Description

Technical Field

[0001] The present invention relates to the technical field of refrigerators, and in particular to a refrigerator control method, a refrigerator, and a computer storage medium. Background Art

[0002] Currently, the market is dominated by air-cooled refrigerators. The condensing pipes of traditional air-cooled refrigerators are all routed from the side or back panel of the cabinet. When the heat dissipation temperature of the condensing pipe is high, the user's body will feel hot when touching the side of the refrigerator, which will lead to poor user experience. In severe cases, children may be scalded, which is easy to cause user complaints. In addition, the reserved space of existing home refrigerators is small. In this case, the side and back panels of the refrigerator cannot ensure sufficient heat dissipation gap, resulting in insufficient heat dissipation from the condenser and abnormal refrigerator cooling. To address these problems, manufacturers of high-end products will choose to place the condenser in the compressor compartment at the bottom of the refrigerator. However, the space in the compressor compartment is small and has two major heat dissipation components, the compressor and condenser. Due to insufficient heat dissipation, the fan in the compressor compartment may melt and deform, and the fan may become blocked, causing abnormal heat dissipation from the condenser and the refrigerator to stop cooling. Summary of the Invention

[0003] In order to solve the technical problem in the prior art that the temperature in the compressor compartment is too high causing fan stalling, the present invention provides a refrigerator control method, a refrigerator, and a computer storage medium.

[0004] The technical solution adopted in the present invention is:

[0005] The present invention provides a refrigerator control method, comprising the steps of:

[0006] detecting a compartment temperature of a compartment in which a compressor and a condenser of the refrigerator are installed;

[0007] Determine whether the compartment temperature is less than or equal to a first preset temperature; if not, adjust the refrigerator to a corresponding operating state to cool the compartment according to the extent to which the compartment temperature exceeds the first preset temperature; if so, control the refrigerator to operate according to normal control logic.

[0008] Furthermore, the step of adjusting the refrigerator to a corresponding operating state to cool the compartment according to the extent to which the compartment temperature exceeds the first preset temperature specifically includes the following steps: when the compartment temperature is greater than the first preset temperature, adjusting the compressor frequency to lower the compartment temperature.

[0009] Furthermore, after executing the step of adjusting the operating state of the compressor to lower the compartment temperature, it is determined whether the compartment temperature is less than or equal to a second preset temperature, and the second preset temperature is greater than the first preset temperature; if not, the compressor stops running for a preset time, and the start and stop temperatures of the refrigerator and freezer are raised to a preset temperature; if so, return to the step of adjusting the compressor frequency to lower the compartment temperature.

[0010] Furthermore, after executing the steps of stopping the compressor for a preset time and raising the start and stop temperatures of the refrigerator and freezer compartments to a preset temperature, it is determined whether the compartment temperature is less than or equal to a third preset temperature, and the third preset temperature is greater than the second preset temperature. If not, the compressor is forced to stop, the condensing fan is operated, and the process returns to the step of determining whether the compartment temperature is less than or equal to the first preset temperature; if so, the process returns to the step of determining whether the compartment temperature is less than or equal to the second preset temperature.

[0011] Furthermore, when the refrigerator is controlled to operate according to normal control logic, it is detected whether the condensing fan of the condenser rotates normally; if so, the refrigerator returns to the operation step according to normal control logic; if not, the compressor is forced to stop and the condensing fan is powered off.

[0012] Furthermore, the compressor is forced to stop, and after the condensing fan is powered off, the display board reports a fault, the buzzer works intermittently, and the display board displays the real-time temperature of each compartment.

[0013] Furthermore, after executing the steps of forced shutdown of the compressor and power off of the condensing fan, it is determined whether the temperature of the refrigerating chamber is higher than the preset refrigeration temperature. If so, the refrigerating damper is opened and the freezing fan is operated; if not, the refrigerating damper is closed.

[0014] Furthermore, after executing the steps of opening the refrigeration damper and running the freezing fan, determine whether the freezer compartment temperature is greater than or equal to a fourth preset temperature; if so, close the refrigeration damper; if not, return to the step of determining whether the refrigeration compartment temperature is higher than the preset refrigeration temperature.

[0015] The present invention also provides a refrigerator that uses the above refrigerator control method to cool the compartment.

[0016] Furthermore, the refrigerator includes: a stall sensor for detecting whether the condensing fan rotates normally, and a temperature sensor for detecting the temperature of the compartment.

