Description of the Invention (1) [Technical Field] The present invention relates to a drum-type washing machine in which a rotatable drum-type rotary tank is disposed inside a water tank. [Conventional technology] In the conventional drum type washing machine, a low-foaming lotion (10 w f 〇 a m i n g t y p e) that tends to use less foam during the washing process is more likely to be used. This is due to the following reasons. In other words, in the drum type washing machine, the rotary tub is rotated at a relatively low speed, so that the laundry in the rotary tub is dropped from the top to wash it (pat). At this time, if a lot of foam is generated in the rotating tank, the impact of falling laundry will be alleviated and the washing effect will be reduced. In addition, if a large amount of foam is generated during the washing process, a large amount of foam will enter between the rotation tank and the water tank during the dehydration process, which will hinder the rotation of the rotation tank. Then the rotation speed of the rotating tank cannot be increased, and the rinsing product cannot be completely dehydrated, or the rotation of the rotating tank can be stopped halfway. Compared with low-foaming lotions, non-low-foaming lotions are generally Synthetic lotions are generally easier to obtain, more versatile, and less expensive. Therefore, it is desired to develop a drum type washing machine which can use a general synthetic detergent.

FIG. 11 is a flowchart of various processes performed during the washing cycle. FIG. 12 is a diagram showing the operation timing of the water supply tank 54 and the rotating tank 10 for each process of the washing cycle. FIG. 13 is a diagram showing A flowchart of each process performed during the water supply operation during the washing cycle. As shown in these figures, the water supply operation is initially performed during the washing cycle (step S 3 1). This water supply operation is performed by opening the water supply valve 54 (step S 3 1 1). As a result, the tap water is allowed to pass through the pipe 65 and the water injection tank 61 to be supplied into the water tank 8 together with the cleaning agent. Next, the control circuit 9 2 will read the output frequency of the pressure sensor 4 7 to determine whether it is below the threshold (X (k Η ζ) (Steps This paper size applies the Chinese National Standard (CNS) Α4 specification (210X297 Mm) _ 20-丨 " ^ ----- # 1 ^ II (Please read the notes on the back before filling out this page), 11 Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives 554115 Intellectual Property of Ministry of Economic Affairs A7 B7 printed by the Bureau's Consumer Cooperatives V. Invention Description (18) s 3 1 2). The threshold 値 X 'is obtained experimentally based on the state of foam generation in the rotating tank 10 and the output of the pressure sensor 47. A state in which the output frequency of the pressure sensor 47 is below the critical value 値 X indicates that there is an abnormally large amount of bubble generation. In this state of excessive foaming, for example, when the general synthetic lotion is used in the “low foaming lotion” mode, it may occur if the amount of the lotion is wrong. When the output frequency of the pressure sensor 47 is larger than the critical value 値 X (N0), that is, when there is no abnormality in the generation state of the bubble 控制, the control loop 92 will move to step S3 13 and will sense based on the water level The output of the device 49 determines whether the water level in the water tank 8 has reached the starting water level of the preliminary stirring operation. When the starting water level is reached (Y E S), it will move to step S 3 1 4 and start the preliminary stirring operation. The preliminary stirring operation is an operation in which tap water and a lotion are mixed together by intermittently and rotationally driving the rotary tank 10. Specifically, as shown in FIG. 11, the motor 16 is driven in the forward direction at a rotation speed of 50 (rpm) for 5 seconds, stopped for 2 seconds, and then reversed at a rotation speed of 50 (rpm). Drive in the direction for 5 seconds, stop for 2 seconds, and repeat this action. Next, the control circuit 9 2 will use step S 3 1 5 to determine whether the water level in the water tank 8 has reached the set water level. When the set water level is reached (YES), the pre-stirring action is ended and the water supply valve 5 4 is closed. And the water supply operation is ended (steps S 3 16 and S 3 1 7). When the set water level is not reached, the process returns to step S 3 1 2. In contrast, in step S 3 1 2, when the output frequency of the pressure sensor 47 is below the critical value 値 X (YES), it will move to the step.

Once the water supply operation is terminated, the control loop 9 2 will cause the door lock device to lock the door 2 into a locked state (step S 3 2). Next, the control loop 9 2 , The rotating groove 10 will be continuously rotated in the forward and reverse directions (stirring action). Specifically, as shown in FIG. 12, the motor 16 is rotated forward at a rotational speed of 60 (^ P m). Drive for 20 seconds in the direction, stop for 2 seconds, drive for 20 seconds in the reverse direction, stop for 2 seconds, and repeat the action. Next, control the loop 9 2 to determine whether the output frequency of the pressure sensor 47 is critical. z or less (step S 3 4). In the pressure sensor economy department The output of the Intellectual Property Bureau employee consumer cooperative printed 4 7 is below the threshold 値 z, which shows the state where the bubble 溢出 will overflow from the entrance 5 when the door 2 is opened. The threshold 値 z is set to be higher than the above threshold値 X is larger 値. When the output frequency of the pressure sensor 47 is larger than the critical 値 z (N0), even if the door 2 is opened, the bubble will not overflow from the entrance 5 and the door lock device 1 is judged The release operation of 0 0 can be performed and the flag F is set to "0" (step S 3 5). On the other hand, when the output frequency of the pressure sensor 47 is less than the threshold 値 z (YE S), the door 2 When it is opened, the bubble may overflow from the entrance 5 and it is judged that the unlocking operation of the door lock device 100 cannot be performed and the flag F is set to "1" (step S 3 6). Next, the control circuit 92, To determine whether the output frequency of the pressure sensor 47 is below the threshold 値 X (step S 3 7). And if the output frequency of the pressure sensor 47 is greater than the threshold 値 X (N 0), it will move to step 5 3 9.

