The refrigerator main body 1 has a refrigerating chamber 2d, a freezing chamber 4d1, a vegetables room 5d, and the like in order from the top. A quenching chamber 4d2 is provided between the refrigerating chamber 2d and the freezing chamber 4d1 and an ice making chamber 4d3 is provided beside the quenching chamber 4d2.

A door for opening and closing the front opening is provided in the front opening of each storage room. That is, the left refrigerating chamber door 2a and the right refrigerating chamber door 2b are provided in the front opening of the refrigerating chamber 2d and the freezing chamber 4d1, the quenching freezing chamber 4d2, the ice making chamber 4d3, The freezing chamber door 4b, the quenching freezing chamber door 4c, the ice making chamber door 4a, and the vegetable chamber door 5 are provided at the front opening of the refrigerator compartment.

The left refrigerator compartment door 2a and the right refrigerator compartment door 2b are rotatably supported by the upper hinge 3 (the left hinge 3a and the right hinge 3b) provided on the upper portion of the refrigerator main body 1, . That is, a so-called French door composed of left and right hinges is constituted.

In addition, the freezing chamber door 4b, the quenching chamber door 4c, the ice making chamber door 4a, and the vegetable chamber door 5 can be taken out together with the containers of the respective storage chambers as drawer doors.

The left and right refrigerator compartment doors 2a and 2b, the freezing compartment door 4b, the freezing compartment compartment door 4c, the ice-making compartment door 4a and the vegetables compartment door 5 are provided with glass plates (6a) are provided.

As shown in Fig. 4, the foamed heat insulating material 7 is filled and foamed between the door front plate (door front member) 6 formed of the glass plate 6a and the door inner plate 8. [ The thickness of the glass plate 6a, which is the door front plate 6, is 2 mm to 3.5 mm in the present embodiment. The thickness of the glass plate 6a is such that the glass plate 6a is not broken or cracked due to impact generated when the refrigerator is assembled, when the refrigerator is transported, and when the refrigerator is used.

Further, in the case where the strength is further secured or the plate thickness is made thin, the glass plate 6a may be subjected to heat strengthening treatment, chemical strengthening treatment or the like. The glass plate 6a is an insulator.

Next, in Fig. 1 and Fig. 2, reference numeral 9 denotes an operation unit. The operation unit 9 is provided for setting the room temperature of each storage room such as the refrigerating compartment 2d and the freezing compartment 4d1 by operating the user from the outside or rapidly cooling the refrigerating compartment 2d or the freezing compartment 4d1, Or rapid deicing. In addition, it is installed in the refrigerating compartment 2d to regulate the temperature of the storage compartment (not shown) which keeps the stored food in a reduced pressure or in a low oxygen state, Setting. That is, the user can operate the operation unit 9 to set various functions of the refrigerator.

Reference numeral 10 denotes a display unit. The display unit 10 displays the result of the input from the operation unit 9 on the outside of the refrigerator main body 1. Thereby, the user can confirm the operation performed by the operation unit 9 or check the state of the previously set all functions.

The operating section 9 and the display section 10 are not provided with a special panel but are provided on the glass plate 6a. That is, the glass plate 6a provided on the left refrigerating chamber door 2a is provided so as to be flat over the entire outer surface of the left refrigerating chamber door 2a including the operating portion 9 and the display portion 10. [

In other words, the operating section 9 and the display section 10 are directly provided on the door front plate 6 which is the glass plate 6a. Therefore, the conventional operation panel is omitted.

Reference numeral 9a denotes a display touch unit for displaying the operation unit 9 and the display unit 10 by lighting them. By operating the display touch unit 9a, the operation unit 9 and the display unit 10 are turned off To the lighting state shown in Fig. That is, when the user presses the touch portion 9a for display (e.g., a character display mark of " MENU "), touches the touch portion 9a, The characters and symbols of the operation section 9 and the display section 10 of the display section 10 are switched from the unlit state to the lit state and displayed on the glass plate 6a and the operation section 9 can be operated. Accordingly, the display of characters, figures, and the like that can be visually recognized at normal times becomes only the display touch portion 9a, and when the operation portion 9 and the display portion 10 are not lighted, the appearance can be made simple, . Further, since the operation section 9 and the display section 10 are turned ON only when necessary, an energy saving effect can be obtained.

When the display touching portion 9a is operated, characters, figures, etc. of the entire operating portion 9 and the display portion 10 are lit up and displayed. After the elapse of the predetermined time (for example, about 0.1 to 1.0 second), the display section 10 displays only the display indicating the setting state of the currently set all-purpose function, and the other displays are turned off. When the non-operation state has elapsed for a predetermined time (for example, 1 minute to 3 minutes), all the characters, figures, and the like of the operation unit 9 and the display unit 10 are turned off, and only the display touch unit 9a is visible. As described above, after all the character or the like is lighted and displayed once after operating the normally-recognizable display touching portion 9a, the user can confirm the function of the refrigerator and what can be changed and set.

The back surface of the glass plate 6a is coated with a colored paint. As a result, the foam insulator 7 is treated so as not to be seen from the front side, and the operation portion 9 and the display portion 10 are clearly visible by the operation of the display touch portion 9a. .

Next, the operation unit 9 and the display unit 10 will be described in more detail with reference to Fig.

2, characters (power saving, freezing, refrigerating, icing, cooling mode, vacuum chilled letters) and figures of the operating portion 9 surrounded by broken lines are displayed on a film (Hereinafter, referred to as a translucent character) that is obtained by partially subtracting the color of the glass plate 6a and is displayed on the front surface of the glass plate 6a only when an LED (light emitting diode) or the like on the substrate . The display touch portion 9a is directly printed on the back surface of the glass plate 6a. The operating portion 9 refers to a front face (that is, the front face side of the glass plate 6a) at a position facing the face on which the character portion is formed. Examples of means for providing the display touch portion 9a on the back surface of the glass plate 6a include etching and inlaid, in addition to printing.

