Abstract

本发明涉及一种包括空气通道(6)的冷却装置(1)，并防止该空气通道(6)被冰霜堵塞。

Description

冷却装置
技术领域
本发明涉及一种包括空气通道的冷却装置，并防止该空气通道由于结霜而堵塞。
背景技术
在现有技术中，存在包括两个储存室的冷却装置，一个是保鲜室，另一个是冷冻室，在风扇的帮助下通过蒸发器冷却的空气，一部分在冷冻室中循环，其余的在保鲜室中循环。完成在保鲜室中的循环之后的空气，通过一空气通道，再次到达冷冻室。
在特别低的储存室温度下，当风扇停止时，蒸发器室中的冷空气流向该空气通道，将此处的温度降至水的凝固点之下。当风扇再次开始运转时，保鲜室中相对湿热的空气开始通过该空气通道导向蒸发器。然而，当在蒸发器的非运转期间，热空气通过变冷的通道时，潮湿的空气在冷表面上凝结并结霜，一段时间之后，空气通道中积累的霜的量增加。从而导致从保鲜室到蒸发器室携带的空气的量减少，因而保鲜室没有得到充分冷却。
在美国专利NOS.3826103，US5255536和EP644385中，公开了在空气通道中包括加热器的冷却装置。
发明目的和内容
本发明的目的是发明一种冷却装置，消除空气通道中的结霜问题。
附图说明
所发明的实现本发明目的的冷却装置在附图中示出，其中：
图1是冷却装置的侧视图。
图2是冷却装置的另一实施例的侧视图。
图中所示的组件标记如下：
1、冷却装置
2、冷冻室
3、保鲜室
4、压缩机
5、蒸发器
6、空气通道
7、抗结霜装置
8、风扇
9、控制装置
10、蒸发器室
11、加热器
具体实施方式
本发明的冷却装置1包括：
压缩机4，其压缩冷却液并使其在冷却循环中流动，
保鲜室3，用于冷却存储于其中的食物，
冷冻室2，用于冷冻存储于其中的食物，并保持比保鲜室3更低的温度，
至少一个蒸发器5，用于将热量从介质转移到冷却液，
至少一个空气通道6，用于空气在保鲜室3和蒸发器5之间通过，和
抗结霜装置7，其当储存室温度T处于某一确定值Tset之下，在压缩机4停止运转期间，防止空气通道6的温度降至水的凝固点之下，从而防止在空气通道6内形成冰霜(图1)。
在本发明的优选实施例中，冷却装置1包括蒸发器室10，蒸发器5设置在其中，该蒸发器室10通过一壁与冷冻室2隔开，并通过空气通道6连接到保鲜室3。
该冷却装置1包括控制装置9，其直接或间接地收集储存室温度信息。
在本发明的一个实施例中，控制装置9包括直接测量储存室温度的热传感器。当温度T降至某一确定值Tset之下时，例如1-5℃，该控制装置9确定空气通道6中存在结霜的风险。
在本发明的另一实施例中，控制装置9测量压缩机4的停机时间toff和运转时间ton，当运转时间比ton/ton+toff，即运转时间ton与总时间ton+toff的比率低于某一确定值时，例如30-40％，确定储存室温度较低可能导致空气通道6中结霜。
在本发明的一个实施例中，抗结霜装置7包括至少一个风扇8，其在压缩机4停止运转期间，当控制装置9确定储存室温度可能导致空气通道6中结霜时运行，从而防止蒸发器室10中的冷空气流入空气通道6中。风扇8在压缩机4运转期间也可提供空气流通。在压缩机4运转或停止运转时风扇8都可以相同的转速运行，或在压缩机4停止后以较低转速运行。
如果储存室温度低于某一确定值T<Tset，在压缩机4停止运转后抗结霜装置7接通。抗结霜装置7在压缩机4停机期间启动风扇8，从而防止冷冻室2中的空气流入空气通道6，并导致该通道的温度下降。风扇8使空气从保鲜室3流通到空气通道6，再从这里流通到蒸发器5。这样，当压缩机4和风扇8一起重新开始运转时，可以防止来自保鲜室的热空气中的湿气凝结和结霜。
在本发明的又一实施例中，抗结霜装置7包括加热器11，其在压缩机4停机后，在控制装置9已经确定储存室温度可能导致空气通道6中结霜的情况下开始运转。加热器11设置在空气通道6中。加热器11可独立启动或与风扇8一起启动。
当储存室温度降至某一确定值之下时T<Tset，抗结霜装置7在压缩机4停机之后开始运转，在压缩机4停止运转期间加热空气通道6，从而防止从蒸发器室10流出的空气冷却空气通道6。这样，当压缩机4和风扇8一起重新开始运转时，就可以防止空气通道6的温度降至水的凝固点之下，并防止从保鲜室3流出的热空气的湿气凝结和结霜。
在本发明的冷却装置1中，通过在压缩机4停机期间使风扇8或加热器11运转，可以防止在较低储存室温度下空气通道6中结霜。从而解决了堵塞空气通道6的问题。
