[0099] By making the height of the first touch detection device (101) and the height of the second touch detection device (102) different, it is possible to prevent the second touch detection device (102) from being unintentionally touched when the first touch detection device (101) is touched. Likewise, it is possible to prevent the first touch detection device (101) from being unintentionally touched when the second touch detection device (102) is touched. Through this, malfunction of the door opening device (40) can be prevented.
[0100] FIG. 5 illustrates a refrigerator according to one embodiment in which a touch sensing device is separated from the door. FIG. 6 illustrates a refrigerator according to one embodiment in which the touch sensing device is disassembled. FIG. 7 illustrates a refrigerator according to one embodiment in which a holder and a light guide member are separated. FIG. 8 illustrates FIG. 7 from a different angle. FIG. 9 illustrates a cross-section along B-B' of FIG. 4. FIG. 10 illustrates a cross-section along C-C' of FIG. 5.
[0101] Hereinafter, the structure of a touch detection device (100) according to one embodiment is described with reference to FIGS. 5 to 8. Since the first touch detection device (101) and the second touch detection device (102) have substantially the same configuration, only the second touch detection device (102) will be described. Also, the second touch detection device (102) will be referred to as the touch detection device (100). Additionally, only the second door (32) will be described below, but the following description can be equally applied to the first door (31).
[0102] Referring to FIGS. 5 to 8, the touch sensing device (100) may include a cover (110) forming the exterior of the touch sensing device (100), a light guide member (130) disposed inside the cover (110) and including an indicator (131), a holder (120) arranged to cover at least a portion of the light guide member (130) inside the cover (110), a printed circuit board (140), at least one light source (150) configured to emit light, and a touch sensor (160).
[0103] The cover (110) can form the exterior of the touch sensing device (100) that is exposed to the outside of the second door (32) together with the indicator (131). At least a portion of the cover (110) may protrude from the side (32a) of the second door (32).
[0104] The remaining part of the touch detection device (100), excluding the part of the cover (110) protruding from the side (32a) of the second door (32) and the indicator (131), may be positioned on the inside of the second door (32). To accommodate the touch detection device (100), a door receiving portion (32c) may be provided on the side (32a) of the second door (32). The door receiving portion (32c) may be formed by recessing a part of the side (32a) of the second door (32) inward. At least one door groove (32d) may be formed in the door receiving portion (32c) to allow the cover projection (114) of the touch detection device (100) to be inserted.
[0105] As described above, the touch detection device (100) may be positioned in front of the second handle (32b). Accordingly, the door receiving portion (32c) for receiving the touch detection device (100) may be located in front of the second handle (32b) on the side (32a) of the second door (32).
[0106] A portion of the cover (110) may be positioned to face the front of the refrigerator (1). Hereinafter, the portion of the cover (110) positioned to face the front (+X direction) of the refrigerator (1) is referred to as the front surface (111) of the cover (110). A cover hole (112) into which an indicator (131) is inserted may be formed on the front surface (111) of the cover (110). The indicator (131) may be exposed to the outside of the cover (110) through the cover hole (112).
[0107] According to one embodiment, the indicator (131) may protrude forward from the front (111) of the cover (110) through the cover hole (112). When the front of the indicator (131) protrudes forward beyond the front (111) of the cover (110), the four sides surrounding the front of the indicator (131) may also be exposed to the outside of the cover (110). Accordingly, light emitted to the outside of the cover (110) through the indicator (131) may be emitted through the front of the indicator (131) and the four sides surrounding it.
[0108] According to one embodiment, the indicator (131) is inserted into the cover hole (112), and the front surface of the indicator (131) may be located on the same surface as the front surface (111) of the cover (110).
[0109] According to one embodiment, the indicator (131) is inserted into the cover hole (112), and the front of the indicator (131) may be positioned behind the front (111) of the cover (110). In other words, the indicator (131) may be positioned behind the front (111) of the cover (110) while inserted into the cover hole (112).
[0110] In this specification, the term "indicator" may refer to a part of a touch sensing device that notifies a user of a touch location. For example, an indicator may refer to a part that emits light to enable the recognition of a touch location. An indicator may be referred to by various terms such as a light-emitting part, an identification part, a display part, etc.
