ャル温度（−３℃）に維持するようになっている。In general, methods for thawing frozen foods include natural thawing by leaving frozen foods on the table, low-temperature natural thawing by leaving frozen foods in a refrigerator, and low-temperature air thawing and freezing in which cold air is applied to frozen foods left in a refrigerator using an electric fan. High-frequency heating thawing, which involves heating food in a microwave oven, is known. but,
While natural thawing, low-temperature natural thawing, and low-temperature blast thawing have the disadvantage of requiring a long time to thaw, high-frequency heating thawing
Although it can be thawed quickly, it has the disadvantage that flavor components such as meat juices thaw out, resulting in a decrease in the quality of the food. Therefore, the following decompression device has been proposed. This thawing device includes a first electric heater that heats indoor air in the upper part of the thawing chamber and an electric fan that circulates the indoor air, and has a temperature sensor in the lower part of the thawing chamber that is heated by a second electric heater. It is equipped with a mounting plate and is one piece. Then, when the user opens and closes the door of the thawing chamber, places the frozen food on the placement plate, and presses the thawing start button, the first control unit is activated. Power is started to be applied to the second electric heater and the electric fan, and the frozen food is heated from above and below by heat transfer by the hot air and heat conduction by the heating plate, and begins to thaw. When thawing is finished, the temperature sensor on the plate on which the frozen food is placed detects the thawing temperature, and the control unit stops the electricity supply and opens and closes the electric damper in the thawing chamber to fill the thawing chamber with cold air. is introduced to maintain the indoor temperature at a so-called partial temperature (-3°C).

装置の簡素化を図ることができる。[Example] Hereinafter, the present invention will be explained in detail with reference to illustrated examples. Figure 2 is a vertical cross-sectional view showing one embodiment of the defrosting device of the refrigerator-freezer with a defrosting device of the present invention, in which 1 is a thawing chamber with a door 2, and 3 is an upper part of this thawing chamber l for heating indoor air. 4 is an electric fan that circulates indoor air; 5 is a room temperature sensor that detects the room temperature; 6 is a temperature sensor 7 at the lower part of the thawing chamber l; A mounting plate that is heated via the aluminum plate 9 and on which the frozen food A is placed; IO is an electric damper that opens and closes to introduce cold air C into the thawing chamber 1; II is the room temperature sensor 5. Temperature sensor 7
Based on the detection signal of the first. This is a control unit that controls on/off the second electric heaters 3 and 8, the electric fan 7, and the electric damper 10. The control unit 11 includes a microcomputer, monitors the temperature indicated by the detection signal of the temperature sensor 7, and maintains the temperature for a certain period of time t from a predetermined steady-state value To (see FIG. 2).
. a determining means for determining whether a local maximum value greater than or equal to a predetermined value Tmax has been reached within a predetermined time period 1. After the above 1. A power supply means for starting power supply to the second electric heaters 3 and 8 and the electric fan 4 is provided. Note that the above-mentioned certain time t. The predetermined value T maX is given in advance as an appropriate common value in consideration of the type and size of the frozen food to be thawed and the timing of opening/closing the door and inserting the frozen food, and is stored in the memory of the microcomputer. Moreover, after the start of power supply, the control unit 11 controls the first temperature based on the detection signals from the room temperature sensor 5 and the temperature sensor 7 so that the surface temperature of the frozen food A does not exceed a certain temperature that degrades the quality. Second
In addition to controlling the electric heaters 3 and 8 on and off, when the detection signal level of the temperature sensor 7 reaches a certain thawing end temperature, the power supply to the first and second electric heaters 3 and 8 is stopped, and the electric damper The temperature inside the freezer compartment 1 is controlled to be the so-called 7-year temperature (-3° C.) by opening and closing the lO 2 on the basis of the detection signal from the room temperature sensor 5. The operation of the decompressing device having the above configuration will be described below with reference to FIG. The user opens the door 2 of the thawing chamber 1 and inserts the frozen food A to be thawed onto the placing plate 6 in the room. After placing it, door 2 is closed. At this time, as shown in FIG. 2, the temperature detected by the temperature sensor 7 of the mounting plate 6 rises from the steady value To('C) when the door is closed at time P+ due to the inflow of outside air due to the door opening. Thereafter, due to the placement of the frozen food and the closing of the door, the temperature starts to decline and reaches a maximum value Tm at time Pm. The control unit 11 monitors the detection signal from the temperature sensor 7, and determines that the local maximum value Tm is equal to or greater than a predetermined value T max stored in advance, and that the local maximum value Tm appears for a pre-stored part of the time from time P1. t. It is determined that it is within the range. Based on this determination, the first . Power supply to the second electric heaters 3 and 8 and the electric fan 4 is started. In this way, by simply putting frozen food A into the thawing chamber 1, the first thawing
Thawing of the frozen food A is started by heat transfer of hot air from above by the electric heater 3 and electric fan 4 and heat conduction from below by the second electric heater 8. In addition, if the frozen food A is not placed on the placement plate 6 even after the door 2 is opened, or if the door 2 is not closed even after the frozen food A is placed, the detection signal of the temperature sensor 7 will be within the above specified time L0. The local maximum value (Tm
) does not appear, the control unit ll determines that no, and the first
．． Power supply to the 21i-th heaters 3 and 8 and the electric fan 4 is not started. In other words, erroneous decompression operations are prevented. Next, the control unit II controls the first and second electric heaters 3.8 on and off based on the detection signals of the room temperature sensor 5 and the temperature sensor 7 during thawing to keep the surface temperature of the frozen food A constant. When the temperature is maintained below the thawing temperature and the level of the detection signal reaches a certain thawing temperature, the first. The power supply to the second electric heater 3.8 is stopped to end the defrosting operation. Then, based on the detection signal from the room temperature sensor 5, the electric damper 10 is opened and closed to control the temperature in the freezer compartment l to a so-called burnt temperature. In the above embodiment, the room temperature sensor 5 and the electric damper lO are provided, and the control unit 10 controls the room temperature sensor 5 and the temperature sensor 7.
Both electric heaters 3.8 are controlled on/off based on the detection signal of , to properly maintain the surface temperature of the frozen food A during thawing, and after thawing is completed, the electric damper lO is activated based on the detection signal of the room temperature sensor 5. Since the inside of the thawing chamber 1 is maintained at a partial temperature by opening and closing, there is an advantage that the quality of the frozen food A does not deteriorate and the frozen food A can be immediately cooked after thawing. Note that the discrimination means and power supply means of the present invention are not limited to the microcomputer of the embodiment, but may be constructed of other electric circuits, and the room temperature sensor of the embodiment may be omitted. [Effects of the Invention] As is clear from the above explanation, the refrigerator-freezer with a thawing device of the present invention monitors the temperature indicated by the detection signal of the temperature sensor of the mounting plate on which frozen food is placed, by the determination means of the control unit. , it is determined whether or not this temperature has reached a maximum value of a predetermined value or more within a predetermined time from a predetermined steady value, and when it is determined to be positive, the power supply means causes the first
．． Since power is supplied to the second electric heater and the electric fan, defrosting can be started automatically without pressing the defrost start button like in the past, making it easy to use and reducing the user's sense of inconvenience. The device can be simplified by omitting the thawing start button.
