The inner side of the HC can therefore improve the cleaning performance of the heating chamber HC. The arm member 60 has a top end portion 63 that can be hooked on the supported portion 32 of the net member 30, and is provided (mounted) on the front door 20 so that the net member 30 can be pulled out from the inside of the heating chamber HC by the opening operation of the front door 20. . In the case of this embodiment, the arm member 60 can be configured as a link mechanism including a plate-shaped first part 61 attached to the front door 20 and a plate-shaped second part 62 having a top end. 63, which is rotatably mounted on the first part 61 using a hinge mechanism or the like. The top end portion 63 is composed of, for example, a groove formed in the second portion 62 so as to allow the metal rod constituting the supported portion 32 of the mesh member 30 to pass. By allowing the metal rod of the supported portion 32 of the mesh member 30 to pass through the groove, It can be hooked on the supported portion 32 of the net member 30 . With such a structure, when the user opens the front door 20 , the arm member 60 pulls the net member 30 toward the front side (-Y direction), and as shown in FIG. 5 , the net member 30 can be pulled. Pull it out from the inside of the heating chamber HC. On the other hand, when the user performs the closing operation of the front door 20, the mesh member 30 is pulled inward by the shaft member 40 that is pushed toward the back side of the heating chamber HC by the urging member (spring member). Therefore, as shown in As shown in FIG. 4 , the mesh member 30 can be arranged inside the heating chamber HC.

在本實施形態的烤箱100中，將臂構件60的頂端部63從網構件30的被支承部分32卸下，將網構件30的鉤33從軸構件40卸下，從而如圖3、圖6所示，能夠將網構件30從加熱室HC的內部容易地卸下。另外，在卸下了網構件30的狀態下，如上前述，由於軸構件40藉由彈推構件配置於加熱室HC的裡側，因此能夠容易地清掃例如下側加熱器12b~12c、反射面13c~13e等加熱室HC的內部。也就是說，能够提高加熱室HC的清掃性。 In the oven 100 of this embodiment, the top end portion 63 of the arm member 60 is detached from the supported portion 32 of the mesh member 30, and the hook 33 of the mesh member 30 is detached from the shaft member 40, as shown in FIGS. 3 and 6 As shown, the mesh member 30 can be easily detached from the inside of the heating chamber HC. In addition, with the net member 30 removed, as mentioned above, the shaft member 40 is disposed on the back side of the heating chamber HC by the push member, so that for example, the lower heaters 12b to 12c and the reflective surface can be easily cleaned. 13c~13e etc. are inside the heating chamber HC. In other words, the cleaning performance of the heating chamber HC can be improved.

接下來，參照圖7，說明構成加熱室HC的內表面的反射構件13(反射面13a~13g)的結構例。圖7是本實施形態的烤箱100的剖視圖(YZ剖視圖)，表示前門20關閉的狀態。構成本實施形態的反射構件13的各反射面13a~13g構成 為，為了高效地對加熱對象物進行加熱，能夠將從加熱器12a~12c放射的熱線高效地照射到網構件30上的加熱對象物。 Next, a structural example of the reflective member 13 (reflective surfaces 13a to 13g) constituting the inner surface of the heating chamber HC will be described with reference to FIG. 7 . FIG. 7 is a cross-sectional view (YZ cross-sectional view) of the oven 100 of this embodiment, showing a state in which the front door 20 is closed. Each of the reflective surfaces 13a to 13g constituting the reflective member 13 of this embodiment is composed of This is because, in order to efficiently heat the object to be heated, the heat rays radiated from the heaters 12a to 12c can be efficiently irradiated to the object to be heated on the mesh member 30.

