For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figure 1-5 The embodiment of the present application provides a disinfection and drying device for a clothes drying machine, including: a drying module 10 and an ultraviolet disinfection module 20. The drying module 10 is provided with a fan 12 and an air duct 11. The fan 12 is arranged inside the air duct 11 to generate airflow. The air outlet end of the air duct 11 is inclined relative to the vertical direction, so that the airflow is blown out at a certain angle. The ultraviolet disinfection module 20 is arranged on one side of the air outlet end of the air duct 11, and its light outlet surface is inclined so that the irradiation direction of the ultraviolet light emitted by the ultraviolet disinfection module 20 is inclined in the same direction as the airflow direction. Under this setting mode, the ultraviolet light and the airflow act on the clothes drying below at the same time, which effectively increases the blowing range and the disinfection range, and improves the disinfection and drying efficiency.

[0033] Further, in some embodiments, the drying module 10 includes an upper air guide plate 111 and a lower air guide plate 112 arranged in parallel, and the two are arranged to form an air duct 11. The upper air guide plate 111 and the lower air guide plate 112 are both arc panels, and the lower air guide plate 112 is arranged below the upper air guide plate 111. The fan 12 is arranged in parallel between the upper air guide plate 111 and the lower air guide plate 112 along the length direction. The air inlet ends of the upper air guide plate 111 and the lower air guide plate 112 are arranged horizontally, so that the airflow enters the air duct 11 horizontally; the air outlet ends of the upper air guide plate 111 and the lower air guide plate 112 are inclined at a certain angle relative to the horizontal plane, and blown toward the clothes hung and dried below, so that the direction of the outlet airflow is at a certain angle to the direction of the inlet airflow. With this arrangement, inclined air outlet is achieved while simplifying the structure of the overall disinfection and drying device 100, saving the swinging component used to adjust the air outlet angle in the traditional way, while also avoiding air flow loss caused by the use of the swinging component, thereby ensuring the air outlet of the disinfection and drying device.

[0034] Furthermore, in this embodiment, the air outlet ends of the upper air guide plate 111 and the lower air guide plate 112 extend downward and are inclined toward their air inlet ends, so that the outlet airflow direction and the inlet airflow direction form an angle less than 90°.

[0035] Preferably, the air outlet ends of the upper air guide plate 111 and the lower air guide plate 112 are arranged in parallel to form an air duct outlet 114, and the inclination angle relative to the horizontal plane is 30-60°, which can directly direct the airflow to the clothes more effectively, increase the blowing range, and reduce the loss of airflow.

[0036] Further, in some embodiments, the two ends of the air duct 11 are provided with fixing plates 113 parallel to the air flow direction, and the fixing plates 113 are fixedly connected to the upper air guide plate 111 and the lower air guide plate 112 to form the air duct 11, and the two ends of the fan 12 are connected to the fixing plates 113 and are arranged in parallel between the upper air guide plate 111 and the lower air guide plate 112. In this embodiment, the upper air guide plate 111 and the fixing plate 113 are integrally formed, and the lower air guide plate 112 is provided with a fixing portion 1121 at its end in the length direction, and the fixing portion 1121 is fixedly connected to the fixing plate 113 by a locking member or a detachable connection structure.

[0037] Preferably, the fan 12 is a cross-flow fan 12 .

[0038] Furthermore, in some embodiments, the drying module 10 is also provided with a heating component 13 for heating the airflow. The heating component is arranged parallel to the fan 12, and its end is fixedly connected to the fixing plate 113. In this embodiment, the heating component is arranged at the air inlet end of the air duct 11, and its two ends are respectively locked to the fixing plate 113 by locking members. The heating component generates heat to exchange heat with the airflow to form a hot airflow, which is then blown to the surface of the clothes through the air duct outlet 114 by the fan 12 to dry the clothes. When it is not necessary to heat the airflow, the heating component can be turned off separately, and the fan 12 only blows the airflow of normal temperature to the surface of the clothes to achieve the air drying function.

