技术领域technical field

本发明涉及冷藏冷冻领域，特别涉及一种保鲜装置及冰箱。The invention relates to the field of refrigeration and freezing, in particular to a fresh-keeping device and a refrigerator.

背景技术Background technique

现有冰箱真空保鲜技术，采用真空泵抽取容纳空间内的空气，减少氧气含量，增强保鲜效果。众所周知，正常容纳空间内气体初始氧气含量约20％，氮气含量约80％，假设10L的空间内，初始氧气约2L。采用真空泵抽取容纳空间内的空气时，是把氧气和氮气同时抽走，当抽走1L氧气时，同时抽走了4L的氮气，此时空间内剩余1L氧气和4L氮气，形成较大负压，约-0.5bar；由于内外压差大，为防止抽屉框架变形，整体结构需要采用加强设计，如需要加厚、加强材料及增加加强筋设计等，造成材料和容积的损耗大.The existing refrigerator vacuum preservation technology uses a vacuum pump to extract the air in the storage space, reduces the oxygen content, and enhances the preservation effect. As we all know, the initial oxygen content of gas in a normal storage space is about 20%, and the nitrogen content is about 80%. Assuming that in a 10L space, the initial oxygen content is about 2L. When a vacuum pump is used to extract the air in the storage space, oxygen and nitrogen are taken away at the same time. When 1L of oxygen is taken out, 4L of nitrogen is taken away at the same time. At this time, there are 1L of oxygen and 4L of nitrogen in the space, forming a large negative pressure. , about -0.5bar; Due to the large internal and external pressure difference, in order to prevent the deformation of the drawer frame, the overall structure needs to adopt a reinforced design, such as the need to thicken, strengthen the material and increase the rib design, etc., resulting in a large loss of material and volume.

发明内容Contents of the invention

本发明旨在至少解决现有技术中存在的技术问题之一。为此，本发明提出一种保鲜装置，该保鲜装置可以使存储空间内形成低氧负压状态，并可以使空间内保持一段时间的低氧负压状态。The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a fresh-keeping device, which can form a hypoxic negative pressure state in the storage space, and can maintain the hypoxic negative pressure state in the space for a period of time.

如图1、图2、图3所示，本发明实施例的保鲜装置200，用于冰箱100，冰箱100可以指的是广义的制冷存储设备，例如电冰箱、电冰柜、冷藏柜等等。保鲜装置200包括框架210、抽屉220和除氧模组300，其中，框架210设置有容纳空间213，在框架210的一侧设置有开口214，框架210的壁上设有透气孔215，透气孔215与容纳空间213连通，抽屉220能通过开口214进入并收容于容纳空间213中，从而使抽屉220与框架210配合形成密闭的收容空间，以存储果蔬等食材，除氧模组设置于框架的透气孔处，容纳空间的氧气可通过透气孔进入除氧模组，通过除氧模组以消耗收容空间内部的氧气，降低收容空间内的氧含量，从而使收容空间形成低氧负压环境。As shown in Fig. 1, Fig. 2, and Fig. 3, the fresh-keeping device 200 of the embodiment of the present invention is used in arefrigerator 100, and therefrigerator 100 may refer to a generalized refrigeration storage device, such as a refrigerator, a freezer, a freezer, and the like. Thepreservation device 200 includes a frame 210, adrawer 220 and anoxygen removal module 300, wherein the frame 210 is provided with anaccommodation space 213, and anopening 214 is provided on one side of the frame 210, and the wall of the frame 210 is provided with aventilation hole 215, and theventilation hole 215 communicates with thestorage space 213, and thedrawer 220 can enter and be accommodated in thestorage space 213 through theopening 214, so that thedrawer 220 cooperates with the frame 210 to form an airtight storage space for storing fruits and vegetables and other foodstuffs, and the oxygen removal module is arranged on the frame. At the vent hole, the oxygen in the storage space can enter the oxygen removal module through the ventilation hole, and the oxygen removal module consumes the oxygen in the storage space and reduces the oxygen content in the storage space, so that the storage space forms a hypoxic negative pressure environment.

