DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing shaved ice by rapid cooling, and more particularly to forming an ice layer on the outer peripheral surface of a rotary drum equipped with rapid cooling means to obtain fine and uniform high-quality snow-like ice. The present invention relates to a shaved ice producing apparatus capable of performing the above.

[0002]

2. Description of the Related Art Conventionally, there is an ice scraper which obtains snow-like ice by applying water to an inner surface of a vertically arranged cooling drum. In this method, a cooling coil and a screw-shaped ice-breaking blade are installed rotatably in a vertical cylinder with a discharge port in the upper part, and the ice formed from the lower part is swept while the screw-type blade rotates. And forced the water to be discharged toward the upper ice outlet.

[0003] As another conventional shaved ice making apparatus, an ice layer is formed by spraying water on an inner surface of a vertically arranged cylindrical cooling drum, and an ice-cutting blade installed inside the cylindrical cooling drum rotates. There was a device for scraping off the ice layer on the inner surface of the cylindrical cooling drum to obtain shaved ice. However, according to such a conventional apparatus, since water is sprayed on the inner surface of the cylindrical drum and water flows along the inner surface of the cooling drum and freezes, the ice layer is thinner on the upper side and lower on the lower side. Is formed thick. Therefore, when an ice layer with a different thickness in the vertical direction is scraped out with an ice-sharpening blade, a large load is applied to the lower part of the ice-sharpening blade, which damages the ice-shading blade, and the size of the ice is not uniform. There is a problem that it is difficult to obtain good quality shaved ice by mixing different types of ice.

An example for solving such a conventional problem is disclosed in Korean Utility Model Publication No. 93-306. The shaved ice manufacturing apparatus disclosed in this publication forms an ice layer on the outer surface of a cooling drum to obtain snow-like ice. As shown in FIGS. 15 and 16, the apparatus includes a cooling drum 1 rotatably supported by a rotating shaft 1 a and a hollow shaft 1 b, a cooling cylinder 2 installed concentrically inside the cooling drum 1, A cooling coil 3 mounted inside the cooling cylinder 2 via a hollow shaft 1b, a motor 4 for rotating the cooling drum 1, a driving sprocket 4a fixed to the shaft of the motor 4, and a rotating shaft 1a of the cooling drum 1 Driven sprocket 1c fixed to the shaft, a chain 5 wrapped around the driving sprocket 4a and the driven sprocket 1c, and a water supply cylinder containing water therein and disposed so that the lower side of the cooling drum 1 is soaked in water. 6, a selective blade 6a for equalizing water adhering to the outer peripheral surface of the cooling drum 1, and a drum having one end inclined upward at a predetermined angle to scrape an ice layer formed on the outer peripheral surface of the cooling drum 1. Face to face And a fixed Kezukori blade 7 for the so that. Then, when the cooling drum 1 is sufficiently cooled, the motor 4 is driven to rotate the cooling drum 1 clockwise, and water adheres to the drum surface through a water supply cylinder 6 disposed therebelow. At this time, the attached water is uniformly attached to the drum surface by the selective blade 6a, and the water attached to the outer surface of the drum is rapidly taken away heat while rotating with the cooling drum 1 to form an ice layer on the outer peripheral surface of the cooling drum 1. Form. Thereafter, the rapidly frozen ice layer is scraped off from the outer peripheral surface of the cooling drum 1 by the ice-cutting blade 7 to produce shaved ice which is fine snow-like ice.

[0005]

However, according to the conventional shaved ice manufacturing apparatus constructed as described above, the cooling cylinder 2 and the cooling coil 3 are separately manufactured to a predetermined size, and are formed inside the cooling drum 1. It has to be assembled, and it is necessary to separately install a selective blade 6a for equalizing the thickness of the attached water to a uniform thickness.

