Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, and mainly relates to a refrigeration device. Background Art

[0002] A refrigerator is a device that maintains a constant low temperature to store items, and it is widely used in contemporary life or industrial production.

[0003] A press cabin is provided at the bottom of the refrigerator. A press cabin bottom plate is provided in the press cabin. Components such as a compressor, a fan, a condenser, and a water-saving tray required by the refrigerator are arranged on the press cabin bottom plate.

[0004] Currently, the capacitor is mainly exposed in the press cabin. When there is no rear cover provided in the press cabin of the refrigerator or the user opens the rear cover, the user may come into direct contact with the capacitor by hand. In this case, the existing structure is difficult to meet the requirements of forced insulation. Moreover, due to the vibration generated during the operation of the press, the capacitor is likely to shake, affecting its use safety and working stability. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a refrigeration device to improve the safety and stability of the capacitor arranged in the press cabin during daily use.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] One aspect of the present application provides a refrigeration device, including a box body, which forms the outer shell of the refrigeration device; a compressor chamber is arranged inside the box body; a capacitor assembly is arranged in the compressor chamber, and the capacitor assembly includes a mounting shell, a compressor capacitor, and a fixing member; wherein, the mounting shell is provided with a mounting cavity; the compressor capacitor is installed in the mounting cavity, and one axial end of the compressor capacitor is used for electrically connecting with the compressor; one end of the fixing member penetrates through the mounting cavity, and the other axial end of the compressor capacitor is connected with one end of the fixing member to axially fix the compressor capacitor in the mounting cavity; the other end of the fixing member protrudes outside the mounting shell, and the end of the fixing member protruding outside the mounting shell is detachably connected to the inner wall of the compressor chamber to fix the capacitor assembly in the compressor chamber.

[0008] The present application discloses a refrigeration device. By installing the compressor capacitor inside the installation shell, the installation shell provides a closed and protective installation environment for the capacitor, effectively preventing users from directly contacting the compressor capacitor. One end of the fixing member is connected to the other axial end of the compressor capacitor, and the other end of the fixing member protrudes outside the installation shell, thereby fixing the entire capacitor assembly inside the compressor chamber to limit the axial direction of the compressor capacitor and prevent the compressor capacitor from axially moving during the operation of the compressor. In this way, the compressor capacitor can be stably installed inside the installation shell, avoiding the shaking of the compressor capacitor inside the installation shell due to the vibration transmitted by the compressor, and improving the safety and stability of the compressor capacitor when used inside the compressor chamber.

[0009] In some embodiments of the present application, a spaced space is formed between the axial end of the compressor capacitor away from the fixing member and the installation shell; an electrical connection wire is provided at the axial end of the compressor capacitor away from the fixing member, and the electrical connection wire passes through the spaced space and extends outside the installation shell. By reserving a spaced space between the compressor capacitor and the installation shell, when the compressor capacitor encounters abnormal conditions such as a steep increase in voltage, due to reasons such as an increase in internal pressure or expansion of internal materials in the compressor capacitor, the axial length of the compressor capacitor increases, and its internal fuse may melt due to overheating, thereby cutting off the circuit. Among them, the spaced space can ensure that the compressor capacitor has sufficient expansion space. The installation shell designed in the present application neither hinders the explosion-proof structure of the compressor capacitor nor can effectively fix the compressor capacitor, improving the safety of the compressor capacitor.

[0010] In some embodiments of the present application, a first end wall is formed at the axial end of the compressor capacitor away from the fixing member, the installation shell is provided with a second end wall, the first end wall and the second end wall are axially opposite to each other, and the value range of the straight-line distance between the first end wall and the second end wall is 8 mm to 12 mm. The spaced space is within this value range, which neither hinders the explosion-proof structure of the compressor capacitor nor causes the overall volume of the capacitor assembly to be too large to occupy the internal installation space of the compressor chamber.

[0011] In some embodiments of the present application, it further includes a first limiting portion, the first limiting portion is arranged inside the installation shell, and the first limiting portion axially abuts against the axial end of the compressor capacitor close to the fixing member to prevent the compressor capacitor from axially moving towards the end close to the fixing member. In order to more effectively axially fix the compressor capacitor inside the compressor chamber, by arranging the first limiting portion inside the installation shell and the first limiting portion abuts against the axial end of the compressor capacitor close to the fixing member, that is, the bottom of the compressor capacitor abuts against the upper end surface of the first limiting portion, thereby effectively restricting the axial movement of the compressor capacitor towards the fixing member end, so that the axial position of the compressor capacitor inside the installation shell can be fixed, which helps to prevent position deviation caused by vibration or impact.

[0012] In some embodiments of the present application, a second limiting portion is further included. The second limiting portion is disposed within the mounting shell and on a side of the first limiting portion away from the piezoelectric capacitor. The fixing member is provided with a first rib, and the first rib axially abuts against the second limiting portion to prevent the fixing member from axially moving toward an end close to the piezoelectric capacitor. By disposing the second limiting portion within the mounting shell, the second limiting portion can serve as an axial blocking point and abut against the first rib on the fixing member. Among them, the lower end surface of the second limiting portion axially abuts against the upper end surface of the first rib, thereby restricting the axial movement of the fixing member toward an end close to the piezoelectric capacitor, helping to reduce the risk of loosening or displacement caused by vibration, impact or external force, and ensuring the reliability and durability of the capacitor assembly during operation.

