It is supplied to the installed washing nozzle 7. The washing water injected from the washing nozzle 7 circulates in the path that returns to the drain hole 4 after washing the object to be cleaned (tableware) 8 again. At this time, the dregs and the like removed from the object to be cleaned 8 flow into the dreg filter 6 together with the washing water, and dregs having a size that cannot pass through the dreg filter 6 are collected in the dreg filter 6. do.

In addition, a heater 9 for washing water heating is attached between the washing nozzle 7 and the bottom of the washing tank 2. Furthermore, above the washing nozzle 7, the object to be cleaned 8 can be arranged squarely, and a dish basket 10 configured to spray the washing water to the object to be cleaned 8 is provided.

Moreover, the control unit 12 drives and controls electric components, such as the water supply valve 3 and the washing | cleaning pump 5, for example. A dishwasher having the above structure is disclosed in Japanese Patent Laid-Open No. 2003-210378.

However, in the said structure, it was not able to wash | clean completely about all the dirts wash | cleaned with a dishwasher.

In particular, it is troublesome about the cooking which cooks by heating directly and pressing. As an example, a dish, such as a gratin and a steamed dish, is mentioned.

As this solution, the cleaning performance can be significantly improved by having a pretreatment step in which a detergent liquid having a higher concentration is attached to the object to be cleaned than the detergent concentration in normal use and left to stand. In this way, the contamination of the dish which was not removed conventionally can be wash | cleaned.

Here, when the mist generating apparatus equipped with the ultrasonic vibrator for mist generation is used in order to attach a high concentration detergent liquid to the to-be-cleaned object, a hard water path with high hardness in the contamination of the food contained in the washing water of a dishwasher, well water, etc. By depositing the inorganic components from the particles, these foreign matters adhere to the vibration surface of the ultrasonic vibrator and solidify. As a result, it affects the operation of the ultrasonic vibrator, causing a significant decrease in the amount of mist or, in severe cases, a failure in which the ultrasonic vibrator itself breaks down and becomes inoperable.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and prevents foreign matter from directly adhering to the surface of the mist generating vibrator and solidifies, affecting the operation of the mist generating vibrator, resulting in a significant decrease in the amount of mist or mist. The first object of the present invention is to prevent the generation of a defect in which the generating vibrator is broken and inoperable, and to enable stable mist generation even in contaminated washing water.

A second object of the present invention is to allow a high concentration of detergent liquid to be stably even in a washing tank of a dish washing machine with a lot of contamination such as food, and to improve the cleaning performance.

Similarly, in the washing machine with many contaminations, the third object is to improve the cleaning performance by stably washing the washing water for washing and attaching a high concentration of the detergent liquid to the object to be cleaned.

The mist generating apparatus of this invention is comprised so that the container which sealed liquid may be provided in the vibrating surface side of the mist generating vibrator, and is configured to mist the liquid for mist outside of a container through the sealed liquid and a container.

Moreover, the dishwasher of this invention is comprised so that the said mist generating apparatus may be misted | cleaned the washing water which wash | cleans dishes.

Moreover, the washing machine of this invention is comprised so that the said mist generating apparatus may be made to mist wash washing water for washing.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits detailed description. In addition, this invention is not limited by each Example. The frequency of the ultrasonic wave in this invention belongs to the range of 20 KHz to 10 MHz, and the frequency of 2 MHz-3 MHz is preferable.

(First embodiment)

As shown in FIG. 2, the mist generating device 13 is disposed below the front face of the cleaning tank 2. This mist generating apparatus 13 arrange | positioned the ultrasonic vibrator (mist generation vibrator) 14 on the lower surface as shown in FIG. 1, and enclosed the sealing liquid (liquid) 15 on the upper side of the vibration surface. The container 16 is arrange | positioned. And the surface 17 which opposes the ultrasonic vibrator 14 of the container 16 via the sealing liquid 15 and the container 16 is vibrated, and the mist liquid (clean water) of the container 16 outside is vibrated. It is configured to mist. In addition, the sealing liquid 15 is made into distilled water.

Here, the surface 17 which faces the ultrasonic vibrator 14 of the container 16 is made into the inclined surface, and is comprised from resin which is easy to vibrate. Moreover, the detergent inlet part 18 which injects detergent into the upper surface of the surface 17 which opposes the ultrasonic vibrator 14 is comprised.

