[0007] [Figure 1] FIG. 2 is a perspective view of the electrolytic water generating device. [Diagram 2] FIG. 2 is a diagram showing a usage mode of the electrolytic water generating device. [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] FIG. 1 is a block diagram of an electrolytic water generating device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] 1 is a perspective view of an electrolyzed water generating device 1. In this specification, "electrolysis" may be abbreviated to "electrolysis." The electrolytic water generator 1 is portable and can be connected to a water supply source 252 (FIG. 2) for use, making it easy to use. The case 2 of the electrolytic water generator 1 is made of, for example, resin, and is a generally rectangular parallelepiped shape that is long along a horizontal plane. The case 2 may have any suitable shape. Hereinafter, the longitudinal direction of the case 2 is defined as the X direction, the right direction in FIG. 1 is defined as the +X direction, and the left direction in FIG. 1 is defined as the -X direction. The direction perpendicular to the X direction in the horizontal plane is defined as the Y direction, the front direction in FIG. 1 is defined as the +Y direction, and the back direction in FIG. 1 is defined as the -Y direction. The direction perpendicular to the X direction and the Y direction is defined as the Z direction, the upward direction in FIG. 1 is defined as the +Z direction, and the downward direction in FIG. 1 is defined as the -Z direction.

[0009] The case 2 includes a case body 200 and a lid body 210. The case body 200 is formed in a box shape with an opening 201 on the +Y direction side. The case body 200 is longer in the Y direction than the lid body 210. The lid body 210 closes the opening 201 and is detachably attached to the +Y direction side of the case body 200, or is connected rotatably around the end in the -Z direction to open and close the opening 201. The top surface 211 of the lid body 210 includes an operation display unit 34. The operation display unit 34 includes an operation unit such as a button, key, or touch panel, and receives input from the user so that the user can control the operation of the electrolytic water generating device 1. The operation display unit 34 includes a display unit such as a lamp or a display, and displays whether the power supply of the electrolytic water generating device 1 is ON or OFF.

[0010] The top surface 21, bottom surface 24, and both side surfaces in the X direction of the case body 200 are connected to the top surface 211, bottom surface, and both side surfaces in the X direction of the lid 210. The top surfaces 21, 211 of the case body 200 and the lid 210 form the top surface of the case 2, the bottom surfaces 24 form the bottom surface of the case 2, and both side surfaces in the X direction form both side surfaces in the X direction of the case 2. Of the four side surfaces of the rectangular parallelepiped case 2, the surface located in the +Y direction and appearing on the front side of FIG. 1 is the front surface, and the surface located in the -Y direction is the back surface 28 (see also FIG. 4). The back surface 28 is connected to the end of the top surface 21 in the -Y direction and is aligned along the Z direction.

[0011] The case body 200 accommodates an electrolyte solution tank 31 that stores an electrolyte solution. The electrolyte solution tank 31 is installed on the +X direction side inside the case body 200. In this embodiment, the electrolyte solution tank 31 has a cubic shape that is shorter in the X direction than in the Y direction and longer in the Z direction. The electrolyte solution tank 31 may have an outer shape like a rectangular prism bottle, for example, and may have any other appropriate outer shape. The electrolyte solution tank 31 is disposed along the back surface 28 of the case 2, and is disposed near a corner between the back surface 28 and the side surface of the case 2 in the +X direction. The electrolyte solution tank 31 is disposed, for example, between a flow path 303 (FIG. 5: piping) described later and the back surface 28 of the case 2, overlapping with the flow path 303 (FIG. 5) in the Y direction and shifted in the Y direction from the electrolytic cell 37 described later. In this embodiment, the electrolyte solution tank 31 is disposed by utilizing the dead space in the -Y direction of the flow path 303, so that the electrolytic water generating device 1 can be made compact. The Y direction can also be said to be the depth direction of the case 2, perpendicular to the longitudinal direction of the top surface of the case 2 (X direction) and the opposing direction of the top surface and the bottom surface of the case 2 (Z direction). A lid 232 capable of opening and closing a pouring port 231 for pouring electrolyte solution from the outside into the electrolyte solution tank 31 is provided on the top surface 21 (first surface) of the case body 200. The lid 232 is located in the +Z direction area of ​​the electrolyte solution tank 31, and is located at the end of the top surface 21 in the +X direction.

[0012] The handle 22 is provided on the top surface 21 along the X direction. The handle 22 is made of, for example, resin and is formed integrally with the case 22. On the top surface 21, one end of the handle 22 is on the +X direction side, and the other end of the handle 22 is on the -X direction side on the top surface 21. The lid 232 is on the +X direction side of the one end of the handle 22 in the +X direction. In this manner, in this embodiment, by bringing the one end of the handle 22 in the +X direction closer to the lid 232, the case 2 can be held in a well-balanced manner using the handle 22 even if a heavy electrolyte solution tank 31 is disposed on the +X direction side of the case 2. The handle 22 may be detachable from the case 22, or may be rotatable about both base ends and bendable to be oriented along the outer surface of the case 22.

