For example, there may be cases where detailed explanations of already well-known matters or duplicate explanations for substantially the same configurations are omitted. Note that the attached drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims by these.

[0010] (Embodiment 1) [1-1. Configuration] [1-1-1. Configuration of the maintenance notification system] FIG. 1 is a diagram showing the configuration of a maintenance notification system 1000. The maintenance notification system 1000 is a system that notifies a user P of the washing and drying machine 1 of information regarding the washing and drying machine 1. In the present embodiment, the maintenance notification system 1000 notifies, as information regarding the washing and drying machine 1, information regarding the maintenance of the heat pump apparatus 113C (see FIG. 4) and information regarding an error occurring in the washing and drying machine 1. Hereinafter, information regarding the maintenance of the heat pump apparatus 113C will be referred to as "maintenance information". Also, information regarding an error occurring in the washing and drying machine 1 will be referred to as "error information". The washing and drying machine 1 is an example of a "clothing treatment apparatus".

[0011] The maintenance notification system 1000 includes a washing and drying machine 1. The washing and drying machine 1 is a device that performs processes such as washing and drying on the clothing PO housed in the washing tub 15. In the present embodiment, a drum-type washing and drying machine is exemplified as the washing and drying machine 1. Note that in FIG. 1, the case where the washing and drying machine 1 is installed inside the facility H is exemplified, but the washing and drying machine 1 may be installed outside the facility H.

[0012] The washing and drying machine 1 communicates with a first server 3 that is connected to a network NW, which is a WAN (Wide Area Network), via a communication device 2. The first server 3 is an example of an "output unit".

[0013] The communication device 2 is connected to the network NW and communicates with devices connected to the network NW. The communication device 2 functions as an interface device for connecting the washing and drying machine 1 and the terminal device 4 to the network NW. The communication device 2 constructs a local network in the facility H. The terminal device 4 is an example of a "display unit".

[0014] The maintenance notification system 1000 includes a terminal device 4. The terminal device 4 is a PC (Personal Computer) such as a smartphone or a tablet terminal. The terminal device 4 has an application program related to the washing and drying machine 1 installed thereon, and communicates with the first server 3 and the second server 5 by the functions of this application program. In the following description, the application program related to the washing and drying machine 1 is appropriately expressed as "APP411" with the symbol "411" attached.

[0015] In Figure 1, users P located inside facility H are shown with solid lines, and users P located outside facility H are shown with dotted lines. When terminal device 4 is used by user P inside facility H, it communicates with devices connected to the network NW either via communication device 2 or without communication device 2. When terminal device 4 is used by user P outside facility H and cannot establish a communication connection with communication device 2, it communicates with devices connected to the network NW without communication device 2.

[0016] The maintenance notification system 1000 includes a first server 3. The first server 3 is a server device that processes information using the washing machine / dryer 1 and the terminal device 4 as clients. The first server 3 is connected to the network NW and communicates with the washing machine / dryer 1 and the terminal device 4.

[0017] The maintenance notification system 1000 includes a second server 5. The second server 5 is a server device that processes information using terminal device 4 as a client. The second server 5 is connected to the network NW. The second server 5 functions as a web server and communicates with terminal device 4.

[0018] [1-1-2. Washer-dryer configuration] Next, the configuration of the washing machine and dryer 1 will be explained with reference to Figures 2-5. Figures 2-4 illustrate the X, Y, and Z axes. The X, Y, and Z axes are orthogonal to each other. The Z axis indicates the vertical direction and corresponds to the height direction of the washing machine 1 in its installed state. The X and Y axes are parallel to the horizontal direction. The X axis indicates the left-right direction. The left-right direction corresponds to the left-right direction of the washing machine 1 in its installed state. The Y axis indicates the front-back direction. The positive direction of the X axis is to the right. The positive direction of the Y axis is forward. The positive direction of the Z axis is upward.

[0019] Figure 2 is a schematic cross-sectional view showing the configuration of the washing machine 1. Note that Figure 2 is merely a schematic diagram illustrating the configuration of the washer-dryer 1, and the installation location and size of each component of the washer-dryer 1 are not limited to those shown in Figure 2.

[0020] As shown in Figure 2, the washing and drying machine 1 comprises a housing 10, a drying mechanism 11, and a control device 12.

[0021] The housing 10 is a component that forms the outer casing of the washing machine 1 and includes a top surface portion 13 that constitutes the top surface of the washing machine 1. Inside the housing 10 are a water tank 14 with an open front and capable of storing water, and a washing tub 15 that is rotatably mounted inside the water tank 14. The peripheral wall of the washing tub 15 is provided with numerous ventilation holes 16 that connect the inside and outside of the washing tub 15. A drive motor 17 is provided in the lower inner part of the housing 10. The drive motor 17 is connected to the washing tub 15 via a belt 18 and a pulley 19. When the drive motor 17 is driven, the washing tub 15 rotates around its central axis CA as the axis of rotation. The washing tub 15 is an example of a "storage tub".

[0022] A door 20 for opening and closing the aquarium 14 is provided on the front of the housing 10. An operation display unit 21 is also provided on the upper front of the housing 10. The operation display unit 21 receives instruction input from the user P and displays information. In this embodiment, the operation display unit 21 is exemplified as being composed of a touch panel, but the operation display unit 21 may be composed of a 7-segment display and physical buttons, or a combination of a touch panel and physical buttons.

[0023] The drying mechanism 11 is located in the upper interior part of the housing 10. The drying mechanism 11 comprises a drying path 111, a drying filter 112, a heat pump unit 113, and a fan case 114.

[0024] The drying path 111 consists of an inlet path 111A and an outlet path 111B. The inlet path 111A and the outlet path 111B are paths connecting the water tank 14 and the heat pump unit 113. The inlet path 111A is the path through which air flows into the heat pump unit 113 from the top of the water tank 14. A drying filter 112 is provided in the middle of the inlet path 111A to collect lint contained in the air flowing from the water tank 14 into the heat pump unit 113. The outlet path 111B is the path through which air flows out from the heat pump unit 113 to the back of the water tank 14. The outlet path 111B includes a fan case 114 that encloses a blower fan 115. The fan case 114 is located downstream of the heat pump unit 113 in the direction of airflow. When the blower fan 115 is driven, the washing machine 1 generates an airflow that "flows out of the water tank 14, passes through the inlet path 111A → heat pump unit 113 → outlet path 111B in that order, and flows back into the water tank 14."

[0025] The heat pump unit 113 will be described in detail with reference to Figures 3 and 4. Figure 3 is a perspective view of the washing machine 1 with the top panel 13 removed. Figure 4 is an exploded perspective view of the heat pump unit 113.

