[0040] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] It is understood that although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims or the above drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0042] The seafood machine is mainly used for cooling and heating seafood pools and fish tanks. It is a water temperature control system that keeps the temperature of seafood pools and fish tanks in a constant state to ensure the normal growth of aquatic organisms. In related technologies, a single seafood machine can generally only control the temperature of a single water tank. Therefore, how to control the temperature of two water tanks through a single seafood machine has become an urgent problem to be solved.

[0043] Based on this, the embodiment of the present application provides a seafood machine, a control method, a device and a medium. By obtaining the initial state of the four-way valve, it can be determined whether the four-way valve is in the heating mode or the cooling mode, and by obtaining the first average water temperature of the first water tank and the second average water temperature of the second water tank, it can be determined whether the water tank needs to be cooled or heated. After determining whether it is currently in the heating mode or the cooling mode through the initial state of the four-way valve, the operating state of the four-way valve and the compressor is controlled according to the control target calculation result and the initial state, which can effectively avoid erroneous heating and cooling. Therefore, through the embodiment of the present application, a single seafood machine can control the temperature of two water tanks.

[0044] Reference Figure 1 , Figure 1 It is a structural schematic diagram of the seafood machine of the present application.

[0045] It can be understood that the seafood machine includes a first heat exchanger, a second heat exchanger, a compressor, a four-way valve, a first water circulation pipe, an electronic expansion valve and a second water circulation pipe. The first end of the four-way valve is connected to the exhaust port of the compressor, the second end of the four-way valve is connected to one end of the first heat exchanger, the third end of the four-way valve is connected to the intake port of the compressor, the fourth end of the four-way valve is connected to one end of the second heat exchanger, the electronic expansion valve is arranged between the first heat exchanger and the second heat exchanger, the first water circulation pipe is used to transport the water in the first water tank to the first heat exchanger for heat exchange, and the second water circulation pipe is used to transport the water in the second water tank to the second heat exchanger for heat exchange.

[0046] It should be noted that the first water circulation system includes a first water pump, a first water inlet, a first heat exchange pipe and a first water outlet, the first water inlet and the first water outlet are respectively arranged at the two ends of the first heat exchange pipe, the first water inlet and the first water outlet are both located in the first water tank, the first water pump is used to pump the water in the first water tank from the first water inlet into the first heat exchange pipe and then flow back to the first water tank from the first water outlet, wherein the first heat exchange pipe can be wound around the first heat exchanger. The second water circulation system includes a second water pump, a second water inlet, a second heat exchange pipe and a second water outlet, the second water inlet and the second water outlet are respectively arranged at the two ends of the second heat exchange pipe, the second water inlet and the second water outlet are both located in the second water tank, the second water pump is used to pump the water in the second water tank from the second water inlet into the second heat exchange pipe and then flow back to the second water tank from the second water outlet, wherein the second heat exchange pipe can be wound around the first heat exchanger.

[0047] It should be noted that, in cooling mode, the first heat exchanger is an evaporator and the second heat exchanger is a condenser; in heating mode, the first heat exchanger is a condenser and the second heat exchanger is an evaporator.

[0048] refer to Figure 2 , Figure 2is a flow chart of a seafood machine control method provided in an embodiment of the present application. The flow chart of the seafood machine control method can be applied to Figure 1 The seafood machine shown in the flowchart of the seafood machine control method includes but is not limited to the following steps:

[0049] Step S100, obtaining a first average water temperature of the first water tank, a second average water temperature of the second water tank, and an initial state of the four-way valve within a first time period;

[0050] Step S200, calculating the difference between the first average water temperature and the preset first target temperature and the difference between the second average water temperature and the preset second target temperature to obtain a target calculation result;

[0051] Step S300: When the target calculation result satisfies the first preset condition, the operating states of the four-way valve and the compressor are controlled according to the initial state and the target calculation result.

