That is, between above-mentioned nitrogen adsorption device 80 and the oxygen excavationg pump 90 non-return valve 100 is installed, it can only the direction from above-mentioned nitrogen adsorption device 80 to oxygen excavationg pump 90 be flowed.Be equipped with the 1st between above-mentioned nitrogen adsorption device 80 and the air suction inlet 72 and open and close valve 102, thereby limit flowing between above-mentioned nitrogen adsorption device 80 and the air suction inlet 72; Then be equipped with the 2nd between above-mentioned nitrogen adsorption device 80 and the nitrogen excavationg pump 92 and open and close valve 104, thereby limit flowing between above-mentioned nitrogen adsorption device 80 and the nitrogen excavationg pump 92.
The following describes the operation principle of the detachable air conditioner among the present invention of as above structure.
At first, when above-mentioned detachable air conditioner is received power supply, in indoor set 50, room air is drawn in the suction inlet 52 by sucking grid 58, and carry out heat exchange with refrigerant, the air of heat exchange is discharged to the direction of indoor appointment by the discharge grid 58 of outlet 54, thereby freezes or make warm operation indoor.
Wherein, above-mentioned refrigerant is sent in the off-premises station 62 by coolant piping 60, after refrigerant that flows into by above-mentioned coolant piping 60 and outdoor air carry out heat exchange, turns back in the above-mentioned indoor set 50 again.
Simultaneously, in the side of above-mentioned indoor set 50, but according to the above-mentioned oxygen generating unit 64 of user's needs installation or removal.
As shown in Figure 3, in being installed on the oxygen generating unit 64 of indoor set 50, oxygen excavationg pump 90 is started working, and the air suction inlet 72 that passes through shell 70 sucks room airs, be drawn into the room air in the above-mentioned air suction inlet 72, after filtering in air filter 96, flow in the above-mentioned nitrogen adsorption device 80, the nitrogen in the room air is then by above-mentioned nitrogen adsorption device 80 absorption and removal.
At this moment, the 1st switching valve 102 is an open state, and the 2nd switching valve 104 is a closed condition.
Thus, effect by nitrogen adsorption device 80, nitrogen in the room air will be adsorbed removal, and generate oxygen simultaneously, above-mentioned oxygen is under the swabbing action of oxygen excavationg pump 90, by the nozzle 90a of above-mentioned oxygen excavationg pump 90, be ejected into the oxygen outlet 74 of above-mentioned shell 70, thereby supply to indoor.
As mentioned above, above-mentioned oxygen generating unit 64 sucks room airs, and generate directly be discharged to behind the oxygen indoor, thereby the oxygen content in the room air is improved rapidly, thereby comfortable environment in the holding chamber.Simultaneously, owing to directly discharge by said nozzle 90a, thereby the discharge rate of increase oxygen.
Particularly, when being connected with oxygen cover (air mask) on the nozzle 90a of above-mentioned oxygen excavationg pump 90, can concentrate to suck the oxygen that generates in the above-mentioned oxygen generating unit, thereby reach the effect of motion back fatigue recovery, also without benefits to examinee or old man, patient simultaneously.
On the contrary, when above-mentioned oxygen generating unit 64 was worked a period of time, accumulating in the zeolite 82 of above-mentioned nitrogen adsorption device 80 had nitrogen, thereby reduces the absorption property of above-mentioned nitrogen adsorption device 80.By discharge the nitrogen in the above-mentioned nitrogen adsorption device 80 to the outside, make above-mentioned zeolite 82 can carry out adsorption operations again.
Promptly, as shown in Figure 4, opening and closing valve 102 the above-mentioned the 1st closes, the above-mentioned the 2nd opens and closes under valve 104 opened state, when nitrogen excavationg pump 92 drove, the inside of above-mentioned nitrogen adsorption device 80 became vacuum state, and the above-mentioned nitrogen that accumulates is broken away from, the nitrogen that breaks away under the swabbing action by above-mentioned nitrogen excavationg pump 92 will be along nitrogen drain hose 94 to outdoor discharge.
After above-mentioned nitrogen discharging operation carried out the sufficient time, above-mentioned nitrogen excavationg pump 92 stopped to drive.Simultaneously, above-mentioned oxygen excavationg pump 92 drives again.At this moment, the above-mentioned the 1st opens and closes valve 102 opens, and the above-mentioned the 2nd opens and closes 104 on valve closes.
Above with reference to description of drawings the detachable air conditioner among the present invention.But the present invention is not confined to the foregoing description and accompanying drawing, and in the scope that does not exceed the technology of the present invention thought, the operator of relevant industries can carry out various deformation to it.
That is, the above-mentioned oxygen generating unit 64 dismantled and assembled two sides that are installed on indoor set 50 also can be installed on upper and lower and front and rear.Above-mentioned shell 70 can have multiple shape according to the kind of each indoor set 50, and its internal structure also has various ways according to design condition.
In addition, be installed on the method for indoor set 50 as above-mentioned oxygen generating unit 64, be connected and fixed by connecting elements, or on the side of above-mentioned indoor set 50 and oxygen generating unit 64, correspondence is formed with the assembly structure of grab or slip shape, thereby carries out mount.
