Description

[Technical Field]

[0001] The present disclosure relates to washing machines and methods. [Background technology]

[0002] For example, Patent Document 1 discloses a washer-dryer having a control device that executes a tub drying process.

[0003] In the washing machine described in Patent Document 1, when the control device determines that the lid for closing the washing tub has been opened or closed, the control device automatically executes the tub drying process. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-49254 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in order to transition to the tub drying process after a normal washing operation, the tub needs to be empty. However, if the lid is accidentally closed while removing laundry from the washing tub after a washing operation, the user may unintentionally transition to the tub drying process when the tub is not empty. Therefore, the washing machine described in Patent Document 1 still has room for improvement in terms of transitioning to the post-process course even when the user does not intend to do so.

[0006] Therefore, an object of the present disclosure is to solve the above-mentioned problems and to provide a washing machine and method that can perform operations that are more in line with the user's intentions. [Means for solving the problem]

[0007] A washing machine according to one aspect of the present disclosure comprises a washing tub for storing laundry, an outer tub with the washing tub rotatably housed inside, a housing that elastically supports the outer tub, a motor for rotating the washing tub, a lid for opening and closing an opening in the housing for loading and unloading laundry, a reception unit that receives in advance courses to be executed by a user, and a control unit that executes the courses, the courses including a main operation having a spin-drying process and a post-process course that is executed after the main operation and involves driving the motor, and the control unit does not execute the post-process course after the main operation until it receives an instruction to start the post-process course.

[0008] A method according to one aspect of the present disclosure is a method for causing a washing machine to execute a course input in advance by a user, the method including the steps of: a control unit executing the course executing a wash run having a spin-drying process; a control unit sequentially determining whether a lid for opening and closing the housing opening was in an open state or a closed state after the wash run; and, when the control unit determines that it has received a start instruction instructing the start of a post-process course involving rotation of a motor that drives a washing tub that holds laundry, executing the post-process course. [Effects of the Invention]

[0009] According to the present disclosure, it is possible to provide a washing machine and a method that can perform operations that are more in line with the user's intentions. [Brief explanation of the drawings]

[0011] (Findings that formed the basis of this disclosure) At the time when the inventors arrived at the present disclosure, there were washing machines that performed a post-processing course after a wash cycle to clean the inside of the washing machine and prevent mold growth. The post-processing course was designed to start automatically after the wash cycle was completed, laundry was removed from the washing tub, and the closed state of the lid was detected.

[0012] The inventors discovered a problem in that when the post-processing course is automatically started, the operation may start without the user's intention. Specifically, if the user accidentally closes the lid while removing laundry, it is undesirable for the post-processing course to automatically start. Also, if a foreign object accidentally falls into the washing tub, it is undesirable for the post-processing course to automatically start before the user has removed the foreign object.

[0013] In order to solve the above problem, the inventors have come up with the subject matter of the present disclosure. The present disclosure provides a washing machine and a washer-dryer that start a post-processing course only when the user inputs a start command after detecting whether the lid is opened or closed after the washing operation has finished.

[0014] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of well-known matters or redundant description of substantially the same configuration may be omitted. This is to avoid unnecessary redundancy in the following description and to facilitate understanding by those skilled in the art.

[0015] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0016] (Embodiment) A washing machine according to an embodiment of the present disclosure will be described.

[0017] [Overall configuration] Fig. 1 is a perspective view of the appearance of a washer-dryer in accordance with a first embodiment of the present disclosure. Fig. 2 is a vertical cross-sectional view of the washer-dryer 1. Fig. 3 is a block circuit diagram of the washer-dryer 1.

[0018] 1 to 3 , the washer-dryer 1 includes a housing 6, an outer tub 8, a washing tub 2, a motor 14, a heat pump unit 10, an air passage 23, a water supply valve 30, a drain valve 31, a functional particle supply means 3, a control unit 25, and an operation display unit 5.

[0019] <Case> 1, the housing 6 is a member that forms the exterior of the washer / dryer 1. The front surface of the housing 6 is provided with an opening 6a and an openable / closable lid 4 that covers the opening 6a.

[0020] The washer / dryer 1 further includes a lid open / close detection means 21 for detecting whether the lid 4 is open or closed. The lid open / close detection means 21 is provided around the opening 6a. The lid open / close detection means 21 may be a sensor that detects whether the lid 4 has approached or moved away from the opening 6a. The lid open / close detection means 21 may be, for example, a Hall IC element that detects the magnetic flux of a magnet provided in the lid 4, or another method may be used. The control unit 25 detects whether the lid 4 is open or closed when the magnetic flux detected by the lid open / close detection means 21 is above or below a certain threshold.

[0021] <Outer tank> As shown in FIG. 2, outer tub 8 is a roughly cylindrical member provided inside housing 6 and functions to store wash water. Outer tub 8 has an opening facing opening 6a of housing 6, which is connected to opening 6a of housing 6 in a sealed manner. Outer tub 8 is further provided with multiple openings 33, 34 and drain outlet 35. Openings 33, 34 are openings connected to air flow path 23, and drain outlet 35 drains water from outer tub 8 to the outside. Openings 33, 34 are provided in the upper part of outer tub 8, and drain outlet 35 is provided in the lower part of outer tub 8.

[0022] <Washing tub> The washing tub 2 is a roughly cylindrical member that is rotatably provided inside the outer tub 8 and that contains laundry such as clothes. A large number of through-holes 2a are formed in the washing tub 2. The through-holes 2a connect the washing tub 2 and the outer tub 8, allowing water and air to move between the washing tub 2 and the outer tub 8. The washing tub 2 also has an opening at a position facing the opening 6a of the housing 6.

[0023] <Motor> Motor 14 is a member that drives and rotates washing tub 2. Motor 14 drives and rotates washing tub 2 in forward and reverse directions. In this embodiment, motor 14 is a belt-type motor that acts on washing tub 2 via a pulley. Therefore, the rotation speed of motor 14 and the rotation speed of washing tub 2 may differ. On the other hand, motor 14 may be another type of motor, such as a direct drive motor.

