Description

Water discharging apparatus

The present invention relates to a water discharge device, and more specifically, to a water discharge device having an attractive appearance after installation.

A water purifier is a device that receives raw water, filters it, creates purified water, and supplies the created purified water to the outside. Recently, as living standards have improved, water purifiers are being widely used not only in businesses but also in homes.

A water purifier includes a component for filtering raw water to produce purified water, such as a filter. In addition, depending on its type, the water purifier may heat or cool the produced purified water to provide hot or cold water. To this end, the water purifier may include a component for heating or cooling purified water, such as a heater or cooler.

In the above case, the water purifier can provide various types of water to the user, which can improve the user's satisfaction and convenience. On the other hand, as the above components are provided, the volume of the water purifier increases, which can increase the space it occupies in the home.

Accordingly, recently, a type of water purifier that accommodates the above-mentioned components of the water purifier in the interior space of the sink and exposes only the components for discharging water on the outside of the sink has been gaining attention. The above-mentioned type of water purifier, generally referred to as a built-in type water purifier, minimizes the components that expose the water purifier to the outside, thereby securing a wide space for the installation of the water purifier.

At this time, the configuration for water discharge is connected through the top of the sink, etc., so that some of it is exposed to the sink ball and other parts are located in the internal space of the sink.

In the above case, the configuration for the outlet exposed to the sink bowl can be fluidly connected to another configuration located in the interior space of the sink through a separate member. For stable connection, it is preferable that the configuration for the outlet and the other configuration are connected through a fastening member.

However, if the component for combining the configuration for the water discharge and the other components is exposed to the outside, it is difficult to secure an attractive appearance. In addition, if the component protrudes, there is also a risk of safety accidents occurring while the user is using the water purifier.

U.S. Patent Publication No. 2010-0101017 discloses an easy-to-maintain detection automatic faucet. Specifically, the automatic faucet is disclosed to include a mounting unit that is coupled to a mounting hole in a deck and is secured to the deck by bolts extending in an up-down direction, and a housing that surrounds the outer periphery of the mounting unit and has a locking bolt coupled through the side.

However, the automatic faucet disclosed in the above prior document only provides a method for facilitating the process of joining with the deck. That is, the above prior document does not provide a method for preventing the locking bolt that joins the housing and the mounting unit from being exposed to the outside.

Korean Patent Publication No. 10-2020-0102799 discloses a water dispensing device. Specifically, the water dispensing device is disclosed in which a groove is formed in a penetrating member that is penetratingly connected to a sink, and a connecting piece formed of an elastic material is inserted into the groove to connect an inner member that forms a flow path on the outside of the sink and the penetrating member.

However, the inner member and the penetrating member disclosed in the above-mentioned prior document are assumed to be elastically joined to each other. The above-mentioned prior document does not provide a method for joining the inner member and the penetrating member using a member made of an inelastic material, such as a screw member. Therefore, the joining structure of the inner member and the penetrating member disclosed in the above-mentioned prior document has the limitation that it can be applied only when elastically joined.

Furthermore, the above prior documents do not provide a method for attaching a water purifier outside the sink rather than in the narrow interior space of the sink.

Referring to FIG. 1, a water extraction device (10) according to one embodiment of the present invention is illustrated.

The water discharge device (10) according to an embodiment of the present invention may be penetrated and connected to a plate (P) as an installation target, so that a portion of the device may be positioned on the upper side of the plate (P) and the remaining portion may be positioned on the lower side of the plate (P). That is, the water discharge device (10) according to an embodiment of the present invention may be provided in a built-in form.

When the discharge device (10) is combined with the plate (P), work for fastening with other components can be performed on the upper side of the plate (P). That is, the discharge device (10) according to the embodiment of the present invention does not have to be installed inside a relatively narrow sink. Accordingly, the installation work of the discharge device (10) can be easily performed.

Meanwhile, the extraction device (10) according to each embodiment of the present invention may not have the components for combining each component exposed to the outside.

Specifically, the discharge device (10) may have some components rotatably coupled to the plate (P). At this time, the components for coupling may not be exposed on the front side of the discharge device (10) that the user primarily looks at.

Accordingly, only the beautifully formed exterior (i.e., the outer housing (100)) can be exposed to the user who is discharging water from the water discharging device (10). Accordingly, the exterior of the entire water discharging device (10) can be beautifully formed, thereby improving user satisfaction.

In the embodiment shown in FIGS. 1 and 2, the discharge device (10) includes an outer housing (100), an inner housing (200), an installation member (300), a pin member (400), and a fastening member (500).

The outer housing (100) constitutes the outer shape of the discharge device (10). The outer housing (100) is a portion of the discharge device (10) located on the upper side of the plate (P). The outer housing (100) is directly exposed to the user.

The outer housing (100) may be supported by a plate (P). In one embodiment, the outer housing (100) may be mounted on the plate (P).

The outer housing (100) can be coupled with the inner housing (200). The outer housing (100) accommodates the inner housing (200) and can be coupled with the inner housing (200). The inner housing (200) is not exposed to the outside by the outer housing (100).

At this time, a part of the outer housing (100), that is, the outlet housing (110) to be described later, may be rotatably coupled with respect to the inner housing (200). In addition, another part of the outer housing (100), that is, the extension housing (120) to be described later, may be coupled with respect to the inner housing (200) at a variable angle. In addition, when the pin member (400) is coupled with the extension housing (120) and the inner housing (200), the relative angle of the extension housing (120) and the inner housing (200) may be fixed.

In the illustrated embodiment, the outer housing (100) includes an outlet housing (110) and an extension housing (120).

The water outlet housing (110) constitutes a part of the outer housing (100). The water outlet housing (110) is a part from which water is discharged by the user's operation. Accordingly, the water outlet housing (110) may be defined as a faucet.

The outlet housing (110) is coupled with the inner housing (200). At this time, the space formed inside the outlet housing (110) and the space formed inside the inner housing (200) can be communicated with each other. In addition, the space formed inside the outlet housing (110) is communicated with the outside. Accordingly, water can be provided to the user through the inner space of the inner housing (200) and the inner space of the outlet housing (110) in sequence.

