The communication device 40 communicates with an external device through, for example, a wireless LAN.

風扇殼體19是配置於外框13之後面，以覆蓋基板15及風扇17之後方。在風扇殼體19與風扇殼體19之前方的基板15之間的空間中，形成有第1風路。第1風路29是從風扇17至基板15的風路。亦即，風扇殼體19之一部分形成第1風路29。The fan housing 19 is arranged on the rear of the outer frame 13 to cover the base 15 and the rear of the fan 17. A first air passage is formed in the space between the fan case 19 and the base plate 15 in front of the fan case 19. The first air passage 29 is an air passage from the fan 17 to the base plate 15. That is, a part of the fan case 19 forms the first air passage 29.

在風扇殼體19與風扇殼體19之後方的第1金屬板21之間的空間中，形成有第2風路31。第2風路31是從風扇17至通訊裝置40與電波洩漏防止板25之間的空間的風路。亦即，風扇殼體19之另外一部分形成第2風路31。A second air passage 31 is formed in the space between the fan case 19 and the first metal plate 21 behind the fan case 19. The second air passage 31 is an air passage from the fan 17 to the space between the communication device 40 and the electric wave leakage prevention plate 25. That is, the other part of the fan case 19 forms the second air passage 31.

第1金屬板21是夾著風扇殼體19而配置於基板15之後方，並將來自加熱室5之熱隔熱。第2金屬板23是配置成覆蓋第1金屬板21之後面，並將來自加熱室5之熱隔熱。The first metal plate 21 is arranged behind the base plate 15 with the fan case 19 interposed therebetween, and insulates the heat from the heating chamber 5. The second metal plate 23 is arranged to cover the rear surface of the first metal plate 21 and insulate the heat from the heating chamber 5.

電波洩漏防止板25是用以防止電波從加熱室5之內部通過門7朝外部洩漏之金屬製的板。電波洩漏防止板25是安裝於外框13之後面以覆蓋第2金屬板23之後面。內框27是與外框13一起保持電波洩漏防止板25。The electric wave leakage prevention plate 25 is a metal plate for preventing electric waves from leaking from the inside of the heating chamber 5 through the door 7 to the outside. The radio wave leakage prevention plate 25 is attached to the rear surface of the outer frame 13 to cover the rear surface of the second metal plate 23. The inner frame 27 holds the radio wave leakage prevention plate 25 together with the outer frame 13.

圖4是將門7的外框13拆卸後的狀態下的加熱調理器1的前方立體圖。如圖4所示，電波洩漏防止板25是配置於與加熱室5的開口緊鄰之外側。因此，當加熱室5之內部被加熱而成為高溫時，電波洩漏防止板25也會成為高溫。4 is a front perspective view of the heating conditioner 1 in a state where the outer frame 13 of the door 7 is removed. As shown in FIG. 4, the radio wave leakage prevention plate 25 is arranged immediately outside the opening of the heating chamber 5. Therefore, when the inside of the heating chamber 5 is heated and becomes high temperature, the electric wave leakage prevention plate 25 also becomes high temperature.

如圖3所示，通訊裝置40是位於外框13之下部，亦即電波洩漏防止板25之下部的附近。因此，加熱調理器1必須作成為用以將電波洩漏防止板25與通訊裝置40之間斷熱，並且將通訊裝置40冷卻的構成。即便電波洩漏防止板25因加熱室5之內部之熱而成為高溫，該構成仍可防止通訊裝置40的溫度超過動作溫度範圍。As shown in FIG. 3, the communication device 40 is located at the lower part of the outer frame 13, that is, near the lower part of the radio wave leakage prevention plate 25. Therefore, the heating conditioner 1 must be configured to cut off the heat between the radio wave leakage prevention plate 25 and the communication device 40, and to cool the communication device 40. Even if the radio wave leakage prevention plate 25 becomes high temperature due to the heat inside the heating chamber 5, this configuration can still prevent the temperature of the communication device 40 from exceeding the operating temperature range.

圖5是將內框27及電波洩漏防止板25拆卸後的狀態下的門7之一部分的後方立體圖。如圖3及圖5所示，外框13之左側配置有第2金屬板23。第2金屬板23位於基板15之後方，並且在前後方向上配置於加熱室5與第1金屬板21之間。FIG. 5 is a rear perspective view of a part of the door 7 in a state where the inner frame 27 and the radio wave leakage prevention plate 25 are removed. As shown in FIGS. 3 and 5, the second metal plate 23 is arranged on the left side of the outer frame 13. The second metal plate 23 is located behind the substrate 15 and is arranged between the heating chamber 5 and the first metal plate 21 in the front-rear direction.

