本发明属于家用电器领域，具体提供一种具有透气功能的洗衣机及其控制方法。
背景技术
目前的滚筒洗衣机在不工作并且机门被关闭时，外筒内形成密封空间，长时间后外筒内会发霉产生异味以及外筒内橡胶制件会形成严重的刺激性气味，影响用户的使用体验。目前的解决方案主要有两种，其一是，提醒用户使用完毕后，不要将机门完全关闭，使机门和外筒之间保留一定的缝隙。但是，此方案可控性太差，用户使用极不方便。其二是，在前板上增加弹性机构，可以将门体推开一定距离，使外筒内不能形成密封空间。但是，此方案将门体推开一定距离，将导致门体占用一部分空间，并且此时门体是活动的，给人一种不安全、不稳定的感觉，可能会导致用户强制将门体关闭，进而失去透气效果。
相应地，本领域需要一种新的洗衣机结构来解决上述问题。

具体实施方式
本领域技术人员应当理解的是，本节描述的实施方式仅仅用于解释本发明的技术原理，并非用于限制本发明的保护范围。例如，虽然说明书是结合附图以滚筒洗衣机为例来对本发明的技术原理进行说明的，但是本发明的技术原理还可以适用于其他结构的洗衣机，例如波轮洗衣机，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
需要说明的是，在本发明的描述中，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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发明的限制。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1至图4所示，本发明的具有透气功能的洗衣机主要包括机体1、容纳在机体1内的外筒2和枢转地设置在外筒2内的内筒3。其中，机体1上形成有第一透气通道4。第一透气通道4的第一端41通向洗衣机的外部环境(例如室内环境)，第一透气通道4的第二端42通向外筒2的内部(具体是外筒2与内筒3之间的空间)，以便外筒2与外部环境能够通过第一透气通道4彼此连通，使得外部环境中的空气能够进入外筒2的内部，外筒2内的异味能够及时地发散到外部环境中，改善用户的使用体验。本领域技术人员能够理解的是，外筒2内的异味主要是外筒2内的洗涤剂残留物、洗衣粉残留物、纤维等长期处于密闭环境中而发霉产生的异味，以及外筒2内的橡胶制件长期处于密闭环境中而形成的刺激性气味。
如图1所示，机体1的前表面上设置有前板11，该前板11可以以任何可行的连接方式连接到机体1的前表面上，例如卡扣连接、焊接、铆接、螺钉连接等。此外，本领域技术人员还可以根据需要，使前板11一体地形成到机体1上。进一步，机体1的前表面还枢转地连接有门体5。
继续参阅图1至图4，第一透气通道4的第一端41形成到前板11上。并且，在门体5被关闭时，门体5能够覆盖或遮挡第一透气通道4的第一端41，从而能够提高洗衣机整体的美观性。关于此点，需要指出的是，这里的“覆盖或遮挡”意思是门体5的径向延伸范围涵盖了第一透气通道4的第一端41所在的位置，而不是指门体5直接封闭第一透气通道4的第一端41，这点将在下文更详细地描述。第一透气通道4的第二端42形成在外筒2的前端(图4中所示外筒2的右端)的上部，或者本领域技术人员还可以根据需要，将第一透气通道4的第二端42设置到外筒2上的其他部位，例如外筒2周向上的顶部。进一步，第一透气通道4的第一端41在垂直方向上的高度大于第一透气通道4的第二端 42在垂直方向上的高度，以便防止第一透气通道4内的水分(这里主要指冷凝水)流到洗衣机外部。
