本发明的冰箱中，因为具有至少两个以上的气调保鲜装置，即具有至少两个以上的气调间室，每一个气调间室都有各自的气调膜组件，并且每一个气调间室都有自己的温度值范围，实现不同食材的保鲜需求。In the refrigerator of the present invention, because there are at least two or more air-conditioning fresh-keeping devices, that is, there are at least two or more air-conditioning compartments, each air-conditioning compartment has its own air-conditioning membrane assembly, and each air-conditioning compartment has its own air-conditioning membrane assembly. Each compartment has its own temperature range to meet the freshness requirements of different ingredients.
进一步地，至少两个以上的气调保鲜装置共用一套抽气装置，满足保鲜需求的同时最低限度的降低产品成本。采用三通接头或可控三通阀进行气路连接，结构简单，便于生产操作。抽气装置放置在压机舱内，减少对冰箱间室内容积的占用，尽可能的提高冰箱的容积率，同时降低抽气装置工作时的噪音。Further, at least two or more air-conditioning fresh-keeping devices share a set of air extraction devices, so as to meet the fresh-keeping requirements and at the same time reduce the product cost to a minimum. The three-way joint or the controllable three-way valve is used to connect the gas circuit, and the structure is simple, which is convenient for production and operation. The air extraction device is placed in the compressor cabin, which reduces the occupation of the interior volume of the refrigerator compartment, improves the volume ratio of the refrigerator as much as possible, and reduces the noise when the air extraction device works.
进一步地，本发明的冰箱中，因为具有透湿装置和涡流风机或离心风机，涡流风机或离心风机的进风口可朝向透湿膜，可加快气调保鲜装置外部空气流动，降低气调保鲜装置外侧湿度值，尤其是透湿膜外侧的湿度值，形成较大的湿度差，防止透湿膜效率降低或完全失效使保鲜空间内部水汽无法排出，提高透湿效率，进而降低食材产生的水汽在内部聚集形成凝露或者结霜，同时也可使储物间室内冷量尽快分布均匀，智能化、智慧化程度高。Further, in the refrigerator of the present invention, because there is a moisture permeable device and a vortex fan or a centrifugal fan, the air inlet of the vortex fan or centrifugal fan can face the moisture permeable film, which can speed up the air flow outside the air-conditioning fresh-keeping device and reduce the air flow rate of the air-conditioning fresh-keeping device. The external humidity value, especially the humidity value outside the moisture-permeable film, forms a large humidity difference, preventing the efficiency of the moisture-permeable film from being reduced or completely ineffective, so that the moisture inside the fresh-keeping space cannot be discharged, improving the moisture-permeability efficiency, and reducing the moisture generated by the ingredients.

进一步地，本发明的冰箱中，涡流风机或离心风机和让位凹槽的特殊布置形式，可使储物间室结构紧凑，布局合理，便于气流流动且噪音低，给人舒适的感觉。Further, in the refrigerator of the present invention, the special arrangement of the vortex fan or centrifugal fan and the recess can make the storage compartment compact in structure, reasonable in layout, convenient for airflow and low in noise, giving people a comfortable feeling.
进一步地，本发明的冰箱中，通过设置温控式导热装置，当泵头温度低时，利用电机产生的高温加热，防止泵头结霜结冰；泵头温度高时，热传递断开，防止电机上高温持续给泵头加温。可以减少或防止泵头处结霜结冰，保证真空泵性能，延长真空泵可靠性。泵出口连接排气管，冷空气通过排气管通过温度传导实现电机温度降低，高速空气通过排气管强制对流实现电机温度降低，通过延长排气总长度实现降噪。防止电机温度过高影响抽气装置的使用寿命，也可降低抽气装置产生的噪音，提高用户体验效果。温控式导热装置也可防止持续给泵头加温，影响电机的散热效果。Further, in the refrigerator of the present invention, by setting the temperature-controlled heat conduction device, when the temperature of the pump head is low, the high temperature generated by the motor is used to heat the pump head to prevent the pump head from frosting and freezing; when the temperature of the pump head is high, the heat transfer is disconnected, Prevent the high temperature on the motor from continuously heating the pump head. It can reduce or prevent frost and icing at the pump head, ensure the performance of the vacuum pump, and prolong the reliability of the vacuum pump. The pump outlet is connected to the exhaust pipe, the cold air is passed through the exhaust pipe to reduce the temperature of the motor through temperature conduction, the high-speed air is forced to convect through the exhaust pipe to reduce the temperature of the motor, and the total length of the exhaust is extended to achieve noise reduction. It can prevent the high temperature of the motor from affecting the service life of the air extraction device, and can also reduce the noise generated by the air extraction device and improve the user experience. The temperature-controlled heat-conducting device can also prevent the pump head from being heated continuously and affect the heat dissipation effect of the motor.

