Description
Technical Field
[0001] This application belongs to the field of household appliance technology, and in particular relates to a storage device, control method, apparatus, and storage medium. Background Technology
[0002] With the development of technology, storage devices such as refrigerators and freezers are becoming increasingly common in daily life. When closing a refrigerator or freezer, the pressure inside can become too high due to the compression of the gas within the storage space. This can cause the door to gap or be forced open. If the door is not closed again, abnormal frost buildup can occur. Therefore, users usually need to close the door with both hands and double-check that everything is closed, leading to a poor user experience. Furthermore, when opening the door, the enclosed space causes the air pressure inside to decrease as it cools down, making it very difficult to open. Summary of the Invention

[0017] In the current opening state, the pressure reducing pump is controlled to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is less than or equal to the pressure outside the box.
[0018] According to one embodiment of this application, adjusting the opening state of the damper based on the first pressure information includes:
[0019] When the pressure inside the first pressure information characterization box is greater than the first preset threshold, the opening state of the damper is adjusted to the first opening.
[0020] When the pressure inside the first pressure information characterization box is less than or equal to the first preset threshold, the opening state of the damper is adjusted to the second opening; the first opening is greater than the second opening.
[0021] According to one embodiment of this application, in the current opening state, controlling the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is less than or equal to the pressure outside the box, includes:
[0022] At the first opening degree, the pressure reducing pump is controlled to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is equal to the pressure outside the box.
[0023] According to one embodiment of this application, in the current opening state, controlling the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is less than or equal to the pressure outside the box, further includes:
[0024] At the second opening degree, the pressure reducing pump is controlled to discharge the gas inside the box to the outside of the box through the damper, and the suction valve is controlled to draw in external gas into the inside of the box so that the pressure inside the box is less than the pressure outside the box.

When the internal pressure of the storage equipment is at a normal level, the small-opening dampers can be used to slowly adjust the internal pressure, completing the ventilation operation. This not only improves the airtightness and ease of use of the storage equipment, but also ensures the freshness of the air inside the storage equipment, thus enhancing the user experience.
[0036] Furthermore, since the opening of the damper is adjustable, when the internal pressure of the storage equipment is too high, the large-opening damper can be used to quickly balance the internal and external pressure of the storage equipment. During normal ventilation, the small-opening damper can be used to adjust slowly, thereby avoiding excessive internal pressure fluctuations and improving the stability of the storage environment.
[0037] Furthermore, by cooperating with the suction valve and the pressure reducing pump, the suction valve draws external gas into the storage device and the pressure reducing pump sends the gas inside the device to the outside, thereby realizing the circulation of gas inside and outside the device and ensuring the freshness of the gas inside the storage device.
[0038] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0046] In related technologies, when refrigerators, freezers and other storage devices are closed, the pressure inside the cabinet becomes too high due to gas compression at the moment the door is closed, which can easily cause the door to gap or be forced open. If the door is not closed again, abnormal frost will form on the refrigerator. Therefore, users usually need to use both hands to close the door, resulting in a poor user experience.
[0047] The storage device, control method, apparatus, and storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0048] This application provides an embodiment of a storage device, please refer to... Figure 1 The storage device includes: a housing 110, a door 120, an air damper 130, and a pressure reducing pump 140, wherein...
[0049] The box body 110 has a storage room 111 inside.
[0050] The door 120 is movably located on the front side of the box 110 and is used to open or close the storage room 111.
[0051] The damper 130 is located on the wall of the housing 111 and includes at least two opening states; the ventilation efficiency is different for different opening states.
[0052] A pressure reducing pump 140 is located inside the housing 111 and is connected to a damper 130 via a duct 150. It is used to discharge the gas inside the housing 110 to the outside of the housing through the damper so that the pressure inside the housing is less than or equal to the pressure outside the housing.
