201143698 六、發明說明： t發明所厲技冬好領域3 技術領域 本發明係有關於一種進行餐具之洗淨的餐具清洗機。 L先前技術3 背景技術 迄今，該種餐具清洗機係被構成為如第4圖所示者。以 下，針對其結構進行說明。 如第4圖所示，餐具籃2係被配置於洗淨槽1内，且餐具 類3收納於餐具籃2中。從作為供水部之供水閥4供給洗淨 水，並貯存於洗淨槽1中。作為洗淨部之洗淨喷嘴5係在洗 淨槽1内以可自由轉動的方式被支稱，並朝向食器類3喷出 洗淨水。所喷出的洗淨水進入洗淨槽1底面的排水口 6，藉 由洗淨泵7饋入洗淨喷嘴5，並再度被喷出。洗淨泵7及排出 洗淨水的排水泵8係依起被設於洗淨槽的下部。水位檢測部 9係檢測洗淨槽1内的水位是否達到預定水位者，根據浮標 9a的動態來檢測水位。加熱器10係配設於洗淨槽1的底部， 加熱洗淨水者。洗淨槽1底部的外壁設有檢測洗淨溫度的熱 敏電阻11。又，控制洗淨泵7、排水泵8、水位檢測部9、加 熱器10、熱敏電阻11等的控制部12及操作部13、顯示運轉 狀況的顯示部14、生成控制部12等的電源之電源回路15亦 設置於本體。又，用於餐具類3等被洗淨物之洗淨及沖洗的 液體稱為洗淨水。 說明在上述結構中之動作，即，使用者將髒污的餐具 201143698 類3收容於餐具籃2中，並將洗劑投入洗淨槽丨内， 稍1 宗邵 13開始運轉。於洗淨步驟中’由供水閥4供給自來水至先淨 槽1之底部水位檢測部9檢測出已達預定水位為止，若達到 預定水位，則對洗淨泵7及加熱器10通電。又，自來水的供 水係使用分歧龍頭16等從水龍頭開始分歧來進行。洗'淨水 一邊加熱’一邊藉由洗淨泵7自洗淨噴嘴5向餐具類3喷出， 將附著於餐具類3之髒汙移除。此時，藉由熱敏電阻丨丨來檢 測控制洗淨水的溫度。預定的運轉一結束’便對排水栗8通 電，並隨即將含有原附著於餐具類3之髒汙的洗淨水排出。 接著，開始重新供給自來水之沖洗步驟。反複進行不對加 熱器10通電而以水沖洗數次的沖洗步驟，及對加熱器1〇通 電後以熱水沖洗之加熱沖洗步驟’將附著於餐具類3之洗劑 成分髒污等移除。 然而，就上述習知的餐具洗淨機之結構而言，在移除 餐具類的髒汙之洗淨步驟中’因洗劑與附著於餐具類之髒 污的影響而在洗淨水中產生泡沫，洗淨步驟結束，將洗淨 水排水後，在水位檢測部之浮標内及内部的排水口會有泡 沫殘留。此時，在利用浮標之上下動態來檢測水位之水位 檢測部，由於洗淨水上漂浮之泡沫的影響，浮標之移動受 到阻礙。又，由於排出含有泡沫的洗淨水，因此亦會對排 水泵的能力造成影響，無法完全排水而使洗淨層内殘留的 殘水變多。因此，在其後之沖洗步驟中，在供水進行到預 定量之前，浮標便檢測到浮在洗淨水上的泡沫而誤檢出「以 達預定水位」，使得供水量變得較洗淨等所必需之水量少。 201143698 '因此由於難以正確地檢測水量，為了可一定確保洗淨 或’t洗所Μ之水量，在利用浮標之水位檢測後，設置繼 續預疋時間之補給水的時間。而且’考慮到殘水量及泡沐 &成之决差，採取較長之補給水的時間。緣此之故，會有 耗費多餘水量之課題。 [習知技術文獻] [專利文獻] [專和文獻1]日本特開·U7957號公報 【明内】 發明概要

以下，針對本發明的實施形態，參照第1〜3圖來說明。 將餐具籃2以可移動的方式配置於洗淨槽1内，而餐具 類3係收納於餐具籃2中。藉由作為供水部之供水閥4的驅動 來供給洗淨水，並儲存於洗淨槽1中。作為洗淨部之洗淨喷 嘴5係以可自由旋轉的方式支撐於洗淨槽1内的底面，且一 邊旋轉一邊向餐具類3喷出洗淨水。所喷出的洗淨水將進入 洗淨槽1底面的排水口 6，以洗淨泵7加壓洗淨水並將其送至 洗淨喷嘴5，再由洗淨喷嘴5喷出洗淨水。洗淨泵7係與排出 201143698 洗淨水的排水栗8-起配置於洗淨槽丨之底面外壁。水位檢 測部9係檢測洗淨槽1内之水位是否有達到預定义彳者 乂 藉由浮標9a之上下移動來檢測水位。再去 ' ，水位檢測部9亦 可為由-對的電極所構成，以其電極通電時可檢測水位的 方式構成者。 加熱器10係配設於洗淨槽1的底部，且為加熱洗淨水 者。在洗淨槽1之底部的外壁，設有熱敏電阻丨丨，係透過壁 面檢測洗淨水及空氣的溫度者。又’控制部12與電源回路 15亦設置於本體；控制部12係控制洗淨泵7、排水泵8及加 熱器10等，且接受來自水位檢測部9及熱敏電阻丨丨等之信號 者；電源回路15係產生操作部13、顯示運轉狀況之顯示部 14及控制部12等的電源者。又，將用於餐具類3或筷子等被 洗淨物之洗淨及沖洗之液體總稱為洗淨水。 本發明之實施形態的水位檢測部9係藉由連通管外之 水路與洗淨槽1連結，而設置於洗淨槽丨之側面外壁。水位 檢測部9係構成為視浮標9 a之上下動的移動來啟動/關閉 (ON-OFF)微開關 9c。 又，進行水位檢測的控制程式係以如下的方式構成。 藉由作為供水部之供水閥4的動作，對洗淨槽1内進行供 水。控制洗淨泵7、排水泵8及屬加熱部的加熱器1〇之控制 部12係接受來自水位檢測部9的信號，來測定從藉由供水閥 4開始供水至水位檢測部9檢測水位為止的供水時間。又， 控制部12係以下述方式進行控制：在水位檢測部9檢測水 位後，僅在預定時間内繼續進行補給水。又，控制部12進 201143698 一步以下述方式進行控制：當洗淨步驟與沖洗步驟之供水 時間的差在第1判定時間與第2判定時間之内時，僅以較第1 預定時間短的第2預定時間進行補給水。且，以下述方式進 行控制：洗淨步驟與沖洗步驟之供水時間的差，亦即，從 洗淨步驟之供水時間減去沖洗步驟之供水時間所得之值， 若在第1判定時間以上或在第2判定時間以下時，僅以第1預 定時間來進行補給水。在本實施形態中，補給水的預定時 間係假設有泡沫產生之影響的情況下的時間，供水時間差 係設為從洗淨步驟的供水時間減去沖洗步驟的供水時間所 得之值，且令第1判定時間為正的數值，第2判定時間為負 的數值。 說明上述的動作。當餐具清洗機開始運轉，控制部12 進行控制以使供水閥4打開，供給自來水至洗淨槽1的底部 作為洗淨水。由於水位檢測部9與洗淨槽1係藉由連通管9b 連通，因此自來水也同時供給至水位檢測部9内。若進行供 水步驟則水位檢測部9内的水位上升，浮標9a浮起而使微開 關9c的開關啟動/關閉而檢測預定的水位。在此，僅在第1 預定時間進行補給水。