Description of the Invention: The present invention relates to a drum type washing machine that rotationally drives a rotating drum to wash laundry clothes contained in the rotating drum. C. Prior Art 3 Background of the Invention The structure of a conventional drum type washing machine or dryer is to drive the rotation of the motor to the drum pulley by a belt to drive the rotary drum to rotate forward or reverse for washing or drying. Therefore, in the conventional clothes dryer, when the belt for conveying the rotation of the motor is broken, or when the belt is off, the hot air will be concentratedly blown on the inside of the rotary drum, and thus the clothes on the clothes are discolored or Charging, the worst can also cause clothing to catch fire. In order to solve the above-mentioned problems, Japanese Laid-Open Patent Publication No. Hei 8-215493 (hereinafter referred to as "Patent Document"), or JP-A-H99-99 (hereinafter referred to as "Patent Document 2") is taken as an example, and the disclosed clothes are disclosed. The structure of the machine is stopped when the number of rotations of the motor reaches a constant number of rotations (〇FF). The number of pulses when the motor is read (4) stops, and the time from the line to the stop is abnormal when the value exceeds the set value. Invitation to report. For example, Japanese Laid-Open Patent Publication No. 294 (hereinafter referred to as "Patent Document 3") discloses a dryer for controlling an electric motor with a predetermined number of rotations, and the like is carried out by the following method. Anomaly detection. That is, 201217599, according to the publication, when it is detected that the motor is rotated by the abnormal number of rotations exceeding the predetermined number of rotations, the number of rotations of the motor is returned to the predetermined number of rotations after the number of rotations after the predetermined number of rotations has been detected, and the belt is broken. Further, if the number of rotations of the motor does not return to the predetermined number of rotations, it is determined that the control of the motor is abnormal and an abnormality alarm is issued. At this time, the detection methods of Patent Document 1 and Patent Document 2 can effectively detect the abnormality of the belt when the dryer performs the drying operation. However, in the dehydration operation during the washing operation at a higher speed than during the drying operation, if the abnormal operation of the motor is detected abnormally, it takes time to wait for the motor to stop. As a result, it takes time to detect the abnormality of the washing machine, so that safety or reliability arises. Moreover, the detection method of Patent Document 3 drives the motor with an abnormal number of rotations and a predetermined time, so that in the dehydration operation of the washing machine which rotates at a higher speed during the drying operation of the dryer, if the drying operation is performed When the same method detects an abnormality, the rotation sound of the motor forms noise, causing the user to be uneasy. Further, if the motor is driven continuously by the number of abnormal rotations and the predetermined time, there is a problem such as a motor failure. Further, when the belt is broken or the belt is detached, the rotation of the rotating drum is stopped. After the motor is stopped, even if the motor is stopped, the rotating drum is actually rotated. However, the control unit of the dryer determines that the rotary drum has stopped according to the stop of the motor, thereby releasing the locked state of the cover. That is, there is a problem that the user may accidentally open the cover before the rotating drum stops. [Summary Content 3

