Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator. More specifically, the present invention relates to a refrigerator capable of preventing dew condensation occurring near the opening of the refrigerator home bar.

Generally, a refrigerator is a device for low temperature storage of food, and is stored in a refrigerator or refrigerated according to a required state of food to be stored, and cold air supplied into the refrigerator is generated by a heat exchange action of the refrigerant.

That is, the cycle of compression, condensation, expansion, and evaporation is repeatedly performed to continuously supply the inside of the refrigerator, and the supplied refrigerant is evenly transferred to the inside of the refrigerator by convection, thereby storing food in the refrigerator at a desired temperature. .

In the main body of the refrigerator, a freezer compartment in which food is stored in a freezer compartment and a refrigerating compartment in which food is stored in a compartment are partitioned by a partition wall, and doors are provided on the front left and / right sides of the main body according to the product type.

In addition, although food, cans, bottles, eggs, and the like are commonly used using a door basket installed on the inner side of the refrigerator door, the storage space of the door basket may be limited.

Recently, refrigerators have been developed to perform additional functions in addition to the basic storage functions according to various demands of consumers. For example, independent auxiliary storage devices exposed outside (commonly referred to as 'home bars'). It can be designed to further include.

Therefore, the auxiliary storage device allows the user to conveniently store or take out various foods without opening the door of the refrigerator.

However, the home bar is provided in the refrigerator door and has a separate home bar door. When the home bar door is opened, the storage stored in the storage space of the home bar can be withdrawn, but the storage space of the home bar is formed by forming an opening in the door of the refrigerator and mounting a shelf on the back of the door, In communication with the interior.

In addition, the inner surface of the home bar door is continuously exposed to cold cold air, thinner than the thickness of the entire door of the refrigerator, and has a structure that can leak the cold air.

Therefore, the temperature around the opening of the home bar door is lower than the ambient temperature, so that dew condensation occurs.

In order to remove the dew condensation phenomenon, a separate heating wire is embedded around the home bar door opening to prevent dew from forming by heating the periphery of the home bar door opening at a constant temperature.

One of the reasons for installing the home bar in the refrigerator is to provide a solution for preventing power loss due to frequent opening of the refrigerator door, in addition to the reason for allowing the user to easily withdraw the stored beverage.

However, according to the experiment, the power consumption of the heater mounted around the opening of the home bar is about 8.5W, and occupies about 12% of the total refrigerator power consumption, so that the home bar is reduced to reduce the power consumption caused by frequent opening of the refrigerator door. It is installed, but it is a waste of power, so there is a need to solve this problem.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the invention is not limited to the embodiments described herein but may be embodied in other forms. Rather, the embodiments introduced herein are provided so that the disclosure may be made thorough and complete, and to fully convey the spirit of the present invention to those skilled in the art. Like numbers refer to like elements throughout.

1 is a simple conceptual diagram of a heat transfer pipe provided in the refrigerator according to the present invention. The heat transfer pipe provided in the refrigerator according to the present invention is filled with a refrigerant R therein and forms a waste flow path.

If heat is not supplied from the outside, the refrigerant is stored in a liquid state under the heat transfer pipe 100. However, when the refrigerant stored in the liquid state inside the heat transfer pipe 100 is supplied with heat Q from the outside, it is endothermic and starts to evaporate. An area receiving heat Q from the outside is defined as a heat absorbing part 110.

The refrigerant R stored in the liquid state in the vicinity of the heat absorbing part 110 absorbs heat and evaporates. The refrigerant R in the evaporated gas state rises from the bottom of the heat transfer pipe 100 to the top to circulate the heat transfer pipe 100.

In addition, the heat transfer pipe 100 according to the present invention is provided with a heat dissipation unit 120 for dissipating heat Q 'to the outside in addition to the heat absorbing unit 110 that absorbs heat from the outside. The heat radiating unit 120 is a section in which the refrigerant evaporated in the heat absorbing unit 110 is condensed through the process of releasing heat to the outside.

The refrigerant circulating through the heat transfer pipe 100 in a gas state is condensed in the heat dissipation unit 120 and condenses in the form of a coolant droplet on the inner wall surface of the heat transfer pipe 100.

The condensed refrigerant droplets are lowered from the inner wall surface of the heat transfer pipe 100 by their own weight, and are then stored as the liquid refrigerant R again.

