In a nozzle assembly 100 for a bidet according to an embodiment of the present disclosure, a nozzle unit 130 is configured to make a curved movement so that a space occupied by the nozzle assembly 100 for a bidet in a bidet main body is reduced.
Referring to
The movement guide member 110 may be provided to correspond to a shape of the nozzle unit 130, and, preferably, has a curved shape. Thus, as described hereinafter, the nozzle unit 130 may be guided to make a curved movement along the movement guide member 110.
The nozzle unit 130 may make a curved movement along the movement guide member 110, and may include a cylinder member 131 in which a water supply hose 133 connected to a water source (not shown) is installed.
That is, as in the illustrated embodiment, the nozzle unit 130 may be mounted on the movement guide member 110 and installed to be movable in a forward/backward direction along the movement guide member 110. Here, since the movement guide member 110 has a curved shape, the nozzle unit 130 may make a curved movement in the forward/backward direction.
Here, in a case in which the movement guide member 110 does not have a curved shape, the nozzle unit 130 may be provided to have a curved shape to make a curved movement.
The cylinder member 131 may be formed of generally used stainless steel, but a material of the cylinder member 131 is not limited thereto. and various modifications may be made.
The nozzle unit 130 may include the cylinder member 131 with a hollow formed therein and the water supply hose 133 disposed in the hollow of the cylinder member 131. The water supply hose 133 may be connected to a water source and may supply cleaning water to the nozzle unit 130.
Here, the water supply hose 133 may be formed as a flexible pipe, and in this case, a rubber hose, a fabric hose, or a silicon hose may be formed of a synthetic resin pipe. However, a material of the water supply hose 133 is not limited thereto, and may be variously modified.
The driving unit 150 may be connected to the nozzle unit 130 and provide power for the nozzle unit 130 to move along the movement guide member 110.
Here, there are no limitations in a structure or type of the driving unit 150, and various types of driving units may be applied as long as they may be able to move the nozzle unit 130 in the forward/backward direction along the movement guide member 110.
In this manner, in the nozzle assembly 100 for a bidet according to an embodiment of the present disclosure, since the movement guide member 110 is provided to form a curved line or the nozzle unit 130 is provided to have a curved shape, the nozzle unit 130 may make a curved movement, and thus, the nozzle unit 130 may move even in a small space. Thus, in a case of a bidet integrated with a toilet, a shallow recess may be formed in a toilet unit to install a bidet unit therein, and in case of a bidet toilet seat as a conventional bidet, a height of a bidet main body may be lowered.
The cylinder member 131 of the nozzle unit 130 may have a curved shape corresponding to the movement guide member 110.
When the nozzle unit 130 has a curved shape corresponding to the movement guide member 110, the nozzle unit 130 may smoothly make a curved movement along the movement guide member 110. Also, since the nozzle unit 130 has the curved shape, an area occupied by the bidet unit may be reduced.
However, the shape of the cylinder member 131 is not limited to the illustrated embodiment, and the cylinder member 131 may be modified to various shapes as long as the nozzle unit 130 makes a curved movement.
Meanwhile, since the water supply hose 133 is formed of a flexible material, the water supply hose 133 may be installed to be easily deformed according to a shape of the cylinder member 131 within the curved cylinder member 131.
Thus, even in a case in which the cylinder member 131 is formed to have a curved shape to make a curved movement, a flow channel in which cleaning water is supplied may be easily manufactured.
Meanwhile, as illustrated in
That is, the nozzle tip 135 is provided at a font end of the cylinder member 131 to dispense cleaning water to private parts of a user. The ejection hole 135a may be formed to communicate with the connector 136 (to be described hereinafter) and dispense cleaning water supplied through the connector 136. Here, the nozzle tip 135 may be detachably connected to the cylinder member 131.
The connector 136 may be connected to the nozzle tip 135 in such a manner that the connector 136 communicates with the ejection hole 135a, and may be inserted within the cylinder member 131. The connector 136 may be insert-coupled to one end of the water supply hose 133. Thus, the connector 136 may be connected to the water supply hose 133 connected to a water supply pipe, and cleaning water supplied from the water supply pipe may move up to the ejection hole 135a.
In this manner, according to an embodiment of the present disclosure, the connector 135, to which the water supply hose 133 is connected, is provided at a front end of the cylinder member 131, and the water supply hose 133 may be connected to the interior of the cylinder member 131.
Meanwhile, the connector 136 may be provided in plurality, and the water supply hose 133 may be provided in plurality within the cylinder member 131 to form a plurality of flow channels.
That is, in forming a cleaning water flow channel within the cylinder member 131 in the nozzle unit 130, the water supply hose 133 connected to the water source, not a plastic injection-molded product, is directly installed within the cylinder member 131 to form a cleaning water flow channel, whereby the water supply hose 133 may be easily installed within the cylinder member 131 manufactured to have a curved shape, and a plurality of water supply hoses 133 may be easily installed within the cylinder member 131.
