DETAILED DESCRIPTION

[0028] The utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] The utility model discloses a multifunctional air-drying machine. Figure 1-6 As shown, a preferred embodiment of the utility model may include a housing 1, a fan module 2, a sterilization and purification device 3, an ultrasonic horn 4, and a power supply device 5.

[0030] The housing 1 has a main body 13, a front cover 14, a rear cover 15 and a hollow inner cavity, the front end of the inner cavity is an air outlet 11, and the rear end is an air inlet 12. The shape of the housing 1 can be determined according to the installation space. The all-in-one machine of this embodiment is used for hidden installation under furniture such as cabinets, wardrobes, sofas, etc., and can be a flat rectangular structure. The front cover 14 of the housing 1 can be provided with an indicator light 8 for prompting air drying and power supply, and the indicator light 8 is electrically connected to the power supply device 5; the air outlet 11 is provided on the front cover 14; the air inlet 12 is provided on the rear cover 15, and a grille is provided at the air inlet 12 to protect the internal parts and the safety of the user.

[0031] The fan module 2 is installed in the housing 1, and may include an impeller group 21, a motor 22 and a housing 23. The impeller group 21 may include a plurality of cylindrical impellers connected in the axial direction, and each impeller may include a plurality of blades 211 arranged in the circumferential direction and a fixing member 212 for fixing the ends of the blades, and the blades 211 may be arc-shaped. The two ends of the impeller group 21 are rotatably connected to the housing 23 through a rotating shaft, and one end of the rotating shaft is also fastened to the output shaft of the motor 22, and the housing 23 may be fixed in the housing 1 by screws. The housing 23 is provided with an air inlet 231 and an air outlet 232 on both sides facing the air inlet 12 and the air outlet 11, respectively, and the air inlet 231 may be slightly larger than the air outlet 232. The fan module 2 of this embodiment belongs to cross-flow air supply. When the motor 22 is started, the impeller group 21 starts to rotate, and the air is sucked into the housing 23 from the air inlet 231, enters the impeller radially, and then is sent out of the housing 23 from the air outlet 232. This multi-impeller cross-flow air supply mode produces very concentrated wind, which can meet the requirements of all-in-one machines for small size but high air output power.

[0032] A trumpet-shaped air duct 6 may be provided between the fan module 2 and the air outlet 11. Since the blades 211 of the fan module 2 are arc-shaped, the housing 23 may also be in various shapes. For example, the upper and lower pieces of the housing 23 forming the air inlet 231 and the air outlet 232 in this embodiment are generally arc-shaped (e.g. Figure 6 As shown in the figure, the air outlet 232 is oriented downward, so the wind sent out from the impeller assembly 21 will also be blown downward to the ground, and cannot be blown over a large area of ​​the ground. The function of the air duct 6 is to guide the wind blown out by the fan module 2 to be parallel to the ground, which is conducive to drying the ground with maximum efficiency.

[0033] A protective net 7 may be provided in the air duct 6 near the fan module 2 to ensure safety and prevent injuries caused by accidentally entering the fan module 1. The air duct 6 is divided from the inside to the outside into a first cavity 61 and a second cavity 62 with the protective net 7 as the boundary. The first cavity 61 may be a flat rectangular channel that is exactly connected to the air outlet 232. The second cavity 62 may be a trumpet-shaped channel with a gradually increasing opening from the inside to the outside.

[0034] The sterilization and purification device 3 may include a plasma generator 31 and a plasma emitter head 32, and the plasma generator 31 is installed in the housing 1 and connected to the power supply device 5 and the plasma emitter head 32. The plasma emitter head may be provided with one or more, preferably two, and the two plasma emitter heads 32 may be provided on the left and right sides of the first cavity 61, so as to sterilize and purify the air more evenly. When the wind sent out by the fan module 2 passes through the plasma emitter head 32, the positive ions and negative ions generated by the plasma emitter head 32 are driven to flow, and the positive ions and negative ions combined in the flow process will discharge to sterilize and disinfect the inside of the air duct 6, and the positive ions and negative ions that follow the gas into the ambient air can achieve sterilization and disinfection of the air in the external environment. When the concentration of the emitted negative ions is greater than the concentration of the positive ions, the concentration of negative ions in the air can be ensured to be high, so that the negative ions can exist in the air for a long time, so as to purify and improve the quality of the air and remove odors. Of course, in theory, the sterilization and purification device 3 can be installed at any position where the air passes through the housing 1, and negative ions, ozone and other technologies can also be used instead of plasma.

[0035] The ultrasonic horn 4 can be installed on the inner side of the back cover 15 and emit ultrasonic waves outward, and the ultrasonic horn 4 is electrically connected to the power supply device 5. A plurality of holes are provided at the back cover 15 corresponding to the ultrasonic horn 4. The gaps under furniture such as cabinets, wardrobes and sofas are damp and hidden, and cockroaches and other insects are easily gathered. The ultrasonic horn is arranged at the rear of the all-in-one machine, and the ultrasonic waves it generates can act on the gathering places of cockroaches and other insects at the closest distance, reduce ultrasonic wave loss, and improve the insect repellent effect. The ultrasonic interference of the ultrasonic horn 4 and the fan module 2 dry the ground to improve the humid environment, effectively reducing the gathering of mosquitoes and cockroaches.

[0036] The power supply device 5 may include a control switch 51 and a circuit board 52. The control switch 51 is arranged outside the rear cover 15, and the circuit board 52 is arranged inside the housing 1. The control switch 51 is electrically connected to the circuit board 52, and the circuit board 52 is electrically connected to the fan module 2, the sterilization and purification device 3, the ultrasonic speaker 4 and the indicator light 8. The utility model adopts a safe voltage, which is safer to use than 220V high-voltage electrical appliances, especially when used in a humid environment such as a kitchen, and is also more energy-efficient.

[0037] The utility model is an all-in-one appliance with multiple functions such as surface air drying, air purification and sterilization, and mosquito and cockroach repelling. It is small in size and suitable for hidden installation in a narrow space without destroying the overall aesthetics of the space. The utility model can be installed in the gap under the cabinet, with the air outlet 11 facing outward. The air drying function of the fan module 2, the air purification and sterilization function of the sterilization and purification device 3, and the ultrasonic insect repellent function of the ultrasonic speaker 4 can be turned on and off respectively by controlling the switch 51. The utility model is particularly suitable for installation under the kitchen cabinet to improve its humid, bacteria-rich and insect-rich environment, but it is not limited to this scene. It can also be used in similar hidden places, such as under the sofa, wardrobe, etc.
