Referring to
The storage compartment 50 forms an accommodating space to store food in a main body 15. The storage compartment 50 may be provided as single or plural compartments in the main body 15, as necessary. If the storage compartment 50 is plurally provided, each of the compartments 50 is divided by an insulating material. The compartments 50 may operate uniformly as a whole, or perform fermentation and refrigeration functions independently.
The heating/cooling part 60 is provided as at least one of a heating part 61 and a cooling part 65 to ferment food in the storage compartment 50. For example, if room temperature is lower than the fermentation temperature, only the heating part 61 may be provided. If the room temperature is higher than the fermentation temperature, only the cooling part 65 may be provided. Alternatively, both the heating part 61 and the cooling part 64 may be provided to ferment and refrigerate food. Here, the heating part 61 may be provided as an electric resistance heating element, but not limited thereto. The cooling part 65 may be comprised of a cooling cycle having a compressor. At this time, an outer wall of the respective storage compartments 50 is surrounded by a refrigerant pipe and a heater.
a through 4c illustrate various embodiments of the input part 70 and the display part 80 in the kimchi refrigerator with a manual fermentation method.
Referring to
The fermentation button 71 is selected to ferment food stored in the fermentation apparatus 10. If the fermentation button 71 is selected, the heating/cooling part 60 operates by a controller 30 (to be described later) to apply a fermentation temperature to the storage compartment 50.
The memory button 75 is selected to memorize when the food reaches a predetermined fermentation level, which a user wants to memorize. If the memory button 75 is selected, the controller 30 (to be described later) memorizes the fermentation level of the food sensed by the sensor 20 (to be described later). Here, the number of the memory button 75 may be properly provided according to the number of custom fermentation levels which a user wants to memorize.
Here, even if the custom fermentation level is stored by a user through a first memory button 75a, a new fermentation level may be memorized by selecting the first memory button 75a next time.
Meanwhile, the number of the memory button 75 may not conform to that of storable custom fermentation levels. As shown in
As shown in
If the custom fermentation level is stored through the memory button 75, a memory display 79 may be provided to display storage of the custom fermentation level by the controller 30 (to be described later). As shown in
The refrigeration button 73 enables a user to manually control the heating/cooling part 60 through the controller 30 (to be described later) to complete the fermentation mode and convert into the refrigeration mode. If the memory button 75 is selected, the controller 30 may control the heating/cooling part 60 to complete the fermentation of the food and at the same time convert into the refrigeration mode automatically, without using an additional refrigeration button 73.
If fermenting the same kind of food into the memorized custom fermentation level after memorizing the foregoing custom fermentation level, a user may select the memory button 75 corresponding to the desired custom fermentation level. Then, the controller 30 controls the heating/cooling part 60 to ferment the food into the memorized fermentation level, thereby repeatedly providing the food at the desired fermentation level without difficulty. After completing the fermentation, the memory display 79 displays the completion of fermentation to make a user manually convert, or to make automatically complete fermentation and convert into the refrigeration mode.
The sensor 20 is provided in a predetermined place in the storage compartment 50 to sense the fermentation level of the food stored in the storage compartment 50. Here, the sensor 20 may be provided anywhere to sense the fermentation level of the food. For example, if an extra container is disposed in the storage compartment 50 to accommodate food, the sensor 20 may be provided therein.
If the memory button 75 is selected, the sensor 20 operates by the controller 30 to sense the fermentation level of the food in the storage compartment 50, or starts sensing as soon as the food is fermented, to transmit information on the fermentation level to the controller 30.
The sensor 20 may be provided as a gas sensor to sense the concentration of a gas generated from the food in the storage compartment 50, but not limited thereto.
Meanwhile, the sensor 20 may be provided as a gas sensor to sense the generation of the gas when food generates a predetermined gas. For example, as some foods generate the predetermined gas, or increase the concentration of the predetermined gas drastically at a predetermined fermentation level, such characteristics may be sensed by the sensor 20 at the fermentation level to be memorized. The sensor 20 may be provided as a pH sensor to sense pH (acidity) generated from fermented food.
If a user selects the memory button 75, the controller 30 stores the fermentation level of the food sensed by the sensor 20, the fermentation level when selecting the memory button 75, and controls the heating/cooling part 60 to make the fermentation apparatus 10 operate in the fermentation and refrigeration modes. If the memory button 75 is selected, the controller 30 automatically converts from the fermentation mode to the refrigerating mode, or converts manually through input of the refrigeration button 73 additionally provided in the input part 70. Alternatively, fermentation of the food may be continued, and a new fermentation level is stored through reselection of the memory button 75.
If selecting the stored custom fermentation level to custom-ferment the food, i.e. if a user stores the custom fermentation level and restores the same kind of food in the fermentation apparatus 10 and selects the memory button 75 corresponding to the custom fermentation level, then the heating/cooling part 60 is controlled to proceed with fermentation of the food, and at the same time, the sensor 20 is controlled to senses the fermentation level of the food.
Here, the fermentation temperature may be selected by a user, or the controller 30.
