Description

  The present invention relates to a human body local cleaning device, and more particularly to a human body local cleaning device having an integral 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 integrally configured.

  A human body local cleaning device that is installed and used in a stool type toilet is generally composed of a toilet seat that a user sits on and a main body that is provided at the rear of the toilet seat and separates from the toilet seat. The main body unit stores functional parts such as a cleaning nozzle that cleans the human body part, a hot air drying device 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 often seen.

  However, according to the above-described conventional human body local cleaning device, the toilet lid is pivotally supported by the main body so that it is relatively between the toilet lid and the main body and between the toilet seat and the main body. A large gap is required. For this reason, dirt and dust tend to adhere to this gap. Furthermore, when wiping off dirt with a rag or the like, there is an unfavorable point such as unwiping. Furthermore, in terms of design, the toilet seat and the main body are physically divided, and it is also true that the degree of freedom in modeling is limited.

  In order to improve the above, in recent years, a hot water tank is arranged behind the toilet seat to form an integrated toilet seat by integrating the toilet seat and the main body, and a toilet lid is attached to the rear of the integrated toilet seat. There has been proposed a novel human body local cleaning device that is pivotally supported (Patent Document 1).

Further, according to Patent Document 2, three outer shells are used for the purpose of eliminating the complexity of disassembling and assembling during production assembly and maintenance due to the integral toilet seat of Patent Document 1 described above. Adopts a system that forms a unitary structure by sequentially stacking members (toilet seat base, toilet seat part, main body case), urges with an auxiliary spring in the toilet seat opening direction, and closes rapidly in the toilet seat closing direction There has been proposed a human body local cleaning device having a rotation damping mechanism for preventing operation.

Accordingly, the heat shield plate 227 can be provided even in a narrow space. The heat shield plate 227 may be integrally formed with the integrally constructed toilet seat 22 or may be attached to the integrally constructed toilet seat 22 later.

  As shown in FIG. 10, a toilet lid protrusion 213 d (a toilet lid first engagement portion) is formed at the rear end portion of the toilet lid 21. A locking recess 312 a (a toilet lid second engagement portion) is formed in the locking portion 312 of the fixing portion 31. As shown in FIG. 10, when the toilet lid 21 is rotated upward, that is, in the direction of the arrow Y1, to be in the open state, the toilet lid protrusion 213d is detachably engaged with the locking recess 312a of the fixing portion 31. . Thereby, the toilet lid 21 is maintained in an open state, that is, an upright state. The toilet lid protrusion 213d and the locking recess 312a can constitute toilet lid opening maintaining means for maintaining the opened state (standing state) of the toilet lid 21.

  A cleaning nozzle 261 (cleaning unit) that ejects warm water, which is cleaning water, is incorporated in a local part of the human body near the center of the main body 222. The cleaning nozzle 261 has an expandable / contractible nozzle 262 that can be expanded and contracted forward. At the time of local cleaning, the expansion / contraction nozzle 262 protrudes from the nozzle opening 2p due to water pressure or the like and extends in the direction of the arrow K1 toward the toilet 1. When it is not during local cleaning, the expansion / contraction nozzle 262 is retracted in the direction of the arrow K2 by a return spring (not shown) and concealed in the main body 222.

  A shutter 232a that forms a part of the lower member 222L of the toilet seat 22 is configured to open and close about the rotary hinge 233a. The shutter 232a is closed when the integral toilet seat 22 is opened (when standing, see FIG. 11), and is opened when the integral toilet seat 22 is closed (see FIG. 10). The opening / closing operation of the shutter 232a is performed by gravity acting on the shutter 232a. The telescopic nozzle 262 can enter and exit in the directions of the arrows K1 and K2 by rotating and opening the shutter 232a. The shutter 232a is held by a member 226c that is directly below the cleaning nozzle 261. A shroud 236 that functions as a water shielding wall that temporarily holds drain water from the cleaning nozzle 261 or drain water from the hot water tank is provided behind the shutter 232a. As a result, a drain water pool 235 (water holding portion) is formed. As shown in FIG. 10, when the toilet seat 22 is closed, the drain water reservoir 235 is positioned below the washing nozzle 261 so that the drain water falling from the washing nozzle 261 can be received. The shutter 232a is also configured to receive the drain water falling from the cleaning nozzle 261.

