Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to an electronic control box assembly and an air conditioner. Background Technology

[0002] In related technologies, to accurately regulate indoor temperature, air conditioners are equipped with sensors to detect the indoor ambient temperature, allowing the air conditioner to adjust its operating parameters accordingly. These temperature sensors are typically installed near the air inlet or inside the display box, with corresponding wire channels and clips on the frame or inside the display box to secure the sensor's wiring harness. However, this process suffers from low efficiency when installing or removing the temperature sensor for maintenance. Furthermore, the temperature sensor is susceptible to damage from short circuits in the return air or heat generated by components on the circuit board inside the display box, leading to significant errors between the sensor's measured temperature and the actual room temperature. When the indoor temperature changes, the sensor's response to temperature changes is slow, resulting in poor temperature tracking. Therefore, improvements are needed. Utility Model Content

[0037] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0038] The following is for reference. Figures 1-6 Description of an electrical control box assembly 100 according to an embodiment of the present utility model.

[0039] Reference Figure 1 According to a first aspect embodiment of the present invention, the electrical control box assembly 100 includes: an electrical control box 1, a temperature detection assembly 2, and a wiring harness fixing assembly 3. The electrical control box 1 includes an electrical control assembly and an electrical control box body 12, with the electrical control assembly disposed inside the electrical control box body 12.

[0040] The temperature detection assembly 2 includes a temperature sensor 21 and a connecting harness. One end of the connecting harness is connected to the temperature sensor 21, and the other end is connected to the electronic control assembly. The temperature sensor 21 is located outside the electronic control housing 12. The harness fixing assembly 3 is located outside the electronic control housing 12 and includes at least one wire fixing member 30. The wire fixing member 30 includes a wire fixing part 31 and a connecting part 32 connected together. The wire fixing part 31 has a through hole 311 through which the connecting harness passes. The connecting part 32 is snapped into the electronic control housing 12.

[0041] In related technologies, in some air conditioners, the temperature detection component 2 is located at the air inlet. After the airflow, having undergone temperature exchange, leaves the air conditioner from the air outlet, some of the airflow returns to the air conditioner through the air inlet. Therefore, there is a significant difference between the temperature of the airflow passing through the air inlet and the actual indoor temperature, resulting in an error between the temperature measured by the temperature detection component 2 and the actual temperature. In other air conditioners, the temperature detection component 2 is located inside the display box. Due to the heat generated by the circuit board components inside the display box, the temperature detected by the temperature detection component 2 is higher than the actual indoor temperature.

[0042] The electrical control box assembly 100 of this application embodiment, by placing the temperature sensor 21 outside the electrical control box body 12, can reduce the influence of the temperature measured by the temperature sensor 21 on the heating of the circuit board components, and the temperature sensor 21 is not affected by the return air short circuit, which can reduce the error between the temperature measured by the temperature sensor 21 and the actual room temperature; and when the indoor temperature changes, the temperature sensor 21 can detect the change in indoor temperature more quickly, which can improve the temperature tracking performance of the temperature sensor 21.

[0043] For example, a detection hole is formed on the casing of the air conditioner, located on the side of the casing. The temperature sensor 21 includes a probe, which is opposite to the detection hole. This allows the probe to more accurately detect the indoor temperature.

[0044] The wiring harness fixing component 3 is located outside the electrical control box 12. One end of the wiring harness needs to be connected to the temperature sensor 21 located outside the electrical control box 12, and the other end is connected to the electrical control component located inside the electrical control box 12. The wiring harness fixing component 3 can fix the position of the wiring harness and prevent the wiring harness from getting tangled or interfering with other components.

[0045] For example, the wire harness fixing assembly 3 may include a wire fixing member 30; or, for another example, the wire harness fixing assembly 3 may include multiple wire fixing members 30, so that the wire harness fixing assembly 3 can more fully fix the connected wire harness.

[0046] By fixing the connecting wire harness of the temperature sensor 21 to the electrical control box 12 using the wire harness fixing assembly 3, and the wire harness fixing assembly 3 including a wire fixing part 31 and a connecting part 32, the connecting wire harness is passed through the through hole 311 of the wire fixing part 31, and the connecting part 32 is snapped into the electrical control box 12. When relevant personnel disassemble or assemble the temperature detection assembly 2, they can directly snap the connecting part 32 of the wire fixing part 30 into the electrical control box 12 or remove it from the electrical control box 12. This eliminates the need for the operation of untying the wire buckle and putting or taking the wire harness into or out of the wire slot as in related technologies, reducing the difficulty of wire management, reducing the difficulty of installation and maintenance of the temperature detection assembly 2, and improving the efficiency of installation and maintenance of the temperature detection assembly 2.

