  1st invention has a dishwasher main body, a washing tank which has an opening part in the upper part, accommodates to-be-washed objects, such as tableware, can be pulled out from the said dishwasher main body in a substantially horizontal direction, and pressurizes washing water Cleaning means having a cleaning pump, an injection port for injecting cleaning water pressurized by the cleaning pump, and detergent liquid splashing for adhering a detergent liquid having a higher concentration than the cleaning water injected by the cleaning means to the object to be cleaned By providing the means, it is possible to cause the detergent solution having a greatly increased chemical power to act on the contamination adhering to the object to be cleaned, so that a remarkably high cleaning power can be obtained.

  According to a second aspect of the present invention, in the first aspect, a lid for opening and closing the opening of the cleaning tank is provided, and the detergent liquid can be scattered by the detergent liquid scattering means when the opening is closed by the lid. As a result, when the detergent liquid atomized into the main body is pulled out from the opening of the cleaning tank, the detergent liquid filled in the cleaning tank leaks out of the cleaning tank together with the detergent liquid scattered from the detergent liquid scattering means. I do not put out.

  According to a third invention, in the first and second inventions, the detergent liquid scattering means includes a storage part for storing the detergent liquid to be scattered and a scattering part for scattering the detergent liquid of high concentration. Since the detergent can be dissolved in the reservoir to generate the detergent liquid, a high concentration detergent liquid can be generated and scattered.

FIG. 4 is a partial perspective view of the detergent scattering means. As shown in FIGS. 1 to 4, the main body 1 of the dishwasher is provided with an opening 2 (main body opening) in the front, and the opening 2 can be closed by a front panel 4 of a washing tank 3. . A cleaning nozzle 8 (cleaning means) having an injection port 7 for spraying the cleaning water pressurized by the cleaning pump 6 is provided below the cleaning tank 3 having the opening 5 (cleaning tank opening) above.

  A table basket 9 for storing tableware to be cleaned is provided above the cleaning nozzle 8. A heater 10 for heating the cleaning water is disposed at the lower part of the cleaning tank 3. A roller 11 is disposed on the side wall of the cleaning tank 3, and a guide rail 12 is disposed on the inner wall of the main body 1, and the cleaning tank 3 is supported so that it can be pulled out in a substantially horizontal direction with respect to the main body 1. ing. In addition, a lid 13 covering the opening 5 of the cleaning tank 3 is provided on the upper part of the cleaning tank 3 so as to be movable in a substantially vertical direction with respect to the main body 1. When it is moved and stored in the main body 1, it moves downward. In addition, the sealing part 14 is provided around the cover body 13, and it has the structure which water seals between the washing tanks 3. FIG.

  Reference numeral 15 denotes a water supply valve for supplying cleaning water to the cleaning tank 3. A control device 16 is provided inside the front panel 4 and controls the cleaning pump 6, the heater 10, and the like. A recess 17 recessed outward is provided on the inner wall surface below the front surface of the cleaning tank 3, and the detergent liquid scattering means 18 is disposed in the recess 17. The detergent liquid splashing means 18 includes a splash part 19 for splashing the detergent liquid and a storage part 20 for storing the detergent liquid, and the upper part is covered with a detergent container cover 21. The reservoir 20 is provided with a detergent inlet 22 at the lower part of the front side wall surface of the cleaning tank 3. The scattering unit 19 and the storage unit 20 are formed as a tank independent of the cleaning tank 3, and the cleaning water communicates with the cleaning tank 3 through a notch 24 constituted by the cleaning tank 3 and the detergent container cover 21. In addition, the atomized high-concentration detergent is scattered in the cleaning tank 3 through the side opening 25 provided on the side surface of the detergent container cover 21.

  The scattering unit 19 encloses the liquid 27 and the air 28 in the container 26, arranges the oscillation surface 30 of the ultrasonic oscillator 29 on the lower surface of the container 26 in a direction facing the liquid 27, and the ultrasonic oscillator 29 with the lid 31. The packing 32 attached to is pressed and water sealed. Further, the oscillating surface 30 of the ultrasonic oscillator 29 is provided substantially parallel to the interface 33 (inclined surface) of the container 26, but is installed at a slight angle with the water surface of the cleaning tank 3.

