The dishwasher includes a washing tank for holding objects to be cleaned, such as tableware,

A washing pump for pressurizing the washing water,

Washing means having an injection hole for injecting washing water pressurized by the washing pump;

Detergent liquid scattering means for attaching the detergent liquid of a concentration higher than the washing water sprayed by the washing means to the object to be cleaned,

The washing water sprayed from the washing means dissolves the detergent liquid attached to the object to be washed in a predetermined amount of water supplied to the washing tank to a predetermined concentration.

However, since the conventional dishwasher mists the tap water in which the exclusive detergent is not dissolved, it is possible to obtain a constant swelling effect on the dirt, but it is necessary to improve the cleaning effect on the strong protein dirt or oil dirt. It could not be reached. In addition, in order to further increase the cleaning power, it is necessary to use a separate high concentration detergent in addition to the exclusive detergent.

In the lower part of the washing tank 2, the heater 7 which heats washing water is arrange | positioned.

The detergent injecting container 8 is arrange | positioned under the front surface of the washing tank 2. The top surface of the detergent injecting container 8 is opened, and a cover 9 is provided in the opening so as to be opened and closed. Moreover, the water supply port 10 for supplying washing water to the washing tank 2 is provided in the side surface of the detergent supply container 8. The inside of the detergent injecting container 8 is divided into two upper and lower layers by the filter 11 in which many round holes were formed in the surface. The filter 11 has an opening area suitable for moving to the lower layer 26 as a detergent solution when the powder is dissolved.

The discharge port 14 which communicates with the 1st water supply valve 12 through the dissolution path 13 is provided in the side wall of the upper layer 25 of the detergent input container 8. Detergent is melt | dissolved by the earth output of the washing | cleaning water discharged | emitted from the discharge port 14, it passes through the filter 11, and is stored in the lower layer 26 of the detergent input container 8. The side wall of the lower layer 26 is opened and communicates with the detergent liquid jetting nozzle 15 through the jetting path 19. The flow rate adjusting valve 27 is provided in the jet path 19 to regulate the jet flow rate of the detergent liquid.

In the lower part of the washing tank 2, the scattering nozzle part 16 which scatters a detergent liquid to tableware is arrange | positioned. The flying nozzle part 16 is comprised with the nozzle 15 for detergent liquid jet and the nozzle 18 for air jet. The ejecting direction of the air ejecting nozzle 18 is arranged so as to eject air in a substantially vertical direction with respect to the ejecting direction of the detergent liquid ejecting nozzle 15 and to scatter toward the tableware. The air blowing nozzle 18 ejects the air pressurized by the air pump 17. Moreover, the 2nd water supply valve 20 for supplying water to the washing tank 2 is provided in the jet path 19 which communicates the detergent liquid jet nozzle 15 and the detergent injecting container 8 with each other.

The air pump 17 has a drive source that can change the blow pressure capability of the air, and is controlled together with the cleaning pump 3, the heater 7, the first water supply valve 12, the second water supply valve 20, and the like. Controlled by the device 24. In the dissolution path 13 and the jet path 19, the back flow prevention valves 21 and 22 are provided in the first water supply valve 12 and the second water supply valve 20 so that sewage does not flow back. The scattering nozzle unit 16 is covered with a protective cover 23 for preventing the adhesion of contaminants during dish feeding or washing.

In addition, if a direct current motor is used as the drive source, the blowing pressure capability of the air can be changed by controlling the applied current. In the case of an AC motor, the blowing pressure of air can be changed by controlling the drive frequency of a drive source. Moreover, the detergent liquid scattering means is comprised by the detergent liquid jet nozzle 15, the air pump 17, the air jet nozzle 18, and the control apparatus 24. FIG.

Moreover, the detergent liquid generation means is comprised by the detergent input container 8, the cover 9, the filter 11, the 1st water supply valve 12, the dissolution path 13, and the jet path 19. do. Further, the first water supply valve 12, the discharge port 14, and the control device 24 constitute a concentration adjusting means.                     

