The utility model discloses only can record temperature and pressure parameter through temperature pressure detector 4, it is more convenient for two sensors are fixed alone in the past, convenient to it is little to occupy the space in air conditioner 100.

The above-mentioned temperature and pressure detector 4 is exemplified below, for example, in some embodiments of the present invention, the temperature and pressure detector 4 may include a connection assembly 41, a measurement pipe 42, at least one pressure measurement element 43, and at least one temperature measurement element 44 as shown in fig. 2. As shown in fig. 3, the connecting assembly 41 has a first through hole 45, and the wall of the first through hole 45 has at least one second through hole 46. As shown in fig. 2, the first end a of the measurement pipe 42 extends into the first through hole 45 and is connected to the connection assembly 41, and the second end b of the measurement pipe 42 extends out of the first through hole 45. The measuring pipe 42 is located in the first through hole 45, and a gap 47 is formed between a portion far away from the first end a and a side wall of the first through hole 45, and the gap 47 is communicated with the second through hole 46. At least the second end b of the measurement pipe 42 is located within the heat exchange medium. A portion of gap 47 is located within the heat exchange medium. At least one pressure measuring cell 43 is in communication with the second through hole 46. At least one temperature measuring element 44 is located within the measurement pipe 42, remote from the first end a of the measurement pipe 42.

In this case, as shown in fig. 2 and 3, the first through hole 45 of the connection member 41 is connected to the measurement pipe 42 so that the connection member 41 can be connected to the pressure measuring element 43 through the second through hole 46 of the connection member 41, and the measurement pipe 42 has a gap 47 between the side wall of the first through hole 45 and this gap 47 is communicated with the second through hole 46, so that the heat exchange medium can enter the second through hole 46 through the gap 47 to allow the pressure measuring element 43 communicated with the second through hole 46 to measure the pressure. Since the temperature measuring element 44 is located in the measuring tube 42, in this case, when measuring the pressure and temperature of the liquid inlet and outlet in the electrical equipment, the connecting assembly 41 can be fixed to the electrical equipment, and then the second end b of the measuring tube 42 and the portion of the connecting assembly 41 having the second through hole 46 extend into the heat transfer medium of the electrical equipment, at this time, the temperature measuring element 44 is located in the heat transfer medium and isolated by the measuring tube 42.

Therefore, the utility model discloses only can fix pressure measurement component 43 and temperature measurement component 44 on heat transfer pipeline 5 through coupling assembling 41 and survey buret 42 cooperation, increase the installation effectiveness. And the installation space for separately fixing the temperature measuring element 44 and the pressure measuring element 43 is saved. Moreover, the measuring tube 42 can isolate the temperature measuring element 44 from the heat exchange medium, so that the temperature measuring element 44 is prevented from affecting the performance reliability due to the dust accumulation surface under long-term operation.

In order to connect the temperature and pressure detector 4 to the pressure measuring element 43, in some embodiments of the present invention, as shown in fig. 4, the temperature and pressure detector 4 may further include at least one connecting pipe 45, the connecting pipe 45 has a third through hole 451, one end of the connecting pipe 45 is connected to the connecting assembly 41, and the third through hole 451 is communicated with the second through hole 46. The other end of the connection pipe 45 is connected to the pressure measuring element 43. It should be noted that the number of the connection pipes 45 may correspond to the number of the pressure measuring elements 43. Of course, the pressure measuring element 43 may be provided in plural, and is connected to the connection assembly 41 through plural connection pipes 45, respectively, which is not limited in this application.

In this case, as shown in fig. 4, since the sizes of the pressure measuring element 43 and the second through hole 46 of the connection assembly 41 may not match due to the variety of the pressure measuring element 43, the pressure measuring element 43 and the second through hole 46 of the connection assembly 41 may communicate with each other through the connection pipe 45. The connecting pipe 45 and the pressure measuring element 43 can be connected by threads, so that the installation and the disassembly are convenient. The connection pipe 45 and the connection assembly 41 may be at least one of welded, clamped or screwed. When welding is adopted, the sealing performance of the connecting pipe 45 and the second through hole 46 of the connecting assembly 41 is facilitated, and when threaded connection or clamping connection is adopted, the maintainability of the product is facilitated to be improved.

