  The present invention relates to an oxygen enricher that provides oxygen enriched air.

The conventional oxygen enricher has a basic structure consisting of a device main body that generates oxygen-enriched air by concentrating oxygen in the air, and an oxygen discharge port that discharges oxygen-enriched air connected to this device, with additional functions. For example, it has been developed in various ways, for example, having negative ion generation means (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 10-234836

  Conventional oxygen enrichers require high functionality, as represented by oxygen enrichers with negative ion generation function, and only the effects and effects such as relaxation by suction of high-concentration oxygen air For the former request, a complicated control means such as a microcomputer is provided to satisfy the customer even if the product price is somewhat high, but for the latter request, for example, start and stop of operation There is a desire to make it as cheap as possible if it has only the functions. However, even in the latter case, it is necessary to be able to freely set the operation time of the main body, but it is necessary to provide a timer circuit using a microcomputer and the timer itself, and it can not reduce the manufacturing cost There was a problem.

  The present invention solves the above-described conventional problems, and an object thereof is to provide an inexpensive oxygen enricher that is easily available to the user.

  In order to solve the conventional problem, an oxygen enricher of the present invention includes a suction means for sucking air through oxygen enrichment means to generate oxygen-enriched air, an energization means for energizing the suction means, Temperature detecting means for detecting a temperature rising with the operation of the suction means, and when the temperature detected by the temperature detecting means reaches a predetermined set operating temperature, the energization to the suction means by the energizing means is stopped. And the positional relationship between the temperature detection means and the suction means can be changed. For example, when the distance between the temperature detection means and the suction means is increased, the temperature detected by the temperature detection means The time until the temperature reaches a predetermined operating temperature can be extended, that is, the operation time of the main body can be lengthened. Conversely, if the distance between the temperature detection means and the suction means is reduced, the temperature detection means Since the time until the known temperature reaches the preset operating temperature can be shortened, that is, the operation time of the main body can be shortened, the operation time can be set even without expensive timer means, and the overall configuration of the product Therefore, it is possible to provide an oxygen enricher that is easily available to the user.

  The oxygen enricher of the present invention includes a suction means for sucking air through the oxygen enrichment means to generate oxygen enriched air, an energization means for energizing the suction means, and an increase in operation of the suction means. Temperature detecting means for detecting the temperature to be performed, cooling means for cooling the suction means, and cooling capacity variable means capable of changing the cooling capacity by the cooling means, and the temperature detected by the temperature detecting means is predetermined. When the set operating temperature is reached, the energization of the suction means by the energization means is stopped. For example, when the cooling capacity of the cooling means is increased by the cooling capacity variable means, the temperature rise rate of the suction means becomes slow. The time until the temperature detected by the temperature detecting means reaches a predetermined set operating temperature can be extended, that is, the operation time of the main body can be lengthened. If the cooling capacity is reduced, the temperature rise speed of the suction means is increased, and the time detected by the temperature detection means reaches a predetermined set operating temperature, that is, the operation time of the main body can be shortened. Even if there is no expensive timer means, it is possible to set the operation time, simplifying the overall configuration of the product and reducing the cost. In addition, a small and low-priced pump with a maximum capacity can be used in the maximum load state, so that the price can be reduced.

  The oxygen enricher of the present invention simplifies the overall configuration of the product and can be provided at low cost.

  According to a first aspect of the present invention, there is provided: a suction unit that sucks air through the oxygen enrichment unit to generate oxygen enriched air; an energization unit that energizes the suction unit; and the suction unit that rises as the suction unit is operated. Temperature detecting means for detecting temperature, and when the temperature detected by the temperature detecting means reaches a predetermined set operating temperature, the energization (operation) to the suction means by the energizing means is stopped, and the suction For example, when the distance between the temperature detection means and the suction means is increased, the temperature detected by the temperature detection means is set to a predetermined value. If the time is increased until the operating temperature is reached, that is, the operation time of the main body can be extended, and conversely, if the distance between the temperature detecting means and the suction means is reduced, the temperature detecting means The time until the detected temperature reaches the set operating temperature can be shortened, that is, the operation time of the main body can be shortened. Therefore, the operation time can be set without expensive timer means, and the entire product can be set. Since the structure can be simplified and the entire product can be made compact and inexpensive, an oxygen enricher that is easily available to the user can be provided.

