Description

An embodiment of the present invention relates to a washing machine.

Conventionally, washing machines are provided with an operation display device for performing settings and displaying information related to the washing operation. For example, a configuration employing a capacitive touch panel is known for this operation display device. However, with an operation panel of a conventional configuration, if there is variation in contact sensitivity, there is a risk of problems such as erroneous recognition or inability to recognize operations. The conventional configuration has room for improvement in terms of reducing this variation in contact sensitivity.

JP 2015-083063 A

Therefore, we provide a washing machine that can reduce the variation in the touch sensitivity of the operation display device.

The washing machine of this embodiment comprises a main body, a lid for opening and closing the opening at the top of the main body, and an operation display device provided on either the main body or the lid for setting operation. The operation display device has an operation receiving member disposed on the front surface of the operation display device for receiving operations from a user, and a detection member attached to the back surface of the operation receiving member for detecting input operations from the user to the operation receiving member.

The washing machine according to one embodiment will be described below with reference to the drawings. The washing machine 1 shown in FIG. 1 is a so-called vertical axis type washing machine in which the central axis of the water tub and the rotation axis of the spin tub (not shown) are oriented in the vertical direction. The washing machine may be a horizontal axis or diagonal axis type drum washing machine. In the following description, the user side of the washing machine 1 is the front side of the washing machine 1, and the opposite side to the front side is the rear side of the washing machine 1. In this embodiment, the front-rear direction means the front-rear direction when the washing machine 1 is placed on the floor. The up-down direction of the washing machine 1 relative to the direction of gravity is the up-down direction of the washing machine 1, and the left-right direction when the washing machine 1 is viewed from the user side is the left-right direction of the washing machine 1.

The washing machine 1 comprises a main body 10, a lid 20, and an operation display device 30. As shown in FIG. 1, the main body 10 is configured as a rectangular box overall, and constitutes the outer shell of the washing machine 1. The main body 10 has an opening (not shown) on the upper side for loading and unloading laundry. The main body 10 has an outer box 11 and a top cover 12. The outer box 11 is formed into a rectangular box shape from a steel plate, for example. The outer box 11 contains a water tub and a spin tub (not shown) as a washing tub.

The top cover 12 is made of, for example, synthetic resin, and is formed, for example, in a thin rectangular ring shape with the upper surface sloping downward toward the front. The top cover 12 is not limited to being sloping downward toward the front of the washing machine 1, and may be configured to be horizontal with respect to the floor surface. The top cover 12 is provided on the upper part of the outer box 11. As shown in FIG. 1, the top cover 12 has a frame body 121, a front panel 122, and a rear panel 123. The frame body 121 is made of, for example, synthetic resin, and is formed in a rectangular frame shape that is connected in the vertical direction.

The front panel 122 is provided on the upper front side of the frame 121. As shown in FIG. 1, the front panel 122 can be configured with a power-on button 122a and a power-off button 122b. The power-on button 122a and the power-off button 122b are configured as mechanical push buttons, for example, and function as power keys.

The power-on button 122a and the power-off button 122b are electrically connected to a control device (not shown). The power-on button 122a and the power-off button 122b can be configured to be always displayed by a printing member (not shown), that is, always visible to the user. The rear panel 123 is made of, for example, synthetic resin, and is formed of a plate-shaped member. The rear panel 123 is provided on the upper rear side of the frame body 121.

As shown in Figs. 1 and 3, the lid 20 is configured, for example, in a generally rectangular plate shape. The lid 20 may be configured in a so-called bi-fold type, configured to be folded in the middle of the lid 20 in the front-rear direction. As shown in Fig. 1, the lid 20 is rotatably provided on the top of the top cover 12 and is located between the front panel 122 and the rear panel 123. The lid 20 also has a damper hinge (not shown) provided on the rear edge of the lid 20 and configured, for example, by an oil damper. The damper hinge has the function of facilitating the opening and closing operation of the lid 20. The lid 20 is rotatably connected to the top cover 12 via the damper hinge.

