Hereinafter, the present disclosure will be described in more detail with reference to the drawings.

1 is a block diagram illustrating a simple configuration of a wine cellar according to an embodiment of the present disclosure.

Referring to FIG. 1, the wine cellar 100 includes a storage compartment 110, a cooling device 120, a heating device 130, a fan 140, a temperature sensor 150 and a processor 160.

The storage room 110 is disposed inside the wine cellar 100 to store food. The storage chamber 110 is maintained at about 4°C to 7°C to store champagne, or about 8°C to 13°C to store white wine, or 14°C to 18°C to store red wine Can.

In addition, a plurality of storage rooms 110 may be disposed to store different foods. For example, a plurality of storage chambers 110 may be arranged to store wines for each type, and may respectively store champagne, white wines, and red wines. And it can be maintained in a different temperature range for each storage room.

In addition, the storage compartment 110 is provided with an open front surface for putting food in and out, and the opened front surface can be opened and closed by a door (not shown). In the storage room 110, a shelf or the like on which food can be placed may be disposed.

The cooling device 120 supplies cooled air to the storage chamber 110. Specifically, the cooling device 120 may supply cooled air to the storage chamber 110 so that the temperature of the storage chamber 110 decreases under the control of the processor 160. To this end, the cooling device 120 may include a compressor (not shown), a condenser (not shown), and an evaporator (not shown).

First, the compressor can compress the gaseous refrigerant at high pressure. In addition, the condenser may apply high pressure so that the compressed gas refrigerant changes to a liquid state. And the evaporator can apply a low pressure so that the refrigerant in the liquid state vaporizes again. At this time, the refrigerant may vaporize again and absorb heat from the surrounding air. In addition, ambient air in which heat is absorbed may be provided to the storage chamber 110.

In addition, the cooling device 120 may include a Peltier element or a thermoelectric element in addition to the examples described above to supply cooled air.

The heating device 130 supplies heated air to the storage chamber 110. Specifically, the heating device 130 may supply heated air to the storage chamber 110 to increase the temperature of the storage chamber 110 under the control of the processor 160. To this end, the heating device 130 may include a heater (not shown). The heater may be a heating element that directly generates heat by receiving power. Alternatively, the heater may be implemented using a Peltier element or a thermoelectric element.

The fan 140 circulates the outside air of the wine cellar 100 and the inside air of the storage chamber 110. Specifically, the fan 140 sucks external air through the intake port of the wine cellar 100 under the control of the processor 160, and discharges the internal air through the discharge port of the wine cellar 100, thereby allowing the external air and internal air. Air can be circulated.

In addition, as the fan 140 circulates external air and internal air, the temperature and humidity of the storage chamber 110 may be changed. For example, when the outside air of the wine cellar 100 is dry air at 10°C and the inside air is humid air at 15°C, the outside air is sucked by the fan 140 and the inside air is discharged to store the chamber 110 Both temperature and humidity of can be lowered.

The temperature sensor 150 may detect the temperature inside the wine cellar 100. Specifically, the temperature sensor 150 may be disposed inside the storage chamber 110 to sense the temperature of the storage chamber 110. Alternatively, the temperature sensor 150 may be disposed outside the wine cellar 100 to sense the external temperature of the wine cellar 100.

In addition, a plurality of temperature sensors 150 may be disposed to simultaneously sense a plurality of temperatures. Also, the temperature sensor 150 may provide the sensed temperature information to the processor 160.

The processor 160 performs control for each component in the wine cellar 100. Specifically, when receiving a command for a specific function, the processor 160 may control an operation of a configuration related to performance of the corresponding function.

More specifically, when the processor 160 receives a command corresponding to the set temperature for the storage chamber 110, the processor 160 controls the cooling device 120 or the heating device 130 so that the temperature of the storage room 110 can maintain the set temperature. can do.

