DETAILED DESCRIPTION OF THE INVENTION

[0010] The following embodiments relate to a metal-air generator (hereinafter simply referred to as a "generator") shown in the drawings, and include not only essential configurations of the invention but also optional and preferred configurations.

[0011] 1 and 2, the portable generator 10 includes a case body 20 and a top cover 30. When viewed from the front, the case body 20 is generally rectangular and includes a first case side 21 on the left side, a second case side 22 on the right side, and a central case 23 sandwiched between the first and second case sides 21 and 22. The first and second case sides 21 and 22 are each flat and face each other. The central case 23 is rectangular and tubular with its axis extending in the left-right direction when viewed from the front. The top cover 30 is attached to the case body 20 via an engaging portion (FIG. 4) so ​​as to be able to open and close. The case body 20 and the top cover 30 can be formed from a non-conductive material, such as a hard plastic material.

[0012] The internal space of the case body 20 houses a power generation tank 40. The power generation tank 40 has a plurality of negative electrode panels 50 and a plurality of positive electrode housings 60 that house the negative electrode panels 50. The negative electrode panels 50 have plate-shaped anode bodies (FIG. 9), and the positive electrode housings 60 have plate-shaped cathode bodies (FIG. 10). The plurality of positive electrode housings 60 are connected to each other to form a single positive electrode housing assembly 60A.

[0013] An air intake port 201 is formed on the rear side of the case central portion 23, and an air exhaust port 202 is formed on the front side of the case central portion 23. The air intake port 201 is for taking in outside air into the inside of the case body 20, and the air exhaust port 202 is for discharging air inside the case body 20 to the outside. A cooling fan 203 corresponding to the air intake port 201 and a cooling fan 204 ( FIG. 8 ) corresponding to the air exhaust port 202 are provided inside the case body 20. As a result, air flow direction 205 is from the rear side of the case body 20 through the inside of the case body 20 toward the front side of the case body 20. In addition, air vents 206, 207, 208, and 209 are formed in the case central portion 23, and an air vent 210 is formed in the case second side portion 22.

[0014] A control circuit 221 for the generator 10 is provided inside the case body 20. A plurality of LED lamps 222 (indicators) that indicate the remaining battery capacity of the generator 10 are arranged on the outer surface of the first case side portion 21. A user of the generator 10 can check the remaining battery capacity based on the lighting color and blinking interval of the LED lamps 222, and can easily identify when it is time to replace the power generation tank 40 and / or its components. A DC 12V output terminal 223 and a USB output terminal 224 for extracting power generated from the power generation tank 40 are provided on the rear side of the case center portion 23.

[0015] Two power generation tank holding guides 231 are provided on the bottom side inside the case main body 20. The power generation tank holding guides 231 are guide grooves (dovetail grooves) for guiding the positive electrode housing assembly 60A. Two connecting shaft set holes 233 are formed on the front and back sides inside the case main body 20. The connecting shaft set holes 233 are holes that receive one end of a connecting shaft 67 for connecting multiple positive electrode housings 60.

[0016] A protrusion 68 (dovetail) is formed on the underside of the positive electrode housing assembly 60A. The protrusion 68 of the positive electrode housing assembly 60A is inserted into the power generation tank holding guide 231 inside the case body 20, and the positive electrode housing assembly 60A is pushed in from right to left when viewed from the front. Then, one end of the connecting shaft 67 is inserted into the connecting shaft set hole 233, whereby the positive electrode housing assembly 60A is housed within the case body 20.

[0017] The case first side 21 is fixed to the case central portion 23. Two connecting shaft set holes 235 are formed on the inside of the case second side 22. The connecting shaft set hole 235 is a hole that receives the other end of the connecting shaft 67. With the positive electrode housing assembly 60A housed in the case main body 20, the case second side 22 is abutted against the right side of the positive electrode housing assembly 60A when viewed from the front. Then, the other end of the connecting shaft 67 is inserted into the connecting shaft set hole 235, and the case second side 22 is fixed to the case central portion 23 with four case fixing bolts 237.

