The ice making device of the embodiment of the invention can be used independently, and can also be arranged on various devices such as a water purifier or a water dispenser for use. However, the following description will be focused on a case where the ice making device is attached to the water purifier.
Fig. 1 is a side sectional view of a water purifier having an ice making device according to a first embodiment of the present invention, fig. 2 is a front sectional view illustrating a water receiving tank of the water purifier having the ice making device according to the first embodiment of the present invention when ice is made, and fig. 3 is a front sectional view illustrating the water receiving tank of the water purifier having the ice making device according to the first embodiment of the present invention when ice is removed.
Referring to fig. 1 to 3, a water purifier 10 having an ice making device 200 according to a first embodiment of the present invention may include: a housing 100; a purified water tank (not shown) for storing purified water; a cold water tank (not shown) for storing water supplied from a clean water tank (not shown) in a cooled state; a hot water tank (not shown) for heating water supplied from a clean water tank (not shown) to a predetermined temperature and storing the heated water; an ice making device 200 capable of cooling water supplied from a cold water tank (not shown) to prepare cold water or ice 600; an ice bank 500 for storing ice 600; a grill (grill) to move the ice 600 prepared by the ice-making device 200 toward the ice bank 500.
The water purification tank (not shown) may store water purified by various water purification methods, for example, an activated carbon adsorption method, a filtration method, an Ultra Filter (UF), a Nano Filter (NF), a Reverse Osmosis (RO), and the like, and selectively supply the stored water to a cold water tank (not shown) or a hot water tank (not shown). The water supplied from the pure water tank (not shown) to the cold water tank (not shown) or the hot water tank (not shown) may be controlled by an electromagnetic valve. That is, when the water level of the cold water tank (not shown) or the hot water tank (not shown) drops below a predetermined value, the electromagnetic valve is opened, and the purified water stored in the purified water tank (not shown) is supplied to the cold water tank (not shown) or the hot water tank (not shown). In the case of a drinking fountain used by installing a drinking water tank, the above-described clean water tank (not shown) may be replaced with the drinking water tank, and when raw water such as tap water is directly used, the clean water tank (not shown) may be omitted and the raw water may be directly supplied to the cold water tank (not shown).
The cold water tank (not shown) stores cold water, and can supply cold water to the ice making device 200 through a circulation pump and a supply flow path. Cold water 230 supplied from a cold water tank (not shown) to water receiving tub 220 of ice making device 200 is frozen by an evaporator to form ice 600.
The hot water tank (not shown) can heat water supplied from the clean water tank (not shown) by a general heating means (not shown) such as a hot wire (hot wire), and the water is heated to a predetermined temperature and stored. The hot water stored in the hot water tank (not shown) may be supplied to the user through the intake port.
The ice bank 500 may be used to store ice prepared by the ice-making device 200. The ice bank 500 is disposed at a lower side with respect to the ice-making device 200, and the ice made by the ice-making device 200 drops by gravity, i.e., the de-iced ice drops by its own weight, and slides along the grating to move to the ice bank 500.
The ice bank 500 is provided with a screw 400, the screw 400 transfers the stored ice 600 to the ice inlet 110 side, and the screw 400 is coupled with a motor 410 for rotating the screw 400. However, the ice 600 is not necessarily taken out using the screw 400.
The grill 300 is positioned at the lower portion of the water receiving tub 220, and the grill 300 may be formed with a perforation 310 having a diameter smaller than that of the ice 600. That is, the ice 600, which has been de-iced after being prepared in the ice making device 200, cannot pass through the perforation 310, and thus moves along the inclined surface of the grill 300 to flow into the ice bank 500, and the ice 600 flowing into and stored in the ice bank 500 may be supplied to the user through the ice taking port 110. In addition, water that is not made into ice in the ice making device 200 and drips may be guided into the cold water tank (not shown) through the perforation 310.
Fig. 4 is a sectional view of a portion a of fig. 1, and fig. 5 is a partially cut-away perspective view of a water purifier having an ice making device according to a first embodiment of the present invention, after a clutch and a coupler are separated.
Referring to fig. 1 to 5, an ice-making device 200 according to a first embodiment of the present invention includes: a water supply unit 210, a water receiving tank 220, an evaporator 230, a rotation unit 240, a coupler (coupler)250, and a clutch (clutch) 260.
In order to make ice, the water supply unit 210 may supply water to the water receiving tank 220 in various ways. For example, water may be supplied to the water receiving tank 220 through a pipe or the like connected to an external water supply source, water may be supplied from a pure water tank directly through various flow paths or pipes, or water may be supplied from a cold water tank to the water receiving tank 220. The water supplied from the water supply unit 210 to the water receiving tank 220 is frozen by the evaporator 230 immersed in the water receiving tank 220. Here, the water supply unit 210 shown in fig. 1 is only an example.
