Description

Double door refrigerator {Double door refrigerator}

Many kinds of refrigerators are commercially available and studied today, and the study is mainly conducted according to the inherent characteristics of refrigerators, which can maintain the freshness of foods stored and stored for a long time in the refrigerating chamber or the freezer for a longer time. The focus is on the more efficient use of energy.

As a means to solve this problem, among the refrigerators currently on the market, a method of preserving the cold air in the refrigerating chamber by forming a so-called 'cooling curtain' temporarily flows out where the door was when the refrigerating chamber door was opened. There is adoption. However, in such a refrigerator, a separate system for supplying cold air quickly when the refrigerator door is opened must be operated, whereas even if such a system is operated, it is actually a structure in which newly supplied cold air is exposed to the surroundings when the door is opened. Therefore, the use of new cold air is not necessarily made efficiently.

As another method, there is a method of dividing a refrigerator into spaces and adopting a plurality of spaces and a separate door in one refrigerator. However, this method may increase the energy efficiency of the entire refrigerator by spatially dividing the refrigerator, but still has the same problems as conventional refrigerators in terms of preserving cold air in the open door. have. In addition, such a refrigerator cannot ignore the reduction of the spatial efficiency according to the space division, and thus it is mainly a form that can be adopted only in a large refrigerator.

Unlike the spatial separation that adopts a separate space and a separate door as described above, only one door of the refrigerating chamber, like the existing refrigerator, is installed, and the refrigerating chamber, which is the space inside the door, is used to keep the vegetables below. The partitions are also provided in the form of drawers, which are generally installed in the space, so that the cold air of the refrigerating compartment can be preserved even when the door is opened. However, in this method, the process of taking out or storing food from these drawer-type refrigerators is a little cumbersome, the food to be found may not be found quickly, and the storage of bulky containers, etc. may be restricted. There are many inconveniences in actual use.

On the other hand, some refrigerators are equipped with a dispenser outside the refrigerator door so that only the coolant or ice can be used without opening the door of the refrigerator. However, the refrigerator can be used only for limited uses for water or ice, and its use range is very limited. It is not an advantageous form in terms of manufacturing cost since a separate complicated device is required.

The present invention is to provide a refrigerator of a completely different type from the conventional refrigerator, and to provide a refrigerator that can more efficiently cut off the cold air in the refrigerating compartment and further increase energy efficiency when the refrigerator door is opened. .

The present invention is, in particular, the main object of opening the refrigerating compartment door in order to take out water, beverages and the like, in addition to the pocket portion provided on the door side, the cold air of the refrigerating compartment body can be efficiently stored.

That is, the present invention focuses on the fact that the frequency of using the pocket portion mounted on the door side of the refrigerator functioning to store beverages is much higher than the frequency of use of the refrigerating chamber itself for storing stocks. In the case of opening and closing the door of the refrigerating compartment to drink water or beverage in addition to the purpose of taking out the water, the refrigerator is provided so that only the pocket part of the refrigerator door is exposed to the outside air and the cold air in the refrigerating compartment main body can be efficiently blocked and preserved. will be.

As a means for achieving the above object, the present invention provides a refrigerator equipped with a double door, another door is mounted in a conventional refrigerator door.

That is, the present invention interposes another door, that is, an inner door, between the door of the existing refrigerator and the refrigerating chamber, without greatly deforming the conventional refrigerator form, and the space of the inner pocket part of the outer door between the outer door and the inner door. The cold air flows through the cooling air supply port formed in the separate cooling duct and the inner door, so that only the outer door is opened to use the pocket part mounted on the refrigerator door to drink water or beverage, In order to use the internal space of the refrigerator compartment to take out the same stock, the internal and external doors are opened at the same time so that the temperature of the refrigerator can be minimized to maintain the freshness of the food and improve energy efficiency. It is characterized by the provision of a new method.

Here, the inner door may be attached and sealed to the refrigerator main body by a magnet mounted along the edge of the inner door, the outer door may be attached and sealed to the inner door by a magnet mounted along the edge of the outer door. The hinge for opening and closing the inner door operates on the same axis, and the outer door can be opened and closed independently, and the magnetic force between the inner door and the refrigerator main body is stronger than the magnetic force between the outer door and the inner door, making it easy to open and close the outer door only. In addition, when the door is opened by pulling the handle of the inner door, the outer door and the inner door are opened by being integrated with a magnet, so when the door is pulled open, the pocket between the outer door and the inner door is opened. Only the subspace is exposed to the ambient air, and if you pull the inner door knob open, only the internal space of the main body There are those characterized by employing a scheme such that Ex.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

1 is a schematic side cross-sectional view of a refrigerator according to an embodiment of the present invention, Figure 2 is a front view of the drawing.

