Description

Technical Field

[0001] This application relates to the field of air conditioner technology, and in particular to an electrical control box and an air conditioner. Background Technology

[0002] In modern refrigeration technology, air conditioners, as key devices for regulating indoor temperature and humidity, have internal structures whose rationality and safety directly affect performance and the safety of users' lives and property. The electrical control box, as one of the core components of an air conditioner, is responsible for controlling the power distribution and logical operation of the entire system; its stability and protection performance are crucial. In related technologies, the electrical control box is usually directly installed on the internal parts of the air conditioner, often overlooking potential safety hazards during installation and in specific environments. Especially in relatively high humidity environments, such as when the air conditioner is cooling, water vapor in the indoor air easily condenses into water droplets. When these droplets fall onto the top of the electrical control box, they can seep into the box through gaps or openings. The control box contains complex electronic components and circuit boards; once moisture enters, it can not only cause short circuits and component damage but also potentially lead to electrical fires, seriously threatening the normal operation of the air conditioner and user safety.

[0055] In this application, "multiple" means two or more (including two).

[0056] The following is for reference. Figures 1-15 The present application describes an electrical control box 100 and an air conditioner 1000 according to embodiments thereof.

[0057] like Figure 3 and Figure 4 As shown, according to the first aspect embodiment of the present application, the electrical control box 100 includes: a box body 1 and a mounting frame 2.

[0058] The mounting frame 2 is connected to the box body 1, at least a portion of the mounting frame 2 covers the top of the box body 1, and the portion of the mounting frame 2 covering the top of the box body 1 has a water guide groove 2a.

[0059] Specifically, a cavity 1a can be formed inside the box 1. The cavity 1a can be used to install and fix the internal electronic components and circuits of the control box 100 to achieve normal electrical control operation of the control box 100. At least a portion of the mounting frame 2 can cover the top of the box 1, thereby shielding the top of the box 1 and forming a protective cover. In this way, when water droplets fall onto the top of the box 1, the protective cover formed by the mounting frame 2 can block the water droplets to one side, protecting the other side of the box 1 from contact with the water droplets. This prevents water droplets from flowing into the box 1 and effectively protects the working safety of the electronic components and circuits inside the box 1. Furthermore, the portion of the mounting frame 2 covering the box 1 has a water guide channel 2a structure. The water guide channel 2a can open in the direction away from the box 1 in the height direction. The water guide channel 2a can collect water droplets falling on the mounting frame 2 and quickly guide them to a specific location for discharge. This helps to keep the mounting frame 2 and its surrounding environment dry, further ensuring the safety of the electronic components and circuits inside the box 1.

[0060] According to the electrical control box 100 of this application, water droplets can be blocked on the top side of the mounting frame 2 by at least partially shielding the top of the box body 1. The water guide channel 2a structure of the mounting frame 2 can guide the blocked water droplets to a specific location for discharge, thereby improving the waterproof performance of the electrical control box 100. This effectively solves the safety risk problem caused by water droplets flowing into the electrical control box 100, improves the working reliability and safety of the internal components of the electrical control box 100, and is beneficial to user safety and saves maintenance costs.

[0061] like Figure 4As shown, according to some embodiments of this application, the mounting frame 2 includes a top plate 21 and a side plate 22.

[0062] The top plate 21 covers the top surface of the box body 1, the side plate 22 covers the side surface of the box body 1, and the water guide groove 2a is formed on the top plate 21 and extends to the end where the top plate 21 and the side plate 22 are connected.

[0063] Specifically, the top plate 21 can extend horizontally and has a certain thickness in the height direction. The top plate 21 covers the top surface of the box 1, shielding the top of the box 1 to prevent external water droplets from dripping directly onto the top of the box 1, thus avoiding the risk of water droplets flowing into the box 1 and causing short circuits in components. The side plate 22 covers the side of the box 1. The side plate 22 can extend in the height direction, and one end of the side plate 22 is connected to the top plate 21. Together with the top plate 21, they form a relatively enclosed space on the side and top of the box 1, thereby increasing the protection against water damage. The protective range of the housing 1 further enhances the waterproof performance of the electrical control box 100. A water guide channel 2a can be formed on the top plate 21, opening towards the side opposite to the side plate 22 in the thickness direction of the top plate 21. The water guide channel 2a can extend in the same direction as the top plate 21, reaching the end where the top plate 21 connects to the side plate 22. This allows the water guide channel 2a to direct water droplets on the top plate 21 to the end where the top plate 21 connects to the side plate 22 for discharge, preventing water droplets from accumulating on the surface of the top plate 21 and preventing water droplets from entering the housing 1 from the side. Through the combination of the top plate 21 and the side plate 22, and the arrangement of the water guide channel 2a on the top plate 21, the electrical control box 100 can be further guaranteed to have good waterproof performance, effectively protecting the electronic components inside the electrical control box 100 from water damage.