[0052] It is understandable that in actual use, if a temperature sensor is used to obtain the water temperature of the first water tank and the second water tank, when aquatic organisms are close to the temperature sensor, the temperature judgment may be affected. Therefore, the first average water temperature can be the average water temperature of the first water tank in the first time period, and the second average water temperature can be the average water temperature of the second water tank in the first time period. By obtaining the first average water temperature and the second average water temperature in the first time period, and then making subsequent judgments, by obtaining the initial state of the four-way valve, it can be determined whether the seafood machine is currently in heating mode or cooling mode. The first target temperature is the required constant water temperature of the first water tank, and the second target temperature is the required constant water temperature of the second water tank. If the first average water temperature is greater than the first target temperature, it means that the temperature in the first water tank has increased, and if the first average water temperature is less than the first target temperature, it means that the temperature in the first water tank has decreased. If the second average water temperature is greater than the second target temperature, it means that the temperature in the second water tank has increased, and if the second average water temperature is less than the second target temperature, it means that the temperature in the second water tank has decreased. The target calculation result includes the difference between the first average water temperature and the preset first target temperature and the difference between the second average water temperature and the preset second target temperature. In some embodiments, the first preset condition may be that the difference between the first average water temperature and the preset first target temperature is greater than the upper limit of the preset temperature difference interval and the difference between the second average water temperature and the preset second target temperature is greater than the upper limit of the preset temperature difference interval or the difference between the first average water temperature and the preset first target temperature is less than the lower limit of the preset temperature difference interval and the difference between the second average water temperature and the preset second target temperature is less than the lower limit of the preset temperature difference interval. By controlling the operating state of the four-way valve and the compressor through the initial state and the target calculation result, the accuracy of the control can be effectively improved. For example, if the target calculation result satisfies the first preset condition and the target calculation result is that the difference between the first average water temperature and the preset first target temperature is less than the lower limit of the preset temperature difference interval and the difference between the second average water temperature and the preset second target temperature is less than the lower limit of the preset temperature difference interval, it means that the water temperature is low and the water temperature in the water tank needs to be heated. If the initial state of the four-way valve is the heating mode at this time, there is no need to adjust the four-way valve, and only the compressor needs to be started. For another example, the target calculation result satisfies the first preset condition, and the difference between the first average water temperature of the target calculation result and the preset first target temperature is greater than the upper limit of the preset temperature difference interval, and the difference between the second average water temperature and the preset second target temperature is greater than the upper limit of the preset temperature difference interval, indicating that the water temperature is high and the water temperature in the water tank needs to be lowered. If the initial state of the four-way valve is heating mode at this time, the four-way valve needs to be adjusted to cooling mode and then the compressor is started.

[0053] It should be noted that when the target calculation result meets the first preset condition, it means that the temperature abnormalities in the first water tank and the second water tank need to be checked and the seafood machine needs to be started. The target settlement result can be used to determine whether the seafood machine is running in cooling mode or heating mode. For example, if the target calculation result is that the difference between the first average water temperature and the preset first target temperature is less than the lower limit of the preset temperature difference interval and the difference between the second average water temperature and the preset second target temperature is less than the lower limit of the preset temperature difference interval, it means that the seafood machine needs to run in heating mode. If the target calculation result is that the difference between the first average water temperature and the preset first target temperature is greater than the upper limit of the preset temperature difference interval and the difference between the second average water temperature and the preset second target temperature is greater than the upper limit of the preset temperature difference interval, it means that the seafood machine needs to run in cooling mode.

[0054] Reference Figure 3 , Figure 3 This is a flow chart of a seafood machine control method provided in another embodiment of the present application.

[0055] Step S400, when the seafood machine is in working state, obtaining the exhaust temperature of the compressor and the coil temperature of the first heat exchanger;

[0056] Step S410, adjusting the target opening of the electronic expansion valve according to the difference between the exhaust temperature and the coil temperature and the preset temperature.

