Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigerators, and in particular to a refrigerator with a detachable odor-removing module. BACKGROUND

[0002] With the improvement of people's living standards, the refrigerator has become an indispensable electrical appliance in the family, which is used to store various food materials to prolong the shelf life of the food materials. However, during the long-term use of the refrigerator, a more prominent problem is the internal odor problem. Due to the limited internal storage space of the refrigerator and the complex situation of the stored food materials, a large amount of odor gas is easily generated in the relatively closed space environment. The main sources of these odor gases are two aspects. On the one hand, the food materials themselves have special odors, such as onions and durians, which have strong and unique odors. On the other hand, after the food materials are contaminated by bacteria, they will rot and produce odors such as trimethylamine, methyl mercaptan, and hydrogen sulfide. The existence of odors seriously affects the experience of consumers when using the refrigerator and reduces the overall use comfort of the refrigerator.

[0003] In order to solve the internal odor problem of the refrigerator, a kind of odor-removing module is commonly used in the refrigerator on the market. The odor-removing module is based on ceramic or activated carbon as the substrate, and has a metal catalyst component plated on the surface. This odor-removing module can purify the odor in the refrigerator chamber to some extent, and try to eliminate odor gas through related chemical or physical adsorption, catalysis and other action principles, and create a relatively clean internal environment.

[0004] Although the existing odor-removing module can handle the odor in the refrigerator to some extent, it has obvious shortcomings. After a long time of work, the odor-removing performance of the odor-removing module will decrease, which directly leads to poor odor-removing effect, and the removal ability of odor gas is reduced, and the odor-removing efficiency is also reduced. Especially after a long time of use, the odor-removing performance cannot meet the actual requirements of users for various odors generated in the refrigerator, so that users can still smell unbearable odors at the moment when the refrigerator door is opened, which greatly affects the user experience. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a refrigerator with a detachable odor-removing module to solve the problem that the odor-removing performance of the odor-removing module will decrease after a long time of work, which directly leads to poor odor-removing effect, and the removal ability of odor gas is reduced, and the odor-removing efficiency is also reduced, which greatly affects the user experience.

[0006] The present application provides a refrigerator with a detachable odor-removing module, wherein the refrigerator comprises an odor-removing module, and the odor-removing module is detachably installed on a refrigeration air duct cover plate of the refrigerator.

[0007] The odor removal module comprises a shell and a catalyst assembly, the shell is composed of an upper cover and a lining box;

[0008] The lining box is provided with clamping claws on both sides, the cold storage air duct cover plate is provided with a mounting groove, and the odor removal module is fixed in the mounting groove through the clamping claws on both sides of the lining box.

[0009] In some possible implementation manners, the upper cover is provided with an air inlet, the lining box is provided with an air outlet, the inner side of the upper cover is provided with a buckle, the periphery of the lining box is provided with a buckle hole matched with the buckle on the inner side of the upper cover, and the upper cover and the lining box are fixedly connected through the buckle.

[0010] In some possible implementation manners, the catalyst assembly is detachably installed on the lining box of the shell.

[0011] In some possible implementation manners, the inner surface of the lining box is provided with a limiting groove, the limiting groove forms a limiting structure of the catalyst assembly, and the catalyst assembly is fixed to the inner surface of the lining box through the limiting groove.

[0012] In some possible implementation manners, the catalyst assembly takes ceramic or activated carbon as a base material, and a catalyst on the surface of the base material is selected from one or more of metal oxides such as manganese, copper, titanium, cerium, zinc and silver.

[0013] In some possible implementation manners, the refrigerator further comprises an ozone generator, and the ozone generator is arranged at the air inlet.

[0014] In some possible implementation manners, the air outlet is provided with an odor sensor.

[0015] In some possible implementation manners, the ozone generator and the odor sensor are electrically connected with a controller in the refrigerator.

[0016] As can be seen from the above technical solution, this application provides a refrigerator with a detachable odor-eliminating module. The refrigerator includes an odor-eliminating module, which is detachably installed on the refrigerator's refrigeration air duct cover. The odor-eliminating module includes a shell and a catalyst assembly. The shell consists of a top cover and a liner. The liner has claws on both sides, and the refrigeration air duct cover has an installation groove. The odor-eliminating module is fixed in the installation groove by the claws on both sides of the liner. The detachable design of the odor-eliminating module in the refrigerator allows users to easily remove it from the refrigerator for thorough cleaning. For activated carbon odor-eliminating modules that easily absorb dust, impurities, and odor molecules, their surface and internal pores may become clogged after prolonged use, affecting the odor-eliminating effect. By disassembling, they can be deeply cleaned by rinsing with water and wiping, removing these substances that affect performance and restoring a certain degree of odor-eliminating ability. Different users have different requirements for the odor environment inside the refrigerator. Some users may be more sensitive to odors. With a detachable odor-eliminating module, they can easily choose a more efficient odor-eliminating product to meet their high requirements for the freshness of the air inside the refrigerator, thus enhancing their satisfaction when using the refrigerator. Using a detachable odor-eliminating module in the refrigerator plays a positive and important role in many aspects, including cleaning and maintenance, function adjustment, extending the refrigerator's lifespan, and improving the user experience.

