Description

Refrigerator door pocket

The present invention relates to a refrigerator, and more particularly, a door pocket provided on the inner surface of a door of a small refrigerator manufactured by blow molding, and mainly for storing and storing bottled foods. It is about.

As is well known, a refrigerator is a household appliance used to freeze and / or refrigerate food by heat of evaporation of a refrigerant using a cooling cycle, and as shown in FIG. 1, a cavity The food stored therein is frozen by installing an evaporator (4) at the rear of the container (2) and circulating the cooled air by the fan (5) to the cavity (2) of the cabinet (1). And / or refrigerated.

Accordingly, the entrance of the cabinet 1 is provided with a door 3 for opening and closing the cavity 2 at the time of storing and withdrawing food, while shielding the cavity 2 from the outside. In general, a plurality of door pockets 6 for storing the bottled food D easily are generally provided in layers.

On the other hand, the conventional refrigerator cabinet 1 or the door 3 is assembled with a cover inside the metal panel (panel) to fill the urethane (urethane) foam functioning as a heat insulating material therein, and then inside the cover It has a complicated structure composed by attaching a liner of synthetic resin on the side, making the production very difficult and complicated.

Therefore, recently, in the case of a small refrigerator, a predetermined form is formed by a so-called "hollow molding method" in which a molded article of a sheet or pipe in which two pieces are glued together is put into a mold and blown with air to make a hollow product. After the molding, the cabinet 1 and the door 3 may be manufactured by filling a urethane foam material therein.

Accordingly, in the case of the door 3 made of a synthetic resin material by the blow molding method, as shown in Fig. 2, a pair of beads 3a opposed to each other on both inner surfaces thereof are formed in the vertical direction. The door pocket 6 is formed by providing a wire support 7 for supporting the co-current food D between the pair of leads 3a.

However, such a conventional door (3) is very difficult to configure the height (h) of the bead (3a) for constituting the door pocket (6) for a certain length or more due to the characteristics of the blow molding method, the door pocket (6) There was a problem that the function could not be fully exercised. That is, in the case of a small and medium-sized refrigerator, the fixed end width b1 of the bead 3a is about 15 mm and the free end width b2 is about 10 mm. In this case, the height h of the bead 3a is It is determined within about 30 mm. As shown in FIG. 3, the bead 3a is formed by blowing the preform S into the air G into the groove G of the mold M. The door pocket having a sufficient space under the above conditions ( 6) If the height h of the bead 3a is set to 30 mm or more, the preform S may be torn, such that the bead 3a is impossible to be molded, so that poor manufacturing is frequently performed. Since this is quite awkward, the height h of the bead 3a must be limited to a certain length or less.

Therefore, the conventional door 3 can only store the co-current food D having a diameter within a range that the height h of the bead 3a constituting the door pocket 6 is considerably narrow. The function of the door pocket 6 could not be sufficiently exerted, such that the range of use thereof was extremely limited and the coexistence foods D having various diameters could not be stored effectively.

The object of the present invention is to allow the height of the door pocket for storing bottled foods to be freely set to a desired length in the door manufactured by the blow molding method in view of the conventional problems as described above, and can be manufactured very easily. To provide a door.

In order to achieve the above object, the present invention is made of a synthetic resin material by the blow molding method, is provided on the inside of the refrigerator door filled with a urethane foaming material is a door pocket for storing co-current food, both sides of the inner side of the door Two pairs of bead pairs each having a width greater than the protrusion height of the bead pair having a plurality of bead pairs formed in parallel to each other and arranged vertically on the inner surfaces facing each other and having a width greater than the protrusion height of the bead pair Each base is inserted and fixed to support the bottled food at the bottom and is formed by blow molding method, and is spaced apart by a certain height above the base, and both ends are fixed to the bead pair to support the bottled food from the side. It is characterized by comprising a wire support.

Accordingly, the present invention can freely configure the width of the door pocket to a desired size regardless of the height of the protrusion of the bead, so that it is possible to effectively store concomitant foods of various sizes. It will have a great effect in improving the ease of use.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 and 4 to 6, the illustrated configuration is, for example, an intercooled small refrigerator, in which a cooler 4 is installed on a rear surface of a cavity 2 in which food is stored, and thereby cooled. The circulated air is circulated by the fan 5 to the cavity 2 of the cabinet 1 to freeze and / or refrigerate food stored therein.

Accordingly, the entrance of the cabinet 1 is provided with a door 10 for opening and closing the cavity 2 at the time of storing and withdrawing food, while shielding the cavity 2 from the outside and the inside of the door 10. In the main, a plurality of door pockets 11 are provided in a layered manner for easily storing the bottled foods D.

