Therefore, in the left-right direction of the heating chamber bottom surface 28a, the temperature of the plurality of places can be detected at one time, from the deep side of the heating chamber 28 (the heating chamber deep wall surface 28b side) to the front side (the door 2 side). In the range, the temperature of the entire area of the bottom surface 28a of the heating chamber can be detected by rotating the infrared sensor 52. Specifically, the overall temperature of the table top 24 placed at the bottom surface 28a of the heating chamber is detected.

元件符號54，係為筒狀之單元箱，並在最大徑部處配置基板53，且設置有使紅外線感測器52之透鏡 部52a作面臨的窗部54a。又，係藉由在單元箱54之材料中含有碳，來將單元箱54之特性設為導電材，藉由此，來防止外來之雜訊的對於單元箱54內之侵入。 The component symbol 54 is a cylindrical unit case, and the substrate 53 is disposed at the largest diameter portion, and a lens for the infrared sensor 52 is disposed. The portion 52a serves as a facing window portion 54a. Further, by including carbon in the material of the unit case 54, the characteristics of the unit case 54 are made of a conductive material, thereby preventing invasion of foreign noise into the cell case 54.

元件符號55，係為由金屬板所成之閘門。閘門55，係為在並不使用紅外線感測器52時而將後述之觀測窗44a作關閉者(參考圖8)。又，為了防止加熱室28之溫度傳導至單元箱54處，係以會使冷卻風在單元箱54之外周處流動的方式，而以會形成沿著單元箱54之外周而設置有空隙之風路55c的方式來配置閘門55，並在前述風路55c處設置有成為冷卻風39之流入流出口之開口55a和開口55b。 The component symbol 55 is a gate formed of a metal plate. The shutter 55 is a person who closes the observation window 44a to be described later when the infrared sensor 52 is not used (refer to FIG. 8). Further, in order to prevent the temperature of the heating chamber 28 from being transmitted to the unit case 54, the cooling air is caused to flow around the outer circumference of the unit case 54, so that a wind having a gap along the outer circumference of the unit case 54 is formed. The gate 55 is disposed in a manner of a path 55c, and an opening 55a and an opening 55b which serve as an inflow outlet of the cooling air 39 are provided at the air passage 55c.

元件符號56，係為定位凸部，並以當以將紅外線感測器52之偵測點對位於基準位置(圖4之偵測點a)的方式而使前述控制部對於馬達51之轉動作了控制時能夠對於紅外線感測器52之偵測點之基準位置作修正的方式，來在藉由閘門55而將觀測窗44a作了關閉時，藉由在定位凸部56與被設置在紅外線箱48中之擋止部(未圖示)相互作了抵接的狀態下來使轉動軸51a滑動，而能夠對於前述控制部所控制的基準位置和成為紅外線感測器52之進行偵測的基準位置之偵測點a的位置作修正。 The component symbol 56 is a positioning convex portion, and the control portion is rotated with respect to the motor 51 in such a manner that the detection point of the infrared sensor 52 is located at the reference position (detection point a of FIG. 4). When the control is capable of correcting the reference position of the detection point of the infrared sensor 52, when the observation window 44a is closed by the shutter 55, by positioning the convex portion 56 and being disposed in the infrared When the stoppers (not shown) in the case 48 are in contact with each other, the rotation shaft 51a is slid, and the reference position controlled by the control unit and the reference for detecting the infrared sensor 52 can be used. The position of the detection point a of the position is corrected.

元件符號44，係為朝向加熱室28之內側方向作了突出的圓弧狀之觀測部，轉動軸51a之轉動中心、和筒狀之單元箱54之中心、和沿著單元箱54之外周所設置並且被彎折成圓弧狀之閘門55的圓弧之中心、以及圓弧 狀之觀測部44之各中心位置，係均成為相同之位置。元件符號44a，係為設置在觀測部44處之觀測窗，並將成為紅外線感測器52之進行檢測的視野範圍之範圍作開口。又，為了防止在微波加熱時之從觀測窗44a而來的微波漏洩，在觀測窗44a之周圍外側，係以2mm程度而設置有立起壁(burring)44b。 The component symbol 44 is an arc-shaped observation portion that protrudes toward the inner side of the heating chamber 28, the rotation center of the rotation shaft 51a, the center of the cylindrical unit case 54, and the outer circumference of the unit case 54. The center of the arc of the gate 55 that is set and bent into an arc shape, and the arc The center positions of the observation portions 44 are all at the same position. The component symbol 44a is an observation window provided at the observation unit 44, and opens a range of the visual field range in which the infrared sensor 52 detects. Further, in order to prevent leakage of microwaves from the observation window 44a during microwave heating, a burring 44b is provided around the observation window 44a to a depth of about 2 mm.

藉由使觀測部44朝向加熱室28之內側突出，係成為能夠以最低限度之狹窄的觀測窗開口範圍來進行廣範圍之溫度偵測。 By projecting the observation unit 44 toward the inside of the heating chamber 28, it is possible to perform a wide range of temperature detection with a minimum narrow observation window opening range.

