Description

Technical Field

[0001] This application relates to the field of defrosting technology, and more particularly to defrosting methods for refrigeration equipment. Background Technology

[0002] With technological advancements and improved living standards, the requirements for food storage are becoming increasingly stringent. Deep-freeze refrigerators, with their low cooling temperatures, provide excellent food preservation. However, the cooling temperature of deep-freeze refrigerators is typically -60°C or even lower. When the refrigerator door is opened, warm, humid air from the outside environment may enter the refrigerator, causing frost to form on the inner walls and affecting cooling efficiency.

[0003] In related technologies, a transport refrigeration system is provided, including a container with a doorway equipped with at least one door; a refrigeration system including a first reversible fan for driving air along an airflow path and a heat exchanger for cooling air along the airflow path; and a second fan configured to drive an air curtain flow downward through the doorway in at least one operating mode. This method, by using the second fan to form an air curtain flow of air from the external environment at the doorway, reduces the amount of air from the external environment entering the refrigerated space, thereby reducing frost formation in the refrigerated space.

[0004] However, in related technologies, the air curtain has limited effect on blocking air from the external environment, and some air still enters, causing frost to form on the inner wall of the cabinet, which affects the cooling effect. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the related art. To this end, this application proposes a defrosting method for refrigeration equipment, which can form a field at the opening of the storage space of the refrigeration equipment to block and condense the humid and hot air in the external environment, thereby blocking and condensing the humid and hot air in the environment, blocking and reducing the water vapor entering the storage space, effectively preventing frost from forming on the inner wall of the storage space, and improving the refrigeration effect of the refrigeration equipment.

[0006] The defrosting method of a refrigeration device according to the first aspect embodiment of this application, the refrigeration device comprising:

[0007] The inner liner has a storage space, and an opening is provided on one side of the storage space;

[0008] A door, which is located at the opening, is used to close or open the opening;

[0009] A field generating mechanism, at least a portion of which is disposed at the opening, the field generating mechanism being connected to a first cold source, the field generating mechanism being used to form a field on the side of the door facing the opening, at least along the cross-sectional direction of the opening, to prevent water vapor from entering the storage space;

[0010] The defrosting method of the refrigeration equipment includes:

[0011] Upon receiving a start signal, the field generating mechanism is activated to form a field at least along the cross-sectional direction of the opening to block entry into the storage space.

[0012] In this embodiment, a field generating mechanism is provided, with at least a portion of it positioned at the opening. Furthermore, the field generating mechanism is connected to a first cold source. Upon receiving a start signal, the field generating mechanism activates, creating a field that blocks and condenses water vapor in the cross-sectional direction of the opening. Specifically, the field can cause humid air or water vapor within the humid air to move directionally along the field's direction and condense and settle at the first cold source. This prevents humid air from penetrating into the storage space and reduces the movement of water vapor into the storage space. In other words, it blocks humid air from the environment, reducing the amount of water vapor entering the storage space, effectively preventing frost formation on the inner walls of the storage space and improving the cooling effect of the refrigeration equipment.

[0013] According to one embodiment of this application, the door body is provided with a trigger switch, which is used to emit a trigger signal; the activation signal includes the trigger signal; the step of activating the field generating mechanism upon receiving the activation signal to form a field for blocking entry into the storage space at least along the cross-sectional direction of the opening specifically includes:

[0014] Upon receiving the trigger signal, the field generating mechanism is activated.

[0015] In this embodiment, a trigger switch is installed on the door, and the trigger signal emitted by the trigger switch can be used as a start signal. In this way, the refrigeration equipment can start the field generating mechanism in time when the door is opened, and form a field in the cross-sectional direction of the opening. This blocks, transports, and condenses water vapor that permeates into the storage space from the external environment, effectively reducing the occurrence of water vapor entering the storage space and effectively preventing frost from forming on the inner wall of the storage space, thereby improving the refrigeration effect of the refrigeration equipment.

[0016] According to one embodiment of this application, the door body is provided with a locking member, the locking member being used to lock the door body and the outer casing of the refrigeration equipment; after the step of activating the field generating mechanism upon receiving the trigger signal, the method further includes:

[0017] Monitor whether the first operating state of the field generating mechanism meets the first preset condition;

[0018] When the first operating state meets the first preset condition, the locking component is unlocked.

[0019] In this embodiment, a locking element is provided on the door to lock the door to the outer shell of the refrigeration equipment. The locking element is unlocked after the first operating state of the field generating mechanism reaches the first preset condition. This ensures that the user can open the door of the refrigeration equipment only after the field generated by the field generating mechanism along the cross-sectional direction of the opening is stable. This effectively ensures that the field generated by the field generating mechanism blocks and condenses the humid and hot air in the external environment, effectively reduces the occurrence of water vapor entering the storage space, effectively avoids frost formation on the inner wall of the storage space, and improves the refrigeration effect of the refrigeration equipment.

[0020] According to one embodiment of this application, after the step of unlocking the locking member when the first operating state reaches the first preset condition, the method further includes:

[0021] Upon receiving the locking signal from the locking element, monitor whether the second operating state of the field generating mechanism has reached the second preset condition;

[0022] When the second operating state reaches the second preset condition, the field generation mechanism is stopped.

[0023] In this embodiment, after receiving the locking signal from the locking element (i.e., the door of the refrigeration equipment is closed), the field generating mechanism continues to operate. After the second operating state of the field generating mechanism reaches the second preset condition, the operation of the field generating mechanism is stopped. In this way, the operation of the field generating mechanism is guaranteed to have a certain redundancy time. During the redundancy time period, some water vapor that has not been completely condensed can be completely condensed, which can effectively reduce the occurrence of water vapor entering the storage space and effectively prevent frost from forming on the inner wall of the storage space, thereby improving the refrigeration effect of the refrigeration equipment.

[0024] According to one embodiment of this application, the step of monitoring whether the second operating state of the field generating mechanism reaches a second preset condition upon receiving a locking signal from the locking member specifically includes:

[0025] Monitor whether the air humidity at the opening is less than or equal to a preset humidity threshold;

[0026] If the air humidity is less than or equal to the preset humidity threshold, it is determined that the second operating state has reached the second preset condition;

[0027] And / or,

[0028] Monitor whether the second operating time of the field generating mechanism is greater than or equal to the second preset time length;

[0029] If the second running time is greater than or equal to the second preset time length, it is determined that the second running state has reached the second preset condition.

[0030] According to one embodiment of this application, the field generating mechanism includes an airflow field generating mechanism, wherein the airflow outlet of the airflow field generating mechanism is located on the side of the door facing the storage space, and the airflow outlet is used to form an airflow field at least along the cross-sectional direction of the opening;

[0031] The step of monitoring whether the first operating state of the field generating mechanism has reached the first preset condition specifically includes:

[0032] Monitor whether the temperature of the airflow inlet is less than or equal to a preset temperature threshold;

[0033] If the temperature is less than or equal to the preset temperature threshold, it is determined that the first operating state has reached the first preset condition.

[0034] And / or,

[0035] Monitor whether the first operating time of the airflow generating mechanism is greater than or equal to the first preset time length;

[0036] If the first running time is greater than or equal to the first preset time length, it is determined that the first running state has reached the first preset condition.

[0037] According to one embodiment of this application, the field generating mechanism further includes an electric field generating mechanism, wherein two plates of the electric field generating mechanism are disposed opposite to each other on both sides of the opening, and the electric field generating mechanism is used to generate an electric field at the opening;

[0038] The step of monitoring whether the first operating state of the field generating mechanism has reached the first preset condition specifically includes:

[0039] Monitor whether the electric field strength of the electric field is greater than or equal to the preset electric field strength;

[0040] When the electric field strength is greater than or equal to the preset electric field strength, it is determined that the first operating state has reached the first preset condition.