[0026] As shown in Figure 3, the heat pump unit 113 is located below the top surface 13. When the top surface 13 is removed from the washing machine 1, the heat pump unit 113 is exposed on the top surface.

[0027] As shown in Figure 4, the heat pump unit 113 includes a case body 113A, a case lid 113B, and a heat pump device 113C. The case body 113A is formed in a roughly box shape with an open top and houses the heat pump device 113C. The case lid 113B closes the opening on the top of the case body 113A and covers the top of the heat pump device 113C. An inlet connection port 113D is formed on the front of the case body 113A to which the inlet path 111A is connected, and an outlet connection port 113E is formed on the rear of the case body 113A to which the fan case 114 of the outlet path 111B is connected. The case body 113A houses the heat pump device 113C by inserting it into the case body 113A from above and downward. The case body 113A can be removed by lifting the heat pump device 113C upward relative to the case body 113A.

[0028] The heat pump device 113C comprises a compressor 113F for compressing a refrigerant, a heat exchanger 113G for dehumidifying and heating air, and a pipeline 113H connecting the compressor 113F and the heat exchanger 113G, through which the refrigerant passes. The heat exchanger 113G comprises an evaporator 113I for dehumidifying air and a condenser 113J for heating air.

[0029] In the water tank 14, the low-temperature, high-humidity air from which moisture has been removed from the clothing PO passes through the drying filter 112 to remove lint. This lint-free air then passes through the evaporator 113I to be dehumidified, becoming low-temperature, low-humidity air. It is then heated in the condenser 113J to become high-temperature, low-humidity air. This high-temperature, low-humidity air then becomes drying air for drying the clothing PO, passing through the outlet path 111B and flowing back into the water tank 14. In this way, the heat pump device 113C generates drying air.

[0030] While most of the lint is removed by the drying filter 112, some fine lint particles pass through without being captured by the drying filter 112 and adhere to the front surface of the fins 113K of the evaporator 113I. When lint adheres to and accumulates on the front surface of the fins 113K, the airflow rate that can flow into the evaporator 113I decreases, which in turn reduces the airflow rate that can pass through the heat exchanger 113G, thus degrading the drying performance. Therefore, maintenance such as lifting the heat exchanger 113G upwards from the case body 113A and cleaning the front surface of the fins 113K to remove the accumulated lint is necessary. During maintenance of the heat pump unit 113C, the service technician removes the top section 13 from the housing 10, removes the case cover 113B from the case body 113A of the heat pump unit 113, and lifts the heat pump unit 113C from the case body 113A using a jig (not shown). With the heat pump unit 113C lifted using the jig, the service technician cleans the front surface of the fins 113K of the evaporator 113I and removes any lint adhering to the fins 113K.

[0031] As shown in Figure 2, the control device 12 is housed in the lower part of the housing 10 and controls various parts of the washing machine 1. Details of the control device 12 will be explained with reference to Figure 5.

[0032] Figure 5 shows the configuration related to the control of the washing machine / dryer 1. The control device 12 includes a processor 120 such as a CPU (Central Processing Unit) or MPU (Micro Processing Unit), memory 130, and interface circuits to which other devices and sensors are connected.

[0033] Memory 130 is a storage device that stores programs and data. Memory 130 stores control programs 131, device IDs (Identification) 132, and other data processed by the processor 120. Memory 130 has a non-volatile storage area. Memory 130 also has a volatile storage area and constitutes the work area of ​​the processor 120. Memory 130 is composed of, for example, ROM (Read Only Memory) and RAM (Random Access Memory). The control program 131 is a program that is read by the processor 120 and executed. Equipment ID 132 is identification information that uniquely identifies washing machine / dryer 1.

[0034] The control device 12 is connected to a communication unit 22, a drive motor 17, an operation display unit 21, a fan motor 23, a detection unit 24, and a compressor 113F. Other devices, such as a drain valve and a water supply valve, are also connected to the control device 12.

[0035] The communication unit 22 is equipped with hardware such as communication circuits and antennas, and communicates with devices connected to the network NW in accordance with a predetermined communication standard. The fan motor 23 is a motor that rotates the blower fan 115 and is connected to the blower fan 115. The detection unit 24 consists of a current detector and detects the current value of the fan motor 23.

[0036] The control device 12 executes various driving courses in various driving modes by having the processor 120 execute the control program 131.

[0037] The control device 12 can execute various operating courses, including washing courses, wash-and-dry courses, and drying courses. The washing course is, for example, an operating course consisting of a washing process, a rinsing process, and a spin-drying process. The control device 12 controls the drive motor 17, a drain valve (not shown), a water supply valve (not shown), etc., to execute the washing course. Furthermore, the wash-and-dry course is an operating course that includes a drying process in addition to the processes of the washing course. The control device 12 further controls the fan motor 23 and the compressor 113F to execute the wash-and-dry course. Furthermore, the drying course is an operating course consisting of a drying process and a blowing process. The control device 12 controls the drive motor 17, the fan motor 23, and the compressor 113F to execute the drying course.

[0038] The operating modes that the control device 12 can execute include, for the drying process, "standard," "thorough," and "energy-saving." In the "Thorough" mode, the drying process results in a higher degree of dryness than in the "Standard" mode. In the "Energy Saving" mode, the drying process consumes less power than in other modes.

[0039] The control device 12 communicates with the first server 3 via the communication unit 22. In this embodiment, the control device 12 transmits operation data D1 to the first server 3 each time it executes an operation course that includes a drying process. Operation data D1 is data related to the most recent operation. Operation data D1 includes equipment ID 132. Operation data D1 also includes information such as the type of operation course, the type of operation mode, and the date and time the operation was performed. The date and time the operation was performed may be the start date and time of the operation, the end date and time of the operation, or both. Operation data D1 also includes current value time series data. Current value time series data is data that shows the current value of the fan motor 23 in a time series during the drying process. During the execution of the drying process, the control device 12 acquires the current value detected by the detection unit 24 from the detection unit 24 and generates current value time series data.

[0040] Furthermore, in this embodiment, if an error occurs in the washing machine 1 that is difficult for the user P to resolve, the control device 12 transmits error occurrence data D2 to the first server 3 at a predetermined interval. Error data D2 indicates that an error occurred in washing machine 1. Error data D2 includes the device ID 132. Error data D2 also includes the date and time it was sent. The error occurrence data D2 may be sent from the control device 12 to the first server 3 each time an error occurs in the washing machine 1, or it may be sent to the first server 3 when the operation of the washing machine 1 is completed.

