Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a pipeline temperature sensing tool and an air conditioner comprising the same. Background Art

[0002] According to air conditioning market research, current residential and commercial air conditioner housing designs are trending towards smaller sizes and increasingly compact internal structures, driven by constraints such as installation environments and raw material costs. These changes present new challenges to R&D, matching, and manufacturing processes. Statistics show that over the past two years, the proportion of after-sales failures and overall unit performance failures during factory testing due to factors such as uneven flow distribution, abnormal welding, and temperature sensing variations has steadily increased.

[0003] Currently, the industry primarily relies on wire thermocouples and tin foil to collect temperatures at key flow paths in condensers and evaporators, guiding overall pipeline design for uniform flow. Current temperature detection modules rely on manual application of aluminum foil, a method with the following drawbacks: 1. The sampling point is easily loosened by moisture, resulting in distorted sampled temperatures; 2. Sampling point position deviations due to pipeline structure and spatial constraints; 3. Increased costs and material waste, as the tin foil used for sampling consumes significant amounts and cannot be reused; 4. The operation is cumbersome, residues are difficult to clean, and efficiency is low. Simultaneous survey results revealed that air conditioner manufacturers rarely conduct testing on temperature monitoring at various pipeline points due to cost and efficiency constraints.

[0004] In order to solve the pain points in the industry and the defects of existing methods, it is urgent to design a rotary and adjustable air conditioner temperature sensing tooling to achieve the convenience of temperature collection and diversion design in the R&D process, as well as the accuracy of quality abnormality detection in the production process, thereby directly improving product performance and the user's intuitive experience. Summary of the Invention

[0005] The purpose of the present invention is to provide a pipeline temperature sensing tool and an air conditioner containing the same, which can rotate freely according to the bending condition of the pipeline and can be automatically adjusted according to the size of the pipe diameter 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 solutions: The present invention provides a pipeline temperature sensing tool, comprising a handle, a clamping portion, and a temperature sensing element; wherein: The handle includes a first arm and a second arm, wherein the first arm and the second arm are hinged at their middle portions to form a scissor-type structure; The clamping portion is provided on the first arm and the second arm to clamp the pipeline to be tested from both sides respectively; The temperature sensing element is arranged on part or all of the clamping portion to collect the pipeline temperature.

[0007] As a further improvement of the present invention, the clamping portion is connected to the handle in a rotatable manner and can rotate around an axis relative to the end of the handle.

[0008] As a further improvement of the present invention, the clamping portion includes a contact layer and a support layer; wherein: The contact layer has an arc-shaped structure, which is adapted to the contour of the pipeline on the side to be tested; The supporting layer is arranged outside the contact layer.

[0009] As a further improvement of the present invention, the contact layer is made of a flexible material with high elasticity and high temperature resistance.

[0010] As a further improvement of the present invention, the center angle corresponding to the line connecting the two ends of the contact layer is not less than 90°.

[0011] As a further improvement of the present invention, the contact layer has a thickness of 3-5 mm.

[0012] As a further improvement of the present invention, the clamping portion and the handle are connected via an embedded rotating shaft.

[0013] As a further improvement of the present invention, both ends of the support layer extend to form ribs, and the height of the ribs is adapted to the thickness of the contact layer.

[0014] As a further improvement of the present invention, a receiving groove is provided on the clamping portion at a position in contact with the pipeline to be measured; and the temperature sensing element is placed in the temperature sensing groove.

[0015] As a further improvement of the present invention, the first arm and the second arm have the same structure, and both include a forearm, a middle arm and a rear arm arranged in sequence; wherein: The forearm is fixedly connected to the middle arm, and the two are arranged at an angle; The rear arm is rotatably arranged at the end of the middle arm; The torsion spring between the first arm and the second arm is provided at the connection between the middle arm and the forearm.

[0016] As a further improvement of the present invention, a wire passing hole is provided on the clamping portion, and the wire passing hole is communicated with the accommodating groove for passing the cable of the temperature sensing element.

