Technical Field
[0004]
[0001] The present invention relates to a display device mounted on an electric device or the like, particularly a display device mounted on a device that generates functional water such as electrolyzed water.
Background Art
[0002] Conventionally, various display devices for indicating the operating state of an electric device have been proposed.
[0003] It includes a light-shielding member for suppressing light leakage between adjacent emission regions. [Effects of the Invention]
[0008] Since the display device of the present invention has the above configuration, light leakage between adjacent or separated emission areas is suppressed, allowing the user to recognize the operating status of the device more intuitively and clearly. [Brief explanation of the drawing]

[Figure 9] This diagram shows the electrical configuration of the functional water generator 100, along with the flow path. [Modes for carrying out the invention]
[0010] Hereinafter, embodiments of the present invention will be described based on the drawings. It should be understood that the drawings include exaggerated expressions and expressions different from the dimensional ratios of actual structures in order to assist in understanding the content of the invention. Also, throughout each embodiment, the same or common elements are denoted by the same reference numerals, and duplicate descriptions are omitted. Furthermore, the specific configurations shown in the embodiments and the drawings are for understanding the content of the present invention, and the present invention is not limited to the specific configurations shown.
[0011] FIG. 1 shows a display device 1 of the present embodiment. The display device 1 is mounted on an electrical device such as a functional water generation device 100 described later, and displays the operating state of the device.
[0012] The display device 1 includes an exterior case 2 having a window 21, a plurality of light-emitting elements 3 arranged inside the exterior case 2, a light guide 4 attached to the window, and a light-shielding member 5 for suppressing light leakage.
[0013] The window 21 is arranged on the front surface of the exterior case 2 and penetrates the exterior case 2. <00****>
[0014] <*******>The light-emitting elements 3 are arranged at positions corresponding to the window 21. For example, light-emitting diodes or the like are applied to the light-emitting elements 3. The light-emitting elements 3 include a plurality of light-emitting elements 31a, 31b, 31c, 32a, 32b, 33a, 33b.
[0015] The light guide 4 guides the light emitted from the light-emitting elements 3 to the outside of the exterior case 2 and emits it from a plurality of emission regions 41. The light guide 4 is formed of a light-transmissive material. It is desirable that the light guide 4 is formed of a material having a light-diffusing effect. For example, the light guide 4 is preferably formed of a translucent and milky white material (more specifically, an acrylic resin). Thereby, light of uniform brightness is emitted from the emission region 41.
[0016] The light guide 4 is attached to the window 21 from the inside of the exterior case 2. In the display device 1 of the present embodiment, the emission surface 42 (tip surface) of the light guide 4 constitutes the same surface as the surface of the exterior case 2.
[0017] On the light-emitting surface 42 of the light guide 4, for example, a light-shielding printed layer is formed, so that the coloring equivalent to the surface of the exterior case 2 is applied. The light-shielding printed layer is formed while avoiding the light-emitting region 41. As a result, a plurality of light-emitting regions 41 are partitioned on the light-emitting surface 42. Then, the light-transmitting property of each light-emitting region 41 is maintained.
[0018] The light-shielding member 5 is disposed between the light-emitting element 3 and the light guide 4. The light-shielding member 5 suppresses light leakage between adjacent light-emitting regions 41. As a result, the visibility of the display device 1 is enhanced, and the operating state of the device can be recognized more intuitively and clearly.
[0019] FIG. 2 shows the front of the display device 1. The display device 1 of the present embodiment has three light-emitting regions 411, 412, and 413. Each of the light-emitting regions 411, 412, and 413 is formed in a circular shape. Buttons 421, 422, and 423 that are operated to switch the operating state of the device are arranged at the central portions of the circumferences of each of the light-emitting regions 411, 412, and 413. The operating states switched by the operations of each of the buttons 421, 422, and 423 and each of the light-emitting regions 411, 412, and 413 are related to each other. As a result, the user can grasp the relationship between his / her own operations and the operating state of the device.
