Abstract
A refrigerator with a home bar. The refrigerator reuses waste heat emitted from the electrical units (e.g., compressor and condenser) to heat the home bar frame, thereby preventing or reducing dew formation thereon. An air flow path is coupled to the machine room to supply air that is heated by the waste heat from the machine room to the home bar frame.
Description
- This application is based on and claims priority from Korean Patent Application No. 10-2016-0042819, filed on Apr. 7, 2016, the disclosure of which is incorporated herein in its entirety by reference for all purposes.
- The present disclosure relates to refrigerators and hot air transferring units provided for the same, and more particularly, to home bar systems on refrigerators.
- Refrigerators are electrical appliances capable of maintaining a storage chamber below room temperature. Food or other objects can be stored in a refrigerator in a cold or frozen state. The space inside the refrigerator is maintained at a low temperature by cool air circulation. Cool air is continuously generated through a refrigeration cycle including compression, condensation, expansion and evaporation. Cool air is distributed to the inner space of the refrigerator by convection.
- An upright type refrigerator has a freezer and a refrigerating chamber, one disposed above the other. A parallel type refrigerator typically has a relatively large capacity, and the freezer and refrigerating chamber are disposed side by side.
- Some refrigerators include a built-in home bar which enables a user to take out a stored object without having to open the refrigerator door. The door of the home bar may be rotatably installed in the refrigerator door. A storage space, e.g., a home bar compartment or the like, is formed on a rear surface of the refrigerator door in a region behind the home bar door. To take out an object stored in the home bar case, a user may simply open the home bar door without opening the refrigerator door. By keeping the refrigerator door closed, the amount of room temperature air entering the refrigerator can be reduced and so overall power consumption to cool the contents in the refrigerator can be reduced.
- However, as the home bar frame has a lower temperature than the air outside the refrigerator (or room temperature air), moisture in the room temperature air tends to condense on the home bar frame and forms dew.
- In the related art, a heater is mounted around the home bar frame to prevent dew accumulation around the home bar frame. However, heat generated by the heater can be inevitably transferred to the interior of the home bar and raise the temperature inside the refrigerator. As a result, additional electric power is consumed to maintain a cold temperature in the refrigerator, which unfortunately counteracts the purpose of using the home bar.

FIGS. 1 to 4 , theexemplary refrigerator 10 may include amain body 100,main doors 200, a home bar opening 300, ahome bar frame 310, ahome bar door 320, amachine room 400 and a hotair transferring unit 500. - The inclusion of the aforementioned components in one embodiment of the present disclosure does not mean that one embodiment of the present disclosure consists of only the aforementioned components but means that one embodiment of the present disclosure basically comprises these components. One embodiment of the present disclosure may further comprise other components that are well known in the art. The well-known components are not described herein for brevity.
- The
main body 100 constitutes an overall housing of therefrigerator 10. At least onestorage room 110 is formed within themain body 100. For instance, thestorage room 110 is divided into a freezer at one side of themain body 100 and a refrigerating chamber at the other side. - The
main doors 200 may be rotatably coupled to themain body 100 and cover the storage room. There may be one or moremain doors 200 on the refrigerator. For instance, the main doors respectively cover the refrigerating chamber, the freezer and anotherstorage room 110. - The home bar opening 300 extends through a front surface of a main door and allows a user to access the
storage room 110 or anotherindependent space 301 without opening the main door. Theopening 300 may be located on one of themain doors 200, e.g., a refrigerating chambermain door 200. Thus, an object can be place in, or taken out from, the refrigerator through theopening 300. Using the home bar can significantly reduce room temperature by reducing an amount of air flowing from the outside of the refrigerator to the inside due to the much smaller size of the home bar opening 300 than the size of the outer surface of each of themain doors 200. - The
home bar frame 310 may be disposed around theopening 300. Thehome bar door 320 may be hingedly coupled to thehome bar frame 310. - The
machine room 400 may be located close to a side of themain body 100.Electrical drive units 410 are installed inside themachine room 400. Theelectrical drive units 410 operate to generate cool air to be supplied to the storage room to maintain a low temperature therein. As illustrated inFIGS. 2 and 4 , themachine room 400 is located in a lower rear portion of themain body 100 and extends along the transverse direction of themain body 100. Themachine room 400 provides an accommodation space for thedrive units 410. - The
machine room 400 has a higher temperature than the storage rooms of the refrigerator because of waste heat generated and emitted from thedrive units 410 located therein. More specifically, thedrive units 410 may include acompressor 411, acondenser 412 and the like and operate to generate cool air in refrigeration cycles. Thecompressor 411 and thecondenser 412 may produce and emit a large amount of heat during the course of their operation. In the related art, such heat is unused and dissipated to the outside. - According to embodiments of the present disclosure, the waste heat from the machine room can be used to reduce or remove moisture condensation (or dew) around the home bar.