[0041] According to one embodiment of this application, the field generating mechanism further includes a microwave field generating mechanism, wherein the microwave generator of the microwave field generating mechanism is arranged along the cross-sectional direction of the opening, and the microwave field generating mechanism is used to generate a microwave field along the cross-sectional direction of the opening;

[0042] The step of monitoring whether the first operating state of the field generating mechanism has reached the first preset condition specifically includes:

[0043] Monitor whether the oscillation frequency of the microwave field generating mechanism is greater than or equal to the preset oscillation frequency;

[0044] If the oscillation frequency is greater than or equal to the preset oscillation frequency, it is determined that the first operating state has reached the first preset condition.

[0045] According to one embodiment of this application, the refrigeration device further includes a refrigeration mechanism, which is connected to the storage space and is used to deliver circulating refrigeration air to the storage space;

[0046] The step of activating the field generating mechanism upon receiving a start signal specifically includes:

[0047] Upon receiving the start signal, the refrigeration mechanism is stopped;

[0048] If the refrigeration mechanism is determined to be stopped, the field generation mechanism is started.

[0049] In this embodiment, by setting the refrigeration mechanism and the field generation mechanism of the refrigeration equipment to two independent operating conditions, the negative pressure formed by the circulating refrigeration air in the storage space can be effectively avoided after the door of the refrigeration equipment is opened. This prevents the intake of humid and hot air from the external environment into the storage space, effectively reduces the entry of water vapor into the storage space, and effectively prevents frost from forming on the inner wall of the storage space, thus improving the refrigeration effect of the refrigeration equipment. In addition, it also prevents the airflow from blowing into the storage space at the opening, which would affect the user when retrieving items, thus improving the user experience.

[0050] According to one embodiment of this application, the field generating mechanism includes an airflow field generating mechanism, the airflow outlet of the airflow field generating mechanism is located on the side of the door facing the storage space, the airflow outlet is used to form an airflow field at least along the cross-sectional direction of the opening, and a first control valve is provided on the airflow path of the airflow field; a second control valve is provided in the airflow channel of the refrigeration mechanism;

[0051] The step of stopping the refrigeration mechanism upon receiving the start signal specifically includes:

[0052] Upon receiving the start signal, the second control valve is closed;

[0053] The step of activating the field generating mechanism when the refrigeration mechanism is determined to be stopped specifically includes:

[0054] If the second control valve is determined to be closed, the first control valve is opened.

[0055] According to one embodiment of this application, the method further includes:

[0056] Upon receiving a stop signal from the field generating mechanism, the field generating mechanism is stopped;

[0057] After confirming that the field generating mechanism has stopped, the refrigeration mechanism is started.

[0058] According to one embodiment of this application, the step of stopping the field generating mechanism upon receiving a stop signal from the field generating mechanism specifically includes:

[0059] Upon receiving a stop signal from the field generating mechanism, the first control valve is closed;

[0060] The step of starting the refrigeration mechanism after determining that the field generating mechanism has stopped specifically includes:

[0061] If the first control valve is determined to be closed, the second control valve is opened.

Detailed Implementation

[0085] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this application, but should not be used to limit the scope of this application.

[0086] In the description of the embodiments of this application, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0087] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. 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. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0088] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0089] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0090] Refrigeration equipment such as refrigerators, cold storage rooms, freezers, or freezers can lower the temperature of the storage space inside the cabinet to a very low level (for example, the freezer compartment of a regular household refrigerator can be kept at around -15°C, or even -22°C). This reduces the activity of cells or microorganisms on the surface of items stored in the freezer compartment, extends the storage time of the items, and can effectively improve people's quality of life.

[0091] To extend the shelf life of goods, or to store items that require freezing at extremely low temperatures (typically around -40°C), cryogenic refrigeration equipment has emerged in related technologies. Cryogenic refrigeration refers to the method of freezing and storing goods by lowering the temperature of the storage space in a refrigerator, cold storage, freezer, or freezer to a very low level (e.g., -40°C, -60°C, -80°C, or even -120°C). This allows for the storage of items with specific temperature requirements or extends their shelf life.

[0092] It's understandable that opening the door of a refrigeration unit is sometimes necessary when storing items, such as when putting items into or taking items out of the storage compartment. When the door is open, the storage compartment is exposed to the outside environment, allowing warm, humid air to easily enter. Since the storage compartment is cooler, the water vapor carried by the warm, humid air condenses and forms frost on the inner walls, reducing the refrigeration effect and hindering the preservation of items.

[0093] Currently, the process typically involves circulating air into the storage space to sublimate the frost on the inner walls of the storage space into water vapor, which is then carried by the circulating air through a cooler evaporator and condenses. The evaporator is then periodically heated to suppress frost, thus achieving the desired frost-suppressing effect.

[0094] However, due to the extreme temperatures within the storage space of cryogenic refrigeration equipment, the temperature of the circulating air drops rapidly upon entering the storage space. It can be understood that the saturation of water vapor in the air is positively correlated with temperature; that is, the higher the temperature, the greater the water vapor content in the air, and the lower the temperature, the lower the water vapor content. Within the storage space of cryogenic refrigeration equipment, the amount of frost that the circulating air can remove or sublimate at extremely low temperatures is limited, resulting in a poor defrosting effect on the cryogenic refrigeration equipment.

[0095] In related technologies, a refrigerated transport system is provided, comprising a container having a doorway equipped with at least one door; a refrigeration system including a first reversible fan for driving air along an airflow path and a heat exchanger for cooling air along the airflow path; and a second fan positioned to drive an air curtain flow downward through the doorway in at least one operating mode. This method, by using the second fan to form an air curtain flow of air from the external environment at the doorway, reduces the amount of air from the external environment entering the refrigerated space, thereby reducing frost formation in the refrigerated space.

[0096] However, in related technologies, the air curtain has limited effect on blocking air from the external environment, and some air still enters, causing frost to form on the inner wall of the cabinet, which affects the cooling effect.

[0097] Figure 1 This is an exploded structural diagram of the housing structure of the refrigeration equipment provided in the embodiments of this application. Figure 2 This is a front view of the housing structure of the refrigeration equipment provided in the embodiments of this application. Figure 3 It is along Figure 2 A cross-sectional view along line AA in the middle.

[0098] Reference Figures 1-3As shown in the figure, this application embodiment provides a cabinet structure 10 for a refrigeration device, including: an inner liner 110 and a door 120.

[0099] Specifically, in the embodiments of this application, reference is made to Figure 3 As shown, a storage space 111 can be formed inside the inner liner 110. It is understood that the inner liner 110 can be made of materials such as stainless steel or aluminum alloy. In some examples, the inner liner 110 can also be made of rigid plastic. It is also understood that storage partitions, drawers, or storage compartments can typically be provided in the storage space 111. In some examples, the inner liner 110 can also be provided with decorative elements such as deodorizing boxes, germicidal lamps, lighting, or temperature control knobs. This is not limited in the embodiments of this application. It is also understood that a scratch-resistant protective layer can be provided on the inner wall of the inner liner 110.

[0100] In this embodiment, the refrigeration equipment can specifically be a refrigerator, cold storage, freezer, refrigerated transport vehicle, or freezer, etc. As a specific example, a refrigerator is used as an example in this embodiment.

