  As described above, the present invention provides a menu key for automatic washing that displays cooking details, so that the user can determine the degree of detergent and washing time without having to judge the degree of stains and ingredients of the dishes and cooking utensils. It is possible to prevent waste and perform optimal cleaning.

Embodiment 1 FIG.
1 is a block diagram showing an operation unit of a dishwasher according to Embodiment 1 of the present invention. Here, a dishwasher having a drying function will be described. In the figure, an operation course display section 2 for each cooking content is displayed on the operation section 1, and an operation course display section 2 for each cooking content (the menu key for automatic washing displaying the contents of the cooked food in the claims). ) Is classified as “Western food” 3 / “Japanese food” 4 / “Chinese food” 5 / “Main food” 6. “Western food” 3 of the operation course display section 2 according to the cooking content is “baked food” course 7 / “boiled food” course 8 / “egg” course 9 and “Japanese food” 4 is “baked food” course 10 / “boiled food” course 11 / "Fried" course 12, "Chinese" 5 "baked" course 13 / "Fried" course 14 / "Steamed" course 15, "Food" 6 "Rice rice bowl" course 16 / "Rice rice platter" course 17 / "Bread" course 18 / "Japanese noodle" course 19 / "Western noodle" course 20 are displayed. In addition, the “baked food” 7 of the “Western food” 3 has “steak” “hamburger” and “boiled food” 8 “curry” “stew”, so that the user can judge immediately. “Japanese food” 4 “baked fish” 10 has “baked fish” “teriyaki”, “boiled food” 11 has “meat potatoes” “vegetables”, “fried food” 12 has “fried” “tempura”, “Chinese” 5 Specific menus such as “gyoza” are displayed in “baked food” 13, “happo vegetables”, “sauce pork” in “fried food” 14, and “suimai” in “steamed food” 15. This specific menu can be selected by pressing each display unit. A plurality of menus displayed on the cooking course display section 2 for each cooking content can be selected.

The operation section 1 displays an automatic course 21 corresponding to the case where it is only necessary to control the washing, time, or amount of detergent that is not included in the menu displayed on the cooking course display section 2 according to cooking contents. The entrusted course 21 is classified into three, and “standard course” 22 / “speed course” 23 / “firm course” 24 are displayed. In this Omakase Course 21, regardless of the type (component) and amount of stains on tableware and cooking utensils, if the “Standard Course” 22 time / detergent amount is 1, the “Speed Course” 23 will be the time / detergent amount. Is a driving course that controls the time and amount of detergent to 1.5 times. Also, “30 minutes” 26 / “45 minutes” 27 / “60 minutes” 28 are displayed in the “drying course” 25 for only the drying operation. If you want to automatically perform this drying course after cleaning the driving course selected in the cooking course by cooking content, you can select it by pressing both the menu key for the cooking course and the menu key for the drying course. .

When the menu displayed on the cooking course display section 2 for each cooking content is selected, or when the menu displayed on the Omakase course 21 is selected, the amount of detergent to be added is displayed in the detergent amount instruction diagram 29, and is the lowest. The scale is 1/3 of the standard scale, and the second scale from the bottom is 2/3.

  “Power ON / OFF” 30 is used to turn on / off the dishwasher by pressing, and “START PAUSE” 31 is used to start driving or Also serves as a temporary stop of operation.

