As shown in FIG. 2, the ice maker includes: an ice making mechanism 10, an ice storage 20, a cold water tank 30, and a water spray mechanism 40. The water spray mechanism 40 is connected to the cold water tank 30 through a water pipe, and the water spray mechanism 40 The cold water tank 30 is sprayed with cold water to the ice making mechanism 40 for the ice making mechanism to perform ice making; as shown in FIG. 1, the water level detecting device includes: a water level sensor 100 and a control unit 200.
其中，如图3所示，水位传感器100包括检测探头101，检测探头101延长深入至冷水箱30的内部，水位传感器100用以检测冷水箱30的水位并生成水位信息。如图1所示，控制单元200与水位传感器100相连，控制单元200用以根据水位信息判断冷水箱30的水位的高低，并在冷水箱30的水位低于第一预设水位时控制制冰机进行补水操作，以及在冷水箱30的水位高于第二预设水位时控制制冰机停止补水操作，其中，第二预设水位大于第一预设水位，第一预设水位和第二预设水位可以根据实际情况进行预设。As shown in FIG. 3, the water level sensor 100 includes a detection probe 101 that extends deep into the interior of the cold water tank 30. The water level sensor 100 is used 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. The control unit 200 is configured to determine the level of the water level of the cold water tank 30 according to the water level information, and control the ice making when the water level of the cold water tank 30 is lower than the first preset water level. The machine performs a water replenishing operation, and controls the ice machine to stop the water replenishing operation when the water level of the cold water tank 30 is higher than the second preset water level, wherein the second preset water level is greater than the first preset water level, the first preset water level and the second The preset water level can be preset according to the actual situation.
在本发明实施例中，喷水机构40与冷水箱30之间的水路管上设置水泵，水泵用于将冷水箱30中的冷水泵送至喷水机构40。In the embodiment of the present invention, a water pump is disposed on the water pipe between the water spray mechanism 40 and the cold water tank 30, and the water pump is used to send the cold water pump in the cold water tank 30 to the water spray mechanism 40.
具体地，如图2所示，喷水机构40通过水路管连接到冷水箱30，水路管上设置水泵，水泵将冷水箱30中的冷水泵送至喷水机构40，喷水机构40再将冷水喷射到制冰机构40以进行制冰。Specifically, as shown in FIG. 2, the water spray mechanism 40 is connected to the cold water tank 30 through a water pipe, and a water pump is disposed on the water pipe, and the water pump sends the cold water pump in the cold water tank 30 to the water spray mechanism 40, and the water spray mechanism 40 Cold water is sprayed to the ice making mechanism 40 to perform ice making.
根据本发明的一个实施例，如图3所示，检测探头101与水位传感器100的本体之间还可以设置有防水塞102。水位传感器100可以为电容式水位传感器。According to an embodiment of the present invention, as shown in FIG. 3, a waterproof plug 102 may be disposed between the detecting probe 101 and the body of the water level sensor 100. The water level sensor 100 can be a capacitive water level sensor.
具体地，一般的电容式水位传感器的检测探头101一般是直接通过在PCB(Printed Circuit Board，印制电路板)上铺铜实现水位检测的，该类水位传感器检测水位时检测距离近、灵敏度低。由于制冰机需要对冷水箱30做保温处理，冷水箱30的壁较厚，传统的电容式水位传感器无法感知这种厚度下的电容变化，因此采用一般的电容式水位传感器无法检测出冷水箱30的水位变化。Specifically, the detection probe 101 of a general capacitive water level sensor generally directly detects water level by copper plating on a PCB (Printed Circuit Board). The water level sensor detects a water level and has a low detection distance and low sensitivity. . Since the ice machine needs to heat-treat 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 under such thickness, so the cold water tank cannot be detected by the general capacitive water level sensor. 30 water level changes.
本发明通过将电容式水位传感器100的测量探头101加长，使其可以直接伸入至冷水
箱30的内部，并可以接触到冷水箱30中的冷水，从而可以通过感知电容的变化检测冷水箱30的水位并生成水位信息，并将水位信息发送至控制单元200。控制单元200接收水位信息，并根据水位信息判断冷水箱30的水位的高低，如果控制单元200判断冷水箱30的水位低于第一预设水位，说明冷水箱30的水位较低，此时，控制单元200控制制冰机进行补水操作；如果控制单元200判断冷水箱30的水位高于第二预设水位，说明冷水箱30的水位已到达最高合适水位，此时控制单元200控制制冰机停止补水操作。由此，上述的制冰机的水位检测装置可以防止出现由于冷水箱中的水位过低导致制冰机的水泵空转，制冰机构温度持续降低的现象，进而可以降低制冰机的故障率，且该装置结构简单。The invention lengthens the measuring probe 101 of the capacitive water level sensor 100 so that it can directly extend into the cold water
The inside of the tank 30 and the cold water in the cold water tank 30 can be contacted, so that the water level of the cold water tank 30 can be detected by sensing the change in capacitance and water level information can be generated, and the water level information can be transmitted to the control unit 200. The control unit 200 receives the water level information, and determines the level of the water level of the cold water tank 30 according to the water level information. If the control unit 200 determines that the water level of the cold water tank 30 is lower than the first preset water level, the water level of the cold water tank 30 is low. The control unit 200 controls the ice maker to perform the 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, the water level of the cold water tank 30 has reached the highest suitable water level, and the control unit 200 controls the ice maker at this time. Stop the hydration operation. Therefore, the water level detecting device of the ice making machine can prevent the water pump of the ice machine from idling due to the water level in the cold water tank being too low, and the temperature of the ice making mechanism is continuously lowered, thereby reducing the failure rate of the ice making machine. And the device has a simple structure.
