These drawings and written descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0056] As mentioned in the background, the air outlet in the prior art does not have a specific setting position in the air outlet shell, and the airflow will be offset or unevenly distributed in the air cavity. This unevenness will cause the wind speed in some areas to be higher, and the wind speed in other areas to be lower, thereby affecting the overall air outlet uniformity.

[0057] Therefore, in the embodiments of the present application, the air inlet is arranged in the middle of the air cavity, so that the airflow can be more evenly distributed in the entire air cavity, thereby improving the uniformity of the air outlet. By optimizing the orientation of the air outlet and the orientation of the air inlet, direct collision of the airflow is avoided, turbulence and interference of the airflow are reduced, the airflow path is optimized, the airflow can flow more smoothly, and the air outlet effect of the fresh air module is better. Therefore, through reasonable structural design, the airflow can be fully diffused and evenly distributed in the air cavity, thereby enhancing the air outlet effect of the fresh air module.

[0058] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements throughout the several drawings. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present application. Rather, it is merely an example of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0059] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0060] With reference to Figures 1-2 , the present application provides a kitchen air conditioner,

[0061] The kitchen air conditioner comprises a shell 400 and a fresh air module;

[0062] The fresh air module comprises a fan 100, an air outlet shell 200 and an air guide duct 300;

[0063] The fan 100 is arranged in the shell 400;

[0064] The air outlet shell 200 is arranged in the shell 400, and the air outlet shell 200 is provided with an air cavity 201 extending in a first direction. The air outlet shell 200 is provided with an air inlet 210 and an air outlet 220 extending in the first direction;

[0065] The air inlet end of the air guide duct 300 is communicated with the fan 100, the air outlet end of the air guide duct 300 is communicated with the air inlet 210 of the middle part of the air cavity 201 in the first direction, and the air outlet end of the air guide duct 300 is not opposite to the air outlet 220.

[0066] It should be noted that the first direction refers to the width direction of the air outlet shell 200, that is, the left-right direction parallel to the wall when the equipment is installed on the wall.

[0067] It can be known that the air inlet end of the air guide pipe 300 is in communication with the fan 100, and such a design ensures that the airflow generated by the fan 100 can effectively enter the air guide pipe 300; the air outlet shell 200 is provided with an air cavity 201 extending along the first direction, and such a design of the air cavity 201 helps to guide the flow of the airflow in the air outlet shell 200; the air inlet 210 is in communication with the middle part of the air cavity 201 along the first direction, which means that the airflow enters the air cavity 201 from the middle position, so that the airflow can be evenly diffused in both end directions of the first direction starting from the air inlet 210, instead of being concentrated on one side. Such a symmetrical airflow distribution helps to reduce the phenomenon of local airflow being too strong or too weak; the air outlet 220 extends along the first direction, and its orientation is not opposite to that of the air inlet 210, which means that the airflow will not directly collide. Such a design reduces the turbulence and turbulence of the airflow in the air cavity 201, so that the airflow can flow more smoothly.

[0068] By arranging the air inlet 210 in the middle of the air cavity 201, the airflow can be more evenly distributed in the entire air cavity 201, thereby improving the uniformity of the air outlet; by optimizing the orientation of the air outlet 220 and the orientation of the air inlet 210, direct collision of the airflow is avoided, turbulence and interference of the airflow are reduced, the airflow path is optimized, the airflow can flow more smoothly, and the air outlet effect of the fresh air module is better; therefore, through reasonable structural design, the airflow can be fully diffused and evenly distributed in the air cavity 201, thereby enhancing the air outlet effect of the fresh air module, and a more effective air curtain can be formed to block the oil fume.

[0069] Reference Figure 3 In some possible implementations, the shell 400 has a cavity inside, and the cavity has an air conditioner hot cavity (not shown in the figure) and an air conditioner cold cavity 420 which are independent of each other.

[0070] The fan 100 is located in the air conditioner cold cavity 420. And / or, at least part of the air guide pipe 300 is located in the air conditioner cold cavity 420.

