Description

refrigerator

The embodiment relates to a refrigerator.

In the refrigerator, there is a product in which a touch panel is placed on the door instead of an operation button, and many proposals have been made regarding a refrigerator having a touch panel. Patent Document 1 discloses a refrigerator including a door front panel made of a glass plate, a plurality of operation portions located at a front surface of the door front panel, and a detection portion disposed at a rear side of the door front panel and corresponding to the operation portion. And detecting the electrostatic capacitance; the display unit displays the operation result; the illumination device irradiates the light to the display unit from the rear; and the control unit.

In the conventional refrigerator, the substrate assembly is provided so that the longitudinal direction (longitudinal length) of the glass plate is orthogonal to the longitudinal direction of the substrate assembly (including the detecting portion, the display portion, the illumination device, the control portion, and the like, left and right). Thereby, the bending of the glass sheet at the time of the operation of the operation portion is reduced. Further, by disposing the substrate assembly at a position away from the lower end of the door, water is prevented from infiltrating from the lower end of the glass plate to affect the substrate or the like.

However, in the conventional refrigerator, in the capacitive touch panel having a plurality of operation portions, there is a possibility that the detection portion corresponding to each operation portion and the glass plate are When the gap is formed and the detection accuracy is lowered, it is necessary to make all the detecting portions reliably approach the structure of the glass plate.

Further, in the conventional refrigerator, the substrate assembly is disposed such that the longitudinal direction of the glass plate is orthogonal to the longitudinal direction of the substrate assembly, so that the bending of the glass plate does not affect the detection accuracy of the detecting portion. However, a touch panel configuration that can improve the detection accuracy regardless of the orientation of the substrate assembly is required.

The outer panel 31 is translucent, but is processed so that the inner heat insulating material 33 and the like cannot be viewed from the outside. A capacitive touch panel is disposed in the first door 21 of the refrigerating compartment.

Hereinafter, the configuration of the touch panel will be described in detail.

As shown in FIGS. 3 to 7 , the touch panel unit 40 is disposed in the first door 21 of the refrigerating compartment so that the longitudinal direction thereof is parallel to the longitudinal direction of the first door 21 of the refrigerating compartment.

The touch panel unit 40 is formed by sequentially operating the nameplate 41, the flexible substrate 42, the pressing member 43, the supporting member 44, and the operation substrate 45 from the front. The state in which each layer has a layer is accommodated in the storage box 47.

The storage box 47 is temporarily fixed to the outer panel 31 by the edge portion 86, and is fixed in advance in a state where the heat insulating material 33 is pressed against the outer panel 31 at a predetermined position when the heat insulating material 33 is filled and foamed. position.

Hereinafter, for the sake of explanation, the upper side in FIG. 5 is set to the upper side, the lower side is set to the lower side, the right side is set to the right side, and the left side is set to the left side. The operation nameplate 41 is formed of a light-shielding sheet, and is formed such that a portion in which characters, patterns, and the like are displayed is transparent (having light transmissivity), and if the light is irradiated from the back surface, the characters drawn in the portion are The pattern and the like float. That is, as shown in FIG. 8, the operation nameplate 41 includes a transmissive portion 54 for displaying characters, patterns, and the like. On the operation nameplate 41, an operation menu such as "refrigeration", "frozen", "freeze function", "ice making", "power saving", "key lock" (in order 51a~51f) is provided ( Menu) 51, or "immediate freezing", "hot food freezing", "vegetable refrigeration", "dry", "instant ice making", "ice making closed", "power saving", "going out", " The report menu 52 of the refrigerator 1 state is reported as the transmissive portion 54 of the peak shift.

The light of the light-emitting diode 91 passes through a cylindrical reflector (light path portion) that guides light by enclosing the light of the concave portion 71a to the concave portion 71e within a predetermined range, and the light-emitting diode is operated by operating the transmitting portion 54 of the nameplate 41. The light of the body is transmitted to the front. On the other hand, the light of the light-emitting diode of the reflecting member in the opaque portion is reflected and returned to the concave portion 71a, and the light that is again reflected to the wall surface of the concave portion 71a is guided to the front, and the reflected light is passed through the transmitting portion 54. To the front. Thereby, more light passes through the transmissive portion 54, and characters, patterns, and the like can be displayed clearly and contrastably.

