Description

Technical Field

[0001] Embodiments of the present invention relate to flush toilets. Background Technology

[0002] Previously, flush toilets were known in which the panel component and the toilet body were held together by magnetic force in a flush toilet in which the functional part was covered by the panel component (for example, see Patent Document 1).

[0003] Patent Document 1: Japanese Patent Application Publication No. 2020-165173

[0004] When attempting to mount magnets or magnetic objects onto a ceramic toilet body as described in Patent Document 1, adhesives are typically used. However, the method of using adhesives presents problems in terms of workability, such as numerous steps and difficulty in rework. Summary of the Invention

[0005] One aspect of this embodiment is to enable easy installation of sheet metal parts onto the toilet body without the use of adhesives.

[0006] One embodiment of the flush toilet is characterized by having: a toilet body having a basin for receiving waste; a functional part disposed at the rear of the toilet body; a panel member covering the side of the functional part; a magnet disposed on the panel member; and a magnetic body disposed on a mounting part of the toilet body, the magnetic body being elastically deformable to be mounted on the mounting part in a manner that clamps the mounting part.

[0007] According to the structure described above, the magnet fits into the mounting part of the toilet body without the use of adhesive, thus requiring fewer steps and making the installation of the magnet easy. Furthermore, rework is possible if the installation position of the magnet and the toilet body is inconsistent, resulting in a flushing toilet with excellent workability.

[0008] The magnetic body is characterized by having: an adsorption part that adsorbs onto a magnet; a clamping part that is opposite to the adsorption part across the mounting part; and a connecting part that connects the adsorption part and the clamping part.

[0009] According to the structure described above, the mounting part is fixed by clamping the magnetic body using the elastically deformable adsorption and clamping parts, thereby increasing the contact area between the magnetic body and the mounting part. The increased contact area leads to increased friction between the magnetic body and the mounting part, thus preventing the magnetic body from detaching from the mounting part.

[0010] The feature is that the clamping part has an inclined part that extends from the end on the connecting part side toward the adsorption part when the magnet is not installed on the toilet body.

[0011] According to the structure described above, after the magnetic material is mounted on the mounting portion, the angle between the connecting portion and the inclined portion becomes larger than before the magnetic material is mounted on the mounting portion, thus generating a restoring force in which the inclined portion attempts to return to its original shape. Furthermore, through the restoring force generated by the inclined portion, the adsorption portion and the mounting portion become more closely connected. Therefore, the holding force of the magnetic material relative to the mounting portion can be increased.

[0012] The feature is that the clamping part has an abutting part, which is provided at the front end of the inclined part and contacts the mounting part. When the magnetic body is installed on the toilet body, the inclined part extends from the end of the connecting part toward the adsorption part.

[0013] According to the structure described above, the force applied from the mounting portion to the contact portion generates torque at the inclined portion, connecting portion, and adsorption portion, starting from the contact portion, thereby further tightening the adsorption portion and the mounting portion. This increases the holding force of the magnetic material relative to the mounting portion.

[0014] The feature is that the magnetic body has a fixing part, which is installed on the toilet body at the end opposite to the end of the connecting part.

[0015] With the structure described above, the ends of the magnetic body are fixed to the toilet body at both ends, thus allowing for close contact with the mounting portion even at locations away from the connecting portion within the magnetic body. Furthermore, by providing two fixing portions, the stress borne by the magnetic body can be distributed.

[0016] The toilet body has ribs that protrude from the mounting portion and restrict the rearward movement of the magnet.

[0017] According to the structure described above, when the magnetic body moves backward by internal or external force, it can prevent the magnetic body from falling off the toilet body.

[0018] The effects of the invention

[0019] According to the flushing toilet of the present invention, sheet metal parts can be easily installed on the toilet body without the use of adhesives. Attached Figure Description

[0029] Hereinafter, a summary of the flush toilet 1 according to the embodiment will be described with reference to the accompanying drawings.

[0030] In addition, in the inclusion Figure 1 For ease of explanation, some diagrams show a 3D orthogonal coordinate system including the Z-axis, with the vertically upward direction (above) as positive. In this case, the positive direction of the X-axis is defined as left, the negative direction as right, the positive direction of the Y-axis as front, the negative direction as back, the positive direction of the Z-axis as upward, and the negative direction as downward. Furthermore, the X-axis direction is 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. Additionally, the left-right direction corresponds to the width of the flush toilet 1.

