Description

The present invention relates to a method for stopping water in a liquid miniaturization device.

Conventionally, there is a liquid miniaturization device that miniaturizes water, impregnates the sucked air with the miniaturized water, and blows it out (for example, Patent Document 1). In such a liquid miniaturization device, a liquid miniaturization chamber for refining water is provided in an air passage between a suction port for sucking air and an outlet for blowing out the sucked air. The liquid miniaturization chamber is equipped with a pumping pipe fixed to the rotating shaft of the rotary motor, and when the pumping pipe is rotated by the rotary motor, the water stored in the water storage section is pumped by the pumping pipe and pumped. Water is radiated in the centrifugal direction. When this radiated water collides with the collision wall, the water is made finer.

Further, in the conventional liquid miniaturization device, a drain pipe for discharging the water stored in the water storage section after the operation is completed is connected to the bottom surface of the water storage section. A drain valve is provided in this drain pipe, and the drain valve is closed during the operation of the liquid miniaturization device, while the drain valve is opened after the operation is completed, and the water in the water storage section is discharged.

Japanese Unexamined Patent Publication No. 2009-279514

However, in the conventional liquid miniaturization device, since the water stop mechanism of the drain pipe is realized in a small size, the gap through which water can pass inside the drain valve becomes narrow, and there is a problem that clogging is likely to occur due to dust contained in the water. was there.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a water stopping method using a liquid miniaturization device capable of realizing a drainage mechanism in which clogging is less likely to occur.

In order to achieve this object, the water stopping method of the liquid miniaturization device of the present invention has a pumping port downward in the vertical direction, and discharges the water pumped from the pumping port in the centrifugal direction in accordance with the rotation of the rotating shaft. A liquid miniaturization device provided with a tubular pumping pipe, a water storage unit provided vertically below the pumping pipe to store water pumped from the pumping port, and a drainage port for draining water at the bottom surface of the water storage unit. In this method of stopping water, a vortex is generated in the water of the water storage part by rotation inside the pumping pipe, and a gap communicating between the pumping port and the drainage port is formed at the center of the vortex to allow the water in the water storage part to flow. It stops the water from being drained from the drain port.

According to the water stopping method of the liquid miniaturization device of the present invention, a vortex is generated in the water of the water storage portion inside the pumping pipe due to the rotation of the pumping pipe performed for the miniaturization of water, and the vortex is formed at the bottom of the center of the vortex. A void is formed between the drain and the drain. As a result, it is possible to prevent the water in the water storage unit from being drained from the drain port during the operation of the liquid miniaturization device. On the other hand, when the rotation of the pumping pipe is stopped, the water in the water storage section flows into the drainage port. As a result, when the operation of the liquid miniaturization device is stopped, the water in the water storage section can be drained. In this way, even if a drain valve is not used for the drainage mechanism, the water in the water storage section can be suppressed from being drained from the drain port during operation, and the water in the water storage section can be drained from the drain port after the operation is stopped. It has the effect of eliminating the need for a drain valve and realizing a drain mechanism that is less likely to cause clogging.

Therefore, among the components in the following embodiments, the components not described in the independent claims indicating the highest level concept of the present invention will be described as arbitrary components. Further, in each figure, the same reference numerals are given to substantially the same configurations, and duplicate explanations will be omitted or simplified.

(First Embodiment)
First, the schematic configuration of the liquid miniaturization apparatus 50 according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic cross-sectional view of the liquid miniaturization device 50 in the vertical direction. FIG. 2 is an explanatory diagram for explaining the operating principle of the liquid miniaturization device 50.

The liquid miniaturization device 50 includes a suction port 2 for sucking air and an outlet 3 for blowing out the air sucked from the suction port 2, and the suction port 2 and the outlet 3 are provided in the liquid miniaturization device 50. An air passage 15 to 17 is formed between the air passage and the air passage. Further, the liquid miniaturization device 50 includes a liquid miniaturization chamber 1 provided in the air passages 15 to 17, and the suction port 2, the liquid miniaturization chamber 1, and the air outlet 3 communicate with each other.

