Technical Field
[0001] This application relates to the field of refrigeration equipment technology, and in particular to an oxygen regulating component and a refrigeration device equipped with the oxygen regulating component. Background Technology
[0002] The electrolysis module is ventilated inside the protective box. Because the surface area of the conductive plate in the electrolysis module is large, but the air inlet and outlet of the protective box are small, it is easy to cause the air volume in the middle of the conductive plate to be larger and the air volume around the perimeter to be smaller. The uneven air volume of the conductive plate in contact with the air results in uneven lifespan of the conductive plate, which in turn leads to low reaction efficiency of the conductive plate. Summary of the Invention
[0003] The purpose of this application is to provide an oxygen regulation component and a refrigeration device. The oxygen regulation component divides the airflow entering the protective box into at least two streams through the air guide ribs, so that the airflow can pass through the electrolysis module evenly.

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0028] The terms used in this document, such as “center,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” indicating spatial relative positions, are used for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative positions” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.
[0029] For example, if the device in the figure is flipped, a unit described as being "below" or "under" other units or features will be "above" other units or features. Therefore, the exemplary term "below" can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or otherwise), and the spatially related descriptive terms used herein will be interpreted accordingly.
[0030] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0031] Furthermore, it should be understood that although the terms "first," "second," etc., may be used herein to describe various elements or structures, the objects being described should not be limited by these terms. These terms are only used to distinguish these objects from one another. For example, a first air inlet may be referred to as a second air inlet, and similarly, a second air inlet may be referred to as a first air inlet, without departing from the scope of protection of this application.
[0032] This application provides an oxygen regulation component, such as... Figures 1-9 As shown, the device includes a protective box 1, an electrolysis module disposed within the protective box 1, and at least two air passages 3 formed between the protective box 1 and the electrolysis module. The protective box 1 is provided with a first air inlet 11 and a first air outlet 12. The at least two air passages 3 are connected in parallel between the first air inlet 11 and the first air outlet 12. After the airflow enters the protective box 1 from the first air inlet 11, it is diverted to the aforementioned at least two air passages 3 and then converges and flows out from the first air outlet 12.
[0033] like Figure 3 In this electrolysis module, a shell with an oxygen-generating chamber 23 and a conductive plate 24 disposed within the oxygen-generating chamber 23 are included. The oxygen-generating chamber 23 is used to store electrolyte. The conductive plate includes an anode conductive plate and a cathode conductive plate, both at least partially immersed in the electrolyte. The anode conductive plate is connected to the positive terminal of the power supply, and the cathode conductive plate is connected to the negative terminal. After being connected to the power supply, the cathode conductive plate absorbs oxygen from the air and undergoes a reduction reaction, the reaction being O2 + 2H2O + 4e-. - →4OH - This makes the air flowing through the cathode conductive plate an oxygen-deficient, oxygen-regulated flow, while the anode conductive plate passes through the OH- in the electrolyte. - An oxidation reaction occurs, producing oxygen gas. The reaction equation is 4OH⁻. - →O2 + 2H2O + 4e - This produces an oxygen-enriched, regulated oxygen flow. The housing includes a first housing 21 and a second housing 22, with an oxygen-generating chamber 23 formed between the first housing 21 and the second housing 22. Both the first housing 21 and the second housing 22 are equipped with adsorption ports. An anode conductive plate / cathode conductive plate ( Figure 3At position 24 (the part) is exposed to the air passage 3 formed between the protective box 1 and the electrolysis module through the adsorption port, so as to deliver oxygen to the air passage 3 or adsorb oxygen from the air.
[0034] Figure 3 The conductive plates 24 provided at the adsorption ports of the first shell 21 and the second shell 22 have the same electrodes, that is, they are both cathode conductive plates or both anode conductive plates, in order to increase the oxygen exchange area and improve the electrolysis efficiency.
[0035] The oxygen regulation component provided in this application sets at least two air passages 3 between the protective box 1 and the electrolysis module, so that the air flowing through the air passage 3 can come into more full contact with the anode conductive plate / cathode conductive plate (hereinafter collectively referred to as conductive plate 24) exposed in the air passage 3, making the lifespan of the conductive plate 24 more uniform and the reaction efficiency of the electrolysis module better.
