Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to a resistor bracket, a compressor, and an air conditioner. Background Technology

[0002] In air conditioning systems, monitoring the compressor's exhaust temperature typically relies on a thermistor located at the bend in the compressor's exhaust pipe. Because the thermistor monitors the temperature at the bend, a significant difference arises between the monitored temperature and the actual compressor temperature. This temperature discrepancy prevents the air conditioner from promptly protecting the compressor based on the monitored temperature, leading to compressor demagnetization or wear due to high temperatures.

[0003] To obtain the actual temperature of the compressor more accurately, some air conditioners attempt to use brackets to directly fix the thermistor to the top cover of the compressor. Theoretically, this method allows the thermistor to sense the compressor temperature more directly. However, the structure of the thermistor itself introduces new problems.

[0004] Because thermistors are usually fitted with a protective sleeve at their tail, the diameter of the tail is larger than that of the head. When the thermistor is fixed to the compressor top cover, the protective sleeve provides upward support, preventing the thermistor from fitting tightly against the compressor top cover. This severely affects the thermistor's detection sensitivity and ultimately impacts the air conditioning system's ability to effectively monitor and protect the compressor temperature. Utility Model Content

[0005] One objective of this invention is to overcome at least one deficiency in the prior art and to provide a resistor bracket, compressor, and air conditioner.

[0006] Another objective of this invention is to ensure that the thermistor fits tightly against the compressor top cover, thereby improving the sensitivity of temperature detection.

[0007] Another objective of this invention is to optimize the forming method of the resistor support, thereby reducing the manufacturing cost of the resistor support.

[0008] Specifically, according to a first aspect of the present invention, the present invention provides a resistor bracket for fixing a thermistor to the top cover of a compressor, the thermistor comprising a resistor body and a protective sleeve fitted onto the tail of the resistor body, and the resistor bracket comprising:

[0009] A base plate, which is attached and fixed to the upper surface of the compressor top cover; and

[0010] The housing covers the base plate and, together with the base plate, defines a slot for receiving the thermistor;

[0011] The base plate forms a step between itself and the compressor top cover through its own thickness. The step is used to accommodate the protective sleeve when the thermistor is inserted into place, so that the part of the resistor body exposed outside the protective sleeve is in contact with the upper surface of the base plate.

[0012] Optionally, the housing includes:

[0013] A top plate, which is disposed above the bottom plate; and

[0014] Two side plates extend downward from the lateral sides of the top plate and connect to the bottom plate;

[0015] The top plate, the two side plates, and the bottom plate together enclose the slot.

[0016] Optionally, the base plate includes:

[0017] Two fixing plates are located on both sides of the outer casing, each fixing plate being connected to the lower edge of its respective adjacent side plate; and

[0018] The support plate is positioned vertically opposite the top plate. When the thermistor is inserted into place, the portion of the resistor body exposed outside the protective sleeve is in contact with the upper surface of the support plate.

[0019] Optionally, each of the fixing plates is provided with at least one weld point for welding to the compressor top cover.

[0020] Optionally, the length of the support plate is greater than or equal to the length of the resistor body; and / or

[0021] The thickness of the support plate is greater than or equal to the thickness of the protective sleeve.

[0022] Optionally, the support plate includes:

[0023] Two sub-support plates are arranged laterally at intervals and are respectively fixedly connected to their respective adjacent fixed plates.

[0024] Optionally, the lateral spacing between the two sub-support plates is less than or equal to 0.5 mm.

[0025] Optionally, a process cut is provided between the side plate and the fixing plate on each side, and the sub-support plate is formed by extending at least a portion of the fixing plate near the process cut into the slot, and the extended sub-support plate is coplanar with the fixing plate.

[0026] According to a second aspect of the present invention, the present invention provides a compressor, comprising: a compressor top cover, a thermistor, and a resistor support as described above.

[0027] According to a third aspect of the present invention, the present invention provides an air conditioner including the compressor described above.