反射面13a(第1反射面)構成加熱室HC的內部的上面(頂面)的一部分。反射面13a配置於上側加熱器12a的上方(+Z方向側)，具有朝向上側加熱器12a凸出的曲面形狀。例如，反射面13a能夠構成為，其側剖面(YZ剖面)具有朝向上側加熱器12a凸出的圓弧形狀。反射面13a的圓弧形狀的曲率半徑可以處於2cm~10cm的範圍內，理想是可以處於4cm~8cm的範圍內，更理想是可以處於5~7cm的範圍內。在本實施形態的烤箱100中，反射面13a的圓弧形狀的曲率半徑為6.07cm±0.2cm。另外，反射面13a與上側加熱器12a的間隔G可以處於0.2cm~1cm的範圍內，理想是處於0.3~0.8cm的範圍內，更優選可以處於0.4~0.6cm的範圍內。在本實施形態的烤箱100中，反射面13a與上側加熱器12a的間隔G為0.54cm±0.02cm。藉由像這樣構成及配置反射面13a，能夠將從上側加熱器12a朝向上方放射的熱線大範圍地反射，能夠降低網構件30上的加熱對象物(例如烤麵包)的燒烤不均。 The reflective surface 13a (first reflective surface) constitutes a part of the upper surface (ceiling surface) inside the heating chamber HC. The reflective surface 13a is disposed above the upper heater 12a (+Z direction side) and has a curved surface shape convex toward the upper heater 12a. For example, the reflective surface 13a can be configured so that its side cross section (YZ cross section) has an arc shape that protrudes toward the upper heater 12a. The radius of curvature of the arc shape of the reflective surface 13a may be in the range of 2 cm to 10 cm, ideally in the range of 4 cm to 8 cm, and more preferably in the range of 5 to 7 cm. In the oven 100 of this embodiment, the radius of curvature of the arc shape of the reflective surface 13a is 6.07 cm±0.2 cm. In addition, the distance G between the reflective surface 13a and the upper heater 12a may be in the range of 0.2 cm to 1 cm, preferably in the range of 0.3 to 0.8 cm, and more preferably in the range of 0.4 to 0.6 cm. In the oven 100 of this embodiment, the distance G between the reflective surface 13a and the upper heater 12a is 0.54 cm±0.02 cm. By configuring and arranging the reflective surface 13a in this way, the heat rays radiated upward from the upper heater 12a can be reflected over a wide range, thereby reducing uneven grilling of the object to be heated (for example, toast) on the mesh member 30.

反射面13b(第2反射面)構成加熱室HC的內部的上面(頂面)的一部分。在本實施形態的情況下，反射面13b具有平面形狀，配置於上側加熱器12a的前方(-Y方向側)。反射面13b也可以構成為與反射面13a(第1反射面)的前端(-Y方向側的端部)連續的面。另外，反射面13b以朝向網構件30上的加熱對象物反射從上側加熱器12a)放射的熱線的方式相對於水平面傾斜。反射面13b相對於水平面的傾角θ 1優選可以處於15.4度±5度的範圍內，更優選可以處於15.4度±1度的範圍內。藉由像這樣構成反射面13b，能夠將從上側加熱器12a放射的熱線高效地照射到網構件30上的加熱對象物。在此，在本實施形態中，“水平面”能夠定義為在網構件30(載置部分31)載置加熱對象物的面(載置面)。 反射面13c(第3反射面)構成加熱室HC的內部的下表面(底面)的一部分。在本實施形態的情況下，反射面13c具有平面形狀，配置於下側加熱器12b~12c的前方(-Y方向側)。另外，反射面13c以朝向網構件30上的加熱對象物反射從下側加熱器12b~12c(尤其是是12b)放射的熱線的方式相對於水平面傾斜。反射面13c相對於水平面的傾角θ 2理想是可以處於54.5度±5度的範圍內，更理想是可以處於54.5度±1度的範圍內。藉由像這樣構成反射面13c，能夠將從下側加熱器12b~12c放射的熱線高效地照射到網構件30上的加熱對象物。 反射面13d(第5反射面)構成加熱室HC的內部的下表面(底面)的一部分。反射面13d配置於下側加熱器12b~12c的下方(-Z方向側)。對反射面13d實施用於使從加熱器12a~12c(尤其是是下側加熱器12b~12c)放射的熱線漫反射的加工，在本實施形態的情況下，作為該加工，形成四稜錐狀的複數個突起(凸部)。藉由對反射面13d實施這樣的加工，能夠使加熱室HC的內部的熱線的分佈均勻化，將該熱線均勻且高效地照射到網構件30上的加熱對象物。 在此，反射面13d也可以構成為以能夠卸下(能夠裝卸)的方式設於主體部10的下部的托盤14的一部分的面。圖8~圖9表示具有反射面13d的托盤14的結構例。圖8是烤箱100整體的正面立體圖，表示從烤箱100拉出了托盤14的狀態。另外，圖9是烤箱100的剖視立體圖(YZ剖面的立體圖)，將從烤箱100拉出托盤14的情形經時地(階段性地)表示為圖9的(a)~(c)。 托盤14是為了接受來自載置於網構件30上的加熱對象物的落下物(例如麵包屑)而構成加熱室HC的下表面(底面)的一部分的構件，以能夠裝卸的方式配置於主體部10的下部。托盤14具有在從烤箱100將托盤14拉出時供使用者把持的把持部14a和用於接受來自網構件30上的加熱對象物的落下物的接受容納部14b(接受盤部)。藉由將這樣的托盤14設於烤箱100，使用者能夠如圖9的(a)~(c)經時地表示的那樣，一邊對把持部14a進行把持一邊將托盤14從烤箱100拉出，從而容易地進行來自加熱對象物的落下物的清掃。另外，托盤14的接受容納部14b在托盤14被配置(安裝)於烤箱100的下部的狀態(圖9的(a)的狀態)下，構成加熱室HC的下表面(底面)的一部分，並作為漫反射從加熱器12a~12c(尤其是是下側加熱器12b~12c)放射的熱線的反射面13d發揮功能。在本實施形態的情況下，在托盤14的接受容納部14b(反射面13d)形成有用於使從加熱器12a~ 12c(尤其是是下側加熱器12b~12c)放射的熱線漫反射的四稜錐狀的複數個突起(凸部)。 當由複數個突起構成作為加熱室HC的下表面的反射面13d時，來自加熱對象物的落下物蓄積(堆積)，反射效率容易降低，並且，使用者從主體部10的前面的開放部將手伸入對該反射面13d進行清掃是繁雜的。因此，如本實施形態這樣，藉由將托盤14的一部分(接受容納部14b)構成為反射面13d，能夠使該反射面13d的清掃變得容易。 回到圖7，反射面13e(第4反射面)構成加熱室HC的內部的裡面的一部分。在本實施形態的情況下，反射面13e具有平面形狀，配置於下側加熱器12b~12c的後方(+Y方向側(裡側))。另外，反射面13e以朝向網構件30上的加熱對象物反射從下側加熱器12b~12c(尤其是是12c)放射的熱線的方式相對於水平面傾斜。反射面13e相對於水平面的傾角θ 3理想是可以處於56.2度±5度的範圍內，更優選可以處於56.2度±1度的範圍內。藉由這樣構成反射面13e，能夠將從下側加熱器12b~12c放射的熱線高效地照射到網構件30上的加熱對象物。 反射面13f(第6反射面)構成加熱室HC的內部的裡面的一部分。反射面13f配置於前後方向(Y軸方向)上的加熱器12a~12c的裡側且是上下方向(Z軸方向)上的上側加熱器12a與下側加熱器12b~12c之間。反射面13f能夠是與反射面13e(第4反射面)的上側(+Z方向側)連續的面。