The liquid miniaturization chamber 1 is a main part of the liquid miniaturization device 50, and is a place where water is miniaturized. In the liquid miniaturization device 50, the air taken in by the suction port 2 is sent to the liquid miniaturization chamber 1 via the air passage 15. Then, the liquid miniaturization device 50 impregnates the air passing through the air passage 16 with the water refined in the liquid miniaturization chamber 1, and blows the air containing the water via the air passage 17. It is configured to blow out from the exit 3.

The liquid miniaturization chamber 1 is provided with a collision wall 12 having an opening above and below. The collision wall 12 is provided by being fixed in the liquid miniaturization chamber 1. Further, the liquid miniaturization chamber 1 is provided with a cylindrical pumping pipe 11 that pumps (pumps) water while rotating inside the inside surrounded by the collision wall 12. The pumping pipe 11 has an inverted conical hollow structure, is provided with a circular pumping port 21 (see FIG. 2) below, and is located above the pumping pipe 11 and at the center of the inverted conical top surface. A rotating shaft 10 arranged in the vertical direction is fixed. By connecting the rotary shaft 10 to the rotary motor 9 provided on the outer surface of the liquid miniaturization chamber 1, the rotational motion of the rotary motor 9 is conducted to the pumping pipe 11 through the rotary shaft 10, and the pumping pipe 11 rotates. ..

As shown in FIG. 2, the pumping pipe 11 includes a plurality of rotating plates 14 formed so as to project outward from the outer surface of the pumping pipe 11. The plurality of rotating plates 14 are formed so as to project outward from the outer surface of the pumping pipe 11 at predetermined intervals in the axial direction of the rotating shaft 10. Since the rotary plate 14 rotates together with the pumping pipe 11, a horizontal disk shape coaxial with the rotary shaft 10 is preferable. The number of rotating plates 14 is appropriately set according to the target performance and the dimensions of the pumping pipe 11.

Further, the wall surface of the pumping pipe 11 is provided with an opening 13 penetrating the wall surface of the pumping pipe 11. The opening 13 of the pumping pipe 11 is provided at a position communicating with a rotating plate 14 formed so as to project outward from the outer surface of the pumping pipe 11. The size of the opening 13 in the circumferential direction needs to be designed according to the outer diameter of the portion of the pumping pipe 11 provided with the opening 13, and corresponds to, for example, 5% to 50% of the outer diameter of the pumping pipe 11. The diameter, more preferably the diameter corresponding to 5% to 20% of the pumping pipe 11. Within the above range, the dimensions of each opening 13 may be the same.

As shown in FIG. 1, in the lower part of the liquid miniaturization chamber 1, a water storage unit 4 for storing water pumped by the pumping pipe 11 is provided below the pumping pipe 11 in the vertical direction. The water storage unit 4 is deepened so that a part of the lower part of the pumping pipe 11, for example, a length of about one-third to one-hundredth of the height of the cone of the pumping pipe 11 is immersed. This depth can be designed according to the required pumping volume. Further, the bottom surface of the water storage unit 4 is formed in a mortar shape toward the drainage port 22 (see FIG. 3) described later.

Water is supplied to the water storage unit 4 by the water supply unit 7. A water supply pipe (not shown) is connected to the water supply unit 7, and water is directly supplied from the water supply through a water pressure adjusting valve, for example, through the water supply pipe. The water supply unit 7 may be configured to pump up only the amount of water required by the siphon principle from a water tank provided in advance outside the liquid miniaturization chamber 1 and supply water to the water storage unit 4.

The liquid miniaturization chamber 1 is provided with a water level detecting unit 8 for detecting the water level of the water storage unit 4. The water level detection unit 8 has a float switch 20. The float switch 20 is turned off when the water storage unit 4 has not reached a constant water level, and is turned on when the water storage unit 4 has reached a constant water level. This constant water level is set so that the lower part of the pumping pipe 11 is immersed in the water stored in the water storage unit 4. When the float switch 20 is off, water is supplied from the water supply unit 7 to the water storage unit 4, and when the float switch 20 is on, the water supply from the water supply unit 7 to the water storage unit 4 is stopped. The water in the water storage unit 4 can be kept at a constant water level.