需要说明的是，除了前板11上被门体5覆盖的位置之外，第一透气通道4的第一端41还可以设置到机体1的其他位置上，例如，机体1的两个侧板、后板或顶部台面上。此外，本领域技术人员还可以根据需要，对位置调整之后的第一透气通道4的第一端41设置遮挡件，以保证洗衣机整体上的美观性。由于洗衣机在使用过程中，洗衣机的侧板和/或后板通常会临近墙体，所以位置调整之后的第一透气通道4的第一端41在没有遮挡件的情况下，也不会影响洗衣机整体的美观性。
如图3、图5和图8所示，本发明的洗衣机还包括第一控制开关6，该第一控制开关6用于打开或关闭第一透气通道4的第一端41。具体地，该第一控制开关6能够在门体5关闭并且洗衣机开机时关闭第一透气通道4的第一端41，在门体5关闭且洗衣机关机时打开第一透气通道4的第一端41。更具体地，第一控制开关6可以与洗衣机的主控板(未图示)连通，当主控板收到的检测信息显示门体5关闭并且洗衣机开机时，第一控制开关6就关闭第一透气通道4的第一端41以便保证洗衣机的正常运行，尤其是洗涤操作的正常运行；当主控板收到的检测信息显示门体5关闭且洗衣机关机时，第一控制开关6就打开第一透气通道4的第一端41以便使外筒内部能够实现透气从而散发异味和霉味。
下面结合图2至图6来对本发明的第一实施例进行说明。
如图4和图6所示，门体5上设置有第一透气开口51，在门体5被关闭的状态下，图4中第一透气开口51的左端能够与第一透气通道4的第一端41对准并密封连通。进一步，第一控制开关6被设置到门体5上，主要包括遮挡件61和与该遮挡件61连接的电磁阀62。具体地，遮挡件61以枢转或滑动方式设置到门体5内，电磁阀62能够驱动遮挡件61转动或滑动，使遮挡件61在关闭位置(图4中遮挡件61的位置)和打开位置(图6中遮挡件61的位置)之间切换。在门体5关闭的状态下，当遮挡件61切换到关闭位置时，第一透气开口51被截断，使得第一透气通道4与外部环境的连通被阻断；当遮挡件61切换到打开位置时，第一透气开口51被打开，使得第一透气通道4与外部环境连通。
进一步，与第一透气通道4的第一端41的设置位置相对应，本领域技术人员还可以根据需要，将第一控制开关6设置到机体1或门 体5上的其他位置，只要第一控制开关6能够在门体5关闭并且洗衣机开机时关闭第一透气通道4的第一端41、在门体5关闭且洗衣机关机时打开第一透气通道4的第一端41即可，这种变化和调整并不偏离本发明的原理和保护范围。
更进一步，本领域技术人员还可根据需要，在第一控制开关6上增设复位弹簧(附图中未示出)，并使该复位弹簧与遮挡件61操作连接，使复位弹簧能够驱动遮挡件61朝被打开的位置移动，从而使第一透气通道4与外部环境连通。当需要阻断第一透气通道4与外部环境的连通时，电磁阀62被通电从而克服复位弹簧的弹力，驱使遮挡件61朝被关闭的位置移动。本领域技术人员容易理解的是，复位弹簧能够使第一控制开关6在洗衣机关闭时自动地将外筒2与外部环境通过第一透气通道4进行连通，而电磁阀62能够使第一控制开关6在洗衣机开机且门体关闭时自动地断开外筒2与外部环境的连通，防止外筒2内的水从第一透气通道4流到外部环境。
关于第一实施例，需要说明的是，之所以在门体5上设置第一透气开口51，一方面是为了方便对第一透气通道4进行通断操作，另一方面也能为用户提供可视化的功能识别，随时提醒用户本发明的洗衣机具备关机透气功能。
下面结合图7来对本发明的第二实施例进行说明。
如图7所示，与第一实施例不同的是，本实施例的第一透气开口51不直接与外部环境连通，而是借助设置在门体5上的辅助透气通道52和第二透气开口53与外部环境连通。具体地，辅助透气通道52被设置在门体5的内部，第二透气开口53被设置在门体5的外周上并与外部环境连通，辅助透气通道52将第一透气开口51与第二透气开口53连通。进一步，辅助透气通道52优选地被设置为圆弧形，即辅助透气通道52在门体5内的延伸方向呈弧形，并且辅助透气通道52的中间部分与第一透气开口51连通，辅助透气通道52的两端分别连接两个第二透气开口53。此外，本领域技术人员还可以根据需要，将辅助透气通道52设置成其他形状，例如条形、S形、V形等；在门体5上设置其他数量的第二透气开口53并与辅助透气通道52连通，例如一个、三个、四个等。示例性地，当门体5上只设置有一个与辅助透气通道52连通的第二透气开 口53时，辅助透气通道52的两端分别与第一透气开口51和第二透气开口53连通。
