Description

Technical Field

[0001] This invention relates to the field of air source heat pump water heater technology, specifically to an integrated air source heat pump water heater that combines wall-mounted and cabinet installation. Background Technology

[0002] Air source heat pump water heaters have gradually become an important choice for household hot water supply due to their high energy efficiency ratio, low operating costs, and compliance with energy conservation and environmental protection requirements. Currently, air source heat pump water heaters are mainly divided into split-type and integrated types based on their structure. Among them, integrated air source heat pump water heaters integrate the air source heat pump components and the water storage tank into a single unit, offering advantages such as a relatively simplified installation process and higher system integrity, thus making them more popular among household users.

[0003] However, existing integrated air source heat pump water heaters generally suffer from insufficient adaptability in terms of installation methods. Current products are typically designed for only a single installation scenario, such as supporting only wall-mounted installation or only floor-standing and cabinet-embedded installation. Wall-mounted installation usually requires drilling into the wall for fixing, placing certain requirements on the wall's load-bearing capacity and structural type, and easily occupies wall space, which is detrimental to the overall interior layout. Floor-standing or cabinet-embedded installations require pre-reserved installation space, are highly dependent on the size and structure of the cabinet, and have limited applicability in small apartments or existing house renovation scenarios.

[0004] Meanwhile, existing integrated air source heat pump water heaters still have room for improvement in terms of structural integration and airflow organization. On the one hand, the arrangement of the air source heat pump components and the water storage module in traditional integrated structures is relatively fixed, and the heat exchange efficiency is limited by the structure, resulting in low heat exchange efficiency. On the other hand, after the equipment is installed, the inlet and outlet water interfaces, electrical interfaces, and other parts are often directly exposed to the outside of the unit, which not only affects the overall appearance but may also pose risks such as leakage and moisture intrusion during long-term use.

[0005] Furthermore, in cabinet-integrated installation scenarios, the air intake, exhaust, and heat dissipation conditions of air source heat pump water heaters are easily limited by the cabinet structure. If the airflow structure is not designed properly, problems such as poor airflow and interference between hot and cold air can easily occur, thus affecting the operating efficiency and stability of the air source heat pump system. Currently, there is a lack of a comprehensive solution that addresses the structural versatility, installation flexibility, and airflow optimization of integrated air source heat pump water heaters across various installation scenarios.

[0006] Therefore, it is necessary to further improve the structure and installation adaptation of existing integrated air source water heaters in order to better meet the usage needs of different family environments and installation conditions. Summary of the Invention

The hot and cold gas baffle is detachably mounted on the top of the integrated unit body for cabinet installation. The support frame is detachably mounted on the bottom of the unit body for supporting the unit body in the cabinet embedded installation state. The support frame is a non-enclosed structure, forming a ventilation space for air to pass through, allowing air to circulate freely in the bottom area of ​​the unit body. The wall-mounted mounting bracket is located on the back of the unit body for wall-mounted installation. The wall-mounted mounting bracket includes a fixing part in the middle that connects to the integrated unit body and a bearing part at both ends. The bearing part cooperates with the mounting components located on the wall.

[0009] Preferably, the air outlet and air inlet are provided with holes around them for fixing the circular air duct, so as to install the circular air duct as an accessory during wall mounting.

[0010] Preferably, the air source heat pump assembly includes a main body cover and a main body cover plate disposed on the top of the main body cover. Inside the main body cover are a fan assembly, a compressor, an evaporator, a condenser, an electrical control box, a shut-off valve, and a copper pipe assembly. The compressor, the evaporator, the condenser, and the copper pipe assembly are integrated on a first side of the fan casing. The electrical control box is disposed on a second side of the fan casing, and the fan assembly is disposed on a third side of the fan casing, with the air outlet of the fan assembly facing the air inlet of the fan casing. The main body cover plate is provided with the air inlet and an air outlet for connection to the fan casing.

[0011] Preferably, the flanged air outlet is an annular flanged structure formed by folding outward along the circumference of the fan casing. The flanged air outlet is airtightly connected to the air outlet opening on the upper cover plate of the machine body using air outlet pearl cotton. The flanged air outlet is used to form a sleeve, snap-fit, or sealed connection with the air outlet duct elbow or circular air duct to realize the switching of air outlet direction and sealed air guiding.

[0012] Preferably, the support frame includes an annular base plate, an annular top plate, and a plurality of support columns connected between the annular base plate and the annular top plate. A connecting column is provided in the middle of the annular top plate, and the connecting column has mounting holes that can be detachably installed with the bottom of the integrated body.

