Description

Technical Field

[0001] The invention belongs to the field of ice making machines, and relates to a water pump failure and water tank water level detection technology, in particular to an ice making machine component and a water pump failure and water tank water level detection method thereof. Background Art

[0002] Most ice machines on the market currently use independent sensors to detect pump failures and water tank water levels. Pump failure detection usually relies on changes in electrical parameters such as current and voltage, while water tank water level detection often uses float switches, water level sensors, etc. Although these detection methods can meet the needs to a certain extent, they have many shortcomings, as shown below:

[0003] First, the pump fault detection method in the prior art is often delayed, and can only be detected when the fault occurs, and no early warning can be given, resulting in a long downtime of the ice machine, affecting production efficiency.

[0004] 2. The accuracy and stability of water tank water level detection are easily affected by factors such as water quality and temperature, and the sensor is easily damaged and has high maintenance costs.

[0005] 3. Most of the detection systems in the prior art have single functions and cannot achieve integrated and intelligent monitoring and control, which increases the cost and complexity of the equipment.

[0006] Therefore, an ice making machine assembly and a method for detecting a pump failure and a water tank water level are needed to solve the above problems. Summary of the invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art; to this end, the present invention proposes an ice machine assembly and a water pump fault and water tank water level detection method thereof, so that the water pump fault detection and early warning can be performed while the water tank water level detection can be completed. Therefore, compared with the traditional two-group independent detection method, the equipment cost and complexity can be effectively reduced, and the purpose of facilitating promotion and application can be achieved. The present invention sets a magnetic induction intensity sensor and a controller, and obtains parameter information by detecting the magnetic induction intensity when the water pump is running. The controller then integrates the parameter information to form data information, and compares the data information with the preset data, so as to judge the abnormality of the water pump and the water tank water level according to the comparison result, so as to realize the function of detecting and early warning of the water pump fault and completing the water tank water level detection at the same time, which can effectively reduce the equipment cost and complexity and facilitate promotion and application.

[0008] To achieve the above-mentioned object, a first aspect of the present invention provides an ice-making machine assembly, comprising a water tank, the water tank being used to contain liquid water to provide a water source for ice making;

[0009] A water pump, the water pump is used to output the water in the water tank to the ice maker to complete the ice making operation;

[0010] A magnetic field strength sensor, which is arranged in the water pump and is used to detect the magnetic field strength of the motor of the water pump during operation and form parameter information;

[0011] A controller, the controller is connected to the magnetic field intensity sensor, receives parameter information output by the magnetic field intensity sensor, integrates the parameter information to form data information, compares the data information with preset data, and determines the water level of the water tank and whether the water pump is abnormal according to the comparison result;

[0012] A display is arranged on the water tank and connected to the controller, and displays lights of different colors or alarms according to the judgment results output by the controller.

[0013] Furthermore, the data information includes the magnetic field strength when the water pump is extracting water from the water tank and the change in the magnetic field strength when the water pump is extracting water from the water tank within a preset time.

[0014] Furthermore, the preset data includes a range of variation of magnetic field intensity within a preset time during a process in which the water pump pumps water from the full water level of the water tank to the empty water level of the water tank.

[0015] Furthermore, the preset data also includes a fourth magnetic field strength recorded by the water pump in an empty pumping state.

[0016] Furthermore, the preset data also includes multiple groups of magnetic field strength ranges when the water pump operates at different water levels in the water tank.

[0017] Further, the plurality of groups of magnetic field strength ranges include a first magnetic field strength range, a second magnetic field strength range, and a third magnetic field strength range;

[0018] The first magnetic field strength range is the magnetic field strength range of the water pump between two-thirds of the water level in the water tank and the full water level;

[0019] The second magnetic field strength range is the magnetic field strength range when the water pump operates between one third and two thirds of the water level in the water tank;

[0020] The third magnetic field strength range is the magnetic field strength range when the water pump operates when the water level in the water tank is between the empty water level and one third of the water level.

[0021] Furthermore, the controller is connected to the water pump. When the controller determines that the water pump is abnormal, it controls the water pump to be powered off and controls the display to alarm.

