[0051] In some cases, fresh aquatic products are readily available in the market and are purchased in huge quantities. However, the problem of their preservation has always been a challenge for consumers. Under ordinary storage methods, fresh aquatic products will become inactive within a few hours, and their taste and nutrition will be greatly reduced. Although existing technologies can extend the shelf life of aquatic products through low-temperature storage, the quality of aquatic products such as shrimp changes significantly after storage. Low-temperature preservation may cause protein denaturation, affecting the taste and quality of aquatic products.

[0052] Based on the above, this application proposes a waterless survival device and its control method, refrigeration equipment and storage medium, aiming to reduce the rate of metabolism and improve the survival rate of aquatic products.

[0053] The various embodiments of the waterless survival device of this application will be further described below with reference to the accompanying drawings.

[0054] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the structure of a waterless survival device provided in one embodiment of this application; Figure 2 This is a schematic diagram of the structure of a waterless survival device provided in another embodiment of this application; Figure 3 This is a schematic diagram of the structure of an oxygen supply module provided in one embodiment of this application.

[0055] In one embodiment, the waterless preservation device 100 is used to install in the refrigeration space of a refrigeration equipment, and the waterless preservation device 100 includes:

[0056] Keep alive drawer 110;

[0057] Oxygen supply module 120 is installed in the keep-alive drawer 110 and is used to adjust the oxygen concentration in the keep-alive drawer 110;

[0058] The temperature control module is used to adjust the temperature of the keep-alive drawer 110.

[0059] In one embodiment, the oxygen supply module 120 is installed inside the survival drawer 110. By filling it with high concentrations of oxygen or mixed gas, it ensures that the aquatic products can maintain their basic respiratory needs even in a waterless state. The temperature control module precisely regulates the temperature inside the drawer to keep it within the ecological ice temperature range of the aquatic products, thereby reducing the metabolic rate of the aquatic products and extending their survival time. At the same time, the waterless survival device 100 is equipped with sensors and a control system that can monitor the oxygen concentration and temperature in real time and automatically adjust the working status of the oxygen supply module 120 and the temperature control module.

[0060] In one embodiment, the oxygen supply module 120 includes an oxygen supply membrane assembly and an oxygen delivery pipe 121. The keep-alive drawer 110 has an oxygen inlet 111. The oxygen supply membrane assembly is used to generate oxygen and deliver it to the interior of the keep-alive drawer 110 through the oxygen delivery pipe 121 and the oxygen inlet 111.

[0061] It should be noted that the oxygen supply pipe 121 delivers the oxygen generated by the oxygen supply membrane assembly to the inside of the liveness drawer 110. The pipe material is made of corrosion-resistant and oxidation-resistant stainless steel or copper pipe to ensure the safety and stability of oxygen supply. Oxygen enters the inside of the drawer evenly through the oxygen inlet 111 to ensure that the aquatic products can come into contact with sufficient oxygen.

[0062] In one embodiment, such as Figure 3 As shown, the inside of the keep-alive drawer 110 is provided with an oxygen supply structure 150, which is connected to the oxygen inlet 111. The oxygen supply structure 150 is provided with multiple oxygen output holes 114. The diameter of the oxygen output holes 114 is smaller than the preset diameter, and the multiple oxygen output holes 114 are arranged in a matrix uniformly.

[0063] It should be noted that the oxygen supply structure 150 is installed inside the live-keeping drawer 110 and is connected to the oxygen inlet 111 via the oxygen supply pipe 121, evenly distributing the high-concentration oxygen generated by the oxygen supply module 120 inside the drawer. Its purpose is to provide sufficient oxygen for aquatic products while avoiding excessively high or low local oxygen concentrations. The oxygen supply structure 150 is equipped with multiple oxygen outlet holes 114. These holes have a diameter smaller than the preset diameter, and the micropore design generates tiny bubbles, thereby increasing the surface area of ​​contact between oxygen and aquatic products, improving oxygen utilization. The micropore design also prevents oxygen from directly impacting the aquatic products, reducing stress reactions.

[0064] In one embodiment, the oxygen outlet holes 114 are evenly distributed on the oxygen supply structure 150 to ensure that the oxygen concentration in the drawer is uniform and consistent, which can avoid local oxygen enrichment and ensure that the aquatic products can obtain sufficient oxygen in all positions in the drawer.

[0065] In one embodiment, the keep-alive drawer 110 is provided with a pressure relief valve 112, and the pressure relief valve 112 and the oxygen inlet 111 are arranged diagonally inside the keep-alive drawer 110.

