Although a space is formed between the bottom plate 57 and the middle floor 86, since the wall 74 of the frame plate 69 is in contact with the lower surface of the middle floor 86, this space is formed between the space 88 outside the wall 74 and the wall 74. And a space 89 surrounded by. FIG. 8 shows the entire middle floor 86. A plurality of small openings 91 are formed in the vicinity of the sides of the middle floor 86 along the front and rear surfaces of the base 12, and the vicinity of the sides of the middle floor 86 along the side surfaces of the base 12 on the side of the frame plate 69. Is formed with a single large opening 92.

Referring again to FIGS. 1 to 3, the front and rear surfaces of the hood 13 have a double wall structure, and an opening 91 is located between the double walls. Inner wall 25 of base 12
Among them, a plurality of jacks 93 are attached at positions facing the plug 52 of the heating type humidifier 26 with some wobble, and a Hall element 94 is attached at a position facing the magnet 51 of the steam tower 44. ing. Further, an engaging portion 95 that engages with the other end 55 of the lever 53 of the heated humidifier 26 is provided on the inner wall 25 of the base 12.

When using the incubator 11 having the above configuration, water is poured into the water storage tank 38 detached from the warming type humidifier 26, and the cap 41 is screwed into the opening 39 of the water storage tank 38. Then, with the cap 41 facing downward as shown in FIG. 5, the water storage tank 38 is attached to the warming type humidifier 26 as shown in FIG. By simply placing the cap 41 on the lower side as shown in FIG. 5, the valve 43 is pressed outward by the water in the water storage tank
1 is pressed against and closes the opening 42, so that water does not leak from the opening 42.

However, the water storage tank 38 is connected to the heating type humidifier 2.
6, the valve 43 is moved toward the inside of the water storage tank 38 by the columnar portion 35, as shown in FIGS.
The gap is formed between the opening 42 and the valve 43 by being pressed to a position where the opening 42 is not pressed. For this reason, water is poured from the inside of the water storage tank 38 onto the columnar portion 35 through the opening 42, and the water is poured into the circular portion 29, the connecting portion 32, the circular portion 31, and the cut 4.
6 and flows onto the heating section 36. Therefore, the circular portion 2
9, 31 and the connecting portion 32 are waterways. When the water is supplied into the water tank 28 to a predetermined depth reaching the cap 41, the injection of water from the water storage tank 38 onto the columnar portion 35 is automatically stopped.

The capacity of the water tank 28 including the rectangular portion above the gourd-shaped portion composed of the circular portions 29 and 31 and the connecting portion 32 is larger than the capacity of the water storage tank 38. For this reason, the water storage tank 38 is not attached to the warming type humidifier 26 in a normal posture, or for some other reason, the water from the water storage tank 38 into the water tank 28 at the predetermined depth described above. Without automatically stopping the supply of
Water does not overflow from the water tank 28 into the base 12.

When the water storage tank 38 is mounted on the warming type humidifier 26, the water storage tank 38 and the flanges 48 and 49 of the steam tower 44 cover the circular parts 29 and 31 and the connecting part 32 to prevent dust. Functions as a layer. Thereafter, as shown in FIG. 2, the door 24 is opened, and a warming humidifier 26 is mounted in the space 27. Since the plug 52 and the jack 93 are mounted with some wobble, even if there is some error in their mounting positions, they are automatically aligned with each other with the mounting of the humidifier 26, The plug 52 is normally inserted into the jack 93.

However, both the plug 52 and the jack 93 are provided in a plural number, and depending on an error in their mounting positions, a case where the frictional force when the plug 52 is inserted into the jack 93 may be large. For this reason, at the final stage of the mounting operation of the warming type humidifier 26 in the space 27, one end 54 of the lever 53 is pressed as shown by a dashed line in FIG. By the leverage principle by engaging with 95, the warming humidifier 26 is pushed into the space 27 and the plug 52 is securely inserted into the jack 93.

