發明概要發明要解決的問題 Summary of the invention The problem to be solved by the invention

根據檢測對象物的溫度分佈並與該溫度分佈相應地控制微波輸出的方式，能夠實現均勻的解凍。但是，在這樣的方式中，為了一邊依次監控溫度分佈一邊控制微波輸出，需要大量感測器等，會使裝置結構複雜化、成本增加。另外，也存在不使用這樣的感測器的解凍控制的技術，但是存在必須使用專用的解凍托盤等限制。Uniform thawing can be achieved by controlling the microwave output according to the temperature distribution of the object to be detected. However, in such a system, in order to control the microwave output while sequentially monitoring the temperature distribution, a large number of sensors and the like are required, which complicates the structure of the device and increases the cost. In addition, there is also a technique of thawing control without using such a sensor, but there are limitations such as the need to use a dedicated thawing tray.

用以實施發明之形態form for carrying out the invention

下面，參照附圖來詳細說明實施方式。此外，以下的實施方式不限於申請專利範圍所涉及的發明，另外，在實施方式中說明的特徵的全部組合不一定是發明所必需的。也可以將在實施方式中說明的多個特徵中的兩個以上的特徵任意組合。另外，對相同或同樣的結構標注相同的附圖標記，省略重複的說明。Embodiments will be described in detail below with reference to the drawings. In addition, the following embodiments are not limited to the inventions related to the claims, and all combinations of the features described in the embodiments are not necessarily essential to the invention. Two or more of the features described in the embodiments may be combined arbitrarily. In addition, the same reference numerals are assigned to the same or similar configurations, and overlapping descriptions are omitted.

圖1是實施方式中的加熱炊具1的主要部分截面圖。加熱炊具1可以是藉由向收納庫內輻射微波來將配置於收納庫內的烹調對象物進行加熱的所謂的微波爐。加熱炊具1具備電源2、磁控管3、波導管4、以及用於收納作為烹調對象物的食品6的收納庫5。Fig. 1 is a sectional view of main parts of a heating cooker 1 according to the embodiment. The heating cooker 1 may be a so-called microwave oven that heats an object to be cooked placed in the storage by radiating microwaves into the storage. The heating cooker 1 includes a power supply 2 , a magnetron 3 , a waveguide 4 , and a storage 5 for storing food 6 as a cooking object.

電源2藉由變壓器方式或逆變器方式來對磁控管3施加規定的電壓。當從電源2對作為產生微波的產生部的磁控管3施加規定的電壓時，產生2.45GHz的微波。從磁控管3產生的微波藉由波導管4被引導到收納庫5內(庫內)。The power supply 2 applies a predetermined voltage to the magnetron 3 by means of a transformer or an inverter. When a predetermined voltage is applied from the power supply 2 to the magnetron 3 which is a generating unit for generating microwaves, microwaves of 2.45 GHz are generated. Microwaves generated from the magnetron 3 are guided into the storage chamber 5 (inside the chamber) via the waveguide 4 .

藉由關閉收納庫5的未圖示的前表面門來使該收納庫5成為密閉空間。在收納庫5中配置有用於載置食品6的托盤7，在托盤7的下方配置有旋轉天線8，該旋轉天線8將藉由波導管4被引導來的微波進行輻射，並將該微波在收納庫5內進行攪拌。旋轉天線8能夠被天線馬達9驅動而旋轉。此外，波導管4和旋轉天線8的配置位置不限於此，例如也可以是波導管4和旋轉天線8配置於收納庫5的上方的結構。另外，也可以不採用旋轉天線8，取而代之地，將托盤7設為轉盤，在微波的輻射期間驅動轉盤使之旋轉。This storage 5 is made into a sealed space by closing the front door which is not shown in figure of the storage 5. As shown in FIG. A tray 7 for placing food 6 is arranged in the storage room 5, and a rotating antenna 8 is arranged below the tray 7. The rotating antenna 8 radiates the microwave guided by the waveguide 4, and radiates the microwave in the Stirring is performed in the storage compartment 5 . The rotating antenna 8 can be driven to rotate by the antenna motor 9 . In addition, the arrangement position of the waveguide 4 and the rotating antenna 8 is not limited to this, For example, the structure which arrange|positions the waveguide 4 and the rotating antenna 8 above the storage 5 may be sufficient. In addition, instead of using the rotating antenna 8, the tray 7 may be used as a turntable, and the turntable may be driven to rotate during microwave radiation.