The outlet housing (110) can be rotatably coupled to the inner housing (200). In the above embodiment, the outlet housing (110) can be rotated relative to the inner housing (200) while the inner housing (200) is fixed at a specific angle. As will be described later, the extension housing (120) is restricted from rotating relative to the inner housing (200) by the pin member (400), so it can be said that the outlet housing (110) is provided to be rotatably connected to the extension housing (120).

The outlet housing (110) may be extended at a predetermined angle with respect to the extension housing (120) or the inner housing (200). In the illustrated embodiment, the outlet housing (110) is extended in a horizontal direction and formed perpendicular to the extension housing (120) or the inner housing (200) that extends in a vertical direction.

The extension housing (120) constitutes another part of the outer housing (100). The extension housing (120) is a part where the outer housing (100) is joined to the inner housing (200).

A hollow is formed inside the extension housing (120). The hollow of the extension housing (120) accommodates the inner housing (200) and the installation member (300) coupled thereto. By the extension housing (120), the inner housing (200), the installation member (300) and the fastening member (500) coupling them are not exposed to the outside.

The extension housing (120) can be fixedly connected to the inner housing (200) by the pin member (400). That is, as will be described later, when the pin member (400) is not connected to the pin member connecting hole (121) and the pin member connecting portion (240), the extension housing (120) can be rotated relative to the inner housing (200). When the pin member (400) is connected to the extension housing (120) and the inner housing (200), respectively, the extension housing (120) can be fixed relative to the inner housing (200).

In addition, the extension housing (120) can be rotatably mounted on the plate (P). For this purpose, the extension housing (120) can have a shape corresponding to the outer circumference of the inner housing (200). In the illustrated embodiment, the extension housing (120) has an annular cross-section with the hollow formed therein and is a cylindrical shape having a height in the vertical direction.

In the embodiment illustrated in FIG. 3, the extension housing (120) includes a pin-less coupling hole (121).

The pin member joining hole (121) is a space where the pin member (400) is joined. The pin member joining hole (121) is formed radially through the outer periphery of the extension housing (120). The pin member joining hole (121) radially connects the hollow formed inside the extension housing (120) with the outside.

The pin-less coupling hole (121) may be positioned offset to one side of the length direction of the extension housing (120). In the illustrated embodiment, the pin-less coupling hole (121) is positioned adjacent to one side, i.e., the lower end, of each end of the extension housing (120) that is seated on the plate (P).

At this time, the pin member joining hole (121) is positioned apart from the lower end of the extension housing (120). Therefore, the outer periphery of the extension housing (120) is at least partially positioned between the pin member joining hole (121) and the lower end of the extension housing (120).

The pin member joining hole (121) may have a shape corresponding to the shape of the pin member (400). In the illustrated embodiment, the pin member joining hole (121) is formed to have a cross section having a pair of straight lines facing each other and a pair of curved surfaces that are continuous with each of the pair of straight lines and facing each other.

The position of the pin member joining hole (121) may be changed depending on the position of the fastening member receiving hole (232) or the pin member through hole (242) provided in the inner housing (200). In other words, the vertical height of the pin member joining hole (121) may be determined corresponding to the vertical height of the fastening member receiving hole (232) or the pin member through hole (242).

As described above, the extension housing (120) rotatably accommodates the inner housing (200). When the extension housing (120) is rotated, either one of the fastening member receiving hole (232) and the pin member through hole (242) provided in the inner housing (200) can be exposed to the outside through the pin member joining hole (121).

Accordingly, the fastening member (500) can be coupled to the fastening member receiving hole (232) by penetrating the pin member joining hole (121). Similarly, the pin member (400) can be coupled to the pin member through hole (242) by penetrating the pin member joining hole (121). A detailed description thereof will be given later.

The inner housing (200) constitutes a part of the configuration of the discharge device (10) that is not exposed to the outside. The inner housing (200) is located on the upper side of the plate (P), but is accommodated in the outer housing (100) and is not exposed to the outside.

A plurality of fastening member support members (231) may be provided. The plurality of fastening member support members (231) are spaced apart in a direction different from the direction in which a pair of fastening member joints (230) are spaced apart, so that they can each support a single fastening member (500). In the illustrated embodiment, the fastening member support members (231) are provided in a pair and spaced apart in the front-back direction. It will be understood that the direction is the same as the extension direction of the fastening member receiving hole (232).

The fastening member receiving hole (232) receives the fastening member (500). The fastening member receiving hole (232) extends in the joining direction of the fastening member (500), i.e., in the forward-backward direction in the illustrated embodiment.

The fastening member receiving hole (232) is at least partially connected to the internal housing space (220). In the illustrated embodiment, the fastening member receiving hole (232) is connected to the internal housing space (220) along the front-rear direction.

The fastening member receiving hole (232) may extend across the inner housing outer surface (211) and the pair of fastening member support members (231). In other words, the fastening member receiving hole (232) is formed through and extends through the inner housing outer surface (211) and the interior of the pair of fastening member support members (231).

In an embodiment in which the fastening member (500) is provided as a screw member, screw threads may be formed on the inner surface of the fastening member support member (231) surrounding the fastening member receiving hole (232).

The fastening member receiving hole (232) can be selectively connected to the outside by rotation of the outer housing (100).

Specifically, when the extension housing (120) is rotated so that the pin member coupling hole (121) and the fastening member coupling portion (230) are arranged to overlap in a radial or horizontal direction, the fastening member receiving hole (232) can be exposed to the outside through the pin member coupling hole (121). In this state, the fastening member (500) can be coupled with the fastening member receiving hole (232) through the pin member coupling hole (121).

In addition, when the extension housing (120) is rotated so that the pin member coupling hole (121) and the fastening member coupling portion (230) are positioned so that they do not overlap in the radial or horizontal direction, the fastening member receiving hole (232) and the fastening member (500) coupled thereto are not exposed to the outside.

The pin member joint (240) is a portion where the inner housing (200) is joined to the pin member (400). The pin member joint (240) may include a configuration for joining the pin member (400) and a configuration for supporting the configuration.

The pin-less coupling portion (240) is formed in the inner housing body (210). In the illustrated embodiment, the pin-less coupling portion (240) is located on one side of the longitudinal direction of the inner housing body (210), in the illustrated embodiment, on the lower side.