The operation and action in the above configuration will be described. First, a pretreatment stroke for attaching a high concentration of detergent liquid to a tableware is performed. In order to produce a high concentration of detergent, the lid 9 provided on the upper part of the detergent injecting container 8 is opened, and a predetermined amount of detergent (powder) is introduced. The detergent is set on the filter 11 installed in the upper layer 25 of the detergent injecting vessel 8. Water supplied from the first water supply valve 12 passes through the dissolution path 13 and is supplied to the upper layer 25 from the discharge port 14 opened on the side surface of the filter 11. At this time, the detergent is dissolved while being mixed with the water flow during water supply, and is stored as the detergent liquid from the round hole provided in the filter 11 to the lower layer 26.

The amount of water supplied to the detergent input container 8 is much smaller than the amount of water normally supplied to the dishwasher, thereby producing a high concentration of detergent liquid. For example, when a predetermined amount is added to the detergent to be added, the amount of water supplied is 1/50 of a normal amount, and a detergent liquid having a concentration of about 50 times can be generated. The first water supply valve 12 is used to generate a high concentration of detergent liquid while dissolving the detergent in a small amount of tap water, and a low flow type one is used.

In addition, about the density | concentration adjustment of detergent liquid, detergent liquid density | concentration is adjusted by changing the amount of detergent supplied to the detergent injecting container 8, and changing the amount of water supplied from the 1st water supply valve 12. As shown in FIG. And the quantity of water put into the detergent input container 8 is divided into several times, and it scatters with respect to utensils every time. In this case, the resulting detergent concentration is gradually diluted, but the dissolution residue of the detergent in the detergent input container 8 may be lost. In particular, since it is difficult to dissolve the detergent when using low temperature tap water, the detergent can be effectively operated by the above method. In addition, since a high concentration of detergent solution is adhered to the contamination, the detergent component can be penetrated more extensively and to a greater detail of the dirt without diminishing the detergent concentration, so that the cleaning agent can be effectively operated.

In addition, the detergent liquid concentration can be adjusted by making the water supply amount supplied from the 1st water supply valve 12 constant, and changing the amount of detergent injected into the detergent injecting container 8. In this case, since the detergent liquid of a higher concentration can be produced, the washing effect obtained becomes larger.

Next, when the air pump 17 is operated, high-speed air is ejected from the air ejecting nozzle 18, and the detergent liquid ejecting nozzle 15 disposed near the air ejecting nozzle 18 in the vertical direction. The inside of the path becomes negative pressure due to the eject effect. Therefore, the high concentration detergent liquid stored in the lower layer 26 of the detergent injecting container 8 is sucked up into the detergent liquid ejecting nozzle 15 through the ejection path 19, and rises. The detergent solution of high concentration is scattered toward the tableware with the air ejected from the air blowing nozzle 18, and adheres to the tableware with the dirt.

Moreover, with such blown air, the detergent liquid can be scattered on the whole tableware by forming the flow of air in the washing tank 2 whole. The particle size of the detergent liquid to be jetted can be changed so that the flow rate of the detergent liquid is optimal by adjusting the flow pressure of the air pump 17 and adjusting the flow rate adjusting valve 27. After the injection of the high concentration detergent liquid, the air pump 17 is stopped, and after that, the high concentration detergent liquid adhered to the soil is infiltrated and swelled and left for a predetermined time so as to further obtain the effect of the detergent.

Next, this washing process is performed. By opening the second water supply valve 20, some of the tap water flows into the lower layer 26 of the detergent inlet container 8, and together with the detergent remaining dissolved on the filter 11, inside the detergent inlet container 8. While rinsing, water is supplied from the water supply port 10 of the upper layer 25 to the washing tank 2. In addition, the remaining tap water is injected into the cleaning tank 2 from the nozzle 15 for spraying the detergent liquid through the jet path 19. In this way, in the water supply step after the pretreatment stroke, the detergent liquid in the jet path 19 and the detergent liquid jet nozzle 15 is thoroughly washed to prevent the detergent component from adhering to the path, thereby maintaining a stable spray of washing water.

