Referring to fig. 1 to 6, an embodiment of the present invention provides an induction cooker, including a housing 10 and a panel 20, the panel 20 includes a heating panel 21 and an operating panel 22, at least one set of weighing assembly is provided in the housing 10, and the weighing assembly includes a weight sensor 30, a desktop support frame 40 and a machine body connecting bracket 50.

The two ends of the desktop support frame 40 are respectively supported on the placing platform of the induction cooker through the support legs 60.

The body attachment bracket 50 is fixed relative to the housing 10.

The two ends of the weight sensor 30 are respectively connected to the desktop support frame 40, and the middle part of the weight sensor 30 is connected to the body connecting bracket 50.

The weight sensor 30 has two deformation portions 31 between both ends thereof.

In the existing electromagnetic oven, a weight sensor is generally arranged. In food cooking process, utilize weighing sensor to weigh and place the weight of eating the material in pan and the pan on the electromagnetism stove to according to the heating process of this weight adjustment electromagnetism stove, specifically can include but not limited to the heating temperature of adjustment electromagnetism stove, rate of rise and heat preservation time, make the electromagnetism stove can all have suitable branch cooking scheme to the pan of different weight and eat the material, promote food taste and nutrition.

At present, a weight sensor is generally positioned at the rear part of a machine body of an induction cooker, one end of the weight sensor is supported on a table board where the induction cooker is positioned through a support leg at the rear end of the machine body, the other end of the weight sensor is relatively fixed with a shell, and the weight sensor is electrically connected with a control board. The two ends of the weight sensor are respectively connected to the machine body and the desktop supporting legs, the middle of the weight sensor is provided with a deformation area with weakened strength, a resistance membrane is attached to the deformation area, the resistance of the resistance membrane changes when the deformation area deforms, and weighing values are converted by reading different resistances of the resistance membrane before and after weighing.

However, the current weight sensors are only arranged at local positions of the induction cooker, such as four corner positions in the shell of the induction cooker. Firstly, the weight sensors are arranged in a large number, so that the production cost of the induction cooker is improved. The weighing task is set up and accomplished to the weight sensor mutual independence of four turning positions, all sets up the position in being close to user one side based on coil panel, lamp plate and circuit board isotructure in the casing, and consequently the weight that is close to user one side in the casing is great, and whole electromagnetism stove inclines or squints towards this direction, leads to two weight sensors that are close to user one side to receive great effort, and keeps away from two weight sensors of user one side and receives less effort. Due to the arrangement, in the weight conversion process of the weight sensor, the algorithm program is complex, large measurement errors are easily caused, and the accuracy of weighing the weight is reduced.

Secondly, a plurality of weight sensors need to occupy a large amount of installation space in the casing to need to cooperate a large amount of assembly structure spare, increased its complexity of assembling, reduce assembly efficiency.

Furthermore, the position distribution span of a plurality of weight sensors in the casing is great, the temperature difference based on each position in the casing is great, the temperature that is close to user one side is higher than the temperature of keeping away from user one side, lead to the weight sensor that is close to user one side to receive the high temperature influence and take place the thermal expansion deformation, and the weight sensor that keeps away from user one side receives the high temperature influence less, consequently make the deformation difference of each weight sensor great, the complexity of the algorithm procedure in the weight conversion process of weight sensor has been increased, the accuracy of weighing of weight has been reduced. Therefore, the weight weighing precision of the weight sensor in the existing induction cooker is small, and the food cooking taste of the induction cooker is influenced.

To solve the above problem, the present embodiment provides an electromagnetic oven with a weighing assembly. Specifically, the induction cooker provided in this embodiment may be a planar induction cooker or a concave induction cooker shown in fig. 2, and the present embodiment does not limit the type of the induction cooker. The panel 20 is covered on the housing 10, and the two together enclose an accommodating cavity of the housing 10. The holding intracavity is provided with the weighing component isotructure that circuit board, lamp plate, cooling fan, coil panel and this embodiment provided.

