The utility model discloses a to blow the entrance design in foot wind channel for with the tangent arc structure of air door, make the wind current do not have sufficient space to form the air current that circles round when the entry in foot wind channel is blown to make the air current can smoothly flow in and blow the foot wind channel, effectively eliminate the wind channel rumble, reduce the noise of whole car, improve the travelling comfort of whole car.
Description
Technical Field
The utility model belongs to the technical field of vehicle air conditioner, a vehicle air conditioner blows foot wind channel structure is related to, in particular to vehicle air conditioner that can reduce rumbling blows foot wind channel structure.
Background
The automotive air conditioning unit consists of a generally plastic casing, comprising, in a chamber formed by the casing, the components: the internal and external circulation air duct component is arranged in the internal and external circulation air duct, a filter is arranged in the internal and external circulation air duct, the filter is connected with the blower, and the other side of the filter is an air suction opening; a speed regulating module is arranged in the air duct in the air outlet direction of the blower; an evaporator assembly, a warm air assembly, a face-blowing defrosting air door assembly, a foot-blowing air door assembly and a cold-warm air door assembly are arranged in the air outlet cavity, the face-blowing defrosting air door assembly and the foot-blowing air door assembly are controlled by a mode driving plate through an air door rocker arm and an air door connecting rod, and the cold-warm air door assembly is controlled by a cold-warm air door gear; the mode zipper is connected to the mode zipper gear, when the mode zipper rotates, the mode gear is driven to rotate, the mode gear drives the mode dial to move, and the rocker arm and the connecting rod which are connected with the air door move to a required position along with the rotation of the mode dial and the track guide groove of the mode dial.
When the mode dial is adjusted to the foot blowing mode, the foot blowing air door is opened, and air flow enters the foot blowing air duct. The entrance of the traditional foot blowing air duct of the automobile air conditioner is usually of a fan-shaped structure, the inside of the air duct is wider than the entrance, as shown in fig. 1, when the air flow passes through the entrance of the foot blowing air duct 3, the wind flow at the fan-shaped area 4 of the entrance of the foot blowing air duct 3 circles round to form a vortex, cannot flow out in the air duct, forms continuous rumbling, and brings auditory discomfort to the user.
Disclosure of Invention
The utility model aims at providing a reduce vehicle air conditioner that bombs sound and blow foot wind channel structure, the entrance design that will blow the foot wind channel is for following the tangent arc structure of air door, makes the wind flow not have sufficient space to form the air current that circles round when the entry in foot wind channel is blown to make the air current can smoothly flow in and blow the foot wind channel, effectively eliminate the wind channel bombs sound, reduces the noise of whole car, improves the travelling comfort of whole car, the effectual problem that prior art exists of having solved.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: a foot blowing air channel structure of an automobile air conditioner for reducing the acoustic boom comprises an air conditioner shell, a foot blowing air door and a foot blowing air channel, wherein the foot blowing air door is installed in an inner cavity of the air conditioner shell, the foot blowing air channel is connected with the inner cavity of the air conditioner shell, and the foot blowing air channel is controlled to be communicated or disconnected with the inner cavity of the air conditioner shell through the foot blowing air door; the bottom of the foot blowing air duct inlet extends upwards and is an arc-shaped bottom edge, and the arc-shaped bottom edge is tangent to the foot blowing air door in a closed state.
The utility model discloses a reduce vehicle air conditioner of rumble and blow foot wind channel structure owing to adopt above-mentioned structure, has following beneficial effect:
the utility model discloses the bottom design that will blow foot wind channel entrance is upwards extending and be circular-arc base, and the foot air door that blows under arc base and the closure state is tangent, make the entrance broad in foot wind channel of blowing, its inside is narrower, the wind current does not have enough space to form the air current that circles round when the entrance in foot wind channel of blowing, but along the direction outflow wind channel in foot wind channel of blowing, avoid the wind current to circle round at the entrance in foot wind channel of blowing, eliminate wind channel rumble, reduce the noise of whole car, improve the travelling comfort of whole car.
The following describes a foot-blowing duct structure of an automotive air conditioner for reducing acoustic boom according to the present invention with reference to the accompanying drawings and embodiments.
