Description

  The present invention relates to a refrigerator.

  As a conventional refrigerator, a configuration is known in which an operation part (for example, a push button) is provided on the front part of the door, and by operating the operation part, various functions such as quick freezing, quick refrigeration, and automatic ice making device are operated. Yes. As the operation unit, a mechanical switch such as a micro switch is known.

  Furthermore, some recent home appliances use a capacitive touch switch. An example of a refrigerator provided with a touch switch is described in Patent Document 1.

  In the configuration described in Patent Document 1, a touch switch having a touch electrode and a counter electrode portion is provided on the front surface of the door. Further, the front surface portion of the touch electrode protrudes to the front side of the operation panel. The counter electrode part includes a double-sided printed board corresponding to an insulator and a pair of electrodes. In this configuration, when the user's hand or finger touches the touch electrode, the capacitance between the electrodes changes. This change in capacitance is taken out as a switch on / off signal.

  Further, Patent Document 2 is cited as a refrigerator in which an outer plate on the door surface is made of transparent plastic or glass, an operation unit is printed on the surface of the outer plate, and a display unit is provided on the back of the operation unit. In this device, when the printed operation unit is pressed by hand, a magnetic field or body temperature generated by the hand is detected and the driving state is displayed on the display unit.

  However, in the configuration described in Patent Document 1, since the touch electrode protrudes to the front side of the operation panel, when the user operates the touch switch with a wet hand or finger, moisture is a gap between the portions where the touch switch is provided. There is a risk of damaging the electrical components.

  Further, when the surface of the door is to be wiped and cleaned, since it is not a flat surface, cleaning around the touch switch is complicated, and forcibly wiping and cleaning may cause malfunction or failure of the switch.

  Moreover, when a user operates a touch electrode with the hand and finger | toe to which oil and fat adhered, there exists a possibility that a touch electrode may corrode and may deteriorate early.

  Next, since the refrigerator described in Patent Document 2 includes an operation unit printed on the surface of a transparent outer plate such as plastic or glass and operates the operation unit, the refrigerator is provided between the touch switch and the glass. There is no gap for water to enter, and even if the touch switch is operated with wet hands or fingers or cleaned with a wet cloth, water will not enter the touch switch. This is a case where the operation unit and the display unit are arranged at the center of the door as in the embodiment of Patent Document 2, and the operation unit is connected to the door as shown in FIGS. 1 and 2 of the conventional example of Patent Document 2. When the display unit is placed on the back of the glass facing this operation unit, even if the display unit is placed on the back side of the glass, water will flow through the gap between the door frame at the bottom of the door and the glass. There is a risk that water will reach the display part near the back surface of the glass due to infiltration and capillarity, or cause water to break down, or the operation of the operation part may not be accurately sensed, resulting in erroneous display or malfunction.

  The above-mentioned patent documents show that when water enters the inside of a glass plate, the hue of the paint that has colored the glass with water seems to change partially, and in the long term, the paint and other surrounding materials are altered. No consideration is given to the possibility of discoloration.

  In view of the above problems, an object of the present invention is to provide a refrigerator including an operation unit with improved operability and cleanability.

Yes.

  As shown in FIG. 4, the foam heat insulating material 7 is filled and foamed between the door front plate 6 made of the glass plate 6 a and the door inner plate 8. The plate thickness of the glass plate 6a which is the door front plate 6 is 2 mm to 3.5 mm in this embodiment. This plate thickness is a dimension in which the glass plate 6a is not broken or cracked by an impact generated when the refrigerator is assembled, when the refrigerator is transferred, and when the refrigerator is used.

  Further, when further securing the strength or reducing the plate thickness, the glass plate 6a may be subjected to a heat strengthening process, a chemical strengthening process, or the like. The glass plate 6a is an insulator.

  Next, in FIG.1 and FIG.2, 9 is an operation part. The operation unit 9 is operated by the user from the outside to set the room temperature of each storage room such as the refrigerating room 2d and the freezing room 4d1, rapidly cooling the refrigerating room 2d and the freezing room 4d1, Set the size. Also, it is provided in the refrigerator compartment 2d, and the storage space is depressurized or hypoxic to adjust the temperature of the storage chamber (not shown) for maintaining the freshness of stored foods and suppressing oxidative degradation, or reducing the pressure or reducing oxygen. Or set to turn off the function. That is, when the user operates the operation unit 9, various functions of the refrigerator can be set.

  Reference numeral 10 denotes a display unit. The display unit 10 displays the input result from the operation unit 9 on the outside of the refrigerator body 1. Thereby, it is possible to confirm the operation performed by the user on the operation unit 9 or to confirm the states of various functions set in advance.

  The operation unit 9 and the display unit 10 are not provided with a special panel, but are provided on the glass plate 6a. That is, the glass plate 6a provided in the left refrigerator compartment door 2a is provided so that it may become a plane over the whole outer surface of this left refrigerator compartment door 2a including the operation part 9 and the display part 10. FIG.

  In other words, the operation unit 9 and the display unit 10 are directly provided on the door front plate 6 which is the glass plate 6a. For this reason, the conventional operation panel is omitted.

  Further, a colored paint is applied to the back surface of the glass plate 6a except for the display unit 10. Thereby, the foam heat insulating material 7 is processed so as not to be seen from the front side, and the display unit 10 is clearly visually recognized, so that a door having excellent appearance is configured.

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

  In FIG. 2, the display of the character part (characters of freezing, refrigeration, ice making, rapid cooling, and vacuum chilling) surrounded by a broken line is represented by direct printing or the like on the back surface of the glass plate 6a. On the other hand, the operation unit 9 refers to the front surface (front surface of the glass plate 6a which is the door front plate 6) at a position facing the back surface on which the character portion is printed. In addition, as a means for providing an operation display (the character portion) on the back surface of the glass plate 6a, etching, inlaying, and the like can be given in addition to printing.

