Description
本发明涉及冰箱领域，尤其涉及一种风冷冰箱的控制方法、装置及风冷冰箱。
风冷冰箱是一种采用风冷设计进行制冷的冰箱。其工作原理为：由于空气温度高、蒸发器温度低，当高温空气流经内置的蒸发器时，直接发生热交换，空气的温度就会降低，形成冷气，并通过冷气降低冰箱的温度。
然而，空气中存在着水蒸气，并且蒸发器的温度远低于空气的露点温度，当蒸发器与空气进行热交换时，空气中的水蒸气遇冷会在蒸发器上凝结形成冰霜。风冷冰箱的蒸发器上的冰霜会增加蒸发器与空气的热阻，阻碍蒸发器与空气间的热交换，从而影响制冷效果，增加耗电量。因此，在风冷冰箱的使用过程中，需要定期的将蒸发器上结的冰霜清理掉。
在现有技术中，主流的风冷冰箱化霜的方法是通过热蒸发来去除蒸发器上的冰霜，即风冷冰箱会定期暂停制冷，并启动电加热器，通过电加热器加热，利用电加热器产生的热量将蒸发器上结的冰霜融化成水，再通过专用的导管排出。
但是，在风冷冰箱化霜的过程中，电加热器产生的热量不但会使蒸发器温度升高，也会使放置蒸发器的冷冻室的温度一起升高，导致冷冻室再次制冷的时间长，增加了风冷冰箱的能耗。
发明内容
本发明的实施例提供一种风冷冰箱的控制方法、装置及风冷冰箱，用以缩短冷冻室再次制冷的时间，达到降低风冷冰箱的能耗的目的。
为达到上述目的，本发明的实施例采用如下技术方案：
第一方面，本发明实施例提供了一种风冷冰箱的控制方法，应用于风冷冰箱，所述风冷冰箱包括：冷冻室及冷藏室，设置在所述冷冻室内的蒸发器，连接所述冷冻室及所述冷藏室的风道，设置在所述风
道上的风门，所述风门的进风口与所述冷冻室连通，所述风门的出风口与所述风道连通，该方法包括：
通过对所述蒸发器进行加热，以实现化霜处理；
开启所述风门，以使得对所述蒸发器加热时产生的热量通过所述风道流进所述冷藏室。
第二方面，本发明实施例提供了一种风冷冰箱的控制装置，所述风冷冰箱包括：冷冻室及冷藏室，设置在所述冷冻室内的蒸发器，连接所述冷冻室及所述冷藏室的风道，设置在所述风道上的风门，所述风门的进风口与所述冷冻室连通，所述风门的出风口与所述风道连通，所述控制装置，包括：

在第三方面，本发明实施例提供了一种风冷冰箱，包括：冷冻室及冷藏室，设置在所述冷冻室内的蒸发器，连接所述冷冻室及所述冷藏室的风道，设置在所述风道上的风门，所述风门的进风口与所述冷冻室连通，所述风门的出风口与所述风道连通，还包括：控制装置；其中，

本发明实施例提供的一种风冷冰箱的控制方法、装置及风冷冰箱，通过对蒸发器进行加热，以实现化霜处理；开启风门，以使得对所述蒸发器加热时产生的热量通过风道流进冷藏室。这样，相对于现有技术中仅通过冷冻室消除对蒸发器加热时产生的热量使得冷冻室的温度较高而言，本发明通过开启连接冷冻室与冷藏室的风道上的风门，使冷冻室和冷藏室的空间相通，可以让对蒸发器加热时产生的一部分热量从冷冻室传递到冷藏室，即冷藏室可以分担一部分热量，从而降低了冷冻室的温度回升，而冷冻室的温度回升越低，冷冻室再次制冷的时间越短，进而缩短了风冷冰箱冷冻室再次制冷的时间，降低了风冷冰箱的能耗。上述方法克服了现有技术中因风冷冰箱化霜的过程中，对蒸发器加热时产生的热量使冷冻室的温度升高导致冷冻室再次制冷
的时间长、风冷冰箱能耗增加的问题，实现了缩短风冷冰箱冷冻室再次制冷的时间，降低风冷冰箱的能耗的目的。