The pin-less coupling portion (240) is positioned apart from the fastening member coupling portion (230). Specifically, the pin-less coupling portion (240) is positioned apart from the fastening member coupling portion (230) along the outer circumferential direction of the inner housing body (210). In the illustrated embodiment, the pin-less coupling portion (240) is positioned between a pair of fastening member coupling portions (230) that are spaced apart in the left-right direction.

At this time, the pin member joining portion (240) is located on the rear side of the inner housing body (210). Therefore, it will be understood that when a user uses the discharge device (10) in a normal direction, the pin member joining portion (240) and the pin member (400) joined thereto are not exposed to the user.

The pin member joining portion (240) may be provided in a single number. This is because the pin member (400) described later is provided in a single number. The pin member joining portion (240) may be changed according to the number of pin members (400).

When the pin member (400) is coupled to the pin member (240), the outer housing (100) does not rotate relative to the inner housing (200).

In the illustrated embodiment, the pin member joint (240) includes a pin member support member (241) and a pin member through hole (242).

The pin member support member (241) supports the coupled pin member (400). The pin member support member (241) may be defined as a portion of the inner housing outer surface (211) that surrounds the pin member through-hole (242). In the illustrated embodiment, the pin member support member (241) surrounds the pin member through-hole (242) in the outer circumferential direction of the inner housing body (210).

A plurality of pin member support members (241) may be provided. A plurality of pin member support members (241) may surround the pin member through hole (242) at different positions along the outer circumferential direction of the inner housing body (210). In the illustrated embodiment, a pair of pin member support members (241) are provided, respectively surrounding the pin member through hole (242) on the front side and the rear side.

The pin member through hole (242) accommodates the pin member (400). The pin member through hole (242) is formed through the inner housing outer surface (211) in the coupling direction of the pin member (400), i.e., in the front-back direction in the illustrated embodiment.

The pin member through-hole (242) communicates with the inner housing space (220). The pin member (400) can be at least partially positioned in the inner housing space (220) through the pin member through-hole (242). In the illustrated embodiment, the pin member through-hole (242) communicates with the inner housing space (220) along the engaging direction of the pin member (400), i.e., the front-rear direction.

The pin absence through hole (242) can be selectively connected to the outside by rotation of the outer housing (100).

Specifically, when the extension housing (120) is rotated so that the pin member coupling hole (121) and the pin member through hole (242) overlap in a radial or horizontal direction, the pin member through hole (242) can be exposed to the outside through the pin member coupling hole (121). In this state, the pin member (400) can be penetratedly coupled to the pin member through hole (242) through the pin member coupling hole (121).

In addition, when the extension housing (120) is rotated so that the pin member joining hole (121) and the pin member through hole (242) are positioned so that they do not overlap in the radial or horizontal direction, the pin member through hole (242) is not exposed to the outside.

The installation member (300) is a part where the discharge device (10) is connected to the plate (P). The installation member (300) is fixedly connected to the plate (P) and supports other components of the discharge device (10). By means of the installation member (300), other components of the discharge device (10) can also be connected to the plate (P).

In one embodiment, the installation member (300) may be provided together with or separately from the discharge device (10). The installation member (300) may be connected by penetrating the plate (P) on which the discharge device (10) is to be installed, such that a portion of the installation member may be positioned on the upper side of the plate (P) and the remaining portion may be positioned on the lower side of the plate (P).

The outer housing (100) and the inner housing (200) can be combined with the plate (P) by an installation member (300) combined with the plate (P).

After the installation member (300) penetrates the insertion hole (H) formed in the plate (P), a process of tightening it so that it is in close contact with the plate (P) can be performed. At this time, the process of attaching the installation member (300) to the plate (P) can be performed on one side of the height direction of the plate (P), that is, on the upper side.

Therefore, when the water outlet device (10) is provided in a built-in form and installed in a sink, etc., the installation process of the installation member (300) and the water outlet device (10) can be performed on the outside of the sink.

As a result, the work for installing the installation member (300) and the water outlet device (10) does not have to be performed in the narrow interior space of the sink. Accordingly, the convenience of the work for installing the installation member (300) and the water outlet device (10) can be improved.

In addition, the direction in which the installation member (300) is coupled with the plate (P), the direction of the force applied to bring the plate (P) and the installation member (300) into close contact, and the direction in which the water discharge device (10) is coupled with the installation member (300) can all be formed in the height direction of the installation member (300), that is, in the up-down direction in the illustrated embodiment.

Accordingly, the installation process of the installation member (300) and the discharge device (10) can be carried out more easily.

In the following description, it is assumed that the installation member (300) is provided in a built-in form and is combined with the top plate of a sink or sink bowl. Alternatively, it will be understood that the installation member (300) may be applied to combine an arbitrary form of device that penetrates an arbitrary plate member, with a portion of the device being exposed to the outside and the remainder being accommodated inside, with the plate member.

In the embodiments illustrated in FIGS. 8 and 9, the installation member (300) includes an installation housing (310), a support member (320), and a fastening member coupling member (330).

The installation housing (310) constitutes a part of the outer shape of the installation member (300). The installation housing (310) is a part where the installation member (300) is coupled to the plate (P). Specifically, a part of the installation housing (310) is mounted on one side of the plate (P), in the illustrated embodiment, the upper side. Another part of the installation housing (310) is formed through an insertion hole (H) formed through the plate (P) and is at least partially exposed to the lower side of the plate (P).

The installation housing (310) may have a shape corresponding to the shape of the plate (P) or the insertion hole (H). In the illustrated embodiment, the installation housing (310) has a three-dimensional shape with a circular cross-section and a height in the vertical direction. At this time, each part of the installation housing (310) may be formed to have a different cross-sectional area along the height direction. Accordingly, the above-mentioned part of the installation housing (310) may be positioned above the plate (P), and the above-mentioned other part of the installation housing (310) may be positioned below the plate (P).

The installation housing (310) is coupled to the support member (320). The installation housing (310) can be brought into close contact with the plate (P) by the support member (320).

The installation housing (310) can movably accommodate the support member (320). That is, in the illustrated embodiment, the installation housing (310) can movably accommodate the support member (320). At the same time, the installation housing (310) can radially accommodate the support member (320).

