In the descriptions relating to the above, the direction is set according to this standard.

In addition, in the following description of the ice making apparatus according to the present invention has been described on behalf of the ice making mechanism that can be applied to conventional drinking water supply apparatus, such as an ice water purifier, this is for convenience of description, in addition to the drinking water supply device, refrigerator, ice generation Naturally, it can be applied to all kinds of apparatuses for providing various kinds of ice, such as apparatuses, which can be modified, substituted, and modified by those skilled in the art with sufficient prediction.

Hereinafter, the ice making apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

First, the ice making and ice water combining ice making mechanism according to the present invention includes an ice making container 10 filled with ice making water, as shown in FIGS. 1 to 3; A cold water container 20 positioned below the ice container 10 for supplying cold water; And an ice making body 110 including an evaporating tube 111 through which a refrigerant flows, and a plurality of ice making nozzles 113 protruding from the evaporating tube 111 and immersed in the ice making water to perform de-icing and de-icing. It comprises a; ice making means (100).

The ice making water may be made of a bottle of water, such as a water supply unit (W) provided on one side of the ice making apparatus of the present invention, and may be subjected to purified water through a filter assembly as necessary (when ground water is contained in the bottle of water).

As the water supply unit (W) can be configured in the form using both tap water and bottled water.

In addition, the ice making water includes all the water used for ice making described later, and should not be construed as being limited to water for ice making only.

The ice making container 10 is almost the same as known technologies, and may include a supply unit for supplying ice making water, a discharge unit for discharging water, and a conveying means for transferring the finished ice to a separate ice storage container. For convenience of description, detailed configurations and connection relationships will be omitted.

Since the compressor 120, the condenser 130, and the converter 140 described above are those that are used in a conventional ice making mechanism, they are sufficiently predictable by those skilled in the art, and thus, the operating principle and detailed structure of the present specification are provided for convenience of description. Omit for this reason.

The ice making apparatus according to the present invention freezes ice making water in contact with the ice making nozzle 113 provided in the ice making body 110 by flowing a refrigerant for making ice through the ice making means 100.

To this end, the ice making nozzle 113 of the ice making body 110 is partly immersed in the ice making water of the ice making container 10 and the refrigerant flows from the ice making means 100 to perform ice making by using the cool heat of the refrigerant. can do.

The ice making body 110 includes an evaporation tube 111 and an ice making nozzle 113, and the ice making nozzle 113 is a protrusion that is similar to a nipple of a cow as a protruding protrusion and a refrigerant circulates. A plurality of ice making nozzles 113 having passages may have a known shape.

Subsequently, in the present invention, a hot gas of high temperature and high pressure is supplied to the ice making body 110 by the opening of the valve after the ice making is completed to melt the contact surface of the ice formed in contact with the ice making nozzle 113 to remove the ice.

To this end, the ice making body 110 may be further provided with a deicing line for supplying hot gas for deicing the ice making nozzle 113.

That is, the ice making apparatus according to the present invention opens the solenoid valve of the ice-breaking line by flowing the high-temperature and high-pressure gas generated from the compressor 120 to the ice-making body 110 to defrost ice from the ice making apparatus after ice making. Defrosting is performed by melting the contact surface of the nozzle 113.

However, in an ice making mechanism in which ice making and de-ice are repeatedly performed, when the refrigerant flows for ice making operations, the second passage of the ice making body 110 and the external room temperature, which have risen in temperature due to the hot gas flowing for the previous ice making, Due to heat absorption in the refrigerant, the temperature of the refrigerant rises or the temperature of the ice making body 110 rises, so that the temperature cooling time due to the cooling of the refrigerant takes a long time and the efficiency of the ice making mechanism decreases, thus making the ice making time long.

Therefore, the present invention is as shown in Figure 1 and 2, the defrosting line 150 is arranged in the evaporator tube 111 is spaced apart from the refrigerant inlet portion of the first entry when hot gas is provided on the refrigerant inlet side during defrosting Not via one or more initial ice making nozzles,

One or a plurality of initial ice making nozzles provided on the refrigerant inlet side is configured as a nozzle for forming cold water of the cold water container.

By allowing the cold water dedicated nozzle 115 to be immersed in the cold water container 20, the cold heat for ice making may also be used to form cold water, thereby simultaneously forming cold water and ice making with one ice making means 100.

