Description
本考案は,急速製氷および急速解氷による氷菓子製造装置に関し,より詳細には,製氷と解氷の切り替え操作を一つのバルブのみで容易に遂行できる急速製氷および急速解氷による氷菓子製造装置に関する。The present invention relates to an apparatus for producing ice confectionery by rapid ice making and rapid ice melting, and more specifically, an apparatus for producing ice confectionery by rapid ice making and rapid ice melting that can easily perform switching operation between ice making and ice melting with only one valve. About.
一般的に,冷蔵庫のような各種製氷装置を使用する時には,市販のファンタ,サイダーまたはコーラやジュースのような各種飲み物はもちろん,牛乳,コーヒ,ココア,緑茶などの各種茶類と,りんご,梨,ミカンなどの各種果物の汁,人参,大根などの野菜汁などを材料として氷菓子を製造する。場合によって,コンビニなどでは氷菓子製品を製造することができる別途の製氷器が使われている。In general, when using various ice making devices such as refrigerators, various drinks such as commercially available fanta, cider or cola and juice, as well as various teas such as milk, coffee, cocoa, green tea, apples, pears Ice confectionery is made from juices of various fruits such as mandarin oranges, vegetable juices such as carrots and radishes. In some cases, a separate ice maker that can produce ice confectionery products is used in convenience stores and the like.
しかし,このような各種製氷装置や製氷器は,シャーベット形態の製品を製造する機能に限定されているので,より高冷却を要求するアイスクリームやアイスケーキ形態の氷菓子を即時に製造するには問題があった。However, these types of ice making equipment and ice making machines are limited to the function of producing a sherbet-type product, so it is necessary to immediately produce ice cream and ice cake-type ice confections that require higher cooling. There was a problem.
また,一つの氷菓子製品を製造した直後に他種類の氷菓子製品を製造するためには,容器内の残余物を完全に除去して前の氷菓子製品の味が残らないように容器の表面に冷却された状態で付着している氷菓子残余物を完全に除去するためには相当時間と手間がかかるという問題があった。In addition, in order to manufacture other types of ice confectionery products immediately after manufacturing one ice confectionery product, the container must be completely removed so that the taste of the previous ice confectionery product does not remain. There is a problem that it takes a considerable amount of time and labor to completely remove the ice confectionery residue adhering to the surface in a cooled state.
従来の製氷装置や製氷器が持つ問題を解決して,即座に要求される氷菓子製品を製造できる急速製氷および急速解氷による氷菓子製造装置が公知となっている(例えば特許文献1)。図1に示されているように箱形ケース25の内部には,コンプレッサー11と凝縮器13,電子バルブ24aと膨張バルブ14および蒸発器12が冷媒配管により順次連結設置されて,コンプレッサー11と凝縮器13を連結する冷媒配管および凝縮器13と蒸発器12を連結する冷媒配管の間には,電子バルブ24を備えるバイパス管15が連結設置されて,蒸発器12はお盆の形態を有しながら,箱形ケース25の上部で露出される蒸発皿21の底部に平板形態の冷媒パイプ22を形成する。冷媒パイプ22の下部と外側全体面には冷媒パイプ22を覆う断熱材23を設置した。An ice confection manufacturing apparatus using rapid ice making and rapid ice thawing that can solve the problems of conventional ice making apparatuses and ice makers and that can immediately produce the required ice confectionery products is known (for example, Patent Document 1). As shown in FIG. 1, a compressor 11 and a condenser 13, an electronic valve 24 a, an expansion valve 14, and an evaporator 12 are sequentially connected and installed in the box-shaped case 25 by a refrigerant pipe. Between the refrigerant pipe connecting the condenser 13 and the refrigerant pipe connecting the condenser 13 and the evaporator 12, a bypass pipe 15 having an electronic valve 24 is connected and installed, and the evaporator 12 has a tray shape. A flat plate-shaped refrigerant pipe 22 is formed at the bottom of the evaporating dish 21 exposed at the top of the box-shaped case 25. A heat insulating material 23 covering the refrigerant pipe 22 was installed at the lower part of the refrigerant pipe 22 and the entire outer surface.
また,図2に示されているように,上記氷菓子製造装置に使われる蒸発皿の他の実施形態として,蒸発皿31の底部に設置される冷媒パイプ32を蒸発皿31と一体で形成して,その底部上に断熱材33が設置されるように構成された。図3および図4に示されているように,蒸発皿21,31の底部に設置される冷媒パイプ22,32には,ジグザグ形態の冷媒流路または水平多管式の冷媒流路が形成され設置された。As shown in FIG. 2, as another embodiment of the evaporating dish used in the ice confectionery manufacturing apparatus, a refrigerant pipe 32 installed at the bottom of the evaporating dish 31 is formed integrally with the evaporating dish 31. The heat insulating material 33 is installed on the bottom. As shown in FIGS. 3 and 4, the refrigerant pipes 22 and 32 installed at the bottoms of the evaporating dishes 21 and 31 are formed with zigzag refrigerant channels or horizontal multi-tube refrigerant channels. Was installed.
