Description

Technical Field

[0001] This invention relates to the field of food preservation technology, and in particular to an electrolysis component and a refrigerator. Background Technology

[0002] As living standards improve, consumers have higher demands for refrigerators, hoping to extend the shelf life of food. Different foods have different oxygen requirements for storage. For fruits and vegetables, oxidation with oxygen damages nutrients, pigments, flavor compounds, and other components, making them unsuitable for storage in oxygen-rich environments. Fresh meat, on the other hand, requires sufficient oxygen to prolong its shelf life.

[0003] Existing controlled atmosphere devices typically consist of a cathode, an anode, and an electrolyte filling the space between them. These devices facilitate the reduction of oxygen at the cathode by allowing contact between the cathode and the surrounding air; the specific reaction is: O₂ + 2H₂O + 4e⁻. － →4OH － Meanwhile, an oxidation reaction occurs at the anode, producing oxygen, with the reaction equation: 4OH⁻. － →O2 + 2H2O + 4e － Generally, controlled atmosphere devices are equipped with an air outlet, which is connected to an oxygen-controlled chamber via a pipe. The oxygen content in the oxygen-controlled chamber is regulated by adding oxygen-controlled gas.

[0004] Under normal use, the electrolyte in the controlled atmosphere device (CAD) of a refrigerator will not leak. However, during transportation, the refrigerator may tip over, and the electrolyte in the CAD may flow from the vent and pipes into the oxygen-controlled compartment. This could allow harmful components in the electrolyte to enter the compartment and contaminate the food, posing a safety hazard. Summary of the Invention

[0037] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The terms used in this embodiment, such as "upper," "above," "lower," and "below," which indicate spatial relative positions, are used for ease of explanation 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 position" may be intended to include different orientations of the device besides those shown in the figures during use or operation. For example, in this embodiment, "upper," "lower," "left," "right," "front," and "rear" all refer to the spatial relative positions of the refrigerator under normal operating conditions.

[0039] The terms "first," "second," "third," "fourth," etc., used in this invention are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Furthermore, it should be noted that, unless otherwise explicitly stated and limited, the term "connection" should be interpreted broadly. For example, a connection can be a direct connection or an indirect connection through an intermediate medium; it can be a fixed connection, a movable connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] It should be noted that in this invention, "oxygen-rich space" refers to a space with a relatively high oxygen concentration, in which users can store oxygen-loving ingredients; "oxygen-deficient space" refers to a space with a relatively low oxygen concentration, in which users can store ingredients that are prone to oxidation.

[0041] To enable those skilled in the art to better understand the technical solutions of this invention, the appendices in the embodiments of this invention will be described below. Figure 1 -12, The technical solutions in the embodiments of the present invention are clearly and completely described.

[0042] An embodiment of the present invention provides a refrigerator (not shown in the figure), including a cabinet and a door pivotally connected to the cabinet. The cabinet may include an outer shell and multiple inner liners. The outer shell is located on the outermost side of the entire refrigerator to protect the entire refrigerator. The multiple inner liners are enclosed by the outer shell, and the space between the inner liners and the outer shell is filled with insulating material (forming a foam layer) to reduce heat loss from the inner liners. Each inner liner may define a forward-opening storage compartment, and the storage compartment may be configured as a refrigerator compartment, a freezer compartment, a variable temperature compartment, etc. The specific number and function of the storage compartments can be configured according to pre-defined needs. The door is movably disposed in front of the inner liners to open and close the storage compartments of the inner liners.

[0043] In some embodiments, the container can also be divided into oxygen-rich and oxygen-deficient spaces, so that different foods can be stored separately to achieve better storage results.

[0044] An embodiment of the present invention provides an electrolysis component, which is disposed inside a box and located outside an oxygen-enriched space. The electrolysis component has the function of producing oxygen and producing hydrogen or consuming oxygen.

[0045] The electrolysis assembly may include an electrolysis box 11 disposed within the refrigerator body, an electrolyte containing chamber 12 and a product gas collecting chamber 13 located within the electrolysis box 11, and an electrode 14 connected within the electrolysis box 11. Further, the electrode 14 includes a cathode plate and an anode plate. The electrolyte containing chamber 12 stores electrolyte, which is connected to the reaction zone of electrode 14. The product gas collecting chamber 13 is also connected to the reaction zone of electrode 14. An oxygen-regulating gas is separated from the electrolyte in the electrolysis containing chamber through an electrochemical reaction. This oxygen-regulating gas enters the product gas collecting chamber 13 and is then transported to an oxygen-rich space and / or an oxygen-deficient space, thereby regulating the oxygen concentration in the oxygen-rich and oxygen-deficient spaces.

