Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to an integrated stove and a steam exhaust structure thereof. Background Art

[0002] In a stove-steaming and baking machine, the oven cavity is located below the stove module. There is a set of steam exhaust channels between the oven and the stove module for exhausting steam during the cooking process. The steam is discharged through the top of the stove panel and drawn away by the range hood, thereby improving the problem of steam blowing in the face. However, currently the exhaust channels of the oven and the stove are mostly natural exhaust. During operation, due to the low steam pressure, the steam cannot be discharged linearly, but starts to spread from the outlet of the stove panel. Part of it will contact the cupboard to produce condensation water, which will cause the back wall of the cupboard to be damp and moldy, and even damage the material of the cupboard. Utility Model Content

[0003] The present application provides an integrated stove and a steam discharge structure thereof, which can accelerate the flow of steam at the steam outlet, thereby preventing condensation formed after the steam contacts the cabinet from causing the back wall to become damp and moldy, or even damaging the material of the cabinet.

[0004] The embodiment of the present application provides a steam exhaust structure, comprising:

[0005] A steam outlet pipe is formed with a steam outlet;

[0006] At least one air outlet pipe, the air outlet pipe is formed with an air outlet, the air outlet is arranged adjacent to the steam outlet or the air outlet pipe is sleeved outside the steam outlet pipe; and

[0007] The fan assembly is connected to the air outlet pipe and is used to supply air to the air outlet pipe. The airflow blown out through the air outlet is used to drive the steam in the steam outlet pipe to flow out from the steam outlet at an accelerated speed.

[0008] Based on the above embodiment, air is supplied to the air outlet pipe through the fan assembly, so that the airflow blown out through the air outlet is used to drive the steam in the steam outlet pipe to flow out from the steam outlet at an accelerated speed, thereby preventing the steam dissipated from the steam outlet to the surroundings from forming condensation water after contacting the cabinet, causing the back wall of the cabinet to be damp and moldy, or even damaging the material of the cabinet.

[0009] Furthermore, the velocity of the air flow blown out of the air outlet is greater than the velocity of the steam flowing out of the steam outlet.

[0010] Based on the above embodiment, the steam discharged through the steam outlet can be adsorbed into the fast airflow discharged from the air outlet and flow along with the fast airflow, thereby accelerating the flow speed of the steam.

[0011] Furthermore, the outlet direction of the air outlet is parallel to the outlet direction of the steam outlet.

[0012] Based on the above embodiments, the airflow blown out from the air outlet can directly and effectively act on the steam at the steam outlet, forming a clear airflow guide, which enables the steam to flow out more concentratedly and orderly, reduces the diffusion and escape of the steam, and improves the directionality and efficiency of steam emission.

[0013] Furthermore, the area of ​​the air outlet is smaller than the area of ​​the steam outlet.

[0014] Based on the above embodiment, a smaller air outlet area means that the wind force is more concentrated, and the air can be blown toward the air outlet at a higher speed and with a stronger pressure, and the air flow velocity is greatly improved, thereby driving the steam to flow upward more quickly.

[0015] Furthermore, the plane where the air outlet is located is coplanar with the plane where the steam outlet is located.

[0016] Based on the above embodiment, the airflow adsorption effect of the airflow blown out of the air outlet on the steam flowing out of the steam outlet is enhanced, which can better prevent the steam from scattering on the cabinet and effectively accelerate the discharge of steam.

[0017] Furthermore, the steam exhaust structure includes a plurality of the air outlet pipes, and the plurality of the air outlet pipes are distributed in a ring shape around the axis of the steam outlet pipe.

[0018] Based on the above embodiment, the wind force generated by the fan assembly can act evenly around the steam outlet pipe. This evenly distributed wind force helps to achieve all-round adsorption of the steam generated by the steam outlet, thereby preventing some steam from escaping from the edge of the steam outlet far away from the outlet pipe. In addition, the provision of multiple outlet pipes makes the steam discharge more uniform and rapid, and also helps to reduce the noise and heat generated by the device during operation, thereby improving the user experience.

