  FIG. 7 is a cross-sectional view of a refrigerator main body 1 as a conventional example. The storage room consists of a refrigerator room 2, a vegetable room 3, and a freezer room 4 from the top. The refrigerator room 2 has a refrigerating rotary door 6 held by a hinge mechanism 5, and the vegetable room 3 has a vegetable drawer door 7, a freezer. The chamber 4 is configured as a storage configuration having an upper freezer drawer door 9 and a lower freezer drawer door 10. The method of configuring the storage form of the freezer compartment 4 includes a method of forming two sheets of an upper stage freezer drawer door 9 and a lower stage freezer drawer door 10 as shown in FIG. 7, and a freezer drawer door 8 as shown in FIG. A method consisting of sheets is employed.

  In the refrigerator compartment 2, a plurality of pockets 11 on the side of the refrigerating revolving door 6 and a plurality of shelves 12 on the side of the refrigerator main body 1 are arranged. Refrigerated foods such as beverages, seasonings and prepared dishes and refrigerated foods stored in the refrigerator compartment 2 are classified and stored in each storage unit in terms of size, quantity, shape, and convenience. The vegetable room 3 is composed of a lower vegetable container 13 drawn out by the vegetable drawer door 7 and an upper vegetable container 14 installed on the upper part thereof, each from the viewpoint of the size, quantity, shape, and convenience of the stored vegetables and fruits. Are classified and stored in storage containers.

  The inside of the freezer compartment 4 shown in FIG. 7 is composed of an upper freezer container 16 drawn out by an upper freezer drawer door 9 and a lower freezer container 15 drawn out by a lower freezer drawer door 10 installed in the lower part thereof, and stored frozen food. And the size and amount of frozen foods, shape, and usability are classified and stored in each storage container. Further, the inside of the freezer compartment 4 shown in FIG. 8 is composed of a lower freezing container 15 drawn out by the freezing drawer door 8 and an upper freezing container 16 formed on the upper part thereof, and the size and amount of frozen food and frozen food to be stored therein. It is classified and stored in each storage container in terms of shape, usability, etc.

  In the configuration of each storage chamber, the machine room 18 in which the compressor 17 and the like are installed is installed at the lower back of the freezer room 4 as shown in FIG. 7 or FIG. It is the structure arrange | positioned in the upper part of the machine room 18 through a part of heat insulating material which forms the refrigerator main body 1 in the back surface of the vegetable compartment 3, or as shown to FIG. 9 and FIG. A method is adopted in which a part of the heat insulating material forming the refrigerator main body 1 is formed between the back surface and the machine room 18.

  The refrigeration cycle for cooling the inside of the refrigerator will be described with reference to a sectional view of the refrigerator main body 1 in which the compressor 17 and the cooler 20 shown in FIGS. The compressor 17 and the cooler 20 installed on the back of the freezer compartment 4 are rotated by a fan driving motor 21 provided on the upper side of the cooler 20 to rotate the forced ventilation fan 22. Is circulated and heat exchange in the cooler 20 is promoted, and the cooled cold air is circulated in the refrigerator main body 1 through the cold air passage 23.

  A defrosting tube heater 25 is disposed below the cooler 20, and a defrosting water bottle 26 is disposed below the tube heater 25. The temperature of each storage room provided in the refrigerator main body 1 is controlled so that the temperature of each storage room is maintained at a predetermined temperature by opening / closing operation of a cold air amount adjusting damper 24 installed in a part of the cold air passage 23. Has been made.

  When the storage chamber configuration of the conventional refrigerator shown in FIG. 7 or FIG. 8 and the positional relationship between the machine room 18 and the cooler 20 forming the refrigeration cycle are observed, the machine room 18 is installed at the lower back of the freezer room 4. However, the cooler 20 is installed across the back of the freezer compartment 4 and the vegetable compartment 3 so that the depth of both storage compartments is shallow and the storage container is complicated, and the storage capacity of both storage compartments is reduced. If it tries to increase, while the partition wall position between the refrigerator compartment 2 and the vegetable compartment 3 arrange | positioned in the upper part will necessarily become high, the position of the vegetable drawer door 7 of the vegetable compartment 3 will be raised. This situation is the same when the cooler 20 shown in FIGS. 9 and 10 is installed between the machine room 18 and the freezer room 4.

