Description

Fan cover and refrigerator comprising same

Technical Field

The utility model relates to the technical field of refrigeration transport tools, in particular to a fan cover and a refrigerator comprising the fan cover.

Background

The refrigerator is a device capable of adjusting the temperature in the refrigerator, and a refrigerating system is formed by a compressor, an evaporator arranged in the refrigerator, and the like. When the air in the refrigerator flows through the evaporator, the water vapor in the air condenses on the evaporator shell to form condensed water due to the low temperature of the evaporator. If the condensed water drops onto other parts or storage in the refrigerator, ice formation, part damage or storage deterioration may be caused, and thus it is necessary to collect the condensed water and drain it using a water collecting device. In particular, in the case of medical refrigerators, medical products such as medicines, vaccines, blood products and the like are stored in the medical refrigerator, and the temperature in the refrigerator is required to be maintained between 2 ℃ and 8 ℃. To maintain the temperature within the case, medical freezers are typically of air cooled design, with the evaporator typically being an overhead fin evaporator and equipped with a fan and fan housing. In addition, the evaporation capacity of the evaporator is generally designed to be high, and the size of the fin evaporator is large, so that the problems of collecting and discharging condensed water are particularly remarkable.

In the refrigerator structure, corresponding parts of the fan cover and the refrigerator shell form an air channel for air flow circulation, the evaporator and the water receiving disc are arranged in the air channel space, and the evaporator is positioned above the water receiving disc so as to be beneficial to condensed water to fall into the water receiving disc. The box body assembling and installing process comprises the following steps: firstly, an evaporator and a water receiving disc are installed, and finally, a fan cover is installed. Because the air duct space is narrow and small, the connection and the installation of the water receiving disc and the fixing site are difficult. In addition, the water pan is independently arranged in the air duct, once the connection between the water pan and the fixing site is loosened or falls off, the water pan is caused to fall off or shift, and then condensed water is leaked, so that articles stored in the refrigerator are damaged.

Fig. 1 is a schematic view of a front portion of a fan housing according to an embodiment of the present utility model, fig. 2 is a schematic view of a rear portion of a fan housing according to an embodiment of the present utility model, and fig. 3 is a schematic plan view of a fan housing according to an embodiment of the present utility model. A fan guard 100 according to an embodiment of the present utility model is described below with reference to fig. 1 to 3, and includes:

the fan installation part 10, the fan installation part 10 is designed to install the circulating fan, and the fan installation part 10 is provided with an air inlet; a water receiving part 20, the water receiving part 20 being located below the condenser for receiving water condensed on the condenser 30 and falling down; the fan mounting part 10 and the water receiving part 20 are integrally formed. The fan housing 100 may be made of Polycarbonate (Polycarbonate), acrylonitrile Butadiene Styrene (ABS), or other similar plastics, however, the fan housing 100 may also be made of metal to obtain better mechanical properties. In the specific embodiment shown in fig. 1 and 2, the fan cover has a structure including a bottom plate and four side plates surrounding the bottom plate, three bases for installing the fan are provided at the fan installation portion, and air inlet holes are provided at corresponding positions on the bottom plate.

The fan cover of the embodiment of the utility model is provided with the fan installation part and the water receiving part which are integrally structured, when the refrigerator is assembled, the circulating fan is firstly installed on the fan installation part of the fan cover, and then the fan cover is integrally installed at the corresponding position of the shell (the water receiving part is arranged below the condenser), so that the installation difficulty of limited operation space when the water receiving disc is independently installed in a narrow air duct space is avoided. Meanwhile, the fan cover of the fan installation part and water receiving part integrated structure is integrally installed, the falling or shifting situation is reduced, and even if the falling or shifting situation is also easy to find and maintain.

Because the temperature at the condenser position is lower than the temperature of the air in the refrigerator, the water vapor in the air is easy to condense at the condenser position, and the condensed water falls to the water receiving part of the fan cover under the action of gravity. For a refrigerator which needs to be used for a long time, the condenser needs to be operated for a long time, so that water in the water receiving part is gradually accumulated and increased, and condensed water needs to be discharged. As shown in fig. 2 and 3, the water receiving portion 20 is provided with at least one drain nozzle 70 at a side remote from the blower mounting portion 10. In this embodiment, the number of the drain nozzles is one, and a person skilled in the art can design a suitable number of drain nozzles according to the drain requirement of the condensate water. The drain pipe is communicated with the drain nozzle, and finally the condensed water is discharged to the outside of the refrigerator.