[0013] In some embodiments of the present application, the first limiting portion is provided with a limiting hole, and the fixing member is provided with a second rib. The second rib is located on a side of the fixing member close to the piezoelectric capacitor, and the second rib is snapped into the limiting hole to restrict the circumferential rotation of the fixing member. By providing the second rib on the fixing member, the second rib is located on a side of the fixing member close to the piezoelectric capacitor, and the shape and size of the second rib are designed to be able to tightly snap into the limiting hole on the first limiting portion. In this way, the snap-fit structure formed by the second rib and the limiting hole can effectively restrict the circumferential rotation of the fixing member (i.e., the direction around its axis), thereby ensuring the stability and reliability of the fixing member after installation.

[0014] In some embodiments of the present application, a limiting rib is further included. The limiting rib is disposed within the mounting shell, the limiting rib is circumferentially disposed along the inner peripheral wall of the mounting shell, and the limiting rib is provided with a through hole. The piezoelectric capacitor passes through the through hole to perform circumferential limitation on the piezoelectric capacitor. In this way, when the piezoelectric capacitor passes through the through hole of the limiting rib, the circumferential movement of other parts of the piezoelectric capacitor in the axial direction can be effectively restricted, which is beneficial to improving the relative position stability between the piezoelectric capacitor and other components within the mounting shell.

[0015] In some embodiments of the present application, a snap-fit portion is provided at an end of the fixing member away from the piezoelectric capacitor, and the snap-fit portion is detachably connected to the inner wall of the compressor chamber. By providing the snap-fit portion, the fixing member can be quickly connected to the inner wall of the compressor chamber without using additional fasteners (such as screws, nuts, etc.), which not only simplifies the installation process but also reduces the installation cost.

[0016] In some embodiments of the present application, a connection hole is provided at one end of the fixing member close to the piezoelectric capacitor. The connection hole is arranged towards the side where the piezoelectric capacitor is located. A connection post protrudes from the end wall of the piezoelectric capacitor facing the fixing member, and the connection post is inserted into the connection hole to fix the piezoelectric capacitor on the fixing member. When connecting the piezoelectric capacitor to the fixing member by inserting the connection post into the connection hole, there is no need for complex fixing steps or additional fasteners, and the piezoelectric capacitor can be firmly fixed on the fixing member, which not only simplifies the installation process but also improves the installation efficiency.

[0017] In some embodiments of the present application, a press machine bin plate is provided in the compressor chamber. The press machine bin plate is arranged at the bottom of the compressor chamber, and the part of the other end of the fixing member protruding outside the installation shell is snap-connected to the press machine bin plate. The connection between the other end of the fixing member and the press machine bin plate through snap connection enables the fixing member to be stably fixed on the press machine bin plate, thereby providing stable support for the piezoelectric capacitor and the like, and contributing to the stability and reliability of the compressor during operation.

[0018] In some embodiments of the present application, the installation shell includes a first shell member and a second shell member. The first shell member and the second shell member are arranged opposite to each other, and an installation cavity is formed by enclosing between the first shell member and the second shell member; one side of the first shell member is rotatably connected to one side of the second shell member, so that the first shell member rotates relative to the second shell member to open or close the installation cavity. By arranging the first shell member and the second shell member to be rotatably connected, the operator can easily open the installation cavity by rotating the first shell member or the second shell member, which simplifies the process of repairing and maintaining the capacitor assembly.

[0019] In some embodiments of the present application, a flexible connection is adopted between the first shell member and the second shell member, so that the first shell member can rotate relative to the second shell member. By adopting a flexible connection, the relative movement between the first shell member and the second shell member can be realized only by using a connection material with a certain flexibility, which can greatly simplify the structure of the installation shell.

[0020] In some embodiments of the present application, the side of the first shell member far from the rotatable connection with the second shell member and the side of the second shell member far from the rotatable connection with the first shell member are detachably connected. The detachable connection between the first shell member and the second shell member enables the operator to more conveniently separate the first shell member and the second shell member, thereby directly opening the installation shell, which simplifies the process of repairing and replacing the capacitor assembly.

[0044] The refrigeration device in the embodiment of the present invention can be a refrigeration cabinet such as a freezer, a refrigerator, etc. Taking a refrigerator as an example, the technical solutions for improving the refrigeration device in the embodiment of the invention are described in detail below.

[0045] Figure 1 It is a front view of the refrigeration device according to an embodiment of the present application.

[0046] Please refer to Figure 1As shown in the figure, the refrigerator provided by the embodiment of the present utility model may include a cabinet 1. The cabinet 1 may adopt a hollow structure such as a cuboid. The cabinet 1 forms the outer shell of the refrigerator. It should be noted that the cabinet 1 may also adopt a hollow shell structure of other shapes.

[0047] In some embodiments, a refrigerating compartment (not shown in the figure) may be provided inside the cabinet 1. The refrigerating compartment may be provided as multiple refrigerating compartments.

