Description

SNOW ICE MAKER}

The present invention relates to an ice-making machine for ice-making (ice-making) water for ice-making and ice-making water for ice-making (ice-making water) (Hereinafter referred to as " water ") is supplied by a non-powered method without pumping drive.

Generally, in the powder ice machine, a cylindrical ice making drum is rotatably installed inside a raw water bath, a part of the ice making drum is immersed in the raw water bath, and a freezing cycle A refrigerant circulation system in which a compressor, a condenser, and an expansion valve are connected to each other by a refrigerant pipe, hereinafter referred to as a cooling cycle unit), and at the same time as the cooling drum rotates, ice is grown on the surface of the ice- There is known a drum-type powder ice ice maker in which a horizontal blade which is in contact with a frozen ice layer with a fine gap is fixed, so that the ice on the surface of a rotating ice-making drum is scraped off by a blade or a container.

Such a drum-type powder ice ice maker is disclosed in, for example, JP-A-1993-0000306 and JP-A-2006-0059632. However, the former has a problem of heat transfer efficiency and the latter has a problem that a uniform ice- No. 0821558, No. 0888528, No. 0889528, No. 0825980, which is an improvement of the drum structure to improve the ice-making efficiency of the drum type ice maker, 1999-0022144 and the like.

On the other hand, devices such as a water purifier, a bidet, a humidifying device, and an ice-making device are provided with a fluid tank (also called a raw water tank including a liquid such as juice) A water level sensing device is installed in order to keep the level of liquid such as water constant. The level sensing device may be of a mechanical type or an electronic type.

The mechanical type of the level detecting apparatus senses the level of the liquid by sensing a change in the magnetic force as the float moves up and down due to buoyancy of the liquid.

The electronic type of water level sensing apparatus includes a capacitive sensor for sensing the level of the liquid by detecting a change in the electrostatic capacity.

However, such conventional level sensing devices require a mechanical operation of the float, so that the operation may be poor due to the mechanical structure of the float. Further, since the operation of the float becomes poor, the detection of the magnet becomes poor, so that the level of the liquid contained in the fluid tank may not be accurately measured. In addition, due to the mechanical structure of the water level sensing device, a float or float supporting structure may be contaminated with foreign matter such as water, and the magnetic force may not be normally detected. Particularly, when the water level is removed after separating the mechanical type water level sensing device, the mechanical complexity of the water level sensing device makes it difficult to remove foreign matter or increase the cleaning time.

A common problem with the conventional drum type ice-making ice ice-makers is that although an ice maker for obtaining powder ice needs to be downsized in accordance with the intended use, There is a problem in that the structure is complicated and the manufacturing cost is also increased due to the inconvenience of cleaning the assembly and the water tank.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Generally, the ice maker sequentially circulates the refrigerant while the compressor (A1), the condenser (A2), the expansion valve (A3) and the evaporator (A4) form one cooling cycle, and the external heat is circulated through the evaporator A4 is a drum type ice maker based on a cooling cycle unit A for taking heat around and cooling it and for taking out heat from outside in the ice making drum 1 in contact with water to form ice. As shown in FIGS. 1A and 1B, the ice making machine of the present invention 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.

According to the above-mentioned drawings, the powder ice ice maker of the present invention is characterized in that the ice-making drum 1 in which the evaporation refrigerant of the cooling cycle unit A is freezing the drum outer circumferential surface from the inside of the cylindrical drum, A raw water supply portion 3 for supplying raw water to the raw water tank; a blade portion 4 provided on the outer circumferential surface of the front surface of the ice-making drum for scraping freezing ice on the outer circumferential surface thereof; And a bottom surface of the ice making compartment is formed of a casing having a predetermined shape for covering the interior of the ice making compartment, A housing 5, a driving unit 6, and a power supply unit (not shown).

The cooling of the ice-making drum 1 is carried out in such a manner that the evaporator A4 to which the refrigerant expanded by the expansion part A3 of the cooling cycle part A is supplied is injected from the nozzle or the like at the inner center of the ice- So that the raw water is frozen on the outer peripheral surface of the ice-making drum 1.

