[0002]

2. Description of the Related Art FIG. 8 is a partially cutaway sectional view showing a conventional bath remote controller mounted on a wall surface. A rectangular box-shaped box main body (10) consisting of a synthetic resin bottom half (12) and an upper half (11) covering the open part of the box has a switch (22) and a hidden switch (23). An electronic board (51) including parts is housed, and a decorative cover (30) is externally fitted on the upper half body (11), and the box main body (10) and the decorative cover (30) are used for remote control. Case (1) is constructed.

The decorative cover (30) has an operation opening (330) which is opened and closed by an opening / closing lid (33), and the operation opening (330) is mainly formed in the box body (10). Portions of through holes (98) (98), which are switch operating portions formed at corresponding positions, are covered with a flexible sheet (29). The flexible sheet (2
When the through holes (98) and (98) of 9) are pressed and deformed, the hidden switches (23) and (23) are turned on and off via the switch pressing shafts (239) and (239). Also, on the surface of the makeup cover (30),
The operation buttons (13) (13) for operating the switches (22) (22) provided in the box main body (10) are exposed.

The bottom wall (121) of the bottom half body (12) forming the box main body (10) is provided with a projecting cylinder (124) protruding inside the box main body (10) and A wall penetrating pipe (48) is screwed into the cylinder (124).
A lead wire (64) connected to the electronic substrate (51) is inserted through the (48). An annular rubber plate (96) is attached to the outer surface of the bottom wall (121) of the bottom half body (12).

Next, the work of disposing the bath remote controller on the wall surface of the bathroom will be described. Insert the wall penetrating pipe (48) into the wall hole (82) penetrating the wall (81) of the bathroom (B), and attach the fixing nut (83) to the outside end of the bathroom of the wall penetrating pipe (48). It is screwed, so that the fixing nut (83) and the remote control case
Hold the wall (81) with (1). Then, the remote control case (1) is attached to the wall (81) with a gap (95) secured between the wall (81) and the remote control case (1).

[0006]

However, in the above-mentioned conventional apparatus, when the fixing nut (83) is screwed onto the outer end of the bathroom of the wall penetrating pipe (48) and is tightened, the tightening force is controlled by the remote controller. Since it acts centrally on the center of the bottom half (12) of the case (1), it creates a gap between the bottom half (12) and the wall (81).
The bottom half body (12) easily bends in the direction of narrowing (95). Therefore, in the above-mentioned conventional one, it is necessary to increase the strength of the bottom half body (12) in order to prevent the flexure, which causes a problem that the entire remote control case (1) becomes thick. It was

The present invention has been made in view of the above-mentioned point. "The remote control case (1) which accommodates electronic parts inside and is provided with a switch operation part is a wall penetrating pipe that penetrates a wall of a bathroom. A remote controller for a bath, which is fixed to a bathroom wall surface, in which a lead wire electrically connected to the electronic component penetrates a constituent wall on the bathroom wall surface side of the remote control case and is drawn out of the bathroom from the wall penetrating pipe. ], Even if the remote control case (1) is made thin overall, it is sufficient that the constituent wall on the wall (81) side of the remote control case (1) does not deform as the fixing nut (83) is tightened. The task is to ensure sufficient strength. <1>

[0008]

Means for Solving the Problems The technical means of the present invention for solving the above-mentioned problems are as follows: "A metal base plate externally fitted and fixed to an end portion of the wall-penetrating pipe inside the bathroom and the wall-penetrating pipe. The wall is sandwiched by a fastening member screwed to the outer end of the bathroom, the remote control case is attached to the metal substrate, and the lead wire penetrating portion of the remote control case is surrounded. A first annular packing interposed in an airtight state between the remote control case and the metal substrate, and the metal substrate and the bathroom so as to surround a mounting portion of the wall penetrating pipe in the metal substrate. A second annular packing interposed between the wall surfaces in an airtight manner and a part of the remote control case, which is surrounded by the first annular packing, communicates with the inside and outside of the remote control case and does not allow water to pass therethrough. ,Sky And a ventilation hole closed with a ventilation sheet that allows water vapor to pass therethrough, and the end portion of the wall-penetrating pipe on the side of the metal substrate is open in the space surrounded by the first annular packing. " is there. The “air” that the ventilation sheet passes through means dry air (air containing no water vapor) (hereinafter the same).

According to the above technical means, when the fastening member is screwed to the outer end of the bathroom of the wall penetrating pipe and is fastened, as in the above-mentioned conventional one, the fastening force is increased. Is transmitted to the metallic substrate externally fitted and fixed to the inner end of the bathroom, whereby the clamping force is received by the metallic substrate.

[0010]

Further, in the above technical means, the first annular packing, which is interposed between the remote control case and the metal substrate in an airtight state, surrounds the lead-through portion of the remote control case. At the same time, the inside of the surrounding space and the inside of the remote control case are connected to each other through a ventilation hole formed in a wall forming the remote control case so as to allow ventilation. or,
An end portion of the wall penetrating pipe on the side of the metal substrate is open in the space surrounded by the first annular packing. As a result, the inside of the remote control case and the wall penetrating pipe are connected by a continuous ventilation path in the order of the vent hole formed in the wall of the remote control case, the first annular packing, and the inside of the wall penetrating pipe. The ventilation hole is closed by a ventilation sheet. Therefore, when the air in the remote control case expands due to the temperature change in the bathroom, the expanded air in the remote control case permeates the ventilation sheet, passes through the ventilation path through the wall penetrating pipe, and the outside of the bathroom. Is released from the open end of the bathroom. On the contrary, when the temperature in the bathroom drops and the air in the remote control case contracts, the outside air outside the bathroom flows through the ventilation passage to the remote control case side, which causes the pressure in the remote control case. The drop is prevented. Therefore, the remote control case does not deform such that the remote control case slightly expands or contracts due to the temperature change in the bathroom.