[0039] Specifically, the heating component is a PTC heater, which has the advantages of low thermal resistance and high heat exchange efficiency. At the same time, the PTC heater is an automatic constant temperature and power-saving electric heating component with high safety performance, which will not cause surface overheating, thereby avoiding safety hazards such as burns and fire. The PTC heater is provided with a number of heating plates parallel to the air flow direction at intervals along its length. When the PTC heater is working, the heating plates conduct heat and exchange heat with the air flow to form a hot air flow, and then the hot air flow flows to the air outlet through the air flow channel between two adjacent heating plates.

[0040] See also Figure 1 , Figure 4 and Figure 5 Furthermore, in some embodiments, the ultraviolet disinfection module 20 is provided with an ultraviolet lamp board 21, which is arranged parallel to the air duct outlet 114 along the length direction, located on the outside of the air outlet end of the upper air guide plate 111, or located on the outside of the air outlet end of the lower air guide plate 112.

[0041] Preferably, the ultraviolet lamp panel 21 is fixedly arranged below the lower air guide plate 112 and arranged parallel to the lower air guide plate 112 along the length direction. Under this arrangement, the overall size of the disinfection and drying device 100 is smaller, which is more conducive to the structural design inside the clothes drying machine. The side of the ultraviolet lamp panel 21 away from the air outlet end of the lower air guide plate 112 is arranged to be tilted upward, forming a certain angle with the horizontal plane, so that the ultraviolet lamp panel 21 can emit light at an angle.

[0042] Furthermore, the ultraviolet lamp panel 21 is provided with a plurality of light sources 211 arranged in an array for emitting light in the ultraviolet band. The light emitting surface of the light source 211 is inclined at a certain angle relative to the horizontal plane to achieve inclined light emission of the ultraviolet lamp panel 21. It is understandable that the inclination angle of the ultraviolet lamp panel 21 can be adjusted according to the actual relative position of the ultraviolet lamp panel 21 and the clothes below. Preferably, the light emitting surface of the light source 211 is perpendicular to the direction of the outlet air flow, so that the inclination angle of the ultraviolet light is consistent with the inclination angle of the outlet air flow.

[0043] Furthermore, the disinfection and drying device 100 is also provided with a panel 30, which is fixedly arranged below the air duct 11. The panel 30 is provided with a panel air outlet 31 and a lamp board mounting groove 32, and the panel air outlet 31 is arranged directly opposite to the air duct air outlet 114, and the air flow is blown out toward the clothes below through the panel air outlet 31. The lamp board mounting groove 32 is arranged on one side of the panel air outlet 31, and the ultraviolet lamp board 21 is fixedly arranged in the lamp board mounting groove 32, and the light source 211 emits ultraviolet light toward the clothes below. This arrangement makes the disinfection and drying device 100 highly integrated, more integrated, and more beautiful in appearance.

[0044] Furthermore, in some embodiments, the bottom of the lamp board mounting groove 32 is tilted relative to the horizontal plane, the ultraviolet lamp board 21 is tilted in the same direction as the bottom of the lamp board mounting groove 32, and is fixedly connected to the lamp board mounting groove 32, so that the ultraviolet lamp board 21 emits light in an inclined manner. Preferably, the ultraviolet lamp board 21 is arranged parallel to or abuts against the bottom plane of the lamp board mounting groove 32, so that the ultraviolet lamp board 21 is tilted. Specifically, the tilt angle of the bottom plane of the mounting groove can be set according to the actual irradiation angle requirements. In other embodiments, an inclined lamp board mounting seat is provided in the lamp board mounting groove 32, which can also be used to achieve the tilted setting of the ultraviolet lamp board 21, but is not limited thereto.

[0045] Furthermore, the ultraviolet lamp board 21 can be attached to the bottom of the lamp board mounting groove 32 by means of adhesive, or can be locked to the bottom of the groove by means of a locking member. In some embodiments, the ultraviolet lamp board 21 and the lamp board mounting groove 32 are fixedly connected by means of a locking member and adhesive, and at the same time, the ultraviolet lamp board 21 can be prevented from aging and deformation during long-term use, thereby causing the light output angle of the light source 211 to change and affect the sterilization efficiency.

