Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to an energy-saving air source heat pump water heater. Background Technology

[0002] Air source heat pump water heaters, as a highly efficient and energy-saving hot water supply device, have been widely used in recent years. Their basic principle is to extract low-grade heat energy from the environment and convert it into high-grade heat energy for heating water through a reverse Carnot cycle.

[0003] However, the existing technology still has the following shortcomings: the compressor generates a lot of waste heat during operation (the temperature is usually 70-85℃). Traditional water heaters mostly rely on heat dissipation devices to directly release the heat into the environment, which fails to effectively recover and utilize the heat, resulting in energy waste. Especially under high temperature or high load conditions, the contradiction between the compressor's heat dissipation requirements and energy efficiency is more prominent. Therefore, this application provides an energy-saving air source heat pump water heater to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an energy-saving air source heat pump water heater to solve the existing problems.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An energy-saving air source heat pump water heater includes a heat pump body, an inlet pipe and a compressor disposed within the heat pump body; it also includes a preheating component disposed on the compressor and the inlet pipe, the preheating component including a preheating pipe, a heating pipe and a connecting pipe, the connecting pipe being used to absorb heat from the compressor and preheating cold water in the inlet pipe through the cooperation of the heating pipe and the connecting pipe.

[0007] In a preferred embodiment of this utility model, the preheating pipe, the heating pipe, and the connecting pipe are interconnected. Both the preheating pipe and the heating pipe are spiral wound pipes, and the preheating pipe is wrapped around the outer peripheral wall of the water inlet pipe, while the connecting pipe is wrapped around the outer peripheral wall of the compressor.

[0008] In a preferred embodiment of this utility model, the preheating component further includes a fixing frame, the bottom end of which is fixedly connected to a plurality of annularly arranged support plates, the bottom ends of which are fixed to the compressor; an adjusting rod is threadedly connected to the support plate, the inner end of which abuts against the heated pipe.

[0009] In a preferred embodiment of this utility model, acetone is filled into the preheating pipe, the heating pipe, and the connecting pipe. The acetone flows within the channel formed by the preheating pipe, the heating pipe, and the connecting pipe, and the height of the preheating pipe is greater than the height of the connecting pipe. An insulation layer is fitted onto the outer periphery of the connecting pipe, and a vacuum cavity is formed between the insulation layer and the connecting pipe. The inner walls of the preheating pipe and the heating pipe are both planar structures, and thermally conductive silicone grease is fixed on the planar structures.

[0010] In a preferred embodiment of this utility model, a fixing sleeve is provided on the outer peripheral side wall of the water inlet pipe, the preheating pipe is located inside the fixing sleeve, and the fixing sleeve is fixed to the outer wall of the heat pump body by bolts.

[0011] In a preferred embodiment of this utility model, the inner end of the adjusting rod is rotatably connected to a fixing clip, the fixing clip includes multiple recesses, and the recesses are in contact with the heated pipe.

[0012] Compared with the prior art, this utility model has at least the following beneficial effects:

[0013] In the above scheme, by setting up a preheating component, the preheating pipe and the heated pipe form a circulation channel through two connecting pipes. The heated pipe utilizes the heat from the compressor and transfers it to the preheating pipe through the connecting pipe, thereby preheating the water inlet pipe. This not only improves the heat dissipation of the compressor, but also preheats the cold water in the water inlet pipe, thereby reducing the load of subsequent heating operations and improving energy saving.

[0014] By setting up a fixing bracket and an adjusting rod, when the fixing bracket is moved inward by the adjusting rod, the recess on the fixing bracket contacts the outer wall of the heated pipe. On the one hand, this can clamp the heated pipe and improve its contact with the compressor housing, and on the other hand, it can keep the heated pipe and the compressor housing in close contact.

For some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0029] Generally, terms can be understood at least partly from their use in context. For example, depending at least partly on the context, the term "one or more" as used herein can be used to describe any feature, structure, or characteristic in a singular sense, or a combination of features, structures, or characteristics in a plural sense. Additionally, the term "based on" can be understood not necessarily to convey an exclusive set of factors, but rather, alternatively, depending at least partly on the context, to allow for the presence of other factors that are not necessarily explicitly described.

[0030] It is understood that the meanings of “on”, “above”, and “above” in this utility model should be interpreted in the broadest manner, such that “on” not only means “directly on” something, but also includes the meaning of being “on” something with an intervening feature or layer, and that “above” or “above” not only means “on” something, but also includes the meaning of being “on” something without an intervening feature or layer.

[0031] Furthermore, spatially related terms such as “below,” “under,” “lower,” “above,” and “upper” are used herein for convenience to describe the relationship of one element or feature to one or more other elements or features, as illustrated in the accompanying drawings.

[0032] like Figures 1 to 8 As shown, an embodiment of this utility model provides an energy-saving air source heat pump water heater, including a heat pump body 1, an inlet pipe 2 and a compressor 3 disposed within the heat pump body 1; it also includes a preheating component disposed on the compressor 3 and the inlet pipe 2. The preheating component includes a preheating pipe 4, a heating pipe 5 and a connecting pipe 6. The connecting pipe 6 is used to absorb heat from the compressor 3 and preheat the cold water in the inlet pipe 2 through the cooperation of the heating pipe 5 and the connecting pipe 6.

