- the second temperature of the gas detected by the second temperature sensor is acquired, and the second temperature is within 10-15s ( If the temperature rise is not lower than 5°C within 10s), cut off the power supply of the heating tube.
- the control method of the present invention also makes such a supplementary limitation: the first/second temperature detected by the first/second temperature sensor is greater than or equal to 65-90°C (E.g. 70°C), regardless of whether the first/second temperature meets the aforementioned conditions for cutting off the power supply of the heating tube, the power supply of the heating tube is directly forcibly cut off.
- 65-90°C E.g. 70°C
- the pulsator washing machine After using any one of the above three logics to cut off the power of the heating tube, the pulsator washing machine is still working under the premise that the basic functions of the pulsator washing machine are as little affected as possible, the control method of the present invention Also make such additional qualifications:
- the liquid level sensor After 3-5 minutes, re-check the temperature in the first chamber. If the liquid level sensor has detected the liquid level and the first temperature has dropped to a level not higher than 40-60°C (such as 50°C), you can reconnect Turn on the power supply of the heating tube. In this case, the main reason for the excessively rapid temperature rise is that the heating tube is overheated, and the amount of water flowing through the heating pump is large and the circulation is normal. The reason for the large amount of water may be related to the opening size of the bottom of the inner tub corresponding to the inner circulation unit and the operating parameters of the motor of the heat pump.
- the liquid level sensor After 3-5 minutes, re-detect the temperature in the first chamber. If the liquid level sensor still detects the liquid level and the second temperature has dropped to a level not higher than 45-65°C (such as 50°C), you can reconnect Turn on the power supply of the heating tube. In this case, the main