  As shown in FIG. 11, when the integrally constructed toilet seat 22 is turned upward and stands up (in the direction of arrow Y1), the discharge port 235f of the drain water pool 235 is closed by the shutter 232a. This prevents the drain water temporarily held in the drain water pool 235 from scattering.

The D cut portion 252d is fitted in the vertically long holding hole 241x of the fixed holding portion 241a and is prevented from rotating.

  Therefore, as can be understood from FIG. 13, when the toilet seat opening / closing drive device 251 is turned on and the output shaft 252 rotates about its axis, the output shaft 252 is stationary at that position, that is, the toilet bowl. 1, the toilet seat opening / closing drive device 251 rotates together with the integrally constructed toilet seat 22. When the integrally constructed toilet seat 22 is pivotally opened and closed, as can be understood from FIG. 13, the rear end portion 22r of the integrally constructed toilet seat 22 faces the space 22k below the rear end portion 22r. Rotate around in the direction of arrow Y5. The output shaft 252 and the support shaft 259 are disposed on the same axis, and the integrally constructed toilet seat 22 is opened and closed around the output shaft 252 and the support shaft 259. However, since the fitting portion 240b is not an output shaft, the support shaft 259 is rotatable with respect to the fixed holding portion 241b.

  A description will be added to FIGS. FIG. 16 shows a state where the toilet lid 21 and the integrally constructed toilet seat 22 are both closed. Since the integrated toilet seat 22 is closed, both the toilet lid opening / closing drive device 255 and the toilet seat opening / closing drive device 251 provided inside the integrated toilet seat 22 are in the proper mounting positions. FIG. 17 shows a state in which the toilet lid 21 is pivoted upward and opened while maintaining the integrally constructed toilet seat 22 in a closed state. According to the form shown in FIG. 17, since the integrated toilet seat 22 is closed, both the toilet lid opening / closing drive device 255 and the toilet seat opening / closing drive device 251 provided in the integrated toilet seat 22 are in the normal mounting position. It remains. FIG. 18 shows a state where the toilet seat 22 together with the toilet lid 21 is pivoted upward and opened. According to the embodiment shown in FIG. 18, the toilet seat opening / closing drive device 251 is driven to rotate the integrated toilet seat 22 by about 90 degrees so that the toilet seat is opened and closed. The directions of the driving device 251 and the toilet lid opening / closing driving device 255 are changed (about 90 degrees) by rotating with the rotation of the main body 222.

  According to this embodiment, the output shaft 252 and the support shaft 259 that are the rotation center of the toilet seat 22 are the same as the pivot shaft 229 and the toilet lid output shaft 256 that are the rotation center of the toilet lid 21. Alternatively, they are set substantially on the same axis. Therefore, both the toilet seat 22 and the toilet lid 21 are set so as to rotate on the same axis or substantially around the same axis. For this reason, it is possible to reduce the size of the swivel space required for opening and closing. Further, even when the integrally constructed toilet seat 22 is pivotally opened and closed, excessive distortion of the toilet lid 21 is prevented.

  As shown in FIG. 15, a heat shield plate 227 is formed between the upper member 221 </ b> U constituting the toilet seat 221 and the upper member 222 </ b> U constituting the main body 222. As shown in FIG. 1, the heat shield plate 227 is along the width direction of the toilet seat 221, and an electric toilet seat heater 2 h is disposed on the upper member 221 </ b> U of the toilet seat 221. As shown in FIG. 10, the upper end portion 227u of the heat shield plate 227 is in close contact with the back surface side of the upper member 221U. Further, the lower end portion 227d of the heat shield plate 227 engages with the rear end upper surface portion 221m of the lower member 221L of the toilet seat portion 221. Note that the heat shield plate 227 may be formed with a minimum number of holes or gaps necessary for passing electrical wiring or the like as necessary.

  By the way, as described above, the integrally constructed toilet seat 22 constitutes a casing made of a resin base material in which the toilet seat portion 221 having the first internal space 221v and the main body portion 222 having the second internal space 222v are continuous. The interior space 22v of the integrally constructed toilet seat 22 occupies a relatively large continuous volume. For this reason, there is a tendency that heat for the heating toilet seat of the toilet seat portion 221 moves to the main body portion 222 through the internal space, a heat transfer loss is considered, and there is a limit in reducing power consumption of the toilet seat heater 2h. Furthermore, since a temperature rise in the main body 222 is also induced, there is room for improvement in order to increase the reliability of the functional components accommodated in the main body 222.