另外，對反射面13f實施用於使從加熱器12b~12c放射的熱線漫反射的加工，在本實施形態的情況下，作為該加工形成有四稜錐狀的複數個突起(凸部)。 另外，反射面13g(第7反射面)構成加熱室HC的內部的裡面的一部分。在本實施形態的情況下，反射面13g具有平面形狀，配置於上側加熱器12a的裡側(+Y方向側)。反射面13g也可以構成為與反射面13a(第1反射面)和反射面13f(第6反射面)連續的面。另外，反射面13g以朝向網構件30上的加熱對象物反射從上側加熱器12a放射的熱線的方式相對於水平面傾斜。反射面13g相對於水平面的傾角θ 4優選可以處於47.4度±5度的範圍內，更理想是可以處於47.4度±1度的範圍內。藉由這樣構成反射面13g，能夠將從上側加熱器12a放射的熱線高效地照射到網構件30上的加熱對象物。 圖10示意性地表示從各加熱器12a~12c放射的熱線Rd在各反射面(反射面13a~13c、13e、13g)被反射而對網構件30上的加熱對象物照射的情形(即，在加熱室HC的內部的熱線分佈)。此外，對於以將熱線漫反射的方式構成的反射面13d、13f，若考慮反射面13d、13f處的漫反射則圖會變得複雜，因此在圖10中，省略反射面13d、13f處的熱線的反射的圖示。從圖10可知，利用反射構件13(反射面13a~13c、13e、13g)的上述結構，能夠將從各加熱器12a~12c放射的熱線Rd高效地照射到網構件30上的加熱對象物。另外，若考慮反射面13d、13f處的熱線Rd的漫反射，則應能理解，加熱室HC的內部的熱線Rd的分佈更加均勻化，熱線Rd更加均勻且高效地照射到網構件30上的加熱對象物。即，根據本實施形態的烤箱100的上述結構，能夠均勻且高效地加熱網構件30上的加熱對象物。 ＜第2實施形態＞ 在第2實施形態中，參照圖11~圖12，說明將用於在加熱室HC的內部使空氣(熱)對流的對流機構設於烤箱100的例子。此外，本實施形態基本上承繼第1實施形態，設於加熱室HC的內部的複數個加熱器12和反射構件13(反射面13a~13g)等的結構如在第1實施形態中說明的那樣。 圖11的(a)是具有作為對流機構的風扇機構70的烤箱100的剖視圖(YZ剖視圖)，圖11的(b)表示風扇機構70的對流風扇71的結構例。圖11的(a)~圖11的(b)中的空心箭頭表示空氣的流動。例如如圖11的(a)所示，本實施形態的烤箱100作為對流機構能夠具備風扇機構70，該風扇機構70用於經由設於加熱室HC的反射面13g的複數個孔從加熱室HC的內部引入空氣，將引入的空氣向加熱室HC的內部供給(放出)。風扇機構70能夠具備對流風扇71和使對流風扇71旋轉驅動的馬達72。在圖11的(b)中表示對流風扇71的結構例。圖11的(b)中的單點劃線表示對流風扇71的旋轉軸(也可以理解為馬達72的旋轉軸)。如圖11的(b)的空心箭頭所示，本實施形態的對流風扇71能夠構成為，藉由馬達72的旋轉驅動將從旋轉軸方向引入的空氣向半徑方向放出。 另外，本實施形態的風扇機構70能夠配置為，對流風扇71的旋轉軸相對於反射面13g的角度收斂於90度±5度(優選為90度±1度)的範圍。具體而言，如前前述，反射面13g相對於水平面以傾角θ 4傾斜，因此風扇機構70能夠配置為，對流風扇71的旋轉軸相對於水平面的傾角θ 5收斂於42.6度±5度的範圍內(理想為42.6度±1度的範圍內)。根據該結構，風扇機構70能夠將對流風扇71的旋轉軸相對於反射面13g大致垂直地配置，因此藉由對流風扇71的旋轉驅動，能夠經由後述的反射面13g的複數個第1孔15a高效地引入加熱室HC內的空氣。 圖12是從前方觀察前門20打開的狀態下的烤箱100的圖(正面圖)，表示由風扇機構70進行的加熱室HC內的空氣的對流。圖12中的空心箭頭表示空氣的流動。如圖12所示，在反射面13g形成有用於供風扇機構70引入加熱室HC內的空氣的複數個第1孔15a和用於向加熱室HC內供給(放出)空氣的複數個第2孔15b。在圖12所示的例子中，在反射面13g，複數個第1孔15a形成於左右方向(X軸方向)上的中央部，複數個第2孔15b形成於左右方向(X軸方向)上的複數個第1孔15a的周圍(+X方向側，-X方向側)。另外，風扇機構70配置於反射面13g的複數個第1孔15a的裡側(+Y方向側)。在這樣的結構中，能夠將利用風扇機構70經由複數個第1孔15a從加熱室HC內引入的氣體經由複數個第2孔15b向加熱室HC內供給，在加熱室HC的內部使空氣(熱)對流。即，能夠使加熱室HC內的溫度分佈均勻化。 在此，利用對流風扇71從加熱室HC內引入的空氣暫時滯留在烤箱100的內部(具體而言，烤箱100的外殼與反射構件13之間的空間)，因此有時在烤箱100的內部蓄積熱。在本實施形態的烤箱100中，在主體部10的外殼的上面形成有開口10a(參照圖1~圖3、圖11)，烤箱100的內部的空氣(即，熱)經由該開口10a向外部排出。由此，能夠避免烤箱100本身的溫度變得過高，並且，能夠進行風扇機構70的馬達72的冷卻。 另外，風扇機構70也可以具備用於冷卻馬達72的冷卻風扇73。冷卻風扇73能夠安裝於被馬達72旋轉驅動的旋轉軸的與安裝有對流風扇71的端部相反的一側的端部。換言之，對流風扇71和冷卻風扇73以夾入馬達72的方式安裝於同一旋轉軸。 而且，烤箱100也可以以在加熱室HC的內部使熱對流的方式進行各加熱器12a~12c的藉由控制。該通電控制能夠由設於烤箱100的控制部(未圖示)進行。控制部例如具有CPU、記憶體等，能夠根據來自操作部24的使用者的操作指示對烤箱100的各單元進行控制。例如，控制部通過每隔預定的時間依次切換複數個加熱器12a~12c中的進行通電(點亮)的1個加熱器，能夠在加熱室HC的內部使空氣(熱)對流。作為一例，控制部在僅對上側加熱器12a通電並經過預定的時間後，停止上側加熱器12a的通電，僅對下側加熱器12b通電，在經過預定的時間之後，停止下側加熱器12b的通電，僅對下側加熱器12c通電。然後，在經過預定的時間之後，停止下側加熱器12c的通電，僅對上側加熱器12a通電。藉由反復進行這樣的控制(處理)，能夠在加熱室HC的內部使空氣(熱)對流。 ＜第3實施方式＞ 在第3實施形態中，說明能夠對網構件30上的加熱對象物更均勻地照射熱線的加熱器12(各加熱器12a~12c)的結構例。圖13示意性地表示本實施形態的加熱器12的結構例。本實施形態的加熱器12是具備包含碳(碳纖維)的電熱絲81、覆蓋電熱絲81的玻璃管82以及設於玻璃管82的兩端的端子部83的碳加熱器。電熱絲81是捲繞成螺旋狀，藉由通電而發熱(即，放射熱線)的構件。另外，端子部83密閉玻璃管82，並且能夠作為與電熱絲81的端部連接的電極發揮功能。經由設於玻璃管82的兩側的端子部83向電熱絲81供電，能夠利用電熱絲81的電阻從電熱絲81放射熱(熱線)。 在烤箱100中，存在熱線容易集中於加熱室HC的內部的中央部(例如，配置於加熱室HC內的網構件30的中央部)的傾向。因此，如圖13所示，本實施形態的加熱器12能夠包括以第1密度捲繞電熱絲81的中央區域R 1和在中央區域R 1的周邊(+X方向側，-X方向側)以第2密度捲繞電熱絲81的周邊區域R 2。而且，中央區域R 1的電熱絲81的第1密度比周邊區域R 2的電熱絲81的第2密度小。由此，緩和熱線向加熱室HC的中央部的集中，謀求向網構件30上的加熱對象物照射的熱線的均勻化。此外，電熱絲81的密度也可以理解為每單位長度的電熱絲81的匝數和/或電熱絲81的間距。 在此，加熱器12能夠構成為，在左右方向(X軸方向)上，中央區域R 1的長度為一個周邊區域R 2的長度以上。例如，中央區域R 1的長度也可以為一個周邊區域R 2的長度的1.5倍以上，或者2倍以上。另外，加熱器12能夠構成為，中央區域R 1的電熱絲81的第1密度為周邊區域R 2的電熱絲81的第2密度的3/4以下。例如，第1密度能夠在第2密度的1/4~3/4的範圍內，理想在第2密度的1/3~2/3的範圍內。在本實施形態的加熱器12的結構例中，第1密度為第2密度的1/2。此外，上述的加熱器12的結構也可以應用於複數個加熱器12a~12c的全部，但不限於此，也可以應用於複數個加熱器12a~12c中的至少1個(例如上側加熱器12a)。 發明不限於上述實施形態，能夠在不脫離發明的精神和範圍的前提下進行各種各樣的變更和變形。 