Description

  The present invention relates to an auger type ice making machine that generates ice pieces continuously by scraping ice generated on the inner wall of a cooling cylinder with an auger, transferring it upwards and compressing it, and storing it in an ice storage. In particular, the present invention relates to a configuration of an agitator that pushes generated ice pieces to a chute that communicates an ice making side and an ice storage.

  Conventionally, this type of auger type ice making machine inserts an auger rotatably into a cooling cylinder having a passage (cooler) through which refrigerant passes, and water for making ice from a water supply pipe into the cooling cylinder. In addition to feeding, the auger is rotationally driven by a motor, and the ice generated on the inner wall of the cooling cylinder is scraped and transferred upward and compressed to continuously generate ice pieces ( For example, see Patent Document 1.)

  In the related art, the generated ice pieces are led to an ice storage provided above the cooling cylinder, and provided with a shutter that can be opened and closed on a side surface of the ice storage, and a stirrer provided in the ice storage is provided. By rotating, a predetermined amount of ice pieces can be taken out from the opened shutter.

  In the above configuration, since the ice storage amount is limited, there is an ice storage device provided on the side of the auger type ice making machine (ice making unit) for the purpose of expanding the ice storage amount. In this case, as shown in FIG. 14, an upper chamber 201 is formed above the cooling cylinder, and a chute 203 that communicates between the upper chamber 201 and the ice storage 202 is transferred into the upper chamber 201. And an agitator 204 that pushes the coming ice piece I onto the chute 203. The agitator 204 includes a rotary shaft 205 connected to the upper end of the auger and two extrusion blades 206 and 206 attached to the side surface of the rotary shaft 205. The extrusion blades 206, 206 rotate together with the auger at a predetermined low speed to push out the ice pieces I transferred into the upper chamber 201 onto the chute 203.

  The ice pieces I pushed out to the chute 203 fall into the ice storage 202 from the end of the chute 203 opened to the ice storage 202 side by the ice pieces I continuously pushed out, and are stored in the ice storage 202. Here, an ice full detection switch 207 is provided near the exit of the chute 203 in the ice storage 202. Ice pieces are accumulated in the ice storage 202, and the ice piece I at the top is the ice detection switch 207. When the full ice is detected continuously for a predetermined time, the operation of the ice making unit is stopped. In the prior art in FIG. 14, when the detection plate 207A provided in the full ice detection switch 207 has the opening in FIG. 14, the full ice detection switch 207 is turned OFF, and the opening in FIG. Is set to ON.

Further, a limit sensor 208 is provided on the upper surface of the upper chamber 201 so as to be positioned above the agitator 204. This limit sensor 208 is a safety device that detects ice pieces I that are not smoothly led out to the chute 203 but clogged up to the upper part of the upper chamber 201 above the agitator 204 and stops the operation of the ice making unit.

  In the structure described above, the basic operation of the ice making unit 3 will be described. In the first initial cleaning process, the low water level switch 59 is ON, and the microcomputer of the control board K opens the water supply valve 77 and the drain valve 76 to supply water into the cooling cylinder 90 and drain the water.

  In the initial cleaning process and the ice making process, the microcomputer executes a draining operation in which the drain valve 76 is opened for 30 seconds (timed drainage time) every hour (timed drainage interval) in an initial setting state. Thereby, the ice making water in the cooling cylinder 90 is discarded, and the cooling cylinder 90 is cleaned. Accordingly, the drain valve 76 is opened for 30 seconds also in this initial cleaning process.

  Further, the water supply valve 77 is kept open even after the drain valve 76 is closed, and water is supplied until the full water level switch 58 is turned on in this initial cleaning process. The amount of water supplied from the water supply pipe is set so that the amount of water is larger than the amount of water discharged from the drain pipe. Therefore, if the water supply valve 77 is opened even if the drain valve 76 is open, a predetermined time elapses. Thereafter, the low water level switch 59 is turned OFF. Simultaneously with the start of the initial cleaning process, the auger motor 28 is energized and the auger 91 is driven to rotate.

  When the full water level switch 58 is turned on, the ice making process is subsequently started, the water supply valve 77 is turned off, and the compressor 40 (compressor motor 61) and the fan motor 68 are turned on to make ice.

  In this ice making process, ice formed on the inner wall of the cooling cylinder 90 is scraped and transferred upward by the auger 91 and compressed in the ice compression path of the upper bearing 94 to continuously generate ice pieces I. To do. The generated ice pieces I are transferred into the upper chamber 96 from the upper end of the cooling cylinder 90. The ice pieces I transferred into the upper chamber 96 are rotated by the rotating shaft 100 of the agitator 95 in synchronism with the auger 91, so that the extrusion blades 101, 101 provided on the rotating shaft 100 rotate. As a result, it is pushed out to the chute 35 as shown in the partially enlarged view of FIG.

