[0002] Refrigerators are commonly used by household users. The temperature inside the refrigerator varies greatly depending on the user's adjustment, resulting in large differences in the temperature of each compartment. However, each compartment uses the same temperature collector, which uses a voltage divider resistor to collect the temperature sensing resistor voltage, and judge the current resistance value of the temperature sensing resistor by the voltage, and judge the current temperature by the resistance. The smaller the difference between the resistance value of the temperature sensing resistor and the voltage divider resistor, the more accurate the collection result. However, using the same temperature collector for temperature collection in all compartments has certain limitations, and it is impossible to accurately measure the temperature of different compartments.

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0042] In one embodiment, the temperature collection method is applied to a refrigerator device, which includes a plurality of compartments and a temperature collection device, wherein a temperature collector is disposed in each compartment, and the temperature collection device is used to control the collection mode of each temperature collector.

[0043] Reference Figure 1The temperature collector includes a voltage divider circuit 110, a collection chip 130 and a thermistor 120. The voltage divider circuit 110 includes a plurality of voltage divider branches connected in parallel. The first end of the voltage divider circuit 110 is connected to a power supply, and the second end of the voltage divider circuit 110 is respectively connected to the collection chip 130 and the first end of the thermistor 120. The second end of the thermistor 120 is grounded. Each of the voltage divider branches is used to correspond to different temperature collection accuracies in different on-off states.

[0044] Specifically, the thermistor 120 in the temperature collector is used to sense the compartment temperature and generate resistance changes and voltage changes accordingly. The acquisition chip 130 converts the resistance changes and voltage changes of the thermistor 120 into corresponding temperature signals and outputs them to the temperature acquisition device.

[0045] When the temperature collector is in working state, the smaller the difference between the resistance of the voltage divider circuit 110 and the resistance of thermistor 120, the more accurate the temperature collection accuracy. However, the resistance of thermistor 120 changes greatly according to the change of the room temperature. Generally, the higher the room temperature, the smaller the resistance. Therefore, it is necessary to dynamically adjust the on-off state of each voltage divider branch in combination with the room temperature of the temperature collector to reduce the difference between the resistance of the voltage divider circuit 110 and the resistance of thermistor 120 at the room temperature. The ratio between the collected voltage of the temperature collector and the voltage difference is equal to the ratio between the resistance of thermistor 120 and the resistance of the voltage divider circuit 110. The voltage difference is the difference between the power supply voltage and the collected voltage, that is, V / (V0-V)=R 热 / R 分 , where V0 is the power supply voltage, V is the acquisition voltage, R 热 is the resistance of thermistor 120, R 分 is the resistance of the voltage divider circuit 110. When the resistance of the thermistor 120 changes due to the change of the compartment temperature based on the ratio relationship, the resistance of the voltage divider circuit 110 needs to be adjusted accordingly. Specifically, the resistance of the voltage divider circuit 110 is changed by changing the on-off state of each voltage divider branch in the voltage divider circuit 110 to adapt to the temperature collection environment of the compartment where the temperature collector is located, thereby improving the collection accuracy of the compartment temperature by the temperature collector.

[0046] In one embodiment, referring to Figure 2 The voltage-dividing circuit 110 includes a first voltage-dividing branch, a second voltage-dividing branch and a third voltage-dividing branch. The first voltage-dividing branch includes a first switch and a first voltage-dividing resistor connected in series. The second voltage-dividing branch includes a second switch and a second voltage-dividing resistor connected in series. The third voltage-dividing branch includes a third switch and a third voltage-dividing resistor connected in series. The resistance value of the first voltage-dividing resistor is greater than the resistance value of the second voltage-dividing resistor, and the resistance value of the second voltage-dividing resistor is greater than the resistance value of the third voltage-dividing resistor.

[0047] Specifically, the voltage-dividing circuit 110 includes three voltage-dividing branches connected in parallel, each of which is formed by a switch and a voltage-dividing resistor in series, but the resistance values ​​of the voltage-dividing resistors in different voltage-dividing branches are different. The switch is used to control the on-off state of the voltage-dividing branch. When the switch is in a closed state, the voltage-dividing branch where the switch is located is in an on state, and when the switch is in an open state, the voltage-dividing branch where the switch is located is in an off state. The resistance value of the voltage-dividing circuit 110 is determined by the resistance value of the voltage-dividing resistor in the voltage-dividing branch that is in an on state.

