Description

本明細書では、アイスディスペンサに関する技術を開示する。   SUMMARY Disclosed herein are techniques related to ice dispensers.

従来、製氷された氷の貯氷量を所定の範囲に保持する技術が知られている。特許文献1には、製氷運転状況から貯氷庫内の貯氷量を算出して製氷する製氷機が開示されており、貯氷庫内の貯氷量は、「単位時間当たりの放水量」を減算し、「単位時間当たりの製氷量」を加算することにより算出される。そして、算出された貯氷量が上位作動値まで増加したときに製氷運転を停止し、下位作動値からさらに減少した所定の中間氷量値である閾値まで低下した場合に製氷運転を開始している。   Conventionally, a technique is known which holds the amount of stored ice in the ice made within a predetermined range. Patent Document 1 discloses an ice making machine that performs ice making by calculating the amount of stored ice in the ice storage based on the state of operation of ice making, and the amount of stored ice in the ice storage subtracts "the amount of water discharged per unit time" It is calculated by adding "the amount of ice making per unit time". Then, the ice making operation is stopped when the calculated ice storage amount increases to the upper operation value, and the ice making operation is started when the calculated ice storage amount decreases to the threshold value which is the predetermined intermediate ice amount value further decreased from the lower operation value. .

ところで、特許文献1の構成では、氷の需要が増加する繁忙期と氷の需要が減少する閑散期とのいずれの時期であるか否かに関わらず、「単位時間当たりの放水量」及び「単位時間当たりの製氷量」に基づいて貯氷量を所定の範囲に保持するため、ユーザによる製氷操作が多い繁忙期に貯氷量の不足により製氷が間に合わなくなったり、ユーザによる製氷操作が少ない閑散期に貯氷量が多すぎて無駄な製氷が多くなることが懸念される。   By the way, in the configuration of Patent Document 1, the “water discharge amount per unit time” and “the amount of discharged water per unit time” are used regardless of whether it is a busy period when the demand for ice increases or a slow period when the demand for ice decreases. In order to keep the amount of ice storage within a predetermined range based on the amount of ice making per unit time, during a busy period when there are many ice making operations by the user, ice making can not be made in time due to lack of ice making There is a concern that the amount of ice storage is too large and wasteful ice making increases.

本明細書に記載された技術は、上記のような事情に基づいて完成されたものであって、
繁忙期と閑散期との双方における貯氷量の過不足を抑制することが可能なアイスディスペンサを提供することを目的とする。
The technology described in the present specification has been completed based on the circumstances as described above,
An object of the present invention is to provide an ice dispenser capable of suppressing the excess or deficiency of the amount of stored ice in both the busy period and the low season.

本構成によれば、制御部がユーザによる氷の需要に応じて繁忙モードと閑散モードとを切り替えることにより、繁忙期の氷の不足や閑散期の無駄な製氷を抑制することが可能になる。よって、繁忙期と閑散期との双方における貯氷量の過不足を抑制することが可能となる。
The ice dispenser described in the present specification includes an ice making unit for making ice, an ice storage tank for storing ice made in the ice making unit, an outlet for releasing the ice stored in the ice storage tank, and the release port. And a control unit configured to control ice making by the ice making unit, wherein the control unit controls the amount of ice released from the discharge opening within a predetermined time. There is mode switching means for switching between the busy mode and the scattered mode in response, and in the scattered mode, ice making by the ice making unit is controlled so that the amount of stored ice in the ice storage tank is smaller than that in the busy mode.
According to this configuration, when the control unit switches between the busy mode and the sparse mode according to the demand for ice by the user, it is possible to suppress the shortage of ice in the busy period and the useless ice making in the rainy period. Therefore, it becomes possible to suppress the excess and deficiency of the amount of ice storage in both the busy period and the off season.

本明細書に記載された技術の実施態様としては以下の態様が好ましい。
前記操作部は、操作回数に応じた量の氷を前記放出口から放出させるものであり、前記制御部は、前記操作部の操作回数に応じて前記閑散モードと前記繁忙モードとを切り替える。
このようにすれば、氷の放出量を操作部の操作回数に応じて検知することが可能になるため、閑散モードと繁忙モードとの切り替えの処理を容易に行うことができる。
The following aspects are preferable as an embodiment of the technology described in this specification.
The operation unit is for releasing ice from the discharge port in an amount corresponding to the number of operations, and the control unit switches between the scattered mode and the busy mode according to the number of operations of the operation unit.
In this way, since the amount of released ice can be detected in accordance with the number of times of operation of the operation unit, it is possible to easily perform the process of switching between the sparse mode and the busy mode.

前記貯氷槽が満氷であることを検知する検知部を備え、前記制御部は、前記所定時間内における前記放出口からの氷の放出量が閾値以下であり、かつ、前記検知部が満氷であることを検知した際に、前記繁忙モードから閑散モードに切り替える。
このようにすれば、貯氷槽が満氷となった後に閑散モードとなるため、閑散モードにおける氷の不足を抑制することができる。
The detection unit includes a detection unit that detects that the ice storage tank is full, and the control unit is configured such that the amount of ice released from the discharge port within the predetermined time is equal to or less than a threshold, and the detection unit is full. When it is detected that the mode is switched from the busy mode to the discrete mode.
In this way, since the ice storage tank is in the scattered mode after the ice is full, it is possible to suppress the shortage of ice in the scattered mode.

