Furthermore, the hanging weight arm structure further comprises a hanging weight arm 5, the hanging weight arms 5 are arranged on two sides of the connecting support 4 respectively, the lower end of each hanging weight arm 5 extends into the inner container 2 and is connected with the upper end of the tray support 6 to suspend the tray support 6 in the inner container 2, the design is reasonable and ingenious, the connecting support 4 and the tray support 6 are convenient to connect, and the tray support 6 is suspended in the inner container 2.
Preferably, the tray support 6 has a plurality of layers of support structures for placing the tray, so that a plurality of layers of food can be placed, and the food is convenient to place and take, thereby providing a basis for weighing the plurality of layers of food.
Further, be provided with on the diapire of inner bag 2 and block 7, block 7 and the lower extreme of tray support 6 and offset so that tray support 6 keeps the front and back level, its reasonable in design, ingenious can avoid tray support 6 to rock around, and then can improve the accuracy of weighing, reduce the error of weighing. The tray support 6 is in a suspended state in the liner except that the tray support 6 is in contact with the suspended weight arm 5 and the blocking piece 7.
In particular, a top bracket 401 is arranged at the upper end of the connecting bracket 4, the top bracket 401 abuts against the weight sensor 3, and the connecting bracket 4 can be conveniently hung on the weight sensor 3 through the arranged top bracket 401.

In this embodiment, the connected weight arm 5 and the tray support 6 are in an L-shaped structure, so that the weight of the food can be measured, the weighing accuracy is improved, and the weighing error is reduced.
Further, the inner container 2 is provided with a normally open air release hole, the inner container 2 is provided with a through hole 200, the suspended weight arm 5 extends into the inner container 2 through the through hole 200, and the gap area between the suspended weight arm 5 and the side wall of the through hole 200 is smaller than the area of the normally open air release hole. The weight arm 5 should maintain a proper gap through the through hole 200 of the inner container 2 to prevent the weight arm 5 from touching the inner container wall. Because the steam oven is provided with a normally open air release hole and is exhausted out of the box body 1 through the air outlet cavity 100. The area of the gap is smaller than that of the normally open air release hole, and the aperture of the through hole 200 is properly reduced to keep the normally open ventilation area unchanged.
Preferably, the box body 1 is provided with an air outlet cavity 100 communicated with the outside, and the weight sensor 3 is arranged at a position close to the air outlet cavity 100, so that heat dissipation is facilitated, and the weight sensor is easily isolated from a heat source, so that an independent heat insulation and dissipation space is formed, and the weight sensor is prevented from working at an ultrahigh temperature.
The weight sensor can adopt a single-point mode or a left-right sensor double-point mode. The double points are easier to ensure the left and right balance of the tray bracket, and the weighing is more accurate. The single-point support can fix the connecting bracket and the weight sensor together, and can also be placed on the weight sensor by using a left fulcrum and a right fulcrum. The food materials need to be placed in a balanced mode, so that the bracket is prevented from inclining or measuring errors are prevented from becoming large.
Preferably, the number of the weight sensors 3 is 1, and the weight sensor 3 is provided at an intermediate position of an upper end of the connection bracket 4. The single-point weight sensor is adopted, the connecting support 4 is fixed with the weight sensor 3, and the connecting support 4 is in contact with the 1 weight sensor 3 to form a weight fulcrum, so that the tray type single-point electronic weighing structure is formed. The connecting bracket 4 is equivalent to the tray, except that the weighed object of the electronic weighing of the tray is placed in the tray, and the heavy object of the structure is hung on the connecting bracket.
Or, the number of the weight sensors 3 is 2, and two sides of the upper end of the connecting bracket 4 are respectively arranged on the corresponding weight sensors 3. Namely, two-point weight sensors are adopted, and the weight sensors are arranged on the left side and the right side of the connecting bracket to form suspension type weighing. The weight measured by the two weight sensors is the same as the total weight suspended from the attachment bracket. Meanwhile, the connecting support 4 is in contact with the 2 weight sensors 3 to form two gravity fulcrums, and when the left and right gravity of the connecting support are unbalanced, the connecting support still keeps horizontal by adopting the two gravity fulcrums.