Then, after a certain amount of tap water is stored by a water level detection float (not shown), the washing pump 3 is driven to spray the dishes from the washing nozzle 5. In addition, the amount of detergent contained in the washing step is added to the amount of detergent sprayed in the pretreatment stroke in most cases, and the amount of detergent remaining dissolved is also introduced into the washing tank 2 in the first water supply of the washing step. It is washing with washing water.

Then, after the rinsing stroke is performed several times by replacing the washing water in the washing tank 2, a heating rinsing stroke is rinsed with the hot washing water that is warmed up, and the washing process is completed. In addition, the drying process of drying the dish which was wash | cleaned last may be performed.

As a pretreatment stroke of the washing stroke, a high concentration detergent liquid is scattered from the detergent liquid scattering means in the washing tank 2, and the high concentration detergent liquid is attached to the object to be cleaned, and the detergent is concentrated for a certain time. Chemically decomposes the dirt attached to the object to be cleaned. Concentration of this detergent in high concentrations, since surfactants, alkali agents, bleaches, chelating agents, etc., which are the main components of detergents or exclusive detergents, adhere to the dirt at a concentration higher than the conventional concentration, the effect of washing liquid flowing into the interface between the dirt and the tableware The cleaning effect by alkali and the bleaching effect by a bleaching component can be exhibited remarkably. In this cleaning step after the pretreatment stroke, the dirt after being decomposed by a high concentration detergent liquid in the pretreatment stroke is washed with the cleaning liquid having a normal detergent concentration, whereby the dirt of the object to be cleaned can be reliably washed.

As described above, in the present embodiment, the cleaning performance can be significantly improved by having a pretreatment step in which the detergent liquid having a higher concentration is attached to the object to be cleaned than the detergent concentration in normal use by the detergent liquid scattering means. In addition, by using such a high cleaning power, it is possible to wash in a shorter time, or at a lower washing water temperature. Moreover, the dirt which does not fall conventionally can be wash | cleaned.

In addition, the scattering nozzle unit 16 ejects the high-pressure air pressurized by the air pump 17 to atomize the high concentration of the detergent liquid to be ejected, so that the high concentration detergent sufficiently atomized even in the small gap between the dishes. The liquid enters and can be uniformly attached to the dirt adhered to the tableware and even to the bottom of the recess of the dirt surface. Therefore, it can be set as the scattering system with few spray nonuniformity.

In addition, in generating a high concentration detergent liquid, a high detergent performance is obtained by using a predetermined amount of detergent and producing a high concentration detergent liquid by reducing the amount of washing water to be dissolved. Can be.

In addition, by adjusting the flow rate adjusting valve 27 to increase the flow rate of the detergent liquid, and spraying the detergent liquid with a larger particle diameter, the absolute amount of the detergent liquid to be sprayed can be increased, and more detergent liquid can be attached to the dirt. . For this reason, a predetermined cleaning power can be obtained even when the dirt which is hard to fall off or the amount of attached dirt is large.

In addition, it is possible to make a higher concentration of detergent liquid by making it possible to adjust the concentration of the detergent liquid of high concentration, so that dirt which is less likely to fall, such as denatured protein soil (pressed soil) and a large amount of oil soil, can be cleaned. .

In addition, the washing water sprayed from the washing nozzle 5 continues to dissolve after washing the detergent liquid by dissolving the detergent liquid attached to the object to be washed in the predetermined amount of water supplied to the washing tank 2 to a predetermined concentration. In this way, it is possible to easily make the detergent liquid of the washing concentration normally. Therefore, the dirt which floated in the pretreatment process can be wash | cleaned reliably.

In addition, the water supplied to the washing tank is sprayed by the washing nozzle 5, and the detergent liquid attached to the object to be cleaned is dissolved in the water sprayed by the washing nozzle 5. A detergent solution is prepared and sprayed on the dirt to promote the decomposition or dissolution of the dirt, and thereafter, water is added to wash the detergent solution to a predetermined concentration. Therefore, it is possible to realize effective use of the detergent and at the same time to realize the cleaning performance which is dramatically lowered by enabling the cleaning of the dirt which does not normally fall off.

