Abstract

The utility model relates to a translation window for discharging chicken upper portion harmful gas to outdoors. The translation window for discharging the chicken upper portion harmful gas to the outdoors is characterized in that a wind board is arranged on the inner side of a window frame; a cavity chamber is formed in the upper portion of the wind board; an exhaust fan is arranged on the upper portion of one side of the window frame; the exhaust fan is connected with the window frame through a framework; a gap blocking plate is hinged to the lower portion of the framework. The utilization method of the translation window is that the exhaust fan is started, air inside a chicken is pumped to the outdoors through the cavity chamber which is arranged on the upper portion of the wind board; flow speed of the air close to the exhaust fan is accelerated and intensity of pressure is reduced, so that outside air with high intensity of pressure pushes the gap blocking plate to rotate toward a gap which is formed through the internal end surface of the exhaust fan and the internal end surface of an external side translation window, the gap blocking plate stops after touching the wind board, and the gaps are automatically blocked; when the exhaust fan stops rotating, the gap blocking plate falls according to self-weight, so that the window can be abnormally closed. The translation window for discharging the chicken upper portion harmful gas to the outdoors has the advantages of achieving gap blocking through pressure difference of the airflow and being capable of effectively discharging the harmful gas inside the chicken to the outdoors.

Description

A kind of translation window that the pernicious gas on top, kitchen can be discharged the open air

Technical field

The utility model relates to the dwelling house facility, particularly relates to a kind of translation window.

Background technology

At present, extract oil smoke in the kitchen out open air, normally used is smoke exhaust ventilator.But smoke exhaust ventilator is difficult to all take away rising the next oil smoke of rise on the kitchen range top, and the oil smoke that escapes into the smoke exhaust ventilator top is difficult to eliminate all the time, causes it to damage people's health.If exhaust fan is installed, then can will escape into the oil smoke discharge open air of smoke exhaust ventilator top with exhaust fan above smoke exhaust ventilator.But the body of wall in the kitchen is installed exhaust fan, then will destroy body of wall, and this is that administration departments institute is unallowed.How in the kitchen exhaust fan to be installed, to become a difficult problem.

The utility model content

At the problem that exhaust fan is installed in the kitchen, in order under the situation of not destroying the kitchen body of wall exhaust fan to be installed, the utility model provides a kind of novel translation window at window installation exhaust fan, and this translation window does not destroy original translation window yet.

The utility model is realized by following technical proposals: comprise outer sidesway window and interior sidesway window in the window frame of translation window, it is characterized in that setting up a verge board on the inner side edge of described window frame, the verge board surrounding is provided with the groove that matches with described inner side edge, and verge board top is provided with a cavity; Corresponding with described cavity, at a upper lateral part of described window frame one exhaust fan is set, exhaust fan is connected with window frame by framework, the lower hinge one stifled hollow plate of described framework; The inner face of exhaust fan flushes with the inner face of outer sidesway window and the inner face of framework;

Use the method for said apparatus: start exhaust fan, air in the kitchen is pumped to outdoor by the cavity on verge board top, because near the air velocity the exhaust fan is accelerated, pressure reduces, the space rotation that the stifled hollow plate of the high air push of external pressure forms to the inner face of the inner face of exhaust fan and outer sidesway window, stop the space of blocking automatically after running into verge board; After exhaust fan stopped operating, stifled hollow plate was sagging by deadweight, thereby did not influence the normal switching of window.

Usefulness of the present utility model is:

1, do not destroying body of wall, also do not destroying under the situation of original translation window, the oil smoke that exhaust fan do not siphon away by lampblack absorber in the kitchen can be installed in the kitchen discharge outdoor.

2, after exhaust fan is finished using, can close up translation window, guarantee that the kitchen is isolated from the outside.

3, utilize the pressure difference of air-flow to realize blocking automatically the space, thereby can more effectively the pernicious gas in the kitchen be discharged outdoor.

The specific embodiment

Further specify below in conjunction with the utility model of figure.

Referring to Fig. 1 and Fig. 6, Fig. 7, Fig. 8, the utility model is to set up a verge board 2 at the inner side edge 11 of the window frame 1 of the translation window of prior art; Verge board 2 surroundings are provided with the groove 22 that matches with inner side edge 11, make that verge board 2 can be mobile at inner side edge 11.Upper lateral part at window frame 1 arranges an exhaust fan 4, and exhaust fan 4 is connected with window frame 1 by framework 41.The inner face 42 of exhaust fan flushes (referring to Fig. 3 and Fig. 9) with the inner face 411 of the inner face 31 of outer sidesway window 3 and framework 41, so that interior sidesway window 5 can move freely in the window frame 1.Verge board 2 tops are provided with a cavity 21, and its size is basic identical with exhaust fan 4.State shown in Figure 10 is the state diagram when closing window, and just the kitchen isolates with extraneous, and exhaust fan 4 is not worked.

State shown in Figure 2 is the state diagram of exhaust fan 4 can work the time.With Figure 10 close the state of window different be that interior sidesway window 5 has been moved to the left a segment distance.At this moment, because the existence of verge board 2, the kitchen also isolates basically with extraneous, starts exhaust fan 4, and namely the noxious air in the kitchen can be sucked into the open air by exhaust fan 4 by cavity 21.Need to prove (referring to Fig. 3): after exhaust fan 4 started, air outside can creep into from the space 51 that verge board 2 and exhaust fan inner face 42 form, and for blocking space 51, blocked up hollow plate 43(referring to Fig. 4 in the lower hinge one of framework 41).(see figure 5) when exhaust fan 4 rotates, air in the kitchen is pumped to outdoor by the cavity 21 on verge board 2 tops, because near the air velocity the exhaust fan 4 is accelerated, according to bernoulli principle, flow velocity is accelerated, and pressure reduces, form low-pressure area, the stifled hollow plate 43 of the high air push of external pressure 51 rotates to the space, stop after running into verge board 2, thereby the space 51(that blocks automatically is referring to Fig. 5).After exhaust fan 4 stops operating, block up hollow plate 43 by deadweight sagging (referring to Fig. 4), thereby do not influence the normal switching of window.

Exhaust fan 4 preferably is electrically connected with the switch of smoke exhaust ventilator in the kitchen, and like this, when opening the smoke exhaust ventilator switch, smoke exhaust ventilator and exhaust fan 4 are worked together, and the pernicious gas in the kitchen is all discharged the open air.

State shown in Figure 9 is window state diagram when ventilating of the utility model.Indoor-outdoor air can circulate from space 9 and space 8.
