Description

Technical Field

[0001] The invention belongs to the technical field of food preservation equipment, and specifically provides a preservation equipment and a control method thereof. Background Art

[0002] The current fresh-keeping equipment mainly includes refrigerators, freezers, and freezers, which mainly preserve the food inside by lowering the temperature of the internal fresh-keeping compartment.

[0003] However, the nature of oxygen in the air is very active and can still cause a variety of deterioration reactions and corruption in food. Oxygen destroys nutrients, pigments, flavor substances and other components of food by participating in oxidation reactions. At the same time, oxygen is also a necessary condition for the growth of aerobic microorganisms. Under aerobic conditions, the deterioration reaction caused by the reproduction of microorganisms is accelerated, resulting in a shortened storage period of food.

[0004] In order to overcome the above problems, some fresh-keeping equipment is also equipped with an air conditioning device to consume the oxygen in the fresh-keeping room through the air conditioning device, thereby reducing the oxygen content in the fresh-keeping room. Specifically, the air conditioning device includes a cathode, an anode, and an electrolyte filled between the cathode and the anode. The air conditioning device contacts the air in the fresh-keeping room through the cathode, so that the oxygen undergoes a reduction reaction at the cathode, namely: O2+2H2O+4e - →4OH - . An oxidation reaction occurs at the anode, and oxygen is generated, namely: 4OH - →O2+2H2O+4e - . Thus, the atmosphere conditioning device can adjust the oxygen concentration in the fresh-keeping room.

[0005] However, the atmosphere control device in the existing fresh-keeping equipment can only adjust the oxygen concentration in one fresh-keeping room. If the oxygen concentration of multiple fresh-keeping rooms needs to be adjusted, an atmosphere control device needs to be configured for each fresh-keeping room. This not only increases the cost of the fresh-keeping equipment, but also occupies more space in the fresh-keeping equipment, resulting in a low volume ratio of the fresh-keeping equipment. Summary of the invention

[0006] One object of the present invention is to solve the problem that the atmosphere control device in the existing fresh-keeping equipment cannot perform atmosphere control for multiple fresh-keeping compartments.

[0007] One object of the present invention is to enable each fresh-keeping compartment of a fresh-keeping device to maintain an adjusted oxygen concentration.

[0008] To achieve the above-mentioned object, the present invention provides a control method for a fresh-keeping device in a first aspect, wherein the fresh-keeping device comprises a box body defining at least two fresh-keeping compartments, an air conditioning device, a fan, at least two dampers and at least two door bodies, wherein the fan is used to drive air to flow between the fresh-keeping compartment and the air conditioning device, so that the air conditioning device adjusts the oxygen concentration in the fresh-keeping compartment through an electrochemical reaction; the fresh-keeping compartment, the damper and the door body correspond to each other one by one, and the damper is used to control whether the air in the corresponding fresh-keeping compartment flows to the air conditioning device; the control method comprises:

[0009] In response to at least one of the door bodies changing from an open state to a closed state, the door body is recorded as a first target door body, and the air conditioning device is controlled to operate;

[0010] In response to the air conditioning device running for a first preset time, controlling the damper corresponding to the first target door body to open, and controlling the fan to run;

[0011] In response to reaching a preset condition, the air conditioning device and the fan are controlled to stop running.

[0012] Optionally, after the step of controlling the air conditioning device and the fan to stop running, the control method further includes:

[0013] In response to the continuous failure to detect a change in the state of any of the door bodies, the air conditioning device is controlled to operate for a third preset time period every second preset time period, and the fan is controlled to operate for a fourth preset time period.

[0014] Optionally, the step of controlling the fan to run for a fourth preset time period includes:

[0015] The fan is controlled to run at f% of the rated speed for the fourth preset time period, where f is a positive number less than 100.

[0016] Optionally, the fourth preset time length is equal to the third preset time length, and the fan and the air conditioning device operate simultaneously; and / or,

[0017] f=50.

[0018] Optionally, in response to reaching a preset condition, the step of controlling the air conditioning device and the fan to stop running includes:

[0019] In response to the preset condition being reached, the fan is controlled to stop running, and the air conditioning device is controlled to run for a fifth preset time before stopping.

[0020] Optionally, the preset condition is that the oxygen concentration in all the fresh-keeping rooms with the dampers in the open state has reached a preset threshold.

