TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for detecting an ice making level of an ice making machine.
[0002]
[Prior art]
An ice maker is an apparatus for making ice by supplying supplied ice making water, and FIG. 1 shows a conventional ice maker (see Patent Document 1).
[0003]
As shown in FIG. 1, the conventional ice maker includes an ice maker main body 10 and an ice maker unit 20. An ice storage 11 for storing ice produced by the ice making unit 20 is provided inside the ice making machine main body 10. A refrigeration system 30 including a compressor 31 and a condenser 32 is arranged below the ice storage 11. A water supply pipe 12 for supplying ice making water to the ice making unit 20 and a drain pipe 13 for discharging water not frozen in the ice making unit 20 to the outside of the ice making machine 10 are connected to the ice making machine main body 10. Is done. The water supply pipe 12 extends from a water supply facility (not shown) to the ice making unit 20, and the drain pipe 13 extends from a water collecting part 14 attached to the ice storage 11 to a drainage facility (not shown).
[0004]
As shown in FIG. 2, the ice making unit 20 includes a water tray 21 in which water is stored, a cooling plate 22, and an evaporating tube 23. The water tray 21 is connected to a holding member 25 that is rotatably held by a turning shaft 24, and a swing plate 26 is mounted inside the holding member 25. The holding member 25 rotates the water tray 21 in one direction while rotating about the turning shaft 24 by the turning motor AM to discharge the water remaining in the water tray 21. The swing plate 26 removes bubbles in the water by swinging the water in the water tray 21 while swinging up and down by the swing motor RM. On one side of the water tray 21, a drain guide plate 27 for guiding water discharged from the water tray 21 to the water collecting section 14 is attached.
[0005]
A number of cooling projections 28 are provided below the cooling plate 22 so that ice is immersed in water and ice grows therearound.
[0006]
The evaporating tube 23 is provided on the upper surface of the cooling plate 22 and is connected to the refrigeration system 30. A refrigerant flows in the evaporating pipe 23, and the cooling plate 22 and the cooling projections 28 are cooled by heat exchange of the refrigerant.
[0007]
According to the above configuration, water freezes around the cooling projection 28 cooled to a temperature below the freezing point by heat exchange of the refrigerant. When ice of a predetermined size is generated around the cooling protrusion 28, high-temperature refrigerant discharged from the compressor 31 is directly supplied into the evaporating pipe 23 without passing through the condenser 32, and is generated. Ice is dropped from the cooling projections 28. Then, the water tray 21 is tilted about the turning shaft 24 together with the holding member 25 by the turning motor AM. Therefore, the generated ice falls into the ice storage 11, and the remaining free water in the water tray 21 is discharged to the drainage facility through the drainage pipe 13.
[0008]
By repeating such an ice making process, the ice maker operates so that a fixed amount of ice can always be stored in the ice storage 11.
[0009]
However, the ice making unit having the above configuration needs to detect the size of ice that is made during the ice making process.
[0010]
There is also a need for an improved ice making unit that includes means for detecting the position of the water tray and the like so that the ice making process can be performed more easily and quickly.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of an ice making device for an ice making machine according to the present invention will be described in detail with reference to the accompanying drawings.
[0030]
Referring to FIGS. 3, 4 and 5, the ice making device of the ice making machine according to the embodiment of the present invention includes a holding frame body 60 rotatably disposed above an ice storage tank attached to the ice making machine main body. A base frame 70 disposed above the holding frame 60; a cooling plate 80 disposed above the base frame 70; and an evaporating pipe 90; and a cover member 100 on which the holding frame 60 is supported. And a posture detecting unit for detecting the posture of the holding frame body 60 with respect to the cover member 100.
[0031]
The holding frame body 60 is disposed at an upper portion of the ice storage tank 51 so as to be rotatable and returnable at a predetermined angle, preferably about 90 ° below. The holding frame body 60 has a plate-shaped body 61 and a pair of shaft portions 63 provided on one side of the body 61. The shaft 63 is rotatably connected to the cover member 100. A drive shaft 66 for rotating the holding frame body 60 is connected to one of the pair of shaft portions 63. The drive shaft 66 is rotated by a drive motor (not shown).