[0013] Preferably, the hot and cold gas partition is a plate-shaped structure with a compressible sealing edge on its circumferential edge, and the hot and cold gas partition is installed on the top of the integrated body in the cabinet embedded installation state.

[0019] Compared with the prior art, the present invention has the following beneficial effects: The air source heat pump integrated water heater that combines wall-mounted and cabinet installation provided by this invention has an integrated body that can flexibly switch between wall-mounted and cabinet embedded installation modes, which significantly improves the product's adaptability to different house structures and installation environments. In the cabinet installation state, outside air can enter through the opening at the top of the cabinet and then enter the unit through the air inlet on the side of the air source heat pump component. After heat exchange within the air source heat pump component, the air is transferred through the flanged air outlet of the fan casing to the outlet duct bend. From there, it is guided to the downward-extending outlet duct formed between the outlet duct plate and the integrated unit, allowing the heat-exchanged air to quickly descend to the bottom of the unit and be discharged through the ventilation space formed by the support frame and the opening at the bottom of the cabinet. This creates a smooth airflow path from top to bottom, preventing the mixing and accumulation of hot and cold air inside the cabinet and improving the heat exchange efficiency and operational stability of the integrated air source heat pump water heater. Simultaneously, the hot and cold air baffle effectively divides the interior space of the cabinet into an air intake area and an exhaust area, further enhancing the independence and stability of the airflow. In the wall-mounted installation state, the sealed outlet opening of the flanged air outlet on the upper cover of the unit can be directly connected to a circular air duct, guiding the heat-exchanged air to the outside or a designated area for discharge without requiring modifications to the internal structure of the unit. Therefore, while ensuring a compact structure and aesthetically pleasing appearance, this invention achieves efficient airflow guidance, reduces the adverse effects of limited installation space on air circulation, improves the overall heat exchange efficiency and operational reliability, and effectively overcomes the problems of single installation method and limited applicable scenarios of traditional integrated air source water heaters. It has the advantages of flexible installation method, clear airflow path, high heat exchange efficiency and strong adaptability. Attached Figure Description

Detailed Implementation

[0022] The embodiments described below are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] See Figures 1-9 This embodiment provides an integrated air source heat pump water heater that combines wall-mounted and cabinet installation according to the present invention, including an integrated body 10, an air outlet duct elbow 20, an air outlet duct plate 30, a support frame 40, and a wall-mounted mounting bracket 50.

[0024] Specifically, the integrated unit 10 has an integral structure, with an air source heat pump assembly 11 integrated at one end and a water storage tank 12 at the other end, thus achieving an integrated arrangement of the air source heat pump system and the water storage module. A fan casing 13 is located in the middle of the air source heat pump assembly 11. A flanged air vent 14 is located on the side of the fan casing 13 facing away from the water storage tank 12. This flanged air vent 14 is airtightly connected to the air outlet opening 17 on the upper cover plate 22 of the unit using air outlet pearl cotton. The air outlet opening 17 is selectively connected to the air outlet duct elbow 20 or the circular air duct 80 depending on the installation method, to achieve switching and guidance of the air outlet direction. Simultaneously, an air inlet 15 is also provided on the side of the air source heat pump assembly 11 away from the water storage tank 12, allowing external air to enter the air source heat pump assembly 11 and participate in heat exchange.

[0025] The air outlet duct elbow 20 is a hollow, bent air guide structure, with an internal air guide cavity for air circulation. The lower end of the air outlet duct elbow 20 has a mounting hole that mates with the air outlet opening 17 on the upper cover plate 22 of the unit body. This mounting hole connects the elbow to the air outlet opening 17, thereby guiding air from the fan casing 13 into the air outlet duct elbow 20. One end of the air outlet duct elbow 20 forms an air outlet end that fits against the side wall of the integrated unit body 10. The air outlet duct elbow 20 bends along the outer contour of the integrated unit body 10 and is detachably mounted close to the top and side walls of the integrated unit body 10, ensuring effective airflow while conforming as closely as possible to the unit's shape and minimizing external space occupation.