[0017] The rotatable and adjustable air conditioner pipeline temperature sensing tooling of the present invention has the following beneficial effects: The sampling method is novel. The handle adopts a scissor-type structure. The sampling method is novel. The tooling can be opened by pressing one end of the handle. After releasing it, the handle is reset and clamped on the pipeline to be tested using the clamping part. This temperature sensing tooling is not only easy to disassemble and improve installation efficiency, but also adopts a "clamping" fixed structure, which can effectively avoid the problem of test points loosening and falling off due to condensation on the pipe wall, vibration of the whole machine, etc. during the test process. At the same time, it can improve the reliability of data collection and structural stability. The structure is highly versatile. The clamping part is an embedded two-layer structure. The first contact layer contacts the object to be measured, and the second support layer is connected to the tool handle. The contact layer uses elastic thermal insulation material, so that the curvature of the contact surface of the clamping part can be automatically adjusted according to the size of the measured pipe diameter D. The function of automatic pipe diameter adjustment and clamping can be realized, which is suitable for objects with different pipe diameters. That is, the structure is highly versatile. At the same time, the thermal insulation material can prevent the loss of pipe temperature transmission and cause abnormal temperature difference collection. It can also protect the surface appearance quality of the measured pipe and avoid scratches. The wiring method is scientific and reasonable. During the design process, the present invention fully considers the working principle of the wire thermocouple, namely the "Seebeck effect" (two different metal conductors are combined to form a closed loop. When there is a temperature difference between the two ends, an electromotive force proportional to the temperature difference is generated). The present invention reserves a wire hole in the tooling clamping position for the thermocouple wire to pass through. The "square" accommodating 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 actual conditions to achieve multi-point temperature sampling). The size of the "hole" and "groove" is designed in full reference to the diameter of the thermocouple wire, so that the thermocouple wire fits tightly and is not easy to loosen. Convenient and efficient operation: The temperature sensing tooling can be directly clamped on the measured position to achieve firm contact, thus effectively replacing the previous series of steps such as "manually winding the thermocouple - pasting tin foil - tying wires and fixing", thus simplifying the operation and improving work efficiency.

[0018] 5. Reuse and save costs: The use of the temperature-sensing tooling of the present invention can save the cost of a series of materials such as tin foil and wire ties, and can be reused, thus fundamentally eliminating cost waste.

[0019] The present invention provides an air conditioner, comprising a pipeline and the pipeline temperature sensing tool, wherein the pipeline temperature sensing tool is installed on the pipeline. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0024] like Figures 1-12 As shown, the present invention provides a pipeline 100 temperature sensing tool, including a handle, a clamping portion 3, and a temperature sensing element 5; wherein: The handle comprises a first arm 1 and a second arm 2, wherein the middle portions of the first arm 1 and the second arm 2 are hinged to form a scissor-type structure; The clamping parts 3 are respectively arranged at the ends of the first arm 1 and the second arm 2, and are arranged opposite to each other to clamp the pipeline 100 to be tested from both sides; the "clamping" structure can effectively prevent the test point from loosening and falling off; Temperature sensing elements 5 are provided on some or all of the clamping sections 3 to collect the temperature of the pipeline 100. Specifically, the temperature sensing elements 5 may be thermocouples. To ensure effective and precise temperature sensing, as well as accuracy, the temperature sensing elements 5 are provided on both clamping sections 3. The number of temperature sensing elements 5 on each clamping section 3 may be one or at least one, depending on the actual situation.

[0025] The rotary and adjustable temperature sensing fixture for the air conditioner pipeline 100 of the present invention has a novel sampling method and a handle adopts a scissor-type structure. The sampling method is novel. One end of the handle can be pressed to open the fixture, and after being released, the handle is reset and clamped on the pipeline to be tested 100 using the clamping part 3. This temperature sensing fixture is not only easy to disassemble and improves installation efficiency, but also adopts a "clamping" type fixed structure, which can effectively avoid the problem of loosening and falling off of the test point caused by condensation and moisture on the pipe wall, vibration of the whole machine, etc. during the test process, and at the same time can improve the reliability of data acquisition and structural stability.

[0026] Furthermore, the first arm 1 and the second arm 2 are disposed opposite each other and are hingedly connected via a first connecting portion 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 portion 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 portion 3, move closer together to clamp the pipeline 100.

