Detailed Description
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, and the present invention is not limited to or by the embodiments.
Fig. l is a front perspective view for explaining the present invention, fig. 2 is a partially enlarged front view for explaining a heat exchanging part and a circulation fan of fig. 1, fig. 3 is a plan sectional view of fig. 1, fig. 4 is a partially enlarged sectional view for explaining a heat exchanging part of the heat exchanging part of fig. 3, and fig. 5 is a plan sectional view for explaining a use state of the present invention.
As shown in the drawing, a conventional incubator is used as a device for artificially incubating fertilized eggs, and most of the fertilized eggs are incubated in a small amount, so that the incubation efficiency is reduced.
Accordingly, a large hatching facility has been used, and in such a conventional large hatching facility, along with the need for a mechanical room for adjusting the internal temperature and the need for various equipments, that is, additional facilities such as a boiler, a water tank, a pump, an air conditioner, various pipeline lines, and a wire, a lot of capital costs are required, and maintenance and repair have various difficulties along with the limitation of installation area conditions.
In particular, the most significant drawback of the conventional mass hatching facilities is that the circulation of the heat-exchanged air is not smooth due to the plurality of trays stored therein, thereby reducing the hatching effectiveness.
The present invention can adjust the temperature in the incubator by using the thermoelectric element, so that the mechanical room for adjusting the temperature in the conventional large-scale incubation device does not need air conditioning facility and the like together with various devices, and the heat-exchanged air can be uniformly and uniformly circulated in a large number of trays.
The incubator 1 of the present invention comprises: the container 10 is provided with a receiving space 12 for arranging a plurality of normal trays T, a plurality of fertilized eggs to be hatched are placed on the plurality of trays T in a multi-layer manner, and four sides of the container 10 are closed, so that a normal control display panel 14 and at least one opening and closing door 16 for operation are formed in the front of the container 10. At least one normal temperature sensor (not shown) connected to the control display panel is disposed in the container at a predetermined interval, so that the temperature of each position in the container can be accurately detected. The control display panel is provided with not only a plurality of normal operation buttons but also a known control unit for controlling set values of various devices, together with the display panel and the like.
The container 10 is manufactured using a general assembly panel, and can be manufactured in a desired size or volume according to installation conditions or an area.
Therefore, the convenience that the manager can accurately and simply grasp the internal state of the container through the control display panel is provided.
A general exhaust fan 20 and a damper 20A are provided on the upper surface of the container 10 so as to exhaust the internal air or to allow the external air to flow in according to the temperature inside the container 10. The exhaust fan and the door serve to exhaust the inside air or suck the outside air according to the inside temperature of the container by being connected to the control display panel.
Further, the heat exchanger 30 is provided, the heat exchanger 30 is composed of a plurality of heat exchange members 35, and a known thermoelectric element 32 is disposed on both sides of the rear surface of the container 10 on the opposite side of the opening/closing door 16 with a predetermined interval therebetween, so that the internal temperature of the container 10 can be adjusted. The heat exchange unit is also connected to the control display panel to operate in a heating or cooling manner according to a set value.
That is, the heat exchange member of the heat exchange unit is heated or cooled by the thermoelectric element according to a set value by the temperature sensor provided inside the container and the control unit controlling the display panel, thereby maintaining the temperature inside the container at an optimum and appropriate condition. Although described in the subsequent sections, the above-described heat exchange member has a technical structure including a thermoelectric element, and heating and cooling are achieved due to the characteristics of the thermoelectric element, thereby providing a minimally simple structure.
This makes it possible to eliminate the need for various auxiliary facilities in conventional hatching facilities.
In other words, heating and cooling are achieved due to the thermoelectric element, so that not only a machine room, various equipments, i.e., a boiler, a water tank, a pump, an air conditioner, various pipeline lines, which have been used for temperature adjustment in a large number of hatching apparatuses in the past, can have conditions of subsidiary facilities without wires, etc.
Therefore, the device has the advantages of not only not needing to invest expenses for facilities, but also being not limited by the conditions of the set area, and being capable of simply and conveniently carrying out maintenance and repair.