流下した水が凍結することによりブロック形氷が板状に連結された形状の板形連結氷が製氷面に付着し、貫通孔が形成された製氷板と、前記貫通孔に挿通され、前記製氷板から前記板形連結氷が離脱する方向に前記板形連結氷を押し出す押し出し部と、前記板形連結氷の移動を検知する移動検知部と、前記貯氷槽に貯えられた氷を攪拌するように動作するアジテータと、ユーザにより第1設定と前記第1設定よりも前記貯氷槽に貯氷される氷の少ない第2設定とを切り替え可能な設定手段と、を備え、前記制御部は、前記第1設定に設定されている状態では、前記押し出し部の押し出し動作時において前記移動検知部が前記板形連結氷の移動を検知した後に前記アジテータを動作させ、前記第2設定に設定されている状態では、前記押し出し部の押し出し動作時において前記移動検知部が前記板形連結氷の移動を検知する前に前記アジテータを動作させる。
このようにすれば、ユーザの設定により、貯氷槽に貯氷される氷をアジテータが攪拌するタイミングを変えることができるため、貯氷槽に貯氷される氷の量をユーザの設定に応じて調節することができる。
When the water which has flowed down freezes, plate-shaped connected ice having a shape in which block-shaped ice is connected in a plate-like shape adheres to the ice making surface, and is inserted into the ice making plate having a through hole and the through hole. An extrusion unit for pushing out the plate-shaped connected ice in a direction in which the plate-shaped connected ice separates from the plate, a movement detecting unit for detecting the movement of the plate-shaped connected ice, and stirring the ice stored in the ice storage tank And a setting unit capable of switching between a first setting by the user and a second setting in which the amount of ice stored in the ice storage tank is smaller than the first setting. In the state set to 1 setting, the movement detection unit detects the movement of the plate-shaped connected ice at the time of the pushing operation of the pushing portion, and then the agitator is operated and the state set to the second setting So, said extrusion The movement detection section during the extrusion operation to operate the agitator before detecting the movement of the plate shaped connecting ice.
In this way, the timing at which the agitator agitates the ice stored in the ice storage tank can be changed according to the user's setting, so the amount of ice stored in the ice storage tank can be adjusted according to the user's settings. Can.

前記第2設定に設定されている状態で前記繁忙モードとなると、前記制御部は、前記移動検知部が前記板形連結氷の移動を検知する前に前記アジテータを動作させ、前記第2設定に設定されている状態で前記閑散モードとなると、前記制御部は、前記アジテータを動作させない。
このようにすれば、第2設定に設定されている状態における貯氷量の過不足を抑制することが可能となる。
When the busy mode is set with the second setting set, the control unit operates the agitator before the movement detecting unit detects the movement of the plate-shaped connected ice, thereby setting the second setting to the second setting. The control unit does not operate the agitator when the dispersed mode is set in the set state.
In this way, it is possible to suppress the excess or deficiency of the amount of stored ice in the state set to the second setting.

本明細書に記載された技術によれば、繁忙期と閑散期との双方における貯氷量の過不足を抑制することが可能となる。   According to the technology described in the present specification, it is possible to suppress excess or deficiency of the amount of stored ice in both the busy period and the off season.

実施形態1のアイスディスペンサ10について図1〜図10を参照しつつ説明する。
アイスディスペンサ10は、図1,図2に示すように、略直方体形状のハウジング11と、氷が製氷される製氷機構20と、製氷機構20により製氷された氷を貯える貯氷槽70と、貯氷槽70内に貯えた氷を容器台66に載置されたカップ等の容器に放出する放出機構90と、放出口92からの氷の放出をユーザが操作可能な操作部99とを備えている。
The ice dispenser 10 of Embodiment 1 will be described with reference to FIGS. 1 to 10.
The ice dispenser 10, as shown in FIGS. 1 and 2, includes a substantially rectangular housing 11, an ice making mechanism 20 in which ice is made, an ice storage tank 70 for storing ice made by the ice making mechanism 20, and an ice storage tank The release mechanism 90 releases the ice stored in the container 70 to a container such as a cup placed on the container table 66, and the operation unit 99 which allows the user to operate the release of the ice from the discharge port 92.

製氷機構20は、ハウジング11の上側に配置されており、氷を製氷する製氷部22と、製氷部22の下側に配置されて製氷水を貯えるタンク45とを備えている。製氷部22は、鉛直に起立し、前面を製氷面24とした浅い箱形の製氷板23と、製氷板23の製氷面24側に多数の製氷小室を形成する格子状の仕切り部材26とを備えている。製氷板23及び仕切り部材26は熱伝導性の良い銅板またはアルミニウム板が用いられている。製氷面24を流下する製氷水は凍結し、各製氷小室内で多数のブロック形に製氷される。各製氷小室内のブロック形氷は、隣り合う製氷小室内のブロック形氷と部分的に連結されているため、製氷板23の製氷面24側には、ブロック形氷が連結されて全体として板形の形状となった板形連結氷が形成される。   The ice making mechanism 20 is disposed on the upper side of the housing 11, and includes an ice making unit 22 for making ice, and a tank 45 provided below the ice making unit 22 for storing ice making water. The ice making section 22 stands vertically and has a shallow box-shaped ice making plate 23 whose front face is the ice making surface 24 and a grid-like partition member 26 forming many ice making chambers on the ice making side 24 of the ice making plate 23. Have. The ice making plate 23 and the partition member 26 use a copper plate or an aluminum plate having a good heat conductivity. The ice making water flowing down the ice making surface 24 freezes and is made into a large number of blocks in each ice making chamber. Since the block-shaped ice in each ice making chamber is partially connected to the block-shaped ice in the adjacent ice making chamber, the block-shaped ice is connected to the ice making surface 24 side of the ice making plate 23 to make a plate as a whole. Plate-shaped connected ice is formed in the shape of a shape.

製氷板23には、図5に示すように、貫通孔18が貫通形成されており、この貫通孔18に氷離脱装置50のスライドピン51(「押し出し部」の一例)が挿通可能となっている。貫通孔18は、製氷板23における左右方向の中間部で、上下方向の中間部よりも、やや上方側に形成されている。これにより、スライドピン51は、板形連結氷に対しては左右方向の中間部であって、上下方向の中間部よりもやや上側に当接して板形連結氷を製氷板23から離脱する方向に押し出し可能とされている。貫通孔18の後方には、スライドピン51のスライド方向を案内するガイド部材19が固定されている。ガイド部材19には、スライドピン51が挿通される挿通孔19Aが貫通形成されている。製氷板23の製氷面24と反対側には、図6に示すように、製氷部22としての冷凍装置30における蒸発管34と温度センサ38とが固定されている。   As shown in FIG. 5, a through hole 18 is formed through the ice making plate 23 so that the slide pin 51 (an example of the “push out portion”) of the ice detachment apparatus 50 can be inserted into the through hole 18. There is. The through hole 18 is formed at a middle portion in the left-right direction of the ice making plate 23, slightly above the middle portion in the vertical direction. As a result, the slide pin 51 is a middle portion in the left-right direction with respect to the plate-shaped connected ice, and abuts slightly above the middle portion in the vertical direction to separate the plate-shaped connected ice from the ice making plate 23 Can be pushed out. At the rear of the through hole 18, a guide member 19 for guiding the sliding direction of the slide pin 51 is fixed. An insertion hole 19A through which the slide pin 51 is inserted is formed through the guide member 19. On the opposite side of the ice making surface 24 of the ice making plate 23, as shown in FIG. 6, an evaporation tube 34 and a temperature sensor 38 in the freezing device 30 as the ice making unit 22 are fixed.

