The following embodiments are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0023] Embodiment:

[0024] As Figures 1 to 2As shown in the figure, the present invention provides an air source heat pump water heater that can be installed in a wardrobe. The air source heat pump water heater that can be installed in a wardrobe includes an installation bottom plate 11. Through the setting of the installation bottom plate 11, a stable foundation can be provided for the entire device, improving the structural stability of the device. An installation partition 12 is clamped inside the installation bottom plate 11. Users can install different parts through the installation partition 12, enabling the device to achieve a more reasonable layout, improving the space utilization rate of the device, and enhancing the user's ability to plan the internal space. On both sides of the installation bottom plate 11, a first installation side plate 13 and a second installation side plate 14 are respectively detachably connected. Through the setting of the first installation side plate 13 and the second installation side plate 14, the installation and maintenance of the device can be conveniently carried out, enabling users to replace or repair the first installation side plate 13 and the second installation side plate 14 according to needs, and improving the maintainability of the device. Above the installation bottom plate 11, there is an installation top plate 19. Users can close and protect the top of the device through the installation top plate 19, enabling the device to effectively prevent dust and sundries from entering the interior and improving the protection performance of the device. At the bottom of the installation bottom plate 11, there is a water tank 20. Users can store water through the water tank 20, enabling the device to accommodate the heated water body, ensuring that users can obtain hot water at any time, reducing the heat loss of the device, and maintaining the water temperature stability. In addition, through this structure, the device is modularly assembled. Users can deploy it according to the internal dimensions of the wardrobe. During installation, first fix the water tank 20 on the bottom load-bearing beam of the wardrobe, then install the installation bottom plate 11 on the top of the water tank 20. Next, carry out functional partitioning by embedding the installation partition 12 through the opening structure and bolts, and pre-assemble the parts through the opened slots. The first installation side plate 13 and the second installation side plate 14 on both sides are set with bolts and positioning holes. During maintenance, only one side needs to be disassembled to complete the inspection of multiple groups of parts. The top installation top plate 19 realizes a concealed air flow circulation through the original ventilation opening of the wardrobe.

[0025] One end of the installation base plate 11 is provided with a controller 15. The user can control the operation of the device through the controller 15, enabling the user to conveniently adjust the working mode of the water heater, improving the operation convenience of the device. The other end of the installation base plate 11 is provided with a sound insulation box 16. Through the setting of the sound insulation box 16, the noise generated during the operation of the compressor 18 can be effectively reduced, enabling the device to work in a quiet environment, improving the sound insulation effect of the device, and enhancing the user experience. Above the installation partition 12, a heat collection component is arranged. The heat collection component can promote air flow, making heat exchange more efficient and improving the heating efficiency of the device. One end of the heat collection component is provided with an evaporator 17. The user can absorb the heat in the air through the evaporator 17, enabling the device to obtain sufficient heat energy and improving the energy utilization efficiency of the device. One side of the evaporator 17 is provided with a compressor 18. The compressor 18 can compress the refrigerant, enabling the device to heat normally and improving the core working performance of the device. One side of the compressor 18 is provided with an expansion valve 101. The user can adjust the flow rate of the refrigerant through the expansion valve 101, enabling the device to heat flexibly according to different requirements and improving the heating flexibility of the device. When the controller 15 receives a hot water demand instruction, it starts the compressor 18 to drive the refrigerant to circulate. The air enters the device through the wardrobe ventilation opening, successively absorbs the ambient heat through the evaporator 17, is pressurized and heated by the compressor 18, completes condensation and heat release in the sound insulation box 16, and is throttled and depressurized by the expansion valve 101 to form a cycle. The directional air flow generated by the heat collection component cooperates with the evaporator 17 to achieve latent heat recovery.