[0031] like Figure 1 , Figure 2 As shown, the flush toilet 1 has a toilet body 3, a functional part 5, a sanitary cleaning device 7, a panel part 9, a toilet seat part 10, and a cover part 15. The toilet body 3 is made of ceramic. However, the toilet body 3 is not limited to ceramic; for example, it may be made of resin or a combination of ceramic and resin. Figure 1 This is a side view of the flush toilet 1 according to the embodiment. Figure 2 This is a side view of the flush toilet 1 according to the embodiment, with part of the panel component 9 omitted.

[0032] The toilet body 3 has a basin 4 (see reference). Figure 4 ), edge 11 and drainage bend 13.

[0033] A functional unit 5 is provided at the rear of the toilet body 3. The functional unit 5 supplies water to the basin 4 and the sanitary cleaning device 7 of the toilet body 3. The functional unit 5 includes a water storage tank (not shown) and a pressure pump (not shown). Regarding the water supply, the functional unit 5 pressurizes the cleaning water stored in the water storage tank by the pressure pump and sprays it out at a large flow rate from the jet nozzle (not shown) to the basin 4.

[0034] The sanitary cleaning device 7 is equipped with a local cleaning device (not shown) including a nozzle device (not shown), which sprays cleaning water towards the user's area above the basin 4. Additionally, the sanitary cleaning device 7 includes a water storage section (not shown) for storing the cleaning water supplied to the local cleaning device, a heater (not shown) for heating the cleaning water in the water storage section to a suitable temperature to become warm water, a ventilation fan (not shown), a deodorizing fan (not shown), a warm air fan (not shown), and a control unit (not shown) for controlling these components.

[0035] The basin portion 4 is the part that receives waste and is concave in shape. A border portion 6 is formed at the upper edge of the basin portion 4 (see reference). Figure 4 The frame portion 6 has a frame spray nozzle 8 for spraying cleaning water (see reference). Figure 4 The frame portion 6 allows the cleaning water sprayed from the frame nozzle 8 to flow along the upper edge of the basin portion 4, forming a swirling flow within the basin portion 4. Furthermore, a water guide passage (not shown) formed on the upstream side is connected to the frame nozzle 8, through which cleaning water from the cleaning water supply pipe (not shown) is supplied.

[0036] A panel component 9 is provided at the rear of the toilet body 3 and on the side of the functional part 5. The panel component 9 is used to prevent external damage to the functional part 5 or sewage intrusion. The panel component 9 is made of resin.

[0037] The toilet seat 10 is located on the upper part of the toilet body 3, providing a place for the user to sit when using the flush toilet 1. The toilet seat 10 rotates with its rear side as a fulcrum, thereby allowing it to be opened and closed.

[0038] Like the toilet seat 10, the lid 15 is positioned on the upper part of the toilet body 3, covering the upper surface of the basin 4 containing the toilet body 3 from above. Like the toilet seat 10, the lid 15 rotates with its rear side as a fulcrum, thereby allowing it to open and close. Furthermore, when closed, the lid 15 covers the upper surface of the toilet body 3 from above and also covers the toilet seat 10 from above.

[0039] Furthermore, the flushing toilet 1 has a first holding part 21 and a second holding part 23. The first holding part 21 magnetically holds the side of the panel component 9 and the toilet body 3 together, while the second holding part 23 magnetically holds the functional part 5 and the side of the panel component 9 together. The second holding part 23 is composed of a magnet 33 provided on the side of the panel component 9 and a sheet metal part 31 provided on the functional part 5 and serving as a magnetic body that is magnetically attracted.

[0040] The first retaining part 21 will be described in detail. The first retaining part 21 is composed of a magnet 25 and a sheet metal part 27 that is a magnetic body attracted by magnetic force. The first retaining part 21 is provided at the boundary A between the toilet body 3 and the panel member 9. The boundary A is the part where the toilet body 3 and the panel member 9 overlap when the panel member 9 is properly provided on the toilet body 3. The boundary A is the part where, when viewed from the side, the side of the toilet body 3 changes with a gentle curvature from the front to the rear side, and more specifically, it is the part with a step that is recessed inward towards the toilet body 3.

[0041] Next, refer to Figures 3-8 The installation of sheet metal part 27 and mounting part 12, and the installation of panel part 9 and toilet body 3 are explained. Figure 3 This is a diagram showing the panel component 9 involved in the embodiment as viewed from the inside side. Figure 4 This is a rear perspective view of the flush toilet 1 according to the embodiment, omitting the panel component 9, etc. Figure 5 The following diagram is an omission of the panel component 9, etc., of the flush toilet 1 according to the embodiment. Figure 6 This is a rear view of the sheet metal part 27 of the flush toilet 1 according to the embodiment. Figure 7 This is a rear view showing the sheet metal part 27 and the area near the top of the mounting part 12 of the flush toilet 1 according to the embodiment. Figure 8 This is a rear view showing the sheet metal part 27 and the area below the mounting part 12 of the flush toilet 1 according to the embodiment.

