[0031] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand this utility model and implement it. However, the embodiments are not intended to limit this utility model. In this embodiment, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0032] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0033] This embodiment provides a gas water heater with a heat pump air conditioning system, such as... Figures 1 to 2 As shown, it includes:

[0034] The outer casing 100 has a first inner cavity 110 and a second inner cavity 120 that are separated from each other. The first inner cavity 110 is provided with an air inlet 121 and an air outlet 122 to facilitate air convection in the first inner cavity 110 to achieve the purpose of cooling. The second inner cavity 120 is connected to the outside air of the outer casing 100.

[0035] The heat pump air conditioning unit 200 is disposed in the first inner cavity 110 and includes a first fan 250 and a compressor 210, a first heat exchanger 220, a throttling device 240 and a second heat exchanger 230 connected in sequence. The first fan 250 is used to promote airflow through the second heat exchanger 230 and out from the air outlet 122.

[0036] A gas water heater assembly 300 is disposed within a second inner cavity 120 and includes a combustion heating module and a water supply pipe 310. The water supply pipe 310 is connected sequentially to a first heat exchanger 220 and the combustion heating module along the water flow direction, and is used to exchange heat with the first heat exchanger 220 and the combustion heating module respectively. The combustion heating module is used to heat the water flowing through the water supply pipe 310 by generating heat after combustion. The throttling device 240 is used to regulate the flow rate and pressure of the refrigerant flowing out of the compressor 210, and can be a capillary structure or an expansion valve, etc. The first heat exchanger 220 is preferably a plate heat exchanger or a shell-and-tube heat exchanger. The plate heat exchanger is provided with a refrigerant pipe, and the water supply pipe 310 and the refrigerant pipe can be thermally coupled.

[0037] This utility model has a heat pump air conditioning component 200 installed in the first inner cavity 110, and the water supply pipe 310 of the gas water heater component 300 is connected to the first heat exchanger 220. The water in the water supply pipe 310 exchanges heat with the refrigerant in the first heat exchanger 220, thus cooling the refrigerant and expelling the heat from the second chamber to the outside. This can function as the outdoor unit in a conventional air conditioning system. After cooling, the refrigerant enters the second heat exchanger 230 and is cooled by the first fan 250 before being blown into the room from the air outlet 122. This enables the gas water heater to have a cooling function and to expel heat... The pump air conditioning component 200 and the gas water heater component 300 are integrated into the outer casing 100, realizing multi-functionality in one unit. There is no need to install an outdoor unit separately, which greatly reduces the overall size of the unit and the required installation space, and simplifies the installation process. It can solve the problem that traditional wall-mounted air conditioners or dedicated kitchen air conditioners require the installation of an outdoor unit or an exhaust pipe extending outdoors, which is inconvenient to install, takes up a lot of space, and is also costly. Moreover, when installed in small spaces such as kitchens, the power requirements are also lower. It should be noted that, understandably, the second heat exchanger 230 is also equipped with a condensate pipe 270 for draining condensate.

[0038] A gas water heater assembly 300 is installed inside the second inner cavity 120. The second inner cavity 120 is connected to the external air of the outer casing 100, thus possessing the hot water production function of a gas water heater. Furthermore, the water supply pipe 310 is connected sequentially along the water flow direction to the first heat exchanger 220 and the combustion heating module, such as... Figure 2 As shown, hot water can be produced not only by running only the combustion heating module, but also by running only the heat pump air conditioning unit 200, or by running both the combustion heating module and the heat pump air conditioning unit 200 simultaneously.

[0039] In a preferred embodiment, the water supply pipeline 310 is equipped with a circulation pump 311 and an inlet pipe 312 and an outlet pipe 313 that are interconnected. The circulation pump 311, the inlet pipe 312 and the outlet pipe 313 are components of the gas water heater zero cold water pipeline system. They share the pipeline with the zero cold water pipeline system, which saves material and installation costs. At the same time, when the heat pump air conditioning component 200 is running in the cooling function, hot water can be produced by running the circulation pump 311, thereby improving the energy conversion and utilization efficiency.