[0041] [1-1-3. Terminal Device Configuration] Next, we will describe the configuration of terminal device 4. Figure 6 shows the configuration of terminal device 4. The terminal device 4 comprises a terminal control unit 40, a terminal communication unit 41, and a touch panel 42.

[0042] The terminal control unit 40 includes a processor 400 such as a CPU or MPU, memory 410, and interface circuits to which other devices are connected. In this embodiment, the case in which the terminal communication unit 41 and the touch panel 42 are connected to the terminal control unit 40 is illustrated, but other devices may be connected to the terminal control unit 40.

[0043] Memory 410 is a storage device that stores programs and data. Memory 410 stores data processed by APP 411 and processor 400. Memory 410 has non-volatile storage areas. It also has volatile storage areas that constitute the work area of ​​processor 400. Memory 410 is composed of, for example, ROM and RAM.

[0044] The terminal communication unit 41 is equipped with hardware such as wireless communication circuits and antennas, and communicates with devices connected to the network NW according to the control of the terminal control unit 40. The touch panel 42 comprises a display panel and a touch sensor that is superimposed on or integrated with the display panel.

[0045] The processor 400 communicates with the first server 3 and the second server 5 via the terminal communication unit 41 by executing APP 411. Furthermore, the processor 400 executes APP 411 to display various information on the touch panel 42. Furthermore, the processor 400 accepts user P's input via the touch panel 42 by executing APP 411.

[0046] [1-1-4. Configuration of the first server] Next, we will describe the configuration of Server 1, Server 3. Figure 7 shows the configuration of the first server 3. The first server 3 comprises a server control unit 30 and a server communication unit 31.

[0047] The server control unit 30 includes a processor 300 such as a CPU or MPU, memory 310, and interface circuits to which other devices are connected. The server communication unit 31 is connected to the server control unit 30.

[0048] Memory 310 is a storage device that stores programs and data. Memory 310 stores control programs 311, databases 312, and data processed by the processor 300. Memory 310 has non-volatile storage areas. It also has volatile storage areas that constitute the work area of ​​the processor 300. Memory 310 is composed of, for example, ROM or RAM. The control program 311 is a program that is read by the processor 300 and executed.

[0049] Database 312 is a database that stores a record R for each washing machine / dryer 1. Record R contains device ID 132. Record R also includes the registration date as information. This registration date is the date on which user P registered for notification services such as maintenance information. This registration date could be the date user P purchased washing machine 1, or the date user P started using washing machine 1. Record R also contains communication information for communicating with terminal device 4. An example of this communication information is an address. Additionally, record R contains the model number of washing machine 1 as information. Record R also contains the first stored data. The first stored data is data that stores the operation data D1 in the order in which the operation data D1 was received. Record R also contains second-order stored data. This second-order stored data stores the error occurrence data D2 in the order in which it was received.

[0050] In this embodiment, some of the information or data contained in record R may be stored in a separate database. For example, the first stored data and the second stored data of record R may be stored in a database other than database 312.

[0051] The server communication unit 31 is equipped with hardware such as wireless communication circuits and antennas, and communicates with devices connected to the network NW according to the control of the server control unit 30.

[0052] The server control unit 30 communicates with the washing machine / dryer 1 and the terminal device 4 via the server communication unit 31 by having the processor 300 execute the control program 311.

[0053] Furthermore, the server control unit 30 processes record R by having the processor 300 execute the control program 311. More specifically, when the server control unit 30 receives operation data D1 from the washing machine 1, it identifies the record R of equipment ID 132 included in the received operation data D1 from the database 312. Next, the server control unit 30 stores the received operation data D1 in the first stored data of the identified record R. Furthermore, when the server control unit 30 receives error data D2 from the washing machine 1, it identifies the record R of equipment ID 132 included in the received error data D2 from the database 312. Next, the server control unit 30 stores the received error data D2 in the second stored data of the identified record R.

[0054] Furthermore, the server control unit 30 executes the operations of the flowchart described later when the processor 300 executes the control program 311.

[0055] [1-2. Operation] Next, the operation of each part of the maintenance notification system 1000 will be described. Figure 8 is a flowchart showing the operation of the first server 3. The operations shown in Figure 8 are performed for each record R stored in the database 312.

[0056] The server control unit 30 determines whether or not to start processing (step SA1). For example, if a predetermined cycle arrives, the server control unit 30 determines in step SA1 to start processing.

[0057] If the server control unit 30 determines to start processing (step SA1: YES), it refers to the target record R and identifies the most frequently set operating condition in the first period (step SA2). In this embodiment, the operating condition is a combination of the operating course and the operating mode. Hereinafter, the operating conditions that were set most frequently during the first period will be referred to as the "most frequent operating conditions."

[0058] Now, let's explain the first period. The first period is a predetermined period immediately preceding the present. In this embodiment, the first period is exemplified as the two weeks immediately preceding the present, but the first period is not limited to the two weeks immediately preceding the present; it could be the one week immediately preceding the present, the three weeks immediately preceding the present, or the four weeks immediately preceding the present. Furthermore, the first period does not have to be based on the present. For example, the first period could be a predetermined period based on two days ago.

[0059] Step SA2 will be described in detail. The server control unit 30 identifies the operation data D1 for the first period from the first stored data of the target record R. This identification is performed based on the operation execution date and time included in the operation data D1. Next, the server control unit 30 refers to the operation data D1 for the first period to identify the most frequent operating condition. For example, suppose the operation data D1 for the first period includes 5 operation data D1 entries that include the drying course and the "energy-saving" operating mode, and 12 operation data D1 entries that include the wash-and-dry course and the "energy-saving" operating mode. In this example, the server control unit 30 identifies the most frequent operating condition as the combination of the wash-and-dry course and the "energy-saving" operating mode.

[0060] The server control unit 30 identifies the most frequent operating conditions and calculates a first current value (step SA3).

[0061] Now, let's explain the first current value. In this embodiment, the first current value is the average value of the current values ​​detected by the detection unit 24 during the first period. More specifically, the first current value is the average of the current values ​​shown by the time-series data of current values ​​obtained from all of the operation data D1, including the most frequent operation conditions, during the first period.

[0062] Referring to Figure 9, the calculation of the first current value in this embodiment will be described in detail. Figure 9 is a diagram illustrating the calculation of the first current value in this embodiment.