In general, between the one rotation of the rotor of the motor 5, three positions are inspected at the time of the 201217599 measuring portion 22a. 22b and 22c respectively output pulses at intervals of 12 degrees of electrical angle. The control unit 17 detects the time when the signal state of any of the three position detecting units 22a, 22b, and 22c changes. The control unit 17 detects the detected state. The signals of the position detecting sections 22a, 22b, and 22c change the on/off combination of the first conversion element 2 to the sixth conversion t1 24f. Thereby, the motor phase terminal, the v-phase terminal, and the W-phase terminal are set to be positive. The voltage and zero voltage 'open three states. In this way, the rotor of the motor 5 can be rotated by the magnetic field generated after the second winding 5a, the second winding 5b, and the third winding 5c provided on the stator of the motor 5 are energized. Also, the first conversion element 2 of the inverter 24 4a, the third conversion element 24 (;, and the fifth conversion element 24e are respectively subjected to pulse width modulation (pwM) control. Specifically, the control unit 17 controls the high and low energization ratios by, for example, a repetition frequency of 1 kHz. In order to control the number of revolutions of the rotor of the motor 5. In other words, the control unit 17 detects a period in which the signal state of any of the three position detecting units 22a, 22b, and 22c changes, and calculates the number of revolutions of the rotor of the motor 5 based on the detected period. Then, based on the calculated number of rotations, the first conversion element 24a, the third conversion element 24c, and the fifth conversion element 24e of the inverter 24 are PWM-controlled so that the number of rotations of the motor 5 reaches the set number of rotations. 'When the rotational speed of the rotary drum 1 is to be increased, the first to sixth conversion elements 24a to 24f of the inverter 24 are PWM-controlled to generate a torque in the rotational direction. Conversely, the rotational speed of the rotary drum 1 is to be slowed down. In the case of 煞杇, the first conversion element 24a to the sixth conversion element 24f of the inverter 24 are PWM-controlled to generate torque in the opposite direction of the rotation direction. Thereby, the rotation speed of the rotary drum 1 can be freely controlled. Or Stopping (deceleration). As shown in Fig. 3, the commercial power source 26 of the control device 16 is connected by a DC power conversion device 27 such as a 10 201217599 diode bridge 27a, a smoothing capacitor 27b, 27c, and the like. The inverter 24 is configured to constitute the control device 16 of the drum type washing machine of the present embodiment. The configuration of the above-described control device 16 is only an example, and the structure of the brushless DC motor 5 is changed. The structure display unit for setting the operation progress of the drum type washing machine of the present embodiment will be described below with reference to Fig. 4 . Fig. 4 is a schematic view showing the operation display portion of the drum type washing machine of the present embodiment. Here, the operation display unit has at least the input setting unit 18 and the display unit 19. As shown in FIG. 4, the input setting unit 18 of the operation display unit has a washing time setting switch 18a' for setting the washing time, a washing time setting switch 18b for setting the number of washing times, and one for The dehydration time setting switch 18c for setting the dehydration time, a drying time setting switch l8d for setting the drying time, a process setting switch I8e, a start/stop switch 18f, a power-on switch 18g, a power-off switch I8h, etc. . Further, the operation display unit 19 includes a washing time display unit 19a, a washing time display unit 191, a dehydration time display unit 19c, a drying time display unit 19d, a