 In addition, in the present embodiment, water is used for atomizing the detergent liquid, adjusting the particle size of the detergent liquid, adjusting the detergent concentration, adjusting the detergent concentration, and using the high concentration detergent liquid for the next step. As for the constitution and method of lowering the concentration of the detergent liquid with the progress of the scattering of the detergent liquid, there is no necessity to carry out at all, and each of them can be independently performed.

(Second embodiment)

3 is a partial cross-sectional view of the cleaning tank 2 showing the specific configurations of the detergent liquid scattering means and the detergent liquid generating means of the dish washing machine according to the second embodiment of the present invention. 4 is a partial sectional view of the detergent liquid scattering means and the detergent liquid generating means of the dish washing machine according to the second embodiment. 5 is a cross-sectional view of the detergent scattering means. As shown in FIG.3 and FIG.4, the detergent liquid production | generation part (detergent liquid generation means) 30 is comprised under the front surface of the washing tank 2 of the dishwasher. The detergent liquid generating unit 30 is formed independently of the cleaning tank 2, and has a misting unit 31 (detergent liquid scattering means) and a detergent placing unit 32 disposed on the upper side of the detergent inlet cover 33. Is covered with). And it communicates with the washing tank 2 through the notch part 34 comprised as the washing tank 2 and the detergent inlet cover 33. As shown in FIG.

In the detergent inlet cover 33, an upper opening 35 for introducing detergent from the outside is provided on an approximately upper surface of the detergent placing unit 32. In addition, the mist-concentrated detergent is scattered into the cleaning tank 2 through the side opening 36 provided on the side of the detergent inlet cover 33. In addition, as shown in FIG. 5, the misting unit 31 seals the liquid 38 and the air 39 in the container 37, and forms the oscillation surface 41 of the ultrasonic oscillator 40 with the liquid 38. The ultrasonic oscillator 40 is disposed on the lower surface of the container 37 in the direction toward the surface of the container 37, and the lid 43 is pressed to seal the packing 44 provided on the ultrasonic oscillator 40. In addition, although the oscillation surface 41 of the ultrasonic oscillator 40 is provided in substantially parallel with respect to the interface (inclined surface) of a container, it is provided so that it may have a slight inclination angle with the water surface of the washing tank 2.

The operation and action in the above configuration will be described. The misting unit 31 of this invention is comprised from the container 37 which enclosed the liquid 38 in the oscillation surface side of the ultrasonic oscillator 40, The ultrasonic oscillator 40 does not directly contact wash water. Therefore, even when the dishwasher is operated, since the washing water does not come into contact with extremely dirty water, the food is not attached to the oscillation surface 41 of the ultrasonic oscillator 40 in a dirty state and is not solidified. In addition, even in the case of using extremely high hardness water such as well water, the inorganic matters do not precipitate and adhere to the oscillation surface of the ultrasonic oscillator 40, so that misting can be stable for a long time.

Next, the operation of the dish washing machine of the present invention will be described. First, a predetermined amount of detergent is put into the detergent placing unit 32. Next, a predetermined amount of washing water is supplied from the water supply valve (not shown). At this time, the control means 24 sets and controls the water supply level so that the washing water is above the interface 42. In addition, the washing water penetrates into the detergent liquid generating unit 30 from the cutout 34, and a part of the detergent is dissolved in the washing water. At this time, when the ultrasonic oscillator 40 is driven, the oscillation propagates the liquid 38 and is transmitted to the washing water through the interface 42. Then, a water column 45 is generated on the surface of the water, and misting is performed from the water column 45.

The generation of the high concentration detergent liquid is performed by dissolving the detergent liquid and suppressing the diffusion of the high concentration detergent liquid to the washing water in the washing tank 2. First, the water column 45 made of the high concentration detergent liquid is collected by the detergent placing unit 32 and the return passage 46 is formed on the inner wall of the detergent inlet cover 33 so that the high concentration detergent liquid does not flow into the cleaning tank 2. ) Is installed. The return passage 46 is formed downward from the top of the detergent inlet cover 33, the cross-section is formed in a substantially "C" shape to enter into a concave shape, the inside is formed so that the high concentration detergent liquid passes through, as shown by the arrow It is.

