[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1 to 2As shown, an embodiment of this utility model provides an air conditioning water heater device, including a refrigerant circulation pipeline 10, a compressor 20, an indoor heat exchanger 30, an outdoor heat exchanger 40, a water circulation pipeline 50, and a water tank 60. The compressor 20, the indoor heat exchanger 30, and the outdoor heat exchanger 40 are all connected to the refrigerant circulation pipeline 10. The water tank 60 and the outdoor heat exchanger 40 are arranged at intervals. The water tank 60 is connected to the water circulation pipeline 50. The water circulation pipeline 50 is connected to the outdoor heat exchanger 40. The water in the water circulation pipeline 50 exchanges heat with the refrigerant in the outdoor heat exchanger 40.

[0024] In this embodiment, the water in the water tank 60 can directly exchange heat with the outdoor heat exchanger 40 through the water circulation pipe 50, eliminating the need for a separate heat exchanger and refrigerant connection pipe for the hot water function. This not only shortens the refrigerant flow path and simplifies the structure of the entire device, but also reduces the amount of refrigerant used, thereby reducing the manufacturing and maintenance costs of the entire device. Furthermore, it reduces potential refrigerant leak points and improves the safety and operating efficiency of the entire device.

[0025] like Figure 2 As shown, the outdoor heat exchanger 40 includes a first heat exchanger 41 and a second heat exchanger 42 that are interconnected, with the water circulation pipe 50 passing through the first heat exchanger 41. By dividing the outdoor heat exchanger 40 into a first heat exchanger 41 for heat exchange with the water supply tank 60 and a second heat exchanger 42 for heat exchange with the external environment, and by enabling the first heat exchanger 41 and the second heat exchanger 42 to be activated separately or jointly in different operating modes, a reasonable division of labor for hot water and air conditioning heat exchange is achieved, avoiding thermal interference between different modes. This also simplifies the pipe layout, making the overall internal space layout of the device more rational. Furthermore, this design allows for the removal or inspection of only individual heat exchangers when maintenance is required, without affecting the operation of other parts, thus improving the maintainability of the device.

[0026] like Figure 1 As shown, the heat exchange tubes through which the refrigerant flows in the first heat exchanger 41 have a meandering structure. One end of the first heat exchanger 41 is connected to the compressor 20, enabling the use of the heat from the high-temperature refrigerant output by the compressor 20 to heat water, thereby improving the overall energy efficiency of the device and reducing energy consumption. Designing the heat exchange tubes through which the refrigerant flows in the first heat exchanger 41 as a meandering structure increases the length of the refrigerant's flow path within the first heat exchanger 41, increasing the contact area with the water in the water tank 60; it also prolongs the refrigerant's flow time within the first heat exchanger 41, improving the heat exchange efficiency per unit time. One end of the second heat exchanger 42 is connected to the indoor heat exchanger 30, ensuring that the refrigerant can exchange heat with the indoor environment.

[0027] like Figure 1As shown, the air conditioning water heater device also includes an outdoor fan 70, which blows air onto the second heat exchanger 42, thereby accelerating the air circulation of the second heat exchanger 42, improving the air-cooled heat dissipation efficiency, and thus improving the heat exchange efficiency of the air conditioner.

[0028] like Figure 1 As shown, the air conditioning water heater device also includes a connecting pipe 81 and a first electronic expansion valve 91. The two ends of the connecting pipe 81 are connected to the first heat exchanger 41 and the second heat exchanger 42, respectively. The first electronic expansion valve 91 is installed on the connecting pipe 81, thus enabling a direct connection between the first heat exchanger 41 and the second heat exchanger 42, allowing refrigerant to flow between them. Furthermore, the first electronic expansion valve 91, installed on the connecting pipe 81, can adjust the amount of refrigerant flowing through the connecting pipe 81 according to the operating mode.

[0029] like Figure 1 As shown, the air conditioning water heater device also includes a second electronic expansion valve 92, which is installed in the refrigerant circulation pipe 10. The air conditioning water heater device has an indoor cooling and heat recovery mode. In the indoor cooling and heat recovery mode, the first electronic expansion valve 91 is throttled, the second electronic expansion valve 92 is fully open, the indoor heat exchanger 30 cools the indoor environment, the water in the water circulation pipe 50 circulates, and the water circulation pipe 50 recovers the heat of the refrigerant in the first heat exchanger 41.

[0030] In this embodiment, under indoor cooling and heat recovery mode, the high-temperature, high-pressure refrigerant output from the compressor 20 is first transported to the first heat exchanger 41 via the refrigerant circulation pipeline 10. In the first heat exchanger 41, it exchanges heat with the water in the water tank 60 for initial cooling and heating of the hot water. Then, it is transported to the second heat exchanger 42 via the connecting pipe 81. At this point, the refrigerant passes through the first electronic expansion valve 91, which throttles the refrigerant flow before it enters the refrigerant circulation pipeline 10 and is transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipeline 10 is fully open, ensuring cooling of the indoor environment. This arrangement ensures that the heat from the refrigerant is not wasted but is used to heat the hot water, improving the overall energy efficiency of the device and saving energy.