As will be described later, the support member (320) may be formed to have a height in the same direction as the installation housing (310), i.e., a height in the vertical direction. The support member (320) may be rotated radially about a portion of the vertical portion as an axis. Accordingly, a portion of the support member (320) may be positioned to be exposed or not exposed to the outside of the installation housing (310).

Due to the structure of the support member (320) as described above and the coupling relationship between the installation housing (310) and the support member (320), a part of the installation housing (310) can penetrate into the insertion hole (H).

The installation housing (310) is coupled with a tightening member (not indicated in the drawing). The installation housing (310) can be brought into close contact with the support member (320) and the plate (P) by the tightening member (not indicated in the drawing).

In the illustrated embodiment, the lower portion of the installation housing (310) penetrates the insertion hole (H) of the plate (P) and is positioned on the lower side of the plate (P). The upper portion of the installation housing (310) is formed to have a cross-section with a larger diameter than the insertion hole (H) and is positioned on the upper side of the plate (P).

The support member (320) is coupled with the installation housing (310). The support member (320) can be elevated to come into contact with or be separated from the plate (P). By the close contact between the support member (320) and the plate (P), the installation member (300) can be coupled with the plate (P).

The support member (320) is coupled with the plate (P). Specifically, the support member (320) is coupled with the installation housing (310) and penetrates the insertion hole (H) to be coupled with the plate (P).

The support member (320) is movably coupled to the installation housing (310). At this time, the support member (320) can be rotated in the width direction of the installation member (300), or left and right in the illustrated embodiment, with the coupled tightening member (not given a drawing symbol) as an axis. By the rotation, the support member (320) can be exposed to the outside of the installation housing (310) or accommodated in the inside of the installation housing (310). Accordingly, the support member (320) and the installation housing (310) coupled thereto can penetrate the insertion hole (H).

The support member (320) is movably connected to the installation housing (310). When the support member (320) is raised, the remaining portion of the support member (320) can be brought into close contact with the plate (P). When the support member (320) is lowered, the remaining portion of the support member (320) can be separated from the plate (P). The elevation of the support member (320) can be achieved by connection with a tightening member (not given a drawing symbol).

The support member (320) is coupled with a tightening member (not given a drawing symbol). It penetrates the support member (320). When an external force is applied to the tightening member (not given a drawing symbol), the support member (320) can be raised and lowered. In addition, when an external force is applied to the tightening member (not given a drawing symbol), the support member (320) can be moved in the width direction of the installation member (300), or in the left and right direction in the illustrated embodiment.

A plurality of support members (320) may be provided. A plurality of support members (320) may be coupled with the installation housing (310), the tightening member (not given a drawing symbol) and the plate (P) at different locations. In the illustrated embodiment, a pair of support members (320) are provided, each positioned on the front side and the rear side.

The fastening member joining member (330) is a portion where the installation member (300) is joined to the fastening member (500). The fastening member joining member (330) is positioned on the upper side of the plate (P), and is positioned adjacent to the pin member joining hole (121) and the fastening member joining portion (230) which are also positioned on the upper side of the plate (P).

The fastening member joining member (330) is continuous with the portion of the installation member (300) located on the upper side of the plate (P). In the illustrated embodiment, the fastening member joining member (330) is formed to protrude upward from the plate-shaped member that is seated on the plate (P).

The fastening member joining member (330) is positioned adjacent to the pin joining hole (121). The fastening member joining member (330) can be positioned to overlap the pin joining hole (121) in a radial or horizontal direction as the extension housing (120) rotates.

The fastening member joining member (330) is positioned adjacent to the fastening member receiving hole (232). The fastening member joining member (330) may be positioned to overlap the fastening member receiving hole (232) in a radial or horizontal direction.

The fastening member joining member (330) can extend along the joining direction of the fastening member (500). In the illustrated embodiment, the fastening member joining member (330) extends in the forward-backward direction.

A plurality of fastening member joining members (330) may be provided. The plurality of fastening member joining members (330) may be spaced apart in a direction different from the extension direction thereof, and may be respectively connected to the plurality of fastening members (500). In the illustrated embodiment, the fastening member joining members (330) are provided in pairs and spaced apart in the left-right direction.

A fastening cavity (331) is formed inside the fastening member (330).

The fastening cavity (331) is a space formed inside the fastening member joining member (330). The fastening cavity (331) extends in the extension direction of the fastening member joining member (330), in the forward and backward direction in the illustrated embodiment. Each end of the extension direction of the fastening cavity (331), in the illustrated embodiment, the front side and the rear side, are each formed open, so that the fastening member (500) can pass through.

The fastening hollow (331) may be arranged to overlap with the fastening member receiving hole (232). In other words, the fastening hollow (331) is arranged to overlap with the fastening member receiving hole (232) along the direction in which the fastening member (500) is coupled, i.e., the front-rear direction in the illustrated embodiment.

Accordingly, it will be understood that when the extension housing (120) is rotated so that the pin member joining hole (121) overlaps the fastening member receiving hole (232), the fastening hollow (331) is also arranged to overlap the pin member joining hole (121).

The fastening cavity (331) may have any shape to which the fastening member (500) can be joined. In the illustrated embodiment, the fastening cavity (331) is a cylindrical space having a circular cross-section and extending in the front-back direction. In the embodiment in which the fastening member (500) is provided as a screw member, screw threads may be formed on the inner surface of the fastening member joining member (330) surrounding the fastening cavity (331).

The pin member (400) restrains the outer housing (100) from rotating relative to the inner housing (200). The pin member (400) is coupled to each of the outer housing (100) and the inner housing (200).

The pin member (400) is coupled with the outer housing (100). Specifically, the pin member (400) is penetratedly coupled into a pin member coupling hole (121) formed on the lower side of the extension housing (120). A portion of the pin member (400) may be supported by an outer surface of the extension housing (120) surrounding the pin member coupling hole (121).

The pin member (400) is coupled with the inner housing (200). Specifically, the pin member (400) is coupled through the pin member through hole (242) and supported by the pin member support member (241).

As described above, the pin member joining portion (240) is exposed to the outside only when it is arranged to overlap the pin member joining hole (121) in the radial direction or the horizontal direction. Therefore, it will be understood that the pin member (400) can be joined to the pin member joining hole (121) and the pin member through hole (242) only in the above state.

