Description

Technical Field

[0001] This invention relates to a toilet seat device for Western-style toilets. Background Technology

[0002] Previously, heated toilet seat devices installed on Western-style toilets were known (for example, see Patent Document 1). The heated toilet seat device 100 described in Patent Document 1 includes a toilet seat 200, a toilet lid 300, and a functional section 400. The toilet seat 200 and the toilet lid 300 are axially supported on the functional section 400 and can be opened and closed by manual rotation by the user.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2010-110573 However, when opening the toilet lid 300, the user inserts their hand (fingertips, etc.) between the toilet lid 300 and the toilet bowl 500 and lifts the toilet lid 300. Therefore, there is a concern that the hand may come into contact with the toilet bowl 500. If the hand comes into contact with the toilet bowl 500, there is a possibility that dirt from the toilet bowl 500 may adhere to the hand, or even if there is no dirt, the user may feel uncomfortable.

[0027] Hereinafter, preferred embodiments of the toilet seat device of the present invention will be described with reference to the accompanying drawings. Furthermore, the structures described below are not necessarily all essential elements of the present invention.

[0028] Figures 1-9 This invention represents a first embodiment in which a toilet seat device 1 is installed on the upper part of a Western-style bidet toilet T (hereinafter referred to as "toilet T"). The toilet seat device 1 is configured to include a main body 2, a toilet seat 3, and a toilet seat cover 4. Figure 1 As shown, on the left side face 5 of the main body 2 in this embodiment (refer to...) Figure 6 The main operating unit 6 is provided, which includes cleaning buttons such as a buttock button and a lower body button, as well as various operating buttons including a stop button. Figures 2-7 Not shown in the image.

[0029] Although not shown in the figure, the main body 2 contains a main body water inlet 7 that protrudes outward from the left side face 5 of the main body 2 (see reference). Figure 6 The system includes a water flow device for drawing in water, a movable cleaning nozzle device, a water heating device for heating the water, a toilet seat heating device for heating the toilet seat, a deodorizing device, and a control unit for controlling these devices. An exhaust port 9 for the deodorizing device is formed at the opening on the rear side 8 of the main body 2 (see reference). Figure 5 ).

[0030] The toilet seat 3 is rotatably supported by the main body 2. The upper surface 11 of the toilet seat 3 has a slightly inclined seat surface 13 that slopes downwards towards the central opening 12, making it easier for the user to sit down. Figure 3As shown, multiple (four in this embodiment) toilet seat legs 15 protrude from the lower surface 14 of the toilet seat 3, abutting against and supporting the upper surface of the toilet bowl T. The portions of the toilet seat legs 15 that abut against the upper surface of the toilet bowl T have an elongated oval shape.

[0031] like Figure 1 and Figure 3 As shown, when viewed from above, the front side portion 16 of the toilet seat 3 has a generally arc shape, and the left side portion 17 and right side portion 18 of the toilet seat 3 have a generally straight shape.

[0032] The toilet seat cover 4 is rotatably supported by a pivot on the main body 2. For example... Figures 1-9 As shown, the toilet seat cover 4 has a top plate portion 21, a front wall portion 22, a left side wall portion 23, and a right side wall portion 24. The top plate portion 21 is plate-shaped, and when viewed from above, the front end portion 25 has a generally arc-shaped shape, the rear end portion 26 has a straight shape, and the left end portion 27 and the right end portion 28 have slightly outwardly bulging arc-shaped portions.

[0033] The front wall portion 22 extends downward from the lower surface of the top plate portion 21, i.e., the lower surface 29 of the top plate. The portion of the lower surface 29 of the top plate that is forward of the front wall portion 22 is a handrest portion 30 for the user to rest their hand (fingertips, etc.) when opening the toilet seat cover 4. The width M of the handrest portion 30 (refer to...) Figure 8 The top plate portion 21 is widest between its foremost end 31 and the front wall portion 22, and gradually narrows towards the left wall portion 23 (left end 27 side) and the right wall portion 24 (right end 28 side) (see reference). Figure 9 On the left and right sides of the front wall portion 22, there are left front wall portions 32 and right front wall portions 33, where the width M of the handle portion 30 narrows sharply and the handle portion 30 disappears. The rear end portion of the left front wall portion 32 is the left boundary portion 34 without the handle portion 30, and the rear end portion of the right front wall portion 33 is the right boundary portion 35 without the handle portion 30.

[0034] The left wall portion 23 extends downward from the left end 27 of the top plate portion 21, and no handle portion 30 is formed on the left wall portion 23 (left end 27). The right wall portion 24 extends downward from the right end 28 of the top plate portion 21, and no handle portion 30 is formed on the right wall portion 24 (right end 28).