reason for the excessive temperature rise is that the heating pipe is overheated, and the amount of water flowing through the heat pump is small but the flow is normal. Similar to the amount of water, the reason for the small amount of water may be the size of the opening at the bottom of the inner barrel corresponding to the internal circulation unit. And related to the operating parameters of the motor of the heat pump.
- the supplementary limit for re-testing can also adopt such an alternative method. You don’t need to wait for 3-5 minutes to test again.
- the first temperature/second temperature will be detected immediately after the power is turned off. For example, the first temperature decreases by no less than 10 within 30s. In the case of -20°C (such as 10°C), or in the case where the second temperature has dropped by no less than 5-20°C (such as 5°C) within 20s, reconnect the power to the heating tube. This shows that after the power supply of the heating tube is cut off, with the smooth water flow, the heat is dispersed in time, so the main reason for the excessive temperature rise is the overheating of the heating tube.

目前的加热泵通常是这样的结构:主要实现加热的部分与主要实现排水的部分集中设置,即位于一个腔室,这样一来,需要的加热功能越强,则需要为加热部分配置更大的体积,腔室的体积随之增大,而腔室越大,则需要配置更大功率的电机,这会造成不必要的能源的浪费。
相应地,本领域需要一种新的技术方案来解决上述问题。

本发明一方面提供了一种衣物处理设备的控制方法,所述衣物处理设备包括内循环单元,所述内循环单元包括加热泵,加热泵包括 泵主体,所述泵主体具有第一腔室和第二腔室,所述泵主体在对应于所述第一腔室的位置设置有进水口且所述第一腔室配置有加热构件,所述泵主体在对应于所述第二腔室的位置设置有排水口且所述第二腔室配置有动力部,以便在所述动力部的作用下,水能够依次经所述进水口、所述第一腔室、所述第二腔室以及所述排水口排出,其中,所述加热泵还包括连接构件,所述连接构件上设置有至少一个连通结构,所述第一腔室和所述第二腔室借助于所述连通结构彼此连通,所述方法包括:检测所述第一腔室内的温度;至少在所述温度在设定期间的升高量大于等于设定阈值的情形下,使所述加热构件的加热功能中断。
通过将主要用于实现加热的第一腔室与主要用于排水的第二腔室分开,便可以依据所需的扬程及流量进行单独调整第二腔室的容积,从而能够谋求有效地降低动力部的功率,进而实现节约成本的目的。
可以理解的是,与单独调整第二腔室的容积类似,同样也可以根据实际情形单独地调整第一腔室的容积。并且,由于第一腔室主要用于加热,而加热构件通常是一个持续处于静止状态的部件,因此与第一腔室不同的是,第二腔室的结构与容积均不会受如动力部的限制,因此,除了可以调整容积,还可以根据实际情况调整结构等其他规格,如可以为棱柱状的筒、由多段棱柱状组成的筒、筒的其中的全部或者一部分为不规则结构、筒的一部分为实心结构等。
连接构件的主要作用是将两个腔室连接并连通,在能够满足该功能的条件下,本领域技术人员可以根据实际情况灵活选择连接构件的具体形式。如连接构件为一个单独的构件,或者与泵主体对应于第一腔室和/或第二腔室的结构为一体成型等。示例性地,如连接构件为一个单独的具有多个孔的结构,连接构件的外表面向外延伸有翻边,翻边与泵主体借助于紧固件(如螺栓)固接,连接构件在对应于第一腔室的位置加装有过滤网。