[0021] Optionally, the control method further includes:

[0022] In response to at least one of the door bodies changing from a closed state to an open state, it is recorded as a second target door body, and the corresponding damper is controlled to close.

[0023] Optionally, the fresh-keeping device is a refrigerator.

[0024] In a second aspect, the present invention provides a fresh-keeping device, comprising:

[0025] The box body is defined with at least two fresh-keeping compartments;

[0026] At least two door bodies, each of which corresponds to one of the fresh-keeping compartments;

[0027] Gas conditioning device;

[0028] A fan, used for driving air to flow between the fresh-keeping compartment and the air conditioning device, so that the air conditioning device adjusts the oxygen concentration in the fresh-keeping compartment through an electrochemical reaction;

[0029] At least two dampers, each damper corresponds to one of the fresh-keeping compartments, and the damper is used to control whether the air in the corresponding fresh-keeping compartment flows to the air conditioning device;

[0030] The controller comprises a memory and a processor, wherein a machine executable program is stored in the memory, and when the processor executes the machine executable program, the control method described in any one of the first aspects can be implemented.

[0031] Optionally, the box body is further defined with a circulating air duct, and each of the fresh-keeping compartments is respectively connected to the circulating air duct fluid; the atmosphere control device is configured to transfer oxygen from the inside to the outside of the circulating air duct, or to transfer oxygen from the outside to the inside of the circulating air duct through an electrochemical reaction.

[0032] Based on the foregoing description, it can be understood by those skilled in the art that, in the aforementioned technical solution of the present invention, by making the fan drive the air to flow between the fresh-keeping compartment and at least two air conditioning devices, the air conditioning device can adjust the oxygen concentration in the at least two fresh-keeping compartments through an electrochemical reaction. By making the fresh-keeping compartment, the damper and the door body correspond one to one, and controlling whether the air in the corresponding fresh-keeping compartment flows to the air conditioning device through the damper, the fresh-keeping device can control which fresh-keeping compartment the air conditioning device regulates oxygen through the damper. Therefore, the fresh-keeping device in the present invention can regulate the air of multiple fresh-keeping compartments through the same air conditioning device. Furthermore, when at least one door body changes from an open state to a closed state, the air conditioning device is controlled to operate; when the air conditioning device operates for a first preset time, the damper corresponding to the first target door body is controlled to open, and the fan is controlled to operate; in response to reaching a preset condition, the air conditioning device and the fan are controlled to stop operating; while realizing automatic oxygen concentration adjustment of the fresh-keeping compartment, the air conditioning device is operated in advance for a first preset time, thereby improving the efficiency of the air conditioning device in regulating the oxygen concentration in the corresponding fresh-keeping compartment.

[0033] Furthermore, after the air conditioning device and the fan are controlled to stop running, if no change in the state of any door body is detected, the air conditioning device is controlled to work for a third preset time period every second preset time period, and the fan is controlled to work for a fourth preset time period, thereby preventing the fresh-keeping compartment from being infiltrated by outside air due to a loose seal, causing the oxygen concentration therein to change. Therefore, the present invention also achieves the maintenance of the oxygen concentration in each fresh-keeping compartment by the fresh-keeping device.

[0034] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0043] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

Those skilled in the art should understand that, under the premise of being able to implement the technical solution described in the present invention, no matter how the composition, implementation and positional relationship of each functional module change, they will not deviate from the technical principle of the present invention, and therefore should fall within the protection scope of the present invention.

[0048] In the present invention, the fresh-keeping device can be a refrigerator. The refrigerator is a refrigerator in a broad sense, which not only includes the commonly known refrigerator in a narrow sense, but also includes fresh-keeping devices with refrigeration and / or freezing functions, such as refrigerators, freezers, etc.

[0049] like Figure 1 As shown, in the present invention, the fresh-keeping device 100 includes a box body 110 defining at least two fresh-keeping compartments 111 , at least two door bodies 120 , an air conditioning device 130 , a fan 140 and at least two dampers 150 .

[0050] The fresh-keeping chamber 111 is used to store food so that the fresh-keeping device 100 can keep the food fresh.

[0051] The door body 120 is used to shield the fresh-keeping compartment 111, thereby isolating the fresh-keeping compartment 111 from the external environment.