[0053] In this embodiment, the storage device can be understood as a broad category of refrigeration storage device, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage devices have diverse structural forms and wide applications. The storage compartment 111 can be one or more storage areas inside the storage device, such as at least one of the refrigerator compartment and freezer compartment of a refrigerator. The door 120 can be movably connected to the cabinet 110; for example, one side of the door 120 can rotate around an axis to open the storage compartment 111 by rotating outwards, or to close the storage compartment 111 by rotating inwards. The damper 130 can be disposed on the rear wall of the cabinet 111, opposite to the door 120. It should be noted that the number of dampers 130 can be one, two, or more. When there is only one damper 130, the opening state of that damper can represent the overall opening state; when there are two or more dampers 130, the opening states of these dampers need to be considered comprehensively. Here, with a fixed power of the pressure reducing pump 140, the larger the total opening of the damper 130, the greater the corresponding ventilation efficiency. Ventilation efficiency characterizes the efficiency of air exchange between the inside and outside of the storage equipment. The pressure reducing pump 140 is connected to the damper 130 via the duct 150. When a larger pressure is required inside the storage equipment, the pressure reducing pump 140 starts working, which can send at least a portion of the gas inside the equipment to the outside through the duct 150 and the damper 130, thereby reducing the pressure inside the equipment.
[0054] In one example, the storage device is a refrigerator. When the refrigerator door is closed, the gas inside is compressed, causing an increase in internal pressure. A pressure-reducing pump then activates, expelling some of the gas from the refrigerator through air ducts and dampers. This ensures that when the door is closed, the pressure on the inner side of the door closest to the storage compartment does not exceed the pressure on the outer side, allowing for a smooth closing action.
[0055] The storage device of this application uses a pressure reducing pump in conjunction with an adjustable damper to regulate the internal pressure of the storage device. When the internal pressure of the storage device is too high, the large-opening damper can be used to quickly reduce the internal pressure. When the internal pressure of the storage device is at a normal level, the small-opening damper can be used to slowly adjust the internal pressure to complete the ventilation operation. This not only improves the airtightness and ease of use of the storage device, but also ensures the freshness of the air inside the storage device, thus improving the user experience.
[0056] In some embodiments, the storage device may further include an air intake valve; the air intake valve is disposed on the wall of the housing and extends through the interior of the housing, for drawing in external gas into the interior of the housing.
[0057] In this embodiment, the function of the suction valve is the opposite of that of the pressure reducing pump. The function of the suction valve is to draw in gas from outside the storage device into the storage device to increase the internal pressure, or to exchange gas with the outside of the storage device.
[0058] Considering that storage compartments often contain various foods, some of which may produce odors, and that these odors can easily spread if not removed promptly, a pressure-reducing pump can be used to expel the gas inside the storage unit, while an air intake valve can draw in external gas. This allows for gas exchange between the inside and outside of the storage unit, ensuring fresh air inside and improving the user experience.
[0059] In some embodiments, the storage device may also include a pressure sensor, a stepper motor, and a controller.
[0060] The pressure sensor is located inside the enclosure and is used to detect the pressure information inside the enclosure.
[0061] The controller, connected to the pressure sensor and stepper motor, controls the stepper motor and the corresponding gear assembly to adjust the opening of the damper when the received pressure information meets the preset threshold conditions.
[0062] In this embodiment, multiple pressure sensors can be used, each located at a different position inside the storage device, to provide comprehensive and accurate feedback on the internal pressure. When discrepancies exist in the pressure readings from multiple sensors, significantly different pressure values can be filtered out, and the average of the closest pressure values can be used as the basis for judgment. After the stepper motor is powered on, it adjusts the opening of the damper via a gear reduction transmission mechanism. By using a large-opening damper when the internal pressure of the storage device is too high, the internal and external pressures can be quickly balanced. During normal ventilation, a small-opening damper is used for slow adjustment, thereby preventing excessive internal pressure fluctuations and improving the stability of the storage environment.
[0063] In some embodiments, the control method for a storage device provided in this application can be executed by the storage device itself or by a functional module or entity within the storage device that can implement the control method. This functional module or entity can be part of the storage device or an individual electrically connected to the storage device. The control method provided in this application will be described below using the storage device as an example.
[0064] This application provides a control method for a storage device, applied to the aforementioned storage device, comprising:
[0065] Step 210: Obtain the first pressure information inside the storage device.
[0066] In this embodiment, the storage device can be understood as a broad category of refrigeration storage device, including but not limited to refrigerators, freezers, display cases, beverage cabinets, wine cabinets, refrigerated display cases, and refrigerated vending machines. Storage devices have diverse structural forms and wide applications. Multiple pressure sensors located at different positions inside the storage device can detect the internal pressure and obtain initial pressure information. When there are differences in the pressure detected by multiple pressure sensors, pressure values with large differences can be filtered out, and the average of the closest pressure values can be used as the initial pressure information. Since the multiple pressure sensors are located in different positions, the initial pressure information can comprehensively and accurately reflect the internal pressure environment of the storage device.
