Description

Technical Field

[0001] This application relates to refrigeration technology. In particular, it relates to a refrigerator. Background Technology

[0002] A frost-free refrigerator is a household appliance that uses a fan and air circulation system to achieve cooling. Unlike traditional direct-cooling refrigerators, frost-free refrigerators use an internal fan to evenly distribute cold air to all corners of the refrigerator, thus avoiding the problem of frost forming on food surfaces. This design not only improves cooling efficiency but also reduces the hassle of manual defrosting for users.

[0003] In related technologies, air-cooled refrigerators include a cabinet, an evaporator, and a heater. The evaporator generates cold energy, and after a period of cooling, frost will form on the evaporator. The heater is used to heat the evaporator, and the heat is transferred to the evaporator to melt the frost into water.

[0004] However, defrosting takes a long time and is inefficient. Utility Model Content

[0005] This application provides a refrigerator with high defrosting efficiency.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides a refrigerator, including:

[0008] The enclosure has an internal cavity;

[0009] Evaporator, located within the cavity, includes:

[0010] At least two support members are provided, and the at least two support members are spaced apart along a first direction;

[0011] A heat-conducting structure is located between two support members along the first direction.

[0012] Refrigeration piping, which passes through the supporting components and heat-conducting structures;

[0013] Fins are installed in the refrigeration piping.

[0014] The heater is located in the inner cavity, and it is in contact with the support and the heat-conducting structure.

[0015] The refrigerator provided in this application includes a cabinet, an evaporator, and a heater. The cabinet has an inner cavity, where the evaporator and heater are located. The evaporator includes at least two support members, a heat-conducting structure, refrigeration pipes, and fins. The at least two support members are spaced apart along a first direction. Along this first direction, the heat-conducting structure is located between the two support members. The refrigeration pipes pass through the support members and the heat-conducting structure, and the fins are disposed within the refrigeration pipes. The heater is in contact with both the support members and the heat-conducting structure. In this way, the heat from the heater can be transferred to the refrigeration pipes and fins through the support members and the heat-conducting structure. Compared to heat transfer through only the support members, this increases the heat transfer path, improves heat transfer efficiency, reduces defrosting time, and enhances defrosting efficiency. Furthermore, when the evaporator is operating, frost buildup is more severe in the central area. With the heat-conducting structure located between the two support members, it can quickly transfer heat to the frost-concentrated area, further accelerating the defrosting process.

[0016] In some embodiments, the heater passes through the support and the heat-conducting structure.

[0017] In this way, the reliability of the heater in contact with the support and heat-conducting structure is high.

[0018] In some embodiments, the thermally conductive structure includes:

[0019] The first heat-conducting part has an extension plane that is parallel to the extension plane of the support member, and the extension plane of the first heat-conducting part has an angle with the first direction.

[0020] The extension plane of the first heat-conducting part is parallel to the extension plane of the support member, which facilitates the passage of the refrigeration pipes through the support member and the heat-conducting structure, and also facilitates the passage of the heater through the support member and the heat-conducting structure. This makes installation more convenient.

[0021] In some embodiments, the first heat-conducting part is provided with a plurality of first mounting ports, and the support member is provided with a plurality of second mounting ports. The first mounting ports and the second mounting ports are provided in a one-to-one correspondence, and the refrigeration pipe passes through the first mounting ports and the second mounting ports.

[0022] In this way, the installation reliability of the refrigeration piping and supporting components is relatively high, as is the installation reliability of the refrigeration piping and heat-conducting structure.

[0023] In some embodiments, the first heat-conducting part is provided with at least one third mounting port, and the support member is provided with at least one fourth mounting port. The third mounting port and the fourth mounting port are provided in a one-to-one correspondence, and the heater passes through the third mounting port and the fourth mounting port.

[0024] In this way, the installation reliability of the heater and the support is relatively high, and the installation reliability of the heater and the heat-conducting structure is also relatively high.

[0025] In some embodiments, a first opening is provided at the bottom of the first heat-conducting part, the first opening is in communication with the outside of the first heat-conducting part, and the first opening is in communication with the third mounting port.

