Detailed Description
The present invention provides a refrigerating and freezing apparatus, fig. 1 is a schematic structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 2 is a partial structural view of a refrigerating and freezing apparatus according to an embodiment of the present invention.
Referring to fig. 1 and 2, the refrigerating and freezing apparatus 1 of the present invention may generally include a cabinet 10, a door, and a storage device 30. The cabinet 10 defines therein a storage compartment 11 for storing articles and an evaporator compartment 12 housing an evaporator 20. The door body is disposed at a front side of the cabinet 10 to selectively open or close the storage compartment 11, so that a user can take and place articles. The storage device 30 is disposed in the storage compartment 11, and a fresh space 31 is defined therein. Specifically, the storage compartment 11 may be a refrigeration compartment having a refrigeration storage environment, or may be a temperature-changing compartment having a variable storage environment, or another suitable storage compartment. In addition to the storage compartment 11, other storage compartments, such as a freezing compartment, may be defined in the cabinet 10.
In particular, the refrigeration freezer 1 further includes a moisture conditioning assembly 40 and a dehumidifying assembly. FIG. 3 is a schematic exploded view of a storage device and associated structures according to one embodiment of the present invention. Referring to fig. 3, the moisture regulating assembly is installed in the storage device 30 and has at least one moisture permeable film 41 and one moisture collecting chamber 42, and both sides of the moisture permeable film 41 are exposed to the moisture collecting chamber 42 and the fresh food space 31, respectively, to allow moisture in the fresh food space 31 to permeate to the moisture collecting chamber 42. The dehumidifying assembly has a dehumidifying fan 51 disposed in the moisture collecting chamber 42 and a dehumidifying pipe 52 connected between the moisture collecting chamber 42 and the evaporator chamber 12 to promote the moisture in the moisture collecting chamber 42 to flow to the evaporator chamber 12 by the dehumidifying fan 51.
The refrigerating and freezing apparatus 1 of the present invention is particularly provided with a moisture conditioning assembly 40 and a dehumidifying assembly. The moisture regulating member 40 has at least one moisture permeable film 41 and one moisture collecting chamber 42, and both sides of the moisture permeable film 41 are respectively exposed to the moisture collecting chamber 42 and the fresh-keeping space 31 in the storage device 30, that is, the moisture collecting chamber 42 and the fresh-keeping space 31 in the storage device 30 are communicated through the moisture permeable film 41. When the humidity in the fresh-keeping space 31 is high, moisture in the fresh-keeping space permeates through the moisture permeable film 41 to the moisture collecting chamber 42, so that the humidity of the air in the moisture collecting chamber 42 is high. The high-humidity air in the moisture collection chamber 42 is discharged into the evaporator chamber 12 through the dehumidifying line 52 by the driving action of the dehumidifying fan 51, and contacts with the evaporator 20 in the evaporator chamber 12, and the moisture in the high-humidity air is condensed on the evaporator 20, thereby achieving the purpose of dehumidification. The water condensed on the evaporator 20 is discharged out of the case 10 through the drain pan when the evaporator 20 is defrosted, thereby preventing the generation of condensation inside the case 10. The high humid air in the moisture collecting cavity 42 is continuously discharged, and the influence on the moisture permeability of the moisture permeable film 41 caused by the overhigh humidity in the moisture collecting cavity 42 is avoided, so that the moisture in the fresh-keeping space 31 can be continuously permeated into the moisture collecting cavity 42 and is continuously discharged, and the problem of overhigh humidity in the storage device 30 is effectively avoided.
At the same time, due to the driving action of the dehumidifying fan 51, even if the dehumidifying pipe 52 having a relatively long path is provided between the moisture collecting chamber 42 and the evaporator chamber 12, it is ensured that the high-humidity air in the moisture collecting chamber 42 can be promptly and quickly discharged toward the evaporator chamber 12.
