[0031] Figure 1 It is a flow chart of the refrigeration control method of the refrigerator of the present invention when it is in the strong gear;
[0032] Figure 2 The present invention is a flow chart of the refrigerator refrigeration control method when it is in the middle and low gear. DETAILED DESCRIPTION
[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.
[0034] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0035] Combination Figure 1 and Figure 2 As shown, the present invention mainly relates to a refrigeration control method for a refrigerator, comprising:
[0036] Obtaining the setting level T of the temperature of the refrigerator compartment;
[0037] When the setting gear T is in the strong gear, the start-up temperature threshold and the shutdown temperature threshold of the refrigerated compartment are set to t on 1 ,t off1 ;
[0038] When the setting gear T is at a medium or low gear, it is determined whether vegetables are stored in the refrigerator;
[0039] When it is found that there are vegetables in the refrigerator, the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on2 ,t off2 , where t on2 -t off2 ≥t on 1 -t off1 ;
[0040] When it is found that there are no vegetables in the refrigerator, the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on3 ,t off3 , where t on3 -t off3 >t on2 -t off2 .
[0041] Specifically, the set temperature corresponding to the medium and low gear is greater than the set temperature corresponding to the strong gear. For example, the set temperature of the medium and low gear is 5°C, and the set temperature of the strong gear is 1°C.
[0042] When the actual temperature in the refrigerator compartment is greater than or equal to the startup temperature threshold of the refrigerator compartment, the compressor is started to cool the refrigerator compartment. When the actual temperature in the refrigerator compartment is less than or equal to the shutdown temperature threshold of the refrigerator compartment, the compressor is turned off. The set temperature of the refrigerator compartment is between the shutdown temperature threshold and the startup temperature threshold. The startup temperature threshold is the preset temperature value added to the set temperature of the refrigerator compartment. The shutdown temperature threshold is the preset temperature value subtracted from the set temperature of the refrigerator compartment. The preset temperature value can be 0 or other values.
[0043] Reference Figure 1 As shown, when the setting gear T is in the strong gear, the setting temperature of the refrigerator compartment is low, and the on / off temperature of the refrigerator compartment is turned on and off alternately to ensure freshness and non-frozen vegetables. The on / off alternately means that the difference between the on-temperature threshold and the off-temperature threshold of the refrigerator compartment is small.
[0044] Reference Figure 2 As shown, when the setting gear T is at a medium or low gear, the setting temperature of the refrigerator compartment is moderate or high, and the on / off temperature of the refrigerator compartment is determined according to whether vegetables are stored in the refrigerator compartment.
[0045] When there are no vegetables in the cold storage room, there will be no problem of frozen vegetables. The on / off temperature of the cold storage room is high on / off, which reduces the frequency of starting and stopping the compressor and achieves the purpose of energy saving. High on / off means that the difference between the on-temperature threshold and the off-temperature threshold of the cold storage room is large.
[0046] When there are vegetables in the cold storage room, the setting temperature of the cold storage room is moderate or high and energy saving is taken into consideration. At this time, the switch temperature of the cold storage room is a temperature between low opening and low stopping or high opening and low stopping.
[0047] t on3 -t off3 >t on2 -t off2 ≥t on 1 -t off1 .
[0048] When the gear T is set to the strong gear, the start-up temperature threshold and the shutdown temperature threshold of the refrigerated compartment are t on 1 ,t off1 ; For example, the set temperature of the cold storage room is 1℃, t on 1 1.5℃, t off1 1℃, t on 1 -t off =0.5℃.
[0049] When the gear position T is set to medium or low and there are vegetables in the refrigerator, the startup temperature threshold and shutdown temperature threshold of the refrigerator are t on 2 ,t off2 .
[0050] When the gear position T is set to medium or low and there is no vegetable in the refrigerator, the startup temperature threshold and shutdown temperature threshold of the refrigerator are t on 3 ,t off3 For example, the set temperature of the cold storage room is 4℃, t on 3 6.5℃, t off3 2.5℃, t on3 -t off3 =4℃.
[0051] Thus 0.5℃≤t on 2 -t off2 <4℃.
[0052] By adaptively and finely setting the on / off temperature of the refrigerating compartment according to the different setting gears T of the refrigerating compartment and the storage conditions of the vegetables, the effect of energy saving and preventing the vegetables from freezing can be achieved. It has the advantages of high energy saving, good refrigeration effect and good preservation effect.
