Description

[Technical field]

[0001] An embodiment of the present invention relates to a laundry machine having an emergency stop function and an emergency stop program for the laundry machine. [Background technology]

[0002] Laundry machines installed in coin laundry stores have an emergency stop (also called pause) function during operation. For example, the laundry machine may be paused when it is operated with a mobile phone in a laundry pocket, when laundry is forgotten to be put in (one sock remains in the bag or basket), or when a child is hiding in the laundry.

[0003] When such an incident occurred, customers would call the laundromat owner to find out the location of the hidden pause button and how to operate it, which resulted in a lot of time being wasted trying to shut down the laundry machines in an emergency. Furthermore, a technology has been proposed for home washing machines that allows the operation to be temporarily stopped as needed, and automatically resumes operation after a predetermined time has elapsed since the operation was temporarily stopped (for example, Patent Document 1).

[0008] Hereinafter, a laundry machine having an emergency stop function and an emergency stop program for the laundry machine according to an embodiment will be described with reference to the drawings. FIG. 1 is a front view of a laundry machine according to an embodiment. In FIG. 1, the laundry machine 10 has a cubic shape and has different heights depending on the washing capacity. For example, a large machine has a washing capacity of 35 kg and a drying capacity of 26 kg. A medium machine has a washing capacity of 27 kg and a drying capacity of 18 kg. A small machine has a washing capacity of 11 kg and a drying capacity of 15 kg. FIG. 1 illustrates a small laundry machine (size S). The laundry machine 10 has a washing add-on section 30 having an opening / closing door 20 for inserting laundry into a washing tub (see FIG. 3) provided therein, and an operation panel section 40 having a plurality of non-contact type operation selection switches and various display lamps.

[0009] The door 20 is provided with a handle 25, and the handle 25 is provided with a door lock mechanism (not shown) for locking the door 20 while the laundry operation of washing and drying or washing and drying is being performed. The center of the door 20 and its surrounding area are made of translucent glass, allowing the inside to be seen during the laundry operation. A fee slot 35 for paying the usage fee is provided at the upper right of the washing tub section 30. Although the fee slot 35 is shown as an example here, a mechanism for credit card payment or electronic money payment may also be provided.

[0010] 2 shows the detailed configuration of the operation panel of the laundry machine. Operation panel 40 is provided with a number of course buttons (wash / dry buttons 100, 110, wash button 120, and dry button 130). Above each of the course buttons 100-130, the usage fee, operating time, and capacity are displayed facing each button. For example, the wash / dry button 100 displays a capacity of 11 kg, a usage fee of 1200 yen, and a wash / dry time of 60 minutes. Similarly, the wash / dry button 110 displays a capacity of 6 kg, a usage fee of 1000 yen, and a wash / dry time of 50 minutes. The wash button 120 displays a washing capacity of 15 kg, a usage fee of 800 yen, and a wash time of 30 minutes. The dry button 110 displays a drying capacity of 11 kg, a usage fee of 100 yen, and a drying time of 10 minutes. The display of these components is controlled so that while the laundry machine is operating, the selected course lamp is displayed and the other course buttons are difficult to see or cannot be seen.

[0011] An arch-shaped flicker lamp 140 is provided on the left side of the operation panel unit 40 to indicate the paused or operating state of the laundry machine 10. Further to the left of that, a "voice navigation" button 150, a "drum wash" button 160, and an "emergency stop" button 170 are provided. The "voice navigation" button 150 is pressed when a user wishes to hear voice announcements such as the completion of each step of the laundry operation. The "drum wash" button 160 is pressed when a user wishes to have the washing tub cleaned before starting to use the laundry machine 10. These buttons are pressed as appropriate according to the user's wishes. In this embodiment, pressing and holding the "emergency stop" button 170 for, for example, three seconds initiates the emergency stop process, which will be described later. In other words, by clearly informing the user that it is the "emergency stop" button and that it has been pressed and held for three seconds or more, the emergency stop process can be performed quickly.

[0012] On the right side of the operation panel 40, there are provided drying temperature setting buttons (low, medium, high) 180 for drying. Below that, there is provided a charge / remaining time display section 190. In this embodiment, the flicker lamp 140 and the charge / remaining time display section 190 are configured to display an emergency stop state.

