而自供水閥13朝洗淨槽1内供入水。一旦對洗淨槽丨内供入 水’則水位檢知槽6内之水位上昇，浮動部7亦上昇，一旦達 2〇到預定之水位’即啓動開關8(S44之Y)。一旦開關8呈啓動狀 態’則藉控制部14關閉供水閥i3(S45)，而停止水之供入。 而後’啓動泵15及加熱器3(S46)，而藉泵15將洗淨槽1 内之洗淨水自排水口 16吸入，再對洗淨喷嘴加以壓送，而 自洗淨噴嘴強勢加以喷射。藉該強勢喷射之洗淨水，即可 200913952 洗淨食器籃5中收納之食器4。 自洗淨噴嘴強勢喷射之洗淨水將重自排水口 16吸入， 而再度自洗淨噴嘴強勢噴出。重複以上循環作業，同時辑 加熱器3製造溫水，即可提昇洗淨效果。 5 而後，在開關8未啓動之狀態下（S47之Y)，藉泵15之時 間管理及洗淨水之溫度管理等，而於判斷預定時間之洗淨 已結束時，關閉泵15及加熱器3(S49)而停止洗淨作業，再開 啓泵15以進行排水(S5〇)。排水完畢後，關閉泵15(851)，而 結束洗淨程序。 10 繼之’重複進行程序S43至程序S51之程序3次，再進行 沖洗程序(S52)。 繼而’啓動乾燥風扇（未圖示）(S53)，並啓動加熱器 3(S54) ’而乾燥食器後’再關閉加熱器3(S55)，並關閉乾燥 風扇（S56)，而結束乾燥程序。然後，關閉電源開關（S57)， 15 而結束所有程序。 另’尤其’洗淨程序中係使含有多量洗劑成分之洗淨 水循環’故易產生泡沫。因此，為避免因洗淨水之循環而 產生泡沫’通常係使用界面活性劑之含量較低之專用洗 劑’但若誤用界面活性劑含量較高之洗劑而進行運轉，則 20洗淨水之循環將導致泡沫大量產生。泡沫不久則移動至與 洗淨槽1相連通之水位檢知槽6，並於程序S48内，開關8之 啓動狀態持續5秒時(S48之Y)，判斷為泡沫之異常產生，而 實施規定次數之進行排水動作及供水動作之減泡程序。 即’關閉用以洗淨之泵15及加熱器3(S58)，再開啓泵 7 200913952 15以進行排水（S59)，而於排水後關閉用以排水之泵 15(S60)，再打開供水閥13(S61)而進行供水。若對洗淨槽i 供入預定之水，則開關8將啓動（S62之γ)，而供水閥13則關 閉（S63) ’而停止供水。藉此即可進行減泡。程序至程 5序S63之減泡程序將重複2次(S64)。 另，私序S44及程序S62中，若開關8經20分鐘仍未啓動 (S64之N及S62之N)，則判斷為發生異常而進行異常報告 (S65及S66)。 如上所述，檢知泡沫之異常產生，即可防止泡沫自水 10位檢知槽6溢出，而使設於外箱11底部之漏水檢知部12作 動，形成漏水狀態。 然而，上述之習知之洗碗機不問泡沫之產生程度而僅實 施規定次數之減泡程序，故當洗淨水中之界面活性劑之濃度 較高時，規定之減泡程序亦無法充分稀釋界面活性劑，而將 15再產生泡沫而使漏水檢知部12作動而造成運轉停止。 又，即使洗淨水中之界面活性劑之濃度不高，但程序 S48中開關8已啓動而改行減泡程序時，亦不問減泡程序之 進行必要與否，仍然實施規定次數之減泡程序結果則造 成洗淨時間之浪費。 20 此外，視洗淨水中之界面活性劑之濃度不同，泡沫可 能急劇產生，而在程序S48中使開關8啓動維持5秒狀離之 前，泡沫即流入與洗淨槽1相連通之送風通道（未圖示），並 進而產生泡沫，而導致送風裝置（未圖示）亦受影響，^成送 風性能降低、絕緣電阻亦降低之問題。 、 8 200913952 且，由於不問泡沫之產生程度而僅實施規定次數之減 泡程序，故洗淨水中之界面活性劑之濃度較高時，減泡程 序亦無法稀釋界面活性劑，而將再度產生泡沫，流入同樣 與洗淨槽1相連通之送風通道，進而產生泡沫，流入送風裝 5 置，而造成送風性能降低、絕緣電阻亦降低之問題。 【發明内容3 發明概要 本發明係為解決上述習知之問題而設計者，其目的在 提供一種洗淨裝置，即使使用者誤用界面活性劑含量較高 10

INSTRUCTIONS: [Invention] *=2^Technology 4^" Field 3 Field of the Invention The present invention relates to a type of dishwasher that can wash and dry food containers, etc., which can be foamed and washed. Wash the device. Background of the Invention In the past, the dishwasher disclosed in Japanese Laid-Open Patent Publication No. 2003-220009 has the configuration shown in Fig. 3. Fig. 3 is a side view of a conventional dishwasher disclosed in Patent Document 1. The following description will be made on the structure. In Fig. 3, the dishwasher main body 3 of the conventional dishwasher is provided with an opening portion 30a, and the washing tub 1 is mounted so as to be accessible through the opening portion 3a. 15 At the center of the bottom of the washing tank 1, a washing nozzle 2 is disposed to be rotatable freely, and a heater 3 is disposed, and an apparatus blue 5 for accommodating the food container 4 is provided above. X, wash the tank! It can be connected to the water level detecting tank 6 provided in the vicinity thereof via the pipe 17. The water level detecting groove 6 is provided with a floating portion 7 movable in the vertical direction, and above the floating portion 7, a water level switch 8 (hereinafter referred to as a "switch" that can move up and down with the floating portion 7 is provided. %) The floating portion 7 and the switch 8 constitute a water level detecting portion that can detect the water level. The auxiliary pipe _ connected to the self-draining pipe 9 is connected to the auxiliary pipe _ the inside of the tank is cleaned by the water level detecting tank 6. The water leak detection unit 12 is externally detected, and the water level detection is detected. 20 200913952 The water supply valve 13 as the water supply unit is provided on the upper side of the washing tank 1 and the bottom of the tank 1 is provided to discharge the supplied water. Wash the water in the tank, K port 16. Pump pump 15 (hereinafter referred to as "pump 丨 5") can be used to drain the water from the drain 〇ΐ6, and then clean the washing nozzle. Pressing, while self-cleaning spray = potential jet washing water. The washing water that is strongly sprayed by the washing nozzle is rushed to the food container 4 stored in the food basket 5, and then the washing water is taken in from the drain port 16 to repeat the above-mentioned circulation operation, and the warm water is produced by the heater 3, Λ Improve the washing effect. The control unit 14 is configured by the switch of the switch 8 and the switch of the water supply valve 丨3. The '10 pump 15 can be used for washing as described above, and the drain side can be switched to the drain when the cleaned water is discharged to the outside of the machine after the respective procedures of the washing process and the flushing procedure described later are completed. Piping 9 is used as a drainage nest ± summer or drained. 15 Figure 4 is a flow chart of the operation of the dishwasher. The following is a description of the action of the dishwasher. That is, using the figure, it is said that each of the operation programs touches the electric power switch (not shown) of the dishwasher (S41) and the start key (not shown) (S42) at the initial stage, and the water supply valve is opened, and the water supply is self-supply. The valve 13 supplies water into the washing tank 1. When the water is supplied to the washing tank, the water level in the water level detecting tank 6 rises, and the floating portion 7 also rises. When the water level reaches the predetermined water level, the switch 8 is activated (Y of S44). When the switch 8 is in the activated state, the water supply valve i3 is closed by the control unit 14 (S45), and the supply of water is stopped. Then, the pump 15 and the heater 3 are started (S46), and the washing water in the washing tank 1 is sucked from the drain port 16 by the pump 15, and the washing nozzle is pumped, and the self-cleaning nozzle is strongly injected. . With this powerful jet of washing water, the food container 4 stored in the food basket 5 can be washed in 200913952. The washing water that is strongly sprayed from the washing nozzle will be sucked in from the drain port 16 and will be ejected from the washing nozzle again. Repeat the above cycle operation, and at the same time, the heater 3 can produce warm water to improve the cleaning effect. 