另外，在加熱炊具1配置有控制板10。在控制板10安裝有統一控制加熱炊具1的動作的控制部(後述)。控制部能夠進行使對微波輸出的強弱的選擇與動作時間組合起來的手動運轉、以及與加熱功能表相應的自動運轉。在自動運轉中，能夠一邊監視庫內溫度、濕度、食品6的重量、紅外線產生狀況等一邊進行動作。然而，可以在加熱炊具1適當配置用於檢測庫內溫度的溫度感測器、用於檢測由於從食品6產生的水蒸氣而升高的濕度的濕度感測器、用於檢測食品的重量的重量感測器、用於檢測從食品6產生的紅外線劑量的紅外線感測器等。除此以外，也可以在加熱炊具1組裝前表面門的開閉探測機構、庫內燈、庫內冷卻風扇、通知部等。但是，它們都是以往以來一般使用的裝置，並且與本發明沒有特別關係，因此在此省略對它們的詳細結構和使用它們進行的處理的說明。In addition, a control panel 10 is disposed on the heating cooker 1 . A control unit (described later) for collectively controlling the operation of the heating cooker 1 is attached to the control panel 10 . The control part can perform manual operation which combines selection of the intensity|strength and weak of microwave output, and operation time, and automatic operation according to a heating function table. During the automatic operation, the operation can be performed while monitoring the temperature, humidity, weight of the food 6, infrared ray generation status, etc. in the storage room. However, a temperature sensor for detecting the temperature inside the chamber, a humidity sensor for detecting the humidity raised due to water vapor generated from the food 6, a sensor for detecting the weight of the food may be appropriately arranged in the heating cooker 1 . A weight sensor, an infrared sensor for detecting the dose of infrared rays generated from the food 6, and the like. In addition, an open/close detection mechanism for the front door, an interior lamp, an interior cooling fan, a notification unit, and the like may be incorporated into the heating cooker 1 . However, these devices are generally used conventionally and have no particular relationship with the present invention, so descriptions of their detailed configurations and processes performed using them are omitted here.

在本實施方式中，磁控管3(產生部)的額定微波輸出(額定高周波輸出，所謂的“微波爐輸出”)例如是900W、600W、500W、300W，磁控管3能夠以切換這些輸出的方式使用。這些輸出值是能夠使磁控管3連續振盪的輸出值。在以比作為額定微波輸出最低值的300W更低的輸出進行加熱的情況下，藉由300W的間歇輸出來實現該加熱。這是由於當使連續輸出低於300W時磁控管3不再振盪。In the present embodiment, the rated microwave output (rated high-frequency output, so-called "microwave output") of the magnetron 3 (generating part) is, for example, 900W, 600W, 500W, 300W, and the magnetron 3 can switch these outputs way to use. These output values are output values capable of continuously oscillating the magnetron 3 . In the case of heating with an output lower than 300W which is the lowest value of the rated microwave output, the heating is realized by an intermittent output of 300W. This is because the magnetron 3 no longer oscillates when the continuous output is made below 300W.

