As shown in Figure 1, air purifier of the present invention is a divergence type, forms for the oxygen generator of a certain amount of oxygen of indoor supply jointly by the air cleaning unit that keeps room air uniform temperature and humidity with this device.

Air purifier is mainly formed by there being the cohesion compression to cool off the off-premises station (10) of medium and the cooling medium of vapor-compression and the indoor set (20) that room air carries out heat exchange, and cooling medium pipes (30) connect off-premises station (10) and indoor set (20) is carried the cooling medium.

Off-premises station (10) comprise cohesion cooling medium cohesion compressor (11), carry the fan (12) of air and compressor (13) that compression cooling medium are delivered to cohesion compressor (11) etc. to cohesion compressor (11).Indoor set (20) comprise to the evaporation of HTHP cooling medium and the evaporimeter (21) that expands, the air of heat exchange in evaporimeter (21) deliver to indoor fan (22), at the inlet hole (23) of indoor set (20) the shell formation of adjacency evaporimeter (21) and fan (22) and tap (24) etc.

And the off-premises station (10) in the air purifier structure of the invention described above is identical with general air purifier with indoor set (20), so do not describe in detail.Describe oxygen generator below in detail.

Oxygen generator is made up of the oxygen conveying pipe (300) of the oxygen generator (100) that is located at off-premises station (10) optional position, the oxygen escaper (200) that is located at indoor set (20), connection oxygen generator (100) and oxygen escaper (200).

Air purifier of the present invention, as shown in Figure 1, oxygen generator (100) and oxygen escaper (200) are located at respectively on off-premises station (10) and the indoor set (20), for the running that connects together of more oxygen and off-premises station (10) and indoor set (20) is provided.Therefore, oxygen generator is than the easier installation of general air purifier, because oxygen generator (100) is located at the outside, in the noise inlet chamber in the time of can preventing oxygen generator (100) running.To be located at indoor situation separately different with general oxygen generator, and in the present invention, oxygen generator and air purifier are integrated, make oxygen generator not influence the interior space.Oxygen generator (100) should be located at the top of off-premises station (10), and like this than being installed in the side, it is not only convenient and safer to install.Therefore, oxygen generator (100) though can be installed in any position of off-premises station (10) except inlet hole,, still as shown in Figure 1, be advisable in the top that should be located at off-premises station (10).

In the total of oxygen generator of the present invention, oxygen generator (100) independent operation in air purifier of the present invention Figure 2 shows that the general structure of this oxygen generator.

As shown in Figure 2, oxygen generator (100) is made up of a plurality of key elements, and it comprises Machinery Ministry (120) with the function of producing oxygen and the shell (110) of protecting Machinery Ministry (120).

Machinery Ministry (120) generally will separate in the atmosphere 21% oxygen and supply with the user.The oxygen producing method of Machinery Ministry (120) can adopt the Hydrolyze method of the electricity of commonly using or the mode of chemical reaction, has occurred utilizing the method for the direct adsorption of oxygen of adsorbent recently.Adopt the adsorbent mode that is simple and easy to usefulness, safety in the present invention, therefore, shown in Figure 2 is the structural representation that utilizes the oxygen generator of adsorbent mode.

Machinery Ministry (120) is the air pump (121) by circulating air; Be connected side by side with air pump (121), and first, second transfer valve of selection connection air duct (122a, 122b); (122a 122b) is connected, and the adsorption tower (123) of absorption nitrogen adsorption agent from air is filled by portion within it with first, second transfer valve; The detection valve (124) that is located on the oxygen conveying pipe is formed.

Between air pump (121), first transfer valve (122a) and adsorption tower (123), link to each other, between air pump (121), second transfer valve (122b) and adsorption tower (123), link to each other by second carrier pipe (125b) by first carrier pipe (125a).First, second air delivery pipe (126a, 126b) and first, second transfer valve (122a 122b) links to each other and to communicate with the external world.Therefore, (126a 126b) is drawn in the oxygen generator (100) Wai Jie air by first, second air delivery pipe.

Because (126a, 126b) function is identical, and is convenient for design and installation, adopts a merging pipe to be advisable for first, second air delivery pipe.Adsorption tower (123) is filled the strong zeolite of adsorption of nitrogen airway dysfunction for well, preferably adds a spot of suction and prevents the water absorbing agent that adsorption function is low.

For the safe handling that makes oxygen generator (100) with keep certain oxygen and produce, need provide the air of certain high temperature low humidity.

According to seasonal variations, in summer, if malaria is inhaled in the oxygen generator (100), though added a spot of water absorbing agent in adsorption tower (123), adsorbable dose is exposed in the air that contains excess moisture.Reduce the affinity and the oxygen generation function of the nitrogen of adsorbent like this.Simultaneously, the moisture that can not fully discharge suction also shortens the life-span of adsorbent.In winter, if oxygen generator (100) has sucked the air of low temperature, though because the compression of air pump (121) can promote certain temperature,, the air that remains relative low temperature that adsorption tower (123) sucks.Cryogenic air also reduces the function of oxygen generator (100) like this, can not produce the oxygen of high concentration.

Owing to these reasons, in order to improve the performance of oxygen generator (100), as shown in Figure 2, and should be in air suction place of oxygen generator (100), promptly (126a 126b) is provided with the heater of certain form to first, second air delivery pipe.

