Fig. 1 is a sectional view illustrating an example of a refrigerator according to an embodiment of the present disclosure. The refrigerator may have a storage chamber W in which goods and the like may be stored. The refrigerator may include acabinet 1 in which a storage chamber W is formed. The refrigerator may further include adoor 50 that opens and closes the storage chamber W. Thedoor 50 may include at least one of a rotatable door 5 (e.g., a swinging door) or an advancing and retracting type door 6 (e.g., a drawer). Thecabinet 1 may include anouter case 7 forming an outer appearance and aninner case 8 forming at least one surface for forming the storage chamber W therein. - The storage chamber W may be a storage chamber to receive mainly certain kinds of goods which are preferably stored at a specific temperature range. For example, the storage chamber W may be a dedicated storage chamber for storing certain goods that need to be kept warm or cold, for example, alcoholic liquors such as wine and beer, fermented foods, cosmetics, or medical supplies. As one example, the storage chamber for receiving wine may be maintained at a temperature range of 3°C to 20°C, and this temperature range is relatively higher than temperatures for the refrigerating chamber of a conventional refrigerator to receive food items, and is preferable not to exceed 20°C. More specifically, the temperature of the storage chamber for red wine can be adjusted to 12°C to 18°C, and the temperature of the storage chamber for white wine can be adjusted to 6°C to 11°C. In another example, the temperature of the storage chamber for champagne can be adjusted to about 5°C.
- The temperature of the storage chamber W can be adjusted such that the storage chamber temperature fluctuates between a target temperature upper limit value and a target temperature lower limit value of the storage chamber W. The quality or freshness of the goods stored in the storage chamber W may be reduced by the difference between the target temperature upper limit value and the target temperature lower limit value (hereinafter, referred to as storage chamber temperature difference). The refrigerator may be manufactured with a small storage chamber temperature difference according to the type of the goods and may minimize the reduction of the quality of the goods. The storage chamber W of the refrigerator of the present embodiment may be a storage chamber having a smaller storage chamber temperature difference than that of a general refrigerator. For example, the storage chamber temperature difference of the storage chamber W may be less than 3°C and may be 2°C, as an example. Of course, in a case of considering certain types of goods that are very sensitive to temperature changes, the storage chamber temperature difference may be less than 1°C.
- The refrigerator may include a device capable of adjusting the temperature of the storage chamber W (hereinafter, referred to as a "temperature adjusting device" or "temperature adjusting module"). The temperature adjusting device may include at least one of a cooling device or a heating device. The temperature adjusting device may cool or heat the storage chamber W by at least one of conduction, convection, and radiation. For example, a cooling device (or heat exchanger), such as an
evaporator 150 or a heat absorbing body of a thermoelectric element, may be attached to theinner case 8 to cool the storage chamber W by conduction. By adding an airflow forming mechanism such as a fan, the air may be heat-exchanged with the cooling device by convection and supplied to the storage chamber W. In another example, a heating device, such as a heater or a heat generating body of the thermoelectric element, may be attached to theinner case 8 to heat the storage chamber W by conduction. An airflow forming mechanism, such as a fan, can supply a flow of air that is heated by convection and provided to the storage chamber W by convection. - In the present specification, the cooling device may be defined as a device capable of cooling the storage chamber W, including at least one of the
evaporator 150, the heat absorbing body of the thermoelectric element, or the fan. In addition, the heating device may be defined as a device capable of heating the storage chamber W, including at least one of a heater, a heat generating body of the thermoelectric element, or a fan. - The refrigerator may further include an inner guide or wall (or flow path housing) 200. The
inner guide 200 may partition an inner portion of theinner case 8 into a first space in which goods are stored and a second space in which a temperature adjusting device is located (the second space hereinafter being referred to as a "temperature adjusting device chamber"). The temperature adjusting device chamber may include a cooling device chamber and a heating device chamber. For example, the temperature adjusting device chamber can be located between theinner guide 200 and theinner case 8, between theinner guide 200 and theouter case 7, or inside theinner guide 200, such as in the storage chamber W. - The
inner guide 200 may be disposed to partition a cold air flow path P for supplying cold air to the space where goods are stored and the storage chamber W, and at least one cooling device may be disposed in the cold air flow path P. Theinner guide 200 may be further disposed to partition a space in which goods are stored and a hot air flow path P for supplying heat to the storage chamber W, and at least one heating device may be disposed in the hot air flow path P. The inner guide for the cooling device and the inner guide for the heating device may be designed in common or may be manufactured separately. Theinner guide 200 may form a storage space together with theinner case 8. Theinner guide 200 may be disposed in front of the rear body of the inner case. - The refrigerator may have one space having the same storage chamber temperature range of the storage chamber W or may have two or more spaces having different storage temperature ranges from each other (such as freezer/refrigerator combination. The refrigerator may further include a
partition member 3 disposed vertically or horizontally in order to divide the storage chambers W into two or more spaces (for example, a first space W1 and a second space W2) which have different storage chamber temperatures range from each other. - The refrigerator may further include the
partition member 10 disposed vertically or horizontally in order to divide the storage chambers W into two or more spaces (for example, a second space W2, a third space W3) which have different storage chamber temperatures range from each other. Thepartition member 10 may be separately manufactured and then mounted in theinner case 8. Thepartition member 10 may be manufactured as a heat insulating material disposed between theouter case 7 and theinner cases 8 and 9. - The two or more spaces may be different in size and locations. For example, the first space W1 may be located at the upper side, the second space W2 may be located at the lower side, and the
partition member 3 may be disposed so that the size of the first space W1 is larger than the size of the second space W2. In one example, the first storage chamber temperature for the first space W may be higher than the second storage chamber temperature for the second space W2. - In the present specification, it can be defined that a meaning of the first storage chamber temperature being higher than the second storage chamber temperature corresponds to at least one case of a case where the maximum value of the first storage chamber temperature is greater than the maximum value of the second storage chamber temperature, a case where the average value of the first storage chamber temperature is greater than the average value of the second storage chamber temperature, a case where the minimum value of the first storage chamber temperature is greater than the minimum value of the second storage chamber temperature, or a case where a current detected value of the first storage chamber temperature is greater than a current detected value of the second storage chamber temperature..