[0022] On the other hand, the present invention also provides a method for detecting a pump failure and a water tank water level of an ice machine assembly, which specifically comprises the following steps:

[0023] Obtaining the magnetic field strength when the water pump is working and the change in the magnetic field strength range within a preset time during the working period;

[0024] Detect whether the magnetic field strength range within a preset time meets the preset conditions;

[0025] When the magnetic field strength range within the preset time does not meet the preset conditions, the magnetic field strength change range within the preset time is continued to be detected to see if it is 0. If not, it is determined that the water pump is abnormal.

[0026] When the magnetic field strength range within the preset time does not meet the first preset condition and the magnetic field strength change range within the preset time is 0, continue to detect whether the magnetic field strength when the water pump is working is equal to the fourth magnetic field strength when the water pump is running in the empty pumping state. If so, it is determined that the water tank is at an empty water level. If not, it is determined that the water pump is abnormal.

[0027] When the magnetic field strength range within the preset time is detected to meet the preset conditions, the preset magnetic field strength range is compared with the magnetic field strength when the water pump is working to determine the corresponding water tank water level height.

[0028] Furthermore, the preset condition is that the change in magnetic field strength of the water pump within a preset time is within the range of magnetic field strength change within the preset time when the water pump is pumping water from a full water level tank to an empty water level tank.

[0029] Further, the preset magnetic field strength range includes a first magnetic field strength range, a second magnetic field strength range and a third magnetic field strength range;

[0030] When the magnetic field strength of the water pump is within the first magnetic field strength range, it is determined that the water level of the water tank is between two-thirds and the full water level;

[0031] When the magnetic field strength of the water pump is within the second magnetic field strength range, it is determined that the water level of the water tank is between one third and two thirds;

[0032] When the magnetic field strength of the water pump is within the third magnetic field strength range, it is determined that the water level of the water tank is between the empty water level and one third of the water level.

[0033] Compared with the prior art, the present invention has the following beneficial effects:

[0034] By setting up a magnetic induction intensity sensor and a controller, parameter information is obtained by detecting the magnetic induction intensity when the water pump is running. The controller then integrates the parameter information to form data information, and compares the data information with preset data. According to the comparison results, the water pump abnormality and the water tank water level are judged in turn, thereby realizing the function of water tank water level detection while realizing water pump fault detection and early warning, which can effectively reduce equipment cost and complexity and facilitate popularization and application.

[0035] Furthermore, a display is provided, and the display can emit lights of different colors and alarms according to the judgment results, so as to better remind the operator to add water to the water tank or perform troubleshooting operations on the water pump. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1

[0043] See also Figure 1 According to a first aspect of the present invention, an ice making machine assembly is provided, comprising:

[0044] The water tank 1 is used to contain water and provide a water source for ice making.

[0045] The water pump 2 is used to output the water in the water tank 1 to the ice maker to complete the ice making operation.

[0046] A magnetic field strength sensor 3 is provided in the water pump 2 and is used to detect the magnetic field strength of the motor of the water pump 2 during operation and form parameter information.

[0047] The controller 4 is connected to the magnetic field strength sensor 3, receives the parameter information output by the magnetic field strength sensor 3, integrates the parameter information to form data information, compares the data information with preset data, and determines the water level of the water tank 1 and whether the water pump 2 has an abnormality according to the comparison result.

[0048] The display 5 is arranged on the water tank 1 and connected to the controller 4 , and displays lights of different colors or alarms according to the judgment results output by the controller 4 .

[0049] The device is provided with a magnetic induction intensity sensor 3 and a controller 4, and acquires parameter information by detecting the magnetic induction intensity when the water pump 2 is running. The controller 4 then integrates the parameter information to form data information, and compares the data information with preset data, so as to successively complete the judgment of the abnormality of the water pump 2 and the water level height of the water tank 1 according to the comparison result, thereby realizing the function of detecting and warning the fault of the water pump 2 while completing the water level detection of the water tank 1, which can effectively reduce the equipment cost and complexity and facilitate the popularization and application.