[0026] The bottom of the support is provided with a second opening, which communicates with the outside of the first heat-conducting part and with the fourth mounting port.

[0027] This makes it easy for the heater to be installed in the third mounting port through the first opening, and easy for the heater to be installed in the fourth mounting port through the second opening, thus making installation more convenient.

[0028] In some embodiments, the thermally conductive structure further includes:

[0029] The second heat-conducting part is connected to the first heat-conducting part. The extension plane of the second heat-conducting part and the extension plane of the first heat-conducting part have an angle. The second heat-conducting part abuts against the fin.

[0030] In this way, by setting a second heat-conducting part, the contact area between the heat-conducting structure and the fins is increased. The heat transferred from the heater to the first heat-conducting part is transferred to the fins through the refrigeration pipes, or it can be directly transferred to the fins through the second heat-conducting part, thereby achieving faster heat conduction and defrosting.

[0031] In some embodiments, the thermally conductive structure further includes:

[0032] The third heat-conducting part is connected to the first heat-conducting part and is located on the side of the first heat-conducting part away from the second heat-conducting part.

[0033] The extended plane of the third heat-conducting part forms an angle with the extended plane of the first heat-conducting part, and the third heat-conducting part abuts against the fin.

[0034] In this way, by setting a third heat-conducting part, which is located on opposite sides of the refrigeration pipeline, heat can be transferred to the refrigeration pipeline and fins from two directions, accelerating the heat transfer of the heater to various parts of the evaporator, reducing defrosting time, and improving defrosting efficiency.

[0035] In some embodiments, the extension plane of the second heat-conducting part is parallel to the extension plane of the evaporator;

[0036] The extended plane of the third heat-conducting section is parallel to the extended plane of the evaporator.

[0037] In this way, the contact area between the second heat-conducting part and the fins is relatively large, resulting in higher heat transfer efficiency. Similarly, the contact area between the third heat-conducting part and the fins is relatively large, leading to higher heat transfer efficiency.

[0038] In some embodiments, the number of heat-conducting structures is at least two, and the at least two heat-conducting structures are spaced apart along a first direction.

[0039] This results in a greater number of heat-conducting structures, more heat transfer paths, improved heat transfer efficiency, reduced defrosting time, and enhanced defrosting efficiency. Attached Figure Description

[0066] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0067] Figure 1 This is a structural diagram of a refrigerator in related technologies. Figure 2 for Figure 1 Explosion diagram, Figure 3 This is a schematic diagram of the structure of the inner liner, fan, and evaporator in a refrigerator according to related technologies. Figure 4 This is a schematic diagram of the structure of the evaporator and heater in the related technology.

[0068] Figure 5 This is a structural schematic diagram of the evaporator and heater in the related technology from another angle.

[0069] See Figures 1 to 5 As shown, in related technologies, frost-free refrigerators are also known as air-cooled refrigerators. An air-cooled refrigerator includes a cabinet 100, which includes an inner liner 110. The inner liner 110 has an inner cavity, and an air duct cover 200 is disposed within the inner cavity to divide the inner cavity into a cold source chamber and a cooling chamber. The cold source chamber contains an evaporator 400, a heater 600, and a fan 500. Under the action of the fan, air circulation is formed between the cold source chamber and the cooling chamber. The evaporator 400 has a relatively low temperature. Air enters from the bottom of the cold source chamber, exchanges cold air with the evaporator 400, and the generated cold air is blown into the cooling chamber by the fan 500, thus maintaining the temperature in the cooling chamber within a relatively low range. In this system, the evaporator 400 generates cooling capacity. After a period of cooling, frost, formed by the condensation of moisture from the air, will form on the evaporator 400. At this point, a heater 600 (installed at the bottom of the evaporator 400) is needed to conduct heat from the bottom to the evaporator 400, melting the frost into water, which then flows out of the refrigerator through the drain pipe. However, the contact area between the heater and the evaporator is small, resulting in fewer heat transfer paths and lower heat transfer efficiency. Therefore, the defrosting time for the evaporator is relatively long, and the efficiency is low.

