Embodiment 1

[0029] Use below Figure 1 to Figure 5 One example of the oxygen concentrator of the present invention will be described. figure 1 It is a front view of an embodiment of the oxygen concentrator of the present invention. figure 2 It is a plan view of the inside of the oxygen enricher. image 3 It is the inside right side view of the oxygen enricher. Figure 4 It is the inside left side view of the oxygen enricher. Figure 5 It is a circuit diagram explaining the outline of the gas flow.

[0030] In addition, piping is overlapped in the drawing and is difficult to understand, so a part of the piping is cut out or bent in the illustration. image 3 Indicates the state where the right side wall of the compressor cover is removed. again, Figure 5 In the circuit diagram of , the arrangement positions of parts are changed appropriately. For example, the air filter is described on the right, but actually changed from figure 2 , image 3 and Figure 4 It can be seen that i...

Abstract

The invention provides an oxygen concentration device capable of preventing dew condensation as possible. The technical scheme of the invention is that the dry air with moisture removed using a moisture removal hollow fiber membrane device (24) is supplied from a dry air discharge port (24d) of the moisture removal hollow fiber membrane device to an oxygen concentrating hollow fiber membrane device (11). Thus, the water content of the concentrated oxygen generated by the oxygen concentrating hollow fiber membrane device can be reduced. Then, the dried concentrated oxygen from the oxygen concentrating hollow fiber membrane device is introduced to a concentrated nitrogen intake port (24a) of the moisture removal hollow fiber membrane device, mixed with the removed moisture in the moisture removal hollow fiber membrane device, and discharged from a moisture discharge port (24b) of the moisture removal hollow fiber membrane device after the concentration of the removed moisture is reduced.

Description

technical field [0001] The present invention relates to an oxygen concentrator for supplying concentrated oxygen to people studying and improving the efficiency of reading and studying. Background technique [0002] Conventionally, as a device for supplying high-oxygen-concentration gas, for example, as described in JP-A-2005-16867 (Patent Document 1), it is known that a device for blowing high-oxygen-concentration gas is installed on a table. This high-oxygen-concentration gas supply device is provided with a high-oxygen-concentration gas generator outdoors, which is large in size and troublesome to move and construct. [0003] Therefore, as described in Japanese Patent Laid-Open No. 2015-230774 (Patent Document 2), for example, a compact oxygen concentrator that can be easily installed on a desk or the like has been studied. [0004] However, the oxygen concentrator of Patent Document 2 is incorporated in a lighting desk lamp, and the oxygen concentrator cannot be install...
