INSTRUCTIONS: C Technical Fields of the Invention 3 Field of the Invention The present invention relates to a dish washing machine for washing dishes such as dishes. [Prior Art] BACKGROUND OF THE INVENTION A conventional general dish washing machine disclosed in Japanese Laid-Open Patent Publication No. Hei. As shown in Fig. 4, the conventional dishwasher main body 1 is provided with a washing tank 13' inside and supplies cold water or hot water to the washing tank 13 by the water supply valve 3, and in the washing tank I A drain hole 4' is provided at the bottom, and a washing pump 5 that communicates with the drain hole 4 and is driven by a motor (not shown) is attached, and the washing water is circulated inside the washing tank 13 by the washing pump 5. . Further, the drain hole 4 is provided with a filter 6 for collecting the residue (slag). In the above configuration, the washing water supplied into the washing tank 13 is sucked into the washing pump 5 through the residue filter 6, and then supplied to the washing nozzle 7 provided at the bottom of the washing tank 13 by the washing pump 5. Further, the washing water sprayed by the washing nozzle 7 is washed back to the drain hole 4 after washing the laundry 8 such as dishes, and circulates in this path. At this time, the residue or the like washed off by the washed matter 8 flows into the collapse transition device 6 together with the washing water, and is collected by the residual filter 6 without being able to pass through the large volume of the residue filter 6. Further, a heater 9 for heating the washing water is installed between the washing nozzle 7 and the bottom of the washing. A dish blue 1 is placed above the washing nozzle 7, and the dish 10 can arrange the dishes 8 in a neat manner, and the washing water can effectively eject the object 8 to be cleaned, thereby improving the washing action. u receives the 'drainage part of the drainage pump 11: the second clean water discharge machine, the U is driven by the control unit 12, (4) for _, cleaning _ electrical parts. In the conventional structure of the above-mentioned dishwasher, it is not particularly suitable for the direct heating, the cooking of the scorch (for example, milk roast, tea bowl steaming, etc.). As a solution to this problem, the washing water having a high-concentration lotion containing a higher concentration of the lotion used is adhered to the object to be washed, and the pretreatment process is set for a period of time, thereby greatly improving The cleaning performance is based on the fact that the spray generating water containing a high concentration of the lotion is attached to the object to be washed, and the atomizing device is generally used, for example, JP-A-62-138631 A supersonic humidifier disclosed in the publication is a structure in which an ultrasonic vibration element is used to atomize a liquid, and a structure in which an ultrasonic vibration element is attached to a machine is explained by the fifth drawing. In Fig. 5, an opening portion 13a' is provided at the bottom of the storage tank 13 for injecting liquid, and is mounted such that the vibration surface of the ultrasonic vibration element 14 faces the opening portion 13a, and the ultrasonic vibration element 14 is inserted into the assembly. The groove portion 15a provided with the waterproof gasket 15 prevents water from leaking from the inside. Further, the ultrasonic vibration element 14 is generally arranged in a slanted shape instead of a horizontal shape as shown in the figure to ensure its atomization energy. Further, a unit in which the ultrasonic vibration element 14 is mounted on the waterproof gasket 15 is attached to the fixing member 16 and assembled at a predetermined position on the bottom of the washing tank 13. Accordingly, the above-described conventional atomization generating device is used for the meal 6 in the first to third figures, and the dishwasher body 1 is provided with a washing tank 2 for storing the laundry such as tableware. Cold water or hot water is supplied to the cleaning tank 2 through the water supply valve 3, and a drain hole 4 is provided in the bottom of the washing tank 2, and a motor (not shown) is connected to the drain hole 4 and connected thereto. The washing pump 5' is driven to circulate the washing water inside the washing tank 2 by the washing pump 5. Further, the drain hole 4 is provided with a residue filter 6 for collecting the residue. An atomization generating portion 17 is provided in front of the bottom of the washing tank 2 (to the left in Fig. 1). As shown in Fig. 2, the atomization generating unit π is configured such that an opening portion 2b having a hole is formed in the inclined surface 2a provided at the bottom of the inner wall of the front side of the cleaning tank 2, and is inclined here via the waterproof gasket 19. The ultrasonic vibration element 18 for atomizing the washing water supplied to the bottom of the washing tank 2 is attached, and the ultrasonic vibration element 18 is inserted into the groove portion i9a in which the waterproof gasket 19 is provided, thereby preventing water from leaking from the outside. . Further, in order to ensure the atomization efficiency of the ultrasonic vibration element 18 itself, it is inclined so as to be horizontal along the inclined surface 2a. Further, a single cymbal in which the ultrasonic vibration element 18 is assembled to the waterproof gasket 19 is placed in the fixing member 2G, and is attached to a predetermined position outside the bottom of the cleaning tank 2, whereby the assembly can be easily and easily assembled. The waterproof gasket 19 has a tight space to prevent water from leaking out of the opening. As shown in Fig. 2, the vibration surface of the ultrasonic vibration element 18 is in the above-described mounted state. The opening of the 18a with respect to the two opening end edges of the inclined opening portion (the inside of the cleaning tank 2 and the ultrasonic vibration element 18 side in Fig. 2) is inclined at an elevation of π The end periphery (in the second drawing, the inner side of the washing tank 2) is at a position higher than the lowest portion 2c, that is, the center portion 18a is disposed to be inclined so as to be located at the periphery of the inner side of the washing tank 2 of the opening portion The lowest part 2c is higher. In Fig. 2, the center 18a of the ultrasonic vibration element 18 is disposed so that the dimension L' is higher than the lowest portion 2c of the periphery of the opening end of the opening 2b, and the vibration surface of the ultrasonic vibration element 18 is set to be washed. The bottom of the tank 2 faces the inside of the washing tank 2 by the opening portion 2b. In Fig. 2, the opening portion 2b is a hole structure penetrating through the wall surface of the cleaning tank 2. However, the present invention is not limited to such a configuration, and may be a structure in which the inner wall of the cleaning tank 2 is recessed inward to form a concave portion or the like, and the ultrasonic vibration element 18 may be mounted therein, and in this configuration, The members in which the ultrasonic vibration element 18 is disposed in the spacer 19 are all housed in the recess, and it is not necessary to punch a hole in the bottom of the cleaning tank 2. However, the recess provided in the inner wall is equivalent to the first portion. 