Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a smoke exhaust structure of an oven and the oven. Background Art

[0002] An oven is a kitchen appliance that uses heat radiation to bake food. The baking process produces a large amount of oil smoke, and the temperature of the oil smoke is very high. It is necessary to design an exhaust structure to discharge the oil smoke reasonably.

[0003] Existing ovens typically have two types of exhaust configurations: the first connects to an external range hood, exhausting directly into the range hood's air duct; the second exhausts through the gap between the door and the display. Because the first exhaust configuration requires a range hood, its use is limited to integrated stoves. The second exhaust configuration offers greater applicability, but its location between the door and the display puts the exhaust directly into the thighs of adults or the chest and head of children. The exhaust fumes carry cooking heat, posing a high risk of burns. Utility Model Content

[0004] One of the technical problems solved by the present utility model is to provide a smoke exhaust structure for an oven, which can effectively solve the problems that the use environment of the smoke exhaust structure of the existing oven is limited and the exhaust smoke can easily burn the user, so that the smoke exhaust structure of the oven can be adapted to a variety of different use environments while reducing the risk of burns to the user.

[0005] The second technical problem solved by the present invention is to provide an oven that can effectively solve the limitations of the use environment of existing ovens and the high risk of exhaust smoke scalding users, so as to improve the applicability of the oven and avoid exhaust smoke scalding the human body.

[0006] The first technical problem mentioned above is solved by the following technical solution:

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0054] In the description of this application, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components.

[0055] like Figure 1-Figure 4 As shown, this embodiment provides an oven, comprising an inner container assembly 1, a door assembly, a bracket assembly 4, a burner assembly 5, a circulating fan assembly 10, and a display screen 9. The inner container assembly 1 includes an inner container 11 and a temperature-averaging plate 12. The door assembly is provided on the front side of the inner container 11. The door assembly includes a door frame 2 and a door body 3. The door body 3 is connected to the front side of the door frame 2. The inner container 11 is assembled on the door frame 2. A sealing strip 23 is provided between the inner container 11 and the door frame 2 to achieve a sealed connection between the inner container 11 and the door frame 2. The door frame 2 is provided on the open side of the inner container 11 and is sealed to the inner container 11. The lower end of the door body 3 is rotatably connected to the door frame 2. The temperature-averaging plate 12 is provided at the bottom of the inner container 11. The burner assembly 5 includes a burner 51 and a support frame 52. The burner 51 is fixed to the support frame 52. The support frame 52 and the temperature-averaging plate 12 enclose the burner 51 to form a combustion and heat release space for the burner 51. A circulating fan assembly 10 is mounted on the top or side wall of the inner pot 11. This circulates hot air within the inner pot 11, enabling both electric grilling and air frying. A bracket assembly 4 is connected to the upper side of the door assembly. A display screen 9 is mounted on the bracket assembly 4. The bracket assembly 4 includes a baffle 42, which secures the display screen 9 to the door frame 2.

[0056] Display screen 9 is located on the upper side of door body 3. When door body 3 rotates to close the open side of inner liner 11, a clearance 91 is formed between the bottom of display screen 9 and the top of the front end of the door assembly (i.e., the top of door body 3). In the prior art, smoke from inner liner 11 is discharged through this clearance 91. The high-temperature smoke discharged from this clearance 91 directly faces the user, posing a high risk of burns.

[0057] In order to solve the above technical problems, this embodiment also provides a smoke exhaust structure of an oven, which is applied to the above oven, such as Figure 4 As shown, the smoke exhaust structure includes a smoke exhaust hole 111, a fan 7, a first smoke exhaust channel 62, a second smoke exhaust channel 36, a drainage channel 411, and a mixing channel 8. The smoke exhaust hole 111 is located at the upper end of the inner container 11, and the fan 7 is located above the inner container 11 to draw in outside air. A smoke exhaust assembly 6 is located above the inner container 11. Since smoke generated by cooking food in the inner container 11 flows upward, the smoke flows to the upper side of the inner container 11 and then enters the smoke exhaust assembly 6, which better conforms to the flow pattern of smoke. The first smoke exhaust channel 62 is located within the smoke exhaust assembly 6 and connects to the inner container 11 through the smoke exhaust hole 111. The second smoke exhaust channel 36 is located within the door assembly and extends from the upper portion of the door assembly to the bottom of the door assembly. The bottom of the door assembly is provided with a smoke exhaust port 3511. The drainage channel 411 is located within the bracket assembly 4 and connects to the air outlet of the fan 7. A mixing channel 8 is formed between the bracket assembly 4 and the door assembly, and the mixing channel 8 is connected to the first smoke exhaust channel 62, the second smoke exhaust channel 36, and the guide channel 411 respectively. The fan 7 introduces external air into the mixing channel 8 from the guide channel 411, and after mixing with the smoke flowing into the mixing channel 8 through the first smoke exhaust channel 62, they enter the second smoke exhaust channel 36 together and are discharged through the smoke outlet 3511. The smoke exhaust structure of this oven uses the oven's own structure to exhaust smoke, and does not need to be used with a range hood. The use environment is not restricted and it is more widely applicable. The high-temperature smoke entering the mixing channel 8 from the first smoke exhaust channel 62 is mixed with the external air entering the mixing channel 8 from the guide channel 411 to reduce the temperature, and then is discharged from the bottom of the door assembly under the guidance of the external air, so that the high-temperature smoke will not flow toward the user, effectively reducing the risk of burns to the user.