In one embodiment as shown in fig. 4, the water receiving portion 20 includes a bottom plate 21 of a substantially flat plate structure, and the bottom plate 21 is provided in an inclined structure gradually lowered from near the blower mounting portion 10 toward the drain nozzle 70. According to the above configuration, the condensed water falling onto the water receiving portion flows by gravity in the direction of the drain nozzle 70 by the fan mounting portion 10, flows into the drain nozzle, and is discharged through the drain pipe. The arrows shown in fig. 4 indicate the direction of air flow in the refrigerator, and due to the operation of the circulation fan, air enters the circulation duct through the air inlet hole from the storage space surrounded by the housing below the fan cover, flows in the circulation duct toward the air outlet end, flows further to the air outlet and reenters the storage space. The bottom plate of the water receiving part is of an inclined structure, so that the condensed water can be conveniently collected and discharged.

In the fan cover according to the above embodiment of the present utility model, the circulating fan corresponds to the upper portion of the fan mounting portion, and the condenser corresponds to the upper portion of the water receiving portion, and although in theory, condensed water condensed at the condenser portion may fall to the water receiving portion and flow to the drain outlet, when the refrigerator is not placed in the required placement direction, the condensed water of the water receiving portion may flow to the fan mounting portion, thereby causing damage to the circulating fan provided in the fan mounting portion when encountering water. Further improvements to the above embodiment are provided with a water deflector 40 between the fan mounting portion 10 and the water receiving portion 20. The height of the water deflector is preferably 10 to 30 mm. Referring to the schematic cross-section of the fan cover shown in fig. 5, the space above the fan cover and the shell form a circulating air channel together, the water baffle is arranged in the circulating air channel, the height of the water baffle cannot be set too high, and the water baffle is prevented from influencing the air flow circulation in the circulating air channel. The water baffle may be an independently provided structure, and after the processing is completed in other portions than the water baffle, the water baffle is connected between the fan mounting portion and the water receiving portion by means of bonding or welding or the like in a suitable manner. The water baffle may be made of Polycarbonate (Polycarbonate), acrylonitrile-butadiene-styrene (ABS), or other plastic with similar properties, or may be made of metal to obtain better mechanical properties.

Because the fan cover of the embodiment of the utility model is provided with the water receiving part, the condensed water falling from the condenser falls to the water receiving part and is received by the water receiving part. Therefore, the fan cover needs to have higher strength, so that the problems of deformation and the like in the using process are avoided, and condensate water leakage is caused. In a further improved embodiment, as shown in fig. 1, the fan guard further comprises a reinforcing rib 60, on which through holes 61 for the circulation of condensate water are provided. The reinforcing ribs may be of an independent structure, and are connected between the fan mounting portion and the water receiving portion by bonding or welding or the like in a suitable manner after the other portions except the water blocking plate are finished. The reinforcing ribs may also be integrally formed with other parts of the fan housing, and the reinforcing ribs may be made of Polycarbonate (Polycarbonate), acrylonitrile-butadiene-styrene (ABS), or other plastics with similar properties, and of course, the reinforcing ribs may also be made of metal to obtain better mechanical properties.

When air flows in the circulating air duct towards the air outlet end direction, the direction change occurs at the connection position of the top plate and the back plate of the shell of the cuboid structure, and the change of the air flowing direction is not facilitated because the position is of a right-angle structure. In a preferred embodiment, the upper part of the fan installation part 10 of the fan cover is an air inlet end, and the upper part of the water receiving part 20 of the fan cover is an air outlet end; as shown in fig. 1, 2 and 5, an air deflector 50 is further disposed at the air outlet end, and the air deflector 50 is used for guiding the air flow to the air outlet located at the side of the water receiving part.

The structure of the housing may be a suitable structure for storing the required transported articles, for example, a rectangular or square housing may be made of Polycarbonate (Polycarbonate), acrylonitrile Butadiene Styrene (ABS), or other similar plastics, and of course, the water baffle may be made of metal to obtain better mechanical properties. The circulating air duct is composed of a shell and a fan cover, and for a shell with a cuboid structure, the circulating air duct comprises a top plate of the shell, a bottom plate of the shell, a back plate of the shell, a front panel of the shell and side plates of the two shells. The fan cover is of a structure comprising a bottom plate and four side plates surrounding the bottom plate, the fan cover with the structure is arranged in a shell with a cuboid structure, the bottom plate corresponds to a top plate of the shell, one side plate corresponds to a back plate of the shell, and a circulating air channel is formed by the top plate of the shell, the bottom plate of the fan cover and one side plate; the air outlet is composed of a side plate and a back plate of the shell, and is positioned at the side of the water receiving part (the air outlet is far away from the fan installation part).

The height of the water deflector is preferably 10 to 30 mm.

Because the temperature at the condenser position is lower than the temperature of the air in the refrigerator, the water vapor in the air is easy to condense at the condenser position, and the condensed water falls to the water receiving part of the fan cover under the action of gravity. For a refrigerator which needs to be used for a long time, the condenser needs to be operated for a long time, so that water in the water receiving part is gradually accumulated and increased, and condensed water needs to be discharged.
