DETAILED DESCRIPTION

[0028] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0029] In the description of the present application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0030] The terms "first", "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0031] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] In the present application, the air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0033] The compressor compresses the refrigerant gas in a low temperature and low pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process.

[0034] The expansion valve expands the high-temperature and high-pressure liquid refrigerant condensed in the condenser into a low-pressure liquid refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. In the entire cycle, the air conditioner can adjust the temperature of the indoor space.

[0035] The outdoor unit of the air conditioner refers to a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and the expansion valve may be provided in the indoor unit or the outdoor unit.

[0036] The indoor heat exchanger and the outdoor heat exchanger function as a condenser or an evaporator. When the indoor heat exchanger functions as a condenser, the air conditioner functions as a heater in a heating mode, and when the indoor heat exchanger functions as an evaporator, the air conditioner functions as a cooler in a cooling mode.

[0037] The air conditioner of the present application may be a split-type air conditioner in which the outdoor unit and the indoor unit are separated, or may be an integrated air conditioner in which the outdoor unit and the indoor unit are integrated into one.

[0038] Reference Figures 1 to 3 According to an embodiment of the present application, the air conditioner includes a housing 10 , a heat exchanger 20 and a fan 30 .

[0039] The housing 10 forms the appearance of the air conditioner and is generally in the shape of a rectangular box. The housing 10 has a front wall 11 forming a front structure, a rear wall 12 forming a rear structure, a top wall 13 forming a top structure, a bottom wall 14 forming a bottom structure, and a left wall 15 and a right wall 16 forming a left and right side structure.

[0040] An opening-shaped main air inlet 121 is formed on the rear wall 12, an opening-shaped side air inlet 151 is formed on the left wall 15, an opening-shaped air outlet is formed on the front wall 11, a grille plate 17 is installed at the air outlet, and the small holes on the grille plate 17 form an air outlet 171. External air enters the housing 10 from the side air inlet 151 and the main air inlet 121, and flows out from the air outlet 171.

[0041] A partition plate 18 is disposed in the housing 10 , and the partition plate 18 is disposed vertically to divide the space in the housing 10 into a fan chamber 191 and a compressor chamber 192 , wherein the fan chamber 191 is located on the left side and the compressor chamber 192 is located on the right side. The air inlet and the air outlet 171 correspond to the fan chamber 191 .

[0042] The heat exchanger 20 is disposed in the fan cavity 191 corresponding to the air inlet and is located on the air movement path from the air inlet to the air outlet 171. The heat exchanger 20 is used to absorb heat from the air introduced into the air inlet or transfer heat to the air.

[0043] The fan 30 is also disposed in the fan cavity 191 for blowing out air so that the air can flow from the air inlet to the air outlet 171. The fan 30 can be fixed by a fan bracket.

[0044] The compressor, gas-liquid separator, solenoid valve, etc. are usually installed in the press chamber 192.

[0045] The air conditioner further includes an electric control box assembly 40, which includes electrical components for realizing the electric control function of the air conditioner. The electric control box assembly 40 can be arranged in the compressor cavity 192, or the electric control box assembly 40 spans the partition plate 18, with the left part thereof being located in the fan cavity 191 and the right part thereof being located in the compressor cavity 192.

[0046] Since the compressor and the like occupy the lower space of the compressor 192 , the electric control box assembly 40 may be disposed in the top space of the housing 10 .

[0047] In addition, the electric control box assembly 40 can be arranged horizontally or placed vertically. When placed horizontally, the height dimension of the electric control box assembly 40 is relatively small, and when placed vertically, the height dimension of the electric control box assembly 40 is relatively large.

[0048] In the following embodiments, the electric control box assembly 40 is arranged horizontally as an example for description:

[0049] Reference Figures 4 to 6The electric control box assembly 40 includes an electric control box 41 and a support plate 42. The electric control box 41 is generally in the shape of a rectangular parallelepiped box, and the support plate 42 is connected to the outside of the electric control box 41.

[0050] The electric control box 41 may include a box body and a box cover. The top of the box body is open, and the box cover is arranged on the top of the box body. The box cover can be opened to disassemble, assemble, repair and other operations on the components inside the box body.

[0051] The support plate 42 is connected to the front of the bottom side of the electric control box 41, so that the components on the support plate 42 can be easily operated from the front side.

[0052] The support plate 42 is used for installing the terminal block 43 and grounding, etc. The terminal block 43 can realize the wiring connection between the outdoor unit and the indoor unit.

[0053] The terminal block 43 can be installed on the front side of the support plate 42, so that wiring can be directly performed on the terminal block 43 from the front, which facilitates the wiring operation during installation and improves the installation efficiency.

[0054] The support plate 42 may include a mounting wall 421, which is parallel to the front wall of the electric control box 41 and is located behind the front wall of the electric control box 41, that is, there is a gap between the mounting wall 421 and the front wall of the electric control box 41. The terminal row 43 is connected to the front end of the mounting wall 421. In the front-to-back direction, the terminal row 43 does not protrude from the electric control box 41; in other words, in the projection of the bottom wall of the electric control box 41, the terminal row 42 is located inside the electric control box 41, so that the terminal row 43 can be prevented from increasing the front-to-back dimension of the electric control box assembly 40.

