[0037] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, and are used only for explaining the present application, and cannot be understood as a limitation of the present application.

[0038] In the related art, in order to achieve the heat preservation effect, the air duct assembly in the heat pump equipment is usually made of foam material, and limited by the size of the heat pump equipment, the air duct assembly must be controlled at the minimum forming thickness, and the minimum forming thickness of the foam is about 5mm. This thickness is difficult to meet the use requirements of the air duct assembly. For example, the air duct assembly often appears cracking or breaking during the assembly process or after a long use time.

[0039] Based on this, referring to Figure 1 and Figure 2As shown, the air duct assembly 1000 provided by the embodiment of the utility model, the air duct assembly 1000 includes volute 100, cover plate 200 and reinforcing structure 300, volute 100 is formed with air duct 110, one side of volute 100 is equipped with opening 111, opening 111 is used for fan 500 to enter or remove air duct 110, volute 100 is also equipped with air outlet 112 that communicates with air duct 110, cover plate 200 is covered and is located in opening 111, also can be understood as volute 100 and cover plate 200 between the above-mentioned air duct 110 is limited, cover plate 200 is equipped with air inlet 210 that communicates with air duct 110, in some embodiments, air outlet 112 is located at the upper end of volute 100, air outlet 112 is limited by volute 100 and cover plate 200, opening 111 is located at the side of volute 100 along the horizontal direction, cover plate 200 is vertically arranged, fan 500 can enter or remove air duct 110 through opening 111.Cover plate 200 is equipped with clamping groove 260 to the side of volute 100, clamping groove 260 is used for cooperating with the side of volute 100.Cover plate 200 and volute 100 are foam pieces, and the thermal conductivity coefficient is low, which can play a heat preservation effect.

[0040] Referring to Figure 2 As shown, reinforcing structure 300 includes first reinforcing member 310, first reinforcing member 310 can be arranged on at least one side of cover plate 200, thereby playing a protective effect on the side of cover plate 200, for example, first reinforcing member 310 is configured as C-shaped or U-shaped, when cover plate 200 is square, first reinforcing member 310 is arranged on at least one side of first reinforcing member 310, the number of first reinforcing member 310 can be multiple, and multiple first reinforcing member 310 are arranged on multiple sides of cover plate 200. When cover plate 200 is circular, first reinforcing member 310 can also extend along the circumferential edge of cover plate 200 to form an arc, and first reinforcing member 310 is wrapped on the outer edge of cover plate 200. In other embodiments, first reinforcing member 310 can also be configured as a flat plate structure, and first reinforcing member 310 can be arranged on the side of cover plate 200 away from volute 100, thereby playing a protective effect on the surface of cover plate 200.

[0041] It should be noted that the rigidity of the reinforcing structure 300 is greater than the rigidity of the volute 100 and the cover plate 200, that is, the structural strength of the reinforcing structure 300 is greater, so as to play a protective role on the cover plate 200. When the cover plate 200 is subjected to a bending force or an impact force, the reinforcing structure 300 can provide support and protection effect, so that the cover plate 200 is not easy to bend and break, thereby playing a protective role on the cover plate 200. It should be noted that the rigidity here can be one of the hardness indicators such as Brinell hardness, Rockwell hardness, Vickers hardness, Knoop hardness or Mohs hardness. As long as one of the hardness indicators of the reinforcing structure 300 is greater than the corresponding hardness indicator of the cover plate 200, it can be considered that the rigidity of the reinforcing structure 300 is greater than the rigidity of the cover plate 200. It should be noted that the description of the rigidity in the following embodiments can be referred to in this embodiment, and can be any one of the above hardness indicators, and thus will not be repeated. It can be understood that the reinforcing structure 300 can be provided as a plastic part or a metal part, such as a sheet metal part, and the plastic part has good heat preservation effect, and the sheet metal part has greater rigidity and better protection effect, but is not limited to this. The reinforcing structure 300 can also be provided as other materials, as long as the structural strength of the reinforcing structure 300 is greater than that of the foam.

[0042] It should be noted that in the process of manufacturing the cover plate 200, the first reinforcing part 310 can be placed on the forming mold of the cover plate 200, so that the first reinforcing part 310 is integrally formed with the cover plate 200, and the first reinforcing part 310 is molded together with the cover plate 200. The cover plate 200 will be tightly pressed against the first reinforcing part 310 during foaming and expansion, thereby fixing the position of the first reinforcing part 310. Alternatively, the first reinforcing part 310 can be assembled to the cover plate 200 after the cover plate 200 is manufactured. The first reinforcing part 310 is clamped to the side edge of the cover plate 200 by clamping. In other embodiments, the first reinforcing part 310 and the cover plate 200 can be fixed together by glue.

