ル材である。A cooler 8 is installed at the back of the freezer compartment.
At the upper part of the cooler 8, a cooling air circulation ring 9 is provided, and at the lower part of the cooler 8, there is provided a dew tray 1o for receiving defrosting water that has melted the frost attached to the cooler 8. This dew saucer 1
There is a cylindrical drainage hole 10a on the bottom of o for draining defrosting water.
has been established. Reference numeral 11 designates a drain pipe which is inserted and connected to the tip of this drain hole 10a and is buried in the urethane insulation material 4, and is extended by an evaporation plate 12'' provided at the bottom of the refrigerator main body 1.The partition wall 6 is made of polystyrene foam or the like, which has a duct 13 through which cold air circulated through the refrigerator compartment returns to the cooler 8, and a hole 14 that covers the outer periphery of the dew pan 1o and penetrates through the drain hole 10a3. A formed heat insulating material 15 is provided.The remaining 16 is a drainage hole 10a.
This is a fixture that fixes the drain pipe connected to the tip. 17
is a sealing material that prevents the urethane heat insulating material 4 from entering through the gap 18 formed between the hole 14 of the heat insulating material 15 and the drain hole 10a.

ン断熱材４が浸入し丸鋸受皿１ｏ内へ流れ込む。Problems to be Solved by the Invention However, in such a configuration, the dew pan 1 is not attached to the heat insulating material 15.
After installing o, insert the drain pipe 11 into the tip of the drain hole 10a, fix the connecting part with the fixture 16, and then seal the sealing material 1.
However, when installing the drain pipe 11 at the bottom of the refrigerator main body 1, a considerable tensile force or lateral force is applied to the connection part of the drain pipe 11, so the sealing material 17 is used to seal the gap 18. moves, the seal breaks, and the urethane heat insulating material 4 enters through the gap 18 and flows into the circular saw tray 1o.

。If a tensile force is still applied to the connecting part, the drain pipe 11 will be pulled out from the drain hole 10a, creating a gap, and the urethane insulation material 4 will penetrate into the drain pipe 11 through the gap, causing a blockage and impairing the drainage function. There are things that will not be fulfilled. In addition, the gap formed between the insulation material 15 and the outer periphery of the dew pan 10 and the insulation material 15
Since there is a gap 18 between the hole 14 and the outer periphery of the drain hole 10a, if a large amount of humid air flows into this gap,
Water drops adhere to the outer periphery of the dew pan 10 and flow downward, but since there is a sealing material 17 at the tip of the gap 18, the gap 18
As a result, water droplets become frozen during cooling operation. Pressure force is applied to the insulation material 15 due to volumetric expansion during freezing, and the ice destroys the surface of the insulation material 15 and penetrates into the inside of the insulation material 15, causing destruction of the insulation function of the insulation material 15 and damage during defrosting. Since a large amount of heat is taken away from the heater, the defrosting function deteriorates and cooling becomes impossible, which is a quality problem.

としている。The present invention solves these conventional problems by ensuring that the drain pipe is securely attached to the drainage hole of the drain pan, prevents the insulating material from entering the drain pan, and also prevents the insulating material from entering the drain pan. The purpose is to ensure that the water accumulated between the dew pans flows into the drain pipe.

A drain hole 19 is provided at one end of the drain pipe 20.
A locking piece 1 having a flat protrusion 19b provided in a
A locking portion 20a that locks on the drain hole 19c is provided, and a gap 21 is provided between the locking portion 20a and the outer periphery of the drain hole 19a. It also has a circular seal portion 20b formed at the upper tip of the locking portion 20a.

きる。In the above configuration, when attaching the drain pipe 20 to the drain hole 19a, it is easy to attach the drain pipe 20 to the drain hole 19a because the locking piece 19c having the protrusion 19b provided on the outer periphery of the drain hole 19a has a cut groove 19d as shown in FIG. and is inserted into the locking part 20a. After the locking piece 19c is inserted into the locking part 2 Oa, the locking piece 19c returns to its original position and is locked to the locking part 20a, so that the drain pipe 20 can easily fit into the drain hole 19a. The installation is connected, and even if an external force such as a tensile force is applied to the connection part,
Hole 2 of the heat insulating material 26 without any gaps, misalignment, or coming off.
The sealing material 26 between the lower part 27 of the 4 and the sealing part 20b can be reliably sealed without applying any external force, and the urethane heat insulating material 4 will not penetrate at all, and a sufficient drainage channel can be secured. In addition, the gap 22 on the bottom of the dew pan 19 and the drainage hole 1
The gap 23 between the outer circumferences 9a and the locking part 20 of the drain pipe 20
Since the gap 21 between the outer circumference of the drain hole 19a and the outer circumference of the drain hole 19a communicate with each other and form a drainage channel, the condensed water adhering to the outer circumference of the dew pan 19 flows into the drain pipe 2Q through the gap during defrosting, and the surface of the insulation material. Destruction and deterioration of defrosting function can be prevented.

ある。Effects of the Invention As is clear from the above description, the present invention includes a locking portion that locks to a flat protrusion provided near the tip of the drain hole of a dew pan provided at an opening at one end of a drain pipe; It consists of an oval-shaped sealing part formed at the upper end of the locking part and a sealing material provided between this sealing part and the lower part of the hole in the heat insulating material made of styrofoam, etc. By locking the locking part of the pipe to the locking piece having a flat protrusion on the drain pan, the drain pipe can be securely attached to the drainage hole of the drain pan, and external forces such as tensile force will not be applied to the connecting part. Even if the heat insulating material is added, there will be no gaps, deviations, or dislodgements, and the seal will be reliably sealed, and the urethane insulation material will not seep in, ensuring a sufficient drainage channel. In addition, a locking part is provided on the drain pipe with a gap between the outer peripheries of the drain hole, the outer periphery of the drain tray is covered, a gap is provided on the bottom surface, and the hole is made of a heat insulating material having a gap between the outer peripheries of the drain hole. Therefore, these gaps communicate with each other to form drainage channels, and the condensed water that adheres to the outer periphery of the dew pan flows into the drain pipe through the gaps during defrosting, causing damage to the surface of the insulation material and heat from the heater during defrosting. This has the effect of preventing deterioration of the defrosting function and failure of cooling due to the removal of a large amount of defrost.
