However, in such a conventional configuration, the cleaning cannot be performed on all the contamination washed by the dishwasher. In particular, it is difficult for the cooking to be cooked by directly heating and pressing. For example, gratin, steamed dishes and the like.

As a solution, by having a pretreatment step in which a detergent liquid having a higher concentration is attached to the to-be-cleaned object than the detergent concentration in normal use, the cleaning performance can be greatly improved, and the contamination of dishes which have not been obtained conventionally can be cleaned. You can do that.

Here, in order to attach a high concentration of detergent liquid to the object to be cleaned, in the case of using the mist generator having the ultrasonic vibrator for mist generation, the mist generation does not come into contact with the washing water. By arranging the vibration transmitting material above the vibrator and providing a mist generating surface above the vibrator, the washing water can be stably fogged even in the contaminated washing water in a washing tank with a lot of contamination such as food. However, when the added detergent adheres to the mist generation surface, there arises a problem that the mist generation surface self-heats and dissolves by ultrasonic vibration.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and prevents the detergent from being directly mounted on the mist generation surface and prevents the mist generation surface from dissolving, thereby making it possible to stably wash the water, and to use it in normal use. It is an object of the present invention to provide a dishwasher in which a detergent solution having a higher concentration than that of the detergent concentration is tightly adhered to the object to be cleaned, and the cleaning performance is greatly improved by the chemical force of the high concentration detergent attached to the object to be cleaned.

In order to achieve the above object, the present invention comprises a washing tank having an opening for dispensing a to-be-cleaned object such as tableware, a mist for generating vibration, a vibration transmitting material, and a mist generating surface. It is a dishwasher comprised of the mist generation means to mist, and the detergent input part which puts a detergent for washing into this mist generation means, and provided the cover part which covers the mist generation surface.

As a result, the detergent does not directly reach the mist generating surface, and it is possible to prevent the detergent surface from sticking to the mist generating surface, and to prevent the mist generating surface from dissolving by self-heating by ultrasonic vibration. Higher concentration of detergent liquid can be stably attached to the object to be cleaned, and the cleaning performance is greatly improved by the chemical strength of the high concentration of detergent attached to the object to be cleaned.

The dishwasher according to the present invention has a cover portion covering the mist-producing surface, so that the detergent liquid having a higher concentration than the detergent concentration in normal use can be stably and seamlessly adhered to the object to be cleaned. The dishwasher which drastically improved the cleaning performance by the chemical force of a detergent can be realized.

The first invention comprises a washing tank having an opening for dispensing a to-be-cleaned object such as tableware, a mist for generating oscillator, a vibration transmitting material, and a mist generating surface, and generating mist for washing the water in the washing tank. Means and a detergent inlet for putting cleaning detergent into the mist generating means, and by providing a lid portion covering the mist generating surface, the detergent is fixed on the mist generating surface without directly reaching the mist generating surface. It is possible to prevent the mist-forming surface from dissolving by self-heating due to ultrasonic vibration, so that the detergent liquid having a higher concentration than the detergent concentration in normal use can be stably and firmly adhered to the object to be cleaned. The cleaning performance can be significantly improved by the chemical force of the high concentration of detergent attached to the cleaning material.

In the first aspect of the present invention, the detergent injecting portion and the lid portion are integrally formed in the first invention to prevent the fog generation surface from dissolving by self-heating due to ultrasonic vibration in an inexpensive configuration, and thus a high concentration of detergent. The liquid can be stably scattered and adhered to the object to be cleaned without fail, and the cleaning performance can be greatly improved due to the inexpensive configuration.

In the first aspect of the invention, in the first invention, the detergent injecting portion can be supplied to the mist generating means more reliably by providing an inclination portion for detergent injecting, thereby stably scattering a more stable high concentration detergent liquid, It can be attached to a to-be-cleaned object seamlessly, and the cleaning performance can be improved significantly by the structure which is easy to use.

In the fourth invention, in any one of the first to third inventions, the lid portion has a first opening for supplying a detergent to the mist generating means, a second opening in communication with the cleaning tank, and the first opening. By making it narrower than a 2nd opening part, what passed the 1st opening part during washing | cleaning operation can be reliably flown into a washing tank, and the residues, such as a residue on a mist generation surface, can be prevented, In addition to preventing dissolution, the inside of the cleaning tank can be maintained more hygienically, the high concentration of detergent liquid can be stably scattered, and it can be adhered to the object to be cleaned without fail, and the cleaning performance can be greatly improved by the hygienic configuration. .