[0058] In one embodiment, continue to refer to Figure 4The mixing channel 8 is provided with a first air inlet 211, a second air inlet 4211, and an exhaust port 3111, which are independent of each other. The first air inlet 211 is connected to the outlet of the first smoke exhaust channel 62, the outlet of the guide channel 411 is connected to the second air inlet 4211, and the exhaust port 3111 is connected to the inlet of the second smoke exhaust channel 36. The second air inlet 4211 is located above the exhaust port 3111. The first air inlet 211 and the fitting gap 91 are located on opposite sides of the mixing channel 8. The side of the mixing channel 8 away from the fitting gap 91 is connected to the first smoke exhaust channel 62, and the end away from the second air inlet 4211 is connected to the second smoke exhaust channel 36. The external air entering the mixing channel 8 from the second air inlet 4211 can guide the smoke entering the mixing channel 8 from the first smoke exhaust channel 62 to enter the second smoke exhaust channel 36 along the direction of extension of the second smoke exhaust channel 36, and be discharged from the air outlet end of the second smoke exhaust channel 36, thereby preventing most of the smoke from flowing to the user at the front side of the oven through the fitting gap 91. In addition, the external air and high-temperature smoke are mixed and exchanged with heat in the mixing channel 8, thereby reducing the temperature of the mixed gas. The lower temperature gas then flows out from the second smoke exhaust channel 36, further reducing the risk of burns to the user.

[0059] In one embodiment, the first air inlet 211 is positioned lower than the mating gap 91, and the flow area of ​​the exhaust port 3111 is larger than the flow area of ​​the mating gap 91. Setting the height of the mating gap 91 higher than the height of the first air inlet 211 reduces the amount of high-temperature flue gas that is not intercepted by external air and flows horizontally and is discharged through the mating gap 91.

[0060] In one embodiment, the second smoke exhaust channel 36 is arranged in the door body 3, the exhaust port 3111 is arranged at the upper part of the door body 3, the first air inlet 211 is arranged on the door frame 2, the bracket assembly 4 is connected to the door frame 2 and the second air inlet 4211 is arranged on the bracket assembly 4.

[0061] In one embodiment, the second air inlet 4211 is disposed directly opposite the exhaust port 3111, and the upper portion of the door body 3 extends obliquely downward from the side away from the door frame 2 to the side close to the door frame 2. The mixing channel 8 is connected to the second smoke exhaust channel 36 through the exhaust port 3111, and the flow area of ​​the exhaust port 3111 is larger than the area of ​​the fitting gap 91, so that the high-temperature smoke in the inner liner 11 enters the first smoke exhaust channel 62 through the smoke exhaust hole 111, and then enters the mixing channel 8 through the first air inlet 211. During the process of the external air entering the mixing channel 8 from the second air inlet 4211 and flowing toward the exhaust port 3111, most of the smoke flowing toward the fitting gap 91 is intercepted, so that most of the smoke mixes with the external air and flows toward the exhaust port 3111 in the direction of the external air flow. The flow area of ​​the exhaust port 3111 is larger than the area of ​​the fitting gap 91, so that the resistance to gas flow toward the exhaust port 3111 is smaller than the resistance toward the fitting gap 91, allowing most of the smoke to enter the second smoke exhaust channel 36 through the exhaust port 3111 and flow toward the bottom of the door assembly along the second smoke exhaust channel 36. Furthermore, the upper portion of the door body 3 is the bottom surface of the mixing channel 8, and the bottom surface of the mixing channel 8 is set to be lower than the end near the fitting gap 91 at the end near the first air inlet 211. This allows the high-temperature smoke flowing out of the first air inlet 211 to be intercepted by the outside air and then flow along with the outside air toward the exhaust port 3111 and into the second smoke exhaust channel 36, rather than moving toward the fitting gap 91. This further reduces the amount of smoke exhausted through the fitting gap 91 and is discharged from the smoke exhaust port 3511, preventing it from flowing toward the user at the front of the oven, thereby reducing the risk of burns to the user.

