The device storage case and its manufacturing method according to the present disclosure, and the embodiment of the toilet seat device using the device storage case are not limited to the following embodiments, and are not deviated from the technical idea of the present disclosure. , Various changes are possible.

(Embodiment)
The device storage case and the manufacturing method thereof, and the toilet seat device using the device storage case according to the present embodiment will be described with reference to FIGS. 1 to 7.

(1) Toilet bowl device As shown in FIG. 1, the equipment storage case 1 according to the present embodiment is a part of the toilet seat device 4. The toilet seat device 4 constitutes a part of the toilet bowl device 5. Although not particularly shown, the toilet bowl device 5 includes a bowl portion. The bowl portion is made of resin. An equipment storage space is formed behind the bowl portion. A movable trap device is stored in the device storage space. The toilet device 5 includes a cover 51, and the bowl portion and the equipment storage space are covered by the cover 51 around the front, back, left, and right. The toilet seat device 4 is provided on the upper part of the rear part of the bowl portion.

(2) Toilet seat device The toilet seat device 4 has an equipment storage case 1, a toilet seat, and a toilet lid 43. The toilet seat is attached to the device storage case 1 so that the state of being placed on the rim at the upper end of the bowl portion and the state of standing up can be selected. The toilet lid 43 is attached to the device storage case 1 so that the state of being placed on the toilet seat and the state of standing up can be selected.

(3) Equipment storage case As shown in FIG. 2, the equipment storage case 1 can be opened and closed so as to cover the case main body 13 that covers the internal space and the case top plate 131 of the case main bodies 13. A case cover 14 is provided. Devices such as a substrate 40 (see FIG. 3), an operation unit 44, a display unit 45, a remote control transmission / reception unit 46, a detergent tank, and a battery case are housed in the case body 13.

The device storage case 1 is made of resin. In particular, the device storage case 1 is preferably made of ABS resin, which does not easily transmit light.

(3.1) Case Cover The case cover 14 has a light transmitting portion 2 and a light impervious transmitting portion 3. The light transmitting portion 2 is formed in a part of the device storage case 1 and has a thickness within a predetermined range. On the other hand, the light-difficult-transmitting portion 3 is formed adjacent to the light-transmitting portion 2 and has a thickness larger than a predetermined range. That is, the light transmitting portion 2 is a thin-walled portion formed on the case cover 14.

As shown in FIG. 3, the light transmitting portion 2 is a portion that transmits light emitted by a light source 41 composed of an LED (Light Emitting Diode) housed in a case body 13. The upper limit of the thickness range of the light transmitting portion 2 is preferably 0.35 mm that transmits the light emitted by the LED, but may be 0.4 mm or 0.5 mm. As the thickness of the light transmitting portion 2 increases, it becomes more difficult for light to pass through. Therefore, it is preferable that the upper limit of the thickness range of the light transmitting portion 2 is smaller.

Further, the lower limit of the thickness range of the light transmitting portion 2 is, for example, 0.3 mm, but may be 0.2 mm or 0.1 mm. As the thickness of the light transmitting portion 2 increases, the light transmitting portion 2 is less likely to be damaged. Therefore, it is preferable that the lower limit of the thickness range of the light transmitting portion 2 is larger. In the present embodiment, the thickness of the light transmitting portion 2 is 0.35 mm.

The light-difficult-transmitting portion 3 has a thickness larger than the upper limit of the thickness range of the light-transmitting portion 2. In the present embodiment, the thickness of the light-difficult-transmitting portion 3 is 2.5 mm. The thickness of the case cover 14 is 2.5 mm in most parts other than the light transmitting portion 2, but in the portion adjacent to the light transmitting portion 2, the thickness is from 2.5 mm to the thickness of the light transmitting portion 2. It continuously changes to a certain 0.35 mm. Since the device storage case 1 is made of ABS resin, which does not easily transmit light, the light-impermeable portion 3 can be easily configured.

(3.2) Display unit The display unit 45 includes a light source 41, a light guide member 42, a display sheet 47, and a light transmission unit 2. The light source 41 is mounted on the substrate 40 and is provided at a position corresponding to the light transmitting portion 2. The light source 41 and the substrate 40 are provided inside the case top plate 131.

The light guide member 42 is arranged between the inner surface 22 of the light transmitting portion 2 and the light source 41. The light guide member 42 is arranged in a hole formed in the case top plate 131. The light guide member 42 is inserted into a hole formed in the case top plate 131 from the outside of the case top plate 131, and the portion not inserted into the hole and the outer surface of the case top plate 131 are in close contact with each other by double-sided tape (not shown). Will be done. This makes it difficult for water to enter the case body 13 from the outer surface side of the case top plate 131. The display sheet 47 is attached to a portion other than the portion corresponding to the hole formed in the case top plate 131 on the outer surface of the light guide member 42.

The outer surface 21 of the light transmitting portion 2 is recessed inward with respect to the outer surface 31 of the light transmissing portion 3, and the recess 111 is formed on the outer surface 11 of the device storage case 1. That is, the outer surface 21 of the light transmitting portion 2 is a recess 111 that is recessed inward with respect to the outer surface 31 of the light transmissing portion 3 around the light transmitting portion 2. In this way, the outer surface 21 of the light transmitting portion 2 formed in the device storage case 1 becomes the recess 111, so that when the outer surface 11 of the device storage case 1 is wiped and cleaned, it protrudes from the surrounding outer surface 11. Since the cloth does not hit the light transmitting portion 2 and is difficult to wipe, the careability is improved. Further, when cleaning by wiping, it is unlikely that the protruding light transmitting portion 2 is pushed and the light transmitting portion 2 is damaged.

The outer surface 21 of the light transmitting portion 2 is a concave surface forming a part of a spherical surface. This makes it easy to form a uniform concave surface on the outer surface 21 of the light transmitting portion 2.

The recess 111 formed on the outer surface 11 of the device storage case 1 preferably has a diameter of 7 mm or less. When the diameter of the recess 111 is 7 mm or less, it is difficult for a general adult finger to enter the recess 111, and even if the finger enters the recess 111, it is difficult to push the outer surface 21 of the light transmitting portion 2 with a strong force. Therefore, the light transmitting portion 2 formed by the thin-walled portion is less likely to be damaged.

The inner surface 22 of the light transmitting portion 2 is recessed outward with respect to the inner surface 32 of the light transmissing portion 3, and the recess 121 is formed on the inner surface 12 of the device storage case 1. As a result, it becomes easy to form the light transmitting portion 2 having a thickness of 0.35 mm adjacent to the light transmitting portion 3 having a thickness of 2.5 mm. Further explaining, the light transmitting portion 2 which is considerably smaller than the thickness (2.5 mm) of the light transmissing portion 3 without making the depth of the recess 111 formed on the outer surface 11 of the device storage case 1 extremely deep. A thickness (0.35 mm) can be achieved.

The device storage case 1 has a convex surface on the inner surface 22 of the light transmitting portion 2, which projects inward and the surface forms a part of a spherical surface. By locating the convex surface on the inner surface 22 so as to correspond to the concave surface of the outer surface 21, it becomes easy to make the thickness of the light transmitting portion 2 which is the thin-walled portion uniform.

(4) Equipment Storage Case Manufacturing Method The equipment storage case manufacturing method is a method of manufacturing a resin equipment storage case 1 for the toilet seat device 4 by using a resin molding device having a mold 6.