[0018] A portion of the top surface of the case center portion 23 is opened. With the positive electrode housing assembly 60A housed in the case main body 20, the negative electrode panel 50 is inserted into the positive electrode housing 60 through the opening in the top surface of the case center portion 23. Then, the negative electrode plug 57 provided on the negative electrode panel 50 is connected to the negative electrode terminal 225 provided on the case main body 20.

[0019] Referring to FIG. 2, the upper surface of the case body 20 is formed with four upper connecting holes 241 (recesses), and the lower surface of the case body 20 is formed with four lower connecting members 242 (protrusions). Referring to FIG. 3, two generators 10A and 10B having the same configuration as the generator 10 are prepared, and the lower connecting members 242 of the generator 10A are inserted into the upper connecting holes 241 of the generator 10B to form the generator unit 100 in which the two generators 10A and 10B are stacked. The generator unit 100 has four connecting portions 24. The output voltages of the two generators 10A and 10B may be connected in series or in parallel. Note that while FIG. 3 shows two generators 10A and 10B stacked, this is not limiting and three or more generators may also be stacked.

[0020] 4 shows the generator 10 with the top cover 30 removed. Four engaging protrusions 31 are formed on the top cover 30, and four engaging recesses 25 are formed on the case body 20. The top cover 30 can be opened and closed relative to the case body 20 by inserting and removing the engaging protrusions 31 into and from the engaging recesses 25.

[0021] 5 shows the generator 10 with the top lid 30 and rubber cover 35 removed. The rubber cover 35 is sandwiched between the top lid 30 and the power generation tank 40. The rubber cover 35 is made of a rubber material that has excellent insulating, waterproof, and flexible properties, and has a complex shape that fits the top end of the power generation tank 40. The rubber cover 35 protects the top end of the power generation tank 40 mechanically and electrically, and also has a waterproof function to prevent leakage of the reaction solution inside the power generation tank 40.

[0022] 6 and 7 show a state in which one negative electrode panel 50 is partially pulled out from the positive electrode housing 60, and a state in which the negative electrode panel 50 is completely pulled out. First, the negative electrode plug 57 of the negative electrode panel 50 is removed from the negative electrode terminal 225 of the case body 20. Then, by hooking the handle 56 of the negative electrode panel 50 with your fingers and lifting it, the negative electrode panel 50 can be removed from the positive electrode housing 60. To insert the negative electrode panel 50 into the positive electrode housing 60, the above steps are reversed.

[0023] Referring to Figure 8, the internal wiring of the generator 10 is shown. The power generating cell 41 is composed of a positive electrode housing 60 and a negative electrode panel 50 inserted into the positive electrode housing 60. When water is poured into the positive electrode housing 60, a voltage is generated from the power generating cell 41. The output voltages of the multiple power generating cells 41 are connected in series and input to a control circuit 221. The control circuit 221 converts the input voltage to a predetermined voltage using a built-in DC-DC converter and outputs it to an LED lamp 222, a DC 12V output terminal 223, a USB output terminal 224, and cooling fans 203 and 204.

[0024] At this time, the control circuit 221 supplies power to the cooling fans 203, 204 via the temperature switch 226. The temperature switch 226 is installed inside the case body 20 (see FIG. 11), and turns on to supply power when the temperature inside the case body 20 is equal to or higher than a set value, and turns off to stop the power supply when the temperature inside the case body 20 is equal to or lower than the set value. Note that the control circuit 221 may use a temperature sensor instead of the temperature switch 226, and control the cooling fans 203, 204 based on information from the temperature sensor.

[0025] 9, negative electrode panel 50 includes anode body 51 made of a flat metal, chemical agent 52 that dissolves in water to form a reaction liquid, and bag body 53 made of a water-permeable material and enclosing chemical agent 52. Bag body 53 is positioned so as to surround anode body 51. Because bag body 53 containing chemical agent 52 is positioned so as to surround anode body 51, chemical agent 52 that dissolves in water from bag body 53 can easily reach anode body 51.

