It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without the use of these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.
[0031] On the one hand, an embodiment of the present application provides a drying device, such as Figures 1 to 7As shown in the figure, the drying device includes a drying air duct 1, a fan assembly 2, and a spraying assembly 3. An installation groove 11 is provided on the side wall of the drying air duct 1. The air inlet 13 and the air outlet 14 of the drying air duct 1 are respectively communicated with the inner tub of the washing machine. The fan assembly 2 includes an impeller 21 and a driving member 22. The driving member 22 is installed in the drying air duct 1. The driving member 22 is drivingly connected to the impeller 21. The impeller 21 is arranged in the drying air duct 1. The spraying assembly 3 includes a spray head 31. The spray head 31 is embedded and installed in the installation groove 11 and is arranged towards the impeller 21 to wash the lint on the impeller 21.
[0032] Most current washing machines have a drying function. During the process of drying clothes, the intake air of the impeller 21 will suck the lint from the inner tub into the drying air duct 1. Most of the lint will accumulate and remain on the blades of the impeller 21, and the other lint will remain inside the drying air duct 1. When too much lint has accumulated, the rotation of the impeller 21 will be affected. At this time, only by disassembling the entire drying air duct 1 can the drying air duct 1 and the impeller 21 be cleaned thoroughly, so that the drying function can return to normal, which affects the drying efficiency. However, the disassembly is too complex and the cleaning efficiency is low.
[0033] The drying device provided by the embodiment of the present application is provided with a spray head 31 in a concealed manner in the drying air duct 1. The spray head 31 is arranged towards the impeller 21. The spray head 31 can be used to spray and wash the impeller 21, wash away the lint remaining on the impeller 21 during drying, and discharge these lint together with the water after washing the impeller 21. It can reduce the lint accumulation on the impeller 21 and the drying air duct 1, ensure that the impeller 21 can work normally, improve the drying efficiency of the drying device, and the spray head 31 adopts a concealed installation structure in the drying air duct 1, which can avoid interfering with the structure of the drying air duct 1 and the air flow therein, and ensure better drying performance.
[0034] The installation position of the impeller 21 in the drying air duct 1 can be determined according to actual needs. For example, it can be arranged at the air inlet 13, in the main air duct of the drying air duct 1, or at the air outlet 14, etc.
[0035] Here, a separate cleaning program can be set to enable the spray head 31 to clean the impeller 21 independently. Or, when the washing machine is washing clothes, the water in the washing machine can be used to synchronously clean the impeller 21.
[0036] In some embodiments, the spraying assembly 3 includes a water inlet pipe 32. A through hole 12 is provided on the side wall of the installation groove 11. The water inlet pipe 32 passes through the through hole 12 and is communicated with the spray head 31. The water inlet end of the spray head 31 is connected to the water inlet pipe 32, and the water inlet pipe 32 is hermetically connected to the through hole 12.
[0037] Specifically, the water inlet pipe 32 penetrates into the drying air duct 1 through the through hole 12 at the installation groove 11. The water outlet end of the water inlet pipe 32 is communicated with the spray head 31. The water inlet pipe 32 introduces water into the spray head 31, and the spray head 31 sprays the water onto the impeller 21 and the inner wall of the drying air duct 1 for cleaning. The water inlet pipe 32 is hermetically connected to the through hole 12 to prevent the air and water in the drying air duct 1 from flowing out through the through hole 12. The side wall of the drying air duct 1 protrudes outward, and the space formed inside is the installation groove 11. Such a setting can ensure that the spray head 31 is directly connected to the water inlet pipe 32, and their positions are also close, ensuring that water can quickly enter the drying air duct 1. In some other embodiments, the water inlet pipe 32 extends into the drying air duct 1 and extends along the inner wall of the drying air duct 1 to the installation groove 11, and the water inlet pipe 32 is communicated with the spray head 31.
[0038] In some embodiments, the spray head 31 is provided with a plurality of spray holes 31a. The spray head 31 is arranged facing the outer peripheral surface of the impeller 21, and the plurality of spray holes 31a are sequentially and spaced apart along the axial direction of the impeller 21.
[0039] Specifically, the spray head 31 is provided with a plurality of circular spray holes 31a. The spray head 31 is located on the side wall of the drying air duct 1. The spray head 31 faces the outer peripheral surface of the impeller 21. The plurality of spray holes 31a are distributed along the axial direction of the impeller 21, that is, the spray holes 31a can wash the blades of the impeller 21, and the plurality of spray holes 31a can jointly wash each position on the blades. Such a setting can increase the washing coverage area of the spray head 31, thereby improving the washing effect on the impeller 21, minimizing the residual lint on the impeller 21, ensuring that the rotation of the impeller 21 is not affected, and improving the drying efficiency. In this embodiment, the hole edge of the spray hole 31a is provided with an inclined chamfer, which can make the water spray out from the spray hole 31a. In some other embodiments, the spray hole 31a is a square hole, and the square hole extends along the axial direction of the impeller 21.
[0040] In some embodiments, the diameter of the water inlet end of the spray head 31 is larger than the diameter of the spray hole 31a.
[0041] Specifically, the diameter of the spray hole 31a is smaller than the diameter of the water inlet end. The water inlet end is a round hole, and the spray hole 31a is a round hole. The water in the spray head 31 flows in from the large diameter and flows out through the small diameter, which can pressurize the water flow, making the water pressure sprayed out from the spray hole 31a greater, that is, the washing force of the spray head 31 on the impeller 21 is greater, thereby ensuring that the lint on the impeller 21 can be washed off as much as possible and improving the washing effect of the spray head 31 on the impeller 21.