[0040] In one specific embodiment, the combustion heating module includes a combustion chamber 320, a burner 330, a third heat exchanger 340, and a flue pipe 350. The third heat exchanger 340 is connected to a water supply pipe 310. The burner 330 generates heat to heat the water flowing through the third heat exchanger 340. Both the burner 330 and the third heat exchanger 340 are located within the combustion chamber 320. One end of the flue pipe 350 is connected to the combustion chamber 320, and the other end is connected to the outdoor air. Furthermore, the third heat exchangers 340 are spaced above the burner 330. The high-temperature flue gas generated by the burner 330 heats the water flowing through the third heat exchanger 340, while the flue gas generated by combustion is discharged outdoors through the flue pipe 350. Preferably, the second heat exchanger 230 and the third heat exchanger 340 are finned heat exchangers, which can significantly improve heat exchange efficiency. A partition 130 is provided inside the outer casing 100, and the first inner cavity 110 and the second inner cavity 120 are separated by the partition 130 for heat insulation and air isolation, so as to prevent the two functional systems from interfering with each other during operation. Furthermore, the partition 130 is provided with a heat insulation layer (not shown in the figure), thereby improving the heat insulation effect.

[0041] like Figure 2 As shown, in this embodiment, when the combustion heating module and the heat pump air conditioning component 200 are running simultaneously to produce hot water, the cold water in the water supply pipe 310 first enters the first heat exchanger 220 to exchange heat with the high-temperature refrigerant discharged from the compressor 210, and then enters the third heat exchanger 340 to exchange heat with the high-temperature flue gas generated by the burner 330; the high-temperature refrigerant discharged when the compressor 210 is running exchanges heat with the cold water in the first heat exchanger 220, then passes through the throttling device 240 to cool and depressurize, and then enters the second heat exchanger 230 to absorb indoor heat, and then returns to the compressor 210 for compression and heating.

[0042] In a further preferred embodiment, the flue 350 includes an inner pipe 351 and an outer pipe 352. The outer pipe 352 is sleeved on the outside of the inner pipe 351, forming an airflow channel 360 between them. The inner pipe 351 is provided with a second fan 370. One end of the inner pipe 351 and the outer pipe 352 on the same side is used to communicate with the outside air. The other end of the inner pipe 351 is connected to the combustion chamber 320, and the other end of the outer pipe 352 is connected to the first inner cavity 110. By installing a second fan 370 in the inner pipe 351, the exhaust of flue gas in the combustion chamber 320 can be accelerated by running the second fan 370. At the same time, due to the negative pressure principle, the outdoor airflow can also be accelerated to enter the second inner cavity 120 from the airflow channel 360. When the heat pump air conditioner is working, the heat from the first heat exchanger 220 can be discharged to the outside through the inner pipe 351 through the cooperation of the water supply pipe 310 and the third heat exchanger 340. At the same time, air is drawn from the outside to reduce the refrigerant temperature. The cooling capacity of the indoor air will not be consumed for cooling, which can improve the cooling efficiency of the heat pump air conditioner.

[0043] In another preferred embodiment, the heat pump air conditioning assembly 200 further includes a four-way reversing valve 260, through which the compressor 210 is connected to the first heat exchanger 220 and the second heat exchanger 230 respectively. By adjusting the four-way reversing valve 260, the flow direction of the refrigerant discharged from the compressor 210 can be changed.

[0044] When the refrigerant comes from Figure 3 When the flow direction is shown, the chilled water mode can be operated. At this time, the high-temperature refrigerant discharged by the compressor 210 first passes through the second heat exchanger 230 to condense and cool down, and then passes through the throttling device 240 to further cool down and depressurize, becoming a low-temperature refrigerant. Then it enters the first heat exchanger 220 and exchanges heat with the water in the first heat exchanger 220, thereby cooling the water to obtain cold water.

[0045] When the refrigerant comes from Figure 4 When the air flows in the direction shown, the heating mode can also be operated. In this mode, the high-temperature refrigerant discharged by the compressor 210 can heat the air through the second heat exchanger 230, and the hot air near the second heat exchanger 230 is discharged after the first fan 250 is operated to achieve the purpose of heating. At the same time, the gas water heater assembly 300 is turned on to provide a heat source. It can heat the water flow in the water supply pipe 310 through low-load combustion operation, and the low-temperature refrigerant in the first heat exchanger 220 is heated and then flows back into the compressor 210, thereby achieving the purpose of continuous heating.