[0062] In one embodiment, the fitting clearance 91 is less than 2 mm, specifically, the fitting clearance 91 is 0.5 mm to 1.5 mm.

[0063] In one embodiment, if Figure 2 and Figure 5 As shown, the smoke exhaust assembly 6 includes a smoke exhaust hood 61, and a plurality of smoke exhaust holes 111 are provided on the top of the inner container 11. The smoke exhaust hood 61 is connected to the inner container 11 and covers the smoke exhaust holes 111, so that a first smoke exhaust channel 62 is formed between the smoke exhaust hood 61 and the top of the inner container 11.

[0064] Further, if Figure 5 As shown, the smoke exhaust hole 111 is provided on the side wall of the inner container 11 near the top, and the smoke exhaust cover 61 is provided on the upper side of the smoke exhaust hole 111. The specific shape of the smoke exhaust hole 111 is not limited and can be provided in various shapes such as a circular hole, an elliptical hole or a square hole according to the structure of the inner container 11.

[0065] Specifically, continue to refer to Figure 2The smoke exhaust hood 61 includes a first smoke exhaust hood 611, a second smoke exhaust hood 612, and a third smoke exhaust hood 613. The first smoke exhaust hood 611 is located on the side of the inner container 11 close to the door frame 2. The second smoke exhaust hood 612 and the third smoke exhaust hood 613 are both arranged perpendicular to the first smoke exhaust hood 611 and are respectively located at the two ends of the first smoke exhaust hood 611. The two ends of the first smoke exhaust hood 611 are respectively connected to the second smoke exhaust hood 612 and the third smoke exhaust hood 613. Smoke exhaust holes 111 are provided on both sides adjacent to the inner container 11 and the side close to the door frame 2. Of the two adjacent sides, the smoke exhaust holes 111 on one side correspond to the second smoke exhaust hood 612, and the smoke exhaust holes 111 on the other side correspond to the third smoke exhaust hood 613. The second smoke exhaust hood 612 and the inner liner 11 form a first diversion channel, the third smoke exhaust hood 613 and the inner liner 11 form a second diversion channel, and the first smoke exhaust hood 611 and the inner liner 11 form a converging channel, that is, the smoke in the inner liner 11 enters the first diversion channel and the second diversion channel respectively through the smoke exhaust holes 111 on both sides of the inner liner 11, and then enters the converging channel for convergence. The first diversion channel, the second diversion channel and the converging channel together form the first smoke exhaust channel 62. This arrangement can speed up the exhaust speed of the smoke in the inner liner 11 and prevent the smoke from accumulating at the smoke exhaust hole 111 and being unable to be discharged, resulting in an increase in the air pressure in the inner liner 11.

[0066] Of course, in other embodiments, the smoke exhaust hood 61 may be provided as an integrated structure, which can cover the circumference of the top of the inner liner 11 , and a plurality of smoke exhaust holes 111 are provided at intervals on the circumference of the top of the inner liner 11 .

[0067] The door frame 2, baffle 42, door assembly, and display screen 9 enclose a mixing channel 8. A first air inlet 211 is provided on the door frame 2, and the smoke hood 61 communicates with the mixing channel 8 through the first air inlet 211. A mating gap 91 is located in front of the mixing channel 8. A second smoke exhaust channel 36 is provided within the door body 3, extending from the top to the bottom. After entering the mixing channel 8, the smoke in the first smoke exhaust channel 62 mixes with the outside air entering the mixing channel 8 through the second air inlet 4211, where it is cooled. Guided by the outside air, the smoke flows toward the second smoke exhaust channel 36, and after entering the second smoke exhaust channel 36, it is discharged from the bottom of the second smoke exhaust channel 36. This arrangement allows the cooled smoke to be discharged from the bottom of the door body 3 along the second smoke exhaust channel 36, preventing it from coming into contact with the human body. This also extends the exhaust path of the low-temperature smoke, achieving further cooling and reducing the risk of burns.