元件符號49係為凸部，並為使紅外線箱48和紅外線單元50從加熱室頂板28c而離開者，藉由構成為僅有凸部49之與加熱室頂板28c之間的接觸，來構成為在加熱時使藉由網格加熱手段12或熱風單元11等之加熱器所加熱了的加熱室頂板28c之溫度難以傳導至紅外線單元50處。 The component symbol 49 is a convex portion, and the infrared box 48 and the infrared ray unit 50 are separated from the heating chamber top plate 28c, and are configured such that only the convex portion 49 is in contact with the heating chamber top plate 28c. The temperature of the heating chamber top plate 28c heated by the heater such as the grid heating means 12 or the hot air unit 11 is hardly conducted to the infrared unit 50 at the time of heating.

藉由圖4、圖5，針對被搭載在控制基板23處的控制手段23a之紅外線感測器52之測定要領作說明。 The measurement method of the infrared sensor 52 of the control means 23a mounted on the control board 23 will be described with reference to Figs. 4 and 5 .

圖4，係為對於將酒裝入至杯子並進行溫酒的情況時之紅外線感測器之動作作說明之圖，圖5，係為對於將酒裝入至日本酒瓶中並進行溫酒的情況時之紅外線感測器之動作作說明之圖。在圖4中，於偵測點f處係能夠直接掌握到被加熱物60c之液面60c1。此係因為身為杯子的容器60之口為廣之故。在圖5中，係並無法直接掌握 到被加熱物60c之液面60c1，此係因為身為日本酒瓶的容器60之口為狹窄之故。 Fig. 4 is a view for explaining the action of the infrared sensor when the wine is put into the cup and warm wine is used, and Fig. 5 is for charging the wine into a Japanese wine bottle and performing warm wine. In the case of the situation, the action of the infrared sensor is illustrated. In Fig. 4, the liquid level 60c1 of the object 60c can be directly grasped at the detection point f. This is because the mouth of the container 60 which is a cup is wide. In Figure 5, the system is not directly graspable. It is to the liquid surface 60c1 of the object 60c to be heated, because the mouth of the container 60 which is a Japanese wine bottle is narrow.

紅外線感測器52，係使能夠藉由一次的測定來對於8個點進行測定的感測器，藉由馬達51來從基準位置(圖4、偵測點a)起直到終點位置(圖4，偵測點h)地而使紅外線感測器52作1次3度的14次之轉動移動，來進行總計15列之測定，並檢測出左右方向8點×前後方向15列之120個場所之溫度。之後，從前述終點位置起直到前述基準位置為止，紅外線感測器52係並不進行測定地而直接回到前述基準位置。 The infrared sensor 52 is a sensor that can measure eight points by one measurement, and is driven by the motor 51 from the reference position (FIG. 4, detection point a) to the end position (FIG. 4). At the detection point h), the infrared sensor 52 is rotated by 14 times of 3 times, and a total of 15 columns are measured, and 120 places in the left-right direction 8 points × 15 directions in the front-rear direction are detected. The temperature. Thereafter, from the end position to the reference position, the infrared sensor 52 directly returns to the reference position without performing measurement.

溫度偵測，係反覆進行「從前述基準位置起直到前述終點位置為止地而使紅外線感測器52作1次3度的14次之轉動移動，來進行15列之測定，之後，從終點位置起而回到基準位置」之動作。 In the temperature detection, the infrared sensor 52 is rotated 14 times in three steps from the reference position to the end position, and the measurement is performed in 15 columns, and then the end position is obtained. The action of returning to the reference position.

對於藉由紅外線感測器52所偵測到的被加熱物60c之溫度和被記憶在控制手段23a中之特定溫度H(例如30℃)作比較，並將所偵測到的溫度到達了特定之判定溫度H的到達時間(從加熱開始起之經過時間)，作為初期加熱時間T1而作記憶。控制手段23a之控制，係於後再述。 Comparing the temperature of the object 60c detected by the infrared sensor 52 with a specific temperature H (for example, 30 ° C) memorized in the control means 23a, and the detected temperature reaches a specific temperature The arrival time of the determination temperature H (the elapsed time from the start of heating) is stored as the initial heating time T1. The control of the control means 23a will be described later.

接下來，針對紅外線感測器52之轉動移動作說明。 Next, the rotational movement of the infrared sensor 52 will be described.

在作為裝入有被加熱物(酒)60c之使上方作了開口的容器60之例，而將杯子載置在被設置於加熱室 底面28a處之桌台板24上並開始了加熱時，在磁控管33進行安定發訊的1~2秒間，藉由閘門55來將觀測窗44a關閉(參考圖8)，以防止起因於磁控管33之發訊開始時的不安定之發訊所導致的雜訊進入至紅外線感測器52中。 In the case of the container 60 which is opened above the object to be heated (wine) 60c, the cup is placed in the heating chamber. When the heating is started on the table top 24 at the bottom surface 28a, the observation window 44a is closed by the shutter 55 for 1 to 2 seconds during which the magnetron 33 performs the stable communication (refer to FIG. 8) to prevent the cause of The noise caused by the unstable transmission at the start of the transmission of the magnetron 33 enters the infrared sensor 52.