冷凍装置30は、冷媒を圧縮する圧縮機31と、圧縮した冷媒ガスをファン42の送風により冷却して液化させる凝縮器32と、液化冷媒を膨張させる膨張弁33と、膨張させた液化冷媒を気化させて製氷板23を冷却する蒸発管34とを備え、これらは冷媒管によって連結されて冷媒が循環する冷凍回路(冷媒回路)となっている。また、冷凍装置30は、冷凍回路に混入した水分を除去するためのドライヤ35と、圧縮機31と蒸発管34との間を接続するバイパス管36とを備え、バイパス管36にはホットガス弁37が介装されている。冷媒管における蒸発管34の入口部分及び出口部分やドライヤ35と凝縮器32との間には冷媒の温度を検知するための温度センサ39が固定されている。製氷機構20で製氷運転するときに、冷凍装置30のホットガス弁37を閉止させた状態で圧縮機31を作動させると、液化冷媒は蒸発管34で気化して製氷板23と仕切り部材26が冷却される。製氷板23の製氷面24側を流下する製氷水は冷却された製氷板23と仕切り部材26とにより冷却され、製氷水は製氷板23の製氷面24側で凍結して氷となる。   The refrigerating apparatus 30 includes a compressor 31 for compressing a refrigerant, a condenser 32 for cooling and compressing the compressed refrigerant gas by blowing air from a fan 42, an expansion valve 33 for expanding the liquefied refrigerant, and an expanded liquefied refrigerant. And an evaporation pipe 34 for vaporizing and cooling the ice making plate 23, which are connected by a refrigerant pipe to form a refrigeration circuit (refrigerant circuit) in which the refrigerant circulates. In addition, the refrigeration apparatus 30 includes a dryer 35 for removing water mixed in the refrigeration circuit, and a bypass pipe 36 connecting the compressor 31 and the evaporation pipe 34. The bypass pipe 36 is a hot gas valve 37 are interposed. A temperature sensor 39 for detecting the temperature of the refrigerant is fixed between the inlet and the outlet of the evaporation pipe 34 in the refrigerant pipe and between the dryer 35 and the condenser 32. When operating the ice making operation by the ice making mechanism 20, when the compressor 31 is operated with the hot gas valve 37 of the freezing apparatus 30 closed, the liquefied refrigerant is vaporized in the evaporation pipe 34 and the ice making plate 23 and the partition member 26 It is cooled. The ice making water flowing down the ice making surface 24 side of the ice making plate 23 is cooled by the cooled ice making plate 23 and the partition member 26, and the ice making water freezes on the ice making surface 24 side of the ice making plate 23 and becomes ice.

製氷機構20で除水運転をするときには、冷凍装置30のホットガス弁37を開放させた状態で圧縮機31を作動させると、圧縮機31から送られたホットガスが蒸発管34を通過させるときに製氷板23及び仕切り部材26を加温し、製氷板23の製氷面24側に製氷された氷は加温された製氷板23及び仕切り部材26との接触面で融解される。   When the water removal operation is performed by the ice making mechanism 20, when the compressor 31 is operated with the hot gas valve 37 of the refrigeration apparatus 30 open, the hot gas sent from the compressor 31 passes through the evaporation pipe 34 The ice making plate 23 and the partition member 26 are heated, and the ice made on the ice making surface 24 side of the ice making plate 23 is melted at the contact surface with the heated ice making plate 23 and the partition member 26.

図4,図5に示すように、製氷板23の製氷面24側には製氷面24側を流下させた製氷水が周囲に飛散するのを防ぐガイド板40が上端側を軸として所定角度回動可能に設けられている。ガイド板40及びハウジング11の少なくとも一方には、製氷面24側にて製氷された氷の製氷板23からの離脱や、貯氷槽70内が満氷状態であることを検知するための近接センサ等からなる検知部41(図6参照)が固定されている。製氷板23で製氷された板形連結氷がガイド板40に当接すると、ガイド板40が垂下姿勢から傾斜姿勢となるため、検知部41がガイド板40の位置を検知することにより、製氷された氷の製氷板23からの離脱を検知できる。また、貯氷槽70に落下した板形連結氷が貯氷槽70内で積み上がると、ガイド板40は積み上がった最上部の板形連結氷に当接して垂下姿勢に戻らずに傾斜姿勢を維持するため、検知部41がガイド板40の位置を検知することにより、貯氷槽70が満氷状態にあることを検知することができる。   As shown in FIGS. 4 and 5, on the ice making surface 24 side of the ice making plate 23, a guide plate 40 for preventing the ice making water flowing down the ice making surface 24 from splashing around is rotated a predetermined angle around the upper end side. It is provided to be movable. At least one of the guide plate 40 and the housing 11 is a proximity sensor or the like for detecting that the ice made on the side of the ice making surface 24 is detached from the ice making plate 23 or that the inside of the ice storage tank 70 is full. The detection unit 41 (see FIG. 6) is fixed. When the plate-shaped connected ice made by the ice making plate 23 abuts against the guide plate 40, the guide plate 40 changes from the hanging posture to the inclined posture, so that the detecting unit 41 detects the position of the guide plate 40 to make ice. It is possible to detect the detachment of the frozen ice from the ice making plate 23. In addition, when the plate-shaped connected ice dropped into the storage tank 70 is stacked in the storage tank 70, the guide plate 40 abuts on the stacked top-shaped connected ice and maintains the inclined posture without returning to the hanging posture. Therefore, when the detection unit 41 detects the position of the guide plate 40, it can be detected that the ice storage tank 70 is in a full ice state.

