Description
Technical Field
[0001] This utility model relates to the field of small kitchen appliances, and in particular to an air fryer. Background Technology
[0002] In recent years, air fryers have become increasingly popular among consumers for their use in frying and baking food without oil. However, most air fryers on the market today have a non-visible structure, requiring users to remove the food basket during cooking to observe the food's cooking status before taking any action, resulting in a poor user experience.
[0003] To address the aforementioned issues, prior art publication CN220898515U discloses "a visual cooking device," comprising a body with an internal partition and a heat-insulating inner plate. The partition divides the body into a first cavity and a second cavity, which are distributed vertically. The heat-insulating inner plate, located within the second cavity, divides the second cavity into a heat dissipation cavity and a heating cavity, which are distributed vertically. The heating cavity has an opening on its front side that connects to the outside, and a transparent first viewing window is located above the opening on the front side of the body. The heat-insulating inner plate has a first notch on its front side that connects to the heating cavity, and the partition has a second notch on its front side corresponding to the first notch. A second viewing window is located at the position of the second notch. Users can observe the cooking status of the food inside the cooking cavity at any time through the first and second viewing windows.
[0004] During operation, the oil from the food itself or added by the user creates fumes upon heating. These fumes mix with the hot air and circulate within the heating chamber as the heating fan blades rotate. Because the second viewing window connects to this heating chamber and is lower than the heating fan blades, the airflow is slowed by the obstruction of the partition. As the air passes through the second viewing window, oil droplets easily condense on its inner side. After a period of operation, the second viewing window becomes less transparent, making it difficult for the user to clearly observe the inside of the heating chamber. This necessitates frequent cleaning of the second viewing window, negatively impacting the user experience. Utility Model Content
[0005] The purpose of this invention is to provide an air fryer that solves the problem of oil droplets forming on the viewing window mounted on the reflector, thus affecting the visibility. This invention reduces the speed at which oil droplets form on the viewing plate, ensures good visibility after long-term use, reduces the frequency of cleaning, and improves the user experience.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: an air fryer, comprising a body and a pot body, wherein a reflector is provided inside the body, the reflector dividing the space inside the body into an upper mounting cavity and a lower cooking cavity, a hot air assembly is provided inside the cooking cavity, the hot air assembly delivers hot air to the cooking cavity to heat the food, the hot air assembly includes a hot air fan and a heating tube, a first viewing window is provided on the front side of the reflector, the first viewing window is covered by a viewing plate that is inclined downward from the inside to the outside, and the lower edge of the hot air fan is located between the upper edge and the lower edge of the viewing plate.
[0007] After adopting the above technical solution, the present invention has the following advantages: the lower edge of the hot air fan is located between the upper and lower edges of the transparent plate, that is, the horizontal projection of the hot air fan onto the transparent plate will overlap with the transparent plate. Therefore, the airflow generated by the rotation of the hot air fan will blow directly onto the transparent plate, so that the airflow can maintain a certain high speed when passing through the transparent plate, thereby reducing the condensation and adsorption of oil fumes carried in the airflow on the inner side of the transparent plate, ensuring the transparency effect of the transparent plate after long-term use, reducing the frequency of user cleaning, and improving the user experience.
[0008] Furthermore, the heating element is positioned above the lower edge of the viewing plate and below its upper edge.
[0009] Using the aforementioned technical solution, the heating element continuously emits heat when in operation. Since the heating element is positioned above the lower edge of the transparent plate but below the upper edge, its horizontal projection onto the transparent plate overlaps with the plate. Therefore, the heat generated by the heating element can radiate to the transparent plate. When the air fryer is in operation, the transparent plate quickly absorbs the heat radiated by the heating element to increase its own temperature, thereby reducing the temperature difference between the transparent plate and the cooking cavity. This reduces the condensation of oil fumes in the airflow onto the surface of the transparent plate, ensuring the transparency of the plate after long-term use, reducing the frequency of cleaning, and improving the user experience.
[0010] Furthermore, the hot air assembly is offset backward relative to the center of the pot body, and the tilt angle of the rear side wall of the reflector relative to the horizontal plane is greater than the tilt angle of the transparent plate relative to the horizontal plane.