为了更清楚地说明本发明实施例的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

图4为本发明实施例提供的风冷冰箱的控制方法的又一控制流程图；

图6为图5所示的风冷冰箱的控制装置的开启单元的结构示意图。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供的一种风冷冰箱的控制方法应用于风冷冰箱。风冷冰箱包括：冷冻室及冷藏室，设置在冷冻室内的蒸发器，连接冷冻室及冷藏室的风道，设置在风道上的风门。风门的进风口与冷冻室连通，风门的出风口与风道连通。
其中，冷冻室的温度一般要低于零下18℃(摄氏度)；冷藏室的温度在5℃左右。当然，冷藏室和冷冻室的温度也可以根据实际要求或者经验进行设置，本实施例对此并不做限制。
蒸发器一般设置在冷冻室内，是风冷冰箱的主要制冷设备，起到制冷的作用。
连接冷冻室及冷藏室的风道，可以实现冷气在风冷冰箱的各间室内循环。
风道上的风门，若在开启的情况下，实现冷冻室和冷藏室的空间连通；若在关闭的情况下，使冷藏室和冷冻室的空间不连通。
需要说明的是，风冷冰箱中还包括其他部件，例如，压缩机，风机等，本发明对风冷冰箱中包含的部件不做限制。
本发明实施例提供的一种风冷冰箱的控制方法，如图1所示，包括如下几个步骤：
S101、通过对所述蒸发器进行加热，以实现化霜处理。
具体的，风冷冰箱的控制装置确定需要对蒸发器进行化霜处理后，对所述蒸发器进行加热以去除蒸发器上的冰霜。即为，对蒸发器进行加热处理，利用热蒸发来去除蒸发器上的冰霜。
进一步的，风冷冰箱的控制装置可以根据风冷冰箱的运行时间，来判断是否对蒸发器进行化霜处理。即为确定风冷冰箱的运行时间是否达到预设运行时间，若风冷冰箱的运行时间达到预设运行时间，则确定对蒸发器进行化霜处理。若风冷冰箱的运行时间没有达到预设运行时间，则确定风冷冰箱继续正常的运行工作。
或者，风冷冰箱的控制装置也可以根据风冷冰箱冷冻室的当前温度，来判断是否对蒸发器进行化霜处理。这是因为冷冻室的温度一般要低于零下18℃，虽然其温度可以不断变化，但是其最高温度不会超过某个温度值。当冷冻室的温度超过某个温度值时，说明冷冻室的制冷效果较差，使得冷冻室的温度过高，也就是蒸发器的制冷效果较差，此时可以认为蒸发器上的冰箱较多，会增加蒸发器与空气的热阻，阻碍蒸发器与空气间的热交换，从而影响制冷效果。所以，风冷冰箱的控制装置可以通过确定风冷冰箱冷冻室的当前温度是否达到温度门限值，若风冷冰箱冷冻室的当前温度达到温度门限值，则确定对蒸发器进行化霜处理。若风冷冰箱冷冻室的当前温度没有达到温度门限值，则确定风冷冰箱继续正常的运行工作。
需要说明的是，本发明实施例中，风冷冰箱的控制装置也可以根
据风冷冰箱的其他间室的温度确定蒸发器是否需要化霜，例如，根据冷藏室的温度确定是否需要化霜，此时，其对应的温度门限值可以根据需要具体设定。本发明对确定蒸发器是否需要化霜的方法不做限定。
示例性的，风冷冰箱的冷冻室的温度一般要低于零下18℃，根据风冷冰箱冷冻室的温度变化范围，假设温度门限值为零下6℃。若风冷冰箱冷冻室的当前温度达到温度门限值零下6℃，则确定对蒸发器进行化霜处理；若风冷冰箱冷冻室的当前温度低于温度门限值零下6℃，则确定风冷冰箱继续正常的运行工作。
需要说明的是，温度门限值可以根据实际需求进行设置，本发明对此并不做限制。
S102、开启风门，以使得对所述蒸发器加热时产生的热量通过所述风道流进所述冷藏室。