process setting display unit 19e, and the like. At this time, the control unit 17 responds to the setting of the input setting unit 18 of the display unit (for example, the washing time setting switch 18a is turned on and the power-on switch 18g is turned on), and the lid locking device 12 shown in Fig. 1 is used. The lid body 11 is locked to be in a closed state or unlocked. Further, when the cover locking device 12 locks the 201217599 lid body 11, the washing machine can be started to operate. Further, as will be described later, the control unit π controls the lid lock device 12 to continuously lock the lid body 11 in the closed state by the setting of the input setting unit 18 during the operation of the washing machine, for example, by the start/stop switch 18f. Further, after the operation of the washing machine is completed, the lid lock mechanism 12 is still controlled to continue to set the lid body to the closed state. The operation of the drum type washing machine of the present embodiment can be controlled by the control of the control device described above. The present invention is directed to the control action until the break of the debt measuring belt or when the belt is detached, which will be described below using Figs. 5 to 7 . In addition, the control action after the belt break or belt detachment is detected is illustrated in Figures 8 and 9. Fig. 5 is a first flow chart for explaining the control of the drum type washing machine of the present embodiment until the belt is broken and the belt is peeled off. As shown in Fig. 5, first, when the operation of the washing machine is to be started (step si〇〇), the power-on switch 18g of the input setting unit 18 shown in Fig. 4 is turned on (step S101). Next, it is judged whether or not the start of the input setting unit 18 is turned on (step S102). At this time, if the start/pause switch 18f is turned off (step s] 〇 2 N 〇), the standby/pause switch 18f is pressed until it is pressed. Further, when the start/pause switch 18f of the open input setting unit 18 is pressed (Yes in step S12), the laundry stroke starts. At this time, the lid body 11 is controlled by the lid lock device 12 to be locked to be in a closed state (step S10). Next, it is determined whether or not the motor 5 has started the rotation operation (step S104). At 12 201217599, if the motor 5 does not start the rotation (N〇 in step sl4), it enters the standby state.
Is而，電動機5業已啟動旋轉動作時（步驟sl〇42Yes)， 判斷電動機5旋轉動作中是否進行煞停動作（步驟sl〇5^此 時，若未進行煞停動作（步驟S1052N〇)，則進入待機狀態。 其次，業已進行煞停動作時（步驟81〇5之力8),判斷煞 停動作開始時位置檢測部22a、22b、22c偵測到之電動機旋 轉數是否為第1預定旋轉數（例如750rpm(Rev〇luti〇ns per minute))以上（步驟si〇6)。此時，若電動機5之旋轉數未達第 1預疋5疋轉數(步驟S106之No)，則進入待機狀態。 繼之，電動機5之旋轉數為第丨預定旋轉數以上時(步驟 S106之Yes)，判斷煞停動作開始至停止為止電動機5之停止 時間疋否較第1預定時間（例如丨秒)短（步驟S1〇7)。此時，若 煞停動作開始至停止為止電動機5之停止時間較第丨預定時 間長(步驟S107之No) ’不會判定皮帶脫落•皮帶斷裂，並 繼續後續行程(步驟S丨〇 9)。總而言之係因為皮帶未斷裂時， 由於電動機與旋轉滾筒藉由皮帶連結，故即使煞停電動 機，在停止之前仍須一些時間。 此外，煞停動作開始至停止為止電動機5之停止時間較 第1預定時間（例如丨秒)短時(步驟sl07iYes)，偵測為皮帶 脫落•皮帶斷裂（步驟S108)。 藉此，在判定皮帶斷裂、或皮帶脫離滾筒帶輪之皮帶 脫落上更為容易。因此’無須為偵測皮帶斷裂•皮帶脫落 追加特別練或延長行程時間。如此-來，可精確福測皮 13 201217599 帶脫落或皮帶斷裂，實現可靠性佳之滾筒式洗衣機。 另’上述第1預定時間，宜依煞停開始時電動機5之旋 轉數變化控制。舉例言之，煞停開始時電動機5之旋轉數未 達第1預定旋轉數1350rpm時，第1預定時間設為1秒。又， 煞停開始時電動機之旋轉數為第i預定旋轉數1350rpm以上 且未達1650rPm時，第1預定時間設為1.5秒。進而，煞停開 始時電動機5之旋轉數為第丨預定旋轉數165〇rpm以上時’第 1預定時間設為2秒。 總而言之，設定煞停開始時電動機5之旋轉數較第丨預 定旋轉數大時之第1預定時間，長於較第丨預定旋轉數小 時’藉此可使㈣皮帶斷裂·皮帶脫落之偵測精確度更加 提升。 但第1預定時間或旋轉數當然非以上述範圍之數值為 限在不〜響洗衣機之偵測動作等之情形下做任何設定皆 可。 本發月之實施型態中，對於债測皮帶斷裂時或皮帶脫 落時之其他控制動作，利用第6圖說明如下。 第6圖係說月本實施型態之滾筒式洗衣機至傾測皮帶 斷裂與皮帶脫落為止之控制之第2流程圖。另，如第6圖所 τ v娜⑽至步驟s1Q4因與第頂所示之第1流程圖相 同，故省略說明。 總而δ之’如第6 Ιϋ所π，電動機5啟動旋轉動作時(步 驟S104之Yes) ’判斷位罟扒 直後碉部22a、22b、22c偵測到之電 動機旋轉數是否為第9箱中# 不z很疋$疋轉數（例如2〇〇〇rpm)以上（步驟 14 201217599 。此時，若電動機5之旋轉數未達第2預定旋轉數（步禪 SUO之N。），則不會判定皮帶脫落•皮帶斷裂，並繼 行程（步驟S112)。 此外，電動機5之旋轉數為第2預定旋轉數以上時(步驟 SUO之YesH貞測為皮帶脫落.皮帶斷裂（步驟s叫。 藉此，控制部更容易於電動機之旋轉數大於第2預定旋 轉數時’判定皮帶斷裂、或皮帶脫離滚筒帶輪之皮帶脫落。 如此-來’可辨別電動機高速旋轉造成之故障、抑或未發 生皮帶斷裂或皮帶脫落之正常運轉時電動機之旋轉數，從 而防止偵測時誤認為皮帶斷裂•皮帶脫落。 