供水結束後，關閉供水閥4，洗淨步 驟開始。在該洗淨步驟中，將溶解有洗劑之洗淨水以洗淨 泵7加壓而使其循環。此時，也因為附著於餐具類3之髒汙 的影響，而有起泡的情形。在洗淨步驟結束後將含有泡沫 的洗淨水排水時，泡珠聚集在排水口 6，而降低了洗淨水流 入的速度。又，含有泡泳的洗淨水亦會使排水杲8的吐出能 力降低。這是因為在排水泵8中，雖然在沒有泡沫的部分將 201143698 洗淨水加壓而排水情況下的液體流速快，但在將泡沫部分 加壓而排水的情況中泡沐的流速慢之故。 排水泵8的控制，係在以使其在預定時間動作的方式程 式化的情況中，即使令受到泡沫影響的排水泵8在預定時間 動作，殘留在洗淨槽1中洗淨水的量仍會產生偏差。又’由 於含有泡沫的洗淨水夼會通過連通管9b進入水位檢測部9 内，故在洗淨水排水後泡沫也會殘留在水位檢測部9内。因 此，在下一個步驟的沖洗步驟中，由於在洗淨槽1中殘留有 較多的洗淨水，因此即便進行供水至水位檢測部9會動作的 預定水位，重新供水的供水絕對量仍會變少。又，由於水 位檢測部9内殘留之泡沫的影響，浮標9a會誤檢測到漂浮於 洗淨水上之泡沫，而在洗淨水達到預定的水位前就錯誤地 測得洗淨水已達預定水位。由於該等影響，在有泡沫的情 況中至水位檢測為止的供水時間將比無泡沫的情況早，因 此可藉由測定供水時間來判定是否有泡沬產生的情形。亦 即，洗淨步驟與沖洗步驟之供水時間差為正值時，便為有 泡沫產生的結果。沒有產生泡沫的情況，由於供水時間與 基準值相同’因此供水時間不會有變化。 緣此，若將水位檢測後的補給水時間，在泡沫造成影 響的情況中設為第丨預定時間，而在沒有泡沫影響的情況中 設為較第1預定時間短的第2預定時間，則可在不供給過量 的水里之情況下結束。亦即，可實現節水，且由於不需要 以加熱器10加熱過量的洗淨水，因此亦可實現節能。 然而，若將供水時間差為正值的情況都判斷為有泡沫 201143698 產生，則在實際使用狀態下，即便沒有泡沫的產生，仍有 可能誤判為有泡沫產生。究其原因，在餐具清洗機的供水 過程中，若在餐具清洗機的附近其他的自來水道有機器使 用而進行供水，則會對自來水壓產生變動。又，因髒汙蓄 積於水位檢測部9的浮標9a而使浮力有所變化，或因供水閥 4的動作差異等的各種差異，供水時間將會變動。緣此之 故，可藉由下述判定來修正差異原因，而能精確地進行供 水時間差的判定，即，使沒有泡沫產生之影響的時間維持 在第2判定時間以上、第1判定時間以下的幅度，而將有泡 沫產生之影響的時間設定為第1判定時間以上來進行判 定。藉由將依據該供水時間差所判定的值，設為不僅限於 零，也可在第1判定時間與第2判定時間内，藉此亦可有效 判斷少量泡沫的產生。究其原因，有泡沫的產生，則即便 無法確保預定的供水量，只要是不會對洗淨泵7的動作造成 影響的供水量，則由於不需要減少補給水時間，亦可對應 於此種判定。因此，供水時間的差為第1判定時間之正的數 值以上時，可精準地判定有泡沫產生的影響。 又，當供水時間差在第2判定時間之負的數值以下時， 一般認為供水時間差將因為一些原因而無法正確地判定。 例如，有因為在沖水步驟的供水途中遭到暫時停止等理 由，而無法正確測定供水時間本身等的情況。而在泡產生 在洗淨步驟的情況中，雖然在接下來的沖洗步驟中供水時 間變短，然而若在運轉途中暫時停止則供水時間反而會變 長。其結果，供水時間差為負數、而絕對值大的數值。緣 10 201143698 此之故，雜情況下，設為無衫u供水時間以 沫影響的情況同樣的方式，將供水時間定為第丄預定時^ 則亦可防止因誤檢測而造成之料性能低下。相反地 供水步驟的途中遭到暫時停止的情況中，就供水時間差而

Description of the Invention: The invention relates to a dishwasher for washing dishes. L Prior Art 3 Background Art Heretofore, such a dishwasher has been constructed as shown in Fig. 4. The structure is explained below. As shown in Fig. 4, the cutlery basket 2 is placed in the washing tub 1, and the dishes 3 are housed in the cutlery basket 2. The washing water is supplied from the water supply valve 4 as the water supply unit, and is stored in the washing tank 1. The washing nozzle 5 as the washing unit is rotatably supported in the washing tank 1, and discharges the washing water toward the food unit 3. The discharged washing water enters the drain port 6 on the bottom surface of the washing tank 1, and is fed into the washing nozzle 5 by the washing pump 7, and is again discharged. The washing pump 7 and the drain pump 8 for discharging the washing water are provided in the lower portion of the washing tank. The water level detecting unit 9 detects whether or not the water level in the washing tank 1 has reached a predetermined water level, and detects the water level based on the