Therefore, if you try to suppress the growth of bacteria even if these environments change, it will be the supply condition of sterilizing water that matches the conditions that are most likely to propagate, increasing the chlorine concentration of the sterilizing water more than necessary, or sterilizing. It was necessary to increase the frequency of water supply. For this reason, there is a problem that not only the running cost becomes high, but also contamination of waste water by sterilizing water becomes a problem.

[0032]

The growth characteristics at this time are obtained by setting the level within the range of use with the three factors of the temperature, moisture and the amount of organic matter of the drainage basket 11 as factors. Specifically, the drainage basket 11 is sterilized with electrolyzed water, and the time until the number of bacteria grows to a predetermined number (for example, 10 ³ levels per surface 100 cm ² ) from the time when the number of bacteria dies or is not proliferated is experimentally determined.

[0038]
In general, the growth characteristics of bacteria are classified into a lag phase, a logarithmic growth phase, a stationary phase, and a death phase, as shown in FIG. What is important when performing sterilization in the target region 11 is the time required to shift from the lag phase to the logarithmic growth phase. This lag phase is greatly affected by the stress and nutritional conditions on the bacteria, and changes from a to d in the figure. In the drawing, a indicates a case where the temperature is high and d indicates a low case. In the embodiment, typical influential factors are temperature, moisture, the type and amount of nutrients put into the drainage basket, the concentration and amount of electrolyzed water, and the sterilization time.
[0039]
Next, the operation and operation of this embodiment in the above configuration will be described with reference to FIGS.
[0040]
In FIG. 3, when the operation is started at 60, an environmental condition is input at 61. This is to detect the temperature, moisture, and nutrient substance amount detected by the environment detection means 41 in FIG. 1, and the environmental condition of the drainage basket 11 is detected by the temperature sensor 44, moisture sensor 46, and dirt detection means 48 (photo sensor), respectively. To detect.
[0041]
A growth time determination unit 62 estimates the time required for the bacteria in the drainage basket 11 to reach the predetermined number of bacteria, and calls the growth storage unit 63 for a growth time suitable for the environmental conditions determined in 61.
[0042]
Growth storage unit 63, as described in 42 of Figure 1, four levels of temperature conditions, three levels of moisture conditions, typical growth time under the conditions of 36 patterns that combine three levels their respective stains degree Is remembered. Then, the growth time determination unit 62 calls one growth time from the temperature, moisture and the degree of contamination obtained from the environmental condition input.
[0043]
In 64, the electrolysis start time Td is calculated from the growth time Tz obtained in 62 by the following equation (1).
[0044]
Td = Tz-Ta-Tb (1)
However, Ta is the time required for electrolysis. Tb is a marginal time and is the estimated error of the growth time Tz. Thus, the electrolysis start time Td is obtained by subtracting Ta and Tb from the growth time Tz, thereby speeding up the electrolysis time. Can be suppressed.
[0045]
65 displays on the notification means 50 the remaining time until the sterilization is started (current time-Tz-Tb).
[0046]
66 determines whether the elapsed time from the start has exceeded Td. If it has exceeded, the process proceeds to 67 to start electrolysis, and if not, the process returns to 61.
[0047]
In 67, salt supply operation is performed. Here, the water supply pump 39 shown in FIG. 1 is operated to supply water into the salt tank 37 through the water supply pipe 38, and the internal saturated saline is supplied into the electrolytic cell 14 and collected at the bottom of the electrolytic cell 14.
[0048]
Next, in the electrolytic operation 68, the DC power source 34 is operated, a voltage is applied between the electrodes 21 and 22, and electrolysis is started.
[0049]
Immediately after the start of electrolysis, since most of the electrodes 21 and 22 are in contact with water, electrolysis of water occurs preferentially, and hydrogen and oxygen gas are generated between the electrodes 21 and 22. Since these gases are lighter than tap water, they float on the upper part of the electrolytic cell 14. This gas movement causes an upward flow of water between the electrodes 21 and 22. Then, the salt water staying at the bottom of the electrolytic cell 14 is sucked up between the electrodes 21 and 22 by the flow of water generated by the gas floating, and diffuses into the water in the electrolytic cell 14. In general, it is said that the higher the chlorine ion concentration, the higher the production efficiency of chlorine compounds such as hypochlorous acid (hereinafter referred to as hypochlorous acid), and the following reactions are likely to occur.
