Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of ice maker, in particular to an ice maker automatic control water inlet and outlet ball control method. BACKGROUND

[0002] The ice maker is a refrigeration mechanical equipment which generates ice by cooling water through evaporator by refrigerant. The ice maker adopts refrigeration system and water carrier to generate ice under the condition of power on. According to the principle and production mode of the evaporator, the shape of the generated ice is different. People generally divide the ice maker into granular ice maker, flake ice maker, plate ice maker, tube ice maker and shell ice maker according to the shape of the ice.

[0003] The existing ice making process is to inject a proper amount of liquid water into the water tank, pre-cool to a certain extent, and then deliver the liquid water to the evaporator through the water pump. Under the action of the refrigerant medium, the liquid water is solidified to form ice blocks, and then the ice blocks are removed to be sent to the ice storage box for storage. The water quantity in the water tank of the current ice maker is controlled by the water inlet and outlet ball during the ice making process, but it cannot be determined whether the ice blocks in the ice storage box are full. Therefore, during the ice making process, the ice blocks in the ice storage box are full, but the ice maker still makes ice, which causes the ice blocks to overflow the ice storage box, affects the ice making effect of the ice maker, and even damages the ice maker. SUMMARY

[0004] Therefore, the present application provides an ice maker automatic control water inlet and outlet ball control method to meet the industrial needs.

[0005] An ice maker automatic control water inlet and outlet ball control method comprises the following steps:

[0006] Step S100: providing an ice maker, which comprises an input signal unit and an output signal unit. The input signal unit comprises a water level ball valve accommodated in a water tank and an ice full switch arranged in an ice storage box. The output signal unit comprises a heat valve for ice removal and defrosting, a compressor for providing refrigerant gas, and a water pump and a water inlet valve connected to the water tank.

[0007] Step S110: starting the ice maker to drive the heat valve to run.

[0008] Step S120: when the heat valve runs to the set time, the heat valve continues to run, and the compressor and the water inlet valve are opened.

[0009] Step S130: when the compressor and the water inlet valve run to the set time, the ice full switch in the input signal unit detects the ice full signal. When the ice full switch detects the ice full signal, the output signal unit is closed. When the ice full switch does not detect the ice full signal, the output signal unit continues to run.

[0010] Step S140: When the ice full switch does not detect the ice full signal, the water pump in the output signal unit is turned on, and the compressor and the hot valve and the water inlet valve continue to run;

[0011] Step S150: After the water pump runs for a set time, the hot valve and the water inlet valve are closed, and the compressor and the water pump continue to run;

[0012] Step S160: After the hot valve and the water inlet valve are closed, the water level float valve in the input signal unit is opened to detect the water level;

[0013] Step S170: When the water level detected by the water level float valve is lower than the set water level, the compressor and the water pump run for a set time, and then the ice maker re-executes step S120.

[0014] Further, in step S120, the hot valve runs for a set time of 30 seconds.

[0015] Further, in step S130, the compressor and the water inlet valve run for a set time of 4 minutes.

[0016] Further, in step S150, the water pump runs for a set time of 30 seconds.

[0017] Further, in step S170, the compressor and the water pump run for a set time of 10 seconds.

[0018] Compared with existing technologies, the automatic control method for inlet and outlet float valves in an ice maker provided by this invention provides an ice maker including an input signal unit and an output signal unit. The input signal unit includes a water level float valve housed in a water tank and an ice full switch located in an ice tank. The output signal unit includes a hot valve for defrosting and removing ice, a compressor for providing refrigerant gas, and a water pump and an inlet valve connected to the water tank. When the ice maker is started, the hot valve is driven to operate. After the hot valve has operated for a set time, it continues to operate, and the compressor and the inlet valve are opened. With the compressor and inlet valve open, and the hot valve running for a certain period, the ice full signal in the input signal unit detects the operation. When the ice is full, the switch is activated. When the ice full switch detects a full ice signal, the output signal unit shuts down. When the full ice switch does not detect a full ice signal, the output signal unit operates. After the full ice switch does not detect a full ice signal, the water pump in the output signal unit starts, the compressor starts, and the thermostatic valve and the water inlet valve continue to operate. After the water pump runs for a set time, the thermostatic valve and the water inlet valve close, while the compressor and the water pump continue to operate. After the thermostatic valve and the water inlet valve close, the water level float valve in the input signal unit opens to detect the water level. When the water level signal detected by the water level float valve is lower than the set water level, the compressor and the water pump run for another set period of time, and then the ice maker restarts the thermostatic valve, the compressor, and the water inlet valve. This automatic control method for the inlet and outlet of the ice maker prevents excessive ice in the ice storage box, makes the control during the ice-making process intelligent, reduces energy consumption, and improves the automation level of ice making.

[0019] Figure 1 This is a schematic diagram of the automatic control method for the inlet and outlet floats of an ice maker provided by the present invention. Detailed Implementation

[0020] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.

