[0010]
FIG. 1 is a configuration diagram of a sterilization apparatus according to a first embodiment of the present invention, and FIG. 2 is a schematic view when the sterilization apparatus is used for sterilization of a kitchen sink.
[0011]
1 and 2, reference numeral 8 denotes a sterilizer, which includes an electrolytic cell 11 as an electrolysis unit provided with electrodes 9 and 10 and a chlorine supply unit for supplying chlorine ions to the electrolytic cell 11, in this embodiment A salt tank 12 storing salt water, a salt flow path 13 connecting the salt tank 12 and the electrolytic cell 11, and a salt pump 14 for feeding the salt solution to the electrolytic cell 11 through the salt flow path 13. Moreover, it has the valve | bulb 16 which controls the flow path 15 of the tap water connected to the water supply pipe indirectly or directly as a conveyance means, and the inflow / outflow of tap water. The foreign matter removing means includes a detergent tank 17 in which neutral detergent for kitchen is stored as a surfactant, and a detergent channel 18 connecting the detergent tank 17 and the channel 15. The detergent channel 18 A detergent pump 19 for feeding a kitchen neutral detergent in a detergent tank 17 as a surfactant tank into the flow path 15 is disposed above. The electrolyzed water generated in the electrolytic cell 11 is discharged from the end portion 20 of the flow path 15. The electrolytic cell 11 and the flow channel 15 are connected via the flow channels 21 and 22. By opening the valve 16, tap water passes from the flow channel 15 through the flow channel 21 and enters the electrolytic cell 11. A water circuit entering the flow path 15 again through the path 22 is formed.
[0012]
Furthermore, the energization of the electrodes 9 and 10 in the electrolytic cell 11 and the operation control of the valve 16, the salt pump 14 and the detergent pump 19 are performed by a control device 23 as a control means.
[0013]
FIG. 2 is a view showing an arrangement example in which the sterilizer 8 is installed on the sink 24. The sink 24 includes a sink portion 25, a work top portion 26, and a currant 27. The sink portion 25 includes a drain outlet. 28, a trap portion 29 at the drain port 28, a basket 30 for receiving garbage etc. is provided in the trap portion 29, and a drainage channel 31 is connected to the lower side of the trap portion 29. These are called the drainage part 32.
[0014]
Next, the operation and action will be described. First, before sterilizing, deodorizing, and removing foreign matter from the drainage section 32 (the sink outlet 28, the basket 30, the trap 29, the drainage channel 31), the valve 16 is opened by the control device 23, and tap water is supplied into the sterilization device 8. Then, tap water is injected into the electrolytic cell 11 through the flow path 15 and the flow path 21. After a predetermined time in the control device 23 has elapsed, the valve 16 is closed, the salt pump is started, and the salt water in the salt tank 12 is passed through the salt flow path 13 by the salt pump 14 so that the chlorine ion concentration in the electrolytic cell 11 is a predetermined concentration. Send in to become. Thereafter, the electrodes 9 and 10 are energized by the control means 23, and electrolyzed water containing an oxidizing substance such as a hypochlorous acid compound is generated in the electrolytic cell 11 by electrolysis.
[0015]
At this time, the electrodes 9 and 10 are periodically switched in polarity to prevent the scale components from adhering to the surfaces of the electrodes 9 and 10. If the electrodes 9 and 10 are energized for a predetermined time and electrolyzed water having a sufficient concentration can be generated in the electrolyzer 11, the drainage section 32 can be prepared for sterilization.
[0016]
When sterilizing and deodorizing the drain port 28, the control device 23 opens the valve 16 and feeds tap water into the electrolytic cell 11 through the flow path 15 and the flow path 21. The electrolyzed water generated in the electrolytic cell 11 through the tap water is sent again from the flow path 22 to the flow path 15, mixed with the tap water that has passed through the flow path 15, discharged from the flow path end 20, and drained. The unit 32 is reached. Discharging electrolyzed water from the channel end 20 and bringing the electrolyzed water into contact with raw waste such as leftovers, leftovers, etc. on the surface of the drain port 28, trap 29, drainage channel 31, and the basket 30. Therefore, it is possible to sterilize microorganisms such as bacteria and mold that propagate on these. Therefore, generation | occurrence | production of odor and reproduction | regeneration of a slime (biofilm) by propagation of microorganisms can be suppressed.
[0017]
However, there are cases where fats and oils components are contained in the raw garbage, or wastewater flowing into the sink 25 is mixed with oils and fats components such as dressing and cooking oil. In such a case, when the electrolyzed water and the wastewater are mixed, it reacts with the alkali or hypochlorous acid compound in the electrolyzed water, and it becomes an environment where saponification is easily generated. White foreign matters are generated all over the portion 32. Moreover, without reacting with the electrolytic water, the trap 29 together when the amount of oil is large time, the basket 30, gradually solidified occurs in discharge water channel 31 or the like, and at the same time disfiguring, these portions Many people feel uncomfortable to touch and feel uncomfortable. If this phenomenon further proceeds, the drainage channel 31 may be clogged.
