  However, in the bathroom acoustic device disclosed in Patent Document 1, an opening hole for a speaker device is formed on the ceiling surface, and the speaker device is attached to the ceiling surface by inserting the speaker device into the opening hole. For this reason, an opening hole for the speaker device must be provided on the side wall or ceiling of the bathroom separately from the opening hole for the bathroom air conditioner. As a result, there is a problem that the number of work steps increases and the burden on the worker increases.

  In addition, when the speaker device is directly attached to the ceiling surface, the sound generated from the speaker device leaks to the back of the ceiling, which may cause a noise problem particularly in an apartment house such as an apartment. Furthermore, in Patent Document 2, a speaker is provided in a bathroom air conditioner, and the main unit box resonates due to the sound that comes out from the back surface of the speaker as the device becomes large, and the sound quality of the sound that comes out from the back surface of the speaker. May decrease.

  The present invention has been made in view of the above problems, and its purpose is to allow a speaker device to be easily installed without increasing the size of the bathroom air conditioner body, and to be output from the speaker device. An object of the present invention is to provide a bathroom air conditioner that prevents noise caused by the sound leaking to the back of the ceiling.

  The bathroom air conditioner of the present invention is a bathroom air conditioner body provided with a suction part for sucking air in the bathroom, and a blowout part for blowing air into the bathroom, and a surface exposed to the bathroom of the bathroom air conditioner body. A front panel for covering, and a speaker housing portion having a space for housing the speaker device, the speaker housing portion being attached to the outside of the bathroom air conditioner body or the front panel via a connecting means. It is characterized by this.

  In the present invention, the speaker device refers to either a single speaker or a complex in which an electronic device such as an amplifier is connected to the speaker.

  The connecting means connects the first flange provided in the bathroom air conditioner main body, the second flange provided in the speaker housing portion, and the first flange and the second flange to each other. And the speaker housing portion is in a state in which the second flange of the speaker housing portion is inserted in a gap between a ceiling surface to which the bathroom air conditioner main body is attached and the third flange. Connected to the first flange.

  Since the speaker housing portion in which the speaker device is housed is attached to the outside of the front panel via the connecting means, when the speaker device is installed in the bathroom, only the opening hole for the bathroom air conditioner is provided in the ceiling. There is no need to newly construct a separate opening for the speaker device on the ceiling.

  On the side surface portion of the housing constituting the speaker housing portion and the side surface portion of the front panel, there is a lead-out portion for pulling out a cable wire connected to the speaker device housed in the speaker housing portion to the front panel side. Each of the cable lines is formed, and the cable line is attached to the lead-out part via a sealing member. The speaker housing is sealed by this sealing member.

  A speaker device is attached to the ceiling panel via a casing constituting the speaker housing portion. For this reason, sound leakage of sounds such as music output from the speaker device is reduced. Thereby, sound leakage to the back surface of the ceiling panel can be prevented, and problems such as noise can be reliably avoided as compared with the case where the speaker device is directly attached to the ceiling panel. The effect is particularly great in apartment houses.

  According to the present invention, when the speaker device is installed in the bathroom, it is not necessary to newly construct an opening hole for wiring the speaker device in the ceiling surface. Therefore, in the installation work of the speaker device, the workability can be improved and the burden on the operator can be reduced as compared with the conventional case. Furthermore, sound quality reduction from the speaker can be prevented or suppressed without increasing the size of the bathroom air conditioner.

The speaker is drawn from the inside of the speaker housing portion 32 to the outside (inside the front panel 4) through the passage hole 106 formed in the side surface portion 12a of the front panel 4. At this time, the cable wire 30 is mounted in the extraction hole 33 and the passage hole 106 in a state of being covered with a sealing member 110 such as a rubber packing that is waterproof and moisture-proof. Thereby, the waterproofness (sealing property) inside the speaker accommodating part 32 is ensured.

  Further, the bathroom air conditioner main body 2 is configured such that the cable wire for the speaker 31 attached in the bathroom is connected to the main body case 28, as is apparent from FIGS. 4 (a) and 4 (b) showing the area A in FIG. The insertion holes 36 and 37 for laying through the inside and the space part 100 (refer FIG. 1) used as the area | region for laying this cable wire are provided.

  The space portion 100 is a space region surrounded by the inner peripheral surface 28b of the main body case 28 and the outer peripheral surface 23b of the fan case 23, and the fan suction port so as not to disturb the flow of air sucked in or out of the bathroom. A space region in which 20 a, the air outlet 20 b, and the outlet 20 c are not formed is set as the space portion 100. In this example, as shown in FIG. 1, an end region inside the apparatus main body in which an air passage between the outer peripheral surface 23 b of the fan case 23 and the inner peripheral surface 28 b of the main body case 28 is not formed is a space portion 100. Is set.

  As shown in FIG. 4A, the insertion hole 36 is formed in the upper surface portion of the main body case 28 constituting the space portion 100 in this example. As shown in FIG. 4B, the other insertion hole 37 is formed in the bottom surface portion of the fan case 23 constituting the space portion 100 in this example. These insertion holes 36 and 37 are formed in a shape corresponding to a cable line, a connector and a rubber packing, which will be described later, and are formed in a rectangular shape in plan view in this example (see FIG. 5). The shape of the insertion holes 36 and 37 is not limited to the illustrated rectangular shape as long as it is a shape capable of inserting a cable line or a connector. For example, a circular shape or the like may be used.