  Further, in FIG. 2, a part surrounded by a solid line is a display unit 10 that indicates a setting state of various functions in accordance with an input by the operation of the operation unit 9 described above. And this character display ("strong (low temperature), medium, weak", "strong (chilled), medium, weak", "large, standard, stop", "quick refrigeration, quick freezing", "vacuum ice temperature, vacuum "Chilled, cut (ice temperature)") is expressed by printing or the like on the film surface described later.

  The said film is attached to the back surface of the glass plate 6a which is the door front plate 6 so that the adhesion or the gap is very slight. Therefore, the character display can be clearly confirmed from the front of the left refrigerator compartment door 2a through the glass plate 6a. In other words, the door has an excellent appearance and has a high visibility and an outer surface made of a flat glass plate.

  The operation unit 9 and the display unit 10 are provided side by side as shown in FIG. The display unit 10 is configured to display, as a function of the refrigerator body 1, that quick refrigeration or quick freezing is in operation.

  Furthermore, 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 to project to the front surface of the glass plate 6a so as to be lifted up.

  Next, in FIG. 3, 11 is a lid provided on the side surface of the left refrigerator compartment door 2a. The lid 11 is provided on the opposite hinge side of the left refrigerator compartment door 2a, and is provided between the adjacent right refrigerator compartment door 2b. In this configuration, when the left refrigerator compartment door 2a and the right refrigerator compartment door 2b are closed, the lid 11 is not visible from the user.

  Next, in FIG. 4, 2a is a left refrigerator compartment door, 6 is a door front board, 7 is a foam heat insulating material, 8 is a door inner board, 12 is a board | substrate assembly. The board assembly 12 includes an LED light emitting unit 13 that illuminates the display unit 10, a detection unit 14 that detects a change in capacitance, a determination unit (not shown), an automatic control unit (not shown) including a microcomputer, and the like. A substrate 15, a film 16 on which display characters are printed, a substrate case 17, and the like.

  The substrate 15 (including the detection unit 14) has one surface on the front side of the substrate 15 covered with a film 16 and the other surface covered with a substrate case 17. The film 16 is in close contact with the detection unit 14. Moreover, the film 16 is the structure which permeate | transmits the light of the LED light emission part 13 from the back surface to the surface, and permeate | transmits it to the glass plate 6a side.

  The detection unit 14 is paired with the operation unit 9 when assembled in the left refrigerator door 2a. That is, as shown in FIG. 4, the operation unit 9 is provided on the front side and the detection unit 14 is provided on the back side through the glass plate 6a and the film 16 which are insulators.

  A determination unit (not shown) detects a change in capacitance between the operation unit 9 and the detection unit 14 in the substrate 15. When there is a change in the capacitance, an oscillation circuit that oscillates and changes in amplitude according to the change in the capacitance is included. As a result, the automatic control unit that has extracted the switch signal and the on / off signal output from the determination unit drives the load. Depending on the operation of the user simply passing in front of the operation unit 9 or the user wiping the front of the refrigerator (the left refrigeration room door 2a) for cleaning, the switch signal output by the determination unit, The off signal is not output.

  That is, the glass plate 6a constituting the door front plate 6 of the refrigerator is an insulator and a light-transmitting plate material. And the operation content of the operation part 9 is displayed by the character represented by printing etc. on the back surface of the operation part 9 of the glass plate 6a so that the front surface of the glass plate 6a may be the operation part 9.

  On the back surface of the glass plate 6 a facing the operation unit 9, a detection unit 14 provided on the substrate 15 and connected to the determination unit is provided so as to be close to each other through the film 16. Character display on the display unit 10 or the like provided along with the operation unit 9 is represented by printing or the like on the surface of the film 16 covering the surface of the substrate 15.

  And the character display of the display part 10 is clearly illuminated by the LED light emission part 13 provided on the board | substrate 15 from the back surface. Further, when a hand or a finger touches the operation unit 9, the detection unit 14 on the substrate 15 senses a change in capacitance with the glass plate 6 a and notifies the determination unit on the substrate 15. And if a determination part detects an input, a load will be operated via an automatic control part.

  Here, in the case of rapid cooling, the load operated via the automatic control unit is a forced continuous operation of a refrigeration cycle, a forced continuous operation of a cold air circulation fan (not shown), or a forced forced operation of a damper that controls a cold air supply amount. Such as “open” control. By controlling these loads, the refrigerator compartment 2d is rapidly refrigerated or the freezer compartment 4d1 is rapidly frozen.

  When the detection unit 14 for detecting the change in capacitance is provided on the substrate 15 and the determination unit determines the change in capacitance, the buzzer provided on the substrate 15 emits a notification sound and changes in the control contents. As a result, the notification sound is scaled.

  The above will be specifically described with reference to FIG. When adjusting the temperature of the refrigerator compartment 2d or the freezer compartment 4d1 to the setting of “strong, medium, weak”, in this embodiment, the notification sound is scaled in the following cycle.

  “Weak (bass“ Do ”) → Medium (Medium tone“ Mi ”) → Strong (High tone“ So ”) → Weak (Low tone“ Do ”) →…” Even so, the temperature setting can be confirmed by the difference in the scales.

  Moreover, the selection additional function such as quick freezing and quick refrigeration changes the scale and the number of notifications to the notification sound in the following cycle when input.

  “Rapid freezing (bass“ Do ”) → Rapid refrigeration (medium“ Mi ”) → Quick refrigeration and rapid refrigeration (high sound“ So ”) → Stop (2 high sounds“ La, La ”) → Quick freeze (Low sound“ Do ”) ") ..."

