  The washing tank 1 is provided with a drainage pump 9 for discharging washing water to the outside of the machine at the outer bottom, taking in the outside air into the washing tank 1 on the front side and letting the air in the washing tank 1 out of the machine through the exhaust port 11. A blower fan 10 is provided for discharging. In addition, the heater 7, the cleaning pump 8, the drainage pump 9, the blower fan 10, the atomization generator 12, and the like are controlled to execute each process such as a cleaning process, a rinsing process, a water atomization process, and a drying process. A control device 13 is provided.

  In addition, an atomization generator 12 is provided at the front bottom of the cleaning tank 1 to atomize cleaning water containing high-concentration detergent liquid stored in the cleaning tank 1 or water into fine particles and scatter it into the cleaning tank 1. It has been.

  The configuration around the atomization generator 12 will be described in detail with reference to FIG. The cleaning tank 1 is provided with an opening 1 a for attaching the ultrasonic vibrator 21 to the bottom of the front, and the ultrasonic vibrator 21 is made to face the opening 1 a from the lower outside of the cleaning tank 1 through the waterproof packing 22. It is configured to be attached.

  Further, the periphery of the vibration surface of the ultrasonic vibrator 21 exposed in the cleaning tank 1 is covered with a detergent container 23 so that the vibration surface of the ultrasonic vibrator 21 is directly touched or chopsticks, forks, etc. are in contact with it. Protected against damage. In the upper part of the detergent container 23 and immediately above the vibration surface of the ultrasonic vibrator 21, there is provided a detergent inlet 24 that is opened in a lattice shape and into which the detergent is introduced. An inflow portion 25 through which a certain amount of the cleaning water in 1 flows is provided.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated. When the tableware 5 is set in the table basket 6 from the opening 2 of the washing tank 1 and the detergent is put into the detergent inlet 24 of the detergent container 23 to start the operation, first, water is supplied into the washing tank 1, When the predetermined water level is reached, the water supply is stopped, and when a predetermined amount of water is stored in the cleaning tank 1, a cleaning process is executed.

  The cleaning water in the cleaning tank 1 is heated by the heater 7, pressurized by the cleaning pump 8, sent to the cleaning nozzle 4, and sprayed from the cleaning nozzle 4 toward the dishes 5. The sprayed cleaning water circulates along a path that returns to the cleaning tank 1 after cleaning the dishes 5. This operation is performed for a predetermined time to complete the cleaning process. When the washing process is completed, the drainage pump 9 is energized and the washing water is discharged out of the machine.

  Next, cleaning water is newly supplied, and a rinsing process is performed in which the dishes 5 are rinsed by the same operation as the cleaning process. After rinsing with cold water and draining are repeated about three times, heating and rinsing are performed while energizing the heater 7 to complete the rinsing process.

  When the rinsing process is completed, the water atomization process is performed before the process proceeds to the drying process.

  When this water atomization process is completed, the drainage pump 9 is energized and the rinse water is discharged outside the apparatus. In addition, even if the rinse water is discharged before the start of the water atomization process, and the water atomization process is performed by supplying new washing water, the effect of the above rinse water atomization can be obtained, but after the heating rinse If the washing water is heated, the atomization temperature is higher, which makes it easier to atomize and a greater effect can be obtained.In addition, the effect of the subsequent drying process can be improved, and the time of the drying process can be increased. It can be shortened.

  Next, the heater 7 is intermittently energized while the blower fan 10 is operated, and air containing moisture in the washing tank 1 is discharged from the exhaust port 11 to the outside of the apparatus, and the dishes 5 are dried to complete the dishwashing.

(Embodiment 2)
In the present invention, the control device 13 is configured such that the high-concentration detergent liquid atomization process by the atomization generator 12 is performed prior to the cleaning process. Other configurations are the same as those of the first embodiment, and detailed description thereof is omitted.

  About the dishwasher comprised as mentioned above, the operation | movement and an effect | action are demonstrated. In the present embodiment, the high-concentration detergent liquid atomization process by the atomization generator 12 including the ultrasonic transducer 21 is performed prior to the cleaning process. When the tableware 5 is set in the table basket 6 from the opening 2 of the washing tank 1 and the detergent is put into the detergent inlet 24 of the detergent container 23 to start the operation, first, water is supplied into the washing tank 1, When the predetermined water level is reached, the water supply stops and a predetermined amount of water is stored in the cleaning tank 1. At this time, a certain amount of the stored water flows from the inflow part 25 of the detergent container 23, dissolves the detergent introduced from the detergent inlet 24, and generates a high-concentration detergent solution.

