[0062] like Figure 1-3 , as shown in 5-6, Figure 1 A schematic diagram of a stove with temperature control function provided by the present invention is shown. Figure 2A schematic diagram of the heating assembly 41 provided by the present invention is shown. Figure 3 FIG. 4 is a schematic diagram showing a heating assembly 41 provided by the present invention. Figure 5 The curve showing the change of pot temperature with cooking time under the existing stove and control method is shown; Figure 6 The graph shows the change curve of the pot temperature with cooking time under the stove and control method provided by the present invention.

[0063] A stove with a temperature control function according to an embodiment of the present invention includes:

[0064] Cooker housing 1;

[0065] The burner 2 is fixed to the interior of the stove housing 1 and is used to heat the pot placed on the burner 2;

[0066] The plug valve is fixed to the stove housing 1, wherein the output end of the plug valve is connected to the gas pipe 3, and the gas pipe 3 is connected to the burner 2 and the plug valve;

[0067] The temperature control device 4 includes a heating component 41, a sensing module 42, and a control component 43. The heating component 41 is fixedly connected to the cooker housing 1 on one side and connected to the gas pipe 3 on the other side for heating the gas in the gas pipe 3. The sensing module 42 is fixedly connected to the burner 2 for sensing the temperature of the cookware. The control component 43 connects the sensing module 42 and the heating component 41.

[0068] The control component 43 receives a signal from the sensing module 42 to determine whether to turn on the heating component 41 so that the temperature of the pot is within the stir-frying temperature range.

[0069] Among them, the stopcock and the burner 2 are both fixed to the stove housing 1, the gas pipe 3 is connected between the stopcock and the burner 2, the temperature control device 4 includes a gas pipe 3 connecting the stopcock and the burner 2, a heating component 41 is connected to the stove housing 1 and the gas pipe 3, and is used to heat the gas in the gas pipe 3, the sensing module 42 is fixed to the burner 2, and is used to sense the temperature of the pot, the control component 43 is connected to the sensing module 42 and the heating component 41, and determines whether to turn on the heating component 41 by receiving the signal of the sensing module 42, so that the temperature of the pot is within the stir-frying temperature range. In this embodiment, , the control component 43 can be a PLC or a control system. Specifically, when the stove is turned on, the control component 43 turns on the heating component 41. When the sensing module 42 detects that the temperature of the pot meets the stir-fry temperature, the control component 43 turns off the heating component 41. At the same time, during the stir-fry process, the sensing module 42 detects the temperature of the pot in real time. When the temperature of the heating component 41 does not meet the stir-fry temperature, the heating component 41 is turned on to heat the gas. The higher the temperature of the gas, the more heat is brought into the burner 2. In this way, the more heat released by the combustion of the gas, the more it can drive the temperature of the bottom of the pot to rise. In this embodiment, the temperature of the pot refers to the temperature of the bottom of the pot, and the stir-fry temperature refers to 120℃~300℃. The stir-fry temperature is determined by the built-in control system of the stove directly obtaining the stir-fry temperature pressed by the user or input. From Figure 5-6 It can be seen that during the stir-frying process, the addition of cooking wine, meat, vegetables, etc. to existing cookers will cause the stir-frying temperature to drop rapidly. However, the present invention can slow down the temperature drop of the cookware and quickly restore the temperature of the cookware. Moreover, after adding meat, the temperature of the cookware can be raised to meet the stir-frying temperature of the meat. The present invention can detect the temperature of the cookware in real time through the sensing module 42, heat the gas through the heating component 41, and adjust the cookware temperature in real time and quickly to reach the stir-frying temperature, thereby shortening the cooking time and improving the user experience.

[0070] In a preferred embodiment of the present invention, the heating assembly 41 comprises:

[0071] A fixing bracket 411 is detachably connected to the cooker housing 1;

[0072] The heater 412 is detachably connected to the fixing bracket 411;

[0073] The heat conducting plate assembly 413 is sleeved on the outer periphery of the gas pipe 3 and is located on one side of the heater 412;

[0074] The fan 414 is fixed to the fixing bracket 411 and is located on the other side of the heater 412.

[0075] The heater 412 is located at the air outlet end of the fan 414 , and the fan 414 blows the heat generated by the heater 412 toward the heat conducting plate assembly 413 to heat the heat conducting plate assembly 413 .