Meanwhile, the processor 160 may determine an operation mode of the wine cellar 100 before controlling the cooling device 120 or the heating device 130. Here, the operation mode is cooling to lower the temperature of the storage compartment 110 by supplying cooled air to the storage compartment 110 and heating to increase the temperature of the storage compartment 110 by supplying heated air to the storage compartment 110 ( Heating) mode, and is not limited to the above-described example.

Specifically, the processor 160 may determine an operation mode based on the detected temperature of the storage chamber 110 and the set temperature of the storage chamber 110.

More specifically, when the temperature of the storage chamber 110 is higher than a set temperature for the storage chamber 110, the processor 160 may determine an operation mode as a cooling mode. In addition, when the temperature of the storage chamber 110 is lower than the set temperature, the processor 160 may determine an operation mode as a heating mode.

For example, when the temperature of the current storage chamber 110 is 10°C and the set temperature is 16°C, the processor 160 may determine the operation mode as the heating mode. As another example, when the temperature of the current storage chamber 110 is 16°C and the set temperature is 10°C, the processor 160 may determine an operation mode as a cooling mode.

In addition, the processor 160 may selectively control the cooling device 120 or the heating device 130 based on the determined operation mode. Specifically, the processor 160 may control the cooling device 120 when the determined operation mode is the cooling mode, and control the heating device 130 when the determined operation mode is the heating mode.

More specifically, when the determined operation mode is the cooling mode, the processor 160 controls the cooling device 120 to supply the cooled air to the storage chamber 110 so that the temperature of the storage chamber 110 reaches a lower set temperature. Can.

In addition, when the determined operation mode is the heating mode, the processor 160 may control the heating device 130 to supply the heated air to the storage chamber 110 so that the temperature of the storage chamber 110 reaches a higher set temperature.

Meanwhile, the processor 160 may control the fan 140 to be driven before controlling the heating device 130 to supply heated air to the storage compartment 110. Specifically, when the determined operation mode is the heating mode, the processor 160 may control to first drive the fan 140 so that the outside air of the wine cellar 100 flows into the interior of the storage chamber 110.

Here, the reason for driving the fan 140 before controlling the heating device 130 is to discharge the inside air of the storage room having a high humidity due to the operation of the cooling device to the outside of the wine cellar and discharge the outside air having a relatively low humidity. This is to lower the humidity of the storage room by inhaling it into the wine cellar. When the humidity in the storage compartment is lowered, dew condensation in the wine cellar can be prevented.

Meanwhile, a dew condensation phenomenon and a dew condensation removal method will be described later with reference to FIGS. 3 and 4.

In addition, the processor 160 may control the heating device 130 to start supplying heated air during the operation of the fan 140 that lowers the humidity of the storage chamber 110.

Specifically, the processor 160 may control the fan 140 for a predetermined time, and may control the heating device 130 to start supplying heated air after a predetermined time. Here, the preset time is an average time required to lower the humidity of the storage chamber 110 to a specific humidity that can prevent dew condensation. The preset time may be 30 minutes, 1 hour, and the like, but is not limited thereto.

In addition, when the temperature of the storage chamber 110 reaches a set temperature, the processor 160 may control the cooling device 120 or the heating device 130 so that the temperature of the storage room 110 maintains the set temperature. Specifically, the processor 160 controls the cooling device 120 or the heating device 130, and when the temperature of the storage compartment 110 reaches a set temperature, the storage compartment 110 is considered in consideration of the external temperature of the wine cellar 100 The cooling device 120 or the heating device 130 may be controlled to maintain the set temperature of.

If the external temperature of the wine cellar 100 is higher than the set temperature, the processor 160 may control the cooling device 120 to maintain the set temperature. For example, when the external temperature is 15°C and the set temperature is 4°C, the temperature of the storage chamber 110 is increased due to the external influence of the wine cellar 100, so that the processor 160 cools the cooling device 120. By using it, the temperature of the storage chamber 110 can be maintained at a set temperature.

