Description

  The present invention relates to a small electric device such as an electric razor, an electric toothbrush, a hand-held massager, etc., and is an improvement of the structure of a light emitting display portion provided in a main body case of the small electric device.

  This type of light-emitting display unit can be seen, for example, in the electric razor of Patent Document 1. In this case, a light-emitting display unit is provided on the front surface of the main body case that also serves as a grip. The light-emitting display unit is composed of an LED mounted on a circuit board, a light guide window provided on the main body case, and the like. The circuit board is disposed on the inner surface of the front wall of the main body case, and is fixed to the inner frame together with the secondary battery disposed on the rear surface. The circuit board is equipped with switches, a control circuit for controlling the operating state, a charge control circuit, LEDs for light emission display, etc. In many cases, all electronic components and switches are integrated on one board.

Japanese Patent No. 4341887 (paragraph number 0025, FIG. 4)

  In recent years, a surface-mounted chip LED is often used as a light source of a light-emitting display unit, and this type of LED is soldered in a state where a flat surface of a rectangular chip is in close contact with the surface of a circuit board. . As described above, the chip LED fixed in close contact with the substrate surface emits light in a direction orthogonal to the substrate surface, and therefore there is no choice in the arrangement form of the circuit board with respect to the main body case. I had to do it. For example, when the light emitting display portion is provided on the front surface of the main body case, the circuit board has to be arranged in parallel with the front surface of the main body case. Of course, the circuit board can be arranged in a state orthogonal to the front surface of the main body case. However, in that case, the light emitting display section is provided on the side surface of the main body case, and the usability is deteriorated.

  As described above, the fact that there is no room for selection in the circuit board arrangement form is a great limitation in determining the appearance design of the main body case. Since many electronic components and switches are collectively arranged on the circuit board, the vertical and horizontal dimensions cannot be reduced unnecessarily. For this reason, when determining the left-right width and the external shape of the main body case, it is a major premise to secure a space for accommodating the circuit board, which hinders the degree of freedom in design. By providing a plurality of circuit boards and disposing them in the main body case, it is possible to expand the range of selection when determining the left-right width and appearance of the main body case. However, since it is necessary to provide a fixing structure for each individual substrate and to connect the substrates together, it is inevitable that a lot of labor is required for assembly and the manufacturing cost of the small electric device increases.

  The object of the present invention is to make it possible to more freely arrange the circuit board while effectively using the space in the main body case, and to further improve the degree of freedom of the external design of the main body case without being restricted by the circuit board. To provide electrical equipment.

In the small electric apparatus according to the present invention, the light emitting display unit 30 is provided on the front surface of the main body case 1. The width dimension in the front-rear direction of the main body case 1 is set larger than the width dimension in the left-right direction. Housed in the main body case 1 are two batteries 17 for supplying electric power to the operating portion 11 of the small electric device, the circuit board 18, and a battery holder 16 for supporting both 17 and 18. The light emitting display unit 30 includes light emitters 31 to 34 mounted on a flat circuit board 18 housed inside the main body case 1. As shown in FIG. 1, the circuit board 18 is arranged in parallel with a vertical plane P passing through the left and right center of the main body case 1. The light emitters 31 to 34 are mounted on the front edge portion of the circuit board 18 with the light emitting surface 38 facing the front surface of the main body case 1, and the light emitting surface 38 faces the light incident surface 46 of the light guide 35. . The two batteries 17 are arranged in an obliquely adjacent state in the front-rear direction. Light emitting bodies 31 to 34 are arranged between the battery 17 on the front side and the circuit board 18 . As the light emitters 31 to 34, various kinds of LEDs (light emitting diodes), a small halogen bulb, a nipple bulb, or the like can be applied. In addition, the main body case 1 in the present invention is a concept including the main body case 1, a decorative cover 13 fixed to the case 1, a switch panel, and the like.

  Inside the main body case 1, a battery 17 for supplying power to the operating unit 11 of the small electric device, a circuit board 18, and a battery holder 16 that supports both 17 and 18 are accommodated. A plurality of light emitters 31 to 34 are mounted on the circuit board 18 in rows at predetermined intervals. A light shielding wall 36 that prevents light leakage between the adjacent light emitters 31 to 34 is formed integrally with the battery holder 16.