[0027] In order to further improve the scope of application and the flexibility of use, in this embodiment, the clamping portion 3 is connected to the handle in a rotatable manner and can rotate around the axis relative to the end of the handle. Figure 1 As shown, the clamping portion 3 is rotatably connected to the end of the handle through an embedded rotating shaft 4. Figure 1 In the viewing angle, the clamping part 3 can rotate horizontally and rotate around the central axis of the embedded rotating shaft. It can be rotated at will according to the direction of the pipeline 100 of the machine under test, the bending shape of the pipeline 100, etc., which is convenient for point arrangement.

[0028] This structural arrangement enables the clamping portion 3 to rotate with multiple degrees of freedom relative to the first arm 1 and the second arm 2 .

[0029] like Figure 10As shown, the embedded rotating shaft 4 includes a shell 41 and a ball 42. The shell 41 is arranged at the end of the rear arm 13, and the ball 42 is arranged in the middle position of the clamping part 3 through the connecting column 43; the ball 42 is rotatably arranged in the shell 41, and cannot escape from the shell 41 due to the limiting structure. The specific limiting structure can be a retaining ring arranged at the bottom of the shell 41, and the inner diameter of the retaining ring is smaller than the diameter of the ball 42, but larger than the diameter of the connecting column 43.

[0030] In this embodiment, in order to further improve the scope of application and operational flexibility of the tooling and to adapt to pipelines 100 of different specifications, locations, and space restrictions, the first arm 1 and the second arm 2 have the same structure, both including a forearm 11, a middle arm 12, and a rear arm 13 arranged in sequence; wherein: The forearm 11 and the middle arm 12 are fixedly connected and arranged at an angle therebetween; the angle can be a right angle or an obtuse angle; the angles between the forearm 11 and the middle arm 12 in the first arm 1 and the second arm 2 are in opposite directions; this structure enables a larger opening and closing distance and angle to be formed between the first arm 1 and the second arm 2; The rear arm 13 is rotatably arranged at the end of the middle arm 12; specifically, the rotatable structure adopts the following Figure 8 In the structure, a serrated swivel is provided on the rear arm 13 and the middle arm 12 respectively, and a rotating shaft is passed through the swivel, 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, a small gap assembly structure can be set between the rotating shaft and the swivel.

[0031] To facilitate installation, Figure 8 As shown, a second connecting portion 15 is provided at the end of the rear arm 13 , which is clamped inside the housing 41 through the second connecting portion 15 and then connected by welding or screws.

[0032] 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 .

[0033] like Figure 1-Figure 3 、 Figure 9 As shown, the forearm 11 and the middle arm 12 of the first arm 1 are connected by a straight section, and a U-shaped baffle 33 is provided on the straight section. A space for placing the torsion spring 7 is formed between the two baffles 33, and an axial hole is provided on the two baffles 33, and the rotating shaft is passed through the axial 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.

[0034] When in use, press the forearms 11 of the first arm 1 and the second arm 2 to bring them closer to each other, thereby opening the rear arms 13 of the first arm 1 and the second arm 2 outward to open the handles, making it easier to install the pipeline 100. When the installation is completed, the forearms 11 can be released, and the rear arms 13 will move closer to each other and hold the pipeline 100, completing the assembly of the tooling.

[0035] In order to be applicable to pipelines 100 of different diameters and to prevent damage to the pipelines 100, in this embodiment, the clamping portion 3 includes a contact layer 31 and a support layer 32; wherein: The contact layer 31 has an arc-shaped structure, which is adapted to the contour of the pipeline 100 on the side to be treated; The support layer 32 is arranged outside the contact layer 31, which can realize the function of automatic adjustment and clamping of the pipe diameter, and is suitable for objects to be measured with different pipe diameters, that is, the structure has strong versatility.

[0036] Furthermore, the contact layer 31 is made of a highly elastic, high-temperature-resistant flexible material, and the central angle corresponding to the line connecting the two ends of the contact layer 31 is not less than 90°. Through this structural setting, the contact area with the pipeline 100 is guaranteed.

[0037] As a further improvement of the present invention, the thickness of the contact layer 31 is 3-5 mm. By setting the contact layer 31 to a certain thickness, it not only plays the role of heat preservation of the corresponding position pipeline 100, but also because of the use of variable materials, when the diameter of the pipeline 100 is large, it can be adapted through its deformation, thereby improving the scope of application.