[0070] To overcome the deficiencies in related technologies, the refrigerator provided in this application includes a cabinet, an evaporator, and a heater. The cabinet has an inner cavity, where the evaporator and heater are located. The evaporator includes at least two support members, a heat-conducting structure, refrigeration pipes, and fins. The at least two support members are spaced apart along a first direction. Along this first direction, the heat-conducting structure is located between the two support members. The refrigeration pipes pass through the support members and the heat-conducting structure, and the fins are disposed within the refrigeration pipes. The heater is in contact with both the support members and the heat-conducting structure. In this way, the heat from the heater can be transferred to the refrigeration pipes and fins through the support members and the heat-conducting structure. Compared to the heater's heat transfer only through the support members, this increases the heat transfer path, improves heat transfer efficiency, reduces defrosting time, and enhances defrosting efficiency. Furthermore, when the evaporator is operating, frost buildup is more severe in the central area of ​​the evaporator. With the heat-conducting structure located between the two support members, it can quickly transfer heat to the frost-concentrated area, further accelerating the defrosting process.

[0071] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0072] Figure 6 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application.

[0073] This application provides a refrigerator. The refrigerator can be a direct-cooling refrigerator or a frost-free refrigerator; the following description uses a frost-free refrigerator as an example.

[0074] See Figure 6 As shown, in some embodiments, the refrigerator includes a cabinet 100.

[0075] The housing 100 has an inner cavity.

[0076] In some embodiments, housing 100 includes an outer shell.

[0077] The outer casing has a first receiving cavity with a first pick-up and drop-out port and a second pick-up and drop-out port, which are respectively located on opposite sides of the outer casing in the depth direction (direction shown by the Y-axis) of the housing 100. The first pick-up and drop-out port may be located on the front side of the outer casing, and the second pick-up and drop-out port may be located on the rear side of the outer casing.

[0078] In some embodiments, the housing 100 includes a compressor compartment. The compressor compartment is located within the housing, and its opening is opposite to the second loading / unloading port, through which compressors and condensers, etc., can be placed into the compressor compartment.

[0079] In some embodiments, the housing 100 includes an inner liner 110.

[0080] The inner liner 110 is located inside the outer shell. The inner liner 110 forms at least one refrigeration compartment. The inner liner 110 has a third access port, which is opposite to the first access port. Items can be placed into the refrigeration compartment through the third access port and the first access port.

[0081] A foam layer is filled between the inner liner 110, the outer shell, and the compressor chamber. The foam layer is used to insulate the refrigeration chamber, thereby ensuring the refrigeration effect inside the refrigeration chamber.

[0082] In some embodiments, the refrigerator further includes an air duct cover 200, and the inner liner 110 is provided with an inner cavity. The air duct cover 200 is located in the inner cavity to divide the inner cavity into a cooling compartment and a cold source compartment along the depth direction. The depth direction is the direction shown by the Y-axis.

[0083] The cold source chamber and the refrigeration chamber are interconnected. When the fan 500 is working, the air in the cold source chamber and the cold source chamber circulates. The refrigeration chamber can be any of the following: a refrigerator chamber, a freezer chamber, or a variable temperature chamber.

[0084] See Figure 6 As shown, in some embodiments, the refrigerator includes a door 300.

[0085] The door 300 is movably connected to the box 100. The door 300 is openable and closable on the front side of the box 100 to close and open the cold source chamber, and to take out and put in items in the cold source chamber.

[0086] Figure 7 This is a schematic diagram of the refrigeration system in a refrigerator provided in an embodiment of this application.

[0087] See Figure 7 As shown, in some embodiments, the refrigerator includes a refrigeration system.

[0088] The refrigeration system may include a compressor 700, a condenser 800, a throttling device 900, and an evaporator 400. The compressor 700, condenser 800, throttling device 900, and evaporator 400 are connected in series via piping, through which refrigerant flows. The compressor 700 and condenser 800 may be located in the compressor compartment, while the evaporator 400 may be located in the cold source chamber.

