Description

一种洗干一体机及控制方法 技术领域
本发明涉及一种洗干一体机及控制方法，属于洗干一体机及其控制方法领域。
背景技术
目前市场上的洗干一体机大都是冷凝器与外筒直接相连，使冷凝器的内腔与外筒腔连通，进而在烘干过程中，湿热的空气从外筒的出风口进入冷凝器中析出水降低湿度。如在专利201420142346.0《一种防虹吸的洗干一体机》中，如图1所示，水冷凝器6的进风口与洗干一体机的外筒5连接，且外筒5与水冷凝器6的连接点位于外筒5的中下部。在专利201520228846.0《用于洗衣机的冷凝器及具有其的滚筒洗衣机》中，如图2所示，冷凝器100与盛衣桶200即外筒相连，同样，两者相连处位于盛衣桶200的中下部。但在上述两个专利中，冷凝器进风口与外筒出风口之间并没有设置阀，在洗涤进水时无法封堵冷凝器进风口与外筒出风口之间的连接通道，当洗涤水高度超过外筒出风口高度时，洗涤水必然会进入冷凝器与外筒的连接通道及冷凝器中，而此部分水不参与洗涤，从而造成水的浪费。洗干一体机在洗涤和漂洗过程，会反复多次进水，因此导致较大量的水浪费。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种洗干一体机及控制方法，能够设置阀来控制冷凝器进风口与外筒出风口之间的连接其通断，进而能在外筒内进水时实现对通道的封闭以减少用水量。
为解决上述技术问题，本发明采用技术方案的基本构思是：
一种洗干一体机控制方法，洗干一体机接收洗涤指令，判断干衣风道与外筒之间是否导通，若否，则控制洗涤水注入外筒，进行洗涤，若是，则发出指令封闭干衣风道，并返回重新判断；洗干一体机接收干衣指令，判断干衣风道与外筒之间是否导通，若是，则控制空气在外筒和干衣风道内循环进行干衣，若否，则发出指令导通干衣风道，并返回重新判断。
进一步的，洗干一体机发出指令封闭干衣风道后，安装于冷凝器进风口与外筒出风 口之间的连接通道内的阀芯在阀杆推动下动作，封闭冷凝器进风口与外筒出风口之间的连接通道。
进一步的，冷凝器进风口与外筒出风口之间的连接通道包括拐状连接的第一通道和第二通道，第一通道一端连接外筒出风口，第二通道的一端连接冷凝器进风口，洗干一体机发出指令封闭干衣风道后，安装于第一通道内的阀芯在阀杆的推动下越过第一通道和第二通道的连接处并向第一通道与外筒出风口连接处推进，封闭冷凝器进风口与外筒出风口之间的连接通道。
一种洗干一体机，在洗干一体机内安装有外筒、冷凝器，外筒和冷凝器之间经连接通道连接形成干衣风道，在通道中安装有阀以控制其通断。
进一步的，冷凝器的进风口与外筒出风口经连接通道连接，冷凝器出风口与外筒进风口经连接通道连接，在冷凝器进风口与外筒出风口之间的连接通道上安装有阀以控制其通断。
进一步的，在冷凝器进风口与外筒出风口之间的连接通道包括呈拐状连接的第一通道和第二通道，第一通道一端连接外筒出风口，第二通道的一端连接冷凝器进风口，阀包括阀芯、阀杆，阀杆一端连接阀芯，另一端连接驱动装置，阀芯安装在第一通道内且阀芯外径与第一通道内径配合，阀杆推动阀芯在第一通道内滑动且第一通道和第二通道的相交处位于阀芯的行程内。
进一步的，在冷凝器进风口与外筒出风口之间的通道包括呈拐状连接的第一通道和第二通道，第一通道一端连接外筒出风口，第二通道的一端连接冷凝器进风口，阀包括阀芯、阀杆，阀杆一端连接阀芯，另一端连接驱动装置，阀芯安装在第二通道内且阀芯外径与第二通道内径配合，阀杆推动阀芯在第二通道内滑动且第一通道和第二通道的相交处位于阀芯的行程内。
进一步的，阀安装在连接通道内距离外筒出风口最近的位置。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明一种洗干一体机及控制方法，在冷凝器进风口与外筒出风口的连接通道上设置阀来控制其通断，通过在洗涤或烘干时先对干衣风道与外筒之间是否导通进行检测，并在向外筒中进水时将冷凝器进风口与外筒出风口之间的连接通道封闭以减少用水量，或者在烘干时打开冷凝器进风口与外筒出风口的连接通道以实现空气流通通道的畅通。

具体实施方式
实施例一
本发明洗干一体机内安装有外筒、冷凝器，外筒出风口的高度低于外筒最高点。冷凝器进风口位于冷凝器底部，冷凝器的进风口与外筒的出风口通过连接通道连接，冷凝器出风口与外筒进风口通过连接通道连接，在冷凝器与外筒的连接通道上安装有阀以控制通道的开关。
