[0014] In this embodiment, the refrigerator includes a box body provided with a storage compartment, a door body for opening or closing the storage compartment, a door seal provided on the door body, a control component provided in the box body, and multiple groups of temperature sensors provided in the storage compartment. For any group of temperature sensors, it includes two temperature sensors, one of which is close to the door seal and the other is far from the door seal. The control component is configured to obtain multiple temperature values through multiple groups of temperature sensors, determine the temperature difference corresponding to each group of temperature sensors, and determine whether the door seal leaks cold according to the multiple temperature differences corresponding to the multiple groups of temperature sensors. In this application, multiple groups of temperature sensors can automatically detect whether the door seal leaks cold, which can reduce the influence of door seal cold leakage on the refrigeration efficiency of the refrigerator.
[0015] In some embodiments of this application, the control component is configured to:
[0016] Obtain a preset threshold;
[0017] Determine whether there is a temperature difference greater than the preset threshold among the multiple temperature differences;
[0018] If so, determine that the door seal leaks cold.
[0019] In this embodiment, if there is a temperature difference greater than the preset threshold among the multiple temperature differences, it indicates that the temperature value corresponding to the temperature sensor close to the door seal is abnormal, and it can be determined that the door seal leaks cold.

[0026] In some embodiments of this application, the control component is configured to:

[0041] In some embodiments of the present application, for any group of temperature sensors in the multiple groups of temperature sensors, the two temperature sensors are located at the same horizontal position.
[0042] In this embodiment, two temperature sensors are set at the same horizontal position, so that when the door seal does not leak cold, the temperatures sensed by the two temperature sensors are the same.

[0074] To make the objectives, embodiments, and advantages of this application clearer, the following will clearly and completely describe the exemplary embodiments of this application with reference to the accompanying drawings in the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only a part of the embodiments of this application, rather than all of the embodiments.
[0075] It should be noted that the brief description of the terms in this application is only for facilitating the understanding of the subsequent described embodiments, rather than intending to limit the embodiments of this application. Unless otherwise specified, these terms should be understood in their ordinary and common meanings.
[0076] In addition, the terms "comprising" and "having" and any variations thereof are intended to cover but not exclude inclusion. For example, a product or device comprising a series of components does not necessarily have to be limited to those components clearly listed, but may include other components not clearly listed or inherent to these products or devices.
[0077] Refrigerant leakage in the refrigerator is an important factor affecting the refrigeration of the refrigerator. Cold air leakage through the door seal is the most common cold air leakage problem in the refrigerator. Due to problems such as damage or poor installation of the door seal, cold air leakage will occur. Such problems are not easy to detect, seriously affecting the refrigeration efficiency of the refrigerator and increasing energy consumption.
[0078] Before the refrigerator leaves the factory, it is possible to determine whether the door seal leaks cold through manual observation or performance testing. The detection efficiency is low and the accuracy is low. If the cold air leakage is caused by damage or poor installation of the door seal, it is also difficult for users to discover, which will affect the refrigeration efficiency of the refrigerator.
[0079] Therefore, this application provides a refrigerator. Multiple groups of temperature sensors are arranged in the storage chamber. In each group of temperature sensors, one temperature sensor is close to the door seal and the other is far from the door seal. If the door seal leaks cold, the cold air in the refrigerator exchanges with the hot air in the environment where the refrigerator is located. The temperature sensor close to the door seal is easily affected, while the temperature sensor far from the door seal is not easily affected. Whether the door seal leaks cold can be determined according to the temperature difference of multiple groups of temperature sensors, avoiding affecting the refrigeration efficiency of the refrigerator when manual observation is inaccurate or users cannot discover the cold air leakage of the door seal.
[0080] The technical solution of the present application will be described in detail below in conjunction with specific embodiments. These several specific embodiments may be combined with each other or exist independently. For the same or similar concepts or processes, they may not be described again in some embodiments. The embodiments of the present application will be described below in conjunction with the drawings.
[0081] First, the structure of the refrigerator provided by the present application will be described. Figure 1 As shown in the schematic structural diagram of a refrigerator provided by an embodiment of the present application, the refrigerator 10 includes a box body 101, a door body 102, a door seal 103, multiple groups of temperature sensors 104, and a control component 105 ( Figure 1 not shown in the figure).
[0082] Among them, a storage chamber is provided inside the box body 101, and the door seal 103 is used to seal the gap between the door body 102 and the box body 101 after the door body 102 is closed.
[0083] Multiple groups of temperature sensors 104 are arranged in the storage chamber. For any group of temperature sensors, it includes two temperature sensors, one of which is close to the door seal 103 and the other is far from the door seal 103.
