Technical Field

Background

With the development of electrical appliance control technology and the wide application of various electrical appliances, the requirements for the service performance, the service life and the like of different electrical appliances are increasingly promoted.

For electrical equipment such as an ice maker, water can be delivered to a water valve of the ice maker and stored in a water storage tank, and then pumped to a shunt pipe through a water pump, and the shunt pipe enables the water to uniformly flow to an evaporator cooled by a low-temperature liquid refrigerant. When the water is cooled to the freezing point through the evaporator, the water cooled to the freezing point is solidified and changed into ice, when the ice block reaches the required thickness, the ice block enters an ice-removing state, and high-pressure hot gas discharged by the compressor is guided to the evaporator through the reversing valve to replace low-temperature liquid refrigerant. And the ice blocks are separated from the evaporator through a water film formed between the ice blocks and the evaporator and are stored in the corresponding ice storage tanks, so that the ice making operation is completed.

In the use process of the traditional ice maker, the water quality problem cannot be improved by changing the water source because the traditional ice maker can only support the access of a preset water source, so that a large amount of water scale is generated after the ice maker is used for a long time, the normal operation of the ice maker is influenced, and the ice maker needs to be cleaned.

The manual timing cleaning mode is adopted in the prior art, the accumulation degree of the scale inside the ice maker is not monitored in real time, the accumulated scale cannot be cleaned in time, the cleaning efficiency is low, the influence on the normal stable operation of the ice maker is still caused, and the service life of the ice maker is shortened.

Wherein, because non-contact level sensor, not direct contact liquid can realize detecting the function, have difficult contaminated, be convenient for wash or the advantage of liquid feeding, preferably, adopt non-contact level sensor to detect whether lack of water in ice-making water tank 224.

In one embodiment, as shown in fig. 3, there is provided an ice maker control method, which is described by taking the method as an example applied to the controller in fig. 1, and includes the following steps:

step S302, detecting the running state.

The running state can comprise a normal ice making state, a water shortage state, a full ice state and a protection state, wherein the protection state comprises a device protection state, a temperature limit protection state and the like. The ice making equipment is also provided with a motor, the motor can be a speed reduction motor consisting of a speed reducer and a motor, and the speed reduction motor realizes control of the stirring speed of a stirring shaft of the ice making equipment. And further aiming at the device protection state, the current value of the motor of the ice making equipment can be detected, and whether the detected current value of the motor is larger than a preset current threshold value or not is judged.

And under the condition that the detected current value of the motor is larger than the preset current threshold value, the motor of the ice making equipment is controlled to stop running, the compressor and the cooling fan of the refrigeration equipment are controlled to stop running, and device fault information is displayed, so that the motor burnout caused by protection failure in an abnormal state can be prevented. In case of displaying device fault information, the ice-out switch is in a failure state, and controls an indicator lamp provided at the corresponding ice-out switch to continuously flash and a buzzer to continuously beep for a warning time, which may be 25 to 35 minutes.

Specifically, under the condition that the detected current value of the motor is smaller than the preset current threshold value, the toggle switch state of the waterway equipment is further judged, the water inlet water source type is determined according to the toggle switch state, and whether the water inlet water source type is in the water shortage state or not is judged according to different water inlet water source types. And when the on-off state of the water level float switch is continuously in the second liquid level state within a preset time period, displaying water shortage fault information and determining that the running state is the water shortage state. The duration of the second liquid level state may be 25S to 35S, that is, the operation state is determined to be a water shortage state when the on-off state of the water level float switch in 25S to 35S continues to be the second liquid level state.

Further, under the condition that the on-off state of the water level float switch is the normal liquid level state, the operation state is not the water shortage state, and whether the operation state is the temperature limit protection state needs to be further judged. For the temperature-limited protection state, the internal temperature of the ice maker, preferably the ice making equipment, is detected. And under the condition that the internal temperature is determined to be greater than a first preset temperature threshold value, triggering high-temperature timing operation, and under the condition that the temperature fault condition is determined to be reached according to the timing duration of the high-temperature timing operation, controlling the compressor, the cooling fan and the motor to stop running, and determining that the running state is a temperature-limiting protection state.

