[0041] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0042] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.
[0043] In a first aspect, the present application embodiment provides a compressor assembly 1, see Figures 1 to 3 , Figure 1 The structure diagram of the compressor assembly in the embodiment of the present application is shown. Figure 2 Shows Figure 1 Schematic diagram of the cross-sectional structure in the AA direction. Figure 3 Shows Figure 1 The compressor assembly 1 is a schematic diagram of a top view of the structure of the compressor assembly, wherein the compressor assembly 1 includes a connector 10, a compressor 20, a detection component 30 and a control component.
[0044] Among them, the connector 10 is located outside the compressor 20 and is electrically connected to the compressor 20; the detection component 30 is located outside the compressor 20 and is installed on the connector 10, and the detection component 30 is used to detect whether the refrigerant is leaking; the control component is electrically connected to the detection component 30 and the compressor 20, and the control component is used to control the compressor 20 to shut down when the detection component 30 detects refrigerant leakage.
[0045] The compressor assembly 1 of the embodiment of the present application has a detection component 30 disposed on the connector 10. When the detection component 30 detects a refrigerant leakage, the control component controls the compressor 20 to shut down. In this way, after the connector 10 is electrically connected to the compressor 20, the detection component 30 on the connector 10 can promptly identify whether there is refrigerant around, and use the control component to take timely measures to respond, which can effectively improve the safety performance of the connector 10 after the electrical connection with the compressor 20.
[0046] Among them, compared with setting the detection component 30 on the compressor 20, since after the connector 10 is electrically connected to the compressor 20, the casing temperature on the compressor 20 is higher, which may have a certain impact on the use effect and / or service life of the detection component 30. Therefore, when the detection component 30 is set on the connector 10, it can ensure that the use effect of the detection component 30 is more accurate and / or does not affect the service life of the detection component 30.
[0047] Among them, the control component can control the compressor 20 to shut down by means of relays, IGBTs, and controllers. For example, taking the relay as an example, the circuit for the control component to control the compressor 20 can also include a mains power supply, a leakage protection switch, and a power supply component. The leakage protection switch is arranged between the mains power supply and the power supply component. When a refrigerant leak is found, the leakage protection switch is in an off state, the mains power supply and the power supply component are electrically disconnected, and the power supply component cannot be energized, and thus the compressor 20 cannot be powered to operate. The relay is electrically connected to the control component, and the static contact of the relay is connected to the neutral line between the mains power supply and the leakage protection switch, and the moving contact of the relay is connected to the neutral line between the leakage protection switch and the power supply component. Therefore, the opening and closing state of the leakage protection switch can be changed by changing the opening and closing state of the relay.
[0048] Specifically, when the detection component 30 detects a refrigerant leak and sends a refrigerant leak signal to the control component, the control component can control the on / off state of the relay. By changing the on / off state of the relay, the current passing through the leakage protection switch in the circuit can be changed, thereby changing the on / off state of the leakage protection switch. Further, when the leakage protection switch detects that the live current and the neutral current inside it are unbalanced, it is immediately disconnected to disconnect the electrical connection between the mains power supply and the power supply component, so that the power supply component cannot supply power to the compressor. At this time, the electrical connection between the connector and the compressor is disconnected, which can effectively prevent the leakage of refrigerant from burning due to ignition of the internal circuit after the connector and the compressor are electrically connected.
[0049] In the embodiment of the present application, the detection component 30 is installed on the side of the connector 10 away from the compressor 20. Compared with installing the detection component 30 on the side of the connector 10, the detection component 30 is farther away from the compressor 20 and is less affected by the high temperature generated when the compressor 20 is electrically connected to the connector 10, thereby not easily affecting the service life of the detection component 30.
[0050] Continue reading Figure 2 , combined with Figure 4 , Figure 4 Shows Figure 3In the cross-sectional structural diagram along the BB direction, the connector 10 is provided with a mounting groove 1111, and at least part of the detection member 30 is located in the mounting groove 1111. The setting of the mounting groove 1111 can, on the one hand, locate the installation position of the detection member 30 on the connector 10, thereby speeding up the assembly speed between the detection member 30 and the connector 10, and on the other hand, can restrain the detection member 30, making it difficult for the detection member 30 to move, thereby improving the connection reliability between the detection member 30 and the connector 10.