[0066] It should be noted that the pressure relief valve 112 and the oxygen inlet 111 are arranged diagonally inside the keep-alive drawer 110, which can ensure the uniform distribution of oxygen in the drawer. The diagonal layout allows the oxygen to fully diffuse into the entire drawer space after entering from the oxygen inlet 111, while avoiding excessively high local oxygen concentration. The diagonal layout can also form a more uniform airflow circulation in the drawer, reducing local accumulation of oxygen.

[0067] It should be noted that the pressure relief valve 112 automatically releases excess gas when the pressure inside the drawer rises to a certain level, in order to maintain the stability of the internal pressure. Setting the pressure relief valve 112 at a position diagonally opposite to the oxygen inlet 111 can maximize the use of the space inside the drawer, while ensuring that oxygen can be discharged from a position away from the oxygen inlet 111 when the pressure is released, thus avoiding the waste of oxygen.

[0068] In one embodiment, the temperature control module includes an airflow control component, and the waterless keep-alive device 100 is further provided with a partition, which is disposed adjacent to the keep-alive drawer 110. The airflow control component is used to supply air to the partition so as to transfer the cold energy to the keep-alive drawer 110 through the partition.

[0069] It should be noted that the partition is arranged adjacent to the keep-alive drawer 110 and serves as an intermediate medium for cold energy transfer. The partition is made of a material with good thermal conductivity, which can quickly transfer cold energy from the refrigeration system to the inside of the keep-alive drawer 110. The airflow control component delivers cold air to the partition through the air supply system, thereby lowering the temperature of the partition. The cold energy is evenly transferred to the keep-alive drawer 110 through the partition, avoiding low-temperature damage to aquatic products caused by direct refrigeration. Transferring cold energy through the partition ensures a uniform temperature distribution inside the keep-alive drawer 110, while reducing direct contact between the refrigeration equipment and aquatic products, reducing energy consumption, and extending the equipment life.

[0070] In one embodiment, the airflow control component includes at least one of the following: a damper and a fan.

[0071] It should be noted that the damper is used to regulate the flow of cold air through the partition. The flow of cold air through the partition is regulated by adjusting the opening of the damper. When the drawer temperature drops to the first preset temperature range, the opening of the damper is reduced to decrease the flow of cold air through the partition. When the drawer temperature is higher than the first preset temperature range, the opening of the damper is increased to increase the flow of cold air through the partition. The fan is also used to regulate the flow of cold air through the partition. The flow of cold air through the partition is regulated by adjusting the speed of the fan. When the drawer temperature drops to the first preset temperature range, the speed of the fan is reduced to decrease the flow of cold air through the partition. When the drawer temperature is higher than the first preset temperature range, the speed of the fan is increased to increase the flow of cold air through the partition.

[0072] In one embodiment, the waterless survival device 100 includes a temperature sensor 140 and an oxygen sensor 130. The survival drawer 110 is provided with a heat transfer plate 113. The temperature sensor 140 is installed on the surface of the heat transfer plate 113, and the oxygen sensor 130 is installed inside the survival drawer 110.

[0073] It should be noted that the temperature sensor 140 is installed on the surface of the heat transfer plate 113 to monitor temperature changes inside the keep-alive drawer 110 in real time. The heat transfer plate 113 can quickly transfer cold energy from the refrigeration system to the inside of the drawer. By monitoring the temperature of the heat transfer plate 113, the temperature sensor 140 indirectly reflects the actual temperature inside the drawer, ensuring accurate temperature control and avoiding stress reactions in aquatic products caused by local temperature differences. The oxygen sensor 130 is installed inside the keep-alive drawer 110 to monitor oxygen concentration in real time. By precisely controlling the oxygen concentration, the waterless keep-alive device can provide a suitable low-oxygen environment for aquatic products, reducing their metabolic rate and extending their survival time.

[0074] Based on the hardware structure of the above embodiments, various embodiments of the control method of the waterless survival device of this application are proposed below.

[0075] like Figure 4 As shown, Figure 4 This is a flowchart of a control method for a waterless preservative device provided in one embodiment of this application; as follows: Figure 4 As shown, the control method of the waterless survival device provided in this application embodiment includes, but is not limited to, steps S410, S420, S430 and S440, which will be described in turn below.

[0076] Step S410: In response to the keep-alive activation command, start the temperature control module and oxygen supply module according to the keep-alive activation command;

[0077] Step S420: Cool the keep-alive drawer through the temperature control module to lower the drawer temperature and maintain it within the first preset temperature range;

[0078] Step S430: When the oxygen concentration rises to the preset concentration while the drawer temperature is maintained within the first preset temperature range, the oxygen supply module is turned off.

