The present invention relates to a high temperature control refrigerator and a high temperature control method, and more particularly, heat generated in a magnetic field when the internal temperature is in normal operation by using a paramagnetic salt of an electromagnet that generates heat in a magnetic field and rapidly cools when the magnetic field is removed. And a refrigerator for controlling the temperature by rapidly absorbing heat generated by removing the magnetic field during overload, and a method for controlling the internal temperature using the refrigerator.

1 is a view illustrating a configuration of a conventional general refrigerator. As shown in FIG. 1, the refrigerator is divided into a refrigerator compartment 2 and a freezer compartment 4. A heat exchange chamber 6 is provided at the rear of the freezing chamber 4, and an evaporator 8 and a blowing fan 9 are provided therein. The cold air generated by the contact with the evaporator 8 is supplied to the freezing chamber 4 and the refrigerating chamber 2 through the blowing fan 9.

In such a refrigerator, controlling the temperature inside the refrigerator is based on the freezer compartment 4 or the refrigerator compartment 2. That is, while operating the freezing cycle according to the temperature of the freezer compartment 4, the cold air is generated and the blower fan 9 is driven to supply cold air (based on the freezer compartment), and the blower fan 9 is operated in accordance with the temperature of the refrigerating compartment 2. It is also used to supply cold air (refrigerator).

According to the method of supplying cold air based on the refrigerating compartment 2, the temperature inside the refrigerating compartment 2 is sensed, and the detected temperature is compared with a preset reference temperature. And simultaneously driving the blower fan 9 to supply cold air therein.

The following problems are pointed out in the control method of controlling the supply of cold air on the basis of such a refrigerator compartment 2. When the external temperature of the refrigerator is low (for example, 10 ° C. or less), the temperature of the refrigerating chamber 2 may be maintained at an appropriate level even if the driving time of the refrigeration cycle is not long. Therefore, in such a case, even if the operation time of the refrigerator is short, the reference temperature of the refrigerating compartment 2 can be sufficiently satisfied, but when the overload or the door is opened and closed, the internal temperature rises, so that the compressor is used for cooling to offset the temperature. C) and a rapid freezing by the blowing fan (9).

By the way, the conventional compressor only on and off and the operation of the blower fan 9, because it takes a considerable time to reach a sufficient cooling has a disadvantage that the food stored in the interior is not properly maintained.

The present invention has been conceived to overcome the disadvantages of the prior art described above, when the internal temperature of the refrigerator is low during normal operation, the heat generated in the magnetic field is treated, and the heat generated during the overload or door opening and closing rapidly rapidly It is an object of the present invention to provide a refrigerator for maintaining the temperature at a constant temperature and a method for controlling the internal temperature using the same.

The present invention comprises a refrigerator including a control unit for controlling an electromagnet installed in the cold air circulation path of the refrigerator and an electromagnet unit for generating and extinguishing a magnetic field, in order to achieve the above-mentioned technical problem, The present invention provides a method of controlling the internal temperature by rapidly absorbing heat by treating heat generated in the intestine and removing a magnetic field in case of overload.

To this end, the high temperature controlled refrigerator includes a temperature sensor for detecting a high temperature, a controller for detecting a high temperature and comparing the detected temperature with a set temperature to turn the electromagnet on and off, and generating or dissipating a magnetic field to generate heat or rapidly absorb heat. An electromagnet portion for maintaining a high internal temperature at a constant temperature, and an electromagnet power supply for supplying power to the electromagnet portion to turn the electromagnet portion on and off.

In the high temperature control method implemented by the refrigerator having the above configuration, the refrigerator operating in the normal mode according to the control temperature set in the control unit, and the temperature detected by the temperature sensor in the normal operation mode to the off-point temperature Checking whether the temperature has been reached; turning off the electromagnet if the detection temperature is the off-point temperature; turning on the electromagnet if the detection temperature is not the off-point temperature; and turning on the temperature after the electromagnet is turned on. Checking whether the detection temperature by the detection sensor is more than a specific temperature than the on point, and if the detection temperature is above a specific temperature, the step of turning off the electromagnet is implemented.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached invention.