Further, since the concave portion 71a has an inverted conical shape, it is easy to concentrate the reflected light at the center, and the light is easily concentrated on the transmissive portion 54 which is described as the center of the portion corresponding to the concave portion 71a of the operation nameplate 41, and thus more The light passes through the transmissive portion 54. Therefore, characters, patterns, and the like can be displayed clearly and with good contrast. In this case, a reflecting member may be provided on the wall surface of the concave portion 71a, or the wall surface of the inverted conical surface may be a curved surface to further improve the light collecting efficiency.

The reflecting plate 61 has a function of reflecting light irradiated from the front, and has a function from the back The emitted light from the light-emitting diode 91 described below is uniformly diffused and then emitted to the front optical function. In the six reflecting plates 61, five pieces (61a to 61e) in order from the top are circular disk shapes of equal size, and are arranged in a row at equal intervals so that the centers are on the same straight line. The remaining one of the reflecting plates 61f is a substantially hexagonal plate-like body that is smaller than the disk-shaped reflecting plate 61a to the reflecting plate 61e.

The connecting member 62 is an arm-shaped member that connects the six reflecting plates 61, and is connected between the reflecting plates 61 by two arm-shaped bodies. Further, as shown in detail in FIG. 9B, the connecting member 62 is connected to the rear side of each of the reflecting plates 61, and the reflecting plate 61 and the connecting member 62 have the same surface on the rear end surface. Further, when each of the reflecting plates 61a to 61f overlaps the flexible substrate 42 and the pressing member 43, the reflecting plates 61a to 61f are located directly below the detecting sensors 57a to 57f of the flexible substrate 42.

The flexible substrate 42 is a printed substrate having light transmissivity and flexibility. As shown in FIG. 10A and FIG. 10B, the flexible substrate 42 extends downward in the lower right portion, and the lower end protrudes leftward to form the terminal portion 55. A reinforcing plate 56 is attached to the front side of the terminal portion 55.

As shown in FIG. 10B, on the flexible substrate 42, six detection sensors 57 (57a to 57f) for detecting changes in electrostatic capacitance are provided as detection portions at positions corresponding to the operation menu 51 of the operation nameplate 41. . The detecting sensor 57 is formed at a position corresponding to the operation menu 51 when the nameplate 41 and the flexible substrate 42 are overlapped. That is, when the nameplate 41 and the flexible substrate 42 are overlapped, the detecting sensor 57a is located immediately below (the rear side) of the text of the "refrigerated" (51a), and the detecting sensor 57b is located at "freezing" ( Directly below the text of 51b), the detecting sensor 57c is located directly below the text of the "freezing function" (51c), and the detecting sensor 57d is located in "ice making" (51d) Directly below the text, the detection sensor 57e is located directly below the text of "Power Save" (51e), and the detection sensor 57f is located directly below the text of the "Key Lock" (51f). Further, the number of the detecting sensors 57 is not limited to six, and the necessary number is determined according to the number of operating menus.

As shown in FIG. 11, the support member 44 is a plate-shaped body which is formed of a light-shielding material and has a substantially square shape. In the support member 44, a plurality of concave portions 71 are formed at a portion directly below the rear surface (the rear side) of the transmissive portion 54 when the nameplate 41 is overlapped, and a light-emitting diode having the operation substrate 45 is formed at a bottom portion of each concave portion 71. The opening of the light-emitting diode 91 is an opening 75. The concave portion 71a to the concave portion 71e of the portion of the pressing member 43 in which the disk-shaped reflecting plate 61a to the reflecting plate 61e are disposed is formed in an inverted conical shape. The reason why the concave portion 71a to the concave portion 71e are in the shape of the inverted conical surface is such that the concave portion 71a to the concave portion 71e have a function as a reflector of the light-emitting diode 91. Further, the concave portion 71a to the concave portion 71e and the concave portion 71f of the portion of the pressing member 43 where the substantially hexagonal reflecting plate 61f is disposed are continuous by the groove 72.

The groove 72 is formed at a position directly below the coupling member 62 when the pressing member 43 is superposed. A projection 73 is formed in the groove 72. The protruding portion 73 is a portion that abuts against the end portion of the curved portion of the connecting member 62 of the pressing member 43 . In other words, when the pressing member 43 is superposed on the support member 44, only the curved end portion of the connecting member 62 abuts against the protruding portion 73, and the other portion is separated from the bottom surface of the groove 72. Further, the opening 75 for the light-emitting diode is not provided in the recess 71f. Moreover, it is also possible to provide a configuration in which only the opening 75 for the light-emitting diode is provided without providing the concave portion 71.

The notch portion 76 is a passage through which the flexible substrate 42 passes when the terminal portion 55 of the flexible substrate 42 is connected to the operation substrate 45. The restricting plate 77 is a plate for suppressing the flexible substrate 42 that enters from the slit portion 76 to the rear side of the support member 44.

