TECHNICAL FIELD The present invention relates to a human body local cleaning device, and more particularly to a human body local cleaning device having an integrally constructed toilet seat in which a toilet seat portion on which a user is seated and a main body portion that accommodates functional parts are configured. Background art

A human body local washing apparatus that is installed in a seat-type toilet is generally composed of a toilet seat that a user sits on and a main body that forms a separate body from the toilet seat provided at the rear. The main body contains functional parts such as a cleaning nozzle that cleans the human body part, a hot air dryer that performs hot air drying, and a control device for these. A toilet lid is provided on the upper surface of the toilet seat so as to cover the toilet seat. The base end of the toilet seat and the base end of the toilet lid are rotatably attached to the main body. Such a configuration is generally common.

However, according to the conventional human body local washing device described above, the toilet lid is pivotally supported by the main body so that the toilet lid and the main body are relatively close to each other and between the toilet seat and the main body. A large gap is required. For this reason, dust is likely to adhere to the gap if it gets dirty. Furthermore, when wiping off dirt with a rag or the like, there is an unfavorable point such as wiping left behind. Furthermore, in terms of design, the toilet seat and the main body are physically divided, limiting the degree of freedom in modeling.

In order to improve the above, in recent years, a hot water tank is arranged behind the toilet seat to connect the toilet seat and the main body to form an integrated toilet seat, and at the rear of the integrated toilet seat. A novel human body local washing apparatus in which a toilet lid is pivotally supported has been proposed (Patent Document 1).

In addition, according to Patent Document 2, the purpose of eliminating the complexity of disassembling and assembling at the time of production assembly and maintenance due to the fact that it is an integral toilet seat possessed by Patent Document 1 described above is Adopting a system that forms a one-piece housing by stacking the outer shell members (toilet seat base, toilet seat part, main body case) in order, and energizing with an auxiliary panel in the toilet seat opening direction and in the toilet seat closing direction Has proposed a local body washing device with a rotation damping mechanism to prevent sudden closing.

The local body cleaning apparatus according to the present invention includes an integrally constructed toilet seat in which a toilet seat portion on which a user is seated and a main body portion that houses a functional component are configured in a body. Since the toilet seat and the main body are integrally formed, the toilet seat and the main body rotate and open together. Further, it is possible to adopt a form provided with a fixing portion for holding the integrally constructed toilet seat in the toilet bowl so as to be capable of rotating and opening. In some cases, as the fixing portion, a fixing portion that has been conventionally used for rotating and opening and closing the toilet seat can be used.

The monolithic toilet seat is composed of a toilet seat where a user sits and a main body that houses functional parts. In this case, the toilet seat portion and the main body portion may be formed by integral molding, or may be mechanically joined and integrated by screws, welding, fusion, or the like. Functional parts refer to parts used in human body local cleaning equipment, such as electronic parts, electrical parts, washing parts such as washing nozzles, hot water storage parts such as tanks that store hot water, heaters that generate hot water, etc. There may be at least one of a hot water generator and a dryer that generates hot air to dry the local part of the human body. When an instantaneous hot water generation unit such as a heater that generates hot water in a short time is provided, the hot water storage unit such as a tank for storing hot water can be simplified or eliminated.

The form made into the structure to perform can be illustrated. An example of the cleaning unit is a cleaning nozzle that ejects water to a local part of the human body to clean the local part. It is preferable to have a warm water supply unit that supplies warm water that is water to be washed. As the hot water supply unit, a method having a hot water tank for storing hot water may be used, or a method having a heating unit that does not have a hot water tank and can generate hot water in a short time may be used. According to the human body local cleaning device according to the present invention, the integrally constructed toilet seat retains water present in the integrally constructed toilet seat, and suppresses the retained water from being scattered when the integrally constructed toilet seat is pivotally opened and closed. A water holding part is provided. The water holding part may be provided in the integrally constructed toilet seat, or may be provided in the fixed part. When the integrally constructed toilet seat rotates downward and is in the closed position, the water holding portion can adopt a configuration in which the water held in the water holding portion is discharged into the toilet bowl. Therefore, the water holding part has an outlet that can discharge water, and when the integrated toilet seat is in the closed position, the outlet of the water holding part is configured to face the toilet. it can. Therefore, when the toilet seat is in the closed position, the water holding part discharge port faces the toilet, so the water held in the water holding part is discharged into the toilet. For this reason, every time the integral toilet seat is closed, the water in the water holding section can be discharged into the toilet. This prevents the water held in the water holding unit from being held excessively.

FIG. 8 shows a state in which the toilet lid 21 and the integrally constructed toilet seat 22 are open (when the urine of the human body local washing apparatus 2 is used).