[0101] Typically, referencing Figure 3 As shown, an opening 112 may be provided on one side of the inner liner 110, and the opening 112 is connected to the storage space 111. Therefore, it can also be understood that the storage space 111 has an opening 112 on one side. This facilitates placing items into the storage space 111 or retrieving items from the storage space 111.

[0102] It is understandable that, in order to ensure the cooling effect of the refrigeration equipment, the items in the storage space 111 need to be effectively stored. Typically, a door 120 is provided at the opening 112 for sealing the opening. Therefore, a sealing strip / sealing ring is usually provided on the side of the door 120 facing the storage space 111; when the door 120 closes the opening 112, the sealing strip / sealing ring is pressed against the edge of the opening 112 by the door 120. For example, it is pressed against the edge of the inner liner 110 or against the frame of the refrigeration equipment. This achieves the sealing of the storage space 111, ensuring a low-temperature environment within the storage space 111.

[0103] During the refrigeration process, the storage compartment 111 is in a low-temperature environment, and the air inside the storage compartment 111 is also low-temperature air. The water vapor content in the low-temperature air is small, making it less prone to frost formation. However, when the door 120 is opened, warm and humid air from the outside environment enters the storage compartment 111 and quickly condenses and frosts under the low temperature of the storage compartment 111, causing frost to form on the inner wall of the inner liner 110 and reducing the refrigeration effect of the refrigeration equipment.

[0104] Therefore, referring to Figure 1 As shown, the housing structure 10 of the refrigeration equipment provided in this embodiment of the application also includes a field generation mechanism.

[0105] In this embodiment of the application, at least a portion of the field generating mechanism is disposed at the opening 112, and the field generating mechanism is used to interact with the first cold source 140 ( Figure 1 (Not shown in the image) is connected; the field generating mechanism is used to form a field on the side of the door 120 facing the opening 112, at least along the cross-sectional direction of the opening 112, to prevent water vapor from entering the storage space 111.

[0106] This can be understood as a field that prevents water vapor from entering the storage space 111, specifically an airflow field (which may also be called an air curtain in some examples), an electric field, or a microwave field, etc.

[0107] In this embodiment, a field generating mechanism is provided at the opening 112 and connected to the first cold source. Thus, when the door 120 of the refrigeration equipment is opened, the field generating mechanism can form a field that blocks water vapor in the cross-sectional direction of the opening 112. Specifically, the field can cause humid air or water vapor in the humid air to move directionally along the direction of the field and condense and settle at the first cold source 140. This prevents humid air from penetrating into the storage space 111 and reduces the movement of water vapor into the storage space 111. In other words, it can block humid air from the environment, reduce the amount of water vapor entering the storage space 111, effectively prevent frost formation on the inner wall of the storage space 111, and improve the refrigeration effect of the refrigeration equipment.

[0108] In some optional examples of the embodiments of this application, reference is made to Figures 1-3 As shown, the airflow generating mechanism may include an airflow generating mechanism, which can generate an airflow field or air curtain along the cross-sectional direction of the opening 112. It is understood that the airflow generating mechanism typically has an airflow outlet, such as an air outlet, air inlet / outlet, etc. The airflow generated by the airflow generating mechanism forms an airflow field or air curtain along the cross-sectional direction of the opening 112 through the airflow outlet. Therefore, in this embodiment, the airflow outlet can be located on the side of the door 120 facing the storage space 111.

[0109] It is understood that the airflow port has a guiding effect on the flow direction of the airflow. In this embodiment, the orientation of the airflow port can be along the cross-sectional direction of the opening 112, for example, parallel or approximately parallel to the cross-sectional direction of the opening 112. This ensures that the airflow generated by the airflow field generating mechanism can at least form an airflow field or wind curtain in the cross-sectional direction of the opening 112.

[0110] It is also understandable that the airflow generating mechanism is connected to the first cold source. Therefore, the airflow or air curtain generated by the airflow generating mechanism through the airflow port is a low-temperature airflow or low-temperature air curtain. In this way, when the door 120 of the refrigeration equipment is opened, the humid and hot air in the external environment will be blocked by the airflow on the one hand, and the water vapor in the humid and hot air will be condensed by the low-temperature airflow on the other hand, which can effectively reduce the occurrence of humid and hot air in the external environment penetrating into the storage space 111.

[0111] In this embodiment, an airflow field is formed in the cross-sectional direction of the opening 112. In this way, the airflow field can block the movement of hot and humid air from the external environment into the storage space 111, thus blocking the hot and humid air. On the other hand, the airflow field can quickly carry away the hot and humid air, preventing water vapor from accumulating at the opening, blocking and reducing the amount of water vapor entering the storage space, effectively preventing frost from forming on the inner wall of the storage space, and improving the cooling effect of the refrigeration equipment.

[0112] In one optional embodiment of this application, one end of the airflow generating mechanism is connected to a first cold source, thereby facilitating the generation of low-temperature airflow to form a low-temperature airflow field. It is understood that in this embodiment, the airflow outlet can specifically be an air outlet or an air inlet.

[0113] As a specific example, in this embodiment of the application, the other end of the airflow field generating mechanism 130 is provided with a first air outlet 131, that is, the airflow outlet includes the first air outlet 131.

[0114] Specifically, in this embodiment, the airflow generating mechanism can be a pipe structure that guides the flowing air, with one end of the pipe connected to the first cold source 140. Here, the first cold source 140 can be a heat exchanger, or in some examples, the first cold source 140 can also be an evaporator. It can be understood that when air flows through the first cold source 140, heat exchange occurs between the air and the first cold source 140, and the air is cooled, thereby forming low-temperature air. In specific configurations, in this embodiment, the first cold source 140 can be an external evaporator or a heat exchanger; that is, the first cold source 140 can be a separate component from the refrigeration equipment.

[0115] It is understood that refrigeration equipment usually has its own cold source, that is, the cold source that cools the storage space 111; in this embodiment, the pre-condensing mechanism 130 can also be connected to the cold source of the refrigeration equipment itself; that is, in this embodiment, the first cold source 140 can also be the cold source of the refrigeration equipment itself, that is, the first cold source 140 can be set inside the refrigeration equipment.

[0116] In this embodiment of the application, the other end of the pipe structure is the first air outlet 131, which can be specifically set on the side of the door 120 facing the storage space 111; that is, the first air outlet 131 can be set at the opening 112; in this way, when the pipe structure sends out flowing cold air from the first air outlet 131, the cold air blows outward at the first air outlet 131, thereby forming a flowing low-temperature airflow in the cross-sectional direction of the opening 112, that is, forming an airflow field or air curtain.

[0117] In a specific configuration, the air outlet 131 can be directed towards the opening 112, and the angle formed between the air outlet direction and the cross-sectional direction of the opening 112 is an acute angle. In this way, the cold air blown out from the first air outlet 131 has a certain component in the cross-sectional direction of the opening 112, thereby forming an airflow field or air curtain along the cross-sectional direction of the opening 112.

[0118] The cabinet structure 10 of the refrigeration equipment provided in this application embodiment is provided with an airflow generating mechanism 130. One end of the airflow generating mechanism 130 is connected to the first cold source 140. The other end of the airflow generating mechanism 130 is provided with a first air outlet 131. The first air outlet 131 is provided on the side of the door 120 facing the storage space 111, and the air outlet 131 is kept so that the air outlet direction can form a condensation air curtain at least along the cross-sectional direction of the opening 112. In this way, when the door 120 is opened, the water vapor contained in the humid and hot air in the external environment will be blocked by the airflow field or air curtain, which can effectively reduce the penetration of humid and hot air into the storage space 111, thereby reducing the amount of water vapor entering the storage space 111 and thus reducing the frost formation on the inner wall of the storage space 111. In addition, in this embodiment, since the airflow field generating mechanism 130 is connected to the first cold source 140, the airflow field or air curtain is a low-temperature air curtain. In this way, the airflow field or air curtain can condense the outside air that may penetrate into the storage space 111, thereby reducing the moisture content in the air and effectively reducing the frost formation on the inner wall of the storage space 111, ensuring the cooling effect of the refrigeration equipment.

