Description

Ice-maker {ICE MAKER}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ice maker for making ice, and more particularly to an ice maker in which an ice tray for containing water is moved up and down so that an immersion member for generating ice is locked.

An ice maker is an ice maker.

Such an ice-maker includes an ice-making tray containing water and an immersion member immersed in water contained in the ice-making tray, and an immersion ice-maker for cooling the immersion member by cooling unit to generate ice in the immersion member.

Further, there is a jet type ice maker for spraying water to the ice-making tray cooled by the cooling unit to generate ice in the ice-making tray.

There is also a water-based ice maker that causes water to flow through the ice-making tray cooled by the cooling unit to generate ice in the ice-making tray.

Meanwhile, in the conventional submerged ice maker, the ice-making tray includes a first tray rotatably provided and a second tray connected to the first tray at an angle.

With this configuration, after the first tray is rotated and the water is supplied to the first tray so that the immersion member can hold water to be immersed, the immersion member is cooled by the cooling unit so that ice is generated in the immersion member. Further, after ice is generated in the immersion member, the first tray is rotated to move the water remaining in the first tray to the second tray. Then, after the ice produced in the immersion member was separated from the immersion member, the separated ice was dropped on a grill inclined to the second tray and moved to the ice reservoir.

Thereafter, the first tray is rotated to move the water contained in the second tray to the first tray so that the immersion member is immersed in the water contained in the first tray. Then, after insufficient amount of water was supplied to the first tray, the immersion member was cooled by the cooling unit so that ice was generated again in the immersion member.

In the case of the submerged ice-making machine having such a constitution, low-temperature water close to the freezing point used for generating ice can be reused for generation of ice, thereby reducing ice generation time.

However, since a space for rotating the second tray together with the first tray is required, the size of the ice maker must be relatively large, and it has been difficult to accurately control the rotational position of the first tray. Further, in order to move the ice to the ice reservoir, noise was generated when the ice dropped from the immersion member into the grill of the second tray.

In the conventional submerged ice-making machine of other construction, the ice-making tray includes a single tray rotatably provided. However, in this configuration, the low-temperature water near the freezing point used for generating ice can not be reused for generating ice , The ice generation time was increased.

Also, in this configuration, since the ice-making tray rotates, a space for rotating the ice-making tray is required, so that the size of the ice-maker must be relatively large, and it is difficult to control the rotation position of the ice-making tray accurately.

In addition, a conveyance guide member is provided to move the ice dropped from the immersion member to the ice reservoir, but noise is generated when the ice drops on the conveyance guide member.

1, the ice maker 100 according to the present invention may include an ice-maker main body 200, a cooling unit 300, an ice-making tray 400, and a tray driving unit 500.

1 and 2, a space in which the cooling unit 300, the ice-making tray 400, and the tray driving unit 500 described above may be provided may be formed in the ice- . Also, the ice-maker main body 200 may be provided with a partition 210 as shown in FIG.

A moving space 211 in which a tray member 410 to be described later in which a space inside the ice-maker main body 200 is included in the ice-making tray 400 is moved up and down by the partition 210, And may be separated into a storage 212.

The ice reservoir 212 of the ice-maker main body 200 may be rotatably provided with a transfer screw (not shown) for discharging the stored ice I to the ice discharge port OI. The ice reservoir 212 of the icemaker main body 200 may also be provided with a screw driving motor (not shown) connected to the conveying screw to rotate the conveying screw.

As shown in FIGS. 1 and 2, a jaw 220 may be formed on the ice-maker main body 200. When the ice-making tray 400 is moved to a position as shown in FIGS. 8 and 9, the ice-making tray 400 is rotated to guide the turning guide 440, which will be described later, The swing member 440 can be rotated at a predetermined angle by contacting the jaw portion 220 of the icemaker main body 200. [

8 and 9, the ice (I) separated from the immersion member 210 and separated from the immersion member 210 (not shown) Can be moved to the ice reservoir (212) of the ice-maker main body (200) by the member (440).

