Detailed Description
Fig. 1 is a schematic structural view of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 of the present embodiment should be understood in a broad sense, and may be, for example, a storage device having a low-temperature fresh-keeping function such as the refrigerator 10, a freezer, a storage cabinet, or the like.
The refrigerator 10 may generally include a cabinet 100 and a gas treatment device 200. Wherein, a plurality of storage spaces are formed inside the case 100. The storage space of the present embodiment should be understood in a broad sense, and may be a space separated from each other. The "separation" may be complete or incomplete. For example, the storage space may refer to an inner space of the storage compartment, or an inner space of the storage container provided in the storage compartment, or a peripheral environment space 123 formed in the storage compartment and located outside the storage container.
Fig. 2 is a schematic structural view of a gas treatment device 200 of the refrigerator 10 according to one embodiment of the present invention. Fig. 3 is another schematic structural view of the gas treatment device 200 of the refrigerator 10 shown in fig. 2, with a portion of the electrode pairs omitted.
The gas treatment device 200 has a plurality of differently oriented electrode plate segments 242 such that each electrode plate segment 242 is respectively provided with a storage space in gas flow communication therewith, configured to treat a specific gas component of the storage space by an electrochemical reaction. That is, the gas treatment device 200 has a plurality of electrode plate sections 242, and the plurality of electrode plate sections 242 are oriented differently so as to be in gas flow communication with the storage spaces in different orientations, thereby adjusting the specific gas composition of the storage spaces. The gas treatment device 200 of the present embodiment treats specific gas components in the gas through electrochemical reaction of the electrode, so that the storage space forms a specific fresh-keeping environment.
The different orientations of the plurality of electrode plate segments 242 means that the plurality of electrode plate segments 242 are not in the same plane. For example, adjacent electrode plate segments 242 may be angled or curved, which facilitates that multiple electrode plate segments 242 may be oriented simultaneously toward and in gas flow communication with different storage spaces.
Because the plurality of storage spaces are provided in the case 100, the electrode plate sections 242 of the gas treatment device 200 are arranged in different orientations, which facilitates each electrode plate section 242 to be respectively in gas flow communication with the corresponding storage space, so that specific gas components in the storage space are treated through electrochemical reaction, therefore, the plurality of storage spaces can be simultaneously subjected to atmosphere adjustment by only providing one gas treatment device 200, the refrigerator 10 of the embodiment can realize one machine with multiple purposes of the gas treatment device 200, which is beneficial to simplifying the structure of the refrigerator 10 and improving the fresh-keeping performance.
In some alternative embodiments, each electrode plate segment 242 is provided with a respective counter electrode plate segment 222 to form a plurality of electrode pairs. That is, each electrode plate segment 242 has an opposite electrode plate segment disposed correspondingly thereto, respectively.
In some alternative embodiments, the polarity of the plurality of electrode plate segments 242 may be the same and the polarity of the plurality of counter electrode plate segments 222 may be the same, which may be advantageous to ensure consistency of the electrode plate segments 242 and consistency of the counter electrode plate segments 222, reducing or avoiding occurrence of confusion.
In each set of electrode pairs, the electrode plate segments 242 are of opposite polarity to the counter electrode segments 222 and may be either of an anode and a cathode, respectively.
Because each electrode plate segment 242 has a corresponding counter electrode plate segment to form a plurality of groups of electrode pairs, the two poles of each group of electrode pairs can respectively perform different electrochemical reactions and obtain different air conditioning effects, the flexibility of the air conditioning process of the gas treatment device 200 is improved based on the scheme of the embodiment.
By arranging the plurality of counter electrode plate sections 222 and enabling the plurality of counter electrode plate sections 222 to be opposite to the plurality of electrode plate sections 242 one by one, a plurality of groups of electrode pairs can be formed, and each group of electrode pairs can respectively and independently perform electrochemical reaction, so that the gas components of the corresponding storage space can be independently regulated, the gas treatment device 200 can adapt to different air conditioning requirements of the plurality of storage spaces, and the universality of the gas treatment device 200 can be improved.