In addition, the present invention connects the deicing line 150 to which the hot gas flows so as not to communicate with the cold water nozzle 115 so that the ice making body 110 repeatedly performs de-icing and de-icing, thereby forming cold water at all times. Do.

That is, a predetermined number of ice making nozzles 113 adjacent to the refrigerant supply unit 111A of the ice making nozzles 113 of the ice making body 110 submerged in the ice making body are kept in iced state to constantly cool the ice making water. Cold water is formed, and the ice making nozzle 113 other than the cold water dedicated nozzle 115 may provide ice to the user by repeating ice making and de-ice, thereby forming a single ice making means 100 (cooling means for forming cold water). ), It is possible to generate ice and form cold water, which can reduce power consumption.

Subsequently, in a water purifier or the like which combines the function of providing conventional ice, the prior arts are not limited to providing a cold beverage or food to a user by simply providing ice,

Many technologies have been proposed to satisfy the user's aesthetic preference by providing transparent ice that does not contain air inside.

However, when only the lower part of the ice making nozzle is submerged in ice making water to produce ice or fills the ice bucket and is embedded in a conventional freezer to produce ice, water at 0 ° C has a lighter specific gravity than water at 4 ° C. Ice making is made from the upper part of the ice-making nozzle in which the ice-making nozzle is locked or the upper part of the ice container built in the freezer,

Since ice is generated from the upper side to the lower side, air contained in the lower ice-making water cannot be discharged, and thus opaque ice including bubbles is generated.

Conventional deicing techniques have suggested techniques for producing transparent ice through various methods. The complex structure or transparent ice is not produced smoothly, resulting in extremely low efficiency and an increase in manufacturing cost. It puts a lot of pressure on the user.

In order to solve the above problems, the ice making mechanism according to the present invention is characterized in that it is possible to generate transparent ice without air in the ice making nozzle 113 through a simple structure.

To this end, the present invention is further provided with a water level sensor consisting of a first sensor for detecting the full water level of the ice-making water and a second sensor for detecting the low water level in the ice tray,

The ice making water of the ice making container is continuously supplied to the ice making container until the water level detection sensor detects the full water level, and discharged to the outside of the ice making container until the low water level detection after the full water level detection.

Ice making is performed while the supply and discharge of the ice making water is repeated.

Therefore, the present invention is provided with a water level detection sensor (S) for detecting the water level of the ice-making water in the ice making container 10 to repeat the supply and discharge of the ice-making water according to the water level from time to time, the ice-making water to start ice-making to the outside As the air contained in the ice-making water is exposed and discharged, ice-making may be performed to produce transparent ice.

That is, by repeatedly supplying and discharging the ice-making water, only water contacting the outer circumferential surface of the ice-making nozzle 113 is instantly frozen, and then ice is sequentially generated from the surface of the ice-making ice to be opaque including bubbles such as air. It can prevent the formation of ice.

Furthermore, the present invention is characterized in that the ice-making water (ice-making residue) is transferred to the cold water by transferring the ice-making water discharged from the ice-making barrel to the cold water tank.

To this end, the present invention comprises a supply means consisting of a supply line including a water supply unit (W) and a first supply unit for supplying water to the ice tray (10) and the cold water tank (20),

The supply line includes a pump (P) having a solenoid valve for controlling water supply through opening and closing, and a second supply part and a third supply part for communicating the ice making container 10 and the cold water container 20 with each other. Can be done.

In more detail, the supply line may include a first supply part 31 for supplying water from the water supply part W to the ice making container 10 and the cold water container 20;

A second supply part 32 connected to the first supply part 31 to supply water to the cold water tank 20;

A third supply part 33 connected to the first supply part 31 to supply water to the ice making container 10,

A pump P having a solenoid valve is provided at a connection portion between the first supply part 31, the second supply part 32, and the third supply part 33 to provide the ice making container or the cold water container from the water supply part W. Or continue to provide water to all of them,

When the water level is detected, the ice making water of the ice making container may be discharged to the cold water container through the second supply part and the third supply part of the supply line.

Hereinafter, the generation of transparent ice and the formation of cold water through the second supply part, the third supply part, and the water level sensor S of the supply line will be described in detail with reference to FIGS. 1 to 3.

First, the ice making apparatus according to the present invention flows into an ice making body (110) consisting of an evaporating tube (111) and an ice making nozzle (113) protrudingly coupled from the evaporating tube (111). The ice making nozzle 113 submerged in the ice making water of the ice making container 10 performs ice making by using cold heat of a refrigerant.