[0064] like Figure 7 and Figure 8 As shown, according to some embodiments of this application, water-blocking ribs 23 are provided on both sides of the width of the top plate 21 so that the top plate 21 and the water-blocking ribs 23 define a water guide channel 2a extending along the length direction of the top plate 21, and the two ends of the length of the water guide channel 2a are open for draining accumulated water.

[0065] Specifically, the water-blocking ribs 23 protrude from the surface of the top plate 21. The water-blocking ribs 23 can extend along the length of the top plate 21 and are positioned on both sides of the width of the top plate 21, thus effectively blocking water droplets in the width direction of the top plate 21. This prevents water droplets from seeping into the box body 1 from the edge of the top plate 21, further enhancing the waterproof protection of the box body 1. The surface of the top plate 21 can help define the bottom wall of the water guide channel 2a, and the two water-blocking ribs 23 facing each other can help define the side wall of the water guide channel 2a. The top plate 21 and the water-blocking rib 23 together define a water guide channel 2a extending along the length of the top plate 21. This allows water droplets to flow along the extension direction of the water guide channel 2a to both ends of the top plate 21 in the extension direction. Both ends of the water guide channel 2a are designed to be open, so that when water flows along the length direction of the water guide channel 2a to the end, it can eventually be discharged from both ends of the water guide channel 2a, ensuring that the accumulated water is discharged in a timely and smooth manner. This effectively protects the inside of the electrical control box 100 and keeps the outside of the electrical control box 100 dry.

[0066] In addition, such as Figure 12 As shown, in some specific embodiments of this application, the water-blocking rib 23 includes: a first water-blocking rib segment 23a and a second water-blocking rib segment 23b disposed at both ends of the first water-blocking rib segment 23a. The first water-blocking rib segment 23a and the top plate 21 define a first water-guiding groove segment 20a, and the second water-blocking rib segment 23b and the top plate 21 define a second water-guiding groove segment 20b. A step is formed between the top plate 21 portion corresponding to the first water-blocking rib segment 23a and the top plate 21 portion corresponding to the second water-blocking rib segment 23b, so that the height of the second water-guiding groove segment 20b is lower than the height of the first water-guiding groove segment 20a. When water droplets fall on the top of the electrical control box 100, they first encounter the first water-blocking rib section 23a and flow along the first water-guiding channel section 20a. Then, when the water droplets reach the step, since the second water-guiding channel section 20b is located at a lower height than the first water-guiding channel section 20a, the water droplets are more easily guided to the first water-guiding channel section 20a at the end of the electrical control box 100. This improves the drainage efficiency and effect of the water-guiding channel 2a.

[0067] Furthermore, in some other specific embodiments of this application, at least a portion of the outline of the second water-blocking rib 23 segment on one side of the width direction of the top plate 21 is constructed as an arc shape, and the arc shape protrudes towards the second water-blocking rib 23 segment on the other side of the width direction of the top plate 21, so that the cross-sectional area of ​​the second water-guiding channel 2a segment is smaller than the cross-sectional area of ​​the first water-guiding channel 2a segment. This is beneficial to increase the flow velocity in the second water-guiding channel 2a segment and optimize the guiding and drainage effect of the second water-guiding channel 2a segment.

[0068] like Figure 8 and Figure 12As shown, according to some embodiments of this application, a positioning protrusion 24 is also provided on the top plate 21. The positioning protrusion 24 is located in the water guide groove 2a, and one end is connected to a water-blocking rib 23, while the other end is spaced apart from another water-blocking rib 23.