  First, each process of the cooking course display section 2 according to cooking contents will be described. FIG. 2 is a diagram showing an example of target preliminary washing water temperature, main washing water temperature, operation time, and detergent amount setting in each step of the cooking course according to cooking contents. In the operation course for washing and drying the dishes and cooking utensils of conventional dishwashers, the cleaning process is about 60 ° C and the final rinse is performed for the purpose of washing high melting point oil and fat stains and sterilizing the objects to be washed. In the process, the temperature of the washing water is raised to a high temperature of about 70 to 80 ° C., and in the drying process, high-temperature air of about 80 ° C. is blown into the washing tank. However, for example, if you eat raw eggs over curry rice, the amount of fat and starch is large, but the eggs are semi-ripe and partially heat-denatured. When it comes in contact, it heats and solidifies, resulting in a problem that it becomes difficult to clean. Moreover, it becomes difficult to wash the eggs after heat denaturation with high-temperature water at 60 ° C. or higher. In the dishwasher of the first embodiment, in addition to the “standard course”, “speed course”, and “firm course” for washing dishes and cooking utensils similar to those in a conventional dishwasher / dryer, an operation course for each cooking content is provided. In particular, in the course in which eggs are selected as a menu, the final target water temperature of the pre-washing temperature before the detergent is added and the main washing temperature after the detergent is added is lowered to prevent heat denaturation and solidification of the egg.

  FIG. 3 is a diagram showing the relationship between the washing temperature and the starch washing effect. The higher the washing temperature, the higher the washing effect at 70 ° C. or higher. For menus with a large amount of starch, Set the temperature higher. FIG. 4 is a diagram showing the relationship between the cleaning temperature and the fat cleaning effect. Since fat also exhibits the effect remarkably at 70 ° C. or higher, the cleaning temperature is set higher for a menu with a large amount of fat. In particular, Chinese food and Japanese deep-fried food use more oil than Western food, so it is better to raise the pre-washing temperature and dissolve the oil with warm water. FIG. 5 is a diagram showing the relationship between the washing temperature and the protein washing effect. However, since the protein is denatured by heat, the washing temperature must be set low. When eggs are selected in the selection menu, the washing temperature, especially the pre-washing temperature, is set to a low value regardless of the amount of starch and fat. When the amount of starch and fat is high and eggs are selected, the cleaning time is extended to cover the decrease in cleaning power due to low temperature. In addition, the detergent amount is set to a large amount because it is necessary to add a large amount when the fat amount and the protein amount are large, and when the amount is small, the detergent is wasted. Thus, as shown in FIG. 2, by setting the pre-wash water temperature / main wash water temperature / operation time / detergent amount of each menu and selecting each menu key, the starch amount, fat amount, protein are automatically set. Since the amount is determined and the optimum washing operation course is selected, the optimum washing can be performed without easy judgment by the user.