Of course, in alternative embodiments, the polarities of the plurality of electrode plate segments 242 may not be identical, and the polarities of the plurality of counter electrode plate segments 222 may not be identical, so long as the polarities of the electrode plate segments 242 and the counter electrode plate segments 222 of each electrode pair are opposite, and the polarities of the electrode plate segments 242 in gas flow communication with the storage space may be set according to the actual air conditioning requirements of the storage space.
The structure of the refrigerator 10 will be further described by taking a case where the polarities of the plurality of electrode plate sections 242 are the same and the polarities of the plurality of counter electrode plate sections 222 are the same as an example. In some alternative embodiments, electrode plate segment 242 is a cathode and is configured to consume oxygen from the storage space by performing an electrochemical reaction under an electrolytic voltage. Counter electrode plate segment 222 is an anode and is configured to provide reactants to corresponding electrode plate segment 242 and generate oxygen by performing an electrochemical reaction under an electrolytic voltage.
Wherein the cathode is used for being connected with the cathode of the power supply and carrying out reduction reaction. The anode is used for being connected with the positive electrode of the power supply and carrying out oxidation reaction.
The gap between the electrode plate segment 242 and the counter electrode plate segment 222 forms an electrolyte chamber 230 for containing electrolyte. The electrolytic chamber 230 can contain alkaline electrolyte, such as NaOH or KOH of 0.1-8 mol/L, and the concentration can be adjusted according to actual needs.
Specific gas composition of the present embodimentThe partial oxygen refers to oxygen. For example, oxygen in air may undergo a reduction reaction at the cathode, namely: o (O) 2 +2H 2 O+4e - →4OH - . OH generated by cathode - An oxidation reaction may occur at the anode and oxygen is generated, namely: 4OH - →O 2 +2H 2 O+4e - . Anode using OH - While the electrochemical reaction takes place, a reactant, e.g. an electron e, is also supplied to the cathode - 。
Of course, the above examples of electrochemical reactions and equations thereof are merely illustrative, and those skilled in the art should readily adapt the refrigerator 10 of the present embodiment to other types of electrochemical reactions and processes for other types of specific gas components, such as electrochemical reactions for generating or consuming carbon dioxide, electrochemical reactions for generating or consuming nitrogen, electrochemical reactions for generating or consuming ethylene, etc., while understanding the embodiments, all of which fall within the scope of the present invention.
With the above structure, the gas treatment device 200 can treat the oxygen in the storage space of the refrigerator 10, so as to conform to the development concept of low-oxygen preservation, prolong the preservation period of food materials such as fruits and vegetables, and improve the preservation performance of the refrigerator 10.
Meanwhile, as the anode generates oxygen during electrochemical reaction, the oxygen can be utilized and can be conveyed to a high-oxygen space of the refrigerator 10, for example, the air conditioning capacity of the refrigerator 10 can be improved, and a low-oxygen fresh-keeping atmosphere and a high-oxygen fresh-keeping atmosphere can be simultaneously created.
Fig. 4 is a schematic view of an internal structure of the refrigerator 10 according to some embodiments of the present invention.
In some alternative embodiments, the storage space includes a peripheral environment space 123 and a first fresh-keeping space 121 disposed within the peripheral environment space 123. The first fresh-keeping space 121 is an independent space disposed in the peripheral environment space 123.
The plurality of electrode plate segments 242 includes a first fresh-keeping plate segment 242a and at least one conditioning plate segment. Wherein the first fresh-keeping plate section 242a is in air flow communication with the first fresh-keeping space 121. When the first fresh-keeping plate section 242a performs electrochemical reaction, oxygen in the first fresh-keeping space 121 can be used as a reactant, so as to achieve the purpose of reducing oxygen. At least one conditioning plate segment is in air flow communication with the ambient space 123. When the adjusting plate section performs electrochemical reaction, oxygen in the peripheral environment space 123 can be used as a reactant, and the counter electrode plate section 222 corresponding to the adjusting plate section can generate oxygen through electrochemical reaction.
