Description

Technical Field

[0001] The utility model relates to the field of integrated stoves, and in particular to an exhaust structure for an integrated stove and the integrated stove. Background Art

[0002] An integrated stove is a combined kitchen appliance that combines a stove, a range hood, and cooking equipment. For example, Chinese utility model patent No. ZL202222345253.5 (authorization announcement No. CN219389820U) discloses an integrated stove, including a cooking device, a stove, and a range hood, and the cooking device includes an inner pot and a door. In addition, Chinese utility model patent No. ZL202222328528.4 (authorization announcement No. CN218295814U) and Chinese utility model patent No. ZL202220338193.1 (authorization announcement No. CN217685182U) disclose existing integrated stove structures.

[0003] In order to achieve unified exhaust of integrated stoves, the gas in the inner pot of the cooking device is generally discharged into the range hood, and then discharged outside through the range hood. In terms of structure, it is generally connected to the exhaust joint on the range hood bellows through an exhaust pipe (silicone hose). At present, this exhaust method has the following problems:

[0004] (1) Since the range hood also draws in the fumes generated by the stove, the fumes may diffuse into the inner pot, causing the food in the inner pot to be tainted with the fumes. In addition, after long-term use, the oil stains may enter the silicone hose through the exhaust joint, posing a risk of the oil stains flowing back into the inner pot.

[0005] (2) The inner tank is connected to the exhaust joint of the bellows through a silicone hose, and the bellows needs to add an exhaust joint separately, which is costly;

[0006] (3) Since the inner pot of the cooking device is connected to the exhaust joint of the bellows through a silicone hose, when the cooking device is repaired, the silicone hose needs to be removed first and then pushed out, which is troublesome to disassemble and assemble;

[0007] (4) The exhaust path from the inner pot to the bellows is long, which affects the exhaust speed of the inner pot, especially the baking effect in the baking mode. Summary of the invention

[0008] The first technical problem to be solved by the utility model is to provide an exhaust structure for an integrated stove with smooth exhaust of cooking equipment and low production cost in view of the prior art.

[0009] The second technical problem to be solved by the utility model is to provide an exhaust structure for an integrated stove which can prevent the food in the inner pot from being contaminated by oil smoke in view of the prior art.

[0010] The third technical problem to be solved by the utility model is to provide an exhaust structure for an integrated stove with smooth exhaust of cooking equipment and low production cost, and the cooking equipment is easy to disassemble and assemble.

[0011] The fourth technical problem to be solved by the present invention is to provide an integrated stove having the above-mentioned exhaust structure for the integrated stove in view of the prior art.

[0012] The technical solution adopted by the utility model to solve at least one of the above-mentioned technical problems is: an exhaust structure for an integrated stove, comprising an inner pot of a cooking device and a bellows of a range hood, wherein an exhaust port is provided on the inner pot and an air inlet is provided on the bellows, and the air inlet is fluidically connected with the above-mentioned exhaust port, and is characterized in that the exhaust port and the air inlet are adjacent to each other, the two are connected through an exhaust joint, and a protective cover is provided at the air inlet of the above-mentioned bellows, and an air outlet staggered with the above-mentioned air inlet is provided on the protective cover.

[0013] Furthermore, the exhaust port and the air inlet are arranged front and back oppositely, the exhaust joint extends horizontally, and the air outlet is opened at the bottom of the protective cover. Thus, the gas in the inner tank can be discharged into the bellows more smoothly through the exhaust joint, and the air inlet and the air outlet can be staggered better, so as to better prevent oil smoke from escaping into the inner tank.

[0014] Furthermore, an arc-shaped air guide cover is provided on the inner bottom surface of the protective cover at the air outlet, and the air guide cover has an air guide port for connecting the air outlet with the inner cavity of the protective cover. In this way, the oil smoke is blocked by the air guide cover, and the amount of oil smoke entering the protective cover is further reduced, and the oil stains deposited on the air guide cover can flow down and be collected, reducing the oil stains remaining in the protective cover.

[0015] Furthermore, the bottom wall of the protective cover extends horizontally, the air outlet is semicircular, the air guide cover is vertically arranged and is in the shape of a quarter sphere, the vertical plane of the air guide cover is opened to form the air guide port, the air guide port is opposite to the air inlet, and the bottom cover opening of the air guide cover coincides with the air outlet. In this way, the movement characteristics of the air intake airflow at the air inlet and the oil fume airflow entering from the air outlet are utilized, on the one hand, the air intake airflow is ensured to enter the wind box smoothly, and on the other hand, the oil fume airflow can be better blocked on the air guide cover, and the oil stains deposited on the air guide cover can flow down better.

[0016] Furthermore, the protective cover is square in shape and is arranged front and rear opposite to the air inlet, and the air outlet is at least two and is arranged on the bottom wall of the protective cover at intervals in the left and right directions. Thus, the gas can be discharged into the wind box relatively smoothly, ensuring a smooth flow field inside the inner tank, and further ensuring a uniform temperature field inside the inner tank.