[0023] Embodiments will be described in detail below with reference to examples illustrated in the accompanying drawings. When the following description refers to the drawings, same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following embodiments are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples of systems and methods consistent with some aspects of the present disclosure as detailed in the claims.

[0024] With the improvement of people's living standards, the refrigerator has become an indispensable electrical appliance in the family, which is used to store various food materials to prolong the preservation period of food materials. However, during the long-term use of the refrigerator, a more prominent problem is the internal odor problem. Because the internal storage space of the refrigerator is limited, and the stored food materials are various and complex, a large amount of odor gas is easily generated in the relatively closed space environment. The sources of these odor gases mainly have two aspects, one is the special smell of the food materials themselves, such as onions, durians and other food materials with strong and unique smell; the other is the odor generated by the rotten and deteriorated food materials contaminated by bacteria, such as trimethylamine, methyl mercaptan, hydrogen sulfide and other odor gases. The existence of odor seriously affects the experience of consumers when using the refrigerator, and reduces the overall use comfort of the refrigerator.

[0025] In order to solve the internal odor problem of the refrigerator, a kind of odor removal module is commonly used in the refrigerator on the market at present, which is based on ceramic or activated carbon as the substrate, and has a metal catalyst component plated on the surface. This odor removal module can purify the odor in the refrigerator chamber to a certain extent, and try to eliminate odor gas through related chemical or physical adsorption, catalysis and other action principles, and create a relatively clean internal environment.

[0026] Although the existing odor removal module can handle the odor in the refrigerator to a certain extent, it has obvious shortcomings. After a long time of work, the odor removal performance of the odor removal module will be attenuated, which directly leads to the deterioration of the odor removal effect, the removal ability of the odor gas is reduced, and the odor removal efficiency is also reduced. Especially after long-term use, the odor removal performance cannot meet the actual requirements of users for various odors generated in the refrigerator, so that users will still smell unbearable odor at the moment of opening the refrigerator door, which greatly affects the user experience.

[0027] Therefore, in order to solve the problem that the deodorization performance of the deodorization module will be attenuated after a long time of work, which directly leads to the deterioration of the deodorization effect, the removal ability of the deodorization module for odor gas is reduced, and the deodorization efficiency is also reduced, greatly affecting the user's experience, the refrigerator with a detachable deodorization module is provided, which can be easily taken out from the refrigerator by the user, and the deodorization module is designed to be detachable and replaceable in the refrigerator chamber, so that the user can replace it regularly when the deodorization performance of the deodorization module is attenuated, so as to realize the decomposition of odor in the refrigerator chamber.

[0028] In some embodiments, the refrigerator with a detachable deodorization module provided by the present application comprises a deodorization module, as shown in the accompanying drawings, the deodorization module is detachably installed on the refrigeration air duct cover plate 1 of the refrigerator. Figs. 1 to 3

[0029] The deodorization module comprises a shell 2 and a catalyst assembly 3, and the shell 2 is composed of an upper cover 21 and a lining box 22.

[0030] The lining box 22 is provided with clamping claws 224 on both sides, the refrigeration air duct cover plate 1 is provided with a mounting groove, and the deodorization module is fixed in the mounting groove through the clamping claws on both sides of the lining box 22.

[0031] In some embodiments, the upper cover 21 is provided with an air inlet 211, the lining box 22 is provided with an air outlet 221, the inner side of the upper cover 21 is provided with a buckle 212, the periphery of the lining box 22 is provided with a buckle hole 222 which is in butt joint with the buckle 212 on the inner side of the upper cover 21, and the upper cover 21 and the lining box 22 are fixedly connected through the buckle 212.

[0032] The shape of the clamping claw 224 generally needs to match the inner wall profile of the mounting groove, which is generally designed as a hook-shaped or claw-shaped structure with a certain curvature, angle and length, and the size needs to be accurately matched with the space size of the mounting groove to ensure that it can be smoothly inserted into the mounting groove and stably clamped. For example, the width of the clamping claw 224 is slightly smaller than the width of the entrance of the mounting groove, which facilitates insertion, while the length and thickness of the clamping part can withstand the weight of the deodorization module and external forces such as vibration and pulling that may occur in daily use, preventing it from falling off easily.

