Description

Electric Ice Machine {Apparatus for shaving Ice}

The present invention relates to an ice machine, and in particular, by improving the structure of the wheel that rotates the ice introduced into the ice chamber, to increase the ice efficiency of the ice, and to simplify the disassembly and assembly of the wheel, thereby improving the convenience of washing. Attached to one side of the overheat preventing means relates to an electric ice machine that doubles the life of the motor by automatically shutting off the power supplied to the motor when the motor overheats.

The ice grinder, which is generally used, is rotated while applying pressure to the ice vertically to be iced by a blade mounted on the bottom surface, and the ice is rotated by a wheel (rotary body) that is rotated in the ice chamber. It is known that a revolutionary ice cutting method to make the ice to be rotated by the blade mounted in the ice chamber, the present invention is to improve the shortcomings of the ice machine adopting the idler ice cutting method of the above-mentioned ice cutting method.

1 and 2 show an example of a conventional ice machine, FIG. 1A is an external perspective view of an ice machine, FIG. 1B is a partial sectional view showing an inner main portion of the ice machine, and FIG. 2 is a view of a wheel.

As shown in the figure, the lower housing 30 is mounted on the upper end of the base 10 at the bottom of the ice machine, and the upper housing 50 is fixed on the upper side of the lower housing by fixing means such as bolts. The base 10 is provided with a drain container 20, the lower housing 30 is formed in the front and lower portion of the ice water container space 49, the upper housing 50 is the opening (opening and closing by the lid 71) ( 73 is formed on the upper surface.

Inside the upper and lower housings 30 and 50, an ice cutting chamber 51 is incorporated as shown in FIG. 1B. Inside the lower housing 30, an ice cutting chamber 51, which is an inclined surface of the upper and lower straits, is provided with a discharge pipe 57 on the inclined surface, and a support frame 35 is mounted on the lower side thereof. In the center of the support frame 35, the rotating shaft 37 is mandrel provided by the bearings 148 and 39 so that both ends are exposed to the inside of the ice cutting chamber 51 and the bottom of the support frame 35. The wheel 60 is fixed to the upper end of the rotating shaft 37 by fixing means 55 such as a bolt, and a pulley 33-3 is fixed to the lower end of the rotary shaft 37. The pulley 33-3 is a belt. (33-2) is connected to the pulley (33-1) fixed to the shaft of the motor (31), and the upper side of the upper housing (50) so as to communicate with the ice cutting chamber (51) I) The ice chamber cover 80 is attached, and the protection cap 75 is covered on the outside of the ice chamber cover 80.

The conventional ice machine configured as described above has various problems. When the wheel 60 provided in the ice cutting chamber 51 rotates the ice in the ice cutting chamber 51 as shown in FIG. 2, the wheel blade 65 is iced. Since it is made of a simple flat bar shape for rotating the ice as it rises toward the cover 80 by the centrifugal force of the ice during ice reduction is significantly reduced. That is, since the ice rises to the cover 80 side by the centrifugal force when the wheel 60 rotates, the ice cutting efficiency is lowered since the ice cutting blade 59 is installed in the ice cutting chamber 51.

In addition, the conventional ice machine needs a separate tool for loosening and tightening the bolt 55 when dismantling the ice chamber cover 80 and disassembling and combining the wheel 60, and thus, the wheel 60 is not easily disassembled. There are problems such as not easy cleaning of the room, shortening the life of the motor due to the overload of the rotary motor.

That is, the conventional ice machine needs to separate the ice chamber cover 80 from the upper housing 50 as shown in FIGS. 1B and 2, and the protective cap 75, the ice chamber cover 80, and the ice chamber The protection cap 75 can be separated from the annular frame 85 of the ice chamber cover 80 by releasing the bolt 79, which fastens the 51 to each other, from the annular frame 85. When the ice chamber cover 80 is not easily removed from the 51 and the ice chamber cover 80 is attempted to be separated by an excessive force in the coupled state, the ice chamber cover 80 is damaged.