[0028] This utility model discloses a resistor support in which the base plate is fixedly attached to the upper surface of the compressor top cover, allowing heat from the compressor top cover to be transferred to the base plate in a timely manner, ensuring that the temperature of the base plate is consistent with that of the compressor top cover. The outer casing is fastened onto the base plate, together with the base plate defining a slot for accommodating the thermistor. Due to the thickness of the base plate itself, a step is naturally formed between it and the compressor top cover. When the thermistor is inserted into the slot, this step accommodates the thermistor's protective sleeve, thus offsetting the supporting effect of the protective sleeve. In this way, the portion of the resistor body exposed outside the protective sleeve can fit tightly against the upper surface of the base plate, significantly improving the sensitivity of temperature detection. The thermistor can quickly and accurately sense temperature changes in the compressor top cover, providing reliable temperature data for the stable operation of related equipment.

[0029] Furthermore, in this utility model, the resistor support has a process cutout between each side plate and the fixing plate. The sub-support plate extends into the slot from at least a portion of the fixing plate near the process cutout, and the extended sub-support plate is coplanar with the fixing plate. During manufacturing, the material removed from the side plates is not wasted but used to meet the forming requirements of the sub-support plate. This design optimizes the overall forming method of the resistor support, reducing the use of additional materials without affecting the performance of the resistor support, and effectively lowering the manufacturing cost of the resistor support.

[0046] This utility model embodiment provides a resistor bracket 2, which is mainly used to fix the thermistor 3 to the compressor top cover 1, thereby realizing real-time and accurate monitoring of the compressor temperature.

[0047] Figure 1 This is a schematic layout diagram of the installation position of the resistor bracket 2 according to an embodiment of the present invention. Figure 2 This is a schematic exploded view of the thermistor 3 and the resistor support 2 according to an embodiment of the present invention. Figure 3 This is a schematic structural diagram of the resistor support 2 according to an embodiment of the present invention. Figure 4 This is a schematic top view of the resistor support 2 according to an embodiment of the present invention. Figure 5 yes Figure 4 Schematic sectional view along the AA direction. Figure 6 This is a schematic bottom view of a resistor support 2 according to an embodiment of the present invention.

[0048] like Figures 1 to 6 As shown, the thermistor 3 typically includes a resistor body 31 and a protective sleeve 32, with the protective sleeve 32 fitted onto the tail of the resistor body 31.

[0049] The resistor body 31 is the core component of the thermistor 3, which senses temperature by measuring changes in its resistance value. When the temperature rises, the concentration of charge carriers inside the thermistor 3 increases, and the resistance value decreases; when the temperature decreases, the concentration of charge carriers inside the thermistor 3 decreases, and the resistance value increases. By connecting the thermistor 3 to the circuit and measuring the change in resistance value to obtain temperature information, functions such as monitoring and controlling the compressor temperature can be achieved.

[0050] The protective sleeve 32 is generally made of insulating, high-temperature resistant, and corrosion-resistant materials, such as silicone rubber and polytetrafluoroethylene. The protective sleeve 32 is mainly used to isolate the resistor body 31 from moisture, dust, chemicals, etc. in the surrounding environment, to prevent these substances from corroding the resistor body 31 and affecting its performance and stability, so that the thermistor 3 can work normally in various harsh environments.

[0051] The resistor support 2 generally includes a base plate 21 and a housing 22, wherein the base plate 21 is fitted and fixed to the upper surface of the compressor top cover 1, and the housing 22 is fitted onto the base plate 21 and together with the base plate 21 defines a slot 23 for accommodating the thermistor 3. The base plate 21 forms a step 231 with the compressor top cover 1 by its own thickness. The step 231 is used to accommodate the protective sleeve 32 when the thermistor 3 is inserted into place, so that the portion of the resistor body 31 exposed outside the protective sleeve 32 is in contact with the upper surface of the base plate 21.

