Is provided in a state where the printed circuit board 22 provided with is supported by the upper substrate support portion 23 and the lower substrate support portion 24.

  Next, each electrical component disposed on the horizontally long rectangular printed circuit board 22 will be described below with reference to FIGS. Five detection bodies 30 for detecting capacitance are arranged in parallel in the front surface of the printed circuit board 22, and each detection body 30 is connected to a switch (not shown). Between the three detection bodies 30 on the left and the two detection bodies 30 on the right, there is a display 31 that displays the set temperature or current temperature of the freezer compartment 7 and the set temperature or current temperature of the refrigerator compartments 6 and 8. Arranged. That is, the respective display bodies 31 are attached to the printed circuit board 22 by the respective locking bodies 32 formed on the upper left and right lower end portions of the back surface being engaged with the engagement holes 33 formed on the printed circuit board 22. Will be described in detail.

  Lock holes 35 are formed in the printed circuit board 22 at the upper and lower positions of the detection bodies 30, and LEDs (Light Emitting Diodes) 36 as light sources are arranged at the upper and lower positions of the lock holes 35. Established. Each light guide 40 is fixed to the front position of each detection body 30 on the printed circuit board 22.

  The light guide 40 shown in FIG. 6 is made of a transparent synthetic resin material and has a generally hollow cylindrical shape, and the peripheral side wall 41 has an inner diameter and an outer diameter that extend outwardly toward the rear. A light introducing portion 42 that is formed and is a concave groove cut out in order to introduce light from the LED 36 corresponding to the LED 36 at a position opposed to the upper and lower portions of the rear end of the peripheral side wall 41 by 180 degrees. Further, the portion of the peripheral side wall 41 where the light introducing portion 42 is formed has the longest length in the front-rear direction, and gradually shortens so that the central portion between the two light introducing portions 42 is the shortest. Formed as follows. That is, the peripheral side wall 41 of the light guide 40 has the longest positions of 0 degrees at the top and 180 degrees at the bottom as viewed from the front, and the longest positions at 90 degrees on the right side and 270 degrees on the left side. Formed.

  Since the peripheral side wall 41 of the light guide 40 is formed in this way, when each LED 36 is lit, the illumination light is guided along the rear surface 41A of the peripheral side wall 41, and the inside of the peripheral side wall 41 is forward from the rear surface 41A. The light is transmitted and guided to the front surface 41B of the peripheral side wall 41, and the front surface 41B becomes bright and becomes a display surface.

  In addition, when the two LEDs 36 arranged in a small number are turned on, the portion of the rear surface 41A of the peripheral side wall 41 that is close to the LED 36 is farthest from the front surface 41B that is the display surface, and gradually increases as the distance from the LED 36 increases. Therefore, the amount of light reaches the front surface 41B uniformly, and there is no illumination unevenness and becomes uniform.

  In addition, a flange 44 having a square opening 43 formed at the front and rear intermediate positions is formed inside the peripheral side wall 41 of the light guide 40, and a locking body 45 is formed on each of the upper and lower flanges 44. The light guides 40 are attached to the printed circuit board 22 by fitting and locking the respective locking bodies 45 into the respective locking holes 35 formed and formed in the printed circuit board 22. A sponge-like conductive material 49 made of a conductive material is accommodated in the hollow portion of each light guide 40 attached to the printed circuit board 22, and the back surface of the conductive material 49 is disposed on the detection body 30 of the printed circuit board 22. The conductive material 49 is accommodated so as to be in contact with the front surface, and in contact with the rear surface of the glass 15 of the door body 10.

  The back surface of the transparent glass 15 of the door body 10 is painted black, but the front portion of the display 31, the annular portion around each conductor 49, and the front portions of LEDs 55 and 56 described later are Transparent without being painted. The operation portions 59A to 59E at the front positions of the respective conductors 49 corresponding to the respective light guides 40 are painted in black, and the operation portions 59A to 59E painted in black are provided with the operation portions 59A. Characters etc. meaning 59 through 59E are printed in white (see FIG. 10).

  That is, “ice making” for making ice with an ice making machine is provided in the leftmost operation portion 59A, and “freezing room 7” and “refrigeration chambers 6 and 8” are provided in the operation portion 59B adjacent to the right to “cool”. “Fast Freezing”, “Frozen” for setting the set temperature of the freezer compartment 7 in the operation unit 59C on the right side, and the refrigeration chambers 6 and 8 set in the operation unit 59D on the right side via the display 31. “Refrigeration” for setting the temperature and “interior light” for lighting the internal light are printed on the right-hand side (rightmost) operation unit 59E.

  As described above, each light guide 40 is disposed at the front position of each detection body 30 on the front surface of the printed circuit board 22, but the front portion of the display 31 of the glass 15 is transparent. The user can see and confirm the current temperature of the freezer compartment 7 and the current temperature of the refrigerator compartments 6 and 8 displayed on the display 31 through the 15 transparent portions.

