Description

[Detailed description of the invention] [Purpose of the invention] (Industrial field of application) This invention relates to an electrical control device for a toilet bowl, and is particularly used to improve the insulation of the electrical control device in a toilet bowl equipped with a device for washing private parts of the human body. .

(Prior Art) Conventionally, a switch volume disposed on the main body of an electric control device has been directly fixed to a metal bracket disposed on the toilet main body without intervening other members. This electrical control device body also has an IC circuit and other electrical regulators fixed to it. Additionally, a ground wire is connected to the metal bracket to prevent electrical leakage.

(The problem that the invention aims to solve) However, if the high voltage impulse generated during a lightning strike is applied between the power supply and the ground, it will break down the insulation of the switch volume and will be transmitted to the IC circuit. There was a risk of destroying the circuit.

Therefore, the purpose of this invention is to protect the IC circuit by ensuring insulation between the switch volume and the metal bracket.

[Structure of the idea]

(Means for solving the problem) In order to solve the problem, the present invention uses the following technical means. That is, a metal bracket attached to the toilet bowl, a hole formed in the metal bracket, an outer insulating part provided on the outer surface of the hole, and an insulating part provided on the inner surface of the hole. An inner insulating part that is in close contact with an outer insulating part, a mounting hole that penetrates the outer insulating part and the inner insulating part, and a switch volume that protrudes from the mounting hole and is fitted into the mounting hole, and is mounted on the inside of the metal bracket. It has an electrical control device main body that is mounted and connected to an IC circuit, and the inner insulating part has a hanging portion that extends inside the metal bracket and covers up to the lower end of the main body of the electrical control device. This is an electric control device for a toilet bowl, which is characterized by:

(Function) In the present invention, since the outer insulator and the inner insulator are interposed between the metal bracket and the main body of the electric control device,
The electrical control parts are completely electrically isolated from the metal bracket.

(Embodiment) FIG. 1 shows an embodiment of the present invention, in which 1 is a metal bracket, and 2 is a ground member whose one end is fixed to the metal bracket 1 with a screw 3. A hole 1a is bored in the metal bracket 1, and the outer insulating portion 5 is connected to the hole 1a by a convex portion 5a projecting downward.
Similarly, the inner insulating portion 4 is fitted into the hole 1a with a convex portion 4a projecting upward from the inner surface. Both surfaces of the upper surface of the convex portion 4a and the lower surface of the convex portion 5a are in close contact with each other, and a mounting hole 14 penetrating through both is bored approximately in the center. The inner insulating part 4 has a hanging part 4b on the outer periphery that covers up to the lower end of the terminal 12 of the electrical control component main body 8, which will be described later.

The electrical control component main body 8 is provided with a terminal 13 connected to an IC circuit 15 and a terminal 12 protruding from below and connected to other electrical components. Further, a switch volume 6 is attached to one side of the electric control device main body 8 via a locking member 7 and a fixing female screw 6a.

This switch volume 6 is inserted into a mounting hole 14 made in the outer insulator 5 and inner insulator 4, and by tightening this switch volume 6 with a nut 9, the electric control device main body 8 is attached to the metal bracket 1. Fixed. At the same time, the upper insulator 5 and the lower insulator 4 are brought into close contact with each other, and the outer peripheries of the respective protrusions 4a and 5a sandwich the bracket 1.

FIG. 2 shows an overall view of this embodiment, and shows a regulator 1 which is adjacent to the electrical control device main body 8 and is another electrical component.
A diagram in which 0 is arranged is shown. In this way, the hanging part 4b of the inner insulating part 4 is connected to the ground of the capillary tube 11 of another electric regulator (the illustrated example is a liquid expansion type temperature regulator) 10 provided around the control device 8. This prevents the non-charged metal parts from coming into contact with the terminal parts 12, 13, etc. of the control device.

In conventional devices, non-charged metal parts were fixed with a binder or the like to eliminate the risk of contact with terminals or the like.

Additionally, toilet bowls are sometimes installed in bathrooms, making them susceptible to water from outside. In this embodiment, even if it is exposed to splashing water, the electric control device main body 8
is covered, so there is no risk of this water entering the inside of the main unit. In particular, when the main body 8 is microcurrent controlled, even a small amount of water often interferes with the function, but this embodiment eliminates such problems.

[Effect of idea]

According to the present invention, the main body of the electrical control device, along with the switch volume, is completely insulated from the metal bracket by the outer and inner insulators, so high voltage will not be applied even during lightning strikes, and the IC circuit will not be exposed to high voltage. can be reliably protected.

In addition, since gases such as ammonia generated in the toilet room corrode the metal bracket, there is a risk that the corrosive powder may adhere from the sides of the electrical control device body, but in this invention, the hanging part of the inner insulation part Since the lower end of the device body is covered to protect the electrical control device body and the terminals protruding from the device body, attachment of such corrosive powder can be prevented.

Furthermore, since the hanging portion of the inner insulating portion is interposed between the electrical control device main body and other adjacent electrical components, it is safe because it does not come into contact with other electrical components.
