Known. Moreover, as said operation part, mechanism type switches, such as a micro switch, are known.

In addition, recent home appliances have used a capacitive touch switch. As an example of the refrigerator provided with a touch switch, there exists a thing of patent document 1. As shown in FIG.

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

Moreover, patent document 2 is mentioned as a refrigerator which comprised the outer board of the door surface by transparent plastic or glass, printed the operation part on the surface of this outer plate, and provided the display part on the back surface of this operation part. This presses the printed operation part by hand, and detects the magnetic field or body temperature produced by the hand, and displays the operation state on the display unit.

Patent Document 1: Japanese Patent Laid-Open No. 2006-304077 Patent Document 2: Japanese Patent Application Publication No. 2009-501311

However, in the structure described in Patent Literature 1, since the touch electrode protrudes toward the surface side of the operation panel, when the user operates the touch switch with a wet hand or finger, water is moved from the gap between the portion where the touch switch is installed.

The operation unit 9 sets the room temperature of each storage compartment such as the refrigerating compartment 2d and the freezing compartment 4d1, rapidly cools the refrigerating compartment 2d or the freezing compartment 4d1, or adjusts the size of the ice making by the user operating from the outside. Set it. In addition, it is provided in the refrigerating chamber 2d, the storage space is made into a reduced pressure or low oxygen state, the temperature of the storage chamber (not shown) which aims at maintaining the freshness of a stored food and suppressing oxidative deterioration is adjusted, and the function of reduced pressure or hypoxia can be adjusted. Set it to off. In other words, by operating the operation unit 9, various functions of the refrigerator can be set.

In addition, 10 is a display part. The display unit 10 displays the input result from the operation unit 9 on the outside of the refrigerator main body 1. Thereby, the operation which the user performed in the operation part 9 can be confirmed, or the state of the various functions set previously can be confirmed.

The operation part 9 and the display part 10 do not attach a special panel, but are provided in 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 flat across the outer surface of the left refrigerator compartment door 2a including the operation part 9 and the display part 10. As shown in FIG.

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

A colored paint is applied to the back surface of the glass plate 6a except for the display portion 10. Thereby, since the foam heat insulating material 7 is processed so that it cannot be seen from the front side, and the display part 10 is visually recognized clearly, the door which is excellent in external appearance is comprised.

Next, the operation unit 9 and the display unit 10 will be described in more detail with reference to FIG. 2.

In Fig. 2, the display of the character portions (each character of the frozen, refrigerated, ice-making, quenching, and vacuum chilled) surrounded by the broken lines is indicated by printing or the like directly on the back surface of the glass plate 6a. In addition, the operation part 9 refers to the thing of the front surface (front surface of the glass plate 6a which is the door front plate 6) of the position which opposes the back surface on which the said character part was printed. Moreover, besides printing, etching, inlay, etc. are mentioned as a means of providing the operation display (the said character part) on the back surface of the glass plate 6a.

2, the part enclosed by the solid line is the display part 10 which showed the setting state of various functions according to the input by the operation of the operation part 9 mentioned above. And this character display ("strong (low temperature), medium, weak", "strong (chilled), medium, weak", "bulk, standard, stop", "quick cooling, rapid freezing", "vacuum ice temperature, vacuum chilled") , Off (ice temperature)) is indicated by printing or the like on the film surface described later.

The film is adhered to the rear surface of the glass plate 6a which is the door front plate 6 with very little adhesion or gap. Therefore, the letter display can be clearly seen from the front of the left refrigerator compartment door 2a through the glass plate 6a. That is, the door which has high visibility and is excellent in external appearance by which the outer surface was comprised by the flat glass plate is comprised.

Moreover, the operation part 9 and the display part 10 are provided side by side up and down as shown in FIG. The display unit 10 is configured to display a function of the refrigerator main body 1 such that quenching or quenching is in operation.

In addition, the character display of the display part 10 is comprised so that it may be illuminated by LED (light emitting diode) etc. on a board | substrate mentioned later, light-transmitting to the front of the glass plate 6a, and appearing.

Next, in FIG. 3, 11 is a cover provided in the side of the left refrigerator compartment door 2a. The lid 11 is provided on the side opposite to the hinge of the left refrigerator compartment door 2a, and is provided between the adjacent right refrigerator compartment doors 2b. In this configuration, when the left refrigerator compartment door 2a and the right refrigerator compartment door 2b are closed, the lid 11 is invisible to the user.

