Description

Technical Field

[0001] The present application relates to the technical field of air conditioning, and in particular to a top-outlet air conditioning outdoor unit. Background Art

[0002] The electric control board is an important component for controlling the operation of the outdoor unit of the air conditioner. The electric control board is usually installed in the electric control box. Since the electric control board will inevitably generate heat when working, the electric control box is usually provided with a radiator, at least part of which is arranged in the electric control box. The radiator effectively dissipates the heat generated by the electric control board through conduction, convection and radiation, ensuring that the temperature of the electric control board is controlled within the normal range, thereby ensuring the stable operation of the electric control board and extending its service life.

[0003] In the outdoor unit of the top-outlet air-conditioning system, the electric control box is usually located outside the casing. The electric control box is usually designed to be relatively sealed, and the air flow effect inside and outside the electric control box is poor. The radiator usually uses conduction or radiation as the main heat dissipation method. However, in the outdoor unit of the top-outlet air-conditioning system, the part of the radiator located outside the electric control box extends into the casing, and the air inside the casing is usually heat-exchanged with the outdoor heat exchanger. When the outdoor heat exchanger works as a condenser, the air temperature inside the casing is relatively high, and the heat dissipation effect of the radiator is difficult to meet the heat dissipation requirements of the outdoor unit of the top-outlet air-conditioning system, resulting in heat accumulation in the electric control box, which is prone to safety hazards.

[0087] The top-outlet air-conditioning outdoor unit provided in the present application may have various implementation forms. Figure 1-Figure 27 It is a specific implementation of the top-outlet air-conditioning outdoor unit of the present application.

[0088] like Figure 1 As shown, the top-outlet air-conditioning outdoor unit provided in the present application includes a casing 100, and the casing 100 is used to form the overall appearance of the air-conditioning outdoor unit; the top of the casing 100 and the bottom of the casing 100 are opposite ends, and the height direction of the casing 100 is from the bottom of the casing 100 to the top of the casing 100; the left side of the casing 100 and the right side of the casing 100 are opposite sides, and the length direction of the casing 100 is from the left side of the casing 100 to the right side of the casing 100; the front side of the casing 100 and the rear side of the casing 100 are opposite sides, and the thickness direction of the casing 100 is from the front side of the casing 100 to the rear side of the casing 100.

[0089] In actual applications, the top-outlet air-conditioning outdoor unit is usually placed on the ground or a support frame, and the bottom surface of the air-conditioning outdoor unit is usually in contact with a supporting surface such as the ground or the support frame.

[0090] The casing 100 includes a casing air outlet 101 . The casing air outlet 101 is disposed at the top of the casing 100 . The air inside the casing 100 is output to the outside through the casing air outlet 101 .

[0091] In some embodiments, the opening of the housing air outlet 101 is usually arranged to face upward.

[0092] The housing 100 includes a housing air inlet 102 . The housing air inlet 102 is disposed at the outer periphery of the housing 100 . Air outside the housing 100 enters the interior of the housing 100 through the housing air inlet 102 .

[0093] In some embodiments, the opening direction of the casing air inlet 102 is arranged to intersect with the opening direction of the casing air outlet 101 .

[0094] like Figure 1 and Figure 2 As shown, the housing 100 includes a top cover 110 , which is located at the top of the housing 100 , and a housing air outlet 101 is opened in the top cover 110 .

[0095] In some embodiments, the opening of the casing air outlet 101 is circular, and the casing air outlet 101 is disposed in the middle portion of the top cover 110 .

[0096] like Figure 1-Figure 3 , Figure 5 As shown, the housing 100 includes a side panel 120 , which is located at the periphery of the housing 100 and is used to form a side wall of the housing 100 ; the side panel 120 is connected to the top cover 110 , and the housing air inlet 102 is opened on the side panel 120 .

[0097] like Figure 1 and Figure 6 As shown, the housing 100 includes a bottom plate 130, the bottom plate 130 and the top cover 110 are arranged correspondingly along the height direction of the housing 100, the bottom plate 130 is connected to the side plate 120, and the bottom plate 130, the side plate 120 and the top cover 110 jointly define a receiving cavity. The receiving cavity is used to receive components such as an outdoor heat exchanger 500, a compressor 600 and a heat exchange fan 400 arranged inside the housing 100; wherein the housing air inlet 102 and the housing air outlet 101 are respectively connected to the receiving cavity.

[0098] In some embodiments, the bottom plate 130 is a rectangular structure with cut corners, and the housing 100 is a substantially cubic structure.

[0099] The chassis 130 includes a chassis body, which is connected to the side plate 120 . The chassis body is used to form the bottom surface of the accommodating cavity so as to install, support or protect the components in the accommodating cavity.

[0100] In some embodiments, the chassis body is a sheet metal part, so that the chassis 130 has a higher strength and can also reduce the production cost of the chassis 130.

[0101] like Figure 5 As shown, the top-outlet air-conditioning outdoor unit includes an outdoor heat exchanger 500 , which is disposed in the accommodating cavity for exchanging heat with the air passing therethrough; the outdoor heat exchanger 500 is disposed close to the air inlet 102 of the casing, and the outdoor heat exchanger 500 is installed on the chassis 130 .