[0048] In some embodiments, the multiple refrigerating compartments may serve as independent storage spaces, such as a freezer, a refrigerator compartment, and a variable-temperature compartment, etc., to meet different refrigeration requirements such as freezing, refrigerating, and variable-temperature according to different types of food, and to store items that need to be refrigerated or frozen. The multiple refrigerating compartments may be arranged in an up-and-down partition or a left-and-right partition.

[0049] In some embodiments, the refrigerator may include an inner liner. The refrigerating compartment may be formed within the inner liner.

[0050] Please refer to the attached Figure 1 , in some embodiments, the refrigerator may include a door. The door 11 may be hinged to the front side of the cabinet 1 for opening and closing the refrigerating compartment.

[0051] It should be noted that multiple doors 11 may be provided. The doors 11 may be arranged in one-to-one correspondence with the refrigerating compartments. Multiple doors 11 may open and close one refrigerating compartment simultaneously. One door 11 may also open and close multiple refrigerating compartments simultaneously.

[0052] In some embodiments, the refrigerator may include a refrigeration system. The refrigeration system may be disposed inside the cabinet 1. The refrigeration system may be used to provide cold air inside the refrigerator to maintain a low-temperature environment in each refrigerating compartment.

[0053] Figure 2 is a schematic rear view of a refrigeration device according to an embodiment of the present application; Figure 3 is Figure 2 a schematic rear view of a refrigeration device with some structures hidden.

[0054] As Figure 2 and Figure 3 shown, in some embodiments, the refrigeration system may include a compressor 12. The compressor 12, as the power source of the refrigeration cycle, may suck in a refrigerant gas at low temperature and low pressure and compress it into a gas at high temperature and high pressure. The compressor 12 may deliver the refrigerant at high temperature and high pressure to the condenser.

[0055] In some embodiments, the refrigeration system may include a condenser (not shown in the figure). The condenser can be used to receive the refrigerant flowing out of the compressor 12, and can cool and convert the high-temperature and high-pressure refrigerant gas from the compressor 12 into a liquid state. The condenser can transfer the heat in the refrigerant to the surrounding air, reducing the temperature of the refrigerant.

[0056] In some embodiments, the refrigeration system may include a throttling device (not shown in the figure). The condenser can deliver the condensed refrigerant into the throttling device. The throttling device can employ a capillary tube. The throttling device can be used to throttle down the pressure of the refrigerant.

[0057] In some embodiments, the refrigeration system may include an evaporator (not shown in the figure). The throttling device can deliver the refrigerant with reduced pressure after throttling into the evaporator. The evaporator can be used for the refrigerant vapor to evaporate and boil, so as to absorb the heat of the surrounding medium.

[0058] In some embodiments, the compressor 12, the condenser, the throttling device, and the evaporator can be connected in sequence to form a refrigeration circuit. The refrigerant can circulate within the refrigeration circuit to achieve refrigeration inside the cabinet 1.

[0059] As Figure 2 and Figure 3 shown, in some embodiments, a compressor chamber 101 may be provided inside the cabinet 1. The compressor 12 can be disposed within the compressor chamber 101. The compressor chamber 101 can be provided in the bottom area inside the cabinet 1. The compressor chamber 101 can be located at the rear lower side of the refrigerating compartment. The compressor 12, the condenser, the throttling device, etc. can be disposed within the refrigerating compartment.

[0060] It should be noted that in some other embodiments, the compressor chamber 101 can also be provided at other positions such as the top or side of the cabinet 1.

[0061] Figure 4 For Figure 3 the partial enlarged view at location A of Figure 5 For Figure 2 the schematic diagram of the capacitor assembly of Figure 6 For Figure 5 the open schematic diagram of the mounting shell of

[0062] Please refer to Appendix Figure 4 and Appendix Figure 5 , in some embodiments, the refrigerator may include a capacitor assembly 2. The capacitor assembly 2 can be disposed within the compressor chamber 101. By directly integrating the capacitor assembly 2 within the compressor chamber 101, the external wiring and connection points can be reduced, making the overall design of the refrigerator more concise and compact.

[0063] As Figure 6As shown, in some embodiments, the capacitor assembly 2 may include a piezoelectric capacitor 22. One axial end of the piezoelectric capacitor 22 may be used for electrical connection to the compressor 12.

[0064] As Figure 5 and Figure 6 As shown, in some embodiments, the capacitor assembly 2 may include a mounting shell 21. The mounting shell 21 may be provided with a mounting cavity 201, and the piezoelectric capacitor 22 may be installed in the mounting cavity 201. Since there is no rear cover provided in the compressor compartment of the refrigerator or when the user opens the rear cover, the user may come into direct contact with the capacitor by hand. In such a case, the existing structure is difficult to meet the requirements of forced insulation. By providing the mounting shell 21, a closed environment can be provided for the piezoelectric capacitor 22, avoiding direct contact between the operator and the capacitor and thus eliminating potential safety hazards. Moreover, the provision of the mounting shell 21 can provide additional structural support for the piezoelectric capacitor 22, facilitating the piezoelectric capacitor 22 to remain stable during the operation of the refrigerator and reducing the risk of damage caused by vibration or movement.

[0065] As Figure 6 As shown, in some embodiments, the mounting shell 21 may include a first shell member 211 and a second shell member 212. The first shell member 211 and the second shell member 212 are disposed opposite to each other, and the mounting cavity 201 is formed by enclosing between the first shell member 211 and the second shell member 212.