[0084] In a possible implementation manner, as Figure 1 shown, the storage chamber is provided with an access opening. Multiple groups of temperature sensors may include 4 groups of temperature sensors, and the 4 groups of temperature sensors are respectively arranged on the four side walls adjacent to the access opening. The leakage of cold of the door seal 103 can be detected by the 4 groups of temperature sensors on the top, bottom, left, and right.
[0085] In another possible implementation manner, the number of temperature sensors can be increased accordingly according to the size of the storage chamber. The present application does not limit the number of temperature sensors.
[0086] In a possible implementation manner, Figure 2 As shown in the schematic diagram of a group of temperature sensors in an embodiment of the present application on a side wall, the temperature sensor a is close to the door seal 103, the temperature sensor b is far from the door seal 103, and the temperature sensor a and the temperature sensor b are in the same horizontal position, which can make the temperatures sensed by the temperature sensor a and the temperature sensor b consistent when the door seal 103 does not leak cold.
[0087] Alternatively, the temperature sensor a and the temperature sensor b may not be in the same horizontal position. As Figure 3 shown, the height difference between the temperature sensor a and the temperature sensor b is less than a preset value to ensure that the temperatures sensed by the temperature sensor a and the temperature sensor b are consistent when the door seal 103 does not leak cold.
[0088] The control component 105 is electrically connected to multiple groups of temperature sensors 104. The control component 105 is configured to obtain multiple temperature values through the multiple groups of temperature sensors 104, determine the temperature difference corresponding to each group of temperature sensors, and determine whether the door seal 103 leaks cold according to the multiple temperature differences corresponding to the multiple groups of temperature sensors.
[0089] It can be understood that if the door seal 103 leaks cold, the cold air inside the refrigerator exchanges with the hot air in the environment where the refrigerator is located. The temperature sensors close to the door seal 103 are easily affected, while the temperature sensors far from the door seal 103 are not easily affected. Then, the control component 105 determines whether the door seal 103 leaks cold according to the temperature differences of the multiple groups of temperature sensors, avoiding the influence on the refrigeration efficiency of the refrigerator when manual observation is inaccurate or the user cannot find that the door seal leaks cold.
[0090] In a possible implementation manner, Figure 4 FIG. is a schematic structural diagram of another refrigerator provided by an embodiment of the present application. As Figure 4 shown, the door body 102 includes a first door body 21 and a second door body 22.
[0091] Exemplarily, the storage compartment may include a refrigerating compartment 11 and a freezing compartment ( Figure 4 not shown in the figure). The first door body 21 can be used to open or close the refrigerating compartment 11, and the second door body 22 can be used to open or close the freezing compartment. It can be understood that the refrigerating compartment and the freezing compartment are independent compartments that are opened or closed through different door bodies. Door seals 103 are respectively provided on the first door body 21 and the second door body 22 ( Figure 4 not shown in the figure).
[0092] The door seal 103 provided on the first door body 21 is used to seal the gap between the first door body 21 and the cabinet body 101 after the first door body 21 is closed. The door seal 103 provided on the second door body 22 is used to seal the gap between the second door body 22 and the cabinet body 101 after the second door body 22 is closed.
[0093] Taking the first door body 21 as an example, Figure 5 FIG. is a schematic structural diagram of a door body according to an example of the present application. The door seal 103 is provided inside the first door body 21 so that when the first door body 21 is closed, the door seal 103 seals the gap between the first door body 21 and the cabinet body 101.
[0094] In a possible implementation, the multiple sets of temperature sensors include 8 sets of temperature sensors. 4 sets of temperature sensors are arranged in the refrigerating chamber 11, and the other 4 sets of temperature sensors are arranged in the freezing chamber. Specifically, the 4 sets of temperature sensors in the refrigerating chamber 11 can be arranged on the four side walls adjacent to the access opening of the refrigerating chamber 11, and the 4 sets of temperature sensors in the freezing chamber can be arranged on the four side walls adjacent to the access opening of the freezing chamber. For a set of temperature sensors arranged on each side wall, reference can be made specifically to Figure 2 and Figure 3 .
[0095] For each independent compartment described above, multiple sets of temperature sensors can be respectively arranged, which can realize the detection of cold leakage of the door seals corresponding to multiple compartments.
[0096] In a possible implementation, the multiple sets of temperature sensors 104 and the control component 105 can be connected by a wire harness to realize communication. Exemplarily, the temperature sensor can be connected to the Serial Peripheral Interface (SPI) interface of the control component 105 through a connection wire, and can also communicate through other interfaces. This application does not limit this.
[0097] It can be understood that the control component 105 can identify the multiple sets of temperature sensors. For example, Table 1:
[0098] Table 1
[0099] Combination Temperature Sensor 1 Temperature Sensor 2 A Ax Ay B Bx By C Cx Cy D Dx Dy
[0100] The control component 105 can calculate the temperature difference based on the values of the temperature sensors in each group according to the above identification. Among them, x represents that the temperature sensor is close to the door seal, and y represents that the temperature sensor is far from the door seal.