In some embodiments of the present invention, as shown in fig. 4, the connecting assembly 41 may include a tube structure 411, as shown in fig. 5, the tube structure 411 has a first through hole 45, and a side wall of the tube structure 411 has a second through hole 46. When the utility model discloses a demand of above-mentioned coupling assembling 41 can be satisfied when tubular structure 411.

As shown in fig. 6, when the pipe structure 411 is fixed on the heat exchange pipeline 5 shown in fig. 1, the side of the pipe structure 411 close to the second end b of the measuring pipe 42 is connected to the heat exchange pipeline 5, and can be connected by screw threads, so that the pipe structure is convenient to detach and install and easy to maintain. The second end b of the measuring tube 42 is located in the heat exchange line 5 and a part of the gap 47 between the tube structure 411 and the measuring tube 42 is located in the heat exchange medium, in which case, due to the fact that the heat exchange medium has a certain pressure in the heat exchange line 5, this gap 47 will overflow into the second through hole 46 and thus into the pressure measuring element 43 communicating with the second through hole 46, in order to detect the pressure.

Since the pipe structure 411 and the pressure measuring element 43 are located outside the heat exchange pipeline 5 after being fixed to the heat exchange pipeline 5, the end of the pipe structure 411 away from the measuring pipe 42 can be sealed to prevent dust and foreign matters from entering the measuring pipe 42, thereby affecting the measurement result of the temperature measuring element 44, and preventing the temperature measuring element 44 from being damaged by contacting the foreign matters. In this case, the connecting assembly 41 may further include a rotating tube 412 as shown in fig. 7, and the rotating tube 412 is formed with a groove 4121 and a fourth through hole 4122 communicating with the groove 4121. The side wall of the groove 4121 is connected to the end of the tube structure 411 remote from the second end b of the measurement pipe 42, and the fourth through hole 4122 communicates with the first through hole 45. The connection assembly 41 further includes a sealing member 413, and the sealing member 413 covers an end of the fourth through hole 4122 far from the measurement pipe 42 and is connected to the adaptor pipe 412.

Thus, as shown in fig. 8, the end of the adapter tube 412 with the groove 4121 may be connected to the second end b of the tube structure 411 remote from the measurement tube 42, in which case the groove 4121 may be included on the outside of the tube structure 411, so that the end of the adapter tube 412 with the groove 4121 may be screwed to the tube structure 411. In other embodiments of the present invention, a welding or clamping manner may be adopted. As long as can satisfy the connecing of adapter 412 and tubular structure 411, and the junction has the leakproofness can, the utility model discloses do not limit to this. Under the condition that the groove 4121 is connected with the tube structure 411, the fourth through hole 4122 at the other end of the connecting tube 45 is communicated with the first through hole 45, and the sealing element 413 covers one end of the fourth through hole 4122, which is far away from the measuring tube 42, and is connected with the adapter tube 412, so that the heat exchange medium in the gap 47 cannot overflow from one side of the adapter tube 412, and the sealing of the part, which is positioned outside the heat exchange pipeline 5, of the whole temperature and pressure detector 4 is ensured.

It should be noted that the side walls of the measurement tube 42 (as shown in fig. 9) illustrated in the above embodiments do not have through holes, and the heat exchange medium can be isolated from the temperature measurement element 44. In other embodiments of the present invention, a blind pipe may also be used, as shown in fig. 8, i.e. the side wall of the measuring pipe 42 has holes, so that the heat transfer medium can flow into the measuring pipe 42, so that the temperature measuring element 44 is in contact with the heat transfer medium. When the blind pipe is adopted, although the side wall of the blind pipe is provided with the hole, the pipe structure 411, the adapter pipe 412 and the sealing piece 413 form sealing at the part outside the heat exchange pipeline 5, so that the heat exchange medium cannot overflow, and the safety is ensured.