圖6是從圖5所示的狀態更進一步地將第2金屬板23拆卸後的狀態下的門7之一部分的後方立體圖。如圖3及圖6所示，第1金屬板21位於基板15之後方，並且在前後方向上配置於第2金屬板23與風扇殼體19之間。FIG. 6 is a rear perspective view of a part of the door 7 in a state where the second metal plate 23 is further removed from the state shown in FIG. 5. As shown in FIGS. 3 and 6, the first metal plate 21 is located behind the substrate 15 and is arranged between the second metal plate 23 and the fan case 19 in the front-rear direction.

圖7是從圖6所示的狀態更進一步地將第1金屬板21拆卸後的狀態下的門7之一部分的後方立體圖。如圖3及圖7所示，風扇殼體19位於基板15之後方，並且在前後方向上配置於基板15與第1金屬板21之間。FIG. 7 is a rear perspective view of a part of the door 7 in a state where the first metal plate 21 is further removed from the state shown in FIG. 6. As shown in FIGS. 3 and 7, the fan case 19 is located behind the base plate 15 and is arranged between the base plate 15 and the first metal plate 21 in the front-rear direction.

風扇殼體19在其下部具備：風扇收納部41、及通訊裝置收納部42。風扇收納部41及通訊裝置收納部42分別將風扇17及通訊裝置40收納於風扇殼體19之前側。在風扇收納部41之下部配置有用以引入外部空氣的吸氣口49。The fan housing 19 includes a fan housing 41 and a communication device housing 42 at its lower part. The fan accommodating portion 41 and the communication device accommodating portion 42 respectively accommodate the fan 17 and the communication device 40 on the front side of the fan housing 19. A suction port 49 for taking in outside air is arranged at the lower part of the fan storage portion 41.

位於風扇17及通訊裝置40之後方的風扇殼體19的部分是隔開風扇17及通訊裝置40之後側的空間、及風扇殼體19與第1金屬板21之間的空間。亦即，風扇殼體19之一部分作為第2區隔件而發揮功能。在圖5~圖8中，加熱調理器1之前側及後側分別對應該等圖式中之遠側及近側。針對圖8將於後敘述。The part of the fan housing 19 located behind the fan 17 and the communication device 40 separates the space behind the fan 17 and the communication device 40 and the space between the fan housing 19 and the first metal plate 21. That is, a part of the fan case 19 functions as a second zone partition. In Figs. 5 to 8, the front side and the back side of the heating conditioner 1 correspond to the far side and the near side in these figures, respectively. Figure 8 will be described later.

在風扇殼體19之上半部中，形成有在上下方向上排列的二個貫通孔19a。二個貫通孔19a各自為例如在上下方向上延伸之細長的孔。在貫通孔19a之後側，配置有在前側與背面視角下之左側開口的蓋體19c。In the upper half of the fan case 19, two through holes 19a arranged in the vertical direction are formed. Each of the two through holes 19a is, for example, an elongated hole extending in the up-down direction. On the rear side of the through hole 19a, a lid body 19c that opens on the left side when viewed from the front side and the back side is arranged.

蓋體19c會改變通過貫通孔19a並從風扇殼體19之前側朝向後側流動的冷卻風之方向。其結果，已通過貫通孔19a的冷卻風會沿著風扇殼體19之後面而在背面視角下流向左方向。The cover 19c changes the direction of the cooling wind that passes through the through hole 19a and flows from the front side to the rear side of the fan housing 19. As a result, the cooling air that has passed through the through hole 19a flows along the rear surface of the fan case 19 to the left when viewed from the back.

在風扇殼體19之下半部中，形成有作為第1貫通孔而發揮功能的貫通孔43。貫通孔43是例如三角形的孔。在貫通孔43之上方形成有從風扇殼體19向後方突出的壁44。In the lower half of the fan case 19, a through hole 43 that functions as a first through hole is formed. The through hole 43 is, for example, a triangular hole. A wall 44 protruding rearward from the fan housing 19 is formed above the through hole 43.

