In the washing machine 1, a normal course of washing with tap water and a detergent added as necessary, and a tap water is converted into electrolyzed water by the electrolyzed water generator 5 and then introduced into the washing chamber 3 for washing. It is possible to select and operate any one of the disinfection courses. Hereinafter, the procedure of the disinfection course, which is a feature of the present invention, will be described with reference to the flowchart in FIG.

First, the disinfection course is selected by operating the course selection key 14a. And start key 1
When 4b is operated, the operation start signal reaches the CPU and the operation is started (step S1). In response to the operation start signal, the control unit 13 performs initial operation processing (step S2).
~ 3). In this initial operation process, first, the solenoid valve 82 is opened, the tap water from the water supply channel 4 is supplied to the electrolyzed water generating apparatus 5 through the branch water channel 8, the electrolyzed water generating apparatus 5 is operated, and stored in the tank 50. The obtained water is electrolyzed for a predetermined time, for example, 10 minutes (step S2). After a lapse of a predetermined time, the washing water is decomposed into the strongly acidic water and the strongly alkaline water as described above. Along with this disassembling operation, preliminary cleaning is performed in the cleaning chamber 3. Water supply valve 4 for pre-cleaning
2 is opened, tap water is supplied to the cleaning chamber 3 from the water supply channel 4, and the cleaning mechanism 33 is operated (step S3). This preliminary cleaning is performed during the electrolysis period of the electrolyzed water generator 5.

The cleaning water used in the preliminary cleaning is drained prior to the next sterilization cleaning process, and at this time, the drainage channel sterilization process is performed (step S4). In this, the electromagnetic valve 63 is opened for a predetermined time, a part of the acidic water in the tank 50 is supplied to the cleaning chamber 3 through the water passage 6, and is mixed with the water used for the preliminary cleaning. Then, the cleaning mechanism 33 is operated, for example, for 1 minute, and the water is sufficiently mixed in the cleaning chamber 3. After that, the water is made to flow into the drainage channel 7 by the drainage pump 72. In this way, the washing water used in the preliminary washing is
It is drained after being sterilized with acidic water.

Next, a sterilization cleaning process is performed (step S5). Here, the electromagnetic valve 63 is opened, and all the acidic water remaining in the tank 50 is supplied to the cleaning chamber 3 through the water passage 6. The cleaning mechanism 33 is operated and cleaning with acidic water is performed. At this time, the heater 10 is de-energized and the acidic water is used at room temperature. This is because the disinfection performance of acidic water decreases at high temperatures. After sterilization cleaning, drainage is performed through the drainage channel 7.

Next, a main cleaning process using alkaline water is performed (step S6). In this main cleaning process, the solenoid valve 64 is opened and the tank 5 is transferred to the cleaning chamber 3 through the water passage 6.
Alkaline water in 0 is supplied. The cleaning mechanism 33 is operated, and cleaning with alkaline water is performed. At this time,
It is preferable to operate the heater 10 to raise the temperature of the alkaline water to, for example, 50 ° C. or higher. After the main cleaning process, drainage is performed through the drainage channel 7.

Then, a rinsing process is performed in which rinsing is performed using tap water (step S7). That is, the water supply valve 42 is opened, the tap water is supplied to the predetermined water level in the cleaning chamber 3 through the water supply passage 4, and then the cleaning mechanism 33 is operated. The water temperature at this time may be room temperature,
In the present embodiment, the heater 10 is operated to raise the temperature of the wash water to 50 ° C. or higher, more preferably 70 ° C.
As described above, rinsing is performed. Furthermore, when the water temperature at the time of rinsing is 93 ° C. or higher, it can be surely sterilized at the time of rinsing, so it is also preferable as a washing machine for medical instruments, and should the disinfection performance of acidic water be sufficient. Even if there is a case where it cannot be obtained, it can be sterilized without problems by hot water at 93 ° C or higher. After rinsing, drainage is performed.

Next, a drying process is performed (step S).
8). That is, the heater 10 and the blower fan 11 are operated to dry the object to be washed with warm air for a predetermined time. As described above, according to the present embodiment, the object to be washed is pre-washed by the initial operation process of steps S2 to 3 before washing with the electrolytic water in steps S5 to S6, so that the subsequent step S5 is performed. The cleaning ability when using the electrolyzed water can be increased by 6 to 6. For example, it is possible to enhance the disinfecting effect of the acidic water in the disinfecting cleaning process of step S5.