[0011] Using the aforementioned technical solution, the hot air assembly is offset backward relative to the center of the pot, shortening the distance the hot air travels to the rear wall of the reflector. Furthermore, the tilt angle of the rear wall of the reflector relative to the horizontal plane is larger than that of the viewing plate installed on the front of the reflector. This allows the hot air generated by the hot air assembly to quickly change its flow direction upon impacting the rear wall of the reflector, directing it directly into the cooking cavity below. This optimizes the flow path of the hot air within the cooking cavity, thereby reducing heat loss during the airflow process, improving heating efficiency, and reducing cooking time. Compared to the tilt angle of the rear wall of the reflector, the tilt angle of the viewing plate is gentler. Therefore, when the hot air flows along the gently tilted viewing plate, it is guided by the plate, increasing the time the hot air spends on its surface. This ensures the hot air fully heats the viewing plate, reducing the temperature difference between the viewing plate and the cooking cavity, preventing oil fumes from condensing on the viewing plate's surface, and preventing oil droplets from accumulating on the viewing plate. This ensures that the viewing panel maintains good visibility throughout long-term use, allowing users to clearly observe the cooking process of the ingredients. It also reduces the frequency of cleaning the viewing panel, thus improving the user experience.
[0012] Furthermore, an exhaust vent is provided on the side of the reflector opposite to the first viewing window. The upper edge of the exhaust vent is higher than the lower edge of the hot air fan, and the lower edge of the exhaust vent is lower than the lower edge of the hot air fan.
[0013] Using the aforementioned technical solution, when the hot air fan operates and drives airflow circulation, the airflow carrying oil fumes flows within the cooking cavity. Since the exhaust vent covers the lower edge of the hot air fan's rotation range, when the hot air fan rotates and drives the oil-fumes-laden airflow through the exhaust vent, it can expel the oil-fumes from the cooking cavity, preventing prolonged retention and accumulation of oil fumes within the cavity. This effectively reduces the concentration of oil fumes within the cooking cavity, thereby slowing the formation of oil droplets on the viewing plate. Furthermore, as the oil-fumes-laden airflow is expelled through the exhaust vent, fresh air from outside can also enter the cooking cavity. This influx of fresh air not only benefits the cooking of ingredients and optimizes their taste but also dilutes the odors produced during cooking, preventing odor residue and improving the cooking environment within the cavity, ultimately enhancing the cooking quality.
[0014] Furthermore, the angle of inclination of the front sidewall of the reflector relative to the horizontal plane is greater than the angle of inclination of the viewing plate relative to the horizontal plane.
[0015] Using the aforementioned technical solution, the tilt angle of the front sidewall of the reflector is relatively larger than that of the inclination angle of the transparent plate installed on the front side of the reflector. This allows a portion of the hot air generated by the hot air assembly to quickly change its flow direction upon impacting the front sidewall of the reflector. This portion of the hot air flows directly into the cooking cavity below, optimizing the flow path of the hot air within the cooking cavity, thereby reducing heat loss during the hot air flow process, improving heating efficiency, and reducing cooking time for the food. In contrast to the tilt angle of the front sidewall of the reflector, the inclination angle of the transparent plate is gentler. Therefore, another portion of the hot air flows along the gently angled transparent plate. Guided by the transparent plate, this portion of the hot air increases its flow time on the transparent plate surface, ensuring sufficient heating of the transparent plate, reducing the temperature difference between the transparent plate and the cooking cavity, preventing condensation of oil fumes on the transparent plate surface, and preventing oil droplets from accumulating on the transparent plate. This ensures that the viewing panel maintains good visibility throughout long-term use, allowing users to clearly observe the cooking process of the ingredients. It also reduces the frequency of cleaning the viewing panel, thus improving the user experience.
[0016] By making the tilt angle of the front sidewall of the reflector greater than the tilt angle of the transparent plate installed on the front side of the reflector, the heating efficiency of the hot air assembly for the food in the cooking cavity is ensured, while also reducing the temperature difference between the transparent plate and the cooking cavity.
[0017] Furthermore, the front side of the reflector is fixed to the body by a mounting bracket, which is integrally formed with a viewing window pressure plate, which presses the viewing plate tightly against the first viewing window.
[0018] Using the aforementioned technical solution, the viewing window pressure plate of the mounting bracket presses the transparent plate tightly against the first viewing window, thus sandwiching the transparent plate between the viewing window pressure plate and the first viewing window. The top of the transparent plate is pressed down by the viewing window pressure plate, securing the transparent plate stably between the viewing window pressure plate and the first viewing window. This prevents the connection between the transparent plate and the first viewing window from loosening, causing it to shake or fall off under external force. The front side of the reflector is fixed to the body via the mounting bracket, increasing the stability of the reflector connection. Therefore, the stability of the reflector ensures that the first viewing window is also in a relatively stable state. Furthermore, the viewing window pressure plate and the mounting bracket are integrally molded, which reduces the number of connection points compared to a separate design, thus providing better stability. This further ensures the stability of the transparent plate installed in the first viewing window and prevents heat loss from the cooking cavity due to a loose transparent plate. This ensures the sealing of the cooking cavity, improves cooking results, and enhances the user experience.
