Abstract

The invention relates to the technical field of intelligent household appliances, and discloses a method for controlling a refrigerator, which comprises the following steps: detecting the temperature of a water injection pipe before water injection to obtain a first temperature; detecting the temperature of the water injection pipe after water injection to obtain a second temperature; analyzing the ice blockage condition of the water injection pipe according to the first temperature and the second temperature; and under the condition of ice blockage of the water injection pipe, the water injection pipe is controlled to be heated for ice melting. As the duration of the water injection process is short, the difference value between the second temperature and the first temperature can reflect whether water stays in the water injection pipe or not. Therefore, whether the water injection pipe is subjected to ice blockage can be judged, and the ice blockage condition of the water injection pipe can be judged more accurately. Therefore, ice melting can be conducted on the water injection pipe only under the condition that the water injection pipe is blocked by ice, and compared with the prior art that the water injection pipe is heated before water injection every time, energy consumption is lower. The invention further discloses a device for controlling the refrigerator, the refrigerator and a computer readable storage medium.

Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method and device for controlling a refrigerator, a refrigerator, and a computer-readable storage medium. Background Art

[0002] The working environment of the ice maker in the refrigerator is usually filled with cold air and has a low temperature. When the ice maker is not running, the temperature of the water injection pipe is low. During the water injection process, the water used for ice making is easy to freeze in the water injection pipe, causing ice blockage.

[0003] In order to reduce ice blockage in the water injection pipe, the related art discloses a control method for a refrigerator. The method heats the water injection pipe for a first preset time before ice making, which can reduce the possibility of ice blockage. When the temperature difference of the water injection pipe is less than or equal to the preset difference within a period of time before and after the water pump is started, and the current water temperature is less than or equal to the preset water temperature threshold, the water supply system stops working. The method can reduce the possibility of ice blockage in the water injection pipe in advance, and judge whether the water injection is successful based on the temperature difference before and after the water pump is started and the water temperature after a period of water injection.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The related technology heats the water injection pipe before water injection begins. Although this can reduce the possibility of ice blockage in the water injection pipe, it will consume more power and increase the overall power consumption of the refrigerator.

[0007] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0012] In some embodiments, the method of judging the degree of ice blockage of the water injection pipe by detecting the temperature change in the ice grid before and after water injection includes: when the water injection pipe is ice-blocked and the temperature difference in the ice grid before and after water injection is less than a second threshold value, determining that the water injection pipe is completely ice-blocked; or, when the water injection pipe is ice-blocked and the temperature difference in the ice grid before and after water injection is greater than or equal to the second threshold value, determining that the water injection pipe is not completely ice-blocked.

[0013] In some embodiments, heating the water injection pipe to melt ice includes: when it is determined that the water injection pipe is completely blocked by ice, heating the water injection pipe to melt ice for a first time period; or, when it is determined that the water injection pipe is not completely blocked by ice, heating the water injection pipe to melt ice for a second time period; wherein the second time period is shorter than the first time period.

[0014] In some embodiments, the ice maker further includes a water injection pipe heating wire, and controlling the heating of the water injection pipe to melt ice includes: when it is determined that the water injection pipe is completely blocked by ice, controlling the water injection pipe heating wire to heat the water injection pipe to melt ice at a first power; or, when it is determined that the water injection pipe is not completely blocked by ice, controlling the water injection pipe heating wire to heat the water injection pipe to melt ice at a second power; wherein the second power is less than the first power.

[0015] In some embodiments, the method further includes: when the water injection pipe is not blocked by ice, determining whether the ice maker is short of water; and when the ice maker is short of water, controlling the ice maker to replenish water.

[0016] In some embodiments, the ice maker further includes an ice tray; determining whether the ice maker is short of water includes: detecting whether water flows into the ice tray; if the water injection pipe is not blocked by ice and no water flows into the ice tray, the ice maker is short of water; otherwise, the ice maker is not short of water.

[0024] The temperature of the unheated water injection pipe is lower than the water used for ice making. The first temperature is the temperature of the water injection pipe before water is injected, and the second temperature is the temperature of the water injection pipe after water is injected. Therefore, since the water injection process lasts for a short time, by comparing the second temperature with the first temperature, it can be reflected whether there is water remaining in the water injection pipe. Therefore, it is possible to analyze whether the water injection pipe is blocked by ice, and the ice blockage of the water injection pipe can be judged more accurately. Furthermore, the water injection pipe can be melted only when the water injection pipe is blocked by ice, which consumes less energy than heating the water injection pipe before each water injection in the related art.