FIG. 9 shows a plan view of the main part of the human body local cleaning apparatus 2. As shown in FIG. 9, the toilet lid 21 is pivotally supported on the side surface of the main body 2 2 2 of the integrally constructed toilet seat 2 2. The body part 2 2 2 of the toilet seat 2 2 is composed of an electromagnetic water supply valve 2 9 2 having a water supply port 2 9 1 for supplying cleaning water, and a hot water tank 2 9 3 connected to the electromagnetic water supply valve 2 9 2 Equipped with washing nozzles 2 6 1 (washing part) connected to hot water tank 2 9 3, hot air dryer 2 7 1 for supplying hot air to the human body part after washing, electronic parts and electrical parts, etc. Built-in electrical control board 2 9 4 Between the fixed part 3 1 and the main body 2 2 2, a plurality of (two) fitting parts 2 4 0 a and 2 4 0 b are almost the same as the main body 2 2 2 of the toilet seat 2 2 Located in the center. As shown in FIG. 15, the housing of the toilet seat 2 2 is formed by assembling an upper first part 2 2 f and a lower second part 2 2 s, which are divided into two vertically. . The upper first part 2 2 f includes an upper member 2 2 1 U that is on the upper side of the toilet seat and an upper member 2 2 2 U that is on the upper side of the main body. The lower second part 2 2 s includes a lower member 2 2 1 L which is a lower side of the toilet seat and a lower member 2 2 2 L which is a lower side of the main body. The case integration means for assembling the first part 2 2 f and the second part 2 2 s to integrate the case is not particularly limited, and welding, fusion, screwing, and the like can be selected as necessary. As shown in FIG. 15, the integrally constructed toilet seat 2 2 constitutes a casing in which the toilet seat 2 2 1 and the main body 2 2 2 are connected. For this reason, the internal space of the integrally constructed toilet seat 22 is relatively large. In other words, as can be understood from FIG. 15, the casing of the toilet seat 2 2 1 constituting the front portion of the integrally constructed toilet seat 2 2 is composed of an upper member 2 2 1 U and a lower member 2 2 1 L. It is divided. The main body 2 2 2 constituting the rear part of the integrally constructed toilet seat 2 2 is divided into an upper member 2 2 2 U and a lower member 2 2 2 L.

According to this embodiment, as shown in FIG. 10, the upper member 2 2 1 U of the toilet seat 22 is provided with a heat shield plate 2 27 as a heat shield element. The heat shield 2 2 7 is provided in the boundary area between the toilet seat 2 2 1 and the body 2 2 2, It is made of a material having high heat shielding properties (for example, a resin material having a low heat transfer coefficient, a foam material having bubbles having heat shielding properties). As shown in FIG. 10, a toilet lid protrusion 2 13 d (a toilet lid first engaging portion) is formed at the rear end portion of the toilet lid 21. A locking recess 3 1 2 a (a toilet lid second engaging portion) is formed in the locking portion 3 1 2 of the fixing portion 3 1. As shown in FIG. 10, when the toilet lid 21 is turned upward, that is, in the direction of the arrow Y1, the toilet lid protrusion 2 1 3 d is the locking recess 3 1 of the fixing portion 3 1. 2 Engageably engage with a. As a result, the toilet lid 21 is maintained in the open state, that is, the standing state. The toilet lid protrusion 2 1 3 d and the locking recess 3 1 2 a can constitute a toilet lid opening maintaining means for maintaining the opened state (standing state) of the toilet lid 21.

A cleaning nozzle 26 1 (cleaning unit) for jetting warm water, which is cleaning water, is incorporated in a local part of the human body near the center of the main body 2 2 2. The cleaning nozzle 2 6 1 has a telescopic nozzle 2 6 2 that can expand and contract in the forward direction. During local cleaning, the expansion / contraction nozzle 26 2 protrudes from the nozzle opening 2 p due to water pressure, etc., and extends in the direction of the arrow K 1 toward the toilet 1. When it is not during local cleaning, the expansion / contraction nozzle 26 2 is retracted in the direction of the arrow K 2 and is hidden in the main body 2 2 2 by a return spring (not shown). A shutter 2 3 2 a as a closing member that forms part of the lower member 2 2 2 L of the toilet seat 22 2 is configured to open and close about the rotary hinge 2 3 3 a as an axis. The shutter 2 3 2 a is closed when the one-piece toilet seat 2 2 is opened (when standing, see Fig. 1 1) and opened when the one-piece toilet seat 2 2 is closed (see Fig. 1 0). The The opening / closing operation of the shutter 2 3 2 a is performed by gravity acting on the shutter 2 3 2 a. By rotating and opening the shutter 2 3 2 a, the extendable nozzle 2 6 2 can enter and exit in the directions of arrows K 1 and K 2. The shutter 2 3 2 a is held by a directly lower member 2 2 6 c disposed immediately below the cleaning nozzle 2 6 1. Behind the shutter 2 3 2 a is a shroud that functions as a water shielding wall that temporarily holds drain water from the cleaning nozzle 2 6 1, or if there is a hot water tank, drain water from the hot water tank 2 3 6 are provided. As a result, a container-like drain reservoir 2 3 5 (water holding part) having a water storage function is formed. As shown in Fig. 10, when the toilet seat 2 2 is closed, the drain puddle 2 3 5 is placed below the washing nozzle 2 6 1 that is retracted in the retracting direction (arrow K 2 direction). The drainage water falling from the cleaning nozzle 2 6 1 can be received. The shutter 2 3 2 a is also configured to receive the drain water falling from the cleaning nozzle 2 6 1.