The operation and operation in the above configuration will be described. In the mist generating apparatus 13, since the container 16 which enclosed the sealing liquid 15 was arrange | positioned above the ultrasonic vibrator 14, the ultrasonic vibrator 14 does not directly contact wash water. Therefore, even when the dishwasher is operated, it does not come into contact with very contaminated washing water. In this way, the food becomes a slime shape and can be prevented from adhering to the vibrating surface of the ultrasonic vibrator 14 and solidifying. As a result, the ultrasonic vibrator 14 does not fail and can continue to operate stably.

In addition, even when very dirty water, such as a dishwasher, is not handled, when very high hardness water is used in well water or the like, the inorganic component precipitates and adheres to the vibrating surface of the ultrasonic vibrator 14.

Therefore, even when simple water is used, in some cases, an inorganic component may adhere and solidify on the surface of the ultrasonic vibrator 14 to affect its operation. Even in such a case, such a phenomenon can be prevented by using this mist generating apparatus 13.

That is, by using this mist generating apparatus 13, since misting of the liquid of the original objective can be performed stably over a long period of time, it is very effective in the apparatus which performs misting using the ultrasonic vibrator 14. As shown in FIG.

Next, the operation of the dish washing machine of the present embodiment will be described.

First, when a predetermined amount of detergent is introduced into the detergent injecting unit 18 to start the operation, the water supply valve 3 is opened by the control means 12 to supply a predetermined amount of washing water. At this time, the control unit 12 sets and controls the water supply level so as to be above the detergent inlet 18.

Washing water penetrates into the detergent inlet 18, and part of the detergent is dissolved in the washing water. At this point, when the ultrasonic vibrator 14 is driven, the vibration propagates through the encapsulating liquid 15 and passes through the encapsulating liquid 15 and the container 16 so as to face the ultrasonic vibrator 14. Vibrate. At this time, if the position of the surface 17 facing the ultrasonic vibrator 14 is arranged at a position where the vibration amplitude of the ultrasonic vibrator 14 is maximum, the surface 17 facing the ultrasonic vibrator 14 is positioned. It can vibrate greatly.

By this vibration, the washing water on the upper surface is further vibrated to make the washing water mist, and at the same time, the detergent set in the detergent inlet 18 is also melted, and a high concentration of detergent liquid is scattered in the washing tank 2, This high concentration detergent liquid can be attached to the object to be cleaned 8. When the washing water disappears above the surface 17 facing the ultrasonic vibrator 14, the generation of mist is also stopped and the detergent solution of high concentration is not scattered. Therefore, when the control unit 12 drives the ultrasonic vibrator 14, the control unit 12 controls the water supply valve 3 so that the washing water can be washed above the surface 17 facing the ultrasonic vibrator 14.

Here, the reason for making the vibrating surface 17 an inclined surface is as follows. When bubbles are generated from the encapsulating liquid 15 enclosed in the container 16, when bubbles are attached to the lower side of the surface 17 facing the ultrasonic vibrator 14, the vibration of the ultrasonic vibrator 14 causes the ultrasonic vibrator 14 to vibrate. It is difficult to propagate to the surface 17 opposite to). In order to prevent this, the bubble is moved along the inclined plane so as to deviate from the center of vibration.

As a pretreatment step of the washing step, as described above, the mist generating device 13 scatters a high concentration of the detergent liquid in the washing tank 2, and attaches the high concentration detergent liquid to the object to be cleaned 8. Leave it in a state. A high concentration of detergent liquid chemically decomposes the contamination adhering to the object to be cleaned 8.

In the present cleaning step after the pretreatment step, the conventional dishwasher is cleaned for the contamination after the specific contamination is decomposed by the detergent solution of high concentration in the pretreatment step.

With respect to the dirty cleaning of the object to be cleaned 8, the temperature and the mechanical force (the intensity of the injection of the cleaning water from the cleaning nozzle 7) have a great influence.

In addition, it is not only possible to clean the contaminants decomposed in the pretreatment stroke but also to reliably clean them by temperature or mechanical force. However, the decomposition of contamination by neglect after high concentration of detergent liquid in this pretreatment stroke is very effective against the kind of contamination which has not fallen in the past.

