【発明の属する技術分野】
本発明は、病院やその他ホテルや学校で使用される配膳車の収容庫を、加温又は冷やすことによって温度調整した温度調整風を循環して温度調整する配膳車の温度調整風供給装置に関するものである。
【０００２】
【従来の技術】
病院等の施設において、各病室の患者への給食の配膳に、トレーに載置された食品セットを収容する複数の段を有する収容庫を備えた配膳車が使用されている。上記配膳車として、近年では収容庫が保温機能や保冷機能を備え、温かい食事を冷まさずに、あるいは冷たいものはそのままで配膳できるようにしたものが使用されている。このような配膳車としては、収容庫を区切って、ヒータで加温された温風を循環する保温室と、冷媒熱交換機で冷やされた冷風を循環する保冷室を備えたものが知られている（例えば、特開平８−３３５２４号公報等）。
【０００３】
上記温風又は冷風として温度調整した温度調整風を収容庫内に供給する温度調整風供給装置は、図４に示すように、収容庫内に設けられた吹出しダクト３４内で温度調整した温度調整風を、この吹出しダクト３４の上下複数個所に形成した吹出し口３３から供給するものである。上記温度調整風供給装置の吹出しダクト３４は、縦方向に仕切られており、中央側にヒータ又は冷媒熱交換機からなる温度調整器３９を有する温度調整風路３２、両側に吹出し口３３を有する送り出し路３１、温度調整風路３２と送り出し路３１を仕切って垂直方向に延設した仕切板３５、及び、下端部に温度調整風路３２と送り出し路３１を連通する連通路３６を備えるものである。なお、図中の符号３８は収容庫から吸風した吸い込みダクトの一部を示す。収容庫から吸い込みダクト３８で吸風した温度調整風は、温度調整風路３２を上側から下側に流れながら温度調整器３９で温度が調整されて連結路３６を通って送り出し路３１を下側から上側に流れると共に、各吹出し口３３から収容庫内に吹出される。
【０００４】
【発明が解決しようとする課題】
上記配膳車は、多数のトレーを収納することで配膳の効率を上げるため、収容庫に８〜１０段もの多数の段を設けているものが、採用されている。多数の段を設けた収容庫を有する配膳車にあっては、各段の温度をより均一に保つことが望まれているため、上記温度調整風供給装置は、各吹出し口３３から吹出される温度調整風の風速が均一であることが求められている。しかし、上記温度調整風供給装置は、送り出し路３１を流れる温度調整風の風量が各吹出し口から吹出される度に減量されるため、上段にいく程吹出される温度調整風の風速が小さくなり易い。そこで、各吹出し口の開口広さを調整したりすることが、試みられているが必ずしも満足できるものではなかった。
【０００５】
本発明は上記の事情に鑑みてなされたもので、その目的とするところは、多数の段を設けた収容庫を有する配膳車にあって、この収容庫の側面の上下複数個所に形成した吹出し口から各段に温度調整風を供給するものにおいて、収容庫の温度を均一に保つために、上記吹出し口から吹出される温度調整風の風速のばらつきをより少なくすることのできる配膳車の温度調整風供給装置を提供することにある。
【０００６】
【課題を解決するための手段】
請求項１記載の配膳車の温度調整風供給装置は、トレーに載置された食品を収容する複数の段を有すると共に加温又は冷やすことによって温度調整した温度調整風を循環して温度調整する収容庫を備えた配膳車であって、上記収容庫に縦方向に設けられて側面の上下複数個所に形成した吹出し口から各段に温度調整風を供給する吹出しダクトを有する配膳車の温度調整風供給装置において、上記吹出しダクトが、縦方向に仕切られており、その中央側に温度調整器を有する温度調整風路、両側に吹出し口を有する送り出し路、温度調整風路と送り出し路を仕切る仕切板、及び、下端部に温度調整風路と送り出し路を連通する連通路を備えると共に、上記送り出し路の断面積が連通路と接続した入口側から徐々に小さくなっていることを特徴とする。上記によって、温度調整風の風量が各吹出し口から吹出されて減量した程度に応じて送り出し路の温度調整風が流れる流路の断面積を徐々に小さくすることで、単位断面積当りに流れる風量を一定の水準に保つことができるので、吹出し口から吹出される温度調整風の風速のばらつきを小さくすることができるものである。
【０００７】
請求項２記載の配膳車の温度調整風供給装置は、トレーに載置された食品を収容する複数の段を有すると共に加温又は冷やすことによって温度調整した温度調整風を循環して温度調整する収容庫を備えた配膳車であって、上記収容庫に縦方向に設けられて側面の上下複数個所に形成した吹出し口から各段に温度調整風を供給する吹出しダクトを有する配膳車の温度調整風供給装置において、上記吹出しダクトが、縦方向に仕切られており、その中央側に温度調整器を有する温度調整風路、両側に吹出し口を有する送り出し路、温度調整風路と送り出し路を仕切る第１の仕切板、及び、下端部に温度調整風路と送り出し路を連通する連通路を備えると共に、上記送り出し路を縦方向に仕切ってその上端で折り返して往路と復路を形成すると共に上記吹出し口も略中央で往路と復路に仕切っている第２の仕切板を備えてなることを特徴とする。上記によって、吹出し口から往路を流れる温度調整風と復路を流れる温度調整風が吹出す風量が、往路は最下段の吹出し口の風量が多く、最上段の吹出し口の風量が少ないが復路はその逆となるため、各段の吹出し口から吹出される温度調整風の風量が平均化するので、吹出される温度調整風の風速のばらつきを小さくすることができるものである。
【０００８】
請求項３記載の配膳車の温度調整風供給装置は、請求項１又は請求項２記載の配膳車の温度調整風供給装置において、上記温度調整風が供給される収容庫が保温室であって、この保温室内に循環用ファンによって温度調整風路に備えたヒータで加温した温風を、送り出し路に形成した吹出し口から各段に供給することを特徴とする。上記によって、各段から吹出される温風の風速が安定しているので、上記温度調整風供給装置を備える配膳車は、保温室の温度を均一に保つことができるものである。