The lid 20 has the function of opening and closing the opening at the top of the main body 10, i.e., the opening for putting laundry in and taking it out. When the opening is closed, the lid 20 is inclined downward toward the user, i.e., toward the front. The lid 20 is not limited to being inclined downward toward the front of the washing machine 1, and may be provided so as to be horizontal to the floor surface.

As shown in Figs. 1 and 2, the lid 20 has a lid body 21, a first holding member 22, a second holding member 23, a reinforcing member 24, and a cover member 25. The lid body 21 constitutes the upper surface of the lid 20. The lid body 21 is made of, for example, a flat plate member, specifically, for example, a thin plate of hard glass with a thickness of about several mm, and may be transparent or translucent, and may be colorless or colored. The lid body 21 may also be made of synthetic resin, such as reinforced glass or acrylic glass. In addition, the corners of the peripheral portion of the lid body 21 are chamfered so that they are not sharp.

The first holding member 22 is disposed on the back side of the lid body 21. The first holding member 22 is made of, for example, synthetic resin, and is formed into a generally rectangular plate shape. As shown in FIG. 2, the first holding member 22 has a lid body mounting portion 221, a hole portion 222, and a handle portion 223. The lid body mounting portion 221 constitutes the surface of the first holding member 22, and is the surface on which the lid body 21 is placed. In this case, the lid body 21 is affixed and fixed to the lid body mounting portion 221 by double-sided tape (not shown) or the like provided between the back side of the lid body 21 and the lid body mounting portion 221.

The hole 222 is formed by penetrating the first holding member 22 in a substantially rectangular shape in the thickness direction. The hole 222 is provided in the vicinity of the substantially center of the first holding member 22. The handle portion 223 is provided at the front end of the first holding member 22. The handle portion 223 is provided, for example, across the entire width of the first holding member 22 in the left-right direction. The handle portion 223 is for a user to hang his/her fingers when opening and closing the lid 20. The handle portion 223 is provided at a position protruding forward of the lid 20 from the front end of the lid 21 when the lid 21 is placed on the lid placement portion 221. In addition, as shown in FIG. 1, the handle portion 223 is arranged at a position overlapping the front panel 122 when the lid 20 is closed. At this time, a gap is formed between the back surface of the handle portion 223 and the upper surface of the front panel 122 to the extent that the user can insert and remove his/her fingers.

As shown in FIG. 2, the second holding member 23 is disposed on the back side of the first holding member 22. The second holding member 23 is made of, for example, synthetic resin, and is formed in a generally rectangular plate shape as a whole. The second holding member 23 covers the back side of the first holding member 22 and can hold the first holding member 22. In this case, the second holding member 23 is attached to the first holding member 22 by, for example, a screw member or a snap fit.

As shown in FIG. 2, the reinforcing member 24 is formed by bending a metal plate, e.g., in a shape extending in the left-right direction. The reinforcing member 24 is attached to the rear end side of the first holding member 22, e.g., by being fixed with a screw. The reinforcing member 24 prevents the rotational force, e.g., when opening and closing the lid 20, from acting directly on the first holding member 22. The cover member 25 is made of, e.g., a synthetic resin, and is formed in a shape extending in the left-right direction. The cover member 25 is disposed on the rear side of the first holding member 22 and the second holding member 23, and can cover the outer periphery of the damper hinge (not shown). In other words, the cover member 25 prevents the smooth operation of the damper hinge from being hindered by dust, dirt, etc. adhering to the damper hinge.

The operation display device 30 has a function for setting and displaying operation. The user can set operation courses by operating the operation display device 30. Although not shown in detail, the washing machine 1 is equipped with a water supply mechanism for supplying water to the water tub. The operation display device 30 includes a control device mainly composed of a microcomputer. The control device controls the water supply mechanism based on signals from the operation unit 31 of the operation display device 30 and signals from various sensors to automatically perform washing operations such as the washing process and rinsing process, and also has a function for controlling the display unit 32 of the operation display device 30.

