Description
技术领域Technical field
本实用新型涉及制冷技术领域,尤其涉及一种冷柜。The utility model relates to the field of refrigeration technology, in particular to a refrigerator.
背景技术Background technique
目前直冷冷柜会存在大量结霜的问题,其中一个原因是开关柜门时候湿空气进入内遇冷冷凝结霜,还有一个比较重要的因素为:在压缩机开停机时,柜内外压强产生变化,柜外的湿空气通过门缝处进入到柜内,然后湿空气预冷凝结成霜。At present, there are a lot of frost problems in direct-cooling freezers. One of the reasons is that when the cabinet door is opened and closed, the moist air enters the interior and encounters cold condensation and frost. Another important factor is: when the compressor is turned on and off, the pressure inside and outside the cabinet is generated. The humid air outside the cabinet enters the cabinet through the door crack, and then the humid air is pre-cooled and condensed into frost.
行业内常用的降低冷柜内结霜量的方法是在冷柜柜口处开孔,利用通气管与外界连接,中间设置低霜模块,通过内胆的低温为低霜模块降温,进而对空气中的水分冷凝,降低进入柜体内的湿空气的比例,从而达到除霜的目的,为了达到充分冷凝水汽的目的,低霜模块内设有翅片,但该种方法仍存在冷凝不彻底的问题。A commonly used method in the industry to reduce the amount of frost in the freezer is to open a hole at the mouth of the freezer, use a ventilation pipe to connect it to the outside world, and set up a low-frost module in the middle. The low-frost module is cooled by the low temperature of the inner tank, thereby reducing the temperature in the air. Moisture condenses and reduces the proportion of humid air entering the cabinet, thereby achieving the purpose of defrosting. In order to achieve the purpose of fully condensing water vapor, the low-frost module is equipped with fins, but this method still has the problem of incomplete condensation.
鉴于此,有必要设计一种新的冷柜来解决上述问题。In view of this, it is necessary to design a new refrigerator to solve the above problems.