[0013] Fig. 3 is a schematic diagram showing the internal configuration of the laundry machine 10. Fig. 4 is a cross-sectional side view of the laundry machine 10, showing an outline of the drum rotation mechanism. As shown in Figs. 3 and 4, a water supply pipe 205 for water, hot water, or mixed lukewarm water used for washing and rinsing the laundry is connected to the upper side of the outer body 200 constituting the washing tub, and a drain pipe 210 for discharging the washing water is connected to the lower side. The outer body 200 stores water, hot water, or mixed lukewarm water supplied via the water supply valve 205a or 205b and the water supply pipe 205. The stored water, hot water, or mixed lukewarm water is discharged to the outside from the drain pipe 210 via the drain valve 210a. Detergent pumps A, B, and C are also connected to the water supply pipe 205, so that detergents according to the type can be supplied into the washing tub. The outer body 200 is provided with a water level sensor 215 for detecting the water level. The water level sensor 215 outputs the detection data to the control device 400 (see Fig. 5).

[0014] In addition, the outer shell 200 is connected to a hot air supply passage 225 that supplies hot air for drying to an in-port 225a provided between the drum 220 and the opening and closing door 20, and a hot air discharge passage 235 is connected to an exhaust hole 230 provided at the rear of the upper surface of the outer shell 200. The hot air supply passage 225 is provided with a heating unit 240 composed of a gas burner, an input temperature sensor 245, an overheating prevention device and a safety device (not shown), etc. On the other hand, the hot air discharge passage 235 is provided with a lint filter 250 that captures garbage such as threads, a fan 255, a check damper 260 to prevent backflow, an overheating prevention device (not shown), etc. In addition, an exhaust duct 265 is provided to connect the exhaust hole 230 provided at the rear of the upper surface of the outer shell 200 and the hot air discharge passage 235. Since the vibrations of the rotational movement of the built-in drum 220 are also transmitted to the outer body 200, the exhaust duct 265 has a structure (for example, a bellows-shaped cross section) that can handle the vibrations.

[0015] In the drying operation, when the fan 255 provided in the hot air discharge path 235 is rotated, the air (hot air) heated by the heating unit 240 is guided to the hot air supply path 225 and supplied to the inside of the outer body 200. This dries the laundry put into the drum 220 rotating inside the outer body 200. At this time, the air containing moisture is guided from the exhaust hole 230 of the outer body 200 through the exhaust duct 265 to the hot air discharge path 235 and discharged to the outside.

[0016] An outlet temperature sensor 270 is disposed in the hot air exhaust path 235. The outlet temperature sensor 270 measures the temperature of the air guided from the outer shell 200 through the exhaust duct 265 to the hot air exhaust path 235. The outlet temperature sensor 270 then outputs the measurement data to the control device 400.

[0017] As shown in Fig. 4, the drum 220 is disposed with a predetermined gap from the outer body 200 so that its opening coincides with the input port of the outer body 200. The drum 220 has a rotating shaft 300 extending rearward, which is supported by the outer body 200. A rotation drive unit 305 including a drive motor 280 and the like is connected to the rear end of the rotating shaft 300. The rotation drive unit 305 transmits the rotation of the drive motor 280 to the rotating shaft 300 via a pulley and a belt, thereby rotating the drum 220. The drive motor 280 rotates the drum 220 at a rotation speed adjusted by an inverter or a reducer in each washing and drying process.

[0018] Additionally, the outer body 200 is provided with an air duct 285 for venting air from inside the drum and detecting overflow of the water supply. Also provided is a balance sensor 290 for detecting the balance of the drum 220 during spin-drying. Balance detection by the balance sensor 290 is performed by detecting that the center position of the outer body 200 has moved a certain distance. Also provided below the outer body 200 is a wash temperature sensor 295 for determining the drying state of the laundry during drying. Note that the internal structure of the drum 220 is not directly related to this embodiment, so a description thereof will be omitted.

[0019] Next, an emergency stop process by the emergency stop program of the laundry machine according to the embodiment will be described. Fig. 5 is a block diagram showing the configuration of the control device 400 which executes the emergency stop control of the laundry machine according to the embodiment. Fig. 6 and Fig. 7 are flow charts showing the operation procedure of the emergency stop control by the emergency stop program of the control device 400. A program 420 which executes the emergency stop control is incorporated in a memory (RAM or ROM) 410 built into the control device 400. The control device 400 also has a built-in timer 425 which measures (counts down or counts up) the operation time, etc.

[0020] First, a user who enters a coin laundry store moves to an available laundry machine 10 that he or she wishes to use and first presses the "drum wash" button 160. The control device 400 then washes the drum 220 for, for example, 30 seconds. If washing the drum 220 is not desired, this operation may be omitted. Next, the user presses the "voice navigation" button 150 to set the laundry machine 10 to output announcements (such as the end of an operation) in audible voice output. This operation may also be omitted as appropriate.

