Description

Technical Field

[0001] The invention relates to an intelligent control method of an ice cream machine based on discharging frequency. Background Art

[0002] The ice cream machine is a mechatronic product that includes a refrigeration system, a mechanical stirring system and an electrical control system.

[0003] When the ice cream machine in the prior art is turned on, after adding materials, in the automatic control mode or when the refrigeration is manually started, the electrical control system controls the refrigeration system and the stirring system to start. When the refrigeration system continues to refrigerate and cools the liquid ice cream in the freezing cylinder to a semi-solid or fully solid state, the temperature in the evaporation cylinder decreases, and at the same time, the resistance of the stirrer increases when the ice cream changes from liquid to semi-solid or fully solid, resulting in an increase in the current of the stirring motor or a decrease in the speed. At this time, the control system detects the temperature, current or speed to sense whether the ice cream has reached the set molding degree. When it reaches this, the refrigeration system stops, the stirring system stops, and the ice cream machine is in standby mode. In the standby mode, if there is an operation such as manual vending or automatic vending to trigger the discharge switch to make the ice cream machine discharge materials, the stirring system and the refrigeration system will be started again.

[0004] If the ice cream machine does not discharge material, the standby state will last for a certain period of time. The duration of the standby state is generally set by the user in the system of the ice cream machine. The industry generally sets the duration to a fixed 1 minute to 15 minutes. When the set standby time is reached, the refrigeration system of the ice cream machine starts to refrigerate, forming a cycle of standby and refrigeration, which repeats over and over again.

[0005] Due to the different seasons, changes in the flow of people, temperature, weather and demand characteristics, the sales frequency of the ice cream machine during normal working hours is not fixed and often varies greatly. For example, when the flow of people is large, sales are often continuous, and when the flow of people is small or there is no one, there is often a long time or multiple refrigeration cycles without discharging and selling. When there is no sales and the original fixed standby time is still executed, unnecessary refrigeration work cycles will occur. When the sales frequency is high, if the original longer standby time is executed, problems such as soft ice cream or inability to keep up with the discharging capacity will occur. Summary of the invention

[0006] The object of the present invention is to provide an intelligent control method for an ice cream machine based on the discharging frequency, which automatically and intelligently adjusts the standby time by detecting the discharging nodes and the discharging frequency.

[0007] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows:

[0008] An intelligent control method for an ice cream machine based on the discharging frequency is provided, wherein a refrigeration stage in which a refrigeration system of the ice cream machine refrigerates ice cream material to a state ready for sale and a standby stage after the refrigeration stage are recorded as a refrigeration standby cycle.

[0009] When the ice cream machine is turned on and enters normal working state, the duration of the standby stage in the refrigeration standby cycle is set to the initial value T. If the ice cream machine has not discharged material or the discharge amount is less than H in the previous refrigeration standby cycle, the standby stage duration of the subsequent refrigeration standby cycle is greater than T; if the ice cream machine has discharged material and the discharge amount is greater than H in the previous refrigeration standby cycle, the standby stage duration of the subsequent refrigeration standby cycle is less than T; if the ice cream machine has discharged material and the discharge amount is equal to H in the previous refrigeration standby cycle, the standby stage duration of the subsequent refrigeration standby cycle remains at the initial value T.

[0010] The present invention can adjust the duration of the standby stage according to the amount of material discharged in the refrigeration standby cycle. When the material is discharged frequently, the standby time can be shortened, and the newly added ice cream can be quickly refrigerated to avoid the problem of soft material or insufficient discharge capacity when discharging; when the discharge frequency is low, unnecessary refrigeration time can be reduced to reduce energy consumption.

[0011] The present invention also has the following preferred design:

[0012] As a feasible implementation of the present invention,

[0013] If the ice cream machine does not discharge material or the discharge amount is less than H in the previous refrigeration standby cycle, the duration of the standby phase of the subsequent refrigeration standby cycle is automatically set to the initial value T + extension value N;

[0014] If the ice cream machine discharges material in the previous refrigeration standby cycle and the discharge amount is greater than H, the duration of the standby phase of the subsequent refrigeration standby cycle is automatically set to the initial value T-shortening value M.

[0015] Through the above method, it can be realized that the standby time is automatically and intelligently shortened when the material is frequently discharged, and the standby time is automatically and intelligently extended when there is no material discharge or less material discharge.

[0016] The discharge amount of the ice cream machine of the present invention in a refrigeration standby cycle is measured by the number of discharges. The specific number of discharges is preferably determined according to the characteristics of the ice cream machine and the volume of the freezing cylinder of the ice cream machine. For example, the molding characteristics of soft ice cream and hard ice cream are different. The relationship between the change of ice cream molding degree and the number of discharges can be obtained through experiments and calculations, and then a reasonable number of discharges can be set.

[0017] In the present invention, generally: 1 minute ≤ the initial value T ≤ 15 minutes.

[0018] In the present invention, generally: 1 minute ≤ the extension value N ≤ 30 minutes.

[0019] In the present invention, generally: 1 minute ≤ the shortening value M ≤ 15 minutes.

[0020] As another feasible implementation of the present invention:

[0021] When the ice cream machine is turned on and enters the normal working state, the duration of the standby phase in the first refrigeration standby cycle is set to the initial value T. In the two adjacent refrigeration standby cycles, the duration of the standby phase of the previous refrigeration standby cycle is recorded as T. 前 , the duration of the next refrigeration standby cycle is T 后 ,

[0022] If the ice cream machine discharges material in the previous refrigeration standby cycle and the discharge amount is equal to H, then the standby phase duration of the next refrigeration standby cycle is T 后 =T;

[0023] If the ice cream machine does not discharge material or the discharge amount is less than H in the previous refrigeration standby cycle, the standby phase duration of the next refrigeration standby cycle is T 后 =T 前 +T';

[0024] If the ice cream machine discharges material in the previous refrigeration standby cycle and the discharge amount is greater than H, then the standby phase duration of the next refrigeration standby cycle is T 后 =T 前 -T".

[0025] For the convenience of user operation, the discharge amount of the ice cream machine in one refrigeration standby cycle is measured by the number of discharged materials.

[0026] Among them, 1 minute ≤ T' ≤ 30 minutes, 1 minute ≤ T" ≤ 15 minutes.

[0027] In addition, due to the protection of the refrigeration system and the requirement for the maximum melting time of the ice cream, it is necessary to set limits on the minimum and maximum duration of the standby phase.

[0028] The present invention sets a minimum duration T of the standby phase of the refrigeration standby cycle. min , if the calculated duration of any refrigeration standby cycle is less than T min , the duration of the standby phase of the refrigeration standby cycle is automatically set to T min ;

[0029] Set the maximum duration T of the standby phase of the cooling standby cycle max , if the calculated duration of any refrigeration standby cycle is greater than Tmax , the duration of the standby phase of the refrigeration standby cycle is automatically set to T max .

[0030] The present invention has the following beneficial effects:

[0031] The present invention can adjust the duration of the standby stage according to the amount of material discharged in the refrigeration standby cycle. When the material is discharged frequently, the standby time can be shortened, and the newly added ice cream can be quickly refrigerated to avoid the problem of soft material or insufficient discharge capacity during discharge, thereby ensuring the discharge quality of the ice cream; when the discharge frequency is low, unnecessary refrigeration time can be reduced to reduce energy consumption.
