  Hereinafter, an example of an embodiment of the present invention will be described with reference to the accompanying drawings.

  As shown in FIG. 2, the antifogging mirror 1 according to the first embodiment is formed by fixing a heater unit 20 with a heater wire 2 on the back side of the mirror and covering the heater unit 20 with a waterproof cover 10. A lead wire 8 for supplying power is connected to the heater unit 20. The anti-fogging mirror 1 is attached to the bathroom wall surface 7 with upper and lower metal fittings 11. The lead wire 8 is pulled up from the hole provided in the bathroom wall surface 7 through the back side of the bathroom wall surface 7 to the back of the bathroom ceiling. As shown in FIG. 1A, the heater wire 2 is connected in the terminal box 9 and connected to the lead wire 8. The heater wire 2 has a uniform thickness, and is supplied with electric power through the lead wire 8 to transmit heat to a certain range around the heater wire 2. The anti-fogging mirror 1 may be attached to a bathroom vanity.

  The heater wire 2 is wired to the heater unit 20 in a crank shape, a U-shape or meandering, and stretched in a planar shape. In order to keep the heat generation amount per unit area of the anti-fogging region where the heater wire 2 is stretched in a plane, the heater wire 2 is basically the adjacent parallel heater wire in the entire anti-fogging region. Wiring is performed so that the distance between the two is constant.

The second anti-fogging region 4 is wired so as to form the pattern. The first anti-fogging region 3, the constricted anti-fogging region 5, and the second anti-fogging region 4 are arranged in a line from top to bottom in this order. Here, the first anti-fogging region 3 is narrower in the left-right direction than the second anti-fogging region 4. The narrow anti-fogging region 5 is narrower in the left-right direction than the first anti-fogging region 3 and the second anti-fogging region 4. Further, the length in the vertical direction is set so that the constricted anti-fogging region 5 is shorter than the first anti-fogging region 3 and the first anti-fogging region 3 is shorter than the second anti-fogging region 4. Since the constricted anti-fogging region 5 is wired so as to have a neck pattern, the length in the vertical direction is shorter than the first anti-fogging region 3 and the second anti-fogging region 4.

  The first anti-fogging region 3, the constricted anti-fogging region 5, and the second anti-fogging region 4 are wired with heater wires 2 so as to be symmetrical. Therefore, in the following, only the right half of the first anti-fogging region 3, the constricted anti-fogging region 5, and the second anti-fogging region 4 will be described.

The parallel contour inner parallel lines 24 are wired with a longer pitch than the reference pitch described above. Here, the contour line 21 and the contour inner parallel line 24 that is adjacent to and parallel to the inner side of the non-adjacent non-proximity region 31 other than the end region 30 of the first anti-fogging region 3 are the above-described reference. Wired with a pitch. The first anti-fogging region 3 is composed of the end region 30 and the non-proximity region 31. The end region 30 is desirably a region that is about a quarter to a fifth of the first anti-fogging region 3.

  Further, in the antifogging mirror 1 of the present embodiment, the contour line 22 and the contour inner parallel line 25 adjacent to and parallel to the inner side thereof, which are wired in the constricted antifogging region 5, are longer than the reference pitch described above. Wired with a pitch.

  Moreover, in the anti-fog mirror 1 of this embodiment, the outline 23 and the inner side (lower side) wired in the edge part area | region 40 of the 2nd anti-fog area | region 4 near the 1st anti-fog area | region 3 are provided. Are parallel to the contour inner parallel lines 26 that are adjacent to each other and are arranged at a longer pitch than the above-described reference pitch. Here, the contour line 23 and the contour inner parallel line 26 that is adjacent to and parallel to the inner side of the non-adjacent non-proximity region 41 other than the end region 40 of the second anti-fogging region 4 are the above-described reference. Wired with a pitch. The second anti-fogging region 4 includes the end region 40 and the non-proximity region 41. The end region 40 is preferably a region that is about one quarter to one fifth of the second anti-fogging region 4.