  In this regard, according to the present embodiment, as shown in FIG. 10, a heat shield element is provided between the first internal space 221 v of the toilet seat portion 221 of the integrally constructed toilet seat 22 and the second internal space 222 v of the main body portion 222. The heat shield plate 227 is provided in a partition shape. As a result, the incompatibility between the first internal space 221v of the toilet seat portion 221 and the second internal space 222v of the main body portion 222 is enhanced. Specifically, the communication between the first internal space 221v of the toilet seat 221 and the second internal space 222v of the main body 222 is blocked or substantially blocked. For this reason, when the toilet seat heater 2h functioning as a heating unit is in a heating operation, the heat shield plate 227 suppresses the heat of the warmed toilet seat portion 221 from being transmitted to the second internal space 222v of the main body portion 222. The Accordingly, the temperature rise in the second internal space 222v of the main body 222 is suppressed, and various functional components (for example, electronic components such as the electric control board 294 and electric components accommodated in the second internal space 222v of the main body 222). , Toilet lid opening / closing drive device 255, toilet seat opening / closing drive device 251, drying device 271, etc.) can contribute to improving the reliability, durability, and extending the service life.

  Since the heat of the toilet seat 221 is suppressed by the heat shield plate 227 as described above, it is advantageous to ensure the temperature of the toilet seat 221 that functions as a heating toilet seat, Contributes to energy saving and power saving. Furthermore, it can contribute to miniaturization of the heating capacity of the toilet seat heater 2h.

  Further, as shown in FIG. 1, the heat shield plate 227 is provided between the toilet seat 221 and the main body 222 of the integrally constructed toilet seat 22 so as to substantially follow the contour of the user's hip. For this reason, when the user's bottom is seated on the toilet seat 221 of the integrally constructed toilet seat 22, the heat shield 227 is positioned outside the vicinity of the bottom, and the bottom of the toilet seat 221 that functions as a heating toilet seat. This contributes to maintaining the temperature in the area near the head at an appropriate temperature, and is suitable for use in winter. In addition, since the heat shield plate 227 having a reinforcing function is positioned near the buttocks of the seated user, it is possible to enhance the reinforcement of the seated buttocks against the load.

  Further, as shown in FIG. 10, an air heat insulating layer 227 a as another heat shielding element is also formed between the toilet seat 221 and the main body 222, so that the heat of the toilet seat 221 is transmitted to the main body 222. This is further suppressed. That is, a double heat insulating structure of the air heat insulating layer 227a and the heat insulating plate 227 is employed. The air heat insulating layer 227a is not only formed of air, but a gel-like substance having high heat shielding properties may be disposed on the air heat insulating layer 227a.

  Furthermore, according to the present embodiment, as shown in FIG. 10, the upper end portion 227u of the heat shield plate 227 is in close contact with the back surface side of the upper member 221U of the toilet seat 221. For this reason, the communication blocking property between the first internal space 221v of the toilet seat portion 221 and the second internal space 222v of the main body portion 222 is enhanced. Therefore, it is advantageous for suppressing air in and out between the first internal space 221v of the toilet seat 221 and the second internal space 222v of the main body 222. For this reason, the convection by the air heated by the toilet seat heater 2h for the heating toilet seat of the toilet seat part 221 is suppressed. Thereby, the heat transfer of the location where temperature is the highest inside the toilet seat part 221 and air convection is easy to occur can be prevented.

  Similarly, the lower end portion 227d of the heat shield plate 227 is also in close contact with the rear end portion of the lower member 221L of the toilet seat portion 221 of the main body portion 222. In this sense, the communication blocking performance is further enhanced. Yes. Therefore, the entry and exit of air between the first internal space 221v of the toilet seat portion 221 and the second internal space 222v of the main body portion 222 is suppressed. Thereby, the heat of the toilet seat heater 2h can be efficiently used for heating the toilet seat portion 221, and the ability as a heating toilet seat can be maintained while energy saving of the toilet seat heater 2h is achieved. Furthermore, the upper end portion 227u of the heat shield plate 227 is in close contact with the back surface side of the upper member 221U of the toilet seat portion 221, and the lower end portion 227d of the heat shield plate 227 is also disposed behind the lower member 221L of the toilet seat portion 221 of the main body portion 222. Since the end portion is in close contact with the end portion, the heat shield plate 227 also performs a reinforcing function. This is advantageous for strengthening the boundary region between the toilet seat 221 and the main body 222.