In Fig. 2, the portion surrounded by the solid line is the display unit 10 that indicates the set state of the various functions in accordance with the input by the operation of the operation unit 9 described above. Then, the characters (such as "electric power take-out", "water supply", "going out, power saving", "strong, medium and weak", "rapid deicing, Quot ;, " greenhouse steel ", " ice-on-the-chill ", etc.) and the like are translucent characters displayed by partially subtracting the color of the film 16 as in the operation section 9, Is displayed on the front surface of the display unit 6a and can be recognized.

The film 16 is attached to the rear surface of the glass front plate 6a, which is the door front plate 6, so as to be extremely close to or close to the rear surface. Therefore, after the display touch portion 9a is operated, the character display can be clearly confirmed from the front surface of the left refrigerating chamber door 2a through the glass plate 6a. That is, the door has a high visibility and a flat glass plate, and has an excellent external appearance.

Further, the operating section 9 and the display section 10 are installed vertically as shown in Fig. The display unit 10 is configured to display the function of the refrigerator main body 1, such as the fact that rapid cooling or quasi-refrigeration is in operation.

The character display of the display unit 10 is configured to be illuminated by an LED (light emitting diode) or the like on a substrate to be described later and projected to the front surface of the glass plate 6a to be exposed.

3, reference numeral 11 denotes a cover provided on the side surface of the left refrigerating chamber door 2a. The lid 11 is provided on the half hinge side of the left refrigerating chamber door 2a and is provided between the right side refrigerating chamber door 2b and the adjacent right refrigerating chamber door 2b. In this configuration, when the left refrigerating chamber door 2a and the right refrigerating chamber door 2b are closed, the lid 11 is not visible from the user.

Next, in Fig. 4, reference numeral 6 denotes a door front plate, 7 denotes a foam insulating material, 8 denotes a door inner plate, and 12 denotes a substrate assembly. The substrate assembly 12 includes a light emitting unit 34 for an operation unit for displaying the light emission of the operation unit 9, a light emitting unit 13 for a display unit for displaying the light emission of the display unit 10, (Not shown) including a light shielding unit 35 for shielding and shielding light, a detection unit 14 for detecting a change in capacitance, a determination unit (not shown), and an automatic control unit A film 16 partially provided with a translucent character or figure or the like, a substrate case 17, and the like. In this embodiment, the light emitting means 34 for the operating unit and the light emitting means 13 for the display unit are collectively referred to as light emitting means.

The light-emitting unit 34 for the operating unit has an LED 34a for the operating unit provided on the front surface of the substrate 15. [ The front surface of the detecting section 14 has a transparent or semitransparent operating portion light guiding portion (first light guiding means) 34b for diffusing light from the operating portion LED 34a.

The light emitting means 13 for the display unit has a display portion LED 13a provided on a surface opposite to the light emitting means 34 for the operating portion, that is, on the back surface of the substrate 15. [ And a light guiding portion (second light guiding means) 13b for a display portion which is transparent or semitransparent for guiding the light from the LED 13a for the display portion from the back surface side of the substrate 15 to the front surface side.

The material of the light guide portion 34b for the operating portion and the light guiding portion 13b for the display portion may be transparent or translucent, such as resin or glass.

One surface of the substrate 15 (including the detecting portion 14) is covered with a film (front surface member) 16 and the other surface is covered with a substrate case 17. [

The film 16 is provided in close contact with or close to the front surface of the light guiding portion 34b and the light shielding means 35 for the operating portion. The film 16 is configured to transmit light from the light emitting means 34 for the operating portion and the light emitting means 13 for the display portion from the back surface to the whole surface and transmit the light to the glass plate 6a side. In addition, the film 16 may be thin as in the form of a film or a sheet, and may transmit light through an uncoloured portion or a light colored portion.

The detecting unit 14 is paired with the operating unit 9 when assembled to the left refrigerating chamber door 2a. That is, as shown in Fig. 4, the operation section 9 is arranged on the front surface side so as to overlap the detection section 14 on the back side via the glass plate 6a, the film 16, and the light guide section 34b for the operating section, do.

The determination unit (not shown) detects a change in capacitance between the operation unit 9 and the detection unit 14 in the substrate 15. [ And includes an oscillation circuit whose oscillation and amplitude change in accordance with the change of the capacitance when there is a change in the capacitance. Thereby, the automatic control unit which takes out the switch signal and the on / off signal outputted by the judging unit drives the load. Further, by the operation of simply passing the user in front of the operating portion 9 or by wiping the front surface (left fridge door 2a) of the refrigerator for cleaning by the user, the switch signal and the on / It is configured not to be.

The glass plate 6a constituting the door front plate 6 is an insulator and a transparent plate material. When the display touching portion 9a is operated to make the entire surface of the glass plate 6a as the operating portion 9, it is possible to display the film 16 placed on or in contact with the back surface of the operation portion 9 of the glass plate 6a Characters (or graphic symbols) are illuminated on the entire surface of the glass plate 6a by the light emitting means to display the operation contents of the operation unit 9. [

A detecting section 14 provided on the substrate 15 and connected to the judging section is attached to the glass plate 6a through the film 16 and the light guiding section 34b for the operating section on the back surface of the glass plate 6a opposed to the operating section 9 As shown in FIG. A character or graphic symbol of the display unit 10 provided in parallel with the operation unit 9 is illuminated by a film 16 covering the surface of the substrate 15 so as to be projected onto the entire surface of the glass plate 6a Is displayed.

