[0043] Figure 3 1 is a flowchart of a refrigerator control method according to the first and second embodiments of the present invention. DETAILED DESCRIPTION

[0044] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0045] The refrigeration device of the present invention may be a refrigerator, a freezer or a commercial display cabinet, etc. The specific implementation of the present invention will be described below by taking a refrigerator as an example.

[0046] The first embodiment of the present invention is as follows:

[0047] Reference Figure 1 In this embodiment, the refrigerator 100 includes a body 1, a storage chamber formed in the body 1, and a refrigeration system for supplying cold to the storage chamber.

[0048] The refrigeration system may include a compressor, a condenser, a throttle valve and an evaporator, which are connected in sequence by a refrigerant pipeline to form a closed system. The refrigerant circulates continuously in the refrigeration system, changes state, and exchanges heat with the outside world. After the liquid refrigerant absorbs the heat of the object to be cooled in the evaporator, it vaporizes into low-temperature and low-pressure steam, is sucked into the compressor, compressed into high-pressure and high-temperature steam, and then discharged into the condenser, releases heat in the condenser, condenses into high-pressure liquid, is throttled by the throttle valve to low-pressure and low-temperature refrigerant, and enters the evaporator again to absorb heat and vaporize, thus realizing the refrigeration cycle.

[0049] The storage room includes a refrigerating room 2 and a temperature-changing room 7. The temperature-changing room 7 can be arranged below the refrigerating room 2.

[0050] The refrigerator 100 further includes a potentiometer knob 5, a refrigeration temperature sensor 6 disposed in the refrigeration chamber 2, and a variable temperature sensor 10 disposed in the variable temperature chamber 7. The refrigeration temperature sensor 6 is used to detect the temperature of the refrigeration chamber 2. The variable temperature sensor 10 is used to detect the temperature of the variable temperature chamber 7.

[0051] The refrigerator 100 includes a refrigeration door for opening and closing the refrigeration chamber 2. The potentiometer knob 5 can be arranged outside the refrigeration door for the convenience of the user to rotate. The number of the potentiometer knob 5 can be set to only one, and the temperature of multiple storage chambers of the refrigerator 100 can be controlled by one potentiometer knob 5 to reduce costs.

[0052] The potentiometer knob 5 is an adjustable electronic component, which can be composed of a resistor and a rotatable knob. The resistor includes a fixed contact and a moving contact. By rotating the knob to change the position of the moving contact on the resistor, the resistance value between the moving contact and the fixed contact can be changed, thereby changing the voltage and current output by the potentiometer knob 5.

[0053] The refrigerator 100 also includes a memory and a processor. The memory stores a computer program that can be run on the processor. When the processor executes the computer program, the steps in the control method of the refrigerator 100 of the present invention are implemented.

[0054] Reference Figure 3 In this embodiment, the control method of the refrigerator 100 includes:

[0055] Acquire an electrical signal of a potentiometer knob 5 of the refrigerator 100;

[0056] The refrigeration temperature of the refrigeration chamber 2 and the variable temperature temperature of the variable temperature chamber 7 of the refrigerator 100 are obtained according to the electrical signal of the potentiometer knob 5;

[0057] Detecting the temperatures of the refrigerating chamber 2 and the temperature-changing chamber 7;

[0058] Controlling the refrigeration system of the refrigerator 100 to supply cold to the cold storage chamber 2 according to the temperature of the cold storage chamber 2 and the cold storage supply temperature;

[0059] The cooling system is controlled to supply cooling to the variable temperature chamber 7 according to the temperature of the variable temperature chamber 7 and the variable temperature cooling temperature.

[0060] The refrigeration supply temperature may include a refrigeration supply start temperature and a refrigeration supply stop temperature. When the temperature of the refrigeration chamber 2 reaches the refrigeration supply start temperature, the refrigeration system is controlled to start supplying cold to the refrigeration chamber 2; when the temperature of the refrigeration chamber 2 reaches the refrigeration supply stop temperature, the refrigeration system is controlled to stop supplying cold to the refrigeration chamber 2.

[0061] The variable temperature cooling temperature may include a variable temperature cooling start temperature and a variable temperature cooling stop temperature. When the temperature of the variable temperature chamber 7 reaches the variable temperature cooling start temperature, the refrigeration system is controlled to start supplying cooling to the variable temperature chamber 7. When the temperature of the variable temperature chamber 7 reaches the variable temperature cooling stop temperature, the refrigeration system is controlled to stop supplying cooling to the variable temperature chamber 7.

