Description

家用水机的制冷控制方法及装置 技术领域
本发明涉及电器技术领域，特别涉及一种家用水机的制冷控制方法和一种家用水机的制冷控制装置。
背景技术
对于饮水设备行业而言，由于其行业成本因素的限制，相关饮水设备的制冷能力一般设计在2升左右，若再提高制冷能力，饮水设备所需的成本会大幅增加，从而失去了价格竞争力。
相关技术主要存在的以下缺点：
其一是，相关饮水设备的冷凝器不能满足超低水温的性能要求。这是由于冷凝器升高到一定温度后，饮水设备中的蒸发温度将不再变化，饮水设备中制冷装置失去了调节能力，从而导致饮水设备中长时间的超负荷运行。如果将冷凝器更换为制冷能力更强的冷凝器，虽然能够改善上述情况，但会大幅增加成本。此外，由于饮水机的尺寸都非常小，导致对冷凝器尺寸也有限制。
其二是，相关饮水设备的压缩机不能满足超低水温的性能要求。这是由于如果要达到超低水的温度的性能要求，那么饮水设备中的蒸发温度也要设计的很低，压缩机排气量也需相应加大。如果将压缩机更换为排气量较大的压缩机，会导致产品成本增加。并且，为了与压缩机相匹配，相应的蒸发器也要做得非常大、毛细管做得非常长，这些都也会使得成本提高。
由此，通过增大压缩机的排气量、增大冷凝器和蒸发器尺寸以及增长毛细管等提升饮水设备的制冷能力，将会大幅提高生产成本，使得用户难以接受，降低产品的市场竞争力。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参考附图描述本发明实施例的家用水机的制冷控制方法及装置。
图1是根据本发明实施例的家用水机的制冷控制方法的流程图。家用水机用于对储水容器内的水进行降温，并在用户不用水时，将低温冷水储备起来，当用户用水时，可随时放出大量的低温冷水。
如图1所示，根据本发明实施例的家用水机的制冷控制方法包括以下步骤：
S1、接收制冷指令，并根据制冷指令进入制冷模式。
其中，在制冷模式下，家用水机进行制冷运行以对家用水机内的水进行降温。
S2、获取家用水机的运行参数。
根据本发明的一些实施例，运行参数可为冷凝器的温度、制冷时间、冷水温度、蒸发器温度和环境温度中的一个或多个。
S3、根据运行参数判断是否满足暂停条件。
S4、如果满足暂停条件，则暂停制冷。
S5、进一步判断是否满足重启条件，如果满足重启条件，则进行制冷并重复执行步骤S2-5，直至满足制冷结束条件。
也就是说，在不断循环执行步骤S2-5的过程中，如果家用水机内的水温下降到小于或等于预设的目标水温，则判断满足制冷结束条件，退出制冷模式，控制家用水机停止制冷。
家用水机开始进行制冷运行后，开始对储水容器内的水进行降温。随着制冷时间的加长，家用水机中冷凝器的散热可能会达到最大，蒸发温度无法继续下降，此时可判断出运行参数满足暂停条件，之后，可通过各种方式使得家用水机短暂停下来以暂停制冷，这样，冷凝器和压缩机的热量快速散向外界，整个家用水机又调整到最佳制冷状态，此时可判断出运行参数判断满足重启条件，家用水机重新进行制冷运行，继续将储水容器内的水温往下降。随着制冷时间的继续加长，家用水机中冷凝器的散热可能又会达到最大，蒸发温度也无法继续下降时，家用水机又会短暂停下来，冷凝器和压缩机的热量快速散向外界，家用水机又调整到最佳制冷状态，然后又重新进行制冷运行。
如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温，完成制冷。
也就是说，通过间歇式制冷控制方式，不断调整家用水机的散热状态，使整个家用水机长时间保持在高效率运转状态，直到水温降低到预设的目标水温。
本发明实施例提出的家用水机的制冷控制方法，在进入制冷模式之后，获取家用水机 的运行参数，并根据运行参数判断是否满足暂停条件，如果满足暂停条件，则暂停制冷，进一步判断是否满足重启条件，如果满足重启条件，则进行制冷并重复判断是否满足暂停条件和重启条件，直至满足制冷结束条件。由此，在家用水机的运行过程中，通过暂停制冷使冷凝器、蒸发器的性能重新恢复到最优性能状态，下一次运行时蒸发温度可以降得很低，从而使得冷凝器、蒸发器及压缩机的性能达到多倍的发挥，实现超低水温制冷，提高了制冷能力。并且，该方法还避免了成本增加，避免了冷凝器和蒸发器超负荷运行引起的性能不稳定的不足，提高了家用水机的稳定性。