[0024] <Heat pump unit> The heat pump unit 10 is disposed in the air flow path 23 and is a device for dehumidifying and heating the air flowing through the air flow path 23. The heat pump unit 10 is provided in the upper part of the housing 6. Alternatively, the heat pump unit 10 may be provided in the lower part of the housing 6.

[0025] The heat pump unit 10 includes, for example, a compressor, a throttling mechanism, a heating heat exchanger, a dehumidifying heat exchanger, and refrigerant piping.

[0026] <Air flow path> The airflow path 23 is provided inside the housing 6 and is a flow path that circulates air between the outer tub 8 and the heat pump unit 10. The airflow path 23 is a generally sealed system. One end of the airflow path 23 is connected to an opening 33 in the outer tub 8, and the other end of the airflow path 23 is connected to an opening 34 in the outer tub 8. In this embodiment, the opening 34 is provided on the back surface of the outer tub 8. The opening 34 may also be provided on the front surface of the outer tub 8 or on the circumferential surface of the outer tub 8. Similarly, the opening 33 may also be provided on the front surface of the outer tub 8, the back surface of the outer tub 8, or the lower part of the outer tub 8.

[0027] <Blower fan> The blower fan 11 is a mechanism such as a fan that generates an air flow in the air flow path 23. The blower fan 11 generates an air flow that circulates through the air flow path 23 (see arrow F). The blower fan 11 is rotationally driven by a blower fan motor 13.

[0028] <Water supply valve> The water supply valve 30 is a valve for supplying water to the outer tub 8. The water supply valve 30 is provided on the upper part of the housing 6.

[0029] <Drain valve> The drain valve 31 is a valve for selectively draining water stored in the outer tub 8 through a drain port 35 of the outer tub 8. The drain valve 31 is provided at the bottom of the housing 6.

[0030] <Functional particle supply means> The functional particle supplying means 3 is a device that supplies functional particles. The functional particle supplying means 3 is provided downstream of the blower fan 11 in the air blowing path 23. The functional particle supplying means 3 delivers the functional particles to the outer tub 8 and the washing tub 2 through the air blowing path 23.

[0031] In this specification, functional particles are particles that can sterilize or suppress bacteria, viruses, pollen, etc. Functional particles may include substances such as charged atomized water particles, ions, ozone, etc. The functional particles can sterilize mold spores attached to the wall surface of the outer tub 8. Specifically, the functional particles can sterilize mold spores attached to the wall surface of the outer tub 8 by being delivered to the wall surface of the outer tub 8 by the air flow. Furthermore, the functional particles can sterilize mold spores attached to the wall surface of the washing tub 2 and clothes placed in the washing tub 2.

[0032] In this embodiment, an electrostatic atomizer is used as the functional particle supplying means 3 to generate charged atomized water particles as functional particles. Charged atomized water particles have a long life among functional particles. Therefore, a larger number of functional particles that maintain their sterilizing function (i.e., are not inactivated) can be delivered to the wall surface of the outer tub 8. This improves the sterilization performance of the washer / dryer 1 against mold spores.

[0033] Alternatively, ions may be used as the functional particles, and an ion generating device may be used as the functional particle supplying means 3. Alternatively, ozone may be used as the functional particles, and an ozone generating device may be used as the functional particle supplying means 3.

[0034] <Control unit> Control unit 25 is a component that controls the operation of washer / dryer 1. Control unit 25 may include, for example, a memory (not shown) that stores a control program and a processing circuit (not shown) that corresponds to a processor such as a CPU, and function as these elements by the processor executing the program.

[0035] As shown in FIG. 3, the control unit 25 controls components of the washer-dryer 1, such as the motor 14, the water supply valve 30, the drain valve 31, the heat pump unit 10, the functional particle supply means 3, and the blower fan motor 13, based on information input through the operation display unit 5.

[0036] <Operation display section> Operation display unit 5 is a mechanism that can be operated by the user of washer / dryer 1. Operation display unit 5 is arranged on the top of housing 6, and receives input from an input setting means (not shown) of operation display unit 5, and displays the input information to inform the user.

[0037] 4 is a schematic diagram of the operation and display unit 5. As shown in FIG. 4, the operation and display unit 5 has a touch panel 15, a start button 16, and a buzzer 20.

[0038] The touch panel 15 is a device that realizes an instruction input function and a display function. The touch panel 15 is, for example, a liquid crystal touch panel. The touch panel 15 has a portion that functions as a display unit 17 and an operation unit 18. The display unit 17 and the operation unit 18 shown in FIG. 4 are only examples, and are not limited to these. The display unit 17 having the instruction input function and the operation unit 18 having the display function may be configured separately. For example, the display unit 17 may be configured as a liquid crystal panel, and the operation unit 18 may be configured as a button type.

[0039] Operation unit 18 is a section where a user inputs instructions to washer-dryer 1. A user inputs a course to be executed by washer-dryer 1 via operation unit 18. In the present embodiment, operation unit 18 is temporarily displayed on touch panel 15.

[0040] The display unit 17 is a part that displays information about the course or instructions to the user, and can freely display any characters or numbers.

[0041] The start button 16 is a button that starts the input course. When the start button 16 is pressed before the start of the course operation, the course starts. In other words, the start button 16 can be used to input an instruction to start the course. The start button 16 may further have a function to temporarily suspend the input course. When the start button 16 is pressed while the course is being operated, the course is temporarily suspended. The suspending function allows the driver to temporarily suspend operation if the course is started unintentionally, or if the driver realizes after starting that the operation is not as intended. In this embodiment, the start button 16 is provided away from the touch panel 15. The start button 16 is provided near one lateral end of the housing 6. On the other hand, the start button 16 may be temporarily displayed on the display unit 17.

[0042] The washer-dryer 1 further includes a buzzer 20. The control unit 25 controls the buzzer 20 to emit a sound depending on the state of the washer-dryer 1.

[0043] [Operation] With the above configuration, an example of the operation of the washer-dryer 1 that executes the washing operation and post-process course will be described with reference to Figs. 5 to 7C. Fig. 5 is a process diagram of the operation including the washing operation and tub cleaning course executed by the washer-dryer 1. Figs. 6A and 6B are flowcharts of the operation including the washing operation and tub cleaning course executed by the washer-dryer 1. Figs. 7A to 7C are schematic diagrams of the operation display unit 5 in the acceptance process described below.