[0019] Furthermore, a second viewing window is formed on the front side of the mounting cavity of the fuselage, and a cylindrical light channel component is provided between the first viewing window and the second viewing window. A viewing channel is formed inside the light channel component. A first limiting groove is provided on the outer periphery of the second viewing window of the fuselage, and a second limiting groove is formed at the upper end of the viewing window pressure plate. The inner and outer ends of the light channel component abut against the second limiting groove and the first limiting groove, respectively.
[0020] Using the aforementioned technical solution, a viewing channel is formed between the second viewing window on the front side of the mounting cavity and the first viewing window opened on the reflector by adding a light channel component. Users can conveniently observe the cooking process of the food in the cooking cavity located below the reflector through the viewing channel.
[0021] The outer end of the optical channel component is supported by the first limiting groove on the outer periphery of the second viewing window, so that the outer end of the optical channel component abuts against the body. The inner end of the optical channel component is supported by the second limiting groove located at the upper end of the viewing window pressure plate, so that the inner end of the optical channel component can abut against the mounting bracket. The first limiting groove and the second limiting groove together fix the optical channel component, ensuring the stable installation of the optical channel component in the mounting cavity. Furthermore, while the inner end of the optical channel component is supported by the viewing window pressure plate, the optical channel component also plays a pressing role on the viewing window pressure plate, so that the viewing plate can be more firmly installed in the first viewing window.
[0022] Furthermore, since the viewing window pressure plate is pressed tightly against the first viewing window, the inner and outer ends of the light channel component surround the outer periphery of the first and second viewing windows, respectively. Therefore, most of the light passing through the second viewing window can be guided to the first viewing window, allowing more light to enter the cooking cavity. The setting of the light channel component improves the utilization rate of light, enhances the light guiding effect, and makes it convenient for users to observe the baking status of the food in the cooking cavity.
[0023] Furthermore, during the operation of the air fryer, hot steam is generated inside the cooking cavity, which creates a relatively closed viewing channel inside the light channel component. This reduces the possibility of hot steam entering the viewing channel during cooking, maintains the clarity of the viewing channel, and thus improves the observation effect.
[0024] Furthermore, the outer end of the optical channel component is bent outward in the circumferential direction to form an abutting surface that abuts against the first limiting groove; and / or, the lower end of the window pressure plate is also provided with a third limiting groove, and the transparent plate is embedded in the third limiting groove.
[0025] By adopting the aforementioned technical solution, the outward bending of the outer end of the optical channel component to form an abutment surface increases the abutment area between the outer end of the optical channel component and the first limiting groove, thereby improving the connection strength between the optical channel component and the body and enabling it to maintain a stable installation state within the mounting cavity. The abutment surface formed by bending can fit more tightly against the surface of the first limiting groove, avoiding any gaps between them and ensuring the efficiency of light introduction. And / or, since the optical channel component abuts against the viewing window pressure plate, to avoid direct contact between the inner end of the optical channel component and the viewing plate, which could cause relative compression and easily lead to breakage of the viewing plate, the viewing plate is embedded in the third limiting groove located at the lower end of the viewing window pressure plate. This separates the installation of the optical channel component and the viewing plate, avoiding direct contact between them and extending the service life of the viewing plate.
[0026] Furthermore, the extended surfaces of the inner walls of the viewing channel intersect, and the intersection point is located behind the center of the pot body.
[0027] By adopting the aforementioned technical solution, the user's field of vision is shifted to the rear, allowing them to observe a more distant area inside the pot through the light transmission channel. When observing the food inside the cooking cavity, the user can observe the rear position of the pot's center, enabling food that was originally located at the rear of the pot to enter the user's field of vision.
[0028] Furthermore, the intersection of the connecting line between the upper edge of the outer end of the top surface of the channel and the lower edge of the inner end of the bottom surface of the channel with the bottom surface of the pot body is forward relative to the center of the pot body.
[0029] By adopting the aforementioned technical solution, the user's field of vision can fall on the front center of the pot body. Through the light transmission channel, the user can observe the front center area of the pot body, reducing blind spots in the front center area of the pot body. Combined with the inclined top and bottom surfaces of the light transmission channel, the connection between the front and back fields of vision allows the user to achieve a wider observation range of the pot body through the light transmission channel, reducing blind spots and improving the convenience of observation.

[0040] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.
[0041] In this embodiment, taking a drawer-type air fryer as an example, the pot body 200 is detachably connected to the body 100 and is provided with a handle 210 for easy removal.
[0042] It should be noted that, for the convenience of those skilled in the art, the following technical solution uses an air fryer as an example only, but it is not narrowly considered that this technical solution can only be applied to air fryers, but can also be applied to small household appliances such as pizza pans.