dynamics of the buoy 9a. The heater 10 is disposed at the bottom of the washing tank 1 to heat the washing water. The outer wall of the bottom of the washing tank 1 is provided with a thermistor 11 for detecting the washing temperature. Further, the control unit 12 and the operation unit 13 such as the cleaning pump 7, the drain pump 8, the water level detecting unit 9, the heater 10, and the thermistor 11, and the power supply unit such as the display unit 14 for displaying the operation state and the control unit 12 are controlled. The power circuit 15 is also disposed on the body. Further, the liquid used for washing and rinsing the washed matter such as the tableware 3 is called washing water. In the above configuration, the user puts the dirty tableware 201143698 class 3 in the cutlery basket 2, and puts the lotion into the washing tank, and a little Shao 13 starts to operate. In the washing step, the bottom water level detecting unit 9 that supplies the tap water from the water supply valve 4 to the first clean tank 1 detects that the predetermined water level has been reached, and if the predetermined water level is reached, energizes the washing pump 7 and the heater 10. In addition, the water supply system of the tap water is carried out by using a divergent faucet 16 or the like from the faucet. The washing water is washed out from the washing nozzle 5 by the washing pump 7, and the dirt adhering to the tableware 3 is removed. At this time, the temperature of the control washing water is detected by the thermistor 丨丨. When the predetermined operation is completed, the drain pump 8 is turned on, and then the washing water containing the dirt originally attached to the tableware 3 is discharged. Next, the rinsing step of re-supplying the tap water is started. The rinsing step in which the heater 10 is not energized and washed several times with water is repeated, and the heating rinsing step in which the heater 1 is turned on and then rinsed with hot water is removed, and the detergent component adhering to the tableware 3 is removed. However, in the above-described structure of the conventional dishwashing machine, in the washing step of removing the stain of the tableware, the foam is generated in the washing water due to the influence of the lotion and the stain attached to the tableware. After the washing step is completed, the washing water is drained, and foam remains in the buoy of the water level detecting portion and the internal drain port. At this time, in the water level detecting portion that detects the water level by using the buoy to move up and down, the movement of