[0089] When compressor 700 is operating, low-temperature, low-pressure refrigerant is drawn into compressor 700 and compressed into high-temperature, high-pressure superheated gas within the compressor cylinder before being discharged into condenser 800. The high-temperature, high-pressure refrigerant gas dissipates heat through condenser 800, its temperature continuously decreasing until it is gradually cooled into room-temperature, high-pressure saturated vapor, and further cooled into saturated liquid. The pressure of the refrigerant remains almost constant throughout the condensation process. The throttling device 900 may include a pressure-reducing pipe or an electronic expansion valve. This application describes the throttling device as including a pressure-reducing pipe, as pressure-reducing pipes are low-cost and less prone to malfunction. The condensed saturated liquid refrigerant undergoes throttling and pressure reduction through the pressure-reducing pipe, transforming the refrigerant into room-temperature, low-pressure wet vapor. Subsequently, the room-temperature, low-pressure wet vapor absorbs heat and vaporizes through evaporator 400, not only lowering the temperature of evaporator 400 and its surroundings but also transforming the refrigerant into a low-temperature, low-pressure gas. The evaporator 400 cools the air inside the cold source chamber, lowering its temperature. Driven by a fan, the cold air from the cold source chamber flows through the duct cover 200 into the cooling room, further lowering its temperature. The refrigerant exiting the evaporator 400 returns to the compressor 700, repeating the process to ensure the evaporator 400 continuously cools the air inside the cold source chamber, thus maintaining the cooling room at the set temperature.

[0090] Figure 8 This is a schematic diagram of the structure of the inner liner, fan, evaporator, and heater in a refrigerator provided in an embodiment of this application. Figure 9 This is a schematic diagram of the structure of the fan in the refrigerator provided in an embodiment of this application.

[0091] See Figure 8 and Figure 9As shown, in some embodiments, the refrigerator includes a fan 500.

[0092] Among them, fan 500 is located in the cold source chamber.

[0093] The fan 500 is equipped with an air inlet structure 510, which is connected to the cold source chamber. When the fan 500 is running, the air in the cold source chamber enters the fan 500 through the air inlet structure 510, and is then discharged into the refrigeration room by the fan 500.

[0094] Specifically, the air intake structure 510 can be circular.

[0095] The evaporator 400 is located in the cold source chamber and is located on one side of the fan 500.

[0096] Specifically, see Figure 8 As shown, the evaporator 400 is located in the cold source chamber and below the fan 500. Under the action of the fan 500, air flows from the bottom of the evaporator 400 toward the air inlet structure 510.

[0097] Figure 10 This is a schematic diagram of the structure of the evaporator and heater in the refrigerator provided in an embodiment of this application. Figure 11 for Figure 10 Exploded view.

[0098] See Figure 10 and Figure 11 As shown, in some embodiments, the refrigerator includes a heater 600. The heat generated by the heater 600 during operation is transferred to the evaporator 400, thereby melting the frost on the evaporator 400.

[0099] The heater 600 is located in the inner cavity, specifically in the cold source chamber.

[0100] Specifically, the heater 600 is located on one side of the evaporator 400. The heater 600 is in contact with the evaporator 400, so that heat can be directly transferred to the evaporator 400.

[0101] Specifically, the heater 600 can be located on the side of the evaporator 400 away from the fan 500.

[0102] Specifically, the heater 600 is located at the bottom of the evaporator 400.

[0103] See Figure 10 and Figure 11 As shown, in some embodiments, the evaporator 400 includes a body 410.

[0104] In some embodiments, the body 410 includes a refrigeration line 411. The refrigeration line 411 is used to supply refrigerant flow.

[0105] In some embodiments, the refrigeration piping 411 is arranged in a serpentine pattern.

[0106] In some embodiments, the body 410 includes a support 412. The support 412 is used to support the cooling pipes 411.

[0107] The refrigeration pipe 411 is inserted into the support 412.

[0108] The number of support members 412 is at least two, and the at least two support members 412 are spaced apart along the first direction.

[0109] Specifically, there are two support members 412.

[0110] In some embodiments, the number of support members 412 may be three or four, etc.

[0111] It should be noted that the first direction is the width direction of the box 100, which is the direction shown by the X-axis in the figure.

[0112] In some embodiments, the body 410 includes a thermostat disposed on the refrigeration pipe 411.

