Detailed Description
The present invention is to provide a refrigerating and freezing apparatus, fig. 1 is a schematic configuration diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention, fig. 2 is a schematic sectional view of a refrigerating and freezing apparatus according to an embodiment of the present invention, and fig. 3 and 4 are schematic sectional views of a partial structure of a refrigerating and freezing apparatus according to an embodiment of the present invention, taken along different sectional planes, respectively. Referring to fig. 1 to 4, the refrigerating and freezing device 1 of the present invention includes a cabinet 10, an evaporator 20, a blower fan 30, and a plurality of humidifying fins 40.
The cabinet 10 defines a storage compartment 11 for storing articles therein. In particular, the storage compartment 11 may be a refrigerated compartment having a refrigerated storage environment.
Further, the evaporator 20 has a heat exchange tube 21 for circulating a refrigerant therethrough and a plurality of heat exchange fins 22 arranged at intervals. The heat exchange fins 22 can increase the contact area with the air flow, thereby improving the heat exchange effect.
The supply air fan 30 is configured to selectively cause the air flow to circulate between the evaporator 20 and the storage compartment 11 during cooling of the storage compartment 11 and during non-cooling of the storage compartment 11. During the cooling of the storage compartment 11, the storage compartment 11 needs cooling airflow, and at this time, the air supply fan 30 is in an operating state to drive airflow to circularly flow through the evaporator 20 and continuously deliver the cooling airflow to the storage compartment 11. During periods when the storage compartment 11 is not refrigerated, the storage compartment 11 does not require cooling airflow to be refrigerated, and the conventional supply fan 30 is not operated at this time. However, the air supply fan 30 of the present invention may also be controlled to start operation during the period when the storage compartment 11 is not refrigerated, so that the air flow with relatively high temperature in the storage compartment 11 flows through the evaporator 20, and the frost on the evaporator 20 is melted.
The plurality of humidification sheets 40 are arranged along the arrangement direction of the plurality of heat exchange fins 22, and each humidification sheet 40 is arranged between two adjacent heat exchange fins 22 and is in contact with at least one heat exchange fin 22 so as to adsorb condensed water generated on the heat exchange fin 22. Each of the humidifying pieces 40 extends to the downstream side of the evaporator 20, so that at least part of the air flow passing through the evaporator 20 passes through the humidifying piece 40 and is sent to the storage compartment 11.
The refrigerating and freezing apparatus 1 of the present invention is particularly provided with a plurality of humidifying fins 40 arranged in the arrangement direction of the plurality of heat exchange fins of the evaporator, each of the humidifying fins 40 being disposed between two adjacent heat exchange fins 22 and being in contact with at least one of the heat exchange fins 22 to adsorb condensed water generated on the heat exchange fin 22. During cooling of the storage compartment 11, refrigerant flows through the evaporator 20, so that the temperature of the evaporator 20 is low, the airflow passing through it can be cooled, and moisture in the airflow can pre-cool and condense into water or frost on the evaporator 20 and even in the humidifying sheet 40. During the period of non-refrigeration of the storage compartment 11, the air supply fan 30 continuously operates, no refrigerant flows through the evaporator 20 at this time, the air flow with a relatively high temperature flowing circularly promotes the frost layer on the evaporator 20 and in the humidifying fins 40 to be melted into condensed water, and at least part of the condensed water on the heat exchange fins 22 is adsorbed and maintained by the humidifying fins 40, so that the air flow is humidified when the air flow flows through the humidifying fins 40, the humidity of the air flow flowing to the storage compartment 11 is increased, and the humidity of the storage compartment 11 is improved.
According to the refrigerating and freezing device 1, the air supply fan 30 is controlled to continuously operate during the non-refrigeration period of the storage chamber 11, the evaporator 20 can be defrosted through the air flow with relatively high temperature in the storage chamber 11, a defrosting heating wire is omitted, and the temperature in the storage chamber 11 is prevented from fluctuating. In addition, during the period when the storage compartment 11 is not cooled, part of the condensed water generated on the evaporator 20 is reasonably used for humidifying the storage compartment 11 through the humidifying sheet 40, so that a very complicated humidifying device is not required to be arranged, and the structure of the refrigerating and freezing device 1 is simplified.
