Description

DRIVING CIRCUIT OF COOKING OVEN OF PIZZA TO USE CONVEYOR SYSTEM}

The present invention relates to a driving circuit of a pizza cooking oven using a conveyor system. In particular, the pizza heater is cooked within a short time by operating the turbo heater, which is an auxiliary heater, with a voltage adjustable volume in addition to the main heater. By easily cooling the remaining heat in the oven is to effectively prevent burnout of the components constituting the cooking oven. In general, a pizza cooking oven using a conveyor system electrically heats the main heater to heat the inside of the oven, and heats the hot air heated by the main heater by the internal blower motor to be heated in the conveyor. By contacting the pizza being transported, the pizza can be cooked within a set time.

As such, the cooking of pizza by conventional hot air heats the inside of the oven using only the main heater, so that the pizza can not be baked more quickly, so the time and expense of cooking the pizza is great, especially when the power supply to the oven is cut off. The remaining heat in the main body causes a fatal damage to each component configured in the oven, resulting in a cost reduction due to the replacement of the parts and consequently shortening the life of the oven, resulting in a decrease in product reliability.

Therefore, the present invention bakes the pizza in a faster time, effectively shortens the cooking time of the pizza, thereby improving the productivity of the pizza as well as lowering the cost of the product. In addition, even when the oven power is cut off until a certain temperature is reached. The purpose is to cool the inside of the oven to prevent burnout of the components that make up the oven, so that continuous use of the cooking oven can be expected.

The present invention uses a turbo heater whose voltage is changed by a volume switch in addition to the main heater so that the pizza can be baked more quickly, and senses the temperature inside the oven to cool the inside of the oven until it reaches a certain temperature. Make it a technical task.

The present invention for achieving the above object in the parallel connection of a contactless controller, a digital temperature controller, a blower motor, a cooling fan motor, a DC conveyor transport reducer and a main heater, in parallel to the main heater to connect the turbo heater And a turbo volume switch and a heater connecting magnet in series with the turbo heater, but a temperature sensor contact is connected in series with a blower motor connecting magnet connected in series with a blower motor and a cooling fan motor. .

1 is a perspective view showing the appearance of a cooking oven to which the present invention is applied, and FIG. 2 is a circuit diagram of the present invention.

As shown in FIG. 1, in the present invention, the cooking oven main body 100 is largely configured at one lower end of the front side, and the operation unit 102 provided for the movable operation of the main body 100 and one side central portion of the side of the open main body 100 are provided. Conveyor system 101, which is configured to draw pizza at both ends and is ready to be cooked between transfers, and both sides of the pizza support, which are supported on both extension lines of the conveyor system and are ready to put pizzas and cooked pizzas ready for cooking. When the blower motor is driven while the main heater is heated by the operation of the manipulation unit 102, the blower motor may be blown by the blower to blow the main body 100 through the conveyor system 101. It takes a series of cooking structures that allow pizza to be transported inside to be baked naturally.

However, the present invention avoids the cooking structure using only the heating of the main heater in this way to bake the pizza more quickly to shorten the cooking time, and when the temperature inside the cooking oven becomes below a certain temperature even if the cooking oven is turned off. By cooling the inside of the oven until it prevents damage to the internal parts and extends the service life of the oven.

The circuit configuration of the present invention cooking oven is as follows.

The present invention parallels a solid state controller (SSR), a digital temperature controller (DT), a blower motor (BM), a cooling fan motor (FM _1, FM ₂ ), a DC conveyor transport reducer (SR) and a main heater (MH) in parallel. In connection, the turbo heater TH is connected in parallel with the main heater MH, and the turbo heater volume VR and the heater connection magnet MG _{1 are} connected in series with the turbo heater TH. Pizza, which is connected to the blower motor (BM) and the cooling fan motors (FM _1, FM ₂ ), in series with the blower motor connection magnet (MG ₂ ) in series. It provides a driving circuit for a cooking oven.

In the drawing, (VM) is a 12V voltmeter, (TR) is a 220/12 decompression transformer.

According to the present invention, the main heater (MH) of the digital temperature controller (DT) is supplied by supplying power to the main heater (MH) by connecting the fuse (FUSE) and the main switch (SW ₁ ) to the power supply (AC220) line. Heated by control, and this heating is intermittently and continuously heated by the operation of the contactless controller (SSR), blower motor (BM) and cooling fan motor (FM _1, FM ₂ ), 12V DC conveyor transport reducer (SR ) Will be operated to convey the heated system and blow the heat generated by the blower (not shown) connected to the blower motor BM to cook the pizza.

The operation of the cooking oven as described above is the same as the conventional operation description.

However, the present invention requires a large amount of heat when cooking a large amount of pizza at a time, and at this time, the turbo volume switch (SW ₂ ) is turned on (ON) to turn on the turbo lamp 15, followed by the heater volume for the turbo. By controlling the voltage by (VR) to selectively use up to 1-4KW, and by adjusting the turbo heater volume (VR) to heat the turbo heater (TH) to the turbo in addition to the main heater (MH) The heater TH may be heated to easily increase the temperature in the cooking oven, thereby significantly reducing the cooking time of the pizza.

On the other hand, if the power supply to the oven is cut off after cooking the pizza, all operations of the cooking oven are stopped. If the temperature in the oven is higher than a predetermined temperature (80 ° C), the contact 11 by the temperature sensor is kept on. By keeping the (ON) state, the blower motor (BM), DC conveyor transport reducer (SR) and cooling fan motors (FM _1, FM ₂ ) are operated to quickly cool the inside of the oven, whereby the temperature in the oven Below 80 ° C, the blower motor (BM), DC conveyor transport reducer (SR) and cooling fan motors (FM _1, FM ₂ ) are automatically stopped.

The present invention operates the turbo heater, which is an auxiliary heater, in addition to the main heater, so that the pizza can be cooked within a short time, thereby increasing the productivity of the pizza, reducing the manufacturing cost, reducing the waste of power, When the power supply is cut off, the remaining heat in the oven can be easily cooled to effectively prevent the burnout of components constituting the cooking oven, thereby greatly extending the life of the cooking oven, thereby ensuring the quality and reliability of the cooking oven. have.