In this case, as described above, in the present invention, the cold water forming nozzle 115 is exposed to a cold water container to form cold water at the same time as ice making.

And the ice-making water of the ice-making bin is repeatedly supplied and discharged to enable the production of transparent ice, and the ice-making water discharged from the ice-making bin is transferred to the cold water tank to be converted into cold water. In addition to making ice and cold water, it is possible to increase the efficiency of ice making and cold water formation.

The ice making mechanism according to the present invention for the repeated supply and discharge of the above-mentioned ice-making water further comprises a control unit (not shown) for controlling the solenoid valve provided in the pump (P),

The control unit closes the solenoid valve when the water level detection sensor S detects the full water level, so that the ice making water of the ice making container 10 passes through the second supply part 32 and the third supply part 33. ),

When the low water level is detected, the solenoid valve may be opened to supply ice making water from the water supply unit W to the ice making container 10.

Referring to Figure 3 described in more detail the supply and discharge of the ice-making water described above as follows.

First, a continuous water supply is made, and when the first sensor S1 detects the full water level of the ice making container 10, the controller closes the solenoid valve so that the first supply part 31 and the second supply part ( 32) and the connection of the third supply 33, the pump (P) is also stopped at this time water supply is stopped.

When the water supply is stopped, the second supply part 32 and the third supply part 33 remain filled with water, and the potential energy is increased due to the difference between the heights of the ice making container 10 and the cold water container 20. As a result, the ice making water of the ice making container 10 naturally falls into the cold water container 20 so that the ice making water is discharged automatically.

Subsequently, when the discharge of the ice making water progresses and the second sensor S2 of the ice making container 10 detects the low water level of the ice making water, the controller opens the solenoid valve to open the first supply part 31 and the second. The supply part 32 and the third supply part 33 communicate with each other, and the pump P operates to supply water again to supply the ice making water to the ice making container 10.

In this case, the shape of the second supply part 32 and the third supply part 33 and the connection relationship between the ice making container 10 or the cold water container 20 can be made in various ways, but the present invention provides more smooth discharge of ice making water. In order to make it possible and to take into account various internal structures such as a water purifier to which an ice making mechanism is applied, in order to prevent the problem that the ice-making water discharge structure cannot be achieved through potential energy due to the limitation of the structure,

The present invention adopts a design in which the second supply part 32 and the third supply part 33 form a siphon tube.

The shape of the siphon tube is that the liquid contained in two cylinders of different heights is connected to the pipe bent upward by the difference in atmospheric pressure, using the principle of the siphon that flows to a low place of high water, conventionally Flush toilets are a typical example.

Therefore, the present invention is designed to bend the second supply unit 32, such as a 'b' or '∩' type, and automatically stops the ice making container by using the principle of the siphon when the ice-making water supply of the control unit is stopped. By allowing the ice making water to discharge into the cold water container,

The ice-making water of the ice-making tank 10 can be discharged to the cold water tank 20 without being limited by structural limitations such as a water purifier in which an ice-making mechanism is incorporated, so that an operation or additional structure of a pump for discharging ice-making water is not introduced. Therefore, it is possible to simplify the structure, thereby lowering the manufacturing cost and increasing the convenience of manufacturing.

In FIG. 3, the siphon tube having the second supply part formed in a 'b' shape is illustrated, but this is for convenience of description, and the siphon tube may be modified in various forms using the above-described siphon principle.

In addition, in the present invention, if the water supply from the water supply unit (W) to the cold water tank 20 is continued, since the problem of overflowing the water exceeding the capacity of the cold water tank 20 may occur, the cold water tank 20 It is preferable to further adjust the water level of the cold water tank 20 by further comprising a detection sensor (not shown) for detecting the water level.

In order to control the water level of the cold water container 20, the solenoid valve has a multiple structure. When the valve is opened, only the first supply part 31 and the second supply part 32 communicate with each other, and the first supply part 31 It can be variously modified to block the third supply unit 33, or to communicate the first supply unit 31 and the second supply unit 32 and the third supply unit 33,

The multiple structure of the solenoid valve is a conventional technique used in the prior art (commonly known as 2WAY solenoid valve, 3WAY solenoid valve, etc.), and those skilled in the art can fully reproduce the prediction, the operation principle of the solenoid valve and the essential features of the present invention Since is less relevant, detailed description is omitted.

