Detailed Description

The present invention first provides a refrigerating and freezing device, fig. 1 is a schematic structural view of a refrigerating and freezing device according to an embodiment of the present invention, fig. 2 is a schematic sectional view of a refrigerating and freezing device according to an embodiment of the present invention, fig. 3 is a schematic enlarged view of a part a in fig. 2, and a dotted arrow in fig. 2 indicates a general flow direction of an air flow. Referring to fig. 1 to 3, a refrigerating and freezing apparatus 1 of the present invention includes a box 10, an evaporator 20, a water receiving tray 30, and at least one air supply fan 40.

The cabinet 10 defines a storage compartment 11 for storing articles therein, and a cooling compartment 12 at the top inside the cabinet 10. That is, the cooling compartment 12 is placed on top, and therefore, structural members such as the evaporator 20 and the blower fan 40 can be placed on top, so that the space behind the console compartment 11 is prevented from being occupied, and the size of the console compartment 11 in the depth direction is enlarged.

An evaporator 20 is disposed within the cooling chamber 12 and is configured to cool an airflow passing therethrough. When refrigerant flows through the evaporator 20, the air flow passing through the evaporator 20 exchanges heat with the refrigerant in the evaporator 20, thereby absorbing the cold energy of the refrigerant and forming a cooling air flow.

The drip pan 30 is disposed under the evaporator 20 to collect condensed water generated from the evaporator 20. In particular, a gap 50 is formed between the drip tray 30 and the evaporator 20 to allow airflow therethrough. It will be appreciated that condensation collected within the drip tray 30 will naturally evaporate, which will cause the humidity in the gap 50 to be greater than in other areas.

At least one blower 40 is disposed in the cooling chamber 12 and is located at a side of the evaporator 20 in the horizontal direction to controllably cause the airflow in the storage compartment 11 to return to the storage compartment 11 through the evaporator 20 and the gap between the evaporator 20 and the drip tray 30.

The refrigerating and freezing apparatus 1 of the present invention forms a gap 50 allowing an air flow to pass through between the water receiving tray 30 and the evaporator 20, and arranges the air supply fan 40 at a side of the evaporator 20 in a horizontal direction. Therefore, when the air supply fan 40 is operated, the air flow in the storage compartment 11 can be caused to flow through the evaporator 20 and the gap between the evaporator 20 and the water receiving tray 30 and then return to the storage compartment 11. The air flow passing through the evaporator 20 exchanges heat with the evaporator 20 to form a cooling air flow, and the air flow passing through the gap between the evaporator 20 and the water-receiving tray 30 can accelerate volatilization of condensed water in the water-receiving tray 30 and carry away the volatilized condensed water, so that the air flow becomes a high-humidity air flow with high humidity. Therefore, the air flow sent to the storage chamber 11 is a mixed air flow of the cooling air flow and the high-humidity air flow, and the humidity in the storage chamber 11 is improved.

The utility model discloses rationally utilize the comdenstion water that evaporimeter 20 produced for 11 humidifications in storing room, and the humidification operation takes place at the normal circulation flow in-process of air current, has realized the automatic cycle humidification, does not increase any additional structure, also need not additionally design any control procedure, and the structure is very simple.

Fig. 4 is a schematic cross-sectional view of a water tray according to an embodiment of the present invention. In some embodiments, the bottom wall of the water-receiving tray 30 is opened with a water outlet 31, and a water outlet pipe 32 for draining the condensed water in the water-receiving tray 30 is disposed at the water outlet 31. An auxiliary pipe may be connected to the drain pipe 32 to drain the condensed water to an evaporation pan located 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 within the drip tray 30 in a timely manner. However, the utility model discloses utilize the comdenstion water for the humidification of storing compartment 11, if keep an amount of comdenstion water throughout in water collector 30, humidification effect can be better.

To this end, in the present invention, the end of the drain pipe 32 that is used to connect to the drain opening 31 extends into the drip tray 30 to a top opening that is higher than at least a portion of the bottom wall of the drip tray 30 and lower than the drip tray 30. That is, the drain pipe 32 is higher than the drain opening 31 and lower than the height of the top opening of the drip tray 30. When the amount of condensed water collected in the drip tray 30 is small and the water level is below the end of the drain pipe 32, the condensed water is not drained through the drain port 31 but is retained in the drip tray 30 to ensure that there is enough condensed water for humidifying the storage compartment 11. When the amount of the condensed water collected in the water pan 30 is large and the water surface reaches the end of the drain pipe 32, the excessive condensed water is discharged through the drain pipe 32 and the drain opening 31, so that the excessive overflow of the condensed water in the water pan 30 is avoided.

Specifically, the drain pipe 32 may be integrally formed with the drip tray 30, i.e., the water inlet end of the drain pipe 32 is raised on the basis of the existing drip tray structure. The drain pipe 32 can also be connected with the water pan 30 in a sealing manner by welding, gluing, etc., i.e. on the basis of the existing water pan structure, a circle is added around the water outlet 31 to form a baffle, and the baffle and the drain pipe extending downwards of the existing water pan form the drain pipe 32 of the present invention.

In some embodiments, the bottom wall of the drip tray 30 is inclined and the drain opening 31 opens at the lowermost bottom wall of the drip tray 30. Therefore, the condensed water dropped into the drain pan 30 is collected to the drain port 31, and the condensed water is discharged in time after the amount of the condensed water is accumulated to a certain degree.

