Fig. 1 is a configuration diagram of a refrigerator system of the present embodiment as an example of a home appliance system. Fig. 2 is a block diagram showing a configuration example of the refrigerator 1 of the present embodiment. Fig. 3 is a block diagram showing an example of the configuration of the server device 3 of the present embodiment. Fig. 4 is an external appearance front view of the refrigerator 1 of the present embodiment.
The refrigerator system has a refrigerator 1, a wide area network 2 such as the internet, a server apparatus 3 that receives information transmitted from the refrigerator 1 or stores refrigerator control software transmitted to the refrigerator 1, and a user terminal 4.
[ refrigerator 1]
The refrigerator has: a refrigeration cycle including a compressor for compressing a refrigerant and a cooler for generating cold air; a storage room such as a refrigerating room or a freezing room to which cold air generated by a cooler is supplied; a baffle plate which is arranged in an air path between the cooler and the storage chamber and can be opened and closed; a storage chamber door for opening and closing each storage chamber; a control panel (not shown) for receiving operations from a user such as temperature setting of each storage room; a defrosting unit such as a heater for defrosting frost attached to the cooler; the in-box lamp is installed in the storage room (not shown).
The refrigerator 1 includes a door opening/closing sensor 111 capable of detecting an open/close state of a storage room door, and turns on an in-box lamp of a storage room corresponding to each door when the door is opened, and turns off the in-box lamp when the door is closed.
The refrigerator 1 includes a CPU (Central Processing Unit) 101, a control program Unit 102, a memory 103, temperature sensors 104 for detecting the temperature in each storage compartment, electronic components 105 such as in-box lamps, a compressor 106, a pyroelectric sensor 107 for detecting a person on the front side of the refrigerator 1, an illuminance sensor 108 for detecting the brightness around the refrigerator 1, a communication Unit 109 for receiving and transmitting information via the wide area network 2, a door opening/closing sensor 111, a control panel display Unit 302 for displaying a response to an operation on the control panel, an LED112 for irradiating the control panel display Unit 302 to improve the visibility of display contents, a speaker 113 for outputting sound, and a control panel control Unit 114 for controlling the display contents of the control panel display Unit 302.
The refrigerator 1 uses the installed refrigerator control software 102 to control an input control unit that manages input of the sensors 104, 107, 108, and 111, an output control unit that controls the electronic component 105, the LED112, and the speaker 113, a compressor control unit that controls the compressor 106, a damper control unit that controls opening and closing of a damper disposed between the cooler and the storage room, a communication control unit that controls the communication unit 109, and a communication control unit that controls the panel control unit 114, respectively.
The refrigerator 1 can download new refrigerator control software from the server apparatus 3 via the wide area network 2 and the communication section 109 and store it in the memory 103.
The control program unit 102 controls the temperature of each storage room to be an appropriate temperature. The control panel display unit 302 displays the current setting content and the setting content changed by the user to the user via the LEDs 112. The control panel control section 114 can change the display content of the control panel display section 302 by receiving an operation of the control panel or an operation from the user terminal 4 received via communication.
[ Server device 3]
The server device 3 includes a reception control unit 201 that receives information from the refrigerator 1, a storage unit 202 that can store new control software for the refrigerator 1, a transmission control unit 203 that transmits the new control software to the refrigerator 1 or transmits a notification to the user terminal 4, and an arithmetic unit 204 that performs various calculations.
Fig. 5 is a control flowchart of embodiment 1. The refrigerator 1 cannot perform or has difficulty performing cooling of the storage chamber during execution of software update or defrosting control. Specifically, during execution of the software update, for example, control of the compressor control unit and the damper control unit cannot be executed or is difficult to execute. Further, since the temperature of the cooler rises during execution of the defrosting control, it is impossible or difficult to generate cold air, and it is difficult to cool the storage chamber during and immediately after the defrosting control. Therefore, if the software update is executed immediately after the defrosting control or at short time intervals, it is difficult to cope with the case where the time required for the update is longer than the predetermined time.
On the other hand, if the refresh is performed before defrosting, the temperature of the cooler increases due to the stop of cooling accompanying the refresh, and therefore the frost temperature (enthalpy of frost) increases. Therefore, the energy required for the defrosting operation can be reduced and the time required for defrosting can be easily shortened. Therefore, in the present embodiment, when there is control software to be updated, the defrosting control is executed after the update. In addition, software updating is executed in the process of avoiding defrosting or within 1 time after defrosting is finished. Specifically, for example, as described below, the next defrosting time Tk1 is first predetermined, and the reservation time Tk2 is set so as to be updated before defrosting. Further, it is preferable to increase the cooling of the storage room from a predetermined time before the update schedule time Tk 2.
