Description

  The present invention relates to a warm water cleaning toilet seat, and more particularly to a technique for mounting a control board as a wiring means of an electronic device in a main body.

  Conventionally, a control board as a wiring means of an electronic device mounted in a main body of a warm water washing toilet seat is designed to be horizontally oriented on a portion where a space in the main body can be secured, for example, an upper portion in the main body. (See, for example, Patent Document 1).

  However, in the conventional example shown in Patent Document 1, since the control board is arranged horizontally in the upper part in the main body, the heat radiation from the control board stops at the upper part in the main body, and the element on the control board There is a possibility of adverse effects, especially when it is placed near the hot water tank in the main unit, water can splash on the control board due to water leakage or condensation from the connection part of the water supply hose discharged from the hot water tank There is also a possibility that the water or dust once scattered on the control board remains stored on the horizontal and horizontal control board, resulting in an uncontrollable situation. Further, conventionally, when the control board is horizontally placed, the round hole-shaped screw holes provided at the four corners of the control board are fixed to the four screw holes provided in the main body. There are 4 stop points, and it takes time to assemble, and if there is an error in the position of the screw hole part and the screw hole part of the control board, there is a possibility that the control board will be distorted by screwing. There are problems such as adversely affecting elements on the control board. In addition, the horizontal control board occupies a large area in the main unit, which is a harmful component when viewed from other parts, and the problem of poorer assembly and the control board placed horizontally on the top of the main unit There is also a problem that the heat radiation efficiency is further deteriorated due to the influence of heat radiated from the parts.

  As another conventional example, it is known that a control board is erected in a vertical direction in a main body (see, for example, Patent Document 2).

However, in the conventional example shown in Patent Document 2, when the control board is placed vertically, the control board cannot be attached without causing distortion.

  The present invention has been invented in view of the above-described conventional problems, and when the control board is placed vertically, even when the control board is fixed with screws, it is possible to prevent the control board from being distorted, and to improve assembly. An object of the present invention is to provide an excellent warm water washing toilet seat.

In order to solve the above-mentioned problems, the present invention is a warm water washing toilet seat in which a control board 4 as a wiring means of an electronic device is installed in a vertically placed state in a main body 2, and the main body 2 side has an upper end portion and a lower end portion. part of the left and right pair of slits circumferential grooves 3 which opening width is formed gradually narrower substantially V-shaped groove toward the provided, D · longitudinal with respect to the respective slits circumferential grooves 3 in the lower half of the control board 4 movement of the lower half of the plugged and the control board in the vertical direction B in a state in which a gap is provided a pair of right and left insertion portions 5 Ru inserted so that a state of being stopped by the bottom of the slit longitudinal grooves in the lateral C At the same time, a mounting piece 8 having a concave portion 7 whose front end opens from the upper half of the control board 4 toward the front F or the rear E is provided so as to face the concave portion 7 of the mounting piece 8 on the body 2 side. It is characterized in that a screw hole portion 9 opened upward is provided.

By adopting such a configuration, the slit vertical groove 3 is formed in a substantially V-shaped groove shape. Therefore, in a state where the insertion portion 5 provided in the lower half portion of the control board 4 is inserted into the slit vertical groove 3, The movement of the lower half of the control substrate 4 in the front-rear direction D is stopped by the lower part of the slit vertical groove 3. That is, the upper half of the control board 4 is allowed to move slightly in the front / rear direction D and the left / right C, and the lower half of the control board 4 is temporarily held by the slit vertical groove 3. Even if the concave portion 7 and the screw hole portion 9 are displaced in the front-rear direction D or the left-right direction C, the positional displacement can be easily corrected by the movement of the upper half of the control board 4 in the front-rear direction D and the left-right direction C. . Therefore, when the mounting screw 10 passes through the recess 7 of the mounting piece 8 and is fastened to the screw hole 9, an excessive tightening force is not applied to the control board 4, and the distortion of the control board 4 is effectively generated. Can be prevented. In addition, by occupying the control board 4 vertically, the area occupied by the control board 4 in the main body 2 can be reduced. Therefore, the control board 4 does not become a harmful part as viewed from other parts, and the mounting screw Since the number of attachment points by 10 can be reduced as compared with the prior art, the assemblability of the warm water washing toilet seat 1 becomes very good. In other words, the mounting screw 10 only needs to restrain the movement of the upper half of the control board 4, and the number of places where the control board 4 is restrained by the mounting screw 10 can be reduced. In addition, the number of mounting pieces 8 protruding from the control board 4 can be reduced, and the configuration of the control board 4 can be further simplified.

