Description

The disclosed embodiment relates to a toilet lid device.

Conventionally, a toilet cover device is known that has a toilet seat and a toilet cover that are rotatably attached to a casing.

Patent Document 1 discloses a toilet lid device in which the side of the toilet lid and the side of the casing are flush with each other when the toilet lid is closed. This configuration can improve the design of the toilet lid device when it is closed.

The toilet lid device described in Patent Document 1 has a gap between the bottom end of the toilet lid and the top surface of the casing so that the toilet lid does not come into contact with the casing when closed.

JP 2018-27174 A

However, for example from the perspective of design, the above-mentioned gap may be made relatively small. In such cases, for example when the toilet lid is closed forcefully or a load is applied from above, such as when a person stands on the toilet lid, the toilet lid may come into contact with the casing and the casing may be damaged.

One aspect of the embodiment has been made in consideration of the above, and aims to provide a toilet lid device that can prevent the casing from being damaged by contact with the toilet lid.

The toilet lid device according to one embodiment comprises a casing, a toilet seat and a toilet lid supported rotatably on the casing, the toilet lid comprising a top plate portion that covers the upper surfaces of the casing and the toilet seat when the toilet lid is closed, and a side plate portion that is provided on the edge of the top plate portion and covers the side surface of the toilet seat when the toilet lid is closed, and whose lower end is located above the upper surface of the casing, and further comprises a cover portion provided on at least the surface of the upper surface of the casing that faces the lower end of the side plate portion.

With this configuration, even if the toilet lid is forcefully closed or a load is applied from above, such as when a person stands on the toilet lid, the lower end of the side plate portion comes into contact with the cover portion rather than the casing. This makes it possible to prevent damage to the casing.

In addition, in the above toilet lid device, the cover part is detachable from the casing. With this configuration, if the cover part is damaged, only the cover part can be replaced.

In addition, in the toilet lid device, the casing has a support part that rotatably supports the toilet lid, and the cover part further covers the side surface of the casing forward of the support part.

When a load is applied from above to the toilet lid and the side plate portion of the toilet lid comes into contact with the cover portion, it may bend (deform) and come into contact with the side of the casing. The bending of the side plate portion at this time increases the further it is from the support portion that serves as the fulcrum for the toilet lid. In the toilet lid device according to the embodiment, by covering not only the top surface of the casing but also the side of the casing that is located forward of the support portion with the cover portion, damage to the casing can be further suppressed.

In addition, in the above-mentioned toilet lid device, the casing is installed on the upper surface of the toilet body whose side faces slope inwardly downward, and the side faces of the casing are located above the side faces of the toilet body and slope outwardly from the bottom end upward.

In this way, by slanting the side of the casing outward from the bottom end upward, the area of the top surface of the casing can be made larger. This ensures that the bottom end of the side plate of the toilet lid comes into contact with the cover portion provided on the top surface of the casing when the toilet lid is closed, while preventing the toilet lid device from becoming larger overall. In addition, by slanting the side of the casing in the same direction as the side of the toilet body, the design can be improved.

According to one aspect of the embodiment, it is possible to prevent the casing from being damaged by contact with the toilet lid.

The following describes in detail the embodiments of the toilet lid device disclosed in this application with reference to the attached drawings. Note that the present invention is not limited to the embodiments described below.

<Overall configuration of the toilet device>
First, the configuration of the toilet device according to the embodiment will be described with reference to Fig. 1 and Fig. 1 to Fig. 5. Fig. 1 is a perspective view of the toilet device according to the embodiment. Fig. 2 is a front view of the toilet device according to the embodiment, and Fig. 3 is a rear view of the toilet device according to the embodiment. Fig. 4 is a plan view of the toilet lid device according to the embodiment, Fig. 5 is a plan view of the toilet lid device according to the embodiment excluding the toilet lid, and Fig. 6 is a plan view of the toilet lid device according to the embodiment excluding the toilet seat and toilet lid.