- The refrigerator may further include a door (hereinafter, a see-through door) through which the user can see the storage chamber through a see-through window without opening the
door 50 from the outside of the refrigerator, and the see-through door will be described later. In addition, the refrigerator may further include atransparent gasket 24 disposed on at least one of the see-through door or thepartition members transparent gasket 24 may combine with thepartition members - The refrigerator may further include door opening modules (or door motors) 11 and 11' for guiding an opening motion of the
door 50. Thedoor opening modules 11 and 11' may be a rotatabledoor opening module 11 which can allow thedoor 5 to be rotated more than a predetermined angle without the user holding thedoor 5, or an advancing and retracting type door opening module 11' which can allow the door (e.g., a drawer) 6 to be advanced and retracted in a front and rear direction. Thedoor opening modules 11 and 11' will be described later. - The refrigerator may further include a lifting module (or lifting mechanism) 13 capable of lifting or lowering the holder (or bin) 12, and although not illustrated in
Fig. 1 , the lifting module may be located in at least one of the storage chamber or the door. - As previously described, the refrigerator may include a plurality of doors for opening and closing two or more spaces having different storage temperature ranges from each other. At least one of the plurality of doors may be a see-through door having a region that is formed of a transparent or translucent material, such as glass. At least one of the
cabinet 1 or the plurality of doors may includedoor opening modules 11 and 11'. Thelifting module 13 for lifting and lowering the holder located in the storage chamber to open and close may be disposed on at least one of the plurality of doors. For example, the door for the storage chamber located at the top may be a see-through door, and alifting module 13 for lifting and lowering aholder 12 of a storage chamber located at the lower portion may be disposed. -
Fig. 2 is a sectional view illustrating an example of another type of refrigerator according to an embodiment of the present disclosure. Hereinafter, the storage chamber W illustrated inFig. 1 will be described as a first storage chamber W. The refrigerator may further include at least one of the first storage chamber W (e.g., first chambers W1 and W2) and at least one second storage chamber C that may be temperature-controlled independently of the first storage chamber W. Hereinafter, a detailed description of the same configuration and operation as those of the storage chamber W illustrated inFig. 1 will be omitted for the first storage chamber W, and a different configuration and operation from the storage chamber W illustrated inFig. 1 will be described. - The second storage chamber C may be a storage chamber having a temperature range lower than the temperature range of the first storage chamber W and, for example, may be a storage chamber having a temperature range of -24°C to 7°C. The second storage chamber C may be a storage chamber which is temperature-controlled based on a target temperature, which is a temperature selected by a user in this lower temperature range (e.g., between -24°C to 7°C). The second storage chamber C may be composed of a switching chamber (or a temperature changing chamber) in which any one of a plurality of temperature ranges may be selected, or may be configured as a non-switching chamber having one temperature range.
- The switching chamber is a storage chamber which can be temperature-controlled to a selected temperature range among a plurality of temperature ranges, and the plurality of temperature ranges may include, for example, a first temperature range above zero, a second temperature range below zero, and a third temperature range between the first temperature range and the second temperature range. For example, the user may provide an input to control the second storage chamber C to operate in a mode (for example, a refrigerating chamber mode) associated with a temperature range above zero, and accordingly, the temperature range of the second storage chamber C may be selected a temperature range above zero (for example, 1°C to 7°C). For example, the user may further input a desired temperature in the temperature range above zero, and the target temperature of the second storage chamber C may be a specific temperature (for example, 4°C) entered by a user in the temperature range (for example, 1°C to 7°C) above zero.
- In another example, the user can provide an input to select an operating mode in which the second storage chamber C is maintained in the temperature range below zero (for example, freezing chamber mode) or a special mode (for example, a mode for maintaining an optimal temperature range for storing certain kind of goods, such as a kimchi storage mode). For example, the user may further input a desired temperature in the temperature range below zero or a desired temperature for the certain type of goods, and the second storage chamber C may be maintained within a temperature range that is centered at or otherwise includes the specific inputted temperature.
- As previously described, the first storage chamber W may be a specific goods storage chamber in a specific temperature range or other environmental conditions (e.g., humidity, light levels, etc.) are maintained to optimally store a particular kind of goods or to mainly store a certain kind of goods, or the second storage chamber C may be a non-specific goods storage chamber in which a various kinds of goods may be stored in addition to a specific kind of goods. Examples of specific goods may include alcoholic beverages such as wine, fermented foods, cosmetics, and medical supplies. For example, the first storage chamber W may be a storage chamber in which wine is stored or a wine chamber in which wine is mainly stored, and the second storage chamber C may be a non-wine chamber in which goods other than wine are stored or goods other than wine are mainly stored.