  At this time, since the extrusion blade 101 of the agitator 95 is provided with the roof portion 105, it is possible to prevent the inconvenience that the ice pieces I transferred from the cooling cylinder 90 escape above the agitator 95. Become. In addition, the lower surface 105A of the roof portion 105 can push out the ice piece I while pressing the ice piece I obliquely from above with the surface that pushes out the ice piece I of the main body 103, that is, the surface facing the rotation direction. The pushing force of the ice piece I by the agitator 95 can be increased.

  Further, the extrusion blade 101 is provided with the main body 103 that exerts the pushing force of the ice piece I extending vertically by a predetermined dimension, so that the ice piece accumulated in the chute 35 by the rotation of the extrusion blade 101. It becomes possible to extrude I reliably.

  Thereby, the ice pieces I accumulated in the chute 35 fall from the ice piece outlet 35A of the chute 35 by the pushing force of the extrusion blade 101, and are led out and stored in the ice storage 8. Here, the ice pieces I accumulated in the ice storage 8 are accumulated in a mountain shape with the vicinity of the ice piece outlet 35A of the chute 35 as a vertex due to the natural fall from the ice piece outlet 35A (in FIG. 13). Dashed line S1). The ice piece I at the apex pushes up the detection plate 36A of the full ice sensor 36 to a predetermined opening degree.

  In this state, in this embodiment, since the roof portion 105 is provided on the extrusion blade 101 of the agitator 95, the ice piece I transferred from the upper bearing 94 by the roof portion 105 escapes upward from the agitator 95. It is possible to avoid the inconvenience. Therefore, since the force pushed out to the chute 35 increases, the peak of the ice piece I before the predetermined time, in this embodiment, 30 seconds elapses after the detection plate 36A of the full ice sensor 36 is set to the predetermined opening degree. Can be broken (broken line S2 in FIG. 13).

  As a result, the full ice sensor 36 once detects full ice, but the top of the mountain is destroyed by the ice piece I pushed out from the agitator 95 before the predetermined time elapses. 36 is OFF. Therefore, the ice making unit 3 continues ice making without stopping.

  Thereafter, by the pushing force of the extrusion blade 101, the ice piece I further falls from the ice piece outlet 35A of the chute 35 and is deposited on the mountain of the ice piece I that has been collapsed last time. It will be accumulated in a mountain shape. Even in such a case, the ice piece I at the apex pushes up the detection plate 36A of the full ice sensor 36 to a predetermined opening degree, but the detection plate 36A of the full ice sensor 36 has a predetermined opening degree as described above. Then, before the elapse of a predetermined time, in this example, 30 seconds, the mountain of the ice piece I can be broken (broken line S3 in FIG. 13). In this case as well, the full ice sensor 36 once detects full ice, but the top of the mountain is broken by the ice piece I pushed out from the agitator 95 before the predetermined time elapses. The sensor 36 is turned off. Therefore, the ice making unit 3 continues ice making without stopping.

  By repeating the above operation, the ice pieces I are accumulated in the ice storage 8 at a high level (solid line S4 in FIG. 13), and when the ice pieces I are filled to the full ice storage 8, the full ice sensor 36 continues. In this embodiment, the microcomputer of the control board K turns off the compressor 40 and the fan motor 68, and after 90 seconds, the auger motor 28 is detected. To turn off the ice making process (ice making operation).

  In the ice making process as described above, when the ice making water in the cistern 42 is exhausted, the low water level switch 59 is turned on, the water supply valve 77 is opened by the microcomputer of the control board K, and water supply is started, and the full water level switch 58 is turned on. Then, the water supply valve 77 is closed.

  As described above, according to the present invention, by increasing the pushing force of the ice piece I by the agitator 95, the ice piece I is smoothly pushed out from the upper chamber 96 to the chute 35, and as a result, dead occurs in the ice storage 8. Space can be reduced.

  Further, in this embodiment, the roof portion 105 is integrally formed on the upper portion of the extrusion blade 101, so that the number of parts can be reduced and the increase in cost can be suppressed to the minimum. Become. Further, since the roof portion 105 is configured to be inclined outward, even when the ice piece I is placed on the roof portion 105, the roof portion 105 can be quickly dropped by the inclination. In addition, it is possible to prevent or suppress the disadvantage that ice pieces are clogged in the upper chamber 96 above the agitator 95. Therefore, the inconvenience that the ice piece I is clogged in the upper chamber 96 above the agitator 95 and the limit switch 50 is operated to cause the ice making unit 3 to stop urgently is avoided.

  In particular, in the present embodiment, the roof portion 105 is configured to be inclined at a low angle toward the space formed between the extrusion blades 101 and 101. Therefore, the ice piece I that has fallen from the upper surface 105B of the roof portion 105 is formed. Can be pushed out to the chute 35 by the pushing blade 101, and the ice piece I can be pushed out smoothly.

