[0029] For better understanding and implementation, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0030] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0032] Refer to Figures 1 to 7The utility model discloses an air energy wall-mounted boiler, including a water tank 11, a heat exchange component, a heating element 13 and a water pump 14. The water tank 11 is provided with a water inlet 111 and a water outlet 112. The heat exchange component includes a heat exchange element 12, an evaporator 21 and a compressor 22. The heat exchange element 12 has a first flow channel and a second flow channel. The first flow channel has a first interface 1211 and a second interface 1212. The first interface 1211 is communicated with the water outlet 112, and a guide pipe 15 is connected to the second interface 1212. In addition, one end of the compressor 22 is communicated with one end of the second flow channel, and the other end of the second flow channel is communicated with one end of the evaporator 21, and the other end of the evaporator 21 is communicated with the other end of the compressor 22. The second flow channel exchanges heat with the first flow channel; the heating element 13 is connected to the guide pipe 15 and is used for heating, and the water pump 14 is used to drive the water to circulate.

[0033] On the basis of the above structure, during assembly, the water inlet 111 of the water tank 11 is connected to the external water circuit, and the water outlet 112 is connected to the first flow channel of the heat exchange element 12, and then the second flow channel of the heat exchange element 12 is connected to the compressor 22 and the evaporator 21 respectively, so that the heat exchange medium (such as refrigerant) in the compressor 22 and the evaporator 21 can be introduced or exported into the second flow channel, so that the heat exchange medium in the second flow channel exchanges heat with the water in the first flow channel. In this way, the water introduced into the first flow channel can be heated. Thereafter, when the water in the first flow channel is heated, it can be exported through the guide pipe 15 at the second interface 1212. Since the guide pipe 15 is provided with a heating element 13, the heated water in the first flow channel can be discharged to the guide pipe 15 and heated again.

[0034] Specifically, when in use, the heat exchange medium in the evaporator 21 absorbs heat from the air during evaporation and gasification, and is converted into a gaseous heat exchange medium and then enters the compressor 22. Thereafter, the heat exchange medium entering the compressor 22 is compressed into a high-temperature and high-pressure gas and enters the second flow channel of the heat exchange element 12, exchanges heat with the water in the first flow channel, and releases heat to the water, so that the temperature of the water in the first flow channel increases. The water with increased temperature flows into the flow guide pipe 15 through the second interface 1212 and is discharged for external use. At the same time, the heat exchange medium is cooled and condensed into liquid after exchanging heat with the water. The heat exchange medium condensed into liquid re-enters the evaporator 21 after being depressurized, and a new round of circulation begins.

[0035] In addition, since a heating element 13 is also provided at the guide pipe 15, when the ambient temperature is too low, the heating element 13 can be started at the same time to heat the guide pipe 15, so that the hot water flowing in the guide pipe 15 is reheated, thereby increasing the temperature of the hot water in the guide pipe 15 and ensuring that the water temperature discharged through the guide pipe 15 is hot enough for external use, thereby indirectly improving the user experience.

[0036] It should be noted that a temperature detection device may also be provided at the specific diversion pipe 15 to detect the temperature of the water in the diversion pipe 15, so that the user can turn on the heating element 13 in real time according to needs, ensuring that the temperature of the water discharged through the diversion pipe 15 can meet the user's water use requirements.

[0037] More specifically, the diversion pipe 15 can be made of a heat-conducting material, and the heating element 13 (such as a PTC heater or an infrared heater) is wrapped or attached to the outer periphery of the diversion pipe 15 for direct heating, or a heating wire can be provided inside the diversion pipe 15 to directly heat the water source inside the diversion pipe 15; of course, it can also be that the pipeline of an electric heating pipe or a PTC heater is directly formed as part or all of the diversion pipe 15, so that the water can be heated when passing through the inside of the pipeline, and it can be specifically set according to actual needs.

[0038] In addition, the heat exchange element 12 can be selected from a heat exchange sleeve, a fixed tube sheet heat exchanger, a floating head heat exchanger, etc. When a heat exchange sleeve is used, the flow channels inside the two sleeves are respectively formed as the first flow channel and the second flow channel; when a fixed tube sheet heat exchanger or a floating head heat exchanger is used, the first flow channel can be formed between the shell and the heat exchange plate or heat exchange fins, and the second flow channel can be formed by mechanical cutting inside the heat exchange plate or by arranging heat exchange tubes inside the plate, etc., so that two flow channels are formed inside.

[0039] Furthermore, the water tank 11 in this embodiment is made of a heat-conducting material, and the heat exchange element 12 is a heat exchange sleeve. Specifically, the heat exchange sleeve includes an inner tube 121 and an outer tube 122. The outer tube 122 is sleeved on the outer periphery of the inner tube 121. The first flow channel is formed in the inner tube 121, and the second flow channel is formed in the outer tube 122. The heat exchange sleeve is wound around the outer periphery of the water tank 11, and the outer tube 122 is in contact with the water tank 11.

[0040] Based on this structure, since the heat exchange sleeve is wound around the outer periphery of the water tank 11 and the water tank 11 is made of a heat-conducting material, thus, when the high-temperature and high-pressure heat exchange medium flows into the second flow channel, the heat released by the heat exchange medium in the second flow channel can not only be conducted to the water in the first flow channel, but also be synchronously conducted to the water inside the water tank 11 through the heat transfer of the heat-conducting material of the water tank 11 itself, preheating the water in the water tank 11, so that the water in the water tank 11 can be heated faster when flowing into the first flow channel, improving the heating efficiency of the whole structure.

