[0066] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0067] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.
[0068] In addition, the terms "include" and "have" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such products or devices.
[0069] Refrigerator cold leakage is an important factor affecting the refrigerator's refrigeration. Door seal cold leakage is the most common cold leakage problem in refrigerators. Cold leakage can be caused by problems such as damaged door seals or poor installation. Such problems are not easy to detect, which seriously affects the refrigerator's refrigeration efficiency and causes increased energy consumption.
[0070] Before the refrigerator leaves the factory, it is possible to determine whether the door seal is leaking cold through manual observation or performance testing, but the detection efficiency and accuracy are low. When the user is using the refrigerator, if the door seal is damaged or poorly installed, causing cold leakage, it is difficult for the user to find out, which will affect the refrigeration efficiency of the refrigerator.
[0071] Therefore, the present application provides a refrigerator, in which multiple temperature sensors are arranged on the outside of the door seal of the door body, for detecting the temperature values of multiple positions on the outside of the door seal. Since the temperatures at these positions are affected by whether the door seal leaks cold, it is possible to automatically determine whether the door seal leaks cold based on these temperature values, thereby avoiding affecting the refrigeration efficiency of the refrigerator when manual observation is inaccurate or the user is unable to find that the door seal leaks cold. The present application can automatically detect whether the door seal leaks cold through multiple temperature sensors, thereby reducing the impact of the door seal leakage on the refrigeration efficiency of the refrigerator.
[0072] The technical solution of the present application is described in detail below in conjunction with specific embodiments. The following specific embodiments can be combined with each other or exist independently. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0073] First, the structure of the refrigerator provided by the present application is described. Figure 1 The refrigerator 10 includes a box body 101, a door body 102, and a door seal 103 ( Figure 1 ), multiple temperature sensors 104 ( Figure 1 ) and the main controller 105 ( Figure 1 not shown).
[0074] A storage room 11 is provided in the box body 101, and a door body 102 is used to open or close the storage room. Exemplarily, the storage room may include a refrigerator room, a freezer room, etc., which is not limited in the present application.
[0075] The door seal 103 is disposed on the door body 102 , and is used to seal the gap between the door body 102 and the box body 101 after the door body 102 is closed.
[0076] A plurality of temperature sensors 104 are disposed on the door body 102 and located outside the door seal 103 , and are configured to detect temperature values at a plurality of locations outside the door seal 103 .
[0077] The main controller 105 is disposed in the box 101 and connected to the plurality of temperature sensors 104. The main controller 105 is configured to obtain a plurality of first temperature values of the plurality of temperature sensors and determine whether the door seal 103 leaks cold air according to the plurality of first temperature values.
[0078] It can be understood that the temperature on the outside of the door seal 103 is easily affected by the door seal 103. If the door seal 103 leaks cold air, the temperature on the outside of the door seal 103 will also be reduced due to the cold air of the refrigerator. Then, the main controller 105 can determine whether the door seal 103 leaks cold air based on the temperature values of multiple temperature sensors 104.
[0079] In a possible implementation, the refrigerator 10 further includes an ambient temperature sensor ( Figure 1 (not shown), the ambient temperature sensor is disposed on the outside of the housing 101 and is configured to detect the temperature value of the environment in which the refrigerator 10 is located.
[0080] Figure 2 This is a schematic diagram of the structure of a door body 102 exemplified in this application. The door seal 103 is arranged on the inner side of the door body 102 so that when the door body 102 is closed, the door seal 103 seals the gap between the door body 102 and the box body 101. In order to more clearly describe the positions where the multiple temperature sensors 104 are arranged, Figure 3 This is a schematic diagram of a door seal 103 as exemplified in this application, Figure 3 As shown, a plurality of temperature sensors 104 are arranged on the inner side of the door body 102 and on the outer side of the door seal 103. It can be understood that Figure 3 The number of temperature sensors in the example is only an example, and the present application does not limit the number of temperature sensors.