在磁控管33之發訊安定之後，控制手段23a係以使馬達51之轉動軸51a轉動至基準位置處的方式來進行控制。藉由使轉動軸51a轉動至基準位置，來使單元箱54轉動，紅外線感測器52之透鏡部52a之朝向，亦係轉動至能夠對於基準位置之偵測點a進行偵測的位置(參考圖4、圖6)。此時，冷卻風39由於係在紅外線感測器52之透鏡部52a處流動並從感測器窗部44a來朝向加熱室28流動，因此係防止對於透鏡部52a之髒污的附著。 After the transmission of the magnetron 33 is stabilized, the control means 23a is controlled such that the rotation shaft 51a of the motor 51 is rotated to the reference position. By rotating the rotation shaft 51a to the reference position, the unit case 54 is rotated, and the orientation of the lens portion 52a of the infrared sensor 52 is also rotated to a position where the detection point a of the reference position can be detected (refer to Figure 4, Figure 6). At this time, since the cooling air 39 flows through the lens portion 52a of the infrared sensor 52 and flows from the sensor window portion 44a toward the heating chamber 28, adhesion to the lens portion 52a is prevented.

藉由使單元箱54轉動，被加熱物60c之溫度的檢測係從前述之基準位置(偵測點a)起而朝向桌台板24之偵測點b、偵測點c前進，若是單元箱54更進一步轉動，則係在高度方向上而對於杯子(容器60)之外側的溫度進行偵測，而偵測出從偵測點d起至偵測點e之溫度。在偵測點到達了杯子(容器60)之開口部之頂點之後，在偵測點f處而偵測出被加熱物60c之表面的溫度，接著，在偵測點g處而偵測出杯子(容器60)之內側的溫度，接著，在偵測點h處而偵測出桌台板24之溫度。 By rotating the unit case 54, the temperature of the object to be heated 60c is detected from the aforementioned reference position (detection point a) toward the detection point b and the detection point c of the table board 24, if it is a unit box Further rotation of 54 detects the temperature outside the cup (container 60) in the height direction, and detects the temperature from the detection point d to the detection point e. After the detection point reaches the apex of the opening of the cup (container 60), the temperature of the surface of the object 60c is detected at the detection point f, and then the cup is detected at the detection point g. The temperature inside the container (container 60) is then detected at the detection point h to detect the temperature of the table top 24.

偵測點a~偵測點h之溫度偵測範圍的溫度之偵測，係在使單元箱54轉動之去程的單程中而進行，在 直到終點為止地而進行了溫度偵測之後，於回程中，在途中係並不進行測定而並不進行溫度之偵測，而在再度回到了基準位置處之後，再度以偵測點a~偵測點h而依序進行。 The detection of the temperature of the temperature detection range of the detection point a to the detection point h is performed in a single pass of the outward movement of the unit box 54. After the temperature detection is performed until the end point, in the return journey, the measurement is not performed on the way without detecting the temperature, and after returning to the reference position again, the detection point a~ is detected again. The measurement point h is performed in sequence.

溫度之偵測數量，係可依據需求來作改變，前述之偵測點a~偵測點h，係為說明用之例，並如同前述一般而測定15列的資料。 The number of detected temperatures can be changed according to the requirements. The above detection points a to detection points h are examples for description, and 15 columns of data are measured as described above.

又，溫度之偵測，於正在進行溫度之偵測的期間中，係停止馬達51之轉動並進行偵測，在進行了偵測之後，再進行轉動。為了正確地偵測出溫度，係以停止轉動並進行測定為理想。 Moreover, the detection of the temperature stops the rotation of the motor 51 and detects it during the ongoing temperature detection, and then performs the rotation after the detection. In order to accurately detect the temperature, it is desirable to stop the rotation and perform the measurement.

例如，在加熱初始時，係停止單元箱54之轉動並進行偵測，在進行了偵測之後，係以一定之角度來作轉動，並使轉動停止而進行偵測，在進行了偵測之後，係以一定之角度來作轉動，反覆進行此些動作，而以網眼狀來對於溫度分布作測定。藉由如此這般地來構成，藉由以等角度來對於一定位置之溫度作測定一事而將桌台板24上面區分成複數場所並將溫度檢測出來的紅外線感測器52，係被設置在從被載置於加熱室底面28a處之桌台板24的四邊起而朝向加熱室頂板28c所垂直延伸的假想線之內側的加熱室頂板28c之左右方向的略中央處。 For example, at the initial stage of heating, the rotation of the unit box 54 is stopped and detected. After the detection is performed, the rotation is performed at a certain angle, and the rotation is stopped to detect, after the detection is performed. The rotation is performed at a certain angle, and these actions are repeated, and the temperature distribution is measured in the form of a mesh. With such a configuration, the infrared sensor 52 that divides the upper surface of the table plate 24 into a plurality of places and detects the temperature by measuring the temperature at a certain position at an equal angle is set in From the four sides of the table top 24 placed at the bottom surface 28a of the heating chamber, the heating chamber top plate 28c on the inner side of the imaginary line extending perpendicularly to the heating chamber top plate 28c is slightly centered in the left-right direction.

