Description

Refrigerator {A refrigerator}

The present invention relates to a refrigerator.

In general, a refrigerator is a device for low temperature storage of food, and is configured to freeze or refrigerate food according to the type of food to be stored.

The inside of the refrigerator is cooled by continuously supplied cold air, and the cold air is continuously generated by the heat exchange action of the refrigerant by a refrigeration cycle undergoing a process of compression-condensation-expansion-evaporation. The cold air supplied to the inside of the refrigerator is evenly transferred to the inside of the refrigerator by convection, so that food in the refrigerator can be stored at a desired temperature.

The refrigerator main body has a rectangular parallelepiped shape with an open front surface, and includes a refrigerating chamber and a freezing chamber inside the main body. The front surface of the main body includes a refrigerator compartment door and a freezer compartment door for selectively shielding the opening.

In addition, the storage space inside the refrigerator is provided with a plurality of drawers, shelves and storage boxes for storing various foods in an optimal state. In addition, a plurality of baskets are provided on the rear of the doors. The storage space inside the refrigerator is partitioned by the shelves, storage boxes, and baskets such that suitable foods can be stored.

Meanwhile, a gasket for sealing the inside of the refrigerator is provided at an edge of the door. Since the freezing compartment and the refrigerating compartment are sealed by the gasket, the cold air does not flow out to the outside to maintain a low temperature.

In detail, the gasket generally includes a magnetic material therein to allow the door to be in close contact with the main body. In addition, the gasket is provided with a soft material such as rubber, and is compressed by the pressure difference between the magnetic force and the storage space and the external pressure acting between the magnetic body and the main body to be in close contact with the main body and the door. Thus, no gap is created between the main body and the door. At this time, the magnetic material is formed flat so that the gasket is in close contact with the main body.

However, the above conventional technologies have the following problems.

Since the inside of the refrigerator generally has a lower temperature of the air than the outside, a low pressure atmosphere is formed. Therefore, when time passes while the door is closed, a pressure difference occurs between the outside and the inside of the refrigerator, and thus the door is in close contact with the main body.

Therefore, when the door is to be opened, there is a problem in that a relatively large force is required because a force greater than the combined force of the adhesion force due to the magnetic body and the force due to the pressure difference is required.

In particular, housewives who frequently use the refrigerator have a relatively weak power, and thus suffer from great inconvenience due to the large opening force.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a refrigerator in which a door can be easily opened and a leak of cold air is prevented.

The refrigerator according to an embodiment of the present invention for achieving the object as described above is provided with a storage space for storing food at low temperature; A door rotatably provided on the main body to selectively shield the storage space; And a gasket provided along an edge of the door and shielding a space between the door and the main body, wherein the gasket includes: a gasket body; A fixing part extending to a rear side of the gasket body and inserted into the door; It characterized in that it comprises a magnetic body provided on the front end of the gasket body to be in close contact with the main body, the magnetic body is provided with a magnetic body formed with at least one projection protruding toward the main body.

According to the refrigerator according to the embodiment of the present invention as described above, the structure of the door gasket is improved, there is an advantage that the opening of the door is made easy and at the same time prevent the leakage of cold air.

Hereinafter, with reference to the drawings will be described in detail a specific embodiment for implementing the spirit of the present invention.

1 is a perspective view showing the internal configuration of a refrigerator according to an embodiment of the present invention.

Hereinafter, in order to explain the idea of the present invention, a side by side type refrigerator will be described as an example. However, the idea of the present invention is not limited to the illustrated double door refrigerator, and is applicable to both a top mount type in which a freezer compartment is located at an upper side and a bottom freeze type in which a freezer compartment is located at a lower side thereof. To reveal.

Referring to FIG. 1, a refrigerator 1 according to an exemplary embodiment of the present invention includes a main body 10 partitioned into a freezer compartment 12 and a freezer compartment 13 by a barrier 11, and a front surface of the main body 10. And a freezer compartment door 14 rotatably mounted to the freezer compartment 14 to selectively open and close the freezer compartment 12, and a refrigerating compartment door 15 to selectively open and close the refrigerating compartment 13.

In addition, a plurality of shelves 16 and a plurality of storage boxes 17 are provided in the storage space inside the main body 10, and foods may be stored in the rear surfaces of the freezer door 14 and the refrigerating chamber door 15. A number of baskets 18 are provided. In the basket 18, foods such as cheese and butter may be stored in foods that are deteriorated in quality or are discolored or damaged due to evaporation of moisture when they are excessively exposed to cold while maintaining a low temperature.

By means of food storage means such as shelves, storage boxes, baskets, and the like, the user can conveniently store and withdraw food, and can efficiently use the internal space of the refrigerator.

On the other hand, the door gasket 20 is formed on the rear surface of the doors 14 and 15 along the edge of the doors 14 and 15. The gasket 20 serves to block the inflow and outflow of air from the freezer compartment or the refrigerating compartment and the outside shielded by the doors 14 and 15. Hereinafter, a gasket provided in the refrigerating compartment door 15 will be described as an example.

Since the cold air inside the refrigerator 1 does not leak to the outside by the configuration as described above, food can be cooled and stored at an appropriate temperature.

2 is a cross-sectional view of the door gasket of the refrigerator according to the embodiment of the present invention.

Referring to FIG. 2, the gasket 20 includes a gasket body 210 in which a magnetic body 230 having a magnetic body 240 is formed, and a gasket body 210 connected to the gasket body 210 to prevent leakage of cold air. A part 220 and a fixing part 250 for fixing the gasket body 210 to the door 15 are included.