[0051] Furthermore, the first end face 111 of the connector 10 is provided with an installation groove 1111, and the surface 31 of the bottom of the detection member 30 away from the installation groove 1111 smoothly transitions with the first end face 111. In this way, after the detection member 30 is installed on the connector 10, the flatness of the first end face 111 of the connector 10 can be improved.
[0052] In one embodiment, the compressor assembly 1 includes a plurality of detection members 30, and the plurality of detection members 30 are arranged at intervals on the connector 10, so that the accuracy of the detection member 30 in detecting whether the refrigerant is leaking can be further improved through the plurality of detection members 30. It is understandable that, since the refrigerant content at different positions on the connector 10 is different, setting a plurality of detection members 30 for detection at different positions of the connector 10 can more comprehensively and timely identify whether there is a refrigerant leak in the surrounding area, and can further improve the safety performance of the connector 10 and the compressor 20 after plugging and connecting.
[0053] Among them, multiple detection parts 30 can be arranged on the first end surface 111 of the connector 10 away from the compressor 20; they can also be arranged on the side of the connector 10; or one part can be arranged on the first end surface 111 of the connector 10 away from the compressor 20, and the other part can be arranged on the side of the connector 10, etc., without limitation.
[0054] In one embodiment, the detection element 30 may include a refrigerant sensor, which is used to detect the refrigerant concentration in the air. The control element is electrically connected to the refrigerant sensor and is used to control the compressor 20 to stop when the refrigerant concentration exceeds a first preset value. The first preset value is an explosive content value of the refrigerant in the air.
[0055] It should be noted that when the detection member 30 includes a refrigerant sensor, it is necessary to ensure that the detection portion of the refrigerant sensor is at least partially exposed to the air, that is, the refrigerant concentration in the air can be detected only after the detection portion is in contact with the air.
[0056] In another embodiment, the detection component 30 includes a temperature sensor, which is used to detect the temperature of the air. The control component is electrically connected to the temperature sensor and is used to control the compressor 20 to stop when the temperature exceeds a second preset value.
[0057] In another embodiment, the detection member 30 includes a temperature fuse, which is used to detect the temperature of the air. When the temperature exceeds a second preset value, the fuse automatically disconnects, thereby stopping the compressor 20. It should be noted that after the temperature fuse detects that the air temperature exceeds the second preset value and automatically blows, it needs to be replaced when used again.
[0058] The compressor assembly 1 also includes an alarm component, and the control component is electrically connected to the alarm component. The setting of the alarm component can promptly issue an alarm when the detection component 30 detects refrigerant leakage, thereby further improving the safety factor after the connector 10 and the compressor 20 are electrically connected.
[0059] Continue reading Figure 2 and Figure 4 The connector 10 includes a housing 11 and a connector terminal 12. The housing 11 is formed with a first chamber 112 and a first port 113 communicating with the first chamber 112. The connector terminal 12 is located in the first chamber 112. The detection member 30 is mounted on the housing 11 of the connector 10. The compressor 20 includes a casing 21 and a compressor terminal 22. At least a portion of the compressor terminal 22 is located outside the casing 21. The compressor terminal 22 is used to pass through the first port 113 and then extend into the first chamber 112 to be electrically connected to the connector terminal 12.
[0060] The connector 10 may include at least two connector terminals 12, and the housing 11 is formed with at least two first chambers 112 equal in number to the at least two connector terminals 12, and each connector terminal 12 is installed in each first chamber 112 in a one-to-one correspondence. For example, the connector 10 includes two connector terminals 12, and the housing 11 is formed with two first chambers 112; or, the connector 10 includes three connector terminals 12, and the housing 11 is formed with three first chambers 112, and so on, without limitation.