On the other hand, when the external temperature of the wine cellar 100 is lower than the set temperature, the processor 160 may control the heating device 130 to maintain the set temperature. For example, when the external temperature is 10°C and the set temperature is 15°C, the temperature of the storage chamber 110 is lowered due to the external influence of the wine cellar 100, so the processor 160 uses the heating device 130 By doing so, the temperature of the storage chamber 110 can be maintained at a set temperature.

In addition, the processor 160 may control the cooling device 120 or the heating device 130 and the fan 140 at the same time. Specifically, the processor 160 controls the cooling device 120 so that the cooled air is supplied to the storage compartment 110, and at the same time, the fan 140 is provided so that the cooled air is evenly distributed inside the storage compartment 110. Can be controlled. In addition, the processor 160 controls the heating device 130 to supply heated air to the storage compartment 110 and at the same time, to control the fan 140 so that the heated air can be evenly distributed inside the storage compartment 110. Can.

On the other hand, in the above, only a simple configuration constituting a wine cellar has been illustrated and described, but in the implementation, various configurations may be additionally provided. This will be described below with reference to FIG. 2.

2 is a block diagram showing a specific configuration of a wine cellar according to an embodiment of the present disclosure.

Referring to FIG. 2, a wine cellar 100 according to an embodiment of the present disclosure includes a storage room 110, a cooling device 120, a heating device 130, a fan 140, a temperature sensor 150, a processor ( 160), a humidity sensor 170, an input device 180, and a memory 190.

The storage room 110, the cooling device 120, the heating device 130, and the fan 140 perform the same functions as the configuration of FIG. 1, so duplicate description is omitted. Also, since the processor 160 has been described in connection with FIG. 1, the contents described in FIG. 1 are not described repeatedly, and only the contents related to the configuration added to FIG. 2 will be described below.

The humidity sensor 170 can detect the high humidity inside the wine cellar 100. Specifically, the humidity sensor 170 is disposed inside the storage chamber 110 to detect the humidity of the storage chamber 110. In addition, a plurality of humidity sensors 170 may be disposed to simultaneously sense a plurality of humidity. In addition, the humidity sensor 170 may provide the detected humidity information to the processor 160.

In addition, the processor 160 may control the fan 140 using the detected humidity information of the storage room 110. Specifically, when the operation mode of the wine cellar 100 is determined as a heating mode, the processor 160 first controls the fan 140 so that external air flows into the storage chamber 110 in order to lower the humidity of the storage chamber 110. can do. In addition, the processor 160 may control the heating device 130 to start supply of heated air when the humidity of the storage chamber 110 reaches a predetermined humidity during the operation of the fan 140.

Here, the preset humidity means sufficient humidity to prevent dew condensation. In addition, the preset humidity may be set in consideration of the external temperature and the set temperature of the wine cellar 100. In addition, the preset humidity may be set to a fixed value such as 75%, but is not limited thereto.

In addition, when the humidity sensor 170 has a plurality of humidity sensors 170, when the humidity of each of the plurality of humidity sensors detected during operation of the fan 140 reaches a predetermined humidity, a heating device is provided to start supplying heated air. 130 can be controlled.

The input device 180 may include a plurality of function keys that the user can set or select various functions supported by the wine cellar 100. Through this, the user can input various driving commands for the wine cellar 100.

Specifically, the user may input a storage mode corresponding to the type of food through the input device 180. For example, if the wine cellar 100 is a wine cellar, the user may select one of a champagne storage mode for storing champagne, a white storage mode for storing white wine, and a red wine storage mode for storing red wine. You can choose. Meanwhile, the user may directly input the set temperature of the storage room 110 through the input device 180 in addition to the storage mode corresponding to the type of food.

Further, the processor 160 may control the cooling device 120 or the heating device 130 to have a temperature corresponding to a storage mode or a set temperature input through the input device 180.