  That is, as shown in FIG. 2, in the selection menu “Western baked goods” 7 / “Rice rice bowl” 17, it is judged that starch is normal-fat-rich-protein is low, and pre-wash temperature-time is 60 ° C.-5 minutes. Temperature-time is 70 ° C.-20 minutes, and the amount of detergent is standard (assuming 1). This setting condition is the same for the “standard course”. The standard detergent concentration is, for example, about 0.1%. In addition, “Western simmered food” 8 / “Rice plate platter” 18 is judged to have a high starch content, high fat content, low protein content, pre-wash temperature—time of 60 ° C.-7 minutes, main wash temperature—time of 70 ° C.-20 minutes, The amount of detergent is standard (1). “Western simmered food” 8 / “Rice plate platter” 17 and “egg” 9 are judged to have a high starch content, a high fat content, a high protein content, a lower washing temperature, a longer time, and a prewash temperature of 50 ° C.-10 Minutes, main washing temperature-time is 60 ° C.-30 minutes, and the amount of detergent is standard (assuming 1). "Western food boiled" 8 / "bread" 18 is judged to be low in starch, high in fat, low in protein, pre-wash temperature-time is 60 ° C-3 minutes, main wash temperature-time is 70 ° C-20 minutes, detergent The amount is standard (1). In “Japanese food baked goods” 10 / “Rice rice bowl” 16, it is judged that starch is normal-less fat-less protein, and the washing time is shortened, the prewash temperature-time is 60 ° C-5 minutes, main wash temperature-time is 70 ° C-15 minutes, 2/3 detergent amount. In “Japanese food boiled” 11 / “rice cooked rice bowl” 16 / “egg” 9 it is judged that starch is normal-less fat-more protein, lower washing temperature, longer prewash temperature, prewash temperature-time is 50 ° C -10 minutes, Main washing temperature-Time is 60 ° C-20 minutes, standard amount of detergent. In “Japanese deep-fried food” 12 / “Rice rice bowl” 16, it is judged that the amount of starch is normal-very high in fat-low in protein, the temperature is increased from pre-washing, the washing time is shortened, the amount of detergent is increased, the pre-washing temperature-time Is 70 ° C for 5 minutes, main washing temperature is 70 ° C for 15 minutes, and the amount of detergent is 2/3. “Chinese baked goods” 13 / “Rice rice bowl” 16 and “Chinese fried dishes” 14 / “Rice rice bowl” 16 also have the same operating conditions as “Japanese food fried food” 12 / “Rice rice bowl” 16. In “Chinese steamed food” 15 / “Rice rice bowl 16”, it is judged that the amount of starch is normal-normal fat-less protein, and it is set to be shorter. Pre-wash temperature-time is 60 ° C-5 minutes, main wash temperature-time is 70 ℃-15 minutes, standard amount of detergent for Chinese. “Japanese food fried food” 12 / “Japanese noodles” 19 are judged to have a high starch content, a very high fat content, a low protein content, a high temperature, a pre-wash temperature of 70 ° C. to 5 minutes, and a main wash temperature of 70 hours. ℃ -15 minutes, standard amount of detergent. With only “Japanese noodles” 19, it is judged that the amount of starch is normal-less fat-less protein, the time is shorter, the washing temperature-time is 60 ° C for 5 minutes, the main washing temperature-time is 70 ° C-5 minutes, the amount of detergent is The amount is 2/3. In “Western Noodles” 20, the amount of starch is normal-rich in fat-low in protein, the temperature is set high and the time is set short. Pre-washing temperature-time is 70 ° C-5 minutes, main washing temperature-time is 70 ° C- Standard amount of detergent for 20 minutes. In “Western Noodles” 20 and “Eggs” 9, the amount of starch is normal-rich in fat-protein is judged high, the temperature is set low, the pre-washing temperature-time is 50 ° C-10 minutes, the main washing temperature-time is 60 ℃-15 minutes, standard amount of detergent (1).

  The operation of the cooking course for each cooking content set in this way will be described with reference to the program diagram of FIG. First, when the power is turned on by the power switch 30, the switch itself is turned on, and the driving course displayed on the operation unit 1 can be selected. For example, after selecting the menu “Boiled Western Food” 8 / “Rice Dish” 17 and pressing the start button 31, it is judged that the starch amount is high, the fat amount is high, the protein content is low, and the detergent amount is standard. The amount of detergent is displayed in the quantity instruction diagram 29. The user sets the indicated amount of detergent in the dishwasher, recognizes that it has been set, and then starts pre-washing. In this case, since the time-temperature setting is 60 ° C.-7 minutes, after reaching 60 ° C., preliminary washing is performed for 7 minutes. At this time, no detergent is added. After 7 minutes, the water is drained and main washing begins. At this time, the detergent is put into the dishwasher, and the washing water is raised to 70 ° C., which is the set temperature for the main washing. After reaching, the main washing is performed for 20 minutes, and then the water is drained and rinsed 2 to 3 times. Then, the drying operation is performed, and after completion, the power switch 30 is turned off.

  Next, each process of the automatic course 21 will be described. FIG. 7 is a diagram showing an example of target pre-washing water temperature / main washing water temperature / operation time / detergent amount setting in each process of the Omakase course. "Standard course" 22 is automatically judged to be normal starch amount-normal fat amount-low protein, pre-washing temperature-time is 60 ° C-5 minutes, main washing temperature-time is 70 ° C-20 minutes, detergent The quantity is set as standard. “Speed course” 23 is automatically judged to be low in starch, low in fat, low in protein, pre-washing temperature—time is 60 ° C. for 3 minutes, main washing temperature—time is 70 ° C.—10 minutes, amount of detergent Is set to 2/3 amount. “Sturdy Course” 24 is automatically judged to have a large amount of starch, a large amount of fat, and a large amount of protein. Pre-washing temperature—time is 50 ° C.—15 minutes, main washing temperature—time is 60 ° C.—40 minutes, detergent The quantity is set to 3/2 quantity.