[0062] The information related to the correspondence between different electrical signals of the potentiometer knob 5 and the refrigerated cooling temperature and the variable temperature cooling temperature can be preset by the R&D personnel and stored in the memory of the refrigerator 100.

[0063] With such an arrangement, it is possible to simultaneously control the temperatures of the refrigerating chamber 2 and the variable temperature chamber 7 by means of one mechanical thermostat, namely one potentiometer knob 5, thereby reducing the cost of the refrigeration equipment.

[0064] In this embodiment, the electrical signal is a voltage signal, and the voltage signal changes as the potentiometer knob 5 rotates.

[0065] Reference Figure 2 In this embodiment, the potentiometer knob 5 may include three rotation areas, namely a first rotation area 51 , a second rotation area 52 and a third rotation area 53 .

[0066] When the potentiometer knob 5 rotates to the first rotation area 51, the variable temperature cooling temperature corresponding to the electrical signal of the potentiometer knob 5 is the refrigeration temperature. The refrigeration temperature is the temperature at which the variable temperature chamber 7 can be used to refrigerate fruits, vegetables and other items. For example, when the potentiometer knob 5 rotates to the first rotation area 51, the variable temperature cooling start temperature corresponding to the electrical signal of the potentiometer knob 5 is 6°C, and the variable temperature cooling stop temperature can be 4°C.

[0067] When the potentiometer knob 5 rotates to the second rotation area 52, the variable temperature cooling temperature corresponding to the electrical signal of the potentiometer knob 5 is the soft freezing temperature. The soft freezing temperature is the temperature at which the variable temperature chamber 7 can be used to soft-freeze items such as meat. For example, when the potentiometer knob 5 rotates to the second rotation area 52, the variable temperature cooling start temperature corresponding to the electrical signal of the potentiometer knob 5 is -2°C, and the variable temperature cooling stop temperature is -7°C.

[0068] When the potentiometer knob 5 is rotated to the third rotation area 53, the variable temperature cooling temperature corresponding to the electrical signal of the potentiometer knob 5 is the freezing temperature. The freezing temperature is a variable temperature that can be used to freeze items such as meat. For example, when the potentiometer knob 5 is rotated to the third rotation area 53, the variable temperature cooling start temperature corresponding to the electrical signal of the potentiometer knob 5 is -14°C, and the variable temperature cooling stop temperature is -18°C.

[0069] With such arrangement, the full temperature control of the variable temperature chamber 7 for refrigeration, soft freezing and freezing can be achieved by rotating a potentiometer knob 5 .

[0070] In this embodiment, each of the rotation areas may include at least three sub-rotation areas. The three sub-rotation areas may be a first sub-rotation area 501, a second sub-rotation area 502, and a third sub-rotation area 503. When the potentiometer knob 5 rotates to the first sub-rotation area 501, the electrical signal of the potentiometer knob 5 corresponds to the first refrigerated cooling temperature and the first variable temperature cooling temperature. When the potentiometer knob 5 rotates to the second sub-rotation area 502, the electrical signal of the potentiometer knob 5 corresponds to the second refrigerated cooling temperature and the second variable temperature cooling temperature. When the potentiometer knob 5 rotates to the third sub-rotation area 503, the electrical signal of the potentiometer knob 5 corresponds to the third refrigerated cooling temperature and the third variable temperature cooling temperature. The first refrigerated cooling temperature is higher than the second refrigerated cooling temperature. The second refrigerated cooling temperature is higher than the third refrigerated cooling temperature. The first variable temperature cooling temperature is higher than the second variable temperature cooling temperature. The second variable temperature cooling temperature is higher than the third variable temperature cooling temperature.

[0071] For example, when the potentiometer knob 5 is rotated to the first sub-rotation area 501 of the second rotation area 52, the electrical signal of the potentiometer knob 5 corresponds to the refrigeration start temperature of the first refrigeration temperature of 7°C, the refrigeration stop temperature of the first refrigeration temperature of 6°C, the variable temperature refrigeration start temperature of the first variable temperature refrigeration temperature of -2°C, and the variable temperature refrigeration stop temperature of the first variable temperature refrigeration temperature of -3°C; when the potentiometer knob 5 is rotated to the second sub-rotation area 502 of the second rotation area 52, the electrical signal of the potentiometer knob 5 corresponds to the refrigeration start temperature of the second refrigeration temperature of 5°C , the refrigeration stop temperature in the second refrigeration temperature is 4°C, the variable temperature refrigeration start temperature in the second variable temperature refrigeration temperature is -4°C, and the variable temperature refrigeration stop temperature in the second variable temperature refrigeration temperature is -5°C; when the potentiometer knob 5 is rotated to the second sub-rotation area 502 of the third rotation area 53, the refrigeration start temperature in the third refrigeration temperature corresponding to the electrical signal of the potentiometer knob 5 is 3°C, the refrigeration stop temperature in the third refrigeration temperature is 2°C, the variable temperature refrigeration start temperature in the third variable temperature refrigeration temperature is -6°C, and the variable temperature refrigeration stop temperature in the third variable temperature refrigeration temperature is -7°C.

