技术领域Technical field

本发明涉及冰箱储物技术领域，特别是涉及一种抽气泵组件和冷藏冷冻装置。The invention relates to the technical field of refrigerator storage, in particular to an air pump assembly and a refrigerating and freezing device.

背景技术Background technique

随着生活品质的提高，消费者对冰箱、冷柜等冷藏冷冻装置的食品保鲜要求越来越高。气调保鲜技术一般性地是指通过调节储存物所处封闭空间的气体氛围(气体成分比例或气体压力)的方式来来延长食品贮藏寿命的技术，其基本原理为：在一定的封闭空间内，通过各种调节方式得到不同于正常空气成分的气体氛围，以抑制导致储存物(通常为食材)腐败变质的生理生化过程及微生物的活动。特别地，在本申请中，所讨论的气调保鲜将专门针对于对气体成分比例进行调节的气调保鲜技术。With the improvement of the quality of life, consumers have higher and higher requirements for food preservation of refrigerators, freezers and other refrigerating and freezing devices. The modified atmosphere preservation technology generally refers to a technique for prolonging the storage life of a food by adjusting the gas atmosphere (gas composition ratio or gas pressure) of the enclosed space in which the storage is located, and the basic principle is: in a certain closed space. A gas atmosphere different from the normal air component is obtained by various adjustment methods to suppress physiological and biochemical processes and microbial activities leading to spoilage of the stored matter (usually the foodstuff). In particular, in the present application, the modified atmosphere preservation will be specifically directed to a modified atmosphere preservation technique that adjusts the proportion of gas components.

本领域技术人员均知晓，正常空气成分包括(按体积百分比计，下文同)：约78％的氮气，约21％的氧气，约0.939％的稀有气体(氦、氖、氩、氪、氙、氡)、0.031％的二氧化碳，以及0.03％的其他气体和杂质(例如，臭氧、一氧化氮、二氧化氮、水蒸气等。在气调保鲜领域，通常采用向封闭空间充入富氮气体来降低氧气含量的方式来获得富氮贫氧的保鲜气体氛围。这里，本领域技术人员均知晓，富氮气体是指氮气含量超过上述正常空气中氮气含量的气体，例如其中的氮气含量可为95％～99％，甚至更高；而富氮贫氧的保鲜气体氛围是指氮气含量超过上述正常空气中氮气含量、氧气含量低于上述正常空气中氧气含量的气体氛围。It is known to those skilled in the art that normal air components include (by volume percent, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% rare gases (氦, 氖, argon, krypton, xenon,氡), 0.031% of carbon dioxide, and 0.03% of other gases and impurities (for example, ozone, nitrogen monoxide, nitrogen dioxide, water vapor, etc.. In the field of modified atmosphere preservation, it is usually used to fill the enclosed space with nitrogen-enriched gas. The oxygen content is reduced to obtain a nitrogen-rich and oxygen-poor fresh gas atmosphere. Here, those skilled in the art know that the nitrogen-enriched gas refers to a gas having a nitrogen content exceeding the nitrogen content in the above-mentioned normal air, for example, the nitrogen content may be 95. % to 99%, or even higher; and the nitrogen-rich and oxygen-poor fresh gas atmosphere refers to a gas atmosphere in which the nitrogen content exceeds the above-mentioned normal air nitrogen content and the oxygen content is lower than the oxygen content in the above-mentioned normal air.

气调保鲜技术的历史虽然可追溯到1821年德国生物学家发现水果蔬菜在低氧水平时能减少代谢作用开始。但直到目前为止，由于传统上用于气调保鲜的制氮设备体积庞大、成本高昂，导致该技术基本上还是局限于使用在各种大型的专业贮藏库上(储藏容量一般至少30吨以上)。可以说，采用何种适当的气体调节技术和相应装置才可能经济地将气调***小型化、静音化，使其适用于家庭或个人用户，是气调保鲜领域技术人员一直渴望解决但始终未能成功解决的技术难题。The history of modified atmosphere preservation technology dates back to 1821 when German biologists discovered that fruits and vegetables could reduce metabolism at low oxygen levels. But until now, due to the large size and high cost of nitrogen-making equipment traditionally used for gas-conditioning preservation, the technology is basically limited to use in various large-scale professional storage (the storage capacity is generally at least 30 tons). . It can be said that the appropriate gas regulation technology and corresponding equipment can economically reduce and quiet the air-conditioning system, making it suitable for home or individual users. It is a constant desire of technicians in the field of atmosphere preservation and preservation. A technical problem that can be successfully solved.

另外，气调保鲜技术需要使用抽气泵将氧气抽出，但抽气泵运行噪音较大。因此，如将该技术应用于冰箱，如何对抽气泵进行降噪也是亟待解决的问题。In addition, the modified atmosphere preservation technology needs to use an air pump to pump out oxygen, but the pump has a relatively high noise operation. Therefore, if the technology is applied to a refrigerator, how to reduce the noise of the air pump is also an urgent problem to be solved.

The fresh gas atmosphere reduces the oxygen content of the fruit and vegetable storage space, reduces the aerobic respiration of fruits and vegetables, ensures the basic respiration, and prevents the anaerobic respiration of fruits and vegetables, thereby achieving the long-term preservation of fruits and vegetables.

进一步地，本发明的冷藏冷冻装置中，抽气泵设置于压缩机仓内，无需额外占用其他空间特别是储物空间，因此不会增大冷藏冷冻装置的额外体积，可使冷藏冷冻装置的结构紧凑。Further, in the refrigerating and freezing device of the present invention, the air pump is disposed in the compressor chamber without additionally occupying other space, particularly the storage space, so that the extra volume of the refrigerating and freezing device is not increased, and the structure of the refrigerating and freezing device can be compact.

进一步地，本发明的冷藏冷冻装置不仅保鲜效果好，而且对储物容器等的刚性、强度要求较低，实现要求很低，则成本也很低。而且，解决了气调保鲜领域技术人员一直渴望解决但始终未能成功解决的上述技术难题。冷藏冷冻装置不仅体积小，而且噪音也很低，特别适用于家庭和个人使用。Further, the refrigerating and freezing apparatus of the present invention not only has a good fresh-keeping effect, but also has low rigidity and strength requirements for a storage container or the like, and has low requirements, and the cost is also low. Moreover, the above technical problems that the technicians in the field of modified atmosphere preservation have been eager to solve but have not been successfully solved have been solved. Refrigerated and refrigerated units are not only small in size but also low in noise, making them especially suitable for home and personal use.
