JP 2011-121629 A

  In the beverage dispenser described above, a large wall-shaped ice piece is formed around the heat transfer cooling body. When such a large wall-shaped ice is formed, heat exchange between ice and cooling water may be insufficient with respect to heat exchange between the beverage pipe and cooling water. That is, at the time of continuous dispensing of beverages, a situation may occur in which the cooling water is not sufficiently cooled despite the formation of a large piece of ice. Therefore, when the heat exchange between the ice and the cooling water is insufficient, the beverage cannot be sufficiently cooled during continuous dispensing of the beverage, and the low-temperature beverage cannot be stably and continuously provided. Cause it to occur.

  Then, this invention makes it a subject to provide the drink server which can provide a low temperature drink stably and continuously.

  A beverage server according to the present invention includes a cooling liquid tank that contains a cooling liquid that cools a beverage, a beverage pipe that is disposed in the cooling liquid tank and through which the beverage passes, an agitating member that stirs the cooling liquid, and ice from the cooling liquid. An ice-making member that produces an ice, and the beverage tube is annular in plan view, at least a portion of the ice-making member is located inside the beverage tube in plan view, and the stirring member is an ice-making member It is located above or below.

  According to the beverage server of the present invention, since at least a part of the ice making member is disposed inside the beverage pipe that is annular in plan view, the cooling liquid located inside the beverage pipe is further cooled. It becomes possible. Therefore, it is possible to increase the efficiency of heat exchange between the ice and the cooling liquid inside the beverage pipe. Moreover, the stirring member which stirs a cooling fluid is provided above or below the ice making member located inside the beverage pipe. Therefore, it becomes possible to send out the cooling liquid sufficiently cooled by the ice made by the ice making member to the outside of the beverage pipe by the stirring member. Therefore, the cooling liquid located inside and outside the beverage pipe can be sufficiently cooled even during continuous dispensing of the beverage, and a low-temperature beverage can be provided stably and continuously. Furthermore, the space inside the cooling liquid tank located inside the beverage pipe and above or below the stirring member can be effectively utilized as a space for arranging the ice making member.

  The stirring member may be provided above the ice making member. In this case, since the ice making member is located below the stirring member, the cooling liquid moved downward by stirring of the cooling liquid by the stirring member is sufficiently cooled by the ice making member, and the cooling sufficiently cooled by the ice making member is performed. The liquid can be circulated around the beverage tube. Therefore, the beverage passing through the beverage pipe can be sufficiently cooled.

  Moreover, the ice produced | generated by the ice making member may be a cone shape provided with the top part inside the drink pipe. In this case, it is possible to disperse the direction in which the coolant flows at the top by flowing the coolant that is stirred by the stirring member and passes through the inside of the beverage pipe toward the top of the cone-shaped ice. Therefore, it is possible to cool the beverage passing through the beverage pipe more sufficiently by pouring the coolant evenly inside the coolant bath.

  The top of the ice may be disposed in the vicinity of the stirring member. In this case, since the cooling liquid stirred by the stirring member is poured toward the top located in the vicinity of the stirring member, dispersion of the cooling liquid at the top can be promoted. Accordingly, it becomes possible to flow the cooling liquid more evenly.

  Further, the inside of the beverage pipe and the outside of the ice generated by the ice making member are close to each other, and a flow path through which the cooling liquid passes between the inside of the beverage pipe and the outside of the ice may be formed. In this case, since the inside of the beverage pipe is close to the ice, it is possible to promote the cooling of the beverage. In addition, since a flow path through which the cooling liquid passes is formed between the inside of the beverage pipe and the outside of the ice, the cooling liquid in the cooling liquid tank is poured by flowing the cooling liquid cooled with ice into this flow path. Sufficient cooling can be continued.

  According to the present invention, a low-temperature beverage can be provided stably and continuously.

  Hereinafter, embodiments of a beverage server and a control method thereof according to the present invention will be described in detail with reference to the drawings. In all drawings, the same or corresponding parts are denoted by the same reference numerals.

(First embodiment)
FIG. 1 shows an overall configuration of a beverage providing apparatus 1 including a beverage server (server 10) according to the present embodiment. The beverage providing device 1 is a device provided in a restaurant, for example, and is a device that pours beer from the currant 9 in accordance with a customer order or the like. First, the whole structure of the drink provision apparatus 1 is demonstrated. The beverage providing device 1 includes a carbon dioxide cylinder 2, a pressure reducing valve 3, a carbon dioxide hose 4, a beer barrel 5, a head 6, a beer hose 7, and a server 10 in addition to the currant 9.

