Abstract

Abstract An incubator apparatus for the brooding of any egg types with a closed housing. The brood is exposed to the same conditions in the entire apparatus. For this purpose an incubator apparatus is used which has a substantially rectangular or square housing compartmentalized by crosswalls into a brooding chamber and air-circulating chambers. The crosswalls divide the air channels into uniform and equal size cross sections. The air channels terminate below the lowermost brooding tray at the same distance from the bottom or at the right and left laterally next to the brooding tray. The air is warmed and circulated by fans which are provided with a heating source and which are arranged centrally on top or in the back equally spaced to the left and right from the air openings. A dust filter is arranged between the fan and the brooding chamber. The chnanels for ventilation and deaeration and the channels for humidification lead each to the suction side of the fan in the space between the dust filter and the fan and to the pressure side in the chamber. The channels are connected to a heatable water tank through which the air is enriched with moisture corresponding with the water temperature.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 391 words
In an incubator apparatus for the brooding of any egg types comprising a bottom wall, plural sidewalls and a top wall defining a closed chamber having therein means defining a brooding chamber with support means for supporting at least one brooding tray, and a door providing access to said closed chamber and said brooding chamber, the improvement wherein said means defining said brooding chamber inside said closed chamber includes plural crosswalls which also define plural air-conducting channels, said crosswalls being spaced from said walls of said closed chamber so that said air channels have uniformly sized cross sections, wherein said air channels terminate at means defining an inlet to said brooding chamber over a region below said at least one brooding tray and at an equal distance from said walls defining said closed chamber, wherein at least one fan with a heat source is provided and is arranged on a central axis of said brooding chamber equidistant from said inlet means, wherein between said at least one fan and said brooding chamber there is arranged a dust filter extending over a majority of a cross-sectional area of said brooding chamber and at a location remote from said inlet means, said air channels being connected to a pressure side of said at least one fan and receiving equal volumes of air from said at least one fan, wherein a heatable water tank is provided with two connections, first means for connecting one of said connections to said pressure side of said at least one fan and second means for connecting the other of said connections to a suction side of said at least one fan, and said second means for connecting said water tank to said suction side of said at least one fan terminating in a region between said dust filter and said at least one fan, whereby said air channels are connected to said heatable water tank so that the pressure difference between said suction side and said pressure side of said at least one fan effects a flushing of air over the surface of water in said water tank, whereby said air corresponding with the water temperature is enriched with moisture, and wherein a control of the relative humidity of said air passing through said brooding chamber is regulated by a controllable water heating system on said water tank.
Claim 2
Dependent Claim 391 words
In an incubator apparatus for the brooding of any egg types comprising a bottom wall, plural sidewalls and a top wall defining a closed chamber having therein means defining a brooding chamber with support means for supporting at least one brooding tray, and a door providing access to said closed chamber and said brooding chamber, the improvement wherein said means defining said brooding chamber inside said closed chamber includes plural crosswalls which also define plural air-conducting channels, said crosswalls being spaced from said walls of said closed chamber so that said air channels have uniformly sized cross sections, wherein said air channels terminate at means defining an inlet to said brooding chamber over a region below said at least one brooding tray and at an equal distance from said walls defining said closed chamber, wherein at least one fan with a heat source is provided and is arranged on a central axis of said brooding chamber equidistant from said inlet means, wherein between said at least one fan and said brooding chamber there is arranged a dust filter extending over a majority of a cross-sectional area of said brooding chamber and at a location remote from said inlet means, said air channels being connected to a pressure side of said at least one fan and receiving equal volumes of air from said at least one fan, wherein a heatable water tank is provided with two connections, first means for connecting one of said connections to said pressure side of said at least one fan and second means for connecting the other of said connections to a suction side of said at least one fan, and said second means for connecting said water tank to said suction side of said at least one fan terminating in a region between said dust filter and said at least one fan, whereby said air channels are connected to said heatable water tank so that the pressure difference between said suction side and said pressure side of said at least one fan effects a flushing of air over the surface of water in said water tank, whereby said air corresponding with the water temperature is enriched with moisture, and wherein a control of the relative humidity of said air passing through said brooding chamber is regulated by a controllable water heating system on said water tank.
Claim 3
Dependent Claim 41 words
The incubator apparatus according to claim 1, wherein for effecting humidification during a breakdown of said water heating system, at least one evaporator cup is arranged beneath said at least one brooding tray in said inlet means to said brooding chamber.
Claim 4
Dependent Claim 64 words
The incubator apparatus according to claim 1, wherein said at least one fan is arranged centrally above said at least one brooding tray, and wherein two equally sized and uniform air channels extend downwardly from said at least one fan to a location beneath said at least tray and said inlet means to said brooding chamber, said air traveling vertically through said brooding chamber.
Claim 5
Dependent Claim 40 words
The incubator apparatus according to claim 1, wherein said at least one fan is arranged centrally at one side of said brooding chamber and said air channels extend to an opposite side, said air traveling horizontally through said brooding chamber.
Claim 6
Dependent Claim 20 words
The incubator apparatus according to claim 1, wherein said at least one tray is equipped with a gas-permeable bottom wall.
Claim 7
Dependent Claim 19 words
The incubator apparatus according to claim 1, wherein said at least one tray has laterally upstanding walls and crosswalls.
Claim 8
Dependent Claim 15 words
The incubator apparatus according to claim 6, wherein said crosswalls consist of a transparent material.
Claim 9
Dependent Claim 23 words
The incubator apparatus according to claim 7, wherein a sidewall of said tray extending parallel to said crosswalls consist of a transparent material.
Claim 10
Dependent Claim 20 words
The incubator apparatus according to claim 1, wherein said at least one tray is equipped with a seal bottom wall.