More importantly, the humidifying pieces 40 are arranged between two adjacent heat exchange fins 22, so that on one hand, the humidifying pieces 40 are positioned on a flow path which is necessary to pass in the air flow flowing process, and the air flow is effectively humidified; on the other hand, the space of the heat exchange gap of the evaporator 20 is reasonably used for accommodating the humidifying sheet 40, the structure is more compact, and a special accommodating space for the humidifying sheet 40 does not need to be reserved independently, so that the original structure of the existing refrigerating and freezing device 1 does not need to be changed.
In some embodiments, the plurality of heat exchanger fins 22 are uniformly arranged at the same interval distance. That is, the distance between any two adjacent heat exchanging fins 22 is the same. The thickness of the humidifying sheet 40 is equal to the spacing distance between adjacent two heat exchange fins 22 so that the humidifying sheet 40 simultaneously contacts the two heat exchange fins 22 located at both sides thereof. On one hand, the heat exchange fins 22 can play a certain supporting and limiting role on the humidifying fins 40, so that the humidifying fins 40 which absorb water and become heavy are prevented from deforming; on the other hand, both the condensed water generated on the two heat exchange fins 22 can be adsorbed into the humidifying fins 40 located therebetween, increasing the amount of water held in the humidifying fins 40, thereby improving the humidifying effect.
In some embodiments, the evaporator 20 further includes a heat exchange tube 21 for circulating a refrigerant, and a plurality of heat exchange fins 22 are provided through the heat exchange tube 21. Specifically, the heat exchange tube 21 may extend in a serpentine, circuitous manner to extend the length thereof.
Further, a plurality of humidifying fins are disposed through a portion of the tube section of the heat exchange tube 21 to fix the lower section of the humidifying fins 40 through the heat exchange tube 21. That is, the lower section of the humidifying disc 40 may be fixed and restrained by the heat exchange pipe 21. Therefore, the humidifying sheet 40 can be more flat, so that condensed water can be adsorbed to the upper section of the humidifying sheet 40 more quickly, and the humidifying effect of the humidifying sheet 40 on the air flow is improved.
In some embodiments, the refrigerating and freezing apparatus 1 further includes a refrigerator group box 50, the refrigerator group box 50 is disposed at the bottom inside the cabinet 10 and defines the cooling chamber 12 therein, and the evaporator 20 is obliquely disposed inside the cooling chamber 12. That is, the cooling chamber 12 is disposed at the bottom, so as to avoid occupying the rear space of the storage compartment 11, and facilitate increasing the depth of the storage compartment 11.
Further, the humidifying fins 40 are in contact with the bottom ends of the heat exchange fins 22, and extend upward to an obliquely upper side of the evaporator 20. That is, the lower section of the humidifying fins 40 is in the heat exchange gaps between the heat exchange fins 22 to humidify the part of the air flow passing through the heat exchange gaps. Meanwhile, the upper section of the humidifying sheet 40 is at the downstream side of the evaporator 20 to humidify the air flow after passing through the evaporator 20. This can effectively increase the humidity of the air flow sent into the storage compartment 11.
Specifically, the cabinet 10 further defines an air supply duct 13 located behind the storage compartment 11, and the air supply fan 30 is provided in the cooling compartment 12 and located in front of the evaporator 20 to supply air to the evaporator 20. The evaporator 20 extends obliquely downward from front to rear, and the humidifying fins 40 are located at the rear upper side of the evaporator 20.
In some embodiments, the humidifying fins 40 extend up to the top wall of the refrigerator group cabinet 50, and the top of the humidifying fins 40 is fixed to the refrigerator group cabinet 50. That is, the top of the humidifying plate 40 can be fixed and limited by the refrigerating unit box 50, and thus, the whole humidifying plate 40 has at least two limiting points, which can make the humidifying plate 40 flatter and facilitate the condensed water to be adsorbed to the upper section of the humidifying plate 40 more quickly, thereby improving the humidifying effect of the humidifying plate 40 on the air flow.
Specifically, the top of the humidifying plate 40 may be fixed to the refrigerator group box 50 by gluing, pressing, or the like.
The applicant has recognized that in order to reduce the flow resistance of the air flow and reduce the cost, it is not necessary to provide one humidifying sheet 40 in each heat exchanging gap formed between two adjacent heat exchanging fins 22 of the evaporator 20. Therefore, it is necessary to optimize the humidification effect of each humidification sheet 40. However, the amount of condensed water formed on one or both of the heat exchange fins 22 is very limited, and it is difficult to ensure that a sufficient amount of condensed water can be adsorbed in each of the humidifying fins 40.