  The circuit board 18 whose vertical dimension is larger than the width dimension is supported by the battery holder 16 in a vertically long posture. A plurality of light emitters 31 to 34 are mounted in the middle part of the circuit board 18 in the vertical direction. The upper and lower ends of the circuit board 18 and the middle part in the vertical direction are supported by the mounting parts 24 and 25 provided in the battery holder 16 and the board receiving part 50 provided in the light shielding wall 36.

  In the small electric apparatus according to the present invention, the light emitting display unit 30 is configured with the light emitters 31 to 34 mounted on the circuit board 18 as main components. In addition, the circuit board 18 is arranged in parallel with the vertical plane P passing through the center of the left and right sides of the main body case 1 so that the left and right width of the front surface of the main body case 1 is not affected by the size of the circuit board 18. Further, the light emitters 31 to 34 are mounted on the front edge portion of the circuit board 18, and the light emitting surface 38 is directed toward the front surface of the main body case 1 so that light emission display can be performed on the front surface of the main body case 1. . Therefore, according to the small electric device of the present invention, the degree of freedom of the arrangement form of the circuit board 18 can be improved while effectively using the space in the main body case 1, and the appearance design of the main body case 1, particularly the design of the front surface of the case. The degree of freedom can be improved and the appearance of small electrical equipment can be diversified.

  If the battery 17 and the circuit board 18 are supported by the battery holder 16 and the light shielding wall 36 provided in the holder 16 prevents light leakage between the adjacent light emitters 31 to 34, the display by the light emitting display unit 30 is misidentified. It can be clarified in the state without the room to do. Further, by forming the light shielding wall 36 integrally with the battery holder 16, it is possible to prevent an increase in the number of components of the light emitting display unit 30, and to reduce the cost of a small electric device including the light emitting display unit 30.

  When the upper and lower ends of the vertically long circuit board 18 and the middle part in the vertical direction are supported by the mounting parts 24 and 25 provided in the battery holder 16 and the board receiving part 50 provided in the light shielding wall 36, a circuit is obtained. The substrate 18 can be firmly fixed in a state in which it cannot move in the front-rear, left-right, and up-down directions. Therefore, it is possible to reliably prevent the circuit board 18 from dropping from the battery holder 16 due to a drop impact or changing the mounting posture with respect to the battery holder 16, thereby improving reliability during long-term use. There is also an advantage that the light emitting surface 38 of the light emitters 31 to 34 protruding from the front edge of the circuit board 18 can be protected by the light shielding wall 36.

The display surface 47 of the light guide 33 is exposed to the outer surface of the main body case 1 through a display opening 49 opened in the main body case 1 and the decorative cover 13. The display opening 49 is formed on the right side of the left and right center of the main body case 1.

  The light shielding wall 36 is a rectangular wall surface projecting rightward from the front part of the front side wall 29 constituting the previous partition wall 23, and contacts the circuit board 18 at the upper and lower centers of the adjacent parts of the chip LEDs 31 to 34. Thus, light leakage between the chip LEDs 31 to 34 is prevented (see FIG. 7). The light receiving wall 36 is used to provide a board receiving portion 50 that supports the upper and lower middle portions of the circuit board 18. The board receiving part 50 is composed of an L-shaped cutout formed over the protruding end of the light shielding wall 36 and a protrusion protruding further outward from the protruding end, and includes a front peripheral surface of the circuit board 18 and a front periphery. The left side surface continuous with the surface is received to prevent the circuit board 18 from being bent and deformed in the thickness direction.

  The circuit board 18 is assembled to the battery holder 16 as follows. The circuit board 18 is fixed to the battery holder 16 in a vertically long posture in a state parallel to the vertical plane P (see FIG. 1) passing through the left and right center of the main body case 1 and adjacent to the right outer side of the secondary battery 17. For positioning at the time of fixing, a positioning groove 51 is formed in the front and rear center of the upper edge of the circuit board 18, and a positioning groove 52 and a positioning step 53 are provided in the front and rear center of the lower edge of the circuit board 18.

  As shown in FIGS. 5 and 6, the upper mounting portion 24 of the battery holder 16 is formed with a positioning protrusion 55 that engages with the previous positioning groove 51. An elastic claw 56 that engages and captures the upper end wall 21 is formed integrally. The lower mounting portion 25 is formed with a loading groove 57 that receives the lower edge of the circuit board 18 and a positioning projection 58 that engages with the previous positioning groove 52. The positioning protrusion 58 is formed in a state crossing the groove in the front and rear halfway of the loading groove 57.