[0026] In this embodiment, the bag 53 is formed by folding a single bag in two and is arranged to sandwich both main surfaces (first main surface 511 and second main surface 512) of the anode assembly 51. The bag 53 is divided into a plurality of small pouches 54 in which drug 52 is enclosed. The plurality of small pouches 54 are arranged in a plane so as to face both main surfaces (first main surface 511 and second main surface 512) of the anode assembly 51, respectively. The anode assembly 51 and the bag 53 are sandwiched between two window frames 55.

[0027] The bag 53 folded in half becomes rectangular when unfolded. The bag 53 is divided into a first bag 531 and a second bag 532 along a fold 533. The first bag 531 faces the first main surface 511 of the anode assembly 51, and the second bag 532 faces the second main surface 512 of the anode assembly 51. The first bag 531 is divided into a plurality of pouches 54 in which the drug 52 is evenly packed. In this embodiment, the first bag 531 has eight pouches 54, two in the horizontal direction and four in the vertical direction. The same applies to the second bag 532.

[0028] In this embodiment, one bag body 53 is folded in half to separate it into a first bag body 531 and a second bag body 532. According to this embodiment, the number of bags is halved compared to when the first bag body 531 and the second bag body 532 are two separate bags, thereby reducing manufacturing costs. Furthermore, the anode body 51 can be accurately positioned and fixed simply by aligning the bottom edge 513 of the anode body 51 with the fold 533 of the bag body 53.

[0029] The pouches 54 in the first bag 531 are arranged in a plane facing the first main surface 511 of the anode assembly 51. This reduces uneven distribution of the drug 52 on the first main surface 511 of the anode assembly 51, allowing the reaction on the first main surface 511 to proceed evenly, resulting in stable output. The same applies to the second main surface 512 of the anode assembly 51. From the standpoint of effectiveness and manufacturing costs, the number of pouches 54 in the first bag 531 is preferably one to five in the horizontal direction and two to seven in the vertical direction, for a total of two to thirty-five, more preferably one to three in the horizontal direction and three to five in the vertical direction, for a total of three to fifteen, and most preferably two in the horizontal direction and four in the vertical direction, for a total of eight. The same applies to the pouches 54 in the second bag 532.

[0030] The anode body 51 is in the shape of a rectangular thin plate and can be made of an electrode active material with a relatively high ionization tendency, such as metallic magnesium, aluminum, or zinc. A negative electrode plug 57 made of a conductive material is connected to a corner of the anode body 51. The negative electrode plug 57 is detachably connected to the negative electrode terminal 225 (see FIG. 1, etc.) of the case body 20.

[0031] The chemical agent 52 may be, for example, EDTA (Ethylene Diamine Tetraacetic Acid), sodium chloride, or a mixture thereof.

[0032] The bag 53 can be formed, for example, from a nonwoven fabric. The gaps or micropores in the fibers of the nonwoven fabric are large enough to supply a reaction solution in which the chemical 52 is dissolved in water to the anode assembly 51 and the cathode assembly 61 (see FIG. 13, etc.) and to allow precipitates such as magnesium hydroxide to pass through the nonwoven fabric and settle within the bag 53 without being exposed to the outside. To facilitate the passage of the reaction solution, the gaps in the fibers in the lower portion of the bag 53 may be larger than the gaps in the fibers in the upper portion. Alternatively, instead of a nonwoven fabric, the bag 53 may be formed using a rectangular mesh-shaped fibrous nonwoven fabric sheet made of plastic film, natural fiber, synthetic resin fiber, or the like, or a laminated sheet of film and nonwoven fabric. The size of the mesh in this case is similar to the gaps in the fibers in the case of a nonwoven fabric. The shape of the bag 53 is not limited to a bifold shape; for example, a single bag may be further processed into a bag shape to cover the entire anode assembly 51.

