<Embodiment>
In FIG. 1, 1 indicates an electrolyzed water generator as a whole. The electrolyzed water generator 1 is assumed to be used in factories that use water. Therefore, the housing 2 has a waterproof specification so that water does not enter the inside of the housing 2 even when water is splashed from above or from the horizontal direction.

The electrolyzed water generator 1 has a rectangular parallelepiped shape, and houses an electrolyzed water generator 7 (see FIG. 2) and exhaust fans 6 and 43 inside a 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 electrolyzed water generating unit 7 electrolyzes raw water supplied from the outside (for example, tap water, industrial water, filtered water, etc.) and an electrolyte aqueous solution in which electrolytes such as salt, sodium carbonate, and hydrochloric acid are dissolved, and electrolyzes. Water (for example, acidic electrolyzed water or alkaline electrolyzed water, or acidic electrolyzed water and alkaline electrolyzed water) is produced. Raw water and 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 the raw water and the aqueous electrolyte solution are provided at the tip positions of the hoses.

As shown in FIG. 2 , the housing 2 is configured such that the left and right side panels 3 can be removed from the housing body 20 . The housing body 20 is composed of four surfaces, a front surface 25A, a rear rear surface 25B, an upper ceiling surface 25C, a lower bottom surface 25D, and left and right openings.

FIG. 3 shows a sectional view near the center of the right side panel 3 and the housing body 20 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 ventilation port plate 4 that is one size larger than the panel hole 31 and elongated on the left and right sides is positioned facing the exhaust fan 6 on the outside of the panel hole 31 provided in the side panel 3 (on the right side in the drawing). It is attached. The vent plate 4 is provided with a through hole 4B and a hood 4A projecting so as to cover the through hole 4B.

The hood 4A extends from just above the through hole 4B to below 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 is open at the lower side, so that even if water is splashed from above or from the horizontal direction, it will not enter the housing 2 through the through hole 4B. It can prevent water from entering.

A filter 5 is attached inside the panel hole 31 of the side panel 3 . As a result, foreign matter can be prevented from entering from the outside of the electrolyzed water generator 1 through the through holes 4B.

FIG. 4 shows the inside (left side) of the right side panel 3 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 according to the operation from the side of the outer surface 3A of the side panel 3 .

The side panel 3 has edge walls 13 (an upper edge wall 13C, a lower edge wall 13D, a front edge wall 13A, and a rear edge wall 13B) whose four sides, which are the ends thereof, protrude from the inner side surface 3B. formed. The height of protrusion is the same on all four sides, and is, for example, about 0.5 to 2.0 cm. The edge wall 13C, the edge wall 13A, and the edge wall 13B on the upper and front sides have flat portions 13Ab to 13Cb that are horizontal to the inner 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. As shown in FIG.

The edge wall 13D on the lower side has a plate-like shape that stands substantially upright from the inner surface 3B, and does not have a flat portion. The edge wall 13D is provided with recesses 13Da in the vicinity of both ends thereof as if the wall were notched.

At a position about 1 to 5 cm above the lower edge wall 13D, a filter housing portion 10 is formed upright from the inner surface 3B. The filter housing portion 10 is elongated in the left and right sides and has a prismatic shape with surfaces on the upper and lower sides. The filter housing portion 10 is formed in a lattice shape consisting of only a hollow frame, and the filter 11 is housed therein. The filter housing portion 10 is composed of a housing mechanism 10A, which is a lattice-shaped projecting portion, and a plate-shaped mounting portion 10B (see FIG. 3). is fixed to

Elongated protruding portions 10C are provided on both front and rear ends of the filter housing portion 10 across a gap 10D. That is, a gap 10D, which is a concave portion, is formed at the end of the filter housing portion 10. As shown in FIG. The projecting portion 10C is formed to be shorter than the length of the filter housing portion 10. As shown in FIG.

FIG. 5 shows the right side of the housing body 20 viewed from below, and the electrolyzed water generator 7 is omitted.