  The carbon dioxide cylinder 2 is a substantially cylindrical container filled with carbon dioxide at a high pressure. The carbon dioxide cylinder 2 has a function of pushing out the beer liquid inside the beer barrel 5 to the server 10 and also has a function of keeping the amount of carbon dioxide contained in the beer liquid inside the beer barrel 5 at an appropriate amount. Inside the carbon dioxide cylinder 2, the carbon dioxide is filled in a liquid state, for example, at a pressure of about 6 to 8 MPa.

  The carbon dioxide gas cylinder 2 includes a remaining amount indicator 2 a that displays the amount of carbon dioxide gas inside the carbon dioxide gas cylinder 2. As the remaining amount indicator 2a, for example, a needle-shaped one can be used. In this case, when the needle is pointing upward, the amount of carbon dioxide in the carbon dioxide cylinder 2 is relatively large, When the needle is pointing downward, it indicates that the amount of carbon dioxide in the carbon dioxide cylinder 2 has decreased. Thus, the carbon dioxide gas cylinder 2 is provided with the remaining amount indicator 2a, so that the amount of carbon dioxide gas in the carbon dioxide gas cylinder 2 can be visually recognized. The carbon dioxide gas cylinder 2 is provided with an opening / closing handle (not shown) that can be rotated by a user at the top of the carbon dioxide gas cylinder 2, and the flow path of the carbon dioxide gas from the carbon dioxide gas cylinder 2 to the pressure reducing valve 3 by the rotation of the opening / closing handle. Can be opened and closed.

  The pressure reducing valve 3 is a device for adjusting the pressure (hereinafter referred to as gas pressure) due to carbon dioxide applied to the beer liquid inside the beer barrel 5. The pressure reducing valve 3 includes a residual pressure indicator 3 a that displays the residual pressure of the carbon dioxide gas in the carbon dioxide cylinder 2 and a rotary operation unit 3 b for adjusting the gas pressure. For example, the user can increase the gas pressure by rotating the operation unit 3b in the clockwise direction and can decrease the gas pressure by rotating the operation unit 3b in the counterclockwise direction. Here, the amount of carbon dioxide dissolved in the liquid decreases as the temperature of the liquid increases, and increases as the temperature of the liquid decreases. Therefore, by adjusting the gas pressure to an appropriate value with the pressure reducing valve 3 in accordance with the temperature of the beer liquid inside the beer barrel 5, gas separation from which the carbon dioxide gas escapes from the beer liquid at a high temperature, or the beer liquid is a carbon dioxide gas at a low temperature It is possible to prevent oversaturation that absorbs excessively.

  The beer barrel 5 is a container filled with beer liquid. Since the inside of the beer barrel 5 is hermetically sealed, various germs and the like are prevented from entering the inside of the beer barrel 5. Further, for example, a card-like liquid temperature detection unit 5a can be attached to the surface of the beer barrel 5, and the temperature of the beer in the beer barrel 5 can be detected by the liquid temperature detection unit 5a. it can. In addition to the temperature of the beer in the beer barrel 5, the liquid temperature detector 5a displays the optimum value of the gas pressure corresponding to the detected temperature of the beer.

  Therefore, the user can adjust the gas pressure in the beer barrel 5 to an optimum value by operating the operation unit 3b of the pressure reducing valve 3 and setting the gas pressure to the value displayed on the liquid temperature detection unit 5a. It has become. The beer barrel 5 includes a tube 5b through which beer flows and a base (also referred to as a fitting valve) 5c. The tube 5b of the beer barrel 5 extends vertically inside the beer barrel 5, and the cap 5c is provided at the upper end of the tube 5b.

  The head 6 has a function of sending the carbon dioxide in the carbon dioxide cylinder 2 into the beer barrel 5 via the pressure reducing valve 3 and the carbon dioxide hose 4 and sending out the beer liquid in the beer barrel 5 to the server 10. The head 6 has an operation handle 6a capable of opening and closing a flow path of carbon dioxide gas and beer liquid by moving up and down, a gas joint 6b connected to the carbon dioxide hose 4, and a beer joint 6c connected to the beer hose 7. It has.