[0072] With such an arrangement, when the temperature of the variable temperature chamber 7 corresponds to any one of the refrigeration temperature, soft freezing temperature and freezing temperature, the refrigeration cooling temperature of the refrigeration chamber 2 and the variable temperature cooling temperature of the variable temperature chamber 7 can be adjusted to at least three levels of weak, medium and strong, thereby ensuring full temperature control of the variable temperature chamber 7 and multi-level adjustment and precise control of the cooling temperature of the variable temperature chamber 7 and the cooling temperature of the refrigeration chamber 2 through a potentiometer knob 5.

[0073] Reference Figure 1Further, in this embodiment, “controlling the refrigeration system of the refrigerator 100 to supply cold to the cold storage room 2 according to the temperature of the cold storage room 2 and the cold storage and cooling temperature” specifically includes:

[0074] When it is detected that the temperature of the refrigerating chamber 2 reaches the refrigerating and cooling start temperature of the refrigerating and cooling temperature, the compressor of the refrigerating system is controlled to start, the evaporator of the refrigerating system is arranged in the evaporator chamber of the refrigerator 100, and a refrigerating air inlet duct 3 is arranged between the refrigerating chamber 2 and the evaporator chamber;

[0075] When it is detected that the temperature of the refrigerating chamber 2 reaches the refrigerating and cooling stop temperature room among the refrigerating and cooling temperatures, the compressor is controlled to stop.

[0076] The refrigerated air inlet duct 3 may be an air duct that directly passes through the evaporator chamber. No wind shielding structure such as a damper is provided in the refrigerated air inlet duct 3. When the compressor is started, the cold air in the evaporator chamber can naturally enter the refrigerated chamber 2 from the refrigerated air inlet duct 3 without additional control. A fan may be provided in the refrigerated air inlet duct 3. When the compressor is started, the fan in the refrigerated air inlet duct 3 may also be controlled to start, so that the cold air in the evaporator chamber can quickly flow to the refrigerated chamber 2.

[0077] With such an arrangement, the start and stop of the refrigeration system compressor can be controlled according to the refrigeration temperature, thereby controlling the cooling supply to the refrigeration chamber 2.

[0078] Reference Figure 1 Further, in this embodiment, “controlling the cooling of the refrigeration system to the variable temperature chamber 7 according to the temperature of the variable temperature chamber 7 and the variable temperature cooling temperature” specifically includes:

[0079] During the operation of the compressor, when it is detected that the temperature of the variable temperature chamber 7 reaches the variable temperature cooling start temperature in the variable temperature cooling temperature, the variable temperature damper 8 is controlled to open, and the variable temperature damper 8 is arranged in the variable temperature air inlet duct 9, and the variable temperature air inlet duct 9 is arranged between the variable temperature chamber 7 and the evaporator chamber;

[0080] When it is detected that the temperature of the variable temperature chamber 7 reaches the variable temperature cooling stop temperature chamber in the variable temperature cooling temperature, the variable temperature damper 8 is controlled to close.

[0081] With such an arrangement, it is possible to control the opening and closing of the variable temperature damper 8 according to the variable temperature cooling temperature during the operation of the compressor, thereby controlling the cooling supply to the variable temperature chamber 7.

[0082] Reference Figure 1 Furthermore, in this embodiment, the storage chamber includes a freezing chamber 12, and the freezing chamber 12 can be arranged below the variable temperature chamber 7. The control method of the refrigerator 100 also includes:

[0083] The freezing and refrigeration air volume ratio of the freezing air inlet duct 11 and the refrigeration air inlet duct 3 is controlled according to the electrical signal of the potentiometer knob 5, and the freezing air inlet duct 11 is arranged between the freezing chamber 12 and the evaporator chamber.