[0050]
2Cl ⁻ + 2e ⁻ → Cl ₂ ↑
Cl ₂ + OH ⁻ → HClO + Cl ⁻
Cl2 + 2OH ⁻ → ClO ⁻ + Cl ⁻ + H ₂ O
In addition, when hypochlorous acid is generated by electrolysis, the amount of saline solution supplied greatly affects the generation efficiency of hypochlorous acid. That is, if the amount of salt water supplied to the electrolytic cell 14 increases, the generation efficiency increases, the concentration of hypochlorous acid generated in the electrolytic cell 14 increases, and if the amount of saline supplied is small, hypochlorous acid. Since the acid production concentration is lowered, the saturated saline solution is sent in a fixed amount by the feed water pump 39.
[0051]
Furthermore, if the DC power supply 34 is energized for a certain period of time with a constant current between the electrodes 21 and 22, hypochlorous acid having substantially the same concentration can be generated each time. That is, the production concentration of hypochlorous acid as electrolyzed water is determined by the supply amount of sodium chloride and the energization amounts to the electrodes 21 and 22.
[0052]
When the electrolysis operation is completed, the routine proceeds to 69. Here, the water supply means 26 is opened, water is supplied to the electrolytic cell 14, and high concentration (for example, 2000 ppm) electrolytic water in the electrolytic cell 14 is discharged from the outlet channel 28 to the mixing unit 29. On the other hand, water is supplied from the bypass passage 30 to the mixing means 29, and the mixed and diluted electrolytic water is taken from the electrolytic water supply passage 31.
[0053]
70 predicts the concentration of hypochlorous acid in the electrolytic cell 14 and controls the mixing means 29 so that the concentration from the electrolyzed water supply path 31 becomes a predetermined value.
[0054]
For the concentration prediction of hypochlorous acid in the electrolytic cell, an electrolytic water concentration attenuation characteristic is experimentally obtained in advance and is predicted from the characteristic. Equation (2) shows a characteristic example.
[0055]
X = DE−t−F · Σw (2)
However, X: Hypochlorous acid concentration predicted value D: Hypochlorous acid initial concentration immediately after electrolysis E: Coefficient of elapsed time t: Elapsed time from the end of electrolysis F: Coefficient of water supply Σw: Water supply from the end of electrolysis Accumulated value of amount The electrolyzed water generation concentration which is the hypochlorous acid initial concentration D is determined by the supply amount s of salt and the energization amount q to the electrodes 21 and 22 as described above. Therefore, it is obtained from equation (3).
[0056]
D = G · s · q (3)
However, G: coefficient of salt supply amount and energization amount (function of non-linear salt supply amount s)
When the supply of the electrolyzed water is completed, it is determined at 71 whether the sterilization operation is continued. Here, the determination is made based on the on / off state of an operation switch (not shown) set by the control means 13. When the process ends, the process proceeds to 72 to stop the device. In the case of continuing, at 73, the timer is reset, and the growth time, hypochlorous acid concentration predicted value, etc. are cleared. And it returns to 61.
[0057]
As described above, according to the present embodiment, the bacterial growth time corresponding to the temperature, moisture, and degree of dirt in the drainage basket is obtained, and sterilization is performed with electrolytic water before the growth, so that excessive sterilization can be performed. In addition, the bacterial growth of the drainage basket can be suppressed without much trouble, and no odor or slime will occur.
[0058]
In addition, since the concentration change of the electrolyzed water is predicted and diluted to a predetermined concentration, it is possible to supply a large amount of electrolyzed water having a constant concentration.
[0059]
In this embodiment, the nutrient substance detection means detects the degree of contamination by the dirt detection means, and estimates the amount of nutrient substance of bacteria by the estimation means from the degree of contamination. Instead, the following configuration functions similarly.