  Furthermore, the freezer compartment 4 having the lowest temperature in the storage room is provided adjacent to the machine room 18 where the temperature is increased, so that the thickness of the heat insulating material necessary for thermally shutting off the two can be reduced. In order to ensure the total capacity of the upper freezer container 16 and the lower freezer container 15 as the required capacity due to the fact that it must be ensured and the depth of the freezer compartment 4 is shallow, the total depth dimension of both freezer containers is set to It is necessary to increase the depth of both the upper and lower freezing containers 16 and 15, and it becomes difficult to put in and out the stored items. A part of the heat insulating material forming the main body provided in the container protrudes to the inside of the warehouse.

  Furthermore, the depths of both the freezing containers constituted by the upper and lower freezing containers 16 and 15 cannot be efficiently divided, and there are restrictions in terms of storage and usability. In the freezer room 4, there is a tendency for frozen foods to increase at home, and now it is desired to increase the capacity of the freezer room 4. .

  In the vegetable room 3, the cooler 20 is installed at the rear rear part in the same manner as the freezer room 4, and the depth becomes shallower, and it is necessary to increase the depth dimension in order to secure the necessary capacity. The total container depth of the upper vegetable container 14 and the lower vegetable container 13 is increased, the container form is difficult to put in and out of storage, hindering the usability, and the storage part height of the freezer compartment 4 provided in the lower part is In addition to the rise, the position of the partition wall that separates the refrigerator compartment 2 and the vegetable compartment 3 is further increased, and at the same time the position of the vegetable drawer door 7 in the vegetable compartment 3 is increased. The upper limit of the height of the vegetable drawer door 7 calculated based on the female average height of about 156 centimeters exceeds 93 centimeters, and the height is difficult to put in and out, impeding usability.

  Furthermore, in the vegetable room 3, there is a tendency to increase the number of fruits and vegetables at home in conjunction with health and nutrition orientation, and there is a trend to expand from the market trend now that a large capacity of the vegetable room 3 is desired. The response is becoming more difficult. Moreover, in the refrigerator compartment 2, as shown in FIG.7, FIG.8, FIG.9 and FIG. 10, the amount of cold which controls the amount of cold discharged by the forced ventilation fan 22 from the cooler 20 provided in the lower back part. An adjustment damper 24 is installed in a part of the cold air passage 23, and is formed to straddle the lower back of the refrigerator compartment 2 and the upper back of the vegetable compartment 3. Accordingly, in the refrigerating chamber 2, a convex portion is formed at the back of the lowermost storage section of the shelf 12 on the main body side, and the depth below the lowermost shelf 12 is shallow, thereby impeding storage.

  In addition, as the height dimensions of the lower freezer drawer door 10, the upper freezer drawer door 9, and the vegetable drawer door 7 of the vegetable room 3 are increased, the height dimension of the refrigerating revolving door 6 itself of the refrigerating room 2 is increased. Will be reduced, and the amount of food to be stored in the pocket 11 on the refrigerator door 6 side will have to be reduced. In addition to the diversification of beverage container sizes and types such as bottles, cans, paper packs, and PET bottles, the seasoning is also diversified in container sizes and types. It is supposed to go against the increase. In the storage part of the shelf 12 on the main body side of the refrigerator compartment 2, it is difficult to reach the food stored in the back of the uppermost shelf 12, and further improvement in usability is required.

  To summarize the problem, the necessary capacity of the freezer room 4 and the required capacity of the vegetable room 3 are secured, the storage capacity of the pocket 11 on the side of the refrigerating revolving door 6 of the refrigerated room 2 is secured, and the vegetable drawer of the vegetable room 3 is further drawn. It is to suppress the height of the door 7 to 93 centimeters or less, which is the upper limit value of the height from the floor surface that does not hinder the use.