[0035] like Figure 6 and Figure 7 As shown, the front wall portion 22 is formed at an angle such that the lower side is located in front of the upper side (the side of the top plate portion 21). Therefore, the angle θ formed by the front wall portion 22 and the armrest portion 30 is an acute angle.

[0036] like Figure 1 and Figure 8As shown, a plurality of (two in this embodiment) cover support portions 36 are formed on the front wall portion 22 at a position slightly behind the left boundary portion 34 and the right boundary portion 35. The cover support portions 36 abut against the upper surface 11 of the toilet seat 3 when the toilet seat cover 4 is closed, thereby supporting the toilet seat cover 4.

[0037] When the toilet seat cover 4 is closed, the toilet seat 3 is covered by the toilet seat cover 4 and cannot be seen when viewed from above, from the front, from the left, or from the right. From this position, the user can lift the toilet seat cover 4 by placing their hand on the handle 30, thereby opening the toilet seat cover 4. At this time, the user places their hand under the top plate 21 (handle 30) instead of under the toilet seat cover 4, thus opening the toilet seat cover 4 without touching the toilet bowl T.

[0038] As described above, the toilet seat device 1 of this embodiment includes: a main body 2; a toilet seat 3 rotatably supported on the main body 2; and a toilet seat cover 4 rotatably supported on the main body 2 and covering the toilet seat 3 from above. The toilet seat cover 4 has a top plate portion 21 and a front wall portion 22 protruding downward from the top plate portion 21. The front wall portion 22 is located rearward of the foremost end portion 31 of the top plate portion 21. The portion of the lower surface 29 of the top plate portion 21 that is forward of the front wall portion 22 is a handle portion 30. Therefore, the toilet seat cover 4 can be opened and closed by placing one's hand on the handle portion 30, which is a certain distance away from the toilet bowl T, making it difficult to contact the toilet bowl T when opening and closing the toilet seat cover 4.

[0039] Furthermore, in this embodiment, the width M of the handrest portion 30 of the toilet seat device 1 is longest at the foremost end 31, and narrows towards the left side wall 23 and right side wall 24 of the toilet seat cover 4. Therefore, the foremost end 31, considered the part with the most handrest, has the longest width M, making it easy to place the hand. Additionally, by making the range of the handrest portion 30 longer in the left-right direction, the area where the hand can be placed is expanded, allowing the user to place their hand in a desired position within the handrest portion 30. Moreover, even when the handrest portion 30 is formed relatively thin, increasing its range increases its strength.

[0040] Furthermore, in this embodiment, the angle θ formed between the armrest portion 30 and the front wall portion 22 of the toilet seat device 1 is an acute angle. Therefore, it is not necessary to extend the front end portion 25 of the top plate portion 21 of the toilet seat cover 4 forward significantly to ensure the width M of the armrest portion 30.

[0041] Figures 10-19A toilet seat device 1A, as a second embodiment of the present invention, is shown, but the same reference numerals are used for the same parts as in the first embodiment described above, and detailed descriptions are omitted. Handles 41 and 42 protrude from the front side portion 16A of the toilet seat 3A of the toilet seat device 1A. Specifically, handle 41 protrudes from approximately the midpoint between the left side portion 17A and the foremost portion 43 of the toilet seat 3A. Handle 42 protrudes from approximately the midpoint between the right side portion 18A and the foremost portion 43 of the toilet seat 3A.

[0042] like Figure 17 As shown, handles 41 and 42 are formed with the same shape and are positioned in a position symmetrical to the imaginary center line L in the left-right direction relative to the toilet seat 3A. The protruding length D of handles 41 and 42 is the length to which the user can rest their hands (fingertips, etc.). Normally, when the user sits on the toilet seat 3A, the back of the knee and calf are separated from the toilet seat 3A to a certain extent, and the protruding length D is short, so it is difficult for the user's legs to reach the handles 41 and 42. In addition, even when the back of the knee and calf are in contact with the toilet seat 3A, because the handles 41 and 42 are positioned offset to the left and right from the front part 43, it is difficult for the user's legs to reach the handles 41 and 42.

[0043] like Figure 15 and Figure 16 As shown, in side views, handle 41 is formed into a horizontally elongated, approximately oblong shape. The upper surface 44 of the handle is lower than the seat surface 13A, and the lower surface 45 of the handle is higher than the lower surface 14A of the toilet seat. Handle 42 is also formed into a horizontally elongated, approximately oblong shape. The upper surface 46 of the handle is lower than the seat surface 13A, and the lower surface 47 of the handle is higher than the lower surface 14A of the toilet seat.