- A storage chamber having a relatively small storage chamber temperature difference among the first storage chamber W and the second storage chamber C may be defined as a constant temperature chamber, and a storage chamber having a relatively large storage chamber temperature difference among the first storage chamber W and the second storage chamber C may be defined as a non-constant temperature chamber.
- Any one of the first storage chamber W and the second storage chamber C may be a priority storage chamber which is controlled in priority, and the other may be a subordinate storage chamber which is controlled in relatively subordinate. A first goods having a large or expensive quality change according to the temperature change may be stored in the priority storage chamber, and A second goods having a small or low quality change according to the temperature change may be stored in the subordinate storage chamber.
- The refrigerator may perform a specific operation for the priority storage chamber and a specific operation for the subordinate storage chamber. The specific operation includes a general operation and a special operation for the storage chamber. A general operation may include, for example, a conventional cooling operation for the storage chamber cooling. The special operation may include, for example, a defrost operation for defrosting the cooling device, a door load response operation that can be performed when one or more predetermined conditions are satisfied after the door is opened, or an initial power supply operation, which is an operation when the power is first supplied to the refrigerator.
- The refrigerator may be controlled such that a specific operation for the priority storage chamber is performed first when two operations collide with each other. Here, the collision of the two operations may be occur, for example, as a case where the start condition of the first operation and the start condition of the second operation are satisfied at the same time; as a case where the start condition of the first operation is satisfied and thus the start condition of the second operation is satisfied while the first operation is in progress; or as a case where the start condition of the second operation is satisfied and thus the start condition of the first operation is satisfied while the second operation is in progress.
- For example, in the refrigerator, the priority storage chamber may be cooled or heated prior to the subordinate storage chamber when the temperature of the priority storage chamber is not satisfied, and the temperature of the subordinate storage chamber is not satisfied. In another example, while the cooling device for cooling the subordinate storage chamber is being defrosted, if the temperature of the priority storage chamber is not satisfied, the priority storage chamber may be cooled or heated while the cooling device of the subordinate storage chamber is being defrosted (even if this cooling or heating of the priority chamber may interfere with defrosting the cooling device of the subordinate storage chamber).
- In another example, if the temperature of the priority storage chamber is not satisfied (e.g., outside of a desired temperature range) while the subordinate storage chamber is in progress of the door load response operation, the priority storage chamber may be cooled or heated during the door load response operation of the subordinate storage chamber such that the temperature of the priority storage chamber may be adjusted to be within the desired temperature range.
- In certain configurations, any one of the first storage chamber W or the second storage chamber C may be a storage chamber in which the temperature is adjusted by the first cooling device and the heating device, and the other is a storage chamber in which the temperature is adjusted by a second cooling mechanism or device.
- In the refrigerator, a separate receiving member (or storage drawer) 4 may be additionally disposed in at least one of the first space W1 or the second space W2. In the receiving
member 4, a separate space S (hereinafter, referred to as a receiving space) may be formed separately from the first space W1 and the second space W2 to accommodate goods. The refrigerator may adjust the receiving space S of the receivingmember 4 to a temperature range different from that of the first space W1 and the second space W2. - The receiving
member 4 may be disposed to be located in the second space W2 provided below the first space W1. The receiving space S of the receivingmember 4 may be smaller than the second space W2. In one example, the storage chamber temperature of the receiving space S may be equal to or less than the storage chamber temperature of the second space W2. - In the refrigerator, in order to dispose as
many shelves 2 as possible in the first storage chamber W, the length of the refrigerator itself in the vertical direction may be longer than the width in the horizontal direction, and in this case, the length of the refrigerator in the vertical direction may be more than twice the width in the horizontal direction. Meanwhile, since the refrigerator may be unstable and tip over if the length in the vertical direction is too long relative to the width in the horizontal direction, it may be preferable that the length in the vertical direction is less than three times the width in the horizontal direction. Certain examples of the length in the vertical direction that can store a plurality of the specific goods may be 2.3 to 3 times the width in a left and right direction, and a particular example may be 2.4 to 3 times the width in the left and right direction. - Meanwhile, even if the length of the refrigerator in the vertical direction is longer than the width in the left and right direction, when the length of the storage chamber in which the specific goods are substantially stored (for example, the first storage chamber W) is relatively short in a vertical direction, the number of specific goods that may be received in the storage chamber may not be high. In the refrigerator, preferably, the length of the first storage chamber W in the vertical direction is longer than the length of the second storage chamber C in the vertical direction so that the specific goods can be stored as much as possible. For example, the length of the first storage chamber W in the vertical direction may be 1.1 times to 1.5 times the length of the second storage chamber C in the vertical direction.
