Description

TECHNICAL FIELD

[0001] The utility model belongs to ice making equipment technical field, concretely relates to an ice maker. BACKGROUND

[0002] The ice maker is a refrigeration mechanical equipment that generates ice by cooling water through an evaporator by refrigerant, adopts a refrigeration system, and generates ice by a certain equipment under the electrified state with water carrier.

[0003] The working principle of the refrigeration system of the existing commercial ice maker is mainly to absorb heat in the evaporator by the refrigerant to realize the ice making process, and the refrigerant releases a large amount of heat in the cooler and other components in this process.

[0004] In the prior art, there are two common heat dissipation methods. One is to dissipate heat by using a heat dissipation fan, which uses the fan to forcibly flow air to take away the heat generated by the refrigeration system. However, this heat dissipation method has obvious defects. Since the specific heat capacity of air is relatively small, the heat dissipation fan cannot effectively dissipate a large amount of heat in actual operation. When the ice maker is in high-load operation, the heat dissipation fan often cannot dissipate heat in time and effectively, which leads to an increase in the temperature of the refrigeration system, and further affects the ice making efficiency and stability of the ice maker, and even may shorten the service life of the ice maker.

[0005] Another heat dissipation method is water cooling. Water cooling is to take away the heat of the refrigeration system by using water as a cooling medium. This method has relatively good heat dissipation effect because the specific heat capacity of water is large and can absorb more heat. However, the water cooling method also has problems. When the ice maker is in a state of completing ice making and does not need to continue to dissipate heat, if the water cooling system is not closed in time, it will cause waste of water resources. In addition, during the water cooling process, the control valve is a key component for controlling water flow. When the control valve is damaged, even if the controller issues a closing instruction, the control valve cannot normally execute the closing action, which causes the cooling water to continue to flow, resulting in waste of water resources. However, the current ice maker lacks effective means for detecting the state of the control valve, and cannot timely detect the abnormal situation that the control valve is damaged but does not execute the closing instruction.

[0006] In summary, it is urgent to provide an ice maker that can close the heat dissipation system in time when heat dissipation is not needed, can monitor the pipeline flow, can alarm in time when the inflow of cooling medium is not closed in time, can avoid waste of cooling medium (water resources), and can reduce maintenance cost. UTILITY MODEL CONTENTS

[0007] The utility model discloses a ice maker which can close the heat dissipation system in time when not needing heat dissipation, can monitor the pipeline flow, can alarm in time when not closing the inflow of cooling material in time, can avoid the waste of cooling material (water resource), and can reduce the maintenance cost.

[0008] The above object is achieved by the following technical scheme: an ice maker, comprising an ice making chamber, the ice making chamber is provided with an ice making mechanism, a heat dissipation mechanism and a controller, the ice making mechanism is used for making ice blocks, the heat dissipation mechanism is used for dissipating heat for the ice making mechanism, the heat dissipation mechanism comprises a heat exchanger, an electric control valve and a flow meter, the electric control valve and the flow meter are in communication connection with the controller, the electric control valve is used for connecting cooling material to the heat exchanger through a pipeline, the flow meter is used for detecting the flow of the cooling material connected to the heat exchanger and sending the detection result to the controller, and the controller is used for controlling the start and stop of the electric control valve and controlling the flow alarm under a predetermined condition.

The flow meter is used for detecting the flow of the cooling material connected to the heat exchanger in real time. The predetermined condition can be set as follows: when the ice making mechanism is in a non-working state, when the flow of the cooling material is greater than 1 L / min for 10 seconds continuously, an alarm is triggered, that is, the controller flow alarm. In this way, the ice maker completes the ice making task and enters a standby state, if the control valve fails to stop the water flow according to the instruction, the flow meter detects the abnormal flow and triggers an alarm, so that water resource waste caused by continuous water flow is avoided; from the operation convenience and safety, the feedback alarm system enables the operator to not need to keep an eye on the equipment at all times, and the work burden is reduced. When the alarm rings, the ice maker operation interface synchronously displays abnormal information, the worker can quickly locate the fault position and reason, and timely measures are taken.

[0010] In specific application, when the cooling material is water flow, the water flow pushes the flow meter turbine blade to rotate when the cooling water flows through the flow meter, the rotation speed of the turbine blade can be calculated to calculate the flow of the water flow, the working indicator light beside the flow meter interface terminal represents the speed of the turbine blade rotation, when the flow of the cooling water is greater than 1 L / min for 10 seconds continuously, a cooling water leakage alarm is triggered.

[0011] Further, the input end of the flow meter is connected with the electric control valve, and the output end of the flow meter is connected with the heat exchanger. When the cooling substance is water flow, the real-time flow of the water flow after the electric control valve is opened can be accurately monitored, and the abnormal flow data can be captured in time once the electric control valve fails to be closed. The output end is connected with the heat exchanger, so that the water flow monitored by the flow meter can enter the heat exchanger normally to exchange heat, thereby realizing effective heat dissipation. The connection can not only discover the water flow anomaly in time and feed back an alarm to avoid waste of water resources, but also can ensure normal operation of the water cooling system and improve stability and reliability of the ice maker.

[0012] Further, the ice maker is provided with a display, the display is in communication connection with the controller, and the controller controls the display to display a flow alarm under a predetermined condition. In this way, the display and the controller of the ice maker are in communication connection and display the flow alarm, so that the operator can intuitively and quickly obtain the abnormal information of the water cooling system.

Specifically, the display is a liquid crystal display panel, the flow alarm display flashes a non-fault icon, and a fault code is displayed on a digital tube.

[0013] Further, the ice maker is provided with a sound alarm, the sound alarm is in communication connection with the controller, and the controller controls the sound alarm to respond to the flow alarm under a predetermined condition. In this way, the operator can be attracted in a more direct way. Even if the operator is in a remote position or does not pay attention to the display, the alarm sound can quickly remind the operator that the flow of the ice maker water cooling system is abnormal, thereby avoiding problems such as waste of water resources and damage to equipment due to negligence and speeding up the response speed of the fault. The sound alarm can be preferably a buzzer, and the buzzer alarms with a 1Hz drop sound.

[0014] Further, the pipeline for accessing the cooling substance to the heat exchanger is provided with a water inlet manual valve. In this way, when the cooling water leakage alarm occurs, the user can close the cooling water inlet manual valve or faucet in time to prevent waste of water resources and economic loss.