By this structure, the flow of the water of the high concentration detergent liquid in the detergent liquid production | generation part 30 generate | occur | produces, and it melt | dissolves a detergent quickly. Moreover, the fall of detergent concentration can be prevented. In addition, since the washing water is also heated by energizing the heater 7 simultaneously with the misting operation, the dissolution of the detergent is promoted to increase the detergent concentration. In this way, the concentration of the high concentration detergent liquid increases in concentration of the detergent liquid as the detergent liquid splashes. For this reason, first, a detergent solution having a low concentration is attached to the dirt, and the detergent solution is absorbed into the dirt, and then a detergent solution having a high concentration is attached to the dirt to a high concentration, thereby improving the permeability of the poor-flowing surfactant to the dirt, and thus cleaning performance. To improve.

Moreover, although the high concentration detergent liquid flows out into the washing tank 2 from the notch 34, since the opening area of the notch 34 is minimized, the fall of detergent liquid concentration is minimized. In addition, when the washing water disappears above the interface 42, the generation of mist is naturally stopped and the detergent solution of high concentration is not scattered. Therefore, when the ultrasonic oscillator 40 is being driven, the control means 24 must be used. The feed water valve is controlled so that the washing water is above the interface.

In addition, the efficiency of mist generation is increased by optimizing the distance and relative angle between the interface 42 and the oscillation surface 41 and the distance from the interface 42 to the surface of the water, respectively. In addition, the interface 42 is inclined surface when the bubbles adhere to the inner wall of the interface 42, it is difficult for the vibration of the ultrasonic oscillator 40 to propagate to the interface 42, so that the bubble along the slope To move away from the center of vibration.

In addition, because of the fine particle diameter, the mist-concentrated high-density detergent liquid merely drifts near the water surface without convection to the upper portion of the washing tank 2 as it is. However, in the structure of this invention, washing water is heated by energizing the heater 7 (flow means) simultaneously with misting operation | movement, and air convection by heat generate | occur | produces with temperature rise. Then, the highly concentrated detergent liquid mistified along the rising air flow of the air is filled in the washing tank 2 in every corner, and adheres to the surface of the tableware unevenly. In addition, since the chemical power is further increased by increasing the temperature of the misted high concentration detergent liquid, the cleaning effect is remarkably improved.

The pretreatment stroke of the washing stroke is the same as in the first embodiment, and description is omitted here. As described above, in the present embodiment, the misting unit 31 has a pretreatment stroke 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 be cleaned, thereby greatly improving the cleaning performance. have.

In addition, since the concentration of the detergent liquid is increased as the detergent liquid is scattered, the permeability to the dirt of the surfactant in the detergent whose fluidity becomes worse at higher concentrations can be effectively applied to the washing.

In addition, by providing a flow means for forming a flow of air in the cleaning tank and attaching a high concentration of detergent liquid to the object to be cleaned by the flow means, the dispersed high concentration of detergent particles is more uniform and wider. It is adhered to the surface of, which can increase the amount of adhesion and reduce the adhesion unevenness.

In the present embodiment, distilled water is added as the encapsulating liquid, but any liquid that can propagate vibration such as brine is not particularly problematic. In addition, it is possible to operate even in low temperature environment by using an antifreeze. In addition, although the interface is made of a resin that is easy to vibrate, even if it is made of a metal by the ability of the ultrasonic oscillator, there is no problem as long as oscillation.

In addition, in the present embodiment, the constitution of increasing the concentration of the detergent liquid with the progress of the scattering of the detergent liquid, and the constitution and method of attaching the detergent liquid of high concentration to the object to be cleaned by the flow means, are inevitably performed. There is no, and each can be implemented independently.

According to the above description, this invention provides the washing | cleaning means which has the washing tank which accommodates to-be-cleaned objects, such as tableware, the washing | cleaning pump which pressurizes washing water, the injection means which sprays the washing | cleaning water pressurized by the washing | cleaning pump, and a washing | cleaning means. And a detergent liquid scattering means for attaching the detergent liquid at a higher concentration than the washing water sprayed on the object to be cleaned. In this way, since the detergent liquid which greatly increased the chemical power can be made to act on the dirt adhered to the to-be-cleaned object, a remarkably high cleaning power can be obtained.

