Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, and in particular relates to an air conditioner. Background Technology

[0002] Air conditioners, as an indispensable household appliance in modern life, provide comfortable temperature and humidity regulation for indoor environments. The control board is a key component of the air conditioner. Installed on the indoor unit and / or outdoor unit, the control board centrally manages the air conditioner's operating procedures, logic control, and the processing of various sensor data, ensuring that the air conditioner operates stably and efficiently according to preset modes.

[0003] In the production, maintenance, and quality inspection stages of electronic control boards, high-current testing is a crucial step in ensuring their performance reliability. Traditional high-current testing methods primarily rely on the cleaving method, which involves first cutting a break in the copper wire of the control board, then soldering wires to both sides of the break, and finally using current clamps to hold the wires in place to measure the current parameters. While this method has been used in the industry for a long time and its measurement principle is relatively simple and intuitive, it has many drawbacks in practical operation.

[0004] First, the wire-cutting method causes irreversible damage to the control board. The cutting operation alters the original circuit structure, easily leading to short circuits or open circuits, increasing maintenance costs and reducing product reliability. Second, wire cutting and soldering require significant time and manpower, resulting in low testing efficiency and failing to meet the demands of rapid testing on large-scale production lines. Third, the external wires used in traditional wire cutting methods differ greatly in material and thickness from the copper wires on the control board, leading to a mismatch in thermal conductivity. This makes it difficult to accurately measure the temperature rise of the control board under high current, affecting the accuracy of test data. Furthermore, the mechanical connection method of temporary jumpers has poor stability and is prone to measurement interruptions or data anomalies due to vibration or poor contact. In control boards with high-density wiring, it may even cause secondary damage or short circuit risks. Moreover, it lacks integrated design, is incompatible with surface mount technology (SMT) processes, and is difficult to adapt to automated production processes. Utility Model Content

[0032] This utility model provides an air conditioner 10, as described below. Figures 1-11 The air conditioner 10 provided in this application will be described.

[0033] In one illustrative embodiment of the air conditioner 10 provided by this utility model, refer to Figure 1 The air conditioner 10 may include an indoor unit 1. The indoor unit 1 is usually installed indoors and is used for heat exchange with the indoor environment. The indoor unit 1 may be a wall-mounted type, a floor-standing type, a ducted type, a curtain type, etc.

[0034] Indoor unit 1 may include an indoor unit housing. The indoor unit housing forms the appearance of indoor unit 1.

[0035] The indoor unit casing has an internal mounting cavity. The mounting cavity is used to house and fix various components in the indoor unit 1, which can prevent external objects from colliding with the various components inside the indoor unit casing, thereby improving the reliability of the indoor unit 1 during transportation or installation.

[0036] The indoor unit housing may include an air inlet. The air inlet communicates with the mounting cavity and serves as the entrance for external air to flow into the indoor unit housing, allowing indoor air to enter the mounting cavity through the air inlet.

[0037] The indoor unit casing may include an air outlet. The air outlet is connected to the mounting cavity and serves as the outlet for the heat exchange airflow inside the indoor unit casing, allowing the airflow inside the mounting cavity to flow out through the air outlet.

[0038] The indoor unit 1 may include an indoor heat exchanger 11. The indoor heat exchanger 11 is located inside the indoor unit casing and is used to exchange heat with the airflow inside the indoor unit casing.

[0039] Continue to refer to Figure 1 The air conditioner 10 may include an outdoor unit 2. The outdoor unit 2 is usually installed outdoors and is used to transfer heat from the indoor unit to the outdoor unit. The indoor unit 1 and the outdoor unit 2 may be configured as an integrated unit or a split unit.

[0040] Outdoor unit 2 may include an outdoor unit housing. The outdoor unit housing forms the appearance of outdoor unit 2. The interior of the outdoor unit housing is hollow to form an accommodating space. The accommodating space is configured to accommodate multiple components of outdoor unit 2, such as compressor 22, outdoor fan, outdoor electrical box, etc.

[0041] The outdoor unit housing may include an outdoor air inlet. The outdoor air inlet may be connected to the housing space, serving as the entrance for external air to flow into the housing space.

[0042] The outdoor unit casing may include an outdoor air outlet. The outdoor air outlet may communicate with the housing space and serve as an outlet for airflow from the indoor casing, allowing airflow from the housing space to exit through the outdoor air outlet.