As shown in Fig. 11, when the toilet seat 2 2 is pivoted upward (in the direction of arrow Y 1) and opened up, the drain puddle 2 3 5 is located below the tip of the washing nozzle 2 6 1 The drainage puddle 2 3 5 can receive water flowing down or dripping from the washing nozzle 2 6 1, and the drain puddle 2 3 5 outlet 2 3 5 f can be turned upward to suppress the outflow of water and Closed by shutter 2 3 2 a. As a result, the drain water temporarily held in the drain water reservoir 2 3 5 is prevented from scattering. In other words, when the toilet seat 2 2 is rotated upward to be in an upright state, the drain water is concentrated in the drain water pool 2 3 5 surrounded by the surrounding plate 2 3 6 and the direct member 2 2 6 c. The accumulated water becomes 2 3 7. For this reason, scattering of water in the toilet seat 22 is suppressed. In this way, since the drain puddle 2 3 5 receives the water falling from the cleaning nozzle 2 61, the end 2 2 6 e of the shroud 2 3 6 is close to the cleaning nozzle 2 6 1. preferable. As shown in Fig. 11, when the toilet seat 2 2 stands up (in the direction of arrow Y 1), the shutter 2 3 2 a covers the cleaning nozzle 2 6 1 from the outside to conceal it. It is possible to prevent the cleaning nozzle 2 6 1 from becoming dirty.

As shown in FIG. 10, when the toilet seat 2 2 is rotated downward (in the direction of arrow Y 2) and closed, the shutter 2 3 2 a is rotated and opened by gravity, and the drain puddle 2 3 5 and shutter 2 3 2 a lie in the horizontal or near-horizontal state. For this reason, the drain port 2 3 5 f of the drain reservoir 2 3 5 is oriented in a horizontal or nearly horizontal state. Therefore, the drain water in the drain reservoir 2 3 5 is naturally discharged into the toilet 1 by gravity from the outlet 2 3 5 f. The shutter 2 3 2 a can be expected to have a guiding action for guiding the drain water into the toilet 1. Accordingly, every time the integral toilet seat 22 is swung downward and closed, the drain water accumulated in the drain water reservoir 2 35 is naturally discharged into the toilet 1 by gravity. Therefore, accumulation of a large amount of water in the drain water pool 2 3 5 over a long period is suppressed. When the toilet seat 2 2 is rotated downward (arrow Y 2 direction) and closed, the shirt 2 3 2 a is automatically opened by gravity as shown in FIG. For this reason, the shutter 2 3 2 a does not interfere with the protrusion of the expansion / contraction nozzle 2 6 2 in the direction of the arrow K 1. available.

As shown in Fig. 12, the toilet lid 2 1 has a right side plate 2 1 1 a having a hinge hole 2 1 3 a and a left side plate 2 1 1 b having a hinge hole 2 1 3 b on both sides of the rear part. Prepare. The hinge holes 2 1 3 a and 2 1 3 b are set substantially on the same axis. One hinge hole 2 1 3 a is rotatably fitted to the pivot shaft 2 2 9 from the lower member 2 2 2 of the main body 2 2 2. The other hinge hole 2 1 3 'b is the toilet lid output shaft 2 5 6 so as to rotate together with the toilet lid output shaft 2 5 6 of the toilet lid opening / closing drive device 2 5 5 (second opening / closing drive device). Is fitted. Therefore, when the toilet lid opening / closing drive device 2 5 5 is turned on and the toilet lid output shaft 2 5 6 rotates about its axis, the toilet lid output shaft 2 5 6 and the pivot shaft 2 2 9 are centered. As a result, the toilet lid 21 is opened and closed. The toilet lid output shaft 2 5 6 and the pivot shaft 2 2 9 are along the same axis, and are the rotation center of the toilet lid 21.