[0102] like Figure 6As shown, the top-outlet air-conditioning outdoor unit includes a compressor 600, which is disposed in the accommodating chamber and mounted on the chassis 130. The compressor 600 is used to compress the refrigerant in a low-temperature and low-pressure state into a high-temperature and high-pressure state. The compressor 600, the outdoor heat exchanger 500 and the indoor heat exchanger together form a refrigerant circulation loop, and the refrigerant flows in the refrigerant circulation loop to achieve cooling or heating of the indoor environment by the air conditioner.

[0103] The compressor 600 is arranged in the middle part of the chassis 130, and the outdoor heat exchanger 500 is arranged at the outer edge part of the chassis 130. The outdoor heat exchanger 500 is arranged around the outer periphery of the compressor 600. On the one hand, the area of ​​the outdoor heat exchanger 500 can be increased, and the heat exchange effect of the outdoor heat exchanger 500 can be increased; on the other hand, the outdoor heat exchanger 500 can be arranged close to the air inlet 102 of the casing, so that the air entering the casing 100 can contact the outdoor heat exchanger 500 in time, thereby increasing the heat exchange effect of the outdoor heat exchanger 500.

[0104] like Figure 6 As shown, the chassis 130 includes a first protrusion 131 . The first protrusion 131 is arranged to protrude from the upper surface of the chassis body. The first protrusion 131 is used to install the compressor 600 .

[0105] The first protrusion 131 is located at the middle portion of the chassis body, so that the compressor 600 is installed at the middle portion of the chassis 130 , thereby allowing the compressor 600 to be located in the accommodating cavity.

[0106] In some embodiments, the first protrusion 131 is formed by stamping a sheet metal part. Producing the first protrusion 131 by stamping can not only simplify the production process of the first protrusion 131, but also facilitate production and reduce production costs.

[0107] The first protrusion 131 is provided with a mounting portion 134 , and the mounting portion 134 is connected to the compressor 600 so that the compressor 600 is mounted on the first protrusion 131 .

[0108] In some embodiments, the mounting portion 134 is provided with a buffer 135, and the buffer is used to provide buffering between the compressor 600 and the chassis body. When the chassis 130 is subjected to impact force, the buffer 135 can ensure that the compressor 600 will not be in danger of tilting or falling.

[0109] like Figure 6 As shown, the first protrusion 131 is provided with a recessed portion 1311, and the bottom of the compressor 600 is arranged corresponding to the recessed portion 1311. The recessed portion 1311 is used to increase the distance between the bottom of the compressor 600 and the chassis body along the height direction of the casing 100 to prevent the bottom of the compressor 600 from hitting the chassis body when impacted, and at the same time, the strength of the first protrusion 131 is further increased.

[0110] like Figure 6 As shown, the chassis 130 includes a second protrusion 132 , and the second protrusion 132 is arranged to protrude from the upper surface of the chassis body and is used to install the outdoor heat exchanger 500 .

[0111] The second protrusion 132 and the first protrusion 131 are provided independently of each other to prevent the weight of the outdoor heat exchanger 500 from being transferred to the first protrusion 131 and the weight of the compressor 600 from being transferred to the second protrusion 132 .

[0112] Since the air conditioner outdoor unit is arranged outdoors and the air outlet 101 of the casing is arranged upward, water droplets are easily dropped from the air outlet 101 of the casing onto the bottom plate 130. In order to prevent water droplets from accumulating on the bottom plate 130 and affecting the operation of other components of the outdoor unit, the bottom plate 130 is provided with a second drainage portion 136 so that the water droplets dropped on the bottom plate 130 can be discharged from the accommodation cavity by the second drainage portion 136.

[0113] The bottom plate 130 includes a drainage portion 133 , which is located between the first protrusion 131 and the second protrusion 132 . The drainage portion 133 is defined by the first protrusion 131 and the second protrusion 132 and is used to collect water drops falling on the bottom plate 130 .

[0114] The recessed portion 1311 is connected to the drainage portion 133 . The bottom height of the recessed portion 1311 is higher than or equal to the bottom height of the drainage portion 133 , so that water drops in the recessed portion 1311 can be gathered into the drainage portion 133 .

[0115] The drainage portion 133 is provided with a second drainage portion 136 , so that water drops in the drainage portion 133 can flow to the outside of the housing 100 through the second drainage portion 136 .

[0116] like Figure 3 As shown, the top-outlet air conditioner outdoor unit includes a heat exchange fan 400, which is located in the accommodating cavity and is arranged near the housing air outlet 101. Through the operation of the heat exchange fan 400, outdoor air enters the accommodating cavity through the housing air inlet 102, contacts the outdoor heat exchanger 500, and is output to the outdoors through the housing air outlet 101.

[0117] In a top-outlet air-conditioning outdoor unit, the heat exchange fan 400 is usually an axial flow fan, and the heat exchange fan 400 and the casing air outlet 101 are arranged correspondingly along the height direction of the casing 100 .

[0118] In some embodiments, the heat exchange fan 400 is located above the compressor 600 , and the heat exchange fan 400 is located below the air outlet 101 of the casing.

[0119] The heat exchange fan 400 includes fan blades, and the fan blades are used to promote air flow.

[0120] The heat exchange fan 400 includes a motor, and the fan blades are connected to the output shaft of the motor. The motor is located below the top cover 110, and the output shaft of the motor is arranged downward. The motor is used to drive the fan blades to rotate.