[0081] In a possible implementation, for any one of the multiple temperature sensors 104, the temperature sensor is disposed on the outside of the door seal 103 through a metal sheet, the length of the metal sheet is greater than the length of the temperature sensor, and the width of the metal sheet is greater than the width of the temperature sensor.
[0082] For example, Figure 4 The schematic diagram of the temperature sensor of the present application example being located on a metal sheet is as follows: Figure 4 As shown, the housing of the temperature sensor can be configured as follows Figure 4 The metal sheet can be made of copper, aluminum or other materials with good heat conductivity. The temperature sensor can be located in the middle of the metal sheet. For example, the length of the metal sheet can be 50 cm (centimeter). By increasing the temperature sensing area of the temperature sensor through the metal sheet, the number of temperature sensors used can be reduced, thus saving costs.
[0083] In a possible implementation, the plurality of temperature sensors 104 and the main controller 105 may be connected via a wiring harness to achieve communication. Figure 5 This is a connection diagram between any temperature sensor 104 and the main controller 105 exemplified in this application. For example, the temperature sensor 104 can be connected to the serial peripheral interface (SPI) of the main controller 105 via a connecting line, and can also communicate through other interfaces, which is not limited in this application.
[0084] Based on the above refrigerator, Figure 6 FIG. 1 is a flow chart of a method for detecting cold leakage of a refrigerator door seal provided in an embodiment of the present application. The method can be executed by the main controller 105. Figure 6 As shown, the method comprises the following steps:
[0085] S601. Acquire multiple first temperature values, where the multiple first temperature values are temperature values at multiple locations outside the door seal measured by multiple temperature sensors.
[0086] The main controller may acquire a plurality of first temperature values, where the plurality of first temperature values are temperature values at a plurality of locations outside the door seal measured by a plurality of temperature sensors.
[0087] In one possible implementation, before multiple temperature sensors perform temperature detection, a detection instruction can be obtained. The detection instruction is used to instruct the multiple temperature sensors to perform temperature detection. The detection instruction can be generated by the main controller after a preset time length when the door body is detected to be closed. For example, the main controller can generate a detection instruction to instruct the temperature sensor to perform temperature detection 3 seconds after detecting that the door body is closed. After the multiple temperature sensors obtain the detection instruction, they can detect multiple first temperature values according to the detection instruction, that is, each temperature sensor can detect a first temperature value.
[0088] Multiple temperature sensors can perform temperature detection after receiving detection instructions, which can avoid being in the detection state all the time and achieve the purpose of energy saving and power saving.
[0089] S602: Determine whether the door seal is leaking cold air based on the multiple first temperature values.
[0090] After the main controller obtains multiple first temperature values, it can determine whether the door seal is leaking cold according to the multiple first temperature values. Specifically, there are the following ways:
[0091] Method 1
[0092] The main controller can calculate the difference between every two first temperature values among multiple first temperature values, and then compare each difference with a preset threshold. If there is a difference greater than the preset threshold, it means that the temperature at the location where the temperature sensor corresponding to the difference is located is abnormal, and the main controller can determine that the door seal is leaking cold.
[0093] Method 2
[0094] The main controller can obtain the ambient temperature value of the environment where the refrigerator is located, and then judge whether the door seal is leaking cold according to the ambient temperature value and multiple first temperature values. This method combines the ambient temperature value to judge whether the door seal is leaking cold, thereby improving the accuracy of the judgment.
[0095] In this embodiment, multiple first temperature values are obtained, and the multiple first temperature values are temperature values of multiple positions outside the door seal measured by multiple temperature sensors, and then it is determined whether the door seal is leaking cold according to the multiple first temperature values. The present application can automatically detect whether the door seal is leaking cold through multiple temperature sensors, and can reduce the impact of the door seal leaking cold on the refrigeration efficiency of the refrigerator.
[0096] The implementation of the above-mentioned method 2 is described in detail below.