This process is repeated, and the refrigerant filled in the heat transfer pipe 100 repeats evaporation and condensation, thereby circulating the waste flow path.

Here, the heat absorbing part 110 and the heat dissipating part 120 mean a predetermined section of the heat transfer pipe 100 through which the same refrigerant forming the waste flow path circulates, and thus the heat absorbing part 110 and the heat dissipating part ( 120, the ambient temperature should be different. Therefore, the heat absorbing part 110 and the heat dissipating part 120 are preferably designed to be located at a location where the heat absorbing environment and the heat radiating environment are formed.

The refrigerator according to the present invention uses a heat transfer process using evaporation and condensation of a refrigerant in the heat transfer pipe 100. That is, it absorbs heat Q, dissipates heat Q 'to another place, and transfers heat.

The present invention relates to a method that can replace a hot wire buried around a home bar opening of a conventional refrigerator.

Therefore, the heat dissipation unit 120 of the heat transfer pipe 100 is preferably set to be arranged around the opening of the groove bar.

When the heat dissipation unit 120 is disposed to surround the groove bar opening, a heat dissipation process may be performed around the opening of the groove bar to increase the temperature around the opening of the groove bar, and prevent condensation from occurring. have.

Figure 2 shows an open view of the home bar of the refrigerator according to the present invention. The home bar is provided with a door 240 for selectively opening and closing the receiving space inside the home bar, and is provided by a method of forming an opening 225 in the refrigerator door.

The opening 225 is formed in the refrigerator door, and the storage space inside the home bar communicates with the inside of the refrigerator, and thus has a structure in which cold air can be exposed through the opening 225. Therefore, a rubber gasket 227 may be provided to block cold air that may leak into the gap between the home bar door 240 and the opening 225.

Therefore, the temperature around the gasket 227 will be cooled by the refrigerator indoor air, and dew condensation may occur around the gasket 227. Therefore, in order to prevent such dew formation, the heat dissipation part 120 described in FIG. 1 may be buried around the opening 225 of the groove bar. The heat dissipating unit 120 heats the heat sucked from another place to increase the temperature of the cooled portion rather than the indoor air.

When heat is radiated from the heat radiating unit 120 and the temperature near the opening 225 of the home bar is increased, the relative humidity of the ambient air may be lowered, thereby preventing dew condensation. Hereinafter, an embodiment of a heat transfer pipe that may be provided in a refrigerator according to the present invention will be described with reference to FIGS. 3 and 4.

3 is a front view and a side view of the refrigerator 200 according to the present invention. The refrigerator 200 includes a main body 230 having a storage space, doors 210 and 220 for selectively opening and closing the storage space inside the main body 230, a home bar provided in the door, and an opening of the home bar ( 225) includes a heat transfer pipe 100 embedded in the door to surround the circumference and filled with a predetermined amount of refrigerant to form a waste flow path.

The heat transfer pipe 100 is provided in a manner that is embedded in the door of the refrigerator having a home bar. In the embodiment shown in Figure 3, the home bar is provided on the refrigerator compartment door 220.

In the front view shown in FIG. 3A, the heat transfer pipe 100 is embedded in the door 220 to surround the opening 225 formed in the door 220 to form the groove bar.

In addition, the heat transfer pipe 100 is preferably embedded in the door 220 so that its depth is changed. The reason why the buried depth is changed is to adjust the heat absorbing portion of the heat transfer pipe 100, that is, a section for absorbing heat from the outside, to the buried depth.

The door 220 of the refrigerator performs a function of selectively opening and closing the storage space provided in the main body 230 and insulating the storage compartment and the outside. Therefore, the inner surface of the door 220 is exposed to the low temperature refrigerating chamber, and the front surface is exposed to the outside air at room temperature.

Therefore, it is preferable that the place where the heat transfer pipe 100 absorbs heat is an access section contacting or approaching the inner wall surface of the housing of the door 220. The access section 115 may absorb heat from the outside when the access section 115 is buried in close proximity to the inner wall surface of the door housing. Therefore, the access section 115 may serve as an endothermic portion of the heat transfer pipe 100.

The access section 115 may be located on the inner wall surface of the front or side of the housing of the door 220. Since the front or side surface of the housing 220 is exposed to the outside air, the heat transfer pipe 100 may absorb heat.

In the embodiment shown in FIG. 3, the contact section 115 is provided on the side of the door.