For example, when the champagne storage mode is input, the processor 160 may control the cooling device 120 or the heating device 130 so that the temperature of the storage room 110 satisfies 4°C to 7°C. As another example, when 10°C is input as the set temperature, the processor 160 may control the cooling device 120 or the heating device 130 so that the temperature of the storage chamber 110 satisfies 10°C.

In addition, when a new command for a set temperature is input through the input device 180, the processor 160 may determine an operation mode of the wine cellar 100 to have a temperature corresponding to the new set temperature. In addition, the cooling device 120 or the heating device 130 may be selectively controlled based on the determined operation mode.

In addition, the input device 180 may be implemented in the form of a touch screen capable of simultaneously performing a function of a display (not shown) that displays various information provided by the wine cellar 100.

The memory 190 stores various data for the operation of the wine cellar 100 in general, such as a program for processing or controlling the processor 160. Specifically, the memory 190 may store a number of application programs driven by the wine cellar 100 and data and instructions for the operation of the wine cellar 100.

Further, the memory 190 is accessed by the processor 160, and data read/write/modify/delete/update by the processor 160 may be performed. The memory 190 may be implemented as a storage medium in the wine cellar 100, as well as an external storage medium, a removable disk including a USB memory, and a web server through a network.

In addition, the memory 190 may store information about a set temperature corresponding to the type of food. For example, the wine cellar 100 may provide a plurality of storage modes according to the type of wine, and the memory 190 may store information about a set temperature corresponding to the plurality of storage modes.

Specifically, in the case of a champagne storage mode for managing champagne, the memory 190 may store 4°C to 7°C in a range of a set temperature, and in the case of a white wine storage mode for managing white wine, 8°C to 13 °C can be stored in the range of the set temperature, and in the case of the red wine storage mode for managing red wine, 14 °C to 18 °C can be stored in the range of the set temperature.

On the other hand, in the illustration and description of FIG. 2, only the above-described configuration is illustrated and described, but in implementation, a configuration such as a communication device (not shown) and a display (not shown) may be additionally provided.

Conventionally, when the operation mode of the wine cellar is determined as the heating mode, the heating device is operated immediately. At this time, when the temperature of the storage chamber is higher than the external temperature in a state where the humidity of the storage chamber is high due to moisture implanted in the evaporator of the cooling device, dew condensation occurs.

On the other hand, as described above, in the wine cellar according to the present embodiment, when the operation mode of the wine cellar is determined to be the heating mode, the fan is operated first to lower the humidity of the storage compartment by lowering the humidity of the storage compartment by operating the fan first. Even when it is higher than the outside temperature, it may have an effect of preventing dew condensation.

3 is a view for explaining a conventional dew condensation phenomenon.

Referring to FIG. ³ , a graph of the amount of water vapor (g/m ³ ) according to the temperature (°C) for each relative humidity (%) can be confirmed.

The amount of water vapor that air can contain varies depending on the temperature. At this time, the maximum amount of water vapor that can be contained in the air having a volume of 1 m ³ at a constant temperature is referred to as a saturated water vapor amount, and a value representing a ratio of the amount of water vapor contained in the air having a volume of 1 m ³ and the amount of saturated water vapor in% is referred to as relative humidity. That is, the relative humidity can be expressed by the following equation.

Relative humidity (%) = current water vapor (g/m ³ ) / saturated water vapor at current temperature (g/m ³ )

The relative humidity increases as the amount of water vapor contained in the air increases, and decreases as the amount of saturated water vapor increases. In addition, the amount of saturated water vapor increases as the temperature increases.

In addition, when the amount of water vapor contained in the air is the maximum amount of water vapor, it is referred to as saturation, and corresponds to a relative humidity of 100%. At this time, if the temperature is lowered for some reason without changing the amount of water vapor, the amount of saturated water vapor decreases, and part of the water vapor contained in the air condenses.