At the final stage of the mounting operation of the heating type humidifier 26 in the space 27, as shown in FIG.
Since the upper end portion 47 of 4 contacts the lower flange portion 84 and pushes up the valve 82, the upper lid portion 83 is pushed up.
Therefore, the upper lid portion 83 is separated from the bolt 77, the center hole 81 of the bolt 77 is opened, and the inside of the steam tower 44 and the space 88 communicate. The outer peripheral surface of the lower flange portion 84 is a slope 85
, The upper end 47 first comes into contact with the slope 85, and the upper end 47 smoothly pushes up the valve 82. Thereafter, as shown in FIG. 1, the door 24 is closed, and the operation buttons of the heating humidifier 26 and the heating device 63 are operated to supply power to the heating unit 36, the heating device 63, the sirocco fan 66 and the like. .

At this time, the heating type humidifier 26 is
Is not installed, or when the steam tower 44 is not installed in the heating unit 36 even when the heating humidifier 26 is installed, the magnetic field from the magnet 51 is not applied to the Hall element 94, and Since the voltage obtained by the element 94 does not reach the predetermined value and it is possible to detect the non-attachment, an alarm is issued. The fact that the frame plate 69 is not placed at a predetermined position on the upper surface of the bottom plate 57 indicates that the Hall element 68 and the magnet 7
3 and the middle floor 8 on the bottom plate 57.
6 is not disposed, the Hall element 61 and the magnet 87
Therefore, an alarm is issued in any case.

Steam is generated by the heating of the water by the heated heating unit 36. The flanges 48 and 49 of the water storage tank 38 and the steam tower 44 cover the circular portions 29 and 31 and the connecting portion 32. And functions as a water vapor shielding layer. For this reason, most of the steam is supplied to the space 88 through the steam tower 44 and the center hole 81, and the incubator 1
Each part in 1, especially an electric circuit part is hard to be affected by accident by water vapor, and the incubator 11 is hard to break down.

Since steam is supplied to the space 88 and the air is heated by the heater 63 supplied thereto in the space 88, the heated and humidified air is generated in the space 88 after all. Then, by the rotation of the supplied sirocco fan 66, an air flow from the space 89 to the space 88 is formed through the opening 71 of the frame plate 69, and the space 88 becomes positive pressure and the space 89 becomes negative pressure. Become.

For this reason, the heated humidified air in the space 88 is supplied between the front and rear double walls of the hood 13 through the opening 91 of the middle floor 86, and the space between these double walls is formed. The heated humidified air that has risen joins the upper surface of the hood 13 and is supplied to the housing space 14. The heated humidified air in the storage space 14 returns to the space 89 through the opening 92 of the middle floor 86, and the heated humidified air flows again into the space 88 through the opening 71 and is heated in the incubator 11. Humidified air circulates. Therefore,
The spaces 88 and 89 are passages for heated humidified air. In addition, fresh air is introduced into the space 89 from the outside of the incubator 11 through the openings 67 and 72.

By the way, since the steam generated by the warming type humidifier 26 is supplied to the space 88 through the center hole 81, much of the residual heat generated by the heating type humidifier 26 also passes through the center hole 81 together with the steam. Through the space 88. However, in a region extending from the periphery of the opening 59 in which the bolt 77 having the center hole 81 is inserted to the rear surface of the base 12, an aluminum radiator plate 75 is attached to the lower surface of the stainless steel bottom plate 57, and is made of aluminum. Is formed on the rear surface and a part of the bottom surface of the outer casing 15 made of steel, and the radiating plates 75 and 79 are spot-welded on the rear surface of the outer casing 15. And the thermal conductivity of aluminum is higher than the thermal conductivity of stainless steel and steel.