The display of the characters (or graphic symbols) of the display unit 10 is specified by irradiating from the back surface with the display unit light emitting means 13 provided on the substrate 15. [ When a hand or a finger touches the operation section 9, the detection section 14 on the substrate 15 senses a change in capacitance between the detection section 14 and the glass plate 6a and notifies the judgment section on the substrate 15 do. When the determination unit detects the input, the load is operated through the automatic control unit.

Here, the load operated through the automatic control unit refers to the forced continuous operation of the refrigeration cycle, the forced continuous operation of the cool air circulation fan (not shown), or the forced "open" control of the damper for controlling the cold air supply amount to be. By controlling these loads, the refrigerating compartment 2d is rapidly cooled or the freezing compartment 4d1 is rapidly cooled and frozen.

4, reference numeral 18 denotes a case cover. The case cover 18 serves to isolate the substrate assembly 12 from the foam insulation 7. The film 16 on the surface of the substrate 15 serves to hold the substrate assembly 12 in the case cover 18 so as to come close to or close to the glass plate 6a which is the door front plate 6.

4 and 5 show a colored paint layer 19 having a light-transmitting property painted on the back surface of the glass plate 6a. The colored coating layer 19 is provided over the entire back surface of the glass plate 6a.

19a is a protective film. The protective film 19a protects the glass plate 6a from being scattered around even when a large impact is applied to the glass plate 6a to cause breakage or cracking of the glass. The protective film 19a is adhered to the same surface as the colored paint layer 19. As a result, the appearance of the foam insulator 7 is prevented from being impaired from the front side of the door by damaging the appearance.

In addition, the width direction of the substrate assembly 12 and the width direction of the glass plate 6a are disposed so as to intersect with each other. This is due to the property that the twist of the glass plate 6a tends to appear in the longitudinal direction when the heat treatment is applied to the glass plate 6a. That is, in consideration of this property, the influence of twisting of the glass plate 6a when the substrate assembly 12 is installed is suppressed.

When the glass plate 6a is assembled along the longitudinal direction of the glass plate 6a along the longitudinal direction of the glass plate 6a, the glass plate 6a and the detection unit 14 A gap is likely to be generated. This causes a problem that the input contents from the operating unit 9 are not transmitted to the detecting unit 14 well.

Therefore, in the present embodiment, the longitudinal direction of the substrate assembly 12 is disposed in a direction crossing the longitudinal direction of the glass plate.

The opaque paint layer 19b is painted on the back surface of the colored paint layer 19 (on the side of the foam insulating material 7) to prevent the foamed heat insulating material 7 from being seen from the front side of the door, 19 are suppressed and the appearance of the color is stabilized. The opaque paint layer 19b and the colored paint layer 19 are of the same color and opaque with a color tone equal or darker than that of the colored paint layer 19.

The opaque paint layer 19b is not provided on the projection surface of the operation portion 9 and the display portion 10 displayed on the film 16 such as characters or figures. More specifically, the opaque paint layer 19b provided on the back surface of the colored paint layer 19 is not applied to the areas corresponding to the operation section 9 and the display section 10, and instead the operation section 9 and the display section 10 Is coated with a transparent clear layer 19c. At this time, the end of the clear layer 19c overlaps with the end of the opaque paint layer 19b.

A protective film 19a is provided on the back of the opaque paint layer 19b to avoid the area corresponding to the operating section 9 and the display section 10. [ At this time, the end of the protective film 19a overlaps with the end of the clear layer 19c.

That is, in the region of the glass plate 6a where the operating section 9 and the display section 10 are displayed, the colored paint layer 19, the clear layer 19c, and the protective film 19a are formed in this order. The area where the operation section 9 and the display section 10 are not displayed is composed of the colored paint layer 19, the opaque paint layer 19b and the protective film 19a in this order.

The characters and figures of the operation section 9 and the display section 10 displayed on the film 16 covering the entire surface of the substrate 15 are placed close to or close to the back surface of the clear layer 19c. In other words, the opaque paint layer 19b is located outside the front projection position of the operation section 9 and the display section 10 displayed on the film 16, and the opaque paint layer 19b is located at the front projection position of the operation section 9 and the display section 10, And a clear layer 19c on the back side of the paint layer 19 and the colored paint layer 19. [ With this configuration, it is possible to prevent the glass plate 6a from being damaged when the film 16 and the substrate 15 are assembled to the back surface of the glass plate 6a.

With this configuration, characters, figures, and the like of the operating section 9 and the display section 10 are not displayed while the light emitting section 34 for the operating section and the light emitting section 13 for the display section are not emitting light, The color of the colored paint layer 19 is displayed on the front surface of the screen. It is possible to prevent the letters 9 and the characters and figures of the display unit 10 and the foamed thermal insulating material 7 from being seen through and to improve the appearance designability of the operation unit 9 and the display unit 10 during non-display.

In addition, the color of the opaque paint layer 19b and the color painted on the entire surface of the film 16 were made a winter color. The opaque paint layer 19b applied to the backside of the colored paint layer 19 is not partially applied to illuminate the operating section 9 and the display section 10 for emitting light, Respectively. At this time, when the color of the opaque paint layer 19b and the color of the front surface of the film 16 are different from each other or extremely different in shade, the color tone of the opaque paint layer 19b is different from that of the film 16, The front surface of the door may be seen through the front surface of the door.

Therefore, the color of the opaque paint layer 19b and the color of the front surface of the film 16 are made the same color so as to unify the hue of each other, so that the appearance is not conspicuous and the appearance designability is improved.