[0052] The fan 140 is used to drive air to flow between the fresh-keeping compartment 111 and the air conditioning device 130, so that the air conditioning device 130 adjusts the oxygen concentration in the fresh-keeping compartment 111 through an electrochemical reaction (as described in the background art).

[0053] The fresh-keeping compartment 111 , the damper 150 and the door body 120 correspond to each other one by one, and the damper 150 is used to control whether the air in the corresponding fresh-keeping compartment 111 flows to the air conditioning device 130 .

[0054] Furthermore, in the present invention, the number of the fresh-keeping compartments 111 can be Figures 1 to 3 In addition to the two shown in , it can also be any other feasible number, such as three, four, five, eight, etc.

[0055] The fresh-keeping device 100 of the present invention having the above structure can perform air conditioning on a plurality of fresh-keeping compartments 111 through the same air conditioning device 130 .

[0056] like Figures 1 to 3 As shown, in the present invention, the box body 110 may further define a circulation air duct 112, and each fresh-keeping compartment 111 is respectively in fluid communication with the circulation air duct 112. Specifically, an air inlet 113 and an air outlet 114 are provided between each fresh-keeping compartment 111 and the circulation air duct 112, so that the fresh-keeping compartment 111 is in fluid communication with the circulation air duct 112 through the air inlet 113 and the air outlet 114.

[0057] Continue reading Figures 1 to 3 The damper 150 can be arranged at the air inlet 113 or at the air outlet 114. In addition, those skilled in the art can also configure a damper 150 for each air inlet 113 and air outlet 114 as needed, and record the two dampers 150 corresponding to the same fresh-keeping compartment 111 as the same damper 150, so as to facilitate the understanding of the control method described below.

[0058] In the present invention, the damper 150 is an electrically controlled damper having a motor or driven by a motor, which can open or cover the air inlet 113 or the air outlet 114 in a rotating manner, and can also open or cover the air inlet 113 or the air outlet 114 in a sliding manner.

[0059] Furthermore, the gas conditioning device 130 is configured to transfer oxygen from the inside of the circulating air duct 112 to the outside, or transfer oxygen from the outside of the circulating air duct 112 to the inside, through an electrochemical reaction (please refer to the background art for details).

[0060] from Figures 1 to 3 As can be seen in the figure, the fan 140 can be arranged in the circulating air duct 112 so that the fan 140 can transport the air in the circulating air duct 112 to any fresh-keeping compartment 111.

[0061] In the present invention, the fan 140 can be any feasible fan such as a cross-flow fan, a centrifugal fan, an axial flow fan, etc.

[0062] like Figure 2 As shown, when oxygen is regulated in the fresh-keeping chamber 111 on the left side of the fresh-keeping device 100, the fan 140 drives the air to circulate between the circulating air duct and the fresh-keeping chamber 111 on the left side.

[0063] like Figure 3 As shown, when oxygen is regulated in the fresh-keeping chamber 111 on the right side of the fresh-keeping device 100 , the fan 140 drives the air to circulate between the circulating air duct and the fresh-keeping chamber 111 on the right side.

[0064] like Figures 1 to 3 As shown, in the present invention, the circulating air duct 112 can be defined as a meandering channel, and the air conditioning device 130 is disposed in the meandering channel.

[0065] Furthermore, the gas conditioning device 130 includes at least one electrode plate exposed in the meandering channel.

[0066] Those skilled in the art can understand that the above-mentioned features of the fresh-keeping device 100 can ensure that the gas conditioning device 130 consumes the oxygen in the meandering channel through the at least one electrode plate, or releases oxygen into the meandering channel.

[0067] Furthermore, at least one electrode plate is respectively disposed on two opposite sides of the gas conditioning device 130, so that two opposite channel sections of the meandering channel correspond to an electrode plate respectively.

[0068] Those skilled in the art can understand that the above-mentioned features of the fresh-keeping device 100 can increase the contact area between the gas conditioning device 130 and the oxygen in the meandering channel, and improve the oxygen conditioning efficiency of the gas conditioning device 130.

[0069] from Figures 1 to 3 It is not difficult to see that the meandering passage can be defined by the box body 110 and the air conditioning device 130, and the air conditioning device 130 is arranged on the inner side of the meandering passage.