[0031] like Figure 1As shown, the air conditioning water heater also has an indoor cooling mode, an indoor heating mode, and a hot water mode. In the indoor cooling mode, the first electronic expansion valve 91 is fully open, the second electronic expansion valve 92 is throttled, and the indoor heat exchanger 30 cools the indoor environment. In the indoor heating mode, the first electronic expansion valve 91 is fully open, the second electronic expansion valve 92 is throttled, and the indoor heat exchanger 30 heats the indoor environment. In the hot water mode, the first electronic expansion valve 91 is throttled, the second electronic expansion valve 92 is fully open, water flows in the water circulation pipe 50, and the first heat exchanger 41 heats the hot water in the water tank 60.

[0032] In this embodiment, the air conditioning water heater also has an indoor cooling mode, an indoor heating mode, and a hot water mode. In the indoor cooling mode, the high-temperature and high-pressure refrigerant output from the compressor 20 is first transported to the second heat exchanger 42 through the refrigerant circulation pipe 10 and the connecting pipe 81. At this time, the first heat exchanger 41 is not working, the water circulation pipe 50 is not connected to the first heat exchanger 41, and the first electronic expansion valve 91 is fully open, allowing the refrigerant to exchange heat with the outdoor environment in the second heat exchanger 42. Then, it enters the refrigerant circulation pipe 10 and is transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipe 10 throttles the flow, thus cooling the indoor environment.

[0033] In indoor heating mode, the high-temperature and high-pressure refrigerant output from the compressor 20 is first delivered to the indoor heat exchanger 30 through the refrigerant circulation pipeline 10 to heat the indoor environment. Then, it enters the refrigerant circulation pipeline 10 and is delivered to the second heat exchanger 42. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipeline 10 throttles the flow, the first heat exchanger 41 does not work, the water circulation pipeline 50 is not connected to the first heat exchanger 41, and the first electronic expansion valve 91 is fully open, so that the refrigerant can flow back to the compressor 20 through the refrigerant circulation pipeline 10 and the connecting pipe 81.

[0034] In hot water mode, the high-temperature and high-pressure refrigerant output from the compressor 20 is first transported to the first heat exchanger 41 through the refrigerant circulation pipe 10. In the first heat exchanger 41, it exchanges heat with the water in the water tank 60 to heat the hot water. Then, it is transported to the second heat exchanger 42 through the connecting pipe 81. At this time, the refrigerant will pass through the first electronic expansion valve 91, which throttles the refrigerant. It then enters the refrigerant circulation pipe 10 and is transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipe 10 is fully open, allowing the refrigerant to flow back to the compressor 20 through the refrigerant circulation pipe 10.

[0035] The above settings enable the air conditioner water heater to switch between different modes without changing the hardware structure, thus improving the control flexibility of the device and the user experience.

[0036] like Figure 1As shown, the air conditioning water heater device also includes a water pump 82, which is installed in the water circulation pipe 50. The water pump 82 is used to control the water flow in the water circulation pipe 50, ensuring that the water flows continuously in the water circulation pipe 50 and the first heat exchanger 41 and exchanges heat effectively with the refrigerant, avoiding the problem of water stagnation or low flow rate, which would lead to a decrease in heat exchange efficiency.

[0037] like Figure 1 As shown, the water tank 60 has an inlet and an outlet on both sides, one end of the water circulation pipe 50 is connected to the inlet of the water tank 60, and the other end of the water circulation pipe 50 is connected to the outlet of the water tank 60; or, a part of the water circulation pipe 50 is located inside the water tank 60, and the water circulation pipe 50 located inside the water tank 60 has a meandering structure.

[0038] In this embodiment, the inlet and outlet are respectively located on both sides of the water tank 60, and the water circulation pipe 50 is connected to the inlet and outlet to ensure the flow direction and flow rate of water in the water tank 60, thereby promoting water circulation and heat transfer efficiency.

[0039] Alternatively, a portion of the water circulation pipe 50 can be located inside the water tank 60, employing a meandering structure. This allows the water to remain within the pipes of the water tank 60 for a longer period, increasing the contact time between the water and the heat source and effectively improving heat exchange efficiency. Simultaneously, the meandering structure allows the water to bypass a longer path, increasing the heat exchange area within the water tank 60, resulting in more thorough heat exchange between the refrigerant and the water, and enabling the water to be heated quickly to the required temperature.

