The specific embodiment
To shown in Figure 5, supply/discharge type ventilator comprises in the time of present embodiment by Fig. 1: framework matrix 14, the air feed fan (hereinafter referred to as fan) 9 and the exhaust fan (hereinafter referred to as fan) 10 that constitute main body 50.For framework matrix 14, it has respectively with air feed air channel 4 that forms by the spacer portion 6 in the double-layer tube 3 that connects chamber interior walls 2 and exhaust duct 5 and is communicated with also adjacent outside air supply opening 7 and outside exhaust outlet 8, and this framework matrix 14 is provided on the chamber interior walls 2.Fan 9 is set at the inside of the main body 50 of being surrounded by framework matrix 14 and shutter 1, is used for to the indoor air feed.That is, from outside air supply opening 7 to indoor air supply opening 11,12 supply gas.Fan 10 is set at fan 9 sides, is used for carrying out exhaust to the outside.That is, discharge gas to outside 8 from indoor exhaust outlet 13.
Indoor air supply opening 11,12 is set to be communicated with outside air supply opening 7 by fan 9.Indoor air supply opening 11 be set at shutter 1 above, indoor air supply opening 12 is set at the top of the front of shutter 1.Indoor exhaust outlet 13 with the mode that is communicated with outside exhaust outlet 8 by fan 10 be arranged at shutter 1 below.The inside of main body 50 is separated into exhaust channel 30 and air feed path 40 by air channel spacer portion 19 and connected rake 30A, 30B, and fan 9 is oppositely arranged with air feed path 40, is oppositely arranged in fan 10 and the exhaust channel 30.
At first, closing with the optimum position in the fan 9 relative with air feed path 40, outside air supply opening 7, air feed air channel 4 is main describing. Set fan 9,10 with the rotating shaft 9A of fan 9 and the relative mode that is vertical direction with wall chamber interior walls 2 of rotating shaft 10A of fan 10 side by side in wall direction along chamber interior walls 2.In general, being shaped as of fan, the direction ratio vertical direction parallel with its rotating shaft is long.Thus, set fan at 9,10 o'clock relatively with framework matrix 14, if the suction inlet of each fan almost is parallel shape along the wall of chamber interior walls 2, then fan is little to the outstanding length of indoor.That is, main body 50 is little to the outstanding thickness in indoor.
At the state of the chamber interior walls 2 by main body 50 is set, when being installed in main body 50 on the chamber interior walls 2, separately rotating shaft 9A, the 10A of fan 9,10 are set to the result and slightly tilt from the vertical direction of relative chamber interior walls 2 sometimes.In addition,, also exist rotating shaft 9A, 10A slightly to tilt, constitute the situation of main body 50 from relative chamber interior walls 2 vertical directions according to this design.Even under these circumstances, each suction inlet 31A, the 31B that is arranged on the fan 9,10 in the main body 50 becomes when the wall of chamber interior walls 2 is almost parallel state, is also contained in the scope of this structure.
In addition, as shown in Figure 2, from when the direction of chamber interior walls 2 is faced main body 50, the center of double-layer tube 3 is provided between the rotating shaft 10A of the rotating shaft 9A of fan 9 and fan 10, near rotating shaft 9A side.In Fig. 2, rotating shaft 9A is provided in the approximate centre position of outside air supply opening 7, but also can be provided in than this position more the top or more the below the position.So set double-layer tube 3 and can increase air quantity.Below, specify this effect.
When being configured in the position of 40mm, the air feed air quantity is 29.3m
3/ h, exhaust air quantity are 25.6m
3/ h.When being configured in the position of 55mm, the air feed air quantity is 30.5m
3/ h, exhaust air quantity are 26.0m
3/ h.That is, under the situation of 55mm, the situation of relative 40mm, air feed air quantity increment rate is 4.1%, exhaust air quantity increment rate is 1.6%.Need not describe in detail, near fan 9, too, spacer portion 6 increases apart near the near more then air quantity fan 9 double-layer tube 3 when 0mm changes in the scope of 40mm from the centre position of rotating shaft 9A, 10A.From above result as can be known, when when chamber interior walls 2 is faced main body 50, outside air supply opening 7 preferred disposition that are communicated with the air feed air channel 4 of double-layer tube 3 are near the rotating shaft 9A of fan 9.