[0043] like Figure 1 and Figure 2 As shown, this utility model provides an air fryer, including a body 100 and a pot body 200. A reflector 110 is provided inside the body 100, dividing the space inside the body 100 into an upper mounting cavity 100a and a lower cooking cavity 100b (the direction described in the embodiment is consistent with the direction indicated in the accompanying drawings). A hot air assembly is provided inside the cooking cavity 100b, which supplies hot air to the cooking cavity 100b to heat the food. The hot air assembly includes a hot air fan 170 and a heating tube 180. A first viewing window 111 is provided on the front side of the reflector 110, and a viewing plate inclined downwards from the inside to the outside is covering the first viewing window 111. The lower edge of the hot air fan 170 is located between the upper and lower edges of the viewing plate. Figure 1 The horizontal extension line O1 at the lower edge of the medium-heat fan is shown.
[0044] Understandably, the lower edge of the hot air fan 170 is located between the upper and lower edges of the transparent panel, meaning that the horizontal projection of the hot air fan 170 onto the transparent panel will overlap with the transparent panel. Therefore, the airflow generated by the rotation of the hot air fan 170 will blow directly onto the transparent panel, allowing the airflow to maintain a certain high speed when passing through the transparent panel. This reduces the condensation and adsorption of oil fumes carried by the airflow on the inner side of the transparent panel, ensuring the transparency of the transparent panel after long-term use, reducing the frequency of cleaning by the user, and improving the user experience.
[0045] To further ensure the transparency of the transparent panel after long-term use, the heating element 180 is positioned above the lower edge and below the upper edge of the transparent panel, such as... Figure 1 The horizontal extension line O2 at the lower edge of the medium-heat fan is shown. When the heating element 180 is in operation, it continuously radiates heat. Due to the installation position of the heating element 180 within the cooking cavity 100b, the horizontal projection of the heating element 180 onto the transparent plate overlaps with the transparent plate. Therefore, the heat generated by the heating element 180 can radiate to the transparent plate. Thus, when the air fryer is in operation, the transparent plate quickly absorbs the heat radiated by the heating element 180 to increase its own temperature, thereby reducing the temperature difference between the transparent plate itself and the temperature inside the cooking cavity 100b. This reduces the condensation of oil fumes in the airflow onto the surface of the transparent plate, ensuring the transparency of the transparent plate after long-term use, reducing the frequency of cleaning by the user, and improving the user experience.
[0046] Specifically, an exhaust vent 115 is provided on the side of the reflector 110 opposite to the first viewing window 111. The upper edge of the exhaust vent 115 is higher than the lower edge of the hot air fan 170, and the lower edge of the exhaust vent 115 is lower than the lower edge of the hot air fan 170. When the hot air fan 170 operates and drives airflow circulation, the airflow carrying oil fumes will flow in the cooking cavity 100b. Since the exhaust vent 115 covers the rotation range of the lower edge of the hot air fan 170, when the hot air fan 170 operates and rotates, driving the airflow carrying oil fumes to flow through the exhaust vent 115, the airflow carrying oil fumes can be discharged from the cooking cavity 100b through the exhaust vent 115, avoiding the long-term residence and accumulation of oil fumes in the cooking cavity 100b, thereby effectively reducing the concentration of oil fumes in the cooking cavity 100b, and thus reducing the speed at which oil droplets form on the viewing plate. Furthermore, as the airflow carrying oil fumes is discharged through the exhaust vent 115, fresh air from the outside can also enter the cooking chamber 100b. The replenishment of fresh air not only benefits the cooking of ingredients and optimizes their taste, but also dilutes the odors produced by the cooking ingredients, avoids odor residue, improves the cooking environment inside the cooking chamber 100b, and enhances the cooking quality.
[0047] The rear end of the aforementioned body 100 is provided with a heat dissipation hole 400 that communicates with the atmosphere. The heat dissipation hole 400 can not only dissipate heat from the electrical components inside the body 100, but also connect to the exhaust vent 115 to exhaust the airflow containing oil fumes from the cooking cavity 100b.
