Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and in particular to a top-discharge type outdoor air conditioning unit. Background Technology

[0002] The compressor, indoor heat exchanger, and outdoor heat exchanger are connected by pipes to form a refrigerant circulation loop. The refrigerant circulates within this loop to achieve cooling and heating in the air conditioning system. The refrigerant circulation loop contains components such as four-way valves and solenoid valves. Because these components operate under high-pressure refrigerant circulation and fluctuating temperatures for extended periods, they are prone to damage and may require frequent maintenance or replacement.

[0003] In existing top-discharge air conditioning outdoor units, the electrical box is typically located below the heat exchange fan, next to components such as the compressor and outdoor heat exchanger. This electrical box obstructs the view of components like the four-way valve and solenoid valve. When these components require repair or replacement, technicians must first disassemble the electrical box before repairing or replacing the damaged parts. Because the electrical box contains numerous and complex cables and connectors, disassembling it is difficult, increasing the maintenance complexity of components like the four-way valve and electric expansion valve. Furthermore, messy wiring within the electrical box during repairs can potentially damage the air conditioning system. Utility Model Content

[0004] In view of the shortcomings of the related technologies, this application provides a top-discharge air conditioner outdoor unit by placing the electrical box in front of the heat exchange fan and above the side of the compressor, and providing two independent access ports on the casing, one access port corresponding to the electrical box and the other access port corresponding to the compressor, so that the electrical box and the compressor can be inspected and maintained through their respective access ports.

[0005] This application provides a top-discharge air conditioner outdoor unit, comprising: The casing has an air outlet on the top and an air inlet on the side. The front of the casing has a first inspection port and a second inspection port, which are independently set, with the second inspection port located above the first inspection port. The heat exchanger is located inside the casing, near the air outlet. The outdoor heat exchanger is located inside the casing, with its windward side facing the air inlet and its leeward side facing the inside of the casing. The compressor is located inside the casing and is positioned corresponding to the first maintenance port. The compressor is located on the leeward side of the outdoor heat exchanger and below the heat exchange fan. The electrical box is located inside the housing and corresponds to the second access port. The electrical box is located on the side of the heat exchange fan facing the front of the housing; the electrical box is located on the upper side of the compressor. The front cover, which is detachably connected to the housing, is used to block the first inspection port; The maintenance panel, which is detachably connected to the housing, is used to block the second inspection port.

[0006] In the technical solution, a first inspection port is provided on the front side of the casing, with the compressor positioned corresponding to the first inspection port, allowing the compressor and its connected components to be inspected through the first inspection port; a second inspection port is provided on the front side of the casing, with the electrical box positioned corresponding to the second inspection port, allowing the electrical box to be inspected through the second inspection port; the second inspection port and the first inspection port are set independently, allowing the electrical box and the compressor to be inspected through their respective corresponding inspection ports; the electrical box is located in front of the heat exchange fan and above the side of the compressor to avoid obstructing the compressor and to avoid disassembling the electrical box when inspecting the compressor; a front cover plate is used to seal the first inspection port, and a maintenance panel is used to seal the second inspection port, ensuring the airtightness of the casing.

[0007] In some embodiments of this application, the compressor, the outdoor heat exchanger and the indoor heat exchanger are connected to form a refrigerant circulation loop. A control valve located inside the housing is provided on the refrigerant circulation loop. The control valve is located on the lower side of the electrical box and is set corresponding to the first access port. And / or, a gas-liquid separator is also provided inside the housing. The gas-liquid separator is connected to the inlet end of the compressor through a pipeline. The gas-liquid separator is located on the lower side of the electrical box. The gas-liquid separator is located on the leeward side of the outdoor heat exchanger and is set corresponding to the first maintenance port.

[0008] In the technical solution, components such as the four-way valve, solenoid valve, and gas-liquid separator are placed on the leeward side of the outdoor heat exchanger and below the side of the electrical box, corresponding to the first maintenance port, so that these components can be inspected through the first maintenance port, while avoiding the electrical box from obstructing these components.

[0009] In some embodiments of this application, the electrical box is positioned above the compressor, control valve, and gas-liquid separator on the orthographic projection of the rear side of the housing, and they do not overlap.