[0070] Continue reading Figures 1 to 3 In the present invention, the gas conditioning device 130 includes a housing 131, a cathode plate 132 and an anode plate 133. The housing 131 has openings (not shown in the figure) on opposite sides, and a cathode plate 132 is disposed at each opening, so that the housing 131 and the cathode plate 132 define a cavity for containing electrolyte. The anode plate 133 is arranged in the housing 131.

[0071] Those skilled in the art can understand that, in the present invention, the cathode plate 132 is the above-mentioned electrode plate.

[0072] In addition, those skilled in the art may also set the electrode plate as the anode plate 133 as needed, that is, the anode plate 133 and the cathode plate 132 described above are interchanged.

[0073] Furthermore, although not shown in the figure, the housing 131 is also provided with an exhaust port, which leads to the outside of the fresh-keeping chamber 111 and the circulating air duct 112 to discharge the oxygen generated by the air conditioning device 130 to the outside.

[0074] Refer to the following Figures 1 to 3 The control method of the fresh-keeping device of the present invention is described in detail.

[0075] like Figure 4 As shown, in some embodiments of the present invention, the control method of the fresh-keeping device includes:

[0076] Step S110, in response to at least one door body 120 changing from an open state to a closed state, recorded as a first target door body, and controlling the air conditioning device 130 to operate.

[0077] Step S120 , in response to the air conditioning device 130 running for a first preset time period, the damper 150 corresponding to the first target door body is controlled to open, and the fan 140 is controlled to run.

[0078] Those skilled in the art can understand that, before the damper 150 corresponding to the first target door is opened, the air conditioning device 130 is operated for a first preset time, so that the oxygen concentration in the circulating air duct 112 is closer to the oxygen concentration in the fresh-keeping compartment 111 corresponding to the first target door. When the damper 150 corresponding to the first target door is opened and the fan 140 is operated, the air in the circulating air duct 112 can quickly enter the fresh-keeping compartment 111 and mix with the air in the fresh-keeping compartment 111, thereby quickly changing the oxygen concentration in the fresh-keeping compartment 111; thus, the efficiency of the fresh-keeping device 100 in regulating the oxygen concentration in the fresh-keeping compartment 111 is improved.

[0079] To achieve the above purpose, the first preset duration may be any feasible duration, such as 1 minute, 3 minutes, 5 minutes, 7 minutes, 10 minutes, etc.

[0080] Step S130, in response to reaching a preset condition, controlling the air conditioning device 130 and the fan 140 to stop running.

[0081] The preset condition may be that the oxygen concentration in all the fresh-keeping compartments 111 where the dampers 150 are in the open state has reached a preset threshold.

[0082] In the present invention, if the fresh-keeping compartment 111 needs to reduce oxygen (the gas conditioning device 130 is as follows Figures 1 to 3If the oxygen concentration does not reach the preset threshold, it means that the oxygen concentration is greater than the preset threshold. If the fresh-keeping compartment 111 needs to be oxygenated, the oxygen concentration does not reach the preset threshold, which means that the oxygen concentration is less than the preset threshold. For example, the preset threshold is 95%, 86%, 75%, 60%, 50%, etc. of the concentration of oxygen in the ambient air.

[0083] Based on the foregoing description, those skilled in the art will understand that, in some embodiments of the present invention, while automatically adjusting the oxygen concentration in the fresh-keeping compartment 111, the efficiency of the atmosphere-conditioning device 130 in adjusting the oxygen concentration in the corresponding fresh-keeping compartment 111 is improved by allowing the atmosphere-conditioning device 130 to run for a first preset time in advance.

[0084] It should be noted that the above-mentioned embodiment of the present invention is only a basic embodiment of the present invention. In other embodiments of the present invention, those skilled in the art may also adjust, optimize and configure the schemes and steps in the above-mentioned embodiments as needed to achieve further technical effects. Other embodiments of the present invention different from the above-mentioned embodiments will be described in conjunction with the accompanying drawings hereinafter. Of course, those skilled in the art may also make appropriate modifications to the execution order, operating conditions and quantity of the steps in the embodiments to be described hereinafter according to actual needs. The modified embodiments do not deviate from the technical concept and / or technical principle of the present invention and should still fall within the scope of protection of the present invention.

