BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator provided with an evaporating dish at a lower portion of a refrigerator main body for receiving and storing defrost water generated due to defrost of a cooler.

[0002]

In a refrigerator, a cooler for cooling the inside of the refrigerator is generally provided at the back of the refrigerator body, and when the amount of frost attached to the cooler increases,
Because the cooling function is reduced, to remove frost,
The defrosting operation is performed periodically, for example, every time the accumulated operation time of the compressor that supplies the refrigerant to the cooler reaches a predetermined time. In this defrosting operation, power is supplied to a defrost heater provided near the cooler, and the frost is melted by the heat of the heater.

[0003] Defrost water generated due to the defrost of the cooler is stored in an evaporating dish disposed in a machine room below the refrigerator main body, and is evaporated by the next defrost operation.
The evaporating dish is designed to have about 1.5 times the capacity of the defrost water generated by one ordinary defrost, and receives the heat of the compressor to promote the evaporation of the stored defrost water. It is located at the top of the compressor for easy access,
In a normal use state, the defrost water does not overflow from the evaporating dish.

In such a case, the amount of defrost water generated along with the defrost also increases, so that the defrost water may overflow from the evaporating dish.

[0005] However, even if the water overflows from the evaporating dish and wets the floor surface, if the water is a part hidden by the refrigerator body, the user does not notice or the notice becomes slow. And the response may be delayed.

In order to cope with such a problem, conventionally, a gutter-shaped water guide member is provided between an evaporating dish and a dish-shaped duct provided on the lower surface of the refrigerator main body, and the evaporating dish is provided. When the defrost water overflows from the water, the water is received by the water guide member and guided to the duct, and the water is guided to the front side of the refrigerator body through a hole formed in the front of the duct.

However, in the above-mentioned conventional structure, the water guide member is formed as a member separate from the evaporating dish and the duct, so that the number of parts is large and the cost is high. When assembling the main body into the machine room, there is a disadvantage that the work is troublesome. Further, when the amount of defrost water stored in the evaporating dish increases, the evaporating dish needs to be supported via the water guide member, but the supporting of the evaporating dish is unstable.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a case where when defrost water overflows from an evaporating dish, the water is guided to the front side of the refrigerator body. An object of the present invention is to provide a refrigerator capable of reducing the number of parts, reducing costs, improving workability of assembling work, and favorably supporting an evaporating dish.

In order to achieve the above-mentioned object, the present invention comprises an evaporating dish at a lower portion of a refrigerator main body for receiving and storing defrost water generated due to defrost of a cooler. In the refrigerator, the evaporating dish is provided integrally with a water guide for guiding water overflowing from the evaporating dish to the front side of the refrigerator main body, and the lower end of the water guide is supported. It is assumed that.

In the above configuration, when defrosted water overflows from the evaporating dish, the water is guided to the front side of the refrigerator body via the water guide, so that the user can see the water. As a result, they quickly become aware of the overflow.

Since the water guide is provided integrally with the evaporating dish, the number of parts can be reduced as compared with the case where the water guiding member is used as a separate member from the evaporating dish and the like. Further, since the lower end of the water guide is configured to be supported, the evaporating dish can be favorably supported via the water guide.

In this case, it is preferable that the water guide is connected to the evaporating dish via a self-hinge part.
