Description

Technical Field

[0001] The present invention relates to the technical field of intelligent toilets, and particularly to a drying device, a cover plate and a toilet. Background Art

[0002] Currently, intelligent toilets are generally equipped with drying devices. However, the air outlets of common drying devices are horizontal air outlets, and the air body directly discharges from the air outlet, and the position of the air outlet is relatively high, resulting in that most of the warm air only acts on the rear end of the buttocks, and the user's genitals cannot achieve the drying effect, and the utilization rate of the air body is relatively low. Eventually, the user needs to wipe with a tissue, and the user experience is relatively poor. To overcome this defect, a powerful drying fan is adopted in the prior art. Although the problem that the user's genitals cannot be dried is solved to a certain extent, its production cost has increased. Summary of the Invention

[0003] Aiming at the deficiencies existing in the background art, the purpose of the present invention is to provide a drying device, a cover plate and a toilet.

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] A drying device includes a fan. A heating wire is provided at the outlet of the fan. A wind guiding component is installed at the outlet of the fan. The wind guiding component includes a wind guiding elbow fixedly connected to one end of the fan outlet and a wind guiding straight pipe slidably sleeved on the other end of the wind guiding elbow. A wind guiding cover is provided at the end of the wind guiding straight pipe. A wind guiding concave portion is provided in the wind guiding cover. A first wind guiding inclined surface is provided on one side of the wind guiding concave portion. An air outlet is provided on one side of the end of the wind guiding straight pipe close to the first wind guiding inclined surface. A wind guiding piece is pivotally connected to the other end of the wind guiding elbow. During the sliding process of the wind guiding straight pipe, the wind guiding piece always abuts against the wind guiding concave portion and guides the air body to flow towards the first wind guiding inclined surface, so that the air body sprays out from the air outlet from bottom to obliquely upwards;

[0006] The wind guiding elbow includes a horizontal portion and a vertical portion connected to each other. The horizontal portion and the vertical portion are smoothly transitionally connected. The wind guiding straight pipe is slidably sleeved on the vertical portion;

[0007] The wind guiding piece includes a straight portion and an arc portion provided at one end of the straight portion. The other end of the straight portion is pivotally connected to the other end of the wind guiding elbow. The arc portion abuts against the wind guiding concave portion under its own weight.

[0008] Further, a smoothly transitional wind guiding surface is provided on the inner sides of the arc portion and the straight portion. The wind guiding surface is flush with the inner wall surface on one side of the wind guiding elbow. And a sealing portion is provided on the outer side of the straight portion. Under the action of the self-weight and wind pressure of the wind guiding piece, the sealing portion is hermetically fitted with the inner wall surface on one side of the wind guiding straight pipe.

[0009] Further, a second air guiding inclined surface is provided on the other side of the air guiding concave portion. During the sliding process of the air guiding straight pipe, the arc portion is always in contact with the second air guiding inclined surface under its own weight.

[0010] Further, a transition portion is provided between the first air guiding inclined surface and the second air guiding inclined surface to reduce the energy loss of the air body from the first air guiding inclined surface to the second air guiding inclined surface.

[0011] Further, the included angle between the first air guiding inclined surface and the horizontal plane is 30 - 50 degrees, and the included angle between the second air guiding inclined surface and the horizontal plane is 35 - 45 degrees.

[0012] Further, the ratio of the air passing cross-sectional area of the air guiding straight pipe to the air passing cross-sectional area of the air outlet is 2:1.

[0013] Further, a first limiting portion is provided at the other end of the air guiding elbow pipe, and the air guiding straight pipe is provided with a second limiting portion that can be in contact with the first limiting portion to prevent the air guiding straight pipe from disengaging from the air guiding elbow pipe during the sliding process.

[0014] Further, an input portion is provided on the outer side of the air guiding straight pipe. The input portion is drivingly connected to the output end of the motor, and the motor drives the air guiding straight pipe to slide through the input portion.

[0015] A cover plate includes a lower cover and also includes a drying device as described above. The drying device is installed on the lower cover.

[0016] A toilet includes a toilet body and also includes a cover plate as described above. The cover plate is installed on the toilet body.

[0017] The beneficial effects of the present invention are as follows:

[0023] 6. A drying device proposed by the present invention, the included angle between the first air guide inclined plane and the horizontal direction is 30 - 50 degrees, increasing the warm air action area and reducing the drying dead angle.

[0024] 7. A drying device proposed by the present invention, the ratio of the air passing cross-sectional area of the air guide straight pipe to the air passing cross-sectional area of the air outlet is 2:1, ensuring the wind force intensity of the air flow at the air outlet.