従って,最初バイパス管15に設置された電子バルブ24を閉めると同時に膨張バルブ14側の電子バルブ24aを開放させた状態でコンプレッサー11を作動させると,コンプレッサー11から凝縮器13と電子バルブ24aおよび膨張バルブ14を通った冷媒が蒸発器12を成す蒸発皿21,31の冷媒パイプ22,32に供給され,各種飲み物または果汁や野菜汁などの材料を即座に凍結させて,シャーベットやアイスクリームまたはアイスケーキなどの氷菓子を製造することができて,氷菓子の製造に使われた冷媒はコンプレッサー11に回収されて,次の氷菓子の製造に使用することができる。Accordingly, when the compressor 11 is operated with the electronic valve 24 installed on the bypass pipe 15 closed at the same time and the electronic valve 24a on the expansion valve 14 side opened, the compressor 13, the electronic valve 24a, and the expansion The refrigerant that has passed through the valve 14 is supplied to the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31 that constitute the evaporator 12, and various drinks or materials such as fruit juice and vegetable juice are immediately frozen to obtain sherbet, ice cream, or ice cream. Ice confectionery such as cake can be produced, and the refrigerant used for producing ice confectionery is recovered by the compressor 11 and can be used for production of the next ice confectionery.
また,このような氷菓子の製造過程で他の種類の氷菓子を連続して製造する場合,膨張バルブ14側の電子バルブ24aを閉めると同時に,バイパス管15に設置された電子バルブ24を開放させて,高温の冷媒ガスが蒸発皿21,31の冷媒パイプ22,32を通って直接供給させると,高温の冷媒ガスにより,蒸発皿21,31の表面についていた氷菓子製品の残余物を迅速かつ簡単に溶かして,除去することができる。これによって他の種類の氷菓子製品を短時間内に連続的に製造することができると同時に各氷菓子製品の味が互いに混ざらないようにすることができる。Further, when other types of ice confectionery are continuously manufactured in the process of manufacturing such ice confectionery, the electronic valve 24 installed on the bypass pipe 15 is opened simultaneously with closing the electronic valve 24a on the expansion valve 14 side. When the high-temperature refrigerant gas is supplied directly through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31, the ice confectionery product remaining on the surface of the evaporating dishes 21 and 31 is quickly removed by the high-temperature refrigerant gas. It can be easily melted and removed. As a result, other types of ice confectionery products can be produced continuously in a short time, and at the same time, the tastes of the ice confectionery products can be prevented from mixing with each other.
しかし,上述の氷菓子製造装置の場合は,製氷と解氷の操作を選択的に遂行できるようにするため,バイパス管15および膨張バルブ14が備わる冷媒配管上に各々1個の電子バルブ24,24aを設置するとともに,膨張バルブ14またその単価が比較的高価な電子式バルブを使用することになって,氷菓子製造装置の全体的な構造が多少複雑になり,同時に装置の製造単価を上昇させるという問題があった。これによって,多品種少量生産による小規模営業方式をする氷菓子製造業者に,より安い価格の氷菓子製造装置を供給することが難しくなるという問題があった。However, in the case of the ice confectionery manufacturing apparatus described above, one electronic valve 24, each on the refrigerant pipe provided with the bypass pipe 15 and the expansion valve 14 in order to selectively perform the ice making and ice melting operations. 24a is installed, and the expansion valve 14 and the electronic valve whose unit price is relatively expensive are used, so that the overall structure of the ice confectionery manufacturing apparatus becomes somewhat complicated, and at the same time, the unit manufacturing cost of the apparatus increases. There was a problem of letting. As a result, there is a problem that it is difficult to supply a cheaper ice confection manufacturing apparatus to an ice confectionery manufacturer that uses a small-scale sales method with a variety of small-quantity production.
また,箱形ケース25の外部にそれぞれの電子バルブ24,24aを個別的に作動させるスイッチ(ON amp;OFF Switch)等を設置する場合,該当スイッチが製氷と解氷中にどんな状況なのかを使用者が正確に把握して,装置を作動させる必要があって,氷菓子製造装置の操作に多少の混乱を招く問題があった。これを防止するために,該当スイッチの操作にともなう別途の案内表示や図案をケース25上に示す必要があるが,そのためにはまた追加費用が発生し,装置の製造単価面では望ましくないという問題があった。In addition, when a switch (ON amp; OFF Switch) that individually operates each electronic valve 24, 24a is installed outside the box-shaped case 25, it is possible to determine the status of the corresponding switch during ice making and ice melting. There is a problem that the user needs to know exactly and operate the apparatus, which causes some confusion in the operation of the ice confectionery manufacturing apparatus. In order to prevent this, it is necessary to display on the case 25 a separate guidance display or design associated with the operation of the corresponding switch. However, for this purpose, additional costs are incurred, which is not desirable in terms of the unit manufacturing cost of the device. was there.
上記氷菓子製造装置の操作にともなう使用者の不便と混乱を防止するための他の手段として,それぞれの電子バルブ24,24aを一つのスイッチで制御することもできるが,この場合にはスイッチと電子バルブ24,24aの間にPCBP(Printed circuit board;印刷回路基板)のような別途の電子制御部品が追加設置され,これもまた装置の製造価額の面から考えると,望ましくない。As another means for preventing the user's inconvenience and confusion associated with the operation of the ice confectionery manufacturing apparatus, each electronic valve 24, 24a can be controlled by a single switch. A separate electronic control component such as a printed circuit board (PCBP) is additionally installed between the electronic valves 24 and 24a, which is also not desirable from the viewpoint of the manufacturing cost of the apparatus.
