Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more particularly to an outdoor unit for an air conditioner. Background Technology

[0002] An air conditioner typically consists of two parts: an indoor unit and an outdoor unit. The outdoor unit contains components such as a compressor, heat exchanger, fan, and electrical components, which are used to achieve cooling and heating functions. The outdoor unit is generally installed on the exterior of the building, and its structural layout must not only meet the performance requirements of the refrigeration system but also take into account the convenience of installation, maintenance, and connection.

[0003] To facilitate connection between the outdoor unit and the indoor unit or other systems after the air conditioner leaves the factory, a wiring area is usually provided on the side of the outdoor unit. This wiring area contains components such as the main control board, terminal blocks, and communication terminals between the indoor and outdoor units. This layout allows installers to perform wiring work directly from the side of the unit, improving wiring efficiency.

[0004] To ensure the safety of the generator set and prevent damage to electrical components from users or the external environment, protective covers are usually installed outside the wiring area to protect the electrical components. However, in actual use, these protective covers pose a risk of water ingress, especially in rainy or humid environments. Moisture may seep into the cover through gaps, causing the electrical components to become damp or even short-circuit, affecting the safety and reliability of the generator set. Utility Model Content

[0005] This application addresses, to at least some extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide an outdoor air conditioning unit with an optimized protective cover structure that allows external moisture to be guided out, reducing the risk of electrical components getting damp or short-circuited, and improving the safety and operational reliability of the unit.

[0007] To achieve the above objectives, this application provides an outdoor unit for an air conditioner, including a casing, an electrical mounting plate, and a protective cover. The casing defines an electrical compartment for mounting electrical components. The casing includes a first side plate adjacent to the electrical compartment, on which a wiring window is formed. The electrical mounting plate is installed in the electrical compartment and near the wiring window. The electrical mounting plate includes an electrical mounting area for mounting electrical components, the electrical mounting area facing the wiring window. The protective cover is installed on the first side plate to close the wiring window. The protective cover includes a protective cover body, a first baffle and a second baffle, and two drainage sections. The first baffle and the second baffle are located on the top of the protective cover body and extend along the width direction of the protective cover body, defining a drainage channel between the first baffle and the second baffle. The two drainage sections are located on both sides of the protective cover body, with the top surface of the two drainage sections contacting the bottom surface of the drainage channel. The two drainage sections extend downward along the height direction of the protective cover body and are located on both sides of the electrical installation area, so as to drain the water flow in the drainage channel from both sides to the outside of the electrical installation area.

[0008] In the above technical solution, the design of the first and second baffles forms a drainage channel at the top of the protective cover body. Water collected in the drainage channel will be drained downwards by the drainage parts on both sides, which can promptly remove water after it enters the protective cover. The two drainage parts are located on both sides of the electrical installation area, ensuring that the water flow area is far away from the electrical installation area, forming a spatial isolation, reducing the possibility of water vapor or droplets contacting electrical components, effectively improving the waterproof performance of the protective cover, thereby improving the safety and operational reliability of the unit.

[0009] In some embodiments, the top edge of the wiring window is inserted into the drainage channel and contacts the bottom surface of the drainage channel, and the two drainage parts respectively contact the edges on both sides of the wiring window to close the top and sides of the wiring window.

[0010] In the above technical solution, the top and sides of the protective cover form a tight fit with the first side plate, which can initially block water before it reaches the drainage channel, further improving the overall waterproof performance of the protective cover and the reliability of the electrical components.

[0011] In some embodiments, the protective cover further includes two third edges respectively disposed on both sides of the protective cover body. The two third edges extend along the height direction of the protective cover body and are coplanar with the first edge. The first edge is located outside the second edge. The outer surface of the first side plate near the wiring window is the assembly surface, and the first edge and the third edge are abutted against the assembly surface.

[0012] In the above technical solution, the first and third baffles are attached to the outer surface of the first side plate around the wiring window to form a blocking structure. This structure can effectively block the gap between the protective cover body and the wiring window, preventing external moisture, insects, dust and other foreign objects from directly entering the electrical room through the gap, thereby improving the protective effect of the protective cover on the internal components.

[0013] In some embodiments, the mounting surface is recessed inward relative to the outer surface of the first side plate, and the recess depth of the mounting surface is less than or equal to the thickness of the third flange.