[0044] As shown in Fig. 5, in this embodiment, an example will be described in which the post-process course is a tub cleaning course. That is, the user inputs a laundry processing course including a washing operation and a tub cleaning course. The tub cleaning course is a maintenance process of the washer-dryer 1 that sterilizes the inside of the washer-dryer 1. Specifically, in the tub cleaning course, the functional particle supplying means 3 operates to deliver functional particles to the washing tub 2 and outer tub 8. Through this operation, the washing tub 2 and outer tub 8 are sterilized, and the growth of mold can be suppressed.

[0045] When the laundry treatment course is executed, the control unit 25 first executes a washing operation. When the washing operation (S11 to S14) is completed, the control unit 25 proceeds to a reception step (S16 to S31) of receiving a command to press the start button 16 to start a tub clean course. When the start button 16 is pressed in the reception step, the control unit 25 executes a tub clean course (S41 to S42, S43 to S44).

[0046] As shown in FIG. 6A, first, the control unit 25 acquires the laundry treatment course input by the user through the operation display unit 5 (S10).

[0047] Next, the control unit 25 starts the washing operation (S11). Specifically, the control unit 25 starts the washing operation when the user puts laundry in the washing tub 2, closes the lid 4, and then presses the start button 16.

[0048] The washing operation includes a washing process, a rinsing process, and a spin-drying process. Control unit 25 executes the washing process, rinsing process, and spin-drying process in that order. In the washing process, water is supplied, and detergent is supplied to washing tub 2 along with the water, and washing tub 2 is rotated by motor 14 to wash the laundry. In the rinsing process, water is supplied, and washing tub 2 is rotated to rinse the laundry. In the spin-drying process, after the wash water is drained outside housing 6, washing tub 2 is rotated at high speed to spin-dry the laundry.

[0049] The washing operation only needs to include at least a spin-drying process. By performing the spin-drying process, it is possible to prevent the operation from ending with water still remaining in washing tub 2.

[0050] Next, when the washing operation is completed, the control unit 25 causes the buzzer 20 to sound (S12). The buzzer 20 may sound once or multiple times, for example, six times.

[0051] Next, the control unit 25 determines whether the input laundry treatment courses include a tub clean course (S13).

[0052] If the tub clean course is included (Yes in S13), control unit 25 causes display unit 17 to display an end display (S14). FIG. 7A shows an example of an end display displayed after the end of a washing operation when the tub clean course is set. In this embodiment, display unit 17 displays, on the same screen, as the end display, a message indicating that the washing operation has ended and that the tub clean course will start when start button 16 is pressed. By displaying that the washing operation has ended, the user can recognize that the washing operation has ended normally, preventing the user from mistakenly believing that an abnormality has occurred in the washing operation. This also encourages the user to remove the laundry. By displaying on the same screen that the washing operation has ended and that the tub clean course will start, the user can be reliably informed of the current situation and be guided to the next action. Furthermore, by displaying a message indicating that the tub clean course will start when start button 16 is pressed before opening or closing lid 4, i.e., when the user approaches washer-dryer 1 to remove the clothes, the user can easily see the message indicating that the tub clean course will start when start button 16 is pressed.

[0053] Note that display unit 17 does not have to display, on the same screen, the message that the washing operation has ended and the message that the tub clean course will start when start button 16 is pressed. For example, instead of displaying them on the same screen, the message that the washing operation has ended and the message that the tub clean course will start when start button 16 is pressed may be displayed in order or alternately.

[0054] The message indicating that the washing operation has finished may be emphasized more than the message indicating that the tub clean course is being executed. In this embodiment, the message indicating that the washing operation has finished is emphasized by changing the font size and starting a new line. Display unit 17 may also display instructions to remove the laundry or to close lid 4.

[0055] If the tub clean course is not included (No in S13), the control unit 25 turns off the power of the washer / dryer 1 (S15) and ends the control.

[0056] Next, the control unit 25 determines whether a predetermined time has elapsed since the end of the washing operation (S11) (S16). In this embodiment, the control unit 25 determines whether eight hours have elapsed since the end display was displayed.

[0057] If eight hours have passed since the end of the washing operation (Yes in S16), the control unit 25 turns off the power of the washer / dryer 1 (S17) and ends the control.

[0058] If eight hours have not passed since the end of the washing operation (No in S16), the control unit 25 determines whether the lid 4 is open (S18). Specifically, the lid open / close detection means 21 detects whether the lid 4 is open, and the control unit 25 acquires the detection result. Through this operation, the control unit 25 can determine whether the user has opened the lid 4 to remove laundry.

[0059] If it is determined that the lid 4 is not in the open state (No in S18), that is, if it is detected that the lid 4 is in the closed state, the control unit 25 returns to step 16 after a certain interval.

[0060] If it is determined that the lid 4 is in the open state (Yes in S18), that is, if it is detected that the lid 4 is in the open state, the control unit 25 determines whether the lid 4 is in the closed state (S19). Specifically, the lid open / close detection means 21 detects whether the lid 4 is in the closed state, and the control unit 25 acquires the detection result. Through this operation, the control unit 25 can determine whether the user has finished removing the laundry and closed the lid 4. By detecting the open state and the closed state of the lid 4 in sequence, it can be determined that the clothes have been removed from the washing tub 2.

[0061] If it is determined that the lid 4 is not in the closed state (No in S19), that is, if it is detected that the lid 4 is in the open state, the control unit 25 returns to step 16 after a certain interval.

[0062] If it is determined that the lid 4 is closed (Yes in S19), i.e., if it is detected that the lid 4 is closed, the control unit 25 causes the display unit 17 to display a first display (S20). FIG. 7B shows an example of the first display that is displayed when the opening or closing of the lid 4 is detected. In this embodiment, the first display stops displaying the information indicating that the washing operation has ended and displays a message prompting the user to press the start button 16. The first display in this embodiment includes a direct instruction to press the start button 16, such as the text "Please press start." Narrowing the information displayed can prompt the user to start a post-process course. In this embodiment, the first display also displays a message indicating that the tub clean course will start.