At this time, the controller 30 compares a fermentation value according to the fermentation level sensed from the sensor 20 with a stored custom fermentation value to determine a current fermentation level. If determined that the sensed fermentation level does not reach the stored custom fermentation level, the fermentation mode is maintained. If determined that the sensed fermentation level reaches the stored custom fermentation level, the heating part 61 and the cooling part 65 are controlled to complete fermentation and convert into the refrigeration mode. The input part 70 may be provided with the refrigeration button 73 to manually convert from the fermentation mode into the refrigeration mode.
An alarm 90 may be further provided to notify a user that the food reaches the custom fermentation level by the controller 30. Here, the alarming method of the alarm 90 is not limited. For example, the alarm 90 may be provided as a visual alarm, which turns on and off at predetermined intervals, an auditory alarm to generate predetermined alarming sound or both of which may be used.
A display part 80 may be further provided to display the determined fermentation level. At this time, the controller 30 controls the display part 80 to display the determined information thereon to be acknowledged by a user.
The fermentation apparatus 10 according to the first embodiment of the present invention memorizes a desired fermentation level according to users without difficulty, thereby providing food at a uniform fermentation level through the custom fermentation after setting an initial custom fermentation level.
As shown in
The memory 40 is provided in a predetermined place in a main body 10. The sensor 20 senses a fermentation level of food and stores information on the fermentation level to the memory 40 through the controller 30 (to be described later). Here, not all the fermentation values sensed by the sensor 20 are stored in the memory 40, and only fermentation values which are sensed when selecting a memory button 75, may be stored in the memory 40.
The information stored in the memory 40 varies according to types of the foregoing sensor 20. For example, if the sensor 20 is provided as a gas sensor to sense the concentration of a gas in a storage compartment 50, the memory 40 is stored with the fermentation value corresponding to the gas concentration. If the sensor 20 is provided as a gas sensor to sense a predetermined gas in the storage compartment 50, the memory 40 is stored with a sensing signal when the predetermined gas is generated in the storage compartment 50. If the sensor 20 is provided as a pH sensor, the memory 40 is stored with the fermentation value corresponding a pH value at the selected fermentation level in the storage compartment 50.
The memory 40 may be stored with fermentation values at each fermentation level of fermented food frequently consumed such as kimchi, as well as the fermentation value at a custom fermentation level, in advance. For example, a fermentation value may be stored in the memory 40 in advance, which corresponds to a pH value of gas concentration at each fermentation level of dongchimi, a kind of kimchi, as shown in
With this configuration, a custom fermentation method of the fermentation apparatus available for a custom fermentation will be described with reference to
A user stores food in the storage compartment 50 of the fermentation apparatus 10 to ferment it at operation S110, and the fermentation apparatus 10 starts fermenting the food by selecting the fermentation button 71 provided in the input part 70 at operation S111. At this time, a user may set the custom fermentation level or not at operation S112. If a user may not set the custom fermentation level, the fermentation apparatus 10 keeps fermenting the food until receiving an extra command from a user at operation S117. If an automatic fermentation function is selected, the food may be refrigerated after being fermented corresponding to a set operation condition.
After starting fermenting the food, the controller 30 controls the sensor 20 to sense the fermentation level of the food in the storage compartment 50 at operation S113. Here, a user may select the memory button 75 to make the sensor 20 start sensing the fermentation level of the food.
Meanwhile, a user may check the fermentation level of the food while it is fermented. For example, a user may taste, smell or check it through the display part 80 displaying the fermentation level which is determined by the controller 30 after the sensor 20 senses.
If the food reaches the fermentation level which a user wants to memorize, a user may select the memory button 75 to memorize it at operation S115. If the memory button 75 is selected, the controller 30 stores the sensed fermentation level by the sensor 20 as the custom fermentation level at operation S116, which is sensed when selecting the memory button 75. If an extra memory 40 is provided, the controller 30 stores the fermentation value in the memory 40.
Also, the controller 30 controls the heating/cooling part 60 to make the fermentation apparatus 10 converted into the refrigeration mode after completing fermentation of the food through input of the refrigeration button 73 or automatically, at operation S118. For example, if a user wants to set the custom fermentation level into various levels or change the stored custom fermentation level, fermentation may be continued at operation S117.
If a user selects the stored custom fermentation level, the controller 30 controls the heating/cooling part 60 to make the storage compartment 50 heated or cooled for fermentation of the food therein at operation S122. At the same time, the controller 30 controls the sensor 20 to sense the fermentation level of the food at operation S123. The controller 30 receives the information on the fermentation level of the food sensed by the sensor 20 and compares it with the selected custom fermentation value to determine the fermentation level of the food. The display part 80 may display the determined fermentation level of the food.
If sensed by the sensor 20 that the fermentation value of the food reaches the custom fermentation value, the controller 30 controls the heating/cooling part 60 to stop fermenting the food at operation S125. If not reaching the custom fermentation value, fermentation of the food is continued. The completion of fermenting food may be noted through an alarm 90 visually or auditorily.
After completing fermentation of the food, the controller 30 controls the heating/cooling part 60 to convert into the refrigeration mode through input of the refrigeration button 73 or automatically.
Although a few embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