[0017] Furthermore, the first end of the exhaust connector is fixed to the exhaust port of the inner pot, and the second end is plugged into the air inlet of the bellows. In this way, when disassembling the cooking device, the cooking device can be directly pulled out, and when installing, the cooking device can be pushed in and the second end of the exhaust connector can be inserted into the air inlet.

[0018] Furthermore, the exhaust connector is in the shape of a circular tube, and a radially extending limiting edge is protruded on the outer peripheral surface of the first end along the circumferential direction, and the limiting edge is located in the inner tank.

[0019] The invention also comprises a nut threadedly connected to the first end of the exhaust connector, the nut locks the exhaust connector with the inner container and makes the above-mentioned limiting edge abut against the inner edge of the exhaust port along the circumferential direction, so that the exhaust connector can be firmly fixed on the inner container.

[0020] Furthermore, the edge of the air inlet extends circumferentially toward the inside of the bellows to form a guide sleeve, which is truncated and narrows from the outside to the inside of the bellows, and the minimum radius of the guide sleeve is greater than or equal to the radius of the second end of the exhaust connector. In this way, the guide sleeve can guide the movement of the second end of the exhaust connector relative to the air inlet, so that the exhaust connector can be better inserted into the air inlet.

[0021] Furthermore, the invention also includes a sealing ring which is sleeved on the second end of the exhaust joint and is used to seal the circumferential gap between the second end and the air inlet, so as to prevent the gas in the bellows from leaking from the air inlet, especially the oil fume gas.

[0022] Furthermore, a partition is provided between the inner liner and the bellows, and a mounting opening is provided on the partition for the exhaust joint to pass through. The sealing ring is cylindrical and extends along the axial direction of the exhaust joint. The first end of the sealing ring is clamped between the edge of the mounting opening and the outer peripheral surface of the exhaust joint along the circumferential direction, and the second end is clamped between the partition and the corresponding side plate of the bellows along the axial direction, and deforms and expands in the radial direction from the partition to the bellows, and the end edge of the second end abuts against the outer edge of the air inlet along the circumferential direction. On the one hand, the sealing ring can be stably installed, and on the other hand, the sealing ring can better seal the gap between the second end of the exhaust joint and the air inlet.

[0023] Furthermore, the outer circumferential surface of the first end of the sealing ring is concave inwardly along the circumferential direction to form a mounting groove for the edge of the mounting port to be embedded, and the inner circumferential surface of the first end is provided with at least one radially extending sealing flange, which abuts against the outer circumferential surface of the exhaust joint along the circumferential direction. On the one hand, the sealing ring can be installed more stably, and on the other hand, the air inlet can be secondary sealed to improve the sealing effect.

[0024] The technical solution adopted to further solve the fourth technical problem mentioned above is: an integrated stove, characterized in that it includes the exhaust structure for the integrated stove as described above.

[0025] Compared with the prior art, the advantages of the utility model are that the exhaust port and the air inlet are adjacent to each other and are connected via an exhaust joint, that is, the exhaust port and the air inlet are connected only via the exhaust joint. Compared with the prior art, the production cost is reduced, the exhaust path of the inner pot can be relatively shortened, and the exhaust is smoother, thereby ensuring the cooking effect.

[0026] Furthermore, by providing a protective cover on the air inlet, on the one hand, it can prevent the negative pressure in the bellows from directly acting on the exhaust port and causing heat loss in the inner pot; on the other hand, it can prevent the oil smoke in the bellows from directly diffusing into the inner pot through the air inlet and causing the food in the inner pot to be contaminated by the oil smoke.

For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] like Figures 1 to 5 As shown, an integrated stove comprises a cooking device 1, a stove 3 and a range hood 2, wherein the stove 2 is arranged above the cooking device 1, and the range hood 2 is arranged behind the cooking device 1. Further, it also comprises an exhaust structure, which comprises an inner pot 10 of the cooking device 1 and a bellows 20 of the range hood 2. The inner pot 10 is provided with an exhaust port 101 and the bellows 20 is provided with an air inlet 201, the air inlet 201 is in fluid communication with the exhaust port 101, the exhaust port 101 and the air inlet 201 are arranged adjacent to each other, and the two are connected through an exhaust joint 5, and a protective cover 8 is provided at the air inlet 201 in the bellows 20, and an air outlet 80 is provided on the protective cover 8 and is arranged staggered with the air inlet 201. The fan 21 of the range hood 2 is installed in the bellows 20.

[0035] As can be seen from the above, the exhaust port 101 and the air inlet 201 in the utility model are adjacently arranged, and the two are connected through the exhaust joint 5, that is, the exhaust port 101 and the air inlet 201 are connected only through the exhaust joint 5. Compared with the prior art, the production cost is reduced, and the exhaust path of the inner pot 10 can be relatively shortened, and the exhaust is smoother, thereby ensuring the cooking effect. Further, by covering the air inlet 201 with a protective cover 8, on the one hand, it can prevent the negative pressure in the bellows 20 from directly acting on the exhaust port 101 and causing heat loss in the inner pot 10, and on the other hand, it can prevent the oil smoke in the bellows 20 from directly diffusing into the inner pot 10 through the air inlet 201 and causing the food in the inner pot 10 to be tainted by the oil smoke.