The reflective surface 13b (second reflective surface) constitutes a part of the upper surface (ceiling surface) inside the heating chamber HC. In the case of this embodiment, the reflective surface 13b has a planar shape and is arranged in front of the upper heater 12a (on the −Y direction side). The reflective surface 13b may be configured as a surface continuous with the front end (the end on the −Y direction side) of the reflective surface 13a (first reflective surface). In addition, the reflective surface 13b is inclined with respect to the horizontal plane so as to reflect the heat radiation radiated from the upper heater 12a) toward the heating object on the mesh member 30. The inclination angle θ 1 of the reflective surface 13 b with respect to the horizontal plane is preferably within the range of 15.4 degrees ± 5 degrees, and more preferably within the range of 15.4 degrees ± 1 degrees. By configuring the reflective surface 13b in this way, the heated object on the mesh member 30 can be efficiently irradiated with the heat ray radiated from the upper heater 12a. Here, in this embodiment, the "horizontal surface" can be defined as the surface (placement surface) on which the object to be heated is placed on the net member 30 (placement portion 31). The reflective surface 13c (third reflective surface) constitutes a part of the lower surface (bottom surface) inside the heating chamber HC. In the case of this embodiment, the reflective surface 13c has a planar shape and is arranged in front of the lower heaters 12b to 12c (-Y direction side). In addition, the reflective surface 13c is inclined with respect to the horizontal plane so as to reflect the heat rays radiated from the lower heaters 12b to 12c (particularly 12b) toward the heating object on the mesh member 30. The inclination angle θ 2 of the reflecting surface 13 c with respect to the horizontal plane can ideally be in the range of 54.5 degrees ± 5 degrees, and more ideally can be in the range of 54.5 degrees ± 1 degree. By configuring the reflective surface 13c in this way, the heating object on the mesh member 30 can be efficiently irradiated with the heat rays radiated from the lower heaters 12b to 12c. The reflective surface 13d (fifth reflective surface) constitutes a part of the lower surface (bottom surface) inside the heating chamber HC. The reflective surface 13d is arranged below the lower heaters 12b to 12c (-Z direction side). The reflective surface 13d is processed to diffusely reflect the heat rays radiated from the heaters 12a to 12c (especially the lower heaters 12b to 12c). In this embodiment, a square pyramid is formed as this processing. A plurality of protrusions (convex parts). By subjecting the reflective surface 13d to such processing, the distribution of the heat rays inside the heating chamber HC can be made uniform, and the heat rays can be uniformly and efficiently irradiated to the heating target object on the mesh member 30 . Here, the reflective surface 13d may be configured as a surface of a part of the tray 14 provided in a detachable (detachable) manner at the lower part of the main body 10. 8 to 9 show a structural example of the tray 14 having the reflective surface 13d. FIG. 8 is a front perspective view of the entire oven 100 , showing a state in which the tray 14 is pulled out from the oven 100 . 9 is a cross-sectional perspective view of the oven 100 (a perspective view of the YZ cross section), and the state of pulling out the tray 14 from the oven 100 is shown as (a) to (c) in FIG. 9 over time (in stages). The tray 14 is a member that constitutes a part of the lower surface (bottom surface) of the heating chamber HC in order to receive falling objects (for example, bread crumbs) from the object to be heated placed on the mesh member 30, and is detachably arranged on the main body. The lower part of 10. The tray 14 has a holding portion 14 a for the user to hold when pulling the tray 14 out of the oven 100 , and a receiving and accommodating portion 14 b (receiving tray portion) for receiving dropped objects from the heating target object on the net member 30 . By disposing such a tray 14 in the oven 100, the user can pull the tray 14 out of the oven 100 while holding the holding portion 14a, as