For example, when the current temperature is 20°C, the saturated water vapor amount is 17.3 g/m ³ . However, when the temperature is lowered to 10° C., the saturated water vapor amount becomes 9.4 g/m ³ , and condensation may occur due to condensation of some water vapor (17.3 – 9.4 = 7.9 g/m ³ ).

The same principle can be applied to wine sellers. Hereinafter, a dew condensation phenomenon that may occur in a conventional wine cellar will be described with reference to FIG. 3.

In the related art, when the temperature of the storage room is lower than the set temperature, the processor determines the operation mode as the heating mode, and controls the heating device to operate immediately or controls the heating device and the fan to operate simultaneously.

On the other hand, when the operation mode of the wine cellar is determined to be a heating mode after the operation of the cooling device, and the heating device operates immediately, the moisture installed on the evaporator of the cooling device due to the operation of the previous cooling device is heated by the heating device. Due to evaporation, high-humidity steam enters the storage chamber, and the humidity in the storage chamber rises. And when there is a lot of moisture implanted in the evaporator, the humidity in the storage room can reach 100% relative humidity.

Of course, the temperature of the storage chamber increases due to the operation of the heating device, and the amount of saturated water vapor also increases, but when water vapor is continuously supplied due to the moisture condensed in the evaporator, the humidity can be maintained at a saturation of 100%.

In addition, the temperature of the storage room may continuously increase, and may be higher than the external temperature of the wine cellar. At this time, in the case of air located at an externally affected area where the temperature is low, for example, air located on the inner surface of the housing of the wine cellar, heat is taken out to lower the temperature.

The air that has been deprived of heat is reduced due to the decrease in temperature, which is the maximum amount of water vapor that can be included at the temperature. Therefore, some of the water vapor contained in the deprived air may condense to form dew.

For example, when the temperature of the air deprived of heat decreases to the temperature of the outside air, the amount of saturated water vapor of the air deprived of heat decreases to the amount of saturated water vapor corresponding to the temperature of the outside air, and the deprived air Among the water vapors included, condensation may occur due to condensation of the water vapor amount exceeding the saturated water vapor amount corresponding to the temperature of the outside air.

Specifically, referring to FIG. 3, it can be seen that due to the operation of the cooling device, the initial temperature of the storage compartment is 4°C, the external temperature is 15°C, and the set temperature is 18°C. And it can be confirmed that the relative humidity is 100% due to the increase in the humidity of the storage chamber due to the operation of the previous cooling device.

In addition, as the heater device operates, the temperature of the storage chamber rises, and the humidity can be maintained at 100% due to the supply of moisture implanted in the evaporator of the cooling device.

In addition, as the heating device continuously operates, dew condensation occurs as the temperature of the storage chamber becomes higher than the external temperature of 15°C. Specifically, as the air located on the inner surface of the wine cellar housing is lowered due to the influence of a low temperature outside, the amount of water vapor equal to the difference between the amount of water vapor in the storage chamber and the amount of saturated water vapor corresponding to the outside temperature condenses to cause dew condensation. do.

In particular, the wine cellar 100 is provided with a glass window so that the user can check the wine placed in the storage room, and a dew condensation occurs on the glass window, causing inconvenience that the user cannot check the wine.

And the heating device performs an operation of maintaining the corresponding temperature when it reaches the set temperature of 18°C. At this time, since the fans operate together, dry outside air is continuously introduced, and the amount of water vapor in the air gradually decreases.

On the other hand, the above-described dew condensation phenomenon may occur even when the humidity in the storage room is lower than 100%. For example, even when the humidity of the storage compartment is 90%, when the temperature of the storage compartment rises above the external temperature and the amount of water vapor in the storage compartment is greater than the saturated water vapor amount corresponding to the external temperature, dew condensation may occur on the inner surface of the housing of the wine cellar. have. The dew condensation phenomenon may mainly occur in the dew condensation region of FIG. 3, but this is only one example, and the dew condensation region may be different depending on the humidity of the external air and the amount of moisture condensed on the evaporator.

