部清洗支路20的出口处；“内部清洗支路20断开”通常理解为由清洗介质供给组件10的出介质口101和内部清洗支路20的出口之间的部分处于断开状态或断路状态，此时清洗介质从出介质口101流出后将不能顺利地流至内部清洗支路20的出口处。
“外部清洗支路30导通”和“外部清洗支路30断开”也作类似理解，即：“外部清洗支路30导通”可以理解为由清洗介质供给组件10的出介质口101和外部清洗支路30的出口之间的部分处于连通状态或通路状态，此时清洗介质可以从出介质口101流至外部清洗支路30的出口处，此时，当外部清洗组件31装入外部清洗支路30时，清洗介质可以进一步流至外部清洗组件31，其中，在下文所公开的外部清洗支路30设有支路接头部32的一些实施例中，在外部清洗组件31未装入时，清洗介质可以流至支路接头部31处，当外部清洗组件31装入时，清洗介质可以经过支路接头部31和外接头部312流至外部清洗组件31；“外部清洗支路30断开”可以理解为由清洗介质供给组件10的出介质口101和外部清洗支路30的出口之间的部分处于断开状态或断路状态，此时清洗介质从出介质口101流出后将不能流至外部清洗支路30的出口处。
在外部清洗组件31的拆装动作可以触发内部清洗支路20状态切换的实施例中，如图1和图3所示，在外部清洗组件31装入时，外部清洗支路30可以立即导通，在外部清洗组件31拆下时，外部清洗支路30可以立即断开，外部清洗支路30的导通和断开控制灵敏，且可以有效防止外部清洗组件31拆下时发生清洗介质泄漏及伤害事故的发生，更加安全。
而在外部清洗组件31拆装时，内部清洗支路20的状态切换可以立即发生，也可以延迟发生。例如，在如图1所示的具体实施例中，内部清洗支路20的状态切换仅通过外部清洗组件31的拆装动作触发，在外部清洗组件31装入时，内部清洗支路20可以立即断开，在外部清洗组件31拆下时，内部清洗支路20可以立即导通。
再例如，在如图3所示的实施例中，外部清洗组件31的拆装动作和内部清洗支路20的压力配合作用触发内部清洗支路20的状态切换。外部清洗组件31拆装时，内部清洗支路20的压力可以逐渐变化以实现内部清洗支路20的状态的延迟切换，或者内部清洗支路 20的压力可以瞬间变化以实现内部清洗支路20的立即切换。
另外，如图2所示，在内部清洗支路20的压力控制内部清洗支路20的状态切换的实施例中，内部清洗支路20上可以设有压力阀21。在内部清洗支路20的压力达到第一预定压力时，压力阀21打开可以导通内部清洗支路20，在内部清洗支路20的压力低于第一预定压力时，压力阀21关闭可以断开内部清洗支路20。内部清洗支路20的导通和断开状态的切换更加灵敏。
进一步地，压力阀21可以为单向阀，结构更简单，易于安装，并且可以防止清洗介质回流，更加安全可靠。
根据本公开进一步的实施例，如图1、图4-图8所示，外部清洗支路30可以具有支路接头部32，外部清洗组件31可以包括：外清洗部311和外接头部312。
其中，外清洗部311可以用于出清洗介质，用户可以控制外清洗部311对吸油烟机的外部进行清洗，操作方便省力。在本公开的一些示例中，外清洗部311可以为喷枪或者喷头等，并且外清洗部311可以具有开关组件，开关组件打开时，外清洗部311导通，可以喷出清洗介质，开关组件关闭时，外清洗部311关闭。用户在使用过程中可以更方便的控制外清洗部311的通断，而无需频繁拆装外部清洗组件31或者调控内部清洗支路20的压力以控制外部清洗支路30的通断状态，实用性更强。
此外，如图1、图4和图6所示，外接头部312与外清洗部311相连，并且外接头部312可以与支路接头部32可拆卸地相连。当外接头部312与支路接头部32相连时，如图4所示，支路接头部32的出口与外接头部312的进口可以连通，清洗介质可以由支路接头部32的出口进入外接头部312的进口，进而经过外接头部312进入外清洗部311。外接头部312与支路接头部32分离时，如图6所示，支路接头部32的出口关闭，清洗介质无法由支路接头部32的出口流出。
在本公开的一些实施例中，如图1、图3和图9所示，内部清洗支路20、外部清洗支路30与清洗介质供给组件10可以通过两位三通的控制阀40实现两两连通。具体地，控制阀40可以包括三个通道，其中通道P可以与清洗介质供给组件10的出介质口101密封连通，通道A可以与内部清洗支路20密封连通，通道B可以与外部清洗支路30密封连通。并且控制阀40可以包括内导通位和外导通位，在外部清洗组件31装入时，控制阀40可以处于外导通位，此时，通道P与通道B导通，使外部清洗支路30导通，清洗介质供给组件10与外部清洗支路30连通；在外部清洗组件31拆下时，控制阀40可以处于内导通位，此时，通道P与通道A导通，使内部清洗支路20导通，清洗介质供给组件10与内部清洗支路20连通。