本發明之實施型態中，對於債測皮帶斷裂時或皮帶脫 落時之其他進一步之控制動作，利用第7圖說明如下。 第7圖係說明本實施型態之滾筒式洗衣機至偵測皮帶 斷裂與皮帶脫落為止之控制之第3流程圖。另，如第7圖所 示，步驟S1〇0至步驟S104因與第5圖或第6圖所示之流程圖 相同，故省略說明。 總而言之’如第7圖所示’電動機5啟動旋轉動作時(步 驟S104之Yes)，判斷用以控制並驅動旋轉滚則旋轉之電動 機5之旋轉數是否按第3預定旋轉數(例如30〜60啊(旋轉 滾筒比旋轉數))控制（步驟Sll3)e此時，若電動機5之旋轉 數非按第3預定旋轉數控制（步驟SU3之N。），則進入待機狀 態。 其次，旋轉滾筒1之旋轉數經電動機控制為第3預定旋 轉數時（步驟S1B之Yes)，顺位置檢測部m ' 22b ' 22c 15 201217599 偵測到之電動機5之旋轉數是否為第4預定旋轉數（例如 lOOOrpm)以上（步驟S114)。此時，若電動機5之旋轉數未達 第4預定旋轉數(步驟S114之No)，則不會判定皮帶脫落•皮 帶斷裂，並繼續依運轉進程進行各洗衣行程（步驟S116)。 此外，電動機5之旋轉數為第4預定旋轉數以上時（步驟 S114之Yes)，偵測為皮帶脫落.皮帶斷裂（步驟SU5)。 藉此，於電動機5欲以第3預定旋轉數控制旋轉滾筒1旋 轉時，若控制部偵測電動機5旋轉高於第4預定旋轉數，則 判定為皮帶斷裂、或皮帶脫離滾筒帶輪之皮帶脫落。如此 一來，可增加偵測皮帶斷裂•皮帶脫落之機會。 另，用以偵測皮帶斷裂•皮帶脫落之電動機5之第4預 定旋轉數，宜依據用以控制並驅動旋轉滾筒1旋轉之電動機 5之第3預定旋轉數改變。舉例言之，除上述外，用以控制 並驅動旋轉滾筒1旋轉之電動機5之第3預定旋轉數為60〜 150rpm時，電動機5之第4預定旋轉數設為1200rpm。又，用 以控制並驅動旋轉滾筒1旋轉之電動機5之第3預定旋轉數 為150〜750rpm時，電動機5之第4預定旋轉數設為 1500rpm。進而，用以控制並驅動旋轉滾筒1旋轉之電動機5 之第3預定旋轉數為750rpm以上時，電動機5之第4預定旋轉 數設為2000rpm。 但，僅確保隨著用以控制並驅動旋轉滾筒1旋轉之電動 機5之第3預定旋轉數增加，電動機5之第4預定旋轉數亦增 加之設定關係，當然非以上述範圍之數值為限，且在不影 響洗衣機之偵測動作等之情形下做任何設定皆可。 16 201217599 藉此，可在各種洗衣行程中，增加對用以使旋轉滾筒 旋轉之電動機之所有旋轉數偵測皮帶斷裂•皮帶脫落之機 會。 針對由第5圖至第7圖之控制動作偵測出皮帶斷裂•皮 帶脫落以後之控制動作，利用第8圖與第9圖說明如下。另， 第8圖及第9圖中，為幫助理解第5圖至第7圖所說明之偵測 皮帶斷裂•皮帶脫落時之判斷，有部分重複記載。 第8圖係說明本實施型態之滾筒式洗衣機偵測出皮帶 斷裂與皮帶脫落以後之控制之第4流程圖。 如第8圖所示，開始進行滚筒式洗衣機偵測出皮帶斷 裂·皮帶脫落以後之控制（步驟S200)。 其次，判斷是否偵測出皮帶斷裂•皮帶脫落（步驟 S201)。此時，若未偵測出皮帶斷裂•皮帶脫落（步驟S201 之No)，則進入待機狀態。 繼之，偵測出皮帶斷裂.皮帶脫落時(步驟S201之Yes)， 對使用者發出皮帶斷裂·皮帶脫落之異常警報(步驟S202)。 此時，警示使用者之方法，舉例言之有：利用蜂鳴器等發 聲器警示、利用顯示部19之閃爍等警示、利用故障模式等 錯誤碼顯示警示等。 繼之，偵測皮帶斷裂•皮帶脫落後，判定第2預定時間 (例如5分鐘）是否已過（步驟S203)。接著，若第2預定時間尚 未經過(步驟S203之No)，則進入待機狀態直到第2預定時間 已過。此時，蓋鎖定裝置12於第2預定時間經過前，持續鎖 定蓋體11形成關閉狀態。此係為於皮帶斷裂•皮帶脫落後， 17 201217599 等待旋轉滚筒1之慣性旋轉停止。 繼之，於第2預定時間過後（步驟S203之Yes)，蓋鎖定裝 置12進行蓋鎖定解除控制（步驟S204)。因此，可打開蓋體 11，由旋轉滾筒1内取出洗滌衣物等。 總而言之，如第8圖所示，控制部於偵測出皮帶斷裂. 皮帶脫落時，進行一維持以蓋鎖定裝置12鎖定蓋體之狀態 直到第2預定時間經過，並於第2預定時間過後解除蓋鎖定 裝置對蓋體之鎖定狀態之控制。因此，於皮帶斷裂•皮帶 脫落時，即使中斷洗衣行程之洗滌運轉動作，仍可鎖定蓋 體直到旋轉滾筒之旋轉停止。如此一來，可預防蓋體於旋 轉滾筒旋轉中打開之危險狀態，並可實現安全又可靠之滚 筒式洗衣機。 對於本發明之實施型態中，偵測出皮帶斷裂或皮帶脫 落以後之其他控制動作，利用第9圖說明如下。 第9圖係說明本實施型態之滚筒式洗衣機偵測出皮帶 斷裂與皮帶脫落以後之控制之第5流程圖。另，如第9圖所 示，步驟S200至步驟S202係與第8圖所示之流程圖相同，故 省略說明。 總而言之，如第9圖所示，偵測出皮帶斷裂•皮帶脫落 時(步驟S201之Yes)，對使用者發出皮帶斷裂•皮帶脫落之 異常警報(步驟S202)。 其次，按下輸入設定部18之電源關閉開關18h後，判斷 是否業已開啟（步驟S205)。 繼之，輸入設定部18之電源關閉開關18h開啟時（步驟When the motor 5 has started the rotation operation (step sls42Yes), it is determined whether or not the vehicle 5 is in the operation of the rotation of the motor 5 (step sl1〇5), if the suspension operation is not performed (step S1052N〇), When the stop operation is performed (the force 8 of step 81〇5), it is determined whether the number of motor rotations detected by the position detecting units 22a, 22b, and 22c at the start of the stop operation is the first predetermined number of rotations. (for example, 750 rpm (Rev〇luti〇ns per minute)) or more (step si〇6). At this time, if the number of rotations of the motor 5 does not reach the first predetermined number of revolutions (No in step S106), the operation waits. Then, when the number of rotations of the motor 5 is equal to or greater than the predetermined number of rotations (Yes in step S106), it is determined whether the stop time of the motor 5 is less than the first predetermined time (for example, leap seconds) until the stop operation starts and stops. Short (step S1〇7). At this time, if the stop operation starts and stops until the stop time of the motor 5 is longer than the predetermined time (No in step S107), 'the belt does not fall off, the belt is broken, and the subsequent stroke is continued. (Step S丨〇9). In summary Because the belt is not broken, since the motor and the rotating drum are connected by the belt, even if the motor is stopped, it takes some time before stopping. In addition, the stopping time of the motor 5 is shorter than the first predetermined time until the stopping operation starts to stop. (for example, leap second) is short (step sl07iYes), and it is detected that the belt is