The invention realizes the automatic control of the food supporting frame through the normally closed switch for setting the heating position and the normally closed switch for setting the moving-out position, thereby having simple operation, ensuring the use safety of users, avoiding scalding accidents and accurately feeding the food supporting frame to the optimal heating position in the furnace cavity.
Description
1, technical field:
The present invention is a kind of control device that is used to control food supporting frame turnover furnace chamber that uses in cooking food stove and accessorys such as micro-wave oven, baker, belongs to the renovation technique of food supporting frame in-out control device.
2, background technology:
In cooking food stove and accessorys such as existing micro-wave oven, baker, heating location and the bearing support operation taken furnace chamber outside of its food supporting frame that is used to place food in sending furnace chamber to all leans on the user manually to finish, troublesome poeration not only, waste time and energy, and temperature was all higher when bearing support heated in furnace chamber with food, and the user is absolutely unsafe in the operating process of manually bearing support being taken outside the furnace chamber, and the user has not very slightly, will cause scalding, be difficult to guarantee that the user's is safe in utilization; In addition, manual operation also is difficult to guarantee exactly food supporting frame to be sent to the best heating location in the furnace chamber, so that influence the efficiency of heating surface of stove and accessory, makes prolongation heat time heating time of food, has also influenced the cooking effect of food.
3, summary of the invention:
The objective of the invention is to consider the problems referred to above and provide a kind of not only simple to operate, time saving and energy saving, and can guarantee the safe in utilization of user, avoid taking place the scald accident, and can exactly food supporting frame be sent to the in-out control device of the food supporting frame of the best heating location in the furnace chamber.The present invention can improve the efficiency of heating surface of stove and accessory, saves the heat time heating time of food, guarantees the cooking effect of food.
Circuit theory diagrams of the present invention as shown in Figure 1, include power switch (K1), motor (T), often open energizing switch (K4), set outflow location first normally closed switch (K2), set second normally closed switch (K3) of heating location, wherein the series circuit formed of first normally closed switch (K2) and second normally closed switch (K3) is with often to open energizing switch (K4) in parallel, one end of this parallel circuit is connected with the live wire (L) of power supply with motor (T) and power switch (K1) serial connection back, and the other end of this parallel circuit is connected with the zero line of power supply (N).
Also be connected with protective tube on above-mentioned power switch (K1) and the circuit that the live wire (L) of power supply is connected.
Above-mentioned first normally closed switch (K2) and second normally closed switch (K3) are normally closed microswitch.
The above-mentioned energizing switch (K4) of often opening is manual switch or delay switch.
The present invention by setting heating location normally closed switch and the normally closed switch of setting outflow location to realize controlling automatically the turnover of food supporting frame, therefore, it is not only simple to operate, time saving and energy saving, and can guarantee that the user's is safe in utilization, avoid taking place the scald accident, and can exactly food supporting frame be sent to the best heating location in the furnace chamber.The present invention is a kind of efficiency of heating surface that improves stove and accessory, saves the heat time heating time of food, guarantees the in-out control device of the food supporting frame of cooking food effect.
4, description of drawings:
Fig. 1 is circuit theory diagrams of the present invention.
5, the specific embodiment:
Embodiment:
Circuit theory diagrams of the present invention as shown in Figure 1, include power switch K1, motor T, often open energizing switch K4, set outflow location the first normally closed switch K2, set the second normally closed switch K3 of heating location, wherein the series circuit formed of the first normally closed switch K2 and the second normally closed switch K3 is with often to open energizing switch K4 in parallel, one end of this parallel circuit is connected with the live wire L of power supply with motor T and power switch K1 serial connection back, and the other end of this parallel circuit is connected with the zero line N of power supply.In the present embodiment, the above-mentioned first normally closed switch K2 and the second normally closed switch K3 are normally closed microswitch.The above-mentioned energizing switch K4 that often opens is manual switch or delay switch.
Because microswitch K2 is normally closed switch, when the user puts raceway in the stove to food supporting frame, when food supporting frame shifted out the outer position of setting of furnace chamber, food supporting frame was pushed down K switch 2, and K switch 2 disconnects, and food supporting frame stops to move outside furnace chamber.In like manner, because microswitch K3 is a normally closed switch, when food supporting frame moved to the heating location of setting in the furnace chamber, food supporting frame was pushed down microswitch K3, and microswitch K3 disconnects, and food supporting frame stops to move in furnace chamber again.
In order to ensure the security of using,, also be connected with protective tube Fuse on above-mentioned power switch K1 and the circuit that the live wire L of power supply is connected in order to avoid circuit burns out members such as motor when being short-circuited.
The present invention is contained in the cooking food stove and accessorys such as micro-wave oven, baker and uses, when the user after putting food on the food supporting frame, food supporting frame need be delivered to furnace chamber the inside and go, then operate as follows:
If the electric loop of forming through " power supply L line, protective tube Fuse, power switch K1, motor T, energizing switch K4, power supply N line " is loop 1; The loop of forming through " power supply L line, protective tube Fuse, power switch K1, motor T, microswitch K2, microswitch K3, power supply N line " is loop 2.
The user presses power switch K1, when the user presses energizing switch K4 again, and loop 1 conducting, motor begins to rotate, and drives the food supporting frame motion.After food supporting frame leaves K switch 2, the K2 closure, this moment, K4 unclamped, and then loop 1 disconnects, when food supporting frame does not reach K switch 3, loop 2 conductings, motor remains in operation, and food supporting frame continues to move towards the furnace chamber the inside.When food supporting frame arrived microswitch K3, microswitch K3 disconnected, and then loop 2 disconnects, and motor shuts down, and food supporting frame is put just to position in the stove of setting.
After food cooking has been got well, the high temperature food bearing support in the stove need be shifted out so that get food, then operate as follows:
Press energizing switch K4, then loop 1 conducting, the motor entry into service, food supporting frame begins to move.After food supporting frame leaves K switch 3, the K3 closure, this moment, K4 unclamped, and loop 1 disconnects, before food supporting frame arrives the K2 place, loop 2 conductings, motor remains in operation, and food supporting frame continues outwards to move.When food supporting frame arrives K2, touch the K2 action, loop 2 disconnects, and motor shuts down, and food supporting frame stops to move.