The pin member (400) can be coupled with the outer housing (100) and the inner housing (200) in the direction in which the area exposed to the user among each side of the water discharge device (10) is the minimum. In the illustrated embodiment, the pin member (400) is positioned in the direction opposite to the direction in which the water discharge housing (110) extends, i.e., on the rear side. Therefore, unless the user intentionally rotates the outer housing (100), the pin member (400) is not exposed to the user. As a result, the appearance of the water discharge device (10) can be formed to be attractive.

The pin member (400) may be formed of a material having a predetermined elasticity. When the pin member (400) is coupled to the pin member joining hole (121) or the pin member through hole (242), the pin member (400) is deformed in shape and stores restoring force, and is supported by the outer periphery of the extension housing (120) or the pin member supporting member (241) by the stored restoring force. In the above case, the state of coupling between the pin member (400) and the outer housing (100) or the inner housing (200) can be stably maintained.

In one embodiment, the pin member (400) may be formed of a rubber or silicone material.

In the embodiments illustrated in FIGS. 10 and 11, the pin member (400) includes a pin body (410), a pin projection (420), a pin boss (430), and a pin grip portion (440).

The pin body (410) constitutes a part of the outer shape of the pin member (400). The pin body (410) is a part of the pin member (400) that penetrates the pin member through hole (242) and is positioned in the internal housing space (220).

The pin body (410) extends in the direction in which the pin member (400) is coupled with the outer housing (100) or the inner housing (200), in the forward and backward direction in the illustrated embodiment.

The pin body (410) may have a shape corresponding to the pin member through hole (242). In the illustrated embodiment, the pin body (410) is formed to have a cross section having a pair of straight lines and a pair of curved lines continuous with the pair of straight lines.

The pin body (410) is continuous with the pin projection (420). The pin projection (420) may be located at one end of the pin body (410) in the direction of extension, toward the outer housing (100) or the inner housing (200), and in the illustrated embodiment, at the outer periphery of the front end.

The pin body (410) is continuous with the pin boss (430). The pin boss (430) can be located at one end of the pin body (410) in the extension direction, opposite to the outer housing (100) or the inner housing (200), in the illustrated embodiment, at the rear end.

At this time, the outer circumference of the cross-section of the pin body (410) may be formed shorter than the outer circumference of the cross-section of the pin boss (430). Accordingly, the cross-sectional area of the pin body (410) may be formed smaller than the cross-sectional area of the pin boss (430). In the above embodiment, the cross-sectional area of the pin member through hole (242) may be formed smaller than the cross-sectional area of the pin member joining hole (121).

In addition, the cross-sectional area of the pin body (410) may be less than or equal to the cross-sectional area of the pin member through-hole (242). Accordingly, the pin body (410) may be pressed inward to be deformed and may penetrate the pin member through-hole (242). For this purpose, a pin space (411) is formed inside the pin body (410).

The pin space (411) is formed inside the pin body (410) to cushion the shape deformation in the inward direction of the pin body (410). The pin space (411) extends in the extension direction of the pin body (410), in the forward and backward direction in the illustrated embodiment. One side of the extension direction of the pin space (411), in the illustrated embodiment, the front side, is formed open.

The pin projection (420) is a portion that is combined with the pin member support member (241). As the pin projection (420) and the pin member support member (241) are combined, the pin member (400) is prevented from being arbitrarily separated from the outer housing (100) or the inner housing (200).

The pin protrusion (420) may have any shape that is coupled with the pin member support member (241) and can be separated from the pin member support member (241) only by application of an external force. In the illustrated embodiment, the pin protrusion (420) is formed in the shape of a hook and can be hook-fitted with the pin member support member (241).

A plurality of pin projections (420) may be provided. The plurality of pin projections (420) are arranged to face each other with a pin space (411) therebetween, and may be respectively combined with a plurality of pin member support members (241). In the illustrated embodiment, the pin projections (420) are provided in pairs and are arranged spaced apart from each other in the left-right direction.

The pin protrusion (420) is formed on the outer periphery of the pin body (410). The pin protrusion (420) may be formed by protruding from a portion of the pin body (410) that extends flatly. In the illustrated embodiment, the pin protrusion (420) is formed by protruding outwardly in the width direction of the pin body (410), that is, on the left and right sides. The pin protrusion (420) extends in the height direction of the pin body (410), that is, in the vertical direction in the illustrated embodiment.

In the illustrated embodiment, the pin projection (420) includes a first pin extension (421), a second pin extension (422), and a third pin extension (423).

The first pin extension (421) forms a portion of the pin projection (420). The first pin extension (421) forms a side opposite to the outer housing (100) or the inner housing (200), the rear side in the illustrated embodiment.

The first pin extension (421) may extend at a predetermined angle with respect to the outer circumference of the pin body (410). In the illustrated embodiment, the first pin extension (421) extends at an obtuse angle with respect to the outer circumference of the pin body (410).

The second pin extension (422) constitutes another portion of the pin projection (420). The second pin extension (422) is located between the first pin extension (421) and the third pin extension (423).

The second pin extension (422) may extend at a predetermined angle with respect to the first pin extension (421). In the illustrated embodiment, the second pin extension (422) extends at an obtuse angle with respect to the first pin extension (421). In one embodiment, the second pin extension (422) may extend in the forward-backward direction.

The third pin extension (423) constitutes the remainder of the pin projection (420). The third pin extension (423) constitutes the other side, the front side in the illustrated embodiment, facing the outer housing (100) or the inner housing (200).

The third pin extension (423) extends at a predetermined angle with respect to the outer periphery of the second pin extension (422) and the pin body (410), respectively. In the illustrated embodiment, the third pin extension (423) extends at an obtuse angle with respect to the second pin extension (422) and the pin body (410), respectively.

At this time, the third pin extension (423) may be formed so that the protrusion length increases as it goes toward the rear. Additionally, the first pin extension (421) may be formed so that the protrusion length decreases as it goes toward the rear.

Accordingly, when the pin member (400) is moved toward the outer housing (100) and the inner housing (200), the third pin extension (423) is pressed inwardly to be deformed in shape and can be inserted into the pin member through-hole (242). When the movement of the pin member (400) continues and the first pin extension (421) is inserted into the pin member through-hole (242), the first pin extension (421) can be hook-coupled with the pin member support member (241).