As described above, there has been a problem in that consumer inconvenience occurs due to dew condensation as the heating device operates immediately after the cooling device is operated.

Hereinafter, a method of removing the dew condensation described above using a fan will be described.

4 is a view for explaining a dew condensation removal method according to an embodiment of the present disclosure.

Referring to FIG. 4, it can be seen that due to the operation of the cooling device 120, the initial temperature of the storage chamber 110 is 4°C, the temperature of the external air is 15°C, and the set temperature is 18°C. And it can be confirmed that the relative humidity is 100% due to the increase in the humidity of the storage chamber 110 due to the operation of the previous cooling device 120.

In addition, the processor 160 may control the fan 140 before controlling the operation of the heating device 130. Due to the operation of the fan 140, the outside air of the wine cellar 100 may be sucked and the inside air of the storage chamber 110 may be discharged. At this time, as the outside air having high temperature is sucked, the temperature of the storage chamber 110 rises.

On the other hand, since the external air has a relatively low humidity compared to the internal air, the external air with low humidity continuously enters the storage chamber 110 due to the operation of the fan 140. However, due to the supply of moisture implanted in the evaporator of the cooling device 120, the humidity of the storage chamber 110 may still be maintained at 100%.

In addition, when the fan 140 is continuously operated, all of the implanted moisture is evaporated, so that the additional moisture supply is eliminated in the storage chamber 110, and external humidity with relatively low humidity is continuously supplied, so that the humidity of the storage chamber 110 is lowered. Start doing.

In FIG. 4, although the humidity of the storage chamber 110 decreases after the temperature of the storage chamber 110 reaches the external temperature of 15° C., the external temperature according to the amount of moisture implanted in the evaporator of the cooling device 120. Humidity of the storage chamber 110 may drop before reaching.

And when the humidity of the storage chamber 110 is sufficiently low, the operation of the heating device 130 is started, and even if the temperature of the storage chamber 110 increases, the amount of water vapor in the storage chamber does not exceed the amount of saturated water vapor corresponding to the external temperature, causing dew condensation. This may not happen.

Accordingly, when it is determined that the humidity of the storage chamber 110 is sufficiently low, the processor 160 may control to start the operation of the heating device 130.

At this time, a criterion for determining whether the humidity of the storage chamber 110 is sufficiently low by the processor 160 may be whether or not a predetermined humidity sufficient to prevent dew condensation is reached through the humidity sensor 170. . Here, the preset humidity may be set in consideration of the external temperature and the set temperature of the wine cellar 100. In addition, the preset humidity may be set to a fixed value such as 75%, but is not limited thereto.

If the humidity of the storage room 110 reaches a preset humidity, the processor 160 may control the heating device 130 to start an operation. On the other hand, when the humidity of the storage chamber 110 does not reach a preset humidity, the processor 160 may control the operation of the fan 140 until the humidity of the storage chamber 110 reaches a preset humidity.

Alternatively, a criterion for determining whether the humidity of the storage chamber 110 is sufficiently low by the processor 160 may be whether the fan 140 is operated for a predetermined time. Here, the preset time is an average time required to lower the humidity of the storage chamber 110 to a specific humidity that can prevent dew condensation. The preset time may be 30 minutes, 1 hour, and the like, but is not limited thereto.

If the operation time of the fan 140 reaches a preset time, the processor 160 may control the heating device 130 to start operation. On the other hand, when the operation time of the fan 140 reaches a predetermined time, the processor 160 may control the operation of the fan 140 until the predetermined time is reached.

Alternatively, the criterion for determining whether the humidity of the storage chamber 110 is sufficiently low by the processor 160 is whether the predetermined humidity is reached through the humidity sensor 170 after the fan 140 operates for a predetermined time. Can be.

