Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the invention and structural, methodological, or functional modifications of these embodiments that may be made by one of ordinary skill in the art are included within the scope of the invention.
It will be appreciated that terms such as "upper," "above," "lower," "below," and the like, as used herein, refer to spatially relative positions and are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The term spatially relative position may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures.
As shown in fig. 1, the present invention discloses a refrigerator 100 including a refrigerating chamber 110 and a freezing chamber 120. An ice making device 130 including an ice making tray 131 and an ice making water injection pipe 132 for supplying water to the ice making tray is provided in the freezing chamber. The refrigerator further includes a control system 140 of the ice making device. The water outlet 133 of the ice making water injection pipe 132 is arranged above the ice making tray 131 in the freezing chamber 120. The ice-making water injection pipe 132 is provided with a detection sensor 134 and a heating component 135, and the heating component 135 is arranged around the outer wall of the ice-making water injection pipe 132. The detection sensor 134 is a capacitive sensor.
In the embodiment of the present invention, a water storage container 111 is provided in the refrigerating chamber 110, and the water storage container 111 is connected to the ice-making water injection pipe 132 to supply water to the ice-making water injection pipe 132. In other embodiments, an external water source may be connected to the ice-making water injection pipe to supply water to the ice-making water injection pipe.
The ice making water injection pipe 132 is required to supply water to the ice making tray 131, and water drops may remain in the ice making water injection pipe 132 after water injection. And because the ice-making water injection pipe 132 is partially located in the freezing chamber 120, there is a possibility that the water remaining in the ice-making water injection pipe 132 may be frozen. The water injection pipe 132 for ice making after freezing can not supply water to the ice making tray 131 any more, which may result in an ice making process being impossible to continue.
In an embodiment of the present invention, the heating element 135 is a heating wire. The heating wire is wound around the outer wall of the ice making water injection pipe 132 so that the ice making water injection pipe 132 can be thawed when opened.
As shown in fig. 2 to 3, an embodiment of the present invention discloses a control method of an ice making device. As shown in fig. 1, the method includes:
in the ice making process, first detection data of a detection sensor on an ice making water injection pipe are received every a first preset time period;
judging whether water or ice exists in the ice making water injection pipe according to the first detection data;
and if water or ice exists in the ice making water injection pipe, starting the heating assembly.
In the embodiment of the present invention, the first preset time period may be 5 minutes or 10 minutes. That is, the controller receives the first detection data of the detection sensor every 5 minutes or 10 minutes during the ice making process, so as to determine whether water or ice is present in the ice making water injection pipe. Therefore, the state of the ice making water injection pipe can be timely known, and the heating assembly is started to defrost at the first time after the ice making water injection pipe is frozen.
The detection sensor 134 may be installed on the outer wall of the ice making water injection pipe 132. The detection sensor 134 is a capacitive sensor. The capacitive sensor is a type of dielectric variable capacitor that uses a change in a measured medium to cause a change in dielectric constant. Specifically, after the turning of the ice is finished and before the water injection, when the ice making water injection pipe 132 is not frozen, the inside of the pipe is in an empty state, and at the moment, the capacitive sensor can generate a dielectric constant and send a detection data to the controller to indicate that the inside of the ice making water injection pipe is free of water; when the water is left in the ice-making water injection pipe 132 or the water is frozen, the space in the pipe is filled with the ice frozen by the water, the measured medium is changed, so that the dielectric constant of the capacitive sensor is changed, and the sensor sends another detection data to the controller, which indicates that the water or the ice is left in the ice-making water injection pipe. Therefore, according to different detection data, whether the ice making water injection pipe is frozen or not can be judged. When the residual water in the ice making water injection pipe is detected, the heating component is started, so that the freezing of the ice making water injection pipe can be prevented in advance, and the possibility of subsequent freezing is reduced. The capacitive sensor has the advantages of large detection dynamic range, high response speed, simple structure and low cost.
In other embodiments, other types of sensors, such as photosensors, may also be used.
If the water or ice is in the ice-making water injection pipe 132, it indicates that the ice-making water injection pipe 132 may be frozen, and the heating unit 135 needs to be turned on to defrost the ice-making water injection pipe 132.
Further, in an embodiment of the present invention, after the step of turning on the heating assembly if water or ice is present in the ice-making water injection pipe, the method further includes:
judging whether the first heating time period is exceeded;
if the first heating time period is not exceeded, receiving second detection data of the detection sensor every second heating time period, wherein the second heating time period is smaller than the first heating time period;
judging whether water or ice exists in the ice making water injection pipe according to the second detection data;
and if the water injection pipe for making ice is anhydrous, the heating component is closed.
In an embodiment of the present invention, the first heating period is a longer period of time, for example, the first heating period may be 0.5 hours or 1 hour. Specifically, the first heating period may be preset in advance, or a plurality of times of defrosting tests of the ice making water injection pipe may be performed, so as to determine a period of time required for defrosting the ice making water injection pipe in most cases, and set the first heating period accordingly. For example, after a plurality of tests, the maximum time for which the ice-making water injection pipe is thawed is measured to be 1 hour in many cases, and the first heating time period may be set to be 1 hour.
And if the first heating time period is not exceeded, receiving second detection data of the detection sensor 134 every second heating time period. The second heating period may be a shorter period of time such as 5 seconds or 10 seconds. That is, the controller receives the second detection data of the detection sensor 134 every 5 seconds or 10 seconds within the first heating period of not more than 0.5 hours or 1 hour, so as to timely know whether to unfreeze the ice-making water injection pipe 132 in the on state of the heating assembly 135.