The weighing principle of the steam oven provided by the embodiment is described as follows:
the tray support 6 and the suspension arm 5 form an eccentric gravity structure, namely the suspension arm 5 and the top of the L-shaped tray support 6 are arranged on the same side. The tray support 6 is kept horizontal front and back by the stopper 7.
The left and right levels of the tray support 6 are ensured by fixing a connecting support (single point) or a left and right fulcrum (double point) which is integrated with the weight sensor 3. The forward and backward horizontal of the pallet support 6 is ensured by the suspension arm 5 and the stopper which cannot move forward and backward.
Since the weight sensor 3 is fixed above the inner container 2 and the suspension arm 5 is suspended on the weight sensor 3 by the connecting bracket 4, the force on the weight sensor 3 is the downward pulling force of the suspension arm 5.
The tray support 6 is an eccentric structure, under the action of gravity, the tray 8 has a pressure towards the direction of the box door, and under the action of the blocking piece 7, the tray support 6 cannot move forwards, namely cannot move towards the direction of the box door, and is kept in a horizontal state. See the weighing diagram of fig. 2.
In this embodiment, the blocking member 7 may be bilaterally symmetrical, or may be fixed to the bottom wall of the inner container 2 in a single point, and the blocking member 7 of this embodiment is disposed at a position on the inner container 2 near the door, or of course, the blocking member 7 may be disposed at other positions as long as it can ensure that the tray support is kept horizontal.
F is the friction force between the tray bracket and the blocking piece; k is the friction coefficient of the tray bracket and the blocking piece; p is the pressure of the blocking piece on the connecting bracket; g is gravity; f is the upward pulling force of the connecting bracket; theta is an included angle between the pulling force and the gravity; g' is the weight sensor pressure, which is derived from the acceptance diagram of fig. 3: p ═ F ═ SIN θ, F ═ K ═ P, G-F ═ COS θ, G ═ F ═ COS θ, K < 0.2%, so G ≈ G
When theta is 45 degrees, P is G;
when theta is greater than 45 degrees, P is greater than G;
when theta <45 DEG, P < G.
The gravity supporting point of the tray bracket 6 and the blocking piece ensure that the tray bracket keeps horizontal, and the friction force f between the tray bracket and the blocking piece is minimum, wherein P is more than or equal to 0.
Therefore, the larger the pressure P of the blocking piece on the connecting bracket is, the larger the friction force f between the tray bracket and the blocking piece is, and the larger the weighing error is. Therefore, heavy food materials are placed on the lower layer as much as possible, light food materials are placed on the upper layer, and moderate food materials are placed in the middle. And the measurement error caused by the fact that the included angle theta between the pulling force and the gravity is increased is reduced.
Meanwhile, the smaller the friction coefficient K between the tray support and the blocking piece is, the smaller the friction force f between the tray support and the blocking piece is, the closer the weight sensor pressure G' is to the gravity G, and the smaller the measurement error is. Of course, the blocking member 7 may be designed in the form of a ball or roller to further reduce friction and reduce measurement errors.
The metal friction coefficient is generally between 0.05% and 0.15%. The error due to friction is typically less than 0.15%. Taking the example of weighing 5KG, the total weight of the connecting bracket does not exceed 10KG, and 10KG is 0.15 percent and 15 g. Generally, the cooking weighing error can meet the requirement within 100 g. This scheme trades off the simplification of structural design with very little precision cost to easily realize the multilayer and weigh.
The calculation mode can be applied to single-point weighing and double-point weighing, if the calculation mode is applied to single-point weighing, the total gravity suspended on the connecting support can be obtained only by calculating the gravity measured by the weight sensor once, and the calculation mode is applied to double-point weighing, the gravity measured by the two weight sensors needs to be respectively calculated, and then the total gravity suspended on the connecting support can be obtained by adding the gravity measured by the two weight sensors.
The utility model discloses a steam oven receives the restriction at the structure, utilizes the equilibrium principle of power, reaches the purpose of weighing. The structural design is simplified, and the number of weight sensors is reduced. Advantages include, but are not limited to: simple structural design, the installation is dismantled easily. The cleaning is convenient and no dead angle exists. No hidden trouble of air leakage and water accumulation.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