[0076] like Figure 1-3 As shown, the fan 414 and the heat conducting plate assembly 413 are respectively distributed on both sides of the heater 412. The fan 414 can blow the heat generated by the heater 412 to the heat conducting plate assembly 413. The heat conducting plate assembly 413 includes a plurality of heat conducting plates. The heat conducting plates are sleeved on the outer periphery of the gas pipe 3 and can absorb the heat transferred from the heater 412 and transfer the absorbed heat to the gas in the gas pipe 3 to achieve preheating of the gas. Figure 2-3 The fan 414 is located at the upper part of the heater 412, and the heat conducting plate assembly 413 is located at the lower part of the heater 412. This is for illustration only and is not intended to limit the present invention. As long as the fan 414 and the heat conducting plate assembly 413 are respectively distributed on both sides of the heater 412, it will suffice. In this embodiment, the heater (412) is a PTC heater, a heating tube, or a heating wire. Any solution that can quickly generate heat to heat the gas will suffice.

[0077] In a preferred embodiment of the present invention, the heating assembly 41 further comprises:

[0078] The overheat protector 415 is fixed to the fixing bracket 411 and electrically connected to the heater 412 to prevent the gas temperature from exceeding the set temperature;

[0079] A fuse 416 is fixed to the fixing bracket 411 and electrically connected to the overheat protector 415 to prevent the overheat protector 415 from failing;

[0080] The sensing module 42 includes a temperature sensor, which is used to detect the temperature of the bottom of the cookware.

[0081] like Figure 1-3 As shown, the overheat protector 415 and the fuse 416 are both installed on the fixed bracket 411 and electrically connected to the heater 412. When the preheating temperature of the gas reaches the set requirement, the overheat protector 415 disconnects the circuit, and the circuit can be restored when the temperature drops. When the overheat protector 415 fails and the gas temperature rises to a certain temperature, the fuse 416 will disconnect and cannot be restored after disconnection. The thermal protector 415 and the fuse 416 can avoid the burning of the PTC heater 100 due to excessive temperature, thereby reducing unnecessary economic losses.

[0082] In a preferred embodiment of the present invention, the fixing bracket 411 includes:

[0083] A fixed housing 4111 , wherein the heater 412 and the fan 414 are both detachably connected to the fixed housing 4111 ;

[0084] The L-shaped mounting plate 4112 is fixed to the fixed housing 4111 on one side and to the stove housing 1 on the other side. The L-shaped mounting plate 4112 is provided with a mounting hole 41121 for mounting the overheat protector 415 .

[0085] like Figure 1-3 As shown, there are two L-shaped mounting plates 4112, one fixed to each side of the stationary housing 4111. The stationary housing 4111 is fixed to the stove housing 1 via the L-shaped mounting plates 4112. The stationary housing 4111 and the L-shaped mounting plates 4112 are connected in an integrated manner. During installation, only the L-shaped mounting plates 4112 need to be fixed to the stove housing 1, resulting in a simple structure and easy installation. The heater 412 and the fan 414 can be detachably connected to the stationary housing 4111 via bolts, snap-fit ​​connections, etc. The fan 414 and the heat conducting plate assembly 413 are located on either side of the heater 412 to heat the gas.

[0086] In a preferred embodiment of the present invention, a partition is provided inside the fixed housing 4111. The partition is used to divide the fixed housing 4111 into a first chamber for installing the fan 414 and a second chamber for installing the heater 412. The partition is provided with a vent corresponding to the air outlet end of the fan 414.

[0087] The side wall of the first chamber is provided with a first buckle 41111, and the first buckle 41111 is used to confine the fan 414 to the first chamber;

[0088] A second clip 41112 is provided on the side wall of the second chamber, and the second clip 41112 is used to confine the heater 412 to the second chamber.

[0089] There are no less than two first buckles 41111, and they are evenly distributed along the outer periphery of the first cavity;

[0090] There are no less than two second clips 41112, and they are evenly distributed along the periphery of the second cavity.

[0091] The heater 412 includes a heater body and a mounting base for mounting the heater body, and the mounting base is provided with a positioning pin 4121;

[0092] The second chamber is further provided with a guide groove for installing the positioning pin 4121 .

[0093] like Figure 1-3 As shown, in this embodiment, the first chamber and the second chamber are both open cavities, and the side wall of the first chamber away from the partition is provided with a first clamping groove in a direction perpendicular to the partition. Figure 2-3The opening of the first chamber is at the top of the cavity body, and a first snap groove is opened downward from the top of the side wall of the first chamber perpendicular to the partition, and a first snap 41111 is installed in the first installation groove. The first snap 41111 includes a first snap base connected to the first snap groove and a first snap head fixed to the first snap base. The first snap head is used to clamp the fan 414. Once the fan 414 is clamped into the first chamber, the first snap 41111 can restrain the fan 414 and prevent the fan 414 from escaping from the first chamber.