Similarly, in the case that the internal temperature is determined to be less than the second preset temperature threshold, the low-temperature timing operation is triggered, and in the case that the temperature fault condition is determined to be reached according to the timing duration of the low-temperature timing operation, the compressor, the cooling fan and the motor are controlled to stop operating, and the operating state is determined to be the temperature-limited protection state. The first preset temperature threshold is larger than the second preset temperature threshold. For example, the first preset temperature threshold may be any value from 45 to 55 ℃, and the second preset temperature threshold may be any value from 4 to 6 ℃. And when the duration time of the internal temperature being greater than the first preset temperature threshold value or the duration time of the internal temperature being less than the second preset temperature threshold value reaches 25 minutes to 35 minutes, the temperature fault condition is determined to be reached.

In one embodiment, for the determination of the water shortage state, the operation state of the ice maker can be determined to be the water shortage state by detecting the operation state of a liquid level sensor inside an ice making water tank of the ice making device and determining that the liquid level sensor is in the trigger state. And under the condition that the liquid level sensor is determined to be in a non-trigger state, the state of a travel switch in an ice storage barrel of the ice making equipment needs to be further detected, and the running state is determined to be a full ice state or a normal ice making state according to the state of the travel switch. The travel switch is one of position switches (or limit switches), and can be used to make the contact act to connect or disconnect the control circuit by the collision of the mechanical moving part, and the mechanical moving part can be preset at different positions to respectively connect or disconnect the circuit to limit the position or travel of the mechanical movement, so that the moving machine can automatically stop, move in reverse, move at variable speed or automatically reciprocate according to a certain position or travel, and the operation state can be further judged by presetting the corresponding relation between the travel switch state and the operation state. For example, if the operating state corresponding to the on state of the travel switch state is set to be the full ice state, and the operating state corresponding to the off state of the travel switch state is set to be the normal ice making state, the operating state can be determined according to the travel switch state.

Wherein the step of detecting a current value of a motor of the ice making apparatus includes: acquiring a preset current detection task, and sending a current query frame according to the preset current detection task; judging whether the communication is normal or not according to the current inquiry frame; when the communication is determined to be normal, determining the detected current value as the current value of the current motor; when the communication is in fault, the fault code is displayed, and the current frame is retransmitted to judge whether the communication is normal.

And step S304, acquiring the type of the water inlet source of the ice maker under the condition that the running state is detected to be the normal ice making state.

Specifically, under the condition that the running state is detected to be in a normal ice making state, the water inlet source type of the ice making machine is determined according to the state of the toggle switch, wherein the water inlet source type comprises a first type water source and a second water source, the first type water source can be barreled water, the second water source can be city water (or tap water), the difference between the first type water source and the second water source is that the water quality is different, a corresponding water pump needs to be triggered when the barreled water is connected, the water in the barreled water is controlled to flow into the water path equipment through the water pump, and the city water does not need to be controlled by triggering the water pump.

And S306, controlling the waterway equipment to execute a corresponding cleaning program according to the type of the water inlet source.

Specifically, the inlet valve and the water pump of the waterway equipment are controlled to be opened and the outlet valve is controlled to be closed under the condition that the type of the inlet water source is a first type of water source, and the inlet valve and the outlet valve of the waterway equipment are controlled to be opened and the outlet valve is controlled to be closed under the condition that the type of the inlet water source is a second type of water source. The water level state of the water level float switch in the water replenishing tank of the waterway equipment is acquired, and the water is drained according to the liquid level state of the water level float switch in the water replenishing tank of the waterway equipment.

Further, under the condition that the liquid level state of the water level float switch is determined to be the first liquid level state, the water inlet valve and the water pump corresponding to the first type of water source are controlled to be closed, the water outlet valve is controlled to be opened, or the water inlet valve and the water outlet valve corresponding to the second type of water source are controlled to be closed, the water outlet valve is controlled to be opened, and the water drainage flag bit is displayed. And under the condition that the liquid level state of the water level float switch after drainage is in a first liquid level state, triggering a first timer corresponding to the duration time of the mark position in drainage, and judging whether the duration time of the mark position in drainage reaches a drainage fault condition or not according to the first timing time of the first timer. And under the condition that the duration time of the mark position in the drainage is determined to reach the drainage fault condition, generating drainage fault information, and under the condition that the duration time of the mark position in the drainage is determined not to reach the drainage fault condition, controlling the closing of a water inlet valve and a water pump and the opening of a water outlet valve corresponding to the first type of water source again, or controlling the closing of a water inlet valve and the opening of a water outlet valve corresponding to the second type of water source, and displaying the drainage mark position.