在圖2中示出了安裝於控制板10的控制系統的功能塊圖。可以在控制板10安裝控制部20、磁控管驅動器21、馬達驅動器22、顯示控制器25。控制部20可以由包括存儲程式、資料的記憶體和CPU的通用電腦構成。或者，控制部20也可以由ASIC(Application Specific Integrated Circuit：專用積體電路)或FPGA(Field Programmable Gate Array：現場可程式設計閘陣列)等專用設備實現。磁控管驅動器21包括驅動磁控管3的驅動電路，該驅動電路可以包括高頻變壓器和/或逆變器電路。此外，這樣的磁控管驅動器21也可以組裝於電源2。馬達驅動器22可以包括驅動天線馬達9的驅動電路。顯示控制器25控制顯示部24的顯示。例如，在前表面門配置有操作面板30，在此處組裝有顯示部24。顯示部24例如是LCD(Liquid Crystal Display：液晶顯示器)，在該情況下，顯示控制器25可以包括LCD驅動電路。另外，在操作面板30配置有操作部23，來自操作部23的信號被輸入到控制部20。FIG. 2 shows a functional block diagram of the control system mounted on the control board 10 . A control unit 20 , a magnetron driver 21 , a motor driver 22 , and a display controller 25 may be mounted on the control board 10 . The control unit 20 may be constituted by a general-purpose computer including a memory for storing programs and data, and a CPU. Alternatively, the control unit 20 may also be realized by a dedicated device such as ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array: Field Programmable Gate Array). The magnetron driver 21 includes a drive circuit for driving the magnetron 3 , and the drive circuit may include a high-frequency transformer and/or an inverter circuit. In addition, such a magnetron driver 21 may also be incorporated in the power supply 2 . The motor driver 22 may include a drive circuit that drives the antenna motor 9 . The display controller 25 controls display on the display unit 24 . For example, an operation panel 30 is disposed on the front door, and the display unit 24 is incorporated therein. The display unit 24 is, for example, an LCD (Liquid Crystal Display: liquid crystal display), and in this case, the display controller 25 may include an LCD drive circuit. In addition, an operation unit 23 is disposed on the operation panel 30 , and a signal from the operation unit 23 is input to the control unit 20 .

在圖3中示出了表示操作面板30的外觀結構例的圖。操作部23(指定部)可以包括多個操作鍵(操作按鈕)。具體而言，操作部23可以包括模式鍵31、時間/重量鍵32、輸出切換鍵33、自動功能表鍵34、完成鍵35、開始鍵36、取消鍵37。模式鍵31可以包括：解凍鍵，其用於指定進行食品的解凍的“解凍模式”；米飯鍵，其用於指定進行米飯的加熱的“米飯加熱模式”；以及飲料鍵，其用於指定進行飲料加熱的“飲料加熱模式”。時間/重量鍵32可以包括：10分鐘鍵，其用於以10分鐘為單位指定加熱運轉的時間；1分鐘鍵，其用於以1分鐘為單位指定加熱運轉的時間；以及10秒鐘鍵，其用於以10秒鐘為單位指定加熱運轉的時間。在一例中，1分鐘鍵也起到以100g為單位指定食品6的重量的鍵的作用，另外，10秒鐘鍵也起到用於以10g為單位指定食品6的重量的按鍵的作用。FIG. 3 shows a diagram showing an example of the appearance and configuration of the operation panel 30 . The operation section 23 (specifying section) may include a plurality of operation keys (operation buttons). Specifically, the operation unit 23 may include a mode key 31 , a time/weight key 32 , an output switching key 33 , an automatic menu key 34 , a finish key 35 , a start key 36 , and a cancel key 37 .

It is used to specify the heating operation time in units of 10 seconds. In one example, the 1-minute key also functions as a key for specifying the weight of the food 6 in units of 100 g, and the 10-second key also functions as a key for specifying the weight of the food 6 in units of 10 g.

輸出切換鍵33是用於將微波輸出切換為900W、600W、500W、300W、200W(相當)、100W(相當)等中的任一方的按鍵。自動功能表鍵34是用於指定用於自動運轉的功能表(食品的種類)的按鍵。完成鍵35是用於調節自動運轉時的加熱的強弱或加熱的時間的按鍵。開始鍵36是用於指示加熱的開始的按鍵。取消鍵37是用於指示操作的取消或加熱運轉的中止的按鍵。The output switching key 33 is a key for switching the microwave output to any one of 900W, 600W, 500W, 300W, 200W (equivalent), and 100W (equivalent). The automatic menu key 34 is a key for designating a menu (type of food) for automatic operation.

顯示部24顯示與借助操作部23進行的操作相應的設定內容、加熱炊具1的狀態等。此外，操作部23也可以由以重疊於顯示部24的方式構成的觸摸面板構成。The display unit 24 displays the setting content, the state of the heating cooker 1 , and the like according to the operation performed via the operation unit 23 . In addition, the operation unit 23 may be constituted by a touch panel configured to overlap the display unit 24 .

