Abstract

PROBLEM TO BE SOLVED: To prevent not only a shorter cycle of cool air and poor cooling as caused by foods and vinyl bags which drop from the rear of a case to clog a suction port. SOLUTION: In this refrigerator with a pullout type refrigerating chamber, cool air 50 cooled by a cooler 6 is blown out at blowoff ports 12a and 12b of a cool air guide plate 20 protruding to the front of cases 30a and 30b (30) and sucked into a suction port 13 of the cool air guide plate 20 arranged on an inner floor surface of the refrigerating chamber after passing through the front from the rear of the case 30. A rib and a hole are arranged at upper parts of a rear wall and a side wall of the case 30. This prevents the blowing of the cool air directly to the suction port from the blowoff ports and the clogging of the suction port by dropping foods.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a longitudinal sectional view of a main part of the refrigerator, and FIG. 2 is a front view of the main part of the refrigerator with a door removed. Next, the operation will be described. In FIG. 1, the cool air 50 sucked from the cool air suction port 13 provided in the cool air guide plate 20 passes through the cooler 6 located between the bell mouth 21 and the inner box 5 and is rotated by the blower motor 10. The air is blown by the fan 11 to the outlets 12 a and 12 b provided on the cold air guide plate 20. The cool air 50 blown out from the outlet 12 is the case 30 3
Air is blown from the rear surfaces of the doors 0a and 30b to the front surface on the door side, and is sucked into the cool air suction port 13 located at the back of the freezing room floor. The cool air 50 is supplied from the outlet 12a to the storage case 30a.
(Refrigerator door) side, it is possible to prevent a short cycle of cold air (cool air is returned to the suction port without being blown to the front side of the door). The outlet 12b may also be formed in a shape protruding toward the front surface on the door side. The storage case is a container provided at an upper portion thereof, which is provided easily for pulling out, and stores foods and the like inside.

FIG. 3 is a partially enlarged view of FIG. 1, and FIG. 4 is a perspective view of a main part of FIG. 3, in which a rib 31 is provided on the upper rear surface of the storage case 30a. This prevents falling from the back of the case 30a and blocking of falling objects from blocking the suction port 13. Although the cross section of the rib is triangular in FIG. 4, the cross section may be square or round, or a single plate.
Further, the rib refers to a rib standing on an upper end surface of a storage case or the like.

In FIG. 3, the height dimension A of the rib 31 is larger than the dimension B formed by the outlet 12a and the storage case 30a.
(B-15) ≦ A ≦ (B-5) mm is a standard. In addition, the height dimension of the storage case is determined by the ease of withdrawing the storage case, the ease of taking out the stored food, and the like.
The height of the rib is determined by the type of the stored food, the position of the cool air outlet, and the like.

The rib 31 is formed integrally with the storage case 30a.

In FIGS. 3 and 4, reference numeral 60 denotes a load line, which serves as a measure of the height at which food can be stored. This reduces the need for the user to store food that is higher than the load line 60, thereby preventing the food from being caught. Embodiment 2 FIG.

The ribs 31 are provided not only at the upper portion of the rear surface of the storage case 30a but also at the upper portion of the side surface thereof to prevent the food from falling when the door (refrigerator door) is opened and closed, and to prevent the cooling failure caused by closing the suction port. The effect is obtained. Embodiment 3 FIG.

The rib 31 may have a shape as shown in FIG. This prevents foods and plastic bags from falling from the back of the storage case 30a, and prevents falling objects from blocking the suction port 13. Also, this shape improves the flow of cold air. Embodiment 4 FIG.

FIG. 6 is a perspective view of the main part of FIG. 3. Reference numeral 32 denotes a cutout formed in the rear wall of the case 30b, which has substantially the same area as the outlet 12b located behind the rear wall of the case 30b. The operation will be described. Cold air 50 is the outlet 1
The air is blown out of the case 2b and is drawn from the back of the case 30b to the suction opening 13 of the cold air guide plate 20 located at the back of the freezer compartment floor. The notch 32 allows the cool air to be sufficiently blown out.

FIG. 7 shows a storage case 30b according to the fourth embodiment, and a notch 32 provided in the storage case 30b.
Is provided with a rib 33. Thereby, the storage case 3
0b is prevented from dropping from the notch 32 and falling objects from blocking the outlet 12a. Also, since there is a gap through which the cool air passes as shown in FIG. Is done.

Embodiment 5 FIG. 8 shows a storage case 30b according to the fifth embodiment, in which a hole 34 is provided in a range that blocks the cool air from the outlet 12b in the cool air guide plate 20, and the cool air 50 is provided on the door 2 side of the storage case 30b. Flowed forward.

The suction port 13 is provided at the back of the freezer compartment floor. However, even if the suction port 13 is provided at the front of the freezer compartment floor as shown in FIG.
a is not blocked, and the same effect can be obtained.

In the above-described drawings, the refrigerator door is a drawer type refrigerator, but the refrigerator door may not be a drawer type such as a double door.

In the above description, the freezing room has been described, but the same applies to a refrigerator room or the like other than a freezing room.

In the above description, the storage case 30a is provided with a rib at the upper rear and the storage case 30b is provided with a cutout or a hole at the upper rear. However, the position of the storage case and the cool air outlet is not limited. Depending on the relationship, it is desirable to provide ribs, notches, and holes in the storage case so that the cool air can be easily blown out.

Since the present invention is configured as described above, it has the following effects.

A cooler, a blower fan for blowing out the cool air cooled by the cooler, an outlet for introducing the cool air into the refrigerator, a suction port for returning the blown cool air to the cooler, and a drawer are provided. And a storage case for storing food, wherein the ribs are provided on the upper part of the rear wall of the storage case, so that the load line of the storage case becomes clear, and the cold air suction port is formed by the fall of the stored items and the falling objects. It is possible to prevent blockage and cooling failure.

Since the ribs are also provided on the upper side wall of the storage case, it is possible to further prevent the storage items from falling.

A cooler, a blower fan for blowing out the cool air cooled by the cooler, an outlet for guiding the cool air into the refrigerator, an inlet for returning the blown cool air to the cooler, and a drawer are provided so as to be able to be drawn out. A storage case for storing food, wherein a cutout portion having a size substantially equal to the area of the outlet is provided in a portion of the back wall of the storage case facing the outlet, so that the outlet is provided. The cool air blown out of the case can flow to the front of the case.

Since the ribs are provided in the cutouts of the storage case, it is possible to prevent the storage items in the storage case from falling and the cold air suction port from being blocked by the falling objects.

A cooler, a blower fan for blowing out the cool air cooled by the cooler, an outlet for guiding the cool air into the refrigerator, an inlet for returning the blown cool air to the cooler, and a drawer are provided. And a storage case for storing food, in the refrigerator provided with a hole in a portion of the back wall of the storage case facing the outlet,
The cool air blown out from the outlet can be flowed forward of the case.
