It includes a back side circulation duct (rear side circulation duct) 62 so that the air flow sent out by the blower 10 blows out from the back side circulation duct 62 to the storage chamber 3 and is sucked into the upper circulation duct 61 and sent out again from the fan 10 It has become. As described above, the circulation duct 60 enables the air sent out by the blower 10 to circulate in the inside of the housing 2 including the storage chamber 3.

送風部10は、上側仕切板4と天井壁7との間に配置されたファン部11と、筐体2の天井部2aと天井壁7との間に配置されファン部11を駆動するファン駆動部12とを備え、ファン部11は、シロッコファン等からなる送風装置13と、送風装置13の下側から空気を吸入する吸気側に設けられる吸気部14と空気を排出する吐出側に設けられる吐出部15とケーシング16とを有している。また、送風装置13はケーシング16に収納されている。そして、送風部10のファン駆動部12の駆動により送風装置13が回転駆動し、送風部10の送風装置13によって送り出され筐体2内に流れる空気流Vが形成される。   The fan unit 10 is a fan drive disposed between the upper partition plate 4 and the ceiling wall 7 and between the ceiling 2 a of the housing 2 and the ceiling wall 7 to drive the fan unit 11. The fan unit 11 includes an air blower 13 including a sirocco fan or the like, an air intake portion 14 provided on an intake side for sucking in air from the lower side of the air blower 13, and a discharge side for discharging air. It has a discharge part 15 and a casing 16. The blower 13 is housed in a casing 16. Then, the air blower 13 is rotationally driven by the drive of the fan drive unit 12 of the air blower 10, and the air flow V which is sent out by the air blower 13 of the air blower 10 and flows into the housing 2 is formed.

加熱部20は、収納室3の後側に配置された筐体2の背面壁2bと背面仕切板5との間に配置され、内部に筐体2の上下方向に延びるように画定された正面視略U字状の加熱ヒータ21(図2参照)を備え、送風装置13の吐出側の吐出部15と空気流Vの経路として接続されている。そして、筐体2の背面壁2bと背面仕切板5との間に、空気流Vの経路である背面循環ダクト62が形成されている。   The heating unit 20 is disposed between the back wall 2 b of the housing 2 disposed on the rear side of the storage chamber 3 and the back partition plate 5, and is a front surface defined so as to extend vertically in the housing 2. A heater 21 (see FIG. 2) having a substantially U-shaped view is provided, and is connected as a path of the air flow V to the discharge portion 15 on the discharge side of the air blower 13. A rear circulation duct 62, which is a path of the air flow V, is formed between the rear wall 2b of the housing 2 and the rear partition plate 5.

背面仕切板5には、図2に示す通り空気流Vを収納室3に導入する複数の吹出し孔51が各棚9に向かって開口され、吹出し孔51は、上側にある棚9に対応する配列数や開口面積と下側にある棚9に対応する配列数や開口面積が異なっている。本実施形態では、下側に棚9に対応する吹出し孔51の総開口面積は、上側の棚9に対応する吹出し孔51の総開口面積より小さく設定されている。   As shown in FIG. 2, a plurality of blowout holes 51 for introducing the air flow V into the storage chamber 3 are opened toward the shelves 9 in the back surface partition plate 5, and the blowout holes 51 correspond to the shelves 9 located on the upper side. The arrangement number and the opening area are different from the arrangement number and the opening area corresponding to the lower shelf 9. In the present embodiment, the total opening area of the blowout holes 51 corresponding to the shelves 9 on the lower side is set smaller than the total opening area of the blowout holes 51 corresponding to the upper shelves 9.

また、背面循環ダクト62から最下段の棚9の下側にある収納室3の底部3aには、断面凹形状の誘導凹部3bが前後方向に沿って形成されている。さらに背面仕切板5の下端には、前記誘導凹部3bに空気流Vを誘導する風量調整部52が形成されている。風量調整部52は、背面仕切板5の延在する方向と略直角方向に延び筐体2の背面壁2bに向かって突出する抑制板52aと、抑制板52aの先端と背面壁2bとの間に形成される開口52bとを有している。そして、風量調整部52の開口52bと略同じ幅Dで誘導凹部3bが形成されている(図4参照)。   Further, in the bottom portion 3a of the storage chamber 3 located under the lowermost shelf 9 from the rear surface circulation duct 62, a guiding concave portion 3b having a concave cross section is formed along the front-rear direction. Further, at the lower end of the back surface partition plate 5, an air flow rate adjusting portion 52 for guiding the air flow V to the guide recess 3b is formed. The air flow rate adjusting portion 52 extends in a direction substantially perpendicular to the direction in which the back surface partition plate 5 extends, and between the suppression plate 52a projecting toward the back surface wall 2b of the housing 2 and the tip of the suppression plate 52a and the back surface wall 2b And an opening 52b formed in the And the induction | guidance | derivation recessed part 3b is formed in the width | variety D substantially the same as the opening 52b of the air volume adjustment part 52 (refer FIG. 4).