5 Then, in a state where the switch 8 is not activated (Y of S47), the time management of the pump 15 and the temperature management of the washing water are performed, and when the washing of the predetermined time is judged to be finished, the pump 15 and the heater are turned off. 3 (S49), the washing operation is stopped, and the pump 15 is turned on to perform drainage (S5〇). After the drain is completed, the pump 15 (851) is turned off, and the washing process is ended. 10 Next, the program of the program S43 to the program S51 is repeated three times, and the flushing process is performed (S52). Then, the drying fan (not shown) is started (S53), and the heater 3 (S54)' is turned on to dry the food container, and then the heater 3 is turned off (S55), and the drying fan is turned off (S56), and the drying process is ended. Then, turn off the power switch (S57), 15 and end all programs. In addition, in particular, in the washing process, the washing water containing a large amount of the lotion component is circulated, so that foaming is likely to occur. Therefore, in order to avoid the foam generated by the circulation of the washing water, it is usually a special lotion having a lower content of the surfactant. However, if the lotion with a high surfactant content is misused, 20 washing water is used. The cycle will result in a large amount of foam. The foam moves to the water level detecting tank 6 that communicates with the washing tank 1 in the short-term, and in the program S48, when the starting state of the switch 8 continues for 5 seconds (Y in S48), it is determined that the abnormality of the foam is generated, and the regulation is implemented. The number of times is reduced by the drainage operation and the water supply operation. That is, 'the pump 15 and the heater 3 for washing are turned off (S58), and then the pump 7 200913952 15 is turned on to drain (S59), and after draining, the pump 15 for draining is closed (S60), and then the water supply valve is opened. Water supply is carried out at 13 (S61). When the predetermined water is supplied to the washing tank i, the switch 8 is activated (γ of S62), and the water supply valve 13 is closed (S63)' to stop the water supply. This allows for defoaming. The bubble reduction procedure of the program to program S63 will be repeated twice (S64). Further, in the private sequence S44 and the program S62, if the switch 8 has not been activated for 20 minutes (N of S64 and N of S62), it is determined that an abnormality has occurred and an abnormality report is made (S65 and S66). As described above, when the abnormality of the foam is detected, the foam can be prevented from overflowing from the water level detecting tank 6, and the water leakage detecting portion 12 provided at the bottom of the outer casing 11 can be operated to form a water leakage state. However, the above-mentioned conventional dishwasher only performs the predetermined number of defoaming procedures regardless of the degree of foam generation. Therefore, when the concentration of the surfactant in the washing water is high, the prescribed defoaming procedure cannot sufficiently dilute the interfacial activity. The agent re-generates the foam to cause the water leakage detecting unit 12 to act to stop the operation. Further, even if the concentration of the surfactant in the washing water is not high, when the switch 8 is started in the program S48 and the defoaming process is changed, the result of the defoaming process is still performed regardless of whether or not the defoaming process is performed. It causes a waste of washing time. Further, depending on the concentration of the surfactant in the washing water, the foam may be generated abruptly, and before the switch 8 is activated for 5 seconds in the procedure S48, the foam flows into the air supply passage communicating with the washing tank 1 ( Not shown in the figure, and further foam is generated, and the air blowing device (not shown) is also affected, which causes a problem that the air blowing performance is lowered and the insulation resistance is also lowered. , 8 200913952 Moreover, since only a specified number of foam reduction procedures are carried out regardless of the degree of foam generation, when the concentration of the surfactant in the washing water is high, the foaming procedure cannot dilute the surfactant, and foam will be generated again. It flows into the air supply passage which is also connected to the washing tank 1, and generates foam and flows into the air supply device 5, which causes a problem that the air blowing performance is lowered and the insulation resistance is