Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor end cover assembly, a compressor, and an air conditioning device. Background Technology

[0002] To monitor and protect the variable frequency compressor, existing air conditioning and heat pump systems typically use thermocouples on the compressor's top cover or exhaust pipe to measure the exhaust temperature. The coil temperature is then calculated from the exhaust temperature to determine the compressor's condition and protect the motor. However, due to the influence of heat transfer temperature differences and ambient temperature, the temperature measured on the compressor's outer surface (such as the top cover or exhaust pipe) differs from the actual exhaust temperature. This error is particularly pronounced at lower ambient temperatures. Especially in cases of refrigerant leakage or pump stall, the refrigerant cannot cool the motor, resulting in a high motor temperature while the outside of the top cover and exhaust pipe remains cool. Existing thermocouples cannot accurately detect these abnormalities in a timely manner, posing a significant safety risk. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0029] In the following description, when referring to the accompanying 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 this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] In related technologies, existing air conditioning and heat pump systems typically use thermocouples on the compressor's top cover or exhaust pipe to measure the exhaust temperature in order to detect and protect the inverter compressor's status. The coil temperature is then calculated from the exhaust temperature to determine the compressor's condition and protect the motor. However, due to the influence of heat transfer temperature differences and ambient temperature, the temperature measured on the compressor's outer surface (such as the top cover or exhaust pipe) differs from the actual exhaust temperature. This error is particularly pronounced when the ambient temperature is low. Especially in cases of refrigerant leakage or pump stall, the refrigerant cannot cool the motor, resulting in a high motor temperature while the temperature on the top cover or exhaust pipe remains low. Existing thermocouples cannot accurately detect these abnormal compressor conditions in a timely manner, posing a significant safety risk.

[0031] In view of this, in order to solve the problem that existing external thermocouples cannot accurately measure the exhaust temperature and motor temperature inside the compressor, this utility model provides a compressor end cover assembly, a compressor, and an air conditioning device. According to this utility model, the compressor end cover assembly, compressor, and air conditioning device measure the motor coil temperature and the compressor exhaust temperature respectively by installing a first sensor module and a second sensor module inside the compressor. The measured temperature data is continuously and periodically transmitted to the air conditioning system, which then uses the obtained temperature data to determine whether the compressor is operating normally, thereby protecting the compressor.

[0032] Please see Figures 1 to 9The first aspect of this utility model provides a compressor end cover assembly, including a compressor top cover 10 and a temperature sensor module 20. The temperature sensor module 20 is disposed inside the compressor top cover 10 and includes a first sensor module, a second sensor module, and a communication module 23. The first sensor module is used to connect to the stator winding 30 inside the compressor to measure the temperature of the stator winding 30. The second sensor module is used to measure the exhaust temperature inside the compressor. The communication module 23 extends at least partially out of the outside of the compressor top cover 10 and is connected to the first sensor module and the second sensor module respectively.

[0033] Therefore, according to the embodiment of the present invention, when the compressor end cover assembly is assembled in the compressor housing 40, the first sensor module and the second sensor module are set inside the compressor to measure the motor coil temperature and the compressor exhaust temperature respectively, and the measured temperature data is continuously and periodically transmitted to the air conditioning system through the communication module 23. The air conditioning system judges whether the compressor is operating normally based on the obtained temperature data, thereby protecting the compressor, avoiding abnormal operation of the compressor caused by excessive temperature, and effectively improving the safety and reliability of the compressor.

[0034] Specifically, in this embodiment of the invention, the temperature sensor module 20 further includes a sensor housing 21 and a microcontroller unit 22. The sensor housing 21 is disposed inside the compressor cover 10, and the microcontroller unit 22 is disposed inside the sensor housing 21. The microcontroller unit 22 is connected to the first sensor module and the second sensor module, respectively. The communication module 23 is connected to the microcontroller unit 22. Furthermore, the sensor housing 21 in this embodiment of the invention is provided with a communication connector 231, which is connected to the communication module 23. At least a portion of the communication connector 231 extends beyond the outer side of the compressor cover 10.