In the present embodiment, the colored paint layer 19, the opaque paint layer 19b, and the clear layer 19c painted on the back surface of the glass plate 6a are painted but may be colored films or sheets.

In addition, since the surface of the door of the refrigerator is made of one glass plate 6a, the manufacturing cost can be reduced. The clearance between the glass plate 6a and the light guiding portion 34b disposed in front of the detecting portion 14 needs to be 0.2 mm or less including the twist of the glass plate 6a. When a gap of 0.2 mm or more is generated, the input contents from the operating unit 9 may not be transmitted to the detecting unit 14 in some cases.

In addition, the substrate assembly 12 is installed in the door of the refrigerating chamber 2d provided at the uppermost portion of the refrigerator body 1, that is, the left refrigerating chamber door 2a. This height position is where the child can not reach. In addition, the position becomes easy for the user to see and easy to operate.

Further, in the case of the present embodiment, the operating section 9 and the display section 10 are not protruded from the door front plate 6 as in the prior art. Accordingly, it is difficult for a small child to recognize that the operation section 9 and the display section 10 are present. That is, it is possible to reduce prank manipulations by children.

FIG. 10 is a front view of the substrate assembly shown in FIG. 9 in a state in which a film covering the entire surface is removed. Fig. 11 is an enlarged view of a substantial part of the B-B cross section of the door shown in Fig. 1, showing in detail the light emitting means 13 for the display portion. 12 is a longitudinal sectional view of the recessed portion of the light shielding portion. 13 is a perspective view illustrating the back surface of the light guide portion 34b for the operating portion. Fig. 14 is a view for explaining the back surface of the film 16. Fig.

In the drawing, reference numeral 2a denotes a left refrigerating chamber door, 6 denotes a door front plate, 7 denotes a foam insulating material, 8 denotes a door inner plate, 11 denotes a lid, 12 denotes a substrate assembly, 16 denotes a film and 17 denotes a substrate case.

9, 10, and 11, the substrate assembly 12 includes a substrate case 17, light emitting means 13 for a display portion, a substrate 15, a film 16, light emitting means 34 for the operating portion, Shielding means 35, and the like are assembled. The light emitting means 34 for the operating unit and the light shielding means 35 are juxtaposed on the same side of the substrate 15, that is, on the front side of the substrate 15. [

On the rear side of the display unit 10, there is provided a display unit light-emitting means 13 for illuminating characters, figures, etc. of the display unit 10 from behind. The substrate 15 is formed with a plurality of holes 15b so that the light guiding portion (second light guiding means) 13b for the display portion from each of the plurality of hole portions 15b protrudes toward the front side of the substrate 15 Is installed.

A plurality of light guide portions 13b for the display portion are provided so as to correspond to characters, figures, etc. of the display portion 10 and to overlap each other in the front and rear directions. The light guide portions 13b for the display portion are formed by integrally molding a resin having translucency and the light guide portions 13b for the display portion are connected and molded on the back side of the substrate 15. [

A light shielding means made of a resin of a dark color tone (black, for example) is provided between the substrate 15 and the film 16 in order to suppress the diffusion of the light guided by the light guide portion 13b for the display portion provided on the substrate 15 35 are disposed. The light shielding means 35 is a plate-like resin material, and a plurality of hole portions 35a are formed so as to surround the light guide portions 13b for the plurality of display portions over the entire circumference. In other words, the periphery of the light guide portion 13b for the display portion located on the front side of the substrate 15 is surrounded by the plurality of frame portions forming the hole portion 35a, so that the light guide portions 13b Are independent light guide portions. By covering the entire periphery of the side surface of the light guide portion 13b for the display portion with the shielding means 35, light is less likely to leak outside the light guide portion 13b for the display portion, It is possible to uniformly display the light by suppressing illumination unevenness of characters to be displayed. In addition, it is possible to suppress leakage of light to the other light guide portion 13b for the display portion and other adjacent display characters, thereby preventing appearance designing at the time of display and erroneous display of display contents.

The light from the LED 13a for the display part can be reflected and diffused within the light-guiding part 13b for the display part by setting the light-shielding part 35 in a dark tone (for example, black) And the like can be suppressed and clearly displayed.

The light emitting means 13 for the display portion, the detecting portion 14, the light emitting means 34 for the operating portion, and the light shielding means 35 are disposed on the same surface of the substrate 15 as described above.

In the substrate assembly 12, the protruding height positions on the front side of the light shielding means 35 and the light guiding portion 13b for the display portion are the same or positioned such that the shielding means 35 is higher. Accordingly, the light from the light guide portion 13b for the display portion can be blocked by the light shielding means 35, and leakage of light to the adjacent light guide portion 13b for the adjacent display portion can be suppressed. The film 16 is provided close to or in close proximity to the light guide portion 13b for the display portion and the film 16 closes the hole portion 35a of the light shielding means 35. Therefore, It is possible to suppress leakage of light from the portion 13b.

As a result, it is possible to clearly display any one of a plurality of characters adjacent to each other, thereby improving the appearance of the display unit and the operation unit at the time of display, and erroneously operating the user by clearly confirming the setting state of the refrigerator ≪ / RTI >

In the present embodiment, the LED 13a for the display portion is a luminescent color such as blue, green, or orange, while the LED 34a for the operating portion is a luminescent color of white. The light guiding portion 13b for the display portion and the light guiding portion 34b for the operating portion are provided side by side on the front surface of the substrate 15. [ In this case, if the LED 13a for the display part and the LED 34a for the operating part emit light at the same time, mutual light may interfere with each other, which may affect the light projection or appearance of characters or figures.