shown temporally in (a) to (c) of Fig. 9 . This makes it easy to clean up fallen objects from the object to be heated. In addition, the receiving portion 14b of the tray 14 constitutes a part of the lower surface (bottom surface) of the heating chamber HC when the tray 14 is arranged (mounted) in the lower part of the oven 100 (the state of FIG. 9(a)), and It functions as the reflective surface 13d which diffusely reflects the heat radiation radiated from the heaters 12a-12c (particularly, the lower heaters 12b-12c). In the case of this embodiment, the receiving part 14b (reflective surface 13d) of the tray 14 is formed with four heat rays for diffusely reflecting the heat rays radiated from the heaters 12a to 12c (especially the lower heaters 12b to 12c). Plural pyramid-shaped protrusions (convex portions). When the reflective surface 13d as the lower surface of the heating chamber HC is composed of a plurality of protrusions, falling objects from the heating object accumulate (accumulate), and the reflection efficiency is likely to decrease. Furthermore, the user can move the reflective surface 13d from the front opening of the main body 10. It is complicated to reach in and clean the reflective surface 13d. Therefore, as in this embodiment, by configuring a part of the tray 14 (receiving and accommodating portion 14b) as the reflective surface 13d, cleaning of the reflective surface 13d can be facilitated. Returning to FIG. 7 , the reflective surface 13e (the fourth reflective surface) constitutes a part of the back surface of the heating chamber HC. In the case of this embodiment, the reflective surface 13e has a planar shape and is arranged behind the lower heaters 12b to 12c (+Y direction side (backside)). In addition, the reflective surface 13e is inclined with respect to the horizontal plane so as to reflect the heat rays radiated from the lower heaters 12b to 12c (particularly 12c) toward the heating object on the mesh member 30. The inclination angle θ 3 of the reflective surface 13 e with respect to the horizontal plane can ideally be in the range of 56.2 degrees ± 5 degrees, and more preferably can be in the range of 56.2 degrees ± 1 degrees. By configuring the reflective surface 13e in this way, the heated object on the mesh member 30 can be efficiently irradiated with the heat rays radiated from the lower heaters 12b to 12c. The reflective surface 13f (sixth reflective surface) constitutes a part of the back surface of the heating chamber HC. The reflective surface 13f is disposed behind the heaters 12a to 12c in the front-rear direction (Y-axis direction) and between the upper heater 12a and the lower heaters 12b-12c in the up-down direction (Z-axis direction). The reflective surface 13f may be a surface continuous with the upper side (+Z direction side) of the reflective surface 13e (the fourth reflective surface). In addition, the reflective surface 13f is processed to diffusely reflect the heat rays radiated from the heaters 12b to 12c. In this embodiment, a plurality of square pyramid-shaped protrusions (convex portions) are formed as a result of this processing. In addition, the reflective surface 13g (the seventh reflective surface) constitutes a part of the back surface of the heating chamber HC. In the case of this embodiment, the reflective surface 13g has a planar shape and is arranged on the back side (+Y direction side) of the upper heater 12a. The reflective surface 13g may be configured as a surface continuous with the reflective surface 13a (first reflective surface) and the reflective surface 13f (sixth reflective surface). In addition, the reflective surface 13g is inclined with respect to the horizontal plane so as to reflect the heat radiation radiated from the upper heater 12a toward the heating object on the mesh member 30. The inclination angle θ 4 of the reflecting surface 13 g with