Description

Technical Field

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

[0002] Currently, the start and stop of a refrigerator's refrigeration system is generally controlled based on the internal temperature of the refrigeration compartment. In existing refrigerators, the internal temperature of the refrigeration compartment is generally measured by a compartment temperature sensor installed on the side wall of the refrigeration compartment. However, if a user piles a large amount of food near the compartment temperature sensor, the compartment temperature sensor's sensitivity decreases, making it unable to accurately measure the internal temperature of the refrigeration compartment, thus affecting the start and stop control of the refrigeration system. In this case, the refrigerator is prone to long-term shutdown, which greatly affects the cooling effect. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0051] See also Figure 1 , is a flowchart of a controller in a refrigerator provided by one embodiment of the present invention.

[0052] This embodiment provides a refrigerator, comprising:

[0053] The box body has a refrigeration compartment inside; the refrigeration compartment has a door at its opening;

[0054] A refrigeration system for refrigerating the refrigeration compartment;

[0055] A door switch detection device, used to detect the switch status of the box door and send it to the controller;

[0056] The controller is configured to:

[0057] S11. When the refrigerator is operating in a cooling mode, obtaining a condition judgment parameter; wherein the condition judgment parameter includes a continuous closing time of the door;

[0058] S12. Determine whether a forced start control condition is met based on the condition judgment parameter; wherein the forced start control condition includes that the continuous shutdown time reaches a preset time;

[0059] S13. If it is determined that the forced startup control condition is met, then when the refrigeration system is in a shutdown state, the current allowed shutdown time and the continuous shutdown time of the refrigeration system are obtained, and when it is detected that the continuous shutdown time reaches the current allowed shutdown time, the refrigeration system is controlled to switch to the running state.

[0060] It should be noted that the refrigerator can be an air-cooled refrigerator, and is not limited to the door type and refrigeration system (single system, double system, triple system, etc.).

[0061] In this embodiment, see Figure 2 The refrigeration system includes the following components: evaporator 1, condenser ( Figure 2 Not shown), compressor 2, capillary tube ( Figure 2 The evaporator 1 is the refrigeration unit, specifically including the evaporator body, which provides cooling for the refrigerator. The compressor 2 is the power source of the refrigeration system, driving the refrigerant in the system for transfer and heat exchange. The fan 3 is the power source of the air supply system, transferring the cooling energy from the evaporator surface to the refrigerated room through the air duct 4. It will be understood that the controller switches the refrigeration system into operation by controlling the activation of the compressor 2 and fan 3.

[0062] It should be noted that the continuous downtime of the refrigeration system refers to the duration of the current downtime of the refrigeration system.

[0063] In a specific embodiment, see Figure 2 The refrigerator provided in this embodiment also includes a compartment temperature sensor 5 and an ambient temperature sensor 6. The compartment temperature sensor 5 is placed on the side wall of the refrigeration compartment. The refrigerator controls the start and stop of the compressor and fan by sensing the temperature of the sensor 5. The ambient temperature sensor 6 is a device that senses the current ambient temperature and can control the compressor and fan according to different ambient temperatures.

[0064] It can be understood that if the forced start control conditions are met, it means that the user has not used the refrigerator for some time, that is, the refrigerator is in a relatively stable state. If the continuous downtime of the refrigeration system exceeds the currently allowed downtime, it means that the downtime of the refrigerator is too long. At this time, the refrigeration system is controlled to switch to the running state, thereby preventing the refrigerator from being shut down for a long time and achieving the purpose of maintaining the refrigeration effect of the refrigerator.

[0065] In a specific embodiment, the preset time is 6 hours.

[0066] The refrigerator provided in this embodiment, when the refrigerator is operating in the refrigeration mode, if it is determined based on the acquired condition judgment parameters that the forced start control condition is satisfied, then when the refrigeration system of the refrigerator is in the shutdown state, the current allowed shutdown time and the continuous shutdown time of the refrigeration system are obtained, and when it is detected that the continuous shutdown time reaches the current allowed shutdown time, the refrigeration system is controlled to switch to the running state, thereby effectively preventing the refrigeration system of the refrigerator from being shut down for a long time, thereby achieving the purpose of maintaining the refrigeration effect of the refrigerator.

[0067] In an optional embodiment, the current allowed downtime may be pre-stored in the controller.

[0068] In another optional embodiment, the refrigerator further includes an ambient temperature sensor 6 for detecting the ambient temperature and sending it to the controller; the controller may obtain the current ambient temperature; and determine the current allowed downtime corresponding to the current ambient temperature based on a preset correspondence between the ambient temperature and the allowed downtime.

