Description

A kind of library ventilated bookshelf

Technical field

Patent of the present invention relates to the bookshelf that library uses, and relates in particular to the bookshelf with ventilation unit.

Background technology

In the collected books in library existing new book with secondhand book arranged.New book often has very heavy printing ink smell, though and contain some people's news (smelling) of bringing less than other nuisances that are unfavorable for health of people in the printing bookbinding process.Secondhand book is crossed for a long time and is left in because of the resting period in the environment that the stack room in library draw badly, so, usually again all with various moulds.Especially cross just someone expired books and magazine of consulting of several years, can smell one dense musty once taking out.Therefore, people are except for stack room itself, strengthening venting practice, also have directly and to increase ventilation unit putting on the bookshelf of book.For example, publication number is CN101438897A, and name is called the patent application of " ventilated bookshelf ", has just increased on the shelf ventilation unit.This ventilated bookshelf retains the bookshelf inherent structure except basic, also the inside panel of its bookshelf lattice is all become to " orifice plate ", at " orifice plate ", be provided with a negative pressure chamber (this patent application is called " air duct ") behind, this negative pressure chamber and " airduct " communicates, and should " airduct " pass to outdoor; And, in its " airduct ", also be mounted with by " frequency conversion exhaust blower ".Only from ventilating and the dedusting angle, the prior art truly have good effect.Yet because air-conditioning has all been installed in present library usually, bookshelf also is placed in air-conditioned reading room mostly; For convenience of people, carefully search, air-conditioning even also is installed in stack room.When " orifice plate " exhaust, although strengthened, ventilate and dust be discharged into outdoor by " airduct ", also taken at the same time a large amount of cold air (or the hot gas in winter) away.So, not only waste a large amount of energy, but and polluted external environment when the bookshelf dedusting.

Summary of the invention

The technical problem to be solved in the present invention is that the deficiency for prior art exists, provide a kind of and can save the energy, and can not pollute library's ventilated bookshelf of external environment.

The technical scheme solve the technical problem is a kind of like this library ventilated bookshelf, aspect same as the prior art is, it has the inboard some layers of book supporting board on backboard that all lean against, corresponding part at backboard and each layer book supporting board all has wind inlet, in the backboard back, be a negative pressure chamber, this negative pressure chamber with one in have the air channel of air exhauster to be communicated with.Its improvements are, described backboard has back-to-back symmetrically arranged two, and negative pressure chamber is clipped between these two backboards; Described air channel in negative pressure chamber top and by air-duct clapboard and negative pressure chamber, separate, the inlet scoop, air channel that the bottom Shi Yu negative pressure chamber in this air channel is communicated with, the top in this air channel is the lid that binds with two sidewall panelings, on these two sidewall panelings, all have exhaust vent, all there is the filter that blocks exhaust vent inboard at these two sidewall panelings, and this filter clips layer of active carbon by two-layer screen pack and framework forms; Described air exhauster is the frequency conversion type cross flow fan, and this frequency conversion type cross flow fan is arranged between two filters.

From scheme, finding out, the present invention has not extended to the air outlet in air channel outdoor as prior art, but (its quantity obviously should be enough) exhaust vents that will be equivalent to air outlet be arranged on library with the top of ventilated bookshelf (from scheme, finding out, with two sidewall panelings that binding of exhaust vent covered, all in library, use the top of ventilated bookshelf), all there is the filter that blocks exhaust vent inboard due to two sidewall panelings again, and active carbon is arranged in filter, so, when the present invention being placed in while being with air-conditioned reading room or stack room, not only can not take cold air (or the hot gas in winter) away, and, from exhaust vent, be emitted on indoor, and then the air while flowing to again the collected books part on book supporting board is also clean.Also namely, in this road of the inboard of wind inlet → negative pressure chamber → air channel → filter, the dust blown away with the collected books from book supporting board in its air flowed and the peculiar smell of taking away; In the outside → exhaust vent of filter → reading room or stack room → this road before collected books on book supporting board in, by charcoal absorption, dust is filtered net filtration and has fallen, so its air flowed is but clean due to various peculiar smell.Therefore, compared with prior art, the present invention not only can take away dust and the peculiar smell on collected books equally, but also has saved the energy, also not to external world environment cause new pollution.