[0010] In the technical solution, the electrical box is positioned above the compressor, control valve, and gas-liquid separator on the rear side of the housing, and they do not overlap, so as to avoid the electrical box obstructing the compressor, control valve, or gas-liquid separator in the height direction of the housing.

[0011] In some embodiments of this application, the distance between the front and rear sides of the casing is greater than the distance between the left and right sides of the casing; the two ends of the outdoor heat exchanger along its length are jointly defined by a notch, which is located on the front side of the casing and is corresponding to the first inspection port.

[0012] In the technical solution, by making the distance between the front and rear sides of the casing greater than the distance between the left and right sides of the casing, the size of the front sidewall of the casing is smaller than the size of the left and right sidewalls of the casing, thus allowing the first and second inspection ports to be opened on the smaller sidewall. By extending the outdoor heat exchanger from the left side of the casing through the rear side to the right side of the casing, the two ends of the outdoor heat exchanger in the length direction are jointly defined to form a notch, so that the outdoor heat exchanger has a U-shaped structure. Compared with placing the notch on the left or right side of the casing, placing the notch on the front side of the casing can make the opening size of the outdoor heat exchanger smaller, thereby increasing the area of ​​the outdoor heat exchanger and thus increasing the heat exchange efficiency of the outdoor heat exchanger.

[0013] In some embodiments of this application, the electrical box includes a box body and a box cover. The box body has an opening on the side facing the front of the housing, and the box cover is located at the opening of the box body to seal the opening. The box cover is located on the side of the maintenance panel facing the inside of the housing.

[0014] In the technical solution, by making the opening of the box face the front of the casing, the box cover can be easily removed after opening the second inspection port, so as to inspect the components inside the box.

[0015] In some embodiments of this application, the electrical box is provided with a fixing plate, and electrical components are respectively installed on both sides of the fixing plate; one side of the fixing plate is disposed facing the front of the housing, and the other side of the fixing plate is disposed facing the rear of the housing.

[0016] In the technical solution, by setting one side of the fixing plate facing the front of the housing and the other side of the fixing plate facing the rear of the housing, the fixing plate is set vertically, thereby reducing the size of the electrical box in the front-rear direction of the housing, and thus reducing the space occupied by the electrical box in the housing.

[0017] In some embodiments of this application, the bottom of the housing is provided with a support portion, and the support portion is provided with an insertion portion and / or a connecting portion. The insertion portion is used for the forklift fork to insert into, and the connecting portion is used for connection with a rope.

[0018] In the technical solution, a support part is set at the bottom of the casing, and an insertion part is set on the support part to facilitate the transportation of the outdoor air conditioning unit using a forklift; a connecting part is set on the support part to connect with ropes to facilitate the transportation of the outdoor air conditioning unit by hoisting.

[0019] In some embodiments of this application, two insertion portions are provided, and the two insertion portions are arranged along the length direction of the support portion.

[0020] In some embodiments of this application, two support portions are provided, one of which is provided on the front side of the housing and the other is provided on the rear side of the housing.

[0021] In addition, this application also provides a top-discharge air conditioning outdoor unit, comprising: The casing has an air outlet on the top and an air inlet on the side; a first maintenance port is provided on the front of the casing. The heat exchanger is located inside the casing and is positioned near the air outlet. The outdoor heat exchanger is located inside the casing, with its windward side facing the air inlet and its leeward side facing the inside of the casing. The compressor is located inside the casing, on the leeward side of the outdoor heat exchanger, and below the heat exchange fan. The front cover, which is detachably connected to the housing, is used to block the first inspection port; Among them, on the projection of the bottom surface of the casing, the distance from the front side of the casing to the rear side of the casing is greater than the distance from the left side of the casing to the right side of the casing. The outdoor heat exchanger is located on the right side of the casing, passing from the left side to the rear side. Both ends of the outdoor heat exchanger along its length define a notch, which is located on the front side of the casing and corresponds to the first inspection port.

[0022] In the technical solution, the distance from the front side to the rear side of the casing is greater than the distance from the left side to the right side of the casing, and the access port is opened on the front side of the casing so that the access port is located on the side wall with a smaller casing size; by setting the notch of the outdoor heat exchanger also facing the front side of the casing, the size of the outdoor heat exchanger is increased as much as possible in the same space, thereby increasing the heat exchange area of ​​the outdoor heat exchanger and thus increasing the heat exchange effect of the outdoor heat exchanger.

