Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen appliances, and in particular relates to a smoke and stove integrated machine. Background Art

[0002] Range hoods and gas stoves, essential core appliances in modern kitchens, are widely used in homes and restaurants, their performance directly impacting cooking efficiency and user experience. Traditionally, range hoods utilize a split design, requiring the range hood to be hung vertically above the stovetop, occupying significant overhead space and disrupting the kitchen's visual integrity. The gas stove is recessed horizontally into the countertop, compressing the operating area. This combined installation not only results in poor space utilization but also restricts kitchen movement and significantly diminishes the kitchen's aesthetics. Furthermore, users must frequently perform tedious maintenance, such as daily cleaning of residual oil from the oil screen, regularly emptying the oil collection box, and scrubbing the stovetop surface. This accumulation of grease and dirt results in a poor cleaning experience and poses a hygienic hazard. While some integrated range hood and stove products exist on the market, these remain fixed to the split design and remain constrained by inherent limitations in space and manual cleaning. Summary of the Invention

[0003] In view of this, the present invention provides an all-in-one range hood and gas stove, which solves the technical problems of traditional range hoods and gas stoves taking up a large space and requiring cumbersome manual cleaning due to their split design.

[0004] In order to solve the above problems, according to one aspect of the present application, an embodiment of the present invention provides a smoke and stove all-in-one machine, which includes a fan module, a smoke hood, a stove assembly and a self-cleaning assembly. The smoke hood is connected to the fan module, and the smoke hood has a smoke inlet channel. The stove assembly is connected under the smoke hood, and it has a closed state covering the smoke inlet channel and an expanded state exposing the smoke inlet channel. The input end of the self-cleaning assembly is connected to a water source, and the output end of the self-cleaning assembly is located in the smoke hood and can spray water toward the stove assembly in a closed state.

[0005] In some embodiments, the self-cleaning component includes a spray module and a pressurizing module, one end of the pressurizing module is connected to the water source through a water inlet interface, and the other end of the pressurizing module is connected to the input end of the spray module through a connecting water pipe, and the output end of the spray module is facing the stove assembly in a closed state.

[0006] In some embodiments, the self-cleaning assembly further includes a heating module, and the heating module is located between the water inlet interface and the pressurizing module.

[0007] In some embodiments, the spraying module includes a water inlet pipe, a rotating support, a spraying wall, and spraying holes. The water inlet pipe is connected to the connecting water pipe. The spraying wall is rotatably connected to the water inlet pipe through the rotating support. The spraying holes are formed in the spraying wall and there are multiple spraying holes. When water flows out through the spraying holes, it can drive the spraying wall to rotate.

[0008] In some embodiments, the cooking appliance assembly includes at least one burner and a driving module. The driving module connects the burner and the smoke collecting hood and is configured to drive the burner to switch between a closed state and an unfolded state.

[0009] In some embodiments, the driving module includes a rotating motor which can drive the burner to open to a drying angle. The drying angle is greater than 0° and less than the angle in the unfolded state.

[0010] In some embodiments, an installation interface is provided on the smoke collecting hood. The fan module is detachably fixed above the installation interface through a sealing structure. The smoke collecting hood is installed between the wall cabinets.

[0011] In some embodiments, the integrated range hood and stove further includes a range hood and stove interlock control component. The range hood and stove interlock control component is configured to: upon the cooking appliance assembly switching from the closed state to the unfolded state, start the fan module; and upon the cooking appliance assembly switching back from the unfolded state to the closed state, automatically turn off the fan module or turn off the fan module after a preset time.

[0012] In some embodiments, the self-cleaning component further includes a drying control component. After the self-cleaning component completes the cleaning operation, the drying control component can control the fan module to start and control the cooking appliance assembly to open to the drying angle to introduce air.

[0013] In some embodiments, a drain port is provided at the bottom of the smoke collecting hood. The drain port is communicated with the sewer to discharge the sewage generated during the cleaning process.