[0033] The preheating pipe 4, the heating pipe 5, and the connecting pipe 6 are interconnected. Both the preheating pipe 4 and the heating pipe 5 are spiral wound pipes, with the preheating pipe 4 wrapped around the outer periphery of the water inlet pipe 2 and the connecting pipe 6 wrapped around the outer periphery of the compressor 3. There are two connecting pipes 6. The preheating pipe 4 and the heating pipe 5 form a circulation channel through the two connecting pipes 6. The heat from the compressor 3 is used by the heating pipe 5 and transferred to the preheating pipe 4 through the connecting pipe 6, so that the water inlet pipe 2 is preheated. This not only improves the heat dissipation of the compressor 3, but also preheats the cold water in the water inlet pipe 2, thereby reducing the load of subsequent heating operations.

[0034] The preheating assembly also includes a fixing frame 7, with several ring-shaped support plates 8 fixedly connected to the bottom of the fixing frame 7. The bottom of the support plates 8 is fixed to the compressor 3. An adjusting rod 9 is threadedly connected to the support plate 8. The inner end of the adjusting rod 9 abuts against the heated pipe 5. The position of the adjusting rod 9 is moved by rotating it. The inner end of the adjusting rod 9 presses against the heated pipe 5, thereby adjusting the position of the heated pipe 5.

[0035] The inner end of the adjusting rod 9 is rotatably connected to a fixing clip 10. The fixing clip 10 includes multiple recesses, and the recesses abut against the heated pipe 5. When the fixing clip 10 is moved inward by the adjusting rod 9, the recesses on the fixing clip 10 contact the outer wall of the heated pipe 5. On the one hand, the heated pipe 5 can be clamped to improve its contact with the compressor 3 housing, and on the other hand, the heated pipe 5 and the compressor 3 housing are kept in close contact.

[0036] A fixing sleeve 11 is fitted on the outer periphery of the water inlet pipe 2. The preheating pipe 4 is located inside the fixing sleeve 11. The fixing sleeve 11 is fixed to the outer wall of the heat pump body 1 by bolts. The fixing sleeve 11 covers the preheating pipe 4 to improve the heat preservation capacity.

[0037] Acetone 13 is filled into the preheating pipe 4, the heating pipe 5, and the connecting pipe 6. The acetone 13 flows in the channel formed by the preheating pipe 4, the heating pipe 5, and the connecting pipe 6, and the height of the preheating pipe 4 is higher than that of the connecting pipe 6. An insulation layer 14 is fitted on the outer side wall of the connecting pipe 6, and a vacuum layer 15 is formed between the insulation layer 14 and the connecting pipe 6. The vacuum layer has a pressure of 0.1 Pa and serves to insulate heat and prevent leakage. Because acetone 13 is filled into the channel formed by the preheating pipe 4, the heating pipe 5, and the connecting pipe 6, the heat of the compressor 3 shell (70-85℃) causes the acetone at the heating pipe 5 to vaporize (boiling point 56℃). The vapor flows into the preheating pipe 4, thereby further improving the thermal efficiency and thus improving heat utilization. The vapor comes into contact with the water inlet pipe through the preheating pipe 4, thereby gradually cooling and liquefying. The liquid acetone flows back to the heating pipe 5 along the pipe wall, forming a repeated cycle.

[0038] In addition, copper particles of appropriate concentration and size can be added to the circulation channel to improve thermal conductivity.

[0039] The inner walls of both the preheating pipe 4 and the heating pipe 5 are planar structures, and thermal grease 12 is fixed on the planar structure. The planar structure can increase the contact area between the preheating pipe 4 and the water inlet pipe 2, as well as the contact area between the heating pipe 5 and the compressor 3, and the thermal grease can improve thermal conductivity.

[0040] Working principle: During use, the heat of the compressor 3 casing (70-85℃) causes the acetone at the heating pipe 5 to vaporize (boiling point 56℃). The vapor flows into the preheating pipe 4, thereby further improving thermal efficiency and heat utilization. The vapor comes into contact with the water inlet pipe through the preheating pipe 4, thereby gradually cooling down and liquefying. The liquid acetone flows back to the heating pipe 5 along the pipe wall, repeatedly forming a cycle. This not only improves the heat dissipation of the compressor 3, but also preheats the cold water in the water inlet pipe 2, thereby reducing the load of subsequent heating operations.

[0041] The position of the adjusting rod 9 is moved by rotating it, and the inner end of the adjusting rod 9 presses against the heating tube 5, thereby adjusting the position of the heating tube 5.

[0042] A fixing clip 10 is rotatably connected to the inner end of the adjusting rod 9. The fixing clip 10 includes multiple recesses, and the recesses abut against the heating pipe 5. When the fixing clip 10 is moved inward by the adjusting rod 9, the recesses on the fixing clip 10 contact the outer wall of the heating pipe 5. This can, on the one hand, clamp the heating pipe 5, improve its contact with the compressor 3 housing, and on the other hand, keep the heating pipe 5 and the compressor 3 housing in close contact.

[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