特に,上記氷菓子製造装置を解氷状態で操作する場合,コンプレッサー11から吐出された高温の冷媒ガスが蒸発皿21,31の冷媒パイプ22,32を流動する過程で蒸発皿21,31を加熱させると同時に高温の冷媒ガスの中にその一部が凝縮されて,冷媒ガス中に液粒すなわち,液冷媒が発生される。そして過度な量の液冷媒はコンプレッサー11の作動オイルを希釈させて,ベアリングを損傷させてコンプレッサー11の内部で液圧縮を誘発させるようになる。そのため,コンプレッサー11に相当な負荷を与えて,氷菓子製造装置の作動中にコンプレッサー11が損傷するという問題があった。In particular, when the ice confectionery manufacturing apparatus is operated in an ice-free state, the evaporating dishes 21 and 31 are heated in the process in which the high-temperature refrigerant gas discharged from the compressor 11 flows through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31. At the same time, a part of the refrigerant gas is condensed in the high-temperature refrigerant gas, and liquid particles, that is, liquid refrigerant is generated in the refrigerant gas. An excessive amount of liquid refrigerant dilutes the working oil of the compressor 11, damages the bearings, and induces liquid compression inside the compressor 11. Therefore, there is a problem that the compressor 11 is damaged during operation of the ice confectionery manufacturing apparatus by applying a considerable load to the compressor 11.
上記のようにコンプレッサー11の内部で発生する液圧縮現象にともなうコンプレッサー11の負荷の負担を減らすために,上記氷菓子製造装置の技術内容のようにコンプレッサー11による解氷操作が形成される時間が一定時間を超過しないように別途のタイマーを設置して,コンプレッサー11の作動を制御することもありうるが,これもまた菓子製造装置の製造単価を上昇させる一つの要因になる。In order to reduce the load on the compressor 11 due to the liquid compression phenomenon that occurs inside the compressor 11 as described above, the time for the ice-breaking operation by the compressor 11 to be formed as in the technical contents of the ice confectionery manufacturing apparatus is formed. It is possible to control the operation of the compressor 11 by installing a separate timer so as not to exceed a certain time, but this is also one factor that raises the manufacturing unit price of the confectionery manufacturing apparatus.
そこで,本考案はこのような問題に鑑みてなされたもので,その目的とするところは,飲み物または果汁や野菜汁などの材料をお盆形態の蒸発皿で即座に凍結させて,シャーベットやアイスクリームまたはアイスケーキなどの氷菓子を製造できる急速製氷および急速解氷による氷菓子製造装置を提供することにある。Therefore, the present invention has been made in view of such problems. The purpose of the present invention is to instantly freeze drinks, fruit juices, vegetable juices, and other materials in a tray-shaped evaporating dish, and sorbet or ice cream. Alternatively, an object of the present invention is to provide an ice confection manufacturing apparatus by rapid ice making and rapid ice melting capable of producing ice confectionery such as ice cake.
また,他の種類の氷菓子を連続して製造する場合には,蒸発皿を速やかに加熱させて,蒸発皿についた氷菓子製品の残余物を簡単に溶かして,除去する急速製氷および急速解氷による氷菓子製造装置を提供することにある。Further, in case of continuously manufacturing other types of ice confections are allowed to promptly heat the evaporating dish, dissolved easily remainder of the ice confection products with evaporation dish, quick ice-making and removing An object of the present invention is to provide an ice confectionery manufacturing apparatus by rapid ice melting.
また,製氷と解氷の切り替え操作を一つのバルブのみで容易に遂行できて,装置の構造を単純化させてその製造単価を低下させ,使用者としても装置を簡単に操作できるようになり,コンプレッサーに再流入される冷媒ガスの中の液粒を効果的に分離させて,コンプレッサーの故障を未然に防止することもできる急速製氷および急速解氷による氷菓子製造装置を提供することにある。In addition, the switching operation between ice making and ice melting can be easily performed with only one valve, the structure of the device is simplified, the manufacturing unit price is reduced, and the user can operate the device easily. An object of the present invention is to provide an ice confection manufacturing apparatus by rapid ice making and rapid ice melting that can effectively separate liquid particles in refrigerant gas reflowed into the compressor and prevent the compressor from being broken.
