DETAILED DESCRIPTION

[0025] In order to make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0026] In the description of this application, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0027] In the present application, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] like Figure 1-Figure 5 As shown, this embodiment provides a junction box structure, including: a panel 1 and a box cover 2, the panel 1 is provided with a wiring port 101, the periphery of the wiring port 101 is recessed inward to form a recessed groove 102; the inner wall surface of the box cover 2 abuts against the recessed groove 102, and the outer wall surface is flush with the surface of the panel 1; the panel 1 is provided with a wire groove 3, the wire groove 3 extends to the bottom of the box cover 2, and the wire groove 3 includes a groove bottom surface 301, and a rear groove surface 305 extending upward and obliquely from the rear end of the groove bottom surface 301.

[0029] Based on the above scheme, a recessed groove 102 is designed around the wiring port 101 on the panel 1. This design enables the inner wall surface of the box cover 2 to abut against the recessed groove 102 to achieve installation positioning when the box cover 2 is installed, and the box cover 2 can be tightly abutted against the recessed groove 102, so that the outer wall surface can be kept flush with the surface of the panel 1. In this way, the junction box will not protrude from the surface of the panel 1 after installation, thereby avoiding the problem of the outer packaging box not fitting due to the protruding structure during transportation, and also improving the overall appearance of the heat pump equipment. The wire groove 3 opened on the panel 1 is partially located below the box cover 2. This layout helps to protect the wire passing area from direct influence of the external environment; more importantly, the wire groove 3 adopts a special design, including a groove bottom surface 301 and a rear groove surface 305 extending upward from the rear end of the groove bottom surface 301. This inclined design allows rainwater to naturally slide down along the inclined surface when it contacts the rear groove surface 305, reducing the possibility of rainwater accumulation in the groove. At the same time, since part of the wire trough 3 is located below the box cover 2, the box cover 2 also plays a certain shielding role, further enhancing the waterproof effect. In general, the flatness of the installation of the junction box avoids the impact of the protruding structure on the appearance of the heat pump equipment, making the heat pump equipment visually neater and more beautiful; through the special design of the sink 102 and the wire trough 3, the waterproof performance of the junction box and the heat pump equipment is effectively improved, and even in harsh rainy weather conditions, it can effectively prevent rainwater from penetrating into the equipment from the wire trough 3, protecting the equipment from damage. In addition, due to the flatness of the installation of the junction box, the heat pump equipment can better adapt to the size and shape of the outer packaging box during transportation, reducing the extra workload and cost caused by incompatible packaging. Whether from the perspective of the appearance of the heat pump equipment or the actual waterproof performance, the junction box structure of the present application brings a better user experience to users. Users do not need to worry about the protrusion of the junction box affecting the overall aesthetics of the equipment, nor do they need to worry about the equipment being damaged by water ingress in rainy weather conditions.

[0030] In order to enhance the flexibility of wiring and meet different wiring requirements, two wire troughs 3 are provided on the panel 1, and the two wire troughs 3 are spaced apart. Each wire trough 3 follows the aforementioned design principle, that is, it is partially located below the box cover 2 and includes a trough bottom surface 301 and a rear trough surface 305 extending upward from the rear end of the trough bottom surface 301. This layout of double wire troughs 3 arranged at intervals not only maintains the flatness of the junction box installation, but also makes wiring more convenient through the flexibility of the double wire troughs 3, can meet more complex wiring scenarios, and provide users with more diverse and efficient wiring solutions.

[0031] At the same time, a waterproof folding edge 103 is obliquely arranged on the panel 1, and the waterproof folding edge 103 is located on the inner side of the box cover 2 and connected between the two wire grooves 3. This solution adds an additional barrier on the basis of the original waterproof. When rainwater contacts the panel 1 and tries to penetrate, the waterproof folding edge 103 can guide the water flow to slide down along its inclined surface, effectively preventing rainwater from flowing directly to the wire groove 3 area. At the same time, the waterproof folding edge 103 is located on the inner side of the box cover 2, forming a tight waterproof layer with the box cover 2 and the panel 1, further enhancing the waterproof sealing of the entire junction box area. This design not only improves the waterproof level of the heat pump equipment, but also extends the service life of the equipment, ensuring stable operation under various severe weather conditions.

[0032] In some embodiments, the box cover 2 is provided with an inserting piece 203 protruding inwardly, and the panel 1 is provided with an inserting slot for mating with the inserting piece 203. When the box cover 2 is installed on the panel 1, the inserting piece 203 will be accurately inserted into the inserting slot to form a firm mechanical connection. This plug-in design not only simplifies the installation process and improves the installation efficiency, but also ensures the close fit between the box cover 2 and the panel 1, effectively preventing the intrusion of external impurities such as moisture and dust.

[0033] In addition, the cooperation between the plug-in piece 203 and the plug-in slot also enhances the overall strength of the junction box structure, making it difficult for the junction box to loosen or deform when subjected to external forces, thereby ensuring the stability and reliability of the heat pump device. At the same time, due to the close cooperation between the plug-in piece 203 and the plug-in slot, the waterproof performance of the junction box is further improved, providing more comprehensive and effective protection for the heat pump device.