接著，參照圖4來說明本實施方式中的解凍模式下的加熱運轉。Next, the heating operation in the defrosting mode in this embodiment will be described with reference to FIG. 4 .

在解凍模式下，即使是額定微波輸出的最低值(300W)，在以該值進行連續運轉的情況下輸出也會過強，不適於解凍。因此，在解凍模式下，藉由進行額定微波輸出最低值(300W)的間歇輸出，能夠使總時間的平均的微波輸出減弱。In the defrosting mode, even the lowest value (300W) of the rated microwave output will be too strong for continuous operation at this value, which is not suitable for defrosting. Therefore, in the thawing mode, by intermittently outputting the lowest value of the rated microwave output (300W), the average microwave output over the total time can be weakened.

圖4的(a)示出了實現與200W相當的微波輸出的間歇動作的例子。在該例中，將一個循環設為29秒，將其中最初的20秒設為300W輸出的開啟，將接下來的9秒設為關閉。此外，將一個循環設為29秒的理由是在此假設旋轉天線8的轉速為30rpm，要將一個循環設為與該旋轉週期非同步。在該情況下，當將占空比設為D時，每一個循環的平均輸出為 300・D=300・(20秒/29秒) ≈207W，可以將其設為與200W相當。 (a) of FIG. 4 has shown the example of the intermittent operation which realizes the microwave output equivalent to 200W. In this example, one cycle is set to 29 seconds, the first 20 seconds of which are set to ON for the 300W output, and the next 9 seconds are set to OFF. In addition, the reason why one cycle is set at 29 seconds is that here, assuming that the rotational speed of the rotating antenna 8 is 30 rpm, one cycle is set asynchronously with the rotation period. In this case, when the duty cycle is set to D, the average output per cycle is 300・D=300・(20 seconds/29 seconds) ≈207W, It can be set to be equivalent to 200W.

圖4的(b)示出了實現與100W相當的微波輸出的間歇動作的例子。在該例中，將一個循環(29秒)中最初的10秒鐘設為300W輸出的開啟，將接下來的19秒設為關閉。該情況下的每一個循环的平均输出為 300・D=300・(10秒/29秒) ≈103W，可以將其設為與100W相當。 (b) of FIG. 4 has shown the example of the intermittent operation which realizes the microwave output equivalent to 100W. In this example, the first 10 seconds of one cycle (29 seconds) are set to be on for the 300 W output, and the next 19 seconds are set to be off. The average output of each cycle in this case is 300・D=300・(10 seconds/29 seconds) ≈103W, It can be set to be equivalent to 100W.

同樣地，能夠實現其它平均輸出的間歇動作。例如，在實現與150W相當的微波輸出的情況下，將一個循環(29秒)中最初的15秒設為300W輸出的開啟，將接下來的14秒設為關閉。在該情況下，每一個循環的平均輸出為 300・D=300・(14秒/29秒) ≈155W，可以將其設為與150W相當。 Similarly, intermittent operation of other average outputs can be realized. For example, in the case of realizing a microwave output equivalent to 150W, the first 15 seconds in one cycle (29 seconds) are turned on for 300W output, and the next 14 seconds are turned off. In this case, the average output per cycle is 300・D=300・(14 seconds/29 seconds) ≈155W, It can be set to be equivalent to 150W.

另外，在實現與90W相當的微波輸出的情況下，將一個循環(29秒)中最初的9秒設為300W輸出的開啟，將接下來的20秒設為關閉。在該情況下，每一個循環的平均輸出為 300・D=300・(9秒/29秒) ≈93W 可以將其設為與90W相當。此外，用於決定上述的微波輸出的具體的數值和過程始終只是一例，也可以應用其它數值和過程。 Moreover, in the case of realizing the microwave output equivalent to 90W, in the first 9 seconds of one cycle (29 seconds), the 300W output was turned on, and the next 20 seconds were turned off. In this case, the average output per cycle is 300・D=300・(9 seconds/29 seconds) ≈93W It can be set to be equivalent to 90W. In addition, the specific numerical value and procedure for determining the above-mentioned microwave output are only an example, and other numerical values and procedures can also be applied.

