Specifically, when the motor 40 outputs one of the driving forces, the rotating output shaft 41 of the motor 40 drives the clutch wheel to rotate in the direction B until each tooth curved surface of the sixth tooth pattern 531 is connected with each tooth surface of the second tooth pattern 5211. Tooth surfaces abut against each other. When the motor continues to rotate along the direction B, the second gear 521 will push the clutch wheel to move towards the first gear 511 through the curved surface of each tooth of its second tooth profile 5211 until the fifth tooth profile 532 of the clutch wheel and the first gear The first teeth 5111 of 511 mesh. When the clutch wheel continues to rotate along the direction B, it can drive the first gear 511 to rotate. Conversely, when the motor 40 outputs another motive force, the rotation output shaft 41 of the motor 40 drives the clutch wheel to rotate in the direction C until each tooth curved surface forming the fifth tooth pattern 532 is connected with each wheel of the first tooth pattern 5111. Tooth surfaces abut. When the motor 40 continues to rotate along the direction C, the first gear 511 will push the clutch wheel to move towards the second gear 521 through the curved surface of each tooth of its first tooth pattern 5111 until the sixth tooth pattern 531 of the clutch wheel is in contact with the second tooth pattern. The second teeth 5211 of the gear 521 are meshed. When the clutch wheel continues to rotate along the direction C, it can drive the second gear 521 to rotate.

Specifically, the refrigerator 500 may further include a control device and a control panel. The control device may be a main control board of the refrigerator 500 . The control panel can be arranged on the door body 200, and the control panel can at least include a plurality of buttons or knobs for controlling the operation of the quantitative dispensing device 100 and a button or knob for controlling the time. When the user needs to take the material quantitatively, the user can select the button or knob of the fixed material distribution device 100 corresponding to the material to be taken out, and select the button or knob of the outflow time of the material. The user only needs to place the material receiving cup on the corresponding quantitative distribution device. The bottom of the discharge port 31 of the device 100 is enough, the operation is convenient, the quantitative distribution is accurate, and the user experience is good.

Since the storage temperature of the refrigerator 500 is between 5°C and -18°C, the present invention can effectively solve the problem of rice and other grains and mildew by installing the quantitative dispensing device 100 on the door body 200 of the refrigerator 500, and at the same time Easy access for users.

Those skilled in the art should also understand that, unless otherwise specified, terms such as "up", "down", "inside" and "outside" in the embodiments of the present invention are used to indicate orientation or positional relationship. Based on the actual use status of the quantitative dispensing device 100 and the refrigerator 500, these terms are only for the convenience of describing and understanding the technical solution of the present invention, rather than indicating or implying that the referred device or component must have a specific orientation, Constructed and operative in a particular orientation and therefore are not to be construed as limitations of the invention.

So far, those skilled in the art should appreciate that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, without departing from the spirit and scope of the present invention, the disclosed embodiments of the present invention can still be used. Many other variations or modifications consistent with the principles of the invention are directly identified or derived from the content. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