[0032]
The cover member 100 to which the shaft portion 63 is connected is provided above the ice storage tank of the ice making machine main body. The cover member 100 has a plurality of connecting legs 102 extending downward.
[0033]
The base frame body 70 is disposed above the holding frame body 60 so as to be able to move up and down to a predetermined height. The base frame body 70 has a plurality of ice water grooves 71 formed therein for storing ice making water. The base frame 70 is connected to the holding frame 60 by a guide member 111 and a spring 112 described later, and rotates together with the holding frame 60. Further, in the base frame body 70, a drainage channel 73 for draining water remaining in the ice water groove 71 after the ice making process is formed at one side edge of the upper surface. When the base frame 70 rotates downward by 90 °, water is discharged from the drainage channel 73. A drainage pipe (not shown) for collecting drained water is provided in the ice storage tank.
[0034]
A cooling plate 80 is provided above the base frame body 70. The cooling plate 80 is made of a metal material having a good thermal conductivity, and a plurality of cooling projections 81 immersed in the water stored in the ice water groove 71 are formed at a lower portion. An evaporating tube 90 is connected to the upper surface of the cooling plate 80. The evaporating tube 90 is connected to a refrigeration system (not shown). When a low-temperature refrigerant is supplied from the refrigeration system to the evaporating tube 90, the cooling plate 80 falls to a low temperature. At this time, icing is repeatedly performed by repeatedly immersing the cooling projections 81 in water, and as a result, an ice block becomes large. Next, when the ice block grows to a certain size or more on the cooling protrusion 81, the high temperature gas is temporarily supplied to the evaporating tube 90, so that the ice block falls from the cooling protrusion 81.
[0035]
On the other hand, freezing of ice around the cooling projections 81 is performed by repeatedly immersing the cooling projections 81 in the ice water grooves 71 by raising and lowering the base frame body 70.
[0036]
Thus, the elevating unit for elevating the base frame body 70 is further provided. The lifting unit holds a plurality of guide members 111 provided between the base frame body 70 and the holding frame body 60, a spring 112, a pair of cams 113 provided above the base frame body 70, and the cams 113. A cam shaft 114 and a cam drive motor 115 are provided. The guide member 111 has one end fixed to a lower portion of the base frame body 70 and the other end inserted through the holding frame body 60. The guide member 111 is provided with a spring 112 extrapolated. The guide member 111 guides the elevating movement of the base frame body 70. When the guide member 111 is lowered, the spring 112 is compressed, and the compressed spring 112 provides a lifting force to the base frame body 70.
[0037]
The pair of cams 113 are arranged along the longitudinal direction of the base frame body 70 so as to be in contact with the upper surfaces of both ends, and each is fixed to the cam shaft 114. The camshaft 114 is connected to a cam drive motor 115 held on a side wall of the cover member 100 to transmit power. When the cam 113 rotates when the cam shaft 114 rotates, the base frame 70 can be moved up and down by the cam operation of the cam 113.
[0038]
The detection unit is for detecting the attitude of the holding frame body 60 with respect to the cover member 100. Such a detection unit includes a first detection unit 120 for detecting whether or not the holding frame body 60 is positioned in a posture aligned with the cover member 100, and a predetermined angle by rotating the holding frame body 60 downward, Preferably, a second detection unit 130 for detecting whether the rotation has been completed by 90 ° is provided.
[0039]
The first detection unit 120 includes a first sensor 121 attached to a side surface of the cover member 100, and a first detection element 123 attached to the holding frame body 60. The first sensor 121 may be a sensor that can detect a magnetic force acting between the metal material or the magnet when facing the metal material or the like at a predetermined interval. Therefore, the first sensing element 123 is made of a metal material so that it can be detected by the first sensor 121 when facing the first sensor 121 at a predetermined interval. A first support boss 64 for supporting the first detection element 123 is protruded from the other side surface 61b of the holding frame body 60 at a predetermined height. That is, the first support boss 64 protrudes from the opposite side to one side surface 61 a of the holding frame body 60 on which the shaft portion 63 is formed, that is, from the other side surface 61 toward the cover member 100. Preferably, the first support boss 64 is provided at a corner near the first sensor 121 in the other side surface 61b. When the holding frame body 60 descends and then returns to a horizontal state again, the first sensing element 123 provided at the upper end of the first support boss 64 faces the first sensor 121, and between them. When the first sensor 121 detects that a magnetic force equal to or more than the reference value is applied, it is determined that the holding frame body 60 has returned to normal, and the next operation can be performed.
