Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, most of the current ice makers generally include a water tank 1, a water dispenser 3, an ice tray 4, an ice-water separator 7, an ice bank 8, and a controller 11; one end of the ice grid 4 is positioned below the water distributor 3, and the other end of the ice grid extends downwards to the upper part of the ice-water separator 7; one end of the ice-water separator 7 is positioned below the ice grid 4, and the other end of the ice-water separator is inclined downwards and extends to the inlet of the ice storage box 8; the water distributor 3 is communicated with the water tank 1 through the water pump 2, the water tank 1 is communicated with the bottom of the ice-water separator 7, and one side of the ice grid 4 is provided with a heater 5 and a refrigerator 6; the ice storage box 8 is internally provided with an ice-full detector 10, the ice tray 4 is provided with a temperature sensor, the water tank 1 is provided with a water level sensor 9, and the controller 11 is electrically connected with the water level sensor 9, the temperature sensor, the ice-full detector 10, the water pump 2, the heater 5 and the refrigerator 6 respectively.
During ice making: the water pump 2 and the refrigerator 6 are sequentially activated, and the water dispenser 3 continuously pumps the water in the water tank 1 through the water pump 2, and at the same time, the water dispenser 3 uniformly distributes the pumped water to the top of the ice tray 4. The water flowing to the ice tray 4 flows down along the surface of the ice tray 4 by its own weight. In the process that water flows along the surface of the ice tray 4, the refrigerator 6 continuously releases cold energy to the water flowing through the ice tray 4, namely, the refrigerator 6 continuously exchanges heat with the water flowing through the ice tray 4, and the cooled water is gradually condensed on the surface of the ice tray 4 to form ice blocks.
When ice is removed: the heater 5 is activated to heat the ice cubes on the ice grid 4. When the outer wall of the ice cube is slightly melted, the ice cube slides into the ice-water separator 7 below the ice tray 4 under the driving of the self gravity. Because the top surface of the ice-water separator 7 is an inclined surface, ice falling on the ice-water separator 7 slides into the ice storage box 8 along the top surface of the ice-water separator 7 under the driving of the self gravity, and water drops carried on the ice can flow into the water tank 1 again through the ice-water separator 7 in the process.
Example 1
The embodiment provides an ice making control method, which comprises the following steps:
s1, after ice making is started, the temperature of the ice tray 4 and the amount of water in the water tank 1 are monitored:
if the temperature of the ice tray 4 is not reduced, the refrigerator 6 or the water pump 2 is in failure, but if the water amount in the water tank 1 is reduced at the moment, the situation that the water pump 2 is in failure can be eliminated, namely, the water pump 2 runs normally and the refrigerator 6 is in failure at the moment, so that the controller 11 sends out a refrigerator failure signal when the temperature of the ice tray 4 is not reduced and the water amount in the water tank 1 is reduced;
if the water quantity in the water tank 1 is not reduced, the water pump 2 is in fault, and at the moment, the controller 11 needs to send a water pump fault signal;
if the temperature of the ice tray 4 is decreased and the water amount in the water tank 1 is decreased by the preset water amount, which indicates that no abnormality occurs in the entire ice making process, the ice removing step may be started, and then step S2 is executed.
In step S1, the temperature of the ice tray 4 and the amount of water in the water tank 1 may be monitored and determined at the same time, or may be detected and determined one by one. The water amount in the water tank 1 can be monitored by using a pressure type water level sensor 9, as shown in fig. 2, the water level sensor 9 includes a housing 9-1, and a flexible pressure conductor 9-2 and a piezoelectric transducer 9-3 disposed in the housing 9-1, wherein one end of the flexible pressure conductor 9-2 extends into the water tank 1, and the other end is electrically connected to a controller 11 through the piezoelectric transducer 9-3.
Therefore, the ice making control method is convenient, accurate and reliable to operate, the working states of the water pump and the refrigerator can be monitored through linkage monitoring of the temperature of the ice tray and the water quantity in the water tank in the ice making stage, and then the equipment with faults can be rapidly and accurately determined when the equipment has faults.
Further, the step of starting the ice-shedding step in step S2 includes the following steps:
the temperature of the ice tray 4 and the falling of ice cubes in the ice storage box 8 are monitored:
if no ice block falls into the ice storage box 8, the heater 5 or the ice-water separator 7 is indicated to be in fault, but if the temperature of the ice grid 4 rises, the situation that the heater 5 is in fault can be eliminated, that is, the heater 5 runs normally and the ice-water separator 7 is in fault, so that when the temperature of the ice grid 4 rises and no ice block falls into the ice storage box 8, a fault signal of the ice-water separator is sent;
if the temperature of the ice tray 4 is not increased, the heater 5 is in failure at the moment, and the controller 11 needs to send out a heater failure signal;
if the temperature of the ice tray 4 rises and ice cubes fall into the ice storage box 8, the fact that the whole ice removing process is not abnormal is indicated, and the heater 5 can be turned off.
It should be noted that the ice full detector 10 can be utilized to monitor the falling of ice cubes in the ice bank 8 in step S2, specifically during the ice-shedding process: if the controller 11 continuously receives the feedback signal of the full ice detector 10, it indicates that no ice block falls into the ice bank 8; if the controller 11 does not continuously receive the feedback signal of the full ice detector 10, it indicates that ice cubes are dropped into the ice bank 8. Of course, like the step S1, the temperature of the ice grid 4 and the feedback signal of the ice-full detector 10 in the ice bank 8 may be detected and determined at the same time in the step S2, or may be detected and determined one by one.
As shown in fig. 3, the following specifically describes the ice making control method by taking as an example that it is determined whether the water amount in the water tank 1 is changed and then it is determined whether the temperature of the ice tray 4 is changed in step S1, and it is determined whether the feedback signal of the full ice detector 10 in the ice bank 8 is received or not in step S2:

S2.4, acquiring a feedback signal of the full ice detector 10 in the ice storage box 8, and skipping to execute the step S2.5; among them, the ice-full detector 10 may employ an infrared sensor or a laser sensor. For example, when the full ice detector 10 is an infrared sensor, a transmitter and a receiver of the infrared sensor may be disposed at opposite sides of the entrance of the ice bank 8, respectively.
S2.5, judging whether the feedback signal is continuously received, wherein at the moment that the ice cubes fall into the ice storage box 8 through the ice-water separator 7, infrared rays emitted by the emitter are shielded by the falling ice cubes, and the receiver cannot receive the infrared rays emitted by the emitter, so that if the controller 11 continuously receives the feedback signal of the infrared sensor, no ice cube falls into the ice storage box 8 at the moment, and the ice-water separator 7 needs to send a fault signal of the ice-water separator 7 when the ice-water separator 7 breaks down; if the controller 11 does not continuously receive the feedback signal of the infrared sensor, it is indicated that the whole deicing process is not abnormal, and the step S2.6 is executed;

And S0.2, judging whether the feedback signal is not continuously received, wherein when the ice storage box 8 is full of ice, the laser emitted by the emitter is shielded by the ice, and the receiver does not receive the laser emitted by the emitter, so that when the controller 11 continuously receives the feedback signal, the step S0.1 can be skipped to execute when the ice storage box 8 is full of ice and the ice making is not required, and otherwise, the step S1 can be skipped to execute when the controller 11 continuously receives the feedback signal, the step S is not completed when the ice storage box 8 is not ice and the ice making is required.