[0055] The left end of the mounting wall 421 is provided with a first fixed wall 422 extending forward, and the front end of the first fixed wall 422 is connected to the partition plate 18 by screws; the right end of the mounting wall 421 is provided with a second fixed wall 423 extending backward, and the second fixed wall 423 is connected to the right wall 16 of the shell 10 by screws, thereby realizing the connection between the support plate 42 and the shell 10.

[0056] The bottom wall of the electric control box 41 may be provided with a downwardly extending mounting piece 411, and the support plate 42 abuts against the mounting piece 411, and the two may be connected by screws to achieve the installation of the support plate 42 on the electric control box 41. Specifically, there are multiple mounting pieces 411, which respectively achieve the connection between the mounting piece 411 and the mounting wall 421, and the connection between the mounting piece 411 and the second fixed wall 423.

[0057] The electric control box 41 and the support plate 42 can both be made of sheet metal, and the mounting piece 411 is formed by stamping and bending on the sheet metal, that is, the mounting piece 411 and the bottom of the electric control box 41 are formed integrally.

[0058] According to an embodiment of the present application, the electric control box assembly 40 further includes a substrate 44 disposed in the electric control box 41 , and electrical components are connected to the substrate 44 .

[0059] The substrate 44 is placed horizontally; the pins 4326 on the terminal row 43 extend from bottom to top into the electric control box 41 and are welded to the substrate 44. The welding of the pins 4326 of the terminal row 43 and the substrate 44 realizes the board-mounting of the terminal row, improves the integration of the electric control system, and compared with the prior art method in which the terminal row 43 is connected to the substrate 44 through a wire, the board-mounted connection method reduces wiring operations, reduces material costs, and improves manufacturing efficiency.

[0060] Specifically, a first avoidance hole 412 is provided at a position on the electric control box 41 corresponding to the terminal row 43 , and the terminal row 43 passes through the first avoidance hole 412 .

[0061] In some embodiments, the base plate 44 can be installed in the card holder 45, the card holder 45 is in a box shape with an upper end opening, and the base plate 44 can be fixedly connected to the card holder 45 by means of screws and buckles. A second avoidance hole 451 is provided on the card holder 45 at a position corresponding to the first avoidance opening 412.

[0062] In the bottom projection of the electric control box 41, the terminal row 43 is located in the first avoidance hole 412 and the second avoidance hole 451. During assembly, after the terminal row 43 is welded to the substrate 44, the terminal row 43 on the substrate 44 is inserted into the second avoidance hole 451 of the holder 45, and then the substrate 44 is installed in the holder 45, and then the terminal row 43 is inserted into the first avoidance hole 412 of the electric control box 41, and then the holder 45 is installed in the electric control box 41. The terminal row 43 is exposed at the lower end of the electric control box 41, and finally the terminal row 43 is connected to the support plate 42.

[0063] According to the embodiments of the present application, referring to Figures 7 to 12 The terminal block 43 includes an insulating seat 431, a fixing piece 432 and a screw 433. The fixing piece 432 is connected to the insulating seat 431, and the screw 433 is connected to the fixing piece 432.

[0064] The insulating seat 431 is generally block-shaped and has a mounting portion 4311 . The mounting portion 4311 is provided with a through hole 4312 and an anti-slip groove 4313 . The anti-slip groove 4313 is square and penetrates the mounting portion 4311 .

[0065] The fixing sheet 432 is made of metal, and includes a screw-connecting portion 4321 and a supporting leg portion 4322. The screw-connecting portion 4321 is in a sheet shape, and a threaded hole is provided thereon, and the supporting leg portion 4322 is connected to the screw-connecting portion 4321.

[0066] The support leg 4322 is connected to the screw connection portion 4321 at a substantially right angle. The support leg 4322 is inserted into the anti-slip groove 4313, and an anti-slipping tooth 4323 is provided on the support leg 4322. The anti-slipping tooth 4323 is stuck in the anti-slip groove 4313 to prevent the support leg 4322 from slipping out.

[0067] The screw connection portion 4321 covers the front end of the through hole 4312, and the leg portion 4322 is inserted from front to rear into the anti-slip groove 4313. The screw 433 is connected to the screw connection portion 4321 of the fixing plate 432 from front to rear.

[0068] The terminal block 43 further includes a pressing piece 434 , which is passed through the screw 433 and located between the screw cap of the screw 433 and the screw connection portion 4321 .

[0069] According to an embodiment of the present application, the supporting foot portion 4322 may have two upper and lower supporting foot portions 4322 , which are an upper supporting foot portion 4324 connected to the upper end of the screw-connecting portion 4321 and a lower supporting foot portion 4325 connected to the lower end of the screw-connecting portion 4321 .