[0063] Next, control unit 25 causes buzzer 20 to sound (S21). Buzzer 20 may sound once or multiple times, for example, twice. By sounding buzzer 20, a user who has moved away from the washer-dryer 1 is reminded of the washer-dryer 1 and is made aware that they have forgotten to operate it. After sounding buzzer 20 twice, control unit 25 stops buzzer 20. This operation prevents the buzzer 20 from sounding for a long time, which could lead to the user mistakenly thinking that an abnormality has occurred in the washer-dryer 1.

[0064] Step 21 may be performed simultaneously with step 20.

[0065] Next, as shown in FIG. 6B, the control unit 25 determines whether or not the start button 16 has been pressed (S22).

[0066] When the start button 16 is pressed (Yes in S22), the control unit 25 executes the tub clean course (S41). Thereafter, the control unit 25 turns off the power of the washer / dryer 1 (S42) and ends the control.

[0067] If the start button 16 is pressed between step 20 and step 21, the tank clean course may be started without the buzzer 20 issuing an alert.

[0068] If the start button 16 has not been pressed (No in S22), the control unit 25 determines whether a predetermined time, for example, two minutes, has passed since the previous buzzer alert (S25). The previous buzzer alert refers to the previous buzzer alert, specifically, the buzzer alert in step 20 if this is the first step 25 since the start of operation, and the buzzer alert in the previous step 26 if this is the second or subsequent step 25.

[0069] If the control unit 25 determines that two minutes have passed since the previous buzzer alert (Yes in S25), it causes the buzzer 20 to alert (S26). The buzzer 20 may sound once or multiple times, for example, four times. The buzzer 20 may sound at shorter intervals compared to step 21. If the control unit 25 determines that two minutes have not passed since the previous buzzer alert (No in S25), it returns to step 22.

[0070] Next, the control unit 25 determines whether a predetermined time has elapsed since it was detected that the lid 4 was closed (S27). In this embodiment, the control unit 25 determines whether 30 minutes have elapsed since step 19.

[0071] If 30 minutes have not passed since the end of the washing operation (No in S27), the process returns to step 22. By performing this operation, before 30 minutes have passed since the end of the washing operation, the control unit 25 can sound the buzzer 20 at two-minute intervals to prompt the user who has left the washer-dryer 1 to press the start button 16.

[0072] The sounding pattern of the buzzer 20 may be changed from the second time onwards in step 26. For example, the length of time the buzzer 20 sounds, the number of times it sounds, the interval between sounds, etc. may be changed. For example, from the second time onwards in step 26, the buzzer 20 may sound continuously for 10 seconds.

[0073] If 30 minutes have passed since the end of the washing operation (Yes in S27), control unit 25 stops buzzer 20 and causes display unit 17 to display the second display (S28). FIG. 7C shows an example of the second display that is displayed a predetermined time after the opening or closing of lid 4 is detected. As shown in FIG. 7C, the second display is a display that notifies the user of the status of washer-dryer 1. Specifically, the second display displays, on the same screen, that the washing operation has ended, that a tub clean course will be executed, and that a user is prompted to press start button 16. In this embodiment, the second display displays that the washing operation has ended and that the tub clean course will start when start button 16 is pressed.

[0074] This operation indicates to the user that the washer-dryer 1 has finished the washing operation and is waiting for the user to press the start button. Therefore, if the user is not aware that the tub clean course will be run after the reception process, the user can be made to clearly understand that the post-process will be run. This prevents the user from turning off the power of the washing machine during the reception process.

[0075] Note that display unit 17 does not have to display, on the same screen, the message that the washing operation has ended, the message that the tub clean course will be executed, and the message prompting the user to press start button 16. For example, instead of displaying these on the same screen, the message that the washing operation has ended and the message that the tub clean course will start when start button 16 is pressed may be displayed in sequence or alternately.

[0076] In this embodiment, the display mode of the second display is the same as the display mode of the end display, but may be different.

[0077] The second display may be a display mode in which the screen is turned off by reducing the brightness of touch panel 15. Such an operation can reduce power consumption.

[0078] Next, the control unit 25 determines whether a predetermined time has passed since the end of the washing operation (S11) (S29). In this embodiment, the control unit 25 determines whether eight hours have passed since the end display was displayed.

[0079] If eight hours have passed since the end of the washing operation (Yes in S29), the control unit 25 turns off the power of the washer / dryer 1 (S30) and ends the control.

[0080] If eight hours have not passed since the end of the washing operation (No in S29), the control unit 25 determines whether the start button 16 has been pressed (S31).

[0081] If start button 16 is pressed (Yes in S31), control unit 25 executes the tub clean course (S43). Thereafter, control unit 25 turns off the power of washer / dryer 1 (S44) and ends the control.

[0082] If the start button 16 is not pressed (No in S31), the control unit 25 returns to step 29. Until eight hours have passed (Yes in S29), the display unit 17 continues to display the display mode displayed in the second display.

[0083] The above-described operation can prevent the tank clean course from being started without a positive instruction from the user, that is, without the user's intention.

[0084] The tub clean course will now be described in more detail with reference to Fig. 5, Fig. 8, and Fig. 9. Fig. 8 is an operational diagram of the washer-dryer 1 executing the tub clean course. Fig. 9 is a vertical cross-sectional view of the washer-dryer 1 showing the air flow caused by the rotation of the washing tub 2.

[0085] 5, the tub cleaning course includes a drying process and a sterilization process. The control unit 25 executes the drying process and the sterilization process in this order. The drying process is executed to remove residual water in the outer tub 8 after the spin-drying process. The sterilization process is executed to deliver functional particles to the wall surface of the outer tub 8.

[0086] First, the control unit 25 executes the drying process. As shown in Fig. 8, in the drying process, the control unit 25 activates the motor 14 and the blower fan 11. On the other hand, the control unit 25 does not activate the functional particle supplying means 3.

[0087] In the drying process, washing tub 2 is rotated by operating motor 14. When washing tub 2 rotates, an air flow occurs in air blowing path 23. Here, with reference to Figs. 2 and 9, the air flow caused by the rotation of washing tub 2 will be described in comparison with the air flow caused by blower fan 11.

