Description

System for rice box combined with Kimchi refrigerator}

The present invention relates to a kimchi refrigerator combined rice container system, and more specifically, the outer circumferential wall is filled with a heat insulating material, the center is partitioned to store kimchi in one storage compartment of the main body having a pair of storage compartment, grain (rice) in the other storage compartment Kimchi refrigerator combined rice pail system to store each).

In general, Kimchi refrigerator fermented and aged soaked kimchi mechanically to suit the taste of the user, this aged kimchi is a device to maintain a long-lasting taste by storing for a long time, the kimchi refrigerator is filled with kimchi Fermentation aging by heating the storage room with a heater, and when this aging is completed, the temperature of the storage room is kept at a low temperature in a refrigerant cycle to suppress fermentation and ripening of kimchi so that the user can eat and store the desired kimchi taste for a long time. It is.

As such, the kimchi refrigerator may exert an excellent effect in the case of kimjang which is stored for a long time, but in the summer season when the kimchi is soaked in a small amount frequently, there is a problem in that the utilization efficiency of the storage room is reduced.

Therefore, in order to increase the use efficiency of the kimchi refrigerator in the summer at home, it is often used while storing vegetables and grains (rice) in the storage room in addition to the original function of the kimchi refrigerator.

However, when storing vegetables and grains (rice) in the kimchi refrigerator as described above, since the grains (rice) are simply stored at a relatively low temperature, is there a case where grains (rice) containing a predetermined moisture are frozen? When the quality of the grains and the rice taste are impaired, in order to take out the stored grains (rice), in addition to the inconvenience of having to open and close the upper door one by one, the stored grains (rice) due to the temperature deviation caused by opening and closing the door. There is a problem that the deterioration occurs in the case of the winter season when kimchi is a lot even had a problem that can not be used.

Therefore, since long time ago, general households have set up a separate rice canister to store and store rice, but it is used to store and store rice, but most of them do not have a device that can control temperature and humidity, which affects the temperature and humidity of the surrounding environment. In fact, the situation has not been able to control.

Therefore, the rice should be stored under an environment having an appropriate temperature and humidity, so that no deterioration occurs and rice worms can be stored for a long time and rice can be maintained.

That is why it is important to maintain good temperature and humidity in rice storage and storage. In other words, the optimal preservation environment of the rice is a temperature of 10 to 15 ℃, the conditions that can maintain the moisture of the rice at about 13 to 15% at a humidity of 70 to 75%.

So, according to Korean Patent Application Laid-Open No. 1999-003920 (name: cold-cold rice container device) recently, unlike a rice barrel which is not equipped with general temperature and humidity control, in order to maintain the optimal rice preservation environment, A rice holding container; Measuring means for measuring a predetermined amount of rice stored in the rice storage container; Cooling dehumidification means for cooling and dehumidifying the air of the rice storage container; By circulating means for circulating the cold air dehumidified by the cooling dehumidifying means between the cooling dehumidifying means and the rice storage means container, by cooling the air of the rice storage container containing the rice with the cooling means, dehumidification control by the dehumidifying means, There is a thing to store and store the rice in the cooling dry air is moisture is removed, the case of the rice barrel is only one use for storing and storing only simple rice, there is a problem that the efficiency in use is lowered.

In addition, according to Korean Patent Laid-Open Publication No. 1997-074812 (name: rice tank for controlling insect repellent and micro-conditioning with a cooling device), rice storage container for receiving and storing rice; A cooling device and a cold air supply device for generating and supplying cold air to the rice storage container; A cold air discharge pipe for discharging cold air to the outside in the rice storage space; A moisture content controller for controlling moisture in a predetermined amount of moisture and stored rice in the rice storage container; A water detection sensor for detecting a water content in the rice storage container; A grain temperature sensor for detecting a temperature change of rice stored in a rice storage container; The rice storage container is configured as a control unit for controlling the moisture and the grain temperature of the rice, but in the case of the rice barrel is configured to store moisture while supplying water to the rice by providing a moisture regulator in addition to the cooling device for controlling the temperature of the stored rice In addition to the complexity of the storage device configuration, this also has limitations for use in applications other than rice barrels.

As described above, conventionally, only one function of the kimchi refrigerator or the rice bucket is performed, and in order to store and store kimchi and rice in a general home, the economic burden of having two devices, as well as the amount of soaking kimchi recently In the era of newlyweds or nuclear families, which are small and consume less rice, having the two devices each has a problem that the efficiency is greatly reduced in terms of use as well as economic loss.