[0097] Figure 7 FIG. 1 is a flow chart of another method for detecting cold leakage of a refrigerator door seal provided in an embodiment of the present application. The method can be executed by the main controller 105. Figure 7 As shown, the method comprises the following steps:
[0098] S701: Obtain a preset threshold.
[0099] S702: Determine a first difference between any two first temperature values among a plurality of first temperature values to obtain a plurality of first difference values.
[0100] S703: Determine whether there is a first difference value greater than a preset threshold among the multiple first difference values.
[0101] If there is a first difference greater than the preset threshold value among the multiple first differences, S704 is executed. If there is no first difference greater than the preset threshold value among the multiple first differences, it indicates that the door seal does not leak cold air.
[0102] Exemplarily, the preset threshold may be 3° C. (Celsius). When the first difference is greater than 3° C., it may be determined that the temperature at the location where the temperature sensor corresponding to the difference is located is abnormal.
[0103] S704: Obtain the ambient temperature value.
[0104] If there is a first difference value greater than a preset threshold value among multiple first differences, the main controller can further obtain the ambient temperature of the environment where the refrigerator is located. For example, the main controller can send a measurement instruction to the ambient temperature sensor to instruct the ambient temperature sensor to measure the ambient temperature. After the ambient temperature sensor measures the ambient temperature, it can send the corresponding ambient temperature value to the main controller.
[0105] S705: Determine whether the door seal is leaking cold air based on the multiple first temperature values and the ambient temperature values.
[0106] In one possible implementation, after obtaining the ambient temperature, the main controller can respectively determine the second differences between multiple first temperature values and the ambient temperature value, that is, obtain multiple second differences. If there is a second difference greater than a preset threshold among the multiple second differences, the main controller can determine that the door seal is leaking cold.
[0107] That is to say, since the position of the door measured by the temperature sensor can be directly in contact with the environment of the refrigerator, under normal circumstances, the temperature values measured by the temperature sensor and the ambient temperature sensor are consistent. If there is a difference in the temperature values measured by the temperature sensor and the ambient temperature sensor, it can be considered that the temperature of the temperature sensor is affected by the door seal.
[0108] In another possible implementation, due to the influence of factors such as the position of the sensor and the heat dissipation of the sensor, there will be a small difference between the temperature values measured by the temperature sensor and the ambient temperature sensor. After obtaining the ambient temperature, the main controller can respectively determine the second differences between the multiple first temperature values and the ambient temperature value, that is, obtain multiple second differences. If there is a second difference greater than a preset threshold value among the multiple second differences, and greater than the first threshold value, the main controller can determine that the door seal is leaking, wherein the first threshold value is greater than the preset threshold value. This can avoid the main controller from misjudging the door seal from leaking due to factors such as the position of the sensor and the heat dissipation of the sensor when determining that there is a difference in the temperature values measured by the temperature sensor and the ambient temperature sensor, thereby further improving the accuracy of the judgment.
[0109] In this embodiment, multiple first temperature values are obtained, and the multiple first temperature values are temperature values of multiple positions outside the door seal measured by multiple temperature sensors, and then the first difference between any two of the multiple first temperature values is determined, and it is determined whether there is a first difference greater than a preset threshold value among the multiple first difference values. If so, the ambient temperature value is obtained, and then it is determined whether the door seal is leaking cold based on the multiple first temperature values and the ambient temperature value. The present application combines the ambient temperature value to determine whether the door seal is leaking cold, improves the accuracy of the judgment, and can further reduce the impact of the door seal leaking cold on the refrigerator's refrigeration efficiency.
[0110] In a possible implementation, when determining whether the door seal is leaking cold air, the main controller may further determine the cold air leakage position of the door seal, as follows:
[0111] Figure 8 FIG. 1 is a flow chart of another method for detecting cold leakage of a refrigerator door seal provided in an embodiment of the present application. The method can be executed by the main controller 105. Figure 8 As shown, the method comprises the following steps:
[0112] S801. Acquire location information of a target temperature sensor, where the target temperature sensor is a temperature sensor corresponding to a second difference value greater than a preset threshold among multiple temperature sensors.