To this end, in some embodiments, the refrigerating and freezing device 1 further comprises a water pan 60, the water pan 60 being disposed below the evaporator 20 for collecting condensed water generated by the evaporator 20. The bottom of the humidifying plate 40 extends downward into the drain pan 60 to adsorb the condensed water in the drain pan 60. That is, the humidifying plate 40 may adsorb the condensed water in the water receiving tray 60 in addition to directly adsorbing the condensed water on the heat exchange fins 22, and even when there is not enough condensed water generated on the heat exchange fins 22, the water receiving tray 60 forms a main source of the humidifying water of the humidifying plate 40.
Further, a drain port 61 is provided in the bottom wall of the drain pan 60, and a drain pipe 62 for draining the condensed water in the drain pan 60 is provided at the drain port 61. An auxiliary pipe may be connected to the drain pipe 62 to drain the condensed water to an evaporation pan provided at the bottom of the cabinet 10. Applicants have recognized that the drain opening of existing drip trays is typically at its lowest point and that the drain pipe does not rise above the drain opening in order to drain all of the condensate water within the drip tray 60 in a timely manner. However, the present invention humidifies the storage compartment 11 by using the condensed water, and if a certain amount of condensed water is always maintained in the drain pan 60, the humidifying effect is better.
To this end, in the present invention, the end of the drain pipe 62 that is intended to meet the drain opening 61 extends towards the inside of the drip tray 60 to a position higher than at least part of the bottom wall of the drip tray 60 and lower than the top opening of the drip tray 60. That is, the drain pipe 62 is higher than the drain opening 61 and lower than the height of the top opening of the drip tray 60. When the amount of condensed water collected in the drip tray 60 is small and the water level is below the end of the drain pipe 62, the condensed water is not drained through the drain port 61 but is retained in the drip tray 60 to ensure that there is enough condensed water for humidifying the storage compartment 11. When the amount of the condensed water collected in the drip tray 60 is large and the water surface reaches the end of the drain pipe 62, the excessive condensed water is discharged through the drain pipe 62 and the drain port 61, so that the excessive overflow of the condensed water in the drip tray 60 is avoided.
Specifically, the drain pipe 62 may be integrally formed with the drip tray 60, i.e., the water inlet end of the drain pipe 62 is raised on the basis of the existing drip tray structure. The drain pipe 62 can also be connected with the water-receiving tray 60 in a sealing manner by welding, gluing or the like, that is, a ring of barrier is added around the drain opening 61 on the basis of the structure of the existing water-receiving tray, and the barrier and the downward extending drain pipe of the existing water-receiving tray form the drain pipe 62 of the utility model.
In some embodiments, the bottom wall of the drip tray 60 is formed with a V-shaped groove 63, and the bottom of the humidifying plate 40 abuts against the V-shaped groove 63. The V-shaped groove 63 is recessed downward so as to facilitate a certain amount of condensed water to be stored therein, and the humidifying plate 40 abuts against the V-shaped groove 63 so as to ensure that the humidifying plate 40 can adsorb the condensed water even if the amount of condensed water in the drip tray 60 is small.
In some embodiments, the humidifying element 40 may be a water-absorbing cotton or nonwoven fabric made of porous nonwoven fabric. The humidifying sheet 40 may have a single-layer structure, or may have a multi-layer structure stacked or adhered together.
It will be appreciated by those skilled in the art that the refrigerator-freezer 1 of the present invention may be a single door refrigerator and have only one storage compartment 11.
In other embodiments, the refrigerating and freezing device 1 may not be limited to the refrigerator structure shown in fig. 1, and may also be a double-door refrigerator, a triple-door refrigerator, or the like, and has a plurality of storage compartments arranged up and down, wherein the storage compartment 11 may be an upper storage compartment.
In other embodiments, the refrigerator 1 may not be limited to the refrigerator structure shown in fig. 1, but may also be a refrigerator or other various refrigerating and freezing devices that utilize air cooling to cool.
It should also be understood by those skilled in the art that the terms "upper", "lower", "front", "back", "top", "bottom", and the like used in the embodiments of the present invention are used with reference to the actual usage of the refrigeration and freezing apparatus 1, and these terms are only used for convenience of describing and understanding the technical solution of the present invention, and do not indicate or imply that the apparatus referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.