The operation display device 30 is composed of, for example, a capacitive touch sensor. The operation display device 30 can be provided on either the main body 10 or the lid 20. In this embodiment, the operation display device 30 is incorporated inside the lid 20. In this case, the lid body 21 functions as an operation receiving member disposed on the surface of the operation display device 30. In the description of this embodiment, the lid body 21 may be referred to as the operation receiving member 21. An operation area 301 and a display area 302 are formed on a part of the surface of the lid body 21 within the area surrounded by the two-dot chain lines in FIG. 1 and FIG. 3.

As shown in FIG. 3, the operation unit 31 is provided in the operation area 301. The operation unit 31 is composed of characters and figures indicating the target and contents of the operation. The user can set the contents related to the operation of the washing machine 1 by operating the operation unit 31. The operation unit 31 can accept touch operations by the user, and is composed of operation keys that indicate contents such as a "start/pause" key 311, a "wash" key 312a, a "wash and dry" key 312b, a "dry" key 312c, a "wash" key 313a, a "rinse" key 313b, a "spin" key 313c, a "dry" key 313d, a "care" key 313e, a "detergent" key 314a, a "softener" key 314b, a "water flow" key 314c, a "water level" key 314d, a "bath water" key 314e, and a "reservation" key 314f.

As shown in FIG. 3, the display unit 32 is provided within the display area 302. The display unit 32 is composed of characters, figures, etc. that indicate the settings related to the operation of the washing machine 1. The user can check the settings of the washing machine 1 by looking at the display unit 32. The display unit 32 can be composed of a first display unit 321, a second display unit 322, a third display unit 323, and a time display unit 324.

The first display unit 321 is located, for example, at the rear on the right side of the display area 302, and multiple items such as "Lid Lock" 321a and "Child Lock" 321b are selectively displayed as needed. The second display unit 322 is located, for example, at the front on the right side of the display area 302. The second display unit 322 corresponds to, for example, the "Wash" key 312a, the "Wash and Dry" key 312b, the "Dry" key 312c, and the "Care" key 313e of the operation unit 31, and multiple items are selectively displayed as needed.

The third display unit 323 is located, for example, to the left of the display area 302. The third display unit 323 corresponds to, for example, the "Detergent" key 314a, the "Fabric Softener" key 314b, the "Water Flow" key 314c, the "Water Level" key 314d, the "Bath Water" key 314e, and the "Reservation" key 314f of the operation unit 31, and multiple items are selectively displayed as needed. The time display unit 324 is composed of, for example, seven segments that display the set time, remaining time, etc., as four-digit numbers. The time display unit 324 corresponds to, for example, the "Wash" key 313a, the "Rinse" key 313b, the "Spin" key 313c, and the "Dry" key 313d of the operation unit 31, and multiple items are selectively displayed as needed.

As shown in FIG. 2 etc., the operation display device 30 can be configured to have the cover body 21 as the operation receiving member described above, a detection member 40, a display member 50, a support member 60, a substrate 70, and a housing member 80. The detection member 40 has a function of detecting an input operation from a user to the cover body 21. The detection member 40 is configured in a sheet shape using a flexible substrate or the like having a thickness of, for example, about a few millimeters, and is translucent as a whole.

The detection member 40 is attached to the back surface of the lid body 21, that is, the surface opposite the outer surface of the lid 20, which is not exposed to the outside. As described above, the lid body 21 can be made of, for example, hard glass, that is, a material harder than the detection member 40. In this case, the lid body 21 is made of a material that is less likely to deform than the detection member 40, making it easier to assemble the detection member 40 when manufacturing the operation display device 30.

Between the back surface of the lid body 21 and the surface of the detection member 40, that is, on the entire surface where the lid body 21 and the detection member 40 face each other, an adhesive member 401 made of, for example, double-sided tape, adhesive, sticky agent, etc. is provided, as shown by hatching in FIG. 4. That is, the detection member 40 is indirectly fixed to the lid body 21 via the adhesive member 401. In this embodiment, the adhesive member 401 is made of double-sided tape. In this case, the adhesive member 401 is made of, for example, a foamed resin sheet with adhesive or sticky agent applied to both sides, and is made of a substantially uniform thickness. Therefore, the lid body 21 and the detection member 40 are arranged at a distance corresponding to the thickness dimension of the adhesive member 401.