[0121] like Figure 4 As shown, the top cover 110 is connected to an air guide ring 111, which is arranged at the air outlet 101 of the casing, and at least a portion of the air guide ring 111 extends from the air outlet 101 of the casing into the accommodating cavity; the interior of the air guide ring 111 defines a through cavity extending along the height direction of the casing 100, and at least a portion of the heat exchange fan 400 is located in the through cavity. The air guide ring 111 is used to guide the air flow in the accommodating cavity so that the heat exchange fan 400 can better play the role of inducing air.

[0122] A reinforcing rib 1111 is provided on the outer periphery of the air guide ring 111 . The reinforcing rib 1111 is arranged protruding from the outer surface of the air guide ring 111 . The reinforcing rib 1111 is used to increase the strength of the air guide ring 111 .

[0123] In some embodiments, the reinforcing ribs 1111 are ring-shaped along the outer circumference of the air guide ring 111 .

[0124] like Figure 1 As shown, the top-outlet air-conditioning outdoor unit includes a fan cover 200, which is disposed at the air outlet 101 of the housing and connected to the top cover 110. The fan cover 200 is used to provide protection for the heat exchange fan 400 and the fan blades to prevent damage to the fan or accidental injury caused by inhalation of indoor debris. The fan cover 200 can also concentrate and evenly guide the wind flow, making the air flow blown out by the fan more concentrated and even.

[0125] In some embodiments, the motor is connected to the fan cover 200 so that the heat exchange fan 400 is disposed in the accommodating cavity.

[0126] like Figure 1 and Figure 3 As shown, the top-outlet air-conditioning outdoor unit includes an electric control box 300 , which is installed on the casing 100 and located outside the accommodating cavity.

[0127] like Figure 7 and Figure 8 As shown, an electric control board 330 is provided in the electric control box 300. The electric control board 330 is provided with a number of electrical components to control the operation of the air conditioner outdoor unit. This belongs to the prior art in the field and will not be described in detail.

[0128] In some embodiments, the length direction of the electric control board 330 is generally arranged along the height direction of the housing 100 to facilitate the arrangement of the electric control board 330 and reduce the space occupied by the electric control board 330 in the horizontal direction.

[0129] like Figure 3As shown, the electric control box 300 includes an electric control box cover 310, which is located outside the accommodating cavity. The electric control box cover 310 and at least part of the side wall of the accommodating cavity are arranged correspondingly in the horizontal direction. The electric control box cover 310 and the side wall of the accommodating cavity together define an installation cavity, and the electric control board 330 and the terminal row are respectively arranged in the installation cavity.

[0130] The electric control box cover 310 is located above the bottom plate 130 , and there is a certain distance between the electric control box cover 310 and the bottom plate 130 along the height direction of the housing 100 ; the electric control box cover 310 is arranged close to the bottom plate 130 at an angle.

[0131] In some embodiments, the electric control box cover 310 is connected to the top cover 110 by fasteners. On the one hand, the top cover 110 imposes constraints on the electric control box cover 310 to increase the firmness of the connection of the electric control box 300. On the other hand, the top cover 110 can seal the top of the installation cavity.

[0132] It should be noted that, for the convenience of description, in this embodiment, the side wall of the accommodating cavity corresponding to the electric control box cover 310 is called a partition 320. The partition 320 is used not only to form the side wall of the accommodating cavity, but also to form the side wall of the installation cavity, that is, the partition 320 is used to separate the accommodating cavity from the installation cavity.

[0133] It should be noted that, since the side walls of the accommodating cavity are mostly formed by the side plates 120 , the partition plate 320 can be considered as a part of the side plates 120 , or can be considered as a component independent of the side plates 120 .

[0134] In some embodiments, the side panel 120 is provided with a notch, the partition 320 is located at the notch, the partition 320 is interconnected with the side panel 120 on both sides along the height direction of the casing 100, the lower end of the partition 320 is connected to the chassis 130, the partition 320 and the side panel 120 as well as the top cover 110 and the chassis 130 together define a accommodating cavity; the partition 320 and the electric control box cover 310 together define an installation cavity.

[0135] The electric control board 330 is installed on a side of the partition plate 320 facing the installation cavity.

[0136] like Figure 7-Figure 8 , Figure 10-11 As shown, the electric control box 300 includes a bottom plate 350, which is arranged at the bottom of the electric control box cover 310. The bottom plate 350 and the top cover 110 are arranged correspondingly along the height direction of the casing 100, so that the bottom plate 350 forms the bottom surface of the installation cavity and blocks the bottom of the installation cavity.

[0137] like Fig.12As shown, the bottom plate 350 is provided with a bottom plate bending portion 351, which is located at one end of the bottom plate 350 close to the partition 320. The bottom plate bending portion 351 is used to increase the contact area between the bottom plate 350 and the partition 320, thereby increasing the firmness of the connection between the bottom plate 350 and the partition 320.

[0138] In some embodiments, the bottom plate 350 is welded to the partition plate 320 .

[0139] In practical applications, the partition plate 320 and the side plate 120 usually need to be powder-sprayed. In other embodiments, the bottom plate 350 is welded to the partition plate 320 and then powder-sprayed together with the partition plate 320 .

[0140] It should be noted that the side of the bottom plate 350 away from the partition plate 320 abuts against the electric control box cover 310 to avoid a large gap between the bottom plate 350 and the electric control box cover 310 .