As described above, the mist generating device 13 of the present embodiment is configured to mist the washing water (liquid for mist) outside the container 16 via the sealing liquid 15 and the container 16. As a result, since foreign matter adheres directly to the surface of the ultrasonic vibrator 14 and can be prevented from solidifying, it may affect the operation of the ultrasonic vibrator 14, resulting in a significant decrease in the amount of mist or the ultrasonic vibrator 14. It is possible to prevent the occurrence of a defect that is not operating due to the failure. That is, stable mist generation can be performed even in contaminated washing water.

Moreover, since the surface 17 facing the ultrasonic vibrator 14 formed in the container 16 is inclined, even if bubbles are generated from the encapsulating liquid 15 enclosed in the container 16, the ultrasonic vibrator 14 Bubbles can be prevented from adhering to the opposing face 17. As a result, stable mist generation can always be performed.

Moreover, since the surface 17 which opposes the ultrasonic vibrator 14 formed in the container 16 was comprised with resin, by using the resin material close to the vibration state of the sealing liquid 15 enclosed in the container 16, , Stable vibration can be secured. In this way, stable mist generation can always be performed.

In addition, in the dish washing machine of the present embodiment, the mist generating device 13 is provided so that the washing water for washing the dishes and the like is misted. Even if inside, it can stably mist high detergent liquid.

Furthermore, since the detergent liquid having a higher concentration than the detergent concentration in normal use can be scattered and adhered to the object to be cleaned, the pretreatment process of attaching the detergent liquid of high concentration to the object to be cleaned can be performed. As a result, since the cleaning performance can be greatly improved by the chemical decomposition power of the high concentration detergent attached to the object to be cleaned, it is possible to clean the contamination of the dish which has not been removed conventionally.

In the present embodiment, distilled water is added as the encapsulating liquid, but any liquid other than the liquid capable of propagating vibration such as brine can be used.

Moreover, although it is comprised from resin which is easy to vibrate as the surface 17 which vibrates against the ultrasonic vibrator 14, even if it is comprised by metal according to the capability of the ultrasonic vibrator 14, there will be no problem as long as vibration generate | occur | produces. At this time, the characteristics of the metal are required to have low vibration attenuation during internal propagation, reflection on the surface, and the like. Moreover, it is more preferable that the thickness of the metal is half of the wavelength of the ultrasonic wave used. From this viewpoint, stainless steel foil etc. are used preferably.

(Second embodiment)

3, the mist generating apparatus 19 is arrange | positioned inside the washing machine main body 20. As shown in FIG. In the mist generating apparatus 19, as shown in FIG. 4, the ultrasonic vibrator (mist generation vibrator) 21 is arrange | positioned at the lower surface, and the encapsulating liquid (liquid) (upper side) of the ultrasonic vibration vibrator 21 is provided above ( The container 23 which enclosed 22 is arrange | positioned. And the surface 24 which opposes the ultrasonic vibrator 21 of the container 23 via the sealing liquid 22 and the container 23 is vibrated, and the mist liquid (clean water) of the container 23 outer side is vibrated. It is configured to mist.

Moreover, the detergent inlet part 25 which injects detergent into the upper surface of the surface 24 which opposes the ultrasonic vibrator 21 is comprised. The surface 24 facing the ultrasonic vibrator 21 is made of a resin which easily vibrates its material, and its shape is an inclined surface. In addition, the sealing liquid 22 is made into distilled water.

In the above configuration, the operation and operation will be described with reference to FIGS. 3 and 4.

First, the configuration and operation of a general washing machine will be described. In the washing stroke, when the clothes (washing matter) are put into the inner tank 26 and operation starts, the water supply valve 27 is opened, water is supplied to a predetermined level, and the motor 28 is driven. At this time, the power of the motor 28 is transmitted to the rotary vanes 29 via the washing shaft, the rotary vanes 29 are rotated, the clothes are stirred under water, washed, and then the drain valve 30 is opened and drained. In the rinse cycle, water is supplied again and the clothes are rinsed in the same manner as the washing stroke.

