Use Fig. 2 and Fig. 3 below, the structure with the exhaust silencer of the foregoing description explanation is described.
Fig. 2 is the stereogram of exhaust silencer of the present utility model, and Fig. 3 is the profile of same exhaust silencer.
The exhaust silencer 40 of present embodiment is made of the body cover 42 of main body 41 with a flank side surface that covers this main body 41.Suck path 43 in main body 41 1 distolateral formation, and form a plurality of outlet 44A, 44B respectively at the other end of main body 41.Sucking path 43 and each outlet 44A, 44B is communicated with by tributary circuit 45A, 45B.
Suck path 43 and tributary circuit 45A, 45B, constitute with the body cover 42 that covers this ditch by the ditch that is arranged on main body 41 1 flank side surface.This main body 41 forms ditch by cutting, is perhaps carried out integrated molding and is formed ditch by resin.
The upstream-side-end that sucks path 43 inserts, fixing ajutage 4.On a part that sucks path 43, be provided with the quieter material 46 that forms by urethanes.
In the downstream of tributary circuit 45A, be provided with the thin tube part 47A of specific length, the end in the downstream of this thin tube part 47A constitutes outlet 44A.And, being provided with the thin tube part 47B of specific length in the downstream of tributary circuit 45B, the end of downstream side of this thin tube part 47B constitutes outlet 44B.
As shown in the present embodiment, owing to constitute outlet 44A, 44B by thin tube part 47A, 47B, can be easy to discharge dew, also confirm simultaneously the discharge state of gas easily, even thin tube part 47A, 47B are arranged on the mid portion of tributary circuit 45A, 45B, also can realize weakening the pulsation sound that produces by pump.
Tributary circuit 45A and tributary circuit 45B are equal length and same path cross sectional shape.Thin tube part 47A and thin tube part 47B also are equal length and same path cross sectional shape.Like this, owing to be divided into each tributary circuit of many, and the length of the thin tube part that is provided with respectively all is the same with cross sectional shape, and the flow velocity of the gas of being discharged by outlet can be impartial, thereby only can prevent the too fast and flow velocity sound of generation by the flow velocity of an outlet discharge.
The tributary circuit 45B that is connecting outlet 44B is configured in than the lower position of tributary circuit 45A that is connecting outlet 44A.
In the present embodiment, the tributary circuit 45A and the 45B that are divided into two have been described, but under the situation that constitutes the tributary circuit more than three, arbitrary tributary circuit all is configured in the position lower than another one tributary circuit.Like this, because at least one tributary circuit is configured in than on the lower position of another tributary circuit, the tributary circuit that just can be configured in thus on the lower position is derived dew.Have, the length of tributary circuit that is configured in lower position is shorter than other tributary circuits again, and the cross sectional shape that perhaps reduces its path is discharged flow velocity and also is fine to improve it.Owing to so improved the discharge flow velocity of the tributary circuit that is configured on the lower position, just may discharge dew at an easy rate.
Have, the side at the another side of main body 41 is provided with a plurality of claws 48 again.Exhaust silencer 40 is provided with by these claws being inserted in the fin that constitutes heat exchanger 22.
At this, use Fig. 4 and Fig. 5 that diameter and the length of thin tube part 47A and 47B are described.
Fig. 4 is the performance plot of thin tube part optimum diameter of the exhaust silencer of explanation present embodiment, and Fig. 5 is the performance plot of the same thin tube part optimum length of explanation.
At first, when the diameter dimension of thin tube part changes, relation is as shown in Figure 4 arranged between the propagation sound of the flow velocity sound of ventilation and pump.In other words, big if the diameter of thin tube part becomes, the flow velocity sound of ventilation just reduces, but the pulsation sound of pump increases.
Therefore, just determined the diameter of thin tube part at the diameter of pulsation sound in par level of noise scope of ventilation flow velocity sound and pump.Under the situation of present embodiment, the diameter of thin tube part is 2.5mm, preferably determines in the scope of 2~3mm.
Change the propagation sound of the length measurment pump of thin tube part then.As shown in FIG. 5, if prolong the length of thin tube part, the propagation sound of pump just reduces, but when specific length was above, noise almost no longer reduced.Under the situation of present embodiment, be to get final product more than the 10mm as the specific length of thin tube part, adopt 15mm here.
In above-mentioned structure, when drawdown pump 32 runnings, in gas enriching mechanism 31,, supply with the person in charge 34 by oxygen and be inhaled in the drawdown pump 32 by the air behind the oxygen enriching film, be rich in the air of oxygen, deliver in the exhaust silencer 40 by discharging the person in charge 36 and ajutage 4 successively.