[0141] like Fig.17 , Fig.18 and Fig.24 As shown, the electric control box 300 includes a radiator 390 , which passes through the partition 320 and is disposed in the accommodating cavity. The radiator 390 passes through the electric control board 330 to dissipate heat for the electric control board 330 .

[0142] Since the radiator 390 is arranged in the accommodating cavity through the partition 320, and the air in the accommodating cavity is heat-exchanged by the outdoor heat exchanger 500, when the outdoor heat exchanger 500 works as a condenser, the air in the accommodating cavity is hot air, which will reduce the heat dissipation effect of the radiator 390. If the heat generated by the electronic control board 330 is not dissipated in time, it is easy to accumulate in the installation cavity, causing safety hazards.

[0143] The electric control box 300 is provided with a heat dissipation air inlet 302, which is connected to the installation cavity, and outdoor air enters the installation cavity through the heat dissipation air inlet 302; the electric control box 300 is provided with a heat dissipation air outlet 301, so that the air in the installation cavity is output from the installation cavity through the heat dissipation air outlet 301.

[0144] The heat exchange fan 400 operates to introduce outdoor air into the installation cavity through the heat dissipation air inlet portion 302 and, after heat exchange with the electric control board 330 , the air is output from the installation cavity through the heat dissipation air outlet portion 301 . The air takes away the heat generated by the operation of the electric control board 330 , thereby dissipating the heat of the electric control board 330 .

[0145] It should be noted that the temperature of air after passing through the electric control board 330 is usually higher than the temperature of air not passing through the electric control board 330, and the density of hot air is small. Therefore, according to air thermodynamics, setting the heat dissipation air inlet 302 lower than the setting position of the heat dissipation air outlet 301 can make the air flow better.

[0146] In order to increase the air flow speed in the installation cavity and enhance the heat dissipation effect of the air on the electric control box 300, the heat dissipation air outlet 301 is connected to the accommodating cavity so that the air in the installation cavity can flow faster with the help of the heat exchange fan 400.

[0147] like Fig. 9 As shown, by operating the heat exchange fan 400, air is introduced into the installation cavity through the heat dissipation air inlet portion 302 to contact with the electric control board 330 for heat exchange, and then enters the accommodating cavity through the heat dissipation air outlet portion 301 and is finally output to the outside of the casing 100 through the casing outlet 101.

[0148] It should be noted that connecting the heat dissipation air inlet 302 with the accommodating cavity and allowing air to circulate in and out of the installation cavity with the help of a heat exchange fan 400 will increase the air flow efficiency, which can not only increase the heat dissipation efficiency of the air to the electronic control board 330, but also increase the convection heat dissipation efficiency between the radiator 390 and the air.

[0149] Since the electric control box 300 is arranged outside the accommodation cavity, rain or dust may enter the installation cavity through the heat dissipation air inlet portion 302 and / or the heat dissipation air outlet portion 301, affecting the normal operation of the electric control board 330 and / or the terminal block.

[0150] Based on this, Fig.12 As shown, the heat dissipation air inlet portion 302 is opened on the bottom plate 350 , so that the opening of the heat dissipation air inlet portion 302 is arranged downward to prevent dust or water droplets from entering the installation cavity through the heat dissipation air inlet portion 302 .

[0151] like Fig.13 As shown, the heat dissipation air outlet portion 301 is opened on the partition 320, and the heat dissipation air outlet portion 301 is arranged close to the top of the partition 320 to prevent dust or water droplets from entering the installation cavity through the heat dissipation air outlet portion 301.

[0152] In some embodiments, the heat dissipation air inlet portion 302 is a long hole.

[0153] In some embodiments, a plurality of heat dissipation air inlets 302 are provided, and the plurality of heat dissipation air inlets 302 are distributed in the same plane from a side of the bottom plate 350 close to the electric control box cover 310 toward a side of the bottom plate 350 close to the partition 320 .

[0154] Although the opening of the heat dissipation air outlet 301 is arranged downward, it can prevent rainwater or dust from directly entering the installation cavity through the heat dissipation air inlet 302 to a certain extent. However, since the electric control box 300 is arranged above the cut corner of the chassis 130, there is a distance between the bottom plate 350 and the chassis 130 along the height direction of the casing 100. Rainwater can easily splash back into the installation cavity through the heat dissipation air inlet 302, affecting the normal operation of the electric control board 330.

[0155] To solve this problem, Fig.11As shown, the electric control box 300 includes a first baffle 360, which is arranged below the bottom plate 350. The first baffle 360 ​​is arranged along the height direction of the housing 100 corresponding to the heat dissipation air inlet 302 to prevent rainwater from splashing back into the installation cavity from the heat dissipation air inlet 302.

[0156] The first baffle 360 ​​and the bottom plate 350 together define an air inlet duct, which is connected to the heat dissipation air inlet portion 302. The opening of the air inlet duct is arranged roughly in a horizontal direction, thereby preventing water droplets dripping on the chassis 130 from splashing back into the installation cavity through the heat dissipation air inlet portion 302.

[0157] like Fig.14 As shown, the first baffle 360 ​​is connected to the electric control box cover 310, which can not only realize the installation and fixation of the first baffle 360, but also increase the strength of the electric control box cover 310 to prevent the electric control box cover 310 from deforming outward.

