Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to an integrated stove. Background Technology

[0002] Cooking produces a lot of oil fumes, and prolonged exposure to these fumes can harm a user's health. Furthermore, the fumes adhere to cookware and walls, making cleaning difficult. Therefore, most families install range hoods to alleviate this problem. Integrated cooktops, which combine a range hood, cooktop, disinfection cabinet, and steam oven into one appliance, offer advantages such as space saving, effective fume extraction, energy efficiency, and environmental friendliness, making them a top choice for many families during renovations.

[0003] Existing integrated cooktops typically include a casing, cooktop module, air duct module, air box module, and exhaust module. Cooking fumes generated when the user operates the cooktop module are sequentially introduced into the casing, air duct module, and air box module under the negative pressure of the air box module, before being exhausted through the exhaust module into a common exhaust duct, thus purifying the kitchen air. However, after prolonged use, oil leaks are prone to occur at the exhaust module, affecting the cleanliness of the user's kitchen and causing significant inconvenience for cleaning.

[0004] Therefore, there is an urgent need to develop an integrated stove to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated stove that can avoid oil leakage at the exhaust module, reduce the user's cleaning work, and improve the user experience.

[0006] Based on the above concept, the technical solution adopted by this invention is as follows:

[0043] 500-Stove Module. Detailed Implementation

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0048] Figure 1 A schematic diagram of the integrated stove provided in this embodiment is shown. Figure 2 A partial cross-sectional view of the integrated stove provided in this embodiment is shown. Figures 1-2As shown, this embodiment provides an integrated stove, which includes a housing 100, an air duct module 200, an air box module 300, a smoke exhaust module 400, and a stove module 500. The stove module 500 is mounted on the housing 100, and a smoke inlet is provided on the top of the housing 100. The air duct module 200 is erected inside the housing 100, and a smoke exhaust duct 201 is provided through the air duct module 200, which is connected to the smoke inlet on the housing 100. The air box module 300 is horizontally placed at the bottom of the housing 100. The air box module 300 includes a housing 2 and a fan 1 disposed inside the housing 2. The housing 2 is provided with a smoke inlet 22 that is connected to the outlet of the smoke exhaust duct 201. The housing 2 is also provided with a smoke outlet 23, and the inlet of the smoke exhaust module 400 passes through the smoke outlet 23 and is connected to the outlet of the fan 1. When a user cooks using the cooktop module 500, starting the fan 1 creates negative pressure in the air box module 300 and the air duct module 200. This causes the fumes generated by the cooktop module 500 to pass sequentially through the smoke inlet, the smoke duct 201, and the air box module 300 before being discharged into the common exhaust duct through the exhaust module 400, thereby purifying the kitchen air.

[0049] Figure 3 An exploded view of the bellows module 300 provided in this embodiment is shown. Figure 4 A schematic diagram of the internal structure of the housing 2 provided in this embodiment is shown. (See attached diagram.) Figures 3-4 As shown, the front end of the housing 2 is provided with a loading / unloading port 21. The fan 1 is slidably disposed in the housing 2 and can be disassembled from the loading / unloading port 21, thus facilitating maintenance personnel to repair the fan 1 without moving the integrated stove. Optionally, a fan box cover 24 is detachably connected to the loading / unloading port 21. The fan box cover 24 is used to seal the loading / unloading port 21 to ensure a negative pressure environment in the entire fume duct. In this embodiment, the fan box cover 24 is installed at the loading / unloading port 21 with screws, which is simple in structure and easy to disassemble and assemble.

[0050] Figure 5 A schematic diagram showing the positional relationship between the diffuser connector seat 401 and the fixing seat 402 provided in this embodiment is shown. Figure 5 and combined Figure 1 As shown, the smoke exhaust module 400 includes a diffuser connector 401, a fixed base 402, and an exhaust pipe assembly 403, which are separately arranged and connected in sequence. The end of the diffuser connector 401 away from the fixed base 402 is connected to the outlet of the fan 1. The separate arrangement of the smoke exhaust module 400 facilitates processing and assembly, improving the assembly efficiency of the integrated stove. By setting the diffuser connector 401, some of the kinetic energy in the fan 1 can be converted into static pressure, ensuring that the fumes can be smoothly discharged into the common smoke exhaust duct through the smoke exhaust module 400.

[0051] In this embodiment, the cross-sectional shape of the outlet of the fan 1 is rectangular. Adaptively, the cross-sectional shapes of the smoke outlet 23, the diffuser connector 401, the fixing seat 402, and the end of the exhaust pipe assembly 403 near the fixing seat 402 on the housing 2 are all rectangular. This design facilitates assembly, allowing operators to quickly identify the vertical orientation of the diffuser connector 401, the fixing seat 402, and the exhaust pipe assembly 403, thereby improving assembly accuracy and efficiency.