A drainage pipe 18 is connected to the bottom surface of the water storage unit 4. The circular drainage port 22 (see FIG. 3) provided at a position where the drainage pipe 18 is connected is provided at the lowest position on the bottom surface of the water storage portion 4 formed in a mortar shape. Water stoppage and drainage by the drainage pipe 18 are realized by rotation of the pumping pipe 11. That is, the drainage pipe 18 and the pumping pipe 11 constitute a water stopping mechanism and a pumping mechanism of the water storage unit 4. The details of the water stop mechanism and the drainage mechanism of the water storage unit 4 by the drainage pipe 18 and the pumping pipe 11 will be described later with reference to FIG.

Here, the operating principle of water miniaturization in the liquid miniaturization apparatus 50 will be described. When the rotary shaft 10 is rotated by the rotary motor 9 and the pumping pipe 11 is rotated in accordance with the rotation, the water stored in the water storage unit 4 is pumped up by the pumping pipe 11 due to the centrifugal force generated by the rotation. The rotation speed of the pumping pipe 11 is set between 1000 and 5000 rpm. Since the pumping pipe 11 has an inverted conical hollow structure, the water pumped up by rotation is pumped upward along the inner wall of the pumping pipe 11. Then, the pumped water is discharged in the centrifugal direction from the opening 13 of the pumping pipe 11 through the rotating plate 14, and is scattered as water droplets.

The water droplets scattered from the rotating plate 14 fly in the space surrounded by the collision wall 12, collide with the collision wall 12, and are miniaturized. On the other hand, the air passing through the liquid miniaturization chamber 1 moves from the upper opening of the collision wall 12 to the inside of the collision wall 12, and contains water droplets crushed (miniaturized) by the collision wall 12 from the lower opening to the collision wall. 12 Move to the outside. As a result, the air sucked from the suction port 2 of the liquid miniaturization device 50 can be humidified, and the humidified air can be blown out from the outlet 3.

Since the kinetic energy of the water scattered from the rotating plate 14 is attenuated by friction with the air inside the collision wall 12, it is preferable that the rotating plate 14 is as close to the collision wall 12 as possible. On the other hand, as the collision wall 12 and the rotating plate 14 are brought closer to each other, the amount of air passing through the inside of the collision wall 12 decreases. Therefore, the lower limit of the distance is arbitrarily determined by the pressure loss and the amount of air passing through the inside of the collision wall 12.

The liquid to be refined may be other than water, and may be, for example, a liquid such as hypochlorite water having bactericidal / deodorant properties. By including the miniaturized hypochlorite water in the air sucked from the suction port 2 of the liquid miniaturization device 50 and blowing out the air from the air outlet 3, the space where the liquid miniaturization device 50 is placed is placed. Can be sterilized / deodorized.

Next, with reference to FIG. 3, the details of the water stop mechanism and the drainage mechanism of the water storage unit 4 by the drainage pipe 18 and the pumping pipe 11 will be described. FIG. 3 is a diagram for explaining a water stop mechanism of the water storage unit 4 by the drainage pipe 18 and the pumping pipe 11.

When the liquid miniaturization device 50 is in the operating state and the pumping pipe 11 is rotated, a vortex 24 is generated in the water of the water storage unit 4 inside the pumping pipe 11 due to the centrifugal force of the rotation. Then, the pumping pipe 11 forms a gap 25 between the vortex center bottom portion 23 generated by the rotation thereof and the drainage port 22 to which the drainage pipe 18 is connected. As a result, it is possible to prevent the water in the water storage unit 4 from being drained from the drain port 22 during the operation of the liquid miniaturization device 50.

On the other hand, when the rotation of the pumping pipe 11 is stopped, the water of the water storage unit 4 flows into the drain port 22. As a result, when the operation of the liquid miniaturization device 50 is stopped, the water in the water storage unit 4 can be drained from the drain port 22.

In this way, even if a drain valve is not used for the drain pipe 18, the water of the water storage unit 4 is suppressed (stopped) from being drained from the drain port 22 during the operation of the liquid miniaturization device 50, and after the operation is stopped. Can drain the water of the water storage unit 4 from the drain port 22. Therefore, the liquid miniaturization device 50 can eliminate the need for a drain valve, and as a result, the area of the drain port 22 can be increased and the drain pipe 18 can be made thicker, so that a drain mechanism that is less likely to be clogged can be realized.