detached and the belt is broken (step S108). Therefore, it is easier to determine that the belt is broken or the belt is detached from the belt of the drum pulley. In order to detect belt breakage and belt drop, special training or extended travel time can be added. In this way, it can be used to accurately measure the leather 13 201217599 belt off or belt breakage to achieve a reliable drum type washing machine. The rotation number change control of the motor 5 is started by the start of the stop. For example, when the number of rotations of the motor 5 at the start of the stop is less than the first predetermined number of rotations of 1350 rpm, the first predetermined time is set to 1 second. When the number of rotations of the motor is the first predetermined number of rotations of 1350 rpm and less than 1650 rPm, the first predetermined time is set to 1.5 seconds. When the number of rotations of the motive 5 is 165 rpm or more, the first predetermined time is set to 2 seconds. In summary, the first predetermined time when the number of rotations of the motor 5 at the start of the pause is larger than the predetermined number of rotations is set. The time is longer than the predetermined rotation of the second cymbal 'by this, so that the detection accuracy of the (four) belt rupture and belt detachment is further improved. However, the first predetermined time or the number of rotations is of course not limited to the value of the above range. In the case of the detection operation of the washing machine, etc., any setting can be made. In the implementation mode of this month, the other control actions when the debt measuring belt is broken or the belt is detached are explained as follows using FIG. Fig. 6 is a second flow chart showing the control of the drum type washing machine of the monthly embodiment to the control of the breakage of the tilting belt and the fall of the belt. Further, as shown in Fig. 6, τ v Na (10) to step s1Q4 are the same as the first flowchart shown in the top, and therefore the description thereof will be omitted. When the motor 5 starts the rotation operation (Yes in step S104), it is determined that the number of motor rotations detected by the rear squat portions 22a, 22b, and 22c is the ninth box. #不z很疋$疋转数 (for example, 2〇〇〇rpm) or more (Step 14 201217599. At this time, if the number of rotations of the motor 5 does not reach the second predetermined number of rotations (N of the step SUO), then It is determined that the belt is detached and the belt is broken, and the stroke is continued (step S112). When the number of rotations of the motor 5 is equal to or greater than the second predetermined number of rotations (YesH of step SUO is measured as the belt is detached. The belt is broken (step s is called. Therefore, the control unit can more easily determine that the belt is broken or the belt is detached from the belt pulley when the number of rotations of the motor is greater than the second predetermined number of rotations. Thus, the fault can be discerned by the high-speed rotation of the motor, or the belt does not occur. The number of rotations of the motor during normal operation of the break or the belt is detached, thereby preventing the belt from being broken at the time of detection. The belt is detached. In the embodiment of the present invention, when the debt measuring belt is broken or the belt is detached, the other one is further The control operation will be described below with reference to Fig. 7. Fig. 7 is a third flow chart for explaining the control of the drum type washing machine of the present embodiment to detect the breakage of the belt and the fall of the belt. Further, as shown in Fig. 7, Since the steps S1 to 0 to S104 are the same as those of the flowchart shown in Fig. 5 or Fig. 6, the description is omitted. In the following, "when the motor 5 starts