Therefore, the height positions of the front surface of the light shielding means 35 and the light guiding portion 34b for the operating portion are the same or arranged such that the shielding means 35 is higher. As a result, light from each other can be blocked, and characters of the display unit 10 and the operation unit 9, which have different colors of light, can be clearly displayed.

The position of the front side of the shielding means 35 and the position of the outer peripheral edge 21a of the substrate case 17 are arranged so that they are the same or the shielding means 35 is higher toward the front side have. Thus, when the film 16 is attached to the outer edge portion (flange portion) 17a of the substrate case 17, the rear surface of the film 16 and the front surface of the light shielding means 35 are brought into close contact with or close to each other . That is, as described above, the height of the light shielding unit 35 and the light guiding unit 13b for the display unit are the same or higher than that of the light shielding unit 35. Therefore, when the film 16 is attached to the substrate case 17 , And the hole portion 35a of the light shielding means 35 is closed with the film 16.

Accordingly, light can be efficiently diffused in the light guiding portions 13b for individual display portions, thereby making it possible to clearly display the illuminance unevenness of characters to be displayed. By suppressing leakage of light from one light-guiding portion 13b to the other light-guiding portion 13b for the display portion, it is possible to prevent light projection display of unintended characters, And the display unit 10 can be clearly viewed, thereby preventing the operation unit 9 from being erroneously operated.

11, a concave portion 35b for accommodating the resistive component 13c provided on the front surface of the substrate 15 is formed on the rear surface side of the shielding means 35 and around the hole portion 35a Respectively. That is, the resistance component 13c of the LED for display unit 13a provided on the back surface of the substrate 15 is provided on the front surface of the substrate 15. [ The resistor component 13c is located near the side of the light guide portion 13b for the display portion on the front surface of the substrate 15 and is covered by the recess portion 35b provided in the shielding means 35. [ The convex portion is not formed on the front side of the shielding means 35 in order to accommodate the resistor component 13c so that the entire surface of the shielding means 35 is flat. Can be thinned.

As shown in Fig. 12, the light shielding means 35 is formed to have different angles and shapes in accordance with the outer edge 35c on the film 16 side and the outer edge 35d on the substrate 15 side. More specifically, the outer edge portion 35c located on the film 16 side is formed at a substantially right angle, and the outer edge portion 35d located on the substrate 15 side is formed in a rounded shape or an obtuse angle. By forming the outer edge of the film 16 side at a substantially right angle as described above, leakage of light from the light-guiding portion 13b for the display portion can be suppressed.

As shown in Figs. 9 and 10, a detection unit 14 for detecting a change in electrostatic capacitance is disposed on the back surface of the operation unit 9. Fig. A plurality of detecting portions 14 are provided on the surface of the substrate 15, and an LED 34a for the operating portion is provided in the vicinity thereof. A high reflective color tone (e.g., white color) is applied to a region where the detecting portion 14 of the substrate 15 and the LED 34a for the operating portion are provided. Accordingly, the light from the LED 34a for the operating portion can be reflected and the light can be uniformly diffused to the operating portion light-guiding portion 34b. Further, the white region is not particularly limited such as resist printing, silk printing, and the like.

A transparent or semitransparent light guide portion 34b for the operating portion is disposed so as to cover the front surface side of the detecting portion 14, that is, the above-described white-painted region. The light irradiated from the operating section LED 34a passes through the light guide section 34b for the operating section so that the translucent characters and figures of the film 16 are transmitted and displayed on the glass plate 6a.

As shown in Fig. 10, a plurality of LEDs 34a for the operating part are provided on the front surface of the substrate 15 and around the detecting part 14. Fig. A plurality of LED arranging portions 34c are formed in the light guiding portion 34b for the operating portion disposed on the front side of the detecting portion 14 in correspondence with the positions where the LED portions 34a for the operating portions are provided. The LED arrangement portion 34c is formed as an end concave portion or a hole-shaped portion of the light guide portion 34b for the operating portion.

The LED 34a for the operating unit and the light guiding unit 34b for the operating unit are disposed on the same side of the substrate 15 so that the light from the LED 34a for the operating unit is not irradiated toward the front side (glass plate 6a side) The light is irradiated from the LED arrangement portion 34c to be sideward as shown by the arrow R and is uniformly diffused from the side of the light-guiding portion 34b for the operating portion to the light-guiding portion 34b for the operating portion.

Since the operating portion LED 34a and the light guiding portion 34b for operating portion are juxtaposed in the width direction of the board 15 rather than in the front and rear direction of the board 15, the board assembly 12 can be made thin, It is possible to increase the thickness of the foamed heat insulator 7 to be filled on the back side of the heat sink 12, and thus the heat insulating performance can be ensured.

As shown in Fig. 13, a plurality of light-converging concave portions (first light-collecting portions) 34d made of elliptical concave grooves for concentrating the light of the operating-portion LED 34a are provided in the light-guiding portion 34b for the operating portion have. The light condensing concave portion 34d emits light so as to surround the periphery of the display character or the display graphic form of the operation unit 9 (for example, a character graphic form such as "power saving, refrigeration, refrigeration, , And a portion such as a button that the user can easily identify is displayed. The light of the LED is generally concentrated at the end portion of the light guiding member so that the light converging concave portion 34d formed at the end portion, that is, the concave groove, The annular portion surrounding the character or the displayed graphic is clearly displayed. In this embodiment, the annular portion is formed to be elliptical, but it is not limited to this shape. Since the light from the LED 34a for the operating portion is also guided into the region surrounded by the light condensing concave portion 34d, the display character or the display figure of the operation portion 9 positioned in front of the region surrounded by the light condensing concave portion 34d, .

