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-conditioning device in the existing fresh-keeping equipment cannot perform atmosphere-conditioning for multiple fresh-keeping compartments.

[0007] One purpose of the present invention is to sequentially regulate oxygen in all fresh-keeping compartments.

[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] Determine whether there is a target damper in an open state among all the dampers, and the oxygen concentration in the fresh-keeping room corresponding to the target damper does not reach a preset threshold;

[0010] If present, all the target dampers are prioritized to determine the oxygen adjustment order;

[0011] The operation of the air conditioning device and the fan is controlled, and each of the target dampers is opened successively according to the oxygen adjustment sequence until the preset conditions are met.

[0012] Optionally, the step of determining whether there is a target damper in an open state among all the dampers includes:

[0014] Determine a priority list of all the door bodies in a closed state from the oxygen adjustment priority list, and record it as a first priority list;

[0015] Determining a priority list of all the dampers in an open state from the first priority list and recording it as a second priority list;

[0016] A determination is made as to whether the target damper exists in the second priority list.

[0017] Optionally, the control method further includes:

[0018] In response to detecting that a state change has occurred in at least one of the door bodies, state information of at least one of the door bodies in the oxygen adjustment priority list is updated.

[0019] Optionally, the control method further includes:

[0020] In response to detecting that a state change has occurred in at least one of the door bodies, controlling the corresponding damper to open or close to adapt to the state change of the door body;

[0021] Update the status information of the corresponding damper in the oxygen adjustment priority list.

[0022] Optionally, the control method further includes:

[0023] In response to receiving the priority setting instruction, the priority information of all the fresh-keeping compartments in the oxygen regulation priority list is updated according to the priority setting instruction.

[0024] Optionally, the step of opening each of the target dampers in sequence according to the oxygen adjustment sequence until a preset condition is met includes:

[0025] Opening each of the target air doors one by one according to the oxygen adjustment sequence, and closing all other target air doors when opening each of the target air doors;

[0026] When the current target damper is opened for the first preset time, or when the oxygen concentration in the fresh-keeping room corresponding to the current target damper reaches the preset threshold, the current target damper is closed and the next target damper is opened until all the target dampers are opened.

[0027] Optionally, after the preset condition is met, the control method further includes:

[0028] The fan is controlled to stop running, and the air conditioning device is controlled to continue running for a second preset time period.

[0029] Optionally, the fresh-keeping device is a refrigerator.

[0030] In a second aspect, the present invention provides a fresh-keeping device, comprising:

[0031] The box body is defined with at least two fresh-keeping compartments;

[0032] At least two door bodies, each of which corresponds to one of the fresh-keeping compartments;

[0035] 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;

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Furthermore, by determining whether there is a target damper in an open state among all dampers, and if there is, all target dampers are prioritized to determine the oxygen adjustment order. Then, by controlling the operation of the air conditioning device and the fan, each target damper is opened one by one in the oxygen adjustment order until the preset conditions are met. Therefore, the present invention can also adjust the oxygen of all fresh-keeping spaces in sequence according to the priority order of oxygen adjustment.

[0040] 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.

[0054] 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.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0056] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

It should be understood by those skilled in the art 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 are changed, they will not deviate from the technical principle of the present invention, and therefore should fall within the protection scope of the present invention.

[0059] 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.

[0060] 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 .

[0061] The fresh-keeping chamber 111 is used to store food so that the fresh-keeping device 100 can keep the food fresh.

[0062] The door body 120 is used to shield the fresh-keeping compartment 111, thereby isolating the fresh-keeping compartment 111 from the external environment.

[0063] 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).

[0064] 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 .

[0065] 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.

[0066] 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 .

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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).

[0071] from Figures 1 to 3As 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] Furthermore, the gas conditioning device 130 includes at least one electrode plate exposed in the meandering channel.

[0077] 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.

[0078] 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.

[0079] 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.

[0080] 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.

[0081] Continue reading Figures 1 to 3In 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 each opening is provided with a cathode plate 132, so that the housing 131 and the cathode plate 132 together define a cavity for accommodating the electrolyte. The anode plate 133 is arranged in the housing 131.