根据本发明的一个实施例，在冷水箱30的水位低于第一预设水位时，控制单元200还延迟第一预设时间控制制冰机进行补水操作，并在冷水箱30的水位高于第二预设水位时，控制单元200延迟第二预设时间控制制冰机停止补水操作。其中，第一预设时间和第二预设时间可以根据实际情况，例如，第一预设时间和第二预设时间可以为3s-5s。According to an embodiment of the present invention, when the water level of the cold water tank 30 is lower than the first preset water level, the control unit 200 further delays the first preset time to control the ice making machine to perform the water replenishing operation, and the water level in the cold water tank 30 is higher than When the second preset water level is reached, the control unit 200 delays the second preset time to control the ice maker to stop the water replenishing operation. The first preset time and the second preset time may be according to actual conditions. For example, the first preset time and the second preset time may be 3s-5s.
具体地，制冰机在制冰时，由于水泵的抽水作用会使冷水箱30的液面产生波动，为避免制冰机的频繁进行补水操作，在控制单元200判断冷水箱30的水位低于第一预设水位时，控制单元200延迟第一预设时间后再控制制冰机进行补水操作；在控制单元200判断冷水箱30的水位高于第二预设水位时，控制单元200延迟第二预设时间后再控制制冰机停止补水操作。Specifically, when the ice making machine is making ice, the liquid level of the cold water tank 30 may fluctuate due to the pumping action of the water pump. In order to avoid the frequent water replenishing operation of the ice making machine, the control unit 200 determines that the water level of the cold water tank 30 is lower than When the first preset water level is reached, the control unit 200 delays the first preset time and then controls the ice maker to perform the water replenishing operation; 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 first After the preset time, the ice machine is controlled to stop the water replenishment operation.
根据本发明的一个实施例，上述的制冰机的水位检测装置还可以包括温度传感器300。如图2所示，温度传感器300设置在冷水箱30的内部，且温度传感器300连接制冰机的电控板的地线，其中，水位传感器100的检测探头101通过冷水和温度传感器300连通到地线。According to an embodiment of the present invention, the water level detecting device of the ice maker described above may further include a temperature sensor 300. As shown in FIG. 2, the temperature sensor 300 is disposed 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 detecting probe 101 of the water level sensor 100 is connected to the cold water and temperature sensor 300 to Ground wire.
具体地，温度传感器300设置在冷水箱30的内部且连接制冰机的电控板的地线，由于温度传感器300为金属外壳且与冷水箱30内的冷水接触，因此水位传感器100的检测探头101可以通过冷水和温度传感器300连通到地线，从而可以降低干扰，进而提高水位传感器100的检测精度和灵敏度。Specifically, the temperature sensor 300 is disposed inside the cold water tank 30 and connected to the ground of the electric control board of the ice maker. Since the temperature sensor 300 is a metal outer casing and is in contact with the cold water in the cold water tank 30, the detection probe of the water level sensor 100 The 101 can be connected to the ground through the cold water and temperature sensor 300, so that the interference can be reduced, thereby improving the detection accuracy and sensitivity of the water level sensor 100.
需要说明的是，在本发明实施例中，控制单元200设置在电控板上。It should be noted that, in the embodiment of the present invention, the control unit 200 is disposed on the electronic control board.
综上所述，根据本发明实施例的制冰机的水位检测装置，水位传感器的检测探头深入至冷水箱的内部以检测冷水箱的水位并生成水位信息，控制单元根据水位信息判断冷水箱的水位的高低，并在冷水箱的水位低于第一预设水位时控制制冰机进行补水操作，以及冷水箱的水位高于第二预设水位时控制制冰机停止补水操作，从而可以防止出现由于冷水箱中的水位过低导致制冰机的水泵空转的现象，进而可以降低制冰机的故障率，且该装置结构简单，同时，水位传感器的检测探头通过冷水和温度传感器连通到地线，从而可以降低
干扰，进而提高水位传感器的检测精度和灵敏度。In summary, according to the water level detecting device of the ice maker according to the embodiment of the present invention, the detecting probe of the water level sensor penetrates into the inside of the cold water tank to detect the water level of the cold water tank and generate water level information, and the control unit judges the cold water tank according to the water level information. The level of the water level is controlled, and when the water level of the cold water tank is lower than the first preset water level, the ice making machine is controlled to perform the water supply operation, and when the water level of the cold water tank is higher than the second preset water level, the ice machine is controlled to stop the water supply operation, thereby preventing The phenomenon that the water pump of the ice machine is idling due to the low water level in the cold water tank can reduce the failure rate of the ice machine, and the structure of the device is simple. At the same time, the detection probe of the water level sensor is connected to the ground through the cold water and the temperature sensor. Line, which can be lowered
Interference, thereby improving the detection accuracy and sensitivity of the water level sensor.