[0066] In some embodiments, the first shell member 211 and the second shell member 212 may be disposed opposite to each other face to face to enclose the mounting cavity 201.

[0067] As Figure 5 and Figure 6 As shown, in some embodiments, one side of the first shell member 211 and one side of the second shell member 212 may be rotatably connected so that the first shell member 211 rotates relative to the second shell member 212 to open or close the mounting cavity 201. In order to improve the stability of installing the piezoelectric capacitor 22 in the mounting shell 21, the first shell member 211 and the second shell member 212 are arranged to be rotatably connected. In this way, by rotating the first shell member 211 or the second shell member 212, the operator can easily open the mounting cavity 201, simplifying the process of repairing and maintaining the capacitor assembly 2.

[0068] In some embodiments, a flexible connection is adopted between the first shell member 211 and the second shell member 212 so that the first shell member 211 can rotate relative to the second shell member 212.

[0069] It should be noted that a flexible connection can refer to a connection method that can be bent, twisted, or stretched, which can provide a certain degree of flexibility and adaptability. Since a flexible connection does not require complex components such as hinges, sliding rails, or bearings, and only needs a connection material with a certain degree of flexibility to achieve the relative movement between the first housing member 211 and the second housing member 212, compared with a rigid connection, a flexible connection can simplify the structural design of the mounting housing 21.

[0070] In some embodiments, the first housing member 211 and the second housing member 212 can be integrally formed.

[0071] In some embodiments, the first housing member 211 and the second housing member 212 can be made of PVC material.

[0072] In some other embodiments, the first housing member 211 and the second housing member 212 can be rotatably connected by a hinge.

[0073] As Figure 5 and Figure 6 shown, in some embodiments, the side of the first housing member 211 away from the side rotatably connected to the second housing member 212 and the side of the second housing member 212 away from the side rotatably connected to the first housing member 211 are detachably connected. In this way, the detachable connection between the first housing member 211 and the second housing member 212 enables the operator to more conveniently separate the first housing member 211 and the second housing member 212, thereby directly opening the mounting housing 21, which simplifies the repair and replacement process of the capacitor assembly 2.

[0074] Figure 7 For Figure 6 the schematic diagram of the mounting housing.

[0075] In some embodiments, the first housing member 211 and the second housing member 212 can adopt a detachable connection method of snap connection.

[0076] Please refer to the attached Figure 7 , in some embodiments, a buckle 24 is provided on the side of the first housing member 211 away from the side rotatably connected to the second housing member 212, and a slot 202 is provided on the side of the second housing member 212 away from the side rotatably connected to the first housing member 211. When the first housing member 211 is closed on the second housing member 212, the buckle 24 can be snapped into the slot 202. Through the design of the buckle 24 and the slot 202, the operator can quickly close the first housing member 211 onto the second housing member 212 and achieve fixation through a simple snapping action. Similarly, when separating, only need to gently press the buckle 24 or apply a certain force to separate the two, without using additional tools. When the buckle 24 is correctly snapped into the slot 202, the connection between the first housing member 211 and the second housing member 212 is stable.

[0077] In some embodiments, a detachable structure using nuts or bolts may be employed between the first housing member 211 and the second housing member 212.

[0078] Please refer to the attached Figure 7 , in some embodiments, a first fixing portion 4 is provided on a side of the first housing member 211 remote from the side rotatably connected to the second housing member 212, and a second fixing portion 5 is provided on a side of the second housing member 212 remote from the side rotatably connected to the first housing member 211. The first fixing portion 4 is provided with a second through hole 401, and the second fixing portion 5 is provided with a connection groove 501. The through hole is for one end of a connecting member to pass through, and one end of the connecting member passes through the through hole and extends into the connection groove 501. The connecting member is used to connect the first fixing portion 4 and the second fixing portion 5 so that the first housing member 211 and the second housing member 212 are fixed together. By tightly connecting the first fixing portion 4 and the second fixing portion 5 with connecting members such as screws and bolts, a connection structure with high strength and high stability can be formed.

[0079] In some embodiments, the detachable connection structure between the first housing member 211 and the second housing member 212 employs the cooperation of the above-mentioned snap 24 and slot 202, as well as the bolt connection structure of the first fixing portion 4 and the second fixing portion 5.

[0080] In some other embodiments, the detachable structure between the first housing member 211 and the second housing member 212 may adopt a magnetic attraction structure.

[0081] Figure 8 For Figure 5 is a schematic cross-sectional view; Figure 9 For Figure 6 is a partial enlarged view at B of Figure 10 is a three-dimensional schematic view of the fixing member; Figure 11 For Figure 10 is a three-dimensional schematic view from another perspective of

[0082] As Figure 6 and Figure 8 shown, in some embodiments, the capacitor assembly 2 may include a fixing member 23. The fixing member 23 can be used to fix the capacitor assembly 2 in the compressor chamber 101 to prevent loosening or falling off due to vibration or external force.