For ease of understanding, FIG. 1 illustrates a three-dimensional Cartesian coordinate system including a Z-axis with the positive direction being the vertical upward direction. This Cartesian coordinate system may also be illustrated in other figures. This Cartesian coordinate system defines the negative view of the X-axis as the front of the toilet device, and the negative view of the Z-axis as the plane of the tray device (also called the "top surface"). For this reason, in the following explanation, the X-axis direction may be referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction (or height direction).

As shown in FIG. 1, the toilet device 1 according to the embodiment includes a ceramic toilet bowl body 2 and a toilet lid device 3.

The toilet body 2 comprises, for example, a bowl section for receiving waste, a water conduit formed at the rear (upstream) of the bowl section, and a trap pipe line that communicates with the lower part of the bowl section. A rim is formed on the upper edge of the bowl section, and a rim spout is formed on the rear side of this rim to spout flushing water supplied from the water conduit. The flushing water spouted from the rim spout descends while swirling to clean the bowl section.

As shown in Figures 2 and 3, the side surface 2b of the toilet body 2 is inclined downward and inward. This point will be described later.

The toilet lid device 3 comprises a casing 10, a toilet seat 20 (see Figure 5) on which a user sits, a toilet lid 30, and a cover part 40.

The casing 10 is installed on the top surface of the toilet body 2. The casing 10 is also installed behind the bowl of the toilet body 2. Inside the casing 10, a body washing function unit that washes the body parts (such as the buttocks) of the user sitting on the toilet seat 20 is built in. For example, inside the casing 10, a washing nozzle and a control circuit that controls the operation of the washing nozzle are provided. When the user sits on the toilet seat 20, the washing nozzle advances forward from inside the casing 10 and ejects washing water toward the user's body parts. In addition, the casing 10 may be appropriately provided with various mechanisms such as a "warm air drying function" that blows warm air toward the "buttocks" of the user sitting on the toilet seat 20 to dry them, a "deodorizing unit", and an "indoor heating unit".

As shown in Figures 5 and 6, the casing 10 has a first portion 10a that is installed on the upper surface of the toilet body 2, and a second portion 10b that rises upward from the upper surface of the first portion 10a. A pair of left and right first mounting portions 11, 11 for mounting the toilet seat 20 to the casing 10 are provided on the second portion 10b. The first mounting portions 11, 11 are, for example, insertion holes through which a pair of left and right rotating shafts (not shown) provided on the toilet seat 20 are inserted. This allows the toilet seat 20 to be rotatably supported relative to the casing 10. The first mounting portions 11, 11 may be rotating shafts. In this case, it is sufficient that the toilet seat 20 has a pair of left and right insertion holes.

In addition, a pair of second mounting parts 12, 12 are provided on the second portion 10b, rearward of the first mounting parts 11, 11. The second mounting parts 12, 12 are, for example, pivot shafts, which are inserted into a pair of left and right insertion holes provided in the toilet lid 30. This allows the toilet lid 30 to be rotatably supported relative to the casing 10. In this way, the second mounting parts 12, 12 are an example of a support part that rotatably supports the toilet lid 30. The second mounting parts 12, 12 may be insertion holes. In this case, it is sufficient that the toilet lid 30 is provided with a pair of left and right pivot shafts.

The first portion 10a is wider in the left-right direction and to the rear than the second portion 10b. In other words, the top surface of the first portion 10a is located to the left-right direction and to the rear than the second portion 10b.

The toilet seat 20 and the toilet lid 30 are rotatably supported on the casing 10. Specifically, the toilet seat 20 is rotatably supported on the first mounting parts 11, 11 of the casing 10, and the toilet lid 30 is rotatably supported on the second mounting parts 12, 12 of the casing 10.

Figures 1 to 4 show the toilet seat 20 and toilet lid 30 in a closed state. By rotating the toilet seat 20 and toilet lid 30 from this state, the toilet seat 20 and toilet lid 30 are brought into an upright state, i.e., the toilet seat 20 and toilet lid 30 are brought into an open state.

As shown in FIG. 5, the toilet seat 20 is provided at the front of the casing 10 and is located on the upper surface of the bowl portion of the toilet body 2 when closed.

The toilet lid 30 is formed, for example, from urea resin. The toilet lid 30 has a top plate portion 31 and a side plate portion 32. The top plate portion 31 and the side plate portion 32 are formed, for example, integrally.