[0021] When the washing of drum 220 for the set time is completed, the user opens door 20 and inserts laundry into drum 220 through the input opening. Then, the user closes door 20 and latches door 20 with handle 25. Next, the user selects the desired course button from among wash / dry button 100 or 110, wash button 120, and dry button 130 (these are non-contact buttons, so the user only needs to hold their hand over the button). The selected course is notified to control device 400 via the operation input unit.

[0022] The control device 400 outputs a fee / time display 430, which is the usage fee according to the selected course, and displays it on the fee / remaining time display unit 190. For example, when the wash / dry button 100 is selected, a usage fee of 1200 yen is displayed. The user inserts the usage fee (e.g., 1200 yen) displayed on the display unit 190 into the fee insertion slot 35. When the control device 400 receives the fee payment from the fee input unit 35a, it activates the door lock 25a, and locks the handle 25 so that the opening and closing door 20 cannot be opened.

[0023] The control device 400 further closes the drain valve 210a and opens the water supply valve 205a and / or 205b to inject cold water, hot water, or mixed lukewarm water into the washing tub (composed of the outer body 200 and the drum 220). When the control device 400 receives information from the water level sensor 215 that a predetermined amount of cold water, hot water, or mixed lukewarm water has accumulated in the washing tub, it closes the water supply valve 205a and / or 205b and drives the drive motor 280. The drive motor 280 is driven to rotate to rotate the rotary shaft 300, which rotates the drum 220 and starts the washing process. When the laundry device 10 starts operating, the control device 400 outputs the flicker lamp display 440 and displays the flicker lamp 140 in green, for example, to notify the user that the device is operating.

[0024] After the laundry machine 10 is operated, if the user notices that the laundry has been put into the drum 220 with the mobile device still in the pocket, and wants to stop the laundry machine 10 and remove the mobile device, the user presses and holds the "emergency stop" button 170 for 3 seconds or more. Then, the signal of the "emergency stop" button 170 being pressed and held is transmitted to the control device 400 as an interrupt signal 405, and is received by the control device 400 (S100 in FIG. 6). Note that if the "emergency stop" button 170 is pressed and held for 3 seconds or more during an error stop, the laundry machine 10 is also in an emergency stop state. The "emergency stop" button 170 is effective not only during the washing process, but also during the drying process. This allows the user to immediately stop the laundry machine 10 by simply pressing and holding the "emergency stop" button 170, which is clearly indicated on the front of the laundry machine 10, in the event of an emergency stop. Note that in the event of an emergency stop, no notification is made by a hello call.

[0025] The emergency stop control program 420 of the control device 400 starts the emergency stop operation upon receiving the interrupt signal 405 from the “emergency stop” button 170 . The emergency stop control program 420 first stops the drive motor 280, stops the rotation of the drum 220 to temporarily halt the operation, and opens the drain valve 210a (S110 in FIG. 6). At this time, no air volume error or overheat error is generated. When the drum 220 has completely stopped (S120 in FIG. 6), the door lock 25a of the opening and closing door 20 is released, allowing the opening and closing door 20 to be opened (S130 in FIG. 6). This makes it possible to immediately rescue a child if he or she is hiding inside the washing machine.

[0026] Next, the emergency stop control program 420 drains the water (or hot water or lukewarm water) in the washing tub through the drain valve 210a until the water level reaches a safe level. In step S110, the door lock 25a is immediately released regardless of the water level, but the door dock 25a may be released only when the water level has dropped to a safe water level (S120, S130). The setting may be configured to be freely switched.

[0027] Next, the emergency stop control program 420 sounds an error sound from a speaker (not shown) and outputs a flicker lamp display 440 to make the bow-shaped flicker lamp 140 flash red (for example, at 100% brightness). These operations notify the user that an emergency stop has occurred. Furthermore, for example, the countdown by the timer 425 built into the control device 400 is stopped. Furthermore, the emergency stop control program 420 prohibits the insertion of coins through the coin slot 35. Also, the program outputs the course lamp display 450 and causes the lamp of the course that was in operation (for example, the wash / dry course 100) to flash.