[0158] A box cover bending portion 311 is provided at the bottom of the electric control box cover 310 , and the box cover bending portion 311 is provided on a side of the electric control box cover 310 facing the installation cavity, and the box cover bending portion 311 and a side of the first baffle 360 ​​facing away from the bottom plate 350 are in contact with and connected to each other.

[0159] The first baffle plate 360 ​​is provided with a baffle plate bent portion 361 , and the baffle plate bent portion 361 is in contact with a side of the electric control box cover 310 facing the installation cavity, so as to increase the contact area between the first baffle plate 360 ​​and the electric control box cover 310 .

[0160] The heat dissipation air inlet 302 is opened on the bottom plate 350 , and a first baffle 360 ​​is provided below the bottom plate 350 . The heat dissipation air outlet 301 is shielded by the first baffle 360 ​​to prevent rainwater from splashing back into the electric control box 300 from the heat dissipation air inlet 302 .

[0161] When water droplets splash back into the installation cavity from the heat dissipation air inlet 302, some water droplets may leave the installation cavity from the heat dissipation air inlet 302 under the action of gravity, and some water droplets may drip onto the bottom plate 350. In order to prevent water droplets from splashing back into the installation cavity and accumulating in the installation cavity, as shown in FIG. Fig.13 As shown, the partition 320 is provided with a first drainage portion 303, and the opening direction of the first drainage portion 303 is arranged to intersect with the opening direction of the heat dissipation air inlet portion 302. The first drainage portion 303 is arranged close to the bottom plate 350 so that water droplets splashed back into the accommodating cavity by the heat dissipation air inlet portion 302 can be discharged from the installation cavity by the first drainage portion 303.

[0162] The bottom plate 350 is tilted downward in the horizontal direction close to the partition 320 , so that water drops falling on the bottom plate 350 can be gathered at the connection between the bottom plate 350 and the partition 320 .

[0163] In some embodiments, the bottom plate 350 is tilted downward at an angle less than or equal to 5°. If the bottom plate 350 is tilted too much, the volume of the installation cavity will be wasted, and if the bottom plate 350 is tilted too little, the water droplet convergence effect will be poor.

[0164] The first drainage portion 303 is disposed at the connection between the bottom plate 350 and the partition plate 320 , so that water drops gathered at the connection between the bottom plate 350 and the partition plate 320 are discharged from the installation cavity through the first drainage portion 303 .

[0165] like Fig.15 and Fig.16 As shown, the first drainage portion 303 is connected to the accommodating cavity. Water drops flow into the accommodating cavity from the first drainage portion 303 and drip onto the bottom plate 130 and gather into the drainage portion 133 , and finally are discharged to the outside of the housing 100 by the second drainage portion 136 provided in the drainage portion 133 .

[0166] By connecting the first drainage portion 303 with the accommodating cavity, it is possible to ensure that water droplets in the installation cavity can be discharged in time, and to prevent rainwater or dust from entering the installation cavity through the first drainage portion 303 .

[0167] The electric control box 300 is provided with a terminal block, which is connected to the electric control board 330 to achieve signal transmission. The terminal block is also called a wiring terminal or a wiring block, which is an electrical component used to connect and arrange wires and cables. Its main function is to connect multiple wires to a terminal to achieve circuit connection and power distribution. The terminal block is usually composed of a guide rail with multiple metal terminals and screws, which are used to clamp the wires to ensure that the current can be smoothly transmitted through the terminal block. This is common knowledge in the art and will not be repeated.

[0168] It should be noted that the terminal block also generates heat when working. The heat in the electric control box 300 includes the heat generated by the working electrical components on the electric control board 330 and the heat generated by the terminals when working.

[0169] The terminal block is disposed close to the heat dissipation air inlet portion 302 so that the heat generated when the terminal block is working can be dissipated in time.

[0170] The terminal block is located below the electric control board 330 , which not only facilitates line connection, but also saves horizontal space occupied by the terminal block and the electric control board 330 , and facilitates the arrangement of the terminal block and the electric control board 330 inside the electric control box 300 .

[0171] like Figure 7-Figure 8 and Fig.10As shown, the electric control box 300 includes a support plate 340, and the support plate 340 is used to place the terminal row. Since the terminal row is located below the electric control board 330, the support plate 340 is also located below the electric control board 330. The support plate 340 is arranged close to the bottom plate 350, and there is a certain distance between the support plate 340 and the bottom plate 350 along the height direction of the housing 100 to prevent the support plate 340 from blocking the heat dissipation air inlet 302, thereby blocking the air from the heat dissipation air inlet 302 entering the installation cavity.

[0172] It should be noted that since the terminal row is arranged close to the heat dissipation air inlet portion 302, water droplets splashed back into the installation cavity by the heat dissipation air inlet portion 302 can easily affect the normal operation of the terminal row. By arranging a support plate 340 to install the terminal row, the support plate 340 can block the water droplets and prevent the water droplets splashed back into the installation cavity by the heat dissipation air inlet portion 302 from contacting the terminal row.

[0173] The support plate 340 and the bottom plate 350 together define a connecting air duct, and air flows from the heat dissipation air inlet portion 302 through the connecting air duct into the installation cavity.