also lowered. SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to provide a cleaning apparatus which can be sufficiently diluted even if a user operates by using a lotion having a higher surfactant content of 10 The surfactant acts to prevent the problem that the device body stops acting and cannot be used. Further, it is an object of the present invention to provide a cleaning apparatus which can operate at an appropriate washing time without a time-consuming defoaming procedure when the concentration of the surfactant in the washing water is low. 15 Further, the present invention can also provide a cleaning device, and when the concentration of the surfactant in the washing water causes the foam to be sharply generated, the foam reduction process is appropriately performed to suppress the generation of the foam, and the foam is prevented from flowing into the air blowing device to avoid the air blowing performance. And the reduction of insulation resistance, and improve reliability. In order to solve the above problems, the cleaning device of the present invention comprises: 20 a cleaning tank disposed in the apparatus body having an opening in the front; a cleaning nozzle disposed in the cleaning tank; and a pump unit The washing nozzle presses the washing water; the water supply unit supplies water to the washing tank; the drain portion discharges the water in the washing tank; and the water level detecting unit detects the inside of the washing tank. The water level; the bubble detecting portion can detect that the difference in the foam in the washing tank is often generated in 200913952; and the control unit can control the operation of each of the above parts; and the control unit measures the foregoing in the foam detecting unit After the abnormality of the bead is generated, the defoaming process from the drainage in the washing tank and the water supply to the washing tank is performed in accordance with the amount of the foam generated. 5 With the above configuration, the cleaning device of the present invention can respond to the amount of foam generated, and by performing the foam reduction procedure, when the user misuses the lotion having a higher surfactant content, it is more conventionally known. The foam reduction process. Therefore, there is no problem that the bubble is overflowed from the water level detecting groove of the water level detecting unit, and the water leakage detecting unit is actuated, causing the device body to stop operating to form a 10 unusable state. Moreover, since the foam can be prevented from flowing into the air supply passage or the like, the decrease in the air supply amount due to the inflow of the foam can be avoided, that is, the drying performance can be prevented from being lowered, and the foam can be prevented from adhering to the charging portion of the air blowing portion to cause electricity. Reduced insulation properties. 15 Moreover, if the foam concentration is detected when the surfactant concentration in the washing water is low, since the amount of foam generation is also small, the number of times of the foam reduction procedure can be reduced, and the foam reduction procedure is appropriately performed to save unnecessary The operating time allows efficient operation of the device body. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side cross-sectional view of a dishwasher according to an embodiment of the present invention. Figure 2 is a flow chart showing the operation of the dishwasher. Figure 3 is a side cross-sectional view of a conventional dishwasher. Figure 4 is a flow chart showing the operation of a conventional dishwasher. 10 200913952 [Poor mode] The detailed description of the preferred embodiment of the mouth net m containing ^ wash tank, set in front of the open 2 _; washing materials, placed in the front view of the clear trough; Washing ^The above washing 10 15 ::::, water; draining part, discharging the above _= can be ^vp, can detect the water level in the above washing tank; foam detection department, =: bubble in the clean tank An abnormality occurs; and the control unit controls the slave operation, and the control unit cuts out the abnormality of the month=bubble after the bubble is detected, and then performs the cleaning tank according to the amount of the foam generated. (4) The defoaming procedure of the water supply in the aforementioned washing tank. With the above configuration, the cleaning device of the present invention can respond to the amount of generation of the beads, and by performing the defoaming process, it is more conventional when the user misuses the lotion having a higher surfactant content. Under-reduction process. Therefore, it is not caused that the water level detection tank of the water level detecting unit overflows, and the water leakage detecting unit is actuated, causing the apparatus main body to stop operating and forming an unusable state. Moreover, since the foam can be prevented from flowing into the air supply passage or the like, the decrease in the air supply amount due to the inflow of the bubble can be avoided, that is, the drying performance can be prevented from being lowered, and the foam can be prevented from adhering to the charging portion of the air supply portion. This leads to a reduction in electrical insulation properties. Moreover, if the concentration of the surfactant in the washing water is low, the foam is detected, and since the amount of foam generation is also small, the number of times of the defoaming procedure is reduced, and the defoaming procedure is appropriately performed to save the excess. The operating time, 200913952, allows the unit to operate efficiently. Further, according to the cleaning apparatus of the present invention, the foam detecting unit can estimate the amount of generation of the foam in accordance with the time and the number of times the abnormality of the foam is detected. 