Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, "a plurality of" means two or more, unless otherwise specified.

[0040] In the description of the present application, it needs to be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0041] Referring to Figure 1 , Figure 1 is a schematic diagram of the external structure of a refrigerator 100 provided by an embodiment of the present application. The refrigerator 100 of the present embodiment has a shape similar to a rectangular parallelepiped. The refrigerator includes a cabinet defining a storage space and a plurality of door bodies provided at the opening of the cabinet. The door body includes a door body shell located outside the cabinet, a door body inner container located inside the cabinet, an upper end cover, a lower end cover, and a thermal insulation layer located between the door body shell, the door body inner container, the upper end cover, and the lower end cover. Generally, the thermal insulation layer is filled with foaming material. The cabinet is provided with a cavity, wherein the cavity includes a component storage cavity for placing components in the refrigerator, such as a compressor cabin, and also includes a storage space for storing food and the like. The cabinet door of the refrigerator is provided with a display screen 10, which is used to display the operating parameters of the refrigerator and receive touch operations of the user.

[0042] Referring to Figure 2 , Figure 2 is a schematic diagram of the internal structure of a refrigerator provided by an embodiment of the present application. The storage space can be divided into a plurality of storage compartments. The storage compartments can be configured as refrigeration compartments 11 and freezing compartments 12 according to different uses, and can also include variable-temperature compartments, vacuum drawers, humidity-maintaining drawers, and the like. Each storage compartment corresponds to one or more door bodies, for example, in Figure 2The upper storage chamber is provided with a double-door body, wherein the door body is pivotally arranged at the opening of the box body, and can also be a drawer type opening to realize drawer type storage. Figure 3 , Figure 3 The refrigerator 100 provided by the embodiment of the present application comprises a compressor 1, an evaporator 2, a drying filter (not shown in the figure), a capillary tube 3, a condenser 4 and a gas-liquid separator (not shown in the figure). The working process of the refrigerating system comprises a compression process, a condensation process, a throttling process and an evaporation process. The compression process is that when the power cord of the refrigerator is plugged in and the contact of the temperature controller is connected, the compressor 1 starts to work, the low-temperature and low-pressure refrigerant is sucked into the compressor 1, is compressed into high-temperature and high-pressure superheated gas in the cylinder of the compressor 1 and is discharged into the condenser 4. The condensation process is that the high-temperature and high-pressure refrigerant gas is cooled by the condenser 4, the temperature is continuously reduced, is gradually cooled into saturated vapor at normal temperature and high pressure and is further cooled into saturated liquid, the temperature no longer reduces, the temperature at this time is called condensation temperature, and the pressure of the refrigerant in the whole condensation process is almost unchanged. The throttling process is that the saturated liquid of the refrigerant after condensation is filtered to remove water and impurities by the drying filter and flows into the capillary tube 3, is throttled and reduced in pressure by the capillary tube 3, and the refrigerant becomes wet vapor at normal temperature and low pressure. The evaporation process is that the wet vapor at normal temperature and low pressure starts to absorb heat to vaporize in the evaporator 2, not only reduces the temperature of the evaporator 2 and the surrounding thereof, but also makes the refrigerant into low-temperature and low-pressure gas. The refrigerant discharged from the evaporator 2 returns to the compressor 1 again after passing through the gas-liquid separator, the above process is repeated, the heat in the refrigerator is transferred to the air outside the box, and the purpose of refrigeration is achieved.

[0043] Referring to Figure 4 , Figure 4 is a setting diagram of the door shelf provided by the embodiment of the present application, and it can be understood that Figure 4The arrangement of the shelves, door shelves and weight sensors in the storage compartment is only an example and is not limited thereto, and in actual applications, the arrangement can be made according to actual needs. It is assumed that the refrigerator has two box doors, a right box door 101 and a left box door 102, three shelves in the refrigeration compartment 11, and two refrigeration drawers at the bottom, the right box door 101 is internally provided with a right box door first door shelf 1011 and a right box door second door shelf 1012, and the left box door 102 is internally provided with a left box door first door shelf 1021 and a left box door second door shelf 1022. Among them, a weight sensor 201 is arranged in the right box door second door shelf 1012, and the weight sensor 201 detects the weight of the food placed on the right box door second door shelf 1012. It can be understood that only the weight sensor 201 is arranged on the right box door second door shelf 1012 in the figure, and in other embodiments, the weight sensor 201 can also be arranged on the remaining door shelves, such as the right box door first door shelf 1011, the left box door first door shelf 1021 and the left box door second door shelf 1022.