[0061] It is understandable that when the connector 10 includes at least two connector terminals 12 , the compressor 20 includes at least two compressor terminals 22 equal in number to the at least two connector terminals 12 , and each compressor terminal 22 is electrically connected to each connector terminal 12 in a one-to-one correspondence.
[0062] The connector 10 further includes a seal 13, which is located on a side of the housing 11 close to the casing 21 and at least partially protrudes from the housing 11. When viewed along the first port 113, the seal 13 is disposed around the first port 113. The provision of the seal 13 can seal the interface between the connector 10 and the compressor 20. The portion of the seal 13 protruding from the housing 11 can be compressed when the connector 10 and the compressor 20 are connected, so as to improve the tightness of the connection between the connector 10 and the compressor 20.
[0063] It is understandable that the two opposite sides of the seal 13 can respectively abut the casing 21 of the compressor 20 and the shell 11 of the connector 10 to achieve sealing between the casing 21 of the compressor 20 and the shell 11 of the connector 10. In an exemplary solution, the shell 11 has a second end face close to the casing 21, and the second end face is formed with a first port 113. The seal 13 can be arranged on the second end face. At this time, in order to achieve a reliable connection between the seal 13 and the shell 11, the seal 13 and the shell 11 can be connected by means of adhesives or the like to prevent the seal 13 from falling off.
[0064] In another exemplary embodiment, the second end face of the shell 11 may be provided with an annular groove 1131, and part of the seal 13 may be located in the annular groove 1131. The setting of the annular groove 1131 can, on the one hand, locate the installation position of the seal 13 on the shell 11, thereby speeding up the assembly speed between the seal 13 and the shell 11; on the other hand, it can restrain the seal 13 and accommodate the deformation of the seal 13 caused by extrusion so that it is not easy to move.
[0065] It is understandable that the annular groove 1131 may be connected to the first port 113 or may not be connected to the first port 113. In the embodiment of the present application, the annular groove 1131 is not connected to the first port 113, which can prevent the seal 13 from deforming toward the first port 113 when it is squeezed and deformed, thereby affecting the installation stability of the seal 13. It should be noted that the seal 13 can be installed in the annular groove 1131 by snapping, or by bonding, etc., and this is not limited.
[0066] The portion of the seal 13 located in the annular groove 1131 may be: the seal 13 includes a first portion 131 and a second portion 132 distributed in the depth direction of the annular groove 1131, the first portion 131 may be located in the annular groove 1131, and the second portion 132 may be located outside the annular groove 1131. The second portion 132 located outside the annular groove 1131 may be deformed when the connector 10 is connected to the compressor 20, so as to improve the tightness of the connection between the connector 10 and the compressor 20.
[0067] The sealing member 13 may be installed in the annular groove 1131 by snap-fitting, or may be installed in the annular groove 1131 by bonding or other methods, which are not limited thereto.
[0068] The seal 13 may be any device with sealing performance, such as a sealing ring, etc. In the embodiment of the present application, the seal 13 is a device with elasticity and high heat resistance, wherein the seal 13 has elasticity, so that when the connector 10 is connected to the compressor 20, the seal 13 can be in a compressed state to improve the tightness of the connection between the connector 10 and the compressor 20; and the seal 13 has high heat resistance, which can prevent the seal 13 from being damaged by the heat of the surface 31 of the compressor 20, and can improve the service life of the seal 13. Specifically, the seal 13 can be a silicone rubber seal 13, which has low cost and is elastic and highly heat resistant.
[0069] In some embodiments, the housing 11 may include a first housing portion 114 and a second housing portion 115 connected to the first housing portion 114, the first housing portion 114 is closer to the casing 21 than the second housing portion 115, the first housing portion 114 has a first port 113, the heat resistance of the first housing portion 114 is higher than the heat resistance of the second housing portion 115, and the detection member 30 is installed in the second housing portion 115. The detection member 30 is installed in the second housing portion 115, so that the detection member 30 can be away from the compressor casing 21, and then in the process of electrical connection between the connector 10 and the compressor 20, the detection member 30 is not easily affected by the high temperature of the compressor casing 21, and when the detection member 30 is a temperature sensor, the detection result is more reliable.