具体的，风冷冰箱的控制装置控制风门开启，使得对蒸发器加热时产生的热量通过风门从冷冻室扩散至冷藏室，以便冷藏室分担对蒸发器加热时产生的部分热量。
需要说明的是，由于风冷冰箱化霜时会暂停制冷，并且风冷冰箱中的风机停止工作，这样对蒸发器加热时产生的热量是慢慢扩散到冷藏室的，而冷藏室的空间较大、温度相对蒸发器温度较高，所以对蒸发器加热时产生的热量从蒸发器传递到冷藏室时，对冷藏室的温度影响很小。
进一步的，通过在同一台风冷冰箱上，分别对冷藏室和冷冻室选取三个测温点，对其温度进行测试，来对比利用本发明提出的风冷冰箱的控制方法实现蒸发器化霜后对冷冻室和冷藏室的温度的影响，及利用传统的控制方法实现蒸发器化霜后(即为现有技术中的控制方法)对冷冻室和冷藏室的温度的影响，实验数据如表一、表二所示。其中，表一为利用传统的控制方法实现蒸发器化霜后对冷冻室和冷藏室的温度的影响的实验数据。表二为利用本发明提出的风冷冰箱的控制方法实现蒸发器化霜后对冷冻室和冷藏室的温度的影响的实验数据。
表一
表二
通过上述实验数据对比发现，利用本发明提出的风冷冰箱的控制方法对蒸发器化霜后，冷冻室的温度平均回升了28.2℃，而利用传统的控制方法对蒸发器化霜后，冷冻室的温度平均回升了32.1℃。可以看出，利用本发明提出的风冷冰箱的控制方法对蒸发器化霜后冷冻室的温度平均回升比利用传统的控制方法对蒸发器化霜后冷冻室的温度平均回升下降了3.9℃。利用本发明提出的风冷冰箱的控制方法对蒸发器化霜后，冷藏室温度平均回升了4.1℃，而利用传统的控制方法对蒸发器化霜后，冷藏室温度平均回升4.0℃。可以看出，利用本发明提出
的风冷冰箱的控制方法对蒸发器化霜后冷藏室的温度平均回升和利用传统的控制方法对蒸发器化霜后冷藏室的温度平均回升相差很小，可以忽略不计。
由此可知，通过开启风门使得对蒸发器加热时产生的热量通过风道流进冷藏室，降低了冷冻室的温度回升，同时对冷藏室的温度影响很小。这样一来，就缩短了风冷冰箱冷冻室再次制冷的时间，降低了风冷冰箱的能耗。
优选的，如图2所示，步骤S102开启风门具体包括：
S1021、获取与开启所述风门相关的开启参数。
可选的，开启参数可以是对蒸发器加热的加热时间。也可以是对蒸发器加热的加热温度。
需要说明的是，本发明实施例中开启参数还可是其他与开启风门相关的参数，本发明对此并不做限制。
S1022、在所述开启参数满足开启风门的预设条件时，开启所述风门
需要说明的是，开启风门的预设条件与设置的开启参数有关。在开启参数是加热时间时，开启风门的预设条件是加热时间大于预设时间；在开启参数是加热温度时，开启风门的预设条件是加热温度大于预设温度。当然，当开启参数是其他参数值时，开启风门的预设条件随之改变，本发明对此不做限制。
具体的，风冷冰箱的控制装置在获取了开启参数后，可以确定此开启参数是否满足此开启参数对应的开启风门的预设条件。若确定出开启参数不满足开启风门的预设条件，则说明蒸发器上的冰霜并未完全化解，仍需要对蒸发器进行加热以去除蒸发器上的冰霜，而无需将风门打开，以防止热量扩散出冷冻室，降低去除蒸发器上的冰霜的效率。
在确定出开启参数满足开启风门的预设条件时，说明蒸发器上的冰箱已化解完，或将要化解完，可以扩散加热过程产生的热量，以降低冷冻室的温度。此时，可以将冷藏室的风门开启，使得加热过程产生的热量慢慢扩散到冷藏室中，使得冷藏室分担对蒸发器加热时产生
