DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0053] The disclosure below provides many different embodiments or examples to realize the different structures of the present application.

As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0056] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0057] As used in this specification and the appended claims, the term "if" may be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined" or "if [described condition or event] is detected" may be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0058] A smart gas stove is a kitchen gas appliance that combines menu cooking functions. It has a certain number of built-in smart menu options, which can realize timed fire-off function, constant temperature cooking function, and some built-in smart cooking menus, such as steaming, frying, boiling water, cooking noodles, etc.

[0059] At present, the gas regulation methods of smart gas stoves mainly include multiple steady-state valve combination regulation method, motor gas regulation valve regulation method, and gas proportional valve regulation method.

[0060] Among them, a combination of multiple steady-state solenoid valves controls the opening and closing of the valve hole through a combination of multiple steady-state valves to adjust the size of the combustion air intake and the combustion power to achieve the purpose of controlling the temperature of the cookware.

[0061] However, since 3-5 steady-state solenoid valves are needed to control one gas line, the gas regulating valve assembly of the stove is relatively large, complex in structure, and relatively expensive. At the same time, the frequent switching of the steady-state valve leads to high power consumption, which is not conducive to the application and promotion of non-plug-in smart gas stoves.

[0062] The motor gas regulating valve is currently only used for single gas circuit regulation, and only its switching characteristics are used. Since it is necessary to adjust the three states of high fire, low fire and off, the valve body structure is relatively complex, the manufacturing difficulty is relatively high, and the cost is relatively high.

[0063] The gas proportional valve adjusts the valve opening through the solenoid valve. Due to the high power consumption and large size of the solenoid valve, the battery power cannot drive the gas proportional valve to work stably. It is currently only suitable for plug-in gas stoves, integrated stoves and other products, but not non-plug-in gas stoves. In addition, due to its high cost, the product application and promotion are relatively limited.

[0064] In order to solve the above technical problems in the prior art, the present application provides a temperature control method and system based on an electric regulating valve, which can reduce the number of actions of the stepper motor and reduce power consumption.

[0065] See also Figures 1 to 3A temperature control system based on an electric regulating valve 01 provided in the present application includes a heating device 02, an electric regulating valve 01 and a controller 05, wherein the heating device 02 is connected to the electric regulating valve 01, the heating device 02 is used to heat the pot to be processed, the electric regulating valve 01 is electrically connected to the controller 05, and the controller 05 is used to execute the method steps described in any of the following embodiments.

[0066] In some embodiments, the heating device 02 may be a gas stove, a plug-in gas stove, or an integrated stove, and the heating device 02 is provided with a temperature sensor 03 and a burner 04 .

[0067] like Figure 1 As shown, the electric regulating valve 01 can be arranged at the position of the air inlet pipe 07 of the gas stove and electrically connected to the controller 05 (or the operator). The movement of the electric regulating valve 01 is controlled by the MCU of the controller 05, thereby controlling the opening and closing of the valve size of the electric regulating valve 01, thereby controlling the combustion power of the burner 04, and further controlling the temperature of the pot to be processed.

[0068] The electric regulating valve 01 includes a stepping motor 1, a screw rod 2, a slider 3, a diaphragm assembly 4, a valve core assembly 5 and a valve body 7 which are connected in sequence; the valve core assembly 5 is movably connected to the valve body 7.

[0069] In some embodiments, the valve core assembly 5 is provided with a rubber member 8 , the valve body 7 is provided with a boss surface 9 , and the rubber member 8 is movably connected to the boss surface 9 .

[0070] That is, the step angle generated by the rotation of the stepper motor 1 is converted into the linear motion of the screw 2 to control the opening of the valve core assembly 5, thereby realizing the control of the amount of gas intake.

[0071] Specifically, the stepper motor 1 rotates, driving the screw 2 on the motor shaft to rotate, the external thread of the screw 2 cooperates with the internal thread of the slider 3, pushing the slider 3 to move forward (backward), the end of the slider 3 presses against the plastic part of the membrane assembly 4, so that the membrane assembly also moves forward (backward), pushing the valve core assembly forward, the distance between the end face of the rubber part 8 on the valve core assembly 5 and the convex surface 9 of the valve body 7 gradually decreases, the valve opening becomes smaller, and the intake volume decreases. When the rubber part 8 on the valve core assembly 5 is completely in contact with the convex surface 9 of the valve body 7, the intake is cut off and the valve body 7 is closed. When the stepper motor 1 moves in the reverse direction, the slider 3 retreats. At this time, due to the elastic force of the spring 6, the valve core assembly 5 retreats, pushing the membrane assembly 4 backward, the distance between the end face of the rubber part 8 on the valve core assembly 5 and the convex surface 9 of the valve body 7 increases, the valve opening becomes, the intake volume increases, the combustion firepower increases, and the combustion power on the heating device 02 (such as a gas stove) increases. By adjusting the step angle and forward and reverse rotation of the stepper motor 1, the fire power of the heating device 02 (such as a gas stove) can be adjusted. By controlling the stepper motor 1 by the controller, intelligent control of the heating device 02 (such as a gas stove) can be achieved.