[0071] The air conditioner cold cavity 420 is arranged in the shell 400, and this cold cavity 420 is used to accommodate and protect key components such as the fan 100 and part of the air guide pipe 300; the fan 100 is located in the air conditioner cold cavity 420, and such an arrangement helps to keep the fan operating at a lower temperature, prolong its service life and improve its efficiency; at least part of the air guide pipe 300 is located in the air conditioner cold cavity 420, and such a design helps to pre-cool the airflow before it enters the kitchen, improves the air outlet effect, and provides a more comfortable ambient temperature.

[0072] In some possible implementations, in the first direction, the air outlet end of the fan 100 is arranged in a staggered manner with the air outlet end of the air guide pipe 300.

[0073] It can be known that the air outlet end of the fan 100 is misaligned with the air outlet end of the air guide duct 300, which means that the airflow directly blown by the fan 100 does not directly align with the air outlet end of the air guide duct, but is redistributed and guided through the design of the air guide duct 300, thereby avoiding direct and concentrated airflow impact, enhancing the uniformity of the air outlet, and helping to form a more uniform air curtain to block oil fumes; the misalignment design causes the airflow to be uniformly distributed when entering the air cavity 201, reducing the generation of vortex and turbulence, thereby improving the air outlet effect; by avoiding direct airflow impact, the noise and vibration between the fan 100 and the air guide duct 300 are reduced, improving the comfort and user experience of the kitchen air conditioner.

[0074] In some possible embodiments, the air guide duct 300 includes a first connecting section 310 and a second connecting section 320 connected in sequence; a first end of the first connecting section 310 is in communication with the air outlet end of the fan 100, and a second end of the first connecting section 310 extends downward along the height direction of the shell 400; the connecting line direction of the first end and the second end of the second connecting section 320 forms an angle with the front-rear direction of the shell 400.

[0075] And / or, the second connecting section 320 includes a plurality of extension sections 321 connected in sequence, and the extension direction of at least one extension section 321 is parallel to the first direction.

[0076] It can be known that the design of the air guide duct allows the airflow to be transported downward from the top, utilizing gravity and airflow inertia; the connecting line direction of the first end and the second end of the second connecting section 320 forms an angle with the front-rear direction of the shell 400, which means that the airflow will be deflected in direction when passing through the second connecting section 320, rather than flowing directly along the front-rear direction of the shell; the design of the extension section 321 allows the airflow to be distributed and adjusted in different directions when passing through the second connecting section.

[0077] By introducing the angle and the plurality of extension sections 321 in the second connecting section 320, the airflow is redistributed when passing through the air guide duct 300, reducing the formation of concentrated airflow and enhancing the uniformity of the air outlet; the airflow can be adjusted and distributed in different directions when passing through the plurality of extension sections 321, thereby reducing the generation of vortex and turbulence and improving the air outlet effect.

[0078] In some embodiments, the fan 100 is arranged at the top of the shell 400, and the fan is close to the rear side of the shell 400.

[0079] The first end of the second connecting section 320 is in communication with the second end of the first connecting section 310, the second end of the second connecting section 320 extends toward the front side of the shell 400, and the second end of the second connecting section 320 is in communication with the middle part of the air cavity 201.

[0080] The position of the fan 100 is selected so that the fan 100 can effectively suck in air in the kitchen and distribute it through the air guide duct 300. In some possible embodiments, the air outlet shell 200 has a first side wall 230 and a second side wall 240 connected to each other.

[0081] The air inlet 210 is arranged on the first side wall 230, and the first side wall 230 is connected to the air guide duct 300.

[0082] The air outlet 220 is arranged on the second side wall 240, and the air outlet 220 is arranged in a direction perpendicular to the air inlet 210.