Further, in the present embodiment, the bottom surface of the water storage unit 4 is formed in a mortar shape toward the drain port 22. As a result, when the pumping pipe 11 rotates, centrifugal force can be easily applied to the water stored in the water storage unit 4, and a vortex 24 can be easily generated in the water of the water storage unit 4 inside the pumping pipe 11. The generated vortex 24 can be stably maintained. Further, when the rotation of the pumping pipe 11 is stopped, the water stored in the water storage unit 4 can be reliably drained from the drain port 22.

Here, with reference to FIG. 4, the positional relationship between the pumping port 21 and the drainage port 22 of the pumping pipe 11 will be described. FIG. 4A is a schematic diagram showing an example of the positional relationship between the pumping port 21 and the drainage port 22 when the pumping pipe 11 is viewed from above in the vertical direction, and FIG. 4B is a schematic diagram showing the position. It is a schematic diagram which showed another example of a relationship.

In the example shown in FIG. 4A, the drainage port 22 is arranged so as to be inside the pumping port 21. Thereby, the gap 25 of the water vortex center bottom portion 23 generated inside the pumping pipe 11 in the water storage portion 4 due to the rotation of the pumping pipe 11 can be easily formed up to the drain port 22. Therefore, while the liquid miniaturization device 50 is in operation, drainage from the drain port 22 can be reliably stopped. Note that FIG. 4A shows a case where the center of the pumping port 21 and the center of the drainage port 22 are displaced from each other when the pumping pipe 11 is viewed from above in the vertical direction. It is more preferable that the center of the mouth 21 and the center of the drain port 22 are arranged so as to coincide with each other, that is, the pump port 21 and the drain port 22 are arranged concentrically.

Further, as in another example shown in FIG. 4B, the pumping port 21 and the drainage port 22 may be arranged so as to overlap each other. In this case, a gap 25 at the bottom 23 of the center of the vortex of water generated inside the pumping pipe 11 in the water storage portion 4 due to the rotation of the pumping pipe 11 can be formed between at least a part of the drainage port 22. Therefore, during the operation of the liquid miniaturization device 50, although the water cannot be completely stopped, the amount of water drained from the drain port 22 can be suppressed by the void 25 formed on the drain port 22.

In order to form a gap 25 between the vortex center bottom 23 generated by the rotation of the pumping pipe 11 and the drainage port 22 to which the drainage pipe 18 is connected, the diameter of the pumping port 21 is the diameter of the drainage port 22. The larger the value, the better. For example, when the diameter of the drainage port 22 is 1, it is preferable that the diameter of the pumping port 21 is 1.3 or more. This is because the larger the diameter of the pumping port 21, the larger the void 25 generated inside the pumping pipe 11 in the water storage section 4 due to the rotation of the pumping pipe 11, and the gap 25 can be easily formed between the pumping port 21 and the drain port 22. be.

Further, in order to form a gap 25 between the vortex center bottom portion 23 generated by the rotation of the pumping pipe 11 and the drainage port 22 to which the drainage pipe 18 is connected, the area of the pumping port 21 is reduced to the drainage port 22. The larger the area, the better. For example, when the area of the drainage port 22 is 1, the diameter of the pumping port 21 is preferably 1.7 or more. This is because the larger the area of the pumping port 21, the larger the void 25 generated inside the pumping pipe 11 in the water storage section 4 due to the rotation of the pumping pipe 11, and the gap 25 can be easily formed between the pumping port 22 and the drainage port 22. be.

The shape of the drainage port 22 does not necessarily have to be circular, and may be polygonal.

FIG. 5 is a schematic perspective view of a heat exchange air device 60 provided with a liquid miniaturization device 50 according to the first embodiment of the present invention. The heat exchange air device 60 includes an indoor suction port 61 and an air supply port 64 provided inside the building, an exhaust port 62 and an outside air suction port 63 provided outside the building, and heat exchange provided inside the main body. It includes an element 65.

The indoor suction port 61 sucks in the indoor air, and the sucked air is exhausted to the outside through the exhaust port 62. Further, the outside air suction port 63 sucks the outdoor outside air, and the sucked outside air is supplied to the room through the air supply port 64. At this time, heat exchange is performed by the heat exchange element 65 between the air sent from the indoor suction port 61 to the exhaust port 62 and the outside air sent from the outside air suction port 63 to the air supply port 64.