製氷板23の製氷面24側を流下する製氷水はタンク45に流れ落ちるようになっている。タンク45には、図6に示すように、水道などの給水源に接続した給水管48が接続されており、給水管48には給水弁49が設けられている。給水弁49の開放によって給水源の水は給水管48を通ってタンク45に供給される。タンク45内の製氷水は、製氷水回路60により循環される。製氷水回路60はタンク45内に設けた送水ポンプ61と、送水ポンプ61に接続された送水管62と、浮力で水位に合わせて上下変動し、送水をオンオフするフロートスイッチ47Bと、タンク45内の水温を検知する水温センサ47Aと、製氷板23の上側に配設されて送水管62に接続された散水器63とを備えている。また、送水管62の中間部には製氷水を容器台66に導く導水管64が接続されており、導水管64には排水バルブ65が設けられている。製氷運転をしたときに、タンク45内の製氷水は送水ポンプ61の駆動によって送水管62を通って散水器63に送られ、散水器63から製氷板23の製氷面24側を流下してタンク45に戻り、タンク45内の製氷水は製氷水回路60によってタンク45と製氷板23の製氷面24側とを循環する。タンク45内の製氷水は製氷面24で漸次凍結して仕切り部材26の中で氷となる。製氷運転後に残るタンク45内の製氷水は排水バルブ65の開放によって導水管64から容器台66に送られる。   The ice making water flowing down the ice making surface 24 side of the ice making plate 23 flows into the tank 45 and falls. As shown in FIG. 6, a water supply pipe 48 connected to a water supply source such as a water supply is connected to the tank 45, and the water supply pipe 48 is provided with a water supply valve 49. The water of the water supply source is supplied to the tank 45 through the water supply pipe 48 by the opening of the water supply valve 49. The ice making water in the tank 45 is circulated by the ice making water circuit 60. The ice making water circuit 60 has a water supply pump 61 provided in the tank 45, a water supply pipe 62 connected to the water supply pump 61, a float switch 47B for fluctuating the water up and down according to the water level, and the inside of the tank 45 The water temperature sensor 47A for detecting the water temperature of the water temperature sensor, and the sprinkler 63 disposed on the upper side of the ice making plate 23 and connected to the water supply pipe 62 are provided. Further, a water guiding pipe 64 for guiding the ice making water to the container table 66 is connected to an intermediate part of the water feeding pipe 62, and the water discharging pipe 64 is provided with a drainage valve 65. When the ice making operation is performed, the ice making water in the tank 45 is sent to the water sprayer 63 through the water supply pipe 62 by the drive of the water supply pump 61, and flows down the ice making surface 24 side of the ice making plate 23 from the water sprayer 63 Returning to 45, the ice making water in the tank 45 circulates through the tank 45 and the ice making surface 24 side of the ice making plate 23 by the ice making water circuit 60. The ice making water in the tank 45 is gradually frozen on the ice making surface 24 and becomes ice in the partition member 26. The ice making water in the tank 45 remaining after the ice making operation is sent from the water conduit 64 to the container stand 66 by opening the drain valve 65.

タンク45内には、図3に示すように、水位センサ46が設けられている。水位センサ46はタンク45内の製氷水の第1水位と第1水位より高い第2水位を検出するものである。水位センサ46により検出される第1水位は製氷板23にて製氷が完了したときのタンク45内の水位であり、第2水位は製氷板23の製氷面24側にて板形連結氷を製氷するのに必要なタンク45内の水位である。第2水位であったタンク45内の製氷水は製氷板23に板形連結氷が形成されると、第1水位まで減少するため、この水位の変化を水位センサ46が検出することにより、板形連結氷が形成されたことが検知される。板形連結氷が形成されたことが検知されると、送水ポンプ61の駆動を停止させるとともに、圧縮機31から送出されるホットガスを蒸発管34に送出させる。板形連結氷を製氷板23及び仕切り部材26との接触面で僅かに融かして製氷板23から離脱可能な状態にし、氷離脱装置50により板形連結氷を製氷板23から離脱させて貯氷槽70の内部に落下させる。   In the tank 45, as shown in FIG. 3, a water level sensor 46 is provided. The water level sensor 46 detects a first water level of ice making water in the tank 45 and a second water level higher than the first water level. The first water level detected by the water level sensor 46 is the water level in the tank 45 when ice making is completed by the ice making plate 23, and the second water level makes plate-shaped connected ice at the ice making surface 24 side of the ice making plate 23 The water level in the tank 45 required to The ice making water in the tank 45, which was at the second water level, decreases to the first water level when plate-shaped connected ice is formed on the ice making plate 23, so the water level sensor 46 detects the change in water level. It is detected that an interlocking ice has been formed. When it is detected that the plate-shaped connected ice is formed, the driving of the water supply pump 61 is stopped, and the hot gas delivered from the compressor 31 is delivered to the evaporation pipe 34. The plate-shaped connected ice is slightly melted at the contact surface with the ice making plate 23 and the partition member 26 so as to be detachable from the ice making plate 23, and the plate-shaped connected ice is released from the ice making plate 23 by the ice detaching device 50. Drop into the inside of the ice storage tank 70.

氷離脱装置50は、図5に示すように、製氷板23の後側に設けられており、製氷板23の貫通孔18に挿通されるスライドピン51を備えている。スライドピン51はモータ52の駆動によって回転するカムによって貫通孔18を貫通する方向にスライド移動可能とされている。モータ52は回転軸の回転角度を検出する角度検出センサを備えており、角度検出センサは回転軸に取り付けたエンコーダにより回転軸の回転角度を検出するようになっており、角度検出センサによりスライドピン51の押し出し位置を検知することができる。なお、図5では、スライドピン51について、製氷板23から板形連結氷を離脱させる押し出し位置まで進出した状態に符号51Aを付し、板形連結氷を押圧しない退避位置まで退避した状態に符号51Bを付している。   As shown in FIG. 5, the ice detaching device 50 is provided on the rear side of the ice making plate 23 and includes a slide pin 51 inserted through the through hole 18 of the ice making plate 23. The slide pin 51 is slidably moved in a direction passing through the through hole 18 by a cam rotated by the drive of the motor 52. The motor 52 is provided with an angle detection sensor for detecting the rotation angle of the rotation shaft, and the angle detection sensor is configured to detect the rotation angle of the rotation shaft by an encoder attached to the rotation shaft. 51 pushing positions can be detected. In FIG. 5, the slide pin 51 is attached with the reference numeral 51A in a state where it has advanced to the push-out position where the plate-shaped connected ice is separated from the ice making plate 23 and is in a state where it is retracted to the retracted position where the plate-type connected ice is not pressed. 51B is attached.

