[0026] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0028] Secondly, it should be noted that in the description of this utility model, the terms "inner" and "outer," etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0030] The electrical control box of a heat pump unit is its control hub. It can detect and adjust various operating parameters of the heat pump to ensure efficient and stable operation of the system. Simultaneously, the control box also has the ability to communicate with external devices, allowing users to remotely view and manage the heat pump unit.
[0031] In existing technology, the electrical control box of a heat pump unit is typically tightly connected to the side panel of the heat pump unit, while the electrical control box and its cover are fixed together using a snap-fit method. This design, through the matching snap-fit structure on the electrical control box and its cover, allows for a tight connection between the two during installation with a simple pressing action.
[0032] However, there is often a gap at the connection between the control box and its cover. These tiny gaps become channels for moisture and humidity to penetrate, easily infiltrating the interior of the control box and threatening the internal electronic components. Once these sensitive components are damaged, the normal operation of the heat pump unit will be affected.
[0033] To address the aforementioned issues, this application provides a waterproof structure for the electrical control box of a heat pump unit. The structure involves a wiring opening on the side plate that engages with a groove-shaped structure on the control box cover. Simultaneously, water-guiding sections with vertical water-guiding ribs are provided on both sides of the opening. These ribs press inwards towards the side plate and are covered by the side of the control box cover, forming a waterproof barrier. This combination of groove-shaped engagement and water-guiding ribs effectively prevents moisture from entering the wiring section of the control box, thereby ensuring the safe and stable operation of the heat pump unit.
[0034] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0035] Figure 1 This is a schematic diagram of the waterproof structure of the electrical control box of a heat pump unit provided in this application. This application provides a waterproof structure for the electrical control box of a heat pump unit, such as... Figure 1 As shown, a waterproof structure for the electrical control box of a heat pump unit includes: a side plate 1 of the heat pump unit and an electrical control box cover 2;
[0036] The side panel 1 has an opening for wiring the electrical control box, and the top of the electrical control box cover 2 has a groove structure 3, with the upper edge of the opening snapped into the groove structure 3.
[0037] The two sides of the opening each have a water guiding section, and the water guiding section is provided with a water guiding rib 4 in the vertical direction. The water guiding rib 4 presses against the inside of the side plate 1, and the side of the electrical control box cover 2 covers the water guiding rib 4.
[0038] The groove structure 3 can take various forms, including U-shaped grooves, V-shaped grooves, rectangular grooves, and trapezoidal grooves. For example, the height of the side of the groove structure 3 away from the side plate 1 is greater than 10mm.
[0039] A waterproof structure for the electrical control box of a heat pump unit mainly consists of a side plate 1 of the heat pump unit and a specially designed electrical control box cover 2. Through the cooperation of a series of designed components, the safety and stability of the electrical control box under various harsh weather conditions are ensured.
[0040] First, an opening is provided on side panel 1 for wiring the electrical control box. This design ensures the practical needs of connecting the electrical control box to external devices without sacrificing its waterproof performance. The top of the electrical control box cover 2 adopts a groove-shaped structure 3, and the upper edge of the opening fits perfectly into this groove-shaped structure 3. This design not only enhances the overall sealing of the electrical control box but also effectively prevents rainwater or other liquids from seeping into the electrical control box from above. In addition, this structure makes the installation between the electrical control box cover 2 and side panel 1 more secure, reducing the risk of loosening due to vibration or other external forces.
[0041] Secondly, to further enhance the waterproofing effect, water guiding sections are provided on both sides of the opening, and vertical water guiding ribs 4 are installed on these water guiding sections. These water guiding ribs 4 are designed to quickly direct any water that may flow into the opening area to the inside of the side plate 1, preventing water accumulation or penetration into the electrical control box. Simultaneously, the sides of the electrical control box cover 2 cover these water guiding ribs 4, forming a barrier that allows even if a small amount of water accidentally enters the opening area, it can be effectively drained, rather than remaining in critical areas and causing damage.
[0042] The waterproof structure of the control box in a heat pump unit can withstand various humid or waterlogged environments that the unit may encounter during operation. As one of the core components of a heat pump unit, the control box's internal circuitry and components are extremely sensitive to moisture. Water ingress into the control box can lead to serious consequences such as short circuits and component damage, thereby affecting the overall performance and lifespan of the heat pump unit. Therefore, designing this waterproof control box structure effectively prevents moisture intrusion, protects the control box and its internal components, and extends the service life of the heat pump unit.
