The lower end portion of the air passage 54 is opened to the outside of the cabinet body 3 (in detail, below) via the gap 53. Thereby, the lower end of the air passage 54 leads to the space below the cabinet body 3. Therefore, the air existing outside the cabinet body 3 can be introduced from the gap 53 into the lower end portion of the air passage 54. That is, the gap 53 introduces the air outside the cabinet body 3 into the air inlet of the air passage 54.

The upper end of the air passage 54 leads to the space 12 directly below the heat radiating portion 46 shown in FIG. In order to allow the upper end portion of the air passage 54 to pass to the space 12, for example, as shown in FIG. 7, the rear portion of the cover 43 is disposed on the mount 40, and is disposed above the upper end surface of the mount 40. At this time, a gap 52 is formed between the upper end surface of the pedestal 40 and the rear portion of the upper cover 43, and the upper end portion of the air passage 54 leads to the space 12 directly below the heat radiating portion 46 via the gap 52. Therefore, the air existing in the air passage 54 rises in the air passage 54 and is introduced into the space 12 through the gap 52, and thereafter, is led out from the space 12 through the opening 10 to the front of the cabinet body 3. Further, the means for bringing the upper end portion of the air passage 54 to the space 12 is not limited thereto. For example, the upper cover 43 may also form a hole through which the air passage 54 communicates with the space 12, so that the upper end of the air passage 54 leads to the space 12.

That is, the light guiding member 41 of each illuminating device 4 emits light by the light source 441 emitting light.

Specifically, the light irradiated from the light source 441 is introduced into the light guiding member 41 from the light incident portion 410, and thereafter, is diffused by the reflecting portion 411 toward the lower end side of the light guiding member 41, and is reflected toward the front side. This light is emitted from the light exit portion 412 toward the front side, and passes through the front sheet portion 470 of the front cover 47 between the adjacent doors 6 to be irradiated toward the front side of the cabinet 1. The user who uses the mirror surface provided on the front surface of the door 6 can perform makeup or face washing at the same time by using the illumination device 4 that emits light from the light-emitting portion 412 as described above.

When the light source 441 of the illumination device 4 emits light (when the light guide member 41 emits light), the light source 441 and the circuit board 440 provided with the light source 441 generate heat. The heat generated by the light source 441 or the circuit board 440 is transmitted to the heat radiating portion 46 provided on the upper surface of the outer surface of the interlocking cabinet body 3 via the heat sink 45, and is radiated to the heat radiating portion 46.

(Second Embodiment) Next, a second embodiment will be described. In the following, elements having the same functions as those of the first embodiment are denoted by the same reference numerals and the same reference numerals as those of the first embodiment, and the matters overlapping with the matters described in the first embodiment are omitted. Description.

In the first embodiment, as shown in Fig. 14, the projection 301 is provided on the upper surface of the cabinet body 3 so as to protrude upward by the recess 37 formed on the upper surface of the cabinet body 3. On the other hand, as shown in FIG. 15, the cabinet 1 of the present embodiment includes a spacer 95 different from the cabinet main body 3, and the spacer 95 is a protrusion 301A.

In the cabinet 1 of the present embodiment, only one door 6 is provided on the front side of the cabinet body 3. The door 6 is a mirror door with a front mirror surface. That is, the cabinet 1 of the present embodiment can be used as a mirror.

The lighting device 4 is disposed on both sides of the cabinet body 3. The basic configuration of each illuminating device 4 is the same as that of the first embodiment, and detailed description thereof will be omitted.

The spacer 95 is formed in a rectangular plate shape which is long in the left and right. One of the spacers 95 is a lower surface, and the other is an upper surface 950. The spacer 95 is attached to the upper surface of the cabinet body 3 (the upper surface of the ceiling portion 30). Specifically, the spacer 95 is attached to the ceiling portion 30 with the lower surface thereof along the horizontal upper surface of the ceiling portion 30 of the cabinet body 3. The spacer 95 is attached to the ceiling portion 30 using a fixing tool such as a screw.