上記課題を解決するために,本考案の観点によれば,コンプレッサーと凝縮器と蒸発器が冷媒配管により連結された状態で箱形ケースの内部に設置されて,コンプレッサーと凝縮器を連結する冷媒配管と凝縮器と蒸発器を連結する冷媒配管の間には電子バルブを備えるバイパス管が連結設置されて,蒸発器はお盆の形態を有しながら,ケースの上部で露出される蒸発皿の底部に冷媒パイプを形成する。また,冷媒パイプの下部と外側の全体面には冷媒パイプを覆う断熱材が設置されたことにおいて,凝縮器と蒸発器を連結する冷媒配管にはバイパス管が冷媒配管と連結する連結部の移転位置に毛細管が冷媒配管に沿って一体に連結設置されて,蒸発器とコンプレッサーを連結する冷媒配管にはコンプレッサーに流入する冷媒ガス中の液粒を分離させるための液分離器が設置される急速製氷および急速解氷による氷菓子製造装置が提供される。In order to solve the above problems, according to the aspect of the present invention, a compressor, a condenser, and an evaporator are installed inside a box-shaped case in a state of being connected by a refrigerant pipe, and a refrigerant that connects the compressor and the condenser is connected. A bypass pipe equipped with an electronic valve is connected between the pipe, the condenser and the refrigerant pipe connecting the evaporator. Form a refrigerant pipe. In addition, since heat insulating material covering the refrigerant pipe is installed on the lower and outer surfaces of the refrigerant pipe, the connection of the bypass pipe to the refrigerant pipe is transferred to the refrigerant pipe connecting the condenser and the evaporator. A capillary tube is integrally connected and installed along the refrigerant pipe at the position, and a liquid separator for separating liquid particles in the refrigerant gas flowing into the compressor is installed in the refrigerant pipe connecting the evaporator and the compressor. An ice confectionery manufacturing apparatus by ice making and rapid ice melting is provided.
以上説明したように本考案によれば,飲み物または果汁や野菜汁などの材料をお盆形態の蒸発皿で即座に凍結させて,シャーベットやアイスクリームまたはアイスケーキなどの氷菓子を製造できる。また,他の種類の氷菓子を連続して製造する場合には,蒸発皿を速やかに加熱させて,蒸発皿についていた氷菓子製品の残余物を簡単に溶かして除去できる。As described above, according to the present invention, ice confectionery such as sherbet, ice cream, or ice cake can be manufactured by instantly freezing a material such as drink or fruit juice or vegetable juice in a tray-shaped evaporating dish. Further, in case of continuously manufacturing other types of ice confections are allowed to promptly heat the evaporating dish can be removed easily dissolved residue of ices product was attached to the evaporating dish.
さらに,製氷と解氷の切り替え操作を一つのバルブのみで容易に遂行でき,これによって装置の構造を単純化させて,その製造単価も低下させ,使用者としてはより簡単に操作できるようになる。また,解氷作業を遂行してコンプレッサーに再流入される冷媒ガス中の液粒を液分離器で除去して,コンプレッサーの故障を未然に防止して,装置の製造単価低下にも大きく寄与する。In addition, the switching operation between ice making and ice melting can be easily performed with only one valve, which simplifies the structure of the device, lowers its manufacturing cost, and makes it easier for the user to operate. . In addition, by removing the liquid particles in the refrigerant gas re-flowing into the compressor after performing the de-icing operation, the compressor is prevented from malfunctioning, which greatly contributes to a reduction in the manufacturing cost of the equipment. .
以下に添付図面を参照しながら,本考案の好適な実施の形態について詳細に説明する。なお,本明細書及び図面において,実質的に同一の機能構成を有する構成要素については,同一の符号を付することにより重複説明を省略する。Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present specification and drawings, components having substantially the same functional configuration are denoted by the same reference numerals, and redundant description is omitted.
図5は,本考案による氷菓子製造装置を示す配管図で,図6のAおよびBは毛細管の望ましい形態を示す部分拡大図である。FIG. 5 is a piping diagram showing an ice confectionery manufacturing apparatus according to the present invention. FIGS. 6A and 6B are partially enlarged views showing a desirable form of a capillary tube.
本考案による急速製氷および急速解氷による氷菓子製造装置は,図5に示されているように,コンプレッサー11と凝縮器13と蒸発器12が冷媒配管により連結された状態で箱形ケース25の内部に設置されて,コンプレッサー11と凝縮器13を連結する冷媒配管および凝縮器13と蒸発器12を連結する冷媒配管の間には電子バルブ24を備えるバイパス管15が連結設置されて,蒸発器12はお盆の形態を有しながら,箱形ケース25の上部で露出する蒸発皿21の底部に平板形態の冷媒パイプ22を形成され,冷媒パイプ22の下部と外側全体面には冷媒パイプ22を覆う断熱材23が設置されている。As shown in FIG. 5, the ice confectionery manufacturing apparatus by rapid ice making and rapid ice melting according to the present invention has a box-shaped case 25 in a state where the compressor 11, the condenser 13, and the evaporator 12 are connected by a refrigerant pipe. A bypass pipe 15 having an electronic valve 24 is connected between a refrigerant pipe connecting the compressor 11 and the condenser 13 and a refrigerant pipe connecting the condenser 13 and the evaporator 12. 12 has a tray shape, and a flat plate-shaped refrigerant pipe 22 is formed at the bottom of the evaporating dish 21 exposed at the top of the box-shaped case 25. The refrigerant pipe 22 is formed at the lower part of the refrigerant pipe 22 and the entire outer surface. A covering heat insulating material 23 is installed.
また,蒸発皿は,先出願された氷菓子製造装置と同様に(図2に示されているように)蒸発皿31の底部に冷媒パイプ32が蒸発皿31と一体で形成され得るし,冷媒パイプ22,32からなる流路の構造も先出願された氷菓子製造装置と同様(図3,図4に示されているように)にジグザグ形態の流路や水平多管形態の流路を形成することもできる。In addition, the evaporating dish can be formed integrally with the evaporating dish 31 at the bottom of the evaporating dish 31 (as shown in FIG. 2), as in the ice confectionery manufacturing apparatus previously filed. The structure of the flow path composed of the pipes 22 and 32 is similar to that of the previously filed ice confection manufacturing apparatus (as shown in FIGS. 3 and 4), and has a zigzag flow path and a horizontal multi-tube flow path. It can also be formed.
