用于空调器的空气清洁控制方法及空调器 技术领域

背景技术
随着人们生活水平的提高，越来越多的人使用空调器，人们对空调的送风质量要求也越来越高，然而在使用空调器的房间中，为了达到最佳的换热效果，室内的门窗是关闭的，这样会造成空气不流通，时间长了会导致人体憋闷不舒服，主要是因为长时间关窗导致室内的空气质量变差，空气较为污浊导致的。
目前，在开启空调器时，对室内的空气进行清洁的方式通常包括：选择安装新风机或使用带有新风功能的空调器等产品，通过引入室外的空气来达到换气的目的，从而保证室内空气“新鲜”，然而，带有新风功能的空调器价格通常较高，并且采用引进新风的方式，在冬季或夏季会造成室内局部过冷或者过热，影响用户体验度，此外，还需要经常更换净化滤芯、热交换滤芯等耗材，后期的维护成本较高。

具体实施方式
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。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。
如图1、图2和图3所示，为解决现有空调器运行时，容易导致室内的空气质量变差的问题，本发明的空调器包括室内机1，室内机1包括气流通道11、进气阀12、排气阀13、送风机14、人数检测模块和浊气吸附与释放单元15，气流通道11包括进气通道111和排 气通道112；进气通道111与排气通道112连通，进气通道111的两端均设置在室内，排气通道112与进气通道111连通的一端设置在室内，另一端设置在室外，进气阀12设置在进气通道111上，以实现进气通道111的独立开闭，排气阀13设置在排气通道112上，以实现排气通道112的独立开闭；送风机14和浊气吸附与释放单元15均设置在气流通道11内，并且设置成在送风机14开启时，当进气阀12开启、排气阀13关闭时，室内空气经浊气吸附与释放单元15的吸附过滤后重新进入室内；在送风机14开启时，当进气阀12关闭、排气阀13开启时，室内空气流经浊气吸附与释放单元15，然后将吸附的浊气或浊物排出至室外；其中，浊气吸附与释放单元15用于吸附或释放浊气或浊物，本领域人员可以理解的是，进气通道111为由进气通道入口1111至进气通道出口1112之间气流流经的通道；排气通道112为由进气通道入口1111至排气通道出口1122之间气流流经的通道。
上述设置方式的优点在于：通过上述设置方式，使得本发明的空调器具有净化室内空气的功能，当需要进行空气清洁时，将进气阀12打开，排气阀13关闭，此时，室内的空气在送风机14的作用下，由进气通道入口1111进入，并经过浊气吸附与释放单元15将其中的浊气或浊物吸附，例如，CO 2，此时，室内空气已经被净化，经过净化的空气再经过进气通道出口1112重新回到室内，以使室内的空气得到清洁；为了达到更好的吸附效果，或者浊气吸附与释放单元15无法进行正常吸附时，此时，将进气阀12关闭，排气阀13开启，在送风机14的作用下，能够将浊气吸附与释放单元15上吸附的浊气或浊物经过排气通道出口1122排出至室外，其中，图1和图2所示的为排气出口1121，通过与排气管的连接能够将浊气或浊物引出至室外，则此种情况下，排气通道出口1122设置在排气管的室外端，本发明的空调器通过浊气吸附与释放单元15能够对浊气或者浊物进行吸附以及释放，相比于现有技术使用新风机的滤芯进行新风的净化操作，本发明的空调器无需使用耗材，浊气吸附与释放单元15能够重复使用，节约了使用成本，此外，本发明的空调器为通过引入室内的空气进行净化工作，相比于现有技术中引入新风模式，无需进行热量交换，能够避免换热模块的频繁启动，从而降低其寿命，且无需使用热交换滤芯等 耗材，降低维护使用成本，此外，还能够避免室内局部过冷或者过热的现象出现。
