Description

[Detailed Description of the Invention] The present invention relates to a refrigerator having at least two food storage compartments capable of storing refrigerated or frozen foods, and particularly promotes uniform circulation of cold air.

Next, an embodiment of the present invention will be explained based on the drawings.

1 is a refrigerator compartment outer box, 2 is a freezer compartment, 3 is a refrigerator compartment, and 4 is an inner box combined with the outer box 1, which includes a freezer compartment portion 4a and a refrigerator compartment portion 4.
b and the partition wall portion 5 that partitions the two chambers 2 and 3 are made of synthetic resin that is integrally formed by vacuum forming or the like, and is generally relatively easily deformed during assembly with the outer box 1 even after molding. It is in a bendable state.

The partition wall portion 5 of the inner box 4 has a front end positioned rearward from the periphery of the opening of the inner box 4 to form a terminal end, a protrusion 6 that rises slightly upward, and further lowers toward the upper drainage lower. The lower surface forms the ceiling surface of the refrigerator compartment 3, and the thickness between the upper surface and the lower surface is relatively thicker in the rear part than in the front part than in the drainage lower part, and the partition wall part 5 is formed in the rear part. It has a shape that opens to the left and right sides.

8 is a foam insulation material, including the partition wall portion 5, the outer box 1 and the inner box 4.
The foam is filled into the space formed by using an in-situ foaming method with the opening 17 (described later) as the bottom, and is made of, for example, polyurethane foam resin.

A cold air duct member 9 is attached to the back wall of the inner box 4 and forms a cold air passage 10 between the freezer compartment 4a, the partition wall 5, and the refrigerator compartment 4b.

Reference numeral 11 denotes a closing plate that closes off communication between the partition wall portion 5 and the cold air passage 10, and is combined with the cold air duct member 9 to close a portion of the rear opening of the partition wall portion 5.

12 is a cold air discharge port communicating with the cold air passage 10 to the freezer compartment 2, and 13 is a cold air discharge port communicating with the cold air passage 10 to the refrigerator compartment 3.

Reference numeral 14 denotes an electric blower for circulating cold air, which is attached to a recess 15 formed in the middle of the cold air duct member 9.

Reference numeral 16 denotes a partition front wall, and a front opening 17 of a heat insulating box body composed of an inner box 4, an outer box 1, and a heat insulating material 8 is brought into contact with the front end of the partition wall portion 5 horizontally in the left and right direction, and the front opening 16 is a partition front wall. It is attached to the left and right side walls after the insulation box is constructed so as to divide the section 17 into a freezer compartment opening 2A and a refrigerator compartment opening 3A.

Reference numeral 18 denotes a cold air suction passage formed between the partition wall portion 5 and the freezer compartment 2, and is formed by the partition wall portion 5 and a partition wall 19 detachably attached to the inner box 4 above the partition wall portion 5. , the partition wall 19 has a heat insulating material 20 that abuts the upper surface of a plate-fin-tube type cooler 21 placed on the partition wall portion 5 so as to be accommodated in the cold air suction passage 18 .

Therefore, the partition wall 19 constitutes the bottom wall of the freezing chamber 2.

Reference numeral 22 denotes a cold air suction port of the freezer compartment 2 formed in the front part of the partition wall 19, which communicates with the cold air suction passage 18.

Reference numeral 23 denotes a cold air suction port of the refrigerator compartment 3 formed inside the partition front wall 16, which communicates with the cold air suction passage 18 at a position higher than the projection 6 to prevent backflow of cold air when the electric blower 14 is stopped. There is.

24 is a damper set thermostat that controls the temperature of the refrigerator compartment 3 to a predetermined temperature by sensing the temperature of the refrigerator compartment 3 and opening and closing a cold air outlet.

Reference numeral 25 denotes an electric compressor that constitutes a refrigerant circulation cycle, that is, a refrigeration cycle, together with the cooler 21, and a temperature control device that senses the temperature of the cooler 21 and the cold air discharged to the freezer compartment 2 or the freezer compartment 2, and controls the operation. The operation is stopped and the temperature of the freezer compartment 2 is maintained at a predetermined temperature.

The air cooled by the cooler 21 passes through the partition wall portion 5 of the inner box 4.
The cold air passes through the cold air passage 10 from the cold air hole 26 formed slightly above the hole 26 by the electric blower 14 facing the hole 26, and is distributed to the freezer compartment 2 and the refrigerator compartment 3 for circulation.

The openings 2A and 3A of the freezer compartment 2 and the refrigerator compartment 3 are respectively closed by separate heat insulating doors 30 and 31, and these doors are pivotally supported by the heat insulating box body so as to be openable and closable.

A drain outlet pipe 27 connected to the drain lower is passed through the heat insulating material B in the partition wall portion 5 and extends rearward slightly lower, connected to an external drain pipe 28, and installed in the lower machine room of the heat insulating box. Defrosting water from the cooler 21 is introduced into the evaporating dish 29.

The cold air duct member 9 including the drain pipe 27 and the closing plate 11 is installed in the inner box 4 in advance and filled with the heat insulating material 8, and is sufficiently held and insulated by the heat insulating material 8.

The present invention is a refrigerator that has a partition wall portion as described above, and an inner box that integrates each portion of the freezer compartment and the refrigerator compartment.

Since the partition wall portion is integrated with the inner box formed by vacuum forming or the like, the length of the forward protrusion may differ from case to case, or unevenness may occur at the front end of the partition wall portion. If the front end is one wall of the cold air suction port, the position of the cold air suction port will not be constant depending on the individual product, and will vary back and forth, and its size will differ, making it difficult to make it uniform.

If the position and size of the cold air intake ports cannot be made uniform, the cold air circulation path and amount of cold air into the refrigerator compartment will be different, and the cooling temperature distribution will not be determined. Therefore, the operating conditions of the damper set thermostat etc. must be set for each product. Adjustments must be made, which is a major drawback in mass production.

However, in this case, the front end of the partition wall is located behind the inner box opening periphery, and the front end of the partition is provided with the cold air inlet of the refrigerator compartment formed inside, so the position and size of the cold air inlet are etc. are approximately constant, the amount of cold air circulated, etc. is made uniform, making it suitable for mass production and improving cooling efficiency.