Specifically, the selection of the moisture permeable film 41 may be matched with the range of humidity in the fresh keeping space 31. For example, the moisture permeability of the moisture permeable film 41 may be set to allow moisture in the fresh food space 31 to permeate through the moisture permeable film 41 to the moisture collecting chamber 42 when the humidity in the fresh food space 31 is higher than a preset maximum humidity threshold. When the humidity in the fresh-keeping space 31 is higher than the preset maximum humidity threshold, the moisture in the fresh-keeping space 31 cannot permeate the moisture permeable film 41 to the moisture collecting cavity 42.
In some embodiments, the refrigerating and freezing device 1 further includes a humidity sensor disposed in the storage device 30 for acquiring the humidity in the fresh-keeping space 31. The dehumidifier fan 51 is configured to be controlled activated when the humidity in the fresh space 31 is above a preset maximum humidity threshold. That is, when the moisture in the fresh keeping space 31 permeates through the moisture permeable film 41 to the moisture collecting chamber 42, the dehumidifying fan 51 is activated to timely exhaust the moisture in the moisture collecting chamber 42, so as to prevent the moisture from being excessively accumulated in the moisture collecting chamber 42 to affect the moisture permeability of the moisture permeable film 41.
Specifically, the preset maximum humidity threshold may be any relative humidity value between 90% and 98%.
In some embodiments, the storage device 30 has a first hollow portion 32 formed at the top thereof, and the moisture regulating assembly 40 is disposed in the first hollow portion 32. The moisture regulating assembly 40 further includes a first cover 43 covering the first cutout 32 from outside the storage device 30 to define a moisture collection chamber 42 between the first cover 43 and the first cutout 32. When the drawer fan 51 is in the stopped state, the moisture collecting cavity 42 is in the sealed state, and therefore, the fresh-keeping space 31 in the storage device 30 is also in the relatively sealed state, which is beneficial to maintaining the humidity in the fresh-keeping space 31, thereby being beneficial to the fresh-keeping storage of food materials.
Specifically, the first hollow portion 32 may include a plurality of fine through holes densely arranged.
In some embodiments, the first housing 43 has a first communication hole 431 formed therein, the side wall of the evaporator chamber 12 has a second communication hole 121 formed therein, and the dehumidifying pipe 52 is sealingly connected between the first communication hole 431 and the second communication hole 121. Thus, when the moisture exhaust fan 51 is operated, the high-humidity air in the moisture collection chamber 42 flows into the moisture exhaust pipe 52 from the first communication hole 431, flows along the moisture exhaust pipe 52 to the second communication hole 121, and enters the evaporator chamber 12 through the second communication hole 121 to contact the evaporator 20. Since the dehumidifying pipe 52 is hermetically connected to both the first and second communication holes 431 and 121, there is no leakage problem of the high humidity air during the flow process, and the problem of undesirable frost formation in other areas is avoided.
Further, the second communication hole 121 is located at a height in the middle or lower portion of the evaporator 20. Therefore, the high-humidity air flowing to the evaporator chamber 12 through the second communication hole 121 can contact with the middle area or the middle lower area of the evaporator 20, and the high-humidity air can be fully contacted with the evaporator 20, so that the moisture in the high-humidity air can be effectively condensed on the evaporator 20, and the situation that the air with higher humidity enters the storage chamber along with the cooling air flow to cause the higher humidity of the storage chamber to be unfavorable for storing food materials is avoided.
In some embodiments, the refrigeration freezer 1 further comprises a water storage tank 61 and a humidification assembly. The water storage tank 61 is used for storing water. The humidification subassembly is configured to be controlled when humidity in the fresh-keeping space 31 is less than the minimum humidity threshold value of predetermineeing to humidifying in the fresh-keeping space 31, has avoided the problem that humidity in the fresh-keeping space 31 is low excessively effectively, has ensured to keep suitable humidity in the fresh-keeping space 31, is favorable to the fresh-keeping of edible material to be stored.
Further, the humidifying assembly may include an ultrasonic atomizing device and a humidifying conduit 62. The ultrasonic atomization device is disposed in the water storage tank 61 and configured to generate water mist by ultrasonic vibration. A humidifying conduit 62 is connected between the water storage tank 61 and the fresh keeping space 31 for delivering the mist generated by the ultrasonic atomizing device to the fresh keeping space 31.