进一步地，如图4-图6所示，外部清洗支路30上可以设有微动开关33，在外部清洗 组件31装入时，微动开关33可以被触发以控制控制阀40处于外导通位，并且在外部清洗组件31拆下时，微动开关33可以被触发以控制控制阀40处于内导通位。由此，通过外部清洗组件31的拆装可以触发内部清洗支路20的状态切换，清洗介质供给组件10与内部清洗支路20连通或者清洗介质供给组件10与外部清洗支路30连通的转换只需通过外部清洗组件31拆装的一步操作即可实现，操作更加简单方便。
继续参照图4-图6所示，在具有支路接头部32、外清洗部311和外接头部312的实施例中，微动开关33可以设在支路接头部32上。在外接头部312与支路接头部32相连时，外接头部312可以止抵微动开关33的触点331，以触发微动开关33使控制阀40处于外导通位，外接头部312与支路接头部32分离时，外接头部312可以释放微动开关33的触点331，以触发微动开关33使控制阀40位于内导通位，微动开关33的位置设置合理。
此外，微动开关33可以与支路接头部32可拆卸的相连，也就是说，在需要微动开关33控制内部清洗支路20导通状态的实施例中，如图4所示，可以装入微动开关33，在不需要微动开关33控制内部清洗支路20导通状态的实施例中，如图10所示，可以拆下微动开关33。
根据本公开的一些实施例，如图4-图5所示，支路接头部32的出口处可以设有阀芯组件34，并且阀芯组件34可以在打开位置和关闭位置之间移动。外接头部312与支路接头部32的连接过程中，外接头部312可以止抵阀芯组件34，使阀芯组件34向打开支路接头部32的出口的打开位置移动，当外接头部312与支路接头部32相连时，如图4和图5所示，支路接头部32的出口完全打开。在外接头部312与支路接头部32分离时，阀芯组件34不受外接头部312的止抵，阀芯组件34可以复位至关闭支路接头部32的出口的关闭位置。
进一步地，如图4-图6所示，阀芯组件34可以包括：阀芯341和第一弹性件342。阀芯341的一端可以与外接头部312止抵，使阀芯组件34可以在外接头部312的止抵下移动。阀芯341的另一端可以设有封口部343，阀芯341上还可以设有流体通道。封口部343可以用于封闭支路接头部32的出口，流体通道可以在阀芯组件34处于打开位置时连通支路接头部32的出口与外接头部312的进口。
此外，第一弹性件342可以止抵于支路接头部32和阀芯341之间。如图5所示，阀芯341在外接头部312的止抵作用下移动至打开位置，第一弹性件342处于压缩状态，流体通道连通支路接头部32的出口与外接头部312的进口。如图6所示，当外接头部312拆下时，阀芯341失去止抵作用，第一弹性件342恢复原状，阀芯341可以在第一弹性件342的止抵下自动复位至关闭位置，防止清洗介质由支路接头部32的出口泄漏而发生伤害事故，更加安全可靠。
进一步地，在如图5所示的具体实施例中，阀芯341可以大体形成为沿清洗介质的流动方向延伸的柱体，封口部343可以大体形成为沿垂直于清洗介质的流动方向的平面延伸的圆形，阀芯341的邻近外接头部312的一端的至少一部分形成有流体通道。
另外，阀芯341的邻近外接头部312的一端的至少一部分由多个板体构成，多个板体由阀芯341的轴线沿阀芯341的径向向外延伸，并且多个板体的远离阀芯341的轴线的一端沿阀芯341的周向间隔开设置，相邻两个板体之间限定出流体通道。由此，可以保证在阀芯341与外接头部312止抵时，清洗介质可以通过流体通道由支路接头部32进入外接头部312。需要说明的是，图5所示阀芯341结构为剖视图，剖线经过板体，因此，在图5中未示出流体通道结构。
再进一步地，第一弹性件342可以为外套在阀芯341上的螺旋弹簧，结构简单并且可以循环使用，不易老化变形。封口部343可以为套设在阀芯341上的密封圈，密封圈的密封效果更好，在外接头部342拆下时，可以有效密封支路接头部32的出口，防止清洗介质泄漏，更加安全。
根据本公开进一步的实施例，如图5和图6所示，支路接头部32可以包括支路外接管322、支路内接管323和密封圈324，支路外接管322和支路内接管323可以通过螺纹连接，并且支路外接管322和支路内接管323之间可以通过密封圈324密封，防止清洗介质泄漏。阀芯组件34的阀芯341可以穿设在支路内接管323内，阀芯组件34位于关闭位置时，阀芯组件34的封口部343可以止抵在支路内接管323的一端以封闭支路接头部32的出口。进行装配时，可以首先将阀芯组件34与支路内接管323进行组装，然后再将支路内接管323与支路外接管322进行组装，阀芯组件34安装更加方便，结构设计更加合理。
进一步地，密封圈324可以为硅胶圈，密封效果更好，并且更加耐磨，易于加工。
在本公开的一些实施例中，如图4-图7所示，支路接头部32上可以设有卡槽321，外接头部312可以包括：接头管313和卡勾314，接头管313的进口可以与外接头部312的出口连通，卡勾314可以与接头管313相连，并且卡勾314可以卡接在卡槽321内以实现外接头部312与支路接头部32的卡接，连接结构简单牢固。
