Technical Field
[0001] The utility model relates to the field of household appliances, in particular to an integrated stove. Background Art
[0002] An integrated stove is a device that integrates a cooker with equipment such as a steamer or oven or a dishwasher or a disinfection cabinet. When setting up an integrated stove, the cooker is generally placed above cooking equipment such as a steamer or oven. To solve the exhaust problem of cooking equipment such as a steamer or oven, the exhaust port of the cooking equipment is generally opened behind the stove panel. In this way, when the integrated stove is working, the gas exhausted from the cooking equipment and the stove is concentratedly absorbed through the range hood above it.
[0003] For example, the Chinese utility model patent with patent number ZL201921126717.5 (authorization announcement number CN211372508U) discloses an integrated stove with a cooking device, which includes a stove and a cooking device arranged below the stove, an exhaust box is arranged in the stove shell of the stove, the panel cover is arranged on the opening of the exhaust box to enclose the exhaust cavity, and the corresponding opening of the panel forms the exhaust port, and a first inlet is opened on the bottom wall of the exhaust box, the mouth of the first inlet extends vertically downward and passes through the air inlet to form an air inlet interface exposed to the chassis, and the upper pipe mouth of the exhaust pipe is sleeved on the air inlet interface. In this working state, under the drive of the range hood above the integrated stove, the exhaust gas of the inner tank of the cooking device passes into the exhaust cavity through the exhaust pipe, and then is discharged upward through the exhaust port. The above patent realizes the upper exhaust of the cooking device by arranging an exhaust box in the stove shell, so that the stove and the cooking device can be exhausted centrally.
[0004] Furthermore, a cooking device with both steaming and baking functions has different requirements for exhaust speed in different cooking modes: faster exhaust is required in baking mode to avoid excessive humidity inside the inner pot; slower exhaust is required in steaming mode so that steam can fully exchange heat with food and improve thermal efficiency. However, the above patent cannot adjust the exhaust speed of the cooking device, so that the cooking effect in different cooking modes cannot be effectively guaranteed. In addition, the exhaust box in the above patent is generally installed in the stove shell by bonding or fixing with fasteners, which makes it inconvenient to disassemble and assemble the exhaust box.

[0008] The fourth technical problem to be solved by the present invention is to provide an integrated stove which can prevent dirt from entering the interior when not in operation, in view of the prior art.
[0009] The fifth technical problem to be solved by the utility model is to provide an integrated stove with adjustable exhaust speed and capable of preventing condensed water generated by the exhaust from flowing back into the inner pot of the cooking device in response to the prior art.

[0012] Furthermore, the top of the exhaust device is embedded in the first installation opening so that the air outlet is exposed on the upper surface of the panel, and the air inlet connector is plugged into the second installation opening so as to be exposed under the chassis.
[0013] Furthermore, when the cooking device is in the steaming mode, the actual opening area of the air outlet of the exhaust device is smaller; when the cooking device is in the baking mode, the actual opening area of the air outlet of the exhaust device is larger; and when the cooking device is not working, the air outlet of the exhaust device is closed.
[0014] Furthermore, the cross section of the cavity wall of the exhaust cavity is circular, and the air inlet connector extends along the central axis of the exhaust cavity, which is conducive to ensuring smooth exhaust of the exhaust device, and an air guide tube extending along the central axis of the exhaust cavity is convexly provided on the inner bottom surface of the exhaust cavity, and the lower end of the air guide tube is connected to the air inlet connector, and the upper end of the air guide tube is lower than the inner top surface of the exhaust cavity. The airflow entering the exhaust cavity collides with the inner top surface of the exhaust cavity, and the steam in the airflow condenses and drips and is collected in the exhaust cavity, which reduces the amount of steam discharged externally on the one hand, and prevents the formed condensed water from flowing back into the inner tank on the other hand.
[0015] Furthermore, the upper port of the air inlet joint extends vertically upward along the circumferential direction to form the air guide pipe, thereby making the internal structure of the exhaust device simple and better ensuring smooth exhaust of the exhaust device.
[0016] Furthermore, the inner top surface of the exhaust cavity is in an upwardly protruding cone shape, and the above-mentioned air outlet is formed by arranging the air outlet holes arranged at intervals along the circumferential direction at the lower end of the inner top surface, and the upper end of the above-mentioned air guide pipe is lower than the above-mentioned air outlet. In this way, the airflow entering the exhaust cavity from the air guide pipe collides with the inner top surface of the exhaust cavity, and the formed condensed water flows from top to bottom along the inner top surface and is collected in the exhaust cavity, avoiding dripping into the air guide pipe, and the remaining gas after condensation can be discharged from the air outlet.
[0017] Furthermore, a water storage ring groove is provided on the outer surface of the upper end of the exhaust device outside the air outlet along the circumferential direction, the water storage ring groove extends horizontally and opens upward, and the side wall where the air outlet is located constitutes the inner groove wall of the water storage ring groove. In this way, the condensed water in the airflow discharged from the air outlet can be collected for a second time through the water storage ring groove to prevent the condensed water from dripping on the panel of the cooker.
[0018] Furthermore, the exhaust device comprises a box body with an upper opening and a cover body, wherein the cover body is used to cover the opening of the box body and surround the exhaust cavity, thereby making the exhaust device simple in structure.