Further, a water storage tank 61 is provided adjacently above the storing device 30 so as to arrange a humidifying pipe 62 and the like. The rear side of the storing device 30 is provided with a third communication hole 33, one end of the humidifying pipeline 62 is hermetically communicated with the water storage tank 61, and the other end is hermetically communicated with the third communication hole 33.
In particular, the cold storage and refrigeration device 1 further comprises an ice maker, and the water storage tank 61 may be a water tank for supplying water to the ice maker. That is, the present invention humidifies the fresh-keeping space 31 in the storage device 30 by using the water tank for supplying water to the ice maker, fully utilizes the original structure of the refrigerating and freezing device 1, does not need to additionally add a water tank, simplifies the structure, and reduces the cost.
In some embodiments, the refrigerated freezer 1 further comprises a modified atmosphere module 70 and a gas extraction module 80. The modified atmosphere module 70 is disposed on the storage device 30 and has at least one modified atmosphere film 71 and one oxygen-enriched gas collecting cavity 72, wherein two sides of the modified atmosphere film 71 are respectively exposed to the oxygen-enriched gas collecting cavity 72 and the fresh keeping space 31 to allow more oxygen in the fresh keeping space 31 to penetrate through the modified atmosphere film 71 and enter the oxygen-enriched gas collecting cavity 72 than nitrogen therein. The pumping assembly 80 is communicated with the oxygen-enriched gas collecting cavity 72 for pumping the gas in the oxygen-enriched gas collecting cavity 72 out of the storage device 30.
Specifically, after the air pumping assembly 80 pumps the air in the oxygen-enriched air collecting cavity 72, a negative pressure is formed in the oxygen-enriched air collecting cavity 72, so that the air in the fresh keeping space 31 on the other side of the modified atmosphere film 71 flows into the oxygen-enriched air collecting cavity 72, and a nitrogen-rich and oxygen-poor environment is formed in the fresh keeping space 31. The nitrogen-rich and oxygen-poor environment can reduce the aerobic respiration intensity of the fruits and vegetables, and simultaneously ensure the basic respiration of the fruits and vegetables, and the fruits and vegetables are subjected to anaerobic respiration, so that the aim of keeping the fruits and vegetables fresh for a long time is fulfilled. A large amount of nitrogen in the space can not reduce the cooling efficiency of the fruits, vegetables and other articles, and can improve the preservation effect of the fruits, vegetables and other articles.
Because the storage device 30 for realizing the freshness preservation by adopting the mode of adjusting the nitrogen-oxygen ratio has better sealing performance. Therefore, when a large amount of food materials such as fruits and vegetables are stored in the storage device 30, the humidity in the storage device 30 easily exceeds the maximum humidity threshold value most suitable for storing fruits and vegetables. Therefore, the solution of the present invention having the humidity control module 40 and the dehumidifying module is more suitable for the refrigerating and freezing device 1 having the air-conditioning membrane module 80, which can achieve the preservation effect at the cell level and does not cause the problem of condensation in the storage device 30.
Further, the air extraction assembly 80 may include an air extraction line 81 and an air extraction pump 82. The extraction pipe 81 communicates with a through hole provided in the oxygen-enriched gas collection chamber 72.
In some embodiments, the second hollow portion 34 is formed at the top of the storage device 30, and the air-conditioning membrane assembly 71 is disposed at the second hollow portion 34. The air-conditioning assembly 71 further comprises a second housing 73 covering the second hollow-out portion from the outside of the storage device 30, so as to define an oxygen-enriched gas collection chamber 72 between the second housing 73 and the second hollow-out portion 34. When the air exhaust assembly 80 is in a stop state, the oxygen-enriched gas collection cavity 72 is in a sealed state, so that the preservation space 31 in the storage device 30 is also in a relatively sealed state, which is beneficial to maintaining the nitrogen and oxygen concentration in the preservation space 31, and is beneficial to preserving and storing food materials.
Specifically, the second hollow portion 34 may include a plurality of fine through holes densely arranged.
Specifically, the suction pump 82 may be disposed in a compressor compartment located at the bottom of the tank 10, not occupying the storage space in the tank 10.