  In particular, when no additional function (stop) is selected, the user can easily confirm the settings by hearing, even if they do not recognize it visually, by setting the number of notification sounds to multiple times as described above. Can do.

  Next, in FIG. 4, 18 is a case cover. The case cover 18 serves to isolate the substrate assembly 12 from the foam insulation 7. In addition, the substrate assembly 12 is held in the case cover 18 so that the film 16 on the surface of the substrate 15 is in close contact with or close to the glass plate 6a which is the door front plate 6.

  Reference numeral 19 denotes a colored paint surface applied to the back surface of the glass plate 6a. The colored paint surface 19 is provided over the entire back surface of the glass plate 6 a except for the display unit 10.

  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 and the glass is broken or cracked. Moreover, this protective film 19a is affixed on the same surface as the colored paint surface. This prevents the foam heat insulating material 7 from seeing through from the front side of the door, thereby preventing the appearance from being impaired.

  Moreover, the short direction of the board | substrate assembly 12 and the short direction of the glass plate 6a are arrange | positioned so that it may cross | intersect. This is based on the property that when heat treatment is applied to the glass plate 6a, the distortion of the glass plate 6a tends to appear in the longitudinal direction. That is, in view of this property, the configuration is configured to suppress the influence of the distortion of the glass plate 6a when the base assembly 12 is installed.

  Here, when the substrate assembly 12 is incorporated so that the longitudinal direction of the glass plate 6 a is along the longitudinal direction of the glass plate 6 a, the glass plate 6 a is affected by the distortion, and between the glass plate 6 a and the detection unit 14 on the substrate 15. It becomes easy to produce a gap in. Thereby, the subject that the input content from the operation part 9 is not transmitted well to the detection part 14 arises.

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

  Moreover, manufacturing cost can be reduced by making the door surface of a refrigerator into the glass plate 6a of 1 sheet. The gap between the glass plate 6a and the detection unit 14 needs to be 0.2 mm or less including the distortion of the glass plate 6a. It has been found by a test etc. of the present inventors that when the gap of 0.2 mm or more occurs, there arises a problem that the input content from the operation unit 9 is not transmitted well to the detection unit 14.

  Moreover, the board | substrate assembly 12 is provided in the door of the refrigerator compartment 2d provided in the uppermost part of the refrigerator main body 1, ie, the left refrigerator compartment door 2a. This height position is a position out of reach of small children. In addition, the position is easy to see and operate for the user.

  Furthermore, in the case of this embodiment, the operation part 9 and the display part 10 do not protrude from the door front plate 6 as in the prior art. Thereby, it is difficult for a small child to recognize that the operation unit 9 and the display unit 10 are present. That is, mischievous operations by children can be reduced.

[Embodiment 2]
Next, a second embodiment of the present invention will be described with reference to FIGS.

  FIG. 5 is a top view of the substrate assembly according to the embodiment of the present invention. FIG. 6 is a cross-sectional view of the door shown in FIG. FIG. 7 is a diagram for explaining the substrate case according to the embodiment of the present invention. FIG. 8A is an exploded perspective view of the board assembly according to the embodiment of the present invention. FIG. 8B is a cross-sectional view of the door shown in FIG.

  In the figure, 2a is a left refrigerator door, 6 is a door front plate, 7 is a foam insulation, 8 is a door inner plate, 11 is a lid, 12 is a substrate assembly, 16 is a film, and 17 is a substrate case.

  As shown in FIGS. 8A and 8B, the substrate assembly 12 is a combination of a substrate case 17, an LED light emitting unit 13, a substrate 15, and a film 16 in that order.

  On the back surface of the display unit 10, an LED light emitting unit 13 that illuminates the display unit 10 later is located. That is, the substrate 15 positioned on the back surface of the display unit 10 has a shape in which a part thereof is cut out, and is provided so that the LED light emitting unit 13 faces the cutout part.

  On the back surface of the operation unit 9, a detection unit 14 that detects a change in capacitance is located. The substrate 15 includes a detection unit 14, a determination unit (not shown), an automatic control unit (not shown) including a microcomputer, and the like.

  One side of the substrate 15 is covered with a film 16 and the other side is covered with a substrate case 17. The film 16 is in close contact with the detection unit 14. Further, the light from the LED light emitting unit 13 is transmitted.

  The detection unit 14 is paired with the operation unit 9 on the glass plate 6a side when being assembled into the left refrigerator door 2a. That is, the operation unit 9 is provided on the front side of the glass plate 6a and the film 16 which are insulators, and the detection unit 14 is provided so as to overlap as shown in FIG. 4 so as to be on the back side (substrate 15 side through the film 16). Yes.

  Next, 20 is a slide member. As shown in FIG. 8A, the slide members 20 are provided at the four corners of the substrate case 17, respectively.

  Reference numeral 21 denotes a recess for accommodating the substrate 15. The recess 21 is provided in the substrate case 17 and has a depth in which a microcomputer or the like included in the substrate 15 is accommodated.

  22 is a connector for connecting between the board | substrate 15 and another board | substrate (not shown) provided in the refrigerator main body 1 side. The connector 22 is provided at the end of the substrate case 17 as shown in FIG.

  Reference numeral 23 denotes a locking portion provided on the bottom surface of the substrate case 17. The locking portion 23 is provided integrally with the resin substrate case 17. It has elasticity and is formed to be variable in the direction of arrow Q.

  Reference numeral 24 denotes an insertion portion (see FIG. 7). The insertion portion 24 is provided on the side surface of the door frame 2c of the left refrigerator compartment 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 configured by the insertion portion 24.

