A refrigerator, comprising a microfluidic testing system used for qualitatively or quantitatively testing a preset test parameter of a sample liquid. The microfluidic testing system comprises: a microfluidic biochip which is provided with a sample inlet, a communication port and a testing pool formed inside the microfluidic biochip, wherein the sample inlet, the testing pool and the communication port are in sequential communication by means of a micro-channel; a chip mounting mechanism used for mounting the microfluidic biochip; a sample liquid driving device in hermetic communication with the communication port, so as to promote the sample liquid in contact with the sample inlet to flow into the micro-channel and flow to the testing pool via the micro-channel; and a testing mechanism which is used for testing the testing pool to obtain the preset test parameter of the sample liquid.

Refrigerator

A refrigerator, comprising: a refrigerator body internally defining a storage space for storing articles, a door connected to the refrigerator body and used for opening and/or closing the storage space, and a microfluidic detection system which is provided on the door and comprises: a microfluidic biochip having a sample inlet, a communication port, and a detection pool formed in the microfluidic biochip, the sample inlet, the detection pool, and the communication port being connected in sequence by means of a microfluidic channel to allow a sample fluid in contact with the sample inlet to enter the microfluidic channel and flow into the detection pool by means of the microfluidic channel; and a detection mechanism used for detecting the detection pool after the sample fluid in the detection pool reacts with a detection reagent in the detection pool to obtain a preset detection parameter of the sample fluid.

The present invitation provides a rotatable storage rack, including a drawer, a storage rack body for slidingly receiving the drawer, and a sliding assembly disposed between the drawer and the storage rack body; wherein the sliding assembly includes a curved slide rail and a first pulley moving along the curved slide rail, the curved slide rail includes a horizontal section and a bent section, and the bent section is tangent to the horizontal section and arranged at an angle; when the first pulley moves along the horizontal section, the drawer is pulled out when the first pulley moves along the bent section, the drawer rotates downward.

Refrigerator, refrigerator door and rotatable storage rack

A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter an oxygen-rich gas collection chamber. An inlet end of the air pump is communicated with the oxygen-rich gas collection chamber in a controlled manner via a pipeline and a pipeline switching mechanism, for pumping gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that the actual content of oxygen in the freshness-keeping space is in a range of 2% to 19%.

The present invention provides a refrigeration and freezing device, including a case body, a door body, an oxygen-enrichment membrane assembly, an air pump, and a refrigeration system. For the refrigeration and freezing device, temperature within an appropriate storage range and a nitrogen-rich and oxygen-deficient atmosphere cooperate, thereby effectively extending the shelf life of foods.

Refrigeration and freezing device

A drawer assembly includes: drawers, arranged in a storage compartment of the refrigerator in a way of being capable of being pushed and pulled forward and rearward between a front extreme position and a rear extreme position; and two support assemblies in left-right parallel arrangement. Each of the support assemblies includes a support frame. The support frame is fixed to an inner wall of the storage compartment, is provided on an inner side with a first slideway extending forward and rearward, and is provided on a rear portion of the inner side with an elastic tongue. A left sidewall and a right sidewall of the drawer are respectively mounted on the first sideway of the support frame of one of the support assemblies in a forward and rearward slidable way.

Refrigerator and drawer assembly thereof

A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is provided with at least one air-conditioning membrane and an oxygen-rich gas collection chamber and configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter the oxygen-rich gas collection chamber. An air pump pumps gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that a ratio of the content of nitrogen in the freshness-keeping space to the content of oxygen in the freshness-keeping space is greater than 78/21.

Provided is a refrigerating and freezing device. The refrigerating and freezing device comprises a cabinet body with a first storage space defined therein, an oxygen-enriched membrane assembly and an air extraction device. A storage container in which an atmosphere-controlled freshness-keeping space is formed is disposed in the first storage space. The oxygen-enriched membrane assembly is provided with at least one oxygen-enriched membrane and an oxygen-enriched gas collection chamber. The air extraction device is communicated with the oxygen-enriched gas collection chamber through a pipeline to extract and discharge the gas that permeates into the oxygen-enriched gas collection chamber out of the storage container. The refrigerating and freezing device not only has good freshness-keeping performance, but also has relatively low requirements on the rigidity and strength of the storage container. Besides, it is small in size and low in noise, and it is suitable for household and individual use.

Refrigerating and freezing device

The present invention provides a refrigerator, comprising: an adsorption container, an air compressor and a nitrogen storage tank. A sealed storage space is formed in a storage compartment of the refrigerator. The adsorption container with carbon molecular sieves disposed therein is disposed in the storage compartment. The air compressor is directly connected to the adsorption container through an air inlet pipe and configured to supply compressed air for the adsorption container in a controlled manner so as to allow the carbon molecular sieves to prepare nitrogen by means of the compressed air. A gas inlet end of the nitrogen storage tank is connected to the adsorption container, and a gas outlet end thereof is communicated with the storage space.

The present invention provides a refrigerating and freezing device. A first sealed space and a second sealed space are disposed in a storage space inside the refrigerating and freezing device. The refrigerating and freezing device is further provided with a nitrogen generation device, which comprises an adsorption device and an air compressor that supplies compressed air for the adsorption device. The adsorption device utilizes the compressed air to prepare nitrogen that is provided for the first sealed space and an oxygen-enriched gas that is provided for the second sealed space. The freshness preservation capability of the first sealed space is improved. The bioactivity of food in the second sealed space is guaranteed.
