Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] Aiming at the problems existing in the prior art, the present invention provides an air duct structure, a mobile air conditioner with an air duct structure and applications thereof. The invention will be described in detail below with reference to the accompanying drawings.
[0038] Such as figure 1 As shown, where d1 is the distance between the upper end surface of the centrifugal fan blade and the (upper) end surface of the volute, and d2 is the distance between the lower end surface of the centrifugal fan blade and the (lower) end surface of the volute (the size of d1 and d2 should be greater than 5mm, the reason...

The invention belongs to the technical field of air conditioners, and discloses an air duct structure, a mobile air conditioner with the air duct structure and application thereof. On the premise thatthe distance between the end face of a sinking table groove and the end faces of centrifugal fan blades meets the requirement, the overall air duct height is not changed, and the centrifugal fan blade height is increased by H1-h1 compared with a traditional centrifugal fan blade height. The distance between the upper end faces of traditional centrifugal fan blades and an upper volute is d1, the distance between the lower end faces of the centrifugal fan blades and a lower volute is d2, and the height of the centrifugal fan blades is h1; the height of the centrifugal fan blades of the air ductstructure is H1, the distance between the upper end faces of the centrifugal fan blades and the upper volute is D1, and the distance between the lower end faces of the centrifugal fan blades and thelower volute is D2; D1 is greater than or equal to d1, and D2 is greater than or equal to d2; and H1 is greater than h1. According to the air duct structure, the mobile air conditioner with the air duct structure and the application thereof, on the premise that the height of the mobile air conditioner is not changed, the air duct structure is changed, the centrifugal fan blade height is increased,and the air outlet amount is increased; the overall performance of the mobile air conditioner is improved; and the change of the structure has no influence on the whole cabinet installation amount.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an air duct structure, a mobile air conditioner with the air duct structure and applications thereof. Background technique [0002] At present, the patent No. 201920720604.1 discloses an air duct structure and a mobile air conditioner. The technical solution can improve the utilization rate of the airflow in the air duct by the wind wheel. Patent No. 201920547041.0 discloses an air duct structure and an air conditioner. By setting multiple air guide sections with different curvatures, it is convenient to enhance the air outlet effect of the air duct and reduce aerodynamic noise. [0003] 201811243723.9, 201811245972 .1, 201821731392 .9, 201821732164 .3 The above patents achieve smooth air flow and reduce noise by setting the structural parameters of the volute tongue of the air duct. However, the above-mentioned patents do not provide technical improvements ...