After defrosting is completed (step S100), the refrigerator 1 of the present embodiment determines the next defrosting start time Tk1 (defrosting reservation section, step S101). The defrosting start time period can be estimated from the past operation history of the refrigeration cycle, or can be estimated by referring to the past interval of the defrosting operation and the elapsed time from the previous defrosting time.
In addition, a time zone with a low frequency of use by the user can be calculated and set as a time belonging to the time zone. As a method of calculating a time zone in which the frequency of use by the user is low, for example, the number of door opening/closing times per unit time can be collected and set as a time zone in which the number of door opening/closing times is low.
When storing new control software for the refrigerator 1 (yes at step S102), the server apparatus 3 transmits the control software to the refrigerator 1 or notifies the refrigerator 1 of the existence of the control software (step S103). Refrigerator 1 that has received the control software or the notification sets the time (scheduled time Tk2) at which the control software is updated (step S104). As a setting method of the reservation time, for example, it is set to 30 minutes before the next defrosting start time Tk1 determined at the defrosting end. If the reservation time is determined, the reservation time is notified from the refrigerator 1 to the server device 3. Tk2 may vary depending on the time required for updating the control software, but for example, the expected time required for updating may be acquired such that defrosting time Tk1 is within 30 minutes, 20 minutes, 10 minutes, or 5 minutes after the end of updating.
Next, the standby normal cooling operation is continued until the scheduled time Tk2 approaches (step S105, no, step S106). The term "approach" can be a time until the scheduled time Tk2, which can ensure a sufficient time for cooling of the storage compartment even if the storage compartment door of the refrigerator 1 continues to be opened and the storage compartment temperature rises, for example. It may be set to a suitable predetermined time (for example, one hour from the time Tk2) in a simple manner.
When reservation time Tk2 is close (yes at step S105), the cooling start/stop temperature of the storage room (preferably including the refrigerating room and the freezing room) is set to a lower temperature than normal (step S107), or the rapid cooling mode is set, and the power saving mode is released or temporarily released to cool down refrigerator 1. By changing the setting in this way, the temperature in the refrigerator can be set to a lower temperature before the start of updating the control software, and therefore, even if a cooling interruption accompanying the update occurs, the adverse effect on the food can be reduced.
Next, the user terminal 4 is notified that the reservation time Tk2 is close, for example, as illustrated in fig. 7 (step S108). The notification may include a message indicating that the scheduled end time of the refresh, the end time of the defrosting operation, and/or the estimated time of the cooling re-opening should be reduced before the scheduled end time of the defrosting operation, and the frequency of use (e.g., opening and closing of the door) of the refrigerator 1 should be suppressed.
When the scheduled time TK2 is reached (yes at step S109), the update of the control software is started (step S110). When the update of the control software is completed (yes in step S111), it is preferable to continuously (without actually cooling the cooler) start the defrosting operation of the cooler of the refrigerator 1 (step S112). At this time, if necessary, after the end of the update, control may be performed to advance the defrosting time Tk 1. Due to the interruption of cooling in the updating of the control software, the temperature of the cooler rises. Therefore, the defrosting operation can be executed after the update of the control software is completed, thereby shortening the defrosting time.
[ example 2 ]
Fig. 6 is a control flowchart of embodiment 2. The configuration of the present embodiment can be the same as embodiment 1 except for the following points. When storing new control software for the refrigerator 1 (step S202), the server apparatus 3 transmits the control software to the refrigerator 1 or notifies the refrigerator 1 of the existence of the control software (step S203). Then, in the present embodiment, the user terminal is notified of the updated control software, and the user can specify the update start time on the user terminal (step S204). The update start time that can be specified by the user can be specified, for example, in a time period of 12 to 24 hours before the defrosting start time Tk1 as shown in fig. 8. That is, in the present embodiment, the defrosting time Tk1 is determined by the refrigerator 1, and a certain time width before the defrosting time is presented to the user. It is specified that, regardless of the timing at which the update is started, the respective storage chambers can be sufficiently cooled before defrosting at Tk1 as exemplified in embodiment 1. This is because if the user freely sets the update start time, the defrosting time needs to be adjusted in accordance with the update start time, and the complexity of cycle control increases. The server apparatus 3 is notified of the update start time after the update start time is determined (step S205).