Next, in FIG. 4, 2a is a left refrigerator compartment door, 6 is a door front plate, 7 is foam insulation, 8 is a door inner plate, and 12 is a board | substrate assembly. The substrate assembly 12 includes an LED light emitting unit 13 for illuminating the display unit 10, a detection unit 14 for detecting a change in capacitance, a determination unit (not shown), and an automatic control unit (not shown) including a microcomputer. The board | substrate 15 provided, etc., the film 16 on which display characters were printed, the board case 17, etc. are comprised.

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

The detection part 14 is paired with the operation part 9 at the time of assembly to the left refrigerator compartment door 2a. That is, as shown in FIG. 4, through the glass plate 6a and the film 16 which are insulators, the operation part 9 overlaps with the front side so that the detection part 14 may be in the back surface side.

In addition, the determination unit (not shown) detects the capacitance change between the operation unit 9 and the detection unit 14 in the substrate 15. When there is a change in capacitance, an oscillation circuit including oscillation and amplitude changes in accordance with the change in the capacitance. Thereby, the automatic control part which took out the switch signal and the ON / OFF signal which the determination part outputs drives a load. In addition, the user does not output the switch signal or the on / off signal that the determination unit outputs by simply passing the user in front of the operation unit 9 or wiping the front of the refrigerator (left refrigerator door 2a) for cleaning. I do not do it.

That is, the glass plate 6a which comprises the door front plate 6 of a refrigerator is an insulator, and is a translucent board | plate material. And in order to make the front surface of the glass plate 6a into the operation part 9, the operation content of the operation part 9 is displayed by the character shown by printing etc. on the back surface of the operation part 9 of the glass plate 6a.

On the rear surface of the glass plate 6a opposite to 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 via the film 16. Character display, such as the display part 10 provided in parallel with the operation part 9, is shown by printing etc. on the surface of the film 16 which covers the surface of the board | substrate 15. FIG.

And the character display of the display part 10 is specified from the back surface by the LED light emitting part 13 provided on the board | substrate 15. As shown in FIG. In addition, when a hand or a finger contacts the operation unit 9, the detection unit 14 on the substrate 15 detects a change in capacitance between the glass plate 6a and the determination unit on the substrate 15. Informed. And when a determination part detects an input, it operates a load through an automatic control part.

Here, the load operated through 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) in the case of rapid cooling, or a forced "open" control of a damper controlling the amount of cold air supplied. By controlling these loads, the refrigerating chamber 2d is quenched or the freezing chamber 4d1 is quenched.

When the detection part 14 which detects the change of capacitance is provided in the board | substrate 15, and the determination part judges the change of capacitance, the buzzer provided in the board | substrate 15 will generate a notification sound, A note scale is attached to the notification sound according to the change.

The above is explained concretely using FIG. When the temperature of the refrigerating chamber 2d or the freezing chamber 4d1 is adjusted to a setting of "strong, medium, or weak", in the present embodiment, a sound scale is applied to the notification sound by the following cycle.

`` Weak (low) '' → `` mid '' (mid) `` strong '' (high) `` sol '' → `` low '' 」. Thus, even when a user who cannot see the text is operated, the temperature setting can be confirmed by the difference in the scale.

In addition, the optional additional functions such as quenching and quenching, when input, change the scale and the number of notifications to the notification sound by the following cycle.

`` Quick freezing (bass '') → quenching (medium `` mi '') → quenching and quenching (high) `` sol '' → stop (high two times `` la, la '') → quenching (low) )… 」.

In particular, in the case where no additional function is selected (stop), as described above, by setting the number of notification sounds as plural times, the user can easily confirm the setting contents by hearing without recognizing the time.

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. Moreover, the board | substrate preparation 12 serves to hold | maintain the board | substrate preparation 12 in the case cover 18 so that the film 16 of the surface of the board | substrate 15 may be close to or close to the glass plate 6a which is the door front plate 6. As shown in FIG.

19 shows the colored coating surface implemented on the back surface of the glass plate 6a. The colored paint surface 19 is provided on the whole rear surface of the glass plate 6a except the display part 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. In addition, this protective film 19a is affixed on the same surface as the colored paint surface. Thereby, the foam heat insulating material 7 peeps out from the door front side, and is preventing the appearance damage.

In addition, the short side direction of the board | substrate preparation 12 and the short side direction of the glass plate 6a are arrange | positioned so that it may cross | intersect. This is based on the property that the distortion of the glass plate 6a tends to appear in the long side direction when heat treatment is applied to the glass plate 6a. That is, in consideration of this property, it is set as the structure which suppresses the influence of the distortion of the glass plate 6a at the time of installing the board | substrate preparation 12.