風量調整部52の開口52bと略同じ幅Dの誘導凹部3bが形成されることにより、風量調整部52から収納室3の前部まで幅Dの変化がなく、内部を流れる空気はスムーズに流動するため、開口52bから吹き出された空気流Vは、乱れることなく前部まで誘導される。そして、抑制板52aを設けることにより、背面循環ダクト62の下方から集中して空気流Vが吹き出されるのを抑制し、吹出し孔51から収納室3内への吹き出しが促される。   There is no change in the width D from the air volume adjustment unit 52 to the front of the storage chamber 3 by forming the induction recess 3b having substantially the same width D as the opening 52b of the air volume adjustment unit 52, and the air flowing inside flows smoothly. Therefore, the air flow V blown out from the opening 52b is guided to the front without being disturbed. And by providing the control board 52a, it is suppressed that the air flow V blows out intensively from the downward direction of the back surface circulation duct 62, and the blowout from the blowout hole 51 into the storage chamber 3 is urged.

筐体2の背面壁2bと背面仕切板5との間には、複数の加熱ヒータ21を配置することにより、一つの加熱ヒータ21に水供給部25を備える蒸気発生部26を有していても良い。蒸気発生部26は、加熱ヒータ21に取り付けられ、水供給部25から供給された水が加熱して収納室3に供給する蒸気を生成する。   By arranging a plurality of heaters 21 between the rear wall 2 b of the housing 2 and the rear partition plate 5, the single heater 21 is provided with a steam generation unit 26 provided with a water supply unit 25. Also good. The steam generating unit 26 is attached to the heater 21 and generates heat to be supplied to the storage chamber 3 by heating the water supplied from the water supply unit 25.

筐体2の背面壁2bと並列している背面仕切板5と略平行に配置される加熱ヒータ21は、背面循環ダクト62の上下方向に沿って配置されるため、空気流Vの送風方向に沿って位置づけられることになり、空気流Vの流れを妨げることが無くなる。また、加熱時は加熱ヒータ21との接触時間が長くなるため効率よく空気を加熱することができる。そして、背面仕切板5を介して加熱部20と収納室3とが隣接しているため、加熱された空気が直接収納室3に供給されるため加熱温度の低下や送風損失を招くことなく収納室3内の加熱対象物Kをムラなく効率よく加熱することができる。   The heater 21 disposed substantially in parallel with the back surface partition plate 5 in parallel with the back surface wall 2 b of the housing 2 is disposed along the vertical direction of the back surface circulation duct 62, It will be positioned along, and will not disturb the flow of the air flow V. Moreover, since the contact time with the heater 21 becomes long at the time of heating, air can be efficiently heated. And, since the heating unit 20 and the storage chamber 3 are adjacent to each other through the back surface partition plate 5, the heated air is directly supplied to the storage chamber 3, and the storage is performed without causing the decrease of the heating temperature or the air loss. The heating target K in the chamber 3 can be efficiently heated without unevenness.

冷却ユニット30は、上側仕切板4と天井壁7との間に配置される冷却器31と、天井部2aと天井壁7との間に配置される冷却ユニット本体32とを備え、冷却ユニット本体32は、天井壁7の上面にボルト等で固定されるユニット台33と、ユニット台33に固定される凝縮器34と冷却駆動部35とを有している。また、ユニット台33の下部には冷却器固定台36が設けられ、冷却器31が冷却器固定台36に固定されている。冷却器固定台36は、天井壁7に形成された冷却開口部37に挿入載置される。そして、冷却ユニット本体32により冷却される冷却器31内を空気流Vが通過することにより冷却され送風装置13に送り込まれる。尚、空気流Vは、冷却器31で冷却される場合と冷却ユニット本体32が停止して冷却されない場合とがある。   The cooling unit 30 includes a cooler 31 disposed between the upper partition plate 4 and the ceiling wall 7 and a cooling unit body 32 disposed between the ceiling portion 2 a and the ceiling wall 7. The reference numeral 32 has a unit base 33 fixed to the upper surface of the ceiling wall 7 with a bolt or the like, a condenser 34 fixed to the unit base 33, and a cooling drive unit 35. A cooler fixing stand 36 is provided below the unit stand 33, and the cooler 31 is fixed to the cooler fixing stand 36. The cooler fixing base 36 is inserted and placed in a cooling opening 37 formed in the ceiling wall 7. Then, the air flow V passes through the inside of the cooler 31 cooled by the cooling unit main body 32, and is cooled and sent to the blower 13. The air flow V may be cooled by the cooler 31 or may not be cooled because the cooling unit body 32 is stopped.

また、加熱調理装置1は、開閉扉6の上側の筐体2に収納室3内の温度や湿度を設定し時間調整を可能とする制御盤Sが設けられている。   Moreover, the control panel S which sets temperature and humidity in the storage chamber 3 and enables time adjustment is provided in the housing | casing 2 of the upper side of the opening-closing door 6 of the heating-cooking apparatus 1. FIG.

図5は、上側仕切板4の正面斜視図である。図5を用いて上側仕切板4を詳述する。   FIG. 5 is a front perspective view of the upper side partition plate 4. The upper partition plate 4 will be described in detail with reference to FIG.

上側仕切板4は、略平板状の金属板等からなり、天井壁7に固定される送風装置13と冷却器31とを収納室3から仕切る役目をなし、送風装置13の駆動により送出される空気流Vを冷却器31から送風装置13の下方に開口した吸気部14に誘導する。さらに送風部10や冷却ユニット30からの落下物等を受け止め、収納室3への落下を防止している。   The upper partition plate 4 is made of a substantially flat metal plate or the like, and serves to divide the blower 13 fixed to the ceiling wall 7 and the cooler 31 from the storage chamber 3 and is delivered by the drive of the blower 13. The air flow V is guided from the cooler 31 to the air intake portion 14 opened below the air blower 13. Furthermore, it receives falling objects and the like from the air blowing unit 10 and the cooling unit 30, and prevents the object from falling into the storage chamber 3.

