[0021]
The evaporator 17 is connected to a cooling unit (not shown) and has a large number of ice making chambers 21 opening downward. Further, the water tray 18 and the water tank 19 are integrated, and the water stored in the water tank 19 is made by the circulation pump 22 from the injection port (not shown) formed on the surface of the water tray 18 to make the ice of the evaporator 17. Sprayed into the chamber 21, ice cubes 16 are generated in the ice making chamber 21.
[0022]
The water tray 18 is supported via an arm 24 and a coil spring 25, and the arm 24 is rotationally driven by a reduction motor 23. As the arm 24 rotates counterclockwise by the forward rotation of the speed reduction motor 23, the water pan 18 and the water tank 19 tilt as shown in FIG. 1, and the ice cubes generated in the ice making chamber 21 of the evaporator 17 are tilted. 16 falls and is put into the switching machine 14. After the ice cube 16 falls, the speed reduction motor 23 reverses, the arm 24 rotates clockwise, and the water pan 18 and the water tank 19 return to the horizontal position.
[0023]
The ice breaker 12 crushes the ice cube 16 into the ice break 26. As shown in FIG. 2, the ice breaker 12 includes a housing 27 in which an ice breaking cylinder 28 is rotatably disposed. The ice breaking cylinder 28 is driven to rotate by a drive motor 31 via a pulley 29 and a timing belt 30. The A large number of ice breaking blades 32 are planted on the outer periphery of the ice breaking cylinder 28, and the ice breaking blades 32 crush the ice cubes 16 by the rotation of the ice breaking cylinder 28 to generate the ice breaking 26.
[0024]
The switching machine 14 selectively guides the ice cube 16 from the ice making machine 11 to the ice cube storage section 40 or the ice breaker 12 described later of the ice storage 13, and includes a reduction motor 33, a switching plate 34, and a ice cube side. A position detector 35 and an ice break side position detector 36 are provided.
[0025]
As shown in FIG. 2, the switching plate 34 as a switching member is disposed inside the casing 37 and below the shooter 38 fixed to the upper portion of the casing 37. The switching plate 34 is driven forward or reversely by the speed reduction motor 33, and the ice cube side position A for guiding the ice cube 16 introduced into the shooter 38 to the ice cube storage unit 40 of the ice storage 13 and the ice breaker 12. It is positioned at the ice breaking position B leading to
[0026]
The ice cube position detector 35 and the ice break position detector 36 are installed in a casing 37. Among these, the ice cube side position detector 35 contacts the switching plate 34 positioned at the ice cube side position A, and detects that the switching plate 34 is positioned at the ice cube side position A. The ice breaking side position detector 36 abuts on the switching plate 34 positioned at the ice breaking side position B, and detects that the switching plate 34 is positioned at the ice breaking side position B. The detection results of the ice cube position detector 35 and the ice break position detector 36 are transmitted to the control device 15 as shown in FIG.
[0027]
As shown in FIG. 1, the ice storage 13 is divided into a square ice storage part 40 and an ice break storage part 41 by a partition plate 39. The ice cubes 16 made by the ice making machine 11 are stored in the ice cube storage unit 40. In the ice breaking storage unit 41, ice breaks 26 obtained by crushing ice cubes 16 from the ice making machine 11 with the ice breaking machine 12 are stored.
[0028]
An ice cube storage sensor 42 and an ice break storage sensor 43 are installed above the ice cube storage unit 40 and the ice break storage unit 41, respectively. The ice cube ice storage sensor 42 and the ice break ice storage sensor 43 are in a full ice state when, for example, infrared rays emitted from the light projecting unit are blocked by the ice cube 16 or the ice breaker 26 for a certain period of time and do not reach the light receiving unit. It is a sensor to detect. The ice cube storage sensor 42 detects that the ice cube 16 is full in the ice cube storage unit 40, and the ice break sensor 43 detects that the ice break 26 is full in the ice break storage unit 41. Detected. The detection results of the ice cube storage sensor 42 and the ice break storage sensor 43 are transmitted to the control device 15 as shown in FIG.
[0029]
The control device 15 individually controls the operations of the ice making machine 11, the ice breaker 12, and the switching machine 14.
[0030]
That is, the control device 15 guides the ice cube 16 from the ice making machine 11 to the ice cube storage unit 40 or the ice breaker storage unit 41 in the less ice state based on the detection results from the ice cube storage sensor 42 and the ice breaker storage sensor 43. Thus, the position of the switching plate 34 of the switching machine 14 is controlled. In other words, when the ice cube storage sensor 42 does not detect the full ice state of the ice cube 16, the control device 15 drives and controls the reduction motor 33 of the switching machine 14 to position the switching plate 34 at the ice cube side position A. Then, the ice cubes 16 from the ice making machine 11 are put into the ice cube storage unit 40 in the ice storage 13. When the ice-breaking ice storage sensor 43 does not detect the full ice condition of the ice-breaking ice 26, the control device 15 drives and controls the speed reduction motor 33 of the switching machine 14 to position the switching plate 34 at the ice-breaking side position B. The ice cubes 16 from 11 are put into the ice breaker 12, and the ice breaks 26 crushed by the ice breaker 12 are put into the ice breaker storage section 41 in the ice storage 13. Further, the control device 15 stops the reduction motor 33 when the switching plate 34 is detected by the ice cube side position detector 35 or the ice breaking side position detector 36.