[0034] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0035] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0036] Unless otherwise stated, the term "plurality" means two or more.

[0037] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0038] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0039] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0040] The refrigerator is equipped with an ice maker. The ice maker includes a water injection pipe and an ice tray. It is usually placed in a low-temperature environment such as a freezer, and may also include a water box. When the ice maker makes ice, water is injected into the ice tray through the water injection pipe. Due to the low operating environment temperature, the water used for ice making may accumulate in the water injection pipe and cause ice blockage. Therefore, the water injection pipe needs to be heated.

[0041] Combination Figure 1 The system for heating the water injection pipe includes a water injection pipe, an ice tray, a water injection pipe heating wire and a processor.

[0042] Figure 1 This is a schematic diagram of the system environment for heating the water injection pipe. Figure 1 As shown, the environment may include a water injection pipe 100, an ice tray 200, a water injection pipe heating wire 300, and a processor (not shown in the figure).

[0043] The ice making water enters the ice tray 200 through the water injection pipe 100 and freezes in the ice tray 200. After one round of ice making is completed, the ice tray 200 transfers the ice cubes, and the ice making water for a new round of ice making enters the ice tray 200 through the water injection pipe 100.

[0044] The water injection pipe 100 is provided with a temperature sensor (not shown in the figure) for detecting the temperature of the water injection pipe 100 in real time and sending the temperature information to the processor.

[0045] The water injection pipe heating wire 300 is arranged around the water injection pipe 100 and is used to heat the water injection pipe 100 to reduce the possibility of ice-making water freezing in the water injection pipe 100 or melt the ice that has already formed in the water injection pipe 100.

[0046] After receiving the temperature information sent by the temperature sensor, the processor determines whether it is necessary to heat the water injection pipe 100 to melt ice. If heating is required to melt ice, the water injection pipe heating wire 300 is controlled to heat the water injection pipe 100.

[0047] Combination Figure 2 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0048] S201, a temperature sensor detects the temperature of the water injection pipe before water is injected to obtain a first temperature.

[0049] S202, a temperature sensor detects the temperature of the water injection pipe after water is injected to obtain a second temperature.

[0050] Since the water injection pipe is in a low temperature working environment, the temperature of the water injection pipe is lower than the temperature of ice making water. Therefore, the second temperature is greater than or equal to the first temperature.

[0051] S203: The processor analyzes ice blockage of the water injection pipe according to the first temperature and the second temperature.

[0052] S204: When the water injection pipe is blocked by ice, the processor controls heating of the water injection pipe to melt the ice.

[0053] The first temperature detected before water injection is equivalent to the normal temperature of the water injection pipe. Due to the low working environment temperature, the first temperature is usually below 0 degrees. After the water injection is completed, if ice blockage occurs in the water injection pipe, ice-making water will remain in the water injection pipe. Since the specific heat capacity of water is large, the second temperature detected will also be large. Therefore, the first temperature and the second temperature can reflect whether ice-making water remains in the water injection pipe. According to the first temperature and the second temperature, the ice blockage of the water injection pipe can be analyzed to more accurately determine whether the water injection pipe is ice-blocked. Therefore, the water injection pipe can be heated to melt the ice only when the water injection pipe is ice-blocked, avoiding unnecessary heating without affecting the normal operation of the ice maker and reducing energy consumption.

[0054] Optionally, the temperature sensor detects the temperature of the water injection pipe after water injection, and this is performed a period of time after the water injection is completed. In the ice making process, whether or not the ice making water remains in the water injection pipe, heat exchange will be performed with the water injection pipe, causing the temperature of the water injection pipe to rise. Therefore, the second temperature can be detected again a period of time after the water injection is completed, so as to better judge whether there is ice making water remaining in the water injection pipe. For example, the temperature of the water injection pipe after water injection can be detected 30 seconds or 1 minute after the water injection is completed.

[0055] Optionally, the processor analyzes the ice blockage of the water injection pipe according to the first temperature and the second temperature, including: the processor determines that the water injection pipe is ice-blocked when the difference between the second temperature and the first temperature is greater than or equal to a first threshold, otherwise determines that the water injection pipe is not ice-blocked.

[0056] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0057] S301, a temperature sensor detects the temperature of the water injection pipe before water is injected to obtain a first temperature.

[0058] S302, a temperature sensor detects the temperature of the water injection pipe after water is injected to obtain a second temperature.

[0059] S303: When the difference between the second temperature and the first temperature is greater than or equal to the first threshold, the processor determines that the water injection pipe is blocked by ice; otherwise,

[0060] S304: When the difference between the second temperature and the first temperature is less than a first threshold, the processor determines that the water injection pipe is not blocked by ice.