[0046] In an optional embodiment, the cathode plate in the electrolysis assembly can also be disposed in an oxygen-deficient space or in a chamber connected to the oxygen-deficient space. The cathode plate is in contact with the air in the oxygen-deficient space, and the cathode plate undergoes an oxidation-reduction reaction with the oxygen in the air, which can consume the oxygen in the oxygen-deficient space to reduce the oxygen concentration in the oxygen-deficient space.

[0047] The oxygen-regulating gas can include oxygen, hydrogen, etc., and the product gas gathering chamber 13 can include an oxygen gathering chamber, a hydrogen gathering chamber, etc. This embodiment only uses the oxygen gathering chamber as an example for specific explanation. The structure of the hydrogen gathering chamber or other gas gathering chambers can be the same as that of the oxygen gathering chamber, and will not be described in detail here.

[0048] In one embodiment, the cathode plate is connected to the negative terminal of an external power source, and the anode plate is connected to the positive terminal of the external power source. When current flows through the electrolyte (usually water), at the anode, hydroxide ions (OH-) in water molecules... － ) loses electrons to form oxygen and hydrogen ions (H+). + At the cathode, hydrogen ions gain electrons to form hydrogen gas. This process can be represented as:

[0049] At the anode, water molecules lose electrons and undergo oxidation to produce oxygen and hydrogen ions: 2H₂O → O₂ + 4H₂O + ;

[0050] At the cathode, hydrogen ions gain electrons and undergo a reduction reaction to produce hydrogen gas: 4H₂O + +4e - →2H2.

[0051] The oxygen produced by the electrolysis unit is introduced into the oxygen-enriched space. If the electrolysis unit produces hydrogen, the hydrogen is introduced into the oxygen-deficient space. If the electrolysis unit consumes oxygen, the oxygen-consuming component is located in the oxygen-deficient space. This allows for the adjustment of the oxygen concentration in the oxygen-enriched and oxygen-deficient spaces, respectively.

[0052] In this embodiment, an oxygen regulating pipe 21 is connected to the electrolysis box 11. The oxygen regulating pipe 21 has an oxygen outlet 211 communicating with the product gas gathering chamber 13 in the electrolysis box 11 and an oxygen inlet 212 communicating with the outside of the electrolysis box 11. The electrolysis assembly also includes a replenishment box 31 disposed on one side of the electrolysis box 11. The replenishment box 31 has a filtration zone 32. The oxygen inlet 212 is connected to the filtration zone 32 of the replenishment box 31. The replenishment box 31 is also provided with a filter outlet 321 located in the filtration zone 32. After being filtered by the filtration zone 32, the electrolyzed oxygen is then transported to the oxygen-enriched space through the filter outlet 321, thereby regulating the oxygen content in the storage space.

[0053] The refrigerator may tip over during transport, causing the electrolysis unit to also tip over. The electrolysis unit has at least one tipping direction. At any tipping angle α in each direction, at least one of the oxygen outlet 211 and oxygen inlet 212 is above the highest liquid level line within the electrolysis box 11. The highest liquid level line within the electrolysis box 11 refers to the level at which liquid can no longer be added.

[0054] A replenishment pipe 41 connects the replenishment box 31 and the electrolysis box 11. The replenishment pipe 41 has an outlet 411 communicating with the inside of the replenishment box 31 and an inlet 412 communicating with the electrolyte container 12 inside the electrolysis box 11. At any tilting angle α in each tilting direction, the outlet 411 or the inlet 412 is higher than the highest liquid level line inside the electrolysis box 11.

[0055] As an example, the tilting direction can include four directions: front, back, left, and right. The tilting angle α ranges from 0° to 90°. When α is 0°, the refrigerator is in a normal, untilted state. When α is 30° or 60°, the refrigerator is tilted in any tilting direction. When α is 90°, the refrigerator is in a horizontal, tilted state.

