Description

  The present invention relates to a sterilized deodorant water generating device for mixing two kinds of chemicals and water to produce sterilized deodorized water, and to wash the sterilized deodorized water generated by the sterilized deodorized water generating device. The urinal washing water supply device for supplying to the urinal as a urinal.

  Conventionally, in order to reduce the amount of washing water that flows after the use of the urinal, a water-saving urinal having a usage amount of about 1.2 to 2 liters per time has been developed.

  However, if the amount of washing water used is reduced, for example, bacteria may be generated due to a decrease in the replacement rate of urine and water collected in a trap at the urinal drain (a pool of odors that prevents backflow of odor from the drain pipe). In addition, there is a problem that water saving is limited because there is a problem that the drainage pipe is clogged or odor is generated due to generation of dirt or urine stone that cannot be surely flowed.

  Therefore, chemicals are also used for cleaning urinals. For example, the amount of chemicals from the chemical solution supply unit consisting of the chemical solution container and the supply container and the amount of water from the water supply pipe are adjusted by controlling the on-off valve. A flushing urinal drug solution injection device has been proposed (see Patent Document 1).

  In addition to urinal cleaning applications described above, in each field such as food processing, agricultural livestock, medicine, and environment, hypochlorous acid water is used to produce sterilized deodorized water. Various devices and the like are also used for cleaning (see, for example, Non-Patent Document 1).

The second chemical liquid cylinder 93 passes through the second support hole 30 of the spring receiving portion 27 and also through the second support hole 76 of the chemical liquid cylinder fixing portion 73, and the second chemical liquid cylinder 93 sandwiches the chemical liquid cylinder fixing portion 73. The second chemical liquid cylinder 93 is fixed to the chemical liquid cylinder fixing portion 73 by a pair of nuts 36 that are screwed into the chemical liquid cylinder 93.

  In this way, the first chemical liquid cylinder 91 and the second chemical liquid cylinder 93 are configured so as to be fixed at arbitrary positions in the front-rear direction (left-right direction in FIG. 10), whereby the first chemical liquid cylinder is made per stroke. The amounts of the first chemical liquid and the second chemical liquid supplied from the cylinder 91 and the second chemical liquid cylinder 93 can be finely adjusted.

  In the above-described third embodiment, as in the second embodiment of the present invention, the aspirator 71 is installed only at a position close to the second chemical liquid cylinder 93 and water, the first chemical liquid, However, the invention according to the present embodiment is not limited to this case. For example, as in the first embodiment of the present invention, Needless to say, the present invention can also be applied to the case where an aspirator is installed at a position close to the first chemical liquid cylinder and the second chemical liquid cylinder.

  As described above, according to the sterilizing and deodorizing water generating devices 1, 70, 90 according to the first to third embodiments of the present invention, the three-way solenoid valve 3 is used, so the piping around the hydraulic cylinder 4 Since the number of parts such as the above can be reduced, the entire apparatus can be simplified and the cost can be reduced.

  Moreover, since two types of chemical liquids, the first chemical liquid and the second chemical liquid, are mixed with water, the sterilizing and deodorizing power can be enhanced.

  Further, the gap between the first chemical liquid cylinder 8 and the first chemical liquid cylinder rod 9 and the gap between the second chemical liquid cylinder 13 and the second chemical liquid cylinder rod 14 are used as the pump chamber. Since the chemical solution and the second chemical solution are sent out, a power source such as a pump becomes unnecessary, the apparatus and control can be simplified, and the initial cost and running cost can be reduced.

  In addition, since the first chemical solution container 6 and the second chemical solution container 11 are accommodated integrally in the case 50, the replacement work of the first chemical solution and the second chemical solution can be simplified.

  Next, referring to FIG. 11 and FIG. 12, the sterilized deodorized water generated by the sterilized deodorized water generating devices 1, 70, 90 according to the first to third embodiments described above is small as cleaning water. A toilet flushing water supply device for supplying to a toilet will be described. Here, FIG. 11 is a front view showing the flush water supply device for urinals, and FIG. 12 is a side view showing the flush water supply device for urinals.

  The urinal washing water supply device includes a spray washing nozzle 102 attached to the upper part of the urinal 101. This spray cleaning nozzle 102 is connected to, for example, the sterilizing / deodorizing water supply facility 16 shown in FIG. 1 and, as shown by broken lines in FIGS. It is comprised so that water can be injected.

  By spraying the sterilizing and deodorizing water in such a three-dimensional radial manner, it is possible to sterilize and deodorize more urinal inner surfaces with a smaller amount of water compared to the spreader cleaning method which is a conventional urinal cleaning method. In addition, since the floor around the urinal 101 can be sterilized and deodorized, the urinal and the toilet where the urinal is installed can be kept hygienic.

  In the first to third embodiments described above, by using a gear mechanism (not shown) such as a rack and pinion, the linear reciprocating motion of the piston rod 31 is converted into a rotational motion, and the piston rod 31 is used. You may comprise so that it may generate electric power by linear reciprocating motion. In this case, when there is a power generation amount that is greater than or equal to the power generation amount consumed by the sterilizing and deodorizing water generating devices 1, 70, 90, it is possible to store electricity and to eliminate power supply.

  In the first to third embodiments described above, a gap between the first chemical liquid cylinder and the first chemical liquid cylinder rod and a gap between the second chemical liquid cylinder and the second chemical liquid cylinder rod. As the pump chamber, the first chemical solution and the second chemical solution are sent out, but it is also possible to send out the first chemical solution and the second chemical solution using a commercially available rotary micro metering pump. is there.