[0026] The air outlet duct plate 30 is located downstream of the air outlet duct elbow 20. The air outlet duct plate 30 includes an arc-shaped plate 31, which is bent inwards at both ends in the width direction to form side plates 32. The side plates 32 are fitted against the side wall of the integrated unit 10. One end of the air outlet duct plate 30 in the length direction connects to the air outlet end of the air outlet duct elbow 20, thus forming a downward-extending air outlet duct together with the outer wall of the integrated unit 10, used to guide the heat-exchanged gas to the bottom area of ​​the unit. Simultaneously, the air outlet duct plate 30 is positioned close to the integrated unit 10, saving space and improving the unit's appearance. It should be noted that the air outlet duct elbow 20 and the air outlet duct plate 30 are fixed by screws or clips.

[0027] The hot and cold gas partition 60 is detachably installed on the top of the integrated body 10 during the installation of the cabinet 70. The hot and cold gas partition 60 can separate the internal space of the cabinet 70, so that the air intake airflow entering the air source heat pump assembly 11 is isolated from the airflow discharged after heat exchange, and prevent hot and cold gases from mixing inside the cabinet 70.

[0028] The support frame 40 is detachably mounted on the bottom of the unit body and is used to support the integrated unit body 10 when it is embedded in the cabinet 70. The support frame 40 is a non-enclosed structure, which forms a ventilation space for air to pass through, allowing air to circulate freely in the bottom area of ​​the unit body, thereby ensuring smooth exhaust and providing stable support for the unit body.

[0029] The wall-mounted mounting bracket 50 is disposed on the back of the integrated unit 10 and is used for wall-mounted installation. The wall-mounted mounting bracket 50 includes a fixing part 51 disposed in the middle and connected to the integrated unit 10, and a bearing part 52 disposed at both ends and recessed to one side. The bearing part 52 is used to cooperate with the mounting components disposed on the wall, thereby realizing the reliable hanging installation of the integrated unit 10 on the wall. It should be noted that the mounting components in this application are expansion bolts 53 and nuts 54.

[0030] It should be noted that, in conjunction with the diagram... Figure 6 as well as Figure 7 When the integrated air source heat pump water heater of this application, which combines wall-mounted and cabinet installation, is wall-mounted, a load-bearing wall (concrete wall or brick wall with a thickness of ≥240mm) is selected, and the position of the wall-mounted mounting hole 45 is marked (according to the spacing between the wall-mounted bracket support parts 52 on the back of the unit, ensure horizontal alignment); then, use an impact drill to drill holes at the marked positions (hole diameter 12mm, hole depth ≥60mm), insert expansion bolts and fix them; align the support parts 52 on the back of the unit with the expansion bolts, put them in and tighten them with nuts to ensure that the unit is vertical and without tilt, so that the integrated unit 10 is reliably suspended and fixed on the wall. Meanwhile, the air inlet 15 is connected to an L-shaped circular air duct 80 with a diameter of 150mm, and the air outlet 17 on the cover plate 22 of the unit body, which is connected to the flanged air outlet 14, is connected to the L-shaped circular air duct 80 with a diameter of 150mm. This allows external air to enter the air source heat pump assembly 11 through the air inlet 15 via the circular air duct 80 to participate in heat exchange. The heat-exchanged gas is then introduced into the circular air duct 80 through the fan casing 13 and the flanged air outlet 14 and discharged to the outside or a preset area. This forms an independent and smooth air intake and exhaust channel in the wall-mounted installation state, preventing gas from flowing back or accumulating around the unit body and ensuring the normal operation and heat exchange efficiency of the air source heat pump assembly 11. With the above-mentioned wall-mounted installation method, the air source heat pump integrated water heater of this application can achieve stable and reliable wall installation and reasonable airflow organization without changing the internal structure of the unit. It not only meets the requirements of wall-mounted installation for load-bearing and safety, but also takes into account air circulation conditions and usage stability, further improving the applicability and practicality of the whole unit in different installation scenarios.