2 is a cross-sectional view of a refrigerator provided with an electromagnet unit for controlling a high internal temperature according to the present invention, and includes a freezing compartment 21 and a refrigerating compartment 22 divided into a refrigerator body 20 forming an exterior of the refrigerator. In the rear of the freezing chamber 21, a cooler 26 that generates cold air and a blower 23 for blowing cold air from the cooler 26 into the inside are provided, and the cold air is blown out from the blower 23 into the high air. The vent 24 is formed. Here, a temperature sensor 28 for detecting a high temperature inside is installed at one side of the freezing chamber 21. Of course, it is also applicable to configure the temperature sensor 28 in the refrigerating chamber 22 to sense the temperature. This is because it is also possible to perform cooling control based on the temperature of the refrigerating chamber 22.

In the diaphragm cutting portion 27 of the freezing chamber 21 and the refrigerating chamber 22, a cold air return path 25 is formed so that cold air that has cooled the freezing chamber 21 and the refrigerating chamber 22 can be returned. The electromagnet portion 30 for generating a magnetic field is installed in the furnace 25. The electromagnet unit 30 is connected to the control unit 400 which performs overall control of the refrigerator to perform a cooling operation.

3 is a view showing the electromagnet portion 30 installed in the diaphragm cutting portion 27. That is, in FIG. 2, the diaphragm cutting part 27 is a cross-sectional view of the electromagnet part 30 cut along the A-A 'axis, and the electromagnet part 30 is positioned in the middle of the cold air return path 25, which is a space for cold air return. Is installed. And the support 31 for supporting the electromagnet portion 30 is formed above and below the electromagnet portion 30, both sides of the electromagnet portion 30 is formed with an insulator 32 for insulating the magnetic field. Therefore, two spaces are formed with the electromagnet part 30 interposed therebetween, and the upper side is a freezer compartment circulation path 33 for allowing cold air circulated from the freezing compartment 21 to be returned to the cooler 26, and the lower side is a refrigerator compartment 22. It becomes the refrigerator compartment circulation path 34 which causes the cold air circulated from the return to the cooler 26.

The electromagnet unit 30 is connected to the control unit 400 for controlling the function of the refrigerator to perform the high temperature control of the present invention, a circuit block diagram showing this is shown in FIG. That is, Figure 4 is a block diagram for performing a function for controlling the internal temperature in accordance with the present invention, the control unit 400 for performing the refrigerator function, the temperature sensor 410 for detecting the internal temperature and the electromagnet unit 30 Electromagnet power supply unit 420 for supplying power), a compressor driving unit 430 for driving a compressor (not shown), and a display panel control unit 440 for displaying a refrigerator function or an operation key. Referring to the functions and roles of the components of the block diagram having such a structure as follows.

The control unit 400 includes a microcomputer for performing a function required in the refrigerator and is connected to other components mentioned above to transmit a command or receive information and process the same. That is, when the temperature inside the refrigerator is raised or lowered by the temperature sensor 28 provided in the refrigerator, it is possible to maintain a constant temperature by generating or removing a magnetic field in the electromagnet unit 30 compared to the temperature set in the controller 400. Done.

Therefore, when the temperature sensor 28 detects a high internal temperature and transmits temperature information, the control unit 400 receives the signal and transmits a signal to the compressor driving unit 430 or the electromagnet power supply unit 420 so that the compressor is turned on / off. Alternatively, the electromagnet unit 30 may generate or destroy the magnetic field.

The temperature sensor 28 detects the high temperature inside and transmits the same to the controller 400. Therefore, when the door is opened or closed, the food inside the hot temperature is changed, so the temperature change information is detected and transmitted to the control unit 400.

The electromagnet power supply unit 420 performs a function of supplying power to the electromagnet unit 30 generating a magnetic field according to the command of the controller 400. In general, the electromagnet forms a magnetic field by winding a coil around an iron core and flowing electricity to the coil. In contrast, in the present invention, when the magnetic field is applied, heat is released and when the temperature is released from the magnetic field, the temperature is lowered. 'Using the property.