[0017] The present invention also provides a computer storage medium for storing a computer program, wherein the computer program executes the above-mentioned refrigerator control method when running.

[0018] Compared with the prior art, the present invention adjusts the refrigerator to different operating states to cool the compartment by judging whether the compartment temperature exceeds the first preset temperature, and by setting a stall sensor, it can detect whether the condensing fan is stalled. If the condensing fan is stalled, the compressor will be forced to stop and the condensing fan will be powered off, preventing the compartment temperature from continuing to rise without the heat dissipation of the condensing fan. It also prevents the condensing fan from being damaged by remaining in operation after being blocked. In order to slowly raise the temperature in the refrigerator after stalling, the system can also adjust the refrigeration damper to control the temperature of different compartments in the refrigerator, which solves the problem that the existing technology has a small space in the compartment and has two major heat dissipation components, the compressor and the condenser. It is easy for the fan in the compressor chamber to melt and deform due to insufficient heat dissipation, and the fan is stalled, causing abnormal heat dissipation of the condenser and the refrigerator to fail to cool.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0027] Currently, the market is dominated by air-cooled refrigerators. The condensing pipes of traditional air-cooled refrigerators are all routed from the side or back panel of the cabinet. When the heat dissipation temperature of the condensing pipe is high, the user's body will feel hot when touching the side of the refrigerator, which will lead to poor user experience. In severe cases, children may be scalded, which is easy to cause user complaints. In addition, the reserved space of existing home refrigerators is small. In this case, the side and back panels of the refrigerator cannot ensure sufficient heat dissipation gap, resulting in insufficient heat dissipation from the condenser and abnormal refrigerator cooling. To address these problems, manufacturers of high-end products will choose to place the condenser in the compressor compartment at the bottom of the refrigerator. However, the space in the compressor compartment is small and has two major heat dissipation components, the compressor and condenser. Due to insufficient heat dissipation, the fan in the compressor compartment may melt and deform, and the fan may become blocked, causing abnormal heat dissipation from the condenser and the refrigerator to stop cooling. The present invention proposes a refrigerator control method, which detects the compartment temperature of the refrigerator compartment where the compressor and condenser are installed, and determines whether the compartment temperature is less than or equal to a first preset temperature. If not, the refrigerator is adjusted to a corresponding operating state to cool the compartment according to the extent to which the compartment temperature exceeds the first preset temperature. If so, the refrigerator is controlled to operate according to normal control logic.

[0028] like Figure 1 As shown, the present invention proposes a refrigerator control method, comprising the steps of:

[0029] Check the temperature of the refrigerator compartment where the compressor and condenser are installed;

[0030] Determine whether the compartment temperature is less than or equal to a first preset temperature; if not, adjust the refrigerator to a corresponding operating state to cool the compartment where the compressor and condenser are installed based on the extent to which the compartment temperature exceeds the first preset temperature; if so, control the refrigerator to operate according to normal control logic.

[0031] Specifically, the normal control logic of the refrigerator is that the refrigerator and freezer compartments operate according to the temperature set by the user, and the frequency of the compressor and the condensing fan operate according to the factory settings. The above-mentioned first preset temperature range is between 85-90 degrees Celsius. Preferably, the first preset temperature is 85 degrees Celsius. When it is judged that the compartment temperature is greater than the first preset temperature, it means that the compartment temperature is too high at this time. According to the extent that the compartment temperature exceeds the first preset value, the refrigerator is adjusted to different states to cool the compartment; when the judgment is established, that is, when the compartment temperature is less than or equal to the first preset temperature, it proves that the compartment temperature is within the "safe temperature" range (the safe temperature is less than or equal to the first preset temperature), and the program controls the refrigerator to operate according to the normal control logic.

[0032] In a first embodiment, adjusting the refrigerator to a corresponding operating state based on the extent to which the compartment temperature exceeds a first preset temperature to cool the compartment where the compressor and condenser are installed specifically includes the following steps: when the compartment temperature exceeds the first preset temperature, adjusting the compressor frequency to lower the compartment temperature. This is because when the compartment temperature exceeds the first preset temperature, it indicates that the compartment temperature where the compressor and condenser are installed is too high.

[0033] To adjust the compressor frequency, specifically: lower the compressor frequency by one level from the current gear. After the compressor frequency is reduced, the compressor power will also be lower. Because the compressor power is lower, the heat generated by the compressor will be reduced, so the temperature of the compartment where the compressor and condenser are installed will be lower.

