Hereinafter, the structure, operation and function of the cooling device 10 will be described in more detail with reference to the drawings.

6 is a perspective view showing the cooling device. 7 is a perspective view of the cooling device viewed from above. 8 is a cut-away perspective view taken along line 8-8 'in FIG. 9 is a front view of the disassembled state of the cooling device.

6 to 9, the cooling device 10 according to the embodiment of the present invention may include a cooling unit and a cooling channel connected to the cooling unit.

In detail, the cooling unit includes a case 20 for forming a storage space for storing the beverage container 6, a cover 60 for opening and closing the inlet of the case 20, A fan motor assembly 30 mounted on the case 20 for forced cooling of the cool air and a fan motor assembly 30 coupled to the case 20 to receive the beverage container 6, And a drive assembly 40 for driving the motor 50.

More specifically, the case 20 is formed to open frontward and rearward, and a space in which the stirring member 50 and the beverage container 6 can be accommodated is formed therein. The driving assembly 40 may be provided on the rear side of the case 20 and the rear side of the case 20 may be shielded by the driving assembly 40.

The case 20 may include an upper case 201 and a lower case 202 coupled to the upper case 201. The upper case 201 forms an upper surface and right and left side surfaces of the case 201 and may be coupled to the lower case 202 to surround the lower case 202. The lower case 202 is mounted on the inner side of the upper case 201 and forms a rear surface, right and left side surfaces and a bottom surface of the case 20. A plurality of ribs are formed on the outer surface of the lower case 202 and a predetermined space is formed between the upper case 201 and the lower case 202 when the upper case 201 is coupled with the upper case 201. Accordingly, the wall surface of the case 20 has an air layer for heat insulation and a structure capable of preventing deformation due to impact. Of course, the heat insulating member may be interposed in the space between the upper case 201 and the lower case 202 to insulate the cooling device 10 from the refrigerating chamber 103.

An inlet 21 is formed on the front surface of the case 20 to allow the beverage container 6 to enter and exit. The inlet 21 is formed to protrude forward as it goes downward and is formed to have a downward inclination, and the beverage container 6 can be easily inserted in and out. The inlet 21 is opened and closed by a cover 60 having a corresponding shape. The cover 60 may be formed of a material at least partially transparent so as to form an outer shape of the front surface of the cooling device and to allow the inside of the case 20 to be seen through.

A gasket 61 may be provided around the cover 60 or at the front end of the case 20 to prevent leakage of cold air between the cover 60 and the case 20. The cover 60 may be fixed to the front end of the cover 60 or the case 20 so that the cover 60 is closed when the cover 60 is closed. Of course, since the inside of the case 20 becomes a negative pressure during operation, the cooling device 10 may maintain the closed state of the cover 60, so that there is no need for a separate fixing structure.

A cover engaging portion 212 is formed at the lower end of the inlet 21. The cover engaging portion 212 is axially engaged with the lower end of the cover 60. Accordingly, the cover 60 can rotate the cover engaging portion 212 to open and close the inlet 21.

A suction grill 23 may be provided on the lower surface of the case 20 so as to be detachably mounted on the bottom surface of the case 20 and positioned at an outlet end of the suction duct 11. The suction grille 23 is mounted on the cold air inlet 24 which is opened on the bottom surface of the case 20.

The cool air inlet 24 is formed at a predetermined position of the case 20. At this time, the position of the cool air inlet 24 may be formed at a position corresponding to a position where the beverage container 6 is seated when only one beverage container 6 is seated in the stirring member 50. Therefore, the cool air passing through the suction grille 23 is directed toward the outer surface of the beverage container 6 to cool the beverage container 6.

A plurality of air holes 231 may be formed on the bottom surface of the suction grille 23. In detail, a plurality of air holes 231 having a small diameter are formed on the bottom surface of the suction grille 23, so that the cool air passes through the inlet end of the suction duct 11, that is, the suction grille 23, It is rapidly accelerated. Therefore, a jet hole can be defined as a jet hole because the cool air can pass through the plurality of air holes 231 and form a jet flow. The cooling air holes 231 are arranged to have a predetermined spacing and are evenly distributed over the entire surface of the suction grille 23.

