Description

refrigerator

The present invention relates to a refrigerator, and particularly relates to a drainage structure.

Generally, a refrigerator generates cold air in a cooler chamber provided on the back side of the refrigerator body, and circulates the cold air in the refrigerator compartment by a cooling fan, thereby cooling foods in the refrigerator compartment. In addition, the amount of cold air supplied to the refrigerating compartment is adjusted by opening and closing the refrigerating compartment damper provided in the air path, and the temperature of the refrigerating compartment is adjusted by controlling the opening and closing of the refrigerating compartment damper.

The cold air flowing into the refrigerating compartment is distributed into the refrigerating compartment after passing through the air passage in the refrigerating compartment duct provided on the back side of the refrigerating compartment. For example, in Patent Document 1, the refrigerating compartment baffle is provided in the air passage under the refrigerating compartment duct. [Prior Patent Document] [Patent Literature]

[Patent Document 1] Japanese Patent Application Publication No. 2018-109501

[The problem to be solved by the invention]

The conventional technology described in Patent Document 1 has the following structure. The refrigerating compartment baffle is provided at a position higher than the joint surface of the refrigerating compartment duct and the partition plate constituting the floor surface of the refrigerating compartment, and further, A drainage member is provided at a position higher than the refrigerating compartment baffle. By adopting this structure, the condensed water can be guided so that the condensed water does not reach the vicinity of the baffle of the refrigerating compartment during the process of flowing from the top to the bottom by gravity, but flows to other harmless places, such as the cooler compartment.

If the refrigerating compartment baffle is installed below the floor of the refrigerating compartment, such as a corner of the cooler compartment cover, it is impossible to prevent the condensation water generated below the drainage member from joining the duct and the partition of the refrigerating compartment. The surface flows into the air duct and is attached to the baffle of the refrigerating compartment. Therefore, the installation position of the refrigerating compartment baffle is restricted to the refrigerating compartment duct on the upper side of the refrigerating compartment floor.

When considering the handling of the power supply wiring and control wiring of the baffle, the ease of assembly of the air duct element itself, the ease of repair, and the breadth of the food storage space in the refrigerator compartment, the refrigerator compartment baffle is designed to obtain design freedom The refrigerator with high and better usability is highly likely to be installed separately from the refrigerating compartment duct in the air duct below the refrigerating compartment duct. However, in the past, only the refrigerating compartment baffle was installed in the refrigerating compartment duct. In this case, there is a problem that, for example, the storage space for food in the refrigerating compartment must be reduced. Furthermore, in the conventional technology, since the drainage member is an independent member, it also has the problem of additional material cost and manufacturing cost in order to install the drainage member.

The present invention is to solve the above-mentioned problems, and its object is to provide a refrigerator that can suppress the material cost and manufacturing cost while suppressing the adhesion of dew condensation water to the baffle plate. [Means to solve the problem]

The refrigerator of the present invention includes: a heat-insulating box body in which a refrigerating room and a cooler room are arranged; a cooler is arranged in the cooler room and cools the air supplied to the refrigerating room; a duct for the refrigerating room, It forms a part of the air path that guides the cold air cooled by the cooler from the cooler compartment to the refrigerating compartment; the refrigerating compartment floor element is arranged on the lower side of the refrigerating compartment duct and constitutes the floor of the refrigerating compartment And the baffle is set in the air path, and adjusts the flow of cold air flowing in the air path; in the refrigerating room floor element, the refrigerating room duct is tied to the side of the refrigerating room duct to form a refrigerating room return air passage, And a groove extending from directly under the duct of the refrigerating compartment to the return air passage of the refrigerating compartment is formed, and the return air passage of the refrigerating compartment is the refrigerating compartment return through which the air after cooling the refrigerating compartment passes when returning to the cooler compartment The entrance of the wind road. [Effects of Invention]

According to the refrigerator of the present invention, the refrigerating compartment floor element constituting the floor surface of the refrigerating compartment is formed with a groove extending from directly under the duct of the refrigerating compartment to the return air passage of the refrigerating compartment. That is, the groove forms a drainage path from directly below the refrigerating compartment duct to the refrigerating compartment return air passage. As a result, the baffle is installed in the air path lower than the refrigerating compartment floor element, and the dew condensation water located on the junction surface of the refrigerating compartment duct and the refrigerating compartment floor element flows in the groove and goes outside the air path where the baffle is installed The return air path of the refrigerator compartment is drained. Therefore, dew condensation water can be prevented from flowing into the air passage from the joint surface of the refrigerating compartment duct and the refrigerating compartment floor element to adhere to the baffle. Furthermore, since the drainage groove is formed integrally with the refrigerating compartment floor element, material costs and manufacturing costs can be suppressed.