通过这样的设置,可以在加热构件自身的加热功能或者与第一腔室内的温度相关联的部件或者控制逻辑出现异常的情形下,能够通过阻断加热的方式避免由此导致的加热构件、加热泵、衣物处理设备被损坏的现象。
需要说明的是,由于第一腔室内的温度出现异常的情形可能并不仅仅是加热构件自身的故障导致的,还可能是加热泵的其他结构导致的,如在进水口堵塞或者电机转速过快的情形下,进入第一腔室内的内桶的水的量变小,在热量供给一定的情形下,会导致水温持续过高的现象。还可能是内循环单元或者衣物处理设备的其他结构或者功能导致的。
不过,无论是由于何种原因,将加热及时阻断的方式必然能直接地降低由于温升过快导致的损失。因此,本发明中阻断加热时机的确定并不仅仅是参考内桶中的洗涤水的温度、第一腔室内的理论温度等单一的参数确定,而是有一个过程中的温度变化,暂称为温升率来判断。
对于上述控制方法,在一种可能的实施方式中,所述第一腔室内设置有第一温度传感器和液位传感器,所述的“检测所述第一腔室内的温度”进一步包括:在所述液位传感器能检测出所述第一腔室内的水的液位的情形下,获取通过所述第一温度传感器检测的水的第一温度。
通过这样的设置,旨在谋求能够初步确定出温升异常的现象与第一腔室内的水流的关联较小的情形下,通过检测第一腔室内的液体温度的方式来判断加热构件的异常状态。
可以理解的是,液位传感器的设置方位应当满足:在进水排水以及循环顺畅的情形下,能检测到第一腔室内的水位。也就是说,通过增加液位传感器的检测要素,能够确定阻断加热的时机时除了考虑加热构件本身的因素还可以综合考虑其他的因素,从而能够谋求获得考虑更全面的控制逻辑。
对于上述控制方法,在一种可能的实施方式中,所述第一腔室内设置有第二温度传感器和液位传感器,所述的“检测所述第一腔室内的温度”进一步包括:在所述液位传感器未能检测出所述第一腔室内的水的液位的情形下,获取通过所述第二温度传感器检测的气体的第二温度。
通过这样的设置,旨在谋求能够初步确定出温升异常的现象与第一腔室内的水流的关联较大的情形下,通过检测第一腔室内的气液混合物的温度的方式来判断加热构件的异常状态。
可以理解的是,通常情形下,对应于的液体温度的温升率应当低于对应于水汽的温升率,这是因为:在液位传感器未能检测出第一腔室内的水的液位的情形下,温升异常与水流的关联较大,此时的温升更明显,并且水汽和水蒸气的气液混合物要比单独的热水的温度更高。
对于上述控制方法,在一种可能的实施方式中,所述第一温度传感器与所述第二温度传感器合一设置且配置为能够改变其在所述第一腔室内的高度位置。
通过这样的设置,根据液位传感器的检测结果,只要初步确定了温升异常与水流之间的关联程度,即可通过合一设置的传感器在不同的高度位置来采集第一腔室内的温度,从而根据温度来确定是否需要阻断加热。
可以理解的是,此处的高度位置的改变,可以通过仅在高度这一个方向上的位置改变来实现。不过,结合本发明的方案,在能够实现温度传感器检测不同高度位置的温度的前提下,显然不应当局限地理解为仅高度位置的改变。
如可以是:结合加热泵的已有结构,在实现高度位置改变的同时,也可以伴随有其他方位的改变,只要这样的改变仍然能够保证温度传感器能够采集到期望的气体或者液体的温度即可。
也可以是:为加热泵增加允许高度位置改变的结构,同时,这样的结构在增加至加热泵的过程中,可以是只包括高度位置的改变,也可以同时伴随有其他方位的改变。如:在将这样的结构增加至加热泵的过程中,在部件的布局上与将加热泵安装至衣物处理设备的安装结构存在一定的干涉,因此,最终在实现高度位置改变的前提下,还伴随着温度传感器的倾斜等。
对于上述控制方法,在一种可能的实施方式中,所述泵主体形成有容纳空间,合一设置的所述第一温度传感器和所述第二传感器配置有切换机构,其中,所述合一设置的第一温度传感器和第二传感器能够通过所述切换机构其相对于所述容纳空间的位置。
通过这样的设置,能够结合液位传感器的检测结果来改变温度传感器的高度位置,从而能够根据检测的温度确定出是否需要阻断加热构件的加热。切换机构可以采用任意已知的可实现伸缩、升降等功能 的结构来实现,本领域技术人员可以根据实际情形灵活性选择切换机构的具体形式及其在加热泵上的设置位置以及安装方式等,在此不作具体限定。
对于上述控制方法,在一种可能的实施方式中,所述第一温度传感器和所述第二温度传感器分体设置,其中,所述第一温度传感器的探头位置低于所述第二温度传感器的探头位置。
通过这样的设置,可以谋求通过两个独立的温度传感器来实现不同情形的测温需求。可以理解的是,两个温度传感器的规格、安装方式等可以相同或者不同。
对于上述控制方法,在一种可能的实施方式中,所述泵主体在靠近所述第一腔室的顶部的位置开设有孔,所述进水口处配置有进水管,所述第一腔室配置有连接管,所述连接管的第一端与所述孔相连接,所述连接管的第二端与所述进水管连通,其中,所述第二温度传感器设置于所述泵主体对应于所述第一腔室且靠近所述孔的位置。