[0040]
The second detection unit 130 is for detecting whether or not the holding frame body 60 has been rotated downward and moved a predetermined angle, that is, 90 degrees completely. The second detection unit 130 has a second sensor 131 attached to one side surface 101 of the cover member 100 and a second sensor 131 attached to one side surface 61a of the holding frame body 60 so as to correspond to the second sensor 131. Including the sensing element 133. The second sensor 131 has the same function as the first sensor 121, and the second sensing element 133 is formed of the same material as the first sensing element 123. A second support boss 65 for supporting the second detection element 133 is protruded from the one side surface 61a of the holding frame body 60 at a predetermined height. The second detection element 133 is supported by being fitted into a housing groove provided at the upper end of the second support boss 65. As shown in FIG. 5, when the holding frame body 60 rotates downward by 90 °, the second detection element 133 faces the second sensor 131 at a predetermined interval. Therefore, the second sensor 131 detects the magnitude of the magnetic force acting between the second sensor 131 and the second detection element 133 to detect the attitude of the holding frame body 60.
[0041]
Further, the apparatus further includes a third detection unit 140 for detecting an elevation height of the base frame body 70 when performing the ice making process while moving the base frame body 70 up and down. The third detection unit 140 can detect the size of the ice that forms around the cooling projection 81 as a result by detecting the elevation height of the base frame body 70.
[0042]
The third detection unit 140 includes a third sensor 141 attached to a side surface of the cover member 100, and a third detection element 143 attached to the base frame body 70 so as to correspond to the third sensor 141. The third sensor 141 is attached to a position adjacent to the first sensor 121. The third sensor 141 detects a change in magnetic force acting between the third sensor 141 and the third detection element 143 when the base frame body 70 moves up and down. Therefore, when the size of the ice frozen around the cooling protrusion 81 increases, the height of the base frame body 70 gradually decreases, and as a result, the magnetic force detected by the third sensor 141 gradually decreases. The size of the ice can be measured by detecting such a change in the magnetic force. On the other hand, a third support boss 75 having an accommodation groove for accommodating the third detection element 143 is further provided on one side of the base frame body 70. The third support boss 75 protrudes toward a side surface of the base frame body 70.
[0043]
Further, a fourth detection unit 150 for detecting the position of the cam 113 is further provided. The fourth detection unit 150 includes a fourth sensor 151 mounted on the upper surface of the cover member 100 and a fourth detection element 153 mounted on the cam 113 or the cam shaft 114 so as to correspond to the fourth sensor 151. I do. In the present embodiment, as shown in FIG. 6, the fourth detection element 153 is fitted in a housing groove formed in a fourth support boss 113a formed integrally with the cam 113. The fourth detection element 153 is fixed in position with respect to the posture of the cam 113, and rotates together. Therefore, when the cam 113 makes one rotation, the shortest distance and the longest distance are brought into contact with and separated from the fourth sensor 151 once. Preferably, the fourth sensing element 153 may be mounted closer to a short radius with respect to the rotation center of the cam 113. For this reason, the fourth support boss 113a is located on an imaginary line connecting the long radius and the short radius of the cam 113, and protrudes toward the side surface of the cam 113 near the short radius. Therefore, when the short radius of the cam 113 moves upward, the distance between the fourth sensor 151 and the fourth detecting element 153 becomes the shortest, and when it moves backward, it becomes the farthest. Of course, the fourth sensor 151 can also read the position of the cam 113, that is, the posture, by detecting the magnetic force acting between the fourth sensor 151 and the fourth detection element 153.
[0044]
The ice making process of the ice making device having the above-described configuration according to the embodiment of the present invention will be described as follows.
