Problems solved by technology

Chinese patent ZL 86104026 The preparation method of solid anti-scaling and deodorant for urinal discloses a urine scale cleaning agent of organic polymer, but this urine scale cleaning agent will cause secondary pollution to water sources
Chinese patent ZL 88105809.2 toilet deodorant uses adsorption to deodorize and cannot completely remove urine scale on the urinal
Chinese patent ZL 91106642.x toilet deodorant is also a composition with surfactants, which will cause secondary pollution to water sources after cleaning
However, sodium hypochlorite is extremely unstable in the air and is easily hydrolyzed, so it cannot effectively maintain the sterilization effect for a long time

Embodiment 1

[0020] Methods for electrochemical cleaning of urine scale, such as figure 1 As shown, an electrolytic cell 2 is set in the flushing water tank 1, the volume of the flushing water tank is 18L, and the volume of the electrolytic cell is 500mL; 3 synchronous water injection; after the water in the toilet flushing tank 1 is full, the power controller 6 controls the screw meter 5 in the electrolytic cell 2 to automatically add 15g of sodium chloride to the tubular cathode 7. The power controller 6 discharges the anode 8 and the tubular cathode 7 in the electrolytic cell 2, and electrolyzes for 15 minutes to produce a sodium hypochlorite solution with a concentration of 6g / L; when the flushing water tank 1 releases water through the drain valve to flush the toilet, the water level drops to the flushing water tank When 1 / 8 of the volume, the sodium hypochlorite solution in the electrolytic cell 2 enters the toilet flushing tank through the one-way water outlet valve 4, and flushes t...

Embodiment 2

[0023] Methods for electrochemical cleaning of urine scale, such as figure 1 As shown, an electrolytic cell 2 is set in the flushing water tank 1, the volume of the flushing water tank is 150L, ​​and the volume of the electrolytic cell is 1.5L; The valve 3 injects water synchronously; after the water in the toilet flushing tank 1 is full, the power controller 6 controls the screw meter 5 in the electrolytic cell 2 to automatically add 45g of sodium chloride into the tubular cathode 7 . The power controller 6 discharges the anode 8 and the tubular cathode 7 in the electrolytic cell 2, and electrolyzes for 25 minutes to produce a sodium hypochlorite solution with a concentration of 10g / L; when the flushing tank 1 is flushed through the drain valve, the water level drops to the flushing tank When 1 / 8 of the volume, the sodium hypochlorite solution in the electrolytic cell 2 enters the toilet flushing tank through the one-way water outlet valve 4, and flushes the toilet together w...

Abstract

The invention relates to a method for cleaning urine scale electrochemically. The inside of a toilet washing water tank is provided with an electrolytic cell; the volume of the electrolytic cell is between 1 / 36 and 1 / 100 of the volume of the toilet washing water tank; when water is injected to the toilet washing water tank, water is synchronously injected to the electrolytic cell; after water in the toilet washing water tank is positioned in a full level, NaCl with certain amount is automatically added to the electrolytic cell and is electrolyzed for 15 to 25 minutes to form a NaCIO solution with concentration of between 6 and 10 g / L; when water in the toilet washing water tank is discharged and the water level is reduced to 1 / 8 of the volume of the toilet washing water tank, the NaCIO solution in the electrolytic cell enters the toilet washing water tank and washes a toilet together with residual toilet washing water. The invention also relates to a device for cleaning the urine scale electrochemically; the device comprises a toilet washing water tank; the inside of the toilet washing water tank is provided with an electrolytic cell; and the electrolytic cell comprises a tubularshell, a power controller, a tubular cathode, an anode and a NaCl metering device. The device has the advantages that the device has environmental protection and no pollution, can automatically cleanthe wall of the toilet and can effectively sterilize and deodorize.

Description

technical field [0001] The invention relates to the technical field of sanitary ware, in particular to a method for electrochemically cleaning urine scale and a device for electrochemically cleaning urine scale. Background technique [0002] As we all know, if the bathroom urinal is not cleaned in time, yellow urine scale will be produced. Urine scale mainly contains calcium carbonate, calcium phosphate and other inorganic salts, and about 10% organic matter. Bacterial growth in urinal water is the main cause of urine scale. Under the action of microorganisms, the decomposition reaction of urine scale is as follows: [0003] CO(NH 2 ) 2 +H 2 O=2NH 3 +CO 2 (1) [0004] NH 3 +H 2 O=NH 4 + +OH - (2) [0005] CO produced by the decomposition reaction 2 And part of the ammonia will be released into the atmosphere to produce a bad smell, and the remaining ammonia will be hydrolyzed into NH 4 + and OH - . Oh - The pH value is raised, causing carbona...