The ice maker main body 200 may include a first magnetic force generating unit 230 for generating a magnetic force as shown in FIGS. In order to generate magnetic force, the first magnetic force generating unit 230 may include an electromagnet. However, the present invention is not limited to the electromagnet, and any magnetic force generating unit can be included in the first magnetic force generating unit 230.

A second magnetic force generating unit 442 to generate a magnetic force may be provided at a position of the swing member 440 corresponding to the first magnetic force generating unit 230 of the icemaker main body 200. [ For generating the magnetic force, the second magnetic force generating section 442 may include a permanent magnet. However, the present invention is not limited to the permanent magnet, and any element that generates magnetic force can be included in the second magnetic force generating portion 442.

The magnetic forces generated in the first magnetic force generating portion 230 of the ice-maker main body 200 and the second magnetic force generating portions 442 of the swing member 440 can interact with each other. Thereby, attraction force or repulsive force may be generated between the first magnetic force generating portion 230 and the second magnetic force generating portion 442. Further, if the attraction force and the repulsive force are generated alternately, the turning member 442 can be reciprocated as shown in Fig.

For example, when the first magnetic force generating portion 230 including the electromagnet is controlled to generate the attraction force and the repulsive force alternately between the first magnetic force generating portion 230 and the second magnetic force generating portion 442, The pivot member 440 can be reciprocated as shown.

Accordingly, waves generated in the water contained in the tray member 410 can be discharged, and the bubbles contained in the water can be discharged to the outside. Transparent ice (I) may be generated in the immersion member (310) contained in the cooling unit (300) to be described later and immersed in the water contained in the tray member (410).

1 and 2, the evaporator 320 and the defrosting heater 330 included in the cooling unit 300 to be described later are fixed to the ice-maker main body 200, respectively, The first bracket BR1 and the second bracket BR2 may be provided.

The cooling unit 300 may include an immersion member 310 as shown in FIGS. The cooling unit 300 may further include an evaporator 320 to which the immersion member 310 is connected and the refrigerant flows.

The evaporator 320, together with a compressor (not shown), a condenser (not shown), and an expansion valve or capillary (not shown), forms a refrigeration cycle in which the refrigerant flows while undergoing temperature, pressure and phase changes. The cooler or the hot coolant may flow to the evaporator 320.

When the cold refrigerant flows into the evaporator 320, the above-described immersion member 310 connected to the evaporator 320 can be cooled by heat transfer. Accordingly, the water containing the immersion member 310 is also cooled by heat transfer, and ice (I) can be generated in the immersion member 310 as shown in FIGS.

In addition, when the hot refrigerant flows into the evaporator 320, the immersion member 310 can be heated by heat transfer. For example, the refrigerant having a high temperature and high pressure passes through the compressor to the evaporator 320, thereby allowing hot refrigerant to flow to the evaporator 320, whereby the immersion member 310 can be heated.

The portion of the ice (I) generated in the immersion member 310 that is in contact with the immersion member 310 is melted so that the ice I can be separated from the immersion member 310.

The immersion member 310 may be connected to the evaporator 320 so that the refrigerant may also flow into the immersion member 310. The flow path of the immersion member 310 is connected to the flow path through which the refrigerant formed in the evaporator 320 flows and the flow path of the refrigerant flowing in the immersion member 310 The refrigerant can flow.

However, the immersion member 310 may be connected to the evaporator 320 so that the refrigerant does not flow into the immersion member 310.

As shown in FIGS. 1 and 3, the evaporator 320 may be equipped with a heater 330 for deaeration.

If the defrosting heater 330 is provided in the evaporator 320, even if the hot refrigerant does not flow to the evaporator 320 as described above, the evaporator 320 and the immersion member (I) generated in the immersion member 310 can be separated from the immersion member 310 by heating the immersion member 310.

The deasphalting heater 330 may be configured to generate heat when power is applied, for example. However, the structure of the deaeration heater 330 is not particularly limited, and any known structure may be used as long as it is provided in the evaporator 320 and can heat the immersion member 310 together with the evaporator 320.