Here, in the long side direction of the glass plate 6a, when assembled so that the long side direction of the board | substrate preparation 12 may follow, the glass plate 6a and the board | substrate 15 may be influenced by the distortion of the glass plate 6a. The gap tends to be formed between the detection units 14. Thereby, the problem that the input content from the operation part 9 does not convey well to the detection part 14 arises.

Therefore, in this embodiment, the long side direction of the board | substrate article 12 is arrange | positioned in the direction which cross | intersects the long side direction of a glass plate.

Moreover, manufacturing cost can be reduced by making the door surface of a refrigerator into the glass plate 6a of 1 sheet. In addition, the clearance between the glass plate 6a and the detection part 14 needs to be 0.2 mm or less including the distortion of the glass plate 6a. When the clearance gap of 0.2 mm or more arises, it turns out by the test etc. of this inventor that the subject that the input content from the operation part 9 does not convey well to the detection part 14 arises.

Moreover, the board | substrate preparation 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 out of reach of small children. Moreover, it becomes a position which is easy to see and operate for a user.

In addition, in the case of this embodiment, the operation part 9 and the display part 10 do not protrude from the door front plate 6 like conventionally. Thereby, it is difficult for a small child to recognize itself that the operation part 9 and the display part 10 are there. In other words, mischievous manipulation by a child can be reduced.

Thereby, when the board | substrate case 17 is assembled in the case cover 18, the convex part 17b acts so that the curvature of a board | substrate case may be correct | amended. Therefore, the detection part 14 on the board | substrate 15 can be provided so that it may be in close_contact | adherence to or close to the glass plate 6a.

In addition, as shown in FIG. 7, a plurality of ribs 18a are provided on the back surface of the case cover 18. That is, the some rib 18a is provided in the side which contact | connects the foam heat insulating material 7. As shown in FIG.

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

As described above, since the case cover 18 can be suppressed from being deformed or deviated by the filling foaming of the foamed heat insulating material 7, the guide groove 25 when assembling the substrate rough product 12 into the case cover 18. ) And the slide member 20 can be restrained from being misaligned. That is, it can be provided so that the detection part 14 on the board | substrate 15 may be closely_contact | adhered to or close to the glass plate 6a.

Next, the case where the board | substrate preparation 12 is assembled in the space 26 formed by the glass plate 6a and the case cover 18 is further demonstrated, referring FIG.

The slide member 20 on the inlet part 25b side is lightly pushed along the guide groove 25 in the state located in the inlet part 25b of the guide groove 25. Then, the slide member 20 on the side of the end portion 25a arrives at the end portion 25a of the guide groove 25, and the detection portion 14 (see FIG. 4) of the substrate assembly 12 is the film 16. Through or close to the glass plate 6a.

As shown in FIG. 6, the slide member 20 on the side of the inlet portion 25b rides on the guide portion 25c from the inlet portion 25b, and the fixing portion 23 provided on the substrate case 17 has an elastic force. It resists and stops over the stopper 27, and is fixed to the stopper 27. Thereby, the board | substrate article 12 is fixed in the state which the detection part 14 adhere | attached or adjoined to the glass plate 6a which is the door front plate 6 through the film 16. As shown in FIG.

Next, the board | substrate side connector 22 is located in the insertion part 24 side. As shown in FIG. 7, the cable wire 28, such as a power cord, is previously drawn out in 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 board side connector 22. As shown in FIG. As a result, the cable lines 28 can be arranged in the space 26. In this state, the cover 11 is attached and the assembling work is completed. In addition, what is necessary is just to perform the operation opposite to the above, in the case of removing the board | substrate preparation 12 at the time of inspection and repair.

In addition, the cable wire 28 is drawn out to the space 26 from the foam heat insulating material 7 side of the door 2. The outlet 30 to the space 26 is provided near the lid 11 as shown in FIG. 6. Thereby, the arrangement | work of the cable wire 28 becomes efficient.

In addition, the outlet 30 is located above the space 26 when the left refrigerator compartment door 2a is assembled to the refrigerator main body 1. Thereby, the dew condensation water adhering to the space 26 can be prevented from invading into the foam heat insulating material 7 side from the outlet 30.

