Description

Nozzle assembly in hot water washer{NOZZLE ASSEMBLY IN BIDET}

Embodiments of the invention relate to nozzle assemblies used in hot water cleaners.

In general, a bidet (bidet) is widely used as a toilet seat in a lodging facility or a general home because it is located on the toilet seat of the toilet. The bidet is configured to remove feces-related dirt from the user's body by spraying hot water over the anus and/or the user's anus through the nozzle assembly after the user's toilet. In this case, the nozzle assembly has flow control valves, cylinders and nozzle tips that engage with each other. The cylinders receive cleaning water from the flow control valve and deliver it to the nozzle tips.

The nozzle tips may be described as being divided into first nozzle tips and second nozzle tips. The first nozzle tips may be embedded in the cylinders so as to be partially filled in the cylinders, respectively, located at the leading ends of the cylinders. Since the cylinders and the first nozzle tips have wash water flow paths, the first nozzle tips can re-introduce the wash water from the central region of the cylinders through the inner wash water flow path to the tip of the cylinders. In addition, the first nozzle tips have air flow paths along with wash water flow paths.

Thus, the first nozzle tips, based on Bernoulli's principle, continue to flow external air to the tip of the cylinders through the air flow paths using the speed of the rinse water in the rinse water flow paths and/or the tips of the cylinders. Can be introduced. Through this, the first nozzle tips can inject air into the washing water at the leading ends of the cylinders, and the cylinders can inject air intake washing water to the user using the first nozzle tips.

The first nozzle tips are disclosed in detail in Korean Registered Utility Model Publication No. 20-0432068. Alternatively, since the nozzle assembly is contaminated by the toilet-related dirt from the user's body during use of the user's bidet, the second nozzle tips can surround the cylinders at the tips of the cylinders to be detachable from the cylinders after their useful life. have. The second nozzle tips are disclosed in detail in Korean Patent Publication No. 10-2009-0127708.

However, since the first nozzle tips are embedded in the cylinders at the tip of the cylinders, the size of the cylinders is smaller than that of the cylinders, and thus, when installed in the cylinders, it can place an administrative burden on the operator. In addition, since the first nozzle tips and the second nozzle tips are exposed around the user's anus and/or local area, the service life is irregular, and the reduction of the cleaning cycle or the increase in replacement cost is borne by the user.

The problem to be solved by the present invention is to be located around the cylinders in the hot water washer, to simplify the flow paths of the washing water and air, respectively extending from the cylinders, and to be suitable for confining the flow paths of the washing water and air to a predetermined space. It is to provide a nozzle assembly including a nozzle module.