【０００９】
請求項４記載の配膳車の温度調整風供給装置は、請求項１又は請求項２記載の配膳車の温度調整風供給装置において、上記温度調整風が供給される収容庫が保冷室であって、この保温室内に循環用ファンによって温度調整風路に備えた冷媒熱交換機で冷やされた冷風を、送り出し路に形成した吹出し口から各段に供給することを特徴とする。上記によって、各段から吹出される冷風の風速が安定しているので、上記温度調整風供給装置を備える配膳車は、保冷室の温度を均一に保つことができるものである。
【００１０】
【発明の実施の形態】
本発明が使用されている配膳車の一例を図３に基づいて説明する。上記配膳車は、駆動装置を内蔵した病院等で使用される電動アシスト式のものであり、台車１９と、その上に固定された食品類を収容する複数の段を有する収容庫４を備えている。上記収容庫４は、四室設けられており、配膳車の前後の室に保温室４ａ、中央の二室に保冷室４ｂが備えられ、それぞれの保温室４ａと保冷室４ｂには、トレー１２に載置された食品類を出し入れするためのドア１３が、配膳車の両側の側面に設けられている。上記ドア１３は、ドア１３を開けることなく収容庫４内の状態を確認できるよう透明板で形成されている。なお、図３は、配膳車の右側一室のドア１３を開き、他の室のドア１３を閉じた状態を示すものである。上記収容庫４の保温室４ａや保冷室４ｂの温度測定されたデータは、上記ドア１３の上方に設けられた温度表示機１４にそれぞれ表示されるようにしてある。また、上記配膳車１は、その前面に走行をコントロールするハンドル１５を備え、このハンドル１５を用いて小さな操作力で動かせるように、電動アシスト機能を備えている。配膳車は、上記ハンドル１５の上方に、各種スイッチ１６を設けた操作パネル１７、及び、各種の情報を表示するモニター１８を備えている。
【００１１】
上記保温室４ａは、温風を循環して温度調整され、保冷室４ｂは、冷風を循環して温度調整されるものである。上記温度調整された温度調整風は、収容庫４に縦方向の複数個所に形成した吹出し口３から吹出されている。
【００１２】
次に、請求項１記載の温度調整風供給装置について説明する。図１は、請求項１に係る発明に対応する実施の形態の一例を示し、上記保温室４ａに温度調整風として温風を供給する温度調整風供給装置の内部を説明した概略図である。
【００１３】
上記温度調整風供給装置は、この収容庫４に縦方向に吹出しダクト１を設けており、この吹出しダクト１内で温度調整した温度調整風（温風）を、この吹出しダクト１の上下複数個所に形成した吹出し口３から供給するものである。上記温度調整風供給装置の吹出しダクト１は、縦方向に仕切られており、その中央側に温度調整風路６、両側に吹出し口３を有する送り出し路５、温度調整風路６と送り出し路５を仕切る仕切板２、及び、下端部に温度調整風路６と送り出し路５を連通する連通路７を備えている。また、図中の符号１１は収容庫４を循環した温度調整風を吸い込むため収容庫４の天井部に吸い込み口（図示せず）を形成したダクトの一部を示し、このダクト１１の基端部が温度調整風路６の上端と接続している。また、図中の符号１０は、温度調整風路６内に設置されたヒータである。さらに、上記温度調整風路６に温度検知機（図示せず）を取り付けており、ヒータ１０の強度を温度検知機の結果に基づいて適宜調整できるように形成しているものである。なお、図中の矢印は温度調整風の流れ方向を示す。
【００１４】
上記温度調整風供給装置は、上記仕切板２が、温度調整風路６の両側の側面を形成して略垂直方向に具備した垂直片２ａと送り出し路５の一方の側面を形成して傾斜片２ｂを備える。上記傾斜片２ｂは、下端が垂直片２ａと連接しており、上端が垂直片２ａと間隔を有している。上記温度調整風供給装置は、この傾斜片２ｂによって、上記送り出し路５を送り出し路５の断面積が連通路７と接続した入口側から徐々に小さくなるように形成している。送り出し路５の断面積は、温度調整風の風量が各吹出し口３から吹出されて減量した程度に応じて小さくしているものである。上記温度調整風供給装置は、送り出し路５の断面積を徐々に小さくなるように形成することで、送り出し路５を流れる単位断面積当りの風量を一定の水準に保つもので、このことで吹出し口３から吹出される温度調整風の風速がばらつきを小さくすることができるものである。その結果、上記温度調整風供給装置は、送り出し路５に形成した各段の吹出し口３から吹出される風速が安定するものである。したがって、上記温度調整風供給装置を備える配膳車は、各段から吹出される温風の風速が安定しているので、保温室４ａの温度を均一に保つことができるものである。
【００１５】
また、上記温度調整風供給装置は、保温室４ａに温風を供給する場合に限らず、保冷室４ｂの場合は、温度調整風路内にヒータに代わり冷媒熱交換機からなる温度調整器を設置すればよい。その結果、上記温度調整風供給装置は、送り出し路に形成した各段の吹出し口３から吹出される冷風の風速が安定するものである。したがって、上記温度調整風供給装置を備える配膳車は、各段から吹出される冷風の風速が安定しているので、保冷室４ｂの温度を均一に保つことができるものである。
【００１６】
また、収容庫を循環した温度調整風を吸い込むための吸い込み口は収容庫の天井部に形成してもよいし、温度調整風路６の上端に形成してもよい。
【００１７】
次に、請求項２記載の温度調整風供給装置について説明する。図２は、請求項２に係る発明に対応する実施の形態の一例を示し、内部を説明した概略図である。請求項１記載の温度調整風供給装置と異なるところのみを説明する。
【００１８】