[0083] It can be understood that the design of the first side wall 230 and the second side wall 240 connected to each other forms a shell structure with two main surfaces, facilitating the guidance and distribution of air flow; the design of the air inlet 210 on the first side wall 230 means that the air flow enters the air outlet shell 200 from the air guide duct 300, and enters the air cavity 201 through the air inlet 210 on the first side wall 230; the design of the air outlet 220 on the second side wall 240 means that the air flow needs to change direction after entering the air outlet shell 200, so as to be more evenly distributed inside the air outlet shell 200.

[0084] Since the air outlet 220 is arranged in a direction perpendicular to the air inlet 210, the air flow needs to change direction in the air outlet shell 200, which helps to diffuse and evenly distribute the air flow in the air outlet shell 200, reducing the phenomenon of local air flow being too strong or too weak; the perpendicular arrangement of the air inlet and the air outlet 220 avoids the direct collision of the air flow, reduces turbulence and interference of the air flow, and makes the blown air flow more stable and uniform; through reasonable structural design, the air flow can be fully diffused and evenly distributed in the air outlet shell, thereby enhancing the uniform air outlet effect of the fresh air module and forming a more effective air curtain to block the oil fume.

[0085] In some possible embodiments, the air outlet shell 200 is provided with an air guide piece 250, and the air guide piece 250 is located in the air cavity 201.

[0086] The air guide piece 250 is provided with an air guide cavity 2011, and the air guide cavity 2011 is located in the air cavity 201; the air guide cavity 2011 has a larger diameter at one end close to the air inlet 210 than at an end away from the air inlet 210.

[0087] In some possible embodiments, the air guide piece 250 gradually decreases in volume along a direction perpendicular to the first direction.

[0088] It can be known that the air guide is located in the air cavity 201, the presence of the air guide 250 helps to guide the flow of air in the air cavity 201, and the diameter of the air guide cavity 2011 near one end of the air inlet 210 is larger than that of the air guide cavity 2011 away from the air inlet 210. The design forms a gradually narrowing channel. According to the continuity equation of fluid mechanics, in a closed system, the flow rate of fluid is inversely proportional to the cross-sectional area. By gradually reducing the diameter of the air guide cavity 2011, the fluid will accelerate when passing through the air guide cavity 2011. This acceleration can help the air flow more effectively through the system, increase the air outlet speed and momentum; according to Bernoulli's principle, the static pressure of the fluid will decrease while the flow rate increases. By designing the tapered structure of the air guide cavity 2011, part of the static pressure can be converted into dynamic pressure, thereby increasing the kinetic energy of the air flow. This pressure conversion helps to improve the overall performance of the air flow; because the air guide 250 gradually reduces in volume along the first direction perpendicular to the first direction, the air guide cavity 2011 also gradually reduces in volume along the first direction perpendicular to the first direction. The tapered design of the air guide cavity 2011 provides a smooth pressure gradient change. When the air flow passes through the tapered area, the pressure gradually decreases rather than suddenly changes. This smooth transition helps to reduce flow instability. The smooth pressure change reduces the disturbance inside the fluid, reducing the intensity of turbulence. Turbulence usually causes energy loss and air flow instability, while the tapered design can make the air flow smoother and more stable, reducing energy consumption.

[0089] where, the continuity equation of fluid mechanics is as follows:

[0090] A1 x V1 = A2 x V2;

[0091] wherein A1 and A2 are the cross-sectional areas of the fluid at two different cross sections (unit: square meter, m 2 ) respectively;

[0092] V1 and V2 are the flow rates of the fluid at the two cross sections (unit: meter / second, m / s) respectively.

[0093] Bernoulli's equation describes the conversion of energy of fluid during flow. For ideal fluid (incompressible, non-viscous) along the streamline, Bernoulli's equation can be expressed as:

[0094]

[0095] wherein P is the static pressure of the fluid (unit: Pascal, Pa);

[0096] ρ is the density of the fluid (unit: kilogram / cubic meter, kg / m 3 );

[0097] v is the velocity of the fluid (unit: meter / second, m / s);

[0098] g is the acceleration of gravity (unit: m / s 2 , m / s 2 );

[0099] h is the height of the fluid (unit: m, m).

