Description

衣物护理机
本申请要求在2021年6月28日提交国家知识产权局、申请号为202121452500.0的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及家用电器技术领域，例如涉及一种衣物护理机。
背景技术
随着生活水平的提高，人们对衣物护理的需求也日益趋向个性化与多元化，尤其针对一些特殊材质以及一些不适合经常水洗的衣物，对衣物清洗、护理的要求也越来越高，衣物护理机应运而生。
衣物护理机一般包括蒸汽发生装置(也称锅炉)和护理箱。蒸汽发生装置生成的蒸汽进入护理箱内，蒸汽进入衣物深层抚平褶皱，且蒸汽渗入到衣物纤维深层进行杀菌，并带走衣物内残留的气味，实现对衣物的去皱、杀菌和去味。
蒸汽是通过锅炉底部的加热管对锅炉内的水加热而产生的。一方面，在水的加热过程中，水内溶解的空气会受热析出，产生大量气泡，一部分汽化的水也会以气泡的形式出现。这些气泡破裂时与锅炉共振，产生较大的噪声。另一方面，锅炉内的水一般会加入用于除菌、除味等的添加剂。这些添加剂会增大水的表面张力，使得在水沸腾时，锅炉中容易出现喷水现象。严重时，水会沿着管路喷入护理箱内，污染护理箱。
发明内容
本申请提供一种衣物护理机，以缓解相关技术的衣物护理机所存在的锅炉噪声以及喷水问题。
本申请所采用的一个技术方案是：提供一种衣物护理机。该衣物护理机包 括蒸汽发生装置、加热器、温度传感器和控制器。蒸汽发生装置用于容纳液体。加热器用于加热液体以生成蒸汽。温度传感器设置在蒸汽发生装置中，用于感测液体的温度。控制器接收来自温度传感器的信号并且控制加热器。当温度传感器感测到液体的温度在第一温度和第二温度之间时，控制器将加热器切换到断续工作状态。其中，第一温度和第二温度都小于液体的沸点。
区别于相关技术，本申请通过当温度传感器检测到锅炉中的水温在低于沸点的第一温度和第二温度之间时，控制器控制加热器以间断状态工作，缓解了锅炉噪声以及喷水问题。

下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
参考图1和图2，图1示出衣物护理机10的侧视示意图，图2示出衣物护理机10的正视示意图。
如图1和图2所示，衣物护理机10包括壳体100、护理箱200以及蒸汽发生装置300。护理箱200和蒸汽发生装置300都容纳于壳体100内。在一实施例 中，蒸汽发生装置300设置于护理箱200的下方。
如图1和图2所示，护理箱200具有容纳空腔210。护理箱200的底部设置有与容纳空腔210流体连通的蒸汽入口220，用于接收来自蒸汽发生装置300的蒸汽。
容纳空腔210可以容纳需要护理的衣物。具体地，护理箱200的内部顶端，即容纳空腔210的内部顶端，设置有衣物支架230，用于悬挂衣物。图2中所示的衣物支架为挂衣杆，本领域技术人员根据具体用途也可以设置其他类型的衣物支架230，本申请对此不作限制。护理箱200的一侧还设置有门体240，用于打开和/或关闭容纳空腔210，以取放衣物。
蒸汽发生装置300设置在护理箱200的底部，用于加热诸如水的液体以产生蒸汽。下文以水作为液体的具体实施例进行描述。蒸汽发生装置300例如为锅炉300。加热器400贴附在锅炉300的底壁上，用于为锅炉300提供加热液体所需的热量。锅炉300的底壁为热的良导体，用于将来自加热器400的热传递给锅炉300内的水。加热器400也可以设置在锅炉300内且与水直接接触，本申请对此不作限制。蒸汽发生装置300设置有蒸汽出口310。蒸汽输送管500流体连通地连接在护理箱200的蒸汽入口220与蒸汽发生装置300的蒸汽出口310之间。
在衣物护理机10工作时，加热器400加热锅炉300中的液体以产生高温蒸汽。高温蒸汽从锅炉300的蒸汽出口310流出，依次经过蒸汽输送管500和护理箱200的蒸汽入口220进入容纳空腔210内。高温蒸汽可在容纳空腔210内润湿和熨烫衣物，以及对衣物杀菌。
