Description

Technical Field

[0001] This invention relates to the technical field of cotton candy equipment, and more specifically, to an adaptive power temperature control method for a cotton candy machine. Background Technology

[0002] In the current field of automated cotton candy equipment, existing technology relies on temperature and humidity sensors inside the sugar-making furnace to collect temperature data. After the equipment is turned on, the sugar-making furnace remains in a cooling state until a consumer inserts coins and presses the sugar-making button. Only then does the sugar-making furnace rapidly heat up to produce sugar based on the temperature and humidity data collected by the sensors inside the furnace. However, the temperature and humidity sensors inside the furnace are easily contaminated by splashing sugar, leading to inaccurate data collection or even sensor failure. This causes the sugar-making furnace to fail to heat up and produce sugar, resulting in a fault report. Furthermore, the installation structure of the temperature and humidity sensors increases the complexity of the furnace and also has the problem of delayed heat conduction, leading to temperature control lag. As a result, automated cotton candy equipment frequently shuts down during the sugar-making process.

[0003] Therefore, a method is needed to directly detect the ambient temperature and humidity inside the cotton candy machine to determine the temperature rise of the burner. Summary of the Invention

[0004] In order to overcome the defects of the prior art, the present invention provides an adaptive power temperature control method for a cotton candy machine, which aims to solve the problems in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is: an adaptive power temperature control method for a cotton candy machine, comprising the following steps:

[0006] S1. After powering on, obtain the ambient temperature and humidity parameters inside the cotton candy machine casing, determine the preheating time of the burner head, and preheat the cotton candy burner head through three stages.

[0007] S2. After preheating, the cotton candy machine enters the heat preservation state, and the furnace head motor is in standby low speed state;

[0008] S3. When it is necessary to make marshmallows, when the sugar addition action is detected, the speed of the burner motor is increased to the sugar making speed, the temperature power is increased to 1.5 times the heat preservation power and maintained for the base for 50 seconds, and the action of maintaining the speed of the burner motor is executed simultaneously.

[0009] S4. After finishing the cotton candy making process, increase the speed of the stove motor to 1.3 times the standby low speed and maintain it for 10 seconds before returning to the standby low speed state.

[0010] In the above-mentioned adaptive power temperature control method for a cotton candy machine, the method for preheating the cotton candy burner head in three stages in step S1 is as follows:

[0011] The first stage involves starting the furnace head motor to rotate and rapidly heating the furnace head by calculating the actual output power, which is then maintained for a preset time.

[0012] After the first stage of heating time is reached, the second stage is the constant temperature preheating stage, which calculates the actual output power and gradually heats up within a preset time.

[0013] After the second stage of heating time is reached, the third stage is the pre-standby stage. The pre-standby stage ends after calculating the actual output power and continuing for a preset time, and then the cotton candy machine enters the heat preservation state.

[0014] In the above-mentioned adaptive power temperature control method for a cotton candy machine, the calculation of the actual output power in the first to third stages is based on the acquired ambient temperature and humidity parameters. The judgment method includes: first setting a preset power adjustment coefficient and a preset heating time of 30 seconds, and then judging the actual output power based on the acquired ambient temperature and humidity parameters.

[0015] In the above-mentioned adaptive power temperature control method for a cotton candy machine, the preset power adjustment coefficient is defined by the following function formula:

[0016]

[0017] in,

[0018] K: Power regulation coefficient;

[0019] T: Ambient temperature (°C);

[0020] H: Ambient humidity (%).

[0021] In the aforementioned adaptive power temperature control method for a cotton candy machine, the calculation method for the actual output power determined based on the acquired ambient temperature and humidity parameters is as follows:

[0022] P 实际 =P 基准 *K*A

[0023] in,

[0024] P 实际 Actual output power;

[0025] P 基准 Standby power reference value;

[0026] K: Power regulation coefficient;

[0027] A: The preset power multiple.

[0028] In the above-mentioned adaptive power temperature control method for a cotton candy machine, for every 5 degrees increase or decrease in the detected temperature and humidity, the preset heating time is reduced or increased by 10%.

[0029] In the above-mentioned adaptive power temperature control method for a cotton candy machine, the preset power multiple of the first stage is 1.5 times the standby heating power, the preset power multiple of the second stage is 1.2 times the standby power, and the preset power multiple of the third stage is 1 times the standby power.

[0030] The beneficial effects of this invention are that the ambient temperature and humidity parameters inside the cotton candy machine can be detected by a temperature and humidity sensor, eliminating the need to place the temperature and humidity sensor inside the sugar-making furnace. This allows the ambient temperature and humidity around the furnace to be used as a reference, enabling the equipment to preheat in three stages after startup, thus making more efficient use of the equipment's power and ensuring the sugar-making furnace is in optimal condition. This allows for faster sugar production when consumers insert coins, and prevents the temperature and humidity sensor from coming into contact with the sugar, reducing the failure rate and simplifying the installation structure of the temperature and humidity sensor.

[0031] Figure 1 This is a flowchart of the adaptive power temperature control method of the present invention. Detailed Implementation

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figure 1 An adaptive power temperature control method for a cotton candy machine, as shown, includes the following steps:

[0034] S1. After powering on, obtain the ambient temperature and humidity parameters inside the cotton candy machine casing, determine the preheating time of the burner head, and preheat the cotton candy burner head through three stages.