In addition, the ice making mechanism according to the present invention is impossible to discharge the above-mentioned ice-making water when the cold water tank 20 is full water level when the ice-making tank 10 is discharged, the discharge of the ice-making water is made of the water supply unit (W) Formed to

When supplying the ice-making water to the ice-making barrel can be formed to increase the ice making efficiency by supplying the cold water of the cold water tank dedicated to the ice-making water instead of the water supply,

In addition, it can be easily reproduced by those skilled in the art through the structure of the solenoid valve, and the communication relationship of the supply line or the flow of ice-making water (water) and the like are similar to those described above, and thus will be omitted for convenience of description.

In addition, the speed at which the ice-making water is supplied to and discharged from the ice making container 10 may be adjusted by selecting a unit supply or a unit discharge by varying the specifications of the supply lines 31, 32, 33.

Therefore, the ice making device of the present invention can not only simultaneously form ice making and cold water through a simplified structure, but also supply water to the ice making container 10 and the cold water container 20, thereby reducing the size of the ice making mechanism and the occurrence of breakdown. By using the ice making residue that was made in 10) as the cold water tank 20, the cooling function of the cold water tank 20 can be assisted to increase the efficiency of cold water formation, and it is inexpensive by presenting a very simple structure for the production of transparent ice. Transparent ice water purifier can be popularized.

Furthermore, as shown in FIG. 4, the present invention includes a refrigerant inducing member that guides the refrigerant from the first passage 111a of the evaporation tube 111 to the second passage 113s of the ice making nozzle 113. It is preferable to allow the flowing refrigerant to smoothly flow in the second passage of the ice making body 110.

The coolant induction member may be formed as a coolant induction pipe 113A which guides the coolant flowing through the evaporation pipe 111 to the bottom surface of the ice making nozzle 113.

By the refrigerant induction pipe 113A, the refrigerant is smoothly circulated from the evaporation tube 111 to the ice making nozzle 113, thereby facilitating the temperature drop of the ice making water in which the ice making nozzle 113 is locked, and loss of cooling heat of the refrigerant. So that high quality ice is produced quickly.

The refrigerant induction pipe 113A extends toward the bottom surface of the evaporation tube 111, the bent portion, and the ice making nozzle 113 and has a cross-sectional area smaller than the cross-sectional area of the second passage 113s of the ice making nozzle 113. The storage induction part 113c may be connected in turn.

Therefore, the refrigerant for ice making in the ice making device according to the present invention passes through the bent portion and the storage induction part through the evaporation pipe 111 and the inner surface coupling part of the refrigerant induction pipe 113A while the evaporation pipe 111 flows through the ice making nozzle 113. To the bottom of the

In this case, the refrigerant induction pipe (113A) is provided with the coupling portion 113a is opened to the front end side of the ice making nozzle 113, the opening of the coupling portion 113a and the first passage (111a) of the evaporation tube (111) It is formed in the same cross-sectional area and is in contact with the inner surface of the evaporation tube 111, the cross-sectional area becomes narrower toward the bent portion 113b in the direction of the flow of the refrigerant, while the lower end of the storage induction portion 113c is the ice making nozzle A spaced portion 113B spaced apart from the inner bottom surface of 113 is formed.

The refrigerant supplied to the second passage of the ice making nozzle through the spacer 113B stays in the ice making nozzle 113 and flows toward the next ice making nozzle 113 while making ice making.

As described above, the refrigerant for ice making is circulated through each ice making nozzle 113 so that a plurality of ices are simultaneously generated. Therefore, the cross-sectional area of the coupling portion of the ice making nozzle 113 and the refrigerant passage of the evaporation tube 111 are different or different in shape so that the refrigerant not passing through the refrigerant induction pipe 113A is different from the ice making nozzle 113 which has passed. The storage is induced by the refrigerant induction pipe 113A of the ice making nozzle 113, so that the supply and circulation of the refrigerant is evenly performed.

More preferably, the coolant induction pipe 113A has a coupling portion having the same cross-sectional area as the first passage 111a of the evaporation pipe 111, and is directed toward the bent portion 134b (that is, in the flow direction of the coolant). The cross sectional area may be gradually narrowed.

In the above description of the present invention, the ice making mechanism having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and replaced by those skilled in the art. It should be interpreted as falling within the protection scope of the invention.