  Further, in the present embodiment, a plurality of U-shapes opening upward are arranged on the left and right sides and adjacent to the inner portions of the contour lines 21 and 23 of the first antifogging region 3 and the second antifogging region 4. The heater wire 2 is wired in a pattern in which the upper ends of the U-shape are connected by straight lines or curves.

  In the first anti-fogging region 3, the contour inner parallel line 24 wired to the end region 30 at the lower end is wired so as to be inclined upward as it goes to the right. The plurality of U-shaped heater wires 2 that are wired on the inner side (upper side) and that open upward are wired such that the bottom side 27 is positioned upward in the right direction along the slope. Yes. The contour inner parallel lines 24 of the end region 30 and a plurality of U-shaped bases 27 on the inner side (upper side) are also wired with a longer pitch than the reference pitch described above. That is, in the present embodiment, the end region 30 of the first anti-fogging region 3 indicates a range from the contour line 21 to the plurality of U-shaped bases 27. In this embodiment, a curved line 28 that connects a plurality of U-shaped adjacent upper ends that open upward is a contour inner parallel line 24 at the upper end of the first antifogging region 3.

  Moreover, in the 2nd anti-fog area | region 4, the outline 23 of the edge part area | region 40 of an upper end part and the some upper ends adjacent to the upper part which were wired by the inner side (lower side) and opened upwards are connected. The straight line 29 is wired with a longer pitch than the reference pitch described above. That is, in this embodiment, the edge part area | region 40 of the 2nd anti-fog area | region 4 has shown the range from the outline 23 to the straight line 29 which connects a some U-shaped upper end. Note that a plurality of U-shaped bases 27 that open upward are contour lines 23 at the lower end of the second anti-fogging region 4 in this embodiment.

  In the antifogging mirror 1 of the present embodiment having the above-described configuration, the contour line 21 includes the end region 30 of the first antifogging region 3, the constricted antifogging region 5, and the end region 40 of the second antifogging region 4. , 22, 23 and the contour inner parallel lines 24, 25, 26 are wired with a longer pitch than the reference pitch.

  By wiring in this way, the wiring density of the heater wire 2 in the end region 30 of the first anti-fogging region 3, the constricted anti-fogging region 5, and the end region 40 of the second anti-fogging region 4 is determined as a reference. The wiring density of the heater wires 2 in the non-proximity regions 31 and 41 where the heater wires 2 are wired at a pitch can be reduced. That is, the heat generation amount per unit area of the end region 30 of the first anti-fogging region 3, the constricted anti-fogging region 5, and the end region 40 of the second anti-fogging region 4 can be suppressed. The wiring density of the end region 30 of the first anti-fogging region 3, the constricted anti-fogging region 5, and the end region 40 of the second anti-fogging region 4 can maintain the anti-fogging function, and is also anti-fogging. It is set so that heat can be generated with a calorific value per unit area where the pattern is difficult to spread. Therefore, the antifogging mirror 1 of the present embodiment is surrounded by the end region 30 of the first antifogging region 3, the constricted antifogging region 5, and the end region 40 of the second antifogging region 4. It is possible to suppress the transfer of heat to the part where no wiring is provided. The wiring density described above is the sum of the lengths of all the heater wires 2 wired in the anti-fogging region, divided by the area of the anti-fogging region.

  From the above, the anti-fogging mirror 1 of this embodiment is constricted between the first anti-fogging region 3 and the second anti-fogging region 4 when power is supplied to the heater wire 2 in a situation where the entire mirror surface is easily clouded. The antifogging pattern 6 can be clearly formed on the mirror surface. Therefore, the anti-fog mirror 1 according to the present embodiment has an anti-fog pattern 6 (people) that is as close as possible to the outline of the wiring pattern of the heater wire 2 wired on the back side of the mirror until the bather comes out immediately after entering the bathroom with high humidity. Can be displayed on the mirror surface.

  As a modification of the present embodiment, the first anti-fogging region 3 and the second anti-fogging region 4 may have a plurality of upper and lower U-shaped wiring patterns arranged in the left or right direction. .