When the toilet lid opening / closing drive device 2 5 5 is turned on, the toilet lid output shaft 2 5 6 rotates. When the toilet lid opening / closing drive device 2 5 5 is off, the toilet lid output shaft 2 5 6 is in a free state so that it can freely rotate with respect to the toilet lid opening / closing drive device 2 5 5. As shown in FIG. 12, the toilet lid opening / closing drive device 2 5 5 is provided with a fixed frame 2 5 7 formed on the side surface of the lower member 2 2 2 L of the main body 2 2 2 of the toilet seat 2 2 integrally formed. And fixed to the inside of the integral toilet seat 2 2 with fixing screws 2 5 4. Therefore, when the integral toilet seat 22 rotates, the toilet lid opening / closing drive device 2 55 fixed to the integral toilet seat 22 also opens in the same direction at the same angle. The toilet lid opening / closing drive device 2 5 5 can be formed of motors.

The fixed part 3 1 has a fixed base 3 1 1 fixed to the mounting part 1 1 of the toilet 1 with bolts 3 1 5 a and 3 1 5 b, and a cross section that protrudes upward on both sides of the fixed base 3 1 1 H It has a to-be-inserted portion 3 1 1 a and 3 1 1 b that form a rectangular tube shape. The inserted portions 3 1 1 a and 3 1 1 b have an inserted space 3 1 1 x in the shape of a rectangular tube space. The fixed base 3 11 1 is formed with a pair of por ridges 3 1 4 a and 3 1 4 b extending in the front-rear direction of the toilet seat 2 1 1. As shown in Fig. 4, the rubber washer 3 1 6 a is attached with the head of the toilet bowl fixing bolt 3 1 5 a, 3 1 5 b fitted into the bolt groove 3 1 4 a, 3 1 4 b. The fixing part 3 1 is detachably fixed to the mounting part 1 1 of the toilet 1.

Now, a description will be given of when the toilet seat 2 2 is detachably installed on the toilet 1. First, as shown in FIG. 14, the integrally constructed toilet seat 22 is disposed above the fixed portion 3 1. After that, the one-piece toilet seat 22 is lowered in the direction of arrow DA. As a result, the fitting part 2 40 of the integrally constructed toilet seat 2 2 0 0 a square tube shaped insertion part 2 4 1 c is removably inserted into the fixed part 3 1 in the rectangular tube shaped insertion part 3 1 1 a. Similarly, the fitting part 2 4 0 b of the one-piece toilet seat 2 2 can be attached to and detached from the square tube-shaped insertion part 2 4 1 d of the fixed part 3 1 and 3 1 1 b. Plug in. Since the rectangular tube shapes are inserted, positioning accuracy for positioning the integrally constructed toilet seat 22 is ensured. As a result, the toilet seat 22 is positioned so as to be detachably attached to the toilet 1. Therefore, the fitting portions 2 40 a and 2 4 0 b can function as positioning elements for positioning the integrated toilet seat 22 when the integrated toilet seat 22 is installed on the toilet 1. When an unlocking selection mechanism for detachably locking the integrally constructed toilet seat 22 to the fixing portion 31 is provided, it is preferable that the unlocking selection mechanism is in a locking form. According to this embodiment, as described above, the output shaft 2 5 2, the support shaft 2 5 9, etc. are predetermined by the guide rod portions 2 4 5 a, 2 4 5 b and the flange portions 2 4 4 a, 2 4 4 b. It is configured so that it can be kept in the flow state at the height position. Also, as shown in Fig.13, there is a shaft clearance 2 4 7 a between the upper surface of the output shaft 2 5 2 and the support shaft 2 5 9 and the upper end of the fixed holding portions 2 4 1 a and 2 4 1 b. , 2 4 7 b. The shaft skimmers 2 4 7 a and 2 4 7 b ensure the float displacement of the output shaft 2 52 and the support shaft 2 59.

When cleaning, etc., the toilet seat 2 2 is lifted upward (in the direction indicated by the arrow DB shown in FIG. 14) with the toilet bowls 3 1 5 a and 3 1 5 b fastened to the toilet 1. As a result, the fitting part 2 4 0a of the toilet seat 2 2 having the rectangular body shape is detached from the rectangular tube-shaped insertion part 2 4 1 c of the fixed part 3 1 and the rectangular tube-shaped insertion part 3 1 1 a. Let Similarly, the fitting portion 2 4 0 b of the integrally constructed toilet seat 2 2 is detached from the rectangular tube-shaped insertion portion 2 4 1 d of the fixed portion 3 1 and the rectangular tube-shaped insertion portion 3 1 1 b of the fixing portion 3 1. . As a result, the toilet seat 2 2 can be lifted and removed from the toilet 1 easily. In this case, when an unlocking selection mechanism for detachably locking the integrally constructed toilet seat 2 2 to the fixed portion 31 is provided, the integrally constructed toilet seat 2 is in a state in which the unlocking selection mechanism is released. Lifting 2 is preferred. Even when the toilet seat 2 2 is not removed from the toilet 1, even if the toilet seat 2 2 is lifted to a certain height in the direction of the arrow DB, it can be cleaned between the fixed part 3 1 and the toilet seat 2 2 A gap can be formed. Similarly, a cleaning gap can be formed between the toilet 1 and the one-piece toilet seat 2 2. The user can perform cleaning and the like through these gaps. If necessary, toilet 1 Toilet bowl fixing bolts 3 1 5 a and 3 1 5 b can be removed. The opening / closing drive device 2 5 1 (first opening / closing drive device) drives the integrally constructed toilet seat 22 2 for rotational opening and closing, and can be formed of motors. When the opening / closing drive device 2 5 1 is turned on, the output shaft 2 5 2 rotates. When the opening / closing drive device 2 51 is off, the output shaft 2 52 of the opening / closing drive device 2 51 is in a free state so that it can freely rotate with respect to the opening / closing drive device 2 51.