The air hole 231 allows the direction of the cool air discharged from the air hole 231 to be discharged in a direction intersecting a wide part of the beverage container 6 placed on the stirring member 50. That is, since the beverage container 6 such as a generally used bottle or can has the widest surface area of the side surface, the beverage container is seated on the stirring member 50 in a lying state, and the air hole 231 discharges Can be discharged toward the side of the beverage container (6). The cooling efficiency of the beverage container 6 is maximized when the cool air discharged from the air hole 231 contacts the beverage container 6 vertically.

The upper end of the suction grille 23 may be detachably attached to the bottom surface of the case 20 in a manner that the upper end of the suction grille 23 extends outwardly and is hooked on the bottom of the case 20. At this time, it is possible to provide a latching structure for preventing the suction grille 23 from being separated from the bottom surface of the case 20 by the sucked air.

The stirring member (50) is swingably installed in the case (20). In detail, the stirring member 50 is axially coupled to the stirring member support portion 25 formed on the inner rear surface of the case 20, and the other end is axially coupled to the supporter frame 26 at a forwardly spaced position .

In detail, the supporter frame 26 is disposed transversely (in the horizontal direction in Fig. 6) at the upper inner side of the case 20. The supporter frame 26 may be formed as a separate member and mounted inside the case 20 so that the guide supporter 54, which is one component of the stirring member 50, can be rotatably mounted.

The stirring member 50 is mounted on the inner side of the case 20 so as to be swingable in the left and right direction. The stirring member 50 is connected to the driving assembly 40 and continuously reciprocates left and right by a predetermined angle, The beverage inside the container 6 can be agitated. The detailed configuration of the stirring member 50 will be described later.

The cooling unit may further include a driving assembly 40 that provides a driving force so that the stirring member 50 can reciprocate in the right and left directions of the case 20 from inside the case 20 have.

The fan motor assembly 30 includes a suction fan 31 for forcedly flowing air, a fan housing 32 mounted on a rear surface of the case 20 to receive the suction fan 31, And a fan motor 33 mounted on the rear of the fan housing 32 to provide rotational force to the suction fan 31.

The fan motor 33 is located behind the case 20 and is disposed outside the case 20 so as to be connected to the suction fan 31. The fan motor 33 is accommodated in a fan motor housing 331 and the fan motor housing 331 is fixed to the fan housing 32 or the case 20 so that the fan motor 33 can be mounted do. The fan motor housing 331 may be configured to be supported by the partition wall 15.

In detail, the suction fan 31 is formed to have a structure capable of sucking cold air generated in the evaporation chamber 107 with strong suction force. When the suction fan 31 is used, the air flowing into the case 20 along the cool air passage moves at a high speed toward the rear side of the case 20 due to a strong suction force. During the movement, heat exchange occurs while contacting the outer peripheral surface of the beverage container (6) accommodated in the case (20). In the case where the suction fan 31 sucking air is used, the flow rate of air is remarkably faster than that in the case where a blower blowing air is used. This is because, when the suction fan 31 is used, the pressure difference between the front region and the rear region of the fan becomes larger in a short time. Since the flow rate of the air is increased, the flow rate of air flowing per unit time is increased, and as a result, the heat exchange amount between the beverage container 6 and the cool air is increased. Therefore, there is an advantage that the heat exchange efficiency is improved.

In addition, by using the suction fan 31, the cool air sucked by the fan exchanges heat with the beverage container 6 housed in the case 20 before passing through the fan motor 33 that drives the fan. Therefore, there is an advantage that the amount of heat exchange between the cool air and the beverage container 6 is relatively increased, and the heat exchange efficiency is improved. If the blower is used, the air sucked by the blower is heat-exchanged with the beverage container 6 after passing through the fan motor that drives the blower. That is, the cool air that is sucked passes through the fan motor, and firstly absorbs heat, and then exchanges heat with the beverage container 6. [ Therefore, in the case of using the suction fan 31, the heat exchange efficiency is improved as compared with the case of using the blower.

Further, the suction fan 31 may be a centrifugal fan that sucks air in the axial direction and discharges the air in the radial direction. The air passing through the case 20 flows horizontally as a whole, and a downward flow is required to return to the evaporation chamber 107. That is, the air flow direction when passing through the case 20 and the air flow direction after passing through the suction fan 31 cross each other. Therefore, in the case of a flow path in which the direction of flow crosses, a centrifugal fan is suitable.

