Technical field

The present application relates to the technical field of kitchen appliances, specifically to an integrated stove.

Background technique

In related technologies, in order to simplify the product structure, filters are often installed in the exhaust duct in the cabinet. However, when the filter needs to be cleaned or replaced, the user needs to remove the drawer on the cabinet and disassemble the exhaust duct. Due to the cleaning and replacement operations, the integrated stove has technical problems such as difficulty in disassembly and assembly of filters and complicated user maintenance operations.

Therefore, how to design an integrated stove that can overcome the above technical defects has become an urgent technical problem to be solved.

Application content

This application aims to solve at least one of the technical problems existing in the prior art.

To this end, one aspect of the present application proposes an integrated stove.

In view of this, the present application provides an integrated stove. The integrated stove includes: a heating component used to support and heat the container, including an air duct; a hood component connected to the heating component and communicated with the air duct for passing through The air duct extracts oil fume; the positioning component is located in the hood assembly; the filter element is detachably connected to the positioning component and can pass through the air duct for filtering the oil fume.

This application proposes an internal circulation integrated stove, which can centrally extract the oil fume generated by cooking into the interior of the integrated stove, complete grease filtration and odor filtration inside the integrated stove, and then discharge it back to the user. In order to realize the internal circulation of oil fume in the indoor environment where the household is located, there is no need to set up a complex external exhaust structure.

Integrated stoves include heating components and fan components. The heating component is the main structure of the integrated stove and is used to position and support other structures on the integrated stove. The top of the heating component can provide a cooking operation surface for the user, and a container for holding ingredients is placed above the heating component to support and heat the container through the heating component. Thus, finished food that meets the user's needs can be cooked on the heating component.

An air duct is formed inside the heating component. The first end of the air duct is connected to the space above the heating component. During the process of cooking food, oil smoke is concentrated above the heating component. The air duct allows the oil smoke above the heating component to flow into the integrated stove. . The fan assembly is a suction power structure of the integrated stove. The fan assembly is connected to the heating assembly, and a cavity is formed in the fan assembly. The second end of the air duct is connected to the cavity. The fan assembly can extract oil fume above the heating assembly through the cavity and air duct. For example, after the fan is turned on, the fan assembly draws the gas in the air duct into the fan through the cavity to form a negative pressure environment in the air duct area. Under the action of this negative pressure environment, the oil smoke above the heating component is pressed in. into the air duct to complete the extraction of oil fumes and prevent the oil fumes from spreading to the indoor environment.

The integrated stove also includes a filter element, which is used to filter the oil fume drawn into the interior of the integrated stove to filter out impurities contained in the oil fume and substances that emit odors. This is to ensure that the gas eventually discharged back into the room will not pollute the indoor environment.

In related technologies, in order to simplify the product structure, filters are often installed in the exhaust duct in the cabinet. However, when the filter needs to be cleaned or replaced, the user needs to remove the drawer on the cabinet and disassemble the exhaust duct to complete the cleaning. and replacement operations, so that the integrated stove has technical problems such as difficulty in disassembling and assembling filters and complicated user maintenance operations. At the same time, because the sizes of filter elements produced by different manufacturers are inconsistent, the sizes of the corresponding exhaust pipes are different, making it impossible to form a unified smoke exhaust pipe standard for different brands and different models of products. As a result, users can only purchase smoke exhaust pipes of corresponding brands and models when installing or replacing smoke exhaust pipes. As a result, the cost of maintaining smoke exhaust pipes for users increases, which is not conducive to product promotion.

In this regard, this application provides a positioning assembly. The positioning assembly is installed in the fan assembly. The filter element is detachably connected to the positioning assembly. The filter element is arranged on the upwind side of the wind wheel inside the fan assembly, that is, the filter element is located between the air duct and the wind wheel. During the period, the oil fume entering the cavity from the air duct must first pass through the filter and then be inhaled into the wind wheel. By arranging the filter in the cavity, the restriction of the filter on the size of the smoke exhaust pipe can be lifted, so that the fan can be connected to smoke exhaust pipes of different models and manufacturers, thereby reducing user maintenance of the integrated stove. cost, and is conducive to the formation of unified smoke exhaust pipe standards among different brands. At the same time, arranging the filter element in the cavity can rationally utilize the lateral space in the cavity to complete the built-in filter element without increasing the thickness of the integrated stove. It can be seen that by arranging the filter element in the cavity, the technical problems of high maintenance cost and poor product promotion of integrated stoves existing in related technologies are solved. It has achieved the technical effect of optimizing the structural layout of the integrated stove, improving the practicality of the integrated stove, and improving the user experience.

At the same time, arranging the filter on the upwind side of the fan can prevent impurities contained in oil smoke from being sucked into the fan, thereby reducing the rate at which the fan is contaminated by impurities and extending the maintenance cycle and service life of the fan. This will further improve the working stability of the integrated stove and reduce the technical effect of the failure rate of the integrated stove.

Wherein, the filter element disposed in the cavity is detachably connected to the positioning assembly, and the size of the filter element is smaller than the size of the air duct, so that the filter element can pass through the air duct. By providing a detachable filter element, the user can remove the filter element from the positioning assembly when cleaning or replacing the filter element, and then install the cleaned filter element or a new filter element to quickly complete the filter element replacement. maintain. On this basis, by limiting the filter element to pass through the air duct, the user can complete the disassembly and assembly of the filter element through the air duct. For example, first remove the grille at the top of the air duct, then extend your hand from the air duct into the cavity, complete the removal of the filter element through the operation, and then take out the filter element from the air duct. In the same way, the installation process is opposite to the disassembly process and will not be described again here.

It can be seen that the integrated stove defined by this technical solution can complete the maintenance of the filter directly above the stove, eliminating the complicated operations of dismantling drawers on cabinets and disassembling smoke exhaust ducts. In order to achieve the technical effect of optimizing the structural layout of the integrated stove, reducing the difficulty of filter maintenance, and improving the user experience.

In addition, the above-mentioned integrated stove provided by this application may also have the following additional technical features:

Exemplarily, the positioning component includes a frame, the frame is annular, and the filter element is embedded inside the annular frame to position the filter element in the radial direction of the annular frame to prevent the filter element from being dislocated or coming out. The positioning assembly also includes a first grid plate. The first grid plate is connected to the first port on the frame and covers the first port. The first grid plate can block the filter element on the basis of ensuring that the airflow passes through the positioning assembly. Specifically, the first grid plate faces the leeward side, and the second port of the frame faces the upwind side, thereby preventing the filter member from being pushed out of the frame by the airflow through the first grid plate. On this basis, the peripheral side of the frame is set opposite to the air duct. This arrangement can block impurities falling in the air duct through the peripheral side of the frame, preventing impurities from being directly transferred into the filter element and clogging the filter element, thereby improving the reliability of the filter element. properties and extend the service life of the filter.

During the installation of the filter element, push the filter element into the frame through the second port on the frame until the filter element abuts the first grid plate to complete the installation. On the contrary, when it is necessary to disassemble the filter element, the filter element can be removed from the frame by grabbing the filter element and pulling the filter element out of the second port, and then the filter element can be taken out through the air duct. It can be seen that the structure proposed in this technical solution can protect the filter element on the basis of effectively positioning the filter element. At the same time, the structure has the advantages of low structural complexity and low processing difficulty, which is beneficial to reducing the cost of the positioning component.

In any of the above technical solutions, an escape opening is provided on the peripheral side of the frame facing the air duct, and the escape opening is connected with the second open end of the frame. The positioning assembly also includes: a cover plate, connected with the frame, and covering the escape opening.

In this technical solution, an escape opening is provided on the peripheral side of the frame facing the air duct, and the escape opening is connected with the second opening end on the frame. After completing the installation of the filter element, part of the filter element is exposed in the escape opening. By arranging an escape opening on the frame, the user can remove the filter element from the frame by pushing the filter element exposed in the escape opening, thereby providing a force area for the user, thereby reducing the difficulty of disassembly of the filter element.