  As shown in FIGS. 4A and 5, a notch portion (step portion) 86 having a slightly larger diameter than the outer diameter of the insertion hole 36 is formed in the peripheral portion of the insertion hole 36 on the outer surface of the main body case 28. The The notch 86 functions as a recess for detachably mounting a seal lid 84 described later, which functions as a sealing member. On the other hand, on the inner surface side of the main body case 28 of the insertion hole 36a, a projecting portion 87 projecting downward is formed surrounding the periphery. The protruding portion 87 functions as a support region for securely fixing a connector 34a (described later) that is mounted and fixed in the insertion hole 36. As shown in FIG. 4B, similar notches 86 and protrusions 87 are also formed on the peripheral edge of the insertion hole 37 formed on the bottom surface side of the fan case 23.

  The bathroom air conditioner main body 2 includes a relay cable 10 laid in the space 100 as shown in FIG. The relay cable line 10 is an example of a cable line wired to the speaker 31 described above, such as a cable line of the speaker 31 attached to the ceiling surface in the bathroom and an amplifier installed on the ceiling behind the bathroom. It is a relay line laid in advance to connect the cable line to the interior of the bathroom air conditioner body 2. As will be described later, in this example, since the audio output output from the tuner or the like is reproduced in stereo using the two speakers 31, two relay cable lines 10 are laid correspondingly. As shown in FIGS. 4 (a) and 4 (b), one end for connecting the cable wire 30 of the speaker 31 and the cable wire 48 such as an amplifier is connected to each end of the two relay cable wires 10. The male connector 34a is attached to the other end, and the female connector 35a is attached to the other end.

  The male connector 34a of the relay cable 10 is mounted at a predetermined position of the insertion hole 36 via a support member 38 inserted between the hole peripheral surface of the insertion hole 36 and the outer peripheral surface of the male connector 34a. Fixed. Similarly, the female connector 35 a at the other end is also mounted and fixed at the position of the insertion hole 37 via the support member 38. As the support member, for example, an elastic material that is stretchable to fill these gaps, and a waterproof and moisture-proof material that prevents moisture in the bathroom from leaking out to the back of the ceiling is used. In this example, a waterproof and moisture-proof rubber packing 38 is used. Since air (humidity) sucked into the bathroom air conditioner body 2 from the bathroom can be prevented from leaking from the insertion holes 36 and 37 to the ceiling, generation of mold and the like can be suppressed. By fixing the male connector 34 a and the female connector 35 a at the positions of the insertion holes 36 and 37 with the rubber packing 38, the relay cable wire 10 can be installed (laid) in a predetermined position of the space portion 100 in advance.

  Next, a case where the cable line 30 of the speaker 31 and the cable line 48 of the amplifier are connected to each other via the relay cable line 10 laid in the space 100 of the bathroom air conditioner body 2 described above will be described. As shown in FIG. 4B, the male connector 30a attached to one end of the cable wire 30 connected to the speaker 31 is connected (attached) to the female connector 35a attached and fixed at a predetermined position of the insertion hole 37. ) As shown in FIG. 1 and FIG. 11 to be described later, the cable wire 30 connected to the speaker 31 is laid in a route along the lower surface of the fan case 23 avoiding the fan suction port 20a and the air outlet 20b, and is fixed not shown. It is preferable to fix the bent portion of the cable wire 30 to the fan case 23 with a member. Similarly, as shown in FIG. 4A, the female connector 48a attached to one end of the cable wire 48 connected to the amplifier is connected to the male connector 34a fixed to the position of the insertion hole 36. Thus, for example, the speaker 31 attached to the ceiling surface in the bathroom and the amplifier or the like installed on the back of the ceiling outside the bathroom are relayed in the bathroom air conditioner body 2 using the cable lines 30 and 48. It can be electrically connected via the cable line 10.

  Since the relay cable line 10 is always laid in the space 100 of the bathroom air conditioner body 2, the relay cable line is used even when the bathroom air conditioner body 2 that does not include the speaker 31 is used. 10 is never removed. Accordingly, when the relay cable wire 10 is not used, the connector-protecting seal lid 84 is formed in the notch 86 from the outside of the main body case 28 as shown in FIGS. 6 (a), 6 (b) and FIG. The outer surface side of the insertion holes 36 and 37 is covered by mounting. The seal lid 84 has a shape capable of closing the notch 86 and the insertion hole 36 without a gap, and an elastic member that is waterproof and moisture-proof is used. Thereby, the insertion holes 36 and 37 are sealed together with the rubber packing 38, and it is possible to prevent air (humidity) containing moisture sucked from the bathroom from leaking from the insertion holes 36 and 37 to the ceiling. Of course, when the relay cable 10 is used, the seal lid 84 is removed.

  The remaining portion of the air sucked from the suction grill 40a is exhausted from the exhaust port 20c through the ventilation air passage 25b.

  As a result, in the dry operation mode, the air path switching damper 24 is moved to the diversion position, the fan unit 21 is driven, and the heater 26 is energized, whereby a part of the air in the bathroom 101 is circulated. Steam and moisture in the bathroom 101 are exhausted while blowing hot air HA inside.

  In the cool breeze operation mode, the air path switching damper 24 is moved to the diversion position, and the heater 26 drives the fan unit 21 without energization, whereby a part of the air in the bathroom 101 is circulated to room temperature in the bathroom 101. The steam and moisture in the bathroom 101 may be exhausted while blowing air corresponding to the air. Independent of these operation modes, audio-related operations are executed in accordance with instructions from the audio operation panel 66. This instruction is often given before taking a bath.