[0048] Furthermore, such as Figure 4 and Figure 5As shown, since the first transparent window 111 occupies part of the space of the reflector 110, the hot air assembly is offset backward relative to the center of the pot body 200. This shortens the distance that the hot air flows to the rear side wall of the reflector 110, and makes the tilt angle of the rear side wall of the reflector 110 relative to the horizontal plane relatively larger than the tilt angle of the transparent plate installed on the front side of the reflector 110 relative to the horizontal plane. In this way, the hot air generated by the hot air assembly can quickly change the flow direction of the hot air when it hits the rear side wall of the reflector 110, so that it flows directly into the cooking cavity 100b below. This optimizes the flow path of the hot air in the cooking cavity 100b, thereby reducing heat loss during the hot air flow process, improving heating efficiency, and reducing the cooking time of the food. Compared to the tilt angle of the rear side wall of the reflector 110, the tilt angle of the viewing plate is gentler. Therefore, when hot air flows along the gently tilted viewing plate, it is guided by the plate, increasing the time the hot air spends on its surface. This allows the hot air to fully heat the plate, reducing the temperature difference between the viewing plate and the cooking cavity 100b, preventing condensation of oil fumes on the plate, and preventing oil droplets from accumulating. This ensures that the viewing plate maintains good visibility throughout long-term use, allowing users to clearly observe the cooking process of the food. It also reduces the frequency of cleaning the viewing plate, improving the user experience.
[0049] It is worth mentioning that, such as Figures 1 to 4 As shown, in this embodiment, an inclined surface 113 is provided at the position of the first viewing window 111 on the front side of the reflector 110. The inclined surface 113 is inclined downward from the inside to the outside of the reflector 110. The angle α between the inclined surface 113 and the horizontal plane is set in the range of 0°≤a≤90°. The viewing plate covers the first viewing window 111 and is parallel to the inclined surface 113. The inclined setting of the first viewing window 111 can increase the field of view compared with the horizontal setting, making it convenient for the user to observe the cooking of food in the cooking cavity 100b; however, if the angle is too large (greater than 90°), the tilt direction of the inclined surface 113 will change, making it inconvenient for the user to observe.
[0050] In another embodiment, the front sidewall of the reflector 110 and the viewing plate may also have a certain angle, for example, the tilt angle of the front sidewall of the reflector 110 is greater than the tilt angle of the viewing plate.
[0051] In this embodiment, the front sidewall of the reflector 110 is also a downward inclined surface 113 from the inside out, and the mounting position of the transparent plate is recessed at an angle relative to the inclined surface 113, so that the inclination angle of the front sidewall of the reflector 110 relative to the horizontal plane is greater than the inclination angle of the transparent plate relative to the horizontal plane.
[0052] The advantage of this design is that the tilt angle of the front sidewall of the reflector 110 is relatively larger than that of the viewing plate installed in front of the reflector 110. This allows a portion of the hot air generated by the hot air assembly to quickly change its flow direction upon impacting the front sidewall of the reflector 110. This portion of the hot air flows directly into the cooking cavity 100b below, optimizing the flow path of the hot air within the cooking cavity 100b. This reduces heat loss during the hot air flow process, improves heating efficiency, and reduces cooking time. In contrast to the tilt angle of the front sidewall of the reflector 110, the viewing plate has a gentler tilt angle. Therefore, another portion of the hot air flows along the gently tilted viewing plate. Guided by the viewing plate, this portion of the hot air spends more time flowing on its surface, ensuring sufficient heating of the viewing plate. This reduces the temperature difference between the viewing plate and the cooking cavity 100b, preventing condensation of oil fumes on the viewing plate surface and preventing oil droplets from accumulating on the viewing plate. This ensures that the viewing panel maintains good visibility throughout long-term use, allowing users to clearly observe the cooking process of the ingredients. It also reduces the frequency of cleaning the viewing panel, improving the user experience.
[0053] In summary, by making the tilt angle of the front sidewall of the reflector 110 greater than the tilt angle of the transparent plate installed on the front side of the reflector 110, the heating efficiency of the hot air assembly for the food in the cooking cavity 100b is ensured, while also reducing the temperature difference between the transparent plate and the cooking cavity 100b.
[0054] like Figure 4 and Figure 5 As shown, in order to ensure that the field of view of the first perspective window 111 area is large enough, the width W1 of the first perspective window 111 / the width W2 of the reflector 110 is greater than 20% in the front-back direction.
[0055] It is worth mentioning that, given that the first perspective window 111 occupies part of the space of the reflector 110, the area available for placing the heating tube 180 is reduced. Therefore, as... Figure 5 As shown, the heating tube 180 is spirally arranged in a long strip on the reflector 110, which effectively makes up for the problem of reduced space for the heating tube 180 due to the setting of the first transparent window 111, and ensures that the heating element in the reflector 110 can fully guarantee the baking efficiency of the food in the cooking cavity 100b even in a limited space.
[0056] In this embodiment, the front side of the reflector 110 is fixed to the body 100 by the mounting bracket 300. The mounting bracket 300 is integrally formed with a window pressure plate 310, which presses the transparent plate against the first transparent window 111.