- At least one of the
first door 5 and thesecond door 6 may be a see-through door, and aspects of the see-through door will be described later. The refrigerator may further includedoor opening modules 11 and 11' for providing a force for automatically opening at least one of thefirst door 5 or thesecond door 6 coupled to thedoor opening modules 11 and 11', and thedoor opening modules 11 and 11' will be described later. In at least one of the first storage chamber W, the second storage chamber C, and thefirst door 5, or thesecond door 6, alifting module 13 capable of lifting theholder 12 may be disposed. Thelifting module 13 will be described later. -
Fig. 3 is a front view when a refrigerator according to an embodiment of the present disclosure is positioned adjacent to another refrigerator. The refrigerator described in the present disclosure may be disposed adjacent to one or more other refrigerators, and a pair of adjacent refrigerators may be disposed, for example, in the left and right direction. Hereinafter, for convenience of description, the first refrigerator Q1 and the second refrigerator Q2 will be referred for description thereof, and the same configuration of the first refrigerator Q1 and the second refrigerator Q2 as each other will be described using the same reference numerals for convenience of description. In one example, a refrigerator may include a plurality of storage chambers that may be located in the left and right direction and the vertical direction in one outer case, such as a side by side type refrigerator or a French door type refrigerator. - At least one of the first refrigerator Q1 or the second refrigerator Q2 may be a refrigerator to which an embodiment of the present disclosure is applied. Although the first refrigerator Q1 and the second refrigerator Q2 may have some functions that different from each other, the lengths (or heights) of the first and second refrigerators Q1 and Q2 in the vertical direction be the same or almost similar so that the overall appearance may give the same or similar feeling when disposed adjacent to each other in the left and right direction.
- Each of the first refrigerator Q1 and the second refrigerator Q2 may include each of a first storage chamber and a second storage chamber, and the first storage chamber and the second storage chamber may include a
partition member 10 partitioning in the vertical direction, respectively, and thepartition member 10 of the first refrigerator Q1 and thepartition member 10 of the second refrigerator Q2 may overlap in the horizontal direction. - The
upper end 6A of thesecond door 6 opening and closing the second storage chamber of the first refrigerator Q1 and theupper end 6A of thesecond door 6 opening and closing the second storage chamber of the second refrigerator Q2 can coincide with each other in the horizontal direction. Similarly, thelower end 6B of thesecond door 6 opening and closing the second storage chamber of the first refrigerator Q1 and thelower end 6B of thesecond door 6 opening and closing the second storage chamber of the second refrigerator Q2 can coincide with each other in the horizontal direction. -
Fig. 4 is a view illustrating on and off of a cooling device and on and off of heating device according to the temperature change of the storage chamber according to an embodiment of the present disclosure. As previously described, the refrigerator may be provided with cooling device and heating device that can be independently controlled to control the temperature of the storage chamber W. For example, the refrigerator may include the cooling device and the heating device for controlling the temperature of at least one storage chamber among a specific goods storage chamber, a constant temperature chamber, and a priority storage chamber. - The refrigerator may be controlled in a plurality of modes for temperature adjusting of the storage chamber W, and the plurality of modes may include a cooling mode E in which the storage chamber W is cooled by the cooling device, a heating mode H in which the storage chamber W is heated by the heating device, and a standby mode D which maintains the current state without cooling or heating the storage chamber W. The refrigerator may include a temperature sensor for sensing a temperature of the storage chamber W and may perform the cooling mode E, the heating mode H, and the standby mode D according to the storage chamber temperature sensed by the temperature sensor.
- The cooling mode E is not limited to the storage chamber W being continuously cooled by the cooling device and may include a case where the storage chamber is cooled by the cooling device as a whole, but the storage chamber W is temporarily not cooled by the cooling device and a case where the storage chamber W is cooled by the cooling device as a whole, but the storage chamber is temporarily heated by the heating device. The cooling operation E may include a case where the time when the storage chamber is cooled by the cooling device is longer than the time when the storage chamber W is not cooled by the cooling device.
- The heating mode H is not limited to the storage chamber W being continuously heated by the heating device and include a case where the storage chamber W is heated by the heating device as a whole, but the storage chamber W is temporarily not heated by the heating device and a case where the storage chamber W is heated by the heating device as a whole, the storage chamber W is temporarily cooled by the cooling device. The heating operation H may include a case where the time when the storage chamber W is heated by the heating device is longer than the time when the storage chamber W is not heated by the heating device.
- There is a case where the temperature of the storage chamber W, which has been temperature-controlled by the cooling mode E, may be kept below a target temperature lower limit value without lifting above the target temperature lower limit value for a long time in a state of being lowered below the target temperature lower limit value. In this case, the refrigerator may start the heating mode H so that the storage chamber W is not overcooled when the storage chamber temperature falls below the lower limit temperature, and the heating device can be turned on. The lower limit temperature may be a temperature set to be lower than the target temperature lower limit value by the predetermined temperature.
- Meanwhile, the refrigerator may start the heating mode H so that the storage chamber temperature is not maintained in a low state for a long time when the storage chamber temperature is maintained between the target temperature lower limit value and the lower limit temperature during the setting time. The heating mode H may be started when the storage temperature is the lower limit temperature, and the lower limit temperature may be the heating mode start temperature.
- One example of the standby mode D may be a mode in which the storage chamber temperature is maintained between the target lower limit value and the lower limit temperature, the refrigerator may be controlled in the order of the cooling mode E, the standby mode D, and the heating mode H without immediately switching to the heating mode H during the cooling mode E.