[0061] The first threshold value can reflect the effect of ice-making water remaining in the water injection pipe on the natural cooling of the water injection pipe. The first threshold value is affected by the working environment temperature of the ice maker, the storage temperature of the ice-making water, and the time from the detection of the second temperature to the end of water injection. The lower the working environment temperature of the ice maker, the higher the storage temperature of the ice-making water, and the shorter the time from the detection of the second temperature to the end of water injection, the larger the first threshold value. The value range of the first threshold value is 10°C to 30°C. In practical applications, the specific value of the first threshold value can be obtained by experiments based on the specific model. For example, the working environment of the ice maker is -18°C, the storage temperature of the ice-making water is 10°C, and the time from the detection of the second temperature to the end of water injection is 20s, then the first threshold value can be set to 20°C or 15°C.

[0062] S305, when the water injection pipe is blocked by ice, the processor controls heating of the water injection pipe to melt the ice.

[0063] In this way, by setting the first threshold value according to the actual working condition of the refrigerator, it is possible to more accurately determine whether ice-making water remains in the water injection pipe, and furthermore, the ice blockage condition of the water injection pipe can be more accurately analyzed.

[0064] Optionally, in the case of ice blockage in the water injection pipe, before heating the water injection pipe to melt the ice, the degree of ice blockage in the water injection pipe can be determined by detecting the temperature change in the ice grid before and after water injection. The degree of ice blockage in the water injection pipe is used to adjust the total energy consumption of heating the water injection pipe to melt the ice. The more serious the ice blockage in the water injection pipe is, the higher the total energy consumption of heating the water injection pipe to melt the ice.

[0065] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0066] S401, a temperature sensor detects the temperature of the water injection pipe before water is injected to obtain a first temperature.

[0067] S402, a temperature sensor detects the temperature of the water injection pipe after water is injected to obtain a second temperature.

[0068] S403: When the difference between the second temperature and the first temperature is greater than or equal to the first threshold, the processor determines that the water injection pipe is blocked by ice.

[0069] S404: When the difference between the second temperature and the first temperature is less than a first threshold, the processor determines that the water injection pipe is not blocked by ice.

[0070] S405, the processor determines the degree of ice blockage of the water injection pipe by detecting the temperature change in the ice tray before and after water injection.

[0071] Optionally, an ice tray temperature sensor may be provided in the ice tray, and the temperature change in the ice tray before and after water injection may be detected by the ice tray temperature sensor.

[0072] S406: The processor controls heating of the water injection pipe to melt ice according to the degree of ice blockage of the water injection pipe.

[0073] The total energy consumption for heating the water injection pipe to melt the ice is adjusted according to the degree of ice blockage in the water injection pipe. The more serious the ice blockage in the water injection pipe is, the higher the total energy consumption for heating the water injection pipe to melt the ice is.

[0074] Optionally, according to the degree of ice blockage of the water injection pipe, controlling the heating of the water injection pipe to melt the ice includes: when it is determined that the water injection pipe is completely ice-blocked, heating the water injection pipe for a first time to melt the ice. Or, when it is determined that the water injection pipe is not completely ice-blocked, heating the water injection pipe for a second time to melt the ice. The second time is shorter than the first time. In this way, when the water injection pipe is completely ice-blocked, the duration of heating and melting the ice is longer, the total energy consumption is also higher, and the ice melting effect can be better improved.

[0075] Optionally, the first duration ranges from 5 minutes to 15 minutes. More specifically, the first duration can be 8 minutes or 10 minutes.

[0076] Optionally, the second duration ranges from 3 minutes to 10 minutes. More specifically, the second duration can be 5 minutes or 8 minutes.

[0077] Optionally, heating the water injection pipe to melt ice is accomplished by a water injection pipe heating wire. According to the degree of ice blockage in the water injection pipe, controlling the heating of the water injection pipe to melt ice includes: when it is determined that the water injection pipe is completely ice-blocked, the water injection pipe heating wire heats the water injection pipe to melt ice at a first power. Or, when it is determined that the water injection pipe is not completely ice-blocked, the water injection pipe heating wire heats the water injection pipe to melt ice at a second power. The second power is less than the first power. In this way, when the water injection pipe is completely ice-blocked, the operating power of the water injection pipe heating wire is higher, the total energy consumption is also higher, and ice can be melted more quickly.

[0078] Optionally, the first power ranges from 3 to 8 W. More specifically, the first power may be 6W.

[0079] Optionally, the second power ranges from 2 to 6 W. More specifically, the second power may be 4W.