[0057] This ensures the transparent plate is stably fixed between the viewing window pressure plate 310 and the first viewing window 111, preventing the connection between the transparent plate and the first viewing window 111 from loosening, shaking, or falling off under external force. The front side of the reflector 110 is fixed to the body 100 via the mounting bracket 300, increasing the stability of the reflector 110 connection. Therefore, the stability of the reflector 110 ensures that the first viewing window 111 is also in a relatively stable state. Furthermore, the viewing window pressure plate 310 and the mounting bracket 300 are integrally formed, which reduces the number of connection points compared to separate designs, thus providing better stability. This further ensures the stability of the transparent plate installed in the first viewing window 111 and prevents heat loss from the cooking cavity 100b due to a loose transparent plate. This ensures the sealing of the cooking cavity 100b, improves cooking results, and enhances the user experience.
[0058] And, as Figures 1 to 3 As shown, a second viewing window 120 is formed on the front side of the mounting cavity 100a in the body 100. A cylindrical light channel component 190 is provided between the first viewing window 111 and the second viewing window 120. A viewing channel 130 is formed inside the light channel component 190. The user can conveniently observe the cooking of the food in the cooking cavity 100b located below the reflector 110 through the viewing channel 130.
[0059] It should be noted that the pot body 200 described above is provided with an inner pot 220 for placing food ingredients, and the side wall of the inner pot 220 is also provided with a transparent plate. For the convenience of distinguishing the transparent plates below, the transparent plate provided in the first transparent window 111 is referred to as the first transparent plate 112, and the transparent plate provided in the side wall of the inner pot 220 is referred to as the second transparent plate 221.
[0060] A viewing panel 230 is provided at a position corresponding to the second transparent plate 221 on the pot body 200. The user can observe the cooking status of the food in the inner pot 220 through the viewing panel 230 and the second transparent plate 221.
[0061] To prevent food grease from leaking through the gap between the second transparent plate 221 and the inner liner 220 during use, a sealing element is added between the second transparent plate 221 and the inner liner 220. The sealing element not only prevents grease leakage, but also makes the second transparent plate 221 and the inner liner 220 form a flexible contact, avoiding direct contact between the two and improving the service life of the second transparent plate 221.
[0062] In this embodiment, as Figure 1 and Figure 7As shown, the visible panel 230 and the handle 210 are preferably located on the same side of the pot body 200. When the pot body 200 is assembled on the body 100, the second viewing window 120 and the visible panel 230 are also located on the same side. For visual aesthetic coordination, the width D1 of the second viewing window 120 and the width D2 of the visible panel 230 are preferably equal. Of course, they can also be customized according to aesthetic coordination.
[0063] In addition, for ease of explanation, the side of the pot body 200 with the handle 210 is referred to as the front side. The visible panel 230 is not limited to being located on the same side as the handle 210. It can also be located on the rear side of the pot body 200, or on the left or right sides. However, it should be noted that the second transparent plate 221 in the inner pot 220 must correspond to the position of the visible panel 230 in order to achieve the effect of observing the food in the inner pot 220 through the visible panel 230.
[0064] Furthermore, the first transparent panel 112 and the second transparent panel 221 should be made of high-temperature resistant, food-grade glass. A viewing panel 230 is also installed at the location of the second transparent window 120. The viewing panels 230 installed on the body 100 and the pot body 200 are preferably made of transparent hard plastic. Compared to glass, this hard plastic is more drop-resistant and wear-resistant in actual use, and for the same size, it is also lighter and more convenient for users.
[0065] Specifically, the front side of the air fryer in this embodiment is similar to a rectangle. Therefore, for visual aesthetics and neatness, the second viewing window 120 is set to a rounded rectangle. The visible panel 230 installed on the body 100 is also a rounded rectangle (in order to avoid the shape of the handle 210, the upper part of the visible panel 230 has a downward recess to avoid it), so as to adapt to the shape of the front side of the air fryer and maximize the use of the space of the body 100 and the pot 200.
[0066] In other embodiments, the second viewing window 120 and the viewing panel 230 installed on the body 100 can also be in regular shapes such as circles, or they can be set to irregular shapes. The main purpose is to observe the cooking situation inside the cooking cavity 100b.
[0067] The mounting cavity 100a described above has a motor bracket 140 for mounting the drive motor 150, and the viewing window pressure plate 310 is spaced apart from the motor bracket 140.
[0068] This is because when the air fryer is working, the vibration generated by the drive motor 150 will be transmitted to the motor bracket 140. The viewing window plate 310 is used to fix the first viewing plate 112. Therefore, by setting the viewing window plate 310 and the motor bracket 140 at intervals, the direct transmission path of vibration from the motor bracket 140 to the viewing window plate 310 is cut off, avoiding the vibration generated by the drive motor 150 from being transmitted to the viewing window plate 310 and causing the first viewing plate 112 to vibrate, thus ensuring the stable installation of the first viewing plate 112.