In addition, when when chamber interior walls 2 is faced main body 50, rotating shaft 9A preferably set for: be contained in the opening of the outside air supply opening 7 that is communicated with the air feed air channel 4 of double-layer tube 3.Thus, the suction inlet 31A of fan 9 is set near the outside air supply opening 7 relative positions.Therefore, the air channel that can directly form through the suction inlet 31A of the fan 9 of associating is taken into outdoor air in the double-layer tube 3, obtains excellent air feed air quantity characteristic.In addition, be set near the positions relative the outside air supply opening 7 by suction inlet 31A with fan 9, and with outside exhaust outlet 8 be set in fan 9 near.Can guarantee the distance from the discharge opening of fan 10 to outside exhaust outlet 8 thus, guarantee the performance of fan 10, it is very approaching that fan 10 and fan 9 are configured to.Make the size decreases of main body 50 transverse directions thus.
In addition, as shown in Figure 2, the vertical direction in relative spacing portion 6, the maximum distance part 4A of the inner face from spacer portion 6 to air feed air channel 4 preferably constitutes the inboard of the suction inlet 31A that is contained in fan 9.The suction inlet 31A of fan 9 is arranged on the position relative with outside air supply opening 7.This position relation is being benchmark when chamber interior walls 2 is faced main body 50.In addition, the suction inlet 31A of fan 9 is arranged on the position relative with outside air supply opening 7.Thus, preferred double-layer tube 3 is oppositely arranged with main body 50.
Central portion by making outside air supply opening 7 and the suction inlet 31A of fan 9 near and relative, make near the outside of central portion of suction inlet 31A of fan 9 have outside air supply opening 7.Therefore, reduce the resistance in the suction air channel of the air feed stream that is taken in the double-layer tube 3.In addition, outside exhaust outlet 8 is arranged near the fan 9, therefore also can guarantee the performance of fan 10.
In addition, when when chamber interior walls 2 is faced main body 50, a part of opening of outside exhaust outlet 8 preferably is contained in the inboard of the suction inlet 31A of the fan 9 that is provided with outside air supply opening 7 relative positions.So design double-layer tube 3 makes outside exhaust outlet 8 be arranged near the deflection fan 9, and the exhaust channel that 10 discharge opening forms from outside exhaust outlet 8 to fan is elongated thus.Thus, increase the exhaust air quantity.
Wherein, when when chamber interior walls 2 is faced main body 50, a part that is arranged on the spacer portion 6 of double-layer tube 3 inside also can set in the mode in the opening of the suction inlet 31A that is contained in fan 9.In such structure, the exhaust channel 30 that 10 discharge opening forms from outside exhaust outlet 8 to fan is also elongated.In addition, the degree of depth of the main body 50 of the vertical direction of chamber interior walls 2 shortens relatively, and miniaturization also can form long exhaust channel 30 in the direction of chamber interior walls 2 inclinations relatively.Thus, can sharply not change the flow direction of exhaust stream and, increase the exhaust air quantity the air guided outboard row gas port 8 of entering the room.
In addition, when when chamber interior walls 2 is faced main body 50, the opening of the outside exhaust outlet 8 that is communicated with the exhaust duct 5 of double-layer tube 3 also can not be contained in the inboard of the suction inlet 31B of the fan 10 that is formed in the indoor.That is, outside exhaust outlet 8 can have not the suction inlet 31B superposed part with fan 10 at least.Main body 50 is provided with double-layer tube 3 relatively, outside exhaust outlet 8 is separated being provided with from fan 10.Therefore, the distance of the discharge opening of outside exhaust outlet 8 and fan 10 is elongated, and the exhaust air quantity increases.
In addition, the rotating shaft 10A of fan 10, preferred disposition is above the center line on the relative long limit of the longitudinal direction of framework matrix 14.That is, fan 10 preferred disposition in main body 50 near above.Its result, elongated from the indoor exhaust outlet 13 that below shutter 1, forms to the distance of the suction inlet 31B of fan 10.Therefore, for miniaturization, in the thickness attenuation of the main body 50 of the vertical direction of chamber interior walls 2, the interval of the suction inlet 31B of fan 10 and the front dorsal part of main body 50 diminishes, and can guarantee that also fan 10 is used to suck the suction space of room air.
In addition, the rotating shaft 10A preferred disposition of fan 10 is above the rotating shaft 9A of the fan on the longitudinal direction of main body 50 9.Thus, the exhaust channel from the discharge opening of fan 10 to outside exhaust outlet 13 can form long structure.
Then, structure in the main body 50 that forms air feed path 40, exhaust channel 30 is described.As shown in Figure 1, shutter 1 is resinous box shape, and the mode that contains fan 9,10 with side within it covers these fans from the place ahead.On shutter 1, the indoor air supply opening 11 of fan 9 is arranged on front face, and it is facial that indoor air supply opening 12 is arranged on, and offers these openings and the lower face on diagonal is offered indoor exhaust outlet 13.Thus, indoor air supply opening 11,12 and indoor exhaust outlet 13 relative main bodys 50 configured separate on diagonal.To the air feed of indoor supply stream with suck on the position that the exhaust stream of room air separates in main body 50 and form.Thus, the shortage of air feed stream and exhaust stream can be prevented, indoor ventilation can be carried out effectively.
