Description

[Detailed Description of the Invention] The present invention relates to a new and simple electric incubator for artificially hatching fertile eggs such as chicken eggs.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a hollow mount having an approximately truncated conical shape with an upward step 2 formed on its outer peripheral surface, and a wall 4 surrounding it at the periphery of its upper end surface. At the same time, a suitable part of this wall is cut out to form a water droplet flow groove 5 which is continuous with the peripheral surface of the mounting base. Reference numeral 6 indicates an intake port provided between the flow grooves 5 on this mounting base, and 7 indicates an intake port provided on the mounting base 1.
This is a vertically elongated slit-shaped exhaust port provided on the circumferential surface of the mounting base above the stepped portion 2, and this is provided on the remaining circumferential surface except for a part of the circumferential surface of the mounting base, as shown in Fig. 3. . Reference numeral 8 denotes an annular lower case having a substantially U-shaped cross section, which is fitted onto the mounting base 1 from above, and is attached to the inner wall 9.
It is fixed in the placed state by engaging the hooks 10 provided at three locations on the upper end of the board into the through holes 11 provided in the stepped portion 2. The lower case 8 has an inner diameter such that a predetermined gap is formed therebetween when placed on the mounting base 1, and is configured such that the upper end of the inner wall 9 is located at a lower position than the stepped portion 2. Ru. Reference numeral 12 denotes a plurality of vertical ribs formed on the inner surface of the outer wall 9' of the lower case 8, 13 the water injection part formed by bulging the upper end of the outer wall 9' outward, and 14 covering the upper opening of the lower case 8. For example, the upper case is transparent, and together with the lower case 8, it is formed into a spherical shape as a whole. 15 is a plurality of exhaust holes provided in the ceiling of the upper case; 16 is a lid rotatably attached to the upper case 14 with a push nut 17 in order to adjust the opening degree of the exhaust holes; have Reference numeral 19 denotes an annular egg holder which is fitted into the mounting base 1 from above and whose peripheral edge is supported by the upper end of the rib 12, which has an outer diameter smaller than the inner diameter of the lower case and has a large number of through holes; Further, on the upper surface, there are a plurality of recesses 20 for holding the eggs in a stable state.
has been established. Reference numerals 21 and 21 refer to cushioning materials attached to the inner and outer peripheral edges of this egg placement plate, and 22 refers to the mounting base 1.
A motor 23 and a temperature control circuit board 24 are attached to a mounting board fixed to the lower surface of the stepped portion 2 in the hollow interior. 25 is a fan fixed to the motor 23 corresponding to the exhaust port 7; 26 is an electric heater disposed inside and above the mounting base 1; and is fixed to the substrate 22 by a support 27. Reference numeral 28 denotes a temperature sensor consisting of a thermistor fixed to the support column 27, facing the intake port 6. Thus, the support column 27 is extended and fixed to the substrate 22 in a portion where the exhaust port 7 is not formed. 29 is a steam regulating plate inserted and supported inside the lower case 8 with the rib 12 as a guide, and a steam port 30 for properly steaming.
has. 31 is a bottom plate of the mounting base 1, which is screwed together with the supporting legs 32 to the mounting base.

In the above configuration, the lower case 8 is fitted and placed on the step part 2 of the mounting base 1 in advance, and the rib 1
An egg placing plate 19 is supported on top of the egg placing plate 19, and after the eggs are placed in the recesses 20 of the egg placing plate 19, the upper case 14 is covered. After that, the heater 26 is energized and the fan 2 is turned on.
5, the air sucked into the mounting base 1 from the intake port 6 is heated by the heater 26 and is blown out from the discharge port 7 as warm air.
Therefore, an air flow is formed inside the upper and lower cases as shown in FIG. The temperature is maintained at a constant temperature of approximately 37°C by the heating system to warm the eggs. In such an atmosphere, chickens can be hatched in 21 days, canaries in 14 days, and quails in 17 days, the same number of days they would hatch naturally. Therefore, if the upper case 14 is made of a transparent material in advance, the inside can be directly observed from the outside, which can be useful for children's natural science studies, for example. Although appropriate humidity is essential for hatching, if you want to replenish water to the lower case 8 during the hatching process, you can do so from the water inlet 13 without having to take the trouble of removing the upper case 14. Since the water overflows from the upper end of the inner wall 9 and flows out through the gap with the mount 1, the electrical components inside the mount will not be splashed with water, thereby ensuring safety. On the other hand, the humidity inside the case can be arbitrarily adjusted by changing the degree of opening of the exhaust hole 15 provided in the ceiling of the upper case 14 by rotating the lid 16.

As described above, according to the present invention, there is provided a cylindrical mounting base that houses a fan and a heater inside, and is provided with an intake port and an exhaust port at the upper and lower parts, and An annular lower case with a generally U-shaped cross section that opens upward and surrounds the rim and fits onto the peripheral surface of the mounting base, and is supported on the outer periphery of the lower case and covers the upper part of the intake port on the upper part of the mounting base. It is equipped with an upper case provided with an upper case, and a ring-shaped egg holder supported inside the lower case, and an intake port is opened on the circumferential surface of the closed top of the mount, and the inside of the mount is A fan is disposed at a position below the heater facing the exhaust port to form a circulation air passage that communicates the inside and outside of the mount, and a predetermined flow of passing air is provided at a position above the heater inside the mount. A temperature sensor is provided to detect the temperature of the air flow in order to maintain the same temperature, and the temperature sensor is placed on the upstream side of the mounting path in the circulation air passage where the influence of the heater is least, so that the temperature of the hot air can be accurately captured. This has the effect of eliminating temperature unevenness within the case and improving hatching efficiency.