Each modified atmosphere membrane assembly 42 has at least one modified atmosphere membrane and an oxygen-rich gas collection cavity, and It is configured so that the oxygen in the air flow in the space around the modified atmosphere membrane assembly 42 is more permeable through the modified atmosphere membrane and enters the oxygen-enriched gas collection chamber relative to the nitrogen therein, so that the oxygen in the fresh-keeping space flows out of the fresh-keeping space more than the nitrogen. .
在本发明实施例中，因为具有至少两个以上的气调保鲜装置30，即具有至少两个以上的气调间室，每一个气调间室都有各自的气调膜组件42，并且每一个气调间室都有自己的温度值范围，实现不同食材的保鲜需求。In the embodiment of the present invention, because there are at least two or more air-conditioning fresh-keeping devices 30, that is, there are at least two or more air-conditioning compartments, each air-conditioning compartment has its own air-conditioning membrane assembly 42, and each air-conditioning compartment has its own air-conditioning membrane assembly 42.

Also for example, the suction port is in controlled communication with the plurality of oxygen-enriched gas collection chambers through a control valve. At least two or more air-conditioning fresh-keeping devices 30 share a set of air extraction device 70, which can meet the fresh-keeping requirements and at the same time minimize product cost. A three-way joint or a controllable three-way valve 80 is used to connect the gas path, the structure is simple, and the production operation is convenient.
进一步地，箱体内部还设置有用于放置压缩机的压缩机仓，抽气装置70设置于压缩机仓内。Further, a compressor compartment for placing the compressor is also arranged inside the box, and the air extraction device 70 is arranged in the compressor compartment.
当位于压缩机仓内的抽气装置70进行工作时，当使用三通接头进行抽气控制时，同时对冷藏间室内的气调膜组件42及低温间室内的气调膜组件42同时进行抽气，并且工作时间根据冷藏室内的气调膜组件42和低温气调膜组件42中需要抽气时间较长的进行确定抽气时间，保证抽气质量，达到保鲜要求。当使用三通阀80进行抽气控制时，分别检测冷藏间室21内气调膜组件42抽气质量和低温室内气调膜组件42抽气质量，当达到要求时停止抽气。各个保鲜间室设置的温度不同，如冷藏间室21内的温度设置为5～8℃，有利于水果、蔬菜等的保鲜需求；低温间室如变温间室23内的温度设置为0～-3℃，有利于肉类、海鲜等食材的保鲜需求。When the air extraction device 70 located in the compressor compartment is working, when using the tee joint for air extraction control, the air control membrane module 42 in the refrigerating compartment and the air conditioning membrane module 42 in the low temperature compartment are simultaneously pumped. air, and the working time is determined according to the air-conditioning membrane assembly 42 in the refrigerating room and the low-temperature air-conditioning membrane assembly 42 which require a longer air extraction time to ensure the air extraction quality and meet the fresh-keeping requirements. When the three-way valve 80 is used for air extraction control, the air extraction quality of the controlled atmosphere membrane assembly 42 in the refrigerating compartment 21 and the air extraction quality of the controlled atmosphere membrane assembly 42 in the low temperature room are respectively detected, and the air extraction is stopped when the requirements are met.

The air-conditioning fresh-keeping device 30 defines a fresh-keeping space, and the rear portion of the upper surface of the air-conditioning fresh-keeping device 30 is provided with a communication port. The moisture-permeable device 41 can be installed in the communication port, and the moisture-permeable device 41 has a moisture-permeable film, so that the moisture can flow in one direction, and when the humidity in the fresh-keeping space is greater than the humidity outside the fresh-keeping space, the moisture in the fresh-keeping space can pass through the permeable membrane. The wet film flows out of the fresh-keeping space. That is to say, the moisture-permeable membrane allows the moisture in the fresh-keeping space to permeate unidirectionally to the outside of the fresh-keeping space through the moisture-permeable membrane, so that the fresh-keeping space has the required humidity.