[0070] The first housing portion 114 is formed with a first port 113 and a second port 117 communicating with the first chamber 112. The connector terminal 12 is installed in the first housing portion 114 via the second port 117. The second housing portion 115 is connected to the first housing portion 114. Disassembling the housing 11 into the first housing portion 114 and the second housing portion 115 facilitates the assembly of the connector terminal 12.
[0071] It should be noted that when at least two first chambers 112 are formed on the shell 11, the first shell portion 114 has first ports 113 equal in number to the first chambers 112 and second ports 117 equal in number to the first chambers 112, each first port 113 is connected to each first chamber 112, and each second port 117 is connected to each first chamber 112.
[0072] The heat resistance of the first housing portion 114 is higher than that of the second housing portion 115. Compared with the second housing portion 115, the first housing portion 114 is less likely to deform under high temperature conditions. Thus, the first port 113 is disposed in the first housing portion 114. When the connector 10 is connected to the compressor 20, the first housing portion 114 is close to the compressor 20. The first housing portion 114 has a higher heat resistance, which can prevent the internal connector terminal 12 from being softened by high temperature, thereby extending the service life of the connector terminal 12.
[0073] If the connector 10 includes a seal 13, the seal 13 is connected to the first housing portion 114. The seal 13 is arranged on the first housing portion 114, and even if the heat of the surface 31 of the compressor 20 is transferred to the seal 13 and the first housing portion 114, the first housing portion 114 is not easily deformed, and thus can provide a stable support effect for the seal 13, thereby ensuring the sealing performance between the compressor 20 and the connector 10, and ensuring the stability of the connection between the compressor 20 and the connector 10.
[0074] The first housing portion 114 may be made of a high heat-resistant material, for example, the first housing portion 114 may include at least one of PBT (poly butylene terephthalate) and GF (glass fiber). In the embodiment of the present application, the first housing portion 114 is made of PBT+30% GF, which is a high temperature resistant and fireproof material, and can prevent the connector terminal 12 from softening during operation.
[0075] The second housing portion 115 may cover the second port 117 and the connector terminal 12. The second port 117 is provided to facilitate the installation of the connector terminal 12 in the housing 11, and the second housing portion 115 covers the second port 117 and the connector terminal 12, so that when the connector terminal 12 and the compressor terminal 22 are connected, both are wrapped by the housing 11 of the connector 10, avoiding the presence of refrigerant near the two and the ignition problem when the connector terminal 12 and the compressor terminal 22 are connected. Among them, the first housing portion 114 may have a second end surface, and the second housing portion 115 may have a first end surface 111.
[0076] The second housing portion 115 may include an injection-molded housing portion connected to the first housing portion 114, and / or the second housing portion 115 may include a glue-filled housing portion connected to the first housing portion 114. The injection-molded housing portion is formed by an injection molding process, and the injection-molded housing portion is connected to the first housing portion 114, and the injection-molded housing portion is at least an integrally-molded structure with the first housing portion 114. Specifically, after the first housing portion 114 is molded, at least the first housing portion 114 is placed in a mold to participate in constructing a cavity for molding the injection-molded housing portion, and then a molding material is injected into the cavity to obtain the injection-molded housing portion.
[0077] The glue-filled housing portion is formed by a glue-filling process, and the glue-filled housing portion is connected to the first housing portion 114, so the glue-filled housing portion is at least an integrally molded structure with the first housing portion 114. Specifically, the first housing portion 114 is formed with a molding groove, and at least the molding groove participates in constructing a glue-filling groove for molding the glue-filled housing portion, and then the molding material is injected into the glue-filling groove to obtain the glue-filled housing portion.