[0119] Figure 4 It is along Figure 2 A cross-sectional view along the BB line.

[0120] Reference Figure 4 As shown, as an optional example of an embodiment of this application, the first air outlet 131 is located on the first side of the opening 112, and the opening 112 direction of the first air outlet 131 faces the second side of the opening 112; wherein, the second side is opposite to the first side. That is, in this embodiment of the application, the axial direction of the first air outlet 131 is parallel to the cross-sectional direction of the opening 112. Specifically, refer to... Figure 4As shown in the embodiment of this application, the cross-sectional direction of the opening 112 can be... Figure 4 The direction indicated by the x-axis. Figure 4 As an example, the first air outlet 131 can be located on the left side of the opening 112, and the axis of the first air outlet 131 can be parallel to the x-direction. In some alternative examples, the first air outlet 131 can also be located on the right side of the opening 112. In specific configurations, the air outlet direction of the first air outlet 131 can be along the horizontal direction of the housing structure 10. In other possible examples, the air outlet direction of the first air outlet 131 can also be at an angle of less than 90° to the horizontal direction on the cross-section of the opening 112. In this embodiment, it is only necessary to ensure that the air outlet direction of the first air outlet 131 is on the cross-section of the opening 112.

[0121] Understandably, in some examples, the first air outlet 131 may also be located at the top of the inner liner 110. In this case, the air outlet 131 may be vertically downward or have an angle of less than 90° with the vertical direction.

[0122] This ensures that the flow direction of the low-temperature airflow blown out from the first air outlet 131 by the airflow field generating mechanism 130 is parallel to the cross-sectional direction of the opening 112; that is, it can form the airflow field intensity with the maximum airflow in the cross-sectional direction of the opening 112, which can play a good role in blocking and isolating the outside air. In addition, it can also improve the condensation effect of the outside air, effectively reduce the humid and hot air that penetrates into the storage space 111, reduce / reduce the frost on the inner wall of the storage space 111, and ensure the cooling effect of the refrigeration equipment.

[0123] In one optional example of the embodiments of this application, refer to Figure 1 and Figure 4 As shown, the airflow generating mechanism 130 includes a first air supply duct 132, which is located on one side of the inner liner 110. The first air supply duct 132 has a first air inlet 133, which is used to connect with the first cold source 140. The first air outlet 131 is located on the side of the first air supply duct 132 facing the opening 112.

[0124] Specifically, refer to Figure 4 As shown in the embodiment of this application, the first cold source 140 can be a cold source built into the refrigeration equipment itself (e.g., an evaporator). It can be understood that the evaporator of the refrigeration equipment is usually located on the side of the inner liner 110 facing away from the opening 112, thus facilitating the user to retrieve items from the opening 112. It can also be understood that the evaporator is located on the rear side of the inner liner 110 or the refrigeration equipment. In this embodiment, refer to... Figure 1 and Figure 4As shown, the first air supply duct 132 can be located on one of the left or right sides of the inner liner 110, or, in some alternative examples, the first air supply can be located on one of the upper or lower sides of the inner liner 110. This reduces the space required by the first air supply duct 132, thereby reducing the overall volume of the refrigeration equipment's housing structure 10.

[0125] Figure 5 yes Figure 1 A magnified schematic diagram of the structure at point C. Figure 6 yes Figure 4 A magnified schematic diagram of the structure at point D. Figure 7 yes Figure 4 A magnified schematic diagram of the structure at point E in the middle.

[0126] Continue to refer to Figure 1 and Figure 4 As shown, in some optional examples of embodiments of this application, the airflow generating mechanism 130 further includes a first return air duct 134, the first return air duct 134 having a second air inlet 135 (see reference). Figures 4-7 (as shown) and the second air outlet 136; the second air inlet 135 is arranged opposite to the first air outlet 131, and the second air outlet 136 is used to connect to the first cold source 140.

[0127] Specifically, in the embodiments of this application, reference is made to Figure 4 As shown, the first air supply duct 132 can be located on the left side of the inner liner 110, and the second air supply duct 163 can be located on the right side of the inner liner 110. It is understood that the specific positions of the first air supply duct 132 and the second air supply duct 163 can be interchanged, and this is not limited in the embodiments of this application.

[0128] It is understood that, as described in the foregoing embodiments, the air outlet direction of the first air outlet 131 is along the cross-sectional direction of the opening 112; therefore, in this embodiment, the air inlet direction of the first air inlet 133 can also be along the cross-sectional direction of the opening 112. In specific configurations, the axial direction of the first air outlet 131 and the axial direction of the first air inlet 133 can be collinear or approximately collinear. This allows the cold airflow blowing from the first air outlet 131 to connect with the first air inlet 133, effectively preventing the airflow field or air curtain from becoming scattered or turbulent.

[0129] As a specific example of an embodiment of this application, the axial direction of the first air outlet 131 can be set in the horizontal direction, and the axial direction of the first air inlet 133 can also be set in the horizontal wind direction.

[0130] In this embodiment, a first return air duct 134 is provided, with its second air inlet 135 positioned opposite to the first water outlet of the first supply air duct 132. Furthermore, the second air outlet 136 of the first return air duct 134 is connected to the first cold source 140. This creates a complete circulation loop within the entire airflow generating mechanism 130, continuously generating a strong condensing airflow field or air curtain, thus ensuring continuous isolation from the humid and hot air in the external environment. The second air inlet 135 is positioned opposite to the first air outlet 131, allowing the airflow from the first air outlet 131 to return through the second air inlet 135. This creates a stable airflow field or air curtain at the opening 112, improving the stability of the airflow field or air curtain.

[0131] Furthermore, in this embodiment, by forming a complete circulation loop, after an airflow field or air curtain is formed at the opening 112 of the storage space 111, a negative pressure area will be formed at this location due to the high airflow velocity of the airflow field or air curtain. After the door 120 is opened, the humid and hot air from the external environment that permeates into the storage space 111 will be carried away by the airflow field or air curtain under negative pressure, and will enter the first return air duct 134 from the second air inlet 135, and then enter the first cold source 140 from the second air outlet 136. The first cold source 140 can condense and dehumidify the water vapor in the air, thereby reducing the water vapor content in the air, effectively preventing frost from forming on the inner wall of the storage space 111, and improving the cooling effect of the refrigeration equipment.

[0132] In one optional example of the embodiments of this application, refer to... Figure 4 As shown, the airflow generating mechanism 130 also includes a fan 150, which is located on the airflow path of the airflow field; the fan 150 is used to drive the airflow to flow in the duct so as to form an airflow field or air curtain at the opening 112.

[0133] Specifically, refer to Figure 4 As shown in the embodiments of this application, the fan 150 can be disposed in the cavity of the first air supply duct 132; or, in some other examples, the fan 150 can also be disposed in the cavity of the first return air duct 134.

[0134] Of course, in some examples, the fan 150 can also be set in other locations, for example, the fan 150 can be set at the location where the first supply air duct 132 is connected to the first cold source 140, or the fan 150 can be set at the location where the first return air duct 134 is connected to the first cold source 140.

