Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning technology, and in particular to a pipeline temperature sensing fixture and an air conditioner containing the same. Background Technology
[0002] Market research on air conditioners reveals that, constrained by installation environment and raw material costs, current residential and commercial air conditioners are trending towards smaller casings and more compact internal structures. These changes present new challenges to the R&D and manufacturing processes. Statistics show a gradual increase in the types of after-sales malfunctions and the proportion of system performance failures caused by uneven airflow, welding abnormalities, and temperature differences during factory testing over the past two years.
[0003] Currently, the industry mainly relies on linear thermocouples and aluminum foil to collect temperatures in key flow paths of condensers and evaporators to guide overall pipeline design and ensure uniform flow. The current temperature detection module relies on manual application of aluminum foil, which has the following drawbacks: 1. Sampling points are prone to moisture damage and loosening, leading to inaccurate temperature readings; 2. Sampling point locations are limited by pipeline structure and spatial constraints; 3. Increased costs and material waste, as the aluminum foil used for sampling is consumed in large quantities and cannot be reused; 4. Cumbersome operation, difficult residue cleaning, and low efficiency. Simultaneous investigations revealed that air conditioning manufacturers rarely conduct tests on temperature monitoring of various pipeline locations due to cost and efficiency concerns.
[0004] To address the pain points and shortcomings of existing methods in the industry, there is an urgent need to design a rotating, adjustable temperature sensing fixture for air conditioners. This would facilitate temperature acquisition and distribution design during the R&D process, as well as improve the accuracy of quality anomaly detection during the manufacturing process, thereby directly enhancing product performance and the user's intuitive experience. Utility Model Content
[0005] The purpose of this utility model is to provide a pipeline temperature sensing fixture and an air conditioner containing the fixture, which can rotate freely according to the pipeline bends and can automatically adjust according to the pipe diameter, so as to solve the above-mentioned technical problems existing in the prior art.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] This utility model provides a pipeline temperature sensing fixture, comprising a handle, a clamping part, and a temperature sensing element; wherein:
[0008] The handle includes a first arm and a second arm, which are hinged at the middle to form a scissor-like structure.
[0009] The clamping part is provided on the first arm and the second arm to clamp the pipeline to be tested from both sides respectively;
[0010] The temperature sensing element is disposed on part or all of the clamping portion to collect pipeline temperature.
[0011] As a further improvement of this utility model, the clamping part is rotatably connected to the handle and can rotate about an axis relative to the end of the handle.
[0012] As a further improvement of this utility model, the clamping part includes a contact layer and a support layer; wherein:
[0013] The contact layer has an arc-shaped structure that is adapted to the contour of the pipeline to be tested;
[0014] The support layer is disposed on the outside of the contact layer.
[0015] As a further improvement of this utility model, the contact layer is made of a flexible material with high elasticity and high temperature resistance.
[0016] As a further improvement of this utility model, the included angle between the centers of the lines connecting the two ends of the contact layer is not less than 90°.
[0017] As a further improvement of this utility model, the thickness of the contact layer is 3-5mm.
[0018] As a further improvement of this utility model, the clamping part and the handle are connected by a fitting rotating shaft.
[0019] As a further improvement of this utility model, the two ends of the support layer extend to form a retaining edge, and the height of the retaining edge is adapted to the thickness of the contact layer.
[0020] As a further improvement of this utility model, a receiving groove is provided on the clamping part at the contact position with the pipeline to be tested; the temperature sensing element is placed in the temperature sensing groove.
[0021] As a further improvement of this utility model, the first arm and the second arm have the same structure, both including a forearm, a middle arm and a rear arm arranged sequentially; wherein:
[0022] The forearm and the middle arm are fixedly connected and are set at an angle to each other;
[0023] The rear arm is rotatably disposed at the end of the middle arm;
[0024] A torsion spring is provided at the connection between the first arm and the second arm.
[0025] As a further improvement of this utility model, a wire-passing hole is provided on the clamping part, which is connected to the receiving groove for the cable of the temperature sensing element to pass through.
[0026] The rotary adjustable temperature sensing fixture for air conditioner pipes of this utility model has the following beneficial effects:
[0027] The sampling method is novel, with a scissor-style handle. The sampling method is novel, and the tooling can be opened by pressing one end of the handle. After releasing, the handle returns to its original position and is clamped to the pipeline to be tested by the clamping part. This temperature sensing tooling is not only easy to disassemble and improves installation efficiency, but also adopts a "clamping" fixed structure, which can effectively avoid the problem of test points loosening or falling off due to condensation and moisture on the pipe wall or vibration of the whole machine during the test. At the same time, it can improve the reliability of data acquisition and structural stability.