壁44是配置於風扇殼體19之後面且在水平方向上延伸之細長的板。壁44會改變通過貫通孔43並從風扇殼體19之前側朝向後側流動的冷卻風之方向。其結果，已通過貫通孔43的冷卻風會沿著風扇殼體19之後面而流向下方向。The wall 44 is an elongated plate arranged on the rear surface of the fan housing 19 and extending in the horizontal direction. The wall 44 changes the direction of the cooling wind that passes through the through hole 43 and flows from the front side to the rear side of the fan housing 19. As a result, the cooling air that has passed through the through hole 43 flows downward along the rear surface of the fan case 19.

背面視角下，在風扇殼體19之下部之左側，形成有從風扇殼體19向後方突出的壁19d。壁19d是配置於風扇殼體19之後面且在鉛直方向上延伸之細長的板。壁19d會改變在背面視角下從蓋體19c朝向左側流動的冷卻風之方向。其結果，該冷卻風在背面視角下會流向右方向。When viewed from the back, on the left side of the lower part of the fan housing 19, a wall 19d protruding rearward from the fan housing 19 is formed. The wall 19d is an elongated plate arranged on the rear surface of the fan housing 19 and extending in the vertical direction. The wall 19d changes the direction of the cooling air flowing from the cover 19c to the left when viewed from the back. As a result, the cooling air flows to the right when viewed from the back.

在風扇殼體19之上部中，形成有作為第2貫通孔而發揮功能的貫通孔19b。在風扇殼體19之上端形成有排氣口45。沿著風扇殼體19之後面而流向上方的冷卻風會通過貫通孔19b而回到風扇殼體19之前側，並從排氣口45排氣。In the upper part of the fan case 19, the through-hole 19b which functions as a 2nd through-hole is formed. An exhaust port 45 is formed at the upper end of the fan case 19. The cooling air flowing upward along the rear surface of the fan case 19 returns to the front side of the fan case 19 through the through hole 19 b, and is exhausted from the exhaust port 45.

圖8是從圖7所示的狀態更進一步地將風扇殼體19拆卸後的狀態下的門7之一部分的後方立體圖。如圖3及圖8所示，基板15、顯示部9、風扇17、及通訊裝置40位於外框13之後方，並在前後方向上配置於外框13與風扇殼體19之間。FIG. 8 is a rear perspective view of a part of the door 7 in a state where the fan case 19 is further removed from the state shown in FIG. 7. As shown in FIGS. 3 and 8, the substrate 15, the display unit 9, the fan 17, and the communication device 40 are located behind the outer frame 13 and are arranged between the outer frame 13 and the fan housing 19 in the front-rear direction.

風扇17的吸入口17a是朝向已關閉的狀態下的門7之前後方向。風扇17的吐出口17b是朝向已關閉的狀態下的門7之上方向。因此，風扇17會在已關閉的狀態下的門7之前後方向上吸入空氣。The suction port 17a of the fan 17 faces the front and back direction of the door 7 in the closed state. The discharge port 17b of the fan 17 faces upwards of the door 7 in the closed state. Therefore, the fan 17 sucks air in the front and back directions of the door 7 in the closed state.

亦即，風扇17之吸入方向是與風扇殼體19的吸氣口49所朝向之方向交錯為例如直角。風扇17會在與風扇17吸入空氣之方向交錯為例如直角之方向上吐出空氣。因此，風扇17的扇葉的旋轉軸會朝向前後方向。作為風扇17可以使用例如多翼式風扇(sirocco fan)。That is, the suction direction of the fan 17 is staggered with the direction in which the suction port 49 of the fan housing 19 faces, for example, at a right angle. The fan 17 discharges the air in a direction that intersects the direction in which the fan 17 sucks in air, for example, at a right angle. Therefore, the rotation axis of the blade of the fan 17 faces the front-rear direction. As the fan 17, for example, a sirocco fan can be used.

圖9是風扇殼體19的前方立體圖。圖10是風扇17及通訊裝置40已收納於風扇殼體19的狀態下的風扇殼體19的前方立體圖。在圖9~圖11中，加熱調理器1之前側及後側分別對應該等圖式中之遠側及近側。針對圖11將於後敘述。FIG. 9 is a front perspective view of the fan housing 19. FIG. 10 is a front perspective view of the fan housing 19 in a state where the fan 17 and the communication device 40 have been housed in the fan housing 19. In FIGS. 9 to 11, the front side and the back side of the heating conditioner 1 correspond to the far side and the near side in the drawings, respectively. Figure 11 will be described later.