As one of the functions of the heat exchange air device, there is a device incorporating a device for vaporizing a liquid such as a water vaporizer for humidification purpose and a hypochlorous acid vaporizer for sterilization / deodorization purpose. The heat exchange air device 60 incorporates a liquid miniaturization device 50 as a device for vaporizing this liquid. Specifically, a liquid miniaturization device 50 is provided on the air supply port 64 side of the heat exchange air device 60. The water supply and drainage to the liquid miniaturization device 50 is performed by the water supply / drainage pipe 51.

The heat exchange air device 60 provided with the liquid micronizer 50 includes water or hypochlorite refined by the liquid minerizer 50 with respect to the outside air heat exchanged by the heat exchange element 65. It is supplied indoors from the air supply port 64. By using the liquid miniaturization device 50 as a mechanism for vaporizing these liquids, a smaller and energy-efficient heat exchange air device 60 can be obtained.

The liquid miniaturization device 50 may be provided in an air purifier or an air conditioner instead of the heat exchange air device 60. As one of the functions of an air purifier or an air conditioner, there is a built-in device for vaporizing a liquid such as a water vaporizer for humidification and a hypochlorite vaporizer for sterilization / deodorization. By using the liquid miniaturization device 50 as this device, it is possible to obtain a smaller and energy-efficient air purifier or air conditioner.

(Second Embodiment)
In the second embodiment, a structure of a pumping pipe 11 (specifically, a vortex 24 is generated in the water of the water storage portion 4 by rotation, and a gap 25 is formed between the vortex center bottom portion 23 and the drain port 22 to stop the water. The structure of the tip of the pumping pipe 11) is different from that of the first embodiment. The configuration of the liquid miniaturization device 50 other than the structure of the tip portion of the pumping pipe 11 is the same as that of the first embodiment (FIGS. 1 and 2). Hereinafter, the contents described in the first embodiment will be omitted again as appropriate, and the differences from the first embodiment will be mainly described.

With reference to FIGS. 6 to 8, the schematic configuration of the tip end portion of the pumping pipe 11 in the liquid miniaturization apparatus 50 according to the second embodiment of the present invention will be described. FIG. 6 is a schematic perspective view of the tip end portion of the pumping pipe 11. FIG. 7A is a schematic perspective view of a cross section of the tip of the pumping pipe 11, and FIG. 7B is a schematic side view of a cross section of the tip of the pumping pipe 11. 8 (a) is a schematic view of the pumping pipe 11 in the AA'cross section of FIG. 7 (b), and FIG. 8 (b) is the pumping in the BB' cross section of FIG. 7 (b). It is a schematic diagram of a tube 11.

As shown in FIG. 6, the pumping pipe 11 of the liquid miniaturization apparatus 50 according to the second embodiment is located at the tip of the pumping pipe 11 as a pumping port for pumping water from the water storage unit 4 during a rotational operation. It has a first pumping port 21a and a second pumping port 21b located above the first pumping port 21a. The second pumping port 21b is formed not only at the position of the first pumping port 21a but also above the position where the rib portion 26 described later is formed.

The first pumping port 21a is a pumping port corresponding to the pumping port 21 in the first embodiment, and is formed in a circular shape reflecting the inverted conical hollow structure of the pumping pipe 11.

The second pumping port 21b is a rectangular opening, and is formed on the wall surface of the pumping pipe 11 so as to penetrate the wall surface. A plurality of second pumping ports 21b are formed in the circumferential direction of the wall surface of the pumping pipe 11. In the present embodiment, as shown in FIG. 8A, the second pumping port 21b having the same shape is formed at three locations in the circumferential direction of the pumping pipe 11. The total opening area of the second pumping port 21b in the circumferential direction includes the pumping capacity of the first pumping port 21a (the amount of pumped water from the first pumping port 21a) and the pumping capacity of the second pumping port 21b (the second pumping port). It is designed in consideration of the amount of pumped water from 21b).

As shown in FIGS. 7 (a) and 7 (b), the pumping pipe 11 has a plurality of rib portions 26 on the wall surface (inner wall 11a side) between the first pumping port 21a and the second pumping port 21b. It is formed. The rib portion 26 has a pillar shape and is formed so as to project from the inner wall 11a of the pumping pipe 11 toward the center side of the pumping pipe 11. Further, a plurality of rib portions 26 are formed in the circumferential direction of the inner wall 11a of the pumping pipe 11. In the present embodiment, as shown in FIG. 8B, rib portions 26 having the same shape are formed at eight locations in the circumferential direction of the inner wall 11a. The dimensions, shape, number, arrangement, etc. of the rib portions 26 are designed in consideration of the water stopping capacity of the pumping pipe 11.