[0047] According to the embodiment of the present invention, the electrical control box assembly 100, by installing the temperature sensor 21 on the outside of the electrical control box body 12, can reduce the influence of the temperature measured by the temperature sensor 21 on the heating of the circuit board components, and the temperature sensor 21 is not affected by the return air short circuit, which can reduce the error between the temperature measured by the temperature sensor 21 and the actual room temperature, improve the temperature measurement accuracy, and improve the temperature tracking performance of the temperature sensor 21; by fixing the connecting wire harness of the temperature sensor 21 to the electrical control box body 12 by the wire harness fixing assembly 3, and the wire harness fixing assembly 3 The device includes a wire fixing part 31 and a connecting part 32. The connecting wire harness is passed through the through hole 311 of the wire fixing part 31, and the connecting part 32 is snapped into the electrical control box 12. When relevant personnel disassemble or assemble the temperature detection component 2, the connecting part 32 of the wire fixing part 30 can be directly snapped into or removed from the electrical control box 12 without the need for the operation of untying the wire buckle and putting or taking the wire harness into or out of the wire slot in related technologies. This reduces the difficulty of wire management, reduces the difficulty of installation and maintenance of the temperature detection component 2, and improves the efficiency of installation and maintenance of the temperature detection component 2.

[0048] Reference Figure 1 According to some embodiments of the present invention, at least one wire fixing member 30 is located at the end of the connecting wire harness near the temperature sensor 21. By positioning at least one wire fixing member 30 at the end of the connecting wire harness near the temperature sensor 21, the wire fixing member 30 can provide better support for the temperature sensor 21, making the temperature sensor 21 more securely fixed.

[0049] Reference Figures 1-4 According to some embodiments of the present invention, the electrical control box 12 includes an electrical control box body 121 and at least one mounting base 122. The electrical control components are disposed inside the electrical control box body 121, the temperature sensor 21 and the wire harness fixing component 3 are located outside the electrical control box body 121, the mounting base 122 is disposed on the outer wall of the electrical control box body 121, and the connecting part 32 is snapped into the mounting base 122.

[0050] For example, the wire harness fixing assembly 3 includes a wire fixing member 30, the electrical control box 12 includes a mounting base 122, and the connecting part 32 of the wire fixing member 30 is snapped into connection with the mounting base 122.

[0051] By placing the mounting base 122 on the outer wall of the electrical control box body 121 and engaging the connecting part 32 with the mounting base 122, the wire fastener 30 can fix the connecting wire harness to the outside of the electrical control box body 121 and fix the position of the wire fastener 30, thus more effectively preventing the connecting wire harness from getting tangled or interfering with other components.

[0052] Reference Figures 1-4According to some embodiments of this utility model, the mounting base 122 and the electrical control box body 121 are integrally formed. By making the mounting base 122 and the electrical control box body 121 integrally formed, the connection between the mounting base 122 and the electrical control box 1 can be more sufficient, preventing the mounting base 122 from falling off the electrical control box 1 and causing the wiring harness to become detached from its fixation.

[0053] According to some embodiments of this utility model, the number of mounting bases 122 is the same as the number of wire fixing parts 30 and they correspond one-to-one.

[0054] For example, the electrical control box 12 includes multiple mounting bases 122, which are arranged at intervals along a third direction (e.g., direction e3 in the figure). The number of wire fasteners 30 is the same as that of the mounting bases 122 and they correspond one-to-one. The connecting part 32 of each wire fastener 30 is snapped into the corresponding mounting base 122, which makes the wire fasteners 30 more effective in fixing the wire harness.

[0055] By making the number of mounting bases 122 the same as the number of wire fasteners 30 and making them correspond one-to-one, each wire fastener 30 can be fixedly connected to the corresponding mounting base 122, so that the wire fastener 30 can more fully fix the wire harness.

[0056] Reference Figures 1-4 According to some embodiments of the present invention, the electronic control assembly includes a circuit board, and the sidewall of the electronic control box body 121 includes a first sidewall 1211, which is located on the outer periphery of the circuit board. A mounting base 122 is disposed on the first sidewall 1211. By placing the first sidewall 1211 on the outer periphery of the circuit board and disposing of the mounting base 122 on the first sidewall 1211, the heat dissipated by the circuit board during operation is blocked by the first sidewall 1211, reducing the influence of the heat dissipated by the circuit board during operation on the temperature sensor 21, and making the temperature measured by the temperature sensor 21 more accurate.

