Abstract
The utility model discloses a labyrinth ventilator, wherein at least two groups of wind baffle plates (2) which are capable of moving back and forth in an opposite way are alternately arranged in an outer frame (1) of the ventilator. As air enters a room through the labyrinth ventilator, external noise and heat are sufficiently weakened and obstructed through the tortuous flow passage, the requirements of thermal insulation and noise reduction are met while the requirement on ventilation is met, and the alternately-arranged wind baffle plates greatly improve the water-tightness of the whole ventilator which has a simple structure and is economical and suitable.
Description
Technical field
The utility model relates to a kind of ventilator, is specifically related to the windshield plate of ventilator.
Background technology
The windshield plate of the tradition ventilation device that adopts on the existing market is typically designed to the pendulum-type windshield plate, air door is opened or is closed in its swing by windshield plate, so that the air in the inlet chamber is controlled, when air door is being opened, extraneous noise and heat will enter into indoor along with air together by air door, therefore this ventilator not only can't satisfy the requirement of ventilation, heat insulation and noise reduction three aspects simultaneously, and its watertightness is also relatively poor.
At above-mentioned deficiency, the ventilator that has is arranged on air inlet the bottom of ventilator, promptly from the bottom air inlet of ventilator, make the air that enters ventilator just can enter into indoor by half-twist, therefore, this ventilator windage is bigger, tends to cause the runner loss to increase considerably, and will influence the air capacity in the inlet chamber when gravity-flow ventilation greatly.
The utility model content
At above-mentioned deficiency, the utility model provides a kind of labyrinth type ventilator, and this ventilator not only can satisfy the requirement of ventilation, heat insulation and noise reduction three aspects simultaneously, and reduces windage when guaranteeing to have good watertightness.
The purpose of this utility model is achieved through the following technical solutions:
A kind of labyrinth type ventilator, this ventilator is provided with at least two group interlaced arrangement and can moves forward and backward relatively in its housing windshield plate, wherein certain group or a few groups of windshield plates are set to fixed stop herein, the wind shelves of other groups are set to move retaining, should move retaining moves forward and backward with respect to fixed stop, so that air quantity is controlled, comprise unlatching, close, increase and reduce the control of air quantity; Also every group windshield plate all can be set to move retaining.
Described windshield plate is " V " type, every group of windshield plate towards identical, and the two adjacent groups windshield plate towards on the contrary, back-off is arranged thereby per two groups of windshield plates can interlock, so that better the air air quantity is controlled; Certainly, the shape of windshield plate also can be provided with as the case may be, such as being set to circle, triangle or other shapes.
In order to prolong the path in the air inlet chamber, make the air must be through in could inlet chamber behind the full of twists and turns path, described windshield plate is provided with more than 4 groups or 4 groups, it is parallel or perpendicular to the axis of described ventilator, and it is parallel in twos between every group of windshield plate, thereby air is when this mazy path, and the noise and the heat in the external world are fully intercepted by this path, reaches the purpose of ventilation, heat insulation and noise reduction better.
The labyrinth type ventilator that the utility model provides is for traditional ventilator, the windshield plate that it is provided with at least two group interlaced arrangement and can moves forward and backward relatively, therefore, outside air turns round the back repeatedly and enters with the situation of rotating when directly introducing is indoor, air must half-twist in the tradition ventilation device, its windage reduces greatly, outdoor noise and heat are fully weakened by full of twists and turns runner and intercept in this process, when satisfying ventilation, also taken into account heat insulation and requirement noise reduction, and the windshield plate of this interlaced arrangement has improved the watertightness of whole ventilator greatly; Secondly, this ventilator need not the mosquito net of setting up defences in addition, also can play the effect of good mosquito proof; Further be, this ventilator is specially adapted to windy and dusty area, and its special labyrinth path that is provided with can be thrown to the bulky grain sandy soil inwall of runner under action of centrifugal force, and the bottom is discharged outdoor along this inwall landing to ventilator, it is simple in structure, and is economic and practical.

Fig. 1 is the layout Pareto diagram and the air flow figure of windshield plate during labyrinth type ventilator door opening among the utility model embodiment.
The layout Pareto diagram of wind plate washer when Fig. 2 closes for labyrinth type ventilator air door.
The specific embodiment
For the beneficial effect of understanding technical problem to be solved in the utility model, the technical scheme that is adopted better and being reached, come the utility model is further specified below in conjunction with embodiment; Need to prove that each technical characterictic in following examples all is a representative of other equivalences or similar technical characteristics, it is not limited to the utility model scope required for protection in following examples; And involved new technical characterictic or combination in the utility model specification, or involved new method or step all will drop within the desired protection domain of the utility model.
As depicted in figs. 1 and 2, a kind of labyrinth type ventilator, this ventilator are provided with the 4 groups of interlaced arrangement and the windshield plate 2 that can move forward and backward relatively in its housing 1, and it is parallel to the axis of ventilator, and parallel in twos between every group of windshield plate 2; Described windshield plate 2 is " V " type, every group of windshield plate 2 towards identical, and two adjacent groups windshield plate 2 towards on the contrary, 3 groups of windshield plates near the air inlet direction are set to fixed stop, 1 group near indoor direction is mobile retaining, and this moves retaining and can move forward and backward with respect to fixed stop under external force drives, so that the air air quantity is controlled, when promptly mobile retaining moved away from fixed stop, air quantity increased gradually; When moving retaining near the fixed stop motion, air quantity reduces gradually; When moving retaining with the fixed stop back-off, air quantity is closed, and the flow direction of air is asked for an interview shown in the arrow among Fig. 1.
Claims (3)
1. a labyrinth type ventilator is characterized in that: this ventilator is provided with two group interlaced arrangement and can moves forward and backward relatively in its housing (1) windshield plate (2) at least.
2. labyrinth type ventilator as claimed in claim 1 is characterized in that: described windshield plate (2) is " V " type, every group of windshield plate (2) towards identical, and two adjacent groups windshield plate (2) towards on the contrary.
3. labyrinth type ventilator as claimed in claim 2 is characterized in that: totally 4 groups of described windshield plates (2), it is parallel or perpendicular to the axis of ventilator, and parallel in twos between every group of windshield plate (2).