[0083] As Figure 8As shown, in some embodiments, one end of the fixing member 23 can pass through the installation cavity 201. The other axial end of the piezoelectric capacitor 22 is connected to one end of the fixing member 23 to axially fix the piezoelectric capacitor 22 within the installation cavity 201. Since the compressor chamber 101 is provided with a compressor 12, the compressor 12 will generate a certain degree of vibration during operation. To prevent the piezoelectric capacitor 22 from undergoing axial displacement within the installation shell 21, by passing one end of the fixing member 23 through the installation cavity 201 and connecting it to the other axial end of the piezoelectric capacitor 22, the piezoelectric capacitor 22 can be initially axially fixed, effectively preventing the piezoelectric capacitor 22 from moving axially, thereby improving the stability and reliability of the capacitor.

[0084] As Figure 8 shown, in some embodiments, the other end of the fixing member 23 can protrude outside the installation shell 21. The end of the fixing member 23 that protrudes outside the installation shell 21 is detachably connected to the inner wall of the compressor chamber 101 to fix the capacitor assembly 2 within the compressor chamber 101. By protruding one end of the fixing member 23 outside the installation shell 21 and detachably connecting it to the inner wall of the compressor chamber 101, the entire capacitor assembly 2 can be fixed within the compressor chamber 101. Moreover, the detachable connection structure enables the capacitor assembly 2 to be conveniently installed into or removed from the compressor chamber 101.

[0085] In some embodiments, the detachable connection structure can be a threaded connection, a snap 24 connection, a pin connection, etc.

[0086] As Figure 8 and Figure 9 shown, in some embodiments, a clamping portion 233 can be provided at one end of the fixing member 23 away from the piezoelectric capacitor 22. The clamping portion 233 is detachably connected to the inner wall of the compressor chamber 101. Among them, by providing the clamping portion 233, the fixing member 23 can be quickly connected to the inner wall of the compressor chamber 101 without using additional fasteners (such as screws, nuts, etc.), which not only simplifies the installation process but also reduces the installation cost.

[0087] As Figure 4 shown, in some embodiments, a press machine bin plate 6 can be provided within the compressor chamber 101, and the press machine bin plate 6 can be disposed at the bottom of the compressor chamber 101. In this way, by providing the press machine bin plate 6, which is located at the bottom of the compressor chamber 101, it can be used to support and fix the compressor 12 assembly.

[0088] As Figure 4As shown, in some embodiments, the other end of the fixing member 23 may protrude from a portion outside the mounting shell 21 and be snap-connected to the press machine bin plate 6. Among them, the other end of the fixing member 23 and the press machine bin plate 6 are snap-connected, so that the fixing member 23 can be stably fixed on the press machine bin plate 6, thereby providing stable support for the compressor capacitor 22, etc., and contributing to the stability and reliability of the compressor 12 during operation.

[0089] As Figure 10 and Figure 11 As shown, in some embodiments, the snap connection portion 233 may include a hook, and a limiting groove 203 is formed between the hook and the fixing member 23. The press machine bin plate 6 is inserted into the limiting groove 203, so that the fixing member 23 can be connected to the press machine bin plate 6.

[0090] As Figure 10 and Figure 11 As shown, in some embodiments, the fixing member 23 may adopt an I-shaped snap structure.

[0091] As Figure 8 As shown, in some embodiments, one end in the axial direction of the compressor capacitor 22 may refer to the upper end of the compressor capacitor 22, and one end in the axial direction of the compressor capacitor 22 may refer to the lower end of the compressor capacitor 22. In this way, the upper end of the compressor capacitor 22 can be electrically connected to the compressor 12 through the electrical connection wire 3, and one end in the axial direction of the compressor capacitor 22 can be connected to the fixing member 23. Furthermore, the whole compressor capacitor 22 can be axially fixed in the compressor chamber 101 through the fixing member 23.

[0092] It should be noted that by installing the compressor capacitor 22 in the mounting shell 21, the mounting shell 21 provides a closed and protective installation environment for the capacitor, effectively preventing users from directly contacting the compressor capacitor 22; one end of the fixing member 23 is connected to the other end in the axial direction of the compressor capacitor 22, and the other end of the fixing member 23 protrudes outside the mounting shell 21, and then the whole capacitor assembly 2 is fixed in the compressor chamber 101 to limit the axial direction of the compressor capacitor 22 and prevent the compressor capacitor 22 from axially moving during the operation of the compressor 12. In this way, the compressor capacitor 22 can be stably installed in the mounting shell 21, avoiding the compressor capacitor 22 from shaking in the mounting shell 21 due to the vibration transmitted by the press machine, and improving the safety and stability of the compressor capacitor 22 when used in the compressor chamber 101.

[0093] As Figure 7 and Figure 9As shown, in some embodiments, the capacitor assembly 2 may include a first limiting portion 25. The first limiting portion 25 may be disposed within the mounting housing 21. The first limiting portion 25 axially abuts against an axially proximal end of the piezoelectric capacitor 22 near the fixing member 23 to prevent the piezoelectric capacitor 22 from axially moving towards the end near the fixing member 23. In order to more effectively axially fix the piezoelectric capacitor 22 within the compressor chamber 101, by providing the first limiting portion 25 within the mounting housing 21 and the first limiting portion 25 abutting against an axially proximal end of the piezoelectric capacitor 22 near the fixing member 23, that is, the bottom of the piezoelectric capacitor 22 abuts against the upper end surface of the first limiting portion 25, thereby effectively restricting the axial movement of the piezoelectric capacitor 22 towards the fixing member 23, enabling the axial position of the piezoelectric capacitor 22 within the mounting housing 21 to be fixed, which helps prevent position offset caused by vibration or impact.