[0057] Reference Figures 1-3 According to some embodiments of this utility model, a wire-passing hole 1212 for connecting wire harnesses is provided on one side of the first sidewall 1211 along its length. By providing a wire-passing hole 1212 for connecting wire harnesses on one side of the first sidewall 1211 along its length, the connecting wire harness located outside the electrical control box body 121 can pass through the wire-passing hole 1212 through the first sidewall 1211 and connect from the outside of the electrical control box body 121 to the electrical control component inside the electrical control box body 121, realizing the electrical connection between the temperature sensor 21 and the electrical control component. Furthermore, the wire-passing hole 1212 has a certain wire-fixing function, which can prevent the wire harness from getting tangled or interfering with other components.

[0058] Reference Figures 1-4According to some embodiments of the present invention, the mounting base 122 includes a snap-fit ​​structure 123, which includes a snap-fit ​​plate 1231 and a mounting groove 1233. The mounting groove 1233 is located on the side of the snap-fit ​​plate 1231 near the electrical control box body 121. A snap-fit ​​hole 1232 is formed on the snap-fit ​​plate 1231, and the connecting part 32 passes through the snap-fit ​​hole 1232, with at least a portion of the connecting part 32 accommodated in the mounting groove 1233. By having the connecting part 32 pass through the snap-fit ​​hole 1232 and with at least a portion of the connecting part 32 accommodated in the mounting groove 1233, the fixed connection between the mounting base 122 and the connecting part 32 can be made more secure, and the connection between the wire harness fixing assembly 3 and the mounting base 122 can be made more secure, thus more effectively preventing the connecting wire harness from tangling or interfering with other components.

[0059] Reference Figure 4 and Figure 6 According to some embodiments of the present invention, the connecting part 32 includes a connecting base 321 and a plug-in section 322. The plug-in section 322 has elastic deformation capability. The connecting base 321 is connected between the fixed part 31 and the plug-in section 322. The connecting base 321 is located on the side of the snap-fit ​​plate 1231 opposite to the mounting groove 1233 and is in contact with the snap-fit ​​plate 1231. The snap-fit ​​plate 1231 is provided with a snap-fit ​​hole 1232, which communicates with the mounting groove 1233. The plug-in section 322 passes through the snap-fit ​​hole 1232 and extends into the mounting groove 1233. By positioning the connecting base 321 on the side of the snap-fit ​​plate 1231 opposite to the mounting groove 1233 and in contact with it, the snap-fit ​​plate 1231 limits the connection base 321, preventing the connecting part 32 from excessively extending into the mounting groove 1233 and damaging the mounting base 122. This ensures a normal connection between the connecting part 32 and the snap-fit ​​structure 123. By giving the insertion segment 322 elastic deformation capability and allowing it to pass through the snap hole 1232 and extend into the mounting groove 1233, the insertion segment 322 can be more easily inserted into the snap hole 1232, reducing installation difficulty.

[0060] For example, when connecting and installing the connector 32 onto the mounting base 122, the plug section 322 can be pressed first to make the plug section 322 elastically deform, making it easier for the plug section 322 to pass through the locking hole 1232. Then, the plug section 322 is passed through the locking hole 1232 and extended into the mounting groove 1233. Finally, the plug section 322 is allowed to spring back naturally under the elastic action, so that the connector 32 is snapped into the locking structure 123.

[0061] For example, the inner peripheral wall of the locking hole 1232 includes a first inner peripheral wall that extends obliquely toward the geometric center of the locking hole 1232 in a first direction from the locking hole 1232 toward the locking groove. The first inner peripheral wall can guide the connecting part 32. When the connecting part 32 is connected and installed onto the mounting base 122, the insertion section 322 can be abutted against the first inner peripheral wall, and then the insertion section 322 can be pushed toward the mounting groove 1233 in the first direction. Under the guidance of the first inner peripheral wall, the insertion section 322 undergoes elastic deformation, making it easier for the insertion section 322 to be inserted into the locking hole 1232, thereby reducing the installation difficulty of the connecting part 32.

[0062] For example, the inner peripheral wall of the locking hole 1232 includes a first inner peripheral wall that extends obliquely toward the geometric center of the locking hole 1232 in a first direction from the locking hole 1232 toward the locking groove; the insertion section 322 includes a first elastic arm and a second elastic arm that extend obliquely toward the direction closer to the second elastic arm in the first direction from the locking hole 1232 toward the locking groove, and the second elastic arm extends obliquely toward the direction closer to the first elastic arm. This allows the first inner peripheral wall to provide more effective guidance for the connecting part 32 and reduces the installation difficulty of the connecting part 32.