Further, since the lower side of the cooling drum 1 is always in contact with the water in the water supply tube 6, the temperature of the water in the water supply tube 6 decreases and the newly supplied water Has a problem that the ice layer formed on the outer peripheral surface of the cooling drum 1 becomes non-uniform.

Further, since the lower side of the cooling drum 1 is in constant contact with the water in the water supply cylinder 6, not only the thermal efficiency of the cooling drum 1 is reduced, but also the cooling drum 1
There is a problem that water adhering to the side of the device freezes to form an ice block, which adversely affects the operation of the device.

Further, since a predetermined amount of water is always contained in the water supply cylinder 6 in a stagnant state, there is a sanitary problem that dust and foreign matter are mixed in and contaminate the water in the water supply cylinder 6. was there.

Further, according to the conventional apparatus, the ice-cutting blade 7 is installed inclined at a predetermined angle in the upward direction so as to scrape the ice layer formed on the outer peripheral surface of the cooling drum 1. In some cases, part of the shaved ice was frozen on the upper surface of the ice-sharpening blade 7. This includes the problem of inducing vibration and sinking of the ice-cutting blade 7 together with vibration due to the operation of the apparatus by applying the own weight of the ice-cutting blade. There is a problem that the ice-cutting blade itself may be damaged or the ice-cutting blade itself may be damaged.

Further, in the power transmission system using the chain 5 for rotating and driving the cooling drum 1, since lubricating oil must be supplied, there is a possibility that the lubricating oil may be mixed into the shaved ice.

The operation of the apparatus for producing shaved ice according to the first embodiment of the present invention will be described below. First, when the cooling drum 21 is sufficiently cooled by the cooling means 23, the motor 25 is rotated by a control signal from a control unit (not shown) and is cooled via the driving pulley 26, the timing belt 27 and the driven pulley 24. The drum 21 is rotated counterclockwise as shown. At this time, the water supply suit 2 of the water supply means 28 installed so as to be in contact with the outer peripheral surface of the cooling drum 21
Water is supplied into 8a via a water supply pipe 28b. When the surface of the supplied water is sensed by the water surface sensing means 28c arranged at a predetermined height in the water supply suit 28a, a sensing signal is sent to a control unit (not shown), and the control unit A control valve (not shown) is controlled to adjust the supply amount of water. The water supplied to the space formed between the water supply suit 28a and the outer peripheral surface of the cooling drum 21 continuously adheres to the outer peripheral surface of the rotating cooling drum 21 and rapidly freezes to form an ice layer. At this time, the thickness of the ice layer formed on the outer peripheral surface of the cooling drum 21 is controlled by the control unit.
It is adjusted by changing the rotation speed of. Thereafter, the ice layer formed on the outer peripheral surface of the cooling drum 21 is scraped by the ice-cutting blade 29, and the snow-like ice obtained is dropped and collected in the storage container 30 disposed below the cooling drum 21. .

According to the shaved ice manufacturing apparatus according to the first embodiment of the present invention, a required amount of water is supplied to the water supply suit and brought into contact with the outer peripheral surface of the cooling drum 21. Therefore, the contact portion between the cooling drum and the supply water is extremely small as compared with the conventional apparatus, and the loss of cool air of the cooling drum is prevented, so that the cooling efficiency of the cooling drum 21 can be prevented from lowering. Further, since water is brought into contact only with the outer peripheral surface of the cooling drum 21 where the ice layer is formed, ice is not formed on the side surface of the cooling drum unlike the conventional apparatus.

In addition, only a necessary amount of water is supplied to the water supply suit by the flow control valve and the water level sensing means in accordance with the rotation speed of the cooling drum.
The temperature of the supplied water becomes uniform, whereby the freezing speed of the water adhering to the outer peripheral surface of the drum becomes almost constant. Therefore, it is possible to form an ice layer having a uniform thickness on the outer peripheral surface of the cooling drum 21. it can. As a result, it is not necessary to separately install and assemble a cooling cylinder and a selective blade as used in the conventional apparatus, so that the manufacturing cost of the shaved ice manufacturing apparatus can be reduced.