- Meanwhile, the temperature of the storage chamber W, which has been temperature-controlled by the heating mode H, may be kept above the target temperature upper limit value without being lowered below the target temperature upper limit value for a long time in a state of lifting above the target temperature upper limit value. In this case, when the storage chamber temperature exceeds the upper limit temperature, the refrigerator can start the cooling mode E so that the storage chamber W is not overheated, and the cooling device can be turned on. The upper limit temperature may be a temperature set to be higher than a target temperature upper limit value.
- Meanwhile, the refrigerator may start the cooling mode E so that the storage chamber temperature does not remain high for a long time when the storage chamber temperature is maintained between the target temperature upper limit value and the upper limit temperature during the setting time. The cooling mode E may be started if the storage temperature is the upper limit temperature, and the upper limit temperature may be the cooling mode start temperature.
- Another example of the standby mode D may be a mode in which the storage chamber temperature is maintained between the target temperature upper limit value and the upper limit temperature, and without switching to the cooling mode E immediately during the heating mode H, the refrigerator may be controlled in the order of the heating mode H, the standby mode D, and the cooling mode E.
- For example, the cooling mode E may be a mode in which the refrigerant passes through the evaporator, the air in the storage chamber W is cooled by the evaporator, and then flows into the storage chamber W. In the cooling mode E, the compressor may be turned on or off according to the temperature of the storage chamber W. In the cooling mode E, the compressor may be turned on or off such that the storage chamber temperature is maintained between the target temperature upper limit value and the target temperature lower limit value. Specifically, the compressor may be turned on because the cooling is not satisfied when the storage chamber temperature reaches the target temperature upper limit value and may be turned off when cooling is satisfied when the storage chamber temperature reaches the target temperature lower limit value.
- For example, in the heating mode H, the heater may be turned on or off so that the storage chamber temperature is maintained between the target temperature upper limit value and the target temperature lower limit value. Specifically, the heater may be turned off because heating is satisfied when the storage chamber temperature reaches the target temperature upper limit value and may be turned on because heating is not satisfied when the storage chamber temperature reaches the target temperature lower limit value.
- For example, the standby mode D may be a mode in which the refrigerant does not pass through the evaporator and the heater maintains the off state. The standby mode D may be a mode in which air in the storage chamber W is not forced to flow by the storage chamber fan. The standby mode D may be a mode in which the heater also maintains the off state while the compressor maintains the off state.
- The plurality of modes may further include a humidification mode for increasing the humidity of the storage chamber. The humidification mode may be a mode in which air in the storage chamber W may be humidified by flowing into the cooling device chamber by a fan, and the humidified air may flow into the storage chamber W to humidify the storage chamber, in a state where at least a portion of the cooling device is in an off state (for example, the supply of refrigerant to the evaporator is interrupted, the thermoelectric element is turned off), and at least some of the heating device is maintained in an off state (for example, the heater is turned off and the thermoelectric element is turned off).
- For example, the humidification mode may be a mode in which the air in the storage chamber flows to the evaporator by a fan to humidify, and the humidified air flows into the storage chamber to humidify the storage chamber, in a state where the heater maintains in an off state while the refrigerant does not pass through the evaporator. In the humidification mode, a fan that circulates air in the storage chamber to the evaporator and the storage chamber may be driven.

Fig. 9 is a control block diagram illustrating a refrigerator according to an embodiment of the present disclosure. The refrigerator may include acontroller 30 that controls various electronic devices such as a motor provided in the refrigerator. Thecontroller 30 may control the refrigerator according to the input value of the input device. - The input device may include at least one of a
communication device 31 which receives a signal from an external device such as a remote controller such as a remote controller or a mobile terminal such as a mobile phone, amicrophone 32 that changes a user's voice to a sound signal, asensing unit 33 which can sense a user's motion, a proximity sensor 34 (or a distance sensor) which can sense the user's proximity, atouch sensor 35 which can sense the user's touch, adoor switch 36 which can detect the opening and closing of the door, or atimer 37 which can measure the lapse of time. - As previously described, the refrigerator may include a see-through door. The see-through door may be a door that can selectively switched between a first state in which the door is at least partially transparent and a user can see through the door (a see-through activation state), and a second state in which the door is at least partially opaque and a user cannot see through the door (a see-through deactivation state). The see-through door may be a door that is changed from a see-through deactivation state to a see-through activation state or is changed from a see-through activation state to a see-through deactivation state according to an input value provided to the
controller 30 through the input device. In another example, the see-through door may be a door in which the see-through door is changed from see-through deactivation state to see-through activation state when the see-through door is closed and according to an input value provided to thecontroller 30 through the input device. - An example of an operation method according to the input device is now described. The