[0023] In the above embodiments, a top-discharge air conditioner outdoor unit places the electrical box in front of the heat exchange fan and above the side of the compressor, and provides two independent inspection ports on the casing. One inspection port is set to correspond to the electrical box, and the other inspection port is set to correspond to the compressor, so that the electrical box and the compressor can be inspected through their respective inspection ports, thereby enabling the inspection of components such as the compressor without disassembling the electrical box.

[0026] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0027] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0028] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms can be used interchangeably where appropriate.

[0029] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0030] The top-discharge air conditioning outdoor unit provided in this application can have various implementation forms. For example... Figures 1-10 This is a specific embodiment of the top-discharge air conditioner outdoor unit of this application.

[0031] like Figures 1-3 As shown, the top-discharge air conditioner outdoor unit provided in this application includes a housing 100. The housing 100 forms the overall appearance of the air conditioner outdoor unit. The top and bottom of the housing 100 are opposite ends, and the direction from the top to the bottom of the housing 100 is the height direction of the housing 100. The left and right sides of the housing 100 are opposite sides, and the direction from the left to the right side of the housing 100 is the width direction of the housing 100. The front and rear sides of the housing 100 are opposite sides, and the direction from the front to the rear side of the housing 100 is the thickness direction of the housing 100.

[0032] like Figure 3 As shown, the housing 100 includes an air inlet 101, which is located on the side of the housing 100, and outdoor air enters the interior of the housing 100 through the air inlet 101.

[0033] The housing 100 includes an air outlet located at the top of the housing 100 with the opening facing upwards. Air inside the housing 100 is output to the outside through the air outlet.

[0034] like Figure 4 and Figure 5 As shown, the housing 100 includes a base plate 110, which is located at the bottom of the housing 100. A support portion 120 is provided at the bottom of the base plate 110, and the length of the support portion 120 is arranged along the width of the housing 100.

[0035] like Figure 6 As shown, the support part 120 is provided with an insertion part 121, which is used for the forklift forks to insert. When the outdoor unit of the air conditioner is being transported, the forklift forks are inserted into the insertion part 121 to facilitate the handling of the outdoor unit of the air conditioner.

[0036] In some embodiments, the support portion 120 is an elongated block arranged along the width direction of the housing 100, and the insertion portion 121 is a square hole provided on the support portion 120.

[0037] In some embodiments, two insertion portions 121 are provided, and the two insertion portions 121 are arranged along the length direction of the support portion 120; the length direction of the insertion portions 121 is arranged along the length direction of the support portion 120, such as... Figure 7 As shown, the length W of each insertion part 121 is greater than or equal to 140 mm, and the distance L between two insertion parts 121 is greater than or equal to 220 mm.

[0038] like Figure 6 and Figure 7 As shown, the support part 120 is provided with a connecting part 122, which is used to connect with ropes. When the outdoor unit of the air conditioner needs to be transported to a higher position, the outdoor unit of the air conditioner can be hoisted to the required position by connecting the ropes to the connecting part 122. The connecting part 122 is located at the end of the support part 120.

[0039] In some embodiments, the connecting portion 122 is a circular hole provided on the support portion 120; two connecting portions 122 are provided, and the two connecting portions 122 are respectively provided at both ends of the support portion 120 in the length direction.

[0040] In some embodiments, such as Figure 4 As shown, there are two support parts 120. One support part 120 is provided on the front side of the housing 100, and the other support part 120 is provided on the rear side of the housing 100. The insertion parts 121 on the two support parts 120 are collinear in the thickness direction of the housing 100, so that the insertion parts 121 on the two support parts 120 are aligned, so that the forks can be inserted into the insertion parts 121 of the two support parts 120 at the same time.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown, the outdoor unit of the top-discharge air conditioner includes a heat exchange fan 200, which is located inside the casing 100 and positioned near the air outlet. With the operation of the heat exchange fan 200, outdoor air enters the casing 100 through the air inlet 101, comes into contact with the outdoor heat exchanger 600, and is then output to the outside through the air outlet.

[0042] In some embodiments, the heat exchange fan 200 is an axial flow fan, and the heat exchange fan 200 is located below the air outlet.

