Description

Mist generating device, dish washer and washing machine

technical field

The present invention relates to a mist generating device for atomizing a liquid by a mist generating oscillator, and a dish washer and washing machine provided with the mist generating oscillator.

Background technique

The structure of an existing general dishwasher is shown in FIG. 8 . The composition thereof will be described in detail below.

As shown in FIG. 8 , a washing tank 802 is provided inside the dishwasher 801 , and a water inlet valve 803 is used to supply normal temperature water or hot water into the washing tank 802 . The cleaning pump 805 communicates with the drain hole 804 provided at the bottom of the cleaning tank 802 , and the cleaning pump 805 circulates the cleaning water inside the cleaning tank 802 under the drive of the motor. In addition, a leftover filter 806 for collecting leftovers is provided on the drain hole 804 .

The cleaning water supplied into the cleaning tank 802 passes through the leftover filter 806, is sucked by the cleaning pump 805, and is supplied to the cleaning nozzle 807 provided on the bottom of the cleaning tank 802 by the cleaning pump 805. The washing water is ejected from the washing nozzle 807, washes the objects to be washed (dishes) 808, and then returns to the drain hole 804 again to circulate through the above-mentioned path. At this time, the leftovers and the like that fall off from the object to be cleaned 808 flow into the leftovers filter 806 together with the cleaning water, and the leftovers that are too large to pass through the leftovers filter 806 are passed by this leftovers filter. 806 capture/collect up.

In addition, a heater 809 for heating the washing water is provided between the washing nozzle 807 and the bottom surface of the washing tank 802 . A cutlery basket 810 is arranged above the cleaning nozzle 807, the purpose of which is to make the objects 808 to be cleaned neatly arranged, and to enable cleaning water to be effectively sprayed on the objects 808 to be cleaned, thereby improving cleaning efficiency. The drain pump 811 is used to drain the dirty washing water out of the machine through the drain hose 811a. In addition, the control device 812 is used to drive and control electrical components such as the water inlet valve 803 and the cleaning pump 805 . The above technical contents are disclosed in Japanese Patent Publication No. 2003-210378.

However, even in the dishwasher having the structure shown in FIG. 8 , there is a limitation that not all the dirt adhering to the object 808 to be washed can be washed off. Especially, for the tableware directly heated in the cooking process and the tableware with scorched marks (such as the containers of gratin, chawanmushi, etc.), the cleaning effect is not ideal.

One way to solve this problem is to implement a pretreatment step before officially starting the cleaning operation, that is, first make the object to be cleaned 808 adhere to a cleaning agent solution with a higher concentration than the cleaning agent concentration in normal use, and then Leave it for a while. After implementing such a pretreatment step, the cleaning performance can be greatly improved, and the dish dirt that cannot be washed off by the existing washing machine can also be cleaned.

In order to attach a high-concentration detergent solution to the object to be cleaned, for example, a mist generator with an ultrasonic oscillator for generating mist can be used. However, in this way, food stains in the washing water of the dishwasher 801 and inorganic substances in hard water with high hardness such as well water will be precipitated, and these foreign substances will adhere and solidify on the vibrating surface of the ultrasonic oscillator. As a result, the operation of the ultrasonic oscillator will be affected, and the amount of nebulization produced will be significantly reduced. In severe cases, problems such as failure of the ultrasonic oscillator itself and operation becoming impossible may occur.

Atomize the liquid used to generate atomization on the outside of the container, and set a cleaning agent input part in a manner adjacent to or extending from the surface facing the mist generating oscillator, and the mist The surface facing the generating oscillator is arranged to be inclined to one side.

This structure prevents foreign matter from directly adhering and solidifying on the surface of the mist generating oscillator, thereby preventing the operation of the mist generating oscillator from being affected, a significant drop in the amount of atomization, failure of the mist generating oscillator, and stoppage of operation, etc. Unfavorable situations occur, and stable atomization can occur even in the atomized liquid that has become dirty. In addition, the ultrasonic vibration output from the mist generating oscillator can effectively atomize the liquid outside the container through the liquid and the thin film, so that the atomization can be performed efficiently and stably.

Detailed ways

Various embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the following examples do not limit the technical scope of the present invention.

(first embodiment)

Next, a first embodiment in which the mist generating device of the present invention is applied to a dishwasher will be described with reference to FIGS. 1 and 2 .