的一部分热量，从而可以更快的降低冷冻室的温度。
可选的，在开启参数是加热时间时，开启风门的预设条件是加热时间大于预设时间，则所述在所述开启参数满足开启风门的预设条件时，开启所述风门包括：在确定所述加热时间大于预设时间时，开启所述风门，如图3所示。
也就是说，将加热时间作为开启风门的参数。在风冷冰箱的控制装置开始对蒸发器进行加热时，记录加热时间。这样，风冷冰箱的控制装置可以根据对蒸发器加热的加热时间，来确定是否可以将加热过程产生的热量扩散至冷藏室。当加热时间大于预设时间时，则说明可以将加热过程产生的热量扩散至冷藏室，当加热时间不大于预设时间时，则说明没有化解完蒸发器上的冰霜，不能将加热过程产生的热量扩散至冷藏室。所以，风冷冰箱的控制装置确定是否开启风门，将加热过程产生的热量扩散至冷藏室时，需要先确定加热时间是否大于预设时间。
可选的，在开启参数是加热温度时，开启风门的预设条件是加热温度大于预设温度，则所述在所述开启参数满足开启风门的预设条件时，开启所述风门包括：在确定所述加热温度大于预设温度时，开启所述风门，如图4所示。
也就是说，将加热温度作为开启风门的参数。在风冷冰箱的控制装置开始对蒸发器进行加热时，开始记录对蒸发器加热的加热温度。这样，风冷冰箱的控制装置可以根据对蒸发器加热的加热温度，来确定是否可以将加热过程产生的热量扩散至冷藏室。当加热温度大于预设温度时，则说明可以将加热过程产生的热量扩散至冷藏室，当加热温度不大于预设温度时，则说明没有化解完蒸发器上的冰霜，不能将加热过程产生的热量扩散至冷藏室。所以，风冷冰箱的控制装置确定是否开启风门，将加热过程产生的热量扩散至冷藏室时，需要先确定加热温度是否大于预设温度。
本发明实施例提供的一种风冷冰箱的控制方法，通过对所述蒸发器进行加热，以实现化霜处理；开启风门，以使得对所述蒸发器加热时产生的热量通过风道流进冷藏室。这样，相对于现有技术中仅通过冷冻室消除对蒸发器加热时产生的热量使得冷冻室的温度较高而言，
本发明通过开启连接冷冻室与冷藏室的风道上的风门，使冷冻室和冷藏室的空间相通，让对蒸发器加热时产生的一部分热量从冷冻室传递到冷藏室，即冷藏室可以分担对蒸发器加热时产生的一部分热量，从而降低了冷冻室的温度回升，而冷冻室的温度回升越低，冷冻室再次制冷的时间越短，进而缩短了风冷冰箱冷冻室再次制冷的时间，降低了风冷冰箱的能耗。上述方法克服了现有技术中因风冷冰箱化霜的过程中，对蒸发器加热时产生的热量使冷冻室的温度升高导致冷冻室再次制冷的时间长、风冷冰箱能耗增加的问题，实现了缩短风冷冰箱冷冻室再次制冷的时间，降低风冷冰箱的能耗的目的。进一步的，通过获取与开启所述风门相关的开启参数，并在所述开启参数满足开启风门的预设条件时，开启所述风门，这样可以在消除蒸发器上的冰霜时，关闭风门，集中对蒸发器加热产生的热量，消除蒸发器上的冰霜；在需要消除对蒸发器加热时产生的热量时，开启风门，在保证消除蒸发器上的冰霜效率的同时，实现通过冷藏室分担对蒸发器加热时产生的一部分热量，降低冷冻室的温度回升，而冷冻室的温度回升越低，冷冻室再次制冷的时间越短，进而缩短风冷冰箱冷冻室再次制冷的时间，降低风冷冰箱的能耗的目的。
本发明实施例提供一种风冷冰箱的控制装置，该风冷冰箱包括：冷冻室及冷藏室，设置在所述冷冻室内的蒸发器，连接所述冷冻室及所述冷藏室的风道，设置在所述风道上的风门，所述风门的进风口与所述冷冻室连通，所述风门的出风口与所述风道连通。
