Description

  The invention of this application relates to a drain trap. More specifically, the invention of this application relates to a drain trap that can easily suppress the occurrence of slime.

  In drain traps used in kitchens, bathrooms, toilets, washrooms, etc., dirt adheres to the trap body and its surroundings, and microorganisms propagate and so-called slimming occurs. It is considered variously.

For example, it has been proposed to sterilize and wash acid ionic water by spraying acid ionic water to the trap body and its surroundings by utilizing the sterilizing property of acidic ionic water (see, for example, Patent Document 1).

  However, the use of acidic ionized water is premised on the use of an electrolyzer, and there is a problem that it is necessary to provide an electrolyzer separately. In addition, it is necessary to arrange means for ejecting acidic ion water to the trap body and its surroundings, and there is a problem that the structure of the drain trap becomes complicated by the arrangement of the means.

  The invention of this application has been made in view of such circumstances, and an object to be solved is to provide a drain trap that can easily suppress the occurrence of slime.

  In order to solve the above-mentioned problems, the invention of this application first provides a drain trap characterized in that a pair of yin and yang electrodes are disposed in a sealed portion.

  Secondly, the invention of this application provides that in the first drain trap, the cathode is disposed at a portion opened upward to the atmosphere.

  Thirdly, the invention of this application provides that, in the second drain trap, the anode is also disposed at a portion opened upward to the atmosphere.

  According to the first drain trap of the invention of this application, the occurrence of slime is easily suppressed.

  According to the second drain trap of the invention of this application, in addition to the first effect, the gas generated from the cathode can be released to the atmosphere, which is safe.

  According to the third drain trap of the invention of this application, in addition to the second effect, the gas generated from the anode can be released to the atmosphere, and the safety is improved.

  Hereinafter, the drain trap according to the present invention will be described in more detail with reference to the drawings.

  FIG. 1 is a sectional view showing an embodiment of a drain trap according to the invention of this application.

  In the drain trap shown in FIG. 1, a funnel-shaped trap cover (2) is detachably provided on the trap body (1) from above, sealed at the peripheral seal (3), and the lower air leaks upward. Not to be. A filter (4) is attached to the trap cover (2) to prevent objects from falling into the sealed water portion (5) and to cover the sealed water portion (5). A mesh basket (6) is provided on the upper part of the trap body (1) above the trap cover (2).

  And in the drain trap, the electrode part (7) is arrange | positioned at the sealing part (5). The electrode part (7) includes a pair of yin and yang electrodes (8) and (9) as shown in the cross-sectional view of the main part in FIG. In the drainage trap of the invention of this application, as described above, the pair of yin and yang electrodes (8) and (9) are disposed in the sealing portion (5). By applying an electric potential to both electrodes (8) and (9), it is possible to suppress slimming that is likely to occur in the sealed water portion (5) and its periphery. That is, when silver, copper, or the like is used for the anode, silver ions, copper ions, etc. can be eluted in the water in the sealed water portion (5), and sterilization with silver ions, copper ions, etc. becomes possible. Moreover, the propagation of microorganisms can be suppressed by passing a weak current between the electrodes (8) and (9). Furthermore, electrolysis can also be performed. In this case, hypochlorous acid is generated from the chlorine component contained in the water in the sealed water portion (5), and sterilization with hypochlorous acid becomes possible. The electric power supplied to the electrodes (8) and (9) can use, for example, electric power generated in the hydroelectric generator when a hydroelectric generator is provided in the water supply pipe and tap water flows through the water supply pipe by the operation of the curan. .

  Thus, since the drainage trap of the invention of this application is provided with the pair of yin and yang electrodes (8) and (9) in the sealing portion (5), the occurrence of slimming can be easily suppressed.

  In the drainage trap of the invention of this application, as shown in FIG. 3, the cathode (10) can be arranged at a portion opened upward to the atmosphere. When silver, copper, or the like is used for the anode (11), hydrogen gas is generated from the cathode (10). In the drain trap shown in FIG. 3, the hydrogen gas generated at the cathode (10) can be extracted to the atmosphere, and it is safe because it does not collect in the sealed water portion (5). Note that the amount of hydrogen gas generated is very small, and opening to the atmosphere is safe.

  Moreover, in the drain trap of the invention of this application, as shown in FIG. 4, the anode (11) can also be disposed at a portion that is open upward to the atmosphere. When the chlorine component contained in the water in the sealed water portion (5) is electrolyzed and hypochlorous acid is generated and sterilized, chlorine gas is generated from the anode (11). In the drain trap shown in FIG. 4, since the anode (11) is disposed at a position where the anode (11) is opened upward to the atmosphere, the chlorine gas generated by electrolysis escapes to the atmosphere, and the inside of the sealed water (5) Don't get stuck in. As a matter of course, when silver, copper, or the like is used for the anode (11), the cathode (10) is disposed at a portion opened upward to the atmosphere, and thus generated at the cathode (10). Hydrogen gas can be extracted into the atmosphere. In this way, the drain trap shown in FIG. 4 is more secure.

  In the drain trap of the invention of this application, the trap system is not limited to the above embodiment.

  For example, as shown in FIG. 5, the trap (12) may be a trap trap disposed in the trap body (1). In the drainage trap of the invention of this application, even in the trapezoidal trap as shown in FIG. 5, the cathode (10) is arranged in a portion opened to the atmosphere upward, as shown in FIG. The anode (11) can also be arranged at a part opened upward to the atmosphere.

  As a trap system, an S-type trap as shown in FIG. 7 can be used. In the drainage trap of the invention of this application, even in the case of the S-type trap, the cathode (10) is arranged in a portion opened upward to the atmosphere, or the anode (11) is disposed as shown in FIG. Also, it can be arranged at a part opened to the atmosphere upward.

  As described above in detail, the invention of this application can easily suppress the occurrence of slime in the drain trap.