上記温度調整風供給装置は、この収容庫４に縦方向に吹出しダクト１を設けている。上記吹出しダクト１は、縦方向に仕切られており、その中央側に温度調整風路６、両側に吹出し口３を有する送り出し路５、温度調整風路６と送り出し路５を仕切る第１の仕切板８、及び、下端部に温度調整風路６と送り出し路５を連通する連通路７を備えている。さらに、上記上記温度調整風供給装置は、第１の仕切板８が温度調整風路６の両側の側面を形成して略垂直方向に形成されており、第１の仕切板８の下端から略直角方向でダクトの外側に延設した水平板２０と、送り出し路５の中央付近で水平板２０の先端から連接して略垂直方向に立ち上がった第２の仕切板９を備えている。上記第２の仕切板９は、送り出し路５を縦方向に仕切ってその上端で折り返して往路５ａと復路５ｂを形成すると共に上記吹出し口３も略中央で往路５ａと復路５ｂに仕切っている。
【００１９】
上記温度調整風供給装置は、第２の仕切板９を備えているので、往路５ａは最下段の吹出し口３ａの風量が多く、徐々に減量されて最上段の吹出し口３ｂの風量が少っており、復路５ｂは最上段の吹出し口３ｂの風量が徐々に減量されて最下段の吹出し口３ａの風量が少なくなっている。その結果、上記温度調整風供給装置は、各段の吹出し口３から吹出される温度調整風の風量が平均化するので、吹出される温度調整風の風速のばらつきを小さくすることができるものである。したがって、上記温度調整風供給装置を備える配膳車は、各段から吹出される温度調整風の風速が安定しているので、収容庫４の温度を均一に保つことができるものである。上記温度調整風供給装置は、保温室４ａに温風を供給する場合、保冷室４ｂに冷風を供給する場合とも、同様に吹出す温度調整風の風速のばらつきを小さくすることができる。
【００２０】
【発明の効果】
請求項１記載の配膳車の温度調整風供給装置は、温度調整風の風量が各吹出し口から吹出されて減量した程度に応じて送り出し路の断面積を小さくすることで、単位時間当りに流れる風量を一定の水準に保つことができるので、吹出し口から吹出される温度調整風の風速のばらつきを小さくすることができる。
【００２１】
請求項２記載の配膳車の温度調整風供給装置は、各段の吹出し口から吹出される温度調整風の風量が平均化するので、吹出される温度調整風の風速のばらつきを小さくすることができる。
【００２２】
さらに、請求項３記載の配膳車の温度調整風供給装置は、特に、各段から吹出される温風の風速ばらつきが小さいものである。その結果、上記温度調整風供給装置を備える配膳車は、保温室の温度を均一に保つことができるものである。
【００２３】
さらに、請求項４記載の配膳車の温度調整風供給装置は、特に、各段から吹出される冷風の風速ばらつきが小さいものである。その結果、上記温度調整風供給装置を備える配膳車は、保冷室の温度を均一に保つことができるものである。

[0018]
The temperature adjusting wind supply device is provided with a blow-out duct 1 in the container 4 in the vertical direction. The blowout duct 1 is partitioned in the vertical direction, a temperature adjustment air passage 6 at the center side, a discharge passage 5 having a blowout port 3 on both sides, and a first partition that partitions the temperature adjustment air passage 6 and the discharge passage 5. A plate 8 and a communication path 7 communicating with the temperature adjusting air path 6 and the delivery path 5 are provided at the lower end. Furthermore, in the above temperature adjusting air supply device, the first partition plate 8 is formed in the substantially vertical direction by forming the side surfaces on both sides of the temperature adjusting air passage 6, and substantially from the lower end of the first partition plate 8. A horizontal plate 20 extending to the outside of the duct in a right angle direction and a second partition plate 9 rising from the front end of the horizontal plate 20 in the vicinity of the center of the delivery path 5 and rising in a substantially vertical direction are provided. The second partition plate 9 divides the delivery path 5 in the vertical direction and folds back at the upper end to form the forward path 5a and the return path 5b, and the blowout port 3 is also partitioned into the forward path 5a and the return path 5b at substantially the center.
[0019]