[0079] Step S440: Continue to turn on the temperature control module to cool the keep-alive drawer, so that the drawer temperature drops from the first preset temperature range and is maintained at the second preset temperature range.

[0080] In one embodiment, after the food is placed into the preservation device, the preservation function is activated, and the preservation drawer door is detected to be closed, a preservation command is issued. The temperature control module and oxygen supply module are activated, supplying oxygen to the preservation drawer through the oxygen pipeline. At the same time, the air damper on the rear side of the preservation device opens, cooling the drawer through a layer-by-layer cooling method. During the preservation process, the temperature sensor continuously monitors the temperature inside the preservation drawer. When the temperature drops to a first preset range, the air damper closes. When the temperature is higher than the first preset temperature range, the air damper continues to open to maintain the temperature within the first preset temperature range. During the preservation process, the oxygen sensor continuously monitors the oxygen content inside the preservation drawer. When the oxygen content reaches the first preset oxygen content, the oxygen supply module and pressure relief valve are shut off, and the air damper reopens. When the temperature inside the preservation drawer drops to a second preset temperature range, the air damper closes. Subsequently, the temperature is maintained within the second preset temperature range by controlling the opening and closing of the air damper until the preservation process ends. This application embodiment creates different temperature gradients in the survival drawer by controlling the temperature control module, such as a first preset temperature range and a second preset temperature range. Furthermore, while maintaining the first preset temperature range, the oxygen concentration is lowered after rising to a preset concentration. This allows aquatic products to enter a low-temperature dormancy state as quickly as possible, reducing stress response, slowing down metabolism, and improving the survival rate of aquatic products.

[0081] Regarding step S430, the growth of microorganisms can be inhibited and oxygen consumption reduced by adjusting the gas ratio in the drawer, thereby extending the shelf life of aquatic products. When the oxygen concentration rises to the preset concentration, the oxygen supply module can be turned off or switched to a low-power standby mode. The oxygen concentration changes are monitored in real time to ensure precise control of oxygen supply.

[0082] In one embodiment, in step S440, ice-temperature preservation technology is used to gradually reduce the drawer temperature from a first preset temperature range to a second preset temperature range. This temperature gradient change can effectively inhibit microbial growth while avoiding cell damage to aquatic products caused by rapid cooling. Through multi-stage temperature control, the shelf life of aquatic products is further extended while maintaining their taste and nutrition.

[0083] In one embodiment, when the system detects an abnormal situation, such as temperature fluctuations exceeding a preset range, the system automatically adjusts the working status of the temperature control module and the oxygen supply module and sends an alarm to the user.

[0084] like Figure 5 As shown, Figure 5 This is a flowchart of a control method for a waterless survival device provided in another embodiment of this application; as shown below. Figure 5As shown in the embodiment of this application, the control method of the waterless keep-alive device includes a temperature control module including an airflow control component. The waterless keep-alive device is also provided with a partition, which is arranged adjacent to the keep-alive drawer. The airflow control component is used to supply air to the partition so as to transfer the cold energy to the keep-alive drawer through the partition. The above step S420 includes, but is not limited to, steps S510 and S520. Each step will be described in turn below.

[0085] Step S510: Monitor the temperature of the keep-alive drawer;

[0086] Step S520: Based on the drawer temperature and the first preset temperature range, control the airflow control component to adjust the flow rate of cold air passing through the partition, so that the drawer temperature drops and is maintained within the first preset temperature range.

[0087] In one embodiment, a high-precision temperature sensor is installed inside the keep-alive drawer to collect temperature data inside the drawer in real time. The temperature sensor can convert temperature changes into electrical signals and transmit them to the controller of the temperature control system. The temperature sensor samples at a high frequency to ensure the real-time performance and accuracy of the temperature data. After receiving the temperature signal, the controller compares it with a preset first temperature range to determine whether the temperature needs to be adjusted.

[0088] In one embodiment, when the detected drawer temperature exceeds a first preset temperature range, the system will adjust the airflow through the airflow control component according to the magnitude of the temperature deviation. The adjustment command can be obtained by using a control algorithm to calculate a suitable airflow adjustment command based on the temperature error. The system will continuously monitor temperature changes and dynamically adjust the airflow based on real-time data.

[0089] In addition, it is understood that the type of temperature sensor can be a capacitive temperature sensor, a resistive temperature sensor, a semiconductor temperature sensor, or other types of temperature sensors. This application does not limit the specific type of temperature sensor.