Referring to fig. 3 and 4, the weighing assembly provided in this embodiment includes a weight sensor 30, a table top support 40, and a body attachment bracket 50. Wherein, the two ends of the desktop support frame 40 are supported on the placing table top of the induction cooker, and the desktop support frame 40 can be a rigid support, i.e. the desktop support frame can not generate or generate extremely small deformation after being applied with an acting force from the outside. Fuselage linking bridge 50 and casing 10 relatively fixed, both can be connected through the fastener, and convenient to detach and change in the use also can be integrated into one piece certainly for fuselage linking bridge 50 is higher in the stability of setting up on casing 10. The fuselage connection bracket 50 is made of a rigid material, that is, the fuselage connection bracket 50 is not easily deformed when being subjected to an external force, and the rigid material may include, but is not limited to, a ceramic material and a metal material with a relatively high strength. A weight sensor 30 is connected between the desktop support frame 40 and the body connecting bracket 50, and a deformation part 31 of the weight sensor 30 is located between a first end and a second end of the weight sensor 30 and is deformed correspondingly after being subjected to an external applied force. The deformation portion 31 may be a deformation member in the weight sensor 30, such as an elastic aluminum sheet and/or a spring, and the deformation portion 31 may also be a deformation region in the weight sensor 30, such as a hollow elastic body, wherein the hollow elastic body is the deformation region. It can be understood that, in practical use, the type and the measurement principle of the weight sensor 30, and the structure of the deformation portion 31 may be selected according to practical use, and refer to the existing weight sensor 30, which is not described in detail in this embodiment.

It should be noted that, in this embodiment, two ends of the table top supporting frame 40 are respectively connected to two supporting legs 60 with different orientations, so that when the induction cooker is tilted near the two supporting legs 60, the supporting legs 60 can transmit the orientation change state to the table top supporting frame 40 and the first end of the weight sensor 30 by applying a force in time, thereby forming a linkage relationship between the two supporting legs 60. Compared with the prior art, the weight sensors 30 are arranged at each supporting leg 60, the induction cooker of the embodiment can not only reduce the number of the weight sensors 30 in the accommodating cavity, enlarge the installation space of the accommodating cavity, and reduce the production cost of the induction cooker. More importantly, the first end of the weight sensor 30 of the induction cooker of the embodiment can simultaneously acquire the position change information of the two support legs 60 through the two ends of the desktop support frame 40, so that the measurement range is wider, the influence of the position change of the induction cooker on the weighing precision is reduced, the problem of errors which cannot be solved in the scheme of arranging the weight sensor 30 at each support leg 60 is reduced, and the weighing precision is improved.

The two ends of the desktop supporting frame 40 are supported on the placing table top through the supporting legs 60, as an implementation manner that can be realized, the bottom wall of the housing 10 is provided with avoiding holes 11 through which the supporting legs 60 can pass, and the supporting legs 60 are not in contact with the hole walls of the avoiding holes 11.

Referring to fig. 4, the supporting leg 60 of this embodiment is in contact with the placing table after passing through the avoiding hole 11, and the deformation of the deformation portion 31 is affected based on the contact between the first end of the weight sensor 30 and the body of the table top supporting frame 40 and the induction cooker, so that the supporting leg 60 and the avoiding hole 11 need to be set in a non-contact state, thereby improving the accuracy of the deformation portion 31, and ensuring that the weight sensor 30 can accurately weigh the cookware 90 and the weight of the food in the cookware 90.

As an implementation mode, the bottom of the supporting leg 60 is provided with a foot pad 61, which can be a plastic part and mainly plays a role of skid resistance, so that the placing stability of the induction cooker on the placing table top is ensured, and the use safety of the induction cooker is improved. Meanwhile, the support legs 60 can be stably contacted with the placing table top, and upward reaction force applied by the placing table top can be transferred to the weight sensor 30, so that the weighing precision of the weight sensor is ensured.

In use, when the pot 90 or the pot 90 containing food materials is placed on the heating panel 21, the pot 90 applies a downward force to the housing 10 of the induction cooker, the downward force is transmitted to the weight sensor 30 through the body connecting bracket 50, and the placing table applies an upward reaction force to the pot 90, and the upward reaction force is transmitted to the weight sensor 30 through the legs 60 and the table top supporting frame 40 connected to the legs 60 based on the fact that the pot 90 is in contact with the placing table top through the legs 60. The weight sensor 30 receives the acting force at the same time to cause the deformation of the deformation portion 31, and after the control board acquires the deformation amount, the weight of the pot 90 or the weight of the food in the pot 90 is converted according to the deformation amount.

Specifically, the deformation portion 31 is suspended between the desktop support frame 40 and the body connecting bracket 50. Deformation portion 31 does not take place the contact with any part and structure in the holding chamber promptly, can effectively reduce the influence that external structure produced deformation process of deformation portion 31 like this to improve the accuracy nature that weight sensor 30 weighed.

In the above-described induction cooker, the first end of the tabletop support frame 40 may alternatively extend to a side of the heating panel 21 close to the operation panel 22, or to a side of the heating panel 21 close to the operation panel 22.

The second end of the table top support 40 extends to a side of the heating panel 21 away from the operation panel 22, or extends to a side of the heating panel 21 close to the operation panel 22.

