Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sanitary washing apparatus, and more particularly to an improvement in a mounting structure in a case of a control board provided with a switch for controlling at least one of hot water washing, hot air heating, and a heated toilet seat.
[0002]
[Prior art]
For example, in the sanitary washing device disclosed in Japanese Utility Model Publication No. 3-42149, a control board on which a switch for controlling at least one of hot water washing, hot air heating, and a heating toilet seat is disposed is provided in the case. The spring is supported from below and is urged from above by a protrusion formed on the cover covering the upper opening of the case. Thus, the control board is elastically supported at a predetermined height position in the case. Each switch is opened and closed by an operation from the cover side.
[0003]
[Problems to be solved by the invention]
However, since the control board itself is formed to be relatively thin, in the above-described support structure, the control board is caused by the urging force of the spring in the mounted state and the pressing force applied to the control board during each switch operation. Therefore, there is a problem that the operational feeling of the switch is deteriorated.
[0004]
Therefore, this invention makes it the technical subject to provide the sanitary washing apparatus which does not have such a malfunction.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the technical means (first technical means) taken in claim 1 has a pair of support pins inside, is arranged close to the toilet bowl, and has an opening above it. A formed case, a fixing member housed in the case and having a mounting hole with respect to the case, an elastic body supported by the support pin and biasing the fixing member upward, and the elastic body A sanitary washing apparatus comprising: a cover body that presses the fixing member downward against the urging force of the battery; and a control board that is provided with a plurality of switches operated from the cover body side and is mounted on the fixing member The tip of the support pin is wider than the hole, and the fixing member can be temporarily fixed by the support pin having the wider width .
[0006]
In order to solve the above-described problem, the technical means (second technical means) taken in claim 2 is characterized in that the fixing member has protrusions at both ends contacting the inner surface of the cover body, and the protrusions are That is, the structure is formed above the elastic body .
Further, the fixing member is configured to be temporarily fixed by snap fitting with the support pin.
[0007]
[Action and effect]
In the first technical means described above, the control board is mounted on the fixed member , and the rigidity is improved as a whole. Therefore, even if the urging force by the elastic body or the force of the switch operation is applied, the control board is There is no deformation and the above-mentioned problems are not caused.
[0008]
In this case, the fixing member has protrusions that contact the inner surface of the cover body at both ends, and the protrusions are formed above the elastic body. Therefore, before attaching the cover body to the opening of the case, The fixing member jumps out by the reaction force can be temporarily fixed by the support member, and the assembling property can be stabilized.
Further, the fixing member can be temporarily fixed by snap fitting with the support pin.

DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described with reference to the accompanying drawings.
[0010]
In FIG. 1, the sanitary washing device includes a case 10 that is disposed in the vicinity of a toilet (not shown). An opening 12 is formed at the upper side of the case 10, and the opening 12 is closed by a cover body 14.
[0011]
Inside the case 10, a boss portion 16 and a boss portion 18 of the hot water tank 70 are integrally formed. The boss portion 16 (18) is supported by a support pin 24 (26) by a screw 20 (22). ) Is fixed. Thus, the support pin 24 (26) includes a base portion 24a (26a) positioned on the boss portion 16 (18) side and a shaft portion 24b (26b) in which a hook portion is formed at the tip and a cross slit is formed from the tip. ).
[0012]
The shaft 24 b (26 b) of the support pin 24 (26) is inserted through the hole 30 a (one end 30 b) at one end of the fixing member 30, and one end (the other end) of the fixing member 30. ) And a base portion 24a (26a) of the support pin 24 (26), a spring 32 (34) is stretched, and both the springs 32 and 34 are connected to one end and the other end of the fixing member 30. The end is biased upward. Further, the two protrusions 14 a formed on the fixing member 30 press the inner surface of the cover body 14. As a result, the fixing member 30 is sandwiched between the springs 32 and 34 and the inner surface of the cover body 14 and is held in a fixed position. Note that the protrusion 14 a may be formed on the cover body 14 and the fixing member 30 may be pressed.
[0013]
The fixing member 30 has a recess 38 formed in the center, and a control board 40 is disposed inside the recess 38. Thus, the switches 42, 43, 44, 45 and 46 are mounted on the control board 40, and these are well known by pressing the corresponding shafts 52, 53, 54 and 56 from above. It can be opened and closed. The shafts 52, 53, 54, 55 and 56 pass through the cover body 14. The upper end surfaces of the shafts 52, 53, 54, 55 and 56 are engaged with the sheet 62 covered on the cover body 14, and the type of the switch is printed on the sheet surface of this portion. And if any switch is pushed, control of warm water washing, warm air heating, toilet seat heating, etc. will be governed.
[0014]
After the control board 40 is mounted in the recess 38 of the fixing member 30, the resin 60 is poured into the recess 38 (so-called potting), and the electronic elements on the control board 40 are released from moisture or toilet cleaning chemicals. Corrosion is prevented by
In the figure, reference numeral 70 denotes a hot water tank, which is connected to a water pipe (not shown) via a flow valve 72 and a main valve 74. The flow valve 72 is operated by operating a dial 76 located on the cover body 14.