5 By the above structure, for example, if the time and number of occurrences of the abnormality of the bubble are small, it is estimated that the amount of foam generation is large, and if the time and number of occurrences of the abnormality of the bubble are large, it is estimated that the bubble is generated. Since the amount is small, the amount of foam generated in the pre-cleaning tank can be simply constructed, so that various controls relating to the amount of foam generation can be easily performed. Further, according to the washing apparatus of the present invention, the foam detecting unit may detect the abnormality of the foam in the washing tank by the output of the water level detecting unit. According to the above configuration, the structure can be simplified, and the water level in the washing tank and the abnormality of the foam can be detected, so that a highly reliable washing device can be provided. Further, according to the cleaning apparatus of the present invention, the control unit can increase or decrease the number of times of the bubble reduction process performed when the abnormality of the foam occurs, depending on the amount of the bubble generation. According to the above configuration, if it is estimated that the amount of the beads is large, the number of times of the defoaming process from the washing tank and the water supply to the washing tank can be increased. Moreover, if it is estimated that the amount of foam generated is small, the number of times of the defoaming process from the washing tank and the water supply to the 20 washing tank can be reduced. As described above, the present invention can easily perform the defoaming process in accordance with the degree of abnormality of the foam in the washing tank.

設於在前方具有開口部l〇〇a之洗碗機本體1〇〇内之洗淨槽 101、配置於該洗淨槽101内之洗淨噴嘴102、可對該洗淨喷 嘴102壓送洗淨水之泵116、可對洗淨槽1〇1内供水之供水閥 115、可排出洗淨槽101内之水之排水口 1〇6及泵116所構成 之排水裝置、水位檢知槽108内之浮動部1〇9上下移動而使 10排水配管111啓動以檢知洗淨槽101内之水位之水位檢知 部、可檢知洗淨槽101内之泡沫之異常產生而由浮動部109 及開關110所構成之泡沫檢知部、用以控制其等各部動作之 控制部117，而，控制部117則構成可使泡沫檢知部對應諸 如裎序S207中泵116之關閉至開關110啓動所需之時間，而 15於測得泡沫之異常產生時，藉測得泡沫之異常產生之時 間、次數而推測泡泳產生量，再對應其產生量而實施可自 洗淨槽101排水及對洗淨槽101供水之減泡程序。 藉上述構造，本實施例之洗碗機可對應泡沐產生量而 進行減泡程序，故即使使用者誤用界面活性劑含量較古之 20洗劑而進行運轉，亦不致發生泡珠自具有水位檢知:水 位檢知槽應等處溢出’而使漏水檢知部114作動，造成洗 碗機本體⑽之運轉停止，㈣成何❹狀態之問題/ 又’由於可避免泡泳流入送風通道m等處，故可避免 泡沫流入所造成送風量之降低，即， J避免乾燥性能之降 20 200913952 低。進而，亦可避免泡沫附著於送風部之充電部等處而導 致電性絕緣性能之降低。 又，若於洗淨水中之界面活性劑濃度較低時進行泡沫 檢知，由於泡沫產生量亦較少，故可減少減泡程序之實施 5 次數等，而適當進行減泡程序，以節省多餘之運轉時間， 故可有效率地運轉裝置本體。 又，依據本實施例，泡沫之產生量可由浮動部109及開 關110所構成之泡沫檢知部對應測得泡沫之異常產生之時 間及次數而加以推測。 10 藉上述構造，舉例言之，若測得泡沫之異常產生之時 間及次數較少，則可推測泡沫產生量較多，若測得泡沫之 異常產生之時間及次數較多，則推測泡沫產生量較少。故 而，可以簡單構造推測洗淨槽101内之泡沫產生量，故可輕 易進行與泡沫產生量有關之各種控制。 15 又，本實施例之前述泡沫檢知部可藉使水位檢知槽108 内之浮動部109上下移動而使開關110啓動以檢知洗淨槽 101内之水位之水位檢知部之輸出，而於關閉泵116後，檢 知洗淨槽101内之泡沫之異常產生。 故而，可簡化構造，而檢知泡沫之異常產生，故可提 20 供可靠度較高之洗碗機。 又，本實施例中，控制部117係構可依據泡沫檢知部測 得泡沫之異常產生之時間、次數，而增減在已發生泡沫之 異常產生時動作之減泡程序自洗淨槽101内排水及對洗淨 槽101供水之次數者。 21 200913952 因此’若測得泡洙之異常產生之時間、次數較少，則可 推測泡沫產生量較多’而增加減泡程序自洗淨槽101内排< 及對洗淨槽101供水之次數。而，若測得泡沫之異常產生之 時間、次數較多，則可推測泡珠產生量較少，而減少減、包矛。 序自洗淨槽101内排水及對洗淨槽101供水之次數。藉此，即 可對應洗淨槽101内之泡洙產生程度而進行減泡程序。 10 又，本實施例中，控制部117構成可於洗淨程序之、 初期 進行之泡沫之異常產生之複數次檢知，並依測得泡沐之異 常產生之時間、次數不同，而推測泡沐之產生量，且對應 其產生量’而實施可自洗淨槽101内排水及對洗淨槽1〇1供 水之減泡程序 藉上述構造，即使使用者誤用界面活性劑含量較g之、先 劑而進行運轉，亦可於容易產生泡沫之時期進行泡沫檢知， 而可避免泡沫自水位檢知槽108等處溢出，致使漏水檢知部 15 114作動而使洗碗機形成不可使用狀態，以提昇可靠度。 又，本實施例中，另設有可自排氣口 121排出洗淨槽ι〇ι 内之蒸氣之送風農置120，以及連通該送風裝置12〇與洗淨 槽1()1之送風通道118,控制部117則構成可於洗淨程序之初 期至少進行1次泡沫之異常產生之檢知，並於測得泡泳之異 20常產生時，在泡沫檢知當時，即令送風裝置120動作預定之 時間，並實施可自洗淨槽101内排水及對洗淨槽1〇1供水之 減泡程序。 藉上述構造’即可使流入送風通道m之泡沐流回洗淨 槽1〇1内’而避免泡沫流入所造成送風量之降低，即，可避 22 200913952 免乾燥性能之降低，且，亦可避免泡沫附著於送風筆置i2〇 之充電部等處而導致電性絕緣性能之降低。 又，本實施例中，泡沫檢知部係構成可依測得泡末之 異常產生之時間、次數，而增減泡沫已異常產生時動作之 5适風裝置120之運轉時間。 藉上述構造，若測得泡沫之異常產生之時間、次數較 少’則推測泡沫之產生量較大，而可增加送風袭置12〇之送 風時間。而，若測得泡沫之異常產生之時間、次數較多， 則推測泡沫之產生量較小，而可減少送風裝置12〇之運轉時 1〇 間。故而，可使流入送風通道118之泡沫對應已產生之泡沫 量確實地流回洗淨槽101，而避免泡沫流入所造成送風量之 降低’即，可確實避免乾燥性能之降低。進而，亦可確實 避免泡沫附著於送風裝置120之充電部等處而導致電性絕 緣性能之降低。 另，本實施例中，雖比較在泵116之關閉至開關11〇啓 動所需之時間與預定時間而決定減泡程序之重複次數C,但 本發明並不限於此，若對應開關110啓動之前之時間長而改 變重複次數C，則泡沫檢知次數可為丨次。 如上所述，本發明之洗淨裝置可以簡單之構造檢知泡 /束之大量產生，甚且，亦可有效率地減少已產生之泡沫。 又，並可避免漏水檢知部之作動造成運轉停止，同時確保 與洗淨槽相連^之送風部等零件之電性絕緣性能等，而兼 具安全性及可*度。且，不限於洗碗機，而亦{適用於可 產生泡沫之洗衣機等各種機器。 23 200913952 L圖式簡單說明3 第1圖係本發明一實施例之洗碗機之側截面圖。 第2圖係顯示該洗碗機之動作之流程圖。 第3圖係習知之洗碗機之側截面圖。 5 第4圖係顯示習知洗碗機之動作之流程圖。