[0052] With the above structure, the base plate 21 of the resistor support 2 is fixedly attached to the upper surface of the compressor top cover 1, allowing the heat from the compressor top cover 1 to be transferred to the base plate 21 in a timely manner, ensuring that the temperature of the base plate 21 is consistent with that of the compressor top cover 1. The outer shell 22 covers the base plate 21, together with the base plate 21 defining a slot 23 for accommodating the thermistor 3. Due to the thickness of the base plate 21, a step 231 is naturally formed between it and the compressor top cover 1. When the thermistor 3 is inserted into the slot 23, the step 231 can accommodate the protective sleeve 32 of the thermistor 3, thereby offsetting the supporting effect of the protective sleeve 32. In this way, the part of the resistor body 31 exposed outside the protective sleeve 32 can be tightly attached to the upper surface of the base plate 21, significantly improving the sensitivity of temperature detection. The thermistor 3 can quickly and accurately sense the temperature changes of the compressor top cover 1, providing reliable temperature data for the stable operation of related equipment.

[0053] The outer casing 22 may include a top plate 221 and two side plates 222, wherein the top plate 221 is disposed above the bottom plate 21, and the two side plates 222 extend downward from the lateral sides of the top plate 221 and are connected to the bottom plate 21. The top plate 221, the two side plates 222 and the bottom plate 21 together enclose the slot 23 described above.

[0054] In some alternative embodiments, the resistor support 2 can be arranged along the front-rear direction of the compressor top cover 1, and the length direction of the slot 23 is consistent with the front-rear direction of the compressor top cover 1. In this configuration, the opening at the front or rear end of the slot 23 can serve as the insertion port 232 of the slot 23, so that the thermistor 3 can be inserted into the slot 23 horizontally from front to back or from back to front, depending on the specific assembly situation.

[0055] In some alternative embodiments, the resistor support 2 can also be arranged along the left-right direction of the compressor top cover 1. In this case, the length direction of the slot 23 corresponds to the left-right direction of the compressor top cover 1. Under this arrangement, the opening at either the left or right end of the slot 23 can serve as the insertion port 232 of the slot 23, allowing the thermistor 3 to be inserted into the slot 23 horizontally from left to right or from right to left, depending on the specific assembly situation.

[0056] Of course, the arrangement of the resistor bracket 2 is not limited to the above two methods, and can be flexibly adjusted according to the actual free space around the compressor top cover 1. It can be arranged at a certain angle to the front-back direction of the compressor top cover 1, or at a certain angle to the left-right direction of the compressor top cover 1, so as to achieve an installation requirement that better fits the actual working conditions.

[0057] In some alternative embodiments, the lateral width of the slot 23 can be greater than the diameter of the resistor body 31, thereby ensuring that the resistor body 31 can be smoothly and unobstructedly inserted into the slot 23, avoiding difficulty in insertion or even damage to the resistor body 31 due to insufficient width. At the same time, the lateral width of the slot 23 can be smaller than the outer diameter of the protective sleeve 32. When the thermistor 3 is inserted into place, the protective sleeve 32 can be precisely blocked at the opening of the slot 23, so that the part of the resistor body 31 exposed outside the protective sleeve 32 can fit tightly against the upper surface of the base plate 21 inside the slot 23. This effectively ensures good thermal conductivity between the thermistor 3 and the base plate 21, enabling the thermistor 3 to sense temperature changes of the compressor top cover 1 more quickly and accurately, significantly improving the sensitivity and accuracy of temperature detection.

[0058] In some alternative embodiments, the height of the slot 23 can be designed to be the same as the diameter of the resistor body 31, meaning that the vertical distance between the lower surface of the top plate 221 and the upper surface of the bottom plate 21 is the same as the diameter of the resistor body 31. Theoretically, this design can prevent the resistor body 31 from vibrating up and down during compressor operation, thereby avoiding inaccurate detection results caused by vibration.

[0059] However, in practical applications, if the height of slot 23 is strictly set to be the same as the diameter of resistor body 31, the insertion process of thermistor 3 will often face great difficulties and it will be difficult to complete the installation smoothly.

