Hereinafter, an embodiment will be described with reference to Figs. 1 to 6 .

As shown in Fig. 1, in the refrigerator 1 of the embodiment, in the inside of the main body 2, the refrigerating compartment 3 and the vegetable compartment 4, which are the refrigerating temperature sections of the storage compartment for storing the foodstuffs, and the ice making in the freezing temperature section are sequentially arranged from above. The chamber 5, the upper freezing compartment 6, and the lower freezing compartment 7. The vegetable compartment 4 and the ice making compartment 5 are separated by an insulating partition wall. The refrigerator compartment 3 is opened and closed by two doors of the left door 3a and the right door 3b which are provided side by side. That is, the refrigerator of this embodiment is a so-called French door type refrigerator. The vegetable compartment 4, the ice making compartment 5, the upper freezing compartment 6 and the lower freezing compartment 7 are opened and closed by the drawer type door 4a, the door 5a, the door 6a and the door 7a, respectively. Further, the configuration of the refrigerator 1 shown in FIG. 1 is an example, and a configuration in which the number or arrangement order of the storage chambers are different or a chilled chamber or a changeable set temperature may be adopted instead of the upper freezing compartment 6. The structure of the room, etc.

The left door 3a and the right door 3b of the refrigerating compartment 3 are opened by the door opening devices 8a, 8b, respectively. Specifically, in the left door 3a, a touch sensor 9a for actuating the door opening device 8a is provided, and the user touches the detection area of the touch sensor 9a, that is, the user touches the surface of the decorative board. The position of the front touch sensor 9a is substantially forward, so that the door opening device 8a is actuated to open the left door 3a in the locked state.

In the right door 3b, a touch sensor 9b for actuating the door opening device 8b is provided. When the user touches the detection area, the door opening device 8b is actuated to open the right door 3b in the locked state. Further, on the right door 3b, an operation panel 10 for setting the refrigerator 1 or the like is provided. The operation panel 10 is composed of an electrostatic touch sensor, and the LED is always turned off. On the one hand, when the user stands in front of the refrigerator 1, it is detected by a human sensor or a proximity sensor (not shown). When you get to the person, the LED lights up. Thereby, the operation portion of the operation panel 10 is displayed so that the user can operate.

The door opening devices 8a and 8b of the present embodiment employ a solenoid type device. Hereinafter, in the case where the door opening devices 8a and 8b are collectively described, the door opening device 8 will be simply referred to, and when the touch sensors 9a and 9b are collectively described, the touch sensor 9 will be simply referred to. The touch sensor 9 is equivalent to an operation member.

Since the door opening device 8 has a conventionally used structure, detailed description thereof will be omitted. However, the door opening device 8 is located on the opposite side of the hinge (not shown) that is the center of rotation of the door, that is, in the present embodiment, it is located at the left and right sides of the refrigerator 1. Provided on the open end side of the direction center side, when the user touches the detection area of any of the touch sensors 9, the solenoid is driven to place a part of the gasket disposed in the door body or the door The front is pushed out so that the corresponding door is open.

The touch sensor 9 is disposed at a lower portion of the open end side of each door so as to be easily accessible to the user when the door is opened. As shown in FIG. 2(a), the touch sensor 9 includes a sensor substrate 12 provided on the back surface of the decorative panel 11, and the decorative panel 11 covers the front surface of the door. 2(a) schematically shows the structure of the touch sensor 9b provided in the right door 3b. The sensor substrate 12 is held by a substrate holder 13 . Further, a film-shaped operation name plate 14 is disposed between the decorative panel 11 and the sensor substrate 12, and an LED is disposed on the back side of the sensor substrate 12, that is, on the opposite side of the decorative panel 11. Substrate 15.

In the case of the present embodiment, the sensor substrate 12, the substrate holder 13, the operation indicator plate 14, and the LED substrate 15 are assembled to each other and housed in a housing formed inside the door. Inside. The storage space in which the assembled structure is housed is closed by a cap 16 and a lid member 17. At this time, the pressing portion 17a provided in the lid member 17 is pressed from the inner peripheral surface 18 of the storage space toward the decorative panel 11 side. Therefore, the sensor substrate 12 is in a state of being in close contact with the back surface of the decorative panel 11 in a state in which the operation indicator panel 14 is interposed. Further, a heat insulating member such as a urethane material 19 is filled in a portion other than the storage space inside the door.

