Description

Technical Field

[0001] The utility model relates to the field of household gas stoves, in particular to an intelligently controlled gas stove. Background Art

[0002] With the improvement of living standards, people have higher and higher requirements for the intelligence of gas stoves. Most of the household smart gas stoves on the market currently have complex functions and cumbersome operations. Some users cannot adapt to the process of changing from simple knob operation to complex touch screen operation. In addition, the large number of electronic components leads to high cost of the whole machine and high price, which is unaffordable for ordinary users. Simple smart control stoves cannot achieve intelligent cooking with stable temperature control. Summary of the invention

[0003] The purpose of the utility model is to provide an intelligent gas stove, which combines the traditional conventional mode with the intelligent mode, adds a bistable valve for controlling the main fire on the basis of the ordinary plug valve, and replaces the hand-push solenoid valve with a self-priming solenoid valve to form an intelligent control plug valve, so that the fire power control of the conventional cooking mode and the intelligent cooking mode are both executed by the intelligent control plug valve, without the need to use additional complex proportional valves or stepper motors, and can achieve stable temperature control while alleviating the problems of complex structure, cumbersome operation and high cost in the intelligent gas stove technology.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions: A smart control plug valve, including a plug valve body, a valve stem, an air intake channel, and a main fire channel and a small fire channel for providing gas to a burner, wherein the air intake channel is equipped with a self-priming solenoid valve controlled by an electrical signal.

[0005] A smart gas stove includes a display assembly, a controller, a temperature sensor, a burner assembly and the aforementioned smart control plug valve; the display assembly and the temperature sensor are electrically connected to the controller respectively, the controller is electrically connected to the smart control plug valve, and the smart control plug valve connects the gas source and the burner assembly.

[0006] Furthermore, the controller is connected to a thermocouple to determine the working state of the cooker. When an unexpected flameout occurs, the controller sends a signal to shut off the self-priming solenoid valve on the intelligent control plug valve, thereby realizing an unexpected flameout protection function.

[0007] Furthermore, the main fire channel of the burner assembly connected to the intelligent control plug valve or the main fire channel integrated with the intelligent control plug valve is equipped with an electric control valve for controlling on and off.

[0008] Furthermore, the electrically controlled valve is a bistable valve or a self-priming solenoid valve.

[0009] The operation of the smart gas stove is divided into a normal mode and a smart mode. In the normal mode, the firepower is controlled by manually rotating the stopcock. The smart mode function gear is divided into at least four gears: healthy stir-fry, frying, steaming, and soup making. The smart cooking mode is switched through the "function selection button" of the display component.

[0010] Furthermore, the display assembly also includes a button "+" and a button "-" for setting the temperature or time.

[0011] Furthermore, when "healthy stir-fry" or "frying" of the intelligent mode function file is selected through the "function selection button", the display component displays the corresponding mode and the temperature setting value at the same time. The temperature is set by using the "+" and "-" buttons of the display component, and the set temperature is transmitted to the controller; the controller receives the pot temperature signal fed back by the temperature sensor and calculates according to the rate of heating, controls the intelligent control stopcock to adjust the firepower of the burner component, so that the pot temperature is stabilized at around the set temperature value, thereby realizing automatic temperature control and intelligent cooking.

[0012] Furthermore, when "steaming" or "making soup" of the intelligent mode function file is selected through the "function selection button", the display component displays the corresponding mode and displays the timing time setting value at the same time. The timing time is set by pressing the "+" and "-" buttons of the display component, and the timing time is transmitted to the controller; the controller receives the pot temperature signal fed back by the temperature sensor and calculates according to the rate of heating, and controls the intelligent control stopcock to adjust the firepower of the burner component. When the calculated value of the pot temperature reaches the preset temperature value of the controller, the controller controls the bistable valve in the intelligent control stopcock to adjust the burner component to a low fire, and the controller starts timing. After the timing time reaches the timing time, the controller controls the intelligent control stopcock to perform the fire-off operation, cuts off the gas, and turns off the burner component, thereby realizing automatic timing intelligent cooking.