respect to the horizontal plane is preferably within the range of 47.4 degrees ± 5 degrees, and more preferably, it can be within the range of 47.4 degrees ± 1 degree. By configuring the reflective surface 13g in this way, the heated object on the mesh member 30 can be efficiently irradiated with the heat ray radiated from the upper heater 12a. FIG. 10 schematically shows a state in which the heat rays Rd radiated from the respective heaters 12a to 12c are reflected on the respective reflecting surfaces (reflecting surfaces 13a to 13c, 13e, and 13g) and are irradiated to the heating target object on the mesh member 30 (i.e., Distribution of hot wires inside the heating chamber HC). In addition, regarding the reflective surfaces 13d and 13f configured to diffusely reflect the heat rays, the diagram becomes complicated if the diffuse reflection at the reflective surfaces 13d and 13f is taken into account. Therefore, in FIG. 10 , the reflective surfaces 13d and 13f are omitted. Illustration of reflection of hot heat. As can be seen from FIG. 10 , the above-mentioned structure of the reflective member 13 (reflective surfaces 13a to 13c, 13e, and 13g) can efficiently irradiate the heating object on the mesh member 30 with the heat radiation Rd radiated from the heaters 12a to 12c. In addition, if the diffuse reflection of the heat ray Rd at the reflective surfaces 13d and 13f is taken into consideration, it can be understood that the distribution of the heat ray Rd inside the heating chamber HC becomes more uniform, and the heat ray Rd irradiates the mesh member 30 more uniformly and efficiently. Heating object. That is, according to the above-mentioned structure of the oven 100 of this embodiment, the object to be heated on the mesh member 30 can be heated uniformly and efficiently. <Second Embodiment> In the second embodiment, an example in which a convection mechanism for convection of air (heat) inside the heating chamber HC is provided in the oven 100 will be described with reference to FIGS. 11 and 12 . In addition, this embodiment basically succeeds the first embodiment, and the structures of the plurality of heaters 12 and the reflection members 13 (reflection surfaces 13a to 13g) provided inside the heating chamber HC are as described in the first embodiment. . (a) of FIG. 11 is a cross-sectional view (YZ cross-sectional view) of the oven 100 having the fan mechanism 70 as a convection mechanism, and (b) of FIG. 11 shows a structural example of the convection fan 71 of the fan mechanism 70. The hollow arrows in Figure 11(a) to Figure 11(b) indicate the flow of air. For example, as shown in FIG. 11(a) , the oven 100 of this embodiment can be provided with a fan mechanism 70 as a convection mechanism for transmitting water from the heating chamber HC through a plurality of holes provided on the reflective surface 13g of the heating chamber HC. Air is introduced into the inside of the heating chamber HC and the introduced air is supplied (released) to the inside of the heating chamber HC. The fan mechanism 70 can include a convection fan 71 and a motor 72 that drives the convection fan 71 to rotate. A structural example of the convection fan 71 is shown in (b) of FIG. 11 . The one-dot chain line in FIG. 11(b) represents the rotation axis of the convection fan 71 (it can also be understood as the rotation axis of the motor 72). As shown by the hollow arrow in FIG. 11(b) , the convection fan 71 of this embodiment can be configured to discharge the air introduced from the direction of the rotation axis in the radial direction by the rotational driving of the motor 72 . In addition, the fan mechanism 70 of this embodiment can be arranged so that the angle of the rotation axis of the convection fan 71 with respect to the reflecting surface 13g is within the range of 90 degrees ±5 degrees (preferably 90 degrees ±1 degrees). Specifically, as