[0053] Further, when it is obtained that there are vegetables in the cold storage room, the location of the vegetables is obtained;
[0054] When the position of the vegetables relative to the air outlet of the refrigerated compartment is within the preset range, set t on2 -t off2 =t on 1 -t off1 ;
[0055] When it is found that the position of the vegetable relative to the air outlet of the refrigerated compartment is not within the preset range, t is set according to the type of vegetable. on2 With toff2 The numerical value of .
[0056] Specifically, when the position of the vegetables relative to the air outlet of the refrigerating compartment is within the preset range, it means that the vegetables are arranged at or near the air outlet of the refrigerating compartment. At this time, the problem of frozen vegetables is very likely to occur. In order to avoid the problem of frozen vegetables, t is set. on2 -t off2 =t on 1 -t off1 The temperature of the refrigerator compartment is switched on and off at low speeds to ensure the freshness of the vegetables and prevent them from freezing.
[0057] When vegetables are far away from the air outlet of the cold storage room, the probability of freezing is reduced. The on / off temperature of the cold storage room should be determined according to the type of vegetables. Some vegetables, such as leafy vegetables, are prone to freezing, while some vegetables, such as tomatoes, are not. Fine control takes into account the effects of refrigeration, freshness preservation and energy saving.
[0058] Further, when it is obtained that the position of the vegetables relative to the air outlet of the refrigerating chamber is not within a preset range, whether the vegetables include leafy vegetables is obtained;
[0059] When vegetables include leafy vegetables, set t on2 -t off2 =t on 1 -t off1 ;
[0060] When vegetables do not include leafy vegetables, set t on2 -t off2 >t on 1 -t off1 .
[0061] Specifically, leafy vegetables are leafy vegetables. Leafy vegetables are vegetables with leaves or leaf stems as edible parts. Whether the leafy vegetables are fresh or not will greatly affect their taste and nutritional value. Therefore, leafy vegetables are prone to freezing, and the refrigeration and preservation effect of leafy vegetables is extremely important. Leafy vegetables include Chinese cabbage, Chinese cabbage, greens, cabbage, lettuce, leek, leek, celery, spinach, asparagus, lettuce, water spinach, chrysanthemum, amaranth, Chongcai, Gongcai, kale, mustard greens, baby cabbage, and fennel.
[0062] When the vegetables are far away from the air outlet of the refrigerated compartment and the vegetables include leafy vegetables, in order to avoid the problem of frozen vegetables, set t on2 -t off2 =t on 1 -t off1 The temperature of the refrigerator compartment is switched on and off at low speeds to ensure the refrigeration and freshness of the vegetables.
[0063] When the vegetables are far away from the air outlet of the cold storage room and the vegetables do not include leafy vegetables, the probability of freezing of vegetables is reduced. The on / off temperature of the cold storage room is a temperature between low on and low off or high on and high off, taking into account both energy saving and the effect of refrigeration and preservation of non-leafy vegetables.
[0064] Furthermore, when the setting gear T is at a medium or low gear, a refrigerator door opening signal is obtained, and the storage status of vegetables in the refrigerator compartment is obtained;
[0065] After receiving the door closing signal, check whether the storage conditions of vegetables in the cold storage room have changed;
[0066] When the storage conditions of vegetables in the refrigerator room remain unchanged after the door is closed, the startup temperature threshold and shutdown temperature threshold of the refrigerator room remain unchanged;
[0067] When the user has taken out all the vegetables in the refrigerator after closing the door, the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on3 ,t off3 ;
[0068] When the door is closed, it is found that vegetables are added to the refrigerator, and the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on2 ,t off2 .
[0069] Specifically, because when the setting gear T is at a medium or low gear, it is necessary to finely control the on / off temperature of the refrigeration compartment according to the storage conditions of vegetables in the refrigeration compartment.
[0070] If the storage situation of vegetables changes, such as adding or removing, the door needs to be opened and closed to operate.
[0071] Therefore, when there is a signal to open or close the door, it is more reasonable to obtain the storage status of vegetables in the cold storage room. There is no need to continuously monitor the storage status of vegetables. The control method is simpler and more reasonable.
[0072] When a door opening signal is obtained, the storage status of the vegetables in the cold storage room is immediately obtained, thereby obtaining the original storage status of the vegetables in the cold storage room of the refrigerator.
[0073] When the door is closed, the storage situation of vegetables in the cold storage room does not change, which means that the user did not store or take out vegetables this time.