[0014] In the above technical solution, the recessed design of the assembly surface can play a positioning role in the installation of the protective cover; in addition, the design of the recessed depth of the assembly surface allows rainwater flowing outside the protective cover to more easily transition to the outer surface of the first side plate when it is washed by rainwater, preventing it from entering the unit through the assembly gap and improving the waterproof effect.

[0015] In some embodiments, a protrusion is provided in the drainage channel near the second baffle, and the protrusion abuts against the side of the first side plate away from the first baffle to press the first side plate against the first baffle.

[0016] In the above technical solution, the protrusion design presses the assembly surface at the top of the wiring window against the first stop edge without reducing the effective drainage width of the drainage channel, so that the assembly surface and the first stop edge form a tight fit, reducing the assembly gap between the two and further improving the waterproof and dustproof effect.

[0017] In some embodiments, the top edge of the wiring window is bent into the electrical room to form a first folded edge, which is abutted against the bottom surface of the drainage channel; the edges on both sides of the wiring window are bent into the electrical room to form two second folded edges, which are abutted against the two drainage portions respectively.

[0018] In the above technical solution, the design of the first and second folded edges changes the assembly of the top and sides of the protective cover with the wiring window from line contact to surface contact, improving the reliability and stability of the assembly, forming a stable fit at the assembly position, better sealing the assembly gaps, and improving the waterproof sealing effect.

[0019] In some embodiments, the protective cover is configured to slide on the first side plate from bottom to top along the height direction of the first side plate. Two drainage portions are slidably engaged with two second folded edges respectively. At least one stop portion is provided on the surface of the drainage portion engaged with the second folded edges. The stop portion protrudes from the drainage portion and extends to the third stop edge. The first side plate forms limit notches on both sides of the wiring window. The limit notches are provided corresponding to the movement stroke of the stop portion as the drainage portion moves. A limit stop edge is provided in the limit notch. When the drainage portion slides along the second folded edge, the stop portion moves with the drainage portion in the limit notch. When the sliding reaches the point where the stop portion abuts against the limit stop edge, the continued sliding of the protective cover is restricted to indicate that the protective cover is installed in place.

[0020] In the above technical solution, to facilitate the installation and removal of the protective cover, the installation direction of the protective cover is guided by the sliding cooperation between the two drainage parts on both sides of the protective cover and the two second folded edges on both sides of the wiring window; at the same time, the installation position of the protective cover is accurately positioned by the cooperation between the stop parts formed on both sides of the protective cover and the limiting stop.

[0021] In some embodiments, the stop portion includes a first stop portion and a second stop portion; the first stop portion is disposed near the middle region of the drainage portion, and the first stop portion includes a first stop surface extending from the drainage portion to the third stop edge, the first stop surface and the third stop edge being disposed at an acute angle, and a first limiting portion is defined between the first stop surface and the third stop edge; the second stop portion is disposed at the bottom of the drainage portion, and the second stop portion includes a second stop surface near the third stop edge and disposed at an acute angle with the third stop edge, a third stop surface being connected between the second stop surface and the third stop edge, and a second limiting portion is defined between the second stop surface, the third stop surface and the third stop edge, and the opening direction of the second limiting portion is the same as the opening direction of the first limiting portion; The limiting notch includes a first limiting notch and a second limiting notch; the first limiting notch is provided corresponding to the first stop part, and a first limiting stop edge is provided in the first limiting notch; the second limiting notch is provided corresponding to the second stop part, and a second limiting stop edge is provided in the second limiting notch; when the protective cover is installed in place, the first limiting stop edge is limited in the first limiting part, and the second limiting stop edge is limited in the second limiting part.

[0022] In the above technical solution, stop parts with different structures are provided near the middle area and the bottom of the drainage part to form a limiting effect on different positions of the protective cover; the first stop part is located in the middle area and can easily guide the disassembly and sliding, while the second stop part is located at the bottom and has better positioning and anti-detachment effects, thereby improving the firmness and reliability of the protective cover installation.

[0023] In some embodiments, the bottom of the protective cover body extends toward and abuts the first side plate, and at least one threading portion for external wiring to pass through is provided at the bottom of the protective cover body; a threading cover is provided at the threading portion, the threading cover extends away from the protective cover body and is provided with a gradually decreasing size, the threading cover is open on the side facing the first side plate, and a threading channel is defined between the threading cover and the first side plate; a plurality of cutting portions are provided at intervals in the extending direction of the threading cover, each cutting portion including a plurality of discontinuous cutting openings located on the same plane for cutting operations.