在一种可能的实施方式中，排气通道112的排气管的直径小于等于30mm。
上述设置方式的优点在于：现有技术中，带有新风功能的空调器与室外连通的新风管的直径较大，一般在100mm至200mm之间，因此，新风管在与室外进行连通时，由于需要大量的空气流动来实现换气，需要在墙体上单独打一个较大的孔洞，从而造成对墙体的破坏，而本发明的浊气吸附与释放单元无论哪种具体的实施方式，均只需将吸附的浊气或浊物排出，无需大量的新风进入或排出，只需要极小量的空气流动，因此排气管可以设置的较细，其直径小于等于30mm，可以与墙体上的空调联机管的孔洞共同使用，无需单独打孔，还能够降低安装成本。
此外，当浊气吸附与释放单元具体包括固态胺吸附块和加热模块时，固态胺的特性是能够在常温下吸附CO 2，在加热后释放CO 2，如图4所示，并继续参照图3，本发明还提供了一种用于空调器的空气清洁控制方法，具体包括如下步骤：
步骤S1：开启进气阀12、关闭排气阀13，然后开启送风机14。
当需要进行室内的空气清洁时，将进气阀12开启，排气阀13关闭，即此时进气通道111畅通，在送风机14的作用下，将室内的污浊空气引入到浊气吸附与释放单元15中，经过对CO 2的吸附后，在送风机14的作用下，将清新的空气排入室内，进而保证室内的空气质量。
作为一种优选的实施方式，执行步骤S1的条件包括：当接收到用户发来的除CO 2信息指令时，执行步骤S1，其中，用户可以通过遥控器、空调面板或者智能终端等发出信息指令；当然，也可以通过空调器的自动检测，即当检测到的CO 2浓度≥预设浓度值时，例如，达到表1中的level3和level4时，执行步骤S1。
此外，一般情况下，用户并不清楚室内的CO 2浓度，本发明通过展示检测到的CO 2浓度信息给用户，以便用户知晓室内CO 2浓度，其中展示的方式包括多种形式，例如，通过空调面板、遥控器显示屏、智能终端或者语音等形式，当然，可以按照预设频次进行CO 2 浓度信息的展示，也可以实时更新显示CO 2浓度信息给用户，以便用户更好的感知。
其中，本发明的空调器室内机1同时集成有CO 2检测模块，能够检测环境中的CO 2浓度，作为一种优选的实施方式，CO 2检测模块设置在空调器的室内风进风口处(用于使空气在空调器内进行换热的进风口)，室内的空气经过进风口进入空调，经过CO 2检测模块检测室内空气质量，并将检测结果以电信号传送给空调。
步骤S2：控制人数检测模块检测室内人数。
本发明的空调器室内机1集成有人数检测模块，能够检测室内的人数，作为一种优选的实施方式，人数检测模块可以为红外检测器或者摄像头等。
步骤S3:根据检测到的室内人数，控制送风机14选择不同的转速运行。
本发明的空调器通过检测到的室内人数，控制送风机14选择不同的转速运行，以达到不同的CO 2的吸附速率，例如，当室内人数较多时，室内产生CO 2的速率会较高，因此，此时可以提高送风机14转速来提高CO 2的吸附效率，保证室内空气质量，使本发明的空调器更加的智能化，以达到良好的用户体验度。
步骤S4：开启排气阀13、关闭进气阀12，并控制浊气吸附与释放单元15释放浊气或浊物。
当需要进行CO 2的释放时，通过排气阀13的开启，进气阀12的关闭，即此时排气通道112畅通，在送风机14的作用下，即可进行CO 2的脱附，进而保证浊气吸附与释放单元15的重复循环利用。
执行步骤S4的条件包括：检测到的CO 2浓度在设定时间段内不再降低时，例如，CO 2检测模块检测的数值处于某一个固定范围不降低，且持续设定时间，例如10min，说明浊气吸附与释放单元15已经达到饱和状态，此时，空调器自动进行脱附工作，当然，也可以对此时的CO 2模块检测到的数值以及持续时间等信息进行显示或者播报，例如，通过空调显示面板、用户终端等反馈给用户，此时，若接收到用户发来的执行脱附工作指令时，则开始执行步骤S4。
