Description

Technical Field

[0001] This utility model relates to the technical field of gas filtration, specifically to a filtration assembly and an electrical appliance or induction cooker having the assembly. Background Technology

[0002] Ceramic cooktops and induction cooktops are two widely used cooking appliances in modern kitchens. Ceramic cooktops use infrared radiation to heat food through a ceramic panel, offering advantages such as compatibility with all cookware, even heating, and the ability to slow-cook at low temperatures. Induction cooktops, on the other hand, use electromagnetic induction to heat the cookware itself, featuring high thermal efficiency, rapid heating, and good safety. Both provide efficient and convenient heating solutions for home cooking.

[0003] However, both ceramic cooktops and induction cooktops focus primarily on heating, generally lacking mechanisms to handle the fumes, steam, and volatile odors produced during cooking. Users still rely on large range hoods to remove these fumes, especially during stir-frying and deep-frying. In open kitchens, small apartments, or simple cooking scenarios, installing and using large range hoods is neither convenient nor economical. Furthermore, when using an induction cooktop only for hot pot, barbecue, or other dining activities at the dining table, while the heat and aromas don't need to be forcefully removed, preliminary filtration and purification can effectively improve the local air quality in the dining area and enhance comfort.

[0004] Therefore, there is a clear need in the existing technology: to add a compact and efficient smoke filtration module to countertop cooking appliances such as ceramic cooktops and induction cooktops, so that they can directly treat the smoke generated at the source of cooking without relying on an external range hood.

[0005] Therefore, it is necessary to design a filter assembly that can be used in such electrical appliances. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0030] See Figures 1-11 A filter assembly includes a main body 1, which has a receiving cavity 101 for installing a filter assembly 345. The upper part of the receiving cavity 101 is open to form an air inlet end. The bottom wall of the receiving cavity 101 has a vent groove 102 forming an air outlet end. The main body 1 has a pressure cap 2 for fixing the filter assembly 345 to the receiving cavity 101.

[0031] The main body 1 provides a stable mounting base for the filter assembly 345. The receiving cavity 101 is used to accommodate the placement of the filter assembly 345. The open air inlet at the top of the receiving cavity 101 allows cooking fumes and external gases from the main body 1 to enter smoothly. The venting groove 102 on the inner bottom wall forms a smooth air outlet channel, ensuring that fumes and external gases from the main body 1 flow through the filter assembly for filtration under the suction of the fan 7. The pressure cap 2 can fix the filter assembly in the receiving cavity 101 to prevent the filter assembly from easily detaching from the main body 1.

[0032] The main body 1 is annular and has a plurality of accommodating cavities 101 arranged circumferentially in the main body 1. A separator 103 is provided between two adjacent accommodating cavities 101.

[0033] The pressure cap 2 is provided with an opening groove 201 at the upper open position of the receiving cavity 101, and the pressure cap 2 is provided with a plug rib 202 for inserting into the receiving cavity 101 and pressing the filter assembly.

[0034] The opening slot 201 of the pressure cap 2 precisely corresponds to the air inlet end of the upper part of the receiving cavity 101, which will not block the entry of flue gas, ensuring smooth air intake and not affecting the filtration efficiency. After the insertion rib 202 is inserted into the receiving cavity 101, the filter component is directly pressed on, which can tightly fix the filter component in the receiving cavity 101.

[0035] The bottom wall of the receiving cavity 101 is provided with a plurality of spaced ventilation grooves 102; The receiving cavity 101 is provided with mounting slots 104 arranged vertically at intervals for installing filter components.

[0036] The several spaced ventilation slots 102 on the bottom wall of the receiving cavity 101 increase the ventilation area at the air outlet, allowing the filtered flue gas to be discharged quickly. The spaced mounting slots 104 at the top and bottom can accurately position the installation position of the filter components, ensuring that the filter components are placed in layers according to the preset levels, and the flue gas passes through each layer of filter components in sequence and evenly, forming a composite filtration effect.

[0037] The filter assembly includes a primary filter material 3, a secondary filter material 4, and an adsorbent filter material 5 arranged sequentially from the air inlet to the air outlet.

[0038] The primary filter material 3, secondary filter material 4, and adsorbent filter material 5 are arranged sequentially from the air inlet to the air outlet, forming a progressive purification system. The primary filter material 3 intercepts large particulate impurities in the flue gas, reducing the load on subsequent filter components; the secondary filter material 4 further refines the filtration, capturing fine particles and some moisture; and the adsorbent filter material 5 effectively adsorbs volatile odors and residual harmful components from food, achieving comprehensive treatment of cooking fumes, water vapor, and odors. The three-layer filter system works synergistically for a more thorough purification effect, significantly improving the local air quality in the cooking area and meeting users' needs for a clean environment.