  The operation and action of the above configuration will be described. First, a pretreatment step for attaching a high concentration detergent solution to the tableware is performed. The scattering unit 19 of the present invention is composed of a container 26 in which a liquid 27 is sealed on the oscillation surface side of the ultrasonic oscillator 29, and the ultrasonic oscillator 29 is not in direct contact with cleaning water. Therefore, even when the dishwasher is operated, since it does not come into contact with very dirty washing water, the food does not become sludge and adheres to the oscillation surface 30 of the ultrasonic oscillator 29 and does not solidify. Further, even when water with very high hardness such as well water is used, the inorganic component does not precipitate and adhere to the oscillation surface 30 of the ultrasonic oscillator 29, and the atomization is stably performed over a long period of time. be able to.

  Next, the operation of the dishwasher of the present invention will be described. First, the washing tank 3 is pulled out from the main body, and a predetermined amount of detergent 36 (preferably dedicated detergent) is put into the storage unit 20 from the detergent inlet 22. Next, a predetermined amount of washing water is supplied from the water supply valve 15. At this time, the cleaning water is supplied by the control device 16 so as to be above the interface 33. At this time, the washing water enters the scattering part 19 and the storage part 20 from the notch part 24 as well as the washing tank 3, and a part of the detergent starts to dissolve in the washing water. At this time, when the ultrasonic oscillator 29 is driven, the oscillation propagates through the liquid 27 and is transmitted to the cleaning water through the interface 33. Then, a water column 34 is generated on the water surface, and the high concentration detergent solution is atomized from the water column 34.

  The high-concentration detergent liquid is generated by dissolving the detergent liquid and suppressing the diffusion of the high-concentration detergent liquid into the cleaning water in the cleaning tank 3. First, regarding the concentration, for example, when the water storage volume of the scattering unit 19 and the storage unit 20 is set to 1/50 of the amount of water supplied to the entire cleaning tank 3, and a predetermined amount of detergent is added, theoretically, About 50 times the concentration of detergent solution can be produced. However, since it is connected to the inside of the cleaning tank 3 by the notch 24, the concentration of the detergent solution is slightly reduced by diffusion into the detergent solution. Therefore, in order to suppress the decrease in the concentration, a return passage 35 is provided on the inner wall of the detergent container cover 21 so that the water column 34 made of the high-concentration detergent solution does not flow directly into the washing tub 3 to store the high-concentration detergent solution. Collected in part 20.

  With this configuration, a water flow of high-concentration detergent solution is generated between the scattering unit 19 and the storage unit 20 to prevent a decrease in the concentration of the detergent solution and accelerate the dissolution of the detergent 36. Further, when the heater 10 is energized simultaneously with the atomization operation, the washing water is also heated, so that the detergent is dissolved and the detergent liquid concentration is further increased. As described above, the concentration of the high-concentration detergent liquid is such that the concentration of the detergent liquid increases as the detergent liquid scatters. For this reason, firstly, a detergent solution with a low concentration is attached to the contamination, and the detergent solution is adapted to the dirt, and then a detergent solution with a high concentration is attached to the contamination. It increases the permeability of the active agent to contamination and improves the cleaning performance.

  Although the high-concentration detergent liquid flows out into the cleaning tank 3 from the notch 24, since the opening area of the notch 24 is minimized, the decrease in the detergent concentration is minimized. In addition, when there is no washing water above the interface 33, the generation of atomization stops and the high-concentration detergent liquid does not scatter, so that the washing water always exists above the interface 33 when the ultrasonic oscillator 29 is driven. Thus, the control device 16 controls the water supply valve 15. Note that the mist generation efficiency is increased by optimizing the distance and relative angle between the interface 33 and the oscillation surface 30 and the distance from the interface 33 to the water surface. In addition, the interface 33 has an inclined surface. When bubbles are attached to the inner wall of the interface 33, it is difficult for the vibration of the ultrasonic oscillator 29 to propagate to the interface 33, so that the bubbles move along the inclined surface. This is for shifting from the center of vibration.