Moreover, when forming the display part 10 by the direct printing etc. on the back surface of the glass plate 6a, and setting it as the structure which removes the film 16, the following subject arises. In the process of filling the foam heat insulating material 7, the position shift of the display part 10 and case cover 18 provided in the glass plate 6a by about foaming pressure produces about 1 or 2 mm. That is, since the board | substrate preparation 12 is positioned by the guide groove 25 provided in the case cover 18, it is positioned between the LED light-emitting part 13 provided on the board | substrate 15, and the display part 10. FIG. There is a deviation. Therefore, illumination nonuniformity generate | occur | produces in the display part 10, and it is not preferable in appearance. In addition, it is not preferable to enlarge the character display part in view of the positional shift.

That is, since the board | substrate preparation 12 is comprised from the board | substrate case 17, the board | substrate 15, the film 16, etc., even if the case cover 18 displaces in the process of filling the foam heat insulating material 7, This is a configuration in which illumination irregularity of the display unit 10 is unlikely to occur.

In this embodiment, the glass substrate 12 is made of a glass plate in relation to the four slide members 20 provided on the substrate case 17 and the guide grooves 25 provided on the case cover 18. The structure in close contact with (6a) has been described. However, this is an example for bringing the detection unit 14 into close contact with the glass plate 6a and is not limited to this configuration. In addition, the position which installs the insertion part 24 is not limited to the door side mentioned above, The door bottom surface, an upper surface, or the back surface (foam insulation material side) may be sufficient.

Next, in FIG. 8A, the substrate assembly 12 is composed of a substrate case 17, an LED light emitting unit 13, a substrate 15, a film 16, and the like. The substrate 15 is stored in the recess 21 of the substrate case 17. Moreover, the surface 15a of the board | substrate 15 is accommodated so that it may become coplanar with the flange part 17a provided in the board | substrate case (board | substrate accommodation member) 17. As shown in FIG. In this state, the adhesive film 16 is tightly fixed to the surface 15a of the substrate 15 and the flange portion 17a of the substrate case 17.

Therefore, the space portion does not exist or is adjacent between the detection portion 14 and the film 16 on the substrate 15.

Next, the configuration of the LED light emitting portion 13 will be described with reference to FIG. 8B. The LED 13b is disposed on the opposite side of the detector 14 of the substrate 15. In the vicinity of the LED 13b, a hole 15b is provided. In the hole part 15b, the LED light projection part 13a is provided. The film 16 is arrange | positioned at the opposing surface of the hole part 15b.

As a result, when the LED 13b is turned on, the light is incident on the source 13c of the LED light projecting portion 13a disposed on the opposite surface of the LED 13b. The LED light-transmitting part 13a is injection-molded with the transparent resin of polystyrene, the transparent resin material of acryl, etc. Therefore, as shown by the arrow of FIG. 8B, the inside of the LED light-projection part 13a is refracted and light-transmitted, and the surface 13d of the LED light-projection part 13a is lighted. Thereby, it is the structure which lightens the display character of the film 16.

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

According to this structure, the thickness of the board | substrate case 17 which embedded the board | substrate 15 can be minimized, and the thickness of the foam heat insulating material 7 can be ensured enough.

And although it is not shown in figure, when it turns on by the automatic control part, the display part 10 is illuminated on the back surface side of the film 16, it penetrates through the glass plate 6a, and makes it easy to see a character.

In other words, the LED light emitting unit 13 in the present embodiment is turned on only when the detection unit 14 detects the capacitance. Then, in the actual use state, it is difficult for the small child to recognize that the glass plate 6a itself is the operation unit 9. Thus, mischief or the like can be prevented.

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

The lighting of the LED light emitting part 13 is performed as follows. That is, the detection part 14 detects this when the user touches a finger etc. with the operation part 9 of the character part shown on the front surface through the glass plate 6a. Then, the determination unit and the automatic control unit operate, for example, when rapid cooling is instructed, the lamp is turned on to illuminate the character portion of the "cooling refrigerator" of the display unit 10.

Since this invention has the structure of each Example demonstrated above, the following effects are acquired.

That is, the door front plate of a refrigerator is made into the glass member which has insulation and light transmittance. Then, the front surface of the glass member is used as a plane-shaped operation portion, and a character display portion in which printing or the like is printed on the rear 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 each other, and a character display such as a display unit for displaying the operation result is provided near the operation unit. In addition, the character display of this display part is irradiated from the back by the light emitting diode etc. which were provided in the board | substrate.