[0113] After determining that the door seal is leaking cold, the main controller may obtain position information of a target temperature sensor, where the target temperature sensor is a temperature sensor corresponding to a second difference value greater than a preset threshold value among multiple temperature sensors.
[0114] It can be understood that the location information of multiple temperature sensors can be stored in the main controller when they are installed. Exemplarily, the location information can include the identification of the temperature sensor and the identification of the installation location. The installation location identification can be represented by identification 1, identification 2, etc., such as Figure 3As shown, for example, mark 1 can represent the lower left side of the outer side of the door seal, and mark 2 can represent the upper right side of the outer side of the door seal. The present application does not limit the representation method of the installation position mark.
[0115] S802: Determine the cold leakage position of the door seal according to the position information.
[0116] After determining the position information, the main controller can determine the cold leakage position of the door seal, thereby prompting the user with a more accurate cold leakage position of the door seal.
[0117] In this embodiment, after determining that the door seal is leaking cold air, the main controller can obtain the position information of the target temperature sensor, and then determine the cold air leakage position of the door seal based on the position information, thereby providing the user with a more accurate door seal leakage position.
[0118] Fig. 9 The present application provides a flow chart of another method for detecting cold leakage of a refrigerator door seal, which can be executed by the main controller 105. Fig. 9 As shown, the method comprises the following steps:
[0119] S901. Acquire multiple first temperature values of multiple temperature sensors.
[0120] S902: Obtain a preset threshold.
[0121] S903: Determine a first difference between any two first temperature values among the multiple first temperature values to obtain multiple first difference values.
[0122] S904: Determine whether there is a first difference value greater than a preset threshold among the multiple first difference values.
[0123] If there is a first difference greater than the preset threshold value among the multiple first differences, S905 is executed. If there is no first difference greater than the preset threshold value among the multiple first differences, it means that the door seal is not leaking cold air, and subsequent judgment is not required.
[0124] S905: Obtain the ambient temperature value.
[0125] S906: Determine whether the door seal is leaking cold air based on the multiple first temperature values and the ambient temperature values.
[0126] If yes, execute S907, if no, it means that the door seal is not leaking cold.
[0127] S907: Output a prompt message, where the prompt message is used to prompt that the door seal is leaking cold air.
[0128] For the detailed description of the above steps, please refer to the above embodiments, which will not be repeated here.
[0129] In a possible implementation, the prompt information may include a cold leakage position of the door seal, so that users and maintenance personnel can quickly locate the cold leakage position of the door seal. For example, the cold leakage position may be position information of a target temperature sensor.
[0130] Exemplarily, the main controller may output the prompt information in one or more of the following ways:
[0131] Method 1: Sending an alarm through a related device, such as a buzzer, a flashing light, a voice playback device, etc.
[0132] Method 2: Output prompt information through the display panel.
[0133] Mode 3: Sending prompt information to the user's terminal device through a communication module. The communication module may be, for example, Wireless Fidelity (WIFI) or other communication modules, which is not limited in the present application.
[0134] In this embodiment, multiple first temperature values are obtained, and the multiple first temperature values are temperature values of multiple positions on the outside of the door seal measured by multiple temperature sensors. Then, the first difference between any two of the multiple first temperature values is determined, and it is determined whether there is a first difference greater than a preset threshold value among the multiple first difference values. If so, the ambient temperature value is obtained, and then it is determined whether the door seal is leaking cold based on the multiple first temperature values and the ambient temperature value. If the door seal is leaking cold, a prompt message is output, and the prompt message is used to prompt that the door seal is leaking cold. The present application combines the ambient temperature value to determine whether the door seal is leaking cold, and promptly notifies the user of the door seal's leakage of cold, thereby improving the accuracy of the judgment and further reducing the impact of the door seal's leakage of cold on the refrigerator's refrigeration efficiency.