[0019] Furthermore, the air outlet pipe comprises:

[0020] A first air outlet pipe is arranged in a horizontal direction, one end of which is connected to the fan assembly; and

[0021] The second air outlet pipe is arranged vertically, one end of which is connected with the other end of the first air outlet pipe, and the other end forms the air outlet.

[0022] Based on the above embodiment, through the combined design of horizontal and vertical, the air outlet duct can better adapt to different spatial layout requirements. The horizontal first air outlet duct can be conveniently connected to the fan assembly, and the vertical second air outlet duct can adjust the height and position according to actual needs, thereby optimizing the spatial layout of the entire steam exhaust structure. At the same time, the vertical second air outlet duct can make better use of the space and discharge the air directly to a high place, thereby improving the exhaust efficiency.

[0023] Furthermore, the fan assembly includes a fan, and the fan is used to supply air to at least one of the air outlet pipes.

[0024] Based on the above embodiment, the single fan design makes the entire steam exhaust structure more concise, reduces the number and complexity of components, and facilitates the optimized distribution of space within the stove.

[0025] Furthermore, the fan assembly includes a plurality of fans, and the plurality of fans are connected to the plurality of air outlet pipes in a one-to-one correspondence, and each of the fans is used to supply air to the correspondingly connected air outlet pipe.

[0026] Based on the above embodiments, each fan can be controlled independently, so the air volume can be accurately adjusted according to the requirements of different air outlet ducts to meet the ventilation requirements of different areas. Secondly, if a fan fails, other fans can still continue to work to ensure the continuity and stability of the steam exhaust structure.

[0027] Furthermore, the steam exhaust structure also includes:

[0028] A steam exhaust box body defines a steam exhaust cavity, wherein the steam exhaust cavity is formed with a steam exhaust port on an upper surface of the steam exhaust box body; and

[0029] A shielding member connected to the exhaust box body and partially shielding the exhaust port;

[0030] Wherein, the steam outlet pipe is arranged in the exhaust chamber, and the steam outlet is arranged opposite to the shielding member.

[0031] Based on the above embodiment, the steam passing through the steam outlet pipe will be blocked by the shielding member, which can avoid direct steam injection, thereby improving safety. On the other hand, it can also prevent foreign matter from falling directly into the steam outlet pipe through the steam outlet of the steam outlet pipe, thereby avoiding foreign matter blocking the flow of steam, resulting in the inability to discharge steam normally.

[0032] Furthermore, the air outlet pipe is at least partially disposed in the exhaust cavity, and the air outlet is disposed opposite to a portion of the exhaust port that is not blocked by the blocking member.

[0033] Based on the above embodiments, the airflow generated by the fan assembly can be blown directly to the exhaust port through the air outlet, so that the airflow and steam generated by the fan assembly can flow quickly to the exhaust system on the top of the integrated stove. This direct airflow path reduces the loss and diffusion of wind power and ensures the maximum effectiveness of the wind power.

[0034] A second aspect of the present application provides an integrated stove, comprising:

[0035] The steam exhaust structure as described in any one of the above items;

[0036] A stove, wherein the steam exhaust structure is disposed in the stove; and

[0037] The steam oven is located below the stove, and comprises a box body and an inner pot located in the box body, and the steam outlet pipe is connected to the inner pot.

[0038] Based on the integrated stove of the embodiment of the present application, air is supplied to the air outlet pipe through the fan assembly, so that the airflow blown out through the air outlet is used to drive the steam in the steam outlet pipe to flow out faster from the steam outlet, thereby preventing the steam dissipating from the steam outlet to the surroundings from forming condensation water after contacting the cabinet, causing the back wall of the cabinet to be damp and moldy, and even damaging the material of the cabinet.

[0039] The integrated stove and its steam discharge structure provided in the embodiment of the present application are such that an air outlet duct is sleeved on the steam outlet pipe, or the steam outlet of the steam outlet pipe is adjacent to the air outlet of the air outlet duct, and air is supplied to the air outlet duct through a fan assembly, so that the airflow blown out through the air outlet is used to drive the steam in the steam outlet pipe to flow out faster from the steam outlet, thereby preventing the steam dissipated from the steam outlet to the surroundings from forming condensation water after contacting the cupboard, causing the back wall of the cupboard to become damp and moldy, or even damaging the material of the cupboard.