そして,本考案の要部に該当する構成要素として,凝縮器13と蒸発器12を連結する冷媒配管には,該当冷媒配管の直径より多少小さい直径を持つ毛細管26が設置されるが,毛細管26はコンプレッサー11から凝縮器13を通りながらその温度が低下した凝縮冷媒を,蒸発器12を通して供給する前に,冷媒配管との直径差によって発生する圧力低下を利用して,凝縮冷媒を減圧された状態で供給する役割をする。そのために,電子式膨張バルブに比べて,その構造が非常に簡単で価格も下がると共に一つの配管形態で冷媒配管に沿って設置することが容易になる。As a component corresponding to the main part of the present invention, a capillary pipe 26 having a diameter slightly smaller than the diameter of the corresponding refrigerant pipe is installed in the refrigerant pipe connecting the condenser 13 and the evaporator 12. Before the condensed refrigerant having decreased in temperature while passing through the condenser 13 from the compressor 11 is supplied through the evaporator 12, the condensed refrigerant is depressurized by using the pressure drop generated by the diameter difference with the refrigerant pipe. It serves to supply in a state. Therefore, compared with an electronic expansion valve, the structure is very simple and the price is reduced, and it is easy to install along the refrigerant pipe in one pipe form.
また,毛細管26を通過した凝縮冷媒の減圧状態は,毛細管26の直径とその形状により非常に複雑で多様に形成されるので,毛細管26の直径はコンプレッサー11の容量による冷媒の吐出圧力に合わせて適切な毛細管を選択して使用することが望ましいが,凝縮器13と毛細管26を連結する冷媒配管に過度な内圧がかからないようにすると同時に毛細管26を通過した冷媒の質量流量が氷菓子の製造に十分な流量になるように,出来れば0.1 〜 0.6mm程度の毛細管を使用することが望ましい。In addition, the depressurized state of the condensed refrigerant that has passed through the capillary 26 is very complicated and varied depending on the diameter of the capillary 26 and its shape, so the diameter of the capillary 26 matches the refrigerant discharge pressure due to the capacity of the compressor 11. Although it is desirable to select and use an appropriate capillary tube, it is possible to prevent excessive internal pressure from being applied to the refrigerant piping connecting the condenser 13 and the capillary tube 26, and at the same time, the mass flow rate of the refrigerant passing through the capillary tube 26 is used for producing ice confectionery. If possible, it is desirable to use a capillary of about 0.1 to 0.6 mm so that the flow rate is sufficient.
また,図6のAおよびBに示されているように,毛細管26をスプリング形状や波形に屈曲させることにより冷媒の通過時間が掛かるようであれば,毛細管26の直径を0.6mmより多少大きくしても関係ない。しかし,毛細管26を直線形態に設置する場合には,その直径が0.1mm未満の微細管を使用すべきであり,毛細管26が設置される位置は,解氷操作時に毛細管26と冷媒配管の間で発生する圧力差により,高温の冷媒が蒸発皿21,31の冷媒パイプ22,32を通して,自然に流入できるようにバイパス管15が冷媒配管と連結される連結部の移転位置にしなければならない。Further, as shown in FIGS. 6A and 6B, if the capillary 26 is bent in a spring shape or a wave shape and the passage time of the refrigerant is increased, the diameter of the capillary 26 is slightly larger than 0.6 mm. It doesn't matter. However, when the capillary tube 26 is installed in a straight line shape, a fine tube having a diameter of less than 0.1 mm should be used, and the position where the capillary tube 26 is installed is located between the capillary tube 26 and the refrigerant pipe during the deicing operation. Due to the pressure difference generated between them, the bypass pipe 15 must be in the transfer position where the bypass pipe 15 is connected to the refrigerant pipe so that the high-temperature refrigerant can naturally flow through the refrigerant pipes 22 and 32 of the evaporating dishes 21 and 31. .
そして,コンプレッサー11を蒸発器12と連結する冷媒配管上には,コンプレッサー11から流入される冷媒ガスの中の液粒を分離させるための液分離器27が設置される。液分離器27(Accumulator)は,オイルと液冷媒の混合物を臨時に受け入れる貯蔵タンクの役割をすると同時に,オイルと液冷媒の混合物がコンプレッサー11を通して,器体状態の冷媒と安全な割合で流入するように計量してくれる役割をするため,できるだけコンプレッサー11の吸入側の近い位置に垂直に設置することが望ましい。And on the refrigerant | coolant piping which connects the compressor 11 with the evaporator 12, the liquid separator 27 for isolate | separating the liquid particle in the refrigerant gas which flows in from the compressor 11 is installed. The liquid separator 27 (Accumulator) acts as a storage tank that temporarily receives a mixture of oil and liquid refrigerant, and at the same time, the mixture of oil and liquid refrigerant flows through the compressor 11 at a safe rate with the refrigerant in the container state. Therefore, it is desirable to install it vertically as close to the suction side of the compressor 11 as possible.
以下,上記のような構成で形成される本考案の作用関係を,図5を参照して詳細に説明する。Hereinafter, the operational relationship of the present invention formed as described above will be described in detail with reference to FIG.