Similarly, if the received second detection data indicates that water or ice is present in the ice-making water injection pipe 132, it may be determined that the ice-making water injection pipe 132 is still frozen; if the second detection data received at this time indicates that there is no water in the ice-making water injection pipe 132, it may be determined that the ice-making water injection pipe 132 has been thawed under the operation of the heating assembly 135.
If the water in the ice-making water injection pipe 132 is not present, the controller may turn off the heating element 135 without continuing to turn on the heating element 135.
Therefore, by judging whether water or ice exists in the ice making water injection pipe 132 or not at intervals of a shorter second heating time period, the freezing state of the ice making water injection pipe 132 can be known in time, the heating assembly 135 is turned off after the ice making water injection pipe 132 is thawed, the thawing efficiency is improved, and the energy consumption is reduced.
Further, in an embodiment of the present invention, after the step of determining whether the first heating period is exceeded, the method further includes:
if the first heating time period is exceeded, the heating assembly is turned off;
and displaying freezing information of the ice making water injection pipe on the display panel.
In the embodiment of the present invention, since it is determined whether there is water or ice in the ice-making water injection pipe 132 every second heating period, and after detecting for a plurality of times, until the first heating period is exceeded, the heating assembly 135 is not closed, which indicates that the frozen volume of the ice-making water injection pipe 132 may be too large, the heating assembly 135 may not be sufficient to defrost the ice-making water injection pipe, and a user may need to defrost the ice-making water injection pipe using other methods, or a maintenance personnel may need to intervene. At this point the heating element 135 is not used, and thus the heating element 135 is turned off
The freezing information of the ice making water injection pipe is displayed on the display board so as to remind a user that the ice making water injection pipe is frozen, and the heating assembly cannot defrost the ice making water injection pipe, so that the ice making process cannot be normally executed, and the user is required to defrost by adopting other methods. The freezing information of the ice making water injection pipe 132 may be text, pictures, icons or other forms that may be noticeable.
Further, in an embodiment of the present invention, after the step of displaying the freezing information of the ice making water injection pipe on the display panel, the method further includes:
after a second preset time period, checking whether freezing information of the ice making water injection pipe is displayed on the display panel, wherein the second preset time period is longer than the first preset time period;
and if the freezing information of the ice making water injection pipe is not displayed on the display panel, executing the step of receiving first detection data of the detection sensor on the ice making water injection pipe every a first preset time period in the ice making process.
The second predetermined time period is a longer time period, for example, 0.5 hours or 1 hour. After the freezing information of the ice making water injection pipe is displayed, the ice making process cannot be normally performed. Therefore, after the second preset time period, the controller checks whether the freezing information of the ice making water injection pipe is still displayed on the display board. If the user thaws the ice making water injection pipe by using other methods or a maintenance person has carried out maintenance, the freezing information of the ice making water injection pipe is not displayed on the display board, and after the second preset time period passes, the controller checks the freezing information of the ice making water injection pipe which is not displayed on the display board, so that the ice making device can be controlled to normally execute the ice making program.
Further, in an embodiment of the present invention, after the step of turning off the heating assembly if the ice making water injection pipe is anhydrous, the method further comprises:
and (5) clearing a freezing mark of the ice making water injection pipe.
If the ice making water injection pipe freezing flag is set in the previous step, the ice making water injection pipe freezing flag can be cleared after judging that the water in the ice making water injection pipe is not present, so that the ice making procedure can be normally executed.
It should be noted that the freezing mark of the ice making water injection pipe is different from the freezing information of the ice making water injection pipe. The ice-making water injection pipe freeze flag indicates that the ice-making water injection pipe is in a frozen state at this time, and the ice-making water injection pipe freeze flag is cleared when the ice-making water injection pipe is thawed (e.g., thawed after the heating assembly is operated for a period of time). And the freezing mark of the ice making water injection pipe is a mark in the program, and can not be seen by a user. The freezing information of the ice making water injection pipe indicates that the ice making water injection pipe cannot be thawed after the heating assembly is operated, and a user is required to defrost by adopting other methods. And the freezing information of the ice making water injection pipe is displayed on the display panel of the refrigerator, and can be seen by a user.
Further, in an embodiment of the present invention, after the step of turning on the heating assembly if water or ice is present in the ice making water injection pipe, the method further includes:
setting a freezing mark of the ice making water injection pipe, and stopping the ice making procedure.
The heating assembly 135 needs to be turned on to indicate that the ice making water injection pipe 132 is frozen at this time, the ice making process cannot be normally performed at this time, so that a freezing flag of the ice making water injection pipe 132 is set inside the process, and the controller needs to stop the ice making process.
Further, in an embodiment of the present invention, before the step of receiving the first detection data of the detection sensor on the ice-making water injection pipe every a first preset time period in the ice-making process, the method further includes:
judging whether a freezing mark of an ice making water injection pipe is set;
and if the freezing mark of the ice making water injection pipe is not set, executing the step of receiving first detection data of the detection sensor on the ice making water injection pipe every a first preset time period in the ice making process.
If the freezing flag of the ice making water injection pipe 132 is set, it indicates that the ice making water injection pipe 132 is frozen at this time, and the ice making water injection pipe 132 cannot normally supply water to the ice making tray, and the ice making process cannot be normally performed as well.
If the freezing flag of the ice making water injection pipe 132 is not set, it indicates that the ice making water injection pipe 132 is not frozen, and water can be normally supplied to the ice making tray, and at this time, the step of receiving the first detection data of the detection sensor on the ice making water injection pipe every a first preset time period in the ice making process is continuously performed.