[0013] The handle 22 includes a top portion 221 and a side portion 222. The top portion 221 is linear and is disposed in such a manner that the height from the top surface 21 increases toward the +X direction side. As a result, in this embodiment, even if a heavy electrolyte solution tank 31 is disposed on the +X direction side of the case 2, the case 2 can be held in a balanced manner by grasping the top portion 221. That is, the case 2 can be held stably in consideration of the weight of the electrolyte solution tank 31. Furthermore, in this embodiment, the side portion 222 of the handle 22 descends from the top portion 221 to the top surface 21, and is fixed in front of the lid 2 (in the -X direction) rather than at the end of the top surface 21 in the +X direction so as to avoid the lid 232 of the electrolyte solution tank 31. In this embodiment, the electrolyte solution tank 31 gradually becomes lighter as the electrolyte solution inside is consumed as the electrolytic water generating device 1 is used. However, when holding the electrolytic water generating device 1 by grasping the handle 22, it becomes easy to keep the electrolytic water generating device 1 level regardless of the weight of the electrolyte solution tank 31.

[0014] The side parts 222 extend linearly from both sides of the top part 221 in the X direction to the top surface 21, and are positioned on both outer sides in the X direction as they move toward the top surface 21. The joint between the top part 221 and the side parts 222 is provided with an attachment hole 223. As shown in FIG. 2, the shoulder belt 41 can be attached to the case 2 using the attachment hole 223. The user can wear the electrolytic water generator 1, for example, behind the waist, by wearing the shoulder belt 41 on the shoulder. The electrolytic water generator 1 may be worn around the waist of the user by attaching a waist wrap instead of the shoulder belt 41. The part for attaching the shoulder belt 41 or waist wrap to the electrolytic water generator 1 can be provided at an appropriate position of the electrolytic water generator 1 in an appropriate shape.

[0015] Fig. 3 is a front view of the case 2. Fig. 4 is a rear view of the case 2. As shown in Fig. 4, the bottom surface 24 (second surface) of the case body 200 is located in a position opposite to the top surface 21. On the -X direction side of the bottom surface 24 (the right side in Fig. 4), a water supply port 25 is provided which protrudes from the bottom surface 24 in the -Z direction and to which a first connection hose 251 is attached. The first connection hose 251 is connected to a water supply source 252 such as a faucet located outdoors or indoors. The electrolyzed water generating device 1 dilutes the generated electrolyzed water with water sent from the water supply source 252 via the first connection hose 251 and the water supply port 25.

[0016] A drain port 26 is provided on the +X direction side (left side in FIG. 4) of the bottom surface 24, protruding from the bottom surface 24 in the -Z direction and to which the second connection hose 261 is attached. The second connection hose 261 is connected to the water discharger 262. The electrolytic water generating device 1 discharges the generated and diluted electrolytic water from the water discharger 262 via the second connection hose 261. The water discharge mode of the water discharger 262 may be a so-called shower or straight, and may be appropriate. In addition, the drain port 26 may be provided on the -X direction side (right side in FIG. 4) of the bottom surface 24, and the water supply port 25 may be provided on the +X direction side (left side in FIG. 4). In this case, the flow path 303 may be located on the -X direction side, and the flow path 301 and the water supply valve 35 may be located on the -X direction side. The water supply port 25 and the drain port 26 may be provided at an appropriate position on the bottom surface 24, or may be provided at a position other than the bottom surface 24.

[0017] The electrolytic water generator 1 includes legs 27. The legs 27 can be attached to and detached from the bottom surface 24, and raise the bottom surface 24 above the surface on which the electrolytic water generator 1 is placed. The legs 27 are, for example, U-shaped with an open end in the +Z direction, and are detachably attached to both sides of the bottom surface 24 in the X direction with screws or the like. Casters (not shown) may be attached to the bottom surface 24 instead of the legs 27, and in this case, the electrolytic water generator 1 can be pulled and moved without having to be held by hand.

[0018] The back surface 28 of the case 2 has a pair of slits 29 for hanging on a wall. The slits 29 open in the -Z direction and have a depth in the +Z direction that allows a hook (not shown) attached to the wall to be inserted with its hook bar facing upward. The electrolytic water generator 1 can be hung on a wall by inserting a pair of hooks (not shown) attached to the wall into the pair of slits 29.

[0019] FIG. 5 is a block diagram of the electrolyzed water generating device 1. The case 2 accommodates an electrolyte solution tank 31, a power storage unit 32, a control unit 33, an operation display unit , a water supply valve 35, a pump , an electrolytic cell 37, and a mixing and dilution unit .

[0020] The electrolyte solution tank 31 stores an electrolyte solution. Examples of electrolyte solutions used to generate acidic electrolyzed water include a mixed solution of salt water and hydrochloric acid, or a mixed solution of citric acid and salt water. Examples of electrolyte solutions used to generate alkaline electrolyzed water include a solution of sodium bicarbonate containing potassium or sodium.