On this basis, the positioning assembly also includes a cover plate, which is openably and closably arranged at the escape opening. When the cover is in a closed state, the cover closes the escape port to prevent pollutants dripping from the air duct from directly contacting the filter in the escape port. When the cover is open, the filter in the mouth is prevented from being exposed, and the user can directly touch and operate the filter. Specifically, during the disassembly process, open the cover first, and then disassemble the filter. By providing a cover plate, the probability of the filter element being contaminated by contaminants can be reduced while reducing the difficulty of disassembling the filter element, thereby extending the service life of the filter element.

In any of the above technical solutions, the cover plate is hinged with the frame.

In this technical solution, in order to cooperate with the cover plate, a pair of hinge parts are provided on the frame. The cover plate is flat and has a pair of rotating shaft parts on one side. The rotating shaft part cooperates with the hinge part to enable the cover plate to rotate around the rotating axis. part to rotate. Thereby switching the open state and closed state of the cover through the rotation action. The hinged structure has the advantages of low structural complexity and strong reliability, and can reduce the production cost and failure rate of positioning components while meeting the needs of cover switches. At the same time, compared with the technical solution of setting up a split cover, hinged cover on the frame can prevent the cover from being moved deep into the cavity, thus providing convenience for users to disassemble and install filters.

In any of the above technical solutions, the positioning component further includes: convex ribs, which are provided on the cover plate. When the cover plate covers the escape opening, the convex ribs block the filter element at the second open end.

In this technical solution, the positioning assembly also includes convex ribs, which are arranged on the covering surface of the cover plate. When the cover plate is in a closed state, the convex ribs are located at the second open end of the frame, and the filter element is located between the convex ribs and the cover plate. between the first grid plates, so that the filter element is blocked at the second open end by the raised ribs. By setting convex ribs on the cover plate, the cover plate can lock the filter element with the help of the convex ribs to prevent the filter element from being dislocated or even falling out of the frame due to vibration and other factors during operation. This further improves the reliability and stability of positioning of filter elements by the positioning component and reduces the technical effect of filter failure rate.

In any of the above technical solutions, the escape opening is used for the filter element to pass through, and the positioning assembly also includes: a second grid connected to the frame, located at the second open end of the frame, used to block the filter element.

In this technical solution, the size of the filter element is smaller than the size of the escape opening, so that the filter element can be loaded into the frame through the escape opening. On this basis, the positioning assembly further includes a second grid plate. The second grid plate is installed on the second open end of the frame and covers the second port. The second grid plate can block the air flow through the positioning assembly on the basis of ensuring that the air flow passes through the positioning assembly. Filters. Under this structure, the filter element completes the disassembly and assembly action in the longitudinal direction, which is different from the transverse disassembly and assembly in the aforementioned technical solution. When installing the filter element, insert the filter element into the escape opening from top to bottom. On the contrary, when disassembling the filter element, pull the filter element out of the frame through the escape opening. After the assembly of the filter element is completed, the frame, the first grid plate and the second grid plate cooperate to position the filter element to ensure that the filter element can be parked at a predetermined working position. This upper and lower disassembly and assembly structure allows users to directly perform disassembly and assembly operations through the air duct, and facilitates users to observe whether the filter element is installed in place. That is, this disassembly and assembly structure can further reduce the difficulty of disassembly and assembly of the filter element and optimize the positioning component structure. The technical effect of providing convenient conditions to users.

In any of the above technical solutions, the first grid separates the cavity into a first cavity and a second cavity; One cavity communicates with the passage and the second cavity, and the second open end of the frame faces away from the second cavity.

In this technical solution, the positioning assembly is disposed transversely in the cavity, and the first grid plate on the positioning assembly divides the cavity into a first cavity and a second cavity. Among them, the top of the first cavity is connected to the air duct, and the frame and the filter element are both arranged in the first cavity. The oil fume flows into the filter element from the air duct and the first cavity, and passes through the first grid after being filtered by the filter element. into the second cavity. Finally, under the action of the internal power structure of the fan assembly, the fan assembly is discharged from the air outlet on the casing.

In any of the above technical solutions, the hood assembly further includes: a fan located in the second cavity.

In this technical solution, the hood assembly includes a fan, which is disposed in the second cavity. The fan can extract oil smoke above the heating component through the cavity and the air duct. For example, after the fan is turned on, the fan draws the gas in the air duct into the fan through the cavity to form a negative pressure environment in the air duct area. Under the action of this negative pressure environment, the oil smoke above the heating component is forced into In the air duct to complete the extraction of oil fumes and prevent the oil fumes from spreading to the indoor environment.

Wherein, the fan is a centrifugal fan, the air inlet end of the fan is located in the second cavity and is connected with the cavity, and the air outlet end of the fan is formed on the outer casing to discharge the oil fume to the outside of the outer casing. The centrifugal fan can pressurize and accelerate the oil fume that is sucked into the interior. On the one hand, the oil fume can be quickly discharged into the exhaust pipe connected to the shell. On the other hand, it helps to improve the suction effect of the oil fume, thereby making the fan It can meet the smoking needs of a large amount of oil fume. At the same time, the centrifugal fan has the characteristics of exhausting air at the upper and lower ends and exhausting at the circumferential side. The horizontal centrifugal fan can make reasonable use of the lateral space in the cavity. Compared with other fan types such as axial flow fans, choosing a centrifugal fan is conducive to compression. The thickness of the shell is used to reduce the space occupied by the integrated stove in the stove.

In any of the above technical solutions, the hood assembly is located below the heating assembly; the second cavity is located on the peripheral side of the first cavity.

In this technical solution, the positional relationship between the heating component and the fan component is explained. Exemplarily, the housing is disposed below the heating assembly. During the installation of the integrated stove, the heating component is embedded into the reserved installation hole on the stove, so that the upper surface of the heating component is used as the work surface. The shell below the heating component is covered by the heating component to hide it inside the stove. When it is necessary to clean and maintain the structure below the heating component, just open the stove door to carry out cleaning and maintenance operations.

The air duct in the heating component extends in the height direction of the integrated stove. By setting up the longitudinally extending air duct, on the one hand, it helps to reduce the air inlet resistance of the air duct and facilitates the introduction of oil smoke into the cavity below. On the other hand, setting up longitudinally extending air ducts can reduce the amount of space occupied by the air ducts inside the heating component, thus providing better space for the layout. It provides convenient conditions for locating the internal working structure of the heating component and is conducive to compressing the thickness of the heating component. In order to achieve the technical effect of optimizing the structural layout of the integrated stove.

On this basis, the first cavity is located directly below the air duct, and the second cavity is located around the first cavity. Arranging the first cavity directly below the air duct can provide convenient conditions for users to disassemble and install the filter. Arranging the second cavity around the first cavity can rationally utilize the lateral space in the shell to expand the size of the oil fume channel without increasing the thickness of the fan assembly, thereby reducing the oil fume suction resistance, thereby improving the integrated stove The fume smoking effect.

In any of the above technical solutions, there are multiple filter elements, and the multiple filter elements are arranged side by side in the length direction of the frame.

In this technical solution, there are multiple filter elements, and the multiple filter elements are arranged side by side in the length direction of the frame. During the installation of filter elements, multiple filter elements are placed in sequence until the internal space of the frame is filled with multiple filter elements. On the contrary, when disassembling the filter elements, first remove the filter elements in the middle of the frame, and then remove the filter elements at both ends of the frame. By arranging multiple filter elements, on the basis of ensuring that the filter element can pass through the air duct, the total length of the filter structure can be increased by splicing multiple filter elements, thereby increasing the air intake of the integrated stove by increasing the area of the filter surface. area, thus improving the ability of the integrated stove to smoke fumes.