[0034] For example, the compressor of the refrigerator used is a variable frequency compressor, and the compressor is controlled according to the S1-S7 gear. The S1 gear has the lowest compressor speed, the corresponding cooling capacity is also the smallest, and the compressor power is smaller; as the gear increases from S1 to S7, the cooling capacity gradually increases, and S7 reaches the set highest gear, and the cooling capacity is the largest, and the compressor power is also the largest. The increase in gear brings about an increase in the frequency of the compressor, resulting in an increase in power, which will also cause an increase in the heat generated by the compressor, driving the air temperature in the compartment to rise. When the compartment temperature is greater than or equal to the first preset temperature, it means that the temperature of the compartment where the compressor and condenser are installed is already too high. At this time, the compressor frequency is reduced, and the compressor frequency is adjusted to reduce the compartment temperature. The compressor frequency is reduced by one level. After the compressor frequency is reduced, the compressor power becomes lower. Because the compressor power is lowered, the heat generated by the compressor is reduced, so the temperature of the compartment where the compressor and condenser are installed will decrease. Therefore, in order to lower the temperature of the compartment where the compressor and condenser are installed, the compressor speed needs to be reduced. Every time the compressor speed needs to be reduced, the compressor gear is reduced by one level from the current speed gear, for example, from S7 gear to S6 gear.

[0035] In a second embodiment, the refrigerator is adjusted to a corresponding operating state based on the extent to which the compartment temperature exceeds a first preset temperature, thereby cooling the compartment where the compressor and condenser are installed. Specifically, the steps include: when the compartment temperature is greater than the first preset temperature, adjusting the compressor frequency to lower the compartment temperature. The compressor frequency is reduced to reduce compressor power and heat generation, thereby lowering the compartment temperature. Then, it is determined whether the compartment temperature is less than or equal to a second preset temperature. If not, it is confirmed that the compartment temperature is greater than the second preset temperature, and the compressor is stopped for a preset time. At the same time, the start and stop temperatures of the refrigerator and freezer compartments are raised by a preset temperature. If so, it is confirmed that the compartment temperature is less than or equal to the second preset temperature, and the process returns to the step of adjusting the compressor frequency to lower the compartment temperature, and the compartment temperature is again adjusted by decreasing the compressor frequency.

[0036] Specifically, the first preset temperature range is between 85-90°C, preferably, the first preset temperature range is 85°C, and the second preset temperature range is between 91-95°C, preferably, 95°C; the second preset temperature range is greater than the first preset temperature range; the compressor stop preset time range is between 25-35 minutes, preferably, the compressor stop time is 25 minutes; the start and stop temperatures of the refrigerator and freezer compartments are raised by a preset temperature, preferably, the preset temperature is 1°C; when the compartment temperature is greater than the first preset temperature, it indicates that the compartment temperature where the compressor and condenser are installed is too high. At this time, the compressor frequency is adjusted to reduce the compressor frequency. When the compressor frequency is reduced, the compressor power is reduced, so the heat generated by the compressor is reduced, and the temperature of the compartment where the compressor and condenser are installed will decrease. When the compartment temperature is greater than the first preset temperature, it is necessary to determine whether the compartment temperature is less than or equal to the second preset temperature, and the next step is executed based on the comparison result between the compartment temperature and the second preset temperature. If the compartment temperature is greater than the second preset temperature, it means that the compartment temperature is still too high after the frequency reduction, and the compressor needs to be stopped for a preset time. At the same time, the start and stop temperatures of the refrigerator and freezer are raised by 1°C to reduce the cooling capacity; if the compartment temperature is less than or equal to the second preset temperature, return to the step of adjusting the compressor frequency to reduce the compartment temperature; a temperature increase of 1°C will not have a significant impact on the items in the refrigerator and freezer, and at the same time ensure that the compressor stop time is not too long or too short.

[0037] like Figure 2 As shown, in the third embodiment:

[0038] The refrigerator is adjusted to a corresponding operating state based on the extent to which the compartment temperature exceeds a first preset temperature, thereby cooling the compartment where the compressor and condenser are installed. Specifically, the steps include: when the compartment temperature exceeds the first preset temperature, adjusting the compressor frequency to reduce the compartment temperature. After adjusting the compressor frequency to reduce the compartment temperature, it is then determined whether the compartment temperature is less than or equal to a second preset temperature. If not, it indicates that the compartment temperature is greater than the second preset temperature, the compressor is stopped for a preset time, and the start and stop temperatures of the refrigerator and freezer compartments are raised by a preset temperature. If so, it indicates that the compartment temperature is less than or equal to the second preset temperature, and the process returns to the step of reducing the compressor frequency to reduce the compartment temperature.