该风冷冰箱的控制装置，如图5所示，包括：
加热单元501，用于对所述蒸发器进行加热，以实现化霜处理。
具体的，加热单元501确定需要对蒸发器进行化霜处理后对所述蒸发器进行加热以去除蒸发器上的冰霜。即为，加热单元501对蒸发器进行加热处理，利用热蒸发来去除蒸发器上的冰霜。
进一步的，加热单元501可以根据风冷冰箱的运行时间，来判断是否对蒸发器进行化霜处理。即为加热单元501确定风冷冰箱的运行时间是否达到预设运行时间，若风冷冰箱的运行时间达到预设运行时间，则确定对蒸发器进行化霜处理。若风冷冰箱的运行时间没有达到预设运行时间，则确定风冷冰箱继续正常的运行工作。
或者，加热单元501也可以根据风冷冰箱冷冻室的当前温度，来
判断是否对蒸发器进行化霜处理。这是因为冷冻室的温度一般要低于零下18℃，虽然其温度可以不断变化，但是其最高温度不会超过某个温度值。当冷冻室的温度超过某个温度值时，说明冷冻室的制冷效果较差，使得冷冻室的温度过高，也就是蒸发器的制冷效果较差，此时可以认为蒸发器上的冰箱较多，会增加蒸发器与空气的热阻，阻碍蒸发器与空气间的热交换，从而影响制冷效果。所以，加热单元501可以通过确定风冷冰箱冷冻室的当前温度是否达到温度门限值，若风冷冰箱冷冻室的当前温度达到温度门限值，则确定对蒸发器进行化霜处理。若风冷冰箱冷冻室的当前温度没有达到温度门限值，则确定风冷冰箱继续正常的运行工作。
需要说明的是，本发明实施例中，加热单元501也可以根据风冷冰箱的其他间室的温度确定蒸发器是否需要化霜，例如，根据冷藏室的温度确定是否需要化霜，此时，其对应的温度门限值可以根据需要具体设定。本发明对确定蒸发器是否需要化霜的方法不做限定。
可选的，加热单元501可以为电加热器。
开启单元502，用于开启所述风门，以使得所述加热单元501对所述蒸发器加热时产生的热量通过所述风道流进所述冷藏室。
具体的，开启单元502控制风门开启，使得对蒸发器加热时产生的热量通过风门从冷冻室扩散至冷藏室，以便冷藏室分担对蒸发器加热时产生的部分热量。
需要说明的是，由于风冷冰箱化霜时会暂停制冷，此时，风冷冰箱中的风机停止工作，这样对蒸发器加热时产生的热量是慢慢扩散到冷藏室的，而冷藏室的空间较大、温度相对蒸发器温度较高，所以对蒸发器加热时产生的热量从蒸发器传递到冷藏室时，对冷藏室的温度影响很小。这样一来，就缩短了风冷冰箱冷冻室再次制冷的时间，降低了风冷冰箱的能耗。
优选的，该风冷冰箱的控制装置的开启单元502，如图6所示，包括：
获取模块5021，用于获取与开启所述风门相关的开启参数。
可选的，开启参数可以是对蒸发器加热的加热时间。也可以是对蒸发器加热的加热温度。
需要说明的是，本发明实施例中开启参数还可是其他与开启风门相关的参数，本发明对此并不做限制。
开启模块5022，用于在确定所述开启参数满足开启风门的预设条件时，开启所述风门。
需要说明的是，开启风门的预设条件与设置的开启参数有关。在开启参数是加热时间时，开启风门的预设条件是加热时间大于预设时间；在开启参数是加热温度时，开启风门的预设条件是加热温度大于预设温度。当然，当开启参数是其他参数值时，开启风门的预设条件随之改变，本发明对此不做限制。
具体的，在获取模块5021获取了开启参数时，开启模块5022可以确定此开启参数是否满足此开启参数对应的开启风门的预设条件。若确定出开启参数不满足开启风门的预设条件，则说明蒸发器上的冰霜并未完全化解，仍需要对蒸发器进行加热以去除蒸发器上的冰霜，而无需将风门打开，以防止热量扩散出冷冻室，降低去除蒸发器上的冰霜的效率。