図2に示すように、貯氷槽70は製氷機構20にて製氷した氷を貯えるものであり、ハウジング11内にて製氷機構20の下則に配置されている。搬送機構75は貯氷槽70内の氷を放出機構90に搬送するものであり、搬送羽根76を回転させるモータ77と、筒体の下側に設けたモータ78と、筒体内に回転可能に支持されたオーガスクリュー80とを備えている。モータ77の出力軸にはアジテータ79が固定されている。アジテータ79は撹拌軸79Aと、撹拌軸79Aに対して交差する方向に延出された複数の撹拌棒79Bとを備えている。モータ77の駆動により搬送羽根76とともに撹拌軸79Aが回転すると、撹拌棒79Bは貯氷槽70内を回動して製氷機構20により製氷された板形連結氷をブロック形の氷に砕くとともに、貯氷槽70内に局部的に氷が貯まるのを防ぐようにしている。   As shown in FIG. 2, the ice storage tank 70 stores ice formed by the ice making mechanism 20, and is disposed within the housing 11 in accordance with the lower rule of the ice making mechanism 20. The transport mechanism 75 transports the ice in the ice storage tank 70 to the discharge mechanism 90, and supports the motor 77 for rotating the transport blade 76, the motor 78 provided below the cylinder, and the cylinder rotatably supported in the cylinder. And an auger screw 80. An agitator 79 is fixed to the output shaft of the motor 77. The agitator 79 includes a stirring shaft 79A and a plurality of stirring rods 79B extended in a direction intersecting with the stirring shaft 79A. When the stirring shaft 79A is rotated together with the conveying blade 76 by the driving of the motor 77, the stirring rod 79B rotates in the ice storage tank 70 to crush plate-shaped connected ice made by the ice making mechanism 20 into block-shaped ice It is intended to prevent accumulation of ice locally in the tank 70.

放出機構90は、搬送機構75により搬送された氷を定量してカップ等の容器に放出するものであり、ハウジング11の上部に設けた円柱形の定量室91を備える。定量室91の底部側には氷が放出される放出口92と所定量の氷を複数室に仕切る氷定量器91Aとが設けられている。氷定量器91Aは、モータ93の駆動力により氷を回動させるものであり、図3に示すように、定量室91に回動自在に支持された中心軸部94Aと、中心軸部94Aから放射状に延び、周方向に等間隔の6カ所の扇形定量空間を形成するセパレ一夕部94Bとを備えている。また、氷定量器91Aの上側には扇形定量空間の上側からはみ出る氷を除く除去装置71が設けられている。氷定量器91Aを例えば60°回動させると、1つ分の扇形定量空間内の氷が放出口92の上側に配され、放出口92から容器台66の容器に放出される。また、氷定量器91Aを例えば180°回動させると氷定量器91Aの3つ分の扇形定量空間内で定量された氷が放出口92の上側に移動し、定量された氷は放出口92から容器台66の容器内に放出される。放出口92からの氷の放出は、操作部99の操作に応じて行われる。操作部99は、図1に示すように、複数(本実施形態では3つ)の操作ボタンを備えており、それぞれ異なる量の氷が放出される。本実施形態では、各操作ボタンは、例えば、それぞれ1つ分、2つ分、3つ分の扇形定量空間を回転させるものであり、各操作ボタンの放出量は、例えば、100g,200g,300gとされる。   The discharge mechanism 90 quantifies the ice transported by the transport mechanism 75 and discharges it to a container such as a cup, and includes a cylindrical metering chamber 91 provided at the top of the housing 11. On the bottom side of the metering chamber 91, there are provided a discharge port 92 from which the ice is discharged and an ice metering device 91A for dividing a predetermined amount of ice into a plurality of chambers. The ice meter 91A is for rotating the ice by the driving force of the motor 93, and as shown in FIG. 3, from the central shaft 94A rotatably supported by the quantitative chamber 91, and from the central shaft 94A. It has a radial separation portion 94B which radially extends and forms six equally spaced fan-shaped measuring spaces in the circumferential direction. Moreover, the removal apparatus 71 except the ice which overflows from the upper side of the fan-shaped measurement space is provided above the ice measurement machine 91A. When the ice meter 91A is rotated, for example, by 60 °, the ice in one fan-shaped measurement space is disposed above the discharge port 92 and is discharged from the discharge port 92 to the container 66 container. In addition, when the ice meter 91A is rotated, for example, by 180 °, the ice quantified in the three fan-shaped measurement spaces of the ice meter 91A moves to the upper side of the discharge port 92, and the quantified ice is discharged Are discharged into the container of the container table 66. Discharge of the ice from the discharge port 92 is performed according to the operation of the operation unit 99. As shown in FIG. 1, the operation unit 99 includes a plurality of (three in the present embodiment) operation buttons, and different amounts of ice are released. In the present embodiment, each operation button rotates, for example, one, two, or three fan-shaped measurement spaces, and the discharge amount of each operation button is, for example, 100 g, 200 g, and 300 g. It is assumed.

Ice and water spilled from the container are received by the drain pan of the drainage channel, and ice and water received by the drain pan are drained out of the housing 11 through the drain pipe 97.

アイスディスペンサ10の電気的構成について図7を参照しつつ説明する。
アイスディスペンサ10は、図7に示すように、マイクロコンピュータ等からなる制御部100を備えており、制御部100は、タイマ101と、製氷部22による製氷を多くなるように制御する繁忙モードと繁忙モードよりも製氷部22による製氷が少なくするように制御する閑散モードとを切り替えるモード切り替え手段102とを有する。また、制御部100には、操作部99、設定手段104、電流センサ106(「移動検知部」の一例)、水位センサ46、検知部41、温度センサ38、圧縮機31、ホットガス弁37、送水ポンプ61、給水弁49、モータ52、77、93、氷定量器91A等が接続されている。
The electrical configuration of the ice dispenser 10 will be described with reference to FIG.
As shown in FIG. 7, the ice dispenser 10 includes a control unit 100 including a microcomputer and the like. The control unit 100 controls the timer 101 and the busy mode to control the ice making by the ice making unit 22 to increase ice making. It has mode switching means 102 which switches to the scattering mode controlled so that the ice making by the ice making part 22 may be made smaller than the mode. Further, the control unit 100 includes an operation unit 99, setting means 104, a current sensor 106 (an example of a "movement detection unit"), a water level sensor 46, a detection unit 41, a temperature sensor 38, a compressor 31, a hot gas valve 37, A water supply pump 61, a water supply valve 49, motors 52, 77, 93, an ice meter 91A, and the like are connected.