the buoy is hindered by the influence of the foam floating on the water. Further, since the washing water containing the foam is discharged, the capacity of the drain water is also affected, and the residual water remaining in the washing layer is not sufficiently drained. Therefore, in the subsequent rinsing step, before the water supply reaches a predetermined amount, the buoy detects the foam floating on the washing water and erroneously detects "to reach the predetermined water level", so that the water supply amount becomes relatively clean, etc. The amount of water is small. 201143698 'Therefore, since it is difficult to accurately detect the amount of water, in order to ensure the amount of water to be washed or washed, the time for replenishment of the feed water is set after the water level detection by the buoy is used. And, taking into account the amount of residual water and the difference between the bubble and the water, take longer to replenish the water. For this reason, there will be a problem of excessive water consumption. [PRIOR ART DOCUMENT] [Patent Document] [Special and Documentary Document 1] Japanese Patent Laid-Open Publication No. U7957 [Brief Description of the Invention] Summary of the Invention The washing machine of the present invention is provided with a washing machine for taking out and placing it by being sprayed. Net I::: First clean tank: The water supply unit that has been supplied to the washing tank has been supplied with water to: the water supply unit in the clean tank: the water supply from the water supply department to the water:: the water level detection unit of the water level And, the control department of the test room. When the control unit detects the water supply until the water level, the supply is continued. _ Continued supply = When the water supply after the test is changed, the difference between the flushing step and the flushing step is reduced. 4 „ Complement, 0 water, and the make-up water according to the washing step The effect of the time: the foam is caused by the lotion and the cadmium residue attached to the tableware, and the buoy is detected in the buoy of the water level detecting part and the internal draining position of the bubble (2): The effect of foam on the water can be determined according to the difference. It is determined whether the water supply time after the 201143698 water level is checked according to the presence or absence of the material, thereby saving water and saving the energy of the heated water. 1 is a longitudinal sectional view of a dishwasher according to an embodiment of the present invention.