[0033] The two window frames 55 are integrated by detachably fitting their peripheral edges together while sandwiching the bag body 53, thereby maintaining the state in which the bag body 53 is positioned on both main surfaces of the anode body 51. The window frame 55 has multiple lattice-shaped windows and is made of insulating material, such as synthetic resin. A handle 56 is formed at the upper end of the window frame 55. A user can hook their fingers into the handle 56 and pull it upward.

[0034] Referring to FIG. 10 , the positive electrode housing 60 has two cathode bodies 61 (air electrodes), a positive electrode panel 62, and four window frames 63. The positive electrode panel 62 has a rectangular frame shape overall, with window frames 63 fitted into both main surfaces of the frame, and further window frames 63 are provided on the outside of the window frames 63, sandwiching the cathode body 61. The positive electrode panel 62 and the two outer window frames 63 are integrated by overlapping their mounting holes 64 and passing pins through them. The cathode body 61 and window frames 63 are rectangular, and the cathode body 61 is slightly smaller than the window frames 63. The window frame 63 has multiple windows in a lattice pattern.

[0035] The interior of the positive electrode panel 62 is large enough to accommodate the negative electrode panel 50 (see FIG. 9, etc.). An opening 65 is formed at the top end of the positive electrode panel 62, and the negative electrode panel 50 can be inserted or removed through the opening 65, and water can be poured in through the opening 65. Connecting through-holes 66 are formed on both side surfaces of the positive electrode panel 62. By passing a connecting shaft 67 (see FIG. 1) through the through-holes 66 of the multiple positive electrode housings 60, a positive electrode housing assembly 60A (see FIG. 1) consisting of multiple positive electrode housings 60 is obtained.

[0036] The cathode body 61 can be made of a metal with good electrical conductivity, such as gold, silver, a copper alloy, activated carbon, silver chloride, or stainless steel. In addition to being formed from a single layer, the cathode body 61 can also be formed from multiple layers, for example, consisting of a first layer (electrode layer) made of a conductive material such as carbon, a second layer (active layer) made of a positive electrode active material such as activated carbon attached to one side of the first layer, and a plate-like third layer (current collecting layer) made of a conductive metal attached to the other side of the first layer, in order to improve electromotive force and current collecting performance. Furthermore, the first and / or third layers of the cathode body 61 may be mesh-shaped to facilitate air intake.

[0037] 11, a positive terminal 69 is connected to the positive panel 62 of the positive housing 60. Six positive housings 60 are stacked from one end to the other to form a positive housing assembly 60A. The positive terminal 69 of the power generating cell 41 located at one end is connected to the negative terminal 225 of the adjacent power generating cell 41, and this process is repeated up to the power generating cell 41 located at the other end. As a result, the output voltages of the six power generating cells 41 are connected in series, and a "+" potential is obtained from the positive terminal 69 of the power generating cell 41 located at one end, and a "-" potential is obtained from the negative terminal 225 of the power generating cell 41 located at the other end.

[0038] Fig. 12[A] is a side view of the generator 10, and Fig. 12[B] is a cross-sectional view taken along line BB in Fig. 12[A]. Fig. 12[B] mainly shows the cross-sectional structure of the power generation tank 40. Fig. 13 is a cross-sectional view of the power generation cell 41 (negative electrode panel 50 and positive electrode housing 60). Fig. 13 shows the cross-sectional structure of the power generation cell 41 that constitutes the power generation tank 40. The operation of the generator 10 will be described with reference to Figs. 12 and 13.

