The washing machine communication system via these communication networks is configured to cope with the following situations, for example.

  For example, in the case of a washing / drying machine, the laundry is washed or dried according to the operation control program stored in the memory of the washing / drying machine itself. The operation control program is selected from a plurality of courses according to the needs of the user, and is changed according to the situation. Washing from a plurality of courses and course changes are performed by the user directly operating the operation switches of the washing and drying machine. The laundry system disclosed in Patent Documents 1 and 2 includes a laundry device, a home terminal, and external data providing means (database). The laundry machine includes home terminal communication means in addition to operation control means for washing or drying laundry according to the operation control program. In addition to the display means, the input means, the control unit, etc., the home terminal has a communication means for laundry for communicating with the laundry equipment, and an external communication means for communicating with the external data providing means. The control unit of the home terminal displays the item to be washed on the display unit, and when the item to be washed is selected by the input unit, the control data such as operation control data and various data according to the selected item to be washed is Obtained from external data providing means and transferred to laundry equipment.

  According to this laundry system, by selecting a target item of the washing machine from the home terminal, operation control information corresponding to the item can be taken in by the home terminal, and the control data can be held in the laundry device when necessary.

  Moreover, the user needs to maintain regularly the filter which collects foreign materials, such as lint generated from the laundry. However, when the user tries to clean the filter, the user does not know how to care for it, and sometimes the maintenance itself is delayed. The washing machine body has a simple description of filter cleaning, and the user had to look at it and take care of it, or if he wanted to know more details, he had to take out the instruction manual and check it.

  As a way to improve this workability, various guidance information and abnormal information detected by sensors are displayed on the operation display panel of the washing machine, and if necessary, good operability is provided by voice and hearing. What is known is also known (see, for example, Patent Document 3).

  In the second embodiment, the server 300 includes storage means for storing the number of times of driving, the number of times of driving threshold, and the like. Other configurations use the configuration of the first embodiment. Hereinafter, a different part from Embodiment 1 is demonstrated.

  The portable terminal 10 includes a first communication unit 101 (wireless communication unit), a second communication unit 102, a display unit 103 (terminal display unit), an operation unit 104 (portable terminal), a control unit 105 (terminal control unit), and a loop antenna. 106.

  The server 300 includes a communication unit 301, a storage unit 302, and a control unit 303. The communication unit 301 communicates with the mobile terminal 10 using the network 200.

  The storage unit 302 stores information on the menu screen displayed on the mobile terminal 10 for each product of the washing machine 1. The storage unit 302 includes an operation frequency threshold storage unit 302a, an operation frequency storage unit 302b, and a difference calculation result storage unit 302c.

  The number-of-operations threshold storage unit 302a stores a threshold value of the number of times of washing operation and drying operation for displaying maintenance information. The operation number storage means 302b stores the number of washing operations and the number of drying operations. The difference calculation result storage means 302c stores a subtraction result between the number of washing and drying operations when the previous maintenance guide is displayed and the number of operations when this time is displayed.

  The control unit 303 is configured by a CPU or the like, controls the operation of the communication unit 301, and communicates with the mobile terminal 10 based on the information received via the communication unit 301 and the information stored in the storage unit 302. To generate information to be transmitted. Further, the control means 303 includes an operation frequency difference calculation unit 303a and a threshold comparison calculation unit 303b. The number-of-operations difference calculation unit 303a calculates the difference between the number of washing operations or the number of drying operations between certain time points. Specifically, the number of times of washing operation and drying operation of the washing machine 1 when the maintenance information is displayed on the portable terminal 10 last time, and the number of times of washing operation and drying operation when the portable terminal 10 and the washing machine 1 communicate with each other. The difference between is calculated. The difference calculation result storage unit 302c calculates the calculation result of the operation number difference calculation unit 303a. The threshold comparison operation unit 303b compares the information stored in the driving frequency threshold storage unit 302a with the information stored in the difference calculation result storage unit 302c. The control unit 303 sends an instruction to display maintenance guidance on the portable terminal 10 through the communication unit 301 according to the result of comparison by the threshold comparison operation unit 303b.

  Hereinafter, the step of displaying the maintenance guidance will be described with reference to FIG.

  The flow from starting the application to receiving the washing machine specifying information is the same as that in FIG. 4 of the first embodiment.

  In step S1501, the mobile terminal 10 transmits the washing machine specifying information and the number of washing / drying operations to the server.

  In step S1511, server 300 receives the washing machine specifying information and the number of times of washing / drying operation. The received operation count is stored in the operation count storage means 302b. The operation number difference calculation unit 303a calculates the difference between the operation number stored in the operation number storage unit 302b and the operation number when the previous maintenance information is displayed. The difference calculation result storage unit 302c stores the result of the operation number difference calculation unit 303a. In step S1512, the threshold comparison calculation unit 303b compares the value stored in the difference calculation result storage unit 302c with the value stored in the number-of-operations threshold storage unit 302a. If the operation frequency difference is smaller than the threshold value (YES in step S1512), menu screen information is created in step S1513. If the operation frequency difference is larger than the threshold (NO in step S1512), maintenance screen information is created in step S1515. Thereafter, menu screen information is created in step S1513. Thereafter, the server 300 transmits the creation information in step S1514.

  The portable terminal 10 receives the menu screen information in step S1502, and displays the menu screen based on the information received by the display unit 103 in step S1503. That is, if the number of operations does not exceed the threshold value, a normal menu screen is displayed. If the number of driving times exceeds the threshold value, in addition to the normal menu screen, for example, a display for prompting maintenance as shown in FIG. 16 is displayed as a pop-up.