In the dishwasher 1 according to the first embodiment of the present invention, as shown in FIG. 1 , a mist generator 13 is provided on the front and lower side of the washing tub 2 . The structure of this mist generating device 13 is as shown in Figure 2, and the bottom surface is provided with the mist generating oscillator 14 that is made of ultrasonic oscillator, and the upper side of its vibrating surface is provided with the container 16 that is sealed with sealing liquid 15, described The enclosed liquid 15 and the container 16 are integrated. Furthermore, the surface of the container 16 facing the ultrasonic oscillator 14 is formed by a film 17 . In this way, the ultrasonic vibration caused by the mist generating oscillator 14 vibrates the film 17 on the container 16 through the sealed liquid 15, and the liquid (cleaning water) for misting outside the container 16 is atomized. The enclosed liquid 15 here is distilled water. The shape of the container 16 is set so that even if the enclosed liquid 15 permeates through the wall surface of the container 16 in the form of water vapor, and the amount of the enclosed liquid 15 decreases, the liquid level of the enclosed liquid 15 can be located above the film 17. , will always be able to submerge the membrane 17.

Here, the container 16 is made of a material with low water vapor permeability and little absorption of ultrasonic waves, and the most suitable material is unfilled polytetrafluoroethylene (PPS) or the like. In addition, the thickness of the film 17 constituting the face facing the mist generation oscillator 14 of the container 16 is preferably set such that it is the wavelength when the ultrasonic vibration generated by the mist generation oscillator 14 propagates along the wall of the container 16. About 1/2 of that. When the thin film 17 is unfilled polytetrafluoroethylene, its thickness is about 0.5 mm. In addition, a detergent input portion 18 for carrying detergent is provided near the periphery of the membrane 17 so as to generate a high-concentration detergent solution above the membrane 17 facing the mist generating oscillator 14 .

The operation and function of the above structure will be described in detail below. In the mist generating device 13, since the container 16 enclosing the liquid 15 is provided above the mist generating oscillator 14, the mist generating oscillator 14 does not come into direct contact with the washing water. Therefore, even when the dishwasher 1 is working, the mist generating oscillator 14 will not come into contact with the washing water that may become very dirty, thereby preventing the remaining food that becomes muddy from adhering to and solidifying on the mist generating oscillator 14. on the vibrating surface. In this way, failure of the mist generating oscillator 14 can be prevented, and stable operation can be achieved for a long period of time.

In addition, even if the mist generator 13 does not come into contact with the washing water that may become very dirty in the dishwasher 1, if water with very high hardness such as well water is used, the inorganic components in the water will be precipitated. Attached to the vibrating surface of the mist generating oscillator 14. Therefore, even when the water appears to be very clean, the surface of the mist generating oscillator 14 may adhere to the inorganic substance and solidify, which may also affect its operation. However, the use of the mist generating device 13 can prevent such a phenomenon from occurring, and the original goal of misting the liquid can be stably achieved for a long period of time. Therefore, this embodiment is very effective in a device that performs mist using the mist generating oscillator 14 composed of an ultrasonic oscillator.

After the face facing the mist generation oscillator 14 is made of a thin film 17, the penetration of ultrasonic vibration can be improved, and the liquid used to generate atomization can also be atomized with high efficiency, thereby improving cleaning. performance. In addition, when the film 17 is used to form the surface facing the mist generating oscillator 14, the amount of ultrasonic vibration energy absorbed by the container 16 can be reduced, thereby preventing the film 17 from being dissolved under the action of ultrasonic waves.

In addition, since the container 16 is made of a material with low water vapor permeability and low ultrasonic absorption, even if it is used for a long time, the amount of the liquid 15 sealed in the container 16 permeating to the outside through the container 16 will decrease, and there is no need to The sealing liquid 15 is added and replenished. In addition, since the container 16 is made of a material that absorbs little ultrasonic vibration, the container 16 itself will not be dissolved by the ultrasonic vibration, and stable atomization can be constantly generated.

The thickness of the film 17 facing the mist generation oscillator 14 in the container 16 is due to the setting of 1/2 of the wavelength when the ultrasonic wave generated by the mist generation oscillator 14 propagates along the film 17 facing the mist generation oscillator 14 Therefore, the transmittance of the ultrasonic waves in the film 17 facing the mist generating oscillator 14 can be maximized, so that the amount of atomization can also be maximized.

