[25]
[26] *Ref erring to FIGS. 1 to 3, the refrigerator according to the present invention will be described with reference to, as one preferred embodiment, a bottom freezer type wherein a refrigerating chamber is provided on an upper side and a freezing chamber is
provided on a lower side.
[27]
[28] *Specifically, the refrigerator 10 according to one embodiment of the present invention comprises a main body 11 having a refrigerating chamber 15 and a freezing chamber 16 provided on an upper side and a lower side, respevtively, a door 12 for the refrigerating chamber opening and closing the refrigerating chamber 15, a door 13 for the freezing chamber opening and closing the freezing chamber 16. In detail, the refrigerating chamber 15 and the freezing chamber 16 are separated by a barrier 111.
[29] Also, one side surface of a ceiling of the refrigerating chamber 15 is provided with a ice maker 20 and a cooling duct 18 is extended along wall and celing surfaces of the refrigerating chamber. And, the door 12 for the refrigerating chamber is rotatably installed at front surfaces of the left and right of the main body 11, respectively. And, a dispenser 14 capable of dispensing water and ice is installed at any one front surface of the door 12 for the refrigerating chamber 12.
[30] On the other hand, the door 13 for the freezing chambr is provided in a drawer form and a basket 19 storing frozen foods is detachably provided at a rear surface of the door 13 for the freezing chamber
[31] In detail, both sides of a rear surface of the door 13 for the freezing chamber are provided with door frams extened backward, the side surfaces of the door frame and the freezing chamber 16 are connected by means of a rail member. Therefore, the door 13 for the freezing chamber is drwan out in a horizontal direction by means of the rail member.
[32] Also, the rear surface of the door 12 for the refrigerating chamber installed with the ice maker 20 is installed with an ice bank 12 storing ice. Therefore, ice made in the ice maker 20 is deiced so that it is dropped to the ice bank 12.
[33] Concretely, an upper surface of the ice bank 12 is opened and in the state where the door 12 for the refrigerating chamber is closed, an opening part of the ice bank 12 is positioned at a lower portion of the ice maker 20. And, ice can be made by directly supplying cooling air to the ice maker 20 or by providng a separate refrigerant pipe. In the present embodiment, the ice maker 20 can be configured of a structure having the separate refrigerant pipe. And, in the case of the sturcture where the refrigerant pipe is provided in the ice maker 20, it has an advantage in rapidly making ice when the ice maker 20 is exposed to the cooling air for the refrigerating chamber with a relatively high temperature. Therefore, in the refrigerator with the struture where the ice maker is provided in the refrigerating chamber, the ice maker provided with the refrigerant pipe may be advantageous. The structure and operation of the ice maker 20 provided with the refrigerant pipe will be described in detail below with reference to the ac- comanying drawings.
[34] On the other hand, in the case where the ice bank 12 is installed at the freezing chamber 15 or the door 12 for the refrigerating chamber, when considering characteristics of the refrigerating chamber 15 maintained at temperature above zero, a phenonmenon that ice sticks to each other due to the melting of ice can be caused.
[35] In order to solve such a problem, the inside of the ice bank 12 should be always maintained at sub-zero temperature to prevent the melting of ice.
[36] Hereinafter, a method for maintainting the inside of the ice bank 12 at a state where ice is not melted will be described in detail.
[37] Also, the refrigerator 10 further comprises a compressor 32 installed at a bottom surface of the freezing chamber 16 to compress a refrigerant, an evaporator 31 installed at a rear of the freezing chamber 16 to form cooing air, and a blowing fan 30 supplying the cooling air formed through the evaporator 31 to the refrigerating chamber 51 and the freezing chamber 16.
[38] Furthermore, the refrigerator comprises a freezing duct 17 supplying the cooling air ventilated from the blowing fan 30 to the freezing chamber 16 and a cooling duct 18 supplying the cooling air to the refrigerating chamber 15. The freezing duct 17 and the cooling duct 18 may be defined by the cooling air duct.
[39] In detail, the freezing duct 17 is provided with a plurality of cooling air holes for discharging the cooling air to the freezing chamber 16. Herein, the evaporator 31 and the blowing fan 30 are disposed in the inside of the freezing duct 17 as well as the evaporator 31 and the blowing fan 30 are disposed in a separate space of the main body 11. The freezing duct 17 connected to the freezing chamber 16 may be formed separately.
[40] Also, the cooling duct 18 is extended from a space accomodating the evaporator 31 and passes through the barrier 111 and then is connected to the refrigerating chamber 15. Herein, the cooling duct 18 may have a structure that it is directly communicated with the space accomodating the evaporator 31 as well as a structure that it is branched from the freezing duct 17.
[41] With the structure as above, the ice made in the ice maker 20 installed at the ceiling of the refrigerating chamber 15 is separated so that it is dropped to the ice bank 12. Hereion, a guide extended from the ice maker 20 or the ice bank 12 may be provided so that the ice separated from the ice maker 20 is safely dropped to the ice bank 12.
[42] Concretely, the ice bank 12 is provided with a container 211 in a cylinderical form whose upper portion is opened, an auger 212 provided at a lower side of the inside of the container to guide ice downward, a crusher 213 integrally connected to a lower end of the auger 212 to crush the ice, a motor 214 driving the crusher 213, and a shaft 215 connecting the motor 214 to the crusher 213 to transfer the rotatory power of the motor.
[43] Also, any one side of the ceiling portion of the refrigerating chamber 15 is provided with the ice maker 20. In detail, the ice maker 20 is disposed at the upper side of the ice bank 12 so that the discharged ice is directly dropped to the container 211 or it is configured to drop the ice to the container 211 by means of the guide after the ice is dropped.