[0036] In some embodiments, the first air inlet 11 and the first air outlet 12 are disposed on the same side of the protective box 1, and a baffle 13 is provided inwardly on the side of the protective box 1 where the first air inlet 11 and the first air outlet 12 are disposed. The baffle 13 cooperates with the electrolysis module to divide the air passage 3 in the protective box 1 into a U-shaped air passage 3.
[0037] like Figure 3 In the first air inlet 11 and the first air outlet 12 are located on the top of the protective box 1. The baffle 13 extends downward until it is close to one side of the electrolysis module, so that after the air enters from the first air inlet 11, it cannot pass through the space at the top of the electrolysis module. Instead, it can only flow along one side of the electrolysis module due to the obstruction of the baffle 13 and the electrolysis module. The air flows through the conductive plate 24 set at the adsorption port, where oxygen exchange occurs. Then it flows through the gap between the bottom of the electrolysis module and the bottom of the protective box 1 to the other side of the electrolysis module. Since the electrodes of the conductive plates 24 on both sides are the same, oxygen exchange occurs in the same direction. The U-shaped air path 3 improves the electrolysis efficiency.
[0038] In some embodiments, the oxygen regulation assembly further includes air guide ribs 4, which are disposed between the protective box 1 and the electrolysis module, dividing the U-shaped air path 3 into at least two paths. The air guide ribs 4 extend generally along the air flow direction in the air path 3, preferably in multiple configurations, with multiple air guide ribs 4 spaced apart along the width direction of the air path 3 to guide the central airflow to the edges, maximizing the airflow through every corner and achieving uniform airflow to the conductive plate 24 at the adsorption port.
[0039] In some embodiments, such as Figure 5 , 6In the protective box 1, the air guide rib 4 is arranged along the thickness direction of the electrolysis module. The air guide rib 4 is located on the side opposite to the side where the first air inlet 11 and the first air outlet 12 are located. Corresponding to the fact that the first air inlet 11 and the first air outlet 12 are located at the top of the protective box 1, the air guide rib 4 is located at the bottom opposite to the top. After the air enters the protective box 1 through the first air inlet 11, it flows downward on one side of the electrolysis module. After the air flows to the bottom, it is diverted by the air guide rib 4 and turns from the bottom of the electrolysis module to the other side along the extension direction of the air guide rib 4.
[0040] In some embodiments, a boss 25 is provided at the bottom of the electrolysis module corresponding to the position of the air guide rib 4, and the electrolysis module is mounted on the air guide rib 4 through the boss 25. Providing a boss 25 at the bottom of the electrolysis module and mounting the electrolysis module on the air guide rib 4 through the boss 25 can increase the height between the bottom of the electrolysis module and the bottom of the protective box 1, allowing air to flow through.
[0041] In some embodiments, an air passage 3 is formed between the conductive plate 24 and the inner wall of the protective box 1. In the thickness direction of the conductive plate 24, the housing (first housing 21 or second housing 22) protrudes from the conductive plate 24. As previously shown, conductive plates 24 exposed to the air passage 3 are provided on both sides of the electrolytic module; that is, the space between the conductive plate 24 and the inner wall of the protective box 1 forms part of the air passage 3. Since the housing (first housing 21 or second housing 22) is located on the four sides of the conductive plate 24 and protrudes from the conductive plate 24, as... Figure 4 In the process, a height difference of air passage 3 is formed at the connection between the conductive plate 24 and the shell (first shell 21 or second shell 22) (which can also be called a thickness difference in the thickness direction of the conductive plate 24). When the air flows through the difference, it will form a vortex at the difference. The air can stay at the difference for a longer time due to the vortex. The thickness difference formed between the conductive plate 24 and the shell (first shell 21 or second shell 22) is the edge of the conductive plate 24, which happens to be the place where the air flow is less. The formation of vortex at the edge of the conductive plate 24 can effectively solve the problem of short life in the middle and long life at the edge of the conductive plate 24 caused by less air flow at the edge of the conductive plate 24.
