2 is a block diagram illustrating a temperature display device according to the present invention, wherein the temperature display device includes a sensor input unit 12 receiving a signal from a temperature sensor installed in a freezer compartment, a refrigerating compartment, and a multipurpose room, and a temperature setting switch within the refrigerator. A digital display unit 14 for outputting a high temperature inside the refrigerator (refrigerating room, a refrigerating room, and a multipurpose room) detected by the switch detecting unit 13 to receive a signal of the sensor, the sensor input unit 12, and a refrigerator door The warning light 15 which is turned on by the door switch being turned off at the time of opening, the audio output unit 16 which outputs the time required for food stored in the utility room to cool down to a set temperature by voice, and cold air in the utility room The display unit 14, the warning light 15, the audio output unit 16 and the cold air soil are inputted by receiving the signals from the cold air discharge unit 17 and the sensor input unit 12 and the switch detection unit 13 to discharge. It comprises a control unit 11 for controlling the outlet 17, the switch detection unit 13 is a door switch for outputting a specific signal when opening the refrigerator door, and installed in the multi-purpose room to keep the food A signal from a weight sensing switch for sensing and a food selection switch for selecting a type of food to be installed in an external panel of the refrigerator door to be stored in the utility room is input.

The weight sensing switch installed in the multipurpose room is a switch which is turned on when there is food stored in the multipurpose room, and the multipurpose room is the control unit 11 when the food is not stored in the multipurpose room (when the weight detection switch is turned off). Is maintained at the set temperature (about 10 ° C).

In the food selection switch installed on the outer panel of the refrigerator door, the types of foods that can be stored in the utility room such as beverages, fruits, meats, and vegetables are respectively displayed, and the control unit 11 displays each food displayed on the food selection switch. The set cooling temperature of each food which can maintain the freshness and taste of the best, and the experimental data of the time required for lowering the said food from the set temperature (about 10 degreeC) of the utility room to each set cooling temperature are memorize | stored.

Accordingly, when the user selects the type of food to be cooled by turning on the food selection switch after putting the food in the utility room, the control unit can receive the signal from the food selection switch to maintain the freshness and taste of the food at its best. By sensing the set cooling temperature to control the cold air discharge unit 17 of the multi-purpose room to cool the food in the multi-use room to the set cooling temperature, and outputs the time required to cool the food to the set temperature during the food cooling process by voice In case of opening door, it outputs warning message and lights warning lamp.

3 is a control flowchart illustrating a control method of a temperature display device according to an exemplary embodiment of the present invention.

When the control is started, the control unit 11 determines whether the food selection switch is turned on (S10), and if the food selection switch is turned on, after sensing the set cooling temperature of the food according to the turned on food selection switch (S11), the multipurpose room It is determined whether or not the food equilibrium is in a temperature equilibrium state in which the food is cooled to the same temperature as the set temperature (about 10 ℃) of the multipurpose room (S12).

Here, the temperature equilibrium state of the step S12 is after the food is put in the multipurpose room maintained at the set temperature (about 10 ℃), the temperature in the high temperature of the multipurpose room is increased by the temperature of the food and then back to the set temperature (about 10 ℃) The temperature equilibrium may be determined by receiving a signal from a temperature sensor that senses a temperature inside a multipurpose room.

When the temperature equilibrium is achieved, the control unit 11 estimates the time required for cooling the food to the set cooling temperature (S13), and outputs a message through the voice output unit 16 with the estimated time required in step S13. In step S14, the cold air discharge unit 17 is controlled to cool the food to the set cooling temperature in step S15.

Predicting the time required for cooling the food to the set cooling temperature in step S13 is made possible by using the experimental data stored in the controller.

Next, while cooling the food of the step S15 to the set cooling temperature to detect whether the refrigerator door is opened through the door switch (S16), and outputs a warning message through the voice output unit 16 when the refrigerator door is opened. (S17), the warning light is turned on (S18), and if the refrigerator door is not opened, the process proceeds to step S19.

