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] The second viewing window is placed in the mounting groove at the bottom of the second notch. The heat insulation inner plate is installed inside the body and abuts against the second viewing window, thus fixing the second viewing window in the mounting groove. Although this assembly method is simple and convenient, as can be seen from the attached diagram of the instruction manual, the motor shaft passes through the heat insulation inner cavity and the partition plate. Therefore, during the operation of the air fryer, the vibration generated by the motor will be transmitted to the position of the second viewing window. So relying solely on the mounting groove to fix the second viewing window lacks additional fixing measures. In long-term use, the second viewing window is very prone to shaking, which will cause steam in the cooking cavity to overflow from the installation gap of the second viewing window, affecting the user experience. Utility Model Content

[0005] The purpose of this invention is to provide an air fryer that solves the problem in the prior art where the second transparent window panel is not securely installed due to motor vibration, which easily leads to steam leakage.

[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 first viewing window is formed on the front side of the mounting cavity of the body, a second viewing window is provided on the reflector, a viewing channel is formed between the first viewing window and the second viewing window, the front side of the reflector is fixed to the body by a mounting bracket, the mounting bracket is integrally formed with a viewing window pressure plate, and the viewing plate is sandwiched between the second viewing window and the viewing window pressure plate.

[0007] By adopting the above technical solution, this utility model has the following advantages: A viewing channel is formed between the first viewing window on the front side of the mounting cavity and the second viewing window opened on the reflector, allowing the user to observe the cooking process of the food in the cooking cavity located below the reflector through the viewing channel. The viewing window pressure plate of the mounting bracket presses the viewing plate tightly against the second viewing window, so that the lower part of the viewing plate abuts against the second viewing window, and the upper part of the viewing plate is pressed tightly by the viewing window pressure plate. In this way, the viewing plate is stably fixed between the viewing window pressure plate and the second viewing window, preventing the connection between the viewing plate and the second viewing window from loosening and causing steam leakage when subjected to external force. The front of the reflector is fixed to the body via a mounting bracket, increasing the stability of the reflector connection. This stability ensures the second viewing window is also relatively stable. Furthermore, the viewing window pressure plate and mounting bracket are integrally molded, reducing connection points compared to separate components and inherently providing better stability. This further guarantees the stability of the viewing plate installed in the second viewing window and prevents heat loss from the cooking cavity due to loose gaps caused by a loose viewing plate. This ensures the sealing of the cooking cavity, improves cooking results, and enhances the user experience.

[0008] Furthermore, the mounting cavity has a motor bracket for mounting the drive motor, and the viewing window pressure plate is spaced apart from the motor bracket.

[0009] By adopting the aforementioned technical solution, since the vibration generated by the drive motor is transmitted to the motor bracket when the air fryer is working, and the viewing window pressure plate is used to fix the transparent plate, the viewing window pressure plate and the motor bracket are spaced apart, which cuts off the direct transmission path of vibration from the motor bracket to the viewing window pressure plate, avoids the vibration generated by the drive motor from being transmitted to the viewing window pressure plate and causing the transparent plate to vibrate, ensures the stable installation of the transparent plate, reduces the possibility of steam leakage, and makes it easier for users to clearly observe the cooking of food in the cooking cavity.

[0010] Furthermore, the window pressure plate has a fixed end that connects to the mounting bracket and a free end opposite to the fixed end.

[0011] Using the aforementioned technical solution, the viewing panel may experience slight movement during operation or handling of the air fryer. Therefore, one end of the viewing window pressure plate is designed as a free end. This free end, compared to the fixed end, has a flexible connection with the viewing panel. When the viewing panel moves slightly, the free end can deform accordingly to adapt to the movement and maintain a tight connection. This deformation absorbs and buffers external forces, preventing stress concentration and damage. The fixed end of the viewing window pressure plate provides a stable support foundation, ensuring that the entire pressure plate does not experience significant displacement or shaking during use. This guarantees that the viewing panel is securely pressed against the second viewing window, improving structural reliability.

[0012] Furthermore, the lower end of the mounting bracket is integrally formed with a guide rail to guide the pot body into the cooking cavity.

[0013] Using the aforementioned technical solution, when the pot body is assembled into the cooking cavity, the pot body slides into the cooking cavity along the guide rail. The guide rail provides guidance for the assembly of the pot body, ensuring that the pot body always moves along the guided path, thus ensuring accurate assembly of the pot body and the cooking cavity, thereby ensuring better cooking results when the pot body is assembled into the cooking cavity.

[0014] Furthermore, the guide rails prevent the pot body from impacting the mounting bracket during assembly into the cooking cavity, thus ensuring the stability of the transparent plate on the mounting bracket.