[0063] Figure 9 illustrates a case where 13 operational data points D1 from the target record R for the first period have been identified. In Figure 9, the number following D1 indicates which operational data point D1 it is, counting from the current point. Furthermore, Figure 9 illustrates the case where the most frequent operating condition is a combination of the wash-and-dry course and the "energy-saving" operating mode. Furthermore, Figure 9 illustrates a case where, out of 13 operating data points D1, 8 of them contain the most frequent operating conditions.

[0064] In the example shown in Figure 9, the server control unit 30 identifies eight operation data D1s from the thirteen operation data D1s that contain the most frequent operation conditions. These eight operation data D1s include operation data D1 and D113, but do not include operation data D17. Next, in the example shown in Figure 9, the server control unit 30 reads current value time series data from each of the eight identified operating data D1, and calculates a first current value by averaging the current values ​​indicated by all the read current value time series data. In this embodiment, the first current value was described as the average of the current values ​​shown in the time-series data of current values ​​obtained from all of the operating data D1, including the most frequent operating conditions, during the first period. However, the first current value is not limited to the average value and may be calculated from the maximum value, mode, etc.

[0065] Returning to the explanation in Figure 8, the server control unit 30 calculates the first current value and then calculates the second current value (step SA4).

[0066] Here, we will explain the second current value and then describe step SA4 in detail. The server control unit 30 identifies the operation data D1 for the second period, which includes the most frequent operation conditions, from the target record R.

[0067] The second period is a period that includes a period prior to the first period. In this embodiment, the second period includes the first period and a period prior to the first period, and is longer than the first period. In this embodiment, the second period is exemplified as the period from the present to the past three years, but the second period is not limited to the period from the present to the past three years, and may be, for example, the period from the present to the past six months, or the period from the present to the past one year. Also, the second period may be the period from the present to the date of the first operation.

[0068] When the server control unit 30 identifies the operation data D1 for the second period that includes the most frequent operation conditions, it calculates the second current value by referring to the identified operation data D1.

[0069] In this embodiment, the second current value is the average value of the current values ​​detected by the detection unit 24 in one of the multiple predetermined period PP divisions of the second period. More specifically, the second current value is the average of the largest value among the average values ​​of the current values ​​obtained for each predetermined period PP that divides the second period. In this embodiment, the average value is used as an example for the second current value, but the second current value is not limited to the average value, and may be the largest value among the maximum value or mode obtained for each predetermined period PP.

[0070] Referring to Figure 10, the calculation of the second current value in this embodiment will be described in detail. Figure 10 is a diagram illustrating the calculation of the second current value in this embodiment.

[0071] Each of the operating data D1 shown in Figure 10 is the operating data D1 that includes the most frequent operating conditions. Furthermore, Figure 10 illustrates the second period as the three-year period from the present. Furthermore, Figure 10 illustrates a case where two weeks is used as a predetermined period PP to divide the second period into multiple segments, and the second period is divided into 72 segments by these predetermined period PPs. In Figure 10, the number following "PP" indicates which predetermined period PP is currently being used. Furthermore, Figure 10 illustrates a case where the first stored data of the target record R contains operating data D1 for the past two years from the present. Therefore, in Figure 10, operating data D1 for the predetermined period PP49 to predetermined period PP72 is not stored.

[0072] In the example shown in Figure 10, the server control unit 30 reads current value time series data from each of the operating data D1, including the most frequent operating conditions, for each predetermined period PP, and averages the current values ​​indicated by all the read current value time series data. In this way, the server control unit 30 calculates the average current value for each of the 72 predetermined period PPs. Next, the server control unit 30 calculates the second current value by selecting the average value with the largest value among the 72 calculated average values. In the explanation of Figure 10, it is assumed that the average value calculated for a predetermined period PP48 is the largest value among the predetermined period PP1 to predetermined period PP48. Therefore, in the example of Figure 10, the server control unit 30 calculates the average value of the predetermined period PP48 as the second current value.

[0073] Returning to the explanation of Figure 8, the server control unit 30 calculates the second current value and then calculates the attenuation rate of the first current value relative to the second current value based on the following formula (1) (step SA5). Attenuation rate = 1 - (1st current value / 2nd current value) ... (1) The attenuation rate may also be calculated as a percentage.

[0074] Next, the server control unit 30 refers to the second stored data of the target record R and obtains error occurrence data D2 for a predetermined period from the present (step SA6). This predetermined period is shorter than the first period, for example, 24 hours.

[0075] Next, the server control unit 30 refers to the registration date included in the target record R and determines whether a predetermined period (referred to as the first predetermined period) has elapsed since the registration date (step SA7). This first predetermined period is a longer period than the first period and is the period for which the diagnostic result screen SG, described later, is displayed. For example, it may be the warranty period of the heat pump device 113C. For example, a warranty period of 3 years can be given for the heat pump device 113C.

[0076] If the server control unit 30 determines that the first predetermined period has elapsed since the registration date (step SA7YES), it terminates this process, indicating that the first predetermined period has not yet passed.

[0077] On the other hand, if the server control unit 30 determines that the first predetermined period has not elapsed since the registration date (step SA7: NO), it determines whether or not an error has occurred in the washing machine 1 (step SA8). If the server control unit 30 was able to obtain the error occurrence data D2 in step SA6, it makes a positive determination in step SA8; if it was not able to obtain the error occurrence data D2 in step SA6, it makes a negative determination in step SA8.

[0078] If the server control unit 30 determines that no error has occurred in the washing machine 1 (step SA8: NO), it determines the maintenance requirement level based on the attenuation rate calculated in step SA5 (step SA9).

[0079] The maintenance requirement level indicates the degree to which the heat pump unit 113C requires maintenance. In this embodiment, the maintenance requirement level is one of five levels: Level 1, Level 2, Level 3, Level 4, and Level 5. The higher the number following the word "Level," the greater the degree to which maintenance is required.

[0080] Step SA9 will be described in detail. The server control unit 30 determines that the maintenance requirement level is level 1 if the attenuation rate calculated in step SA5 is less than or equal to the first threshold. Furthermore, the server control unit 30 determines that the maintenance requirement level is level 2 if the attenuation rate calculated in step SA5 is greater than the first threshold and less than or equal to the second threshold. The second threshold is a value greater than the first threshold. Furthermore, the server control unit 30 determines that the maintenance requirement level is level 3 if the attenuation rate calculated in step SA5 is greater than the second threshold and less than or equal to the third threshold. The third threshold is a value greater than the second threshold. Furthermore, the server control unit 30 determines that the maintenance requirement level is level 4 if the attenuation rate calculated in step SA5 is greater than the third threshold and less than or equal to the fourth threshold. The fourth threshold is a value greater than the third threshold. Furthermore, if the attenuation rate calculated in step SA5 is greater than the fourth threshold, the server control unit 30 determines that the maintenance required level is level 5. The second threshold is an example of a "predetermined value".