此外，如图5所示，在具有微动开关33的实施例中，微动开关33的触点331可以伸入卡槽321，由此，当卡勾314卡接在卡槽321内时，卡勾314可以止抵触点331以触发微动开关33，实现通过外接头部312的拆装实现微动开关33的触发，结构设计更加合理。
进一步地，如图7所示，卡勾314可以包括：卡勾头3141和卡勾臂3142。其中，卡勾头3141可以卡接在卡槽321内，并且在具有微动开关33的实施例中，卡勾头3141可以与微动开关33的触点331止抵。卡勾臂3142的一端为自由端，卡勾臂3142的另一端为枢转端，并且自由端和枢转端之间可以形成有按压部3143。自由端可以相对于枢转端转动，以 使卡勾臂3142可以在按下位置和弹起位置之间相对于接头管313转动，卡勾头3141可以设在卡勾臂3142的自由端。
由此，需要将外接头部312卡接入支路接头部32时，可以按压按压部3143使卡勾臂3142移动至按下位置，此时，卡勾头3141向内移动，即向远离卡槽321的方向移动，此时卡勾头3141可以向卡槽321内安装。待卡勾头3141移动至位置与卡槽321相对应后，停止按压按压部3143，卡勾头3141向外移动，即向插入卡槽321的方向移动，卡勾臂3142移动至弹起位置，卡勾头3141卡接在卡槽321内，外接头部312与支路接头部32安装完成。
进一步地，如图4和图7所示，外接头部312还可以包括第二弹性件315，第二弹性件315可以止抵在按压部3143与接头管313之间。卡勾臂3142位于按下位置时，第二弹性件315处于压缩状态，当停止按压按压部3143后，第二弹性件315恢复原状，同时第二弹性件315可以止抵按压部3143并推动按压部3143自动复位，使卡勾头3141卡入卡槽321。只需通过按压或者停止按压按压部3143即可完成外接头部312与支路接头部32的卡接，操作过程简单。
在本公开的一些实施例中，第二弹性件315可以为螺旋弹簧，结构简单且可以循环使用，不易老化变形。
另外，如图7所示，按压部3143上可以设有安装凸起3144，接头管313的外侧面上可以设有止抵槽3131。安装凸起3144由按压部3143的内表面朝向接头管313的方向凸出，螺旋弹簧的一端可以套设在安装凸起3144上，并且螺旋弹簧的另一端可以止抵在止抵槽3131内，安装凸起3144与止抵槽3131配合可以限制螺旋弹簧相对于按压部3143和接头管313的位置，防止螺旋弹簧的位置发生偏移而无法推动按压部3143复位。
根据本公开的一些实施例，如图7和图8所示，外接头部312还可以包括外壳316，接头管313可以伸入外壳316内，外壳316可以对接头管313进行保护，防止接头管313意外损坏，外接头部312的外观也更加整洁美观。
另外，外壳316上可以设有操作孔3161，按压部3143可以由操作孔3161露出，使用户可以由外壳316的外侧对按压部3143进行按压或者停止按压，操作更加方便。接头管313的两侧可以设有限位槽3132，外壳316的两侧壁面上可以设有限位凸起3162，限位凸起3162可以插接在限位槽3132内，由此实现接头管313与外壳316的连接。
需要说明的是，本公开对限位槽3132和限位凸起3162的形状不做特殊限制，只需要满足限位槽3132与限位凸起3162配合以实现接头管313与外壳316的连接的要求即可。例如，在本公开的一些具体实施例中，限位槽3132可以为方形孔槽，限位凸起3162可以为方形凸起，方形凸起可以插入方形孔槽内实现接头管313与外壳316的连接。
在本公开中，卡勾314可以包括多个，多个卡勾314可以沿接头管313的周向分布，每个按压部3143的枢转端可以具有轴杆3145，外壳316上可以具有与轴杆3145位置相对应的轴孔3163，轴杆3145可以插设在轴孔3163内以实现卡勾314与接头管313的连接，并且轴杆3145在轴孔3163内转动使自由端可以相对于枢转端转动。
例如，在如图7所示的具体实施例中，卡勾314包括两个，两个卡勾314分别设在接头管313的两侧，用户可以由两侧的按压部3143进行操作，操作更加方便，并且卡勾314由两侧进行卡接，可以保证卡接牢固。
当然，在本公开中，卡勾314的数量不限于两个，卡勾314的数量可以根据实际情况需要灵活设置，只需要满足卡勾314卡接在卡槽321内以实现外接头部312与支路接头部32连接的要求即可。例如，在本公开的另一些实施例中，卡勾314的数量也可以为三个、四个或者更多个。需要说明的是，在卡勾314为多个的实施例中，第二弹性件315、安装凸起3144和止抵槽3131的数量可以与卡勾314相同并且一一对应的设置。
根据本公开进一步的实施例，如图7所示，外接头部312可以包括：内套管317和外套管318。
内套管317的一端可以伸入外壳316的远离支路接头部32的一端，外清洗部311可以伸入内套管317内与外接头部312连接，例如，外清洗部311可以与接头管313的远离支路接头部32的一端相连。由此，内套管317可以对外清洗部311与接头管313的连接处进行保护，防止发生松脱而导致清洗介质泄漏或者伤害事故的发生。