[0072] In some embodiments, the electric regulating valve 01 further includes a motor housing 11 , the stepper motor 1 is disposed in the motor housing 11 , and the electric regulating valve 01 is further provided with a seal, which is disposed in a gap between the stepper motor 1 and the motor housing 11 .

[0073] The outer ring 15 of the membrane is located in the groove where the motor housing 11 is connected to the valve body 7 and is locked by screws to achieve sealing to prevent gas leakage.

[0074] The sealing member may include a first rubber pad 12 and a second rubber pad 13 , and the first rubber pad 12 and the second rubber pad 13 are respectively disposed at two ends of the stepping motor 1 , so as to provide double sealing protection and further enhance the sealing performance.

[0075] In addition, the outlet 14 of the stepper motor 1 can be sealed with a sealant, so that the accidental failure of the outer membrane ring 15 can be avoided and gas leakage can be effectively prevented, thereby ensuring the safe use of the gas stove.

[0076] The electric regulating valve 01 provided in the present application has a simple structure, a small size, a strong regulating ability and a low cost, and therefore can facilitate the promotion of smart gas stoves.

[0077] See also Figure 4 , Figure 4 A schematic flow chart of a first embodiment of a temperature control method based on an electric regulating valve provided in the present application.

[0078] See also Figure 4 , the method comprises the following steps:

[0079] Step 110: Obtaining the preset temperature of the cookware to be processed.

[0080] Step 120: Based on the preset temperature, select the first step number corresponding to the preset temperature from a preset temperature-step number curve.

[0081] The preset temperature-step curve can be found in Figure 5 .

[0082] In some embodiments, the entire valve opening process of the stepper motor can be sampled in advance for the entire combustion process. The temperature is collected once every n steps (within the temperature identifiable range, n is as small as possible) of the stepper motor to form a temperature step curve. Figure 5 The preset temperature-step curve is shown.

[0083] Step 130: operate the stepper motor for the first number of times so that the heating device heats the pot to be processed.

[0084] Step 140: Acquire the actual temperature of the heated cookware to be processed.

[0085] Step 150: obtaining a compensation step number based on the actual temperature and the preset temperature, and controlling the stepper motor to run the compensation step number so that the pot to be processed reaches the preset temperature.

[0086] In this embodiment, since the first step corresponding to the preset temperature is selected from the preset temperature-step curve, the stepper motor can be directly operated for the first step, and after obtaining the actual temperature of the pot to be processed after heating, the compensation step is obtained according to the actual temperature and the preset temperature, and then the stepper motor is controlled to operate the compensation step, so that the pot to be processed reaches the preset temperature. In this way, the number of actions of the stepper motor can be reduced, and the power consumption can be reduced.

[0087] In addition, heating equipment (such as gas stoves) are usually powered by built-in batteries. Therefore, reducing the number of times the stepper motor moves can also improve battery life.

[0088] Referring to the second embodiment of a temperature control method based on an electric regulating valve provided in the present application, the method comprises the following steps:

[0089] Step 210: Obtaining the preset temperature of the cookware to be processed.

[0090] Among them, the preset temperature can be 150°C, 160°C, 170°C, 180°C, etc., and can be set manually according to actual conditions. This application does not limit it here.

[0091] Step 220: Based on the preset temperature, select the first step number corresponding to the preset temperature from a preset temperature-step number curve.

[0092] Step 230: operate the stepper motor for the first number of times so that the heating device heats the pot to be processed.

[0093] Step 240: Acquire the actual temperature of the heated cookware to be processed.

[0094] Step 250: obtaining a compensation step number based on the actual temperature and the preset temperature, and controlling the stepper motor to run the compensation step number so that the pot to be processed reaches the preset temperature.

[0095] Exemplarily, for example, the preset temperature T is set to 180°C, and in the preset temperature-step number curve: at 150°C, the number of steps S=100 steps; at 180°C, the number of steps S=200 steps; at 210°C, the number of steps S=300 steps.

[0096] Check the preset temperature-step curve. At 180°C, the first step is S1=200 steps.

[0097] Therefore, the stepper motor runs 200 steps, and the burner in the heating device starts to work and burns, heating the pot to be processed placed on the heating device.

[0098] The temperature sensor in the heating device monitors the temperature change of the pot to be processed in real time. It is assumed that after a period of time, the actual temperature of the pot to be processed after heating is detected to be 170°C.

[0099] Since the actual temperature of 170°C is not equal to the preset temperature of 180°C, it is necessary to re-match the preset temperature-step curve. Assume that in the new temperature-step curve: at 160°C, the number of steps S = 150 steps; at 170°C, the number of steps S = 180 steps; at 180°C, the number of steps S = 200 steps.

[0100] That is, at 170°C, the number of steps S2 = 180 steps.

[0101] According to the first step number at the preset temperature of 180°C and the corresponding second step number at the actual temperature of 170°C, the compensation step number = S0 = S2-S1 = 180-200 = -20 steps can be obtained.