When the oxygen content of the first fresh-keeping space 121 needs to be reduced, the electrolysis voltage of the electrode pair to which the first fresh-keeping plate section 242a belongs may be turned on. When the oxygen content in the first fresh-keeping space 121 needs to be increased, the electrolysis voltage of at least one electrode pair to which the adjusting plate section belongs may be turned on, and the oxygen generated by the counter electrode plate section 222 corresponding to the adjusting plate section may be led to the first fresh-keeping space 121.
For example, the gas treatment device 200 has an electrolysis chamber and a vent. The electrolytic cavity is used for containing electrolyte. The plurality of electrode pairs may share an electrolyte. The electrolyte can be alkaline, for example, naOH or KOH, and the concentration of the electrolyte can be set according to actual needs. The exhaust port communicates with the electrolysis chamber and is used to exhaust oxygen generated by the counter electrode plate segment 222. The refrigerator 10 may further include an air duct communicating the storage space with the electrolysis chamber for guiding oxygen discharged from the air outlet to the storage space. The storage space herein refers to a space in which an increase in oxygen content is required to create a high oxygen atmosphere.
In some alternative embodiments, the storage space further includes a second fresh-keeping space 122 located within the peripheral ambient space 123. The second fresh-keeping space 122 is a separate space disposed in the peripheral environment space 123. The plurality of electrode plate segments 242 also includes a second fresh-keeping plate segment 242b in airflow communication with the second fresh-keeping space 122. When the second fresh-keeping plate section 242b performs the electrochemical reaction, oxygen in the second fresh-keeping space 122 can be used as a reactant, so as to achieve the purpose of reducing oxygen.
When the oxygen content of the second fresh-keeping space 122 needs to be reduced, the electrolysis voltage of the electrode pair to which the second fresh-keeping plate section 242b belongs may be turned on. When the oxygen content in the second fresh-keeping space 122 needs to be increased, the electrolysis voltage of at least one electrode pair to which the adjusting plate section belongs can be turned on, and the oxygen generated by the counter electrode plate section 222 corresponding to the adjusting plate section can be guided to the second fresh-keeping space 122.
That is, the conditioning plate segment and its counter electrode plate segment 222 are configured to controllably switch on the electrolysis voltage when the first fresh food space 121 and/or the second fresh food space 122 increases the oxygen content. That is, when any one or more of the first fresh-keeping space 121 and the second fresh-keeping space 122 needs to increase the oxygen content, the electrolysis voltage of at least one of the adjusting plate sections may be turned on to supply oxygen to the first fresh-keeping space 121 and/or the second fresh-keeping space 122.
Because the first fresh-keeping space 121 and the second fresh-keeping space 122 can respectively utilize the respective corresponding fresh-keeping plate segments to reduce the oxygen content, and can also utilize the adjusting plate segments and the electrochemical reaction of the adjusting plate segments to the plate electrode segments 222 to improve the oxygen content, the refrigerator 10 can flexibly improve or reduce the oxygen content of the storage space based on the scheme of the embodiment, which is beneficial to realizing the functional multiplexing of the storage space, so as to meet the storage requirements of users at different occasions, improve the space utilization rate and optimize the use experience of the users.
In some further embodiments, the adjusting plate section is greater than or equal to two, for example, two, three, or four. Because the adjusting plate sections are more than or equal to two, different oxygen generation rates can be obtained by selecting different amounts of adjusting plate sections to start electrochemical reaction, and therefore, based on the scheme of the embodiment, the refrigerator 10 can adjust the oxygen rising rate of the storage space, and further improve the fresh-keeping performance.
In some alternative embodiments, the plurality of electrode plate segments 242 and the plurality of counter electrode plate segments 222 each enclose a hollow quadrangular prism. The hollow quadrangular prism body where the electrode plate section 242 is located is sleeved outside the hollow quadrangular prism body where the counter electrode plate section 222 is located.
Because the plurality of electrode plate sections 242 and the plurality of counter electrode plate sections 222 respectively enclose into the hollow quadrangular prism, and the hollow quadrangular prism in which the electrode plate sections 242 are located is sleeved outside the hollow quadrangular prism in which the counter electrode plate sections 222 are located, therefore, the electrode plate sections 242 are opposite to each other, when the gas treatment device 200 is arranged between the storage spaces arranged in parallel in pairs, each storage space can be opposite to one electrode plate section 242 respectively, and the unique structure of the gas treatment device 200 can be perfectly matched with the layout structure of the storage space of the refrigerator 10, so that the structure is ingenious, the gas path structure is reduced, and the space layout of the refrigerator 10 is optimized.