sensing unit 33 may include a vibration sensor. For example, the vibration sensor may be disposed on the rear surface of the front panel, and the vibration sensor may be formed in black such that visible exposure of the vibration sensor may be minimized. For example, thesensing unit 33 may include a microphone or other audio sensor disposed, for example, on the rear surface of the front panel, and the microphone may sense sound waves of vibration applied to the front panel. When a user provides a particular input, such as tapping the panel assembly 23 a plurality of times at a predetermined time interval, the specific input may be detected through thesensing unit 33, and thecontroller 30 may change the see-through door to be activated or deactivated based on the detected input. - Additionally or alternatively, the
sensing unit 33 may be a device for imaging a user's motion, such as a camera. It may be determined whether the image photographed by thesensing unit 33 is similar or identical to a specific motion input in advance, and thecontroller 30 may determine whether to activate or deactivate the see-through door according to the determination result. - Similarly, if it is determined that the user or a part of the user (e.g., the user's hand) is positioned within a predetermined distance or less (e.g., 30 cm or less) of a portion of the refrigerator according to the value detected by the
proximity sensor 34, the see-through door may be changed between the activated or deactivated states. In another example, the see-through door may be changed between the activated or deactivated states when it is determined that the user positioned with a predetermined distance or less and is moving toward the refrigerator according to the value detected by theproximity sensor 34. - In another example, when the
controller 30 determines that the door is closed according to the value detected by thedoor switch 36, the see-through door may be activated, and when it is determined that the door is open, the see-through door may be changed to be inactivated. For example, the see-through door may be in the deactivated state when opened and may remain in the deactivated state when closed, until a particular input is received that prompts the see-through door to be switched to the activated state. - The see-through door may be controlled to be deactivated after a certain time elapses after being activated according to the value input through the
timer 37. For example, the see-through door may be controlled to be deactivated after a certain time elapses after an input to activate the see-through door is received. In another example, according to the value input through thetimer 37, the see-through door may be controlled to be activated when a predetermined time elapses after being deactivated. - If the device for activating or deactivating the see-through door is defined as a transparency control module, for example, the
panel assembly 23 and thelight source 38 may be used. As an example in which the see-through door is activated or deactivated, there may be a case where the transparency of the see-through door itself may vary. For example, the see-through door may maintain in an opaque state when no current is applied to thepanel assembly 23 and may be changed to be transparent when current is applied to thepanel assembly 23. In another example, it can be a case that, when thelight source 38 installed inside the see-through door is turned on, the user may see the storage chamber through the see-through door by the light emitted from thelight source 38. - The
light source 38 may make thepanel assembly 23 appear transparent or translucent so that an inside of the refrigerator (a side of the storage chamber relative to the panel assembly) looks brighter than outside of the refrigerator (outside relative to the panel assembly). Thelight source 38 may be mounted on the light source mounting portion formed on thecabinet 1 or the light source mounting portion formed on the door and may be disposed to emit light toward thepanel assembly 23. - In other examples, the
controller 30 may control thedoor opening module 11 according to the input value of the input device. Thecontroller 30 may control thelifting module 13 according to the input value of the input device. -
Fig. 10 is a perspective view illustrating a see-through door of a refrigerator according to an embodiment of the present disclosure. The refrigerator may include a door (hereinafter, a see-through door) through which a user may view the storage chamber through a see-through window without opening thedoor 50 from the outside of the refrigerator. The see-through door may include anouter door 22 and apanel assembly 23. - The
outer door 22 may be opaque, and anopening portion 21 may be formed in (e.g., in a central region) of theouter door 22. Theouter door 22 may form an outer appearance of the see-through door. Theouter door 22 may be rotatably connected to or connected to thecabinet 1 to be capable of being advanced and retracted to open storage chamber W. Thepanel assembly 23 may be disposed in the openingportion 21. Thepanel assembly 23 may be disposed to shield the openingportion 21. Thepanel assembly 23 can form the same outer appearance as the front surface of theouter door 22. - The see-through door may be provided to open and close the storage chamber which mainly stores goods (for example, wine) having a large quality change according to the temperature change (e.g., the goods are preferable stored in a narrow temperature range to preserve a quality of the goods). In a case where goods having a large quality change due to temperature change are mainly stored in the storage chamber W, the storage chamber W is preferably opened and closed as short as possible, the number of opening and closing is preferably minimized, and the see-through door is preferably installed to open and close the storage chamber W. For example, the see-through door is may be provided in a door for opening and closing at least one of the specific goods storage chamber, the constant temperature chamber, and the priority storage chamber.