[0031] Combination Figure 4 as well as Figure 5When the wall-mounted and cabinet-mounted integrated air source heat pump water heater of this application is installed in a cabinet 70 configuration, the support frame 40 is first detachably installed to the bottom of the integrated unit 10 with bolts, providing a stable support height for the integrated unit 10 within the cabinet 70. Then, the integrated unit 10 is pushed into the cabinet 70 from the front, embedding the entire integrated unit 10 into the cabinet 70 space, ensuring the front of the unit is roughly flush with the front of the cabinet 70, thus guaranteeing overall aesthetic harmony. In the cabinet 70 installation state, the hot and cold gas baffle 60 is detachably installed on the top of the integrated unit 10, dividing the interior space of the cabinet 70 into an air intake area above the integrated unit 10 and an exhaust area around and below the integrated unit 10. External air can enter the air intake area through the cabinet air inlet at the top of the cabinet 70 and enter the integrated unit 10 through the air inlet 15 on the side of the air source heat pump assembly 11 to participate in heat exchange. After heat exchange within the air source heat pump assembly 11, the air is discharged through the fan casing 13 and enters the connected air outlet bend 20 via the flanged air vent 14 on the fan casing 13. Guided by the air outlet bend 20, the air is then directed to the downward-extending air outlet duct formed between the air outlet duct plate 30 and the outer wall of the integrated unit 10. This allows the heat-exchanged air to flow downwards along the outer side of the unit and ultimately reach the bottom area of ​​the integrated unit 10. The heat-exchanged air further passes through the ventilation space formed by the support frame 40 and is discharged outside the cabinet 70 via the cabinet air outlet reserved at the bottom of the cabinet 70, thus forming a top-down, separate inlet and outlet airflow path inside the cabinet 70. Through the aforementioned cabinet 70 installation method, the air outlet duct elbow 20 and the air outlet duct plate 30 work together to not only effectively guide the airflow direction but also ensure that the air outlet duct is closely arranged against the integrated unit 10, reducing the space occupied inside the cabinet 70. Simultaneously, the hot and cold gas baffle 60 effectively prevents the intake and exhaust airflows from interfering with each other within the cabinet 70, preventing the accumulation of hot and cold air mixtures and ensuring that the air source heat pump component 11 maintains good heat exchange conditions and operational stability even when embedded in the cabinet 70. Therefore, the air source heat pump integrated water heater of this application can achieve efficient heat exchange, a compact structure, and good installation adaptability even in cabinet 70 installation scenarios. Preferably, the air source heat pump assembly 11 includes a body cover 21 and a body cover plate 22 disposed on top of the body cover 21. The body cover 21 and the body cover plate 22 together enclose an installation cavity for accommodating the air source heat pump assembly 11. A fan assembly 23, a compressor 24, an evaporator 25, a condenser, an electrical control box 27, a shut-off valve 28, and a copper pipe assembly 29 are sequentially integrated within the body cover 21. These components are arranged according to functional zones within the body cover 21 to achieve a rational organization of airflow paths and refrigerant circulation paths.

[0032] The fan assembly 23 is used to drive the flow of external air and draw external air into the machine body. The air outlet of the fan assembly 23 is set towards the air inlet of the fan volute 13, so that the air is guided into the fan volute 13 and flows through the evaporator 25 under the action of the fan assembly 23, thereby completing the heat exchange process between the air and the refrigerant.

[0033] The compressor 24, evaporator 25, condenser, and copper pipe assembly 29 are interconnected through the copper pipe assembly 29 to form a complete refrigerant circulation loop. The compressor 24 compresses the refrigerant; the evaporator 25 allows the refrigerant to absorb heat from the air under low pressure; the condenser releases the heat from the high-temperature, high-pressure refrigerant to the water in the water tank 12; and the copper pipe assembly 29 connects the refrigerant flow between the components. A shut-off valve 28 is installed on the copper pipe assembly 29 to control or cut off the refrigerant flow during equipment maintenance, repair, or refrigerant charging.

[0034] The compressor 24, evaporator 25, condenser, and copper pipe assembly 29 are integrated on a first side of the fan casing 13, centralizing the refrigerant heat exchange components, shortening the refrigerant piping length, reducing energy loss, and improving system operating efficiency. The electrical control box 27 is located on a second side of the fan casing 13. The electrical control box 27 integrates control circuitry for controlling the operation of the fan assembly 23, compressor 24, and related actuators, providing unified control and management of the air source heat pump assembly 11's operating status, thereby improving operational stability and safety. The fan assembly 23 is located on a third side of the fan casing 13, ensuring that the airflow direction is substantially aligned with the axial direction of the fan casing 13, further optimizing the airflow path. In addition, the upper cover plate 22 of the body is provided with an air inlet 15 and an air outlet 17 for the installation of the fan volute 13. The air inlet 15 is used for external air to enter the fan assembly 23, so that the air forms a clear and orderly air intake, heat exchange and exhaust path in the upper cover plate 21 of the body, ensuring that the air source heat pump assembly 11 can operate stably and efficiently in different installation modes.