如圖9及圖10所示，風扇17是配置成與通訊裝置40鄰接。風扇殼體19具有位於風扇17與通訊裝置40之間且形成在風扇殼體19之後面的分隔壁46。分隔壁46是一體地形成於風扇殼體19。分隔壁46是作為將風扇17與通訊裝置40隔開的第1區隔件而發揮作用。As shown in FIGS. 9 and 10, the fan 17 is arranged to be adjacent to the communication device 40. The fan housing 19 has a partition wall 46 located between the fan 17 and the communication device 40 and formed on the back of the fan housing 19. The partition wall 46 is formed integrally with the fan housing 19. The partition wall 46 functions as a first zone partition that separates the fan 17 from the communication device 40.

從風扇17送出之空氣會從配置於風扇殼體19之下部的吸氣口49被引入。在加熱調理器1的底壁5e之下方之前部，配置有用以將已在加熱室5中被加熱之空氣排氣至外部的排氣口。因此，當在加熱室5中加熱被加熱物時，會有從吸氣口49引入之外部空氣的溫度超過通訊裝置40所容許之動作溫度範圍的可能性。The air sent from the fan 17 is drawn in from an air suction port 49 arranged at the lower part of the fan housing 19. At the front portion below the bottom wall 5e of the heating conditioner 1, an exhaust port is arranged to exhaust the air heated in the heating chamber 5 to the outside. Therefore, when the object to be heated is heated in the heating chamber 5, the temperature of the outside air introduced from the suction port 49 may exceed the operating temperature range allowed by the communication device 40.

分隔壁46會防止從風扇17送出之空氣被直接吹附於通訊裝置40。藉此，即便從風扇17送出之空氣的溫度超過通訊裝置40所容許之動作溫度範圍，仍可抑制通訊裝置40因從風扇17送出之高溫之空氣而被加熱的情形。The partition wall 46 prevents the air sent from the fan 17 from being directly attached to the communication device 40. Thereby, even if the temperature of the air sent from the fan 17 exceeds the operating temperature range allowed by the communication device 40, the communication device 40 can be prevented from being heated by the high-temperature air sent from the fan 17.

分隔壁46可以區隔風扇收納部41與通訊裝置收納部42之間的空間整體，亦可區隔該空間之一部分。例如，分隔壁46亦可具有用以使配線通過的孔，前述配線是將風扇17或通訊裝置40連接至基板15或電源電路(未圖示)。The partition wall 46 can separate the entire space between the fan receiving portion 41 and the communication device receiving portion 42 or a part of the space. For example, the partition wall 46 may also have holes for the passage of wires, and the aforementioned wires are used to connect the fan 17 or the communication device 40 to the substrate 15 or the power supply circuit (not shown).

正面視角下，在風扇殼體19之左端配置有向前方突出的壁19e。正面視角下，在風扇殼體19的風扇收納部41之上方之左側，向前方突出的壁19g是平行於壁19e而配置。藉由壁19e與壁19g而形成溝19m。在溝19m之上部配置有貫通孔19a。在壁19g配置有孔19h。In a front view, a wall 19e protruding forward is arranged at the left end of the fan housing 19. In a front view, on the left side above the fan receiving portion 41 of the fan housing 19, a wall 19g protruding forward is arranged parallel to the wall 19e. A groove 19m is formed by the wall 19e and the wall 19g. A through hole 19a is arranged above the groove 19m. A hole 19h is arranged in the wall 19g.

在風扇收納部41之上部的開口與溝19m之間，藉由壁19e與壁47而形成有連接風路48。在連接風路48上配置有貫通孔43。Between the opening on the upper portion of the fan housing 41 and the groove 19m, a connecting air passage 48 is formed by the wall 19e and the wall 47. A through hole 43 is arranged in the connecting air duct 48.

圖11是用以說明形成於風扇殼體19之前面的風路的圖。如圖11所示，已從吸氣口49引入之空氣會從風扇17被送出至連接風路48。在連接風路48中，已被送出至連接風路48之空氣之一部分會通過貫通孔43而流向風扇殼體19之後側。剩餘之空氣會在壁19e與壁19g之間的溝19m中流向上方。FIG. 11 is a diagram for explaining the air passage formed on the front surface of the fan case 19. As shown in FIG. 11, the air introduced from the suction port 49 is sent out from the fan 17 to the connecting air passage 48. In the connecting air passage 48, a part of the air that has been sent to the connecting air passage 48 passes through the through hole 43 and flows to the rear side of the fan housing 19. The remaining air flows upward in the groove 19m between the wall 19e and the wall 19g.