[0044] Further, at least one weight sensor can be arranged on each door shelf, and the number and position of the weight sensors 201 can be determined according to the size of the door shelf. For example, when the size of the door shelf is large, one weight sensor 201 can be arranged on each of the left and right sides of the door shelf, and then the average value of the two weight sensors 201 can be calculated as the weight of the food when the weight of the food in the door shelf is counted. Alternatively, for a door shelf provided with a partition, i.e., the door shelf is divided into a plurality of storage spaces by a baffle, one weight sensor 201 can be arranged in each storage space, and the weight sensor 201 only detects the weight of the food in the current storage space.

[0045] Specifically, the temperature adjusting component is made of an insulating and heat-insulating material. For example, the insulating and heat-insulating material is asbestos, rubber, glass fiber or the like.

[0046] In the embodiment of the present application, by isolating and insulating the weight sensor 201, the temperature of the refrigerator can slowly change within a certain period of time after the door is opened, and the phenomenon that the weight sensor 201 cannot accurately measure the weight due to sudden temperature change can be avoided.

[0047] Specifically, the temperature adjusting component is made of an insulating and heat-insulating material. For example, the insulating and heat-insulating material is asbestos, rubber, glass fiber or the like.

[0048] In the embodiment of the present application, the weight sensor 201 is surrounded by the insulating thermal insulation material, which can better play a thermal insulation effect.

[0049] Specifically, the door shelf is provided with a plurality of grooves, and the temperature adjusting component is arranged in the grooves; wherein the depth of the grooves is less than the height of the temperature adjusting component.

[0050] For example, referring to Figure 5 , Figure 5 is a first setting mode schematic diagram of the weight sensor provided by the embodiment of the present application, and the temperature adjusting component wrapped around the weight sensor 201 is arranged at the bottom of the door shelf, which protrudes from the surface of the bottom of the door shelf, so that after the food material is placed, the food material can be in full contact with the temperature adjusting component, thereby pressing the weight sensor 201, and ensuring that the weight sensor 201 can detect the weight of the food material.

[0051] Specifically, the temperature adjusting component includes a semiconductor refrigeration sheet, and the semiconductor refrigeration sheet is arranged on one side of the weight sensor; wherein the semiconductor refrigeration sheet is connected to the controller of the refrigerator.

[0052] For example, referring to Figure 6 , Figure 6 is a second setting mode schematic diagram of the weight sensor provided by the embodiment of the present application, the temperature adjusting component includes a semiconductor refrigeration sheet 202, the semiconductor refrigeration sheet 202 is arranged on one side of the weight sensor 201 and is in full contact with the weight sensor 201, and the semiconductor refrigeration sheet 202 is a new type of cooling device that achieves refrigeration through Peltier effect. When direct current passes through an electric couple composed of two different semiconductor materials in series, heat can be absorbed and heat can be emitted at both ends of the electric couple, thereby achieving refrigeration.

[0053] Specifically, the refrigerator further includes:

[0054] a temperature sensor arranged in the door shelf, for acquiring the real-time temperature of the environment in which the weight sensor 201 is located;

[0055] The controller is configured to: acquire the real-time temperature detected by the temperature sensor; when the real-time temperature is higher than a preset high temperature threshold, start the semiconductor refrigeration sheet, and when the real-time temperature is lower than the high temperature threshold, turn off the semiconductor refrigeration sheet.