[0111] An indicator (131) exposed to the outside of the cover (110) can receive light emitted from at least one light source (150) and emit it to the outside of the cover (110). The light emitted from at least one light source (150) can be emitted to the outside of the touch detection device (100) through the indicator (131). Accordingly, when the refrigerator (1) is located in a dark place or the light is not turned on at night, the user can easily identify the indicator (131) and easily confirm the location of the touch detection device (100) from it.
[0112] The size and shape of the cover hole (112) formed on the front surface (111) of the cover (110) may be provided to correspond to the size and shape of the indicator (131). The width and length of the cover hole (112) may be provided to be substantially the same as the width and length of the indicator (131). However, since the indicator (131) must be inserted into the cover hole (112), the width and length of the cover hole (112) may be slightly larger than the width and length of the indicator (131). For example, as shown in FIG. 5, the cover hole (112) and the indicator (131) may be provided with corresponding shapes and may be straight shapes with a narrow width and a long length in the vertical direction. The shapes of the cover hole (112) and the indicator (131) are not limited thereto. For example, the cover hole (112) and the indicator (131) can be provided in various shapes such as an arc shape, a circle shape, a square shape, an S shape, a zigzag shape, a hidden line, etc.
[0113] The touch detection device (100) may include a light-guiding member (130, FIG. 7) that is disposed on the inner side of the cover (110) and includes an indicator (131). A part of the light-guiding member (130) may be the indicator (131) described above. Since a part of the light-guiding member (130) is the indicator (131), the light-guiding member (130) may include the indicator (131).
[0114] An indicator (131), which is a part of the light-guiding member (130), may be exposed to the outside of the cover (110). The remaining part of the light-guiding member (130), excluding the indicator (131), may be placed inside the cover (110). The indicator (131) may point to a part of the light-guiding member (130) that is exposed to the outside of the cover (110) through the cover hole (112). Since the remaining part of the light-guiding member (130), excluding the indicator (131), is covered by the cover (110), it may not be exposed to the outside of the cover (110) and the second door (32).
[0115] According to one embodiment, the cover (110) may include a coupling hole (113) into which a coupling projection (122) of the holder (120) is inserted. The cover (110) may include at least one cover projection (114) into which at least one door groove (32d) formed in the door receiving portion (32c) is inserted.
[0116] Referring to FIGS. 6 through 8, the light guide member (130) may include a first part (132) arranged to face a first surface (141) of a printed circuit board (140) and configured to allow light from at least one light source (150) to be incident thereon, and a second part (133) extending from the first part (132) and reflecting the light reflected through the first part (132) to an indicator (131). The first part (132) may extend along a second direction (Y direction). The first part (132) may be arranged at a predetermined distance from the first surface (141) of the printed circuit board (140) in a first direction. The second part (133) may extend along a first direction (X direction) from one end of the first part (132). The second part (133) can be extended from the end of the first part (132) in the second direction toward the inner surface of the cover hole (112).
[0117] The second part (133) of the light guide member (130) may include an indicator (131). An indicator (131) may be provided at the front end (the end in the +X direction) of the second part (133). The second part (133) may include a first extension part (133a) and a second extension part (133b) that are spaced apart from each other. The first extension part (133a) and the second extension part (133b) may be spaced apart in the second direction (Y direction). A groove (133c) may be formed between the first extension part (133a) and the second extension part (133b) that are spaced apart from each other. A conductive member (170) may be disposed in the groove (133c) formed between the first extension part (133a) and the second extension part (133b).
[0118] The light guide member (130) may include an injection part (134). The injection part (134) may be provided to be inserted into an injection hole (121) of a holder (120) to be described later. According to one embodiment, the injection part (134) may include a first injection part (134a) and a second injection part (134b) arranged spaced apart from each other. The injection part (134) will be described later.
[0119] The light guide member (130) can be formed integrally by injection molding. The first part (132), the second part (133), the indicator (131), and the injection part (134) of the light guide member (130) can be formed integrally by injection molding.
[0120] A touch detection sensor (100) may include at least one light source (150), a touch sensor (160), a printed circuit board (140) configured to mount at least one light source (150) and the touch sensor (160), and a holder (120) configured to support the printed circuit board (140).
[0121] At least one light source (150) may be configured to emit light. For example, at least one light source (150) may be a light-emitting diode (LED). The light-emitting diode may be configured to emit light of a wavelength corresponding to at least one color among red, green, blue, or white.