在溝19m中流動之空氣之一部分會從孔19h朝向基板15流動。亦即，從風扇17至基板15的第1風路29包含：連接風路48、溝19m之下部、及孔19h。通過第1風路29，從風扇17送出之外部空氣可以將基板15冷卻。藉此，可以提升基板15之動作的信賴性。A part of the air flowing in the groove 19m flows toward the substrate 15 from the hole 19h. That is, the first air path 29 from the fan 17 to the base plate 15 includes the connecting air path 48, the lower part of the groove 19m, and the hole 19h. The outside air sent from the fan 17 can cool the substrate 15 through the first air passage 29. Thereby, the reliability of the operation of the substrate 15 can be improved.

第1風路29是作為單一方向的風路而形成。因此，可以降低第1風路29中之壓力損失。已被加熱之空氣會朝向配置於風扇殼體19之上端的排氣口45而在第1風路29內流動。藉此，可以更加降低壓力損失。其結果，可確保在第1風路29中流動之冷卻風的風量，並提升基板15的冷卻效率。The first air passage 29 is formed as a unidirectional air passage. Therefore, the pressure loss in the first air passage 29 can be reduced. The heated air flows in the first air passage 29 toward the exhaust port 45 arranged at the upper end of the fan case 19. In this way, the pressure loss can be further reduced. As a result, the air volume of the cooling air flowing through the first air passage 29 can be ensured, and the cooling efficiency of the substrate 15 can be improved.

孔19h是配置於比通訊裝置收納部42更上方。因此，當從孔19h朝向基板15流入之空氣比存在於風扇殼體19之前方的空間之空氣更高溫時，便不會流動至通訊裝置收納部42那一邊，而會上升至基板15那一邊。藉此，可以抑制通訊裝置40因高溫之空氣而被加熱的情形。The hole 19h is arranged above the communication device storage portion 42. Therefore, when the air flowing from the hole 19h toward the substrate 15 is hotter than the air existing in the space in front of the fan housing 19, it will not flow to the side of the communication device receiving portion 42 but will rise to the side of the substrate 15 . Thereby, it is possible to prevent the communication device 40 from being heated by the high-temperature air.

在孔19h中，未流向基板15那一邊之空氣會在溝19m中更流向上方，然後從貫通孔19a流向風扇殼體19之後側。In the hole 19h, the air that does not flow to the side of the substrate 15 flows upward in the groove 19m, and then flows to the rear side of the fan housing 19 from the through hole 19a.

由於省空間化，溝19m具有比風扇17的開口之寬度更狹窄之寬度。因此，在溝19m與風扇17之間配置有連接風路48，前述連接風路48具有從風扇17的開口朝向溝19m圓滑縮窄的形狀。正面視角下，從風扇收納部41之左側的壁之上端朝向右方向形成有曲面狀的壁19e。正面視角下，從風扇收納部41之右側的分隔壁46之上端朝向左方向形成有平面狀的壁47。Due to the space saving, the groove 19m has a narrower width than the width of the opening of the fan 17. Therefore, a connecting air passage 48 is arranged between the groove 19m and the fan 17, and the connecting air passage 48 has a shape that smoothly narrows from the opening of the fan 17 toward the groove 19m. When viewed from the front, a curved wall 19e is formed from the upper end of the left side wall of the fan housing 41 toward the right direction. In a front view, a flat wall 47 is formed from the upper end of the partition wall 46 on the right side of the fan housing 41 toward the left direction.

藉由壁19e與壁47而形成有連接風路48。傾斜配置壁47，以使壁47與分隔壁46所構成的角度成為比直角更大。藉此，可以抑制空氣滯留在風扇17與溝19m之間的空間。其結果，可以抑制風扇17周圍之空氣成為高溫，並抑制鄰接的通訊裝置40成為高溫。A connecting air passage 48 is formed by the wall 19e and the wall 47. The wall 47 is arranged obliquely so that the angle formed by the wall 47 and the partition wall 46 becomes larger than the right angle. This can prevent air from staying in the space between the fan 17 and the groove 19m. As a result, it is possible to prevent the air around the fan 17 from becoming high temperature, and to prevent the adjacent communication device 40 from becoming high temperature.