DETAILED DESCRIPTION

[0047] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] See also Figure 1-2 This embodiment provides an integrated stove. The integrated stove is a kitchen appliance that integrates multiple functions such as a range hood, a gas stove, a disinfection cabinet, and a storage cabinet. It is also called an environmentally friendly stove or an integrated environmentally friendly stove in the industry. The integrated stove has the advantages of saving space, good fume extraction effect, energy saving, low consumption, and environmental protection. In this embodiment, the integrated stove includes a steam discharge mechanism 100, a stovetop 200, and a cooking utensil. In this embodiment, the cooking utensil is an utensil that can generate steam, such as a steam oven and a microwave oven. This embodiment takes the cooking utensil as an example for exemplary description.

[0049] The surface of the stove 200 is equipped with a gas stove, which can be used for various cooking methods such as boiling, cooking, frying, etc. It also has a multi-level fire adjustment function, which is convenient for adjusting the fire size and temperature according to cooking needs. Above the stove 200, that is, the top of the integrated stove, a powerful exhaust system and filtering device are configured, which can effectively absorb, filter and purify the generated oil smoke, smoke and odor. Through efficient filtering equipment, most harmful substances can be filtered out, reducing pollution to indoor air and ensuring the cleanliness and hygiene of the kitchen environment.

[0050] The steam oven is located below the stove 200. The steam oven includes a box body and an inner tank located in the box body. The inner tank has a steaming and baking cavity. Food that needs to be steamed and baked can be placed in the steaming and baking cavity, which can realize cooking methods such as quick steaming and water-replenishing steam tender baking.

[0051] The steam exhaust mechanism 100 is arranged in the stove top 200, and the steam exhaust structure 100 is connected to the inner pot in the box of the steam oven, and is used to discharge the steam in the inner pot to avoid excessive water vapor inside the inner pot, thereby ensuring the normal operation of the steam oven and the cooking quality of food. The steam exhausted by the steam exhaust structure 100 is generally absorbed and discharged by the powerful exhaust system on the top of the integrated stove.

[0052] See also Figure 1-2 In some embodiments, the steam exhaust structure 100 includes a steam outlet pipe 10, at least one air outlet pipe 20 and a fan assembly 30. The steam outlet pipe 10 is connected to the inner pot of the steam oven, one end of the steam outlet pipe 10 connected to the inner pot of the steam oven forms a steam inlet, and the other end forms a steam outlet 10a, which is used to discharge the high-temperature steam generated by the steam oven in the working state to avoid excessive water vapor in the inner pot, thereby ensuring the normal operation of the steam oven and the cooking quality of food.

[0053] The air outlet 20 is formed with an air outlet 20a, and the air outlet 20a is arranged adjacent to the steam outlet 10a or the air outlet 20 is sleeved outside the steam outlet 10. It should be noted that the air outlet 20a of the air outlet 20 is arranged adjacent to the steam outlet 10a, which means that the distance between the air outlet 20a and the steam outlet 10a is less than the first preset value, so that the airflow blown out through the air outlet 20a can drive the steam to flow out from the steam outlet 10a faster. Among them, the first preset value can be flexibly selected in combination with actual needs, and is not limited to this.

[0054] The fan assembly 30 is connected to the air outlet pipe 20 to supply air to the air outlet pipe 20. The airflow blown out through the air outlet 20a is used to drive the steam in the steam outlet pipe 10 to flow out from the steam outlet 10a at an accelerated speed. The fan assembly 30 is the power source of the entire steam discharge structure. It is connected to the air outlet pipe 20 to provide stable wind force for the air outlet pipe 20. The operation of the fan assembly 30 enables the air outlet 20a to blow out airflow continuously and stably, ensuring the continuity and stability of steam discharge.

