The sensing device 40 in the water supply device 20 can be detected by providing the detecting device 30 also in the door body and above the water supply device.

In this embodiment, the water supply device 20 can store water inside, and the water supply device 20 can provide cool water to a user when placed in a refrigerator. The water supply device 20 may be provided on a support frame inside the door body 10. The detection device 30 is also provided in the refrigerator above the water supply device 20, and is capable of detecting the sensing device 40 in the water supply device 20. The sensing means 40 can be detected by the detecting means 30 when the water level in the water supply means 20 is lowered, so that the insufficient amount of water in the water supply means 20 can be indicated when the sensing means 40 is detected by the detecting means 30, and it can be determined that the water supply means 20 is placed inside the door body 10.

Referring to fig. 2 and 3, in some embodiments, the sensing device 40 includes a driving member 410, a float assembly 430, and a sensing part 440, the driving member 410 is disposed inside the water supply device 20, the driving member 410 includes a first end and a second end, and a rotation shaft 420 disposed between the first end and the second end, the rotation shaft 420 is connected to the water supply device 20, and the driving member 410 is configured to be rotatable about the rotation shaft 420; the float assembly 430 is provided at a first end, and is configured to rise or fall following a water level change within the water supply device 20; the sensing component 440 is disposed at the second end, and is detected by the detecting device 30 when approaching the detecting device 30; when the water level in the water supply device 20 drops, the float assembly 430 drives the first end to drop, the driving member 410 rotates around the rotation shaft 420 and drives the sensing member 440 at the second end to rise, so that the sensing member 440 approaches the detecting device 30.

When the sensing means 440 is detected by the detecting means 30, it can be determined that the water supply device 20 is placed in the door body 10 and the water supply device 20 is deficient in water. When the water level in the water supply device 20 rises, the float assembly 430 rises, the sensing member 440 is driven to descend by the driving member 410, the sensing member 440 is far away from the sensing device 30, and when the sensing member 440 is separated from the bottom sidewall of the cover 220, the sensing member 440 cannot be detected by the sensing device 30, and it can be determined that the water level has reached the maximum water level in the water supply device 20.

Specifically, the mounting portion 450 may strike the bottom side wall of the cover 220 after rising, and during the use of the water supply device 20, the mounting portion 450 will strike the bottom side wall of the cover 220 continuously, and by providing the base 4501 and the accommodating portion 4502, the mechanical strength of the mounting portion 450 can be enhanced, so that the mounting portion 450 is not easy to be deformed by striking, and the service life of the sensing device 40 is prolonged.