  The lower part of the head 6 is connected to the base 5c of the beer barrel 5, and the flow path of the carbon dioxide hose 4 and the beer hose 7 is lowered by lowering the operation handle 6a of the head 6 with the lower part of the head 6 connected to the base 5c. Is opened, and the flow path of the carbon dioxide hose 4 and the beer hose 7 is closed by raising the operation handle 6a of the head 6. The gas joint 6b and the beer joint 6c are detachable from the main body 6d extending vertically at the center of the head 6, and the gas joint 6b, the beer joint 6c and the main body 6d can be disassembled. Thus, the head 6 can be easily cleaned.

  The server 10 is connected to the head 6 via the beer hose 7 and has a function of cooling the beer liquid sent from the beer barrel 5 via the head 6 and the beer hose 7. The server 10 is a so-called electric cooling type instantaneous cooling type server. The server 10 has a rectangular parallelepiped shape, and the beer hose 7 enters the upper end of the side surface of the server 10. The server 10 cools the beer liquid supplied from the beer hose 7, and the beer liquid cooled by the server 10 is poured out from the currant 9 when the currant 9 is pulled forward, for example.

  As shown in FIGS. 1 and 2, the server 10 is connected to a rectangular parallelepiped water tank (cooling liquid tank) 11 that stores cooling water (cooling liquid) W and a beer hose 7. The beer coil (beverage pipe) 12 formed in a spiral shape and the refrigeration cycle apparatus 15 for cooling the cooling water W are provided. The beer coil 12 extends downward from the connection portion with the beer hose 7, extends spirally around the axis L from the lower end thereof, and extends to the currant 9 at a portion drawn upward from the cooling water W at the upper end portion extending spirally. It is connected. The axis L is, for example, a reference line extending in the vertical direction at the central portion of the water tank 11 in plan view. The beer coil 12 is not limited to a spiral shape, and may be an annular shape in a plan view. For example, the beer coil 12 may be a square annular shape extending upward. Since the beer coil 12 is thus spiraled to ensure a long flow path for the beer liquid in the cooling water W, the beer liquid in the beer coil 12 is more instantaneously preferable in the server 10. To be cooled.

  As shown in FIGS. 2 to 4, the refrigeration cycle apparatus 15 includes a refrigerant pipe 16 that spirally extends so as to surround the beer coil 12 outside the beer coil 12 in the cooling water W. The refrigeration cycle apparatus 15 includes the refrigerant pipe 16, the compressor 17, the condenser 18, the fan 19, the dehydrator 20, and the capillary tube 21, and the refrigeration cycle apparatus 15 includes the refrigerant pipe 16, the compressor 17, A refrigeration cycle in which the condenser 18, the dehydrator 20 and the capillary tube 21 are sequentially connected is configured.

  The compressor 17 is connected to the lower end of the refrigerant pipe 16, and the refrigerant flows into the compressor 17 from the refrigerant pipe 16. The compressor 17 compresses the refrigerant to generate a high-temperature refrigerant gas of, for example, 70 ° C., and the condenser 18 releases heat from the high-temperature refrigerant gas, so that the condenser 18 generates a high-temperature refrigerant liquid of, for example, 40 ° C. Generate. The fan 19 has a function of sending air to the condenser 18 and efficiently exchanging heat in the condenser 18. The high-temperature refrigerant liquid generated by the condenser 18 is sent to the capillary tube 21 via the dehydrator 20. The capillary tube 21 is connected to the upper end of the refrigerant pipe 16, performs a pressure reduction and a flow rate control on the high-temperature refrigerant liquid sent via the dehydrator 20 to generate a liquid refrigerant at −8 ° C., for example, This liquid refrigerant is supplied to the refrigerant pipe 16.

  The server 10 includes a propeller 22 and a motor 23. The propeller 22 agitates the cooling water W in the water tank 11 and forms a flow in the cooling water W, thereby exchanging heat between the cooling water W and the beer coil 12 and exchanging heat between the cooling water W and the refrigerant pipe 16. Promote. The motor 23 is disposed above the beer coil 12, and the shaft 22 a of the propeller 22 attached to the motor 23 enters the inside of the beer coil 12. Therefore, the cooling water W located inside the beer coil 12 moves downward by the rotation of the propeller 22, and forms a flow that moves to the outside of the water tank 11 at the bottom surface 11 a of the water tank 11.