The top plate portion 31 is a curved, single-plate portion. When the toilet lid 30 is closed, the top plate portion 31 covers the upper surfaces of the casing 10 and the toilet seat 20. In other words, when the toilet lid 30 is closed, the lower surface of the top plate portion 31 faces the upper surfaces of the casing 10 and the toilet seat 20. The rear portion of the top plate portion 31 that faces the upper surface of the casing 10 is curved in a generally upward convex shape, and the front portion that faces the upper surface of the toilet seat 20 is curved in a generally downward convex shape.

The side plate portion 32 is provided on the edge of the top plate portion 31, and covers the side of the toilet seat 20 when the toilet lid 30 is closed. Specifically, when the toilet lid 30 is closed, the side plate portion 32 extends downward from the edge of the top plate portion 31, and the inner surface of the side plate portion 32 faces the side surface 21 of the toilet seat 20.

The lower end of the side plate portion 32 is located above the upper surface of the casing 10. Specifically, the lower end surface 32a (see FIG. 9) of the side plate portion 32 faces the upper surface 15 (see FIG. 9) of the upper surface of the first portion 10a of the casing 10, which is located to the left and right of the second portion 10b.

In this manner, the toilet lid device 3 according to the embodiment has a configuration in which the lower end of the side plate portion 32 of the toilet lid 30 is located above the upper surface of the casing 10 (specifically, the upper surface 15 described above).

Here, a gap is provided between the lower end of the side plate portion 32 of the toilet lid 30 and the upper surface (upper surface 15) of the casing 10 so that the toilet lid 30 does not come into contact with the casing 10.

However, for example, when the toilet lid 30 is closed forcefully or when a load is applied from above, such as when a person stands on the toilet lid 30, the lower end of the side plate portion 32 of the toilet lid 30 may come into contact with the upper surface (upper surface 15) of the casing 10, causing the casing 10 to be damaged.

Therefore, in the toilet lid device 3 according to the embodiment, a cover portion 40 is provided on the upper surface of the casing 10. This makes it possible to prevent the casing 10 from being damaged by contact with the toilet lid 30.

The configuration of the cover portion 40 will be described below with further reference to Figs. 7 to 9. Fig. 7 is a plan view of the cover portion 40 according to the embodiment, and Fig. 8 is a perspective view of the cover portion 40 according to the embodiment. Also, Fig. 9 is an enlarged view of a portion of the side of the toilet device 1 according to the embodiment.

As shown in Figures 7 and 8, the cover portion 40 is configured as a separate member from the casing 10 and is detachable from the casing 10. By configuring the cover portion 40 to be detachable from the casing 10 in this way, if the cover portion 40 is damaged, for example, by contact with the toilet lid 30, it is possible to replace only the cover portion 40. Note that the cover portion 40 does not necessarily need to be detachable from the casing 10.

The cover section 40 covers the upper surface of the first section 10a of the upper surface of the casing 10 (see FIG. 6). Specifically, the cover section 40 includes a first cover member 41 and two second cover members 42. The first cover member 41 is a member that covers a portion of the upper surface of the first section 10a that is located behind the second section 10b. The second cover member 42 is a member that covers a portion of the upper surface of the first section 10a that is located to the side of the second section 10b (corresponding to the upper surface 15 shown in FIG. 9).

As shown in FIG. 9, the upper surface 42a of the second cover member 42 of the cover portion 40 covers the surface of the upper surface of the casing 10 that faces the lower end surface 32a of the side plate portion 32, specifically, the upper surface 15 of the first portion 10a located to the side of the second portion 10b.

As a result, even if the toilet lid 30 is forcefully closed or if a load is applied from above, such as when a person stands on the toilet lid 30, the lower end surface 32a of the side plate portion 32 will come into contact with the second cover member 42 of the cover portion 40, not the casing 10. Therefore, according to the toilet lid device 3 of the embodiment, damage to the casing 10 can be suppressed.

The second cover member 42 of the cover section 40 also covers the side surface 13 of the casing 10 at least forward of the second mounting section 12. In other words, the area of the side surface 13 of the casing 10 covered by the second cover member 42 is larger in front of the second mounting section 12 than behind or below the second mounting section 12.