In addition, the wheel 60 is coupled to the rotating shaft 37 by a roll method, which is an uneven groove 62 and the rotating shaft 37 formed at the center of the fixing plate 61 having the wings 65 at equal intervals. Since the bolts 55 are coupled to the nut hole 45 and the bolt insertion hole 64 after the uneven bars 43 of the support plate 41 of the support plate are interfitted with each other, the bolt 55 is released only once. There could be a significant difficulty in separating the uneven bar 43 and the uneven groove 62 is inserted.

As described above, the conventional ice machine is not easy to disassemble and disassemble the cover 80 and the wheel 60 of the ice chamber, and thus it is difficult to clean the ice chamber. The simple flat structure of the wheel makes the ice ice efficiency very low. There are various problems such as shortening the life of the motor due to overheating of the motor in continuous use.

Accordingly, it is an object of the present invention to improve the structure of the wheel for rotating the ice injected into the ice chamber to provide an electric ice machine that can increase the ice efficiency to the maximum by closely adhering the ice to the ice blade side during the wheel rotation.

Another object of the present invention is to provide an electric ice machine which can be maintained hygienically and always cleanly by improving the convenience of disassembling and assembling the wheel installed in the ice chamber and improving the cleaning convenience of the ice cube room.

Another object of the present invention is to provide an electric ice machine which can receive ice powder more efficiently by forming a concave so that the ice-cold container is completely in contact with the ice-cold container space from which the ice powder iced from the ice-cream chamber is discharged. .

Still another object of the present invention is to provide an electric ice machine which doubles the life and stability of the ice machine by configuring a power transmission means for transmitting the rotational power of the motor to the wheel side with a multi-stage reduction gear.

Figure 3 is a perspective view showing the appearance of the electric ice machine according to the present invention, Figure 4 is a cross-sectional view showing the main portion of Figure 3 according to an embodiment of the present invention.

In the ice machine 100 according to the present invention, as shown in FIGS. 3 and 4, the lower housing 130 is fixedly installed on the upper side of the base 110, and fastened like a bolt to the upper side of the lower housing 130. The upper housing 150 is simply fixed and installed by a fitting rotation method instead of a means, and an ice chamber cover 180 is coupled to an upper end of the upper housing 150.

The outer side of the upper housing 150, that is, one side of the discharge port for discharging the ice powder to the outside is equipped with a bin blade 151, the handle 152 of the bin blade 151 rotates left or right If the blade is made of a structure that rises or descends inside the ice cutting chamber (155). Accordingly, the thickness of the ice powder to be shaved can be arbitrarily adjusted by the user by turning the handle 152 to the left or the right.

In addition, the base 110 and the lower housing 130 are provided with a shaved ice container space 115, which is slightly recessed in a bow shape when viewed from the front, which sets the shaved ice bucket (shaved ice bowl) on this portion. By fully adhering to the cylinder space part 115, it is for storing the ice powder cut out from the ice cutting blade provided in the side surface of the ice cutting chamber 155 more efficiently.

On / off power switch 135 is installed on the outside of the lower housing 130, and there is a motor 140 made of a coil, an iron core, a magnet and a rotor as shown in FIG. The bobbin has a built-in overheat temperature preventing means (120). Therefore, as the power switch 135 is turned on, power is supplied to the coil side to rotate the motor 140, and power transmission means 143-1 to 143-3 such as a multistage reduction gear according to the rotation of the motor 140. The rotating shaft 145 is rotated through).

In addition, the wheel 160 embedded in the ice chamber 155 of the upper housing 150 is coupled to the rotation shaft 145 to rotate the ice introduced into the ice chamber 155 according to the rotation of the rotation shaft 145. Ice is shaved by an ice cutting blade (not shown) fixed to the side of the ice cutting chamber 155.