Further, according to the apparatus of the first embodiment, since the ice-cutting blade 29 is installed at a predetermined position on the side surface of the cooling drum 21 and is inclined downward by a predetermined angle, the ice-cutting blade 29 No powder accumulates, and therefore, the weight of the ice-cutting blade does not increase as in conventional devices, and does not damage the surface of the cooling drum or the ice-cutting blade itself.

Further, as a transmission element for transmitting power to the cooling drum 21, a medical or food belt, which is a material harmless to the human body, that is, a belt made of polyurethane, polyester, garbage, an ozone prevention belt, or the like is used. The use of a belt-type transmission means and the use of oil-less bearings on the rotating shaft eliminates the problem of hygiene caused by mixing of lubricating oil, which has been a problem with conventional chain-driven transmissions. it can.

Next, the second embodiment of the shaved ice producing apparatus according to the present invention will be described.
An embodiment will be described with reference to FIGS. In the following description of the second embodiment, the points different from the first embodiment will be mainly described. However, the same components as those of the first embodiment will be denoted by the same reference numerals and detailed description will be omitted. Omitted. FIG. 5 is a schematic diagram showing the configuration of a second embodiment of the shaved ice production apparatus according to the present invention, and FIG.
FIG. 6 is an enlarged perspective view showing the water supply means of FIG. 5.

5 and 6, reference numeral 30 denotes a water supply means, 31 denotes a water supply pipe, 32 denotes an injection nozzle, 33
Denotes a reflection plate, and denotes a pressure sensing means.

As shown in the figure, the water supply means 30 is provided at a predetermined position above the cooling drum 21 and has a water supply pipe 31 provided with injection nozzles 32 arranged at regular intervals in a line in the longitudinal direction. A reflection plate 33 installed on the side of the water supply pipe 31 opposite to the injection nozzle 32 for receiving the water injected from the injection nozzle 32 and guiding the water to flow uniformly on the outer peripheral surface of the cooling drum 21; A pressure sensor 34 is installed at a predetermined position on the pipe of the pipe 31 and detects the pressure of the supplied pressure water.

Then, the sufficiently cooled cooling drum 21
Is rotated in the counterclockwise direction as shown in FIG.
1 is supplied with the pressurized water, and the pressurized water is jetted through a plurality of jet nozzles 32 installed on the outer peripheral portion of the water supply pipe 31 in the length direction. The jetted water is uniformly and widely dispersed on the inner surface of the reflector 33, flows along the inner surface, and rotates through the edge of the reflector 33 in contact with the outer surface of the cooling drum 21. Adheres continuously to At this time, the pressure of the pressurized water in the water supply pipe 31 is sensed by the pressure sensing means 34, and the control unit (not shown) controls the control valve (not shown) based on the sensed signal to jet the water. The amount of water injected from the nozzle 32 is adjusted. The water adhering to the outer peripheral surface of the cooling drum 21 is rapidly frozen to form an ice layer, and then, as in the first embodiment, the ice layer is scraped off by an ice-sharpening blade 29 to remove snow-like ice. To manufacture.

According to the apparatus of the second embodiment configured as described above, the water is indirectly applied to the cooling drum by the water supply means in a jetting manner, and thus the apparatus is described in the first embodiment. In addition to the effects, it has the following additional advantages.

Unlike the case where a fixed amount of water is stored in a container installed in contact with the cooling drum, a predetermined amount of water is jetted and supplied using a nozzle, and water flowing down the reflector plate is directly supplied to the cooling drum. Since it is attached to the outer peripheral surface and freezes rapidly, the cooling efficiency of the cooling drum is further improved as compared with the case of the first embodiment. Further, since water for adhering to the cooling drum does not stand by, that is, does not stagnate, foreign matter does not enter and the problem of hygiene can be solved.