[0074] When the user has taken out all the vegetables in the refrigerator after closing the door, the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on3 ,t off3When there are no vegetables in the cold storage room, there will be no problem of frozen vegetables. The on / off temperature of the cold storage room is high on / off, which reduces the frequency of starting and stopping the compressor and achieves the purpose of energy saving.
[0075] When the door is closed, it is found that vegetables are added to the refrigerator, and the startup temperature threshold and shutdown temperature threshold of the refrigerator are set to t on2 ,t off2 Taking into account the dual factors of moderate or high setting temperature of the refrigerated room and energy saving, at this time, the on / off temperature of the refrigerated room is a temperature between small opening and small stopping or small opening and small stopping and large opening and large stopping. on3 -t off3 >t on2 -t off2 ≥t on 1 -t off1 .
[0076] Furthermore, the storage conditions of vegetables in the cold storage room are obtained through a camera inside the cold storage room.
[0077] Specifically, the camera can be set on the vertical beam of the refrigerator. When the door is opened or closed, the camera is controlled to obtain the storage conditions of vegetables in the cold storage room. The structure is simple and easy to achieve.
[0078] Furthermore, the storage status of vegetables in the cold storage room is obtained through a mobile communication device loaded with APP software that communicates with the refrigerator;
[0079] The APP software of the mobile communication device is used to record the storage conditions of vegetables in the cold storage room.
[0080] Specifically, the APP software of the mobile communication device can manually add vegetables stored in the refrigerator or automatically add vegetables stored in the refrigerator by other means. The APP software of the mobile communication device can communicate with the control unit of the refrigerator.
[0081] Furthermore, the aforementioned startup temperature threshold is negatively correlated with the value of the ambient temperature;
[0082] The aforementioned shutdown temperature threshold is negatively correlated with the value of the ambient temperature.
[0083] Specifically, take the setting temperature as 1°C and high gear as an example:
[0084] When the ambient temperature ranges from 0 to 20°C, t on 1 2℃, t off1 is 1.5℃.
[0085] When the ambient temperature ranges from 20℃ to 30℃, t on 11.5℃, t off1 is 1℃.
[0086] When the ambient temperature is above 30℃, t on 1 1℃, t off1 is 0.5℃.
[0087] When the ambient temperature is higher, the refrigeration demand of the refrigerated compartment is greater, and the aforementioned startup temperature threshold and the aforementioned shutdown temperature threshold are smaller, so as to meet the refrigeration demand of the refrigerated compartment as quickly as possible and increase the start and stop frequency of the compressor.
[0088] Furthermore, when the ambient temperature ranges from 20°C to 30°C, t on 1 -t off1 =0.5℃; t on3 -t off3 =4℃.
[0089] Furthermore, the set temperature corresponding to the aforementioned strong gear ranges from 1 to 3°C.
[0090] The set temperature range corresponding to the above-mentioned medium and low gears is 4 to 10°C.
[0091] A refrigerator comprises a control unit, the control unit comprises a memory and a processor, the memory stores a computer program that can be run on the processor, and the processor implements the refrigerator refrigeration control method as described above when executing the computer program.
[0092] The refrigerator includes a box body. The box body defines a refrigerating compartment. A refrigerating system for supplying cold to the refrigerating compartment is arranged in the box body. The refrigerating system includes a compressor.
[0093] Furthermore, the refrigerator also includes a camera arranged in the cold storage room. The camera can be arranged on the vertical beam of the refrigerator. When the door is opened or closed, the camera is controlled to obtain the storage status of vegetables in the cold storage room. The refrigerator has a simple structure and is easy to achieve.
[0094] Compared with the prior art, the refrigerator refrigeration control method provided by the present invention can adaptively perform multiple fine settings on and off temperatures of the refrigeration compartment according to different setting gears T of the refrigeration compartment and the storage conditions of vegetables. on 1 -t off1 When the temperature is less than or equal to medium-low level and there are vegetables in the cold storage room, t on 2 -t off2 ; Medium and low-grade, and when there are vegetables in the refrigerator on 2 -t off2Less than the medium and low grade, and when there are no vegetables in the cold storage room on 3 -t off3 ; Take into account the setting gear T and the storage conditions of vegetables to achieve the effect of energy saving and non-freezing vegetables. It has the advantages of energy saving and high efficiency, good refrigeration effect, good preservation effect and fine control.
[0095] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