As shown in Fig. 4, the opening / closing drive unit 2 5 1 is a lower part of the integral toilet seat 2 2 2 2 1 The mounting base 2 2 8 provided on the L 2 2 8 is fixed to the holding plate 2 5 4 x 2 5 3 Is fixed inside the toilet seat 2 2. The output shaft 2 52 of the opening / closing drive device 25 1 is prevented from rotating with respect to the integral toilet seat 22 2 so as to be able to rotate integrally with the integral toilet seat 2 2. Specifically, as shown in FIG. 13, parallel chamfered D-cut flange portions 2 5 2 d (two locations) are formed on the output shaft 2 52. The D cut portion 2 5 2 d is fitted in the vertically long holding hole 2 4 1 X of the fixed holding portion 2 1 a and is prevented from rotating. Therefore, as can be understood from FIG. 13, when the opening / closing drive device 2 51 is turned on and the output shaft 2 52 rotates around its axis, the output shaft 2 52 stops at that position. In this state, that is, in a non-rotating state with respect to the toilet 1, the opening / closing drive device 2 51 rotates together with the toilet seat 2 2 having an integrated structure. When the one-piece toilet seat 2 2 pivots, the rear end 2 2 r of the one-piece toilet seat 2 2 has an output shaft 2 5 2 toward the space 2 2 k below the rear end 2 2 r. Rotate in the direction of arrow Y 5 around the axis of. The output shaft 2 5 2 and the support shaft 2 5 9 are arranged on the same axis, and the integrally constructed toilet seat 2 2 pivots around the output shaft 2 52 and the support shaft 2 5 9. However, since the fitting portion 2 4 0 b is not an output shaft, the support shaft 2 59 can be rotated with respect to the fixed holding portion 2 4 1 b.

A description will be added with reference to FIGS. FIG. 16 shows a state where the toilet lid 21 and the integrally constructed toilet seat 22 are both closed. Since the toilet seat 2 2 is closed, both the toilet lid opening / closing drive device 2 5 5 and the opening / closing drive device 2 5 1 provided inside the integrated toilet seat 2 2 are assumed to be regular mounting positions. ing. FIG. 17 shows a state in which the toilet seat 2 1 is opened by rotating upward while keeping the toilet seat 2 2 in a closed state. According to the form shown in FIG. 17, since the integrally constructed toilet seat 2 2 is closed, the toilet lid opening / closing drive device 2 5 5 and the opening / closing drive device 2 5 1 provided inside the integrally constructed toilet seat 2 2 Both are regular installations Still in position. FIG. 18 shows a state in which the toilet seat 2 2 together with the toilet lid 2 1 is rotated upward and opened. According to the form shown in FIG. 18, the opening / closing drive device 2 5 1 is driven so that the toilet seat 2 2 is rotated about 90 degrees in the direction of the arrow Y 1 and is opened. The opening / closing drive device 2 5 1 and the toilet lid opening / closing drive device 2 5 5 arranged inside the toilet seat 2 2 are rotated with the rotation of the main body 2 2 2 and changed in direction (around 90 degrees). Yes. According to the present embodiment, the output shaft 2 5 2 and the support shaft 2 5 9 that are the rotation center of the toilet seat 2 2 are the pivot shaft 2 2 9 and the toilet lid output that are the rotation center of the toilet lid 2 1. Axes 2 5 6 are set on the same axis or substantially on the same axis. Therefore, the integrally constructed toilet seat 22 and the toilet lid 21 are set so as to rotate on the same axis or substantially the same axis. This prevents excessive distortion of the toilet lid 21 even when the integrally constructed toilet seat 22 opens and closes.