Wherein, be provided with lock terminal 1A at two places of the side of shutter 1.Lock terminal 1A be arranged on lock terminal connector (not shown) on the framework matrix 14, be arranged on exhaust with the lock terminal connector 17B connection on the fan guard (below, be called cover) 17.Thus, shutter 1 is arranged on the indoor in the mode that can freely pull down.
In addition, indoor air supply opening 11 is arranged on the top of the front of shutter 1 with rectangle.Therefore, the non-aperture area of the front of main body 50 becomes big, forms the few shiny surface of jog, and dust etc. are difficult to adhere to, thus aspect excellences such as cleaning property, outward appearance.
The structure of exhaust side then, is described.As Fig. 1, shown in Figure 3, at the front of shutter 1 dorsal part, the one side has fan 10.The motor 10C of drive fan 10 across the flange portion that forms at its sidepiece by be bolted to exhaust with motor fixed head (below, be called fixed head) 15 on.Fixed head 15 is fixed on a plurality of protruding 14A that erects on the framework matrix 14 by bolt.Fixed head 15 remains on the place ahead that is provided with apart from predetermined distance from framework matrix 14 by protruding 14A.Dispose Denso shell 16 between fixed head 15 and the framework matrix 14.The display part etc. of on Denso shell 16, taking in the circuit substrate that drives the motor 9C that motor 10C that the control exhaust uses and air feed use, being used for the change-over circuit of strong and weak each fan of running and showing transition status.
In addition, fan 9,10 is a centrifugal fan, thus, can not damage exhaust performance, air feed performance and indoor exhaust outlet 13 and outside air supply opening 12 are arranged on the side of main body 50, so, can make main body 50 slimmings.
Fig. 5 is the side cross-sectional view of structure that is provided with main body 50 inside of fan 10 sides.As Fig. 1, Fig. 3 and shown in Figure 5,, suction inlet and discharge opening 31 are set as shown in Figure 1 to cover the shape of 17 covering fans 10.But cover 17 suction inlet has symbol is not shown, in fact with the suction inlet 31B basically identical of fan 10.Exhaust channel 30 forms through outside exhaust outlet 8 from covering 17 discharge opening 31.Exhaust channel 30 is preferred between the fan 9 and chamber interior walls 2 of the side of being located at fan 10.In this structure, fan 10 can be configured near the fan 9, make the lateral dimension of main body 50 diminish.
In addition, on the sidewall (prolongation of air channel spacer portion 19) of fan 9 sides of exhaust channel 30, be preferably formed towards outside exhaust outlet 8, the rake 30A, the 30B that tilt of chamber interior walls 2 relatively.Thus, by rake 30A, 30B are set, the air-flow that spues from fan 10 can be imported in the outside exhaust outlet 8 smoothly.Thus, can reduce duct resistance, improve the air quantity characteristic of exhaust stream.In addition, can not make main body 50 become big, the space that can effectively apply flexibly chamber interior walls 2 sides of fan 9 forms exhaust channel 30.
And, preferred rake 30A and the rake 30B of forming continuously.Thus, from covering 17 discharge opening 31 exhaust channel 30 to outside exhaust outlet 8, its integral body is towards outside exhaust outlet 8, and the wall of chamber interior walls 2 tilts relatively.Thus, in the importing outside exhaust outlet 8 that the air-flow that spues from fan 10 can be more level and smooth, reduce duct resistance, thereby further improve the air quantity characteristic of exhaust stream.
Upstream side at the sidewall of exhaust channel 30 is formed with rake 30A, is formed with rake 30B in the downstream.Herein, the angle Y of the relative discharge opening 31 of the 30B of preferred angled portion constitutes the angle X with respect to discharge opening 31 greater than rake 30A.That is, the downstream, angle of inclination of the preferred sidewall of the exhaust channel 30 of the discharge opening 31 of exhaust channel 30 relatively is greater than upstream side.In other words, the exhaust channel 30 of upstream side preferably forms in the direction of leaving fan 9, and the angle of the indoor relatively wall of exhaust channel 30 in downstream is preferably little than upstream side.Thus, at upstream side, it is big that the space around the suction inlet of fan 9 becomes, and reduces duct resistance, and simultaneously in the downstream, the depth dimensions of chamber interior walls 2 sides of main body 50 diminishes.That is, realize the raising of scavenging performance and the miniaturization of device.
