## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to and the benefit of Korean Patent Application No. 10-2021-0008892, filed in Korea on Jan. 21, 2021, the disclosure of which is incorporated herein by reference in its entirety.
BACKGROUND
1. Field
Disclosed herein is a liquid dispenser, such as a water purifier, and specifically, a water purifier that ensures ease of a connection and disconnection of a water discharger.
2. Background
Water purifiers are a type of liquid dispensing devices that filter water and remove impurities included in the water, and used by households and businesses and the like. A water purifier used by most households connects to a water tap and removes suspended solids or harmful substances and the like contained in tap water with a filter, and based on a user's manipulation, purifies and discharges a desired amount of water. The water purifier discharges cool water and hot water as well as purified water, and is provided with a control valve respectively for discharging cool water, hot water and purified water.
A water discharger of the water purifier can separate from a main body of the water purifier or be integrated with the main body of the water purifier. However, costs and time spent connecting a tube of a connection pipe of the water discharger to a tube of the main body and disconnecting the tube of the connection pipe of the water discharger from the tube of the main body increase.
As a related art, a water purifier and a control method thereof are disclosed in Korean Patent Publication No. 10-2020-0013021 (published on Feb. 5, 2020).

DETAILED DESCRIPTION
In the disclosure, detailed descriptions of known technologies in relation to the disclosure are omitted if they are deemed to make the gist of the disclosure unnecessarily vague. Below, preferred embodiments according to the disclosure are specifically described with reference to the accompanying drawings. In the drawings, identical reference numerals can denote identical or similar components.
FIG. 1 is a perspective view showing a water purifier (or liquid dispenser) 1 in one embodiment, and FIG. 2 is an exploded perspective view showing the water purifier 1 in one embodiment. As illustrated in FIGS. 1 and 2, the water purifier 1 in one embodiment may include at least one of a base tray (or base) 10, a filter 20, a direct water supply module 30, a cool water module (or cooler) 40, a hot water module (or heater) 50, a first controller 60, a second controller 70, a third controller 80, a water discharger (or liquid discharger) 100, and a water discharger connector (or liquid discharger connector) 200. The water purifier 1 in one embodiment provides a path connecting structure in which a water discharge pipe (or liquid discharge pipe) 230 automatically connects to a connector part (or coupling) 150 when the water discharger 100 connects to the water discharger connector 200 (see FIG. 3).
The base tray 10 forms a lower portion of the water purifier 1, and electronic components may be disposed at an upper side of the base tray 10. The filter 20 configured to purify water, the cool water module 40 configured to cool purified water, and the hot water module 50 configured to heat purified water are disposed at the upper side of the base tray 10.
The direct water supply module is disposed between the filter 20 and the cool water module 40, and controls a direction of movement of water. The hot water module 50 configured to heat water is disposed near the direct water supply module. The direct water supply module 30 connects to the cool water module 40, the hot water module 50, the water discharger connector 200 and the like through an inner tube 90.
Additionally, the first controller 60, the second controller 70 and the third controller 80 are disposed at the upper side of the base tray 10 to control valves and the like installed inside the cool water module 40, the hot water module 50 and the direct water supply module 30, thereby controlling operation of the water purifier 1. The number of the controllers may increase or decrease. For example, the first controller 60, the second controller 70, and the third controller 80 may be combined into a single component or printed circuit board.
The water discharger connector 200 provided with a water discharge valve (or liquid discharge valve) 220 is disposed at an upper side of the filter 20. The water discharger 100 is rotatably supported by an upper side of the water discharger connector 200. Through the water discharger 100, various liquids such as cool water, purified water, hot water and the like are discharged. The water purifier 1 without an outer case is illustrated in FIG. 1. The outer case is a component that is wide known. Accordingly, detailed description in relation to this is omitted.
In the water purifier 1, configured as described above, according to the disclosure, paths of the water discharger 100 and the water discharger connector 200 automatically connect only by mounting the water discharger 100 onto the water discharger connector 200, thereby prevent leakage of the connected portion, ensuring ease of assembly, maintenance and repairs.