下面结合以下具体实施例来详细描述本发明实施例的制冷控制方法。
根据本发明的一个具体实施例，运行参数可为家用水机中冷凝器的温度，其中，当冷凝器的温度大于第一预设温度阈值时判断满足暂停条件，并在冷凝器的温度小于第二预设温度阈值时判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如暂停时间是否达到时间阈值。
需要说明的是，可通过安装在冷凝器上的第一温度传感器检测冷凝器的温度。更具体地，第一温度传感器可安装在冷凝器的末端以检测冷凝器末端的温度。
家用水机进行制冷运行，冷水温度开始下降，并且冷凝器的温度开始上升，当冷凝器的温度达到第一预设温度阈值时，判断满足暂停条件，家用水机暂时停下来，然后冷凝器向空气中快速散热，冷凝器的温度快速下降，当冷凝器的温度下降到小于第一预设温度阈值时，判断满足重启条件，家用水机重新进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温。这样即可通过间歇式制冷控制方式完成制冷。
根据本发明的另一个具体实施例，运行参数可为家用水机的制冷时间，其中，当制冷时间大于第一预设时间阈值时判断满足暂停条件，并在暂停时间大于第二预设时间阈值时判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如冷凝器的温度是否小于预设温度阈值。
需要说明的是，可通过第一计时器对制冷时间进行计时以及可通过第二计时器对暂停时间进行计时。更具体地，当家用水机进入制冷模式时，可控制第一计时器从0开始进行计时以记录制冷时间；当家用水机暂停制冷时，可控制第二计时器从0开始进行计时以记录暂停时间。

需要说明的是，可通过第三计时器对暂停时间进行计时。更具体地，当家用水机暂停制冷时，可控制第三计时器从0开始进行计时以记录暂停时间。
家用水机开始进行制冷运行，水温向多个设定水温中的一个下降，当将常温水降到多个设定水温中的一个时，冷凝器的散热达到最大值，蒸发温度无法继续下降，家用水机短暂停止运转，然后冷凝器向空气中快速散热，当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，满足重启条件。然后，家用水机重新进行制冷运行，水温再向多个设定水温中的另一个下降，当将冷水温度下降到多个设定水温中的另一个时，冷凝器的散热达到最大值，家用水机短暂停止运转，当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，家用水机又进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温，这样即可通过间歇式制冷控制方式完成制冷。
另外，需要说明的是，多个设定水温可按降序排列，通过间歇制冷冷水温度可逐渐下降直至达到目标水温。举例来说，多个设定水温可包括水温1、水温2和水温3，其中，水温1大于水温2且水温2大于水温3，并且水温3为目标水温。这样，家用水机进行制冷运行后，冷水温度先向水温1下降，当冷水温度达到水温1时，家用水机暂时停下来。当暂停时间达到第三预设时间阈值时，家用水机重新进行制冷运行，冷水温度向水温2下降，当冷水温度达到水温2时，家用水机暂时停下来。当暂停时间达到第三预设时间阈值时，家用水机再次进行制冷运行，冷水温度向水温3下降，当冷水温度达到水温3时，冷水温度达到目标水温，停止制冷。

进一步地，在暂停时间大于第三预设时间阈值时判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如冷凝器的温度是否小于预设温度阈值。
需要说明的是，可通过第三计时器对暂停时间进行计时。更具体地，当家用水机暂停制冷时，可控制第三计时器从0开始进行计时以记录暂停时间。