I: Embodiment 3 Embodiments for carrying out the invention Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited by the above embodiments. Fig. 1 is a longitudinal sectional view of a dishwasher according to an embodiment of the present invention, and Fig. 2 is a block circuit diagram of a dishwasher according to an embodiment of the present invention. Fig. 3 is a flow chart showing the operation of the dishwasher according to the embodiment of the present invention. Hereinafter, an embodiment of the present invention will be described with reference to Figs. 1 to 3. The cutlery basket 2 is movably arranged for washing. In the clean tank 1, the tableware 3 is housed in the cutlery basket 2. The washing water is supplied by the water supply valve 4 as the water supply unit, and is stored in the washing tank 1. The washing is performed as a washing unit. The nozzle 5 is rotatably supported by the bottom surface in the washing tank 1, and sprays the washing water to the dish 3 while rotating. The discharged washing water enters the drain port of the bottom surface of the washing tank 1. 6. The washing pump 7 pressurizes the washing water and sends it to the washing nozzle 5, and then the washing water is sprayed from the washing nozzle 5. The washing pump 7 is discharged and drained from the 201143698 washing water. The water level detecting unit 9 is disposed in the outer wall of the cleaning tank. The water level detecting unit 9 detects the inside of the washing tank 1. Whether the bit reaches the predefined level or not, the water level is detected by the downward movement of the buoy 9a. Then, the water level detecting unit 9 can also be composed of a pair of electrodes, and the water level can be detected when the electrode is energized. The heater 10 is disposed at the bottom of the washing tank 1 and is heated to wash the water. The outer wall of the bottom of the washing tank 1 is provided with a thermistor 丨丨, and the washing water is detected through the wall surface. The temperature of the air is also provided. The control unit 12 and the power supply circuit 15 are also disposed in the main body. The control unit 12 controls the washing pump 7, the drain pump 8, the heater 10, and the like, and receives the water level detecting unit 9 and the thermistor. The power source circuit 15 generates a power source for the operation unit 13, the display unit 14 for displaying the operation state, and the control unit 12. The cleaning device 15 is used for cleaning the laundry such as the tableware 3 or the chopsticks. The flushed liquid is always called washing water. The water level detecting unit 9 according to the embodiment of the present invention is connected to the washing tank 1 by a water passage outside the communication pipe, and is provided on the side wall outer wall of the washing tank. The water level detecting unit 9 is configured to activate/turn off (ON-OFF) the micro switch 9c by moving downward from the buoy 9a. Further, the control program for performing the water level detection is configured as follows. Water is supplied to the inside of the washing tank 1 by the operation of the water supply valve 4 as the water supply unit. The control unit 12 that controls the washing pump 7, the drain pump 8, and the heater 1 that is the heating unit receives a signal from the water level detecting unit 9 and measures the water supply from the water supply valve 4 until the water level detecting unit 9 detects the water level. Water supply time. Further, the control unit 12 controls to continue the supply of water only for a predetermined time after the water level detecting unit 9 detects the water level. Further, the control unit 12 proceeds to 201143698 to perform control in such a manner that when the difference between the water supply time of the washing step and the flushing step is within the first determination time and the second determination time, only the first predetermined time is shorter. 2 Make up the water for a predetermined time. Further, the control is performed in such a manner that the difference between the water supply time of the washing step and the washing step, that is, the value obtained by subtracting the water supply time of the washing step from the water supply time of the washing step, is greater than or equal to the first determination time or When the second determination time is less than or equal to the second determination time, the makeup water is supplied only for the first predetermined time. In the present embodiment, the predetermined time of the makeup water is assumed to be the time when the influence of the foam is generated, and the difference in the water supply time is a value obtained by subtracting the water supply time of the washing step from the water supply time of the washing step, and 1 The determination time is a positive value, and the second determination time is a negative value. Explain the above actions. When the dishwasher starts to operate, the control unit 12 controls to open the water supply valve 4, and supplies tap water to the bottom of the washing tank 1 as washing water. Since the water level detecting unit 9 and the washing tank 1 are connected by the communication pipe 9b, the tap water is also supplied to the water level detecting unit 9 at the same time. When the water supply step is performed, the water level in the water level detecting portion 9 rises, the buoy 9a floats, and the switch of the micro switch 9c is turned on/off to detect a predetermined water level. Here, the makeup water is only supplied at the first predetermined time. After the water supply is completed, the water supply valve 4 is closed and the washing step starts. In the washing step, the washing water in which the lotion is dissolved is pressurized by the washing pump 7 to be circulated. At this time, there is also a case of foaming due to the influence