在开启模块5022确定出开启参数满足开启风门的预设条件时，说明蒸发器上的冰箱已化解完，或将要化解完，可以扩散加热过程产生的热量，以降低冷冻室的温度。此时，开启模块5022控制冷藏室的风门开启，使得对蒸发器加热时产生的热量慢慢扩散到冷藏室中，使得冷藏室分担对蒸发器加热时产生的一部分热量，从而可以更快的降低冷冻室的温度。
优选的，风冷冰箱还包括计时器，在开始对蒸发器进行加热时，计时器开始记录加热时间。此时，开启参数是加热时间，开启风门的预设条件是加热时间大于预设时间，则所述开启模块5022，具体用于在确定所述加热时间大于预设时间时，开启所述风门。
也就是说，将加热时间作为开启风门的参数。在加热单元501开始对蒸发器进行加热时，计时器记录加热时间。这样，开启模块5022可以根据加热单元501对蒸发器加热的加热时间，来确定是否可以将对蒸发器加热时产生的热量扩散至冷藏室。当加热时间大于预设时间时，则说明可以将对蒸发器加热时产生的热量扩散至冷藏室，当加热时间不大于预设时间时，则说明没有化解完蒸发器上的冰霜，不能将
对蒸发器加热时产生的热量扩散至冷藏室。所以，开启模块5022检测是否开启风门，将对蒸发器加热时产生的热量扩散至冷藏室时，需要先确定加热时间是否大于预设时间。
优选的，风冷冰箱还包括温度传感器，且温度传感器设置于蒸发器上，以便温度传感器准确的记录蒸发器的温度。此时，开启参数是加热温度，开启风门的预设条件是加热温度大于预设温度，则所述开启模块5022，具体用于在确定所述加热温度大于预设温度时，开启所述风门。
也就是说，将加热温度作为开启风门的参数。在加热单元501开始对蒸发器进行加热时，温度传感器记录对蒸发器加热的加热温度。这样，开启模块5022可以根据加热单元501对蒸发器加热的加热温度，来确定是否可以将加热过程产生的热量扩散至冷藏室。当加热温度大于预设温度时，则说明可以将对蒸发器加热时产生的热量扩散至冷藏室，当加热温度不大于预设温度时，则说明没有化解完蒸发器上的冰霜，不能将对蒸发器加热时产生的热量扩散至冷藏室。所以，开启模块5022检测是否开启风门，将对蒸发器加热时产生的热量扩散至冷藏室时，需要先确定加热温度是否大于预设温度。
需要说明的是，上述实现只是对开启单元502用于开启所述风门的两种举例，在开启参数不同时，对应的开启风门的条件不同，本发明对此不做限制。
本发明实施例提供的一种风冷冰箱的控制装置，通过加热单元对所述蒸发器进行加热，以实现化霜处理；开启单元开启所述风门，以使得加热单元对蒸发器加热时产生的热量通过风道流进冷藏室。这样，相对于现有技术中仅通过冷冻室消除加热过程产生的热量使得冷冻室的温度较高而言，本发明通过开启连接冷冻室与冷藏室的风道上的风门，使冷冻室和冷藏室的空间相通，让加热单元对蒸发器加热时产生的一部分热量从冷冻室传递到冷藏室，即冷藏室可以分担对蒸发器加热时产生的一部分热量，从而降低了冷冻室的温度回升，而冷冻室的温度回升越低，冷冻室再次制冷的时间越短，进而缩短了风冷冰箱冷冻室再次制冷的时间，降低了风冷冰箱的能耗。上述方法克服了现有技术中因风冷冰箱化霜的过程中，对蒸发器加热时产生的热量使冷冻室的温度升高导致冷冻室再次制冷的时间长、风冷冰箱能耗增加的问