本发明实施例的保鲜装置200采用除氧模组300，使除氧模组300与容纳空间213内的空气接触，空气中的氧气与除氧模组300反应，被置换到外部，从而在该收容空间内获得低氧环境，该低氧环境能有效抑制水果蔬菜呼吸作用，减少有机物质的消耗，并且低氧环境能满足果蔬细胞最基本的生存要求，能维持细胞生命力，利于果蔬保鲜。还可以有效抑制好氧细菌和厌氧细菌滋生繁殖，防止微生物腐败果蔬。另外，低氧也能抑制某些酶的活性，抑制乙烯产生，延缓后熟和衰老过程，长期保持果实的营养新鲜；而且，在形成低氧环境的同时，除氧模组只会和氧气反应，氮气不会被消耗转移，由于容纳空间内气体初始氧气含量约20％，氮气含量约80％，假设10L的空间内，初始氧气约2L，当氧气消耗掉1L时，空间内剩余1L氧气和8L氮气，容纳空间内形成的负压较小，约-0.1bar，相对于采用真空泵除氧的方式而言，达到同样氧含量的本发明实施例的保鲜装置的容纳空间负压值较小，因此本发明实施例的保鲜装置对结构强度要求较低，无须对保鲜装置的整体结构采用加强设计，从而降低材料成本，减少容积的损耗；并且，当容纳空间内氧气被逐渐消耗掉时，由于容纳空间内相对密封，可减缓外部空气渗透进容纳空间内的速度，从而使容纳空间内保持一段时间的低氧负压状态；并且，相对于采用真空泵抽取容纳空间内的空气、减少氧气含量保鲜装置而言，本发明实施例的保鲜装置摒弃了真空泵的使用，具有噪音小的特点，因此本发明实施例的保鲜装置更加静音。The fresh-keepingdevice 200 of the embodiment of the present invention adopts theoxygen removal module 300, makes theoxygen removal module 300 contact with the air in theaccommodation space 213, and the oxygen in the air reacts with theoxygen removal module 300 and is displaced to the outside, thereby The containment space obtains a hypoxic environment, which can effectively inhibit the respiration of fruits and vegetables, reduce the consumption of organic matter, and the hypoxic environment can meet the most basic survival requirements of fruit and vegetable cells, maintain the vitality of cells, and facilitate the preservation of fruits and vegetables. It can also effectively inhibit the growth and reproduction of aerobic bacteria and anaerobic bacteria, and prevent microorganisms from spoiling fruits and vegetables. In addition, low oxygen can also inhibit the activity of certain enzymes, inhibit the production of ethylene, delay the ripening and aging process, and keep the nutrition of the fruit fresh for a long time; moreover, while forming a low oxygen environment, the oxygen removal module will only react with oxygen , nitrogen will not be consumed and transferred, because the initial oxygen content of the gas in the holding space is about 20%, and the nitrogen content is about 80%, assuming that in a 10L space, the initial oxygen is about 2L, when 1L of oxygen is consumed, the remaining 1L of oxygen and 8L nitrogen, the negative pressure formed in the storage space is small, about -0.1bar. Compared with the way of using vacuum pump to remove oxygen, the negative pressure value of the storage space of the fresh-keeping device of the embodiment of the present invention with the same oxygen content is small, Therefore, the fresh-keeping device in the embodiment of the present invention has lower requirements on the structural strength, and there is no need to adopt a reinforced design for the overall structure of the fresh-keeping device, thereby reducing material costs and reducing volume loss; and, when the oxygen in the containing space is gradually consumed, due to The storage space is relatively sealed, which can slow down the penetration of external air into the storage space, so that the storage space maintains a low oxygen negative pressure state for a period of time; and, compared with using a vacuum pump to extract the air in the storage space and reduce the oxygen content to keep fresh As far as the device is concerned, the fresh-keeping device of the embodiment of the present invention abandons the use of a vacuum pump and has the characteristics of low noise, so the fresh-keeping device of the embodiment of the present invention is more silent.

在一些实施例中，除氧模组300为电化学除氧模组，电化学除氧模组设置成通过电解反应消耗收容空间内部的氧气，以使容纳空间213内形成低氧负压状态。In some embodiments, thedeoxygenation module 300 is an electrochemical deoxygenation module, and the electrochemical deoxygenation module is configured to consume the oxygen in the storage space through electrolytic reaction, so as to form a low oxygen negative pressure state in thestorage space 213 .

在除氧模组300内部设有阴极电极和阳极电极(图中未示出)，阴极电极通过防水透气膜与空气接触，除氧模组的工作原理是：空气中的氧气通过防水透气膜渗透进入电解液箱，同时空气中的氮气被防水透气膜阻挡在电解液箱外，并在阴极作用下与水产生电化学反应，生成氢氧根离子，同时，在阳极产生电化学反应，氢氧根离子反应生成水和氧气，从而将空气的中的氧气置换出来，并通过排气孔排出除氧模组300外面，从而使抽屉内部氧气含量降低，进而达到保鲜作用。A cathode electrode and an anode electrode (not shown in the figure) are arranged inside theoxygen removal module 300, and the cathode electrode is in contact with the air through a waterproof and breathable membrane. The working principle of the oxygen removal module is: the oxygen in the air penetrates through the waterproof and breathable membrane Entering the electrolyte tank, nitrogen in the air is blocked outside the electrolyte tank by a waterproof and breathable membrane, and reacts electrochemically with water under the action of the cathode to generate hydroxide ions. At the same time, an electrochemical reaction occurs at the anode, hydrogen and oxygen The root ions react to generate water and oxygen, so as to replace the oxygen in the air, and discharge it out of theoxygen removal module 300 through the exhaust hole, thereby reducing the oxygen content inside the drawer, thereby achieving the effect of freshness preservation.