[0033] ​The material of the clamping jaw needs to have certain elasticity and rigidity. The elasticity allows the clamping jaw to deform moderately when inserted into the installation slot, so as to smoothly enter the slot. The rigidity ensures that the shape is maintained after clamping, providing reliable fixing force. The shape of the clamping jaw is reasonably designed, for example, the clamping jaw structure with a certain arc and gradually changing thickness, so that it can better fit the slot wall after being inserted into the installation slot, increase the contact area, uniformly disperse the force, and improve the reliability and stability of the fixing. The clamping jaw 224 is made of a material with good elasticity, rigidity, and wear resistance and aging resistance, which can meet the requirements of elastic deformation and maintain structural stability during long-term use. For example, high-quality engineering plastics (such as ABS, PP, etc.) or elastic metals (such as stainless steel, etc.) can produce elastic deformation to some extent, facilitating the insertion and clamping of the clamping jaw, and are not prone to brittle and deformation during long-term use. The elastic metal has higher strength and can withstand greater external force, and can maintain shape stability under frequent use.

[0034] The material of the installation slot needs to be compatible with the material of the clamping jaw. It needs to ensure that the two have a suitable friction coefficient, facilitating the insertion and removal of the clamping jaw, and it should not cause corrosion and wear due to incompatible materials during long-term contact, affecting the fixing effect. For example, if the clamping jaw is made of metal, the inner wall of the installation slot can be treated with a wear-resistant and corrosion-resistant plastic coating, or a hard plastic material that is compatible with the metal can be selected.

[0035] A reinforcing structure, such as a reinforcing rib or a thickened connection part, is provided at the connection part of the clamping jaw 224 and the liner box 22 to prevent the clamping jaw from falling off the liner box during long-term stress. At the same time, limit structures such as clamping grooves and protrusions are reasonably arranged on the inner wall of the installation slot. These structures precisely match the shape of the clamping jaw, not only guiding and positioning during installation, but also limiting the displacement of the clamping jaw during long-term use, further enhancing stability.

[0036] The connection between the clamping jaw 224 and the liner box 22 needs to be firm, which can be achieved by one-piece molding or reliable assembly process, to ensure that the clamping jaw 224 does not fall off the liner box when stressed. For example, the clamping jaw is made by injection molding one-piece, which becomes part of the overall structure of the liner box 22, eliminating weak connection points and ensuring the integrity and reliability of the overall structure.

[0037] The structure of the liner box 22 is designed to evenly distribute the fixing force received by the clamping jaw 224 to the entire liner box 22 and the odor-removing module, avoiding local excessive stress that may damage the components. For example, the liner box 22 near the clamping jaw 224 is provided with a reinforcing rib structure to assist in sharing the external force received by the clamping jaw, so that the odor-removing module can be stably fixed in the installation slot.

[0038] The inner wall of the mounting groove is usually provided with corresponding clamping grooves, protrusions or smooth limiting surfaces, etc., which cooperate with the clamping pawl 224 to achieve precise positioning and stable fixation. For example, the inner wall of the mounting groove is provided with clamping grooves corresponding in shape to the clamping pawl 224, which, after the clamping pawl is inserted, are embedded in the clamping grooves to limit the movement of the clamping pawl in all directions, thereby achieving good limiting effect.

[0039] The mounting groove requires high dimensional accuracy, and its length, width and depth, etc. are accurately designed according to the specifications of the odor-removing module and the clamping pawl 224 to ensure that the clamping pawl 224 can be smoothly inserted and tightly clamped, while a certain tolerance range is reserved to accommodate the possible minor size differences of different batches of products and the size changes caused by factors such as temperature changes in the actual use environment.

[0040] Through the cooperation of the clamping pawl 224 and the mounting groove, when the user installs the odor-removing module, he or she only needs to align the clamping pawl 224 with the entrance of the mounting groove and then gently push it in, and the clamping pawl 224 can be automatically clamped and fixed. The whole process does not require the use of complex tools, and the operation is simple and fast, which can be easily completed by ordinary users, greatly improving the installation efficiency and facilitating the operation when the refrigerator is used for the first time or the odor-removing module is replaced.

[0041] Similarly, when the odor-removing module needs to be disassembled, such as cleaning, maintenance or replacement, only by exerting appropriate external force can the clamping pawl 224 be separated from the clamped state of the mounting groove, and the odor-removing module can be easily taken out. This convenient disassembly method further facilitates the user's daily management of the odor-removing module.