[0024] In the above technical solution, through the design of the cable guide and the cutting section, different diameter cables are selected according to different expansion functions during the off-site wiring process, and the cutting operation is performed at the cutting section that matches the cable size. This ensures the cable can be threaded through while also satisfying the functions of dust prevention, restraint and compression of the cable.

[0025] This application also provides an outdoor unit for an air conditioner, including a housing, an electrical mounting plate, and a protective cover; the housing defines an electrical compartment for installing electrical components, and the housing includes a first side plate adjacent to the electrical compartment, on which a wiring window is formed; the electrical mounting plate is installed in the electrical compartment and faces the wiring window, and the electrical mounting plate includes an electrical mounting area for installing electrical components; the protective cover is installed on the first side plate to close the wiring window; The protective cover includes a protective cover body, a first baffle and a second baffle, and two drainage sections. The first baffle and the second baffle are located on the top of the protective cover body and extend along the width direction of the protective cover body, defining a drainage channel between the first baffle and the second baffle. The two drainage sections extend along both sides of the protective cover body from both ends of the drainage channel. The top surface of the drainage section and the bottom surface of the drainage channel form a smooth transition. The distance between the opposing surfaces of the two drainage sections is greater than the width of the electrical installation area, and the electrical installation area is located between the two drainage sections, so as to drain the water flow in the drainage channel from both sides to the outside of the electrical installation area.

[0026] In the above technical solution, the design of the first and second baffles forms a drainage channel at the top of the protective cover body. Water collected in the drainage channel will be drained downwards by the drainage parts on both sides, which can promptly drain water after it enters the protective cover. Since the distance between the drainage parts is greater than the width of the electrical installation area, and the electrical installation area is located between the two drainage parts, the water flow drawn out by the drainage parts is spatially misaligned with the electrical installation area, reducing the risk of water flow scouring or splashing on the electrical installation area, improving the waterproof effect of the protective cover, and improving the installability and operational reliability of electrical components in the unit.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. Air conditioners use a refrigerant circuit consisting of a compressor, condenser, expansion valve, and evaporator to perform a cooling or heating cycle. This cycle involves a series of processes—compression, condensation, expansion, and evaporation—to cool or heat the indoor space.

[0033] In some embodiments, the air conditioner includes an outdoor unit.

[0034] In some embodiments, the outdoor unit includes a compressor. The compressor is configured to compress a low-temperature, low-pressure refrigerant into a high-temperature, high-pressure gaseous refrigerant. The gaseous refrigerant discharged from the compressor flows into a condenser. The condenser condenses the gaseous refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0035] In some embodiments, the outdoor unit further includes an outdoor heat exchanger. The outdoor heat exchanger is configured to exchange heat with outdoor air using refrigerant flowing therein.

[0036] In some embodiments, the air conditioner also includes an indoor unit.

[0037] In some embodiments, the indoor unit includes an indoor heat exchanger. The indoor heat exchanger is configured to exchange heat with indoor air using refrigerant flowing therein. The indoor heat exchanger is connected to the outdoor heat exchanger via refrigerant piping.

[0038] In some embodiments, the air conditioner further includes an expansion valve, which may be located in the indoor unit or the outdoor unit. The expansion valve is configured to expand the high-temperature, high-pressure liquid refrigerant that has condensed in the condenser into a low-pressure liquid refrigerant. The refrigerant, after expansion by the expansion valve, enters the evaporator for evaporation. The evaporator achieves a cooling effect by utilizing the latent heat of evaporation of the refrigerant to exchange heat with the surrounding environment. The low-temperature, low-pressure refrigerant gas after passing through the evaporator returns to the compressor.

[0039] The indoor and outdoor heat exchangers function as either condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner operates in heating mode; when it is used as an evaporator, the air conditioner operates in cooling mode.

[0040] In some embodiments, the outdoor unit further includes a four-way valve connected to the refrigerant circuit. The four-way valve is configured to switch the flow direction of the refrigerant in the circuit so that the air conditioner can perform a cooling mode or a heating mode.