[0080] The temperature change in the ice grid can reflect the amount of water entering the ice grid, that is, the amount of water actually passing through the water injection pipe. When the preset amount of water for each water injection is fixed, the degree of ice blockage in the water injection pipe can be judged by the temperature change in the ice grid. Therefore, if the temperature change in the ice grid is normal, it means that the water for ice making can still pass through the water injection pipe and the water injection pipe is not completely blocked by ice. If the temperature change in the ice grid is abnormal, it means that the water for ice making cannot pass through the water injection pipe and the water injection pipe is completely blocked by ice. In this way, the ice blockage of the water injection pipe can be further analyzed to adjust the total energy consumption of heating the water injection pipe to melt ice, which can better save energy consumption.

[0081] Optionally, when the water injection pipe is not blocked by ice, it is determined whether the ice maker is short of water. When the ice maker is short of water, the ice maker is controlled to replenish water. In this way, the technical effect of determining whether the ice maker is short of water can be additionally achieved.

[0082] Specifically, an ice tray temperature sensor is provided in the ice tray to detect whether water flows into the ice tray. The temperature difference in the ice tray before and after water is injected can be detected to detect whether water flows into the ice tray. Alternatively, a water box is connected to the outside of the ice maker to store water for ice making. The pressure change in the water box can be detected to detect whether water flows into the ice tray.

[0083] Further, by detecting the temperature difference in the ice tray before and after water is injected, detecting whether water flows into the ice tray includes: detecting the temperature in the ice tray before water injection to obtain a third temperature. Detecting the temperature in the ice tray after water injection to obtain a fourth temperature. If the difference between the fourth temperature and the third temperature is less than or equal to the second threshold, water flows into the ice tray; otherwise, no water flows into the ice tray.

[0084] Furthermore, by detecting the pressure change in the water box, it is detected whether water flows into the ice tray, including: when the water injection pipe is not blocked by ice, if the pressure in the water box changes before and after water injection, water flows into the ice tray; otherwise, no water flows into the ice tray.

[0085] Combination Figure 5 As shown, the embodiment of the present disclosure takes detecting whether water flows into the ice tray by detecting the temperature difference in the ice tray before and after water is injected as an example, and provides another method for controlling a refrigerator, including:

[0086] S501, a temperature sensor detects the temperature of the water injection pipe before water is injected to obtain a first temperature.

[0087] S502: The ice tray temperature sensor detects the temperature of the ice tray before water is added to obtain a third temperature.

[0088] S503, a temperature sensor detects the temperature of the water injection pipe after water is injected to obtain a second temperature.

[0089] S504, the processor determines that the water injection pipe is blocked by ice when the difference between the second temperature and the first temperature is greater than or equal to the first threshold.

[0090] S505: When the difference between the second temperature and the first temperature is less than a first threshold, the processor determines that the water injection pipe is not blocked by ice.

[0091] S506: When the water injection pipe is blocked by ice, the processor controls heating of the water injection pipe to melt the ice.

[0092] S507, when the water injection pipe is not blocked by ice, the ice tray temperature sensor detects the temperature in the ice tray after water injection to obtain a fourth temperature.

[0093] S508: When the difference between the fourth temperature and the third temperature is less than or equal to the second threshold, the processor confirms that the ice maker operates normally.

[0094] S509: When the difference between the fourth temperature and the third temperature is greater than the second threshold, the processor confirms that the ice maker is short of water.

[0095] As described in the above embodiment, the difference between the fourth temperature and the third temperature can reflect the amount of water entering the ice tray. If it is confirmed that the water injection pipe is not blocked by ice, if there is not enough water entering the ice tray, it can be said that the ice maker is short of water. The second threshold is related to the temperature of the ice tray before ice making starts and the storage temperature of the water for ice making. The lower the temperature of the ice tray before ice making starts and the higher the storage temperature of the water for ice making, the larger the second threshold. Optionally, the range of the second threshold is 10°C to 25°C. By way of example, the second threshold is 15°C or 20°C.

[0096] S510: When confirming that the ice maker is short of water, the processor controls the ice maker to replenish water.

[0097] Detection of water shortage in ice makers is a common topic in this field. In the case where the water injection pipe is determined to be not blocked by ice, the disclosed embodiment additionally analyzes whether the ice maker is short of water. Since the ice blockage of the water injection pipe has been analyzed before, the analysis result of whether the ice maker is short of water is more accurate. In this way, both the ice blockage of the water injection pipe and the water shortage of the ice maker can be analyzed, achieving more technical effects.