[0084] The refrigeration air inlet duct 11 may be an air duct that directly passes through the evaporator chamber. No wind shielding structure such as a damper is provided in the refrigeration air inlet duct 11. When the compressor is started, the cold air in the evaporator chamber can naturally enter the freezing chamber 12 from the refrigeration air inlet duct 11 without additional control. A fan may be provided in the refrigeration air inlet duct 11. When the compressor is started, the fan in the refrigeration air inlet duct 11 may be controlled to start, so that the cold air in the evaporator chamber can quickly flow to the freezing chamber 12.

[0085] The freezing and refrigeration air volume ratio is the ratio of the air volume of the freezing air inlet duct 11 to the air volume of the refrigeration air inlet duct 3 during the operation of the compressor.

[0086] When the potentiometer knob 5 is rotated to the first sub-rotation area 501, the freezing and refrigerating air volume ratio is controlled to be the first freezing and refrigerating air volume ratio. When the potentiometer knob 5 is rotated to the second sub-rotation area 502, the freezing and refrigerating air volume ratio is controlled to be the second freezing and refrigerating air volume ratio. When the potentiometer knob 5 is rotated to the third sub-rotation area 503, the freezing and refrigerating air volume ratio is controlled to be the third freezing and refrigerating air volume ratio. The first freezing and refrigerating air volume ratio is smaller than the second freezing and refrigerating air volume ratio, and the second freezing and refrigerating air volume ratio is smaller than the third freezing and refrigerating air volume ratio. For example, the first freezing and refrigerating air volume ratio is 7:3; the second freezing and refrigerating air volume ratio is 8:2; and the third freezing and refrigerating air volume ratio is 9:1.

[0087] Since the compressor is started and stopped according to the temperature of the refrigerating chamber 2, when the freezing and refrigerating air volume ratio is higher, the evaporator chamber supplies less cold air to the refrigerating chamber 2 per unit time, and the longer the compressor operation time required to reach the refrigerating and cooling stop temperature, the more cold air the evaporator chamber provides to the freezing chamber 12, so when the compressor stops running, the temperature of the freezing chamber 12 is lower. Therefore, in this arrangement, the cooling of the freezing chamber 12 is ensured by a potentiometer knob 5.

[0088] Reference Figure 1 Further, in this embodiment, “controlling the freezing and refrigeration air volume ratio of the freezing air inlet duct 11 and the refrigeration air inlet duct 3 according to the electrical signal of the potentiometer knob 5” specifically includes:

[0089] The fan speed is controlled according to the electrical signal of the potentiometer knob 5, and the fan is arranged in the refrigeration air inlet duct 3 or the freezing air inlet duct 11. By controlling the fan speed, the freezing and refrigeration air volume ratio can be accurately controlled, and the corresponding relationship between the freezing and refrigeration air volume ratio and the fan speed can be determined in advance by the research and development personnel through experiments and other methods.

[0090] In this embodiment, the size relationship between the refrigerated air inlet duct 3, the variable temperature air inlet duct 9, the frozen air inlet duct 11, and the variable temperature damper 8 can be determined in advance by the R&D personnel through experiments or the like, so that in a refrigeration cycle of the refrigerated chamber 2, when the variable temperature damper 8 is fully open, when the compressor stops, the temperature of the variable temperature chamber 7 and the freezing chamber 12 can reach the lowest temperature among the preset freezing temperatures.

[0091] Reference Figure 1 Furthermore, in this embodiment, the control method of the refrigerator 100 further includes:

[0092] When the compressor stops running, detecting the external environment temperature of the refrigerator 100;

[0093] When the external environment temperature is lower than the set temperature, the heating element 4 in the refrigerating chamber 2 is controlled to start;

[0094] When the compressor is running, the heating element 4 is controlled to stop.

[0095] The set temperature may be 13° C. The heating element 4 is a heating wire. With such a configuration, when the external environment temperature is low, during the period when the compressor is stopped, the temperature of the refrigerating chamber 2 can be compensated by the heating element 4 to increase the temperature of the refrigerating chamber 2 .

[0096] The second embodiment of the present invention is as follows:

[0097] Reference Figures 1 to 3 The structure and control method of the refrigerator 100 in this embodiment are the same as those in the first embodiment except for the differences described below.

[0098] One of the differences between this embodiment and the first embodiment is that the refrigeration air inlet duct 3 is provided with a refrigeration damper, and the opening and closing of the refrigeration damper and the start and stop of the compressor are controlled according to the refrigeration temperature, thereby realizing the refrigeration of the refrigeration room 2.