In order to make the ice 600, the water receiving tank 220 stores water supplied from the water supply unit 210. The water receiving tank 220 may have various shapes in which a storage space is formed so as to store water. The water receiving tub 220 is provided at an upper portion of the grill 300 and can be rotated by a predetermined range of angles by the rotating unit 240.
The evaporator 230 is immersed in the water stored in the water receiving tank 220 to cool the water. The evaporator 230 may include, for example, a refrigerant flow pipe in which a refrigerant flows and cools the water stored in the water tank 220 by a general refrigeration cycle system configured by a compressor, a condenser, and an expander together. In addition, heat may be supplied to the evaporator 230 in various ways to enable the ice 600 frozen by the evaporator 230 to be de-iced from the evaporator 230. For example, an electric heater may be provided on the evaporator 230 via an electric wire, and the ice 600 may be de-iced by melting a portion of the ice 600 by heat supplied to the evaporator 230 by the electric heater.
The rotation unit 240 is coupled to the water receiving tank 220 to selectively rotate the water receiving tank 220. The rotation unit 240 may include various different kinds of motors to enable the water receiving tub 220 to rotate at a predetermined angle. In addition, the rotation unit 240 may be combined with a sensor, and the rotation angle may be adjusted by a sensor (not shown). When ice 600 is prepared, water receiving tub 220 maintains a state in which water can be stored (see fig. 2), and when ice making is completed and ice is removed, water receiving tub 220 is rotated by rotation unit 240 (see fig. 3), and ice 600, a part of which is melted by the electric heater, falls to grill 300. In addition, the cold water drops to the cold water tank through the perforation 310 of the grill 300, and the ice 600 may move along the inclined surface of the grill 300 and flow into the ice bank 500.
In addition, when the water stored in the water receiving tank 220 is cooled by the ice making device 200, the water receiving tank 220 and the coupling 250 are also cooled and frozen. At this time, when the rotation unit 240 rotates, the coupler 250 or the water receiving tub 220 may be damaged. To prevent this, when the water receiving tank 220 or the coupling 250 is frozen due to cooling, that is, when the water receiving tank 220 or the coupling 250 is frozen, the clutch 260 is pushed away from the coupling 250 to idle. This will be explained below.
Referring to fig. 4 and 5, the coupling 250 is coupled to one side of the water receiving tub 220, connected to the clutch 260 coupled to the rotation unit 240, and rotated together with the water receiving tub 220 by receiving a rotational force of the rotation unit 240 through the clutch 260.
The clutch 260 is coupled to the rotation unit 240, and when the rotation unit 240 is a motor, for example, the clutch 260 is coupled to the motor shaft 241 and rotates together with the rotation unit 240. The clutch 260 is connected to the coupling 250, and transmits the rotational force of the rotating unit 240 to the water receiving tub 220 through the coupling 250, or releases the transmission of the rotational force. The clutch 260 is formed with a gear for coupling with a gear of the coupler 250, which will be described in detail later.
The elastic unit 270 is disposed between the clutch 260 and the rotating unit 240 to provide an elastic force. Here, the elastic unit 270 may use various mechanisms or devices having elasticity, and may be, for example, a coil spring.
Referring to fig. 5, the interior of the central hole 254 of the insertion portion 253 of the coupling 250 may be formed with a first gear transmission 255. The first gear driver 255 may be formed in various ways, for example, may be formed to protrude from the central portion 257 and be formed radially from the protruding central portion 257 to the rim 258. At this time, each gear tooth 256 may be formed to be inclined from the central portion 257 toward the edge 258. That is, it may have a shape in which the center portion 257 protrudes and the height becomes lower as it gets closer to the edge 258.
Further, the clutch 260 may be formed with a second gear transmission 261 corresponding to the first gear transmission to be able to be combined with the first gear transmission 255. The second gear transmission 261 may be formed in various ways, for example, may be formed with a central portion 267 that is concave and radially formed from the concave central portion 267 to an edge 268. At this time, each gear tooth 266 may be formed to be inclined from the central portion 267 toward the edge 268. That is, it may have a shape in which the center portion 267 is concave and the height is higher as it gets closer to the edge 268.