[0043] like Figure 4 and Figure 5As shown, the outdoor unit of the top-discharge air conditioner includes an outdoor heat exchanger 600, which is located inside the casing 100 and is used to exchange heat with the air inside the casing 100. The outdoor heat exchanger 600 is located near the air inlet 101, with the windward side of the outdoor heat exchanger 600 facing the air inlet 101 and the leeward side of the outdoor heat exchanger 600 facing the inside of the casing 100. The outdoor heat exchanger 600 is mounted on the base plate 110.

[0044] like Figure 4 and Figure 5 As shown, the top-discharge outdoor unit of the air conditioner includes a compressor 700, which is located inside the casing 100 and mounted on the base plate 110. The compressor 700 is located on the leeward side of the outdoor heat exchanger 600 and below the heat exchange fan 200. The compressor 700 is used to compress the refrigerant from a low-temperature, low-pressure state to a high-temperature, high-pressure state.

[0045] like Figure 5 As shown, the compressor 700 is located in the middle part of the base plate 110, and the outdoor heat exchanger 600 is located on the outer edge of the base plate 110. The length direction of the outdoor heat exchanger 600 extends along the inner side wall of the casing 100 to form a semi-enclosed structure. The outdoor heat exchanger 600 surrounds the compressor 700. On the one hand, it can increase the area of ​​the outdoor heat exchanger 600, thereby increasing the heat exchange effect of the outdoor heat exchanger 600. On the other hand, it can make the outdoor heat exchanger 600 close to the air inlet 101 so that the air entering the casing 100 can come into contact with the outdoor heat exchanger 600 in time, thereby increasing the heat exchange effect of the outdoor heat exchanger 600.

[0046] The compressor 700, outdoor heat exchanger 600, and indoor heat exchanger together form a refrigerant circulation loop. The refrigerant flows within this loop to achieve cooling or heating of the indoor environment. When the air conditioning system is heating, the refrigerant, after being output from the compressor 700, first flows to the indoor heat exchanger and then to the outdoor heat exchanger 600. When the air conditioning system is cooling, the refrigerant, after being output from the compressor 700, first flows to the outdoor heat exchanger 600 and then to the indoor heat exchanger.

[0047] like Figure 4 and Figure 5As shown, the refrigerant circulation loop is equipped with control valves located within the housing 100. These control valves include a four-way valve 900, used to switch the refrigerant flow direction; a solenoid valve 801, used to control the on / off state of the pipeline and regulate the pipeline flow; a gas-side shut-off valve 702, used to control the on / off state of the gaseous refrigerant pipeline and regulate the pipeline flow; and a liquid-side shut-off valve 701, used to control the on / off state of the liquid refrigerant pipeline and regulate the pipeline flow. The placement, function, and structure of the four-way valve 900, solenoid valve 801, gas-side shut-off valve 702, and liquid-side shut-off valve 701 in the refrigerant circulation loop are prior art and will not be described further.

[0048] It should be noted that the control valves include, but are not limited to, four-way valve 900, solenoid valve 801, gas-side shut-off valve 702, and liquid-side shut-off valve 701. There are also some control valves located in the indoor unit of the air conditioner on the refrigerant circulation circuit, which will not be described in detail here.

[0049] like Figure 4 and Figure 5 As shown, the top-discharge air conditioner outdoor unit includes a gas-liquid separator 800, which is located on the refrigerant circulation loop and connected to the inlet end of the compressor 700 through a pipeline. The gas-liquid separator 800 is located inside the casing 100 and on the leeward side of the outdoor heat exchanger 600.

[0050] Components such as the four-way valve 900, solenoid valve 801, gas-side shut-off valve 702, liquid-side shut-off valve 701, compressor 700, and gas-liquid separator 800 are prone to damage due to the alternating action of low-pressure and high-pressure refrigerants, as well as low-temperature and high-temperature refrigerants, and require frequent maintenance or replacement. In this embodiment, for ease of description, these components and the outdoor heat exchanger 600 are collectively referred to as refrigeration components.

[0051] In some embodiments of this application, the housing 100 is provided with an inspection port, through which components, especially refrigeration components, inside the housing 100 can be inspected and repaired.

