Description

Technical Field

[0001] This utility model relates to a housing for a water source heat pump. Background Technology

[0002] As a highly efficient and energy-saving heat exchange device, water source heat pumps have been widely used in building air conditioning and industrial waste heat recovery in recent years. The casing of existing water source heat pumps generally consists of a frame, front panel, rear panel, left panel, right panel, and an internal junction box. While this design is relatively mature in ensuring the overall structural strength, sealing, and protection performance of the equipment, it has certain shortcomings in actual wiring and maintenance.

[0003] In traditional designs, to complete equipment wiring or perform routine maintenance, installers often need to remove part of the panel on the casing to expose the internal junction box and electrical connection components, and then reinstall the removed panel after the wiring is completed.

[0004] This disassembly and assembly process not only increases the number of steps and time required for construction and maintenance, but also easily leads to damage to the panels or a decline in sealing performance due to frequent disassembly, thereby affecting the normal operation and long-term reliability of the equipment. Furthermore, on-site operators often require high levels of skill and experience during disassembly and assembly, increasing the difficulty of installation and maintenance and reducing overall work efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a water source heat pump housing that allows the location of the junction box to be quickly exposed simply by flipping the top cover during wiring or maintenance, which greatly improves construction efficiency and facilitates future equipment maintenance.

[0006] The purpose of this utility model is achieved as follows:

[0007] A water source heat pump housing includes a lower housing and an upper flip cover. The lower housing includes a frame, a front plate, a rear plate, a left plate, a right plate, and a junction box. The left plate is fixed to the left side of the frame, the right plate is fixed to the right side of the frame, and the rear plate is fixed to the rear side of the frame.

[0008] The frame has locking slots on its front side near its left and right sides. The height of the front plate is less than the height of the frame. The back of the front plate is provided with locking hooks at intervals. The locking hooks are inserted into the locking slots and locked in place so that the front plate locks the frame.

[0009] The area between the upper end of the front panel and the top of the frame forms the front exposed area, the junction box is disposed inside the frame, and the area between the top of the frame and the junction box forms the top exposed area.

[0010] The upper flip cover includes a top cover plate and a front cover plate, which are integrally formed. The upper flip cover is rotatably mounted on the top of the frame. When the upper flip cover rotates to close the lower housing, the top cover plate covers the exposed area at the top, and the front cover plate covers the exposed area at the front.

[0011] The top-flip cover structure allows for quick exposure of the top and front exposed areas of the junction box without removing the panels on the housing, thus greatly simplifying wiring and subsequent maintenance steps and reducing the complexity of installation and maintenance.

[0012] Traditional designs require repeated disassembly and reassembly of the casing components, while this design allows installers to complete wiring work simply by flipping the top cover, effectively saving construction time and improving work efficiency.

[0013] By avoiding frequent disassembly of the casing, the potential damage to the casing or a decrease in sealing performance caused by repeated installation is reduced, thus enhancing the overall durability and long-term reliability of the machine.

[0014] If users need to inspect the water source heat pump system inside the water source heat pump casing, they can also choose to remove the front panel. This design achieves a firm connection between the front panel and the frame through the cooperation of hooks and slots. The design fully considers the convenience of disassembling and reinstalling the front panel, making it easy to remove and reinstall, thereby further improving the maintenance flexibility and repair efficiency of the equipment.

[0015] The objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, it also includes a hinge, one end of which is connected to the top of the frame, and the other end of which is connected to the top cover plate.

[0017] The hinge design creates a strong yet flexible swivel connection between the top cover and the top of the frame, ensuring smooth and accurate movement of the flip cover during opening and closing.

[0018] Furthermore, it also includes a support rod, the lower end of which is rotatably connected to the top of the frame, the upper end of which is provided with a hook, and the back of the top cover plate is provided with a connecting seat, the connecting seat having a hook hole.

[0019] The combined design of the support rod, hook body, connecting seat, and hook hole ensures that the top cover is stably supported in the open position when opened, effectively preventing accidental closure due to improper operation and thus ensuring the safety of maintenance personnel during wiring or maintenance. Simultaneously, wiring can be performed immediately upon opening the top cover, simplifying the wiring operation process, improving construction efficiency and maintenance convenience, and contributing to enhanced overall equipment reliability.

[0020] Furthermore, it also includes a pressure gauge, and the frame has a connecting plate in the front exposed area, on which the pressure gauge is fixed.

[0021] In this design, the pressure gauge is fixed to the connecting plate and positioned in the exposed front area. This allows users to directly observe and monitor the operating pressure of the water source heat pump system when the top cover is open, facilitating timely detection of abnormalities and appropriate action. Simultaneously, when the top cover is closed, the pressure gauge is effectively shielded, preventing external dust, moisture, or other environmental factors from affecting it and protecting the instrument from damage. This enhances equipment safety and ease of maintenance.

[0022] Furthermore, it also includes a controller, which is disposed on the front cover.

[0023] The controller is located on the front cover, making the device control more intuitive and convenient. Users can directly adjust system parameters through the controller on the front cover without disassembling the casing, improving the device's intelligence and user experience while simplifying maintenance.

[0024] Furthermore, the space between the bottom of the frame and the bottom wall of the junction box forms a housing cavity for the water source heat pump system, and the space between the top opening of the frame and the junction box forms a cable container cavity.

[0025] The space between the bottom of the frame and the bottom wall of the junction box forms the housing cavity for the water source heat pump system, while the space between the open top of the frame and the junction box forms the cable container cavity. This spatial division achieves a rational layout of the internal structure, effectively preventing cable interference and keeping the wiring neat, while also helping to prevent adverse effects of internal vibration and heat on various components, thereby improving the overall safety, ease of maintenance, and service life of the system.

[0026] Furthermore, it also includes bolts, and the lower end of the front plate is provided with a lower extension plate, the lower extension plate having bolt holes spaced apart, the bolts passing through the bolt holes and locking onto the frame.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model adopts an upper flip-top structure, which can quickly expose the top and front exposed areas where the junction box is located without removing the plate on the housing, thereby greatly simplifying the wiring and subsequent maintenance steps and reducing the complexity of installation and maintenance.

[0029] In this invention, the traditional design requires repeated disassembly and reassembly of the casing components, while the installer only needs to flip the top cover to complete the wiring work, thus effectively saving construction time and improving work efficiency.

[0030] This invention avoids frequent disassembly of the casing, reducing potential damage to the casing or a decrease in sealing performance caused by repeated installation, thus enhancing the overall durability and long-term reliability of the machine.

[0031] In this utility model, if the user needs to repair the water source heat pump system inside the water source heat pump casing, they can also choose to remove the front panel. This design achieves a firm connection between the front panel and the frame through the cooperation of hooks and locking grooves. The design fully considers the convenience of disassembling and reinstalling the front panel, making it easy to remove and reinstall, thereby further improving the maintenance flexibility and repair efficiency of the equipment.

[0032] This invention features a combined design of a support rod, hook body, connecting seat, and hook hole. This design ensures the upper cover is stably supported when opened, effectively preventing accidental closure due to improper operation and thus guaranteeing the safety of maintenance personnel during wiring or repair. Furthermore, opening the upper cover allows for immediate wiring, simplifying the wiring process, improving construction efficiency and maintenance convenience, and contributing to enhanced overall equipment reliability.
