As shown in fig. 1 and 2, a refrigerator according to an embodiment of the present invention may generally include a cabinet 10, a

door

20, 30, 40, and an illumination apparatus 400.

The cabinet 10 defines a storage compartment for storing items to be refrigerated/frozen. The number of the storage compartments is one or more. In the embodiment shown in fig. 1-2, the housing 10 defines 3 storage compartments 11, 12, 13. The door body is used for opening or closing the storage compartment. For embodiments in which a plurality of storage compartments 11, 12, 13 are provided, each

storage compartment

11, 12, 13 is associated with a respective one or

more door bodies

20, 30, 40. The

door bodies

20, 30, and 40 include a door body that is opened and closed by rotation, a door body that translates left and right, and a drawer door that is pushed and pulled back and forth. The lighting device 400 is disposed in the storage compartment. At least one lighting device 400 can be matched in each storage chamber to be used for lighting the storage chambers, so that a user can conveniently take and place food.

The refrigerator as a whole can be refrigerated by a vapor compression refrigeration cycle system, which defines a cooling chamber in which an evaporator is disposed for cooling air. And cold air is transmitted to each storage chamber by using the air duct so as to refrigerate each storage chamber.

According to different refrigerating temperatures, each storage compartment in the refrigerator can be divided into different compartments such as a refrigerating compartment, a freezing compartment and a temperature changing compartment. For example, the temperature in the refrigerated compartment is generally controlled between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature range in the freezer compartment is typically controlled between-22 ℃ and-14 ℃. The temperature-changing chamber can be adjusted between-18 ℃ and 8 ℃ to realize the temperature-changing effect. The optimal storage temperatures of different kinds of articles are different, and the storage compartments suitable for storage are also different. For example, fruit and vegetable foods are suitably stored in the refrigerating compartment, while meat foods are suitably stored in the freezing compartment.

The refrigerator according to the embodiment of the present invention performs dual control of the lighting device 400 through the conventional control module 200 and the voice control module 300. Under the normal use condition, the lighting device 400 is controlled to be turned on once the door body is opened, and the lighting device 400 is controlled to be turned off when the opening time reaches a first preset time or the door body is turned off. Under the special circumstances, if the door body opens for a long time and leads to lighting device 400 closed the back, the user still can open again through acoustic control mode control lighting device 400, need not to close the door again, the operation of opening the door, has satisfied the user to the long-time demand of throwing light on of storing room, and user experience is better. In addition, the lighting device 400 is controlled in a voice control mode, and compared with a common voice control mode, the voice control mode is easier to learn, simpler and more practical.

In some embodiments, it is preferable that the second preset duration is greater than the first preset duration. Namely, after the lighting device is turned on for the first preset time, the door body is not closed, and the lighting is hopefully continued to be obtained, so that the lighting time is prolonged in a voice control mode. Therefore, at least the extended time (the second preset time) should be longer than the previous lighting time (the first preset time) to avoid the situation that the extended lighting time is still insufficient and the user needs to sound again to wake up the lighting, so as to improve the user experience.

door

20, 30, 40 is closed and receives a sound with a strength greater than a preset strength. Thus, even under dark environment, the user can light the display screen 500 through sound, thereby accurately finding the refrigerator position without additionally turning on an indoor illumination lamp.

As shown in fig. 5, the power supply line of the voice control module 300 to the display screen 500 is provided with a switch 310. The voice control module 300 is configured to: when the

door

20, 30, 40 is closed, the power supply line is put into an on state, and when the

door

20, 30, 40 is opened, the corresponding switch is switched to an off state.

In some embodiments, the voice control module 300 is configured to control the display 500 to stop lighting after controlling the display 500 to light for a third preset duration. Alternatively, the voice control module 300 is configured to control the display 500 to stop emitting light when receiving the sound with the intensity greater than the preset intensity again after controlling the display 500 to emit light. Alternatively, the voice control module 300 is configured to control the display screen 500 to stop emitting light when the

door bodies

20, 30, 40 are opened. One or more of the above-described three light-off conditions may be optionally used. If the configuration is various, when a condition is met, the display screen 500 is controlled to stop emitting light, so that the electric energy waste caused by long-time lighting of the display screen 500 is avoided.

In some embodiments, the voice control module 300 is disposed on the top of the front surface of the door body 20 positioned highest so as to be closer to the head height of a normal adult to better receive sound waves emitted from a human body.
