Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment one
The present embodiment proposes a kind of weighing device for refrigerator, as shown in Figure 1 and Figure 2, including sets successively from bottom to top
Bottom bracket 11, gravity sensor, upper bracket 13 and the scale pan 14 set according to matter storage lattice material and bear pressure not
Together, upper bracket 13 is located at the center of the scale pan 14, and length accounts for the 1/3-2/3 of 14 length of the scale pan, and it is wide that width accounts for the scale pan 14
The 1/3-2/3 of degree, gravity sensor are fixed on bottom bracket 11, and gravity sensor is solid by upper bracket 13 and the scale pan 14
It is fixed.The weighing principle of this weighing device is, when having weight on the scale pan, the gravity of weight concentrates on gravity by upper bracket transmission
At sensor, the voltage that mechanical quantity is transformed into output by gravity sensor changes, the voltage by signal processing circuit at
After reason, the weight information of food is exported by control chip, by the way that upper bracket is arranged, reduces the torque that the scale pan is born, the scale pan
The deformation of generation can become smaller, and to reduce the probability of scale pan other structures contact, solve since the scale pan and other structures connect
The problem for inaccuracy of weighing caused by touching.
Specifically, as shown in Fig. 2, gravity sensor includes sensor body 12, sensor body 12 be equipped with it is upper
The first connecting portion 15 that portion's holder 12 connects and the second connecting portion 16 that is connect with bottom bracket 11, first connecting portion 15 and the
Two interconnecting pieces 16 are located at the both sides of sensor body 12 along its length, and gravity sensor further includes first resistor foil gauge
With second resistance foil gauge（It is not shown in figure）, first resistor foil gauge and second resistance foil gauge are respectively oppositely set to biography
On the upper surface and lower face of sensor ontology 12, and the position between first connecting portion 15 and second connecting portion 16, it is above-mentioned
First connecting portion 15 and second connecting portion 16 are arranged at the diagonal position of sensor body 12 gravity sensor, are conducive to make
It obtains resistance strain gage and generates deformation, improve weighing precision.
As shown in figure 3, the portions P of such as scale pan 14 are placed with weight（This position is typically to be easiest to make the scale pan 14 in Fig. 1
Generate the position of deformation）, the gravity of the weight is F, if if upper bracket 13 is not arranged, the arm of force that the scale pan is born is L, namely
Distance of the stress point at resistance strain gage position, the torque that the corresponding scale pan is born are M=FL, are arranged after upper bracket 13, first
The gravity of first weight is applied in upper bracket 13, is then applied to resistance strain gage position, Ye Jili by upper bracket 13
Arm is reduced to L-L ', and the torque that the corresponding scale pan 14 is born is reduced to M '=FL-FL ', and the deformation that the scale pan 14 generates can become smaller, to
The probability that the other structures such as the scale pan and bottom shelf contact is reduced, is solved since the scale pan 14 is contacted with other structures and is caused
Inaccurate problem of weighing.
The length direction of sensor body 12 is provided with horizontal a pair of parallel hole, for reducing 12 rigidity of sensor body,
Increase deflection when weighing.
This weighing device is particularly suitable in the equipment such as refrigerator, and since ambient humidity is big in refrigerator, the scale pan is often using tool
There is antiseptic property and material is light, plastic material easy to process makes, however is poor rigidity the shortcomings that plastic material, by
It is easily deformed when to pressure, and due to being limited by interior refrigerator space, in order to provide the user with maximum use space,
Need each structure all to design it is compacter, therefore, between the scale pan and surrounding other structures（Such as shelf, neighbouring matter storage lattice）
Other structures, therefore scale pan deformation and other knots are not touched when it is not possible that there are enough distances to prevent the scale pan from deforming
Structure touches and then causes inaccurate problem of weighing, the weighing device of the present embodiment to solve the above problem.It needs to illustrate
, the weighing device of the present embodiment can be assemblied in but be not limited to the matter storage lattice on refrigerator door, can also be assemblied in ice
On shelf and drawer in case compartment.
Bottom bracket 11 plays the role of support, while can share the stress of matter storage lattice bottom, is risen to matter storage lattice bottom
To the effect of protection, which has no effect on the result weighed.
Since 13 top of upper bracket needs to accept the scale pan 14, lower part needs to be fixedly connected with sensor body 12, in order to
Facilitate and fix upper bracket 13 and described two structures, as shown in figure 4, upper bracket 13 has middle concave concave portion 131 and position
The first wing side 132 on 131 two side top of middle concave concave portion, middle concave concave portion 131 pass through first connecting portion 15 and sensing
Device ontology 12 connects, and the first wing side 132 then connect with the scale pan 14, this structure make the formation solid space structure of upper bracket 13 into
Row load-bearing can buffer the stress directly with weight contact site, improve its service life.
As shown in figure 3, there is on the scale pan 14 at position corresponding with the wing side 132 recessed portion 141 to lower recess,
The recessed portion 141 and the structure on wing side 132 match, and wing side 132 is fixed with recessed portion 141, is played fixed-wing side 132, is prevented
The effect that upper bracket 13 is slided.
As shown in figure 4, in order to reduce the dead weight of upper bracket 13 active force, middle concave concave portion caused by bearing sensor
Lightening hole 133 is opened up on 131 bottom wall, to reduce the weight of upper bracket 13 to the greatest extent.
Bottom bracket 11 has intermediate projections portion and the second wing side on intermediate projections portion two side bottom end, intermediate convex
The portion of rising is connect with the sensor body, the drawer or partition board that the second wing side is used to be fixed in refrigerator, upper bracket 13
Structure it is similar with the structure of upper bracket 13 of back-off, the two reaches similar technique effect.
Specifically, first connecting portion 15 is the first connection being arranged in the wherein one end upper surface of sensor body 12
Hole, second connecting portion 16 are the second connecting hole being arranged in the other end lower surface of sensor body 12, sensor body
12 are threadedly coupled by the first gasket with the upper bracket 13, and sensor body 12 passes through second gasket and bottom bracket
11 are threadedly coupled.First gasket passes through for connecting upper bracket 13 and sensor body 12, while by the gravity of title article
One gasket is transferred to resistance-strain on piece, and the preferably thickness of the first gasket and the second gasket is 2-4mm.It is preferred that the first gasket and
The width of two gaskets is of same size with sensor body 12, as shown in figure 5, in the present embodiment, in sensor body 12