其中，如图5所示，本发明的用于空调器的空气清洁控制方法的步骤S3还具体包括如下步骤：
步骤S31：控制CO 2检测模块检测环境中的CO 2浓度。
步骤S32：根据检测到的环境中的CO 2浓度，以及检测到的室内人数，控制送风机选择不同的转速。
当C≤C1时，并且当检测到的室内人数为＜3人时，送风机14停止运行；当检测到的室内人数为＝3人时，送风机14第一转速运行；当检测到的室内人数为＝4人时，送风机14第二转速运行；当检测到的室内人数＞4人时，送风机14第三转速运行。
当C1＜C≤C2时，并且当检测到的室内人数为＝1人时，送风机14停止运行；当检测到的室内人数为＝2人时，送风机14第一转速运行；当检测到的室内人数为＝3人时，送风机14第二转速运行；当检测到的室内人数＞3人时，送风机14第三转速运行。
当C2＜C≤C3时，并且当检测到的室内人数为＝1人时，送风机14第一转速运行；当检测到的室内人数为＝2人时，送风机14第二转速运行；当检测到的室内人数＞2人时，送风机14第三转速运行。
当C＞C3时，并且当检测到的室内人数为＝1人时，送风机14第二转速运行；并且当检测到的室内人数为≥1人时，送风机14第三转速运行。
其中，C为环境中的CO 2浓度，C1、C2、C3为预设的CO 2浓度，第一转速＜第二转速＜第三转速。
本发明将CO 2检测模块的检测结果划分为4档，以leve1(C≤C1)、leve2(C1＜C≤C2)、level3(C2＜C≤C3)、level4(C＞C3)进行说明，作为一种优选的实施方式，C1＝450，C2＝1000，C3＝2000，即如表1所示。
表1
Figure PCTCN2022078924-appb-000001
当检测结果为leve1时，此时室内空气质量为优，因此，若此时室内人数小于3人时，则关闭送风机14，不进行除CO 2工作，以节约电能以及避免噪音的产生，若室内人数为3人，随着时间的延长，室内的CO 2的浓度会稍有增加，但不会使室内空气质量很快变差，因此，送风机14按照第一转速运行，即按照低档位运行，以达到吸收CO 2的速率能够匹配CO 2浓度增加的速率的效果，进而继续保持室内环境质量为优；同理，当室内人数＝4人时，送风机14按照第二转速运行，即按照中档位运行，当室内人数＞4人时，送风机14按照第三转速运行，即按照高档位运行；总之，风机转速越高，吸附CO 2的速率就越高，因此，通过室内人数的增加，相应的提高送风机14转速，进而能够保持室内空气质量为优的状态的同时，尽可能的节约电能以及降低噪音。
当检测结果为leve2时，此时室内空气质量为良，因此，若此时室内人数为1人时，则关闭送风机14，不进行除CO 2工作，以节约电能以及避免噪音的产生，若室内人数为2人，随着时间的延长，室内的空气质量会稍微变差，因此，送风机14按照第一转速运行，即按照低档位运行，以达到吸收CO 2的速率能够匹配CO 2浓度增加的速率的效果，进而保持室内环境质量的优良状态；同理，当室内人数＝3人时，送风机14按照第二转速运行，即按照中档位运行，当室内人数＞3人时，送风机14按照第三转速运行，即按照高档位运行；通过室内人数的增加，相应的提高送风机14转速，进而能够保持室内空气质量为优或良的状态的同时，尽可能的节约电能以及降低噪音。
当检测结果为leve3时，此时室内空气质量为差，因此，若此时室内人数为1人时，由于人数少，所以CO 2浓度增加的缓慢，因此，送风机14按照第一转速运行，即按照低档位运行，就能达到除CO 2的速率超过产生CO 2的速率，进而使室内空气的质量达到优良状态；若此时室内人数为2人时，送风机14按照第二转速运行，即按照中档位运行，当室内人数＞2人时，送风机14按照第三转速运行，即按照高档位运行，总之，通过室内人数的增加，相应的提高送风机14转速，使除CO 2的速率超过产生CO 2的速率，进而改变室内空气质量为差的状态，将其提升至优良状态。
