Technical Field

[0001] The present invention belongs to the technical field of refrigerator control, and in particular relates to a voice control method for a Wi-Fi refrigerator. Background Art

[0002] Most refrigerators on the market are online voice refrigerators that include a wake-up function. False wake-ups will disturb users. Considering that refrigerator interaction is more about the refrigerator conveying information to users and the number of user controls is relatively small, the high-cost online voice + wake-up function is not suitable.

[0003] Patent publication number CN108199938A discloses a voice-controlled smart speaker equipped with a voice receiving unit, a Wi-Fi connection device, an infrared transceiver, and a main control unit. The Wi-Fi connection device is bidirectionally connected to home appliances Wi, and the infrared transceiver is bidirectionally connected to home appliances Hj. The infrared transceiver transmits signals in a 360-degree angle. Home appliances Wi are televisions, refrigerators, air conditioners, microwave ovens, or rice cookers; home appliances Wj are televisions, refrigerators, air conditioners, microwave ovens, or rice cookers. The voice receiving unit is equipped with a wake-up word judgment unit that wakes up the voice reception after the wake-up word appears. This voice-controlled smart speaker can control the operation of other connected appliances in the home through voice, and is highly intelligent and easy to operate.

[0004] The above patent still uses the high-cost online voice + wake-up function, which is relatively expensive. This application, while ensuring voice interaction, optimizes the voice broadcast logic and scenarios, removes the wake-up function, reduces costs, and ensures the rationality of the refrigerator broadcast, ensuring a good user experience. Summary of the Invention

[0005] The purpose of the present invention is to provide a voice control method for a Wi-Fi refrigerator, which solves cost control and broadcasting problems by optimizing voice broadcast logic and scenarios and removing the wake-up function.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0031] See also Figure 1 As shown, the present invention is a voice control method for a Wi-Fi refrigerator, comprising the following steps:

[0032] S101: The refrigerator is powered on, the voice module is activated, and a voice reminder is given;

[0033] S102, the controller detects whether the WiFi module is connected to the Internet. If so, the default do not disturb time is turned on. When there is language material to be broadcasted, it is determined whether it is a reminder for not closing the door;

[0034] S103, if the door is not closed, a voice reminder is given to close the refrigerator door;

[0035] S104, if it is not a door closing reminder, determine whether the time is a do not disturb time, the do not disturb time is from 21:00 to 7:00; the do not disturb time can be set through the controller;

[0036] S105: If it is during the do not disturb time, no voice announcement will be made, and the announcement will be made when the user opens the door later;

[0037] S106, if it is not during the do not disturb time, real-time operation will be broadcast in real time, and non-real-time operation will be reminded after the door is opened; among them, real-time operation includes temperature and mode adjustment operation; non-real-time operation includes fault reminder and service and function guidance;

[0038] S107, if WiFi is not connected, real-time operation is performed in real time, and non-real-time operation is performed in the form of door opening broadcast without time judgment.

[0039] The broadcast scenes are divided into several categories: power-on reminder - broadcast as soon as the power is turned on; real-time operation - real-time voice reminder; fault reminder - reminder when the door is opened when there is a fault; service and function guidance - occasional door opening reminder, with an extended reminder cycle; door not closed reminder - reminder after three minutes if the door is not closed; service and function guidance operation is to sequence the scene entries of service reminders and function guidance, and play one every several days. If it is restricted by other entries with higher priority or do not disturb during playback, the entry will be played after a few days.

[0040] like Figure 2 As shown, a voice control system for a Wi-Fi refrigerator includes a controller, a voice chip and a WiFi communication module. The controller is used to control the operation of the refrigerator; the controller is connected to a cloud server through the WiFi communication module to exchange information; the cloud server exchanges information with a terminal device, and the terminal device transmits control instructions to the controller through the cloud server; the terminal device can be a mobile phone or a tablet computer. For example, the user can set a do not disturb period through the APP and mini-program in the mobile phone; if the broadcast happens to occur during the do not disturb period, no reminder will be given at this time.

[0041] The controller is connected to the switch detection module, the clock module and the control panel. The control panel transmits control instructions to the controller, and the clock module is used to provide a standard clock signal to the controller. The switch detection module detects the switch status of the refrigerator door. The controller is also connected to a storage module, which is used to store the voice broadcast vocabulary and the control parameter data of the refrigerator. The controller controls the speaker operation through the voice chip to perform voice broadcast.

[0042] The control instructions transmitted by the control panel to the controller include time setting instructions, temperature setting instructions and control mode setting instructions. After receiving the control instructions, the controller controls the refrigerator to operate according to the control instructions and broadcasts the instructions through the voice chip. The switch detection module is used to detect the switch status of the refrigerator door. When the controller detects that the refrigerator door is open for a long time, the controller controls the voice chip to broadcast a reminder that the door is not closed. For example, if the door is not closed for more than 3 minutes, the controller will broadcast a reminder that the door is not closed.

[0043] The controller is also connected to the buzzer. When the controller turns off the speaker, the buzzer is turned on to give a buzzer reminder. When the voice function is turned off, the buzzer gives a reminder and operates according to the rules of a conventional refrigerator. When the voice function is turned on, the buzzer does not sound.