[0028] With strong structural versatility, the clamping part is an embedded two-layer structure. The first contact layer contacts the object being measured, and the second support layer connects to the tool handle. The contact layer uses elastic insulation material, allowing the curvature of the clamping contact surface to be automatically adjusted according to the diameter D of the pipe being measured. This enables automatic clamping adjustment based on pipe diameter, making it suitable for measuring objects of different diameters, thus demonstrating strong structural versatility. At the same time, the insulation material prevents heat loss from pipe transfer, thus avoiding abnormal temperature difference collection, and also protects the surface appearance of the measured pipeline, preventing scratches.
[0029] The wiring method is scientific and reasonable. In the design process, this utility model fully considers the working principle of the linear thermocouple, namely the Seebeck effect (when two different metal conductors are combined to form a closed circuit, an electromotive force proportional to the temperature difference is generated when there is a temperature difference between the two ends). This utility model uses a wire-passing hole reserved in the tooling clamping part for the thermocouple wire to pass through; a "square" receiving groove is designed on the contact layer. This shape can effectively increase the contact area with the object being measured (the number of holes can be increased according to the actual situation to realize multi-point temperature sampling). The size of the "hole" and the "groove" are designed completely with reference to the thermocouple wire diameter, so that the thermocouple wire is tightly attached and not easy to loosen.
[0030] Convenient and efficient operation: The temperature sensing fixture can be directly clamped to the position to be measured for reliable contact, thus effectively replacing a series of steps such as "manually wrapping the thermocouple - pasting tin foil - tying wires for fixation", achieving the goal of simplifying operation and improving work efficiency.
[0031] 5. Cost-saving through reuse: Using the temperature-sensing fixture of this utility model can save the cost of a series of materials such as tin foil and wire ties, and it can be reused, fundamentally eliminating cost waste.
[0032] The present invention provides an air conditioner, including a pipeline and a pipeline temperature sensing fixture, wherein the pipeline temperature sensing fixture is installed on the pipeline. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0048] like Figures 1-12 As shown, this utility model provides a temperature sensing fixture for a pipeline 100, including a handle, a clamping part 3, and a temperature sensing element 5; wherein:
[0049] The handle includes a first arm 1 and a second arm 2, which are hinged together at the middle to form a scissor-like structure.
[0050] The clamping parts 3 are respectively located at the ends of the first arm 1 and the second arm 2, and are arranged opposite to each other, so as to clamp the pipeline 100 to be tested from both sides; the "clamping" structure can effectively prevent the test points from loosening and falling off;
[0051] Temperature sensing element 5 is disposed on part or all of the clamping parts 3 for temperature acquisition of pipeline 100. Specifically, temperature sensing element 5 can be a thermocouple. To ensure temperature sensing effect and accuracy, temperature sensing element 5 is disposed on two clamping parts 3, and there can be one or more temperature sensing elements 5 on each clamping part 3, which can be selected according to the actual situation.
[0052] This utility model discloses a novel rotating adjustable air conditioner pipe 100 temperature sensing fixture with a scissor-type handle. The fixture can be opened by pressing one end of the handle, and after being released, the handle returns to its original position and is clamped onto the pipe 100 to be tested by the clamping part 3. This temperature sensing fixture is not only easy to disassemble and improves installation efficiency, but also adopts a "clamping" fixing structure, which can effectively avoid the problem of test points loosening or falling off due to condensation and moisture on the pipe wall or vibration of the whole machine during the test. At the same time, it can improve the reliability of data acquisition and structural stability.
[0053] Furthermore, the first arm 1 and the second arm 2 are arranged opposite to each other and are hinged together by the first connecting part 14. When one end of the first arm 1 and the second arm 2 is pressed, that is, when the ends are brought closer together, the other ends of the first arm 1 and the second arm 2, that is, the clamping part 3, move away from each other. When one end of the first arm 1 and the second arm 2 is released, the other ends of the first arm 1 and the second arm 2, that is, the clamping part 3, move closer together and clamp the pipeline 100.
