And a foam heat insulating material 4 and the like filled between the two. Behind the freezer compartment 5, an evaporator 6 is provided.
And a blower fan 7 for circulating the cool air generated in the above-mentioned manner in each room such as the freezing room 5. A dew tray 8 is provided at a lower portion of the evaporator 6, and a defrost heater 9 that is turned on during a defrosting operation is provided substantially at the center of the dew tray 8. The dew tray 8 is for receiving defrost water flowing down from the evaporator 6 side when the refrigerator is operated for defrosting operation. 1 is guided to a machine room 11 formed at the rear of the lower part, and enters an evaporating dish 13 attached to an upper part of a compressor 12 arranged in the machine room 11, where
It is made to evaporate using the heat of 12 mag.

FIG. 2 shows the machine room 11 obliquely from the rear. The machine room 11 is divided by a partition body 15 having ventilation holes 14, and a blower 16 is provided in one of the chambers facing the ventilation holes 14.
In the other chamber, a condenser 17 and a compressor 12 are provided.

FIG. 3 is a plan view showing the machine room 11 from the back. The upper wall of the machine room 11 is constituted by a bottom plate 2a of the outer box 2, and the partition 15 below the bottom plate 2a and the evaporator 15 are evaporated. Between the dishes 13, a pair of air guide plates 18 are formed to face each other and protrude downward,
It is configured to guide the air blow from the blower 16 to the upper part of the evaporating dish 13. Further, the air guide plate 18 is formed by cutting and raising the bottom plate 2a of the outer box 2 to be integrally formed.

FIG. 4A is a view from below showing a state before the wind guide plate 18 is cut and raised from the bottom plate 2a, and FIG.
5 is a sectional view taken along the line aa of FIG.
Shows a state in which is raised. As shown in FIG. 4 (A), the bottom plate 2a is cut out in a substantially U-shape, and a flange 18b is formed on the periphery of the cutout portion 18a. A plurality of slits 18c are provided in the section.

As shown in FIG. 4B, before the air guide plate 18 is cut and raised, a notch 18a and a plurality of slits 18c are formed.
Aluminum tape 19 that covers the bottom plate 2a from the top of the flange 18b
Then, the heat insulating material 4 is filled between the outer box 2 and the inner box 3. After the heat insulating material 4 is filled, the air guide plate 18 is vertically bent and cut up. At the time of bending, the slit 18c was provided and a flange was provided between the aluminum tape 19 and the bottom plate 2a.
Since the gap is formed from 18b, the air guide plate 18 can be easily bent.

As shown in FIG. 5, the distance between the pair of opposed air guide plates 18 is made wider on the side of the evaporating tray 13 than on the side of the partition 15, and the air collected on the side of the partition 15 is supplied to the evaporating tray 13. It is configured to blow over the entire top surface.

In the above configuration, the defrost water collected in the evaporating dish 13 is evaporated by the heat of the condenser 17 and the compressor 12 and the water absorbing plate, and the heat of the machine room 11 is opposed by the blower 16. By blowing the air collected from the ventilation path formed by the pair of air guide plates 18 into the evaporating tray 13 and the water absorbing plate, the evaporation of the defrost water can be accelerated and the amount of evaporation can be increased. Further, by integrating the air guide plate 18 with the bottom plate 2a, the number of components can be reduced, and the refrigerator can be downsized.

[0021]

According to the present invention as described above,
The air in the machine room is blown by a blower, and the air collected from a ventilation path formed by a pair of air guide plates facing each other is applied to the inside of the evaporating dish and the water absorbing plate, thereby accelerating the evaporation of the defrost water and reducing the amount of evaporation. In addition, the number of components can be reduced by integrating the air guide plate with the bottom plate, and the refrigerator can be downsized.