[0039] Furthermore, when the compartment temperature is greater than the second preset temperature, the compressor stops running for a preset time, and the start and stop temperatures of the refrigerator and freezer are raised to a preset temperature (the preset temperature can be set to 1°C, and a temperature increase of 1°C during the time when the compressor stops running will not cause excessive impact on the items in the refrigerator and freezer), it is determined whether the compartment temperature is less than or equal to the third preset temperature. If not, the compressor is forced to stop, the condensing fan is run, and the process returns to the step of determining whether the compartment temperature is less than or equal to the first preset temperature; if so, the process returns to the step of determining whether the compartment temperature is less than or equal to the second preset temperature.

[0040] Specifically, the third preset temperature range is 96-105°C, preferably, the third preset temperature is 100°C, and the value of the third preset temperature range is greater than the value of the second preset temperature range; when the compartment temperature is greater than the first preset temperature, it indicates that the compartment temperature is already too high. At this time, the compressor frequency is adjusted to reduce the compressor frequency. After the compressor frequency is reduced, the compressor power is reduced, so the heat generated by the compressor is reduced, and the temperature of the compartment where the compressor and condenser are installed will be reduced. When the compartment temperature of the compartment where the compressor and condenser are installed is greater than the first preset temperature, it is necessary to determine whether the compartment temperature is less than or equal to the second preset temperature, and the next step is executed based on the comparison result between the compartment temperature and the second preset temperature.

[0041] If the compartment temperature is greater than the second preset temperature, the compressor stops running for a preset time, and the start and stop temperatures of the refrigerator and freezer are raised by 1°C; if the compartment temperature is less than or equal to the second preset temperature, the process returns to the step of reducing the compressor frequency; when the compartment temperature is greater than the second preset temperature, the time when the compressor stops running, a temperature rise of 1°C will not cause too much impact on the items in the refrigerator and freezer. When the compressor stops running for a preset time, and the start and stop temperatures of the refrigerator and freezer are raised by a preset temperature, it is determined whether the compartment temperature is less than or equal to the third preset temperature. If the determination is true, it proves that the compartment temperature has not reached the "warning line" (the third preset temperature). At this time, the process returns to determine whether the compartment temperature is less than or equal to the second preset temperature. If the determination is false, it means that the compartment has reached the upper temperature limit set by the system. Here, in order to protect key refrigeration components such as the fan and ensure the safety of the refrigerator, the compressor is forced to stop, and the condensing fan continues to run to cool the compartment, and then the process returns to the step of determining whether the compartment temperature is less than or equal to the first preset temperature. After the compressor stops, it will no longer generate heat, preventing the temperature in the warehouse from continuing to rise at the source, and the condensing fan continues to work to speed up the heat dissipation in the warehouse.

[0042] Specifically, when the compartment temperature is less than or equal to the first preset temperature, the refrigerator is controlled to operate according to the normal control logic until it stops, and when operating according to the normal logic, it is detected whether the condensing fan of the condenser is rotating normally; if so, it proves that the condensing fan can operate normally and no additional control is required, and the refrigerator returns to the normal logic operation steps; if not, it proves that the condensing fan has been blocked, and the compressor is forced to stop to prevent the compressor from continuing to work and generating heat. The condensing fan has been blocked and cannot dissipate heat to the compartment, causing the temperature in the compartment to continue to rise; the condensing fan is powered off to prevent the condensing fan from continuing to run and burning out when it is blocked.

[0043] In a further embodiment, when the compressor is forced to shut down and the condenser fan is powered off, a fault message is displayed on the display panel, a buzzer sounds intermittently, and the display panel shows the real-time temperature of each compartment. During periods when the refrigerator is not cooling, users can monitor temperature changes in real time, allowing them to assess the condition and implement emergency measures promptly.

[0044] Specifically, after the compressor stops and the condensing fan is powered off, the display panel shows a fault and the buzzer sounds intermittently, reminding the user that the refrigerator has failed. The real-time temperature of each compartment displayed on the display panel includes the temperature of the refrigerator compartment and the temperature of the freezer compartment.

