Description

Technical Field

[0001] This utility model relates to the field of heat pumps, and in particular to a split-type heat pump housing. Background Technology

[0002] A heat pump is a highly efficient and energy-saving device that fully utilizes low-grade heat energy. Its working principle is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse circulation manner. A heat pump water heater mainly consists of a compressor, heat exchanger, axial fan, water pump, insulated water tank, electronic expansion valve, and electronic automatic controller. After being connected to a power source, it absorbs low-temperature heat energy from environmental heat sources, such as water and air, and then converts it into higher-temperature heat energy, releasing it into the circulating medium, such as water and air, becoming a high-temperature heat source output.

[0003] A combined heating and hot water unit is a device that utilizes a heat pump to integrate heating and domestic hot water functions. It includes an internal heat pump unit, a heating water tank, and a hot water tank. The heat pump unit comprises a casing and internal components such as a fan, finned heat exchanger, water pump, compressor, and water tank. During operation, the heat pump unit also needs to be connected to a duct system for air intake and exhaust.

[0004] Existing heat pump units typically have a one-piece molded casing that connects to the duct system. Therefore, maintenance of the heat pump unit requires first removing the duct system and then taking off the casing to access the internal components. This increases the complexity of the maintenance process, especially when the heat pump unit is installed in a confined space, making it even more inconvenient to operate with tools. Utility Model Content

[0005] To simplify the maintenance and inspection process of the heat pump body and avoid the problem of limited tool operation due to confined space, this application provides a split-type heat pump casing.

[0006] The split-type heat pump housing provided in this application adopts the following technical solution: A split-type heat pump housing includes a front cover and a rear cover. The rear cover is fixedly connected to a duct system, and the front cover is detachably connected to the rear cover. A fixing plate is provided at the bottom of the heat pump body, and the bottom ends of the front cover and the rear cover are detachably connected to the fixing plate, respectively.

[0007] By adopting the above technical solution, the split-type heat pump housing, by dividing the casing into a detachable front cover and a rear cover, solves the problem of difficult duct disassembly during maintenance in confined spaces with traditional integrated heat pumps. The rear cover is fixedly connected to the duct system, ensuring the integrity of the airflow path during equipment operation. At the same time, the detachable design of the front cover allows maintenance personnel to directly access the internal components of the equipment without disassembling the duct, significantly improving maintenance convenience.

[0008] Furthermore, the detachable connection between the front and rear covers and the mounting plate enhances structural stability and ensures the equipment's sealing and functionality. The heat pump described in this application is suitable for installation in compact spaces such as basements, effectively avoiding limitations on tool operation caused by confined space.

[0009] Optionally, the rear cover has a first insert and a second insert at the top and sides of the end near the front cover, respectively, and both the first insert and the second insert are located inside the rear cover. The front cover has a first gap and a second gap at the position corresponding to the first insert and the second insert, respectively, at the end near the rear cover. The first insert is inserted into the first gap and the second insert is inserted into the second gap.

[0010] By adopting the above technical solution, preliminary positioning is achieved through the cooperation of the first / second insert and the first / second gap, ensuring precise alignment during the assembly of the front and rear covers. This simplifies the assembly process of the split housing and enhances the overall connection stability of the housing. During maintenance and repair, this structure allows for quick disassembly of the front cover, improving the convenience of maintenance and repair.

[0011] Optionally, both the first and second inserts have multiple threaded holes, and multiple fixing bolts are threaded onto the front cover, with the fixing bolts threaded into the threaded holes.

[0012] By adopting the above technical solution, a stable connection between the first / second insert and the front cover is achieved through the connection of the fixing bolts and threaded holes, ensuring the overall sealing of the housing. Simultaneously, the fixing bolts can be removed to quickly separate the front and rear covers, facilitating maintenance and inspection.

[0013] Optionally, the fixing plate includes a fixing platform and an outer folded edge disposed on the periphery of the fixing platform. The outer folded edge abuts against the inner bottom end of the front cover and the rear cover. Locking bolts are provided at the bottom ends of both the front cover and the rear cover. The outer folded edge has multiple locking holes, and the locking bolts are threaded into the locking holes.

[0014] By adopting the above technical solution, the front and rear covers are quickly disassembled and assembled with the fixed plate by connecting the locking bolts with the locking holes on the outer folded edge, while ensuring the overall structural strength and airtightness of the equipment during operation.

[0015] Optionally, the rear cover has an air outlet and an air inlet. The rear cover is connected to the air outlet of the air duct system through the air outlet, and the rear cover is connected to the air inlet of the air duct system through the air inlet.

[0016] By adopting the above technical solution, the rear cover can serve as a permanent connection interface between the duct system and the heat pump body, avoiding the disassembly of the duct system during maintenance and inspection, thereby simplifying the maintenance process and reducing the impact on the airflow passage sealing.

[0017] Optionally, a wired controller is embedded in the front cover. The wired controller is used to control the heat pump body, and the bottom end of the wired controller is detachably connected to the mounting plate.

[0018] By adopting the above technical solution, the wired controller and the front cover are fixed, achieving a compact overall structure, while facilitating convenient operation and centralized control of the heat pump equipment.

[0019] Optionally, both the front and rear covers can be made by stamping metal sheets.

[0020] By adopting the above technical solution and using metal sheet stamping, the structural strength and durability of the casing can be significantly improved, while ensuring good sealing performance.

[0021] In summary, this application has the following beneficial effects: The split-type heat pump housing solves the problem of difficult duct disassembly during maintenance in confined spaces with traditional integrated heat pumps by dividing the housing into a detachable front cover and a rear cover. The rear cover is fixedly connected to the duct system, ensuring the integrity of the airflow path during equipment operation. At the same time, the detachable design of the front cover allows maintenance personnel to directly access the internal components of the equipment without disassembling the duct, significantly improving maintenance convenience.