[0015] Furthermore, a cylindrical optical channel component is provided inside the mounting cavity, a first limiting groove is provided on the outer periphery of the first viewing window of the machine body, a second limiting groove is formed at the upper end of the viewing window pressure plate, and the inner and outer ends of the optical channel component abut against the first limiting groove and the second limiting groove respectively.

[0016] Using the aforementioned technical solution, the outer end of the optical channel component is supported by the first limiting groove on the outer periphery of the first 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 second viewing window.

[0017] Furthermore, since the viewing window pressure plate presses against the second viewing window, the inner and outer ends of the light channel component abut against the outer periphery of the first and second viewing windows, respectively. Therefore, most of the light passing through the first viewing window can be guided to the second 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.

[0018] 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.

[0019] Furthermore, at least part of the sidewall of the second limiting groove supports the outer wall of the optical channel component.

[0020] Using the aforementioned technical solution, the second limiting groove can constrain the displacement of the optical channel component from the outer periphery of the optical channel component. This can be understood as at least part of the sidewall of the second limiting groove being fitted around the outer periphery of the outer wall of the optical channel component. This can reduce the radial sway of the optical channel component, ensure the structural stability of the optical channel component placed in the mounting cavity, and this installation method can reduce the gap between the optical channel component and the second limiting groove when the optical channel component abuts against it, effectively preventing the light introduced through the first viewing window from leaking out through the gap and optimizing the light guiding effect.

[0021] Furthermore, the outer end of the optical channel component is bent outward in the circumferential direction to form an abutment surface that abuts against the first limiting groove.

[0022] By adopting the aforementioned technical solution, the contact surface formed by the outward circumferential bending of the outer end of the optical channel component increases the contact 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 contact 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.

[0023] Furthermore, a third limiting groove is provided at the lower end of the viewing window pressure plate, and the viewing plate is embedded in the third limiting groove.

[0024] Using the aforementioned technical solution, since the optical channel component abuts against the window pressure plate, in order to avoid the direct contact between the inner end of the optical channel component and the transparent plate, which would cause relative compression and easily lead to the cracking of the transparent plate, the transparent plate is embedded in the third limiting groove located at the lower end of the window pressure plate, so that the installation of the optical channel component and the transparent plate are separated, avoiding direct contact between the two and extending the service life of the transparent plate.

[0025] Furthermore, the viewing channel has an inclined top surface and a bottom surface, with the intersection of the extended surfaces of the top and bottom surfaces of the channel located behind the center of the pot body.

[0026] Using the aforementioned technical solution, the extended surfaces of the inclined top and bottom surfaces of the channel intersect at the center of the pot body, which shifts the user's field of vision backward. Through the light-transmitting channel, users can observe a more distant area inside the pot body. When observing the food inside the cooking cavity, users can observe the position at the center of the pot body, allowing food that was originally located at the rear of the pot body to enter the user's field of vision.

[0027] Furthermore, the intersection of the line connecting the outer edge of the top surface of the viewing channel and the inner edge 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.

[0028] Using the aforementioned technical solution, the intersection of the connecting line and the bottom surface of the pot is located in front of the center of the pot. This allows the user's field of vision to fall on the front of the center of the pot. Through the light transmission channel, the user can observe the area in front of the center of the pot, reducing blind spots in the front of the center of the pot. Combined with the inclined top and bottom surfaces of the light transmission channel, the connection between the front and back views allows the user to achieve a wider range of observation of the pot through the light transmission channel, reducing blind spots and improving the convenience of observation.

[0039] 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.

[0040] 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, which divides 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 first viewing window 120 is formed on the front side of the mounting cavity 100a in the body 100, and a second viewing window 111 is formed on the reflector 110. A viewing channel 130 is formed between the first viewing window 120 and the second viewing window 111. The front side of the reflector 110 is fixed to the body 100 by a mounting bracket 300. A viewing window pressure plate 310 is integrally formed on the mounting bracket 300, and the viewing window pressure plate 310 presses the viewing plate tightly against the second viewing window 111.

[0041] Understandably, a viewing channel 130 is formed between the first viewing window 120 on the front side of the mounting cavity 100a and the second viewing window 111 opened in the reflector 110. The user can observe the cooking process of the food in the cooking cavity 100b located below the reflector 110 through the viewing channel 130. The viewing window pressure plate 310 of the mounting bracket 300 presses the viewing plate tightly against the second viewing window 111, so that the lower part of the viewing plate abuts against the second viewing window 111, and the upper part of the viewing plate is pressed tightly by the viewing window pressure plate 310. In this way, the viewing plate is stably fixed between the viewing window pressure plate 310 and the second viewing window 111, preventing the connection between the viewing plate and the second viewing window 111 from loosening and causing steam leakage when subjected to external force. The front side of the reflector 110 is fixed to the body 100 via the mounting bracket 300, which increases the stability of the reflector 110 connection. Therefore, the stability of the reflector 110 ensures that the second 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. The integral forming reduces the number of connection points compared to the separate setting, which inherently provides better stability. This further ensures the stability of the viewing plate installed in the second viewing window 111 and also prevents the heat in the cooking cavity 100b from escaping through the loose gaps due to the loose viewing plate, thus ensuring the sealing of the cooking cavity 100b, improving the cooking effect, and enhancing the user experience.