Further, the suction fan 31 has an advantage that the flow resistance is less than that of the blower. For example, in the case of a blower that pushes out air, if there is a narrow gap or an obstacle on the movement path of the air, a phenomenon may occur in which the air does not pass through the gap or the obstacle and is spread or backward. On the other hand, in the case of the suction fan 31, air is sucked in at the inlet of the fan to generate a pressure difference. Therefore, the air in front of the clearance or the obstacle can easily pass through the clearance due to the pressure difference with the rear of the clearance, and can easily pass through the obstacle. As a result, there is an advantage that the air flow resistance is small and the flow rate is large when the suction fan 31 is used in comparison with the blower under the same condition.

In addition, the suction fan 31 according to the embodiment of the present invention is a kind of centrifugal fan, and differs in structure from the conventional centrifugal fan. In detail, the suction fan 31 includes a disk-shaped back plate 311, a blade 312 mounted on the front surface of the back plate 311, and a suction guide (not shown) 313). The blade 312 protrudes forward from the front surface of the back plate 311 with a predetermined width and extends in the form of a round with a predetermined curvature in the radial direction from the center of the back plate 311. Further, the suction guide 313 is characterized in that the functions of a conventional bell mouth and an orifice are performed in combination. That is to say, it is possible to smoothly guide the suction of the air into the suction fan 31 from the front of the fan housing 32 and to block the backward flow of the air radially discharged along the surface of the blade 312 .

Specifically, the suction guide 313 protrudes forward from the bottom of the circular shape, and protrudes in a shape in which the diameter gradually decreases. In other words, the longitudinal section of the suction guide 313 can be structured such that the cross-sectional diameter gradually decreases from the bottom portion to the upper end portion, and the cross-sectional diameter is kept constant at any point. As such, the outer circumferential surface of the suction guide 313 is smoothly rounded to minimize the flow resistance acting on the sucked air, thereby performing the function of the orifice. At the same time, a bell mouth function that minimizes the reverse flow of the air sucked through the inlet of the suction guide 313 can be performed by forming a tubular shape extending a predetermined length from the bottom of the suction guide 313 . Further, a grill 314 may be further provided in front of the suction guide 313 to prevent foreign objects from being sucked.

The cool air passage includes a suction duct 11 for supplying cool air generated in the evaporation chamber 107 to the case 20 and a return duct for discharging cool air in the case 20 to the freezer chamber 104. [ (12). In detail, the inlet (or inlet) of the suction duct 11 may communicate with the evaporation chamber 107, and the outlet (or outlet) may be connected to the bottom of the case 20. The inlet port of the return duct 12 is connected to the bottom surface of the fan housing 32 and the outlet port 121 communicates with the freezing chamber 104. That is, the cool air in the evaporator chamber 107 flows into the casing 20 by the suction duct 11, and the cool air passing through the casing 20 by the return duct 12 flows into the fan housing The refrigerant can be discharged to the inside of the freezing chamber 104 through the freezing chamber 32.

The rotation shaft 412 of the driving motor 41 extends to the inside of the case 20 and can be coupled with the power transmission unit 42 inside the case 20. [ The driving motor 41 may be provided inside the case 20 as necessary but may be provided outside the case 20 to prevent the cooling efficiency inside the cooling device 10 from being lowered due to heat generation .

A general DC motor can be used as the driving motor 41 and the rotational force of the driving motor 41 can be converted through the power transmitting unit 42 to swing the stirring member 50. The driving motor 41 may be a stepping motor capable of rotating forward and backward by a predetermined angle. Accordingly, the driving motor 41 is configured to be capable of repeating forward and reverse rotation at a predetermined angle, and can be configured to swing the stirring member 50.

On the other hand, the drive motor 41 is equipped with a power transmission unit 42. The power transmitting unit 42 includes a tilting member 421 connected to the rotating shaft 412 of the driving motor 41 and a connecting rod 422 connecting the tilting member 421 and the driving connecting unit 523 . At this time, the driving motor 41 is configured such that the rotating shaft 412 is disposed in parallel to the extending direction of the holder shaft 53.

More specifically, the tiltable member 421 is coupled to the rotation shaft 412 of the driving motor 41 and rotates together with the rotation shaft 412 when the rotation shaft 412 rotates. The pivoting member 421 includes a shaft coupling portion 421a extending in the same direction as the rotation shaft 412 and coupled with the rotation shaft 412 and a shaft portion 421a which is eccentric from the rotation center of the shaft coupling portion 421a And an extending portion 421b extending from the base end portion.