[0036] Furthermore, the exhaust port 101 and the air inlet 201 are arranged front to back, the exhaust joint 5 extends horizontally in the front-to-back direction, and the air outlet 80 is provided at the bottom of the protective cover 8. Thus, the gas in the inner liner 10 can be discharged into the bellows 20 more smoothly through the exhaust joint 5, and the air inlet 201 and the air outlet 80 can be staggered better, so as to better prevent the oil smoke from escaping into the inner liner 10. Specifically, in this embodiment, the exhaust port 101 is provided on the back plate of the inner liner 10, and the air inlet 201 is provided on the front side plate of the bellows 20, and the exhaust port 101 is located above the back plate of the inner liner 10.

[0037] Furthermore, an arc-shaped air guide cover 81 is provided on the inner bottom surface of the protective cover 8 at the air outlet 80, and the air guide cover 81 has an air guide port 810 for connecting the air outlet 80 with the inner cavity of the protective cover 8. In this way, the oil smoke is blocked by the air guide cover 81, and the amount of oil smoke entering the protective cover 8 is further reduced, and the oil stains deposited on the air guide cover 81 can flow down and be collected, reducing the oil stains remaining in the protective cover 8. Preferably, the bottom wall of the protective cover 8 extends horizontally, the air outlet 80 is semicircular, the air guide cover 81 is vertically arranged and is in the shape of a quarter sphere, and the vertical plane of the air guide cover 81 is opened to form the air guide port 810, which is opposite to the air inlet 201, and the bottom cover port of the air guide cover 81 coincides with the air outlet 80. In this way, the movement characteristics of the air flow at the air inlet 201 and the oil fume flow entering from the air outlet 80 are utilized to ensure that the air flow enters the bellows 20 smoothly on the one hand, and the oil fume flow can be better blocked on the guide cover 81 on the other hand, and the oil stains deposited on the guide cover 81 can flow down better. Further preferably, the protective cover 8 is square in shape and is arranged front and back opposite to the air inlet 201, and the air outlet 80 is at least two (specifically three in this embodiment) and is arranged on the bottom wall of the protective cover 8 at intervals in the left and right directions. Thereby, the gas can be discharged into the bellows 20 relatively smoothly, ensuring the smooth flow field inside the inner liner 10, and then ensuring the uniformity of the temperature field inside the inner liner 10.

[0038] Furthermore, the first end of the exhaust connector 5 is fixed to the exhaust port 101 of the inner pot 10, and the second end is inserted into the air inlet 201 of the bellows 20. In this way, when disassembling the cooking device 1, it is only necessary to directly pull out the cooking device 1, and when installing, it is only necessary to push the cooking device 1 in and insert the second end of the exhaust connector 5 into the air inlet 201. Specifically, the exhaust connector 5 is in the shape of a circular tube, and a radially extending limiting rim 51 is protruded on the outer circumferential surface of the first end along the circumferential direction, and the limiting rim 51 is located in the inner pot 10. It also includes a nut 6 threadedly connected to the first end of the exhaust connector 5, and the nut 6 locks the exhaust connector 5 with the inner pot 10 and makes the limiting rim 51 abut against the inner edge of the exhaust port 101 along the circumferential direction, so that the exhaust connector 5 can be firmly fixed on the inner pot 10.

[0039] Furthermore, the edge of the air inlet 201 extends circumferentially toward the inside of the bellows 20 to form a guide sleeve 2011, which is truncated and narrows from the outside to the inside of the bellows 20, and the minimum radius of the guide sleeve 2011 is greater than or equal to the radius of the second end of the exhaust connector 5. In this way, the guide sleeve 2011 can guide the movement of the second end of the exhaust connector 5 relative to the air inlet 201, so that the exhaust connector 5 can be better inserted into the air inlet 201. Preferably, a sealing ring 7 is further included, which is sleeved on the second end of the exhaust connector 5 and is used to seal the circumferential gap between the second end and the air inlet 201. In this way, the gas in the bellows 20 can be prevented from leaking from the air inlet 201, especially the oil fume gas.

[0040] Furthermore, a partition plate 4 extending left and right is vertically arranged between the inner liner 10 and the bellows 20, and a mounting port 40 for the exhaust joint 5 to pass through is provided on the partition plate 4. The sealing ring 7 is cylindrical and extends along the axial direction of the exhaust joint 5. The first end of the sealing ring 7 is clamped between the edge of the mounting port 40 and the outer peripheral surface of the exhaust joint 5 along the circumferential direction, and the second end is clamped between the partition plate 4 and the corresponding side plate of the bellows 20 along the axial direction, and is deformed and expanded in the radial direction from the partition plate 4 to the bellows 20, and the end edge of the second end is against the outer edge of the air inlet 201 along the circumferential direction. On the one hand, the sealing ring 7 can be stably installed, and on the other hand, the sealing ring 7 can better seal the gap between the second end of the exhaust joint 5 and the air inlet 201.