If the humidity of the storage chamber 110 reaches a preset humidity after the fan 140 operates for a preset time, the processor 160 may control the heating device 130 to start operating. On the other hand, if the humidity of the storage chamber 110 does not reach the preset humidity after the fan 140 operates for a preset time, the processor 160 may control the fan 140 to operate again for a preset time. .

On the other hand, the criteria for determining whether the humidity of the storage room 110 is sufficiently low and the measures of the processor 160 when the standards are not satisfied are not limited to the above-described examples.

In addition, the processor 160 may operate the heating device 130 to increase the temperature of the storage chamber 110 to a preset temperature of 18°C. In addition, the processor 160 may operate the fans 140 at the same time so that the heated air is evenly supplied inside the storage compartment 110. At this time, external air having a relatively low temperature may be introduced, but the influence of the external air may be canceled due to the operation of the heating device 130.

In addition, the processor 160 may control the cooling device 120 or the heating device 130 to maintain the temperature of the storage chamber 110 when it reaches a set temperature. Specifically, referring to FIG. 4, since the external temperature is lower than the set temperature, the processor 160 may control the heating device 130 to maintain the set temperature.

On the other hand, in the description of FIG. 4, the humidity of the storage compartment is increased due to moisture implanted in the evaporator of the cooling device. have.

5 and 6 are diagrams for explaining the operation of the heating mode according to an embodiment of the present disclosure.

5 is a diagram for explaining an algorithm of a heating mode.

Referring to FIG. 5, first, the processor 160 may check whether the conditions of the heating mode are satisfied (S510). Specifically, the processor 160 may check whether the condition of the heating mode is satisfied according to whether the temperature of the storage chamber 110 is lower than the set temperature.

And when the condition of the heating mode is satisfied (S510-Y), the processor 160 may additionally check whether the previous operation mode is the cooling mode (S520).

If the previous operation mode is the cooling mode (S520-Y), dew condensation may occur due to moisture implanted in the evaporator of the cooling device 120. Therefore, the processor 160 may determine that it is necessary to remove dew condensation when the previous operation mode is the cooling mode, and may drive the fan 140 for a predetermined time so that the humidity of the storage compartment 110 is lowered (S530). ). Here, the preset time may be 1 hour, and is not limited to the above-described example.

In addition, the processor 160 may check whether the humidity of the storage room 110 is less than a preset humidity (S540). If the humidity of the storage room 110 is greater than a preset humidity (S540-N), the processor 160 may control the fan 140 to operate again for a preset time. On the other hand, when the humidity of the storage chamber 110 is smaller than a preset humidity (S540-Y), the processor 160 may control the heating device 130 to start an operation.

On the other hand, the processor 160 is a humidity sensor for a predetermined time, not a method of controlling to start the operation of the heating device 130 according to whether the humidity of the storage room 110 after a predetermined time is less than a predetermined humidity According to whether the average humidity of the storage chamber 110 sensed at 170 is less than a predetermined humidity, it may also be implemented in a manner of controlling to start the operation of the heating device 130.

Alternatively, the plurality of humidity sensors 170 are respectively disposed at different locations in the storage room 110, and the plurality of humidity sensed by the plurality of humidity sensors 170 after a predetermined time by the processor 160 is greater than the preset humidity. Depending on whether it is small or not, it may also be implemented in a manner of controlling to start the operation of the heating device 130.

On the other hand, when the previous operation mode is the heating mode (S520-N), there is no moisture condensed on the evaporator of the cooling device 120, so the possibility of dew condensation is low. Therefore, the processor 160 may determine that there is no need to perform an operation for removing dew condensation when the previous operation mode is a heating mode, and may control the heating device 130 to operate immediately (S550).

6 is a view for explaining the operation of the fan and the heating device.

Referring to FIG. 6, first, it can be seen that the fan 140 and the heating device 130 wait in an OFF state (①).