そして、上側仕切板4は、その一端が開閉扉6と離間して収納室3の上側に配置されることにより、収納室3からの空気を吸入し、上側循環ダクト61に連通する吸気口41を収納室3の上側(上部)でかつ前側(前部)の領域に形成する。本実施形態では、上側仕切板4の一端に上方向に突出する吸気口仕切部42の前方側に吸気口41が配置され、吸気口仕切部42に冷却器31に空気が流入する冷却器開口部43が形成されている。   The upper partition plate 4 is disposed on the upper side of the storage chamber 3 with one end thereof being separated from the open / close door 6 so that the air from the storage chamber 3 is sucked and the intake port 41 communicated with the upper circulation duct 61 Is formed on the upper side (upper side) and the front side (front side) of the storage chamber 3. In the present embodiment, the inlet 41 is disposed on the front side of the inlet partition 42 projecting upward at one end of the upper partition 4, and a cooler opening through which air flows into the cooler 31 in the inlet partition 42. The part 43 is formed.

また、上側仕切板4は、冷却器31の下方に位置する棚部44と、棚部44から収納室3方向に折り曲げられ送風装置13の下面に離間して配置され空気流Vを吸気部14に誘導する平板状の吸気導入ダクト45とを有している。吸気導入ダクト45は、上側仕切板4と送風装置13との間に画定され、冷却器31を通過した空気流Vは送風装置13に送る役目をする。   Further, the upper partition plate 4 is bent in the direction of the storage chamber 3 from the shelf 44 located below the cooler 31 and is separated from the lower surface of the air blower 13 from the shelf 44 and the air flow V is And a flat air inlet duct 45 for guiding the The air inlet duct 45 is defined between the upper partition 4 and the blower 13, and the air flow V having passed through the cooler 31 serves to feed the blower 13.

さらに、上側仕切板4は、四方を取り囲むように上側に突出する折り上げ部46を有し、上側仕切板4に落下する落下物を受け止め、例えば空気流V中に含まれる水蒸気の凝縮作用等により冷却器から落下する水滴を上側仕切板4の他端に設けられた排水部47に誘導する。上側仕切板4は、吸気口仕切部42に設けられた複数の係合部42aを冷却器31に係合し、排水部47を例えばケーシング16に形成された後述する排水開口17d等に取り付けることにより収納室3の上側に固定される。   Furthermore, the upper partition plate 4 has a fold-up portion 46 projecting upward so as to surround the four sides, and receives falling objects falling on the upper partition plate 4, for example, condensation of water vapor contained in the air flow V As a result, water droplets falling from the cooler are guided to the drainage portion 47 provided at the other end of the upper partition plate 4. The upper partition plate 4 engages a plurality of engaging portions 42a provided in the intake port partitioning portion 42 with the cooler 31, and attaches the drainage portion 47 to, for example, a drainage opening 17d described later formed in the casing 16 or the like. It fixes to the upper side of the storage chamber 3 by this.

図6は、送風部10に取り付けられるケーシング16を示し、(a)は正面斜視図、(b)は上面図である。図6を用いて、ケーシング16を詳述する。   6A and 6B show the casing 16 attached to the air blowing unit 10. FIG. 6A is a front perspective view, and FIG. 6B is a top view. The casing 16 will be described in detail with reference to FIG.

本実施形態においてケーシング16は、溶接等で一体化された略平板状の基台17と略円筒形状の枠体18とを有している。基台17は上側に立設する立壁17aと、立壁17aに対して略直角状に折り曲げられた平板17bと平板17bの先端から下方に向かって延在する係止板17cとを有している。立壁17aは冷却器31を通過してきた空気流Vを遮蔽し、強制的に吸気導入ダクト45に送り込む役目をする。また、平板17bの中央部分には開口した吸気部14が形成されている。   In the present embodiment, the casing 16 has a substantially flat base 17 and a substantially cylindrical frame 18 integrated by welding or the like. The base 17 has a standing wall 17a standing on the upper side, a flat plate 17b bent substantially at right angles to the standing wall 17a, and a locking plate 17c extending downward from the tip of the flat plate 17b. . The upright wall 17 a shields the air flow V passing through the cooler 31 and serves to forcibly feed the air into the intake air introduction duct 45. Further, an open intake portion 14 is formed at the central portion of the flat plate 17b.

枠体18は、送風装置13を収納し、吸気部14を取り囲むように略円形状の筒部18aと吐出部15を有し、吐出部15は、断面略コ字状で一対の支持部18bと下方に向かって傾斜した傾斜部18dを有している。なお、傾斜部18dには加熱ヒータ21を避ける切欠き部18cが形成されている。   The frame 18 accommodates the blower 13 and has a substantially circular cylindrical portion 18a and a discharge portion 15 so as to surround the intake portion 14. The discharge portion 15 has a substantially U-shaped cross section and a pair of support portions 18b. And an inclined portion 18d inclined downward. In addition, the notch part 18c which avoids the heater 21 is formed in the inclination part 18d.

上述の構成により、図6(b)に示す通り、送風装置13の回転により吸気部14から空気が送風装置13に強制的に吸引され、送風装置13の側面から筒部18aの内壁に向かって空気が放出され、筒部18aのなだらかな曲面により吐出部15から加熱部20に向かって効率よく流れる空気流Vを形成する。   According to the above-described configuration, as shown in FIG. 6B, air is forcibly sucked from the intake section 14 to the blower 13 by the rotation of the blower 13, and from the side surface of the blower 13 toward the inner wall of the cylindrical portion 18a. Air is released, and a gentle curved surface of the cylindrical portion 18a forms an air flow V which efficiently flows from the discharge portion 15 toward the heating portion 20.

