Description

  The present invention relates to a toilet apparatus having a toilet lid that can be freely opened and closed, and more particularly to a technique for suppressing shaking when the toilet lid is opened.

  A toilet device is usually installed on the toilet bowl. This toilet device mainly comprises a casing installed on the rear upper surface of the toilet bowl, a toilet seat rotatably connected to the casing, and a toilet lid that is also rotatably connected to the casing and opens and closes the toilet seat. To do. The toilet lid is pivotally connected to the casing via the hinge portion by the hinge portions formed on the left and right sides of the base end portion of the toilet lid being fitted to support shafts protruding from the casing on the left and right sides. It has come to be. The toilet lid stops the opening operation at a predetermined open position (hereinafter referred to as a “fully opened position”). In order to stop the toilet lid reliably at the fully opened position, the toilet lid projects from the proximal end portion of the toilet lid. A structure is used in which a contact portion provided and a stopper formed on the casing are brought into contact with each other at a fully open position (see Patent Document 1).

  The above-described stopper stops the opening of the toilet lid as a structure in which the contact portion protruding from the base end portion of the toilet lid and the stopper formed on the casing side are brought into contact with each other at the fully open position. However, there is a problem that when the toilet lid is opened, the stopper is visible to the user and the appearance is poor. Further, since the stopper is formed on the hinge portion on the casing side, it is difficult to clean.

  Another prior art will be described with reference to FIG. As shown in FIG. 5, there is a toilet device in which the stopper 410 formed on the hinge portion 330 on the casing 400 side is formed on the back surface portion 420 of the casing 400 in order to improve the above-described design and cleaning properties. It was. In order to stop the opening of the toilet lid 300 of the toilet device, the rear edge portion 310 of the toilet lid 300 and the stopper 410 are brought into contact with each other. The stopper 410 has a structure protruding from the back surface portion 420 and is a rectangular parallelepiped. The rear edge portion 310 of the toilet lid 300 and the upper surface of the rectangular parallelepiped serving as the stopper 410 are in contact with each other, and the opening operation is stopped at the fully opened position. (See FIGS. 5 (a) and 5 (b))

  By providing the stopper 410 on the back surface portion 420, it is difficult for the user to visually recognize the stopper 410, so that the design is improved. Further, the stopper 410 can be easily cleaned only by wiping the back surface portion 420.

  However, in the toilet apparatus in which the stopper 410 is provided on the back surface portion 420 of the casing 400, when the toilet lid is opened with great force, a large vibration or impact is generated when the toilet lid 300 is stopped. There is. That is, the toilet lid 300 that has been opened with force by hand or electric force has the rear edge 310 of the toilet lid 300 collide with the upper surface of the stopper 410 formed on the back surface 420 of the casing 400, In the event of a collision, the trailing edge 310 directly receives the repulsive force from the stopper 410 and rebounds greatly to generate vibrations in the entire toilet lid 300. The quality of the opening / closing operation of the toilet lid 300 is greatly reduced by the vibration. In addition, due to the impact on the casing 400, there is a problem that the toilet seat supported by the shaft is lifted up slightly and hits the toilet, so that abnormal noise is generated.

  Another problem is that an external force is applied when the back surface of the toilet lid 300 is wiped during cleaning, and the rear edge 310 of the toilet lid 300 that has been in contact is deformed to the inner side of the stopper 410 due to elastic deformation and falls off the stopper 410. As a result, an abnormal noise is generated, causing the user to associate with a malfunction, or causing discomfort or anxiety.

  Although the structure which lengthens the stopper 410 back can be considered with respect to the said problem, when the depth becomes long, the stopper 410 may be visible from a user and designability is impaired. In addition, since an excessive external force is received by the stopper 410, the force cannot be released and the toilet lid 300 is detached from the hinge portion 330.

JP 2006-167307 A

  This invention is invented in view of the said problem, Comprising: When stopping a toilet lid in a full open position, it makes it a subject to provide the toilet device by which the vibration was suppressed reliably. is there.