[0060] Therefore, in this embodiment, the height of the slot 23 is optimized and adjusted to be greater than the diameter of the resistor body 31. At the same time, the top plate 221 is provided with at least one elastic pressure tongue 223 that gradually extends into the slot 23 along the insertion direction of the thermistor 3. The elastic pressure tongue 223 is configured to be gradually squeezed outward during the insertion of the thermistor 3, thereby using its own elastic force to press the thermistor 3 against the bottom plate 21.

[0061] It is understandable that during the insertion of the thermistor 3, the elastic pressure tongue 223, due to its own elasticity, generates a reaction force after being squeezed, using this elastic force to firmly press the resistor body 31 against the base plate 21. On the one hand, this effectively prevents the thermistor body 31 from losing contact with the base plate 21, ensuring that the thermistor 3 always maintains a good electrical connection; on the other hand, it also effectively prevents the thermistor 3 from accidentally coming out of the slot 23, improving the installation reliability of the thermistor 3.

[0062] In one optional embodiment, the top cover has a vertically extending window 224 for each elastic pressure tongue 223. The elastic pressure tongue 223 starts at the edge of the window 224 near the socket 232 and is set in a downward and backward tilted manner according to the insertion direction of the thermistor 3.

[0063] During the insertion of the thermistor 3, the deformation of the elastic pressure tongue 223 or whether it has been correctly pressed onto the thermistor 3 can be clearly seen through these windows 224. This not only improves the accuracy and reliability of the installation but also greatly simplifies the inspection steps during installation, making the installation process more efficient and intuitive. The design of the windows 224 can also play a role in subsequent maintenance or troubleshooting, facilitating quick location and inspection of the status of the elastic pressure tongue 223, thereby effectively reducing maintenance costs and difficulty.

[0064] Furthermore, the introduction of window 224 enhances the heat dissipation of thermistor 3 to some extent. Because window 224 provides an additional airflow path, the heat generated by thermistor 3 during operation can be dissipated more effectively, thereby reducing its operating temperature, extending its service life, and improving the accuracy of temperature detection.

[0065] The number of elastic pressure tongues 223 can be multiple, and multiple elastic pressure tongues 223 are arranged at intervals on the top plate 221 along the insertion direction of the thermistor 3.

[0066] When the thermistor 3 is inserted, it is subjected to a combined and uniform pressing force from multiple elastic pressure tongues 223. Each elastic pressure tongue 223 has a certain elasticity and restoring force. As the thermistor 3 is gradually pushed to the predetermined position, these elastic pressure tongues 223 will sequentially contact the thermistor 3 and generate appropriate pressure, thereby ensuring that the thermistor 3 is firmly clamped in the installation position. This multi-point pressing method not only improves the stability of the installation, but also helps to maintain good contact between the thermistor 3 and the compressor top cover 1, thereby optimizing its performance.

[0067] In one example, such as Figure 5 As shown, there are three elastic pressure tongues 223. The three elastic pressure tongues 223 are arranged at equal intervals on the top plate 221 along the insertion direction of the thermistor 3. The angle between each elastic pressure tongue 223 and the horizontal direction is the same, and the length of each elastic pressure tongue 223 is the same.

[0068] This uniform and regular arrangement ensures that the three elastic pressure tongues 223 can apply stable and balanced pressure to the thermistor 3 during insertion. This design not only facilitates accurate sensing of the thermistor 3's state but also enhances the stability and reliability of the entire structure, providing a solid guarantee for the efficient operation of the equipment.

[0069] Figure 7 This is a schematic structural diagram of a resistor support according to another embodiment of the present invention. Figure 8 yes Figure 7 A schematic cross-sectional view of the resistor support shown.

[0070] In another example, there are two elastic depressors 223, one of which has an angle greater than 45°, such as 60°, between its extension direction and the horizontal direction, and the other has an angle less than 45°, such as 30°, between its extension direction and the horizontal direction. The elastic depressor 223 with an angle greater than 45° is closer to the socket 232 than the elastic depressor 223 with an angle less than 45°.