Next, the third embodiment of the shaved ice producing apparatus according to the present invention will be described.
An embodiment will be described with reference to FIGS. In the following description of the third embodiment, points different from the first embodiment and the second embodiment will be mainly described.
The same components as those of the embodiment and the second embodiment are denoted by the same reference numerals, and the detailed description is omitted. FIG. 7 is a schematic view showing a configuration of a third embodiment of a shaved ice production device according to the present invention, and FIG. 8 is a perspective view showing a water supply unit of FIG.

7 and 8, reference numeral 40 is a water supply means, 41 is a water supply tank, 42 is a water outlet, 43 is a gate valve, 44 is a water supply pipe, 45 is a discharge pipe, 46 is a drain pipe, 47 denotes a drain valve, and 48 denotes a flow guide.

The water supply means 40 includes a water supply tank 41 for temporarily storing water supplied through a water supply pipe 44, and a water supply tank 4
A water outlet 42 formed at a predetermined position on one side wall of the side wall 1 as an elongated hole in the length direction to uniformly discharge water, and a water outlet installed in contact with the inner wall of the water supply tank 41 so as to be vertically movable. A gate valve 43 for opening and closing 42; a flow guide 48 installed below the front side of the water discharge port 42 to guide the discharged water gently to the outer peripheral surface of the cooling drum 21; A discharge pipe 45 installed at a position higher than the water discharge port 42 to discharge water to the outside when the level of the water supplied to the water supply tank 41 becomes a certain level or higher,
The water supply tank 41 includes a drain pipe 46 connected to a predetermined position on the bottom of the water supply tank 41, and a drain valve 47 installed on a pipe of the drain pipe.

The water supplied through the water supply pipe 44 is supplied to the inside of the water supply tank 41 so that the supplied water is discharged to the outside via the discharge pipe 45 when the supplied water exceeds a predetermined amount. Therefore, a certain amount of water is stored in the water supply tank 41 so that the surface of the water is higher than the height of the water outlet 42. Thereafter, when the cooling drum 21 is sufficiently cooled and rotated, the gate valve 43 moves upward by manual operation or automatic means, and water flows out through the water discharge port 42. At this time, since the depth of the water contained in the water supply tank 41 is always kept higher than the water outlet 42,
Even if the apparatus is tilted, the amount of water discharged through the discharge port 42 becomes constant, and is uniformly discharged along the length direction. Thereafter, the water discharged from the water outlet 42 is
Flows slowly on the guide surface of the flow guide unit 48 installed under the front side of the cooling drum 21 and uniformly adheres to the outer peripheral surface of the rotating cooling drum 21. Water adhering to the outer peripheral surface of the cooling drum 21 is rapidly frozen to form an ice layer, and the ice layer is scraped off by the ice-sharpening blade 29 similarly to the devices of the first and second embodiments.

When cleaning the water supply tank 41,
By opening the drain valve 47 and discharging the water from the drain pipe 46 while continuously supplying water through the water supply pipe 44, it is possible to efficiently clean the water without taking out the water supply means to the outside.

According to the device of the third embodiment configured as described above, the following effects can be achieved in addition to the effects described in the first and second embodiments.

Since a water supply tank capable of storing a large amount of water is provided, it can be applied to a shaved ice producing apparatus having a large capacity. In other words, the water supply tank holds a large amount of water, and the amount of water attached to the cooling drum can be adjusted by the degree of opening and closing of the gate valve. It is possible to appropriately cope with a case where the rotation speed of the drum is high to obtain a layer.

Further, since the drain means is provided on the bottom surface of the water supply tank, it is easy to remove the contaminants and to discharge the stagnant water, so that the shaved ice producing apparatus can be managed more hygienically. .

The discharge pipe connected to the side surface of the water supply tank at a predetermined height position has a function of keeping the level of the water supplied to the water supply tank constant and easily discharging foreign substances floating in the water. Also fulfills.