The spacer 95 is disposed in the upper surface of the cabinet body 3 in the middle portion in the left-right direction. Thereby, the concave portion 37A is formed on both outer sides of the spacer 95. Each of the recesses 37A is open to the front, the upper side, the rear side, and the side opposite to the side opposite to the spacer 95. In the respective recessed portions 37A, the heat radiating portion 46 of the illuminating device 4 and the heat radiating portion cover 48 are disposed in the same manner as in the first embodiment.

The upper surface 950 of the spacer 95 is horizontal. The upper surface 950 of the spacer 95 is located above the upper surface of the heat dissipating portion 46 provided on the upper surface of the cabinet body 3. As shown in FIG. 17, the upper surface 950 of the spacer 95 is located above the upper surface of the heat sink cover 48 of the heat sink portion 46.

The spacer 95 is disposed at a position away from the heat radiating portion 46 and the heat sink cover 48 toward the side. Thereby, the heat of the heat radiating portion 46 is hard to pass to the spacer 95.

When the spacer 301A is the spacer 95 as described above, the heat radiating portion 46 or the heat radiating portion cover 48 may not protrude upward from the upper end of the protruding body 301A. For example, as shown in FIG. 16, when an object 97 (for example, another installation such as a closet) is present above the cabinet body 3, the object 97 can come into contact with the upper surface of the contact protrusion 301A, and the protrusion 301A can be perfectly disposed. Further, a gap may be formed between the lower surface of the object 97 and the upper surface of the protrusion 301A, and the object 97 may be disposed in the vicinity of the protrusion 301A.

The upper surface 950 of the spacer 95 is located above the heat sink cover 48, and may be between the upper surface of the heat sink cover 48 and the lower surface of the fixture 97 (the upper surface of the heat sink 46 and the surface of the heat sink 46) Between the lower surfaces, a heat dissipation gap 96 is formed. Therefore, the heat generated in the heat radiating portion 46 can be efficiently diffused.

(Third embodiment) Next, a third embodiment will be described. In the following, elements having the same functions as those of the first embodiment are denoted by the same reference numerals and the same reference numerals as those of the first embodiment, and the matters overlapping with the matters described in the first embodiment are omitted. Description.

In the first embodiment and the second embodiment, the illumination device 4 is provided in the cabinet 1. On the other hand, the illuminating device 4 of this embodiment is provided in the bathroom 8 as shown in FIG.

In detail, the lighting device 4 is provided at a corner (corner) of the bathroom 8. The heat radiating portion 46 is provided outside the bathroom 8. Specifically, the heat radiating portion 46 is disposed in the ceiling of the bathroom 8 . Moreover, in the example of FIG. 18, the heat radiating part cover 48 is abbreviate|omitted.

The light guiding member 41 of the illuminating device 4 emits light toward the front side by the light source 441. Thereby, the bathroom 8 can be illuminated. When the light source 441 emits light, the heat generated by the light source 441 or the circuit board 440 can be diffused by the heat radiating portion 46 located outside the bathroom 8.

The illuminating device 4 of the first to third embodiments described above has the following first feature. In the first feature, the illumination device 4 includes a circuit board 440, a light source 441, and a vertically long light guiding member 41. The light source 441 is disposed on a lower surface of the circuit substrate 440. The light guiding member 41 includes a light incident portion 410 and a light exit portion 412. The light incident portion 410 is formed at an upper end portion of the light guiding member 41. The light exit portion 412 is formed on the front surface of the light guiding member 41. The illumination device 4 introduces light emitted from the light source 441 from the light incident portion 410, and reflects the light toward the front side to be emitted from the light exit portion 412. The lighting device 4 further includes a heat radiating portion 46. The heat dissipation portion 46 is provided along the circuit substrate 440 to thermally connect the circuit substrate 440. At least a portion of the upper surface of the heat dissipation portion 46 is a heat dissipation surface 463 that is not shielded by the circuit substrate 440.