  11 is a lid for detachably closing the insertion portion 24. As shown in FIGS. 6 and 7, the lid 11 is provided so as to form a plane with the door frame 2 c. Thereby, even if a user opens the left refrigerator compartment door 2a, the boundary of the lid | cover 11 and the door frame 2c is not conspicuous, and designability is not impaired. Moreover, it contributes not to impair design property by making the lid | cover 11 and the door frame 2c into the same color.

  Reference numeral 25 denotes a guide groove provided in the case cover 18. The guide groove 25 guides the substrate assembly 12 inserted from the insertion portion 24 by sliding it into the case cover 18. That is, the slide member 20 provided in the substrate case 17 is slid in the guide groove 25 to incorporate the substrate assembly 12 in 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 terminal 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 is in close contact with or close to the glass plate 6a. In other words, when the board assembly 12 is inserted into the insertion portion 24, the inlet portion 25b of the guide groove 25 slides the detection unit 14 at a position away from the glass plate 6a in consideration of the ease of assembly of the board assembly 12. Thus, the end portion 25a is configured to rise so that the detection portion 14 is in close contact with or close to the glass plate 6a at the position where the assembly is completed.

  The substrate case 17 has a horizontally long rectangular shape. Then, only the slide member 20 as described above may cause the vicinity of the center of the substrate case 17 to bend, and the detection unit 14 on the substrate 15 may be separated from the glass plate 6a.

  Therefore, in the present embodiment, convex portions 17 b are provided on the upper and lower ends from the center of the back surface of the substrate case 17. Thereby, when the substrate case 17 is incorporated in the case cover 18, the convex portion 17b acts to correct the curvature of the substrate case. Therefore, the detection part 14 on the board | substrate 15 can be provided so that it may contact | adhere or adjoin to the glass plate 6a.

  Further, as shown in FIG. 7, a plurality of ribs 18 a are provided on the back surface of the case cover 18. That is, a plurality of ribs 18 a are provided on the side in contact with the foam heat insulating material 7.

  When the foam heat insulating material 7 is filled and foamed, the foaming pressure acts on the case cover 18. In this case, deformation of the case cover 18 due to foaming pressure can be suppressed by the plurality of ribs 18a. Further, the rib 18a guides the foam heat insulating material 7 to flow along the rib 18a, and thus acts so as not to inhibit the filling foam. Furthermore, since the foam heat insulating material 7 is uniformly filled so as to surround the rib 18a and hardened, the case cover 18 can be securely fixed.

  As described above, since the case cover 18 can be prevented from being deformed or displaced by filling and foaming of the foam heat insulating material 7, when the substrate assembly 12 is assembled in the case cover 18, the guide groove 25 and the slide member The positional deviation with respect to 20 can be suppressed. That is, the detection unit 14 on the substrate 15 can be provided so as to be in close contact with or close to the glass plate 6a.

  Next, the case where the board assembly 12 is assembled in the space 26 formed by the glass plate 6a and the case cover 18 will be described with reference to FIG.

  The slide member 20 on the inlet portion 25b side is lightly pushed along the guide groove 25 while being positioned at the inlet portion 25b of the guide groove 25. Then, the slide member 20 on the end portion 25a side reaches the end portion 25a of the guide groove 25, and the detection portion 14 (see FIG. 4) of the substrate assembly 12 is in close contact with or close to the glass plate 6a via the film 16. .

  As shown in FIG. 6, the slide member 20 on the inlet portion 25 b side rides on the guide portion 25 c from the inlet portion 25 b, and the locking portion 23 provided on the board case 17 gets over the stopper 27 against the elastic force. Then, it is locked to the stopper 27. Thereby, the board | substrate assembly 12 is fixed in the state which the detection part 14 contact | adhered or adjoined to the glass plate 6a which is the door front plate 6 via the film 16. FIG.

  Next, the board-side connector 22 is located on the insertion portion 24 side. As shown in FIG. 7, a cable line 28 such as a power cord is drawn out into the case cover 18 in advance. 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. Thereby, the cable wires 28 can be collected in the space 26. In this state, the lid 11 is attached and the assembling work is completed. In addition, when removing the board | substrate assembly 12 at the time of inspection and repair, what is necessary is just to perform operation reverse to the above.

  The cable wire 28 is drawn out to the space 26 from the foamed heat insulating material 7 side of the door 2. As shown in FIG. 6, the outlet 30 to the space 26 is provided near the lid 11. Thereby, the work of grouping the cable wires 28 becomes efficient.

  Further, the drawer opening 30 is positioned above the space 26 when the left refrigerator compartment door 2a is incorporated in the refrigerator main body 1. Thereby, the dew condensation water attached to the space 26 can be prevented from entering the foam heat insulating material 7 from the outlet 30.

  In addition, when it is set as the structure which forms the display part 10 by printing etc. directly on the back surface of the glass plate 6a, and removes the film 16, the following subject arises. In the process of filling the foam heat insulating material 7, the display unit 10 and the case cover 18 provided on the glass plate 6a are displaced by about 1 mm or so due to the foaming pressure. That is, since the substrate assembly 12 is positioned by the guide groove 25 provided in the case cover 18, a positional deviation occurs between the LED light emitting unit 13 provided on the substrate 15 and the display unit 10. For this reason, uneven illumination occurs in the display unit 10, which is not preferable in appearance. In addition, it is not preferable in view of appearance to enlarge the character display portion in consideration of the positional deviation.

  That is, the substrate assembly 12 includes the substrate case 17, the substrate 15, the film 16, and the like, so that the illumination of the display unit 10 can be performed even when the case cover 18 is displaced in the process of filling the foamed heat insulating material 7. This configuration is less likely to cause unevenness.