从上述内容不难看出，相对于第一实施例，第二实施例能够有效地对第一透气通道4的第一端41进行隐藏，保证了洗衣机整体的美观性，并且在用户打开门体5时，第二透气开口53还会提醒用户本发明的洗衣机具备关机透气功能。
下面结合图8、图9、图10、图11和图12来对本发明的第三实施例进行说明。
如图10和图12所示，与第一实施例不同的是，在本实施例中门体5上未设置第一透气开口51。具体地，在本实施例中，第一控制开关6同样被设置到门体5上，主要包括闭塞构件63、复位弹簧64和电磁阀(图中未示出)。其中，闭塞构件63的形状与第一透气通道4的第一端41相匹配，并且在图10中闭塞构件63的右端设置有凸缘结构(图中未标示)。门体5的左侧板上设置有通孔，该通孔的尺寸大于闭塞构件63的左端的尺寸且小于闭塞构件63右端的凸缘结构的尺寸，以便闭塞构件63的左端能够穿过该通孔，而闭塞构件63右端的凸缘结构不能够穿过该通孔，防止闭塞构件63从门体5上滑脱。进一步，当闭塞构件63向图10中的左侧滑动时，闭塞构件63的左端能够与第一透气通道4的第一端41接合，进而将第一透气通道4的第一端41关闭。当闭塞构件63向图12中的右侧滑动时，闭塞构件63的左端脱离第一透气通道4的第一端41，使第一透气通道4的第一端41通过门体5与前板11之间的缝隙与外部环境连通。
继续参阅图10和图12，复位弹簧64与闭塞构件63操作连接。具体地，复位弹簧64套设在闭塞构件63的外侧，并且复位弹簧64的左端与门体5的左侧板的内表面相抵，复位弹簧64的右端与闭塞构件63的凸缘结构的左端面相抵。在闭塞构件63的左端与第一透气通道4的第一端41接合时，复位弹簧64在电磁阀的作用下处于压缩状态，以便在电磁阀被断电时能够推动闭塞构件63向右滑动，使闭塞构件63脱离与第一透气通道4的接合，进而使第一透气通道4与外部环境连通。
虽然图中并未示出，但是电磁阀与闭塞构件63相连接，在电磁阀通电时，电磁阀能够克服复位弹簧64的弹力驱动闭塞构件63向左滑动直至与第一透气通道4的第一端41相接合，使第一透气通道4与 外部环境的连通被断开。此外，本领域技术人员还可以根据需要，省去复位弹簧64的设置，使电磁阀直接驱动闭塞构件63向左移动和向右移动，并且电磁阀还能够使闭塞构件63保持在关闭位置和打开位置。或者使复位弹簧64驱动闭塞构件63关闭第一透气通道4的第一端41，使电磁阀克服复位弹簧64的弹力驱动闭塞构件63打开第一透气通道4的第一端41。再者，尽管本申请中描述的是电磁阀和复位弹簧，但是这并不是限制性的，本领域技术人员可以根据需要采用其他驱动构件或复位构件，这种变化并不偏离本发明的原理和范围。
从上述内容不难看出，相对于第一实施例，第三实施例能够有效地对第一透气通道4的第一端41进行隐藏，保证了洗衣机整体的美观性，更适用于对透气功能的可识别性没有要求，但是对洗衣机的外观整洁性和美观性有要求的用户群体。
本领域技术人员能够理解的是，在本发明的第一实施例和第三实施例的技术方案中，当门体5处于关闭状态且洗衣机处于关闭状态时，第一控制开关6能够自动切换到打开位置，使外筒2通过第一透气通道4与外部环境连通；当门体5处于关闭状态且洗衣机处于开机状态时，第一控制开关6通电能够自动切换到关闭位置，使外筒2与外部环境的连通被阻断。因此，本发明的洗衣机即便是长期不使用时外筒2内也不会产生异味，从而提高了用户的使用体验。