図7は、上側仕切板4とケーシング16とを組み付けた状態を示す斜視図である。図7を用いて、上側仕切板4とケーシング16とを組み付けた状態を説明する。   FIG. 7 is a perspective view showing the upper partition plate 4 and the casing 16 assembled. The state where the upper side partition plate 4 and the casing 16 are assembled will be described using FIG. 7.

本実施形態では、上側仕切板4の排水部47の先端をケーシング16の係止板17cに形成された排水開口17dに挿入係合させ、上側仕切板4とケーシング16とが接合される。吸気導入ダクト45は、上側仕切板4とケーシング16の平板17b及び係止板17cとで形成され、ケーシング16の下部に吸気導入ダクト45と連通する吸気部14が形成される。上側仕切板4の冷却器開口部43とケーシング16の立壁17aで画定される部分には冷却器31が配置され、ケーシングの筒部18aには送風装置13が配置される。   In the present embodiment, the tip end of the drainage portion 47 of the upper partition plate 4 is inserted into and engaged with the drainage opening 17 d formed in the locking plate 17 c of the casing 16, and the upper partition plate 4 and the casing 16 are joined. The intake air introduction duct 45 is formed by the upper side partition plate 4 and the flat plate 17 b of the casing 16 and the locking plate 17 c, and the intake portion 14 communicating with the intake air introduction duct 45 is formed at the lower part of the casing 16. The cooler 31 is disposed in a portion defined by the cooler opening 43 of the upper partition plate 4 and the upright wall 17 a of the casing 16, and the blower 13 is disposed in the cylindrical portion 18 a of the casing.

また、上側仕切板4は、冷却器31とケーシング16に係合しているため、冷却器31及び送風装置13の下部を容易に開放でき、メンテナンス性が向上する。   Further, since the upper partition plate 4 is engaged with the cooler 31 and the casing 16, the lower portions of the cooler 31 and the blower 13 can be easily opened, and the maintainability is improved.

図8を用いて空気流Vの流れを説明する。   The flow of the air flow V will be described with reference to FIG.

送風部10のファン駆動部12が駆動して送風装置13が回転駆動する。収納室3内の空気は、吸気口41から吸引され冷却器31内を通過し、必要に応じて冷却され、上側仕切板4に設けられた吸気導入ダクト45をから吸気部14に吸引される。吸引された空気は送風装置13の吐出側に設けられた吐出部15から加熱部20に送り込まれる。   The fan drive unit 12 of the blower unit 10 is driven to rotate the blower 13. The air in the storage chamber 3 is sucked from the intake port 41, passes through the cooler 31, is cooled if necessary, and is sucked into the intake section 14 from the intake introduction duct 45 provided on the upper partition 4 . The suctioned air is sent from the discharge unit 15 provided on the discharge side of the blower 13 to the heating unit 20.

冷却器31と送風装置13は、天井壁7と略並行配列され、送風装置13の吸気部14は冷却器31側ではなく下方に向け開口しているが、上側仕切板4に設けられた吸気導入ダクト45により送風装置13の下方へ誘導されるので、上側仕切板と4と天井壁7との上側循環ダクト61内を流れる空気流Vは安定してスムーズに流れる。   The cooler 31 and the blower 13 are arranged substantially in parallel with the ceiling wall 7, and the intake portion 14 of the blower 13 is opened not downward but toward the cooler 31. However, the intake provided in the upper partition plate 4 The air flow V flowing in the upper circulation duct 61 of the upper partition plate 4 and the ceiling wall 7 stably and smoothly flows because the air is guided to the lower side of the blower 13 by the introduction duct 45.

また、送風部10の吐出部15は加熱部20と連通しているため、直接加熱部20に流れ、加熱部20に送り込まれた空気は必要に応じて加熱ヒータ21で加熱され、背面仕切板5の吹出し孔51から収納室3に排出される空気流Vが形成される。   Moreover, since the discharge part 15 of the ventilation part 10 is connected with the heating part 20, it flows to the heating part 20 directly, and the air sent into the heating part 20 is heated by the heater 21 as needed, and a back surface partition plate An air flow V discharged to the storage chamber 3 from the blowout holes 51 of 5 is formed.

加熱部20の加熱ヒータ21は、筐体2の背面壁2bの立設方向と略平行に配置される背面仕切板5と略平行に上下方向に延びるように画定されているため、加熱部20を通過する空気流Vは抵抗なく背面循環ダクト62内を流れる。背面循環ダクト62に流れる空気流Vは安定して背面循環ダクト62の下部まで行き渡り、各棚9に載置された加熱対象物Kを複数の吹出し孔51を介してまんべんなく加熱又は冷却し、吹出し孔51から収納室3の複数の棚9を通過して吸気口41に空気流Vを導く第1の循環流65を形成する。   The heating heater 21 of the heating unit 20 is defined so as to extend in the vertical direction substantially in parallel with the back surface partition plate 5 disposed substantially in parallel with the standing direction of the back surface wall 2 b of the housing 2. The air flow V passing through flows in the back circulation duct 62 without resistance. The air flow V flowing to the back circulation duct 62 stably spreads to the lower part of the back circulation duct 62, and uniformly heats or cools the heating target K placed on each shelf 9 through the plurality of blowout holes 51 and blows out. A first circulating flow 65 is formed which leads the air flow V from the hole 51 to the air inlet 41 through the plurality of shelves 9 of the storage chamber 3.