[0014] Compared with the prior art, the integrated range hood and stove of the present invention has at least the following beneficial effects: The integrated range hood and stove provided by the present invention includes a fan module, a smoke collecting hood, a cooking appliance assembly, and a self-cleaning component. The smoke collecting hood is connected to the fan module. The smoke collecting hood has a smoke inlet passage. The cooking appliance assembly is connected below the smoke collecting hood and has a closed state covering the smoke inlet passage and an unfolded state exposing the smoke inlet passage. The input end of the self-cleaning component is connected to a water source. The output end of the self-cleaning component is located inside the smoke collecting hood and can spray water towards the cooking appliance assembly in the closed state.

[0015] When the integrated range hood and stove works, the stove component is first in the unfolded state, exposing the smoke inlet channel. The user performs cooking operations, and the generated oil fumes are collected by the smoke collecting hood and guided through the smoke inlet channel to the fan module. After the fan module starts, it sucks and discharges the oil fumes, completing the oil fume treatment. During the cleaning stage, the stove component switches to the closed state, covering the smoke inlet channel. At this time, the self-cleaning component starts, and its output end sprays water on the stove component in the closed state. The water flow flushes the surface of the stove and the inner area of the smoke collecting hood, dissolving the oil stains and taking them away by the drainage system. The whole process realizes the seamless connection between oil fume suction and exhaust and automatic cleaning. Through the integrated integration of the fan module, smoke collecting hood, smoke inlet channel, stove component, and self-cleaning component, the present invention solves the problems of large space occupation of traditional split designs and cumbersome manual cleaning: the stove component is directly connected below the smoke collecting hood and covers the smoke inlet channel in the closed state, saving vertical space during non-cooking and reducing the overall kitchen occupation; at the same time, the self-cleaning component automatically sprays water for cleaning in the closed state of the stove component, directly acting on the surface of the stove and the inner part of the smoke collecting hood, without the need for the user to manually wipe or disassemble parts, significantly reducing the maintenance frequency and cleaning difficulty, thereby improving the space utilization rate and hygiene experience.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0023] This embodiment provides an integrated range hood and stove, as Figures 1 - 18 shown. The integrated range hood and stove includes a fan module 1, a smoke collecting hood 2, a stove component 3, and a self-cleaning component 4. The smoke collecting hood 2 is connected to the fan module 1. The smoke collecting hood 2 has a smoke inlet passage 21. The stove component 3 is connected below the smoke collecting hood 2 and has a closed state covering the smoke inlet passage 21 and an unfolded state exposing the smoke inlet passage 21. The input end of the self-cleaning component 4 is connected to a water source, and the output end of the self-cleaning component 4 is located inside the smoke collecting hood 2 and can spray water towards the stove component 3 in the closed state. Among them, the stove component 3 is located on a base cabinet 6.

[0024] The fan module 1 is directly connected to the top of the smoke collecting hood 2, forming part of the flue system; inside the smoke collecting hood 2, there is a smoke inlet channel 21, which serves as the path for the flow of cooking fumes; the cooking appliance assembly 3 is fixedly connected below the smoke collecting hood 2, and its position is designed such that the cooking appliance assembly 3 can move upward to cover the smoke inlet channel 21 in the closed state, or move downward to expose the smoke inlet channel 21 in the unfolded state, thereby realizing space conversion; the input end of the self-cleaning component 4 is connected to an external water source, and its output end is installed inside the smoke collecting hood 2 and faces the direction of the cooking appliance assembly 3, so as to directly spray water on its surface when the cooking appliance assembly 3 is in the closed state. All components are integrated into one body through a mechanical structure to achieve a compact layout.

[0025] The function of the fan module 1 is to provide suction power to inhale and discharge the cooking fumes outdoors; the function of the smoke collecting hood 2 is to collect the fumes and direct the fumes to the fan module 1 through its structure; the smoke inlet channel 21, as part of the smoke collecting hood 2, serves to form a channel for the fumes to enter the fan module 1 to ensure the efficient flow of fumes; the function of the cooking appliance assembly 3 is to provide cooking functions, support the user for heating operations, and can cover the smoke inlet channel 21 in the closed state to assist in cleaning, and expose the smoke inlet channel 21 in the unfolded state to allow the fumes to be inhaled; the function of the self-cleaning component 4 is to automatically perform the cleaning task, and remove the oil stains in the areas of the cooking appliance assembly 3 and the smoke collecting hood 2 by spraying water, reducing manual intervention.