[0038] Considering that the contact layer 31 is made of an elastic and flexible material and is prone to warping during use, in this embodiment, both ends of the support layer 32 extend to form ribs, the height of which matches the thickness of the contact layer 31. This structure blocks and limits the contact layer 31 to prevent it from warping.

[0039] The structure of the present invention has strong versatility. The clamping part 3 is an embedded two-layer structure. The first contact layer 31 contacts the object to be measured, and the second support layer 32 is connected to the tool handle. The contact layer 31 uses elastic thermal insulation material, so that the curvature of the contact surface of the clamping part 3 can be automatically adjusted according to the size of the measured pipe diameter D, and the function of automatic adjustment and clamping of the pipe diameter can be realized. It is suitable for objects to be measured with different pipe diameters, that is, the structure has strong versatility; at the same time, the thermal insulation material can prevent the pipe temperature from being transferred and lost, causing abnormal temperature difference collection, and can also protect the surface appearance quality of the measured pipeline 100 to avoid scratches.

[0040] In this embodiment, a receiving groove 8 is provided on the clamping portion 3 at the location where it contacts the measured pipe 100; the temperature sensing element 5 is placed within the receiving groove. The receiving groove 8 is square in shape to increase the contact area, and the rational layout and slotting effectively increase the measurement contact area and ensure a tight fit.

[0041] In order to facilitate wiring, a wire hole is provided on the clamping portion 3 , which is communicated with the accommodating groove 8 , for the cable 6 of the temperature sensing element 5 to pass through.

[0042] Furthermore, Figure 7 As shown, in order to facilitate wiring, a wire passing groove 81 is opened on one side of the accommodating groove 8.

[0043] The wiring method of the present invention is scientific and reasonable. During the design process, the present invention fully considers the working principle of the wire thermocouple, namely the "Seebeck effect" (two different metal conductors are combined to form a closed loop. When there is a temperature difference between the two ends, an electromotive force proportional to the temperature difference is generated). The present invention adopts a method of reserving a wire hole in the position of the tool clamping part 3 for the thermocouple wire to pass through; a "square" accommodating groove 8 is designed on the contact layer 31. This shape can effectively increase the contact area with the object to be measured (the number of holes can be increased according to actual conditions to achieve multi-point temperature sampling). The dimensions of the "hole" and "groove" are designed in full reference to the diameter of the thermocouple wire, so that the thermocouple wire fits tightly and is not easy to loosen.

[0044] The present invention provides an air conditioner, which includes a pipeline 100 and a temperature sensing element 5 of the pipeline 100 . The temperature sensing element 5 of the pipeline 100 is installed on the pipeline 100 .

[0045] The air conditioner of the present invention collects temperature by adopting a temperature sensing element 5 installed on the pipeline 100, which is convenient and efficient to operate: the temperature sensing tool can be directly clamped on the measured position to make firm contact, thereby effectively replacing a series of steps such as "manually winding thermocouples - pasting tin foil - tying wires and fixing" in the early stage, achieving the purpose of simplifying operation and improving work efficiency. Before the improvement, the early stage layout required nearly 3.5 hours, but the present invention can shorten it to 0.5 hours, and the efficiency is improved by 600%; reuse saves costs: the use of the temperature sensing tool of the present invention can save a series of material costs such as tin foil and wire ties, and can be reused, fundamentally eliminating cost waste. The tool can be reused, effectively reducing the procurement cost of tin foil, wire ties, etc.

[0046] The pipe temperature fixture of the present invention has been verified through long-term experiments for more than 2,000 times, including the arrangement of non-standard random vibration experiments to test the reliability of the distribution points. No loosening, wear or other abnormalities have occurred - the design scheme is effective and feasible.

[0047] like Figure 12 As shown, the pipeline 100 temperature sensing fixture test process assembly flow chart of the present invention: During the use of the new temperature-sensing tooling, employees only need to determine the location and number of test points of the machine under test according to the experimental test requirements, then select the corresponding number of pipeline 100 temperature-sensing tooling, clamp and arrange the points one by one, and finally insert the end of the thermocouple into the acquisition module corresponding to the tooling number. The entire pre-test point arrangement work can be completed.

[0048] Whether it is a household unit, a light commercial duct unit or a commercial multi-split unit, the entire process takes less than 30 minutes, with high efficiency and more reliable test accuracy.