まず,蒸発皿21に氷菓子の材料,すなわち各種飲み物または果汁や野菜汁等を入れた後に,製氷する場合には,バイパス管15に設置された電子バルブ24を閉めると同時にコンプレッサー11を稼動させて,コンプレッサー11から凝縮器13と毛細管26および蒸発器12で形成される冷凍サイクルの冷媒配管に沿って冷媒が流動されるようにすると,蒸発器12を構成する蒸発皿21の冷媒パイプ22を通して,冷媒が流動されると同時に,冷媒が外部の熱を吸収しながら蒸発して,蒸発皿21に含まれた材料を急速に製氷させる。First, when ice confectionery materials, that is, various drinks or fruit juices, vegetable juices, etc., are put into the evaporating dish 21, the electronic valve 24 installed in the bypass pipe 15 is closed and the compressor 11 is operated simultaneously. When the refrigerant flows from the compressor 11 along the refrigerant pipe of the refrigeration cycle formed by the condenser 13, the capillary tube 26 and the evaporator 12, the refrigerant 11 passes through the refrigerant pipe 22 of the evaporating dish 21 constituting the evaporator 12. At the same time as the refrigerant flows, the refrigerant evaporates while absorbing external heat, and the material contained in the evaporating dish 21 is rapidly made into ice.
すなわち,冷媒がコンプレッサー11と凝縮器13および膨張バルブの役割をする毛細管26を経て,蒸発皿21の冷媒パイプ22に供給された後,コンプレッサー11に再流入される冷凍サイクルの循環過程で,凝縮器13の凝縮効率およびコンプレッサー11の圧縮効率が最大に維持され,蒸発皿21での急速冷却が可能になり,これによって蒸発皿21に入れられた各種氷菓子材料が即座に冷却されると同時に,冷媒パイプ22をかばっている断熱材23が熱損失を遮断して,シャーベットやアイスクリームまたはアイスケーキなどの氷菓子を速やかに製造できるようにする。That is, the refrigerant is supplied to the refrigerant pipe 22 of the evaporating dish 21 through the compressor 11, the condenser 13, and the capillary 26 that functions as an expansion valve, and then condensed in the circulation process of the refrigeration cycle that is re-flowed into the compressor 11. The condensing efficiency of the vessel 13 and the compression efficiency of the compressor 11 are maintained at the maximum, and rapid cooling in the evaporating dish 21 is enabled, whereby various ice confectionery materials placed in the evaporating dish 21 are immediately cooled. heat insulating material 23, which eaves refrigerant pipe 22 to block heat loss, to be manufactured promptly the ice confection, such as sherbets, ice cream or ice cakes.
上記のようにお盆形態で形成された蒸発皿21に氷菓子用材料を投入して本考案のシステムを作動させると,各種氷菓子材料が急冷しながら,通常数秒内に結氷して,シャーベットやアイスクリームまたはアイスケーキなどが製造できる。蒸発皿21に投入される材料の製氷温度,すなわち冷媒の蒸発温度を約−30℃ 程度に維持すると,製氷完了までに必要な時間は,約10秒程度である。薄氷形態のシャーベットはこれより短い製氷時間を要し,アイスクリームがその中間位に該当して,アイスケーキの場合が最も長い時間が要求される。When the ice confectionery material is put into the evaporating dish 21 formed in the tray shape as described above and the system of the present invention is operated, various ice confectionery materials are usually frozen within a few seconds while rapidly cooling, and sherbet or Ice cream or ice cake can be manufactured. If the ice making temperature of the material put into the evaporating dish 21, that is, the refrigerant evaporating temperature is maintained at about −30 ° C., the time required to complete ice making is about 10 seconds. Thin ice-shaped sherbet requires shorter ice making time, ice cream falls in the middle, and ice cake requires the longest time.
上記のように本考案による氷菓子製造装置を使用して,製氷作業を遂行する途中で,蒸発皿21に投入された材料と違う種類の氷菓子を製造するためには,一次的に蒸発皿21の表面に凍結付着された氷菓子製品の残余物を溶かして除去しなければならない。この場合には,バイパス管15に設置された電子バルブ24を開放させることで,コンプレッサー11から吐出された高温の冷媒が蒸発皿21の冷媒パイプ22を通して,直接流入される。これは毛細管26を通して自動的に達成できる。As described above, in order to manufacture an ice confection of a different type from the material put in the evaporating dish 21 during the ice making operation using the ice confection manufacturing apparatus according to the present invention, the evaporating dish is temporarily used. The residue of the ice confectionery product that has been frozen and adhered to the surface of 21 must be dissolved and removed. In this case, by opening the electronic valve 24 installed in the bypass pipe 15, the high-temperature refrigerant discharged from the compressor 11 flows directly through the refrigerant pipe 22 of the evaporating dish 21. This can be accomplished automatically through the capillary 26.