[0048] The first switch is denoted as K1, the second switch is denoted as K2, the third switch is denoted as K3, the first voltage-dividing resistor is denoted as R1, the second voltage-dividing resistor is denoted as R2, and the third voltage-dividing resistor is denoted as R3, R1>R2>R3, as the temperature of the compartment in the compartment gradually decreases, the resistance of the thermistor 120 will gradually increase, and accordingly, the resistance of the voltage-dividing circuit 110 needs to be gradually increased, so the resistance of the voltage-dividing circuit 110 can be changed by changing the switch states of the third switch, the second switch, and the first switch, so as to dynamically adjust the resistance of the voltage-dividing circuit 110 as the compartment temperature changes, so as to ensure the temperature acquisition accuracy in different temperature acquisition scenarios.

[0049] In one embodiment, the resistance value of the first voltage-dividing resistor is a preset multiple of the resistance value of the second voltage-dividing resistor, and the resistance value of the second voltage-dividing resistor is a preset multiple of the resistance value of the third voltage-dividing resistor.

[0050] Specifically, the preset multiple is N, that is, R1 = N * R2 = N 2 *R3, the preset multiple can be any positive integer, such as 2, 5, 10, etc., and is customized in combination with the temperature adjustment range of the refrigerator. In this embodiment, the preset multiple is 10, that is, R1=10R2=100R3, to ensure that there is a certain resistance span between different voltage-dividing resistors to adapt to a wider temperature adjustment range.

[0051] In one embodiment, Figure 2 A schematic diagram of a temperature acquisition method in an embodiment, referring to Figure 2 , provides a temperature collection method. This embodiment mainly applies this method to the above Figure 1 Taking the temperature collection device in the example as an example, the temperature collection method specifically includes the following steps:

[0052] Step S210, obtaining the set temperature of the target compartment where the target temperature collector is located, wherein the target compartment is a compartment in the refrigerator device where temperature collection is required.

[0053] Specifically, the target temperature collector is a temperature collector set in the target compartment. The target compartment is any compartment in the refrigerator device, which can be a refrigeration compartment, a freezing compartment, a fresh-keeping compartment, an ice-making compartment, etc. Different compartments correspond to different set temperatures. The set temperature is used to determine the ambient temperature of the compartment, that is, the compartment is refrigerated according to the set temperature, so the set temperature can be used to reflect the ambient temperature of the compartment.

[0054] Step S220, according to the temperature collection scene to which the set temperature of the target compartment belongs, determining the target collection mode currently used by the target temperature collector from multiple collection modes, wherein the target temperature collector in different collection modes is used to cope with different temperature collection scenes.

[0055] Specifically, when the set temperature of the compartment is determined, the resistance value of the thermistor 120 in the target temperature collector at the set temperature can be determined, and then the resistance value of the voltage divider circuit 110 in the target temperature collector at the set temperature can be selected, that is, the target temperature collector is determined to be in a target acquisition mode when the target compartment is at the set temperature. The target temperature collector can accurately collect the compartment temperature of the target compartment at the set temperature in the target acquisition mode, that is, the target temperature collector responds to different temperature acquisition scenarios in different acquisition modes to ensure the temperature acquisition accuracy in different temperature acquisition scenarios. Different temperature acquisition scenarios mean different set temperatures of the compartments.

[0056] Step S230, obtaining the target compartment temperature collected by the target temperature collector according to the target collection mode.

[0057] Specifically, the target temperature collector is controlled to work in the target collection mode, that is, the on-off states of different voltage-dividing branches in the target temperature collector are determined. Different collection modes correspond to different on-off states of each voltage-dividing branch, so as to determine that the voltage-dividing circuit 110 in the target temperature collector corresponds to different resistance values, which are used to adapt the resistance value of the thermistor 120 in the target temperature collector under different temperature collection scenarios, thereby ensuring the temperature collection accuracy of the target temperature collector under different temperature collection scenarios.

