As shown in FIGS. 1A and 1B, the inventive ice-maker also scrapes ice formed on the outer peripheral surface of the ice-making drum through the blade 4 while the ice-making drum 1 is in contact with the raw water of the ice-making water tank 2 The basic configuration is a powder ice ice maker.

The cooling cycle unit A supplies the inside of the ice-making drum 1 with a coolant to cool the outer peripheral surface of the ice-making drum 1. The cooling cycle unit A rotates the raw material water contacting the outer circumferential surface of the ice-making drum 1, and forms ice (I) on its surface.

The cooling cycle unit A includes a compressor A1, a condenser A2, an expansion unit A3, and an evaporator A4. The compressor (A1) compresses the refrigerant and can compress the refrigerant discharged from the ice-making drum (1) at a low temperature and a low pressure into a high-temperature and high-pressure gas state.

In the condenser A2, the refrigerant compressed through the compressor A1 is condensed, and the refrigerant compressed in the high-temperature and high-pressure gas state can be condensed into a liquid state.

The expanding portion A3 expands the refrigerant condensed through the condenser A2 and supplies it to evaporate in the ice-making drum 1. The expansion part A3 expands the liquid refrigerant into a low-temperature and low-pressure gas state by condensation and supplies it to the inside of the ice-making drum 1. At this time, a nozzle for spraying the coolant and a pipe type evaporator A4 may be installed inside the ice-making drum 1 to reach the nozzle.

FIGS. 7A, 7B, and 7C are sectional views of the passage portion of the tube portion of the powder ice ice- FIG.

4 to 8, the raw water supply portion 3 is divided into a raw water tank 30, a control rod 31, and an assembly tube body 32.

That is, the raw water supply portion 3 constitutes a raw water storage raw water tank 30 which is covered with a lid 308 of a predetermined shape. On the bottom side of the raw water storage tank 30, .

The raw water tank 30 is composed of a water receiving portion 301 forming a raw water receiving space and a tubular portion 302 extending from the tub 301. The tub 301 and the tubular portion 302 ) Can be formed in a single form, so that when detached, the detachable unit can be detached integrally.

The tubular part 302 forms a flow path on the pipe, forms a wider inlet at the inlet side thereof, and forms a first placement part 306. At a lower position of the first placement part 306, the diameter of the tubular part is narrowed and the second placement part 307 And a first flow path 303 is formed along a central portion of the first and second placement units 306 and 307.

5B, the internal flow path of the tubular portion 302 is formed in the tubular portion 302 so as to have a height along the inner circumferential surface of the bottom-side first flow path 303 of the raw water bath 30, The first wafers 306 and the second wafers 307 are formed to be different from each other and the second flow path 305 narrowed at the lower end of the tubular portion 302 is formed. The spiral portion 304 can be formed on the outer circumferential surface of the second flow path 305.

Particularly, as shown in Fig. 6, the tubular portion 302 is preferably of the assembled type in which the valve seat 321 is screwed to the lower end thereof.

That is, the tubular body 302 may be provided with the assembly tube body 32 assembled at the lower end thereof by screwing. The assembly tube 32 is opened upward and a spiral portion 323 is formed inside the spiral tube 32. The diameter of the spiral portion 323 is narrowed at the lower end of the assembly tube 32 to form a flow passage hole 322 penetrating the second flow passage 305. Particularly, as shown in FIGS. 7a, 7b and 7c, the assembly tube body 32 can be realized by the assembly tube body 32 having diameters (a, b, c) according to the number of raw materials. In this assembly tube 32, the spiral portion 323 may correspond to the spiral portion 304 of the tubular body portion 302 and may be assembled and coupled by screwing.

In particular, the configuration of the tubular body portion 302 and the assembly tube body 32 can form an integral valve seat (not shown) without the spiral portions 304 and 323 instead of such an assembled structure. At this time, the valve seat 321 in which the flow passage hole 322 is formed below the first and second flow paths 303 and 305 of the raw material water tank 30 is integrally formed with the valve seat 321 without the spiral portions 304 and 323 .

8, the design control rod 31 forms a relatively narrow second gap-maintaining portion 317 in a predetermined lower longitudinal section of the central valve stem 312, A first interval holding portion 316 is formed relatively wide in a predetermined section of the middle portion in the direction of the first interval holding portion 316 and a latching portion 314 is formed at a predetermined position of the second interval holding portion 316 in a lateral direction. An opening / closing valve 311 is formed at the lower end of the valve stem 312, and a handle 315 is provided at an upper end of the valve stem 312 to allow the user to grasp the stem.

The control rod 31 has a first gap holding portion 316 on the first flow path 303 of the tubular portion 302 and a second gap holding portion 317 on the second flow path 305 Thereby forming a supply flow path for the raw water. That is, a certain section of the second interval maintaining section 317 is provided so as to correspond to the second flow path 305 of the tubular section 302, and the first interval maintaining section 316, It can be installed in the first flow path 303 of the pipe diameter. The first and second gap holders 316 and 317 can be adjusted by adjusting the width of the control rod 31 in order to supply the channel with the stable upper and lower heights.

