Description

Technical Field

[0001] This utility model relates to the field of air conditioner temperature sensors, specifically a temperature sensor for air conditioners. Background Technology

[0002] Air conditioner temperature sensors, sometimes called temperature probes, typically use an electronic component called a negative temperature coefficient thermistor as their core component. Its characteristic is that its resistance changes with temperature. When the ambient temperature rises, its resistance decreases, and when the temperature drops, its resistance increases. By monitoring this change in resistance, the microcomputer controller of the air conditioner can accurately determine the temperature at the sensor's location.

[0003] Chinese patent announcement CN219914675U discloses a temperature sensor that is fixed to the exhaust pipe of an air conditioner outdoor unit by a pipe clamp. The sensor includes a heat shrink tubing, one end of which is connected to a transmission line; a temperature sensing head, which is cylindrical, with one end being an open end. The open end has multiple mounting pieces arranged circumferentially, and the free ends of the mounting pieces are all inclined towards the center of the temperature sensing head, forming a circular mounting hole. The other end of the heat shrink tubing is inserted into the mounting hole and is coaxially arranged with the temperature sensing head.

[0004] Regarding the aforementioned technologies, existing sensors use structures such as mounting plates to connect the transmission line and the temperature sensor head. Although this can reduce the gap compared to existing technologies, the structure is more complex, and the cost of modifying and redesigning the temperature sensor head and transmission line is also higher. Furthermore, when the sensor is installed on the copper pipe of the air conditioner using pipe clamps, the vertical length of the copper pipe is shorter than the length of the temperature sensor head when it needs to be installed at a U-shaped bend in the copper pipe, making it difficult to install the temperature sensor stably.

[0005] In summary, existing temperature sensors are not easy to install securely on the short straight section of a U-shaped bent copper tube, and the connection structure is complex and the assembly cost is high. Utility Model Content

[0006] Based on this, the purpose of this utility model is to provide a temperature sensor for air conditioners, so as to solve the technical problems that existing temperature sensors are not easy to install securely on the short straight section of a U-shaped bent copper tube, and have complex connection structures and high assembly costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a temperature sensor for an air conditioner, comprising a first clip and a second clip, the first clip and the second clip being able to be fixed to a U-shaped copper tube, further comprising a first positioning piece, the first positioning piece being installed above the first clip, and further comprising a second positioning piece, the second positioning piece being clamped between the first clip and the second clip, the first positioning piece and the second positioning piece being respectively used to fix the temperature sensing device along the axial and radial directions of the temperature sensing device.

[0008] By adopting the above technical solution, a first positioning piece and a second positioning piece with two fixed sections are set on the clamping structure to fix the temperature sensing head along the axis and radial direction of the temperature sensing head, respectively. Without changing the connection mode between the temperature sensing head and the signal line, the temperature sensing head can be easily attached to the U-shaped area of ​​the copper tube.

[0009] The present invention is further configured such that a support platform is provided at the center of the first clamping piece, and a screw hole is provided at the center of the support platform. A hand screw is connected in the screw hole, and the hand screw is used to press the first positioning piece.

[0011] The present invention is further configured such that the first positioning piece has an L-shaped structure, one end of which is provided with a positioning notch for engaging the end of the temperature sensing device, and the other end is capable of allowing a hand-tightening screw to pass through.

[0012] Preferably, the temperature sensor is positioned along the axis of the sensor using a positioning notch, which facilitates the subsequent pressing of the second positioning plate onto the temperature sensor.

[0013] The present invention is further configured such that the first positioning piece has a first waist hole at the position through which the hand-tightening screw passes.

[0014] Preferably, the position of the first positioning plate can be conveniently adjusted along the length of the temperature sensing head.

[0015] The present invention is further configured such that a guide rail is provided at the top of the second clip, and the first positioning clip is guided by the guide rail to slide along the length direction of the first waist hole.

[0016] Preferably, the sliding adjustment direction of the first positioning piece is controlled by a guide rail.

The second positioning piece is provided with a hole between the first clamping piece and the second clamping piece for a hand-tightening screw to pass through.

[0018] Preferably, the first and second clamping pieces are deformed to clamp the second positioning piece.

[0019] The present invention is further configured such that the hole through which the second positioning piece allows the hand-tightening screw to pass is a second waist hole, and the length direction of the second waist hole is the same as the length direction of the first waist hole.

[0020] Preferably, the position of the second positioning plate can be easily adjusted along the length of the temperature sensing head.

[0021] The present invention is further configured such that when the first clamping piece and the second clamping piece are not deformed, the height of the top of the support platform from the second clamping piece is greater than the thickness of the second positioning piece. Only after the second clamping piece and the first clamping piece are deformed can the second positioning piece be clamped between the first clamping piece and the second clamping piece.

[0022] Preferably, this facilitates the installation and position adjustment of the second positioning piece.

[0023] The present invention is further configured such that the first positioning piece does not come into contact with the U-shaped copper tube when the second clamping piece deforms.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] First embodiment:

[0039] A temperature sensor for air conditioners, please refer to [link / reference]. Figure 1-5 It includes a first clip 1 and a second clip 2, which can be fixed to the U-shaped copper pipe. Specifically, the U-shaped copper pipe 8 is commonly found in the serpentine bend of the heat exchange device in the air conditioner. Both ends of the first clip 1 and the second clip 2 are provided with semi-circular recessed parts, which can fit well against the outer wall of the copper pipe 8.