[0068] In one embodiment, continue to refer to Figure 4The bracket assembly 4 further includes a deflector 41, a baffle 42 having one end connected to the display screen 9 and the other end extending horizontally toward the fan 7. The deflector 41 extends upwardly and obliquely from the display screen 9 toward the direction away from the display screen 9, so that an opening is formed between the deflector 41 and the end of the baffle 42 away from the display screen 9. The fan 7 is located in the opening and can bring external air into the guide channel 411.

[0069] In one embodiment, if Figure 4 and Figure 6 As shown, the baffle 42 includes a first horizontal plate 421 and a first vertical plate 422, which are arranged vertically. The first horizontal plate 421 is connected to the door frame 2, and the display screen 9 is fixed to the front side of the first vertical plate 422. Specifically, the door frame 2 includes a second vertical plate 21 and a support frame 22 arranged circumferentially around the second vertical plate 21. A notch 212 is provided in the middle of the second vertical plate 21, and the open side of the inner liner 11 is corresponding to the notch 212. The first horizontal plate 421 is fixedly attached to the upper side plate of the support frame 22. A sealing groove 213 is provided on the side of the second vertical plate 21 near the notch 212, and a sealing strip 23 is disposed within the sealing groove 213. The support frame 52 is fixedly connected to the lower side plate of the support frame 22. The lower end of the notch 212 of the second vertical plate 21 is hingedly connected to the door body 3, so that the door body 3 is rotatably arranged in front of the inner liner 11 to seal the open side of the inner liner 11. Specifically, a first air inlet 211 is provided on the second vertical plate 21. By providing a second air inlet 4211 in communication with the outside air on the first horizontal plate 421, the air deflector 41 is provided on the first horizontal plate 421, so that a guide channel 411 is formed between the air deflector 41 and the first horizontal plate 421. The fan 7 guides the outside air into the guide channel 411. The outside air in the guide channel 411 enters the mixing channel 8 through the second air inlet 4211, exchanges heat with the high-temperature flue gas entering the mixing channel 8, and then enters the second exhaust channel 36 through the exhaust port 3111 for discharge after reducing the temperature of the high-temperature flue gas. This can effectively reduce the temperature of the exhaust flue gas, lower the temperature of the user's environment, and provide higher comfort.

[0070] Specifically, a plurality of first air inlets 211 are arranged at intervals along the length direction of the merging channel, and a plurality of second air inlets 4211 are arranged at intervals along the length direction of the diversion channel 411 .

[0071] The external air is brought into the guide channel 411 by the fan 7, and then enters the mixing channel 8 through the second air inlet 4211 to mix with the high-temperature flue gas entering the mixing channel 8 through the first air inlet 211 to exchange heat to reduce the temperature of the flue gas.

[0072] In one embodiment, if Figure 4As shown, the fan 7 is configured as a crossflow fan, and an air intake gap 412 is left between the crossflow fan and one side of the opening. The air guide cover 41 gradually slopes downward from the opening to the end close to the first vertical plate 422, and the second air inlet 4211 is provided at the end of the first horizontal plate 421 away from the opening.

[0073] The deflector 41 includes a first bent plate, a deflector plate, and a second bent plate. The deflector plate gradually slopes downward from the opening toward the end near the first vertical plate 422. The first bent plate and the second bent plate are respectively provided at both ends of the deflector plate. The first bent plate bends from the end near the opening of the deflector plate to be parallel to the first horizontal plate 421, thereby forming an opening between the first bent plate and the first horizontal plate 421.

Two side panels 38 are provided, and the two side panels 38 are respectively arranged on the left and right sides of the first glass 32, the second glass 33, and the third glass 34 to close the door body 3.

[0075] Specifically, the first fixing frame 31 includes a first fixed top plate 311 and a first fixed side plate. The first fixed side plate includes a first fixed front side plate 312 and a first fixed rear side plate 313. The first fixed front side plate 312 and the first fixed rear side plate 313 are respectively connected to either side of the first fixed top plate 311. The first glass 32 is fixed to the first fixed front side plate 312, and the second glass 33 is fixed to the first fixed rear side plate 313. The second fixing frame 35 includes a second fixed top plate 351 and a second fixed side plate. The second fixed side plate includes a second fixed front side plate 352 and a second fixed rear side plate 353. The second fixed front side plate 352 and the second fixed rear side plate 353 are respectively connected to either side of the second fixed top plate 351. The connecting frame 37 includes a connecting top plate 371 and a connecting side plate. The connecting side plate includes a connecting front side plate 372 and a connecting rear side plate 373. The connecting front side plate 372 and the connecting rear side plate 373 are respectively connected to both sides of the connecting top plate 371. The connecting top plate 371 is fitted and fixed to the first fixed top plate 311. The connecting front side plate 372 is fitted and fixed to the first fixed front side plate 312. The upper end of the second glass 33 is clamped between the first fixed rear side plate 313 and the connecting rear side plate 373. The lower end of the second glass 33 is fitted and connected to the second fixed rear side plate 353. The lower end of the third glass 34 is fixed to the second fixed top plate 351.