[0045]
First, as shown in FIGS. 4 and 6, the ice making process starts in a state where ice water is stored in the ice water groove 71 of the base frame body 70. That is, a low-temperature refrigerant is supplied to the evaporating tube 90, and the cooling projections 81 of the cooling plate 80 are cooled to a low temperature. In this state, the cam 113 is rotated. Then, the base frame body 70 is repeatedly moved up and down by the action of the cam 113. As a result, the cooling projections 81 are repeatedly immersed in the ice water in the ice water grooves 71, and ice water is repeatedly applied around the cooling projections 81, freezes, and gradually grows into ice blocks. In this case, the magnetic force between the detection elements 143 and 153 detected by the third sensor 141 and the fourth sensor 151 shows a value that is repeatedly symmetrical as shown in FIG. That is, when the base frame 70 rises by the driving action of the cam 113, the magnetic force detected by the third sensor 141 increases, and the magnetic force detected by the fourth sensor 151 decreases. When the base frame body 70 descends, a magnetic force having a magnitude opposite to that described above is measured. Such a cycle is repeated for a predetermined time based on one rotation cycle (t1) of the cam 113.
[0046]
On the other hand, as shown in FIG. 7, when the ice becomes large to a certain size during the repetition of the above-mentioned operation, the base frame 70 cannot be lifted to a certain extent because of the ice. Even in this case, the cam 113 continues to rotate. Accordingly, at this time, the magnetic force measured by each of the fourth sensor 151 and the third sensor 141 is asymmetric with respect to each other as shown in a section B in FIG. This is because the base frame body 70 must rise to the highest position with the short radius of the cam 113 abutting on the base frame body 70, but when the size of the ice increases to a desired size, the ice is hindered by the ice. This is because the base frame body 70 cannot be lifted. Even though the fourth sensor 151 measures the lowest magnitude of magnetic force between the fourth sensor 151 and the fourth sensing element 153, the third sensor 141 has a magnitude significantly smaller than the magnitude of the magnetic force measured in the section A. It measures the magnetic force. As described above, the control unit detects that the ice has been made to the desired size from the detection signal that is shifted from the section A to the section B. Of course, the transition is not instantaneous from the section A to the section B, but gradually.
[0047]
On the other hand, when it is determined that the ice making has been completed, the control unit stops driving the cam 113. Then, after the locked state of the base frame body 70 is released, the drive shaft 66 is forcibly driven to rotate the base frame body 90 by 90 ° to descend. Then, as shown in FIG. 9, the second sensor 131 and the second detecting element 133 face each other at a predetermined distance. Accordingly, the second sensor 131 measures the magnetic force acting between the second sensor 131 and the second sensing element 133, and based on the measured information, the control unit lowers the holding frame body 60 and the base frame body 70 by 90 °. It is determined whether or not it has been done.
[0048]
When it is confirmed that the holding frame body 60 and the base frame body 70 have rotated by 90 °, a high-temperature gas is supplied to the evaporating tube 90 to heat the cooling projections 81 of the cooling plate 80. Then, the ice blocks that have been frozen around the cooling projections 81 melt and fall.
[0049]
After a certain time has passed and all the ice has fallen, the drive shaft 66 is rotated to return the holding frame body 60 and the base frame body 70 to their original positions, that is, the horizontal position. When the holding frame body 60 returns to the original position, the second detection element 133 is located so as to face the first sensor 121. As a result, the first sensor 121 detects the magnetic force acting between the first sensor 121 and the first detection element 133, and determines whether or not the holding frame body 60 has returned based on the magnitude of the detected magnetic force. become. Next, when it is confirmed that the holding frame body 60 has completely returned, the ice making process of freezing ice around the cooling projections 81 is repeatedly performed.
[0050]

It is clear that a person skilled in the art can conceive various changes or modifications within the scope of the technical idea described in the claims, and these are naturally included in the technical idea of the present invention. It is understood to belong.

【The invention's effect】
As described above, according to the ice making device of the ice making machine of the present invention, it is possible to detect the horizontal and vertical states of the holding frame body and easily confirm the malfunction or failure of the ice making device.
[0052]
In addition, the size of the ice that freezes is continuously detected to prevent overloading and malfunctioning in advance, and unnecessary waiting time can be reduced, thus shortening the ice making time. There is an advantage that you can do it.