[0071] To ensure that the two elastic retaining tongues 223 can apply force in the expected direction, from a length design perspective, the elastic retaining tongue 223 with an included angle greater than 45° is shorter than the elastic retaining tongue 223 with an included angle less than 45°. The shorter length combined with the larger included angle allows the elastic retaining tongue 223 closer to the socket 232 to smoothly concentrate the main force in the vertically downward direction when the thermistor 3 is inserted, thereby forming an effective vertical clamping force on the thermistor 3. The other elastic retaining tongue 223, farther from the socket 232, with a smaller included angle and a longer length, can stably apply the main force in the opposite direction of the insertion of the thermistor 3 after it is inserted into place.

[0072] With the above structure, the elastic pressure tongue 223 with an included angle greater than 45° is positioned relatively close to the socket 232. When the thermistor 3 is inserted into the socket 23, the force of the elastic pressure tongue 223 is mainly downward, ensuring that the thermistor 3 fits tightly against the bottom of the socket 23 and does not easily shift. The elastic pressure tongue 223 with an included angle less than 45° is positioned relatively far from the socket 232. After the thermistor 3 is inserted, the main force of the elastic pressure tongue 223 is opposite to the insertion direction of the thermistor 3, preventing the thermistor 3 from coming out of the socket 232. In this way, the installation stability of the thermistor 3 in the socket 23 can be improved in all aspects.

[0073] Specifically, in practical applications, when the compressor is running, the vibration of the compressor and the displacement of other components will generate a force along the insertion direction of the thermistor 3, causing the thermistor 3 to tend to dislodge from the socket 232. At this time, the elastic pressure tongue 223, whose main force is opposite to the insertion direction of the thermistor 3, generates a thrust that can counteract these dislodgement forces.

[0074] For example, when the compressor vibrates and the thermistor 3 tends to move towards the socket 232, the reverse thrust of the elastic pressure tongue 223 will prevent its movement, thus fixing it in place and preventing the thermistor 3 from coming off. Therefore, although it may seem counterintuitive, this design can effectively counteract the adverse external forces generated by the compressor operation and improve the stability of the thermistor 3 installation.

[0075] In some alternative embodiments, the base plate 21 has a baffle 215 at the end away from the socket 232, the baffle 215 being used to stop the head of the resistor body 31 when the thermistor 3 is inserted into place.

[0076] The slot 232 at one end of the slot 23 facilitates the horizontal insertion of the thermistor 3. The baffle 215 at the end of the base plate 21 away from the slot 232 can accurately stop the head of the resistor body 31 when the thermistor 3 is inserted into place, so that the thermistor 3 can be accurately inserted into the predetermined position during the installation process. Furthermore, when the compressor top cover 1 vibrates, the baffle 215 can effectively prevent the thermistor 3 from shifting, ensuring that the thermistor 3 is always in the optimal monitoring position, which greatly improves the reliability and stability of compressor temperature monitoring.

[0077] In some alternative embodiments, the base plate 21 includes two fixing plates 211 and a support plate 212. The two fixing plates 211 are located on the lateral sides of the housing 22. Each fixing plate 211 is connected to the lower edge of its adjacent side plate 222. The support plate 212 is vertically opposite to the top plate 221. When the thermistor 3 is inserted into place, the part of the resistor body 31 exposed outside the protective sleeve 32 is in contact with the upper surface of the support plate 212.

[0078] To achieve a secure connection between the base plate 21 and the compressor top cover 1, each fixing plate 211 is provided with at least one welding point 213 for welding to the compressor top cover 1. Through welding, the resistor bracket 2 can be firmly fixed to the compressor top cover 1, ensuring that the resistor bracket 2 will not shift or loosen during equipment operation, thereby continuously and stably providing a reliable mounting base for the thermistor 3.

[0079] The support plate 212 can be further subdivided into two sub-support plates 214, which are arranged laterally at intervals and are respectively fixedly connected to their respective adjacent fixing plates 211.

