Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Hereinafter, a water level detecting apparatus of an ice maker, an ice maker and a water level detecting method of an ice maker according to embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a block schematic view of a water level detecting apparatus of an ice maker according to an embodiment of the present invention. As shown in fig. 2, the ice maker includes: the ice making device comprises an ice making mechanism 10, an ice storage bank 20, a cold water tank 30 and a water spraying mechanism 40, wherein the water spraying mechanism 40 is connected to the cold water tank 30 through a water pipeline, and the water spraying mechanism 40 sprays cold water in the cold water tank 30 to the ice making mechanism 40 so as to make ice by the ice making mechanism; as shown in fig. 1, the water level detecting apparatus includes: a water level sensor 100 and a control unit 200.
As shown in fig. 3, the water level sensor 100 includes a detection probe 101, the detection probe 101 extends into the cold water tank 30, and the water level sensor 100 is configured to detect the water level of the cold water tank 30 and generate water level information. As shown in fig. 1, the control unit 200 is connected to the water level sensor 100, and the control unit 200 is configured to determine a water level of the cold water tank 30 according to the water level information, control the ice maker to perform a water replenishing operation when the water level of the cold water tank 30 is lower than a first preset water level, and control the ice maker to stop the water replenishing operation when the water level of the cold water tank 30 is higher than a second preset water level, where the second preset water level is higher than the first preset water level, and the first preset water level and the second preset water level may be preset according to an actual situation.
In the embodiment of the present invention, a water pump is disposed on a water pipe between the water spray mechanism 40 and the cold water tank 30, and the water pump is configured to pump cold water in the cold water tank 30 to the water spray mechanism 40.
Specifically, as shown in fig. 2, the water spray mechanism 40 is connected to the cold water tank 30 through a water pipe on which a water pump is provided, the water pump pumps cold water in the cold water tank 30 to the water spray mechanism 40, and the water spray mechanism 40 sprays the cold water to the ice making mechanism 40 to make ice.
According to an embodiment of the present invention, as shown in fig. 3, a waterproof plug 102 may be further disposed between the detection probe 101 and the body of the water level sensor 100. The water level sensor 100 may be a capacitive water level sensor.
Specifically, the detection probe 101 of a general capacitive water level sensor generally implements water level detection by directly spreading copper on a Printed Circuit Board (PCB), and the water level sensor has a short detection distance and low sensitivity when detecting water level. Since the ice maker needs to preserve heat of the cold water tank 30, the wall of the cold water tank 30 is thick, and the conventional capacitive water level sensor cannot sense the capacitance change at such a thickness, the water level change of the cold water tank 30 cannot be detected by using a common capacitive water level sensor.
According to the invention, the measuring probe 101 of the capacitance type water level sensor 100 is lengthened, so that the measuring probe can directly extend into the cold water tank 30 and can be contacted with cold water in the cold water tank 30, the water level of the cold water tank 30 can be detected by sensing the change of capacitance, water level information is generated, and the water level information is sent to the control unit 200. The control unit 200 receives the water level information, and judges the water level of the cold water tank 30 according to the water level information, if the control unit 200 judges that the water level of the cold water tank 30 is lower than a first preset water level, which indicates that the water level of the cold water tank 30 is lower, at this time, the control unit 200 controls the ice maker to perform water replenishing operation; if the control unit 200 determines that the water level of the cold water tank 30 is higher than the second preset water level, which indicates that the water level of the cold water tank 30 has reached the highest suitable water level, the control unit 200 controls the ice maker to stop the water supplement operation. Therefore, the water level detection device of the ice machine can prevent the phenomenon that the temperature of the ice making mechanism is continuously reduced due to the fact that the water pump of the ice machine idles because the water level in the cold water tank is too low, and further can reduce the failure rate of the ice machine, and the device is simple in structure.