In the warm water cleaning toilet seat according to the present invention, when the control board is placed vertically, the control board is temporarily held in a state in which the control board can be moved back and forth, and left and right, so that the positional deviation between the mounting piece and the screw hole portion can be reduced. Can be corrected. Therefore, when the mounting screw is passed through the recess of the mounting piece and fastened to the screw hole, an excessive tightening force is not applied to the control board, and the distortion of the control board can be effectively prevented. is there. In addition, the number of places where the control board is restrained by the mounting screws can be reduced, the number of mounting pieces protruding from the control board can be reduced, and the configuration of the control board can be further simplified.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The warm water washing toilet seat 1 of this embodiment is installed in the rear upper surface side of the toilet bowl 11, as shown in FIG. 30 in the figure is a toilet lid.

  The housing 12 of the main body 2 of the warm water flush toilet seat 1 is divided into a base portion 12a fixed to the toilet 11 and a cover portion 12b fitted to the base portion 12a, and the inside is shown in FIG. Thus, the hot water tank 13 is installed close to the front side. The warm water tank 13 has a discharge unit 14 for discharging water for use in the toilet 11 and water for bidet washing / wet washing.

  Further, on the rear E of the hot water tank 13, a control board 4 as a wiring means of the electronic device is arranged vertically so as to approach the rearmost side in the main body 2. The control board 4 is made of a printed wiring board, for example. In this example, as shown in FIGS. 1 and 2, the width H 1 of the upper half of the outer peripheral frame 15 of the control board 4 is wider (H 1> H 2) than the width H 2 of the lower half. The effective area of the entire control board 4 can be secured large while reducing the installation area of the outer peripheral frame 15.

  Insertion sections 5 that are long in the vertical direction are provided at both end portions of the lower half of the outer peripheral frame 15 of the control board 4. As shown in FIG. 2B, the insertion portion 5 is formed in a T-shape in plan view having a wide retaining piece 5a at the tip.

  On the other hand, a pair of left and right ribs 6 and 6 are erected from the bottom surface on the main body 2 side. A slit vertical groove 3 is formed in each of the ribs 6 and 6. Here, the slit vertical direction is formed so that a predetermined gap (gap G1 between front and rear D and gap G2 between right and left C in FIG. 2B) is formed between the insertion portion 5 of the control board 4 and the slit vertical groove 3. The width of the groove 3 is slightly wider than the insertion portion 5. Furthermore, as shown in FIG. 1, the slit vertical groove 3 of this example is formed in a substantially V-shaped groove shape whose opening width gradually decreases from the upper end to the lower end. And in the state which inserted the insertion part 5 in the slit vertical groove 3, the insertion part 5 will be in the state which does not remove | deviate from the slit vertical groove 3 by arrange | positioning the retaining piece 5a of the insertion part 5 on the outer side of the rib 6, In this state, at least the upper half of the control board 4 has the front-rear direction D and the left-right direction C (hereinafter referred to as “front-rear direction”) due to the gaps G1, G2 (FIG. 2B) between the slit vertical groove 3 and the insertion portion 5. D and left and right C ”)) are temporarily held in a state where they can move slightly.