[0043] This application provides a waterproof structure for the electrical control box of a heat pump unit, comprising: a side plate 1 of the heat pump unit and an electrical control box cover 2; the side plate 1 has an opening for wiring of the electrical control box, and the top of the electrical control box cover 2 has a groove-shaped structure 3, the upper edge of the opening being engaged in the groove-shaped structure 3; the two sides of the opening each have a water guiding part, and the water guiding part is provided with a water guiding rib 4 in the vertical direction, the water guiding rib 4 pressing against the inner side of the side plate 1, and the side of the electrical control box cover 2 covering the water guiding rib 4; this structure, through the design of the groove-shaped structure 3 engaging with the water guiding rib 4, effectively achieves the sealing and waterproofing of the electrical control box, ensuring the safe operation of the heat pump unit.
[0044] In one alternative implementation, the upper edge of the opening is in close contact with the first sidewall of the trough structure 3, and a water guide groove is formed between the upper edge of the opening and the second sidewall of the trough structure 3 located inside the side plate 1.
[0045] In the waterproof structure of the electrical control box of the heat pump unit, the upper edge of the opening is tightly fitted to the first sidewall of the groove structure 3. This design ensures a high degree of sealing at the contact surface between the two. By tightly fitting the upper edge of the opening to the first sidewall of the groove structure 3, an effective waterproof barrier is formed, preventing moisture from penetrating into the interior of the electrical control box from this interface. This design is crucial for protecting the electronic components inside the electrical control box from external moisture and water droplets. Simultaneously, it improves the stability of the entire structure and reduces the risk of failure due to external factors. Furthermore, this tight-fitting design enhances the durability of the overall structure, allowing the electrical control box to maintain its intended performance even under harsh weather conditions.
[0046] A gap is intentionally left between the upper edge of the opening and the second sidewall of the groove structure 3, rather than a complete fit, forming a water guide channel located inside the side plate 1. On the one hand, although the upper edge of the opening and the first sidewall form a good seal, tiny gaps may still exist. These gaps, though seemingly insignificant, are potential entry points for moisture. On the other hand, by setting a water guide channel between the upper edge of the opening and the second sidewall of the groove structure 3, even if a small amount of moisture seeps in through these unavoidable tiny gaps, it can be quickly guided and accumulated in the water guide channel, and then flow out along the water guide ribs 4. This effectively controls the direction of moisture flow, keeping it away from critical areas inside the electrical control box, thereby reducing the risk of damage to the circuitry.
[0047] In one alternative implementation, such as Figure 2 As shown, the water guide rib 4 extends downward to a position below the lower edge of the opening.
[0048] Firstly, the water-guiding rib 4, as an important component of the waterproof structure, primarily functions to guide water along a predetermined path, preventing water from directly entering the electrical control box or stagnating in areas where it might seep in. By designing the water-guiding rib 4 to extend downwards beyond the lower edge of the opening, it ensures that water can be effectively guided to a lower position, away from critical parts of the electrical control box.
[0049] Because the water-guiding rib 4 extends downwards to a position below the lower edge of the opening, when water flows down the surface of the side plate 1, it is further guided downwards by the water-guiding rib 4, rather than remaining around the opening or attempting to seep into the electrical control box through any tiny gaps. This not only reduces the chance of water coming into contact with the electrical control box, but also reduces the risk of water flowing backwards due to wind or other factors.
[0050] The water-guiding rib 4 helps improve the stability and durability of the overall structure. Heat pump units exposed to outdoor environments for extended periods may experience various harsh weather conditions, such as heavy rain and blizzards. The downward-extending design of the water-guiding rib 4 not only effectively removes moisture but also reduces moisture erosion of the materials themselves, thereby extending the service life of the equipment.
[0051] In one alternative implementation, such as Figure 3 As shown, the electrical control box cover 2 has water-retaining ribs 5 on both sides of the side facing the side plate 1 in the vertical direction.
[0052] In the waterproof structural design of the heat pump unit's electrical control box, vertical water-retaining ribs 5 are provided on both sides of the side panel 1 facing the control box cover 2. Firstly, as an important component of the control box cover 2, the main function of the water-retaining ribs 5 is to block and guide moisture that may seep into the control box area, ensuring that this moisture does not directly contact the internal electronic components. By providing vertical water-retaining ribs 5 on both sides of the control box cover 2, an effective physical barrier is formed between the control box and the external environment, thereby greatly reducing the risk of moisture intrusion.
[0053] For example, in rainy weather or high-humidity environments, rainwater may flow along the surface of side panel 1 and attempt to enter the electrical control box through any tiny gaps. The presence of the water-retaining ribs 5 effectively changes the direction of water flow, directing it away from critical areas. When rainwater or other liquids come into contact with the water-retaining ribs 5, their design guides the moisture to the outside of the electrical control box, preventing water accumulation or seepage into the box and causing damage. Furthermore, the design of the water-retaining ribs 5 takes into account rainfall at different angles and intensities, effectively managing both vertically falling raindrops and obliquely blowing wind and rain.