[0069] Through this embodiment, the current allowed downtime is adjusted according to the current ambient temperature, so that the refrigeration system can be controlled to perform refrigeration according to different ambient temperatures, which can effectively reduce the cost and operating energy consumption of the refrigerator and is conducive to the stability of refrigerator refrigeration.

[0070] As one of the optional implementations, the preset corresponding relationship is shown in Table 1.

[0071] Table 1

[0072]

[0073] As another optional implementation, for more precise control, the preset correspondence is specifically:

[0074] t=a-Te

[0075] Where, t is the allowable downtime, a is equal to 70, and Te is the ambient temperature.

[0076] As one of the optional embodiments, the refrigerator further includes a gear adjustment device, configured to generate and send a gear adjustment signal to the controller; wherein the gear adjustment signal includes a target gear;

[0077] The controller is further configured to:

[0078] In response to receiving the gear adjustment signal, adjusting the operating parameters of the refrigeration system according to the target gear, so that the refrigerator is adjusted to the target gear;

[0079] The condition judgment parameter also includes the gear holding time of the refrigerator being maintained at the current gear;

[0080] The forced start control condition also includes that the gear holding time reaches the preset time.

[0081] In this embodiment, the refrigerator also includes a gear adjustment device, the condition judgment parameter also includes the gear holding time for the refrigerator to maintain the current gear, and the forced start control condition also includes the gear holding time reaching the preset time. If the continuous shutdown time reaches the preset time and the gear holding time reaches the preset time, it is determined that the forced start control condition is met, which can improve the accuracy of the refrigerator stability judgment, thereby accurately controlling the forced start of the refrigeration system to prevent the indoor temperature of the refrigeration room from being too low.

[0082] As one of the optional embodiments, the refrigerator further includes a compartment temperature sensor 5 for detecting the internal temperature of the refrigeration compartment and sending the temperature to the controller;

[0083] The controller is further configured to:

[0084] If it is determined that the forced start control condition is met, then when the refrigeration system is in the running state, obtaining the current internal temperature and the set shutdown temperature of the refrigeration compartment, and controlling the refrigeration system to switch to the shutdown state when it is detected that the current internal temperature reaches the set shutdown temperature;

[0085] If it is determined that the forced startup control condition is not met, the current internal temperature, the set startup temperature and the set shutdown temperature of the refrigeration compartment are obtained, and the refrigeration system is controlled to switch to the running state or the shutdown state according to the current internal temperature, the set startup temperature and the set shutdown temperature.

[0086] It can be understood that the controller switches the refrigeration system to an operating state or a shutdown state by controlling the compressor 2 and the fan 3 to start or stop.

[0087] It should be noted that when the refrigerator includes a gear adjustment device, the controller pre-sets the correspondence between each gear and the set shutdown temperature and the set startup temperature. The controller can obtain the set startup temperature and the set shutdown temperature based on the current gear of the refrigerator and the correspondence; when the refrigerator does not include a gear adjustment device, the controller pre-sets the set shutdown temperature and the set startup temperature.

[0088] In this embodiment, if it is determined that the forced start-up control condition is not met, the refrigerator controls the start and stop of the refrigeration system according to the current internal temperature, the set start-up temperature and the set shutdown temperature. If the forced start-up control condition is met and the shutdown time is too long, the refrigeration system is controlled to switch to the running state, thereby preventing the refrigerator from being shut down for a long time and achieving the purpose of maintaining the refrigeration effect of the refrigerator.

[0089] In a specific embodiment, the workflow of the controller is as follows:

[0090] Step 1: When the refrigerator is in cooling mode, determine whether the door's continuous closing time and the gear holding time are greater than a preset time. If so, proceed to step 2.

[0091] Step 2: When the current internal temperature of the refrigeration compartment reaches the preset shutdown temperature, the compressor and the fan are controlled to shut down normally, and the process proceeds to step 3;

[0092] Step 3: determining the current allowable downtime corresponding to the current ambient temperature according to a preset correspondence between the ambient temperature and the allowable downtime, and proceeding to step 4 when it is detected that the continuous downtime of the refrigeration system reaches the current allowable downtime;

[0093] Step 4: Control the compressor and fan to switch to the running state and proceed to step 5;

[0094] Step 5: When the current internal temperature of the refrigeration compartment reaches the preset shutdown temperature, the compressor and the fan are controlled to shut down normally, and the process proceeds to step 6;

[0095] Step 6, determine whether the gear is adjusted or the door is opened, if so, go to step 7, if not, return to step 3;

[0096] Step 7: Control the start and stop of the compressor and the fan according to the current internal temperature of the refrigeration compartment, the preset start temperature, and the preset stop temperature, and return to step 1.