[0013] Furthermore, when the temperature detected by the temperature sensor exceeds the safety temperature set by the controller, the controller controls the self-priming solenoid valve in the intelligent control plug valve to perform a fire-off operation.

[0014] The smart gas stove provided by the utility model sends different signals after selecting and confirming the corresponding smart mode through the display button. The corresponding signals represent the corresponding functions of the smart mode. The controller sends different instructions according to different signals to realize functions such as fire power level, fixed temperature setting and timing time setting. Compared with previous smart stoves, the knob + button operation is more intuitive and convenient, the cost is greatly reduced, the functions are still complete, and the experience is relatively good.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown, a household gas double stove, the right burner is a general stove, and the left is an intelligent gas stove, including: a display assembly 100, an intelligent control plug valve 200, a controller 300, a temperature sensor 400 and a burner assembly 500. The intelligent control plug valve 200 is a manually operated component, the display assembly 100 can display the working status and perform timing and constant temperature operations, the temperature sensor 400 automatically collects the temperature signal of the pot, the controller 300 collects the electrical signals of the display assembly 100 and the temperature sensor 400 and sends a control signal to the intelligent control plug valve 200 after calculation, the intelligent control plug valve 200 adjusts the on and off of the gas according to the control signal and provides a suitable gas flow to the burner assembly 500, and the burner assembly 500 burns the gas to provide heat to the pot. The controller 300 is connected to a thermocouple, and the head of the thermocouple is located at the edge of the fire hole of the burner assembly 500, which plays an accidental flameout protection function.

[0020] The display assembly 100, the self-priming solenoid valve 202 and the bistable valve 203 of the intelligent control plug valve 200, and the temperature sensor 400 are electrically connected to the controller 300, and the intelligent control plug valve 200 is connected to the gas source and the burner assembly 500; Figure 2 shown.

[0021] like Figure 3 As shown, the intelligent control plug valve 200 includes a plug valve body 201, a valve stem 204, an air intake channel, and a main fire channel and a small fire channel for providing gas to the burner. The air intake channel is equipped with a self-priming solenoid valve 202 that controls the on-off by an electrical signal. The main fire channel is integrated with the plug valve body and is equipped with a bistable valve 203 that controls the on-off. The plug valve body 201 is responsible for inputting the gas source and regulating the gas circuit, the bistable valve 203 is responsible for the on-off control of the main fire gas circuit, the self-priming solenoid valve 202 is responsible for the on-off control of the entire gas circuit, and the valve stem 204 is responsible for adjusting the firepower.

[0022] The hand-push solenoid valve used in the traditional plug valve requires the valve stem to be pressed down to drive the push rod in the valve body to move. The solenoid valve sealing surface can be normally closed after being pushed to a certain stroke, and it cannot be automatically closed to open the gas path. The self-priming solenoid valve 202 used in this technical solution has the same installation structure and external dimensions as the traditional hand-push solenoid valve. By increasing the magnetic force generated by the coil, the solenoid valve can be automatically closed during operation. There is no need to use a push rod to assist, and its closing and closing can be completely controlled by the controller 300. When the pot temperature signal fed back by the temperature sensor 400 exceeds or is about to exceed the set temperature value, the controller 300 controls the self-priming solenoid valve 202 to automatically close; when the pot temperature signal fed back by the temperature sensor 400 is lower than or exceeds the set temperature value, the controller 300 controls the self-priming solenoid valve 202 to automatically open, and controls the igniter to complete the re-ignition action.

[0023] The intelligent mode function gear is divided into at least four gears: healthy stir-frying, frying, steaming, and soup making. When the intelligent gas stove is in working or standby state, the ignition can be completed by rotating the valve stem 204 to the high fire position, and each intelligent mode cooking is realized by turning on and off the bistable valve 203 and the self-priming solenoid valve 202. When the valve stem 204 is rotated to the off position, the air inlet channel of the plug valve body 201 is closed, and the off operation is performed.