In the general electromagnetic oven, the operation panel 22 is closer to the user side than the heating panel 21, so that the user can input a control command on the operation panel 22. Therefore, the side of the heating panel 21 close to the operation panel 22 can be understood as the side of the induction cooker close to the user, and the side of the heating panel 21 far from the operation panel 22 can be understood as the side of the induction cooker far from the user. The both ends of desktop support frame 40 are towards being close to or keeping away from user one side extension respectively, or extend to being close to and keeping away from user one side, based on this, when the electromagnetism stove is being close to user one side or keep away from user one side and take place the position slope, can utilize desktop support frame 40 to weight sensor 30 transmission position change to acquire the change state of position change back weight, promote weighing sensor 30 and weigh the precision.

In one embodiment, the weight sensor 30 and the fuselage attachment bracket 50 have attachment points that are located at the geometric midpoint of the weight sensor 30 or are located near the geometric midpoint of the weight sensor 30.

It should be noted that, based on the pot 90 being placed on the induction cooker, a downward acting force is applied to the induction cooker, the acting force is transmitted to the weight sensor 30 through the body connecting bracket 50, and the connection point of the weight sensor 30 and the body connecting bracket 50 is arranged at the geometric midpoint of the weight sensor 30 or a position close to the geometric midpoint, so that the weight sensor 30 can receive the acting force applied from the body connecting bracket 50, and the acting force is mainly distributed at the geometric midpoint of the weight sensor 30 or a position close to the geometric midpoint, thereby avoiding generating a concentrated acting force at the edge position of the weight sensor 30, facilitating the deformation of the deformation portion 31 of the weight sensor 30 under the influence of the acting force, improving the sensitivity of the deformation portion 31 to the acting force, and increasing the detection accuracy of the weight sensor 30. Meanwhile, based on the weight sensor 30, the weight is calculated through the deformation amount of the deformation part 31, and the arrangement can reduce the complexity of an algorithm program in the calculation process, thereby reducing errors in the calculation process and improving the accuracy of the weight weighing result.

Referring to fig. 6, the connection point of the weight sensor 30 to the table top support 40 is near the geometric midpoint of the table top support 40.

It should be noted that, during the use of the induction cooker, the pot 90 applies a downward force to the induction cooker, which force can be indicated by a downward arrow a in fig. 6, and the force is transmitted to the gravity sensor 30 through the body connecting bracket 50, which force can be indicated by a downward arrow d in fig. 6. While the induction cooker is on the placing table, it will be subjected to an upward reaction force exerted by the placing table, which reaction force can be represented by an upward arrow b in fig. 6. The reaction force is transmitted through the legs 60 to the table top support 40 and from the table top support 40 to the weight sensor 30, which force may be represented by the upward arrow c in fig. 6. Therefore, the connecting point of the desktop support frame 40 and the weight sensor 30 is close to the geometric midpoint of the desktop support frame 40, so that the reaction force can be guaranteed to act on the weight sensor 30 in a balanced manner, the deformation of the deformation part 31 of the weight sensor 30 under the influence of the reaction force is facilitated, the sensitivity of the deformation part 31 to the response of the reaction force is improved, and the detection precision of the weight sensor 30 is improved.

As an alternative embodiment, referring to fig. 6, the geometric midpoint of the table top support 40, the geometric midpoint of the weight sensor 30, the connection point of the weight sensor 30 and the fuselage connection bracket 50, and the geometric midpoint of the fuselage connection bracket 50 are all located on the same straight line.

It should be noted that, based on the body connecting bracket 50, the acting force received by the induction cooker is transmitted to the weight sensor 30, and the desktop support frame 40 transmits the reaction force transmitted by the support leg 60 to the weight sensor 30, such a setting mode can ensure that the weight sensor 30 receives both the balanced acting force and the balanced reaction force, so as to facilitate the deformation portion 31 to generate corresponding deformation according to the acting force, and improve the accuracy of weighing the weight. Furthermore, the arrangement mode improves the balance of the whole structure of the induction cooker, reduces the assembly difficulty in the manufacturing process of the induction cooker and improves the production efficiency.

Specifically, as shown in fig. 4 and 6, the table top support 40 has a first mounting surface 41 facing the bottom wall side of the housing 10, and the body attachment bracket 50 has a second mounting surface 51 facing the panel 20.

The weight sensor 30 is connected between the first mounting surface 41 and the second mounting surface 51.

In the above-described installation method, the weight sensor 30 can be mounted and fixed by the first mounting surface 41 and the second mounting surface 51 together, so that the stability of mounting the weight sensor 30 can be improved. The first mounting surface 41 and the second mounting surface 51 form a protective structure for the weight sensor 30 from the upper side and the lower side thereof, respectively, thereby improving the stability of the weight sensor 30 in use.

