no. 1 approach

[0028] figure 1 It is a block diagram of the oxygen supply device 1 according to one embodiment (first embodiment) of the present disclosure. The oxygen supply device 1 is a device that generates and supplies oxygen at a concentration higher than that in the air, and is used, for example, for home oxygen therapy to provide high-concentration oxygen to patients with respiratory diseases or the like. The oxygen supply device 1 includes a plurality (two in the present embodiment) of oxygen concentrators A and B and one control unit C that generate high-concentration oxygen, respectively.

[0029] The structure of the oxygen concentrator A is the same as that of the oxygen concentrator B. Therefore, the same elements and configurations will be described with the same reference numerals attached thereto.

[0030] The oxygen concentrator A and the oxygen concentrator B respectively include: a compressor 2, which compresses the air sucked from the outside; a first adsorption cylind...

[0047] Figure 5 It is a block diagram showing the oxygen supply device 1 according to the second embodiment of the present disclosure. and figure 1 The difference between the illustrated embodiments is that, in this embodiment, the oxygen tank 4, pressure reducing valve 9, and flow control valve 10 disposed downstream of the product valve 8 are shared by the two oxygen concentrators A1, B1. . Therefore, elements and structures common to both embodiments are assigned the same reference numerals, and descriptions of these elements and structures are omitted for brevity.

[0048] In this embodiment, in addition to the shared control unit C, the oxygen tank 4 and the like are also shared. figure 1 Compared with the first embodiment shown, the overall structure of the device can be further simplified, thereby achieving cost reduction. Similar to the first embodiment, in this embodiment as well, the peak and fluctuation of the power consumption of the oxygen supply device 1 can...

Abstract

An oxygen supply apparatus 1 produces and supplies oxygen at a higher concentration than the oxygen concentration in air. Each oxygen supply apparatus comprises a plurality of oxygen concentration units A and B, which generate oxygen at a high concentration, and one control unit C, which controls operation of the plurality of oxygen concentration units. The control unit C is configured so that when an existing oxygen concentration unit is removed and a new oxygen concentration unit is added, the oxygen concentration units A and B provided in the oxygen supply apparatus 1 can be operated following the removal or addition.

Description

technical field [0001] The present disclosure relates to an oxygen supply device. More specifically, it relates to an oxygen supply device that generates and supplies oxygen with a concentration higher than that in air. Background technique [0002] Various oxygen supply devices are known that generate oxygen at a concentration higher than that in air and supply the oxygen to users. These devices are used to improve the living environment by increasing the oxygen concentration in the living room, in addition to home oxygen therapy for patients with, for example, lung diseases where the lung function is low. [0003] In recent years, these oxygen supply devices have been required to increase in size and capacity. Regarding the demand for a larger capacity, there is the following problem: Although it is conceivable to increase the size of the pump and the adsorption tube constituting the device to expand the overall device, in order to develop a large pump and adsorption tub...