[0041] The working principle of an air conditioner is as follows: The compressor discharges refrigerant in a high-temperature, high-pressure state, which enters the outdoor heat exchanger (which acts as a condenser). There, the refrigerant condenses and liquefies into liquid refrigerant, releasing heat. The liquid refrigerant expands and depressurizes through the expansion valve, then enters the indoor heat exchanger (which acts as an evaporator). In the indoor heat exchanger, the refrigerant evaporates and vaporizes into gaseous refrigerant, absorbing heat from the surrounding environment. The air blown out by the indoor fan is cooled by the indoor heat exchanger coils, becoming cool air that is then blown into the room, achieving the cooling effect. The vaporized refrigerant then re-enters the compressor to begin the next cycle.

[0042] The working principle of an air conditioner for heating is as follows: gaseous refrigerant is compressed into a high-temperature, high-pressure gas by the compressor, enters the indoor heat exchanger (which acts as a condenser), condenses and liquefies into liquid refrigerant, and releases heat, thus achieving the heating effect. The liquid refrigerant expands and depressurizes through the expansion valve, enters the outdoor heat exchanger (which acts as an evaporator), evaporates and vaporizes into gaseous refrigerant, absorbs heat from the outdoor air, and re-enters the compressor to begin the next cycle.

[0043] like Figures 1-4 As shown, the outdoor unit of the air conditioner in this application includes a housing 100, which constitutes the overall appearance of the outdoor unit. The housing 100 generally has a rectangular shape. Defining the side of the outdoor unit used for mounting to a wall or other mounting base as the rear side, the housing 100 includes a front panel 110 located at the front, a rear panel located at the rear, and first side panels 120 and second side panels located on both sides.

[0044] The casing 100 contains a defined space. Typically, components such as a fan, outdoor heat exchanger, compressor, and expansion valve are installed in this space. For outdoor units of air-source heat pumps, in addition to the aforementioned conventional components, a water-refrigerant heat exchanger and water pipes are also installed in the space.

[0045] In some embodiments, such as Figure 3 As shown, a partition 200 is provided within the accommodating space, dividing the space into a horizontally adjacent fan room 101 and an electrical room 102. A fan is installed in the fan room 101 to facilitate airflow within the accommodating space. The electrical room 102 is used to install electrical components, such as drive boards, main control boards, terminal blocks 400, inductors, etc., to ensure the operation of the outdoor unit of the air conditioner.

[0046] By using a partition 200 to separate the fan room 101 from the electrical room 102, it is possible to effectively prevent the airflow generated by the fan from blowing directly onto the electrical components, and reduce the entry of liquids, dust or impurities thrown out by the fan into the electrical room 102, thereby improving the safety and reliability of the electrical components.

[0047] In some embodiments, the housing 100 further includes a front maintenance cover 130 that encloses the electrical compartment 102 at the front. The front panel 110 is connected to the front maintenance cover 130 and encloses the fan compartment 101 at the front.

[0048] like Figure 3 and Figure 4 As shown, the first side panel 120 is adjacent to the electrical room 102, and a wiring window 121 is formed on the first side panel 120. The wiring window 121 is usually a square opening.

[0049] An electrical mounting plate 300 is installed in the electrical room 102, and the electrical mounting plate 300 is close to the wiring window 121. The electrical mounting plate 300 includes an electrical mounting area for mounting electrical components, and the electrical mounting area is positioned facing the wiring window 121, so that the electrical components can be exposed through the wiring window 121 on the first side plate 120 for convenient maintenance or wiring operations.

[0050] By wiring the outdoor unit of the air conditioner from the side, the terminal block 400 electrical components used for external wiring are arranged on the side of the unit. Wiring, debugging and other operations can be carried out without removing the front maintenance cover 130, which greatly facilitates off-site wiring, maintenance and inspection operations.

[0051] To protect the electrical components inside electrical room 102 and prevent external water, dust, or insects from entering, such as Figures 1-3 As shown, a protective cover 500 is installed on the first side plate 120, which is used to close the wiring window 121. When it is necessary to repair the electrical components located at the wiring window 121, it is only necessary to remove the protective cover 500.

[0052] In this application, the structure of the protective cover 500 is optimized. By providing a drainage structure on the protective cover 500, external moisture can be guided out, preventing it from directly entering the electrical compartment 102 through the wiring window 121. Even in rain or high humidity environments, the internal electrical components can remain dry, reducing the risk of moisture and short circuits, thereby improving the safety and operational reliability of the unit. This application is implemented through the following two embodiments.