For example, in some alternative embodiments, the first fresh food compartment 121 is laterally juxtaposed with the second fresh food compartment 122. The hollow quadrangular prism in which the counter electrode plate section 222 is located is disposed between the first fresh-keeping space 121 and the second fresh-keeping space 122, and the first fresh-keeping plate section 242a and the second fresh-keeping plate section 242b are distributed on two lateral sides of the hollow quadrangular prism so as to be respectively in airflow communication with the first fresh-keeping space 121 and the second fresh-keeping space 122.
Of course, the spatial layout of the refrigerator 10 is not limited thereto. For example, in alternative embodiments, the first fresh-keeping space 121 and the second fresh-keeping space 122 are juxtaposed one above the other. The hollow quadrangular prism in which the counter electrode plate section 222 is located is disposed between the first fresh-keeping space 121 and the second fresh-keeping space 122, and the first fresh-keeping plate section 242a and the second fresh-keeping plate section 242b are distributed on the upper and lower sides of the hollow quadrangular prism so as to be respectively in airflow communication with the first fresh-keeping space 121 and the second fresh-keeping space 122.
The gap between the electrode plate segment 242 and the counter electrode plate segment 222 forms an electrolyte chamber for containing electrolyte. In some alternative embodiments, the gas treatment device 200 further comprises a first enclosure and a second enclosure. The first protection frame is hollow quadrangular and is sleeved outside the hollow prism where the electrode plate section 242 is located. The second protection frame is also in a hollow prismatic shape and is sleeved inside or outside the hollow prismatic body where the counter electrode plate section 222 is located. And the first and second shield frames close the gap between the electrode plate segment 242 and the counter electrode plate segment 222.
The first and second shield frames are used to protect the electrode plate sections 242 and the counter electrode plate sections 222, respectively, which can improve the structural strength of the gas treatment device 200 to some extent and reduce or avoid leakage of electrolyte. In some further embodiments, ventilation holes for allowing gas to pass through may be formed in the first protective frame, so as to avoid completely shielding the electrode plate section 242, and ensure normal operation of the air conditioning process.
In some alternative embodiments, the first fresh-keeping space 121 and the second fresh-keeping space 122 may be storage drawers, respectively, and the walls of the drawers are provided with ventilation areas so as to be in airflow communication with the corresponding electrode plate sections 242. For example, the electrode plate segments 242 may cover the side of the venting area facing away from the drawer interior space, thereby shielding the venting area. The ventilation zone may be formed by means of a perforation or an opening.
It should be noted that, although the plurality of electrode plate sections 242 and the plurality of counter electrode plate sections 222 respectively enclose a hollow quadrangular prism, it does not mean that the electrode plate sections 242 are disposed in each face of the hollow quadrangular prism in which the electrode plate sections 242 are located, and that the counter electrode plate sections 222 are disposed in each face of the hollow quadrangular prism in which the counter electrode plate sections 222 are located.
As shown in fig. 4, the number and positions of the electrode plate segments 242 and the counter electrode plate segments 222 may be adjusted according to actual needs. Fig. 4 (a) shows an assembly between the gas treatment device 200 having four sets of electrode pairs and a storage space, and the electrode plate section 242 of the gas treatment device 200 includes a first fresh-keeping plate section 242a, a second fresh-keeping plate section 242b, and two adjustment plate sections. In comparison with fig. 4 (a), fig. 4 (b) omits one adjusting plate section and its counter electrode plate section 222, fig. 4 (c) omits all adjusting plate sections and its counter electrode plate section 222, and fig. 4 (d) omits the first fresh-keeping plate section 242a and the second fresh-keeping plate section 242b.
Fig. 5 is a schematic diagram of a power supply circuit 300 of a gas treatment device 200 of a refrigerator 10 according to some embodiments of the present invention, showing three different power supply configurations of the gas treatment device 200 having four electrode pairs.