[0088] As shown in FIG. 2, when blower fan 11 rotates while washing tub 2 is stationary, air flows into washing tub 2 through opening 34, passes over the top of washing tub 2, and flows out through opening 33 (arrow F). Therefore, air is less likely to flow throughout region R1 between washing tub 2 and outer tub 8. On the other hand, as shown in FIG. 9, when washing tub 2 rotates, centrifugal force acts on the air inside washing tub 2, causing the air to flow through through-holes 2a toward outer tub 8, which is located outside washing tub 2 (arrow C). Because the air flows out due to centrifugal force, air also flows into region R1, which is away from opening 34. In other words, the rotation of washing tub 2 makes it easier for air to flow throughout region R1, making it more likely for the air to hit the wall surfaces that make up region R1 (e.g., the wall surfaces of outer tub 8). Therefore, the rotation of washing tub 2 efficiently dries the wall surfaces that make up region R1.

[0089] When air flows out of washing tub 2, negative pressure is created in washing tub 2, and air flows into washing tub 2 through air blowing path 23. In this way, the rotation of washing tub 2 generates a flow of air circulating through air blowing path 23.

[0090] Furthermore, by operating the blower fan 11, the air flow in the air flow path 23 can be further promoted.

[0091] Returning to Figures 5 and 8, the drying process more specifically includes a room-temperature air blowing process and a heated air blowing process. The room-temperature air blowing process and the heated air blowing process differ in terms of the ON / OFF of the heat pump unit 10. In other words, in the drying process, the control unit 25 delays the start of operation of the heat pump unit 10 relative to the start of operation of the blower fan 11 and the motor 14. The room-temperature air blowing process corresponds to the start-up time of the heat pump unit 10. The heat pump unit 10 requires a start-up time before it is turned ON. During the start-up time, for example, the compressor of the heat pump unit 10 is rotated at a low speed or is only energized to raise the refrigerant temperature to a predetermined temperature or higher. This allows the heat pump unit 10 to perform as expected in the heated air blowing process.

[0092] In this embodiment, in the drying process, control unit 25 continuously operates blower fan 11 and motor 14. As will be described later (see FIG. 9), the rotation of motor 14, i.e., the rotation of washing tub 2, guides the air in washing tub 2 into outer tub 8. By operating continuously, air can be continuously delivered to outer tub 8. Therefore, compared to when motor 14 is driven intermittently, residual water in outer tub 8 can be removed in a short time.

[0093] Furthermore, by moving to the sterilization process immediately after the drying process, it is possible to prevent a drop in temperature and an increase in humidity, thereby maintaining a state in which residual water around the mold spores in the outer tub 8 has been removed.

[0094] By removing the residual water in the outer tank 8 and maintaining the state in which the residual water is removed, the amount of functional particles that collide with the residual water and are deactivated in the subsequent sterilization step can be reduced.

[0095] During the sterilization process, motor 14 and functional particle supply means 3 are operated, and therefore functional particles are contained in the air flow caused by the rotation of motor 14 (i.e., washing tub 2). Because the functional particles flow out together with the air due to centrifugal force, the functional particles also flow into region R1 away from opening 34 (see arrow C in FIG. 9). That is, the rotation of washing tub 2 makes it easier for the functional particles to flow throughout region R1, and they are more likely to hit the wall surfaces that make up region R1 (for example, the wall surfaces of outer tub 8). Therefore, the rotation of washing tub 2 can efficiently sterilize the wall surfaces that make up region R1.

[0096] In the sterilization step, control unit 25 stops blower fan 11. When blower fan 11 operates, the pressure difference created by the operation of blower fan 11 causes air that has flowed from air flow path 23 through opening 34 into outer tub 8 to preferentially pass through washing tub 2 and flow out from opening 33. The air is less likely to hit the wall surface of outer tub 8 at positions away from openings 33 and 34. Therefore, the functional particles are also less likely to hit the wall surface of outer tub 8.

[0097] In addition, the amount of air blown by blower fan 11 is greater than the amount of air blown by the rotation of washing tub 2. When blower fan 11 operates, the number of functional particles that are deactivated by colliding with the wall surface of blower path 23 increases. As a result, the number of functional particles that maintain the sterilization function decreases.

[0098] Therefore, by stopping the blower fan 11, it is possible to deliver more functional particles that maintain their sterilization function to the wall surface of the outer tank 8. In addition, by stopping the blower fan 11, it is possible to reduce the operating noise during the sterilization process.

[0099] In the sterilization process, the control unit 25 stops the heat pump unit 10. When the heat pump unit 10 operates, the air in the air supply path 23 is heated. The entropy of the functional particles increases as the air is heated. As a result, the functional particles are more likely to be deactivated before being delivered to the outer tank 8.

[0100] Therefore, by stopping the heat pump unit 10, it is possible to deliver more functional particles that maintain their sterilization function to the wall surface of the outer tub 8. In addition, by stopping the heat pump unit 10, it is possible to save energy consumed by the washer-dryer 1 in the tub clean course.

[0101] In this embodiment, the rotation direction of the washing tub 2 is unidirectional during the sterilization process. This operation prevents the motor 14 from reversing and thus prevents the motor 14 from decelerating. By preventing the motor 14 from decelerating, the air flow toward the outer tub 8 can be maintained, allowing more functional particles to be delivered to the wall surface of the outer tub 8. On the other hand, the rotation direction of the washing tub 2 may be reversed. This operation allows the functional particles to be delivered evenly to the entire region R1.

[0102] Furthermore, the rotation direction of the washing tub 2 in the sterilization process is the same as the rotation direction of the washing tub 2 in the drying process. Therefore, the motor 14 can be operated continuously without stopping to reverse the rotation between the drying process and the sterilization process. In this embodiment, the rotation direction of the washing tub is assumed to be clockwise, but it can also be counterclockwise as appropriate.

[0103] In the sterilization step, the rotation speed of the washing tub 2 is lower than the rotation speed in the spin-drying step (e.g., 1000 rpm). The rotation speed of the washing tub 2 is, for example, 35 rpm. By lowering the rotation speed of the washing tub 2, the load on the motor 14, noise, and running costs can be reduced.