[0020] Since each of the light-emitting regions 411, 412, and 413 is formed in a circular shape, the shapes of each of the buttons 421, 422, and 423 can be circular shapes that fit the fingertips of the user or the like, and the usability of the functional water generator 100 is improved. The "circular shape" includes not only a perfect circle but also an ellipse, an oval, etc., and also includes shapes incorporating design elements approximating them. The shapes of each of the buttons 421, 422, and 423 may be polygonal shapes including a rectangular shape. Also, so that the user can easily distinguish each of the buttons 421, 422, and 423, each of the buttons 421, 422, and 423 may be formed in a different shape.
[0021] The output region 411 is divided into three arc-shaped output regions 411a, 411b, and 411c by the light-shielding printing layer. Similarly, the output region 413 is divided into two arc-shaped output regions 413a and 413b by the light-shielding printing layer. The number of divisions for each output region 411, 412, and 413 can be set arbitrarily. This makes it possible to display the operating status of the device in more detail. Furthermore, a good correspondence between button 421 and output regions 411a, 411b, and 411c, as well as a good correspondence between button 423 and output regions 413a and 413b, is maintained.
[0022] As shown in Figure 2, the light-emitting elements 31a, 31b, and 31c are positioned to correspond to the emission regions 411a, 411b, and 411c. Similarly, the light-emitting elements 32a and 32b are positioned to correspond to the emission region 412. Likewise, the light-emitting elements 33a and 33b are positioned to correspond to the emission regions 413a and 413b. When any button (for example, button 421) is operated, the corresponding light-emitting element (in this case, light-emitting element 31a) emits light, and light is emitted from the corresponding emission region (in this case, emission region 411a).
[0023] In this embodiment, each light-emitting element 31a, 31b, and 31c is positioned offset from its corresponding emission region 411a, 411b, and 411c. This suppresses localized brightness and darkness of the light emitted from the emission regions 411a, 411b, and 411c. The same applies to the positional relationship between light-emitting elements 32a and 32b and the emission region 412, and between light-emitting elements 33a and 33b and the emission regions 413a and 413b.
[0024] Each light-emitting element 31a, 31b, and 31c is positioned radially inward of its corresponding emission region 411a, 411b, and 411c. This allows each light-emitting element 31a, 31b, and 31c to be compactly arranged on the circuit board 35, and also ensures uniform brightness of the light emitted from the emission regions 411a, 411b, and 411c. The same applies to the positional relationship between the light-emitting elements 32a and 32b and the emission region 412, and between the light-emitting elements 33a and 33b and the emission regions 413a and 413b.
[0025] Figure 3 shows the light guide 4 as viewed from inside the outer casing 2. The light guide 4 has an incident surface 43 into which light emitted from the light-emitting element 3 enters. As shown in Figure 1, the light guide 4 is mounted in the outer casing 2 such that the incident surface 43 faces the side of the light-emitting element 3 on the inside of the outer casing 2.
[0026] Recesses 431 and 433 are formed on the incident surface 43 of the light guide 4. Recess 431 is positioned opposite the light-emitting elements 31a, 31b, and 31c. Recess 433 is positioned opposite the light-emitting elements 33a and 33b.
[0027] Figure 4 shows the light guide 4 together with a part of the light shielding member 5. In this figure, the cross section of line AA that bisects the incident surface 43 in Figure 3 is shown.
[0028] Light incident on the light guide 4 from the incident surface 43 is reflected in a complex manner on the surface of the light guide 4 before being emitted from the emission region 41. In this embodiment, since a part 521 of the light-shielding member 5 is fitted into the recess 431 of the light guide 4, a part 521 of the light-shielding member 5 is embedded inside the light guide 4. This restricts the optical path inside the light guide 4, preventing, for example, light emitted from the light-emitting element 31a from emitting to the outside of the outer casing 2 from the uncorresponding emission regions 411b and 411c. Similarly, since a part 523 of the light-shielding member 5 is fitted into the recess 433 of the light guide 4, preventing, for example, light emitted from the light-emitting element 33a from emitting to the outside of the outer casing 2 from the uncorresponding emission region 413b. Therefore, light leakage between adjacent or separated emission regions 41 is further suppressed, improving the visibility of the display device 1.