[0058] The temperature acquisition device obtains the target compartment temperature acquired by the target temperature collector according to the target acquisition mode. Since the resistance of the voltage divider circuit 110 matches the resistance of the thermistor 120 at the set temperature when the target temperature collector works according to the target acquisition mode, the target temperature collector can accurately feedback the target compartment temperature at this time, that is, the accuracy of the target compartment temperature is high.

[0059] The target collection mode of the target temperature collector is set based on the set temperature of the target compartment where the target temperature collector is located, so as to dynamically adjust the temperature collection accuracy of the target temperature collector, so that the temperature collection accuracy of the target temperature collector is adapted to the set temperature of the target compartment, ensuring that the target temperature collector can accurately collect the compartment temperature of the target compartment, thereby solving the problem that the existing temperature collector cannot accurately measure the compartment temperature of different compartments.

[0060] In one embodiment, the target acquisition mode currently used by the target temperature collector is determined from a plurality of acquisition modes according to the temperature acquisition scenario to which the set temperature of the target compartment belongs, including at least one of the following:

[0061] When the set temperature of the target compartment belongs to the first temperature range, determining the first acquisition mode as the target acquisition mode of the target temperature collector, wherein in the first acquisition mode, only the first voltage-dividing resistor is enabled in the target temperature collector;

[0062] When the set temperature of the target compartment belongs to the second temperature range, the second acquisition mode is determined as the target acquisition mode of the target temperature collector, wherein the lower threshold limit of the second temperature range is higher than the upper threshold limit of the first temperature range, and in the second acquisition mode, the target temperature collector respectively enables the first voltage divider resistor and the second voltage divider resistor;

[0063] When the set temperature of the target compartment belongs to the third temperature range, the third acquisition mode is determined as the target acquisition mode of the target temperature collector, wherein the lower threshold of the third temperature range is higher than the upper threshold of the second temperature range, and in the third acquisition mode, only the second voltage-dividing resistor is enabled in the target temperature collector;

[0064] When the set temperature of the target compartment belongs to a fourth temperature range, the fourth acquisition mode is determined as the target acquisition mode of the target temperature collector, wherein the lower threshold limit of the fourth temperature range is higher than the upper threshold limit of the third temperature range, and the target temperature collector enables the second voltage-dividing resistor and the third voltage-dividing resistor respectively in the fourth acquisition mode;

[0065] When the set temperature of the target compartment belongs to the fifth temperature range, the fifth acquisition mode is determined as the target acquisition mode of the target temperature collector, wherein the lower threshold limit of the fifth temperature range is higher than the upper threshold limit of the fourth temperature range, and in the fifth acquisition mode, only the third voltage-dividing resistor is enabled in the target temperature collector, the resistance value of the first voltage-dividing resistor and the resistance value of the second voltage-dividing resistor are preset multiples, and the resistance value of the second voltage-dividing resistor and the resistance value of the third voltage-dividing resistor are preset multiples.

[0066] Specifically, the first temperature range is denoted as T1, the second temperature range is denoted as T2, the third temperature range is denoted as T3, the fourth temperature range is denoted as T4, and the fifth temperature range is denoted as T5, where T1 < T2 < T3 < T4 < T5. In this embodiment, the first temperature range is set as the temperature range less than -25°C, the second temperature range is (-15°C to -25°C), the third temperature range is (5°C to -15°C), the fourth temperature range is (5°C to 15°C), and the fifth temperature range is the temperature range greater than 15°C.

[0067] When the set temperature of the target compartment is within the first temperature range, it indicates that the target compartment is a super-freezing compartment, belonging to the first temperature acquisition scenario. At this time, the thermistor 120 in the target temperature collector has a large resistance due to the low temperature. At this time, it is necessary to make the resistance of the voltage division circuit 110 as large as possible. Then only the first voltage division resistor with the largest resistance is enabled, that is, the thermistor 120 is voltage-divided only through the first voltage division branch to collect the compartment temperature. The first acquisition mode that only enables the first voltage division resistor is determined as the target acquisition mode of the target temperature collector in this temperature acquisition scenario to adapt to the thermistor 120 with a large resistance, so as to ensure the temperature acquisition accuracy of the target temperature collector in this temperature acquisition scenario.