[0056] With the refrigerator upright, oxygen outlet 211 is connected to the upper edge of the electrolysis box 11, and oxygen inlet 212 and filter outlet 321 are connected to the upper edge of the replenishment box 31. The liquid inlet 412 is not higher than the lumen of the replenishment pipe 41, while the liquid outlet 411 is higher than the liquid inlet 412. Furthermore, the lowest liquid level line of the electrolyte container 12 is not lower than the upper edge of the electrode 14. The lowest liquid level line of the electrolyte container 12 refers to the point at which the electrolysis assembly stops electrochemically reacting with the electrolyte after the liquid level in the electrolysis box 11 reaches this line. A warning structure, such as a liquid level sensor, can be installed inside the electrolysis box 11. When the electrolyte level reaches the lowest liquid level line and the replenishment box 31 stops replenishing liquid to the electrolysis box 11, a warning message can be issued and the electrolysis assembly can be stopped.

[0057] As an example, any tilting state includes a first tilting state in which the refrigerator is rotated 90° to the right, a second tilting state in which the refrigerator is rotated 90° to the left, a third tilting state in which the refrigerator is rotated 90° to the front, and a fourth tilting state in which the refrigerator is rotated 90° to the back.

[0058] In the first tilting state, oxygen outlet 211 and liquid inlet 412 are above the highest liquid level line a.

[0059] In the second pouring state, the oxygen inlet 212 and the liquid outlet 411 are above the highest liquid level line b.

[0060] In the third pouring state, oxygen outlet 211 and liquid outlet 411 are above the highest liquid level line c.

[0061] In the fourth pouring state, oxygen inlet 212 and liquid inlet 412 are above the highest liquid level line d.

[0062] It is easy to understand that during the process of switching the refrigerator from a non-tilted state to any tilted state, the refrigerator tilts gradually. During this tilting process, the oxygen outlet 211 and oxygen inlet 212 may change from both being above the highest liquid level line in the electrolysis box 11 to one of them being above the highest liquid level line in the electrolysis box 11. Similarly, the liquid inlet 412 and liquid outlet 411 may change from both being below the highest liquid level line in the electrolysis box 11 to one of them being above the highest liquid level line in the electrolysis box 11.

[0063] With this design, the electrolyte in the electrolysis box 11 will not leak into the oxygen-controlled compartment used for preservation during the refrigerator's handling and tipping, thus preventing contamination of the food inside. Even if a small amount of electrolyte enters the oxygen-controlled pipe 21 and the replenishment pipe 41 when the refrigerator is tipped over, the electrolyte can still enter the replenishment box 31, further preventing electrolyte leakage.

[0064] In an optional embodiment, the oxygen inlet 212 of the oxygen regulating pipe 21 can be connected to other external filtration structures to achieve oxygen filtration. When the oxygen regulating pipe 21 is connected to other external filtration structures, a small amount of electrolyte entering the oxygen regulating pipe 21 can enter the external filtration structure, which can also prevent the electrolyte from contaminating the oxygen regulating chamber.

[0065] Furthermore, as the electrode 14 undergoes an electrochemical reaction with the electrolyte, the electrolyte level drops, allowing the electrolyte to be replenished into the electrolysis box 11 using the replenishment box 31. Since it is necessary to control the maximum electrolyte level in the electrolyte container 12, a liquid control structure is provided in the electrolysis box 11.

[0066] The liquid replenishment box 31 has a liquid storage area 33 and a liquid control area 34. The liquid control structure defines the liquid replenishment line of the liquid control area 34. The liquid replenishment line of the liquid control area 34 refers to the liquid level after the liquid level is lower than the liquid replenishment line, after which liquid is replenished from the liquid storage area 33 to the liquid control area 34.

[0067] The liquid replenishment box 31 includes a base 311, a liquid storage area 33, and a liquid control area 34, both formed within the base 311. The liquid storage area 33 is formed by a liquid storage area constituting wall 312, and the liquid control area 34 is formed by a liquid control cavity constituting wall 313. The liquid storage area constituting wall 312 and the liquid control cavity constituting wall 313 together define the shape of the base 311. As a preferred manufacturing method, in some embodiments, the liquid storage area constituting wall 312 and the liquid control cavity constituting wall 313 are integrally formed, thereby preventing leakage and other defects in the base 311.

[0068] The hydraulic control structure includes an isolation plate 35 and a hydraulic control pipe 36. The isolation plate 35 separates the liquid storage area 33 and the liquid control area 34, and has an inlet hole 351 connecting the liquid storage area 33 and the liquid control area 34. The first end of the hydraulic control pipe 36 extends into the liquid control area 34, and the second end of the hydraulic control pipe 36 extends into the outside of the liquid control area 34. The first end of the hydraulic control pipe 36 is the liquid replenishment line.