The pin boss (430) constitutes another part of the outer shape of the pin member (400). The pin boss (430) is a part of the pin member (400) that is joined to the pin member joining hole (121). The pin boss (430) can be inserted and joined into the pin member joining hole (121).

The pin boss (430) may have a shape corresponding to the pin member joining hole (121). In the illustrated embodiment, the pin boss (430) is formed to have a cross section having a pair of straight lines and a pair of curved lines continuous with the pair of straight lines.

The pin boss (430) is continuous with the pin body (410). The pin boss (430) is continuous with one end of the pin body (410) in the extension direction, that is opposite the outer housing (100) or the inner housing (200), in the illustrated embodiment, the rear side.

The pin boss (430) is continuous with the pin grip portion (440). The pin boss (430) is continuous with one end of the pin grip portion (440) in the extension direction, that is, the front side in the illustrated embodiment, facing the outer housing (100) or the inner housing (200). The pin boss (430) is positioned between the pin body (410) and the pin grip portion (440) along the front-back direction.

At this time, the outer circumference of the cross-section of the pin boss (430) can be formed longer than the outer circumference of the cross-section of the pin body (410). Accordingly, as described above, the cross-sectional area of the pin boss (430) can be formed larger than the cross-sectional area of the pin body (410).

The pin grip portion (440) is a portion of the pin member (400) that is gripped by the worker. The pin grip portion (440) constitutes a side of the pin member (400) that is opposite to the outer housing (100) or the inner housing (200), in the illustrated embodiment, the rear side. The pin grip portion (440) is positioned to face the pin body (410) or the pin protrusion (420) with the pin boss (430) interposed therebetween.

The pin grip portion (440) may be exposed to the outside of the outer housing (100). That is, the pin grip portion (440) is not accommodated in the pin member joining hole (121). The worker may grip the pin grip portion (440) exposed to the outside of the outer housing (100) and pull it in a direction opposite to the outer housing (100) or the inner housing (200), i.e., toward the rear in the illustrated embodiment, thereby separating the pin member (400) from the outer housing (100) or the inner housing (200).

Referring again to FIG. 2, the discharge device (10) according to one embodiment of the present invention includes a fastening member (500).

The fastening member (500) connects the inner housing (200) and the installation member (300). The fastening member (500) is penetrated and connected to the fastening member receiving hole (232) and the fastening cavity (331), respectively.

As described above, the fastening member receiving hole (232) and the fastening cavity (331) can be exposed to the outside of the outer housing (100) only when they are arranged to overlap the pin member joining hole (121) by rotation of the outer housing (100).

Accordingly, it will be understood that when the outer housing (100) is rotated so that the pin-less joint hole (121) does not overlap with the fastening member receiving hole (232) and the fastening cavity (331), the fastening member (500) coupled therewith is also not exposed to the outside.

The fastening member (500) may be provided in any form that can couple the inner housing (200) and the installation member (300). In one embodiment, the fastening member (500) may be provided as a screw member. In the above embodiment, the fastening member (500) may be coupled or separated from the fastening member receiving hole (232) and the fastening hollow (331) along the extension direction thereof, i.e., the front-rear direction in the illustrated embodiment.

In addition, the water discharge device (10) according to an embodiment of the present invention can be connected to the inner housing (200) and the installation member (300) by the fastening member (500) on the upper side of the plate (P). Accordingly, the connection and separation of the fastening member (500) can be easily performed.

A plurality of fastening members (500) may be provided. A plurality of fastening members (500) may be respectively coupled to a plurality of fastening member receiving holes (232) and fastening cavities (331). In the illustrated embodiment, a pair of fastening members (500) are provided, and are respectively coupled to the inner housing (200) and the installation member (300) on the left and right sides.

Referring to FIGS. 12 to 21, each configuration of a water discharge device (10) according to another embodiment of the present invention is illustrated. In this embodiment as well, the water discharge device (10) includes an outer housing (100), an inner housing (200), an installation member (300), a pin member (400), and a fastening member (500).

In this embodiment, the inner housing (200) further includes an inner housing base (250). In addition, the pin member (400) further includes a pin groove (450).

Others, the outer housing (100), the installation member (300) and the fastening member (500) are the same as those of the discharge device (10) according to the above-described embodiment, and therefore, the description thereof will be replaced with the description of the discharge device (10) according to the above-described embodiment.

In the embodiments illustrated in FIGS. 15, 17 to 19, the inner housing (200) includes an inner housing body (210), an inner housing space (220), a fastening member coupling portion (230), a pin member coupling portion (240), and an inner housing base (250).

The inner housing body (210), the inner housing space (220), the fastening member joining portion (230), and the pin member joining portion (240) according to the present embodiment are identical in structure and function to those of the above-described embodiment. Accordingly, the following description will focus on the inner housing base (250).

The inner housing base (250) is coupled with the inner housing body (210) to support it. The inner housing base (250) is located between the plate (P) and the inner housing body (210).

In addition, the inner housing base (250) may be configured to support one side of the height direction of the extension housing (120), the lower end in the illustrated embodiment. Accordingly, the arbitrary falling of the extension housing (120) is prevented, so that the installation process of the water discharge device (10) can be easily performed.

The inner housing base (250) is coupled with one end of the inner housing body (210) facing the plate (P) in the extended direction, the lower end in the illustrated embodiment. A plurality of protrusions are formed on the one end of the inner housing body (210). A plurality of protrusions are also formed on the inner housing base (250), and can be coupled with each of the plurality of protrusions formed on the inner housing body (210).

In the illustrated embodiment, when the inner housing body (210) is rotated in one direction after being coupled with the inner housing base (250), the protrusions may be coupled with each other so that the inner housing body (210) and the inner housing base (250) may be coupled. Similarly, when the inner housing body (210) is rotated in another direction while in the coupled state, the protrusions may be released from each other so that the inner housing body (210) and the inner housing base (250) may be separated.

The inner housing base (250) may be any shape that can be detachably coupled to the inner housing body (210) and support the inner housing body (210). In the illustrated embodiment, the inner housing base (250) has a three-dimensional shape with an annular cross-section having a hollow formed therein and a height in the vertical direction.