[0043] In the process of assembling the air duct assembly 1000, the fan 500 is first installed in the air duct 110, and then the cover plate 200 is covered on the opening 111 of the volute 100. The clamping groove 260 of the cover plate 200 is clamped with the side edge of the volute 100, so as to fix the cover plate 200. Since the rigidity of the first reinforcing part 310 is greater, the structural strength of the first reinforcing part 310 is greater, and the first reinforcing part 310 is not easy to bend, the first reinforcing part 310 plays a protective role. In the process of assembling the cover plate 200 or after the air duct assembly 1000 is used for a long time, the cover plate 200 is not easy to crack or break.

[0044] Reference Figure 2As shown, in some embodiments, the first reinforcing member 310 is wrapped around the side edge of the cover plate 200, and the first reinforcing member 310 can be configured in a U shape so as to wrap the cover plate 200 well. Specifically, referring to Figure 9 As shown, the first reinforcing member 310 is provided with a first flange 311 and a second flange 312 on two sides respectively, and the first flange 311 and the second flange 312 are oppositely arranged. The first reinforcing member 310 can be a sheet metal part, and the first flange 311 and the second flange 312 can be processed by a bending process. The first flange 311 and the second flange 312 respectively abut against the two sides of the cover plate 200 opposite to each other. The first reinforcing member 310 clamps the cover plate 200 through the first flange 311 and the second flange 312, so as to fix the first reinforcing member 310 on the cover plate 200.

[0045] Referring to Figure 2 and Figure 7 As shown, in some embodiments, the reinforcing structure 300 further comprises a second reinforcing member 320, which is wrapped around the side of the cover plate 200 away from the volute 100. Referring to Figure 10 and Figure 11 As shown, the second reinforcing member 320 can be configured in an L shape, and the second reinforcing member 320 is provided with a third flange 321 embedded in the cover plate 200. Specifically, the second reinforcing member 320 can be placed on a forming mold of the cover plate 200 during the manufacturing process of the cover plate 200, so that the second reinforcing member 320 is integrally formed with the cover plate 200, and the second reinforcing member 320 is taken out of the mold together with the cover plate 200. During the foaming expansion process of the cover plate 200, the third flange 321 is surrounded by the cover plate 200, so as to fix the position of the second reinforcing member 320. Alternatively, a groove can be left on the surface of the side of the cover plate 200 away from the volute 100, and the third flange 321 is inserted into the groove after the cover plate 200 is manufactured.

[0046] It should be noted that the second reinforcing member 320 is arranged on the side of the cover plate 200 away from the volute 100 because the side of the cover plate 200 away from the volute 100 is relatively flat, so that the second reinforcing member 320 can be better attached to the surface of the cover plate 200. Since the side of the cover plate 200 close to the volute 100 is connected to the volute 100 through the clamping groove 260, the surface with the clamping groove 260 is relatively not flat enough, which hinders the arrangement of the second reinforcing member 320.

[0047] In addition, compared with the first reinforcing member 310, the second reinforcing member 320 covers a larger surface area of the cover plate 200, and can protect the surface of the cover plate 200 more comprehensively. The first reinforcing member 310 mainly protects the side edge of the cover plate 200, and the first reinforcing member 310 and the second reinforcing member 320 are used in cooperation to effectively improve the protection effect of the cover plate 200.

[0048] In some embodiments, referring toFigure 2 and Figure 3 As shown, the first reinforcement 310 is arranged vertically, and the second reinforcement 320 is arranged horizontally. It can be understood that the first reinforcement 310 and the second reinforcement 320 are perpendicular to each other. The second reinforcement 320 has a first lug 322 on the side near the first reinforcement 310, and the first reinforcement 310 has a second lug 313 on the side near the second reinforcement 320. The second lug 313 is connected to the second flange 312. The second flange 312 is located on the side of the cover plate 200 away from the volute 100, and the second lug 313 is also located on the side of the cover plate 200 away from the volute 100. At least part of the structure of the first lug 322 and the second lug 313 overlaps, so that the first lug 322 and the second lug 313 can be connected by welding, so that the first reinforcement 310 and the second reinforcement 320 form a whole, improving the connection stability of the first reinforcement 310 and the second reinforcement 320, and making it less likely for the first reinforcement 310 and the second reinforcement 320 to detach from the cover plate 200.

[0049] Similar to the above embodiments, refer to Figure 7 and Figure 8 As shown, in some other embodiments, the second reinforcement 320 is also provided with a first lug 322 on the side opposite to the first reinforcement 310, and a second lug 313 can also be arranged on the third reinforcement 310. The first lug 322 and the second lug 313 overlap and are welded to each other.