of the stain attached to the tableware 3. When the washing water containing foam is drained after the washing step is finished, the beads gather at the drain port 6, and the speed at which the washing water flows is lowered. Further, the washing water containing the blistering also lowers the discharge capacity of the drain raft 8. This is because in the drain pump 8, although the 201143698 washing water is pressurized in the portion where there is no foam and the liquid flow rate in the case of draining is fast, the flow rate of the foam is slow in the case where the foam portion is pressurized and drained. . In the case where the control of the drain pump 8 is programmed to operate in a predetermined time, even if the drain pump 8 affected by the foam is operated for a predetermined period of time, the amount of the washing water remaining in the washing tank 1 remains. There will be deviations. Further, since the washing water containing the foam enters the water level detecting portion 9 through the communicating pipe 9b, the foam remains in the water level detecting portion 9 after the washing water is drained. Therefore, in the rinsing step of the next step, since a large amount of washing water remains in the washing tank 1, even if the water is supplied to the predetermined water level at which the water level detecting unit 9 operates, the absolute amount of the water supply for re-supplying will still change. less. Further, due to the influence of the residual foam in the water level detecting portion 9, the buoy 9a erroneously detects the foam floating on the washing water, and erroneously detects that the washing water has reached the predetermined water level before the washing water reaches the predetermined water level. . Due to these effects, the water supply time until the water level detection in the case of foaming will be earlier than in the case of no foaming, so it is possible to determine whether or not there is a bubble generation by measuring the water supply time. That is, when the difference in the water supply time between the washing step and the rinsing step is positive, there is a result of foam generation. In the absence of foam, the water supply time does not change because the water supply time is the same as the reference value. Therefore, if the water supply time after the water level detection is set to the second predetermined time in the case where the foam is affected, and the second predetermined time shorter than the first predetermined time in the case where the foam is not affected, It can be finished without supplying too much water. That is, water saving can be achieved, and since it is not necessary to heat the excess washing water by the heater 10, energy saving can be achieved. However, if the case where the water supply time difference is positive is judged to be foamed 201143698, in actual use, even if there is no foam, it is possible to misjudge the occurrence of foam. The reason for this is that when the water supply to the dishwasher is used to supply water to another tap water machine in the vicinity of the dishwasher, the tap water pressure changes. In addition, the buoyancy is changed by the buoy 9a accumulated in the water level detecting unit 9, and the water supply time varies depending on various differences such as the difference in the operation of the water supply valve 4. For this reason, the cause of the difference can be corrected by the following determination, and the determination of the difference in the water supply time can be accurately performed, that is, the time during which the influence of the bubble is not generated is maintained at the second determination time or longer and the first determination time or lower. The amplitude is determined by setting the time when the influence of the bubble is generated to the first determination time or more. By setting the value determined based on the water supply time difference to not only zero, but also in the first determination time and the second determination time, it is possible to effectively judge the generation of a small amount of foam. The reason is that if there is a generation of foam, even if the predetermined amount of water supply cannot be ensured, as long as the amount of water supply does not affect the operation of the washing pump 7, it is not necessary to reduce the time of the makeup water, and it is also possible to determination. Therefore, when the difference in the water supply time is equal to or greater than the positive value of the first determination time, the influence of the bubble can be accurately determined. Further, when the water supply time difference is less than the negative value of the second determination time, it is generally considered that the water supply time difference cannot be correctly determined for some reason. For example, there is a reason that the water supply time itself or the like cannot be accurately measured because of a reason such as a temporary stop during the water supply step of the flushing step. On the other hand, in the case where the bubble is generated in the washing step, although the water supply time is shortened in the subsequent rinsing step, if the cessation is temporarily stopped during the operation, the water supply time becomes longer. As a result, the difference in the water supply time is a negative value and the absolute value is large.