貫通孔43是在連接風路48中沿著壁47而配置。壁47是如前述地傾斜配置。因此，貫通孔43具有三角形的形狀，前述三角形具有沿著壁47傾斜的邊。藉此，可以在連接風路48配置貫通孔43而有效地利用空間。然而，貫通孔43亦可具有任意的形狀。The through hole 43 is arranged along the wall 47 in the connecting air passage 48. The wall 47 is arranged obliquely as described above. Therefore, the through hole 43 has a triangular shape, and the aforementioned triangle has sides inclined along the wall 47. Thereby, the through-hole 43 can be arrange|positioned in the connection air path 48, and space can be utilized effectively. However, the through hole 43 may have any shape.

圖12是用以說明形成於風扇殼體19之後面的風路的圖。如圖12所示，已通過貫通孔43之空氣會藉由壁44而朝向通訊裝置收納部42流動。亦即，從風扇17至通訊裝置40與第1金屬板21之間的空間的第2風路31包含：連接風路48、貫通孔43、及壁44。FIG. 12 is a diagram for explaining the air passage formed on the rear surface of the fan case 19. As shown in FIG. 12, the air that has passed through the through hole 43 flows toward the communication device storage portion 42 through the wall 44. That is, the second air path 31 from the fan 17 to the space between the communication device 40 and the first metal plate 21 includes the connecting air path 48, the through hole 43, and the wall 44.

藉此，可以透過風扇殼體19間接地藉由從風扇17送出之外部空氣來冷卻通訊裝置40。其結果，可以提升通訊裝置40之動作的信賴性。Thereby, the communication device 40 can be cooled by the external air sent from the fan 17 indirectly through the fan housing 19. As a result, the reliability of the operation of the communication device 40 can be improved.

藉由將貫通孔43配置於與風扇17緊鄰之上方的連接風路48，冷卻風會變得容易流向配置於更下部的通訊裝置收納部42。藉此，可以提升通訊裝置40的冷卻效率。By arranging the through hole 43 in the connecting air passage 48 immediately above the fan 17, the cooling air can easily flow to the communication device storage part 42 arranged further below. In this way, the cooling efficiency of the communication device 40 can be improved.

已通過貫通孔43之空氣會從壁44與壁19d之間流向上方。已通過貫通孔19a之空氣會在第3風路33中流動，前述第3風路33是通過基板15與第1金屬板21之間的空間的風路。藉此，可以透過風扇殼體19間接地藉由從風扇17送出之外部空氣來冷卻基板15。其結果，可以提升基板15之動作的信賴性。The air that has passed through the through hole 43 flows upward from between the wall 44 and the wall 19d. The air that has passed through the through hole 19 a flows through the third air passage 33, which is an air passage that passes through the space between the substrate 15 and the first metal plate 21. Thereby, the substrate 15 can be cooled by the external air sent from the fan 17 indirectly through the fan housing 19. As a result, the reliability of the operation of the substrate 15 can be improved.

沿著風扇殼體19之後面而流向上方之空氣會通過貫通孔19b而回到風扇殼體19之前側，並從排氣口45排氣。The air flowing upward along the rear surface of the fan case 19 returns to the front side of the fan case 19 through the through hole 19 b, and is exhausted from the exhaust port 45.

已通過到達風扇殼體19之後面的風路的冷卻風會在風扇殼體19之後面與第1金屬板21之間的空間中流動。藉此，可以冷卻第1金屬板21。同時，該冷卻風會在風扇殼體19與第1金屬板21之間形成空氣幕(Air curtain)。藉此，可以減低對風扇殼體19的傳熱。The cooling air that has passed through the air path reaching the rear of the fan case 19 flows in the space between the rear of the fan case 19 and the first metal plate 21. Thereby, the first metal plate 21 can be cooled. At the same time, the cooling air forms an air curtain between the fan housing 19 and the first metal plate 21. Thereby, the heat transfer to the fan housing 19 can be reduced.

即便在第1金屬板21與風扇殼體19之間的空間中所存在之空氣因第1金屬板21之熱而被加熱的情況下，仍可通過第2風路31及第3風路33來將該空氣迅速地從排氣口45排氣。其結果，可以抑制熱積存於第1金屬板21與風扇殼體19之間的空間，並提升基板15及通訊裝置40的冷卻效率。Even if the air existing in the space between the first metal plate 21 and the fan housing 19 is heated by the heat of the first metal plate 21, it can still pass through the second air passage 31 and the third air passage 33 To quickly exhaust the air from the exhaust port 45. As a result, it is possible to prevent heat from accumulating in the space between the first metal plate 21 and the fan case 19, and to improve the cooling efficiency of the substrate 15 and the communication device 40.

