Description

Technical Field

[0001] This utility model relates to the field of air source heat pump testing technology, and in particular to an air source heat pump airflow temperature detection device. Background Technology

[0002] Air source heat pumps utilize the energy in the air to generate heat, providing a large volume, high pressure, and constant temperature of hot water to meet the diverse hot water and heating / cooling needs of the whole family 24 hours a day, while consuming minimal energy. Air source heat pumps can be classified as follows: by compressor type: fully enclosed and semi-enclosed reciprocating compressors, scroll compressors, semi-enclosed screw compressors, etc.; by unit capacity: small villa-style units and medium to large-sized units; by unit structure: integrated units and modular units.

[0003] The prior art patent CN118010178A discloses a temperature detection device for an air source heat pump, including a device body. A reading groove is formed on one outer wall of the device body, and several mounting studs are provided on the inner wall of the reading groove. A solar controller is installed inside a first mounting groove, and a battery is installed inside a second mounting groove, electrically connected through mounting holes. A wire is then used to electrically connect the solar controller and the solar panel. A digital temperature sensor is installed in the reading groove, with its temperature sensor head inserted and fixed to the inner wall of the temperature measuring pipe. Simultaneously, the hot air from the air source heat pump enters through the intake pipe and exits through the exhaust pipe, all electrically connected to the battery. The detection device facilitates disassembly and maintenance of the various working parts of the device, reducing maintenance difficulty.

[0004] However, the existing temperature measuring pipe is attached to the outside of the connection between the air inlet and outlet pipes, and the temperature is detected by the temperature measuring head at its lower end. However, the existing detection plug is simply inserted into the air source heat pump for detection. When there is a hot airflow, it will push the detection plug open, making detection difficult. In addition, the temperature measuring pipe at the air inlet and outlet pipes is attached to the outside, and the airflow will cause gas leakage at the connection, resulting in inaccurate detection data.

Triangular fixing grooves 15 are formed on the left and right sides of the irregular plug-in block 16.

[0025] Please see Figure 2 and Figure 5In this embodiment, the outer walls of both the inlet pipe 3 and the outlet pipe 4 are fitted with insulation layers 7. There are gaps at the connection points between the inlet pipe 3 and the outlet pipe 4. The sealing element includes a sealing rubber ring 17, which is inserted into the gap to enhance the seal between the inlet pipe 3 and the outlet pipe 4. A movable shaft is rotatably connected between the upper pipe 21 and the lower pipe 22. The rotational movement of the movable shaft allows the temperature measuring pipe 5 to be fitted onto the outside of the inlet pipe 3 and the outlet pipe 4. Both the inlet pipe 3 and the outlet pipe 4 are engaged in the annular groove 19 for limiting and fixing their positions. The connector includes a plug rod 23, which is inserted into... When the insertion rod 23 is inserted into the insertion hole 18, it is used to fix the upper tube 21 and the lower tube 22 to the outside of the air inlet pipe 3 and the air outlet pipe 4. The upper tube 21 and the lower tube 22 are rotated by the movable shaft so that they are sleeved on the outside of the air inlet pipe 3 and the air outlet pipe 4. The insertion rod 23 is inserted into the insertion hole 18 to complete the installation and fixation of the temperature measuring pipe 5. The sealing rubber ring 17 inside the temperature measuring pipe 5 is engaged in the gap between the air inlet pipe 3 and the air outlet pipe 4 to seal it. At the same time, the air inlet pipe 3 and the air outlet pipe 4 are engaged in the annular groove 19 to strengthen the installation and fixation of the temperature measuring pipe 5 for subsequent temperature detection.

[0026] Please see Figures 2-4 In this embodiment, the sealing element includes a sealing ring 12. A sealing groove is provided inside the positioning groove 13. The sealing ring 12 is inserted into the sealing groove. The detection plug 9 is inserted into the slot 8. Movable grooves are provided on both the left and right sides of the positioning groove 13.

At the same time as insertion, the four positioning blocks 11 on the lower end of the external connecting plate 10 of the temperature measuring head 6 and the irregular insertion block 16 are inserted into the four positioning slots 13 for fixation. Through its arc-shaped corner structure, it is pressed against the triangular insertion blocks 14 on the left and right sides inside, and the spring on one side is compressed synchronously. When the sealing ring 12 is engaged in the sealing groove, the triangular insertion block 14 pops out when the spring is relaxed and engages in the triangular fixing groove 15 to strengthen the fixation, thus completing the sealing and fixation of the detection plug 9.

[0028] Through the above steps, the sealing installation structure between the temperature measuring pipe 5 and the inlet pipe 3 and outlet pipe 4 improves the stability of the temperature measuring pipe 5 installation and enhances the sealing effect, resulting in better subsequent temperature detection efficiency. This solves the problem that the existing air source heat pump airflow temperature detection device has insufficient sealing at the connection between the detection plug 9 and the air source heat pump, as well as at the connection between the temperature measuring pipe 5 and the inlet pipe 3 and outlet pipe 4, which easily causes airflow leakage and affects the accuracy of subsequent detection data.