Meanwhile, the cabinet 1 and the door 10 of the present invention are made of a synthetic resin material using a blow molding method for ease of fabrication, and then filled with a urethane foam material 18 serving as a heat insulating material therein.

Accordingly, the door pocket 11 of the present invention is a pair of beads 12 protruding from the inner surface of the door 10 in parallel to each other and vertically arranged according to the features of the present invention, and between the pair of beads 12 A plurality of bases 13 supporting the co-current foods D from the lower side and spaced apart by a predetermined height are fixed to each other so as to be arranged horizontally so as to be arranged horizontally. It is comprised by the wire support 17 which supports a parallel food product D from the side by being fixed.

The pair of beads 12 are integrally formed at the same time when the door 10 is molded, and the protrusion height h 'is a pair of bead 12 having a preform (S in FIG. 3) constituting the door 10. Due to the configuration of the tearing is set appropriately. On the mutually opposite inner surfaces of the pair of beads 12, coupling grooves 12a into which both ends of each base 13 are inserted are formed at regular intervals.

The base 13 is made of a synthetic resin material by a blow molding method, like the door 10, the width (b) is projected by the pair of beads 12 to accommodate the parallel foods (D) having various diameters It is formed larger than the height h '. Accordingly, one side of the base 13 protrudes more than the pair of beads 12 of the door 10, so that both ends of the base 13 are preferably coupled to each other at the end of the base 13 to which the pair of beads 12 are coupled. ) Are formed respectively.

Preferably, engaging grooves 12b are formed at predetermined positions on the inner surface of the pair of beads 12, respectively, and both sides of the base 13 are resilient to the engaging grooves 12b of the pair of beads 12 on both sides of the base 13. The locking projections 16 which fix the base 13 to the door 10 by being inserted into each other are formed.

Both ends of the wire support 17 are banded in the same direction so as to correspond to the width b of the base 13, and are coupled to the front end surface of the pair of beads 12.

Meanwhile, the door 10 and the base 13 may be configured by filling the urethane foam material 18 in the hollow portions 10a and 13a, respectively, but in this case, the manufacturing becomes complicated. Accordingly, preferably, a plurality of coupling slots 10b communicating with the hollow portion 10a are formed in the horizontal direction on the rear surface of the door 10, and on one main surface of the base 13 in contact with the hollow slot 10a. The connecting pieces 15 inserted into the respective coupling slots 10b of the door 10 with the communication hole 15a communicating with the hollow part 13a are formed to protrude, so that the hollow part 10a of the door 10 can be formed. The filling of the urethane foam material 18 to the hollow portion 13a of the base 13 when filling the urethane foam material 18 is configured to be achieved at the same time.

The connection pieces 15 of the base 13 serve as a connection passage of the urethane foam material 18 between the door 10 and the base 13 as well as serve as a base of the base 13 to the door 10.

When the door pocket 11 of the present invention having such a structural feature is inserted both ends of the base 13 into the coupling groove 12a of the pair of door 10 beads 12 produced by the blow molding method, respectively, Each connecting piece 15 of the base 13 is fitted into the corresponding engaging slots 10b of the inner surface of the door 10, respectively, so that the hollow 10a of the door 10 and the hollow 13 of the base 13 13a) are in communication with each other. At the same time, the locking projections 16 of the base 13 are elastically fitted to the locking grooves 12b of the pair of beads 12 so that the base 13 is fixed to the door 10 and the door pocket ( 11).

In this state, when the urethane foam member 18 is filled in the hollow portion 10a of the door 10, a part of the urethane foam member 18 passes through the communication holes 15a of the connecting piece 15 of the base 13. The hollow portion 13a is also filled at the same time and then solidified to complete the configuration of the door pocket 11 for the door 10. At this time, since the urethane foam material 18 in the door 10 and the hollow part 10a and 13a of the base 13 is integrally connected, the base 13 has the effect of being integrally fixed to the door 10 and thus the door ( The overall stiffness of 10 becomes very large.

Accordingly, the present invention forcibly constitutes a protrusion height h 'of the pair of beads 12 integrally formed in the door 10 to secure a sufficient size of the door pocket 11, as conventionally, beyond the allowable limit. It is possible to form a sufficient size of the door pocket 11 without having to. Accordingly, it is possible to effectively prevent the production failure such as the bead 12 is torn during the molding of the door 10, as well as to facilitate the manufacture of the door 10.

As described above, according to the present invention, the door pocket for storing co-current foods in a door made of synthetic resin by the blow molding method can be easily configured in a sufficient size to easily accommodate co-currents of various sizes, Accordingly, the present invention has an excellent effect that can greatly improve the production and ease of use of a small refrigerator made of a synthetic resin material by the blow molding method.
