The opening end of the heating pipe support is an infrared output end, and the opening end forms an annular range which is a front heating area.
In some embodiments of the present invention, since the elastic member 5 and the second guide member 14 for limiting the elastic member 5 are disposed below the container support 22, and the lifting device 4 is located below the container support 22, the distance between the lifting device 4 and the heating device 3 is relatively long. Alternatively, a part of the heating member support 32 may extend toward the elevating device 4 so as to be connected to the driving member 43, and a connecting member 6 may be provided between the heating member support 32 and the driving member 43. In one embodiment, as shown in fig. 1, 2, 4, 5, 6, 8, 9 and 11, a connector 6 is provided between the heating member support 32 and the driving member 43, the connector 6 being used to transmit the displacement of the driving member 43 to the heating member support 32 and the heating member 31. In addition, the installation space of the heating device 3, the cooking container 2 and the lifting device 4 in the base 1 can be increased through the connecting piece 6, and the spatial arrangement is convenient. A groove 321 is formed in the heating element support 32, the connecting element 6 is a columnar element, and the connecting element 6 is inserted into the groove 321.
Wherein, the connection between the connector 6 and the heating member support 32 can be a detachable connection or a non-detachable connection, when the connector 6 is detachably connected with the heating member support 32, the connector 6 is prevented from being separated from the heating member support 32 by the gravity of the heating member support 32 and the heating member 31.
In some embodiments of the present invention, the bottom end of the connecting member 6 is connected to one end of the transmission member 43, and the bottom end of the second guiding member 14 is connected to the other end of the transmission member 43, so that the transmission member 43 can be directly and fixedly connected to the connecting member 6 and the second guiding member 14, or the transmission member 43 can be used to tie a knot on the connecting member 6 and the second guiding member 14. In one embodiment, as shown in fig. 9 and 10, a first coupling hole 61 is provided at a bottom end of the coupling member 6, a second coupling hole 222 is provided at a bottom end of the second guide 14, both ends of the driving member 43 pass through the first coupling hole 61 and the second coupling hole 222, respectively, and the diameter of a portion passing through the first coupling hole 61 and the second coupling hole 222 is enlarged or knotted to prevent the driving member 43 from being disengaged from the first coupling hole 61 and the second coupling hole 222.
In some embodiments of the present invention, as shown in fig. 1, 2, 4, 7, 8, 10 and 11, a third guide 221 is further provided on a side of the container holder 22 facing the lower case 12, and the third guide 221 cooperates with the second guide 14 to limit the inclination of the elastic member 5 in both directions.
In some embodiments of the invention, the number of connectors 6 is equal to the number of lifting devices 4. More closely, elevating gear 4 is provided with at least two sets, and at least two sets of interval evenly set up in base 1. The number of the lifting devices 4 is positively correlated with the stability during the lifting of the cooking container 2 and the lifting of the heating device 3, but is positively correlated with the structural complexity of the cooking container 2 as a whole, and therefore, the number of the lifting devices 4 and the number of the connecting members 6 need to balance the lifting stability and the structural complexity. Each position of the container body 21 can synchronously descend through at least two groups of lifting devices 4 and two connecting pieces 6, the moving amount of the transmission pieces 43 in at least two groups of lifting devices 4 is the same, finally, each position of the heating device 3 can synchronously descend, and in the synchronous descending process, the areas of heat radiation applied to different positions of the heating device 3 are the same, so that the heating uniformity is improved. In one embodiment, the lifting devices 4 are provided in two sets, and the two sets of lifting devices 4 are symmetrically arranged in the base 1.
The present invention also provides a control method of a cooking appliance, which is used for the cooking appliance in the above embodiment, and includes:
controlling the heating device 3 to operate;
acquiring the position of the cooking container 2;
and controlling the heating device 3 to stop running according to the preset position reached by the cooking container 2.
According to the control method of the cooking appliance provided by the embodiment of the invention, in the cooking process, if the current weight of the food material is reduced to be lower than the safe value, the container body 21 is lifted to the preset position, and the heating device 3 is lowered to the limit position, the safety protection mechanism of the device is triggered, the power supply of the heating element 31 is immediately cut off, and the condition of dry burning is prevented.
As shown in fig. 11 (a), when there is no food in the cooking container 2, the elastic member 5, the heating device 3, and the lifting device 4 are all in the default equilibrium positions.
As shown in fig. 11 (b), when a proper amount of food is loaded into the container body 21, the elastic member 5 is forced to be compressed downward due to the increased weight, and the container holder 22 and the container body 21 are moved downward along with the elastic member 5. Since the driving string is connected to the container support 22, one end of the driving string moves down along with the container support 22, and accordingly, the other end of the driving string moves up, and since the other end of the driving string is connected to the connecting member 6, the connecting member 6 moves up along with the driving string, thereby moving the heating apparatus 3 upward.
The larger the weight of the food material loaded in the container body 21, the larger the amount of deformation of the elastic member 5 compressed, the larger the height of the container holder 22 and the container body 21 lowered, and the larger the height of the heating device 3 raised. Regardless of the weight of the added food material, the final stable state is formed in which the front heating range of the heating device 3 corresponds to the center position of the food material, and when the maximum amount of the food material is reached, the cooking container 2 is as shown in fig. 11 (c).
In the heating process, the moisture of the food materials can be continuously evaporated and lost, and the weight of the food materials is continuously reduced. Accordingly, the deformation of the elastic member 5 is reduced, the position of the container holder 22 and the container body 21 is moved upward, and the position of the heating means 3 is moved downward. In a real-time steady state, the front heating range of the heating device 3 corresponds to the center position of the food material, as shown in fig. 11 (d).
After the cooking is finished and the food is taken out, the cooking container 2 is again in the equilibrium position as shown in fig. 11 (e) by the cooking container 2, the elastic member 5, the heating device 3 and the lifting device 4.
In the heating process, when the weight of the food material is reduced to be lower than a safety value, the position of the container support 22 is moved up to the upper limit of the safety height, at the moment, the container support 22 is in contact with the micro switch 7, the micro switch 7 is triggered, the control system cuts off the power supply of the heating element 31, and the heating of the food material is immediately stopped. The logic realizes a safety protection mechanism, when the weight loss of the food is large, the heating is immediately stopped, and the condition of dry burning caused by too little food is prevented.
The above description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
