Description

  The present invention relates to a mirror cabinet having an illumination function.

  Conventionally, when attaching a lighting fixture to a mirror cabinet of a vanity, illuminate the entire front of the vanity by fixing fluorescent or incandescent lamps in the upper part of the three-sided mirror or in the gap between the mirror doors of the three-sided mirror A general structure is used (see, for example, Patent Document 1).

  However, when a fluorescent lamp or the like is fixed above the three-sided mirror, in order to illuminate the entire front surface of the wash basin, it is necessary to install a large lighting cover so that it protrudes forward from the upper side of the three-sided mirror. Therefore, there is a problem that the mirror area in the three-sided mirror is greatly restricted. On the other hand, when a fluorescent lamp or the like is fixed in the gap between the mirror doors of the three-sided mirror, it is necessary to provide an illumination lamp space with a width of about 100 mm in order to store the fluorescent lamp. There is a problem that the area is greatly restricted.

JP 2001-78909 A

  The present invention has been made in view of the above circumstances, and its purpose is to brighten the face and hand portion of a person standing in front of the mirror door while sufficiently securing the mirror area of the mirror door. The object is to provide a mirror cabinet that can be illuminated.

  In order to solve the above-described problems, the present invention is characterized by the following configurations.

  A mirror cabinet in which storage spaces 4 and 5 are provided on the back side of adjacent mirror doors 2 and 3, and the storage spaces 4 and 5 of the mirror doors 2 and 3 are partitioned by vertical plates 6 arranged in the vertical direction D. In addition, a storage recess 11 having a substantially U-shaped cross-section in the plane B opened in the front B is formed in the vertical plate 6 in a vertically long shape, and the front opening 12 of the storage recess 11 is formed in the vertical plate 6. The front end surface 7 is opened in a vertically long shape at a portion facing the gap S between the adjacent mirror doors 2 and 3 with the vertical plate 6 interposed therebetween. The light guide plate 10 made of a light guide material is stored vertically in the storage recess 11, the back end surface 10 a of the light guide plate 10 is a light incident surface 13 on which light from the light source 15 is incident, and the end surface on the back side. The front end face 10b opposite to the light entrance face 10a is used as a light exit face 14 for emitting the light incident from the light entrance face 13 as the strip-shaped illumination light R, and the light exit face 14 is adjacent to the front opening 12 in the mirror door. It is characterized by being arranged facing the gap S between two or three.

  With such a configuration, when the light source 15 is turned on, a gap between the adjacent mirror doors 2 and 3 with the strip-shaped illumination light R from the light exit surface 14 of the light guide plate 10 stored vertically in the vertical plate 6 is provided. Since it irradiates the front B through S, the face and hand part of the person in front of the mirror doors 2 and 3 can be sufficiently illuminated. In addition, the light guide plate 10 can be compactly and well stored in the vertical plate 6 that partitions the storage spaces 4 and 5, and the strip-shaped illumination light from the light exit surface 14 is provided between the adjacent mirror doors 2 and 3. Since it is only necessary to provide a narrow gap S through which R can pass, unlike the case of providing a wide illumination space for storing a conventional fluorescent lamp, the mirror area in the mirror doors 2 and 3 is not greatly restricted. .

  In the present invention, it is preferable that the light exit surface 14 of the light guide plate 10 is disposed so as to protrude from the front opening 12 of the vertical plate 6 toward the front B position where it does not interfere with the mirror doors 2 and 3. In this case, the light exit surface 14 of the light guide plate 10 is flush with the mirror surface of the mirror doors 2 and 3 while preventing interference between the light guide plate 10 and the mirror doors 2 and 3 when opening and closing the mirror doors 2 and 3. As a result, a continuous appearance with no step between the light exit surface 14 and the mirror surface can be exhibited, thereby improving the design.

  In the present invention, the light source 15 is preferably an LED 15a. In this case, mirror illumination can be performed with a small size, a long life, and a low power consumption as compared with an illumination lamp such as a fluorescent lamp or an incandescent lamp.

  In the present invention, the vertical plate 6 is preferably formed by housing the light guide plate 10 inside an aluminum extruded material having a U-shaped cross section. In this case, the thickness of the entire vertical plate 6 including the light guide plate 10 can be kept thin while securing the strength of the light guide plate 10 with the aluminum extrusion molding material, and the extrusion molding material is made of metal such as aluminum. It can also serve as a heat dissipation measure for lighting.