すなわち,バイパス管15に設置された電子バルブ24を開放させると,コンプレッサー11から吐出された冷媒の一部は凝縮器13を経て,毛細管26側に供給されて,その残りはバイパス管15を経て,蒸発皿21の冷媒パイプ22側と,毛細管26側に同時に供給されるが,凝縮器13は冷媒の温度を低下させるだけで冷媒の圧力状態にはほとんど変化がないため,毛細管26の両側にかかる冷媒の圧力は大きい差がない反面,蒸発器12と連結された冷媒配管の直径が毛細管26の直径より非常に大きくなり,毛細管26を通過した冷媒の流入が相対的に大きい抵抗を受けるようになる。これによってコンプレッサー11から吐出された冷媒が毛細管26を通して流入できなくなって蒸発皿21の冷媒パイプ22を通して自動的に流入される。That is, when the electronic valve 24 installed in the bypass pipe 15 is opened, a part of the refrigerant discharged from the compressor 11 is supplied to the capillary tube 26 side through the condenser 13 and the rest passes through the bypass pipe 15. , Are supplied simultaneously to the refrigerant pipe 22 side and the capillary tube 26 side of the evaporating dish 21, but the condenser 13 only lowers the temperature of the refrigerant and has almost no change in the pressure state of the refrigerant. Although the pressure of the refrigerant is not greatly different, the diameter of the refrigerant pipe connected to the evaporator 12 is much larger than the diameter of the capillary 26 so that the refrigerant flowing through the capillary 26 receives a relatively large resistance. become. As a result, the refrigerant discharged from the compressor 11 can no longer flow through the capillary 26 and automatically flows through the refrigerant pipe 22 of the evaporating dish 21.
また,これと共に蒸発皿21の冷媒パイプ22を通して流入される冷媒ガスは,凝縮器13および膨張バルブの役割をする毛細管26を経ない状態であるため,冷媒ガスが高温高圧の状態で維持されて,蒸発皿21の温度を速やかに上昇させられる。これによって蒸発皿21に凍結付着された氷菓子製品の残余物を非常に早く溶かして除去できる。また,蒸発皿21の加熱に使われた冷媒ガスは,その一部が凝縮された状態で蒸発器12の外部に排出された後,コンプレッサー11の吸入側に設置された液分離器27を経て,冷媒ガス中の液粒が除去された状態でコンプレッサー11を通して再流入される。In addition, the refrigerant gas that flows in through the refrigerant pipe 22 of the evaporating dish 21 does not pass through the condenser 13 and the capillary tube 26 that functions as an expansion valve, so that the refrigerant gas is maintained in a high temperature and high pressure state. and allowed to temperature promptly rises evaporating dish 21. As a result, the residue of the ice confectionery product freeze-adhered to the evaporating dish 21 can be melted and removed very quickly. The refrigerant gas used for heating the evaporating dish 21 is discharged to the outside of the evaporator 12 in a partially condensed state, and then passes through a liquid separator 27 installed on the suction side of the compressor 11. , The liquid particles in the refrigerant gas are removed and then re-inflowed through the compressor 11.
上記のように蒸発皿21に付着した氷菓子製品の残余物を除去した後には,上記のように,バイパス管15に設置された電子バルブ24を閉めて,上記装置が最初の冷凍サイクルに戻ると同時に,他の種類の氷菓子を蒸発皿21に新たに入れて製氷することができる。これによって新しく作られる氷菓子製品の味は前に製造した氷菓子製品の味と互いに混ざらないようなり,要求される風味の氷菓子製品を製造することができる。After removing the remaining ice confectionery product adhering to the evaporating dish 21 as described above, the electronic valve 24 installed in the bypass pipe 15 is closed as described above, and the apparatus returns to the first refrigeration cycle. At the same time, another type of ice confectionery can be newly put into the evaporating dish 21 for ice making. As a result, the taste of the freshly made ice confectionery product is not mixed with the taste of the previously produced ice confectionery product, and the desired flavored ice confectionery product can be produced.
上記のように本考案による氷菓子製造装置は,各種飲み物または果汁や野菜汁などの材料をお盆形態の蒸発皿21に入れた状態でコンプレッサー11と凝縮器13および毛細管26と蒸発器12で形成される冷凍サイクルを利用して,即座に凍結させられることで,シャーベットやアイスクリームまたはアイスケーキなどの各種氷菓子が簡単に製造できるし,他の種類の氷菓子を連続して製造する場合には,バイパス管15に設置された電子バルブ24を開放させて,蒸発皿21を速やかに加熱させることで蒸発皿21に付着していた氷菓子製品の残余物を簡単に溶かして除去できる。これによって以前に製造された氷菓子製品の味が新しく製造された氷菓子製品の味と互いに混ざらないようにできる。As described above, the ice confectionery manufacturing apparatus according to the present invention is formed by the compressor 11, the condenser 13, the capillary 26 and the evaporator 12 in a state where various drinks or materials such as fruit juice and vegetable juice are put in the tray-shaped evaporation dish 21. By using the refrigeration cycle, it is possible to easily produce various ice confections such as sherbet, ice cream or ice cake, and to continuously produce other types of ice confectionery. is it opens the electronic valve 24 installed in the bypass pipe 15 can be removed by dissolving easily remainder of the ice confection products having adhered to the evaporation dish 21 by causing promptly heat the evaporation dish 21 . This prevents the taste of previously produced ice confectionery products from being mixed with the taste of newly produced ice confectionery products.
