Description

Technical Field

[0001] The present invention relates to the technical field of ice making machines, and in particular to an ice making machine with a self-regulating function. Background Art

[0002] As people's living standards improve, ice making has a huge demand in life. For example, in commercial small-scale automatic cold drink machines, ice making devices are often required. At present, there are many ice making devices with different working principles on the market, and the extruder ice maker (i.e., screw ice maker) is more popular. The screw ice maker is a continuous ice making device that makes ice and removes ice at the same time. It is small in size, occupies less space, and is easy to install. It does not require preparation and de-icing time during the entire ice making process, so it is widely popular. The screw ice maker consists of a compressor, a condenser, an evaporator, an ice making cylinder, a screw, an ice cutter, a storage bin, etc. Its working principle is: when the refrigerant passes through the outer wall of the evaporator, it absorbs and takes away the heat of the water in the evaporator, and the water temperature gradually drops to the freezing point to form ice particles. The screw ice scraper in the ice making cylinder rotates under the drive of the motor to transport the ice upward along with the screw. As the ice cubes are continuously squeezed out, a certain flow of cold drinking water controlled by the water inlet valve switch at the bottom of the ice making cylinder is continuously added, and the water is continuously made into ice in this way. The existing screw ice maker is driven by a motor with a reducer, and it is necessary to develop a suitable motor for different models. One of its disadvantages is that the cost of the drive part is relatively high, resulting in high cost and high price of the whole machine;

[0003] Traditional equipment may have the following problems during use:

[0004] 1) Conventional squeeze ice machines are greatly affected by the quality of the water source. When the water hardness or TDS value is too high, the hardness of the ice will increase, which may cause the ice in the evaporator to be unable to be squeezed out. The amount of dissolved matter precipitated in the water increases, causing dirt to form inside the evaporator, affecting the operation of the mechanical parts in the evaporator and the cleanliness of the ice, causing food safety risks;

[0005] 2) Conventional squeeze ice machines are greatly affected by ambient temperature and water source temperature. When the ambient temperature and water source temperature change with the seasons, the normal working state of the ice machine is affected and abnormalities are prone to occur.

[0006] 3) When the amount of ice made in the evaporator changes and the ice making speed and ice extrusion speed do not match, it is easy to cause the extruded ice to have poor quality or the ice to be extruded untimely and freeze to death in the evaporator. Summary of the invention

[0007] The object of the present invention is to provide an ice maker with a self-regulating function.

[0031] In the implementation case, by setting up the TDS sensor 10 for automatic monitoring of water quality, the water source is automatically selected for direct use or for use after filtering by the reverse osmosis water filter 7.

The spraying operation can be realized by the sprayer 16 first, and then the condensing fan 15 can be used to evaporate the water body to improve the heat dissipation efficiency.

[0032] Working principle:

[0033] By setting a temperature sensor to monitor the ambient temperature in real time, the normal operation of the compressor 14 and the condensing fan 15 can be directly controlled by the monitored temperature, so that the startup of the device can be controlled more accurately, and the entire device can be protected and started more completely.

[0034] By setting up the TDS sensor 10 for automatic monitoring of water quality, the water source is automatically selected for direct use or for use after being filtered by the reverse osmosis water filter 7. The water source temperature detected by the water temperature sensor automatically adjusts the water temperature in the water tank 1. The refrigeration pipe 23 and the heating plate 24 are used to start and use together to improve the water temperature adaptability of the device, which can better adapt the ice making efficiency of the device. The condensing fan 15 realizes the cooling operation for the condenser 13, and the sprayer 16 can be used to realize the spraying operation first, and then the condensing fan 15 can be used to evaporate the water body to improve the heat dissipation efficiency;

[0035] (1) Condensing fan adjustment

[0036] The ambient temperature sensor set in the device collects the ambient temperature

[0037] 1) When the ambient temperature is normal, run at medium speed;

[0038] 2) When the ambient temperature is too high, run at high speed;

[0039] 3) When the ambient temperature is too low, run at low speed.

[0040] (2) Water temperature adjustment

[0041] The water temperature sensor installed in the water tank collects the water temperature in the water tank

[0042] 1) When the water temperature is normal, the pipeline between the refrigeration reversing valve and the water tank is closed, the refrigeration solenoid valve is closed, and the refrigerant flows directly from the evaporator to the compressor. The heating plate does not work.

[0043] 2) When the water temperature is low, the pipeline between the refrigeration reversing valve and the water tank remains closed, the refrigeration solenoid valve remains closed, and the refrigerant flows directly from the evaporator to the compressor. When the water temperature is lower than the set temperature limit, the heating plate works to heat the water in the water tank. When the water temperature reaches the set temperature limit, the heating plate stops working.

[0044] 3) When the water temperature is high, the heating plate remains closed. When the water temperature is higher than the set temperature upper limit, the pipeline between the refrigeration reversing valve and the water tank is opened, the refrigeration solenoid valve is opened, and the refrigerant flows from the evaporator through the refrigeration pipe of the water tank first, and then flows to the compressor to cool the water in the water tank. When the water temperature reaches the set temperature lower limit, the pipeline between the refrigeration reversing valve and the water tank is closed, the refrigeration solenoid valve is closed, and the refrigerant flows directly from the evaporator to the compressor.

[0045] (3) Gear motor adjustment

[0046] The ice making capacity of the refrigeration system is logically determined based on parameters such as the ambient temperature sensor, the water temperature sensor in the water tank, the condensing fan speed and the compressor frequency.

[0047] 1) When the logic determines that the ice making capacity of the equipment is normal, the reduction motor runs at normal speed;

[0048] 2) When the logic determines that the cooling capacity of the equipment is insufficient, the reduction motor reduces the speed accordingly based on the data feedback;

[0049] 3) When the logic determines that the cooling capacity of the equipment exceeds the limit, the reduction motor increases the speed accordingly based on the data feedback.

[0050] (4) Water source conversion

[0051] TDS sensor detects the TDS value of water source

[0052] 1) When the TDS value of the water source is lower than the set value, the water source flows directly into the water tank through the reversing valve and the water pump;

[0053] 2) When the TDS value of the water source is higher than the set value, the reversing valve changes the direction of the water path, the solenoid valve opens, and the water source flows through the reversing valve into the reverse osmosis water filter, the solenoid valve, and then into the water tank;

[0054] The compressor 14 is a variable frequency compressor, which can adjust the output of cooling capacity according to the operating status of the machine.