[0043] The outdoor unit 2 may include an outdoor heat exchanger 21, which may be located within the housing space and is used to exchange heat with the outside air.

[0044] In some embodiments of this application, the air conditioner 10 may include a fan located in the indoor unit 1 and the outdoor unit 2.

[0045] Here, the fan located in indoor unit 1 is defined as indoor fan 12, and the fan located in outdoor unit 2 is defined as outdoor fan 23.

[0046] The indoor fan 12 is installed inside the indoor unit casing and is used to drive the air inside the indoor unit casing to flow from the air inlet to the air outlet so as to send the heat-exchanged air into the room.

[0047] The outdoor fan 23 can be installed inside the containment space. The rotation of the outdoor fan 23 causes outdoor air to enter the containment cavity through the outdoor air inlet and exchange heat with the outdoor heat exchanger 21. The outdoor air after heat exchange flows out of the containment cavity through the outdoor air outlet.

[0048] refer to Figure 2 The air conditioner 10 may include a refrigerant circuit 4. A refrigerant circuit 4 is formed by connecting pipes to the indoor unit 1 and the outdoor unit 2 for refrigerant circulation. Through the refrigerant circuit 4, the air conditioner 10 allows the refrigerant to circulate sequentially through the compressor 22, condenser, throttling device, and evaporator, enabling it to perform indoor cooling or heating.

[0049] The refrigerant circuit 4 may include a four-way valve 6 to change the direction of refrigerant flow inside it.

[0050] The air conditioner 10 may include a compressor 22. The compressor 22 is disposed within a housing. The compressor 22 is used to compress refrigerant gas in a low-temperature, low-pressure state into refrigerant gas in a high-temperature, high-pressure state, and discharge the compressed refrigerant gas to the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0051] The air conditioner 10 may include a throttling device for throttling, which is provided in the indoor unit 1 or the outdoor unit 2. The throttling device may be an expansion valve 3, which expands the high-temperature, high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant.

[0052] The evaporator evaporates the refrigerant that expands in the expansion valve and returns the refrigerant gas, now at a low temperature and low pressure, to the compressor 22. The evaporator achieves a cooling effect by utilizing the latent heat of refrigerant evaporation to exchange heat with the material being cooled. Throughout the cycle, the air conditioner 10 can regulate the temperature for the target user.

[0053] Among them, one of the evaporators and the condenser is an indoor heat exchanger 11, and the other is an outdoor heat exchanger 21.

[0054] In some embodiments of this application, the air conditioner 10 may include a controller. The controller is electrically connected to the indoor unit 1 and the outdoor unit 2 to control the operation of the various components inside the air conditioner 10, so that the various components of the air conditioner 10 operate to achieve the various predetermined functions of the air conditioner 10.

[0055] It should be noted that the controller is electrically connected to at least the compressor 22, the fan, and the expansion valve 3 to control their operation.

[0056] The controller refers to a device that can generate operation control signals based on instruction operation codes and timing signals, instructing the air conditioner 10 to execute control commands. For example, in response to a power-on or power-off command issued by a user, the controller can perform an operation related to the object selected by the power-on or power-off command.

[0057] In some embodiments of this application, the controller may include an electronic control board 5. The electronic control board 5 is disposed in the indoor unit 1 and / or the outdoor unit 2.

[0058] The control board installed in the indoor unit 1 is defined as the indoor control board 51, and the control board installed in the outdoor unit is defined as the outdoor control board 52.

[0059] refer to Figure 3 The indoor control board 51 is connected to the outdoor control board 52 so that the data information in the indoor control board 51 can be transmitted to each other, and the overall operation of the air conditioner 10 can be coordinated and managed.

[0060] The indoor electrical control board 51 is electrically connected to the motor controller of the indoor fan 13 at least, and is used to control the operation of the indoor fan 12 at least. The outdoor electrical control board 52 is electrically connected to the motor controller of the outdoor fan 24 and the compressor 22 at least, and is used to control the operation of the outdoor motor 24 and the compressor 22 according to the control commands issued by the indoor electrical control board 51, thereby realizing the control of the outdoor fan 23 and the compressor 22.

[0061] High-current testing is crucial during the production, maintenance, and quality inspection stages of the control board 5. This type of testing requires precise measurement of current parameters in the circuit and evaluation of the temperature rise of conductors under high current to ensure the safety and reliability of the control board 5. In traditional technologies, high-current paths are typically achieved through copper wires on the circuit board, but the testing process requires temporarily disconnecting the wires to connect to the measuring equipment. This places high operational demands on the surface-mount, integrated structure of the control board 5.