[0069] The motor bracket 140 fixes the drive motor 150 above the reflector 110. A cooling fan 160 is also provided above the reflector 110. The cooling fan 160 is used to dissipate heat from the drive motor 150 and other electrical components inside the body 100. The motor shaft 151 of the drive motor 150 passes through the cooling fan 160 and the hot air fan 170 to drive them to work.
[0070] Therefore, as can be seen from the above, although the vibration generated when the drive motor 150 is working will also be transmitted to the reflector 110, the front side of the reflector 110 with the first transparent window 111 is fixed to the body 100 by the mounting bracket 300, and the body 100 itself has good stability, so the position of the first transparent window 111 can be kept stable and the first transparent plate 112 will not shake due to the vibration of the drive motor 150.
[0071] like Figure 6 As shown, the aforementioned window pressure plate 310 has a fixed end 311 connected to the mounting bracket 300 and a free end 312 opposite to the fixed end 311. During operation or handling of the air fryer, the first transparent plate 112 may experience slight movement. Therefore, one end of the window pressure plate 310 is designated as the free end 312. The connection between the free end 312 and the first transparent plate 112 is flexible compared to the fixed end 311. Thus, when the first transparent plate 112 experiences slight movement, the free end 312 can deform along with the movement of the first transparent plate 112 to adapt to its movement and maintain a tight connection. This deformation can absorb and buffer the impact of external forces on the first transparent plate 112, preventing stress concentration and damage to the first transparent plate 112. The fixed end 311 of the window pressure plate 310 provides a stable support foundation for the entire window pressure plate 310, ensuring that the entire window pressure plate 310 will not undergo large displacement or shaking during use, thereby ensuring that the first transparent plate 112 can be firmly pressed against the first transparent window 111, and improving the reliability of the structure.
[0072] Furthermore, as mentioned above, the first perspective plate 112 is mounted on the inclined surface 113 on the front side of the reflector 110. Therefore, the window pressure plate 310 and the mounting bracket 300 are connected at an angle through the fixed end 311, which allows the window pressure plate 310 to adapt to the inclined surface 113 of the reflector 110. In addition, the reflector 110 and the window pressure plate 310 will have certain tolerances during the manufacturing process. The free end 312 of the window pressure plate 310 can deform to compensate for the tolerances between the two, thereby ensuring a tight fit with the first perspective window 111.
[0073] Furthermore, the body 100 is provided with a first limiting groove 121 on the outer periphery of the second viewing window 120, and a second limiting groove 313 is formed at the upper end of the viewing window pressure plate 310. The inner and outer ends of the light channel component 190 respectively abut against the second limiting groove 313 and the first limiting groove 121.
[0074] The outer end of the light channel component 190 is supported by the first limiting groove 121 on the outer periphery of the second viewing window 120, so that the outer end of the light channel component 190 abuts against the body 100. The inner end of the light channel component 190 is supported by the second limiting groove 313 located on the upper end of the viewing window pressure plate 310, so that the inner end of the light channel component 190 can abut against the mounting bracket 300. The first limiting groove 121 and the second limiting groove 313 together fix the light channel component 190, ensuring the stable installation of the light channel component 190 in the mounting cavity 100a. Furthermore, while the inner end of the light channel component 190 is supported by the viewing window pressure plate 310, the light channel component 190 also plays a pressing role on the viewing window pressure plate 310, so that the viewing plate can be more firmly installed in the first viewing window 111.
[0075] Furthermore, since the viewing window pressure plate 310 is pressed against the first viewing window 111, the inner and outer ends of the light channel component 190 abut against the outer periphery of the first viewing window 111 and the second viewing window 120, respectively. Therefore, most of the light passing through the second viewing window 120 can be guided to the first viewing window 111, allowing more light to enter the cooking cavity 100b. The setting of the light channel component 190 improves the utilization rate of light, enhances the light guiding effect, and makes it convenient for users to observe the baking status of the food in the cooking cavity 100b.
[0076] Furthermore, during the operation of the air fryer, hot steam is generated in the cooking cavity 100b, which forms a relatively closed perspective channel 130 inside the light channel component 190, reducing the possibility of hot steam entering the perspective channel 130 during cooking, maintaining the clarity of the perspective channel 130, and thus improving the observation effect.
[0077] To improve visibility inside the cooking cavity 100b and facilitate user observation of the food inside, the reflector 110 is also equipped with an oven light 114 to illuminate the cooking cavity 100b when the air fryer is in operation.
[0078] Specifically, at least part of the sidewall of the second limiting groove 313 supports the outer wall of the light channel component 190 and is fixedly connected by screws, so that the second limiting groove 313 can constrain the displacement of the light channel component 190 from the outer periphery of the light channel component 190. This can reduce the gap between the light channel component 190 and the second limiting groove 313 when they abut against each other, effectively preventing the light introduced through the second viewing window 120 from leaking out through the gap and optimizing the light guiding effect.