In order to solve the above problems, a toilet device according to the present invention is in contact with a casing provided on the upper surface of a toilet bowl, a toilet lid pivotally supported by the casing, and a rear edge portion of the toilet lid. A stopper that stops the toilet lid at an open position, and the stopper protrudes from the back surface portion of the casing and is inclined downward toward the top surface of the stopper in a direction away from the back surface portion. have a sloped portion and the trailing edge portion on the inclined portion of the stopper comes into contact, it said trailing edge portion along the inclined portion slides the inclined portion elastically deformed.

  According to the invention thus configured, the toilet lid during the opening operation has the rear edge portion that reaches the fully open position along the inclined portion, and the rear edge portion and the stopper are caused by friction between the rear edge portion and the inclined portion. The momentum of the collision can be weakened. Therefore, even when the toilet lid is opened with vigor, the occurrence of shaking or vibration of the toilet lid is reliably suppressed when the toilet lid stops at the fully open position. Even if the toilet lid in the fully open position receives an external force, it slides backward along the inclination, so that a sudden change of dropping off from the stopper does not occur. Further, since the rear edge portion is elastically deformed rearward, the left and right ends tend to be deformed inward, so that deformation of the hinge portion in the opening direction can be suppressed.

  In this invention, Preferably, the said inclination part is curving so that it may become convex upward.

  According to the invention configured in this manner, the trailing edge portion slides into contact with the curved inclined portion and stops at a predetermined fully open position, so that the momentum of collision between the trailing edge portion and the stopper can be weakened. .

  According to the aspect of the present invention, there is an effect that it is possible to provide a toilet apparatus in which vibration is reliably suppressed when the toilet lid is stopped at the fully open position.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably. 1 and 2 are schematic perspective views illustrating a toilet device 100 according to an embodiment of the invention. A toilet apparatus 100 shown in FIG. 1 is provided on a western-style seat toilet 10. The toilet device 100 includes a casing 400, a toilet seat 200, and a toilet lid 300. The toilet seat 200 and the toilet lid 300 have a body washing function unit and the like that realizes washing of a user sitting on the toilet seat 200 such as a “butt”. Further, for example, the casing 400 is provided with a seating detection sensor that detects that the user is sitting on the toilet seat 200. When the seating detection sensor detects a user sitting on the toilet seat 200, when the user operates an operation unit (not shown) such as a remote controller, the cleaning nozzle can be advanced into the bowl 801 of the toilet 800. Then, the cleaning nozzle can clean the “butt” of the user sitting on the toilet seat 200 by jetting water from the water outlet provided at the tip thereof. In the present invention, the body washing function unit is not always necessary. The present embodiment is a sanitary toilet that stores cleaning water in the tank 20 and cleans the toilet 10, but may not be stored in the tank 20 but may be a direct water pressure sanitary toilet.

  FIG. 1 shows a state in which both the toilet seat 200 and the toilet lid 300 are closed. As shown in FIG. 1, the toilet lid 300 can cover the toilet seat 200 in a closed state. FIG. 2 shows a state where the toilet seat 200 is closed and the toilet lid 300 is opened. In the present specification, the front end side of the toilet lid 300 of the toilet apparatus 100 is the front side, and the side on which the toilet lid 300 is pivotally supported is the rear side, as viewed from the user standing in front of the toilet apparatus 100, It demonstrates as upper and lower along a perpendicular direction.

The toilet lid 300 includes a rear edge portion 310, a top surface portion 320, and a hinge portion 330.
The rear edge 310 is a rear edge extending in the left-right direction of the toilet lid 300.
The top surface 320 covers the seating surface of the toilet seat 200 so that it can be opened and closed. That is, the top surface portion 320 is a portion that covers the toilet seat 200 when the toilet lid 300 is closed (see FIG. 1). The toilet lid 300 covers at least a part of the casing 400.
The hinge portion 330 is a portion that is pivotally supported by a support shaft (not shown) protruding from the casing 400 and serves as a fulcrum for opening and closing the toilet lid 300. The hinge part 330 may be coupled to, fitted to, or connected to the casing 400 via an automatic opening / closing unit or a gentle closing unit that electrically opens and closes the toilet lid 300 by a motor.