Further, each of the gear teeth 256 of the first gear transmission 255 may be formed into a smooth curved surface so that the engagement with the second gear transmission 261 can be released when necessary. Each of the gear teeth 266 of the second gear transmission 261 may be formed as a smooth curved surface to enable disengagement with the first gear transmission 255 when required. This is explained as follows. Each gear tooth 256 formed at the first gear transmission 255 of the coupling 250 and each gear tooth 266 formed at the second gear transmission 261 of the clutch 260 are engaged with each other to rotate, so that the clutch 260 can transmit the rotational force from the rotation unit 240 to the water receiving tub 220 through the coupling 250. Thereby, the water receiving tub 220 may be rotated at a predetermined angle. Here, as described above, when the water stored in the water receiving tank 220 is cooled and the water receiving tank 220 or the coupling 250 is frozen, the clutch 260 and the rotating unit 240 are caused to rotate idly with respect to the water receiving tank 220 or the coupling 250 in order to prevent the water receiving tank 220 or the coupling 250 from being damaged. That is, since the coupling 250 is frozen and fixed, the inclined portion 269 of the gear teeth 266 formed in the second gear transmission 261 of the clutch 260 moves along the inclined portion 259 of the gear teeth 256 formed in the first gear transmission 255 of the coupling 250, and at this time, since the elastic unit 270 is provided between the clutch 260 and the rotating unit 240, the clutch 260 is pushed from the coupling 250 to the rotating unit 240 side, only the clutch 260 is rotated, and the coupling 250 maintains the fixed state. At this time, the respective gear teeth 256 and 266 of the first and second gear transmissions 255 and 261 may be formed in a smooth curved surface so that the inclined portions 269 of the gear teeth 266 of the second gear transmission 261 can easily move along the inclined portions 259 of the gear teeth 256 of the first gear transmission 255.
As such, when the water receiving tub 220 or the coupling 250 is frozen, the clutch 260 is pushed from the coupling 250 to the rotation unit 240 side to rotate and idle, and thus the rotational force of the rotation unit 240 is not transmitted to the coupling 250, whereby the water receiving tub 220 or the coupling 250 can be prevented from being damaged even if the water receiving tub 220 or the coupling 250 is frozen.
Fig. 6 is a perspective view of a water purifier having an ice making device according to a first embodiment of the present invention, in which a water receiving tank is coupled to a water receiving tank supporting member. Fig. 7A is a sectional view of the water receiving tub of fig. 6 in a state of being coupled to the water receiving tub supporting member, and fig. 7B is a sectional view of the water receiving tub of fig. 6 in a state of being separated from the water receiving tub supporting member.
As described above, one side of the water receiving tank 220 is coupled with the rotating unit 240 through the coupling 250 and the clutch 260. The other side of the water receiving tub 220 is coupled to and supported by a water receiving tub supporting member 280a provided inside the main body.
Referring to fig. 6, 7A and 7B, a center hole 281 is formed in the center of the water receiving tray supporting member 280a, and an opening part 282 is formed at one side. The second connection shaft 225 of the water receiving tub 220 is attached and detached by an opening part 282 formed in the water receiving tub supporting member 280 a. Here, the water receiving tank supporting member 280a may be made of plastic or the like by injection molding so as to have elasticity. That is, when the second connection shaft 225 of the other side of the water receiving tub 220 is contacted with the water receiving tub supporting member 280a through the opening part 282 of the water receiving tub supporting member 280a and pressed, the water receiving tub supporting member 280a is elastically deformed to be expanded, and the second connection shaft 225 of the water receiving tub 220 is introduced and seated inside the middle hole 281. When the second connection shaft 225 of the water receiving tub 220 is separated from the water receiving tub supporting member 280a, the opening part 282 of the water receiving tub supporting member 280a is also elastically deformed and expanded, and the second connection shaft 225 of the water receiving tub 220 can be separated from the water receiving tub supporting member 280 a.
In this way, a user can easily attach and detach water receiving tub 220 to and from the body by coupling and detaching water receiving tub 220 to and from water receiving tub supporting member 280a without using a fastening member.
Next, the operation and effect of the ice making device 200 according to the first embodiment of the present invention will be described.
Referring to fig. 1 to 7A and 7B, the water purifier 10 having the ice making device 200 may provide purified water, and provide cold or hot water, and also may prepare ice 600 to provide. Here, in order to prevent the water receiving tank 220 or the coupling 250 from being damaged if the rotation unit 240 rotates when the water receiving tank 220 or the coupling 250 of the ice-making device 200 is frozen, the ice-making device 200 of the first embodiment of the present invention has the clutch 260 combined with the coupling 250.
The coupling 250 formed with the first gear transmission 255 is combined with the water receiving tank 220, the clutch 260 formed with the second gear transmission 261 is combined with the rotating unit 240, and the first gear transmission 255 and the second gear transmission 261 are engaged with each other to rotate. Further, an elastic unit 270 such as a spring is provided between the clutch 260 and the rotary unit 240.