[0026] When the integrated range hood and stove works, the cooking appliance assembly 3 is first in the unfolded state, exposing the smoke inlet channel 21. The user performs cooking operations, and the generated fumes are collected by the smoke collecting hood 2 and directed to the fan module 1 through the smoke inlet channel 21. After the fan module 1 is started, it sucks and discharges the fumes to complete the fume treatment; in the cleaning stage, the cooking appliance assembly 3 switches to the closed state, covering the smoke inlet channel 21. At this time, the self-cleaning component 4 is started, and its output end sprays water on the closed cooking appliance assembly 3. The water flow flushes the surface of the cooking appliance and the inner area of the smoke collecting hood 2, dissolves the oil stains, and is taken away by the drainage system. The whole process realizes the seamless connection between fume suction and exhaust and automatic cleaning.

[0027] In this embodiment, through the integrated integration of the fan module 1, the smoke collecting hood 2, the smoke inlet channel 21, the cooking appliance assembly 3 and the self-cleaning component 4, the problems of large space occupation of the traditional split design and cumbersome manual cleaning are solved: the cooking appliance assembly \alpha is directly connected below the smoke collecting hood 2 and covers the smoke inlet channel 21 in the closed state, saving vertical space during non-cooking and reducing the overall kitchen occupation; at the same time, the self-cleaning component 4 automatically sprays water for cleaning in the closed state of the cooking appliance assembly 3, directly acting on the surface of the cooking appliance and the inner part of the smoke collecting hood 2, without the need for the user to manually wipe or disassemble the components, significantly reducing the maintenance frequency and cleaning difficulty, thereby improving the space utilization rate and sanitation experience.

[0028] In a specific embodiment, such as Figure 9As shown, the self-cleaning component 4 includes a spraying module 41 and a pressurizing module 42. One end of the pressurizing module 42 is connected to a water source through a water inlet interface 43, and the other end of the pressurizing module 42 is connected to the input end of the spraying module 41 through a connecting water pipe 44. The output end of the spraying module 41 faces the cooking appliance component 3 in a closed state.

[0029] The water inlet interface 43 is located at the starting end of the self-cleaning component 4 and is directly connected to an external water source. The input end of the pressurizing module 42 is communicated with the water inlet interface 43 through a pipeline, and its output end is connected to the input end of the spraying module 41 through a connecting water pipe 44. The spraying module 41 is fixedly installed inside the smoke collecting hood 2, and its output end (spray nozzle) faces the surface of the cooking appliance component 3 in a closed state below or on the side. An overall continuous water path of "water source, water inlet interface 43, pressurizing module 42, connecting water pipe 44, spraying module 41" is formed.

[0030] The water inlet interface 43 is responsible for introducing the external water source into the self-cleaning component 4; the pressurizing module 42 pressurizes the flowing water to increase the water flow speed and impact force; the connecting water pipe 44 serves as a sealed transmission channel to transmit the pressurized water flow from the pressurizing module 42 to the spraying module 41; the spraying module 41 then converts the pressurized water flow into a directionally sprayed water mist or water column through its output end to cover the surface of the cooking appliance component 3 when it is closed and the area inside the smoke collecting hood 2, realizing the dissolution and flushing of oil stains.

[0031] When the self-cleaning component 4 is started, the external water source flows in through the water inlet interface 43. The water flow first enters the pressurizing module 42 and is pressurized, and then is transported to the spraying module 41 through the connecting water pipe 44. After receiving the pressurized water flow, the spraying module 41 sprays high-pressure water flow onto the surface of the cooking appliance component 3 in a closed state and the inner wall of the smoke collecting hood 2 through its output end. The water flow directly impacts and dissolves the oil stains, and the dirty liquid flows away along the drainage path, completing the cleaning process without manual intervention.