[0041] Preferably, the water tank 11 in this embodiment can be made of a heat-conducting metal such as stainless steel, copper or nickel-chromium alloy, so that the heat transfer effect of the inner wall of the water tank 11 is better.

[0042] Further, a connector is installed at the second interface 1212. The connector is electrically connected to the second interface 1212. One end of the heating element 13 is in communication with the connector, and the other end of the heating element 13 is in communication with the diversion pipe 15. The heating element 13 has a diversion channel 131. The second interface 1212 is used to conduct water to the diversion channel 131, and the diversion channel 131 is used to guide the water flow to the diversion pipe 15 for discharge.

[0043] Specifically, the heating element 13 in this embodiment can be a heating pipe or a PTC heater. A diversion channel 131 is formed through the internal pipeline thereof, and it is in communication with the second interface 1212 through the connector. The other end of the heating element 13 away from the connector is in communication with the diversion pipe 15, so that the warm water discharged from the first flow channel can be reheated after flowing into the diversion channel 131, and then discharged through the diversion pipe 15 after being reheated. In this way, even if the ambient temperature is too low, the temperature of the water discharged through the diversion pipe 15 will not be too low, ensuring that the temperature of the water is suitable for user use.

[0044] Preferably, the heating element 13 in this embodiment is a PTC heater, and the diversion channel 131 is formed inside the heat conduction pipe of the PTC heater. Compared with other heaters, the PTC heater uses a PTC ceramic heating element, which has a positive temperature coefficient characteristic, that is, as the temperature increases, the resistance value increases, thereby automatically limiting the current and heat generation. This characteristic enables the PTC heater to automatically reduce the power after reaching the set temperature, reducing unnecessary energy consumption and achieving an energy-saving effect.

[0045] In addition, the PTC heater can quickly convert electrical energy into heat energy, and has a high thermal efficiency, reducing energy waste.

[0046] More specifically, since the heating element will release heat during the heating process, in order to prevent the heat from being transferred to other components and affecting the use, in this embodiment, a heat insulation sleeve 132 is also sleeved on the outer periphery of the heating element to isolate the heat on the outer periphery of the heating element through the heat insulation sleeve 132, reducing the risk of heat conduction to other components and affecting the use of other components.

[0047] Further, a blower 23 is also included. Specifically, the blower 23 is located on one side of the evaporator 21 and is used to direct the air flow to blow onto the evaporator 21.

[0048] Specifically, when the blower 23 operates, it guides the cold air outside to blow onto the surface of the evaporator 21, thereby accelerating the heat exchange process of the heat exchange medium inside the evaporator 21. Due to the accelerating effect of the blower 23, the air flow rate on the surface of the evaporator 21 is increased, which helps to reduce the temperature difference on the surface of the evaporator 21, improve the heat exchange efficiency, and at the same time, it can also effectively prevent frosting or icing on the surface of the evaporator 21, ensuring the normal operation of the system.

[0049] Preferably, the blower 23 can be a suction fan, a centrifugal fan, or the like.

[0050] More specifically, it further includes a throttle valve 24. During assembly, the throttle valve 24 is respectively connected to the evaporator 21 and the heat exchanger 12. By adjusting the opening degree of the throttle valve 24, the flow rate of the heat exchange medium can be controlled to ensure that the heat exchange medium flows into the evaporator 21 at an appropriate flow rate, thereby meeting the heat load requirements of the evaporator 21 and protecting the evaporator 21 from damage.

[0051] In addition, by restricting the flow rate of the heat exchange medium, the pressure of the heat exchange medium in the evaporator 21 can be reduced, enabling it to evaporate and absorb heat at a lower pressure.

[0052] Preferably, the throttle valve 24 can be an electronic expansion valve, a thermal expansion valve, or the like.

[0053] Furthermore, it includes a first housing 10 and a second housing 20. During assembly, the heat exchanger 12, the water tank 11, and the water pump 14 are installed in the first housing 10, while the evaporator 21, the compressor 22, the blower, and the throttle valve 24, etc. are installed in the second housing 20 to protect the equipment from damage; of course, the compressor 22 and the throttle valve 24 can also be installed in the first housing 10, which can be specifically set according to the size of the internal space of the housing.

[0054] More specifically, when the evaporator 21, the compressor 22, the blower, and the throttle valve 24 in this embodiment are all installed in the second housing 20, a partition plate 25 is provided in the second housing 20. The second housing 20 is divided into two chambers by the partition plate 25. During assembly, the blower and the evaporator 21 are installed in one chamber, which can ensure that the strong air flow generated by the blower 23 directly acts on the surface of the evaporator 21, improving the heat exchange efficiency of the evaporator 21; and the compressor 22 and the throttle valve 24 are installed in the other chamber to isolate them from the evaporator 21, avoiding the heat energy or cold energy generated during the heat exchange process of the evaporator 21 from affecting the use of the compressor 22 and the throttle valve 24.

[0055] Furthermore, a first water pipe 16 is provided at the water inlet 111 of the water tank 11, and a second water pipe 17 is provided at the water outlet 112. A through-hole is provided on the first housing 10. During assembly, the first water pipe 16 is passed through the through-hole to be connected to an external water circuit, and the second water pipe 17 is connected to the first flow channel. In this way, the external water can be introduced into the water tank 11 through the first water pipe 16 and the water can be discharged into the first flow channel through the second water pipe 17; and the water pump 14 can be connected to the first water pipe 16 or the second water pipe 17 to drive the water in the water tank 11 to be circulated and introduced or discharged into multiple pipelines.

[0056] As a preference, the water pump 14 in this embodiment is connected to the second water pipe 17.

[0057] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