[0052] The outdoor heat exchanger 600 has a U-shaped structure. Both ends of the outdoor heat exchanger 600 in the length direction are defined by notches. The notches are set to correspond to the maintenance ports to avoid the outdoor heat exchanger 600 from blocking the compressor 700, gas-liquid separator 800 and control valves. The compressor 700, gas-liquid separator 800 and control valves can be inspected and maintained through the maintenance ports and notches.

[0053] like Figure 2As shown, the distance between the front and rear sides of the casing 100 is greater than the distance between the left and right sides of the casing 100, meaning the thickness of the casing 100 is greater than its width. This makes the size of the front sidewall of the casing 100 smaller than the sizes of the left and right sidewalls. The access panel is located on the front side of the casing 100, allowing it to be situated on a smaller sidewall. Since the outdoor heat exchanger 600 extends along the inner sidewall of the casing 100, placing the opening of the outdoor heat exchanger 600 on the front side of the casing 100 allows for a smaller opening size, thereby increasing the area of ​​the outdoor heat exchanger 600 and consequently increasing its heat exchange efficiency.

[0054] In the height direction of the housing 100, the orthographic projection of the housing 100 is rectangular, and the thickness of the housing 100 is greater than the width of the housing 100.

[0055] In some embodiments, since the housing 100 has an access panel on the front side, the air inlet 101 is located on the left, right and rear sides of the housing 100.

[0056] like Figure 1 , Figure 2 and Figure 4 As shown, the outdoor unit of a top-discharge air conditioner includes an electrical box 300. The electrical box 300 houses electrical components such as a compressor starting capacitor, a heat exchange fan capacitor, a main control relay, and a circuit board. It receives control signals from the indoor unit and distributes power to drive the compressor 700 and heat exchange fan 200. Simultaneously, through overload protectors and other devices, it monitors and protects the entire system, ensuring stable, reliable, and safe operation of the outdoor unit under various conditions. The electrical box 300 requires frequent maintenance; therefore, it is typically positioned directly opposite the access panel for easy access and repair.

[0057] In related technologies, the electrical box 300 is usually installed on the upper side of the compressor 700 and on the lower side of the heat exchange fan 200. On the orthographic projection of the rear side of the casing 100, the electrical box 300 partially overlaps with the refrigeration components and the heat exchange fan 200. This results in the electrical box 300 obstructing the refrigeration components when they are being repaired through the access port. The electrical box 300 needs to be removed first in order to repair the refrigeration components. However, the electrical box 300 has a lot of wiring harnesses, and the removal of the electrical box 300 is cumbersome. Moreover, if the wiring harnesses and components are connected in a messy manner, it may directly cause the air conditioning system to malfunction.

[0058] Based on this, in this application, the electrical box 300 is positioned directly in front of the heat exchange fan 200 and above the side of the compressor 700, so that the electrical box 300 and the compressor 700 are staggered in the height direction of the housing 100; and two independent access ports are provided on the housing 100, one access port corresponding to the electrical box 300 and the other access port corresponding to the compressor 700, so that the electrical box 300 and the compressor 700 can be inspected and maintained through their respective access ports, and the refrigeration components such as the compressor 700 can be inspected and maintained without disassembling the electrical box 300.

[0059] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the electrical box 300 is located on the side of the heat exchange fan 200 facing the front of the housing 100, and the electrical box 300 is located above the side of the compressor 700.

[0060] On the orthographic projection of the rear side of the housing 100, the electrical box 300 overlaps with the heat exchange fan 200. The electrical box 300 is located above the compressor 700, the control valve, and the gas-liquid separator 800 and does not overlap with each other, so as to avoid the electrical box 300 obstructing the compressor 700, the control valve, or the gas-liquid separator 800 in the height direction of the housing 100.

[0061] The front side of the housing 100 is provided with a first inspection port, which is set to correspond to the refrigeration component, and the refrigeration component can be inspected through the first inspection port.

[0062] The front side of the housing 100 is provided with a second access port, which corresponds to the side of the electrical box 300 away from the heat exchange fan 200. The electrical box 300 can be inspected through the second access port. The second access port is located above the first access port to avoid the electrical box 300 from obstructing the refrigeration components and to avoid disassembling the electrical box 300 when inspecting the refrigeration components. The second access port and the first access port are set independently so that the electrical box 300 and the refrigeration components can be inspected through their respective access ports to avoid mutual interference.