As shown in fig. 10, since the temperature measuring element 44 is located inside the measuring pipe 42, in order to make the temperature measured by the temperature measuring element 44 more accurate, in some embodiments of the present invention, the temperature measuring element 44 abuts against the inner wall of the measuring pipe 42. In this way, the heat transfer medium transfers the temperature to the side wall measuring tube 42 of the measuring tube 42, and transfers the temperature to the temperature measuring element 44, thereby realizing the temperature measurement of the heat transfer medium. In some embodiments of the present invention, the measuring tube 42 can be made of metal, so that the heat conductivity of the metal is better, and therefore, the measured temperature parameter is more accurate.

In order to enable the data measured by the sensor connecting line 48 to be sent to the control system of the air conditioner 100, in some embodiments of the present invention, the temperature measuring element 44 may be a wireless temperature sensor, and the wireless sensor and the control system of the air conditioner 100 may be wirelessly transmitted, so that the mess of the cable of the wired transmission is avoided. In other embodiments of the present invention, as shown in fig. 11, the temperature measuring element 44 may be a wired temperature sensor, and in this case, the temperature and pressure detector 4 may further include a sensor connecting wire 48, one end of which passes through the sealing member 413, and a part of which is located in the measuring pipe 42. The temperature measuring element 44 is electrically connected to a sensor connection 48. The other end of the sensor connection line 48 is electrically connected to the control system of the air conditioner 100, in which case the efficiency of the wired transmission is higher and the feedback is more sensitive. The utility model discloses can select wireless temperature sensor or wired temperature sensor according to the user's demand.

The above-mentioned pressure measuring element 43 is exemplified below, for example, in some embodiments of the present invention, the pressure measuring element 43 is a pressure sensor or a pressure switch, and the connecting ends of the existing pressure sensor or pressure switch are provided with external threads or internal threads so as to be connected with the above-mentioned connecting pipe 45. When the pressure measuring element 43 is a pressure switch, the pressure switch may send an alarm or a control signal when the measured pressure reaches a rated value, thereby ensuring the normal operation of the air conditioner 100. The working principle of the pressure switch is as follows: when the measured pressure exceeds the rated value, the free end of the elastic element generates displacement, the switch element is pushed directly or after comparison, the on-off state of the switch element is changed, and the purpose of controlling the measured pressure is achieved.

In order to more clearly express the structure of the temperature and pressure detector 4 of the present application, as shown in fig. 12, which is a front view of the temperature and pressure detector 4, the sealing member 413 is located on the left side of the X axis, the measuring pipe 42 is located on the right side of the X axis, and the connecting pipe 45 is fixed to the pipe structure 411 in the Y axis direction. As shown in fig. 13, the connection pipe 45 is positioned at an upper portion of the pipe structure 411 in the bottom view of fig. 12 of the present application, and thus the connection pipe 45 is not seen from the bottom view. As shown in fig. 14, which is a left side view of fig. 12 of the present application, since the sealing member 413 is on the left side of the adapter tube 412 in the X direction, the sealing member 413 and the adapter tube 412 can be observed in the left side view of fig. 12 of the present application, and since the cross-sectional area of the adapter tube 412 is large, the adapter tube 412 shields the structure on the right side of the adapter tube 412 in the X axis from being observed. As shown in fig. 15, which is a right side view of fig. 12 of the present application, the measurement pipe 42 can be seen on that side. In order to more clearly express the position relationship of the structures in the temperature and pressure detector 4 of the present application, as shown in fig. 16, which is a top view of fig. 12 of the present application, the connection pipe 45 is used to connect the pressure measuring element 43, and the axes of the pipe structure 411, the adapter pipe 412, the sealing member 413 and the measuring pipe 42 can be kept in a straight line, so that the connection between the structures is more stable. As shown in fig. 17, which is a perspective view of fig. 12 of the present application, the measuring tube 42 may be extended into the heat exchanging pipeline 5 when the temperature and pressure detector 4 is installed, the outer surface of the tube structure 411 may be provided with threads, and then the tube structure 411 is connected to the heat exchanging pipeline 5 through external threads, so as to achieve fixing.