Meanwhile, the cooling unit 300 may include a thermoelectric module (not shown) in addition to the evaporator 320 described above. The above-described immersion member 310 may be connected to the thermoelectric module. For example, the immersion member 310 may be connected to the thermoelectric module by a connecting member (not shown) on one side to contact the thermoelectric module and the other side to which the immersion member 310 is connected.

However, the structure in which the immersion member 310 is connected to the thermoelectric module is not particularly limited, and any well-known structure is possible as long as the immersion member 310 is connected.

The thermoelectric module may have heat transfer from one side to the other side when power is applied. Accordingly, when power is applied to the thermoelectric module to allow the immersion member 310 to cool, ice (I) may be generated in the immersion member 310. In addition, when a power source in the opposite direction is applied to the thermoelectric module, the immersion member 310 is heated so that the ice (I) generated in the immersion member 310 can be separated from the immersion member 310.

A heat transfer member (not shown) having a cooling fan (not shown) may be connected to the thermoelectric module on the opposite side to which the immersion member 310 is connected. Accordingly, the opposite side of the thermoelectric module heated by the heat transfer by application of the power supply can be cooled by the cooling fan and the heat transfer member. Therefore, the cooling by the thermoelectric module can be continued and the cooling efficiency may not be lowered.

4 and 5, the ice-making tray 400 may contain water so that the immersion member 310 is immersed therein. To this end, the ice-making tray 400 is positioned below the immersion member 310 and water can be supplied from a water supply source (not shown). For example, a water supply pipe (not shown) connected to a water supply source is located at a predetermined distance from the top of the ice-making tray 400, and water of the water supply source can be supplied to the ice-making tray 400 through a water supply pipe.

4 to 9, the ice-making tray 400 can be moved up and down by a tray driving unit 500 to be described later. In this way, since the ice-making tray 400 is moved up and down without being rotated as in the conventional ice-maker, a space for rotating the ice-making tray 400 is not required in the ice- Accordingly, the size of the ice maker 100 can be reduced. Further, since the ice-making tray 400 moves only vertically, its position can be easily controlled.

The ice-making tray 400 is movable between an ice-making position as shown in Figs. 4 and 5, a de-icing position as shown in Figs. 6 and 7, and a storage position as shown in Figs. have. Further, the defrosting position may be located below the defrosting position, and the storage position may be located below the defrosting position. However, the moving position of the ice-making tray 400 is not particularly limited, and any position is possible.

As shown in FIGS. 4 and 5, when the ice-making tray 400 is moved to the ice-making position, ice (I) may be generated in the immersion member 310. For example, at the ice making position, water is supplied to the ice-making tray 400 from the water supply source as described above, so that the immersion member 310 can be immersed in the water contained in the ice-making tray 400. Then, the cold refrigerant flows to the evaporator 320 so that ice (I) can be generated in the immersion member 310.

6 and 7, the ice (I) separated from the immersion member 310 can be moved to the ice-making tray 400. As shown in FIG. For example, the deicing heater 330 is operated so that the ice (I) generated in the immersion member 310 can be separated from the immersion member 310 and moved to the ice-making tray 400. That is, the ice (I) can be separated from the immersion member (310) and fall into the water contained in the ice-making tray (400).

8 and 9, when the ice-making tray 400 is moved to the storage position, the swivel guide portion 441 of the swivel member 440, as described above and described later, The ice I in the ice-making tray 400 can be moved to the ice reservoir 212 of the ice-maker main body 200 by the swivel member 440 by being rotated at a predetermined angle.

After the ice I separated from the immersion member 310 drops into the water contained in the ice-making tray 400 and is then moved to the ice-storing chamber 212 of the ice-maker main body 200 by the swiveling member 440 Therefore, noise may not be generated when the ice (I) is moved to the ice reservoir (212). Therefore, the noise of the ice maker 100 can be reduced.