Further, in the water purifier 1 in which the water discharger 100 is rotatable, water discharge paths automatically connect when the rotating water discharger 100 is coupled to the water discharger connector 200. Since the water discharge valve 220 is directly coupled to the water discharge pipe 230 without a connecting component, the water purifier 1 can have a compact size, and the number of components can decrease, resulting in a reduction in the costs incurred for raw materials.
FIG. 3 is a cross-sectional view showing a water discharger 100 separated from a water discharger connector 200 in one embodiment, FIG. 4 is a perspective view showing the water discharger 100 coupled to the water discharger connector 200 in one embodiment, and FIG. 5 is a cross-sectional view showing the water discharger 100 coupled to the water discharger connector 200 in one embodiment.
As illustrated in FIGS. 3 to 5, the water discharger 100 in one embodiment may include a water discharger body part (or liquid discharger body) 110, a rotation guide rail part 120, a fixed bracket part 130, a water discharger tube part (or liquid discharger tube) 140 and a connector part (or coupling) 150.
As the water discharger 100 is mounted onto the water discharger connector 200, the water discharge pipe (or liquid discharge pipe) 230 connects to the connector part 150. As the water discharger 100 rotatably disposed at the water discharger connector 200 moves to upper and lower sides of the water discharger connector 200, to be mounted onto the water discharger connector 200, the water discharge pipe 230 is inserted into a lower side of the connector part 150 such that the water discharge pipe 230 automatically connects to the connector part 150.
The water discharger 100 may be implemented in various different forms within the technical scope in which the water discharger 100 is coupled to the upper side of the water discharger connector 200 and provided with the connector part 150 connected to the water discharge pipe 230 based on fitted-coupling. Additionally, the water discharger 100 may be rotatably disposed at the water discharger connector 200.
The water discharger body part 110 may be implemented in various different forms within the technical scope in which the water discharger body part 110 is disposed at the upper side of the water discharger connector 200. The water discharger body part 110 in one embodiment may include a first body 112 extended vertically and having a hollow part (or cavity) 114 therein, and a second body 116 extended from the first body 112 and disposed at the upper side of the water discharger connector 200.
While the second body 116 extends along a circumferential shape, the rotation guide rail part (or rotation guide rail) 120 connects to a lower side of the second body 116. The water discharger tube part 140 is installed inside the first body 112 and the second body 116.
The rotation guide rail part 120 may be implemented in various different forms within the technical scope in which the rotation guide rail part 120 is disposed a lower side of the water discharger 100 facing the water discharger connector 200 and mounted onto a fixed guide rail part (or fixed guide rail) 240. The rotation guide rail part 120 connected to a lower side of the water discharger body part 110 may be mounted onto the fixed guide rail part 240 disposed at the water discharger connector 200 and rotate along a circumferential direction. To this end, the rotation guide rail part 120 may extend at the lower side of the water discharger body part 110 along the circumferential direction and be mounted onto a guide groove 246 with which the fixed guide rail part 240 is provided. The rotation guide rail part 120 extends along a ring shape and protrudes downward to sit inside the fixed guide rail part 240.
The fixed bracket part (or fixed bracket) 130 may be implemented in various different forms within the technical scope in which the fixed bracket part 130 extends to an inside of the rotation guide rail part 120 and limits movement of the connector part 150. The connector part 150 connects to the water discharger tube part 140, and its movement is limited by the fixed bracket part 130. The fixed bracket part 130 in one embodiment includes an extension bracket 132, a first bracket 134, and a second bracket 138 (see FIG. 6).
The extension bracket 132 extends from the rotation guide rail part 120 to the connector part 150. The connector part 150 is disposed at a rotation center of the water discharger 100, and the extension bracket 132 extended from the water discharger body part 110 or the rotation guide rail part 120 forms a bracket extended toward the connector part 150.
The first bracket 134 connects to the extension bracket 132 and is disposed along a circumference of the connector part 150. Additionally, both ends of the first bracket 134 are spaced to form a mounting inlet 136 (see FIG. 6). The first bracket 134 extends along the circumference of the connector part 150 and connects to the extension bracket 132. Since both of the ends of the first bracket 134 are spaced to form the mounting inlet 136, the connector part 150 may move in and out of the first bracket 134 through the mounting inlet 136.
