Abstract

An ice machine, a fault handling method and fault handling apparatus of the ice machine, and a refrigeration device. The ice machine includes an ice machine body, an ice making tray located in the ice machine body, a heating assembly, and an ice stirring assembly for stirring out ice made in the ice making tray. A fault of an ice stirring assembly is automatically removed by means of a heating treatment mode of gradually raising a heating temperature multiple times, the method and apparatus moving simply and quickly, wherein the satisfaction degree of users is improved.

First claim

What is claimed is:

1. A fault handling method for an ice machine, the ice machine including an ice making tray and ice storing bin, the method comprising:
detecting and determining that a fault occurs in an ice pulling-out component of the ice machine;
detecting that a switch of the ice storage bin has not been dislocated for more than a preset manual handling time period; and
controlling a heating component of the ice machine to heat based on one or more of a plurality of preset target temperatures that increase among one another in response to detecting the fault occurring in the ice pulling-out component and the switch of the ice storage bin not having been dislocated for more than the preset manual handling time period.

2. The fault handling method according to claim 1 , wherein the detecting and determining that a fault occurs in the ice pulling-out component comprises:
controlling an ice pulling-out operation of the ice pulling-out component and collecting a reset signal of the ice pulling-out component;
analyzing the reset signal to determine that the ice pulling-out component is not reset to an equilibrium position; and
determining that the ice pulling-out component is stuck by ices.

3. The fault handling method according to claim 1 , wherein detecting and determining that a fault occurs in the ice pulling-out component comprises:
controlling the ice pulling-out component to execute an ice pulling-out operation according to an ice pulling-out control signal; and
determining that the ice pulling-out component is frozen when the ice pulling-out action fails.

4. The fault handling method according to claim 1 , wherein controlling the heating component to heat based on the one or more preset target temperatures comprises:
controlling the heating component to heat for a first preset time period based on a first preset target temperature of the one or more present target temperatures that is higher than an ice detaching temperature;
controlling the heating component to heat for a second preset time period based on a second preset target temperature of the one or more present target temperatures that is higher than the first preset target temperature; and
controlling the heating component to heat based on preset target temperatures that increase over one another until the heating component is controlled to heat based on a third preset target temperature of the plurality of present target temperatures.

5. The fault handling method according to claim 4 , wherein the third preset target temperature is 105° C.

6. The fault handling method according to claim 4 , further comprising:
controlling the heating component to heat based on the third preset target temperature for a third preset time period, and acquiring a temperature in an ice making tray of the ice machine; and
controlling the heating component to stop heating when the temperature in the ice making tray reaches a preset evaporating temperature.

7. The fault handling method according to claim 6 , further comprising:
controlling the heating component to continue heating based on the third preset target temperature when the temperature in the ice making tray is lower than the preset evaporating temperature.

8. A device, comprising:
at least one processor;
a memory; and
at least one program stored on the memory and implementing that, when executed by the at least one processor, executes acts including:
detecting and determining that a fault occurs in an ice pulling-out component of an ice machine;
detecting that a switch of the ice storage bin has not been dislocated for more than a preset manual handling time period; and
controlling a heating component of the ice machine to heat based on one or more of a plurality of preset target temperatures that increase among one another in response to detecting the fault occurring in the ice pulling-out component and the switch of the ice storage bin not having been dislocated for more than the preset manual handling, time period.

9. An ice machine comprising a fault handling apparatus, an ice pulling-out component, an ice making tray, an ice storing bin, and a heating component, the fault handling apparatus including a processor and a memory, the memory having executable instruction stored thereon, which when processed by the processor, enable the processor to implement actions including:
a first detecting action that detects and determines that a fault occurs in the ice pulling-out component; and
a second detecting action that detects that a switch of the ice storage bin has not been dislocated for more than a preset manual handling time period; and
a controlling action that controls the heating component to heat based on one or more of a plurality of preset target temperatures that increase among one another in response to detecting the fault occurring in the ice pulling-out component and the switch of the ice storage bin not having been dislocated for more than the preset manual handling time period.

10. The ice machine according to claim 9 , wherein the first detecting action comprises:
a collecting sub-action that collects a reset signal of the ice pulling-out component after the ice pulling-out component completes an ice pulling-out operation; and
a determining sub-action that analyzes the reset signal to determine that the ice pulling-out component is not reset to an equilibrium position, and to determine that the ice pulling-out component is stuck by ice.

11. The ice machine according to claim 9 , wherein the controlling action controls the ice pulling-out component to execute an ice pulling-out operation according to an ice pulling-out control signal; and
the first detecting action comprises:
a detecting sub-action that detects the ice pulling-out action signal for the ice pulling-out component; and

a determining sub-action that determines that the ice pulling-out operation fails according to the ice pulling-out action signal and to determine that the ice pulling-out component is frozen.

12. The ice machine according to claim 9 , wherein the controlling action:
controls the heating component to heat for a first preset time period based on a first preset target temperature of the plurality of preset target temperatures that is higher than an ice detaching temperature;
controls the heating component to heat for a second preset time period based on a second preset target temperature of the plurality of preset target temperatures that is higher than the first preset target temperature; and
controls the heating component to heat based on preset target temperatures that increase from one another until the heating component is controlled to heat based on a third preset target temperature of the plurality of preset target temperatures.

13. The ice machine according to claim 12 , wherein the third preset target temperature is 105° C.

14. The ice machine according to claim 12 , wherein the fault handling action includes acquiring a temperature in the ice making tray after the controlling action controls the heating component to heat based on the third preset target temperature for a third preset time period; and