[0069] Referring to this specific embodiment, when both the storage area 33 and the control area 34 contain solutions (such as electrolytes) and the liquid level in the control area 34 is flush with the first end of the control tube 36 (i.e., the lower end of the control tube 36 in the figure), the first end of the control tube 36 will be sealed by the solution in the control area 34, thereby forming a gas cavity 37 on the lower side of the isolation plate 35. The solution in the storage area 33 cannot flow into the control area 34 through the inlet hole 351. When the solution in the control area 34 decreases, the liquid level in the control area 34 drops, the gas cavity 37 on the lower side of the isolation plate 35 increases, the liquid seal at the first end of the control tube 36 is released, and the solution in the storage area 33 can flow into the control area 34 through the inlet hole 351. The gas cavity 37 on the lower side of the isolation plate 35 decreases until the first end of the control tube 36 is flush with the liquid level in the control area 34, at which point a liquid seal is formed again.

[0070] It should be noted that, according to the dimensions of the replenishment box 31, the replenishment box 31 has a first part and a second part that are interconnected. The width of the first part is greater than the width of the second part, so that a groove is formed on one side of the second part. At least in the horizontal direction, the portion of the electrolysis box 11 located in the product gas collection chamber 13 is embedded in the groove. This makes the structure of the electrolysis assembly more compact and saves the required installation space. Furthermore, the portion of the electrolysis box 11 located in the electrolyte receiving chamber 12 is on the horizontal side of the liquid control zone 34. Under the action of the replenishment pipe 41, when the liquid level in the electrolyte receiving chamber 12 drops, the solution (e.g., water) in the liquid control zone 34 is automatically replenished into the electrolyte receiving chamber 12.

[0071] Based on the above description, it can be understood that when the automatic replenishment module replenishes the electrolyte box 11 through the liquid control zone 34, the liquid storage zone 33 can replenish the solution in the liquid control zone 34 in a timely and rapid manner, so that the solution in the liquid control zone 34 has a relatively stable liquid level, thereby ensuring that the replenishment process of the automatic replenishment module to the electrolyte box 11 is stable and reliable.

[0072] The first end of the liquid control pipe 36 (i.e., the replenishment line) is not lower than the highest edge of the electrode 14. When the liquid level in the electrolysis assembly is about to fall below the highest edge of the electrode 14, the liquid in the liquid control zone 34 will replenish the electrolyte receiving cavity 12, ensuring that the electrode 14 is always in contact with the electrolyte. Furthermore, the first end of the liquid control pipe 36 (i.e., the replenishment line) is not higher than the highest liquid level line in the electrolysis box 11. In this way, the height of the highest liquid level line in the electrolysis box 11 can be controlled, so that the electrolyte in the electrolysis box 11 will not leak in large quantities when the refrigerator is tilted in any direction.

[0073] The replenishment box 31 has a top cover 314 located at the top, and the lower surface of the top cover 314 is recessed upward to form an air cavity 37, the upper end of the liquid control tube 36 extending into the air cavity 37. It is easy to see that the air cavity 37 is located above the liquid storage area 33.

[0074] The replenishment box 31 of the present invention is also provided with a replenishment port 315. Specifically, in this embodiment, the replenishment port 315 is provided on the top cover 314 and is used to connect the liquid storage area 33 and the outside of the replenishment box 31. The user can add solution (such as electrolyte) to the automatic replenishment module through the replenishment port 315. As a preferred embodiment of the present invention, the cross-sectional area of ​​the liquid control area 34 in the horizontal direction is smaller than the cross-sectional area of ​​the liquid storage area 33 in the horizontal direction. In this specific embodiment, the liquid control cavity forming wall 313 is connected to the bottom of the liquid storage area forming wall 312. The projection of the liquid control cavity forming wall 313 on the plane where the bottom of the liquid storage area forming wall 312 is located can only cover a local area of ​​the bottom of the liquid storage area forming wall 312. Since the liquid control area 34 is formed in the liquid control cavity forming wall 313 and the liquid storage area 33 is formed in the liquid storage area forming wall 312, the cross-sectional area of ​​the liquid control area 34 in the horizontal direction is smaller than the cross-sectional area of ​​the liquid storage area 33 in the horizontal direction. Based on this implementation structure, when the solution in the storage zone 33 enters the control zone 34 to maintain the stability of the solution level in the control zone 34, the solution in the storage zone 33 has a slower rate of liquid level drop, so the user does not need to frequently add liquid to the storage zone 33.