在本實施方式中，進行將額定微波輸出最低值的第一間歇輸出與額定微波輸出最低值的第二間歇輸出組合而成的混合控制，該第二間歇輸出與第一間歇輸出的週期相同，並且該第二間歇輸出的占空比與該第一間歇輸出的占空比不同。根據這樣的混合控制，能夠進行比藉由單一週期的間歇輸出進行的輸出控制更細緻的輸出控制，例如在防止過加熱方面有利。In this embodiment, hybrid control is performed by combining the first intermittent output of the lowest rated microwave output and the second intermittent output of the lowest rated microwave output, the second intermittent output having the same period as the first intermittent output, And the duty cycle of the second intermittent output is different from the duty cycle of the first intermittent output. According to such hybrid control, finer output control can be performed than output control by intermittent output of a single cycle, which is advantageous in preventing overheating, for example.

在圖5中示出了表示由控制部20執行的、解凍模式下的加熱運轉的控制過程的流程圖。藉由按下模式按31的解凍鍵來使該解凍模式開始。FIG. 5 shows a flowchart showing a control procedure of the heating operation in the defrosting mode executed by the control unit 20 . The defrost mode is started by pressing the defrost key of the mode button 31 .

在步驟S1中，控制部20根據來自操作部23的操作信號來設定作為要解凍的對象物的食品6的種類。在一例中，設為針對食品的種類假設了“肉餡/肉片”、“肉(的塊)/魚”、“生魚片”這三個種類。用戶例如能夠藉由在規定時間內按下解凍鍵的次數來指定食品6的種類。例如，當將解凍鍵按壓一次時，選擇“肉餡/肉片”，當按壓兩次時指定“肉(的塊)/魚”，當三次按壓時指定“生魚片”。表示所指定的種類的資料作為種類設定資料存儲於記憶體。In step S1 , the control unit 20 sets the type of the food 6 to be thawed based on the operation signal from the operation unit 23 . In one example, it is assumed that three types of "minced meat/sliced meat", "meat (block)/fish", and "sashimi" are assumed for the type of food. For example, the user can designate the type of food 6 by pressing the defrost key the number of times within a predetermined time. For example, when the defrosting key is pressed once, "minced meat/sliced meat" is selected, when pressed twice, "meat (piece)/fish" is designated, and when pressed three times, "sashimi" is designated. Data representing the designated genre is stored in the memory as genre setting data.

在步驟S2中，控制部20進行食品6的重量的設定。在一例中，控制部20將食品6的重量設定為規定的預設值(例如100g)，用戶例如能夠借助時間/重量鍵32來行進該重量的變更操作。表示所指定的重量的資料作為重量設定資料存儲於記憶體。In step S2, the control part 20 sets the weight of the foodstuff 6. As shown in FIG. In one example, the control unit 20 sets the weight of the food 6 to a predetermined preset value (for example, 100 g), and the user can change the weight using the time/weight key 32 , for example. Data indicating the designated weight is stored in the memory as weight setting data.

在步驟S3中，控制部20進行加熱的完成強度的設定。在本實施方式中，加熱炊具1例如可以具有弱、中(標準)、強1、強2這四個等級的完成強度。但是，完成強度的等級數量不限於特定的數量，等級數量既可以少於四個等級，也可以為四個等級以上，或者還可以沒有這樣的等級。控制部20將作為完成強度的中(標準)設定為規定的預設值，用戶例如能夠藉由操作完成鍵35來變更完成強度。表示所指定的完成強度的資料作為完成強度設定資料存儲於記憶體。In step S3, the control part 20 sets the intensity|strength of completion|finish of heating. In the present embodiment, the heating cooker 1 may have four grades of finished strength of weak, medium (standard), strong 1, and strong 2, for example. However, the number of levels to complete the intensity is not limited to a specific number, and the number of levels may be less than four levels, or may be more than four levels, or there may be no such levels. The control unit 20 sets medium (standard) as the finish strength as a predetermined preset value, and the user can change the finish strength by operating the finish key 35 , for example. Data indicating the designated completion strength is stored in the memory as completion strength setting data.