[0068] When the set temperature of the target compartment is within the second temperature range, it indicates that the target compartment is a freezing compartment, belonging to the second temperature acquisition scenario. At this time, the thermistor 120 in the target temperature collector has a large resistance due to the low temperature, but the resistance of the thermistor 120 in this second temperature acquisition scenario is smaller than that in the first temperature acquisition scenario. At this time, the first voltage division resistor and the second voltage division resistor are enabled respectively. That is, first, the first voltage division branch is enabled to voltage-divide the thermistor 120 to collect the first compartment temperature, and then after turning off the first voltage division branch and enabling the second voltage division branch to voltage-divide the thermistor 120 to collect the second compartment temperature, the average value of the first compartment temperature and the second compartment temperature is used as the final target compartment temperature of the target temperature collector, so as to ensure the temperature acquisition accuracy of the target temperature collector in this temperature acquisition scenario.

[0069] When the set temperature of the target compartment is within the third temperature range, it indicates that the target compartment belongs to the third temperature acquisition scenario. At this time, the thermistor 120 in the target temperature collector has a larger resistance value due to the lower temperature, but the resistance value of the thermistor 120 in this third temperature acquisition scenario is less than the resistance value of the thermistor 120 in the second temperature acquisition scenario. At this time, only the second voltage-dividing resistor is enabled, that is, the thermistor 120 is divided by the second voltage-dividing branch to collect the compartment temperature. The third acquisition mode in which only the second voltage-dividing resistor is enabled is determined as the target acquisition mode of the target temperature collector in the temperature acquisition scenario to adapt to the resistance value of the thermistor 120 in the temperature acquisition scenario, thereby ensuring the temperature acquisition accuracy of the target temperature collector in the temperature acquisition scenario.

[0070] When the set temperature of the target compartment is within the fourth temperature range, it indicates that the target compartment is a cold storage compartment, which belongs to the fourth temperature acquisition scenario. The resistance value of the thermistor 120 in the fourth temperature acquisition scenario is less than the resistance value of the thermistor 120 in the third temperature acquisition scenario. At this time, the second voltage divider resistor and the third voltage divider resistor are respectively enabled, that is, the second voltage divider branch is first enabled to divide the voltage of the thermistor 120 to obtain the second compartment temperature, and then the second voltage divider branch is turned off and the third voltage divider branch is enabled to divide the voltage of the thermistor 120 to obtain the third compartment temperature, and the average value of the second compartment temperature and the third compartment temperature is used as the final target compartment temperature of the target temperature collector, thereby ensuring the temperature acquisition accuracy of the target temperature collector in this temperature acquisition scenario.

[0071] When the set temperature of the target compartment is within the fifth temperature range, it indicates that the target compartment belongs to the fifth temperature acquisition scenario. The thermistor 120 in the target temperature collector has a small resistance value due to the high temperature. At this time, it is necessary to make the resistance value of the voltage divider circuit 110 as small as possible. Then, only the third voltage divider resistor with the smallest resistance value is enabled, that is, the thermistor 120 is divided by the third voltage divider branch to collect the compartment temperature. The fifth acquisition mode in which only the third voltage divider resistor is enabled is determined as the target acquisition mode of the target temperature collector in the temperature acquisition scenario to adapt to the resistance value of the thermistor 120 in the temperature acquisition scenario, thereby ensuring the temperature acquisition accuracy of the target temperature collector in the temperature acquisition scenario.

[0072] In one embodiment, in the first acquisition mode, only the first voltage-dividing resistor is enabled in the target temperature collector; in the second acquisition mode, only the first voltage-dividing resistor and the second voltage-dividing resistor are enabled in the target temperature collector, at which time the first voltage-dividing resistor and the second voltage-dividing resistor are enabled at the same time and in parallel, and the resistance value of the voltage-dividing circuit 110 is the parallel resistance value of the first voltage-dividing resistor and the second voltage-dividing resistor; in the third acquisition mode, only the second voltage-dividing resistor is enabled in the target temperature collector; in the fourth acquisition mode, only the second voltage-dividing resistor and the third voltage-dividing resistor are enabled in the target temperature collector, at which time the second voltage-dividing resistor and the third voltage-dividing resistor are enabled at the same time and in parallel, and the resistance value of the voltage-dividing circuit 110 is the parallel resistance value of the second voltage-dividing resistor and the third voltage-dividing resistor; in the fifth acquisition mode, only the third voltage-dividing resistor is enabled in the target temperature collector.

