Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electric incubator for artificially incubating fertile eggs, for example, of birds.A substantially spherical hatching chamber is constructed by hemispherical upper and lower cases, and the temperature in the hatching chamber is It maintains an even and constant temperature and allows the eggs to hatch.

One embodiment of the present invention will be described below.1
is a mounting base that has a generally stepped cylindrical shape and has an intake port 2 on the upper periphery and an exhaust port 4 with a grid 3 formed on the lower periphery, and has grooves 5 and vertical walls 6 at four locations on the top surface of the cylinder. has been established. Reference numeral 7 denotes a hemispherical lower case that is fitted and mounted on the mounting base 1 so as to surround the exhaust port 4, and has a water inlet 8 formed on the opposite surface of the upper opening edge, and ribs 9 at four places on the inner surface. It is installed in one piece.
Further, there is a cylindrical shape rising from the lower part, and hooks 10 are provided at three places on the circumferential part 34, and by fitting into the square hole 11 of the mounting base 1, the hook 10 can be removably hung. It's on. Reference numeral 12 is an egg holder consisting of a cushion material 13 attached to the outer and inner edges, a large number of small holes 12a of several millimeters in size throughout, and a recess 14 for placing eggs in the center surface. be. Reference numeral 15 denotes a hemispherical upper case supported on the outer periphery of the lower case 7, and having an exhaust adjustment cap 16 rotatably attached to the upper part with a push nut 17. The upper case 15 and the cap 16 are provided with exhaust ports 18 and 19 at opposing positions, respectively. Reference numeral 20 denotes a support to which a substrate 22 to which a heater 21 and a temperature sensor 23 are attached is attached with screws. 24 is a fan, which is directly connected to a motor 26 attached to a base 25. Further, reference numeral 27 denotes a control board comprising an electric circuit for controlling the temperature detected by the temperature sensor 23, and is fixed to a mounting plate 28 extending downward from the base 25.

29 is a bottom plate, which is screwed to the mounting base 1 together with the legs 30. 31 is lower case 7 and upper case 1
5 and an evaporation regulating plate provided with evaporation ports 32 as appropriate so that water entering the lower part of the lower case 7 can properly evaporate in order to properly maintain the temperature inside the hatching chamber 35, which has a substantially spherical configuration. It is. Further, the height of the cylindrical portion 34 of the lower case 7 is lowered relative to the step portion 33 of the mounting base 1, and the height of the cylindrical portion 34 of the lower case 7 is
There is a gap between them.

In the embodiment of the present invention configured as described above, when the egg A is placed in the recess 14 of the egg holder 12 placed on the rib 9 of the lower case 7, the heater 21 is energized, and the fan 24 is rotated, As shown in FIG. 1, the air sucked in from the air inlet 2 around the cylindrical upper part of the mounting base 1 is heated, and is blown out as warm air from the air outlet 4 in the direction of the arrow along the inner wall surface of the hemispherical lower case 7. A part of the warm air passes between the outer peripheral edge of the egg holder 12 and the inner wall surface of the upper case 15, and the other warm air passes through the many holes 12a of the egg holder 12 and enters the hatching chamber 35. After flowing into the upper part and warming the eggs A, the cycle starts again where the eggs are sucked in through the intake port 2 of the mounting base 1, and the inside of the hatching chamber 35 is maintained at a constant temperature of about 37°C. Also, at this time, the warm air warms the water placed in the lower part of the lower case 7 to keep the humidity in the hatching chamber 35 at an appropriate level. Replenish this water in upper case 15.
Do this from the water inlet 8 of the lower case 7 while it is open.
In the unlikely event that too much water is added, it will overflow from the cylindrical portion 34 and flow out of the lower case 7 without splashing water onto the electrical components installed in the mounting base 1, thereby ensuring safety.

On the other hand, the humidity in the hatching chamber 35 can be adjusted by adjusting the opening degree of the exhaust port 18 of the cap 16 provided at the top of the upper case 15.

As described above, according to the present invention, warm air is circulated along the inner wall surface of the hatching chamber, which is formed into a substantially spherical shape by the hemispherical upper and lower cases, so that the heat exchange rate of the warm air is good, and the outside air Since the influence of heat can be suppressed as much as possible, the temperature distribution inside the hatching chamber is good and stable temperature control can be achieved. In addition, all electrical components such as the heater, temperature sensor, fan, motor, and control board are mounted on the base and placed in a cylindrical mounting base, saving space and simply removing the pace. Since all electrical parts can be taken out, maintenance and inspection are easy.