在一实施例中，在锅炉300的水中添加诸如用于除菌、除味等的添加剂。这些添加剂可以随着高温蒸汽进入容纳空腔210内，以参与对衣物的护理，增加衣物的护理效果。
进一步参考图1和图2，衣物护理机10还包括净水箱600和/或废水箱700。在一实施例中，净水箱600和/或废水箱700设置在护理箱200的底部。如图1 所示，净水箱600和废水箱700堆叠放置在衣物护理机100的一侧，且净水箱600置于废水箱700上方。
净水箱600用于提供锅炉300所需的水。用户可以将水注入净水箱600中。净水箱600可以对注入的水执行沉淀、软化等操作，以过滤水中的杂质、减少锅炉中的水垢等。净水箱600经过净水泵620和净水管630与锅炉300流体连通。净水泵620可以将净水箱600中的水泵送到锅炉300中。
通过设置净水箱600和净水泵620，不仅可以对注入衣物护理机10中的水进行过滤、软化等操作，还可以根据需要控制锅炉300中的水量。
护理箱200的底部包括集水区250。如图2所示，护理箱200的底部包括集水区250。集水区250的底部包括废水出口252。废水出口252经废水管710和废水泵720与废水箱700流体连通。
在衣物护理机10工作时，在容纳空腔210中，高温蒸汽冷凝形成废水。废水在重力的作用下例如通过过滤器660流入集水区250中，之后经废水出口252、废水管710和废水泵720流入废水箱700内。废水泵720可以提供抽取废水的动力。
如图2所示，衣物护理机10还包括控制器(也称控制板)800。控制器800用于控制加热器400等的操作。
参考图3，图3示出根据本申请一实施例的锅炉300的横截面示意图。如图所示，锅炉300包括用于进水的进水口320和用于排放蒸汽的蒸汽出口310。
具体地，来自净水箱600的水经进水口320注入锅炉300中。或者说，进水口320经过净水泵620和净水管630与净水箱600流体连通。蒸汽出口310与蒸汽输送管500流体连通，用于经蒸汽输送管500输出蒸汽。
如图3所示，温度传感器组件900至少部分设置在锅炉300内，以感测锅炉300内的水温。温度传感器组件900包括传感器外壳910和设置于传感器外壳910中的温度传感器920。
传感器外壳910由耐高温塑胶或金属制成。传感器外壳910可通过螺纹连 接在锅炉300的侧壁上，尤其是锅炉300的顶壁上，以便于拆装。传感器外壳910可以支撑、固定和保护温度传感器920。
温度传感器920可以是半导体温度计920。半导体温度计920由半导体材质构成，其利用半导体材质的电阻与温度之间的对应关系来测量温度的变化。如图3所示，半导体温度计920设置于传感器外壳910内靠近水的一端，以便于测量锅炉中的水温。
参考图4和图5，图4示出根据本申请一实施例的控制板800的工作原理的示意图，图5示出根据本申请一实施例的控制板800的示意图。如图所示，控制板800可与温度传感器920通信连接，以接收来自温度传感器920的温度信号。控制板800还可与温度传感器920电性连接，以为温度传感器920供应工作所需的电力。进一步，控制板800可与加热器400电性连接，从而为加热器400提供工作所需的电力。
如上文所述，在锅炉300工作时，温度传感器920检测锅炉内的水温，并且将表征水温的温度信号传输给控制板800。
一般而言，在锅炉300中的水开始被加热时，控制板800控制加热器400处于持续工作状态，以持续加热锅炉中的水，水温从常温(例如20℃)逐渐升高。
当水温升高到第一温度时，控制板800将加热器400切换到断续工作状态。该第一温度例如在50℃与70℃之间，可选地为65℃。在断续工作状态中，加热器400周期性地工作。在每个周期内，加热器400加热第一时间段，随后停止加热第二时间段。第一时间段例如为10秒。第二时间段例如为10秒。第一时间段和第二时间段也可以为用户根据具体实施例确定的其他值，本申请对此不作限制。
