Furthermore, the air supply structure is also provided with an exhaust pipeline which is connected with the air outlet 9 in a matching way, and the air at the air outlet 9 is further exhausted outdoors.
Through adopting above-mentioned scheme, fan housing 1021 sets up in the port department of air intake 6, has certain wind effect of gathering, can assist the flabellum to follow 6 convulsions of air intake to a certain extent, and in addition, circular shape fan housing 1021 can reduce the resistance of air current, reduces the energy consumption.
As an embodiment, as shown in fig. 1 to 5, an air supply structure of a heat pump water heater includes a fan 10 and a casing 12, where the casing 12 includes a first casing 1 and a second casing 2. The first casing 1 is provided with a first connecting portion 18, the second casing 2 is provided with a second connecting portion 28, wherein there are multiple sets of connecting portions provided on the first casing 1 and the second casing 2.
Preferably, the connecting portions are four groups, and the first connecting portion 18 and the second connecting portion 28 are respectively disposed at one end of the connection between the first casing 1 and the second casing 2, and are connected by plugging, and the connecting portions include a protrusion and a groove. The first connecting part 18 is a groove structure arranged on the end face of the opening end of the first cavity 13, a lug structure arranged on the first air guide concave part 17 at two sides of the first cavity 13, and a lug structure arranged in the middle of the outer wall of the first shell 1; the second connecting portion 28 is matched with the first connecting portion 18 in a position opposite to each other, and is a projection structure provided on an end surface of the open end of the second cavity 23, a groove structure provided on the second air guiding recess 27 located on both sides of the second cavity 23, and a groove structure provided on the middle portion of the outer wall of the second casing 2.
Furthermore, the cross sections of the open end of the first concave cavity 13 and the open end of the second concave cavity 23 are respectively coated with sealant, and after the first shell 1 and the second shell 2 are buckled and connected to form the complete enclosure 12, the air in the air cavity is further prevented from overflowing from the joint of the open end of the first concave cavity 13 and the open end of the second concave cavity 23, and the sealing performance of the enclosure 12 is further prevented from being influenced.
By adopting the above scheme, four groups of connecting parts are provided, which is only an embodiment, the invention does not limit the number of the connecting parts, and the connecting parts are respectively arranged at four positions on the left, middle and right of the first shell 1 and the second shell 2 and on the end surfaces of the open ends of the two cavities, so that the two connecting parts can firmly connect the first shell 1 and the second shell 2, a complete shell 12 structure is formed, and the stability and the tightness of the shell 12 are ensured.
In addition, the first connecting portion 18 and the second connecting portion 28 are configured as a protrusion and a groove, when the first casing 1 and the second casing 2 are connected, only the protrusion needs to be correspondingly inserted into the groove matched with the protrusion, so that the connection effect of the first casing 1 and the second casing 2 is ensured, and the dismounting and the mounting are convenient.
As an embodiment, as shown in fig. 6, an installation structure of an air supply structure of a heat pump water heater includes the air supply structure, a heat exchanger 14 and a fixing base 11 for fixing the air supply structure. The air supply structure comprises a machine shell 12, wherein the machine shell 12 comprises a second shell 2 arranged on a fixed seat 11, and the second shell 2 is preferably clamped or inserted in a mode of being connected with the fixed seat 11. And a connecting part used for being connected with the fixed seat 11 is arranged on the bottom wall of the second shell 2, and the connecting part is preferably a convex-concave matching connecting structure of a convex block and a concave groove.
As an embodiment, as shown in fig. 1 to 5, an air supply structure of a heat pump water heater includes a casing 12, where the casing 12 includes a first casing 1 and a second casing 2, and the first casing 1 and the second casing 2 are directly formed by foaming a polypropylene plastic foam material (EPP material for short). The shape on the outer wall of the casing 12 is matched with the structure of the inner wall of the casing for covering the heat pump system, so that when the casing covers the heat pump system, perfect buckling cannot be realized due to the fact that the shape of the outer wall of the casing 12 is not matched.
Because when the housing 12 is manufactured, the components need to be combined and connected, the manufacturing process becomes complicated, and the connection relationship between the components of the housing 12 also has the risk of loosening and disjointing, thereby reducing the stability of the housing 12. On the other hand, because some types of heat pump water heaters have higher requirements on the heat preservation and noise reduction functions of the casing 12 of the air supply structure, after the casing 12 is connected and processed by using the connecting part, heat preservation cotton needs to be adhered to the inner side wall of the casing 12 to insulate heat and reduce noise, the heat preservation cotton is poor in heat insulation and noise reduction effects, the heat preservation cotton is easy to fall off in the installation process, the assembly process among all components is complex, the efficiency is low, and the whole production cycle is influenced.
By adopting the proposal, the first shell 1 and the second shell 2 of the casing 12 are formed by directly foaming polypropylene plastic foaming materials, thereby avoiding complex assembly between parts, simplifying the assembly process of the air supply structure, improving the efficiency of batch production, saving related connecting parts for connection, simplifying the production process of the air supply structure,
on the other hand, the polypropylene plastic foam material (EPP material for short) has good heat preservation and noise reduction effects, and can effectively separate the internal environment and the external environment of the air cavity, thereby preventing the air in the air cavity from exchanging heat with the indoor air to cause the temperature of the indoor environment to decrease, and preventing the noise generated by the fan 10 from causing adverse effects on users. In addition, the air supply structure has lighter weight, is convenient to install and transport, and effectively reduces the weight of the whole machine. The defects that in the prior art, heat insulation cotton is used for adhering the inner wall of the shell 12 for heat insulation and noise reduction, the effect is poor, the adhering process is easy to fall off, the product quality is not easy to guarantee, and the like are overcome.
The above embodiments are only preferred embodiments of the present invention, and not intended to limit the present invention in any way, and although the present invention has been disclosed by the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications to the equivalent embodiments by using the technical contents disclosed above without departing from the technical scope of the present invention, and the embodiments in the above embodiments can be further combined or replaced, but any simple modification, equivalent change and modification made to the above embodiments according to the technical spirit of the present invention still fall within the technical scope of the present invention.