[0029] The depth of the recesses 431 and 433 (the thickness of parts 521 and 523 of the light-shielding member 5 embedded in the recesses 431 and 433) is preferably 50% or more of the thickness of the light guide 4. With such a light guide 4 and light-shielding member 5, light leakage between adjacent or separated emission regions 41 is further suppressed.
[0030] Figure 5 shows a cross-section of the display device 1. As shown in Figures 1 and 5, a plate-shaped or film-shaped touch sensor 6 is provided between the light-emitting element 3 and the light guide 4. The touch sensor 6 is a non-contact switch that detects capacitance and pressure.
[0031] The touch sensor 6 is translucent so that light emitted from the light-emitting element 3 can be transmitted to the light guide 4. The incident surface of the touch sensor 6 (the surface facing the light-emitting element 3) may be partially provided with a light-shielding printed layer. The light-shielding printed layer is formed avoiding the area facing the emission region 41. Such a light-shielding printed layer further suppresses light leakage between adjacent or separated emission regions 41.
[0032] The touch sensor 6 detects fluctuations in capacitance and pressure in the area behind buttons 421, 422, and 423, and transmits the corresponding electrical signals to the control unit 107 of the electrical device equipped with the display device 1 (see Figure 9, described later). Based on the electrical signals transmitted from the touch sensor 6, the control unit 107 recognizes that buttons 421, 422, and 423 have been operated and changes the operating mode of the electrical device.
[0033] As shown in Figure 1, the light-emitting elements 31a, 31b, 31c, 32a, 32b, 33a, and 33b are surface-mounted on a circuit board 35 located on the back side of the first light-shielding member. The circuit board 35 is positioned approximately parallel to the front of the outer casing 2. This configuration simplifies the structure and manufacturing process of the display device 1.
[0034] The light-shielding member 5 of this embodiment includes a first light-shielding member 51 disposed between the circuit board 35 and the touch sensor 6, and a second light-shielding member 52 disposed between the touch sensor 6 and the light guide 4. With this configuration, the touch sensor 6 is sandwiched between the first light-shielding member 51 and the second light-shielding member 52, further suppressing light leakage between adjacent or separated emission areas 41.
[0035] Figure 6 shows the first light-shielding member 51. The first light-shielding member 51 has an outer peripheral portion 511 that covers the entire radially outer side of each window 21 when viewed from the direction normal to the touch sensor 6 (the optical axis L of the light guide 4 (see Figure 5)). The outer peripheral portion 511 prevents light emitted from the light-emitting elements 31a, 31b, and 31c from leaking out of emission areas 412, 413, etc., that do not correspond to the light-emitting elements 31a, 31b, and 31c. The same applies to light emitted from the light-emitting elements 32a, 32b and light emitted from the light-emitting elements 33a, 33b.
[0036] The first light-shielding member 51 has a radiating portion 512 that extends radially from the center of the arc of the window 21 to the outer peripheral portion 511. The radiating portion 512 prevents light emitted from, for example, the light emitted from the light-emitting element 31a from leaking out from emission regions 411b, 411c, etc., that do not correspond to the light-emitting element 31a. The same applies to light emitted from light-emitting elements 31b, 31c and light emitted from light-emitting elements 33a, 33b.
[0037] Figure 7 shows the second light-shielding member 52. The second light-shielding member 52 is fitted into the recesses 431 and 433 (see Figure 3) of the light guide 4 as parts 521 and 523 of the light-shielding member 5. As a result of this second light-shielding member 52, light leakage between adjacent emission regions 41 is further suppressed. More specifically, the second light-shielding member 52 prevents light emitted from the light-emitting element 31a from leaking from emission regions 411b, 411c, etc., that do not correspond to the light-emitting element 31a. The same applies to light emitted from light-emitting elements 31b, 31c, 33a, and 33b.