外套管318可以外套在内套管317外，内套管317与外套管318大体形成轴孔配合，一方面可以对外清洗部311与接头管313的连接处进一步保护，另一方面，外套管318可以形成为装饰管，使外接头部312的外观更加美观。
另外，本公开对内套管317、外套管318的连接固定结构不做特殊限制，例如，在如图7所示的具体实施例中，内套管317的外周面上可以设有外环形凹槽3171，外壳316的内周壁上可以设有内环形凸起3164，内环形凸起3164可以插设在外环形凹槽3171内，内环形凸起3164与外环形凹槽3171配合可以使内套管317与外壳316的位置相对固定。
外套管318的一端可以设有外弯折边3181，外壳316的端部可以设有内翻边3165，外弯折边3181可以止挡在内翻边3165与内环形凸起3164之间，以使外套管318与外壳316的位置相对固定。内套管317和外套管318分别相对于外壳316的径向和轴向位置固定且固定结构简单牢固，但内套管317和外套管318分别相对于外壳316的周向可以自由旋转，使用过程更加方便。
进一步地，外壳316可以包括第一壳体和第二壳体，第一壳体和第二壳体可以卡接相连或者通过螺纹紧固件319连接固定构成外壳316，接头管313、卡勾314、内套管317和 外套管318可以位于第一壳体和第二壳体之间所限定出的安装空间内。在装配过程中，可以先将内套管317与外套管318进行装配，然后将接头管313、卡勾314、内套管317和外套管318安装于第一壳体内，最后将第二壳体与第一壳体连接并通过卡接结构或者螺纹紧固件319进行固定，使外接头部312的装配更加简单，易于操作。
此外，第一壳体和第二壳体的彼此相对的面上可以分别设有定位槽和定位凸起，定位槽与定位凸起配合可以初步定位第一壳体和第二壳体，然后再通过卡接结构或者螺纹紧固件319等结构进行固定，使装配过程更加简单。
根据本公开的一些实施例的清洗系统100还可以包括压力开关组件50，如图1所示，压力开关组件50可以与控制阀40相连，压力开关组件50可以对控制阀40与出介质口101之间的压力进行检测，当压力开关组件50检测到控制阀40与出介质口101之间的压力达到第二预定压力时，压力开关组件50可以控制控制阀40处于内导通位，即控制内部清洗支路20导通，外部清洗支路30断开。
由此，在外部清洗组件31装入时，如果外部清洗支路30通过其他装置控制或者发生堵塞使清洗介质长时间无法由外部清洗支路30排出时，压力开关组件50可以使内部清洗支路20导通，以降低清洗系统100内的压力，防止清洗系统100内的压力过大而导致伤害事故的发生。
在本公开的一些实施例中，如图3所示，清洗系统100还可以包括：泄压支路60和第一泄压阀61。具体地，泄压支路60的一端可以与出介质口101连通，泄压支路60的另一端可以连接在控制阀40与内部清洗支路20的用于出清洗介质的内清洗部22之间，这里内清洗部22可以为喷管或者喷头等结构。第一泄压阀61可以设在泄压支路60上，第一泄压阀61可以处于常闭状态，并且在出介质口101与控制阀40之间的压力达到第三预定压力时，第一泄压阀61可以打开以导通泄压支路60。
由此，在外部清洗组件31装入时，如果外部清洗支路30通过其他装置控制或者发生堵塞使清洗介质长时间无法由外部清洗支路30排出时，可以通过泄压支路60的第一泄压阀61控制使清洗介质由内清洗部22排出从而使清洗系统100内的压力降低，防止清洗系统100内的压力过大而导致伤害事故的发生。
进一步地，第一泄压阀61可以为单向阀，结构简单，易于安装，并且可以防止清洗介质回流，更加安全可靠。
需要说明的是，在本公开中，第一预定压力、第二预定压力和第三预定压力的压力值可以根据实际情况需要灵活设置，第一预定压力、第二预定压力和第三预定压力的压力值可以相同也可以不同，这都在本公开的保护范围之内。
根据本公开的一些实施例，如图1-图3所示，清洗介质供给组件10可以包括：储液装 置11、蒸汽发生器12和驱动装置13。其中，蒸汽发生器12可以与储液装置11连通，驱动装置13可以设在储液装置11与蒸汽发生器12之间。驱动装置13可以驱动储液装置11内的液体流入蒸汽发生器12内，并且蒸汽发生器12内可以设有加热件，加热件可以将液体加热形成蒸汽，蒸汽发生器12的出蒸汽口为出介质口101，蒸汽可以由出介质口101流出以作为清洗介质对吸油烟机的内部或者外部进行清洗。
在本公开中，储液装置11可以为水杯，驱动装置13可以为水泵，水杯内可以储存有常温的清水或者清洁剂等液体，液体在水泵的驱动下可以进入蒸汽发生器12内加热为蒸汽状态的清洗介质并由出介质口101流出。
进一步地，继续参照图1-图3所示，清洗介质供给组件10还可以包括第二泄压阀14，第二泄压阀14的设置位置不做特殊限制，例如，第二泄压阀14可以设在蒸汽发生器12与储液装置11之间，或者可以设在蒸汽发生器12与驱动装置13之间。第二泄压阀14处于常闭状态，并且在清洗介质供给组件10的压力达到第四预定压力时，第二泄压阀14可以打开以降低清洗介质供给组件10的压力，防止清洗介质供给组件10的压力过大而导致伤害事故的发生。