mentioned above, the reflection surface 13g is inclined at the inclination angle θ 4 with respect to the horizontal plane. Therefore, the fan mechanism 70 can be arranged so that the inclination angle θ 5 of the rotation axis of the convection fan 71 with respect to the horizontal plane converges in the range of 42.6 degrees ± 5 degrees. Within (ideally within the range of 42.6 degrees ±1 degrees). According to this structure, the fan mechanism 70 can arrange the rotation axis of the convection fan 71 substantially vertically with respect to the reflection surface 13g. Therefore, by rotationally driving the convection fan 71, it is possible to efficiently pass through the plurality of first holes 15a of the reflection surface 13g to be described later. Ground air is introduced into the heating chamber HC. FIG. 12 is a view (front view) of the oven 100 with the front door 20 open when viewed from the front, and shows the convection of air in the heating chamber HC by the fan mechanism 70 . The hollow arrows in Figure 12 indicate the flow of air. As shown in FIG. 12 , a plurality of first holes 15 a for the fan mechanism 70 to introduce air into the heating chamber HC and a plurality of second holes for supplying (releasing) air into the heating chamber HC are formed on the reflective surface 13 g. 15b. In the example shown in FIG. 12 , in the reflective surface 13 g, a plurality of first holes 15 a are formed in the center portion in the left-right direction (X-axis direction), and a plurality of second holes 15 b are formed in the left-right direction (X-axis direction). around the plurality of first holes 15a (+X direction side, -X direction side). In addition, the fan mechanism 70 is arranged on the back side (+Y direction side) of the plurality of first holes 15a of the reflecting surface 13g. In such a structure, the gas introduced from the heating chamber HC through the plurality of first holes 15a by the fan mechanism 70 can be supplied into the heating chamber HC through the plurality of second holes 15b, and the air ( heat) convection. That is, the temperature distribution in the heating chamber HC can be made uniform. Here, the air introduced from the heating chamber HC by the convection fan 71 temporarily remains inside the oven 100 (specifically, the space between the outer shell of the oven 100 and the reflecting member 13), and therefore may accumulate inside the oven 100. hot. In the oven 100 of this embodiment, an opening 10a is formed on the upper surface of the shell of the main body 10 (see FIGS. 1 to 3 and 11 ), and the air (that is, heat) inside the oven 100 is vented to the outside through the opening 10a. discharge. Thereby, it is possible to prevent the temperature of the oven 100 itself from becoming too high and to cool the motor 72 of the fan mechanism 70 . In addition, the fan mechanism 70 may include a cooling fan 73 for cooling the motor 72 . The cooling fan 73 can be mounted on the end of the rotation shaft that is rotationally driven by the motor 72 on the opposite side to the end where the convection fan 71 is mounted. In other words, the convection fan 71 and the cooling fan 73 are installed on the same rotating shaft with the motor 72 sandwiched between them. Furthermore, the oven 100 may control the circulation of each of the heaters 12a to 12c so as to cause heat convection in the heating chamber HC. This energization control can be performed by a control unit (not shown) provided in the oven 100 . The control unit has, for example, a CPU, a memory, etc., and can control each unit of the oven 100 based on the user's operation instructions from the operation unit 24 . For example, the control unit can convect air (heat) inside the heating chamber HC by sequentially switching one of the plurality of heaters 12 a to 12 c that is energized (lit) every predetermined time. As an