Description
Technical Field
The invention relates to the technical field of refrigeration, in particular to a semiconductor refrigeration ice cream machine controller, a control method and an ice cream machine.
Background
With the improvement of the living standard of people and the enhancement of personalized consumption concepts, personal and household ice cream machines are gradually entering thousands of households. At present, the individual and household active refrigeration type ice cream machines are basically divided into two types: the main structure of the mechanical compression type and semiconductor refrigeration type comprises a refrigeration host, a stirrer, a control system and the like. The mechanical compression type refrigeration control mode mainly adopts a timing mode, the manufacturing time is set according to the manufacturing material quantity, and the refrigeration host is automatically turned off at a timing. The semiconductor refrigeration mode has the advantages that the correlation degree between the refrigeration effect and the using environment temperature is far higher than that of mechanical compression refrigeration, if a timing mode is adopted, the difference of ice cream making effects under different environments is huge, therefore, the semiconductor refrigeration utilizes the correlation between the torque of a stirring motor of a stirrer and the ice cream making effects, the ice cream making effects are controlled by detecting the working current of the stirring motor and setting a threshold value (an ice cream machine control circuit and an ice cream hardness control method, patent number ZL201410444027. X), and the problem that the correlation degree between the semiconductor refrigeration and the using environment temperature is high (namely, the influence of the environment temperature on the semiconductor refrigeration capacity is large) is basically solved. The method for controlling the threshold current is based on the torque dependence of the ice cream making process and the stirring rod of the stirring motor. The ice cream material temperature is reduced along with the ice cream manufacturing process, the food is gradually sticky and tension is increased, the friction force between the ice cream raw material food and the inner barrel wall of the inner barrel is increased, the torsion moment of the stirring motor of the stirrer (embodied in the current parameter of the stirring motor) is increased, the ice cream manufacturing process can be indirectly perceived through detecting the current of the stirring motor, and the stirring motor is controlled to stop rotating by setting the current threshold value of the stirring motor so as to avoid the damage of the stirring motor due to overlarge resistance, thereby realizing the control of the ice cream manufacturing process. The control mode effectively solves the problem that the manufacturing effect of the semiconductor refrigeration ice cream is affected by the ambient temperature, namely, the manufacturing time is automatically adjusted due to different food materials and different ambient temperatures.
The ice cream manufacturing process is suitable for manufacturing large-capacity food materials based on the friction force between the ice cream food materials and the inner barrel wall by utilizing the torsion of the stirring motor, but when the food material manufacturing amount is small, in the ice cream rear-section manufacturing process, a large amount of food materials are basically gathered to the central part of the stirring rod connected with the stirring motor in the middle of the inner barrel due to low-temperature cold contraction of the food materials, so that gaps are generated between the food materials and the inner barrel wall, the friction force between the food materials and the inner barrel wall is greatly reduced, the torsion of the stirring motor cannot reach or exceed a set threshold value, and the ice cream manufacturing process cannot be terminated even if the ice cream manufacturing is completed. Therefore, the semiconductor refrigeration ice cream manufacturing process controlled by the torque of the stirring motor alone cannot meet the requirements of manufacturing a small amount of food ice cream, and how to realize the control of the semiconductor refrigeration ice cream manufacturing process for manufacturing different food amounts is a problem to be solved in the development of the semiconductor refrigeration ice cream machine at present.

The control principle of the invention is as follows: the temperature sensor laid on the inner barrel wall is utilized to sense the temperature of the barrel wall, the sensing of the temperature of food materials in the barrel is indirectly realized, ice cream making (including refrigeration and stirring) is started, and the cooling speed V of the food materials can be obtained through a timer and a temperature sensing value T According to the cooling speed V under the condition of determining the refrigerating capacity T Can calculate the amount of ice cream food material
Wherein Q is the cooling capacity; c-specific heat of food material; delta T-temperature drop value; m-mass of food material); the temperature reduction speed threshold value is set according to the food amount (a plurality of sections can be set), and different control modes for finishing the manufacturing process are divided based on different threshold values. At a temperature reduction rate V T Less than or equal to the minimum threshold V Tmin (namely, the cooling speed is low), which indicates that the food material is sufficiently manufactured, and the torque of the stirring motor can be adopted to control the end of the manufacturing process; when the cooling speed is greater than the highest threshold V Tmax (i.e. rapid cooling speed) indicates that the amount of food is small, and at this time, a timing control mode is adopted, i.e. according to the set time value t m Based on the starting timing, the set time is reached, the stirring motor is forced to stop rotating no matter how much the torque of the stirring motor is, and the alarm prompts the end of the manufacturing process; when the cooling speed is between the minimum and the maximum threshold values, the timing/torque force distance dual control is adoptedThe mode, namely, firstly, any one of the set threshold values (the timing value or the torque value) is reached, the stirring motor stops rotating, and alarms and prompts are given, so that the intelligent automatic control of the ice cream making process of different amounts of food materials is completed, and the control problem that the ice cream making ending mode controlled by the torque alone cannot realize the making of less food materials is effectively solved. In order to achieve better ice cream making effect, the timing threshold value is a variable value in the timing/torque dual control mode, and the timing threshold value t m And the cooling speed V T In a certain inverse proportion ()>
Where k is the proportionality coefficient, associated with semiconductor refrigeration power, i.e. V T The larger the food amount, the smaller the food amount, the timing threshold t m The smaller; conversely, the cooling speed V T The smaller the food material is, the more the food material is produced, the timing threshold t m The larger the torque distance control is, the more the torque distance control corresponds to the actual ice cream making, so the timing threshold value and the torque distance threshold value are between, the torque distance threshold value is controlled to be the priority, and the timing threshold value is controlled to be the secondary. />