[0018]
Then, after processing with electrolyzed water, the detergent pump 19 is operated, a predetermined amount of neutral detergent is sent to the flow path 15, discharged from the flow path end 20 through the tap water, and brought into contact with the drainage section 32. By this operation, the oil and fat component adhering to the drainage portion 32 reacts with the alkaline component and hypochlorous acid compound in the electrolyzed water, and the oil and fat component can be removed before adhering to the drainage portion 32 as a white foreign matter. The drainage channel 31 is not clogged and the user does not feel uncomfortable even when touching this part when cleaning it.
[0019]
In the present embodiment, as the conveying means, the tap water flow path 15 indirectly or directly connected to the water pipe and the valve 16 for controlling the flow of tap water are used. The electrolytic water and the detergent remaining in the flow path 15 after the electrolytic water generated in the flow path 11 is sent to the flow path 15 or after the detergent is sent by the detergent pump 19 are washed away with tap water and do not remain in the flow path 15. The deterioration of the flow path 15 due to the electrolytic water and the detergent can be minimized, and at the same time, the electrolytic water and the detergent are long on the object to be treated (the drain port 28, the trap 29, the basket 30, and the drain path 31 in this embodiment). There is no time remaining, and deterioration of these materials can be minimized.
[0020]
In the present embodiment, the electrodes 9 and 10 of the electrolytic cell 11 are energized, and electrolyzed water is generated by electrolysis. Since electrolyzed water containing a constant concentration of hypochlorous acid compound can always be generated, There is no decrease in concentration due to standing for a long time like a drug, the concentration of the hypochlorous acid compound can be kept constant, and the sterilization and deodorizing performance can be stabilized. However, when the chlorine ion concentration in the raw water to be supplied is low, the concentration of the hypochlorous acid compound that can be generated by electrolysis is low, and sufficient sterilization and deodorizing ability cannot be obtained. A salt tank 12, a salt flow path 13, and a salt pump 14 are provided, and the chlorine ion concentration in the electrolytic cell 11 is set to a certain level or more. Therefore, if the amount of current flowing between the electrodes 9 and 10 is constant, electrolysis can be performed. The generated electrolyzed water concentration can be maintained at a constant concentration, and stable sterilization and deodorizing ability can be obtained.
[0021]
(Example 2)
FIG. 3 shows the second embodiment. The difference from the first embodiment is that a decomposing agent tank 33 for storing an enzyme lipase as an oil decomposing agent for decomposing fats and oils instead of the detergent tank 17, the detergent flow path 18 and the detergent pump 19. , Having a decomposing agent pump 34 and a decomposing agent flow path 35, by decomposing oil and fat by the action of an enzyme, removing oil and fat adhering to the drainage part 32, preventing generation of saponified products and solidification of oil and fat Is where you are.
[0022]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0023]
Next, the operation and action will be described. After the sterilization of the drainage part 32 with electrolyzed water, the decomposing agent pump 34 is started by the control means 23, and the lipase in the decomposing agent tank 33 is sent from the decomposing agent channel 35 to the channel 15. The oil and fat discharged from the flow path end 20 and adhering to the drainage part 32 is removed to prevent generation of saponified products and solidification of the oil and fat. By using an enzyme as a decomposing agent, it is possible to reliably remove oils and fats at the same time as reducing the environmental load compared to the case of using a surfactant. Furthermore, since the enzyme is used, the oil and fat decomposition reaction occurs continuously, so that the oil and fat can be effectively removed.
[0024]
In this example, lipase was used as a decomposing agent, but in addition to an enzyme such as lipase, for example, a weak alkali such as sodium percarbonate or a strong alkali such as sodium hydroxide was used to completely eliminate fat and oil. Can be removed.
[0025]
(Example 3)
Example 3 will be described with reference to FIG. The difference from the first embodiment is that a diaphragm 36 is provided between the electrodes 9 and 10, and a flow path switching valve 39 and flow paths 40, 41 and 42 are provided on the downstream side of the electrolytic cell 11. And it is in the point which produces | generates acidic electrolyzed water with the electrolytic vessel 11, and performs the disinfection and deodorization of the waste_water | drain part 32 using this. That is, the diaphragm 36 having material permeability is disposed between the electrodes 9 and 10. Further, on the upstream side of the electrolytic cell 11, the compartment A formed by the electrode 9 and the diaphragm 36 and the flow path 15 are connected by the flow path 37, while the compartment formed by the electrode 10 and the diaphragm 36. B and the flow path 15 are connected by a flow path 38. Further, on the downstream side of the electrolytic cell 11, a flow path 15A and a flow path switching valve 39 are provided, the compartment A and the flow path switching valve 39 are the flow path 40, and the compartment B and the flow path switching valve. A valve 39 is connected by a flow path 41. In addition, a flow path 42 is connected to the flow path switching valve 39 so that electrolyzed water that is no longer needed outside the sterilizer 8 can be discarded.