需要说明的是，第四预定压力的数值可以根据实际情况需要灵活设置。例如，在如图2所示的包括压力阀21的示例中，第四预定压力的压力值可以大于第一预定压力的压力值，由此，在不发生故障的情况下，压力阀21可以先于第二泄压阀14打开以降低清洗系统100内的压力，避免清洗介质的浪费。
再例如，在如图1所示的包括压力开关组件50的示例中，第四预定压力的压力值可以等于第二预定压力的压力值，由此，当控制阀40与出介质口101之间的压力达到第二预定压力时，第二泄压阀14打开进行泄压，同时压力开关组件50控制控制阀40处于内导通位。当然，第四预定压力的压力值也可以大于第二预定压力的压力值，使在不发生故障的情况下，压力开关组件50先于第二泄压阀14动作，避免清洗介质的浪费。
又例如，在如图3所示的包括泄压支路60和第一泄压阀61的示例中，第四预定压力的压力值可以大于第三预定压力的压力值，由此，在不发生故障的情况下，第一泄压阀61可以先于第二泄压阀14打开以降低清洗系统100内的压力，避免清洗介质的浪费。
在本公开的一些实施例中，清洗系统100还可以包括收集装置24，收集装置24可以设置于内部待清洗件23的下方。当清洗系统100对吸油烟机的内部进行清洗时，清洗介质由内清洗部22喷出，一部分进入大气，另一部分喷到内部待清洗件23的表面并对内部待清洗件23表面的油污等脏物进行清洗，清洗介质在内部待清洗件23的表面冷凝，清洗下的脏物与冷凝液一起流入收集装置24。
可选地，在本公开中，收集装置24可以为油杯，用于收集冷凝液，收集装置24还可 以为分离过滤器，分离过滤器可以将冷凝液中的脏物进行分离，分离出的洁净的清洗介质的冷凝液可以再次进入清洗介质供给组件10以便循环利用，有利于节约资源。
下面参考附图详细描述根据本公开的具体实施例的清洗系统100，值得理解的是，下述描述只是示例性说明，而不能理解为对发明的限制。
实施例一：
如图1、图4-图9所示，清洗系统100包括储液装置11、蒸汽发生器12、驱动装置13、第二泄压阀14、内部清洗支路20、内清洗部22、收集装置24、外部清洗支路30、外清洗部311、外接头部312、支路接头部32、微动开关33、阀芯组件34、控制阀40和压力开关组件50。
外部清洗组件31未装入支路接头部32时，控制阀40处于内导通位，内部清洗支路20导通，外部清洗支路30关闭，驱动装置13驱动储液装置11的液体进入蒸汽发生器12并在蒸汽发生器12的加热件的加热下形成蒸汽状态的清洗介质，清洗介质由出介质口101流出并进入内部清洗支路20，清洗介质随后通过内清洗部22喷出，可以对吸油压机的内部进行清洗。喷出的清洗介质一部分进入大气，一部分在内部待清洗件23的表面冷凝后流入收集装置24，清洗下的油污等脏物随冷凝液进入收集装置24。
需要对吸油烟机的外部进行清洗时，首先将外部清洗组件31与支路接头部32进行装配。具体地，手动按压外部清洗组件31的外接头部312的按压部3143使第二弹性件315压缩，卡勾头3141向远离卡槽321的方向移动，控制外接头部312插入支路接头部32内，接头管313与阀芯341止抵，克服弹力使第一弹性件342压缩，阀芯组件34移动至打开位置，流体通道导通支路接头部32的出口和外接头部312的进口，此时，卡勾头3141移动至与卡槽321的位置相对应。停止按压按压部3143，卡勾头3141在第二弹性件315的弹性作用下复位并卡入卡槽321内，外接头部312与支路接头部32卡接形成单向阀组件，实现外部清洗组件31与支路接头部32的连接，外部清洗组件31与支路接头部32导通。
卡勾头3141卡入卡槽321的同时止抵微动开关33的触点331，触发微动开关33，微动开关33控制控制阀40通电处于外导通位，外部清洗支路30导通，内部清洗支路20关闭，清洗介质先后通过控制阀40、支路接头部32和外接头部312，进入外部清洗组件31的外清洗部311，按下外清洗部311的开关组件使外清洗部311打开，清洗介质可以由外清洗部311喷出，对吸油烟机的外部进行清洗。
当外清洗部311长时间处于非工作状态时，清洗介质供给组件10的压力以及出介质口101和控制阀40之间的压力增大，当压力达到第二预定压力时，第二泄压阀14进行泄压，同时压力开关组件50控制控制阀40位于内导通位，内部清洗支路20导通，外部清洗支路 30断开，使清洗介质进入内部清洗支路20对内部待清洗件23进行清洗，以降低清洗系统100内的压力。
当外部清洗组件31拆下时，阀芯组件34在第二弹性件315的弹力作用下复位，封口部343重新与支路内接管323的端部贴合，支路接头部32的出口自动关闭，可以防止清洗介质泄漏及伤害事故的发生。卡勾头3141触发微动开关33，微动开关33控制控制阀40断电处于内导通位，内部清洗支路20导通，外部清洗支路30关闭。