The decorative panel 11 is attached to the door by a double-sided tape 20. Further, in the present embodiment, the structure located in the vicinity of the touch sensor 9 is firmly adhered to the cover 16 in the present embodiment. In other words, a holding portion for holding the decorative panel 11 on the door is also provided in the vicinity of the touch sensor 9. The double-sided tape 20 corresponds to a holding member and an adhesive member. Specifically, as shown in FIG. 2( b ), the decorative panel 11 is fixed by the double-sided tape 20 in the longitudinal direction of the door (the vertical direction in the drawing) over the length of the sensor substrate 12 . Thereby, the decorative panel 11 can be restricted from moving toward the front side (upper side in the drawing) due to deformation or the like, that is, the distance between the decorative panel 11 and the sensor substrate 12 can be suppressed from changing. In addition, in FIG. 2(b), for example, a double-sided tape 20 may be provided under the sensor substrate 12 in the lateral direction of the door (the horizontal direction in the drawing) to hold the decorative panel 11. Moreover, a structure may be adopted in which the double-sided tape 20 is attached in parallel only in the vicinity of the touch sensor 9, whereby the position farther from the touch sensor 9 is in the vicinity of the touch sensor 9. The decorative panel 11 is fixed more strongly. Further, a structure may be employed in which, in addition to the double-sided tape 20, an adhesive is used in the vicinity of the touch sensor 9, whereby the decorative panel 11 is more strongly fixed.

As shown in FIG. 3, the sensor substrate 12 is provided with a detection area R for detecting a user's operation, that is, a user's access to the surface of the decorative panel 11, by a change in electrostatic capacitance, and A plurality of substrate openings 21 are formed in a state of being separated from each other along the detection region R. In the sensor substrate 12, although not shown, a circuit component or the like is mounted on the back side, that is, on the surface opposite to the surface side facing the decorative panel 11.

The substrate opening portion 21 is for transmitting the light irradiated from the LED 29 (see FIG. 5) to the side of the operation panel 14 which is the side of the operation panel 11, and the LED 29 is provided on the LED substrate disposed on the back side of the sensor substrate 12. 15 on. Therefore, the substrate opening portion 21 is formed to be larger than the size of the LED 29 in consideration of the processing accuracy at the time of mounting the LED 29, the dimensional accuracy of the substrate, the assembly accuracy, and the like.

On the other hand, each of the substrate opening portions 21 is formed to have a minimum size. In addition, the minimum necessary size refers to the degree of irradiation to the opening portion 28 of the indicator plate formed on the operation indicator plate 14 as described later with reference to FIG. 6 in consideration of the mechanical precision or the like. size. Therefore, the substrate opening portion 21 of the present embodiment is formed in a vertically long elliptical shape. By providing the substrate opening portion 21 having such a size, the change in electrostatic capacitance can be detected more accurately.

That is, in order to accurately detect the user's operation, it is necessary to closely contact the sensor substrate 12 at a certain distance to closely contact the back side of the decorative panel 11. At this time, the decorative panel 11 is held by the double-sided tape 20 so that the distance from the sensor substrate 12 is fixed as described above. However, if the substrate opening portion 21 is excessively enlarged, for example, if it is formed in a slit shape over the entire circumference of the detection region R, the detection region R and other portions of the sensor substrate 12 (hereinafter, for convenience) The body portion is referred to as a state of being only slightly connected. As a result, it is possible that the detection region R is swelled from the body portion of the sensor substrate 12.

