Description

Technical Field

[0001] This invention relates to the field of energy-saving refrigerator technology, and in particular to a flake ice machine and its control method, electronic equipment and storage medium. Background Technology

[0002] In practical commercial scenarios, such as restaurant kitchens and beverage bars, commercial flake ice machines often have their ice dispensing doors permanently open to maximize convenience and high-frequency ice dispensing. This constant openness allows warm, humid air to continuously penetrate the machine, condensing into water on the evaporator's inner walls and in the channels. Consequently, the dispensed flake ice repeatedly melts and condenses due to moisture absorption, eventually forming hardened clumps in the ice dispensing channel or storage compartment. This severely hinders ice dispensing flow, significantly impacting user experience and equipment reliability. Summary of the Invention

[0003] To address the problems of hot and humid air intrusion and condensation on the inner wall leading to continuous melting and freezing of ice flakes in commercial flake ice machines caused by the ice outlet being constantly open, this invention provides a flake ice machine, its control method, electronic equipment, and storage medium.

[0004] To achieve the above-mentioned objectives, the present invention employs the following technical solution: The first aspect of this invention discloses a flake ice machine, comprising: Box; The ice inlet is located at the front of the upper half of the box body; A temperature sensor is located at the ice extraction port to obtain the ambient temperature in real time; A wind deflector is rotatably mounted on top of the ice extraction port; A fan is located on the rear wall inside the housing and within the range corresponding to the ice extraction port; The controller is used to calculate the average rate of temperature change over a continuous preset time based on the ambient temperature transmitted by the temperature sensor, and to control the rotation angle of the wind deflector and the rotation speed of the fan based on the average rate of temperature change.

[0005] According to the flake ice machine, the ice dispensing port is also equipped with a sensor for detecting whether a human body is approaching.

[0006] According to the flake ice machine, the housing is equipped with a stirring device.

[0007] A second aspect of this invention discloses a control method based on the aforementioned flake ice machine, comprising the following steps: Real-time acquisition of the ambient temperature at the ice extraction port; Calculate the average rate of temperature change over a continuous preset time period based on the obtained ambient temperature; The rotation angle of the wind deflector and the rotation speed of the fan are controlled based on the average rate of temperature change.

[0008] According to the control method described above, controlling the rotation angle of the wind deflector and the rotation speed of the fan based on the average temperature change rate specifically includes: If the average rate of temperature change is greater than 0, adjust the angle of the wind deflector to the first angle range and adjust the fan speed to the first speed range. If the average rate of temperature change is 0, adjust the angle of the wind deflector to the second angle range and adjust the fan speed to the second speed range. If the average rate of temperature change is less than 0, adjust the angle of the wind deflector to the third angle range and turn off the fan; Wherein, the minimum value of the first angle interval is greater than or equal to the maximum value of the second angle interval; the minimum value of the second angle interval is greater than or equal to the maximum value of the third angle interval; and the minimum value of the first speed interval is greater than or equal to the maximum value of the second speed interval.

[0009] According to the control method, when the average temperature change rate is less than 0 and the sensor at the ice outlet for detecting whether a human body is approaching does not detect a human body approaching, the stirring device inside the box is activated.

[0010] According to the control method, when the controller obtains that the opening time of the ice dispensing port of the flake ice machine exceeds the preset opening time, and the ice making time exceeds the preset ice making time, and the sensor at the ice dispensing port for detecting whether a human body is approaching does not detect a human body approaching, then the stirring device located inside the box is activated.

[0011] According to the control method, if the sensor at the ice outlet detects a person approaching, the fan will be turned off; otherwise, the rotation angle of the baffle and the rotation speed of the fan will be controlled according to the average temperature change rate.

[0012] A third aspect of the present invention discloses an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the computer program implements the above-described control method when loaded onto the processor.

[0013] A fourth aspect of the present invention discloses a storage medium comprising a stored program, wherein the program, when running, controls the device where the storage medium is located to execute the control method described above.

[0014] Compared with the prior art, the beneficial effects of the present invention include at least the following: This invention calculates the average rate of temperature change over a continuous preset time based on the ambient temperature transmitted by the temperature sensor, and controls the rotation angle of the baffle and the rotation speed of the fan according to the average rate of temperature change, so as to ensure that the inner wall surface is not prone to condensation when the flake ice machine is used with the lid open.

[0023] like Figure 1-2 As shown, Embodiment 1 of the present invention provides a flake ice machine, comprising: Box 1.

[0024] Ice inlet 2 is located on the front side of the upper half of the box body 1.

[0025] Temperature sensor 3 is located at ice outlet 2 and is used to obtain ambient temperature in real time.

[0026] The wind deflector 4 is rotatably mounted on top of the ice outlet 2.

[0027] Fan 5 is located on the rear wall inside the housing 1 and within the range corresponding to the ice outlet 2.

[0028] The controller is used to calculate the average rate of temperature change over a continuous preset time based on the ambient temperature sent by the temperature sensor 3, and to control the rotation angle of the baffle 4 and the rotation speed of the fan 5 based on the average rate of temperature change.

[0029] This invention calculates the average rate of temperature change over a continuous preset time based on the ambient temperature transmitted by the temperature sensor, and controls the rotation angle of the baffle and the rotation speed of the fan according to the average rate of temperature change, so as to ensure that the inner wall surface is not prone to condensation when the flake ice machine is used with the lid open.

