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 refrigerating cycle, a forced continuous operation of a cold air circulation fan (not shown), or a forced open control of a damper that controls the amount of cold air supply when quenching is performed. 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 preparation 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.

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 about 1 mm-2 mm arises in the display part 10 and case cover 18 which were provided in the glass plate 6a by foaming pressure. 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. A film 16 is disposed on the opposite surface of the hole portion 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 installed.

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.

Next, with reference to FIG. 9, the example which provided the insertion part 24 in the door bottom surface is demonstrated. In FIG. 9, the insertion part 24 is provided in the bottom face of the left refrigerator compartment door 2a, and the cover part 11 covers the insertion part 24. As shown in FIG. Here, in view of operability and visibility, the display part 10 is provided next to the handle 1a which opens and closes the left refrigerator compartment door 2a. Therefore, the insertion part 24 is made into the bottom face of the left refrigerator compartment door 2a.

In addition, the installation method of the display part 10 and the operation part 9 (not shown), the assembly method of the board | substrate preparation into the left refrigerator compartment door 2a, etc. are the same as the above description.

In this case, the lid 11 can be further lowered by being lower than the eye of the user.

In addition, although not shown, when the overall height of the refrigerator main body 1 is low, the one which arrange | positioned the display part 10 on the upper part of the refrigerator compartment door is good to use. That is, the structure which provided the insertion part 24 in the upper surface of a door is also possible. Also in this case, the assembly method of a board | substrate article is the same as the above.

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.

Thereby, transparency of a display part is maintained, and the glass protective material, foam insulation, etc. which were affixed on the glass back surface are not seen from the front of a door, and let it be favorable in appearance.

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 connection and storage 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.