[0050] In some embodiments, refer to Figure 3 As shown, along the length direction of the second reinforcement 320, the overlap length of the first lug 322 and the second lug 313 is L, where L is greater than or equal to 8mm. This setting ensures that the overlap area of ​​the first lug 322 and the second lug 313 is large, which is beneficial to increase the welding area of ​​the first lug 322 and the second lug 313, making welding operations easier and ensuring a stable connection between the first lug 322 and the second lug 313.

[0051] Reference Figure 2 and Figure 7 As shown, in some embodiments, the second reinforcement 320 extends in the vertical direction, and the lowest position of the second reinforcement 320 is lower than the highest position of the air inlet 210. This can increase the surface area of ​​the second reinforcement 320 and more comprehensively cover the surface of the cover plate 200, thereby improving the protective effect. The side of the second reinforcement 320 near the air inlet 210 is provided with a first notch 323 to avoid the air inlet 210, which can avoid blocking the airflow through the air inlet 210. For example, when the air inlet 210 is circular, the first notch 323 is arc-shaped.

[0052] Reference Figure 7As shown, in some embodiments, the cover plate 200 has a first side surface 230 and a second side surface 240 arranged back to back in a horizontal direction. In order to enable the air inlet 210 to better match the position of the fan 500 in the air duct 110 to improve air flow circulation, the air inlet 210 is closer to the first side surface 230, and the distance between the first side surface 230 and the inner wall of the air inlet 210 is less than the distance between the second side surface 240 and the inner wall of the air inlet 210. Since the thickness of the position between the first side surface 230 and the inner wall of the air inlet 210 is small, a boss portion 250 is arranged on the first side surface 230. The boss portion 250 can be understood as a thickening structure and has a certain reinforcing effect, which can improve the structural strength of the position between the first side surface 230 and the inner wall of the air inlet 210.

[0053] Referring to Figure 7 As shown, the reinforcing structure 300 further includes a third reinforcing member 330. The first reinforcing member 310 is arranged on the first side surface 230, and the third reinforcing member 330 is arranged on the second side surface 240. The third reinforcing member 330 covers the second side surface 240, so as to play a protective role for the positions of the first side surface 230 and the second side surface 240. The structure of the third reinforcing member 330 is substantially the same as that of the first reinforcing member 310. The third reinforcing member 330 is also configured in a C shape or a U shape, as shown in Figure 8 As shown, the third reinforcing member 330 is provided with a fourth flange 331 and a fifth flange 332. The fourth flange 331 and the fifth flange 332 are arranged opposite to each other. The third reinforcing member 330 is clamped to the back of the cover plate 200 by the fourth flange 331 and the fifth flange 332.

[0054] It should be further noted that, as shown in Figure 9 As shown, the first reinforcing member 310 on the first side surface 230 is provided with a second notch 314. The second notch 314 is used to avoid the boss portion 250. The boss portion 250 and the first reinforcing member 310 can jointly play a protective role for the position of the first side surface 230 of the cover plate 200. In the up-down direction, the length of the boss portion 250 is less than the length of the first reinforcing member 310, and does not hinder the arrangement of the first reinforcing member 310.

[0055] Referring to Figure 1 and Figure 2As shown, in some embodiments, the air duct assembly 1000 further comprises a shell 400 for connecting with the fan 500, the shell 400 covers the side of the volute 100 away from the cover plate 200, the shell 400 can be understood as a box-shaped structure, the shell 400 comprises a front side plate 450, a rear side plate 460, a lower side plate 470 and a left side plate 480 connected with each other, which enclose a containing cavity, the volute 100 is located in the containing cavity, the axis of the volute 100 is arranged in the left-right direction, in the assembly process, the volute 100 can be assembled into the shell 400 from right to left, the lower side plate 470 supports the volute 100, the front side plate 450 and the rear side plate 460 block the volute 100 in the front-rear direction, and the left side plate 480 blocks the left side of the volute 100, which plays a limiting and protecting role for the volute 100, and the fan 500 is connected with the left side plate 480. The material of the shell 400 can be the same as that of the reinforcing structure 300, the shell 400 can be made of plastic, metal or other materials, the hardness of the shell 400 is greater than that of the foam, that is, the hardness of the shell 400 is greater than that of the volute 100, and the specific hardness index can refer to the description of the above embodiments. The hardness of the shell 400 is relatively large, which can protect the volute 100, so that the reinforcing structure 300 does not need to be arranged on the surface of the volute 100, but only needs to be arranged on the cover plate 200, which can reduce the manufacturing difficulty, save the manufacturing steps and improve the manufacturing efficiency. It should be noted that the side of the volute 100 away from the cover plate 200 is provided with an avoiding opening for avoiding the connecting structure of the shell 400 and the fan 500, when the fan 500 is connected with the shell 400, the volute 100 is limited between the fan 500 and the shell 400, so that the shell 400 and the volute 100 are fixed together, and the shell 400 plays a protecting role for the volute 100.