  The mirror cabinet according to the present invention vertically accommodates a light guide plate in which a rear end surface forms a light incident surface and a front end surface forms a light exit surface in a storage recess that is opened forward and is provided inside the vertical plate. The light emitting surface of the light guide plate faces the gap between the mirror doors adjacent to each other with the vertical plate sandwiched from the front opening of the storage recess, thereby adjoining the strip-shaped illumination light emitted from the light emitting surface of the light guide plate It can irradiate forward through the gap between the mirror doors. By using the vertical plate that partitions the storage space, the light guide plate can be packed in a compact and well-contained manner, and the strip illumination can be used between adjacent mirror doors. Since it is sufficient to secure a narrow gap through which light can pass, the mirror area in the mirror door is not greatly restricted, unlike the case of providing a wide space for a illuminating lamp for a conventional fluorescent lamp. As a result, the face and hand portion of the person standing in front of the mirror door can be brightly illuminated by the strip-shaped illumination light while sufficiently securing the mirror area of the mirror door.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  FIG. 3 shows an example of the mirror cabinet 1 used for the vanity of this embodiment.

  A three-sided mirror having a central mirror door 2 and mirror doors 3 and 3 on both sides is disposed on the front surface of the mirror cabinet 1 disposed above the washstand 20.

  As shown in FIG. 4, the mirror cabinet 1 has a space portion surrounded by a top plate 21, both side plates 22, a back plate (not shown), and a bottom plate 23, and this space portion is arranged in the vertical direction D. The central storage space 4 that is opened and closed by the central mirror door 2 and the storage spaces 5 and 5 that are opened and closed by the mirror doors 3 and 3 on both sides, respectively. It is divided into. For example, as shown in FIG. 6, each mirror door 2, 3 has a mirror panel 17 fixed to the surface of a base panel 16 and a vertical sash 18 fitted into the outer peripheral portion thereof.

  As shown in FIG. 4B, the base end 2a of the central mirror door 2 is connected to a slide hinge 24 provided on the side surface of the left vertical plate 6, and the front end 2b of the mirror door 2 is It is received by one door receiving surface 8 (see FIG. 1) provided on the front end surface 7 of the right vertical plate 6. For example, as shown in FIGS. 6 (a) and 6 (b), the slide hinge 24 includes a parallel link plate 25 that can be expanded and folded so that the mirror door 2 can be opened at a wide angle. With this slide hinge 24, the base end 2a of the mirror door 2 can be rotated at a position where it does not interfere with the light guide plate 10 described later. In addition, about the concrete structure of the slide hinge 24, the technique well-known by Unexamined-Japanese-Patent No. 2003-189950 etc. which this applicant has already disclosed can be employ | adopted.

  The base end portion 3a of the left side mirror door 3 is connected to an open / close hinge (not shown) provided on the side surface portion of the left side plate 22, and the front end portion 3b is provided on the front end surface 7 of the left vertical plate 6. It is received by the door receiving surface 8 (FIG. 1).

  The base end 3 a of the right side mirror door 3 is connected to an open / close hinge (not shown) provided on the side of the right side plate 22, and the tip 3 b is provided on the front end 7 of the right vertical plate 6. It is received by the door receiving surface 9 (FIG. 1).

  In this example, the left and right vertical plates 6 and 6 have door receiving surfaces 8 and 9 (FIG. 5) on both sides in the width direction A of the front end surface 7 and door receiving surfaces 9 only on one side in the width direction A, respectively. The other side in the width direction A is divided into the hinge mounting surface 30 (FIG. 6), but is common in the configuration including the storage recess 11 opened to the front B inside the vertical plate 6. .

  The left and right vertical plates 6 are integrally formed of an aluminum extruded material having a U-shaped cross section. As shown in FIG. 1, a front opening 12 opens vertically from the left and right aluminum extrusion-molded portions 6 a, 6 a toward the front B. 1 is a dowel hole for connecting the aluminum extruded portion 6a and the top plate 21 using a connecting metal fitting (not shown), and 27 is projected from both inner wall surfaces of the storage recess 11 respectively. 1 and 2, reference numerals 28 and 29 in FIG. 1 and FIG. 2 denote plate members that respectively close the upper and lower end portions of the storage recess 11.

  As shown in FIGS. 1 and 2, the light guide plate 10 is stored in the vertical orientation in the storage recess 11 of the vertical plate 6. The light guide plate 10 is made of a translucent material such as acrylic resin or polycarbonate resin, and is formed in a rectangular shape that is long in the vertical direction D. A light incident surface 13 for taking in light from the light source 15 is provided on the end surface 10 a on the back side of the light guide plate 10, and light from the light source 15 incident on the light incident surface 13 is applied to the front end surface 10 b from the strip illumination light R. The light emitting surface 14 to be emitted is provided, and the other upper and lower end surfaces and both side surfaces other than the light incident surface 13 and the light emitting surface 14 are light reflecting surfaces 60a, 60b, 60c, and 60d, respectively. As a method for forming the light reflection surface 60, for example, a reflection process such as aluminum deposition is performed on the outer surface, or a scattering reflection surface is formed.