[0094] It should be noted that in addition to the axial fixation provided by the fixing member 23 for the piezoelectric component, the first limiting portion 25 provides additional support for the piezoelectric capacitor 22. In this way, the fixing member 23 and the first limiting portion 25 can form a dual fixation structure for the piezoelectric capacitor 22, making the position of the piezoelectric capacitor 22 within the mounting housing 21 more stable and reducing position changes caused by external environmental factors (such as temperature changes, mechanical vibrations, etc.).

[0095] As Figure 6 and Figure 7 As shown, in some embodiments, the first limiting portion 25 may be provided with a limiting hole 204. The fixing member 23 may be provided with a second rib 232. The second rib 232 may be located on a side of the fixing member 23 near the piezoelectric capacitor 22, and the second rib 232 is snapped into the limiting hole 204 to restrict the fixing member 23 from rotating circumferentially.

[0096] During the operation of the compressor 12 within the compressor chamber 101, vibrations will occur, but there may still be circumferential displacements. By providing the second rib 232 on the fixing member 23, the second rib 232 is located on a side of the fixing member 23 near the piezoelectric capacitor 22, and the shape and size of the second rib 232 are designed to be able to tightly snap into the limiting hole 204 on the first limiting portion 25. In this way, the snap-fit structure formed by the second rib 232 and the limiting hole 204 can effectively restrict the circumferential (i.e., the direction around its axis) rotation of the fixing member 23, thereby ensuring the stability and reliability of the fixing member 23 after installation.

[0097] As Figure 7 and Figure 9As shown, further, the mutual cooperation between the limiting hole 204 and the second rib 232 also plays a role in precise alignment. During the installation process, the operator can ensure the correct positional relationship between the fixing member 23, the piezoelectric capacitor 22, and other related components by aligning and snapping the second rib 232 into the limiting hole 204. This design reduces errors and uncertainties during the installation process and improves the assembly accuracy of the entire capacitor assembly 2. Moreover, in addition to the snap-fit structure between the limiting hole 204 and the second rib 232, the connection strength between the fixing member 23 and the mounting shell 21 is enhanced, improving the structural rigidity and durability of the entire capacitor assembly 2.

[0098] As Figure 7 shown, in some embodiments, the first limiting portion 25 can be respectively provided on the first housing and the second housing. When the first housing and the second housing are closed together, the first limiting portion 25 can form the limiting hole 204.

[0099] As Figure 8 shown, in some embodiments, the outer wall of the second rib 232 can be closely attached to the inner wall of the limiting hole 204. In this way, when the outer wall of the second rib 232 is closely attached to the inner wall of the limiting hole 204, the contact area between the two increases, thereby providing stronger friction and resistance and effectively restricting any minute circumferential movement of the fixing member 23. During the operation of the compressor 12 or the refrigerator, it may be affected by vibrations from the outside or inside. Through the close fit between the second rib 232 and the limiting hole 204, the influence of these vibrations on the position of the fixing member 23 can be significantly reduced, preventing it from loosening or shifting due to vibrations.

[0100] As Figure 9 and Figure 10 shown, in some embodiments, the inner wall of the limiting hole 204 includes a first side wall 2051 and a second side wall 2052. The first side wall 2051 and the second side wall 2052 are adjacent to each other, and the plane where the first side wall 2051 is located is arranged at an angle with the plane where the second side wall 2052 is located to restrict the radial displacement of the second rib 232 along the limiting hole 204. By arranging the planes where the first side wall 2051 and the second side wall 2052 are located at an angle, it can be understood that the inner wall of the limiting hole 204 is not a cylindrical surface or a flat surface, but has a certain inclination or twist, which makes the fixing member encounter resistance from the two side walls when it tries to move radially due to vibration, thereby restricting the possibility of its circumferential displacement.

[0101] In some embodiments, the axial cross-section of the limiting hole 204 can be triangular, quadrilateral, pentagonal, hexagonal, etc. Correspondingly, the shape of the second rib 232 is adapted to the shape of the limiting hole 204 to restrict the radial displacement of the second rib 232 along the limiting hole 204.

[0102] As Figure 7 and Figure 9 shown, in some embodiments, the capacitor assembly 2 may include a second limiting portion 26. The second limiting portion 26 may be disposed within the mounting housing 21. The second limiting portion 26 may be located on a side of the first limiting portion 25 away from the piezoelectric capacitor 22. The fixing member 23 may be provided with a first rib 231. The first rib 231 and the second limiting portion 26 may be axially abutted against each other to prevent the fixing member 23 from axially moving toward an end close to the piezoelectric capacitor 22.

[0103] Specifically, in order to further enhance the structural stability of the capacitor assembly 2, by disposing the second limiting portion 26 within the mounting housing 21, the second limiting portion 26 can serve as an axial blocking point and abut against the first rib 231 on the fixing member 23. Among them, the lower end surface of the second limiting portion 26 is axially abutted against the upper end surface of the first rib 231, thereby restricting the fixing member 23 from axially moving toward an end close to the piezoelectric capacitor 22, helping to reduce the risk of loosening or displacement caused by vibration, impact or external force, and ensuring the reliability and durability of the capacitor assembly 2 during operation.