A plurality of light-converging end recesses (second light-collecting portions) 34e, which are substantially triangular concave portions, are provided on the side of the light-guiding portion 34b adjacent to the light-shielding means 35 for the operating portion. The tip portions of the substantially triangular shapes of the light-collecting end concave portions 34e are provided so as to be close to each other between a plurality of light-converging concave portions 34d arranged adjacent to each other or arranged at a predetermined interval. Generally, the light of the LED is concentrated on the end portion of the light guiding member. In this regard, in this embodiment, a plurality of first housings (not shown) for condensing the light from the LEDs 34a for the operating part are provided at positions corresponding to the positions of the plurality of operating parts 9, (Condensing concave portion) 34d positioned between the plurality of first condensing portions 34d and the second condensing portion (condensing end concave portion) 34d located between the plurality of first condensing portions 34d in the arrangement direction of the plurality of first condensing portions 34d 34e. In other words, since the condensing end concave portion 34e is provided close to the condensing concave portion 34d, it is possible to concentrate more light on the condensing concave portion 34d.

An inclined portion (not shown) that tapers toward the light-shielding means 35 is provided on the back side of the light-guiding portion 34b for the operating portion adjacent to or close to the light-shielding means 35. [ It is possible to concentrate the light of the LED 34a for the operating portion on the condensing concave portion 34d, as in the case of the oblique light condensing end concave portion 34e.

The LEDs 34a for the operating part arranged in the longitudinal direction of the substrate 15 out of the plurality of LEDs 34a for the operating part are arranged between the adjacent detecting parts 14, And is positioned so as to be spaced apart from the edge portion of the detection portion 14 in the orthogonal direction. That is, the light from the LED 34a for operating part is irradiated in the direction of the arrow R shown in Fig. 10, and the light with the strongest directivity is irradiated between the detecting parts 14. [ This is because, when irradiated directly toward the center of the detection unit 14, there is a possibility that light is concentrated at the central portion of the character, and the roughness unevenness such as the central portion of the character to be displayed becomes excessively bright or the end portion of the character becomes dark. Therefore, by irradiating the adjacent detecting portions 14 and irradiating the two adjacent detecting portions 14 with one operating portion LED 34a, the light is evenly diffused and the display of the operating portion 9 It is possible to reduce the number of LEDs to be used while clearly displaying the illuminance unevenness of a character or a displayed figure (including the above-described annular portion).

In order to uniformly diffuse the light from the LED 34a for the operating part to the light-guiding part 34b for the operating part on at least one of the front surface or the back surface of the light-guiding part 34b for operating part, a wrinkle- Is formed on the surface of the substrate.

A substantially triangular concave-convex portion or a wave-like portion (not shown) is formed in the LED arrangement portion 34c provided in the light-guiding portion 34b for the operating portion, . Thus, the light from the LED 34a for the operating portion is uniformly diffused over the light-guiding portion 34b for the operating portion.

As shown in Fig. 14, since the back side of the film 16 is made of a white color, the light emitted from the light emitting means 34 for the operating unit and the light emitting means 13 for the display unit is diffused to suppress unevenness in display So that it can be displayed uniformly while suppressing the darkness or brightness of the part.

Further, white diffusive coating 36 is applied to the periphery of the transparent portion of the operation portion 9 and the display portion 10 on the rear surface of the film 16. This makes it possible to diffuse the light from the light-emitting means 34 for the operating portion and the light-emitting means 13 for the display portion so as to suppress unevenness in displayed characters, thereby suppressing partial darkening or brightening and displaying uniformly .

The substrate 15 is provided with a detection unit 14, a determination unit (not shown), and an automatic control unit (not shown) including a microcontroller.

The substrate 15 is covered on one side by the film 16 and the other side is covered by the substrate case 17. [ The film (16) is in close contact with the detecting portion (14). And also transmits the light from the light emitting means 13 for the display portion.

The detecting section 14 is paired with the operating section 9 on the glass plate 6a side when assembled to the left refrigerating chamber door 2a. That is, the operation section 9 is provided on the front side of the glass plate 6a and the film 16 which are insulators, and the detection section 14 is arranged on the back side (on the substrate 15 side with the film 16 therebetween) As shown in Fig.

Next, reference numeral 20 denotes a slide member. The slide members 20 are provided at four corners of the substrate case 17 as shown in Fig.

Reference numeral 21 denotes a concave portion for accommodating the substrate 15. The concave portion 21 is provided in the substrate case 17 and has a depth such that a microcontroller or the like provided in the substrate 15 can be accommodated.

The substrate case 17 is formed of a gray color tone (color by resin molding, painting, film transfer, or the like) which is a low reflection hue. When the color of the substrate case 17 is an index that easily reflects light such as white or the like, the light is reflected by the substrate case 17 on the rear surface side of the LED for the display unit 13a when the LED for the display unit 13a is made to emit light And there is a fear that leakage of light occurs. Therefore, when the color of the substrate case 17 is made to be a gray-based color that is hard to reflect light, when only a specific character among a plurality of display characters written on the display unit 10 is displayed, Is suppressed from being displayed.

The color of the substrate case 17 is not limited to gray but may be any color or surface treatment that is difficult to reflect light. It is also possible to apply a coating to a portion opposed to the light guiding portion 13b for the display portion of the substrate case 17.

Reference numeral 22 denotes a connector for connecting between the substrate 15 and another substrate (not shown) provided on the refrigerator body 1 side. The connector 22 is provided at the end of the substrate case 17 as shown in Fig.

Reference numeral 23 denotes an engagement portion provided on the bottom surface of the substrate case 17. The engaging portion 23 is provided integrally with the substrate case 17 made of resin. And is formed so as to be variable in the arrow Q direction.