As can be seen from these figures, the shape of the outer door (2, 2 ') of the refrigerator provided with the double door of the present invention is not significantly different from the shape of the existing refrigerator, but another door (3, 3) therein ') Is installed so that the outer doors 2,2' are hermetically attached to the inner doors 3,3 'by magnets 8,8' mounted along the circumference of the outer doors 2,2 '. And the inner doors 3 and 3 'are hermetically attached to the refrigerator body by magnets 9 and 9'.

The material of the inner doors (3, 3 ') can be appropriately selected according to the purpose, but the food contained in the interior space (5) of the refrigerator main body is identified even when only the outer doors (2,2') are opened by using a material such as transparent acrylic. It is desirable to be able to.

As mentioned above, the magnetic force of the magnets 9, 9 'mounted on the inner doors 3, 3' is higher than the magnetic force of the magnets 8, 8 'mounted on the outer doors 2, 2'. In addition to the easy opening and closing of the outer door (2,2 '), when pulling the inner door handle (7,7'), the outer door (2,2 ') and the inner door (3,3') It becomes a structure which is opened together in an integrated state by magnetic force.

When the refrigerator door is completely closed, the space between the inner space (5, 5 ') of the refrigerator body and the space of the pocket portion (4, 4') between the outer door (2, 2 ') and the inner door (3, 3') An appropriate number of cold air holes 10 may be formed at an appropriate position on the inner doors 3 and 3 'to allow the cool air to pass through, but internal cooling of the pockets 4 and 4', which are frequently in contact with the outside air, It is preferable to connect another cooling duct (not shown).

This figure shows that the double doors of the outer and inner doors are installed in both the refrigerator compartment (A) and the freezer compartment (B) of the existing refrigerator, but it is less necessary to install such double doors for the freezer compartment (B), which has a low use frequency of the pocket part. Therefore, the double door may be provided only in the refrigerating chamber A, or, depending on the special purpose, the double door may be selectively installed in either the refrigerating chamber A or the freezing chamber B.

As shown in Figure 2, the handle portion for opening and closing the refrigerator door of the present invention, in the case of the outer door (2) of the refrigerating chamber (A) frequently used, the handle portion (6) protrudes to the outside so that children can easily open and close It will be installed in the longitudinal direction, the inner door (3) opening and closing handle portion 7 will be convenient to install in the transverse direction at the top.

However, the shape of the handle portion is not particularly limited to the shape as long as the double door of the present invention can be opened and closed as intended in the present invention.

According to the configuration of the invention as described above, while installing the double doors of the outer door (2,2 ') and the inner door (3,3') that can be opened and closed independently of the existing refrigerator, the outer (2,2 ') The refrigerator is much more frequently used by opening and closing more easily than the inner doors 3 and 3 'and by allowing the inner doors 3 and 3' to be opened and closed mainly with the outer doors 2 and 2 '. When the door side pocket part 4 is used, the cold air of the refrigerating compartment main body space 5 can be efficiently interrupted by the inner door 3.

According to the configuration as described above, the refrigerator of the present invention shows a remarkable effect in blocking the cold air of the refrigerating compartment even if the refrigerator door is frequently opened and closed to drink water or beverages, thereby minimizing the temperature change in the refrigerating compartment to save power. In addition, the freshness of the food can be kept longer.

In addition, the refrigerator of the present invention has a function to effectively block the odor generated by the food stored in the internal compartment of the refrigerator compartment, and when applied to the freezer compartment, it is possible to store ice cakes with high adsorption power in the freezer compartment pocket separately. Hygiene can be stored hygienically to prevent the odor generated from frozen foods, and if the ice maker is installed in the freezer pocket part by applying it, the smell of other food is not discharged from the ice produced as compared with the installation of the ice maker in the freezer body space. You can also make fresher ice.

Although the object of the present invention is mainly in terms of preservation of the cold air in the refrigerating compartment body internal space 5, when the inner door 3 is opened for use of the refrigerating compartment body internal space 5, the inner door 3 is an external door. Since it is opened integrally with (2), the cold air of the pocket part 4 is also blocked at this time, and the additional effect of blocking the cold air to the unused space is generated.

As described above, the present invention by introducing the inner door (3) between the refrigerator body (1) and the outer door (2), while effectively blocking the cold air in the interior space (5) of the refrigerator compartment main disadvantage It can be seen that it is possible to provide an entirely new type of refrigerator, which is very convenient to use and advantageous in terms of production cost.