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

As a result, since the door front plate becomes an insulator and is made of a light-transmissive glass plate, the operation portion that touches the touch electrode becomes the glass front surface, thereby making the operation panel unnecessary. In addition, when the glass whole surface is contaminated by moisture, oils, etc., since the said glass whole surface is planar shape, it can simply wipe off. In addition, it is possible to suppress the mischief of children. Moreover, even if a user may touch the operation part with the hand or the finger | toe with a water or fat or oil content, since an operation part is a glass member itself, corrosion and deterioration of an electrical component can be suppressed. In addition, since the door surface is flat, it is easy to mop.

Moreover, the display part provided in parallel with an operation part is projected from the back by LED etc. according to the instruction | indication of the automatic control part on a board | substrate, and is projected on the glass member surface.

As a result, the user can check the contents input by himself / herself on the display of the door surface without opening or closing the door, so that incorrect input or unnecessary door opening and closing can be prevented.

The substrate further includes an LED light emitting unit for illuminating the display unit, a detecting unit detecting a change in capacitance, an automatic control unit including a determination unit and a microcomputer. Moreover, the board | substrate is covered with a film and a board | substrate case, and it is provided so that a film may contact or approach a detection part, and a detection part may contact or approach a glass plate through a film.

Thereby, the positional relationship of an operation part and a determination part is kept constant, and the microcomputer etc. are protected by the film and the board case, and the possibility of being damaged is reduced. In addition, when attaching a board | substrate case, there is no possibility that a back surface of a glass member may be damaged by a board | substrate case.

Moreover, the board | substrate case containing a board | substrate is accommodated in the case cover isolate | separated from foam insulation, and the film which contacts or approaches the detection part provided in the board | substrate is attached so that a detection part may contact or approach the back surface of a glass member.

Thereby, the board | substrate assembled in the board | substrate case can be prevented from failing by the invasion of the foam heat insulating material to be filled.

Moreover, a colored paint is provided in the back surface of glass members other than a display part.

As a result, the transparency of the display portion is maintained, and the glass protective material, the foamed heat insulating material, and the like attached to the rear surface of the glass are not seen from the front of the door, so that the appearance is satisfactory.

The substrate further includes an LED illuminating the display portion, a detecting portion detecting a change in capacitance, an automatic control portion including a determining portion and a microcomputer, and the detecting portion being disposed on the substrate surface on the door surface side. The LED for illuminating the display unit is disposed on the opposite side of the substrate on which is disposed. Moreover, a corner hole is provided around the board | substrate which arrange | positioned LED, and a display part is provided in the opposing surface of the said corner hole.

Thereby, the thickness of the board | substrate case which integrated the board | substrate can be reduced, and the thickness of foam insulation can fully be ensured.

The glass member has a planar shape that is long in the height direction, and the substrate has a horizontally long shape, and the long side direction of the substrate crosses the height direction of the glass member. In addition, the thickness of a glass member shall be 2 mm-3.5 mm.

Thereby, the glass plate can be prevented from being cracked or cracked when the foam insulation is filled, when the refrigerator is used, and when the refrigerator is assembled. Moreover, the influence of heat deformation of the glass itself, etc. can be suppressed to the minimum. In addition, manufacturing costs can be reduced.

In addition, the reason for making thickness of a glass member into 2 mm-3.5 mm is as follows. That is, the impact that the glass member serving as the door front plate receives when the foam insulation is filled, when the refrigerator is used, when the refrigerator is assembled, and when the refrigerator is transported is considered. Specifically, when the 1 kg copper ball is dropped from the height of 1 m above the door, the glass member is secured not to be broken.

In addition, in order to ensure the further strength, you may add a heat strengthening process or a chemical strengthening process to a glass member. In addition, in order to reduce the mass of the refrigerator itself, the thinner is preferable if the thickness of the glass member can ensure only strength.

In the present embodiment, as described above, a protective material is attached to the rear surface of the glass member so that the fragments do not scatter even if the glass member is broken. In addition, when the reinforcing treatment is applied, the fragments of the glass become small, and the safety can be improved.

In addition, 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 by a detection part.

Moreover, when the detection part which detects the change of electrostatic capacitance is provided in the board | substrate, and the determination part judges the change of electrostatic capacity, the buzzer which is a notification means provided in the board | substrate produces a notification sound. In addition, the notification sound provides a scale for the notification sound according to the change of the control content or changes the number of notification sounds.