[0080] During the welding process, the fixed plate 211 will generate thermal stress due to the welding heat. If the sub-support plates 214 are not arranged in a spaced manner, the base plate 21 is prone to bulging upwards due to thermal stress. However, by arranging them in a spaced manner, the thermal stress can be effectively dispersed, preventing the base plate 21 from deforming as a whole. In this way, it can be ensured that the fixed plate 211 and the sub-support plates 214 are completely in contact with the upper surface of the compressor top cover 1, ensuring the connection stability and heat conduction performance between the resistor bracket 2 and the compressor top cover 1.

[0081] In some optional embodiments, a process cutout 225 is provided between the side plate 222 and the fixing plate 211 on each side. The sub-support plate 214 extends into the slot 23 from at least a portion of the fixing plate 211 near the process cutout 225, and the extended sub-support plate 214 is coplanar with the fixing plate 211. This coplanar design is of great significance, as it ensures that the sub-support plate 214 works in conjunction with the fixing plate 211 when supporting the thermistor 3, providing stable and uniform support force and avoiding displacement of the thermistor 3 due to uneven support, thereby affecting the accuracy of temperature detection.

[0082] During manufacturing, the material removed from the side plate 222 is not wasted, but used to compensate for the molding requirements of the sub-support plate 214. This design optimizes the overall molding method of the resistor bracket 2, reduces the use of additional materials without affecting the performance of the resistor bracket 2, and effectively reduces the manufacturing cost of the resistor bracket 2.

[0083] The lateral spacing between the two sub-support plates 214 is less than or equal to 0.5 mm, such as 0.2 mm, 0.4 mm, or 0.5 mm. This spacing design is to avoid excessive gaps that could adversely affect the detection accuracy of the thermistor 3. If the gap between the two sub-support plates 214 is too large, the thermistor 3 may wobble or become unstable at the gap after insertion. This would result in insufficient contact between the thermistor 3 and the support plate 212, affecting heat conduction efficiency and thus reducing the accuracy of temperature detection. By controlling the lateral spacing within the above range, it is ensured that the thermistor 3 maintains a stable position after insertion and achieves good contact with the sub-support plates 214, thereby ensuring that the thermistor 3 can accurately detect the compressor temperature.

[0084] In some embodiments, the length of the support plate 212 can be greater than or equal to the length of the resistor body 31. That is, the length of the support plate 212 is long enough to ensure that the resistor body 31 will not be partially suspended after being inserted into the slot 23 and attached to the support plate 212. The thickness of the support plate 212 can be greater than or equal to the thickness of the protective sleeve 32. After the thermistor 3 is inserted into place, the protective sleeve 32 will not obstruct the attachment of the resistor body 31 to the support plate 212 due to its own thickness, so that the resistor body 31 can be stably attached to the support plate 212.

[0085] In some embodiments, the socket of the resistor holder is designed to be tapered along the insertion direction. This unique design offers several significant technical advantages. First, during the insertion of the thermistor, the tapered socket acts as a guide structure, with its larger opening easily guiding the thermistor to accurately align with the socket, reducing insertion difficulty and improving assembly efficiency.

[0086] This utility model embodiment also provides a compressor, which may include a compressor top cover 1, a thermistor 3, and a resistor support 2 of any of the above embodiments.

[0087] The compressor using the aforementioned resistor bracket 2 allows for a more stable installation of the thermistor 3, effectively improving the accuracy and reliability of temperature detection while reducing the risk of performance degradation due to improper installation or external environmental factors.

[0088] This utility model also provides an air conditioner that includes the compressor described above.

[0089] The compressor can adjust its operating frequency according to the indoor temperature. When the indoor temperature is high, the compressor can run at a high frequency to lower the indoor temperature. The thermistor 3 is pressed against the base plate 21 and can detect the compressor's exhaust temperature in real time, thereby controlling the compressor's operating frequency based on the exhaust temperature to protect the compressor.