Import the air of exhaust silencer 40, in quieter material 46 noise reductions in being inhaled into path 43, reduced flow velocity sound thereby in tributary circuit 45A, 45B, reduce flow velocity.Then, in the middle of thin tube part 47A, 47B, attenuate the pulsation sound that produces by pump 32.So, in exhaust silencer 40, the distinctive pulsation sound of flow velocity sound and vavuum pump can both reduce.
Moreover when control valve 37 during in opening, the circulating resistance by atmosphere ingress pipe 35 is less than the resistance by gas enriching mechanism 31.Therefore, if control valve is in the state of unlatching, atmosphere is not a process gas enriching mechanism of elder generation 31, but preferentially imports on one side from atmosphere ingress pipe 35.Have again, because resistance is little, gas can be than importing more air when the gas enriching mechanism 31, discharging the dew that is detained in the middle of the person in charge's 36 grades, be pushed out easily on one side owing to the raising of wind speed to exhaust silencer 40, also strengthen evaporation capacity because wind speed improves simultaneously, thereby can reduce dew.Have again, just in case dew in path, under the situation of dewfall, under suitable wind speed, also may be pushed out to exhaust silencer 40 with freezing.
Under the state that control valve 37 is opened,, thereby can reduce like this owing to wind speed improves the flow velocity sound that produces owing to tributary circuit 45A, 45B at exhaust silencer 40 reduce flow velocity.
The control operation of the control device 38 shown in the following describes in the above-described embodiments.
At first explanation is only by the situation of controlling drawdown pump 32 and control valve 37 from the input signal of air velocity transducer 39A.
Detecting wind speed when setting value is above, be judged as normal condition, control valve 37 is closed, and makes drawdown pump 32 work.Wind speed is when setting value is following then, and drawdown pump 32 remains in operation, and control valve 37 is opened.If make under the situation of ventilation channel obturation by dew etc., discharge by control valve and import extraneous gas, can increase in the ventilation channel wind speed and with dew by outlet 33 discharges.But under situation about not reverting to through the time wind speed of setting under this state more than the setting value, drawdown pump 32 just stops operating.
The following describes by the situation of controlling drawdown pump 32 and control valve 37 from the input signal of air velocity transducer 39A and temperature sensor 39B.
Detecting wind speed and extraneous gas temperature under the situation more than the setting value, be judged as normal condition, control valve 37 closures make pressure-reducing valve 32 work.Externally temperature is under the situation below the setting value, because dew might freeze, control valve 37 is opened the wind speed that makes in the ventilation channel to be increased, and tries hard to prevent to freeze.Externally temperature is higher than setting value, but wind speed is lower than under the situation of setting value, and pressure-reducing valve 32 remains in operation control valve 37 is opened.If because dew etc. make under the situation of ventilation channel obturation, discharged and the importing extraneous gas by control valve 37, the wind speed in the ventilation channel increases, and dew can be discharged by outlet 33.But be not returned to setting value when above through the time wind speed of setting under this state, perhaps externally temperature is reduced under the following situation of setting value, and drawdown pump 32 just stops action.
Have again, shown in the present embodiment, in atmosphere ingress pipe 35, pressure reducer is set, thus, reduce to have effect on the sound method at change pressure.This pressure reducer makes resistance that air passes through less than gas enriching mechanism 31.
Based on operation control valve off and on such as the irrelevant setting-up time of atmospheric temperature, thus, can carry out importing fresh atmosphere indoor and carrying rich oxygen containing air with switching,, also can make it to have the function of accurate ventilation though do not expect essence ventilation effect resemble the ventilation fan.
Such as, as under the situation of operation test running button or under the situation of the affirmation button on operating and remote controlling or the main body, also can import extraneous gas from the extraneous gas ingress pipe by the signal of opening controlling valve.
In the present embodiment, shown running of control drawdown pump or situation about stopping, but also can turn round by force or ability control such as weak running.Such as, under the situation that wind speed reduces, make the strong running of operating as of drawdown pump, also can make the running with the drawdown pump of the breakdown action interlock of control valve become strong running.
In the present embodiment, illustrated that the selective gas enriching devices is applicable to the situation of the split-type air conditioner device that uses in the air conditioning of living space, but in such as air conditioner for vehicles, integral air conditioner device, also can use, also be applicable to other air cleaner or medical oxygen enriching devices, portable oxygen enriching device, burner with the nitrogen enriching devices of oxygen enriching devices, use in freezer etc. is fresh-keeping etc.
In the present embodiment, the application of the gas enriching mechanism that uses the oxygen enriching film has been described, can have realized the oxygen enriching function but also can have, in the case as hollow fiber membrane etc., use force (forcing) pump to replace drawdown pump, perhaps also air-supply arrangement can be used as pump.