Description of the invention (20) (Please read the precautions on the back before filling this page) Situation (N〇), will drain water The valve 19 is opened for a predetermined time to discharge a part of the water in the water tank 8 (step S 3 8), and then moves to step S 3 9. This allows the height of the bubble to be lowered, so that it can be in the water tank 8 Increasing the space where foam can be accommodated can reduce the amount of foam that can be caused by washing. Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs. Figure 14 shows the relationship between the elapsed time after starting the stirring operation and the output of the pressure sensor 47. In FIG. 14, the states where the amount of bubble generation is large, the normal state, and the state where there are few are shown by the curves D1, D2, and D3, respectively. Accompanied by the stirring action, foaming gradually occurs in the rotating tank 10. In a state where the amount of foaming is large, the foaming will reach the vicinity of the opening 4 2 (connection port 3 8) in the duct 30 a early after the stirring operation, and the pressure in the airlock 37 will start. Rises, and the output of the pressure sensor 47 will start to decrease in response to this. On the other hand, when the amount of bubble generation is normal, the output of the pressure sensor 47 will start to decrease after a period of time after the stirring operation starts. In a state where the amount of bubble generation is small, even if stirring is performed, the bubble generation hardly reaches the vicinity of the opening portion 4 2 in the duct 30a, so the output of the pressure sensor 47 is hardly changed. In step S 39, the control loop 92 is used to judge whether there is an operation of the start switch 69 to indicate a pause. When the start switch 6 9 is not operated, it is judged whether the stirring operation time has elapsed (step S 4 0), and when it has not elapsed (N ◦), it will move to step S 3 4 and repeat the above process.

Next, at step S4, it is determined whether the flag F is "1". When the flag F is "0" (N 0), the door lock is released (step S 4 5), and in step S 4 6 it waits for the start button 6 9 to be operated again. On the other hand, when the flag F is "1" (S 4 4: YES), the process proceeds to step S 46. 4 In this case, the user cannot open the door 2 even if he wants to throw in the laundry during the stirring operation. Thereby, it is possible to prevent in advance that the door portion 2 is opened to allow the bubble to overflow from the entrance 5 in a state where the amount of bubble is large in the rotation groove 10. At this time, as shown in FIG. 15, the control circuit 9 2 displays an error code “E: — d” on the display portion 8 1. This error code indicates that the door lock cannot be unlocked due to the large amount of bubbles generated in the rotating groove 10.

(Step S 5 2). Motor 1 6 then It is driven at the same timing as the stirring action of the washing stroke. Once the stirring action is started, the control circuit 92 determines whether the output frequency of the pressure sensor 47 is below a threshold 値 γ (k Η z) (step S 5 3). The threshold 値 y is approximately the same as the threshold 値 X, or is set to be slightly larger than the threshold 値 X. In the case where the output of the pressure sensor 47 is larger than the threshold 値 y (N0), Step S 54 will determine whether the stirring time has elapsed. Moreover, when the stirring time has not elapsed (NO), it will return to step S 5 3, and when the stirring time has elapsed (YES), the motor 1 will be stopped.

The heater 2 8 will be energized and the water supply valves 3 6 and 5 2 will be opened. As a result, the humid air in the rotary groove 10 passes through the hole portion 1 1 as shown by the arrow A in FIG. 1 and FIG. 5 and is sucked into the duct 30 a from the suction port 31. As shown by arrow B in Figs. 1 and 5, water is sprayed into the duct 30 a from the water jet 3 4 a. Further, as indicated by an arrow C in Fig. 7, water is supplied from the connection port 40 into the duct 30a.

FIG. 17 is a flowchart showing the final drainage operation. First, the control circuit 92 will open the drainage valve 19 to discharge the water in the rinsing tank 8 (step S 2 0 1). Next, the control circuit 92 determines whether the water level in the water tank 8 is below the reset water level (step S 2 0 2). This reset water level represents the lowest water level that can be detected by the water level sensor 49. When the water level in the water tank 8 is below the reset water level (Y ES), the water supply valve 5 2 is opened to start the water supply to the air lock 37 (step S203). Next, the control circuit 92 reads the output frequency of the pressure sensor 47 to determine whether it is below the critical threshold ρ (step S 2 0 4). This step S 2 0 4 is used to check whether there is cotton wool stuck in the connection port 38. For example, during the previous drying operation, the cotton wool discharged from the laundry was plugged into the airlock 37 when the connection port 38 was connected, and the water W was accumulated in the airlock 37 as shown in FIG. 18 .

Furthermore, when the state of the output of the pressure sensor 47 is below the critical threshold for five seconds (step S208: YES), it is determined that cotton wool is clogged in the connection port 38, and the situation is stored (step S20) 9 ). Furthermore, in step S206, the water supply valve 52 is closed to stop the water supply to the airlock 37. After the final drainage operation is terminated, the rinsing and washing process is completed, and then the second dehydration process and the drying process are sequentially performed.