[0042] In some embodiments, the spraying assembly 3 includes a sealing rubber ring 33. An annular slot 33a is provided on the outer peripheral wall of the sealing rubber ring 33. The water inlet pipe 32 passes through the sealing rubber ring 33. The sealing rubber ring 33 is clamped in the through hole 12 through the annular slot 33a. The spraying head 31 presses the sealing rubber ring 33 against the bottom wall of the installation groove 11. A sealing ring protrusion 32a is provided at the end of the water inlet pipe 32, and the sealing ring protrusion 32a is provided on the peripheral wall of the water inlet pipe 32.
[0043] Specifically, the sealing rubber ring 33 is frustum-shaped. An annular slot 33a is provided on the outer peripheral wall of the sealing rubber ring 33. The sealing rubber ring 33 is clamped in the through hole 12 through the annular slot 33a. The sealing rubber ring 33 is in interference fit with the through hole 12. One end of the spraying head 31 abuts against the sealing rubber ring 33 to press the sealing rubber ring 33 against the bottom wall of the installation groove 11. The bottom wall of the installation groove 11 abuts against one of the groove side walls of the annular slot 33a. The water inlet pipe 32 is in interference fit with the sealing rubber ring 33 to realize the installation and fixation of the water inlet pipe 32 and the spraying head 31. With this setting, when the washing machine is running, the spraying head 31 is not likely to move, improving the installation stability of the spraying head 31. The sealing rubber ring 33 can deform and completely seal between the water inlet pipe 32 and the through hole through its own deformation. A sealing ring protrusion 32a for sealing connection with the water inlet main pipe 5 is also provided at the end of the water inlet pipe 32, and the diameter of the sealing ring protrusion 32a is larger than the diameter of the water inlet main pipe 5.
[0044] In some embodiments, the side of the spraying head 31 facing the impeller 21 is flush with the inner wall of the drying air duct 1.
[0045] Specifically, the inner wall of the drying air duct 1 is arc-shaped. The surface of the spraying head 31 facing the impeller 21 is a curved surface, and this curved surface is flush with the inner wall of the drying air duct 1. With this setting, the spraying head 31 does not protrude outwards, so as to ensure that there will be no interference between the impeller 21 and the spraying head 31 when the impeller 21 rotates. And such a design can meet the technical requirements of the Archimedes air duct principle, so that the air flow in the drying air duct 1 will not be affected.
[0046] In some embodiments, the installation groove 11 is a trapezoidal groove. Chamfered edges are provided on the periphery of the spraying head 31, and the inclined sides of the spraying head 31 abut against the groove side walls of the trapezoidal groove.
[0047] Specifically, the installation groove 11 is a trapezoidal groove with a larger upper part and a smaller lower part, that is, the opening of the installation groove 11 is gradually decreasing in the direction from inside to outside. The outer shape of the spray head 31 is adapted to the installation groove 11, and an inclined chamfer is provided on the outer edge of the spray head 31. The hypotenuse of the inclined chamfer will abut against the groove side wall of the trapezoidal groove. With this setting, the installation groove 11 can play a guiding role, and the spray head 31 can be introduced into the installation groove 11 along the hypotenuse of the trapezoidal groove, which can make the installation of the spray head 31 easier. In some other embodiments, guiding ribs are provided on the groove side wall of the installation groove 11, and guiding grooves are provided on the outer peripheral wall of the spray head 31 corresponding to the guiding ribs. When the spray head 31 is installed, the guiding ribs cooperate with the guiding grooves so that the spray head 31 can move along the length direction of the guiding ribs.
[0048] In some embodiments, a limiting structure is provided between the installation groove 11 and the spray head 31, and the limiting structure is used to limit the movement of the spray head 31 in the installation groove 11.
[0049] Specifically, a limiting hole is provided at one end of the spray head 31, and the limiting hole is a tapered hole. A plug post is correspondingly provided on the bottom wall of the installation groove 11, and the plug post is inserted into the limiting hole. The plug post and the limiting hole are in an interference fit. When the spray head 31 completely falls into the installation groove 11, the plug post and the limiting hole are completely connected, playing a certain limiting role and being able to increase the installation stability of the spray head 31. In some other embodiments, a clamping interface is provided on the groove side wall of the installation groove 11, and a clamping member is correspondingly provided on the spray head 31. The clamping member can be clamped into the clamping interface. When the spray head 31 is installed in the installation groove 11, the clamping member is clamped into the clamping interface to limit the movement of the spray head 31 in the installation groove 11.
[0050] In some embodiments, the drying device includes a heating component 4, and the heating component 4 is installed in the drying air duct 1 and is used to heat the air flowing in from the air inlet 13 of the drying air duct 1. The heating component 4 is arranged at an interval from the inner wall of the drying air duct 1 and is arranged close to the air outlet 14 of the drying air duct 1.
[0051] Specifically, the heating component 4 includes a heating elbow pipe, and there is one heating elbow pipe. The heating elbow pipe is arranged at an interval from the inner wall of the air duct, and there is a flow gap on the heating elbow pipe. When air flows through the flow gap, the heating elbow pipe can transfer heat to the air, so that the air flow output from the drying air duct 1 is hot air, and the hot air is used to dry clothes, which can improve the drying effect. In some other embodiments, the heating component 4 includes heating wires, and a plurality of heating wires are arranged in the drying air duct 1 at intervals.
[0052] On the other hand, the embodiment of the present application provides a washing machine, including the drying device as described above.