又，紅外線感測器52之視野，偵測點a和偵測點h係被大略定為對於桌台板24之前後的凸緣部之溫度作偵測之範圍，在紅外線感測器52之橫方向而作了整 列的複數元件之感測器，係被大略定為涵蓋桌台板24之左右而對於溫度作偵測之範圍。藉由此，係成為能夠正確地檢測出被載置於桌台板24之略中央處的被加熱物之溫度。又，紅外線感測器52之轉動，對於偵測出被裝入至杯子60中的被加熱物60c之溫度一事而言，係以進行溫度之測定範圍為廣的轉動為理想。 Moreover, the field of view of the infrared sensor 52, the detection point a and the detection point h are roughly determined as the range for detecting the temperature of the flange portion before and after the table board 24, in the infrared sensor 52 Made in the horizontal direction The sensors of the plurality of elements of the column are roughly defined as covering the left and right sides of the table 24 and detecting the temperature. Thereby, it is possible to accurately detect the temperature of the object to be heated placed at the center of the table top 24. Further, in order to detect the temperature of the object 60c to be charged in the cup 60, the rotation of the infrared sensor 52 is preferably a rotation in which the temperature measurement range is wide.

藉由此種設定，在將杯子60載置在桌台板24之深處側中央時，係成為能夠藉由紅外線感測器50之略下側的偵測點b來偵測出杯子內的被加熱物60c之溫度。 With this setting, when the cup 60 is placed at the center of the deep side of the table top 24, it is possible to detect the inside of the cup by the detection point b on the lower side of the infrared sensor 50. The temperature of the object 60c to be heated.

進而，當根據由重量感測器25所得到的重量資訊和由紅外線感測器52所偵測到的溫度分布資訊，而得知重量資訊係為輕並且係在廣範圍中辨認到溫度分布之溫度上升時，可以判斷出被加熱物60c係為薄且為寬廣者。又，當得知重量資訊係為重並且係僅在狹窄之範圍中辨認到溫度分布之溫度上升時，例如係可以判斷出被加熱物60c係被裝入至高度為高之杯子(容器60)中。 Further, when the weight information obtained by the weight sensor 25 and the temperature distribution information detected by the infrared sensor 52 are used, it is known that the weight information is light and the temperature distribution is recognized in a wide range. When the temperature rises, it can be judged that the object to be heated 60c is thin and wide. Further, when it is known that the weight information is heavy and the temperature rise of the temperature distribution is recognized only in the narrow range, for example, it can be judged that the object 60c is loaded into the cup (container 60) having a high height. .

在本實施例中，雖係在加熱室頂板28c處設置紅外線單元50，但是，紅外線單元50之安裝位置，就算是在安裝於加熱室頂板28c之前方側的情況時，亦同樣的，只要基於與前述記載相同的想法來作設置，便能夠正確地偵測到被加熱物60c之溫度。 In the present embodiment, the infrared unit 50 is provided at the heating chamber top plate 28c. However, the mounting position of the infrared unit 50 is the same as that before the heating chamber top plate 28c. The same idea as described above is provided, and the temperature of the object 60c to be heated can be accurately detected.

在本實施例中，雖係針對裝入至杯子60中之被加熱物60c的溫度偵測之方法來作了詳細說明，但是，就算是在並不使用容器之被加熱物60c為塊狀之大的塊狀 物的情況時，亦由於能夠偵測到塊狀之被加熱物60c的側面之高度方向與上面的溫度，因此係成為能夠詳細地偵測到被加熱物60c之溫度分布。 In the present embodiment, although the method of detecting the temperature of the object 60c to be heated in the cup 60 is described in detail, even if the object 60c to be heated is not used, the block is formed. Large block In the case of the object, since the height direction of the side surface of the block-shaped object to be heated 60c and the temperature of the upper surface can be detected, the temperature distribution of the object 60c to be heated can be detected in detail.

接著，使用圖9~圖13，針對使用有紅外線感測器52和重量感測器25之雙方的被加熱物60c之自動調理之控制方法作說明。以被加熱物60c為酒並且容器60係為杯子的情況為例來作說明。 Next, a method of controlling the automatic conditioning of the object 60c to be heated using both the infrared sensor 52 and the weight sensor 25 will be described with reference to Figs. 9 to 13 . The case where the object to be heated 60c is a wine and the container 60 is a cup is taken as an example.

如同圖12中所示一般，在控制手段23a處，係從輸入手段71、紅外線感測器52、重量感測器25、加熱室溫度感測器80而被進行有輸入，藉由控制手段23a，微波爐加熱手段330係被作控制。 As shown in FIG. 12, at the control means 23a, an input is made from the input means 71, the infrared sensor 52, the weight sensor 25, and the heating chamber temperature sensor 80, by means of the control means 23a. The microwave oven heating means 330 is controlled.

接著，針對加熱工程，使用圖9之流程圖來作詳細說明。 Next, the heating process will be described in detail using the flowchart of FIG.

溫酒，主要係使用杯子和日本酒瓶的2種類之容器60。又，裝入之酒的量也會有各種的不同。一面對於此些之加熱狀況作判斷，一面進行加熱。 Warm wines are mainly two types of containers 60 that use cups and Japanese sake bottles. Also, the amount of wine to be loaded will vary. In the face of the heating conditions of these, the heating is performed while being judged.