[0135] In this embodiment of the application, a fan 150 is provided on the airflow path of the airflow field or air curtain (e.g., the first air supply duct 132, the second air supply duct 163 and / or the first cold source 140) to drive the airflow. This can enhance the strength of the air curtain and effectively reduce the amount of humid and hot air from the external environment penetrating into the storage space 111.

[0136] As a specific example of an embodiment of this application, refer to Figure 4 As shown, a fan 150 is installed in both the first supply air duct 132 and the first return air duct 134. Thus, the fan 150 in the first supply air duct 132 drives the air blown from the first air outlet 131, ensuring the airflow velocity from the first air outlet 131; the fan 150 in the first return air duct 134 creates negative pressure at the second air inlet 135, thereby rapidly increasing the flow velocity of the condensation air curtain at the second air inlet 135. This ensures the stability of the entire air curtain's flow velocity and the strength of the air curtain.

[0137] Understandable, refer to Figure 3 As shown, the first cold source 140 is typically located on the lower side or bottom of the inner liner 110. Therefore, in this embodiment, both the first air inlet 133 and the second air outlet 136 can be located at the bottom of the inner liner 110. Thus, when the fan 150 drives the airflow to flow within the first supply air duct 132; or when the fan 150 drives the airflow to flow within the first return air duct 134, the air velocity at the bottom of the first supply air duct 132 is greater than the air velocity at the top of the first supply air duct 132; or, the air velocity at the bottom of the first return air duct 134 is greater than the air velocity at the top of the first return air duct 134.

[0138] In some optional examples of the embodiments of this application, reference is made to Figure 1 As shown, the first air supply duct 132 can be designed as a trapezoidal structure, specifically, the cross-section of the first air supply duct 132 gradually decreases or shrinks along the vertical direction upwards; this ensures that the air velocity blown out from the first air outlet 131 along the entire vertical direction of the first air supply duct 132 is the same or approximately the same; thus ensuring that the strength of the pre-condensing air curtain is consistent throughout the cross-section of the opening 112, effectively isolating the humid and hot air from the external environment. It is understood that in this embodiment, the first return air duct 134 can be configured in the same or similar manner as the first air supply duct 132, and specific details can be found in the detailed description of the first air supply duct 132. Further details are omitted in this embodiment.

[0139] Figure 8 yes Figure 4 A magnified schematic diagram of the structure at point F in the middle. Figure 9 yes Figure 4 A magnified schematic diagram of the structure at point G in the middle.

[0140] Reference Figure 8 and Figure 9 As shown, in some optional examples of embodiments of this application, at least one of the first air inlet 133 and the second air outlet 136 is provided with a first control valve 137, which is used to cut off the airflow path of the airflow field.

[0141] Specifically, in the embodiments of this application, the first control valve 137 can be a solenoid valve, an electrically controlled valve, etc. In a specific setting, the first control valve 137 can be set at the first air inlet 133; or, in some examples, the first control valve 137 can also be set at the second air outlet 136; or, in some other optional examples, a first control valve 137 can be set at the first air inlet 133, and another first control valve 137 can be set at the second air outlet 136.

[0142] In this embodiment, a first control valve 137 is provided at at least one of the first air inlet 133 and the second air outlet 136. This allows for selective activation or deactivation of the airflow generation mechanism 130. Consequently, the airflow generation mechanism 130 can be activated only when the door 120 needs to be opened, effectively reducing energy consumption.

[0143] In one optional example of this application embodiment, a trigger switch (not shown in the figure) is provided on the door 120, and the trigger switch is used to send a trigger signal; in this application embodiment, the airflow generating mechanism 130 can be started or stopped according to the trigger signal. As a specific example, the first control valve 137 can be opened or closed according to the trigger signal.

[0144] Specifically, in this embodiment, the trigger switch includes any one of an electronic lock, an infrared sensor, a radar sensor, or a camera. Of course, in other optional examples of this embodiment, the trigger switch may be a combination of multiple electronic locks, infrared sensors, radar sensors, or cameras.

[0145] In this embodiment, a trigger switch is provided on the door 120. When the user needs to open the door 120, the trigger switch is activated and sends a trigger signal to the first control valve 137 of the airflow field generating mechanism 130. This allows the first control valve 137 to open in a timely manner, thereby forming an airflow field or air curtain at the opening 112. Furthermore, when the user closes the door 120, the first control valve 137 can be closed promptly based on the trigger signal from the trigger switch, stopping the operation of the airflow generating mechanism 130 and saving energy.

[0146] Reference Figure 3As shown, in some optional examples of embodiments of this application, the housing structure 10 further includes a refrigeration mechanism 160, the third air outlet 161 and the third air inlet 162 of the refrigeration mechanism 160 are both connected to the storage space 111; the refrigeration mechanism 160 is used to deliver circulating refrigerated air to the storage space 111 through the third air outlet 161 and the third air inlet 162.

[0147] It is understood that in this embodiment of the application, the refrigeration mechanism 160 may be connected to the storage space 111 through components such as a compressor, evaporator and circulating air duct, and form a low-temperature circulating airflow in the storage space 111 through the third air outlet 161 and the third air inlet 162, thereby cooling the items in the storage space 111; it can effectively create a freezing environment in the storage space 111.

[0148] Continue to refer to Figure 3 As shown, in an optional example of an embodiment of this application, the refrigeration mechanism 160 includes: a second cold source (not labeled in the figure), a second supply air duct, and a second return air duct.

[0149] Specifically, in the embodiments of this application, the second cold source can also be an evaporator or a heat exchanger. In specific settings, the second cold source can be the same as the first cold source 140 in the aforementioned embodiments; or, in some optional examples of the embodiments of this application, the second cold source can be the same as the first cold source 140 in the aforementioned embodiments.

[0150] In this embodiment, the second supply air duct 163 and the second return air duct 164 can also be pipe structures. The second supply air duct 163 and the second return air duct 164 can guide and direct the circulating cooling air. That is, the circulating cooling air is introduced into the storage space 111 through the third air outlet 161 located at one end of the second supply air duct 163, and then the cooling air is circulated to the second cold source through the third air inlet 162 and the second return air duct 164. In this way, it is convenient to cool down the storage space 111, and the items in the storage space 111 can be effectively refrigerated / frozen.

[0151] In some optional examples of embodiments of this application, at least one of the second supply air duct 163 and the second return air duct 164 is provided with a second control valve 165, which opens or closes according to a trigger signal.

[0152] Specifically, in this embodiment, the second control valve 165 may be the same as or similar to the first control valve 137. For details, please refer to the foregoing detailed description of the first control valve 137. It will not be repeated in this embodiment.

[0153] In this embodiment, a second control valve 165 is provided on at least one of the second supply air duct 163 and the second return air duct 164. When the door 120 is opened, the second control valve 165 can be closed to cut off the refrigeration system, i.e., to suspend the operation of the refrigeration system. This effectively prevents the formation of negative pressure in the storage space 111 from drawing in humid and hot air from the external environment. In addition, it can also ensure the stability of the airflow field or air curtain flow and improve the isolation effect of the airflow field or air curtain on humid and hot air from the external environment.

[0154] Continue to refer to Figure 3 As shown, in some optional examples of embodiments of this application, the third air outlet 161 is located at the top of the inner liner 110, and the third air inlet 162 is located at the bottom of the inner liner 110. Thus, referring to... Figure 3 As shown, circulating cooling air is formed in the storage cavity. Figure 3 The airflow direction indicated by the middle arrow is cyclic; that is, the circulating cooling air flows downward from the top of the storage space 111, which conforms to the fluid dynamics principle of cold air flowing downward, and can fully cool the storage space 111.