  By the way, when the toilet lid 21 is rotated and opened in the arrow Y1 direction, the toilet lid output shaft 256 of the toilet lid opening / closing drive device 255 shown in FIG. 12 is rotated in the opening direction, and the toilet lid output shaft 256 is moved to a predetermined position. When this happens, the toilet lid opening / closing drive device 255 is stopped. At this time, as shown in FIG. 10, the locking recess 312a formed on the back surface of the locking portion 312 of the fixing portion 31 and the toilet lid protrusion 213d are detachably engaged, and both are coupled. Thereby, the standing state of the toilet lid 21 is maintained. The toilet lid opening / closing drive device 255 for opening / closing the toilet lid 21 and the toilet seat opening / closing drive device 251 for opening / closing the toilet seat 22 are both fixed inside the toilet seat 22.

  When the toilet lid opening / closing drive device 255 is turned on in the opening direction from the state where both the toilet lid 21 and the integrally constructed toilet seat 22 shown in FIG. 16 are closed, the toilet lid 21 is rotated upward as shown in FIG. Can be opened. Further, by turning on the toilet seat opening / closing drive device 251 in the opening direction, as shown in FIG. 18, the toilet seat 22 is rotated upward by about 90 to 110 degrees to be in the open state, and the toilet 1 and / or the main body is opened. The back surface of the portion 222 can be cleaned. When closing the standing toilet lid 21, the toilet lid opening / closing drive device 255 is turned on in the closing direction, and the toilet lid output shaft 256 of the toilet seat 22 is driven in the closing direction. As a result, the engagement between the locking recess 312a and the toilet lid protrusion 213d is forcibly released by mutual elastic deformation, and the toilet lid 21 can be pivotally closed in the arrow Y2 direction.

  By the way, the toilet bowl 1 is made of earthenware produced industrially, and the mounting surface of the mounting portion 11 of the toilet bowl 1 may have distortion or the like in a strict sense. This is even more so when the toilet bowl 1 undergoes a sintering process. Accordingly, when the main body 222 of the toilet seat 22 is fixed to the mounting portion 11 of the toilet 1 in a rigid (high rigidity state), the support of the output shaft 252 and the support shaft 259 is also rigid (in a high rigidity state). easy. In this case, when the user is seated on the toilet seat part 221 of the integral toilet seat 22, when the weight of the user is loaded on the toilet seat part 221 of the integral toilet seat 22, such as distortion of the attachment surface of the attachment part 11 of the toilet 1. Due to the influence, the rubber legs 223 do not partially land on the toilet 1 and there is a possibility that unnecessary stress acts on the integrally constructed toilet seat 22. In this regard, according to this embodiment, in the state where the integrally constructed toilet seat 22 is mounted on the toilet 1, as described above, the bearing portion 243a that is biased by the biasing force of the elastic bodies 246a and 246b that are biasing members. , 243b, the output shaft 252 and the support shaft 259 (corresponding to the rotation center shaft of the integral toilet seat 2) are floated, for example, by about 0.1 to 7 millimeters. As a result, the bottom 223b of the unitary toilet seat 22 floats upward from the toilet 1 equivalent to Δt (see FIG. 12). That is, the integrally constructed toilet seat 22 is held in the toilet 1 in a float state in which a minute amount can sink. When the user is seated on the toilet seat portion 221 of the integrally constructed toilet seat 22, the output shaft 252 and the support shaft 259 are lowered with the seat against the urging force of the elastic bodies 246a and 246b. Thereby, the rubber leg 223 on the back surface of the integrally constructed toilet seat 22 can reliably contact the toilet 1. For this reason, it is suppressed that stress, such as a big shearing force, acts on the output shaft 252 and the support shaft 259 or the like. In addition, it is possible to suppress the partial load from being applied to the toilet seat opening / closing drive device 251.

  On the other hand, even when a convex portion is present on the mounting surface of the mounting portion 11 of the toilet 1 and the toilet seat portion 221 of the integrally constructed toilet seat 22 is to be lifted, the output shaft 252 or the support that is in the float state is supported. Since the shaft 259 can move upward, a large load is suppressed from being applied to the output shaft 252 or the support shaft 259 or the toilet seat opening / closing drive device 251 as described above. Note that the output shaft 252 or the support shaft 259 or the like has a structure in which the integral toilet seat 22 is suspended by its own weight without providing the elastic bodies 246a and 246b that exert the urging force that floats the bearing portions 243a and 243b. Any device that forms a gap that can be moved up and down appropriately is acceptable.