  With the positioning groove 52 of the circuit board 18 engaged with the positioning protrusion 58 of the lower mounting portion 25 and the lower edge of the board fitted into the loading groove 57, the upper edge of the circuit board 18 is shown by an imaginary line in FIG. As shown, the circuit board 18 can be engaged with the upper mounting portion 24 and fixed to the battery holder 16 by being pressed against the inclined surface of the elastic claw 56. In this state, the positioning groove 51 on the upper side of the circuit board 18 is engaged with the positioning protrusion 55. The positioning step portion 53 is received by the front end surface of the lower mounting portion 25 (see FIG. 6), and the upper and lower middle portions of the circuit board 18 are received by the substrate receiving portion 50. Therefore, the circuit board 18 is fixed so as not to move forward and backward, left and right, and up and down.

  As described above, after the battery holder 16 to which the circuit board 18 and the secondary battery 17 are assembled is accommodated in the inner case 15, the screws 61 inserted from the outer surface of the bottom wall of the inner case 15 are inserted into the screw bosses 26. The battery holder 16 is integrated with the inner case 15 by being screwed into the inner case 15. After that, by loading the light guide 35 into the loading hole 48 of the inner case 15, the light emitting surface 38 of each of the chip LEDs 31 to 34 is slightly spaced from the light incident surface 46 of each of the light guiding walls 41 to 44. Face up in between. In the state in which the battery holder 16 is integrated with the inner case 15, the lower peripheral wall of the case packing 62 fixed to the lower end of the motor holder is fixed between the upper end wall 21 and the opening inner edge of the inner case 15 ( (See FIG. 4). Finally, the main body case 1 is assembled to the inner case 15.

  As described above, when the circuit board 18 is arranged in parallel with the vertical plane P passing through the left and right center of the main body case 1, it is possible to avoid an increase in the right and left width of the main body case 1, particularly the grip portion. Further, the circuit board 18 can be arranged by effectively utilizing the space on the right side of the secondary battery 17 that can be formed when the secondary battery 17 is arranged obliquely adjacent in the front-rear direction. Therefore, the degree of freedom in the appearance design of the main body case 1 can be improved without being restricted by the circuit board 18, and the case appearance and the case structure that could not be employed in the conventional circuit board arrangement structure can be selected. It is possible to In addition, although the circuit board 18 is arranged in parallel with the vertical plane passing through the left and right center of the main body case 1, the electronic parts and the switches 12 are arranged on the circuit board 18 in a concentrated manner, so that assembly can be performed with less effort. Can be done.

  When using the electric razor, if the switch knob 5 is slid upward to switch the switch 12 to the ON state, the chip LEDs 31 to 34 emit light according to the voltage of the secondary battery 17 at that time, and the secondary battery 17 Displays the charge status (remaining amount). For example, in a state where the secondary battery 17 is fully charged, the four chip LEDs 31 to 34 emit light, indicating that the state of the battery is appropriate. When the secondary battery 17 is less than the predetermined voltage value, the uppermost chip LED 31 stops emitting light, and the second and third chip LEDs 32 and 33 are gradually reduced as the voltage value gradually decreases. Are stopped in order. In a state where only the lowermost chip LED 34 emits light, the chip LED 34 is blinked to indicate that the secondary battery 17 is in a state to be charged, thereby alerting the user.

  Each chip LED 31-34 can be set to the following light emission display state. The third chip LEDs 31 to 33 counted from the upper side are used for the remaining amount display of the secondary battery 17 similar to the above, and the lowermost chip LED 34 is used when the secondary battery 17 is being charged. Only emit light and stop emitting light when the battery is fully charged. In the case of performing light emission display with the two chip LEDs 31 and 32, for example, the upper chip LED 31 can function as a pilot lamp, and the lower chip LED 32 can function as a charge lamp. The light emission colors of the four chip LEDs 31 to 34 may be the same, but the light emission colors of the chip LEDs 31 to 34 can be made different to give meaning to the color of the emitted light.

  In the above embodiment, the secondary battery 17 is disposed obliquely adjacent in the front-rear direction, and the adjacent circuit board 18 is disposed on the side surface thereof, but this is not necessary. For example, as shown in FIG. 10, two secondary batteries 17 can be mounted adjacent to the battery holder 16 on the left and right sides, and a circuit board 18 can be disposed between the batteries 17. In this case, the circuit board 18 is arranged along a vertical plane P passing through the center of the left and right sides of the main body case 1. The battery holder 16 is integrally provided with a light shielding wall 36 that prevents light leakage between the respective chips LEDs 31 to 34.