[0042] In some embodiments, the protective box 1 is further provided with an air guide plate 14, which is disposed near the first air inlet 11 and inclined toward the electrolysis module. Figure 3In the protective box 1, there are a receiving chamber, an air inlet chamber 16, a liquid replenishment chamber 17, and a water washing chamber 18. The electrolysis module is disposed in the receiving chamber. The air inlet chamber 16, the water washing chamber 18, and the liquid replenishment chamber 17 are arranged vertically from top to bottom, and then arranged horizontally with the receiving chamber. The top of the water washing chamber 18 extends obliquely downwards towards the electrolysis module. The first air inlet 11 is connected to the top of the air inlet chamber 16. The aforementioned baffle 13 separates the top of the receiving chamber from the air inlet chamber 16. The gap for air intake in the receiving chamber is smaller, while the gap in the air inlet chamber 16 is larger. After the air enters the air inlet chamber 16 from the first air inlet 11, it is guided into the receiving chamber by the air guide plate 14 and the top of the obliquely arranged water washing chamber 18, thus preventing the airflow from being disturbed in the air inlet chamber 16.
[0043] A guide rib 4 is also provided on the side of the washing chamber 18 near the receiving chamber. When air enters the air intake chamber 16 from the first air inlet 11, it flows to the gap between the receiving chamber and the washing chamber 18 for air intake under the guidance of the guide plate 14. Here, under the action of the guide rib 4, the air is directed to both sides of the width direction of the air intake, so that the conductive plate 24 can obtain a larger air volume on both sides.
[0044] In some embodiments, the first air inlet 11 and the first air outlet 12 are located at the middle of the electrolysis module along its length. Since the length direction of the electrolysis module is horizontal and the width direction is vertical in the figures of this application, and the first air inlet 11 and the first air outlet 12 are located at the top of the protective box 1, i.e., the first air inlet 11 and the first air outlet 12 are located on the surface along the length of the electrolysis module, placing the first air inlet 11 and the first air outlet 12 at the middle of the electrolysis module allows air to flow more evenly through the conductive plate 24.
[0045] In some embodiments, the oxygen regulation component provided in this application further includes a ventilation module. The ventilation module includes a ventilation hood 5 and a fan disposed within the ventilation hood 5. The ventilation hood 5 is provided with an air inlet channel 51 communicating with the first air inlet 11 and an air outlet channel 53 communicating with the first air outlet 12. The air inlet channel 51 and the air outlet channel 53 are isolated from each other. The ventilation hood 5 is provided with a second air inlet 52 communicating with the first air inlet 11 through the air inlet channel 51, and a second air outlet 54 communicating with the first air outlet 12 through the air outlet channel 53. The ventilation hood 5 is provided with a volute 55 at the first air outlet 12, and a fan (not shown) is disposed within the volute 55. Air is sequentially passed through the second air inlet 52, the air inlet channel 51, and the first air inlet 11 into the protective box 1. After passing through the U-shaped air path 3, air is then sequentially blown out through the first air outlet 12, the air outlet channel 53, and the second air outlet 54 under the action of the fan.
[0046] In other embodiments, the first air inlet 11 and the first air outlet 12 are respectively located on two opposite sides of the protective box 1. Figure 8 , 9 In the middle, the left end is the first air inlet 11 and the right end is the first air outlet 12, or it can be that the left end is the first air outlet 12 and the right end is the first air inlet 11. This application does not impose any restrictions, therefore, it is not specified in the text. Figure 9 The diagram is shown in the image.
[0047] The first air inlet 11 and the first air outlet 12 are located at both ends along the length of the protective box 1. The electrolysis module inside the protective box 1 is spaced apart from the inner walls of the protective box 1 on both sides. That is, two air paths 3 are formed between the inner walls of the protective box 1 on both sides of the electrolysis module. After the air enters one end of the protective box 1 from the first air inlet 11, it is divided into two air paths 3 by the spacing of the electrolysis module itself. Finally, they converge at the other end and are blown out from the first air outlet 12. By utilizing the positional relationship between the protective box 1 and the electrolysis module, the cavity inside the protective box 1 is divided into two air paths 3, so that the air can flow evenly through the conductive plate 24, and the oxygen adjustment component has a simple structure.
[0048] This application embodiment also provides a refrigeration device, including a box having a refrigeration chamber and an oxygen regulating component disposed in the box and communicating with the refrigeration chamber. The oxygen regulating component is the aforementioned oxygen regulating component, used to provide a high-oxygen environment or a low-oxygen environment for the refrigeration chamber. There may be one, two or more refrigeration chambers. When multiple refrigeration chambers are provided, different refrigeration chambers may be high-oxygen chambers or low-oxygen chambers for storing food with different oxygen content requirements.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