Among them, a partition is also provided in the positioning assembly for transversely disassembling the filter. The partition is connected to the inner annular surface of the frame and extends longitudinally to divide the internal space of the frame into multiple sub-chambers arranged side by side. During the installation process, multiple filter elements are installed into multiple sub-chambers one by one. By setting up partitions, the positioning accuracy of multiple filter elements can be improved and gaps between the multiple filter elements can be avoided for oil smoke to pass through. This further improves the effectiveness of the filter element in filtrating oil fumes, thereby improving the practicality of the integrated stove.

In any of the above technical solutions, the integrated stove also includes: a separation component, located in the air duct, used to separate the grease in the oil smoke.

In this technical solution, the integrated stove is also provided with a separation piece, and the separation piece is arranged in the air duct. During the working process, the oil fume flowing into the air duct first flows into the separator, and the separator separates the grease in the oil fume from the air to prevent the grease from continuing to flow into the hood along with the air. By arranging the separation piece, the grease in the oil fume can be prevented from adhering to the internal working structure of the integrated stove, thereby preventing the grease from clogging the air ducts and filters on the one hand, and preventing the grease being sucked into the fan from damaging the fan on the other hand. On the other hand, it eliminates the need to frequently clean the grease inside the integrated stove. This solves the technical problem of the fan being easily damaged by oil dirt and inhaling oil dirt increasing the burden of cleaning the interior of the integrated stove.

In any of the above technical solutions, the separation component includes: a bracket, including an air inlet and an air outlet; a filter screen, located in the bracket, used to separate grease in oil smoke; wherein, the filter screen is arranged opposite to the air inlet, And the filter is recessed away from the air inlet.

This application proposes a separation component that is used in range fume extraction equipment to separate the oil and gas from the fumes drawn into the equipment, so as to reduce the oil content in the fume finally discharged from the range fume extraction equipment. On the one hand, this reduces the environmental pollution caused by the discharged oil smoke. On the other hand, it prevents a large amount of grease from accumulating inside the equipment, reducing the probability that grease will damage the internal electrical structure of the equipment and even cause a fire. On the other hand, it can extend the internal cleaning cycle of the range hood equipment.

Exemplarily, the separation assembly includes a bracket and a filter. The function of the bracket is to fix the filter. An air inlet and an air outlet are formed on the bracket. Oil fumes carrying grease particles flow into the interior of the bracket from the air inlet. After being separated by the filter, the gaseous oil smoke is discharged from the air outlet to the outside of the bracket. . When the oil fume passes through the separation component, the grease particles contained in the oil fume will be adhered to the micropores of the filter and remain on the filter to achieve the effect of separating grease and air.

The material of the filter screen is a material that can form multiple micropores, that is, the filter screen can capture grease and allow air to pass through. Commonly used materials are multi-layered metal flat mesh, metal wire mesh, etc. Non-metal material mesh can also be used. and other materials.

In related technologies, the grease filter assembly in the range hood equipment has a low grease filtration efficiency for the inhaled oil fume. On the one hand, the oil fume still contains more grease when it is discharged from the outside of the smoke pipe, which will cause damage to the surrounding air and the use environment. Pollution affects the user experience of the product. On the other hand, the grease that is not filtered out by the grease filter assembly will adhere to the internal structure of the range hood equipment. A large amount of accumulated grease will cause short circuits, leakage and even burning of internal electrical components, resulting in the safety and reliability of the range hood equipment. Technical problems such as poor performance and high failure rate. In addition, the rapid accumulation of grease inside the range hood equipment will shorten the cleaning cycle of the equipment, causing users to frequently clean the oil inside the range hood equipment, ruining the user experience.

In this regard, the filter screen proposed in this application is arranged opposite to the air inlet, and the filter screen is recessed in a direction away from the air inlet. By arranging a filter that is recessed toward the inside of the air inlet, it helps to increase the contact area between the oil fume and the filter. By increasing the probability of the oil in the oil fume colliding with the filter, the probability of the filter catching the oil is increased, thereby improving the separation component. Separation effect on grease.

It can be seen that by setting up a concave filter, the grease content in the oil fume passing through the filter can be reduced. On the one hand, this reduces the oil content contained in the final discharged airflow and weakens the airflow's ability to pollute the indoor environment. On the other hand, it can reduce the accumulation speed of oil dirt inside the range hood equipment, thereby reducing the possibility of short circuit, leakage or fire in the electrical components inside the equipment due to oil corrosion, and at the same time prolongs the internal cleaning cycle of the range hood equipment and reduces the frequency of user cleaning. This solves the technical problems existing in related technologies: serious pollution of the environment by the exhaust air flow, poor safety and reliability, high failure rate, high cleaning frequency, and poor user experience. In order to achieve the technical effect of optimizing the structure of the separation component, improving the grease separation performance of the separation component, improving the safety and reliability of range hood equipment, and providing convenient conditions for users.

In addition, the above-mentioned separation component provided by this application may also have the following additional technical features:

In the above technical solution, the filter screen is cut through a plane perpendicular to the length direction of the bracket, and on the resulting cross section, the filter screen is symmetrically distributed.

In this technical solution, the shape of the filter element is limited. For example, the filter screen is cut through a plane perpendicular to the length direction of the bracket. On the obtained cross section, the left and right ends of the filter screen are close to the air inlet, the middle part is recessed away from the air inlet, and the filter screen is symmetrically distributed on Both sides of the midline of the bracket. By setting up symmetrically distributed filters, the flow field characteristics of the internal space of the separation component can be optimized, thereby reducing the resistance produced by the filter to the oil fume, thereby increasing the air volume in the separation component, thereby improving the ability of the range hood equipment to extract oil fume. At the same time, symmetrically distributed filters can also reduce the possibility of turbulence or vortex around the filter, thereby reducing aerodynamic noise and improving user experience. In order to achieve the technical effect of optimizing the shape of the filter, reducing the wind resistance of the filter, increasing the separation air volume, and enhancing the fume extraction performance of the range hood equipment.

In any of the above technical solutions, in cross-section, the filter screen includes: a first section extending in a straight direction; a second section symmetrical with the first section and extending in a straight direction; a third section with one end Connect the first section and the other end to the second section.

In this technical solution, the previous technical solution is taken over and the shape of the filter is described in detail. For example, on the obtained cross section, a first section, a second section and a third section are divided on the filter screen according to the shape. The first section and the second section are located on the left and right sides of the third section, and both the first section and the second section extend in a straight direction, with one end close to the air inlet, and the end far away from the air inlet and The third section is connected. By arranging the first section and the second section extending in a linear direction on the left and right areas of the filter, the matching degree between the filter and the flow direction of the oil fume can be further improved to increase the contact area between the oil fume and the filter, and improve the filter's protection against grease particles. capture ability. In this way, the shape of the filter screen can be optimized, the oil pollution separation effect of the separation component can be improved, and the extraction efficiency can be improved. Technical effects on safety and reliability of oil fume equipment.

In any of the above technical solutions, the range of the angle between the first section and the second section is: greater than or equal to 30° and less than or equal to 100°.

In this technical solution, following the aforementioned technical solution, the positional relationship between the first section and the second section is limited. For example, the angle between the first section and the second section that are symmetrically arranged and extend along a straight direction needs to be greater than or equal to 30° and less than or equal to 100°. By limiting the angle a between the first section and the second section to between 30° and 100°, it helps to improve the filter's ability to capture grease particles, thereby improving the oil separation effect of the separation component and improving the correlation Product safety and reliability.

In any of the above technical solutions, the filter screen has an arc shape in cross section.

In this technical solution, a filter screen of the second shape is proposed. For example, in the obtained cross section, the filter screen has an overall arc shape. The surface on the filter that contacts the oil fume is a smooth transition surface. Therefore, by setting a filter with an arc-shaped cross section, the friction between the oil fume and the filter can be reduced while increasing the contact area between the oil fume and the filter. This reduces the aerodynamic resistance of the separation component and increases the air volume circulating inside the separation component. In order to achieve the technical effect of optimizing the shape of the filter and improving the ability of related equipment to extract smoke.