[0057] It is understandable that when the seafood machine is in working state, as the working time increases, the exhaust temperature of the compressor and the coil temperature of the first heat exchanger will continue to change and can reflect the working state of the seafood machine, and the exhaust temperature of the compressor and the coil temperature of the first heat exchanger can be adjusted by changing the opening of the electronic expansion valve. Therefore, in order to maintain the working state of the seafood machine, the opening of the electronic expansion valve can be adjusted, that is, according to the difference between the exhaust temperature and the coil temperature and the preset temperature, the target opening of the electronic expansion valve is adjusted. For example, the target opening of the electronic expansion valve can be adjusted in a manner as follows: the target opening is equal to the difference between the coil temperature and the preset temperature multiplied by the adjustment coefficient plus the initial opening of the electronic expansion valve. Among them, the coefficient can be determined according to the size of the exhaust temperature. For example, when the exhaust temperature is in the first exhaust temperature interval, the adjustment coefficient is 1.5, when the exhaust temperature is in the second exhaust temperature interval, the adjustment coefficient is 1, and when the exhaust temperature is in the third exhaust temperature interval, the adjustment coefficient is 0.4. Any value in the first exhaust temperature interval is greater than any value in the second exhaust temperature interval, and any value in the second exhaust temperature interval is greater than any value in the third exhaust temperature interval. In some embodiments, the first exhaust temperature interval is 98°C to 104°C (including 98°C), the second exhaust temperature interval is 92°C to 98°C (excluding 98°C), and the third exhaust temperature interval is 82°C to 92°C (excluding 92°C). When the seafood machine is in working state, it means that the compressor, the first heat exchanger and the second heat exchanger are working.

[0058] It should be noted that multiple exhaust temperature ranges can be set according to actual conditions.

[0059] It should be noted that the data collection of the exhaust temperature and the coil temperature is periodic, so as to avoid the reduction of the service life of the electronic expansion valve due to frequent changes in the opening of the electronic expansion valve.

[0060] Reference Figure 4 , Figure 4 yes Figure 3 Specific flow chart of step S410 in FIG.

[0061] Step S411, when the seafood machine is in working state, obtaining the current working mode of the seafood machine;

[0062] Step S412, adjusting the target opening of the electronic expansion valve according to the current working mode, the exhaust temperature and the difference between the coil temperature and the preset temperature.

[0063] It is understandable that in the heating mode and the cooling mode, the exhaust temperature of the compressor and the coil temperature of the first heat exchanger have different effects on the working state of the seafood machine, and in different working modes, the opening adjustment of the electronic expansion valve has different changes in the exhaust temperature of the compressor and the coil temperature of the first heat exchanger. Therefore, the current working mode of the seafood machine can also be obtained, and then the target opening of the electronic expansion valve is adjusted according to the current working mode, the exhaust temperature and the difference between the coil temperature and the preset temperature. For example, the exhaust temperature range is first determined according to the current working mode, and then the adjustment coefficient is determined according to the exhaust temperature range in which the exhaust temperature is located. For example, when the exhaust temperature is in the first exhaust temperature interval, the adjustment coefficient is 1.5, when the exhaust temperature is in the second exhaust temperature interval, the adjustment coefficient is 1, and when the exhaust temperature is in the third exhaust temperature interval, the adjustment coefficient is 0.4. However, in heating mode, the first exhaust temperature interval is 92°C to 98°C (including 92°C), the second exhaust temperature interval is 82°C to 92°C (excluding 92°C), and the third exhaust temperature interval is 72°C to 82°C (excluding 82°C); in cooling mode, the first exhaust temperature interval is 98°C to 104°C (including 98°C), the second exhaust temperature interval is 92°C to 98°C (excluding 98°C), and the third exhaust temperature interval is 82°C to 92°C (excluding 92°C). Adjusting the target opening of the electronic expansion valve in accordance with different working modes can effectively improve the accuracy of the adjustment.

[0064] Reference Figure 5 , Figure 5 This is a flow chart of a seafood machine control method provided in another embodiment of the present application.

[0065] Step S500, when the seafood machine is in working state, obtaining the working time of the compressor, the first working temperature of the first heat exchanger, and the second working temperature of the second heat exchanger;

[0066] Step S510, when the working time reaches the preset defrosting time and the first working temperature or the second working temperature reaches the preset defrosting temperature, the seafood machine is controlled to enter the defrosting state.