  7, FIG. 8, FIG. 9, and FIG. 10, the configuration of each storage room of the conventional refrigerator, the arrangement of the machine room 18 and the cooler 20 forming the refrigeration cycle, the required capacity of each storage room and the partition wall It is to review the relationship with the division position by, and to build a storage form that is highly efficient and easy to use.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a refrigerator with improved storage efficiency and usability.

In order to achieve the above object, a refrigerating chamber arranged at the top and opened and closed by a revolving door, a freezing room installed at the rear rear by a cooler and opened and closed by a drawer door, and a refrigerating cycle together with the cooler In a refrigerator provided with a compressor, in the present invention,
The compressor was installed above the rear part of the refrigerator main body, and the refrigerator compartment was positioned between the freezer compartment and the compressor.

  Moreover, in said refrigerator, the height dimension of the said refrigerator main body shall be a dimension larger than 156 centimeters, and the machine room which has the said compressor was provided in the back | inner side of the uppermost shelf provided in the said refrigerator compartment. .

  ADVANTAGE OF THE INVENTION According to this invention, the refrigerator which aimed at the improvement of storage efficiency and usability can be provided.

  A cooling unit having a height approximately equal to the height of the opening of the freezer compartment that forms the storage section as the lowermost storage room is installed at the rear rear part of the freezer compartment, and a compressor that forms the machine room, etc. Install it on the ceiling of an unusable refrigerator compartment or on the upper back of the refrigerator. Also, the forced draft fan used in combination with the cooler, fan drive motor, defrosting tube heater, and defrosting water trap are arranged so that most of them are located on the projection surface in the vertical direction of the cooler. Then, it is configured as a cooling unit.

  Therefore, the volume of the machine room has moved from the lower side to the upper side of the partition wall that partitions the refrigerator compartment and the vegetable compartment. If the volume of each storage compartment is constant, the compartment walls of the refrigerator compartment and the vegetable compartment are inevitably required. The position can be reduced by a height corresponding to the quotient obtained by dividing the volume of the machine room by the bottom area of the refrigerator body.

  Moreover, in the freezer compartment, it is possible to form the position of the heat insulating material at the rear rear part on the same plane as the heat insulating material that forms the back surface of the refrigerator body, and approximately the same as the height of the opening of the freezer room. Due to the synergistic effect of configuring the cooling unit at the rear rear part of the freezer compartment, the inner box shape in the freezer compartment becomes a simple rectangle, and the container depths of the upper and lower freezer containers formed inside are also stored. It is possible to set according to demands such as the size, amount, shape, and usability of food and ingredients.

  Furthermore, with the relocation of the machine room, the influence of the compressor that was the source of heat disappears, and it can be dealt with by ensuring heat insulation against room temperature. By moving to the rear rear part of the freezing room, the installation position of the damper for adjusting the amount of cold air that was installed in the part that forms the cold air duct directly above the cooling unit is changed from the position that spans the rear rear part of the refrigerator room and vegetable room By downsizing to a structure that can be lowered to the rear rear of the vegetable room and can be formed in the space in the cold air duct, it is not necessary to form a convex part on the rear rear of the bottom stage of the refrigerator compartment, ensuring a cold air duct Only the space is configured, and the inner box bottom surface integral obtained by subtracting the cross-sectional integral of the cold air passage from the cross-sectional integral including the heat insulating material required for the configuration of the cooling unit is expanded.

  Therefore, the quotient obtained by dividing the predetermined volume forming the vegetable room by the bottom area including the expanded portion is the height of the inner box of the vegetable room, increasing the capacity of the upper and lower vegetable containers of the vegetable room and the storage bottom area The height of the upper surface of the vegetable drawer door in the vegetable room is 93 cm or less, which is the upper limit of the height of the vegetable drawer door calculated based on the average height of Japanese adult women about 156 cm It becomes possible to set to a suppressed setting.

