[Prior art] In recent years, many patients are suffering from respiratory system diseases such as asthma, emphysema, and chronic bronchitis, and one of the most effective treatments for these diseases is
One method is oxygen inhalation. In such oxygen inhalation methods, oxygen concentrators that separate and concentrate atmospheric oxygen in the immediate vicinity of the patient are attracting attention as a simple oxygen supply source. This type of oxygen concentrator uses an adsorption separation method using an adsorbent such as zeolite that more selectively adsorbs oxygen or nitrogen, and a selective permeation membrane that allows oxygen to permeate at a higher rate than nitrogen. There are two types of membrane separation methods.

The structure is such that a predetermined oxygen concentration is obtained by maintaining a vacuum state of rr.

In order to continuously obtain air enriched with oxygen components, the adsorption separation method requires air to be adsorbed and desorbed by an adsorbent, so the operating pressure is a so-called pressure swing method in which pressurization and/or depressurization are repeated. The compressor makes a lot of noise, and the noise repeatedly increases and decreases, causing pain to users, especially sick people. In the membrane separation method, the generated oxygen-enriched air is simply taken out under vacuum, and the pressure (degree of vacuum) is also constant, so compared to the adsorption separation method, the noise generated by the vacuum pump is considerably lower. In addition, when the surrounding noise level is low at night, it can be painful for the patient or the people in the flower shop in the vicinity, especially when sleeping.

In an oxygen concentrator, the pump means is driven by the power of the electric motor, so the electric motor is cooled and the gas is compressed (in the adsorption separation method, air is produced, and in the membrane separation method, oxygen-enriched air is produced from vacuum to atmospheric pressure). An essential requirement for stable and efficient operation of an oxygen concentrator is to prevent as much as possible the temperature rise of the pump itself that occurs due to the compression of the oxygen concentrator. Therefore,
In general, a method is adopted in which air with a concentration several to several ten times as concentrated as oxygen-enriched air is brought into contact with the electric motor and pump via a cooling fan to cool them. For this reason, the oxygen concentrator is provided with a large opening on its outer wall for air to flow in and out, and a flow path with a large space inside, as a passage for cooling air.

一方酸素濃縮器における騒音の発生源はポンプ。On the other hand, the source of noise in oxygen concentrators is the pump.

Electric motors and cooling fans are the main components, and in the adsorption separation method, when the adsorbent is regenerated by pressure swing, the nitrogen-rich air adsorbed by the adsorbent is depressurized as exhaust air and released to the atmosphere. Although the exhaust noise is instantaneous, it is relatively loud.

The easiest and surest way to keep noise levels low is to install the noise source in a closed space, but as is clear from the above explanation, it is best to install air passages to cool each part. Due to the need to ensure security, it was difficult to adopt the above measures, and an effective solution was desired.

In particular, adsorption-type oxygen concentrators, which are currently used as medical oxygen sources, have a large oxygen production capacity that shows an oxygen concentration of approximately 90% at a flow rate of 2 fL/min. The noise level is as high as approximately 50 to 55 dB (A) (at a distance of 1 m), and unless soundproofing measures are taken, such as placing it far away from the patient's room, the patient's sleep will be disturbed. Improvements are expected. It had been.

For example, in conventional adsorption oxygen concentrators, there is usually a temperature difference between the outside air and the exhaust air, and the temperature of the exhaust air is 10 degrees Celsius higher than the outside air.
Even if the soundproofing effect can be obtained by simply covering the entire concentrator, if the outside air and exhaust air mix, the temperature inside the cabinet will rise and have a negative impact on the concentrator. Become. In order to prevent this, a sound-absorbing box with separate passages for outside air intake and exhaust is installed with the cabinet and oxygen concentrator of the present invention, with a partition having an insulating effect so that outside air and exhaust air do not mix. The device has.

Roughly speaking, in the oxygen concentrator of the present invention, in order to prevent the temperature of the oxygen concentrator body from rising, the silencing box is placed near the exhaust outlet provided in the concentrator, so that the heated exhaust gas is not heated again. Avoid contact with the soundproofing concentrator as much as possible, and provide a space in between so that the outer surface of the concentrator other than the surface that comes into contact with the soundproofing box does not come into contact with the inner surface of the soundproofing wall that constitutes the cabinet. It is desirable to cool the entire concentrator by circulating the air (ie, outside air) taken in from an air intake port provided in the wall into the space.

Further, the sound deadening box of the present invention has separate passages for atmospheric air taken in from an air intake port provided in the soundproof wall, and a passage for exhaust air led out from an exhaust outlet provided in the concentrator. As mentioned above, it prevents noise propagation while maintaining a ventilation structure instead of a closed structure.
It muffles the sound. In particular, the structure of the sound deadening box includes installing a baffle plate in each passage, installing a sound absorbing material or a sound deadening material such as a lead plate or a sponge-like member on the inner wall surface, and installing the entrance of the exhaust passage. It is desirable to install a sound absorbing part facing the exhaust outlet of the storage box in order to achieve a sound deadening or soundproofing effect. Note that the sound deadening box may be located anywhere within the cabinet (the atmospheric passage and the exhaust passage may be installed separately).