[0054] To further expand its applicability and improve its flexibility of use, in this embodiment, the clamping part 3 is rotatably connected to the handle, allowing it to rotate about an axis relative to the end of the handle. Figure 1 As shown, the clamping part 3 is rotatably connected to the end of the handle via a fitting rotating shaft 4. Figure 1 From the perspective of the device, the clamping part 3 can rotate horizontally and rotate around the central axis of the interlocking rotating shaft. It can rotate freely according to the direction of the pipe 100 under test, the bending shape of the pipe 100, etc., which facilitates the placement of test points.
[0055] This structural design allows the clamping part 3 to rotate with multiple degrees of freedom relative to the first arm 1 and the second arm 2.
[0056] like Figure 10 As shown, the interlocking rotating shaft 4 includes a housing 41 and a ball bearing 42. The housing 41 is located at the end of the rear arm 13, and the ball bearing 42 is located in the middle of the clamping part 3 via a connecting post 43. The ball bearing 42 is rotatably disposed inside the housing 41 and cannot be dislodged from the housing 41 by a limiting structure. Specifically, the limiting structure can be a retaining ring set at the bottom of the housing 41, with the inner diameter of the retaining ring being smaller than the diameter of the ball bearing 42 but larger than the diameter of the connecting post 43.
[0057] In this embodiment, to further improve the applicability and operational flexibility of the tooling, and to adapt it to pipes 100 of different specifications, locations, and space constraints, the first arm 1 and the second arm 2 have the same structure, both including a front arm 11, a middle arm 12, and a rear arm 13 arranged sequentially; wherein:
[0058] The forearm 11 and the middle arm 12 are fixedly connected and are set at an angle; the angle can be a right angle or an obtuse angle; the angle between the forearm 11 and the middle arm 12 in the first arm 1 and the second arm 2 is in opposite directions; through this structure, a large opening and closing distance and angle can be formed between the first arm 1 and the second arm 2.
[0059] The rear arm 13 is rotatably mounted at the end of the middle arm 12; specifically, the rotatable structure adopts the following... Figure 8The structure includes sawtooth-shaped rotating rings on the rear arm 13 and the middle arm 12, with a rotating shaft passing through the rotating rings, so that the rear arm 13 can rotate relative to the middle arm 12. Of course, in order to prevent the rear arm 13 and the middle arm 12 from rotating too freely, the rotating shaft and the rotating ring can be set with a small gap assembly structure.
[0060] For ease of installation, such as Figure 8 As shown, the rear arm 13 is provided with a second connecting part 15 at its end, which is clamped to the housing 41 and then connected by welding or screws.
[0061] The torsion spring 7 between the first arm 1 and the second arm 2 is provided at the connection between the middle arm 12 and the forearm 11.
[0062] like Figures 1-3 , Figure 9 As shown, the forearm 11 and middle arm 12 of the first arm 1 are connected by a straight section. A U-shaped baffle 33 is provided on the straight section. A space for the torsion spring 7 is formed between the two baffles 33. A shaft hole is provided on the two baffles 33, and the rotating shaft passes through the shaft hole. The structure of the second arm 2 is the same as that of the first arm 1, and will not be described in detail here.
[0063] When in use, press the forearm 11 of the first arm 1 and the second arm 2 to bring them closer together, thereby opening the rear arm 13 of the first arm 1 and the second arm 2 outward to open the handle, making it easier to install the pipe 100. After installation, the forearm 11 can be released, at which point the rear arm 13 will come closer together and hold the pipe 100, completing the assembly of the tooling.
[0064] To accommodate pipes 100 of different diameters and to prevent damage to the pipes 100, in this embodiment, the clamping part 3 includes a contact layer 31 and a support layer 32; wherein:
[0065] The contact layer 31 has an arc-shaped structure that is adapted to the contour of the pipeline 100 under test;
[0066] The support layer 32 is located outside the contact layer 31 and can realize the function of automatic pipe diameter adjustment and clamping. It is suitable for test objects with different pipe diameters, that is, the structure has strong versatility.
[0067] Furthermore, the contact layer 31 is made of a highly elastic, high-temperature resistant flexible material, and the included angle between the centers of the lines connecting the two ends of the contact layer 31 is not less than 90°. This structural design ensures the contact area with the pipeline 100.
[0068] As a further improvement of this utility model, the contact layer 31 has a thickness of 3-5mm. By setting the contact layer 31 to a certain thickness, it not only provides insulation for the corresponding pipe 100, but also, due to the use of a variable material, it can be adapted to a larger diameter pipe 100 through deformation, thereby improving its applicability.