In other words, self-freezing is generated by using a gadolinium alloy (Gd 5 (Si 2 Ge 2)), which is a paramagnetic salt as an iron core. This gadolinium alloy is applicable because of its excellent self-freezing effect even at room temperature. Magnetic refrigeration is already known and can be understood by those skilled in the art, and thus a detailed description thereof will be omitted.

Therefore, when power is supplied to the electromagnet unit 30 by the electromagnet power supply unit 420, a magnetic field is generated to generate heat, thereby increasing the internal temperature. Otherwise, if the electromagnet unit 30 is not supplied with power, the magnetic field is extinguished. As a result of rapid endotherm, the internal temperature drops. That is, after the temperature of the cold air flowing through the freezer compartment circulation path 33 or the refrigerating compartment circulation path 34 passes through the electromagnet part 30, the temperature rises or falls, and then the cooler 26 passes back to the freezer compartment 21 or the refrigerator compartment 22. It will be blown.

The compressor driving unit 430 compresses the refrigerant by turning on / off the compressor according to the command of the controller 400.

The display panel manipulation unit 440 is usually provided at the front of the refrigerator and includes a button unit for controlling the function of the refrigerator and a display unit for allowing the user to check the function. Examples of these functions include a power button for powering, a lock / unlock button for locking or unlocking the selected function, and an ice making function.

The process of controlling the high internal temperature is implemented using the configuration of FIGS. 2 to 4 described above, and a flowchart showing such a process is shown in FIG. 5. In other words, this is a process of controlling the temperature by processing the heat generated in the magnetic field during the normal operation of the high temperature and rapidly absorbing the heat generated by the magnetic field removal during the overload. The high temperature control process is as follows.

The refrigerator is in the normal operation mode until the user opens the door or generates a load. In this normal operation mode, the control unit 400 turns the compressor on and off according to a set cycle to maintain the internal temperature at a constant state (step S500).

In the normal operation mode, the control unit 400 receives the detected temperature information from the temperature sensor 28 and checks whether the detected temperature reaches the off point temperature (step S510). That is, it is confirmed whether the internal temperature is cooled to a predetermined temperature or more.

If the detected temperature does not reach the off point temperature as a result of checking the off point temperature, the controller 400 maintains the electromagnet in the off state (step S511).

On the contrary, if the detected temperature reaches the off point temperature, the controller 400 supplies power to the electromagnet unit 30 to turn on the electromagnet (step S520). Therefore, when the electromagnet is turned on, a magnetic field is generated and the heating temperature rises.

After the internal temperature rises, the temperature sensor 28 detects the internal temperature and transmits the temperature information to the controller 400 again. The control unit 400 checks whether the detected temperature is above a specific temperature from the ON point from the transmitted temperature information (step S530). In other words, if the internal temperature rises due to the magnetic field of the electromagnet, the temperature rise is about 5 degrees higher than the ON point, the driving point of the compressor.

As a result of checking the specific temperature abnormality, if the detected temperature is higher than the specific temperature, the controller 400 turns off the electromagnet (step S540).

In other words, by stopping the power supply to the electromagnet portion 30, the magnetic field is extinguished, thereby rapidly cooling the temperature in the refrigerator. Of course, if the internal temperature does not reach a certain temperature, the electromagnet is kept on.

As mentioned above, the present invention has been described in detail with reference to the accompanying embodiments and drawings, but the present invention is not limited to the specific embodiments, and those skilled in the art or acquiring general knowledge are provided with the contents of the present invention. It should be understood that numerous variations and modifications can be made without departing from the scope of the invention. Therefore, the protection scope of the present invention will be preferred based on the appended claims.

According to the present invention, when the internal temperature is low, the heat generated in the magnetic field is treated, and when the overload is overheated, the magnetic field is rapidly absorbed to maintain the internal temperature at a constant state.