[0067] Step 220: Adjust the opening state of the damper based on the first pressure information; different opening states correspond to different air exchange efficiencies.
[0068] Here, a pre-set pressure threshold can be used as the basis for adjusting the damper opening. For example, when the indoor pressure, as indicated by the first pressure information, is greater than the pressure threshold, the damper opening begins to adjust; otherwise, no adjustment is made. As the pressure inside the chamber gradually decreases to below the pressure threshold, the damper opening begins to adjust again. The two adjustments are in opposite directions: the former increases the damper opening to increase the ventilation efficiency, while the latter decreases the damper opening to decrease the ventilation efficiency.
[0069] Step 230: Under the current opening state, control the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage equipment is less than or equal to the pressure outside the box.
[0070] The opening degree of the damper should have at least two states: large and small. When the pressure inside the storage unit is too high, even to the point of affecting door closure, it's necessary to quickly reduce the internal pressure. Therefore, a large-opening damper is required. Here, simply reduce the internal pressure to equal the external pressure. When the internal and external pressures are roughly balanced, to ensure a tight door closure, the internal pressure can be gradually reduced. In this case, a small-opening damper is sufficient to reduce the internal pressure to less than the external pressure, preventing excessive internal pressure fluctuations.
[0071] This embodiment utilizes a pressure reducing pump and dampers located on the walls of the storage unit to balance the internal and external pressures of the storage device. When the internal pressure of the storage device is too high, the large-opening dampers can be used to quickly reduce the internal pressure. When the internal pressure of the storage device is at a normal level, the small-opening dampers can be used to slowly adjust the internal pressure, completing the ventilation operation. This not only improves the airtightness and ease of use of the storage device but also ensures the freshness of the air inside the storage device, enhancing the user experience.
[0072] In some embodiments, step 220, adjusting the opening state of the damper based on the first pressure information, may include:
[0073] When the pressure inside the first pressure information characterization box is greater than the first preset threshold, the opening state of the damper is adjusted to the first opening.
[0074] When the pressure inside the first pressure information characterization box is less than or equal to the first preset threshold, the opening state of the damper is adjusted to the second opening; the first opening is greater than the second opening.
[0075] Understandably, when the internal pressure is too high, the damper opens wide to quickly reduce the internal pressure of the storage device. When the internal pressure is normal, the damper opens slightly to avoid excessive pressure fluctuations. Here, the first preset threshold can be determined based on actual testing conditions to ensure that the storage device door can close properly and maintain good airtightness when the internal pressure is less than or equal to the first preset threshold; its specific value is not limited.
[0076] In one example, the damper can have two opening states: a first opening state and a second opening state, where the first opening state corresponds to a larger first opening than the second opening state. Under normal circumstances, the damper remains in the second opening state. When the internal pressure of the storage device reaches a preset pressure value, the damper switches from the second opening state to the first opening state to quickly reduce the internal pressure and improve the airtightness of the storage device. It should be noted that the damper can also have multiple opening states, each corresponding to a different opening degree. Correspondingly, multiple pressure values can be used for judgment and classification to achieve more precise control. The principle is the same as in the previous example and will not be elaborated further.
[0077] In another example, the internal and external pressures of the storage unit reach equilibrium, at which point the fan remains at its second opening position. Considering that various foods are often stored inside the storage compartment, and some foods may produce odors, cross-contamination of smells can easily occur if these odors are not removed promptly. Therefore, a pressure-reducing pump can be used to send the internal gas of the storage unit outside, while an air intake valve draws external gas into the storage unit. This completes the gas exchange between the inside and outside of the storage unit, ensuring the freshness of the internal air and improving the user experience. Furthermore, by using a small-opening damper for slow adjustment, excessive internal pressure fluctuations are avoided, enhancing the stability of the storage environment.
[0078] In some embodiments, step 230, in the current opening state, controlling the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is less than or equal to the pressure outside the box, may include:
[0079] In the first opening position, the pressure reducing pump is controlled to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage equipment is equal to the pressure outside the box.
[0080] In this embodiment, in the initial stage, the pressure inside the box is greater than the pressure outside the box, making it difficult to close the door of the storage device. The gas inside the box is discharged to the outside of the box through the first opening of the air damper by the pressure reducing pump, so that the pressure inside and outside the box can be quickly balanced.