The water level is too low, which causes the water pump of the ice machine to idling, which can reduce the failure rate of the ice machine, and its structure is simple.

Wherein, as shown in FIG. 2, the ice making machine comprises: an ice making mechanism, an ice storage tank, a cold water tank and a water spraying mechanism, the water spraying mechanism is connected to the cold water tank through a water pipe, and the water spraying mechanism sprays the cold water of the cold water tank to the ice making machine. The mechanism allows the ice making mechanism to perform ice making; as shown in FIG. 4, the water level detecting method of the ice making machine includes the following steps:
S1，通过水位传感器检测冷水箱的水位并生成水位信息，其中，水位传感器的检测探头延长以深入至冷水箱的内部。S1, the water level sensor detects the water level of the cold water tank and generates water level information, wherein the detection probe of the water level sensor is extended to penetrate into the inside of the cold water tank.
具体地，如图3所示，检测探头与水位传感器的本体之间还可以设置有防水塞。水位传感器可以为电容式水位传感器。Specifically, as shown in FIG. 3, a waterproof plug may be disposed between the detecting probe and the body of the water level sensor. The water level sensor can be a capacitive water level sensor.
S2，根据水位信息判断冷水箱的水位的高低。S2, judging the level of the water level of the cold water tank according to the water level information.
S3，当冷水箱的水位低于第一预设水位时，控制制冰机进行补水操作。S3, when the water level of the cold water tank is lower than the first preset water level, the ice maker is controlled to perform the water filling operation.
S4，当冷水箱的水位高于第二预设水位时，控制制冰机停止补水操作，其中，第二预设水位大于第一预设水位，第一预设水位和第二预设水位可以根据实际情况进行预设。S4, when the water level of the cold water tank is higher than the second preset water level, controlling the ice machine to stop the water filling operation, wherein the second preset water level is greater than the first preset water level, and the first preset water level and the second preset water level may Preset according to the actual situation.
具体地，将电容式水位传感器的测量探头加长，使其可以直接伸入至冷水箱的内部，并可以接触到冷水箱中的冷水，从而可以通过感知电容的变化检测冷水箱的水位并生成水位信息。然后，根据水位信息判断冷水箱的水位的高低，如果控判断冷水箱的水位低于第一预设水位，说明冷水箱的水位较低，此时控制制冰机进行补水操作；如果判断冷水箱的水位高于第二预设水位，说明冷水箱的水位已到达最高合适水位，此时控制制冰机停止补水操作。由此，上述的水位检测方法可以防止出现由于冷水箱中的水位过低导致制冰机的水泵空转的现象，进而可以降低制冰机的故障率。Specifically, the measuring probe of the capacitive water level sensor is lengthened so that it can directly extend into the inside of the cold water tank, and can contact the cold water in the cold water tank, so that the water level of the cold water tank can be detected and the water level can be generated by sensing the change of the capacitance. information. Then, according to the water level information, the water level of the cold water tank is judged. If the water level of the cold water tank is lower than the first preset water level, the water level of the cold water tank is lower, and the ice making machine is controlled to perform the water filling operation; The water level is higher than the second preset water level, indicating that the water level of the cold water tank has reached the highest suitable water level, and at this time, the ice maker is controlled to stop the water supply operation. Therefore, the above-described water level detecting method can prevent the phenomenon that the water pump of the ice maker is idling due to the low water level in the cold water tank, thereby reducing the failure rate of the ice maker.
根据本发明的一个实施例，其中，在冷水箱的水位低于第一预设水位时，还延迟第一预设时间控制制冰机进行补水操作；在冷水箱的水位高于第二预设水位时，还延迟第二预设时间控制制冰机停止补水操作。According to an embodiment of the present invention, when the water level of the cold water tank is lower than the first preset water level, the first preset time is controlled to control the ice making machine to perform the water filling operation; the water level in the cold water tank is higher than the second preset. At the water level, the second preset time is also delayed to control the ice machine to stop the hydration operation.
具体地，制冰机在制冰时，由于水泵的抽水作用会使冷水箱的液面产生波动，为避免制冰机的频繁进行补水操作，在判断冷水箱的水位低于第一预设水位时，延迟第一预设时间后再控制制冰机进行补水操作；在判断冷水箱的水位高于第二预设水位时，延迟第二预