Referring to FIGS. 20 and 21, a pin member (400) provided in a water discharge device (10) according to another embodiment of the present invention is illustrated. In the illustrated embodiment, the pin member (400) includes a pin body (410), a pin projection (420), a pin grip portion (440), and a pin groove (450).

The pin body (410) constitutes a part of the outer shape of the pin member (400). The pin body (410) is a part of the pin member (400) that penetrates the pin member through hole (242) and is positioned in the internal housing space (220).

The pin body (410) extends in the direction in which the pin member (400) is coupled with the outer housing (100) or the inner housing (200), in the forward and backward direction in the illustrated embodiment.

The pin body (410) may have a shape corresponding to the pin member through hole (242). In the illustrated embodiment, the pin body (410) is formed to have a cross section having a pair of straight lines and a pair of curved lines continuous with the pair of straight lines.

The pin body (410) is continuous with the pin projection (420). The pin projection (420) may be located at one end of the pin body (410) in the direction of extension, toward the outer housing (100) or the inner housing (200), and in the illustrated embodiment, at the outer periphery of the front end.

The cross-sectional area of the pin body (410) may be less than or equal to the cross-sectional area of the pin member through-hole (242). Accordingly, the pin body (410) may be pressed inward to be deformed and may penetrate the pin member through-hole (242). To this end, a pin space (411) is formed inside the pin body (410).

The pin space (411) is formed inside the pin body (410) to cushion the shape deformation in the inward direction of the pin body (410). The pin space (411) extends in the extension direction of the pin body (410), in the forward and backward direction in the illustrated embodiment. One side of the extension direction of the pin space (411), in the illustrated embodiment, the front side, is formed open.

The pin projection (420) is a portion that is combined with the pin member support member (241). As the pin projection (420) and the pin member support member (241) are combined, the pin member (400) is prevented from being arbitrarily separated from the outer housing (100) or the inner housing (200).

The pin protrusion (420) may have any shape that is coupled with the pin member support member (241) and can be separated from the pin member support member (241) only by application of an external force. In the illustrated embodiment, the pin protrusion (420) is formed in the shape of a hook and can be hook-fitted with the pin member support member (241).

A plurality of pin projections (420) may be provided. The plurality of pin projections (420) are arranged to face each other with a pin space (411) therebetween, and may be respectively combined with a plurality of pin member support members (241). In the illustrated embodiment, the pin projections (420) are provided in pairs and are arranged spaced apart from each other in the left-right direction.

The pin protrusion (420) is formed on the outer periphery of the pin body (410). The pin protrusion (420) may be formed by protruding from a portion of the pin body (410) that extends flatly. In the illustrated embodiment, the pin protrusion (420) is formed by protruding outwardly in the width direction of the pin body (410), that is, on the left and right sides. The pin protrusion (420) extends in the height direction of the pin body (410), that is, in the vertical direction in the illustrated embodiment.

In the illustrated embodiment, the pin protrusion (420) includes a first pin extension (421), a second pin extension (422), and a protrusion space (424).

The first pin extension (421) constitutes a portion of the pin projection (420). The first pin extension (421) is a flatly extended portion of the pin body (410), which is continuous with the upper and lower sides in the illustrated embodiment. The first pin extension (421) extends along the above portion of the pin body (410) and protrudes in the height direction.

The first pin extensions (421) may be provided in multiple numbers. The multiple first pin extensions (421) may face each other with a pin space (411) or a protrusion space (424) therebetween. In the illustrated embodiment, the first pin extensions (421) are provided in pairs and are spaced apart from each other in the vertical direction with a pin space (411) or a protrusion space (424) therebetween.

The first pin extension (421) is continuous with the second pin extension (422).

The second pin extension (422) constitutes another portion of the pin projection (420). The second pin extension (422) is continuous with a portion of the pin body (410) that extends roundly, the left and right sides in the illustrated embodiment. The second pin extension (422) extends along the portion of the pin body (410) and protrudes in the width direction.

A plurality of second pin extensions (422) may be provided. A plurality of second pin extensions (422) may face each other with a pin space (411) or a protrusion space (424) therebetween. In the illustrated embodiment, a pair of second pin extensions (422) are provided and are spaced apart from each other in the left and right directions with a pin space (411) or a protrusion space (424) therebetween.

The protrusion space (424) is a space defined by being surrounded by the first pin extension (421) and the second pin extension (422). The protrusion space (424) is configured to compensate for the shape deformation of the first pin extension (421) or the second pin extension (422) that is pressed inward when coupled to the pin member through hole (242) and the pin member joining hole (121).

The protrusion space (424) is connected to the pin space (411). The protrusion space (424) can compensate for the shape deformation of the pin body (410) or the pin protrusion (420) together with the pin space (411). One side in the longitudinal direction of the protrusion space (424), the front side in the illustrated embodiment, is formed open.

The pin grip portion (440) is a portion of the pin member (400) that is gripped by the worker. The pin grip portion (440) constitutes a side of the pin member (400) that is opposite to the outer housing (100) or the inner housing (200), in the illustrated embodiment, the rear side. The pin grip portion (440) is positioned to face the pin protrusion (420) with the pin body (410) interposed therebetween.

The pin grip portion (440) may be exposed to the outside of the outer housing (100). That is, the pin grip portion (440) is not accommodated in the pin member joining hole (121). The worker may grip the pin grip portion (440) exposed to the outside of the outer housing (100) and pull it in a direction opposite to the outer housing (100) or the inner housing (200), i.e., toward the rear in the illustrated embodiment, thereby separating the pin member (400) from the outer housing (100) or the inner housing (200).

The pin grip portion (440) may have a shape corresponding to the shape of the pin member joining hole (121). In the illustrated embodiment, the pin grip portion (440) has a circular cross-section and a disc shape having a thickness in the front-back direction. In the above embodiment, it will be understood that the pin member joining hole (121) formed in the extension housing (120) is also circular.

In the above embodiment, the pin grip portion (440) can be rotatably coupled to the pin member coupling hole (121).

In the illustrated embodiment, the pin grip portion (440) includes a pin grip surface (441).

The pin grip surface (441) is a portion of the pin grip section (440) that is exposed to the outside of the outer housing (100). The pin grip surface (441) may have a shape corresponding to the shape of the outer periphery of the extension housing (120). In the illustrated embodiment, the pin grip surface (441) may be formed into a curved surface like the extension housing (120). In the above embodiment, the curvature of the pin grip surface (441) may be the same as the curvature of the extension housing (120).