the rotation operation as shown in Fig. 7 (Yes in step S104), it is judged. Whether the number of rotations of the motor 5 for controlling and driving the rotary roller is controlled according to the third predetermined number of rotations (for example, 30 to 60 (rotational drum ratio of rotation number)) (step S11) e. At this time, if the rotation of the motor 5 When the number is not controlled by the third predetermined number of rotations (N of step SU3), the standby state is entered. Next, when the number of rotations of the rotary drum 1 is controlled by the motor to the third predetermined number of rotations (Yes of step S1B), the position detection is performed. The part m ' 22b ' 22c 15 201217599 detects whether the number of rotations of the motor 5 is equal to or greater than the fourth predetermined number of rotations (for example, 100 rpm) (step S114). At this time, if the number of rotations of the motor 5 does not reach the fourth predetermined number of rotations (No in step S114), it will not The belt is detached and the belt is broken, and the laundry stroke is continued in accordance with the progress of the operation (step S116). When the number of rotations of the motor 5 is equal to or greater than the fourth predetermined number of rotations (Yes in step S114), the belt is detected as a belt drop. When the motor 5 wants to control the rotation of the rotary drum 1 by the third predetermined number of rotations, if the control unit detects that the motor 5 is rotated higher than the fourth predetermined number of rotations, it is determined that the belt is broken or the belt is broken. The belt that is off the roller pulley is detached. This increases the chance of detecting belt breakage and belt detachment. Further, the fourth predetermined number of rotations of the motor 5 for detecting the belt breakage/belt drop is preferably changed in accordance with the third predetermined number of rotations of the motor 5 for controlling and driving the rotation of the rotary drum 1. For example, in addition to the above, when the third predetermined number of rotations of the motor 5 for controlling and driving the rotation of the rotary drum 1 is 60 to 150 rpm, the fourth predetermined number of rotations of the motor 5 is set to 1200 rpm. Further, when the third predetermined number of rotations of the motor 5 for controlling and driving the rotation of the rotary drum 1 is 150 to 750 rpm, the fourth predetermined number of rotations of the motor 5 is 1,500 rpm. Further, when the third predetermined number of rotations of the motor 5 for controlling and driving the rotation of the rotary drum 1 is 750 rpm or more, the fourth predetermined number of rotations of the motor 5 is set to 2000 rpm. However, it is only necessary to ensure that the third predetermined number of rotations of the motor 5 for controlling and driving the rotation of the rotary drum 1 increases, and the fourth predetermined number of rotations of the motor 5 also increases, which is of course not limited to the above range. And any setting can be made without affecting the detection action of the washing machine, etc. 16 201217599 By this, it is possible to increase the number of revolutions of the motor used to rotate the rotary drum to detect the breakage of the belt and the belt drop in various washing strokes. The control operation after the belt breakage and the belt detachment are detected by the control operation of Figs. 5 to 7 will be described below using Figs. 8 and 9. In addition, in Fig. 8 and Fig. 9, in order to help understand the judgment of the detection of the belt breakage/belt peeling described in Figs. 5 to 7, there are some repeated descriptions. Fig. 8 is a fourth flow chart for explaining the control of the drum type washing machine of the present embodiment after detecting the breakage of the belt and the