[0040] It also includes a first positioning piece 3, which is installed above the first clamping piece 1, and a second positioning piece 4, which is clamped between the first clamping piece 1 and the second clamping piece 2. The first positioning piece 3 and the second positioning piece 4 are used to fix the temperature sensing device along the axial and radial directions of the temperature sensing device, respectively. Specifically, the outer shell of the temperature sensing head 7 is a copper shell, which has good thermal conductivity. By pressing the two ends of the temperature sensing head 7 onto the U-shaped copper tube 8, the heat conduction of the temperature sensing head 7 by the copper tube 8 can be realized.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-5 The first clamping piece 1 has a support platform 101 with its center facing upward. The support platform 101 has a screw hole 102 at its center. The second clamping piece 2 has a through hole 202 coaxially with the screw hole 102. A hand screw 5 is connected inside the screw hole 102. The hand screw 5 is used to press the first positioning piece 3. The temperature sensor can be installed conveniently without the help of a workpiece by using the hand screw 5.

[0042] Furthermore, the first positioning piece 3 has an L-shaped structure, with a positioning notch 301 at one end for engaging the end of the temperature sensing device, and the other end allowing the hand-tightening screw 5 to pass through. The positioning notch 301 can engage the thicker part at the junction of the signal line 6 and the temperature sensing head 7. The positioning notch 301 is used to position the temperature sensing head 7 along the axial direction of the temperature sensing head 7, which facilitates the subsequent pressing of the second positioning piece 4 onto the temperature sensing head 7.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 2-3 One end of the second positioning piece 4 is used to press the temperature sensing device against the U-shaped copper tube, and the other end is located between the first clamping piece 1 and the second clamping piece 2. The second positioning piece 4 is provided with a hole between the first clamping piece 1 and the second clamping piece 2 for the hand-tightening screw 5 to pass through, so that the first clamping piece 1 and the second clamping piece 2 can deform and clamp the second positioning piece 4.

[0044] Specifically, when the first clamping piece 1 and the second clamping piece 2 are not deformed, the height of the top of the support platform 101 from the second clamping piece 2 is greater than the thickness of the second positioning piece 4. After the second clamping piece 2 and the first clamping piece 1 are deformed, the second positioning piece 4 can be clamped between the first clamping piece 1 and the second clamping piece 2, which facilitates the installation and position adjustment of the second positioning piece 4.

[0045] Second embodiment:

[0046] A temperature sensor for air conditioners, please refer to [link / reference]. Figure 1-5 Based on the first embodiment, the difference is that the first positioning piece 3 is provided with a first waist hole 302 at the position through which the hand-tightening screw 5 passes, which allows the position of the first positioning piece 3 to be easily adjusted along the length direction of the temperature sensing head 7. The hole of the second positioning piece 4 for the hand-tightening screw 5 to pass through is a second waist hole 401. The length direction of the second waist hole 401 is the same as the length direction of the first waist hole 302, which facilitates the easy adjustment of the position of the second positioning piece 4 along the length direction of the temperature sensing head 7, thereby adapting to the installation requirements of different models of temperature sensing heads, improving the fitting accuracy and clamping stability, ensuring that the temperature sensor is always in the optimal temperature measuring position during the operation of the air conditioner, and effectively avoiding loosening or measurement deviation caused by vibration or thermal expansion and contraction.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 3-5 The top of the second clip 2 is provided with a guide rail 201. The first positioning piece 3 is guided by the guide rail 201 and can slide along the length direction of the first waist hole 302. The sliding adjustment direction of the first positioning piece 3 is controlled by the guide rail 201.

[0048] Furthermore, the first positioning piece 3 does not contact the U-shaped copper tube when the second clamping piece 2 deforms, preventing the first positioning piece 3 from damaging the copper tube 8. Before deformation, the first clamping piece 1 and the second clamping piece 2 are parallel to each other. The width of the guide rail 201 is the same as the width of the end of the first positioning piece 3, allowing one end of the first positioning piece 3 to slide within the guide rail 201 while remaining parallel to the temperature sensor 7. Stable guidance is maintained during sliding to avoid misalignment and installation errors. When the hand screw 5 is tightened, it pushes the second positioning piece 4 along the second slot.

[0049] In the specific installation of this utility model: the first clamping piece 1 and the second clamping piece 2 are placed on the U-shaped bend of the copper tube 8, the position of the second positioning piece 4 with the second waist hole 401 is aligned with the screw hole 102, and then the temperature sensor 7 to be installed is attached to the copper tube 8, while the other end of the second positioning piece 4 is placed on the temperature sensor 7, one end of the first positioning piece 3 is inserted into the guide rail 201, the position of the first positioning piece 3 is slidably adjusted so that the first waist hole 302 is aligned with the through hole 202, and after passing through the hand screw 5 from top to bottom, the hand screw 5 is pre-tightened until no pressure is applied to the first positioning piece 3;

[0050] Then, first position the copper shell of the temperature sensor 7 to the middle of the U-shaped copper tube 8, so that both ends of the temperature sensor 7 can fully contact the copper tube 8. Then slide the first positioning piece 3 so that the positioning notch 301 contacts the junction of the heat shrink film of the signal line 6 and the temperature sensor 7. Initially position the temperature sensor 7 along the axial direction of the temperature sensor 7. Then continue to tighten the hand screw 5 so that the first positioning piece 3 is tightly attached to the second clamping piece 2, thereby fixing the first positioning piece 3. Slide and adjust the position of the second positioning piece 4 along the length direction of the temperature sensor 7 so that the second positioning piece 4 is close to the middle of the temperature sensor 7. Continue to tighten the hand screw 5 so that the first clamping piece 1 and the second clamping piece 2 will deform. The support platform 101 of the first clamping piece 1 will move closer to the second clamping piece 2, thereby clamping the second positioning piece 4 between the first clamping piece 1 and the second clamping piece 2. At the same time, as the end of the second positioning piece 4 moves downward, the temperature sensor 7 is further pressed against the copper tube 8.