  In the present embodiment, the structure in which the substrate assembly 12 is brought into close contact with the glass plate 6a in relation to the four pieces of slide members 20 provided in the substrate case 17 and the guide grooves 25 provided in the case cover 18 has been described. However, this is an example for making the detection part 14 contact | adhere to the glass plate 6a, and is not limited to this structure. Further, the position where the insertion portion 24 is provided is not limited to the door side surface described above, and may be the door bottom surface, top surface, or back surface (foaming heat insulating material side).

  Next, in FIG. 8A, the board assembly 12 includes a board case 17, an LED light emitting unit 13, a board 15, a film 16, and the like. Then, the substrate 15 is accommodated in the recess 21 of the substrate case 17. The surface 15 a of the substrate 15 is stored so as to be flush with the flange portion 17 a provided on the substrate case (substrate storage member) 17. In this state, the adhesive-attached film 16 is tightly fixed to the surface 15 a of the substrate 15 and the flange portion 17 a of the substrate case 17.

  Accordingly, there is no space portion between the detection portion 14 on the substrate 15 and the film 16 or the proximity thereof.

  Next, the configuration of the LED light emitting unit 13 will be described with reference to FIG. 8B. The LED 13b is disposed on the opposite surface of the detection unit 14 of the substrate 15. A hole 15b is provided in the vicinity of the LED 13b. An LED translucent portion 13a is installed in the hole portion 15b. The film 16 is disposed on the opposing surface of the hole 15b.

  Thereby, when the LED 13b is turned on, the light is incident on the root 13c of the LED translucent portion 13a disposed on the opposite surface of the LED 13b. The LED translucent part 13a is injection-molded with a polystyrene transparent resin or an acrylic transparent resin material. Therefore, as indicated by the arrow in FIG. 8B, the LED translucent portion 13a is refracted and translucent to light the surface 13d of the LED translucent portion 13a. Thereby, the display character of the film 16 is illuminated.

  As shown in FIG. 8A, it is necessary to illuminate all the characters corresponding to display characters such as quick refrigeration and quick freezing printed on the film 16. Therefore, in this embodiment, as shown in FIG. 8A, a plurality of hole portions 15b and LEDs 13b are provided in the substrate 15, and a plurality of LED light transmitting portions 13a are provided so as to correspond to the plurality of hole portions.

  According to this configuration, the thickness of the substrate case 17 containing the substrate 15 can be minimized, and the thickness of the foam heat insulating material 7 can be sufficiently ensured.

  Although not shown, when a lighting instruction is given from the automatic control unit, the display unit 10 is illuminated from the back side of the film 16 and is lit up through the glass plate 6a to make the characters easier to see.

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

  In addition, the character represented by printing etc. on the film 16 can be visually recognized by the user through the glass plate 6a.

  The LED light emitting unit 13 is turned on as follows. That is, when the user touches the operation portion 9 of the character portion that is visible on the front surface through the glass plate 6a, the detection unit 14 detects this. Then, a determination part and an automatic control part operate | move, for example, when quick refrigeration is instruct | indicated, it will light to illuminate the character part of "rapid refrigeration" of the display part 10. FIG.

  Since the present invention has the configuration of each embodiment described above, the following effects can be obtained.

  That is, the door front plate of the refrigerator is a glass member having insulation and translucency. Then, the front surface of the glass member is used as a planar operation portion, and a character display portion printed on the back surface of the glass member is provided behind the operation portion. Further, on the back surface of the glass member facing the operation unit, a detection unit connected to the determination unit on the substrate is provided in contact with or close to the operation unit, and a character display such as a display unit for displaying the operation result is provided in the vicinity of the operation unit. . Moreover, the character display of this display part is irradiated from back by the light emitting diode etc. which were provided in the board | substrate.

  When the detection unit detects a change in capacitance, the automatic control unit operates the load via the determination unit on the substrate to control the on / off of the LED.

  Thereby, since the door front plate becomes an insulator and is made of a translucent glass plate, the operation unit that hits the touch electrode becomes the glass front, and an operation panel is unnecessary. Further, when the front surface of the glass is soiled with moisture, oil or the like, the front surface of the glass is flat and can be easily wiped off. Moreover, the mischief of a child can be suppressed. Moreover, even if the user touches the operation unit with a hand or finger with moisture or oil and fat on it, the operation unit is a glass member itself, so that corrosion and deterioration of the electrical product can be suppressed. Moreover, since the door surface is a flat surface, wiping and cleaning are easy.

  Further, the display unit provided along with the operation unit is illuminated from behind by an LED or the like according to an instruction from the automatic control unit on the substrate, and is displayed on the surface of the glass member.

  As a result, the user can confirm the contents input by the user by displaying the door surface without opening and closing the door, thereby preventing erroneous input and unnecessary opening and closing of the door.

  The substrate also includes an LED light emitting unit that illuminates the display unit, a detection unit that detects a change in capacitance, a determination unit, an automatic control unit including a microcomputer, and the like. The substrate is covered with a film and a substrate case, and is provided so that the film is in contact with or close to the detection unit, and the detection unit is in contact with or close to the glass plate via the film.

  As a result, the positional relationship between the operation unit and the determination unit is kept constant, and the microcomputer and the like are protected by the film and the substrate case to reduce the possibility of damage. Further, when the substrate case is attached, there is no possibility that the back surface of the glass member is damaged by the substrate case.

  In addition, the substrate case containing the substrate is housed in a case cover isolated from the foam insulation, and the film in contact with or close to the detector provided on the surface of the substrate is in contact with or close to the back surface of the glass member. It is attached to do.