Further, since the gate valve of the water supply tank is located below the surface of the water contained therein, even when the apparatus is placed at a slight angle, water always flows out to the cooling drum in a uniform amount. Thereby, an ice layer is uniformly formed on the outer peripheral surface of the cooling drum.

Next, a fourth embodiment of the present invention will be described with reference to FIGS. In the following description of the fourth embodiment, points different from the first to third embodiments will be mainly described, but the first to third embodiments will be mainly described.

At a predetermined position inside the water supply tank 51, a water level sensing means 54a for sensing the water level of the water is installed, and a control unit for controlling the electronic valve 54 by a control signal based on a sensing signal from the water level sensing means 54a. (Not shown).

Further, in the apparatus of the fourth embodiment, as shown in FIG. 9, the ice-cutting blade 29 is installed horizontally on the center line of the cooling drum 21. The end of the ice-cutting blade 29 has an inclined surface 29a as shown in the figure, and the inclined surface 29a faces upward, and the tip is installed so as to be in vertical contact with the outer peripheral surface of the cooling drum 21. You. Therefore, the inclined surface 29a

At this time, the water continuously flows down by a predetermined amount from the discharge means 53, spreads quickly and widely and uniformly in a narrow space formed by the inclined surface 29a and the cooling drum 21. Thereafter, the uniformly distributed water is sufficiently cooled, adheres to the outer peripheral surface of the cooling drum 21 rotating clockwise, and rapidly freezes. Since water is supplied from the discharge means 53 and adhesion and freezing of the supplied water are continuously performed on the outer peripheral surface of the cooling drum, a thin and uniform ice layer is formed on the outer peripheral surface of the rotating drum 21. Thereafter, the ice layer formed on the cooling drum 21 rotates together with the cooling drum 21 to rotate the ice

That is, the amount of water supplied via the discharge means 53 is adjusted by the pressure of the water contained in the water supply tank 51 itself. After selecting the desired amount of shaved ice and the thickness of the ice layer, the control unit (not shown) sets an appropriate rotation speed of the cooling drum 21 correspondingly, and sets an appropriate amount of water through the discharging means 53. In order to supply water, the amount of water stored in the water supply tank 51 is set, and a control signal is sent to the electronic valve 54 to open the valve. By opening the electronic valve 54, the water is supplied into the water supply tank 51 through the water supply pipe 52 until the water reaches the set amount. At this time, the water level sensing means 54a installed in the water supply tank 51 senses the level of the supplied water and sends a sensing signal to the controller,
When the set water level is reached, the control unit sends a valve shutoff signal to the electronic valve 54 to shut off the water supply. afterwards,
An appropriate amount of water is discharged toward the cooling drum 21 via the discharging means 53 by the pressure of the water itself stored in the water supply tank 51. Thereafter, when the water is discharged from the water supply tank 51, the lowered water surface in the water supply tank 51 is sensed by the water surface sensing means 54a, and the electronic valve 54 is opened by a control signal based on this sensing signal, and the reduced water amount The amount of water corresponding to is refilled. Thus, the water surface sensing means 5
4a, water supply tank 51 by electronic valve 54 and control unit
The water level at is always maintained at the set level.
Since the amount of water contained in the water supply tank 51 is always constant and the water pressure is thereby kept constant, the amount of water supplied to the cooling drum 21 via the discharge means 53 is always constant, and as a result, An ice layer is formed on the outer peripheral surface of the cooling drum.

The device of the fourth embodiment achieves the following additional effects in addition to the effects of the devices of the first to third embodiments.

First, a constant amount of water is continuously supplied through the discharge means by the pressure of the water maintained constant in the water supply tank, and the supplied water is supplied to the inclined surface of the ice-cutting blade and the drum. Since water is uniformly distributed in the space formed by the outer peripheral surface, the water adheres to the outer peripheral surface of the rotating drum uniformly and freezes, so that a more uniform ice layer can be obtained.