[0100] Through the gradual contraction design of the air guide cavity 2011, the airflow is accelerated and uniformly distributed when passing through the air guide cavity 2011, which helps to reduce the turbulence of the airflow and improve the uniformity of the air outlet. The structure of the air guide cavity 2011 enables the airflow to be better diffused and uniformly distributed when entering the air outlet cavity 201, thereby enhancing the air outlet effect of the fresh air module and forming a more effective air curtain to block the oil fumes. The gradually contracting air guide cavity 2011 design causes the airflow to accelerate when passing through, thereby increasing the kinetic energy of the airflow and improving the stability and effectiveness of the air curtain, thereby improving the overall performance of the kitchen air conditioner.

[0101] In some possible embodiments, the number of air guide pieces 250 is multiple, and the multiple air guide pieces 250 include a first air guide piece 251 and a second air guide piece 252.

[0102] The first air guide piece 251 is arranged between the air inlet 210 and the first end of the air cavity 201, and the second air guide piece 252 is arranged between the air inlet 210 and the second end of the air cavity 201.

[0103] It can be understood that the first air guide piece 251 is arranged between the air inlet 210 and the first end of the air cavity 201, and the air guide piece 250 at this position is mainly used to guide and distribute the airflow entering from the air inlet 210, so that the airflow uniformly flows to the first end of the air cavity 201; the second air guide piece 252 is arranged between the air inlet 210 and the second end of the air cavity 201, and the air guide piece 250 at this position is used to guide and distribute the airflow, so that the airflow uniformly flows to the second end of the air cavity 201.

[0104] By arranging the first air guide piece 251 and the second air guide piece 252 at the two ends of the air cavity 201 respectively, the airflow can be more uniformly distributed in the entire air cavity 201, reducing the phenomenon that the airflow is concentrated on one side of the air cavity 201, and improving the uniformity of the air outlet; the arrangement of multiple air guide pieces 250 helps to optimize the distribution of the airflow, so that the fresh air module can form a more stable and effective air curtain, thereby better blocking the oil fumes.

[0105] In some possible embodiments, the air outlet shell 200 is reused to form the air guide piece 250, and the inner wall of the air outlet shell 200 surrounds the air guide cavity 2011.

[0106] It can be understood that the air outlet shell 200 not only serves as a channel for the airflow, but also is reused to form the air guide piece 250, that is, the air outlet shell 200 is integrally formed with the air guide piece 250. This design cleverly utilizes the structure to reduce the complexity and number of components.

[0107] The air flow can be better guided and distributed when passing through the air guide cavity 2011 surrounded by the inner wall of the air outlet shell 200, thereby improving the uniformity of the air outlet; the air outlet shell 200 is reused to form the air guide member, reducing the need for additional air guide components, simplifying the structural design, and reducing manufacturing cost and complexity; the presence of the air guide cavity 2011 enables the air flow to be optimally distributed before entering the air outlet, enhancing the air outlet effect of the fresh air module and forming a more effective air curtain to block the oil fume.

[0108] In some embodiments, the air shell 200 and the air guide member 250 can be made of metal materials such as aluminum alloy materials. Aluminum alloy is light in weight, corrosion resistant, and easy to process and form. Stainless steel materials can also be used, which are highly corrosion resistant and strong.

[0109] The air shell 200 and the air guide member 250 can be made of plastic materials such as polypropylene (PP). Polypropylene has good chemical resistance and fatigue resistance, and is light in weight. Polycarbonate (PC) can also be used, which has high strength, impact resistance, and transparency, and is more aesthetically pleasing.

[0110] It should be noted that the air shell 200 and the air guide member 250 only need to have an air guiding effect, and the specific structure and material of the air shell 200 and the air guide member 250 are not limited in the embodiments of the present application.

[0111] Reference Figure 3 In some possible embodiments, the shell 400 is provided with a smoke suction port 410 facing the front side.