[0155] Reference Figure 1 and Figure 4 As shown, in an optional example of this embodiment, the first return air duct 134 and the first supply air duct 132 are disposed opposite to each other on both sides of the inner liner 110. This makes the overall structure of the housing 10 more compact, effectively reducing the space occupied by the refrigeration equipment.

[0156] Figure 10 This is a schematic diagram of the cabinet structure of the refrigeration equipment provided in this application embodiment when the door is in the open state. Figure 11 This is a front view of the cabinet structure door of the refrigeration equipment provided in this embodiment of the application when it is in the open state. Figure 12 yes Figure 10 A magnified schematic diagram of the structure at point H in the middle.

[0157] In a specific example of an embodiment of this application; refer to Figure 10 and Figure 11 As shown, the first air outlet 131 (not shown in the figure) is arranged along the height direction of the inner liner 110 to form an airflow field or air curtain along the width direction of the opening 112. Wherein, Figure 10 The direction of the second air inlet 135 is shown as an example. It can be understood that in this embodiment, the first air outlet 131 and the second air inlet 135 are arranged opposite to each other. Therefore, the arrangement of the first air outlet 131 is the same as that of the second air inlet 135.

[0158] In this embodiment, the first air outlet 131 is positioned along the height of the inner liner 110, thus forming an airflow field or air curtain along the width of the opening 112 (e.g., refer to...). Figure 10 and Figure 11 The hollow arrow indicates the direction of airflow (forming a pre-condensing air curtain), which can shorten the travel distance of the airflow field or air curtain; thus ensuring the strength of the airflow field or air curtain, which can reduce the amount of humid and hot air from the external environment penetrating into the storage space 111, effectively suppressing the frost formation on the inner wall of the storage space 111.

[0159] Understandably, in some examples, the airflow direction of the formed airflow field or wind curtain can also be... Figure 10 The hollow arrows indicate the opposite direction.

[0160] It is understood that in this embodiment of the application, the first air outlet 131 covers the opening 112 along the height direction of the inner liner 110. In this way, an airflow field or air curtain can be formed on the entire cross-section of the opening 112, which can effectively block the hot and humid air in the external environment.

[0161] In one optional example of the embodiments of this application, refer to Figure 10 and Figure 12 As shown, the first air outlet 131 ( Figure 10 The image shows a second air inlet 135 (which, as can be understood, is arranged in the same way as the first air outlet 131), and there are multiple first air outlets 131 arranged along the height of the inner liner 110. This makes the generated airflow field or air curtain more stable and uniform, and can effectively block the humid and hot air in the external environment.

[0162] Figure 13 It is along Figure 11 Sectional view of line II in the middle.

[0163] In one specific application scenario of this application embodiment, referring to Figure 13 As shown, when the user opens the door 120, the trigger switch on the door 120 can be an electronic lock; when the electronic lock is triggered, the first control valve 137 opens and the second control valve 165 closes, and the low-temperature airflow used to form an airflow field or air curtain is blown out from the first air outlet 131 and enters the first return air duct 134 from the second air inlet 135, and then flows back to the first cold source 140; after running for a certain period of time (for example, after a stable low-temperature airflow field is formed at the opening 112), the electronic lock on the door 120 unlocks and emits a prompt sound; at this time, the user can open the door 120; see reference Figure 13 The solid arrow indicates the direction of airflow; the airflow field or wind curtain continues to circulate; the warm, humid air in the external environment flows along... Figure 13The direction indicated by the dashed arrow is drawn into the airflow field or air curtain by the negative pressure at the airflow field or air curtain, and condensed by the low temperature airflow field; the humid and hot air enters the first cold source 140 along the airflow direction of the airflow field or air curtain, and is condensed again, thereby reducing the water vapor content in the air, which can effectively prevent water vapor in the humid and hot air from entering the storage space 111 and causing sublimation and frost, thus improving the cooling effect of the refrigeration equipment.

[0164] In an optional example of the embodiments of this application, the field generating mechanism can also be an electric field generating mechanism. The two plates of the electric field generating mechanism are arranged opposite to each other on both sides of the opening 112, so that after a voltage is applied to the two plates, an electric field can be formed along the cross-sectional direction of the opening.

[0165] It is understandable that when the user opens the door 120 of the refrigeration equipment, the humid and hot air in the external environment will permeate and move into the storage space 111. After the humid and hot air enters the electric field, the electric field can excite the water vapor molecules in the humid and hot air, causing the water molecules to become charged. Under the action of the electric field, the charged water molecules move directionally along the direction of the electric field strength, and the water vapor will not enter the storage space 111, thus playing a good blocking role against water vapor in the external environment.

[0166] In some specific examples, the electric field generating mechanism may also be equipped with an air duct, which may be connected to the first cold source 140. In addition, an array of vents may be provided on the two plates, so that cold air can be delivered into the electric field through the vents, thereby condensing the water vapor that permeates into the storage space 111, thereby reducing the amount of water vapor entering the storage space.

[0167] It is understandable that the electrode plate can also be multiple small electrode plates arranged at intervals along the edge of the opening 112, and cold air can be blown out from the gap between two adjacent small electrode plates.

[0168] As another optional example of the embodiments of this application, the field generating mechanism can also be a microwave field generating mechanism. In a specific setting, the microwave generator of the microwave field generating mechanism is arranged along the cross-sectional direction of the opening 112. In this way, when the microwave generator generates microwave oscillation, the generated microwave field can propagate along the cross-sectional direction of the opening, thereby forming a microwave field in the cross-sectional direction of the opening.

[0169] It is understood that in the embodiments of this application, the microwave field generating mechanism can be set in the same or similar direction as the electric field generating mechanism. That is, the microwave field generating mechanism can also be set in conjunction with the first cold source 140 and form a low-temperature airflow in the microwave field through the air supply duct or return air duct, thereby condensing water vapor in the external environment.

[0170] In this way, by using a microwave field generating mechanism to generate a microwave field along the cross-sectional direction of the opening, when the door 120 is opened, the microwave field drives and propels the water vapor in the hot and humid air outside, causing the water vapor to move directionally along the direction of the microwave field, thereby reducing the penetration of water vapor into the storage space and effectively preventing frost formation in the storage space.

[0171] It is also understood that, in some optional examples of the embodiments of this application, one end of the airflow generating mechanism 130 is used to connect to the first cold source, and the airflow port at the other end of the airflow generating mechanism 130 can be the second air inlet.

[0172] In other words, in this embodiment, the airflow generating mechanism 130 may also include only one return air duct, one end of which is the second air inlet 135, and the other end of which is connected to the first cold source. Thus, when the door 120 is opened, the airflow generating mechanism is activated, drawing air into the opening 112 through the second air inlet, thereby forming an airflow field at the opening 112.

[0173] Continue to refer to Figure 13 As shown in the illustration, this application also provides a refrigeration device, including a housing structure 10 and an outer shell 20 as provided in the foregoing embodiments of this application, wherein the housing structure 10 is disposed within the outer shell 20. The outer shell 20 may be made of a metal shell or rigid plastic, etc.

[0174] In an optional embodiment of this application, the refrigeration device further includes a thermal insulation layer 30, which is located between the outer shell 20 and the box structure 10. Specifically, in this embodiment, the thermal insulation layer 30 can be disposed between the airflow generating mechanism 130 and the outer shell 20; thus, the thermal insulation layer 30 can insulate the storage space 111 of the inner liner 110 on the one hand, and on the other hand, it can also insulate the airflow generating mechanism 130 to ensure the temperature of the airflow field. It can be understood that in this embodiment, the pipe walls of the first air outlet 131 and the second air inlet 135 can be embedded in the thermal insulation layer 30.