首先，在加熱室28中，將裝入有身為被加熱物60c之酒的容器60載置於桌台板24上，並將門3關閉。藉由輸入手段71，來從溫酒選單而選擇加熱、加溫、肌膚溫度之其中一者(工程S0)。各選單之最終溫度，加熱係為50℃，加溫係為40℃，肌膚溫度係為35℃。藉由輸入手段71，來從最終調節而選擇強、中、弱之其中一者(工程S1)。最終調節之「中」，係為以標準的溫度來作最終處理，「強」，係將最終溫度設定為較 標準而更高出約5℃，「弱」，係將最終溫度設定為較標準而更降低約5℃。若是加熱開始之啟動被輸入(工程S2)，則係被設定為事先所設定的加熱輸出P。 First, in the heating chamber 28, the container 60 in which the wine as the object to be heated 60c is placed is placed on the table top 24, and the door 3 is closed. By input means 71, one of heating, warming, and skin temperature is selected from the warm wine menu (Engineering S0). The final temperature of each menu was 50 ° C for heating, 40 ° C for heating, and 35 ° C for skin temperature. By input means 71, one of strong, medium, and weak is selected from the final adjustment (engine S1). The final adjustment of the "medium" is based on the standard temperature for final processing, "strong", the final temperature is set to be The standard is higher by about 5 ° C. "Weak" means that the final temperature is set to be lower by about 5 ° C than the standard. If the start of heating is input (Project S2), it is set to the heating output P set in advance.

接著，藉由重量感測器25，來檢測出被載置在桌台板24上的被加熱物60c和容器60的合計之重量W(工程S3)。當所檢測出的重量W係為特定值W0以下的情況時，係藉由少量模式判定(工程S4)而判定為少量負載模式。當所檢測出的重量W係為特定值W0以下的情況時，係藉由少量負載模式來進行被加熱物60c之加熱(工程S5)。 Next, the total weight W of the object to be heated 60c and the container 60 placed on the table top 24 is detected by the weight sensor 25 (engineer S3). When the detected weight W is equal to or less than the specific value W0, it is determined by a small amount of mode determination (engineer S4) that the load mode is small. When the detected weight W is equal to or less than the specific value W0, the heating of the object 60c is performed by a small amount of load mode (Project S5).

少量負載模式(工程S5)，係為基於所檢測出的重量W，來基於事先對於能夠將酒加熱至所輸入了的溫度之程度的加熱時間所作了確認的結果，而算出總加熱時間Tz，並進行加熱之工程。移行至少量負載模式一事，係想定為在杯子中裝入了1/4程度之酒之後的重量。 The small amount of load mode (engineering S5) is based on the detected weight W, and the total heating time Tz is calculated based on the result of confirming the heating time to the extent that the wine can be heated to the input temperature. And heating works. The transfer of at least the load mode is based on the weight of the 1/4 level wine in the cup.

若是少量模式判定工程(工程S4)之確認結束，則接著，係藉由加熱室溫度感測器80來檢測出加熱室之溫度TH1(S60)，當在加熱室之高溫判定(S61)中而加熱室之溫度TH1為較特定之溫度更高的情況時(N的情況)，係移行至高溫模式並以高溫模式來進行被加熱物60c之加熱(S62)。 When the confirmation of the small-scale mode determination project (the project S4) is completed, the temperature TH1 of the heating chamber is detected by the heating chamber temperature sensor 80 (S60), and is determined in the high temperature of the heating chamber (S61). When the temperature TH1 of the heating chamber is higher than the specific temperature (in the case of N), the temperature is shifted to the high temperature mode and the heating of the object 60c is performed in the high temperature mode (S62).

高溫模式(S62)，係為由於在微波爐調理後之加熱室28之溫度為高的情況時會成為無法藉由紅外線 感測器52來正確地檢測出被加熱物60c之溫度，因此為了避免此種事態所設置者。高溫模式(S62)，係為基於所檢測出的重量W，來基於事先對於能夠將酒加熱至所輸入了的溫度之程度的加熱時間所作了確認的結果，而算出總加熱時間Tz，並進行加熱之工程。 In the high temperature mode (S62), it is impossible to use infrared rays when the temperature of the heating chamber 28 after conditioning in the microwave oven is high. The sensor 52 detects the temperature of the object 60c correctly, and therefore, in order to avoid such a situation. In the high temperature mode (S62), based on the detected weight W, the total heating time Tz is calculated based on the result of confirming the heating time to the extent that the wine can be heated to the input temperature. Heating project.

接著，藉由重量感測器25來檢測出食品之位置(S63)。此工程，係為了檢測出被加熱物60c為被載置於桌台板24之何一位置處並因應於所檢測出之位置來進行加熱控制，而進行者。 Next, the position of the food is detected by the weight sensor 25 (S63). This process is performed in order to detect where the object to be heated 60c is placed at the table plate 24 and to perform heating control in response to the detected position.