[0028] Next, the emergency stop control program 420 controls the display of the charge / remaining time display unit 190. Fig. 8 shows an example of the display on the display unit 190. First, to clearly indicate an emergency stop, "StoP" and the remaining time (for example, 55 minutes 18 seconds) are displayed alternately, as shown in Fig. 8(a). The user then opens the unlocked door 20 (Yes in S140 in FIG. 6) and performs an emergency stop procedure (S150 in FIG. 7). For example, the user may rescue a child from the drum 220, remove a mobile device from the laundry in the drum 220, or put laundry that was left behind back into the drum 220. When the user opens the door 20, the charge / remaining time display 190 alternately displays "door" and the remaining time (for example, 55 minutes and 18 seconds) as shown in FIG. 8(b). These displays notify the user of the status of the laundry equipment.

[0029] Next, if it is within 10 minutes after the start and end of the emergency stop operation (No in S160 in FIG. 7), the emergency stop control program 420 detects pressing of the course button in use (e.g., the course button 100 blinks when in use) (Yes in S170 in FIG. 7), and restarts the laundry device 10 from the stopped process (e.g., the washing process) (S180 in FIG. 7). Note that here, the course button in use is used as the restart button, but a separate restart button may be provided. Restarting may be performed, for example, from the beginning of the washing process, or may be performed after resupplying water from the stopped state. Also, immediately after the emergency stop (e.g., for 10 seconds), restarting by the course button is disabled. This is to prevent unintended restart from occurring when the hand that has been pressed and held down on the "emergency stop" button 170 is released, due to a reaction of a non-contact course button (one of 100 to 130).

[0030] On the other hand, if the emergency stop operation takes a long time, or if the user opens the door 20 after an emergency stop but then does something else, the operation of the laundry appliance 10 will end (S190 in FIG. 7) 10 minutes after the drive is stopped (Yes in S160 in FIG. 7). In this case, the number of times the laundry appliance 10 has been operated is counted up by +1 and managed. When the normal state is restored, the user will have to start the operation over from the beginning. Note that if a power outage occurs during an emergency stop and is then restored, the emergency stop state will continue from where it left off. Also, if an error occurs, the operation will not end.

[0031] In step S140 in FIG. 6, if the opening and closing door 20 is not opened (No in S140 in FIG. 6), when a set time (for example, 1 minute) has elapsed (S200 in FIG. 6), operation is automatically restarted from the stopped process (S210 in FIG. 7). The set time starts to count when the door lock 25a is released. The automatic restart function after an emergency stop may be set by the user. For example, if the time until automatic restart in the event of an emergency stop is set to 0 to 10 minutes, automatic restart is not enabled when set to 0 minutes. The washing, rinsing, drying and cooling processes after the restart are normal laundry machine operations, so a description thereof will be omitted.

[0032] As is clear from the above description, according to the laundry machine having an emergency stop function and the emergency stop program for the laundry machine according to the embodiment, the "emergency stop" button 170 is provided on the front of the laundry machine 10 visible to the user, so that the machine can be stopped immediately when an emergency occurs. Even if the "emergency stop" button 170 is pressed and held down, if the door 20 is not opened, the machine will automatically restart from the stopped state after a set time (e.g., one minute) has elapsed. Therefore, the machine can be restarted even if there is tampering with the button while the machine is unattended. Also, if the unlocked door 20 is opened and the restart button is pressed within a set time (e.g., 10 minutes) after the emergency stop operation has started, the machine can be restarted from the stopped process. Also, if the restart button is not pressed and a set time (e.g., 10 minutes) has elapsed without the restart button being pressed, the operation can be terminated.

[0033] In the embodiment, the laundry machine with the emergency stop function has an emergency stop button 170 on the front of the laundry machine 10 for stopping the operation of the laundry machine 10 in an emergency, and the control device 400 receives an interrupt signal 405 generated by pressing and holding the emergency stop button 170. The control device 400 receives the interrupt signal 405, and stops the washing tub drive means 280 as an emergency stop process, and releases the door lock 25a of the door 20 on the front of the laundry machine 10. If the unlocked door 20 does not open and the first set time has elapsed, the operation is resumed from the stopped process. This allows the control device 400 to be operated by an interrupt signal generated by pressing the "emergency stop" button 170 on the front of the laundry machine 10 that is visible to the user, and the machine can be stopped immediately. Furthermore, even if the "emergency stop" button 170 is pressed and held, if the opening and closing door 20 is not opened, the device will automatically restart from the stopped state after a set time (for example, one minute) has elapsed, so that the device can be restarted even if tampering with the buttons occurs while the device is unattended.