[0042] Furthermore, it should be noted that, for the convenience of distinguishing the perspective panels below, the perspective panel located in the second perspective window 111 is referred to as the first perspective panel 112, and the perspective panel located on the side wall of the inner liner 220 is referred to as the second perspective panel 221.

[0043] In this embodiment, taking a drawer-type air fryer as an example, the pot body 200 is detachably connected to the main body 100 and is provided with a handle 210 for easy removal. The pot body 200 is provided with an inner pot 220 for placing food. The side wall of the inner pot 220 is provided with a second transparent plate 221. The pot body 200 is provided with a viewing panel 230 at a position corresponding to the second transparent plate 221. 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.

[0044] 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 steam and 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.

[0045] In this embodiment, as Figure 1 and Figure 7As shown, the preferred viewing panel 230 and handle 210 are located on the same side of the pot body 200, and when the pot body 200 is assembled on the body 100, the first viewing window 120 and the viewing panel 230 are also located on the same side. For visual aesthetic coordination, the width D1 of the first viewing window 120 is equal to the width D2 of the viewing panel 230.

[0046] 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.

[0047] 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 is also installed at the location of the first transparent window 120. The viewing panel installed on the body 100 and the viewing panel 230 installed on 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 it is also lighter and more convenient for users of the same size.

[0048] Specifically, the front side of the air fryer in this embodiment is similar to a rectangle. Therefore, for visual aesthetics and neatness, the first 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 body 200.

[0049] In other embodiments, the shape of the first viewing window 120 and the viewing panel 230 installed on the body 100 can also be a regular shape such as a circle, or it can be set to an irregular shape. The main purpose is to observe the cooking situation inside the cooking cavity 100b.

[0050] 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.

[0051] This is because when the air fryer is working, the vibration generated by the drive motor 150 is transmitted to the motor bracket 140. The viewing window plate 310 is used to fix the first transparent 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. This avoids the vibration generated by the drive motor 150 being transmitted to the viewing window plate 310, causing the first transparent plate 112 to vibrate. This ensures the stable installation of the first transparent plate 112 and allows the user to clearly observe the cooking of the food in the cooking cavity 100b.

[0052] 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. A hot air fan 170 and a heating element 180 are installed below the reflector 110. The hot air fan 170 is used to circulate the heat generated by the heating element 180 within the cooking cavity 100b, making the heat more even within the cooking cavity 100b. 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.

[0053] 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, since the front side of the reflector 110 with the second perspective window 111 is fixed to the body 100 by the mounting bracket 300, and the body 100 itself has good stability, the position of the second perspective window 111 can be kept stable, and the first perspective plate 112 will not shake due to the vibration of the drive motor 150.

[0054] like Figure 2 , Figure 3 and Figure 6As 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 viewing window pressure plate 310 provides a stable support foundation for the entire viewing window pressure plate 310, ensuring that the entire viewing window pressure plate 310 will not undergo large displacement or shaking during use, thereby ensuring that the first viewing plate 112 can be firmly pressed against the second viewing window 111, and improving the reliability of the structure.

[0055] It should be mentioned that a slope is set on the front side of the reflector 110, where the second perspective window 111 is located. The slope gradually decreases in height from the top surface of the reflector 110 to the edge. The angle α between the slope and the horizontal plane is set within the range of 0°≤a≤90°. Compared with a horizontal setting, the inclined setting of the second perspective window 111 can increase the field of view, making it easier for users 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 slope will change, making it difficult for users to observe.

[0056] Therefore, the viewing window plate 310 and the mounting bracket 300 are connected at an angle via the fixed end 311, allowing the viewing window plate 310 to adapt to the inclined surface 113 of the reflector. Furthermore, the reflector 110 and the viewing window plate 310 will have certain tolerances during manufacturing; the free end 312 of the viewing window plate 310 can deform to compensate for these tolerances, thereby ensuring a tight fit with the second viewing window 111.