"switch" that can be operated in conjunction with the movement of the floating portion (10) in the vertical direction is disposed just above the floating portion. U 15 20 The moving part just opens with the water level _〇 constitutes the water level detecting unit that can detect the water level: The water level detecting tank (10) is connected to the lu branch 112 when it is self-draining, and the gentleman _Ί^人^ 士Α X疋Auxiliary officer, outside _= clean water level detection tank (10) inside. Bottom. 卩 There is a leak detection department, knowing that the tank 108 is leaking. It can be detected that the upper part of the water level cleaning tank 101 is provided as a wash. The bottom of the clean tank 1〇1, the water supply valve 115 of the 邛, the drain port 1. 6 1 _ (hereinafter referred to as "the water of the magical water 106 inhalation washing material, re-water port delivery" and self-cleaning nozzle 1 〇 2 strong cut water t1G2 to press the wrong self-washing nozzle〗 〖02 14 200913952 Strong spray of washing water, you can wash the food container 104 stored in the food basket 105, and then inhaled from the drain 1〇6 Clean water. Repeat the above cycle operation, and use the heater 103 to make warm water to improve the cleaning effect. Switch 11 〇 switch The control of each component such as the switch of the water supply valve 115 is performed by the control unit 5117. The pump 116 can be used for washing as described above, but is also the same as the conventional one, and can be used as a discharge to the outside of the machine. In the case of washing water, the drain side is switched to the drain pipe 111 and used as a drain or a drain pump. The above structure is the same as the conventional structure shown in Fig. 3, but the dishwasher of the present embodiment 10 And a blower device 可2〇 that can be blown from the air supply port 119 to the washing tank 1〇1 via the air supply passage 118 that communicates with the washing tank 〇1. That is, in the drying process after the washing process, The air supply device 12 is supplied with air from the air supply port 119 to the cleaning tank 101, and is warmed up by the heater 1〇3 to warm up the food container 15 stored in the food container basket 1〇5 above the heater 103. 4, the water of the food container 104 is evaporated. Further, the air sent to the cleaning tank 101 by the air blowing device 12 is discharged from the exhaust port 121 disposed above the washing tank 1〇1 together with the steam. And the food container 1〇4 is dried. The operation of the dishwasher of the embodiment constructed as above 2 is a flow chart showing the operation of the dishwasher of the present embodiment. In FIG. 2, the user touches the power switch (not shown) (S2〇i) and touches the start key. (not shown) (S202), the water supply valve 115 (S2〇3) is opened, and the washing tank 101 is supplied with water. Thereby, the water level in the water level detecting tank 108 that communicates with the washing tank 101 rises. Therefore, as the water level of the washing tank 101 rises, the float will rise even if the switch 110 is 109. Next, once the predetermined water level 15 is reached, 200913952 is activated (S204), and the water supply valve 115 is closed by the control unit 117 (S205) 'And stop the water supply. Then, the pump 116 and the heater l〇3 are activated by the control unit 117 (S206), and the washing water in the washing tank ιοί is sucked from the drain port 106 by the pump 116 and is sent to the washing nozzle 1〇2. . By washing the 5 spray nozzles 2 with a strong spray of the washing water, the food can be stored in the food container 105 and the washing water is again sucked from the drain 106. The above cycle operation is repeated, and the washing water is heated by the heater 103 to improve the washing effect. When the pump 116 is operated, the water in the washing tank 101 is sucked, so that the water level in the washing tank 101 and the water level detecting tank 1〇8 is lowered, and the switch 11〇 is in an unactivated state. At this time, if the user misuses the lotion having a high surfactant content, the foam will be generated in a large amount along with the circulation of the washing water, and the foam will soon flow into the washing tank 101, the washing nozzle 102, the pump 116, and the drain. Mouth 106. In this state, if the operation (10) 7 of the pump 110 is stopped, the water level of the washing tank 1〇1 and the water level detecting tank 108 will depend, and the switch 110 will be activated again. The time required from the stop of the milled 116 to the time when the switch U0 is again activated is more time consuming than the time when the bubble bed is filled with the drain 〇1〇6 and the (4)7. Therefore, the bead detection can be performed with respect to the time required for the stop of the self-magic 16 to the switch (4) to be in the activated state again (S208). For example, the time required from the stop of the pump 116 to the switch 11 〇 once again is started if the bead has abnormally generated. 1 Right (four) material time, you can judge the bubble force 甩沬 甩沬 detection can also be known to the red stone ~ t method for it. That is, it is also possible to make the switch 11 〇 continuous enemy after the enemy pump 1163, and determine the measured squeak when the time is advanced. At this time, for example, it can be used to determine the abnormality of the bubble by the predetermined time of 16 200913952. As described above, in the present embodiment, the floating portion 109 and the switch ι10 constitute a water level detecting portion that can detect the water level in the washing tank 101, and also serves as a method for detecting the abnormality of the foam in the washing tank 101. The bubble detecting unit performs switching of the operations of the individual units 5 by the control unit 117. After