1 to 10, the drinking water supply device according to the present invention may be composed of a water purifier with filtration means, a cold / hot water heater without filtration means,

An ice producing unit including ice making means 20 for generating ice and an ice storage unit 32 and a cold water supplying unit 31 for storing cold water are structurally provided together in one reservoir 30,

An icemaker 20 including an ice tray 10 and an icemaker 21, a reservoir 30 having a cold water supply unit 31 and an ice reservoir 32, a residual water tray 40, Means (50) and ice-making water circulation means (60).

Although not shown in the drawing, the drinking water supply device includes a cold water line connecting [filter portion-cold water supply portion-discharge member], hot water line connecting [filter portion-hot water storage portion-discharge member] , And an ice line connecting the [ice reservoir - exhaust member], each exhaust member being independently configured for cold water, hot water, purified water, and ice discharge, All of which can be integrated.

The raw water supply unit W for supplying water to the filter unit F may be connected to a common indoor water pipe or the like, or may be a water tank using other purified water.

In the edible water supplying apparatus of the present invention, the supply, the circulation, the water to be discharged, and the water to be ice-made by ice are all filtered and purified so that the essence of the water is the same but the deicing water, Water, cold water, etc., can be described in the respective characteristic constructions for convenience in accordance with the principle of production of water, the purpose of use, and the like, and can be explained without any distinction for convenience.

First, the ice making device 20 of the present invention includes an ice-making container 10 filled with ice-making water, an evaporation pipe 22 through which the refrigerant flows, and ice- And an ice making body 21 having a plurality of ice making nozzles 23 to be performed.

The ice making body 21 is formed such that the evaporation pipe 22 is formed in a U shape and the first and second circulation sections 22A and 22B through which the refrigerant circulates are connected to the refrigerant supply pipe 111A and the refrigerant discharge pipe And a plurality of ice-making nozzles 23 protruding downward from the first and second circulation units 22A and 22B are connected to the first and second circulation units 22A and 22B.

8 and 9, the ice-making device 20 includes a compressor 120, a condenser 130, a converter 140, and other devices including an evaporator, which are used in a normal freezer, a water purifier, The refrigerant is supplied and circulated from the components to the ice-making body 21,

This is a comparatively simple configuration of a commercial ice water purifier and can be sufficiently predicted by a person skilled in the art, so that specific operating principle and detailed structure using it will be omitted for convenience.

The compressor 120 for the compression stroke roughly forms a high-temperature and high-pressure refrigerant which is easy to be liquefied at room temperature (for example, a room temperature (30 ° C.), a low-pressure gas (0 kg / cm 2), a high temperature (80 to 120 ° C.) High-pressure gasification (8 to 12 kg / cm 2)),

In order to evaporate the active refrigerant, a low-pressure refrigerant is sucked into the compressor 120 and then compressed by a piston in the cylinder to be easily liquefied.

The condenser 130 for the condensation stroke then converts the high temperature and high pressure gas refrigerant into a high temperature and high pressure liquid such as a high temperature (80 to 120 ° C), a high pressure gas (8 to 12 kg / cm 2) ℃) v High pressure liquidization (8 ~ 12kg / ㎠)),

It is a heat exchanger that cools and condenses compressed gas.

The converter 140 for the expansion stroke (capillary) makes the refrigerant at a low pressure (for example, at room temperature (40 to 60 ° C), high pressure liquid (8 to 12 kg / cm 2) Liquidation (0 kg / cm 2)),

Before sending the liquefied high-pressure refrigerant to the evaporator, the pressure reducing action is performed to lower the pressure to a state where evaporation is easy, and the flow rate of the refrigerant liquid is controlled.

Finally, the evaporator for the evaporation stroke changes the refrigerant from liquid to gas and takes heat (eg low temperature (-30 ℃) ㅇ low pressure liquid (0kg / ㎠) ⇒ low temperature (-30 ℃) ㅇ low pressure gasification / Cm2)),

The low pressure refrigerant inside the evaporator (cooler) takes heat away from the air around the cooler by the latent heat of evaporation of the refrigerant during vaporization.

The ice making unit of the ice making unit includes a compressor 120, a condenser 130, a converter 140, and an evaporator, which are connected to each other so that known refrigerants are circulated to form a cooling cycle.

In particular, the edible water supply device according to the present invention comprises a single compressor (compressor) 120 (for convenience, and in some commercial advertising terms, the configuration of the cooling cycle associated with the other condenser 130 and the transducer 140) One evaporator is constituted by the ice making means 20 and the other evaporator constitutes the cold water forming means of the cold water supplying section 31. In this case,

The ice making device 20 of the present invention is a device in which the ice making nozzle 23 of the ice making body 21 (the evaporating tube 22 and the ice making nozzle 23 corresponds to the evaporator in the cooling section constituting the normal cooling cycle) The hot gas of high temperature and high pressure is discharged from the ice making line 150 branched from the piping connecting the compressor 120 and the condenser 130 when the valve is opened The contact surface of the ice (I), which is supplied to the ice making body (21) and is in contact with the ice making nozzle (23), is instantaneously melted to perform ice making.