[0035] In this embodiment, the flanged air vent 14 is folded outward along the circumference of the fan volute 13 to form an annular flanged structure. This annular flanged structure forms an integrated flange around the fan volute 13, which can be used to achieve sleeve, snap-fit, or sealed connection with the air outlet duct elbow 20 or the circular air duct 80. In the cabinet 70 embedded installation state, the connecting end of the air outlet duct elbow 20 can be inserted into the flanged air vent 14 and fixed with screws or snap-fit ​​to allow air to flow smoothly in a predetermined direction, forming a smooth airflow from top to bottom. In the wall-mounted installation state, the end of the circular air duct 80 can be inserted into the flanged air vent 14 and airtightly connected by snap-fit ​​or sealing ring, thereby ensuring that the heat-exchanged air is smoothly discharged to the outside or a designated exhaust area, while avoiding air leakage or backflow.

[0036] Specifically, the support frame 40 includes an annular base plate 41, an annular top plate 42, and a plurality of support columns 43 disposed between the annular base plate 41 and the annular top plate 42. The support columns 43 securely connect the annular base plate 41 and the annular top plate 42, enabling the support frame 40 to bear the weight of the integrated unit 10 and maintain structural stability when the cabinet 70 is embedded in the installation state. A connecting column 44 is provided in the middle of the annular top plate 42. The connecting column 44 has a detachable mounting hole 45 corresponding to the bottom of the integrated unit 10. The connecting column 44 is fixedly connected to the bottom of the integrated unit 10 by bolts or screws, so that the support frame 40 can achieve stable cooperation with the unit while providing support. In addition, the support frame 40 adopts a non-enclosed design. The gap between the support column 43 between the annular bottom plate 41 and the annular top plate 42 forms a ventilation space, allowing air to circulate freely and ensuring that the air inside the cabinet 70 is smoothly discharged. Thus, while supporting the integrated body 10, it also takes into account the formation of airflow channels, achieving efficient heat exchange and operational stability of the cabinet 70 in the installed state.

[0037] Preferably, the hot and cold gas partition 60 is a plate-shaped structure with a compressible sealing edge on its circumferential edge. This sealing edge can be made of an elastic material, such as rubber, silicone, or a soft polyurethane strip, forming a continuous sealing edge around the partition. This ensures that the partition fits tightly against the top of the integrated unit 10 and the internal structure of the cabinet 70 when the cabinet 70 is embedded in the installation state, achieving an airtight seal between the partition and the unit. During installation, when the hot and cold gas partition 60 is placed on top of the integrated unit 10, the sealing edge will be slightly compressed due to the force, thereby filling any gaps that may exist between the unit and the cabinet 70, preventing the air from mixing between the air intake and exhaust areas, and ensuring smooth and controllable airflow. When the cabinet 70 is embedded in the cabinet, the hot and cold gas partition 60 effectively divides the internal space of the cabinet 70 into an upper air intake area and a lower and side exhaust area. This allows external air to enter the air intake area through the top opening of the cabinet 70 and be drawn into the unit through the air inlet 15 of the air source heat pump assembly 11 to participate in heat exchange. At the same time, the heat-exchanged gas is smoothly discharged through the fan casing 13 and the air outlet duct, preventing hot and cold gases from mixing and accumulating inside the cabinet 70. This improves the heat exchange efficiency and operational stability of the integrated air source heat pump water heater when it is installed in the cabinet 70.

[0038] Preferably, the upper cover 21 of the unit includes a first arc-shaped upper cover 211 and a second arc-shaped upper cover 212 detachably connected to the first arc-shaped upper cover 211, which together form an installation cavity for accommodating the air source heat pump assembly 11. A detachable connection structure is provided between the first arc-shaped upper cover 211 and the second arc-shaped upper cover 212. This connection structure can be a threaded detachable connection structure, a snap-fit ​​detachable connection structure, a pin detachable connection structure, or a magnetic detachable connection structure. During use, the second arc-shaped upper cover 212 can be easily removed by disassembling the connection structure, thereby facilitating the inspection, maintenance, cleaning, or replacement of the fan assembly 23, compressor 24, evaporator 25, condenser, electrical control box 27, and copper pipe assembly 29 inside the unit, and even refrigerant charging operations, without having to remove the entire integrated unit 10 from the cabinet 70. This design not only improves the ease of maintenance and operational safety of the equipment, but also ensures that the air flow path and heat exchange channel are not affected by disassembly operations while maintaining the stability of the machine structure, thereby ensuring the operating efficiency and stability of the air source heat pump integrated water heater under different installation and maintenance conditions.