[0090] In one embodiment, the airflow control component includes a damper; the airflow control component is controlled to adjust the flow rate of cold air flowing through the partition according to the drawer temperature and a first preset temperature range, including at least one of the following: when the drawer temperature drops to the first preset temperature range, the opening of the damper is reduced to reduce the flow rate of cold air flowing through the partition; when the drawer temperature is higher than the first preset temperature range, the opening of the damper is increased to increase the flow rate of cold air flowing through the partition.

[0091] In one embodiment, a temperature sensor collects temperature data inside the drawer in real time and transmits this data to a controller. The controller determines whether the current temperature is within an ideal range based on a preset first temperature range. When the drawer temperature is higher than the first preset temperature range, the system triggers an instruction to increase the cold air flow. The system increases the opening of the damper to increase the cold air flow and quickly lower the drawer temperature. At this time, a fan speed controller or a solenoid valve can also work in conjunction. When the temperature drops to within the first preset temperature range, the cold air flow is reduced. The system reduces the cold air flow through the partition by decreasing the opening of the damper. The damper opening can be dynamically adjusted according to a control algorithm to ensure that the temperature remains stable within the preset range. By dynamically adjusting the cold air flow, the system can not only ensure that the drawer temperature is always in an ideal state, but also effectively reduce energy consumption and improve the operating efficiency of the equipment.

[0092] In one embodiment, the airflow control component includes a fan; the airflow control component is controlled to adjust the flow rate of cold air flowing through the partition according to the drawer temperature and a first preset temperature range, including at least one of the following: when the drawer temperature drops to the first preset temperature range, the fan speed is reduced to reduce the flow rate of cold air flowing through the partition; when the drawer temperature is higher than the first preset temperature range, the fan speed is increased to increase the flow rate of cold air flowing through the partition.

[0093] In one embodiment, the fan flow rate is directly proportional to the fan speed. By adjusting the fan speed, the flow rate of cold air passing through the drawer can be changed. When the drawer temperature drops to a first preset temperature range, the system reduces the fan speed, thereby reducing the cold air flow rate. This adjustment method can reduce the supply of cooling energy, avoid excessively low temperatures, and save energy. When the drawer temperature is higher than the first preset temperature range, the system increases the fan speed, increasing the cold air flow rate to quickly lower the temperature inside the drawer. By adjusting the fan speed to control the cold air flow rate, precise regulation of the drawer temperature can be achieved.

[0094] In one embodiment, the oxygen-keeping drawer is equipped with a pressure relief valve that closes when the oxygen concentration rises to a preset concentration.

[0095] It should be noted that the pressure relief valve is used to maintain the pressure balance inside the live drawer. When the oxygen concentration inside the drawer rises to the preset concentration, it means that the air pressure inside the drawer may have increased due to biological respiration or other factors. Closing the pressure relief valve can prevent excessive oxygen loss and avoid adverse effects on the aquatic products inside the drawer due to excessive pressure.

[0096] In one embodiment, an oxygen concentration sensor is installed in the keep-alive drawer to monitor the oxygen concentration in real time. When the oxygen concentration reaches a preset high value, the system will automatically close the pressure relief valve, thereby ensuring that the oxygen concentration in the drawer is maintained within a suitable range and avoiding insufficient oxygen due to frequent pressure relief.

[0097] In one embodiment, the keep-alive opening command is generated through one of the following steps: when a keep-alive drawer door closing command and a keep-alive function operation command input by the user are received, a keep-alive opening command is generated in response; when it is detected that the keep-alive drawer contains food and a keep-alive drawer door closing command is received, a keep-alive opening command is generated in response.

[0098] In one embodiment, when a user places food into the keep-alive drawer and closes the drawer door, the system receives a door-closing command. Simultaneously, the user can input a keep-alive function operation command through the user interface. When both the door-closing command and the input keep-alive function operation command are satisfied, the system generates a keep-alive activation command to start the keep-alive function. For example, after placing food in the drawer, the user confirms the start of the keep-alive function using the "Keep-alive Mode" button on the refrigerator panel. At this time, the system will detect whether the door is closed and generate a keep-alive activation command based on the user's operation command.

[0099] In one embodiment, the system can detect whether food is stored in the keep-alive drawer using sensors. When food is detected in the drawer and the door is closed, the system automatically generates a keep-alive opening command, which can reduce user operation steps and improve user experience. For example, the keep-alive drawer is equipped with a weight sensor or camera to detect whether there is food in the drawer.