  Here, for example, in order to set the temperature of the freezer compartment 7, the character display “freezing” displayed on the operation unit 59C displayed on the glass 15 is seen, and the operation unit 59C that is the third operation unit 59C from the left corresponding thereto is seen. When a finger touches the glass 15 in front of the conductor 49 in the light body 40, the detection body 30 detects a change in electrolytic capacity via the conductor 49, thereby closing the switch connected to the detection body 30. The set temperature is displayed in place of the current temperature of the freezer compartment 7, and when pressed for a long time, the preset temperature of the freezer compartment 7 is progressively incremented by 1 ° C in the range from minus 15 ° C to minus 21 ° C, and minus 21 When the temperature reaches to 15 ° C., the temperature returns to −15 ° C. and advances in the same manner. The set temperature is sequentially displayed on the left side of the display 31 and the set temperature when the long press is stopped is set. Equipment It is paid.

  Similarly, in order to set the temperature in the refrigeration chambers 6 and 8, the character display “refrigeration” displayed on the operation unit 59D displayed on the glass 15 is used, and the corresponding operation unit 59D from the left corresponds. When a finger touches the glass 15 in front of the conductive material 49 in a certain light guide 40, the detection body 30 detects a change in electrolytic capacity via the conductive material 49, so that a switch connected to the detection body 30 is switched. The set temperature is displayed in place of the current temperature of the refrigerator compartments 6 and 8 when closed, and when the button is held down, the preset temperature of the refrigerator compartments 6 and 8 is incremented by 1 ° C. from 2 ° C. to 10 ° C. When the temperature reaches 0 ° C., the temperature returns to 2 ° C. and advances in the same manner. The set temperature is sequentially displayed on the right side of the display 31 and the set temperature when the long press is stopped is set. Stored in

  When the user's finger touches the operation unit 59C and the switch is closed as described above, the two LEDs 36 corresponding to the third light guide 40 from the left are lit, and the illumination light Is guided along the rear surface 41A of the peripheral side wall 41, and is transmitted forward through the peripheral side wall 41 from the rear surface 41A, and is guided to the front surface 41B of the peripheral side wall 41, and the front surface 41B serving as a display surface becomes brighter. Thus, it can be understood which operation unit has been operated. At this time, the portion near the LED 36 on the rear surface 41A of the peripheral side wall 41 is farthest to the front surface 41B which is the display surface, and gradually approaches the front surface 41B as the distance from the LED 36 increases. That is, there is no illumination unevenness and it is uniform.

  As described above, the area including the characters “frozen” displayed on the glass 15 in front of the conductive material 49 in the third light guide 40 from the left serves as the operation unit 59C, and the third light guide. The two LEDs 36 corresponding to the body 40 are turned on, and light reaches and illuminates the front surface 41B of the light guide 40. However, the light guide 40 is not limited to the third light guide 40 from the left. Can be illuminated as well.

  Reference numeral 50 denotes a light shielding body having a rectangular tube shape, and four side surfaces serve as light shielding walls, and are attached to the printed circuit board 22 so as to cover the periphery of the second light guiding body 40 from the left. That is, each light blocking body 51 formed in the center of the rear surface of the upper and lower walls of the light blocking body 50 is locked in the locking groove 52 and the locking hole 53 formed in the printed circuit board 22, thereby The body 50 is attached to the printed circuit board 22. Therefore, even if any of the three light guides 40 is illuminated by covering the middle light guide 40 of the three light guides 40 arranged side by side with the light shield 50, the other light guides Since light does not reach 40 and is reliably shielded, it is possible to reliably grasp which operation unit has been operated.

  Further, a door heater, which is a transparent film heater that generates heat when energized, is adhered to the front surface of the glass 16 in the middle of the door body 10 to prevent dew from adhering to the door body 10, An LED 55 that is turned on when the door heater is energized and an LED 56 for displaying a child lock state are attached to the printed circuit board 2 between the right two detection bodies 30 up and down.

  Reference numeral 66 denotes a light-shielding body composed of two cylindrical bodies 66A and 66B which have a shape of 8 in front view. The two cylindrical bodies 66A and 66B serve as light-shielding walls, and are printed so as to cover the LEDs 55 and 56 from the front. Attached to the substrate 22.

  That is, the light blocking body 58 is formed by locking the locking bodies 58 formed on the upper rear surface of the cylindrical body 66A and the lower rear surface of the cylindrical body 66B in the locking holes 57 formed on the printed circuit board 22. 66 is attached to the printed circuit board 22. Therefore, the light from the right two light guides 40 can be shielded, and when the LEDs 55 and 56 are turned on, this illumination light can be directed to the front without being released sideways. It is possible to reliably grasp whether the light has been lit.