[0081] Thus, the server control unit 30 determines a higher maintenance requirement level the greater the attenuation rate, or in other words, the lower the average current value of the fan motor 23 during the first period. When lint adheres to and accumulates on the front surface of the fins 113K of the evaporator 113I, the airflow rate that can flow into the evaporator 113I decreases, and the airflow rate that can pass through the heat exchanger 113G decreases. When the airflow rate that can pass through the heat exchanger 113G decreases, the airflow rate pushed out by the blower fan 115 decreases, and the current value of the fan motor 23 decreases. Therefore, the server control unit 30 can properly determine the maintenance requirement level by determining the maintenance requirement level based on the attenuation rate as described above.

[0082] When the server control unit 30 determines the maintenance requirement level, it generates a URL with a first parameter (Uniform Resource Locator) (step SA10).

[0083] The URL with the first parameter is a URL that contains maintenance information. The maintenance information included in the URL with the first parameter contains the first period, the registration date included in the target record R, the part number included in the target record R, and the maintenance requirement level determined in step SA9.

[0084] When the server control unit 30 generates a URL with the first parameter, it sends the generated URL with the first parameter to the terminal device 4 (step SA11). This causes the server control unit 30 to output maintenance information to the terminal device 4. The transmission in step SA11 is performed based on the communication information contained in the target record R.

[0085] Returning to the explanation of step SA8, if the server control unit 30 determines that an error has occurred in the washing machine 1 (step SA8: NO), it generates a URL with a second parameter (step SA12).

[0086] A URL with a second parameter is a URL that contains error information. The error information included in the URL with the second parameter contains the first period, the registration date included in the target record R, the product number included in the target record R, and a statement indicating that an error has occurred.

[0087] When the server control unit 30 generates a URL with a second parameter, it sends the generated URL with the second parameter to the terminal device 4 (step SA13). As a result, the server control unit 30 outputs error information to the terminal device 4. The transmission in step SA13 is performed based on the communication information contained in the target record R.

[0088] Next, with reference to Figure 11, the operation of the maintenance notification system 1000 when the first server 3 sends a URL with a first parameter or a URL with a second parameter will be described.

[0089] Figure 11 is a sequence diagram showing the operation of the first server 3, terminal device 4, and second server 5.

[0090] When the first server 3 sends a URL with a first parameter or a URL with a second parameter (step SB1), the terminal control unit 40 receives the URL with a first parameter or a URL with a second parameter from the first server 3 (step SB2).

[0091] Next, the terminal control unit 40 displays a notification screen TG on the touch panel 42 indicating that there is a notification for user P (step SB3).

[0092] Figure 12 shows an example of the notification screen TG. The notification screen TG displays multiple icon ICs, including icon IC1. Icon IC1 is an icon that indicates that user P has a notification when terminal device 4 receives a URL with a first parameter or a URL with a second parameter. For example, as shown in Figure 12, icon IC1 indicates that user P has a notification by displaying the string "You have a notification!". Icon ICs are selectable. When icon IC1 is selected, terminal control unit 40 receives an instruction to display a notification to user P (hereinafter referred to as "notification display instruction").

[0093] Returning to the explanation of Figure 11, when the terminal control unit 40 receives a notification display instruction via the notification screen TG (step SB4), it sends a request to the second server 5 requesting screen data (step SB5). If terminal device 4 receives a URL with a first parameter, the request sent in step SB5 will include maintenance information for the received URL with the first parameter. If terminal device 4 receives a URL with a second parameter, the request sent in step SB5 will include error information for the received URL with the second parameter.

[0094] When the second server 5 receives a request, it generates screen data corresponding to the request (step SB6). In step SB6, if the second server 5 receives a request containing maintenance information, it generates screen data for the diagnostic results screen SG, which will be described later. More specifically, if the second server 5 receives a request containing a maintenance requirement level of level 1 or level 2, it generates screen data for the first diagnostic results screen SG1, which will be described later. Furthermore, if the second server 5 receives a request containing a maintenance requirement level of level 3 or higher, it generates screen data for the second diagnostic results screen SG2, which will be described later. Furthermore, in step SB6, if the second server 5 receives a request containing error information, it generates screen data for the error screen EG.

[0095] The second server 5 sends a response containing the screen data generated in step SB6 to the terminal device 4 (step SB7).

[0096] When the terminal control unit 40 receives a response from the second server 5 (step SB8), it displays the screen indicated by the screen data included in the response on the touch panel 42 (step SB9).

[0097] In step SB9, the terminal control unit 40 displays either the first diagnostic result screen SG1, the second diagnostic result screen SG2, or the error screen EG on the touch panel 42.

[0098] Figure 13 shows an example of the first diagnostic results screen SG1. Figure 14 shows an example of the second diagnostic results screen SG2. The first diagnostic result screen SG1 and the second diagnostic result screen SG2 are both diagnostic result screens SG. The diagnostic result screens SG are screens that show the diagnostic results related to the drying mechanism 11 of the washing machine 1.

[0099] The diagnostic results screen SG displays maintenance information. The maintenance information displayed on the diagnostic results screen SG includes diagnostic period information J1, part number information J2, registration date information J3, and level correspondence information J4.

[0100] The diagnostic period information J1 indicates the period during which the drying mechanism 11 of the washing machine 1 was diagnosed. The diagnostic period information J1 indicates the first period included in the URL with the first parameter. In the examples in Figures 13 and 14, the string "2024 / 12 / 6-2024 / 12 / 20" is the diagnostic period information J1.

[0101] Part number information J2 is information that indicates the part number. Part number information J2 indicates the part number included in the URL with the first parameter. In the examples in Figures 13 and 14, the string "Part Number A" is part number information J2.

[0102] Registration date information J3 is information indicating the registration date. Registration date information J3 indicates the registration date included in the URL with the first parameter. In the examples in Figures 13 and 14, the string "2022 / 12 / 1" is registration date information J3.

[0103] Level correspondence information J4 is information corresponding to the maintenance requirement level included in the URL with the first parameter. Level correspondence information J4 includes the first comment information J41, the first image G1, the second image G2, and the second comment information J42.

[0104] The first comment information, J41, is information indicating comments on the diagnostic results of the drying mechanism 11 of the washing machine 1.