On the other hand, although not shown, the ice-making tray 400 can move only between the ice-making position and the ice-making position. In this case, the defrosting position is the same as the position shown in Figs. 4 and 5, but the defrosting position is the position shown in Figs. 8 and 9, not the positions shown in Figs. Further, the deicing position may be located below the deicing position. However, the moving position of the ice-making tray 400 is not particularly limited, and any position is possible.

Even in this case, when the ice-making tray 400 is moved to the ice-making position, ice (I) may be generated in the immersion member 310. For example, water is supplied from the water supply source to the ice-making tray 400 so that the immersion member 310 can be immersed in the water contained in the ice-making tray 400. When cold refrigerant flows into the evaporator 320, ice (I) may be generated in the immersion member 310.

In this case, when the ice-making tray 400 is moved to the de-icing position, that is, the position shown in Figs. 8 and 9, the ice I is separated from the immersion member 310 and moved to the ice bin 212 . The swivel guide portion 441 of the swivel member 440 may contact the jaw portion 220 of the ice maker main body 200 and be turned at a predetermined angle. In this state, the heater 330 for deaerating is operated so that the ice (I) generated in the immersion member 310 can be separated from the immersion member 310. The ice (I) separated from the immersion member (310) can fall into the swirling member (440) which is pivoted at a predetermined angle. The ice (I) can be moved to the ice reservoir (212) of the ice maker main body (200) by the revolving member (440).

On the other hand, the ice tray 400 can be easily moved back to the ice making position by the tray driving unit 500, which will be described later. In addition, since the ice-producing water can be moved while being placed in the ice-making tray 400 at the time of moving the ice-making tray 400, the water at a low temperature close to the freezing point used for the generation of ice (I) Can be reused for the production of ice (I). Thus, the ice generation time can be reduced.

The ice-making tray 400 may include a tray member 410 as shown in FIGS. The tray member 410 may be filled with water as shown in FIGS. To this end, the tray member 410 may be provided with a space for storing water.

As shown in FIGS. 1 and 3, the ice-making tray 400 may further include a guide member 420 and a connecting rod 430. The guide member 420 may be movably provided in the tray driving unit 500 to be described later. For example, the guide member 420 may be movably installed in the driving unit main body 510 included in the tray driving unit 500, as described later. The connecting rod 430 may connect the tray member 410 and the guide member 420. For this purpose, the tray member 410 and the guide member 420 may have a fitting hole 422 through which one end and the other end of the connecting rod 430 are respectively fitted.

Accordingly, when the guide member 420 is moved up and down by the tray driving unit 500 to be described later, the tray member 410 can be moved up and down together with the guide member 420.

The ice-making tray 400 may further include a pivot member 440 as shown in FIGS.

The pivot member 440 may be pivotally mounted on the tray member 410. As shown in FIGS. 1 and 3, the revolving member 440 may be plate-shaped. Also, as shown in the figure, the swivel joints 411 and 411 'having a ring-like shape may be formed on one side and the other side of the tray member 410, respectively. The pivot shafts 443 and 443 formed on the pivot member 440 are fitted to the pivot connection portions 411 and 411 'of the tray member 410 so that the pivot member 440 can be pivotally mounted on the tray member 410 .

However, the configuration of the pivoting member 440 and the configuration in which the pivoting member 440 is pivotally mounted on the tray member 410 is not particularly limited, and any shape or configuration can be used.

The turning member 440 may be provided with a turning guide unit 441 as shown in FIGS. The turning guide portion 441 may be provided at the left end of the turning member 440 as seen in the drawing. However, the position of the swivel guide portion 441 in the swivel member 440 is not particularly limited, and any position is possible.

The swivel guide portion 441 contacts the chin portion 220 of the ice maker main body 200 by the movement of the ice tray 400 and the swivel member 440 can be pivoted by a predetermined angle. Then, the ice (I) can be moved to the ice reservoir 212 of the icemaker main body 200.