[0113] See Figure 10 and Figure 11 As shown, in some embodiments, the evaporator 400 includes a plurality of fins 420.

[0114] The fins 420 are disposed on the outer wall of the body 410.

[0115] Specifically, fins 420 are disposed on the outer wall of the refrigeration pipe 411.

[0116] See Figure 10 and Figure 11 As shown, in some embodiments, the evaporator 400 includes a heat-conducting structure 430.

[0117] In the first direction, the heat-conducting structure 430 is located between the two support members 412.

[0118] The heater is in contact with the support member 412 and the heat-conducting structure 430. In this way, the heat from the heater can be transferred to the refrigeration pipes and fins through the support member 412 and the heat-conducting structure 430. Compared with the heat from the heater being transferred only through the support member 412, the heat transfer path is increased, the heat transfer efficiency is improved, the defrosting time is reduced, and the defrosting efficiency is improved.

[0119] Moreover, when the evaporator is working, the frost in the middle area of ​​the evaporator is more severe. The heat conduction structure 430 is located between the two support members 412. The heat conduction structure 430 can quickly transfer heat to the frost concentration area and can also speed up the defrosting process.

[0120] In some embodiments, the heater 600 passes through the support member 412. The heat generated by the heater 600 can be transferred through the support member 412 to the cooling pipe 411, and then through the cooling pipe 411 to the fins 420. Moreover, the contact reliability is high.

[0121] In some embodiments, the heater passes through the heat-conducting structure 430. The heat generated by the heater 600 can be transferred through the heat-conducting structure 430 to the cooling pipe 411, and then through the cooling pipe 411 to the fins 420. Moreover, the reliability of the contact is high.

[0122] Figure 12 This is a schematic diagram of the heat-conducting structure in a refrigerator provided in an embodiment of this application.

[0123] See Figure 12 As shown, in some embodiments, the thermally conductive structure 430 includes a first thermally conductive portion 431.

[0124] The extension plane of the first heat-conducting part 431 is parallel to the extension plane of the support member 412, and the extension plane of the first heat-conducting part 431 has an angle with the first direction.

[0125] Understandably, the extension plane of the first heat-conducting part 431 is parallel to the extension plane of the support member 412, which facilitates the passage of the refrigeration pipe 411 through the support member 412 and the heat-conducting structure 430, and also facilitates the passage of the heater 600 through the support member 412 and the heat-conducting structure 430. This makes installation more convenient.

[0126] It should be noted that the extension plane of the first heat-conducting part 431 and the extension plane of the support member 412 are planes formed by the Z-axis and Y-axis. The first direction is the direction shown by the X-axis.

[0127] The first heat-conducting part 431 can be in the shape of a flat plate.

[0128] See Figure 12 As shown, in some embodiments, the first heat-conducting part 431 is provided with a plurality of first mounting ports 4311, and the support member 412 is provided with a plurality of second mounting ports. The first mounting ports 4311 and the second mounting ports are provided in a one-to-one correspondence, and the refrigeration pipe 411 passes through the first mounting ports 4311 and the second mounting ports.

[0129] In this way, the installation reliability of the refrigeration pipe 411 and the support 412 is relatively high, and the installation reliability of the refrigeration pipe 411 and the heat-conducting structure 430 is also relatively high.

[0130] In some embodiments, the first heat-conducting part 431 is provided with at least one third mounting port 4312, and the support member 412 is provided with at least one fourth mounting port. The third mounting port 4312 and the fourth mounting port are provided in a one-to-one correspondence, and the heater 600 passes through the third mounting port 4312 and the fourth mounting port.

[0131] In this way, the installation reliability of heater 600 and support member 412 is relatively high, and the installation reliability of heater 600 and heat-conducting structure 430 is also relatively high.

[0132] For example, the number of the third mounting port 4312 and the fourth mounting port can be one, two, or three, etc.

[0133] In some embodiments, the bottom of the first heat-conducting part 431 is provided with a first opening, which communicates with the outside of the first heat-conducting part 431 and with the third mounting port 4312. This facilitates the installation of the heater 600 through the first opening into the third mounting port 4312, thus improving installation convenience.