In addition, because the air exhauster in the present invention has adopted the frequency conversion type cross flow fan, and backboard (and book supporting board) adopted back-to-back being symmetrical arranged, and therefore, can also reduce the degree increased because of this bookshelf thickness that the negative pressure chamber that arranges etc. causes.

The present invention is further illustrated below in conjunction with accompanying drawing.

The specific embodiment

A kind of library ventilated bookshelf (with reference to figure 1,2,3), it has the inboard some layers of book supporting board 1 on backboard 8 that all lean against, at backboard 8 and the corresponding part of each layer book supporting board 1, wind inlet 6 being arranged all, is negative pressure chamber in backboard 8 back, this negative pressure chamber with one in have the air channel of air exhauster 2 to be communicated with.In the present invention, described backboard 8 has back-to-back symmetrically arranged two, and negative pressure chamber is clipped between these two backboards 8; Described air channel in negative pressure chamber top and by air-duct clapboard 4, separate with negative pressure chamber, the inlet scoop, air channel 41 that the bottom Shi Yu negative pressure chamber in this air channel is communicated with, the top in this air channel is the lid that binds with two sidewall panelings, on these two sidewall panelings, all have exhaust vent 5, all there is the filter that blocks exhaust vent 5 inboard at these two sidewall panelings, and this filter clips layer of active carbon 52 by two-layer screen pack 51 and framework 53 forms; Described air exhauster 2 is the frequency conversion type cross flow fan, and this frequency conversion type cross flow fan is arranged between two filters.

It will be apparent to those skilled in that, the quantity of wind inlet 6 and exhaust vent 5 should be enough, take can as often as possible remove dust and peculiar smell is degree.Due to use and the corresponding control circuit of frequency conversion type cross flow fan, by those skilled in the art, known already, so, at this, disclose no longer in detail.

Disclosure is arrived this, the understanding of those skilled in the art to beneficial effect of the present invention, and one designs and manufactures substantially the same with the present invention library surely comes with ventilated bookshelf.

Below disclose the further improvement that can obtain better effect.

For guaranteeing the cleaned air blown out from exhaust vent 5, can either comparatively fast flow to each wind inlet 6, be unlikely to again to blow to the reader and it is felt under the weather, should allow the air blown out from exhaust vent 5 be inclined upwardly, corresponding two sidewall paneling angles of inclination with respect to the horizontal plane are between 45 °～60 °.That is to say, the distance between two sidewall panelings, be top near below (with reference to figure 2) far away.

The present invention can use equally in some stack room that do not install an air-conditioner, in order to guarantee that collected books in this case can have a suitable humiture environment, within the inlet scoop 41 in air channel, heat exchanger 3 is installed, this heat exchanger 3 is the heat exchangers in the pump type heat split-type air conditioner indoor set; Below inlet scoop, air channel 41, a drip tray 7(is arranged with reference to figure 2).

When being only the stack room excess Temperature, starting this heat exchanger 3 and allow its refrigeration, cooling; When the stack room temperature and humidity is all too high, starts this heat exchanger 3 and allow it both freeze, to lower the temperature, again dehumidifying.The condensed water that refrigeration and dehumidifying produce all falls in drip tray 7 (obviously, the condensed water of depositing at drip tray 7 should emit, and due to obvious, in figure, does not draw discharge structure).

Because the pump type heat split-type air conditioner is known by those skilled in the art already, so, relate to temperature sensor, the humidity sensor mated with heat exchanger 3, the off-premises station that is equivalent to the pump type heat split-type air conditioner, and control device etc., all do not draw in the accompanying drawings, here do not do to disclose in detail yet.

For convenience of filter is cleaned and/or changes, can further it be designed and manufactured into to dismountable structure.Concrete structure is (with reference to figure 4): exhaust vent 5 parts and filter on sidewall paneling are the filter assemblies combined, and this transition assembly consists of the cover plate 50 with exhaust vent 5 and the filter that is fixed on these cover plate 50 inboards; On sidewall paneling, be with the hole that can be covered fully by cover plate 50, this cover plate 50 covers on this hole regularly by screw; The outer side edges of this hole along and the opposite face of cover plate 50 between accompany sealing gasket 54.

Obviously, between filter and cover plate 50, can be both that the former embeds or buckle into the back side the latter, can be also by screw, both connections to be got off.It is equally evident that, also the lid that binds to whole air channel can be made to dismountable structure.