[0174] Terminal blocks are usually placed horizontally to reduce the bending of wires and ensure the stability and safety of the connecting cables. However, horizontal placement will increase the horizontal space occupied by the terminal block, while vertical placement may require operators to stand or bend when wiring, which may increase the difficulty and inconvenience of wiring. Moreover, if the vertically placed terminal block is not firmly fixed or affected by external forces, it may shake or tilt. This may not only affect the stability of the wiring, but also pose a potential threat to the overall safety of the air conditioner outdoor unit.

[0175] Based on this, the support plate 340 is limited to form a placement surface, which is an inclined surface inclined downward in the horizontal direction away from the partition 320, so that the terminal row can be placed obliquely in the installation cavity, which not only facilitates the operation of the connector, but also reduces the horizontal space occupied by the terminal row in the installation cavity.

[0176] In some embodiments, the inclination angle of the placement surface is 45°. If the inclination angle of the placement surface is too large, it will be inconvenient to connect the wires, and the support plate 340 has a weak supporting effect on the terminal row, which will reduce the firmness of the connection between the terminal row and the support plate 340; if the inclination angle of the placement surface is too small, the terminal row still occupies a large space in the horizontal direction.

[0177] like Fig.11 As shown, the support plate 340 includes a first support plate 341, and the placement surface is located on the first support plate 341; the first support plate 341 is tilted downward along the height direction of the casing 100 in the direction away from the partition 320. Under the premise that the first support plate 341 occupies a certain space in the horizontal direction of the installation cavity, the support area of ​​the first support plate 341 can be increased.

[0178] The support plate 340 includes a second support plate 342, which is connected to one end of the first support plate 341 that is tilted downward, and the other end of the second support plate 342 is connected to the partition 320. The second support plate 342 and the first support plate 341 are interconnected to form a triangular structure, which can increase the connection strength of the support plate 340.

[0179] The second support plate 342 is arranged along the height direction of the casing 100 corresponding to the heat dissipation air inlet portion 302. The second support plate 342 can block the water droplets splashed back into the installation cavity from the heat dissipation air inlet portion 302 to a certain extent, and reduce the height of the water droplets splashing back into the installation cavity. A part of the water droplets blocked by the second support plate 342 falls to the bottom plate 350, and then gather at the connection between the bottom plate 350 and the partition plate 320 and are discharged by the first drainage portion 303, and the other part falls from the heat dissipation air inlet portion 302 to the first baffle plate 360.

[0180] like Fig.10 As shown, the support plate 340 is connected to the partition 320, and there is a gap between the side of the support plate 340 away from the partition 320 and the electric control box cover 310 in the horizontal direction, so that the air entering the installation cavity from the heat dissipation air inlet portion 302 can circulate in the installation cavity.

[0181] Since the partition 320 is usually powder-coated, and the support plate 340 is usually not powder-coated in order to ensure the normal operation of the terminal block, in actual applications, the support plate 340 is usually connected to the partition 320 through fasteners after the partition 320 is powder-coated.

[0182] At least two fasteners are provided to connect the support plate 340 and the partition 320, so that the support plate 340 and the partition 320 have at least two fixing points, thereby increasing the firmness of the connection between the support plate 340 and the partition 320, and further increasing the reliability of the terminal arrangement placed on the support plate 340.

[0183] like Fig. 20 As shown, the baffle 320 is connected to a baffle 3011, which is arranged at the heat dissipation outlet portion 301, and the baffle 3011 is arranged in the installation cavity. The lower end of the baffle 3011 is connected to the lower edge of the heat dissipation outlet portion 301, and the upper end of the baffle 3011 is inclined upward in a direction away from the baffle 320, so that there is a distance between the upper end of the baffle 3011 and the baffle 320 to prevent the baffle 3011 from closing the heat dissipation outlet portion 301. The baffle 3011 is used to prevent mosquitoes from entering the installation cavity through the heat dissipation outlet portion 301.

[0184] In some embodiments, the heat dissipation air outlet portion 301 is a long hole.

[0185] In some embodiments, a plurality of heat dissipation outlet portions 301 are provided, and the plurality of heat dissipation outlet portions 301 are distributed along the height direction of the housing 100 .

[0186] The opening size of the heat dissipation outlet portion 301 along the height direction of the casing 100 is usually less than or equal to 3 mm. If the opening size of the heat dissipation outlet portion 301 along the height direction of the casing 100 is too large, mosquitoes can easily enter the installation cavity through the heat dissipation outlet portion 301; if the opening size of the heat dissipation outlet portion 301 along the height direction of the casing 100 is too small, the air outlet effect of the heat dissipation outlet portion 301 is poor, and the heat dissipation effect of the electrical control box 300 is poor.

[0187] Since the heat dissipation air outlet 301 is arranged near the top of the partition 320, after the air guide ring 111 extends into the accommodation cavity, part of the air guide ring 111 will be arranged horizontally corresponding to the heat dissipation air outlet 301. There is a certain distance between the air guide ring 111 and the partition 320 in the horizontal direction, which prevents the air guide ring 111 from blocking the heat dissipation air outlet 301 on the one hand, and prevents the air guide ring 111 from colliding and deforming with the partition 320 on the other hand.

[0188] It should be noted that the partial air guide ring 111 and the heat dissipation outlet portion 301 are arranged correspondingly in the horizontal direction, which can prevent rainwater from entering the installation cavity through the heat dissipation outlet portion 301 to a certain extent.