[0070] The pin 4326 is connected to the rear end of the upper leg portion 4324 and extends upward. The upper end of the pin 4326 is higher than the insulating seat 431 and is used for welding with the substrate 44.

[0071] The fixing sheet 432 is a copper sheet, and the pin 4326, the leg portion 4322 and the screw connection portion 4321 are integrally formed. The fixing sheet 432 is first mounted on the insulating seat 431, and then the free end of the upper leg portion 4324 is bent to form the pin 4326.

[0072] Multiple groups of fixing plates 432 and screws 433 are arranged side by side on the insulating seat 431; multiple groups of fixing plates 432 are arranged left and right. The front end of the mounting portion 4311 is provided with multiple spaced-apart partitions 4314, and the space between the partitions 4314 is a wiring slot 4315, and the screws 433 are connected to the fixing plates 432 from the wiring slot 1315.

[0073] The front end of each fixing piece 432 corresponds to a wiring slot 4315. The lower end of the wiring slot 4315 is open for easy wiring.

[0074] The rear end of the mounting portion 4311 is provided with a plurality of spaced-apart portions 4316, the space between the spacers 4316 is a pin slot 4317, the upper end of the pin slot 4317 is open, and the pin 4326 extends from the bottom to the top of the insulating seat 431 along the pin slot 4317. The rear end and the upper end of the pin slot 4317 are open.

[0075] In some embodiments, the insulating seat 431 includes an insulating body 4318 and a protective portion 4319. The insulating body 4318 is connected to a fixing sheet 432, and the protective portion 4319 is connected to the upper end of the insulating body 4318.

[0076] The top end of the protection part 4319 is extended upward, and the protection part 4319 is at least located at the front side of the pin 4326. Specifically, the protection part 4319 is arranged around the left side, the front side and the right side of the pin 4326.

[0077] The protection part 4319 includes a main protection part located at the front side and side protection parts located at the left and right sides, and the main protection part and the side protection parts form a "U" shape. The lower end portion of the pin 4326 is located in the pin groove 4317, the middle portion of the pin 4326 is surrounded by the protection part 4319, and the upper end portion of the pin 4326 is welded to the substrate 44.

[0078] The protection portion 4319 shields the pins 4326 from the front and the left and right sides, and the support plate 42 shields the pins 4326 from the rear side.

[0079] The protection portion 4319 provides electrical protection for the exposed portion of the pin 4326, thereby avoiding the risk of electric shock caused by touching the exposed pin 4326 during disassembly and assembly operations.

[0080] The thickness of the protection part 4319 is smaller than the thickness of the insulating body 4318 , and the protection part 4319 is close to the pin 4326 . When the electric control box assembly 40 is assembled, the protection part 4319 extends into the second avoidance hole 451 and the first avoidance hole 412 .

[0081] The thickness of the protection part 4319 is relatively small, which can save the manufacturing material of the insulating seat 431; the space occupied by the protection part 4319 is relatively small, which can reserve sufficient positioning space for the detection tooling.

[0082] Specifically, a recessed positioning groove 4310 is provided on the top surface of the insulating body 4318 (the front side of the protective portion 4319 ) and the side surface of the insulating body 4318 for cooperating with the detection tooling to facilitate the detection requirements of the terminal block 43 .

[0083] In the present application, the pins on the terminal block 43 extend into the electric control box 41 and are welded to the substrate 44, so that the terminal block 43 is mounted on the board, which improves the integration of the electric control system. Compared with the method in the prior art in which the terminal block 43 is connected to the substrate 44 through wires, the board-mounted connection method reduces wiring operations, reduces material costs, and improves manufacturing efficiency. While achieving board-mounted connection, the terminal block 43 is installed on the outside of the electric control box 41. There is no need to open the electric control box, and wiring can be directly connected to the terminal block 43.

[0084] In the present application, the card holder 45 is provided with a second avoidance hole 451 , and the electric control box 41 is provided with a first avoidance hole 412 . During assembly, the terminal block 43 can pass through the second avoidance hole 451 and the first avoidance hole 412 , which facilitates the assembly of the terminal block 43 .

[0085] In the present application, the pin 4326 is formed by bending the support leg 4322. During the assembly process, after the fixing plate 432 is installed on the insulating seat 431, the support leg 4326 is vertically bent to form the pin 4326, which can simplify the connection structure between the fixing plate 432 and the insulating seat 431.

[0086] In the present application, a protective portion 4319 for shielding the pins 4326 is provided on the terminal block 43. In the assembled state, the protective portion 4319 is located corresponding to the avoidance hole, which can form electrical protection for the exposed pins 4326 in the avoidance hole, avoiding the risk of electric shock caused by touching the exposed pins 4326 during disassembly and assembly operations.

[0087] In the present application, the thickness of the protective part 4319 is relatively small, which can save the manufacturing materials of the insulating seat 431; the protective part 4319 occupies a relatively small space, which can reserve sufficient positioning space for the detection tooling.