example, the control unit energizes only the upper heater 12a and stops the energization of the upper heater 12a after a predetermined time has elapsed, energizes only the lower heater 12b, and stops the lower heater 12b after a predetermined time has elapsed. , only the lower heater 12c is energized. Then, after a predetermined time has elapsed, the energization of the lower heater 12c is stopped, and only the upper heater 12a is energized. By repeating such control (processing), air (heat) can be convected inside the heating chamber HC. <Third Embodiment> In the third embodiment, a structural example of the heater 12 (each heater 12a to 12c) that can irradiate the heating object on the mesh member 30 with hot heat more uniformly will be described. FIG. 13 schematically shows a structural example of the heater 12 of this embodiment. The heater 12 of this embodiment is a carbon heater including a heating wire 81 made of carbon (carbon fiber), a glass tube 82 covering the heating wire 81 , and terminal portions 83 provided at both ends of the glass tube 82 . The heating wire 81 is wound in a spiral shape and generates heat (that is, radiates heat) when electricity is applied. In addition, the terminal portion 83 can seal the glass tube 82 and function as an electrode connected to the end portion of the heating wire 81 . Electric power is supplied to the heating wire 81 via the terminal portions 83 provided on both sides of the glass tube 82 , and heat (heat wire) can be radiated from the heating wire 81 by utilizing the resistance of the heating wire 81 . In the oven 100, there is a tendency that the heat rays tend to be concentrated in the central portion inside the heating chamber HC (for example, the central portion of the mesh member 30 arranged in the heating chamber HC). Therefore, as shown in FIG. 13 , the heater 12 of this embodiment can include a central region R 1 in which the electric heating wire 81 is wound with a first density and the periphery (+X direction side, −X direction side) of the central region R 1 The peripheral area R 2 of the heating wire 81 is wound at the second density. Furthermore, the first density of the heating wires 81 in the central region R 1 is smaller than the second density of the heating wires 81 in the peripheral region R 2 . Thereby, the concentration of the heat rays in the central part of the heating chamber HC is alleviated, and the heat rays irradiated to the heating object on the mesh member 30 are made uniform. In addition, the density of the electric heating wire 81 can also be understood as the number of turns of the electric heating wire 81 per unit length and/or the spacing of the electric heating wire 81 . Here, the heater 12 can be configured such that the length of the central region R 1 is equal to or longer than the length of one peripheral region R 2 in the left-right direction (X-axis direction). For example, the length of the central region R 1 may be more than 1.5 times, or more than 2 times the length of one peripheral region R 2 . In addition, the heater 12 can be configured such that the first density of the heating wires 81 in the central region R 1 is 3/4 or less of the second density of the heating wires 81 in the peripheral region R 2 . For example, the first density can be in the range of 1/4 to 3/4 of the second density, and ideally can be in the range of 1/3 to 2/3 of the second density. In the structural example of the heater 12 of this embodiment, the first density is 1/2 of the second density. In addition, the structure of the heater 12 described above can also be applied to all of the plurality of heaters 12a to 12c, but is not limited thereto and can also be applied to at least one of the plurality of heaters 12a to 12c (for example, the upper heater 12a ). The invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the spirit and scope of the invention.
