The cold and hot water machine illustrated in FIG. 2 includes a cold water tank 70 in which water contained in the plastic bag 10 is moved and stored. Separation plate 20 is installed in the middle of the cold water tank 70, the water located above the separation plate 20 is moved to the hot water tank through a tube installed in the center of the separation plate 20.

On the other hand, a portion of the water located on the upper side of the separation plate 20 is moved by its own weight to the lower side of the separation plate 20 may be cooled by the cooling device.

In this case, the cooling device may include a compressor, an evaporator, an expansion valve, etc., through which refrigerant is circulated so as to supply cold air. In addition, the cold water tank 70 may be provided with a cold water intake coke and the like to supply cold water to the user.

The top cover part 30 is disposed at the upper end of the cold and hot water dispenser, and includes a water guard part 40 mounted at the lower end of the top cover part 30. The water guard unit 40 has a passage 47 for guiding the water contained in the plastic bag 10 into the cold water tank 70. A through hole is provided at an upper side of the passage 47 so that the water moved from the plastic bag 10 may move into the passage 47 and finally move to the cold water tank 70.

Of course, the description of the cold and hot water machine of the above-described form in the specification of the present invention is for convenience of description only, and may be applied to cold and hot water machines of various forms other than the above-described form.

Vinyl bag connection device for cold and hot water according to an embodiment of the present invention is a vinyl bag having a discharge portion 12 for discharging water on the upper side, a lower case (2), the vinyl bag 10 is accommodated, The adapter 100 is coupled to the discharge part 12, and a connection pipe 90 connected to the passage 47 for supplying water to the cold water tank 70 of the cold and hot water machine.

In particular, the connecting pipe 90 is coupled to the adapter 100, and provides a flow path through which the water passing through the discharge portion 12 can be moved to the passage 47. That is, when the adapter 100 is coupled to the discharge part 12, the connection pipe 90 may communicate with the holes formed in the discharge part 12 to move water.

The connecting pipe 90 is a first pipe 92 connected to the adapter 100, a vertical pipe 94 connected to the first pipe 92 and a second pipe extending from the vertical pipe 94 (96).

In this case, the first pipe 92 may be provided to be elevated at a predetermined angle. The plastic bag 10 is deformed as the water contained therein decreases. Therefore, when the portion in which the first tube 92 and the adapter 100 are coupled to descend is lowered, the adapter 100 and the first tube may be reduced even if the plastic bag 10 decreases in internal volume over time. 92, this connection can be maintained.

In particular, the first tube 92 is preferably made of a material capable of bending deformation. When the water of the plastic bag 10 is reduced, the adapter 100 is also lowered, and when the position of the adapter 100 is changed, the first pipe 92 is deformed, so that the adapter 100 and The coupling of the first tube 92 can be maintained continuously.

On the other hand, the vertical pipe 94 is preferably not bent deformation even if the volume of the plastic bag 10 decreases. This is because the coupling state between the adapter 100 and the plastic bag 10 may be maintained by the deformation made in the first pipe 92. Since the vertical pipe 94 does not need to be deformed, it is preferable that the vertical pipe 94 is coupled so as not to move in the lower case 2.

One end of the connecting pipe 90, that is, the second pipe 96 may have a fastening member 98 coupled to the passage 47. The fastening member 98 functions to allow the connection pipe 90 and the passage 47 to be stably coupled. On the other hand, the fastening member 98 may be a separate member formed to engage the shape of the passage 47.

The discharge part 12 has a form of 'I' having a flange formed on the top and the bottom as a whole. Accordingly, the adapter 100 includes an upper protrusion piece positioned above the flange of the upper end of the discharge part 12, and a lower protrusion piece disposed between the flange of the upper end and the flange of the lower end of the discharge part 12. can do. Of course, the adapter 100 may be modified in various forms according to the shape of the discharge part 12.

The plastic bag 10 discharges water to the outside of the plastic bag 10 through the discharge part 12. The discharge part 12 of the plastic bag 10 is always the plastic bag 10. It is located on the upper side of. That is, according to the present invention, since the user does not need to tilt the plastic bag 10 so that the discharge part 12 is moved downward of the plastic bag 10, water is discharged through the discharge part 12. There is no fear of leakage.

Of course, a needle such as a needle may be provided inside the adapter 100 to drill a hole in the discharge part 12.

The lower case 2 may have a form of a basket that can accommodate the plastic bag 10 as a whole. That is, the upper part is open so that the user can rest the plastic bag 10 on the lower case 2. On the other hand, since the side portion and the lower part are sealed, even if the shape of the plastic bag 10 is deformed, the plastic bag 10 can be stably supported in the lower case 2.