  Further, since the high-concentration detergent liquid atomized by the ultrasonic oscillator 29 has a fine particle size of about 0.3 microns, the convection does not flow up to the upper part of the cleaning tank 3 as it is, and it just floats near the water surface. is there. However, in the configuration of the present invention, since the heater 10 (flow means) is energized simultaneously with the atomization operation, the cleaning water is heated, and air convection is generated by the heat accompanying the temperature rise. And the high concentration detergent liquid atomized by the convection effect of air fills up the inside of the washing tank 3 and adheres uniformly to the surface of the tableware. Further, the chemical effect is further increased by increasing the temperature of the atomized high-concentration detergent solution, so that the cleaning effect is dramatically improved.

  In this way, the detergent solution of high concentration adhering to the contamination of the tableware permeates and swells, and is left for a certain period of time so that the effect of the detergent can be further obtained.

  Next, a main washing process is performed in which the washing pump 6 is driven and sprayed from the washing nozzle 8 onto the tableware. In the main washing process, in addition to the amount sprayed on the tableware and the like in the pretreatment process, the detergent solution remaining in the storage unit 19 and the scattering unit 20 also diffuses into the washing tank 3, so that the washing water having a normal detergent concentration is used. Wash with.

  And after performing the rinse process of several times which replaced the wash water of the washing tank 3, the rinse process is completed with the heating rinse process with the high temperature wash water heated at the end. Moreover, the drying process which dries the tableware cleaned at the end may be performed.

  In order to increase the concentration of this detergent, surfactants, alkali agents, bleaching agents, chelating agents, etc., which are the main components of the detergent, adhere to contamination more than the conventional concentration. The effect of facilitating the entry of water, the effect of washing with an alkali, and the effect of bleaching with a bleaching component can be drastically exhibited. And in the main cleaning process after the pretreatment process, the dirt after the specific dirt is decomposed with the high concentration detergent solution in the pretreatment process is washed with a cleaning liquid having a normal detergent concentration. Can be washed reliably.

  Thus, in the present embodiment, the cleaning performance is greatly improved by having a pretreatment step in which a detergent solution having a higher concentration than that of normal use is attached to the object to be cleaned by the detergent scattering means 18 and left to stand. Can be improved. Moreover, it can wash | clean in a shorter time using this high detergency, and it can wash | clean with a lower washing water temperature. In addition, it is possible to clean dirt that could not be removed in the past.

  Moreover, in the dishwasher which draws out the washing tank 3 from the main body 1 opening 2 and puts in and out the tableware, when the lid 13 covering the opening 5 is opened when the washing tank 3 is filled with the high-concentration detergent liquid, the detergent All of the liquid comes out of the cleaning tank 3 and the cleaning performance is greatly impaired. According to the configuration of the present invention, since the cleaning tank 3 has the opening 5 above, even when the cleaning tank 3 is opened during the process of splashing the detergent solution, such as when adding tableware, cleaning is performed. The high-concentration detergent liquid filled in the tank 3 does not leak out of the cleaning tank 3 and can maintain a high cleaning power by the high-concentration detergent liquid.

  In addition, although the present Example demonstrated the method performed by atomizing using an ultrasonic oscillator for the dispersion | distribution of a high concentration detergent, a high concentration detergent is produced | generated previously and the liquid is used as a high pressure pump or an air pump. A method of spraying on tableware using a spraying means such as the above is also conceivable.

  In addition, since the detergent first introduced, including the detergent solution in the pretreatment process, is used in the subsequent main washing process, if the amount of detergent decreases in the middle, the cleaning performance will deteriorate, but the opening When the cleaning tank 3 is pulled out by providing the lid 13 that opens and closes 5 and configured to allow the detergent liquid to be scattered by the detergent liquid scattering means 18 when the opening 5 is closed by the lid 13. The detergent liquid filled in the washing tank 3 with the atomized detergent liquid does not leak out of the washing tank together with the detergent liquid scattered from the detergent liquid scattering means 18.

  Moreover, the detergent liquid scattering means 18 includes the storage part 20 for storing the detergent liquid to be scattered and the scattering part 19 for scattering the detergent liquid of high concentration, so that the detergent is dissolved in the storage part 20 while dissolving the detergent. Since a liquid can be produced | generated, a highly concentrated detergent liquid can be scattered.