[0122] According to one embodiment, at least one light source (150) may include a first light source (151), a second light source (152), a third light source (153), and a fourth light source (154) mounted spaced apart from each other on a printed circuit board (140). The first light source (151), the second light source (152), the third light source (153), and the fourth light source (154) may be arranged spaced apart from each other along the direction (Z direction) in which the indicator (131) extends. However, this is not limited thereto. The number and arrangement of the light sources (150) may be changed.
[0123] According to one embodiment, at least one light source (150) may be mounted on the first surface (141) of the printed circuit board (140). A touch sensor (160) may be mounted on the second surface (142) of the printed circuit board (140). The first surface (141) of the printed circuit board (140) may be positioned to face the front (+X direction) of the refrigerator (1). The second surface (142) of the printed circuit board (140) may be positioned to face the rear (-X direction) of the refrigerator (1).
[0124] The touch sensor (160) may be a touch sensor that operates in a capacitive manner. The touch sensor (160) mounted on the second surface (142) of the printed circuit board (140) may be electrically connected to a terminal provided on the first surface (141) of the printed circuit board (140) through a via formed in the printed circuit board (140). The transparent electrode (172) of the conductive member (170) to be described later may be electrically connected to a terminal provided on the first surface (141) of the printed circuit board (140). Accordingly, the touch sensor (160) may be electrically connected to the transparent electrode (172).
[0125] The thickness of the touch sensor (160) may be thicker than the thickness of at least one light source (150). The thickness of the touch sensor (160) and at least one light source (150) may refer to the length in the first direction (X direction). When the touch sensor (160) is mounted on the first surface (141) of the printed circuit board (140) on which at least one light source (150) is placed, the first part (132) of the light guide member (130) and the touch sensor (160) may interfere with each other. To avoid interference between the first part (132) and the touch sensor (160), if the distance in the first direction between at least one light source (150) and the first part (132) of the light guide member (130) is increased, the distance between the indicator (131) and at least one light source (150) is increased, so that the intensity of the light emitted through the indicator (131) can be lowered and the brightness of the indicator (131) can be reduced.
[0126] According to one embodiment, the touch sensor (160) is mounted on the second surface (142) of the printed circuit board (140), so that interference between the first part (132) of the light guide member (130) and the touch sensor (160) can be avoided. Therefore, a decrease in brightness of the indicator (131) can be prevented.
[0127] The light guide member (130) may be made of a material that reflects light incident from at least one light source (150) into the interior of the light guide member (130). Light incident on the light guide member (130) may be transmitted to an indicator (131) as it is reflected within the interior of the light guide member (130). The light guide member (130) may have a refractive index greater than that of an external environment such as air. The light guide member (130) may be formed from a translucent resin. The light guide member (130) may be molded by injection molding the translucent resin. For example, the light guide member (130) may be made of a material such as polymethyl methacrylate (PMMA) and polycarbonate (PC), which have high light transmittance and strong durability. For example, the light guide member (130) can be formed from a resin having diffusion characteristics of 50% light transmittance.
[0128] Referring to FIGS. 6 to 8, the holder (120) can support a printed circuit board (140). The holder (120) may include a plurality of support protrusions (123) provided to support a second surface (142) of the printed circuit board (140). Each of the plurality of support protrusions (123) may be provided to support a part of the side of the printed circuit board (140) and a part of the second surface (142) adjacent to the side. The plurality of support protrusions (123) are spaced apart along the edge of the printed circuit board (140) so as to stably support the printed circuit board (140).
[0129] The holder (120) can be coupled to the cover (110). As described above, the cover (110) may include a coupling hole (113), and the holder (120) may include a coupling projection (122) provided to be inserted into the coupling hole (113). The holder (120) can be coupled to the cover (110) by inserting the coupling projection (122) of the holder (120) into the coupling hole (113) of the cover (110).
[0130] A holder (120) may be provided to cover at least a portion of a light-guiding member (130). The holder (120) can prevent light that has passed through the light-guiding member (130) without being reflected inside the light-guiding member (130) from leaking into the gap between the cover (110) and the door (30). Specifically, the holder (120) may cover the front of a first portion (132) of the light-guiding member (130) and one side of at least a portion of a second portion (133). At least a portion of the second portion (133) may point to a first extension (133a).
[0131] Referring to FIG. 9, the reason the holder (120) covers one side of the first extension (133a) and does not cover the second extension (133b) is that the cover (110) covers the second extension (133b). Since the cover (110) is formed of a material that cannot transmit light, even if light is transmitted through the second extension (133b) covered by the cover (110), it may not leak out of the cover (110).