The inside of the shaft coupling portion 421a is recessed in a corresponding shape so that the power of the rotation shaft 412 can be transmitted, and the rotation shaft is inserted. Therefore, when the rotation shaft 412 rotates, the tiltable member 421 can rotate together.

The extension portion 421b extends from the front end of the shaft coupling portion 421a and extends at a position eccentric to the rotation center of the shaft coupling portion 421a. The extension portion 421b is rotatably coupled to the connection rod 422. [ Accordingly, when the shaft coupling portion 421a rotates, the extension portion 421b rotates the shaft coupling portion 421a with a predetermined locus about the rotation center, and the connection rod 422 is rotated by a predetermined displacement A linear reciprocating motion becomes possible.

Meanwhile, the connection rod 422 may be formed in a rod shape having a predetermined length, which is disposed in a direction intersecting the extension direction of the rotation shaft 412 and the holder shaft 53. At both ends of the connection rod 422, a coupling hole 422a is formed which can be coupled to the shaft. The coupling portion 422a of the connection rod 422 is rotatably coupled to the extension portion 421b and the other end of the connection rod 422 is rotatably coupled to the driving connection portion 523 by a rotation shaft 424. [

In detail, when the driving motor 41 rotates, the rotating member 421 rotates together with the rotating shaft 412 of the driving motor 41. 15, when the extension portion 421b of the pivoting member 421 is positioned on the left side, the connection rod 422 pulls the drive connection portion 523 to the left. Since the driving connection portion 523 is located below the rotation axis of the rear supporter 52, when the connection rod 422 pulls the driving connection portion 523 to the left, the stirring member 50 is rotated about the rotation axis It rotates clockwise and tilts to the left.

16, when the extension portion 421b of the pivoting member 421 is positioned on the right side, the connection rod 422 pushes the driving connection portion 523 in the right direction. Therefore, the stirring member 50 is rotated counterclockwise about the rotation axis 522 and tilted to the left.

Thus, the rotational force of the driving motor 41 is transmitted to the stirring member 50 by the power transmitting unit 42. Therefore, when the driving motor 41 is continuously rotated, the stirring member 50 rotates clockwise and counterclockwise repeatedly within a set angle range, and as a result, the stirring member 50 is reciprocatingly swinging left and right . The beverage in the beverage container 6 placed on the stirring member 50 is agitated by the repetitive swing motion of the stirring member 50, so that the cooling rate of the beverage can be increased faster.

In this state, the cover (60) completely shields the inlet (21) of the case (20).

That is, the user can close the cover 60 only by closing the door 3 of the refrigerator without closing the cover 60 in a state where the cover 60 is opened, The problem of the cover 60 being damaged or the like can be solved. Also, the cover 60 can be closed only by the operation of the door 3, so that convenience in use can be improved.

The rear surface of the door 3 may be a door liner or a door dike forming the overall shape of the rear surface of the door 3 or may be a separate receiving member mounted on the door 3, Or may be another structure provided on the substrate 3.

Meanwhile, when the cover 60 is closed, the gasket 61 mounted on the cover 60 is brought into contact with the periphery of the inlet 21 of the case 20 to prevent leakage of cold air. When the cooling device 10 is driven in a state where the cover 60 is closed, a negative pressure is applied to the interior of the case 20 by the suction fan 31, So that it is possible to prevent leakage of cold air during operation of the cooling device 10. [

Hereinafter, an operation of the refrigerator having the above-described configuration will be described with reference to the drawings.

23 is a block diagram schematically showing a control flow of the refrigerator. 24 is a flowchart showing a control method of the refrigerator.

Referring to FIGS. 23 and 24, cold air can be generated in the evaporator 108 due to the driving of the refrigeration cycle of the refrigerator, and the generated cold air is circulated through the refrigerating compartment fan 81 and the freezing compartment fan 82, The normal operation is performed such that the refrigerant is supplied to the freezing chamber 103 and the freezing chamber 104 to cool the refrigerating chamber 103 and the freezing chamber 104 to maintain the set temperature.

In this state, in order to rapidly cool the beverage contained in the beverage container 6 and the beverage container 6, the user opens the refrigerator compartment door 2 and opens the cover 60 of the cooling device 10 So that the beverage container 6 is housed. At this time, the beverage container 6 is positioned at an appropriate position according to the number of the beverage containers 6 in a state of being seated on the stirring member 50.