[0054] In one alternative implementation, there are multiple water-blocking ribs 5, which are arranged at equal intervals.
[0055] In the waterproof structure of the heat pump unit's electrical control box, multiple water-blocking ribs 5 are arranged at equal intervals. Firstly, multiple water-blocking ribs 5 provide more comprehensive protection. Each rib 5 effectively blocks and guides moisture that may seep into the electrical control box area. This multi-layered design significantly enhances the waterproof capability of the electrical control box. This multi-layered protection mechanism not only improves the ability to resist external moisture intrusion but also effectively copes with water flow impacts of varying intensities and directions.
[0056] When rainwater or other liquids come into contact with side panel 1, the evenly spaced water-blocking ribs 5 ensure that no matter the angle or position from which the water flows towards the control box, it will encounter at least one water-blocking rib 5. This ensures that even if some water flows around the preceding water-blocking rib 5, the subsequent water-blocking ribs 5 can still function, further guiding the water away from the critical areas of the control box. Furthermore, the evenly spaced arrangement guarantees that the water flow is evenly dispersed and guided, avoiding localized water accumulation in certain areas due to lack of protection. This helps prevent water from seeping into the control box through any tiny gaps.
[0057] In one alternative implementation, the water-blocking rib 5 and the water-guiding part are set in close contact.
[0058] First, the tight fit between the water-blocking rib 5 and the water-guiding part ensures that there are no gaps between them, thus forming a continuous and seamless protective barrier. This design effectively prevents moisture from seeping into the electrical control box through any potential gaps between the water-blocking rib 5 and the water-guiding part. The main function of the water-blocking rib 5 is to block and guide moisture that may seep into the electrical control box area, while the water-guiding part is responsible for quickly directing this moisture to the water-guiding rib 4 and expelling it from the waterproof structure of the heat pump unit's electrical control box. By ensuring close contact between the water-blocking rib 5 and the water-guiding part, the flow path of moisture can be controlled, further enhancing the waterproof effect.
[0059] When rainwater or other liquids come into contact with side panel 1, the water-blocking rib 5 prevents water from flowing directly into the electrical control box and guides it to the water guide section. Because the water-blocking rib 5 and the water guide section are installed close together, even if some water attempts to bypass the water-blocking rib 5, it will be immediately guided by the water guide section below it to the water-guiding pressure rib 4. This design not only reduces the possibility of water stagnating around the electrical control box but also avoids the risk of water seepage due to tiny gaps.
[0060] In one alternative implementation, such as Figure 4 As shown, the water guide section has a folded edge 6 that folds outward toward the side plate 1.
[0061] In the waterproof structure of the heat pump unit's electrical control box, the water guide section has a folded edge 6 that folds outwards towards the side plate 1. This structure not only enhances the heat pump unit's electrical control box's protection against external moisture but also optimizes the drainage path, ensuring that any moisture that may enter the electrical control box area can be quickly and effectively drained, avoiding damage to the internal electronic components.
[0062] When rainwater or other liquids come into contact with the side panel 1 near the control box, the moisture tends to flow along the surface of the side panel 1 and attempt to seep into the control box through various gaps. The folded edge 6 of the water-guiding section cleverly changes the direction of water flow, directing the moisture to the outside of the side panel 1, away from the critical parts of the control box. Because the design of the folded edge 6 directs the water flow directly to the external environment, it greatly reduces the possibility of moisture lingering around the control box. Even in heavy rainfall or high humidity environments, this design effectively prevents moisture accumulation, thereby reducing the risk of moisture intrusion.
[0063] Heat pump units are typically installed outdoors and must withstand various harsh weather conditions, such as heavy rain and blizzards. Therefore, the electrical control box needs to be robustly protected to meet these challenges. The outward-folding edge not only effectively drains moisture but also reduces moisture erosion of the materials themselves, thereby extending the equipment's lifespan. Especially in high-humidity areas or places with frequent seasonal rainfall, this water-guiding structure can reduce the incidence of short circuits and other malfunctions caused by moisture accumulation.
[0064] In one alternative implementation, at least one first buckle is provided on the folded edge 6, and the control box cover 2 has a second buckle corresponding to the first buckle, and the first buckle and the second buckle are engaged.