  In the refrigerator compartment, a compressor or the like forming the machine room is used, and the refrigerator is installed on the ceiling surface that is not convenient or on the upper back of the refrigerator main body. Therefore, with the movement of the machine room, the height of the freezer room and the vegetable room is reduced by the height that is the quotient obtained by dividing the volume of the machine room by the cross-sectional area of the refrigerator body. Inevitably, the height of the bottom surface forming the inner box of the refrigerator compartment is lowered, and the storage part of the refrigerator compartment can be configured as a height that is easier to use as a whole.

  In addition, the area behind the uppermost shelf in the refrigerator compartment where stored food is difficult to put in and out can be effectively utilized as a machine room. Furthermore, since the convex part formed as the installation part of the damper for adjusting the amount of cool air is also removed at the bottom of the shelf on the main body side of the refrigerator compartment, it is assumed that it has a highly storable form that can be used effectively to the back of the shelf. Can be possible.

  The storage area of multiple pockets provided on the refrigerated revolving door side of the refrigeration room can also be expanded downward by the amount of the partition that makes up the partition wall of the refrigeration room and vegetable room, so that beverages and seasonings This will also ease the storage of bottles that could not cope with the increase.

  Hereinafter, as an embodiment using the above-described means according to the present invention, FIG. 1 is a cross-sectional view of an embodiment in which the door of the freezer compartment 4 is composed of two pieces of an upper freezer drawer door 9 and a lower freezer drawer door 10, FIG.

The refrigeration room 2 has a refrigerating rotary door 6 held by a hinge mechanism 5, and the vegetable room 3 has It is configured as a vegetable drawer door 7, and includes a method comprising two sheets of an upper stage frozen drawer door 9 and a lower stage frozen drawer door 10 as shown in FIG. 1, and one sheet of a frozen drawer door 8 as shown in FIG. 2. The method of configuring is adopted. In the refrigerator compartment 2, a plurality of pockets 11 on the side of the refrigerating revolving door 6 and a plurality of shelves 12 on the side of the refrigerator main body 1 are arranged.

  Refrigerated foods such as beverages, seasonings and prepared dishes and refrigerated foods stored in the refrigerator compartment 2 are classified and stored in each storage unit in terms of size, quantity, shape, and convenience. The vegetable room 3 is composed of a lower vegetable container 13 drawn out by the vegetable drawer door 7 and an upper vegetable container 14 installed on the upper part thereof, each from the viewpoint of the size, quantity, shape, and convenience of the stored vegetables and fruits. Are classified and stored in storage containers.

  The inside of the freezer compartment 4 shown in FIG. 1 is composed of an upper freezer container 16 drawn out by an upper freezer drawer door 9 and a lower freezer container 15 drawn out by a lower freezer drawer door 9 installed in the lower part thereof, and stored frozen food. And the size and amount of frozen foods, shape, and usability are classified and stored in each storage container.

  Also, the inside of the freezer compartment 4 shown in FIG. 2 is composed of a lower freezing container 15 drawn out by a freezing drawer door 8 and an upper freezing container 15 formed on the upper part thereof, and the size and amount of frozen food and frozen food to be stored. It is classified and stored in each storage container in terms of shape, usability, etc.

  The aim of the present invention is to secure the necessary capacity of the freezer compartment 4 and the vegetable compartment 3, secure the necessary storage capacity of the pocket 11 on the refrigerating revolving door 6 side of the refrigerating room 2, The position of the partition wall between the vegetable compartment 3 is lowered, and the height of the vegetable drawer door 7 is suppressed to 93 cm or less which is the upper limit value from the floor surface that does not hinder the convenience. 9 and FIG. 10, the configuration of each storage room of the conventional refrigerator, the arrangement of the machine room 18 and the cooling unit 19 forming the refrigeration cycle, the required capacity of each storage room and the division position by the partition wall It is a construction of a storage form that has been reviewed from the relationship, has high storage efficiency, and is easy to use.