[0055] In the related art, during the steam discharge process of the steam oven, due to the natural exhaust, the steam pressure is low, resulting in the steam not being discharged linearly, but starting to spread out from the outlet of the cooker panel, part of which is absorbed and discharged by the powerful exhaust system on the top of the integrated stove, and part of which contacts the cabinet to produce condensed water, which can cause the back wall of the cabinet to be damp and moldy, and even damage the material of the cabinet. In the embodiment of the present application, an air outlet duct 20 having an air outlet 20a is provided, and the air outlet 20a is adjacent to the steam outlet 10 of the steam outlet duct 10, or the air outlet duct 20 is sleeved outside the steam outlet duct 10, and A fan assembly 30 connected to the air outlet duct 20 is provided to supply air to the air outlet duct 20. Compared with the case where the fan assembly 30 and the air outlet duct 20 are not provided, the air flow velocity at the air outlet 20a can be accelerated. The accelerated air flow velocity at the air outlet 20a is beneficial to accelerate the flow of the steam airflow discharged through the steam outlet 10a, so that the steam is quickly discharged upward with the faster air flow and is absorbed by the powerful exhaust system at the top. In this way, the steam will not disperse to the surroundings, nor will it contact the cabinet to produce condensation water, thereby preventing the back wall of the cabinet from being damp and moldy and damaging the material of the cabinet.

[0056] In some embodiments, the air flow rate blown out of the air outlet 20a is greater than the steam flow rate of the steam outlet 10a, so that the steam discharged through the steam outlet 10a can be absorbed into the fast airflow discharged from the air outlet 20a and flow with the fast airflow.

[0057] In some embodiments, the outlet direction of the air outlet 20a is parallel to the outlet direction of the steam outlet 10a, wherein the outlet direction of the air outlet 20a refers to being perpendicular to the plane where the air outlet 20a is located and along the direction of airflow outflow, while the outlet direction of the steam outlet 10a refers to being perpendicular to the plane where the air outlet 20a is located and along the direction of steam outflow. In this way, the air outlet 1 can be set at any position adjacent to the steam outlet 10a, and the air outlet 1 is located at different positions of the stove 200. There will be no significant difference in the accelerated discharge of steam, and the flexibility of arranging the steam discharge structure 100 on the stove 200 can also be improved.

[0058] In addition, since the outlet direction of the air outlet 20a is parallel to the outlet direction of the steam outlet 10a, the airflow blown out from the air outlet 20a can directly and effectively act on the steam at the steam outlet 10a, forming a clear airflow guide. This allows the steam to flow out more concentratedly and orderly, reduces the diffusion and escape of steam, and improves the directionality and efficiency of steam discharge. In addition, the parallel axis allows the wind force generated by the fan assembly 30 to be converted into power to promote the flow of steam to the greatest extent, reducing energy loss in the conversion process. This helps to improve the energy efficiency of the entire steam discharge structure and reduce energy consumption.

[0059] Furthermore, the steam outlet pipe 10 can be parallel to the air outlet pipe 20, so that the steam outlet pipe 10 is parallel to the axis of the air outlet pipe 20. In this way, the airflow blown out by the fan assembly 30 through the air outlet pipe 20 has low energy loss and can still maintain a high flow rate, which can drive the steam in the steam outlet pipe 10 to flow out from the steam outlet 10a faster.

[0060] In addition, the steam outlet pipe 10 and the air outlet pipe 20 are arranged in parallel, which can reduce the total volume of the steam exhaust structure 100, thereby releasing more space for other structures or operations.

[0061] In the above embodiment, when the air outlet pipe 20 is arranged outside the steam outlet pipe 10, the structure of the entire system is more compact, the occupied space is reduced, and it is beneficial to the spatial layout inside the stove 200. The axis of the air outlet 20a and the axis of the steam outlet 10a can be parallel or collinear, both of which can play a role in accelerating the flow of steam. However, it should be understood that when the axis of the air outlet 20a and the axis of the steam outlet 10a are collinear, the airflow directions of the steam and the air are consistent, which helps to form a more uniform and stable airflow distribution.