[0062] Traditional high-current testing commonly employs the cut-and-cover method, which involves cutting a break in the copper wire of the control board 5, soldering wires to both sides of the break, and then clamping the wires with a current clamp to complete the measurement. This method requires manual operation or specialized equipment to damage the original circuitry of the circuit board, making the process cumbersome and time-consuming. Furthermore, traditional solutions rely on wires, but the specifications, insulation materials, and thicknesses of these components differ significantly from the copper wires on the circuit board, making it difficult to accurately match the thermal conductivity of the control board 5. This renders the solution unsuitable for directly measuring the temperature rise of the control board 5. In addition, temporary jumpers are typically fixed using plug-in or soldering methods, which can lead to poor contact and low installation efficiency, especially in high-density wiring control boards 5, potentially causing secondary damage or short-circuit risks.

[0063] To address the aforementioned technical problems, in some embodiments of this application, the air conditioner 10 may include a shorting patch 7. (Referring to...) Figure 4 The shorting patch 7 is located on the control board 5 to allow the flow of large current.

[0064] In this embodiment, the shorting patch 7 is set to enable the normal flow of high current on the control board 5, providing basic hardware support for the normal operation of the control board 5 and subsequent high current testing, meeting the high current requirements of the air conditioner during operation, and ensuring the normal operation of the air conditioner.

[0065] refer to Figure 5 The shorting patch 7 may include an electrode 73, and two electrodes 73 are configured and soldered to the control board 5 at intervals.

[0066] The two spaced electrodes 73 provide a stable and reliable solder joint for the shorting patch 7, which can firmly fix the shorting patch 7 to the control board 5, ensuring the stability of the electrical connection, and providing basic support for subsequent connection of other components and the conduction and measurement of current.

[0067] refer to Figure 6 The shorting patch 7 may include a connecting part 71, and the two ends of the connecting part 71 in the length direction are electrically connected to two electrodes 73 through two folded parts 72 respectively.

[0068] The two ends of the connecting part 71 are connected to the two electrodes 73 through the two folding parts 72 respectively, forming a complete current conduction path. This ensures that the current can flow smoothly from one electrode 73 through the folding part 72 and the connecting part 71 to the other electrode 73, realizing the stable flow of large current on the shorting patch 7. It also provides a clear measurement position for subsequent current measurement.

[0069] refer to Figure 6 One end of the folded part 72 is connected to the end of the electrode 73 away from the control board 5, and the two ends of the connecting part 71 in the length direction are respectively connected to the other ends of the two folded parts 72.

[0070] The folding part 72 can be unfolded or folded along the thickness direction of the electronic control plate 5 so that the distance between the connecting part 71 and the electronic control plate 5 can be adjusted.

[0071] The folding part 72 enables the shorting patch 7 to have a foldable and adjustable structure, which can flexibly adjust the distance between the connecting part 71 and the control board 5 as needed, creating conditions for convenient current measurement and improving the flexibility and adaptability of the shorting patch 7.

[0072] refer to Figure 8 When the folding part 72 is in the unfolded state, the connecting part 71 can be clamped with a clamp-on ammeter to detect the operating current of the control board 5.

[0073] Specifically, the folding part 72 can be unfolded or folded along the thickness direction of the electronic control plate 5, making the distance between the connecting part 71 and the electronic control plate 5 adjustable. (Reference) Figure 4 , Figure 5 Under normal operating conditions, the folding part 72 can be folded to reduce the distance between the connecting part 71 and the control board 5, allowing the connecting part 71 to be close to the control board 5 and reducing space occupation. When a large current measurement is required, the folding part 72 can be unfolded to increase the distance between the connecting part 71 and the control board 5. At this time, the connecting part 71 is fully exposed, which facilitates the clamping of the clamp ammeter without the need for destructive operation on the control board 5, improving the convenience and efficiency of testing, and effectively protecting the control board 5.

[0074] In this embodiment, by setting a shorting patch 7 including an electrode 73, a folded portion 72 and a connecting portion 71, it is possible to perform high-current testing conveniently and quickly without damaging the circuit of the control board 5, which improves the convenience and efficiency of testing, while avoiding irreversible damage to the circuit board caused by the traditional wire cutting method, and ensuring the integrity and reliability of the control board 5.