圖13A~圖13C是用以針對外框13的吸氣口14進行說明的圖。圖13A是外框13、風扇殼體19、及電波洩漏防止板25的後面圖。圖13B是沿著圖13A之13B-13B線的截面圖。圖13C是沿著圖13A之13B-13B線的截面的立體圖。13A to 13C are diagrams for explaining the air inlet 14 of the outer frame 13. FIG. 13A is a rear view of the outer frame 13, the fan case 19, and the electric wave leakage prevention plate 25. FIG. Fig. 13B is a cross-sectional view taken along line 13B-13B of Fig. 13A. Fig. 13C is a perspective view of a cross section taken along line 13B-13B of Fig. 13A.

如圖13A~圖13B所示，正如前述，在風扇殼體19之下端配置有吸氣口49。吸氣口14是配置於外框13之下表面的吸氣口49的附近。在吸氣口14之周邊，會有已從加熱室5被排氣的高溫之空氣存在的情況。尤其是，從離加熱室5更近的吸氣口14之正下方起之後側之空氣，會有溫度比吸氣口14之前側之空氣更高的可能性。As shown in FIGS. 13A to 13B, as mentioned above, an air suction port 49 is arranged at the lower end of the fan housing 19. The suction port 14 is arranged in the vicinity of the suction port 49 on the lower surface of the outer frame 13. In the vicinity of the suction port 14, high-temperature air that has been exhausted from the heating chamber 5 may exist. In particular, the air on the back side from just below the suction port 14 which is closer to the heating chamber 5 may have a higher temperature than the air on the front side of the suction port 14.

本實施形態中，在吸氣口14之周圍配置有用以將外部空氣引導至吸氣口14的引導件(Guide)50。引導件50是形成為面向前側而非正下方。藉此，可以將存在於吸氣口14之前側而非正下方的更接近室溫之空氣從吸氣口14吸入。In this embodiment, a guide 50 for guiding the outside air to the suction port 14 is arranged around the suction port 14. The guide 50 is formed to face the front side instead of directly below. Thereby, the air closer to the room temperature existing in front of the suction port 14 but not directly below it can be sucked in from the suction port 14.

其結果，可以提升冷卻風所帶來的冷卻效率。藉由作成為不將高溫之空氣送風，而可以抑制將通訊裝置40、基板15等電氣零件加熱的情形。As a result, the cooling efficiency by the cooling air can be improved. By not blowing high-temperature air, it is possible to suppress heating of electrical components such as the communication device 40 and the substrate 15.

圖14是外框13與風扇殼體19的後面立體圖。如圖14所示，正如前述，在風扇殼體19之上端配置有排氣口45。已通過風扇殼體19之前面側的第1風路29之空氣會直接從排氣口45排氣。FIG. 14 is a rear perspective view of the outer frame 13 and the fan housing 19. As shown in FIG. 14, as described above, an exhaust port 45 is arranged at the upper end of the fan housing 19. The air that has passed through the first air passage 29 on the front side of the fan case 19 is directly exhausted from the exhaust port 45.

已通過風扇殼體19之後面側的第2風路31及第3風路33之空氣會從貫通孔19b回到風扇殼體19之前面。該空氣會與已通過第1風路29之空氣一起從排氣口45排氣。排氣口45之上方被框51覆蓋。因此，即便水分侵入外框13內，仍可保護基板15及通訊裝置40不受潮。The air that has passed through the second air passage 31 and the third air passage 33 on the rear side of the fan case 19 returns to the front surface of the fan case 19 from the through hole 19 b. This air is exhausted from the exhaust port 45 together with the air that has passed through the first air passage 29. The upper part of the exhaust port 45 is covered by a frame 51. Therefore, even if moisture penetrates into the outer frame 13, the substrate 15 and the communication device 40 can still be protected from moisture.

圖15是風扇殼體19的風扇收納部41之周邊的放大圖。如圖15所示，風扇17具備：固定部54a、及固定部54b。固定部54a、54b具有孔，前述孔是在將風扇17安裝於風扇收納部41時，為了定位而以插銷將風扇17固定用的孔。藉由在該孔中***已形成於外框13或風扇殼體19的插銷，風扇17便可安裝於風扇收納部41。FIG. 15 is an enlarged view of the periphery of the fan housing portion 41 of the fan case 19. As shown in Fig. 15, the fan 17 includes a fixing portion 54a and a fixing portion 54b. The fixing portions 54a and 54b have holes, and the aforementioned holes are holes for fixing the fan 17 with a plug for positioning when the fan 17 is installed in the fan housing portion 41. By inserting the plug formed in the outer frame 13 or the fan housing 19 into the hole, the fan 17 can be installed in the fan receiving portion 41.