使用电化学除氧模组时，由于模组只会和氧气反应，氮气不会被消耗转移，容纳空间内气体初始氧气含量约20％，氮气含量约80％，假设10L的空间内，初始氧气约2L，当氧气消耗掉1L时，空间内剩余1L氧气和8L氮气，此时容纳空间内形成的负压较小，约-0.1bar，对结构强度要求较低，无须对保鲜装置的整体结构采用加强设计，从而降低材料成本，减少容积的损耗；并且采用电化学除氧模组在实现降低氧气含量、增强保鲜效果的目的的同时，由于电化学除氧模组无噪音产生，使采用该除氧模组300的保鲜装置更加静音。When using the electrochemical deoxygenation module, since the module will only react with oxygen, the nitrogen will not be consumed and transferred. The initial oxygen content of the gas in the storage space is about 20%, and the nitrogen content is about 80%. Assuming that in a 10L space, the initial oxygen About 2L. When 1L of oxygen is consumed, 1L of oxygen and 8L of nitrogen remain in the space. At this time, the negative pressure formed in the storage space is small, about -0.1bar, and the requirements for structural strength are low, and there is no need for overall structure of the fresh-keeping device. Reinforced design is adopted to reduce material cost and volume loss; and the electrochemical deoxygenation module is used to achieve the purpose of reducing the oxygen content and enhancing the freshness preservation effect. The fresh-keeping device of theoxygen removal module 300 is more silent.

可以理解的是，除氧模组300还可采用氧气吸附装置等，吸附氧气后剩余的气体返回容纳空间内，同样可在形成低氧环境的同时，氮气不会被消耗转移，容纳空间内形成的负压较小，对结构强度要求较低，无须对保鲜装置的整体结构采用加强设计，从而降低材料成本，减少容积的损耗。It can be understood that thedeoxygenation module 300 can also use an oxygen adsorption device, etc., and the remaining gas after absorbing oxygen is returned to the storage space. Similarly, while forming a low-oxygen environment, the nitrogen will not be consumed and transferred, and the nitrogen gas will be formed in the storage space. The negative pressure of the fresh-keeping device is small, and the requirements for the structural strength are low. It is not necessary to adopt a reinforced design for the overall structure of the fresh-keeping device, thereby reducing material costs and volume loss.

参照图2、图5，在一些实施例中，电化学除氧模组上设置有加水孔310和排气孔320，由于电化学除氧模组在工作过程中，排气孔320排出的氧气会带走部分水分，导致电化学除氧模组电解液箱内电解液的水分逐渐减少，影响除氧模组的正常工作，需要客户自行定期补充水分。通过在电化学除氧模组上设置加水孔310，在电解液箱内的液面达到预定低的位置时，可通过加水孔310向电解液箱补水，从而使电解液箱内的液位维持在正常范围内。Referring to Fig. 2 and Fig. 5, in some embodiments, the electrochemical oxygen removal module is provided with awater filling hole 310 and anexhaust hole 320, and the oxygen discharged from theexhaust hole 320 is discharged during the working process of the electrochemical oxygen removal module. Part of the moisture will be taken away, resulting in the gradual decrease of the electrolyte moisture in the electrolyte tank of the electrochemical oxygen removal module, affecting the normal operation of the oxygen removal module, and the customer needs to replenish water regularly by himself. By setting thewater filling hole 310 on the electrochemical deoxygenation module, when the liquid level in the electrolyte tank reaches a predetermined low position, water can be replenished to the electrolyte tank through thewater filling hole 310, thereby maintaining the liquid level in the electrolyte tank within the normal range.

参照图1、图2，在一些实施例中，框架210包括内框架211和外框架212，其中，容纳空间213设置在内框架211内，开口214设置在内框架211的一侧，透气孔215设置在内框架211远离开口214的侧壁；外框架212设置在内框架211上，除氧模组300设置在内框架211和外框架212之间，从而使保鲜装置200结构紧凑，提升保鲜装置200的有效利用空间。Referring to Fig. 1 and Fig. 2, in some embodiments, the frame 210 includes aninner frame 211 and anouter frame 212, wherein theaccommodating space 213 is arranged in theinner frame 211, theopening 214 is arranged on one side of theinner frame 211, and the ventilation holes 215 Set on the side wall of theinner frame 211 away from theopening 214; theouter frame 212 is set on theinner frame 211, and theoxygen removal module 300 is set between theinner frame 211 and theouter frame 212, so that the structure of the fresh-keepingdevice 200 is compact, and the fresh-keeping device can be lifted 200 of effective use of space.

在一些实施例中，除氧模组300通过固定结构400可拆卸地设置在内框架211上，以便于除氧模组300和保鲜装置200的维护。In some embodiments, theoxygen removal module 300 is detachably arranged on theinner frame 211 through the fixingstructure 400 , so as to facilitate the maintenance of theoxygen removal module 300 and the fresh-keepingdevice 200 .