[0104] [effect] The washer / dryer 1 according to the embodiment can achieve the following effects.

[0105] As described above, the washer-dryer 1 of this embodiment includes a washing tub 2 that stores laundry, an outer tub 8 that rotatably accommodates the washing tub 2, a housing 6 that elastically supports the outer tub 8, and a motor 14 that rotates the washing tub 2. The washer-dryer 1 further includes a lid 4 that opens and closes a housing opening (opening 6a) for loading and unloading laundry. The washer-dryer 1 includes an operation unit 18 (reception unit) that accepts in advance a course to be executed by a user, and a control unit 25 that executes the course. The courses include a washing operation (main operation) that includes a spin-drying process, and a post-process course that is executed after the washing operation and involves driving the motor. The control unit 25 does not execute the post-process course after the washing operation until it receives an instruction to start the post-process course.

[0106] This configuration can prevent a post-process course such as a tub clean course from starting unintentionally by the user. For example, if the user accidentally closes the lid 4 while removing laundry from the washing tub 2, the post-process course can be prevented from starting automatically.

[0107] The washer / dryer 1 of this embodiment further includes lid open / close detection means 21 that detects whether the lid 4 is open or closed. Control unit 25 executes a post-process course reception step between the washing operation and the post-process course. After lid open / close detection means 21 detects the open state and the closed state of the lid 4 in sequence during the reception step, control unit 25 receives an instruction to start the post-process course and then executes the post-process course.

[0108] This configuration can prevent the post-process course from starting unintentionally by the user. For example, if the lid 4 is accidentally closed while removing laundry from the washing tub 2, the post-process course will not automatically start. In addition, by detecting the "opening and closing of the lid" required when the user removes laundry and then receiving a start command to start the post-process course, the post-process course can be started after the inside of the washing tub 2 has reached a state where the effects of the post-process course can be properly applied.

[0109] Washing / drying machine 1 of the present embodiment further includes display unit 17 capable of displaying any characters and numbers. Control unit 25 causes display unit 17 to display, in the reception process, that the post-process course will be executed (for example, FIG. 7A).

[0110] This configuration allows the user to clearly recognize that the entire operation has not ended, but that a subsequent process will be performed after the reception process.

[0111] The washer / dryer 1 of the present embodiment displays, on the same screen (for example, FIG. 7A), a message that the washing operation has ended and a message that the subsequent process course will be executed.

[0112] This configuration allows the user to recognize that the washing operation has been performed as intended by the user, and also allows the user to clearly recognize that the post-process course will be performed after the reception process.

[0113] When the washer / dryer 1 of this embodiment detects the opening and closing of the lid 4 using the lid opening / closing detection means 21, it stops the display indicating that the washing operation has ended and displays a message prompting the user to start a subsequent process course (for example, Figure 7B).

[0114] With this configuration, the amount of information displayed on the display unit 17 can be reduced, so that the user can be strongly encouraged to give an instruction to start the post-process course.

[0115] In the washer-dryer 1 of this embodiment, after 30 minutes (a predetermined time) have elapsed since the display prompting the user to start the post-process course, the washer-dryer 1 displays, on the same screen, a message indicating that the washing operation has ended, a message indicating that the post-process course will be executed, and a message prompting the user to start the post-process course (for example, FIG. 7C).

[0116] With this configuration, a user who has forgotten the current state of the washer-dryer 1 after a predetermined time has passed can be reminded that the current state is the reception process and strongly urged to give an instruction to start the subsequent process.

[0117] The washer / dryer 1 of this embodiment further includes a buzzer 20 (audio output unit). If a command to start the post-process course is not received within two minutes (first predetermined time), controller 25 issues an alert using buzzer 20. If a command to start the post-process course is not received within 30 minutes (second predetermined time), controller 25 stops issuing an alert using buzzer 20 and displays, on the same screen, a message that the post-process course will be executed and a message urging the user to issue a command to start the post-process course (for example, FIG. 7C).

[0118] With this configuration, a user who has forgotten the current state of the washer-dryer 1 after a predetermined time has passed can be prevented from mistakenly recognizing the alarm from the buzzer 20 as an abnormality alarm for the washer-dryer 1, while being reminded that the current state is the reception process and strongly urged to give an instruction to start the subsequent process.

[0119] The washer / dryer 1 of this embodiment further includes a start button 16 for issuing an instruction to start the post-process course. The operation unit 18 and the start button 16 are arranged apart from each other.

[0120] This configuration can prevent the start of a post-process course when the user does not intend it to be started due to an erroneous operation of the operation unit 18. If a touch panel is provided as the operation unit 18, separating the operation unit 18 from the start button 16 can prevent the touch panel from malfunctioning due to wet laundry.

[0121] In the washer / dryer 1 of the present embodiment, if the post-process course is not executed for eight hours (third predetermined time) in the reception process, the control unit 25 turns off the power after eight hours have elapsed.

[0122] This configuration prevents the post-process course from automatically starting even when lid 4 is left open and not closed for a long period of time or when start button 16 is not pressed. Also, control unit 25 determines that the user does not intend to operate the post-process and turns off the power without performing the post-process. This reduces the power consumption of washer / dryer 1.

[0123] The washer / dryer 1 of the present embodiment further includes functional particle supplying means 3 for supplying functional particles into the outer tub 8. As a post-process course, the control unit 25 operates the motor 14 and the functional particle supplying means 3 to execute a tub clean course for sterilizing the washing tub 2 and the outer tub 8.

[0124] This configuration prevents the tub clean course from starting unintentionally by the user. As the washing tub 2 rotates, centrifugal force acts on the air and functional particles, causing them to flow to the outside of the washing tub 2. This makes it easier to deliver the functional particles to the wall surface of the outer tub 8, thereby sterilizing mold spores adhering to the wall surface of the outer tub 8. This improves the sterilization performance of mold spores in the outer tub 8 in the washer / dryer 1.

[0125] The washer / dryer 1 of this embodiment further includes a start button 16 (start instruction unit), and the control unit 25 receives a start instruction through the start button 16.