Further, since a plurality of discharge means are formed on the bottom surface of the water supply tank, when the water supply tank needs to be cleaned, the discharge means is used to discharge the waste water after cleaning the water supply tank. The water supply means can be easily cleaned.

Further, since the ice-cutting blade is installed horizontally on the center line of the cooling drum so that the tip end of the ice-cutting blade is in vertical contact with the outer peripheral surface of the cooling drum, the tip of the ice-cutting blade is As a result, the outer peripheral surface of the cooling drum is not damaged by the tip of the ice-cutting blade, and the tip of the ice-cutting blade itself can be prevented from being damaged. Further, since a concave portion having a gentle inclined surface at a predetermined angle is formed on the lower surface of the end portion of the ice-cutting blade, the scraped ice layer moves along the inclined surface of the concave portion to a predetermined size. , And as a result, ice particles of a uniform size can be obtained.

Incidentally, an opening / closing valve (not shown) may be provided in the discharging means 53 in order to prevent the water from being discharged through the discharging means 53. By providing the opening / closing valve, the water discharged from the discharging means 53 can be shut off when the shaved ice making device is not used or when the cooling drum is rotated without supplying water for maintenance. Of course, the water is supplied by opening the opening / closing valve when the shaved ice producing apparatus is operated.

Further, a water supply pump (not shown) may be provided in a water supply pipe 52 between an external water supply means (not shown) such as a water purification bottle and an electronic valve 54. By using the water supply pump, water can be smoothly supplied to the water supply tank 51 irrespective of the installation position of the external water supply means.

Further, in addition to the water supply pump, a sealed water supply tank may be provided, and an injection nozzle (not shown) may be attached as a discharging means of the sealed water supply tank. In this case, the water pressurized by the water supply pump is supplied to the sealed water supply tank via the electronic valve 54, and the injection nozzle of the water supply tank uses the water pressure in the water supply tank 51 to supply water. Injection is made evenly by the cooling drum 21. At this time, pressure sensing means is installed in the sealed water supply tank, and the electronic valve 54 is opened and closed based on a signal detected by the pressure sensing means to supply pressurized water to the sealed water supply tank. Then, the pressure of the water in the water supply tank is kept constant. As a result, the water sprayed between the inclined surface 29a of the ice cutting blade 29 and the outer peripheral surface of the cooling drum is uniformly distributed on the outer peripheral surface of the cooling drum, and a more uniform ice layer is formed on the outer peripheral surface of the cooling drum 21. Is done. Further, the thickness of the ice formed on the outer peripheral surface of the cooling drum can be adjusted by the amount of water injected by the water pressure in the water supply tank, and the pressure of the water is determined by a pressure sensing means installed in the water supply tank. Is determined by the set value of the control valve and the control valve linked thereto by the control signal.

Further, the water supply means according to the fourth embodiment may include means for moving the water supply tank in order to adjust the water supply position.

Next, an apparatus according to a fifth embodiment of the present invention will be described with reference to FIGS. FIG. 11 is a schematic diagram showing a shaved ice producing apparatus according to a fifth embodiment of the present invention, and FIG. 12 is a schematic diagram showing a state in which the positions of the ice-cutting blade and the nozzle in FIG. 11 have been changed. FIG. 13 is a schematic view of an embodiment in which the side auxiliary blades are installed on both sides of the cooling drum, and FIG. 14 is a front view and a side view illustrating the side auxiliary blades. As shown, the apparatus of the fifth embodiment is different from the first to fourth embodiments except that water is directly supplied between the cooling drum and the ice-cutting blade via a supply pipe.
It has the same configuration and operation as in the embodiment. Therefore,
In the following description, differences from the first to fourth embodiments will be mainly described, and the same or similar components will be denoted by the same reference characters and detailed description thereof will be omitted.