The ice-making water tank (2) allows the raw water to be contained in the ice-making water tank (2) in the raw water tank (30) of the raw water supply part (3). The raw water of the ice-making bath 2 is maintained in an immersed state so that the outer peripheral surface of the ice-making drum 1 is contacted with a predetermined depth. The ice-making water tank 2 is positioned directly below the ice-making drum 1 so that the outer peripheral surface of the ice-making drum 1 is in contact with the rotation.

As shown in FIGS. 3 to 5, the raw water supply part 3 is structured such that it can be easily separated and assembled by a user, unlike a generally known raw material supply water tank. The separation of the raw water supply part 3 is a structure in which the raw water tank 30, from which the raw water is completely discharged from above the external enclosure 5, is simply separated when the user moves upward. The raw water supply part 3 can be applied with the upper grip part 315 of the control rod 31 exposed to the lid 308 side (a detailed description will be given later).

The blade portion 4 is provided so as to be in contact with the outer peripheral surface of the ice-making drum 1 immediately below the front outlet portion of the powder ice ice-maker of the present invention. As the ice-making drum 1 is rotated, the blade 4, which is in contact with the outer circumferential surface of the ice-making drum 1, can scrape ice I which is freezing on the outer peripheral surface of the ice-making drum 1. The rotation of the ice-making drum 1 can be transmitted through a driving motor, a speed reducer, or pulleys or chains fixed on one side.

A direct-view air space in which the snowboard falls is formed as an opening, a container (cup) for housing the snowboard is positioned on the floor, and a floor (not shown) on which a known turntable is driven It will be possible to install the structure separately. The present invention implements a compact powder ice ice maker without such a turntable.

A direct-view air space in which the snowboard falls is formed as an opening, a container (cup) for housing the snowboard is positioned on the floor, and a floor (not shown) on which a known turntable is driven It will be possible to install the structure separately. The present invention implements a compact powder ice ice maker without such a turntable. Similar to the shape of a known small water purifier or domestic water purifier, the remainder excluding the front surface is a casing of a cube (to be described later).

The drive unit 6 may be constructed such that a driven pulley is installed on one side of the ice-making drum 1, and a rotational force through the drive motor and the speed reducer is connected to the driven pulley via a main pulley. The structure for rotating the ice-making drum 1 may be the same as that of the conventional drum ice-maker (Utility Model Application No. 20-02015-0002301) or may be directly connected to the drive motor. A detailed description thereof will be omitted.

The power supply unit supplies power to the cooling cycle unit A and the driving unit 6, and its installation structure is well-known, and a detailed description thereof will be omitted.

As shown in Fig. 4A, the raw water supply portion 3 is divided into a raw water tank 30, a control rod 31, and a tube assembly 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 the center of the first and second placement units 306 and 307. [

5, the internal flow path of the tubular portion 302 is formed to have a height along the inner peripheral surface of the bottom-side first flow path 303 of the raw material water tank 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 the drawing, the tubular portion 302 is preferably of the assembled type in which the valve seat 321 is screwed into 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. 6A, 6B and 6C, the assembly tube body 32 can be realized with the assembly tube body 32 having diameters (a, b, c) of various diameters 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 .

7, the control rod 31 of the present invention will be described. The control rod 31 forms a relatively narrow second spacing portion 317 in a predetermined longitudinal section of the lower longitudinal direction of the central valve stem 312 and a relatively wide second spacing portion 317 is formed in a predetermined section of the longitudinal middle portion of the valve stem 312. A first gap holding portion 316 is formed and a latching portion 314 extending in the transverse direction is formed at a predetermined position of the second gap holding portion 316. [ 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 grasping portion 315 formed at the upper end is rotated in the perpendicular direction in the horizontal state, the control rod 31 is placed on the first placement portion 306 or on the second placement portion 307, , The center of the control rod 31 does not flow and can move upward and downward, so that the flow passage hole 322 can be opened and closed.

4B and 4C, the latching portion 314 is caught and placed in the first placement portion 306 of the tubular body portion 302, but may be rotated at the right angle to be located in the second placement portion 307. [ 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 the diameter of the flow passage hole 322 of the assembly tube 32 can be varied as shown in FIG.
The reason for this is that when the concentration of raw water is high, the flow passage hole 322 needs to be widened, and in the case of pure water (ice making water) having no concentration, the flow passage hole can be made relatively narrow. 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).