Further, since the pre-cleaning uses the water from the water supply passage 4, it can be carried out at the same time as the electrolysis of the water by the electrolyzed water generator 5, and as a result, it is possible to prevent the pre-cleaning from taking an extra time. . Further, in the sterilization cleaning process of step S5, since the acidic water is used at room temperature, it is possible to maintain the sterilization effect of the acidic water higher than in the case of heating to high temperature.

Further, the main cleaning process using the alkaline water in step S6 can effectively remove stains such as proteins. Particularly, the main cleaning process is performed in step S3.
Since the dirt has been removed by the preliminary cleaning in step 1 and the disinfection cleaning in step S4 with acid water, the cleaning capacity with alkaline water can be further enhanced. In particular, in the main cleaning treatment, the alkaline water is heated to a temperature higher than room temperature, so that the cleaning ability can be further enhanced. For example, heating to 50 ° C. or higher is more preferable because the cleaning ability for oil components is enhanced.

Further, in the main cleaning process, since the cleaning with the acidic water in step S5 has already been completed, it is not necessary to further perform the cleaning with the acidic water after the main cleaning process. As a result, it is possible to prevent fogging of the glass product after cleaning. This is because when cleaning with acidic water and alkaline water consists of multiple steps, if the last step is cleaning with acidic water, the glass product to be washed may become cloudy. there were. On the other hand, in the present embodiment in which the last step is cleaning with alkaline water, the above-mentioned fogging does not occur.

In addition, since the water used for preliminary cleaning can be sterilized by the acidic water in the cleaning chamber 3 by the drainage canal sterilization treatment in step S4, there is a possibility that the effluent may contain bacteria, and There is no risk that bacteria will adhere to and remain in the drainage channel 7 during drainage. Further, after the sterilization washing in step S5, the above-mentioned fear does not occur due to the sterilization action. As a result, the drainage channel 7 can be reliably kept clean. Therefore, in the conventional dishwasher, an offensive odor may be generated due to the bacteria remaining in the drainage channel, whereas in the washing machine of the present embodiment, such an offensive odor can be prevented. Further, when the washing machine according to the present embodiment is used as a washing machine for washing medical instruments and the like, it is possible to prevent harmful bacteria and the like from being inadvertently discharged outside the machine together with drainage.

Further, since it is only necessary to generate the electrolyzed water during the pre-cleaning, it is possible to allow a certain amount of time for the electrolyzed water to be generated. Can be converted. For example, as the electrolyzed water generator 5, a type that stores water in the tank 50 and electrolyzes can be used, and if this type is used, the structure can be simplified and the voltage applied to the electrodes can be reduced. can do.

In the above-described embodiment, the electrolyzed water producing apparatus 5 electrolyzes the saline solution stored in the tank 50 as an electrolysis tank to obtain electrolyzed water in the tank 50. However, the configuration is not limited to this. For example, the electrolyzed water generator 5 may be any device that stores electrolyzed electrolyzed water in a tank. Further, in the above-described embodiment, the electrolyzed electrolyzed water is used for cleaning with the same concentration, but the present invention is not limited to this. For example, it is possible to generate a thicker amount of electrolyzed water, mix the electrolyzed water with the water from the water supply passage 4, and dilute the electrolyzed water in the cleaning chamber 3 for use. In this case, the capacity of the tank 50 can be reduced.

The cleaning mechanism 33 is, for example, the cleaning chamber 3
It may have an injection port fixed therein, or may have a configuration in which the object to be washed is immersed in the cleaning water stored in the cleaning chamber 3 for cleaning. Any structure may be used as long as it can wash the article to be washed. Further, although the washing machine has been described as an instrument washing machine, it may be configured as a dish washing machine mainly for washing dishes.

Further, the washing machine capable of preventing the glass instruments after washing from being fogged is not limited to the above-mentioned constitution. For example, as described above, a washing machine that operates in the order of preliminary washing, washing with acidic water, washing with alkaline water, and then rinsing may be used. Here, the preliminary washing may be washing with only water, or may be washing with alkaline water, for example. In addition, various design changes can be made without changing the gist of the present invention.