[0032] The self-cleaning component 4 provided in this embodiment improves the cleaning efficiency: the water inlet interface 43 ensures the stable access of the water source; the pressurizing module 42 enhances the water flow power and solves the problem of insufficient scouring force of ordinary water flow; the connecting water pipe 44 realizes sealed and efficient water transmission; the spraying module 41 then sprays precisely and directionally to ensure that the surface of the cooking appliance component 3 in a closed state and the inside of the smoke collecting hood 2 are fully covered. The four work together to achieve a high-pressure, directional, and automated cleaning effect, significantly reducing oil stain residues and reducing manual operations.

[0033] In addition, the core function of the pressurizing module 42 is to provide pressurizing power for the water flow, and its specific implementation form can be a pressurizing water pump that pressurizes the water flow by driving an impeller or a piston through a motor.

[0034] In a specific embodiment, the self-cleaning component 4 further includes a heating module 45, and the heating module 45 is located between the water inlet interface 43 and the pressurizing module 42.

[0035] The heating module 45 is serially installed in the water path of the self-cleaning component 4. Its input end is directly connected to the water inlet interface 43 to receive the inflow of external water source, and its output end is communicated with the input end of the pressurizing module 42, forming a fixed sequence of "water inlet interface 43, heating module 45, pressurizing module 42". This position ensures that the water flow is heated by the heating module 45 before entering the pressurizing module 42, so as to provide high-temperature water flow in the subsequent process.

[0036] The core function of the heating module 45 is to instantaneously heat the water flow. Its typical implementation form is an instant water heater with built-in electric heating tubes. The heat pipe surface is rapidly heated by current and transfers the heat to the flowing water body. In addition, a PTC heater or a micro-channel metal plate heating structure can also be used.

[0037] The heating module 45 instantaneously heats the inflowing cold water into high-temperature water flow, significantly improving the cleaning efficiency: the high temperature can quickly soften and dissolve the stubborn oil stains attached to the surface of the cooking appliance component 3 and inside the smoke hood 2. At the same time, the molecular activity of the high-temperature water flow is enhanced, which can improve the penetration and emulsification decomposition efficiency of the oil stains. Combined with the high-pressure spraying of the subsequent pressurizing module 42, a synergistic effect of "high-temperature softening plus high-pressure scouring" is formed, thoroughly removing the sticky oil stains that are difficult to handle by traditional cold water cleaning, greatly reducing the cleaning time and reducing the residue risk, so as to achieve a more thorough and energy-saving automatic cleaning effect.

[0038] In a specific embodiment, as Figures 16 - 18 shown, the spraying module 41 includes a water inlet pipe 411, a rotating support 412, a spraying wall 413 and spraying holes 414. The water inlet pipe 411 is connected to the connecting water pipe 44. The spraying wall 413 is rotatably connected to the water inlet pipe 411 through the rotating support 412. The spraying holes 414 are opened on the spraying wall 413 and there are multiple of them. Among them, when the water flows out through the spraying holes 414, it can drive the spraying wall 413 to rotate.

[0039] The water inlet pipe 411 is directly connected to the connecting water pipe 44 to serve as the water flow inlet; the rotary support 412 is fixed on the water inlet pipe 411 to provide rotational support; the spray wall 413 is rotatably connected to the water inlet pipe 411 through the rotary support 412, enabling the spray wall 413 to rotate relative to the water inlet pipe 411; the spray holes 414 are formed in the spray wall 413 and are distributed with multiple hole positions. The water inlet pipe 411 is located upstream, and the spray wall 413 is suspended below the water inlet pipe 411 through the rotary support 412, while the spray holes 414 are evenly distributed on the surface of the spray wall 413 to form the water flow outlet. The function of the water inlet pipe 411 is to receive the water flow flowing in from the connecting water pipe 44 and transport it to the inside of the spray module; the function of the rotary support 412 is to provide mechanical support and allow the spray wall 413 to achieve rotational motion; the function of the spray wall 413 is to serve as the main structure for water flow distribution and support the spray holes 414; the function of the spray holes 414 is to output the water flow in a jet form through multiple hole positions, and utilize the kinetic energy of the water flow to drive the rotation of the spray wall 413 during the jetting process, enhancing the water flow coverage area.