[0056] For example, referring to Figure 7 , Figure 7The first working flowchart of the controller in the refrigerator is provided in the embodiment of the present application, the controller is configured to execute steps S11-S16, for different types of weight sensors, there is an optimal temperature range for its work, therefore, the optimal temperature range corresponding to the current type of weight sensor 201 is written in the controller of the refrigerator in advance, the optimal temperature range is composed of a high temperature threshold and a low temperature threshold, the high temperature threshold is greater than the low temperature threshold. The temperature sensor can be arranged close to the weight sensor 201, such as being in close contact with the weight sensor 201, for collecting the real-time temperature of the environment where the weight sensor 201 is located, when the user opens the door, the temperature sensor can quickly perceive the temperature change. The real-time temperature detected by the temperature sensor is acquired, when the real-time temperature is higher than the preset high temperature threshold, the semiconductor refrigeration sheet 202 is started, the semiconductor refrigeration sheet 202 starts refrigeration after being powered on, which can reduce the temperature around the weight sensor 201, and when the real-time temperature is detected to be lower than the high temperature threshold, the semiconductor refrigeration sheet 202 is turned off.

[0057] In the embodiment of the present application, when the temperature of the weight sensor 201 is detected to be too high, the semiconductor refrigeration sheet 202 is started in time to cool down, which can ensure that the temperature of the environment where the weight sensor 201 is located is not too high, and improve the accuracy of the detection data of the weight sensor 201.

[0058] Specifically, the refrigerator is also provided with a door switch state detection device, which is arranged on the door of the door shelf where the weight sensor is distributed, for detecting the opening and closing of the door. At this time, the weight sensor is arranged in the second door shelf 1012 of the right door, and the door shelf of the left door 102 is not provided with a weight sensor, so at this time, the door switch state detection device only needs to be arranged at the corresponding position of the right door 101, and the left door 102 does not need to be arranged.

[0059] Specifically, the real-time temperature detected by the temperature sensor is acquired, including: when the door of the storage compartment is detected to be opened, the real-time temperature detected by the temperature sensor is acquired.

[0060] Exemplarily, since the door shelf will be in full contact with indoor air when the user opens the box door, the high-temperature gas will cause the temperature of the environment where the weight sensor 201 is located to rise, thereby causing the weight sensor 201 to detect inaccurate data, and therefore the controller starts the temperature sensor only when it is detected by the door switch state detection device that the box door (the box door where the door shelf with the weight sensor 201 is located) is opened, thereby avoiding the temperature sensor from being in a working state all the time and wasting power, and thereby saving the power of the refrigerator. In addition, even if the box door is opened, there will be no need to start the semiconductor refrigeration piece 202, such as when the box door is opened for a short time, the temperature sensor has returned to a low-temperature environment before detecting a temperature change, at which time the semiconductor refrigeration piece 202 can not be started, or the indoor environment temperature is relatively low, and after the box door is opened, the temperature sensor detects that the real-time temperature is still lower than the high-temperature threshold, at which time the semiconductor refrigeration piece 202 can also not be started.

[0061] Specifically, the temperature regulating component further comprises a heater, which is arranged on one side of the weight sensor, and the heater is connected to the controller of the refrigerator.

[0062] Exemplarily, referring to Figure 8 , Figure 8 is a third arrangement of the weight sensor 201 provided by the embodiment of the present application, and the temperature regulating component further comprises a heater 203 in addition to the semiconductor refrigeration piece 202, the heater 203 is arranged on one side of the weight sensor 201, the heater 203 is arranged side by side with the semiconductor refrigeration piece 202, and also needs to be in full contact with the weight sensor 201. The heater 203 can be a heating wire that generates heat when powered.

[0063] Specifically, the controller is configured to start the heater when the real-time temperature is lower than a preset low-temperature threshold, and to turn off the heater 203 when the real-time temperature reaches the low-temperature threshold.

[0064] Exemplarily, referring to Figure 9 , Figure 9 is a second working flowchart of the controller provided by the embodiment of the present application, and the controller is configured to perform steps S21-S26. Considering that the weight sensor 201 will be in a too-low-temperature environment when the temperature in the storage compartment is too low, and that the real-time temperature being lower than a low-temperature threshold will also affect the detection result of the weight sensor 201, the heater 203 is started when the real-time temperature detected by the temperature sensor is lower than a preset low-temperature threshold, the heater 203 starts heating after being powered, which will increase the temperature around the weight sensor 201, and the heater is turned off when it is detected that the real-time temperature is higher than the low-temperature threshold.