紅外線感測器52之能夠進行溫度檢測的範圍，係設為當裝入被加熱物60c之容器60乃身為茶杯或餐盤等之高度為低之容器60的情況時，不論該容器60係被載置於桌台板24之何一位置處，均能夠檢測出被加熱物60c之溫度的範圍。因此，若是將被加熱物60c裝入至杯子等之容器60中並載置於桌台板24上，則相較於茶杯或餐盤，被加熱物60c之表面的面積係為狹窄，高度方向之位置係變高。故而，在載置裝入了被加熱物60c之杯子的情況時，若是載置位置為靠向桌台板24之端部側，則會發生變得無法檢測出被加熱物60c之表面之溫度的情況。因此，係有必要檢測出被加熱物60c之被作載置的位置並因應於該被作載置的位置來進行加熱控制。 The range in which the infrared sensor 52 can perform temperature detection is such that when the container 60 in which the object 60 to be heated is placed in a container 60 having a low height such as a cup or a tray, regardless of the container 60 The temperature of the object to be heated 60c can be detected at any position placed on the table top 24. Therefore, if the object to be heated 60c is placed in the container 60 such as a cup and placed on the table top 24, the area of the surface of the object 60c to be heated is narrower than the cup or the plate. The position is higher. Therefore, when the cup in which the object to be heated 60c is placed is placed, if the placement position is toward the end side of the table top 24, the temperature of the surface of the object 60c cannot be detected. Case. Therefore, it is necessary to detect the position at which the object to be heated 60c is placed and to perform heating control in accordance with the position to be placed.

又，當加熱室28為左右方向較長並且在加熱室底面28a之中央處設置有微波之照射位置的情況時，由於若是被加熱物60c之載置位置越靠向左右之端部側則加 熱效率會越降低，因此，係亦有必要因應於被作載置之位置來針對加熱時之加熱效率作控制。 Further, when the heating chamber 28 is long in the left-right direction and the microwave irradiation position is provided at the center of the heating chamber bottom surface 28a, the position of the object to be heated 60c is increased toward the left and right end portions. The lower the thermal efficiency, it is therefore necessary to control the heating efficiency during heating in response to the position to be placed.

承襲以上內容，針對使用重量感測器25所進行的被加熱物之位置之檢測方法作詳細說明。關於複數個的重量感測器25之配置位置，係如同前述一般，在加熱室底面28a之前側的左側處存在有左側重量感測器25a，並在右側處存在有右側重量感測器25b，並且在深處側之中央處存在有深處側重量感測器25c。藉由此3個的重量感測器25，來支持一枚之特定之重量的桌台板24。在此狀態下，由於在重量感測器25處係已被施加有桌台板24之重量，因此，在控制手段23a處，係構成為將桌台板24之重量先行減去，再對於被載置在桌台板24上的被加熱物60c和容器60的重量作辨識之控制。 In response to the above, a method of detecting the position of the object to be heated using the weight sensor 25 will be described in detail. Regarding the arrangement position of the plurality of weight sensors 25, as in the foregoing, the left side weight sensor 25a is present on the left side of the front side of the heating chamber bottom surface 28a, and the right side weight sensor 25b is present on the right side. And there is a deep side weight sensor 25c at the center of the deep side. A table weight 24 of a particular weight is supported by the three weight sensors 25. In this state, since the weight of the table top 24 has been applied at the weight sensor 25, at the control means 23a, the weight of the table board 24 is first subtracted, and then The weight of the object to be heated 60c and the weight of the container 60 placed on the table top 24 is controlled.

在將被加熱物60c載置於桌台板24之中央時的各重量感測器25之重量之辨識，以比例而言，左側重量感測器25a係為1，右側重量感測器25b係為1，深處側重量感測器25c係成為2，作了載置的被加熱物60c與容器60之重量，係成為各重量感測器25之檢測值之合計的4。不論是在將被加熱物60c載置於桌台板24之何一位置處的情況時，重量感測器25之檢測值的合計均能夠正確地檢測出被加熱物60c與容量60之重量。 In the identification of the weight of each weight sensor 25 when the object to be heated 60c is placed in the center of the table top 24, the left side weight sensor 25a is 1 in proportion, and the right side weight sensor 25b is In the case of 1, the deep side weight sensor 25c is 2, and the weight of the object to be heated 60c and the container 60 is 4, which is the total of the detected values of the respective weight sensors 25. Regardless of the position at which the object to be heated 60c is placed on the table top 24, the total of the detected values of the weight sensor 25 can accurately detect the weight of the object 60c and the capacity 60.

例如，在使被載置於桌台板24處之被加熱物60c之位置從中央而逐漸地朝向右端作了移動的情況時之重量感測器25之檢測值的變化，係成為左側重量感測器 25a之檢測值會變小而右側重量感測器25b之檢測值會變大。此時，當並不存在有加熱室之前後(深度方向)的位置之變化的情況時，左側重量感測器25a之檢測值和右側重量感測器25b之檢測值的合計，係恆常展現有相同之值(參差之範圍)，深處側重量感測器25c之值，係恆常展現有相同之值(參差之範圍)。 For example, when the position of the object to be heated 60c placed on the table top 24 is gradually moved toward the right end from the center, the change in the detected value of the weight sensor 25 is a feeling of weight on the left side. Detector The detected value of 25a becomes smaller and the detected value of the right weight sensor 25b becomes larger. At this time, when there is no change in the position after the heating chamber (the depth direction), the total of the detected values of the left weight sensor 25a and the detected value of the right weight sensor 25b are constantly displayed. There is the same value (the range of the difference), and the value of the deep side weight sensor 25c is constant and exhibits the same value (the range of the difference).

