Multifunctional door and window profile with ventilation, noise elimination and heat resistance functions

Abstract

The invention discloses a multifunctional door and window profile with ventilation, noise elimination and heat resistance functions, which comprises a profile body, wherein the profile body is provided with a wind inlet communicated with outdoor air and a wind outlet communicated with indoor air; a ventilating channel communicated with the outdoor air and the indoor air is formed in cavities of the wind inlet, the wind outlet and the profile body; the ventilating channel is internally provided with an air door and a sound absorption module; and the profile body is internally provided with a heat insulating bridge formed by a heat insulating module. The profile body is provided with the wind inlet and the wind outlet which are communicated with the outdoor air and the indoor air so that the door and window profile has the function of ventilation; meanwhile, the profile body is internally provided with a rotatable air door; the air inlet quantity is controlled by adjusting the open degree of the air door; the profile body is also internally provided with the sound absorption module and the heat insulating module; and the ventilating quantity and requirements of people for indoor noise reduction and heat insulation are also met. The multifunctional door and window profile has the advantages of simple structure, low cost and attractive appearance.

Description

technical field [0001] The invention relates to a door and window profile, in particular to a door and window frame profile which can adjust the air intake volume, has the function of blocking heat input and effectively reducing noise. Background technique [0002] Existing door and window profiles can only serve as window frames and cannot complete the exchange of indoor air. In order to solve the above problems, some methods to solve the problem have emerged, such as the published Chinese utility model patent "A Ventilable Door and Window Profile" (Patent No. ZL200620014033.2), in which the air intake The outlet is directly arranged on the upper part of the profile. When it rains, the rainwater will flow into the profile and flow into the room through the indoor vent. Only four 90-degree bends can be realized. Therefore, there is a high flow path resistance. In the state of natural ventilation, it is almost impossible to achieve air entry; at the same time, after the vent...

[0002] Existing door and window profiles can only serve as window frames and cannot complete the exchange of indoor air

In order to solve the above problems, some methods to solve the problem have emerged, such as the published Chinese utility model patent "A Ventilable Door and Window Profile" (Patent No. ZL200620014033.2), in which the air intake The outlet is directly arranged on the upper part of the profile. When it rains, the rainwater will flow into the profile and flow into the room through the indoor vent. Only four 90-degree bends can be realized. Therefore, there is a high flow path resistance. In the state of natural ventilation, it is almost impossible to achieve air entry; at the same time, after the vent is set, no consideration is given to heat insulation and noise reduction. Relevant requirements, in today's environment that advocates "energy saving and emission reduction", it is definitely impossible to implement

[0003] Today, the more common way to solve the ventilation problem of soundproof windows is to insert a ventilator between the window frame and the glass. The Belgian patent of "Ventilatie-Inrichting" (Application No.: 1010057A6) discloses a ventilator, which is provided with air inlets and outlets on the ventilator, and a rotatable switch is arranged in the ventilator, and the ventilator is controlled by the switch In this way, although the problem of indoor ventilation is better solved by setting this type of ventilator between the glass and the window frame, at the same time, many other new problems are brought about after the ventilator is added. , such as the sealing and waterproofing of doors and windows is difficult to solve, because after the ventilator is installed, there will be a process gap between the ventilator, the window frame and the glass, and at the same time, after the ventilator is installed on the window frame, the lighting area will be reduced. Moreover, in order to install different ventilators, they must be designed separately, the structure is complicated, and the unity between the window frame and the ventilator cannot be realized in appearance, which makes the overall appearance unattractive

[0004] And in actual use, the place where the ventilator is installed is usually a noisy place, because the ventilator is installed to solve the ventilation problem caused when the glass is fully enclosed and installed for noise reduction. The problem of ventilation is considered. While ventilation is realized, due to the opening of the ventilation channel, the outdoor noise is again transmitted into the room through the channel, thus losing the purpose of noise reduction, and after the ventilator is closed, the indoor The problem of external heat insulation has not been solved accordingly
