Detailed Description
In order that the utility model may be readily understood, a more complete description of the utility model will be rendered by reference to the appended drawings. Several embodiments of the utility model are presented in the figures. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "mounted" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, a condensate leakage preventing structure of a hvac case according to a first embodiment of the present utility model is shown, the condensate leakage preventing structure of an hvac case includes a left housing 10 and a right housing 20 matched with the left housing 10, the left housing 10 is provided with a first flange, the right housing 20 is provided with a second flange matched with the first flange, and the left housing 10 and the right housing 20 are fixedly connected through the first flange and the second flange. In order to more specifically describe the fixing schemes of the left casing 10 and the right casing 20, the first flange is provided with a plurality of first through holes, the second flange is provided with a plurality of second through holes coaxial with the first through holes, and when the fixing schemes are actually installed, only a plurality of first bolts are required to sequentially penetrate through the first through holes and the second through holes, and then nuts are screwed on the first bolts. For more convenient installation and improved working efficiency, a plurality of third through holes are formed in the first flange, a plurality of threaded pins 30 are arranged at positions corresponding to the third through holes in the second flange, and second bolts penetrate through the third through holes and are screwed into the threaded pins 30 to fix the left shell 10 and the right shell 20. In this way, the threaded pin 30 may be directly formed by molding plastic and processed at one time during the production of the right housing 20, so that when the left housing 10 and the right housing 20 are actually mounted, the second bolt only needs to pass through the third through hole and screw into the threaded pin 30 to fix the left housing 10 and the right housing 20, thereby reducing the practicality of nuts and improving the assembly efficiency of workers.
Further, the structure for preventing condensate leakage of the heating ventilation air conditioning box further comprises a first rubber ring 60, and the material is EPDM. The second flange is provided with a second rubber groove 70 matched with the first rubber ring 60 along the self contour direction, and the first rubber ring 60 is placed in the second rubber groove 70. Because the installation mode of the first flange and the second flange is the rigid connection, the leakage risk is also realized, the connection mode is changed into elastic connection by adding the first rubber ring 60, interference fit is realized during connection, and when condensate water flows down, the first rubber ring 60 can effectively prevent the condensate water from flowing out from the connection part of the first flange and the second flange, but normally flows out from the drain hole 40.
In order to further prevent the condensed water from leaking, the first flange is provided with a first protruding rib 50 at a position corresponding to the second rubber groove 70, and a distance from the top of the first protruding rib 50 to the bottom of the second rubber groove 70 is smaller than a line diameter of the first rubber ring 60. In this assembly mode, since the first flange is provided with the first rib 50 at the position corresponding to the second rubber groove 70, firstly, the first rib 50 changes the flowing direction of the condensed water, and increases the flowing resistance of the condensed water, and meanwhile, the first rib 50 abuts against the first rubber ring 60, so that the sealing effect is further improved.
Due to the symmetry of the direction, the design scheme can be adopted in the opposite direction, and specifically, the condensate water leakage preventing structure of the heating ventilation air conditioning box further comprises a second rubber ring, the first flange is provided with a first rubber groove matched with the second rubber ring along the outline direction of the first flange, and the second rubber ring is placed in the first rubber groove. Further, the second flanging is provided with a second convex rib at a position corresponding to the first rubber groove, and the distance from the top of the second convex rib to the bottom of the first rubber groove is smaller than the wire diameter of the second rubber ring. The design scheme is the same as the design scheme, but opposite in direction, and one of the design schemes can be selected according to the installation requirement or the convenience of production during actual assembly.
In summary, in the structure for preventing leakage of condensed water in the heating ventilation air-conditioning box according to the above embodiment of the present utility model, by arranging the first rubber ring 60 or the second rubber ring, the rigid connection is replaced by the elastic connection, and according to the requirement on the sealing effect, the pressure can be changed by changing the wire diameter of the first rubber ring 60, so as to further play the role of changing the sealing effect. Meanwhile, the first ribs 50 or the second ribs change the flowing direction of the condensed water, so that the flowing resistance of the condensed water is increased, and meanwhile, the pressure of the first rubber ring 60 or the second rubber ring can be changed according to the line diameter of the first rubber ring 60 or the second rubber ring, so that the risk of condensed water leakage is greatly reduced, the driving experience of a driver is improved, and the driving safety is also improved.
