Description

TECHNICAL FIELD

[0001] The utility model relates to the heating equipment field of passenger car, especially out of a kind of air structure and passenger car on -vehicle heating device. BACKGROUND

[0002] At present, heating of passenger car carriage is mostly by engine waste heat, independent water heating, electric heater (PTC) and air conditioning, and the heat transfer mode of such heating system is heat convection, using air as heat exchange medium to heat air in the vehicle to improve temperature in the carriage. The air outlet structure of the heating device of passenger car, as the terminal part of the heating system, is the passage for new air or circulating air after heat treatment by the heating device to enter the vehicle space, and in this case, the air volume and direction of the air outlet of the heating device will affect the heating efficiency in the vehicle.

[0003] The air outlet adjusting assembly of the air conditioner of the automobile disclosed in the Chinese utility model patent with the authorization announcement No. CN209365844U is installed side by side on the upper side of the display screen of the automobile central control, and by turning the front and rear two blade structures of the air outlet, the air direction of the air outlet can be adjusted up and down and left and right. However, since the air outlet is directly arranged in front of the driver or passenger, the blowing direction of the air outlet is concentrated in the front area of the automobile central control, and the vehicle interior environment on the left and right sides of the central control cannot be considered, which leads to a large temperature difference between the blowing part and other parts of the body of the driver or passenger, reducing the riding comfort. For passenger cars, due to the large interior space of the carriage, the air outlet adjusting assembly of the above-mentioned prior art has the defect of insufficient adjustment range.

[0004] For example, the air outlet assembly of the air conditioner of the automobile roof disclosed in the Chinese utility model patent with the authorization announcement No. CN222310324U includes an outer shell, an inner shell and louver blades. The inner wall of the outer shell is consistent with the shape of the outer shell, so that the inner shell and the outer shell are rotationally and sealingly connected. Adjusting the air direction can also avoid air leakage. The inner shell can be flipped along the X-axis to adjust the X-axis air direction. The louver blades are arranged in multiple numbers and are rotationally connected to the inner shell. The multiple louver blades are interconnected, that is, turning one louver blade along the Y-axis can flip the remaining louver blades together to adjust the Y-axis air direction. Compared with the above-mentioned prior art, the cooperation between the shell and the blade makes the air outlet angle adjustable along the X-axis or the Y-axis, which improves the method of adjusting the air outlet angle by setting multiple louver structures in the prior art, making the air direction adjustment more convenient and the structure simpler and easier to replace. Although it has better air direction adjustment capability, the opening area of a single air outlet is small, so the air conditioning air can only cover a limited area in the vehicle. When the interior space of the carriage is large, the above-mentioned prior art still has the defect of insufficient adjustment range. UTILITY MODEL CONTENTS