[0189] like Fig. 20 As shown, the interval between the air guide ring 111 and the partition 320 in the horizontal direction is L, and L satisfies the relationship: L≥6mm, L≤22mm. When L is too small, the air guide ring 111 is easy to collide with the partition 320 and deform, and it is not conducive to remove the air guide ring 111 from the accommodating chamber. Since at least part of the heat exchange fan 400 needs to be arranged in the air guide ring 111 so that the air guide ring 111 guides the air to contact the heat exchange fan 400, when L is too large, when the accommodating chamber has the same volume, the selected air guide ring 111 is small in size, and accordingly, the heat exchange fan 400 is also small in size, which makes the air outlet effect of the air conditioner outdoor unit worse.

[0190] When L satisfies the relationship: L≥6mm, L≤22mm, not only can the air guide ring 111 work reliably, but also the specifications of the heat exchanger fan are larger, and the air outlet volume of the air conditioner outdoor unit is large and the air outlet effect is good.

[0191] In practical applications, the air guide ring 111 is curved in shape to better guide the air flow. Therefore, the distance between the same air guide ring 111 and the partition plate 320 along the horizontal direction is not fixed.

[0192] In some embodiments, the minimum distance between the air guide ring 111 and the partition 320 in the horizontal direction is L1, and L1 satisfies the relationship: L1≥6mm, L1≤20mm.

[0193] In some embodiments, the maximum distance between the air guide ring 111 and the partition 320 in the horizontal direction is L2, and L2 satisfies the relationship: L2≥L1+2.

[0194] In some embodiments, the height of the heat exchange fan 400 is generally between 80-150 mm, and the height between the fan blades and the top cover 110 is between 40-100 mm.

[0195] The dimension of the air guide ring 111 along the height direction of the housing 100 is H, and H satisfies the relationship: H≥80mm, H≤180mm.

[0196] When H is too small, the air guiding effect of the air guiding ring 111 is poor; when H is too large, the air guiding ring 111 excessively guides the air, which may easily lead to a decrease in the air output of the heat exchange fan 400.

[0197] Since the air guide ring 111 and the partition 320 are spaced apart in the horizontal direction, the air guide ring 111 and the partition 320 together define an air outlet duct, which is connected to the heat dissipation outlet portion 301. Since the top of the air guide ring 111 is connected to the top cover 110, the top cover 110 blocks the top of the air outlet duct, and the air outlet duct includes an air outlet arranged downward.

[0198] Although the air guide ring 111 and the heat dissipation outlet part 301 are arranged horizontally correspondingly, the air guide ring 111 can block rainwater and prevent rainwater from entering the installation cavity through the heat dissipation outlet part 301, but rainwater may pass through the air outlet of the air duct and then splash into the installation cavity through the heat dissipation outlet part 301.

[0199] In some embodiments, Fig.18 As shown, a second baffle 370 is provided on the side of the partition 320 facing the accommodating cavity. The second baffle 370 is located below the heat dissipation outlet portion 301. The second baffle 370 is used to prevent water droplets from passing through the gap between the air guide ring 111 and the partition 320 and entering the installation cavity from the heat dissipation outlet portion 301.

[0200] like Fig. 22 As shown, the second baffle 370 is provided with at least one baffle 371 arranged in the horizontal direction, and the baffle 371 is used to reduce the distance between the air guide ring 111 and the partition plate 320 in the horizontal direction.

[0201] It should be noted that since the reinforcing ribs 1111 are arranged on the protruding outer surface of the air guide ring 111, the reinforcing ribs 1111 can not only increase the strength of the air guide ring 111 but also reduce the horizontal distance between the air guide ring 111 and the partition 320 to a certain extent, thereby having a certain blocking effect on rainwater.

[0202] The reinforcing ribs 1111 and the baffles 371 are staggered along the height direction of the housing 100 so that the reinforcing ribs 1111 and the baffles 371 can respectively block rainwater to prevent water droplets from passing through the gap between the air guide ring 111 and the partition 320 and entering the installation cavity from the heat dissipation outlet portion 301.

[0203] The reinforcing rib 1111 and the baffle 371 need to have a certain gap along the height direction of the housing 100 so that air can flow into the accommodating cavity through the air outlet duct. The distance between the reinforcing rib 1111 and the baffle 371 along the height direction of the housing 100 is F, and F satisfies the relationship: F ​​≥ 1mm, F ≤ 3mm. If F is too large, the blocking effect of the reinforcing rib 1111 and the baffle 371 on water droplets will be reduced, and if F is too small, abnormal noise will be generated when the air passes through the gap between the reinforcing rib 1111 and the baffle 371.

[0204] In some embodiments, Fig. 22 As shown, there are two baffles 371, and the two baffles 371 are correspondingly arranged along the height direction of the casing 100. There is a certain distance between the two baffles 371 along the height direction of the casing 100. The two baffles 371 are connected to each other through a connecting plate 372 so that the second baffle 370 has a U-shaped structure, and at least one reinforcing rib 1111 is arranged between the two baffles 371 along the height direction of the casing 100.

[0205] like Fig.23 As shown, the dimension of the baffle 371 disposed at the bottom in the first direction is D, the dimension of the reinforcing rib 1111 along the first direction is f, and f and D satisfy the relationship: f+D≥A+2, so that the projections of the reinforcing rib 1111 and the baffle 371 disposed at the bottom in the horizontal direction at least partially overlap, so that the reinforcing rib 1111 and the baffle 371 disposed at the bottom cooperate with each other to prevent rainwater from splashing back from the heat dissipation air outlet 301 into the installation cavity through the gap between the reinforcing rib 1111 and the baffle 371 disposed at the bottom. The first direction is the horizontal direction, and the first direction is the direction from the side of the baffle 371 close to the partition 320 to the side of the baffle 371 away from the partition 320.

