[0014] Next, embodiments of the present invention will be described with reference to the attached drawings to facilitate understanding of the present invention. Note that parts not relevant to the description may be omitted from the drawings.

[0015] A cooling device 10 according to one embodiment of the present invention is, for example, a freezer or refrigerator, and as shown in FIG. 1(B), is equipped with a fan 20, a cooling coil 30, a deflection section 40, a drainage section 50, and heaters 60a to 60e (see FIG. 3(B)), and can refrigerate or freeze items to be cooled, such as food ingredients, stored in space S inside the refrigerator.

[0016] A plurality of fans 20 are disposed adjacent to each other above the space S and can blow air downward.

[0017] As shown in Figures 2(A) and (B), the cooling coil 30 is disposed below the fan 20 and can cool the air it comes into contact with. The air sent from the fan 20 is cooled as it passes through the cooling coil 30 and is exhausted downward inside the refrigerator as cooled air. The cooled air also exhausts to the front and rear as shown by the arrows in Figure 2(B).

[0018] The deflection unit 40 has a plurality of deflection members 402a to 402e. Each of the plurality of deflection members 402a to 402e is disposed below the cooling coil 30 and above the space S (see FIG. 1(B)) in which the object to be cooled is stored, and can change the direction of the cooling air that has passed through the cooling coil 30 and can function as a receiver for receiving defrost water.

[0019] Each of the deflection members 402a to 402e is a rod-shaped metal member extending in one direction and has substantially the same shape. As shown in Fig. 2(A) and Fig. 3(A), one end side of each of the deflection members 402a to 402e is disposed so as to be lower than the other end side. As shown in FIG. 3C, the deflection members 402a to 402e are arranged side by side with no gap between them, with the edge portions of the deflection members 402a to 402e overlapping with the adjacent deflection members 402a to 402e in plan view.

[0020] Each of the deflection members 402a to 402e has a thin plate-like louver portion 404 disposed at an angle to the direction of the flow of the cooling air so that the height position gradually decreases from the front side to the rear side, as shown in Fig. 4. A flow path forming groove 403 that serves as a flow path for flowing defrost water is formed on the upper surface of the lower end of the louver portion 404. The flow path forming groove 403 is formed by bending the edge of the louver portion 404 upward. The cooling air whose direction has been changed by the louver portion 404 passes between adjacent deflection members and flows rearward and downward (see the arrow shown in FIG. 2(B)).

[0021] The direction of deflection of the cooling air may be, for example, downward toward the front, downward toward the left, or downward toward the right, as long as it is at least downward. In other words, it is sufficient that the flow of the cooling air after passing between the deflection members 402a to 402e includes at least a downward vector component. Additionally, the deflection direction can be changed by changing the orientation in which the deflection members 402a to 402e are attached.

[0022] As shown in FIG. 3(A), the drainage section 50 has a drainage member 502 and a drain pipe 504, and can receive the defrosted water flowing out from each of the deflection members 402a to 402e and discharge it to the outside. The drainage member 502 is a rod-shaped metal member that extends intersecting with the deflection members 402a-402e, and is located below one end of the deflection members 402a-402e to support the one end. The drainage member 502 is formed with a drain groove that serves as a flow path for the defrost water flowing out from one end of the deflection members 402a-402e. One end of the drain pipe 504 is connected to the drain groove of the drain member 502, and the other end extends to the outside of the cooling device 10. The drain pipe 504 can discharge the defrosted water flowing through the drain groove to the outside.

[0023] The heaters (an example of a heating means) 60a to 60e are, for example, waterproof cord heaters, and as shown in FIG. 3(B), are provided along the longitudinal direction on the underside (rear side) of the louver portion 404 of each deflection member 402a to 402e, and can prevent the defrost water flowing through the flow path forming groove 403 from freezing. Heaters (not shown) are also provided in the drainage member 502 and the drain pipe 504 through which defrosted water flows and which may freeze. Each heater may be any heating means capable of suppressing freezing of the defrost water.

[0024] As shown in FIG. 1(A), a door 102 is provided on the front side of the cooling device 10, and objects to be cooled are carried in and out of the interior of the refrigerator through this door 102. Also, on the front side, a control panel 104 for controlling the fan 20 and other components required for cooling is provided.

[0025] Next, the operation of the cooling device 10, particularly the operation for removing frost from the cooling coil 30, will be described. To We will explain about this.

[0026] During a cooling operation for cooling an object to be cooled, the fan 20 rotates, and the cooling air flows downward after passing through the cooling coil 30. The cooling air has its flow direction changed by passing through the deflection members 402a to 402e, and flows rearward and downward. Therefore, the flow of cooling air is prevented from being significantly obstructed.

[0027] On the other hand, as the cooling operation continues, frost gradually forms on the cooling coil 30. When the cooling operation continues for a long period of time and a large amount of frost forms on the cooling coil 30, a defrosting operation is performed by the user of the cooling device 10 to remove the frost.

[0028] When the defrosting operation is performed, the fan 20 is stopped and the cooling coil 30 is heated. As a result, the frost adhering to the cooling coil 30 melts and falls as defrosted water. The falling defrosted water is received by deflection members 402a to 402e provided below the cooling coil 30.

[0029] Here, as shown in FIG. 3(C), the deflection members 402a to 402e are arranged without any gaps in plan view, so that the defrost water is prevented from dropping below the deflection members 402a to 402e and adhering to the object to be cooled. The defrosted water that falls on the deflection members 402a to 402e flows into the flow path forming grooves 403 (see FIG. 4), and then flows toward the end portion located at a lower position. The defrosted water further flows into the drainage member 502, and is discharged from the drain pipe 504 to the outside.

[0030] During the defrosting operation, the heaters 60a to 60e generate heat, thereby heating the deflection members 402a to 402e. In addition, a heater (not shown) also heats the drainage member 502 and the drain pipe 504. This prevents the defrost water from freezing and clogging the flow path, resulting in overflow.

[0031] As described above, the cooling device 10 suppresses adhesion of defrosted water to the object to be cooled during the defrosting operation.

[0032] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment, and all changes in conditions that do not depart from the gist of the present invention are within the scope of application of the present invention. The cooling device according to the above-described embodiment is not limited to a freezer or a refrigerator, and may be configured as a freezer warehouse. [Explanation of symbols]
