Embodiment 1

[0017] This embodiment proposes a weighing device for a refrigerator, such as figure 1 , figure 2 As shown, it includes a bottom bracket 11, a gravity sensor, an upper bracket 13, and a weighing pan 14 arranged sequentially from bottom to top. According to the material of the storage compartment and the pressure, the upper bracket 13 is located at the center of the weighing pan 14. The length accounts for 1 / 3-2 / 3 of the length of the weighing pan 14, and the width accounts for 1 / 3-2 / 3 of the width of the weighing pan 14. The gravity sensor is fixed on the bottom bracket 11, and the gravity sensor is fixed to the weighing pan 14 through the upper bracket 13 . The weighing principle of this weighing device is that when there is a heavy object on the weighing pan, the gravity of the heavy object is transmitted through the upper bracket and concentrated at the gravity sensor. The gravity sensor converts the mechanical quantity into an output voltage and changes. After the circu...

Embodiment 2

[0032] This embodiment proposes a weighing drawer, such as figure 1 As shown, it includes a drawer body 30, and also includes a weighing device as described in Embodiment 1. The weighing device is fixed in the drawer body 30 through its bottom bracket 11. For the specific structure of the weighing device, see Figure 1-Figure 5 and described in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a weighing device for a refrigerator. The weighing device comprises a bottom bracket, a gravity sensor, an upper bracket and a weighing scale which are sequentially arranged from bottom to top. The gravity sensor is fixed to the bottom bracket and is fixed to the weighing scale through the upper bracket. The upper bracket is located in the center of the weighing scale. The length of the upper bracket is equal to 1 / 3-2 / 3 of the length of the weighing scale, and the width of the upper bracket is equal to 1 / 3-2 / 3 of the width of the weighing scale. The invention further discloses a weighing drawer comprising the weighing device. According to the weighing device for the refrigerator, by arranging the upper bracket, the force moment borne by the weighing scale is reduced, deformation of the weighing scale is reduced, and accordingly the contact probability of the weighing scale and other structures is reduced; and the problem that weighing is inaccurate due to the fact that the weighing scale makes contact with the other structures is solved, and the weighing precision is high.

Description

technical field [0001] The invention relates to a weighing device and a weighing drawer for a refrigerator. Background technique [0002] As the user's demand for refrigerator functions becomes more and more refined, if the weight information of the food stored in the refrigerator can be obtained regularly, and the remaining food can be judged based on the weight information, so that the user can be reminded in time to purchase supplements. demand, the current weighing principle of refrigerators with food weight sensing function is: by setting a load cell under the storage compartment, the load cell supports the storage compartment through the weighing pan, and when items are placed in the storage compartment, the resistance strain of the load cell When the sheet is deformed, the resistance value of the resistance strain sheet will change accordingly, and then the voltage output by the gravity sensor will change. After the voltage is processed by the signal processing circui...