  Further, as a modified example of the present embodiment, the first anti-fogging region 3 and the second anti-fogging region 4 are not only the end regions 30 and 40 on the side close to each other, but the contour lines 21 and 23 in the entire contour. The contour inner parallel lines 24 and 26 may be wired with a longer pitch than the reference pitch described above. In this way, it is possible to form an antifogging pattern 6 having substantially the same shape as the first antifogging region 3, the second antifogging region 4, and the constricted antifogging region 5, and the entire outline becomes clear.

  Further, as a modification of the present embodiment, the heat generation amount per unit area may be adjusted by other means instead of adjusting the heat generation amount per unit area by the arrangement density of the heater wires 2. . For example, by changing the amount of heat generated per unit length of the heater wire 2 depending on the arrangement location, or by using a hot water pipe in which hot water flows inside instead of the heater wire 2, the amount of heat generated per unit area is adjusted. Also good.

  Next, the antifogging mirror 1 according to the second embodiment of the present invention shown in FIG. 3 will be described. The anti-fog mirror 1 of this embodiment differs in the wiring pattern of the heater wire 2 from 1st embodiment.

The region 3 and two second anti-fogging regions 4 are connected to each other to form two constricted anti-fogging regions 5. The first anti-fogging region 3 forms an animal face silhouette pattern, and the second anti-fogging region 4 and the constricted anti-fogging region 5 form an animal ear silhouette pattern.

  In this embodiment, the second anti-fogging region 4 and the constricted anti-fogging region 5 are added to the wiring density of the heater wires 2 from the first anti-fogging region 3 (the length of all the heater wires 2 wired in each anti-fogging region is added). The wiring pattern is formed so that the sum of those divided by the area of each anti-fogging region is low. The wiring density of the constricted anti-fogging region 5 and the second anti-fogging region 4 is set so that the anti-fogging function can be maintained and heat is generated with a calorific value per unit area where the anti-fogging pattern is difficult to spread. .

  Specifically, in the second anti-fogging region 4, a wiring pattern is formed by a circular outline 42 forming an outline and a plurality of inclined lines 43 inside the outline. The plurality of rows of inclined lines 43 are connected to the contour line 42 at both ends. In the first anti-fogging region 3, a wiring pattern is formed by a circular contour line 32 that forms an outline and an inner line 33 that forms a lattice on the inside. Both ends of the inner line 33 are connected to the contour line 32. In the constricted anti-fogging region 5, a wiring pattern in which two heater wires 2 are arranged in parallel is formed. One end of the two heater wires 2 is connected to the contour line 42 of the second anti-fogging region 4, and the other end of the two heater wires 2 is connected to the contour line 32 of the first anti-fogging region 3. Yes.

  In the anti-fogging mirror 1 of the present embodiment having the above-described wiring pattern, as shown in FIGS. 4A to 4C, an anti-fogging pattern 6 such as an animal face and ear silhouette pattern is formed on the mirror surface.

(C) shows the anti-fogging pattern 6 in a state where further time has passed and the heat of the heater wire 2 has spread to the maximum. As shown in the figure, in this embodiment, an antifogging pattern 6 in which the space between the first antifogging region 3 and the second antifogging region 4 is constricted is formed on the mirror surface regardless of the passage of time.

  In the antifogging mirror 1 of the present embodiment configured as described above, the heat generation amount per unit area of the first antifogging region 3 is the heat generation amount per unit area of the second antifogging region 4 and the constriction antifogging region 5. Is bigger than. For this reason, the first anti-fogging region 3 is a portion having higher anti-fogging performance than the other anti-fogging regions 4 and 5 and is a portion suitable for the user to show a face.

  Here, the first anti-fogging region 3 has a large calorific value, but the second anti-fogging region 4 and the constricted anti-fogging region 5 have a small calorific value. Therefore, in the present embodiment, a characteristic ear portion appears clearly. An antifogging pattern 6 of an animal silhouette can be formed on the mirror surface.

  As described above, the antifogging mirror 1 of the present embodiment mirrors the antifogging pattern 6 of the animal silhouette in which the characteristic ear part appears clearly, after improving the antifogging performance of the part that reflects the user's face. It can be formed on the surface.