[0069] Specifically, a positioning protrusion 24 may be provided on the side of the top plate 21 away from the box body 1 in the thickness direction. The positioning protrusion 24 protrudes from the surface of the top plate 21 and is located in the water guide channel 2a. The positioning protrusion 24 may be constructed as one or multiple protrusions spaced apart in the extension direction of the water guide channel 2a. One end of the positioning protrusion 24 is connected to a water-blocking rib 23, and the other end is kept at a certain distance from another water-blocking rib 23 to ensure the water guiding and discharge functions of the water guide channel 2a. By setting the positioning protrusion 24, on the one hand, the positioning protrusion 24 can play a positioning role when the mounting frame 2 is assembled with other components (such as air duct components) in the air conditioner 1000. For example, other components in the air conditioner 1000 can form positioning grooves suitable for receiving the positioning protrusion 24 for positioning, so as to ensure that the mounting frame 2 and other components in the air conditioner 100 can be accurately connected, thereby improving the assembly accuracy and efficiency of the mounting frame 2 and the electrical control box 100 as a whole, and improving the stability and reliability of the electrical control box 100; on the other hand, by setting the positioning protrusion 24, the structural strength of the top plate 21 can be enhanced, which is conducive to improving the working reliability and service life of the top plate 21.

[0070] like Figure 12 As shown, according to some embodiments of this application, the mounting frame 2 further includes a bottom plate 25 and a back plate 26. The bottom plate 25, the top plate 21, and the side plates 22 surround the periphery of the back plate 26 and define a receiving cavity 2b. The box body 1 is disposed in the receiving cavity 2b and is connected to the back plate 26.

[0071] Specifically, the base plate 25 of the mounting frame 2 can extend horizontally and has a certain thickness in the height direction. The base plate 25 and the top plate 21 are arranged opposite each other in the height direction of the box 1. The base plate 25 serves as the bottom support structure of the mounting frame 2 and can be used to ensure the stability of the entire mounting frame 2. The back plate 26 of the mounting frame 2 can extend in the height direction. The peripheral edge of the back plate 26 is connected to the side plate 22, the top plate 21, and the base plate 25. The back plate 26, the side plate 22, the top plate 21, and the base plate 25 can jointly define the receiving cavity 2b. The size and shape of the receiving cavity 2b can match the box 1. The box 1 is set in the receiving cavity 2b and connected to the back plate 26, thereby realizing the stable connection of the box 1 to the mounting frame 2. The mounting frame 2 formed by the combination of the base plate 25, the top plate 21, the side plate 22, and the back plate 26 can provide more comprehensive waterproof protection for the box 1 of the electrical control box 100 and provide a safer and more reliable working environment for the electronic components inside the electrical control box 100. In addition, during transportation and actual use, the mounting frame 2 can also prevent the box 1 from being impacted and damaged by external forces, and can provide good impact protection for the box 1.

[0072] like Figures 8-11 As shown, according to some embodiments of this application, the side of the housing 1 is provided with a connecting ear 11 for installing a grounding screw. The side plate 22 has a protective plate 27, which is disposed opposite to the connecting ear 11, and the projected outline of the grounding screw is located between the projected outline of the protective plate 27 and the projected outline of the housing 1.

[0073] Specifically, the side of the box 1 can be provided with a connecting ear 11, and the connecting ear 11 can have multiple grounding screw holes 11a for installing multiple grounding screws to ground the electrical control box 100 and ensure the safe operation of the electrical control box 100; the side plate 22 of the mounting frame 2 has a protective plate 27, and the protective plate 27 and the connecting ear 11 can be arranged opposite to each other in the thickness direction of the back plate 26, and the projection outline of the grounding screw is located between the projection outline of the protective plate 27 and the projection outline of the box 1. It can be understood that the protective plate 27 and the box 1 enclose a relatively closed space, and the grounding screw is suitable to be housed in this space. The protective plate 27 and the box 1 together separate the area where the grounding screw is located from other areas inside the electrical control box 100.

[0074] In related technologies, when installing the grounding screw of the electrical control box 100, the grounding screw is usually exposed in the motor wire area of ​​the electrical control box 100. This can easily lead to the grounding screw wearing down or scratching the motor wire of the electrical control box 100, causing safety problems such as short circuits and fires. In this embodiment, by introducing a protective plate 27, which works in conjunction with the connecting ear 11 and the box body 1, the grounding screw can be effectively isolated from the motor wire. In this way, during grounding operations, the grounding screw will not directly contact the motor wire, thereby avoiding the risk of wear and scratching of the motor wire caused by the grounding screw, and improving the working safety and service life of the electrical control box 100.