[0056] Referring to Figure 2 and Figure 4 As shown, the shell 400 is provided with a first clamping hook 410, which can be a flange structure, referring to Figure 2 and Figure 9 As shown, the first reinforcing part 310 is provided with a first clamping hole 315, and the first clamping hook 410 is clamped and fixed with the first clamping hole 315, so as to fix the position of the cover plate 200. In this embodiment, the first reinforcing part 310 also plays a connecting role, because the hardness of the first reinforcing part 310 is relatively large, the first reinforcing part 310 can be clamped and fixed with the shell 400, and will not damage the cover plate 200. If the cover plate 200 is clamped and fixed with the shell 400, the structure of the cover plate 200 is easy to be damaged.

[0057] Referring to Figure 2 and Figure 5 As shown, in some embodiments, the front side plate 450 of the shell 400 is provided with a first through hole 430, referring to Figure 3As shown, the first reinforcing member 310 is provided with a first threaded hole 316, which is threadedly connected with a screw, and the screw passes through a first through hole 430, thereby fixing the first reinforcing member 310 with the shell 400, and in addition, the first clamping hook 410 is clamped with the first clamping hole 315 to realize double fixing, which can further improve the connection stability.

[0058] Similar to the first reinforcing member 310, in some embodiments, referring to Figure 7 and Figure 8 As shown, the third reinforcing member 330 is provided with a second clamping hole 333, referring to Figure 2 and Figure 6 As shown, the rear side plate 460 of the shell 400 is provided with a second clamping hook 420, which is clamped and fixed with the second clamping hole 333. In this embodiment, the third reinforcing member 330 is not only used for protecting the cover plate 200 but also used for connecting with the shell 400. Since the third reinforcing member 330 has a large hardness, the third reinforcing member 330 can be clamped and fixed with the shell 400, and will not cause damage to the cover plate 200. If the cover plate 200 is clamped with the shell 400, it is easy to cause the structure of the cover plate 200 to be damaged. In some embodiments, referring to Figure 7 and Figure 8 As shown, the third reinforcing member 330 is further provided with a second threaded hole 334, which is threadedly connected with a screw, referring to Figure 2 and Figure 6 As shown, the rear side plate 460 of the shell 400 is provided with a second through hole 440, and the screw passes through the second through hole 440, thereby fixing the third reinforcing member 330 with the shell 400, and in addition, the second clamping hook 420 is clamped with the second clamping hole 333 to realize double fixing, which can further improve the connection stability.

[0059] The utility model embodiment further provides a kind of heat pump equipment, heat pump equipment includes box, first heat exchanger, compressor, second heat exchanger, fan 500 and the air duct assembly 1000 of above-mentioned embodiment, first heat exchanger, second heat exchanger, compressor, air duct assembly 1000 and fan 500 are located in box, first heat exchanger divides the inner chamber of box into air inlet chamber and air outlet chamber, air inlet chamber is communicated with air inlet pipe, air outlet chamber is communicated with air outlet pipe, second heat exchanger and compressor are installed in air inlet chamber, air duct assembly 1000 is installed in air outlet chamber, second heat exchanger is provided with the refrigerant pipeline for connecting compressor and first heat exchanger, second heat exchanger is further provided with the water flow pipeline for connecting water supply pipe.First heat exchanger can be evaporator, and second heat exchanger can be plate heat exchanger.

[0060] The heat pump device mainly utilizes a compressor to compress refrigerant to release energy, in the working process, the compressor compresses the refrigerant in a low temperature and low pressure state and in a gaseous state into a high temperature and high pressure state, the refrigerant in the high temperature and high pressure state flows to the second heat exchanger and releases heat, the heat is transferred to the water flow pipeline through the second heat exchanger, so as to heat the water in the water flow pipeline, and then the hot water is transported out through the water supply pipe, when the refrigerant in the high temperature and high pressure state passes through the expansion valve or the throttling valve, the high temperature and high pressure liquid state refrigerant becomes a low temperature and low pressure gas-liquid mixed state, and then the low temperature and low pressure gas-liquid mixed state refrigerant passes through the first heat exchanger, the first heat exchanger absorbs heat from the surrounding environment to make the refrigerant vaporize, the refrigerant changes from a low temperature and low pressure liquid state into a low temperature and low pressure gaseous state, and the low temperature and low pressure gaseous state refrigerant returns to the compressor.