fall of the belt. As shown in Fig. 8, the drum type washing machine starts the control after the belt breakage and the belt is detached (step S200). Next, it is judged whether or not the belt breakage is detected and the belt is detached (step S201). At this time, if the belt breakage/belt drop is not detected (No in step S201), the standby state is entered. Then, when the belt is broken and the belt is detached (Yes in step S201), an abnormality alarm of the belt breakage/belt drop is issued to the user (step S202). In this case, the method of alerting the user is, for example, an alarm such as a buzzer, a warning such as blinking of the display unit 19, an error code such as a failure mode, and the like. Then, after the belt breakage is detected and the belt is detached, it is determined whether or not the second predetermined time (e.g., 5 minutes) has elapsed (step S203). Then, if the second predetermined time has not elapsed (No in step S203), the standby state is entered until the second predetermined time has elapsed. At this time, the lid lock device 12 continues to lock the lid body 11 to a closed state before the second predetermined time elapses. This is for the belt to break. After the belt has fallen off, 17 201217599 waits for the inertia rotation of the rotating drum 1 to stop. Then, after the second predetermined time has elapsed (Yes in step S203), the lid lock device 12 performs the lid lock release control (step S204). Therefore, the lid body 11 can be opened, and the laundry or the like can be taken out from the rotary drum 1. In summary, as shown in Fig. 8, the control unit detects that the belt is broken. When the belt is detached, a state in which the cover locking device 12 locks the cover is maintained until the second predetermined time elapses, and is released after the second predetermined time. The cover locking device controls the locked state of the cover. Therefore, when the belt is broken and the belt is detached, the cover can be locked until the rotation of the rotary drum is stopped even if the washing operation of the washing stroke is interrupted. In this way, the dangerous state in which the cover body is opened in the rotation of the rotary drum can be prevented, and a safe and reliable drum type washing machine can be realized. In the embodiment of the present invention, other control actions after belt breakage or belt detachment are detected, which will be described below using Fig. 9. Fig. 9 is a fifth flow chart for explaining the control of the drum type washing machine of the present embodiment after detecting the breakage of the belt and the fall of the belt. Further, as shown in Fig. 9, steps S200 to S202 are the same as those of the flowchart shown in Fig. 8, and therefore the description thereof will be omitted. In summary, as shown in Fig. 9, when the belt breakage/belt drop is detected (Yes in step S201), an abnormality alarm of the belt breakage/belt drop is issued to the user (step S202). Next, after the power-off switch 18h of the input setting unit 18 is pressed, it is judged whether or not it has been turned on (step S205). Then, when the power-off switch 18h of the input setting unit 18 is turned on (step
18 201217599 S205之Yes)，未切斷洗衣機電源（未關閉），仍以蓋鎖定裝置 12維持蓋體11之關閉狀態（步驟S206)。 其次，偵測皮帶斷裂•皮帶脫落後，判斷第3預定時間 (例如5分鐘）是否已過（步驟S207)。 繼之，若第3預定時間尚未經過（步驟S2〇7之No)，則進 入待機狀態直到第3預定時間經過。此時’蓋鎖定裝置12於 第3預定時間經過前，繼續鎖定蓋體丨丨形成關閉狀態。此係 為於皮帶斷裂.皮帶脫落後，等待旋轉滾筒丨之慣性旋轉停 止。 其次’第3預定時間過後(步驟S207之Yes)，蓋鎖定裝置 12進行蓋鎖定解除控制（步驟S2〇8)。因此，可打開蓋體u， 由旋轉滾筒1内取出洗滌衣物等。 繼之，切斷洗衣機之電源（步驟S2〇9)。 又，輸入設定部18之電源關閉開關18h未開啟時（步驟 S205之No)，如第8圖之流程圖說明，偵測皮帶斷裂•皮帶 脫落後，判斷第2預定時間（例如5分鐘）是否已過（步驟 S203)。接著’若第2預定時間尚未經過（步驟S2〇3iN〇)， 則進入待機狀態直到第2預定時間經過。此時，蓋鎖定裝置 12於第2預定時間經過前，繼續鎖定蓋體⑽成關閉狀態。 此係為於皮帶斷裂•皮帶脫落後，等待旋轉滾筒1之慣性旋 轉停止。 其次’第2預定時間過後(步驟S203之Yes)，蓋鎖定裝置 12進打蓋鎖定解除控制（步驟S2〇4)。因此，可打開蓋體u， 由旋轉滾筒1内取出洗滌衣物等。 19 201217599 總而言之，如第9圖所示之設定，偵測出皮帶斷裂•皮 帶脫落時，即使使用者進行切斷電源之設定，仍維持電源 開啟狀態直到第3預定時間經過，並於第3預定時間過後切 斷電源。