[0045] In a further embodiment, it is determined whether the refrigeration chamber has a cooling demand, that is, whether the temperature of the refrigeration chamber is greater than a preset refrigeration temperature. If so, the refrigeration damper is opened and the freezing fan is operated; if not, the refrigeration damper is closed.

[0046] Specifically, if the refrigerator compartment temperature is lower than the preset refrigeration temperature, the refrigeration damper opens and the freezer fan runs. Because the refrigerator compartment temperature is higher than the freezer compartment temperature and users frequently open and close the refrigerator compartment door, the refrigerator compartment temperature rises quickly. In this case, the fan runs to transfer the cold air from the freezer compartment to the refrigerator compartment, delaying the temperature rise. If the refrigerator compartment temperature is lower than the preset refrigeration temperature, the refrigeration damper remains closed, and the cold air from the freezer compartment does not need to be transferred to the refrigerator compartment.

[0047] In a further embodiment, after the refrigeration damper is opened and the freezing fan is running, it is determined whether the freezer compartment temperature is greater than or equal to a fourth preset temperature (d); if so, the refrigeration damper is closed; if not, the process returns to the step of determining whether the refrigeration compartment has a cooling demand.

[0048] Specifically, the fourth preset temperature (d) ranges from -10°C to -12°C, preferably, -10°C. If the freezer compartment temperature is determined to be greater than or equal to the fourth preset temperature, it indicates that the freezer compartment temperature has not reached the preset freezer compartment temperature (the fourth preset temperature). To prevent frozen food from thawing, the refrigeration damper is forcibly closed to ensure that the freezer compartment temperature is within a certain range, ensuring normal operation of the freezer compartment and preventing food from thawing. If the freezer compartment temperature is not greater than or equal to the freezer compartment temperature, the process returns to the step of determining whether there is a cooling demand for the refrigeration compartment.

[0049] The present invention also provides a refrigerator using the above refrigerator control method.

[0050] like Figure 3 and Figure 4 As shown, in a specific embodiment, refrigerator 5 includes: compressor 2, condenser 3, evaporator, condenser fan 1, stall sensor, and temperature sensor 4. Compressor 2, condenser 3, and condenser fan 1 are installed in a compartment at the bottom of the refrigerator. The evaporator is used to connect the air duct between the refrigerator and freezer compartments to deliver cold air for refrigeration. The stall sensor is installed on condenser fan 1. When condenser fan 1 stalls, the stall sensor detects that condenser fan 1 is not rotating and sends a stall signal to the system to determine whether condenser fan 1 is rotating normally. Upon receiving the stall signal from the stall sensor, the system forcibly shuts down compressor 2 and powers off condenser fan 1. A temperature sensor is installed in the compartment to monitor the temperature within the compartment.

[0051] The present invention also provides a computer storage medium for storing a computer program, wherein the computer program executes the above-mentioned refrigerator control method when running.

[0052] In one or more exemplary embodiments, the functions described may be implemented in hardware, software, firmware, or any combination thereof. If implemented in software as a computer program product, the functions may be stored on or transmitted via a computer-readable medium as one or more instructions or codes. Computer-readable media include both computer storage media and communication media, including any media that facilitates the transfer of a computer program from one location to another. A storage medium may be any available medium that can be accessed by a computer.

Any connection is also properly referred to as a computer-readable medium. For example, if the software is transmitted from a website, server, or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwaves, then the coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwaves are included in the definition of medium.

To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.

[0054] The present invention adjusts the refrigerator to different operating states to cool the compartment by judging whether the compartment temperature exceeds the first preset temperature, and by setting a stall sensor, it can detect whether the condensing fan is stalled. If the condensing fan is stalled, the compressor will be forced to stop and the condensing fan will be powered off, preventing the compartment temperature from continuing to rise in the absence of heat dissipation from the condensing fan, and also preventing the condensing fan from being damaged by remaining in operation after being blocked. In order to slowly raise the temperature in the refrigerator after stalling, the system can also adjust the refrigeration damper to control the temperature of different compartments in the refrigerator, solving the problem that the existing technology has a small space in the compartment and has two major heat dissipation components, the compressor and the condenser, which is prone to melting and deformation of the compressor room fan due to insufficient heat dissipation, and the fan is stalled, causing abnormal heat dissipation of the condenser and the refrigerator not cooling.