[0062] Specifically, the area of ​​the air outlet 20a is smaller than the area of ​​the steam outlet 10a. The steam outlet 10a may be circular, elliptical, rectangular, triangular, rhombus, etc. If the air outlet 20a is arranged adjacent to the steam outlet 10a, the area of ​​the air outlet 20a is the area surrounded by the inner edge of the end of the air outlet pipe 20, and the steam outlet 10a is the area surrounded by the inner edge of the end of the steam outlet pipe 10 forming the steam outlet 10a. The air outlet 20a may be circular, elliptical, rectangular, triangular, rhombus, etc. In this embodiment, the steam outlet 10a and the air outlet 20a are preferably circular, and the circular air outlet makes the air flow smoother, thereby improving the air flow efficiency. If the air outlet pipe 20 is arranged outside the steam outlet pipe 10, the area of ​​the air outlet 20a is the area of ​​the region between the inner edge of the end of the air outlet pipe 20 and the outer edge of the end of the steam outlet pipe 10 forming the steam outlet 10a. The air outlet 20a can be a circular ring, an elliptical ring, a rectangular ring, a triangular ring, a diamond ring, etc., preferably a circular ring, which can ensure that the air volume at each part of the air outlet 20a is roughly the same, so that the airflow can be blown to the powerful exhaust system above the stove 200. In addition, due to the smooth curve of the circular ring, the air flows more smoothly when passing through the air outlet 20a, reducing the generation of turbulence and vortices, thereby reducing noise.

[0063] It is understandable that a smaller area of ​​the air outlet 20a means that the wind is more concentrated. When the fan assembly 30 is started, at the same power, it can blow air to the air outlet 20a at a higher speed and a stronger pressure, and the air flow rate is greatly improved, thereby driving the steam to flow upward more quickly. On the other hand, a smaller area of ​​the air outlet 20a helps to reduce the diffusion and escape of wind, so that more wind can directly act on the steam instead of being wasted in the surrounding environment, which helps to improve the efficiency of energy utilization and reduce overall energy consumption.

[0064] In some embodiments, the plane where the air outlet 20a is located is coplanar with the plane where the steam outlet 10a is located. Preferably, the plane where the air outlet 20a is located and the plane where the steam outlet 10a is located are parallel to the table top of the stove 200, which looks neater and more elegant in appearance.

[0065] If the plane where the air outlet 20a is located is higher or lower than the steam outlet 10a, there is a certain distance between the air outlet 20a and the steam outlet 10a in the height direction, which may cause a small amount of steam to be scattered onto the cupboard during the transmission process, causing the back wall of the cupboard to be damp and moldy, and even damaging the material of the cupboard. When the air outlet 20a and the steam outlet 10a are located on the same plane, the distance between them is smaller, which enhances the airflow adsorption effect of the airflow blown out of the air outlet 20a on the steam flowing out of the steam outlet 10a, can better prevent the steam from being scattered onto the cupboard, and effectively accelerate the discharge of steam.

[0066] In the embodiment of the present application, multiple or one air outlet duct 20 may be provided. If there is one air outlet duct 20, the air outlet duct 20 may be sleeved outside the steam outlet duct 10 or the air outlet 20a may be arranged adjacent to the steam outlet 10a. Designing one air outlet duct 20 is conducive to simplifying the structure of the steam exhaust structure 100. If there are multiple air outlet ducts 20, multiple air outlet ducts 20 may be sleeved outside the steam outlet duct 10 in sequence from the inside to the outside or multiple air outlet ducts 20 may be arranged adjacent to the steam outlet 10a. Multiple air outlet ducts 20 may be designed to discharge air at the same time or partially, so that the air outlet volume of the light outlet duct 20 may be selectively adjusted according to the steam discharge volume, thereby improving the steam discharge efficiency. In the embodiment of the present application, the orientation and number of the air outlet duct 20 may be designed in combination with the space margin in the stove 200 and the steam discharge volume at the steam outlet 10a, etc., and there is no limitation on this.

[0067] If the steam discharge structure 100 includes a plurality of air outlet pipes 20, the plurality of air outlet pipes 20 are distributed in a ring shape around the axis of the steam outlet pipe 10. Through the ring shape distribution of the plurality of air outlet pipes 20, the wind force generated by the fan assembly 30 can evenly act around the steam outlet pipe 10. This evenly distributed wind force helps to achieve the omnidirectional adsorption of the steam generated by the steam outlet 10a, thereby preventing part of the steam from escaping from the edge of the steam outlet 10a away from the air outlet pipe 20. In addition, the provision of the plurality of air outlet pipes 20 makes the steam discharge more even and fast, and also helps to reduce the noise and heat generated during the operation of the device, thereby improving the user experience.