又，若是使被加熱物之位置在左右方向上而位置於中央並且在前後方向上而從中央朝向深處側移動，則左側重量感測器25a之檢測值和右側重量感測器25b之檢測值的比例，係恆常展現有相同之值(參差之範圍)，並且，隨著移動，左側重量感測器25a之檢測值和右側重量感測器25b之檢測值的合計值係變小，相反的，深處側重量感測器25c之檢測值係變大。 Further, if the position of the object to be heated is positioned in the center in the left-right direction and moved in the front-rear direction from the center toward the deep side, the detected value of the left weight sensor 25a and the detection of the right weight sensor 25b are detected. The ratio of the values is constant to exhibit the same value (the range of the difference), and as the movement, the total value of the detected value of the left weight sensor 25a and the detected value of the right weight sensor 25b becomes smaller. Conversely, the detected value of the deep side weight sensor 25c becomes large.

又，依存於被加熱物60c之重量和載置位置，係會有重量感測器25之檢測值為展現負值的情形。此係代表在將被加熱物60c載置於桌台板24之端部時，與所作了載置之端相反側的桌台板24為如同被上舉一般的情形。 Further, depending on the weight of the object to be heated 60c and the placement position, the detected value of the weight sensor 25 may exhibit a negative value. This means that when the object to be heated 60c is placed on the end of the table top 24, the table top 24 on the side opposite to the end on which the object is placed is as if it is lifted.

例如，若是在右側深處載置被加熱物60c，則右側重量感測器25b和深處側重量感測器25c係成為支點，桌台板24之前方的左側會被上舉。因此，左側重量感測器25a之檢測值係變輕，若是在左側深處載置被加熱物，則右側重量感測器25b之檢測值會變輕。針對此，藉由在載置有特定之重量的桌台板24之狀態下而將重量感 測器25之檢測值作為0點來使控制手段23a先行將重量減去，而成為亦能夠檢測出負的重量，就算是在將被加熱物60c載置在較將左側重量感測器25a和右側重量感測器25b以及深處側重量感測器25c作連結之線而更外側處時，亦能夠正確地檢測出被加熱物60c與容器60之重量。 For example, if the object to be heated 60c is placed deep in the right side, the right weight sensor 25b and the deep side weight sensor 25c are fulcrums, and the left side of the table top 24 is lifted. Therefore, the detected value of the left weight sensor 25a becomes light, and if the object to be heated is placed deep in the left side, the detected value of the right weight sensor 25b becomes light. In view of this, the sense of weight is obtained by the state in which the table top 24 of a specific weight is placed. The detected value of the detector 25 is used as the zero point to cause the control means 23a to subtract the weight first, and it is also possible to detect the negative weight even if the object to be heated 60c is placed on the left side weight sensor 25a and When the right weight sensor 25b and the deep side weight sensor 25c are connected to each other and are further outside, the weight of the object 60c and the container 60 can be accurately detected.

重量感測器25之3個場所的配置，係亦可為在前側之中央配置1個場所並在深處側之左右各配置1個場所之合計3個場所。 The arrangement of the three places of the weight sensor 25 may be a total of three places where one place is placed in the center of the front side and one place is placed on the left side of the deep side.

如同以上所作了說明一般，藉由重量感測器25來檢測出被加熱物60c和容器60之重量，並因應於所檢測出的各重量值之比例，來檢測出被加熱物60c之載置位置，當判斷所檢測出的被加熱物60c之位置為位於紅外線感測器52之溫度檢測範圍以內時，前進至下一工程S6。當判斷前述檢測結果係為紅外線感測器52之溫度檢測範圍之外時，係前進至工程S65之死角模式。 As described above, the weight of the object to be heated 60c and the container 60 is detected by the weight sensor 25, and the position of the object to be heated 60c is detected in accordance with the ratio of the detected weight values. When it is determined that the detected position of the object to be heated 60c is within the temperature detection range of the infrared sensor 52, the process proceeds to the next step S6. When it is judged that the aforementioned detection result is outside the temperature detection range of the infrared sensor 52, it proceeds to the blind angle mode of the project S65.

死角模式(S65)，係為基於在前述之高溫模式(S62)中所設定的基於所檢測出的被加熱物60c與容器60之重量W來事先對於能夠將酒加熱至所輸入了的溫度之程度的加熱時間所作了確認的結果，而算出總加熱時間Tz，並進行加熱之工程。 The blind spot mode (S65) is based on the fact that the wine can be heated to the input temperature based on the detected weight W of the object to be heated 60c and the container 60 set in the high temperature mode (S62) described above. The degree of heating time was confirmed as a result, and the total heating time Tz was calculated and the heating was performed.

又，此死角模式，由於係在被加熱物60c之載置場所為被放置於桌台板24之端部側的狀態下來進行加熱，因此，加熱效率係為差，藉由因應於加熱效率來對 於前述總加熱時間Tz作修正並進行加熱，係能夠無關於被加熱物60c之載置場所地來使最終溫度成為一定。 In addition, since the dead angle mode is heated in a state where the object to be heated 60c is placed on the end side of the table top 24, the heating efficiency is poor, and the heating efficiency is caused by the heating efficiency. Correct By correcting and heating the total heating time Tz, the final temperature can be made constant regardless of the place where the object 60c is placed.

進而，當起因於載置場所而導致加熱效率極端性地變差的情況時，考慮到省能源的問題，係亦可使用告知手段來促使使用者多加注意，而並不移行至加熱地來將加熱中止。 Further, when the heating efficiency is extremely deteriorated due to the placement place, in consideration of the problem of energy saving, it is also possible to use a notification means to prompt the user to pay more attention, and not to move to the heating place. The heating is stopped.