[0040] When the water flow enters the water inlet pipe 411 from the connecting water pipe 44, the water flow is directed to the spray wall 413 and ejected from the spray holes 414; the reaction force generated during the water flow jetting drives the spray wall 413 to rotate relative to the water inlet pipe 411 through the rotary support 412; the rotating spray wall 413 drives the movement of the spray holes 414, enabling the water flow to cover the target area in a rotating spray manner, achieving a dynamic and uniform spraying effect, thereby efficiently cleaning the surface of the cooking appliance assembly 3 and the inside of the smoke hood 2.

[0041] The spray module 41 provided in this embodiment automatically drives the rotation of the spray wall 413 by jetting water through the spray holes 414, without the need for an additional power source, to achieve dynamic spraying; the rotating spraying expands the water flow coverage area, reduces cleaning dead corners, and improves the oil stain dissolution and flushing efficiency; at the same time, the distribution of multiple spray holes 414 ensures the uniform distribution of the water flow, enhances the automation degree and cleaning thoroughness of the self-cleaning component, and reduces the need for manual intervention.

[0042] In addition, the rotating support member 412 is a fixing nut. As the core component of the rotating support member 412, the internal thread thereof is precisely matched with the external thread at the outer end of the water inlet pipe 411 to achieve rigid locking. A bushing structure is provided at the top of the spray wall 413. The bushing is nested on the outer periphery of the end of the water inlet pipe 411 through a bearing to form a rotatable connection. After the fixing nut is screwed tightly on the threaded section of the water inlet pipe 411, the bushing of the spray wall 413 is axially pressed against the positioning step of the water inlet pipe 411, restricting the axial displacement of the spray wall 413 but allowing it to freely rotate around the axis of the water inlet pipe 411. The spray holes 414 are formed on the circumferential wall surface of the spray wall 413 at a specific inclination angle. When high-pressure water flows through the water inlet pipe 411 into the inner cavity of the spray wall 413 and sprays out from the spray holes 414, the reaction force generated by the water jet acts on the wall surface of the spray holes 414 to form a tangential moment. This moment drives the spray wall 413 to continuously rotate around the axis of the water inlet pipe 411 by overcoming the bearing friction resistance, thereby realizing dynamic spraying. In this structure, the fixing nut provides axial constraint through thread locking to ensure the stable relative position between the spray wall 413 and the water inlet pipe 411; the bearing structure bears the radial load and realizes low-friction rotation, and the inclination angle design of the spray holes 414 converts the fluid kinetic energy into rotational mechanical energy. The three work together to achieve the automatic rotating spraying function without an additional power source.

[0043] In a specific embodiment, the cooking appliance assembly 3 includes at least one burner 31 and a driving module 32. The driving module 32 connects the burner 31 and the smoke collecting hood 2 and is used to drive the burner 31 to switch between a closed state and an unfolded state.

[0044] The main body of the driving module 32 is fixed to the bottom of the smoke collecting hood 2, and its power output end is directly connected to the support frame of the burner 31 through a rigid transmission rod; each burner 31 corresponds to an independent execution unit of the driving module 32. The output end of the driving module 32 is located at the upper part of the back surface of the burner 31, and the burner 31 is suspended below the smoke collecting hood 2, forming a transmission linkage structure in the vertical direction. The burner 31 serves as a cooking function unit to provide a heat source to support the user for heating operations; the driving module 32 serves as a power execution unit, outputs mechanical displacement by receiving a control signal, and drives the burner 31 to rotate to realize the switching between the closed state and the unfolded state.

[0045] When the cooking appliance assembly 3 includes two burners 31, each burner 31 is configured with an independent driving module 32. The two sets of driving modules 32 are symmetrically installed on both sides of the bottom of the smoke collecting hood 2, and the two sets of driving modules 32 are independent of each other and can respectively control the corresponding burners 31.

[0046] When it is necessary to switch to the closed state, the driving module 32 drives the burner 31 to rotate along the first direction until the smoke inlet passage 21 of the smoke collecting hood 2 is completely covered; when it is necessary to switch to the unfolded state, the driving module 32 drives the burner 31 to rotate along the second direction to completely expose the smoke inlet passage 21.