The second bracket 138 may be implemented in various different forms within the technical scope in which the second bracket 138 extends from the first bracket 134, and is inserted into a mounting groove 154 provided outside the connector part 150 and limits movement of the connector part 150. The second bracket 138 is disposed between the first bracket 134 and the connector part 150, extends vertically, and contacts a lateral surface of the connector part 150. A plurality of second brackets 138 is provided along the circumference the connector part 150. Since the second bracket 138 is inserted onto the mounting groove 154 provided outside the connector part 150, the second bracket 138 may limit movement of the connector part 150.
The connector part 150, connected to the water discharger tube part 140 and connected to or disconnected from the water discharge pipe 230 by moving vertically, is installed in a state of being fixed to the rotation center of the water discharger 100. The first bracket 134 and the second bracket 138 may be injection-molded, have elasticity and bend to some degree. Accordingly, the connector part 150 is disposed inside the second bracket 138 through the mounting inlet 136, and its movement is limited by a press of the second bracket 138.
The water discharger connector 200 is provided with the water discharge valve (or liquid discharge valve) 220, and the water discharge pipe 230, connected to the water discharge valve 220 and extended upward, is inserted into the lower side of the connector part 150. Since the water discharge pipe 230 and the connector part 150 are disposed at the rotation center of the water discharger 100, the rotation center of the water discharger 100 is the same as positions of the water discharge pipe 230 or the connector part 150.
One side of the water discharger tube part 140 may connect to the connector part 150, and the other side of the water discharger tube part 140 may extend out of the water discharger body part 110 through the inside of the water discharger body part 110 or be disposed inside the water discharger body part 110. The water discharger tube part 140 in one embodiment may include a first tube 142 disposed inside the first body 112, a second tube 144 disposed inside the second body 116, and a connection tube 146 connecting the second tube 144 and the connector part 150.
The first tube 142 and the second tube 144 may be integrated and guide discharge of water. Additionally, the connection tube 146 is a tube bent in a “¬” shape, and connects an end of the second tube 144 and the connector part 150 and guides movement of water.
FIG. 6 is a perspective view showing a water discharge pipe 230 connected to a connector part 150 in one embodiment, FIG. 7 is a partially cut perspective view showing the water discharge pipe 230 connected to the connector part 150 in one embodiment, and FIG. 8 is a perspective view showing the water discharger 100 and the water discharger connector 200 in one embodiment. As illustrated in FIGS. 6 to 8, the connector part 150 may be implemented in various different forms within the technical scope in which the connector part 150 connects the water discharger tube part 140 and the water discharge pipe 230. The connector part 150 is disposed at an upper side of the water discharge pipe 230, and connected to the water discharge pipe 230 based on fitted-coupling.
The connector part 150 connected to the water discharge pipe 230 has no additional wedge structure for limiting a vertical movement of the water discharge pipe 230, therein. Accordingly, the water discharge pipe 230 and the connector part 150 may be coupled or separated only by assembling and disassembling the water discharger 100. The connector part 150 in one embodiment may include a connector body 152, a first connection groove (or first connection opening) 155, a second connection groove (or second connection opening) 156, and a sealing member (or seal) 157.
The connector body 152 is disposed at the rotation center of the water discharger 100 and extends vertically. The connector body 152 has an approximate cylinder shape, and a path through which purified water moves is formed vertically inside the connector body 152.
The first connection groove 155 forms a groove for inserting the water discharge pipe 230, at a lower side of the connector body 152. Accordingly, the water discharge pipe 230 is inserted into the lower side of the connector body 152 through the first connection groove 155.
The second connection groove 156 forms a groove into which the water discharger tube part 140 forming a water discharge path is inserted, at an upper side of the connector body 152. Since the first connection groove 155 and the second connection groove 156 communicate vertically, a liquid such as purified water, moving upward through the water discharge pipe 230, is delivered to the water discharger tube part 140 through the connector part 150.