[0126] With this configuration, a user can stand in front of the main body of the washer / dryer 1, check the contents, and input a start command.

[0127] The method of this embodiment is a method of causing washer / dryer 1 (washing machine) to execute a course input in advance by a user. The method includes a step in which control unit 25, which executes the course, executes a wash operation including a spin-drying process. The method includes a step in which control unit 25, after the wash operation, determines whether lid 4, which opens and closes opening 6a (housing opening), was in the open state and then in the closed state. The method includes a step in which control unit 25 executes a post-process course when it determines that it has received a start instruction to instruct the start of a post-process course involving rotation of motor 14, which drives washing tub 2 that stores laundry.

[0128] By using this method, it is possible to prevent a post-process course such as a tank cleaning course from being started when the user does not intend it to be started.

[0129] In the method of the present embodiment, control unit 25 receives a start instruction via start button 16 (start instruction unit) provided in washer / dryer 1.

[0130] In this manner, the user can stand in front of the main body of the washer / dryer 1, check the contents, and input a start command.

[0131] In this embodiment, the washer-dryer 1 has been described, but the present invention is not limited to this. The washer-dryer may be any machine that can wash laundry. It may be a washing machine that has only the function of washing laundry. The washer-dryer may also be a clothes dryer that has only the function of drying clothes.

[0132] In this embodiment, an example in which the post-process course is a tub clean course will be described, but the present invention is not limited to this. The post-process course may be another course that is executed after the laundry has been removed from the washing tub 2 and involves rotation of the washing tub 2. For example, the post-process course may be a tub drying course or a tub cleaning course.

[0133] In the present embodiment, an example has been described in which the washer-dryer 1 has the airflow path 23 for circulating air, but the invention is not limited to this. The washer-dryer 1 may be any machine capable of drying laundry. The washer-dryer 1 may have an exhaust path for passing air in one direction. On the other hand, if the washer-dryer 1 has the airflow path 23 for circulating air, the generated functional particles can be circulated inside the washer-dryer 1. This allows the interior of the washer-dryer 1 to be efficiently disinfected.

[0134] In the present embodiment, an example in which the tank cleaning course includes a drying step and a sterilization step has been described, but the present invention is not limited to this. The tank cleaning course may include a sterilization step.

[0135] In the present embodiment, an example has been described in which a command to start the post-processing course is input by pressing start button 16 on washer-dryer 1, but this is not limiting. Control unit 25 may be capable of receiving a command to start the post-processing course from a specific user. As shown in FIG. 10 , control unit 25 can transmit and receive internet packets, i.e., communicate, with external smartphone 100 or service server 200 via communication unit 50. For example, a specific user may input a command to start the post-processing course to washer-dryer 1 via terminal operation / display unit 105 by operating an application stored in the user's smartphone 100. The start command is communicated to washer-dryer 1 via terminal communication unit 150 of smartphone 100. Furthermore, the application stored in the user's smartphone 100 may display at least one of an end display, a first display, a second display, or a third display via terminal operation / display unit 105. Other settings for the washing course may be input to washer-dryer 1 by operating the application.

[0136] Furthermore, an identifier of the user's smartphone 100 or application may be used to identify the user who inputs the start instruction, so that only a limited number of users can input the start instruction for the post-process course. This allows, for example, only an application stored in the parent's smartphone 100 to issue the start instruction for the post-process course, thereby preventing erroneous operation of the washer-dryer 1 by a child.

[0137] In the present embodiment, an example has been described in which the washer-dryer 1 has a memory that stores the control program for the tub clean course, but the present invention is not limited to this. As shown in Fig. 10, the washer-dryer 1 may download the control program stored in the service server 200 via the Internet.

[0138] In the present embodiment, the washer / dryer 1 has the buzzer 20 as the notification unit, but the notification unit is not limited to this. The notification unit may be any other means for transmitting information to the user.

[0139] In the present embodiment, an example has been described in which the operation unit 18 and the start button 16 are arranged separately, but the present invention is not limited to this. The start button 16 may be included in the operation unit 18.

[0140] In the present embodiment, the example in which the display unit 17 is a display that can freely display any characters and numbers has been described, but the present invention is not limited to this. The display unit 17 may be a device that displays defined numbers and characters, as in Variation 1 below.

[0141] (Variation 1) Fig. 11 to Fig. 12C are schematic diagrams of operation display unit 55 in Modification 1. Fig. 11 shows operation display unit 55 before the start of operation, and Figs. 12A to 12C show operation display unit 55 after the start of operation. Specifically, Fig. 12A shows the display mode in the end display, Fig. 12B and Fig. 12C together show the display mode in the first display, and Fig. 12B alone shows the display mode in the second display.

[0142] 12A to 12C, lit characters are hatched on display unit 67. In Modification 1, only the characters included in the hatched area are lit, but the area around the hatched characters may also be lit.

[0143] As shown in FIG. 11, the operation and display unit 55 in the first modification includes an operation unit 65, a start button 16, and a display unit 67.

[0144] The operation unit 65 is configured with a plurality of buttons. For example, the laundry treatment course to be executed can be selected by whether or not each button is pressed, or by the number of times the button is pressed.

[0145] Display unit 67 displays specified numbers and letters. In this embodiment, display unit 67 has a character section 67A that displays the selected course by lighting or blinking letters, and a number section 67B that displays the remaining time using a 7-segment display. Numbers may be displayed in character section 67A, and letters may also be displayed in number section 67B.

[0146] The operation of the display unit 67 will now be described.

[0147] Before the reception process, display unit 67 displays the end display that is displayed after the end of the washing operation when the tub clean course is set. In this modified example, in the end display (S14) by display unit 67, tub mold bacteria sterilization 67AA, which means the tub clean course, lights up in character portion 67A, and "0 minutes remaining," which is the remaining time of the washing operation, is displayed in number portion 67B. Alternatively, number portion 67B may display "0 minutes" or a blank. By lighting tub mold bacteria sterilization 67AA, the user is made aware that the tub clean course is set before opening or closing lid 4.