A lower end of the lower case 2 may be provided with a plurality of legs (leg) that can be mounted on the upper side of the cold and hot water machine. The legs may support the lower case 2 as a column having three or more. Alternatively, the leg may be modified into a structure that can be seated on the upper case of the cold and hot water machine.

On the other hand, the plastic bag 10 is installed at a position higher than the cold water tank 70 of the cold and hot water machine. This is because the water contained in the plastic bag 10 may be supplied to the cold water tank 70 using the siphon principle. The siphon principle means that the liquid is pushed up into the tube due to the atmospheric pressure acting on the upper liquid surface.

It may also include an upper case 90 for sealing the open upper side of the lower case (2). The upper case 90 may be coupled to an upper side of the lower case 2 to prevent foreign substances from entering the plastic bag 10 and the adapter 100, or the like.

Hereinafter will be described the action of the plastic bag connection device for cold and hot water according to an embodiment of the present invention.

The user installs the plastic bag 10 in the lower case 2 so that the discharge part 12 of the plastic bag 10 is disposed above. In this case, since the plastic bag 10 is filled with water, the user may easily carry the plastic bag 10 rather than the water provided to the plastic bag 10.

The user then connects the fastening member 98 to the passage 47. Of course, the fastening member 98 and the passage 47 may be components that are initially installed to manufacture the cold and hot water machine. If the fastening member 98 is an initially installed component, the user does not need to connect the fastening member 98 and the passage 47 separately. However, when the user needs to replace the plastic bag 10 using all of the water in the plastic bag 10, the fastening member 98 does not separate from the passage 47, and the adapter 100 does not have to be replaced. ) And only the connection of the discharge unit 12.

Subsequently, the user combines the adapter 100 and the discharge part 12 and drills a hole in the discharge part 12 so that a hole is formed in the upper side of the plastic bag 10. In this case, since the discharge part 12 is disposed above the plastic bag 10, there is no fear that water may leak through the discharge part 12.

The user increases or decreases the pressure in the water in the plastic bag 10 by using the adapter 100, so that a part of the water in the plastic bag 10 is raised to the upper end of the discharge part 12, and the connection is performed. May be drawn into the tube 90. Then, the passage 47 is reached through the connecting pipe 90. In this process, water may be continuously supplied to the passage 47 due to the principle of siphon. That is, the water contained in the plastic bag 10 is raised through the discharge portion 12, and then descends while passing through the connecting pipe 90.

At this time, the plastic bag 10 is reduced in overall shape as the water is discharged. Similarly, as the volume of the plastic bag 10 decreases, the height of the discharge part 12 also decreases. This is because the plastic bag 10 may be pressurized due to the weight of the adapter 100 coupled to the discharge part 12 as well as the discharge part 12. However, since the lower case 2 receives and supports the plastic bag 10, the position of the discharge part 12 may be fixed to the upper side of the plastic bag 10.

That is, even if the volume of the plastic bag 10 decreases, the lower end of the discharge part 12 reaches the level of water contained in the plastic bag 10, and thus, the passage 47 through the connecting pipe 90. Water can be supplied continuously.

In particular, when the volume of the plastic bag 10 is reduced, the position of the discharge part 12 as well as the adapter 100 is lowered, and the first tube 92 may be modified to correspond thereto. Because of this, the discharge portion 12 and the adapter 100 can be maintained a continuous coupling.

In this case, the upper case 60 may press the plastic bag 10 evenly. In addition, even when the volume of the plastic bag 10 is reduced, since the upper case 60 may pressurize the upper surface of the plastic bag 10 evenly, water contained in the plastic bag 10 may be smoothly discharged. To help.

In this embodiment, the plastic bag 10 is continuously pressed by the upper case 60. Therefore, since the inside of the plastic bag 10 is subjected to a greater pressure as compared to the absence of the upper case 60, water is temporarily supplied to the adapter 100 while water is reduced in the inside of the plastic bag 10. Uninterrupted interruptions do not occur. Because the upper case 60 has a predetermined weight, when the upper case 60 is seated on the plastic bag 10, the plastic bag 10 is initially pressed to the plastic bag 10. This is because the received water may rise to the discharge part 12.

Meanwhile, the pressing plate 62 presses the upper part of the plastic bag 10 by the elastic force of the elastic member 64 in the upper case 60. Accordingly, the water of the plastic bag 10 may be moved to the connection pipe 90 through the discharge part 12.