As shown in FIG. 15, between the upper member 2 2 1 U constituting the toilet seat 2 2 1 and the upper member 2 2 2 U constituting the main body 2 2 2, the heat shield plate 2 2 7 is formed. As shown in Fig. 1, the heat shield 2 2 7 runs along the width direction of the toilet seat 2 2 1, and the upper member 2 2 1 of the toilet seat 2 2 1 has an electric toilet seat heater 2 h Is arranged. As shown in FIG. 10, the upper end portion 2 2 7 u of the heat shield plate 2 2 7 is in close contact with the back surface side of the upper member 2 2 1 U. Further, the lower end 2 2 7 d of the heat shield 2 2 7 engages with the rear upper surface 2 2 1 m of the lower member 2 2 1 L of the toilet seat 2 2 1. It should be noted that the heat shield plate 2 27 may be provided with a minimum number of holes or gaps necessary for passing electrical wiring or the like as necessary. As shown in Fig. 15, the lower part of the toilet seat 2 2 1 2 2 1 At the rear end of the L, the first shutter 2 3 2 a for the cleaning nozzle and the second shutter 2 3 2 b for drying hot air Can be opened and closed.

By the way, as described above, the integrally constructed toilet seat 2 2 constitutes a casing in which the toilet seat 2 2 1 and the main body 2 2 2 are continuous, and the internal space of the integrally constructed toilet seat 2 2 is relatively small. It tends to be large and continuous. For this reason, heating of the toilet seat 2 2 1 tends to transfer the heat for the toilet seat to the main body 2 2 2 through the internal space, and there is a limit to reducing the power consumption of the toilet seat heater 2 h formed by electric heating. There is. Furthermore, since a temperature rise in the main body 2 2 2 is also induced, there is room for improvement in order to increase the reliability of the functional parts accommodated in the main body 2 2 2. In this respect, according to this embodiment, as shown in FIG. 10, between the toilet seat 2 2 1 and the main body 2 2 2 of the integrally constructed toilet seat 2 2, there is a heat shield plate 2 as a heat shield element. 2 7 is provided in the shape of a partition. The heat shield 2 2 7 enhances the incompatibility between the internal space of the toilet seat 2 2 1 and the internal space of the main body 2 2 2. Specifically, the communication between the internal space of the toilet seat 2 2 1 and the internal space of the main body 2 2 2 is blocked. For this reason, when the toilet seat heater 2 h of the toilet seat 2 2 1 is heated, the heat of the heated toilet seat 2 2 1 is transmitted to the main body 2 2 2 through the internal space, etc. Suppressed by heat shield 2 2 7. Therefore, the temperature rise in the main body 2 2 2 is suppressed, and various functional parts housed in the main body 2 2 2 (for example, electronic and electric parts such as the electric control board 29 4, toilet lid opening / closing drive) Device 2 5 5, toilet seat opening and closing drive device 2 5 1, dryer 2 7 1, etc.), contributing to improved reliability, durability, and longer life.

In addition, since the heat of the toilet seat 2 2 1 as a heating toilet seat is suppressed by the heat shield 2 2 7, the temperature of the toilet seat 2 2 1 is secured. It is also advantageous in that it can contribute to energy saving and power saving, and can also contribute to the reduction of the heating capacity of the toilet seat heater 2 h. The heat shield plate 2 27 may be formed integrally with the integrally constructed toilet seat 22 or may be attached to the integrally constructed toilet seat 22 later. Further, as shown in FIG. 1, the heat shield 2 2 7 is provided between the toilet seat 2 2 1 of the integrally constructed toilet seat 2 2 and the main body 2 2 2 so as to substantially follow the contour of the user's buttocks. It is For this reason, when the user's bottom is seated on the toilet seat 2 2 1 of the one-piece toilet seat 2 2, the heat shield 2 2 7 is located near the bottom and is a heating toilet seat. It can contribute to maintaining the temperature in the area near the bottom out of 2 2 1 and is suitable for use in winter. Further, as shown in FIG. 10, an air heat insulating layer 2 2 7 a as a heat shielding element is also formed between the toilet seat 2 2 1 and the main body 2 2 2, so that the toilet seat 2 2 The transfer of the heat of 1 to the main body 2 2 2 is further suppressed. The air heat insulating layer 2 2 7 a may be formed of air, or a gel-like substance having a high heat insulating property may be disposed in the air heat insulating layer 2 2 7 a. Furthermore, according to the present embodiment, as shown in FIG. 10, the upper end 2 2 7 u of the heat shield 2 2 7 is in close contact with the back side of the upper member 2 2 1 U of the toilet seat 2 2 1. . For this reason, the air shielding property between the interior space of the toilet seat 2 2 1 and the interior space of the main body 2 2 2 is enhanced. Therefore, the entry and exit of air between the internal space of the toilet seat 2 2 1 and the internal space of the main body 2 2 2 is suppressed. Therefore, toilet seat 2 2 Convection due to air heated by the toilet seat heater 2h for heating toilet seat 1 is suppressed. As a result, it is possible to prevent heat transfer in a portion where the temperature is highest and air convection is likely to occur inside the toilet seat 2 2 1. Similarly, the lower end 2 2 7 d of the heat shield 2 2 7 is also engaged with the rear end of the lower member 2 2 1 L of the toilet seat 2 2 1 of the main body 2 2 2. In this case, the interior space of the toilet seat 2 2 1 and the interior space of the main body 2 2 2 are improved. Therefore, the entry and exit of air between the internal space of the toilet seat 2 2 1 and the internal space of the main body 2 2 2 is suppressed. As a result, the heat of the toilet seat heater 2 h can be efficiently used for heating the toilet seat portion 2 21, and the ability as a heating toilet seat can be maintained while energy saving of the toilet seat heater 2 h is achieved.