通过连接管的设置,避免了在进水过程中在第一腔室内可能出现的存空气的现象,从而保证了第一腔室内能够充满水。
通过将第二温度传感器与连接管之间进行这样的搭配设置,可以谋求第二温度传感器能够在液位传感器检测不到水位的情形下,保证较高位置的第二温度传感器检测到第一腔室内的水汽的温度。此外,增设连接管的位置可以为第二温度传感器预留更多的安装空间。如可以是第二温度传感器包括主体和探头,主体的一部分在安装好的状态下容纳于连接管内。
对于上述控制方法,在一种可能的实施方式中,所述的“至少在所述温度在设定期间的升高量大于等于设定阈值的情形下,使所述加热构件的加热功能中断”进一步包括:所述温度大于极限阈值的情形下,无论所述温度在设定期间的升高量大于等于设定阈值,使所述加热构件的加热功能中断。
通过这样的设置,能够谋求更好地通过阻断加热的方式保证加热泵的可靠性。
对于上述控制方法,在一种可能的实施方式中,在“使所述加热构件的加热功能中断”的步骤,所述方法还包括:检测所述第一腔 室内的温度;根据所述温度的降低程度,判断是否恢复所述加热构件的加热功能。
通过这样的设置,能够谋求尽量低程度地由于加热构件影响衣物处理设备的基本功能。
本发明另一方面还提供了一种衣物处理设备,该衣物处理设备包括控制器,所述控制器用于执行前述任一项所述的衣物处理设备的控制方法。
需要说明的是,该衣物处理设备具有前述的衣物处理设备的控制方法的所有技术效果,在此不再赘述。

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。虽然本实施例是以波轮洗衣机为例来进行阐述的,但是还可以适用于其他形式的衣物处理设备,如子母机、洗干一体机等。
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”等指示的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”仅用于描述目的,而不能理解为指示或暗示相对重要性。

参照图1,图1示出本发明一种实施例的波轮洗衣机的结构示意图。如图1所示,波轮洗衣机100主要包括箱体1、设置于箱体上方的盘座、固定设置于箱体内部的外桶2以及可旋转地设置于外桶内部的内桶组 件,箱体主要包括箱主体以及设置于箱主体底部的底台,底台的下表面设置有多个支撑脚11(如底台的四个边角处设置有4个支撑脚),波轮洗衣机通过4个支撑脚11放置在如洗手间的地面等位置。波轮洗衣机配置有排水管,通过将排水管与所放置的位置的地漏连接,即可将洗涤水及时地排出。外桶的上方设置有外桶盖,外桶盖上具有衣物投放口,盘座上在对应于衣物投放口的位置枢转设置有盖体,以便通过打开盖体的方式将衣物经衣物投放口放入内桶或者从内桶中取出。内桶组件包括内桶3以及设置于内桶上方的平衡环,平衡环为中空结构且内容填充有如盐水等介质以便促进内桶在旋转过程中的稳定性。内桶的底部设置有波轮4,波轮配置有作为动力部的动力传动机构,动力传动机构如可以包括电机51和减速器52,电机的动力输出轴与减速器的动力输入轴相连接,减速器的动力输出轴与波轮相连接。外桶和箱体之间还设置有作为减振部件的吊杆6,具体地,吊杆的下端与外桶靠近底部的位置相连接,吊杆的上端与箱体靠近顶部的位置相连接。
在洗涤阶段和漂洗阶段,洗涤水通过进水管道进入波轮洗衣机的内桶后,在波轮洗衣机内的流通方式通过两种方式来实现:其中一个是:在内桶的桶壁上设置有通孔,从而使洗涤水能够在外桶和内桶之间流通。另一个是:在波轮洗衣机内增加内循环单元,具体地:波轮洗衣机的底部内侧配置有泵,泵的进水口与内桶底部的孔连通,泵的排水口和内循环管路7的进水端相连接,内循环管路的出水端能够将洗涤水从内桶的上部重新送入内桶。也就是说,在泵的作用下,内桶中的水从底部被抽至内循环管路之后经顶部重新进入,如在内循环管路的出水端配置喷头71,从而使从内循环管路中出来的水以喷洒的方式重新进入内桶。在本发明中,排水泵为具有加热功能的加热泵8。
参照图2,图2示出本发明一种实施例的波轮洗衣机的加热泵的结构示意图。如图2所示,加热泵8包括泵主体81,泵主体具有第一腔室811和第二腔室812,第一腔室和第二腔室之间通过隔板82隔开且二者通过设置于隔板上的连接构件83实现二者的连通,泵主体在对应于第一腔室的位置设置有进水口,进水口处配置有进水管813,第一腔室内配置有加热构件,进水管与内桶的底部相连,以便内桶的洗涤水经进水管进入第一腔室内被加热。泵主体在对应于第二腔室的位置设置有第一排水 口,第一排水口处配置有第一排水管814,第一排水管与内循环管路相连,以便洗涤水在第一腔室内被加热之后经第二腔室送入内循环管路。泵主体在对应于第一腔室的位置在靠近底部(如接近最低点)的位置还设置有第二排水口,第二排水口处配置有第二排水管815,第二排水管主要用于将第一内的液体排干净以及将残留在第一内的污渍等杂质排出加热泵。