[0075] like Figure 12 As shown, according to some embodiments of this application, the protective plate 27 includes: a first plate 27a and a second plate 27b located at both ends of the length of the first plate 27a.

[0076] The first plate 27a is positioned opposite to the length edge of the connecting ear 11, and the second plate 27b is positioned opposite to the width edge of the connecting ear 11.

[0077] Specifically, the protective plate 27 can be composed of a first plate 27a and a second plate 27b. The first plate 27a can extend in the height direction and is positioned opposite to the length edge of the connecting ear 11, so that the first plate 27a covers the area corresponding to the length direction of the connecting ear 11 in the length direction. The second plate 27b can be constructed as two plates, located at both ends of the first plate 27a in the length direction. The two second plates 27b are positioned opposite to the width edge of the connecting ear 11, so that the second plates 27b cover the width of the connecting ear 11 in the width direction. The corresponding areas are such that the first plate 27a and the second plate 27b can cooperate with the box 1 to provide all-round coverage and isolation for the grounding screw installed on the connecting ear 11. After the grounding screw is installed on the connecting ear 11, it is located in the space defined by the first plate 27a, the second plate 27b and the box 1 facing each other (inner side). The motor wires of the electrical control box 100 are located outside the first plate 27a and the second plate 27b, which can protect the motor wires from contacting the grounding screws and ensure the working safety and reliability of the motor wires.

[0078] like Figure 11 As shown, according to some embodiments of this application, the side panel 22 is spaced apart from the side of the box body 1, and the protective plate 27 is located between the box body 1 and the side panel 22.

[0079] Specifically, the side plate 22 of the mounting frame 2 is at least partially spaced from the side of the housing 1. The protective plate 27 is located in the area between the side of the housing 1 and the side plate 22. The projection of the protective plate 27 in the thickness direction of the back plate 26 is located in the area between the projections of the housing 1 and the side plate 22 in the thickness direction of the back plate 26. This ensures good isolation between the connecting screws and components such as motor wires, protecting the safety of components such as motor wires. It is understood that the spaced arrangement of the side plate 22 from the side of the housing 1 provides sufficient area for the installation and function of the protective plate 27, while also helping to ensure the compactness and rationality of the internal structure of the electrical control box 100.

[0080] like Figure 8 As shown, according to some embodiments of this application, the upper surface area of ​​the top plate 21 is greater than or equal to the top surface area of ​​the box 1.

[0081] Specifically, by setting the upper surface area of ​​the top plate 21 to be greater than or equal to the top surface area of ​​the box 1, the top plate 21 can completely cover the top of the box 1, ensuring the shielding area of ​​the top plate 21 on the top of the box 1. This ensures that when water drips from above the box 1, the top plate 21 can completely block the water droplets in the area above the box 1, effectively preventing water from flowing into the box 1 and avoiding the risk of short circuits and other safety hazards caused by water seepage. Furthermore, by setting the upper surface area of ​​the top plate 21 to be greater than or equal to the top surface area of ​​the box 1, the area of ​​the top plate 21 is increased, making the assembly of the mounting frame 2 and the box 1 more stable. This helps to optimize the vibration damping performance of the electrical control box 100, thereby further protecting the internal motor wires and other electronic components.

[0082] In addition, such as Figures 3-6 As shown, in some specific embodiments of this application, the electrical control box 100 further includes a front cover 3, a rear cover 4, and a circuit board bracket 5. The front cover 3 is disposed on the side of the mounting frame 2 facing the box body 1, and closes the accommodating cavity 2b and the cavity 1a of the box body 1. The rear cover 4 is disposed on the side of the mounting frame 2 away from the box body 1, to protect and mount the entire electrical control box 100. The circuit board bracket 5 is disposed within the cavity 1a of the box body 1, and the circuit board bracket 5 provides a stable mounting platform for the circuit board to ensure the stability of the circuit board installation within the electrical control box 100.

[0083] like Figure 1 and Figure 2As shown, the air conditioner 1000 according to the second aspect embodiment of this application includes the electrical control box 100 described in the above embodiment.