When a load is applied from above to the toilet lid 30 and the side plate portion 32 comes into contact with the cover portion 40, it may bend (deform) and come into contact with the side surface 13 of the casing 10. The bending of the side plate portion 32 increases the further it is from the second attachment portion 12, which serves as the fulcrum for the toilet lid 30. Therefore, in the toilet lid device 3 according to the embodiment, not only the top surface of the casing 10 but also the side surface 13 of the casing 10 located forward of the second attachment portion 12 is covered with the second cover member 42. This can further prevent the casing 10 from being damaged.

The cover section 40 according to the embodiment is configured to be separable into a first cover member 41 and two second cover members 42. The part of the cover section 40 that is easily damaged by contact with the toilet lid 30 is the second cover member 42. By configuring the cover section 40 according to the embodiment to be separable into the first cover member 41 and the two second cover members 42, it becomes possible to replace only the second cover member 42, which is easily damaged.

In addition, the cover part 40 according to the embodiment has the first cover member 41, and is therefore able to protect the upper surface of the first part 10a located behind the second part 10b. The upper surface of the first part 10a located behind the second part 10b may come into contact with the toilet lid 30, for example, when the toilet lid 30 is in an open state and a load is applied to the toilet lid 30.

For example, if the cover section 40 is composed of only two second cover members 42, the worker must repeat the work of attaching the second cover members 42 to the casing 10 twice. In contrast, in the cover section 40 according to the embodiment, the two second cover members 42 are continuously connected by the first cover member 41, so the work of attaching the cover section 40 to the casing 10 is simpler than the above.

The first cover member 41 and the two second cover members 42 do not necessarily need to be separable, and may be formed integrally.

The cover unit 40 may be colored differently from the casing 10. In this way, by making the color of the cover unit 40 different from the color of the casing 10, the user can easily understand that the cover unit 40 is replaceable. Also, for example, by giving the cover unit 40 a color that is less noticeable when scratched compared to the color of the casing 10, the cover unit 40 can be maintained in a visually clean state for a longer period of time.

Figure 10 is an enlarged view of a portion of the rear surface of the toilet device 1 according to the embodiment. As described above, the side surface 2b of the toilet body 2 is inclined downward and inward. As shown in Figure 10, the side surface of the casing 10, specifically the side surface 13 of the first portion 10a, is located above the side surface 2b of the toilet body 2, and is inclined upward and outward from the lower end, which is the end portion on the toilet body 2 side.

In this way, by slanting the side surface 13 of the casing 10 outward from the bottom end upward, the area of the top surface of the casing 10 can be made larger. This ensures that the bottom end of the side plate portion 32 of the toilet lid 30 comes into contact with the cover portion 40 provided on the top surface of the casing 10 when the toilet lid 30 is closed, while preventing the toilet lid device 3 from becoming larger overall. In addition, by slanting the side surface 13 of the casing 10 in the same direction as the side surface 2b of the toilet body 2, the design can be improved.

In the above embodiment, the cover portion 40 covers substantially the entire upper surface of the first portion 10a, but it is sufficient that the cover portion 40 covers at least the surface of the first portion 10a that faces the lower end of the side panel portion 32 of the toilet lid 30.

As described above, the toilet lid device according to the embodiment (for example, toilet lid device 3) comprises a casing (for example, casing 10), a toilet seat (for example, toilet seat 20) and a toilet lid (for example, toilet lid 30) supported rotatably relative to the casing. The toilet lid comprises a top plate portion (for example, top plate portion 31) that covers the upper surfaces of the casing and the toilet seat when the toilet lid is closed, and a side plate portion (for example, side plate portion 32) that is provided on the edge of the top plate portion and covers the side surface of the toilet seat when the toilet lid is closed, and whose lower end is located above the upper surface of the casing. The toilet lid device according to the embodiment further comprises a cover portion (for example, cover portion 40) that is provided on at least the surface of the upper surface of the casing that faces the lower end of the side plate portion.

Therefore, the toilet lid device according to the embodiment can prevent the casing from being damaged by contact with the toilet lid.

Further advantages and modifications may readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