In this way, when the user performs an operation, the contents input by the sound can be confirmed by the scale of the notification sound and the number of notification sounds. Since the door surface plate of a refrigerator is comprised by the glass member without an unevenness | corrugation, and the flat operation part is provided, it becomes important to be able to confirm the content by sound.

In addition, when assembling the substrate assembly into the case cover from the insertion portion provided in the door, the surface of the substrate assembly is in contact with the rear surface of the glass plate in relation to the guide groove and the termination portion provided in the case cover and the slide member provided in the substrate cover. Or close.

Thereby, board | substrate preparation can be accommodated, without damaging the determination part and the glass plate back surface. Moreover, attachment and detachment of a board | substrate product is attained with small force.

Moreover, the board | substrate is detachably mounted in a case cover from the insertion part provided in the side surface, the top surface, or the bottom surface of a door, and a insertion part is closed by a cover.

This makes it difficult for the user to visually recognize the insertion portion, thereby enabling the design to be excellent in design. Moreover, the service inspection of the board | substrate goods can be performed by opening and closing of a cover, without removing a door from a refrigerator main body.

In addition, the board is detachably mounted in the case cover from the edge portion of the door, that is, the insertion portion provided on the side, top or bottom, and the connector of the cable wire drawn out in the case cover is attached to the board-side connector after the board is mounted. Connect.

This facilitates the connection and storage work of the cable line.

Further, the fixing portion formed integrally with the resin substrate case is elastic, and the fixing portion is fixed to the stopper on the case cover side by using the elasticity to fix the substrate case in the case cover.

Thereby, when an impact is applied to the refrigerator main body, the position of the substrate assembly mounted in the case cover is prevented from shifting, and the detection unit is prevented from detecting the change in the electrostatic capacity.

Example 3

Next, Example 3 will be described with reference to FIGS. 9 and 10. In addition, about the component same as Example 1 and 2, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted. In addition, although it demonstrates using a left refrigerator compartment door, other doors are also substantially the same except the presence of an operation part and a display part.

The door of the refrigerator in this embodiment also includes a glass plate 6a, which is a door front plate having light transparency on its outer surface. This glass plate 6a is accommodated in the accommodating part provided in the door frame 3. This storage part is comprised from the front flange 2c1 and the inner flange 2c2. In the example of embodiment, it fits in the inner flange 2c2 and the front flange 2c1, and the lower end part is supported.

The colored paint surface 19 is provided in the back surface of the glass plate 6a. On the surface of the colored paint surface 19, the waterproof protective film 19a which is a paint protection member is stuck. Thereby, even if water penetrates from the clearance gap between the glass plate 6a and the front side flange 2c1, it will protect so that the moisture which penetrated may not penetrate the colored paint surface 19. FIG.

The protective film 19a used the vinyl chloride sheet. This is, the adhesive strength between the foamed insulating material (7) iron plate is lower to about 8N / ㎜ ^2, ABS is about 4 ~ 6N / ㎜ ² so, the vinyl sheet is 2.4 ~ 3.3N / ㎜ chloride ^2. As a result, the glass plate 6a is easily separated from the foam insulation. That is, since the protective film 19a has a weak adhesiveness with the foam heat insulating material 7, the glass plate 6a can be easily removed from the door and removed when the refrigerator is dismantled. It is good to use a thing with low adhesive strength with). Specifically, when dismantling the refrigerator to be disassembled in a recycling center or the like, it becomes easy to fractionate and remove only the glass plate 6a as a recycling material.

Moreover, the holding member 31 is sandwiched between the said protective film 19a and the foam heat insulating material 7, and it hold | maintains between both members so that the protective film 19a and the foamed heat insulating material 7 may not adhere | attach. Thereby, in order to suppress that the high temperature heat at the time of foaming the foam heat insulating material 7, and various influences by the viscosity, foaming pressure, time-lapse, etc. when this high temperature foam heat insulating material flows, are transmitted to the protective film 19a. I can keep it.

Moreover, between the protective film 19a and the foam heat insulating material 7, the vacuum heat insulating material 32 is affixed to the said holding member 31 by adhesive means, such as an adhesive tape and a hot melt (not shown). Thereafter, the foamed heat insulating material 7 is fixed to the predetermined position. That is, the holding member 31 is inserted and arrange | positioned so that the vacuum heat insulating material 32 and the glass plate 6a may adjoin.

The vacuum heat insulating material 32 attached to this holding member 31 is arrange | positioned so that the holding member 31 may be sandwiched between the surfaces of the protective film 19a (protective film 19a and holding member 31 are not adhesively fixed). Do not). This is because when the vacuum insulator 32 is directly attached to the surface of the protective film 19a with an adhesive tape, it is difficult to peel off, and the efficiency of dismantling work during recycling becomes worse.