In a state where the beverage container 6 is seated, the user closes the cover 60 and closes the refrigerator compartment door 2 in order. At this time, the cover (60) is configured to be interlocked with the refrigerator compartment door (2), and when the refrigerator compartment door (2) is closed, the cover (60) can be closed. The inside of the cooling device 10 can be sealed when the cover 60 is closed and cool air inside the cooling device 10 is not discharged to the outside during operation of the cooling device 10. [ In this state, the cooling apparatus 10 completes preparation for driving, and operation is started by the user's operation.

The user operates the display unit 5 to drive the cooling device 10. [ At this time, the display unit 5 displays the operation state of the cooling device 10, as well as the operation of the cooling device 10.

At this time, the user can set the operation time of the cooling device 10 according to the number or type of beverage stored in the cooling device 10. [ That is, the cooling device 10 can be operated in at least two operation modes, and the user can be configured to select it through the display unit 5. For example, the cooling device can be operated for 4 minutes or 8 minutes, and the user can set the operation time in the display unit 5 to cool the beverage container 6 according to the type of the beverage to be cooled.

Of course, if a sensor or a device capable of measuring the temperature of the beverage container is provided in the cooling device 10, the cooling device 10 is operated until the beverage container 6 reaches a desired temperature It may be set to be driven.

The cooling unit 10 starts driving by the control unit 7 at the same time as the operation setting of the cooling unit 10 or the input of the operation signal through the display unit 5 and the cooling unit 10 The rapid cooling of the beverage container 6 housed inside the beverage container 6 is performed.

In order to more effectively cool the cooling device 10, the cooling device 10 starts to be driven, and at the same time, the compressor 83 constituting the refrigeration cycle is rotated at the maximum output, The refrigerator compartment fan 81 that supplies cold air stops operating. Then, the freezer compartment fan 82, which supplies the cool air to the freezer compartment 104, stops its operation or rotates at a low speed. In this state, the cool air generated in the evaporator 108 can be supplied to the cooling device 10 to maximize the cooling performance of the cooling device 10.

When the evaporator 108 includes a freezer compartment evaporator 108 for cooling the freezer compartment 104 and a refrigerating compartment evaporator 108 for cooling the refrigerating compartment 103, The evaporator 108 and the freezer compartment evaporator 108 are connected to each other to switch the valve 84 to supply the refrigerant to the freezer compartment evaporator 108 when the freezer compartment evaporator 108 is driven, The amount of the coolant supplied to the cooler 108 is maximized, so that the cooler 10 can be effectively cooled.

On the other hand, when the operation signal of the cooling device 10 is inputted, the damper 122 is opened. Then, the fan motor 33 and the drive motor 41 start driving at the same time. The suction fan 31 connected to the fan motor 33 is rotated by the operation of the fan motor 33. By the rotation of the suction fan 31, the cool air of the evaporator 108 flows into the suction duct 11, and can be guided to the inside of the case 20 by the suction grille 23.

In detail, a discharge end of the suction duct 11 is connected to a bottom surface of the case 20. The suction grille 23 is positioned at a position where the discharge end of the suction duct 11 is connected and the air sucked through the suction duct 11 passes through the suction grille 23, do. This is accomplished by the air hole 231 formed in the suction grille 23 as described above.

The high-speed cool air passing through the suction grille 23 is discharged in a direction perpendicular to the outer peripheral surface of the beverage container 6. [ Since most of the beverage containers 6 are formed in a cylindrical shape, the heat exchange efficiency is best when the cool air passing through the suction grille 23 strikes the outer peripheral surface of the beverage container 6 vertically. If the flow direction of the cold air passing through the suction grille 23 and the outer peripheral surface of the beverage container 6 are not orthogonal to each other, a part of the cool air does not hit the outer peripheral surface of the beverage container 6, And can be discharged to the outside. That is, in order to minimize the amount of cool air immediately discharged to the outside without a heat exchange action, it is preferable that the cool air sucked through the suction grille 23 hits the outer peripheral surface of the beverage container 6 vertically.

The cool air flowing through the suction grille 23 is moved along the outer circumferential surface of the beverage container 6 by the air guide 55 so that the amount of cool air in contact with the beverage container 6 is maximized So that the beverage container 6 can be cooled more quickly.

Meanwhile, the chilled air sucked in the axial direction of the suction fan 31 is discharged in the radial direction of the suction fan 31, and guided by the fan housing 32 to be guided through the return duct 12 to the freezing chamber 104 ). At this time, the damper 122 can be discharged to the freezing chamber 104 through the return duct 12, which has been opened and exchanged heat.