[0206] It should be noted that when the projections of the reinforcing rib 1111 and the baffle 371 disposed at the bottom partially overlap in the horizontal direction, the baffle 371 disposed at the bottom will prevent the reinforcing rib 1111 from continuing to move downward. When two baffles 371 are provided, since the reinforcing rib 1111 needs to pass through the baffle 371 disposed at the top along the height direction of the housing 100 and be disposed between the two baffles 371, in order to ensure the reliability of the installation of the air guide ring 111, the projections of the reinforcing rib 1111 and the baffle 371 disposed at the top in the horizontal direction do not overlap, thereby preventing the baffle 371 disposed at the top from interfering with the movement of the reinforcing rib 1111 along the height direction of the housing 100.

[0207] Specifically, the dimension of the upper blocking piece 371 in the first direction is d, f and d satisfy the relationship: f+d≤A-1, and D and d satisfy the relationship: D>d.

[0208] A second baffle plate 370 is disposed below the heat dissipation outlet portion 301 , and the second baffle plate 370 cooperates with the reinforcing ribs 1111 to shield rainwater, thereby preventing rainwater from entering the installation cavity through the heat dissipation outlet portion 301 .

[0209] In other embodiments, Fig.24 As shown, the partition 320 is provided with a third baffle 380, and at least part of the third baffle 380 is arranged at the heat dissipation outlet portion 301. The third baffle 380 is used to reduce the horizontal interval between the partition 320 and the air guide ring 111, thereby preventing rainwater from splashing back into the installation cavity from the heat dissipation outlet portion 301 through the air outlet duct.

[0210] like Fig.26 As shown, the distance between the third baffle 380 and the partition 320 in the horizontal direction is W, and W satisfies the relationship: W ≥ 1mm, W ≤ 3mm. If W is too large, the blocking effect of the third baffle 380 on water droplets will be reduced, and if W is too small, abnormal noise will be generated when air passes through the gap between the partition 320 and the third baffle 380.

[0211] like Fig. 27 As shown, the third baffle 380 is provided with a ventilation portion 381, and the ventilation portion 381 and the heat dissipation outlet portion 301 are staggered along the height direction of the housing 100 to prevent rainwater from entering the installation cavity through the ventilation portion 381 and the heat dissipation outlet portion 301 in sequence. By providing the ventilation portion 381 on the third baffle 380, the blocking effect of the third baffle 380 on the air flowing out of the heat dissipation outlet portion 301 is reduced, so that the air can be discharged from the installation cavity in time.

[0212] like Fig. 27 As shown, a connecting portion 382 is provided on the top of the third baffle 380, and the connecting portion 382 is located in the accommodating cavity. The connecting portion 382 abuts against the top of the partition 320, and the side of the connecting portion 382 facing away from the partition 320 contacts the side of the top cover 110 facing the accommodating cavity. The connecting portion 382 is connected to the top cover 110 through fasteners.

[0213] like Fig. 27 As shown, the third baffle plate 380 is provided with a blocking portion 383, which is arranged on the side of the third baffle plate 380 away from the partition plate 320, and the blocking portion 383 is used to reduce the distance between the third baffle plate 380 and the air guide ring 111 in the horizontal direction, thereby preventing water droplets from passing through the gap between the third baffle plate 380 and the air guide ring 111 and entering the installation cavity through the ventilation portion 381 and the heat dissipation outlet portion 301.

[0214] In some embodiments, the blocking portion 383 is limited to form an arc-shaped matching portion 384 so that the blocking portion 383 is adapted to the shape of the air guide ring 111, thereby better reducing the distance between the third baffle 380 and the air guide ring 111 in the horizontal direction.

[0215] A shock-absorbing sponge is provided on one side of the third baffle plate 380 facing the partition plate 320 , and the shock-absorbing sponge is used to reduce vibration and abnormal noise generated when air flows through the gap between the third baffle plate 380 and the partition plate 320 .

[0216] In some embodiments, the shock-absorbing sponge is adhered to the third baffle 380 .

[0217] In some embodiments, the shock-absorbing sponge is adhered to the top of the third baffle 380 .

[0218] It should be noted that the partition 320 can be provided with a second baffle 370 and a third baffle 380 at the same time, so that the second baffle 370 and the third baffle 380 can block rainwater respectively. The partition 320 can also selectively provide either the second baffle 370 or the third baffle 380 .

[0219] It should also be noted that, in this embodiment, the fasteners are components such as bolts or screws.

[0220] The heat dissipation working principle of the electrical control box 300 in the above-mentioned top-outlet air-conditioning outdoor unit is as follows: by operating the heat exchange fan 400, outdoor air is introduced into the installation cavity through the air inlet duct from the heat dissipation air inlet part 302, and the outdoor air contacts and exchanges heat with the electrical control board 330 and the electrical components on the electrical control board 330, and then enters the accommodating cavity through the air outlet duct from the heat dissipation air outlet part 301, and is finally output from the casing air outlet 101.