[0078] In summary, whether the second housing portion 115 includes an injection-molded housing portion or a glue-filled housing portion, the second housing portion 115 and the first housing portion 114 can be formed as an integral structure, which can improve the connection tightness between the second housing portion 115 and the first housing portion 114 and the sealing between the second housing portion 115 and the first housing portion 114, compared with the second housing portion 115 and the first housing portion 114 being formed independently and then assembled. The second housing portion 115 of the connector 10 is sealed to the first housing portion 114, and when the connector 10 is connected to the compressor 20, the first housing portion 114 and the surface 31 of the compressor 20 are sealed due to the presence of the seal 13, so that the overall sealing of the connector 10 can be improved.
[0079] The second shell part 115 can be made of a sealing rubber shell with high sealing performance. The second shell part 115 can be elastic or inelastic, and can be flexibly designed according to actual needs. In the embodiment of the present application, the second shell part 115 can be made of PVC (Polyvinyl chloride), which has excellent elasticity and sealing performance. The second shell part 115 can be made of plastic or silicone, which is not limited.
[0080] In order to improve the connection reliability between the second housing part 115 and the first housing part 114, one of the second housing part 115 and the first housing part 114 may be provided with a hook 1151, and the other may be provided with a slot 1141 adapted to the hook 1151, and the hook 1151 is located in the slot 1141. The second housing part 115 and the first housing part 114 can be hooked by the hook 1151 and are not easy to be separated. It can be understood that the second housing part 115 may be provided with a hook 1151, and the first housing part 114 may be provided with a slot 1141; or the second housing part 115 may be provided with a slot 1141, and the first housing part 114 may be provided with a hook 1151, and this is not limited.
[0081] It is understandable that the second housing portion 115 can be integrally formed as an injection-molded housing portion, or the second housing portion 115 can be integrally formed as a glue-potted housing portion, so as to simplify the processing technology of the second housing portion 115 and reduce the manufacturing cost of the connector 10 .
[0082] The connector 10 also includes a cover, which covers the second port 117, and the second housing portion 115 covers the cover. Under the cover, impurities such as water vapor and dust can be prevented from entering the first housing portion 114, which would affect the performance of the connector terminal 12. When the second housing portion 115 includes an injection-molded housing portion or a glue-filled housing portion, under the cover, the molding material of the second housing portion 115 will not pass through the second port 117 to reach the connector terminal 12, and wrap the connector terminal 12, thereby ensuring effective electrical connection between the connector terminal 12 and the compressor terminal 22.
[0083] The connector terminal 12 and the cover member may be in contact or have a gap therebetween. If there is a gap between the connector terminal 12 and the cover member, the connector terminal 12 can be deformed toward the gap when plugged into the compressor terminal 22, so as to avoid damage to the connector terminal 12 and the compressor terminal 22 due to hard plugging.
[0084] The cover assembly may include a cover plate 15 , the cover plate 15 covers the second port 117 and the connector terminal 12 , and the second housing portion 115 covers the cover plate 15 .
[0085] One of the cover plate 15 and the first housing portion 114 may be provided with a limiting protrusion 151, and the other may be provided with a limiting groove 1142, and the limiting protrusion 151 is located in the limiting groove 1142. The setting of the limiting protrusion 151 and the limiting groove 1142 can position the cover plate 15 and the first housing portion 114 when they are assembled, which is conducive to improving the assembly efficiency of the cover plate 15 and the first housing portion 114. It can be understood that the limiting protrusion 151 can be provided on the cover plate 15, and the limiting groove 1142 can be provided on the first housing portion 114; or, the limiting groove 1142 can be provided on the cover plate 15, and the limiting protrusion 151 can be provided on the first housing portion 114, and this is not limited. In the embodiment of the present application, a limiting protrusion 151 is provided on the cover plate 15, and a limiting groove 1142 is provided on the first shell portion 114. Since the cover plate 15 is relatively thin, providing the limiting protrusion 151 on the cover plate 15 is more conducive to improving the structural strength of the cover plate 15 than providing the limiting groove 1142.
[0086] If the housing 11 is formed with a plurality of first chambers 112 and a plurality of second ports 117 , the cover 15 covers all the second ports 117 .