[0031]
The control device 15 puts the ice making machine 11 into an operation standby state when either the ice cube ice storage sensor 42 or the ice break ice storage sensor 43 has not detected the full ice state, and detects the ice cube side position detector 35 or the ice break side position. When the device 36 detects that the switching plate 34 of the switching machine 14 is in the ice cube side position A or the ice breaking side position B, the ice making machine 11 is operated. Further, the control device 15 stops the ice making machine 11 when both the ice cube storage sensor 42 and the ice breaking ice storage sensor 43 detect the full ice state. Accordingly, the ice making machine 11 is stopped when the ice cube 16 is filled in the ice cube storage unit 40 of the ice storage 13 and the ice breaker 26 is full of ice in the ice break storage unit 41, but the ice cube storage unit 40 is stopped. The ice cubes 16 or the ice breaker 26 is taken out from the ice breaker storage unit 41, and either the ice cube storage unit 40 or the ice breaker storage unit 41 is in a less ice state, and the switching plate 34 of the switching machine 14 is It operates when it is positioned at the ice side position A or the ice break position B.
[0032]
Further, the control device 15 detects that the switching plate 34 of the switching machine 14 is positioned at the ice breaking position B by the ice breaking side position detector 36 and the ice breaking ice storage sensor 43 detects the full ice condition of the ice breaking 26. When the ice breaker 12 is not in operation, the ice breaker 12 is operated, and when the ice breaker storage sensor 43 detects a full ice state in the ice breaker storage unit 41, the ice breaker 12 is stopped. Thereby, the ice breaker 12 is operated only when the ice breaker 26 is stored in the ice breaker storage unit 41 in the less ice state.
[0033]
Further, the control device 15 starts the turning operation of the switching plate 34 in the switching machine 14 based on the detection result from the ice cube storage sensor 42 or the ice breaking ice storage sensor 43, and the ice cube side position is maintained even after a predetermined time has elapsed. When the detector 35 or the ice breaking side position detector 36 does not detect the switching plate 34, the ice making machine 11, the ice breaking machine 12, and the switching machine 14 are stopped. The predetermined time is sufficient for the switching plate 34 to rotate from the ice cube side position A to the ice breaking side position B or from the ice breaking side position B to the ice cube side position A by driving the speed reduction motor 33.
[0034]
Next, the control of the control device 15 will be described in detail with reference to FIG.
[0035]
(1) First, the control device 15 determines whether or not the ice breaking side ice making flag is set (S1), and when it is determined that the flag is not set, the ice cube storage unit 40 of the ice storage 13 is determined. Is determined by the detection result of the ice cube storage sensor 42 (S2).
[0036]
(2) When the ice cube storage unit 40 is not full, the control device 15 determines whether or not the switching plate 34 of the switching device 14 is in the ice cube position A by the ice cube position detector 35 ( S3). The control device 15 counts a built-in timer (not shown) when the switching plate 34 is not in the ice cube side position A (S4), and almost the same time (t seconds) has elapsed after the timer starts counting. If it has not elapsed, the speed reduction motor 33 of the switching machine 14 is immediately rotated forward to rotate the switching plate 34 toward the ice cube side position A (S6).
[0037]
(3) The control device 15 sequentially executes steps S1 to S6 described above, and clears the built-in timer when it is determined in step S3 that the switching plate 34 of the switching machine 14 is positioned at the ice cube side position A. (S7) The forward rotation drive of the reduction motor 33 of the switching machine 14 is stopped almost simultaneously (S8), the ice making machine 11 is operated, and the ice making process of the ice cube 16 is executed (S9). Thereby, the ice cubes 16 made by the ice making machine 11 are put into the ice cube storage unit 40 of the ice storage 13 through the switching plate 34 of the switching machine 14 and stored.
[0038]
(4) When the predetermined time (t seconds) has elapsed since the timer was counted in step S4, that is, the control device 15 rotates the speed reduction motor 33 in order to rotate the switching plate 34 toward the ice cube side position A. When t seconds have elapsed, an error is displayed because the switching plate 34 is not positioned at the ice cube side position A (S10), and the ice making machine 11, the ice breaker 12 and the switching machine 14 are stopped almost simultaneously. (S11), the built-in timer is cleared.
[0039]
(5) When the ice cube storage sensor 42 detects that the ice cube storage unit 40 of the ice storage 13 has become full in step S2, the control device 15 causes the ice break storage unit 41 of the ice storage 13 to be full. Whether or not it is ice is determined based on the detection result of the ice-breaking ice storage sensor 43 (S12).
[0040]
(6) When the ice breaking storage unit 41 is not full, the control device 15 sets the ice breaking side ice making flag (S13), and subsequently determines whether or not the switching plate 34 of the switching machine 14 is at the ice breaking side position B. Determination is made by the side position detector 36 (S14). The control device 15 counts a built-in timer when the switching plate 34 is not in the ice cube side position A (S15), and almost simultaneously, it is determined whether or not a predetermined time (t seconds) has elapsed after the timer starts counting. When the determination is made (S16) and the time has not elapsed, the speed reduction motor 33 of the switching machine 14 is immediately reversed to rotate the switching plate 34 toward the ice breaking position B (S17).