[0034] In the embodiment, the laundry machine with the emergency stop function has an emergency stop button 170 on the front of the laundry machine 10 for stopping the operation of the laundry machine 10 in an emergency, and the control device 400 receives an interrupt signal 405 by pressing and holding the emergency stop button 170. The control device 400 receives the interrupt signal 405, and as an emergency stop process, stops the washing tub drive means 280, opens the drain valve 210a, and releases the door lock 25a of the opening door 20 on the front of the laundry machine 10 on condition that the water in the washing tub drops to a safe water level. If the unlocked opening door 20 does not open and the first set time has elapsed, the operation is resumed from the stopped process. This allows the control device 400 to be operated by an interrupt signal generated by pressing the "emergency stop" button 170 on the front of the laundry machine 10 that is visible to the user, and the machine can be immediately stopped. Furthermore, even if the "emergency stop" button 170 is pressed and held, if the opening and closing door 20 is not opened, the device will automatically restart from the stopped state after a set time (for example, one minute) has elapsed, so that the device can be restarted even if tampering with the buttons occurs while the device is unattended.

[0035] The control device 40 of the laundry machine having an emergency stop function of the embodiment is configured to resume from the stopped process when the unlocked door 20 is opened and the restart button (e.g., the course button 100 in use) is pressed within a second set time after the emergency stop operation. This allows the stopped process to be resumed when the unlocked door 20 is opened and the restart button (e.g., the course button 100 in use) is pressed within a set time (e.g., 10 minutes) after the emergency stop operation begins.

[0036] The control device 40 of the laundry machine having an emergency stop function of the embodiment is configured to open the unlocked door 29 and terminate the operation when the second set time has elapsed. This allows the operation to be terminated if the set time (e.g., 10 minutes) has elapsed without the restart button (e.g., the course button 100 in use) being pressed.

[0037] The emergency stop program of the laundry machine of the embodiment is a program executed by the control device 400 that controls the laundry machine 10 having an emergency stop function, and includes the steps of receiving an interrupt signal 405 by pressing and holding the emergency stop button 170 on the front of the laundry machine 10 (S100), stopping the driving means 280 of the washing tub and unlocking the door lock 25a of the door 20 on the front of the laundry machine 10 (S120), and restarting the operation from the stopped step if the unlocked door 20 does not open and the first set time has elapsed (Yes in S200). This allows the control device 400 to be operated by an interrupt signal by pressing the "emergency stop" button 170 on the front of the laundry machine 10 that is visible to the user, and the machine can be stopped immediately. Furthermore, even if the "emergency stop" button 170 is pressed and held, if the opening and closing door 20 is not opened, the device will automatically restart from the stopped state after a set time (for example, one minute) has elapsed, so that the device can be restarted even if tampering with the buttons occurs while the device is unattended.

[0038] The emergency stop program of the laundry machine of the embodiment is a program executed by the control device 400 that controls the laundry machine 10 having an emergency stop function, and includes the steps of receiving an interrupt signal 405 by pressing and holding the emergency stop button 170 on the front of the laundry machine 10 (S100), stopping the driving means 28 of the washing tub and unlocking the door lock 25a of the opening door 20 on the front of the laundry machine 10 on the condition that the water in the washing tub drops to a safe water level by opening the drain valve 210a (S120), and restarting the operation from the stopped step if the unlocked opening door 20 does not open and the first set time has elapsed (Yes in S200). This allows the control device 400 to be operated by an interrupt signal by pressing the "emergency stop" button 170 on the front of the laundry machine 10 that is visible to the user, and the machine can be stopped immediately. Furthermore, even if the "emergency stop" button 170 is pressed and held, if the opening and closing door 20 is not opened, the device will automatically restart from the stopped state after a set time (for example, one minute) has elapsed, so that the device can be restarted even if tampering with the buttons occurs while the device is unattended.

[0039] The emergency stop program of the laundry machine in the embodiment is a program further including a process (S180) of restarting the stopped process when the unlocked door 20 is opened and a restart button (e.g., the course button 100 in use) is pressed within a second set time after the emergency stop operation (S150, No in S160, Yes in S170). As a result, when the unlocked door 20 is opened and a restart button (e.g., the course button 100 in use) is pressed within a set time (e.g., 10 minutes) after the start of the emergency stop operation, the stopped process can be restarted.

[0040] The emergency stop program of the laundry machine in the embodiment is a program that has a process of opening the unlocked door 20 and terminating the operation if the second set time has elapsed (Yes in S160, S190). This allows the operation to be terminated if the set time (e.g., 10 minutes) has elapsed without the restart button (e.g., the course button 100 in use) being pressed.

[0041] The embodiments of the present invention are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