電流センサ106は、氷離脱装置50のスライドピン51を移動させるモータ52への供給電流を検知しており、モータ52への供給電流の低下により、板形連結氷が動き出してモータ52の負荷が減少したことを検知することができる。   The current sensor 106 detects the current supplied to the motor 52 for moving the slide pin 51 of the ice separation device 50, and the plate-type connection ice moves out due to the reduction of the current supplied to the motor 52, and the load of the motor 52 It can detect that it has decreased.

設定手段104は、ユーザが操作可能なスイッチとされており、ユーザにより第1設定と、第1設定よりも貯氷槽70に貯氷される氷の少ない第2設定と、を切り替え可能とされている。第1設定では繁忙モードと閑散モードのいずれにおいても制御部100は、常に貯氷槽70が満氷になるように製氷部22を制御する。そして、第1設定に設定されている状態では、繁忙モード及び閑散モードのいずれの状態においても、板形連結氷が移動を開始した後にアジテータ79が貯氷槽70内を攪拌する。具体的には、図12に示すように、スライドピン51の押し出し動作時において板形連結氷が移動を開始するとスライドピン51の負荷が小さくなってスライドピン51を移動させるモータ52の電流が低下する。そのため、第1設定では、例えば電流センサ106により検知したモータ52の電流が低下したときに、制御部100は、板形連結氷の移動を検知し、アジテータ79により貯氷槽70内を所定時間(本実施形態では16秒)攪拌する。また、繁忙モードにおいて第2設定に設定されている状態では、制御部100は、スライドピン51の押し出し動作時において押し出し開始時(又は徐氷の開始時)にアジテータ79が所定時間(本実施形態では16秒)攪拌する。一方、閑散モードにおいて第2設定に設定されている状態では、制御部100は、アジテータ79により攪拌を行わない。   The setting unit 104 is a switch that can be operated by the user, and can be switched by the user between the first setting and the second setting with less ice stored in the ice storage tank 70 than the first setting. . In the first setting, the control unit 100 controls the ice making unit 22 so that the ice storage tank 70 is always full in any of the busy mode and the sparse mode in the first setting. Then, in the state set to the first setting, the agitator 79 stirs the inside of the ice storage tank 70 after the plate-shaped connected ice starts to move in any state of the busy mode and the loose mode. Specifically, as shown in FIG. 12, when the plate-shaped connected ice starts moving during the pushing operation of the slide pin 51, the load on the slide pin 51 decreases and the current of the motor 52 moving the slide pin 51 decreases. Do. Therefore, in the first setting, for example, when the current of the motor 52 detected by the current sensor 106 decreases, the control unit 100 detects the movement of the plate-shaped connected ice, and the agitator 79 detects the inside of the ice storage tank 70 for a predetermined time ( In this embodiment, stirring is performed for 16 seconds. In addition, in a state where the second setting is set in the busy mode, the control unit 100 sets the agitator 79 for a predetermined time (the present embodiment) at the start of pushing (or at the start of slow ice) at the pushing operation of the slide pin 51. Let's stir for 16 seconds. On the other hand, in a state in which the second setting is set in the scattered mode, the control unit 100 does not perform agitation by the agitator 79.

次に、制御部100の処理を図9〜図11を参照しつつ説明する。
制御部100は、図9に示すように、タイマ101により時間を計測している(S1)。ユーザにより操作部99の操作ボタンが押されたことを検知すると(S2で「YES」)、制御部100は、モータ93を駆動し、操作ボタンの種類及び押した回数に応じた角度で氷定量器91Aを回動させ、定量室91の底部に形成した放出口92から氷を放出させるとともに、操作ボタンの種類及び回数により氷の放出量を算出する(S3)。また、制御部100は、氷の放出量に応じて貯氷槽70内の氷を放出機構90に搬送して定量室91内の氷を追加する。
Next, processing of the control unit 100 will be described with reference to FIGS. 9 to 11.
As shown in FIG. 9, the control unit 100 measures time by the timer 101 (S1). When detecting that the user has pressed the operation button of the operation unit 99 ("YES" in S2), the control unit 100 drives the motor 93 to determine the amount of ice at an angle according to the type of operation button and the number of times the button is pressed. The container 91A is rotated to discharge ice from the discharge port 92 formed at the bottom of the metering chamber 91, and the amount of ice discharge is calculated according to the type and number of operation buttons (S3). Further, the control unit 100 conveys the ice in the ice storage tank 70 to the discharge mechanism 90 according to the amount of ice discharge, and adds the ice in the metering chamber 91.

次に、タイマ101の経過時間及び放出量に基づいて、直近30分間における氷の放出量が閾値(600g)以上であるか否かを判断する(S4)。図8に示すように、直近30分間における氷の放出量が閾値(600g)以上である場合には(S4で「YES」)、制御部100は、繁忙モードとし、繁忙モードの製氷処理を行う(S5)。なお、直近30分間における氷の放出量の検出は、例えば常時(微小時間ごと)に検出することができる。   Next, based on the elapsed time and the release amount of the timer 101, it is determined whether the ice release amount in the last 30 minutes is equal to or more than the threshold value (600 g) (S4). As shown in FIG. 8, when the ice release amount in the last 30 minutes is equal to or more than the threshold value (600 g) ("YES" in S4), the control unit 100 sets the busy mode and performs the ice making process in the busy mode. (S5). The detection of the amount of ice released in the last 30 minutes can be detected, for example, constantly (every minute time).

繁忙モードの製氷処理では、図10に示すように、制御部100は、製氷機構20を動作させて製氷を行い(S11)、操作ボタンの操作に応じた閑散モードへの切り替えがなければ(S12で「NO」)、検知部41が満氷を検知するまで製氷し続ける(S13で「NO」,S11)。そして、操作ボタンの操作回数に応じて閑散モードに切り替えられると(S12で「YES」)、繁忙モードの製氷処理を終了する。   In the ice making process in the busy mode, as shown in FIG. 10, the control unit 100 operates the ice making mechanism 20 to perform ice making (S11), and if there is no switching to the scattered mode according to the operation of the operation button (S12) Then, ice making is continued until the detecting unit 41 detects full ice ("NO" in S13, S11). Then, when the mode is switched to the scattered mode according to the number of times of operation of the operation button ("YES" in S12), the ice making process in the busy mode is ended.

