Definitions

  • the present invention relates to a satchel in which heat o1 cold can be generated by means of a so-called Peltier battery, i.e., a battery operating on the principle of the Peltier eflect, which relates so the production or absorption of heat at the juncture of two metals on the passage of a current. Heat generated by the passage of current in one direction will be absorbed if the current is reversed.
  • Peltier battery i.e., a battery operating on the principle of the Peltier eflect
  • the present invention resides, mainly, in a Peltier-type heating and cooling satchel which is connectible eo a powerpack or to a current mains, z1nd which comprises means forrning an insulated housing, there being arranged at the upper half of the housing a Peltier battery which incorporates a plurality of Peltier elements, each having a first contact region which changes its temperature in one direction when a direct current flows through and a second contact region which changes its temperature in the other direction when this direct current flows.
  • the one region of each Peltier element is directed toward the interior of the housing and the second contact reglon of each Peltier element is directed toward the outside of the housing.
  • the satchel includes an ice cube tray which is made of a material that is a good conductor of heat, this ice cube tray being provided With partitions and With external ribs, and being in contact With the first comtact regions of the Peltier elements.
  • a container also made of a materlal which 1s a good conductor of heat, is provided, this container being adapted to receive a sub stance to be heated and being placeable over the ice cube tray including the external Iibs thereof.
  • a ventilator serves to enhance the heat exchange between the grid and the ambient atmosphere.
  • FIGURE 1 is a vertical section of a satchel according to the present invention.
  • FIGURE 2 is a side elevational view, partly in section, of the satchel of FIGURE l.
  • FIGURE 3 is a plan view, partly in section, of the satchel of FIGURES 1 and 2.
  • FIGURE 4 is a plan view, partly in section and 011 an enlarged scale, showing the structure of the ice cube tray.
  • FIGURE 5 is a circuit diagrarn of a satchel according to the present invention.
  • FIGURE 1 shows the satchel as having a housing a made of a plastic material having good insulating characteristics. Also shown is a Peltier battery b, at whose right side-i.e. the side whlch, in FIGURE l, is shown as being directed toward the interior of the satchelis arranged a metal container c, there being two smaller metal, internallypositioned, ice cube tray type containers d, arranged above and below the container c, for producing ice cubes. The lower one of the ice cube trays d is mounted for movement to and f1'0 along a suspension-track type rai1 e.
  • a cover u which is likewise made of a material having good heat insulating characteristics. Also shown, schematically, is a small ventilator g as well as a plug board h and an immersion heater f.
  • FIGURE 2 shows the satchel as including a small fractional horse power motor l, a small rotary pump m driven by motor l, a water reservoir n, a relay 0 for automatical- 1y switcning the Peltier battery b 011 and 01T, a. four-pole pull-type connector p, a four-pole switch q which may be fashioned as a push Button type switch or as a rotary switch for operating the satchel, and a control 1amp r for indicating -as to whether the satchel is switched on.
  • the satchel further includes a bin1etallic switch s which is set so as automatically to tun-1 off the current when a temperature cf, for exan1ple, between 65 and 70 C. is reached.
  • the heat exohange surface of tl1e container in contact With the contact regions of the elements of the Peltier battery b is shown at t.
  • FIGURE 3 shows the i-ce cube tray d, as wel1 as the heat exchange surfaces of the container c.
  • FIGURE 3 also shows the heat exchange grid k, including the coolant coils v for carrying off heat fron1 tl1e grid k.
  • the reference cl1ara cters a, l, m, n, o, identify the same parts as1n FIGURES 1 and 2.
  • FIGURE 4 shows the ice cube tray d, 011 an enlarged scale, this tray d having been shifted into engagement With the heat exchange surfaoe of the larger container c in Which, with the current flowing in the proper direction, a liquid, as for example, a baby bottle oontaining milk, juice 01' a formula, can be heated up to the desired temperature.
  • a liquid as for example, a baby bottle oontaining milk, juice 01' a formula

  • E stands for freezlng
  • K for c-ooling
  • W heatlng.
  • the satchel can be operated either by being connected to a battery or 10 a current ma1'ns, such as house current.
  • the Peltier battery can be arranged at the upper half f one -side Wall, or in the cover for the satchel, this Peltier battery itself being composed of a number of Peltier elements. As described above, the battery is so arranged that those contact regions of the Peltier elements which change their temperature in one dinection when a direct -current flow through are directed toward the inside of the satchel while those contact regions of the Peltier elements which change their temperature in the other directi-on are directed toward the outside, i.e., the ambient space.
  • a ventilator or blower driven by a small fractional horse power motor, for enhancing the heat exchange between the grid and the ambient atmosphere.
  • the arrangement of the arts is such that the interior of the satchel is heat insulated from the other side of the Peltier battery, i.e., the contact regions of the Peltier elements which are heated up, so as to make sure that the interior of the satchel will absorb as little heat as possible -from the Peltier elements.
  • the bimetallic switc-h shuts off the currents when the desired temperature has been reac'hed, e.g., the temperature at which ice is formed in the ice cube container.
  • the desired temperature e.g., the temperature at which ice is formed in the ice cube container.
  • a switching arrangement which allows the ice cube tray to be removed from the contact regions of the Peltier elements after the eurrent has been interrupted, and to place an insulating layer between the ice cube tray and this contact region. In this way, heat is prevented from being returned from the Peltier elements to the ice cube tray.
  • the automatic switch is also suited to shut ofi the cm- 1ent when the satchel is used for heating, this being effected by changing the polarity of the current fed to the Peltie1 elements by means of the change-over switch.
  • the individual ice tray compartments can be made to have a conical configuration, and thin rods w can be made to dip into the spaces Within which the ice cubes are formed. These rods can be used to remove the ice cubes from the ice tray.
  • the satchel according t-o the present invention can be used in conjunction with an immersion heater, by means of which the temperature can be raised above that which can be reached by the Peltier elements.
  • the immersion heater too, can be operated from a current mains or from a portable power pa-ck.
  • the second ice cube tray can be mechanically or magneti cally c-ou-pled to the inwardly directed contact regions of the Peltier battery.
  • a Peltier-type heating and cooling satchel connectible to a power-pack or to a current mains and comprising, in cornbination:
  • a Peltier battery arranged at the upper half of said housing, said battery incorporating a plurality of Peltier elements, each having a first contact region which changes its temperature in one direction when a direct current flows through and a second contact region which changes its temperature in the other direction when said direct current flows, said one region of each Peltier element being directed toward the interior of said housing and said contact region of each Peltier element being directed toward the outside of said housing;
  • an ice cube tray made of a material which is a good conductor of heat, said ice cube tray being provided With partitions and with external ribs, said ice cube tray being arranged in said housing and in contact with said first contact regions of said Peltier elements;