On the other hand, when each of the substrate opening portions 21 is formed to a minimum size, the connection portion between the detection region R and the main body portion is made firm, and the detection region R can be prevented from bulging or the like. At this time, as described above, the circuit component is mounted on the back side of the sensor substrate 12, and the wiring pattern 23 is provided on the surface side, so that the detection region R is flush with the body portion and is flat. Thereby, as long as the sensor substrate 12 is brought into close contact with the back side of the decorative panel 11, the detection region R is also in close contact, and the detection accuracy can be prevented from being lowered.

Further, on the sensor substrate 12, a guard electrode 22 is provided on the outer peripheral side of the detection region R. The guard electrode 22 serves to prevent the door from being accidentally opened when the user touches a relatively wide range including the periphery of the detection area R. Specifically, for example, when the user cleans the door, the user touches a wide range including the detection region R with a rag or the like.

Further, each of the substrate opening portions 21 is formed in a so-called long hole shape. At this time, after the hole as the reference is opened by the drill, the sensor substrate 12 is directly moved in a predetermined direction, whereby the substrate opening portion 21 can be formed, and the hole processing can be easily performed.

Further, the sensor substrate 12 shown in FIG. 3 is provided to the right door 3b. In the present embodiment, in the case of the touch sensor 9a provided in the left door 3a, the positional relationship of the detection region R is as shown in FIG. 1, and is formed in the sensor substrate 12 for the right door 3b shown in FIG. symmetry. That is, in the present embodiment, the sensor substrates 12 arranged differently are used in the left door 3a and the right door 3b. More specifically, for the sensor substrate 12 provided in the left door 3a and the right door 3b, the detection region R is located on the open end side.

In this case, in consideration of the general viewpoint of reducing the number of components to reduce the cost, it is preferable to use the common sensor substrate 12, but if the common sensor substrate 12 is used, the detection region R is used. The location will be different in each door. More specifically, the distance from the open end of each door to the detection area R will be different in the left door 3a and the right door 3b. At this time, the user may feel uncoordinated for the operation, or lose the left-right symmetry, resulting in a decline in design.

Therefore, in the present embodiment, the two kinds of sensor substrates 12 for the left door 3a and the right door 3b are used in consideration of the operability of the user. Thereby, in the left and right doors, the distance from the open end side to the detection area R is uniform, and it is not uncomfortable.

Further, in the present embodiment, the sensor substrate 12 is not simply rectangular, but is provided with a cut-in portion 12b which is located above the lower side 12a below the detection region R. Further, the cut-in portion 12b is provided with connectors for outputting the sensor signals and connectors 24 and 25 for connection to the LED board 15. That is, the connectors 24 and 25 are provided below the circuit component or the like of the sensor substrate 12. Thereby, for example, even when water falls on the cables 26 and 27, the water droplets can be prevented from falling onto the circuit parts or the like of the sensor substrate 12. In addition, the connectors 24, 25 are mounted on the back side of the sensor substrate 12.

Further, by providing the cut-in portion 12b, the lower end of the sensor substrate 12 becomes the lower side 12a below the detection region R, and the sensor substrate 12 can be made as close as possible to the lower side of the door. Further, in the case of the refrigerator 1 having a plurality of storage rooms as in the present embodiment, when the user does not have to open the door device 8 and the user has to open the door by hand, the lower portion of the door is often grasped by hand to open. Therefore, it can be considered that the user can easily operate the touch sensor 9 by providing the cut-in 12b and arranging the detection region R near the lower end of the door.

Further, the vertically long decorative panel 11 may have a structure in which the central portion of the up-and-down direction is deformed in a protruding manner, but the touch sensor 9 is disposed on the lower side of the decorative panel 11, Even if deformation occurs, the amount of deformation can be expected to be smaller than that of the central portion, and it is possible to further provide a structure having resistance to erroneous detection or the like.

Further, in the case of operating the touch sensor 9, if the position of the detection area R is not known, it is difficult to perform the operation. Therefore, in the present embodiment, a presentation member that visually presents the detection region R is provided. The presentation member is composed of an operation indicator plate 14 and an LED substrate 15.

Further, a configuration is adopted in which a proximity sensor (not shown) is provided on the sensor substrate 12 to cause the LED 29 to be constantly extinguished, and when a proximity sensor detects that a person wants to operate, the LED is caused. 29 lights up or flashes.