In any of the above technical solutions, the filter screen is V-shaped in cross section.

In this technical solution, a third shape filter is proposed. For example, in the obtained cross-section, the filter screen is V-shaped as a whole. Among them, the filter with a V-shaped cross-section has a better effect on exporting the separated grease. The oil particles attached to the filter can quickly collect to the bottom of the filter under the slope of the V-shaped filter, and finally pass through the bottom of the filter. The end is dripping. It can be seen that by setting up a filter with a V-shaped cross-section, the grease export efficiency can be accelerated on the basis of increasing the contact area between oil smoke and the filter, and avoiding a large amount of grease accumulated on the filter from affecting the permeability of the filter. In order to achieve the technical effect of optimizing the shape of the filter, improving the practicality and reliability of the filter, and enhancing the grease separation performance of the separation component.

In any of the above technical solutions, the bracket includes: a box body, the air inlet is located on the top of the box body; a groove is provided on the box body, and part of the filter screen is provided in the groove and fits with the groove. On the shaped filter.

In this technical solution, the structure of the bracket is explained. Exemplarily, the bracket includes a box body, which is the main support structure on the bracket and is used to position and support other structures such as filters. The opening on the top of the box forms an air inlet on the bracket, and the oil fume passes through the filter from the top of the box downwards. By providing a box with an open top, the separation component can be installed in a longitudinally flowing air duct, so that the separation component can be arranged in the main body of the range hood extraction device.

On this basis, a groove is provided in the box, the opening of the groove faces the air inlet, and the shape of the groove is also concave in the direction away from the air inlet, and its shape is the same as the pre-designed cross-sectional shape of the filter. During the process of assembling the separation assembly, the filter screen is installed in the groove, and the lower surface of the filter screen inserted into the groove can be closely attached to the inner wall of the groove, thereby shaping the filter screen through the groove. Specifically, the filter can be bonded to the groove with glue to prevent the filter from deforming due to external factors such as vibration. It can be seen that by setting grooves, the filter can be maintained in an effective separation shape for a long time, thereby improving the stability of the filter in separating grease. This will achieve the technical effect of optimizing the filter positioning structure and improving the reliability of grease separation in the separation component.

In any of the above technical solutions, the box body includes a slot, and the end of the filter screen adjacent to the air outlet is inserted into the slot.

In this technical solution, a second filter positioning structure is proposed. For example, the box body is provided with a slot, the opening of the slot is opposite to the opening of the groove, and the slot is close to the edge of the air inlet. During the assembly process, insert the left and right ends of the filter into the slots, and snap the middle section of the filter into the groove, thereby limiting the filter to a predetermined shape through the slots and grooves to prevent the filter from breaking. deformation to ensure the effectiveness of the filter in separating grease.

Wherein, when a slot is provided, the box itself can complete the shaping of the filter screen, eliminating the need for a cover structure in other embodiments. Therefore, this positioning method helps to reduce the structural complexity of the stent, thereby reducing the processing difficulty of the stent and reducing the production cost of the stent.

In any of the above technical solutions, the bracket further includes: a cover body, which covers the air inlet and includes a through hole; a pressing part, which is provided at the bottom of the cover body and is pressed on the surface of the filter screen away from the groove, Match the grooves to position the filter.

In this technical solution, a third filter positioning structure is proposed. Exemplarily, the bracket further includes a cover body and a pressing part. The pressing part is installed on the buckling surface of the cover body, and the lower surface of the pressing part is the same as the predetermined separation shape of the filter screen. After the cover is closed on the air inlet area at the top of the box, a gap is left between the pressing part and the groove part, and the filter is tightly pressed in this gap, thereby passing through the lower surface of the pressing part and the inner wall of the groove Co-shaped filter. Under this structure, the pressing part and the groove work together to shape the filter up and down, and the shaping effect is better, which can ensure that the filter remains in the designed predetermined separation shape. At the same time, this structure makes it easier to disassemble and assemble the filter. When the filter needs to be disassembled, the filter can be taken out by opening the cover. During the installation of the filter, seat the filter into the groove and fasten the cover to complete the assembly. This can improve the positioning accuracy of the filter and reduce the difficulty of disassembly and assembly of the filter. Improve the reliability of oil separation and improve the technical effect of users.

Wherein, a through hole is provided on the cover, and the through hole is opposite to the air inlet on the top of the box body to ensure that the oil fume can pass through the through hole and flow into the air inlet.

In any of the above technical solutions, the separation component further includes: a cross beam, which is provided in the through hole.

In this technical solution, the separation component also includes a cross beam. The cross beam is arranged in the through hole. Specifically, multiple cross beams can be arranged side by side in the length direction of the through hole. By setting up cross beams, large-sized objects can be blocked to prevent large-sized objects falling from the air duct from clogging the internal space of the separation component. This in turn reduces the failure rate of separate components.

At the same time, the cross beam can also provide users with a point of strength during the process of disassembling and assembling the cover. Specifically, during the process of disassembling and assembling the cover, the user can pull the cover out of the box by holding the cross beam. The cover can also be moved by holding the crossbar. This reduces the difficulty of disassembly and assembly of the cover and provides convenience for users.

In any of the above technical solutions, the separation component further includes: screws that penetrate the box body and are connected to the pressing portion, and the screws are recessed in the box body; and the cover body is snap-connected with the box body.

In this technical solution, the cover body and the box body are tightly connected by screws. For example, screw holes are provided on the peripheral side of the box body. The pressing part is provided with studs on the surface facing the box body. During the assembly process, align the studs with the screw holes, and then pass the screws through the screw holes and screw into the studs to complete the connection between the cover body and the box body. The connection structure has the advantage of being detachable and can provide convenience for users to clean or replace the filter.

After the assembly of the screws is completed, the screws are recessed into the box body, and the specific recessed depth c ranges from greater than 0 mm to less than or equal to 1 mm. By sinking the screws into the box body, the metal screws exposed outside the box can be prevented from scratching the user, and the screws can also be prevented from scratching the internal structure of the range hood equipment during the process of disassembling and assembling separate components. This will achieve the technical effect of improving the safety and reliability of separation components.

On this basis, one of the cover body and the box body is provided with a card slot, and the other is provided with a buckle. During the installation of the cover body, first snap the buckle into the card slot to complete the cover body and the box body. The box body is initially set, and then the cover and box body are tightened with screws. By providing this snap-in structure, the user can be saved from manually aligning the screw holes and studs, thereby reducing the difficulty of installing the cover. At the same time, the snap-in structure has the advantages of low structural complexity and easy operation, and can improve the user operating experience while reducing the cost of separate components.

In any of the above technical solutions, the air outlet is located on the peripheral side of the box body; the box body also includes an oil storage tank, which is located under the filter screen for collecting grease.

In this technical solution, the air outlet is provided on the peripheral side of the box body, and an oil storage tank is provided on the bottom of the box body. Opening the air outlet on the side of the bracket can prevent the separated grease from flowing out of the air outlet directly under the action of gravity. When more grease adheres to the filter, the grease will flow along the surface of the filter to the lower end of the filter and drip into the oil storage tank, so the grease can be stored in the separation component. Before the oil storage tank is filled with grease, the user can dump or clean the grease inside the oil storage tank by disassembling the separation component so that the separation component can be recycled. Specifically, a liquid level sensor can be installed on the oil storage tank to detect the liquid level of the grease. Thus, the alarm device connected to the liquid level sensor prompts the user to clean the oil storage tank in time. By setting up an oil storage tank, the separation component has the ability to collect and store grease, thereby reducing the possibility of grease contaminating the room and damaging the internal electrical components of the range hood equipment, thereby extending the cleaning and maintenance cycle of the separation component. In order to achieve the technical effect of optimizing the structure of the separated components, reducing the difficulty of maintaining the separated components and improving the user experience.