[0050] Furthermore, by providing a display 5 , the display 5 can emit lights of different colors and alarms according to the judgment result, so as to better remind the operator to add water to the water tank 1 or perform troubleshooting on the water pump 2 .

[0051] In one example, the data information is further limited to better complete the detection of the failure of the water pump 2 and the water level height based on the data information.

[0052] Specifically, the data information includes the magnetic field strength when the water pump 2 extracts water from the water tank 1 and the change in the magnetic field strength when the water pump 2 extracts water from the water tank 1 within a preset time.

[0053] Among them, the magnetic field strength when the water pump 2 extracts water from the water tank 1 is mainly used to detect the water level height of the water tank 1, and the change in magnetic field strength when the water pump 2 extracts water from the water tank 1 within a preset time is used to detect failure of the water pump 2.

[0054] It should be noted that the preset data includes the range of change of magnetic field strength within a preset time during the process of the water pump 2 pumping water from the water tank 1 at a full water level to the water tank 1 at an empty water level, so as to compare with the change of magnetic field strength when the water pump 2 pumps water from the water tank 1 within the preset time.

[0055] Specifically, when the change in magnetic field intensity when the water pump 2 extracts water from the water tank 1 within the preset time is not in a normal state (that is, the water pump 2 is in the process of extracting water from the full water level tank 1 to the empty water level tank 1), and the magnetic field intensity changes within the preset time, it indicates that the water pump 2 has an abnormality; and when the change in magnetic field intensity when the water pump 2 extracts water from the water tank 1 within the preset time is in a normal state (that is, the water pump 2 is in the process of extracting water from the full water level tank 1 to the empty water level tank 1), and the magnetic field intensity changes within the preset time, it indicates that the water pump 2 is operating normally.

[0056] It should be noted that the preset data also includes the fourth magnetic field strength recorded in the empty pumping state of the water pump 2. Since the magnetic field strength of the water pump 2 does not change in the empty pumping state, that is, the change in the magnetic field strength is 0, in the above-mentioned process of detecting and judging the failure of the water pump 2, it is also necessary to detect whether the change in the magnetic field strength of the water pump 2 within the preset time is 0. If the change in the magnetic field strength is 0, it is necessary to further detect whether its magnetic field strength is equal to the fourth magnetic field strength. If the change in the magnetic field strength is not 0 or the change in the magnetic field strength is 0 but its magnetic field strength is not equal to the fourth magnetic field strength, it is determined that the water pump 2 has a failure.

[0057] Furthermore, based on the premise that the water pump 2 operates normally, the water level height of the water tank 1 can be detected according to the magnetic field strength when the water pump 2 extracts water from the water tank 1 in the subsequent process.

[0058] The preset data also includes multiple groups of magnetic field strength ranges when the water pump 2 operates at different water levels in the water tank 1 .

[0059] Specifically, the multiple groups of magnetic field strength ranges include a first magnetic field strength range, a second magnetic field strength range and a third magnetic field strength range.

[0060] The first magnetic field strength range is the magnetic field strength range of the water pump 2 when the water level of the water tank 1 is between two-thirds and the full water level.

[0061] The second magnetic field strength range is the magnetic field strength range when the water pump 2 operates when the water level height of the water tank 1 is between one third and two thirds.

[0062] The third magnetic field strength range is the magnetic field strength range when the water pump 2 operates when the water level of the water tank 1 is between the empty water level and one third of the water level.

[0063] It should be noted that due to the different loads of the water pump 2 during operation, its magnetic field strength is also different. For example, when the water pump 2 is loaded with a large load, its magnetic field strength is also large, and when the water pump 2 is loaded with a small load, its magnetic field strength is also small. Therefore, based on this principle, this device compares the magnetic field strength range of the water pump 2 under different water level states of the water tank 1, thereby completing the rapid detection of the water level of the water tank 1 and realizing the function of sequentially detecting the fault of the water pump 2 and the water level of the water tank 1. Compared with the independent detection method in the prior art, this device has the function of integrated detection of the fault of the water pump 2 and the water level of the water tank 1, which can effectively reduce the equipment cost and complexity, and is easy to promote and apply.