  According to this embodiment, when the cleaning function of the human body local cleaning device is used, as shown in FIG. 10, the expansion / contraction nozzle 262 of the cleaning nozzle 261 extends in the direction of the arrow K1, and the cleaning water flows from the expansion / contraction nozzle 262 to the human body. It is ejected toward the local area. When the cleaning is completed, the expansion / contraction nozzle 262 of the cleaning nozzle 261 is retracted in the arrow K2 direction by return means such as a return spring. During the cleaning, drain water may fall from the cleaning nozzle 261. Even in such a case, the drain water is concentrated in the drain water pool 235. When the integrated toilet seat 22 is closed, as shown in FIG. 10, the drain water in the drain water reservoir 235 passes through the first shutter 232a in the opened state and the second shutter 232b in the opened state. It is supposed to be discharged. When the integrated toilet seat 22 is closed, the first shutter 232a and the second shutter 232b are automatically opened by a moment action of a weight (not shown) or a gravitational action, and the drain water in the drain pool 235 is taken into the toilet 1 Can be discharged. When the integrally constructed toilet seat 22 is pivotally opened in the direction of the arrow Y1, as shown in FIG. 11, the first shutter 232a and the second shutter 232b are automatically closed by the moment action or gravity action of a weight (not shown). It is suppressed that the drain water of the water pool 235 scatters in the integral toilet seat 22.

  However, the drain water collected in the drain water reservoir 235 may remain completely drained due to surface tension and dirt adhesion. In such a case, even if the integrally constructed toilet seat 22 is erected in an open state, residual water is not scattered inside the enclosure plate 236. In particular, even if the unitary toilet seat 22 is erected in the maximum open state, residual water is prevented from splashing inside the enclosure plate 236. 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 cleaning device for functional parts such as electric parts and electronic parts.

Also in the present embodiment, although not shown, a heat shield plate 227 as a heat shield element is provided between the toilet seat portion 221 and the main body portion 222 of the integrally constructed toilet seat 22. For this reason, when the toilet seat heater 2h of the toilet seat portion 221 is heated, the heat shield plate 227 suppresses the heat of the heated toilet seat portion 221 from being transmitted to the main body portion 222 through the internal space or the like. . Accordingly, the temperature rise in the main body 222 is suppressed, and various functional components (for example, electronic components and electric components such as the electric control board 294, the toilet lid opening / closing driving device 255, the toilet seat opening / closing driving device) accommodated in the main body 222. 251, drying device 271, etc.) can contribute to improving the reliability, improving the durability, and extending the service life.

Slide guide portions 319 a and 319 b are formed on both the left and right sides of the fixed base 311 of the fixed portion 31. The slide guide portions 319a and 319b extend in parallel or substantially in parallel along the front-rear direction (the directions of arrows X1 and X2 shown in FIG. 1) of the integrally constructed toilet seat 22. These slide guide portions 319a and 319b can be moved by operating a locking / demounting mechanism (not shown). The fitting portion 240 a formed on the integrally constructed toilet seat 22 has a slide portion 401. The fitting portion 240 b has a slide portion 402. The slide portions 401 and 402 are extended along the front-rear direction of the integrally constructed toilet seat 22 (the directions of arrows X1 and X2 shown in FIG. 1). When the integrated toilet seat 22 is attached to the fixed portion 31, the integrated toilet seat 22 is moved in the horizontal direction toward the rear (in the direction of the arrow X2) while the integrated toilet seat 22 is positioned in front of the toilet bowl 1. At this time, the integrated toilet seat 22 is pushed backward (in the direction of the arrow X2) to slide the slide portions 401 and 402 of the integrated toilet seat 22 along the slide guide portions 319a and 319b of the fixed base 311. It is preferable to provide an unlocking selection mechanism for detachably engaging the slide portions 401 and 402 of the integrated toilet seat 22 with the fixed base 311 when the integrated toilet seat 22 is slid to a certain position.

  When the integrated toilet seat 22 is moved or removed from the toilet 1 during cleaning or the like, the integrated toilet seat 22 is moved in the horizontal direction in the reverse direction, that is, forward (in the direction of the arrow X1). In this way, in addition to the toilet bowl 1, the back surface of the integrally constructed toilet seat 22 can be easily cleaned.