  After the ice making process as described above is completed, the ice storage process is then started. After that, the ice piece I is taken out from the ice storage 8 and decreases, and when the full ice sensor 36 no longer detects full ice, the full ice sensor is detected. After 150 seconds from the detection of full ice in 36, the microcomputer of the control board K determines that ice making has started, turns on the auger motor 28 and opens the drain valve 76. Here, since the water is once drained, the low water level switch 59 is turned ON. At the same time when the low water level switch 59 is turned on, the microcomputer of the control board K opens the water supply valve 77 and continues water supply until the full water level switch 58 detects full water.

  When the full water level switch 58 is turned on, the process proceeds to the ice making process again, and the compressor 40 (compressor motor 61) and the fan motor 68 are turned on to resume ice making. As a result, an amount of ice pieces I corresponding to the capacity of the ice storage 8 is always stored in the ice storage 8.

  With the above configuration, the operation of the beverage dispenser 1 will be described. The control device 45 puts the syrup, carbonated water, and dilution water into a supply standby state. That is, the control device 45 opens the flow rate regulator 13 of the syrup supply pipe 14 filled with each syrup, and causes the syrup to flow into the beverage cooling flow path 9 </ b> A of the cold plate 9. Here, since the ice made in advance by the ice making unit 3 is always stored in a full ice state in the ice storage 8, the cold plate 9 is cooled to a predetermined temperature by the cold heat of the ice. Therefore, the syrup in the beverage cooling channel 9A is cooled to a predetermined temperature (a temperature at which it does not freeze, for example, 0 ° C.). The syrup that has flowed out of the beverage cooling channel 9A reaches the beverage supply valve 5 that is closed via the beverage supply pipe 25, and enters a supply standby state.

  Further, the control device 45 causes the dilution water to flow from the carbonator 20 into the dilution water cooling passage 9C of the cold plate 9 via the dilution water supply pipe 24 and cool it to a predetermined temperature in the same manner as the syrup. And the dilution water which flowed out from the dilution water cooling flow path 9C arrives at the drink supply valve 5 closed via the dilution water supply piping 27, and will be in a supply standby state.

  The control device 45 causes the carbonated water generated in the carbonator 20 to flow into the carbonated water cooling channel 9B of the cold plate 9 via the carbonated water supply pipe 23 and cools it to a predetermined temperature in the same manner as the syrup. Then, the carbonated water flowing out from the carbonated water cooling channel 9 </ b> B reaches the beverage supply valve 5 closed via the carbonated water supply pipe 26.

  Here, in the vicinity of the inlet of the beverage supply valve 5 of the carbonated water supply pipe 26, the carbonated water circulation pipe 30 constituting the carbonated water circulation circuit 39 is connected as described above, and the beverage supply valve 5 is closed. The circulation pump 31 of the carbonated water circulation circuit 39 is operated. As a result, carbonated water in the vicinity of the inlet of the beverage supply valve 5 of the carbonated water supply pipe 26 flows into the carbonated water circulation pipe 30 and enters the carbonated water cooling flow path 9B via the circulation pump 31 and the check valve 32. It flows into the carbonated water supply pipe 23 located at. Here, the carbonated water again flows into the carbonated water cooling channel 9 </ b> B and is efficiently cooled by the cooling action of the cold plate 9. In the supply standby state, the carbonated water carbonated water circuit 39 repeats the circulation. In the present embodiment, since the carbonated water circulation pipe 30 constituting the carbonated water circulation circuit 39 is provided in the vicinity of the inlet of the beverage supply valve 5, the amount of carbonated water remaining in the carbonated water circulation pipe 30 without being circulated is reduced as much as possible. Can be made.

  Thereafter, when the beverage is selected by the selection switch 4 in the standby state as described above, the controller 45 opens the corresponding beverage supply valve 5 and the flow rate regulator 13 of the syrup supply pipe 14 through which the corresponding syrup flows. The beverage is supplied.

  Thereby, the drink produced | generated by mixing the selected drink with a syrup and carbonated water or a syrup and dilution water in the drink supply valve | bulb 5 can be supplied suitably.

  In this way, in the beverage dispenser in which the beverage is cooled by the ice pieces I stored in the ice storage 8, the dead space in the ice storage 8 is reduced as in the present invention, thereby more effectively. The beverage can be cooled.

  In this embodiment, an ice storage 8 is provided on the side of the auger type ice making machine (ice making unit 3), and a beverage dispenser that cools the beverage with the ice stored in the ice storage 8 is cited. The present invention is not limited to this, and the present invention is effective even with only the ice making machine as long as the ice storage 8 is provided on the side of the ice making unit.