又，係構成為，少量模式判定(工程S4)，係優先於加熱室之高溫判定(S61)而進行判定，加熱室之高溫判定(S61)係優先於放置位置之死角判定(S64)而進行判定，就算是難以藉由紅外線感測器52來進行被加熱物60c之溫度檢測的情況時，亦係藉由重量感測器25之檢測結果來算出總加熱時間Tz。 Further, it is configured such that a small amount of mode determination (engineer S4) is determined in preference to the high temperature determination (S61) of the heating chamber, and the high temperature determination (S61) of the heating chamber is performed in preference to the dead angle determination of the placement position (S64). It is determined that even when it is difficult to detect the temperature of the object 60c by the infrared sensor 52, the total heating time Tz is calculated by the detection result of the weight sensor 25.

亦即是，控制手段23a，在藉由紅外線感測器52之檢測結果來決定總加熱時間Tz之前，當合計之重量W為特定值以下的情況時，係優先移行至少量負載模式，當加熱室溫度TH1為較特定溫度而更高的情況時，係優先移行至高溫模式，當前側左右之重量感測器25的檢測結果之差為較根據合計之重量W與係數所算出的特定值而更大的情況時，係優先移行至死角模式，並藉由重量感測器25之檢測結果來決定總加熱時間Tz。 In other words, when the total weight W is equal to or less than a specific value before the total heating time Tz is determined by the detection result of the infrared sensor 52, the control means 23a preferentially shifts at least the load mode when heating. When the chamber temperature TH1 is higher than the specific temperature, the difference is preferentially shifted to the high temperature mode, and the difference between the detection results of the weight sensors 25 on the left side of the current side is a specific value calculated based on the total weight W and the coefficient. In the larger case, the mode is preferentially shifted to the dead angle mode, and the total heating time Tz is determined by the detection result of the weight sensor 25.

接著，參考圖9，針對一面加熱一面對於正在使用的容器60(杯子和日本酒瓶)作判斷的微波爐加熱1(檢測加熱)作說明。 Next, with reference to Fig. 9, a microwave oven heating 1 (detection heating) for judging the container 60 (cup and Japanese sake bottle) being used will be described.

若是微波爐加熱開始(工程S6)，則接著係 檢測出被加熱物60c之初期溫度Ts1(工程S7)。工程S8~S10，係為對於直到被加熱物60c之溫度Ts3升溫至特定溫度Ts2為止的經過時間ta作測定之工程。若是紅外線感測器52判斷被加熱物60c之溫度係成為與特定溫度Ts2相同，則係前進至下一工程S11。 If the microwave oven starts heating (Engineering S6), then the system is followed. The initial temperature Ts1 of the object 60c to be heated is detected (engineer S7). The items S8 to S10 are the items for measuring the elapsed time ta until the temperature Ts3 of the object to be heated 60c is raised to the specific temperature Ts2. When the infrared sensor 52 determines that the temperature of the object to be heated 60c is the same as the specific temperature Ts2, the process proceeds to the next step S11.

在工程S11中，係求取出從特定溫度Ts2而減去了初期溫度Ts1之後的上升溫度、和從加熱開始起直到到達特定溫度Ts2為止的經過時間ta，並算出升溫速度Tv1。 In the step S11, the rising temperature after the initial temperature Ts1 is subtracted from the specific temperature Ts2 and the elapsed time ta from the start of heating to the specific temperature Ts2 are extracted, and the temperature increase rate Tv1 is calculated.

在工程S12中，係對於所算出的升溫速度Tv1作確認，當其係為較特定之升溫速度Tv0而更慢的情況時，係移行至工程S14之日本酒瓶模式，當係為更快的情況時，係移行至工程S13之杯子模式。 In the item S12, the calculated temperature increase rate Tv1 is confirmed, and when it is slower than the specific temperature increase rate Tv0, the process proceeds to the Japanese bottle mode of the engineering S14, and the system is faster. At the time, the system moves to the cup mode of the project S13.

若是使用日本酒瓶來溫酒，則由於日本酒瓶之高度係為高而壺口係為窄，因此紅外線感測器52係並無法檢測出液面之溫度。故而，紅外線感測器52係成為僅檢測出日本酒瓶之表面的溫度。日本酒瓶之表面的溫度，係為隨著其之中的酒之溫度的上升而起因於熱傳導所上升者，因此，係為升溫速度Tv1會變慢者。 If a Japanese wine bottle is used to warm the wine, since the height of the Japanese wine bottle is high and the mouth of the bottle is narrow, the infrared sensor 52 cannot detect the temperature of the liquid surface. Therefore, the infrared sensor 52 is a temperature at which only the surface of the Japanese wine bottle is detected. The temperature of the surface of the Japanese sake bottle is caused by the increase in the temperature of the wine due to the increase in the temperature of the wine. Therefore, the temperature increase rate Tv1 is slow.

至此為止的加熱，係為微波爐加熱1，之後，係進行在對於正在使用的容器60作了判定之後之微波爐加熱2(追加加熱)。 The heating up to this point is 1 in the microwave oven, and then the microwave oven 2 (additional heating) after the determination of the container 60 being used is performed.