[0099] Reference Figure 1 In this embodiment, “controlling the refrigeration system of the refrigerator 100 to supply cold to the refrigerating chamber 2 according to the temperature of the refrigerating chamber 2 and the refrigerating supply temperature” specifically includes:

[0100] When it is detected that the temperature of the refrigerating chamber 2 reaches the refrigerating supply start temperature in the refrigerating supply temperature, the refrigerating air door is controlled to open, and the compressor of the refrigerating system is controlled to operate, the evaporator of the refrigerating system is arranged in the evaporator chamber of the refrigerator 100, a refrigerating air inlet duct 3 is arranged between the refrigerating chamber 2 and the evaporator chamber, and the refrigerating air door is arranged in the refrigerating air inlet duct 3;

[0101] When it is detected that the temperature of the refrigerating chamber 2 reaches the refrigerating and cooling stop temperature room among the refrigerating and cooling temperatures, the refrigerating damper is controlled to be closed.

[0102] Reference Figure 1 The second difference between this embodiment and the first embodiment is that the opening and closing of the variable temperature damper 8 and the start and stop of the compressor are controlled according to the variable temperature cooling temperature, so as to realize cooling to the variable temperature room 7.

[0103] In this embodiment, “controlling the cooling of the refrigeration system to the variable temperature chamber 7 according to the temperature of the variable temperature chamber 7 and the variable temperature cooling temperature” specifically includes:

[0104] When it is detected that the temperature of the variable temperature chamber 7 reaches the variable temperature cooling start temperature in the variable temperature cooling temperature, the variable temperature damper 8 is controlled to open, and the compressor of the refrigeration system is controlled to operate, a variable temperature air inlet duct 9 is provided between the variable temperature chamber 7 and the evaporator chamber, and the variable temperature damper 8 is provided in the variable temperature air inlet duct 9;

[0105] When it is detected that the temperature of the variable temperature chamber 7 reaches the variable temperature cooling stop temperature chamber in the variable temperature cooling temperature, the variable temperature damper 8 is controlled to close.

[0106] With such an arrangement, the compressor start and stop can be controlled respectively by the temperature of the cold storage room 2 and the temperature of the variable temperature room 7, which can better ensure the cooling of the cold storage room 2 and the variable temperature room 7 by the refrigeration system and avoid mutual influence between the two.

[0107] Reference Figure 1 The third difference between this embodiment and the first embodiment is that the cooling system can supply cooling to the freezing chamber 12 by extending the operation time of the compressor.

[0108] In this embodiment, the control method of the refrigerator 100 further includes:

[0109] When the refrigeration damper and the temperature-variable damper 8 are both closed, the compressor is controlled to run for a preset time, and the fan of the freezing air inlet duct 11 is controlled to run. The freezing air inlet duct 11 is arranged between the freezer chamber 12 of the refrigerator 100 and the evaporator chamber.

[0110] Furthermore, in this embodiment, the control method of the refrigerator 100 further includes:

[0111] Detecting the external ambient temperature of the refrigerator 100;

[0112] The preset time duration is obtained according to the external environment temperature.

[0113] When the external environment temperature is lower, when the refrigeration damper and the temperature-variable damper 8 are both closed, the fan operation time of the compressor and the freezing air inlet duct 11 is shorter.

[0114] Determining the extended operation time of the compressor according to the external ambient temperature can achieve more accurate cooling for the freezer compartment 12. For example, when the external ambient temperature is less than 13°C, when the refrigeration damper and the variable temperature damper 8 are both closed, the compressor is controlled to continue to operate for 13 minutes; when the external ambient temperature is between 13°C and 35°C, when the refrigeration damper and the freezing damper are both closed, the compressor is controlled to continue to operate for 15 minutes; when the external ambient temperature is greater than 35°C, when the refrigeration damper and the freezing damper are both closed, the compressor is controlled to continue to operate for 20 minutes.

[0115] The present invention also includes a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the steps in the control method of the refrigerator 100 described in any one of the above-mentioned embodiments.

[0116] In summary, the control method, storage medium, and refrigeration device of the refrigeration equipment of the present invention can solve the problem of high cost of the electronic refrigerator 100 or the computer refrigerator 100. By adopting the technical solution of the present application, a potentiometer knob 5 can realize full temperature control of refrigeration, soft freezing, and freezing of the variable temperature chamber 7, and a potentiometer knob 5 can realize multi-level adjustment and precise control of the temperature of the refrigeration chamber 2, the variable temperature chamber 7, and the freezing chamber 12, thereby reducing the cost of the refrigeration equipment.