The operation indicator plate 14 is formed of a resin material or the like into a film shape, and as shown in FIG. 4, is substantially the same size as the outer shape of the sensor substrate 12. On the operation indicator plate 14, a plurality of indicator plate openings 28 are formed. In the case of the present embodiment, the indicator plate opening portion 28 is an opening having two rows of circular hole shapes along the left and right sides (see FIG. 3) of the detection region R.

As shown in FIG. 5, the LED board 15 is provided with a plurality of LEDs 29 in one-to-one relationship with the board opening 21 at a position corresponding to the board opening 21 of the sensor board 12. The LED board 15 is connected to the sensor substrate 12 by a cable 26 via a connector 30.

Further, the door is opened and closed to the refrigerating compartment 3, and of course, heat insulation is required. Therefore, as described above, the inside of the door is filled with the urethane material 19 or the like. At this time, when the sensor substrate 12 is placed inside the door, since the urethane material 19 is not filled in the storage space, the heat insulating property may change. Therefore, it is preferable that the storage space is as much as possible. For small capacity. In other words, when the sensor substrate 12, the operation indicator plate 14, and the LED substrate 15 are arranged to overlap each other as shown in FIG. 2, it is preferable to be as thin as possible.

On the other hand, when the distance from the LED board 15 becomes closer, the distance between each LED 29 and the operation indicator board 14 becomes closer. As a result, in the back side of the operation indicator panel 14, the range in which each of the LEDs 29 can be irradiated (hereinafter, referred to as an irradiation range for convenience) becomes small. Therefore, in the case where the opening portion 28 of the indicator plate of the operation panel 14 is large, more specifically, if the size of the opening portion 28 of the indicator plate is larger than the irradiation range of the LED 29, the opening portion 28 of the indicator plate cannot be uniformly illuminated. Bright, resulting in uneven brightness. Moreover, the brightness unevenness is also seen by the user, so there is a possibility that the design or taste of the refrigerator 1 is impaired.

Therefore, in the present embodiment, the size of the indicator plate opening portion 28 is formed to be smaller than the irradiation range of the LED 29 at the position where the indicator plate 14 is operated. Thereby, the detection area R is presented to the user as a range surrounded by a so-called dot display from the front side of the door. At this time, since unevenness in brightness does not occur in the opening portion 28 of the indicator plate, the light of each of the opening portions 28 of the indicator plate becomes uniform, and the grade of the refrigerator 1 is not impaired.

Further, in the present embodiment, the indicator plate opening portion 28 is provided as shown in the front view of FIG. 2(b), and is provided above the center line L1 of the LED 29 as shown in the longitudinal cross-sectional view of FIG. Further, the position of the opening portion 28 of the indicator plate naturally enters the irradiation range of the LED 29. Therefore, the brightness is maximized from the direction of the straight line L2 passing through the LED 29, the substrate opening portion 21, and the indicator plate opening portion 28. In the case of this embodiment, the direction of the straight line L2 is set to be close to the height of the eye when the ordinary adult uses the refrigerator 1.

At this time, assuming that the position of the opening portion 28 of the indicator plate is located on the front surface of the LED 29, that is, on the center line L1, it is difficult to grasp the position of the detection region R from the user who comes to the front of the refrigerator 1 in order to open the door of the refrigerator 1. .

On the other hand, when the position of the opening portion 28 of the indicator plate is positioned higher than the front surface of the LED 29 as in the present embodiment, it is easy to grasp the position of the detection region R even if the user comes to the front of the refrigerator 1.

Further, when the LED 29 of the same color as the decorative panel 11 is used, a so-called high-brightness LED may be used. Since the front surface brightness of such an LED element is the highest, if the indicator board opening part 28 is provided in the front surface of an LED, it may become dazzling. Also, considering that the refrigerator 1 is used almost every day, it is not desirable to feel so dazzling every time the door is operated. Therefore, by dislocating the position of the opening portion 28 of the indicator plate from the front surface of the LED 29 as in the present embodiment, it is possible to avoid a situation in which the person is dazzled. In particular, if the touch sensor 9 is disposed on the lower end side of the door as shown in FIG. 1, the LED 29 may be located at the line of sight of the child, but by staggering the opening portion 28 of the indicator plate from the front of the LED 29. The configuration prevents the child from looking directly at the LED 29.