The illuminating device 4 having the first feature allows the light irradiated from the light source 441 to be emitted toward the front side of the light guiding member 41 to illuminate the front side of the light guiding member 41. When the light source 441 emits light, the heat generated by the light source 441 or the circuit substrate 440 can be transmitted to the heat radiating portion 46 to be diffused. Further, the air heated by the heat radiated from the heat radiating portion 46 toward the heat radiating surface 463 on the upper side rises and is away from the heat radiating portion 46. Therefore, the heat dissipation of the heat radiating portion 46 can be improved. As a result, in the illumination device 4, it is difficult to cause a malfunction due to heat generated when the light source 441 emits light. Moreover, it is not easy to be hot when the lighting device 4 is provided.

Further, the illuminating device 4 of the first to third embodiments can selectively have the following second to fifth features. That is, the second to fifth features are arbitrary features.

In the second feature, as in the first feature, the heat radiating portion 46 is provided along the upper surface of the circuit board 440. At this time, the entire upper surface of the heat dissipating portion 46 can be a heat dissipating surface 463, which can further improve heat dissipation.

In the third feature, as in the first or second feature, the heat radiating portion 46 is expanded outward in the horizontal direction from the circuit board 440. At this time, the heat dissipation surface 463 of the heat dissipation portion 46 can be increased to further improve heat dissipation.

In the fourth feature, as in any one of the first to third features, the heat radiating portion 46 has a flat shape. At this time, it is possible to suppress the heat radiating portion 46 from being large and to increase the area of the heat radiating surface 463.

In the fifth feature, as in any one of the first to fourth features, the light source 441 is a light-emitting diode. At this time, the heat generated when the light source 441 of the light-emitting diode is illuminated can be diffused by the heat radiating portion 46.

Further, the mirror cabinet of Document 1 includes a cabinet body having a storage space, and a mirror plate that can be arbitrarily opened and closed by closing the storage space. In the mirror plate, in order to illuminate the user in front, there is a lighting device comprising a plurality of light-emitting diodes.

Here, in the mirror cabinet of Document 1, when a large number of light-emitting diodes emit light, it causes sweltering, and thus a malfunction of the lighting device may occur due to heat.

The cabinet 1 of the first and second embodiments is intended to be less sweltering when the illuminating device 4 is used, and it is less likely to cause malfunction of the illuminating device 4 or the like.

In order to achieve the object, the cabinet 1 of the first embodiment and the second embodiment has the following sixth feature. In the sixth feature, the cabinet 1 includes the cabinet body 3 and the lighting device 4. The illuminating device 4 has the first to fifth features. The light guiding member 41 is provided at a front portion of the cabinet body 3. The heat radiating portion 46 is provided on the upper surface of the cabinet body 3.

The cabinet 1 having the sixth feature allows the light irradiated from the light source 441 to be emitted toward the front side of the light guiding member 41 to illuminate the front of the cabinet body 3. The heat generated by the circuit board 440 or the light source 441 can be transmitted to the heat radiating portion 46 provided on the outer surface of the outer surface of the cabinet body 3 to be diffused. Therefore, when the illuminating device 4 is used, it is not easy to be hot at the portion where the light source 441 or the circuit board 440 is provided, and it is difficult to cause malfunction of the illuminating device 4 due to heat. Further, the heat dissipating portion 46 is provided on the upper surface of the cabinet body 3, whereby the high-temperature heat dissipating portion 46 is less likely to contact the user, and safety can be improved.

Further, the cabinet 1 of the first embodiment and the second embodiment can selectively have the following seventh to ninth and eleventh to thirteenth features. Further, the cabinet 1 of the second embodiment selectively has the following tenth feature. That is, the seventh to thirteenth features are arbitrary features.