[0063] like Figure 1 As shown, a front cover plate 500 is provided at the first inspection port. The front cover plate 500 is detachably connected to the housing 100 and is used to block the first inspection port. When it is necessary to repair the refrigeration components, the first inspection port is opened, and the refrigeration components can be repaired through the gap of the outdoor heat exchanger 600.

[0064] In some embodiments, the front cover 500 is rotatably and detachably connected to the housing 100 to facilitate opening or closing the first access port.

[0065] like Figure 1As shown, a maintenance panel 400 is provided at the second access port. The maintenance panel 400 is detachably connected to the housing 100 and is used to block the second access port. The maintenance panel 400 is located on the side of the electrical box 300 away from the heat exchange fan 200. The front cover 500 is located below the maintenance panel 400, and the front cover 500 and the maintenance panel 400 are located on the same side of the housing 100. When it is necessary to inspect the electrical box 300, the second access port can be opened to inspect the electrical box 300.

[0066] In some embodiments, the service panel 400 is rotatably and detachably connected to the housing 100 to facilitate opening or closing the second access port.

[0067] Based on the maintenance panel 400, the front cover 500, and the first and second access ports, a first storage area and a second storage area can be defined inside the housing 100. Specifically, the maintenance panel 400 forms the sidewall of the first storage area facing the front of the housing 100, where the electrical box 300 and the heat exchange fan 200 are located; the air outlet communicates with the first storage area. The front cover 500 forms the sidewall of the second storage area facing the front of the housing 100, where the refrigeration components are located; the air inlet 101 communicates with the second storage area. The first storage area is located above the second storage area, and the first and second storage areas are independently configured.

[0068] By setting a first storage area and a second storage area inside the housing 100, the first storage area and the second storage area are set independently of each other. The maintenance panel 400 is detachably connected to the housing 100 and forms the side wall of the first storage area, so that the components located in the first storage area can be repaired by removing the maintenance panel 400. By setting the front cover 500 detachably connected to the housing 100 and forming the side wall of the second storage area, the components located in the second storage area can be repaired by removing the front cover 500. By setting the electrical box 300 and the heat exchange fan 200 in the first storage area and the outdoor heat exchanger 600 and the compressor 700 in the second storage area, the electrical box 300 is not blocked from the outdoor heat exchanger 600 and the compressor 700. The electrical box 300 and the refrigeration components can be repaired through their respective maintenance panels 400 or front covers 500.

[0069] The notch of the outdoor heat exchanger 600 is set to correspond to the first maintenance port, so as to avoid the outdoor heat exchanger 600 from blocking the compressor 700, gas-liquid separator 800 and control valve and other components. Thus, the compressor 700, gas-liquid separator 800 and control valve and other components can be inspected and maintained through the first maintenance port and the notch.

[0070] In some embodiments, the outdoor heat exchanger 600 extends from the left side of the housing 100, through the rear side of the housing 100, to the right side of the housing 100, in order to maximize the size of the outdoor heat exchanger 600 and thereby increase the heat exchange effect of the outdoor heat exchanger 600.

[0071] like Figure 9 and Figure 10 As shown, the electrical box 300 includes a box body 320, and the box body 320 has an opening on the side facing the front of the housing 100.

[0072] like Figure 9 and Figure 10 As shown, the electrical box 300 includes a cover 310, which is located at the opening of the box body 320 and is used to seal the opening of the box body 320. The cover 310 is located on the side of the service panel 400 facing the interior of the housing 100. By aligning the opening of the box body 320 with the front of the housing 100, the cover 310 can be easily removed after opening the second access port, thereby allowing for the inspection and maintenance of the components inside the box body 320.

[0073] like Figure 9 and Figure 10 As shown, the electrical box 300 is provided with a fixing plate 330, and electrical components are installed on both sides of the fixing plate 330. One side of the fixing plate 330 faces the front of the housing 100, and the other side of the fixing plate 330 faces the rear of the housing 100, so that the fixing plate 330 is vertically arranged, reducing the size of the fixing plate 330 in the front-rear direction of the housing 100, thereby reducing the size of the electrical box 300 in the front-rear direction of the housing 100, and further reducing the space occupied by the electrical box 300 in the front-rear direction of the housing 100.