The length of the elastic member 64 is changed as the volume of the plastic bag 10 is changed, thereby continuously pressing the plastic bag 10. As water is discharged to the plastic bag 10 and the size of the plastic bag 10 decreases, the compressive force applied to the elastic member 64 decreases, so that the length of the elastic member 64 increases. That is, even if the size of the plastic bag 10 is reduced, the pressure plate 62 may continuously press the plastic bag 10, so that water is discharged to the discharge part 12 through the plastic bag 10. As it rises, water can be stably supplied to the passage 47.

Since the guide unit 150 includes the first check valve 154 and the second check valve 162, water drawn out from the plastic bag 10 is introduced into the plastic bag 10 again. Can be prevented.

The guide tube 160 may be provided with an extension tube 164 for guiding the water introduced into the guide tube 160. The extension tube 164 may perform a function of providing a flow path for extending the guide tube 160.

The guide part 150 includes a fixing lever 166 for fixing the needle 156 by moving downward. The fixing lever 166 allows the user to grip the finger at both ends so that the fixing lever 166 can be easily rotated or moved up and down.

The fixing lever 166 includes a fixing protrusion 167 seated on an upper surface of the fixing piece 153 provided on the body 152. The fixing piece 153 is provided below the body 152, and a plurality of fixing pieces intermittently protrude along the outer circumferential surface of the body 152.

Similarly, the fixing protrusion 167 is intermittently formed to protrude inward along the hollow formed inside the fixing lever 166. Therefore, the inside of the fixing lever 166 is inserted into the needle 156, the fixing lever 166 in the state where the fixing projection 167 is disposed in the empty space where the fixing piece 153 is not provided. ) Can be rotated after it is moved upwards. The fixing lever 166 and the body 152 may be vertically restrained by the fixing piece 153 and the fixing protrusion 167. This is because the fixing piece 153 is fastened to the lower surface of the fixing protrusion 167.

The fastening part 180 may include a leg 182 fitted to an upper side of the discharge part 12. The legs 182 are formed in two, and the legs 182 have a shape bent to have a predetermined space on the upper side. That is, the leg 182 has a shape of 'b' as a whole, so that the upper side of the discharge portion 12 can be fitted to the upper surface of the leg 182.

In addition, the hollow 184 is formed at the center of the fastening part 180, so that the movement path of the needle 156 may be secured when the needle 156 moves downward.

11 to 14 is a view showing the operation of the adapter of the plastic bag connection device for cold and hot water. 11 to 14, the operation of the present invention will be described.

For reference, FIGS. 11 to 14 show a state in which the discharge part 12 of the plastic bag 10 is omitted in order to simplify the drawing. However, a description will be given on the assumption that the upper side of the discharge portion 12 is fitted to the upper surface of the leg 182.

In the state of FIG. 11, since the body 152 is raised upward, the body 152 is exposed to the upper side of the housing 130. In the state of FIG. 11, the leg 182 may be inserted into the discharge part 12, so that the fastening part 180 and the discharge part 12 may be coupled to each other.

As shown in FIG. 12, when the user descends the fixing lever 166, the fixing lever 166 may descend along the vertical groove 134.

At this time, since the fixing lever 166 and the body 152 are coupled to restrain the vertical movement, the body 152 is also lowered together. Therefore, the needle 156 provided in the body 152 is also lowered, and a hole penetrating the vinyl of the plastic bag located in the discharge part 12 may be formed.

When the user rotates the fixed lever 166 as shown in FIG. 13, since the fixed lever 166 and the body 152 may be freely rotated, the body 152 is not rotated but is stopped. Maintain state. On the other hand, the fixing lever 166 is rotated along the horizontal groove 136.

Since one end of the horizontal groove 136 is not formed with a vertical groove, the fixing lever 166 does not rise unless additional external force is applied and is fixed in a stopped state.

Accordingly, the body 152 is also lowered by the position where the fixing lever 166 is lowered, so that the needle 156 may continuously maintain contact with water contained in the plastic bag 10. When the water contained in the plastic bag 10 decreases, the needle 156 is soaked in water because the plastic bag adapter 100 descends due to the weight of the discharge part 12 and the plastic bag adapter 100. There is a high probability of losing.

As shown in FIG. 14, in the state of FIG. 13, after the user touches three fingers with the button 112 and the protruding piece 132, the user narrows the distance between the button 112 and the protruding piece 132. The pressure inside the plastic bag 10 may be increased.