When the toilet lid 2 1 is rotated and opened in the direction of arrow Y1, the toilet lid output shaft 2 5 6 of the toilet lid opening / closing drive device 2 5 5 shown in Fig. 1 2 is rotated in the opening direction, and the toilet lid output When the shaft 2 5 6 reaches a predetermined position, the toilet lid opening / closing drive device 2 5 5 is stopped. At this time, as shown in FIG. 10, the locking recess 3 1 2 a formed on the back surface of the locking portion 3 1 2 of the fixing portion 3 1 and the toilet lid protrusion 2 1 3 d are detachably engaged. And both are combined. Thereby, the standing state of the toilet lid 21 is maintained. The toilet lid opening / closing drive device 2 5 5 for opening and closing the toilet lid 2 1 and the opening / closing drive device 2 5 1 for opening and closing the integrated toilet seat 2 2 are both fixed inside the integrated toilet seat 2 2. Yes.

When the toilet lid opening / closing drive device 2 5 5 is turned on in the opening direction from the state in which the toilet lid 2 1 shown in Fig. 6 and the toilet seat 2 2 are both closed, the integrated configuration as shown in Fig. 17 While the toilet seat 2 2 is closed, the toilet lid 2 1 can be rotated upward to be opened. Further, when the opening / closing drive device 25 1 is driven on in the opening direction, as shown in FIG. 18, the integrally constructed toilet seat 2 2 is turned upward by about 90 ° to 110 ° to be opened. It is possible to clean the back of toilet bowl 1 and board 2 or main plate 2 2 2.

As shown in FIG. 18, when the integrally constructed toilet seat 2 2 is pivoted and opened upward, the toilet lid opening / closing drive device 2 5 5 held inside the integrally constructed toilet seat 2 2 is also attached together with the toilet lid output shaft 2 5 6. At the same time, the same angle is rotated in the same direction. In this case, the toilet lid 21 in the upright position may further rotate in the direction of arrow Y3 (see Fig. 18). Therefore, when the toilet seat 22 is rotated and opened with the toilet lid 21 being pivoted upward, the toilet lid opening / closing drive device 2 55 is The toilet lid output shaft 2 5 6 fixed to the toilet lid 2 1 is configured to freely rotate with respect to the toilet lid opening / closing drive device 2 5 5. At this time, in order to prevent the toilet lid 21 from falling further in the opening direction (in the direction of arrow Y3 shown in FIG. 18) with the opening operation of the toilet seat 22 as shown in FIG. The locking recess 3 1 2 a formed on the back surface of the locking portion 3 1 2 of the fixing portion 3 1 and the toilet lid protrusion 2 1 3 d are detachably engaged. As a result, the standing state of the toilet cover 21 is maintained.

Next, when only the one-piece toilet seat 2 2 is to be rotated and closed while the toilet lid 2 1 is opened in the standing state, the opening / closing drive device 2 5 1 for opening and closing the one-piece toilet seat 2 2 is closed. By turning on in the direction, the integrally constructed toilet seat 22 is pivotally closed in the downward direction, that is, in the direction of the arrow Y2. Also in this case, if the toilet lid opening / closing drive device 2 5 5 is turned off as the toilet seat 2 2 is pivotally closed, the toilet lid opening / closing drive device 2 5 5 and the toilet lid output shaft 2 5 6 are free. Therefore, the engagement state between the locking recess 3 1 2 a formed on the back surface of the locking portion 3 1 1 and the toilet lid protrusion 2 1 3 d is continued well. Therefore, even if the opening / closing drive device 25 1 is driven in the closing direction, the one-piece toilet seat 2 2 is maintained upright. When the toilet lid 2 1 standing up is closed, the toilet lid opening / closing drive device 25 5 is turned on in the closing direction, and the toilet lid output shaft 25 6 of the integrally constructed toilet seat 22 is driven in the closing direction. As a result, the engagement between the locking recess 3 1 2 a and the toilet lid protrusion 2 1 3 d is forcibly released due to mutual elastic deformation, and the toilet lid 2 1 can be rotated and closed in the direction of arrow Y 2. it can.