[0053] In the first implementation, such as Figures 5-12 As shown, the protective cover 500 includes a protective cover body 510. A first baffle 521 and a second baffle 522 are provided on the top of the protective cover body 510. The first baffle 521 and the second baffle 522 extend along the width direction of the protective cover body 510, respectively, and a drainage channel 523 is defined between the first baffle 521 and the second baffle 522.

[0054] Two drainage sections 530 are provided on both sides of the protective cover body 510. The top surface of the two drainage sections 530 is connected to the bottom surface of the drainage channel 523. The two drainage sections 530 extend downward along the height direction of the protective cover body 510 and are located on both sides of the electrical installation area, so as to drain the water in the drainage channel 523 from both sides to the outside of the electrical installation area.

[0055] In the above embodiment, through the design of the first baffle 521 and the second baffle 522, a drainage channel 523 is formed on the top of the protective cover body 510. External rainwater or water vapor accumulated in a high-humidity environment will penetrate through the top gap and accumulate in the drainage channel 523, avoiding direct entry into the electrical room 102 and causing damage to electrical components.

[0056] Water collected in the drainage channel 523 will be drained downwards by the drainage parts 530 on both sides, which can promptly drain water after it enters the protective cover body 510, preventing water from accumulating or stagnating inside the protective cover 500. The two drainage parts 530 are located on both sides of the electrical installation area, ensuring that the water flow area is far away from the electrical installation area, forming a spatial isolation, reducing the possibility of water vapor or droplets contacting electrical components, thereby effectively improving the waterproof performance of the protective cover 500.

[0057] In the second implementation, such as Figures 5-12 As shown, the protective cover 500 includes a protective cover body 510. A first baffle 521 and a second baffle 522 are provided on the top of the protective cover body 510. The first baffle 521 and the second baffle 522 extend along the width direction of the protective cover body 510, respectively, and a drainage channel 523 is defined between the first baffle 521 and the second baffle 522.

[0058] The protective cover body 510 also includes two drainage sections 530. The two drainage sections 530 extend from both ends of the drainage channel 523 along both sides of the protective cover body 510. The top surface of the drainage section 530 and the bottom surface of the drainage channel 523 form a smooth transition. The distance A between the opposing surfaces of the two drainage sections 530 is greater than the width of the electrical installation area, and the electrical installation area is located between the two drainage sections 530, so as to drain the water flow in the drainage channel 523 from both sides to the outside of the electrical installation area.

[0059] In the above embodiment, the top of the protective cover body 510 is defined with a drainage channel 523, which collects water that seeps in from the top gap of the protective cover 500 in the drainage channel 523 and drains it downwards from the drainage portions 530 on both sides, so as to avoid directly entering the electrical room 102 and causing damage to the electrical components.

[0060] Since the distance between the drainage sections 530 is greater than the width of the electrical installation area, and the electrical installation area is located between the two drainage sections 530, the water flow drawn out by the drainage section 530 is spatially misaligned with the electrical installation area, reducing the risk of water flow scouring or splashing on the electrical installation area, improving the waterproof effect of the protective cover 500, and improving the installability and operational reliability of electrical components in the unit.

[0061] like Figure 3 and Figure 4As shown, the electrical components installed in the electrical installation area adjacent to wiring window 121 are typically terminal blocks 400 for external wiring. Figure 4 In the illustrated embodiment, two terminal blocks 400 are installed in the electrical installation area. The width of the electrical installation area can be understood as the horizontal distance B between the left end of the left terminal block 400 and the right end of the right terminal block 400. When multiple electrical mounting plates 300 are provided in the electrical room 102, when designing the position of the drain section 530, only the electrical installation area on the electrical mounting plate closest to the wiring window 121 needs to be considered.

[0062] It is understood that the structures defined by the two implementation methods described above may overlap, but they should not be interpreted as mutually exclusive limitations.

[0063] The technical features are further described below. It should be noted that the solutions described in the following embodiments are applicable to the outdoor units of air conditioners in both of the above embodiments.

[0064] In some embodiments, when the protective cover 500 is installed on the first side plate 120, the top edge of the wiring window 121 is inserted into the drainage channel 523 and contacts and engages with the bottom surface of the drainage channel 523; at the same time, the two drainage portions 530 respectively contact and engage with the edges on both sides of the wiring window 121 to close the top and sides of the wiring window 121.