  In particular, the second invention includes, in addition to the configuration of the first invention, a cooling means for cooling the suction means, and a cooling capacity variable means capable of changing the cooling capacity of the cooling means, and cooling by the cooling means. The capability can be changed, and when the temperature detected by the temperature detection means reaches a predetermined set operating temperature, the energization (operation) to the suction means by the energization means is stopped. For example, the cooling capacity When the cooling capacity of the cooling means is increased by the variable means, the temperature rise rate of the suction means becomes slow, and the time until the temperature detected by the temperature detecting means reaches a predetermined set operating temperature is extended, that is, the operation time of the main body Conversely, if the cooling capacity of the cooling means is lowered by the cooling capacity variable means, the temperature rise speed of the suction means increases and is detected by the temperature detecting means. The time until the temperature reaches the preset operating temperature can be shortened, that is, the operating time of the main body can be shortened, so that the operating time can be set even without expensive timer means, and the overall configuration of the product is simplified. The entire product can be made compact and inexpensive. In addition, a small and low-priced pump with a maximum capacity can be used in the maximum load state, so that the price can be reduced.

  In the third invention, in particular, the cooling means of the second invention is formed by a fan motor, and the cooling loss by the fan motor is changed by changing the pressure loss of the air flow path through which the wind by the fan motor passes. For example, the opening area of the intake port for taking in cooling air provided in the main body can be changed by opening and closing the shutter, etc., and the operation of the shutter is mechanically operated with a lever for operating time setting etc. If it is made to link with, the operation time can be changed by changing the pressure loss of the air flow path and thus changing the cooling capacity with an inexpensive configuration without using a complicated microcomputer.

  In the fourth invention, in particular, the energizing means of any one of the first to third inventions is a relay having an exciting coil, and the temperature detecting means is composed of a thermo protector, and the thermo protector is connected in series to the exciting coil. Because the power supply of the main body is shut off when the temperature detected by the temperature detection means reaches the preset operating temperature without using an expensive control circuit such as a microcomputer, the price of the main unit is reduced. Thus, it is possible to provide an oxygen enricher that contributes to energy savings through downsizing and further standby power consumption of 0 W.

The oxygen-enriched membrane unit is composed of a flat membrane (not shown) of an organic polymer, and utilizes the difference in the speed of molecules passing through the flat membrane, and allows oxygen to pass more than nitrogen in the air. By passing air through the flat membrane, air having a relatively high oxygen concentration, that is, oxygen-enriched air is obtained. In ordinary air, the proportion of oxygen is about 21% (nitrogen is about 79%), but the proportion of oxygen in the oxygen-enriched air after passing through the oxygen-enriching means 2 of the present embodiment is about 30%. % (About 70% nitrogen).

  The suction means 3 provided inside the main body 1 is composed of a high-pressure type small and low-priced pump (not shown). Outside air is sucked through the oxygen enrichment means 2, and oxygen-enriched air generated through the oxygen enrichment means 2 is sent to the main body discharge port 5 provided on the side surface of the main body 1. Reference numeral 18 denotes a headset attached to the user's head, one end of which is connected to the main body discharge port 5 via the tube 6 and the other end includes discharge means 7 for discharging oxygen-enriched air to the user's mouth. ing.

  The suction means 3 is controlled by energization means 8 comprising a switch 8a and a relay 8b, and is energized (running) and stopped by an operation by the user. Further, air that does not pass through the oxygen-enriched membrane unit of the oxygen-enriching means 2, that is, nitrogen-enriched air having a reduced oxygen content and a high nitrogen concentration is discharged from the exhaust port 9 provided on the side surface of the main body 1 to the outside. It is discharged to the person side.

  Inside the main body 1, a cooling means 10 including a fan motor for cooling the suction means 3 is disposed. In addition, a slide switch 11 for setting the operation time is provided on the back of the main body 1 so that the user can freely select the operation time of the main body 1. Inside the main body 1 of the slide switch 11 is provided a temperature detection means 12 that is made of a thermo protector or the like and detects the temperature of the suction means 3, and moves in conjunction with the slide switch 11 to move the temperature detection means 12. The distance is variable. The temperature detection means 12 is connected in series with the excitation coil 18c.

  The operation and action of the oxygen enricher in the present embodiment configured as described above will be described below.