Thus, according to the Republic of Korea Utility Model Application No. 1999-029557 (name: Kimchi refrigerator equipped with a rice container), the main body is provided with an opening and closing the lower side is formed in the inlet, outlet, the removable container is fitted; An intermediate wall partitioning the inside of the main body into a machine room and a storage room, the intermediate wall being inclined downward toward the front side and having an opening sealed by a cover member; A funnel-shaped discharge port provided below the opening so as to face the upper side of the container and having a blocking member for discharging and blocking contents; It is installed on the lower outside of the main body corresponding to the discharge port and configured to selectively operate the blocking member, so that it is used to store and store kimchi and rice in one storage room, but in the case of the kimchi refrigerator When the smell of kimchi matured inside is cut into the stored rice, the rice is stored and stored at a temperature for storing the kimchi, and thus the rice is stored at a relatively low temperature. I had a problem that was degraded.

Accordingly, an object of the present invention is to use a kimchi refrigerator to cool the air with a refrigerant cycle to ripen and store kimchi in one side of the main body provided with a pair of storage compartments, and the other storage compartment is an optimal storage environment with low temperature cold of the one storage compartment. By using it as a rice container for storing and storing rice while maintaining, it is possible to use a Kimchi refrigerator and a rice container as a single device.

According to the present invention configured as described above, first, the storage to be stored in each of the storage compartment 200 and the storage compartment 250 provided in the main body 300 is opened and put in the door 201, in which case the storage compartment 200 is provided. Kimchi is put, and the other storage compartment 250 is put rice.

As described above, in the state in which the kimchi and the rice, which are stored in the storage compartment 200 and the other storage compartment 250, are respectively stored, the user operates the operation panel unit 301 of the control unit 350 provided in the front of the main body 300. When the maturation and storage conditions are input for the kimchi placed in one storage compartment 200, the microcomputer 307 of the controller 350 inputs the program input to the operation panel unit 301 with a preset program. The state is displayed on the display unit 308 (step 401).

Subsequently, the microcomputer 307 determines whether or not to ripen kimchi according to an input condition (step 402). In this case, the heating unit 213 is heated by controlling the heater unit 309 under the ripening condition.

At this time, the aging conditions are aged while heating the storage compartment 200 to a aging temperature (21 ~ 27 ℃) by a predetermined program. Of course, depending on the conditions to be aged may be aged at a higher or lower temperature than the temperature conditions, the ripening time is also ripened to a predetermined time according to the temperature conditions (step 403).

As described above, the microcomputer 307 determines whether the aging is completed (step 504). If the aging is not completed, the microcomputer 307 drives the heater 213 until the aging is completed.

However, when the aging is completed, the microcomputer 307 controls the heater 309 to turn off the heater 213, and controls the compressor driver 310 to store the mature kimchi to the compressor 215. The refrigerant is compressed, and the compressed refrigerant flows into the evaporator 211 through the condenser 212 to cool the storage compartment 200. At this time, the cooling of the storage compartment 200 is a storage condition in which an internal temperature is preset. That is, while cooling to within the storage temperature (-3 ~ 3 ℃) to store the aged kimchi (step 405).

Subsequently, the microcomputer 307 controls the first temperature sensor unit 302 to sense the current storage temperature of the current storage compartment 200 by using the temperature sensor 214 (step 406), and the stored storage temperature is set and stored. It is determined whether it is within the temperature (-3 to 3 ° C.) range (step 407).

At this time, if the detected storage temperature is not within the set storage temperature range, that is, if the detected temperature is higher than the set storage temperature, the compressor 215 is continuously driven to cool one storage compartment 200, while the detected temperature Is in the storage temperature range (-3 to 3 ° C.), the microcomputer 307 determines that the one side storage chamber 200 maintains the storage temperature, and the compressor 215 being driven through the compressor driving unit 310. ) To stop the cooling of the one storage compartment 200 to store the kimchi (step 408).

Meanwhile, in the state in which the kimchi is cooled and stored in the storage compartment 200 at a storage temperature, the user stores the grain (rice) put in the other storage compartment 250 of the body 300 without deterioration. The operation panel 301 of the control unit 350 provided on the front surface of the 300 is operated to input temperature, humidity, and moisture, which are storage conditions (step 410).