Thereafter, when the heating mode condition is satisfied, the fan 140 may start an operation prior to the heating device 130 as the processor 160 controls the fan 140 (②). At this time, the processor 160 may be implemented by additionally checking whether the previous operation was in the cooling mode, and controlling the fan 140 to operate prior to the heating device 130 only when the previous operation is in the cooling mode.

In addition, when the fan 140 is operated for a preset time, the processor 160 may check whether the humidity of the storage room 110 satisfies the preset humidity. Here, the preset time may be 1 hour, and the preset humidity may be 75%, but is not limited thereto.

If the humidity of the storage room 110 satisfies a predetermined humidity, the processor 160 may start the operation of the heating device 130 (③).

Referring to FIG. 7, first, the temperature of the storage room is sensed (S710). Then, the operation mode of the wine cellar is determined based on the temperature of the storage room and the set temperature for the storage room (S720). Specifically, when the temperature of the storage chamber is higher than the set temperature for the storage chamber, the operation mode of the wine cellar may be determined as the cooling mode. And when the temperature of the storage room is lower than the set temperature, the operating mode of the wine cellar may be determined as a heating mode.

In addition, the cooling device or the heating device may be selectively controlled based on the determined operation mode. Specifically, when the determined operation mode is the cooling mode, the cooling device may be controlled, and when the determined operation mode is the heating mode, the heating device may be controlled.

On the other hand, when the determined operation mode is the heating mode, the fan is controlled so that the outside air of the wine cellar flows into the interior of the storage room (S730). Specifically, the fan may be controlled so that the outside air of the wine cellar flows into the interior of the storage room for a predetermined time.

And the humidity in the storage room can be detected. If a plurality of humidity sensors are arranged at different locations in the storage room, a plurality of humidity can be sensed simultaneously using each of the plurality of sensors.

Then, the heating device is controlled to start supplying heated air during the operation of the fan (S740). Specifically, when the humidity of the storage compartment detected during the operation of the fan reaches a preset humidity, the heating device may be controlled to start supply of heated air.

Here, the preset humidity means a humidity sufficient to prevent dew condensation. In addition, the preset humidity may be set in consideration of the external temperature and the set temperature of the wine cellar. In this case, and an operation of sensing the external temperature of the wine cellar may be additionally performed. In addition, the preset humidity may be a fixed value such as 75%, but is not limited thereto.

More specifically, the heating device may be controlled to start supply of heated air when the sensed humidity reaches a preset humidity after the operation of the fan for a predetermined time. On the other hand, if the humidity detected after the operation of the fan for a predetermined time does not reach the predetermined humidity, the fan may be controlled to operate again for a predetermined time.

Or, after the operation of the fan for a predetermined time, calculate the average humidity of the humidity detected for a predetermined time, and when the calculated average humidity reaches a predetermined humidity, the heating device may be controlled to start supplying heated air Can.

Alternatively, when a plurality of humidity sensors are disposed in the storage room, the heating device may be controlled to start supply of heated air when all of the humidity detected by each of the plurality of humidity sensors reaches a predetermined humidity.

Therefore, the control method of the wine cellar of the present disclosure is to reduce the humidity of the storage compartment by controlling the fan to operate first when the operation mode of the wine cellar is determined as the heating mode, thereby condensing dew even when the temperature of the storage cell is higher than the external temperature It has an effect that can be prevented. The control method as shown in FIG. 7 may be executed on a wine cellar having the configuration of FIG. 1 or 2, or on a wine cellar having other configurations.

Further, the control method as described above may be implemented as at least one execution program for executing the control method as described above, and the execution program may be stored in a non-transitory readable medium.

The non-transitory readable medium means a medium that stores data semi-permanently and that can be read by a device, rather than a medium that stores data for a short time, such as registers, caches, and memory. Specifically, the various applications or programs described above may be stored and provided in a non-transitory readable medium such as a CD, DVD, hard disk, Blu-ray disk, USB, memory card, ROM, and the like.