In the dehydration stroke, after the rinsing is finished, the drain valve 30 is opened to drain the water in the inner tank 26, and then the power of the motor 28 is transmitted to the inner tank 26 via the dehydration shaft to rotate the clothes. Dehydration is performed by separating water from clothes by applying centrifugal force to the clothes.

Regarding the operation of this general washing machine, this embodiment has a pretreatment stroke for washing. The detergent inlet lid 31 is opened to inject detergent in advance, and the detergent inlet lid 31 is closed. When clothing (laundry) is put into the inner tank 26 and operation starts, tap water (washing water for washing) is supplied from the water supply valve 27 to the detergent inlet 25. The water supply time is set so that the tap water is almost full in the detergent inlet 25. Here, even if there is more tap water, the water level is constant by overflowing from the detergent inlet 25. Some detergent will begin to melt at this point.

At this point, when the ultrasonic vibrator 21 is driven, the vibration propagates through the encapsulating liquid 22 and passes through the encapsulating liquid 22 and the container 23 to face the ultrasonic vibrator 21. Vibrate). At this time, if the position of the surface 24 facing the ultrasonic vibrator 21 is disposed at the position where the vibration amplitude of the ultrasonic vibrator 21 is maximum, the surface 24 facing the ultrasonic vibrator 21 is moved. It can vibrate greatly.

By vibrating, the washing water on the upper surface is vibrated to mist the washing water, and at the same time, the detergent set in the detergent inlet 25 is melted, and the detergent solution of high concentration is contained in the washing water. Let's do it. Washing water for washing containing this mist-formed detergent, in other words, a high concentration detergent liquid is scattered into the inner tank 26, and a mist-type high concentration detergent liquid adheres to every corner of the garment. By leaving it as it is, the high concentration detergent liquid chemically decomposes the contamination adhering to clothes.

After that, washing to dehydration are performed as in a normal washing machine.

Since the operation | movement of the mist generating apparatus 19 is the same as that of 1st Embodiment, it abbreviate | omits. However, in the present embodiment, misting is performed on the water supplied rather than the highly contaminated washing water. However, as described above, even when extremely hard water is used in well water or the like, the inorganic component precipitates and adheres to the vibrating surface of the ultrasonic vibrator 21. Therefore, also in this case, it is effective to use the mist generating apparatus 19 of this embodiment, and the mist of the original objective liquid can be stably performed for a long time.

As described above, the washing machine of the present embodiment includes the mist generating device 19 and is configured to mist the washing water for washing. As a result, stable mist generation can be performed even in the washing water for washing, and the mist generating device 19 can carry out a pretreatment stroke in which a detergent liquid having a higher concentration than the detergent concentration in normal use is adhered to the laundry tightly and left to stand. The cleaning performance can be greatly improved by the chemical decomposition power of the high concentration detergent attached to the laundry.

In addition, in this embodiment, the mist generating apparatus 19 is arrange | positioned inside the washing machine main body 20, and it is made to supply water from the water supply valve 27 to the detergent input part 25. As shown in FIG. In addition, the mist generating apparatus 19 is arrange | positioned in the outer tank 32 which contains the inner tank 26, the washing water for washing in the outer tank 32 is thrown into the detergent input part 25, A detergent liquid may be prepared, and the high concentration detergent liquid may be misted, scattered in the inner tank 26 to be attached to clothes, and the same operation and effect as in this embodiment can be obtained.

In addition, the tableware described in this invention means the container and utensils provided for a meal. Examples include air, bowls, small pots and pots, plates, chopsticks, cutlery and forks.

The resin used in the present invention is preferably a resin having a sound impedance close to the encapsulating liquid 15 inside the container and the washing water (any water system) on the outside because of the high radio wave propagation efficiency. For example, polypropylene, PPS, etc. are preferable.

The mist generating apparatus of the present invention can prevent the foreign matter from directly adhering to the surface of the mist generating vibrator and solidify, and affects the operation of the mist generating vibrator to cause a significant decrease in the amount of mist or for mist generation. It is possible to prevent the occurrence of a defect that causes the vibrator to malfunction and becomes inoperable. As a result, stable mist generation can be performed even in a contaminated mist liquid, so that the present invention can be applied to applications such as a dishwasher and a washing machine, and the cleaning performance thereof can be greatly improved.
