Abstract

A method for a household electrical appliance to perform mode switching includes detecting whether a user is in a sleeping state, switching a current operation mode to a silent mode if the user is in the sleeping state, and operating in the silent mode.

First claim

What is claimed is:

1. A method for a household electrical appliance to perform mode switching, wherein the household electrical appliance includes a fan, the method comprising:
detecting whether a user is in a sleeping state;
switching, if the user is in the sleeping state, a current operation mode to a silent mode; and
operating in the silent mode, including:
detecting a current air quality; and
adjusting a speed of the fan based on a sleep quality of the user and the current air quality, to cause the speed of the fan to be positively correlated with the sleep quality of the user, and to be negatively correlated with the current air quality, the adjusting comprising:
when the sleep quality of the user is a first sleep quality and the current air quality is a first air quality, adjusting the speed of the fan to a first speed;
when the sleep quality of the user is a second sleep quality and the current air quality is the first air quality, adjusting the speed of the fan to a second speed;
when the sleep quality of the user is the first sleep quality and the current air quality is a second air quality, adjusting the speed of the fan to a third speed;
when the sleep quality of the user is the second sleep quality and the current air quality is the second air quality, adjusting the speed of the fan to a fourth speed;
when the sleep quality of the user is the first sleep quality and the current air quality is a third air quality, adjusting the speed of the fan to a fifth speed; and
when the sleep quality of the user is the second sleep quality and the current air quality is the third air quality, adjusting the speed of the fan to a sixth speed,

wherein the first sleep quality is poorer than the second sleep quality, the first air quality is better than the second air quality, and the second air quality is better than the third air quality, the first speed is lower than the second speed, the second speed is lower than the third speed, the third speed is lower than the fourth speed, the fourth speed is lower than the fifth speed, and the fifth speed is lower than the sixth speed.

2. The method according to claim 1 , wherein detecting whether the user is in the sleeping state further comprises at least one of:
acquiring physiological data of the user and detecting whether the user is in the sleeping state based on the physiological data;
acquiring an operation state of a wireless access point and detecting whether the user is in the sleeping state based on the operation state of the wireless access point; or
acquiring a noise value of a current environment and detecting whether the user is in the sleeping state based on the noise value.

3. The method according to claim 2 , wherein operating in the silent mode includes:
detecting the sleep quality of the user based on the physiological data.

4. The method according to claim 1 , wherein:
the household electrical appliance includes a muffler, and
operating in the silent mode includes enabling the muffler.

5. A method for a controlling device coupled to a household electrical appliance to perform mode switching, wherein the household electrical appliance includes a fan, the method comprising:
detecting whether a user is in a sleeping state; and
sending, if the user is in the sleeping state, a mode switching instruction to the household electrical appliance to switch a current operation mode of the household electrical appliance, to cause the household electrical appliance operates in a silent mode, including:
detecting a current air quality; and
adjusting a speed of the fan based on a sleep quality of the user and the current air quality, to cause the speed of the fan to be positively correlated with the sleep quality of the user, and to be negatively correlated with the current air quality, the adjusting comprising:
when the sleep quality of the user is a first sleep quality and the current air quality is a first air quality, adjusting the speed of the fan to a first speed;
when the sleep quality of the user is a second sleep quality and the current air quality is the first air quality, adjusting the speed of the fan to a second speed;
when the sleep quality of the user is the first sleep quality and the current air quality is a second air quality, adjusting the speed of the fan to a third speed;
when the sleep quality of the user is the second sleep quality and the current air quality is the second air quality, adjusting the speed of the fan to a fourth speed;
when the sleep quality of the user is the first sleep quality and the current air quality is a third air quality, adjusting the speed of the fan to a fifth speed; and
when the sleep quality of the user is the second sleep quality and the current air quality is the third air quality, adjusting the speed of the fan to a sixth speed,

wherein the first sleep quality is poorer than the second sleep quality, the first air quality is better than the second air quality, and the second air quality is better than the third air quality, the first speed is lower than the second speed, the second speed is lower than the third speed, the third speed is lower than the fourth speed, the fourth speed is lower than the fifth speed, and the fifth speed is lower than the sixth speed.

6. The method according to claim 5 , wherein detecting whether the user is in the sleeping state further comprises at least one of:
acquiring physiological data of the user and detecting whether the user is in the sleeping state based on the physiological data;
acquiring an operation state of a wireless access point and detecting whether the user is in the sleeping state based on the operation state of the wireless access point; or
acquiring a noise value of a current environment and detecting whether the user is in the sleeping state based on the noise value.

7. The method according to claim 6 , further comprising:
detecting the sleep quality of the user based on the physiological data;
generating a speed adjusting instruction based on the sleep quality; and
sending the speed adjusting instruction to the household electrical appliance to adjust the speed of the fan based on the speed adjusting instruction.

8. The method according to claim 7 ,
wherein generating the speed adjusting instruction includes generating the speed adjusting instruction based on the sleep quality and the current air quality.

9. The method according to claim 5 , further comprising:
establishing a binding relationship with the household electrical appliance in advance.

10. A household electrical appliance device including a fan, comprising:
a processor; and
a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to:
detect whether a user is in a sleeping state;
switch, if the user is in the sleeping state, a current operation mode to a silent mode; and
operate the device in the silent mode, including:
detecting a current air quality; and
adjusting a speed of the fan based on a sleep quality of the user and the current air quality, to cause the speed of the fan to be positively correlated with the sleep quality of the user, and to be negatively correlated with the current air quality, the adjusting comprising:
when the sleep quality of the user is a first sleep quality and the current air quality is a first air quality, adjusting the speed of the fan to a first speed;
when the sleep quality of the user is a second sleep quality and the current air quality is the first air quality, adjusting the speed of the fan to a second speed;
when the sleep quality of the user is the first sleep quality and the current air quality is a second air quality, adjusti