[0175] In some optional examples of the embodiments of this application, the insulation layer 30 may be made of materials such as foamed cotton or foamed foam.

[0176] Figure 14 This is a flowchart illustrating the implementation of the defrosting method for the refrigeration equipment provided in this application embodiment. (Refer to...) Figure 14 As shown, this application embodiment also provides a defrosting method for a refrigeration device, wherein the refrigeration device can be the refrigeration device provided in the foregoing embodiments of this application, that is, the refrigeration device includes:

[0177] The inner liner 110 has a storage space 111, and an opening 112 is provided on one side of the storage space 111.

[0178] Door 120 is located at opening 112 and is used to close opening 112.

[0179] A field generating mechanism is provided at least partly at the opening 112, and one end of the field generating mechanism is used to connect to the first cold source 140; the field generating mechanism is used to form a field on the side of the door 120 facing the opening 112 at least along the cross-sectional direction of the opening 112 to prevent water vapor from entering the storage space 111.

[0180] Specifically, in the embodiments of this application, the description of the refrigeration equipment can be referred to the detailed description of the foregoing embodiments of this application, and will not be repeated here. The defrosting method of the refrigeration equipment includes the following steps:

[0181] Step 1401: Upon receiving a start signal, the field generating mechanism is activated to form a field at least along the cross-sectional direction of the opening 112 to prevent water vapor from entering the storage space 111.

[0182] Specifically, in this embodiment, the pre-condensation mechanism can operate continuously during the operation of the refrigeration equipment (e.g., a refrigerator). For example, the pre-condensation mechanism 130 starts working after the refrigerator is connected to the power grid and powered on. In this case, the power-on signal of the refrigerator can be understood as a start signal.

[0183] In some possible examples, the field generating mechanism can also be controlled to start and stop via control signals. For example, in some examples, a control circuit board is typically installed inside the refrigerator. The control circuit board can be an integrated circuit board or a printed circuit board (PCB). The control circuit board can be equipped with a controller, which can be electrically connected to the field generating mechanism to send control signals to the field generating mechanism to control its start and stop.

[0184] It is understood that the defrosting method of the refrigeration equipment provided in this application embodiment has the same or corresponding technical features as the cabinet structure 10 of the refrigeration equipment provided in the foregoing embodiment of this application. Therefore, the embodiments of this application have the same or similar timely effects as the foregoing embodiments. For details, please refer to the detailed description in the foregoing embodiments. This will not be repeated in the embodiments of this application.

[0185] In some optional examples of the embodiments of this application, a trigger switch is provided on the door 120. The trigger switch is used to issue a trigger signal, wherein the start signal may include the trigger signal. Specifically, in the embodiments of this application, the trigger switch on the door 120 may be the same as the trigger switch in the aforementioned embodiments. Step 1041, activating the field generating mechanism upon receiving the start signal, specifically includes:

[0186] Upon receiving a trigger signal, the field generation mechanism is activated.

[0187] In other words, in this embodiment of the application, the trigger switch sends a trigger signal when triggered, for example, when the electronic lock in the aforementioned embodiment is touched and opened by the user; or when the infrared sensor in the aforementioned embodiment detects that the user is preparing to open the refrigerator door 120; or when the radar sensor in the aforementioned embodiment detects that the user is preparing to open the refrigerator. Here, the trigger signal can specifically be sent to the controller in the aforementioned embodiment; the controller processes and judges the trigger signal; and then sends a control signal to start the pre-condensation mechanism 130.

[0188] In this way, the refrigeration equipment can promptly activate the field generation mechanism when the door 120 is opened, and form a field in the cross-sectional direction of the opening. This effectively blocks, transports, and condenses water vapor that permeates from the external environment into the storage space, thereby reducing the occurrence of water vapor entering the storage space and preventing frost from forming on the inner wall of the storage space, thus improving the refrigeration effect of the refrigeration equipment.

[0189] Figure 15 This is another implementation flowchart of the defrosting method for the refrigeration equipment provided in the embodiments of this application.

[0190] As an optional example of an embodiment of this application, the door 120 is provided with a locking element for locking the door 120 and the housing 20 of the refrigeration equipment. Specifically, in this embodiment, the locking element may be an electronic lock as described in the foregoing embodiments. Of course, in some optional examples, the locking element may also be other types of locking mechanisms.

[0191] As an optional example of an embodiment of this application, refer to Figure 15 As shown in the embodiment of this application, the defrosting method for a refrigeration device specifically includes the following steps:

[0192] Step 1501: Upon receiving a start signal, the field generation mechanism is activated.

[0193] Step 1502: Whether the first operating state of the monitoring field generation mechanism has reached the first preset condition.

[0194] Specifically, in this embodiment, the first preset condition can be set according to actual needs. For example, in some examples, it can be monitored whether the temperature at opening 112 is less than or equal to a preset temperature threshold. It is understood that, usually after the controller receives the trigger signal, it controls the pre-condensing device to run; since the field generating mechanism is always in a stopped state, the temperature in the air duct connected to the first cold source 140 of the field generating mechanism may be at a relatively high temperature, for example, higher than the preset pre-condensing temperature. At this time, the temperature at opening 112 can be monitored. When the temperature at opening 112 is less than or equal to the temperature threshold, it proves that the field (e.g., airflow field, electric field, or microwave field) formed at this time meets the conditions for blocking and pre-condensing the humid and hot air in the external environment, that is, the first preset condition is met.

[0195] In some other possible examples of embodiments of this application, the first operating time of the field generating mechanism can also be monitored. For example, after the field generating mechanism is started, the controller begins timing and compares the timing with a first preset time length. When the first operating time length is greater than or equal to the first preset time length, it can be determined that the first preset condition has been met.

[0196] Step 1503: When the first operating state of the on-site generating mechanism reaches the first preset condition, the locking element is unlocked. This facilitates the user opening the door. Here, when the locking element is unlocked, the user can be notified by voice or sound that the locking element has been unlocked.

[0197] In this embodiment, a locking element is provided on the door 120 to lock the door 120 to the outer casing 20 of the refrigeration equipment. The locking element is unlocked after the first operating state of the field generating mechanism reaches the first preset condition. In this way, the user can open / unlock the door 120 of the refrigeration equipment only after the field generated by the field generating mechanism along the cross-sectional direction of the opening 112 is stable. This can effectively ensure that the field generated by the field generating mechanism blocks and condenses the humid and hot air in the external environment, effectively reduce the occurrence of water vapor entering the storage space, effectively prevent the inner wall of the storage space from frosting, and improve the refrigeration effect of the refrigeration equipment.

[0198] Figure 16 This is another implementation flowchart of the defrosting method for the refrigeration equipment provided in the embodiments of this application.

[0199] Reference Figure 16 As shown, in some optional examples of embodiments of this application, the defrosting method of the refrigeration equipment includes the following steps:

[0200] Step 1601: Upon receiving a start signal, the field generation mechanism is activated.

[0201] Step 1602: Whether the first operating state of the monitoring field generation mechanism has reached the first preset condition.

[0202] Step 1063: When the first operating state of the field generating mechanism reaches the first preset condition, the locking component is unlocked.

[0203] Step 1064: Upon receiving the locking signal from the locking element, monitor whether the second operating state of the field generating mechanism has reached the second preset condition. Specifically, in this embodiment, the closing signal of the door 120 can also be issued by a trigger switch; for example, the locking signal of the locking element can serve as the closing signal of the door 120.