实施例二：
如图2、图9和图10所示，清洗系统100包括储液装置11、蒸汽发生器12、驱动装置13、第二泄压阀14、内部清洗支路20、压力阀21、内清洗部22、收集装置24、外部清洗支路30、外清洗部311、外接头部312、支路接头部32和阀芯组件34。
外部清洗组件31未装入支路接头部32时，内部清洗支路20和外部清洗支路30均关闭，驱动装置13驱动储液装置11的液体进入蒸汽发生器12并在蒸汽发生器12的加热件的加热下形成蒸汽状态的清洗介质，使内部清洗支路20和外部清洗支路30内的压力增大，当压力达到第一预定压力时，压力阀21打开，内部清洗支路20导通，外部清洗支路30关闭，清洗介质由出介质口101流出并进入内部清洗支路20，清洗介质随后通过内清洗部22喷出，可以对吸油压机的内部进行清洗。喷出的清洗介质一部分进入大气，一部分在内部待清洗件23的表面冷凝后流入收集装置24，清洗下的油污等脏物随冷凝液进入收集装置24。
需要对吸油烟机的外部进行清洗时，首先将外部清洗组件31与支路接头部32进行装配，装配过程与实施例1中所述过程相同，在此不再详述。
外部清洗组件31装入支路接头部32后，外部清洗支路30导通，打开外清洗部311的开关组件，清洗介质由外清洗部311喷出以用于吸油烟机的外部的清洗，使内部清洗支路20内的压力下降，压力值接近为零低于第二预定压力，压力阀21自动关闭，内部清洗支路20关闭。
当外清洗部311长时间处于非工作状态或者外部清洗组件31拆下时，内部清洗支路20的压力会升高，当再次高于第二预定压力时，压力阀21会再次打开，内部清洗支路20导通，清洗介质由内清洗部22喷出以对内部待清洗件23进行清洗。第二泄压阀14的第四预定压力的阀值压力大于压力阀21的第二预定压力，因此，在不发生故障的情况下，第二泄压阀14不会动作。
实施例三：
如图3、图4-图9所示，清洗系统100包括储液装置11、蒸汽发生器12、驱动装置13、第二泄压阀14、内部清洗支路20、内清洗部22、收集装置24、外部清洗支路30、外 清洗部311、外接头部312、支路接头部32、微动开关33、阀芯组件34、控制阀40、泄压支路60和第一泄压阀61。
外部清洗组件31未装入支路接头部32时，控制阀40处于内导通位，内部清洗支路20导通，外部清洗支路30关闭，泄压支路60关闭。驱动装置13驱动储液装置11的液体进入蒸汽发生器12并在蒸汽发生器12的加热件的加热下形成蒸汽状态的清洗介质，清洗介质由出介质口101流出并进入内部清洗支路20，清洗介质随后通过内清洗部22喷出，可以对吸油压机的内部进行清洗。喷出的清洗介质一部分进入大气，一部分在内部待清洗件23的表面冷凝后流入收集装置24，清洗下的油污等脏物随冷凝液进入收集装置24。
需要对吸油烟机的外部进行清洗时，首先将外部清洗组件31与支路接头部32进行装配，装配过程与实施例1中所述过程相同，在此不再详述。
外部清洗组件31与支路接头部32装配过程中，卡勾头3141卡入卡槽321的同时止抵微动开关33的触点331，触发微动开关33，微动开关33控制控制阀40通电处于外导通位，外部清洗支路30导通，内部清洗支路20关闭，泄压支路60关闭。清洗介质先后通过控制阀40、支路接头部32和外接头部312，进入外部清洗组件31的外清洗部311，按下外清洗部311的开关组件使外清洗部311打开，清洗介质可以由外清洗部311喷出，对吸油烟机的外部进行清洗。
当外清洗部311长时间处于非工作状态或者外部清洗组件31拆下时，泄压支路60的压力会升高，当压力高于第三预定压力时，第一泄压阀61打开，泄压支路60导通，清洗介质经过泄压支路60由内清洗部22喷出以对内部待清洗件23进行清洗。第二泄压阀14的第四预定压力的阀值压力大于第一泄压阀61的第三预定压力，因此，在不发生故障的情况下，第二泄压阀14不会动作。
根据本公开一些实施例的吸油烟机可包括根据本公开实施例的用于吸油烟机的清洗系统100。由于根据本公开实施例的用于吸油烟机的清洗系统100具有上述有益的技术效果，因此根据本公开实施例的吸油烟机可以对吸油烟机的内部和外部进行清洗，使用更加经济省力，外观更加整洁美观，并且操作更加简单方便，可以满足更多的使用需求。
下面参考图11-图22描述根据本公开另一些实施例的吸油烟机。
本公开实施例公开了一种带有可拆装的外延式喷枪的吸油烟机，能够方便用户清洗烟机内部和外部，操作方便、实用，用户使用满意度高。如图11至图14所示，该吸油烟机包括：
机壳200，该机壳200上设有机壳接口部210；
内部清洗系统，位于机壳200内；以及
外延式喷枪，通过喷枪接头部可拆卸地配对插接于机壳接口部210；
其中，喷枪接头部连接机壳接口部210时，内部清洗系统的清洗流体通过机壳接口部210引入外延式喷枪中。
可见，该外延式喷枪结合了内部清洗系统，利用配对插接的喷枪接头部与机壳接口部210，通过二者可拆卸的插拔方式往喷枪引出内部清洗系统的清洗流体，方便用户操作喷枪喷洗灶台、机壳外壁等。