[0035] In other words, the temperature sensor module 20 of this embodiment integrates the microcontroller unit 22, the first sensor module, the second sensor module, and the communication module 23 onto the sensor housing 21. The first sensor module measures the temperature of the stator winding 30 of the motor and transmits the data to the microcontroller unit 22, while the second sensor module measures the exhaust temperature of the compressor and transmits the data to the microcontroller unit 22. The microcontroller unit 22 then processes the received data and calculates the corresponding temperatures of the stator winding 30 and the exhaust temperature. Finally, the communication module 23 transmits the two temperature signals to the air conditioning system. The air conditioning system then uses the obtained temperature signals to determine whether the compressor is operating normally, shutting down abnormally, or requiring maintenance, based on the set temperature range. Thus, according to this embodiment of the compressor end cover assembly, the temperature sensor module 20 can measure the exhaust temperature of the compressor and the temperature of the stator winding 30 of the motor, providing feedback on the internal temperature of the compressor. This prevents excessively high temperatures from causing abnormal compressor operation, effectively improving the safety and reliability of the compressor.

[0036] Optionally, in some embodiments of this utility model, the sensor housing 21 is provided with a first terminal 211 and a first terminal 271. The first sensor module includes a heater 25 and a first temperature sensor 24. The first terminal 211 is used to connect to one of the coils of the stator winding 30. The heater 25 is connected in series with the first terminal 211 and the first terminal 271 respectively. At least part of the first terminal 271 extends out of the outside of the compressor cover 10. The first temperature sensor 24 is in contact with the heater 25 to measure the temperature of the heater 25, and the first temperature sensor 24 is connected to the microcontroller unit 22.

[0037] In these embodiments, by providing a heater 25 and a first temperature sensor 24 on the sensor housing 21, and connecting the heater 25 in series with one set of coils of the stator winding 30 and the first terminal 271, the first temperature sensor 24 can contact and measure the heater 25. The microcontroller unit 22 then calculates the coil temperature of the stator winding 30 based on the obtained data. Furthermore, in these embodiments, the sensor housing 21 is provided with a second terminal 212, a third terminal 213, a second terminal 272, and a third terminal 273. The second terminal 212 and the third terminal 213 are respectively used to connect to the other two sets of coils of the stator winding 30. The second terminal 272 is connected to the second terminal 212, and the third terminal 273 is connected to the third terminal 213. At least a portion of the second terminal 272 and the third terminal 273 extend beyond the outer side of the compressor cover 10. In other words, in these embodiments, by integrating the first terminal 271, the second terminal 272, and the third terminal 273 onto the sensor housing 21, and by setting corresponding first terminals 211, second terminals 212, and third terminals 213 on the sensor housing 21 to connect to the three sets of coils of the stator winding 30 respectively, the temperature sensor module 20 has a higher degree of integration. This facilitates the optimization of the circuit layout and also makes it easier for the first sensor module to measure the coil temperature of the stator winding 30.

[0038] Optionally, in some embodiments of this utility model, the second sensor module includes a second temperature sensor 26. A mounting groove 28 is provided on the end face of the sensor housing 21 away from the compressor cover 10. The second temperature sensor 26 is disposed in the mounting groove 28. The second temperature sensor 26 is used to measure the exhaust temperature inside the compressor, and is connected to the microcontroller unit 22. It can be understood that in these embodiments, by exposing the second temperature sensor 26 on the sensor housing 21, the second temperature sensor 26 can directly contact the refrigerant inside the compressor, and the microcontroller unit 22 calculates the corresponding exhaust temperature of the refrigerant based on the change in resistance.

[0039] Optionally, in some embodiments of the present invention, the compressor cover 10 is provided with a sealing sleeve 27, and the first terminal 271, the second terminal 272, the third terminal 273 and the communication connector 231 are respectively sealed and passed through the sealing sleeve 27.

[0040] Optionally, in some embodiments of this utility model, the communication module 23 may be an RS485 communication module 23, and the communication connector 231 includes three communication terminals. These three terminals can be disposed through the compressor cover 10 or sealed through the sealing sleeve 27. For example, when the three communication terminals are respectively sealed through the sealing sleeve 27, they can be integrated with the first terminal 271, the second terminal 272, and the third terminal 273 on the sealing sleeve 27, making the layout of these terminals more compact and reasonable. Furthermore, in some embodiments of this utility model, the microcontroller unit 22 may be a conventional MCU chip, which will not be elaborated further here.

[0041] Optionally, in some embodiments of this invention, the first sensor module includes a third temperature sensor 29, which is connected to the coil of the stator winding 30 to measure the temperature of the stator winding 30, and is also connected to the microcontroller unit 22. It can be understood that in these embodiments, the third temperature sensor 29 directly contacts the coil of the stator winding 30, and the microcontroller unit 22 calculates the corresponding coil temperature based on the change in resistance.