  Thereby, it can prevent that the board | substrate incorporated in the board | substrate case fails by the penetration | invasion of the foaming heat insulating material with which it fills.

  In addition, a colored paint is provided on the rear surface of the glass member other than the display unit.

  Thereby, the transparency of a display part is maintained and the glass protective material, the foam heat insulating material, etc. which were affixed on the glass back surface cannot be seen from the door front, and shall be favorable on an external appearance.

  The board also includes an LED that illuminates the display unit, a detection unit that detects a change in capacitance, an automatic control unit including a determination unit and a microcomputer, and the detection unit is arranged on the substrate surface on the door surface side. Then, an LED for illuminating the display unit is arranged on the opposite surface of the substrate on which the detection unit is arranged. Moreover, a square hole is provided around the board | substrate which has arrange | positioned LED, and a display part is provided in the opposing surface of the said square hole.

  Thereby, the thickness of the board | substrate case which incorporated the board | substrate can be reduced, and the thickness of a foam heat insulating material can fully be ensured.

  Further, the glass member has a planar shape that is long in the height direction, the substrate is in a horizontally long shape, and the longitudinal direction of the substrate is disposed so as to intersect the height direction of the glass member. The thickness of the glass member is 2 mm to 3.5 mm.

  Thereby, it is possible to prevent the glass plate from being cracked or cracked when filling with the foam insulation, when using the refrigerator, or when assembling the refrigerator. Moreover, the influence of the thermal deformation etc. of glass itself can be suppressed to the minimum. In addition, the manufacturing cost can be reduced.

  The reason why the thickness of the glass member is changed from 2 mm to 3.5 mm is as follows. That is, the impact received by the glass member that is the door front plate is taken into account when the foam insulation material is filled, the refrigerator is used, the refrigerator is assembled, and the refrigerator is transported. Specifically, when a 1 kg copper ball is dropped from a height of 1 m above the door, the strength is ensured that the glass member does not break.

  Moreover, in order to ensure the further intensity | strength, you may add a heat strengthening process or a chemical strengthening process to a glass member. Moreover, in order to reduce the mass of the refrigerator itself, it is preferable that the thickness of the glass member is thinner as long as the strength can be secured.

  In the case of the present embodiment, as described above, a protective material is pasted on the back surface of the glass member so that fragments are not scattered even if the glass member is broken. Furthermore, when a tempering process is added, the broken glass becomes smaller and safety can be improved.

  Moreover, the thickness dimension of a glass member, a film, and a protective film is thickness which can detect the change of the electrostatic capacitance by operation of an operation part in a detection part.

  In addition, a detection unit that detects a change in capacitance is provided on the substrate, and when the determination unit determines the change in capacitance, a buzzer that is notification means provided on the substrate emits a notification sound. Note that the notification sound is provided with a scale or the number of notification sounds is changed in accordance with the change in the control content.

  Thereby, when a user performs operation, the content inputted by sound can be confirmed by the scale of the notification sound and the number of notification sounds. Since the door surface plate of the refrigerator is made of a glass member without unevenness and is provided with a planar operation portion, it is important that the contents can be confirmed with sound.

  In addition, when the board assembly is assembled into the case cover from the insertion part provided on the door, the surface of the board assembly is related to the guide groove and terminal part provided on the case cover and the slide member provided on the board cover. Contact or approach the back of the glass plate.

  As a result, the substrate assembly can be accommodated without damaging the determination unit and the rear surface of the glass plate. Also, the substrate assembly can be attached and detached with a small force.

  Further, the substrate is detachably mounted in the case cover from the insertion portion provided on the side surface, top surface, or bottom surface of the door, and the insertion portion is closed with a lid.

  Thereby, it is hard for a user to visually recognize an insertion part, and it can be set as the design excellent in design. Further, the service of the board assembly can be checked by opening and closing the lid without separating the door from the refrigerator body.

  In addition, the board is removably attached to the case cover from the door edge, that is, the insertion portion provided on the side, top, or bottom, and the cable wire connector is drawn into the case cover after the board is attached. To the board side connector.

  Thereby, connection / storage work of a cable line becomes easy.

  Further, the locking portion formed integrally with the resin substrate case has elasticity, and the locking portion is locked to a stopper on the case cover side using the elasticity, and the substrate case is placed inside the case cover. Secure to.

  Accordingly, when an impact is applied to the refrigerator main body, the position of the board assembly mounted in the case cover is prevented from shifting, and the detection unit is prevented from being unable to detect a change in capacitance.

[Embodiment 3]
Next, Embodiment 3 will be described with reference to FIGS. In addition, about the same component as Embodiment 1 and 2, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted. Moreover, although it demonstrates using the left refrigerator compartment door, the other door is also the structure substantially the same except the presence or absence of an operation part and a display part.

  The refrigerator door in the present embodiment also includes a glass plate 6a that is a door front plate having translucency on its outer surface. The glass plate 6 a is stored in a storage unit provided in the door frame 3. The storage portion is composed of a front flange 2c1 and an inner flange 2c2. In the illustrated embodiment, the lower end portion is supported by being sandwiched between the inner flange 2c2 and the front flange 2c1.

  A colored paint surface 19 is provided on the back surface of the glass plate 6a. A waterproof protective film 19a, which is a paint protection member, is attached to the surface of the colored paint surface 19. Thus, even if water enters from the gap between the glass plate 6 a and the front flange 2 c 1, the intruded water is protected from penetrating the colored paint surface 19.