[0057] Furthermore, the lower end of the mounting bracket 300 is integrally formed with a guide rail 320 for guiding the pot body 200 to be assembled into the cooking cavity 100b. When the pot body 200 is assembled into the cooking cavity 100b, the pot body 200 slides into the cooking cavity 100b along the guide rail 320. The guide rail 320 provides guidance for the assembly of the pot body 200, so that the pot body 200 always moves along the guided path, ensuring the accuracy of the assembly of the pot body 200 and the cooking cavity 100b, thereby ensuring that the pot body 200 has a better cooking effect when it is assembled into the cooking cavity 100b.

[0058] This is because the heating element 180 is located below the reflector 110, and part of the reflector 110 is used to form the second viewing window 111. Therefore, in order to ensure that the part of the reflector 110 with the heating element 180 can completely cover the cooking cavity 100b, a guide rail 320 is added to guide the pot body 200 to be installed in the appropriate position within the cooking cavity 100b.

[0059] Furthermore, guided by the guide rail 320, the pot body 200 is prevented from impacting the mounting bracket 300 during the process of assembling into the cooking cavity 100b due to displacement. Thus, the guide rail 320's guidance of the pot body 200 also ensures the stable installation of the first transparent plate 112 on the mounting bracket 300.

[0060] like Figure 4 and Figure 5 As shown, in order to ensure that the field of view of the second perspective window 111 area is large enough, as shown in the figure, in the left and right direction, the width W1 of the second perspective window 111 / the width W2 of the reflector 110 is greater than 20%.

[0061] It is worth mentioning that, given that the second viewing window 111 occupies part of the space in the reflector 110, the area available for placing the heating element 180 is reduced. To address this, the heating element 180 is arranged in a long, spiral shape within the reflector 110. This effectively compensates for the reduced space for the heating element 180 due to the second viewing window 111, ensuring that even within the limited space, the heating element within the reflector 110 can fully guarantee the baking efficiency of the food in the cooking cavity 100b.

[0062] Furthermore, such as Figures 1 to 3 As shown, a cylindrical light channel component 190 is provided in the mounting cavity 100a. The outer end of the light channel component 190 is supported by the first limiting groove 121 on the outer periphery of the first 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 at 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 jointly 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 first viewing plate 112 can be more firmly installed in the second viewing window 111.

[0063] Furthermore, since the viewing window pressure plate 310 presses against the second viewing window 111, the inner and outer ends of the light channel component 190 abut against the outer periphery of the first viewing window 120 and the second viewing window 111, respectively. Therefore, most of the light passing through the first viewing window 120 can be guided to the second 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.

[0064] 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.

[0065] 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.

[0066] Specifically, at least a portion of the sidewall of the second limiting groove 313 supports the outer wall of the optical channel component 190 and is fixedly connected by screws, so that the second limiting groove 313 can constrain the displacement of the optical channel component 190 from the outer periphery of the optical channel component 190. It can be understood that at least a portion of the sidewall of the second limiting groove 313 is fitted around the outer periphery of the outer wall of the optical channel component 190. This can reduce the radial sway of the optical channel component 190, ensure the structural stability of the optical channel component 190 placed in the mounting cavity 100a, and this installation method can reduce the gap between the optical channel component 190 and the second limiting groove 313 when they abut against each other, effectively preventing the light introduced through the first viewing window 120 from leaking out through the gap and optimizing the light guiding effect.

[0067] 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.

[0068] In addition, 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 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.

[0069] Furthermore, the second 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.

[0070] The silicone pad 111b ensures a seal at the second 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.

[0071] It should be explained that the outer end of the cylindrical light channel component 190 mentioned above abuts against the first viewing window 120. In this embodiment, the first 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 first 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.

[0072] 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.

[0073] To be precise, the third limiting groove 314 is slightly larger than the first transparent plate 112 because a silicone pad 111b needs to be placed there. Therefore, adequate space is required to prevent the first transparent plate 112 from being subjected to excessive pressure and breaking. Thus, the 0.2mm difference between the single side of the third limiting groove 314 and the single side of the first transparent plate 112 mentioned above is only an example in this embodiment and should not be narrowly interpreted as being 0.2mm in all usage situations. The specific size should be adjusted according to the actual situation.

[0074] like Figure 1As shown by the dashed line, the transparent channel 130 has an inclined channel top surface 131 and channel bottom surface 132. The intersection of the extended surfaces of the channel top surface 131 and channel bottom surface 132 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 transparent 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 food that was originally located behind the center of the pot body 200 to enter the user's field of vision.

[0075] like Figure 1 As shown by the dashed line, the intersection of the line connecting the outer edge of the top surface of the perspective channel 130 and the inner edge of the bottom surface of the channel 132 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 transmission 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 transmission 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 transmission channel, reducing blind spots and improving the convenience of observation.

[0076] 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.

[0077] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