Particularly, the engagement portion 314 may be formed at a predetermined position of the first interval holding portion 316 of the control rod 31 so as to be longer than the first interval holding portion 316. This realizes a fluid-free operation in the vertical rotation operation of the control rod (31). That is, when the grip portion 315 formed at the upper end is rotated in the perpendicular direction, the control rod 31 is placed on the first placement portion 306 or the second placement portion 307, and at the same time, It is possible to open and close the flow passage hole 322 since the position can be moved upward and downward without flowing.

As shown in FIG. 8, the latching portion 314 is caught and placed in the first placement portion 306 of the tubular body portion 302, but may be positioned at the second placement portion 307 by turning at right angles. The rotation stopping operation of the latching portion 314 raises the height of the control rod 31 by a predetermined distance a, and the lower flow passage hole 322 can be opened or closed according to the lowering.

Accordingly, the latching portion 314 is formed on both sides in the horizontal direction in the middle portion of the valve stem 312 and selectively placed on the first and second placement portions 306 and 307, 322) can be opened and closed.

One of the features of the inventive powder ice ice maker is that although it is possible to vary the diameter of the flow passage hole 322 of the assembly tube 32 as shown in Figures 6, 7a, 7b, 7c, and eh8 This is because it is necessary to widen the flow passage hole 322 when the concentration of raw water is high, and it is possible to make the flow passage hole relatively narrow in the case of ice making water. The assembly tube 32 can be assembled and coupled to the spiral portion 304 of the tubular portion 302 by threaded engagement with the spiral portion 323 so that the assembly tube body 32 having various diameters (a, b, c) (32).

FIG. 9A is an operational cross-sectional view of the present invention powder ice ice maker in a flow path interruption state, and FIG. 9B is an operational cross section of the present invention powder ice ice maker in a flow path open state.

9A and 9B, the engagement portion 314 of the control rod 31 is moved from the first placement portion 306 to the second placement portion 307 (see FIG. 9A) The lower end valve 313 of the valve stem 312 of the control rod 31 cuts off the flow passage hole 322 and blocks the discharge of the raw water in the raw water tank 301 as shown in FIG. 9A . 9B, when the holding portion 315 of the control rod 31 is held and rotated and is placed on the first placement portion 306, the control rod 31 and the valve stem 312 as a whole are moved upwards at a predetermined interval (a), and the flow passage hole 322 is opened. In this opening operation, the raw water flows through the first flow path 303, the second flow path 305, the flow passage hole 322, and is discharged to the downwardly extending ice-making water tank 2.

In this embodiment, the ice-making drum 1 is rotated at the moment when the powder ice container (cup) is dropped, and at the same time, after the rotation of the ice-making drum 1 is started, The outer peripheral surface of the drum is frozen due to the refrigerant applied inside the ice-making drum 1 at the same time as the ice-making drum 1 is rotated in the ice-making water tank 2 during the time of the ice- ), A certain amount of snow falls is dropped into the container. After the process of storing the powdered ice in the container is completed, the control rod 31 is rotated by rotating the grip 315 of the control rod 31 so that the icing water supply of the ice-making water tank 2 is stopped.

As described above, since the present invention is a small type ice maker that provides powder ice without a turntable for storing powdered ice and a pumping means for automatically feeding raw water, complicated pumping means according to the supply of raw water is removed, The supply cost of the raw water tank is reduced, and the driving of the cooling cycle unit A and the ice-making drum after the discharge of the raw water tank is stopped to reduce the consumption of electric power, (Unnecessary operation of the ice-making drum, that is, when the ice-making is not required, the operation is stopped to reduce the operation of the unnecessary cooling cycle of the ice-making drum, thereby consuming less power).

That is, the present invention improves the expansion of the space due to the component cost, assembly and layout design of the pump which is caused by pumping raw water of the raw water tank in the existing powder ice ice maker, thereby improving the problem of the size of the whole powder ice ice maker Thereby providing a compact powder ice ice maker having a greatly reduced size.

In addition, since the water supply of the raw material water tank is supplied or cut off due to the difference in the water level of the raw water tank, there is no generation of residual water after the temporary stop of the ice making operation. Thus, the clean environment is maintained and the sanitary property is emphasized. It is possible to provide an ice maker structure that is simple to remove.

In addition, the present invention provides a size that does not include a turntable for accommodating evenly powdered ice, which is contained in a container for storing powdered ice, when manufacturing a conventional external casing, It is possible to provide a water supply system with improved installation space and a problem of assembling property, thereby providing a compact ice maker which is suitable for repeatedly accommodating a small capacity ice maker in a container of a predetermined capacity.