背面循環ダクト62の下側に設けられている風量調整部52の開口52bから吹き出された空気流Vは、最下段の棚9の下側にある収納室3の底部3aに形成された誘導凹部3bに導かれる。誘導凹部3bにより、吹出し孔51から届きにくい収納室3の前部に空気流Vを誘導することができる。そして、前部に誘導された空気流Vは収納室3の上側に向け流動する。風量調整部52から収納室3の底部3a及び前部を通過して吸気口41に空気流Vを導く第2の循環流66が形成される。   The air flow V blown out from the opening 52b of the air flow rate adjustment unit 52 provided on the lower side of the rear circulation duct 62 is a guiding recess formed on the bottom 3a of the storage chamber 3 below the lowermost shelf 9. It is led to 3b. The air flow V can be guided to the front of the storage chamber 3 which is hard to reach from the blowout hole 51 by the guiding recess 3 b. Then, the air flow V induced to the front flows toward the upper side of the storage chamber 3. A second circulating flow 66 is formed which leads the air flow V from the air flow adjustment unit 52 to the air inlet 41 through the bottom 3 a and the front of the storage chamber 3.

上述の第1の循環流65と第2の循環流66により収納室3全体に空気流Vを循環させることができる。即ち、背面仕切板5に近い後方の加熱対象物Kは吹出し孔51から上下均等に吹き出される空気流Vにより加熱又は冷却され、開閉扉6に近い前方の加熱対象物Kは、風量調整部52から吹き出され収納室3の前部で吸気口41に向かって上昇する空気流Vにより加熱又は冷却され、各棚9に載置された複数の加熱対象物Kは上下だけでなく前後にもムラなく均一に加熱又は冷却される。   The air flow V can be circulated throughout the storage room 3 by the first circulation flow 65 and the second circulation flow 66 described above. That is, the heating object K at the rear near the rear partition plate 5 is heated or cooled by the air flow V blown out evenly from the blowout hole 51, and the heating object K at the front near the opening and closing door 6 is the air volume adjusting portion The plurality of heating objects K which are blown out from 52 and heated or cooled by the air flow V rising toward the inlet 41 at the front of the storage chamber 3 are placed not only in the upper and lower sides but also in the front and back It is uniformly heated or cooled uniformly.

また、風量調整部52の開口面積により、収納室3の前部と後側との空気流Vのバランスが決定される。開口面積を大きくすると収納室3の後側の風量が弱まり、収納室3の前部への風量が強められ、開口面積を小さくすると、収納室3の後側の風量が強まり、収納室3の前部への風量が弱まる。収納室の大きさや形状等により適宜決定される。   Further, the balance of the airflow V between the front and rear sides of the storage chamber 3 is determined by the opening area of the air volume adjustment unit 52. When the opening area is increased, the air volume at the rear of the storage room 3 is weakened, the air volume to the front of the storage room 3 is intensified, and when the opening area is decreased, the air volume at the rear of the storage room 3 is increased. The air flow to the front is reduced. It is appropriately determined by the size, shape, etc. of the storage room.

以下、本発明の加熱調理装置1の動作を説明する。   Hereinafter, the operation of the heating and cooking apparatus 1 of the present invention will be described.

制御盤Sをセットして運転を開始すると、ファン駆動部12の駆動により送風装置13が回転する。送風部10の吸気部14が負圧となり、上側循環ダクト61の吸気口41から収納室3前部の空気を引き込む。送風装置13は、吸引した空気を吐出部15から背面循環ダクト62に送り込む。背面循環ダクト62に送り込まれた空気は、背面仕切板5に開口した吹出し孔51より各棚9に向け吹き出される。さらに風量調整部52の開口52bから最下段の棚9より下方に向け吹き出される。   When the control panel S is set and the operation is started, the blower 13 is rotated by the drive of the fan drive unit 12. The intake section 14 of the blower section 10 has a negative pressure, and the air at the front of the storage chamber 3 is drawn in from the intake port 41 of the upper circulation duct 61. The blower 13 sends the sucked air from the discharge unit 15 to the back circulation duct 62. The air fed into the rear circulation duct 62 is blown out to the respective shelves 9 from the blowout holes 51 opened in the rear partition plate 5. Furthermore, the air is blown downward from the lowermost shelf 9 from the opening 52 b of the air flow rate adjustment unit 52.

背面循環ダクト62の下方で吹き出しやすい空気流Vは、風量調整部52に抑制板52aがあるため下方への吹き出しを抑え、吹出し孔51から各棚9へ向け多く吹き出される。棚9に向け上下に複数開口した吹出し孔51は、背面循環ダクト62内の送風方向の下流側で吹き出しが多くなる下方の吹出し孔51の開口面積を小さくしているので、吹き出し量が下方に偏ることなく、上下均等に吹き出される。   The air flow V that easily blows out below the rear circulation duct 62 is suppressed from blowing downward because the air flow rate adjustment unit 52 includes the suppression plate 52 a, and is blown out toward the respective shelves 9 from the blowout holes 51. A plurality of blowout holes 51 opened upward and downward toward the rack 9 reduce the opening area of the blowout holes 51 below which the blowout increases on the downstream side in the blowing direction in the rear circulation duct 62, so the blowout amount is downward It blows up and down evenly without being biased.