在步驟S4中，控制部20決定第一間歇輸出的占空比即第一占空比D1以及第二間歇輸出的占空比即第二占空比D2。下面，例示出占空比的決定方法。In step S4, the control part 20 determines the 1st duty ratio D1 which is the duty ratio of the 1st intermittent output, and the 2nd duty ratio D2 which is the duty ratio of the 2nd intermittent output. Next, a method of determining the duty ratio will be exemplified.

例如，在額定微波輸出最低值為300W的情況下，如圖4的例子所示，控制部20將第一占空比D1決定為使第一間歇輸出的微波輸出與200W相當，將第二占空比D2決定為使第二間歇輸出的微波輸出與100W相當。或者，也可以是，控制部20將第一占空比D1決定為使第一間歇輸出的微波輸出與150W相當，將第二占空比D2決定為使第二間歇輸出的微波輸出與100W相當或者與90W相當。For example, in the case where the rated microwave output minimum value is 300W, as shown in the example of FIG. Duty ratio D2 is determined so that the microwave output of the second intermittent output corresponds to 100W. Alternatively, the control unit 20 may determine the first duty ratio D1 so that the microwave output of the first intermittent output corresponds to 150W, and the second duty ratio D2 so that the microwave output of the second intermittent output corresponds to 100W. Or equivalent to 90W.

或者，在步驟S1中設定(指定)的食品的種類為“生魚片”的情況下，控制部20將第一占空比D1設定為使第一間歇輸出的微波輸出與150W相當，將第二占空比D2決定為使第二間歇輸出的微波輸出與100W相當或者與90W相當。另一方面，在步驟S1中設定(指定)的食品的種類不為“生魚片”的情況下，控制部20將第一占空比D1決定為使第一間歇輸出的微波輸出與200W相當，將第二占空比決定為使第二間歇輸出的微波輸出與100W相當或者與90W相當。即，使食品為生魚片的情況下的微波輸出與食品為除此以外的種類的情況下的微波輸出相比進一步減弱。由此，可以防止生魚片的過加熱。Or, when the type of food set (specified) in step S1 is "sashimi", the control unit 20 sets the first duty ratio D1 so that the microwave output of the first intermittent output is equivalent to 150W, and the second The second duty ratio D2 is determined so that the microwave output of the second intermittent output is equivalent to 100W or equivalent to 90W. On the other hand, when the type of food set (specified) in step S1 is not "sashimi", the control unit 20 determines the first duty ratio D1 so that the microwave output of the first intermittent output corresponds to 200W. , the second duty ratio is determined so that the microwave output of the second intermittent output is equivalent to 100W or equivalent to 90W. That is, the microwave output when the food is sashimi is further weakened compared to the microwave output when the food is other types. Thereby, overheating of the sashimi can be prevented.

在步驟S5中，控制部20將額定微波輸出設定為作為最低值的300W。In step S5, the control part 20 sets the rated microwave output to 300 W which is a minimum value.

在步驟S6中，控制部20確認是否按下了取消鍵37。在此，在探測到按下了取消鍵37的情況下，結束解凍模式。如果未探測到取消鍵37的按下，則處理進入步驟S7。In step S6, the control unit 20 checks whether or not the cancel key 37 has been pressed. Here, when it is detected that the cancel key 37 is pressed, the defrosting mode ends. If the pressing of the cancel key 37 has not been detected, the process proceeds to step S7.

在步驟S7中，控制部20確認是否按下了開始鍵36。在此，如果未探測到開始鍵36的按下，則處理返回步驟S6。在探測到開始鍵36的按下的情況下，處理進入步驟S8。In step S7, the control unit 20 checks whether or not the start key 36 has been pressed. Here, if the depression of the start key 36 is not detected, the process returns to step S6. In a case where pressing of the start key 36 is detected, the process proceeds to step S8.

在步驟S8中，控制部20進行在步驟S4中決定的第一占空比D1的第一間歇輸出。此後，在步驟S9中，控制部20進行在步驟S4中決定的第二占空比D2的第二間歇輸出。In step S8, the control part 20 performs the 1st intermittent output of the 1st duty ratio D1 determined in step S4. Thereafter, in step S9, the control unit 20 performs the second intermittent output of the second duty ratio D2 determined in step S4.