在本实施例中，在冷凝器进风口与外筒出风口之间的连接通道上安装有阀以控制其通断。阀可以采用任意一种可实现关闭或打开通道目的的阀，
阀安装在通道内距离外筒出风口最近的位置。这样，可最大限度地减少洗涤水进入通道的量。
在本实施例中，如图3所示，通道包括呈拐状连接的第一通道11和第二通道12，第一通道11一端连接外筒出风口，第二通道12的一端连接冷凝器13的进风口。阀包括阀芯14、阀杆15，阀杆15一端连接阀芯14，另一端连接作为驱动装置的电机16，阀芯14安装在第一通道11内且阀芯14的外径与第一通道11的内径配合。阀杆15推动阀芯14在第一通道11内滑动且第一通道11和第二通道12的相交处位于阀芯14的行程内，结合图3、4所示，阀杆15推动阀芯14在A位置至B位置间移动，而第一通道11和第二通道12的相交处位于A位置和B位置之间。
当洗干一体机进水时，阀杆15推动阀芯14位于A位置，阀芯14封闭了冷凝器进 风口与外筒出风口的连接通道，外筒内的水无法通过通道进入冷凝器内腔，降低了用水量。
当洗干一体机进行烘干工作时，阀杆15推动阀芯14位于B位置，阀芯14不再封闭冷凝器进风口与外筒出风口的连接通道，外筒内的空气可以通过第一通道11、第二通道12进入冷凝器13内，降低空气的湿度。此时，由于阀芯14位于第一通道11和第二通道12的相交处一侧，空气在经过第一通道11和第二通道12时，不会从阀芯14一侧经过阀芯14的另一侧，因此，不会出现空气流过阀芯14产生噪音的情况。
在其他实施例中，通道包括呈拐状连接的第一通道和第二通道，第一通道一端连接外筒出风口，第二通道的一端连接冷凝器的进风口，阀包括阀芯、阀杆，阀杆一端连接阀芯，另一端连接驱动装置，阀芯安装在第二通道内且两者配合，阀杆推动阀芯在第二通道内滑动且第一通道和第二通道的相交处位于阀芯的行程内。阀杆通过推动阀芯在第一通道和第二通道的相交处两侧停留实现冷凝器进风口与外筒出风口的连接通道的通或断。
本发明一种洗干一体机在冷凝器进风口与外筒出风口的连接通道上设置阀来控制其通断，在外筒内进水时对通道封闭以减少用水量，或者烘干时打开冷凝器进风口与外筒出风口的连接通道以实现空气流通通道的畅通。
实施例二
一种洗干一体机控制方法，在实施例一所述的洗干一体机上实施，洗干一体机接收洗涤指令，判断干衣风道与外筒之间是否导通，若否，则控制洗涤水注入外筒，进行洗涤，若是，则发出指令封闭干衣风道，并返回重新判断；洗干一体机接收干衣指令，判断干衣风道与外筒之间是否导通，若是，则控制空气在外筒和干衣风道内循环进行干衣，若否，则发出指令导通干衣风道，并返回重新判断。
本实施例所述干衣风道包括实施例一所述的冷凝器进风口与外筒出风口的连接通道在内的空气所流经的通道。但此干衣风道的通断由安装在冷凝器进风口与外筒出风口之间的连接通道上的阀来控制。
在本实施例中，洗干一体机发出指令封闭干衣风道后，安装于冷凝器进风口与外筒出风口之间的连接通道内的阀芯在阀杆推动下动作，封闭冷凝器进风口与外筒出风口之间的连接通道。
由于冷凝器进风口与外筒出风口之间的连接通道包括拐状连接的第一通道和第二通道，第一通道一端连接外筒出风口，第二通道的一端连接冷凝器进风口，洗干一体机 发出指令封闭干衣风道后，安装于第一通道内的阀芯在阀杆的推动下越过第一通道和第二通道的连接处并向第一通道与外筒出风口连接处推进，封闭冷凝器进风口与外筒出风口之间的连接通道。为了使阀芯封闭后的连接通道尽可能少地容纳水，阀芯尽可能地向第一通道与外筒出风口连接处推进。
本发明一种洗干一体机控制方法，利用在冷凝器进风口与外筒出风口的连接通道上设置的阀来控制其通断，在洗涤或烘干时先对干衣风道与外筒之间是否导通进行检测，在外筒内进水时对通道封闭以减少用水量，或者烘干时打开冷凝器进风口与外筒出风口的连接通道以实现空气流通通道的畅通。
上述实施例中的实施方案可以进一步组合或者替换，且实施例仅仅是对本发明的优选实施例进行描述，并非对本发明的构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中专业技术人员对本发明的技术方案作出的各种变化和改进，均属于本发明的保护范围。