S4において、直近30分間における氷の放出量が閾値(600g)以上でない場合には(S4で「NO」)、検知部41が満氷を検知しているが否か判断し(S7)、検知部41が満氷を検知している場合には(S7で「YES」)、図8に示すように、制御部100は、閑散モードとし、閑散モードの製氷処理を行う(S8)。   In S4, when the release amount of ice in the last 30 minutes is not the threshold value (600 g) or more ("NO" in S4), it is judged whether the detection unit 41 detects full ice (S7), detection When the part 41 detects full ice (“YES” in S7), as shown in FIG. 8, the control part 100 sets the scattering mode and performs ice forming processing in the scattering mode (S8).

閑散モードの製氷処理では、図11に示すように、操作ボタンの操作に応じた繁忙モードへの切り替えがなければ(S21で「NO」)、満氷検知後、所定時間(8時間)経過するまで製氷が行われない(S22で「NO」)。そして、満氷検知後、所定時間(8時間)経過したと判断すると(S22で「YES」)、検知部41が満氷を検知するまで製氷機構20を動作させて製氷を行い(S23、S24で「NO」)、検知部41が満氷を検知すると(S24で「YES」)、繁忙モードへの切り替えがなければ(S21で「NO」)、満氷検知後、所定時間(8時間)経過するまで製氷が行われない(S22で「NO」)。一方、操作ボタンの操作回数に応じて繁忙モードに切り替えられると(S21で「YES」)、閑散モードの製氷処理を終了する。
なお、第1設定では、繁忙モードや閑散モードであるか否かに関わらずに常に満氷になるまで製氷し続けるため、閑散モードにおいても第1設定の場合には、繁忙モードにおける製氷動作と同様に検知部41が満氷を検知するまで製氷し続けることになる。一方、繁忙モードにおいて第2設定の場合には、検知部41が満氷を検知した後は製氷を一旦終了する。
In the ice making process in the low concentration mode, as shown in FIG. 11, if there is no switching to the busy mode according to the operation of the operation button (“NO” in S21), a predetermined time (8 hours) elapses after full ice detection. Ice making is not performed ("NO" in S22). When it is determined that a predetermined time (8 hours) has elapsed after full ice detection (S22: "YES"), the ice making mechanism 20 is operated to perform ice making until the detection unit 41 detects full ice (S23, S24 If the detection unit 41 detects full ice (“YES” in S24), and if there is no switch to the busy mode (“NO” in S21), a predetermined time (8 hours) after full ice detection Ice making is not performed until it passes ("NO" in S22). On the other hand, when the mode is switched to the busy mode according to the number of times of operation of the operation button ("YES" in S21), the ice making process in the low energy mode is ended.
In the first setting, since ice making is always continued until the ice is full regardless of whether it is the busy mode or the sparse mode, the ice making operation in the busy mode and the ice making operation in the busy mode are also performed in the first setting. Similarly, ice making continues until the detection unit 41 detects a full ice. On the other hand, in the case of the second setting in the busy mode, the ice making is temporarily ended after the detecting unit 41 detects the full ice.

本実施形態によれば、以下の作用、効果を奏する。
アイスディスペンサ10は、氷を製氷する製氷部22と、製氷部22で製氷された氷を貯える貯氷槽70と、貯氷槽70に貯えられた氷を放出する放出口92と、放出口92からの氷の放出をユーザが操作可能な操作部99と、製氷部22による製氷を制御する制御部100と、を備え、制御部100は、所定時間内における放出口92からの氷の放出量に応じて繁忙モードと閑散モードとを切り替えるモード切り替え手段102を有し、閑散モードでは、繁忙モードよりも貯氷槽70の貯氷量が少なくなるように製氷部22による製氷を制御する。
According to the present embodiment, the following actions and effects are achieved.
The ice dispenser 10 includes an ice making unit 22 for making ice, an ice storage tank 70 for storing ice made by the ice making unit 22, an outlet 92 for releasing the ice stored in the ice container 70, and an outlet 92 The control unit 100 includes an operation unit 99 that allows the user to control the release of ice and a control unit 100 that controls ice making by the ice making unit 22. The control unit 100 responds to the amount of ice released from the discharge port 92 within a predetermined time. The mode switching means 102 switches between the busy mode and the low energy mode, and in the low energy mode, the ice making by the ice making unit 22 is controlled so that the ice storage amount of the ice storage tank 70 becomes smaller than that in the busy mode.

本実施形態によれば、制御部100がユーザによる氷の需要に応じて繁忙モードと閑散モードとを切り替えることにより、繁忙期の氷の不足や閑散期の無駄な製氷を抑制することができる。また、制御部100は、所定時間における放出口92からの氷の放出量に基づいて閑散モードと繁忙モードとを切り替えればよいため、簡素な構成で繁忙期と閑散期との双方における貯氷量の過不足を抑制することが可能となる。   According to the present embodiment, when the control unit 100 switches between the busy mode and the sparse mode according to the demand for ice by the user, it is possible to suppress the shortage of ice in the busy period and the useless ice making in the rainy period. In addition, since the control unit 100 may switch between the low energy mode and the high energy mode based on the amount of ice released from the outlet 92 at a predetermined time, the storage capacity of the ice storage amount in both the high energy period and the low energy period is simple. It becomes possible to control excess and deficiency.

操作部99は、操作回数に応じた量の氷を放出口92から放出させるものであり、制御部100は、操作部99の操作回数に応じて閑散モードと繁忙モードとを切り替える。
このようにすれば、氷の放出量を操作部99の操作回数に応じて検知することが可能になるため、閑散モードと繁忙モードとの切り替えの処理を容易に行うことができる。
The operation unit 99 discharges ice from the discharge port 92 in an amount corresponding to the number of operations, and the control unit 100 switches between the scattered mode and the busy mode according to the number of operations of the operation unit 99.
In this way, since it is possible to detect the amount of released ice according to the number of times of operation of the operation unit 99, it is possible to easily perform processing of switching between the scattered mode and the busy mode.