[0044] The toilet seat cover 4A of the toilet seat device 1A has two handle recesses 48 and 49 formed on the front wall portion 22A. Handle recess 48 is formed on the left front wall portion 32A and its front side, and handle recess 49 is formed on the right front wall portion 33A and its front side. Handle recesses 48 and 49 are of the same shape, formed by shortening the length H of the front wall portion 22A. The length H1 of the front wall portion 22A with handle recesses 48 and 49 is set to a length that prevents the front wall portion 22A from contacting the handles 41 and 42 when the toilet seat cover 4A is closed. That is, when the toilet seat cover 4A is closed, a small gap is formed between the handles 41 and 42 and the handle recesses 48 and 49.

[0045] When the toilet seat cover 4A is closed, the toilet seat 3A is covered by the toilet seat cover 4A, such as Figure 11 As shown, toilet seat 3A is not visible from above, but as Figure 15 as well as Figure 16As shown, handles 41 and 42 are visible when viewed from the left and right sides. From this position, the user can lift the toilet seat cover 4A by placing their hand on the armrest 30, thereby opening the toilet seat cover 4A. Alternatively, from the position where the toilet seat cover 4A is open, the user can lift the toilet seat 3A by placing their hand on the lower surface 45 or 47 of either handle 41 or handle 42, thereby opening the toilet seat 3A. Handles 41 and 42 protrude from the front side portion 16 of the toilet seat 3A and are positioned higher than the lower surface 14A of the toilet seat. Therefore, by placing their hand under the handles 41 and 42 rather than under the toilet seat 3A, the user can open the toilet seat 3A without touching the toilet bowl T.

[0046] As described above, the toilet seat device 1A of this embodiment includes: a main body 2; a toilet seat 3A rotatably supported on the main body 2; and a toilet seat cover 4A rotatably supported on the main body 2 and covering the toilet seat 3A from above. The toilet seat cover 4A has a top plate portion 21 and a front wall portion 22A protruding downward from the top plate portion 21. The front wall portion 22A is located rearward of the foremost end portion 31 of the top plate portion 21. The portion of the lower surface of the top plate portion 21, i.e., the lower surface 29 of the top plate, that is, the portion forward of the front wall portion 22A, is a handle portion 30. Therefore, the toilet seat cover 4A can be opened and closed by placing one's hand on the handle portion 30, which is a certain distance away from the toilet bowl T, making it difficult to contact the toilet bowl T during the opening and closing of the toilet seat cover 4A.

[0047] Furthermore, in the toilet seat device 1A of this embodiment, the width M of the handrest portion 30 is longest at the foremost end 31, and narrows towards the left side wall 23 and right side wall 24 of the toilet seat cover 4A. Therefore, the width M of the handrest portion 30 at the foremost end 31, which is considered the part where the hand rests the most, can be maximized, making it easy to place the hand. Additionally, by making the range of the handrest portion 30 longer in the left-right direction, the area where the hand can rest can be expanded, allowing the user to place their hand in a desired position within the handrest portion 30. Moreover, even when the handrest portion 30 is formed relatively thinly, its strength can be increased by expanding its range.

[0048] Furthermore, in this embodiment, the angle θ formed between the armrest portion 30 and the front wall portion 22A of the toilet seat device 1A is an acute angle. Therefore, it is not necessary to extend the front end portion 25 of the top plate portion 21 of the toilet seat cover 4A forward significantly to ensure the width M of the armrest portion 30.

[0049] Furthermore, in this embodiment, the toilet seat device 1A has handles 41 and 42 protruding from the front side portion 16A of the toilet seat 3A. Therefore, the toilet seat 3A can be opened and closed by placing one's hand on the handles 41 and 42. In addition, since the handles 41 and 42 protrude from the front side portion 16A of the toilet seat 3A, a certain distance can be maintained between the hand resting position and the toilet bowl T, making it difficult for the hand to touch the toilet bowl T when opening and closing the toilet seat 3A.

[0050] Furthermore, in this embodiment, the toilet seat device 1A has handle recesses 48 and 49 formed on the toilet seat cover 4A. When the toilet seat cover 4A is closed, the handles 41 and 42 are located below the handle recesses 48 and 49. Therefore, when the toilet seat cover 4A is closed, the toilet seat cover 4A can be prevented from contacting the handles 41 and 42.

[0051] The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the shape, size, material, color, etc. of each component constituting the toilet seat device can be appropriately changed.
