Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Use The present invention relates to a structure for preventing a potting liquid from entering a timer display section of an operation panel section.

(B) Prior art The applicant has previously filed an application for a structure of an operation panel of a bubble-generating bathtub described in Japanese Utility Model Application No. 2-6381.

Such an operation panel section structure is characterized in that a thermosetting potting liquid such as urethane resin or epoxy resin is filled in the operation panel section, and an electric circuit section disposed in the operation panel section is embedded in the potting liquid. It is assumed that.

With this structure, complete waterproofness can be ensured even when the operation panel is attached to the edge of the bathtub body where the bath water is always applied, so that the insulation of the electric circuit can be kept good and the operation can be maintained. The strength of the panel can be increased.

In addition, the electric circuit portion disposed in the operation panel portion has a timer display portion, and the timer display portion is formed of a transparent resin cap on the upper portion of a display portion main body that displays time, blow time, etc. The upper surface of the display window is exposed from an opening formed on the upper surface of the case of the operation panel so that the display main body can be visually recognized through the display window.

(C) Problems to be Solved by the Invention However, the above-mentioned operation panel structure still has the following problems.

That is, when the potting liquid is filled in the operation panel section, the potting liquid enters the display window from the fitting portion between the display section main body and the display window, and the liquid crystal display time is displayed on the display section main body by the potting liquid. And the like cannot be visually recognized from the outside through the display window.

(D) Means for Solving the Problems Therefore, in the present invention, an electric circuit section having a timer display section is provided in a panel section case, and the timer display section is composed of a display section main body and the display section main body. And a cap-shaped display window fitted to the upper part of the display unit. The display window is exposed from an opening opened in the panel case, so that the display unit main body can be visually recognized from the outside through the display window, and the panel unit is formed. An operation panel section in which a thermosetting potting liquid such as urethane resin or epoxy resin is filled in a case, and an electric circuit section is embedded in the potting liquid, and a fitting section between the display section main body and the display window. It is an object of the present invention to provide a potting liquid intrusion prevention structure of a timer display section in an operation panel section, wherein a tape for preventing intrusion of a potting liquid is adhered to an outer peripheral surface.

As the independent foam sheet, for example, chloroprene or the like is used. There are synthetic rubber, polyethylene resin, polypropylene resin, ether resin, and ester resin.

Also, fill and solidify the potting liquid (40) such as urethane resin or epoxy resin in the panel case (20).
By embedding the entire electric circuit section (21) in the potting liquid (40), the shock resistance and vibration resistance of the entire electric circuit section (21) are improved, and waterproof and insulating properties are ensured to prevent malfunction and This prevents the inability to operate.

In addition, the potting solution (4
Since (0) is filled and solidified, the strength of the case (20) can be increased.

Also, since the potting liquid (40) is filled in the panel case (20), air hardly stays. Therefore, the infrared receiving section (9) and the timer display section (30) are not filled. Since the volume of air with respect to the internal surface area can be minimized, it becomes difficult to cloudy, and the use of a clouding-stopping agent or the like has a further clouding effect.

The infrared receiving section (9) provided on the left side of the operation panel section (6) is provided with the remote controller (130).
When a predetermined code signal corresponding to each switch is transmitted from an infrared transmitter provided in the remote controller (130) based on a serial code transmission signal set in advance by operating each switch provided in Detects and outputs the detection signal to the input interface (a) of the control unit (C).
Then, a desired driving device is driven based on the driving program read from the memory (m).

As shown in FIG. 7, the infrared receiving section (9) provided on the operation panel section (6) is provided in a hemispherical shape so as to protrude from the surface of the operation panel section. As shown in FIG. 8, the hemispherical infrared receiving section (9) has an inner water surface of the bathtub body (1) because the surface of (1) is formed so as to have a downward slope toward the inside of the bathtub as shown in FIG. The infrared signal can be received from almost the entire area of the bathtub, and outside the bathtub body (1), the infrared signal can be received over the entire area of the bathroom from above the height of the bathtub body (1).

In such a configuration, the gist of the present invention resides in a structure for preventing the intrusion of the potting liquid (40) into the timer display section (30). Hereinafter, referring to FIGS. 6, 7, and 9 to 11, explain.

That is, as shown in FIG. 6, the timer display section (30) is provided with a socket (3) connected to the board (50) for raising.
5) Connect the display unit (31) to the top,
A cap-shaped display window (32) is fitted on the upper part of 1), and the upper part of the display window (32) is fitted into the opening (25c) opened on the right side of the ceiling wall of the upper case (25). Let me.

The display unit body (31) displays the time, blow time, and the like on the liquid crystal display using a liquid crystal display.
As shown in the figure, raise the socket (35)
By being positioned close to the opening (25c), visibility from the outside is improved.

The display window (32) is formed integrally with a window body (32b) that can be fitted into the opening (25c) at the top of a fitting body (32a) that can be fitted over the display unit body (31). The display window (32) is made of transparent acrylic resin, ABS resin, or polysulfone.

The tape (34) is a self-fusing rubber tape such as butyl rubber or silicone, and seals the fitting portion between the fitting body (32a) and the display unit body (31) to form the window body (32).
b) The potting liquid (40) is prevented from entering the inside.

In this way, good visibility of the display unit main body (31) from the outside through the display window (32) is ensured.

Also, in places where the window body (32b) is small on the upper surface of the display unit body (31), the side surface inside the display window (32) may obstruct the aesthetic appearance of the inside of the body or the potting liquid (40). Since a black tape cannot be seen, the potting liquid (40) or the like can be made invisible from the outside through the display window (34) by using a black tape as the tape (34).

At this time, the upper edge of the tape (34) is brought as close as possible to the back surface of the upper case (25), so that the above-mentioned visual aesthetics can be surely improved.