[0035] S2. After preheating, the cotton candy machine enters the heat preservation state, and the furnace head motor is in standby low speed state;

[0036] S3. When it is necessary to make marshmallows, when the sugar addition action is detected, the speed of the burner motor is increased to the sugar making speed, the temperature power is increased to 1.5 times the heat preservation power and maintained for the base for 50 seconds, and the action of maintaining the speed of the burner motor is executed simultaneously.

[0037] S4. After finishing the cotton candy making process, increase the speed of the stove motor to 1.3 times the standby low speed and maintain it for 10 seconds before returning to the standby low speed state.

[0038] This embodiment can detect the ambient temperature and humidity parameters inside the cotton candy machine's casing using a temperature and humidity sensor, eliminating the need to place the sensor inside the candy-making furnace. This allows the ambient temperature and humidity around the furnace to be used as a reference, enabling the equipment to preheat in three stages after startup. This more effectively utilizes the equipment's power and ensures the candy-making furnace is in optimal condition, allowing for faster candy production when consumers insert coins. Furthermore, the candy-making process avoids contact between the temperature and humidity sensor and the candy, preventing malfunctions or failures caused by contact, thus reducing the failure rate and simplifying the sensor's installation structure.

[0039] The method for preheating the marshmallow burner in step S1 through three stages is as follows:

[0040] The first stage involves starting the burner motor and rapidly heating the burner based on the calculated actual output power for a preset time. After the first stage heating time is reached, the second stage is a constant-temperature preheating stage, where the actual output power is calculated and the temperature is gradually increased within a preset time. After the second stage heating time is reached, the third stage is a pre-standby stage, which is completed after a preset time based on the calculated actual output power, and then the cotton candy machine enters a heat preservation state. This allows the cotton candy burner to gradually increase its temperature in three stages based on the ambient temperature and humidity parameters inside the machine during preheating, making more efficient use of the burner's heating power. This allows the cotton candy burner to quickly reach the optimal temperature before sugar production, unlike traditional cotton candy burners that simultaneously heat the burner from room temperature to high power during sugar production. This can easily cause the sugar to be thrown out before it melts, and the power remains constantly high, making it prone to malfunctions.

[0041] The calculation of actual output power in stages one through three is based on the acquired ambient temperature and humidity parameters. The method involves first setting a preset power adjustment coefficient and a preset heating time of 30 seconds, then determining the actual output power based on the acquired ambient temperature and humidity parameters. By setting a preset power adjustment coefficient, the system can make judgments based on the range of ambient temperature and humidity parameters detected by the temperature and humidity sensor, thereby making more efficient use of the equipment's energy consumption.

[0042] Specifically, the preset power regulation coefficient is given by the following function formula:

[0043]

[0044] in,

[0045] K: Power regulation coefficient;

[0046] T: Ambient temperature (°C);

[0047] H: Ambient humidity (%).

[0048] This function formula allows us to determine the power adjustment coefficient based on the detected ambient temperature and humidity parameters, so that we can calculate the actual output power required for the current environment based on this power adjustment coefficient.

[0049] The method for calculating the linear difference is as follows:

[0050] Suppose there are two points (T1, H1, K1) and (T2, H2, K2), where: (T1, H1, K1) = (15, 40, 1.2), (T2, H2, K2) = (28, 50, 1).

[0051] Interpolation along the T direction:

[0052] Calculate the value of K when H = 40%:

[0053] K 40 (T)=K1+(T-T1) / (T2-T1)*(K2-K1);

[0054] Calculate the value of K when H = 50%:

[0055] K 50 (T)=K+(T-T1) / (T2-T1)*(K2-K1);

[0056] Interpolation along the H direction:

[0057] Using the above results, calculate the final K value:

[0058] K(T,H)=K 40 (T)+(H-H1) / (H2-H1)*[K 50 (T)-K 40 (T)].

[0059] Example calculation is as follows:

[0060] When the detected ambient temperature and humidity parameters are: ambient temperature T = 20℃ and ambient humidity H = 45%,

[0061] Interpolation along the T direction:

[0062] K 40 (20)=1.2+(20-15) / (28-15)*(1-1.21)=1.1231;

[0063] K 50(20)=1.2+(20-15) / (28-15)*(1-1.21)=1.1231;

[0064] Interpolation along the T direction:

[0065] K(20,45)=1.1231+(45-40) / (50-40)*(1.1231-1.1231)=1.1231;

[0066] Therefore, when the ambient temperature T = 20℃ and the ambient humidity H = 45%, the power regulation coefficient K is 1.1231.

[0067] The actual output power, determined based on the acquired ambient temperature and humidity parameters, is calculated as follows: P 实际 =P 基准 *K*A, where P 实际 Actual output power; P 基准 : Standby power reference value; K: Power adjustment coefficient; A: Preset power multiple. Based on the power adjustment coefficient under the current ambient temperature and humidity parameters, the actual output power can be quickly determined.

[0068] It's worth noting that for every 5-degree increase or decrease in detected temperature or humidity, the preset heating time decreases or increases by 10%. This means that the preset heating time is adjusted based on the current detected temperature or humidity, starting from the original 30-second preset time. This allows for adjustments to the device's factory preset time in different regions, making it more adaptable to varying climates.

[0069] It is also worth noting that the preset power multiple for the first stage is 1.5 times the standby heating power, the preset power multiple for the second stage is 1.2 times the standby power, and the preset power multiple for the third stage is 1 times the standby power.

[0070] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