In the seventh feature, as in the sixth feature, the cabinet body 3 includes a plurality of storage spaces 34 and storage grooves 72. Each storage space 34 is open to the front. The plurality of storage spaces 34 are arranged side by side. The storage groove 72 has a vertically long shape and is provided at a portion between the storage spaces 34 arranged side by side in the cabinet body 3. The storage groove 72 opens toward the front. The light guiding member 41 is disposed in the housing groove 72. A longitudinally long air passage 54 is formed on the rear side of the light guiding member 41 in the housing groove 72. The lower end of the air passage 54 leads to the space on the outer side of the cabinet body 3. Immediately below the heat radiating portion 46, a space 12 opening to the outside of the cabinet body 3 is formed. The upper end of the air passage 54 leads to the space 12. At this time, the air outside the cabinet main body 3 can be introduced from the lower end portion toward the air passage 54, and the air is discharged to the space outside the cabinet main body 3 via the space 12. Therefore, the heat existing in the space 12 formed between the lower surface of the heat radiating portion 46 and the upper surface of the cabinet body 3 can be efficiently discharged. Thereby, in the portion where the circuit board 440 is provided, it is less likely to be stuffy.

In the eighth feature, as in the sixth or seventh feature, the circuit board 440 is provided with a circuit that can point to the light source 441. The cabinet 1 contains a power source 92 that is electrically connected to the circuit. The power source 92 is disposed behind the cabinet body 3. At this time, the electric device can be disposed at a position where it is difficult to interfere when the storage space 34 of the cabinet 1 is used. Moreover, the electrical equipment is disposed behind the cabinet body 3, whereby the user's hand is less likely to be in contact with the electrical connection portion, and safety can be improved.

In the first embodiment and the second embodiment, in particular, the power source 92 is disposed above the storage space 34C of the cabinet body 3. Therefore, the electric device is less likely to interfere with the user who uses the storage space 34C.

In the ninth feature, as in any one of the sixth to eighth aspects, the upper surface of the cabinet body 3 is provided with a protruding body 301 (projecting body 301A) that protrudes upward. The upper end of the protruding body 301 (the protruding body 301A) is disposed above the heat radiating portion 46. At this time, the heat radiating portion 46 or the heat radiating portion cover 48 covering the upper surface of the heat radiating portion 46 does not protrude upward from the upper end of the protruding body 301 (the protruding body 301A). Therefore, it is possible to prevent the heat radiating portion cover 48 or the heat radiating portion 46 from being deformed by the load placed on the upper surface of the upper surface of the cabinet body 3 (the recessed portion 37A).

In the tenth feature, as the ninth feature, the protruding body 301A is provided separately from the cabinet body 3, and is provided with a spacer 95 on the upper surface of the cabinet body 3. When the protrusion 301A is configured by the spacer 95 provided separately from the cabinet body 3, the heat dissipation portion 46 may not protrude upward from the upper end of the protrusion 301A.

If the cabinet body 3 is made of wood, it is difficult to form the protrusion 301 in the cabinet body 3. Therefore, when the cabinet body 3 is made of wood, the spacers 95 are attached only to the upper surface of the cabinet body 3, whereby the protrusions 301A can be easily provided. Further, the cabinet body 3 of the second embodiment is not limited to wood, and may be made of, for example, synthetic resin.

In the eleventh feature, in any one of the sixth to tenth aspects, the illumination device 4 includes a heat dissipation portion cover 48 that covers a portion where the heat dissipation portion 46 is exposed on the upper surface side of the cabinet body 3. At this time, the heat dissipating portion cover 48 may cover the heat dissipating portion 46 provided on the upper surface (outer surface) of the cabinet body 3. Therefore, the heat radiating portion 46 is less likely to directly contact the user, and safety can be improved.

