[0002] To ensure the efficient and stable operation of air conditioning systems, the compressor's discharge temperature and oil sump temperature are typically monitored. The temperature probe for monitoring the discharge temperature is usually installed near the discharge port inside the compressor to monitor the compressor's temperature status in real time during operation. The temperature probe for monitoring the oil sump temperature is located inside the compressor at the bottom to monitor the oil sump temperature. However, limitations imposed by the pump structure, motor, and other components make wiring the internal temperature probes of the compressor cumbersome, increasing the difficulty of wiring operations. Furthermore, some external temperature sensors attached to the compressor housing respond slowly to temperature changes, which is not conducive to real-time monitoring. Utility Model Content

[0003] Based on this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a compressor and HVAC equipment. By setting an embedded temperature sensing tube on the compressor housing, it is not only convenient to install the temperature sensing probe, but also to make the data detected by the temperature sensing probe real-time and accurate.

[0004] To achieve the above objectives, the first aspect of this utility model provides a compressor, including a compressor housing, a motor, a pump body structure, a temperature sensing bracket, and a temperature sensing probe. The motor and the pump body structure are respectively built into the interior of the compressor housing, and the motor and the pump body structure are drivenly connected. The side wall and / or top of the compressor housing are provided with a through hole. The temperature sensing bracket is a cylindrical structure with one end open.

Utilizing the embedded design and good thermal conductivity of the temperature sensing tube, the temperature probe can accurately measure the internal temperature of the compressor housing in real time when inserted into the temperature sensing tube. In other words, this utility model eliminates the need to arrange the temperature probe and its wiring inside the compressor housing, and also eliminates the need to attach an external temperature sensor to the outer wall of the compressor housing. By providing an embedded temperature sensing tube on the compressor housing, it facilitates the installation of the temperature probe and ensures that the data detected by the temperature probe is accurate and real-time.

Detailed Implementation

[0023] 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.

[0024] 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.

[0025] 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.

[0026] In related technologies, to ensure the efficient and stable operation of air conditioning systems, the compressor's exhaust temperature and oil sump temperature are typically monitored. The temperature probe for monitoring the exhaust temperature is usually installed near the exhaust port inside the compressor to monitor the compressor's temperature status in real time during operation. The temperature probe for monitoring the oil sump temperature is located inside the compressor at the bottom to monitor the oil sump temperature. However, limitations imposed by the pump structure, motor, and other components make wiring the internal temperature probes of the compressor cumbersome, increasing the difficulty of wiring operations. Furthermore, some external temperature sensors attached to the compressor housing respond slowly to temperature changes, which is not conducive to real-time monitoring.

[0027] Therefore, this utility model embodiment provides a compressor and HVAC equipment. According to this utility model embodiment, the compressor and HVAC equipment, by providing an embedded temperature sensing bracket 20 on the compressor housing 10, not only facilitates the installation of the temperature sensing probe 30, but also ensures that the data detected by the temperature sensing probe 30 is accurate and in real time.

[0028] Please see Figures 1 to 6The first aspect of this utility model provides a compressor, including a compressor housing 10, a motor 13, a pump body structure 14, a temperature sensing tube 20, and a temperature sensing probe 30. The motor 13 and the pump body structure 14 are respectively built into the interior of the compressor housing 10, and the motor 13 and the pump body structure 14 are drivenly connected. The side wall and / or top of the compressor housing 10 are provided with a through hole 11. The temperature sensing tube 20 is a cylindrical structure with one end open. The end of the temperature sensing tube 20 away from its opening is inserted into the interior of the compressor housing 10 through the through hole 11, and the outer peripheral wall of the temperature sensing tube 20 is sealed to the through hole 11. The temperature sensing probe 30 is detachably disposed in the temperature sensing tube 20.