[0105] The first comment information J41 displayed on the first diagnostic results screen SG1 is the same regardless of whether the maintenance requirement level included in the first parameterized URL is level 1 or level 2. In the example in Figure 13, the first comment information J41 displayed on the first diagnostic results screen SG1 is the string "Proper maintenance has been performed."

[0106] The first comment information J41 displayed on the second diagnostic results screen SG2 differs depending on whether the maintenance requirement level included in the first parameterized URL is level 3 or level 4, or level 5. If the maintenance requirement level is level 3 or level 4, the first comment information J41 displayed on the second diagnostic results screen SG2 will be, for example, the string "We recommend cleaning the drying filter and drying path." If the maintenance requirement level is level 5, the first comment information J41 displayed on the second diagnostic results screen SG2 will be, for example, the string "We strongly recommend cleaning the drying filter and drying path."

[0107] Image 1G1 is a schematic representation of the drying mechanism 11. The first image G1 displayed on the second diagnostic results screen SG2 includes an image G3 that resembles a clump of lint, compared to the first image G1 displayed on the first diagnostic results screen SG1. The size of image G3 may be increased as the maintenance requirement level included in the first parameter URL increases.

[0108] Image 2G2 shows the degree of care and maintenance performed on the drying mechanism 11. In other words, Image 2G2 shows the degree of airflow in the drying mechanism 11. If the drying mechanism 11 is not properly cared for and maintained, the airflow in the drying mechanism 11 will decrease. The second image G2 displayed on the first diagnostic results screen SG1 is the same image regardless of whether the maintenance requirement level included in the first parameter URL is level 1 or level 2.

[0109] The second image G2 displayed on the second diagnostic results screen SG2 is different depending on whether the maintenance requirement level included in the first parameter URL is level 3, level 4, or level 5. When the maintenance requirement level is level 3, the second image G2 displayed on the second diagnostic results screen SG2 indicates that the degree of cleaning and maintenance is lower than when the maintenance requirement level is level 1 or 2, and that the level of cleanliness is higher than when the maintenance requirement level is level 4 or 5. When the maintenance requirement level is level 4, the second image G2 displayed on the second diagnostic results screen SG2 indicates that the degree of care and maintenance is lower than when the maintenance requirement level is level 3, and higher than when the maintenance requirement level is level 5. If the maintenance requirement level is level 4, the second image G2 displayed on the second diagnostic results screen SG2 is an image that indicates a lower level of care and maintenance than when the maintenance requirement level is level 4.

[0110] In this embodiment, the second image G2 indicates the degree of care and maintenance by the content and number of colored symbols. However, the second image G2 is not limited to the images shown in Figures 13 and 14, and can be any image that shows the degree of care and maintenance of the drying mechanism 11 according to the required maintenance level.

[0111] The second comment information J42 is information that shows comments regarding the diagnostic results of the drying mechanism 11 of the washing machine 1. The comments shown in the second comment information J42 are more detailed than the comments shown in the first comment information J41.

[0112] The second comment information J42 displayed on the first diagnostic results screen SG1 is the same text regardless of whether the maintenance requirement level included in the first parameterized URL is level 1 or level 2. In the example in Figure 13, the second comment information J42 displayed on the first diagnostic results screen SG1 contains the string, "Your washing machine is in good condition after being well cared for. Thank you for taking good care of it. Please use it with confidence." Also, the second comment information J42 displayed on the first diagnostic results screen SG1 contains the string, "Please continue to perform maintenance according to these procedures." Thus, the second comment information J42 displayed on the first diagnostic results screen SG1 prompts user P to perform maintenance on the washing machine 1.

[0113] The second comment information J42 displayed on the second diagnostic results screen SG2 differs depending on whether the maintenance requirement level included in the first parameterized URL is level 3, level 4, or level 5. If the maintenance requirement level is level 3, the second comment information J42 displayed on the second diagnostic results screen SG2 will be a string of text such as, "Lint and dust have started to accumulate in the drying filter or drying path of your washing machine, and if you continue to use it in this condition, it may affect the drying performance. Please clean it according to the following procedure. If the problem persists, we recommend that you apply for a professional heat pump cleaning service." If the maintenance requirement level is level 4, the second comment information J42 displayed on the second diagnostic results screen SG2 may contain text such as, "Lint and dust may be accumulating in the drying filter or drying path of your washing machine, potentially affecting drying performance. Please clean it according to the following procedure. If the problem persists, we recommend applying for a professional heat pump cleaning service." If the maintenance requirement level is level 5, the second comment information J42 displayed on the second diagnostic results screen SG2 will be a string of text such as, "Lint and dust are likely to be accumulating in the drying filter or drying path of your washing machine, which may be affecting drying performance. Please clean it according to the following procedure. If the problem persists, we recommend that you apply for a professional heat pump cleaning service." Thus, the second diagnostic results screen SG2 recommends using the maintenance service for washing machine 1.

[0114] Figure 15 shows an example of the error screen EG. The error screen EG is a screen that displays error information. The error information displayed on the error screen EG includes diagnostic period information J1, part number information J2, registration date information J3, third comment information J5, and fourth comment information J6.

[0115] The third comment information J5 indicates that an error has occurred in the washing machine / dryer 1. In the example in Figure 15, the third comment information J5 is the string "An error has been confirmed in the washing machine you are using."

[0116] The fourth comment information J6 indicates that the washing machine / dryer 1 requires inspection and repair. In the example in Figure 15, the fourth comment information J6 is the string "If H** is still displayed on the main unit panel, inspection and repair are required."

[0117] [1-3. Effects, etc.] As described above, the maintenance notification system 1000 for the washing machine 1 includes a washing tub 15 for containing clothes PO, a heat pump device 113C for generating drying air, a blower fan 115 for supplying drying air, a drying path 111 communicating with the washing tub 15, and a detection unit 24 for detecting the current value of the fan motor 23 of the blower fan 115. The maintenance notification system 1000 for the washing machine 1 includes a first server 3 that outputs information based on the current value detected by the detection unit 24. The maintenance notification system 1000 for the washing machine 1 also includes a terminal device 4 that displays information based on the information output by the first server 3. The first server 3 outputs maintenance information regarding the maintenance of the heat pump device 113C based on the current value over a predetermined period. The terminal device 4 displays the maintenance information.

[0118] According to this, if the current value of the fan motor 23 of the blower fan 115 decreases, there is a possibility that lint clogging is occurring in the heat pump device 113C, and maintenance information will be displayed. Therefore, maintenance of the heat pump device 113C can be prompted, which can help suppress the deterioration of the drying performance of the washing machine 1 or restore its drying performance.

