<Embodiment>
In FIG. 1, 1 shows an electrolyzed water generator as a whole. The electrolyzed water generator 1 is supposed to be used in a factory or the like where water is used. Therefore, the waterproof specifications are provided so that water does not enter the inside of the housing 2 even when water is splashed from above or in the horizontal direction.

The electrolyzed water generator 1 has a rectangular parallelepiped shape, and houses an electrolyzed water generating unit 7 (see FIG. 2) and exhaust fans 6 and 43 inside the housing 2. The exhaust fans 6 and 43 are installed on both the left and right sides of the housing 2 so as to be suspended from the ceiling surface 25C.

The electrolytic water generation unit 7 electrolyzes raw water supplied from the outside (for example, tap water, industrial water, filtered water, etc.) and an aqueous electrolyte solution in which an electrolyte such as salt, sodium carbonate, or hydrochloric acid is dissolved, and electrolyzes the solution. Produces water (eg, acidic electrolyzed water or alkaline electrolyzed water, or acidic electrolyzed water and alkaline electrolyzed water). Raw water and an aqueous electrolyte solution are supplied through a supply connection port (not shown) formed on the rear surface 25B, and electrolyzed water is discharged through a discharge connection port (not shown) formed on the rear surface 25B. A hose is connected to each of the supply connection port and the discharge connection port, and a supply source and a discharge port for raw water and an aqueous electrolyte solution are provided at the tip positions of the hoses.

As shown in FIG. 2, the housing 2 has side panels 3 on the left and right sides that are removable from the housing body 20. The housing body 20 is composed of four surfaces, a front surface 25A on the front side, a rear surface 25B on the rear side, a ceiling surface 25C on the upper side, and a bottom surface 25D on the lower side, and openings on the left and right sides.

FIG. 3 shows a cross-sectional view of the right side panel 3 and the housing body 20 near the center in the front-rear direction. Hereinafter, the right side panel 3 and the housing body 20 will be described, and the description of the left side panel 3 and the housing body 20 having the same configuration will be omitted.

In the side panel 3, a long ventilation port plate 4 is provided on the left and right sides, which is one size larger than the panel hole 31 at a position facing the exhaust fan 6 with respect to the outside (right side in the figure) of the panel hole 31 provided in the side panel 3. It is attached. The ventilation port plate 4 is provided with a through hole 4B and a hood 4A protruding so as to cover the through hole 4B.

The hood 4A has a lower end formed from just above the through hole 4B to a lower side than the through hole 4B, and covers the right side of the through hole 4B in the horizontal direction. In other words, the hood 4A covers the outside of the through hole 4B, and the lower side thereof is open, and even when water is splashed from above or horizontally, the hood 4A enters the inside of the housing 2 through the through hole 4B. It is possible to prevent water from entering.

A filter 5 is attached to the inside of the panel hole 31 of the side panel 3. As a result, it is possible to prevent foreign matter from being mixed from the outside of the electrolyzed water generator 1 through the through hole 4B.

FIG. 4 shows a state in which the inside (left side) of the right side panel 3 is viewed from below. The locking tool 8 is a locking metal fitting for locking and fixing the side panel 3 to the housing body 20 in response to an operation from the outer surface 3A side of the side panel 3.

The side panel 3 has an edge wall 13 (upper edge wall 13C, lower edge wall 13D, front edge wall 13A, and rear edge wall 13B) whose four sides project from the inner side surface 3B. It is formed. The protruding height is the same on all four sides, for example, about 0.5 to 2.0 cm. The upper and front and rear edge walls 13C, edge wall 13A and edge wall 13B have flat portions 13Ab to 13Cb horizontal to the inner side surface 3B. The flat portions 13Ab to 13Cb are, for example, about 0.5 to 2.0 cm, and are formed by bending the tip of the edge wall 13.

The lower edge wall 13D has a plate shape that is substantially upright from the inner side surface 3B, and a flat portion is not formed. The edge wall 13D is provided with recesses 13Da as if the walls were cut out in the vicinity of both ends.

A filter housing portion 10 that stands upright from the inner side surface 3B is formed at a position about 1 to 5 cm above the lower edge wall 13D. The filter accommodating portion 10 is formed long on the left and right sides, and has a prismatic shape having surfaces on the upper and lower sides. The filter storage portion 10 is formed in a grid pattern consisting of only a frame that is completely hollowed out, and the filter 11 is housed inside. The filter storage portion 10 is composed of a storage mechanism 10A which is a grid-like protruding portion and a plate-shaped mounting portion 10B (see FIG. 3), and the side panel 3 is formed by fixing the mounting portion 10B with a screw or the like. It is fixed to.

Elongated protrusions 10C are provided on both front and rear ends of the filter storage portion 10 with a gap 10D interposed therebetween. That is, a gap 10D, which is a recess, is formed at the end of the filter accommodating portion 10. The protruding portion 10C is formed to be smaller than the length of the filter accommodating portion 10.

FIG. 5 shows a state in which the right side of the housing body 20 is viewed from below, and the electrolyzed water generation unit 7 is omitted.

In the housing body 20, edge surfaces 21 (21A to 21C) having flat portions are formed on the edge portions forming the upper side and the front and rear side sides of the opening portion on the right side. A groove 29 having a width of 0.5 to 2.0 cm is formed inside the edge surface 21, and an inner edge wall 27 having a tip at a position lower (on the left side) than the edge surface 21 is formed inside the groove 29. There is. A sealing material 29A made of an elastic material such as rubber is embedded in the groove 29.

