[0009]

By the way, in the conventional refrigerator-freezer, it cannot be said that the limited indoor space of the freezer compartment, the refrigerator compartment, and the vegetable compartment is effectively used as described below. .. In the past, freezer-refrigerator was considered to be merely one of the kitchen supplies, but in recent years kitchens should be reconsidered as a comfortable living space. Should be seen as a kind of. However, the conventional refrigerator-freezer
They are not considered to be equivalent to other furniture, for example, they do not feel refreshed when they look inside.

(1) In a freezing room or a refrigerating room, an outlet for cool air is provided at the center of the back surface. For this reason, if an object is placed on the back surface, cold air will not be sufficiently blown out. Therefore, you can't put things too far away,
This substantially reduces the storage capacity. Especially in the cold room,
In order not to reduce the effective internal volume, the cold air duct is provided so as to project to the inside of the room, but at that part, the depth of the shelf plate becomes smaller and the storability deteriorates (in the case of a refrigerator with a narrow body width, Is especially difficult to use, and because the cool air outlet is provided in such a visible position,
The internal structure looks complicated and the refreshing feeling is lost. Furthermore, the cold air return port to the cooler of the refrigerator compartment is located in the center front of the lower part of the partition wall, and the cool air discharge port is also located almost in the center, so the temperature on both sides of the shelf plate tends to be higher than the center part. There is.

(2) The shelf boards used in the freezer compartment and the refrigerating room are made of plastic, and in order to increase the mechanical strength, ribs, steps, and U-shaped reinforcement are provided on the entire sides and each part of the shelf board. It is provided. If ribs are provided on the entire sides of the shelf board in this way, the area for placing things on the shelf board will be reduced by this amount, and the vertical height of the shelf board will become thicker, resulting in a smaller space for storing food, Hard to do. Further, if the structure and shape of the shelf plate are complicated, it is difficult to remove dirt and cleaning is difficult.

(3) In the freezing room and the refrigerating room, the shelves are provided as described above in order to effectively use the indoor space. To support the shelves, both inner side surfaces are supported. Is provided with an elongated protruding shelf rib extending from the door side to the back side. If there is such a projecting shelf rib, the support may interfere with some things to be put in, and the entire side surface of the room cannot be used, resulting in a waste of space. Therefore, if the mounting position of the shelf plate can be freely changed according to the height dimension of the stored item, the storability of the item will be further improved, but for that purpose, an additional shelf rib is required and the effective internal volume is The number of shelves is reduced, and the protruding shelf ribs are conspicuous, so that the interior looks cramped and a refreshing feeling is not obtained, and the cleanability is also deteriorated. Also, the height (size) of the shelf ribs
Due to the limitation of the width of the shelves, the height pitch of the shelf boards of the present refrigerators is almost 100-.
It has a constant pitch of 150 mm. Therefore, when you put tall food, you have to put it down (however, you can not open it) or remove the shelf (in that case, the shelf ribs will be visible and unsightly), On the contrary, when only a lot of short foods are put in, there is a problem that the inside of the refrigerator cannot be effectively used, because an unnecessary space is formed in the upper portion.

(4) In a freezing room or a refrigerating room, a lighting means is provided on the back surface of the room. Therefore, a part of the internal space is occupied by the lighting means, and the effective volume is reduced accordingly. Further, when the lighting means is provided at such a visible position, the structure of the interior of the room looks complicated and the refreshing feeling is lost. Moreover, since the interior of the room is illuminated from the back side, an object placed in the room is illuminated from the rear side and the front side becomes a shadow, giving a dark feeling.

(5) An automatic ice making device is provided in the freezing compartment, but the space of the automatic ice making device in the freezing compartment is quite large, and therefore the food storage capacity is significantly limited. become.

(6) In the vegetable compartment, in order to allow the drawer case to be put in and taken out, a rail is attached to a side surface of the compartment and a roller engaging with the rail is attached to an outer side surface of the drawer case. Therefore, the volume of the drawer case has to be made considerably smaller than the volume of the vegetable compartment.

Further, if the structure and shape of each room are complicated as described above, dirt easily collects and cleaning is difficult.

An object of the present invention is to solve the above problems, and to provide a freezer-refrigerator which can effectively utilize every corner of each room and makes the room feel refreshed.

[0018]

In order to achieve the above object, the present invention provides a plurality of pin holes facing each other on both side surfaces thereof in a freezer compartment or a refrigerator compartment, and the pin holes have flat plates. The pins for supporting the shelf-shaped shelf can be attached and removed.

Further, according to the present invention, the cold air outlets in the room are positioned on both sides of the back surface.

Further, according to the present invention, the cold air duct cover and the like on the rear surface of the room are made substantially flat, and the shelf plate is made of a substantially rectangular glass plate.

Further, in the present invention, the pin is made of metal, and the shape of the portion on which the shelf plate is placed is square.

Further, according to the present invention, a recess is formed on the side of the upper door of the room, the illumination means is provided in the recess, and the shelf is a transparent glass plate.

Further, the present invention provides an automatic ice making device in the door of the freezer.

Further, according to the present invention, rails are embedded in both sides of the vegetable compartment, and protrusions are provided on both sides of the outside of the drawer case to fit the rails.

[0025]

[Function] Since the pins only project from the side surface of the freezer compartment or the refrigerator compartment, the projecting portion becomes smaller than the conventional shelf ribs,
The inside of the room feels refreshed, and the side plates can be used more effectively due to the flat shape of the shelves. Further, not only the shelf plate but also the pin can be removed, so that the side surface becomes flat, which facilitates cleaning.

Since the cool air outlet is located near the corner of the back surface, it is possible to place an object up to the back surface without obstructing the blow out of the cool air, increasing the effective area in the room, and making the back surface substantially flat. , The room is refreshing and easy to clean. Moreover, since the cool air flows diagonally in the room, the temperature unevenness in the room is further reduced.

Since the shelf plate is a substantially rectangular glass plate, it is not necessary to process the shelf plate into a complicated shape, and the thickness of the shelf plate is about 5
Since it can be made as thin as about mm, the room can be widely used.

Since the pins are made of metal and the shape of the portion on which the shelves are placed is square, it is possible to sufficiently support the weight of the stored items. Therefore, the size and spacing of the pin holes can be reduced. Therefore, it is possible to finely determine the mounting positions and intervals of the shelf boards.

Since the lighting means is provided in the recessed portion on the door side of the upper surface of the room, the room is illuminated from the door side and the placed object is illuminated from the front side. Moreover, since the shelf plate is a transparent glass plate, it is possible to illuminate the entire room. In addition, compared to the prior art in which a lighting means is provided on the back surface, an object can be placed on the back surface and the effective area is increased, and the back surface can be flattened to make the room cleaner and easier to clean.

Since the automatic ice making device is provided inside the door of the freezing compartment, the area for accommodating food in the room is increased and the interior is refreshed as compared with the prior art in which this is provided in the freezing compartment.

By embedding the rail on the side surface in the vegetable compartment, the side surface does not project, and the width of the drawer case can be widened by this amount to increase the storage capacity.

[0032]