The apparatus according to the fifth embodiment supplies water from an external water supply source (not shown) directly to a cooling drum via a supply pipe to form an ice layer. In this point, the third embodiment is different from the first to fourth embodiments. In other words, according to the device of the fifth embodiment,
A water supply tank and a water supply suit as intermediate water supply means as shown in the first to fourth embodiments are omitted. According to the apparatus of the fifth embodiment, the tangential line of the cooling drum is used in order to effectively attach the supplied water to the cooling drum and freeze the ice, and to efficiently scrape the ice layer formed on the surface of the cooling drum. An ice-cutting blade is installed in the direction.

As shown in the figure, the shaved ice manufacturing apparatus according to the fifth embodiment is a rotating cylindrical drum, a cooling drum 21 for adhering water to the outer peripheral surface and freezing it,
A water supply pipe 5 extending from an external water supply source to a predetermined position above the cooling drum 21 and supplying water to the cooling drum 21
2 and a cooling drum 2 by pressurizing water from an external water supply source.
A water supply pump 55 installed on the pipe of the water supply pipe 52 to supply the water to the water supply pipe 1 and a water supply pipe 52 are installed at an end of the water supply pipe 52 on the side of the cooling drum 21 so that the discharge angle can be adjusted, and pressurized water And a water supply pipe 52 between the water supply pump 55 and the nozzle 53 for appropriately adjusting the flow rate of the water pressurized by the water supply pump 55 and supplying the water to the nozzle 53. The cooling valve 21 is disposed so that one end thereof is in contact with an outer peripheral surface on a horizontal center line of the cooling drum 21 in order to scrape an ice layer formed on the outer peripheral surface of the cooling drum 21. An ice-cutting blade 29 whose angle is adjustable between the center line and a vertical tangent line that is in contact with the outer peripheral surface, and an unnecessary ice layer frozen on both sides of the cooling drum 21 is scraped and removed. , Cooling drum 21 Constructed from the side auxiliary cutting edge 59 disposed in a position close to both sides (Figure 13). Here, as shown in the figure, the end of the nozzle 53 is
It is preferable that the water supply pipe 52 be attached to one end of the water supply pipe 52 at a predetermined angle with respect to the vertical line so as to face the vertical direction. Also,
As shown in FIG.
Of a predetermined angle on the surface opposite to the side in contact with the outer peripheral surface of
9a is formed, and a gentle curved curved groove 29b is formed in the inclined surface 29a in the lateral direction of the ice-cutting blade 29.

The operation of the fifth embodiment of the present invention will be described below with reference to FIGS. When power is supplied to the shaved ice making apparatus (when the power switch is ON), the temperature of the cooling drum 21 falls below the freezing point by the operation of the refrigerant compressor while the cooling drum 21 rotates. Cooling drum 21
When the water is cooled to a temperature below the freezing point, the water supply pump 55 is operated to pressurize and supply water from an external water supply source, and the pressurized water is adjusted to an appropriate pressure by the adjustment valve 54. The water is supplied to a nozzle 53 provided at the end of the water supply pipe 52. In order for the water adhering to the cooling drum 21 to have a sufficient freezing time, the water adjusted to an appropriate pressure and discharged through the nozzle 53 is discharged between the cooling drum 21 and the ice-sharpening blade 29 (sharpening). 11 is supplied to the outer peripheral surface of the cooling drum 21 and freezes.
During the rotation of the cooling drum 21 in the rotation direction (counterclockwise) indicated by the arrow, an ice layer having a predetermined thickness is formed on the outer peripheral surface of the cooling drum 21. The ice layer that rotates together with the cooling drum 21 is scraped out by an ice-sharpening blade 29 installed so that one end thereof is in contact with the drum, falls downward, and is stored in the storage container 30.