[0119] The first server 3 compares a first current value relating to the current value during the first period with a second current value relating to the current value during the second period, which includes periods prior to the first period. The first server 3 also determines the maintenance information to output based on the comparison between the first and second current values.

[0120] This allows for a comparison between the first current value and the second current value, which represents a past current value, making it possible to detect a decrease in the current value of the fan motor 23. Therefore, maintenance information to be output can be determined in accordance with the decrease in the current value of the fan motor 23, thereby prompting maintenance of the heat pump device 113C. Consequently, this can contribute to preventing a decrease in the drying performance of the washing machine 1 or restoring its drying performance.

[0121] The second current value is the current value during the period with the highest current value among the multiple divisions of the second period.

[0122] This allows for comparison of current values ​​over different periods while suppressing variations in current values, making it possible to detect a decrease in the current value of the fan motor 23. Therefore, it is possible to better detect the decrease in the current value of the fan motor 23 and prompt maintenance of the heat pump device 113C.

[0123] The first server 3 outputs different maintenance information based on a comparison between the first current value and the second current value.

[0124] According to this, maintenance information can be displayed in accordance with the decrease in the current value of the fan motor 23. Therefore, it is possible to prompt appropriate maintenance of the heat pump device 113C.

[0125] The first server 3 outputs different maintenance information based on the attenuation rate of the first current value relative to the second current value.

[0126] This allows us to determine the degree of decrease in the current value of the fan motor 23, and therefore, the maintenance information output can be varied according to the degree of decrease in the current value of the fan motor 23. Thus, maintenance information corresponding to the degree of decrease in the current value of the fan motor 23 can be displayed.

[0127] If the attenuation rate is below the second threshold, terminal device 4 displays maintenance information prompting user P to perform maintenance on the washing machine 1. If the attenuation rate is greater than the second threshold, terminal device 4 displays maintenance information recommending the use of the washing machine 1 maintenance service.

[0128] According to this, if the attenuation rate is greater than the second threshold, it is recommended to use the maintenance service for the washing machine 1 and maintain the heat pump device 113, thus preventing unnecessary recommendations for using the maintenance service for the washing machine 1. Furthermore, if the attenuation rate is below the second threshold, it is highly likely that the reduced drying performance can be restored or the reduction in drying performance can be prevented by user P performing maintenance on the washing machine 1, thus encouraging user P to perform maintenance.

[0129] The first period is the most recent designated period based on the present.

[0130] According to this, a decrease in the current value of the most recent fan motor 23 can be detected, and the output maintenance information can be changed to correspond to the current value of the most recent fan motor 23.

[0131] If an error occurs in the washing machine / dryer 1, the first server 3 outputs error information related to the error occurring in the washing machine / dryer 1, prioritizing it over maintenance information. The terminal device 4 displays the error information.

[0132] According to this, if an error occurs in the washing machine / dryer 1, information regarding the error can be output, allowing the user P to be advised to resolve the error.

[0133] (Other embodiments) As described above, Embodiment 1 has been presented as an example disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in Embodiment 1 to create new embodiments. Therefore, other embodiments are described below as examples.

[0134] In the embodiment described above, if an error occurs in the washing machine 1, the error screen EG is displayed preferentially. In other embodiments, if an error occurs in the washing machine 1, the error screen EG may not be displayed. In these other embodiments, if the server control unit 30 determines that step SA8 is negative, it skips steps SA12 and SA13 and terminates the process.

[0135] In the embodiment described above, the maintenance requirement level is determined in five stages. In other embodiments, the maintenance requirement level may be determined in six or more stages, or in four or fewer stages.

[0136] In the embodiment described above, when calculating the second current value, the second period is divided into multiple predetermined periods PP. In other embodiments, some or all of the periods used to divide the second period may be irregular.

[0137] In the embodiment described above, the second current value is the largest average value among the average values ​​obtained for each predetermined period PP that divides the second period. In other embodiments, the second current value is not limited to the largest average value, but may be, for example, the second largest average value among the average values ​​obtained for each predetermined period PP that divides the second period.

[0138] In the embodiment described above, the most frequent operating condition was exemplified as the combination of the most frequently set operating course and operating mode during the first period. However, the most frequent operating condition is not limited to this condition; it is sufficient if the fluctuation of the current value of the fan motor 23 is similar across different current value time series data. For example, in another embodiment, the most frequent operating condition may be the operating course that is most frequently set during the first period. Furthermore, in other embodiments, for example, the most frequent operating condition may be the operating mode that is most frequently set during the first period. Furthermore, in other embodiments, for example, the most frequent operating condition may include the amount of clothing PO that was most frequently used in the first period for the combination of operating mode and operating course that was most often set during the first period. In this case, the operating data D1 includes the amount of clothing PO stored in the washing tub 15 as information. The reason why the amount of clothing PO may be included in the most frequent operating condition is that the amount of drying air changes depending on the amount of clothing PO, and the current value of the fan motor 23 of the blower fan 115 also changes. Furthermore, in other embodiments, for example, the most frequent operating conditions may also include the initial temperature that was most frequent during the first period for the combination of operating mode and operating course that was most frequently set during the first period. Here, the initial temperature is the temperature of the air inside the washing tub 15 at the start of the drying process. In this case, the operating data D1 includes the value detected by a temperature sensor located near the exhaust port of the drying path 111. The reason why the initial temperature may be included in the most frequent operating conditions is that the temperature of the air inside the washing tub 15 at the start of the drying process differs between the drying process performed after the dewatering process and the drying process when the drying course is repeated, and therefore the fluctuation of the current value of the fan motor 23 also differs.

[0139] In the embodiment described above, the maintenance requirement level is determined based on the attenuation rate. In other embodiments, the maintenance requirement level may be determined without relying on the attenuation rate. For example, in other embodiments, the maintenance requirement level may be determined by calculating a first current value and then determining the calculated first current value using a threshold value.

[0140] In other embodiments, the first server 3 may output maintenance information based on current values ​​for a predetermined number of operating cycles. For example, the predetermined number of operating cycles may be 10. In this other embodiment, for example, the server control unit 30 identifies operating data D1 under the same operating conditions for a predetermined number of operating cycles from the present, reads current value time series data from all of the identified operating data D1, and averages the current values ​​indicated by the read current value time series data. The server control unit 30 then determines the maintenance requirement level by performing a threshold check on the calculated average value and outputs maintenance information corresponding to the determined maintenance requirement level.

[0141] In other embodiments, the first server 3 may choose not to output maintenance information depending on the user P's place of residence or the place where the washing machine 1 was purchased. In this case, the record R includes the place of residence and the place of purchase as information, and the server control unit 30 outputs or does not output maintenance information depending on the place of residence and the place of purchase.