家用水机开始进行制冷运行，冷水温度开始下降，并且冷凝器的温度开始上升，当冷凝器的温度与环境温度间之间的温度差小于第四预设温度阈值时，判断满足暂停条件，家用水机暂时停下来，然后冷凝器向空气中快速散热，冷凝器的温度快速下降。当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，满足重启条件，然后，家用水机重新进行制冷运行，冷水温度继续下降，并且冷凝器的温度继续上升，当冷凝器的温度与环境温度间之间的温度差小于第四预设温度阈值时，家用水机又暂时停止运转。当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，家用水机又进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得非常低，例如将水温降至预设的目标 水温，这样即可通过间歇式制冷控制方式完成制冷。
换言之，可使冷凝器温度和环境温度之间的温差始终保持在最大温差，以利于家用水机向空气散热，当冷凝器温度和环境温度之差小于第四预设温度阈值时，家用水机又短暂停止制冷运行，使冷凝器及压缩机的热量快速散向外界，在家用水机调整到最佳制冷状态时再启动制冷运行，如此不断的循环运行，直到冷水温度达到超低的目标水温。
此外，在本发明的其他实施例中，也可以把冷凝器的温度、制冷时间、冷水温度、蒸发器温度与冷水温度之差以及冷凝器温度和环境温度之差同时结合起来进行制冷控制，通过交错使用上述判断条件，获得最优的制冷控制方式，充分发挥间歇式制冷控制方法的效果。
为了实现上述实施例，本发明还提出一种家用水机的制冷控制装置。
图2是根据本发明实施例的家用水机的制冷控制装置的方框示意图。其中，家用水机用于对储水容器内的水进行降温，并在用户不用水时，将低温冷水储备起来，当用户用水时，可随时放出大量的低温冷水。
如图2所示，根据本发明实施例的家用水机的制冷控制装置包括：接收模块1、检测模块2和控制模块3。
其中，接收模块1用于接收用户的制冷指令；检测模块2用于检测家用水机的运行参数，根据本发明的一些实施例，运行参数可为冷凝器的温度、制冷时间、冷水温度、蒸发器温度和环境温度中的一个或多个。
控制模块3用于根据制冷指令控制家用水机进入制冷模式，并获取运行参数，并根据运行参数判断是否满足暂停条件，如果满足暂停条件，则暂停制冷，并进一步判断是否满足重启条件，如果满足重启条件，则进行制冷并重复判断运行参数是否满足暂停条件以及重启条件，直至满足制冷结束条件。
也就是说，在制冷模式下，家用水机进行制冷运行以对家用水机内的水进行降温。在不断循环判断运行参数是否满足暂停条件以及重启条件的过程中，如果家用水机内的水温下降到小于或等于预设的目标水温，则判断满足制冷结束条件，退出制冷模式，控制模块3控制家用水机停止制冷。
家用水机开始进行制冷运行后，开始对储水容器内的水进行降温。随着制冷时间的加长，家用水机中冷凝器的散热可能会达到最大，蒸发温度无法继续下降，此时可判断出运行参数满足暂停条件，之后，控制模块3可通过各种方式控制家用水机短暂停下来以暂停制冷，这样，冷凝器和压缩机的热量快速散向外界，整个家用水机又调整到最佳制冷状态，此时可判断出运行参数判断满足重启条件，控制模块3控制家用水机重新进行制冷运行， 继续将储水容器内的水温往下降。随着制冷时间的继续加长，家用水机中冷凝器的散热可能又会达到最大，蒸发温度也无法继续下降时，家用水机又会短暂停下来，冷凝器和压缩机的热量快速散向外界，家用水机又调整到最佳制冷状态，然后又重新进行制冷运行。
如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温，完成制冷。
也就是说，通过间歇式制冷控制方式，不断调整家用水机的散热状态，使整个家用水机长时间保持在高效率运转状态，直到水温降低到预设的目标水温。
