Description

The double air passage smoke exhaust ventilator

Technical field

The utility model belongs to the smoke exhaust ventilator technical field, more particularly, relates to the double air passage high efficiency fume exhaust device that a kind of existing exhaust gas flue has air inlet pipeline again.

Background technology

So far, all exhaustor for kitchen all adopt single air flue gas extraction system, all do not design air intake duct, so there is following phenomenon: 1, oil smoke is got rid of not thorough, still has residual indoor the causing indoor pollution of part oil smoke; Must open door or window when 2, using smoke exhaust ventilator, to guarantee that air-flow is unobstructed, especially to winter, indoor/outdoor temperature-difference is big, need door and window to close, when needs use smoke exhaust ventilator, must window or open the door, cause the person's of cooking diseases such as rheumatism, flu that are easy to get, otherwise it is indoor that air can enter from sewer, and smell is hard to bear; 3, for guaranteeing the pumping-clean rate of oil smoke is blindly strengthened the power of smoke exhaust ventilator, be unnecessary consumption to the energy.

The utility model content

Technical problem to be solved in the utility model is, 1, solved oil smoke and get rid of not thoroughly, still have the residual indoor difficult problem that causes indoor pollution of part oil smoke, and guaranteed the very pumping-clean rate of smoke exhaust ventilator to oil smoke; Must open door or window when 2, having solved the use smoke exhaust ventilator, otherwise that air can enter is indoor from sewer, the difficult problem that smell is hard to bear, air-flow is natural and tripping when having guaranteed to use smoke exhaust ventilator; 3, energy-conserving and environment-protective have solved and have blindly strengthened smoke exhaust ventilator power and can not realize the very difficult problem of pumping-clean rate.

The utility model double air passage smoke exhaust ventilator is achieved by following proposal, the housing of smoke exhaust ventilator two-layerly is made of inside and outside, inner housing and shell body are connected and fixed by bolt in the bottom, one mezzanine space is set between inner housing and shell body, hard-wired pumping-unit motor, fan and smoke exhaust ventilator exhaust gas flue are set in this space, one port of this gas flue is arranged at the smoke-box that inner casing shrouds, it is the smoke exhaust ventilator smoking room, the another port is arranged at the top of shell, be connected to the outdoor of kitchen by flexible pipe, mouth of pipe operated by rotary motion is prevented blast cap; In cover top portion an admission line is set in addition, one port of this admission line is connected to the mezzanine space between inner casing and the shell, the other end is connected to the outdoor of kitchen by flexible pipe, outdoor mouth of pipe operated by rotary motion hoop cover screen pack is provided with the butterfly valve that opened and closed by outer handle control in admission line; The aperture that one circle is communicated with mezzanine space is set around the side lower part of smoke exhaust ventilator shell; At the dorsal part top of shell fixedly suspension bracket of smoke exhaust ventilator is set; Lowest part setting at smoke exhaust ventilator connects lubricating cup.

The utlity model has following beneficial effect:

1, energy-conserving and environment-protective make smoke exhaust ventilator thoroughly be through with smoke exhaust ventilator by the high-power history that improves pumping-clean rate by double air passage self-loopa pattern, make smoke exhaust ventilator enter brand-new energy-conservation epoch.

2, solved oil smoke and got rid of not thoroughly, still have the residual indoor difficult problem that causes indoor pollution of part oil smoke, guaranteed the very pumping-clean rate of smoke exhaust ventilator to oil smoke.

Must open door or window when 3, having solved the use smoke exhaust ventilator, otherwise that air can enter is indoor from sewer, the difficult problem that smell is hard to bear, air-flow is natural and tripping when having guaranteed to use smoke exhaust ventilator.

4, simple and reasonable, be easy to install.

Description of drawings

Fig. 1 is a vertical section structure schematic diagram of the present utility model.

The specific embodiment

Below respectively in conjunction with the accompanying drawings 1 pair of the utility model be further described.The housing of smoke exhaust ventilator two-layerly is made of inside and outside, inner housing 2 is connected and fixed by bolt 13 in the bottom with shell body 1, one mezzanine space is set between inner housing and shell body, hard-wired pumping-unit motor, fan and smoke exhaust ventilator exhaust gas flue 4 are set in this space, one port 3 of gas flue 4 is arranged at the smoke-box that inner casing shrouds, i.e. smoke exhaust ventilator smoking room, and the another port is arranged at the top of shell, be connected to the outdoor of kitchen by smoke evacuation flexible pipe 8, mouth of pipe operated by rotary motion is prevented blast cap 10; In cover top portion an admission line 5 is set in addition, one port of admission line 5 is connected to the mezzanine space between inner casing and the shell, and be communicated with mezzanine space, the other end is connected to the outdoor of kitchen by air induction hose 9, outdoor mouth of pipe operated by rotary motion hoop cover screen pack 11, setting can be subjected to the butterfly valve 7 that outer handle 6 controls open and close in admission line 5; The air admission hole 15 that one circle is communicated with mezzanine space is set around the side lower part of shell; Fixedly suspension bracket 12 of smoke exhaust ventilator is set at the dorsal part top of shell; Lowest part setting at smoke exhaust ventilator connects lubricating cup 14.

As shown in Figure 1, operation principle of the present utility model:

Opening smoke exhaust ventilator when needs cooks, when cooking, at first close the door and window in the kitchen, open the butterfly valve in the air inlet pipe of smoke exhaust ventilator by handle, closed again smoke exhaust ventilator power switch, smoke exhaust ventilator is started working, under the suction of smoke exhaust ventilator, oil smoke and the room air that is produced of cooking discharged from flue, just can produce draught head with outdoor in the kitchen, so, outdoor air just successively passes through admission line, the lampblack absorber interlayer, the aperture that passes the lampblack absorber outer casing underpart enter into be forced to flow to after indoor be discharged to oil smoke behind the smoke exhaust ventilator smoking room outdoor, reciprocation cycle in this way, so, around smoke exhaust ventilator, form automatic cyclone, the oil smoke beyond the scope of shrouding of will wafing to smoke exhaust ventilator take in the lump be discharged in the lump behind the oil suction smoke-box outdoor, the distinctive feature of Here it is double air passage lampblack absorber, this is that the single flue smoke exhaust ventilator is incomparable, and such design is the clean absorption rate height not only, and laborsaving, thereby economize the purpose that merit reaches energy-conserving and environment-protective.

The utility model has utilized the operation principle of double air passage gas circulation cleverly, has both accomplished energy-conserving and environment-protective, has guaranteed the clean absorption rate of smoke exhaust ventilator again, many troubles that the user is run into have in use been solved simultaneously again, its appearance will produce revolution for the smoke exhaust ventilator industry