[0040] like Figure 1 As shown, the refrigerant circulation pipeline 10 includes a four-way valve 11, an output pipe 12, an input pipe 13, a first branch 14, a second branch 15, a third branch 16, and a fourth branch 17. The water circulation pipeline 50 includes a fifth branch 51 and a sixth branch 52. The two ends of the output pipe 12 are connected to the outlet of the compressor 20 and the four-way valve 11, respectively. The two ends of the input pipe 13 are connected to the inlet of the compressor 20 and the four-way valve 11, respectively. The two ends of the first branch 14 are connected to the four-way valve 11 and one end of the first heat exchanger 41, respectively. The two ends of the second branch 15 are connected to... One end of the second heat exchanger 42 is connected to one end of the third branch 16, and the other end of the third branch 16 is connected to one end of the indoor heat exchanger 30. The two ends of the fourth branch 17 are connected to the other end of the indoor heat exchanger 30 and the four-way valve 11, respectively. One end of the fifth branch 51 is connected to the water tank 60, and the other end of the fifth branch 51 is connected to one end of the first heat exchanger 41. One end of the sixth branch 52 is connected to the other end of the first heat exchanger 41, and the other end of the sixth branch 52 is connected to the water tank 60. Control valves are installed on both the fifth branch 51 and the sixth branch 52.

[0041] In this embodiment, in the indoor cooling and heat recovery mode, the high-temperature and high-pressure refrigerant output from the compressor 20 enters the four-way valve 11 through the output pipe 12, and is then transported to the first heat exchanger 41 through the first branch 14. At this time, the fifth branch 51 and the sixth branch 52 are both connected to the first heat exchanger 41, so that the refrigerant exchanges heat with the water in the water tank 60 in the first heat exchanger 41, performs preliminary cooling, and realizes the heating of hot water. Then, it is transported to the second heat exchanger 42 through the connecting pipe 81. At this time, the refrigerant will pass through the first electronic expansion valve 91, which throttles the refrigerant, and then enters the second branch 15 and the third branch 16 to be transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipe 10 is fully open to ensure that the indoor environment can be cooled. Then, it flows back to the four-way valve 11 through the fourth branch 17, and finally flows back to the compressor 20 through the input pipe 13.

[0042] In indoor cooling mode, the high-temperature and high-pressure refrigerant output from the compressor 20 enters the four-way valve 11 through the output pipe 12, and is then transported to the second heat exchanger 42 through the first branch 14 and the connecting pipe 81. At this time, the first heat exchanger 41 is not working, the fifth branch 51 and the sixth branch 52 are not connected to the first heat exchanger 41, and the first electronic expansion valve 91 is fully open, allowing the refrigerant to exchange heat with the outdoor environment in the second heat exchanger 42. Then, it enters the second branch 15 and the third branch 16 and is transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipe 10 throttles the refrigerant to cool the indoor environment. Then, it flows back to the four-way valve 11 through the fourth branch 17, and finally flows back to the compressor 20 through the input pipe 13.

[0043] In indoor heating mode, the high-temperature and high-pressure refrigerant output from the compressor 20 enters the four-way valve 11 through the output pipe 12, and is then transported to the indoor heat exchanger 30 through the fourth branch 17 to heat the indoor environment. Then, it enters the second branch 15 and the third branch 16 and is transported to the second heat exchanger 42. At this time, the second electronic expansion valve 92 throttles the flow, the first heat exchanger 41 does not work, the fifth branch 51 and the sixth branch 52 are not connected to the first heat exchanger 41, and the first electronic expansion valve 91 is fully open, so that the refrigerant can flow back to the four-way valve 11 through the first branch 14 and the connecting pipe 81, and finally flow back to the compressor 20 through the input pipe 13.

[0044] In hot water mode, the high-temperature and high-pressure refrigerant output from the compressor 20 enters the four-way valve 11 through the output pipe 12, and is then transported to the first heat exchanger 41 through the first branch 14. The fifth branch 51 and the sixth branch 52 are both connected to the first heat exchanger 41, so that the refrigerant exchanges heat with the water in the water tank 60 in the first heat exchanger 41 to heat the hot water. Then, it is transported to the second heat exchanger 42 through the connecting pipe 81. At this time, the refrigerant passes through the first electronic expansion valve 91, which throttles the refrigerant, and then enters the second branch 15 and the third branch 16 to be transported to the indoor heat exchanger 30. At this time, the second electronic expansion valve 92 on the refrigerant circulation pipe 10 is fully open, and then flows back to the four-way valve 11 through the fourth branch 17, and finally flows back to the compressor 20 through the input pipe 13.

[0045] like Figure 1 As shown, the air-conditioning water heater also includes a first temperature sensor and a second temperature sensor. The first temperature sensor is located in the indoor environment, and the second temperature sensor is located inside the water tank 60. Users can switch between different operating modes based on the information fed back by the first and second temperature sensors to ensure indoor comfort and hot water supply.