本发明实施例提出的家用水机的制冷控制装置，控制模块在进入制冷模式之后，获取家用水机的运行参数，并根据运行参数判断是否满足暂停条件，如果满足暂停条件，则暂停制冷，进一步判断是否满足重启条件，如果满足重启条件，则进行制冷并重复判断是否满足暂停条件和重启条件，直至满足制冷结束条件。由此，在家用水机的运行过程中，通过暂停制冷使冷凝器、蒸发器的性能重新恢复到最优性能状态，下一次运行时蒸发温度可以降得很低，从而使得冷凝器、蒸发器及压缩机的性能达到多倍的发挥，实现超低水温制冷，提高了制冷能力。并且，该装置还避免了成本增加，避免了冷凝器和蒸发器超负荷运行引起的性能不稳定的不足，提高了家用水机的稳定性。
下面结合以下具体实施例来详细描述本发明实施例的制冷控制方法。
根据本发明的一个具体实施例，运行参数可为家用水机中冷凝器的温度，其中，当冷凝器的温度大于第一预设温度阈值时控制模块判断满足暂停条件，并在冷凝器的温度小于第二预设温度阈值时控制模块3判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如暂停时间是否达到时间阈值。
需要说明的是，检测模块2可包括第一温度传感器，第一温度传感器可安装在冷凝器上以检测冷凝器的温度。更具体地，第一温度传感器可安装在冷凝器的末端以检测冷凝器末端的温度。
家用水机进行制冷运行，冷水温度开始下降，并且冷凝器的温度开始上升，当冷凝器的温度达到第一预设温度阈值时，控制模块3判断满足暂停条件，家用水机暂时停下来，然后冷凝器向空气中快速散热，冷凝器的温度快速下降，当冷凝器的温度下降到小于第一预设温度阈值时，控制模块3判断满足重启条件，家用水机重新进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温。这样即可通过间歇式制冷控制方式完成制冷。
根据本发明的另一个具体实施例，运行参数可为家用水机的制冷时间，其中，当制冷时间大于第一预设时间阈值时控制模块判断满足暂停条件，并在暂停时间大于第二预设时 间阈值时控制模块判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如冷凝器的温度是否小于预设温度阈值。
需要说明的是，可通过第一计时器对制冷时间进行计时以及可通过第二计时器对暂停时间进行计时。更具体地，当家用水机进入制冷模式时，控制模块3可控制第一计时器从0开始进行计时以记录制冷时间；当家用水机暂停制冷时，控制模块3可控制第二计时器从0开始进行计时以记录暂停时间。
先在家用水机上设定第一预设时间阈值，再设定第二预设时间阈值。家用水机开始进行制冷运行，冷水温度开始下降，当家用水机制冷运行到第一预设时间阈值时，控制模块3判断满足暂停条件，此时冷凝器散热达最大值，蒸发温度无法继续降低，家用水机暂时停下来，然后冷凝器向空气中快速散热，当家用水机的暂停时间达到第二预设时间阈值时，家用水机调整到最佳制冷状态，控制模块3满足重启条件，重新进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温。这样即可通过间歇式制冷控制方式完成制冷。

需要说明的是，可通过第三计时器对暂停时间进行计时。更具体地，当家用水机暂停制冷时，控制模块3可控制第三计时器从0开始进行计时以记录暂停时间。
家用水机开始进行制冷运行，水温向多个设定水温中的一个下降，当将常温水降到多个设定水温中的一个时，冷凝器的散热达到最大值，蒸发温度无法继续下降，控制模块3控制家用水机短暂停止运转，然后冷凝器向空气中快速散热，当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，控制模块3判断满足重启条件。然后，家用水机重新进行制冷运行，水温再向多个设定水温中的另一个下降，当将冷水温度下降到多个设定水温中的另一个时，冷凝器的散热达到最大值，控制模块3控制家用水机短暂停止运转，当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，家用水机又进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得很低很低，例如将水温降至预设的目标水温，这样即可通过间歇式制冷控制方式完成制冷。