[0079] The outer end of the optical channel component 190 is bent outward in the circumferential direction to form an abutment surface 191 that abuts against the first limiting groove 121. This increases the abutment area between the outer end of the optical channel component 190 and the first limiting groove 121, improving the connection strength between the optical channel component 190 and the body 100, allowing it to maintain a stable installation state within the mounting cavity 100a. The abutment surface 191 formed by the bending can fit more tightly against the surface of the first limiting groove 121, avoiding any gaps between them and ensuring the efficiency of light introduction.
[0080] In addition, as a preferred option, in order to avoid direct contact between the inner end of the light channel component 190 and the first transparent plate 112, which could cause relative compression and easily lead to the breakage of the first transparent plate 112, a third limiting groove 314 is also provided at the lower end of the window pressure plate 310. The first transparent plate 112 is embedded in the third limiting groove 314, so that the installation of the light channel component 190 and the first transparent plate 112 is separated, avoiding direct contact between the two.
[0081] Furthermore, the first perspective window 111 is provided with continuous flanges 111a around its circumference. The flanges 111a are used to place the flexible silicone pad 111b and limit the silicone pad 111b. The first perspective plate 112 is installed above the silicone pad 111b and then pressed by the window pressure plate 310.
[0082] The silicone pad 111b ensures the seal at the first transparent window 111, avoids rigid contact between the reflector 110 and the first transparent plate 112, and extends the service life of the first transparent plate 112.
[0083] It should be explained that the outer end of the cylindrical light channel component 190 mentioned above abuts against the second viewing window 120. In this embodiment, the second viewing window 120 is set as a rounded rectangle. Therefore, the outer end of the light channel component 190 is preferably set as a rounded rectangle with the same shape as the second viewing window 120. The inner end of the light channel component 190 is supported on the inner side of the second limiting groove 313 of the viewing window pressure plate 310. In this embodiment, the viewing window pressure plate 310 is set as a rectangle. Therefore, the shape of the inner end of the light channel component 190 is preferably set as a rectangle with the same shape as the viewing window pressure plate 310.
[0084] In the above-mentioned first transparent plate 112 is embedded in the third limiting groove 314. Therefore, the shape of the third limiting groove 314 should be consistent with the shape of the first transparent plate 112. In this embodiment, the shape of the first transparent plate 112 is preferably rectangular. Therefore, the third limiting groove 314 is preferably a rectangular groove with a single side dimension slightly larger than the single side dimension of the first transparent plate 112 by 0.2 mm.
[0085] To be precise, the third limiting groove 314 is slightly larger than the first transparent plate 112 because it needs to accommodate the silicone pad 111b111b. Therefore, adequate space is required to prevent the first transparent plate 112 from being subjected to excessive pressure and breaking. Thus, the aforementioned 0.2mm difference between the single side of the third limiting groove 314 and the single side of the first transparent plate 112 is only an example in this embodiment and should not be narrowly interpreted as being 0.2mm in all usage situations. The specific dimensions should be adjusted according to the actual situation.
[0086] like Figure 1 As shown by the dotted line, the extended surfaces of the inner walls of the perspective channel 130 intersect and the intersection point is located behind the center of the pot body 200. This shifts the user's field of vision backward, allowing them to observe a more distant area inside the pot body 200 through the light transmission channel. When the user observes the food inside the cooking cavity 100b, they can observe the position behind the center of the pot body 200, allowing the food that was originally located behind the pot body 200 to enter the user's field of vision.
[0087] The inner wall of the transparent channel 130 includes a top surface 131 and a bottom surface 132.
[0088] like Figure 1 As shown by the dashed line, the intersection of the line connecting the upper edge of the outer end of the top surface 131 of the channel and the lower edge of the inner end of the bottom surface 132 of the channel with the inner bottom surface of the pot body 200 is forward relative to the center of the pot body 200. This allows the user's field of vision to fall on the position forward of the center of the pot body 200. Through the light-transmitting channel, the user can observe the area forward of the center of the pot body 200, reducing blind spots in the area forward of the center of the pot body 200. Combined with the inclined top surface 131 and bottom surface 132 of the light-transmitting channel, the connection between the front and rear fields of vision allows the user to achieve a wider observation range of the pot body 200 through the light-transmitting channel, reducing blind spots and improving the convenience of observation.
[0089] It should be noted that, in this embodiment, the top surface 131 and bottom surface 132 of the perspective channel 130 are preferably set as smooth planes, while in other embodiments the top surface 131 and bottom surface 132 can also be set as curved surfaces.