[0021] The power storage unit 32 is charged when an external power source is connected to the electrolytic water generation device 1, and supplies power to each part of the electrolytic water generation device 1, such as the control unit 33, the operation display unit 34, the water supply valve 35, the pump 36, and the electrolytic cell 37. The control unit 33 includes a memory and a processor, and the processor reads a program in the memory to control the entire electrolyzed water generating device 1. A board on which the control unit 33 is mounted is housed in the lid 210 along the X direction. The power storage unit 32 is also housed in the lid 210, for example.

[0022] The water supply valve 35 is an electromagnetic valve or the like under the control of the control unit 33, and opens and closes a flow path 301 of tap water from the water supply port 25 to the mixing and diluting unit 38. The pump 36 is provided in a flow path 302 of the electrolyte solution from the electrolyte solution tank 31 to the electrolytic cell 37 , and is under the control of the control unit 33 , to send the electrolyte solution in the electrolyte solution tank 31 to the electrolytic cell 37 .

[0023] The electrolytic cell 37 is, for example, a single-chamber electrolytic cell in which the anode and cathode are not separated by a diaphragm, and electrolyzes the electrolyte solution to generate acidic electrolyzed water or alkaline electrolyzed water.

[0024] The mixing and dilution unit 38 receives electrolytic water from the electrolytic cell 37, and also receives tap water from the water inlet 25 by opening the water supply valve 35, thereby diluting the electrolytic water. For example, the mixing and dilution unit 38 can dilute the acidic electrolytic water generated in the electrolytic cell 37 into slightly acidic electrolytic water of pH 5 to 6.5. For example, the electrolytic cell 37 is integrated with the mixing and dilution unit 38, and dilutes the electrolytic water by supplying water after electrolysis. The mixing and dilution unit 38 may be a tank or a pipe separate from the electrolytic cell 37, or the electrolytic water may be sent from the electrolytic cell 37 by using a pump, gravity, suction force transmitted from the outlet 26, or the like.

[0025] The electrolytic water diluted by the mixing and diluting unit 38 is sent from the mixing and diluting unit 38 to the drain outlet 26 through the flow path 303, and is further sent from the drain outlet 26 to the water discharger 262 through the second connection hose 261. The flow paths 301 to 303 can be referred to as piping. For example, the flow path 303 can be referred to as piping that connects the mixing and diluting unit 38 and the drain outlet 26.

[0026] In the electrolytic water generating device 1, for example, when the power button of the operation display unit 34 is pressed to turn on the power, the pump 36 operates to send the electrolyte solution from the electrolyte solution tank 31 to the electrolytic cell 37. Then, the electrolyte solution is electrolyzed by the electrolytic cell 37 to generate electrolytic water. When the pump 36 operates, the electrolytic water is sent from the electrolytic cell 37 to the mixing and dilution unit 38, and the water supply valve 35 opens to send tap water to the mixing and dilution unit 38, diluting the electrolytic water. The diluted electrolytic water is sent from the mixing and dilution unit 38 to the water discharger 262. In this way, the electrolytic water generating device 1 can continuously generate useful electrolytic water containing hypochlorous acid (for example, chlorine concentration of 5 ppm to 9 ppm).

[0027] The electrolytic water generating device 1 described above has a built-in power storage unit 32, and can be used anywhere by connecting the water supply port 25 to the water supply source 252. Therefore, the electrolytic water generating device 1 is portable and easy to use, and can be connected to the water supply source 252 in, for example, a toilet, a bathroom, etc., to generate and dilute electrolytic water that can be used for deodorization, sterilization, cleaning, etc. Furthermore, by connecting the electrolytic water generating device 1 to the water supply source 252, it is not necessary to refill it with tap water each time. The electrolytic water generating device 1 has a compact shape with a handle 22 on the top, making it easy to carry, and by using the shoulder strap 41 and legs 27, it is possible to perform cleaning work flexibly without being restricted by the work space. The electrolytic water generator 1 is transportable as described above, and since the water inlet 25 and the drain outlet 26 are provided on the bottom surface 24 of the electrolytic water generator 1, it is possible to prevent the first connection hose 251 of the water inlet 25 and the second connection hose 261 of the drain outlet 26 from bending or twisting, compared to when the water inlet 25 and the drain outlet 26 are provided somewhere other than on the bottom surface 24. The effect of preventing bending or twisting is particularly effective when the first connection hose 251 and the second connection hose 261 are long so that the user can carry the electrolytic water generator 1 while moving around as shown in FIG.

[0028] The present invention can be implemented in the embodiments without departing from its features. The embodiments, modifications, and effects are merely illustrative and should not be construed as limiting the present invention. The features and structures of the embodiments and modifications can be added and combined in various ways to obtain alternative configurations. [Explanation of symbols]