[0047] In a specific embodiment, the driving module 32 includes a rotating motor, and the rotating motor can drive the cooking hob 31 to be opened to the air-drying angle; wherein, the air-drying angle is greater than 0° and less than the angle in the unfolded state.

[0048] After the surface of the cooking hob 31 is cleaned by spraying, if it is directly closed, water accumulation may occur due to insufficient ventilation, leading to the growth of bacteria or rust; the air-drying angle forms an inclined gap between the cooking hob 31 and the smoke collecting hood 2, which not only promotes air convection to accelerate water evaporation but also avoids completely unfolding and occupying kitchen space, taking into account both hygiene and space efficiency. After the rotating motor drives the cooking hob 31 to rotate to the air-drying angle, it can be fixed by the electromagnetic self-locking function of the motor itself or the mechanical self-locking characteristic of the built-in worm and worm gear transmission mechanism: when the rotating motor stops power supply, the high friction angle design of the worm and worm gear can prevent reverse rotation; or the static magnetic field generated by the energization of the motor winding adsorbs the rotor, and the cooking hob 31 can be maintained stationary at the air-drying angle without an additional locking device.

[0049] In a specific embodiment, an installation interface 22 is provided on the smoke collecting hood 2, and the fan module 1 is detachably fixed above the installation interface 22 through a sealing structure; the smoke collecting hood 2 is installed between the kitchen wall cabinets 5.

[0050] In this embodiment, an installation interface 22 is opened at the top of the smoke collecting hood 2 as a docking plane, and a sealing structure (such as an annular sealing ring) is embedded in the periphery of the installation interface 22; the bottom flange of the fan module 1 is locked with the fixing holes outside the installation interface 22 through bolts, so that the bottom of the fan module 1 presses the sealing structure and completely covers the installation interface 22, forming a vertically detachable sealed connection, and at the same time ensuring that the air inlet of the fan module 1 is axially communicated with the smoke inlet channel 21 of the smoke collecting hood 2.

[0051] The sealing structure in this embodiment ensures zero oil fume leakage; the detachable connection enables the fan module 1 to be independently disassembled and assembled. During maintenance, it is not necessary to disassemble the smoke collecting hood 2 and the cooking appliance assembly 3, avoiding the drawback of overall removal required for maintenance in the traditional integrated design, significantly reducing the maintenance cost and ensuring long-term sealing performance. Moreover, installing the smoke collecting hood 2 between the wall cabinets 5 solves the problems of space utilization rate and installation strength: the two side walls of the smoke collecting hood 2 are directly fixed on the side plates of the adjacent wall cabinets 5, using the load-bearing of the wall cabinets 5 to replace the traditional ceiling suspension structure, which not only eliminates the occupation of floor height by the top suspension but also enhances the support stability through the wall cabinets 5, avoiding the vibration hidden danger of the suspension installation and achieving zero space occupation and structure strengthening.

[0052] In a specific embodiment, the integrated range hood further includes a smoke-stove linkage control component; the smoke-stove linkage control component is configured to: in response to the cooking appliance component 3 switching from the closed state to the unfolded state, start the blower module 1; in response to the cooking appliance component 3 switching back from the unfolded state to the closed state, automatically turn off the blower module 1 or turn off the blower module 1 after a preset time.

[0053] The function of the smoke-stove linkage control component is to achieve intelligent coordination of the motion states of the blower module 1 and the cooking appliance component 3: when the cooking appliance component 3 switches from the closed state to the unfolded state (i.e., enters the cooking position), the linkage component immediately starts the blower module 1 for oil fume suction; when the cooking appliance component 3 switches back from the unfolded state to the closed state (i.e., finishes cooking), the linkage component automatically turns off the blower module 1 or turns it off after a preset delay to remove residual oil fume; throughout the process, there is no need for manual operation of the blower switch, ensuring that the oil fume exhaust and cooking actions are always synchronized and avoiding energy waste.