另外，需要说明的是，多个设定水温可按降序排列，通过间歇制冷冷水温度可逐渐下 降直至达到目标水温。举例来说，多个设定水温可包括水温1、水温2和水温3，其中，水温1大于水温2且水温2大于水温3，并且水温3为目标水温。这样，家用水机进行制冷运行后，冷水温度先向水温1下降，当冷水温度达到水温1时，家用水机暂时停下来。当暂停时间达到第三预设时间阈值时，家用水机重新进行制冷运行，冷水温度向水温2下降，当冷水温度达到水温2时，家用水机暂时停下来。当暂停时间达到第三预设时间阈值时，家用水机再次进行制冷运行，冷水温度向水温3下降，当冷水温度达到水温3时，冷水温度达到目标水温，停止制冷。
根据本发明的再一个具体实施例，运行参数可为家用水机的蒸发器温度和冷水温度，其中，当蒸发器温度与冷水温度之差小于第三预设温度阈值时控制模块判断满足暂停条件。
需要说明的是，检测模块2可包括第二温度传感器和第三温度传感器，第三温度传感器可安装在蒸发器上以及检测蒸发器温度，第二温度传感器可安装在储水容器上以及检测冷水温度。
进一步地，在暂停时间大于第三预设时间阈值时控制模块3判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如冷凝器的温度是否小于预设温度阈值。
需要说明的是，可通过第三计时器对暂停时间进行计时。更具体地，当家用水机暂停制冷时，控制模块3可控制第三计时器从0开始进行计时以记录暂停时间。
家用水机开始进行制冷运行，冷水温度开始下降，当蒸发器温度与冷水温度之间的温度差小于第三预设温度阈值时，控制模块3判断满足暂停条件，控制家用水机暂时停下来，然后冷凝器向空气中快速散热。当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，控制模块3判断满足重启条件，然后家用水机重新进行制冷运行，冷水温度继续下降，当蒸发器温度与下降后的冷水温度之间的温度差达到第三预设温度阈值时，控制模块3控制家用水机又暂时停止运转。当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，家用水机又进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得非常低，例如将水温降至预设的目标水温，这样即可通过间歇式制冷控制方式完成制冷。

进一步地，在暂停时间大于第三预设时间阈值时控制模块3判断满足重启条件。当然，也可以根据其他条件判断是否满足重启条件，例如冷凝器的温度是否小于预设温度阈值。
需要说明的是，可通过第三计时器对暂停时间进行计时。更具体地，当家用水机暂停制冷时，控制模块3可控制第三计时器从0开始进行计时以记录暂停时间。
家用水机开始进行制冷运行，冷水温度开始下降，并且冷凝器的温度开始上升，当冷凝器的温度与环境温度间之间的温度差小于第四预设温度阈值时，控制模块3判断满足暂停条件，控制家用水机暂时停下来，然后冷凝器向空气中快速散热，冷凝器的温度快速下降。当暂停时间达到第三预设时间阈值时，家用水机调整到最佳制冷状态，控制模块3判断满足重启条件，然后，家用水机重新进行制冷运行，冷水温度继续下降，并且冷凝器的温度继续上升，当冷凝器的温度与环境温度间之间的温度差小于第四预设温度阈值时，家用水机又暂时停止运转。当暂停时间达到第三预设时间阈值时，家用水机又调整到最佳制冷状态，家用水机又进行制冷运行。如此不断的循环运行，直到把储水容器内的水温降得非常低，例如将水温降至预设的目标水温，这样即可通过间歇式制冷控制方式完成制冷。
换言之，可使冷凝器温度和环境温度之间的温差始终保持在最大温差，以利于家用水机向空气散热，当冷凝器温度和环境温度之差小于第四预设温度阈值时，家用水机又短暂停止制冷运行，使冷凝器及压缩机的热量快速散向外界，在家用水机调整到最佳制冷状态时再启动制冷运行，如此不断的循环运行，直到冷水温度达到超低的目标水温。
此外，在本发明的其他实施例中，控制模块3也可以把冷凝器的温度、制冷时间、冷水温度、蒸发器温度与冷水温度之差以及冷凝器温度和环境温度之差同时结合起来进行制冷控制，通过交错使用上述判断条件，获得最优的制冷控制，充分发挥间歇式制冷控制的效果。