For this reason, the residual heat generated in the warming type humidifier 26 and supplied to the space 88 together with the water vapor is sequentially transferred from the space 88 to the bottom plate 57, the thermally conductive grease, the radiator plate 75 and the radiator plate 79. It is easy to conduct and be released to the outside of the incubator 11. Moreover, since the water storage tank 38 covers the circular portion 29 and the connecting portion 32, the water storage tank 38 and the water therein function as a heat insulating layer for heated water or steam. Therefore, the heating of the air due to the residual heat generated in the heating humidifier 26 is suppressed, and in the incubator 11, the accommodation space 1
The humidity of 4 is always kept almost constant by the humidifier 26,
The temperature of the accommodating space 14 is also constantly and accurately maintained by the heater 63.

FIG. 9 is a graph showing the elapsed time after the power supply was stopped for 5 minutes after the power supply was supplied to the heaters and the humidifiers of the five types of incubators in an environment at a temperature of 25 ° C. and a relative humidity of 50%. It shows the relationship with the temperature of the storage space. The temperature was measured at the mattress (not shown) placed on the bed.
10 cm above the midpoint. The first wattage in a to e indicates the heating capacity of the heater, and the next wattage indicates the heating capacity of the heating humidifier.

In the incubator (a), no structure for heat dissipation is employed. In the incubator of b, a radiating fan is provided for releasing residual heat generated by the warming humidifier to the outside of the incubator. c, the incubator 11 described above is used.
Are not used, but the position of the heat radiating plate 79 is open. In the incubators d and e, the thicknesses of the heat sinks 75 and 79 are 1 mm and 2 mm, respectively. Therefore, a to c are incubators to be compared, and d and e
Is the incubator 11 described above. From FIG. 9, it can be seen that in the incubator 11, the residual heat generated by the warming humidifier 26 is efficiently released to the outside of the incubator 11.

FIG. 10 shows that in the incubators a and e described above, the heater and the humidifier were supplied with power to bring the temperature of the accommodation space to 34 ° C., and the elapsed time after the power supply was stopped. The relationship with the temperature at the above-mentioned position of the accommodation space is shown.
From FIG. 10, it can be seen that in the incubator 11, the residual heat generated by the warming humidifier 26 is efficiently released to the outside of the incubator 11.

When the generation of water vapor in the humidifier 26 continues and the water in the water storage tank 38 runs out and the water level in the water tank 28 becomes lower than the top of the water level sensor 37, the water level sensor 37 issues an alarm. When supplying water to the water storage tank 38 or wiping the heated humidifier 26, the space 2
By performing the reverse of the above-mentioned operation of mounting the warming humidifier 26 in the inside 7, the warming humidifier 26 is detached from the space 27. Even if the heating type humidifier 26 is detached from the space 27, the heating of the air by the heating unit 63 is continued.

At the initial stage of the detaching operation of the humidifier 26 from the space 27, the upper end 47 of the steam tower 44 is
Since the pressing on the lower flange portion 84 is released, the valve 82 descends by its own weight as shown in FIG. For this reason, the upper lid 83 abuts on the bolt 77, the center hole 81 of the bolt 77 is closed by the upper lid 83, and the housing space 14 does not communicate with the outside world via the spaces 88 and 89, the center hole 81 and the space 27. . Therefore, the heated humidifier 26 is supplied with the heated humidified air to the housing space 14 in the mounted state, and the housing space 14 is not only maintained in the optimum environment, but also stored in the detached state of the heated humidifier 26. The space 14 does not easily fluctuate from the optimum environment.

Since the upper surfaces of the circular portions 29, 31 and the connecting portion 32 are open, the water storage tank 38 and the steam tower 44 are separated from the circular portion 29 and the heating portion 36, respectively, as shown in FIG. , The insides of the circular portions 29 and 31 and the connecting portion 32 are exposed. Therefore, the circular portions 29 and 31 and the connecting portion 32 can be easily wiped. Further, as shown in FIG. 7, the frame plate 69 can be detached from the bottom plate 57 and the heater 63 can be rotated about the support portion 64 as a center axis. Can also be easily wiped.