According to an embodiment of the present invention, the control unit 200 also controls the ice maker to perform the water supplement operation by delaying a first preset time when the water level of the cold water tank 30 is lower than a first preset water level, and the control unit 200 controls the ice maker to stop the water supplement operation by delaying a second preset time when the water level of the cold water tank 30 is higher than a second preset water level. The first preset time and the second preset time may be determined according to actual conditions, for example, the first preset time and the second preset time may be 3s to 5 s.
Specifically, when the ice maker is making ice, the liquid level of the cold water tank 30 may fluctuate due to the pumping action of the water pump, and in order to avoid frequent water replenishing operation of the ice maker, when the control unit 200 determines that the water level of the cold water tank 30 is lower than a first preset water level, the control unit 200 controls the ice maker to perform water replenishing operation after delaying for a first preset time; when the control unit 200 determines that the water level of the cold water tank 30 is higher than the second preset water level, the control unit 200 delays the second preset time and then controls the ice maker to stop the water replenishing operation.
According to an embodiment of the present invention, the water level detecting apparatus of the ice maker described above may further include a temperature sensor 300. As shown in fig. 2, the temperature sensor 300 is provided inside the cold water tank 30, and the temperature sensor 300 is connected to the ground of the electric control board of the ice maker, wherein the sensing probe 101 of the water level sensor 100 is connected to the ground through the cold water and the temperature sensor 300.
Specifically, the temperature sensor 300 is disposed inside the cold water tank 30 and connected to a ground line of an electric control board of the ice maker, and since the temperature sensor 300 is a metal housing and is in contact with cold water in the cold water tank 30, the detection probe 101 of the water level sensor 100 may be communicated to the ground line through the cold water and the temperature sensor 300, so that interference may be reduced, and thus detection accuracy and sensitivity of the water level sensor 100 may be improved.
It should be noted that, in the embodiment of the present invention, the control unit 200 is disposed on the electronic control board.
In summary, according to the water level detection device of the ice maker in the embodiment of the invention, the detection probe of the water level sensor extends into the cold water tank to detect the water level of the cold water tank and generate water level information, the control unit judges the water level of the cold water tank according to the water level information, controls the ice maker to perform water replenishing operation when the water level of the cold water tank is lower than a first preset water level, and controls the ice maker to stop water replenishing operation when the water level of the cold water tank is higher than a second preset water level, so that the phenomenon that a water pump of the ice maker idles due to the fact that the water level in the cold water tank is too low can be prevented, the failure rate of the ice maker can be reduced, the device is simple in structure, and meanwhile, the detection probe of the water level sensor is communicated with the ground wire through cold water and the temperature sensor, so that interference can be reduced, and the detection accuracy and sensitivity of the water level sensor can be improved.
The embodiment of the invention also provides an ice machine, which comprises the water level detection device of the ice machine.

and S1, detecting the water level of the cold water tank through a water level sensor of which a detection probe is extended to reach deep inside the cold water tank and generating water level information.

Specifically, the measuring probe of the capacitive water level sensor is lengthened, so that the measuring probe can directly extend into the cold water tank and can contact cold water in the cold water tank, and therefore the water level of the cold water tank can be detected by sensing the change of capacitance and water level information can be generated. Then, the water level of the cold water tank is judged according to the water level information, if the water level of the cold water tank is judged to be lower than a first preset water level through control judgment, the water level of the cold water tank is indicated to be lower, and at the moment, the ice maker is controlled to carry out water replenishing operation; and if the water level of the cold water tank is judged to be higher than the second preset water level, the water level of the cold water tank is shown to reach the highest proper water level, and the ice maker is controlled to stop water replenishing operation. Therefore, the water level detection method can prevent the phenomenon that the water pump of the ice machine idles due to the fact that the water level in the cold water tank is too low, and further can reduce the failure rate of the ice machine.
According to an embodiment of the invention, when the water level of the cold water tank is lower than a first preset water level, the first preset time is delayed to control the ice maker to carry out water replenishing operation; and when the water level of the cold water tank is higher than the second preset water level, delaying the second preset time to control the ice maker to stop water replenishing operation.