[0042] Magnet 25 is mounted on panel component 9. Magnet 25 is provided at two locations on the front end side of the inner side of panel component 9, that is, near the junction of device body 3 and panel component 9. The two locations of magnet 25 are one located at the upper end and the center of panel component 9, and one located at the lower end and the center of panel component 9.

[0043] Furthermore, the magnet 25 does not need to be set in two places. It can be set to cover the entire boundary A in the vertical direction, or one magnet can be set in the center of the boundary A in the vertical direction.

[0044] Next, the sheet metal part 27 will be described. Sheet metal part 27 is mounted on the toilet body 3. Sheet metal part 27 is mounted on the mounting portion 12 of the toilet body 3 in the boundary portion A. The mounting portion 12 extends rearward from the rear end face of the edge portion 11. The mounting portion 12 has an outer surface 12a extending vertically, an upper surface 12b extending inward from the upper end of the outer surface 12a, and an inner surface 12c extending downward from the inner end of the upper surface 12b. In the mounting portion 12, a protrusion 12j with a predetermined thickness is formed at the upper end side between the outer surface 12a and the inner surface 12c. The connecting portions (corners) of each surface have curvature.

[0045] Sheet metal part 27 is formed from a thin sheet of metal capable of elastic deformation. Sheet metal part 27 includes: an adsorption portion 27a, which, when viewed from the side, is configured to cover the outer surface 12a of the mounting portion 12 and extends vertically; a connecting portion 27b, which extends inward from the upper end of the adsorption portion 27a and is located above the upper surface 12b of the mounting portion 12; and a clamping portion 27c, which extends downward from the inner end of the connecting portion 27b and is located inside the inner surface 12c of the mounting portion 12. The clamping portion 27c includes: an inclined portion 27d, which is connected to the connecting portion 27b and extends toward the adsorption portion 27a and the inner surface 12c; and an anti-inclined portion 27e, which is connected to the inclined portion 27d and extends away from the adsorption portion 27a and the inner surface 12c. The sheet metal part 27 clamps the protrusion 12j of the mounting part 12 via the suction part 27a, the clamping part 27c, and the connecting part 27b on its upper side, thereby fixing it to the mounting part 12. When the sheet metal part 27 is clamped into the mounting part 12, it expands by separating the suction part 27a and the clamping part 27c. If the sheet metal part 27 is hooked onto the outer surface 12a, the upper surface 12b, and the inner surface 12c of the mounting part 12, the sheet metal part 27 elastically deforms due to shape memory, thereby exerting a holding force on the mounting part 12 and fixing the sheet metal part 27 to the mounting part 12. As a result, the sheet metal part 27 fits into the mounting part 12 of the toilet body 3 without the use of adhesive, thus reducing the number of work steps and making it easy to install the sheet metal part 27. In addition, if the installation position of the sheet metal part 27 and the toilet body 3 is not good, rework is possible, thus providing a flushing toilet 1 with good workability.

[0046] Furthermore, by using the elastically deformable adsorption portion 27a and clamping portion 27c to fix the mounting portion 12 into the sheet metal part 27, the contact area between the sheet metal part 27 and the mounting portion 12 can be increased. The increased contact area leads to increased friction between the sheet metal part 27 and the mounting portion 12, thus preventing the sheet metal part 27 from detaching from the mounting portion 12.

[0047] The mounting portion 12 has one recess 12i on the upper and lower parts of the outer surface 12a in the vertical direction, where the outer surface 12a is recessed inward. Additionally, the sheet metal part 27 has one recess 27i on the upper and lower parts of the adsorption portion 27a in the vertical direction, where the adsorption portion 27a is recessed inward. This configuration is such that when the sheet metal part 27 is assembled to the toilet body 3, the recess 12i is enclosed within the recess 27i when viewed from the rear. When the panel component 9 is assembled to the toilet body 3, the magnet 25 of the panel component 9 is located in the recess 27i. Therefore, when the panel component 9 is assembled to the toilet body 3, the thickness of the magnet 25 in the width direction can be reduced, and the amount of protrusion of the panel component 9 in the width direction can be reduced.

[0048] Furthermore, the inclined portion 27d of the sheet metal part 27, when the sheet metal part 27 is not installed on the toilet body 3, such as Figure 7 As shown by the dashed line, it extends from the end on the connecting portion 27b side toward the adsorption portion 27a. Furthermore, in Figure 7 In the diagram, the inclined portion 27d of the sheet metal part 27 before installation onto the toilet body 3 is represented by a dashed line, while the inclined portion 27d of the sheet metal part 27 after installation onto the toilet body 3 is represented by a solid line.