When the storage condition is input, the microcomputer 307 controls the damper part 311 to open the damper 257 provided on the heat insulating material partitioned between the one storage compartment 200 and the other storage compartment 250. The cold air of one storage compartment 200 is supplied to the cold air storage unit 260 through the cold air passage 252 to cool the other storage compartment 250.

As described above, the other storage compartment 250 is cooled and the microcomputer 307 detects whether the internal temperature, the internal humidity, and the water of the rice in the other storage compartment 250 are in the storage condition (step 412).

That is, the microcomputer 307 controls the second temperature sensor unit 303 to cool through the temperature sensor 253 and sense the internal temperature of the other storage chamber 250, and the detected temperature is the storage temperature of the rice ( 15 ° C.) or less (step 413).

At this time, if the detected temperature is not less than the storage temperature of the rice (15 ℃) or less, the microcomputer 307 is determined as a condition that can cause deterioration of rice or rice worms to lower the internal temperature of the other storage compartment 250 In order to continuously open the damper 257, the damper 257 is supplied to the cold air storage chamber 260 with cold at a relatively low temperature (3 ° C.) and cooled.

On the other hand, if the internal temperature is less than the storage temperature (15 ℃) of the rice, the microcomputer 307 determines that the rice storage temperature is suitable, and then controls the humidity sensor unit 304 to the other side through the humidity sensor 254 The internal humidity of the storage compartment 250 is sensed to determine whether the detected humidity is less than or equal to a set humidity (70%) suitable for storing rice (step 414).

At this time, if the detected humidity in the micom 307 is not less than the humidity (70%) suitable for the storage of rice, the microcomputer 307 determines that the internal humidity is high to continue to open the damper 257 to the By cooling the other storage compartment 250, the internal humidity is stored while the internal humidity is not increased (step 414).

However, if the detected humidity is less than the humidity (70%) suitable for the storage of the rice, the microcomputer 307 determines that the humidity is suitable for storage, it is to detect the moisture state of the rice being stored, that is, The microcomputer 307 controls the moisture sensor unit 305 to detect the moisture state of the rice stored by the moisture sensor 255, and determines whether the detected moisture is more than the appropriate moisture (14%) ( Step 415).

In this case, if the detected moisture is not more than 15% of the appropriate moisture, the microcomputer 307 continuously opens the damper 260 to cool the other storage chamber 250, thereby drying the moisture. Will be saved while avoiding.

However, if the sensed moisture is more than the appropriate moisture (14%), the microcomputer 307 determines that it is an appropriate condition for storing rice, and controls the damper unit 311 to close the damper 257 to close the one storage compartment 200. By blocking the inflow of the cold air storage unit 260 from being stored so as not to cool any more (step 416).

As described above, the microcomputer 307 determines whether the rice discharge signal is input through the operation panel unit 301 while maintaining the other storage chamber 250 to be suitable for the rice storage condition (step 417). If the discharge signal is not input, the storage state is maintained. On the other hand, if the rice discharge signal is input, the microcomputer 307 controls the metering unit 312 and is provided at the outlet 251 of the other storage compartment 250. The amount corresponding to the input rice discharge signal by moving the solenoid 271 of 270 to the manpower and the repulsive force for a predetermined time while opening and closing the metering tool 272 provided on the weighing plate 273 linked with it left and right. As much rice is discharged to the storage receiver 320 (step 418).

When the discharge of the rice is completed as described above, the microcomputer 307 controls the weight sensor unit 306 to detect the current residual amount through the weight sensor 256 mounted on the outlet 251 side of the other storage compartment 250. Then, the detected residual amount is displayed on the display panel of the control unit 350 located in front of the main body 300 through the display unit 308 to store the rice while the user confirms the remaining amount of rice. It will be stored (step 420).

As described above, in the present invention, the outer wall is filled with a heat insulating material, and the center is partitioned with a heat insulating material to configure a pair of storage chambers, one side of the pair of storage chambers is used as a kimchi refrigerator for aging and storing kimchi in a refrigerant cycle. The other storage compartment of the pair of storage compartments can be used as a rice container for storing grain (rice) to be stored at a relatively low temperature cold of the one storage compartment, so that a single device can be used for long-term storage of different storage items under different storage conditions. Therefore, according to the increase in the value of the use value and use, it is possible to provide the effect of reducing the economic waste of having to purchase different devices.