Next, the operation of the dishwasher 1 will be described in detail. First, a predetermined amount of cleaning agent is charged into the cleaning agent input portion 18, and the cleaning operation is started. After the operation starts, the control device 12 first opens the water inlet valve 3, and adds cleaning water of a prescribed amount. At this time, the control device 12 sets/controls the inflow water level to be above the detergent input portion 18 .

When the cleaning water enters the inside of the cleaning agent input portion 18, a part of the cleaning agent dissolves in the cleaning water. At this time, start to drive the mist generating oscillator 14 to work, and its vibration will propagate into the enclosing liquid 15, and pass through the enclosing liquid 15, so that the surface facing the mist generating oscillator 14, that is, the film 17, vibrates. Here, the position of the film 17 facing the mist generating oscillator 14 is set at a position where the vibration amplitude of the mist generating oscillator 14 can be maximized, so that the film 17 facing the mist generating oscillator 14 can Generate a lot of vibration.

Such vibration vibrates the washing water located above, thereby atomizing the washing water. Simultaneously, the cleaning agent dropped into the cleaning agent input portion 18 is dissolved, and the high-concentration cleaning solution is scattered into the cleaning tank 2, and such high-concentration cleaning solution will adhere to the object 8 to be cleaned. In addition, when there is no cleaning water above the film 17 facing the mist generating oscillator 14, the atomization will of course stop, and the high-concentration cleaning agent solution will no longer scatter. Therefore, when the mist generating oscillator 14 is driven to work, the control device 12 controls the water inlet valve 3 so that there must be cleaning water above the membrane 17 .

By performing the pretreatment process of the cleaning process, that is, as described above, the high-concentration detergent solution is scattered into the cleaning tank 2 by the mist generator 13, and such a high-concentration detergent solution is attached to the object 8 to be cleaned. , and then placed in such a state for an appropriate time, the dirt attached to the object to be cleaned 8 can be chemically decomposed by a high-concentration cleaning agent solution.

Then, in the formal cleaning process after the pre-treatment process, the method in the existing dish washing machine is used to clean the dirt after the specific dirt has been decomposed by the high-concentration detergent solution in the pre-treatment process. .

When cleaning the dirt on the object 8 to be cleaned, temperature and mechanical force (momentum of the cleaning water sprayed from the cleaning nozzle 7) have a great effect. However, for those dirt that have been chemically decomposed in the pre-treatment process, chemical decomposition alone cannot clean it away, and it also depends on temperature and mechanical force to reliably clean it away. However, for those dirt that cannot be cleaned by existing methods, the decomposition process that occurs during the period of time after the high-concentration cleaning agent solution is attached in the pretreatment process is very important for effectively cleaning them. role.

As mentioned above, since the mist generating device 13 in the first embodiment of the present invention adopts a structure in which the cleaning water (liquid for generating atomization) outside the container 16 is atomized by enclosing the liquid 15 and the container 16, It can prevent foreign matter from directly adhering to and solidifying the surface of the mist generating oscillator 14, and can prevent adverse situations such as affecting the operation of the mist generating oscillator 14, a significant drop in the amount of atomization, and the mist generating oscillator 14 malfunctioning and stopping its operation. , Even in dirty cleaning water, atomization can be stably generated.

In addition, since the above-mentioned mist generator 13 is provided in the dish washer 1 to atomize the washing water for washing the tableware, the washing water in the washing tank 2 becomes very dirty even if there is a lot of dirt on the food, etc. It can also stably atomize high-concentration cleaning agent solution under the condition of In addition, since the mist generating device 13 can make the cleaning agent solution with a concentration higher than that in normal use be scattered and uniformly attached to the object 8 to be cleaned, it is possible to perform the process of making the high-concentration cleaning agent solution adhere to the object to be cleaned. The pre-processing stroke of cleaning object 8 and placing it for a period of time. In addition, under the chemical action of the high-concentration cleaning agent attached to the object to be cleaned 8, the cleaning performance can be greatly improved, so the dish dirt that cannot be cleaned in the existing device can also be cleaned. Furthermore, by making the face facing the mist generating oscillator 14 constituted with the thin film 17 and made of a material with less ultrasonic absorption, the ultrasonic wave itself will not cause the thin film facing the mist generating oscillator 14 17 dissolved.

In addition, although the example in which distilled water is added as the enclosed liquid 15 is shown in the first embodiment of the present invention, there is nothing special about using other liquids capable of propagating vibrations such as salt water and polypropylene glycol aqueous solution. question.