Since the temperature-controlled air supply device includes the second partition plate 9, the air flow at the lowermost outlet 3a is large in the forward path 5a, and the air volume at the uppermost outlet 3b is reduced gradually. In the return path 5b, the air volume at the uppermost outlet 3b is gradually reduced and the air volume at the lowermost outlet 3a is reduced. As a result, the temperature-adjusted air supply device averages the air volume of the temperature-adjusted air blown from the outlets 3 of each stage, so that the variation in the wind speed of the temperature-adjusted air that is blown out can be reduced. is there. Therefore, the layout vehicle equipped with the temperature-controlled wind supply device can keep the temperature of the container 4 uniform because the wind speed of the temperature-controlled wind blown from each stage is stable. The temperature-adjusted air supply device can reduce variations in the wind speed of the temperature-adjusted air that is blown out in the same manner when supplying warm air to the thermal insulation room 4a and supplying cold air to the cold room 4b.
[0020]
【The invention's effect】
The temperature-controlled wind supply device for a distribution vehicle according to claim 1 flows per unit time by reducing the cross-sectional area of the delivery path according to the degree to which the air volume of the temperature-controlled wind is blown out from each outlet and reduced. Since the air volume can be maintained at a constant level, it is possible to reduce the variation in the wind speed of the temperature-controlled air blown from the blow-out port.
[0021]
Since the air volume of the temperature-controlled wind blown from the outlets of each stage is averaged, the temperature-controlled wind supply device for the allocation vehicle according to claim 2 can reduce variations in the wind speed of the temperature-controlled wind blown out. it can.
[0022]
Furthermore, the temperature-adjusted wind supply device for a distribution vehicle according to claim 3 has particularly small variations in the wind speed of hot air blown from each stage. As a result, the distribution vehicle equipped with the temperature-controlled wind supply device can keep the temperature of the greenhouse constant.
[0023]
Furthermore, the temperature-regulated wind supply device for a garage according to claim 4 has particularly small variations in the wind speed of the cold wind blown from each stage. As a result, the distribution vehicle equipped with the temperature adjusting wind supply device can keep the temperature of the cold insulation room uniform.