[0052] Figure 6 A cross-sectional view of the bellows module 300 and the smoke exhaust module 400 provided in this embodiment is shown. Figure 7 yes Figure 6 A magnified view of a portion at point A. (See attached image.) Figures 6-7 and combined Figure 4 As shown, the housing 2 is also equipped with an oil collection port 26, which is located below the smoke outlet 23. The bottom of the smoke exhaust module 400 is equipped with an oil collection channel 4020, which is connected to the housing 2. When the fan 1 starts, a negative pressure environment is formed inside the housing 2, and a negative pressure environment is also formed inside the oil collection channel 4020 connected to the housing 2. When the smoke exhaust module 400 leaks oil, under the action of negative pressure, the leaked oil can be drawn back into the housing 2, preventing leakage from the various connections of the smoke exhaust module 400. Optionally, a pull-out oil collection trough can be provided in the housing 2 to collect the oil drawn back from the oil collection channel 4020. Users can clean this oil regularly to maintain the cleanliness of the integrated stove. In this embodiment, the oil collection channel 4020 is located at the bottom of the fixed base 402, and the exhaust pipe assembly 403 is connected to the end of the oil collection channel 4020 away from the housing 2.

[0053] In existing integrated cooktop technology, the lowest point of the exhaust module 400 often interferes with standard kitchen cabinets during installation, requiring partial removal of the cabinet base to meet installation requirements. This is time-consuming, labor-intensive, and costly. To solve this problem, such as... Figure 5 and Figure 6 As shown, the mounting base 402 includes a first main body 4021 and an inlet end 4022 and an outlet end 4023 respectively connected to the two ends of the first main body 4021. The inlet end 4022 is connected to the diffuser connector 401, and the outlet end 4023 is connected to the exhaust pipe assembly 403. The bottom surface of the first main body 4021 gradually slopes upward in the direction away from the fan 1 so that the lowest position of the smoke exhaust module 400 is higher than the bottom plate of the standard cabinet in the user's kitchen, thereby preventing the smoke exhaust module 400 from interfering with the bottom plate of the cabinet when installing the integrated stove. That is, the integrated stove can be installed without removing part of the cabinet bottom plate, which saves time and effort and has a low installation cost.

[0054] In this embodiment, the angle between the bottom surface of the first main body 4021 and the horizontal plane is 8° to 12°. This angle ensures sufficient clearance between the exhaust module 400 and the cabinet bottom plate for quick installation of the entire integrated stove. Optionally, the angle between the bottom surface of the first main body 4021 and the horizontal plane can be 9°, 9.5°, 10°, 10.5°, 11°, 11.5°, etc., reducing the tilt angle of the first main body 4021 while ensuring sufficient clearance between the exhaust module 400 and the cabinet bottom plate, thus ensuring a stable connection between the entire exhaust module 400 and the air box module 300.

[0055] To ensure a smooth transition for the smoke exhaust module 400, the diffuser connector 401 includes a second main body 4011 and a first connecting end 4012 and a second connecting end 4013 respectively connected to both ends of the second main body 4011. The first connecting end 4012 is connected to the outlet flange of the fan 1, and the second connecting end 4013 is connected to the inlet end 4022. The bottom surface of the second main body 4011 gradually slopes upward in the direction away from the fan 1.

[0056] In this embodiment, the angle between the bottom surface of the second main body 4011 and the horizontal plane is 3° to 5°. Preferably, the angle between the bottom surface of the second main body 4011 and the horizontal plane is 3.5°, 3.5°, 4°, or 4.5°. In this embodiment, the entire smoke exhaust module 400, from the outlet flange of the fan 1 to the outlet end 4023 of the fixed seat 402, adopts an upward angle design that transitions from 4.5° to 10°. On the one hand, this ensures that when the integrated stove is installed, even after the fan box module 300 is lowered by 30mm, there is still sufficient clearance between the smoke exhaust module 400 and the cabinet bottom plate, preventing interference between the smoke exhaust module 400 and the cabinet bottom plate; on the other hand, it ensures the stability of the entire inclined smoke exhaust module 400.