On the other hand, when the user releases the finger on the button 112 and the protruding piece 132, the pressure between the button 112 and the protruding piece 132 increases and the pressure inside the plastic bag 10 may decrease. have. That is, the user may generate a pressure change to the water inside the plastic bag 10 in a state in which the hand does not touch the plastic bag 10 so that the water flows into the guide tube 160.

15 to 18 are cross-sectional views showing the operating state of the adapter of the plastic bag connection device for cold and hot water. Hereinafter, with reference to Figs. 15 to 18, the internal state of the present invention will be described.

In the state shown in FIG. 15, the fastening part 180 of the adapter 100 is coupled to the discharge part 12. At this time, since the needle 156 is raised and does not penetrate the discharge part 12, no hole is formed in the discharge part 12.

Meanwhile, the guide part 150 and the pumping part 110 may be disposed at a position higher than the discharge part 12. This is because the discharge part 12 is made of a rigid plastic material compared to the plastic bag 10, and the discharge part 12 is disposed above the plastic bag 10, the plastic bag adapter 100 This is because is coupled to the discharge portion (12).

In the state illustrated in FIG. 16, the needle 156 is lowered by the user lowering the fixing lever 166 so that the needle 156 penetrates the discharge part 12. At this time, the needle 156 is immersed in the water contained in the plastic bag (10). Although not clearly shown in FIG. 16, when the fixing lever 166 is rotated, the needle 156 does not rise again but is fixed in the form shown in FIG. 16.

Subsequently, when the water in the plastic bag 10 is continuously supplied to the hot and cold water through the adapter 100, the plastic bag 10 is broken because the water contained in the plastic bag 10 is stalked. Of course, in the state of Figure 16, the user presses the button 112, it is necessary to initially implement the state in which the water is moved to the guide tube (160) (the related operation will be described in Figure 18).

In this case, when the needle 156 temporarily deviates from the water contained in the plastic bag 10, the water may not be supplied to the guide tube 160. This is because the siphoning principle stops moving the water. This water supply interruption phenomenon may occur frequently when water is left in the plastic bag 10 in approximately 1 Liter. This is because the plastic bag 10 does not have a predetermined shape, and when there is a small amount of water, water may be collected at another position so that the needle 156 may not be sufficiently immersed in water. However, since the embodiments of FIGS. 3 and 4 have an additional configuration for pressurizing the plastic bag 10, the risk of stopping supply of water even if the water contained in the plastic bag 10 is reduced is reduced. Less likely.

In this case, as shown in FIG. 18, the user may press the button 112 so that the water dipped in the needle 156 may be raised to the guide tube 160. That is, the pumping unit 110 is initially installed in the plastic bag 10, or when the falling of the water contained in the plastic bag 10 is stopped, in the plastic bag 10 The siphon principle can be used to provide pressure to lower the received water to hot and cold water.

When the user repeatedly presses the button 112 and releases the pressure, since a volume change of the case 124 of the pressing piece 120 occurs, water may be guided to the guide tube 160. have.

On the other hand, after the user presses the button 112, when the force is removed, the compression spring 118 is returned to the circular by the restoring force. At this time, the pressing piece 120 may also be returned to the circular shape by a force tensioned by the compression spring 118. This is because the compression spring 118 maintains contact with a plurality of surfaces of the case 124 of the pressing piece 120, in particular, the plurality of pleats 126.

That is, since the compression spring 118 is not spaced apart from the case 124 and the pleats 126, and is in contact with the case 124 and the pleats 126, the compression spring 118 is compressed. And the deformation according to the tension may be transmitted to the pressure piece 120 substantially the same.

In particular, the pressure piece 120 prevents the water guided from the plastic bag 10 to the guide part 150 penetrates the inside of the pumping part 110 and leaks to the button 112, that is, the outside. can do. Since the pressing piece 120 is a component made of a silicon material having a space therein, water does not penetrate the pressing piece 120, and stays only under the pressing piece 120. In particular, since the flange 122 is provided on the pressing piece 120, it is possible to prevent the water from moving to the upper side of the flange 122 as well as the pressure change applied to the water.

On the other hand, since the first check valve 154 and the second check valve 162 are provided, the water raised by the pressing piece 120 does not flow back to the plastic bag 10. For example, when the needle 156 temporarily leaves the water of the plastic bag 10, the water of the guide tube 160 may descend into the plastic bag 10 by its own weight. In this case, the water contained in the plastic bag 10 may be contaminated while mixing with the water contained in the plastic bag 10. In the present invention, since the two check valves are provided, the water may be prevented from flowing back. .

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.