[0204] In other alternative examples, the aforementioned infrared sensor, radar sensor (e.g., ultrasonic radar sensor), or camera may send a closing signal to the controller for the door 120. For example, the infrared sensor detects that the user has closed the door and left, or the radar sensor detects that the user has closed the door and left, etc.

[0205] As can be understood from the detailed description in the foregoing embodiments of this application, when the door 120 of the refrigeration equipment is opened, the humid and hot air from the external environment is brought into the field by the field generating mechanism and enters the return air duct under the influence of the field. In this way, water vapor in the humid and hot air can condense and settle at the first cold source 140, thereby reducing the water vapor content and effectively preventing water vapor from entering the storage space 111. However, water vapor in the humid and hot air usually cannot be completely condensed and removed at once; therefore, in this embodiment of the application, the air humidity at the opening 112 can be monitored to determine whether the air humidity at the opening 112 is less than or equal to a preset humidity threshold. Here, the preset humidity threshold can specifically be the saturated water vapor content of the pre-condensing air curtain at the pre-condensing temperature.

[0206] As another optional example of this application, after receiving the closing signal, the controller can also generate a second operating time for the pre-condensing mechanism. That is, in this embodiment of the application, after the door 120 is closed, the pre-condensing mechanism 130 can continue to operate for a period of time, namely the second operating time. By determining whether the second operating time is greater than or equal to the second preset time length, it is determined whether the second operating state of the pre-condensing mechanism 130 has reached the second preset condition.

[0207] It is understood that in the embodiments of this application, the specific values ​​of the first preset time length and the second preset time length can be the same or different. For example, in some examples, the specific value of the first preset time length can be 30s, 1min or 2min; the specific value of the second preset time length can be 1min, 2min or 5min, etc.

[0208] In this way, the field generating mechanism can continue to operate for a period of time after the door 120 is closed, which can fully condense the water vapor in the humid and hot air of the external environment mixed with the field, thereby effectively reducing the amount of water vapor entering the storage space 111, effectively preventing the frost from forming on the inner wall of the storage space 111, and improving the cooling effect of the refrigeration equipment.

[0209] Step 1065: When the second operating state reaches the second preset condition, the field generation mechanism is stopped.

[0210] In a specific example of an embodiment of this application, the field generating mechanism includes an airflow field generating mechanism 130. The airflow outlet of the airflow field generating mechanism 130 is located on the side of the door 120 facing the storage space 111, and the airflow outlet is used to form an airflow field at least along the cross-sectional direction of the opening 112. Specifically, step 1603, monitoring whether the first operating state of the field generating mechanism reaches the first preset condition, further includes:

[0211] Monitor whether the temperature of the airflow inlet is less than or equal to a preset temperature threshold.

[0212] If the temperature is less than or equal to the preset temperature threshold, it is determined that the first operating state has reached the first preset condition.

[0213] It is understood that in some examples, step 1064 may specifically include monitoring the temperature and humidity of the airflow outlet, which may be the same as or similar to monitoring the opening 112. This will not be elaborated further in the embodiments of this application.

[0214] It is also understood that in some alternative examples of the embodiments of this application, the field generating mechanism can be an electric field generating mechanism, with two plates of the electric field generating mechanism disposed opposite to each other on both sides of the opening 112. In this case, it is possible to monitor whether the electric field strength is greater than or equal to a preset electric field strength. And if the electric field strength is greater than or equal to the preset electric field strength, it is determined that the first operating state has reached the first preset condition.

[0215] Furthermore, it can be understood that, as described in the foregoing detailed description of the embodiments of this application, the field generating mechanism can also be a microwave field generating mechanism. In this case, it is possible to monitor whether the oscillation frequency of the microwave field generating mechanism is greater than or equal to a preset oscillation frequency. And if the oscillation frequency is greater than or equal to the preset oscillation frequency, it is determined that the first operating state has reached the first preset condition.

[0216] As described in the foregoing optional examples of the embodiments of this application, the refrigeration device further includes a refrigeration mechanism 160, which is connected to the storage space 111 and is used to deliver circulating refrigeration air to the storage space.

[0217] In this embodiment of the application, step 1601, upon receiving a start signal, activates the field generating mechanism, specifically including:

[0218] Upon receiving a start signal, the refrigeration mechanism 160 is stopped. As described in the foregoing detailed description of the embodiments of this application, stopping the refrigeration mechanism 160 can specifically be achieved by closing the second control valve 165.

[0219] When it is determined that the refrigeration mechanism 160 has stopped, the field generating mechanism is started. Specifically, after the second control valve 165 is closed, it can return a closing signal to the controller. The controller can determine that the second control valve 165 has been closed based on the closing signal returned by the second control valve 165. At this time, the controller then controls the field generating mechanism to start.

[0220] In this embodiment, by setting the refrigeration mechanism 160 and the field generation mechanism of the refrigeration equipment to two independent operating conditions, when the door 120 of the refrigeration equipment is opened, it is possible to effectively prevent the circulating refrigeration air of the refrigeration mechanism from forming negative pressure in the storage space 111, thus preventing the intake of humid and hot air from the external environment into the storage space 111. This effectively reduces the amount of water vapor entering the storage space 111 and prevents frost from forming on the inner wall of the storage space 111, thereby improving the refrigeration effect of the refrigeration equipment. In addition, it also prevents the airflow from blowing into the storage space 111 at the opening, which would affect the user when retrieving items, thus improving the user experience.

[0221] It is understood that, as described in the foregoing embodiments of this application, the field generating mechanism in this application embodiment can be an airflow field generating mechanism 130. When the field generating mechanism is an airflow field generating mechanism 130, in this application embodiment, a first control valve 137 can be provided on the airflow path of the airflow field; for example, the first control valve 137 can be provided on a duct that guides and transports the airflow. In this case, starting the field generating mechanism can specifically involve opening the first control valve 137. For example, the controller sends a control signal to control the first control valve 137 to open, thereby putting the airflow field generating mechanism 130 into operation.

[0222] It is also understood that, in this embodiment of the application, since the refrigeration mechanism and the field generation mechanism are set as two independent operating conditions, the operation of the field generation mechanism needs to be stopped when the refrigeration mechanism needs to be put into operation.

[0223] In other words, in this embodiment, the field generating mechanism is stopped upon receiving a stop signal from it. This stop signal can be understood as a control signal issued by the controller in the aforementioned embodiments when the second operating state of the field generating mechanism reaches a second preset condition. Specifically, when the field generating mechanism is an airflow field generating mechanism 130, stopping the field generating mechanism can specifically involve closing the first control valve 137. Of course, when the field generating mechanism is an electric field generating mechanism or a microwave field generating mechanism, stopping the field generating mechanism can involve powering down (or de-energizing) the field generating mechanism.

[0224] After the field generating mechanism stops, the refrigeration mechanism 160 is activated. It is understood that after the field generating mechanism stops, it can return a stop signal to the controller, and the controller determines whether the field generating mechanism has stopped based on the returned signal. Specifically, in this embodiment, activating the refrigeration mechanism 160 can specifically involve opening the second control valve 165, thereby connecting the air duct of the refrigeration mechanism 160 to the storage space 111.

[0225] In other words, in this embodiment, the field generating mechanism stops operating while the refrigeration mechanism 160 is running. Alternatively, it can be understood that the refrigeration mechanism 160 is started after the field generating mechanism stops operating. This reduces energy consumption and lowers the load on the first cold source 140, ensuring refrigeration efficiency.