As the protective film 19a, a vinyl chloride sheet was used. This is the adhesive strength between the foamed insulating material 7, an iron plate is about 8N / mm ^2, ABS is about 4~6N / mm ^2, a vinyl chloride sheet is a 2.4~3.3N / mm ² degree Low. Thereby, it is easy to separate the glass plate 6a from the foam heat insulating material. In other words, the protective film 19a is weak in adhesiveness with the foam heat insulating material 7, and the glass plate 6a can be easily separated and removed from the door when the refrigerator is disassembled. Use a low one. Specifically, when the refrigerator to be disassembled is disassembled at a recycling center or the like, it is easy to separate and remove only the glass plate 6a as a recycled material.

  Further, a holding member 31 is interposed between the protective film 19a and the foamed heat insulating material 7, and the two members are held so that the protective film 19a and the foamed heat insulating material 7 are not bonded. Thereby, the high temperature heat at the time of foaming the foam heat insulating material 7 and various influences due to the viscosity, the foaming pressure, the time passage, etc. when the high temperature foam heat insulating material flows are prevented from being transmitted to the protective film 19a. Can be held.

  Further, a vacuum heat insulating material 32 is attached to the holding member 31 between the protective film 19a and the foamed heat insulating material 7 by an adhesive means such as an adhesive tape or hot melt (not shown). Thereafter, the foam insulation 7 is positioned and fixed at a predetermined position. That is, the holding member 31 is interposed so that the vacuum heat insulating material 32 and the glass plate 6a are close to each other.

  The vacuum heat insulating material 32 attached to the holding member 31 is disposed so that the holding member 31 is interposed between the surface of the protective film 19a (the protective film 19a and the holding member 31 are not bonded and fixed). This is because, if the vacuum heat insulating material 32 is directly attached to the surface of the protective film 19a with an adhesive tape, it is difficult to remove the vacuum heat insulating material 32 and the efficiency of the dismantling work at the time of recycling deteriorates.

  By interposing the holding member 31, the vacuum heat insulating material 32 and the protective film 19 a are prevented from adhering, and the glass plate 6 a provided with the colored paint surface 19 and the protective film 19 a and the vacuum heat insulating material 32 are easily separated. doing.

The lower end portion of the holding member 31 is housed and supported between the inner flange 2c2 and the front flange 2c1 together with the glass plate 6a using the enlarged portion 2c4 whose gap increases toward the upper end of the inner flange 2c2. At this time, the holding member 31 is disposed so as not to contact the bottom surface portion 2c3 of the door frame 2c. Thus, and with the holding member 31 and the door frame 2c of the bottom portion 2c3, space 33 is formed between the glass plate 6a and the inner flange 2c2.

  Thus, by arrange | positioning the lower end of the holding member 31 so that it may not contact | connect the bottom face part 2c3 of the door frame 2c, there exists a clearance gap between the glass plate 6a and the front side flange 2c1, and the outer surface of the glass plate 6a from this clearance gap Even if water permeates when the water is wiped, the penetration of water into the holding member 31 is suppressed. For this reason, even when it does not have the protective film 19a, it can suppress that water adheres to the colored paint surface 19, and can suppress that it changes in color.

  Moreover, even if it has the protective film 19a, it is possible to prevent water from being sucked up by capillarity between the protective film 19a and the holding member 31, so that the waterproof property of the protective film 19a can be prevented from being deteriorated. Therefore, when the waterproof property of the protective film 19a is deteriorated, there is a possibility that water that has permeated the protective film 19a may permeate into the colored paint surface 19, but this can be prevented.

  Further, by inserting the holding member 31 using the enlarged portion 2c4 of the inner flange 2c2, that is, the inclination, there is an effect that the work can be performed smoothly and reliably and the deterioration and damage of the end portion of the holding member 31 are suppressed.

  Although the enlarged portion 2c4 of the above embodiment is configured with a linearly inclined surface, the holding member 31 is not in contact with the bottom surface portion 2c3 of the door frame 2c even if formed on a waved or stepped inclined surface. Support effect is obtained.

  It is desirable that these shrinkage rates are equal so that the holding member 31 and the vacuum heat insulating material 32 do not easily peel or deform. Further, the holding member 31 needs to have a strength capable of suppressing the deformation of the vacuum heat insulating material 32 due to a temperature change in the foaming heat insulating material (about 60 ° C.) or in a living environment.

  Furthermore, even when the vacuum heat insulating material 32 is disposed on the back surface of the glass plate 6a and the door is erected vertically as shown in FIG. 9 before the foam heat insulating material 7 is foamed, the holding member 31 is bent by the weight of the vacuum heat insulating material 32. A certain level of strength and thickness is required. For example, a cardboard, a PET film, or an iron plate having a thickness of about 0.3 to 0.4 mm is desirable as a material satisfying the shrinkage rate and strength.

  Further, as described above, the protective film 19a for protecting the colored paint surface 19 is provided on the back surface of the glass plate 6a. The end of the colored paint surface 19 is lower on the bottom surface 2c3 side of the door frame 2c than the upper end of the front flange 2c1 (in this embodiment, for example, the height of the front flange 2c1 is about 8 mm), and the front of the door When viewed from obliquely above, the end portion of the colored paint surface 19 is not visible, and is painted to a height position that does not contact the bottom surface portion 2c3 of the door frame 2c. If the thickness of the glass plate 6a is 3.0mm and the height of the front flange 2c1 is 8mm, the end of the colored paint surface 19 is not visible when viewed from obliquely above near the front of the door. It is within about 2 mm from the lower end surface 6a1 of the plate 6a.

  This is because if the outer surface of the glass plate 6a is wiped with water when the door is cleaned, water may enter from the gap between the glass plate 6a and the front flange 2c1, and the colored paint is applied to the bottom surface portion 2c3 of the door frame 2c. This is because when the end portion of the surface 19 is in contact, water enters from the contact portion and the colored paint surface 19 appears to be discolored or may be deteriorated.