[0034] Furthermore, it also includes a sealing strip 4, which is arranged between the sink 102 and the box cover 2. When the box cover 2 is installed on the panel 1 and fits tightly with the sink 102, the sealing strip 4 will be compressed and fill the small gap between the two, thereby preventing any external moisture, dust or other impurities from invading. The use of the sealing strip 4 not only enhances the sealing of the junction box, but also improves its weather resistance and durability. It can withstand the test of various adverse weather conditions and maintain excellent waterproof effect for a long time. At the same time, the sealing strip 4 also has a certain elastic recovery ability. Even when the box cover 2 is frequently opened and closed, it can maintain the stability and reliability of its sealing performance, making the junction box structure more perfect and providing more reliable and lasting protection for the heat pump equipment.

[0035] In order to further optimize the sealing effect and ensure the tight connection between the box cover 2 and the panel 1, the structure of the sealing strip 4 is more finely improved. Specifically, the inner circumference of the sealing strip 4 is designed to be in the shape of a concave groove 401. This design enables the box cover 2 to be perfectly embedded in the concave groove 401 during installation. In this way, a tight fitting relationship is formed between the box cover 2 and the sealing strip 4, which greatly reduces the gap between the two, thereby effectively preventing the penetration of external moisture.

[0036] At the same time, the outer peripheral surface of the sealing strip 4 is tightly abutted against the inner peripheral wall of the groove 102, so that the box cover 2 and the panel 1 achieve an interference fit, forming another solid waterproof barrier. This double protection design not only enhances the sealing performance of the junction box, but also improves its overall stability and durability. Even in extreme weather conditions, it can ensure that the inside of the junction box remains dry, providing strong guarantee for the normal operation of the heat pump equipment.

[0037] In addition, the design of the concave groove 401 makes the sealing strip 4 more convenient and quick to install and replace. The maintenance personnel only need to gently remove the box cover 2 from the concave groove 401 to easily maintain or replace the sealing strip 4, which greatly reduces the maintenance cost and difficulty.

[0038] Optionally, a fastener is further included. A first locking hole 201 is provided below the outer wall of the box cover 2, and a second locking hole 104 corresponding to the first locking hole 201 is provided on the panel 1. The fastener passes through the first locking hole 201 and is locked in the second locking hole 104. During the installation process, the fastener (such as a screw, a bolt, etc.) can pass through the first locking hole 201 and be locked in the second locking hole 104, thereby firmly fixing the box cover 2 on the panel 1. This fastening method not only enhances the overall strength of the junction box structure, but also ensures a close fit between the box cover 2 and the panel 1, and further prevents the intrusion of external impurities such as moisture and dust. At the same time, the use of fasteners also makes the disassembly and maintenance of the junction box more convenient and quick. When internal inspection or replacement of the sealing strip 4 is required, it can be easily achieved by simply loosening the fasteners.

[0039] At the same time, a locking groove 202 is provided on the outer wall of the box cover 2, and the first locking hole 201 is located in the locking groove 202. When the fastener is locked in the second locking hole 104, the fastener is located in the locking groove 202, and a sealing plug 5 capable of covering the fastener is provided on the locking groove 202. In order to further improve the overall aesthetics and waterproof performance of the junction box structure, a locking groove 202 is provided on the outer wall of the box cover 2, and a locking hole is provided inside the locking groove 202. When the fastener passes through the first locking hole 201 and is locked in the second locking hole 104 on the panel 1, the fastener will be completely located in the locking groove 202 and will not be exposed to the external environment. Moreover, in order to shield and seal the fastener, a sealing plug 5 capable of covering the fastener is also provided on the locking groove 202. The design of the sealing plug 5 closely fits the shape and size of the locking groove 202, and can effectively prevent external moisture, dust and other impurities from entering the interior of the junction box through the fastener. At the same time, the material of the sealing plug 5 also has certain elasticity and weather resistance, and can maintain an excellent sealing effect for a long time.

[0040] In addition, the locking groove 202 opened on the box cover 2 is arc-shaped, so that the locking hole is clearly visible in the locking groove 202, that is, the locking position of the fastener will not be blocked by the box cover 2, and the locking action can be completed by aligning the locking hole without squatting or bending over during assembly.

[0041] Preferably, a handle groove 204 is formed inwardly on the box cover 2. The handle groove 204 is designed to be recessed, and can reasonably and effectively use the internal space without interfering with the terminal, so as to avoid the structure on the box cover 2 protruding from the surface of the panel 1, making the overall appearance of the device more beautiful, and the honeycomb paperboards on both sides can be directly used when packing without opening a gap to avoid it.

[0042] It is worth mentioning that the overall structure of the box cover 2 is protected by galvanized plate combined with spray coating, which has higher strength and anti-aging effect than ABS (acrylonitrile-styrene-butadiene copolymer) material.

[0043] On the other hand, a heat pump is also provided, comprising a junction box structure as described in any one of the above items.