[0075] It should be noted that the thickness of the connecting part 71 can be set according to actual needs to meet different requirements.

[0076] In some embodiments of this application, reference is made to Figure 5 , Figure 7 The two ends of the electrode 73 along its length are connected to support members 74.

[0077] The connection of the support 74 provides additional mechanical support and stability for the electrode 73, enhances the connection strength between the electrode 73 and the control board 5, ensures the stability of the shorting patch 7 on the control board 5, and can effectively resist external interference such as electromagnetic force and mechanical vibration generated when current passes through, thereby improving the reliability and service life of the shorting patch 7.

[0078] In this embodiment, a receiving portion is formed between the two support members 74 at both ends of the electrode 73. A folded portion 72 is located within the receiving portion, and the formation of the receiving portion can protect the folded portion 72 to a certain extent.

[0079] In some embodiments, reference Figure 9 A switching part 75 is provided at the connection between the connecting part 71 and the folding part 72. The switching part 75 is interference-fitted with the receiving part so that the folding part 72 is in a folded state.

[0080] In this embodiment, by interfering with the switching part 75 and the receiving part, the folding part 72 can be kept in the folded state, thus realizing the automatic locking function of the folding part 72.

[0081] When current measurement is not required, the interference fit between the two can keep the folded part 72 in the folded state, which increases the stability of the folded part 72 in the folded state, reduces the space occupied by the shorting patch 7 on the control board 5, avoids interference between the connecting part 71 and other components, improves the neatness and reliability of the control board 5, and also provides a convenient switching method for unfolding the folded part 72.

[0082] In some embodiments of this application, reference is made to Figure 9 The top of the support members 74 at both ends of the electrode 73 is provided with a support portion 77. The support portion 77 is located on the mutually facing sides of the two support members 74, and is used to support the switching portion 75 when the folded portion 72 is in the folded state.

[0083] The support portion 77 provides additional support to the switching portion 75. When the folded portion 72 is in the folded state, the support portion 77 provides stable support to the switching portion 75, preventing the switching portion 75 from excessively bending the folded portion 72 during operations such as pressing it to an interference fit with the receiving portion. This ensures the structural stability and integrity of the folded portion 72, extends its service life, and thus ensures the normal use and reliability of the entire shorting patch 7.

[0084] In some embodiments of this application, reference is made to Figure 10 The two ends of the electrode 73 along its length are connected to support members 74. Multiple cable management plates 76 are spaced apart between the two support members 74 corresponding to the electrode 73. The cable management plates 76 are used to support the folded part 72 in the folded state.

[0085] The cable management plate 76 provides good support for the folded part 72 when it is folded, so that the folded part 72 can maintain a stable position and shape, and avoid the folded part 72 from deforming or shaking due to its own weight or external pressure, thereby affecting the performance and reliability of the shorting patch 7.

[0086] Continue to refer to Figure 10 Multiple cable trays 76 are arranged at both ends of the support member 74 along its length to support the folded part 72 in the folded state.

[0087] The arrangement of multiple cable trays 76 also helps to distribute the pressure on the folding part 72 and extend the service life of the folding part 72.

[0088] It should be noted that the length direction of the support member 74 is the same as the length direction of the connecting part 71. That is to say, both the end of the support member 74 near the connecting part 71 and the end away from the connecting part 71 are provided with cable management plates 76.

[0089] In this embodiment, by setting multiple cable management trays 76, the folded part 72 in the folded state is supported, so that the folded part 72 can be placed more flat and stable when folded, reducing the shaking or deformation of the folded part 72 in the folded state. At the same time, the structural strength between the two support members 74 is enhanced.

[0090] In some embodiments of this application, reference continues to be made to Figure 10 The folding part 72 has a plurality of folding units 721 connected in sequence. When the folding part 72 is in the folded state, the cable tray 76 is supported at the bottom of the connection between two adjacent folding units 721.

[0091] In this embodiment, when the folding part 72 is folded, the connection of each folding unit 721 can be fully, accurately and effectively supported, which further enhances the overall stability of the folding part 72, effectively prevents the folding part 72 from folding and deforming in the folded state, and helps to improve the service life of the folding part 72.