[0038] It is desirable that the second light-shielding member 52 overlaps with the radiating portion 512 of the first light-shielding member 51 when viewed from the direction normal to the touch sensor 6. With this configuration, the synergistic effect of the radiating portion 512 of the first light-shielding member 51 and the second light-shielding member 52 further suppresses light leakage between adjacent emission regions 41.
[0039] Figure 8 shows a functional water generator 100, which is one form of electrical equipment equipped with the display device 1 of this embodiment. Note that the display device 1 is broadly applicable to electrical equipment, and the following description does not limit the scope of application of the display device 1 to the functional water generator 100.
[0040] The functional water generator 100 comprises a functional water generation unit 102 that generates functional water, an operation unit 106 for the user to select a mode for the functional water generation unit 102, a control unit 107 that controls the functional water generation unit 102, and a display device 1 for displaying the mode selected by the operation unit 106.
[0041] Raw water is supplied to the functional water generation unit 102. Generally, tap water is used as the raw water, but other types of water, such as well water or groundwater, can also be used.
[0042] The functional water generation unit 102 generates functional water by processing the supplied raw water. "Functional water" is defined as water to which a reproducible useful function has been imparted through artificial treatment, and for which the scientific basis regarding the treatment and function has been clarified or is in the process of being clarified. Functional water includes purified water as well as electrolyzed water, which will be described later.
[0043] The functional water generation unit 102 operates in multiple modes. This allows for the generation of different functional water in each mode. The mode of the functional water generation unit 102 is selected by the user operating the control unit 106 and controlled by the control unit 107.
[0044] The operating unit 106 is comprised of the buttons 421, 422, and 423 (see Figure 2) and the touch sensor 6 (see Figure 1) mentioned above. The number of buttons 421, 422, etc. is not particularly limited.
[0045] The control unit 107 determines one of several modes based on the user's operation of buttons 421, 422, and 423. Then, the control unit 107 operates the functional water generation unit 102 in the determined mode. This generates the treated water desired by the user.
[0046] The control unit 107 includes, for example, a CPU (Central Processing Unit) that performs various calculations and information processing, a program that controls the operation of the CPU, and a memory that stores various types of information.
[0047] Figure 9 shows the electrical configuration of the functional water generator 100, along with the flow path. The relationship between the control unit 107 and each part of the functional water generator 100 will be explained below based on Figure 9.
[0048] The control unit 107 is connected to the functional water generation unit 102, the operation unit 106, and the display device 1. The control unit 107 controls the functional water generation unit 102 and the display device 1 based on electrical signals input from the operation unit 106.
[0049] In the functional water generator 100 of this embodiment, the functional water generated by the functional water generation unit 102 includes, for example, electrolyzed water produced by electrolysis. That is, the modes of the functional water generation unit 102 include an "electrolyzed water mode" that generates electrolyzed water.
[0050] Furthermore, electrolyzed water includes reduced water produced at the cathode and acidic water produced at the anode during electrolysis. In other words, the "electrolyzed water mode" includes a "reduced water (hydrogen water) mode" that produces reduced water through electrolysis and an "acidic water mode" that produces acidic water through electrolysis.
[0051] In Figure 2, buttons 421 and 423 are operated to select the "electrolyzed water mode". More specifically, button 421 is operated to select the "reduced water mode", and when button 421 is operated, the control unit 107 causes the light-emitting elements 31a, 31b, and 31c to light up. Button 423 is operated to select the "acidic water mode", and when button 423 is operated, the control unit 107 causes the light-emitting elements 33a and 33b to light up.
[0052] In this embodiment, it is desirable that the functional water produced by the functional water generation unit 102 includes, for example, purified water. That is, it is desirable that the modes of the functional water generation unit 102 include a "purified water mode" that produces purified water.
[0053] In this case, as shown in Figure 2, button 422 is operated to select "Water Purification Mode". When button 422 is operated, the control unit 107 causes the light-emitting elements 32a and 32b to light up.