[0054] In a specific embodiment, the self-cleaning component 4 further includes a drying control component. After the self-cleaning component 4 completes the cleaning operation, the drying control component can control the blower module 1 to start and control the cooking appliance component 3 to open to the drying angle to introduce air.

[0055] The function of the drying control component is to automatically process the residual moisture after cleaning: when the self-cleaning component ④ finishes the spray cleaning, this component can transmit a signal to the controller, and the controller immediately triggers the blower module 1 to start sucking air flow. At the same time, it controls the drive module 32 to rotate the cooking appliance component 3 to a specific drying angle (greater than 0° and less than the unfolding angle), so that an inclined ventilation gap is formed between the burner head 31 and the smoke collecting hood 2; external air is sucked into the hood by the negative pressure of the blower, flowing at high speed over the surface of the wet burner head 31 and the inner wall of the smoke collecting hood 2, accelerating the evaporation of moisture and completely eliminating the hidden dangers of bacterial growth and metal corrosion caused by a humid environment.

[0056] In a specific embodiment, a drain port 23 is provided at the bottom of the smoke collecting hood 2; the drain port 23 is connected to the sewer for discharging the sewage generated during the cleaning process.

[0057] The function of the drain port 23 is to achieve automatic discharge of the cleaning wastewater: this interface is opened at the lowest point of the bottom of the smoke collecting hood 2 and is directly connected to the kitchen sewer through a pipe; the oil and water mixture generated by the spray of the self-cleaning component 4 gathers at the drain port 23 under the action of gravity and is discharged into the sewer system through the pipe, completely avoiding secondary pollution and odor generation caused by sewage retention and ensuring that the cleaning process is fully automated.

[0058] Moreover, the drain outlet 23 continuously plays a guiding role in the non-cleaning state: during cooking, the condensed oil droplets dripping from the smoke inlet channel 21 or the accidentally spilled liquid oil stains naturally flow under the action of gravity to the drain outlet 23 at the lowest point of the bottom of the smoke collecting hood 2, and can be discharged into the sewer in real time without starting the self-cleaning component 4, fundamentally eliminating the problems of oil spillage, adhesion and accumulation, and bacterial growth caused by the traditional oil collecting box due to untimely cleaning.

[0059] The working process of the integrated stove provided in this embodiment starts with the unfolding of the stove component 3: when the user starts cooking, the driving module 32 drives the stove head 31 to rotate to the unfolded state, completely exposing the smoke inlet channel 21 of the smoke collecting hood 2; the smoke-stove linkage control component synchronously triggers the fan module 1 to start, sucking the cooking fumes, and the fumes enter the smoke collecting hood 2 through the smoke inlet channel 21 and are discharged outdoors by the fan module 1. The liquid oil stains dripping during cooking flow into the sewer through the drain outlet 23 at the bottom of the smoke collecting hood 2 in real time, avoiding the accumulation of oil stains. After cooking, the driving module 32 rotates the stove head 31 to the closed state, completely covering the smoke inlet channel 21; the smoke-stove linkage control component closes the fan module 1 or delays closing to remove the remaining fumes. When starting self-cleaning, the water inlet interface 43 of the self-cleaning component 4 is connected to the water source, and the water flow successively passes through the heating module 45 and the pressurizing module 42, and then is conveyed to the spraying module 41 through the connecting water pipe 44; the water inlet pipe 411 of the spraying module 41 introduces the high-temperature and high-pressure water flow into the spraying wall 413, and the water flow sprays out tangentially from a plurality of spray holes 414, and the reaction force drives the spraying wall 413 to rotate around the axis of the water inlet pipe 411 through the rotating support 412, realizing the dynamic flushing of the surface of the stove head 31 in the closed state and the inner wall of the smoke collecting hood 2; the oil stain mixture is discharged into the sewer through the drain outlet 23. After cleaning, the air drying control component starts: the driving module 32 rotates the stove head 31 to the air drying angle, forming an inclined ventilation gap; at the same time, triggering the fan module 1 to operate, and the inhaled air flows through the wet surface at high speed to accelerate the evaporation of water. Finally, the stove head 31 returns to the closed state, completing the full-cycle work.