-
Fig. 11 is a plan view when an example of a swinging-type door according to an embodiment of the present disclosure is opened in a door opening module. In the refrigerator, a door opening and closing the storage chamber may be an automatic door, and the door for opening and closing the specific goods storage chamber, the constant temperature chamber, and a priority storage chamber may be an automatic door. The refrigerator may include adoor opening module 11 that provides a force for automatically opening thedoor 5. The automatic door may be controlled to be opened or closed according to an input value provided to thecontroller 30 through the input device. For this purpose, thecontroller 30 may control thedoor opening module 11. - The
cabinet 1 may be installed with ahinge mechanism 40 in which thehinge shaft 42 is connected to thedoor 5. The refrigerator may further include amodule cover 70 that may cover thehinge mechanism 40 and thedoor opening module 11 together. In addition, thedoor opening module 11 may include adrive motor 72, apower transmission unit 74, and apush member 76. - When the power of the refrigerator is turned on, the
controller 30 may wait to receive an open command of thedoor 5. When the door opening command is input through the input device, thecontroller 30 may transmit an opening signal to thedrive motor 72 included in thedoor opening module 11. - When the
controller 30 transmits an opening signal to thedrive motor 72, thedrive motor 72 may be rotated in a first direction to move thepush member 76 from the initial position to the door opening position. When thedrive motor 72 rotates in the first direction, thepower transmission unit 74 may transmit a first direction rotational force of thedrive motor 72 to thepush member 76, and thepush member 76 may push the door while protruding forward, and thedoor 5 may be rotated in the forward direction with respect to thecabinet 1. - The
controller 30 may determine whether thepush member 76 has reached the door opening position in a process of rotating in the first direction of thedrive motor 72. For example, the controller may determine that thepush member 76 has reached the door opening position when the cumulative rotational speed of thedrive motor 72 reaches the reference rotational speed. Thecontroller 30 may stop the rotation of thedrive motor 72 when it is determined that thepush member 76 has moved to the door opening position. - In a state where the
door 5 is rotated by a predetermined angle, the user can manually increase the opening angle of thedoor 5. When the user increases the opening angle of the door in a state where thepush member 76 moves thedoor 5 to the door opening position, the door sensor including amagnet 46 and areed switch 48 can sense the manual opening of thedoor 5, and if the manual opening of thedoor 5 is sensed by the door sensor, thecontroller 30 can output a return signal to thedrive motor 72. - The
controller 30 may transmit the return signal to thedrive motor 72 so that thepush member 76 returns to the initial position and thedrive motor 72 may be reversely rotated in a second direction opposite to the first direction. If it is determined that thepush member 76 has returned to the initial position, thecontroller 30 may stop thedrive motor 72. -
Fig. 12 is a sectional view when another example of a door according to an embodiment of the present disclosure is opened by a door opening module 11'. In the example shown inFig. 12 , the door is drawer that may be automatically opened by the door opening module 11' that applies an outward force. - The door opening module 11' illustrated in
Fig. 12 may automatically open the door (or drawer) 6 disposed in thecabinet 1 to be capable of being advanced and retracted. The refrigerator may include a first door provided at a relatively higher at a greater height and a second door that is relatively lower and having a smaller height, and the door opening module 11' may be installed to automatically open a door having a lower height than other doors. Such a door may be a retractable automatic door which is automatically opened by the door opening module 11'. Thedoor 6 advanced and retracted by the door opening module 11' may include adrawer body 6A and adoor body 6B disposed at thedrawer body 6A to open and close the storage chamber. - The door opening module 11' may include a
drive motor 80, apinion 82, and arack 84. Thepinion 82 may be connected to the rotation shaft of thedrive motor 80. Therack 84 may extend from thedoor 6, such as thedrawer body 6A. The refrigerator may further include a door sensor that senses a position of thedoor 6, and the door sensor may sense a pair of magnets 46' spaced apart from thedoor 6 and a reed switch (or Hall sensor) 48' sensing the magnet 46'. - When the power of the refrigerator is turned on, the
controller 30 may wait to receive an opening command of thedoor 6. When the door opening command is input through the input device, thecontroller 30 may transmit an opening signal to thedrive motor 80. - The
drive motor 80 may be activated to rotate in the first direction by thecontroller 30 when an opening signal is input, and thepinion 82 and therack 84 may transmit the rotational force of thedrive motor 80 to thedrawer body 82. Thedrawer body 6A may advance thedoor body 6B while advancing forward in the storage chamber, and thedoor body 6B can be advanced to be spaced apart from thecabinet 1 toward the front of thecabinet 1. Thecontroller 30 may sense that thedoor 6 has reached the opening position by the door sensor, and when thedoor 6 has reached the opening position, thecontroller 30 may stop the rotation of thedrive motor 80. - When the
drawer body 6A is advanced as described above, the upper surface of thedrawer body 6A may be exposed. In a state where thedrawer body 6A is advanced to the opening position, the user can enter a door closing command such that thedrawer body 6A retracts to the closing position via the input device. For example, if the motion sensed by thesensing unit 33 coincides with a specific motion, thecontroller 30 may transmit a close signal to thedrive motor 80. In another example, thecontroller 30 may sense the proximity of the user by theproximity sensor 34 and transmit a closing signal to thedrive motor 80 when theproximity sensor 34 detects that the user has moved more than a predetermined distance (e.g., toward the proximity sensor 34). - When the close signal is input, the
drive motor 80 may be reversely rotated in a second direction opposite to the first direction. In reverse rotation of thedrive motor 80, thepinion 82 and therack 84 can transmit the rotational force of thedrive motor 80 to thedrawer body 6A, and while thedrawer body 6A retracts into the storage chamber, thedoor body 6B can be retracted and thedoor body 6B can be retracted in close contact with thecabinet 1 toward the front of thecabinet 1. Thecontroller 30 may sense that thedoor 6 has reached the closing position by the door sensor, and if thedoor 6 has reached the closing position, thecontroller 30 may stop the reverse rotation of thedrive motor 80. -
