Abstract
The utility model discloses a bidirectional ventilation tube. The utility model comprises an inner tube and an outer tube, wherein, both ends of a through-wall outer tube are respectively provided with a support sleeve for the inner tube, the inner tube is sheathed in the sleeve in an insertion way, and a protecting cover is arranged on the outlet end of the inner tube; an interlayer formed between the inner tube and the outer tube in a sheath way is favorable to air circulation and cold (hot) quantity exchange, the purpose of adjusting indoor air is realized, and fresh air is exchanged.
Description
The utility model relates to the improvement that room air is regulated facility, specifically is a kind of two-way scavenge trunk, and it belongs to the air conditioner facility technical field.
Using air-conditioner to carry out normally the door and window in room being closed tightly in the room air adjustment process, that carries out room air circulation adjusting so just causes the room air muddiness, make the people feel dizzy, dizzy, uncomfortable in chest, unsmooth breath, so that influence people's psychosomatic health.One wall ventilation fan is arranged, and it discharges indoor muddy air outdoor in scavenging period.This unidirectional air interchanger certainly will cause the loss of indoor more cold (heat) amount, and its ventilation effect is poor.
The purpose of this utility model is that a kind of two-way scavenge trunk will be provided.This pipe is simple in structure, installs easily, and easy to use, area occupied is little, energy savings, and ventilation effect is good.
Task of the present utility model has been developed a kind of two-way scavenge trunk by following technical scheme, and it comprises: interior pipe, and outer tube, the pipe support set is inserted with interior pipe, and is provided with protective cover at the port of export of interior pipe in this cover in the two ends of crossing the wall outer tube are respectively equipped with.
The pipe support set is provided with at least three disjunctor ribs in described between its pipe box outer wall and the outer tube wall, constitutes this cover and outer tube and is connected as a single entity, and the pipe box inwall of this cover is in direct contact with on the outer wall of inner tube, and inner chamber two end supports has outside been set up pipe in a section.
Described disjunctor rib, itself or axial straight rib strip, or axial screw rib, or grid-shaped rib.
Pipe in described, its pipe outer wall or be provided with screw thread and connect in the internal thread of interior pipe support set coupling; Perhaps two contact walls are the sliding fit connection.
Described protective cover, itself or have the calotte of wind-guiding valve, or have the calotte of end block gridiron.
Advantage of the present utility model has: (1) is simple in structure, adopts sleeve structure, utilizes the support set at outer tube two ends, supports interior pipe, makes the mezzanine space between the inner and outer pipes even, helps smooth and cold (heat) amount exchange of air.(2) easy for installation, area occupied is little, realizes two-way ventilation, fully energy exchange, energy savings.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the mounting structure schematic diagram of two-way scavenge trunk.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
Referring to Fig. 1--3, the two-way scavenge trunk of making is installed on the wall 7, and the indoor end 6 of this pipe is socketed on the ventilation fan.This pipe comprises: interior pipe 1 and outer tube 2.Pipe support set 3 in the two ends of crossing wall outer tube 2 are respectively equipped with.Interior pipe 1 is set in this cover 3, and is provided with the protective cover 5 of band screen frame end sealing cap cover at the air opening end (wall outer end) of interior pipe 1.The interior pipe support set 3 that is located at outer tube 2 two ends is connected admittedly at outer tube 2 two ends by grid-shaped rib 4, and is connected as a single entity with outer tube 2.The interior pipe 1 of this example is a male-pipe, internal thread coupling on the pipe box inwall of itself and this cover 3 links together, thereby constitutes the interlayer between the inner and outer pipe, is beneficial to the indoor-outdoor air heat exchange, make full use of the exchange heat between the air-flow of two-way flow, reach the effect of energy savings.