In detail, the gasket 20 is formed to shield a gap between the main body 10 and the door 15 in the state in which the door 15 is closed. Therefore, the gasket 20 is formed along the edge of the door 15 facing the main body 10 on the rear surface of the door 15, and the main body 10 in the state in which the door 15 is closed. Close to) That is, since the gasket 20 is provided, cold air inside the refrigerating compartment is not leaked to the outside.

The gasket body 210 is formed of a soft member such as rubber. Therefore, when the door 15 is closed, when the pressure due to the temperature difference between the inside and the outside of the refrigerating chamber is applied to the door 15, the gasket body 210 is compressed. That is, since the gasket 20, the door 15, and the main body 10 are in close contact with each other, the cold air leakage preventing effect becomes more excellent.

In addition, an air pocket 260 is formed inside the gasket body 210 to cushion the shock that may occur in the process of closing the door 15.

On the rear end of the gasket body 210, a fixing part 250 inserted into the fixing groove 151 formed in the door 15 is protruded. In detail, the fixing groove 151 is formed in the inlet is narrower than the inside, the fixing portion 250 is formed narrower toward the rear end, the rear end of the fixing portion 250 groove hook 251 of the shape that is open to both sides ) Is provided. Therefore, when the fixing part 250 is elastically deformed and inserted into the fixing groove 151, the groove hanger 251 is caught by the inlet of the fixing groove 151, so that the gasket 20 is the door ( 15) is fixed.

In addition, the gasket body 210 is provided with a cold air leakage preventing unit 220 in the inward direction of the door 15. The leakage preventing part 220 is formed of a soft member to be in close contact with the main body 10 in the state in which the door 15 is closed. In detail, the front of the leakage preventing part 220 is in close contact with the main body 10, the rear is in close contact with the door 15. In addition, the leakage preventing part 220 is formed to extend to the side of the gasket body 210 so that the area in close contact with the main body 10 and the door 15 is increased. By the above configuration, the cold air of the refrigerating compartment is primarily blocked by the leakage preventing unit 220.

On the other hand, a magnetic body 230 is provided at the front end of the gasket body 210. The magnetic body 240 is provided inside the magnetic chamber 230 to maintain the state in which the door 15 is in close contact with the main body 10 by magnetic force. In addition, the main body 10 in close contact with the magnetic body 230 is formed of a metallic member. That is, when the door 15 is closed, the attraction force acts between the magnetic body 240 and the main body 10. Therefore, the door 15 is in close contact with the main body 10 and remains closed until the user applies a force to open the door 15. Here, the magnetic body 240 may be adhesively mounted inside the magnetic chamber 230. In addition, the magnetic chamber 230 is formed to be long in the left and right directions of the door 15 so that the magnetic force of the magnetic body 240 fully acts on the body 10, the area in which the magnetic force of the magnetic body 240 acts. It is formed to be wider.

The magnetic body 240 is formed to correspond to the shape of the magnetic chamber 230, and at least one magnetic protrusion 241 protrudes from the front surface thereof. That is, the portion of the magnetic body 240 closest to the body 10 is the magnetic protrusion 241. Since the magnitude of the magnetic force acting between the two objects is inversely proportional to the square of the distance, the strongest attraction force acts between the magnetic protrusion 241 and the main body 10.

On the other hand, by providing the magnetic protrusion 241, the area of the portion that applies the strongest attraction to the main body 10 is reduced. Therefore, the coupling force between the door 15 and the main body 10 is reduced. In detail, since the magnetic protrusion 241 is located close to the main body 10, a strong attraction force is applied, and a portion between the magnetic protrusions 241 has a relatively small attraction force. That is, a smaller force is applied between the main body 10 and the door 15 than when the magnetic body is formed flat so that the whole is in close contact with the main body. Thus, the user can open the door 15 with less force.

In this case, the main body 15 may be formed to correspond to the shape of the magnetic body 240. For example, when the front end portion of the magnetic protrusion 241 is formed flat, the main body 15 may protrude at the same position to correspond to the magnetic protrusion 241. In this case, since the distance between the portion excluding the magnetic protrusion 241 and the main body 10 becomes further, the coupling force between the main body 10 and the door 15 becomes weaker. Therefore, the door 15 can be opened more easily.

In addition, the front end portion of the magnetic protrusion 241 may be provided flat. In this case, since the area in which the magnetic body chamber 230 is in close contact with the main body 10 increases, it is possible to further improve the cold air leakage prevention effect.

In addition, when a plurality of the magnetic protrusions 241 are provided, a portion in close contact with the magnetic protrusions 241 of the magnetic body 230 may be formed to be constantly maintained. For example, the front end portion of the magnetic protrusion 241 may be attached to the magnetic chamber 230. In this case, even if the gasket 20 is compressed by the pressure difference between the refrigerating chamber and the outside after the door 15 is closed, the space between the magnetic protrusions 241 is maintained. That is, an empty space between the main body 20 and the magnetic body 230, which may occur due to the deformation of the magnetic body 230, may not be formed. Therefore, the airtightness of the refrigerating compartment can be maintained more firmly, so that the cold air does not leak.

The refrigerator 1 according to the exemplary embodiment of the present invention having the above configuration has a protrusion structure formed at the front end portion of the magnetic body 240 mounted to the gas kettle 20, thereby acting on the main body 10. The opening of the door 15 can be easily made by reducing the size of the attraction force.

In addition, by maintaining a space between the magnetic projections 241, there is no gap between the magnetic chamber 230 and the main body 10, there is an effect that the cold air leakage of the refrigerating chamber is prevented.

The scope of the present invention is not limited to the above-described embodiments, and the embodiments may be changed, added, or deleted within the scope of the spirit of the present invention.