[0065] In the above embodiment, by means of the contact fit between the bottom surface of the drainage channel 523 and the top edge of the wiring window 121, and the contact fit between the drainage part 530 and the two side edges of the wiring window 121, a tight fit is formed between the protective cover 500 and the wiring window 121, which can prevent external water flow or water vapor from seeping in through the gaps on the top or sides of the protective cover 500, thereby further improving the overall waterproof performance of the protective cover 500 and the reliability of the electrical components.

[0066] The aforementioned structure can serve as a defense line before the drainage structure, initially blocking water before it reaches the drainage channel 523, thereby reducing the amount of water entering the drainage channel 523, reducing the risk of water flow scouring the electrical installation area, and further enhancing the overall waterproof performance of the protective cover 500.

[0067] In some embodiments, such as Figures 5-12 As shown, the protective cover 500 also includes two third edges 540 respectively disposed on both sides of the protective cover body 510. The two third edges 540 extend along the height direction of the protective cover body 510 and are coplanar with the first edge 521, wherein the first edge 521 is located outside the second edge 522.

[0068] like Figure 13As shown, the outer surface of the first side plate 120 near the wiring window 121 is the mounting surface 122. When the protective cover 500 is installed on the first side plate 120, the first stop 521 and the third stop 540 are abutted against the mounting surface 122.

[0069] The third edge 540 and the first edge 521 form a blocking structure located at the edge of the protective cover body 510. The first edge 521 and the third edge 540 are attached to the outer surface of the first side plate 120 around the wiring window 121, which can effectively block the gap between the protective cover body 510 and the wiring window 121, preventing external moisture, insects or dust and other foreign objects from directly entering the electrical room 102 through the gap, thereby improving the protective effect of the protective cover 500 on the internal components.

[0070] In some embodiments, the two ends of the first stop 521 are connected to the two third stopes 540, and the first stop 521 and the two third stopes 540 are continuous without gaps, thereby forming a continuous blocking structure at the edge of the protective cover body 510 and improving the protective effect.

[0071] In some embodiments, the first flange 521 and the third flange 540 are integral structures formed on the edge of the protective cover body 510 by processes such as stamping.

[0072] In some embodiments, the mounting surface 122 is recessed inward relative to the outer surface of the first side plate 120. When the protective cover 500 is mounted on the first side plate 120, the first flange 521 and the third flange 540 are located in the recessed area of ​​the first side plate 120.

[0073] The recessed design of the mounting surface 122 can play a positioning role in the installation of the protective cover 500. At the same time, the recessed design makes the area around the protective cover 500 and the wiring window 121 set inward relative to the outer surface of the first side plate 120, effectively protecting the mounting area and further preventing rainwater, dust and insects and other foreign objects from entering the electrical room 102 through the mounting gap, thus improving the reliability of protection.

[0074] In some embodiments, the recess depth of the mounting surface 122 is less than or equal to the thickness of the third retaining edge 540. In this embodiment, the first retaining edge 521 and the third retaining edge 540 have equal thicknesses. By designing the recess depth to be slightly less than or equal to the thicknesses of the first retaining edge 521 and the third retaining edge 540, the first retaining edge 521 and the third retaining edge 540 are flush with or slightly protrude from the first side plate 120.

[0075] When exposed to rain, the rainwater flowing outside the protective cover 500 can more easily transition to the outer surface of the first side plate 120, preventing it from entering the unit through assembly gaps and improving the waterproof effect.

[0076] In some embodiments, such as Figure 9 , Figure 10 as well as Figures 18-20 As shown, a protrusion 524 is provided in the drainage channel 523 near the second stop 522. The protrusion 524 abuts against the side of the first side plate 120 away from the first stop 521, so as to press the mounting surface 122 of the first side plate 120 located at the top of the wiring window 121 against the first stop 521.

[0077] By designing the protrusion 524, without reducing the effective drainage width of the drainage channel 523, the mounting surface 122 located at the top of the wiring window 121 is pressed against the first stop 521, so that the mounting surface 122 and the first stop 521 form a tight fit, reducing the assembly gap between the two and further improving the waterproof and dustproof effect.

[0078] In some embodiments, such as Figure 15 and Figure 16 As shown, the top edge of the wiring window 121 is bent into the electrical compartment 102 to form a first folded edge 123, which is abutted against the bottom surface of the drainage channel 523. With the first folded edge 123 at the top of the wiring window 121, the protrusion 524 is no longer provided in the drainage channel 523, and the first folded edge 123 can be used to press against it.

