Description

  The present invention relates to a remote controller that is installed in a place with high humidity such as a bathroom and operates a water heater outside the bathroom.

  2. Description of the Related Art Conventionally, in bathroom equipment with a built-in speaker, at least a first hole for sound passage is provided in a sealed main body case having a space for incorporating a speaker, and the first hole is made of water-resistant cone paper. The main body case is provided with a second hole portion, and the second hole portion is sealed with a diaphragm-like member that can be freely deformed according to a pressure difference applied to both surfaces thereof. A bathroom device is disclosed in which a speaker cone paper is deformed with a pressure difference smaller than a pressure difference that causes displacement due to a pressure difference applied to both sides thereof and has no air permeability (for example, a patent) Reference 1).

Japanese Patent Laid-Open No. 2002-354692

  However, according to the above-described conventional technique, the sealed main body case having a space for incorporating the speaker is provided with the first hole for sound passage, and the first hole is provided with water-resistant cone paper. The main body case is provided with a second hole portion, and the second hole portion is sealed with a diaphragm-like member that is freely deformed according to a pressure difference applied to both surfaces thereof.

  The speaker emits sound due to the vibration of the cone paper. This cone paper is a thin film that vibrates when an electric current is passed through the cone paper coil, and is weak against the pressure difference between the front and back sides. In the above prior art, the back side of the cone paper is sealed with a diaphragm-like member. Therefore, there is a problem that a pressure difference is generated between the front and back of the cone paper, and the sound may be crushed or the corn paper may be crushed.

  The present invention has been made in view of the above, and an object of the present invention is to obtain a remote controller in which no pressure difference is generated between the front and back of the cone paper of the waterproof speaker, and the sound is not crushed or the cone paper is not crushed. .

  In order to solve the above-described problems and achieve the object, the present invention includes a first chamber in which a display device is installed in a display window formed on an outer wall and an electronic circuit board is installed therein, and a partition wall. A second chamber in which a waterproof speaker is installed in a sound passage window formed on the outer wall, and an airtight pressure for closing the first hole provided in the partition wall. A housing having a buffer film and a second hole provided in an outer wall of the second chamber is provided.

  The remote controller according to the present invention produces an effect that no pressure difference is generated between the front and back of the cone paper of the waterproof speaker, and there is no possibility that the sound is crushed or the corn paper is crushed.

FIG. 1 is a perspective view showing a state in which a remote controller according to the present invention is installed on a bathroom wall. FIG. 2 is a longitudinal sectional view showing an embodiment of a remote controller according to the present invention. FIG. 3 is an enlarged view of a portion B in FIG. 2 showing a state where the pressure buffer film swells. FIG. 4 is an enlarged view of part B in FIG. 2 showing a state in which the pressure buffer film is deflated. FIG. 5 is an enlarged view of a portion C in FIG. 2 showing a state in which condensed water is drained. FIG. 6 is an enlarged view of a portion C in FIG. 2 showing a state where water from the outside is blocked.

  Embodiments of a remote controller according to the present invention will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment FIG. 1 is a perspective view showing a state in which a remote controller according to the present invention is installed on a wall of a bathroom, and FIG. 2 is a longitudinal sectional view showing an embodiment of the remote controller according to the present invention. 3 is an enlarged view of part B of FIG. 2 showing a state in which the pressure buffer film is expanded, FIG. 4 is an enlarged view of part B of FIG. 2 showing a state in which the pressure buffer film is deflated, and FIG. FIG. 6 is an enlarged view of part C of FIG. 2 showing a state in which condensed water is drained, and FIG. 6 is an enlarged view of part C of FIG. 2 showing a state of preventing water from entering from the outside.

  As shown in FIG. 1, a remote controller 90 according to the embodiment is installed on a wall 82 of a bathroom near a bathtub 81, and operates a push button switch 21 so as to be installed outside the bathroom. Remotely control the hot water bath, chasing, adding hot water, etc.

  As shown in FIGS. 1 and 2, the components of the remote controller 90 are housed in an airtight rectangular housing 10. The casing 10 is formed in the first chamber 11 in which a display device 22 such as a liquid crystal panel is installed in the display window 17 formed in the outer surface wall 10a and the electronic circuit board 23 is installed in the inside, and in the outer surface wall 10a. The sound passage window 18 includes a second chamber 12 in which a waterproof speaker 24 is installed and is narrower than the first chamber 11.

  The first chamber 11 and the second chamber 12 are hermetically partitioned by a partition wall 13. A first hole 14 is provided in the partition wall 13. As shown in FIGS. 3 and 4, the first hole 14 is closed by an airtight pressure buffer film 15. The pressure buffer film 15 may be a non-stretchable synthetic resin film attached to the first hole 14 in a relaxed state, or a stretchable rubber film.

  The electronic circuit board 23 and the waterproof speaker 24 are connected by a wiring 25 penetrating the partition wall 13 in an airtight manner. As described above, the first chamber 11 has an airtight structure in which moisture from the outside does not enter.

  When the air in the first chamber 11 is warmed and expanded due to the heat generated by the electronic circuit board 23, the pressure buffer film 15 expands toward the second chamber 12 as shown in FIG. The pressure rise in the chamber 11 is buffered. When the remote controller 90 cools and the air in the first chamber 11 contracts and the pressure decreases, the pressure buffer film 15 contracts toward the first chamber 11 as shown in FIG.

  Since the pressure buffer film 15 is attached to the partition wall 13 inside the housing 10, there is no adverse effect on the external design of the remote controller 90. Further, since the pressure buffer film 15 cannot be touched from the outside, the pressure buffer film 15 is not damaged when the remote controller 90 is installed.

  As shown in FIGS. 2, 5, and 6, a second hole 16 is provided in the side outer wall 10 b at the bottom of the second chamber 12. Further, a water blocking wall 10 c is provided inside the second hole 16. As shown in FIG. 5, the second hole 16 discharges condensed water accumulated at the bottom of the second chamber 12.

  As shown in FIG. 6, the water blocking wall 10 c prevents the condensed water flowing down along the side outer wall 10 b of the housing 10 from entering the second chamber 12. The second chamber 12 has a structure in which a difference in atmospheric pressure from the outside does not occur due to the second hole 16.

  In the remote controller 90 of the embodiment, the waterproof speaker 24 is installed in the second chamber 12 having the same atmospheric pressure as the outside through the second hole 16. As the waterproof speaker 24, a speaker whose coil portion on the back of the cone paper is also waterproof is used. In the remote controller 90 of the embodiment, no pressure difference is generated between the front and back of the cone paper, and there is no possibility that the sound is crushed or the corn paper is crushed.

  In the remote controller 90 of the embodiment, the first chamber 11 in which the electronic circuit board 23 and the display device 22 that are susceptible to moisture and condensation are installed has an airtight structure that does not allow moisture from the outside to enter. A short circuit or disconnection of the electronic circuit board 23 and a display abnormality of the display device 22 can be prevented. Further, silicon caulking when the remote controller 90 is installed on the bathroom wall 82 is not necessary.

  As described above, the remote controller according to the present invention is useful for installing a bathroom.