A pin groove (450) is formed inside the pin grip surface (441).

The pin groove (450) is a space into which a member (not shown) for rotating the pin member (400) is inserted. The pin groove (450) is formed by being sunken into the pin grip surface (441). The pin groove (450) may have any shape into which the member (not shown) can be inserted. In the illustrated embodiment, the pin groove (450) is formed to have a height in the vertical direction and a depth in the front-back direction.

At this time, the pin groove (450) may be formed so that the degree of its depression decreases as it goes toward the end in the height direction. In other words, the pin groove (450) may be most deeply depressed at the center portion in the height direction. Accordingly, when the member (not shown) inserted into the pin groove (450) is rotated, the pin member (400) can be easily rotated. A detailed description thereof will be given later.

Referring to FIGS. 22 to 27, a process in which a discharge device (10) according to one embodiment of the present invention is combined with a plate (P) is illustrated as an example.

First, the installation member (300) is coupled to the insertion hole (H) of the plate (P) (①). Accordingly, the lower part of the installation member (300) penetrates the insertion hole (H) and is positioned on the lower side of the plate (P), and the upper part of the installation member (300) is supported by the plate (P).

Next, the inner housing (200) is penetrated into the extension housing (120) and moved downward together with the extension housing (120) to be coupled with the installation member (300) (②). At this time, the inner housing (200) can be pre-coupled with the outlet housing (110). The extension housing (120) can be positioned lower than the inner housing (200) and the outlet housing (110) coupled thereto.

The inner housing (200) and the outlet housing (110) combined therewith may be moved downwards to be combined with the installation member (300) and at the same time surrounded by the extension housing (120). The lower end of the inner housing body (210) may be supported by a plate (P).

Next, the extension housing (120) is rotated so that the fastening member connecting portion (230) and the fastening member connecting member (330) are exposed to the outside, so that the fastening member (500) connects the inner housing (200) and the installation member (300) (③). At this time, the water discharge housing (110) is connected to the inner housing (200), and it will be understood that the water discharge housing (110) is maintained in a preset direction regardless of the rotation of the extension housing (120).

Specifically, as illustrated in FIG. 23, the extension housing (120) is rotated in either a clockwise or counterclockwise direction so that one of the fastening member joining portions (230) (and the fastening hollow (331) overlapping it) overlaps the pin member joining hole (121) along a horizontal or radial direction. The fastening member (500) is joined to one of the fastening member joining portions (230) (and the fastening hollow (331) overlapping it) through the pin member joining hole (121).

In addition, as illustrated in FIG. 25, the extension housing (120) is further rotated in either the clockwise or counterclockwise direction so that another fastening member joining portion (230) (and the fastening hollow (331) overlapping it) is arranged to overlap the pin member joining hole (121) along the horizontal or radial direction. The fastening member (500) is joined with the other fastening member joining portion (230) (and the fastening hollow (331) overlapping it) through the pin member joining hole (121).

Finally, the extension housing (120) is rotated so that the pin member joining portion (240) is exposed to the outside, so that the pin member (400) joins the inner housing (200) and the extension housing (120) (④).

Specifically, as illustrated in FIG. 26, the extension housing (120) is rotated in either a clockwise or counterclockwise direction so that the pin member coupling portion (240) overlaps the pin member coupling hole (121) along a horizontal or radial direction. The pin member (400) is coupled to the pin member coupling portion (240) through the pin member coupling hole (121). As described above, the pin member coupling portion (240) is located at the rear side of the water discharge device (10).

Accordingly, as shown in Fig. 27, the pin member (400) is not exposed to the outside on the front side of the discharge device (10). Accordingly, when the discharge device (10) is normally used, the pin member (400) is not exposed to the outside.

In addition, since the fastening member (500) is also surrounded by the extension housing (120) and is not exposed to the outside, the appearance of the discharge device (10) can be maintained attractively.

Referring to FIGS. 28 to 30, a process of combining a water outlet device (10) according to another embodiment of the present invention is illustrated as an example. In FIGS. 28 to 30, only the process of combining a pin member (400) with an outer housing (100) and an inner housing (200) is illustrated, but it will be understood that a process of combining an outer housing (100), an inner housing (200), an installation member (300), and a fastening member (500) is performed prior to the above process.

Referring to Fig. 28, the pin member (400) is moved from the rear side of the outer housing (100) and the inner housing (200) toward the front side. At this time, it will be understood that the pin member joining hole (121) and the pin member joining portion (240) are arranged to overlap each other along the front-back direction.

Referring to Fig. 29, the pin member (400) is connected to the outer housing (100) and the inner housing (200) by penetrating through the pin member connecting hole (121) and the pin member connecting portion (240), respectively. In the above state, the pin protrusion (420) is arranged so that the width in the left-right direction is shorter than the length in the up-down direction.

Referring to FIG. 30, the pin member (400) is rotated in either a clockwise or counterclockwise direction. It will be understood that the rotation may be performed by inserting any member into the pin groove (450).

Accordingly, the pin projection (420) is arranged so that the width in the left-right direction is longer than the length in the up-down direction, and can be supported by the pin member support member (241). That is, in the above state, the pin member support member (241) is positioned between the second pin extension portion (422) and the pin grip portion (440).

Accordingly, the pin member (400) is not arbitrarily separated from the outer housing (100) or the inner housing (200).

Meanwhile, in the above state, the pin grip surface (441) can be arranged to have the same curvature as the outer surface of the extension housing (120). Accordingly, the pin grip surface (441) can form a smooth curved surface without protruding or sinking compared to the outer surface of the extension housing (120).

Accordingly, not only is the pin member (400) located on the rear side not exposed to the user during normal use, but the appearance of the water outlet device (10) can be maintained attractively even when the pin member (400) is exposed to the user.

Although the embodiments of the present invention have been described, the spirit of the present invention is not limited to the embodiments presented in this specification, and those skilled in the art who understand the spirit of the present invention will be able to easily suggest other embodiments by adding, changing, deleting, or adding components within the scope of the same spirit, but this will also be considered to fall within the spirit of the present invention.