当检测结果为leve4时，此时室内空气质量极差，因此，若此时室内人数为1人时，送风机14按照第二转速运行，即按照中档位运行，当室内人数≥1人时，送风机14按照第三转速运行，即按照高档位运行，由于此时室内空气质量极差，因此，应提高送风机14转速，以达到更快的除CO 2的速率，并且，除CO 2的速率大大超过产生CO 2的速率，进而尽快改变室内空气质量为极差的状态，将其提升至优良状态。
总之，本发明的空调器的空气清洁控制方法根据室内人数能够匹配最优的风机转速，以达到在保持室内空气质量优良的同时，还能够最大限度的节约电能，以及减少噪音的产生。
本发明步骤S4的优选技术方案：由于浊气吸附与释放单元15具体包括固态胺吸附块和加热模块，通过控制加热模块对固态胺吸附块进行加热，以释放固态胺所吸附的CO 2。
吸附材料固态胺吸附块吸附CO 2的量和材料的体积有关系，当到达一定程度后，会达到饱和状态，当固态胺吸附块达到饱和状态后，控制加热模块进行加热，以实现CO 2的脱附，通常情况下，脱附温度在50-80℃之间，在此范围内温度越高脱附速率越快，因此，可以通过控制加热模块的温度，来达到控制CO 2的脱附速率的目的。
如图6所示，具体地，本发明的步骤S4的上述优选技术方案还具体包括如下步骤：
步骤S41:控制CO 2检测模块检测环境中的CO 2浓度。
步骤S42：根据检测到的环境中的CO 2浓度，控制送风机14选择不同的转速，并且控制加热模块选择不同的加热温度以及脱附时间。
步骤S421：当C≤C1时，送风机14第一转速运行，加热温度为T1，脱附时间为t1。
步骤S422：当C1＜C≤C2时，送风机14第一转速运行，加热温度为T2，脱附时间为t2。
步骤S423：当C2＜C≤C3时，送风机14第三转速运行，加热温度为T1，脱附时间为t3。
步骤S424：当C＞C3时，送风机14第三转速运行，加热温度为T2，脱附时间为t4。
其中，C为环境中的CO 2浓度，C1、C2、C3为预设的CO 2浓度，T1＜T2，t1＞t2＞t3＞t4，第一转速＜第三转速。
本发明将CO 2检测模块的检测结果划分为4档，以leve1(C≤C1)、leve2(C1＜C≤C2)、level3(C2＜C≤C3)、level4(C＞C3)进行说明，作为一种优选的实施方式，C1＝450，C2＝1000，C3＝2000，即如表1所示：
当检测结果为leve1时，对应的控制方式选择模式一；当检测结果为leve2时，对应的控制方式选择模式二；当检测结果为leve3时，对应的控制方式选择模式三；当检测结果为leve4时，对应的控制方式选择模式四；作为一种优选的实施方式，T1＝50℃，T2＝80℃，t1＝20min，t2＝17.5min，t3＝15min，t4＝10min，即如表2所示：
表2
Figure PCTCN2022078924-appb-000002
综合表1和表2可以看出，当室内环境中的CO 2浓度很低时，如leve1，此时，选择模式一，即将送风机14转速调低(第一转速)，加热温度调低(T1)，脱附时间最长(t1)，由于CO 2浓度较低，因此，本发明的控制方法对CO 2进行慢脱附，即延长CO 2脱附时间，主要目的是为了达到能耗低和噪音低的效果，以节约电能和提高用户体验度，同时还能够对室内空气环境进一步地进行优化；当室内环境中的CO 2浓度较低时，如leve2，此时，选择模式二，即将送风机14转速调低(第一转速)，加热温度调高(T2)，脱附时间较长(t2)，此时，能够达到能耗较低和噪音低的效果，此外，脱附效率相较于模式一有所提高；当室内环境中的CO 