In step S19, it is determined whether the estimated time required for output by voice has elapsed, and when the cooling time has elapsed, the internal temperature of the multipurpose room is sensed by the temperature sensor of the multipurpose room (S20), and the temperature and food setting of the multipurpose room are set. Comparing the cooling temperature (S21), if the internal temperature of the multipurpose room is higher than the set cooling temperature of the food, proceed to step S13 to predict the cooling time again, and if the high temperature of the multipurpose room is lower than the set cooling temperature of the food After outputting a voice message that the food has been cooled to the set cooling temperature (S22), it is determined whether the food is being stored in the multipurpose room through a weight sensing switch installed in the multipurpose room (S23).

When the food is being stored in step S23, the cold air discharge unit 17 is controlled to maintain the inside temperature of the multipurpose room at the set cooling temperature of the food (S24), and when the food is not being stored, the cold air discharge unit 17 is stored. By controlling, the multipurpose room is maintained at a set temperature (about 10 ° C) (S25).

As a result, the freshness and taste of the food stored in the multipurpose room can be maintained at the best, and the user can predict the time required for cooling the food to the set cooling temperature, and a warning message is output when the refrigerator door is opened. This can prevent the user from frequently opening the refrigerator door.

4 is a control flowchart illustrating a method of controlling a temperature display device according to another embodiment of the present invention, which predicts a time required for cooling a food stored in a multipurpose room to a set cooling temperature, and estimates the estimated time required for the food. It outputs a voice periodically until it cools to this set cooling temperature, outputs a warning message by voice at the time of opening a refrigerator door, and activates a warning light.

Accordingly, the control unit 11 determines whether the food selection switch is turned on (S30), and if the food selection switch is turned on, after sensing the set cooling temperature of the food according to the turned on food selection switch (S31), it is placed in the utility room. It is determined whether a temperature equilibrium state is achieved in which the food is cooled to an internal temperature (about 10 ° C.) in the utility room (S32).

If it is determined in step S32 that the temperature equilibrium has been achieved, the controller 11 estimates the time required to cool the food to the set cooling temperature (S33), and calculates the estimated time required in step S33 to the audio output unit 16. By outputting a message through (S34), and controlling the cold air discharge unit 17 to cool the food to the set cooling temperature (S35).

Next, in step S35, while the food is cooled to the set cooling temperature, it is detected whether the refrigerator door is opened through the door switch (S36), and when the refrigerator door is opened, a warning message is output through the voice output unit 16 ( S37), the warning light is turned on (S38), and if the refrigerator door is not opened, the process proceeds to step S39.

In step S39, a predetermined time (about 10 minutes) is counted (S39), and the inside temperature of the multipurpose room is sensed by the inside temperature sensor of the multipurpose room (S40), and the inside temperature of the multipurpose room is compared with the set cooling temperature of the food ( S41), if the internal temperature of the multipurpose room is higher than the set cooling temperature of the food, the process proceeds to step S33 to estimate the cooling time again, and if the high internal temperature of the utility room is lower than the set cooling temperature of the food, the food is returned to the set cooling temperature. The message that the cooling is output as a voice (S42).

Subsequently, it is determined whether the food is being stored in the multi-use room through the weight sensing switch installed in the multi-use room (S43). When it is determined that the food is not being stored (S44) and the food is not being stored, the cold air discharge unit 17 is controlled to maintain the multipurpose chamber at the set temperature (about 10 ° C) (S45).

As a result, the freshness and taste of the food stored in the multipurpose room can be maintained at the best, and the time required for cooling until the food is cooled to the set cooling temperature can be output periodically (every 10 minute intervals). It is possible to prevent the user from opening the refrigerator door frequently by outputting a warning message when the refrigerator door is opened.

According to the temperature display device and the control method of the refrigerator having a multi-use room according to the present invention configured as described above, the food at a cooling temperature that can maintain the freshness and taste of each food, such as beverages, fruits, meat, vegetables, etc. It is easy to cool, and because the user can predict the time required to cool the food to the set cooling temperature, it is possible to provide convenience to the user, and to increase the temperature in the high temperature according to the opening of the door when opening the refrigerator door The alarm prevents the user from frequently opening the refrigerator door.