Here, the thickness of the ice layer formed on the outer peripheral surface of the cooling drum 21 and the quality of the ice are controlled by the control valve 54, the rotation speed of the cooling drum 21,
And the ice-cutting blade 29 appropriately adjusts the spray angle.
That is, when the user wants to obtain thick and hard ice, the rotational speed of the cooling drum 21 is reduced.
1 increase the rotation speed. Here, the speed of the cooling drum 21 is adjusted by a speed adjusting knob (KNOB) installed inside the drum. Further, the thickness of the ice layer can be adjusted by adjusting the adjustment valve 54 to adjust the amount of water discharged through the nozzle 53. That is, for example, when the amount of water to be discharged is reduced and the rotation speed of the cooling drum is reduced, hard fine ice is obtained. On the other hand, when the amount of water to be discharged is increased and the rotation speed of the cooling drum is reduced, hard coarse ice is obtained. Is obtained. When the amount of supplied water is reduced and the rotation speed of the cooling drum is increased, soft fine ice is obtained. When the amount of water is increased and the rotation speed of the cooling drum is increased, soft coarse ice is obtained. Further, according to the device of the fifth embodiment, the direction of discharging water from the nozzle 53 can be adjusted. However, the quality of ice can also be changed depending on the position at which the nozzle 53 discharges. That is, the sprayed water is sprayed so as to directly touch the cooling drum 21 or sprayed between the cooling drum 21 and the ice-cutting blade 29, so that the water adhering to the cooling drum comes into contact during rotation. By adjusting the time, the ice can be hardened or softened. In other words, if water is sprayed between the cooling drum 21 and the ice-cutting blade 29 with a slight inclination toward the ice-cutting blade, ice having appropriate strength is obtained during one rotation of the cooling drum. As a result, when the jetting direction of the nozzle 53 is adjusted toward the cooling drum 21 to reduce the contact time between water adhering to the cooling drum 21 and the cooling drum, ice having soft ice quality can be obtained. .

According to the device of the fifth embodiment, the ice-sharpening blade 29
Is installed so as to be adjustable from a vertical position as shown in FIG. 11 to a horizontal position as shown in FIG. 12, so that when the angle of the ice-breaking blade is at the vertical position, coarse ice is obtained, and Fine ice is obtained when in the horizontal position. In addition, ice-sharpening blade 29
By appropriately adjusting the angle, the shaking development of the ice-cutting blade 29 itself can also be prevented. That is, when coarse ice is obtained from the cooling drum 21, a strong force acts on the contact end portion between the ice cutting blade 29 and the cooling drum 21, and the ice cutting blade 29 supported at one end vibrates. The efficiency of the apparatus may be reduced, and the cooling drum may be damaged by the blade edge due to the vibration of the ice-cutting blade 29. Therefore, it is preferable that the angle of the ice-cutting blade 29 be set closer to the vertical position in the tangential direction as the ice to be obtained is coarser and harder. Further, since the curved groove 29b is formed on the inclined surface 29a of the ice-sharpening blade 29, the size of the obtained ice is also adjusted by this. That is, when the size or the curvature of the curved groove 29b is changed, the length of cutting of the ice layer in which the ice scraped from the cooling drum 21 moves along the inclined curved surface of the curved groove 29b is changed.
Therefore, the size of ice can be adjusted by the cutting length according to the curved groove 29b.

In the apparatus of the fifth embodiment, as in the other embodiments, the auxiliary blades 59 are provided on both sides of the cooling drum 21 to remove ice layers frozen on both sides of the cooling drum. Can be. As shown in FIG. 14, the auxiliary blades 59 on the side surfaces are rhombic blades having blades formed on both side surfaces of a predetermined length, and the supporting portions 210 on both sides for supporting the rotating shaft of the cooling drum and the cooling drum The bracket 21 is supported by the support portion 210 via the bracket 60 so as to be located between both side surfaces of the bracket 21. Therefore, it is possible to prevent ice formed between the support portion and both side surfaces of the cooling drum from hindering rotation of the drum, which is also desirable in terms of hygiene.

The present invention described above can be variously replaced, modified and changed without departing from the technical idea of the present invention without being limited by the above-described embodiment and the accompanying drawings.
