Abstract

A vehicle heating and ventilation system comprising a bottom air duct (15) that combines the front air duct, the air ducts for heating the legs of the driver and front passenger, which interfaces with the floor tunnel on one side and with the central air duct (1) on the other, and is attached by the brackets (19) to the instrument panel, and the system also contains side air ducts (6, 7) of the body ventilation with nozzles (8, 9) at the end sections and interconnected by a central air duct (1) having la (2) ventilation body and guiding the window (3) for heating and ventilation of the windscreen. The technical result consists in simplifying the design and, as a result, reducing the parts included in the system, in reliable sealing of the system, as well as increasing the rigidity (frame) of the structure in the lower part and eliminating the rattle of the air ducts when operating the car.

Description

The utility model relates to the field of transport engineering, namely, to the heating and ventilation of the rear of the cabin and the creation of comfortable conditions in vehicles, such as cars.

The technical solution of the vehicle heating and ventilation system is known, RF patent No. 24151, publication date July 27, 2002, class. B60H 1/24, comprising a front air duct (18) connected to the heater (4), air ducts (16, 17) for heating the feet of the driver and front passenger, also connected to the heater, and side air ducts (9, 10) of the body ventilation with nozzles ( 12, 13) at the end sections and interconnected by means of a central air duct (14) with a nozzle (15) for ventilation of the body through an intermediate housing (11). The central air duct (14) is connected to the windshield heating duct (1), mounted on the instrument panel and docked with the heater.

The disadvantage of the technical solution is the complexity of the design, insufficient rigidity in the lower part of the structure, as well as the presence of three air ducts in the lower part, which requires the use of complex technological equipment for assembling the unit.

The objective of this utility model is aimed at creating such a system, which is aimed at simplifying the design and, as a result, reducing the parts included in the system, at reliable sealing of the system, as well as

to increase the rigidity (frame) of the structure and instrument panel in the lower part and the exclusion of rattling of air ducts during car operation.

To solve this problem, the following vehicle heating and ventilation system is proposed, comprising a lower air duct that combines the front air duct, the air ducts for heating the legs of the driver and front passenger, which is connected to the floor tunnel on one side and with the central air duct on the other, and is attached by the brackets to the dashboard, and the system also contains side air ducts for body ventilation with nozzles at the end sections and interconnected by means of ntralnogo air duct with a nozzle body ventilation.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition of “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, feasibly, reproducibly, therefore, meets the patentability condition "industrial applicability".

The essence of the technical solution is illustrated in the drawings:

The vehicle’s heating and ventilation system is a system of air ducts and guide nozzles designed to distribute and distribute air from an air conditioner through the vehicle interior in the heating, ventilation and air conditioning mode of the body and create comfortable conditions in the vehicle interior.

The heating and ventilation system includes a central air line (1), on which nozzles (2) for body ventilation and a guide window (3) are located for heating and ventilation of the windshield. On the sides of the central air duct (1) there are openings (4) of a circular shape with a bushing in diameter, with protrusions (5) located on it, onto which the side air ducts (6, 7) of the body ventilation rigidly fit, having nozzles (8, 9 ) at the end sections, which are fastened with the help of female cuffs (10) made in the rear part of the nozzles (8, 9). Cuffs (10) cover the end sections of the lateral air ducts (6.7), on which spherical protrusions (11) are made, to prevent rattling of nozzles during operation and to facilitate the installation of air ducts (6, 7) in nozzles (8, 9).

To give structural rigidity and to prevent vibration and sagging, the side air ducts (6, 7) have brackets (12) spaced along their length and through which the air ducts (6, 7) are rigidly attached to the instrument panel frame (13).

In the lower part, the central air duct (1) has triangular projections (14), on which the lower air duct (15) is latched, having an outlet channel (16) on the left for heating the driver’s legs, an outlet channel (17) on the right for heating the passenger’s legs, and in the center the exhaust channel (18), which fits into the floor tunnel (not shown) and heats the rear of the cabin. For rigidity of the lower air duct

(15) has two horizontal brackets (19) having an inverted U-shaped cross section made with the open side up and having a bottom with an opening for mounting brackets (19) to the instrument panel with a screw connection (20).

The claimed design of the air distribution system of ventilation and heating provides uniform distribution, wiring and regulation of air flows in the passenger compartment while simplifying the design.