The swing motion of the stirring member (50) is performed simultaneously with the rotation of the suction fan (31). To this end, the drive motor 41 is driven. The driving motor 41 can continuously or regularly rotate at a predetermined angle and the stirring member 50 can be rotated by the action of the power transmitting unit 42 connected to the rotating shaft 412 of the driving motor 41. [ Thereby making it possible to repeatedly swing.

When the stirring member 50 swings at the same time as the suction fan 31 sucks the cool air, the liquid inside the beverage container 6 can be quickly cooled while being stirred. Particularly, the cool air passing through the suction grille 23 by the air guide 55 can effectively cool the surface of the beverage container 6, so that the beverage inside the beverage container 6 can be cooled more quickly, The cooling can be effectively performed.

On the other hand, the cooling device 10 can accumulate the time operated by the timer 85 and stop after the cooling device 10 is operated for the set time T1. When the stop signal of the cooling device 10 is transmitted, the damper 122 is closed to cover the return duct 12, and the fan motor 33 and the driving motor 41 stop driving do. Therefore, the circulation of the cool air between the evaporation chamber 107 and the cooling device 10 and the freezing chamber 104 is stopped.

When the fan motor 33 and the driving motor 41 are stopped and the cooling of the cooling device 10 is completed, the timer 85 is initialized for re-operation of the cooling device 10 The timer 85 re-integrates the driving time of the cooling device 10 when the cooling device 10 is restarted.

When the operation of the cooling device 10 is completed, the display unit 5 indicates that the operation of the cooling device 10 is completed. Also, if a separate output member 86 such as a speaker is additionally provided, it is possible to inform the user that the operation of the cooling apparatus 10 has been completed by voice or otherwise.

The refrigerator compartment fan 81 and the freezer compartment fan 82 are operated to cool the freezer compartment 104 and the refrigerating compartment 103 to a predetermined temperature in a normal operation state after the operation of the cooling device 10 is completed, The valve 84 is also opened and closed so that the freezing chamber 104 and the refrigerating chamber 103 can maintain a predetermined temperature.

On the other hand, the cooling device 10 maintains the above-described operation state in a normal operation state. However, when the refrigerator compartment door 2 is opened, the defrosting operation state, the overload state, or the initial operation state after the refrigerator installation or power failure, It is possible to stop the operation of the cooling device 10 when the operation is to be stopped.

In order to determine whether the cooling device 10 for forced operation is stopped, the controller may include a door switch 87 for detecting opening and closing of the refrigerator compartment door 2, a defrost sensor 88 for detecting a defrosting operation, A timer 85 or a counter for detecting the overload of the cooling device 10 may be connected to the controller 7. [

Hereinafter, the algorithm of the forced stop operation will be described in detail with reference to the drawings.

25 is a flowchart showing a forced operation stopping algorithm of the cooling device when the refrigerator door is opened.

25, in order to stop the driving of the cooling device 10 while the cooling device 10 is being driven, a user inputs the stop signal by operating the display unit 5, (2) is opened to stop the driving of the cooling device (10).

In detail, when the operation for stopping the driving of the cooling device 10 is performed through the display unit 5, the cooling device 10 stops driving. When the refrigerator compartment door 2 is opened after the operation of the display unit 5, the opening of the refrigerator compartment door 2 is sensed by the door switch 87 immediately after opening the refrigerator compartment door 2, The damper 122 is closed and the operation of the cooling device 10 is stopped. When the cooling device 10 is stopped, the timer 85 stops the accumulation of the cooling device driving time. Then, the door open state is output through the display unit 5 or the output member 86.

In this state, the driving of the cooling device 10 is stopped, and the user can take out the beverage container 6 inside the cooling device 10 or store the food in the refrigerator.

On the other hand, when the opened refrigerator compartment door 2 is closed, the door switch 87 detects the closing of the refrigerator compartment door 2 and transfers the sensed result to the controller 7. When the refrigerator compartment door 2 is closed, the timer 85 accumulates the closing time of the refrigerator compartment door 2, and the closing time of the refrigerator compartment door 2 becomes longer than the set time T2 , It is possible to terminate the operation of the cooling device 10 since the driving time of the cooling device 10 has reached the set time T1. On the other hand, if the user again operates the display unit 5 to input the re-operation of the cooling device 10 in a state where the closed time of the refrigerator compartment door 2 has not reached the set time T2, The damper 122 is opened and the operation of the cooling device 10 is restarted. At this time, the timer 85 accumulates the operation time of the stopped cooling device 10, and the cooling device 10 is driven for the remaining time.