  Further, as described above, since the liquid refrigerant is supplied from the capillary tube 21 to the refrigerant pipe 16, the cooling water W located around the refrigerant pipe 16 is cooled by the liquid refrigerant, and ice K1 is formed around the refrigerant pipe 16. Is generated. It takes several hours (for example, 7 or 8 hours) from the time when the server 10 is turned on with the cooling water W in the water tank 11 until the ice K1 is generated. Thus, for example, if the server 10 is turned on at the end of business hours at night in a restaurant, ice is formed around the refrigerant pipe 16 at night, and ice K1 is generated by the start of business on the next day. State.

  Here, as shown in FIG. 5A, a flow path of the cooling water W is formed between the ice K <b> 2 (described later in detail) located below the propeller 22 and the beer coil 12. Therefore, the cooling water W moved downward by the rotation of the propeller 22 flows toward the ice K2, and moves toward the bottom surface 11a of the water tank 11 through the side of the ice K2. Moreover, since the flow path of the cooling water W is formed between the beer coil 12 and the ice K1 by the refrigerant pipe 16, the cooling water W moving toward the bottom surface 11a moves to the outside of the water tank 11 at the bottom surface 11a. , Move upward between the ice K1 and the beer coil 12. Thus, the cooling water W moving upward inside the ice K1 is poured into the beer coil 12 side above the ice K1.

  As shown in FIGS. 5B and 6, the server 10 includes a control unit 30 that controls the thickness of the ice K <b> 1 formed in the refrigerant pipe 16. It has a sensor 31 that detects the thickness. The sensor 31 is provided so as to protrude from the inner surface 11 b of the water tank 11 to the inside of the water tank 11. The sensor 31 includes two rod-shaped electrodes 32 and 33, and the lengths of these electrodes 32 and 33 are different from each other. The sensor 31 detects the thickness of the ice K1 by detecting conduction or non-conduction between the electrode 32 and the electrode 33. Specifically, when the tip 32a of the electrode 32 and the tip 33a of the electrode 33 are in contact with the cooling water W and are conductive, it is detected that the thickness of the ice K1 is thin, and the tip 32a of the electrode 32 becomes the ice K1. When the tip 32a is buried and the tip 33a is non-conductive, it is detected that the ice K1 is thick.

  When the sensor 31 detects that the ice K1 is thin, the control unit 30 supplies the liquid refrigerant to the refrigerant pipe 16 by the refrigeration cycle device 15 and cools the refrigerant pipe 16, thereby thickening the ice K1. To control. On the other hand, when the sensor 31 detects that the ice K1 is thick, the control unit 30 stops the supply of the liquid refrigerant to the refrigerant pipe 16 by the refrigeration cycle device 15 so that the ice K1 does not become thicker than this. To control. In the sensor 31, the thickness of ice generated around the refrigerant pipe 16 can be controlled by adjusting the positions of the two electrodes 32 and 33.

  As shown in FIG. 7A, the server 10 includes a spiral refrigerant pipe (ice-making member) 50 surrounded by the beer coil 12 inside the beer coil 12 in the cooling water W. The refrigerant pipe 50 has an annular shape in plan view, and a part of the upper side of the refrigerant pipe 50 enters the inside of the beer coil 12. The refrigerant pipe 50 may constitute the same refrigeration cycle apparatus 15 as the refrigerant pipe 16, or may constitute a refrigeration cycle apparatus different from the refrigerant pipe 16.

  The refrigerant pipe 50 is supplied with the same liquid refrigerant as the refrigerant pipe 16. Therefore, the cooling water W positioned around the refrigerant pipe 50 is cooled by the liquid refrigerant, and cylindrical ice K2 is generated around the refrigerant pipe 50. In addition, since the propeller 22 is provided above the refrigerant pipe 50, the cooling water W that moves downward by the rotation of the propeller 22 flows toward the ice K <b> 2 generated by the refrigerant pipe 50. The cooling water W flowing toward the ice K2 moves to the bottom surface 11a of the water tank 11 through the side of the ice K2.

  As described above, in the server 10, a part (upper side) of the refrigerant pipe 50 is disposed inside the beer coil 12 that is annular in a plan view, so that the cooling water W located inside the beer coil 12. Can be further cooled. Therefore, the efficiency of heat exchange between the ice K2 and the cooling water W inside the beer coil 12 can be increased.

  A propeller 22 for stirring the cooling water W is provided above the refrigerant pipe 50 located inside the beer coil 12. Therefore, it is possible to send out the cooling water W sufficiently cooled by the refrigerant pipe 50 to the outside of the beer coil 12 by the propeller 22. Therefore, the cooling water W located inside and outside the beer coil 12 can be sufficiently cooled even when beer is continuously poured out, and low-temperature beer can be provided stably and continuously. Furthermore, the space in the water tank 11 located inside the beer coil 12 and below the propeller 22 can be effectively used as a space for arranging the refrigerant pipe 50.