According to the refrigerator 1 described above, the following effects are obtained.

The decorative panel 11 of the refrigerator 1 is disposed in the vicinity of the sensor substrate 12, and is held at a constant distance from the sensor substrate 12 by holding the holding member (double-sided tape 20) of the decorative panel 11. Thereby, the distance from the sensor substrate 12 in the vicinity of the sensor substrate 12 constituting the touch sensor 9 which is an operation member is fixed, so that the detection sensitivity deterioration when the user's door opening operation is detected can be reduced or The possibility of false detection.

As the holding member, a double-sided tape 20 as an adhesive member is used, and the adhesive member adheres the decorative sheet 11 to the structure located in the vicinity of the sensor substrate 12. Therefore, the fixing operation can be easily performed when the decorative panel 11 is fixed.

Further, the refrigerator 1 is provided with a presentation member which is constituted by the operation indicator plate 14 and the LED board 15, and presents the detection area R of the touch sensor 9 to the user, so that the user can easily grasp which part is touched to open the door. .

Further, the presentation member is composed of one or more point light sources that perform so-called dot display. Thereby, the design of the detection area R can be improved by using two lines of simple display.

The LEDs 29 that indicate the detection region R are disposed on the back side of the sensor substrate 12, and a plurality of substrate openings 21 are formed along the detection region R on the sensor substrate 12, and the plurality of substrate openings 21 are used. The light irradiated from the LED 29 is transmitted to the operation indicator board 14 side. Thereby, the possibility that the portion of the detection region R starts from the body portion of the sensor substrate 12 can be reduced, and the sensor substrate 12, that is, the detection region R can be brought into close contact with the decorative panel 11. Therefore, it is possible to prevent a decrease in detection accuracy.

The indicator board opening portion 28 of the operation indicator panel 14 is formed to be smaller than the irradiation range of the LED 29, and its position is located above the LED in the longitudinal direction of the refrigerator 1. Thereby, the light from the LED 29 is irradiated toward the line of sight of the user who is close to the refrigerator 1, that is, the user who wants to open the door of the refrigerator 1. Therefore, the user can easily grasp the detection area R. (Other embodiments)

For example, a configuration may be adopted in which another indicator plate opening portion 28 is provided below the indicator plate opening portion 28 of the straight line L2 shown in FIG. 6, so that a user different from the virtual height is also easily seen. In other words, the indicator plate opening portion 28 may be any shape or arrangement as long as it can visually present the detection region R to the user.

Further, the indicator plate opening portion 28 may not be in two rows as exemplified in the embodiment, but may be different in number, and the indicator plate opening portion 28 may be provided in the center portion of the detection region R or Multiple.

In one embodiment, a case where a person is detected by a human sensor or a proximity sensor or the like to illuminate an LED is exemplified, but a normal lighting mode in which the user always lights the LED may be provided.

In one embodiment, the case where the holding member is provided regardless of the distance from the hinge which is the center of rotation is exemplified, but the distance from the hinge to the end of the door 3a, 3b opposite to the hinge may be used. The holding member is provided on the longer door, or the fixing by the holding member is made stronger.

As a result, the door having a stronger impact force applied when the doors 3a and 3b are closed is more strongly fixed, so that the doors 3a and 3b can be fixed by an optimum force.

In one embodiment, the case where the holding member is provided in the vicinity of the touch sensor 9 is exemplified, but the holding member may be provided in the vicinity of the position where the door opening device 8 is pushed forward. Thereby, even when an impact force is applied from the door opening device 8 when the doors 3a and 3b are opened, the decorative panel 11 can be prevented from bulging from the doors 3a and 3b, and the decorative panel 11 can be prevented from falling off from the doors 3a and 3b.