8A is a functional sectional view of the powder ice ice maker according to the present invention in a flow passage cut-off state, and FIG. 8B is a functional cross-sectional view of the powder ice ice maker according to the present invention.

8A and 8B, 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. 8A) 8A, the lower end valve 313 of the valve stem 312 of the control rod 31 cuts off the flow passage hole 322 to cut off the discharge of the raw water in the raw water tank 301 . 8B, when the grip 315 of the control rod 31 is held and rotated and is placed on the first placement portion 306, the entire control rod 31 and the valve stem 312 are moved upwards at predetermined intervals (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.

9 is a view of another embodiment showing that the grasping portion of the control rod of the powder ice ice maker of the present invention is exposed to the outside of the lid and rotates and closes the control rod in the lid.

That is, the powder ice ice maker according to the present invention can be applied to the lid 308 side as well as the bottom of the raw material water tank 30 as shown in Fig. The cover 308 may be implemented as a floor as shown in FIG. That is, the upper surface (control rod exposure position) of the lid 308 constitutes the first placement unit 306, and the first placement unit 307 is implemented in a groove shape at a lower position, So that the latching portion 314 formed on the latching portion 314 can be raised or lowered.

10 is an exemplary view showing still another embodiment of the rotation opening / closing structure of the control rod of the powder ice ice maker of the present invention.

10, the control rod 31 applied to the inventive powder ice ice maker is provided with a placement table 309 in parallel with the inlet of the first flow path 303 inside the raw water tank 30, The passage hole 322 can be opened or closed as the latching portion 314 of the first passage 31 is raised on the mounting table 309 or falls on the first passage 303 side.

Therefore, when the stopper 314 is placed on the mounting table 309, the control rod 31 is lifted by the distance a. When the stopper 314 is rotated at right angles and placed between the mounting tables 309, the entire control rod 31 is lowered, Thereby blocking the through hole 322.

When the engaging portion 314 formed on both sides of the intermediate portion of the valve stem 312 is placed on the first placement portion 306, the control rod 31 is positioned at the raised position, The flow passage hole 322 of the sheet 321 is opened to supply the raw water in the raw water tank 30.

When the discharge of the powdered ice is finished once, the valve stem 312 of the gripping part 315 is rotated at right angles to rotate the engaging part 314 in a direction perpendicular to the second mounting part 307 Closing valve 311 formed integrally with the valve stem 312 is lowered to the flow passage hole 322 of the valve seat 321 to block the supply of the running water.

Although the present invention is not shown, a male screw is formed on any one of the first and second gap holding portions 316 and 317 of the control rod 31 and the first and second A female screw threadably engaged with the two flow paths 303 and 305 is formed so that the lifting height can be adjusted by screwing the control rod 31 and the flow passage hole 322 can be opened and closed.

11A and 11B are perspective views showing an outer shape of the powder ice ice maker of the present invention.

As shown in the drawing, the powder ice ice maker of the present invention can be implemented by the type shown in FIG. 10A which protects the inside as an external housing 5, and the type shown in FIG. 10B which protects a portion where powder ice is discharged have. That is, the outer housing 5 can prevent the side cover 52 from coming into contact with the wind blowing from the outside in the front-side viewing direction.

In the ice-making machine according to the present invention, the ice-making drum 1 is rotated at the moment when the powder ice container (cup) is dropped, and at the same time 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, the present invention is a simple type small ice-maker that provides powder ice without a turntable for storing powdered ice and a pumping means for automatically supplying raw water. Therefore, 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 expansion of the space due to designing of the parts cost, assembly and layout of the pump, which is caused by pumping raw water of the raw water tank in the conventional powder ice ice maker, thereby improving 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 feed water in 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 so that the cleaned state is maintained and the sanitary property is emphasized. The flow passage 322 is blocked by the raw water or the juice such as juice or the like and is easily separated and cleaned for cleaning and the whole of the raw water tank 30 and the tubular part 302 is stripped It is possible to provide an ice maker structure in which internal cleaning and the like are simplified.

In addition, the present invention provides a size that does not include a turntable for accommodating evenly-crushed 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.