The operation of the Omakase Course set in this way will be described with reference to the program diagram of FIG. First, when the power is turned on by the power switch 30, the switch itself is turned on, and the driving course displayed on the operation unit 1 can be selected. For example, after selecting the “standard course” 22 and pressing the start button 31, it is determined that the starch amount is normal, the fat amount is normal, the protein is low, and the detergent amount is standard. Is displayed. The user sets the indicated amount of detergent in the dishwasher, recognizes that it has been set, and then starts pre-washing. Since the preset temperature of the preliminary washing-time is 60 ° C.-5 minutes, the preliminary washing is performed for 5 minutes after the temperature of the washing water reaches 60 ° C. At this time, no detergent is added. Then, after 5 minutes of pre-washing, the water is drained and the main washing starts. The detergent is put into the dishwasher and the temperature of the wash water rises to 70 ° C. After washing with washing water at 70 ° C. for 20 minutes, it is drained, rinsed 2 to 3 times, a drying operation is performed, and the power switch 30 is turned off after completion.

  In addition, since the stain | pollution | contamination of tableware and a cooking utensil is fully wash | cleaned by this washing | cleaning, you may make it the rinse water temperature to reach | attain 80 degreeC.

  Next, the drying course will be described. When only the drying course is used, the user himself / herself selects the drying time as 30 minutes, 45 minutes, or 60 minutes. When the power is turned on by the power switch 30, the switch itself is turned on, and the “drying course” 25 can be selected. For example, when “30 minutes” 26 is selected and the start button 31 is pressed, the drying operation starts. After 30 minutes, the power is automatically turned off and the power switch 30 is turned off.

In this way, by providing the dishwasher with an operation course according to the cooking content placed on the dishes / cooking utensils, the user ate the menu without having to consider the components (types) of the dishes / cooking utensils. By selecting, it is possible to perform cleaning that is optimal for the menu, that is, the dirt component of tableware and cooking utensils. Further, by selecting a plurality of courses, it is possible to perform optimal cleaning even when dishes and cooking utensils on which menus suitable for low-temperature cleaning such as egg dishes are mounted are cleaned at the same time.

The configuration of the operation unit shown in FIG. 1 is merely an example, and an operation course selection method for selecting an operation course by a dial switch and a selection dedicated switch can be separately provided, and the operation course can be selected every time the operation is performed. The configuration of the operation unit, such as the method, can be changed according to the design of the dishwasher.

  In the first embodiment, the dishwasher has a drying function. However, even a dishwasher having only a washing function without a drying function has the same effect.

Embodiment 2. FIG.
In the dishwasher of the first embodiment, washing is performed using a general detergent, but electrolytic alkaline water may be used instead of the general detergent. The electrolytic alkaline water may be generated inside or outside the dishwasher. FIG. 9 is a configuration diagram of the operation unit of the dishwasher using electrolytic alkaline water, and the operation unit 32 does not have a detergent amount input display. The electrolytic alkaline water cleaning effect is a synergistic effect of PH and salt, but is particularly effective at normal temperatures for proteins. FIG. 10 is a diagram showing the pH value for the cleaning effect on soft-boiled eggs. As shown in the figure, the cleaning effect increases rapidly at pH 11 or higher. The salt concentration at pH 11 is 0.02% and the salt concentration at pH 12 is 0.2%, which is a synergistic effect of pH and salt water. Further, the pH of the electrolytic alkaline water is set to pH 11.5 when the detergent amount in FIG. 2 is a standard, and is set to pH 11 for 2/3 amount and pH 12 for 3/2 amount.
