To achieve these goals, the chain induction device that the utility model proposes, comprise induction air channel, for the main opening of First air, for absorbing the return air inlet of room air, First air is mixed the nozzle of all pressing with room air and by mixed air transmission to indoor air outlet, it is inner that described nozzle is located at induction air channel, described return air inlet is opened in the both sides up and down of nozzle, the direction of motion of described First air and the direction of motion of room air perpendicular, described nozzle comprises primary nozzle and secondary nozzle, described return air inlet is opened in the both sides up and down of primary nozzle and secondary nozzle respectively, the injection direction of described primary nozzle and secondary nozzle all overlaps with the direction of motion of First air, described primary nozzle and secondary nozzle are respectively equipped with a plenum chamber and second static pressures case, the inside in induction air channel is all located at by a described plenum chamber and second static pressures case, a described plenum chamber is fixedly connected with primary nozzle, described second static pressures case is fixedly connected with secondary nozzle, described First air is respectively through a plenum chamber, primary nozzle, second static pressures case and secondary nozzle.
Further, described return air inlet is also provided with return air filter, described return air filter is fixedly connected with the return air inlet of upside.
Further, between described plenum chamber and the inwall of second static pressures case and induction airduct, be equipped with rubber cushion, a described plenum chamber is fixedly connected with induction airduct by screw with second static pressures case.
Further, a described plenum chamber and primary nozzle, by being welded to connect, are also filled with encapsulant in the junction of described plenum chamber and primary nozzle.
Further, described second static pressures case and secondary nozzle, also by being welded to connect, are also filled with encapsulant in the junction of described second static pressures case and secondary nozzle.
The beneficial effects of the utility model: the utility model can realize the supply air temperature difference after twice induction and decrease than an induced draught temperature difference, and comfort improves.And chain induction device mixes room air twice, air output adds, and improves the rate of ventilation in room.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the floor map of the utility model chain induction device;
Fig. 2 is the schematic diagram of all air inducer system in prior art;
In figure, 1-primary nozzle, 2-bis-nozzles, 3-plenum chamber, 4-return air filter, 5-return air inlet, 6-second static pressures case, 7-air outlet.
[detailed description of the invention]
Consult Fig. 1, chain induction device, comprise induction air channel, for First air main opening, for absorb room air return air inlet 5, First air mix the nozzle of all pressing with room air and by the air outlet 7 of mixed air transmission extremely indoor, it is inner that nozzle is located at induction air channel, return air inlet 5 is opened in the both sides up and down of nozzle, the direction of motion of First air and the direction of motion of room air perpendicular.Wherein, nozzle comprises primary nozzle 1 and secondary nozzle 2, return air inlet is opened in the both sides up and down of primary nozzle 1 and secondary nozzle 2 respectively, the injection direction of primary nozzle 1 and secondary nozzle 2 all overlaps with the direction of motion of First air, primary nozzle 1 and secondary nozzle are respectively equipped with a plenum chamber 3 and second static pressures case 6, the inside in induction air channel is all located at by a plenum chamber 3 and second static pressures case 6, one time plenum chamber 3 is fixedly connected with primary nozzle 1, second static pressures case 6 is fixedly connected with secondary nozzle 2, First air is respectively through a plenum chamber 3, primary nozzle 1, second static pressures case 6 and secondary nozzle 2.
Wherein, air outlet 7 adopts diffuser feeding, and mixed air-flow is more releived, and improves the comfort level of user.
Particularly, return air inlet 5 is also provided with return air filter 4, return air filter is fixedly connected with the return air inlet 5 of upside, makes mixed air more clean, improves the quality of room air.
Further, rubber cushion is equipped with between a plenum chamber 3 and the inwall of second static pressures case 6 and induction airduct, improve sealing and the stability of induction airduct, make the vibrations that produce when persuader works and sound less, plenum chamber 3 is fixedly connected with inducing airduct by screw with second static pressures case 6.
Wherein, a plenum chamber 3 and primary nozzle 1, by being welded to connect, are also filled with encapsulant at a plenum chamber 3 with the junction of primary nozzle 1.First air blast after a plenum chamber 3 is converted into static pressure, then sprayed by primary nozzle 1, form the air-flow that pressure is larger, can not only to producing larger suction function, more room air is made to enter induction airduct by return air inlet 5, but also First air speed of moving in induction airduct can be accelerated, improve the operating efficiency of persuader.
Accordingly, second static pressures case 6 and secondary nozzle 2, also by being welded to connect, are also filled with encapsulant at second static pressures case 6 and the junction of secondary nozzle 2.That is, through second static pressures case 6 after the First air of primary nozzle 1 mixed with room air first time, now blast is converted into static pressure again, and then is sprayed by secondary nozzle 2, form the larger air-flow of pressure again, with absorption and carry out room air and carry out second time and mix.
Specific works process of the present utility model is as follows: after First air enters a plenum chamber 3, blast is converted into static pressure, primary nozzle 1 subsequently by being attached thereto is ejected, now induce in airduct and produce negative pressure, induction room air enters induction airduct by return air inlet 5 and mixes with First air first time; Then, pass through the mixed airflow of first time mixing through second static pressures case 6 and secondary nozzle 2, repeat the change procedure of static pressure to high pressure again, now room air is induced to again induction airduct inside, and carry out second time with mixed airflow and mix, finally, the high velocity air through secondary mixing is sent into indoor by the air diffuser of air outlet 7.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