[0076] Specifically, an exhaust port 3111 is provided on the first fixing frame 31, and the mixing channel 8 communicates with the second smoke exhaust channel 36 through the exhaust port 3111. A smoke exhaust port 3511 is provided on the second fixing frame 35, and the exhaust port 3111 is provided on the first fixed top plate 311. The smoke exhaust port 3511 is provided on the second fixed top plate 351, and the smoke exhaust port 3511 and the exhaust port 3111 are located between the second glass 33 and the third glass 34. A connecting port 3711 is provided on the connecting top plate 371. The first glass 32 protrudes from the end of the first fixing frame 31 away from the second fixing frame 35, so that the baffle 42, the door frame 2, the first fixing frame 31, and the first glass 32 enclose the mixing channel 8. Specifically, the first horizontal plate 421, the second vertical plate 21, the first fixing frame 31, and the first glass 32 enclose the mixing channel 8. Specifically, the first smoke exhaust channel 62 is located on the side of the mixing channel 8 away from the first glass 32. High-temperature smoke enters the first smoke exhaust channel 62 through the smoke exhaust hole 111 and then enters the mixing channel 8 through the first air inlet 211. Due to the guidance of external air, the flow resistance of the exhaust port 3111 being less than the flow resistance of the fitting gap 91, and the first fixed top plate 311 extending obliquely downward from the first glass 32 to the second glass 33, most of the smoke in the mixing channel 8 enters the second smoke exhaust channel 36 through the exhaust port 3111 and is discharged through the smoke exhaust port 3511. In one embodiment, the second smoke exhaust channel 36 is enclosed by the first fixing frame 31, the first glass 32, the second glass 33, and the second fixing frame 35. Specifically, the length of the second smoke exhaust channel 36 is the height of the door assembly. The low-temperature smoke generated after heat exchange in the mixing channel 8 flows from the top of the door assembly to the bottom before being discharged. This extends the discharge path of the low-temperature smoke, further reducing the temperature of the low-temperature smoke, and resulting in a lower temperature for the smoke discharged to the outside.

[0077] Furthermore, since the first glass 32 is located on the outside of the door assembly and can be directly contacted by the human body, in order to avoid the temperature of the first glass 32 that can be in direct contact with the human body from being too high, the second smoke exhaust channel 36 is set between the second glass 33 and the third glass 34 to avoid direct contact between the low-temperature flue gas and the first glass 32, which will increase the temperature of the first glass 32.

[0078] It should be noted that the exhaust port 3111, the communication port 3711, and the smoke exhaust port 3511 are all located between the second glass 33 and the third glass 34. There is no limitation on the number and shape of the first air inlet 211, the second air inlet 4211, the exhaust port 3111, the communication port 3711, and the smoke exhaust port 3511; the number can be set based on the length of their respective locations, and the shape can be set to be circular, elliptical, square, or irregular.

[0079] In one embodiment, the smoke outlet 3511 is provided with a smoke filter, which can filter out harmful substances in the smoke, thereby preventing the harmful substances in the smoke from being discharged to pollute the environment and affect human health.

[0080] The smoke exhaust structure of the oven provided in this embodiment is not restricted in the use environment and is more widely applicable. At the same time, the temperature of the smoke is effectively reduced by exchanging heat between the external air and the high-temperature smoke exhausted from the inner tank 11 and extending the exhaust path of the smoke. Furthermore, the smoke after the temperature is reduced is discharged from the bottom of the door assembly and is not easily in contact with the human body, thereby effectively reducing the risk of burns to the human body.

[0081] The oven provided in this embodiment can be a standalone gas oven or a combined steam and oven combination. The smoke exhaust structure of the oven described above can be applied to integrated stoves and cooking centers, not only improving the oven's applicability but also lowering the temperature of the smoke, preventing exhaust smoke from coming into contact with the human body and effectively reducing the risk of burns.

[0082] In the specific contents of the above-mentioned specific implementation methods, the various technical features can be combined in any non-contradictory manner. In order to make the description concise, not all possible combinations of the above-mentioned technical features are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