[0081] In one example, the door of the storage device switches from an open to a closed state, causing the gas inside the storage space to be compressed, increasing the internal pressure. A pressure sensor inside the storage device transmits the detected pressure information to the corresponding controller. The controller controls the damper opening and the pressure reducing pump to operate, thereby expelling at least some of the gas inside the device through the damper to the outside, ensuring that the internal pressure of the storage device equals the external pressure, facilitating a tight door closure.
[0082] In some embodiments, step 230, in the current opening state, controlling the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage device is less than or equal to the pressure outside the box, may further include:
[0083] At the second opening position, the pressure reducing pump is controlled to discharge the gas inside the chamber to the outside of the chamber through the damper, and the suction valve is controlled to draw in external gas into the chamber so that the pressure inside the chamber is lower than the pressure outside the chamber.
[0084] In this embodiment, initially, the pressure inside and outside the storage device box is basically balanced, that is, the pressure inside the box is equal to the pressure outside the box. Here, by controlling the pressure reducing pump, the gas inside the box is discharged to the outside of the box through the second-degree opening damper, so that the pressure inside the box is less than the pressure outside the box. The door of the storage device is subjected to a pressure inside the box, which improves the airtightness of the storage device.
[0085] In one example, while controlling the pressure reducing pump to discharge the gas inside the box to the outside of the box through the damper, the suction valve can also be controlled to draw in external gas into the box, thereby completing the gas exchange between the inside and outside of the storage device, ensuring the freshness of the gas inside the storage device, and improving the user experience.
[0086] In some embodiments, step 220, adjusting the opening state of the damper based on the first pressure information, may further include:
[0087] Obtain the second pressure information inside the storage room after ventilation is completed;
[0088] When the pressure inside the second pressure information characterization box is less than the second preset threshold, the opening state of the damper is adjusted to zero; the second preset threshold is less than the first preset threshold.
[0089] In this embodiment, considering that the pressure difference between the internal and external pressures of the storage device is too great, the door of the storage device will be subjected to significant pressure and be difficult to open. Therefore, when the internal pressure is less than a second preset threshold, the opening degree of the damper is adjusted to zero to prevent further reduction in internal pressure and ensure convenient door opening. Here, the second preset threshold can be determined according to actual needs and is not limited thereto.
[0090] It should be noted that the opening degree of the damper can be controlled by adding a clock. After a preset time period, the damper can switch from zero opening to the second opening degree to allow air exchange with the outside of the storage equipment, preventing odors from lingering inside the box and causing the stored food to absorb other smells.
[0091] This embodiment of the application uses a pressure reducing pump in conjunction with an adjustable damper to regulate the internal pressure of the storage device. When the internal pressure of the storage device is too high, the large-opening damper can be used to quickly reduce the internal pressure. When the internal pressure of the storage device is at a normal level, the small-opening damper can be used to slowly adjust the internal pressure to complete the ventilation operation. This not only improves the airtightness and ease of use of the storage device, but also ensures the freshness of the gas inside the storage device, thus improving the user experience.
[0092] This application also provides a control device for a storage device; please refer to [link / reference]. Figure 3The control device 300 of the storage equipment includes: an acquisition module 310, an adjustment module 320, and a control module 330. Among them,
[0093] The acquisition module 310 is configured to acquire the first pressure information inside the storage device.
[0094] The adjustment module 320 is configured to adjust the opening state of the damper based on the first pressure information; different opening states correspond to different air exchange efficiencies.
[0095] The control module 330 is configured to control the pressure reducing pump to discharge the gas inside the chamber to the outside of the chamber through the damper in the current opening state, so that the pressure inside the chamber is less than or equal to the pressure outside the chamber.
[0096] In this embodiment, the acquisition module may include multiple pressure sensors, which are located at different positions inside the storage device. These multiple pressure sensors are used to detect the pressure inside the storage device to acquire first pressure information. When there are differences in the pressure detected by the multiple pressure sensors, pressure values with large differences can be filtered out, and the average of the pressure values that are close in magnitude can be used as the first pressure information.
[0097] The damper can have two opening states: a first opening state and a second opening state, where the first opening state corresponds to a larger first opening than the second opening state. Under normal circumstances, the damper remains in the second opening state. When the internal pressure of the storage device reaches a preset pressure value, the control module switches the damper's opening state from the second opening state to the first opening state to quickly reduce the internal pressure of the storage device and improve its airtightness.