In the twelfth feature, as in the eleventh feature, a concave portion 37 (recessed portion 37A) is formed on the upper surface of the cabinet body 3. A heat dissipating portion 46 and a heat dissipating portion cover 48 covering the upper surface of the heat dissipating portion 46 are disposed in the recess portion 37 (the recess portion 37A). The upper surface of the heat sink cover 48 is disposed at a position lower than the upper surface of the cabinet body 3 or the same height as the upper surface of the cabinet body 3. At this time, it is possible to suppress deformation or the like by applying a load placed on the heat radiating portion cover 48 or the heat radiating portion 46 to a place other than the concave portion 37 (recessed portion 37A) on the upper surface of the cabinet body 3.

In the thirteenth feature, as in the twelfth feature, the heat radiating portion 46 is a heat radiating plate disposed along the bottom surface of the recessed portion 37 (the recessed portion 37A). A space 12 open to the outside of the cabinet body 3 is formed between the lower surface of the heat radiating portion 46 and the bottom surface of the recess portion 37 (the recess portion 37A). The heat sink cover 48 includes a locking portion 486. The locking portion 486 is fixed by being caught by the lower surface of the heat radiating portion 46, and is disposed between the lower surface of the heat radiating portion 46 and the bottom surface of the recess portion 37 (the recess portion 37A). At this time, the heat generated in the heat radiating portion 46 can be released from the space 12 toward the outside of the cabinet body 3. Further, the heat dissipating portion cover 48 is formed to be fixed to the lower surface of the heat dissipating portion 46, and is disposed at a locking portion 486 between the lower surface of the heat dissipating portion 46 and the bottom surface of the recess portion 37. Therefore, for example, when a downward load is applied to the heat sink cover 48 or the like, the load can be received by the bottom surface of the recess 37 (recess 37A) via the locking portion 486, and the heat sink cover 48 can be prevented from being deformed or the like.

In the first to third embodiments described above, the entire upper surface of the heat dissipation portion 46 is a heat dissipation surface 463 that is not shielded by the circuit board 440. However, the heat dissipation portion 46 may also be disposed along, for example, the lower surface of the circuit substrate 440. At this time, only a part of the upper surface of the heat radiating portion 46 is a heat radiating surface 463 which is not shielded by the circuit board 440. That is, in the heat radiating portion 46, at least a part of the upper surface may be a heat radiating surface 463 which is not shielded by the circuit board 440.

Further, the heat dissipation portion 46 of the first to third embodiments may be thermally connected to the circuit board 440 while maintaining electrical insulation from the circuit board 440. The heat radiating portion 46 may be directly bonded to, for example, the circuit board 440, or may be indirectly joined to the circuit board 440 via a member other than the heat sink 45.

Further, the heat radiating portions 46 of the first to third embodiments described above are expanded outward in the horizontal direction from the circuit board 440. However, the heat dissipating portion 46 provided along the upper surface of the circuit board 440 may not protrude further outward than the circuit board 440 in plan view.

The heat radiating portion 46 of the first to third embodiments is a flat heat radiating plate. However, the shape of the heat radiating portion 46 is not limited to a plate shape, and may be a block shape or a fin shape.

In the light source 441 of the first to third embodiments, only one of the circuit boards 440 is provided to suppress the amount of heat generation, but a plurality of light sources 441 may be provided on the circuit board 440. Further, although the light source 441 of the first to third embodiments is a light-emitting diode, it may be another light source such as a bulb. The heat sink cover 48 may also be omitted.

Further, the illuminating device 4 of the first to third embodiments may be provided in a room other than the cabinet 1 or a room other than the bathroom 8 or the like.

In the first embodiment and the second embodiment, the heat dissipating portion 46 is provided in the concave portion 37 (the recess portion 37A) formed on the upper surface of the cabinet body 3. However, the heat radiating portion 46 may also be disposed along the upper surface of the cabinet body 3 where the recess 37 (recess 37A) is not formed.