In addition, circulation fans 40 are provided in front of the heat exchange members 35 of the heat exchange units 30, and the circulation fans 40 circulate air heat-exchanged by the heat exchange members 35. The circulation fans 40 are directly connected to a driving member 42 such as a normal motor provided on the outer side of the rear surface of the container 10 to rotate in opposite directions. The blades of the circulation fan have a common technical structure and are consonant in KoreanThe width of the zigzag form is narrower toward the outside from the center connected to the driving member. Thus, when the circulation fan rotates, the air flows in a radial manner in the outside direction. As a result, as shown in fig. 5, the heat-exchanged air rotates along the inner wall of the container in the rotation direction, and a dead zone (dead zone) due to the air flow is generated between the circulation fan and the circulation fan, thereby providing a condition of uniformly and uniformly circulating the air.
In particular, the plurality of heat exchange members 35 provided in the heat exchange portions 30 are arranged within a range not departing from the outer diameter of the circulation fans 40 provided in front of the heat exchange members 35.
In other words, the circulation fan 40 is provided in front of the heat exchange member 35 so as to have a condition for effectively circulating the entire air heat-exchanged in the heat exchange member 35. When the heat exchange member is separated from the outer diameter of the circulation fan, heated air may rise upward due to the characteristics, and cooled air may sink, so that the heat exchange member is not separated from the outer diameter of the circulation fan, and the entire air heat-exchanged in the heat exchange member may be uniformly circulated forward.
On the other hand, the heat exchange member 35 includes, in order: an inner heat dissipation plate 33 of a normal form, in which a plurality of normal heat dissipation pins 33A located inside the container 10 are formed at predetermined intervals; a transfer block 34 made of aluminum or the like having excellent conductivity and configured to transfer hot air or cold air to the rear surface of the inner heat sink 33; a known thermoelectric element 32 provided on the back surface of the transmission block 34 so as to be connected to the control display panel; an outer heat radiation plate 36 formed with a plurality of normal heat radiation pins 36A provided on the back surface of the thermoelectric element 32 to the outside of the container 10 at predetermined intervals; and a normal cooling fan 38 located on the back surface of the outer heat sink 36. The transfer block is used for compensating the thickness of the back surface of the container, and can be formed in various thicknesses according to the thickness of the container.
In other words, when the thermoelectric element is used for heating or cooling, hot air or cold air is transferred to the inner heat dissipation plate through the transfer block, and the transferred hot air or cold air is supplied to circulate the inside of the container by the circulation fan located in front of the inner heat dissipation plate.
In addition, since the outer heat dissipating plate located outside the container is not able to smoothly control the temperature inside the container when it is not rapidly released due to the generation of cold air or hot air opposite to the hot air or cold air supplied to the inside of the container, the cold air or hot air passing through the outer heat dissipating plate is rapidly released into the atmosphere by the cooling fan.
This provides conditions under which the internal temperature of the container can be controlled more precisely and accurately.
The inner heat sink 33 is formed to have a wider area than the outer heat sink 36 so as to improve heat exchange efficiency, and the interval between the heat dissipation pins 33A formed in the inner heat sink 33 is approximately 5 to l0 mm. The heat dissipation pins formed on the outer heat dissipation plate have a normal interval of 2-3 mm. This does not cause any hindrance to heat dissipation, but when the container is set inside, if foreign matter, particularly fertilized eggs, generated inside the container hatch, hairs or the like are sandwiched between the heat dissipation pins to lower the heat dissipation performance. Further, when the hairs or the like are sandwiched and removed, there is a disadvantage that the heat dissipation pins are too narrow to be easily pulled out at the time of high-pressure cleaning.
Accordingly, it is preferable that the heat radiation pins of the heat radiation plate located inside the container have a space between which foreign matters or feathers are not easily caught or which can be easily separated during high-pressure cleaning even if some of the foreign matters or feathers are caught.
However, when the thickness is 5mm or less, a phenomenon such as a heat radiation pin of the outer heat radiation plate frequently occurs, and when the thickness is l0mm or more, although the cleaning efficiency is excellent, there is a disadvantage that the heat radiation efficiency is lowered. Thus, the above-mentioned interval of approximately 5 to 10mm is appropriate.
Thus, in the present invention, since a general thermoelectric element is used as a structure for incubating a large number of fertilized eggs, not only a mechanical room for temperature adjustment in a conventional large-scale incubation apparatus, but also various apparatuses, i.e., a boiler, a water tank, a pump, an air conditioner, and various pipeline lines can have conditions that do not require additional facilities such as wires.
Therefore, the system also has the condition of simple and convenient maintenance without large investment of facilities and limitation of the installation area condition.
Further, the incubator of the present invention can be manufactured in various sizes or volumes according to installation conditions, thereby providing convenience in simple installation without any place or installation condition.