And the step of controlling the waterway equipment to execute the corresponding cleaning program according to the type of the water inlet source is repeatedly executed, the water inlet valve can be opened again to feed water through repeatedly executing the cleaning program, and the water quantity in the water replenishing tank is ensured to be sufficient while the cleaning function is realized.

And step S308, controlling the refrigeration equipment and the ice-making equipment to operate under the condition that the waterway equipment is detected to finish the cleaning program.

Specifically, under the condition that the waterway equipment is detected to finish the cleaning program, whether the waterway equipment enters a normal ice making state for the first time is judged, and under the condition that the waterway equipment is determined to enter the normal ice making state for the first time, a motor of the ice making equipment is controlled to start running, and a compressor and a cooling fan of the refrigeration equipment are controlled to start running after delaying for a preset time period. And in the case where it is determined that the normal ice making state is not entered for the first time, a switch control command is detected.

The normal ice making state is entered for the first time, and it can be understood that after the ice maker is started every time, the ice maker enters the normal ice making state for the first time, and then a motor, a compressor, a cooling fan and the like of the ice maker are in a state to be started, so that the motor needs to be controlled to be started first, and the compressor and the cooling fan need to be controlled to be started after a preset time period is delayed. On the contrary, if the ice maker normally starts up and is not currently in the normal ice making state for the first time, the compressor, the cooling fan and the motor of the ice maker are normally started up and do not need to be controlled again. And when the normal ice making state is not entered for the first time, detecting whether a switch control instruction is input, and when the switch control instruction is detected, responding to the input switch control instruction to control the ice making equipment to produce ice and/or water. In one embodiment, under the condition that the waterway device is detected to finish a cleaning program and is judged to enter a normal ice making state for the first time, the motor of the ice making device is controlled to start and operate, and after the motor is started and operated for 2 to 4 minutes, the compressor and the cooling fan of the refrigeration device are controlled to start, so that the aim of preventing the refrigeration device from operating firstly to freeze a rotating shaft of the motor of the ice making device is fulfilled, and the risk of motor abrasion is reduced.

In response to the input switch control command, the ice making apparatus is controlled to discharge ice and/or water at step S310.

Specifically, the switch control instruction comprises an ice outlet switch control instruction, a water outlet switch control instruction and an ice water outlet control instruction, the ice outlet switch control instruction is used for indicating ice outlet of the ice making equipment, the water outlet control instruction is used for indicating water outlet of a water pump of the water path equipment, the ice water outlet control instruction is used for indicating ice outlet of an ice making water tank of the ice making equipment and water outlet of the water pump of the water path equipment, and ice water is obtained through combination.

Further, when the switch control instruction is an ice outlet switch control instruction, the ice outlet switch is controlled to be turned on and the ice making equipment is controlled to be ice-out in response to the input ice outlet switch control instruction, and meanwhile, the motor of the ice making equipment is controlled to be turned off after continuously running for a first preset time period. The purpose of controlling the motor of the ice making equipment to continuously operate for the first preset time period and then to be closed is to control the stirring shaft of the ice making equipment to be started, stir ice blocks in the ice storage barrel and provide assistance for the output of the ice blocks from the ice outlet.

Similarly, in response to the input ice outlet switch control instruction, the ice outlet switch is controlled to be closed, and the motor is controlled to be closed after continuously running for a first preset time period. Wherein, control out the ice switch and close, the purpose that closes after the first preset time quantum of control motor continuous operation simultaneously, control ice-making equipment's (mixing) shaft starts, stirs the ice-cube in the ice storage bucket, prevents to freeze together after the ice in the ice storage bucket melts, breaks down when avoiding next time to go out ice.

According to the control method of the ice maker, the running state is detected, the water inlet source type of the ice maker is obtained under the condition that the running state is detected to be the normal ice making state, and then the waterway equipment is controlled to execute the corresponding cleaning program according to the water inlet source type.