(second embodiment)

Next, a second embodiment of the present invention will be described with reference to FIG. 3 . In addition, when new embodiments are described below, the same components as those of the previously described embodiments are assigned the same reference numerals, and repeated description thereof will be omitted, and only differences will be described.

In the second embodiment of the present invention, as shown in FIG. 3 , the thin film 17 has a structure in which a concave portion 19 is formed on the surface facing the mist generating oscillator 14 in the container 16 of the mist generating device 13 . In addition, the concave portion 19 is provided on the surface side in which the liquid 15 is sealed. In addition, this concave portion 19 is formed by compressing a part of the surface facing the mist generating oscillator 14 in the thickness direction after resin injection when extruding the container 16 .

After adopting this structure, since the film 17 is formed after forming the concave portion 19 on the surface facing the mist generating oscillator 14 in the container 16, even if the container 16 is molded with a resin with poor fluidity, it can The part through which the ultrasonic vibration passes is made very thin. In this way, the absorption of ultrasonic waves is small, and the ultrasonic waves themselves do not dissolve the container 16, and stable atomization can be constantly generated.

In addition, in order to provide the concave portion 19 on the surface facing the mist generating oscillator 14 of the container 16, when the container 16 is extrusion-molded, it is possible to pass the surface facing the mist generating oscillator 14 after resin injection. A part of the surface is compressed in the thickness direction to form the concave portion 19 . Therefore, even a resin material with poor fluidity can form a thin film. As a result, the absorption of ultrasonic waves can be reduced, and the ultrasonic waves themselves do not dissolve the container 16, and stable atomization can be constantly generated.

(third embodiment)

Next, a third embodiment of the present invention will be described in detail with reference to FIG. 4 .

In the third embodiment of the present invention, as shown in FIG. 4, in the container 16 of the mist generating device 13, an opening 16a is formed on the face facing the mist generating oscillator 14, and the opening 16a It is airtightly covered by the sheet-like resin 20 constituting the film 17 described above.

After adopting this structure, since an opening 16a is provided on the face facing the mist generating oscillator 14 of the container 16, and this opening 16a is airtightly covered by the sheet-like resin 20 to form the film 17, Therefore, even if the container 16 is formed of a resin with poor fluidity, the thin film 17 through which ultrasonic waves can easily pass can be formed on the surface of the container 16 facing the mist generating oscillator 14 . In addition, by constituting the thin film 17 with a sheet-like resin 20 that absorbs little ultrasonic waves, the container 16 can be prevented from being dissolved by the ultrasonic waves itself, and stable atomization can be performed constantly.

(fourth embodiment)

Fig. 5 is a cross-sectional view of an example of installing the mist generator in a fourth embodiment of the present invention in a washing tank filled with washing water.

In FIG. 5 , the mist generating device 53 includes: a container 56 enclosing a liquid 55 ; and a mist generating oscillator 54 which is formed of an ultrasonic oscillator and is arranged at the bottom of the container 56 . The top surface 57 at the position facing the mist generating oscillator 54 in the container 56 corresponds to the film 17 in the first embodiment 1 of the present invention. That is, when the mist generating oscillator 54 is driven, the top surface 57 constitutes a vibrating surface that vibrates under the action of the vibration transmitted from the mist generating oscillator 54 through the liquid 55 . In addition, the liquid 55 enclosed in the container 56 is preferably distilled water.

The top surface 57 is provided to be inclined to one side as shown in FIG. 5 , and is formed of resin that easily vibrates. In addition, this top surface 57 is formed with a concave portion 57b that is depressed into an arc shape, and the center of the arc shape is the central portion 57a where the vibration of the mist generating oscillator 54 propagates (that is, the center portion passing through the center of the mist generating oscillator 54 ). The part where the vertical line intersects with the surface of the top surface 57). In addition, one end of the upper surface of the top surface 57 is provided with a cleaning agent input portion 58 for carrying a cleaning agent 58a.

The operation and function of the mist generating device 53 with the above-mentioned structure will be described in detail below.

When the mist generating oscillator 54 is driven, the vibration of the mist generating oscillator 54 propagates to the top surface 57 through the liquid 55, causing the top surface 57 to vibrate, thereby atomizing the cleaning water above the top surface 57.