  Here, the display 31 that displays the set temperature or the current temperature of the freezer compartment 7 and the set temperature or the current temperature of the refrigerator compartments 6 and 8 will be described in detail with reference to FIGS. First, the display 31 is roughly divided into a display main body 70 in which a locking body 32 is formed on the left and right upper and lower ends of the back surface, and a plurality of LEDs 71 as a light source attached to the surface, and the display main body. The LED attachment body 72 is attached to the back surface of the display 70, and the display plate 73 is attached to the surface of the display body 70.

  In this embodiment, the LED 71 is mounted on the surface of the LED mounting body 72, but a mounting hole or mounting groove is formed on the surface of the LED mounting body 72, and the LED 71 is housed and mounted in the mounting hole or mounting groove. May be.

  First, a concave groove 75 for accommodating the LED attachment body 72 is opened on the back side of the display body 70, and the concave groove 75 is opened at substantially the same depth as the thickness of the LED attachment body 72. When the LED mounting body 72 is adhered to and stored in the surface forming the concave groove 75, it is flush with the back surface.

  In addition, as shown in FIG. 7, there are two attachment holes 76 of seven segments constituting one number on the left side of the display body 70 in order to display the set temperature or the current temperature of the freezer compartment 7. Two mounting holes for displaying the set temperature or the current temperature of the refrigerator compartments 6 and 8 on the right side, and one mounting hole for displaying a character meaning “minus” on the left side of the two mounting holes 76 on the left side. Four mounting holes 76 for expressing the meaning of temperature “° C.” are opened on the right side of 76 and the left two mounting holes 76, and the temperature “° C.” is placed on the right side of the two left mounting holes 76. The four attachment holes 76 for expressing the meaning of "are opened.

  In this case, except for the mounting hole 76 of “°” representing the degree of “° C.”, the other mounting holes 76 are gradually shortened in the longitudinal or longitudinal direction from the front toward the rear toward the center. To form. Therefore, as shown in FIG. 7, although not continuous (because it is a segment), the left part of the display unit 70 before assembly is “−88 ° C.” and the right part is “88 ° C.”. Looks like.

  Further, when the LED attachment body 72 is attached to the concave groove 75 on the back surface side of the display device main body 70, each LED 71 is fitted into the attachment hole 76 from behind and stored. That is, except for the mounting hole 76 of “°”, the rear opening of the other mounting holes 76 has almost the same area as the LED 71, and the rectangular front opening has an area slightly larger than three times that of the LED 71. As described above, the other mounting holes 76 are formed such that the longitudinal or longitudinal direction is gradually shortened toward the center, that is, each LED 71 from the front to the rear. Then, a light guide body 77 having approximately the same volume as the mounting hole 76 is fitted and stored in each mounting hole 76.

  In other words, it has a rear opening that is substantially the same area as the LED 71 and a front opening that is larger than the LED 71 so that the horizontal or vertical longitudinal direction gradually increases from the center toward the outside from the rear to the front. The attachment holes 76 of seven segments constituting one number are formed, and a light guide 77 having substantially the same volume as the attachment holes 76 is fitted and accommodated in the attachment holes 76. Therefore, only one LED 71 is required for one segment constituting one number, and the temperature can be enlarged and displayed.

  The display plate 73 attached to the surface of the display main body 70 is a synthetic resin film having a light shielding portion 79 and a light transmitting portion 80. That is, as described above, the left portion of the display main body 70 is seen as “−88 ° C.”, and the right portion as “88 ° C.”, but 45 × 5 × 9 corresponding to each letter or number. A translucent part 80 having the same size as that of the LED 71 is formed via a light shielding part 79 having a short width.

  Therefore, since the display 31 is configured as described above, the set temperature and the current temperature of the freezer compartment 7 are displayed on the left side of the display 31. That is, since the necessary LED 71 is lit to display the set temperature of the freezer compartment 7 and the like, the left portion of the display plate 73 is passed through the light guide body 77 and the light transmitting portion 80 of the display body 70 in front of the LED 71. The set temperature etc. will be displayed brightly.

  Similarly, the set temperature and the current temperature of the refrigerator compartments 6 and 8 are displayed on the right side of the display 31. That is, since the necessary LEDs 71 are lit to display the set temperatures of the refrigerator compartments 6 and 8, etc., the display plate 73 of the display plate 73 is connected via the light guide body 77 and the translucent portion 80 of the display body 70 in front thereof. The set temperature etc. will be displayed brightly on the right.

  In this case, in the case of 7-segment display with LEDs, conventionally, a plurality of LEDs had to be used for one segment. However, according to the present embodiment, one LED performs the same function as three LEDs. Therefore, an extremely inexpensive display device can be provided.

  According to this embodiment, one LED 71 is displayed for each component of a number or character to display one number or character. However, in order to display a large number or character, the number or character is displayed. This can be dealt with by enlarging and displaying two or more LEDs 71 per component, but even in this case, since the number of LEDs 71 is as small as possible, an extremely inexpensive indicator and cooling provided with this indicator A storage can be provided. Furthermore, it is applicable not only to a cooling storage but also to an air conditioner such as an air conditioner and other electrical products.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
