[0028] The following is combined Figures 1-5 This invention describes a refrigerator with a weighing function provided in an embodiment of the present invention.

[0029] like Figure 1 and Figure 2 As shown, in an embodiment of this utility model, the refrigerator with weighing function includes: a refrigerator body 100, a container 10, and a weight sensor 30. The refrigerator body 100 has a refrigerator compartment, and the weight sensor 30 is disposed on the bottom surface of the refrigerator compartment and connected to a coffee machine. The container 10 is used to store dairy products, and the container 10 is disposed on the weight sensor 30. The weight sensor 30 is used to detect the weight of the container 10 to detect the amount of dairy products in the container 10.

[0030] Specifically, in this embodiment, the refrigerator body 100 may have only a refrigerator compartment, or it may have both a refrigerator compartment and a freezer compartment. A weight sensor 30 is installed on the bottom surface of the refrigerator compartment. When a container 10 containing dairy products is placed on the weight sensor 30, the weight sensor 30 can detect the weight of the container 10. This weight includes the weight of the container 10 itself and the weight of the dairy products. Subtracting the weight of the container 10 itself from this weight gives the weight of the dairy products in the container 10. The weight sensor 30 transmits the detected data to the coffee machine. When the amount of dairy products in the container 10 meets the user's needs, the coffee machine will suck up the dairy products from the container 10. When the amount of dairy products in the container 10 does not meet the user's needs, the coffee machine will stop sucking up the dairy products and issue an alarm to remind the user to add dairy products in time.

[0031] Optionally, in an embodiment of this utility model, the number of weight sensors 30 can be one or more. When there is only one weight sensor 30, it can be set at the center of the bottom surface of the refrigerator compartment. When the container 10 is placed on it, the weight sensor 30 is located at the center of the container 10 to accurately detect the weight of the container 10. When there are multiple weight sensors 30, they can be arranged in a ring. When the container 10 is placed on it, multiple weight sensors 30 can detect the weight of the container 10 at the same time to improve the accuracy of detection.

[0032] Optionally, in an embodiment of this invention, the weight sensor 30 can be wirelessly connected to the coffee machine or connected via a wire.

[0033] The refrigerator with weighing function provided in this embodiment of the utility model can monitor the amount of dairy products in the container in real time by setting a weight sensor inside the refrigerator, ensuring the content of dairy products in the beverage, avoiding the situation where the dairy product content in milk coffee is insufficient, and improving the user experience.

[0034] like Figure 2As shown, in an embodiment of this utility model, the refrigerator with weighing function further includes a weighing pan 20, which is disposed on the weight sensor 30 and is used to hold the container 10. In this embodiment, the weighing pan 20 includes a base plate and an edge surrounding the base plate to form a pan-shaped structure. In this embodiment, the size of the weighing pan 20 is slightly larger than the size of the container 10 so that the weighing pan 20 is subjected to uniform force after the container 10 is placed on it, thereby ensuring the accuracy of the data detected by the weight sensor 30.

[0035] Optionally, in one embodiment of the present invention, the center of the weight sensor 30 is located on the same straight line as the center of the weighing pan 20, that is, the weight sensor 30 is disposed at the center of the weighing pan 20 so that the center of gravity of the container 10 is collinear with the center of gravity of the weight sensor 30, thereby accurately weighing the weight of the container 10.

[0036] Optionally, in another embodiment of this utility model, there are multiple weight sensors 30, which are arranged in a ring on the bottom surface of the refrigerator compartment. Arranging multiple weight sensors 30 in a ring provides uniform support to the weighing pan 20. When the container 10 is placed on the weighing pan 20, the multiple weight sensors 30 can simultaneously acquire the weight of the container 10, thereby improving the accuracy of the detection.

[0037] like Figure 3 As shown, in an embodiment of this utility model, the weight sensor 30 includes a pressure block 31, a measuring circuit 32, and a wire 40. The pressure block 31 is disposed on the bottom surface of the refrigerator compartment, and the center of the pressure block 31 is aligned with the center of the weighing pan 20. The measuring circuit 32 is also disposed on the bottom surface of the refrigerator compartment and is electrically connected to the pressure block 31. The first end of the wire 40 is connected to the measuring circuit 32, and the second end of the wire 40 is used to connect to a coffee machine.

[0038] Specifically, the pressure block 31 has a strain gauge. When the container 10 is placed on the pressure block 31, the strain gauge deforms and its resistance changes. The measuring circuit 32 converts the resistance change into a voltage signal, and converts, amplifies and processes the voltage signal to finally obtain the weight value. The weight value is then transmitted to the coffee machine through the wire 40.

[0039] like Figure 3 As shown, in an embodiment of this utility model, the refrigerator with weighing function further includes a fixing block 50, which is disposed on the bottom surface of the refrigerator compartment. The pressure-bearing block 31 and the measuring circuit 32 are both disposed on the fixing block 50. In this embodiment, the fixing block 50 can be a block structure, and the fixing block 50 is connected to the bottom surface of the refrigerator compartment. The pressure-bearing block 31 and the measuring circuit 32 are disposed on the fixing block 50.

[0040] like Figure 4As shown, in this embodiment of the present invention, the fixing block 50 is provided with a U-shaped groove 51, and the pressure-bearing block 31 is provided with a pair of first protrusions 311 on the side facing the fixing block 50. The pair of first protrusions 311 are arranged in parallel and embedded in the U-shaped groove to limit the pressure-bearing block 31 to the fixing block 50. In this embodiment, the pressure-bearing block 31 is connected to the fixing block 50 by bolts.

[0041] Furthermore, such as Figure 5 As shown, the pressure-bearing block 31 has a pair of second protrusions 312 on the side opposite to the fixing block 50. The pair of second protrusions 312 are arranged in parallel, and when the container 10 is placed on the pressure-bearing block 31, the second protrusions 312 abut against the container 10. In this embodiment, strain gauges can be disposed on the second protrusions 312 to contact the container 10. In this embodiment of the present invention, the second protrusions 312 are arranged perpendicularly to the first protrusions 311 to enhance the strength of the pressure-bearing block 31.

[0042] like Figure 4 As shown, in this embodiment of the present invention, the refrigerator with weighing function further includes a mounting plate 60. The mounting plate 60 includes a receiving portion and a pair of connecting portions 63. The receiving portion has a box-like structure, including a bottom plate 61 and multiple side plates 62 surrounding the bottom plate 61. The open side of the box-like structure faces the bottom surface of the refrigerator compartment, thus forming a cavity between the bottom surface of the refrigerator compartment and the bottom plate 61 of the box-like structure. A fixing block 50 is disposed on the bottom plate 61, which has a through hole 611. The side plate 62 facing the back of the refrigerator body 100 has a notch 621. The wire 40 extends to the outside of the refrigerator body 100 through the through hole 611 and the notch 621. A pair of connecting portions 63 are disposed opposite each other on both sides of the box-like structure and connected to the side plates 62. In this embodiment, the pair of connecting portions 63 are also connected to the bottom surface of the refrigerator compartment, thereby fixing the mounting plate 60 inside the refrigerator compartment. It should be noted that in this embodiment, the surface facing the refrigerator door is the back of the refrigerator body 100.

[0043] like Figure 4 As shown, in an embodiment of this utility model, the base plate 61 is provided with a through groove 612 extending through its thickness direction. A portion of the fixing block 50 is located above the through groove 612, and the second boss 312 of the pressure block 31 extends to the bottom of the through groove 612 and is located in the cavity formed by the base plate 61 and the bottom surface of the refrigerator compartment. The bolt that connects the pressure block 31 and the fixing block 50 is located in the cavity.