[0041]
(7) The control device 15 sequentially executes the above steps S1 and S12 to S17. At this time, the control device 15 determines that the ice-breaking ice making flag is set in step S1, and therefore executes step S12 immediately without executing step S2. The control device 15 clears the built-in timer when it is determined in step S14 that the switching plate 34 of the switching machine 14 is positioned at the ice breaking side position B (S18), and almost simultaneously, the speed reduction motor 33 of the switching machine 14 is turned off. The reverse drive is stopped (S19), the ice breaker 12 is driven, and the ice breaking process is performed (S20). As a result, the ice cubes 16 made by the ice making machine 11 are put into the ice breaker 12 via the switching plate 34 of the changeover machine 14, and are crushed by the ice breaker 12 to become the ice breaker 26, thereby forming the ice storage 13. Are put into the switching machine 14 and stored in ice.
[0042]
(8) The control device 15 reverses the speed reduction motor 33 to rotate the switching plate 34 toward the ice breaking position B when the predetermined time (t seconds) has elapsed since the timer was counted in step S15. When t seconds have elapsed, an error is displayed because the switching plate 34 is not positioned at the ice breaking side position B (S21), and at the same time, the ice making machine 11, the ice breaking machine 12, and the switching machine 14 are stopped (S22). ) Clear the built-in timer.
[0043]
(9) At step S12, the control device 15 clears the ice-breaking ice making flag when the ice-breaking ice storage sensor 43 detects that the ice-breaking storage part 41 of the ice storage 13 is full (S23). The ice making machine 11 and the ice breaker 12 are stopped to perform an ice storage process (S24).
[0044]
Therefore, according to the above embodiment, the following effects (1) to (3) are obtained.
[0045]
(1) A square ice storage sensor 42 that detects the full ice state of the ice cube 16 in the ice cube storage section 40 of the ice storage 13 and a full ice state of the ice break 26 in the ice break storage section 41 of the ice storage 13 are displayed. Each ice-breaking ice storage sensor 43 to be detected is installed, and the control device 15 that controls the switching machine 14 is based on the detection results from the ice-ice storage sensor 42 and the ice-breaking ice storage sensor 43, and the ice-ice storage section 40 in the less ice state. Alternatively, since the position of the switching plate 34 is controlled so as to guide the ice cube 16 to the ice breaking storage unit 41 side, either the ice cube storage unit 40 or the ice breaking storage unit 41 of the ice storage 13 becomes full. At that time, the position of the switching plate 34 of the switching machine 14 is controlled, and the ice cubes 16 from the ice making machine 11 are guided to the ice cube storage unit 40 or the ice breaker storage unit 41 in the less ice state. As a result, the ice cube storage unit 40 and the ice break storage unit 41 can be filled in a well-balanced state, and the ice cube 16 is stored in the ice cube storage unit 40 of the ice storage 13 and the ice break 26 is stored in the ice break storage unit 41 efficiently. it can.
[0046]
(2) The switching machine 14 includes a square ice side position detector 35 for detecting that the switching plate 34 is positioned at a position for guiding the ice cube 16 to the ice cube storage section 40 in the ice storage 13, and a switching plate 34. Since the ice breaker position detector 36 for detecting that the ice cube 16 is positioned at the position where the ice cube 16 is guided to the ice breaker 12 is provided, the appropriate position of the switching plate 34 (the ice break position A or the ice break position B). Can be accurately detected.
[0047]
(3) If the ice cube side position detector 35 or the ice breaking side position detector 36 does not detect the position of the switching plate 34 after a predetermined time has elapsed since the switching plate 34 of the switching machine 14 has been operated, some sort of failure has occurred. Since it can be determined that it has occurred, the safety of the ice-breaking ice storage device 10 can be improved by the control device 15 stopping the ice making machine 11, the ice breaking machine 12, and the switching machine 14 at this time.
[0048]
As mentioned above, although this invention was demonstrated based on one Embodiment, this invention is not limited to this.
[0049]
For example, in the ice storage 13, the ice cube storage sensor 42 is installed at a position higher than the ice break sensor 43. However, the ice cube storage sensor 42 and the ice break sensor 43 may be the same height. Further, the ice-breaking ice storage sensor 43 may be positioned higher than the ice cube storage sensor 42.
[0050]
Also, from FIG. 4, in this ice breaking ice storage device 10, the ice cube 16 preferentially stores ice in the ice cube storage section 40 of the ice storage 13 is described, but step S <b> 2 in FIG. 4 and steps related thereto are shown. S3 to S11, step S12, and steps S13 to S24 related thereto may be interchanged so that the ice break 26 is preferentially stored in the ice break storage unit 41. However, in this case, in steps S1 and S13 and the S arm 24, the ice breaking side ice making flag is set as a square ice side ice making flag, and step S13 is inserted between steps S2 and S3.