The connection point between the ice making line 150 and the ice making body 21 is connected to the connecting portion of the coolant supplying portion 111A connected to the converter 140 and the connecting portion of the ice tray 21 or the connecting portion between the coolant discharging portion 111B and the ice tray 21, Or other portion, and in this case, a suitable connection point can be selected in consideration of the deicing efficiency, ice-making and cold water efficiency.

The ice making cylinder 10 includes a rotary shaft 11 coupled to both ends thereof hinged to the inner surface of the storage container 30 so as to be rotatable and is detachable from the ice making nozzle 23, The dropped ice is dropped and stored in the ice storage section 32 via the projecting piece 12 in accordance with rotation of the ice-making cylinder 10 in one direction.

At this time, the remaining water (ice-making water) used for ice making in the ice-making cylinder 10 is discharged to the lower portion together with ice when the ice-making cylinder 10 rotates in one direction, The ice water is dropped and stored in the supply part 31 and the remaining part is dropped and stored with the ice in the ice storage part 32 partitioned into the cold water supply part 31 and the partition wall 35.

If necessary, the ice cubes scraped from the ice-making nozzle 23 may be discharged to the cold water supply unit 31 together with the ice-making residue of the ice-making cylinder 10 to form cold water. However,

This method is not preferable in terms of cold water generation efficiency as well as being a major factor for slowing ice production, especially in the case of using a lot of ice and cold water as in the summer.

In order to improve this, in the present invention, the cold water forming means (cooling pipe 24) immersed in the cold water of the cold water supply unit 31 in the ice making body 21 is provided so as to be able to maintain and store the cold water at an appropriate temperature, And connected to the connection pipe 24a.

 Furthermore, in the present invention, apart from the ice making means 20 for ice making, the embodiment in which the cooling portion constituting the cooling cycle is introduced only for the cold water supply portion for generating the direct cold water is not excluded.

Nevertheless, in the drawings of the present specification, the cooling pipe 24 as the cold water forming means and the ice-making body 21 are connected to each other so that the ice-making unit 20 and the cold water supply unit 31 can be described together.

The cooling pipe 24 connected to the ice making body 21 is connected to the compressor 120 so as to recover the refrigerant passing through the coolant supply unit 111A or the ice making nozzle 23 connected to the converter 140 of the ice making unit 20 May be an extension of the pipe constituting the refrigerant discharge portion 111B,

Further, in order to give priority to the efficiency of ice production, it is more preferable that the cooling pipe 24 is an extension of the pipe constituting the coolant discharge portion 111B.

The arrangement and length of the cooling pipe 24 may be variously selected as needed.

The term "the cooling pipe 24 is connected to the evaporator" in the description of the present specification and claims as "the evaporator of the cooling section and the cooling pipe 24 connected to the compressor 120" means that the converter 140 (capillary) And the cooling pipe 24 itself is an evaporator, and the cooling pipe 24 is connected to the cooling pipe 24 in the form of a part of the evaporator performing the evaporation stroke,

In this extension line, the expression "the evaporator tube 22 of the ice-making device 20 is connected to the evaporator of the cooling section" corresponds to the expression of the same intention.

Next, the cooling piping 24 and the cold water supply unit 31 connected to the compressor 120 will be described as the cold water supply unit provided in the cold water supply unit 31. FIG.

Further, if necessary, the cooling pipe 24 may be in contact with or spaced from the cold water pipe 31A,

The cold water pipe 31A and the cooling pipe 24 are 'adjacent arranged'

The meaning that any one of the cold water pipe 31A and the cooling pipe 24 'surrounds' another member is a concept encompassing these two cases.

Further, an ice grille (Tg) in the form of a mesh net is provided at the lower portion of the screw member 33 so that only ice can be passed while ice is caught.

An ice discharge door (not shown) is provided on the ice discharge port 32a to open and close the ice discharge port 32a in cooperation with the screw member 33,

When the screw member (33) is operated, the door is opened and the ice is carried on the sliding part and finally discharged through the ice discharging cock.

The ice making body 21 is a kind of evaporator in which the low temperature and low pressure refrigerant converted through the compressor 120, the condenser 130 and the converter 140 constituting the cooling cycle flows,

The ice making body 21 includes an evaporating pipe 22 and an ice making nozzle 23. The ice making nozzle 23 is a nose-shaped protrusion formed by protruding from the evaporating pipe 22, A plurality of nozzles 23 may be collectively known.

As the liquid refrigerant passes through the ice-making nozzle 23, ice is produced around the ice-making nozzle 23 by cooling the ice-making water in the ice-making cylinder 10.

Then, hot gas is blown into the ice making nozzle 23 and ice is removed from the ice making nozzle 23 while the contact surface between the ice making nozzle 23 and ice melts.

The ice cubes are removed from the ice-making cylinder 10 due to their own weight as the ice-making cylinder 10 rotates in one direction and are transferred from the ice-storing portion 32 through the partition wall 35 to the screw member 33, And is discharged to the ice discharge port 32a and supplied to the user.

At this time, in the present invention, the remaining ice used in the ice making process may be directly transferred to the cold water supply unit 31, or may be transferred to the ice storage unit 32 and then drained to the cold water supply unit 31 to be used as cold water.

