Description

Bidet nozzle assembly < RTI ID = 0.0 >

The present invention relates to a nozzle assembly for a bidet configured to perform a curved movement of a nozzle, in which a nozzle and a guide portion of a housing for guiding the nozzle are curved downward so that a curve can be moved in forward and backward directions of the nozzle, To a bidet nozzle assembly that can be installed in a space.

In the bidet nozzle assembly according to the present invention, the flow control valve is directly connected to a flow path (cleaning flow path, bidet flow path) formed inside the nozzle without using a hose or the like, and the sleeve of the flow control valve The present invention relates to a bidet nozzle assembly for preventing water from penetrating into a motor of a flow rate control valve even if the flow rate control valve is directly coupled to the nozzle by forming a bypass hole for discharging water.

The nozzle assembly for a bidet is mounted on a bidet in the case of a bidet-integrated bidet and mounted on the bidet body in the case of a detachable bidet. The nozzle assembly includes a nozzle capable of cleaning by spraying water onto a local portion of the body. .

The nozzle provided in the bidet nozzle assembly is kept in a waiting position inside the bidet when not in use. When the user places the toilet on the toilet seat of the bidet and then makes a cleaning instruction, the user places the nozzle in the injection position And the nozzle moved to the injection position injects the water supplied from the water supply source to the local portion of the user so that the user's local portion is cleaned.

However, in the conventional bidet nozzle assembly, since the nozzle has a straight shape and is inclined downward, the nozzle necessarily moves linearly downward in the oblique direction.

Therefore, in the case of the conventional bidet assembly, there is a problem that a comparatively large space is required for the movement of the nozzle in the bidet body in the pot body integrated bidet and the bidet body in the pot body detachable bidet.

For this purpose, for example, in the case of a pottery integrated bidet, a deep groove must be formed in the toilet portion or a height of the bidet portion must be high, and in the case of the detachable bidet, the height of the bidet body must be high.

On the other hand, in the conventional bidet nozzle assembly, since the flow rate control valve for controlling the water supply is not directly connected to the nozzle but connected by connecting means such as a hose, the structure is complicated and malfunction due to disconnection occurs There is also a problem that the space is widely occupied at the time of assembly.

SUMMARY OF THE INVENTION The present invention has been conceived to solve the above-described problems, and it is an object of the present invention to provide a nozzle and a guide portion of a housing for guiding the nozzle, which are curved downward, There is a first purpose in doing so.

In the present invention, the flow control valve is directly connected to the flow path (cleaning flow path, bidet flow path) formed inside the nozzle without using a hose or the like, and a bypass hole for discharging water is formed in the sleeve of the flow control valve Thereby, even if the flow control valve is directly coupled to the nozzle, the water is prevented from penetrating the motor of the flow control valve at all.

To achieve the above object, in the present invention,

A nozzle having a water jetting port coupled to the tip thereof and having a cleaning flow path and a bidet flow path therein; A flow regulating valve coupled to the rear of the nozzle to be driven by a motor to control an internal flow path of the nozzle; And a housing having a gear accommodating portion for accommodating the gear, a gear driving motor for moving the nozzle, a flow control valve, and a gear, the bidet nozzle having a guide portion for guiding the support and path of the nozzle, In an assembly,

The guide portion of the housing for guiding the nozzle also has a shape corresponding to the nozzle, that is, it is curved downward, so that when the nozzle is moved forward and backward, And,

Wherein the flow control valve comprises: a valve body coupled to a rear end of the nozzle and having an accommodation space therein; A stator having through holes for supplying a bidet passage, a cleaning passage, and a cleaning passage; A shaft coupled to an axial end of the motor; A rotator coupled to transmit the rotational force of the shaft and connected to the stator such that the stator flow path is selected from among a bidet, a washing, and a washing mode when the stator is rotated on a surface of the stator; A spring elastically connected between the shaft and the rotator so that the rotator is brought into close contact with the surface of the stator; And a sleeve coupled to a rear end of the valve body such that the shaft is coupled to the inside of the valve body.

In order to prevent water leakage, the sleeve has a body to be coupled to the valve body, a body coupled to a rear end of the body, And a wing portion that is coupled to penetrate,

A through hole is formed in a longitudinal direction at a lower portion of the body, and a bypass hole communicating with the through hole is formed in the vane portion in a radial direction.

Since a rack of an elastic material is coupled to the gear at the rear end of the nozzle, when the gear driving motor is operated, rotational force is transmitted to the nozzle via the gear and the rack. And the rotational motion of the motor may be configured to be changed to a linear motion of forward and backward with respect to the nozzle and the flow rate control valve.

As described above, in the present invention,

The nozzle and the guide portion of the housing for guiding the nozzle are curved downwardly so that the curved movement can be performed at the time of forward and backward movement of the nozzle so that the nozzle can be installed in a narrow space. A shallow groove can be formed or a height of the bidet portion can be lowered, and in the case of the detachable bidet, the height of the bidet body can be lowered.

In the present invention, the flow control valve is directly connected to the flow path (cleaning flow path, bidet flow path) formed inside the nozzle without using a hose or the like, and a bypass hole for discharging water is formed in the sleeve of the flow control valve Thus, even if the flow control valve is directly coupled to the nozzle, water is prevented from penetrating the motor of the flow control valve at all. Therefore, it is possible to prevent the electric system such as the motor from being damaged or malfunction due to electric leakage.