Adopt the word of the 4th embodiment of the present invention as described above, the upper side of the mist generation vibrator 54 only contacts with the liquid 55 enclosed in the container 56, and the surface of the mist generation vibrator 54 does not directly contact with the cleaning water. Therefore, in the equipment that will contact the washing water that may become very dirty, such as the dish washing machine, even if the mist generator 53 is installed so that the side of the top surface 57 is adjacent to the washing water, it is possible to reliably prevent the food from becoming muddy. The phenomenon that the mist is adhered and solidified on the vibrating surface of the vibrating oscillator 54 after being shaped. In addition, problems such as failure of the mist generating oscillator 54, influence on the operation of the mist generating oscillator 54, and a significant decrease in the amount of atomization do not occur, and atomization can be performed stably for a long period of time even in dirty washing water.

In addition, even if the dishwasher does not touch the washing water that may become very dirty, but uses water with very high hardness such as well water, after adopting this embodiment, it will not adhere to the surface of the mist generating oscillator 54. The original intention of the design is that the inorganic components will not affect its operation, and the liquid atomization can be stably realized for a long time. Therefore, it is very effective in a device for misting using the mist generating oscillator 54 .

Here, the reason why the top surface 57 is provided as an inclined surface is because when air bubbles are generated from the liquid 55 sealed in the container 56, the air bubbles will adhere to the lower surface of the center portion of the top surface 57, causing the mist to oscillate. The vibration generated by the device 54 is difficult to propagate to the top surface 57; and by making the air bubbles move high along the inclined surface, it can be separated from the center of the vibration. In addition, the reason why the concave portion 57b is provided on the top surface 57 is that the atomization amount of the high-concentration cleaning agent solution can be increased after the concave portion 57b is provided compared with the planar shape alone. The reason is that after the concave surface is provided, the vibration energy of the mist generating oscillator 54 can be more concentrated towards the center.

In addition, since the top surface 57 above the container 56 is made of resin and the concave portion 57b is provided thereon, by using a resin material close to the vibration state of the liquid 55 enclosed in the container 56, vibration stability can be ensured. In addition, since the energy of the vibration of the mist generating oscillator 54 can be concentrated and effectively functioned, it is possible to generate a large amount of mist stably at all times.

In addition, although distilled water is sealed in the container 56 in the 4th embodiment of the present invention, liquids such as salt water that can propagate vibrations also can be used, wherein with non-corruption, non-explosive liquid is the best. In addition, although the top surface 57 is made of resin that is easy to vibrate, it may be made of metal or the like depending on the power of the mist generating oscillator 54, and there is no problem as long as it can vibrate. In addition, although the uniform concave portion 57b is provided on the top surface 57 in this embodiment, it is also possible to make the inner surface of the container 56 horizontal, and then form a concave lens shape on the other side. In this way, the outside of the container 56 will be recessed. As long as the vibration energy can be concentrated to the center and used effectively.

(fifth embodiment)

Next, a fifth embodiment in which the mist generating device of the present invention is applied to a washing machine will be described in detail with reference to FIGS. 6 and 7 .

In the washing machine 621 in Embodiment 5 of the present invention, as shown in FIG. 6 , a mist generating device 622 is provided inside the machine body of the washing machine 621 . The structure of this mist generating device 622 is shown in Fig. 7, and its bottom surface is provided with the mist generating oscillator 623 that is made of ultrasonic oscillator, and the upper side of the vibrating surface of mist generating oscillator 623 is provided with and is packaged with enclosing liquid 624. The container 625 vibrates the film 626 on the top surface facing the mist generation vibrator 623 in the container 625 by enclosing the liquid 624, and the liquid (washing water) that is used to generate atomization outside the container 625 is added to the container 625. Atomization.

In addition, on the upper surface of the film 626 facing the mist generating oscillator 623, a cleaning agent injection part 627 for injecting cleaning agent is formed. The material of the thin film 626 facing the mist generating oscillator 623 is resin that vibrates easily, and its shape is an inclined surface. In addition, the sealing liquid 624 is distilled water.

The operation and effect of the above-mentioned device configuration will be described below. First, the configuration and washing operation of the washing machine 621 in the fifth embodiment of the present invention will be described. In the washing stroke, first put into the clothes (washing) in the inner bucket 628, and then start the operation; after the operation starts, first open the water inlet valve 629 to add the water of the specified water level, and then make the motor 630 (Fig. 6) start to rotate. At this time, the power of the motor 630 is transmitted to the pulsator 631 through the washing shaft, so that the pulsator 631 rotates, and the clothes are stirred in the water to be washed; then, the drain valve 632 is opened to drain water. In the rinse cycle, water is added again, and the laundry is rinsed clean by the same operation as in the wash cycle.