本實施方式中的解凍模式下的加熱運轉如上所述。在此，根據與步驟S4相關地說明的例子，在步驟S4中決定的第一占空比D1與第二占空比D2之間的關係處於D1＞D2這樣的關係。根據該關係，與步驟S9中的第二間歇輸出下的微波輸出(例如與100W相當)相比，步驟S8中的第一間歇輸出下的微波輸出(例如與200W相當)被設定為更高的值，因此，在後半段中，能夠一邊利用在前半段被加熱後的食品的熱來融化周圍的冰，一邊以低的輸出使食品逐漸解凍。The heating operation in the defrosting mode in this embodiment is as described above. Here, according to the example described in connection with step S4, the relationship between the first duty ratio D1 and the second duty ratio D2 determined in step S4 is D1>D2. According to this relationship, the microwave output under the first intermittent output in step S8 (e.g. equivalent to 200W) is set to be higher than the microwave output under the second intermittent output in step S9 (e.g. equivalent to 100W). Therefore, in the second half, the food can be gradually thawed with a low output while utilizing the heat of the food heated in the first half to melt the surrounding ice.

下面，說明在步驟S8中進行的第一間歇輸出和在步驟S9中進行的第二間歇輸出的循環持續時間。循環持續時間是指間歇輸出的循環被重複執行的總時間。Next, the cycle durations of the first intermittent output performed in step S8 and the second intermittent output performed in step S9 will be described. The cycle duration is the total time that the cycle of the intermittent output is repeated.

在本實施方式中，可以根據食品的重量來決定第一間歇輸出的循環持續時間和第二間歇輸出的循環持續時間。例如，能夠根據包括在步驟S2中指定的食品的重量的多項式來決定第一間歇輸出的循環持續時間和第二間歇輸出的循環持續時間。In this embodiment, the cycle duration of the first intermittent output and the cycle duration of the second intermittent output can be determined according to the weight of the food. For example, the cycle duration of the first intermittent output and the cycle duration of the second intermittent output can be determined from a polynomial including the weight of the foodstuff specified in step S2.

當將在步驟S2中指定的食品的重量設為M、將第一間歇輸出的循環持續時間設為T1、將第二間歇輸出的循環持續時間設為T2時，藉由下式來表示T1和T2。When the weight of the food designated in step S2 is set as M, the cycle duration of the first intermittent output is set as T1, and the cycle duration of the second intermittent output is set as T2, T1 and T2.

T1=α1・M+β1 T2=α2・M+β2 其中，α1、α2、β1、β2分別是針對重量M的係數。 T1=α1・M+β1 T2=α2・M+β2 Here, α1, α2, β1, and β2 are coefficients for the weight M, respectively.

係數α1、α2、β1、β2可以具有與在步驟S1中指定的食品的種類相應的值。下面，示出與食品的種類相應的各係數的例子。但是，這些係數的值只是一例，各係數不限於這些值。Coefficients α1, α2, β1, and β2 may have values corresponding to the type of food specified in step S1. Next, an example of each coefficient according to the type of food is shown. However, the values of these coefficients are just examples, and each coefficient is not limited to these values.

(1)肉餡/肉片(與200W相當+與100W相當)： α1=0.3，β1=-30，α2=0.75，β2=120 (2)肉(的塊)/魚(與200W相當+與100W相當)： α1=0.4，β1=-20，α2=0.6，β2=90 (3)生魚片(與150W相當+與90W相當)： α1=0.3，β1=0，α2=1.0，β2=100 (1) minced meat/meat slices (equal to 200W + equivalent to 100W): α1=0.3, β1=-30, α2=0.75, β2=120 (2) Meat (blocks)/fish (equal to 200W + equivalent to 100W): α1=0.4, β1=-20, α2=0.6, β2=90 (3) Sashimi (equal to 150W + equivalent to 90W): α1=0.3, β1=0, α2=1.0, β2=100

當示出具體的一例時，在食品的種類為“肉餡/肉片”且食品的重量M被設定為200g的情況下，使用於解凍的加熱運轉時間T成為下面那樣。When a specific example is shown, when the type of food is "minced meat/meat slices" and the weight M of the food is set to 200 g, the heating operation time T for thawing is set as follows.