Next, with reference to FIG. 9, the details of the water stop mechanism of the water storage unit 4 by the drain pipe 18 and the pumping pipe 11 in the liquid miniaturization device 50 according to the second embodiment will be described. FIG. 9 is a diagram for explaining a water stop mechanism of the water storage unit 4 by the drain pipe 18 and the pumping pipe 11 in the liquid miniaturization device 50.

As described in the first embodiment, when the liquid miniaturization device 50 is in the operating state and the pumping pipe 11 is rotated, the centrifugal force of the rotation causes the water in the water storage unit 4 to be swirled 24 inside the pumping pipe 11. Occurs. Then, the pumping pipe 11 forms a gap 25 between the vortex center bottom portion 23 generated by the rotation thereof and the drainage port 22 to which the drainage pipe 18 is connected. As a result, it is possible to prevent the water in the water storage unit 4 from being drained from the drain port 22 during the operation of the liquid miniaturization device 50 (see FIG. 3).

In the present embodiment, as shown in FIG. 9, a plurality of rib portions 26 are formed at the tip end portion of the pumping pipe 11 in the circumferential direction of the inner wall 11a of the pumping pipe 11. The plurality of rib portions 26 push the water in the region in the rotational direction by the rotation of the pumping pipe 11, and it becomes easy to apply a centrifugal force to the water in this region, so that a vortex 24 is generated in the water in this region. It can be made easy. That is, if the rotation operation (rotation speed) of the pumping pipe 11 is the same, the vortex 24 generated by the rib portion 26 can be strengthened. As a result, the gap 25 generated between the bottom 23 of the vortex center generated by the rotation and the drainage port 22 to which the drainage pipe 18 is connected is strengthened, and the force (stop) for suppressing the amount of water drained from the drainage port 22 is enhanced. (Hydropower) improves. In particular, this effect of improving the water stopping force is remarkable when the pumping pipe 11 operates at a low rotation speed.

On the other hand, the operation when the rotation of the pumping pipe 11 is stopped is the same as that of the first embodiment, and thus the description thereof will be omitted.

Next, the pumping by the pumping pipe 11 of the liquid miniaturization apparatus 50 according to the second embodiment will be described with reference to FIG.

As described in the first embodiment, in the liquid miniaturization apparatus 50, when the rotary shaft 10 is rotated by the rotary motor 9 and the pumping pipe 11 is rotated in accordance with the rotation, the centrifugal force generated by the rotation causes the water storage unit 4 to rotate. The stored water is pumped up by the pumping pipe 11. Since the pumping pipe 11 has an inverted conical hollow structure, the water pumped from the pumping port 21 of the pumping pipe 11 by rotation is pumped upward along the inner wall of the pumping pipe 11 (FIG. 2). reference).

In the present embodiment, as shown in FIG. 9, the pumping pipe 11 has a first pumping port 21a and a second pumping port 21b as a pumping port. The water pumped from each of the first pumping port 21a and the second pumping port 21b of the pumping pipe 11 by rotation is pumped upward along the inner wall of the pumping pipe 11. In particular, since the second pumping port 21b is provided above the region where the vortex 24 is created (the region of the first pumping port 21a and the rib portion 26), water is pumped regardless of the strength of the vortex 24 in the region. 11 It is easy to take in inside. Further, in the present embodiment, the total amount of pumped water is increased by the amount of the second pumping port 21b as compared with the pumping port of the first embodiment, so that stable operation of the liquid miniaturization device 50 is realized. be able to.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and it is easy to make various improvements and modifications without departing from the spirit of the present invention. It can be inferred. For example, the numerical values given in the above embodiment are examples, and it is naturally possible to adopt other numerical values.

An example in which the liquid miniaturization device 50 according to the first embodiment is applied as the heat exchange air device 60 provided with the liquid miniaturization device is shown, but the present invention is not limited to this. For example, the liquid miniaturization device 50 according to the second embodiment may be applied. This also makes it possible to obtain a smaller and more energy efficient heat exchange air device 60.