[0026] The heat collection component includes an installation box 21. The setting of the installation box 21 can provide a stable installation position, making the parts operate more stably and improving the reliability of the device operation. The installation box 21 is arranged above the controller 15, making the device structure more compact and improving the space utilization rate. One end of the installation box 21 is provided with an air distribution plate 22, which can evenly distribute the air flow, making heat exchange more uniform and improving the heating effect of the device. Two groups of fans 23 for heat collection are clamped in the installation box 21 to enhance the air flow speed, making heat collection more efficient and improving the working efficiency of the device. The two groups of fans 23 are both electrically connected to the controller 15, enabling precise speed regulation control, so that the user can adjust the wind speed according to actual needs and improve the use flexibility of the device. The conventional design scheme of an air source heat pump is to use an axial flow fan or a centrifugal fan. For an air source heat pump water heater proposed by the present invention, in order to reduce noise, a chassis fan used for computer mainframe heat dissipation is used. At the same time, considering that a single fan 23 with a high wind speed will generate a certain amount of noise, two groups of fans 23 are adopted to meet the low-noise requirement.

[0027] The air distribution plate 22 is detachably connected to the evaporator 17 and the installation box 21 respectively, which can facilitate the disassembly, maintenance or replacement of the air distribution plate 22, making it more convenient for users to operate and improving the maintainability of the device. The bottom of the evaporator 17 is arranged on the air distribution plate 22, providing stable support for the evaporator 17, making the evaporator 17 more stable during operation and improving the operation stability of the device. The detachable connection between the bottom of the air distribution plate 22 and the installation partition 12 improves the assembly convenience of the device.

[0028] The bottom of the installation top plate 19 is detachably connected to the first installation side plate 13, the second installation side plate 14 and the sound insulation box 16 respectively, which can facilitate the disassembly and installation of the installation top plate 19, making it easier for users to perform equipment maintenance or component replacement and improving the maintenance convenience of the device. The first installation side plate 13 and the second installation side plate 14 are symmetrically installed to enhance the overall structural stability of the device, making the device more stable during operation and improving the reliability of the device. The controller 15 and the sound insulation box 16 are both arranged on the top of the installation partition 12, which can optimize the internal space distribution of the device, making the space utilization more efficient and improving the space rationality of the device.

[0029] The compressor 18 is arranged in the sound insulation box 16, which can effectively isolate the noise generated during the operation of the compressor 18, reducing the noise received by the outside world and improving the sound insulation effect of the device. Multiple groups of openings are provided on the sound insulation box 16, through which users can install pipelines, enabling the device to operate stably and improving the operation reliability of the device. The two ends of the sound insulation box 16 are respectively connected to the first installation side plate 13 and the second installation side plate 14, which can enhance the stability of the sound insulation box 16, making the sound insulation box 16 not easy to shake and improving the structural stability of the device. The first installation side plate 13, the second installation side plate 14, the sound insulation box 16 and the installation top plate 19 are all provided with the first sound insulation cotton 102, through which users can further absorb the noise generated during the operation of the device, making the device operate more quietly and improving the noise reduction performance of the device. The compressor 18 is sleeved with the second sound insulation cotton 103, which can specifically reduce the noise of the compressor 18, making the user's use environment more comfortable and improving the practicality of the device. Multiple groups of the first sound insulation cotton 102 and the second sound insulation cotton 103 are all in a wave structure, through which the contact area between the first sound insulation cotton 102 and the second sound insulation cotton 103 and the sound can be increased, making the sound insulation effect more excellent and improving the sound insulation efficiency of the device.