Fig. 13 is a sectional view illustrating when theholder 12 lifts while the door is opened according to the embodiment of the present disclosure. As previously described, the refrigerator may further include a lifting module (also referred to as a lift or elevator) 13 which allows theholder 12 to be automatically lifted and lowered after theholder 12 is moved forward in a state where thedoor 50 is opened. Theholder 12 may be a shelf, a drawer, a basket, or the like on which goods can be placed. Thelifting module 13 may be disposed in the storage chamber or at least one of therotatable door 5 and the advancing and retractingtype door 6 for opening and closing the storage chamber. The refrigerator may have both a first holder provided higher at a greater height and a second holder provided lower at a smaller lower height. - The
lifting module 13 may be disposed in a low storage chamber associated with aholder 12 having a lower height thanother holders 12. In another example, thelifting module 13 may function for lowering a holder and may be arranged in a storage chamber in which a holder having a relatively greater height than other holders is located. - An example of the
lifting module 13 will be described. An example of thelifting module 13 may include alower frame 93, anupper frame 94, a lifting and loweringmechanism 92 having at least onelink 95, and adrive mechanism 90 capable of lifting and lowering theupper frame 94. Thedrive mechanism 90 may include a lifting and loweringmotor 91 and a power transmission member connected to the lifting and loweringmotor 91 to transfer the drive force of the lifting and loweringmotor 91 to theupper frame 94. - When the refrigerator is turned on, the
controller 30 may wait for a lifting command of theholder 12 to be input. When the lifting command is input through the input device, thecontroller 30 may transmit a lifting signal to the lifting and loweringmotor 91 included in thelifting module 13. When thecontroller 30 transmits an opening signal to the lifting and loweringmotor 91, theupper frame 94 may lift, and theholder 12 may be lifted to the upper side of thedrawer body 6B. - The user may input a lowering command through the input device, and the
controller 30 may transmit a lowering signal to the lifting and loweringmotor 91 when the lowering command is input through the input device. In another example, thecontroller 30 may automatically generate the lowering command when a lifted drawer is being closed or other, higher drawers start to be closed. For example, the lifting and loweringmotor 91 may be reversely rotated in a second direction opposite to the first direction. Upon reverse rotation of the lifting and elevatingmotor 91, theupper frame 94 may be lowered to the inner lower portion of thedrawer body 82, and theholder 12 may be inserted into thedrawer body 6B together with theupper frame 94. -

For convenience, the temperature control device disposed in the air flow path P will be described with the
same reference numeral 150 as the evaporator, which is provided as an example of the temperature control device. Hereinafter, the airflow forming mechanism disposed in the air flow path P will be described as thefan 181. - When the storage chamber W is opened, the front surface of the
inner guide 200 may face the front of the storage chamber W. Theinner guide 200 may be formed so that its front surface has a substantially planar shape. Theinner guide 200 may further include a portion (that is, a bent portion or region) that is bent at another portion of the periphery or a portion (that is, a protrusion portion) that protrudes more than the other portion of the periphery. - When the
inner guide 200 is a combination of a plurality of members, the boundary L of the plurality of members or the coupling portion of the plurality of members may be positioned the rear or the side of another structure (for example, theshelf 2, thepartition member 3, receivingmember 4, or the like) disposed inside the storage chamber W, and thus may be concealed by the other configuration or located close to the other configuration. When the boundary L or the coupling portion is minimized, the outer appearance of theinner guide 200 may be simplified, and the refrigerator may be advanced. - Hereinafter, the detailed structure of the
inner guide 200 is described. Theinner guide 200 may function to define a discharge duct for discharging air into the storage chamber W and may function to define a suction duct for returning the air in the storage chamber W to thetemperature adjusting device 150. For example, theinner guide 200 may have adischarge port 204 and asuction port 205, and thedischarge hole 204 and thesuction port 205 may be formed to be spaced apart from theinner guide 200. When the suction port is not visible as much as possible in front of the storage chamber W as described above, the outer appearance of theinner guide 200 may be more concise, and the refrigerator may be advanced. - The refrigerator may further include a
partition member 3 disposed in the storage space to partition the storage space into a first space W1 and a second space W2. Thepartition member 3 may be closer to the lower end of the upper and lower ends of the storage chamber. - In the refrigerator, a discharge port 204 (hereinafter, referred to as a first discharge port) for discharging air into the first space W1 and a suction port 205 (hereinafter, referred to as a first suction port) for suctioning air in the first space W1 may be formed at a position facing the first space W1. In the refrigerator, an additional discharge port 321 (hereinafter, referred to as a second discharge port) for discharging air into the second space W2 and an additional suction port 341 (hereinafter, referred to as a second suction port) formed in a
guide 340 for suctioning air in the second space W2 may be formed at a position facing the second space W2. The first discharge port may be provided at a position higher than the first suction port. The second discharge port may be provided at a position higher than the second suction port. - One surface of the
partition member 3 may be a suction guide surface for guiding air flowing toward thesuction port 205, and the other surface of thepartition member 3 may be a discharge guide surface for guiding air discharged to theadditional discharge port 321. Thepartition member 3 may be spaced apart from thesuction port 205 in the horizontal direction and may be disposed to cover a portion of thesuction port 205. At least a portion of thesuction port 205 may face thepartition member 3 in the horizontal direction. - The gap between the
partition member 3 and thesuction port 205 may function as an inlet passage through which air in the first space W1 passes to be suctioned into thesuction port 205, and the air in the first space W1 may be suctioned to thesuction port 205 after passing through the gap between thepartition member 3 and thesuction port 205. As described above, when a portion of thesuction port 205 is covered by thepartition member 3, the outer appearance of thesuction port 205 may be more advanced than when theentire suction port 205 is visible through the periphery of thepartition member 3. - Meanwhile, the
inner guide 200 may have a heat exchange flow path P1 in which thetemperature adjusting device 150 and thefan 181 are received. Theinner guide 200 may have a discharge flow path P2 through which air blown by thefan 181 is guided to thedischarge port 204.