[0094] A second snap-fitting groove is provided on the side wall of the second chamber away from the partition in a direction perpendicular to the partition. Figure 2-3 As shown, the opening of the second chamber is at the bottom of the chamber body, and a second snap groove is opened from the bottom of the side wall of the second chamber in a direction perpendicular to the partition, and the second mounting groove is installed with a second snap 41112, the second snap 41112 includes a second snap base connected to the first snap groove and a second snap head fixed to the second snap base, and the first and second snap heads are used to clamp the heater 412. During installation, the heater 412 only needs to be clamped into the second chamber, and the second snap 41112 can prevent the heater 412 from falling out of the second chamber.

[0095] The width of the first snap-fit ​​groove is greater than the width of the first snap-fit ​​groove 41111, and the width of the second snap-fit ​​groove is greater than the width of the second snap-fit ​​groove 41112. This allows for a certain degree of flexibility when installing the fan 414 and the heater 412, facilitating quick installation and removal of the fan 414 and the heater 412, resulting in a simple and reasonable structure. The groove width refers to the length of the first snap-fit ​​groove or the second snap-fit ​​groove in the left-right direction.

[0096] In addition, there are no less than two first clips 41111 and second clips 41112, which are evenly distributed along the outer periphery of the first chamber and the outer periphery of the second chamber respectively to prevent the fan 414 and the heater 412 from falling off.

[0097] like Figure 2-3 As shown, a guide groove for installing a positioning pin 4121 is also provided on the side wall of the second chamber. During installation, the positioning pin 4121 is inserted into the guide groove to align the heater 412 with the second chamber. The installation is convenient and fast, and the installation and maintenance efficiency is improved.

[0098] In a preferred embodiment of the present invention, the heating component 41 includes:

[0099] A fixing bracket 411 detachably connected to the cooker housing 1 ;

[0100] The heater 412 is detachably connected to the fixing bracket 411;

[0101] The heat conducting plate assembly 413 is sleeved on the outer circumference of the gas delivery pipe 3 and contacts the heater to transfer the heat of the heater 412 to the heat conducting plate assembly 413 .

[0102] Among them, the heater 412 can be a PTC heater, a heating tube or a heating wire, and the heat conducting plate assembly 413 contacts the heater to transfer the heat of the heater 412 to the heat conducting plate assembly 413. During installation, the contact area between the heater 412 and the heat conducting plate assembly 413 is increased to improve heat transfer and thereby improve the heating efficiency of the gas.

[0103] like Figure 4-6 As shown, Figure 4 A logic diagram of the control method of the cooker provided by the present invention is shown. Figure 5 The curve showing the change of pot temperature with cooking time under the existing stove and control method is shown; Figure 6 The graph shows the change curve of the pot temperature with cooking time under the stove and control method provided by the present invention.

[0104] A method for controlling a cooker according to an embodiment of the present invention includes:

[0105] After the cooker is started, the heating component 41 is turned on to heat the gas. When the temperature of the gas reaches the preset heating temperature, the heating component 41 is turned off;

[0106] Select the stir-fry temperature, and use the temperature sensor to detect the temperature of the pot in real time and feed it back to the control component 43;

[0107] The control component 43 compares the temperature of the pot with the selected stir-fry temperature;

[0108] If the temperature of the pot is lower than the stir-frying temperature, the heating component 41 is turned on again to heat the gas; if the temperature of the pot is higher than or equal to the stir-frying temperature, the heating component 41 is kept off.

[0109] After the cooker is turned on, the heating assembly 41 is activated, turning on the heating gas to heat the gas. When the gas temperature reaches a preset heating temperature, the heating assembly 41 is turned off. In this embodiment, the preset heating temperature is 50°C-200°C, and a different preset heating temperature can be selected according to different stir-fry temperatures. When the cooker is turned on, the heating assembly 41 is activated to heat the gas from the heater 412 and bring the heat into the burner 2, rapidly increasing the heat released by the burner 2 and raising the temperature of the pot. When the temperature of the pot rises rapidly, only the heat of the gas itself can be used, and at this time, the heating assembly 41 can be turned off.