[0057] Figure 8 A partial cross-sectional view of the diffuser connector seat 401 provided in this embodiment is shown. Figure 9 It shows Figure 8 A magnified view of point B. (See attached image.) Figures 8-9 and combined Figure 3As shown, to ensure accurate docking of the fan 1 with the smoke exhaust module 400 during reinstallation, a U-shaped slot 40121 is provided at the inlet of the diffuser connector 401. The U-shaped opening of the slot 40121 faces forward, allowing the outlet flange of the fan 1 to be accommodated within it. When the fan 1 is disassembled and reinstalled, its outlet flange can be aligned with the U-shaped opening of the slot 40121 for insertion, ensuring accurate docking of the fan 1's outlet with the smoke exhaust module 400 after installation. This meets the installation accuracy requirements of the interface after the fan 1 is pushed into the housing 2, preventing smoke leakage. Optionally, the U-shaped opening of the slot 40121 is flared to facilitate quick insertion of the fan 1's outlet flange into the slot 40121.

[0058] It should be noted that in this embodiment, the angle between the bottom of the U-shaped groove 40121 and the vertical plane is 2° to 4°; the end face of the outlet flange of the fan 1 can fit against the bottom of the U-shaped groove 40121. Preferably, the angle between the bottom of the U-shaped groove 40121 and the vertical plane is 3°. On the one hand, this ensures the tilt requirement of the entire smoke exhaust module 400 while meeting the installation accuracy requirements of the interface after the fan 1 is pushed into the housing 2; on the other hand, the outlet flange of the fan 1 does not need to be connected with screws when it is fitted with the diffuser connector seat 401, which can save the time of drilling holes in the fan 1 and the diffuser connector seat 401, improve processing efficiency, and maintain the integrity of the fan 1, thus extending its service life. In this embodiment, the height of each wall of the second connection end 4013 is flush with the height of the corresponding walls of the inlet end 4022, so as to facilitate the assembly between the diffuser connector seat 401 and the fixed seat 402.

[0059] To ensure a tight seal between the diffuser connector seat 401 and the outlet flange of the fan 1, a diffuser seal 40122 is provided between the diffuser connector seat 401 and the outlet flange of the fan 1. Optionally, a diffuser sealing groove 40123 is provided on the end face of the first connection end 4012 near the fan 1, and the diffuser seal 40122 is housed in the diffuser sealing groove 40123 to ensure the installation stability of the diffuser seal 40122 and prevent the diffuser seal 40122 from falling off during disassembly of the fan 1. In this embodiment, the diffuser seal 40122 is interference-fitted into the diffuser sealing groove 40123 to further prevent the diffuser seal 40122 from falling off.

[0060] Furthermore, the diffuser seal 40122 includes a sealing body and a sealing rib protruding from the sealing body. The sealing body is housed in the diffuser sealing groove 40123, and the sealing rib can abut against the end face of the outlet flange of the fan 1. This design can transform the surface seal between the fan 1 and the diffuser connector 401 into a linear seal, thereby meeting the airtightness requirements after the two are connected, ensuring no oil fume leakage at the connection, and preventing the fan 1 from being difficult to disassemble due to excessive sealing force. Optionally, there can be multiple sealing ribs, which are spaced apart along the thickness direction of the sealing body to improve the sealing performance between the fan 1 and the diffuser connector 401.

[0061] Figure 10 It shows Figure 6 A magnified view of point C. (See attached image.) Figure 6 and Figure 10 and combined Figure 3 As shown, a positioning protrusion 25 is provided on the outer wall of the housing 2 around the outer periphery of its smoke outlet 23. The second connecting end 4013 of the diffuser connector seat 401 passes through the positioning protrusion 25, and the inlet end 4022 of the fixed seat 402 is sleeved on the outside of the positioning protrusion 25. By providing the positioning protrusion 25 on the outer wall of the housing 2, the positioning accuracy between the diffuser connector seat 401 and the housing 2, between the fixed seat 402 and the housing 2, and between the diffuser connector seat 401 and the fixed seat 402 can be guaranteed.

[0062] To further ensure the stability of the connection between the diffuser connector 401 and the housing 2, as well as between the fixed seat 402 and the housing 2, the second connection end 4013 is fixedly connected to the housing 2 by screws; the inlet end 4022 is fixedly connected to the housing 2 by screws. Screw connection has the advantages of simple processing and stable connection.

[0063] To ensure a tight seal between the diffuser connector 401 and the fixed seat 402, a fixing seal 40221 is provided between them. Specifically, the inlet end 4022 of the fixed seat 402 has a fixing sealing groove 40222, a positioning protrusion 25 is inserted into the fixing sealing groove 40222, and the fixing seal 40221 is housed within the fixing sealing groove 40222, with both ends of the fixing seal 40221 abutting against the positioning protrusion 25 and the inlet end 4022, respectively. Optionally, the fixing seal 40221 is interference-fitted into the fixing sealing groove 40222 to ensure the sealing between the diffuser connector 401 and the fixed seat 402 and the stability of the fixing seal 40221, preventing the fixing seal 40221 from falling off.