  First, the user wears the headset 18 having the discharge means 7 as shown in FIG. 4, and operates the slide switch 11 for determining the operation time to set an arbitrary operation time. Then, when the operation is started by operating the energization means 8, the suction means 3 is driven by the relay 8 b constituting the energization means 8, and the oxygen-enriched air generated by the oxygen enrichment means 2 is passed through the tube 6. It is sent to the discharge means 7 and discharge of oxygen-enriched air to the user's nose is started. When the main body 1 is operated for a long time, the temperature of the suction means 3 rises, and when the temperature reaches a predetermined set operating temperature 13 of the temperature detection means 12, the temperature detection means 12 operates to The energization to the exciting coil 8c of the relay 8b is cut off, the energization of the suction means 3 by the energizing means 8 is stopped, and the operation of the main body 1 is stopped.

  At this time, between the suction means 3 and the temperature detection means 12, the predetermined setting operation temperature 13 at which the temperature detection means 12 operates so that the operation of the main body 1 is stopped in the operation time set by the user with the slide switch 11. Is adjusted in advance. FIG. 5 is a diagram showing the relationship between the predetermined set operating temperature 13 of the temperature detection means 12 and the detected temperature of the temperature detection means 12 and the operation time at the distance between the suction means 3 and the temperature detection means 12. The distance between the suction means 3 and the temperature detection means 12 is the closest to the curve L1, and the farthest is the curve L3.

  The longer the distance between the suction means 3 and the temperature detection means 12, the longer the time until the temperature detection means 12 detects the predetermined set operating temperature 13. By utilizing this characteristic, the location of the temperature detection means 12 can be moved in conjunction with the movement of the slide switch 11, thereby making it possible to set an arbitrary operation time. In this way, the operating time can be set even without expensive timer means such as a microcomputer to realize the timer function, so the overall configuration of the oxygen enricher can be simplified and the entire product can be made compact. Moreover, it can be formed at a low cost.

  In addition, since the relay 8b is used as the energizing means 8 and the temperature detecting means 12 is connected in series to the exciting coil 8c of the relay 8b, when the temperature detecting means 12 reaches the predetermined set operating temperature 13, the energizing means 8 As a result, all the electric power of the oxygen enricher is cut off, so that zero standby power can be realized and energy saving can be realized.

(Embodiment 2)
6 (a) and 6 (b) are a side view and a rear view of the main body of the oxygen enricher according to the second embodiment of the present invention, and FIG. 7 is a temperature detection means in the opening area of the intake port of the oxygen enricher. FIG. 4 is a graph showing the relationship between the temperature of the suction means and the operating time. In addition, about the same part as the oxygen enricher in the said 1st Embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted, and only a structure, operation | movement, and effect | action of a different part are demonstrated.

  In the present embodiment, temperature detection means 12 for detecting the temperature of the suction means 3 is provided in the vicinity of the suction means 3, and a slide for the user to arbitrarily set the operation time of the main body 1 on the back of the main body 1. A switch 11 is provided, and a shutter 14 (cooling capacity variable means) that moves in conjunction with the movement of the slide switch 11 and changes the opening area of the intake port 4 is provided on the inside of the main body of the slide switch 11.

  The relationship between the opening area of the intake port 4 and the shutter 14 is that the opening area of the intake port 4 becomes the largest when the slide switch 11 is arranged at the position “30 minutes” in FIG. Is moved upward and the shutter 14 is moved so that the opening area of the intake port 4 becomes the smallest when it is placed at the position of “10 minutes”.

  First, when the operation of the main body 1 is started, the temperature of the suction means 3 rises as the operation time elapses. When the temperature reaches the predetermined operating temperature 13 of the temperature detection means 12, the temperature detection means 12 works to The energization of the exciting coil 8c of the relay 8b of the means 8 is stopped, and the energization of the suction means 3 by the energizing means 8 is stopped, whereby the operation of the oxygen enricher is stopped. At this time, the air volume of the cooling means 10 that cools the suction means 3 is adjusted by moving the shutter 14 so that the oxygen enrichment machine stops at the operation time set by the user. Thus, the cooling capacity is changed to change the time required for the temperature detecting means 12 to reach the predetermined set operating temperature 13.

