[0033] (Configuration of thawing device 1)

[0034] figure 1 It is a block diagram showing the configuration of main parts of the thawing device 1 according to the first embodiment of the present invention. As shown in the figure, the thawing device 1 includes: a high-frequency power supply 11, a radiator 12, a matching circuit 13, a radiator 14, a housing 15, a pair of electrodes 16 and 17, a temperature measuring device 18, a circulator 19, and a detection unit 20 and the control unit 21. The thawing device 1 is a device for thawing an object 22 by irradiating a frozen object with radio waves. Object 22 is, for example, frozen food.

[0035] The high-frequency power supply 11 generates high-frequency power using power input from the outside of the thawing device 1 . The high-frequency power supply 11 supplies the generated high-frequency power to the matching circuit 13 . In the present embodiment, "radio wave" refers to an electric signal or radio wave (electromagnetic...

[0068] Figure 6 It is a block diagram showing the configuration of main parts of the thawing device 2 according to the second embodiment of the present invention. As shown in the figure, the thawing device 2 includes the same components as those included in the thawing device 1 according to the first embodiment. However, the thawing device 2 is different from the thawing device 1 according to the first embodiment in that the temperature measuring device 18 is attached to the radiator 12 instead of the radiator 14 . In the thawing device 2 , the temperature measuring device 18 measures heat, which is the heat released from the entire high-frequency power source 11 , by measuring the temperature of the radiator 12 having a known heat capacity. In this way, the temperature measuring device 18 indirectly measures the temperature of the high-frequency power source 11 by measuring the temperature of the heat sink 12 .

[0075] Figure 8 It is a block diagram showing the configuration of main parts of the thawing device 3 according to the third embodiment of the present invention. As shown in the figure, the thawing device 3 further includes a temperature measuring device 23 in addition to the components included in the thawing device 1 according to the first embodiment. In the thawing device 3 , the temperature measurer 18 is attached to the radiator 14 , and the temperature measurer 23 is attached to the radiator 14 . The control unit 21 is connected to at least the high frequency power supply 11 , the matching circuit 13 , the temperature measurer 18 , the detection unit 20 and the temperature measurer 23 . Similar to the first embodiment, the temperature measuring device 18 indirectly measures the temperature of the matching circuit 13 by measuring the temperature of the heat sink 14 . The temperature measuring device 23 indirectly measures the temperature of the high-frequency power sup...

Abstract

An object of an embodiment of the present invention is to stop thawing an object at the appropriate time. A temperature measuring device (18) measures the temperature of a matching circuit (13) or a high-frequency power supply (11). A controller unit (21) controls irradiation of an object (22) with radio frequency waves and stopping thereof based on the measured temperature.

Description

technical field [0001] The present invention relates to a thawing device and thawing method for thawing objects such as frozen food. Background technique [0002] Conventionally, thawing apparatuses using microwaves are generally used for thawing objects such as frozen foods. Water absorbs microwaves much more than ice does. Therefore, if a portion of a frozen product melts rapidly during thawing, the degree of microwave absorption of that portion increases dramatically. As a result, the thawing of the portion is further accelerated, thereby accelerating the overheating of the portion. This phenomenon is called Runaway and causes objects to be thawed unevenly by microwaves. If a runaway occurs, the temperature on the surface of the object will be different from the temperature inside. Thus, it is difficult to judge whether the object has been properly thawed without destroying the object. [0003] In addition, conventionally, there has been proposed a thawing device tha...