Reference numeral 24 denotes an insertion portion (see FIG. 8). The insertion portion 24 is provided on the side of the door frame 2c of the left refrigerating chamber door 2a as shown in the figure. The insertion portion 24 is provided integrally with the case cover 18. In other words, the entrance portion of the space formed by the case cover 18 is constituted by the insertion portion 24.

Reference numeral 11 denotes a lid for detachably closing the insertion portion 24. As shown in Figs. 7 and 8, the lid 11 is provided so as to be flush with the door frame 2c. Accordingly, even when the user opens the left refrigerator compartment door 2a, the border between the lid 11 and the door frame 2c is not conspicuous, so that the designability is not impaired. Further, by making the lid 11 and the door frame 2c the same color, it contributes to not impairing designability.

Reference numeral 25 denotes a substrate guiding means (guide groove) provided on the case cover 18. The guide groove 25 guides the substrate assembly 12 inserted from the insertion portion 24 into the case cover 18 to guide it. That is, the slide member 20 provided on the substrate case 17 is slid in the guide groove 25 to assemble the substrate assembly 12 into the case cover 18.

At this time, the dimension between the surface side of the substrate 15 and the glass plate 6a is varied in the vicinity of the end portion 25a of the guide groove 25. That is, the guide groove 25 has a structure in which the end portion 25a guides the slide member 20 so that the detection portion 14 on the substrate 15 closely contacts or comes close to the glass plate 6a. In other words, at the time of inserting the substrate assembly 12 into the inserting portion 24, the inlet portion 25b of the guide groove 25 is formed in a position where the detection portion 14 is placed on the glass plate The end portion 25a is caused to rise so that the detection portion 14 comes close to or comes close to the glass plate 6a at the position where the assembly ends.

Further, the substrate case 17 has a rectangular shape with a long side. Then, with the slide member 20 alone as described above, the vicinity of the center of the substrate case 17 is curved, and the detecting portion 14 on the substrate 15 may be distant from the glass plate 6a.

Therefore, in the present embodiment, convex portions 17b are provided at the upper and lower ends of the rear surface center of the substrate case 17. Accordingly, when the substrate case 17 is assembled in the case cover 18, the convex portion 17b serves to correct the curvature of the substrate case. Therefore, the detection unit 14 on the substrate 15 can be provided in close contact with or close to the glass plate 6a.

8, a plurality of ribs 18a are provided on the back surface of the case cover 18. As shown in Fig. That is, a plurality of ribs 18a are provided on the side in contact with the foamed thermal insulating material 7. [

When the foaming heat insulating material 7 is filled with foam, the foaming pressure acts on the case cover 18. In this case, deformation of the case cover 18 due to the foaming pressure can be suppressed by the plurality of ribs 18a. Further, the rib 18a induces the foaming heat insulating material 7 to flow along the rib 18a, so that it functions not to hinder the filling foaming. In addition, since the foamed thermal insulating material 7 is uniformly filled and cured so as to surround the rib 18a, the case cover 18 can be securely fixed.

As a result, when the substrate assembly 12 is assembled in the case cover 18, it is possible to prevent the case cover 18 from being deformed or displaced by the filling and foaming of the foamed heat insulating material 7. Therefore, And the slide member 20 can be restrained from being displaced. That is, the detection unit 14 on the substrate 15 can be surely placed close to or close to the glass plate 6a.

Next, the case of assembling the substrate assembly 12 in the space 26 formed by the glass plate 6a and the case cover 18 will be further described with reference to Fig.

The sliding member 20 on the side of the inlet portion 25b is lightly pushed along the guide groove 25 while being positioned at the inlet portion 25b of the guide groove 25. The slide member 20 on the end 25a reaches the end 25a of the guide groove 25 so that the detection portion 14 of the substrate assembly 12 Close to or close to the glass plate 6a.

7, the slide member 20 on the side of the entrance portion 25b rides on the guide portion 25c from the entrance portion 25b and the engagement portion 23 provided on the substrate case 17 is brought into contact with the elastic force And then the stopper 27 rides on the stopper 27 after being resisted. Thus, the substrate assembly 12 is fixed in a state in which the detection unit 14 is in close contact with or close to the glass plate 6a, which is the door front plate 6, with the film 16 interposed therebetween.

Next, the connector 22 on the board side is located on the insertion side 24 side. As shown in Fig. 7, a cable wire 28 such as a power cord is previously inserted into the case cover 18. As shown in Fig. Then, the cable line side connector 29, which is the tip of the cable line 28, is inserted into the connector 22 on the board side. Thus, the cable lines 28 can be arranged in the space 26. In this state, the lid 11 is attached to complete the assembling work. Further, when removing the substrate assembly 12 at the time of inspection and repair, the opposite operation may be performed.

The cable line 28 is drawn into the space 26 from the foam insulating material 7 side of the door 2. The inlet 30 to the space 26 is provided near the lid 11 as shown in Fig. As a result, the cleaning work of the cable line 28 becomes efficient.

The inlet 30 is located above the space 26 when the left refrigerating chamber door 2a is assembled to the refrigerator body 1. [ Thus, the condensation water generated in the space 26 can be prevented from infiltrating into the foam insulating material 7 side from the inlet port 30.