[0063] Reference Figure 1 and Figure 6 According to some embodiments of the present invention, the plug segment 322 includes a first plug segment 3221 and a second plug segment 3222. The first plug segment 3221 is connected between the second plug segment 3222 and the connecting base 321. A limiting surface 323 is formed between the first plug segment 3221 and the second plug segment 3222. The first plug segment 3221 passes through the card hole 1232. The second plug segment 3222 is located in the mounting groove 1233. The limiting surface 323 is located on the side of the card plate 1231 facing the mounting groove 1233 and is in contact with the card plate 1231.

[0064] For example, the plug-in segment 322 includes a first elastic arm, a second elastic arm, a support arm, and a head. The first elastic arm and the second elastic arm are opposite to each other and spaced apart. The support arm is located between the first elastic arm and the second elastic arm. The first elastic arm, the second elastic arm, and the support arm are all connected between the head and the connecting base 321. A portion of the first elastic arm, the second elastic arm, and the support arm constitutes the first plug-in segment 3221. The other portion of the first elastic arm, the second elastic arm, and the support arm, plus the head, constitutes the second plug-in segment 3222. Both the first elastic arm and the second elastic arm form a finite surface 323.

[0065] For example, the first elastic arm and the second elastic arm have elastic deformation capabilities, while the support arm does not have elastic deformation capabilities. The support arm can increase the structural strength of the plug segment 322 and more fully prevent the plug segment 322 from being damaged due to excessive deformation.

[0066] For example, when connecting and installing the connecting part 32 to the snap-fit ​​structure 123, the first elastic arm and the second elastic arm can be pressed first to deform the first elastic arm and the second elastic arm, making it easier for the insertion section 322 to pass through the snap-fit ​​hole 1232. Then, the insertion section 322 is passed through the snap-fit ​​hole 1232 and the second insertion section 3222 is extended into the mounting groove 1233. Finally, the first elastic arm and the second elastic arm are allowed to spring back naturally under the action of elasticity. At this time, the limiting surface 323 contacts the snap-fit ​​plate 1231, and the connecting part 32 cannot be directly dislodged from the snap-fit ​​structure 123, so that the connecting part 32 is snapped into the snap-fit ​​structure 123.

[0067] By forming a limiting surface 323 between the first insertion segment 3221 and the second insertion segment 3222, and by making the limiting surface 323 contact the snap-fit ​​plate 1231, when the connecting part 32 tends to detach from the snap-fit ​​structure 123, the limiting surface 323 abuts against the snap-fit ​​plate 1231, and the snap-fit ​​plate 1231 can prevent the connecting part 32 from detaching from the snap-fit ​​structure 123, making the connection between the connecting part 32 and the mounting base 122 more secure.

[0068] Reference Figure 4 According to some embodiments of the present invention, the snap-fit ​​plate 1231 and the mounting groove 1233 are arranged along a first direction (e.g., the e1 direction in the figure). The mounting groove 1233 is open on one side along a second direction (e.g., the e2 direction in the figure) to form a groove opening 1234. The groove opening 1234 and the snap hole 1232 are respectively located on adjacent sides of the mounting base 122. A disassembly notch 1235 is formed at one end of the snap-fit ​​plate 1231 near the groove opening 1234. The disassembly notch 1235 and the snap hole 1232 are arranged along the second direction, and the disassembly notch 1235 connects the snap hole 1232 and the groove opening 1234. The disassembly notch 1235 is used for the insertion section 322 to pass through and disengage from the mounting base 122. The first direction and the second direction intersect.

[0069] Since the limiting surface 323 is in contact with the snap-fit ​​plate 1231, when the connecting part 32 tends to detach from the snap-fit ​​structure 123 in the first direction, the snap-fit ​​plate 1231 prevents the connecting part 32 from detaching from the snap-fit ​​structure 123. The connecting part 32 is not easy to detach from the snap-fit ​​structure 123 by moving in the first direction. By opening the mounting groove 1233 on one side in the second direction to form a groove opening 1234, and by forming a disassembly notch 1235 at the end of the snap-fit ​​plate 1231 near the groove opening 1234, the disassembly notch 1235 connects the snap hole 1232 and the groove opening 1234, so that the connecting part 32 can move in the second direction through the groove opening 1234 to detach from the mounting base 122, making it easier to remove the connecting part 32 from the mounting base 122.