As shown in the side view of the refrigerator according to the present invention shown in Figure 3 (b), the heat transfer pipe 100 provided in the refrigerator may have a bent portion in the contact section 115.

The bent portion is a bent portion of the contact section 115 in order to increase a section in which the heat transfer pipe 100 absorbs heat. As shown in Figure 3 (b), the access section 115 located on the side of the heat transfer pipe 110 embedded in the door 220 of the refrigerator according to the present invention is repeatedly bent to the door 220 housing It is embedded to contact or approach the inner surface of the side surface.

Since the access section 115 acts as an endothermic portion absorbing heat from the outside, the liquid refrigerant stored in the lower portion of the access section 115 evaporates in the access section 115 and circulates in the counterclockwise direction. do.

The shape of the bent portion formed in the access section 115 is shown in the embodiment shown in Figure 3 a straight bent portion, but there is no limitation of the shape. That is, the shape may be configured in various ways such as a straight line or a curve.

The bent portion may be formed in the entire access section 115, or may be formed only in some sections.

And, the heat transfer pipe 110 as shown in the side view of the refrigerator according to the present invention shown in Figure 3 (b), to prevent dew condensation formed in the vicinity of the opening 225 for forming the home bar of the refrigerator. For this reason, it is preferable to be embedded in the housing near the opening.

Although not shown in FIG. 3, a rack or the like forming a storage space of a groove bar may be provided inside the opening, and since the opening has a structure in communication with the inside of the main body 230, the opening 225 is close to the opening 225. The temperature of is lower than the access section 115.

Therefore, the heat absorbed in the access section 115 is condensed in the heat transfer pipe 110 surrounding the opening 225, the dotted line section of the heat transfer pipe 110 shown in Figure 3 (b). It can be stored in the liquid state by descending to the side (part corresponding to the reference numeral 117). The section indicated by the dotted line is not buried in contact with or close to the inner surface of the door front housing or the side housing like the access section 115. It is preferable that the condensed refrigerant is buried inside the door so as not to evaporate.

4 shows another embodiment of a refrigerator according to the invention. The embodiment shown in Figure 4 is that the access section 115 in contact with or close to the inner wall surface of the housing of the door 220 is located below the inner surface of the front of the door 220, not the side of the door There is a difference.

In the embodiment shown in FIG. 4, the access section 115 may be disposed to contact or approach the inside of the front surface of the door 220 housing. The section in which the liquid refrigerant may endotherm from the outside may be extended from the access section 115 of the embodiment shown in FIG. 3.

In addition, in the embodiment illustrated in FIG. 4, the access section 115 may have a bent portion in which the heat transfer pipe 110 is bent, as in the embodiment illustrated in FIG. 3. In FIG. 4, unlike the embodiment illustrated in FIG. 3, the bent portion is illustrated in a curved shape. Description of other operations and effects is the same as the embodiment shown in FIG.

In the above-described embodiments, the heat transfer pipe 110 wraps around the opening 225 for the formation of the groove bar, and condensation occurs by using heat to radiate heat while the refrigerant evaporated around the opening 225 is condensed. To prevent.

In addition, in the embodiment illustrated in FIGS. 3 and 4, the heat to be radiated is absorbed from the outside. The endothermic method was used.

However, even if it is not the front or side of the door housing, if the temperature is higher than the storage space inside the refrigerator can be used as the heat absorbing portion. For example, a refrigerator compressor or the like may be provided, and a method of allowing the heat transfer pipe 110 to pass through an electric compartment (not shown) or the like provided under the rear of the main body 230.

The heat transfer pipe 110 via the electric compartment may be connected to the electric compartment via the hinge assembly side rotatably supporting the door 220 for selectively opening and closing the storage space provided in the main body 230. .

When the heat transfer pipe 110 is made of a metal material having high heat transfer efficiency, a portion of the heat transfer pipe 110 passing through the hinge side may be a plastic pipe that can be easily bent.

Since the temperature of the electric compartment is higher than the temperature of the outside air due to heat radiated from the compressor, etc., the endothermic efficiency may be more excellent.

Although the present specification has been described with reference to preferred embodiments of the invention, those skilled in the art may variously modify and change the invention without departing from the spirit and scope of the invention as set forth in the claims set forth below. It could be done. Therefore, it should be seen that all modifications included in the technical scope of the present invention are basically included in the scope of the claims of the present invention.