By inserting the said holding member 31, the vacuum heat insulating material 32 and the protective film 19a do not adhere | attach, the glass plate 6a provided with the colored paint surface 19 and the protective film 19a, and a vacuum The heat insulating material 32 makes it easy to separate.

The lower end of the holding member 31 uses an enlarged portion 2c4 in which a gap extends toward the upper end of the inner flange 2c2, and is formed between the inner flange 2c2 and the front flange 2c1 together with the glass plate 6a. It is stored and supported. At this time, the holding member 31 is disposed not to be in contact with the bottom portion 2c3 of the door frame 2c. Thereby, the space 33 is formed between the holding member 31 and the bottom part 2c3 of the door frame 2c, and between the glass plate 6a, the inner flange 2c2, and the door.

Thus, by arrange | positioning the lower end of the holding member 31 so that it may not contact the bottom face part 2c3 of the door frame 2c, there exists a clearance between the glass plate 6a and the front side flange 2c1, and this glass plate from this clearance Even if water intrudes when the outer surface of (6a) is wiped with water, 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 discoloration further.

Moreover, even if it has the protective film 19a, since sucking up water by capillary phenomenon between the protective film 19a and the holding member 31 is suppressed, deterioration of the waterproofness of the protective film 19a can be suppressed. . Therefore, when the waterproofing property of the protective film 19a deteriorates, there exists a possibility that the water which penetrated the protective film 19a may penetrate into the inside of the colored paint surface 19, but this can be prevented.

In addition, by inserting into the holding member 31 using the enlarged portion 2c4 of the inner flange 2c2, that is, the inclination, smooth operation can be reliably performed and deterioration of the end of the holding member 31 is performed. It has the effect of suppressing damage.

On the other hand, although the enlarged part 2c4 of the said Example comprised with the linear inclined surface, even if it forms in the wave-shaped or staircase inclined surface, the holding member 31 contacts the bottom part 2c3 of the door frame 2c. A supporting effect is obtained so as not to.

It is preferable that these shrinkage ratios are equivalent so that the holding member 31 and the vacuum heat insulating material 32 do not easily peel or deform. In addition, the holding member 31 is required to have a strength capable of suppressing the deformation of the vacuum insulator 32 due to the temperature change at the time of foaming the insulator (about 60 ° C.) or the living environment.

Moreover, even when the vacuum heat insulating material 32 is arrange | positioned at the back surface of the glass plate 6a, and the foam heat insulating material 7 is erected upright as shown in FIG. 9 before foaming, the holding member (with the weight of the vacuum heat insulating material 32) ( 31) Strength or thickness is necessary to prevent bending. As what satisfy | fills conditions, such as a shrinkage rate and intensity | strength, cardboard, PET film, the iron plate of about 0.3-0.4 mm in thickness, etc. are preferable, for example.

Moreover, the protective film 19a for protecting the colored paint surface 19 is provided in the back surface of the glass plate 6a as mentioned above. The end of the colored paint surface 19 is the bottom portion 2c3 of the door frame 2c than the upper end of the front flange 2c1 (in this embodiment, for example, the height dimension of the front flange 2c1 is about 8 mm). When viewed from the lower side and the front inclined upper side of the door, the end of the colored paint surface 19 is not seen and painted to a height position not in contact with the bottom portion 2c3 of the door frame 2c. ) When the thickness dimension of the glass plate 6a is 3.0 mm and the height dimension of the front flange 2c1 is 8 mm, it is not seen that the edge part of the colored paint surface 19 is not seen from the inclined upper direction close to the front door. It is less than about 2 mm from the lower end surface 6a1 of the board 6a.

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

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

The time until water does not come into contact with the lower end of the colored paint surface 19 can be shortened. Therefore, the penetration of water into the colored paint surface 19 can be suppressed. In this way, by preventing the water from penetrating into the colored paint surface 19, the partial change in the transmittance and reflectance of light when water penetrates into the colored paint surface 19 is suppressed. Thereby, it can suppress that a color looks partially different.

In addition, even if water does not penetrate inside the colored paint surface 19, when water overlaps the back side of the colored paint surface 19, it cannot be avoided that the light transmittance and reflectance partially vary. Since the said embodiment can improve that water overlaps on the back side of this colored paint surface 19, it can suppress that a color changes. In addition, when water penetrates inside the colored paint surface 19 or when water overlaps the back side of the colored paint surface 19, even if the water dries, the stain may remain afterwards without returning to the original color. . Even if the water does not dry for a long time, the paint itself may be deteriorated.