[0098] When the internal and external pressures of the storage unit reach equilibrium, the fan remains at its second opening position. Considering that various foods are often stored inside the storage compartment, and some foods may produce odors, which can easily lead to cross-contamination if not removed promptly, the control module can control a pressure-reducing pump to expel the gas inside the storage unit and draw in external gas through an intake valve. This completes the gas exchange between the inside and outside of the storage unit, ensuring fresh air inside and improving user experience. Furthermore, the use of a small-opening damper for slow adjustment prevents excessive internal pressure fluctuations, enhancing the stability of the storage environment.
[0099] In some embodiments, the adjustment module 320 can be specifically configured as follows:
[0100] When the pressure inside the first pressure information characterization box is greater than the first preset threshold, the opening state of the damper is adjusted to the first opening.
[0101] When the pressure inside the first pressure information characterization box is less than or equal to the first preset threshold, the opening state of the damper is adjusted to the second opening; the first opening is greater than the second opening.
[0102] Understandably, when the internal pressure is too high, the damper opens wide to quickly reduce the internal pressure of the storage device. When the internal pressure is normal, the damper opens slightly to avoid excessive pressure fluctuations. Here, the first preset threshold can be determined based on actual testing conditions to ensure that the storage device door can close properly and maintain good airtightness when the internal pressure is less than or equal to the first preset threshold; its specific value is not limited.
[0103] In some embodiments, the control module 330 may be specifically configured as follows:
[0104] In the first opening position, the pressure reducing pump is controlled to discharge the gas inside the box to the outside of the box through the damper, so that the pressure inside the storage equipment is equal to the pressure outside the box.
[0105] In this embodiment, initially, the pressure inside the container is greater than the pressure outside, making it difficult to close the door. A pressure-reducing pump discharges the gas inside the container through a damper with a first opening, quickly bringing the pressure inside and outside the container to equilibrium. For example, when the door of the storage device switches from an open to a closed state, the gas inside the storage space is compressed, increasing the pressure inside the container. A pressure sensor inside the storage device transmits the detected pressure information to a corresponding controller. The controller controls the damper opening and the pressure-reducing pump to discharge at least a portion of the gas inside the container through the damper to the outside, ensuring that the pressure inside the container equals the pressure outside, facilitating a tight door closure.
[0106] In some embodiments, the control module 330 may further be configured as follows:
[0107] At the second opening position, the pressure reducing pump is controlled to discharge the gas inside the chamber to the outside of the chamber through the damper, and the suction valve is controlled to draw in external gas into the chamber so that the pressure inside the chamber is lower than the pressure outside the chamber.
[0108] In this embodiment, initially, the pressure inside and outside the storage device is essentially balanced, meaning the pressure inside the device equals the pressure outside. Here, by controlling the pressure-reducing pump to discharge the gas inside the device through a second-degree opening damper, the internal pressure becomes lower than the external pressure, and the door of the storage device experiences pressure inward, improving its airtightness. Furthermore, while controlling the pressure-reducing pump to discharge the gas inside the device through the damper, the suction valve can also be controlled to draw in external gas into the device, thus completing gas exchange between the inside and outside of the storage device, ensuring the freshness of the gas inside and improving the user experience.
[0109] In some embodiments, the adjustment module 320 may further be configured as follows:
[0110] Obtain the second pressure information inside the storage room after ventilation is completed;
[0111] When the pressure inside the second pressure information characterization box is less than the second preset threshold, the opening state of the damper is adjusted to zero; the second preset threshold is less than the first preset threshold.
[0112] In this embodiment, considering that excessive pressure difference between the internal and external surfaces of the storage device would cause significant stress on the door, making it difficult to open, the damper's opening is adjusted to zero when the internal pressure is below a second preset threshold. This prevents further pressure reduction and ensures easy door opening. The second preset threshold can be determined based on actual needs and is not restricted. After a preset time period, the damper can switch from zero to the second opening to allow ventilation between the storage device and the outside.
[0113] This embodiment of the application uses a pressure reducing pump in conjunction with an adjustable damper to regulate the internal pressure of the storage device. When the internal pressure of the storage device is too high, the large-opening damper can be used to quickly reduce the internal pressure. When the internal pressure of the storage device is at a normal level, the small-opening damper can be used to slowly adjust the internal pressure to complete the ventilation operation. This not only improves the airtightness and ease of use of the storage device, but also ensures the freshness of the gas inside the storage device, thus improving the user experience.