若僅以插銷固定，在風扇17作動時會有因振動而產生聲響的情況。本實施形態中，押壓部53a與押壓部53b是配置於風扇殼體19。押壓部53a與押壓部53b是在風扇殼體19的風扇收納部41的附近將風扇17壓接於外框13。If it is only fixed with a plug, when the fan 17 is operated, a sound may be generated due to vibration. In this embodiment, the pressing portion 53 a and the pressing portion 53 b are arranged in the fan case 19. The pressing portion 53 a and the pressing portion 53 b press the fan 17 to the outer frame 13 in the vicinity of the fan housing portion 41 of the fan case 19.

在風扇殼體19與外框13兩邊配置有螺孔52a與螺孔52b。螺孔52a、52b是作為鎖緊部而發揮功能，前述鎖緊部是用以在押壓部53a、53b的附近將風扇殼體19與外框13鎖緊。A screw hole 52a and a screw hole 52b are arranged on both sides of the fan housing 19 and the outer frame 13. The screw holes 52a and 52b function as locking portions, and the locking portions are used to lock the fan housing 19 and the outer frame 13 in the vicinity of the pressing portions 53a and 53b.

將風扇17固定於風扇收納部41後，將螺絲***螺孔52a、52b並鎖緊。藉此，可以藉由押壓部53a、53b將風扇17以適當之強度壓接於外框13。其結果，可以抑制風扇17動作時，風扇17及風扇收納部41振動而產生振動音的情形。After the fan 17 is fixed to the fan receiving portion 41, screws are inserted into the screw holes 52a, 52b and tightened. Thereby, the fan 17 can be crimped to the outer frame 13 with appropriate strength by the pressing portions 53a and 53b. As a result, it can be suppressed that the fan 17 and the fan housing portion 41 vibrate and generate vibration noise when the fan 17 is operating.

押壓部53a、53b、或螺孔52a、52b是配置於固定部54a、54b的附近。固定部54a、54b是安裝風扇17時用以固定風扇17的構件。The pressing portions 53a, 53b, or the screw holes 52a, 52b are arranged in the vicinity of the fixing portions 54a, 54b. The fixing portions 54a and 54b are members for fixing the fan 17 when the fan 17 is installed.

固定部54a、54b具有假定了在其附近施加某種程度的壓力的強度。因此，只要在固定部54a、54b的附近將風扇17壓接於外框13，便可不對風扇17的動作造成影響並抑制風扇17的振動。The fixing portions 54a and 54b have strengths that assume a certain degree of pressure is applied to the vicinity thereof. Therefore, as long as the fan 17 is press-contacted to the outer frame 13 in the vicinity of the fixing portions 54a and 54b, the operation of the fan 17 is not affected and the vibration of the fan 17 can be suppressed.

螺孔52a、52b與配置於風扇殼體19之其他位置的其他螺孔52c具有相同的直徑。藉此，可以減少在組裝風扇殼體19時所使用之螺絲的種類，而可以減低製造成本。The screw holes 52 a and 52 b have the same diameter as other screw holes 52 c arranged in other positions of the fan housing 19. Thereby, the types of screws used when assembling the fan housing 19 can be reduced, and the manufacturing cost can be reduced.

根據本實施形態，是將風扇17之一部分配置於電波洩漏防止板25之內側。藉此，可以縮短門7之高度，而可以實現加熱調理器1的小型化。藉由將基板15及通訊裝置40配置於門7內，可以在加熱室5內確保寬廣的空間，並使加熱調理器1小型化。According to this embodiment, a part of the fan 17 is arranged inside the radio wave leakage prevention plate 25. Thereby, the height of the door 7 can be shortened, and the miniaturization of the heating conditioner 1 can be realized. By arranging the substrate 15 and the communication device 40 in the door 7, a wide space can be secured in the heating chamber 5, and the heating conditioner 1 can be miniaturized.

本實施形態中，是針對使用微波、加熱器、蒸氣來將被加熱物加熱之加熱調理器進行了說明。然而，本揭示之技術可適用於任意方式之加熱調理器。In this embodiment, the heating conditioner that uses microwaves, heaters, and steam to heat the object to be heated has been described. However, the technology of the present disclosure can be applied to any heating conditioner.