There is no other member between the lid body 21 and the detection member 40 other than the adhesive member 401 for fixing the two together. In this way, by configuring the lid body 21 and the detection member 40 so that no other member than the adhesive member 401 is provided between the lid body 21 and the detection member 40, the gap between the lid body 21 and the detection member 40 can be controlled to the thickness dimension of the adhesive member 401, i.e., a relatively uniform dimension.

As shown in FIG. 4, the detection member 40 has a detection electrode 41 and a connection portion 42. The detection electrode 41 is formed as an electrode pattern and is for detecting a change in capacitance. The operation display device 30 can detect a user's input operation, in this case a touch operation, by detecting a change in capacitance between the detection electrode 41 and the user's finger. A plurality of detection electrodes 41 are provided corresponding to the operation portion 31. The connection portion 42 is connected to each detection electrode 41 via wiring (not shown). A plurality of connection portions 42, in this case two, are provided, and each is electrically connected to the substrate 70.

As shown in Figs. 2 and 5, the display member 50 is formed in a substantially rectangular plate shape, and is configured with a thickness of, for example, about a few tenths of a millimeter. The display member 50 is disposed on the back side of the detection member 40, and is provided in contact with the back side of the detection member 40. In other words, the detection member 40 is disposed on the operation display device 30, closer to the surface operated by the user than the display member 50. The display member 50 and the detection member 40 are not fixed to each other.

The display member 50 has a light-shielding portion 51, a light-transmitting portion 52, and a through hole 53. The light-shielding portion 51 is composed of a transparent plate material made of, for example, synthetic resin or glass, coated with a paint having light-shielding properties. The light-shielding portion 51 has light-shielding properties and occupies the majority of the display member 50. As shown in FIG. 5, the light-transmitting portion 52 is provided at a position corresponding to the operation unit 31 and the display unit 32, and is composed of characters, figures, etc. corresponding to the operation unit 31 and the display unit 32. The light-transmitting portion 52 is composed of so-called blank printing, and has light-transmitting properties.

The display member 50 is indirectly fixed to and supported by the support member 60. The display member 50 is attached to the support member 60 by an adhesive member 501, which is, for example, a double-sided tape. In this case, the adhesive member 501 is, for example, formed by attaching an adhesive or a pressure sensitive adhesive to both sides of a foamed resin sheet, and is configured to have a substantially uniform thickness. And, between the display member 50 and the support member 60, there is no other member than the adhesive member 501 for fixing the two. As shown by hatching in FIG. 6, the adhesive member 501 is provided in the outer peripheral part of the light transmitting part 52, excluding the light transmitting part 52. As shown in FIG. 5 and FIG. 6, the through hole 53 is provided by penetrating the display member 50 in the thickness direction, for example, in a circular or elliptical shape. A plurality of through holes 53, in this case two, are provided.

The support member 60 is made of, for example, synthetic resin and is configured to have light-shielding properties. The support member 60 is formed, for example, in a rectangular shape extending in the left-right direction as a whole. The support member 60 is configured with an outer diameter larger than the outer diameter of the display member 50 and supports the display member 50. The outer diameter of the support member 60 is configured to be slightly smaller than the inner diameter of the hole 222 of the first holding member 22. Furthermore, as shown in FIG. 2, the surface side of the support member 60 is covered by the lid body 21. In other words, the lid body 21 is configured with an outer diameter larger than the outer diameter of the support member 60. The support member 60 has a display member mounting portion 601. The display member mounting portion 601 is, for example, planar and forms the surface of the support member 60, and the display member 50 is mounted on the surface via an adhesive member 501.

The support member 60 can be configured to have a through hole 61 and a guide portion 62. As shown in FIG. 2, the through hole 61 is provided at a position corresponding to the through hole 53, and is provided to penetrate the support member 60 in the thickness direction, for example, in a circular or elliptical shape. A plurality of through holes 61, in this case two, are provided. When the display member 50 is attached to the support member 60, the through hole 61 functions as a positioning portion for aligning the display member 50 and the support member 60 together with the through hole 53. The inner diameter dimension of the through hole 61 is configured to be approximately the same as the inner diameter dimension of the through hole 53. Then, by inserting a pin-shaped jig (not shown) into the through hole 53 and the through hole 61 with the through hole 53 and the through hole 61 arranged in an overlapping position, the horizontal movement of the display member 50 is restricted, and the installation position of the display member 50 relative to the support member 60 is determined.