In a general case where the water receiving tub 220 is not frozen, the rotational force of the rotating unit 240 is transmitted to the water receiving tub 220 through the second gear transmission 261 of the clutch 260 and the first gear transmission 255 of the coupler 250, thereby rotating the water receiving tub 220, but when the water receiving tub 220 or the coupler 250 is frozen, the inclined portion 269 of the gear teeth 266 of the second gear transmission 261 moves along the inclined portion 259 of the gear teeth 256 of the first gear transmission 255 while the clutch 260 is pushed away from the coupler 250, and the elastic unit 270 is elastically deformed to be contracted, thereby allowing the clutch 260 to idle with respect to the coupler 250. Accordingly, the rotational force of the rotation unit 240 is not transmitted to the coupling 250 and the water receiving tub 220, and thus the water receiving tub 220 and the coupling 250 can be prevented from being damaged when the water receiving tub 220 or the coupling 250 is frozen.
In addition, second connection shaft 225 of water receiving tub 220 may be detachably attached to elastically deformable water receiving tub supporting member 280a, so that water receiving tub 220 may be easily and easily attached to and detached from the main body.
Fig. 8 is a separated perspective view of a water receiving tank and a coupling in a water purifier having an ice making device according to a second embodiment of the present invention.
Next, the operation and effect of the ice making device 200 according to the second embodiment of the present invention will be described with reference to the drawings, and the same portions as those of the ice making device 200 according to the first embodiment of the present invention will be replaced with the above description.
The second embodiment of the present invention is different from the first embodiment in that a coupling protrusion 252 is formed at a coupling portion 251 of a coupling 250, and a coupling groove 223 is formed at a first coupling shaft 221 on the water receiving groove 220 side.
It is adjusted that the coupling protrusion 252 of the coupling portion 251 of the coupling 250 is coupled with the coupling groove 223 of the first connection shaft 221 at the water receiving tank 220 side when the coupling portion 251 of the coupling 250 is inserted into the receiving groove 222 of the first connection shaft 221 at the water receiving tank 220 side. In fig. 8, although the pair of coupling protrusions 252 and the pair of coupling grooves 223 are illustrated, the number of the coupling protrusions 252 and the coupling grooves 223 may be different.
This has the effect of allowing the coupler 250 and the water receiving tub 220 to be coupled in the correct position and in the correct direction.
Fig. 9 is a sectional perspective view of a water receiving tray supporting member with an elastic spring in a water purifier having an ice making device according to a third embodiment of the present invention.
Next, the operation and effect of the ice making device 200 according to the third embodiment of the present invention will be described with reference to the drawings, and the same portions as those of the ice making device 200 according to the first and second embodiments of the present invention will be replaced with the above description.
The third embodiment of the present invention is different from the first and second embodiments in that water receiving tub supporting member 280b of the third embodiment of the present invention has elastic spring 285.
Water receiving tub supporting member 280b of the third embodiment may include a supporter 283, an opening 284, and an elastic spring 285. The supporter 283 may be integrally or detachably coupled to the main body and support the water receiving tank 220. The support 283 may have various shapes as long as it can support the water receiving tub 220, and may be made of various materials as long as it has rigidity for supporting the water receiving tub 220. The opening 284 is formed in the supporter 283, and the second connection shaft 225 of the water receiving tank 220 may be directly inserted into the opening 284, or as shown in fig. 9, a fixed shaft 286 coupled to the second connection shaft 225 of the water receiving tank 220 may be inserted into the opening 284. In addition, an elastic spring 285 may be inserted into the opening portion 284 and apply an elastic restoring force to the fixing shaft 286.
When the user mounts the water receiving tub 220, the fixed shaft 286 coupled to the second connecting shaft 225 at the other side of the water receiving tub 220 is inserted into the opening 284 and pulled, and then the first connecting shaft 221 at the one side of the water receiving tub 220 is connected to the rotating unit 240. Then, water receiving tub 220 is released, and water receiving tub 220 is moved by the elastic restoring force of elastic spring 285, and then is fixedly supported at both sides. When the user detaches the water receiving tub 220, the user pulls the water receiving tub 220 to contract the elastic spring, so that the first connection shaft 221 of one side of the water receiving tub 220 is separated from the rotation unit 240, and then the second connection shaft 225 of the other side of the water receiving tub 220 is withdrawn from the opening 284.
Thus, the user can easily and simply attach and detach the water receiving tank 220 to and from the body without using a fastening member.
Although the present invention has been described above with reference to the embodiments and the drawings, the present invention is not limited thereto, and it is apparent to those skilled in the art that various modifications and variations can be made in the technical spirit of the present invention and the scope equivalent to the scope of the patent protection described below.