[0070] For example, during the process of removing the connector 32 from the mounting base 122, the plug section 322 can be pressed first to make the plug section 322 elastically deform, and then the connector 32 can be moved in the second direction toward the disassembly notch 1235 so that the plug section passes over the disassembly notch 1235 and is removed from the mounting base 122.

[0071] Reference Figure 5 According to some embodiments of this utility model, in the third direction, the maximum size of the locking hole 1232 is d1, and the length of the connection position between the disassembly notch 1235 and the slot opening 1234 is d3, where d1 > d3, and the first direction, the second direction, and the third direction intersect each other. By making the maximum size d1 of the locking hole 1232 greater than the length d3 of the connection position between the disassembly notch 1235 and the slot opening 1234, the locking connection between the connecting part 32 and the locking hole 1232 can be made more sufficient, preventing the connecting part 32 from naturally falling off from the disassembly notch 1235 and causing the connection between the connecting part 32 and the locking hole 1232 to fail, and making the connection between the connecting part 32 and the mounting base 122 more secure.

[0072] Reference Figure 4 and Figure 5 According to some embodiments of the present invention, the size of the disassembly notch 1235 in the third direction is reduced from the locking hole 1232 to the disassembly notch 1235. By reducing the size of the disassembly notch 1235 in the third direction from the locking hole 1232 to the disassembly notch 1235, the sidewall of the disassembly notch 1235 can guide the connecting part 32 during the process of disassembling the connecting part 32 from the mounting base 122 through the disassembly notch 1235, thereby reducing the difficulty of disassembling the connecting part 32 from the mounting base 122.

[0073] Reference Figure 4According to some embodiments of this utility model, the mounting base 122 includes an anti-rotation baffle 1236. The anti-rotation baffle 1236 is located on the side of the snap-fit ​​plate 1231 opposite to the mounting groove 1233, and in a second direction, the anti-rotation baffle 1236 is located on the side of the snap-fit ​​hole 1232 away from the disassembly notch 1235 to restrict the rotation of the wire fastener 30. Since the plug segment 322 has different dimensions in different directions, when the plug segment 322 is inserted into the snap-fit ​​hole 1232, if the plug segment 322 rotates around the first direction, the dimension of the plug segment 322 in the third direction decreases, and the plug segment 322 may naturally detach from the mounting base 122 through the disassembly notch 1235, causing the wire fastener 30 to fail in its fixing effect on the wire harness. By providing an anti-rotation baffle 1236 on the mounting base 122, the anti-rotation baffle 1236 can restrict the rotation of the wire fixing member 30, preventing the wire fixing member 30 from naturally detaching from the mounting base 122 after rotating around the first direction, thus ensuring a more complete snap-fit ​​connection between the wire fixing member 30 and the mounting base 122. By positioning the anti-rotation baffle 1236 on the side of the snap hole 1232 away from the disassembly notch 1235, the anti-rotation baffle 1236 can be prevented from obstructing the disassembly notch 1235, allowing the connecting part 32 to be normally removed through the disassembly notch 1235.

[0074] For example, the connecting base 321 also includes an anti-rotation arm that extends in a third direction. When the connecting part 32 tends to rotate about the first direction, the anti-rotation arm abuts against the anti-rotation baffle 1236 in the second direction, and the anti-rotation baffle 1236 prevents the connecting part 32 from rotating about the first direction, making the snap-fit ​​connection between the connecting part 32 and the mounting base 122 more secure.

[0075] Reference Figure 6 According to some embodiments of this utility model, the wire fixing part 31 is a cable tie structure. By making the wire fixing part 31 a cable tie structure, the connection between the wire fixing part 31 and the wire harness can be made more convenient, the steps for connecting the wire fixing part 31 and the wire harness can be simplified, and the installation efficiency can be improved.

[0076] Reference Figure 6 According to some embodiments of the present invention, the electrical control box assembly 100 further includes a sheath 4, which is sleeved on the outer periphery of the wiring harness and passes through the through hole 311. By including the sheath 4 in the electrical control box assembly 100, the sheath 4 can protect the connecting wiring harness and reduce the risk of short circuits caused by friction or scratches on the connecting wiring harness; by having the sheath 4 pass through the through hole 311, the wire fixing member 30 can simultaneously fix the sheath 4 and the connecting wiring harness, more effectively preventing the connecting wiring harness from tangling or interfering with other components.