[0092] In some embodiments of this application, reference is made to Figure 7 The electrode 73 is connected to two support members 74 at both ends along its length. A switching part 75 is provided at the connection between the connecting part 71 and the folding part 72. The switching part 75 is engaged with the support member 74 through the snap-fit ​​structure 8 so that the folding part 72 is in a folded state.

[0093] It should be noted that when the snap-fit ​​structure 8 is opened, the folding part 72 can extend freely.

[0094] In this embodiment, the locking function of the folded portion 72 is achieved through the snap-fit ​​structure 8. When current measurement is not required, the folded portion 72 can be kept in the folded state, making operation simple and convenient. Simply engaging the snap-fit ​​structure 8 allows for quick folding and locking of the folded portion 72, reducing the space occupied by the shorting patch 7 on the control board 5. Simultaneously, the snap-fit ​​structure 8 also provides a convenient switching method for unfolding the folded portion 72. When measurement is needed, the snap-fit ​​structure 8 can be quickly released to unfold the folded portion 72 for measurement, improving operational convenience and efficiency.

[0095] Continue to refer to Figure 7 In some embodiments, the snap-fit ​​structure 8 may include a slot 81, which is disposed at the top of the support member 74. The slot 81 provides a stable and easily accessible fixing point for the snap-fit ​​structure 8.

[0096] The locking structure 8 may include locking rods 82, which are disposed at both ends along the length of the switching part 75. The locking slots 81 are adapted to engage with the locking rods 82 to keep the folded part 72 in the folded state.

[0097] The locking mechanism between the lever 82 and the slot 81 allows for quick folding and locking of the folding section 72, ensuring its stability in the folded state and preventing it from loosening or accidentally unfolding due to external non-human operation. This improves the convenience and efficiency of the folding operation.

[0098] Of course, in some other embodiments, multiple snap-fit ​​structures can be evenly arranged on the folding portion 72, and the multiple snap-fit ​​structures cooperate to keep the folding portion 72 in the folded state. Wherein, when the snap-fit ​​structure is opened, the folding portion 2 can be freely extended.

[0099] In some embodiments of this application, reference is made to Figure 11The connecting portion 71 may include a conductive unit 711. The conductive unit 711 may be made of copper.

[0100] By setting the conductive unit 711, the stable conduction of large current can be ensured, meeting the current requirements of the control board 5 during normal operation and testing, and ensuring the normal operation of the air conditioner and the accuracy of current measurement.

[0101] The connecting part 71 may include an insulating unit 712, which covers the outer wall of the conductive unit 711, preventing direct contact between the conductive unit 711 and other components, and improving the safety and reliability of the shorting patch 7.

[0102] In this embodiment, the connection part 71 of the above structure not only ensures good conductivity of the connection part 71 to meet the requirements of high current flow, but also protects the conductive unit 711 through the insulating unit 712 to prevent current leakage, improves the safety of the shorting patch 7, and ensures the normal operation of the circuit of the control board 5.

[0103] In some embodiments of this application, the folded portion 72 and the connecting portion 71 have the same specific configuration. That is, the folded portion may include a conductive unit and an insulating unit covering the outer wall of the conductive unit.

[0104] In some embodiments of this application, the switching unit 75 is made of an insulating material.

[0105] The switching unit 75 is made of insulating material, which ensures that it will not conduct electricity during operation and that the current can only flow in the conductive path of the short-circuit patch 7, ensuring the normal operation of the circuit of the control board 5; at the same time, it can also prevent current leakage and ensure the accuracy and reliability of current measurement.

[0106] In some embodiments of this application, the switching part 75 is attached to the connection between the connecting part 71 and the folding part 72. (See reference...) Figure 10 The switching section 75 is rectangular in shape.

[0107] In this embodiment, the switching part 75 is attached without the need for complicated tools or equipment, and the operation is simple and quick, making it convenient for the installation and fixation of the switching part 75 during production and assembly.

[0108] In some embodiments of this application, the folding portion 72 has reciprocating creases along the thickness direction of the electronic control plate 5, so that the distance between the connecting portion 71 and the electronic control plate 5 can be adjusted.

[0109] In this embodiment, by setting the folding part 72 and the connecting part 71, the flow of large current on the control board 5 can be realized and the distance between the connecting part 71 and the control board 5 can be adjusted, which facilitates current detection, solves the drawbacks of the traditional wire cutting method test, improves the convenience and efficiency of the test, and protects the control board 5 from damage, ensuring its reliability and integrity.