No edge surface is formed on the lower portion of the housing body 20, and it has a plane having a width of 0.5 to 2.0 cm parallel to the edge surface 21 formed at the same position as the right end of the inner edge wall 27. It has a lower flat portion 22 and a back flat portion 23 formed on the left side of the lower flat portion 22 (that is, behind the opening) following the lower flat portion 22. In other words, the lower flat portion 22 extends following the protruding portion 22a that protrudes vertically from the back flat portion 23. Screw fixing portions 24 project from the vicinity of both ends on the front and rear sides of the back flat portion 23.

The edge surface 21, the inner edge wall 27, and the lower flat portion 22 are formed so as to project inward from the housing body 20, and the internal space of the housing body 20 is the edge surface 21, the inner edge wall 27, and the lower flat portion 22. It is formed larger than the opening formed by.

Since the lower flat portion 22 and the back flat portion 23 project upward from the bottom surface 25D, a saucer can be formed together with the front surface 25A and the rear surface 25B, and water leaks from the electrolyzed water generation unit 7. Even in such a case, the leaked water can be retained inside the housing 2.

The edge surface 21 extends downward from the back flat portion 23 to the bottom edge surface 26 (26A and 26B) which is bent and has a plane parallel to the left and right sides. A leg portion 26C made of an elastic body having a low cylindrical shape is attached to the bottom edge surface 26.

The bottom surface 25D extends from the lower side of the back flat portion 23 and is located above the bottom edge surface 26. That is, the bottom edge surface 26 protrudes from the back flat portion 23 and plays the role of a leg that comes into contact with the floor surface when placed.

As shown in FIG. 3, the distance D1 from the lower end 13Ca of the tip of the edge wall 13C in the side panel 3 to the lower side of the edge wall 13D is from the upper end 27Ca of the inner edge wall 27 in the housing body 20 to the lower end of the bottom surface 25D. It is formed so as to be substantially the same as or slightly smaller than the distance D2 (for example, about 0.05 to 1.0 cm). Further, the distance D3 from the lower end 13Ca to the lower end 10Aa of the storage mechanism 10A is formed to be slightly smaller (for example, about 0.05 to 1.0 cm) than the distance D4 from the upper end 27Ca to the upper end 22a of the lower flat portion 22. Has been done.

Therefore, as shown in FIG. 5, when the storage mechanism 10A in the side panel 3 is placed on the lower flat portion 22, the tip portion of the edge wall 13C can be fitted into the groove 29. Since the sealing material 29A is embedded in the groove 29 as described above, the flat portion of the edge wall 13C comes into contact with the sealing material 29A.

At this time, the gap 10D (see FIG. 4) of the filter accommodating portion 10 is fitted into the inner edge wall 27, the protruding portion 10C is fitted into the groove 29, and the recess 13Da formed in the lower edge wall 13D is the screw fixing portion 24. Is designed to avoid.

Although not shown, the same applies in the front-rear direction, and the distance D5 between the insides of the edge walls 13A and 13B is formed to be slightly larger than the distance D6 between the insides of the groove 29 (for example, about 0.05 to 1.0 cm). Has been done. Therefore, the flat portions of the edge walls 13A and 13B come into contact with the sealing material 29A of the groove 29.

That is, since the upper and left and right edge walls 13A to 13C of the side panel 3 come into contact with the sealing material 29A of the housing body 20, the upper and left and right sides are sealed, and the water splashed from the outside is inside the housing 2. It is possible to prevent invasion of.

As described above, the ventilation port plate 4 is arranged at a position facing the exhaust fan 6. Therefore, when the exhaust fan 6 rotates, a flow is formed in which the gas inside the housing 2 moves outward through the panel hole 31 and the through hole 4B.

At this time, since the ventilation gap 39 is formed between the tip of the edge wall 13D and the right end of the back flat portion 23 and the storage mechanism 10A is provided so as to cover the upper side of the ventilation gap 39, the ventilation gap 39 The gas enters through the filter 11 housed in the storage mechanism 10A.

In this way, the opening is provided only on the lower side, and a guard is provided on the upper part of the opening like a step between the back flat portion 23 and the lower flat portion 22 so as to form a bent air flow. .. As a result, the ventilation gap 39 can prevent the intrusion of water from the outside even though it has an opening.

Further, as shown by a broken line in FIG. 2, the housing 2 has a partition wall 41 that separates the left and right directions inside. A control panel 42 for controlling the electric system is installed in the left chamber on the left side of the partition wall 41. Since the electronic components installed on the control panel 42 are vulnerable to water, the left chamber is also provided with a waterproof mechanism similar to that of the right chamber in which the electrolyzed water generating unit 7 is located. Further, in order to release the heat generated from the control panel 42, an exhaust fan 43 and a ventilation mechanism are also provided in the left chamber.

Although not shown, a part of the control panel 42 is electrically connected to the electrolyzed water generating unit 7 on the right side by a wire, and the control panel is formed by passing the wiring through the through hole formed in the partition wall 41. The 42 and the electrolyzed water generation unit 7 are connected.

Although the circumference of the through hole is sealed, it is not fixed in anticipation of replacement of wiring, so the airtightness is not so high. If the pressure in the right chamber is higher than that in the left chamber, the chlorine gas generated from the electrolyzed water generation unit 7 may move to the left chamber.

Therefore, in the electrolyzed water generator 1, the displacement of the exhaust fan 6 in the right chamber is adjusted to be larger than the displacement of the exhaust fan 43 in the left chamber. Specifically, the exhaust amount is made different by installing the exhaust fan 6 and the exhaust fan 43 having different specifications or adjusting the power to be supplied.

As a result, in the electrolyzed water generator 1, the left chamber has a more negative pressure than the right chamber. Therefore, in the electrolyzed water generator 1, even when a pressure difference occurs between the right chamber and the left chamber, the gas can be moved from the left chamber to the right chamber, and the chlorine gas moves to the left chamber. This can be prevented as much as possible.