The sealing member 157 is disposed near the water discharger tube part 140 inserted into the connector part 150 and near the water discharge pipe 230. The installation of the sealing member 157 leads to prevention of leakage of water out of the water discharger tube part 140 and the water discharge pipe 230.
The water discharger connector 200 may be implemented in various different forms within the technical scope in which the water discharger connector 200 is provided with the water discharge valve 220 configured to control discharge of purified water, and the water discharge pipe 230 connected to the water discharge valve 220. The water discharger connector 200 in one embodiment may include a water discharger connector body (or liquid discharger connector body) 210, a water discharge valve (or liquid discharge valve) 220, a water discharge pipe (or liquid discharge part) 230, a fixed guide rail part (or fixed guide rail) 240.
The water discharger connector body 210 supports the water discharge valve 220, and is disposed at the upper side of the filter 20 in a state in which movement of the water discharger connector body 210 is limited. The water discharger connector body 210 is disposed at the lower side of the second body 116 and limits movement of the water discharge valve 220.
The water discharge valve 220 is a valve that controls discharge of purified water. A connector such as a hook or a screw may be used to fix the water discharge valve 220 to the water discharger connector body 210, and a gap may be formed between the water discharge valve 220 and the water discharger connector body 210 to prevent leakage caused by errors in the coupling portion of the rotating water discharger 100.
The water discharge pipe 230 is disposed at the rotation center of the water discharger 100 and extends perpendicularly. A rigid pipe is used as the water discharge pipe 230 rather than a soft pipe. As the water discharger 100 is mounted onto the upper side of the water discharger connector 200 while moving from the upper side of the water discharger connector 200 to the lower side thereof, the water discharge pipe 230 and the connector part 150 connect.
The fixed guide rail part 240 connects to an upper side of the water discharger connector body 210 and forms the guide groove 246 along the circumferential direction. Accordingly, the fixed guide rail part 240 may be implemented in various different forms within the technical scope in which the fixed guide rail part supports the rotation guide rail part 120 of the water discharger 100 rotatably. The fixed guide rail part 240 in one embodiment includes a base rail 242 and a side member 244 (or side wall).
The base rail 242 is disposed at a lower side to face the water discharger 100, and extends along the circumferential direction, to form a lower surface of the guide groove 246. The base rail 242 forms a flat surface along the circumferential direction, and the rotation guide rail part 120 is mounted onto the base rail 242 while contacting the base rail 242.
Since the side member 244 forms a wall that protrudes upward from both sides of the base rail 242 and prevents the rotation guide rail part 120 mounted onto the guide groove 246 from escaping. A longitudinal cross section of the fixed guide rail part 240 has a “⊏” or U-shape that is open upward, and the guide groove 246 is formed by the base rail 242 and the side member 244.
As the water discharger 100 is mounted onto the upper side of the water discharger connector 200 while moving from the upper side of the water discharger connector 200 to the lower side thereof, the water discharge pipe 230 and the connector part 150 connect. The rotation guide rail part 120 of the water discharger 100 is mounted onto the fixed guide rail part 240 of the water discharger connector 200. As the water discharger 100 moves downward, the water discharge pipe 230 is inserted into the first connection groove 155 of the connector part 150.
Only by connection the water discharger 100 to the water discharger connector 200, the water discharge pipe 230 and the water discharger tube part 140 are connected by the connector part 150, thereby reducing the risk of leakage in the coupling portion and ensuring ease of assembly and management. Additionally, the water discharge valve 220 directly connects to the water discharge pipe without a connecting component, thereby making a product compact and reducing costs incurred for raw materials.
Further, when the water discharger 100 moves to the upper side of the water discharger connector 200 and separates from the water discharger connector 200, the water discharge pipe 230 automatically separates from the connector part 150. Accordingly, additional work for separating the paths is not required. Furthermore, since the connector part 150 and the water discharge pipe 230 have a rigid body, the paths automatically separate only by separating the water discharger 100 from the water discharger connector 200.
An aspect of the present disclosure provides a water purifier that ensures ease of a connection and disconnection of a water discharger. Also, as aspect of the present disclosure provides a water purifier that ensures simplicity in the installation structure of the water discharger, reducing manufacturing costs incurred for the product and making the product compact.