In any of the above technical solutions, the separation assembly further includes: a protruding portion, which is provided in the oil storage tank and extends in the length direction of the box body.

In this technical solution, the separation component is also provided with a protruding portion. The protruding portion is arranged in the oil storage tank and extends in the length direction of the box body. By providing the protruding portion, the structural strength of the box body can be strengthened to prevent the box body from deforming during operation and preventing the box body from warping and deforming. This can achieve the technical effect of improving the stability of the bracket and extending the service life of the separation components.

For example, part of the bottom wall of the box body is bent upward to form an upward protrusion in the liquid reservoir. This structure can directly form the protrusion through a stamping process, which helps to reduce the complexity of the process of the box body. and reduce box production costs. At the same time, the space formed by the upward convexity can cooperate with the positioning ribs on the range hood equipment to accurately position the separation components, thereby improving the practicality of the separation components.

In any of the above technical solutions, the separation assembly also includes: guide ribs, which are provided on the peripheral side of the bracket. The guide ribs extend in the height direction of the bracket and are used to guide the bracket to be inserted into the integrated stove; the guide ribs include guide ribs. The range of the angle between the inclined surface, the guide inclined surface and the plane in the height direction of the bracket is: greater than or equal to 5° and less than or equal to 35°.

In this technical solution, the separation component is also provided with guide ribs. The guide ribs are arranged on the peripheral side of the bracket. And the guide ribs extend in the height direction of the bracket. The guide piece cooperates with the positioning structure on the integrated stove to guide the separation component to a predetermined installation position, thereby improving the installation accuracy and positioning accuracy of the separation component. For example, a guide bevel is provided on the guide rib, and the angle b between the guide bevel and the plane in the height direction of the bracket is greater than or equal to 5° and less than or equal to 35°. This angle limit can ensure the reliability and effectiveness of the guide, so that The separate components can automatically slide into the air duct.

At the same time, the guide ribs can also enhance the structural strength of the bracket to reduce the possibility of warping and deformation of the bracket, thereby improving the structural stability of the bracket.

Detailed ways

In order to understand the above-mentioned objects, features and advantages of the present application more clearly, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, as long as there is no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

Many specific details are set forth in the following description to fully understand the present application. However, the present application can also be implemented in other ways different from those described here. Therefore, the protection scope of the present application is not limited by the specific disclosures below. Limitations of Examples.

Integrated stoves according to some embodiments of the present application are described below with reference to FIGS. 1 to 37 .

As shown in Figures 1, 2, 3, 7, 35, 36 and 37, one embodiment of the present application proposes an integrated stove 100. The integrated stove 100 includes: a heating component 110 for supporting The support and heating container include an air duct 112; a hood assembly 120, which is connected to the heating assembly 110 and communicates with the air duct 112, and is used to extract oil smoke through the air duct 112; a positioning assembly 130, which is located in the hood assembly 120; filtering The component 140 is detachably connected to the positioning assembly 130 and can pass through the air duct 112 for filtering oil smoke.

This application proposes an internal circulation integrated stove 100. The integrated stove 100 can centrally extract the oil fume generated by cooking into the interior of the integrated stove 100, and complete grease filtration and odor filtration inside the integrated stove 100 before returning it to the user. In order to realize the internal circulation of oil fumes in the indoor environment, it is unnecessary to set up a complex external exhaust structure.

The integrated stove 100 includes a heating component 110 and a fan 126 component. The heating assembly 110 is the main structure of the integrated stove 100 and is used to position and support other structures on the integrated stove 100 . The top of the heating component 110 can provide a cooking work surface for the user, and a container for holding ingredients is placed above the heating component 110 to support and heat the container through the heating component 110 . Thus, finished food that meets the user's needs can be cooked on the heating component 110 .

An air duct 112 is formed inside the heating assembly 110. The first end of the air duct 112 is connected to the space above the heating assembly 110. During the process of cooking food, oil smoke is concentrated above the heating assembly 110. The air duct 112 is connected to the space above the heating assembly 110. The channel 112 allows the oil fume above the heating component 110 to flow into the integrated stove 100 . The fan 126 assembly is the suction power structure of the integrated stove 100. The fan 126 assembly is connected to the heating assembly 110, and a cavity 124 is formed in the fan 126 assembly. The second end of the air duct 112 is connected to the cavity 124. The fan 126 assembly can extract oil fumes above the heating assembly 110 through the cavity 124 and the air duct 112 . For example, after the fan 126 is turned on, the fan 126 assembly draws the gas in the air duct 112 into the fan 126 through the cavity 124 to form a negative pressure environment in the air duct 112 area. Under the action of this negative pressure environment, heating The oil fume above the component 110 is pressed into the air duct 112 to complete the suction of the oil fume and prevent the oil fume from spreading to the indoor environment.

The integrated stove 100 also includes a filter 140 , which is used to filter the oil fume drawn into the interior of the integrated stove 100 to filter out impurities and odor-emitting substances contained in the oil fume. This is to ensure that the gas eventually discharged back into the room will not pollute the indoor environment.

In related technologies, in order to simplify the product structure, filters are often installed in the exhaust duct in the cabinet. However, when the filter needs to be cleaned or replaced, the user needs to remove the drawer on the cabinet and disassemble the exhaust duct to complete the cleaning. and replacement operations, so that the integrated stove has technical problems such as difficulty in disassembling and assembling filters and complicated user maintenance operations. At the same time, because the sizes of filter elements produced by different manufacturers are inconsistent, the sizes of the corresponding exhaust pipes are different, making it impossible to form a unified smoke exhaust pipe standard for different brands and different models of products. As a result, users can only purchase smoke exhaust pipes of corresponding brands and models when installing or replacing smoke exhaust pipes. As a result, the cost of maintaining smoke exhaust pipes for users increases, which is not conducive to product promotion.

In this regard, this application provides a positioning assembly 130. The positioning assembly 130 is installed in the fan 126 assembly. The filter 140 is detachably connected to the positioning assembly 130, and the filter 140 is arranged on the upwind side of the wind wheel inside the fan 126 assembly, that is, filtering The filter element 140 is located between the air duct 112 and the wind wheel. The oil fume entering the cavity 124 from the air duct 112 must first pass through the filter element 140 and then be inhaled into the wind wheel. By arranging the filter 140 in the cavity 124, the restriction of the filter 140 on the size of the smoke exhaust pipe can be released, so that the fan 126 can be connected to different models and smoke exhaust pipes produced by different manufacturers, thereby reducing the user's cost of maintaining the integrated stove 100. , and is conducive to the formation of unified smoke exhaust pipe standards among different brands. At the same time, arranging the filter element 140 in the cavity 124 can reasonably utilize the lateral space in the cavity 124 to complete the built-in filter element 140 without increasing the thickness of the integrated stove 100. It can be seen that by arranging the filter element 140 in the cavity 124, the technical problems of high maintenance cost and poor product promotion of integrated stoves existing in related technologies are solved. The structural layout of the integrated stove 100 has been optimized and the practicality of the integrated stove 100 has been improved. Technical effects that improve user experience.

At the same time, arranging the filter 140 on the upwind side of the fan 126 can prevent impurities contained in the oil fume from being sucked into the fan 126, thereby reducing the rate at which the fan 126 is contaminated by impurities and extending the maintenance cycle and service life of the fan 126. Thereby improving the working stability of the integrated stove 100 and reducing the technical effect of the failure rate of the integrated stove 100.

The filter 140 disposed in the cavity 124 is detachably connected to the positioning assembly 130 , and the size of the filter 140 is smaller than the size of the air duct 112 so that the filter 140 can pass through the air duct 112 . By providing the detachable filter element 140, the user can remove the filter element 140 from the positioning assembly 130 when the filter element 140 needs to be cleaned or replaced, and then install the cleaned filter element 140 or a new filter element 140. To quickly complete the maintenance of the filter element 140 . On this basis, by restricting the filter element 140 to pass through the air duct 112 , the user can complete the disassembly and assembly of the filter element 140 through the air duct 112 . For example, first remove the grill at the top of the air duct 112, and then extend your hand from the air duct 112 into the cavity 124. After completing the removal of the filter element 140, the filter element 140 is taken out of the air duct 112. In the same way, the installation process is opposite to the disassembly process and will not be described again here.