the abnormality of the bubble is detected in the process S208 (γ of S209), in a state where the pump 116 and the heater 103 are both turned off (S209), the air blowing device 120 (S210)' is turned on and the air blowing device is turned off after the predetermined time a has elapsed. I2〇(s211). Further, the pump 116 is turned on to drain (S212), and after a predetermined time, the 10 gather 116 (S213)' is turned off to end the drain. Then, the water supply valve u5 (s2i4) is opened to supply water to the washing tank 101. The water supply causes the water level in the washing tank 1 to rise, and the switch 110 is activated (Y in S215) to close the water supply valve 115 (8216). Then, the defoaming procedure of the program S212 to the program S216 is repeated a total of c times (S217). After repeating the defoaming process a predetermined number of times as described above, the pump 15116 is opened, and if necessary, the heater l3 is also turned on (S218) to perform cleaning in the washing tank 1〇1. After the predetermined time, the fruit 116 is turned off, and when the heater 丨〇3 is turned on, it is also turned off (S219), and as in the prior art, after the draining process, the rinsing process and the drying process are performed, and the washing of the eater is ended. In addition, the lotion having a high surfactant content has a tendency to easily generate bubbles with the 20-ring of the washing water. Therefore, in the present embodiment, the plurality of times are performed in the initial stage of the washing process (in FIG. 2, N times) The above foam detection can be used to understand the degree of foam generation. That is to say, the amount of foam generated is large when the first bubble is detected, and the amount of foam is large. If the bubble is detected from the second to the Nth, then the amount of foam generated is 17 200913952. The less the number of times, the number of times the amount of foaming in the self-cleaning tank 101 is changed by the white water and the water supplied to the washing tank 101 after the respective foaming is detected is changed. And change, and the corresponding bubble example s, as shown in Figure 2, the observation of the second time, the bubble reduction procedure - the Nth time is measured, the second time in the bubble detection ~ 10 15 20 When the amount of bubble swimming is large, the washing water can leak into the outer box from the water level detecting tank (10); = out of the machine, and avoid the movement of the knowing part (1). Moreover, in the case of 3, the air supply device 120 and the air supply passage 118' which are caused by the water leakage detection are connected to the cleaning tank 101, the number of times of the defoaming procedure can be reduced, and the amount of the bubble generation is small. Quickly reply to the usual cleaning procedure. The bubble detection has been carried out, and the amount of bubble generation 119 of the cleaning tank (8) flows into the air supply U12G through the air supply passage m, and the material is more likely to be sent from the air supply device 120.改变 Change in the number of times the product is detected. The action time is shouted in the long picture 2 'The first air bubble device 120 when the air bubble device is detected is the second action time: r, j is the second bubble input time _ ', and the tenth phase action time X is The shortest. That is, if a>b times, the operation time of the Nth bubble detection is gradually shorter than the 1st 4th rate, and it is confirmed that the time is higher than the delivery position of the air supply passage ιΐ8, and the end of the air supply is called 9 flow back to the cleaning tank (8). Fig. 2 Φ 则田, if the foam is not detected in the program S208 (N of S208), 18 200913952 is the same as the program S206 to the program S20S, first, the pump 116 and the heater 103 are started (S220), and then the cleaning tank is performed. Wash in 1〇1. Thereby, the switch 11A is turned off, and the pump 116 and the heater 103 (3221) are turned off in this state. As described above, 5 times is required for the switch 11 to be activated after the pump 116 is turned off, and the switch 11 is activated. The bubble detection is performed in the same manner as the program S208 (S222). When the bubble abnormality is detected in the routine S222 (γ in S222), the pump 116 and the heater 1〇3 are turned off in the same state as the routine S2〇9 (S223), and the air blowing device 12 is started in the same manner as the program S210 ( S224). Then, the air blowing device 120 is turned off at a predetermined time (S225). Further, the defoaming procedure of the execution program S212 to the program S216 is repeated less than c times and is D times (S226). Then, the pump 116 and the heater 1〇3 (8218) are activated to perform cleaning in the cleaning tank 101, and then the pump 116 and the heater 103 are turned off (S219) to divert the draining program. When the second bubble detection in the step S222 does not detect the abnormality 15 of the bubble (S2222N), the procedure of starting the pump 116 and the heater 1〇3 is reversed as described above (S228). Thereafter, the foam is detected several times, and if the foaming of the Nth time is not detected, the pump 116 and the heater 103 are turned off (S229) in the same manner as in the procedure S2〇7. Then, the abnormality of the Nth bubble is detected in response to the time required for the pump 116 to be turned off until the switch 11 is turned on (S230). If the abnormality of the bubble is detected in the program S230 (Y of S230), the pump 116 and the heater 1〇3 are turned off (S231), and the air reaching device 120 (S232) is turned on, in the same manner as the procedure of S223 to S226, for a predetermined time. The closing of the air blowing device 12 is turned off (S233), and the bubble reducing process of the program S212 to the program S216 is repeated (S234). 