  Moreover, the recessed part 17 recessed outside was provided in the inner wall surface of the washing tank 3, and the height (tableware) from the tableware basket 9 to the lid body 13 was accommodated in the recessed part 17 by accommodating at least a part of the detergent liquid scattering means. The detergent liquid scattering means 18 can be configured without reducing the (accommodating height). For this reason, high cleaning performance can be obtained without impairing the storage of tall dishes such as cups.

  In addition, an opening 2 is provided in front of the main body 1 of the dishwasher, and the opening 2 is configured to be closed by a front panel of the washing tub 3, and a detergent liquid scattering means is disposed on or near the front panel of the washing tub 3. Since at least a part of 18 is provided, the tableware storage area is not reduced. Therefore, it can be set as the dishwasher which can obtain high washing performance with the tableware capacity as it is.

  In addition, by disposing the storage unit 20 into which the detergent is placed in front of the main body 1, the detergent can be easily put in, and a dishwasher that is easy to use can be provided.

  Moreover, since the detergent liquid scattering means 18 atomizes and atomizes the high-concentration detergent liquid using an ultrasonic oscillator, the high-concentration detergent liquid can sufficiently enter the slight gap between the dishes. it can. Moreover, it can be made to adhere uniformly to the bottom of the concave portion on the dirt surface even with dirt attached to the tableware.

  Further, by providing a flow means for creating an air flow in the cleaning tank 3 and having the detergent liquid adhere to the object to be cleaned by the flow means, the scattered high-concentration detergent particles have a complicated shape. Therefore, uneven adhesion can be reduced.

  Further, by providing a flow means for creating a flow of air in the cleaning tank, and a structure in which a high-concentration detergent liquid is adhered to the object to be cleaned by the flow means, the scattered high-concentration detergent particles are more uniform. It can be adhered to the surface of tableware over a wide range, and the amount of adhesion and adhesion unevenness can be reduced.

  In the present embodiment, the convection of air is caused by a heater so that a high-concentration detergent solution is uniformly attached to the tableware. However, the air in the washing tub 3 is circulated using a blower. A method is also conceivable in which an air flow is caused in the cleaning tank 3 to be uniformly scattered.

  Further, water supplied to the cleaning tank 3 is sprayed by the cleaning nozzle 8, and the detergent liquid adhering to the object to be cleaned is dissolved in the water sprayed by the cleaning nozzle 8, so that a high concentration can be obtained from one type of detergent. A detergent solution is made and sprayed on the contaminants to promote the decomposition and dissolution of dirt, and after that, the detergent solution is washed to a predetermined concentration by adding water. Therefore, it is possible to realize a drastically high cleaning performance at a low cost, such as making it possible to clean dirt that cannot normally be removed.

  Further, the cleaning water sprayed from the cleaning nozzle 8 is sprayed with the detergent liquid by dissolving the detergent liquid adhering to the object to be cleaned in a predetermined amount of water supplied to the cleaning tank 3 so as to have a predetermined concentration. Since the detergent solution having the normal washing concentration can be easily made subsequently, the dirt floating in the pretreatment process can be surely washed. Moreover, high cleaning performance can be obtained with a small amount of use due to effective use of the detergent.

  In this embodiment, distilled water is used as the sealed liquid, but any other liquid that can propagate vibration such as salt water may be used. Furthermore, by using antifreeze, it is possible to operate even in a low temperature environment. Further, although the interface 33 is made of a resin that easily vibrates, there is no problem as long as it oscillates even if it is made of metal due to the ability of the ultrasonic oscillator.

  In the present embodiment, the lid 13 closes the opening 5 of the cleaning tank 3 and scatters when the opening 5 is closed, and the detergent liquid scattering means 18 includes the water storage unit 20 and the scattering unit 19. The cleaning tank 3 is provided with a recess 17 to accommodate at least a part of the detergent liquid splashing means 18, the detergent liquid is atomized, and the high-concentration detergent liquid is cleaned by the flow means. The structure that attaches to the object, the structure that uses a high-concentration detergent solution for the next process, and the structure that uses a predetermined amount of detergent in the main washing process are not necessarily integrated, and can be performed independently. It is.

  As described above, the dishwasher according to the present invention performs normal washing after spraying a high-concentration detergent solution on an object to be washed such as dishware in advance, and a dishwasher that can obtain a remarkably high washing performance. Useful as.