本申请通过断续加热锅炉中的水，使得主要在第一时间段中的加热中析出的气泡有充足的时间从水中排出，不会造成气泡的大量积聚，有效降低了水在沸腾前的噪声，缓解了锅炉中的喷水现象。
随着加热的进行，水温进一步升高。当水温升高到第二温度时，控制板800将加热器400切换到持续工作状态。第二温度高于第一温度。在一实施例中，第二温度在90℃与95℃之间。在一实施例中，第二温度为95℃。在高于第二温度时，锅炉300中的水产生大量高温蒸汽，以进行衣物的护理。
参考图5，控制板800包括第一切换开关400、第一电路810、第二电路820以及加热器开关850。第一切换开关400连接于温度传感器920，用于接收来自温度传感器920的温度信号。第一切换开关400还连接于第一电路810和第二电路820，以分别切换第一电路810和第二电路820的通断状态。加热器开关850电性连接于加热器400，用于为加热器400提供工作电流，且控制加热器400的打开或关闭。第一电路810连接于加热器开关850，用于使加热器开关850处于断续接通状态，继而控制加热器400处于断续工作状态。第二电路820连接于加热器开关850，用于使加热器开关850处于持续接通状态，继而控制加热器400处于持续工作状态。
在一些实施例中，加热器开关850为继电器或可控硅开关。
具体地，当温度传感器920检测到锅炉300中的水温在第一温度和第二温度之间时，温度传感器920将温度信号发送到控制板800的第一切换开关400。第一切换开关400控制第一电路810导通，第二电路820断开，以使加热器开关850处于断续接通状态或间歇接通状态，从而控制加热器400处于断续工作状态。当温度传感器920检测到锅炉300中的水温低于第一温度或者高于第二温度时，控制板800控制第二电路820导通，第一电路810断开，以使加热器开关850处于持续接通状态，从而控制加热器400处于持续工作状态。
参考图6，图6示出根据本申请一实施例的锅炉1300的横截面示意图。如图6所示，与图3中的锅炉300相比，搅拌器350还设置在锅炉1300内。搅拌器350的一端固定连接于锅炉1300的侧壁。搅拌器350还包括叶片352。在搅拌器350工作时，搅拌器350的叶片352旋转以搅动锅炉1300中的水。
参考图7和图8，图7示出根据本申请又一实施例的控制板1800的工作原 理的示意图，图8示出根据本申请又一实施例的控制板1800的示意图。
与图4和图5中的控制板800相比，控制板1800还可与搅拌器350电性连接，从而为搅拌器350提供工作所需的电力，且控制搅拌器350的打开或关闭。在如上文所述的第二时间段中，控制板1800控制搅拌器350工作，以搅拌锅炉中的水。
如图8所示，与图5中的控制板800相比，控制板1800还包括第三电路830以及搅拌器开关860。第三电路830连接于搅拌器开关860，用于使搅拌器开关860处于断续接通状态，继而控制搅拌器350处于断续工作状态。第三电路830还连接于第一切换开关400，以使第一切换开关400能够切换第三电路830的通断状态。搅拌器开关860电性连接于搅拌器350，用于为搅拌器350提供工作电流，且控制搅拌器350的打开或关闭。
在一些实施例中，搅拌器开关860为继电器或可控硅开关。
具体地，当温度传感器920检测到锅炉1300中的水温在第一温度和第二温度之间时，温度传感器920将温度信号发送到控制板1800的第一切换开关400。第一切换开关400控制第三电路830导通，以使搅拌器开关860处于断续接通状态或间歇接通状态，从而控制搅拌器350处于断续工作状态。具体地，在断续工作状态中，在第一时间段中，加热器400加热，搅拌器350停止工作，在第二时间段中，加热器400停止加热，搅拌器350启动搅拌。也就是说，在断续工作状态中，加热器400和搅拌器350交替工作。
该实施例通过在第二时间段中利用搅拌器搅拌锅炉中的水，不但促使气泡在停止加热时从水中排出，还使得水温的分布更加均匀，进一步缓解了锅炉中的喷水现象。