However, as described above, according to the constitution of the embodiment, the time until the intruded water dries in a short time and at the same time dries a little so that the water level is lowered slightly so that the water does not come into contact with the lower end of the colored paint surface 19 Since it becomes a short time, it is possible to suppress that a water dries and a stain remains afterwards, or the deterioration of paint itself.

That is, when the water penetrated 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 is in contact with it without being dried for a long time or for a long time, the inside of the paint is painted from the surface of the paint. Penetrates into. In particular, when the refrigerator has been in use for several years after the refrigerator has been faded for a long time to direct sunlight or ultraviolet light, or has been used for a long time to oxidize by oxygen in the air or harmful gases in the air, the paint may deteriorate. There exists a possibility that water may permeate easily into paint.

The end surface of the protective film 19a provided so that the colored paint surface 19 may be covered is provided so that it may become within 2 mm from the lower end surface 6a1 of the glass plate 6a. That is, it is set as the height position which covers the colored paint surface 19 and does not contact the bottom face part 2c3 of the door frame 2c. In this connection, even when the lower end 6a1 of the glass plate 6a and the lower end of the protective film 19a contact, the lower end of the protective film 19a protrudes long from the lower end 6a1 of the glass plate 6a. You may stick until you do. That is, it is preferable that the colored paint surface 19 is completely covered with the protective film 19a.

Thereby, even when water intrudes from the clearance gap between the glass plate 6a and the front side flange 2c1, when the outer surface of the glass plate 6a was wiped with water at the time of the door cleaning, the colored paint surface 19 discolors. It can be suppressed from deterioration or deterioration.

In addition, in the manufacturing process, small wrinkles are likely to partially occur at the ends of the protective film 19a. Since the wrinkles are thin and flexible, when the protective film 19a is attached to the glass plate 6a so as to cover the colored paint surface 19 with the protective film 19a, the gap and shift of the very small adhesion force are very small. Or wrinkles may be partially formed at the end due to various conditions such as gaps in sticking speed and temperature changes. This occurs to some extent in either case of automatic pasting on a machine or pasting by hand of an experienced worker.

When the wrinkles are large, water enters the gap between the wrinkles and the glass plate 6a. The size of this wrinkle is made into the small dimension within 2 mm which extends to the center direction from the end side (periphery) of the protective film 19a. Thereby, a gap is not formed between a wrinkle and the glass plate 6a, or a clearance becomes small and it can suppress that water penetrates into the colored paint surface 19. FIG. 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, water penetrates in the clearance gap between the door frame 2c and the glass plate 6a. Even if it is, even if water quantity invades so that it may become the water level which touches the lower end of the protective film 19a attached to the back surface of the glass plate 6a, it is hard to occur normally.

For example, even if water penetrates until the water level reaches the lower end of the protective film 19a, if the dimension of the wrinkles generated at the lower end of the protective film 19a is within 1 mm, between the wrinkles and the glass plate 6a. Since the gap is hardly formed and the air in the gap is hard to be discharged, it is possible to suppress water from entering the gap.

Moreover, about the optimal dimension between the lower end surface 6a1 of the glass plate 6a mentioned above, and the cross section of the protective film 19a, and the optimal dimension of a wrinkle, confirmation was confirmed by experiment.

As mentioned above, the refrigerator in Example 3 considers the intrusion of water when the outer plate of the heat insulation door is made of glass, and even if water intrudes from the clearance gap between the glass plate 6a and the door frame 2c, With little or no influence, the operation contents of the operation unit shown on the display unit can be detected accurately.

Even when water penetrates from the gap between the glass plate 6a and the door frame 2c, the colored paint surface may be discolored, or it may be suppressed from being changed to change color.

In addition, even if water penetrates from the gap between the glass plate 6a and the door frame 2c, even if the water does not contact or comes in contact with the holding member held between the two members so that the paint protection member and the foamed heat insulating material do not adhere. By making it dry in a short time, it can suppress that a colored paint surface looks discolored, or changes color and changes color.

Even in disposing a vacuum insulator in contact with the glass plate 6a, by attaching a vacuum insulator to the holding member, it is easy to arrange the vacuum insulator at a predetermined position, thereby improving workability and recycling. Workability can be improved.