  FIG. 7 is a diagram showing the relationship between the detected temperature of the temperature detecting means 12 and the operation time in the opening area of the intake port 4. The curve A1 has the smallest opening area of the intake port 4, and the curve A3 has the largest opening area. The larger the opening area of the intake port 4 is, the longer it takes to reach the predetermined operating temperature 13 of the temperature detecting means 12. That is, the pressure loss of the air flow path is small and the cooling capacity is high. Utilizing this characteristic, by changing the opening area of the intake port 4 with the shutter 14, the air volume of the cooling means 10 for cooling the suction means 3 can be changed, and the operation time can be freely set. In this way, even if there is no expensive timer means such as a microcomputer to realize the timer function, it is possible to set the operation time, so the overall configuration of the product can be simplified, so the entire product can be made compact, It can be made cheap.

  Further, when the temperature detecting means 12 reaches a predetermined set operating temperature by connecting the temperature detecting means 12 in series with the energizing path of the exciting coil 8c of the relay 8b using the relay 8b as the energizing means 8, the energizing means. 8, since all the power of the device is cut off, zero standby power can be realized and energy saving can also be realized.

(Embodiment 3)

It is a relationship figure of the temperature of the attraction | suction means by the cooling means in the rotation speed of the cooling means of the oxygen enricher, and operation time. In addition, about the same part as the oxygen enricher in the said embodiment, the same code | symbol is attached | subjected and the description is abbreviate | omitted, and only a structure, operation | movement, and effect | action of a different part are demonstrated.

  In the present embodiment, as shown in FIG. 8, a variable resistor 15 (cooling capacity varying means) for changing the number of revolutions of the cooling means 10 and a rear surface of the main body 1 are arranged, and the user sets the operation time. The slide switch 11 is provided so that the user can select the operation time of the device. Inside the main body 1, a slide piece (not shown) that changes the resistance of the variable resistor 15 is configured to move in conjunction with the operation of the slide switch 11.

  Specifically, when the slide switch 11 is set to the position “30 minutes” in FIG. 9, the resistance of the variable resistor 15 is the smallest and the rotation speed of the cooling means 10 is the fastest. Then, when the slide switch 11 is slid upward and set to the position of “10 minutes”, the resistance of the variable resistor 15 becomes the largest and the rotational speed of the cooling means 10 becomes the slowest. Yes.

  First, when the operation of the main body 1 is started, the temperature of the suction means 3 rises as the operation time elapses. When the temperature reaches the predetermined operating temperature 13 of the temperature detection means 12, the temperature detection means 12 works to The energization to the exciting coil 8c of the relay 8b of the means 8 is cut off. As a result, the energization to the suction means 3 is stopped and the operation of the main body 1 is stopped. At this time, the air volume of the cooling means 10 that cools the suction means 3 is changed by adjusting the number of rotations of the cooling means 10 so that the operation of the main body 1 is stopped in the operation time set by the user, thereby cooling. It is possible to change the time to change the time for reaching the predetermined set operating temperature 13 of the temperature detecting means 12.

  FIG. 10 is a diagram showing the relationship between the detected temperature detected by the temperature detecting means 12 and the operation time at the rotation speed of the cooling means 10. The curve R1 has the slowest rotation speed of the cooling means 10, and the curve R3 has the fastest rotation speed. The faster the rotation speed of the cooling means 10, the longer it takes for the temperature detected by the temperature detecting means 12 to reach the predetermined set operating temperature 13. By utilizing this characteristic, by changing the number of rotations of the cooling means 10, the air volume of the cooling means 10 for cooling the suction means 3 can be changed, and an arbitrary operation time can be set.

  As described above, according to the present embodiment, the operation time can be set even without expensive timer means such as a microcomputer for realizing the timer function, and the overall configuration of the oxygen enricher is simplified. Therefore, the entire product can be made compact and provided at low cost.

  Further, by using the relay 8b as the energizing means 8 and arranging the temperature detecting means 12 in series with the energizing path of the exciting coil 8c of the relay 8b, the temperature detected by the temperature detecting means 12 reaches the predetermined set operating temperature 13. In this case, since all the power of the oxygen enricher is cut off by the energizing means 8, zero standby power can be realized and energy saving can be realized.

  As described above, the oxygen enricher according to the present invention simplifies the overall product configuration, can be made compact, and can reduce the manufacturing cost and the unit price of the product. It can also be applied to embedded applications.