[0067] It is understandable that when the seafood machine is in operation, as the working time of the compressor increases, the first heat exchanger and the second heat exchanger may be frosted. For example, in the cooling mode, the first heat exchanger is equivalent to the evaporator, and the first working temperature will continue to drop, which will cause the first heat exchanger to frost. In the heating mode, the second heat exchanger is equivalent to the evaporator, and the second working temperature will continue to drop, which will cause the second heat exchanger to frost. Therefore, when the working time reaches the preset defrosting time and the first working temperature or the second working temperature reaches the preset defrosting temperature, the seafood machine is controlled to enter the defrosting state to avoid a large amount of frost on the heat exchanger.

[0068] Reference Figure 6 , Figure 6 This is a flow chart of a seafood machine control method provided in another embodiment of the present application.

[0069] Step S600, when the seafood machine is in working state, when the first average water temperature or the second average water temperature exceeds the alarm temperature threshold, the seafood machine is controlled to stop running and send an alarm message.

[0070] It is understandable that when the seafood machine is in working condition, the water temperature of the first water tank or the second water tank may be abnormal due to the influence of the external environment or the failure of the first heat exchanger or the second heat exchanger. Therefore, when the seafood machine is in working condition, the first average water temperature and the second average water temperature can be obtained. When the first average water temperature or the second average water temperature exceeds the alarm temperature threshold, the seafood machine is controlled to stop running and send an alarm message to avoid the death of aquatic organisms in the first water tank or the second water tank due to abnormal water temperature. The alarm information can be a sound alarm and a light alarm, and can also be sent to the user's mobile device based on preset user information.

[0071] Reference Figure 7 , Figure 7 This is a flow chart of a seafood machine control method provided in another embodiment of the present application.

[0072] Step S700, when the seafood machine is in working state, obtaining the working time and exhaust temperature of the compressor;

[0073] Step S710, when the working time is greater than the first time threshold and the exhaust temperature is greater than the preset alarm threshold, the seafood machine is controlled to stop running and send an alarm message.

[0074] It is understandable that when the seafood machine is in working condition, the exhaust temperature will rise as the working time of the compressor increases. When the exhaust temperature is greater than the preset alarm threshold, it may cause damage to the compressor or increase the wear of the compressor, thereby reducing the service life of the compressor. Therefore, when the seafood machine is in working condition, the working time and exhaust temperature of the compressor are obtained. When the working time is greater than the first time threshold and the exhaust temperature is greater than the preset alarm threshold, the seafood machine is controlled to stop running and send an alarm message to avoid damage to the compressor. The alarm information can be a sound alarm and a light alarm, and can also be sent to the user's mobile device based on preset user information.

[0075] Reference Figure 8 , Figure 8 This is a flow chart of a seafood machine control method provided in another embodiment of the present application.

[0076] Step S800, obtaining a first water level height of the first water tank and a second water level height of the second water tank;

[0077] Step S810, when the first water level does not meet the preset water level or the second water level does not meet the preset water level, the seafood machine is controlled to stop running and send an alarm message.

[0078] It is understandable that if the water in the water tank is small, the water pump may be unable to pump water. If the seafood machine is running in cooling mode or heating mode at this time, since the water pump cannot pump water, that is, there is no water in the heat exchange pipe, that is, it is impossible to exchange heat with the heat exchanger, it may cause the heat exchange pipe to overheat or overcool, thereby reducing the service life of the heat exchange pipe. Therefore, the first water level of the first water tank and the second water level of the second water tank can be obtained. When the first water level does not meet the preset water level or the second water level does not meet the preset water level, the seafood machine is controlled to stop running and send an alarm message to avoid the reduction of the service life of the heat exchange pipe. Among them, the preset water level can be the minimum pumping height of the water pump, or the minimum water level for aquatic organisms. The alarm information can be a sound alarm and a light alarm, and it can also be an alarm message sent to the user's mobile device based on preset user information.