[0030] Preferably, but not limitingly, the ice-collecting port 2 is inclined to facilitate the collection of the prepared ice.

[0031] Preferably, but not limitingly, the fan 5 is provided in pairs.

[0032] Preferably, but not limitingly, the ice-collecting port 2 is also provided with a sensor for detecting whether a human body is approaching.

[0033] This invention ensures that the stirrer is not activated when dispensing ice by installing a sensor at the ice dispensing port to detect whether a person is approaching, thus ensuring ice dispensing safety.

[0034] For example, photoelectric sensors or infrared sensors can be used.

[0035] Preferably, but not limitingly, the housing 1 is provided with a stirring device.

[0036] This invention incorporates a stirring device within the container. When the ice-making and lid-opening times are detected to be prolonged, the accumulated ice flakes are stirred, reducing the probability of ice flakes freezing and improving the user experience.

[0037] like Figure 3 As shown, Embodiment 2 of the present invention provides a control method for a flake ice machine, comprising the following steps: Step S210: Obtain the ambient temperature at the ice extraction port 2 in real time.

[0038] Step S220: Calculate the average rate of temperature change over a continuous preset time period based on the acquired ambient temperature.

[0039] Step S230: Control the rotation angle of the baffle 4 and the rotation speed of the fan 5 according to the average temperature change rate.

[0040] Preferably, but not limitingly, controlling the rotation angle of the baffle 4 and the rotation speed of the fan 5 based on the average rate of temperature change specifically includes: If the average temperature change rate is greater than 0, adjust the angle of the wind deflector 4 to the first angle range and adjust the speed of the fan 5 to the first speed range.

[0041] If the average rate of temperature change is 0, adjust the angle of the wind deflector 4 to the second angle range and adjust the speed of the fan 5 to the second speed range.

[0042] If the average temperature change rate is less than 0, adjust the angle of the wind deflector 4 to the third angle range and turn off the fan 5.

[0043] Wherein, the minimum value of the first angle interval is greater than or equal to the maximum value of the second angle interval.

[0044] The minimum value of the second angle interval is greater than or equal to the maximum value of the third angle interval.

[0045] The minimum value of the first speed range is greater than or equal to the maximum value of the second speed range.

[0046] Further preferred, but not limiting, is that when the average rate of temperature change is less than 0 and the sensor at the ice outlet 2 used to detect whether a human body is approaching does not detect a human body approaching, the stirring device located inside the box 1 is activated.

[0047] Preferably, but not limitingly, when the controller detects that the opening time of the ice dispensing port 2 of the flake ice machine exceeds the preset opening time, and the ice making time exceeds the preset ice making time, and the sensor located at the ice dispensing port 2 for detecting whether a human body is approaching does not detect a human body approaching, then the stirring device located in the housing 1 is activated.

[0048] Preferably, but not limitingly, if a sensor located at the ice outlet 2 detects a person approaching, the fan 5 is turned off; otherwise, the rotation angle of the baffle 4 and the rotation speed of the fan 5 are controlled according to the average temperature change rate.

[0049] Embodiment 3 of the present invention provides a preferred embodiment of a control method for a flake ice machine, taking a three-speed fan as an example, including the following steps: Step S310: Obtain the ambient temperature at the ice extraction port 2 in real time.

[0050] Step S320: Calculate the average rate of temperature change over a continuous preset time period based on the acquired ambient temperature.

[0051] Step S330: If the average temperature change rate is greater than 0, it is determined that hot air is entering the chamber 1. The angle α of the baffle plate 4 is adjusted to the range of [60°, 90°] to prevent the hot air from rising directly to the top of the chamber 1. The fan speed of the fan 5 is adjusted to a high speed to blow out the hot air.

[0052] If the average temperature change rate is equal to 0, it is determined that the air temperature at the ice outlet 2 has not changed significantly, but there is still some hot air entering the box 1. At this time, there is a small amount of hot air. Adjust the angle α of the baffle plate 4 to the range of [30°, 60°) and adjust the speed of the fan 5 to the medium speed to reduce the leakage of cold air while maintaining the basic anti-frost effect, with energy saving as the main goal.

[0053] If the average temperature change rate is less than 0, it is determined that no hot air enters the chamber 1 at the ice outlet 2, and there may be a situation of cold air leakage. In this case, the angle α of the baffle 4 is adjusted to the range of [0°, 30°), and the fan 5 is turned off to prevent cold air leakage inside the chamber, relying on natural convection to maintain balance. Preferably, the baffle 4 is in the 0° position.

[0054] When the average temperature change rate is less than 0, and the sensor at the ice outlet 2 used to detect whether a human body is approaching does not detect a human body approaching, the stirring device located inside the box 1 is activated.

[0055] When the controller detects that the opening time of the ice dispensing port 2 of the flake ice machine exceeds the preset opening time, and the ice making time exceeds the preset ice making time, and the sensor at the ice dispensing port 2 for detecting whether a human body is approaching does not detect a human body approaching, then the stirring device located in the housing 1 is activated.

[0056] If the sensor at the ice outlet 2 detects a person approaching, it will turn off the fan 5. Otherwise, it will control the rotation angle of the baffle 4 and the rotation speed of the fan 5 according to the average temperature change rate.