In some alternative embodiments, the refrigerator 10 further includes a power supply circuit 300 configured to provide the electrolytic voltage required for performing the electrochemical reaction to the plurality of electrode pairs, and the power supply circuit 300 is provided with a plurality of switching components connected to each of the plurality of electrode pairs in a one-to-one correspondence, and configured to be controlled to be opened and closed to adjust the on-off state between the corresponding electrode pairs and the power supply circuit 300.
That is, the on-off state between each electrode pair and the power supply circuit 300 is controlled by the corresponding switching assembly, respectively. Since the on-off state between the electrode pair and the power supply circuit 300 directly determines whether the electrode pair turns on the electrolytic voltage, by controlling the on-off state of the switching element, it is possible to control whether the electrochemical reaction is started for the corresponding electrode pair. Based on this, refrigerator 10 can select one or more of the plurality of electrode pairs to start electrochemical reaction according to actual needs, and flexibility is high.

In some embodiments, the gas treatment apparatus 200 further comprises a first enclosure 212 and a second enclosure 214. The first protection frame 212 is in a hollow prism shape and is sleeved outside the hollow prism body where the electrode plate section 242 is located. The second protection frame 214 is also in a hollow prism shape, and is sleeved in the hollow prism body where the counter electrode plate section 222 is located.
The first and second protective frames 212 and 214 are used to protect the electrode plate sections 242 and 222, respectively, which can improve the structural strength of the gas treatment device 200 to some extent and reduce or avoid leakage of electrolyte. In some further embodiments, ventilation holes for allowing gas to pass through may be formed in the first protective frame 212, so as to avoid completely shielding the electrode plate section 242, and ensure that the air conditioning process is performed normally.
It should be noted that the first protective frame 212 and the second protective frame 214 also serve as an integration function, so that the electrode plate section 242 and the counter electrode plate section 222, which are separately disposed, are assembled into a whole.
In some alternative embodiments, the gas treatment device 200 may further include a first enclosure 216 and a second enclosure 218.
Wherein the first closure portion 216 closes a gap between the first end of the electrode plate segment 242 and the first end of the counter electrode plate segment 222. The second closure 218 closes a gap between the second end of the electrode plate segment 242 and the second end of the counter electrode plate segment 222. That is, the first closing portion 216 and the second closing portion 218 close the gaps between the electrode plate section 242 and the opposite electrode plate section 222, respectively, to close the electrolytic chamber 230.
In some alternative embodiments, the first sealing portion 216 and the second sealing portion 218 may have a ring cover plate shape, respectively, to seal gaps between two ends of the multi-surface electrode and the multi-surface counter electrode, and may be connected to the multi-surface electrode and the multi-surface counter electrode by riveting, welding, screwing, clamping, or bonding, respectively, in any manner.
In the above embodiments, the opposite electrode plate segment 222 forms an air flow channel 250 for air flow therethrough on the side facing away from the electrode plate segment 242. When the counter electrode plate segment 222 is a cathode and the electrode plate segment 242 is an anode, the gas to be treated can flow along the extending direction of the gas flow channel 250, and oxygen in the gas continuously participates in the electrochemical reaction and is consumed in the flowing process, so that the gas flowing out of the gas flow channel 250 contains little oxygen, the air conditioning effect is enhanced, the time required by air conditioning is reduced, and the circulation times of the gas flow are reduced. The air conditioning requirement of the storage space may be satisfied by performing only one or a small number of air circulation cycles between the storage space of the refrigerator 10 and the air treatment device 200.
In the refrigerator 10 of the present invention, since the plurality of storage spaces are provided in the case 100, the electrode plate sections 242 of the gas treatment device 200 are disposed to face different directions, which facilitates each electrode plate section 242 to be respectively in gas flow communication with the corresponding storage space, thereby treating specific gas components of the storage space through electrochemical reaction, therefore, the plurality of storage spaces can be simultaneously subjected to atmosphere adjustment by only providing one gas treatment device 200, and the refrigerator 10 of the present invention can realize one machine with multiple purposes of the gas treatment device 200, which is beneficial to simplifying the structure of the refrigerator 10 and improving the fresh-keeping performance.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