[0132] As illustrated in FIG. 9, the front of the first part (132) and the side of the first extension (133a) may not be covered by the cover (110). In this case, light passing through the first part (132) or the first extension (133a) may proceed toward the inside of the door (30). If the door (30) is formed of a material through which light can pass, the light that has proceeded toward the inside of the door (30) may be visible from the outside of the door (30). Even if the door (30) is formed of a material through which light cannot pass, there may be a gap between the cover (110) and the side (32a) of the door (30) due to assembly tolerances, and light may leak through this gap. In other words, light leakage may occur. Hereinafter, light leakage and light leakage may be used interchangeably.
[0133] The holder (120) can prevent light transmitted through the light guide member (130) from leaking toward the door (30) by covering at least a portion of the light guide member (130). If light leaks through the gap between the cover (110) and the door (30), the indicator (131) identification effect in dark places may be reduced, and the aesthetic appeal and quality of the refrigerator (1) may be lowered.
[0134] The holder (120) may be formed of opaque resin so that light passing through the light guide member (130) does not pass through the holder (120). If light passing through the light guide member (130) also passes through the holder (120), the light leakage phenomenon described above may occur. To prevent light leakage or light leakage through the gap between the cover (110) and the door (30), the holder (120) may be formed of opaque resin.
[0135] The holder (120) may be formed in a white color to reflect light incident on the inner surface of the holder (120) toward the light guide member (130). If the holder (120) absorbs most of the light incident on the inner surface of the holder (120), the light transmission efficiency to the indicator (131) may decrease. If the light transmission efficiency to the indicator (131) decreases, the brightness of the indicator (131) may decrease. To prevent a decrease in the brightness of the indicator (131), the holder (120) may be formed to have a white color.
[0136] The holder (120) may be formed of a white-colored opaque resin to prevent light leakage and a decrease in brightness of the indicator (131). The holder (120) may be molded by injection molding a white-colored opaque resin.
[0137] According to the present disclosure, the holder (120) and the light guide member (130) can be formed integrally. More specifically, the holder (120) and the light guide member (130) can be formed integrally by double injection molding. For example, the holder (120) and the light guide member (130) can be formed integrally by first injection molding the holder (120) and second injection molding the light guide member (130).
[0138] The holder (120) may include an injection hole (121) so that the light guide member (130) can be injected secondarily after the holder (120) is injected firstly. The holder (120) may be molded by injecting a white-colored opaque resin firstly. The light guide member (130) may be molded by injecting a translucent resin secondarily through the injection hole (121) after the holder (120) is molded. Since the holder (120) and the light guide member (130) are formed integrally by double injection, the holder (120) and the light guide member (130), which have different materials, can be formed integrally without separate assembly, bonding, or joining processes.
[0139] According to one embodiment, the injection hole (121) of the holder (120) may include a first injection hole (121a) and a second injection hole (121b) for smooth injection molding of the light guide member (130). However, it is not limited thereto. The number of injection holes (121) can be changed.
[0140] At least a portion of the light guide member (130) may be exposed to the outside of the holder (120) through the injection hole (121). Specifically, the injection portion (134) of the light guide member (130) may be exposed to the outside of the holder (120) through the injection hole (121). The injection portion (134) may have a size and shape corresponding to the injection hole (121). According to one embodiment, the injection portion (134) may include a first injection portion (134a) inserted into the first injection hole (121a) and exposed to the outside of the holder (120), and a second injection portion (134b) inserted into the second injection hole (121b) and exposed to the outside of the holder (120). The injection portion (134) can be extended in a second direction (+Y direction) from the side end of the first portion (132).
[0141] Referring to FIGS. 6, 9 and 10, the touch sensing device (100) may include a conductive member (170) disposed between an indicator (131) and a printed circuit board (140).
[0142] A conductive member (170) may be provided between the inner surface (131a) of the indicator (131) and the first surface (141) of the printed circuit board (140). The inner surface (131a) of the indicator (131) may refer to one surface of the indicator (131) or a part of the light-guiding member (130) that is positioned on the inside of the cover (110) and faces the first surface (141) of the printed circuit board (140).