[0142] In another embodiment, if an error occurs in the washing machine 1 after using the maintenance service, the user P may be notified of information regarding free maintenance.

[0143] In other embodiments, the timing at which drying performance deteriorates due to lint adhesion may be predicted from the operating data D1, and the predicted timing may be notified to the user P.

[0144] In the embodiment described above, the first server 3 and the second server 5 were described as separate server devices, but these servers may be composed of the same server device. Furthermore, the first server 3 and the second server 5 may be composed of multiple server devices with different processing functions.

[0145] In the embodiments described above, the first server 3 is given as an example of the "output unit," and the terminal device 4 is given as an example of the "display unit." In other embodiments, the "display unit" may be the washing machine 1. In other embodiments, if the terminal device 4 can communicate directly or indirectly with the washing machine 1, the display of the terminal device 4, such as the touch panel 42, may be the "display unit." In other embodiments, the "output unit" and the "display unit" may be implemented as functions of the processor 120 of the washing machine 1 or the processor 400 of the terminal device 4. In these other embodiments, the "output unit" is a functional unit that outputs maintenance information and error information from the memory 130 of the washing machine 1 or the memory 410 of the terminal device 4.

[0146] In the embodiment 1 described above, a drum-type washer-dryer 1 was used as an example, but the washer-dryer 1 may also be a top-loading type.

[0147] In the above-described embodiment 1, a washing machine and dryer 1 was given as an example of a "clothing processing device." However, the "clothing processing device" is not limited to a washing machine and dryer 1, and may also be a dryer, or a device in which clothing is stored in a manner in which it is hung by hangers without the storage tub rotating, and the stored clothing is capable of being dried.

[0148] Processors 120, 300, and 400 may consist of a single processor or multiple processors. These processors may also be hardware programmed to implement the corresponding functional units. That is, these processors may consist of, for example, an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0152] (Note) Based on the above description of embodiments, the following technologies are disclosed.

[0153] (Technology 1) A maintenance notification system for a garment processing device comprising: a storage tank for storing clothes; a heat pump device for generating drying air and a blower fan for supplying the drying air; a drying path communicating with the storage tank; and a detection unit for detecting the current value of the fan motor of the blower fan, wherein the system further comprises: an output unit that outputs information based on the current value detected by the detection unit; and a display unit that displays information based on the information output by the output unit, wherein the output unit outputs maintenance information relating to the maintenance of the heat pump device based on the current value for a predetermined period or the current value for a predetermined number of operations; and the display unit displays the maintenance information. According to this, if the current value of the fan motor of the blower fan decreases, there is a possibility that lint clogging is occurring in the heat pump unit, and maintenance information will be displayed. Therefore, maintenance of the heat pump unit can be prompted, which can help prevent a decrease in the drying performance of the garment processing unit or restore its drying performance.

[0154] (Technology 2) A maintenance notification system for a garment processing device according to Technology 1, wherein the output unit compares a first current value relating to the current value during a first period which is a predetermined period with a second current value relating to the current value during a second period which includes a period earlier than the first period, and determines the maintenance information to be output based on the comparison between the first current value and the second current value. This allows for a comparison between the first current value and a second current value representing past current values, enabling the detection of a decrease in the fan motor's current value. Therefore, maintenance information can be determined based on the decrease in the fan motor's current value, prompting maintenance of the heat pump system. Consequently, this contributes to suppressing the decline in drying performance of the garment processing device or restoring its drying performance.

[0155] (Technology 3) The maintenance notification system for a garment processing device according to Technology 2, wherein the second current value is the current value during the period in which the second period is divided into multiple sections and the current value is the largest. This method allows for comparison of current values ​​over different periods while suppressing variations in current values, making it possible to detect decreases in the fan motor's current value. Therefore, it is possible to more effectively detect decreases in the fan motor's current value and prompt maintenance of the heat pump system.

[0156] (Technology 4) A maintenance notification system for a garment processing device according to Technology 2 or Technology 3, wherein the output unit causes the output maintenance information to differ based on a comparison of the first current value and the second current value.

[0157] This allows for the display of maintenance information corresponding to a decrease in the fan motor's current value. Therefore, it can prompt appropriate maintenance of the heat pump system.

[0158] (Technology 5) The maintenance notification system for a garment processing device according to Technology 4, wherein the output unit outputs different maintenance information based on the attenuation rate of the first current value relative to the second current value. This allows us to determine the degree of decrease in the fan motor's current value, and therefore, the maintenance information output can be varied according to the degree of decrease in the fan motor's current value. Consequently, maintenance information corresponding to the degree of decrease in the fan motor's current value can be displayed.

[0159] (Technology 6) The garment processing device maintenance notification system according to Technical Reference 5, wherein the display unit displays maintenance information prompting the user to perform maintenance on the garment processing device when the attenuation rate is below a predetermined value, and displays maintenance information recommending the use of a maintenance service for the garment processing device when the attenuation rate is greater than the predetermined value. According to this, if the attenuation rate is greater than the second threshold, it is recommended to use the garment processing equipment maintenance service and maintain the heat pump unit, thus preventing unnecessary recommendations for using the garment processing equipment maintenance service. Furthermore, if the attenuation rate is greater than the second threshold, it is highly likely that the reduced drying performance can be restored or the reduction in drying performance can be prevented by the user performing maintenance on the garment processing equipment, thus encouraging user maintenance.

[0160] (Technology 7) The first period is the most recent predetermined period based on the present, and the maintenance notification system for a garment processing device described in any one of the technologies 2 to 6. According to this, it is possible to detect a decrease in the current value of the most recent fan motor, and therefore the output maintenance information can be changed to correspond to the current value of the most recent fan motor.

[0161] (Technology 8) A maintenance notification system for a garment processing device according to any one of the technologies 1 to 7, wherein the output unit outputs error information relating to the error occurring in the garment processing device, prioritizing it over the maintenance information, and the display unit displays the error information. According to this, if an error occurs in the garment processing device, information about the error can be output, allowing the user to be advised to resolve the error.

[0162] (Technology 9) A maintenance notification system for a garment processing device according to any one of the technologies 1 to 8, comprising a terminal device capable of communicating directly or indirectly with the garment processing device, wherein the display unit is provided on the terminal device. According to this, outputting maintenance information via a terminal device increases the likelihood that users will notice the output of maintenance information. Therefore, it is possible to increase the likelihood that the heat pump system will be maintained. [Industrial applicability]