在本发明的一些实施例中，冰箱还可包括湿度检测装置，湿度检测装置配置成检测保鲜空间内的湿度和/或保鲜空间外且处于储物间室内的湿度。涡流风机50或离心风机配置成根据湿度检测装置检测到的湿度值启动。例如，湿度检测装置包括第一湿度检测装置和第二湿度检测装置。第一湿度检测装置设置于保鲜空间内，检测保鲜空间内的湿度得到第一湿度值。第二湿度检测装置设置于保鲜空间外且处于储物间室内，检测保鲜空间外且处于储物间室内的湿度得到第二湿度值。涡流风机50或离心风机可配置成在第一湿度值和第二湿度值之间的差值小于或等于第一预设值时开启，直至第一湿度值和第二湿度值之间的差值小于第二预设值时关闭。第二预设值小于第一预设值。In some embodiments of the present invention, the refrigerator may further include a humidity detection device configured to detect humidity in the fresh-keeping space and/or humidity outside the fresh-keeping space and in the storage compartment. The eddy current fan 50 or the centrifugal fan is configured to be activated according to the humidity value detected by the humidity detection device. For example, the humidity detection device includes a first humidity detection device and a second humidity detection device. The first humidity detection device is arranged in the fresh-keeping space, and detects the humidity in the fresh-keeping space to obtain a first humidity value. The second humidity detection device is arranged outside the fresh-keeping space and inside the storage compartment, and detects the humidity outside the fresh-keeping space and inside the storage compartment to obtain a second humidity value. The vortex fan 50 or centrifugal fan may be configured to be turned on when the difference between the first humidity value and the second humidity value is less than or equal to the first preset value, until the difference between the first humidity value and the second humidity value It is turned off when it is less than the second preset value. The second preset value is smaller than the first preset value.
在具体使用时，判断第一湿度值和第二湿度值之间的差值是否大于第一预设值。若否，开启涡流风机50或离心风机，若是，不开启涡流风机50或离心风机。进一步地，继续判断第一湿度值和第二湿度值之间的差值是否小于第二预设值，第二预设值小于第一预设值。若是，关闭涡流风机50或离心风机。否则继续使涡流风机50或离心风机保持运转状态。根据第一湿度值和第二湿度值之间的差值控制涡流风机50或离心风机的开启，透湿装置41在进行水分单向渗透工作时，保鲜空间内的湿度逐渐降低，外部的湿度逐渐升高，两者之间的差值越来越小，直至小于或等于第一预设值时，涡流风机50或离心风机开启，提高透湿效率。进一步地，保鲜空间内的湿度再次逐渐降低，外部的湿度在涡流风机50或离心风机的作用下先降低，后在降低的基础不变、降低或升高速率降低，最终使得保鲜空间内外的差值越来越小，当保鲜空间内的湿度与外侧的湿度之间的差值较小时，可认为保鲜空间内的湿度变低，满足要求，内外之间的差值不足以使透湿装置41工作，涡流风机50或离心风机停机，节能。In specific use, it is determined whether the difference between the first humidity value and the second humidity value is greater than the first preset value. If not, turn on the eddy current fan 50 or the centrifugal fan, if so, do not turn on the eddy current fan 50 or the centrifugal fan. Further, continue to determine whether the difference between the first humidity value and the second humidity value is less than a second preset value, and the second preset value is less than the first preset value. If so, turn off the vortex fan 50 or the centrifugal fan. Otherwise, continue to keep the vortex fan 50 or the centrifugal fan running. The turning on of the vortex fan 50 or the centrifugal fan is controlled according to the difference between the first humidity value and the second humidity value. When the moisture permeable device 41 performs the one-way infiltration of moisture, the humidity in the fresh-keeping space gradually decreases, and the external humidity gradually decreases. When the value increases, the difference between the two becomes smaller and smaller until it is less than or equal to the first preset value, and the vortex fan 50 or the centrifugal fan is turned on to improve the moisture permeability efficiency. Further, the humidity in the fresh-keeping space gradually decreases again, and the external humidity first decreases under the action of the eddy current fan 50 or the centrifugal fan, and then remains unchanged on the basis of reduction, and the decrease or increase rate decreases, finally making the difference between the inside and outside of the fresh-keeping space. The value is getting smaller and smaller, when the difference between the humidity in the fresh-keeping space and the humidity outside is small, it can be considered that the humidity in the fresh-keeping space becomes lower and meets the requirements, and the difference between the inside and outside is not enough to make the moisture permeable device 41 When working, the vortex fan 50 or the centrifugal fan stops to save energy.
需要注意的是，因为某种原因，例如储物间室内的湿度突然变大时，此时涡流风机50或离心风机可能处于关闭状态，若判断第一湿度值和第二湿度值之间的差值小于第一预设值，甚至小于第二预设值时，均要先开启涡流风机50或离心风机，涡流风机50或离心风机开启之后，保鲜空间外部湿度值明显降低，保证透湿装置41的透湿效率。可选地，为了进一步提高控制精确性，防止保鲜空间内外湿度都比较大的情况引起的误操作，在判断第一湿度值和第二湿度值之间的差值是否小于第二预设值时，还要判断第一湿度值是否大于预设湿度值；在第一湿度值和第二湿度值之间的差值小于第二预设值，其第一湿度值小于或等于预设湿度值时，关闭涡流风机50或离心风机。It should be noted that, for some reason, for example, when the humidity in the storage room suddenly increases, the vortex fan 50 or the centrifugal fan may be turned off at this time. If the difference between the first humidity value and the second humidity value is judged, When the value is smaller than the first preset value, or even smaller than the second preset value, the eddy current fan 50 or the centrifugal fan must be turned on first. After the eddy current fan 50 or the centrifugal fan is turned on, the external humidity value of the fresh-keeping space is significantly reduced, ensuring that the moisture permeable device 41 moisture permeability. Optionally, in order to further improve the control accuracy and prevent misoperation caused by the situation that the humidity inside and outside the fresh-keeping space is relatively high, when judging whether the difference between the first humidity value and the second humidity value is less than the second preset value , and also determine whether the first humidity value is greater than the preset humidity value; when the difference between the first humidity value and the second humidity value is less than the second preset value, and the first humidity value is less than or equal to the preset humidity value , turn off the vortex fan 50 or the centrifugal fan.