  The light exit surface 14 of the light guide plate 10 is disposed facing the gap S between the adjacent mirror doors 2 and 3 from the front opening 12 of the vertical plate 6. In this example, the light emitting surface 14 protrudes by a predetermined dimension from the door receiving surfaces 8 and 9 toward the front B position that does not interfere with the adjacent mirror doors 2 and 3 from the front opening 12 of the vertical plate 6. Yes. As shown in FIG. 5, the projecting dimension is preferably set so that the mirror panel 17 and the light exit surface 14 of the mirror doors 2 and 3 in the closed state are substantially flush with each other as shown in FIG. . Of course, the light exit surface 14 is not limited to projecting forward B from the front opening 12, and at least the strip-shaped illumination light R emitted from the light exit surface 14 is forward B from the gap S between the mirror doors 2 and 3. What is necessary is just to make it irradiate toward.

  A light source 15 is disposed facing the light incident surface 13 of the light guide plate 10. As shown in FIG. 2, the light source 15 includes a plurality of upper and lower LEDs (light emitting diodes) 15a. Each LED 15a is mounted on the LED substrate 15b so that the optical axis of the LED 15a is oriented in a direction perpendicular to the light incident surface 13 of the light guide plate 10.

  Thus, according to the above configuration, when the LED 15a is turned on, the light of the LED 15a is incident from the light incident surface 13 of the light guide plate 10 as shown in FIGS. It spreads away from the light incident surface 13 and proceeds toward the light emitting surface 14 while being specularly reflected by the light reflecting surfaces 60 a to 60 d on both upper and lower end surfaces and both side surfaces, and is almost constant over the entire surface of the light emitting surface 14. The light is emitted as a light amount. As a result, the strip-shaped illumination light R with no unevenness in brightness is irradiated toward the front B through the gap S between the adjacent mirror doors 2 and 3, so that in front of the mirror doors 2 and 3. Can illuminate the face and hand of a person.

  Further, the light exit surface 14 of the light guide plate 10 is exposed from the front opening 12 provided on the center side in the width direction A of the front end surface 7 of the vertical plate 6, thereby interfering with the light guide plate 10 and the mirror doors 2 and 3. It becomes possible to arrange the light emitting surface 14 of the light guide plate 10 in the gap S between the adjacent mirror doors 2 and 3 while preventing the above. In addition, in this example, since the light exit surface 14 of the light guide plate 10 is disposed so as to be substantially flush with the mirror panel 17 of the mirror doors 2 and 3, the mirror panel 17 and the light exit surface 14 are stepped. When the LED 15a is turned on in this state, the gap S between the adjacent mirror panels 17 shines in a band shape, and the design is further improved.

  Further, since it is only necessary to provide a narrow gap S corresponding to the thickness of the light guide plate 10 between the adjacent mirror doors 2 and 3, unlike the case of providing a wide illumination space for a conventional fluorescent lamp, the mirror The mirror area at the doors 2 and 3 is not greatly restricted. Moreover, since the light guide plate 10 can be stored in a compact and well-contained manner within the vertical plate 6, an increase in the thickness of the vertical plate 6 can be prevented, and the storage spaces 4 and 5 partitioned by the vertical plate 6 are not narrowed.

  Note that when a fluorescent lamp or an incandescent lamp is used as the light source 15, there is a problem that heat is generated and power consumption is large, and the life is short and needs to be replaced. Thus, a small and compact vertical plate 6 with an illumination function that has a long life and operates with a low electric energy can be obtained.

  In addition, by forming the vertical plate 6 with an aluminum extrusion molding material, the strength of the light guide plate 10 can be increased, and the overall thickness of the vertical plate 6 housing the light guide plate 10 can be reduced while securing the strength. . In addition, by using a metal, it also serves as a heat dissipation measure for lighting. In addition, since the cross-sectional shape is constant regardless of where the vertical plate 6 is cut in the vertical direction D by extrusion molding, there is an advantage that it can be used after being cut into a predetermined length according to the cabinet size.

  In the embodiment, at least one of both sides in the width direction A of the front end surface 7 of the vertical plate 6 is a door receiving surface 8 (9), and the other is a door mounting surface 30 for attaching a hinge to the side surface of the vertical plate 6 (FIG. 6). However, both of the side portions of the vertical plate 6 may be the door mounting surface 30. That is, it is only necessary that at least one of the door mounting surface 30 or the door receiving surface 8 (9) is provided on the vertical plate 6.

  In the above embodiment, the vertical plate 6 is an aluminum extrusion-molded product. However, the light guide plate 10 may be sandwiched between two independent metal plates, and these may be assembled together.

  In the above-described embodiment, the back side of the light guide plate 10 is illustrated as the installation location of the LED 15a. In addition, for example, the LED 15a is installed on the upper side or the lower side of the light guide plate 10, and the light of the LED 15a is used using, for example, an optical fiber bundle. A structure in which the light is transmitted to the light incident surface 13 on the back side of the light guide plate 10 is also possible.

  In addition, although the light guide plate 10 and the LED 15a are configured separately, the LED 15a can be integrally formed on the end surface of the light guide plate 10 in an embedded manner.

  The mirror cabinet 1 provided with the vertical plate 6 with an illumination function of the present invention can be widely applied to various equipment units such as a system kitchen other than the vanity.