[0065] In the embodiment of the present application, when it is detected that the temperature of the weight sensor 201 is too low, the heater 203 is started in time to lower the temperature, so that the temperature of the environment in which the weight sensor 201 is located cannot be too low, and the accuracy of the detection data of the weight sensor 201 is improved.

[0066] Compared with the prior art, the refrigerator disclosed by the present application, for the refrigerator provided with the weight sensor on the door shelf, the temperature adjusting component is arranged around the weight sensor, the temperature adjusting component can avoid that the temperature of the weight sensor changes obviously, the temperature environment of the sensor is stable, and thus the measurement accuracy of the weighing sensor is improved.

[0067] Referring to Figure 10 , Figure 10 is a flowchart of a refrigerator control method according to an embodiment of the present application, the refrigerator comprising a weight sensor and a temperature adjusting component; wherein the weight sensor and the temperature adjusting component are both arranged in a door shelf of the refrigerator, the temperature adjusting component comprises a semiconductor refrigerating sheet, and the method comprises:

[0068] S1, acquiring a real-time temperature of an environment in which the weight sensor is located;

[0069] S2, when the real-time temperature is higher than a preset high temperature threshold, starting the semiconductor refrigerating sheet until the real-time temperature is lower than the high temperature threshold, and then stopping the semiconductor refrigerating sheet.

[0070] For example, different types of weight sensors have their optimal temperature ranges for working, so the optimal temperature range corresponding to the current type of weight sensor is written in the controller of the refrigerator in advance, the optimal temperature range is composed of a high temperature threshold and a low temperature threshold, and the high temperature threshold is higher than the low temperature threshold. The temperature sensor can be arranged close to the weight sensor, such as being attached to the weight sensor, for collecting the real-time temperature of the environment in which the weight sensor is located. When the user opens the refrigerator door, the temperature sensor can quickly perceive the temperature change. The real-time temperature detected by the temperature sensor is acquired, when the real-time temperature is higher than a preset high temperature threshold, the semiconductor refrigerating sheet is started, the semiconductor refrigerating sheet starts refrigeration after being powered on, so as to reduce the temperature around the weight sensor, and when the real-time temperature is lower than the high temperature threshold, the semiconductor refrigerating sheet is stopped.

[0071] In the embodiment of the present application, when it is detected that the temperature of the weight sensor is too high, the semiconductor refrigerating sheet is started in time to lower the temperature, so that the temperature of the environment in which the weight sensor is located cannot be too high, and the accuracy of the detection data of the weight sensor is improved.

[0072] Specifically, the temperature adjustment component further includes a heater, which is provided on one side of the weight sensor and connected to a controller of the refrigerator; then, the method further includes:

[0073] S3. When the real-time temperature is lower than a preset low temperature threshold, start the heater, and when the real-time temperature reaches the low temperature threshold, turn off the heater.

[0074] For example, considering that when the temperature in the storage room is too low, the weight sensor will be in an environment with too low a temperature. Once the real-time temperature is lower than the low temperature threshold, it will also affect the detection result of the weight sensor. Therefore, after obtaining the real-time temperature detected by the temperature sensor, when the real-time temperature is lower than the preset low temperature threshold, the heater is started. After the heater is powered on, it starts to heat, which will increase the temperature around the weight sensor until it is detected that the real-time temperature is higher than the low temperature threshold, and then the heater is turned off.

[0075] In an embodiment of the present invention, when it is detected that the temperature of the weight sensor is too low, the heater is started in time to cool it down, which can ensure that the temperature of the environment where the weight sensor is located is not too low, thereby improving the accuracy of the weight sensor detection data.

[0076] It is worth noting that the working process of the refrigerator control method described in the embodiment of the present invention can refer to the working process of the controller in the refrigerator described in the above embodiment, and will not be repeated here.

[0077] Compared with the existing technology, the refrigerator control method disclosed in the present invention is aimed at refrigerators with weight sensors on the door shelves. By arranging a temperature control component around the weight sensor, the temperature control component can avoid obvious temperature changes of the weight sensor, achieve a stable sensor temperature environment, and thus improve the measurement accuracy of the weighing sensor.

[0078] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