風量調整部52から吹き出された風は、収納室3の底部3aに沿って前方に誘導される。収納室3の底部3aの前後方向に形成された誘導凹部3bにより、スムーズに誘導される。収納室3の前部に誘導された空気流Vは上方へ向け流動するが、上側循環ダクト61の吸気口41が収納室3の前部に開口しているので、収納室3の前部において上方へスムーズに流動できる。そして、収納室3の空気流Vは送風装置13の回転により、吸気口41から上側循環ダクト61を通過し送風装置13に吸引される。   The wind blown out from the air flow rate adjustment unit 52 is guided forward along the bottom 3 a of the storage room 3. It is smoothly guided by the guide recessed part 3b formed in the front-back direction of the bottom part 3a of the storage chamber 3. As shown in FIG. The air flow V guided to the front of the storage chamber 3 flows upward, but since the intake port 41 of the upper circulation duct 61 is open at the front of the storage chamber 3, It can flow smoothly upward. Then, the air flow V of the storage chamber 3 passes through the upper circulation duct 61 from the intake port 41 by the rotation of the blower 13 and is sucked by the blower 13.

そして、送風装置13により背面循環ダクト62へ送り込まれた空気は、各棚9に向けた吹出し孔51から上段から下段まで均等に吹き出し、棚9間を水平方向に流動する。そして、勢いが弱まると収納室3の上側に開口された吸気口41に向け流動し、再び上側循環ダクト61に吸引される。   And the air sent into the back surface circulation duct 62 by the air blower 13 blows out equally from the upper stage to the lower stage from the blowout holes 51 directed to the respective racks 9 and flows horizontally between the racks 9. Then, when the force becomes weak, the fluid flows toward the air inlet 41 opened to the upper side of the storage chamber 3 and is sucked again by the upper circulation duct 61.

一方、背面循環ダクト62の下方に流動した空気流Vは、収納室3の後側にある筐体2の背面壁2bとによるスリット状の開口52bから、棚9の最下段より下方に向け吹き出される。収納室3の底部3aの誘導凹部3bにより収納室3の前部(前方)まで同じ幅Dのままスムーズに空気流Vが誘導される。前部に誘導されると上方へ向け誘導され、収納室3の前部を通過する。そして、収納室3の前部の上側に開口した吸気口41に向け流動する。   On the other hand, the air flow V which has flowed to the lower side of the rear circulation duct 62 is blown downward from the lowermost stage of the shelf 9 from the slit-like opening 52b with the rear wall 2b of the housing 2 on the rear side of the storage chamber 3. Be done. The air flow V is smoothly induced to the front (the front) of the storage chamber 3 with the same width D by the guide recess 3 b of the bottom 3 a of the storage chamber 3. When guided to the front, it is directed upward and passes through the front of the storage room 3. Then, the air flows toward the air inlet 41 opened to the upper side of the front of the storage chamber 3.

上述の背面循環ダクト62によって、収納室3には、背面循環ダクト62から収納室3の後方へ吹き出される空気流Vの第1の循環流65と、背面循環ダクト62から収納室3の前部へ誘導される空気流Vの第2の循環流66との2つの循環流が収納室3全体にわたり形成されるため、収納室3の複数の棚9に載置された加熱対象物(食材)Kを上下だけでなく前後にも均一に加熱または冷却することができる。   The first circulation flow 65 of the air flow V blown out from the rear circulation duct 62 to the rear of the storage chamber 3 by the rear circulation duct 62 described above and the front of the storage chamber 3 from the rear circulation duct 62 Since two circulating flows of the air flow V directed to the part and the second circulating flow 66 are formed over the entire storage chamber 3, the heating object (food material placed on the plurality of shelves 9 of the storage chamber 3) ) K can be uniformly heated or cooled not only up and down but also back and forth.

<制御盤Sでの設定>
あらかじめ制御盤Sには、保冷温度、再加熱開始時刻、再加熱室内温度、再加熱時間、必要に応じて湿度を設定しておく。保冷温度は例えば3℃に設定するのが望ましい。再加熱室内温度は加熱対象物(食材、食品等)Kに応じて例えば80℃から120℃に設定し、再加熱時間は加熱対象物Kの量に応じて例えば30分から120分に設定することができる。加熱対象物Kに差し込む芯温センサーを有している場合は、芯温が例えば75℃で1分以上加熱されるまで加熱するよう設定してもよい。加熱時の湿度は加熱対象物Kに応じて0%から100%まで設定することが可能である。
<Setting on control panel S>
In advance, in the control panel S, the cold storage temperature, the reheating start time, the reheating room temperature, the reheating time, and the humidity are set as needed. The cold storage temperature is preferably set to 3 ° C., for example. The temperature in the reheating room is set, for example, from 80 ° C. to 120 ° C. according to the heating object (food, food, etc.) K, and the reheating time is set, for example, from 30 minutes to 120 minutes according to the amount of heating object K Can. When the core temperature sensor inserted into the heating target K is provided, heating may be performed until the core temperature is heated, for example, at 75 ° C. for one minute or more. The humidity at the time of heating can be set from 0% to 100% depending on the heating object K.