  Further, a pair of left and right mounting pieces 8 project from both end portions of the upper half of the outer peripheral frame 15 of the control board 4. In this example, a substantially U-shaped recess 7 that opens toward the rear E is formed at the front end of the left mounting piece 8 in FIG. 1, and the front end of the right mounting piece 8 in FIG. A substantially U-shaped concave portion 7 opening toward F is formed. Furthermore, each recessed part 7 is long formed in the front-back D, and can absorb the position shift of the front-rear D with the recessed part 7 and the screw hole part 9 by the side of the main body 2. FIG. In addition, since the positional deviation of the front-rear D between the recessed part 7 and the screw hole part 9 on the main body 2 side is also absorbed by the movement of the control board 4 in the front-rear D, it is not always necessary to form the recessed part 7 long in the front-rear D. For example, it may be a short C-shape. In short, the recessed part 7 should just be opening shapes other than the round hole opened to the front F or the back E. As shown in FIG.

  Further, a pair of left and right bosses 16, 16 are provided in the vicinity of the pair of left and right slit vertical grooves 3, and a female screw-like screw hole portion 9 opened upward is formed on the upper end surface of each boss 16. Is formed. Each screw hole 9 is formed at a position facing the recess 7 of the mounting piece 8 of the control board 4.

  When the control board 4 is placed vertically, as shown in FIGS. 1 to 2, the left and right C insertion portions 5 of the control board 4 are perpendicular to the left and right C slit vertical grooves 3 on the main body 2 side. Plug into B. At this time, gaps G1 and G2 of front and rear D and left and right C are secured between the slit vertical groove 3 and the insertion portion 5, so that the control board 4 has a slight amount of front and rear D and left and right C with respect to the slit vertical groove 3. In this state, the mounting screw 10 is passed through the recess 7 of the mounting piece 8 and fastened to the screw hole 9. Thereby, even if the concave portion 7 is displaced in the front / rear direction D / left / right C with respect to the screw hole portion 9, the positional displacement can be corrected by the movement of the control board 4 in the front / rear direction D / left / right C. Therefore, the gaps G1 and G2 between the slit vertical groove 3 and the insertion portion 5 can be used to absorb the front-rear D and left-right C errors between the screw hole portion 9 and the recess portion 7, and therefore the control board 4 An excessive tightening force is not applied, and the control board 4 can be securely fixed while effectively preventing the distortion of the control board 4.

  Moreover, by occupying the control board 4 vertically, the area occupied by the control board 4 in the main body 2 can be reduced. Therefore, the control board 4 does not become a harmful part as viewed from other parts, and the hot water washing toilet seat 1 The assemblability of is very good.

  Further, in this example, the control board 4 can be fixed simply and with a constant strength by the pair of left and right slit vertical grooves 3 of the main body 2 and the two mounting screws 10. Compared with the case where the conventional four places are screwed, the number of screwing places can be reduced and the assembly efficiency can be further improved.

  Further, in this example, since the slit vertical groove 3 is formed in a substantially V-shaped groove shape, when the insertion portion 5 is inserted into the slit vertical groove 3, the movement of the lower half of the control substrate 4 in the front-rear direction D is slit. Since the fixing screw 10 only needs to restrain the movement of the upper half of the control board 4 because it is stopped by the lower part of the vertical groove 3, the number of restraining parts of the control board 4 by the attaching screw 10 can be reduced. . Accordingly, the present invention is not limited to the case where the left and right two portions of the control board 4 are restrained by the mounting screws 10 as in this example, and one mounting screw 10 is possible. In this case, the number of mounting pieces 8 protruding from the control board 4 can be reduced by one, and the configuration of the control board 4 can be further simplified.

  In this example, the hot water tank 13 is arranged close to the front side in the main body 2, and the control board 4 is arranged vertically at the rear E of the hot water tank 13. The heat dissipation efficiency of the control board 4 can be improved, and water can be scattered on the control board 4 due to water leakage or dew condensation from the connection portion of the water supply hose discharged from the hot water tank 13. Also disappear. Even if water is scattered on the control board 4, it is possible to prevent water from quickly flowing down from the upper surface of the vertically placed control board 4 and storing it on the control board 4. That is, the vertical placement of the control board 4 makes it difficult for moisture and dust to adhere to the control board 4, thereby further enhancing the waterproof / heat dissipation effect of the control board 4.