[0134] In some embodiments, the bottom of the support member 412 is provided with a second opening, which communicates with the outside of the first heat-conducting part 431 and with a fourth mounting port. This facilitates the installation of the heater 600 through the second opening into the fourth mounting port, thus improving installation convenience.

[0135] It should be noted that in some embodiments, the heat-conducting structure 430 and the support member 412 have the same structure. This helps to reduce the difficulty of processing, and during the installation process, there is no need to distinguish between the heat-conducting structure 430 and the support member 412, resulting in higher installation efficiency.

[0136] Figure 13 This is a schematic diagram of another structure of the evaporator and heater in a refrigerator provided in an embodiment of this application. Figure 14 for Figure 13 Explosion diagram, Figure 15 This is another schematic diagram of the heat-conducting structure in a refrigerator provided in an embodiment of this application.

[0137] See Figures 13 to 15 As shown, in some embodiments, the heat-conducting structure 430 further includes a second heat-conducting part 432.

[0138] The second heat-conducting part 432 is connected to the first heat-conducting part 431. The extension plane of the second heat-conducting part 432 and the extension plane of the first heat-conducting part 431 have an angle. The second heat-conducting part 432 abuts against the fin.

[0139] Understandably, by setting the second heat-conducting part 432, the contact area between the heat-conducting structure 430 and the fins is increased. The heat transferred from the heater 600 to the first heat-conducting part 431 is transferred to the fins through the cooling pipe 411, or it can be directly transferred to the fins through the second heat-conducting part 432, thereby achieving faster heat conduction and defrosting.

[0140] In some embodiments, the thermally conductive structure 430 further includes a third thermally conductive portion 433.

[0141] The third heat-conducting part 433 is connected to the first heat-conducting part 431, and the third heat-conducting part 433 is located on the side of the first heat-conducting part 431 away from the second heat-conducting part 432.

[0142] The extended plane of the third heat-conducting part 433 forms an angle with the extended plane of the first heat-conducting part 431, and the third heat-conducting part 433 abuts against the fin.

[0143] It is understandable that by setting the third heat-conducting part 433, which is located on opposite sides of the first heat-conducting part 431, heat can be transferred to the refrigeration pipe 411 and the fins from two directions, thereby accelerating the heat transfer of the heater 600 to various parts of the evaporator, reducing defrosting time, and improving defrosting efficiency.

[0144] In some embodiments, the extending plane of the second heat-conducting portion 432 is parallel to the extending plane of the evaporator. This results in a larger contact area between the second heat-conducting portion 432 and the fins, leading to higher heat transfer efficiency.

[0145] The extension plane of the second heat-conducting part 432 and the extension plane of the evaporator are the planes formed by the Z-axis and X-axis as shown in the figure.

[0146] In some embodiments, the extension plane of the third heat-conducting part 433 is parallel to the extension plane of the evaporator.

[0147] In this way, the contact area between the third heat-conducting part 433 and the fins is relatively large, resulting in higher heat transfer efficiency.

[0148] The extension plane of the third heat-conducting part 433 and the extension plane of the evaporator are the planes formed by the Z-axis and X-axis as shown in the figure.

[0149] See Figure 10 and Figure 13 As shown, in some embodiments, the number of heat-conducting structures 430 is at least two, and the at least two heat-conducting structures 430 are spaced apart along the first direction. This increases the number of heat-conducting structures 430, increases the heat transfer paths, improves heat transfer efficiency, reduces defrosting time, and enhances defrosting efficiency.

[0150] Specifically, there are two thermally conductive structures 430.

[0151] In some embodiments, the number of thermally conductive structures 430 may be three or four, etc.

[0152] In some embodiments, the thermally conductive structure 430 is a metallic structure. Metals have good thermal conductivity.

[0153] In some embodiments, the thermally conductive structure 430 is an aluminum structure. It is understood that aluminum has good thermal conductivity, which facilitates rapid heat transfer.

[0154] In some embodiments, the thermally conductive structure 430 is a copper structure.

[0155] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0156] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0157] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0158] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0159] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0160] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0161] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0162] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0163] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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; 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.

[0164] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