参照图3,图3示出本发明一种实施例的波轮洗衣机的加热泵中连接管的结构示意图。如图3所示,为了保证第一腔室内能够充满水,在第一腔室的顶部和进水管的管壁之间增设有一根较细的连接管816,具体地,连接管包括主体管段8160以及分别设置于主体管段的两端的第一连接管段8161和第二连接管段8162,第一连接管段与泵主体1对应于第一腔室的顶部的位置开设的孔连通,第二连接管段与进水管813的管壁连通。
在一种具体的实施方式中,主体管段包括依次连接的第一子管段、第二子管段和第三子管段,其中,第二子管段比(第一、第三)子管段长,(第一、第三)子管段主要起过渡作用,示例性地(第一、第二)子管段之间形成钝角,(第二、第三)子管段之间大致垂直。为了保证更平滑的连接效果,在(第一、第二)子管段之间以及(第二、第三)子管段之间增加弧形连接段。
在基于本发明的结构的控制方法中,是以第一温度传感器8111和第二温度传感器分体设置的方式来进行描述的。其中,第一温度传感器用于第一腔室内的液位正常时能够检测到液体的温度,而第二温度传感器则用于在第一腔室内的液位不正常(即配置的液位传感器检测不到液位时检测第一腔室内水汽的温度)在一种具体的实施方式中,第一温度传感器811距离加热构件10mm左右且位于加热构件的下游侧(即图3中的右侧),这样一来,在加热泵运行期间,第一温度传感器能够更实时地感知流动水的温度。第二温度传感器和液位传感器均未示出。
参照图4,图4示出本发明一种实施例的波轮洗衣机的加热泵中连接构件的结构示意图。如图4所示,在隔板的中部开设有孔,连接构件为筒状结构,筒状结构的左端为开放结构且与隔板位于孔的外缘的部分一体成型,筒状结构的右端为封闭结构831,筒状结构的筒壁上设置有 连通结构,第一腔室和第二腔室借助于连通结构彼此连通。连接构件的功能包括两个:一个是保证两个腔室之间的连通,一个是对进入第一腔室内的洗涤水进行扰流以获得更充分的加热效果。
为了更好地实现扰流作用,对筒状结构作这样的改进:将筒状结构的筒壁设置为自左向右外径逐渐增加的结构,将右端的封闭结构设置为中部较外缘向右凸出的结构。
为了保证第二腔室内能够充满水,在隔板82对应于中部的孔的上方和下方分别设置有一个孔径大约为5mm左右的连通孔821。具体地,两个连通孔均设置于与泵主体对应于第二子腔室的内壁相内切的位置,即靠近外侧的位置。可以理解的是,孔的尺寸以及设置位置均可以根据实际情况灵活调整。
在本实施例中,筒状结构的筒壁包括沿周向分布的若干支撑筋832,相邻的支撑筋与左端的隔板以及右端的封闭结构之间即形成大致为方形的连通结构。显然,本领域技术人员可以根据实际情况灵活地调整连通结构的具体形式,如筒壁上直接打孔等。
参照图5,图5示出本发明一种实施例的波轮洗衣机的加热泵中叶轮组件的结构示意图。如图5所示,第二腔室配置有动力部,如动力部包括驱动构件841(如电机)和叶轮组件842,作为驱动构件的电机的动力与叶轮组件相连接,叶轮组件的叶轮自由容纳于第二腔室,以便通过电机带动叶轮在第二腔室内旋转,从而将水从第一腔室抽至第二腔室并经第一排水口排出。也就是说,在电机的作用下,内桶底部的洗涤水能够依次经进水口、第一腔室、第二腔室、第一排水口、循环管路从内桶顶部重新进入内桶。在一种可能的实施方式中,第二腔室812包括彼此连通的第一子腔室8121和第二子腔室8122,第一子腔室的径向尺寸大于等于第二子腔室的径向尺寸,叶轮组件的基体8421安装在第一子腔室8121内,叶轮组件的叶轮8422自由容纳于第二子腔室8122。
加热构件包括电源部分851和加热部分,加热部分为容纳于第一腔室内的加热管852,以便通过浸设于第一腔室内的方式对水进行加热,与加热管电气连接的电源部分设置于第一腔室外并位于靠近底部的位置。为了防止加热管由于过热导致水温过高或者加热构件被损坏,可以为加热管配置熔断器。
参照图6,图6示出本发明一种实施例的波轮洗衣机的加热泵中安装结构的结构示意图。如图6所示,泵主体1的外表面配置有安装结构,安装结构包括支架9,支架包括第一子支架91和第二子支架92,第一子支架和第二子支架通过连接架93连接,第一子支架设置于泵主体对应于第一腔室的位置,第二子支架设置于泵主体对应于第二腔室的第一子腔室的位置,连接架为沿第二腔室的第二子腔室的轴向分布的板状结构。其中,第一子支架上设置有两个安装孔,第二子支架上设置有一个安装孔,三个安装孔94大致围设成一个三角形的安装位,加热泵8通过三点固定的方式稳定地固定于波轮洗衣机内。
可以看出,在本发明的波轮洗衣机中,通过将主要用于实现加热功能的第一腔室与用于实现排水功能的第二腔室分开,两个腔室可以分别针对各自的实际情形进行调节。尤其对于第二腔室而言,由于其容积可以依据波轮洗衣机所需的扬程及流量进行单独调整,从而能够谋求有效地降低动力部的功率,实现了节约成本的目的。
基于上述结构,波轮洗衣机还包括控制器,控制器(包括控制模块)用于执行如下的波轮洗衣机的控制方法。
参照图7,图7示出本发明一种实施例的波轮洗衣机的控制方法的逻辑示意图。如图7所示,波轮洗衣机的控制方法包括如下步骤:
检测所述第一腔室内的温度;至少在温度在设定期间的升高量大于等于设定阈值的情形下,切断加热管的电源从而使加热管的加热功能中断。具体地:
如在高度为1/4、1/2、3/4个第一腔室的直径的位置分别设置三个液位传感器,对应的是第一腔室内的低液位、中液位和高液位,在对应于高液位的液位传感器能够检测出第一腔室内的水的液位的情形下,获取通过第一温度传感器检测的水的第一温度,在第一温度在10-30s(如20s)内升高了不低于5℃的情形下,切断加热管的电源。在对应于高液位的液位传感器未能检测出第一腔室内的水的液位的情形下,获取通过第二温度传感器检测的气体的第二温度,在第二温度在10-15s(如10s)内升高了不低于5℃的情形下,切断加热管的电源。
在此前提下,为了更好地保护装置不被损坏,本发明的控制方法还作这样的补充限定:在第一/第二温度传感器检测到的第一/第二温度大于等于65-90℃(如70℃)的情形下,无论第一/第二温度是否满足前述的切断加热管的电源的条件,都直接强行切断加热管的电源。
在采用了以上三种逻辑任一种执行了切断加热管的电源动作之后,在波轮洗衣机仍然工作的前提下,为了保证波轮洗衣机的基本功能尽可能少地受影响,本发明的控制方法还作这样的补充限定:
在3-5min之后,重新检测第一腔室内的温度,若液位传感器已经检测到液位且第一温度已经降至不高于40-60℃(如50℃)的水平,则可以重新接通加热管的电源。这种情形下,温升过快的原因主要是加热管过热,流经加热泵的水量较多且流通正常。水量多的原因可能与内循环单元对应的内桶底部的开口尺寸以及加热泵的电机的运转参数等相关。
在3-5min之后,重新检测第一腔室内的温度,若液位传感器仍检测到液位且第二温度已经降至不高于45-65℃(如50℃)的水平,则可以重新接通加热管的电源。这种情形下,温升过快的原因主要是加热管过热,流经加热泵的水量较少但流通正常,与水量多类似,水量少的原因可能与内循环单元对应的内桶底部的开口尺寸以及加热泵的电机的运转参数等相关。
重新检测的补充限定也可以采用这样的替代方式,不用等待3-5min之后再检测,在切断电源之后马上开始检测第一温度/第二温度,如第一温度在30s内降低了不低于10-20℃(如10℃)的情形下,或者在第二温度在20s内降低了不低于5-20℃(如5℃)的情形下,重新接通加热管的电源。这表明在切断加热管的电源之后,随着顺畅的水流流通,热量得到了及时的分散,因此温升过快的原因主要是加热管过热。
如果不满足上述重新接通加热管的电源的条件,则说明本次的温升过快的问题不仅仅与加热管过热有关,则需要结合其他问题进行进一步排查,在此不作讨论。
显然,上述示例中涉及的数据只是发明人在实验和分析得出的示例性数值或者说较优选的数值。显然,本领域技术人员可以根据实 际情况灵活地调整对应于温升率的时间和温升量等,以便更好地确定出阻断或者恢复加热构件的加热功能的时机。
需要指出的是,尽管上述控制方法中将各个步骤按照特定的先后顺序进行了描述,但是本领域技术人员可以理解,为了实现本发明的效果,不同的步骤之间并非必须按照这样的顺序执行,其可以同时(并行)执行或以其他顺序执行,这些变化都在本发明的保护范围之内。
本领域技术人员能够理解的是,本发明实现上述一实施例的方法中的全部或部分流程,也可以通过计算机程序来指令相关的硬件来完成,所述的计算机程序可存储于一计算机可读存储介质中,该计算机程序在被处理器执行时,可实现上述各个方法实施例的步骤。其中,所述计算机程序包括计算机程序代码,所述计算机程序代码可以为源代码形式、对象代码形式、可执行文件或某些中间形式等。所述计算机可读介质可以包括:能够携带所述计算机程序代码的任何实体或装置、介质、U盘、移动硬盘、磁碟、光盘、计算机存储器、只读存储器、随机存取存储器、电载波信号、电信信号以及软件分发介质等。需要说明的是,所述计算机可读介质包含的内容可以根据司法管辖区内立法和专利实践的要求进行适当的增减,例如在某些司法管辖区,根据立法和专利实践,计算机可读介质不包括电载波信号和电信信号。
进一步,应该理解的是,控制器对应的物理器件可以是处理器本身,或者处理器中软件的一部分,硬件的一部分,或者软件和硬件结合的一部分。
本领域技术人员能够理解的是,控制器中对应于不同的步骤的模块进行适应性地拆分或合并。对具体模块的这种拆分或合并并不会导致技术方案偏离本发明的原理,因此,拆分或合并之后的技术方案都将落入本发明的保护范围内。
需要说明的是,尽管以如上具体方式所构成的具体的加热泵应用于波轮洗衣机这一目标场景、并以第一温度传感器和第二温度传感器分体设置的方式作为示例介绍了本发明的控制方法,但本领域技术人员能够理解,本发明应不限于此。事实上,用户完全可根据以及实际应用场景等情形灵活地调整目标场景、加热泵上的具体部件的结构以及温度传感器的设置形式等。
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。