外延式喷枪作为吸油烟机的附属安装配件，而非吸油烟机的主机的固有部分，因而在吸油烟机正常工作时可将外延式喷枪与主机脱离连接并收起，不影响主机美观。在需要的时候，可将外延式喷枪与主机配对插接，利用主机内的蒸汽等清洗灶台等。同样，作为外设配件，外延式喷枪和主机可独立包装、运输和维护，极为方便。
由此，在本公开的吸油烟机中，包括主机和作为外置配件的外延式喷枪，该外延式喷枪与主机之间形成易于操作的简单插拔连接，用户使用极为方便，在外延式喷枪插接于主机时，内部蒸汽清洗系统的蒸汽流体通过机壳接口部引入外延式喷枪中，极大地方便用户直接操作喷枪喷洗外部的灶台、机壳外壁等。而且作为配件的外延式喷枪可独立于主机进行运输、包装、清洗、维护等，不影响主机的外观优美。因此本公开利用内部蒸汽，以蒸汽洗方式清洗外部设备，可大大便利用户，提高用户满意度，节能环保。
在将外延式喷枪结合到蒸汽洗吸油烟机的内部蒸汽洗系统中时，如何实现外延式喷枪与主机的各自独立性和可靠性高的插拔连接，成为至为关键之处。在本公开中，特别针对性地设计了机壳接口部210和喷枪接头部，以下将结合附图分别具体阐述。
如图19所示，在该具体实施方式中，机壳接口部210包括串接于内部清洗系统的内部流体管中的流体流入接口A和流体流出内接口B1。吸油烟机还包括配件连接管220，配件连接管220的两端分别可拆卸地连接于流体流入接口A和流体流出内接口B1以导通内部流体管；其中，配件连接管220和喷枪接头部择一地连通流体流入接口A。其中，配件连接管220优选为图19中所示的U形管。
可选地，机壳接口部210固定安装于机壳200上，转接头230和配件连接管220为能够与机壳200相分离的外设配件。这样，在吸油烟机正常工作时，用户只需将配件连接管220连接于机壳接口部210上，即可保证内部清洗系统正常工作，不影响机壳美观，而外延式喷枪可收藏。在需要清洗外部灶台时，可将外延式喷枪通过喷枪接头部与机壳接口部210插接，即可将内部蒸汽流体导出以喷射清洗机壳外壁、灶台等，对于用户而言，操作方便实用。
参见图12所示，在一种可选结构中，可相互插接的转接头230和喷枪接头240构成喷 枪接头部。在图15至图18所示的实施例中，转接头230与机壳接口部210配对插接，转接头230设有流体流出外接口B2，喷枪接头240可拆卸地插接于流体流出外接口B2。另外，外延式喷枪还包括带有喷头的喷枪手持部260以及连接于喷枪手持部260与喷枪接头240的喷枪软管250。喷枪手持部260可供用户手握操作，例如开关操作。喷枪软管250用于延伸扩展喷枪的清洗范围。
本领域技术人员可以理解，根据需要，本实施例中的喷头接头240可以选用与图7中所示实施例中的外接头部312的结构相同或类似或者不同的结构，本实施例中的喷枪手持部260可以选用与图1至图3中任一个实施例中的外清洗部311中的结构相同或类似或不同的结构。
其中，在一些可选实施例中，喷枪接头240与流体流出外接口B2之间形成为防泄漏插拔，以避免内部流体向外逸散，浪费资源，增加能耗。
本领域技术人员能够理解的是，这种防泄漏插拔结构可以多种多样。参见图18和图20，在该实施方式中，流体流出外接口B2的流道内设有常闭单向阀301，常闭单向阀301设置为仅在喷枪接头240插接于流体流出外接口B2时打开阀口以导通流体流出外接口B2。具体地，在未插接状态，常闭单向阀301的常闭阀芯在内部流体压力和/或弹簧压力的作用下抵接阀口，从而封闭流体流出外接口B2。当且仅当喷枪接头240插入流体流出外接口B2中并向内顶开常闭阀芯时，方可导通流体流出外接口B2。
在一种实施方式中，采用防泄漏的机械式插拔，通过机械式插拔控制流体流向的切换，参见图20。当转接头230与机壳接口部210配对插接时，流体流入接口A同时连通流体流出外接口B2和流体流出内接口B1，并且参见图20，流体流出内接口B1的下游的内部流体管部分(即下游内部流体管L2)设有带预设背压的背压单向阀110。即，当外延式喷枪插接到位，内部流体从流体流出外接口B2流出时，背压单向阀110的预设背压可阻止内部流体流流向内部的清洗喷管5，换言之，蒸汽流全部流向喷枪。
上述的带预设背压的背压单向阀110设置在机壳接口部210外，具体为图20所示的下游内部流体管L2中。当然，背压单向阀110也可设置在机壳接口部210内部，即机壳接口部210还包括设置在流体流入接口A与流体流出内接口B1之间的流道中的带预设背压的背压单向阀110。
在一些可选实施例中，外延式喷枪的喷枪手持部260的喷出口压力应可调节，因此背压单向阀110的预设背压应足够高，或者可相应调节。但过大的预设背压将影响清洗喷管5的出口流体气压。
在另一种实施方式中，采用三通阀302以控制流体的流向切换，如图21、图22所示。
参见图15至图18，转接头230内设有三通阀302，三通阀302包括流体流入接口A连 通流体流出内接口B1的内导通位和流体流入接口A连通流体流出外接口B2的外导通位，三通阀302用于在喷枪接头240、转接头230和机壳接口部210均相互插接时执行导通位切换。
