Embodiment Construction

[0029] figure 2 The structure inside the casing 20 used for pouring ice in the ice maker of the present invention is given in detail in . In addition, in the present invention, the structure of the ice maker will also be described with reference to FIG. 1 .

[0030] The heater 15 in the present invention is only used when the ice maker performs an ice-empty action. In addition, the on / off control process of the heater 15 in the present invention will be described together with the mechanical structure of the ice pouring action.

[0031] The motor is a device that provides rotational force for the rotation of the ice pushing rod 14 in order to realize the ice pouring action. In addition, the motor also provides rotational force to the cam 36 for sensing whether the ice cubes are full. That is, the above-mentioned motor 30 is a device for generating power required by the ice maker.

[0032] As shown, the present invention utilizes sensors and magnets for sensing the positio...

Abstract

A heater control device and method for a special ice maker for a refrigerator. The upper and lower parts of the ice making container are respectively equipped with an ice pushing rod and a heater; first and second magnets; sensors for sensing the first and second magnets; , 2 The magnet is installed at one end of the power transmission part. The control method of the heater is to drive the heater driving stage to separate the ice from the ice-making container to generate heat when the ice making is completed; to provide power to the ice push rod to rotate; through the sensor to detect The stage of the first and second magnets; the stage of stopping the drive of the heater when the second magnet is detected; the stage of performing the ice pouring operation until the first magnet is detected again by the sensor after the heater is stopped; The phase in which power is supplied to the ejector to rotate it begins after a predetermined time has elapsed after the heater has been actuated. It uses a physical method to sense the time point when ice cubes fall off from the ice maker, and can effectively control the action of the heater.

Description

technical field [0001] The invention relates to a heater control device and method for a special ice maker for a refrigerator. Background technique [0002] The structure of the ice maker of the prior art is as Figure 1a with Figure 1b As shown, the structure of a general ice maker will be described below with reference to this figure. [0003] The ice maker as shown in the figure is fixed to the rear wall of the freezer by connecting brackets 2a, 2b extending from the top of the ice-making container 12, for example, using the small holes on the connecting brackets 2a, 2b to pass Attachment screws are secured to the rear wall of the freezer. [0004] The ice making container 12 in the ice maker is a container for injecting water into it to make ice cubes of a certain shape in order to make ice. The water in the ice making container 12 is injected through the water supply pipe on one side of the ice making container. [0005] On the top of the above-mentioned ice making...