[0068] Please continue reading Figure 1-2 The air outlet duct 20 includes a first air outlet duct 21 and a second air outlet duct 22. The first air outlet duct 21 is arranged in a horizontal direction, and one end of the first air outlet duct 21 is connected to the fan assembly 30. The second air outlet duct 22 is arranged in a vertical direction, and one end of the second air outlet duct 22 is connected to the other end of the first air outlet duct 21, and the other end forms an air outlet 20a. The first air outlet duct 21 can be located at any position in the stove 200 without specific limitation, and can be flexibly designed according to the actual internal space of the stove 200.

[0069] Through the combined design of horizontal and vertical, the air outlet pipe 20 can better adapt to different spatial layout requirements. The horizontal first air outlet pipe 21 can be conveniently connected to the fan assembly 30, and the vertical second air outlet pipe 22 can adjust the height and position according to actual needs, thereby optimizing the spatial layout of the entire steam exhaust structure 100. At the same time, the vertical second air outlet pipe 22 can make better use of the space and discharge the air directly to a high place, thereby improving the exhaust efficiency.

[0070] The first air outlet pipe 21 and the second air outlet pipe 22 can be welded together or connected together by flanges. The specific design is based on the actual situation. It can be understood that in order to reduce the flow resistance of the air, the connection between the first air outlet pipe 21 and the second air outlet pipe 22 is made into an arc transition. For example, the first air outlet pipe 21 and the second air outlet pipe 22 can be connected by setting an arc pipe, so that the airflow can be smoothly guided from the first air outlet pipe 21 to the second air outlet pipe 22, avoiding the airflow turbulence and increased resistance that may be caused by right-angle or other acute-angle connections, which helps to improve the ventilation efficiency of the entire air outlet pipe 20. In addition, the arc transition design helps to reduce the noise level by reducing the resistance of the airflow in the transition area, making the air outlet pipe 20 quieter during operation.

[0071] In some embodiments, please refer to Figure 1Regardless of whether the steam exhaust structure 100 includes one air outlet pipe 20 or multiple air outlet pipes 20, the fan assembly 30 includes a fan, which is used to supply air to at least one air outlet pipe 20. The single fan design makes the entire steam exhaust structure 100 more concise, reduces the number of components and complexity, and facilitates the optimization of the space distribution in the stove 200. The position of the fan is designed according to the space distribution in the stove 200. It can be understood that when the position of the air outlet 20a is determined, the closer the fan is to the air outlet 20a, that is, the shorter the length of the air outlet pipe 20, the shorter the air outlet pipe 20 means that the distance the air flows in the pipe is reduced, and the resistance of the air in the pipe will also be reduced, so the energy loss is also reduced accordingly, so that a greater wind speed and wind force can be maintained, and the flow of steam can be better accelerated. At the same time, only one fan needs to be controlled, making the operation and control of the system simpler and more direct.

[0072] In some other embodiments, if the steam exhaust structure 100 includes multiple air outlet pipes 20, the fan assembly 30 includes multiple fans, the multiple fans are connected to the multiple air outlet pipes 20 one by one, and each fan is used to supply air to the correspondingly connected air outlet pipe 20, the multiple air outlet pipes 20 can be distributed in a ring shape around the axis of the steam outlet pipe 10, so that the steam exhaust is more uniform and faster.

[0073] Each fan can be controlled independently, so the air volume can be accurately adjusted according to the needs of different air outlet ducts to meet the ventilation requirements of different areas. Secondly, if a fan fails, other fans can still continue to work to ensure the continuity and stability of the steam exhaust structure 100.

[0074] See also Figure 3-5 The steam exhaust structure 100 also includes a steam exhaust box body 40 and a shielding member 50 .

