Embodiment 1

[0055] figure 1 It is a schematic sectional view of a dishwasher provided with a cleaning device in the first embodiment of the present invention, figure 2 A cross-sectional view of its key parts, image 3 A top view of this key part. As shown in these drawings, a washing tank 22 is provided in the body 20 of the dish washing machine, and the washing tank 22 can be opened / closed through a machine door 21, and the objects to be cleaned 23 such as tableware are first placed in the tableware basket 24, and then Put it in the cleaning tank 22. The water inlet valve 25 is used for supplying washing water into the washing tank 22 . The washing pump 26 pressurizes the washing water and supplies it to the plurality of injection holes provided in the washing nozzle 27, and the washing water is sprayed from the washing nozzle 27 to perform the first washing operation. The bottom of the cleaning tank 22 is provided with a drain 28 communicating with the suction side of the cleaning...

Embodiment 2

[0084] Figure 10 Shows a sectional view of key parts of a dishwasher provided with a cleaning device in the second embodiment of the present invention, its basic composition is the same as figure 1 same as in Figure 1 to Figure 9 The same components are marked with the same symbols. Wherein, the cleaning water storage part 36 is completely separated from the cleaning tank 22, and the cleaning water storage part 36 is provided with a second water inlet valve 45 for water intake and a drain valve 46 for water discharge. In addition, the cleaning water storage part 36 is also provided with a cleaning agent dissolving device 47 for stirring the cleaning water to promote the dissolution of the cleaning agent, and a blower device used as a particle scattering device 48 for stirring the scattered fine particles in the cleaning tank 22. .

[0085] During operation, the user first puts cleaning agent in the specified position, and then starts the cleaning operation. After the op...

Embodiment 3

[0092] Figure 11 and Figure 12 It is a cross-sectional view of the key parts of the dishwasher provided with the cleaning device in the third embodiment of the present invention, and its basic composition is the same as figure 1 same as in Figure 1 to Figure 10 The same constituent parts are marked with the same symbols, and the receiving portion 49 adopts another embodiment. Figure 11 Among them, a sink-type receiving portion 49 is provided at the place where the water column falls, and the size of the cleaning water storage portion 36 remains unchanged. Thus, in the process of recovering the washing water into the washing water storage portion 36, the water column A of washing water is not blocked halfway, so that the same operation and effect as in the first embodiment can be obtained. If the water column A is blocked in the middle, the scattering amount of fine particles will be reduced. use Figure 11 With the structure shown in , it is possible to generate more...

Abstract

To improve the washing effects of a dishwasher by washing dishes with highly concentrated washing solution without increasing the quantity of a detergent to be used. The dishwasher comprises a washing solution storage part 36 in which the washing solution is stored, and an ultrasonic vibration part 37 for scattering the washing solution inside a washing tub 22. The washing solution raised from the water surface by the vibration of the ultrasonic vibration part 37 is collected in the washing solution storage part 36. The washing solution with high detergent concentration is micronized using an ultrasonic vibrator 38 and scattered with only a very small quantity of washing solution. With the action of highly concentrated components of the detergent such as alkali, a surfactant and a bleaching agent on the stain, the stain can be powerfully removed.

Description

technical field [0001] The invention relates to a washing device and a dishwasher provided with such a washing device. Background technique [0002] The structure of the existing dishwashing machine provided with cleaning device is as follows: Figure 24 (for one example, refer to Japanese Patent Laid-Open No. 2003-339607). Next, its configuration will be described. Such as Figure 24 As shown in , the dish washing machine is equipped with: a washing tank 1 for loading tableware and other objects to be cleaned; a door 2 for opening / closing the washing tank 1; a water inlet valve 3 for adding water to the washing tank 1 ; a washing pump 4 for pressurizing washing water; and a spraying device 5 having a spray port for spraying washing water. When performing the cleaning operation, the user first loads the object to be cleaned into the cleaning tank 1, then puts cleaning agent into the cleaning tank 1, and then closes the machine door 2 to start the cleaning operation. [00...