[44] Meanwhile, the inside of the refrigerating chamber 15 is provided a plurality of shelves on which foods are safley seated. And, the cooling duct 18 is communicated with the space accomodating the evaporator 31, is raised along the wall surface of the refrigerating chamber 15, and is extended to the front of the refrigerating chamber 15 along the shelf 112.
[45] With the structure as above, at least a portion of the cooling air passing through the evaporator 31 to be cooled at low temperature is directly discharged to the container 211, thereby preventing the phenomenon that the ice received in the inside of the container 211 sticks to each other due to the melting of ice
[46] Also, the door 12 for the refrigerating chamber is provided as a side by side door as shown. The door 13 for the freezing chamber may be provided in a drawer form, but is not limited thereto. Likewise, the door 13 for the freezing chamber may be also provided as the side by side door.
[47] On the other hand, in addition to the structure that the cooling duct 18 extended to the container 211 of the ice bank 21 is extended along the bottom surface of the shelf 112 as shown, it may be extended along the upper or side surface of the shelf 112. In other words, the arrangement structure of the cooling duct 18 can be properly determined according to the installation position of the ice bank 21 provided to the door 12 for the refrigerating chamber. And, the cooling duct 18 is extended from the rear of the shelf end to the front end thereof, wherein its width may be equal to or smaller than a width of the cooling duct 18.
[48] For example, when the ice bank 21 is installed at an one side edge of the door 12 for the refrigerating chamber 12, the cooling duct 18 can be extended along the side surface of the shelf 112.
[49] Also, the end of the discharge side of the cooling duct 18 is formed to be inclined at a predetermined angle so that the cooling air can be discharged downward. This is to directly dicharge the cooling air to the inside of the container 211 of the ice banck 21. In other words, at least a portion of the cooling air passing through the evaporator 31 to be cooled at low temperature is directly discharged to the container 211, thereby preventing the phenomenon that the ice received in the inside of the container 211 sticks to due to the melting of ice.
[50] In addition, when the cooling air is discharged downward, an air curtain effect can be obtained by means of the discharged cooling air so that when the door for the re-
frigerating chamber is opened, an amount of the cooling air discharged to the outside can be reduced.
[51] FIG. 4 schematically shows a structure of a ice maker provided in a refrigerator according to an embodiment of the present invention.
[52] Referring to FIG. 4, the ice maker 20 provided in the refrigerator according to the embodiment of the present invention comprises a tray 201 storing water for making ice, a ice making pipe 40 extended to the inside of the tray 201, and a water supply apparatus for supplying water to the tray 201.
[53] In detail, the water supply apparatus comprises a water pail 42 storing water, a pump 41 pumping the water in the inside of the water pail 42, and a water pipe 43. And, a dispenser connecting pipe 44 can be branched from any one side of the water pipe 43 and a switching valve 45 is installed at the branch point to selectively control a flow direction of water. More specifically, the dispenser connecting pipe 44 is extended to the dispenser so tha a user can dispense portable water. And, a ratating axis 202 is extended to both sides of the tray 201. And, the water pail 42 may be buried in the inside of the body 11 or provided at one side of the wall surface of the refrigerating chamber.
[54] Further, the ice making pipe 40 is a pipe in which a portion of the refrigerant performing a refrigerant cycle flows. The pipe is curved and bent several times to form projecting parts 401 as shown. And, the projecting part 401 may be formed at a length that can be submerged in water supplied to the tray 201.
[55] Briefly describing the ice making process of the ice maker 20 forming such a structure, portable water for making ice is first supplied from an outside water pipe to the water pail 42. And, when the ice making process starts, the pump 41 is operated so that the water stored in the water pail 42 is supplied to the tray 201. And, when the water supplied to the tray 201 reaches a set water level, the supply of water stops and the refrigerant in low temperature and low pressure flows in the refrigerant pipe 40. The refrigerant pipe 40 is formed in a structure that a portion of the pipes configuring a freezing cycle is branched to be extended the tray 201. In order words, the refrigerant pipe may be formed in a structure that it is branched from any point of the pipe connected to an inlet side of the evaporator 31 to be extended to the tray 201. And, the refrigerant pipe 40 may be connected back to an outlet side of the compressor 32.
[56] On the other hand, in performing the ice making process, the ice making should be completed before the ice formed in the projection 401 contacts the ice formed at the neighboring projection 401. And, water remaining in the tray 201 is removed. Herein, as a method of removing the remain water, there may be a method of removing the remain water by a rotation of the tray 201 or a method of removing the remain water by a connection of a separate drain pump. And, if the remain water is completed, the
tray 201 is rotated at 180° and in this state, the ice from the refrigerant pipe 400 is deiced.
[57] In detail, as a method of deicing the ice from the refrigerant pipe 400, there may be a method of flwoing a high temperature of refrigerant in the refrigerant pipe 400 in the deicing process or a method of heating the refrigerant pipe 400 by attaching a heater to the surface of the refrigerant pipe 400.
[58] With the process as described above, the deiced ice is directly dropped to the ice bank 21 or dropped thereto by means of the guide. And, the ice dropped to the ice bank 21 is maintained at sub-zero temperature by means of the cooling air supplied from the cooling duct 18 or an auxiliary duct 28. In other words, the phenomenon that a lump of ice stored in the ice bank 21 sticks to each other due to the melting of ice is prevented.
[59] And, the ice maker 20 with the structure that the refrigerant pipe is extended to the inner space of the tray 201 can perform a rapid ice making even when it is directly exposed to the cooling air for the refrigerating chamber. Therefore, a separate heat insulating wall or heat insulating case structure for preventing the ice maker 20 from being exposed to the cooling air for the refrigerating chamber is not needed.