[0073] That is, the resistance of the voltage divider circuit 110 is dynamically adjusted to cope with the resistance change of the thermistor 120 in different temperature acquisition scenarios, so as to improve the temperature acquisition accuracy.

[0074] In one embodiment, the step of obtaining the target compartment temperature collected by the target temperature collector according to the target collection mode includes at least one of the following:

[0075] When the target acquisition mode is the first acquisition mode, the first compartment temperature acquired by the target temperature collector when only the first voltage divider branch is turned on is used as the target compartment temperature;

[0076] When the target acquisition mode is the second acquisition mode, the average of the first compartment temperature acquired by the target temperature collector when only the first voltage-dividing branch is turned on and the second compartment temperature acquired by the target temperature collector when only the second voltage-dividing branch is turned on is determined as the target compartment temperature;

[0077] When the target acquisition mode is the third acquisition mode, the second compartment temperature acquired by the target temperature collector when only the second voltage-dividing branch is turned on is used as the target compartment temperature;

[0078] When the target acquisition mode is the fourth acquisition mode, the average of the second compartment temperature acquired by the target temperature collector when only the second voltage-dividing branch is turned on and the third compartment temperature acquired by the target temperature collector when only the third voltage-dividing branch is turned on is determined as the target compartment temperature;

[0079] When the target acquisition mode is the fifth acquisition mode, the third compartment temperature acquired by the target temperature collector when only the third voltage-dividing branch is turned on is used as the target compartment temperature.

[0080] Specifically, when the target acquisition mode is the first acquisition mode, the target temperature collector only conducts the first voltage dividing branch, that is, the first voltage dividing resistor is used to divide the voltage of the thermistor 120. At this time, the first compartment temperature collected is the target compartment temperature.

[0081] When the target acquisition mode is the second acquisition mode, the target temperature collector uses the first voltage-dividing branch and the second voltage-dividing branch to divide the thermistor 120 to respectively acquire the first compartment temperature and the second compartment temperature, that is, the target temperature collector uses one voltage-dividing resistor each time, but the greater the difference between the resistance value of the voltage-dividing resistor and the resistance value of the thermistor 120, the greater the temperature acquisition error will be. Therefore, the average value of the compartment temperatures acquired by conducting different voltage-dividing branches is combined to reduce the acquisition error, that is, the average value of the first compartment temperature and the second compartment temperature is taken as the final target compartment temperature in the second acquisition mode to reduce the acquisition error of a single voltage-dividing branch.

[0082] When the target acquisition mode is the third acquisition mode, the target temperature collector only conducts the second voltage dividing branch, that is, the second voltage dividing resistor is used to divide the voltage of the thermistor 120. At this time, the collected second compartment temperature is the target compartment temperature.

[0083] When the target acquisition mode is the fourth acquisition mode, the target temperature collector uses the second voltage-dividing branch and the third voltage-dividing branch to divide the thermistor 120 to respectively acquire the second compartment temperature and the third compartment temperature, that is, the target temperature collector uses one voltage-dividing resistor each time, but the greater the difference between the resistance value of the voltage-dividing resistor and the resistance value of the thermistor 120, the greater the temperature acquisition error will be. Therefore, the average value of the compartment temperatures acquired by conducting different voltage-dividing branches is combined to reduce the acquisition error, that is, the average value of the second compartment temperature and the third compartment temperature is taken as the final target compartment temperature in the fourth acquisition mode to reduce the acquisition error of a single voltage-dividing branch.

[0084] When the target acquisition mode is the fifth acquisition mode, the target temperature collector only conducts the third voltage-dividing branch, that is, the third voltage-dividing resistor is used to divide the voltage of the thermistor 120. At this time, the third compartment temperature collected is the target compartment temperature.