[0104] It should be noted that both the first limiting portion 25 and the second limiting portion 26 may be disposed within the mounting housing 21. The first limiting portion 25 and the second limiting portion 26 are axially spaced apart along the axis of the piezoelectric capacitor 22. The first limiting portion 25 is axially abutted against an end portion of the capacitor facing the fixing member 23 to restrict the piezoelectric capacitor 22 from moving toward the side where the fixing member 23 is located; the second limiting portion 26 is axially abutted against the first rib 231 of the fixing member 23 to restrict the fixing member 23 from moving toward the side where the piezoelectric capacitor 22 is located, thereby improving the overall stability of the capacitor assembly 2.

[0105] As Figure 7 shown, in some embodiments, the second limiting portion 26 may be located below the first limiting portion 25. The second limiting portion 26 may cooperate with the lower fixing member 23.

[0106] As Figure 7 shown, in some embodiments, the second limiting portion 26 may be provided with a first through hole 210. The first through hole 210 may allow the fixing member 23 to pass through.

[0107] As Figure 7 shown, in some embodiments, the second limiting portion 26 may be respectively disposed on the first housing member 211 and the second housing member 212. When the first housing and the second housing are closed together, the second limiting portion 26 may form the first through hole 210.

[0108] As Figure 7 and Figure 8As shown, in some embodiments, the capacitor assembly 2 may include a limiting rib 27. The limiting rib 27 may be disposed within the mounting housing 21. The limiting rib 27 may provide circumferential limitation to the piezoelectric capacitor 22.

[0109] As Figure 8 shown, in some embodiments, the limiting rib 27 may be circumferentially disposed along the inner peripheral wall of the mounting housing 21. The limiting rib 27 may be provided with a through hole 206. The piezoelectric capacitor 22 may pass through the through hole 206 to provide circumferential limitation to the piezoelectric capacitor 22. In this way, when the piezoelectric capacitor 22 passes through the through hole 206 of the limiting rib 27, the circumferential movement of other parts in the axial direction of the piezoelectric capacitor 22 can be effectively restricted, thereby facilitating the improvement of the relative position stability between the piezoelectric capacitor 22 and other components within the mounting housing 21.

[0110] As Figure 7 shown, in some embodiments, the shape of the through hole 206 may be adapted to the axial surface of the piezoelectric capacitor 22. For example, if the piezoelectric capacitor 22 is cylindrical as a whole, correspondingly, the shape of the through hole 206 may be set as a round hole, and the round hole may be adapted to the piezoelectric capacitor 22.

[0111] In some embodiments, multiple limiting ribs 27 may be provided.

[0112] As Figure 7 shown, in some embodiments, multiple limiting ribs 27 may be spaced apart along the axial direction of the piezoelectric capacitor 22. The capacitor passes through the through holes 206 of the multiple limiting ribs 27. By circumferentially disposing multiple limiting ribs 27 along the inner peripheral wall of the mounting housing 21, and each limiting rib 27 is provided with a through hole 206 for the piezoelectric capacitor 22 to pass through, the circumferential movement of the piezoelectric capacitor 22 can be more comprehensively restricted. In this way, the multi-point limiting method makes it more difficult for the piezoelectric capacitor 22 to shift or rotate when subjected to an external force, thereby improving the stability and reliability of the capacitor assembly 2. On the other hand, circumferentially disposing multiple limiting ribs 27 along the inner peripheral wall of the mounting housing 21 can also accommodate piezoelectric capacitors 22 of different lengths.

[0113] As Figure 8 shown, in some embodiments, one end of the fixing member 23 close to the piezoelectric capacitor 22 may be provided with a connection hole 207. The connection hole 207 may be disposed facing the side where the piezoelectric capacitor 22 is located. The piezoelectric capacitor 22 may be connected to the fixing member 23 through the connection hole 207.

[0114] As Figure 6 and Figure 8As shown, in some embodiments, a connecting post 221 may protrude from an end wall of the piezoelectric capacitor 22 facing the fixing member 23. The connecting post 221 may be inserted into the connecting hole 207 to fix the piezoelectric capacitor 22 to the fixing member 23. When connecting the piezoelectric capacitor 22 to the fixing member 23 together, by inserting the connecting post 221 into the connecting hole 207, without complex fixing steps or additional fasteners, through the cooperation of the connecting post 221 and the connecting hole 207, the piezoelectric capacitor 22 can be firmly fixed to the fixing member 23, which not only simplifies the installation process but also improves the installation efficiency.

[0115] It should be noted that the sizes of the connecting hole 207 and the connecting post 221 need to match each other so that they can be smoothly inserted together and provide a stable connection.

[0116] In some embodiments, the connecting hole 207 may be a threaded hole. The outer wall of the connecting post 221 may form a threaded wall surface. The threaded wall surface is adapted to the threaded hole. To further simplify the connection stability and convenience between the fixing member 23 and the piezoelectric capacitor 22, a threaded connection may be adopted between the connecting post 221 and the fixing member 23. During the screwing process of the threaded connection, a tight contact will be formed between the threaded wall surface of the connecting post 221 and the threads of the threaded hole, and the operation is simple. Moreover, the threaded connection has a high connection strength after being tightened, but when disassembly is required, just rotate the connecting post 221 in the reverse direction to easily pull it out of the threaded hole, which facilitates subsequent maintenance and replacement work.