That is, according to the present invention, simultaneous supply of ice and cold water is possible by separating and discharging the ice-making residual water and ice at the same time by utilizing the rotating ice-making cylinder 10 and storing the ice- It becomes.

To this end, the ice-making cylinder 10 is rotatably coupled to the reservoir 30,

A protruding piece 12 that forms a spacing 12a with a narrower interval than ice formed between the ice cubes 10 and the partition wall 35 during rotation of the ice-making container 10 in one direction is disposed at one end of the ice- Respectively,

During rotation of the ice-making cylinder 10 in one direction, a part of the ice and ice-making residual water is discharged to the ice storage portion 32 through the protruding piece 12.

The remaining part of the ice-making water may be discharged to the cold water supply unit 31 through the spacing part 12a when the ice-making cylinder 10 is rotated in one direction as necessary.

Therefore, in the unrotated state (return) of the ice-making cylinder 10, the ice-making water stays in the ice-making cylinder 10 (more precisely, the supply and discharge are continuously performed and the description thereof will be described later) And,

When the ice is dehydrated after the completion of ice-making, the ice-making tray 10 is rotated downward in the direction of one side of the ice-making tray 10, and the ice-making residue and the ice I are discharged together,

At this time, as the projecting piece 12 swings close to the partition wall 35, the ice and ice making water rides over the partition wall 35 and drops into the ice storage part 31. As a result, Is supplied again to the ice-making cylinder (10) through the supply means (50) to be used as deicing water,

If the swinging piece 12 passes through the partition 35 and swing displacement is completed as necessary, the remaining ice-making residue falls through the separating part 12a into the cold water supply part and is stored and used as cold water.

In addition, some ice may get caught in the separating part 12a and fall into the ice storage part 32 and may not be stored. However, such ice is prevented from being separated from the separating part 12a And the ice is poured into the ice storage part 32. The ice-

Therefore, the ice-making residual water discharged to the ice storage section 32 is supplied again to the ice-making tray 10 in the state of being stored in the residual tray 40, and is utilized as de-iced water, thereby shortening the ice- You can,

If necessary, the cold water supply unit 31 can cool and cool water while mixing the ice making water cooled to close to 0 캜 separately from the ice making means, thereby improving the cold water forming efficiency.

That is, since the ice-making residual water itself is cooled by the ice-making nozzle 23 to close to 0 ° C, it is delivered to the cold water supply unit 31 and mixed with raw water, so that the cold water cooling and the cold water replenishment are natural,

As the cooled ice-making water is used as de-icing water, quick deicing becomes possible as compared with the case where the raw water at room temperature is cooled to be de-iced.

At this time, the cold water supply unit 31 is provided with a sensor for sensing the temperature and the water level of the stored cold water to control the supply of ice-making residual water by the ice-making cylinder 10 or the supply of purified water through the raw water supply unit, .

The residual water tray 40 stores the cooling water discharged from the ice storage 32,

And is located directly below the ice storage part 32 so as to be connected to the discharge pipe 32b formed at the bottom of the ice storage part 32. [

Here, the cooling water discharged from the ice storage section 32 is not only the ice-making residual water transferred from the ice-making cylinder 10 to the ice storage section 32, but also the water in which the ice stored in the ice storage section 32 is partially melted, Is a concept that includes numbers.

That is, the ice-making residual water discharged to the ice storage part 32 together with the ice is discharged to and stored in the residual water tray 40 through the discharge pipe 32b, and the ice stored in the ice storage part 32 melts, The water is also discharged through the discharge pipe 32b to the residual water tray 40 and stored.

Therefore, the present invention utilizes the cooling water cooled to 0 deg. C as the deicing water, so that the ice making time of the ice can be shortened.

In particular, in the case of impurities contained in the filtered purified water, ice is not frozen together with ice, but remains in the ice-making cylinder 10 due to the freezing process characteristic of ice. Therefore, if the remaining ice- The cold water and the ice-making water can be kept cleaner than the purified water, and the hygienic properties of the cold water and the ice can be improved.

As the ice is repeatedly iced, the amount of ice-making water is larger than that of ice-making water used. Therefore, it is possible to prevent the overflow of the cooling water stored in the residual water tray 40 (which may cause a short circuit, electric shock or fire). , And to prevent the inhibition of hygiene by cooling water,

If necessary, the drain pipe 41 is preferably provided with a solenoid valve at the front end (or the rear end) of the drain pump 43 so as to obtain a backflow prevention effect.

In addition, the residual water tray 40 and the supply pipe 52 preferably include a cold / warm-up function to prevent the temperature of the cooling water from rising,

Of course, even if only the cooling water in the residual water tray 40 is circulated, cooling by the ice-making means 20 is continued, so that circulation or replenishment of de-iced water using the three-way valves 62a and 63a is only required.

And reference numerals 15 and 16 denote ice making water circulation nozzles connected to the circulation pipes 62 and 63 so that the circulation nozzles 15 and 16 are filled in the ice making cylinder 10 by the circulation pump 61 And the circulation of the iced water is performed by sucking and discharging the iced water.