It can be seen that the integrated stove 100 defined in this embodiment can complete the maintenance of the filter 140 directly above the stove, eliminating the complicated operations of disassembling drawers on cabinets and disassembling smoke exhaust ducts. In this way, the structural layout of the integrated stove 100 can be optimized, the maintenance difficulty of the filter 140 can be reduced, and the technical effect of improving the user experience can be achieved.

As shown in Figures 2 and 7, the hood assembly 120 includes: a shell 122, which is connected to the heating component 110 and includes a cavity 124; the air duct 112 is connected to the cavity 124, and the positioning component 130 is located in the cavity 124 and positioned The assembly 130 is arranged opposite to the air duct 112 . The arrow direction in FIG. 7 is the disassembly direction of the filter element 140 .

In this embodiment, the structure of the hood assembly 120 is explained. Illustratively, hood assembly 120 includes housing 122 . The shell 122 is a frame 131 structure of the fan 126 assembly. The shell 122 is connected to the heating component 110 , and a cavity 124 is formed in the shell 122 . The second end of the air duct 112 is connected to the cavity 124 . On this basis, the positioning component 130 disposed in the cavity 124 is connected to the housing 122 , and the positioning component 130 is disposed opposite to the air duct 112 , that is, the positioning component 130 is aligned with the air inlet on the housing 122 . By arranging the positioning component 130 relative to the air duct 112, the user can touch the positioning component 130 by extending his hand through the air duct 112, thereby reducing the user's difficulty in disassembling and installing the filter 140, thereby reducing the amount of dust collected. Chengzao 100 maintenance difficulty improves the technical effect of user experience.

As shown in Figures 4, 5, 6, 7 and 8, in one embodiment of the present application, the positioning assembly 130 includes: a frame 131, connected to the housing 122, the frame 131 is annular, and the filter 140 is located on In the frame 131, the peripheral side of the frame 131 is arranged opposite to the air duct 112; the first grid 132 is connected to the frame 131 and is located at the first open end of the frame 131 for blocking the filter 140. The arrow direction in FIG. 6 is the installation direction of the filter element 140 .

In this embodiment, the structure of the positioning component 130 is explained. Exemplarily, the positioning assembly 130 includes a frame 131 , the frame 131 is annular, and the filter element 140 is embedded inside the annular frame 131 to position the filter element 140 in the radial direction of the annular frame 131 to avoid the filter element 140 Dislocation or prolapse. The positioning assembly 130 also includes a first grid 132. The first grid 132 is connected to the first port on the frame 131 and covers the first port. The first grid 132 can ensure airflow through the positioning assembly 130. Block filter 140. Specifically, the first grid 132 faces the leeward side, and the second port of the frame 131 faces the upwind side, thereby preventing the filter 140 from being pushed out of the frame 131 by the airflow through the first grid 132 . On this basis, the peripheral side of the frame 131 is arranged opposite to the air duct 112. This arrangement can block impurities falling in the air duct 112 through the peripheral side of the frame 131, preventing impurities from being directly transferred into the filter element 140 and clogging the filter element 140. , thereby improving the reliability of the filter element 140 and extending the service life of the filter element 140.

During the installation of the filter element 140, the filter element 140 is pushed into the frame 131 through the second port on the frame 131 until the filter element 140 abuts the first grid plate 132 to complete the installation. On the contrary, when the filter element 140 needs to be disassembled, the filter element 140 can be removed from the frame 131 by grabbing the filter element 140 and pulling the filter element 140 out of the second port, and then the filter element can be taken out through the air duct 112 140. It can be seen that the structure proposed in this embodiment can protect the filter element 140 on the basis of effectively positioning the filter element 140 . At the same time, the structure has the advantages of low structural complexity and low processing difficulty, which is beneficial to reducing the cost of the positioning assembly 130 .

As shown in Figures 10, 11, 12 and 14, in one embodiment of the present application, the frame 131 is provided with an escape opening 133 on the peripheral side facing the air duct 112. The escape opening 133 is connected to the second open end of the frame 131. Connected to each other, the positioning assembly 130 also includes: a cover plate 134 connected with the frame 131 and covering the escape opening 133 . The arrow direction in FIG. 14 is the disassembly direction of the filter element 140 .

After completing the installation of filter element 140, part of The filter element 140 is exposed in the escape opening 133 . By arranging the escape opening 133 on the frame 131, the user can remove the filter element 140 from the frame 131 by pushing the filter element 140 exposed in the escape opening 133, thereby providing the user with a force area, thereby reducing the difficulty of disassembly of the filter element 140. .

On this basis, the positioning assembly 130 further includes a cover plate 134 which is openably and closably disposed at the escape opening 133 . When the cover 134 is in a closed state, the cover 134 covers the escape opening 133 to prevent pollutants dripping from the air duct 112 from directly contacting the filter 140 in the escape opening 133 . When the cover 134 is in the open state, the filter element 140 in the escape opening 133 is exposed, and the user can directly touch and operate the filter element 140 . Specifically, during the disassembly process, the cover 134 is opened first, and then the filter element 140 is disassembled. By providing the cover plate 134, the probability of the filter element 140 being contaminated by contaminants can be reduced on the basis of reducing the difficulty of disassembly of the filter element 140, thereby extending the service life of the filter element 140.

The cover plate 134 is flat and has a pair of rotating shaft parts on one side. The rotating shaft parts cooperate with the hinge parts to make the cover plate 134 can rotate around the rotating shaft. Thereby, the open state and the closed state of the cover 134 are switched through the rotation action. The hinged structure has the advantages of low structural complexity and strong reliability, and can reduce the production cost and failure rate of the positioning assembly 130 on the basis of meeting the switching requirements of the cover 134 . At the same time, compared with the embodiment provided with a split cover 134, hingedly connecting the cover 134 to the frame 131 can prevent the cover 134 from being moved deep into the cavity 124, thus providing convenient conditions for the user to disassemble and install the filter 140. .

When the cover plate 134 is in a closed state, the convex rib 135 is located at the second open end of the frame 131, And the filter element 140 is located between the raised ribs 135 and the first grid plate 132 , so that the filter element 140 is blocked at the second open end by the raised ribs 135 . By providing the convex ribs 135 on the cover plate 134, the cover plate 134 can lock the filter element 140 with the help of the convex ribs 135 to prevent the filter element 140 from being dislocated or even falling out of the frame 131 due to vibration and other factors during operation. This further improves the positioning reliability and stability of the filter element 140 by the positioning assembly 130 and reduces the technical effect of reducing the failure rate of the filter element 140 .

As shown in Figures 15, 16 and 17, in one embodiment of the present application, the escape opening 133 is used for the filter element 140 to pass through. The positioning assembly 130 also includes: a second grid 136 connected to the frame 131 and located at The second open end of the frame 131 is used to block the filter element 140 . Among them, the direction of the arrow drawn from the cover plate 134 in Figure 16 is the opening movement direction of the cover plate, and the direction of the arrow drawn from the filter element 140 is the direction of disassembly of the filter element 140. The arrow direction in FIG. 17 is the disassembly direction of the filter element 140 .

That is, this disassembly and assembly structure can further reduce the difficulty of disassembly and assembly of the filter element 140 and achieve optimal positioning of the assembly. 130 structure, providing technical effects with convenient conditions for users.

As shown in Figures 8, 9, 14 and 17, in one embodiment of the present application, the first grid 132 separates the cavity 124 into a first cavity 1242 and a second cavity 1244; the first cavity 1242 communicates with the air passage 112 and the second cavity 1244, and the second open end of the frame 131 faces away from the second cavity 1244. Among them, the direction of the arrow in Figure 9 is the flow direction of the oil fume.