8 and 9, the swivel guide portion 441 of the swivel member 440 is moved by the movement of the ice-making tray 400 to the ice-maker main body 200 The swing member 440 can be rotated at a predetermined angle. Thereby, the ice (I) dropped in the water contained in the tray member 410 separated from the immersion member 310 of the cooling unit 300 at the ice-making position is lifted by the swing member 440, To the ice reservoir 212 of the ice maker 200.

When the ice-making tray 400 is moved up and down only between the positions shown in Figs. 4 and 5 and the positions shown in Figs. 8 and 9 as described above, 8 and 9, the swivel member 440 may first be pivoted by the jaw 220 of the ice maker main body 200 at a predetermined angle.

Thereafter, the ice (I) may be separated from the immersion member 310 of the cooling unit 300 and dropped onto the swivel member 440. The ice I dropped on the revolving member 440 can be moved to the ice reservoir 212 of the ice maker main body 220 by the revolving member 440.

As shown in FIG. 3, the revolving member 440 may include a second magnetic force generating unit 442. The second magnetic force generating unit 442 may be provided at the right end of the pivot member 440 as shown in the drawing. However, the position of the second magnetic force generating portion 442 in the revolving member 440 is not particularly limited and may be any position.

The second magnetic force generating section 442 can generate a magnetic force. For this purpose, the second magnetic force generating section 442 may include a permanent magnet. However, the configuration for generating the magnetic force in the second magnetic force generating section 442 is not particularly limited, and any well-known configuration can be used as long as it can generate magnetic force.

The first magnetic force generating unit 230 may be provided at a position of the ice maker main body 200 corresponding to the position of the second magnetic force generating unit 442. The first magnetic force generating unit 230 may generate a magnetic force. For this purpose, the first magnetic force generating unit 230 may include an electromagnet. However, the configuration for generating the magnetic force in the first magnetic force generating section 230 is not particularly limited, and any configuration can be used as long as it generates a magnetic force.

The magnetic force generated by the first magnetic force generating unit 230 and the magnetic force generated by the second magnetic force generating unit 442 can interact with each other. Accordingly, attraction and repulsive force due to the magnetic force may occur between the first magnetic force generating portion 230 and the second magnetic force generating portion 442.

If the attraction force and the repulsive force are generated alternately, the turning member 440 can be reciprocated as shown in FIG. By controlling the first magnetic force generating section 230 including the electromagnet to generate the attraction force and the repulsive force alternately between the first magnetic force generating section 230 and the second magnetic force generating section 442, Can be reciprocated.

As a result, the water contained in the tray member 410 generates waves, and the bubbles contained in the water can be discharged to the outside. Transparent ice (I) may be generated in the immersion member (310) of the cooling unit (300) immersed in the water contained in the tray member (410).

As shown in FIG. 3, a through hole 444 may be formed in the swivel member 440. The water contained in the tray member 410 can pass through the through hole 444 of the swing member 440 when the swing member 440 reciprocates as described above. Thus, the swirling of the swing member 440 can be easily performed.

The tray driving unit 500 may move the ice-making tray 400 up and down as shown in FIGS. 1 and 3, the tray driving unit 500 may include a driving unit body 510, a driving motor 520, and a gear 530.

The guide member 420 of the ice-making tray 400 may be movably provided in the drive unit main body 510. [ As shown in FIG. 3, the driving unit main body 510 may include a guide rod 511. The guide member 420 may be formed with a guide hole 421 through which the guide rod 511 passes. Accordingly, the guide member 420 can be movably provided in the driving unit main body 510. [

However, the structure in which the guide member 420 is movably provided in the drive unit main body 510 is not particularly limited, and any known structure may be used as long as the guide member 420 is movable.

The driving motor 520 may be provided in the driving unit main body 510. Then, the gear 530 may be connected to the drive motor 520. Further, the gear 530 can be engaged with the gear portion 423 formed on the guide member 420 as shown in Figs. 5, 7, and 9. For example, the gear portion 423 of the guide member 420 may be formed at a position corresponding to the gear 530, that is, on the right rear surface of the front portion of the guide member 420 as viewed in FIG.