  The propeller 22 is located above the refrigerant pipe 50 located inside the beer coil 12, and the refrigerant pipe 50 is located below the propeller 22. Therefore, the cooling water W moved downward by the stirring of the cooling water W by the propeller 22 is sufficiently cooled by the refrigerant pipe 50, and the cooling water W sufficiently cooled by the refrigerant pipe 50 is circulated around the beer coil 12. Is possible. Therefore, the beer passing through the beer coil 12 can be sufficiently cooled.

  In the server 10 of the first embodiment, the inside of the beer coil 12 and the outside of the ice K2 generated by the refrigerant pipe 50 are close to each other, and between the inside of the beer coil 12 and the outside of the ice K2. It is preferable that a flow path through which the cooling water W passes is formed. Here, the fact that the inside of the beer coil 12 and the outside of the ice K2 are close to each other means that a gap is formed between the ice K2 in the plan view and the beer coil 12 in the plan view so that a water flow is formed. At this time, the flow path between the inner side of the beer coil 12 and the outer side of the ice K2 is narrowed. In this case, since the inside of the beer coil 12 is close to the ice K2, cooling of the beer can be promoted. Further, a flow path is formed through which the cooling water W passes between the inside of the beer coil 12 and the outside of the ice K2 in a direction from the outside of the beer coil 12 to the inside of the ice K1. Therefore, the cooling water W cooled by the ice K2 is poured into the flow path, so that the cooling water W in the water tank 11 can be sufficiently cooled.

(Second Embodiment)
As shown in FIG. 7B, the beverage server of the second embodiment includes a refrigerant pipe 55 that is annular in plan view. A part (lower part) of the refrigerant pipe 55 enters the inside of the beer coil 12. The refrigerant pipe 55 may constitute the same refrigeration cycle apparatus 15 as the refrigerant pipe 16, or may constitute a refrigeration cycle apparatus different from the refrigerant pipe 16. The beverage server according to the second embodiment includes a motor 53 disposed below the beer coil 12 and a propeller 52 including a shaft 52a that extends upward from the motor 53 and enters the beer coil 12 from below. The cooling water W located inside the beer coil 12 moves upward by the rotation of the propeller 52.

  In addition, since the columnar ice K5 is generated around the refrigerant pipe 55 that has an annular shape in plan view, a flow path of the cooling water W is formed between the ice K5 and the beer coil 12. Therefore, the cooling water W moved upward by the rotation of the propeller 52 flows toward the ice K5 and moves toward the upper surface of the water tank 11 through the side of the ice K5. The cooling water W moving toward the upper surface of the aquarium moves toward the outside of the aquarium 11 on the upper surface of the aquarium 11, and moves downward between the ice K1 and the beer coil 12. And the cooling water W which moves below inside the ice K1 is poured into the beer coil 12 side below the ice K1.

  Thus, the drink server of 2nd Embodiment is located inside the beer coil 12 by arrange | positioning a part of refrigerant pipe 55 inside the beer coil 12 similarly to the server 10 of 1st Embodiment. It becomes possible to further cool the cooling water W. The propeller 52 provided below the refrigerant pipe 55 can also feed the cooling water W sufficiently cooled by the ice K5 of the refrigerant pipe 55 to the outside of the beer coil 12. Therefore, as in the first embodiment, a low-temperature beer can be provided stably and continuously, and the space in the water tank 11 located inside the beer coil 12 and above the propeller 52 can be used as a refrigerant. It can be effectively used as a space for arranging the pipe 55. In the beverage server of the second embodiment, the ice K5 generated around the refrigerant pipe 55 has a cylindrical shape. However, the shape and size of the ice K5 can be changed by changing the shape and size of the refrigerant pipe 55. Can be changed as appropriate.