[0079] In some embodiments, such as Figure 15 and Figure 17 As shown, the edges on both sides of the wiring window 121 are bent into the electrical room 102 to form two second folded edges 124, and the two second folded edges 124 are respectively abutted against the two drain parts 530.

[0080] The design of the first folded edge 123 and the second folded edge 124 transforms the assembly of the top and sides of the protective cover 500 with the wiring window 121 from line contact to surface contact. On the one hand, surface contact provides a larger contact area, improving the reliability and stability of the assembly; on the other hand, surface contact forms a stable fit at the assembly position, thereby better sealing the assembly gaps and improving the waterproof sealing effect. Furthermore, the design of the first folded edge 123 and the second folded edge 124 can also increase the strength of the first side plate 120 in the area of ​​the wiring window 121, preventing breakage or deformation.

[0081] In some embodiments, such as Figure 17 , Figure 18 and Figure 21As shown, in the direction perpendicular to the first side plate 120, the size of the drainage part 530 is larger than the size of the second folded edge 124, so that the drainage part 530 protrudes from the second folded edge 124 in the electrical room 102, thereby ensuring that the water flow guided downward by the drainage part 530 is effectively blocked outside the electrical installation area, further ensuring the blocking and guiding effect on seepage water.

[0082] In some embodiments, the protective cover 500 is slidably mounted on the first side plate 120 from bottom to top along the height direction of the first side plate 120. During the installation of the protective cover 500, the two drainage portions 530 respectively slide and engage with the two second folded edges 124. Figure 8 and Figure 9 As shown, at least one stop portion 550 is provided on the surface of the drain portion 530 that mates with the second folded edge 124. The stop portion 550 protrudes from the drain portion 530 and extends to the third stop edge 540.

[0083] like Figure 13 and Figure 14 As shown, the first side plate 120 forms limiting notches 125 on both sides of the wiring window 121. The limiting notches 125 are set to correspond to the movement stroke of the stop part 550 as the drainage part 530 moves. A limiting stop edge 126 is formed in the limiting notch 125. During the installation of the protective cover 500, when the drainage part 530 slides along the second folded edge 124, the stop part 550 moves with the drainage part 530 in the limiting notch 125. When the sliding reaches the point where the stop part 550 abuts against the limiting stop edge 126, the continued sliding of the protective cover 500 is restricted, indicating that the protective cover 500 is installed in place.

[0084] In the above embodiment, to facilitate the installation and removal of the protective cover 500, the two drainage portions 530 on both sides of the protective cover 500 slide in cooperation with the two second folded edges 124 on both sides of the wiring window 121, thereby guiding the installation direction of the protective cover 500; at the same time, the stop portions 550 formed on both sides of the protective cover 500 cooperate with the limiting edge 126 to accurately position the installation position of the protective cover 500. Since the drainage portions 530 on both sides of the protective cover 500 are in contact with the second folded edges 124 of the first side plate 120, in order to avoid affecting the movement of the stop portions 550, a limiting notch 125 is provided on the first side plate 120 corresponding to the movement stroke of the stop portions 550. The limiting notch 125 is formed through the second folded edge 124 and the mounting surface 122.

[0085] When installing the protective cover 500, the protective cover 500 is placed against the outer surface of the first side plate 120, with its height lower than the wiring window 121. Then, the protective cover 500 is pushed upwards along the first side plate 120. The drainage channel 523 located at the top of the protective cover 500 gradually approaches the top edge of the wiring window 121, and the stop portion 550 moves upwards within the limiting notch 125. When pushed upwards until the stop portion 550 abuts against the limiting stop edge 126, the upward movement of the protective cover 500 is blocked, and the protective cover 500 is installed in place. At this time, the portion of the first side plate 120 located at the top of the wiring window 121 is inserted into the drainage channel 523 at the top of the protective cover 500, and the first folded edge 123 abuts against the bottom surface of the drainage channel 523. The first stop edge 521 and the third stop edge 540 abut against the mounting surface 122 around the wiring window 121.

[0086] To ensure the reliability of the installation of the protective cover 500, a mounting hole 560 is provided at the bottom of the protective cover 500 body. After the protective cover 500 is installed in place, the bottom of the protective cover 500 body is fixed to the first side plate 120 by screws and other fasteners.