[0029] In this embodiment, the temperature-sensing support 20 is a copper tube made of copper. The good thermal conductivity of copper allows the internal temperature of the temperature-sensing support 20 to be closer to the internal temperature of the compressor housing 10. Furthermore, in this embodiment, the outer diameter of the temperature-sensing support 20 is slightly smaller than the inner diameter of the mounting through-hole 11. This allows the temperature-sensing support 20 to pass through the mounting through-hole 11 while minimizing the gap between them. This allows the outer peripheral wall of the temperature-sensing support 20 to be welded to the outer edge of the mounting through-hole 11, sealing the gap and ensuring the airtightness of the compressor housing 10. Alternatively, in other embodiments, the outer peripheral wall of the temperature-sensing support 20 is sealed to the inner edge of the mounting through-hole 11 using solder. Or, in other embodiments, the outer peripheral wall of the temperature-sensing support 20 is sealed by welding to both the outer and inner edges of the mounting through-hole 11.

[0030] Therefore, according to the compressor of this utility model, by providing a through hole 11 through the side wall and / or top of the compressor housing 10, and by designing the temperature sensing tube 20 as a cylindrical structure with one open end, and by making the temperature sensing tube 20 a material with good thermal conductivity, the closed end of the temperature sensing tube 20 is inserted into the interior of the compressor housing 10 through the through hole 11. Utilizing the embedded design and good thermal conductivity of the temperature sensing tube 20, the temperature sensing probe 30 can accurately measure the internal temperature of the compressor housing 10 in real time when inserted into the temperature sensing tube 20. In other words, this utility model eliminates the need to arrange the temperature sensing probe 30 and its wiring inside the compressor housing 10, and also eliminates the need to attach an external temperature sensor to the outer wall of the compressor housing 10. By providing an embedded temperature sensing tube 20 on the compressor housing 10, the installation of the temperature sensing probe 30 is convenient, and the data detected by the temperature sensing probe 30 is accurate and real-time.

[0031] Optionally, in some embodiments of this utility model, the length of the temperature-sensing tube 20 is L, and the length of the portion of the temperature-sensing tube 20 extending into the compressor housing 10 is D, satisfying the relationship: 0.8L≤D≤0.95L. This can be understood as follows: the closed end of the temperature-sensing tube 20 of this utility model is mostly inserted into the interior of the compressor housing 10, leaving only the open end exposed outside the compressor housing 10. This facilitates welding of the outer peripheral wall of the temperature-sensing tube 20 to the outer edge of the mounting through hole 11 of the compressor housing 10, while ensuring that the temperature-sensing tube 20 has sufficient heat-conducting space, thereby ensuring that the internal temperature of the temperature-sensing tube 20 is closer to the internal temperature of the compressor housing 10.

[0032] Optionally, in some embodiments of this utility model, a protrusion 21 is provided on the inner wall of the temperature sensing tube 20. Correspondingly, the temperature sensing probe 30 is cylindrical in shape, and its outer diameter is slightly smaller than the inner diameter of the temperature sensing tube 20. In this way, when the temperature sensing probe 30 is inserted into the temperature sensing tube 20, the temperature sensing tube 20 can hold the temperature sensing probe 30 in place by the protrusion 21, so that the temperature sensing probe 30 is more firmly inserted into the temperature sensing tube 20.

[0033] Optionally, in some embodiments of the present invention, the area between the pump body structure 14 and the inner bottom of the compressor housing 10 is an oil sump 15, and an installation through hole 11 is provided through the side wall of the compressor housing 10 located in the oil sump 15.

[0034] Optionally, in some embodiments of the present invention, the compressor housing 10 is a cylindrical structure with an opening at the top, and an end cover 12 is provided at the opening of the compressor housing 10, with a through hole 11 through the end cover 12.

[0035] Optionally, in some embodiments of this utility model, a liquid reservoir 40 is further included. A connecting through hole is provided through the side wall of the liquid reservoir 40. The end of the temperature sensing tube 20 away from its opening is inserted into the interior of the liquid reservoir 40 through the connecting through hole, and the outer peripheral wall of the temperature sensing tube 20 is sealed to the connecting through hole.