[0021] like Figure 1 The diagram shown is a flowchart of the automatic control method for the inlet and outlet float of an ice maker provided by the present invention. The automatic control method for the inlet and outlet float of an ice maker includes the following steps:

[0022] Step S100: providing an ice maker, the ice maker comprising an input signal unit and an output signal unit, the input signal unit comprising a water level float ball valve accommodated in a water tank, an ice full switch arranged in an ice storage box, the output signal unit comprising a hot valve for defrosting and ice dropping, a compressor for providing refrigerant gas, and a water pump and a water inlet valve connected to the water tank;

[0023] Step S110: starting the ice maker to drive the hot valve to run;

[0024] Step S120: when the hot valve runs to a set time, the hot valve continues to run, and the compressor and the water inlet valve are turned on;

[0025] Step S130: after the compressor and the water inlet valve run to a set time, the ice full switch in the input signal unit detects an ice full signal, when the ice full switch detects the ice full signal, the output signal unit is turned off, and when the ice full switch does not detect the ice full signal, the output signal unit runs;

[0026] Step S140: after the ice full switch does not detect the ice full signal, the water pump in the output signal unit is turned on, and the compressor, the hot valve, and the water inlet valve continue to run;

[0027] Step S150: after the water pump runs to a set time, the hot valve and the water inlet valve are turned off, and the compressor and the water pump continue to run;

[0028] Step S160: after the hot valve and the water inlet valve are turned off, the water level float ball valve in the input signal unit is turned on to detect the water level;

[0029] Step S170: when the water level signal detected by the water level float ball valve is lower than a set water level, the compressor and the water pump run for a set time again, and then the ice maker re-executes step S120.

[0030] In step S110, the hot valve is turned on to realize defrosting in the ice maker, so as to ensure the ice making effect of the ice maker.

[0031] In step S120, the hot valve continues to run, and the compressor and the water inlet valve are turned on, that is, the ice maker is continuously defrosted, refrigerant gas is provided, and the water tank is filled with water, and in step S120, the hot valve runs to a set time of 30 seconds.

[0032] In step S130, it is judged whether the ice storage box is full of ice, if the ice storage box is full of ice, the ice maker is turned off, if the ice storage box is not full of ice, the subsequent steps are run, and in step S130, the compressor and the water inlet valve run to a set time of 4 minutes.

[0033] In step S140, the water pump is turned on to deliver liquid water into the evaporator, which is frozen into ice cubes under the action of the refrigerant medium.

[0034] In step S150, the water pump is operated for a set time of 30 seconds, and the hot valve and the water inlet valve are both closed. The hot valve is closed to avoid affecting ice making of the ice maker. The water inlet valve is closed to stop water injection into the water tank, so as to keep the water amount in the water tank constant. The water level float valve is used to control the water amount, thereby controlling the ice making amount.

[0035] In steps S160 and S170, the water level float valve is used to detect the water level in the water tank. When the water level signal detected by the water level float valve is lower than the set water level, the compressor and the water pump are operated for a set time, and then the ice maker re-executes step S120, i.e., the hot valve, the compressor, and the water inlet valve are turned on to realize defrosting in the ice maker and water injection into the water tank. It is judged through step S130 whether the ice storage box is full of ice. If the ice storage box is full of ice, the ice maker is closed. If the ice storage box is not full of ice, the ice maker is operated in a loop along the subsequent steps. In step S170, the compressor and the water pump are operated for a set time of 10 seconds. That is, after the water level signal detected by the water level float valve is lower than the set water level, the ice maker continues ice making for 10 seconds.

[0036] Compared with the prior art, the ice maker automatic control water inlet and outlet ball control method provided by the application provides an ice maker, which comprises an input signal unit and an output signal unit. The input signal unit comprises a water level ball valve accommodated in a water tank and an ice full switch arranged in an ice tank. The output signal unit comprises a hot valve for ice dropping and defrosting, a compressor for providing refrigerant gas, and a water pump and a water inlet valve connected to the water tank. The ice maker is started to drive the hot valve to run. When the hot valve runs to a set time, the hot valve continues to run, and the compressor and the water inlet valve are turned on. The compressor and the water inlet valve are turned on, and the hot valve keeps running for a certain time. The ice full switch in the input signal unit detects an ice full signal. When the ice full switch detects the ice full signal, the output signal unit is turned off. When the ice full switch does not detect the ice full signal, the output signal unit runs. When the ice full switch does not detect the ice full signal, the water pump in the output signal unit is turned on, and the compressor is turned on. The hot valve and the water inlet valve continue to run. When the water pump runs to a set time, the hot valve and the water inlet valve are turned off, and the compressor and the water pump continue to run. When the hot valve and the water inlet valve are turned off, the water level ball valve in the input signal unit is turned on to detect the water level. When the water level signal detected by the water level ball valve is lower than a set water level, the compressor and the water pump run for a set time again, and then the ice maker is restarted to run the hot valve, the compressor, and the water inlet valve. The ice maker automatic control water inlet and outlet ball control method avoids ice blockage in the ice storage box, makes the control intelligent during the ice making process, reduces energy loss, and improves the degree of ice making automation.