[0075] In some preferred embodiments of the present invention, the replenishment box 31 further has a filtration zone 32 for filtering gas, the filtration zone 32 being in communication with the liquid storage zone 33, such that the solution in the liquid storage zone 33 can flow into the filtration zone 32.

[0076] The automatic liquid replenishment module has a water level limiting mechanism that limits the minimum water level in the filtration zone 32. In addition, the top cover 314 of the liquid replenishment box 31 has an air collection chamber 38 and an air inlet channel 39 at a position corresponding to the filtration zone 32. The upper end of the air outlet channel is connected to the air filter outlet 321, and the lower end of the air outlet channel is lower than the liquid level of the minimum water level in the filtration zone 32. The oxygen inlet 212 of the oxygen regulating pipe 21 is connected to the upper part of the air collection chamber 38.

[0077] Based on the configuration of the filtration zone 32 of this invention, the automatic liquid replenishment module involved in this invention can not only realize the automatic liquid replenishment function, but also perform gas filtration function. Specifically, the gas to be filtered enters the gas collecting chamber 38 from the oxygen inlet 212. As more and more gas accumulates in the gas collecting chamber 38, it will enter below the liquid surface of the filtration zone 32 under pressure, and then be discharged through the gas outlet channel, and then transported to the oxygen conditioning chamber through the gas filter outlet 321, thereby completing the filtration.

[0078] Understandably, since the filtration zone 32 is connected to the storage zone 33, the solution (e.g., electrolyte) in the storage zone 33 can directly enter the filtration zone 32 as a filtration medium. When the solution in the storage zone 33 is consumed, the water level limiting mechanism ensures that the filtration zone 32 has a minimum water level. At the same time, since the lower end of the air outlet channel is lower than the liquid level of the minimum water level in the filtration zone 32, the gas entering the filtration zone 32 through the air inlet channel 39 will inevitably clean the solution in the filtration zone 32. This ensures that the filtration zone 32 will not fail to filter due to excessive consumption of the solution in the storage zone 33.

[0079] The gas generated by the electrolysis unit and discharged through its housing exhaust port can enter the filter zone 32 through the air intake channel 39. After being washed by water in the filter zone 32, the gas can be transported to the high oxygen space of the refrigerator to increase the oxygen concentration inside.

[0080] Furthermore, in the embodiment shown, the water level limiting mechanism is a baffle 316 disposed at the connection position between the liquid storage area 33 and the filtration area 32. The baffle 316 extends upward from the bottom wall of the liquid replenishment box 31, and the liquid storage area 33 and the filtration area 32 are connected at the upper side of the baffle 316.

[0081] In other words, a connecting port is formed on the upper side of the baffle 316, through which the liquid storage area 33 and the filtration area 32 are connected. The solution in the liquid storage area 33 can enter the filtration area 32 through the connecting port, and the upper edge of the baffle 316 limits the minimum water level of the filtration area 32. When the solution in the liquid storage area 33 is consumed, the liquid level in the filtration area 32 will not be lower than the upper edge of the baffle 316.

[0082] Further preferably, with reference to the illustration, in some specific embodiments, the top cover 314 has a cavity wall 317 defining a gas collecting chamber 38, the lower edge of which is below the plane of the lowest water level in the filtration zone 32. This design causes the solution in the filtration zone 32 to form a liquid seal on the lower end of the gas collecting chamber 38, thereby ensuring that all gas collected in the gas collecting chamber 38 can be filtered.

[0083] Furthermore, in a preferred embodiment, the lower end of the air intake channel 39 is located inside the cavity wall 317 of the air collection chamber 38, and the lower end is positioned higher than the lower edge of the cavity wall 317. This ensures that the gas entering the filter zone 32 for water washing via the air intake channel 39 is collected to the maximum extent by the air collection chamber 38.

[0084] In a further preferred embodiment, in order to minimize the risk of gas entering the filter zone 32 for water washing via the air intake channel 39 entering the liquid storage zone 33, the air intake channel 39 is located on the side of the gas collection chamber 38 away from the baffle 316.

[0085] In some other embodiments of the present invention, the plane of the bottom wall of the filtration zone 32 is lower than the plane of the bottom wall of the liquid storage zone 33. As shown in the figure, the bottom wall of the liquid storage zone 33 is the first bottom wall, and the bottom wall of the filtration zone 32 is the second bottom wall. Since the second bottom wall is lower than the first bottom wall, it can be ensured that there is enough solution inside the filtration zone 32 to participate in the water washing action, thereby ensuring the water washing effect.

[0086] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