Further, when the display portion 10 is formed by printing directly on the back surface of the glass plate 6a and the film 16 is removed, the following problems arise. The positional deviation of about 1 to 2 mm occurs due to the foaming pressure of the display portion 10 and the case cover 18 provided on the glass plate 6a in the step of filling the foamed thermal insulating material 7. [ That is, since the substrate assembly 12 is positioned by the guide grooves 25 provided in the case cover 18, the LEDs 13a for the display part provided on the substrate 15 and the display part 10, The positional deviation occurs between the LED 34a and the operating unit 9 respectively. Therefore, illumination unevenness occurs in the display portion 10 and the operation portion 9, which is not preferable for the appearance. In addition, it is apparently not preferable to increase the character display section in consideration of the positional deviation.

That is, by constituting the substrate assembly 12 by the substrate case 17, the substrate 15, the film 16, and the like, the case cover 18 is displaced in the process of filling the foamed thermal insulating material 7 The display portion 10 and the operating portion 9 are unlikely to be unevenly illuminated.

The substrate assembly 12 is brought into close contact with the glass plate 6a by the relationship between the four slide members 20 provided on the substrate case 17 and the guide grooves 25 provided on the case cover 18 Or close to each other. However, this is an example for bringing the detecting section 14 close to or close to the glass plate 6a, and is not limited to this configuration. Also, the position where the insertion portion 24 is provided is not limited to the door side surface described above, and may be the bottom surface, the upper surface, or the back surface (foam insulating material side) of the door.

In the assembled state, a chamfered portion 16a (an inclined portion) is formed on the end portion of the film 16 located on the insertion portion 24 side (the upper and lower ends on the right side in FIG. 9 and the upper and lower ends on the left side in FIG. Is formed. That is, the end portion of the storage chamber door (refrigerator chamber door) 2a is provided with the insertion portion 24 for integrally arranging the film 16, the substrate 15, and the substrate case 17 at predetermined positions, 16 have inclined portions (face fitting portions) 16a at upper and lower end portions located at the insertion portion 24 side at a predetermined position. Accordingly, when the substrate assembly 12 is pulled out from the insertion portion 24 at the time of inspection and repair, the end portion of the film 16 is caught by the edge of the insertion portion 24 and is prevented from being peeled off from the substrate case 17 .

In addition, by forming the chamfered portion 17a1 (inclined portion) in the end portion of the substrate case 17 located on the insertion portion 24 side in the assembled state (upper and lower right portions as viewed from the front in Figs. 9 and 10) The separation of the substrate assembly 12 can be facilitated by preventing the end portion of the substrate assembly 12 from being caught by the edge portion of the insertion portion 24 when the substrate assembly 12 is pulled out from the insertion portion 24. [ In other words, the chamfered portion 16a of the end of the film 16 and the chamfered portion 17a1 of the end of the substrate case 17 do not require the space of the insertion portion 24 to be large, Is prevented from being caught by the edge of the insertion portion (24), thereby facilitating the separation operation of the substrate assembly (12).

9, the substrate assembly 12 is composed of a substrate case 17, light emitting means 13 for a display portion, a substrate 15, a film 16, and the like. The substrate 15 is accommodated in the concave portion 21 of the substrate case 17. The front surface of the substrate 15 is accommodated so as to be flush with the flange portion 17a provided on the substrate case (substrate storing member) The adhesive film attachment film 16 is tightly fixed to the surface 15a of the substrate 15 and the flange portion 17a of the substrate case 17 in this state.

Therefore, the space portion is not present between the detection portion 14 and the film 16 on the substrate 15, or is configured to be close to the detection portion.

Next, the structure of the light emitting means 13 for the display portion will be described with reference to Fig. On the opposite side of the detection portion 14 of the substrate 15, the LED portion 13a for the display portion is disposed. A hole portion 15b is provided in the vicinity of the LED for display portion 13a. In the hole portion 15b, an LED 13a for a display portion is provided. A film 16 is disposed on the opposite surface of the hole portion 15b.

Thus, when the LED 13a for the display part is turned on, it is incident on the source 13b1 of the light-guiding part 13b for the display part disposed on the opposing face of the LED 13a for the display part. The light guiding portion 13b for the display portion is injection molded with a transparent resin of polystyrene or a transparent resin material of acrylic or the like. Therefore, as shown by an arrow in Fig. 11, the inside of the light guide portion 13b for the display portion is refracted and projected to light the surface 13b2 of the light guide portion 13b for the display portion. Thus, the display character of the film 16 is illuminated.

In addition, as shown in Fig. 9, it is necessary to display all of them corresponding to display characters such as rapid cooling, quenching, and the like printed on the film 16. Therefore, in this embodiment, as shown in Fig. 9, a plurality of holes 15b and LEDs 13a for a display portion are provided on the substrate 15, and light guide portions for display portions (corresponding to the plurality of holes) 13b.

According to this configuration, the thickness of the substrate case 17 in which the substrate 15 is embedded can be suppressed, and the thickness of the foamed heat insulating material 7 can be sufficiently secured.

Although not shown, when the lighting is instructed from the automatic control unit, the display unit 10 is illuminated from the back side of the film 16 so that the glass plate 6a is transmitted through the glass plate 6a to light up the characters.

In other words, the display unit light-emitting unit 13 in this embodiment is lit only when the detecting unit 14 detects the electrostatic capacitance. Then, in the actual use state, it is difficult for a small child to recognize that the glass plate 6a itself is the operation unit 9. [ Therefore, playfulness and the like can be prevented.

The characters displayed on the film 16 by printing or the like can be viewed by the user through the glass plate 6a.

The lighting of the light-emitting means 13 for the display unit is performed as follows. That is, when the user touches the operation portion 9 of the character portion shown on the front surface through the glass plate 6a, the detection portion 14 detects this when the user touches the finger or the like. Then, the judging unit and the automatic control unit are operated, for example, when the rapid cooling is instructed, the display unit 10 lights up so as to illuminate the character part of "rapid cooling".