[0069] Considering that the contact layer 31 is a flexible material with elasticity, it is easy to warp during use. Therefore, in this embodiment, the two ends of the support layer 32 extend to form a guard edge. The height of the guard edge is adapted to the thickness of the contact layer 31. This structure is used to shield and limit the contact layer 31 to prevent it from warping.
[0070] This utility model has strong structural versatility. The clamping part 3 is an embedded two-layer structure. The first contact layer 31 contacts the object being measured, and the second support layer 32 is connected to the tool handle. The contact layer 31 uses elastic heat-insulating material, so that the curvature of the contact surface of the clamping part 3 can be automatically adjusted according to the size of the pipe diameter D being measured. It can realize the function of automatic pipe diameter adjustment clamping, and is suitable for measuring objects of different pipe diameters, that is, it has strong structural versatility. At the same time, the heat-insulating material can prevent the loss of pipe heat transfer, causing abnormal temperature difference collection, and can also protect the surface appearance quality of the measured pipe 100 and avoid scratches.
[0071] In this embodiment, a receiving groove 8 is provided on the clamping part 3 at the contact position with the pipeline 100 to be tested; the temperature sensing element 5 is placed in the temperature sensing groove. The receiving groove 8 has a square structure to increase the contact area. The reasonable wiring groove method effectively increases the measurement contact area and ensures a tight fit.
[0072] To facilitate wiring, a wire-passing hole is provided on the clamping part 3. The wire-passing hole is connected to the receiving groove 8, through which the cable 6 of the temperature sensing element 5 passes.
[0073] Furthermore, such as Figure 7 As shown, a wire-passing groove 81 is provided on one side of the receiving groove 8 to facilitate wiring.
[0074] The wiring method of this utility model is scientific and reasonable. In the design process, this utility model fully considers the working principle of the linear thermocouple, namely the Seebeck effect (when two different metal conductors are combined to form a closed circuit, an electromotive force proportional to the temperature difference will be generated when there is a temperature difference between the two ends). This utility model adopts a pre-reserved wire hole in the tooling clamping part 3 for the thermocouple wire to pass through; a "square" receiving groove 8 is designed on the contact layer 31. This shape can effectively increase the contact area with the object being measured (the number of holes can be increased according to the actual situation to realize multi-point temperature sampling). The size of the "hole" and the "groove" are designed completely with reference to the thermocouple wire diameter, so that the thermocouple wire is tightly attached and not easy to loosen.
[0075] The present invention provides an air conditioner, including a pipe 100 and a pipe 100 temperature sensing element 5, wherein the pipe 100 temperature sensing element 5 is installed on the pipe 100.
[0076] This utility model of an air conditioner uses a temperature sensing element 5 installed on a pipe 100 for temperature acquisition. The operation is convenient and efficient: the temperature sensing fixture can be directly clamped onto the measured position for reliable contact, effectively replacing the previous steps of "manually wrapping thermocouples – pasting tin foil – tying wires for fixation," thus simplifying operation and improving work efficiency. Previously, the initial setup required nearly 3.5 hours; this utility model can shorten this to 0.5 hours, increasing efficiency by 600%. Reusability saves costs: using this utility model's temperature sensing fixture saves on the cost of tin foil, wire ties, and other materials, and it can be reused, fundamentally eliminating cost waste. The fixture's reusability effectively reduces the procurement costs of tin foil, wire ties, etc.
[0077] The pipe temperature fixture of this utility model has undergone more than 2,000 long-term experimental verifications, including arranging non-standard random vibration tests to test the reliability of the test points. No abnormalities such as loosening or wear have been found, indicating that the design scheme is effective and feasible.
[0078] like Figure 12 As shown, the assembly flowchart of the pipeline 100 temperature sensing fixture testing process of this utility model is as follows:
[0079] During the use of the new temperature sensing fixture, employees only need to determine the location and number of test points of the machine under test according to the experimental testing requirements, then select the corresponding number of pipe 100 temperature sensing fixtures, clamp and arrange the points one by one, and finally insert the end of the thermocouple into the acquisition module corresponding to the fixture number. The entire point arrangement work before the test can be completed.
[0080] Whether it's a home unit, a light commercial duct unit, or a commercial multi-split unit, the entire process takes less than 30 minutes, making it highly efficient and providing more reliable testing accuracy.