<制御盤Sでの設定>
<保冷運転:冷却ユニットが載置されている場合>
開閉扉6を開け、予め冷却された調理済みの加熱対象物Kを収納室3に収納する。開閉扉6を閉じ、制御盤Sより運転を開始すると、保冷運転が開始される。ファン駆動部12の駆動により送風装置13が回転し、冷却ユニット30が駆動開始する。上側循環ダクト61の吸気口41から収納室3内の空気を吸引し、冷却ユニット30で冷風となり、背面循環ダクト62に送り込まれる。
<Setting on control panel S>
<Cold-cooling operation: When the cooling unit is placed>
The open / close door 6 is opened, and the preheated cooled heating object K is stored in the storage chamber 3. When the open / close door 6 is closed and the operation is started from the control panel S, the cold storage operation is started. The blower 13 is rotated by the drive of the fan drive unit 12, and the cooling unit 30 starts driving. The air in the storage chamber 3 is sucked from the intake port 41 of the upper circulation duct 61, and cool air is generated by the cooling unit 30 and is sent to the rear circulation duct 62.

背面循環ダクト62の背面仕切板5に開口した吹出し孔51より冷風が各棚9に向け均等に吹き出される。各棚9の加熱対象物Kのうち、中央および後方の加熱対象物Kは、各棚9を水平に流動する冷風により冷却される。一方、背面循環ダクト62の風量調整部52から吹き出した冷風は、収納室3の底部3aに沿って前部に誘導される。前部に誘導された冷風は、上方へ向け流動し、再び上側循環ダクト61に吸引される。そして各棚9の前方の食材は、上方へ流動する冷風により冷却される。   Cold air is blown out uniformly toward the shelves 9 from the blowout holes 51 opened in the back surface partition plate 5 of the back surface circulation duct 62. Of the heating objects K of each shelf 9, the heating objects K at the center and the rear are cooled by cold air flowing horizontally in each shelf 9. On the other hand, the cold air blown out from the air flow rate adjustment unit 52 of the back circulation duct 62 is guided to the front along the bottom 3 a of the storage room 3. The cold air guided to the front flows upward and is again drawn into the upper circulation duct 61. And the foodstuff in front of each shelf 9 is cooled by the cold wind which flows upward.

<再加熱運転>
再加熱開始時刻になったら、保冷運転が停止され、再加熱運転が開始される。冷却ユニット30を停止し、加熱ヒータ21を駆動する。吸気口41から吸引された収納室3の空気は加熱ヒータ21により加熱され熱風となり、背面循環ダクト62内を通過する。背面循環ダクト62の背面仕切板5に開口した吹出し孔51より熱風が各棚9に向け均等に吹き出される。
<Reheating operation>
When the reheating start time comes, the cooling operation is stopped and the reheating operation is started. The cooling unit 30 is stopped and the heater 21 is driven. The air in the storage chamber 3 sucked from the intake port 41 is heated by the heater 21 and becomes hot air, and passes through the back circulation duct 62. Hot air is uniformly blown out toward each shelf 9 from the blowout holes 51 opened in the back surface partition plate 5 of the back surface circulation duct 62.

各棚9の加熱対象物Kのうち、中央および後方の加熱対象物Kは、各棚9を水平に流動する熱風により加熱される。一方、背面循環ダクト62の風量調整部52から吹き出した熱風は、収納室3の底部3aに沿って前部に誘導される。前部に誘導された熱風は、上方へ向け流動し、再び上側循環ダクト61に吸引される。そして各棚9の前方の加熱対象物Kは、上方へ流動する熱風により加熱される。   Among the objects to be heated K of the respective shelves 9, the objects to be heated K at the center and the rear are heated by the hot air flowing in the respective shelves 9 horizontally. On the other hand, the hot air blown out from the air flow rate adjustment unit 52 of the back circulation duct 62 is guided to the front along the bottom 3 a of the storage room 3. The hot air guided to the front flows upward and is again drawn into the upper circulation duct 61. The heating target K in front of each shelf 9 is heated by the hot air flowing upward.

設定した再加熱時間まで加熱時間が経過した時、または芯温センサーの芯温が所定温度で所定時間経過した時、加熱ヒータ21及びファン駆動部12が停止し、開閉扉6を開いて加熱対象物Kが取り出される。このとき、室内温度を例えば約80℃に設定した保温運転を開始して、作業者が取り出すまで加熱ヒータ21及びファン駆動部12の駆動を継続して、加熱対象物Kを保温するようにしてもよい。   When the heating time has elapsed until the set reheating time, or when the core temperature of the core temperature sensor has reached a predetermined temperature for a predetermined time, the heater 21 and the fan drive unit 12 are stopped and the open / close door 6 is opened to be heated The object K is taken out. At this time, the heat retention operation in which the room temperature is set to, for example, about 80 ° C. is started, and the driving of the heater 21 and the fan drive unit 12 is continued until the worker takes it out to keep the heating object K warm. It is also good.

本実施形態の加熱調理装置1は背面仕切板5の対面側には開閉扉6があるため、各棚9の両側に吸込みダクトまたは吹出しダクトを設置することができない。本実施形態の加熱調理装置1は、収納室3の後側に背面循環ダクト62を設け、収納室3の底部3aに沿って前部まで風を誘導し、上方へ向けた空気流Vの循環を行うことで、前部での空気流Vの不足(加熱又は冷却の不足)を補うように作用している。   The heating and cooking apparatus 1 according to the present embodiment has the open / close door 6 on the opposite side of the back surface partition plate 5, and therefore the suction duct or the blowout duct can not be installed on both sides of each shelf 9. The heating and cooking apparatus 1 of the present embodiment is provided with a back circulation duct 62 on the rear side of the storage room 3 and guides the wind to the front along the bottom 3 a of the storage room 3 and circulates the air flow V directed upward. To compensate for the lack of air flow V at the front (lack of heating or cooling).

しかしながら、上側循環ダクト61と組み合わされて循環ダクト60を構成する他のダクトは、背面循環ダクト62のように収納室3の後側、すなわち収納室3の背面に必ずしも配置する必要はなく、例えば、収納室3の前面及び背面以外の他の側面にも配置することができる。よって、収納室3の一方の側面(背面を含む)に配置された「側面循環ダクト」と上側循環ダクト61とにより、循環ダクト60を構成することもできる。ここでいう「側面循環ダクト」は、背面循環ダクト62を含む。   However, the other ducts constituting the circulation duct 60 in combination with the upper circulation duct 61 do not necessarily have to be disposed on the rear side of the storage room 3, ie, the rear face of the storage room 3, like the rear circulation duct 62. , It can arrange also on other side surfaces other than the front of storage room 3, and the back. Therefore, the circulation duct 60 can also be configured by the “side circulation duct” and the upper circulation duct 61 disposed on one side surface (including the back surface) of the storage chamber 3. The “side circulation duct” referred to here includes the back circulation duct 62.

背面循環ダクト62が形成される場合、底部3aへ誘導された空気流は、収納室3の前部に向けて誘導される。より広い概念である側面循環ダクトが形成される場合、収納室3の底部3aへ誘導された空気流は、収納室3の他方の側面に向けて誘導されることになる。例えば、側面循環ダクトが収納室3の右側面に形成される場合、空気流は右側面から底部3aへ誘導された後、収納室3の左側面に向けて誘導される。この場合も、収納室3の一方の側面から他方の側面に向け循環する2つの循環流(第1の循環流65、第2の循環流66を90度横向きにしたもの)が形成され、複数の加熱対象物に対してムラのない均一の加熱又は冷却が行える。   When the back circulation duct 62 is formed, the air flow directed to the bottom 3 a is directed toward the front of the storage room 3. In the case where the side circulation duct, which is a broader concept, is formed, the air flow guided to the bottom 3 a of the storage chamber 3 is directed toward the other side of the storage chamber 3. For example, when the side circulation duct is formed on the right side surface of the storage chamber 3, the air flow is guided from the right side surface to the bottom 3 a and then directed to the left side surface of the storage chamber 3. Also in this case, two circulating flows (first circulating flow 65 and second circulating flow 66 90 degrees sideways) circulating from one side to the other side of the storage chamber 3 are formed, Uniform heating or cooling can be performed on the object to be heated.

以上詳述したように、加熱調理装置1に収納室3の一方の側面から他方の側面に向け循環する2つの循環流(第1の循環流65と第2の循環流66)を形成することにより、複数の加熱対象物Kに対してムラのない均一の加熱又は冷却が行える。例えば背面循環ダクト62の対面側に開閉扉6が配置され他の循環ダクトを設置できない場合でも、上下だけでなく前後にもムラのない均一の加熱又は冷却が行える。   As described in detail above, forming two circulating flows (a first circulating flow 65 and a second circulating flow 66) in the heating and cooking apparatus 1 circulating from one side to the other side of the storage chamber 3 Thus, uniform heating or cooling can be performed on the plurality of heating targets K without unevenness. For example, even when the open / close door 6 is disposed on the opposite side of the back surface circulation duct 62 and no other circulation duct can be installed, uniform heating or cooling without unevenness even in the top and bottom can be performed.

上述の上側仕切板4、背面仕切板5、ケーシング16等の形状や配置状態は、本実施形態に基づく一例であり、本実施形態に記載される形状に限定されない。冷却器31を通過した空気が送風装置13に無理なく吸引され、送風装置13の吐出側の吐出部15から加熱部20に安定して空気が流れ、背面循環ダクト62内をスムーズに流れる空気流Vが形成される循環ダクト60が生じれば良い。   The shapes and arrangement states of the upper side partition plate 4, the back surface partition plate 5, the casing 16 and the like described above are an example based on the present embodiment, and are not limited to the shapes described in the present embodiment. The air that has passed through the cooler 31 is sucked by the air blower 13 without difficulty, and the air stably flows from the discharge portion 15 on the discharge side of the air blower 13 to the heating portion 20 and flows smoothly in the back circulation duct 62 It is only necessary to form a circulation duct 60 in which V is formed.

トレイ8に載置され、加熱される食品等を加熱対象物Kとして説明したが、本発明の特徴の一つとして加熱部20で空気が加熱する効率を重視しているためであり、用途により冷却される場合もあり、特に加熱のみに限定されない。   Although the food or the like placed on the tray 8 and heated is described as the heating object K, this is because the efficiency with which the air is heated in the heating unit 20 is emphasized as one of the features of the present invention. It may be cooled and is not particularly limited to heating.

尚、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数値、形態、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。   The present invention is not limited to the embodiments described above, and appropriate modifications, improvements, etc. are possible. In addition, the materials, shapes, dimensions, numerical values, forms, numbers, locations, etc. of the respective components in the above-described embodiment are arbitrary and not limited as long as the present invention can be achieved.

本発明に係る加熱調理装置は、空気流が安定して流れ、収納室内の加熱対象物が適切に加熱可能な空気流を図る食品配膳分野に適用可能である。   The heating and cooking apparatus according to the present invention can be applied to the field of food distribution where an air flow stably flows and an object to be heated in a storage room can appropriately heat an air flow.