In this manner, since a plurality of cleaning water flow channels are formed within the cylinder member 131 by the plurality of water supply hoses 133, the nozzle unit 130 may form various water streams. That is, since a plurality of cleaning water flow channels are formed, a wide water stream, a linear water stream, and a water stream for nozzle cleaning may be formed according to each of connection holes and a size of the water supply hose 133 connected to each of the connection holes, and a velocity of water supplied to the water supply hose 133.
The nozzle unit 130 may include a connector member 137 having a through hole member 137b coupled to the other end of the cylinder member 131 and allowing the water supply hose 133 to pass therethrough, to fix the water supply hose 133.
That is, as illustrated in
Also, the connector member 137 may have a guide protrusion 137c formed to be inserted into a guide groove 111 of the movement guide member 110, prevent release of the cylinder member 131, and guide movement of the cylinder member 131.
In the movement guide member 110, the guide groove 111 may be formed in a direction in which the nozzle unit 130 moves, and, as in the illustrated embodiment, the guide groove 111 may be formed in plurality. The guide protrusion 137c of the connector member 137 may be installed to be inserted into a position corresponding to the guide groove 111 to guide a slidable movement of the cylinder member 131 when the cylinder member 131 moves in a forward/backward direction and prevent release of the cylinder member 131 from the movement guide member 110.
However, the formation and the number of the guide protrusions 137c and the guide groove 111 are not limited to the illustrated case, and may be variously modified.
Meanwhile, the nozzle assembly 100 for a bidet according to an embodiment of the present disclosure may further include a nozzle duct unit 170 fixedly installed at a front end of the movement guide member 110 to protect the nozzle unit 130 and allowing the nozzle unit 130 to pass therethrough to guide movement of the nozzle unit 130.

Also, the nozzle duct unit 170 may serve as a stopper fixedly installed at the front end of the movement guide member 110 to allow the connector member 137 connected to the other end of the cylinder member 131 to be caught thereby, thus limiting movement of the cylinder member 131.
The nozzle duct unit 170 may include a self-cleaning member 171 having a cleaning water inlet 172 to dispense cleaning water to the nozzle tip 135 provided in the nozzle unit 130 when the nozzle unit 130 is in the original position.
That is, when the nozzle unit 130 is in the original position, the cleaning water inlet 172 may be connected to communicate with an upper portion of the nozzle tip 135, and the cleaning water inlet 172 may be connected to the water source. Thus, the self-cleaning member 171 may remove fecal matter from the nozzle tip 135.
The driving unit 150 may include a connection member 151 having one side fixedly coupled to the nozzle unit 130, a winding member 153 connected to the other side of the connection member 151 and allowing the connection member 151 to be wound therearound or drawn out according to rotation, and a driving motor 155 connected to the winding member 153 and providing rotational force to the winding member 153.
Here, the connection member 151 may be provided as a belt gear 151 having one side fixedly coupled to a lower end of the connector member 137. Hereinafter, the connection member and the belt gear will be denoted by the same reference numeral 151 for the purposes of description.
As an installation protrusion 151 formed at one end of the belt gear 151 is insertedly installed in the through hole member 137b formed at a lower portion of the connector member 137, one end of the belt gear 151 and the connector member 137 may be fixedly coupled.
The other side of the connection member 151 provided as the belt gear 151 may be wound around the winding member. The winding member 153 may include a spur gear 154, and the spur gear 154 and the belt gear 151 may be engaged with each other.
The spur gear 154 may be connected to the driving motor 155, and may be forwardly or backwardly rotated according to an operation of the driving motor 155 to wind or draw out the belt gear 151, and as the belt gear 151 is wound or drawn out, a length of extension of the nozzle unit 130 may be adjusted.
The nozzle assembly 100 for a bidet according to an embodiment of the present disclosure may be adjusted by multiple steps in such a manner that a length of extension of the nozzle unit 130 is lengthened from a lower step to a higher step, and as an example,
Referring to
Meanwhile, a first lead-in rotation angle a′ for changing a length of extension of the nozzle unit 130 from the second step to the first step, a second lead-in rotation angle b′ for changing a length of extension of the nozzle unit 130 from the third step to the second step, and a third lead-in rotation angle c′ for changing a length of extension of the nozzle unit 130 from the fourth step to the third step may be the opposite in direction and the same in values with respect to the first exit-out rotation angle a, the second exit-out rotation angle b, and the third exit-out rotation angle c.
Conversely, the first exit-out rotation angle a may be greater than the second exit-out rotation angle b, and the second exit-out rotation angle b may be greater than the third exit-out rotation angle c. That is, the exit-out rotation angle may be reduced toward a higher step.
In addition, a difference between the first exit-out rotation angle a and the second exit-out rotation angle b may be greater than a difference between the second exit-out rotation angle b and the third exit-out rotation angle c. In other words, a decrease of the exit-out rotation angle may be reduced toward a higher step.
Accordingly, intervals a″, b″, and c″ between ejection positions of the nozzle by stages may be uniform.
