Abstract
The utility model discloses an air supplement type fume hood, and belongs to laboratory ventilating devices. The air supplement type fume hood comprises a hood body which is provided with an air outlet and an air inlet. The air supplement type fume hood further comprises an air supplement motor. A movable tuyere is arranged below an operating door on the hood body, the operating door is further connected with a circuit switch of the air supplement motor, and the circuit switch is used for starting the air supplement motor simultaneously when the operating door is opened. A plurality of guide plates are further arranged between the air outlet and the air inlet. The air supplement mode that the movable tuyere below the operating door and the air supplement motor are matched with each other is used, so that outdoor fresh air does not contact with indoor air any more when the fume hood conducts air supplement, an indoor temperature is prevented from receiving fluctuations, and meanwhile experimenters are prevented from being influenced by various harmful gas in experiments. Meanwhile, the air supplement type fume hood is simple in structure, suitable for industrial production, suitable for being mounted and used in various experimental places, and wide in application range.
Description
Technical field
The utility model relates to a kind of laboratory ventilation equipment, and in particular, the utility model relates generally to a kind of air-replenishing type ventilating cabinet.
Background technology
vent cabinet generally is used for the laboratory, its Main Function is in time to discharge the pernicious gas that produces in the laboratory, and provide supply socket required in the laboratory, a kind of laboratory common equipment of cleaning function, and existing laboratory hood benefit wind is yard piping coupled logical at present, structural design by the furred ceiling air outlet is to the new wind of indoor benefit, outdoor new wind with discharge through vent cabinet again after room air mixes, thereby realize aforesaid ventilation effect, but due to the mode of its ventilation for new wind is mixed mutually with room air, therefore easily cause fluctuations in indoor temperature larger, thereby increase the energy consumption of room conditioning facility, be necessary again on this basis, do further improvement.
Summary of the invention
One of the purpose of this utility model is to solve above-mentioned deficiency, and a kind of air-replenishing type ventilating cabinet is provided, and solves with expectation and easily causes fluctuations in indoor temperature larger when in prior art, vent cabinet is mended wind, increases the technical problems such as air conditioner facility energy consumption.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of air-replenishing type ventilating cabinet provided by the utility model, comprise cabinet, described cabinet is provided with exhaust outlet and air inlet, described vent cabinet also comprises the benefit wind turbine, and the below of the actuating doors on cabinet is provided with movable air port, and actuating doors also is connected with the contactor of mending wind turbine, is used for starting when actuating doors is opened mending wind turbine; Also be provided with deflector between described exhaust outlet and air inlet.
As preferably, further technical scheme is: the movable air port of described actuating doors below is shutter.
Further technical scheme is: described movable air port is connected with air inlet by the secondary air channel road, and described benefit wind turbine be arranged on air inlet near, be used for new wind is entered by air inlet.
Further technical scheme is: described secondary air channel road is on the inwall that is arranged on cabinet of hidden.
Compared with prior art, one of the beneficial effects of the utility model are: by adopting actuating doors underside air port and mending the benefit wind mode that wind turbine cooperatively interacts, vent cabinet outdoor new wind when mending wind is no longer contacted with room air, avoid indoor temperature therefore to be fluctuateed, also avoid simultaneously the experimenter to be subject to the impact of various pernicious gases when experiment, a kind of air-replenishing type ventilating cabinet provided by the utility model is simple in structure simultaneously, be suitable for suitability for industrialized production, and be suitable for installing and using in all kinds of experiments places, range of application is wide.
Description of drawings
Fig. 1 is for being used for the structural representation of an embodiment of explanation the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
With reference to shown in Figure 1, an embodiment of the present utility model is a kind of air-replenishing type ventilating cabinet, comprise cabinet 1, described cabinet 1 is provided with exhaust outlet and air inlet, described vent cabinet also comprises the benefit wind turbine, and 3 belows of the actuating doors on cabinet 1 are provided with movable air port 2, and actuating doors 3 also is connected with the contactor of mending wind turbine, are used for starting when actuating doors 3 is opened and mend wind turbine; Also be provided with deflector between described exhaust outlet and air inlet.
According to another embodiment of the present utility model: the movable air port 2 of aforesaid operations door 3 belows is shutter.
The utility model is used for solving the problems of the technologies described above, and an embodiment who is more preferably is: above-mentioned movable air port 2 is connected with air inlet by the secondary air channel road, and described benefit wind turbine be arranged on air inlet near, for new wind is entered by air inlet.And the secondary air channel road is on the inwall that is arranged on cabinet 1 of hidden.
and the utility model the above embodiments to be implementations be: blinds movable air port is set below the actuating doors 3 of vent cabinet, and be connected with outdoor air inlet by concealed secondary air channel road, when opening the vent cabinet air draft, the user starts simultaneously the benefit wind turbine, outdoor new wind forms upwards gas curtain by the blinds of actuating doors 3 belows movable air port, directly mend new wind in vent cabinet, again in this process, the interior original air of cabinet 1 is discharged outdoor by exhaust outlet rapidly, the new wind that fills into is not mixed with indoor air, reduced indoor original air discharge, thereby reduce the room conditioning energy consumption more than 30%.
On the basis of above-described embodiment, also need to prove " embodiment ", " another embodiment ", " embodiment " that speak of in this manual, etc., refer to specific features, structure or the characteristics described in conjunction with this embodiment and be included at least one embodiment that the application's generality describes.A plurality of local appearance statement of the same race is not necessarily to refer to same embodiment in specification.Furthermore, when describing a specific features, structure or characteristics in conjunction with arbitrary embodiment, what advocate is to realize that in conjunction with other embodiment this feature, structure or characteristics also drop in scope of the present utility model.
Although with reference to a plurality of explanatory embodiment of the present utility model, the utility model is described here, but, should be appreciated that, those skilled in the art can design a lot of other modification and embodiments, and these are revised and within embodiment will drop on the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes will be also obvious.