[0042] The clamping between the clamping pawl 224 and the mounting groove can provide stable and reliable fixation effect for the odor-removing module. Even if the refrigerator experiences vibration caused by opening and closing the door, slight shaking during operation of the refrigeration system and other situations during daily use, the odor-removing module will not easily shift or fall off, and can always remain in the correct installation position, thereby ensuring the normal play of its odor-removing function and stably purifying the odor in the interior space of the refrigerator.

[0043] The cooperation of the mounting groove and the clamping pawl 224 also achieves precise positioning of the odor-removing module, so that it is in the best odor-removing working position in the refrigerator, ensuring that the purifying substances released by the odor-removing module or the purifying effect exerted can uniformly cover all areas of the refrigerator, improving the odor-removing effect and efficiency. This fixing method has certain universality and compatibility in design. As long as the specifications of the mounting groove and the clamping pawl 224 match within a certain reasonable range, it can be applied to odor-removing modules of different models and sizes and refrigerators of different styles, facilitating the application in the series production and market promotion of products and reducing the production and adaptation costs.

[0044] Regarding the dimensional tolerance of the clamping pawl 224

[0045] Length tolerance: generally controlled between ±0.1mm to ±0.2mm. If the length of the claw 224 is too long, it may cause difficulty in inserting the installation slot, even damage the installation slot or the claw 224 itself; while too short, it cannot achieve reliable clamping and fixing, and the odor-eliminating module is easy to loosen or fall off.

[0046] Width tolerance: generally between ±0.05mm to ±0.15mm. The claw 224 that is too wide may not be able to smoothly insert into the installation slot, while the claw 224 that is too narrow may have a large gap between the installation slot after clamping, affecting the stability of the fixed.

[0047] Thickness tolerance: relatively high precision requirements, about ±0.05mm to ±0.1mm. Too thick may cause the claw 224 to deform when inserted due to too much interference, affecting its elasticity and clamping effect; too small may not provide enough clamping force.

[0048] When designing the claw 224 and the installation slot, the actual weight, size of the odor-eliminating module and the external force that may be borne during the use of the refrigerator and other factors should be considered to carry out rigorous size calculation and tolerance setting. Ensure that the size precision of the claw and the installation slot is high, such as the tolerance mentioned above is controlled within a reasonable range, to avoid too large size deviation leading to loose fit or difficult installation, and then affecting the long-term stability.

[0049] Considering that the refrigerator may change in different use environments, such as temperature, humidity and other conditions, and through the elastic clamping structure of the claw and the installation slot, it can adapt to the size changes of the components caused by these environmental factors to some extent, still maintain a good fixed state, and will not cause fixed failure due to thermal expansion and contraction and other phenomena, ensuring the long-term stable use of the odor-eliminating module.

[0050] In summary, the odor-eliminating module is fixed in the installation slot through the claws on both sides of the liner box, which has significant technical effects in terms of convenient installation, stable fixation and structural compatibility, and plays an important role in the effective application of the odor-eliminating module of the refrigerator.

[0051] In some embodiments, the inner surface of the liner box 22 is provided with a limiting groove 223, and the limiting groove 223 forms a limiting structure of the catalyst assembly 3. The catalyst assembly 3 is fixed to the inner surface of the liner box 22 through the limiting groove 223.

[0052] In some embodiments, the catalyst assembly 3 is detachably installed on the liner box 22 of the shell 2. The catalyst assembly 3 is made of ceramic or activated carbon as a substrate, and the catalyst on the surface of the substrate is selected from one or more of manganese, copper, titanium, cerium, zinc, silver and other metal oxides.

[0053] In some embodiments, the refrigerator further comprises an ozone generator, which is arranged at the air inlet.

[0054] In some embodiments, an odor sensor is arranged at the air outlet 221.

[0055] In some embodiments, the ozone generator and the odor sensor are electrically connected to a controller in the refrigerator.

[0056] If the refrigerator often stores food materials with strong odor or easy to produce odor (such as durians, onions, etc.), or the food materials are stored in a messy way and are easy to deteriorate and produce more odor gas, the odor intensity and types handled by the odor removal module are large, which will also consume the odor removal capacity faster and reduce the service life. Therefore, the controller needs to obtain the information sent by the odor sensor in real time, and when the information of the odor sensor indicates that the odor in the refrigerator has exceeded the standard seriously, a prompt will be sent to the user to enable the user to adjust the food materials in the refrigerator in time, thereby improving the service life of the odor removal module.