[0054] In order to realize the above-mentioned "reduced water mode," "acidic water mode," and "purified water mode," the functional water generation unit 102 of this embodiment includes a water purification cartridge 103 that purifies raw water to produce purified water, and an electrolytic cell 104 that generates reduced water or acidic water by electrolyzing the purified water that has passed through the water purification cartridge 103.
[0055] The water purification cartridge 103 is configured to be detachably attached to the main body of the functional water generator 100. In this embodiment, the water purification cartridge 103 is located upstream of the electrolytic cell 104. The water purification cartridge 103 may also be located downstream of the electrolytic cell 104. In this case, the water purification cartridge 103 purifies the reduced water, acidic water, or raw water that has passed through the electrolytic cell 104 produced by the electrolytic cell 104 to generate purified water.
[0056] The electrolytic cell 104 generates electrolyzed water, i.e., reduced water and acidic water, by electrolyzing the water supplied from the water purification cartridge 103.
[0057] The electrolytic cell 104 includes an electrolytic chamber 140, a first power supply 141, a second power supply 142, and a diaphragm 143. The electrolytic chamber 140 is divided by the diaphragm 143 into a first electrode chamber 140A on the side of the first power supply 141 and a second electrode chamber 140B on the side of the second power supply 142.
[0058] The water purification cartridge 103 and the electrolytic cell 104 are connected by a water supply channel 121. The water supply channel 121 branches into two at a branching point between the water purification cartridge 103 and the electrolytic cell 104, and connects to the first electrode chamber 140A and the second electrode chamber 140B. As a result, purified water purified by the water purification cartridge 103 is supplied to both the first electrode chamber 140A and the second electrode chamber 140B.
[0059] One of the first power supply unit 141 and the second power supply unit 142 is used as an anode power supply unit, and the other is used as a cathode power supply unit. The polarity of the first power supply unit 141 and the second power supply unit 142 can be changed as appropriate depending on the mode of the functional water generation unit 102, etc. Purified water is supplied to both the first electrode chamber 140A and the second electrode chamber 140B of the electrolysis chamber 140, and a DC voltage is applied to the first power supply unit 141 and the second power supply unit 142, causing electrolysis of water to occur in the electrolysis chamber 140.
[0060] The diaphragm 143 is composed of, for example, a polytetrafluoroethylene (PTFE) hydrophilic membrane. In such an electrolytic cell 104, reduced water or acidic water is produced in the first electrode chamber 140A and the second electrode chamber 140B. Reduced water contains dissolved hydrogen gas produced by electrolysis, and acidic water contains dissolved oxygen gas produced by electrolysis. Therefore, the above-mentioned reduced water is also called "electrolyzed hydrogen water." Electrolyzed hydrogen water is attracting attention for its effectiveness in improving gastrointestinal symptoms.
[0061] The first electrode chamber 140A is connected to the first outlet pipe 123, and the electrolyzed water produced in the first electrode chamber 140A is discharged from the first outlet pipe 123. On the other hand, the second electrode chamber 140B is connected to the second outlet pipe 124, and the electrolyzed water produced in the second electrode chamber 140B is discharged from the second outlet pipe 124. Figure 9 shows the functional water generator 100 in "reduced water mode," in which reduced water produced in the first electrode chamber 140A is discharged from the first outlet pipe 123.
[0062] When the functional water generation unit 102 is in reduced water mode or acidic water mode, the control unit 107 applies a DC voltage to the first power supply unit 141 and the second power supply unit 142. The control unit 107 controls the polarity of the first power supply unit 141 and the second power supply unit 142 according to the mode of the functional water generation unit 102.