[0030] An intake pipe 104 and an exhaust pipe 105 are respectively arranged on the compressor 18. The intake pipe 104 and the exhaust pipe 105 can ensure the smooth inlet and outlet of the refrigerant, enabling the compression operation of the compressor 18 to proceed normally, improving the working efficiency of the compressor 18. The user can connect one end of the expansion valve 101 to the evaporator 17 through a pipeline to achieve precise flow control of the refrigerant, enabling the device to be adjusted according to different working conditions and improving the adaptability of the device. By connecting one end of the evaporator 17 to the intake pipe 104 through a pipeline, a complete circulation loop can be formed, enabling efficient heat exchange and enhancing the heating performance of the device. In the present invention, the main unit is separated from the water tank 20, making this device different from the conventional pairing scheme of the main unit and the water tank 20 in the market. In the conventional scheme, when the heat pump main unit is used in combination with a water tank 20 with a capacity of less than 150L, the average static heating calorific value for raising the temperature of the 0°C circulating water from 15°C to 55°C is 1kW. When the existing heat pump main unit is used in combination with a water tank 20 with a capacity of 200L - 300L, 1.5kW - 2kW is required. However, the present invention adopts a scheme of a small main unit paired with a relatively large water tank 20, separating the heating structure from the heat conduction structure and reducing the volume of the main unit. When the device heats the 0°C circulating water from 15°C to 55°C statically with the heat pump main unit paired with a water tank 20 with a capacity of 150L - 250L, the required average heating calorific value is 0.5kW - 0.7kW. This enables the relatively large water tank 20 to meet the hot water usage needs of the user during the day and can use the time when the user is sleeping and resting at night to heat the water in the water tank 20, thereby meeting the heating requirements of the user for one day. Moreover, the present invention has a low-noise structure and will not affect the rest of the user. In addition, due to the reduction in volume, the device can be placed indoors for operation, enabling the heat pump to operate stably and reliably for a long time in the high-efficiency interval of the heat pump system within a room temperature of 7°C - 35°C, improving the operating efficiency of the device.

[0031] Radiating louvers 106 are integrally formed on both the first mounting side plate 13 and the second mounting side plate 14 and the mounting top plate 19. Multiple groups of radiating louvers 106 can effectively enhance the heat dissipation effect of the device, enabling the heat inside the device to be dissipated in a timely manner and improving the operating stability of the device. Among them, multiple groups of radiating louvers 106 located on the mounting top plate 19 are evenly arranged in sequence along the horizontal direction, and multiple groups of radiating louvers 106 located on the first mounting side plate 13 and the second mounting side plate 14 are evenly arranged in sequence along the vertical direction to ensure the uniformity and efficiency of heat dissipation, enabling the heat of each part inside the device to be effectively dissipated and improving the heat dissipation efficiency of the device. The controller 15 is electrically connected to the compressor 18 and can achieve the control of the compressor 18, enabling the compressor 18 to operate according to actual needs and improving the intelligent control level of the device.

[0032] The specific usage method and function of this embodiment:

[0033] In actual use, first, according to the internal dimensions of the wardrobe, the installation base plate 11 is fixed on the load-bearing beam at the bottom of the wardrobe. Then, functional partitions are made by installing partition plates 12, and in the slots opened in them, pre-assembled parts are arranged. The first installation side plate 13 and the second installation side plate 14 are installed on both sides of the installation base plate 11 by using bolts and positioning holes. When maintenance is required, only one side of the side plate needs to be disassembled to repair the internal parts. The installation top plate 19 at the top realizes concealed air circulation through the original ventilation opening of the wardrobe. When the user has a hot water demand, the controller 15 receives the instruction and starts the compressor 18 to drive the refrigerant cycle. Air enters the device from the wardrobe ventilation opening, successively passes through the evaporator 17 to absorb the ambient heat, the compressor 18 to increase the pressure and temperature, completes condensation and heat release in the sound insulation box 16, and then passes through the expansion valve 101 to throttle and reduce the pressure, forming a complete heating cycle. Two groups of fans 23 in the heat collection assembly operate to generate a directional air flow, cooperate with the evaporator 17 to realize latent heat recovery, and improve the heating efficiency. During operation, the sound insulation box 16, the first sound insulation cotton 102 inside and the second sound insulation cotton 103 on the compressor 18 effectively reduce noise, providing a quiet environment for the user. Multiple groups of heat dissipation louvers 106 ensure uniform and efficient heat dissipation inside the device, maintaining the stable operation of the device. The host of the present invention has a small volume due to the split structure. When used in conjunction with a larger water tank 20, the water tank 20 can meet the user's hot water demand during the day, and heat the water in the water tank 20 during the rest time at night to meet the heating demand for one day. At the same time, the low-noise structure of the device does not affect rest, and its small volume enables it to operate indoors, and the heat pump system can operate stably and reliably for a long time in the high-efficiency range at a room temperature of 7°C - 35°C.

[0034] The foregoing has shown and described the basic principles, main features and advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments.
