Definitions
- the present invention relates to an ice dispenser for a refrigerator as well as a flap which can be used on such an ice dispenser.
- an ice dispenser In refrigerators with built-in ice maker an ice dispenser generally comprises a guided through a housing wall, in particular the door, the refrigerator passage whose outer end is closed by a flap to prevent when not in use, hot air passes through the passage into the interior of the refrigerator. Even if the passage through the flap is closed, the ice dispenser generally represents a weak point in the insulation of the refrigerator. Therefore, its exposed on the outside of the device parts are usually colder than the ambient temperature of the device. As a result, moisture in the air condenses and forms condensation or even frost. Uncontrolled dripping sweat water is generally disturbing for the user. If the donor is constantly moist due to the condensation, this promotes the growth of bacteria, and odor and hygiene problems can occur. If frost is deposited directly on an edge of the discharge opening that is touched by the flap, the flap may freeze so that ice can no longer be dispensed.
- Such a heater may be stationarily located adjacent to the dispensing opening or movably on the flap.
- a stationary heater is known, for example, from US Pat. Nos. 3,640,088 and 5,442,933. If such a heater is disposed between a fixed outer skin of the refrigerator housing and a Isolierschaum Mrs behind it, the distance of the heater from the edge of the discharge opening is quite large, and a high heating power is required to prevent freezing. This heat output affects the energy efficiency of the device. In addition, in case of failure of the heater repair is hardly possible economically.
- a heater attached to the outside of the skin may be placed closer to the edge of the dispensing opening, such heating is generally visible or touchable to the user, which is undesirable or even dangerous.
- a heater behind conceal a cover but this in turn requires a higher heat output.
- US 5 269 154 A discloses an ice dispenser in which the flap is provided with a heater.
- the heater is designed as a foil heater, which is inserted between a fixed outer wall of the shell and the output opening facing insulation layer.
- foil heater is able to prevent condensation on the outside of the flap, but it is because it is separated from the edge of the discharge opening by the insulating layer, poorly suited to prevent freezing of the flap.
- Object of the present invention is to provide an ice dispenser or a flap for that are simple and inexpensive to implement and reliably prevent condensation.
- the heating loop at its ends is preferably integrally connected to two of the outside of the flap adjacent heating conductors.
- the heating receiving channels are preformed on a filled with insulating material carrier body of the flap.
- the carrier body may be a shell which is open toward the inside of the flap, so that the insulating material accommodated in the shell faces the discharge opening.
- a channel receiving the heating loop expediently runs on one edge of the shell, whereas a channel receiving the heating conductor preferably runs on a bottom of the shell.
- the assembly of the flap is particularly simple when a heating loop receiving channel is open to the periphery of the flap.
- a heating conductor receiving channel is preferably open to the outside of the flap. On the one hand, this makes the laying of the heating conductors easy; on the other hand, the heat output from the heating conductors to the insulating material is lower than in the case of a channel open towards the inside of the flap.
- the heating conductor receiving channel preferably forms a closed loop and a branch crossing the loop.
- Subject of the invention is also a flap for an ice dispenser, in particular for an ice dispenser of the type defined above, which has a carrier body in the form of a shell, in the shell recorded insulation material and a heater, wherein the heater has a running at one edge of the shell heating loop and on the ground the shell extending heating conductor comprises.