In addition, the sidewall sections of facing fan 9 sides of exhaust channel 30 is formed by foamed material, prevents and condenses.As shown in Figure 5, in the front of shutter 1, form its central portion shape more outstanding than side portion.By this shape, can guarantee the volume in the space that the front dorsal part by the suction inlet 31B of fan 10 and shutter 1 constitutes.Therefore, can form in the place ahead of the suction inlet 31B of fan 10 and suck the space, guarantee necessary exhaust air quantity.In addition, do not need to reduce exhaust performance, can reduce the thickness of main body 50, the miniaturization of implement device yet.Wherein, the front of shutter 1 can form the crooked comprehensively shape of cross sectional shape that makes the front, and the cross sectional shape of front also can form flat shape by central portion, forms bigger curve form in top or the bottom.
In addition, in outside exhaust outlet 8 sides of cover 17, be preferably formed the inclined plane 17C that tilts to oblique below towards chamber interior walls 2.Thus, form to import the exhaust channel 30 of room air between below inclined plane 17C and shutter 1, play the effect that alleviates aeration resistance.In addition, owing to can demonstrate when being installed in main body 50 on the chamber interior walls 2 very thinly, even when therefore forming bigger curved surface in the bottom of shutter 1, the exhaust channel 30 that forms by inclined plane 17C also can reduce aeration resistance.Therefore, need not reduce exhaust performance, also can be so that main body 50 slimmings.
The back view of the structure of fan was used in the exhaust of supply/discharge type ventilator when Fig. 6 represented present embodiment with fan guard and exhaust.Be provided with the guide part 32 of the profile of the blade 10D that surrounds fan 10 in the inside of cover 17.Guide part 32 forms towards the discharge opening 31 in downstream and with the interval of the profile of blade 10D and becomes big.Guide part 32 can be in its part or all formation in the outside of the profile of blade 10D.By guide part 32 is set like this, can apply flexibly the inner space of cover 17 effectively, can make flowing effectively to discharge opening 31.Improve its exhaust performance thus.
The structure of air feed side then, is described.As shown in figures 1 and 3, at the opposite side of the front of shutter 1 dorsal part, near fan 10, be provided with fan 9 across the air channel spacer portion 19 of distinguishing air feed path 40 and exhaust channel 30.The suction inlet 31A of fan 9 is towards chamber interior walls 2 side settings.The motor 9C of drive fan 9 is arranged on the more front face side of the fan 9 on the shutter 1.Motor 9C is fixed on across the flange portion that forms at its sidepiece and by bolt on the motor fixed head 18 (below, be called fixed head).Fixed head 18 is fixed on the orifice plate 20.Orifice plate 20 has tapered hole part with respect to more close chamber interior walls 2 sides of the suction inlet 31A of fan 9, this tapered hole part have diameter less than the opening diameter of the suction inlet 31A of fan 9, be shaped as the opening that perimembranous is curled in the fan side.Orifice plate 20 is fixed on a plurality of protruding 14A that erects from framework matrix 14 by bolt, from framework matrix 14 fixed intervals is set by protruding 14A and remains on the indoor.Suction side cover (below, be called cover) 21 is mediate in the mode that is clipped between orifice plate 20 and the framework matrix 14.Be positioned on the confession gas stream flow channel of outdoor cold air flow because cover 21, so, in order to prevent to condense, form with the thermal insulation material of foamed material etc.
Near indoors, the dorsal part in shutter 1 front is equipped with the exhaust end cover (below, be called cover) 22 of the opening 22A of part motor 9C, that have the front face side of holding shutter 1 at relative fixed plate 18.Cover 22 be configured to and fixed head 18 between predetermined distance be set, cover fixed head 18 in order to form air feed path 40.
By motor 9C is contained in the opening 22A, the size formation opening 22A with bonding motor 9C and cover 22 prevents that air feed from flowing to adjacent exhaust channel 30 side seepages.Because cover the 22 confession gas stream flow channel that are positioned at outdoor cold air flow, so the thermal insulation material in order to prevent to condense by foamed material etc. forms.
Preferred such cover 21,22 is all formed by the thermal insulation material of foamed material etc.In addition, these inscapes also can be used as a body component and are made of foamed material.In this case, have and cut down parts and the effect by leakage area between the slit in the integrated reduction stream, can realize improving the intensity of the goods of foamed material formation parts.
In addition, the sidewall of fan 10 sides of cover 21 also can constitute, and is provided with to extend with the front dorsal part ways of connecting of shutter 1.In addition, the sidewall of cover 22 fan 10 sides also can constitute, and extends to framework matrix 14 from the front dorsal part of shutter 1 to be provided with.Also can separate air feed path 40 and exhaust channel 30 formations by above-mentioned any structure.By above-mentioned any formation, do not need air channel spacer portion 19, can further shorten the lateral dimension of main body 50, make main body 50 miniaturizations.