- More specifically, a hot
air transferring unit 500 is used to transfer the waste heat generated in themachine room 400 to thehome bar frame 310. The hotair transferring unit 500 may include anair flow path 510. As illustrated inFIG. 2 , theair flow path 510 may obliquely extend from a lower rear side of themain body 100 to an upper front side of themain body 100 where thehome bar frame 310 is located. Air in themachine room 400 is heated by the waste heat emitted from thedrive units 410 and therefore tends to flow upward along the air flow path. Thus, the waste heat generated in themachine room 400 may be transferred to thehome bar frame 310 through the air flow along theair flow path 510. - In this example, the
machine room 400 extends along the transverse direction of themain body 100. Anintake fan 420 can be installed at the end of theair flow path 510 that is coupled to themachine room 400. The fan can increase the air flow in the air flow path and thereby increase the heat transfer rate. - More specifically, as illustrated in
FIG. 2 , one end of theair flow path 510 may be coupled to one side of an upper portion of themachine room 400. The other end of theair flow path 510 may be coupled to an upper surface of thehome bar frame 310. As illustrated inFIGS. 3 and 5 , a plurality of injection holes 520 are formed at one end of theair flow path 510 and proximate to thehome bar frame 310. Through the injection holes 520, hot air exiting from the air flow path is distributed to the home bar frame and thereby heats up or warm the home bar frame. Further, the injection holes 520 are spaced apart from each other and may be formed on theupper surface 311 of thehome bar frame 310. -
FIG. 5 is an enlarged sectional view of a region designated by “A” inFIG. 2 .FIG. 6 is an enlarged sectional view of a region designated by “B” inFIG. 3 wherein the main door is in a closed position.FIG. 7 illustrates that the main door is in an open position. - Referring to
FIG. 5 , ahome bar gasket 312 may be installed in thehome bar frame 310, facing an inner surface of thehome bar door 320. As illustrated inFIG. 1 , thehome bar gasket 312 may surround thehome bar frame 310, e.g., in conformance with the shape of thehome bar frame 310. Thehome bar gasket 312 can seal the gap between thehome bar frame 310 and thehome bar door 320 to prevent external air from flowing into the refrigerator through thehome bar opening 300. This helps maintain the low temperature inside the refrigerator. - As illustrated in
FIGS. 6 and 7 , the hotair transferring unit 500 may include abellows tube 530 which is extendable. Thebellows tube 530 is coupled to the air flow path and between themain body 100 and themain door 200. - The
main door 200 covers thestorage room 110. Thus, as illustrated inFIG. 6 , when themain door 200 is closed, there is a certain gap (hereinafter referred to as “door gap”) between themain door 200 and themain body 100. As illustrated inFIG. 7 , when themain door 200 is open, the door gap is enlarged. - Thus, when the door is open, the
air flow path 510 is disconnected. In the present embodiment, thebellows tube 530, having an extendable length, is installed in the door gap. When themain door 200 is closed as illustrated inFIG. 6 , thebellows tube 530 is compressed and pressed against themain door 200 so that theair flow path 510 becomes continuous. Thus, air carrying the waste heat can be transferred through theair flow path 510 without leaking to the outside and eventually supplied to thehome bar frame 310. - When the