In the fifth aspect of the invention, in any one of the first to third inventions, the cover portion recovers at least a portion of the washing water scattered from the mist generating means and returns the mist to the mist generating means so that mist forming occurs. Since the density | concentration of a planar washing | cleaning liquid can be raised, a higher concentration detergent liquid can be scattered stably, and it can adhere to a to-be-cleaned object seamlessly, and washing performance can be improved significantly.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described, referring drawings. In addition, the thing of the same structure as a conventional example attaches | subjects the same code | symbol, and abbreviate | omits description. In addition, this invention is not limited by this Example.

(First embodiment)

Fig. 1 is a longitudinal sectional view of the dish washing machine according to the first embodiment of the present invention, and Fig. 2 is a longitudinal sectional view (main part enlarged longitudinal sectional view) of the mist generating means. In FIG. 1, the detergent liquid formation part 13 is formed in the position along one side of the front end of the washing tank 2, obstructs the washing tank 2 and the partition 14, and forms a part of the partition 14. In FIG. It cuts and communicates with the washing tank 2, and arrange | positions the mist generation means 15 for misting the detergent liquid formed in the detergent liquid formation part 13 inside. The mist generation means 15 arrange | positions the ultrasonic vibrator (fog generation vibrator) 16 on the lower surface as shown in FIG. 2, and places the sealing liquid 17 above the vibration surface of this ultrasonic vibrator 16. As shown in FIG. The enclosed container 18 is disposed and faces the ultrasonic vibrator 16 of the container 18, that is, the mist generating surface 19, via a vibration transmitting material composed of the encapsulating liquid 17 and the container 18. ) Is vibrated, and the detergent liquid in the detergent liquid forming unit 13 is misted. In addition, the cover portion 20 is disposed above the detergent liquid forming portion 13, and the cover portion 20 washes the cover portion 21 and the detergent that form the mist-forming surface 19 from above and the detergent forming portion ( It consists of the inclined part 22 introduce | transduced into 13, The cover part 21 is provided with the hole part 23 for scattering the mist liquid which was made into mist.

The operation and action of the dishwasher configured as described above will be described. When a predetermined amount of detergent is put on the inclined portion 22, the detergent is introduced into the detergent liquid forming portion 13 along this slope. Next, when the operation is started, the water supply valve 3 is opened to supply washing water of a predetermined amount of water supply amount. The washing water penetrates into the detergent liquid forming portion 13 through the cutout of the partition 14 from the washing tank 2, and a part of the detergent is dissolved in the washing water. When the ultrasonic vibrator 16 is driven at this point of time, the vibration propagates the encapsulating liquid 17 and vibrates the mist generating surface 19 via the encapsulating liquid 17 and the container 18. At this time, if the position of the mist generating surface 19 is arrange | positioned in the position where the vibration amplitude of the ultrasonic vibrator 16 becomes the maximum, the mist generating surface 19 can be vibrated largely. By this vibration, the washing water 2 is vibrated through the hole 23 while vibrating the washing water on the upper surface, causing the washing water to fog, and simultaneously dissolving the detergent set in the detergent liquid forming portion 13. The high concentration detergent liquid can be scattered into the inside, and the high concentration detergent liquid can be adhered to the object to be cleaned 8.

As a pretreatment step of the washing step, as described above, a high concentration of detergent liquid is scattered from the mist generating means 15 into the washing tank 2, and the high concentration detergent liquid is attached to the object to be cleaned 8, When left in that state, a high concentration of detergent liquid chemically decomposes the contamination adhering to the object to be cleaned 8.

In this washing step after the pretreatment step, cleaning using a conventional dishwasher is performed on the contamination after the specific contamination is decomposed by the high concentration detergent liquid in the pretreatment step.

In the contamination of the to-be-cleaned object 8, temperature and a mechanical force (the intensity | strength of the injection of the washing water from the washing nozzle 7) may be very effective. In addition, even in the case of the contamination which has been decomposed in the pretreatment stroke, the cleaning can not be performed by that much, and the cleaning can be reliably performed by temperature or mechanical force. However, the decomposition of contamination by neglect after adhesion of the high concentration detergent liquid in this pretreatment stroke is very effective for the kind of contamination which could not be removed conventionally.