[0110] During cooking, especially during stir-frying, the temperature sensor detects the temperature of the pot in real time and feeds it back to the control component. The control component 43 compares the temperature of the pot with the selected stir-frying temperature. If the temperature of the pot is lower than the stir-frying temperature, the heating component 41 is turned on again to heat the gas; if the temperature of the pot is higher than or equal to the stir-frying temperature, the heating component 41 is kept off. Figure 5-6 It can be seen that in the stir-frying process of existing stoves, adding cooking wine, meat, vegetables, etc. will cause the stir-frying temperature to drop rapidly, while the present invention can slow down the temperature drop of the pot and quickly restore the temperature of the pot. Moreover, after adding meat, the temperature of the pot can be increased to meet the temperature for stir-frying meat. Therefore, the present invention detects the temperature of the pot in real time through a temperature sensor, and the control component 43 can adjust the opening or closing of the heating component 41 in real time according to the stir-frying temperature to keep the temperature of the pot within the stir-frying temperature range at all times; in addition, when the user needs to increase the stir-frying temperature during cooking, the heating component 41 can be turned on to heat the gas, so that the heat released by the gas becomes larger, thereby raising the temperature of the pot to the temperature range set by the user. This embodiment can meet the temperature requirements of different cooking processes such as preheating the pot and stir-frying, and can also adjust the temperature state of the pot bottom at any time, quickly complete cooking, and have high cooking quality, thereby improving the user experience.

[0111] In a preferred embodiment of the present invention, the control component 43 obtains a temperature from the temperature sensor every second, wherein the current temperature is T M , the temperature in the next second is T M+1 , the sum of the temperatures for the Nth consecutive 10 seconds is S N , the sum of the temperatures for the N+1th consecutive 10 seconds is S N+1 , if T M+1 -T M ≤3°C, and S N+1 -S N <6°C, the control component 43 starts the heating component 41 to heat the gas.

[0112] If S N+1 -S N ≥6°C, the control component 43 turns off the heating component 41;

[0113] Or, if T M+1 -T M >3°C, the control component 43 turns off the heating component 41;

[0114] Alternatively, when the number of activations of the heating component 41 reaches a set number, the heating component 41 is turned off;

[0115] Alternatively, when the cooktop is turned off, the heating assembly 41 is turned off.

[0116] The number of times the heating component 41 is started is set according to different stir-frying temperatures. When the stir-frying temperature is 100℃~150℃, the number of times the heating component 41 is started is not more than 5~8 times; when the stir-frying temperature is 150℃~200℃, the number of times the heating component 41 is started is not more than 8~10 times; when the stir-frying temperature is 200℃~300℃, the number of times the heating component 41 is started is not more than 10~15 times.

[0117] like Figure 4-6 As shown, the control component 43 obtains a temperature from the temperature sensor every second and compares the difference between any two adjacent seconds in real time. At the same time, it selects the temperature of any continuous 10 seconds and calculates the temperature sum. By comparing the temperature sum of any two adjacent groups, if T M+1 -T M ≤3°C, and S N+1 -S N <6°, the control component 43 starts the heating component 41;

[0118] If S N+1 -S N <≥6ºC, the control component 43 turns off the heating component 41;

[0119] Or, if T M+1 -T M >3°C, the control component 43 turns off the heating component 41;

[0120] In addition, the number of times the heating component 41 is started can be set according to different stir-frying temperatures. For example, when the stir-frying temperature is 100℃~150℃, the number of times the heating component 41 is started is not more than 5~8 times; when the stir-frying temperature is 150℃~200℃, the number of times the heating component 41 is started is not more than 8~10 times; when the stir-frying temperature is 200℃~300℃, the number of times the heating component 41 is started is not more than 10~15 times, so as to avoid multiple rapid starts of the heating component 41 causing the pot temperature to be too high, affecting the food quality.

[0121] Alternatively, when the cooktop is turned off, the heating assembly 41 is turned off.

[0122] In this embodiment, the temperature sensor detects the temperature of the pot in real time. When the temperature difference between two adjacent seconds is less than or equal to 3°C, the heating component 41 can be started at any time. When the cumulative temperature difference of the pot for 10 consecutive seconds is greater than or equal to 6°C, the heating component 41 is turned off. Through the above method, the conditions for starting or shutting down the heating component 41 can be quickly determined to ensure that the temperature of the pot is always maintained in the stir-frying temperature range. Or when the stir-frying temperature needs to be changed, the pot temperature can be quickly increased to meet the user's needs of not stir-frying and improve the user experience.