As an achievable embodiment, two deformation portions 31 are provided on opposite sides of the connection point of the weight sensor 30 and the body attachment bracket 50, respectively.

It should be noted that the weight sensor 30 provided in the present embodiment includes two deformation portions 31, and the increase in the number of the deformation portions 31 helps to accurately obtain the amount of deformation of the weight sensor 30 after receiving an applied force. And, set up two deformation portions 31 in same weighing component, can reduce the quantity with the assembly parts of deformation portion 31 looks adaptation, for example desktop support frame 40 and fuselage linking bridge 50, consequently can reduce the quantity and the required space of installation of structure spare in the holding chamber, avoid producing the influence to the installation of all the other structure spares in the holding chamber, simplify the assembling process to improve assembly efficiency.

Further, the two deformation portions 31 are respectively provided on opposite sides of the connection point of the weight sensor 30 and the body attachment bracket 50, and the direction may also be a direction toward the user side and a direction away from the user side based on the extension of both ends of the weight sensor 30 toward and away from the operation panel 22, respectively. In this direction, the weight distribution of the induction cooker and the heat distribution in the accommodating chamber have a large difference, and generally the weight is larger on the side close to the user, and the temperature in the accommodating chamber is higher, while the weight is smaller on the side far away from the user, and the temperature in the accommodating chamber is lower. And the pan is placed on the electromagnetism stove, can vibrate when the boiling takes place for the pan, and the process of vibration also can lead to the focus of electromagnetism stove to squint towards being close to user one side.

To above problem, this embodiment sets up two deformation portions 31 respectively on being close to user one side and keeping away from two directions of user one side, can measure the weight change when the electromagnetism stove takes place to squint and slope through the deformation portion 31 of different positions respectively to different position deformation portions 31 also can produce corresponding deformation according to the heat quantity difference in the holding chamber, thereby eliminate prior art, electromagnetism stove offset and heat distribution all cause the lower problem of accuracy is got to weight.

In practical use, the user can set the specific number of the deformation portions 31 according to practical needs, which is not limited in this embodiment.

As an achievable embodiment, with reference to fig. 3 and 4, the weighing assemblies are in two groups, two groups being located on the left and right sides of a line of symmetry between the geometric center of the heating panel 21 and the projection of the geometric center on the bottom wall of the casing 10.

It should be noted that, in this embodiment, the weighing assemblies are two sets, and two sets of weighing assemblies are located the relative left and right sides of line of title respectively, can guarantee the symmetry of electromagnetism stove overall structure like this to improve the stability of its structure. Here, the left-right direction of the induction cooker may be the left-right direction shown in fig. 2, and the front-back direction of the induction cooker may be the front-back direction shown in fig. 2. The geometric center of the heating panel 21 may be the point shown as S in fig. 2. Further, when the position of any one of two sides of the symmetry line of the induction cooker is changed, the weighing assembly can acquire the change of the weight in the change of the position. The desktop support frame 40 in every group weighing component extends along the direction that is close to and keeps away from operating panel 22, and the extending direction of supposing desktop support frame 40 is the first direction, and the place direction of two sets of weighing component geometric centre lines is the second direction, and first direction and second direction can be for being certain contained angle setting, and this contained angle can be the right angle. Such setting can be through every group weighing component change information of weight when acquireing the first direction orientation change, change information of weight when acquireing the second direction orientation change through two groups weighing component to acquire the state that each orientation of electromagnetism stove changes, and accomplish the accurate measurement of weight.

It should be noted that, when the operation panel is in a symmetrical shape such as a rectangle, a circle, an ellipse, etc. shown in fig. 2, the symmetrical line provided in the present embodiment may also be a connecting line between the geometric center of the operation panel and the geometric center of the heating panel.

As a preferred embodiment, the two sets of weighing modules are symmetrically arranged on a symmetry line, and the two body connecting brackets 50 of the two sets of weighing modules are located between the two desktop supporting frames 40 of the two sets of weighing modules. Therefore, the complexity and the assembly difficulty of the whole structure of the induction cooker can be reduced, and the weighing precision of the weighing component is improved.

Specifically, a fixing member 70 for fixing the body connecting bracket 50 is arranged between the body connecting bracket 50 of each weighing assembly and the bottom wall of the casing 10, and a reinforcing rib 80 is arranged between two fixing members 70 corresponding to the two weighing assemblies. It should be noted that, the fixing member 70 and the reinforcing rib 80 are arranged in the housing 10 of the induction cooker, so that the stability of the connection between the machine body connecting bracket 50 and the housing 10 is improved, and the weighing precision of the weighing assembly is ensured.