2浓度较高时，如leve3，此时，选择模式三，即将送风机14转速调高(第三转速)，加热温度调低(T1)，脱附时间较短(t3)，此时，能够达到脱附效率较高的效果，以便较快 的进行除CO 2工作，且此时能耗并未达到最高；当室内环境中的CO 2浓度很高时，如leve4，此时选择模式四，将送风机14转速调高(第三转速)，加热温度调高(T2)，脱附时间最短(t4)，从而达到最高的脱附效率，以便尽快的进行CO 2的吸附，总之，本发明的空调器根据当前环境中的CO 2浓度，选择最优的脱附效率、能耗和噪音的组合方式，在保证室内环境质量的前提下，能够达到最佳的综合使用效果。
需要说明的是，本领域技术人员在联想到CO 2与脱附时间的关系时，常规的控制方法是CO 2浓度越低，清洁时间就越短，然而本发明的发明构思恰恰相反，本发明从噪音和节能角度出发，CO 2浓度越低，清洁时间反而拉长，在逆向思维过程当中寻求到了更适宜用户舒适性的方案。
当不需要进行CO 2的吸附工作时，例如，当检测到的CO 2浓度＜预设浓度值时，如，达到leve1和leve2的优良等级时，或者当CO 2的吸附工作经过了预设的时间时，则自动关闭送风机14，并对环境中的CO 2浓度进行检测，将检测到的CO 2浓度信息转化为环境等级信息展示给用户，或者，同时将CO 2浓度信息以及CO 2的吸附工作运行时间信息展示给用户。
作为浊气吸附与释放单元15的另一种优选实施方式，浊气吸附与释放单元15具体包括高压静电吸附板，则本发明的用于空调器的空气清洁控制方法包括：
开启进气阀12、关闭排气阀13，然后开启送风机14，并启动高压静电吸附板。开启排气阀13、关闭进气阀12，并关闭高压静电吸附板，控制送风机14对高压静电吸附板进行吹气，以释放高压静电吸附板所吸附的尘土。
当需要对室内进行除尘时，开启进气阀12、关闭排气阀13，并在送风机14的作用下，将室内的污浊空气引入进气通道111内，此时，在高压静电吸附板的作用下，能够将室内的尘土进行吸附，在高压静电吸附板上的尘土达到饱和时，或者为了达到更好的尘土吸附效率时，关闭高压静电吸附板，通过送风机14将高压静电吸附板上的尘土由排气通道112吹向室外，以释放高压静电吸附板所吸附的尘土。
此外，本发明还提供了一种空调器，该空调器为上述技术方案中任一项的空调器，并且包括控制器，控制器设置成能够执行上述任一项技术方案中所述的用于空调器的空气清洁控制方法。
综上所述，本发明的空调器通过浊气吸附与释放单元15能够将污浊空气进行净化，并通过加热模块对固态胺吸附块进行加热，以使浊气进行释放，其中，随着加热温度的升高，浊气的脱附效率随之增加，此外，本发明的排气管的直径较细，能够与空调器的联机管共用一个孔洞，降低安装成本，此外，当检测到的室内CO 2浓度较低时，脱附时间反而较长，能够达到降噪以及降低能耗的效果，此外，通过人数检测模块检测室内人数，并根据室内人数以及室内浓度选择相应的送风机14转速，以保持室内的空气质量始终为优良的状态。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
本领域技术人员可以理解，上述空调器还包括一些其他公知结构，例如处理器、控制器、存储器等，其中，存储器包括但不限于随机存储器、闪存、只读存储器、可编程只读存储器、易失性存储器、非易失性存储器、串行存储器、并行存储器或寄存器等，处理器包括但不限于CPLD/FPGC、DSP、CRM处理器、MIPS处理器等。为了不必要地模糊本公开的实施例，这些公知的结构未在附图中示出。
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。