[0101] In a possible implementation, the refrigerator further includes an ambient temperature sensor (not shown in the figure). The ambient temperature sensor is arranged outside the cabinet 101 and is configured to detect the ambient temperature value of the environment where the refrigerator is located. This ambient temperature value can be used to determine a preset threshold. For specific reference, see the following embodiments.
[0102] Based on the above refrigerator, Figure 6 is a schematic flowchart of a method for detecting cold leakage of the door seal of a refrigerator provided by an embodiment of the present application. This method can be executed by the above control component 105. As Figure 6 shown, this method includes the following steps:
[0103] S601. Obtain multiple temperature values through multiple sets of temperature sensors.
[0104] The control component can obtain multiple temperature values through multiple groups of temperature sensors to acquire the temperature values at multiple positions inside the storage chamber.
[0105] In a possible implementation, before the multiple groups of temperature sensors perform temperature detection, a detection instruction can be obtained. The detection instruction is used to instruct the multiple groups of temperature sensors to perform temperature detection.
[0106] Exemplarily, the detection instruction can be generated according to the following method:
[0107] The control component can detect the state of the door body, and the state is open or closed. If the state of the door body is open, determine the first duration of the current opening of the door body. If the first duration is greater than a preset duration, then generate a detection instruction, and the detection instruction is used to instruct the multiple groups of temperature sensors to perform temperature detection.
[0108] Exemplarily, the preset duration can be 1 hour, or it can be other values. This application does not make a limitation on this. The multiple groups of temperature sensors can perform temperature detection after obtaining the detection instruction, which can avoid being in the detection state all the time, achieve the purpose of energy saving and power saving, and can also exclude the influence of the user opening and closing the door on the temperature detected by the temperature sensors.
[0109] S602. Determine the temperature difference corresponding to each group of temperature sensors.
[0110] After obtaining the temperature values of the multiple groups of temperature sensors, the control component can determine the temperature difference corresponding to each group of temperature sensors. Specifically, the control component can calculate the difference between the temperature values detected by two temperature sensors in each group of temperature sensors according to the identifiers exemplified in Table 1, and thus obtain multiple temperature differences of the multiple groups of temperature sensors.
[0111] S603. Determine whether the door seal leaks cold based on the multiple temperature differences corresponding to the multiple groups of temperature sensors.
[0112] The control component can determine whether the door seal leaks cold based on the multiple temperature differences corresponding to the multiple groups of temperature sensors.
[0113] In this embodiment, multiple temperature values are obtained through multiple groups of temperature sensors, the temperature difference corresponding to each group of temperature sensors is determined, and whether the door seal leaks cold is determined based on the multiple temperature differences corresponding to the multiple groups of temperature sensors. This application can automatically detect whether the door seal leaks cold through multiple groups of temperature sensors, and can reduce the influence of door seal cold leakage on the refrigeration efficiency of the refrigerator.
[0114] Figure 7 It is a schematic flowchart of another method for detecting cold leakage of the door seal of a refrigerator provided by an embodiment of this application. This method can be executed by the above control component 105, as Figure 7 shown. This method includes the following steps:
[0115] S701. Obtain multiple temperature values through multiple groups of temperature sensors.
[0116] S702. Determine the temperature difference corresponding to each group of temperature sensors.
[0117] S703. Obtain a preset threshold.
[0118] S704. Determine whether there is a temperature difference greater than the preset threshold among the multiple temperature differences.
[0119] If there is a temperature difference greater than the preset threshold among the multiple temperature differences, execute S705; if there is no temperature difference greater than the preset threshold among the multiple temperature differences, execute S706.
[0120] Exemplarily, the preset threshold can be 2 °C (Celsius). When a certain temperature difference is greater than 2 °C, it can be determined that the door seal leaks cold.
[0121] That is to say, in the case where the door seal does not leak cold, the temperature sensor close to the door seal in each group of temperature sensors is not affected by the hot air in the environment where the refrigerator is located, and the temperature value detected by this temperature sensor is relatively close to the temperature value detected by another temperature sensor. When a certain temperature difference is greater than the preset threshold, it means that the temperature value detected by the temperature sensor close to the door seal in the group of temperature sensors corresponding to this temperature difference is affected by the hot air in the environment where the refrigerator is located, resulting in a large temperature difference. Then, at this time, it can be determined that the door seal leaks cold.
[0122] In a possible implementation manner, in order to prevent the user from putting ingredients with a high temperature into the storage room and this food is close to a certain temperature sensor, resulting in an abnormal temperature difference, the control component can compare the temperature difference greater than the preset threshold with a first threshold. If this temperature difference is greater than the first threshold, it can be determined that this abnormal temperature difference is caused by the user putting ingredients with a high temperature. Among them, the first threshold is greater than the preset threshold. At this time, the control component can determine that the door seal does not leak cold. If this temperature difference is not greater than the first threshold, it can be determined that this abnormal temperature difference is not caused by the user putting ingredients with a high temperature. Then, the control component can determine that the door seal leaks cold.