The support member 60 is not limited to having a through hole 61, and may have a protrusion formed at a position corresponding to the through hole 53 and protruding toward the surface side of the operation display device 30. The outer diameter of the protrusion can be slightly smaller than the inner diameter of the through hole 53. Then, by inserting the protrusion into the through hole 53, the display member 50 can be easily positioned relative to the support member 60.

The guide parts 62 are provided in a number of positions corresponding to the light-transmitting parts 52 of the display member 50, i.e., the operation part 31 and the display part 32. The guide parts 62 can be configured in a cylindrical shape, a square tube shape, a cone shape whose inner diameter gradually decreases toward the rear side of the operation display device 30 (in this case, the lower part), or the like.

The substrate 70 is configured, for example, in a rectangular shape. In addition to the multiple light sources 71, the substrate 70 can be configured to have a current supply circuit for the light sources 71, a signal processing circuit for the detection electrodes 41, and a control device, although details are not shown. The light sources 71 are for displaying the operation unit 31 and the display unit 32 on the cover body 21. As shown in FIG. 8, each light source 71 is configured, for example, as an LED and is mounted on the substrate 70, and is arranged in a space partitioned by the corresponding guide unit 62.

As shown in FIG. 7, the substrate 70 is disposed on the back side of the display member 50 and the support member 60. In this case, the substrate 70 is separated from the display member 50 in the thickness direction of the operation display device 30 via the support member 60. The light from the multiple light sources 71 is individually guided upward, that is, toward the display member 50, by each guide portion 62. In this case, the support member 60 and the display member 50 are precisely positioned and in close contact with each other via the adhesive member 501, so that when the light source 71 emits light, the intended light is emitted from the translucent portion 52. This makes it possible to suppress the occurrence of appearance defects such as the display portion 32, which is not intended to be displayed, being faintly visible from the outside when the light source 71 emits light.

In this configuration, when the light source 71 is turned on, the light from the turned on light source 71 passes through the guide portion 62 of the support member 60, the translucent portion 52 of the display member 50, the detection member 40, and the operation area 301 and display area 302 of the lid body 21. In this way, the contents of the operation unit 31 and the display unit 32 corresponding to the turned on light source 71 are projected and displayed on the surface side of the lid body 21. This allows the user to visually recognize the operation unit 31 and the display unit 32, and allows the user to operate the operation unit 31.

As shown in FIG. 2, the housing member 80 is made of, for example, synthetic resin, and is formed into a rectangular box shape with a bottom that extends in the left-right direction as a whole. The housing member 80 is configured to be attachable to the support member 60 by, for example, a snap fit. The housing member 80 is also attached to the first holding member 22 by, for example, screw fixing. The housing member 80 is capable of housing a substrate 70. When housed in the housing member 80, the substrate 70 is covered with a potting resin (not shown) except for the light source 71, ensuring moisture resistance and insulation.

As shown in FIG. 7, the storage member 80 can be configured to have a wall portion 81, a bottom portion 82, a support member 83, and a pressing member 84. The wall portion 81 is open at one end in the front-rear direction of the operation display device 30, in this case the upper end, and covers the periphery of the substrate 70. The bottom portion 82 is disposed at the other end of the wall portion 81, in this case the lower end. As shown in FIG. 7, the bottom portion 82 has an extension portion 821. The extension portion 821 extends outward more than the wall portion of the wall portion 81. The area of the bottom portion 82 is increased by the extension portion 821, improving the self-supporting ability of the storage member 80.

As shown in FIG. 7 etc., the support member 83 and the pressing member 84 are formed to protrude inward from the wall portion 81. A plurality of support members 83 and pressing members 84 are provided, and the pressing members 84 are arranged around the support member 83. The support member 83 can contact the bottom surface of the substrate 70. The pressing member 84 can contact the top surface of the substrate 70. The pressing member 84 functions as a mechanism for supporting the substrate 70 in cooperation with the support member 83.