[0065] In the waterproof structure of the heat pump unit's electrical control box, at least one first buckle is provided on the folded edge 6, while the electrical control box cover 2 is equipped with a corresponding second buckle. These two buckles are connected by a snap-fit mechanism. Firstly, the buckle design provides a simple and effective method for installation and removal, allowing the electrical control box cover 2 to be quickly fixed to or removed from the side panel 1. This not only simplifies the assembly process of the electrical control box but also facilitates subsequent maintenance and repair. The installation and removal of the electrical control box cover 2 can be completed with a simple pressing or lifting action, without the need for additional tools, greatly improving work efficiency.
[0066] Specifically, the first latches are located on the folded edge 6 of the water guide section. These latches are precisely arranged to ensure that the electrical control box cover 2 can be securely attached to the side plate 1 and maintain good sealing performance. The position of each first latch is matched with the second latch on the electrical control box cover 2. When the two latches are engaged together, they form a tight and secure connection, effectively preventing the risk of the electrical control box cover 2 loosening or falling off due to vibration, wind, or other external forces.
[0067] Because the control box cover 2 and the side panel 1 are tightly connected by snaps, any possible gaps or voids are reduced, thus enhancing the overall sealing effect. Especially in the face of severe weather conditions, such as heavy rain and blizzards, this design can effectively prevent moisture from penetrating into the control box through any tiny gaps, protecting the internal electronic components from moisture corrosion.
[0068] In one alternative implementation, there is a gap between the water guide and the upper edge of the opening.
[0069] In the waterproof structure of the heat pump unit's electrical control box, a gap is provided between the water guide and the upper edge of the opening to ensure that the electrical control box cover 2 can be seamlessly snapped into the grooved structure 3 on the side plate 1. Firstly, the top of the electrical control box cover 2 has a grooved structure 3, designed to fit tightly with the upper edge of the opening, thus forming an effective waterproof barrier. However, the presence of the water guide at the opening narrows the actual width of the opening. Without proper design, this could lead to the electrical control box cover 2 not being installed correctly or gaps remaining after installation, affecting the overall waterproofing effect. Therefore, a certain gap is intentionally left between the water guide and the upper edge of the opening to compensate for the change in opening width caused by the water guide, ensuring that the electrical control box cover 2 can smoothly and seamlessly snap into the opening.
[0070] Specifically, to ensure that the electrical control box cover 2 perfectly fits the opening of the side panel 1, the width of the opening at a certain distance from the upper edge of the opening needs to be consistent with the width of the channel structure 3. If the width of the opening is narrowed due to the presence of the water guide, directly performing the snap-fit operation without proper adjustment may result in an insecure snap-fit or gaps, both of which will negatively impact the waterproofing effect. By setting appropriate intervals, the necessary space can be provided for the opening, allowing its width to adapt to the requirements of the channel structure 3, thereby ensuring that the upper edge of the opening can be accurately snapped into the channel structure 3, achieving a seamless connection and excellent waterproofing performance.
[0071] This application provides a heat pump unit, including: a housing, a heat exchange component, an electrical control box, and a waterproof structure for the electrical control box as described above. The electrical control devices in the heat exchange component and the electrical control box are disposed inside the housing. The heat exchange component is electrically connected to the electrical control box. The housing includes a side plate 1 in the waterproof structure of the electrical control box.
[0072] A heat pump unit integrates a housing, heat exchange components, an electrical control box, and a specific waterproof structure for the electrical control box. In this heat pump unit, the heat exchange components and the electrical control devices within the electrical control box are all housed inside the housing. The heat exchange components, responsible for heat exchange, are one of the core components of the heat pump unit, while the electrical control box houses various electronic components that control the operation of the heat pump unit. Specifically, this heat pump unit also employs the aforementioned waterproof structure for the electrical control box, with a portion of the housing—side plate 1—being a crucial component of this waterproof structure. This design ensures stable operation of the heat pump unit even in high humidity or humid environments, extending the unit's service life.
[0073] The heat pump unit incorporates a waterproof structure including the electrical control box. Firstly, heat pump units are typically installed outdoors or in relatively open environments, making them susceptible to damage from rainwater, snowmelt, and other natural water sources. As the unit's "brain," the electrical control box's internal electronic components are extremely sensitive to moisture; water ingress can lead to short circuits, damage, or even safety accidents. Therefore, a waterproof structure effectively protects the electrical control box from moisture. Secondly, the electrical connection between the heat exchange components and the electrical control box requires high reliability, and the waterproof structure helps maintain the stability of this connection, preventing poor contact or short circuits caused by moisture. Finally, this design also enhances the overall reliability and durability of the heat pump unit, enabling it to maintain high efficiency in various harsh environments.

However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