[0117] As Figure 8 shown, in some embodiments, a spaced space 208 may be formed between an axial end of the piezoelectric capacitor 22 away from the fixing member 23 and the mounting shell 21.

[0118] When the piezoelectric capacitor 22 encounters extreme situations, such as external open fire or internal circuit failure resulting in a sudden increase in voltage, a large amount of heat or pressure may be generated inside the capacitor, and even an explosion may occur. By reserving the spaced space 208 between the piezoelectric capacitor 22 and the mounting shell 21, when the piezoelectric capacitor 22 encounters abnormal situations such as a sudden increase in voltage, due to reasons such as an increase in internal pressure or expansion of internal materials in the piezoelectric capacitor 22, the piezoelectric capacitor 22 axially elongates, and its internal fuse may melt due to overheating, thereby cutting off the circuit. Among them, the spaced space 208 can ensure that the piezoelectric capacitor 22 has sufficient expansion space. The designed mounting shell 21 of the present application neither hinders the explosion-proof structure of the piezoelectric capacitor 22 nor can effectively fix the piezoelectric capacitor 22, improving the safety of the piezoelectric capacitor 22.

[0119] As Figure 8As shown, in some embodiments, an electrical connection line 3 may be provided at an axial end of the piezoelectric capacitor 22 away from the fixing member 23. The electrical connection line 3 extends out of the mounting shell 21 after passing through the spacer 208. Among them, the electrical connection line 3 is a bridge between the piezoelectric capacitor 22 and the external circuit, and it is responsible for transmitting the electrical energy generated by the capacitor to where it is needed. In this way, when the piezoelectric capacitor 22 encounters abnormal conditions such as a steep increase in voltage, due to reasons such as an increase in internal pressure or expansion of internal materials in the piezoelectric capacitor 22, the piezoelectric capacitor 22 axially elongates, and its internal fuse disconnects, preventing the piezoelectric capacitor 22 from being connected to the external circuit through the electrical connection line 3 and causing danger.

[0120] As Figure 8 shown, in some embodiments, a first end wall 2091 may be formed at an axial end of the piezoelectric capacitor 22 away from the fixing member 23. The mounting shell 21 may be provided with a second end wall 2092. The first end wall 2091 and the second end wall 2092 may be axially opposed to form a spacer 208. Specifically, an axial end portion of the piezoelectric capacitor 22 provided with the electrical connection line 3 forms the first end wall 2091, and the inner surface of the mounting shell 21 is opposed to the first end wall 2091 to form the second end wall 2092. A spacer 208 is formed between the first end wall 2091 and the second end wall 2092, so that when the press resistor axially elongates due to reasons such as an increase in internal pressure or expansion of internal materials, the elongated part of the press resistor can be accommodated in the spacer 208, preventing the first end wall 2091 of the press resistor from directly abutting against the second end wall 2092 and causing the internal fuse to fail to disconnect.

[0121] As Figure 8 shown, in some embodiments, the linear distance of the spacer 208 between the first end wall 2091 and the second end wall 2092 may range from 8 mm to 12 mm. Among them, the H marked in Figure 8 the attached figure can be understood as the linear distance of the spacer 208 in this embodiment. When the spacer 208 is within this value range, it neither hinders the explosion-proof structure of the piezoelectric capacitor 22 nor causes the overall volume of the capacitor assembly 2 to be too large and occupy the internal installation space of the compressor chamber 101.

[0122] As Figure 8 shown, in some embodiments, a connection portion 28 may be provided at an axial end of the piezoelectric capacitor 22. The electrical connection line 3 is electrically connected to the piezoelectric capacitor 22 through the connection portion 28.

[0123] As Figure 8As shown, in some embodiments, the mounting shell 21 may be provided with a boss portion 213. The boss portion 213 may be disposed near one end of the connecting portion 28 provided with the piezoelectric capacitor 22. A clearance groove is provided in the boss portion 213, and the clearance groove may communicate with the spacer space 208. The electrical connection wire of the piezoelectric capacitor 22 sequentially passes through the spacer space 208 and the clearance groove and extends to the outside. By providing the boss portion 213 on the mounting shell 21 and forming a clearance groove in the boss portion 213, when the piezoelectric capacitor 22 activates the explosion-proof structure and axially elongates, the clearance groove can reserve the space for the connecting portion 28 after the piezoelectric capacitor 22 elongates, so that the connecting portion 28 can abut against the clearance groove of the boss portion 213, ensuring that the fuse inside the piezoelectric capacitor 22 can be smoothly disconnected after the piezoelectric capacitor 22 elongates.

[0124] As Figure 7 and Figure 8 shown, in some embodiments, a part of the boss portion 213 may be formed on the first shell 211, and another part of the boss portion 213 may be formed on the second shell 212. When the first shell 211 covers the second shell 212, a complete boss portion 213 can be formed and enclose a clearance groove.

[0125] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should be covered by the protection scope of the present application. Therefore, the scope of the present application is only limited by the appended claims.