[0024] The display assembly 100 includes a “function selection button” for selecting the smart mode gear and a button “+” and a button “-” for setting the temperature or time.

[0025] Embodiment 1, "healthy stir-fry" or "frying" intelligent mode.

[0026] Working principle: ① When the pot temperature fed back by the temperature sensor 400 is about to exceed the set temperature value, the controller 300 controls the bistable valve 203 in the intelligent control plug valve 200 to close the main fire gas path; ② When the pot temperature fed back by the temperature sensor 400 is close to or exceeds the set temperature value, the controller 300 controls the self-priming solenoid valve 202 in the intelligent control plug valve 200 to close the entire gas path; ③ When the pot temperature fed back by the temperature sensor 400 is lower than the set temperature value, the controller 300 controls the bistable valve 203 and the self-priming solenoid valve 202 in the intelligent control plug valve 200 to reopen the entire gas path, and controls the igniter to complete the re-ignition action; the above steps are repeated to realize intelligent constant temperature cooking.

[0027] When the intelligent control stopcock 200 is rotated to the high fire position and the "healthy stir-fry" or "frying" function file of the intelligent mode is selected, the display component 100 displays the corresponding function file and the temperature setting value at the same time. The temperature is set by pressing the "+" and "-" buttons of the display component 100. After the temperature is set, it is transmitted to the controller 300; the controller 300 receives the pot temperature signal fed back by the temperature sensor 400 and calculates according to the heating rate, controls the intelligent control stopcock 200 to output a suitable gas flow rate by switching on and off each gas path, adjusts the firepower of the burner component 500, stabilizes the pot temperature at about the set temperature value, realizes automatic temperature control and intelligent cooking, prevents the food from burning, deteriorating, and producing too many harmful substances during the cooking process, and can also reduce the cooking requirements relative to the differences between different pots and the amount of food.

[0028] Embodiment 2: "steaming" or "making soup" intelligent mode.

[0029] Working principle: When the pot temperature fed back by the temperature sensor 400 reaches 100°C and continues to work until the time set by the system program, the controller 300 controls the bistable valve 203 in the intelligent control plug valve 200 to close the main fire gas circuit, and the cooker continues to use a low fire until the timing time ends. The controller 300 controls the self-priming solenoid valve 202 in the intelligent control plug valve 200 to close the entire gas circuit, thereby realizing intelligent timed cooking.

[0030] When the intelligent control stopcock 200 is rotated to the high fire position and the "steaming" or "soup making" function of the intelligent mode is selected, the display component 100 displays the corresponding function level and the timing time setting value at the same time. The timing time is set by pressing the "+" and "-" buttons of the display component 100, and the timing time is transmitted to the controller 300 after the timing time is completed; the controller 300 first receives the pot temperature signal fed back by the temperature sensor 400 and calculates according to the heating rate, and controls the intelligent control stopcock 200 to output the appropriate gas flow by opening and closing each gas path. , adjust the firepower of the burner assembly 500. When the calculated value of the pot temperature (the calculated value of the pot temperature is close to the temperature of the food in the pot and lower than the real-time temperature of the pot) reaches the preset temperature value (100°C) of the controller 300, the controller 300 controls the intelligent control stopcock 200 to adjust the burner assembly 500 to a low fire, and the display assembly 100 starts timing. After the timing time reaches the timing time, the controller 300 controls the intelligent control stopcock 200 to perform the fire-off operation, cut off the gas, and turn off the burner assembly 500, thereby realizing automatic timing intelligent cooking.

[0031] To prevent the stove from burning dry or abnormally, when the temperature detected by the temperature sensor 400 exceeds the safety temperature set by the controller 300, the controller 300 will control the intelligent control stopcock 200 to perform the fire-off operation, and the safety temperature is set to 280°C.