[0060]
The nutrient substance detection means detects the usage time from the frequency detection means (not shown) for detecting the usage frequency of the target part 11 from the presence or absence of water flowing in the drainage basket as the target part 11 and the time when the water flows into the drainage basket. Time detection means (not shown), and estimation means (not shown) for estimating the amount of nutrient substances from both the frequency detection means and the time detection means, and the presence or absence of water uses the moisture detection means 47. There is a high correlation between the amount of antibacterial nutrients and the frequency and time of running water because the antibacterial nutrients flow into the drainage basket when washing dishes and foods when working in the kitchen at a general household. The estimation means quantifies this correlation and estimates the amount of nutrients.
[0061]
In addition, in order to identify pollutants that flow into the drainage basket, a pollutant determination means (not shown) that is a switch for designating vegetable scraps, meat fish, leftover food, etc., and a frequency detection means for detecting the pollution frequency of the drainage basket (figure Not shown), time detection means (not shown) for detecting the drainage basket contamination time, and estimation means (not shown) for estimating the amount of nutrient substance from the information of these contaminant determination means, frequency detection means and time detection means In this case, the pollutant can be identified, so that the bacterial growth can be estimated with higher accuracy.
[0062]
(Example 2)
Components having the same structure as the electrolysis apparatus of Example 1 are given the same reference numerals, and description thereof is omitted.
[0063]
The difference from Example 1 is that the growth storage means 80 in FIG. 4 sterilizes the drainage basket with electrolyzed water, and measures and obtains the growth characteristics of the number of bacteria and the elapsed time from that time in advance and stores them. The growth characteristics at this time are the same as in Example 1 except that the three factors of drainage basket temperature, moisture and the amount of organic matter are used as factors, and the level determined within the range of use is used. In Example 1, the drainage basket is sterilized with electrolyzed water, and only the time until the number of bacteria grows to a predetermined number of bacteria (for example, 10 ³ levels per surface 100 cm ² ) from the time when the number of bacteria dies or is not proliferated is tested. In addition to this, in Example 2, it is the point which has the growth rate when bacteria enter into the logarithmic growth phase in the memory value. As with the growth time, the temperature condition is less than 10 ° C., 10-20 ° C., 20-30 ° C., 30 ° C. or higher, and the moisture condition is less than 1%, 1-5%, 5% % Of 3% or more, the degree of contamination detected by the photosensor as the amount of organic matter, 3 levels of small, medium and large, combined with the level of each factor (4 × 3 × 3) in 36 pattern conditions It remembers typical growth rates.
[0064]
In 81, one growth rate is called from the temperature, moisture, and degree of contamination obtained from the environmental condition input 61.
[0065]
In 82 mixing means control, the dilution concentration of the electrolyzed water is determined and controlled according to the growth rate set in 81. Specifically, when the growth rate of bacteria is fast (for example, the number of bacteria doubles within 30 minutes), the concentration of electrolyzed water is increased (for example, hypochlorous acid concentration 500 ppm), and the growth rate is slow (for example, the number of bacteria). Is doubled after 3 hours), the concentration of electrolyzed water is reduced (for example, 50 ppm). If the growth rate is in the meantime (for example, the number of bacteria doubles in 30 minutes to 3 hours), the electrolyzed water concentration is set to the middle (for example, 300 ppm).
[0066]
The growth rate of bacteria increases as environmental conditions improve. This state is generally a condition in which sterilization is not effective. Therefore, in this embodiment, the highly active bacteria are surely sterilized by using electrolyzed water having a higher sterilizing strength, and the bacteria having low activity are sterilized by using electrolyzed water having a low sterilizing strength. The impact on equipment is reduced.
[0067]
In this embodiment, the sterilization strength of the electrolyzed water is changed by diluting the electrolyzed water. However, the electrolysis power, that is, the current value to the electrode and the energizing time may be changed, and the operation amount of the water supply pump 39 may be changed. May be adjusted to adjust the amount of saline solution supplied to the electrolytic cell 14. Moreover, you may change the supply amount and supply time of electrolyzed water.
[0068]
The growth predicting means in Examples 1 and 2 is a growth storage means for sterilizing a drainage basket with electrolyzed water, and measuring and obtaining in advance the growth characteristics of the number of bacteria and the elapsed time from that point, and storing them. It is composed. This growth characteristic may be formulated as a function of temperature, moisture, and degree of soiling, and bacterial growth may be predicted using this formula.