[0075] The exhaust box body 40 is located on the stove 200 and defines an exhaust cavity 40a. The exhaust cavity 40a is formed with an exhaust port 40b on the upper surface of the exhaust box body 40. The exhaust port 40b should not be protruding from the upper surface of the stove 200. In this way, the upper surface of the stove 200 is a whole plane, which looks neat, generous and beautiful. The side wall of the exhaust box body 40 is provided with a vent hole connected to the stove 200, which can dissipate the heat in the stove 200 in time, maintain the stable operation of the integrated stove, and prevent safety problems caused by overheating. In addition, when the flame heats the food, the carbon dioxide produced needs to combine with a certain amount of oxygen to be completely burned. The vent hole allows an appropriate amount of oxygen to enter the combustion area, thereby ensuring that the flame burns more stably and improving the cooking effect.

[0076] The shielding member 50 is connected to the exhaust box body 40 and partially blocks the exhaust port 40b. For the sake of aesthetics, the shielding member 50 and the exhaust box body 40 are an integrally formed structure, wherein the steam outlet pipe 10 is inserted into the exhaust cavity 40a, and the steam discharged from the steam outlet of the steam outlet pipe 10 first enters the exhaust cavity 40a, and then is discharged to the outside of the stove 200 through the exhaust port 40b at the upper end. The steam outlet 10a of the steam outlet pipe 10 is arranged opposite to the shielding member 50, so that the steam passing through the steam outlet pipe 10 will be blocked by the shielding member 50, which can avoid direct steam injection, thereby improving safety. On the other hand, it can also prevent foreign matter from falling directly into the steam outlet pipe 10 through the steam outlet 10a of the steam outlet pipe 10, so as to avoid foreign matter blocking the flow of steam, resulting in the inability to discharge steam normally.

[0077] In addition, since the steam outlet 10a is located in the exhaust cavity 40a, and the shielding member 50 is connected to the exhaust box body 40, partially shields the exhaust port 40b, and is arranged opposite to the steam outlet 10a, the steam passing through the steam outlet 10a is shielded by the exhaust box body 40 and the shielding member 50, so that the steam enters the exhaust cavity 40a more concentratedly. This guiding effect helps to reduce the diffusion and escape of the steam, and will not diffuse out of the exhaust cavity 40a in the first time, improve the gathering effect of the steam in the exhaust cavity 40a, and help the airflow blown out through the air outlet 20a to more completely accelerate the steam to flow out of the steam outlet 10a.

[0078] It can be understood that in order to enable the steam discharged from the steam outlet pipe 10 to be quickly absorbed by the exhaust system on the top of the integrated stove, the steam exhaust box 40 is designed to be located on the stove top 200 close to the air outlet of the exhaust system. In this way, the exhaust system can absorb the steam in time to prevent steam from hurting people.

[0079] Please continue reading Figure 5 The air outlet pipe 20 is at least partially arranged in the exhaust cavity 40a, and the air outlet 20a is arranged opposite to the portion of the exhaust port 40b that is not blocked by the shielding member 50. In this way, the airflow generated by the fan assembly 30 can be directly blown to the exhaust port 40b through the air outlet 20a, so that the airflow and steam generated by the fan assembly 30 can quickly flow to the exhaust system on the top of the integrated stove. This direct airflow path reduces the loss and diffusion of wind force, ensuring the maximum effectiveness of the wind force.

[0080] In some embodiments, the air outlet duct 20 can be completely disposed in the exhaust cavity 40a, that is, the fan assembly 30 can be disposed in the exhaust cavity 40a, or on the outer side wall of the exhaust box body 40, so that material costs can be saved and the space of the stove 200 occupied by the air outlet duct 20 can be reduced. If the fan assembly 30 is disposed in the exhaust cavity 40a, the internal space of the exhaust box body 40 can be utilized to the maximum extent, the volume of the overall device can be reduced, and the design can be more compact. If the fan assembly 30 is disposed outside the exhaust cavity 40a, that is, disposed on the outer side wall of the exhaust box body 40, the fan assembly 30 can be maintained and repaired more easily.

[0081] In some other embodiments, the air outlet duct 20 can be partially disposed in the exhaust chamber 40a, that is, the air outlet duct 20 is passed through the exhaust chamber 40a, and the fan assembly 30 is located outside the exhaust chamber 40a. The steam exhaust structure 100 occupies the space inside and outside the exhaust chamber 40a, that is, it has a larger space during installation, which is convenient for installation, replacement and maintenance.