Edge surfaces 21 (21A to 21C) having flat portions are formed on the edge portions forming the upper side and the front and rear sides of the right opening portion of the housing body 20. As shown in FIG. 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 (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. As shown in FIG.

No edge surface is formed on the lower part of the housing body 20, and it has a flat surface with 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 rear flat portion 23 which is formed to the left of the lower flat portion 22 (that is, to the rear of the opening) following the lower flat portion 22 . In other words, the lower flat portion 22 is extended following the projecting portion 22a projecting vertically from the inner flat portion 23. As shown in FIG. Screw fixing portions 24 protrude in the vicinity of both front and rear ends of the inner flat portion 23 .

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

Since the lower flat portion 22 and the inner flat portion 23 protrude upward from the bottom surface 25D, the front surface 25A and the rear surface 25B can form a receptacle. Even if the case is closed, the leaked water can be kept inside the housing 2 .

The edge surface 21 protrudes downward from the inner flat portion 23 and is bent to extend to bottom edge surfaces 26 (26A and 26B) having planes parallel to the left and right sides. A leg portion 26</b>C made of an elastic body having a low columnar shape is attached to the bottom edge surface 26 .

The bottom surface 25</b>D extends from the lower side of the inner flat portion 23 and is positioned above the bottom edge surface 26 . That is, the bottom edge surface 26 protrudes from the inner flat portion 23 and serves as a leg that contacts the floor surface when placed.

As shown in FIG. 3, the distance D1 from the lower end 13Ca of the edge wall 13C in the side panel 3 to the lower side of the edge wall 13D is the distance D1 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. The distance D2 is approximately equal to or slightly smaller (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 slightly smaller than the distance D4 from the upper end 27Ca to the upper end 22a of the lower flat portion 22 (for example, about 0.05 to 1.0 cm). It is

Therefore, as shown in FIG. 5, when the storage mechanism 10A of 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. As shown in FIG. Since the sealing material 29A is embedded in the groove 29 as described above, the flat portion of the edge wall 13C contacts the sealing material 29A.

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

Although not shown, the same applies in the front-rear direction, and the distance D5 between the inner sides of the edge walls 13A and 13B is slightly larger than the distance D6 between the inner sides of the groove 29 (for example, about 0.05 to 1.0 cm). It is Therefore, the flat portions of the edge walls 13A and 13B abut against the sealing material 29A of the groove 29. As shown in FIG.

That is, since the edge walls 13A to 13C on the upper side and the left and right sides of the side panel 3 abut against the sealing material 29A of the housing body 20, the upper side and the left and right sides are sealed, and water splashed from the outside is prevented from entering the housing 2. can be prevented from entering the

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, a 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. , gas enters through the filter 11 housed in the housing mechanism 10A.

In this way, the opening is provided only on the lower side, and a guard is provided above the opening like a step between the inner flat portion 23 and the lower flat portion 22 to form a bending air flow. . As a result, although the ventilation gap 39 has an opening, it is possible to prevent water from entering from the outside.

Further, as indicated by broken lines in FIG. 2, the housing 2 has a partition wall 41 that separates the left and right sides. 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 in the control panel 42 are vulnerable to water, the left compartment is provided with a waterproof mechanism similar to the right compartment where the electrolyzed water generator 7 is located. In addition, an exhaust fan 43 and a ventilation mechanism are provided in the left chamber in order to release heat generated from the control panel 42 .

Although not shown, a part of the control panel 42 is electrically connected to the electrolyzed water generator 7 on the right side by wire. 42 and the electrolyzed water generator 7 are connected.

Although the perimeter of the through-hole is sealed, it is not affixed in anticipation of wiring replacement and the like, so the sealing performance is not very high. If the pressure in the right chamber becomes higher than that in the left chamber, chlorine gas generated from the electrolyzed water generator 7 may move to the left chamber.

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

As a result, in the electrolyzed water generator 1, the pressure in the left chamber becomes more positive than that in the right chamber. Therefore, in the electrolyzed water generator 1, even if there is an air pressure difference between the right and left chambers, the gas can move from the left chamber to the right chamber, and the chlorine gas moves to the left chamber. can be prevented as much as possible.