[0123] S705. Determine that the door seal leaks cold.
[0124] S706. Determine that the door seal does not leak cold.
[0125] In this embodiment, multiple temperature values are obtained through multiple groups of temperature sensors, the temperature difference corresponding to each group of temperature sensors is determined, a preset threshold is obtained, and it is determined whether there is a temperature difference greater than the preset threshold among the multiple temperature differences. If there is a temperature difference greater than the preset threshold among the multiple temperature differences, it is determined that the door seal leaks cold. If there is no temperature difference greater than the preset threshold among the multiple temperature differences, it is determined that the door seal does not leak cold. In this application, multiple groups of temperature sensors can automatically detect whether the door seal leaks cold, which can reduce the impact of door seal cold leakage on the refrigeration efficiency of the refrigerator.
[0126] Due to the limited heat preservation performance of the door seal, the temperature values detected by the temperature sensors close to the door seal are easily affected by the external environment of the refrigerator. At different ambient temperatures, the difference between the temperature values detected by this temperature sensor and the temperature sensors far from the door seal is different, and the control component can determine different thresholds based on different ambient temperatures.
[0127] Next, a detailed description of how to obtain the preset threshold will be given.
[0128] Figure 8 FIG. is a schematic flowchart of another method for detecting cold leakage of the door seal of a refrigerator provided by an embodiment of the present application. This method can be executed by the above control component 105, as Figure 8 shown, this method includes the following steps:
[0129] S801. Obtain the current ambient temperature value through the ambient temperature sensor.
[0130] S802. Obtain a preset correspondence, where the preset correspondence includes multiple preset temperature ranges and the thresholds corresponding to each preset temperature range.
[0131] Exemplarily, the preset correspondence can refer to Table 2.
[0132] Table 2
[0133] Preset Temperature Range Threshold Range 1 Y1 Range 2 Y2 Range 3 Y3 Range 4 Y4
[0134] S803. Determine the preset threshold according to the current ambient temperature value and the preset correspondence.
[0135] The control component can, according to the current ambient temperature value, determine the preset temperature range in which the current ambient temperature value is located in the preset correspondence, and then determine the threshold corresponding to the preset temperature range as the preset threshold.
[0136] In this embodiment, different thresholds are determined according to different ambient temperatures, reducing the influence of the current ambient temperature on the internal problems of the box body, thereby improving the accuracy of door seal judgment.
[0137] In a possible implementation, when the control component determines whether the door seal leaks cold, it can further determine the cold leakage position of the door seal, specifically as follows:
[0138] Figure 9 The flowchart of another method for detecting cold leakage of the door seal of a refrigerator provided by an embodiment of the present application can be executed by the above control component 105, as Figure 9 shown. The method includes the following steps:
[0139] S901. Determine the target group of temperature sensors, where the temperature difference corresponding to the target group of temperature sensors is greater than a preset threshold.
[0140] After determining that the door seal leaks cold, the control component can determine the target group of temperature sensors with a temperature difference greater than the preset threshold, so as to obtain the position information of the target group of temperature sensors.
[0141] S902. Obtain the position information of the target group of temperature sensors.
[0142] It can be understood that the position information of multiple temperature sensors can be stored in the memory of the control component during installation. Exemplarily, the position information can include the identifier of the temperature sensor and the identifier of its installation position. The installation position identifier can be represented by identifier 1, identifier 2, etc. As Figure 1 shown, for example, identifier 1 can represent the left side wall of the storage compartment, and identifier 2 can represent the right side wall of the storage compartment. The present application does not limit the representation method of the installation position identifier.
[0143] Exemplarily, after the control component determines the target group of temperature sensors, it can obtain the installation position identifier of the temperature sensor closest to the door seal in the target group of temperature sensors in the memory.
[0144] S903. Determine the cold leakage position of the door seal according to the position information.
[0145] After determining the position information, the control component can determine the cold leakage position of the door seal, so as to prompt the user with a more accurate cold leakage position of the door seal. The cold leakage position can be the position of the door seal on the same horizontal line as the installation position of the temperature sensor closest to the door seal in the target group of temperature sensors.
[0146] In this embodiment, after the control component determines that the door seal leaks cold, it can obtain the position information of the target group of temperature sensors, and then determine the cold leakage position of the door seal according to the position information, so as to prompt the user with a more accurate cold leakage position of the door seal.
[0147] Figure 10 The flowchart of another method for detecting cold leakage of the door seal of a refrigerator provided by an embodiment of the present application can be executed by the above control component 105, asFigure 10 As shown, the method includes the following steps:
