[0058] The warmer provided by the application is characterized in that: when working, the air outside the box body 5 enters the center of the fan 6 through the warmer air inlet on the panel 101 and the air collecting plate 10, the air is accelerated by the fan 6 and guided to the guide vane 8 by the air guide plate 9, the spiral air flow channel can avoid large flow rate loss in the air guiding process, the guide vane 8 converts the horizontal air flow into vertical air flow, avoiding vortex formation at the other end of the box body 5, and achieving the effect of rectification and vortex breaking. At the same time, the PTC heating element 7 heats the air flow in the spiral air flow channel, and the guide vane 8 is divided into multiple flow channels, so that the air flow is uniformly distributed and introduced into the air inlet of the air guide cover 1, the gradually tapered structure of the air guide cover 1 accelerates the air flow first and then sends it out along the first air guide channel and the second air guide channel, forming a converging high-speed air flow column in the center part, and also blowing air flow at a certain angle in the periphery, covering a larger range.

[0060] State 1: Before the first air guide channel is opened, the outer peripheral edge of the baffle section of the movable part 33 forms a closed state with the inner wall of the first air guide channel, the first air guide channel is closed, and the horizontal distance between the human body position and the center position of the air guide device is R, if R≥R1, the motor rotates, drives the nut or the sleeve to ascend along the screw or the lead screw by a distance h1, drives the hinge and the hinge section of the movable part to rotate around the hinge seat, and the baffle section rotates by a certain angle and separates from the inner wall of the first air guide channel, at this time, the first channel is opened, and the included angle between the baffle section and the vertical direction is α1; if R1>R>R2, the control part 31 descends by a distance h2, and the included angle between the baffle section and the vertical direction is α2; if R2≥R≥0, the control part 31 continues to descend by a distance h3, and the included angle between the baffle section and the vertical direction is α3, at this time, the baffle section coincides with the outer side surface of the first air guide part, and the first air guide channel is fully opened (wherein R1, R2, h1, h2, h3 are constants, and α1>α2>α3). During the above working process, the air guide cover is in a low-speed rotating state, and the baffle plate forms a fan-shaped air guide channel between the first air guide part and the second air guide part, effectively alleviating the phenomenon of uneven air supply at the outlet caused by the limitation of the air duct structure. The closer the human body is to the center position of the air supply structure, the larger the effective flow area of the air supply channel is, and the design purpose is to make the effective flow area of the air outlet larger and the outlet flow rate slower, thereby alleviating the problem of obvious blowing feeling caused by the too large outlet flow rate, and improving the bathing comfort.

[0061] State 2: for local drying mode, the driving part 21 controls the baffle section to close the first air guide channel, the high-temperature gas in the air duct is only transported by the second air guide channel, the air outlet of the second air guide channel is a converging air supply channel, which effectively improves the air supply speed and uses the flow gas wall effect to concentrate the high-temperature gas and quickly reach the surface of the object to be dried below, thereby effectively improving the drying efficiency.
