Abstract
A compact low power water heater and food product warming unit especially designed for military vehicles which includes a sturdy and selectively sealed tank having uninsulated thermally conductive in which water may be heated by conduction by way of a heating element secured exteriorly of the tank. The tank is enclosed by a thermally insulated cover in such a manner that a plurality readily accessible pockets are provided between the cover and tank walls into which a plurality of field ration (MRE) or food packets may be inserted to thereby utilize the hot water in the tank as a source of heat for heating the packets.
Claims22
A combination water heater and food packet warming unit comprising, a tank in which water is selectively retained, said tank having inner and outer wall portions said inner and outer wall portions being uninsulated and made of good heat conducting material, a lid for selectively closing said tank, a heating element mounted in heat exchange relationship with said tank, control means for regulating said heating element so as to heat the water within said tank, a cover means mounted in covering relationship to the exterior surfaces of said tank, said cover means being pliable and including a heat insulating layer, at least one portion of said cover means being spaced outwardly with respect to said outer wall portions of said tank and an access opening into said at least one portion of said cover means, whereby at least one food packet may be selectively received intermediate said at least one portion of said cover means and said tank so that the contents of the food packet are heated by energy being dissipated through said outer wall portions of said tank.
A combination water heater and food packet warming unit comprising, a tank in which water is selectively retained, said tank having inner and outer wall portions, said inner and outer wall portions being uninsulated and made of good heat conducting material, a lid for selectively closing said tank, a heating element mounted in heat exchange relationship with said tank, control means for regulating said heating element so as to heat the water within said tank, a cover means mounted in covering relationship to the exterior surface of said tank, said cover means including a pliable body portion and a pliable top portion, said body portion being mounted in surrounding relationship with respect to said outer wall portions of said tank in such a manner that a plurality of the food packets may be inserted through an access means in said cover means intermediate said body portion and said tank, and said top portion being of a size to selectively cover said lid, whereby the contents of the food packets are heated by energy being dissipated through said outer wall portions of said tank.
A combination water heater and food packet warming unit comprising, a tank in which water is selectively retained, said tank having inner and outer wall portions, said inner and outer wall portions being uninsulated and made of good heat conducting material, a lid for selectively closing said tank, seal means for sealing said lid in fluid tight relationship with respect to said tank, a heating element mounted in heat exchange relationship to said tank, control means for regulating said heating element so as to heat the water within said tank, a pliable thermally insulative cover means, said thermally insulative cover means including a body portion and top portion, said body portion of said cover means being mounted in generally surrounding relationship with respect to said outer wall portions of said tank in such a manner that a plurality of the food packets may be inserted through an access opening in said cover means and retained intermediate said body portion and said tank, said top portion of said cover means being of a size to overlay said lid.
A combination water heater and food packet warming unit for use in mobile vehicles of the type having a source of electrical power supply comprising, a tank in which water is selectively retained, said tank having a bottom wall, front, rear and opposite side walls, said front, rear and side walls being uninsulated and formed of good heat conducting material, a lid for selectively closing said tank, seal means for sealing said lid in fluid tight relationship with respect to said tank, latch means for securing said lid to said tank, a heating element mounted in heat exchange relationship with respect tot said bottom wall of said tank, control means for connecting said heating element to said source of electrical energy and for regulating said heating element so as to heat the water within said tank, a thermally insulated cover means, said cover means including a body portion and a top portion both formed of a pliable material, said body portion being mounted in generally surrounding relationship with respect to said front, rear and side walls of said tank in such a manner that a plurality of the food packets may be inserted through an access means in said cover means and retained intermediate said body portion and said tank, said top of said cover means being of a size to overlay said lid and means securing said top of said cover means to said body portion when said top of said cover means is in overlaying relationship with respect to said lid whereby the food packets are selectively heated by energy being dissipated through the walls of said tank.
A combination water heater and food packet warming unit comprising, a tank in which water is selectively retained, said tank having inner and outer wall portions, said inner and outer wall portions being uninsulated and made of good heat conducting material, a lid for selectively closing said tank, a heating element mounted in heat exchange relationship to said tank, control means for regulating said heating element so as to heat the water within said tank, a cover means mounted in covering relationship to said tank, said cover means including a body portion mounted in surrounding relationship with respect to said outer wall portions of said tank, a plurality of pockets defined between said body portion of said cover means and said outer wall portions of said tank, an access opening to each of said pockets through which food packets may be inserted into said pockets so as to be retained intermediate said body portion and said tank, said cover means including a heat insulating material layer and a radiant energy reflecting layer for directing heat inwardly toward the tank, whereby contents of the food packets are heated by energy being dissipated through said outer wall portions of said tank.