The operation display device 30 is manufactured, for example, by the following procedure. First, the detection member 40 is fixed by the adhesive member 401 at a predetermined position on the back surface of the cover body 21, that is, the surface opposite to the surface operated by the user. Then, the housing member 80 in which the substrate 70 is housed and the support member 60 to which the display member 50 is previously attached by the adhesive member 501 are assembled together. Next, the cover body 21 is fixed to the front side of the first holding member 22, and the housing member 80 is fixed to the back side of the first holding member 22. At this time, the support member 60 is housed inside the hole portion 222 of the first holding member 22, as shown in FIG. 7. As a result, the cover body 21, the detection member 40, the display member 50, the support member 60, the substrate 70, and the housing member 80 are integrated to obtain the operation display device 30.

According to the embodiment described above, the washing machine 1 includes a main body 10, a lid 20, and an operation display device 30. The lid 20 opens and closes the opening at the top of the main body 10. The operation display device 30 is provided on either the main body 10 or the lid 20, and is used to set operation settings. The operation display device 30 has an operation receiving member 21 and a detection member 40. The operation receiving member 21 is disposed on the front surface of the operation display device 30. The detection member 40 is attached to the back surface of the operation receiving member 21, and detects input operations from the user to the operation receiving member 21.

For example, if there is variation in the touch sensitivity of the operation display device, this may result in problems such as erroneous or inability to recognize touch. Furthermore, variation in touch sensitivity occurs due to the influence of variation in the distance between the operation surface operated by the user and the member that detects the user's operation. Therefore, by attaching the detection member 40 to the operation receiving member 21, it becomes easier to numerically manage the gap between the operation receiving member 21 operated by the user and the detection member 40, and the variation in the touch sensitivity of the operation display device 30 can be reduced, i.e., the touch sensitivity can be improved.

The operation display device 30 further includes a substrate 70, a display member 50, and a support member 60. The substrate 70 is disposed on the back side of the operation receiving member 21. The substrate 70 includes a light source 71 for displaying an operation section 31 that receives user operations on the operation receiving member 21. The display member 50 is disposed on the back side of the detection member 40. The display member 50 is provided at a position corresponding to the operation section 31 and includes a light-transmitting section 52 through which light from the light source 71 can pass. The support member 60 is configured to be able to guide light from the light source 71 toward the display member 50, and supports the display member 50.

By supporting the display member 50 with the support member 60, the display member 50 can be positioned with high precision relative to the support member 60. This makes it possible to suppress light leakage from the display member 50 when the light source 71 emits light. This makes it possible to suppress the occurrence of malfunctions in the operation display device 30.

Furthermore, the detection member 40 is formed in a sheet shape. The operation receiving member 21 and the detection member 40 are fixed via an adhesive member 401 provided on the entire surface where the operation receiving member 21 and the detection member 40 face each other. This allows the operation receiving member 21 and the detection member 40 to be in close contact with each other while being spaced apart approximately uniformly by a thickness of the adhesive member 401. This further reduces the variation in the user's touch sensitivity to the operation display device 30.

In addition, the operation receiving member 21 is formed from a material that is harder than the detection member 40. By forming the operation receiving member 21 from a material that is harder than the detection member 40, that is, a material that is less likely to deform, the detection member 40 can be easily assembled to the operation receiving member 21, and the operation receiving member 21 and the detection member 40 can be fixed together with greater precision.

The operation receiving member 21 is formed of a plate-like member and covers the front side of the support member 60. By configuring the operation receiving member 21 with a size that allows it to cover the support member 60, it is possible to easily align the operation receiving member 21 and the support member 60 when assembling them. This improves the ease of assembly of the operation display device 30.

Furthermore, the detection member 40 and the display member 50 are not fixed to each other. This makes it possible to omit positioning of the detection member 40 and the display member 50 at the time of manufacturing the operation display device 30, thereby improving the assembly workability of the operation display device 30. As a result, the assembly efficiency of the washing machine 1 can be improved.

Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This new embodiment can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
