Abstract
The utility model discloses a simple ventilation and air exchange device for a cave dwelling. The simple ventilation and air exchange device comprises a ventilation pipeline and an exhaust fan, wherein the ventilation pipeline is formed by connecting an indoor pipeline with an outdoor pipeline; the exhaust fan is positioned on the end part of the indoor pipeline; and the end part of the outdoor pipeline is provided with a bent pipe opened downwardly. The simple ventilation and air exchange device mainly comprises the ventilation pipeline and the exhaust fan, has a simple structure, is low in manufacturing cost, is easy to install, and is easy for popularizing on a large scale. The simple ventilation and air exchange device is arranged in an electrified cave, the exhaust fan is used for exhausting gas in the cave from the ventilation pipeline to the outside, and fresh air enters a room through a door and a window of the cave under the action of a negative pressure, so that clean air in the cave is kept.
Description
Technical field
The utility model belongs to air interchanger, relates in particular to a kind of simple and easy compound ventilation air-changing device that is used for cave-dwelling.
Background technology
China's cave dwelling is the characteristic of utilizing loess to stand like a wall not fall and the arch of the excavating formula dwelling house of living in caves, and mainly is distributed in the loess area in provinces such as Shaanxi, Gansu, Inner Mongol, Shanxi, Henan, Qinghai.As a kind of important local-style dwelling houses form, cave dwelling occupies an important position in the historical development of China always, still has more than 4,000 ten thousand people to live in the cave dwelling in northern China so far,
Cave dwelling is condensing the loess plateau people's wisdom and building experience; Not only cool in summer and warm in winter; And energy-conservation, save land, shockproof, dustproof, windproof, anti-riot, sound insulation, clean, quiet, gather materials on the spot, be easy to construction, cheap; Help the ecological balance and protect original natural land, a kind of really " green " construction style of suiting measures to local conditions.
But also have some shortcomings, it is poor that one of shortcoming is exactly the ventilation situation.Reason is: only have single face to offer door and window in the kiln, the formula of can't passing through is ventilated, and can not guarantee that indoor-outdoor air fully exchanges, and causes foreign flavor indoors bigger, and carbon dioxide, Dust Capacity all exceed standard, and indoor humidity is bigger, is prone to cause that corner etc. locates mould and multiply.
Some imaginations of ventilating had also appearred in recent years; As punch top and side, but owing to cave dwelling generally digs at the place, hillside, so its " roof " is all quite thick with " wall "; If punch top and side; Not only great in constructing amount, and can destroy the massif soil layer construction, so this imagination is unworkable basically.Also the someone had adopted underground ventilation and air conditioning system in recent years, but this form is great in constructing amount, and cost is higher, promoted being restricted on a large scale.
Summary of the invention
The purpose of the utility model provides a kind of simple and easy compound ventilation air-changing device that is used for cave-dwelling, has the advantage that cost is low, simple in structure, be prone to installation, be easy to promote on a large scale.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of simple and easy compound ventilation air-changing device that is used for cave-dwelling; Comprise ventilation shaft and exhaust fan; Described ventilation shaft is formed by connecting interior conduit and yard piping, and exhaust fan is positioned at the end of interior conduit, and the bend pipe under shed is equipped with in the end of yard piping.
Described yard piping is formed by connecting vertical tube and transverse tube, and described bend pipe is contained in the end of transverse tube.
Described interior conduit is formed by connecting standpipe and trunk line, and trunk line links to each other with the vertical tube of yard piping.
The end of standpipe also has a casing, and exhaust fan is positioned at casing, and air admission hole is arranged on the casing.
The utility model mainly is made up of ventilation shaft and exhaust fan, and is simple in structure, cheap, and easy mounting, is easy to promote on a large scale.The utility model is installed in the cave dwelling of having switched on and uses, and exhaust fan is discharged to the gas in the cave dwelling outdoor from ventilation shaft, because action of negative pressure, fresh air is in the door and window inlet chamber of cave dwelling, thus the air cleaner in the maintenance cave dwelling.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The simple and easy compound ventilation air-changing device that is used for cave-dwelling as shown in Figure 1; Comprise ventilation shaft and exhaust fan 3; Ventilation shaft is formed by connecting interior conduit and yard piping, and exhaust fan 3 is positioned at the end of interior conduit, and the bend pipe 8 under shed is equipped with in the end of yard piping.Yard piping is formed by connecting vertical tube 6 and transverse tube 7, and bend pipe 8 is contained in the end of transverse tube 7.Interior conduit is formed by connecting standpipe 4 and trunk line 5, and trunk line 5 links to each other with the vertical tube 6 of yard piping.The end of standpipe 4 also has a casing 1, and exhaust fan 3 is positioned at casing 1, and air admission hole 2 is arranged on the casing.
The utility model when mounted, the casing 1 that exhaust fan is housed is close to the cave dwelling rear wall with standpipe 4, standpipe 4 is positioned at cave dwelling rear wall centre vertically upward; Trunk line 5 is close to the cave dwelling roof in the middle, runs through whole cave dwelling; 1 meter of vertical tube 6 length are close to the cave dwelling outer wall vertical upwards; Transverse tube 7 long 3 meters or the longer cave dwelling outer walls of being close to, level is to the right or left, its effect is to prevent that effluent air from passing through in the door and window backflow cave dwelling; The effect of bend pipe 8 is rainproof.During use, the exhaust fan rotation utilizes negative pressure with gas suction pipeline in the cave dwelling, and gas flows out cave dwelling through pipeline, and fresh air gets in the cave dwelling from the door and window of cave dwelling, thereby keeps the air cleaner in the cave dwelling.