[0085] like Figure 5 As shown, in some other embodiments of the present invention, the control method of the fresh-keeping device further includes at least one of step S210, step S220 and step S230. The three steps are parallel steps.

[0086] Among them, step S210 is located after step S130 and includes: in response to the continuous failure to detect that the state of any door body 120 has changed, controlling the air conditioning device 130 to work for a third preset time period every second preset time period, and controlling the fan 140 to work for a fourth preset time period.

[0087] The second preset duration may be any feasible duration, such as 10 minutes, 12 minutes, 35 minutes, 48 ​​minutes, 60 minutes, etc.

[0088] The third preset duration may be any feasible duration, such as 1 minute, 3 minutes, 5 minutes, 7 minutes, 10 minutes, etc.

[0089] Among them, the fourth preset duration can be any feasible duration, such as 1 minute, 3 minutes, 5 minutes, 7 minutes, 10 minutes, etc.

[0090] In step S210, controlling the fan 140 to run for a fourth preset time period includes: controlling the fan 140 to run for a fourth preset time period at f% of the rated speed, where f is a positive number less than 100.

[0091] Further, the fourth preset time period may be equal to the third preset time period, and the fan 140 may operate simultaneously with the air conditioning device 130 .

[0092] Furthermore, in some other embodiments of the present invention, f=50.

[0093] In addition, those skilled in the art may also set f to any other feasible value, such as 45, 60, 65, 80, etc., as needed.

[0094] Those skilled in the art will appreciate that controlling the fan 140 to operate at f% of the rated speed can enable the fan 140 to maintain the oxygen concentration in the fresh-keeping compartment 111 at a lower speed.

[0095] Furthermore, those skilled in the art may also appropriately reduce the operating power of the gas conditioning device 130 as needed, for example, reducing the operating power of the gas conditioning device 130 to 95%, 80%, 75%, 60%, 45%, etc. of normal operation.

[0096] Wherein, step S220 includes: in response to the preset condition being met, controlling the fan 140 to stop running, and controlling the air conditioning device 130 to run for a fifth preset time period before stopping running.

[0097] Among them, the fifth preset duration can be any feasible duration, such as 1 minute, 3 minutes, 5 minutes, 7 minutes, 10 minutes, etc.

[0098] Those skilled in the art will appreciate that step S220 is intended to enable the circulating air duct 112 to further reduce or increase the oxygen concentration when the oxygen concentration in the fresh-keeping compartment 111 reaches a preset threshold, so that after the door 120 of a fresh-keeping compartment 111 is opened and closed, air with a corresponding oxygen concentration can be quickly provided to the fresh-keeping compartment 111, thereby quickly adjusting the oxygen in the fresh-keeping compartment 111.

[0099] Step S230, in response to at least one door body 120 changing from a closed state to an open state, recorded as a second target door body, and controlling the corresponding damper 150 to close.

[0100] It can be understood by those skilled in the art that when a certain door body 120 (i.e., the second target door body) is opened, by closing the corresponding damper 150, it is possible to prevent the outside air from convecting with other fresh-keeping compartments 111 through the fresh-keeping compartment 111 corresponding to the certain door body 120 (i.e., the second target door body), thereby ensuring the oxygen concentration in other fresh-keeping compartments 111.

[0101] Furthermore, although not shown in the figures, in some other embodiments of the present invention, compared with any of the embodiments described above, the control method of the fresh-keeping equipment may also include before step S110: in response to at least one door body 120 changing from a closed state to an open state, controlling the air conditioning device 130 and the fan 140 to stop working, and controlling all the dampers 150 to change to a closed state.

[0102] like Figure 6 As shown, in the present invention, the fresh-keeping device may further include a controller 160, which includes a memory 161 and a processor 162. The memory 161 stores a machine executable program 1611. When the processor 162 executes the machine executable program 1611, it can implement the control method described in any of the above embodiments.

[0103] The memory 161 may include a memory and a non-volatile memory, and provide execution instructions and data to the processor 162. For example, the memory may be a high-speed random access memory (RAM), and the non-volatile memory may be at least one disk storage.

[0104] The processor 162 is an integrated circuit chip that has the ability to process signals. The processor 162 can be a general-purpose processor, such as a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, microprocessors, and any other conventional processors.

[0105] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention will fall within the protection scope of the present invention.