  Next, a specific example of the structure of the toilet lid 300 and the stopper 410 will be described. The plan view shown in FIG. 3 is a view of the embodiment as viewed from directly above. The back surface portion 420 of the casing 400 is a rear portion from the shaft of the hinge portion 330 of the toilet lid 300 that is pivotally supported by the casing 400. Specifically, it is a substantially vertical standing wall so as to face the tank 20 at the rear of the casing 400. The stopper 410 is formed so as to protrude from the back surface portion 420 and has a semi-elliptical shape when viewed from the top surface of the casing 400. The stopper 410 of the present embodiment is not limited to this, and may be a rectangular shape or a semicircular shape when viewed from above. In this embodiment, one stopper 410 is formed at the center in the left-right direction of the back surface portion 420. However, for example, a plurality of stoppers 410 may be provided to support the toilet lid 300 at multiple points. Moreover, it is good also as a structure which forms the left-right width whole region of the back part 420 as the stopper 410, and supports the rear edge part 310 by a surface instead of a point.

  FIG. 4A is a side view of the casing 400 and the toilet lid 300 in a state where the toilet lid 300 of the present embodiment is closed. The stopper 410 protrudes from the back surface portion 420 and is integrally formed with the casing 400. The inclined portion 411 on the upper surface of the stopper 410 of this embodiment is inclined downward from the back surface portion 420 toward the rear. Specifically, the abutting surface of the toilet lid 300 is smoothly rounded and has an arc shape so as to be convex upward. The stopper 410 is not limited to this, and the side surface may be D-shaped or triangular.

  FIG. 4B is a side view of the casing 400 and the toilet lid 300 in a state where the toilet lid 300 of the present embodiment is opened. As shown in FIG. 4B, the toilet lid 300 in the opened state stops at a position where the rear edge 310 of the toilet lid 300 abuts on the upper surface of the stopper 410 and does not move further rearward due to its own weight (fully opened position). .

  The movement of the toilet lid 300 until the toilet lid 300 stops at the fully open position will be described. In the present embodiment, in the process of opening the toilet lid 300, the rear edge 310 first contacts the upper portion of the stopper 410 at a position immediately before the rear edge 310 is in contact with the stopper 410. To do. The trailing edge portion 310 descends the slope of the stopper 410 while being bent, and slides on the inclined portion 411 while gradually reducing the momentum of the opening operation by friction. Thereafter, the trailing edge portion 310 that slides at the inclined portion 411 stops at the fully open position. As a result, even when the toilet lid 300 is opened vigorously, it is possible to suppress the occurrence of vibrations and shocks when stopped at the fully open position.

  In this embodiment, since the stopper 410 is semi-elliptical in plan view as shown in FIG. 3, the contact with the rear edge 310 is a line contact. Therefore, the sliding resistance due to the contact between the two is small, and the user who wants to manually close the toilet lid 300 from the open position does not make the closing operation troublesome. Further, when the toilet lid 300 is configured to be opened and closed with a motor, it is not necessary to select a high-output motor and the cost can be reduced. Further, there is no problem that the durability of the motor is lowered.

  When an external force during cleaning is applied to the toilet lid 300 that is stopped at the fully open position, the trailing edge 310 is deformed along the curved surface of the stopper 410, so that it gently deforms. For this reason, even if the trailing edge portion 310 is dropped from the stopper 410, no abrupt change occurs, so that it is possible to suppress abnormal noise and uncomfortable feeling at the time of dropping.

  The toilet lid 100 and the casing 400 are formed of a synthetic resin, such as PP (polypropylene), and the toilet device 100 is made of a rubber resin rich in elasticity. The impact is absorbed by the elasticity of. As a result, even when the toilet lid 300 is opened vigorously, it is possible to suppress the occurrence of vibrations and shocks when stopped at the fully open position.