[0074] For ease of description, the side of the fixing plate 330 facing the front of the housing 100 is called the front of the fixing plate 330, and the side of the fixing plate 330 facing the rear of the housing 100 is called the back of the fixing plate 330.

[0075] It should be noted that the front of the fixing plate 330 faces the box cover 310, and the back of the fixing plate 330 faces the box body 320.

[0076] like Figure 9 and Figure 10 As shown, electrical components are provided on the front and back of the mounting plate 330 to reduce the maintenance space of the electrical box 300 facing the front of the housing 100.

[0077] The electrical components include a control board 350, which is located on the front of the mounting plate 330. The control board 350 is used to receive instructions from the indoor unit and signals from various sensors (such as temperature and pressure signals). After internal program calculation, it outputs control signals to control the operating status of components such as the compressor 700 and the heat exchange fan 200.

[0078] The electrical components include a terminal block 360, which is located on the front of the mounting plate 330. The terminal block 360 includes multiple wiring terminals, which provide a neat and safe connection point for the access and branching of the high-voltage lines inside the outdoor unit. It is mainly used to reliably connect the power input line, the power line of the compressor 700, the power line of the heat exchange fan 200, etc., and to ensure the stability of the electrical connection.

[0079] The electrical components include an inductor 340, which is located on the front of the mounting plate 330. The inductor 340 is used to suppress high-frequency harmonic interference in the circuit and filter out electromagnetic noise. On the one hand, it ensures the stable operation of the outdoor unit's own control circuit, and on the other hand, it prevents the generated interference from being transmitted back through the power line, affecting the power grid quality or other electrical equipment.

[0080] The electrical components include a filter board 370, which is located on the back of the mounting plate 330. The filter board 370 is used to filter noise and purify signals of the input and output power supplies, effectively filtering out high-frequency interference signals generated by the frequency converter drive circuit and conducted to the power line, ensuring that the electromagnetic emission of the air conditioner meets the standards, and also enhancing the system's immunity to external power grid interference.

[0081] The electrical components include a drive board 380, which is located on the back of the mounting plate 330. The drive board 380 is used to convert the low-voltage control signals output by the control board 350 into high-voltage drive signals, providing stable power support for high-power actuators such as the compressor 700 and the heat exchange fan 300.

[0082] It should be noted that the electrical components include, but are not limited to, the control board 350, terminal block 360, inductor 340, filter board 370 and drive board 380. The electrical components are existing technology in this field and will not be described in detail here.

[0083] The aforementioned top-discharge air conditioner outdoor unit places the electrical box 300 in front of the heat exchange fan 200 and above the side of the compressor 700, and provides two independent access ports on the casing 100. One access port corresponds to the electrical box 300, and the other access port corresponds to the compressor 700. This allows the electrical box 300 and the compressor 700 to be inspected and repaired through their respective access ports, avoiding the electrical box 300 from obstructing the compressor 700 and other components. Thus, the compressor 700 and other components can be inspected and repaired without disassembling the electrical box 300.

[0084] The aforementioned top-discharge air conditioner outdoor unit increases the thickness of the casing 100 by making it greater than its width, and places the access panel on the front of the casing 100 so that the notch of the outdoor heat exchanger 600 also faces the front of the casing 100. This maximizes the size of the outdoor heat exchanger 600, thereby increasing its heat exchange area and ultimately its heat exchange effect.

[0085] The aforementioned top-discharge air conditioner outdoor unit reduces the space occupied by the electrical box 300 in the front-to-back direction of the housing 100 by vertically setting the fixing plate 330; and by setting the opening of the box body 320 facing the front of the housing 100 and placing the box cover 310 on the side of the maintenance panel 400 facing the inside of the housing 100, so as to facilitate opening the second inspection port to perform maintenance on the electrical box 300.

[0086] The aforementioned top-discharge air conditioner outdoor unit has a support part 120 at the bottom of the casing 100, and an insertion part 121 and a connecting part 122 on the support part 120. This allows the forklift forks to be inserted into the insertion part 121 to move the air conditioner outdoor unit, and the ropes to be connected to the connecting part 122, thereby transporting the air conditioner outdoor unit by hoisting.