(Third embodiment)
As shown in FIG. 8A, the beverage server according to the third embodiment includes a refrigerant pipe 60 that is spiral in the vicinity of the axis L. The refrigerant pipe 60 has an annular shape in plan view, and a part of the upper side of the refrigerant pipe 60 enters the inside of the beer coil 12. The refrigerant pipe 60 may constitute the same refrigeration cycle apparatus 15 as the refrigerant pipe 16, or may constitute a refrigeration cycle apparatus different from the refrigerant pipe 16. The beverage server of the third embodiment includes an ice forming member 61 that controls the shape of the ice K3 formed around the refrigerant pipe 60. The ice forming member 61 is made of a material having a high thermal conductivity such as metal, and is fixed to the refrigerant pipe 60. The ice forming member 61 has an annular shape in plan view surrounding the refrigerant pipe 60, and the outer diameter of the ice forming member 61 increases toward the lower side. When the liquid refrigerant is supplied to the refrigerant pipe 60, the cooling water W located around the refrigerant pipe 60 and the ice forming member 61 is cooled, and ice K3 is generated around the refrigerant pipe 60 and the ice forming member 61. The ice K3 has a conical shape with a top portion T inside the beer coil 12.

  As described above, in the beverage server according to the third embodiment, since the ice K3 generated by the refrigerant pipe 60 has a conical shape with the top T inside the beer coil 12, the beer coil is stirred by the propeller 22. The cooling water W passing through the inside 12 is poured toward the top T of the conical ice K3. Therefore, since it becomes possible to disperse | distribute the direction in which the cooling water W flows in the top part T, the cooling water W can be poured evenly in the water tank 11, and the beer which passes the beer coil 12 can be cooled more fully. It becomes. In the third embodiment, the ice K3 has a conical shape, but may have a different pyramid shape such as a pyramid shape. In this case, the same effect as described above can be obtained.

  In the beverage server according to the third embodiment, the top T of the ice K3 is preferably disposed in the vicinity of the propeller 22. Here, the top portion T of the ice K3 being disposed in the vicinity of the propeller 22 indicates a state in which the top portion T is not in contact with the propeller 22 and the top portion T is located directly below the propeller 22. By disposing the top portion T of the ice K3 in the vicinity of the propeller 22 in this way, the cooling water W stirred by the propeller 22 is poured toward the top portion T located in the vicinity of the propeller 22. Accordingly, the dispersion of the cooling water W at the top T can be promoted, and the cooling water W can be poured evenly.

  In addition, it is preferable that ice is arrange | positioned in the vicinity of the propeller 22 also in the case of the ice where the surface facing the propeller 22 is flat like the columnar ice K2. However, it is more preferable that the distance between the propeller 22 and the ice is such that the cooling water W moved downward by the propeller 22 passes through the side of the ice. Similarly to the above, the ice K5 of the second embodiment is also preferably disposed in the vicinity of the propeller 52.

(Fourth embodiment)
As shown in FIG. 8 (b), the beverage server of the fourth embodiment includes a refrigerant pipe 70 connected to the refrigerant pipe 16 of the first embodiment and a space S below the water tank 71. The water tank 71 contains the cooling water W like the water tank 11 of 1st Embodiment shown by Fig.8 (a). The aquarium 71 is different from the aquarium 11 in that a bottom plate 72 is provided at the lower portion and a space S is formed below the bottom plate 72.

  The lower end of the refrigerant pipe 16 enters the bottom plate 72 and is curved inward in the space S below the bottom plate 72. The refrigerant pipe 70 has a spiral shape protruding upward from the bottom plate 72 inside the beer coil 12 in plan view. In such a beverage server of the fourth embodiment, ice K4 similar to the ice K2 of the first embodiment is formed below the propeller 22 and inside the beer coil 12. Therefore, the same effect as the server 10 of 1st Embodiment is acquired.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to each embodiment mentioned above, A various form is employable.

  For example, in the said embodiment, although the cooling water W was accommodated in the water tank 11, things other than water (for example, antifreeze etc.) can also be used as a cooling liquid which cools a drink. For example, instead of the water tank 11 that stores the cooling water W, a cooling liquid tank that stores the antifreeze liquid may be used.

Furthermore, in the said embodiment, although the refrigerant pipe was illustrated as an ice-making member which produces | generates ice, it is also possible to use ice-making members other than a refrigerant pipe. For example, instead of the refrigerant pipe 50, a Peltier element that generates ice from the cooling water W can be used as the ice making member.

  In the above embodiment, the thickness of the ice K1 is detected by the sensor 31 having the two electrodes 32 and 33. However, a sensor for detecting the thickness of the ice K2, the ice K3, or the ice K4 may be provided separately. . It is also possible to use a sensor other than the sensor 31 described above. For example, instead of the sensor 31, a temperature sensor that detects the temperature around the refrigerant pipe 16 may be used.