[0082] Those skilled in the art can understand that, in the present invention, the cathode plate 132 is the above-mentioned electrode plate.

[0083] 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.

[0084] 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 compartment 111 and the circulating air duct 112 to discharge the oxygen generated by the air conditioning device 130 to the outside.

[0085] Refer to the following Figures 1 to 3 The control method of the fresh-keeping device of the present invention is described in detail.

[0086] like Figure 4 As shown, in some embodiments of the present invention, the control method of the fresh-keeping device includes:

[0087] Step S110, determining whether there is a target damper in an open state among all dampers 150, and the oxygen concentration in the fresh-keeping compartment 111 corresponding to the target damper does not reach a preset threshold.

[0088] In the present invention, the damper 150 which is in an open state and whose oxygen concentration in the corresponding fresh-keeping compartment 111 does not reach a preset threshold is recorded as a target damper.

[0089] 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 3 If the fresh-keeping compartment 111 needs oxygenation, then if 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 oxygenation, then if the oxygen concentration does not reach the preset threshold, it means that the oxygen concentration is less than the preset threshold.

[0090] In the present invention, all the fresh-keeping compartments 111 may correspond to the same preset threshold value, or may correspond to different preset threshold values. For example, each fresh-keeping compartment 111 corresponds to a preset threshold value.

[0091] Furthermore, the preset threshold value may be set by a user, or may be pre-stored on the fresh-keeping device 100 or a device that is in communication with the fresh-keeping device 100. The preset threshold value may be equal to the concentration value of oxygen in the ambient air, may be less than the concentration value of oxygen in the ambient air, or may be greater than the concentration value of oxygen in the ambient air. For example, the preset threshold value is 95%, 86%, 75%, 60%, 50%, etc. of the concentration value of oxygen in the ambient air.

[0092] Step S120: If present, prioritize all target dampers to determine the oxygen adjustment order.

[0093] The oxygen adjustment sequence is the sequence for adjusting the oxygen of all the fresh-keeping compartments 111 whose oxygen concentrations are to be adjusted.

[0094] Step S130, controlling the operation of the air conditioning device 130 and the fan 140, and opening each target damper in sequence according to the oxygen adjustment sequence until the preset conditions are met.

[0095] The preset condition may be that the oxygen concentration in each fresh-keeping compartment 111 reaches a preset threshold.

[0096] like Figure 5 As shown, in some embodiments of the present invention, step S110 may further include:

[0097] Step S111 , obtaining an oxygen adjustment priority list, which includes priority information of each fresh-keeping compartment 111 , status information of each door body 120 , and status information of each damper 150 .

[0098] The present invention provides an oxygen regulation priority list such as Figure 6 As shown. Figure 6 In the figure, A represents the priority, R represents the fresh-keeping compartment 111 , D represents the door body 120 , and S represents the damper 150 .

[0099] In the present invention, Figures 6 to 8 The shown list is intended to help those skilled in the art understand the technical solution of the present invention.

[0100] Preferably, in some embodiments of the present invention, the priority information of the fresh-keeping compartment 111 can be input by a user into the fresh-keeping device 100 and stored by the fresh-keeping device 100. Each door body 120 and each damper 150 are respectively configured with a separate sensor, so that the door body 120 and the damper 150 determine their status information through their respective corresponding sensors.

[0101] Furthermore, in some embodiments of the present invention, the fresh-keeping device 100 obtains signals from sensors corresponding to each door body 120 and each damper 150 in real time, so as to obtain status information of each door body 120 and status information of each damper 150 in real time, thereby updating when the status of the door body 120 and / or the damper 150 changes.

[0102] Step S112, determining a priority list of all doors 120 in a closed state from the oxygen adjustment priority list, and recording it as a first priority list.

[0103] For example, based on Figure 6 The oxygen priority list shown in Figure 7 First priority list shown.

[0104] Step S113, determining a priority list of all dampers 150 in the open state from the first priority list and recording it as a second priority list.

[0105] For example, based on Figure 7 The first priority list shown in Figure 8 The second priority list is shown.

[0106] Step S114, determining whether there is a target damper in the second priority list.