Since the lid portion 20 of the present invention covers the mist generation surface 19 with the cover portion 21 from above, the detergent added by the user is not directly mounted on the mist generation surface 19, for example. Even when detergent is first put in at the time of reserved driving, detergent is not fixed on the mist generating surface 19, and the mist generating surface 19 can be prevented from dissolving by self-heating, and the inclination part Determination can be surely introduced into the detergent liquid formation part 13 by (22). This makes it possible to stably disperse a detergent concentration of a higher concentration than a predetermined concentration, that is, a detergent concentration in normal use, over a long period of time, and to adhere to the object to be cleaned, and the chemical strength of the high concentration detergent attached to the object to be cleaned. By this and subsequent washing | cleaning process, the dishwasher which greatly improved the washing | cleaning performance can be implement | achieved.

(Second embodiment)

3 is a longitudinal sectional view (main part enlarged longitudinal sectional view) of the mist generating means of the dish washing machine according to the second embodiment of the present invention. In FIG. 3, the cover part 24 is arrange | positioned above the detergent liquid formation part 13, and the agent which introduce | transduces a detergent into the washing | cleaning formation part 13 at the lower end of the inclination part 22 of the cover part 24 is shown. The opening part 25 is provided, and the 2nd opening part 26 is provided in the communicating part of the detergent liquid formation part 13 and the washing tank 2. As shown in FIG. The first opening portion 25 has a lattice shape, and the second opening portion 26 has a rectangular shape, and the short side (width) of the second opening portion 26 is configured to be longer than one side of the first opening portion 25. Moreover, inside the cover part 27 of the cover part 24, a pair of lip 28 is provided in the left and right both sides of the part to which the liquid column which arises when the detergent liquid is made to fog collide, and the cover part The detergent liquid impinged on (27) is recovered by the lip 28 and is configured to return to the detergent liquid forming unit 13. The other structure is the same as that of the said 1st Example, and detailed description is abbreviate | omitted.

The operation and operation of the dish washing machine configured as described above will be described. When a predetermined amount of detergent is put on the inclined portion 22, the detergent is introduced into the detergent liquid forming portion 13 along this slope. Thereafter, by performing the same operation as described in the first embodiment, the detergent solution of high concentration can be scattered in the washing tank 2, and the detergent solution of high concentration can be attached to the object to be cleaned 8. In this washing step after the pretreatment step, cleaning using a conventional dishwasher is performed on the contamination after the specific contamination is decomposed by the high concentration detergent liquid in the pretreatment step.

Since one side of the lattice of the first opening part 25 of the lid part 24 of this invention is shorter than the short side of the 2nd opening part 26, the remainder and the foreign material which passed through the 1st opening part during the washing | cleaning operation must always be removed. 2, since it can pass through the openings, no residue or foreign matter remains in the detergent liquid forming portion 13 including the mist generating surface 19, and the deposition on the mist generating surface 19 is prevented. It is possible to prevent dissolution due to self-heating of the mist-generating surface 19 and to maintain hygiene in the washing machine.

In addition, the concentration of the detergent liquid is obtained by returning the liquid pillar of the detergent generated by the ultrasonic vibration to the inside of the cover portion 27 by the lip 28 provided with the left and right pairs and returning it to the detergent liquid forming portion 13. Since becomes higher, the concentration of the detergent to be misted can be maintained higher. As a result, a higher concentration of detergent liquid can be scattered and adhered to the object to be cleaned. The cleaning performance can be greatly improved against a wider range of contamination, while the inside of the washing machine can be kept hygienic, and the tableware is highly reliable. Washing machine can be realized.

As described above, the dishwasher according to the present invention is provided with a cover portion covering the mist generation surface, thereby preventing the detergent from sticking on the mist generation surface, and dissolving the mist generation surface by self-heating by ultrasonic vibration. It can be prevented, and the detergent concentration of higher concentration than the detergent concentration at the time of normal use can be stably adhered to the to-be-cleaned object, and the cleaning performance greatly improved by the chemical force of the high concentration detergent attached to the to-be-cleaned object. Since it becomes possible, it is useful as a dishwasher etc. which wash | clean by spraying washing water to wash objects, such as tableware.