19 200913952 Further, as shown in FIG. 2, in the program S204 and the program S215, even after the water supply, if the switch 110 is not activated after the predetermined time elapses (N of S204 and N of S215), it is judged that the apparatus body is abnormal. An exception report is made (S235 and S236). As described above, according to the present embodiment, the cleaning apparatus of the present invention comprises: 5 a cleaning tank 101 provided in the inside of the dishwasher body 1 having the opening portion l〇〇a in the front, and is disposed in the cleaning tank The washing nozzle 102 in the 101, the pump 116 capable of pumping the washing water to the washing nozzle 102, the water supply valve 115 capable of supplying water into the washing tank 1〇1, and the drain water capable of discharging the water in the washing tank 101 The drain unit 1〇6 and the pump unit 116 and the floating unit 1〇9 in the water level detecting tank 108 move up and down, and the 10 drain pipe 111 is activated to detect the water level detecting unit in the washing tank 101. The foam detecting unit composed of the floating portion 109 and the switch 110 and the control unit 117 for controlling the operation of each unit such as the floating portion 109 can be detected, and the control unit 117 can be configured. The bubble detecting portion corresponds to the time required for the pump 116 to be turned off to the start of the switch 110 in the sequence S207, and 15 when the abnormality of the measured bubble is generated, the bubble generation is estimated by the time and the number of times the abnormality of the bubble is detected. Amount, and corresponding to the amount of production, the self-cleaning tank 101 drains and the cleaning tank 101 Save water soak procedure. According to the above configuration, the dishwasher of the embodiment can perform the bubble reduction process according to the amount of foam generation, so even if the user misuses the surfactant content of the 20th agent to operate, the bubble does not have a water level. It is detected that the water level detecting tank should overflow at the same place, and the water leakage detecting unit 114 is activated, causing the operation of the dishwasher body (10) to stop, and (4) the problem of the state of the body / and 'because the bubble can be prevented from flowing into the air supply passage m Waiting, so as to avoid the decrease in the amount of air supplied by the inflow of the foam, that is, J avoids the drop in drying performance 20 200913952. Further, it is also possible to prevent the foam from adhering to the charging portion of the air blowing portion and the like, and the directivity of the conductive property is lowered. Moreover, if the foam is detected when the concentration of the surfactant in the washing water is low, since the amount of foam generation is also small, the number of times of the defoaming procedure can be reduced, and the defoaming procedure is appropriately performed to save unnecessary The operating time allows efficient operation of the device body. Further, according to the present embodiment, the amount of foam generated can be estimated by the bubble detecting portion composed of the floating portion 109 and the switch 110 in accordance with the time and number of times the abnormality of the measured bubble is generated. 10 By the above configuration, for example, if the time and number of occurrences of the abnormality of the bubble are small, it is estimated that the amount of foam generation is large, and if the time and number of occurrences of the abnormality of the bubble are detected, it is estimated that the bubble is generated. Less quantity. Therefore, it is possible to easily construct the estimated amount of foam generation in the cleaning tank 101, so that various controls relating to the amount of foam generation can be easily performed. Further, the foam detecting unit of the present embodiment can activate the switch 110 to detect the output of the water level detecting unit of the water level in the washing tank 101 by moving the floating portion 109 in the water level detecting tank 108 up and down. After the pump 116 is turned off, the abnormality of the foam in the washing tank 101 is detected. Therefore, the structure can be simplified, and the abnormality of the foam can be detected, so that a dishwasher with high reliability can be provided. Moreover, in the present embodiment, the control unit 117 can increase or decrease the defoaming procedure self-cleaning tank 101 that operates when the abnormality of the foam has occurred according to the time and the number of times the abnormality of the foam is detected by the foam detecting unit. The inner drain and the number of times the water is supplied to the washing tank 101. 