Abstract

PROBLEM TO BE SOLVED: To wash a nozzle body part without affecting the jetting of private part washing water and prevent sewage adhesion by distributing washing water into jetting outlet discharge and washing nozzle outer peripheral part washing, and providing an interference prevention means for preventing interference of discharge water and nozzle outer peripheral part washing water from an jetting outlet. SOLUTION: The pipeline 23 of a flow control valve 3 is branched into branch pipelines 21, 22 which are connected to a washing chamber 2 and a washing nozzle 1 respectively. A jetting outlet is provided on the edge on the washing nozzle 1, and a rib 1b preventing water from a washing chamber 2 on a root side rather than the jetting outlet from being poured on the jetting outlet is provided. The washing chamber 2 reflects the washing water discharged from the nozzle body 1, which is washed. Hot water is supplied on the outer periphery of the nozzle body 1 as soon as proper hot water is jetted from the jetting outlet of the nozzle body 1, since hot water supplied on the outer periphery of the nozzle body 1 from the rib is not interfered with the washing water from the jetting outlet, malfunction such as washing water scattering is eliminated, and the washing water is very sanitary without mixing the washing water for private part washing with sewage water.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing apparatus such as a toilet or bidet for washing a part to be washed after stool.

[0002]

2. Description of the Related Art Conventionally, Japanese Patent Publication No. 61-45737 has
There is disclosed a sanitary washing device that discharges cleaning water to a main body side of a cleaning device at an early stage of discharge of cleaning water, discharges cold remaining water, and cleans a nozzle.

Japanese Patent Publication No. 43101/1994 discloses a sanitary washing device in which a notch is provided in an upper portion of a nozzle cylinder, and the body of the nozzle body is washed by water pressure when the nozzle body extends. .

[0004]

[Problems to be solved by the invention]
In the device disclosed in Japanese Patent No. 45737, washing is performed before the start of use irrespective of the possibility that the soil is most likely to be dirty during use. ing. Therefore, there is a case where the stain cannot be removed even when the nozzle cleaning is performed.

[0005] In addition, in Japanese Patent Publication No. 1-343101, the nozzle is washed with water leaked when the nozzle body slides, so that the amount of water is insufficient and the nozzle cleaning is insufficient. It is hard to say. If the leaked water is increased, it may interfere with the jetted water from the nozzle tip, and the washing water may scatter. Furthermore, since the cleaning water heated by the heat exchanger is used for nozzle cleaning, the hot water tank is drained quickly in the case of a hot water storage type heat exchanger, and the amount of cleaning water is insufficient in the case of the instantaneous type heat exchanger. , Washing feeling is unsatisfactory.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to keep the nozzle clean at all times by cleaning the nozzle body even during local cleaning so as to make it difficult for dirty water to adhere. Another object of the present invention is to provide a sanitary washing device in which the washing water does not affect the jet of the local washing water.

A second object of the present invention is to provide a sanitary washing apparatus in which the washing nozzle is washed with water, so that the hot water in the heat exchanger is used only for local washing. A third object of the present invention is to provide a sanitary washing apparatus in which the flow rate adjusting means provided for protecting the heat exchange tank is simplified and cost is reduced.

[0008]

In order to solve the above problems, according to the first aspect of the present invention, a cleaning device main body and a part to be cleaned of a user using the cleaning device main body are cleaned. A cleaning nozzle provided with a jet port for discharging water at a tip thereof, cleaning water supply means for supplying cleaning water to the cleaning nozzle, cleaning water from the cleaning water supply means for discharging the jet port, and cleaning the outer periphery of the cleaning nozzle And a distributing means for distributing the water to the nozzles, and an interference preventing means for preventing interference between the discharge water from the jet port and the cleaning water at the nozzle outer peripheral portion. Since the cleaning water does not interfere with the cleaning water, there is no problem that the cleaning water scatters. In addition, sewage does not mix with the washing water for local washing,
Can be washed safely. According to the first aspect of the present invention, if the interference preventing means is formed by a rib protruding from the outer periphery of the ejection port, it can be realized with a simple configuration.

According to the third aspect of the present invention, when the distribution means is constituted by a flow path switching valve for selectively supplying water for discharging the jet port and for cleaning the outer peripheral portion of the nozzle, Since the cleaning of the outer periphery of the nozzle is not performed when the local cleaning is performed, the cleaning water for performing the local cleaning does not mix with the sewage, so that the cleaning can be performed safely.

[0010] In the invention according to claim 4, the cleaning device main body, a tank for storing water from a water supply source, and a pressure provided upstream of the tank are adjusted so that a water supply pressure to the tank is within a predetermined pressure range. A pressure adjusting means, a heating means for heating water stored in the tank, a cleaning nozzle provided at a tip thereof with a jet port for discharging cleaning water to a portion to be cleaned of a user using the cleaning device main body, In a sanitary washing apparatus comprising washing water supply means for supplying hot water in the tank to a washing nozzle, the pressure adjusting means is constituted by a distribution valve, one of the distribution valves washing the washing nozzle and the other washing the washing nozzle. Since the cleaning unit is connected to the cleaning unit, the local cleaning is performed with hot water, and the outer peripheral portion of the nozzle is cleaned with water, so that there is no energy loss. Further, since the heating capability of the heating means can be reduced, the size can be reduced.

According to a fifth aspect of the present invention, there is provided an interference preventing means for preventing interference between the water discharged from the jet port and the cleaning water for cleaning the cleaning nozzle, so that the water discharged from the jet port and the outer peripheral portion of the nozzle are provided. Since the washing water does not interfere with the washing water, there is no problem that the washing water is scattered. In addition, dirty water is not mixed with the cleaning water for performing local cleaning, so that the cleaning can be performed safely.