T=第一間歇輸出(與200W相當)的循環持續時間T1 +第二間歇輸出(與100W相當)的循環持續時間 =(0.3×200g-30)+(0.75×200g+120) =300秒 T = cycle duration T1 of the first intermittent output (equivalent to 200W) + Cycle duration for second intermittent output (comparable to 100W) =(0.3×200g-30)+(0.75×200g+120) =300 seconds

另外，在食品的種類為“生魚片”且食品的重量M被設定為200g的情況下，使解凍所花費的加熱運轉時間T成為下面那樣。In addition, when the type of food is "sashimi" and the weight M of the food is set to 200 g, the heating operation time T for thawing is set as follows.

T=第一間歇輸出(與150W相當)的循環持續時間T1 +第二間歇輸出(與90W相當)的循環持續時間T2 =(0.3×200g)+(1.0×200g+100) =300秒 T = cycle duration T1 of the first intermittent output (equivalent to 150W) + Cycle duration T2 of the second intermittent output (comparable to 90W) =(0.3×200g)+(1.0×200g+100) =300 seconds

並且，控制部20也可以根據在步驟S3中指定的完成強度來調整第一間歇輸出的循環持續時間T1和第二間歇輸出的循環持續時間T2。例如，預先設定了與完成強度相應的係數。每個完成強度的係數例如是下面那樣的係數。但是，這些係數的值只是一例，各係數不限定於這些值。另外，上述的與重量有關的數值也只是一例，也可以應用其它數值。In addition, the control unit 20 may adjust the cycle duration T1 of the first intermittent output and the cycle duration T2 of the second intermittent output according to the completion intensity specified in step S3. For example, a coefficient corresponding to the completion strength is set in advance. The coefficient for each completion strength is, for example, the following coefficient. However, the values of these coefficients are just examples, and each coefficient is not limited to these values. In addition, the numerical value related to the weight mentioned above is only an example, and other numerical values can also be applied.

弱： 0.9，中(標準)：1，強1 ： 1.1，強2 ： 1.2 Weak : 0.9, Medium (Standard): 1, Strong 1 : 1.1, Strong 2 : 1.2

控制部20對用於解凍的加熱運轉時間T乘上與上述的完成強度相應的係數。例如，在完成強度為“弱”的情況下，加熱運轉時間被調整為0.9×T。0.9×T例如是指使各循環的開啟時間和關閉時間各自變成0.9倍。同樣地，在完成強度為“強1”的情況下，加熱運轉時間被調整為1.1×T，在完成強度為“強2”的情況下，加熱運轉時間被調整為1.2×T。The control unit 20 multiplies the heating operation time T for thawing by a coefficient corresponding to the completion intensity described above. For example, when the completion intensity is "weak", the heating operation time is adjusted to 0.9×T. 0.9×T means, for example, that the ON time and the OFF time of each cycle are each multiplied by 0.9. Similarly, when the completion intensity is "Strong 1", the heating operation time is adjusted to 1.1×T, and when the completion intensity is "Strong 2", the heating operation time is adjusted to 1.2×T.

像這樣，藉由由用戶指定的完成強度來調整加熱運轉時間。由此，能夠將基於用戶的經驗的解凍完成程度的預測反映到加熱運轉時間中。In this way, the heating operation time is adjusted by the completion intensity specified by the user. Thereby, it is possible to reflect the prediction of the completion degree of thawing based on the user's experience on the heating operation time.

根據以上說明的實施方式，能夠不損害解凍的完成程度，另外，能夠實現不使裝置結構複雜化且在成本方面有利的解凍功能。According to the embodiment described above, it is possible to realize a cost-effective defrosting function without complicating the structure of the device without compromising the degree of completion of defrosting.

本發明不限於上述的實施方式，在發明的主旨的範圍內能夠進行各種變形變更。The present invention is not limited to the above-described embodiments, and various modifications and changes are possible within the scope of the gist of the invention.