[0039] The generator 10 includes a case body 20 and a power generation tank 40 housed in the case body 20. The power generation tank 40 includes a positive electrode housing 60 having a cathode body 61 and a negative electrode panel 50 inserted into the positive electrode housing 60. First, water 15 is prepared and poured into a plurality of power generation cells 41 (the positive electrode housing 60 into which the negative electrode panel 50 is inserted). The chemical 52 in the negative electrode panel 50 dissolves in the water 15, forming a reaction solution. In the reaction solution, the cathode body 61 in the positive electrode housing 60 and the anode body 51 in the negative electrode panel 50 face each other. When air is introduced into the case body 20 and supplied to the cathode body 61, the reaction solution acts as an oxidation catalyst, causing an ionization reaction between the cathode body 61 and the anode body 51. Specifically, electrons generated from the ionized anode body 51 react with oxygen and water in the reaction solution in the cathode body 61, resulting in a discharge reaction. This generates a potential difference between the cathode body 61 and the anode body 51, generating a predetermined electromotive force. Reaction gases such as hydrogen generated in the power generation tank 40 are released to the outside through the vents 206-210.

[0040] According to generator 10, negative electrode panel 50 is provided with water-permeable bag 53 that encloses chemical 52 that dissolves in water 15 to form a reaction liquid, and thus the preparation of a reaction liquid is not necessary if water 15 is available, thereby improving user convenience. Furthermore, since water 15, rather than a reaction liquid, can be poured into power generation tank 40, even if water 15 is spilled outside power generation tank 40, metal corrosion and the like can be suppressed compared to when the reaction liquid is spilled.

[0041] Referring to Figures 14[A] and 14[B], a generator 11 is disclosed as another embodiment. In Figure 14, parts that are the same as those in the generator 10 described above are designated by the same reference numerals or omitted to avoid redundant description. A large opening 26 that opens upward is formed at the top of the case body 20. A top cover 70 that can be opened and closed is attached to the large opening 26 via a hinge portion 71. A plurality of water inlet ports (openings 65) corresponding to the plurality of power-generating cells 41 that make up the power generation tank are arranged inside the large opening 26. The top cover 70 has a front surface 72 that faces upward when closed and a back surface 73 that faces upward when open. The back surface 73 is provided with a tray 74 that catches dropped water 15 and a plurality of flow paths 75 that guide water from the tray 74 to each opening 65.

[0042] The number of power-generating cells 41 and flow paths 75 is the same, six in this embodiment. The hinge portion 71 comprises a main body-side elongated hole 711 and a lid-side rotating shaft 712. The main body-side elongated hole 711 is formed in the case main body 20. One end of the lid-side rotating shaft 712 is fixed to the top lid 70, and the other end is rotatably inserted into the main body-side elongated hole 711. The tray 74 comprises a protruding piece protruding from the back surface 73, and has a space surrounded by a substantially elliptical shape by the protruding piece. The multiple flow paths 75 are formed in a gutter shape by protruding pieces protruding from the back surface 73 in the same way as the tray 74, and one end is connected to the tray 74 and the other end is connected to each opening 65. The flow paths 75 have a groove-like, gutter-like shape that is open at the top, but they may also be tubular, such as cylindrical.

[0043] When the top lid 70 is opened via the hinge portion 71 from a closed state, the back surface 73 faces upward, revealing the tray 74. When water 15 is poured into the tray 74, the water 15 flows down each flow path 75 into each water inlet (opening 65). This allows the water 15 to be poured evenly and simultaneously into each power-generating cell 41. With the generator 11, the water 15 can be poured into each power-generating cell 41 all at once, compared to pouring the water 15 into each power-generating cell 41 one by one, thereby making the water pouring operation more efficient.

[0044] Further, a ventilation hole 209 is formed below the case body 20 for the purpose of ventilating the inside of the case body 20. A lower end 211 of the ventilation hole 209 is disposed above a bottom surface 212 inside the case body 20. Water 15 spilling out of the opening 65 collects on the bottom surface 212 inside the case body 20, which is located lower than the lower end 211 of the ventilation hole 209. Therefore, it is possible to prevent the water 15 from leaking out of the case body 20 from the lower end 211 of the ventilation hole 209.

[0045] The disclosure of the present invention described above can be summarized at least as follows.

[0046] The negative electrode panel used in a metal-air generator includes an anode body made of a flat metal, a chemical that dissolves in water to form a reaction liquid, and a bag body that encloses the chemical and is made of a water-permeable material, the bag body being positioned to surround the anode body.