In this embodiment, the positioning assembly 130 is disposed horizontally in the cavity 124, and the first grid 132 thereon divides the cavity 124 into a first cavity 1242 and a second cavity 1244. Among them, the top of the first cavity 1242 is connected to the air channel 112. The frame 131 and the filter element 140 are both arranged in the first cavity 1242. The oil fume flows into the filter element 140 from the air channel 112 and the first cavity 1242. After passing through the filter element 140 After filtering, it passes through the first grid plate 132 and flows into the second cavity 1244. Finally, the fan 126 assembly is discharged from the air outlet on the housing 122 under the action of the internal power structure of the fan 126 assembly.

As shown in FIGS. 17 and 18 , in one embodiment of the present application, the hood assembly 120 further includes: a fan 126 disposed in the second cavity 1244 . Among them, the direction of the arrow in Figure 18 is the oil fume in the hood unit. direction of flow on piece 120.

In this embodiment, the hood assembly 120 includes a fan 126 , which is disposed in the second cavity 1244 . The fan 126 can extract oil smoke above the heating assembly 110 through the cavity 124 and the air duct 112 . For example, after the fan 126 is turned on, the fan 126 draws the gas in the air duct 112 into the fan 126 through the cavity 124 to form a negative pressure environment in the area of the air duct 112. Under the action of this negative pressure environment, the heating assembly The oil fume above 110 is pressed into the air duct 112 to complete the suction of the oil fume and prevent the oil fume from spreading to the indoor environment.

Among them, the fan 126 is a centrifugal fan 126. The air inlet end of the fan 126 is located in the second cavity 1244 and is connected with the cavity 124. The air outlet end of the fan 126 is formed on the shell 122 to discharge the oil fume to the outside of the shell 122. . The centrifugal fan 126 can pressurize and accelerate the oil fume sucked into the interior. On the one hand, the oil fume can be quickly discharged into the exhaust pipe connected to the housing 122. On the other hand, it helps to improve the suction effect of the oil fume, thereby This allows the fan 126 to meet the demand for smoking a large amount of oil fume. At the same time, the centrifugal fan 126 has the characteristics of exhausting air at the upper and lower ends and exhausting at the circumferential side. The horizontal centrifugal fan 126 can reasonably utilize the lateral space in the cavity 124. Compared with the axial flow fan 126 and other types of fan 126, choosing The centrifugal fan 126 is conducive to compressing the thickness of the shell 122 to reduce the space occupied by the integrated range 100 within the range.

In any of the above embodiments, the hood assembly 120 is located below the heating assembly 110; the second cavity 1244 is located around the first cavity 1242.

In this embodiment, the positional relationship between the heating component 110 and the fan 126 component is explained. Illustratively, housing 122 is disposed below heating assembly 110 . During the installation of the integrated stove 100, the heating component 110 is embedded into the reserved installation opening on the stove, so that the upper surface of the heating component 110 is used as a work surface, and the shell below the heating component 110 is blocked by the heating component 110 to hide it. Inside the stove, when the structure below the heating component 110 needs to be cleaned and maintained, the door of the stove can be opened to perform cleaning and maintenance operations.

The air duct 112 in the heating assembly 110 extends in the height direction of the integrated stove 100. By providing the longitudinally extending air duct 112, on the one hand, it helps to reduce the air inlet resistance of the air duct 112 and facilitates the introduction of oil smoke into the lower cavity 124. . On the other hand, providing the longitudinally extending air duct 112 can reduce the space occupied by the air duct 112 inside the heating component 110 , thereby providing convenient conditions for arranging the internal working structure of the heating component 110 and conducive to compressing the thickness of the heating component 110 . Thus, the structural layout of the integrated stove 100 can be optimized. technical effects.

On this basis, the first cavity 1242 is located directly below the air duct 112, and the second cavity 1244 is located around the first cavity 1242. Arranging the first cavity 1242 directly below the air duct 112 can disassemble and install the filter for the user. Part 140 provides convenience. Arranging the second cavity 1244 around the first cavity 1242 can rationally utilize the lateral space in the housing 122 to expand the size of the oil fume channel without increasing the thickness of the fan 126 component, so as to reduce the oil smoke suction resistance. Thereby, the oil fume extraction effect of the integrated stove 100 is improved.

As shown in FIGS. 6 and 16 , in one embodiment of the present application, there are multiple filter elements 140 , and the multiple filter elements 140 are arranged side by side in the length direction of the frame 131 .

In this embodiment, there are multiple filter elements 140 , and the multiple filter elements 140 are arranged side by side in the length direction of the frame 131 . During the installation of the filter element 140 , multiple filter elements 140 are placed in sequence until the internal space of the frame 131 is filled with the multiple filter elements 140 . On the contrary, in the process of disassembling the filter element 140, the filter element 140 in the middle of the frame 131 is first disassembled, and then the filter elements 140 at both ends of the frame 131 are disassembled. By arranging multiple filter elements 140, on the basis of ensuring that the filter elements 140 can pass through the air duct 112, the total length of the filter structure can be increased by splicing multiple filter elements 140, thereby increasing the area of the filter surface to increase integration. The air inlet area of the stove 100 is increased, thereby improving the ability of the integrated stove 100 to extract oil fume.

Among them, a partition is also provided in the positioning assembly 130 for laterally disassembling the filter element 140. The partition is connected to the inner annular surface of the frame 131 and extends longitudinally to divide the internal space of the frame 131 into multiple sub-sections arranged side by side. Chamber. During the installation process, multiple filter elements 140 are installed into multiple sub-chambers one by one. By providing partitions, the positioning accuracy of the plurality of filter elements 140 can be improved and gaps between the plurality of filter elements 140 can be avoided for oil smoke to pass through. This further improves the effectiveness of the filter element 140 in filtering oil fumes, thereby improving the practicality of the integrated stove 100.

As shown in Figures 2 and 19, in one embodiment of the present application, the integrated stove 100 further includes: a separation component 150, which is provided in the air duct 112 and is used to separate grease from oil smoke. The arrow direction in FIG. 19 is the flow direction of oil fume on the separation component 150 .

In this embodiment, the integrated stove 100 is also provided with a separation piece, and the separation piece is disposed in the air duct 112 . During the working process, the oil fume flowing into the air duct 112 first flows into the separator, and the separator separates the grease in the oil fume from the air to prevent the grease from continuing to flow into the hood along with the air. By arranging the separation member, the grease in the oil fume can be prevented from adhering to the internal working structure of the integrated stove 100, thus preventing the grease from clogging the air duct 112 and the filter 140 on the one hand, and preventing it from being sucked into the fan 126 on the other hand. Grease in the blower 126 can be damaged. On the other hand, the need for frequent cleaning of the internal grease of the integrated stove 100 is eliminated. This solves the technical problem of the fan 126 being easily damaged by oil dirt and inhaling oil dirt increasing the internal cleaning burden of the integrated stove 100 .

As shown in Figures 20, 21, 32 and 33, the first embodiment of the present application provides a separation assembly 150. The separation assembly 150 includes: a bracket 152, including an air inlet 1524 and an air outlet 1522; a filter screen 154, located in the bracket 152, is used to separate the grease in the oil fume; wherein, the filter screen 154 is arranged opposite to the air inlet 1524, and the filter screen 154 is recessed in a direction away from the air inlet 1524.

This application proposes a separation component 150. The separation component 150 is used in range hood equipment to separate the oil and gas from the oil fume drawn into the equipment, so as to reduce the oil content in the oil fume finally discharged from the range hood equipment. On the one hand, this reduces the environmental pollution caused by the discharged oil smoke. On the other hand, it prevents a large amount of grease from accumulating inside the equipment, reducing the probability that grease will damage the internal electrical structure of the equipment and even cause a fire. On the other hand, it can extend the internal cleaning cycle of the range hood equipment.