[0112] The fresh air module is arranged in the shell 400, and the air outlet 220 is arranged on the front side of the smoke suction port 410, facing the lower side of the shell 400 and the front side of the shell 400.

[0113] It can be understood that the smoke suction port 410 is designed to effectively absorb the oil fume generated during cooking; the fresh air module is arranged in the shell 400 to ensure that it is closely integrated with the overall structure, and the air outlet 220 is designed on the front side of the smoke suction port 410, which enables the fresh air module to form an air curtain in front of the smoke suction port; the position of the air outlet 220 in the shell 400 ensures that the air flow can effectively cover the area where the user is located, forming an air curtain to block the oil fume.

[0114] By setting the air outlet 220 at the front side of the smoke suction port 410 and towards the lower side and front side of the shell 400, the air curtain formed can effectively block the oil fume and prevent it from spreading to other areas of the kitchen, improving the user experience; the optimized direction of the air outlet 220 enables the fresh air module to form a continuous airflow in the user operation area, improving the air in the kitchen; the integrated design of the fresh air module and the shell 400 reduces the volume and complexity of the equipment, while ensuring the coordinated work of various functional components.

[0115] In some possible embodiments, the smoke suction port 410 extends along the width direction of the shell 400.

[0116] The first direction is parallel to the width direction of the shell 400, and the air outlet 220 is arranged in parallel and spaced apart from the smoke suction port 410.

[0117] It can be known that the smoke suction port 410 extends along the width direction of the shell 400, which ensures that the smoke suction port 410 can cover a larger area and effectively absorb the oil fume generated during cooking; the first direction is parallel to the width direction of the shell 400, which means that the main direction of the airflow is consistent with the extension direction of the smoke suction port, ensuring that the airflow can effectively cover the entire smoke suction area; the air outlet 220 is arranged in parallel and spaced apart from the smoke suction port 410, which enables the air outlet 220 to form a parallel air curtain in front of the smoke suction port 410, effectively blocking the oil fume.

[0118] The extension design of the smoke suction port 410 along the width direction enables it to cover a larger area, thereby improving the oil fume absorption efficiency; the air outlet 220 is arranged in parallel and spaced apart from the smoke suction port 410, and the air curtain formed can effectively block the oil fume and prevent it from spreading to other areas of the kitchen; the airflow direction is consistent with the extension direction of the smoke suction port 410, ensuring smooth and uniform distribution of the airflow and improving the air flow in the kitchen.

[0119] Reference Figure 3 In some possible embodiments, the shell 400 is provided with a movable baffle 500 to close or open the smoke suction port 410.

[0120] When the baffle 500 is in the open state, the first surface of the baffle 500 faces the smoke suction port 410, and the second surface of the baffle 500 faces the air outlet 220.

[0121] Alternatively, when the baffle 500 is in the open state, the air outlet 220 is located on the side of the baffle 500 close to the smoke suction port 410.

[0122] It can be known that the design of the baffle 500 allows flexible control of the opening and closing of the smoke suction port 410 to adapt to different cooking needs and environmental conditions; when the baffle 500 is in the open state, the first surface thereof faces the smoke suction port 410, and the second surface thereof faces the air outlet 220, which design makes the baffle 500 close the air outlet 220, reduces the occupied volume of the device when not working, and is more beautiful; when the baffle 500 is in the open state, the air outlet 220 is located on the side of the baffle 500 close to the smoke suction port 410, which arrangement ensures that the oil fume is guided into the smoke suction port 410 and forms a wind curtain for the air outlet 220.

[0123] Through the movable baffle 500, the user can adjust the opening degree of the smoke suction port 410 as needed to flexibly manage the absorption and discharge of oil fume; the design of the baffle 500 can guide the airflow in the open state, so that it more effectively covers the smoke suction port area and forms a more effective wind curtain to block the oil fume; by reasonably controlling the open state of the smoke suction port, the kitchen air conditioner can maintain efficient operation under different cooking conditions and reduce energy consumption.