[0022] Furthermore, the detachable connection between the front and rear covers and the mounting plate enhances structural stability and ensures the equipment's sealing and functionality. The heat pump described in this application is suitable for installation in compact spaces such as basements, effectively avoiding limitations on tool operation caused by confined space.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a split-type heat pump housing. (Refer to...) Figure 1 and Figure 2 The split-type heat pump casing is mainly used in the heat pump body 1, and the heat pump body 1, heating water tank 11, hot water tank 12, and outer casing 2 together constitute the integrated heating and hot water unit. The outer casing 2 of the integrated heating and hot water unit is a hollow cuboid shape. Inside the outer casing 2 is an inner shell, which consists of the heat pump casing and a bottom shell 21 covering the heating water tank 11 and hot water tank 12. The heat pump casing and the bottom shell 21 are connected and fixed by a retaining ring. The interior of the heat pump body 1 contains components such as an expansion tank, electrical box, heating water pump, electronic expansion valve, electronic switch, heat exchanger, fan, and electronic valve.

[0027] Reference Figure 2 The heat pump housing includes a separate front cover 4 and a rear cover 3, both of which are hollow structures used to house other components of the heat pump body 1. The rear cover 3 is fixedly connected to the duct system, while the front cover 4 is detachably connected to the rear cover 3. This detachable design allows for easy separation of the front and rear covers. When maintenance is required on the internal components of the heat pump, simply removing the front cover 4 exposes the internal components without dismantling the duct system, thus avoiding operational limitations due to limited space. A mounting plate 5 is also provided at the bottom of the heat pump body 1. The mounting plate 5 supports the other internal components, and the bottom ends of the front cover 4 and rear cover 3 are detachably connected to the mounting plate 5, which also allows for connection to the bottom shell 21.

[0028] Both the front cover 4 and the rear cover 3 are made of stamped metal sheet, thus ensuring the overall strength and sealing of the casing. A wired controller 42 is embedded in the front cover 4. The wired controller 42 is used to control the heat pump body 1, and the bottom end of the wired controller 42 is detachably connected to the mounting plate 5. The embedded wired controller 42 ensures a clean appearance while facilitating the operation of the heat pump body 1.

[0029] Reference Figure 3Regarding the connection between the rear cover 3 and the duct system, specifically, an air outlet 6 and an air inlet 61 are provided on the rear cover 3. The rear cover 3 is connected to the air outlet duct of the duct system through the air outlet 6, and the rear cover 3 is connected to the air inlet duct of the duct system through the air inlet 61. This achieves correspondence with the duct system, and the rear cover 3 serves as a permanent connection interface between the duct system and the heat pump body 1, ensuring the integrity of the airflow path during equipment operation.

[0030] Reference Figure 3 and Figure 4 For the detachable connection structure of the front cover 4 and the rear cover 3, snap-fit ​​and slot-type connections can be used. In this embodiment, both the front cover 4 and the rear cover 3 are semi-cylindrical in shape. The rear cover 3, near the front cover 4, has a first insert 31 and a second insert 32 at its top and sides, respectively, both located inside the rear cover 3. The first insert 31 and the second insert 32 extend beyond the top and sides of the rear cover 3. Correspondingly, the front cover 4, near the rear cover 3, has a first gap and a second gap at its top and sides, respectively. Therefore, when assembling the front cover 4 and the rear cover 3, inserting the first insert 31 into the first gap and the second insert 32 into the second gap allows for the positioning of the front cover 4 and enables rapid assembly.

[0031] To further secure the device, multiple threaded holes 33 are provided in both the first insert 31 and the second insert 32. Multiple fixing bolts 41 are threaded onto the front cover 4, and these bolts 41 are threaded into the threaded holes 33. The threaded holes 33 are blind holes with precision-machined inner walls to ensure reliable thread engagement. This method of tightening the fixing bolts 41 further enhances the connection strength between the front and rear covers 3, ensuring the stability of the equipment during operation.

[0032] Reference Figure 5 The fixing plate 5 includes a fixing platform 51 and an outer flange 52 disposed around the fixing platform 51. The outer flange 52 abuts against the inner bottom end of the front cover 4 and the rear cover 3. Locking bolts 43 are threaded through the bottom ends of both the front cover 4 and the rear cover 3. The outer flange 52 has multiple locking holes 53, and the locking bolts 43 are threaded into the locking holes 53. The design of the outer flange 52 not only increases the overall rigidity of the fixing plate 5 but also provides a reliable positioning reference for the front and rear covers 3. The cooperation between the locking bolts 43 and the locking holes 53 achieves precise fixing of the bottom ends of the front and rear covers 3, avoiding loosening caused by vibration or other external factors.

[0033] The implementation principle of a split-type heat pump housing in this application embodiment is as follows: By selecting a split-type heat pump housing, the front cover 4 and the rear cover 3 are detachably connected. The assembly and positioning of the front cover 4 and the rear cover 3 are achieved through the cooperation of the first insert 31 / second insert 32 and the corresponding first gap / second gap. Tightening is achieved through the cooperation of the fixing bolt 41 and the threaded hole 33. This method ensures both the need for quick disassembly and assembly during maintenance and the requirements for sealing and stability during equipment operation. This modular design significantly improves the convenience of maintenance of heat pump equipment in confined spaces. At the same time, by permanently connecting the duct system, it avoids the airflow path disruption caused by frequent disassembly and assembly of ducts in traditional solutions.

[0034] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this specific embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