Illustratively, the separation assembly 150 includes a bracket 152 and a filter 154 . The function of the bracket 152 is to fix the filter 154. An air inlet 1524 and an air outlet 1522 are formed on the bracket 152. Oil fumes carrying grease particles flow into the interior of the bracket 152 from the air inlet 1524. After being separated by the filter 154, the gaseous The oil fume is discharged from the air outlet 1522 to the outside of the bracket 152 . When the oil fume passes through the separation component 150, the grease particles contained in the oil fume will be adhered to the micropores of the filter screen 154, and then remain on the filter screen 154, achieving the effect of separating grease and air.

The material of the filter 154 is a material that can form multiple micropores, that is, the filter 154 can capture grease and allow air to pass through. Commonly used materials are multi-layered metal flat mesh, metal mesh, etc., and non-metallic materials can also be used. Material network and other materials.

In related technologies, the grease filter assembly in the range hood equipment has a low grease filtration efficiency for the inhaled oil fume. On the one hand, the oil fume still contains more grease when it is discharged from the outside of the smoke pipe, which will cause damage to the surrounding air and the use environment. Pollution affects the user experience of the product. On the other hand, the grease that is not filtered out by the grease filter assembly will adhere to the internal structure of the range hood equipment. A large amount of accumulated grease will cause short circuits, leakage and even burning of internal electrical components, resulting in the safety and reliability of the range hood equipment. Technical problems such as poor performance and high failure rate. In addition, the rapid accumulation of grease inside the range hood equipment will shorten the cleaning cycle of the equipment, causing users to frequently clean the oil inside the range hood equipment, ruining the user experience.

In this regard, the filter 154 proposed in this application is arranged opposite to the air inlet 1524, and the filter 154 is recessed in a direction away from the air inlet 1524. By arranging the filter 154 that is recessed toward the inside of the air inlet 1524, it is helpful to increase the contact area between the oil fume and the filter 154, and by increasing the probability of the oil in the oil fume colliding with the filter 154, the probability of the filter 154 capturing the oil is increased. , thereby improving the separation effect of the separation assembly 150 on grease.

It can be seen that by arranging the recessed filter screen 154, the grease content in the oil fume passing through the filter screen 154 can be reduced, thereby reducing the oil content contained in the final discharged air flow and weakening the air flow's ability to pollute the indoor environment. . On the other hand, it can reduce the accumulation speed of oil dirt inside the range hood equipment, thereby reducing the possibility of short circuit, leakage or fire in the electrical components inside the equipment due to oil corrosion, and at the same time prolongs the internal cleaning cycle of the range hood equipment and reduces the frequency of user cleaning. This solves the technical problems existing in related technologies: serious pollution of the environment by the exhaust air flow, poor safety and reliability, high failure rate, high cleaning frequency, and poor user experience. This further achieves the technical effect of optimizing the structure of the separation component 150, improving the grease separation performance of the separation component 150, improving the safety and reliability of range hood equipment, and providing convenient conditions for users.

As shown in Figures 25, 26 and 28, in one embodiment of the present application, the filter screen 154 is cut through a plane perpendicular to the length direction of the bracket 152. On the resulting cross section, the filter screen 154 is symmetrically distributed. Among them, the direction of the arrow in Figure 25 is the flow direction of oil fume.

In this embodiment, the shape of the filter element is defined. For example, the filter screen 154 is cut through a plane perpendicular to the length direction of the bracket 152. In the obtained cross section, the left and right ends of the filter screen 154 are close to the air inlet 1524, and the middle part is recessed in a direction away from the air inlet 1524, and The filters 154 are symmetrically distributed on both sides of the center line of the bracket 152 . By arranging symmetrically distributed filters 154, the flow field characteristics of the internal space of the separation component 150 can be optimized, thereby reducing the resistance produced by the filter 154 to the oil fume, thereby increasing the air volume in the separation component 150, thereby improving the extraction of oil fume by the range hood equipment. Ability. At the same time, the symmetrically distributed filters 154 can also reduce the possibility of turbulence or vortex around the filter 154, thereby reducing aerodynamic noise and improving user experience. Thereby, the technical effects of optimizing the shape of the filter 154, reducing the wind resistance of the filter 154, increasing the separation air volume, and enhancing the fume extraction performance of the range hood equipment are achieved.

As shown in Figures 24 and 25, in any of the above embodiments, in cross-section, the filter screen 154 includes: a first section 1542 extending in a straight direction; a second section 1544 connected with the first section 1542.

In this embodiment, following the previous embodiment, the shape of the filter screen 154 is described in detail. For example, on the obtained cross-section, a first section 1542, a second section 1544 and a third section 1546 are divided on the filter screen 154 according to the shape. The first section 1542 and the second section 1544 are located on the left and right sides of the third section 1546, and both the first section 1542 and the second section 1544 extend in a straight direction, with one end close to the air inlet 1524 and away from the air inlet 1524. One end of the air inlet 1524 is connected to the third section 1546 . By arranging the linearly extending first section 1542 and the second section 1544 in the left and right areas of the filter screen 154, the matching degree between the filter screen 154 and the flow direction of the oil smoke can be further improved to increase the contact area between the oil smoke and the filter screen 154, thereby improving the The ability of the filter 154 to capture grease particles. This further achieves the technical effect of optimizing the shape of the filter 154, improving the oil separation effect of the separation component 150, and improving the safety and reliability of the range hood equipment.

In any of the above embodiments, the range of the angle between the first section 1542 and the second section 1544 is: greater than or equal to 30° and less than or equal to 100°.

In this embodiment, following the previous embodiment, the positional relationship between the first section 1542 and the second section 1544 is limited. For example, the angle between the first section 1542 and the second section 1544 that are symmetrically arranged and extend in a straight direction needs to be greater than or equal to 30° and less than or equal to 100°. By limiting the angle a between the first section 1542 and the second section 1544 to between 30° and 100°, it helps to improve the capture capacity of the filter 154 for grease particles, thereby improving the oil separation of the separation assembly 100 The effect is to improve the safety and reliability of related products.

In this embodiment, a second shape of filter screen 154 is proposed. For example, in the obtained cross-section, the filter screen 154 has an overall arc shape. The surface of the filter screen 154 that contacts the oil fume is a smooth transition surface. Therefore, by setting the filter screen 154 with an arc-shaped cross section, the friction between the oil smoke and the filter screen 154 can be reduced on the basis of increasing the contact area between the oil smoke and the filter screen 154. . Thereby, the aerodynamic resistance of the separation component 150 is reduced to increase the air volume circulating inside the separation component 150 . This achieves the technical effect of optimizing the shape of the filter 154 and improving the ability of the associated equipment to extract oil smoke.

As shown in FIG. 28 , in any of the above embodiments, the filter screen 154 is V-shaped in cross section.

In this embodiment, a third shape of filter 154 is proposed. For example, in the resulting cross-section, the filter screen 154 is V-shaped as a whole. The filter screen 154 with a V-shaped cross-section guides the separated grease. The oil pollution particles attached to the filter screen 154 can quickly collect to the bottom of the filter screen 154 under the slope of the V-shaped filter screen 154, and finally drip through the bottom of the filter screen 154. It can be seen that by arranging the filter 154 with a V-shaped cross-section, the grease export efficiency can be accelerated on the basis of increasing the contact area between the oil fume and the filter 154, and preventing a large amount of grease accumulated on the filter 154 from affecting the filter 154. Permeability. Then, the technical effect of optimizing the shape of the filter screen 154, improving the practicality and reliability of the filter screen 154, and enhancing the grease separation performance of the separation component 150 is achieved.

The filter 154 is shaped. Specifically, the filter screen 154 can be bonded to the groove 1562 with glue to prevent the filter screen 154 from being deformed by external factors such as vibration. It can be seen that by providing the groove 1562, the filter screen 154 can be maintained in an effective separation shape for a long time, thereby improving the stability of the filter screen 154 in separating grease.