また,本考案による氷菓子製造装置は,先出願された氷菓子製造装置とは違って,凝縮器13と蒸発器12を連結する冷媒配管に簡単な構造の毛細管26を設置して,毛細管26が膨張バルブと電子バルブの役割を同時に遂行できるようにすることで,氷菓子製造装置の全体的な構造を非常に単純化する。また,電子式バルブに該当する膨張バルブと電子バルブを使用しないことで,氷菓子製造装置の単価を低下させられる。これによって多品種少量生産による小規模営業方式をする氷菓子製造業者などに,より安価の氷菓子製造装置を供給することができる。The ice confectionery manufacturing apparatus according to the present invention is different from the previously filed ice confectionery manufacturing apparatus in that a capillary tube 26 having a simple structure is installed in the refrigerant pipe connecting the condenser 13 and the evaporator 12. Makes it possible to perform the roles of expansion valve and electronic valve at the same time, greatly simplifying the overall structure of the ice confectionery manufacturing equipment. Moreover, the unit price of the ice confectionery manufacturing apparatus can be reduced by not using the expansion valve and the electronic valve corresponding to the electronic valve. As a result, it is possible to supply a cheaper ice confectionery manufacturing apparatus to an ice confectionery manufacturer or the like that performs a small-scale sales method by small-lot production.
また,氷菓子製造装置による製氷および解氷操作を一つの電子バルブ24のみで容易に成し遂げられる。これによって箱形ケース25の外部に電子バルブ24を作動させるための一つのスイッチだけを設置すると,使用者が装置の製氷状態スイッチOFF状態と解氷状態スイッチON状態に混乱しないで装置を簡便に操作することができる。また,該当スイッチの操作にともなう別途の案内表示や図案を箱形ケース25上に示す必要がなく,スイッチと電子バルブ24の間に別途の電子制御部品を設置する必要がないため,装置の製造単価の低下にも寄与する。Further, the ice making and defrosting operations by the ice confectionery manufacturing apparatus can be easily accomplished by using only one electronic valve 24. Thus, if only one switch for operating the electronic valve 24 is installed outside the box-shaped case 25, the user can easily operate the apparatus without being confused by the ice making state switch OFF state and the deicing state switch ON state. Can be operated. Further, there is no need to display a separate guidance display or design associated with the operation of the corresponding switch on the box-shaped case 25, and it is not necessary to install a separate electronic control component between the switch and the electronic valve 24. It also contributes to lower unit prices.
特に,装置による解氷操作時コンプレッサー11から吐出された高温の冷媒ガスが蒸発皿21を加熱させると同時に高温の冷媒ガス中その一部が凝縮されて,冷媒ガスの中に液粒,すなわち液冷媒が発生しても,コンプレッサー11の吸入側に設置された液分離器27により,液粒が除去された状態の器体冷媒,またはコンプレッサー11に負荷がかからない適切な比率の液冷媒が混ざり合った器体冷媒をコンプレッサー11に流入されて,コンプレッサー11の故障を未然に防止することができる。これによって,先出願のようにコンプレッサー11の作動時間を制御する別途のタイマーを設置する必要がなくなり,装置の製造単価の低下により一層大きく寄与できる。In particular, the high-temperature refrigerant gas discharged from the compressor 11 during the ice-breaking operation by the apparatus heats the evaporating dish 21, and at the same time, a part of the high-temperature refrigerant gas is condensed, so that liquid particles, that is, liquid Even if the refrigerant is generated, the liquid separator 27 installed on the suction side of the compressor 11 mixes the liquid refrigerant in a state where the liquid particles are removed, or the liquid refrigerant in an appropriate ratio that does not apply a load to the compressor 11. It is possible to prevent the breakdown of the compressor 11 by flowing the body refrigerant into the compressor 11. As a result, it is not necessary to install a separate timer for controlling the operation time of the compressor 11 as in the prior application, which can further contribute to the reduction in the manufacturing cost of the apparatus.
上記説明した内容は箱形ケース25に一つの蒸発皿21が設置されたことを代表的な実施例としたが,先出願された氷菓子製造装置の技術内容と同じように,箱形ケース25の対面に複数個の蒸発皿21を設置した状態で,また他の毛細管26と電子バルブ24を使用して,それぞれの蒸発皿21が一つのコンプレッサー11と凝縮器13を共有する並列式冷凍サイクルで設置されることは,本考案が属する技術分野で通常の知識を持った者には自明な技術的事項であることは明白である。Although the above-described content is a typical embodiment in which one evaporating dish 21 is installed in the box-shaped case 25, the box-shaped case 25 is similar to the technical content of the previously filed ice confectionery manufacturing apparatus. A parallel refrigeration cycle in which each evaporating dish 21 shares one compressor 11 and condenser 13 by using a plurality of evaporating dishes 21 facing each other and using another capillary tube 26 and an electronic valve 24. It is obvious that it is a technical matter obvious to those who have ordinary knowledge in the technical field to which the present invention belongs.
以上,添付図面を参照しながら本考案の好適な実施形態について説明したが,本考案は係る例に限定されないことは言うまでもない。当業者であれば,実用新案登録請求の範囲に記載された範疇内において,各種の変更例または修正例に想到し得ることは明らかであり,それらについても当然に本考案の技術的範囲に属するものと了解される。As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It is obvious that a person skilled in the art can conceive various changes or modifications within the scope described in the claims for utility model registration, and these naturally belong to the technical scope of the present invention. It is understood.