21 200913952 Therefore, if the time and number of occurrences of the abnormality of the bubble are small, it is estimated that the amount of foam generation is large, and the bubble reduction process is increased from the inside of the washing tank 101 < and the water supply to the washing tank 101 is increased. frequency. However, if the time and number of occurrences of the abnormality of the bubble are measured, it can be inferred that the amount of generation of the bubble is small, and the reduction and the reduction of the spear are considered. The number of times of draining from the washing tank 101 and supplying water to the washing tank 101 is sequentially performed. Thereby, the bubble reduction process can be performed in accordance with the degree of bubble generation in the cleaning tank 101. Further, in the present embodiment, the control unit 117 constitutes a plurality of times of detection of the abnormality of the foam which is initially performed in the cleaning process, and estimates the bubble depending on the time and number of occurrences of the abnormality of the bubble. The above-mentioned structure is implemented by the above-described structure, in which the user can misuse the surfactant content, and the amount of surfactant is higher than g, depending on the amount of production, and the amount of water generated in the self-cleaning tank 101 and the defoaming process for supplying water to the washing tank 1〇1. When the agent is operated, the foam can be detected at a time when the foam is easily generated, and the foam can be prevented from overflowing from the water level detecting groove 108 and the like, so that the water leakage detecting portion 15 114 is actuated to make the dishwasher unusable. To improve reliability. Further, in the present embodiment, the air supply farm 120 for discharging the steam in the washing tank ι〇ι from the exhaust port 121, and the air supply passage connecting the air blowing device 12 and the washing tank 1 () 1 are additionally provided. 118. The control unit 117 is configured to detect the occurrence of abnormality of the foam at least once in the initial stage of the cleaning process, and when the difference in the measured bubble is often generated, the air blowing device 120 is operated at the time of the bubble detection. At the predetermined time, a defoaming process capable of draining the water from the washing tank 101 and supplying water to the washing tank 1〇1 is performed. By the above structure, the bubble flowing into the air supply passage m can be returned to the cleaning tank 1〇1 to avoid the decrease of the air supply volume caused by the inflow of the foam, that is, the drying performance can be avoided, and the drying performance can be avoided. It is possible to prevent the foam from adhering to the charging portion of the airbrush pen i2, etc., resulting in a decrease in electrical insulation performance. Further, in the present embodiment, the bubble detecting unit is configured to increase or decrease the operation time of the air-conditioner 120 that operates when the bubble has abnormally occurred, depending on the time and number of times the abnormality of the bubble is detected. According to the above configuration, if the time and number of occurrences of the abnormality of the bubble are small, it is estimated that the amount of generation of the foam is large, and the air supply time of the air supply of 12 可 can be increased. On the other hand, if the time and number of occurrences of the abnormality of the bubble are large, it is estimated that the amount of generation of the foam is small, and the operation of the air blowing device 12 can be reduced. Therefore, the amount of foam which has flowed into the air supply passage 118 can be surely flown back to the washing tank 101, and the amount of blown air caused by the inflow of the foam can be prevented from being lowered. That is, the deterioration of the drying performance can be surely avoided. Further, it is possible to surely prevent the foam from adhering to the charging portion of the air blowing device 120 or the like, resulting in deterioration of electrical insulation performance. In addition, in the present embodiment, although the number of repetitions C of the defoaming procedure is determined in comparison with the time required for the pump 116 to be turned off to the start of the switch 11 and the predetermined time, the present invention is not limited thereto, if the corresponding switch 110 is started before If the time is long and the number of repetitions C is changed, the number of times of bubble detection may be one. As described above, the cleaning apparatus of the present invention can detect the large amount of bubble/bundle generation with a simple structure, and can also efficiently reduce the foam which has been produced. Further, it is possible to prevent the operation of the water leakage detecting unit from being stopped, and to ensure the electrical insulation performance of the parts such as the air supply portion connected to the cleaning tank, and to have safety and reliability. Moreover, it is not limited to a dishwasher, but is also applicable to various machines such as a washing machine that can generate foam. 23 200913952 L.