[0087] The housing 11 (e.g., the first housing portion 114) may further include a second chamber 116 in communication with the first chamber 112, the second chamber 116 being closer to the compressor 20 relative to the first chamber 112, and the cross-sectional profile of the second chamber 116 along the plugging direction being larger than the cross-sectional profiles of all the first chambers 112, and the cross-sectional profiles of all the first chambers 112 along the plugging direction being located within the cross-sectional profile of the second chamber 116. In this way, when the connector 10 includes at least two connector terminals 12 and the compressor 20 includes at least two compressor terminals 22, when the compressor terminals 22 are connected to the connector terminals 12, all the compressor terminals 22 may pass through the second chamber 116 and reach the corresponding first chamber 112 to achieve electrical connection with the corresponding connector terminals 12. Further, the compressor 20 may include a terminal seat 24 for fixing the compressor terminal 22, the terminal seat 24 protruding relative to the main body of the compressor 20, and when the compressor terminal 22 is connected to the connector terminal 12, the terminal seat 24 may be located in the second chamber 116.
[0088] It is understandable that the annular groove 1131 may or may not be connected to the second chamber 116. In the embodiment of the present application, the annular groove 1131 is not connected to the second chamber 116, which can prevent the seal 13 from deforming toward the second chamber 116 when it is squeezed and deformed, thereby affecting the installation stability of the seal 13.
[0089] The connector 10 also includes a connecting wire 16, which is electrically connected to the connector terminal 12, and is used to realize signal interaction between the compressor 20 and the outside world when the connector terminal 12 is connected to the compressor terminal 22. Among them, one end of the connecting wire 16 connected to the connector terminal 12 is wrapped by the second shell part 115 to improve the connection reliability between the connecting wire 16 and the connector terminal 12, and improve the sealing of the connector 10. Specifically, when the second shell part 115 includes an injection molding shell part and / or a glue pouring shell part, the second shell part 115 can directly wrap one end of the connecting wire 16 connected to the connector terminal 12 during injection molding and / or glue pouring. If the connector 10 includes multiple connector terminals 12, the connecting wire 16 is electrically connected to the multiple connector terminals 12.
[0090] The connector terminal 12 may be any terminal, and the compressor terminal 22 may be any terminal, as long as the compressor terminal 22 and the connector terminal 12 can be electrically connected.
[0091] For example, one of the connector terminal 12 and the compressor terminal 22 may be a male terminal, and the other may be a female terminal. In the embodiment of the present application, the connector terminal 12 is a female terminal, the compressor terminal 22 is a male terminal, the connector terminal 12 is formed with a plug hole, and at least a portion of the compressor terminal 22 is inserted into the plug hole and electrically connected to the connector terminal 12. That is, when the connector terminal 12 is connected to the compressor terminal 22, at least a portion of the compressor terminal 22 is surrounded by the connector terminal 12, which can improve the connection reliability between the connector terminal 12 and the compressor terminal 22.
[0092] See also Figure 1 , Figure 3 and Figure 4 The connector 10 further includes a first connector 14, which is provided with a connection hole 141, and the compressor 20 is provided with a second connector 23, which passes through the connection hole 141; the compressor assembly 1 further includes a locking member 40, which is located on the side of the first connector 14 away from the compressor 20 and connected to the second connector 23, so that the connector 10 presses against the compressor 20. The arrangement of the first connector 14, the second connector 23 and the locking member 40 can connect and fix the connector 10 and the compressor 20 that are plugged into each other. When the locking member 40 is locked, the second portion 132 of the seal 13 outside the annular groove 1131 can be squeezed to improve the sealing performance of the seal 13.
[0093] The second connector 23 and the locking member 40 may be connected by threads. For example, the locking member 40 includes a nut, and the second connector 23 is provided with threads. The second connector 23 passes through the connection hole 141 and is fixedly connected with the nut by threads. By tightening the nut, the distance between the compressor 20 and the connector 10 can be shortened. In addition, the first connector 14 and the second connector 23 may also be connected by plugging, snapping, etc., which is not limited.