[0107] Specifically, it is determined whether the oxygen concentration in the fresh-keeping compartment 111 corresponding to each damper 150 in the second priority list has not reached a preset threshold, and if it is less than a preset threshold, the corresponding damper 150 in the second priority list is determined as a target damper.

[0108] like Fig. 9 As shown, in some embodiments of the present invention, step S130 may further include:

[0109] Step S131, opening each target air damper in sequence according to the oxygen adjustment sequence, and when opening each target air damper, closing all other target air dampers.

[0110] For example, Figure 8 The S1 damper 150 and the S3 damper 150 shown in the figure are target dampers. Then, according to the oxygen adjustment sequence, the S1 damper 150 is opened first, and the S2 damper 150 and the S3 damper 150 are closed; when the oxygen concentration in the R1 fresh-keeping compartment 111 reaches a preset threshold, the S1 damper 150 and the S2 damper 150 are closed, and the S3 damper 150 is opened.

[0111] Step S132, when the current target damper is opened for the first preset time, or when the oxygen concentration in the fresh-keeping compartment 111 corresponding to the current target damper reaches the preset threshold, the current target damper is closed and the next target damper is opened until all target dampers are opened, that is, until the oxygen concentration in all fresh-keeping compartments 111 reaches the preset threshold.

[0112] In some embodiments of the present invention, when the current target damper is opened for the first preset time period, it can be determined that the oxygen concentration in the corresponding fresh-keeping compartment 111 has reached a preset threshold.

[0113] The first preset duration may be any feasible duration, such as 2 minutes, 3 minutes, 5 minutes, 10 minutes, etc.

[0114] Based on the above description, it can be understood by those skilled in the art that, in some embodiments of the present invention, by driving the air fan 140 to flow between the fresh-keeping compartment 111 and at least two air conditioning devices 130, the air conditioning device 130 can adjust the oxygen concentration in the at least two fresh-keeping compartments 111 through an electrochemical reaction. By making the fresh-keeping compartment 111, the damper 150 and the door body 120 correspond to each other, and controlling whether the air in the corresponding fresh-keeping compartment 111 flows to the air conditioning device 130 through the damper 150, the fresh-keeping device 100 can control which fresh-keeping compartment 111 the air conditioning device 130 adjusts oxygen through the damper 150. Therefore, the fresh-keeping device 100 in the present invention can adjust the air of multiple fresh-keeping compartments 111 through the same air conditioning device 130.

[0115] Furthermore, by determining whether there is a target damper in the open state among all dampers 150, and if there is, all target dampers are prioritized to determine the oxygen adjustment order. Then, by controlling the operation of the air conditioning device 130 and the fan 140, each target damper is opened one by one in the oxygen adjustment order until the preset conditions are met. Therefore, the present invention can also adjust the oxygen of all fresh-keeping spaces in sequence according to the priority order of oxygen adjustment.

[0116] 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.

[0117] like Fig.10 As shown, in some further embodiments of the present invention, compared with some embodiments described above, the control method of the fresh-keeping device further includes:

[0118] Step S210: in response to detecting that a state change of at least one door body 120 occurs, updating state information of at least one door body 120 in the oxygen adjustment priority list.

[0119] Step S220 , in response to detecting that a state change of at least one door body 120 has occurred, controlling the corresponding damper 150 to open or close to adapt to the state change of the door body 120 .

[0120] Those skilled in the art can understand that when a certain door 120 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 120, thereby ensuring the oxygen concentration of other fresh-keeping compartments 111. When a certain door 120 is closed, by opening the corresponding damper 150, the fresh-keeping compartment 111 corresponding to the certain door 120 can quickly receive air with a higher or lower oxygen concentration, thereby quickly adjusting its own oxygen concentration.

[0121] Step S230, updating the status information of the corresponding damper 150 in the oxygen adjustment priority list.

[0122] Among them, step S210 and step S220 are parallel steps.

[0123] Those skilled in the art can understand that, compared with some of the embodiments described above, some other embodiments of the present invention can enable the fresh-keeping device 100 to quickly update the atmosphere adjustment sequence when the state of the door body 120 changes, thereby ensuring the atmosphere adjustment effect of the fresh-keeping device 100.