Next, the atomization generator 12 is energized, the ultrasonic vibrator 21 vibrates, and the high-concentration detergent solution in which the detergent is dissolved in the nearby washing water is atomized and scattered as fine particles (mist) for cleaning. The tank 1 is fully filled. All tableware 5 is left in this state for a predetermined time.
A high-concentration detergent liquid mist is attached to the surface of the plate, and the dirt attached to the surface of the tableware 5 is chemically decomposed and swollen so that the surface of the tableware 5 is easily peeled off.

  At this time, the cleaning pump 8 is not driven, and cleaning water is not ejected from the cleaning nozzle 4. In addition, when the heater 7 is energized, the decomposition and swelling effect on the dirt attached to the surface of the tableware 5 is improved and the washing water can be preheated, so that the effect of the subsequent washing process can be reduced. It can be improved, and the time for the cleaning process can be shortened.

  When the high-concentration detergent liquid atomization process ends, the process proceeds to a cleaning process similar to that of a conventional dishwasher. The cleaning water in the cleaning tank 1 is heated by the heater 7, pressurized by the cleaning pump 8, sent to the cleaning nozzle 4, and sprayed from the cleaning nozzle 4 toward the dishes 5. The sprayed cleaning water circulates along a path that returns to the cleaning tank 1 after cleaning the dishes 5. This operation is performed for a predetermined time to complete the cleaning process. When the washing process is completed, the drainage pump 9 is energized and the washing water is discharged out of the machine.

  Next, cleaning water is newly supplied, and a rinsing process is performed in which the dishes 5 are rinsed by the same operation as the cleaning process. After rinsing with cold water and draining are repeated about three times, heating and rinsing are performed while energizing the heater 7 to complete the rinsing process.

  When the rinsing process is completed, the water atomization process is performed before the process proceeds to the drying process. In this water atomization process, the atomization generator 12 provided at the bottom of the cleaning tank 1 operates to atomize the rinse water by the ultrasonic vibrator 21 and attach it to the surface of the tableware 5.

  By performing this water atomization process, as shown in FIG.3 (b), the fog which is a fine particle adheres to the whole surface of the tableware 5, and the weight of a water droplet is increased, or water droplets are As a result, it drops and spreads, and as a result, large round water droplets are reduced. In this way, the mist generated in the water atomization process wets the entire surface of the tableware 5 and reduces large water droplets with high grains, so that the tableware 5 can be easily dried during the subsequent drying process. It is also possible to make it difficult for water drops to stick.

  Further, the vibration surface of the ultrasonic vibrator 21 of the atomization generator 12 is exposed in the cleaning tank 1, and the detergent inlet 24 of the detergent container 23 is used to secure the concentration in the high-concentration detergent liquid atomization process. Since the detergent is likely to be deposited or adhered to the vibration surface of the vibration surface, the atomization performance may be deteriorated or the ultrasonic transducer 21 may be damaged due to self-heating in the worst case. There is. However, by performing this water atomization process, the ultrasonic vibrator 21 can be vibrated while being immersed in cleaning water that does not contain detergent, so that the detergent components deposited and adhered can be removed from the vibration surface. It is possible to always keep the stabilization performance in a stable and best state and to prevent the ultrasonic transducer 21 from being damaged.

  When this water atomization process is completed, the drainage pump 9 is energized and the rinse water is discharged outside the apparatus. In addition, even if the rinse water is discharged before the start of the water atomization process, and the water atomization process is performed by supplying new washing water, the effect of the above rinse water atomization can be obtained, but after the heating rinse When the washing water is heated, the temperature of the atomized water is high, so that it is easy to atomize, and a greater effect is obtained in terms of improving the drying efficiency and finish of the tableware 5, and the drying process performed thereafter The effect of this can be improved, and the time of a drying process can be shortened.

  Next, the heater 7 is intermittently energized while the blower fan 10 is operated, and air containing moisture in the washing tank 1 is discharged from the exhaust port 11 to the outside of the apparatus, and the dishes 5 are dried to complete the dishwashing.

  As described above, the dishwasher according to the present invention reduces the height of water droplets adhering to the surface of the tableware when entering the drying process safely without consuming a large amount of energy. In addition, the surface finish of glass tableware and the like can be improved, so that it is useful as a dishwasher having a drying function.
