When the dust collecting device 2 is installed in the installation cavity 14, the sensing member 17 can sense the magnetic member 24, thereby judging that the dust collecting device 2 is installed in place. When the sensing member 17 does not sense the magnetic member 24, it is judged that the dust collecting device 2 is not installed or the dust collecting device 2 is not installed in place, and the rice washing device is controlled to stop working, and a warning that the dust collecting device 2 is not installed in place can be issued to remind the user. Thereby ensuring that the rice washing device can start working only when the dust collecting device 2 is installed in place, and improving the safety and reliability of the use of the rice washing device.

[0060] Among them, the sensing member 17 can be a Hall element or a reed switch. When the sensing member 17 is a Hall element, since the magnetic member 24 is close to the Hall element, the Hall element can detect a pulse signal. Therefore, it is possible to determine whether the dust collecting device 2 is installed in place based on whether the Hall element detects a pulse signal. When the sensing member 17 is a reed switch, since the magnetic member 24 is close to the reed switch, the two magnetic reeds in the reed switch will be in contact and conductive. Therefore, it is possible to determine whether the dust collecting device 2 is installed in place based on whether the reed switch is conductive.

[0061] In the illustrated embodiment, the magnetic member 24 is disposed on the handle 2213, so that it can simultaneously detect whether the dust collecting device 2 is installed in place and whether the first filter element 221 is installed in place, thereby preventing the user from missing the first filter element 221. Of course, in other embodiments, the magnetic member 24 can also be disposed on the outer surface of the dust collecting box 21 facing the sensing member 17, as long as it is ensured that when the dust collecting device 2 is installed in place, the sensing member 17 can accurately sense the magnetic member 24, and the embodiment of the utility model is not specifically limited here.

[0062] like Figure 1 As shown, the embodiment of the utility model also provides an electric rice cooker, comprising a main body 4, a cooking device 5 and the above-mentioned rice washing device, wherein the cooking device 5 and the rice washing device are both arranged in the main body 4, and the rice washing device is located above the cooking device 5, and the rice washing device can drop the washed rice into the cooking device 5. The electric rice cooker can be a desktop electric rice cooker or a built-in electric rice cooker as shown in the figure.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