[0064] In this embodiment, the fixed seal 40221 has a V-shaped cross-section. After the positioning protrusion 25 is inserted into the fixed sealing groove 40222, it can compress the fixed seal 40221, thereby improving the sealing performance between the diffuser connector seat 401 and the fixed seat 402 by increasing the compression ratio. Optionally, the fixed seal 40221 is made of silicone foam material.

[0065] Figure 11 An exploded view of the mounting base 402 provided in this embodiment is shown. Figure 12 A partial cross-sectional view of the mounting base 402 provided in this embodiment is shown. Figure 13 It shows Figure 12 A magnified view of a portion at point D. Figure 14 An exploded view of the exhaust pipe assembly 403 provided in this embodiment is shown. Figures 11-14 and combined Figure 1 As shown, the outlet end 4023 of the fixed base 402 is provided with an assembly groove 40233, and the exhaust pipe assembly 403 can be inserted into the assembly groove 40233, which can realize the quick assembly between the fixed base 402 and the exhaust pipe assembly 403.

[0066] In this embodiment, the exhaust pipe assembly 403 includes a connecting seat 4031 and an exhaust pipe 4032. The first end of the connecting seat 4031 has a rectangular cross-sectional shape to be inserted into the outlet end 4023 of the fixing seat 402. The second end of the connecting seat 4031 has a circular cross-sectional shape to connect the exhaust pipe 4032. Optionally, a clamp 4033 is also provided between the connecting seat 4031 and the exhaust pipe 4032 to ensure the stability of the connection. Optionally, the exhaust pipe 4032 is a foldable aluminum foil tube, which can adjust its length according to the size of the kitchen space to improve its versatility.

[0067] To ensure a tight seal between the mounting base 402 and the exhaust pipe assembly 403, an exhaust seal 40231 is provided between them. Specifically, the exhaust seal 40231 includes a first seal 402311, which is housed at the bottom of the mounting groove 40233. The first seal 402311 abuts against the end face of the exhaust pipe assembly 403, thereby ensuring a tight seal between the connecting end faces of the mounting base 402 and the exhaust pipe assembly 403. Optionally, the first seal 402311 is interference-fitted into the mounting groove 40233, which, while ensuring a tight seal between the mounting base 402 and the exhaust pipe assembly 403, also prevents the first seal 402311 from falling off. In this embodiment, the first sealing member 402311 has a U-shaped cross-section, meaning it is hollow inside. After the exhaust pipe assembly 403 is inserted into the fixing seat 402, the first sealing member 402311 can be compressed to improve the sealing performance between the fixing seat 402 and the exhaust pipe assembly 403 by increasing the compression ratio. Optionally, the first sealing member 402311 is made of silicone foam material.

[0068] Furthermore, the exhaust seal 40231 includes a second seal 402312, which is disposed on the groove wall of the mounting groove 40233 and the side wall of the exhaust pipe assembly 403, thereby ensuring the sealing between the connecting side walls of the fixing seat 402 and the exhaust pipe assembly 403. Through the mutual cooperation between the first seal 402311 and the second seal 402312, the sealing between the fixing seat 402 and the exhaust pipe assembly 403 is ensured, preventing smoke leakage. Optionally, the groove wall of the mounting groove 40233 is further provided with an exhaust sealing groove 40232 to accommodate the second seal 402312, ensuring the stability of the second seal 402312 and preventing it from falling off. Further optionally, the second seal 402312 is interference-fitted into the exhaust sealing groove 40232. In this embodiment, the second seal 402312 is made of silicone material and is adhered to the exhaust sealing groove 40232, which facilitates assembly and ensures a stable connection.

[0069] Of course, in other embodiments, either the first seal 402311 or the second seal 402312 can be provided, and the above effect can be achieved in the same way.

[0070] It should be noted that the specific structure of the second seal 402312 is the same as that of the diffuser seal 40122, the difference being the installation direction. The sealing body of the second seal 402312 is housed in the exhaust sealing groove 40232. The sealing rib of the second seal 402312 can press against the outer wall of the exhaust pipe assembly 403 after the exhaust pipe assembly 403 is inserted into the fixing seat 402, so as to achieve the effect of secondary sealing and mutual compensation, further improving the sealing performance at the interface between the exhaust pipe assembly 403 and the fixing seat 402.

[0071] In this embodiment, a rectangular connection port is provided on the chassis 100 corresponding to the fixing seat 402. The fixing seat 402 is located inside the chassis 100, and most of the exhaust pipe assembly 403 is located outside the chassis 100. The exhaust pipe assembly 403 passes through the connection port on the chassis 100 and is inserted into the fixing seat 402 (see reference).