其中，三通阀302可为两位三通的电磁阀，方便自动控制，在适合条件下控制流道切换。控制切换条件或参数可以有多样，例如可以是局部压力、温度等。
图21展示了压力开关阀303作为三通阀302的切换控制阀的控制方式。参见图15至图18，转接头230内设有作为三通阀302的控制阀件的压力开关阀303，压力开关阀303用于检测流体流入接口A的流体压力并在流体压力达到预设压力阈值时控制三通阀302切换至内导通位。
具体地，在外延式喷枪拔出时，流体流出外接口B2被常闭单向阀301封堵，使得流体流入接口A上游的上游内部流体管L1的压力增大，压力增大至压力开关阀303的设定切换阈值时，将触发三通阀302执行换向动作，切换至内导通位，即导通上游内部流体管L1与下游内部流体管L2。当然，本领域技术人员公知的是，压力开关阀303仅为举例，也可采用其他控制参数的响应控制阀件，在此不再细述。
三通阀302的切换控制的另一种可行方式为机械式触发控制。根据外延式喷枪的插拔动作特性，流体流出外接口B2可设有作为三通阀302的控制阀件的微动开关33。具体地，微动开关33和微动开关触点的一者可设置在喷枪接头240上，另一者设置在图18所示的流体流出外接口B2的内部流道的周向侧壁上。当喷枪接头240与流体流出外接口B2插接到位时触发微动开关33，微动开关33在被触发状态下促使三通阀302切换至外导通位，并且在拔出外延式喷枪的非触发的复位状态下促使三通阀302切换至内导通位。
更为保险地，内部清洗系统还可包括连接流体流入接口A的上游端与流体流出内接口B1的下游端的泄压并联回路L3，如图22所示。在喷枪接头240、转接头230和机壳接口部210均相互插接时，流体流入接口A与流体流出内接口B1之间形成有机壳向内流道，泄压并联回路L3与机壳向内流道并联，泄压并联回路L3中设有常闭式泄压阀102。换言之，在外延式喷枪的正常插入或拔出时，泄压并联回路L3均通过常闭式泄压阀102保持断开状态。仅在三通阀302的切换控制失效时，上游内部流体管L1的压力增大到足以导通常闭式泄压阀102，蒸汽流体压力依次从泄压并联回路L3、下游内部流体管L2和清洗喷管5泄压流出。
泄压并联回路L3大大增强了三通阀302的可靠性。另外，在图20至图22中的各种回路中，还特别设置了泄压阀3，以进一步在管路憋压状态下通过泄压阀3直接排出管内流体，确保系统安全可靠。
另外对于各元件插接时的电路连接，特别是对于独立插拔部件，在本实施方式中，机 壳接口部210和转接头230上分别设置有配对插接的电源插头304和电源插槽部103，参见图5至图8。电源插头304和电源插槽部103插接时，不仅内部流道相互连接甚至导通，而且为转接头230内的各个控制阀件提供了电源。图5、图7可见，电源插槽部103层叠设置在包括流体流入接口A和流体流出内接口B1的流道接口部分的上方，以形成同步插接。
为便于插接操作和安装固定，机壳接口部210和转接头230分别可以形成为配对插接的固定插接盒104和移动插接盒305。如图15至图18所示，各个阀件和流道设置在插接盒的盒框内。固定插接盒104固定安装于机壳200上，移动插接盒305与固定插接盒104形状适配且可滑动导向插接，便于操作且不易出错。
前文详细介绍了外延式喷枪与吸油烟机的主机之间的插拔连接及控制。以下进一步阐述吸油烟机的内部清洗系统。内部清洗系统通常用于主要清洗离心式风机，尤其是风机中的叶轮6。清洗方式主要有水洗或蒸汽洗。
其中，结合图12、图14和图20至图22，内部清洗系统可包括用于加热以产生蒸汽的蒸汽发生器4和用于伸入蜗壳8中以清洗叶轮6的清洗喷管5，内部流体管包括位于蒸汽发生器4与流体流入接口A之间的上游内部流体管L1和位于流体流出内接口B1与清洗喷管5之间的下游内部流体管L2。其中，水泵2将水箱1中的清洗液泵入蒸汽发生器4中，经过加热形成高温蒸汽流入上游内部流体管L1，进而选择性流向外延式喷枪进行外部清洗，或者经由下游内部流体管L2流向清洗喷管5进行内部清洗。在进行内部清洗时，清洗液可通过分离过滤器7回收并循环利用。在本实施例中的蒸汽发生器4与图1至图3中所示实施例中所示的蒸汽发生器12的结构可以相同或类似，也可以不同，可以根据具体情况进行设置。
以上结合附图展示的内部清洗系统均为蒸汽清洗系统，外延式喷枪引出蒸汽流以喷洗灶台等外部设施。但本领域技术人员能够理解的是，清洗流体也可以是液体形式。此时，蒸汽发生器4可替换为加热装置，对水箱1的清洁液加热至所需温度，而后通过清洗喷管5喷淋至叶轮6上，转动叶轮6进行反复清洗。需要说明的是，吸油烟机的叶轮水洗方式及结构为公众熟知，在此不再展开细述。
在水洗方式下，外延式喷枪喷淋出清洗液，清洗方式和效果与蒸汽喷淋大致相同。
根据本公开实施例的吸油烟机和清洗系统100的其他构成以及操作对于本领域的普通技术人员来说是可知的，在此不再详细描述。