[0046] Furthermore, in some embodiments, the panel 30 is formed of sheet metal in one piece, has a simple structure, and does not require complicated assembly procedures; the lamp board mounting groove 32 only needs to be stamped in one step, which is convenient for adjusting the shape of the lamp board mounting groove 32 according to actual needs. In addition, the UV lamp board 21 is directly fixed to the sheet metal, which is beneficial to the heat dissipation of the UV lamp board 21, improves the light output efficiency of the UV lamp board 21, reduces light decay, and increases the service life of the UV disinfection module.

[0047] Furthermore, in some embodiments, the ultraviolet disinfection module 20 is also provided with a lampshade 22, which is inserted into the lamp panel mounting groove 32, and its outer end surface is arranged horizontally with the lower end surface of the panel 30, further improving the integrity of the disinfection and drying device 100. The lampshade 22 is provided with a light outlet 221 at the position of the light source 211 for light emission, so as to avoid the lampshade 22 blocking the light emission of the light source 211 and reducing the light emission efficiency. Preferably, the light outlet 221 is arranged to be inclined in the same direction as the ultraviolet light, so as to avoid the lampshade 22 blocking the ultraviolet light emitted by the light source 211 when the light source 211 is inclined to emit light.

[0048] Furthermore, the ultraviolet disinfection module 20 is also provided with a buckle structure, which includes an elastic arm buckle provided on the lampshade 22 and a buckle position provided at the bottom of the lamp board mounting groove 32. The lampshade 22 is inserted into the lamp board mounting groove 32, and the elastic arm buckle is buckled in the buckle position to achieve relative fixation of the lampshade 22 in the lamp board mounting groove 32, thereby preventing the lampshade 22 from falling off from the lamp board mounting groove 32 during use. In other embodiments, the buckle structure may also include a convex point provided on the upper outer wall of the lampshade 22 and a groove provided on the side wall of the lamp board mounting groove 32, and the groove and the convex point are adapted to buckle, but the invention is not limited thereto.

[0049] Furthermore, in some embodiments, the lampshade 22 is also provided with a plurality of fixing columns, which are protrudingly arranged between adjacent light exit holes 221 , and whose ends abut against the ultraviolet lamp board 21 , which can further effectively prevent the ultraviolet lamp board 21 from aging and bending.

[0050] See also Figure 1 and Figure 6The embodiment of the present application also provides a clothes drying machine, including a main machine and a drying rod, wherein the drying rod is arranged below the main machine in parallel with the length direction of the main machine and is connected to the main machine through a pull rope. Further, the main machine includes at least one set of disinfection and drying devices, wherein the disinfection and drying devices 100 are arranged on one side or both sides of the main machine along the length direction of the main machine, and the air flow of the disinfection and drying devices 100 is blown downwardly to the drying rod on the same side and the drying area below the drying rod to dry or air-dry the clothes; the ultraviolet light emitted by the disinfection and drying devices 100 can be simultaneously or individually irradiated downwardly to the drying rod on the same side and the drying area below the drying rod.

[0051] Preferably, the host is provided with two side panels 200, two groups of disinfection and drying devices 100 and two drying rods. The disinfection and drying devices 100 are arranged parallel to the side panels 200 along the length direction of the side panels 200, and the side panels 200 are arranged on the air inlet side of the air duct 11. The two drying rods are respectively arranged below the two groups of disinfection and drying devices 100 for hanging clothes. The side panels 200 are provided with air inlets, and the fan 12 draws the external airflow into the air duct 11 through the air inlet. After heating treatment, the air is blown out through the panel air outlet 31 at an angle toward the clothes below to dry the clothes. At the same time, the ultraviolet disinfection module 20 emits ultraviolet light when it is working, and irradiates the clothes at an angle toward the clothes below through the light outlet 221 to disinfect and sterilize the clothes.

[0052] Compared with the prior art, the beneficial effects of the embodiments of the present application are: by adjusting the irradiation angle of the ultraviolet disinfection module, the ultraviolet light is distributed more evenly in the target area, thereby improving the irradiation effect; at the same time, the drying module cooperates with the same-direction inclined air outlet to reduce air flow losses and improve drying efficiency.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent.