[0063] Furthermore, the control unit 107 controls the electrolytic current I supplied to the first power supply unit 141 and the second power supply unit 142 according to the pH of the functional water (or, in the case of electrolyzed hydrogen water, the electrolyzed hydrogen concentration). More specifically, the control unit 107 controls the electrolytic current I supplied to the power supply units 141 and 142 by referring to the information stored in the memory based on a signal corresponding to the flow rate per unit time input from the flow sensor 122 provided in the water supply channel 121. The control of the electrolytic current I is achieved by feedback control of the DC voltage applied between the first power supply unit 141 and the second power supply unit 142 by the control unit 107 based on the output signal from the ammeter 144. This controls the electrolysis intensity (electrolysis level) in the electrolytic cell 104.
[0064] The electrolysis strength in the electrolytic cell 104 can be set to increase sequentially, for example, according to the number of times button 421 or 423 is operated consecutively. Here, "operation of button 421 or 423 consecutively" means that either button 421 or 423 is operated multiple times in a row.
[0065] In the functional water generator 100 of this embodiment, it is desirable that the control unit 107 is configured to control the light emission pattern of the light-emitting element 3 according to the number of times the button 421 or 423 corresponding to each mode is operated consecutively. In this configuration, it becomes possible to make the light-emitting element 3 emit light with a light emission pattern corresponding to the electrolysis intensity in the reduced water mode, and the user can easily understand the details of the operation of the functional water generator 102.
[0066] One example of a light emission pattern for the light-emitting element 3 is a configuration in which the light-emitting elements 31a, 31b, 31c, 32a, 32b, 33a, and 33b emit light in a controlled region.
[0067] The control unit 107 changes the number of times the multiple light-emitting elements 31a, 31b, and 31c are illuminated according to the number of times the button 421 is pressed consecutively. Specifically, when the button 421 is pressed once, the control unit 107 illuminates only the light-emitting element 31a. When the button 421 is pressed twice consecutively, the control unit 107 illuminates both the light-emitting elements 31a and 31b. When the button 421 is pressed three times consecutively, the control unit 107 illuminates all three light-emitting elements 31a, 31b, and 31c.
[0068] This configuration corresponds to a setting where the electrolysis intensity in "reduced water mode" is set in three stages. When button 421 is operated four times, the electrolysis intensity returns to the level when button 421 is operated once, and only the light-emitting element 31a emits light (see Figure 4). The same applies when button 421 is operated five or more times.
[0069] Similarly, the control unit 107 changes the number of times the multiple light-emitting elements 33a and 33b are illuminated according to the number of times the button 423 corresponding to "acidic water mode" is pressed consecutively. Also, when the button 422 corresponding to "purified water mode" is pressed, the electrolysis intensity is zero (constant), so the multiple light-emitting elements 32a and 32b illuminate simultaneously. Even if the button 422 is pressed two or more times, the light-emitting elements 32a and 32b continue to illuminate.
[0070] With a display device 1 configured in this way, the user can easily understand the mode of the functional water generation unit 102 and the electrolysis strength in the electrolytic cell 104 by observing the emission state from the emission areas 411a, 411b, 411c, 412, 413a, and 413b located around the periphery of the operated buttons 421, 422, and 423, thereby improving the usability of the functional water generation device 100.
[0071] Although the display device 1 and other components of the present invention have been described in detail above, the present invention is not limited to the specific embodiments described above and can be implemented in various modified forms.
[0072] For example, the light-emitting elements 31a, 31b, and 31c may be configured to emit light in two or more colors. In this case, in the next step after the light-emitting elements 31a, 31b, and 31c emit light in the first color (e.g., blue), the light-emitting elements 31a, 31b, and / or 31c may emit light in the second color (e.g., yellow). Such a configuration corresponds to a form in which the electrolysis intensity in "reduced water mode" is set in four or more stages. Furthermore, by changing the color according to the electrolysis intensity, the user can be alerted to the electrolysis intensity while the functional water generator 100 is operating. The same applies to the light-emitting elements 33a and 33b.
[0073] Similarly, the light-emitting elements 32a and 32b may be configured to emit light in two or more colors. In this case, for example, the light-emitting elements 32a and 32b may be configured to emit light in a second color in order to alert the user when some error occurs in the operation of the functional water generator 100.