[0057] If the refrigerator is placed in a relatively harsh environment in terms of temperature, humidity, etc., such as a high-temperature and humid environment, which is easy to breed bacteria in the odor removal module and accelerate the aging of the internal materials, thereby affecting the service life, and may shorten the service life of the odor removal module from one or two years to a few months. On the contrary, in a good environment with dryness and suitable temperature, the odor removal module can maintain a good working state for a longer time. Therefore, in some embodiments, the compartment in the refrigerator is also provided with a temperature and humidity sensor, and the controller obtains the temperature and humidity sent by the temperature and humidity sensor in real time, and when the temperature and / or humidity exceeds the threshold value, the refrigeration or heating system is started in time to increase or decrease the temperature or humidity in the compartment, thereby improving the service life of the odor removal module.

[0058] The detachable design enables the user to easily take out the odor removal module from the refrigerator for comprehensive and meticulous cleaning. For example, for activated carbon type odor removal modules that are easy to adsorb dust, impurities and odor molecules, the surface and internal pores thereof may be blocked after a long period of use, affecting the odor removal effect. By detaching, it can be deeply cleaned by flushing with water, wiping, etc. to remove these performance-affecting substances, thereby restoring certain odor removal capacity.

[0059] The detachable structure of the odor purification module allows the user to periodically detach the odor purification module to check whether it is damaged or aged, such as whether there are problems such as loose parts or surface coating peeling. Moreover, when some parts are found to be damaged, targeted replacement can be more convenient, without having to replace the entire module as with a non-detachable odor purification module, which increases the cost of use. Different types of odor purification modules can be flexibly detached and replaced according to different use scenarios and user needs. For example, when there are more seafood and other heavy-smelling food materials, a better odor purification module that is specifically designed to remove fishy smell and other odors can be replaced; when the odor in the refrigerator is relatively light, a relatively basic and energy-saving odor purification module can be selected, so as to better adapt to the actual odor purification needs and improve the odor purification efficiency and targeting.

[0060] As the use time of the refrigerator increases, the performance of the odor purification module will change. The detachable odor purification module can be conveniently detached when its performance decays to a certain extent, and a new module can be replaced, so as to ensure that the refrigerator can always maintain a good odor purification state and avoid long-term suffering from odors in the refrigerator due to the failure of the odor purification module.

[0061] Because the odor purification module can be cleaned and replaced in time, the internal environment of the refrigerator can be kept relatively fresh, reducing the corrosion and invasion of odor gas and bacteria, mold and the like that may accompany odor generation on the inner tank, refrigeration system and other components of the refrigerator, which helps to maintain the good working state of the components in the refrigerator, thereby prolonging the overall service life of the refrigerator to a certain extent.

[0062] The detachable design makes it not too difficult for the user to operate, and the user can complete the detachment, installation and other processes of the odor purification module without professional personnel or complex tools, which is convenient for daily use and management, and makes the user more at ease and comfortable when using the refrigerator. Different users have different requirements for the odor environment in the refrigerator, and some users may be more sensitive to odors. Through the detachable odor purification module, a more efficient odor purification product can be easily selected to meet the high requirements of the user for the freshness of the air in the refrigerator, thereby enhancing the satisfaction of the user when using the refrigerator.

[0063] In summary, the use of the detachable odor purification module in the refrigerator has a positive and important role in cleaning and maintenance, function adjustment, prolonging the service life of the refrigerator and improving the user experience, and the like.

[0064] The application provides a refrigerator with a detachable odor-removing module, which comprises an odor-removing module detachably mounted on a refrigeration air duct cover plate of the refrigerator; the odor-removing module comprises a shell and a catalyst assembly, and the shell is composed of an upper cover and a lining box; the lining box is provided with clamping claws on both sides, the refrigeration air duct cover plate is provided with a mounting groove, and the odor-removing module is fixed in the mounting groove through the clamping claws on both sides of the lining box. The odor-removing module in the refrigerator is designed to be detachable, so that the user can easily take out the odor-removing module from the refrigerator and clean it comprehensively and carefully. For the activated carbon odor-removing module which is easy to adsorb dust, impurities and odor molecules, the surface and internal pores thereof may be blocked after long-term use, affecting the odor-removing effect. By detaching, the odor-removing module can be deeply cleaned by washing with clean water, wiping and the like, so as to remove the performance-affecting substances and restore the odor-removing capacity. Different users have different requirements for the odor environment in the refrigerator, and some users may be more sensitive to odor. By using the detachable odor-removing module, a more efficient odor-removing product can be easily selected to meet the high requirement of the user on the air freshness in the refrigerator, thereby enhancing the satisfaction of using the refrigerator. The use of the detachable odor-removing module in the refrigerator has a positive and important role in cleaning and maintenance, function adjustment, prolonging the service life of the refrigerator and improving the user experience.
