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 first manual switch (K1), second manual switch (K2), two-way controllable motor (T), set first normally closed switch (K3) of heating location, set second normally closed switch (K4) of outflow location, wherein first normally closed switch (K3) is connected with first manual switch (K1) and two-way controllable motor (T), second normally closed switch (K4) is connected with second manual switch (K2) and two-way controllable motor (T), two series circuit parallel connections, one end of this parallel circuit is connected with the live wire L of power supply, and the other end of this parallel circuit is connected with the zero line N of power supply.
Also be connected with protective tube (Fuse) on above-mentioned parallel circuit and the circuit that the live wire L of power supply is connected.
Above-mentioned second normally closed switch (K4) and first normally closed switch (K3) are normally closed microswitch.
Above-mentioned first manual switch (K1) and second manual switch (K2) are key 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 the first normally closed switch K3 of first manual K switch 1, the second manual K switch 2, two-way controllable motor T, setting heating location, the second normally closed switch K4 of setting outflow location, wherein the first normally closed switch K3 connects with the first manual K switch 1 and two-way controllable motor T, the second normally closed switch K4 connects with the second manual K switch 2 and two-way controllable motor T, two series circuit parallel connections, one end of this parallel circuit is connected with the live wire L of power supply, 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 second normally closed switch K4 and the first normally closed switch K3 are normally closed microswitch.The above-mentioned first manual K switch 1 and the second manual K switch 2 are key switch.
Because microswitch K4 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 4, and K switch 4 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 parallel circuit 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.
If the loop of forming through " power supply L line, protective tube Fuse, motor T, key switch K1, microswitch K3, power supply N line " is loop L1.
If the loop of forming through " power supply L line, protective tube Fuse, motor T, key switch K2, microswitch K4, power supply N line " is loop L2.
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:
The K switch 1 that pushes button, loop L1 conducting, two-way controllable motor T begins the forward running, and food supporting frame begins to move towards furnace chamber is inner.When food supporting frame arrives microswitch K3 place (according to the design needs, can arrive bosom in the furnace chamber), touch K3, K3 disconnects, and then loop L1 disconnects, and motor T shuts down, and food supporting frame stops to move.
In the process that food supporting frame moves in the furnace chamber, key switch K1 can unclamp arbitrarily with the need, in case unclamp, loop L1 disconnects, food supporting frame then stops the optional position to need during the course, during closed once more K1, can continue again in furnace chamber, to move, until touch till the microswitch K3.
Culinary art need be shifted out the high temperature food bearing support in the stove so that get food after having got well, and then operates as follows:
The K switch 2 that pushes button, loop L2 conducting, two-way controllable motor T begins antiport, and food supporting frame begins to move outside furnace chamber.When food supporting frame arrives microswitch K4 place (according to the design needs, can arrive furnace chamber the most outward), touch K4, K4 disconnects, and then loop L2 disconnects, and motor T shuts down, and food supporting frame stops to move.
In the process that food supporting frame moves in the furnace chamber, key switch K2 can unclamp arbitrarily with the need, in case unclamp, loop L2 disconnects, food supporting frame then stops the optional position to need during the course, during closed once more K2, can continue again outside furnace chamber, to move, until touch till the microswitch K4.