[0026]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0027]
Next, the operation and action will be described. By opening the valve 16 by the control means 23, the tap water enters the compartment A and the compartment B in the electrolytic cell 11 through the flow path 15 and the flow paths 37 and 38. . Thereafter, by starting the salt pump 14, the chlorine ion concentration in the compartments A and B is maintained at a constant level. By energizing the electrodes 9 and 10 in this state, the compartment A contains hypochlorous acid compound and electrolyzed water having a pH of 3 or less is generated, the compartment B contains sodium hydroxide, pH 11 or more alkaline water is produced.
[0028]
Next, when sterilizing and deodorizing the drainage section 32, the flow path switching valve 39 is switched, and the electrolyzed water in the compartment A is supplied to the drainage section 32 from the flow path end 15B through the flow path 15A. So that That is, by electrolyzing water containing chlorine ions using the electrode 9 as an anode, electrolyzed water containing a hypochlorous acid compound and hydrochloric acid can be generated in the water of the compartment A, and the pH is 3.0. It becomes the following. When the valve 16 is opened in the same manner as in Example 1 and the electrolyzed water in the compartment A in the electrolytic cell 11 is discharged via tap water and the drainage part 32 is sterilized and deodorized, oil and fat are deposited on the surface of the drainage part 32. Even if a kind adheres, no saponification reaction takes place, and no white foreign matter (solid matter) is produced.
[0029]
However, there is a large amount of oil and fat, and the oil and fat may solidify on the surface of the drainage part 32. Assuming such a case, after supplying the electrolyzed water to the drainage section 32, for example, in the case of Example 1, the valve 16 is opened by the control means 23, and the neutral detergent is sent from the detergent tank 17 by the detergent pump 19, By discharging from the channel end 15B and making contact with the drainage part 32, the oils and fats adhering to the surface can be removed. Therefore, since the appearance is not impaired, the user can comfortably clean the drainage section 32.
[0030]
(Example 4 )
Figure 4 shows the sterilizing apparatus according to a fourth embodiment of the present invention. The fourth embodiment is different from the first embodiment in that a hot water heater 43 capable of supplying hot water is provided on the upstream side of the flow path 15 as hot water supply means.
[0031]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
[0032]
Next, the operation and action will be described. After supplying electrolyzed water from the electrolytic cell 11 to the drainage part 32 to perform sterilization and deodorization, the valve 16 is opened and hot water of a predetermined temperature is supplied from the water heater 43 to the drainage part 32. Oils and fats adhere to the surface of the drainage part 32, but the oils and fats are peeled and removed by the surface-active action of warm water, so that saponified products and solidified products are not generated. Therefore, since the appearance is not impaired, the user can comfortably clean the drainage portion 32. Furthermore, since it is warm water, there is no contamination of organic matter in the wastewater, so there is no environmental impact.
[0033]
In addition, in the present Example, the water temperature of warm water was able to acquire the removal effect of fats and oils by supplying warm water of the temperature range of 40 to 70 degreeC. The higher the temperature of the hot water, the higher the removal effect, and the occurrence of solidification of saponified products and oils and fats was less at 50 ° C. or higher.
[0034]
In Examples 1 to 4 , the conveying means may be arranged so that the substances supplied from the sterilizing means and the foreign substance removing means can be supplied to the sink part, the top plate part, and the cooking utensil storage part of the sink.
[0035]
Moreover, in Example 1-4 , it was set as the structure which supplies electrolyzed water from the upper side of the waste_water | drain part 32, However, Since electrolyzed water and an oil-fat removal substance should just be able to be supplied to the object place, the disinfection and deodorizing of the basket 30 are carried out. If it is desired to carry out locally, the flow path ends 20 to 15B may be connected to the trap 29, or the flow path 15 is branched to eliminate sterilization unevenness, and a plurality of flow path ends 20 to 15B are provided. 29 may be connected.
[0036]
【The invention's effect】
As described above, according to the sterilization apparatus according to claim 1 of the present invention, the growth of microorganisms is suppressed, and at the same time, solidified fats and oils and saponification products adhere to the solid surface, and an oily odor is produced and the appearance is impaired. There is an effect that the clogging of the drainage port can be eliminated . In addition, since the substance supplied from the foreign matter removing means is used as a surfactant, the oils and fats adhering to the solid surface are removed, and the hypochlorite compound or sodium hydroxide generated by electrolysis reacts with the oil on the solid surface. And the solid surface can be kept clean.