[0087] In some embodiments, such as Figure 8 , Figure 9 and Figures 22-26 As shown, each drainage section 530 is provided with two stop sections 550. The stop section 550 includes a first stop section 551 located near the middle region of the drainage section 530 and a second stop section 552 located at the bottom of the drainage section 530. The presence of stop sections 550 in the middle region and at the bottom of the drainage section 530 provides a limiting effect on different positions of the protective cover 500. The top of the protective cover 500 is limited by the cooperation of the first and second flanges 521 and the top of the wiring window 121.

[0088] In some embodiments, such as Figure 24 As shown, the first stop portion 551 includes a first stop surface 5511 extending from the drainage portion 530 to the third stop edge 540. The first stop surface 5511 and the third stop edge 540 are set at an acute angle, and a first limiting portion 5512 is defined between the first stop surface 5511 and the third stop edge 540. Figure 13 As shown, the limiting notch 125 includes a first limiting notch 1251 provided corresponding to the first stop part 551, and a first limiting stop edge 1261 is provided in the first limiting notch 1251.

[0089] When the protective cover 500 is installed in place, the first limiting edge 1261 is confined in the first limiting part 5512. The first limiting part 5512 has an acute angle structure, which can effectively prevent the first limiting edge 1261 from continuing to move along the installation direction, but the anti-detachment effect is relatively weak.

[0090] In some embodiments, such as Figure 26 As shown, the second stop portion 552 includes a second stop surface 5521 located near and at an acute angle to the third stop edge 540. A third stop surface 5522 connects the second stop surface 5521 and the third stop edge 540. A second limiting portion 5523 is defined between the second stop surface 5521, the third stop surface 5522, and the third stop edge 540. The opening direction of the second limiting portion 5523 is the same as the opening direction of the first limiting portion 5512. Figure 13 As shown, the limiting notch 125 also includes a second limiting notch 1252 corresponding to the second stop part 552, and a second limiting stop edge 1262 is provided in the second limiting notch 1252.

[0091] When the protective cover 500 is installed in place, the second limiting edge 1262 is confined within the second limiting part 5523. The second limiting part 5523 consists of three limiting planes. Compared with the first stop part 551, it not only limits the installation direction but also effectively prevents the second limiting edge 1262 from detaching. By placing the second stop part 552, which has an anti-detachment effect, at the bottom of the drainage part 530, near the lower part of the protective cover 500, a good positioning and anti-detachment effect can be achieved at the bottom of the protective cover 500. This, combined with the anti-detachment effect provided by the first edge 521 and the second edge 522 located at the top of the protective cover 500, achieves overall installation and limiting of the protective cover 500, improving the stability of the protective cover 500 installation.

[0092] In some embodiments, such as Figure 12 As shown, the bottom of the protective cover body 510 extends towards and connects to the first side plate 120. At least one wiring pass-through portion 570 is located at the bottom of the protective cover body 510 for external wiring to pass through. The wiring pass-through portion 570 at the bottom of the protective cover body 510 prevents rainwater or dust falling from the top from entering the electrical compartment 102 through the wiring pass-through portion 570. The position and number of wiring pass-through portions 570 are designed according to the wiring requirements of the components.

[0093] In some embodiments, such as Figures 7-9 As shown, a cable guide 580 is provided at the cable threading section 570. The cable guide 580 extends away from the protective cover body 510 and is open on the side facing the first side plate 120, defining a cable threading channel between the cable guide 580 and the first side plate 120. The cable threading channel communicates with the cable threading section 570 so that the cable can enter the cable threading section 570 through the cable threading channel.

[0094] In some embodiments, the threading cover 580 is provided with a gradually decreasing size in the extending direction of the threading cover 580 and is provided with a plurality of cutting portions 581 at intervals, each cutting portion 581 including a plurality of discontinuous cutting openings located on the same plane.

[0095] During off-site wiring, cables of different diameters are selected according to different extended functions, and the cables are cut at the cut section 581 that matches the cable size. This ensures that the cables can be threaded through while also providing dust protection, restraint, and cable compression.

[0096] In some embodiments, the assembly gap between the protective cover 500 and the first side plate 120 is within 2mm, which effectively prevents insects from entering the electrical chamber 102 through the assembly gap.

[0097] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