In addition, the ice cutting chamber 155 provided inside the upper housing 150 has a shape of a fallopian tube of the upper and lower narrowings, and in the lower center of the ice cutting chamber 155, a rotating shaft 145 such as a female screw freely rotated by the bearing 148. ) Is installed vertically mandrel is exposed to the ice chamber 155, the leakage around the rotating shaft 145 exposed to the ice chamber 155 to prevent the ice ice ice leaks on the rotating shaft 145 It is equipped with a prevention oil seal 147, and the wheel 160, which will be described in detail later, is mounted on the top of the rotating shaft 145, and the gear housing 143 is located at the bottom thereof. Power is transmitted from the motor 140 through 1 to 143-3. Unexplained reference numeral 143-4 is a bushing like a ball bearing for preventing leakage, and reference numeral 143-5 is a column for preventing the departure of the gear 143-3.

The gear 143-3 located at the lower end of the rotating shaft 145 is connected to the reduction gear 143-1 fixed to the shaft 141 of the motor 140 by the turning gear 143-2, The motor 140 is provided with an overheat prevention means 120 to open and close the power supplied to the coil side of the motor 140 according to the overheating temperature of the motor 140. The overheat preventing means 120 is preferably installed in series between the power plug 101 and the coil of the motor 140 as a thermistor projector whose resistance value changes with temperature.

On the other hand, the upper side of the ice chamber 155 is formed to be freely detachable without a separate fastening means, such as screws, the ice chamber cover 180 having the shape of the upper and lower light is push button 191 and the locking step 195 Removable to the upper housing 150 using the).

Figure 5 is an exploded and assembled perspective view of the wheel, Figure 5a shows a coupling structure of the wheel and the rotating shaft, Figure 5b is a bottom view of the wheel.

The rotating shaft 145 is composed of a rotating rod formed with a nut 146, such as a female screw slightly exposed upward from the bottom center of the ice chamber 155, the wheel 160 is a male screw on the bottom surface of the central support surface 161; The same bolt 163 is inserted to rotate the bolt 163 of the wheel 160 to the nut hole 146 of the rotating shaft 145 to be inserted.

That is, unlike the prior art by having a configuration that requires no separate fastening means for coupling the rotary shaft 145 and the wheel 160 at all, by turning the wheel 160 in a predetermined direction the rotary shaft 145 ) Is combined.

In addition, the wheel 160 has an inverted conical structure that is matched with a fallopian tube-shaped ice chamber 155, and a plurality of wheel blades 165 are formed at equal intervals (120 °) in the circumferential direction from the central support surface 161. At the top of each wheel blade 165, a circular frame-shaped wheel blade assembly 167 is enclosed so that a plurality of wheel blades 165 are fixed to each other.

In addition, a cylindrical wheel cover 169 is covered by a fastening means such as a screw on the upper side of the wheel blade assembly 167 formed on the top of the wheel 160, the wheel cover 169 is flanged on one side (169-) 1) the cylindrical flange (169-1) in close contact with the upper end of the wheel blade assembly 167 is completely coupled to the coupling means such as screws.

The wheel blade 165 is installed at a slightly twisted angle with respect to the central ground surface 161, which more efficiently transmits the force applied to the ice during rotation of the wheel 160, and the ice floats due to the centrifugal force. Consists of a structure that prevents the operation to improve the ice cutting efficiency per unit time.

In addition, by additionally forming a circular-rim wheel assembly 167 on the top of the wheel blade 165, the ice is prevented from rising to the cover 169 side by centrifugal force to further increase the ice cutting efficiency of the ice.

The wheel blade 165 is slightly curved in the xyz axis direction with respect to the center support surface 161 when the -x axis is rotated on the xyz axis, and the lower blade 165-2 in contact with the ice cutting blade is the upper blade ( Much more curved than in 165-1). That is, the wheel blade 165 is slightly curved in a direction opposite to the direction in which the wheel blade 165 rotates, and the lower wheel blade 165-2 is slightly twisted to the rear than the upper wheel blade 165-1.

Therefore, the wheel blade 165 is different in width and thickness from the first portion 165-3 in contact with the central support surface 161 and the second portion 165-4 in contact with the wheel blade assembly 167 which is a ring-shaped rim. The width of the second portion 165-4 is wider than the width of the first portion 165-3, and the thickness of the second portion 165-4 is somewhat thinner than the thickness of the first portion 165-3. .

Due to the structure, the wheel 160 rotates the ice more strongly to the ice cutting blade side, and also increases the friction between the ice and the ice cutting blade to improve the ice grinding ability.

