Problems solved by technology

[0002] In the current vehicle air conditioner, due to the limitation of the traditional fresh air inlet structure, the opening degree of this type of air inlet is not adjustable, not only the fresh air volume is small, but also the fresh air volume flowing into the compartment cannot be adjusted according to the actual situation in the compartment , and when the vehicle encounters heavy rain, the rainwater will even enter the air conditioner with the new air outlet, causing great inconvenience, and at the same time reducing the working efficiency of the air conditioner and greatly reducing the operating cost of the air conditioner

Embodiment 1

[0043] Such as figure 2 As shown, when the vehicle is running and the rainfall is large, the accumulated water in the water accumulation unit 7 will not cause rolling and splashing due to the blocking of the upper exchange unit 5, and avoid entering the air inlet 2 outside the vehicle.

Embodiment 2

[0045] Such as image 3 As shown, when the vehicle turns or tilts left and right, the rainwater overflows the water accumulation unit 7, but the exchange unit 5 prevents the water from flowing on both sides, which can also prevent rainwater from entering the air inlet 2 outside the vehicle.

[0046]In addition, this invention also has a new fresh air function: in the cooling state of the air conditioner, the angle of the damper unit 10 is adjusted by controlling the damper actuator module to realize fresh air (outer circulation) and partial fresh air (inner + outer circulation) of the air conditioner Or there is no stepless adjustment state such as fresh air (internal circulation).

[0047] The fresh air function control steps are as follows:

[0048] a. Press the key on the control panel (select on / off for fresh air) to turn on or off the fresh air;

[0049] b. Fresh air parameter setting, press and hold the selection key for 5 seconds, when the display shows the opening o...

Embodiment 3

[0051] Such as Figure 4 As shown, in the cooling state of the air conditioner, when the angle of the damper unit 10 is adjusted to 0° by controlling the damper actuator unit 6, the state of no fresh air can be realized.

Abstract

The invention provides an overhead vehicle air conditioning unit. The overhead vehicle air conditioning unit comprises an outside air inlet module, an inside air inlet module, an air processing module and a waterproof module, wherein the inside air inlet module is upwards arranged and communicated with an outside air inlet so as to form air movement between the outside air inlet module and the inside air inlet module; the air processing unit consists of an air door unit and an air door execution unit, is used for adjusting air between the outside air inlet module and the inside air inlet module, and the air door unit is arranged on the air door execution module; and the waterproof module consists of a flow guiding unit, a water accumulation unit, and an exchange unit, and the flow guidingunit is arranged at a position corresponding to the outside air inlet module and used for guiding liquid entering from the outside air inlet module to a special position; the water accumulation unit is used for containing the liquid entering from the flow guiding unit; and the exchange unit is movably arranged at the bottom of the water accumulation unit.

Description

technical field [0001] The invention relates to a top-mounted vehicle air-conditioning unit, in particular to a top-mounted vehicle air-conditioning unit capable of simultaneously realizing waterproof and fresh air 0-100% stepless adjustment functions. Background technique [0002] In the current vehicle air conditioner, due to the limitation of the traditional fresh air inlet structure, the opening degree of this type of air inlet is not adjustable, not only the fresh air volume is small, but also the fresh air volume flowing into the compartment cannot be adjusted according to the actual situation in the compartment. , and when the vehicle encounters heavy rain, the rainwater will even enter the air conditioner with the new air outlet, causing great inconvenience, and at the same time reducing the working efficiency of the air conditioner and greatly reducing the operating cost of the air conditioner. Contents of the invention [0003] In order to solve the problems in t...