[0143] The conductive member (170) may be provided to transmit a user's touch input to the indicator (131) to a touch sensor (160). The conductive member (170) may serve to transmit a user's touch input to the indicator (131) to a touch sensor (160) positioned apart from the indicator (131). The conductive member (170) may fill the space between the inner surface (131a) of the indicator (131) and the first surface (141) of the printed circuit board (140). By being positioned between the inner surface (131a) of the indicator (131) and the first surface (141) of the printed circuit board (140), the conductive member (170) may support the indicator (131) and absorb shocks applied to the indicator (131).
[0144] The conductive member (170) may be provided to contact the inner surface (131a) of the indicator (131) and the first surface (141) of the printed circuit board (140). The conductive member (170) may be electrically connected to a terminal or wiring provided on the first surface (141) of the printed circuit board (140) and electrically connected to the touch sensor (160).
[0145] Referring to FIGS. 9 and 10, the conductive member (170) may include a block body (171) and a transparent electrode (172) provided to cover at least a portion of the outer surface of the block body (171). The transparent electrode (172) may include indium tin oxide (ITO). The transparent electrode (172) may have the form of a film or a thin film.
[0146] As illustrated in FIGS. 9 and 10, the transparent electrode (172) can cover the front, rear, top, and bottom surfaces of the block body (171). The front surface of the block body (171) may point to one side of the block body (171) facing the +X direction, and the rear surface of the block body (171) may point to one side of the block body (171) facing the -X direction. The top surface of the block body (171) may point to one side of the block body (171) facing the +Z direction, and the bottom surface of the block body (171) may point to one side of the block body (171) facing the -Z direction.
[0147] According to one embodiment, the transparent electrode (172) may cover all sides of the block body (171) or cover the front, rear, and both sides of the block body (171).
[0148] The block body (171) may be made of a transparent material so that light incident from at least one light source (150) to the first part (132) and / or second part (133) of the light guide member (130) can be directed toward the indicator (131) along the interior of the second part (133) of the light guide member (130) without interference with the block body (171). For example, the block body (171) may be a silicone rubber formed transparently with a certain elasticity. The block body (171) may be made of transparent glass. The block body (171) may be made of a porous foam having a porosity such that at least a portion of the light emitted from at least one light source (150) can be transmitted. The block body (171) may be composed of at least one of a porous foam, silicone rubber, and glass that allows light reflected along the interior of the light guide member (130) to pass through.
[0149] As described above, since a conductive member (170) for transmitting a user's touch on the indicator (131) to a touch sensor (160) must be disposed on the inner side of the indicator (131), it is difficult to place at least one light source (150) toward the inner surface (131a) of the indicator (131). At least one light source (150) may be placed on one side of the conductive member (170) to avoid interference with the conductive member (170). At least one light source (150) may be placed spaced apart from the indicator (131) in a first direction (X direction) and a second direction (Y direction). In such a placement, most of the light emitted from the light source (150) may be incident on the first part (132) of the light guide member (130).
[0150] The light guide member (130) can reflect light within the light guide member (130) and transmit it to the indicator (131). Light incident on the first part (132) of the light guide member (130) can be reflected from the first part (132) and the second part (133) and directed toward the indicator (131).
[0151] As described above, a conductive member (170) may be disposed in the groove (133c) of the light guide member (130). Since the conductive member (170) is formed of a material through which at least a portion of the incident light can be transmitted, light incident on the conductive member (170) from the light source (150) and at least one of the first part (132) and the second part (133) can pass through the conductive member (170) and be reflected from the second part (133). The light reflected from the second part (133) can be emitted through the indicator (131).
[0152] However, if some of the light incident on the first part (132) passes through the first part (132) toward the inside of the door (30), or if some of the light incident on the second part (133) passes through the second part (133) toward the gap between the door (30) and the cover (110), light leakage may occur in the door (30). Light leakage may degrade the aesthetic appeal and quality of the refrigerator (1). To prevent this, a holder (120) formed integrally with the light guide member (130) may cover at least a portion of the light guide member (130). The holder (120) may be formed of a material that does not transmit light. Through this, light may not leak from at least a portion of the light guide member (130) covered by the holder (120). By covering the light guide member (130) with the holder (120), unintended light leakage can be prevented, and light can be emitted only from the indicator (131). Since light is emitted only from the indicator (131), the user can more easily identify the indicator (131), and the aesthetics and completeness of the refrigerator (1) can be improved.