<2> The invention of item 2 is a ventilation sheet that is impermeable to water and water vapor in place of the "gas and air and water vapor transmission sheet that is impermeable to water" which is a feature of the invention of item 1 above. Is adopted. That is, the technical means of the invention of item 2 is "a metal substrate externally fitted and fixed to an end portion of the wall penetrating pipe inside the bathroom, and a fastening member screwed to an outer end portion of the wall penetrating pipe outside the bathroom. The remote control case is attached to the metal substrate, and the wall is sandwiched between the remote control case and the metal substrate so as to surround the lead wire penetrating portion of the remote control case. A first annular packing that is interposed in a state, and a first annular packing that is interposed in an airtight state between the metal substrate and the bathroom wall surface so as to surround the mounting portion of the wall penetrating pipe in the metal substrate. 2 an annular packing, and a vent hole that connects a part of the remote control case that is surrounded by the first annular packing to the inside and outside of the remote control case and is closed by a ventilation sheet that is impermeable to water and water vapor. And Bei, an end of the metallic substrate side of the through-wall pipe is obtained by the open are "that in a space surrounded by said first annular packing.
In this device, as in the case of the above item 1, the air in the remote control case flows through the ventilation sheet as the temperature in the bathroom changes. Therefore, when the air in the remote control case expands due to the temperature change in the bathroom, the expanded air in the remote control case permeates the ventilation sheet, passes through the ventilation path through the wall penetrating pipe, and the outside of the bathroom. Is released from the open end of the bathroom. Conversely, if the temperature in the bathroom drops and the air in the remote control case contracts,
The outside air outside the bathroom flows through the ventilation path to the remote control case side, thereby preventing a pressure drop in the remote control case. Therefore, the remote control case does not deform such that the remote control case slightly expands or contracts due to the temperature change in the bathroom.

<3> In the above item 1 or 2, “the first annular packing is attached and fixed to the surface of the remote control case on the side of the metal substrate, and the remote control case is With respect to the box main body (10) and a box main body (10) for accommodating the electronic component, and a screw insertion hole for inserting a coupling screw that is screwed into a screw hole formed in the metal substrate, penetrates the front and back sides of the box main body (10). In the case of “having a decorative cover (30) fitted from the opposite side of the metal substrate”, the remote control case can be mounted and fixed on the wall surface of the unit bath by removing the remote control case from the metal substrate. That is, to dispose and fix the remote control case on the wall board of the unit bath, first, the remote control case is removed from the metal substrate.

Next, a screw hole is formed in the wall board of the unit bus, and a screw hole through which a screw insertion hole penetrating through the box main body (10) of the remote control case is stacked and a lead hole is inserted. The lead wire drawn from the outside is led out of the bathroom through the wiring hole. Then, a fixing screw is screwed into the screw hole of the wall plate of the unit bath from the screw insertion hole penetrating the box main body (10) of the remote control case to the front and back, and thereby, the box main body ( 10) Install.

Then, with the first annular packing arranged on the back surface of the box main body (10) interposed between the wall plate of the unit bath and the box main body (10), the box main body (10) is It is arranged and fixed to the wall plate of the unit bath. After that, when the decorative cover (30) is externally fitted to the front part of the box body (10), the work of disposing the remote control case on the wall plate of the unit bath is completed. <4> The metal substrate may be externally fitted and fixed directly to the end of the wall-penetrating pipe inside the bathroom, but via a fixing sleeve made of synthetic resin integrally formed with the metal substrate. It is also possible to indirectly fix the metal substrate to the wall penetrating pipe. That is, in the above items 1 to 3, "a fixing sleeve made of synthetic resin integrally formed with the metal substrate in a state of being inserted into a through hole formed in the central portion of the metal substrate is provided. At the same time, the metal sleeve is indirectly externally fitted and fixed to the wall penetrating pipe via the fixing sleeve by screwing the fixing sleeve to the end portion of the wall penetrating pipe inside the bathroom. A configuration can also be adopted.

The present invention has the following unique effects. Since the tightening force of the tightening member screwed onto the outer end of the wall-penetrating pipe in the bathroom is received by the metal substrate, the tightening force is received by the remote control case, which is different from the above-mentioned conventional remote control case. However, there is no concern about deformation due to the above tightening force. That is, even if the remote control case is made thin, sufficient strength against the tightening force can be secured. Further, as described above, the remote control case does not deform such that the remote control case slightly expands or contracts due to the temperature change in the bathroom. In the invention of item 1, the ventilation sheet that closes the ventilation holes does not allow water to pass through, but allows air and water vapor to pass through. Therefore, when water vapor enters the remote control case, the water vapor is discharged to the outside of the bathroom through the ventilation sheet. To be done. Therefore, no water vapor will be trapped inside the remote control case. In the invention of paragraph 2, since the ventilation sheet that closes the ventilation hole does not allow water and water vapor to pass therethrough, even if rainwater enters the wall penetrating pipe from outside the bathroom, this is blocked by the non-permeable ventilation sheet, and the remote control is used. There is no inconvenience to enter the case. That is, the electronic parts and the like in the remote control case are not exposed to the rainwater. According to the third aspect of the invention, if the remote control case is removed from the metal board, it can be fixedly mounted on the wall surface of the unit bath.