As shown in Figure 3, this heater can adopt and be located at first, second air delivery pipe (126a, 126b) Nei mesh heater (mesh type heater) (131), this mesh heater (131) should heat outside air not influencing under the condition that air flows.

Heater also can adopt thermal wire (132), because do not influence flowing of air, therefore, can be located at first, second air delivery pipe (126a, inside 126b) or and outside.

If heater (131,132) is set, (126a 126b) more should adopt perforated pipe (133) to first, second air delivery pipe.(moving air discharges and sucks repeatedly for 126a, 126b) interior flowing at first, second air delivery pipe by perforated pipe (133) by the air of heater (131,132) heating.That is, heated air discharges, and can improve the temperature of surrounding air part, and these ambient airs are drawn into first, second air delivery pipe again, and (126a flows in 126b), mixes and be heated.Therefore, improve the thermal effect that adds of outside air by the heat exchange of perforated pipe (133).

Oxygen conveying pipe in the oxygen generator (300) is transported to oxygen escaper (200) to the oxygen that oxygen generator (100) produces.Arrange in the cooling media pipe, as shown in Figure 1, the pipeline of the low-temp low-pressure cooling medium that flow is located at the place of more approaching oxygen conveying pipe than mobile HTHP cooling media pipe, can reduce the temperature of oxygen like this, fresh comfortable oxygen is provided.In order more effectively to reduce the temperature of oxygen, oxygen conveying pipe (300) can be twined the pipeline of low-temp low-pressure cooling medium.

Oxygen escaper (200) in the oxygen generator links to each other with oxygen conveying pipe (300), plays that oxygen is discharged to indoor effect.The rear that oxygen escaper (200) can be located at the place ahead that will cool off the evaporimeter (21) that sucks air or cool off the evaporimeter (21) of air discharge.Therefore, oxygen escaper (200) can provide the oxygen of cool fresh.

In sum, this invention air purifier has the structure that provides oxygen for indoor.According to these structures, illustrate that with reference to Fig. 1 operation process of the present invention is as follows.

Operation process of the present invention roughly is divided into the air cleaning process of keeping indoor uniform temperature and humidity and is the indoor oxygen supply process that a certain amount of oxygen is provided.The air cleaning process is to be finished by off-premises station (10) and indoor set (20), and oxygen supply process is to be finished by oxygen generator (100) and oxygen escaper (200).

In the air cleaning process, the low-temp low-pressure cooling medium that compressor (13) compression is transported to from evaporimeter (21) by cooling medium pipes (30).Compressed cooling medium become HTHP liquid phase cooling medium in condensed device (11), and are transported to evaporimeter (21) by cooling medium pipes (30).Expand at evaporimeter (21), the cooling medium of evaporation with carry out heat exchange and become the cooling air from suction inlet (23) inhaled air.The air of this cooling is delivered to indoor through outlet (24), the indoor cooling air that provides is provided.

Air cleaning process of the present invention is identical with general clarifier, therefore no longer describes in detail.Describe oxygen in detail below with reference to Fig. 1 and Fig. 2 and supply with process.

Oxygen is supplied with process and can be subdivided in the oxygenous process of oxygen generator (100), the oxygen that produces is delivered to the oxygen course of conveying of oxygen escaper (200) and the process of being discharged oxygen by oxygen escaper (200) by oxygen conveying pipe (300).

Oxygenous process can be divided into from outside air absorption nitrogen oxygen separation to be delivered to the pressure process of adsorption tower (123) and discharges the vacuum process that is adsorbed on the nitrogen on the adsorbent.

In pressure process, by the driving of air pump (121), through first, second transfer valve (122a, 122b) suction and compression outside air.Compressed air is delivered in the adsorption tower (123) through second transfer valve (122b) and second carrier pipe (125b), and the outside air that adsorption tower (123) is entered pressurizes.

In pressure process, the nitrogen in the outside air is adsorbed the adsorbents adsorb in the tower (123), oxygen separation simultaneously, when reaching certain pressure after testing valve (124) be discharged to oxygen conveying pipe (300).

Outside air can pass through the air that heater (131,132) becomes the high temperature low humidity, and (126a 126b) delivers in the adsorption tower (123) by first, second air delivery pipe.Therefore, the present invention no matter how the state of outside air can produce the oxygen of a certain amount of high concentration, uses anti-blushing agent can prolong the life-span of adsorbent in pressure process simultaneously.

In vacuum process, (122a, direction 122b) and pressure process are antithesis for first, second transfer valve.That is, first transfer valve (122a) links to each other with first carrier pipe (125a), and second transfer valve (122b) links to each other with second carrier pipe (125b).The effect of air pump (121) is identical with pressure process, delivers to second carrier pipe (125b) from first transfer valve (122a), leans on the attraction of air pump (121) to form vacuum state in adsorption tower (123).In vacuum process, nitrogen comes off from adsorbent, discharges through first carrier pipe (125a), first transfer valve (122a), air pump (121), second transfer valve (122b), second air delivery pipe (126b) from adsorption tower (123).Like this, the pressurized process of adsorbent in the adsorption tower (123) is reduced into oxygenous state again.

The production process of oxygen is exactly constantly to produce oxygen in repeatedly pressurization and vacuum process.

In the course of conveying of oxygen, the oxygen that is produced is delivered to oxygen escaper (200) through oxygen conveying pipe (300), and the air that final oxygen is cooled off by the air cleaning process in the discharge process of oxygen is discharged to indoor by indoor set (20) together.

The above, it only is several preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