需要说明的是，虽然本发明的第一实施例和第三实施例只描述了一个第一透气通道4，但是本发明的第一透气通道4还可以是任意多个，并且每个第一透气通道4都独立地配置有一个第一控制开关6。此外，本领域技术人员还可以根据需要，将第一透气通道4设置在机体1上的侧板、后板或顶部台面上，或者也可以在前板11上被门体5覆盖的位置设置多个第一透气通道4，以便提高洗衣机在关闭状态下的透气能力。
如图3、图5、图8和图11所示，本发明的具有透气功能的洗衣机可选地还包括第二透气通道7和第二控制开关8。第二透气通道7优选地设置在机体1上远离第一透气通道4的一端。优选地，第二透气通道7连接到外筒2的后端。具体地，第二透气通道7的第一端(图8中第二透气通道7的左端)形成在机体1的后板上并通向外部环境，第二透气通道7的第二端(图11中第二透气通道7的右端)形成在外筒2上并通向外筒2的内部(具体是外筒2的后端)。或者本领域技术人员 还可以根据需要，将第二透气通道7设置到洗衣机上的其他位置，例如，使第二透气通道7的第一端形成在机体1的侧板或前板上，使第二透气通道7的第二端形成在外筒2的周向位置或前端上。第二控制开关8设置在第二透气通道7中，用于打开或关闭第二透气通道7，使外筒2与外部环境连通或隔离。本领域技术人员能够理解的是，与第一透气通道4类似地，第二透气通道7也可以是多个，并且每个第二透气通道7都独立地配置有一个第二控制开关8，或者使多个第二透气通道7共同配置一个第二控制开关8。
如图13和图14所示，图12示出的是第二控制开关8处于关闭位置的状态，图14示出的是第二控制开关8处于打开位置的状态。作为示例，第二控制开关8主要包括挡板81和控制阀82，挡板81设置在第二透气通道7中；控制阀82与挡板81相连接，用于驱动挡板81移动，使第二透气通道7被打开或关闭。此外，本领域技术人员还可以根据需要，将第二控制开关8设置为与图3和图4所示的第一控制开关6具有相同结构。或者，本领域技术人员还可以根据需要，将第二控制开关8和第一控制开关6设置成其他具有通断功能的开关。
本领域技术人员能够理解的是，第二透气通道7的设置能够使外筒2和外部环境之间借助第一透气通道4和第二透气通道7形成一个循环的透气回路，从而能够提高外筒2的内部与外部环境之间的空气流通能力，更有效地避免外筒4内部产生异味的问题。
此外，需要说明的是，第一透气通道4和第二透气通道7可以是由任何可行的结构构成的通道，例如由柔性软管构成的通道、由钣金折弯焊接成型的通道、一体地成型到机体1上的通道等。并且，当本发明的洗衣机同时设置有第一透气通道4和第二透气通道7时，根据使用环境的不同，它们中的任一个可以用于进气，另一个可以用于排气。类似地，当本发明的洗衣机(例如其前板11)上同时设置有多个第一透气通道4时，它们中的任一个或多个可以用于进气，其他透气通道可以用于排气。上述具体透气功能的变化并不偏离本发明的原理，因此都将落入本发明的保护范围之内。
在另一方面，本发明提供了一种控制上述具有透气功能的洗衣机的方法，该控制方法主要包括以下步骤：检测门体5的开闭状态； 检测洗衣机的开关状态；基于门体5的开闭状态和洗衣机的开关状态，选择性地打开或关闭第一透气通道4的第一端41。
具体地，当检测到门体5关闭并且洗衣机开机时，关闭第一透气通道4的第一端41。当检测到门体5关闭且洗衣机关机时，打开第一透气通道4的第一端41。需要说明的是，上文所述的洗衣机的开机状态包括开机运行状态和开机未运行状态，开机运行状态又包括洗涤状态、排水状态、脱水状态等。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