[0148] Control unit 25 displays information about the tub clean course on display unit 67 during the reception process (S16 to S31). This allows the user to recognize, on the limited display area, that the entire operation has not ended and that a post-process will be performed after the reception process. Control unit 25 changes the display on display unit 67 depending on the state of washer / dryer 1.

[0149] Here, the steps of the reception process that differ from the first embodiment will be mainly explained.

[0150] In this modification, after detecting that the lid 4 is open (S18), the control unit 25 causes the display unit 67 to display the third display before subsequently detecting that the lid 4 is closed (S19). FIG. 12B shows an example of the display mode of the third display. In FIG. 12B, in the third display, tank mold sterilization 67AA is lit in the character portion 67A, and "3 hours 00 minutes remaining," which is the remaining time for the tank clean course, is displayed and lit in the number portion 67B. In this modification, information about the tank clean course is displayed as an example of the display mode of the third display.

[0151] Next, when the control unit 25 detects that the lid 4 is open (S18) and then detects that the lid 4 is closed (S19), it changes the display mode of the information about the tank clean course. That is, the control unit 25 changes the display mode of the third display. This display corresponds to the first display (S20). As shown in FIGS. 12B and 12C, in the first display by the display unit 67, the remaining time for the tank clean course, "3 hours and 00 minutes remaining," is displayed and flashes in the numeric portion 67B. The flashing interval of the tank mold sterilization 67AA may be constant or may vary. All letters and numbers (including "remaining," "hours," and "minutes") displayed in the numeric portion 67B may flash. Control unit 25 may also emphasize tank mold sterilization 67AA in character portion 67A and "3 hours 00 minutes remaining" in number portion 67B in different ways, such as by changing the color or brightness, lighting up other portions, dividing number portion 67B into parts and lighting them in sequence, etc. By performing such an operation, even on display unit 67 that can only display a limited number of numbers and letters, it is possible to prompt the user to press start button 16, which is the operation to start the tank clean course.

[0152] In this modification, the control unit 25 does not light up the start button 16, but the control unit 25 may also light up or flash the start button 16. The control unit 25 may keep the start button 16 lit during the acceptance process. This operation can further encourage the user to press the start button 16. Once pressed, the start button 16 may stop lighting up.

[0153] If 30 minutes have passed without the start button 16 being pressed (Yes in S27), the control unit 25 stops the notification by the buzzer 20 while displaying information about the tub clean course on the display unit 67. This display corresponds to the second display (S28). In the second display of this modification, as shown in FIG. 12B, the "3 hours and 00 minutes remaining" stops flashing in the numeric portion 67B and remains lit continuously. This operation can suggest that the tub clean course is set to a user who has forgotten the current status of the washer-dryer 1 after the predetermined time has passed, while preventing the user from mistaking the notification by the buzzer 20 or the flashing display in the numeric portion 67B as an abnormality notification in the washer-dryer 1.

[0154] On the other hand, if the controller 25 receives a press of the start button 16, which is an instruction to start the tank clean course, during the reception process (Yes in S22 or S31), the controller 25 changes the display mode of the tank clean course information from the display mode of the second display. Specifically, the controller 25 lights up the remaining time of the tank clean course in the numeric portion 67B of the display unit 67 and executes the tank clean course. Furthermore, the controller 25 flashes the tank mold sterilization 67AA while the tank clean course is being executed. This operation allows the user to recognize that the tank clean course has started, using only the limited display unit 67. Note that, when the controller 25 receives a press of the start button 16, the controller 25 may return the display mode of the tank clean course information to the display mode before detecting the open state of the lid 4.

[0155] The washing machine in the first aspect comprises a washing tub for storing laundry, an outer tub with the washing tub rotatably housed inside, a housing that elastically supports the outer tub, a motor for rotating the washing tub, a lid for opening and closing the housing opening for loading and unloading laundry, a reception unit that receives in advance the course to be executed by the user, and a control unit that executes the course, the courses including a main operation having a spin-drying process and a post-process course that is executed after the main operation and involves driving the motor, and the control unit does not execute the post-process course after the main operation until it receives an instruction to start the post-process course.

[0157] In a third aspect, the washing machine in the second aspect further has a display unit capable of displaying any letters or numbers, and the control unit causes the display unit to display, during the reception process, that the post-process course will be executed.

[0158] As a washing machine in a fourth aspect, in the washing machine in the third aspect, during the reception process, a message indicating that the main operation has ended and a message indicating that the post-process course will be executed are displayed on the same screen.

[0159] In a fifth aspect of the washing machine, when the lid opening / closing detection means detects the opening or closing of the lid in the washing machine of the fourth aspect, the display indicating that the main operation has ended is stopped and a message is displayed prompting the user to start a subsequent process course.

[0160] In the washing machine of the sixth aspect, in the washing machine of the fifth aspect, after a predetermined time has elapsed since the display prompting the user to start the post-process course, a display indicating that the main operation has ended, a display indicating that the post-process course will be executed, and a display prompting the user to start the post-process course are displayed on the same screen.

[0161] As a washing machine in a seventh aspect, in the washing machine in any of the third to sixth aspects, an audio output unit is further provided, and if the control unit does not receive an instruction to start the post-process course after a first predetermined time has elapsed, it makes an alert via the audio output unit, and if the control unit does not receive an instruction to start the post-process course after a second predetermined time has elapsed, it stops making alerts via the audio output unit and displays on the same screen a message indicating that the post-process course will be executed and a message urging the control unit to give an instruction to start the post-process course.

[0162] In an eighth aspect, the washing machine is a washing machine according to any one of the first to seventh aspects, further comprising a start button for instructing the start of a post-process course, the reception unit and the start button being arranged apart from each other.

[0163] In a ninth aspect, the washing machine is the washing machine of the second aspect, further comprising a display unit that displays specified numbers and letters, and the control unit causes the display unit to display information about the post-process course during the reception process.

[0164] In a tenth aspect of the invention, the control unit of the washing machine of the ninth aspect, when detecting that the lid is open, causes the display unit to display information about the post-process course.

[0165] In the washing machine of the eleventh aspect, in the washing machine of the ninth or tenth aspect, when the control unit detects that the lid is open and then detects that the lid is closed, the control unit changes the display mode of the information for the post-process course.