[0049] Regarding the angle of the inclined portion 27d of the sheet metal part 27, compared to before the sheet metal part 27 is installed onto the protrusion 12j of the mounting portion 12, the angle after the sheet metal part 27 is installed onto the mounting portion 12 is larger, thus generating a restoring force in which the inclined portion 27d attempts to return to its original shape. Furthermore, through the restoring force generated by the inclined portion 27d, the adsorption portion 27a and the mounting portion 12 are brought into closer contact. Therefore, the holding force of the sheet metal part 27 relative to the mounting portion 12 can be improved.

[0050] In addition, such as Figure 7 As shown by the dashed line, in the state before the sheet metal part 27 is installed onto the mounting part 12, the curvature of the connection portion between the connecting portion 27b and the clamping portion 27c of the sheet metal part 27 is greater than the curvature of the connection portion between the upper surface 12b and the inner surface 12c of the mounting part 12. Therefore, when the sheet metal part 27 is installed onto the mounting part 12, the connection portion between the connecting portion 27b and the clamping portion 27c is pulled into the mounting part 12. As a result, the holding force of the sheet metal part 27 relative to the mounting part 12 can be increased.

[0051] Furthermore, when the sheet metal part 27 is installed on the toilet body 3, the inclined portion 27d is also inclined relative to the inner side 12c. Here, the part where the front end of the inclined portion 27d contacts the mounting portion 12 is referred to as the abutment portion 27f.

[0052] Therefore, the force applied from the mounting portion 12 to the contact portion 27f generates torque at the inclined portion 27d, the connecting portion 27b, and the adsorption portion 27a, thereby further tightening the adsorption portion 27a and the mounting portion 12. As a result, the holding force of the sheet metal part 27 relative to the mounting portion 12 can be improved.

[0053] Next, refer to Figure 4 and 8 The installation of sheet metal part 27 and the lower part of mounting section 12 will be explained. Figure 8 This is a rear view showing the sheet metal part 27 and the area below the mounting part 12 of the flush toilet 1 according to the embodiment.

[0054] A fixing portion 27h is located at the end opposite to the end of the connecting portion 27b below the sheet metal part 27. The fixing portion 27h extends inward from the adsorption portion 27a in such a way that it covers the lower end of the rear surface 12f of the mounting portion 12. When viewed from above, the fixing portion 27h forms an L-shape, and the outer surface 12a and the rear surface 12f of the mounting portion 12 contact and are surrounded by the two L-shaped surfaces of the fixing portion 27h.

[0055] Furthermore, the fixing part 27h has a protrusion 27j that protrudes rearward from the lower end. A screw hole 27k is formed in the protrusion 27j. The fixing part 27h is fixed to the bottom 3a provided at the rear end of the toilet body 3 by inserting a screw into the screw hole 27k. Thus, the fixing part 27h is installed on the toilet body 3.

[0056] Thus, the ends of the sheet metal part 27 are fixed to the toilet body 3 at both ends, so that even in the part of the sheet metal part 27 away from the connecting part 27b, it can be closely connected to the mounting part 12. In addition, by providing two fixing parts, the stress borne by the sheet metal part 27 can be distributed.

[0057] In the modified example of the flush toilet 1, such as Figure 9 As shown, the mounting portion 12 has a rib 12g extending upward from the rear end of the upper surface 12b of the mounting portion 12. Figure 9 This is a side view showing the area near the upper surface 12b of the mounting portion 12 of the toilet 1 involved in the modified example.

[0058] The connecting portion 27b covers the front of the upper surface 12b, and the rib 12g extends from the upper surface 12b, which is located behind the connecting portion 27b. Therefore, when the sheet metal part 27 moves in a direction orthogonal to the mounting portion 12, the connecting portion 27b contacts the rib 12g, thereby preventing the sheet metal part 27 from detaching from the toilet body 3. Furthermore, the rib 12g protrudes upward from the upper surface 12b, thus preventing the rib 12g from contacting the panel member 9, and the panel member 9 from expanding relative to the toilet body 3 in the width direction, thus preventing a step from forming between the panel member 9 and the toilet body 3.

[0059] Furthermore, the rib 12g is not limited to extending upward from the upper surface 12b, but may also extend outward from the rear region of the outer side 12a, or extend inward from the inner side 12c.

[0060] Further effects and variations can be readily derived by those skilled in the art. Therefore, the invention is not limited to the specific details and representative embodiments described above. Thus, various modifications can be made without departing from the spirit or scope of the comprehensive concept of the invention as defined by the appended claims and their equivalents.