  Therefore, by providing a distance of, for example, about 2 mm so that the bottom surface portion 2c3 of the door frame 2c and the end portion of the colored paint surface 19 do not come into contact with each other, even if water has entered, the infiltrated water does not enter the colored paint surface 19 Even if it does not contact or contacts, the contact dimension becomes small and the influence becomes small. In addition, since the contact size is small, the water level in the gap is lowered when the water is dried a little, so that it does not contact the lower end of the colored paint surface 19.

  The time until water does not contact the lower end of the colored paint surface 19 can be shortened. Therefore, it is possible to suppress the penetration of water into the colored paint surface 19. In this way, by suppressing the penetration of water into the colored paint surface 19, the light transmittance and reflectance when the water penetrates into the colored paint surface 19 may be partially different. It is suppressed. Thereby, it can suppress that a color looks partially different.

  Even if water does not penetrate into the colored paint surface 19, if the water overlaps the back side of the colored paint surface 19, it is unavoidable that the light transmittance and reflectance are partially different. Absent. Since the embodiment described above can also improve that water overlaps the back side of the colored paint surface 19, it can be suppressed that the color appears to change. In addition, when water penetrates into the colored paint surface 19 or when water overlaps the back side of the colored paint surface 19, the original color may not be restored even after the water dries, and the stain may remain. . Furthermore, when water does not dry for a long time, the paint itself may be deteriorated.

  However, as described above, according to the configuration of the example, the infiltrated water dries in a short time, and the time until the water level slightly drops and the water level slightly drops and the water does not contact the lower end of the colored paint surface 19 is short. Therefore, it is possible to suppress the drying of the water and remaining after the stain, or the deterioration of the paint itself.

  That is, when water that has entered from the gap between the door frame 2c and the glass plate 6a comes into contact with the end of the colored paint surface 19 and does not dry for a long time or for a long time, the water enters the paint from the surface of the paint. Will penetrate. Especially when the refrigerator has been used for many years after being purchased and exposed to direct sunlight or light such as ultraviolet rays, or after being exposed to oxidation in the air or harmful gases in the air for many years. May deteriorate and water may easily penetrate into the paint.

  The end surface of the protective film 19a provided so as to cover the colored paint surface 19 is provided to be within 2 mm from the lower end surface 6a1 of the glass plate 6a. That is, it is at a height position that covers the colored paint surface 19 and does not contact the bottom surface portion 2c3 of the door frame 2c. Incidentally, even if the lower end surface 6a1 of the glass plate 6a and the lower end of the protective film 19a contact | abut, you may affix until the lower end of the protective film 19a protrudes long from the lower end surface 6a1 of the glass plate 6a. That is, it is desirable that the colored paint surface 19 is completely covered by the protective film 19a.

  Thereby, when the outer surface of the glass plate 6a is wiped with water during the cleaning of the door, even if water enters from the gap between the glass plate 6a and the front flange 2c1, the colored paint surface 19 appears discolored or deteriorates. Deterioration can be suppressed.

Further, in the manufacturing process, small wrinkles are easily formed partially at the end of the protective film 19a. This wrinkle is because the protective film 19a is thin and soft, so that when the protective film 19a is applied to the glass plate 6a so as to cover the colored paint surface 19, a very slight variation or deviation in the attaching force, or attachment variations in speed, various conditions such as a temperature change is caused, partly in some cases creases Ru is formed at the end. This occurs to some extent in either automatic pasting by a machine or manual pasting by a skilled worker.

  When this wrinkle is large, water enters the gap between the wrinkle and the glass plate 6a. The size of this wrinkle is set to a dimension that extends in the center direction from the end side (periphery) of the protective film 19a to a small dimension within 2 mm. Thereby, a gap is not formed between the basket and the glass plate 6a or the gap is reduced, and it is possible to prevent water from entering the colored paint surface 19. For example, when the dimension between the lower end surface 6a1 of the glass plate 6a and the lower end of the protective film 19a is 1 mm, even if water enters from the gap between the door frame 2c and the glass plate 6a, It is usually difficult for a water amount to enter the water level to reach the lower end of the attached protective film 19a.

  Even if water enters until the water level reaches the lower end of the protective film 19a, if the size of the ridge generated at the lower end of the protective film 19a is within 1 mm, a gap is almost formed between the ridge and the glass plate 6a. In addition, since it is difficult for the air in the gap to be discharged, it is possible to prevent water from entering the gap.

  In addition, about the optimal dimension between the lower end surface 6a1 of the glass plate 6a mentioned above and the end surface of the protective film 19a, and the optimal dimension of the collar, it has been confirmed by experiment.

As described above, the refrigerator in the third embodiment takes into account the intrusion of water when the outer plate of the heat insulating door is made of glass, and even if water enters from the gap between the glass plate 6a and the door frame 2c, influence to eliminate or reduce the intrusion, the operation contents of the operation portion can be accurately detected.

  Furthermore, when water enters from the gap between the glass plate 6a and the door frame 2c, it is possible to suppress the colored paint surface from appearing to be discolored or from being altered to change the color.

  Further, even if water enters from the gap between the glass plate 6a and the door frame 2c, the water does not contact or contact the holding member that holds between the two members so that the paint protection member and the foam heat insulating material do not adhere to each other. However, by drying in a short time, the colored paint surface is prevented from appearing discolored or denatured to change color.

  Furthermore, in the case where the vacuum heat insulating material is disposed so as to be in contact with the glass plate 6a, the vacuum heat insulating material can be easily disposed at a predetermined position by attaching the vacuum heat insulating material to the holding member. And workability during recycling and dismantling can be improved.