The applicant has perceived that the evaporation and evaporation of the condensed water is very limited and the distribution of the evaporated moisture is also not controllable, resulting in a certain limitation of the humidification effect.

To this end, in some embodiments, the refrigerated refrigeration unit 1 further comprises a humidifying device 60, the humidifying device 60 being configured to adsorb condensed water in the water tray 30. That is, the humidifying device 60 can be in contact with the condensed water in the drain pan 30, and has the ability to adsorb and hold water.

Further, a partial section of the humidifying device 60 is located in the gap 50 between the evaporator 20 and the drip tray 30 to humidify the airflow passing through the gap 50. That is, the air flow passing through the gap 50 between the evaporator 20 and the drip tray 30 passes through a partial section of the humidifying device 60, thereby taking away the moisture held in the partial section. The partial section of the humidifying device 60 increases the distribution amount and the distribution area of the condensed water in the gap 50, thereby increasing the contact area of the air flow and the water and improving the humidifying effect.

In some embodiments, another partial section of the humidifying device 60 is located in the airflow path between the evaporator 20 and the storage compartment 11, so that at least part of the airflow passing through the evaporator 20 passes through the another partial section of the humidifying device 60 and then is sent to the storage compartment 11. That is, the airflow passing through the evaporator 20 passes through another section of the humidifying device 60, thereby carrying away the moisture retained in the other section. The other part of the section of the humidifying device further increases the distribution area of the condensed water, so that the contact area of the airflow and the water is further increased, and the humidifying effect is further improved.

It can be seen that, the utility model discloses a even refrigerating and freezing device 1 has increased humidification device 60, still is the natural circulation who utilizes the air current and flows the humidification that realizes storing compartment 11, and humidification process is very simple, can not increase refrigerating and freezing device 1's structural complexity and control burden.

Fig. 5 is a schematic structural view of an evaporator, a humidifying device and a water receiving tray in an assembled state according to an embodiment of the present invention. In some embodiments, referring to fig. 3 and 5, the humidifying device 60 comprises a first section 61, a second section 62 and a third section 63 connected in series.

The second section 62 is located in the gap 50 between the evaporator 20 and the drip tray 30 to humidify the airflow passing through the gap 50. The third section 63 is located in the airflow path between the evaporator 20 and the storage compartment 11, so that at least part of the airflow passing through the evaporator 20 passes through the third section 63 and then is sent to the storage compartment 11. That is, the third section 63 is located on the downstream side of the evaporator 20, and humidifies only the air flow flowing out of the evaporator 20, thereby preventing moisture in the humidified air flow from condensing on the evaporator 20, and effectively humidifying the storage compartment 11.

Further, the first section 61 may abut against the bottom wall of the drain pan 30 to ensure that the condensed water in the drain pan 30 is effectively adsorbed.

Further, the second section 62 extends obliquely straight from bottom to top toward the airflow direction. Thereby, the area of the second section 62 is increased, thereby increasing the contact area of the airflow with the water, and increasing the humidifying effect on the portion of the airflow that flows through the gap 50.

Specifically, the top of the second section 62 is at the same height as the bottom of the evaporator 20 or slightly higher than the bottom of the evaporator 20, so as to ensure that the airflow passing through the gap 50 between the evaporator 20 and the water pan 30 passes through the second section 62 completely, thereby increasing the amount of humidified airflow and further increasing the humidification effect of the compartment 11.

Further, the third section 63 extends from bottom to top in a plurality of bends along the airflow direction. Therefore, the area of the third section 63 can be increased as much as possible in a limited space, so that the contact area between the air flow passing through the evaporator 20 and the water is increased, the air flow humidified by the third section 63 is increased, and the humidification effect of the storage compartment 11 is improved.

Specifically, the humidifying device 60 may be a device having a good water-absorbing capacity, such as a water-absorbing cotton or a nonwoven fabric having a porous structure.

In some embodiments, the cooling chamber 12 is located above the storage compartment 11, and the cooling chamber 12 is separated from the storage compartment 11 by a partition 13, and the airflow inlet of the air supply fan 40 is directly communicated with the storage compartment 11 through a through hole formed in the partition 40. When the air supply fan 40 is operated, air is sucked from the storage compartment 11 and supplied toward the evaporator 20 and the gap 50, and the air flow passing through the evaporator 20 and the gap 50 is cooled and humidified and then conveyed into the storage compartment 11, so that the temperature and humidity in the storage compartment 11 are adjusted.

In some embodiments, the evaporator 20 is an elongated evaporator extending in a transverse direction of the cabinet 10. The number of the air supply fans 40 is two, the two air supply fans 40 are transversely arranged on the front side of the evaporator 20 side by side, and the bottom of the rear side of the cooling chamber 12 is provided with an air supply opening 14 communicated with the storage compartment 11. Because evaporimeter 20 is longer in horizontal ascending length, consequently, the utility model discloses a setting makes the air current flow through each heat transfer district section of evaporimeter 20 relatively evenly on horizontal two air supply fan 40 side by side, has improved the heat transfer effect between air current and the evaporimeter 20, and then has improved the temperature homogeneity in the storing room 11.