[0064] In a further embodiment, the controller 4 is also connected to the water pump 2 so that when the water pump 2 fails, it can be shut down and alarmed in time to reduce the damage to the water pump 2 caused by long-term operation due to the failure.

[0065] Specifically, the controller 4 is connected to the water pump 2. When the controller 4 determines that the water pump 2 is abnormal, it controls the water pump 2 to be powered off and controls the display 5 to sound an alarm.

[0066] Embodiment 2

[0067] like Figure 2 and Figure 3 As shown, this embodiment further proposes a method for detecting the failure of the water pump 2 and the water level of the water tank 1 of the ice making machine assembly on the basis of the first embodiment, so as to integrate the functions of detecting the failure of the water pump 2 and the water level height of the water tank 1 into one system, which has stronger applicability, reduces equipment cost, and is conducive to wide promotion and application.

[0068] A method for detecting a failure of a water pump 2 and a water level of a water tank 1 of an ice making machine assembly comprises the following steps:

[0069] Obtaining the magnetic field strength when the water pump 2 is working and the change in the magnetic field strength range within a preset time in the working time period;

[0070] Detect whether the magnetic field strength range within a preset time meets the preset conditions;

[0071] When the magnetic field strength range within the preset time does not meet the preset conditions, the magnetic field strength change range within the preset time is continued to be detected to see if it is 0. If not, it is determined that the water pump 2 is abnormal.

[0072] When the magnetic field strength range within the preset time does not meet the first preset condition and the magnetic field strength variation range within the preset time is 0, continue to detect whether the magnetic field strength when the water pump 2 is working is equal to the fourth magnetic field strength when the water pump 2 is running in the empty pumping state. If so, it is determined that the water tank 1 is at an empty water level. If not, it is determined that the water pump 2 is abnormal.

[0073] When the magnetic field strength range within the preset time is detected to meet the preset conditions, the preset magnetic field strength range is compared with the magnetic field strength when the water pump 2 is working to determine the water level height of the corresponding water tank 1.

[0074] In this embodiment, through the above steps, the functions of detecting the failure of the water pump 2 and the water level height of the water tank 1 can be completed in sequence, that is, the functions of detecting the failure of the water pump 2 and the water level height of the water tank 1 can be integrated into one system, thereby achieving greater applicability, reducing equipment costs, and facilitating wide promotion and application.

[0075] It should be noted that the preset condition is that the change in magnetic field strength of the water pump 2 within the preset time is within the range of magnetic field strength change within the preset time when the water pump 2 is pumping water from the full water level water tank 1 to the empty water level water tank 1. That is, whether the change in magnetic field strength of the water pump 2 within the preset time is within the range of magnetic field strength change when the water pump 2 is running under normal conditions, if not, then further determine whether the change in magnetic field strength is 0, if it is 0, then continue to detect whether its magnetic field strength is equal to the fourth magnetic field strength (that is, the magnetic field strength when the water pump 2 is empty under normal conditions), if it is equal, then determine that the water pump 2 is in an empty pumping state, and accordingly, the water tank 1 is in an empty water level state at this time. If the change in magnetic field strength is not 0 or the change in magnetic field strength is 0 but its magnetic field strength is not equal to the fourth magnetic field strength, then determine that the water pump 2 is in an abnormal state, and an alarm shutdown operation is required.

[0076] In a further embodiment, the preset magnetic field strength range includes a first magnetic field strength range, a second magnetic field strength range and a third magnetic field strength range.

[0077] Among them, when the magnetic field strength of the water pump 2 is within the first magnetic field strength range, the water level height of the water tank 1 is judged to be between two-thirds and the full water level; when the magnetic field strength of the water pump 2 is within the second magnetic field strength range, the water level height of the water tank 1 is judged to be between one-third and two-thirds; correspondingly, when the magnetic field strength of the water pump 2 is within the third magnetic field strength range, the water level height of the water tank 1 is judged to be between the empty water level and one-third.

[0078] In summary, the present application has the functions of integrated pump 2 fault detection and early warning and water tank 1 water level detection, so compared with the traditional two-group independent detection method, it can effectively reduce equipment cost and complexity, and achieve the purpose of facilitating popularization and application.

[0079] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