[0039] For a more preferred option, please refer to Figure 8 as well as Figure 9The detachable connection structure includes threaded openings 213 on the sides of both ends of the first arc-shaped upper cover 211. The threaded openings 213 extend inward to form a first threaded post 214. Simultaneously, a second threaded post 215 corresponding to the first threaded post 214 is provided inside the second arc-shaped upper cover 212, so that reliable fixing can be achieved by bolts during installation. The detachable connection structure also includes a long strip of rubber 216. Two sidewalls at the ends of the first arc-shaped upper cover 211, opposite to the sidewalls of the second arc-shaped upper cover 212, are recessed inward to form T-shaped grooves 217. Two sidewalls at the ends of the second arc-shaped upper cover 212, opposite to the sidewalls of the first arc-shaped upper cover 211, are recessed inward to form fan-shaped grooves 218. The cross-section of the long strip of rubber 216 includes a T-shaped side 219 and a fan-shaped side 220 connected to the T-shaped side 219. During installation, the T-shaped side 219 of the elongated rubber body 216 is embedded into the T-shaped recess 217 at the end of the first arc-shaped upper cover 211, with the fan-shaped side 220 facing outwards. Then, the fan-shaped side 220 is aligned with the fan-shaped groove 218 at the end of the second arc-shaped upper cover 212 and tightened forcefully to ensure a secure fit, thus achieving a sealed connection and ensuring a tight and reliable seal after installation.

By using 3M adhesive-fixed slots, quick installation can be achieved without damaging the cabinet 70 structure, while also facilitating disassembly and replacement. If the slots are directly cut into the side wall of the cabinet 70, a more secure fixation is provided, suitable for long-term installation scenarios. When the integrated unit 10 is embedded in the cabinet 70, the snap-fit ​​edge 111 inserts into the slot, maintaining the vertical and horizontal stability of the unit and the cabinet 70, effectively preventing shaking or displacement. This also ensures simple installation and disassembly, allowing maintenance or cleaning to be completed without additional tools, thereby improving the safety, stability, and ease of maintenance of the integrated air source heat pump water heater when embedded in the cabinet 70.

[0044] Preferably, the air outlet 17 and the air inlet 15 are provided with holes around them for fixing the circular air duct 80, so as to install the circular air duct 80 as an accessory when wall-mounted.

[0045] Preferably, a filter screen 16 is provided at the air inlet 15.

[0046] The air source heat pump integrated water heater that combines wall-mounted and cabinet installation provided by the present invention allows the same unit to flexibly switch between wall-mounted installation and cabinet embedded installation by simultaneously setting a wall-mounted mounting bracket 50 and a support bracket 40 on the integrated body 10, which significantly improves the product's adaptability to different house structures and installation environments. With the cabinet 70 installed, outside air can enter through the opening at the top of the cabinet 70 and enter the unit through the air inlet 15 on the side of the air source heat pump component 11. After heat exchange within the air source heat pump component 11, the air is transferred through the flanged air outlet 14 of the fan casing 13 to the air outlet duct bend 20, and then guided by the air outlet duct bend 20 to the downward-extending air outlet duct formed between the air outlet duct plate 30 and the integrated unit 10. This allows the heat-exchanged air to quickly descend to the bottom of the unit and be discharged through the ventilation space formed by the support frame 40 and the opening at the bottom of the cabinet 70, thus forming a smooth airflow path from top to bottom. This prevents hot and cold air from mixing and accumulating inside the cabinet 70, improving the heat exchange efficiency and operational stability of the integrated air source heat pump water heater. At the same time, the hot and cold gas baffle 60 effectively divides the internal space of the cabinet 70 into an air inlet area and an air outlet area, further enhancing the independence and stability of the airflow. In wall-mounted installation mode, the air outlet 17, sealed to the flanged air vent 14 of the fan casing 13, can be directly connected to the circular air duct 80, guiding the heat-exchanged gas to the outside or a designated area for discharge, without requiring modifications to the internal structure of the unit. Therefore, this invention, while ensuring a compact structure and aesthetically pleasing appearance, achieves efficient airflow guidance, reduces the adverse effects of limited installation space on air circulation, improves the overall heat exchange efficiency and operational reliability of the unit, and effectively overcomes the problems of traditional integrated air source water heaters, such as limited installation methods and applicable scenarios. It boasts advantages such as flexible installation, clear airflow path, high heat exchange efficiency, and strong adaptability.

[0047] The above-disclosed embodiments are merely some preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