また、貯氷槽70が満氷であることを検知する検知部41を備え、制御部100は、所定時間内における放出口92からの氷の放出量が閾値以下であり、かつ、検知部41が満氷であることを検知した際に、繁忙モードから閑散モードに切り替える。
このようにすれば、貯氷槽70が満氷となった後に閑散モードとなるため、閑散モードにおける氷の不足を抑制することができる。
In addition, the ice storage tank 70 includes a detection unit 41 that detects that the ice is full, and the control unit 100 determines that the amount of ice released from the discharge port 92 within a predetermined time is equal to or less than a threshold and the detection unit 41 When it is detected that the ice is full, the busy mode is switched to the loose mode.
In this way, since the ice storage tank 70 is full ice and then the scattering mode is set, it is possible to suppress the shortage of ice in the scattering mode.

また、流下した水が凍結することによりブロック形氷が板状に連結された形状の板形連結氷が製氷面24に付着し、貫通孔18が形成された製氷板23と、貫通孔18に挿通され、製氷板23から板形連結氷が離脱する方向に板形連結氷を押し出すスライドピン51(押し出し部)と、板形連結氷の移動を検知する電流センサ106(移動検知部)と、貯氷槽70に貯えられた氷を攪拌するように動作するアジテータ79と、ユーザにより第1設定と第1設定よりも貯氷槽70に貯氷される氷の少ない第2設定とを切り替え可能な設定手段104と、を備え、制御部100は、第1設定に設定されている状態では、スライドピン51の押し出し動作時において電流センサ106が板形連結氷の移動を検知した後にアジテータ79を動作させ、第2設定に設定されている状態では、スライドピン51の押し出し動作時において電流センサ106が板形連結氷の移動を検知する前にアジテータ79を動作させる。
このようにすれば、ユーザの設定により、アジテータ79が貯氷槽70に貯氷される氷を攪拌するタイミングを変えることができるため、貯氷槽70に貯氷される氷の量をユーザの設定に応じて調節することができる。また、第2設定の場合は板形連結氷が落下する前にアジテータ79の攪拌を済ませてなるべく板形連結氷を砕かないようにする。そうすることで満氷検知がされやすくなって貯氷量が減る。
In addition, plate-shaped connected ice having a shape in which block-shaped ice is connected in a plate-like shape adheres to the ice making surface 24 by freezing the flowed down water, and the ice making plate 23 in which the through hole 18 is formed; A slide pin 51 (pushing portion) which inserts and pushes out the plate-shaped connection ice in a direction in which the plate-shaped connection ice separates from the ice making plate 23, and a current sensor 106 (movement detection unit) which detects the movement of the plate-type connection ice; A setting means capable of switching between an agitator 79 operating to agitate the ice stored in the ice storage tank 70 and a second setting with less ice stored in the ice storage tank 70 by the user than the first setting and the first setting In the state where the control unit 100 is set to the first setting, the control unit 100 operates the agitator 79 after the current sensor 106 detects the movement of the plate-shaped connection ice during the pushing operation of the slide pin 51, In a state where 2 is set to the setting, the current sensor 106 during the extrusion operation of the slide pin 51 to operate the agitator 79 prior to detecting the movement of the plate-shaped connecting ice.
In this way, the timing at which the agitator 79 stirs the ice stored in the ice storage tank 70 can be changed according to the user's setting, so the amount of ice stored in the ice storage tank 70 according to the user's settings It can be adjusted. In the case of the second setting, agitation of the agitator 79 is completed before the plate-shaped connected ice drops so that the plate-shaped connected ice is not broken as much as possible. By doing so, full ice detection can be easily performed and the amount of stored ice is reduced.

また、第2設定に設定されている状態で繁忙モードとなると、制御部100は、電流センサ106が板形連結氷の移動を検知する前にアジテータ79を動作させ、第2設定に設定されている状態で閑散モードとなると、制御部100は、アジテータ79を動作させない。
このようにすれば、より一層、貯氷量の過不足を抑制することが可能となる。
When the busy mode is set in the second setting, the controller 100 operates the agitator 79 before the current sensor 106 detects the movement of the plate-shaped connected ice, and is set to the second setting. In the low energy mode, the controller 100 does not operate the agitator 79.
In this way, it is possible to further suppress excess or deficiency of the amount of stored ice.

<実施形態2>
次に、実施形態2について図13,図14を参照しつつ説明する。実施形態1では、制御部100は、直近30分間における氷の放出量が閾値(600g)以上でない場合には、検知部41が満氷を検知しているか否か判断し、満氷時に閑散モードの処理を行う構成としたが、実施形態2では、直近30分間における氷の放出量が閾値(600g)以上でない場合には、満氷か否かに関わらず、閑散モードの処理を行うものである。以下では、実施形態1と同一の構成については同一の符号を付して説明を省略する。
Second Embodiment
Next, Embodiment 2 will be described with reference to FIGS. 13 and 14. In the first embodiment, the control unit 100 determines whether or not the detecting unit 41 detects full ice when the amount of released ice in the last 30 minutes is not equal to or more than the threshold (600 g). In the second embodiment, if the amount of ice released in the last 30 minutes is not equal to or greater than the threshold (600 g), the processing in the scattered mode is performed regardless of whether the ice is full or not. is there. In the following, the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

制御部100は、図14に示すように、タイマ101により時間を計測している(S31)。ユーザにより操作部99の操作ボタン押されたことを検知すると(S32で「YES」)、操作ボタンの種類及び回数により氷の放出量を算出する(S33)。次に、タイマ101の経過時間及び放出量に基づいて、直近30分間における氷の放出量が閾値(600g)以上である場合には(S34で「YES」)、制御部100は、図13に示すように、繁忙モードとし、上記した繁忙モードの製氷処理を行う(S35)。   As shown in FIG. 14, the control unit 100 measures time by the timer 101 (S31). When it is detected that the user has pressed the operation button of the operation unit 99 ("YES" in S32), the amount of ice released is calculated based on the type and number of times of the operation button (S33). Next, based on the elapsed time and the release amount of the timer 101, when the ice release amount in the last 30 minutes is the threshold value (600 g) or more ("YES" in S34), the control unit 100 in FIG. As shown, the busy mode is selected, and the above-described busy mode ice making process is performed (S35).

S34において、直近30分間における氷の放出量が閾値(600g)以上でない場合には(S34で「NO」)、制御部100は、図13に示すように、閑散モードとし、上記した閑散モードの製氷処理を行う(S36)。   In S34, when the release amount of ice in the last 30 minutes is not the threshold value (600 g) or more ("NO" in S34), the control unit 100 sets the scattered mode as shown in FIG. An ice making process is performed (S36).