[0102] Since S0 is a negative value, it means that the current number of steps is insufficient and the number of steps needs to be increased to improve firepower.

[0103] That is, the stepper motor needs to run an additional (|S0|=20 steps, that is, move forward 20 steps to increase the firepower, so that the temperature rises further, so that the final temperature of the pot to be processed reaches the preset temperature of 180°C, then stop adjusting, and complete the temperature control.

[0104] In some embodiments, step 250, i.e., obtaining a compensation step number based on the actual temperature and the preset temperature, and controlling the stepper motor to run the compensation step number, includes:

[0105] Step 251: Determine the temperature difference between the actual temperature and the preset temperature.

[0106] Step 252: Determine whether the temperature difference is greater than a preset first temperature value and less than a preset second temperature value.

[0107] Among them, the preset first temperature value can be -5, -6, -7, -8, -9, -10, etc., and the preset second temperature value can be 5, 6, 7, 8, 9, 10, etc., which can be manually set and adjusted according to actual conditions.

[0108] Step 253: If the temperature difference is greater than the preset first temperature value and less than the preset second temperature value, the compensation step number is 0, and the stepper motor does not operate.

[0109] That is, the preset first temperature value Tt<temperature difference △T<preset second temperature value TH. At this time, it can be considered that the actual temperature is approximately equal to the preset temperature. Therefore, the compensation step number S0=0, and the stepper motor does not need to act.

[0110] In some implementations, if the temperature difference is less than a preset first temperature value, the following steps 254 and 255 are performed.

[0111] Step 254: Determine a target temperature, and obtain a first compensation step number based on the target temperature.

[0112] Step 255: Control the stepper motor to reverse the first compensation step number.

[0113] In some implementations, if the temperature difference is greater than a preset second temperature value, the following steps 256 and 257 are performed.

[0114] Step 256: Determine a target temperature, and obtain a second compensation step number based on the target temperature.

[0115] Step 257: Control the stepper motor to rotate forward by the second compensation step number.

[0116] In some embodiments, determining the target temperature comprises:

[0117] 1) Obtain one-half of the temperature difference.

[0118] 2) Adding half of the temperature difference to the preset temperature to obtain the target temperature.

[0119] For details, please refer to the following formula 1:

[0120] T 目 =T+△T / 2, formula 1.

[0121] T 目 is the target temperature, T is the preset temperature, and △T is the temperature difference.

[0122] That is, when the preset first temperature value Tt> the temperature difference △T, it means that the actual temperature is higher than the preset temperature, then according to the target temperature T 目 =T+△T / 2, get the target temperature T 目 The corresponding step value S2 is calculated as the first compensation step number S01=S2-S1, and the stepper motor is controlled to reverse the first compensation step number S01;

[0123] When the temperature difference △T> the preset second temperature value TH, it means that the actual temperature is lower than the preset temperature, then according to the target temperature T 目 =T+△T / 2, get the target temperature T 目 The corresponding step value S3 is used to calculate the second compensation step number S02=S3-S1, and the stepper motor is controlled to rotate forward by the second compensation step number S02 steps.

[0124] In some embodiments, the method further comprises:

[0125] Step 310: Record the adjustment steps of the stepper motor.

[0126] Step 320: Obtain the total number of steps that the stepper motor can run.

[0127] Wherein, step 320 includes step 321 and step 322:

[0128] Step 321: Obtain the total stroke of the electric control valve, the step angle of the stepping motor and the pitch of the screw.

[0129] Among them, the total stroke L of the electric control valve can be Figure 6 shown.

[0130] Step 322: Based on the total stroke of the electric control valve, the step angle and the pitch, the total number of steps that the stepper motor can run is obtained.

[0131] Step 321 and step 322 may refer to the following formula 2:

[0132]

[0133] Among them, S is the total number of steps that the stepper motor can run, L is the total stroke of the electric control valve, θ is the step angle of the stepper motor, and P is the pitch of the screw.

[0134] In some embodiments, in order to ensure the airtightness of the valve, 2 to 5 steps are usually added to the total number of calculated steps to ensure that there is no leakage after the valve is closed.

[0135] Step 330: Obtain a reset step number based on the total step number and the adjustment step number.

[0136] Step 340: Based on the reset step number, the stepper motor is reset to close the electric regulating valve.

[0137] For steps 310 to 340, refer to the following formula 3:

[0138] S 复 =S-(S1+S2+S3+.....Sn), formula 3.

[0139] The number of adjustment steps in the adjustment process is S1, S2...Sn (in the number of steps, clockwise rotation is positive and counterclockwise rotation is negative). 复 When the power is turned off and reset, the remaining steps are the reset steps, and S is the total steps. The specific calculation of S can refer to formula 2.

[0140] That is, when the power is turned off and reset, by controlling the stepper motor to run the remaining steps, i.e. the reset steps, it is possible to avoid running too many steps and causing a waste of electricity, thereby greatly improving the battery life.

The computer program can be stored in a storage medium, which is a computer-readable storage medium. The computer program is executed by at least one processor in the computer system to implement the process steps of the embodiment of the above method.