On the other hand, when the refrigerator compartment door 2 is opened immediately after the display unit 5 is not operated, the damper 122 is closed and the refrigerator 10 is stopped immediately. The timer 85 can terminate the operation of the cooling device 10 because the driving time of the cooling device 10 has reached the set time T1.

That is, when the refrigerator compartment door 2 is opened without closing the cooling device 10 and then closed again, the cooling device 10 immediately ends the operation and then returns to the normal operation. When the operation of the cooling device 10 is operated again after the refrigerator compartment door 2 is opened and closed in order after stopping the cooling device 10, So that the driving of the cooling device can be completed.

26 is a flowchart showing a forced operation stopping algorithm of the cooling device during the defrosting operation of the refrigerator.

26, when the defrost heater 89 is operated or the defrosting operation by the defrosting sensor 88 is detected during the operation of the cooling device 10 and a defrost signal is inputted, After completion of driving, the defrosting operation is performed.

More specifically, when the cooling device 10 is being driven while the defrost signal is being input, the start of the defrosting operation is suspended and the drive time of the cooling device 10 The cooling device 10 is driven while being continuously accumulated. After the driving time of the cooling device 10 is set for the set time T1, the damper 122 is closed and the cooling device 10 is stopped. Then, the display unit 5 outputs that the operation of the cooling device 10 is completed.

Thus, when the operation of the cooling device 10 is completed, the defrosting operation is performed. While the defrosting operation is being started, the defrosting operation time is accumulated in the timer 85. When the time accumulated in the timer 85 or the set time T3 after completion of the defrosting operation, for example, 30 minutes The forced stop operation is terminated.

That is, when the defrosting operation signal is inputted during the operation of the cooling device 10, the operation of the cooling device 10 in progress is completed and the defrosting operation is performed. At this time, the cooling device 10 becomes operable again after the defrosting operation time or the set time T3 after the defrost operation has elapsed.

FIG. 27 is a flowchart showing a forced operation stopping algorithm of the cooling device when the cooling device is overloaded. FIG.

Referring to FIG. 27, the cooling device 10 can be continuously operated after the operation is completed. If the cooling device 10 is operated a plurality of times in succession, the fan motor of the cooling device 10 may be overloaded. At this time, the overload of the cooling device 10 can be determined on the basis of the time or the number of times the cooling device 10 is operated within a predetermined time. For example, if the cooling device 10 is operated for 25 minutes or more for 30 minutes or the cooling device 10 is operated 5 times or more for 30 minutes, the control unit 7 determines whether the cooling device 10 is overloaded .

When the cooling device 10 is being driven when an overload is detected during operation of the cooling device 10, the drive time of the cooling device 10 accumulated in the timer 85 reaches the set time T1 The cooling device 10 is driven. After the cooling device 10 is driven for the set time T1, the damper 122 is closed and the cooling device 10 is stopped. Then, the completion of the operation of the cooling device 10 is output through the output member 86.

When the overheating of the cooling device 10 is detected, the cooling device 10 has a forced stop period for 30 minutes, for example, a set time T4. Until the set time T4 is reached, The re-operation of the battery 10 is not performed. When the forced stop period of the cooling device 10 has passed, the cooling device 10 can be operated again after the forced stopping operation is completed.

28 is a flowchart showing a forced operation stopping algorithm of the cooling device during an initial operation of the refrigerator.

In Fig. 28, the cooling device 10 is not operated during the initial operation of the refrigerator, and is operated after the initial operation of the refrigerator is completed.

In detail, when the refrigerator is moved or the power of the refrigerator is turned off again, the damper 122 is closed and the cooling device 10 is also stopped. During the initial operation, the initial operation state is output through the output means.

When the initial operation is completed (for example, when the refrigerant in the refrigeration cycle completely circulates through one cycle), the damper 122 is opened and the cooling device 10 starts to be driven. When the driving of the cooling device 10 is temporarily stopped by the initial operation, the driving of the cooling device 10 can be restarted after completion of the initial operation.

When the forced shutdown operation is completed, the refrigerator can be returned to the normal operation again, and the cooling device 10 can be driven again according to the user's operation.