Hereinafter, the operation of the ice machine configured as described above will be described.

With the plug 101 of the ice machine inserted into an outlet (not shown) so as to supply power to the motor 140, the lid 181 of the ice cutting chamber cover 180 is flipped open to open the inlet 185. Through the inlet 185 is put into a piece of crushed or crushed ice. The injected ice cubes are filled in the ice chamber 155, and after filling the appropriate amount, the lid 181 is returned to its original state to close the inlet 185.

When the operation switch 135 is turned on in a state in which a container is placed on the lower side of the discharge pipe, that is, in the ice water container space 115 to hold ice ice, the motor 140 is operated by supplying power to the motor 140. The deceleration gear 143-1 of the power transmission means 143 is rotated by the operation of the motor 140, and is connected by the turning gear 143-2 by the rotation of the reduction gear 143-1. Since the gear 143-3 also rotates, the wheel 160 rotates together with the rotation shaft 145.

When the wheel 160 is rotated, the ice pieces filled in the ice chamber 155 are forced to move and rotate by the wheel blades 165, and thus the ice pieces that move and rotate move the blades of the blade bundle 151. As it passes through, it is iced sequentially, and the iced ice powder is discharged outward through the outlet to fill the container.

As such, when the ice pieces are iced by the blade, the handle 152 can be turned to adjust the height (thickness) of the ice by adjusting the height of the blade. That is, when the handle 152 is rotated forward / reversely, the height of the blade is adjusted as the blade is inserted / deleted into the ice chamber 155 to adjust the thickness of the ice powder. Thus, by adjusting the height of the blade by the operation of the handle 152, it is possible to adjust the thickness of the ice iced.

In particular, due to the structure that the lower wheel blade 165-2 is twisted more rearward than the wheel blade 165 and the upper wheel blade 165-1 that are bent backward when ice cutting is performed, the friction force applied to the ice cutting blade side of the ice piece increases. As a result, the ice cutting efficiency per unit time is quite excellent.

Thereafter, when the ice cutting is completed, the operation switch 135 is turned off to stop the operation of the ice machine.

On the other hand, if an overload occurs in the motor 140 during continuous operation of the ice machine, the overheat prevention means 120 installed on the motor 140 detects this and automatically cuts off the power supplied to the motor 140. By doing so, it is possible to prevent damage and shortening of the life of the motor 140 due to the overload.

In addition, the bolt 163 such as a male screw formed at the bottom of the center support surface 161 of the wheel 160 may be detachably rotated to the nut hole 146 of the rotation shaft 145 to the left or the right, without a separate tool and procedure. Disassembly and assembly of the wheel 160 can be performed in a simple manner, thereby making it easy to clean the wheel 160 and the ice chamber 155 of the ice machine.

Of course, the ice chamber cover 180 can be easily detached from the upper housing 150 without a separate coupling means, when cleaning the interior of the ice chamber 155, in particular, be careful not to cut your hands by the blade , It is safe to rotate the handle 152 in the state in which the blade is retracted outside the ice chamber 155.

Although specific embodiments of the present invention have been described and illustrated above, it is obvious that the appearance and location of the ice-breaking mechanism of the present invention may be variously modified and implemented by those skilled in the art. Such a simple structure change should not be understood individually from the technical idea or the prospect of the present invention, and such modified embodiments should fall within the claims appended to the present invention.

Therefore, the present invention improves the structure of the wheel for rotating the ice introduced into the ice chamber to maximize the friction force by maximizing the friction force to the ice closer to the ice blade side when the wheel rotates, to maximize the ice efficiency and installed in the ice chamber By disassembling and assembling the wheel more easily, there is an advantage that the hygienic convenience can be always maintained cleanly.

In addition, by forming the front ice water container space portion in which the ice powder iced in the ice chamber is discharged so as to be in close contact with the ice water container, the ice powder can be received more efficiently, and power transmission for transmitting the rotational power of the motor to the wheel side. By constructing the means not as a pulley but as a multistage reduction gear, there is an effect of further improving the life and stability of the ice machine.