缘10 201143698 For this reason, in the same way, in the same way, if the water supply time is not affected by the foaming time, the water supply time is set to the second time, and the material performance due to false detection can be prevented. . On the other hand, in the case where the water supply step is temporarily stopped, the water supply time difference is determined, and since it is determined that there is foam, there is no problem. Next, the dishwashing_operation according to the embodiment of the present invention will be described in accordance with the operation flowchart shown in Fig. 3. First, (4) After the operation, the water supply time for the water supply to the predetermined water is turned on (step si). Thereafter, the predetermined time_recharge water (step work) is performed. Then, the washing operation is performed and cleaned (step S3). Then, it is determined whether or not the washing step has been completed (step S4). If the washing step is still in the bundle (in the case of stepping on), the process returns to step S3. When the washing step is finished (the step is "γ" In the case of the fruit, the fruit is discharged to discharge the washing water (step enough. Then, the water supply of the rinsing step is started, and the water supply time until the water reaches the predetermined water level (step S6). Thereafter, the entry is made. Foam determination procedure Next, the washing operation is performed and the rinsing is performed (Step 2), and then the first cleaning step is completed (Step (1)). If the kth rinsing step has not been completed (step When Sl3 is "N", the process returns to 4S12. When the first flushing step is completed (step (1) is "丫"), the drain pump wire is fed (township SM). Water supply until the scheduled date ((4) guilty), and the line of the Japanese water supply (Step Lion 6). Also enter here The water supply time meter is just the same, and the same material determination procedure as that of the second rinsing step is performed. Thereafter, the washing (four) is performed and rinsing is performed (step S17) 'Next, the second step is determined whether or not the step is finished (step 201143698 Step S18). If the second flushing step has not been completed (step gig is "N"), the process returns to step S17. When the second flushing step is completed (step S18 is "Y") 'The drain pump is operated to drain (step S19). 0 Finally, the heating and rinsing steps are performed in steps S20 to S24 to end the operation. Since the heating and rinsing steps are the same as the second rinsing step, the description will not be repeated. As described above, the present invention includes a washing tank having an opening for taking out and placing the object to be washed, and a washing unit for spraying the washing water to the object stored in the washing tank. The water supply unit that supplies water to the washing tank, the water level detecting unit that detects the water level of the washing water that has been supplied to the washing tank, and the (four) part that measures the water supply time, and the county water time starts from the water supply unit. Inspection department Time after the control unit detects the water level by the water level detecting unit, and only supplies the water for the water supply for a predetermined period of time, and changes the time of the water supply to the rinse time according to the washing (4) and the water supply time of the rinsing step. The dishwasher is used for the bubbling of the tableware, the bubbling of the Xe, the foaming of the water level detecting part, or the foaming of the internal draining port, which hinders the movement of the buoy due to the influence of the foam. Due to the difference in the water supply time until the test, it can be judged whether there is =; according to the presence or absence of the influence of the bubble, the water supply after the water level detection can be adjusted to save water and save the energy for heating the excess water. In the washing machine, the control unit determines that there is no influence of the bubble when the difference between the washing step and the rushing time is within the first determination time and the second determination time. According to this, even if the supply water time is not regular due to the influence of the change in the water supply pressure of the tap water or the deterioration of the water level detecting unit over the years, the difference can be corrected and the water supply time difference can be accurately determined by the determination within the predetermined time. Ground judgment. Further, the present invention is a dishwasher that determines that the influence of the bubble generation is caused when the difference between the water supply time of the washing step and the rinsing step is equal to or longer than the first determination time or the second determination time. In this way, even if the difference in the water supply time is not properly measured due to some reasons, the water supply necessary for washing and washing can be replenished. For example, in the course of water supply in the rinsing step, irregularities such as the water supply time itself cannot be accurately measured due to temporary suspension or the like. Even in this case, if it is considered that the water supply time cannot be determined and the same makeup water time as in the case of foaming is performed, the water supply necessary for washing and rinsing can be performed by error detection, and the washing can be prevented. The net performance is low. In addition, in the embodiment of the present invention, the initial value of the time for replenishing water is affected by the presence of bubbles, and the time of the replenishment water is set to be shorter than the initial value in the case of no bubble generation, but Conversely, the initial value of the time of the makeup water can be set to the case of the influence of no bubble generation. Further, in the embodiment of the present invention, in the plurality of rinsing steps after the second time, and further in the last heating rinsing step performed thereafter, the water supply time difference is determined to adjust the time of the replenishment water. However, if necessary, the foam determination procedure may be omitted in the second and subsequent rinsing steps.