藉此，可維持蓋鎖定裝置之鎖定狀態直到第3預定 時間經過。因此，洗衣行程令，即使欲切斷電源中斷運轉 動作，在第3預定時間經過前仍鎖定蓋體直到旋轉滾筒停止 旋轉。如此一來，假如突然斷電，亦可預防蓋體於旋轉滾 筒旋轉中打開之危險狀態，從而可實現安全又可靠之滾筒 式洗衣機。 另，本實施型態於例中之說明，係將旋轉軸4沿略傾斜 方向設於旋轉滾筒1之旋轉中心，並使旋轉滚筒1之軸心方 向由正面側朝背面側向下傾斜配置，但並非以此為限。舉 例言之，亦可將旋轉軸4沿略水平方向（包含水平方向）設於 旋轉滾筒1之旋轉中心，並使旋轉滚筒1之軸心方向沿略水 平方向配置。 C圖式簡單說明3 第1圖係本發明實施型態之滾筒式洗衣機之截面圖。 第2圖係顯示該滾筒式洗衣機本體由背面視之時，水 槽、滾筒帶輪、電動機、皮帶之位置關係圖。 第3圖係該滾筒式洗衣機之控制裝置之方塊圖。 第4圖係說明該滚筒式洗衣機之操作顯示部之概略圖。 第5圖係說明該滾筒式洗衣機至偵測皮帶斷裂與皮帶 脫落為止之控制之第1流程圖。 第6圖係說明該滾筒式洗衣機至偵測皮帶斷裂與皮帶18 201217599 Yes on S205, the washing machine is not turned off (not turned off), and the lid locking device 12 is still kept in the closed state (step S206). Next, after the belt breakage is detected and the belt is detached, it is judged whether or not the third predetermined time (e.g., 5 minutes) has elapsed (step S207). Then, if the third predetermined time has not elapsed (No of the steps S2 to 7), the standby state is entered until the third predetermined time elapses. At this time, the cover locking device 12 continues to lock the lid body to a closed state before the passage of the third predetermined time. This is because the belt breaks. After the belt comes off, wait for the inertia rotation of the rotating drum to stop. Next, after the third predetermined time has elapsed (Yes in step S207), the lid lock device 12 performs the lid lock release control (step S2〇8). Therefore, the lid u can be opened, and the laundry or the like can be taken out from the inside of the rotary drum 1. Then, the power of the washing machine is turned off (step S2〇9). When the power-off switch 18h of the input setting unit 18 is not turned on (No in step S205), as shown in the flowchart of Fig. 8, it is determined whether the belt is broken or the belt is detached, and it is judged whether or not the second predetermined time (for example, 5 minutes) is Passed (step S203). Then, if the second predetermined time has not elapsed (step S2〇3iN〇), the standby state is entered until the second predetermined time elapses. At this time, the lid lock device 12 continues to lock the lid body (10) to the closed state before the second predetermined time elapses. This is for the belt to break. After the belt is detached, wait for the inertia rotation of the rotating drum 1 to stop. Next, after the second predetermined time has elapsed (Yes in step S203), the lid lock device 12 enters the lid lock release control (step S2〇4). Therefore, the lid u can be opened, and the laundry or the like can be taken out from the inside of the rotary drum 1. 19 201217599 In summary, as shown in Figure 9, when the belt is broken and the belt is detached, even if the user sets the power off, the power is turned on until the 3rd scheduled time elapses, and the 3rd scheduled time Turn off the power after the time has elapsed. Thereby, the locked state of the lid locking device can be maintained until the third predetermined time elapses. Therefore, the washing stroke command locks the lid until the rotating drum stops rotating even if the power supply interruption operation is interrupted until the third predetermined time elapses. In this way, if the power is suddenly turned off, the dangerous state in which the cover body is opened during the rotation of the rotary drum can be prevented, thereby realizing a safe and reliable drum type washing machine. In the present embodiment, the rotation shaft 4 is disposed at a center of rotation of the rotary drum 1 in a slightly inclined direction, and the axial direction of the rotary drum 1 is inclined downward from the front side toward the back side. But it is not limited to this. For example, the rotating shaft 4 may be disposed in the horizontal direction (including the horizontal direction) in the center of rotation of the rotary drum 1, and the axial direction of the rotary drum 1 may be arranged in a slightly horizontal direction.