After rinsing, the dehydration process is performed. During the dehydration process, firstly open the drain valve 632 to drain the water in the inner tub 628, and then transmit the power of the motor 630 to the inner tub 628 through the dehydration shaft to make the inner tub 628 rotate, and add centrifugal force to the clothes to remove the water from the clothes Separation in order to achieve dehydration.

Compared with the above operation in the washing machine 621, the fifth embodiment of the present invention also has a pre-washing process. When doing laundry, open the cleaning agent injection cover 633, put in the cleaning agent in advance, and then place the cleaning agent injection cover 633 in a closed state. Next, laundry (laundry) is put into inner tub 628 to start the washing operation. After the operation starts, add water (used to realize washing water for washing) from the water inlet valve 629 to the cleaning agent input portion 627. The water inflow time is set so that the cleaning agent input portion 627 can be substantially filled with water. Here, even if a little more water is added, it will overflow from the cleaning agent input part 627, so the water level can be kept constant. A portion of the cleaning agent begins to dissolve at this point.

At this time, the mist generating oscillator 623 is driven to work, and its vibration will propagate in the enclosing liquid 624 and pass through the enclosing liquid 624 to vibrate the film 626 facing the mist generating oscillator 623 in the container 625 . The position of the film 626 facing the mist generating oscillator 623 is set so that the vibration amplitude of the mist generating oscillator 623 can be maximized, so that the thin film 626 facing the mist generating oscillator 623 can generate a large amount of vibration. big vibration.

Under the action of such vibration, the cleaning water used for washing at the upper side will vibrate, thereby atomizing the cleaning water; at the same time, the cleaning agent put into the cleaning agent input part 627 will dissolve while being used to realize cleaning. The high-concentration detergent solution contained in the cleaning water will scatter.

In this way, the cleaning water or the high-concentration cleaning solution containing the atomized cleaning agent will be scattered in the inner barrel 628, and the misty high-concentration cleaning solution will be attached to various positions of the clothing. . By leaving it in this state for an appropriate time, the high-concentration detergent solution will chemically decompose the dirt attached to the clothes and the like. After that, perform normal operations from washing to spinning.

Therefore, in the fifth embodiment of the present invention, instead of atomizing the washing water which has become very dirty, the water just added is atomized. However, as described above, when using water with very high hardness such as well water, the inorganic components therein are also precipitated and adhere to the vibrating surface of the mist generating oscillator 623 . Therefore, in such a case, using the mist generating device 622 in the fifth embodiment of the present invention can prevent this from happening, and the liquid can be atomized stably for a long time.

As mentioned above, since the washing machine 621 in the fifth embodiment of the present invention is provided with the mist generating device 622, and the washing water used for washing is atomized, stable mist can also be generated in the washing water used for washing. change. In addition, the mist generating device 622 can implement the following pretreatment process, that is, make the detergent solution with a concentration higher than that in normal use evenly adhere to the laundry, and then leave it for a period of time, so that it can rely on the detergent solution attached to the laundry. The chemical action of the high-concentration cleaning agent on the object greatly improves the cleaning effect.

In addition, in the fifth embodiment of the present invention, although the structure in which the mist generating device 622 is arranged inside the machine body of the washing machine 621 and water is added to the cleaning agent input part 627 from the water inlet valve 629 is adopted, the mist generator can also be used. The generating device 622 is arranged in the outer barrel 634 that wraps the inner barrel 628 inside it, and then the cleaning water used to realize washing in the outer barrel 634 is added to the cleaning agent input part 627 to form a high-concentration cleaning agent solution, and then Such a high-concentration detergent solution is atomized, scattered into the inner tub 628, and adhered to the clothes. In this way, the same action and effect can also be achieved.

In summary, the mist generating device of the present invention can prevent foreign matter from directly adhering and solidifying on the surface of the mist generating oscillator, thereby preventing the operation of the mist generating oscillator from being affected, the amount of atomization significantly reduced, and the fog from being generated. Occurrence of unfavorable conditions such as oscillator failure, inoperability, etc. In addition, since atomization can occur stably even in hard water and dirty liquid used for atomization, it can be applied to dish washing machines and washing machines, etc., and the cleaning effect is greatly improved.
