Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device that is installed in a flush toilet bowl and has a function of cleaning private parts and a function of drying with warm air after cleaning.

[Conventional technology]

Conventionally, sanitary cleaning devices with the above functions have a casing fixed to the rear side of the toilet bowl body, and are equipped with a nozzle device for cleaning and a hot air fan for drying inside, and a control unit that blows out hot air after cleaning. The structure is such that drying is carried out using

This hot air fan has a fan motor and impeller placed in the main body, a blowout duct that opens toward the toilet bowl, and a heater for heating and a sensor for temperature detection placed inside the duct. .

FIG. 6 is a schematic cross-sectional view of a conventional hot air blowing duct installation structure, in which 50 is a casing of a sanitary cleaning device fixed to a toilet main body 51, 52 is a toilet seat rotatably pivoted to this casing 50, and 53 is a duct communicating with the hot air fan 54.

Since this duct 53 is located under the toilet seat 52, at least the blowing end side of the duct 53 is set horizontally or upwardly so that warm air is directed to the drying position when a person sits on the toilet seat 52. It is structured as follows.

[Problem that the invention attempts to solve]

However, if the spouting portion of the duct 53 is directed upward, sewage or the like is likely to enter the duct 53 during defecation or cleaning with the nozzle device.

Since the duct 53 has a built-in heater and the like as described above, there is a possibility that troubles may occur due to sewage entering from the tip of the duct. Furthermore, if dirt enters the duct 53, it may cause problems such as emitting a strange odor during the drying process, which is not desirable for a sanitary cleaning device.

The purpose of this invention is to prevent sewage and filth from entering the duct that blows out hot air for drying in sanitary cleaning equipment equipped with cleaning and drying functions, to prevent troubles from occurring and the release of strange odors, and to prevent the user from experiencing problems. The purpose is to direct hot air to the location to be dried.

[Means and actions for solving problems]

The present invention provides a sanitary cleaning device in which a nozzle device and a hot air fan are built in and placed at the rear of the toilet bowl body, and the hot air blowing end of the hot air fan is located at the bottom of the toilet seat, and the hot air fan is connected to the hot air fan. The hot air ejecting end side of the housing that defines a hot air flow path has a duct part that slopes downward in the direction of flow of the hot air, and a duct part that is continuous with the duct part and faces the inside of the duct part that slopes downward in the direction of flow of hot air. The internal flow path is divided into upper and lower parts so that the flow path is oriented horizontally or upwardly, and a rectifying section is provided with a rectifying plate oriented horizontally or upwardly in the flow direction of the hot air. .

The hot air from the hot air fan flows downward through the duct section, but the downstream rectifying section that is continuous with this duct section has a rectifying plate installed therein that directs the hot air in the direction of flow. Since it is oriented horizontally or upwardly, the warm air finally released from the housing flows horizontally or diagonally upwardly under the toilet seat.
Further, even if wash water, sewage, etc. enter from the rectifying section, the upstream side of the duct section is inclined upward, so that the intruding water and other foreign substances are prevented from entering.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 is a perspective view of a flush toilet equipped with a sanitary cleaning device A according to the present invention, in which B is the toilet body, C is a flush water tank that stores flush water for flushing the toilet, D and E.
are the toilet seat and toilet lid.

FIG. 2 is a plan view of the inside of the sanitary cleaning device A, in which 1 is a mounting board for fixing built-in equipment, 30 is a hot water tank for heating and storing cleaning water, and 31 is this hot water storage tank 3.
32 is a nozzle body 33 that spouts heated cleaning water to private areas.
34 is an operating section in which a switch for performing operations such as washing and drying is arranged.

Furthermore, 2 is a warm air fan fixed to the right end of the mounting board 1, which has a motor 3 and an impeller 4 supported by upper and lower housings 5 and 6, and heats the air from the impeller 4 to the front edge of the mounting board 1. It forms a wind flow path.

FIG. 3 is an exploded perspective view of the upper and lower housings 5 and 6. Both housings 5 and 6 have spiral bodies and form duct portions 7 and 8 that open at the front edge of the mounting board 1 when superimposed. There is.

The lower housing 6 has a holed flange 9 formed at its lower portion through which a fixing screw to the mounting board 1 is inserted, and the bottom surface of the duct portion 8 is provided so as to be inclined downward.

The duct part 7 of the upper housing 5 is connected to the lower housing 6
A portion corresponding to and overlapping with the duct portion 8 is formed to be inclined downward similarly to the lower housing 6,
Further, a rectifying section 10 extends from the terminal end of the duct section 8.
are provided integrally.

This rectifying section 10 forms a hot air jet flow path that is continuous with the duct sections 7 and 8 of the upper and lower housings 5 and 6.
2 are provided. The current plates 11 and 12 are inclined upward as shown in FIG.
These rectifying plates 11 and 12 direct the jet flow downward from
The toilet seat D is configured to change its direction upward and forcibly blow out hot air from the lower part of the toilet seat D toward the local area.

In addition, the duct portions 7 of both housings 5 and 6,
8 is equipped with a coil heater 20 that heats the forced airflow from the impeller 4, a temperature sensor 21 that detects the temperature of the hot air, etc., and the amount of heat generated by the coil heater 20 is controlled by a switch and a temperature adjustment dial on the operating section 34. It is adjustable, and the temperature of the hot air is controlled by a temperature sensor 21 to prevent overheating.

In the above configuration, when the hot air fan 2 is operated to blow out hot air from the rectifier 10, the hot air flows from below the toilet seat D due to the horizontal or upward inclination of the rectifier plates 11 and 12 located at the blowing ends. The flow is directed upward so as to escape, allowing for drying after washing.

In addition, the outlet side tips of the current plates 11 and 12 are moved so that the upper current plate 11 is placed behind the top of the upper housing 5, and the lower current plate 12 is placed behind the upper current plate 11, so that the flow path of the sewage splashes. The shape is such that it is difficult for splashes to enter as they are roughly aligned.

Even if cleaning water or sewage splashes during cleaning and enters the inside of the hot air fan 2 from the rectifier 10,
The downward inclination of the duct portions 7 and 8 allows this to be quickly discharged. In other words, since the tips of the duct parts 7 and 8 are inclined downward, foreign matter entering from the rectifying part 10 cannot ascend up the duct parts 7 and 8, and is pushed back by the hot air jetting out. is discharged from.

In this way, by slanting the duct parts 7 and 8 downward, it is possible to prevent the intrusion of foreign matter and keep the inside of the hot air jet flow path clean. can be used for. In addition, since the spouting end is provided with a rectifier 10 that changes the direction of the hot air flow upward, even if the spouting end is located below the toilet seat D, hot air can be supplied to private areas and drying can be ensured. be able to.

[Effect of idea]

This invention can prevent foreign matter from entering the flow path of the hot air fan that performs drying, so it can always operate stably without causing trouble to the equipment, and can be used hygienically without emitting any strange odors. can.