[0039] The primary filter material 3 includes a pre-filter, filter cotton, electrostatic filter, and metal filter. The secondary filter material 4 is a high-efficiency filter component, which can be HEPA or melt-blown composite material. HEPA (High Efficiency Particulate Air) filter paper can capture 99.97% of 0.3-micron particles and is commonly found in air purifiers. Melt-blown composite material is made of polypropylene (PP) and polyester (PET) through a melt-blowing process, with fiber diameters of 0.5-5 microns, forming a three-dimensional microporous structure. The adsorbent filter material 5 is activated carbon.

[0040] The pressure cap 2 is detachably mounted on the main body 1, and the filter assembly is detachably mounted on the receiving cavity 101. The detachable mounting of the pressure cap 2 on the main body 1 allows the user to easily open the receiving cavity 101 and replace the filter assembly. This detachable installation design allows users to replace only the failed filter assembly without replacing the entire filter assembly, reducing usage and maintenance costs.

[0041] An appliance includes a body on which the aforementioned filter assembly is mounted, the filter assembly being detachably mounted on the appliance head. The detachable mounting of the filter assembly onto the body allows users to easily remove it for maintenance, cleaning, or replacement as needed, without affecting the normal operation of the appliance. This design allows the appliance to combine heating and cooking functions with fume purification, enhancing its practicality and market competitiveness, and providing users with a more convenient and cleaner user experience.

[0042] The appliance is an induction cooker or an electric ceramic cooker.

[0043] An induction cooker includes a cooktop body 6, on which the aforementioned filter assembly is mounted. The filter assembly is detachably installed on the cooktop body 6. This design allows the induction cooker to retain its original heating advantages while adding a flue gas treatment function, solving the problem of flue gas diffusion during cooking. The detachable installation design of the filter assembly facilitates daily maintenance by allowing users to easily disassemble, clean, or replace the filter components.

[0044] The furnace body 6 is provided with a concentrator 8 for supporting the cookware. The concentrator 8 is installed above the main body 1, and there is an air intake gap between the concentrator 8 and the cookware.

[0045] The concentrator hood 8 serves both to support the cookware and to effectively collect the fumes generated during cooking, preventing them from spreading outwards and guiding them to the main body 1 and filter assembly below, thus improving fume collection efficiency. The pre-drilled air gap between the concentrator hood 8 and the cookware ensures airflow, preventing overly tight seals from affecting cooking results, while also ensuring that fumes smoothly enter the filter assembly for purification. This design combines cookware support with fume collection, resulting in a compact structure that doesn't occupy extra space, allowing the induction cooker to handle fume emissions without affecting its core cooking functions.

[0046] The concentrator shroud 8 has a hollow structure. The upper part of the cookware is supported on the upper part of the concentrator shroud 8, and the bottom of the cookware needs to be placed on the microcrystalline plate of the stove body. Therefore, the concentrator shroud 8 needs to be manufactured according to the specific shape of the cookware. Alternatively, the concentrator shroud 8 can be made by splicing together multiple split rings.

[0047] The wind-gathering cover 8 is configured as a whole, or the wind-gathering cover 8 includes several shells 801 spliced ​​into a ring structure. Each shell 801 is provided with a first mounting groove 802 for installing a first magnet. The bottom of each shell 801 is provided with a second mounting groove 803 for installing a second magnet. Two adjacent shells 801 are magnetically fixed to each other by the first magnet. The bottom of the wind-gathering cover 8 is magnetically fixed to the main body 1 by the second magnet.

[0048] The furnace body 6 has an upper air inlet connected to the ventilation groove 102 at the top, and an internal air duct connected to the upper air inlet inside the furnace body 6. The bottom of the furnace body 6 has a fan 7 and an exhaust port 601. The air inlet of the fan 7 is connected to the internal air duct, and the air outlet of the fan 7 is connected to the exhaust port 601.

[0049] The blower 7 can be fixed to the bottom of the furnace body 6 with screws.

[0050] The upper part of the furnace body 6 may be provided with a positioning concave surface, and the bottom of the main body 1 is provided with a positioning post. In this way, when the main body 1 is installed on the furnace body 6, the main body 1 is not easy to shift. The wind concentrator hood 8 can also be installed on the upper part of the main body 1 through this positioning structure.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