By the way, the toilet 1 is made of earthenware produced industrially, and the mounting surface of the mounting portion 11 of the toilet 1 may have distortion or the like in a strict sense. This is even more so when toilet 1 goes through the sintering process. Therefore, when the body part 2 2 2 of the toilet seat 2 2 is fixed to the mounting part 1 1 of the toilet 1 rigidly (high rigidity state), the output shaft 2 5 2 and the support shaft 2 5 9 etc. The support is also likely to be rigid (high rigidity). In this case, when the user is seated on the toilet seat 2 2 1 of the integral toilet seat 2 2, when the weight of the user is loaded on the toilet seat 2 2 1 of the integral toilet seat 2 2, the mounting portion 1 1 of the toilet 1 The rubber legs 2 2 3 may not partially land on the toilet 1 due to the distortion of the mounting surface, and unnecessary stress may be applied to the integral toilet seat 2 2.

In this regard, according to this embodiment, the toilet seat 2 2 is mounted on the toilet 1 In this state, as described above, the output shaft 2 5 by the bearing portions 2 4 3 a and 2 4 3 b urged by the urging forces of the elastic bodies 2 4 6 a and 2 4 6 b which are urging members 2 and the support shaft 2 5 9 (corresponding to the rotation center axis of the body-constituting toilet seat 2) float, for example, by about 0.1 to about 1 millimeter and are in a flow trap state. As a result, the bottom 2 2 3 b of the toilet seat 2 2 is equivalent to Δt (see Fig. 12). That is, the integrally constructed toilet seat 22 is held in the toilet 1 in a flow trap state in which a minute amount can sink. Then, when the user sits on the toilet seat 2 2 1 of the integrally constructed toilet seat 2 2, the output shaft 2 5 2 and the support shaft 2 5 9 etc. are piled on the urging force of the elastic bodies 2 4 6 a and 2 4 6 b Descends when seated. As a result, the rubber legs 2 2 3 on the back surface of the toilet seat 2 2 can reliably contact the toilet 1. For this reason, it is possible to suppress a large force such as a shearing force from acting on the output shaft 2 52 and the support shaft 2 59. Furthermore, it is possible to suppress the partial load from being applied to the opening / closing drive device 2 51.

On the other hand, there is a convex part on the mounting surface of the mounting part 1 1 of the toilet 1, and even when the toilet seat 2 2 1 of the toilet seat 2 2 is about to lift, the output that is in the float state Since the shaft 2 5 2 or the support shaft 2 5 9 can move upward, it is possible to suppress a large load from being applied to the output shaft 2 5 2 or the support shaft 2 5 9 and the opening / closing drive device 2 5 1 as described above. Is done. The structure in which the toilet seat 2 2 is suspended by its own weight without providing the elastic bodies 2 4 6 a and 2 4 6 b that exert the urging force to float the bearings 2 4 3 a and 2 4 3 b However, the output shaft 2 52 or the support shaft 2 59 or the like may form a gap in which the vertical movement can be appropriately performed.

Now, according to the present embodiment, when the cleaning function of the human body local cleaning device is used, as shown in FIG. 10, the expansion / contraction nozzle 2 6 2 of the cleaning nozzle 2 6 1 expands in the direction of the arrow K 1 and expands and contracts. Wash water is ejected from nozzle 2 62 toward the local part of the human body. When the cleaning is completed, the expansion / contraction nozzle 2 62 of the cleaning nozzle 2 61 is retracted in the direction of arrow K 2 by return means such as a return panel. During cleaning, drain water may fall from the cleaning nozzle 2 6 1. Even in such a case, the drain water is concentrated in the drain reservoir 2 3 5. When the integrated toilet seat 2 2 is closed, as shown in FIG. 10, the drain water in the drain water pool 2 3 5 is separated from the first shutter 2 3 2 a in the opened state and the first shutter 2 3 2 a in the opened state. It will be discharged into toilet 1 through 2 shutter 2 3 2 b It ’s a sea urchin. When the toilet seat 2 2 is closed, the first shutter 2 3 2 a and the second shutter 2 3 2 b are automatically opened by the action of the weight (not shown) or by the gravitational action. The drain water of the reservoir 2 3 5 can be discharged into the toilet 1. When the toilet seat 2 2 is rotated and released in the direction of the arrow Y1, as shown in Fig. 11, the first shutter 2 3 2 a and the second shutter 2 3 2 b Is automatically closed by the gravitational action, and the drain water of the drain water reservoir 2 35 is prevented from being scattered in the integral toilet seat 22.

However, the drain water collected in the drain water reservoir 2 3 5 may not be drained completely due to surface tension or contamination. In such a case, even if the one-piece toilet seat 22 is stood up in an open state, residual water is prevented from splashing inside the enclosure plate 2 36. In particular, even if the toilet seat 2 2 is erected in the fully open state, the remaining water is prevented from splashing inside the enclosure plate 2 3 6. Therefore, the possibility of water adhering to functional parts such as electric parts and electronic parts inside the integrally constructed toilet seat 22 is suppressed. Therefore, it is possible to provide a highly reliable human body local washing apparatus for functional parts such as electric parts and electronic parts.