As shown in FIGS. 11 and 14A, the support member 44 is provided with a first press-fitting mechanism portion 78 at both ends (upper and lower ends) in the longitudinal direction. The first press-fitting mechanism portion 78 is a mechanism that is pressed into the outer plate 31 side by the press-in bar 98 of the press-fitting member 48. The first press-fitting mechanism portion 78 is provided at the upper and lower ends of the support member 44 with an insertion hole 79 for inserting the press-in bar 98 formed in the press-fitting member 48 between the storage case 47, and a press-in piece 80 by pressing The rod 98 is inserted into the outer panel 31 side. The press-in piece 80 enters the insertion hole 79, and if the press-in rod 98 enters the insertion hole 79, it is pressed into the outer plate 31 side by pressing the rod 98, and as a result, the support member 44 is pressed together with the member on the front side thereof. It abuts against the back side of the outer panel 31.

As shown in FIG. 11 and FIG. 14B, the support member 44 has a second press-fitting mechanism portion 82 that extends laterally on one end surface in the short-side direction (the direction orthogonal to the longitudinal direction). The second press-fitting mechanism portion 82 includes three protruding members 83 that protrude to the left side. The protruding member 83 includes a frame 84 having a substantially U-shaped front view and a press-fitting piece 85 that is located inside the frame 84 and protrudes rearward. The second press-fitting mechanism portion 82 inserts the press-fitting member 48 from the side of the support member 44 to press the support member 44 to the side, and the press-fitting piece 85 of the projecting member 83 covers the step 87 of the storage box 47, This mechanism for biasing the side of the outer panel 31.

As shown in FIG. 7, the operation substrate 45 is in contact with the light-emitting diode of the support member 44. A plurality of light-emitting diodes 91 are provided at positions corresponding to the body opening 75. A terminal support portion 93 for connecting the terminal portion 55 of the flexible substrate 42 is provided in the vicinity of the lower right corner portion of the operation substrate 45. As shown in FIG. 14B, the operation substrate 45 is held by the support member 44 at the rear of the support member 44.

As shown in Fig. 15, the storage box 47 is provided with a side opening portion 49 on the right side, and is also open at the front. In the vicinity of the left end of the storage box 47, a step 87 is formed toward the front. An edge portion 86 is provided at a front end portion of the storage box 47. The edge portion 86 is pressed and fixed to the back surface of the outer panel 31 so that the right end side of the storage box 47 coincides with the right end side of the outer panel 31 of the first door 21 of the refrigerating compartment.

The press-in member 48 includes: a side panel 97; a press-in bar 98 extending perpendicularly from the side of the longitudinal direction of the side panel 97 with respect to the side panel 97; and a plurality of locking pieces 99 with respect to the side panel 97 It is formed vertically. The press-fitting member 48 is inserted into the storage box 47 from the side opening portion 49 of the storage box 47, and is fixed to the storage box by the locking piece 99 in a state where the support member 44 housed in the storage box 47 is pressed into the front (outer plate 31). 47.

The touch panel unit 40 is a laminated body in which the nameplate 41, the flexible substrate 42, the pressing member 43, the support member 44, and the operation substrate 45 are sequentially laminated from the front. In the laminated body, the operation menu 51 of the nameplate 41, the detection sensor 57 of the flexible substrate 42, the pressing member 43, and the concave portion 71a to the concave portion 71f of the support member 44 are overlapped. The pressing member 43 is overlapped with the supporting member 44 in a state where the connecting member 62 abuts on the protruding portion 73 formed in the groove 72 of the supporting member 44. In other words, the pressing member 43 and the supporting member 44 are in contact only with the protruding portion 73 and the connecting member 62, and the other portions are in a state in which a small gap is provided.

The terminal portion 55 of the flexible substrate 42 is connected to the operation substrate 45 at the rear from the notch portion 76 via the inclined portion 76a of the support member 44, and is connected to the terminal support portion 93. In the state in which the terminal portion 55 is connected to the terminal support portion 93, the flexible substrate 42 is restricted in operation by the regulating plate 77 of the support member 44.