2 The figure is constructed and defined as the "opening". Next, a cylindrical partition wall 21 is provided on the outer periphery of the opening portion 2b at the bottom of the cleaning tank 2, and the height of the partition wall 21 is higher than the effective washing water level generated by the ultrasonic vibration element 18, and It is preferable that the part of the partition wall is integrally formed with the inner wall of the washing tank 2. Further, a portion of the partition wall 21 is cut, and a communication portion 22' for penetrating the opening portion side of the bottom portion of the cleaning tank and the outer side thereof is provided, and the communication portion 22 is used for supplying water to the inside of the washing tank 2, The water is also immersed in the lotion preparation unit 23 located inside the partition wall 21, and the washing water having a higher concentration of the lotion than the washing water sprayed by the washing nozzle 7 is produced. The dishwasher having the aforementioned configuration describes its function. First, a predetermined amount of the lotion is put into the partition wall 21 of the atomization generating portion 17, and when the operation is started, the control portion 12 opens the water supply valve 3 and supplies a predetermined amount of water. At this time, the control portion 12 controls the water supply. The water level is set higher than the ultrasonic vibration element 18 so that the atomization efficiency of the ultrasonic vibration element 18 is in a good state, and the supplied water is immersed in the partition wall 21 by the communication portion 22, and part of the lotion is dissolved in the washing water. 'The washing liquid preparation unit 23 is made into a high-concentration washing water. Hereinafter, the washing water having a high concentration of the lotion is abbreviated as high-concentration washing water. At this time, when the ultrasonic vibration element 18 is driven, the high-concentration washing water located thereon is vibrated by the vibration, and the high-concentration washing water is atomized, and the lotion stored in the partition wall 21 is also The dissolved high-concentration washing water is scattered in the washing tank 2, and the high-concentration washing water can be attached to the object to be washed 8. If the washing water above the ultrasonic vibration element 18 is used, the atomization is naturally stopped and the concentration washing water does not scatter. Therefore, when the ultrasonic vibration element 18 is driven, the control unit 12 To control the water supply 3, there must be a washing water above the ultrasonic vibration element 18. In this configuration, in fact, since the inside of the cleaning tank 2 and the partition wall 21 are connected by the connection _22, the partition wall The water level inside 21 will not be lowered, and the necessary water level for atomization will be used. Further, by adjusting the area of the communicating portion 22, the detergent can be prevented from diffusing, and an effective high-concentration washing water can be secured. As described above, as a pre-step of the washing step, the high-filling, %-purified water is scattered in the washing tank 2, and the high-concentration washing water is attached to the washed object 8 disposed in the dish blue When it is placed in the state and placed in the state for a certain period of time, the concentration of the washing water adheres to the object to be washed 8, and the scale is chemically decomposed. In the main step after the pre-step, the pre-step is performed by the high-concentration washing water to decompose the specific dirt, and then the conventional dishwashing machine is cleaned for the dirt. The washing water supplied to the washing tank 2 is sucked into the washing pump 5 through the residue transition unit 1353234, and then supplied to the washing nozzle 7 provided in the bottom of the washing tank 2 by the washing pump 5. The washing water sprayed by the washing nozzle 7 is returned to the drain hole 4 after washing the laundry 8 such as dishes, and circulates in this path. At this time, the residue of the washed matter 8 and the like are poured into the 5 residue filter 6' together with the washing water, and the large-volume residue which cannot pass through the residue filter 6 is collected by the residual filter 6. The mechanical force such as the dirt of the object to be cleaned 8, the temperature of the washing water, and the strength of the washing water sprayed by the washing nozzle 7 is quite effective, and the decomposing is not only by the front operation. Therefore, in the same manner, the dirt can be reliably washed by the mechanical force such as the temperature of the washing water by the heater 9 and the jet of water from the washing nozzle 7 caused by the washing pump 5, however, The decomposition of oil caused by the method of leaving a high concentration of washing water after standing for a certain period of time in the pre-step is quite effective for the types of dirt that cannot be removed in the past. 15 Follow the steps of the dishwasher to rinse off The lotion component is finally discharged from the outside of the machine by the drain hole 4 through the drain pipe 11a by the drain pump 11 of the drain portion, and then the drying step is performed. The rinse water at the end of the rinsing step after several rinsings, the temperature of the washing water rises to about 60 to 80 degrees at the final rinsing, and the final washing water will be clean and free of the lotion composition. Further, the state of the periphery of the ultrasonic vibration element 18 will be described. The center 丨 8 a of the ultrasonic vibration element 18 is disposed at a position higher than the peripheral edge of the opening end 2b with respect to the opening end 2b of the inclined opening portion 2b, and therefore, as shown in Fig. 2, Ultrasonic vibration 12 when draining
