The present invention relates to the technical field of gas ovens, and in particular, to a temperature controller for a gas oven and the gas oven using the temperature controller.
An oven is a device that forms hot air to bake and cook food, and is generally a closed or semi-closed structure. Ovens are also called oasts, toasters, and roasters, and those heated with hot air in an open form are called barbecues. In a general sense, an oven also refers to a device that performs high-temperature treatment with hot gas. Traditional ovens use wood and coal for burning and heating. Modern ovens are multi-functional and use electric heating or natural gas. Ovens are divided into a single-layer type, a double-layer type and a three-layer type. Each layer can be controlled independently and can be used at the same time.
Currently, most gas ovens do not provide precise temperature control, and it is thus difficult to adjust to the appropriate temperature in use, resulting in much inconvenience during use. Moreover, the flame adjustment of gas ovens typically requires manual adjustment by the user, which is time-consuming, laborious and extremely inconvenient. Additionally, gas ovens generally lack heat dissipation of internal electronic components, which increases the risk of damaging the internal electronic components, thereby seriously affecting use. Furthermore, gas ovens typically rely on external power sources for electrical connection and thus have limitations on where they can be placed, resulting in limited utility.
In view of the shortcomings in the prior art, the present invention provides a temperature-controlled gas oven, which solves the problems and limitations of accurate temperature control, requirement for manual adjustment by the user, no heat dissipation for internal electronic components, and the requirement for an external power supply.
In order to achieve the above-mentioned objective, the present invention provides the following technical solutions.
The present invention provides a temperature controller for a gas oven, including a control module, a temperature measurement module, a prompt module, and a gas regulating module.
The control module is connected to the temperature measurement module, the prompt module, and the gas regulating module, respectively, to transmit a signal, and realizes automatic temperature control adjustment through stepwise adjustment and stepless linear adjustment. The temperature measurement module is arranged in the oven to measure a temperature in the oven and return the temperature to the control module.
The prompt module is configured to receive an excessive temperature or a normal temperature of the control module, and provide a prompt.
The gas regulating module is configured to receive a temperature and a control quantity returned by the control module, and control an air intake quantity, to adjust the temperature or turn on or turn off the oven.

In the present embodiment, the model of the ARM (or 8051) chip-based controller 28 is FX1S-30MT-001, the model of the temperature sensor 11 is WZPB-230, the model of the solenoid valve 36 is 2-way normally closed, the model of the proportional valve 35 is ITV2050-312L, and the model of the temperature regulating valve 34 is ZDLP. Through the cooperation of the hob and the temperature sensor 11, the temperature of the hob can be accurately monitored in real time. Through the cooperation of the communication module 30 and the ARM (or 8051) chip-based controller 28, the user can use a mobile phone to communicate with the communication module 30 through a network signal, and then transmit an instruction signal to the communication module 30 through the mobile phone. Subsequently, the communication module 30 transmits the instruction signal to the ARM (or 8051) chip-based controller 28, and the ARM (or 8051) chip-based controller 28 transmits electrical signals to the temperature regulating valve 34, the proportional valve 35, and the solenoid valve 36 according to the preset instruction, thereby automatically adjusting the gas stove.
The ignition and flame-off button 40 for the gas oven is installed on the front panel. The gas is supplied to the gas oven through the gas supply pipeline 39 that includes the solenoid valve 36. In addition, the gas supply pipeline 39 further includes the temperature regulating valve 34 that can be manually operated by the user. During combustion operation, the temperature controller further includes the temperature sensor 11, the first indicator light 41, the second indicator light 42 and the prompt buzzer 43, as well as a control circuit unit that uses a power supply as an operating power source to control the actions of the solenoid valve 36, the first indicator light 41, the second indicator light 42, and the prompt buzzer 43, etc. The ignition electrode 46 is an igniter that generates spark discharge. The temperature sensor 11 feeds data back to the control module, and the control module controls the solenoid valve drive circuit and the solenoid valve 36 for temperature control.
In the present embodiment, a method for the automatic temperature control adjustment includes: the temperature sensor 11 first detects a corresponding temperature signal and feeds the temperature signal back to the control module. The control module controls the on-off and magnitude of the current of the silicon-controlled rectifier for stepwise adjustment to control the solenoid valve drive circuit, so as to meet the temperature requirements for the oven.

The user performs an ignition operation by operating the ignition and flame-off button 40 for the gas oven, and monitors the temperature data supplied by the temperature sensor 11 through the sensor signal input circuit. In addition, when the measured temperature reaches or exceeds the preset temperature (for example, 260° C.) for the gas oven, the controller drives the circuit proportional valve through the solenoid valve to adjust the air intake quantity of the proportional valve. Through a light drive circuit, the indicator lights 41 and 42 are intermittently energized. The prompt buzzer 43 is energized through a buzzer drive circuit, so that the prompt buzzer 43 continuously buzzes for a preset time.

When the hob 14 is heated, the temperature sensor 11 monitors the temperature of the hob 14 and converts real-time temperature data into electrical signals and transmits the electrical signals to the ARM (or 8051) chip-based controller 28. The ARM (or 8051) chip-based controller 28 compares the real-time temperature data with the preset temperature data, and adjusts the gas intake quantity and air intake quantity in real time according to the comparison results. When the equipment is running, the fan 24 is activated to continuously blow out the air inside the control chamber 33 through the heat dissipation port 29. A negative pressure is formed inside the control chamber 33, and the outside air is drawn into the control chamber 33 under the action of atmospheric pressure, thereby forming a circulating air passage inside the control chamber 33, so as to dissipate heat inside the control chamber 33.