In addition, according to the present invention, the detergent liquid scattering means is configured to atomize the detergent liquid and adhere it to the object to be cleaned, so that a high concentration of the detergent liquid sufficiently atomized even in a small gap between the dishes is uniform to the dirt adhered to the tableware. In addition, since it can attach to the bottom of the recessed part of a dirt surface, it can be made into the scattering system which spray-freeness was reduced.

In addition, the present invention constitutes a detergent liquid scattering means so that the particle size of the detergent liquid to be scattered can be adjusted, thereby suppressing spray nonuniformity and attaching more detergent liquid to the dirt, thus preventing dirt and sticking. Even when the amount of dirt is large, a predetermined cleaning power can be obtained.

In addition, the present invention includes a detergent liquid generating means for generating a detergent liquid, and the detergent liquid generating means has a concentration adjusting means capable of adjusting the concentration of the detergent liquid, so that the detergent concentration is appropriately set according to the type or amount of dirt. Thus, dirt that is less likely to fall off can be cleaned.

In addition, the present invention has a small amount of operation because the concentration adjusting means is configured to adjust the detergent concentration by changing the amount of the washing water dissolving a predetermined amount of detergent, so that a high concentration of detergent liquid can be generated using a predetermined amount of detergent. High cleaning performance can be obtained while maintaining cost.

In addition, the present invention configures the detergent liquid generating means to change the concentration of the detergent liquid and scatter it from the detergent liquid generating means, so that even when the kind, the degree of severity, or the amount of the dirt differ, the detergent liquid having the detergent concentration according to the detergent liquid is produced. Spraying at the optimum concentration can achieve the desired cleaning power.

In addition, according to the present invention, the detergent liquid generating means is configured so that the concentration of the detergent liquid becomes dim as the detergent liquid is scattered, so that a high concentration of the detergent liquid is first attached to the dirt, and the concentration is gradually lowered. Because the components can penetrate into a wider range of dirt and to more detail, high cleaning performance can be obtained without staining.

In addition, the present invention constitutes a detergent liquid generating means such that the concentration of the detergent liquid is increased as the detergent liquid is scattered, thereby increasing the permeability of the surface-active component, which becomes poor in fluidity at higher concentrations, and effectively acts on cleaning. You can.

In addition, the present invention is provided with a flow means for forming a flow of air in the cleaning tank, and by the flow means to attach a high concentration of detergent liquid to the object to be cleaned, the high concentration of detergent particles scattered dishware complex shape Since it can attach more uniformly to the surface of, the cleaning nonuniformity resulting from adhesion nonuniformity can be reduced.

In addition, the present invention is a washing tank for holding the object to be cleaned, such as tableware, a washing pump for pressurizing the washing water, a washing means for spraying the washing water pressurized by the washing pump, and spraying by the washing means A detergent liquid scattering means for attaching a detergent liquid having a concentration higher than that of the washing water to the object to be cleaned, and the washing water sprayed from the washing means dissolves the detergent liquid attached to the object to be cleaned in a predetermined amount of water supplied to the washing tank. By making it become a predetermined density | concentration, since the detergent liquid of normal washing | cleaning density can be made easy even after spraying of detergent liquid, the dirt which floated at the pretreatment process can be reliably cleaned.

In addition, the present invention is to spray the water supplied to the cleaning tank by the cleaning means, so that the detergent liquid attached to the object to be cleaned is dissolved in the water sprayed by the cleaning means, so that only one type of detergent is used for high concentration of detergent liquid. By spraying contaminants, the decomposition and dissolution of dirt can be promoted, and afterwards, the detergent can be washed with a detergent solution of a predetermined concentration, thereby enabling effective use of the detergent and cleaning of dirt that normally does not fall. As a result, it is possible to realize a significantly higher cleaning performance at a lower cost.

As is clear from the above description, the dishwasher of the present invention can realize a dishwasher with a drastic improvement in cleaning power.