The laminated body is housed in the storage box 47. In the storage box 47, the edge portion 86 is temporarily fixed to the outer panel 31 by a double-sided adhesive tape or the like, and is pressed against the outer panel 31 side by the volume expansion force when the heat insulating material 33 is foamed. When the press-fitting member 48 is inserted into the opening portion (side surface) of the storage box 47, the press-in rod 98 enters the insertion hole 79 of the support member 44, and the press-fitting sheet 80 is pressed forward (see FIG. 14A). Since the press-fitting member 48 is press-fitted from the side of the storage box 47, the laminated body is press-fitted to the side, and the protruding member 83 of the support member 44 covers the step 87 of the storage box 47, thereby moving forward (refer to FIG. 14B). ). As a result, the laminated body is pressed against the back side of the outer panel 31. Therefore, the operation nameplate 41 and the flexible substrate 42 are in close contact with each other on the back surface of the outer panel 31 without a gap. Therefore, in the touch panel of the embodiment, the touch sensor 57 on the flexible substrate 42 can be used to positively detect the touch operation from the front of the outer panel 31.

In the touch panel unit 40 having such a configuration, the flexible substrate 42 can be pressed against the outer panel 31 by the pressing member 43, so that the touch operation of the user's outer panel 31 can be reliably detected. . Thereby, a refrigerator which is user-friendly and user-friendly can be realized.

Since the support member 44 includes the recessed portion 71a to the recessed portion 71e, the recessed portion 71a to the recessed portion 71e can function as a reflector to surely illuminate the operation menu 51 of the operation nameplate 41.

The flexible substrate 42 is formed of a light-transmitting material, so that it can be transparent. Light from the light-emitting diode 91 is emitted to illuminate the light transmitting portion 54 of the operation nameplate 41. Therefore, the user can clearly read the character of the operation nameplate 41 from the front of the outer panel 31.

The pressing member 43 is provided with a plurality of reflecting plates 61, and each of the reflecting plates 61 is continuously formed by the connecting member 62, whereby the plurality of detecting sensors 57 can be reliably pressed against the outer panel 31. Moreover, since the connecting member 62 has elasticity, even when the outer panel 31 is bent due to a temperature change or a pressing force during operation, the detecting sensor 57 can be surely pressed against the outer panel 31, and can always be Maintain the detection accuracy of the touch operation.

The conventional refrigerator has a problem that if the detecting sensor is disposed along the longitudinal direction of the outer panel, the detection accuracy is lowered because the outer panel is easily bent, but in the refrigerator of the embodiment, the pressing member is provided. 43. Therefore, even if the detecting sensor 57 is disposed along the longitudinal direction of the outer panel 31, the detection accuracy can be kept high.

The pressing member 43 and the supporting member 44 abut only a part (the protruding portion 73), and the other portions are separated. Therefore, even when the outer panel 31 is bent inward due to a temperature change or a pressing force at the time of operation, separation can be utilized. Partial absorption and bending can prevent the touch panel from being damaged.

The surface of the flexible substrate 42 in which the detecting sensor 57 is present is located in front of the supporting member 44, the connecting portion of the flexible substrate 42 and the operating substrate 45 is located behind the supporting member 44, and the flexible substrate 42 is in close contact with the supporting member. 44. Thereby, when the touch panel device 40 is attached to the first door 21 of the refrigerating compartment, the flexible substrate 42 is not damaged or the mounting is hindered, and the slide storage can be easily performed from the side of the door.

Since the flexible substrate 42 has no folded portion, there is no case where the flexible substrate 42 protrudes from the touch panel device 40 or partially expands, and the touch panel device is used. When the first door 21 is attached to the refrigerator compartment 40, the flexible substrate 42 is not damaged or the mounting is hindered.

The connecting portion of the flexible substrate 42 and the operation substrate 45 in the support member 44 and the portion adjacent to the connection portion are formed with the inclined portion 76a or the cutout portion 76, so that the terminal portion 55 of the flexible substrate 42 is induced to the rear to prevent the flexibility. The substrate 42 floats from the support member 44. Moreover, by arranging the limiting plate 77, it is possible to surely prevent the flexible substrate 42 from floating from the support member 44. Further, since the regulating plate 77 is fixed to the support member 44 in a state where the flexible substrate 42 is pressed from the front, the connection portion between the flexible substrate 42 and the operation substrate 45 can be prevented from being displaced.

The touch panel device 40 is disposed such that the side end of the first door 21 of the refrigerating compartment is flush with the opening 49 of the storage box 47, and the flexible substrate 42 and the operation substrate 45 are disposed in the vicinity of the opening 49. Since the connecting portion is removed, maintenance can be easily performed only by removing the side panel of the first door 21 of the refrigerating compartment.

The embodiments of the present invention have been described above, but the embodiments are presented as examples and are not intended to limit the scope of the invention. The present invention may be embodied in a variety of other forms, and various omissions, substitutions and changes may be made without departing from the scope of the invention.