The shape of the cover body is disc-shaped, and the outer circumference of the bottom surface of the cover body is provided with an air outlet ring extending vertically along the circumferential direction. The air outlet ring is circular and is arranged concentrically with the cover body, and the air outlet ring is provided with second air outlet notches opening downward at intervals along the circumferential direction. The second air outlet notches correspond to the first air outlet notches one by one, and when the cover body and the box body are covered, the air outlet ring and the top of the box body are overlapped inside and outside so that each second air outlet notch is combined with the corresponding second air outlet notch to form a corresponding air outlet hole, and the air outlet ring and the top of the box body can rotate relative to each other along the circumferential direction. In this way, the actual opening area of the air outlet can be adjusted by the relative rotation of the cover body and the box body, thereby adjusting the exhaust speed of the cooking device.
[0020] Furthermore, a guide groove is provided on the bottom surface of the cover body outside the air outlet ring along the circumferential direction. When the cover body and the box body are closed, the top end of the box body is embedded in the guide groove and can slide along the circumferential direction of the guide groove. The guide of the guide groove can make the cover body and the box body rotate relative to each other better, thereby better adjusting the exhaust speed of the cooking device.
[0021] Furthermore, the outer surface of the top of the box body extends radially upward along the circumferential direction to form a first convex edge, the outer peripheral edge of the first convex edge extends upward along the circumferential direction to form a second convex edge, the second convex edge, the first convex edge and the top of the box body form a water storage ring groove, and when the exhaust device is installed, the first convex edge and the upper surface of the panel are abutted against each other. On the one hand, the water storage ring groove can be formed well, and on the other hand, the condensed water in the water storage ring groove can cool the panel.
[0022] Furthermore, the bottom surface of the cover body within the air outlet ring is in the shape of an upwardly protruding cone, so that the inner top surface of the exhaust chamber can be conical, which is conducive to collecting condensed water in the exhaust chamber and better preventing the condensed water from flowing back into the inner tank. The bottom surface of the cover body outside the above-mentioned guide groove is inclined downward from the outside to the inside along the circumferential direction, which is conducive to collecting condensed water in the water storage ring groove.
[0023] Furthermore, the exhaust device further comprises a mounting seat, which comprises a horizontally extending mounting plate, a central opening of the mounting plate and a mounting joint extending vertically downward formed at the bottom of the mounting plate.
[0024] When the exhaust device is installed, the installation joint is inserted into the second installation port, the installation plate abuts against the inner bottom surface of the chassis, and the air intake joint is inserted into the installation joint, so that the exhaust device can be stably set on the stove.

[0026] Furthermore, the stove also includes a left burner and a right burner spaced apart from each other, and the stove shell is also provided with a heat conducting device for transferring the residual heat of the left burner and / or the right burner to the exhaust device. In this way, the residual heat of the combustion is conducted to the exhaust device through the heat conducting device, and the condensed water collected in the exhaust device is heated, and the condensed water is evaporated by the heat, thereby achieving self-cleaning of the condensed water.
[0027] Furthermore, the heat conducting device comprises a left heat conducting sheet and a right heat conducting sheet, wherein one end of the left heat conducting sheet contacts the burner seat of the left burner, and the other end contacts one side of the mounting plate of the mounting seat, and one end of the right heat conducting sheet contacts the burner seat of the right burner, and the other end contacts the other side of the mounting plate of the mounting seat. In this way, the combustion waste heat can be better conducted to the exhaust device through the left heat conducting sheet and the right heat conducting sheet.
[0028] Compared with the prior art, the utility model has the following advantages: Compared with the prior art, the exhaust device in the utility model is installed on the cooker by embedding the top of the exhaust device in the first installation port and the air inlet joint at the bottom in the second installation port, so that the exhaust device is easy to disassemble and assemble.

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.
[0040] like Figures 1 to 8 As shown, an integrated stove includes a stove and a cooking device (not shown) located under the stove. In this embodiment, the cooking device is a steam oven, and the stove includes a stove shell 1, which includes a bottom plate 11 with an upper opening and a panel 12 covering the opening of the bottom plate 11, and the cooking device includes an inner pot.
[0041] Furthermore, a first mounting opening 120 is provided on the panel 12, and a second mounting opening 110 is provided on the bottom wall of the chassis 11. It also includes an exhaust device 2 extending up and down and used to exhaust the gas in the inner pot of the cooking device, and an exhaust cavity 20 is provided inside the exhaust device 2, and the exhaust cavity 20 has an air inlet connector 26 and an air outlet 24 with an adjustable actual opening area. The air inlet connector 26 is protruding from the bottom of the exhaust device 2 and is used to be fluidically connected with the exhaust port of the cooking device (in this embodiment, the two are connected through an exhaust pipe). In addition, the top of the exhaust device 2 is embedded in the first mounting opening 120 so that the air outlet 24 is exposed on the upper surface of the panel 12, and the air inlet connector 26 is plugged into the second mounting opening 110 and exposed under the chassis 11. Furthermore, when the cooking device is in the steaming mode, the actual opening area of the air outlet 24 of the exhaust device 2 is smaller; when the cooking device is in the baking mode, the actual opening area of the air outlet 24 of the exhaust device 2 is larger; and when the cooking device is not working, the air outlet 24 of the exhaust device 2 is closed.
[0042] As can be seen from the above, compared with the prior art, the exhaust device 2 of the utility model is installed on the cooker by embedding the top in the first installation port 120 and the air inlet joint 26 at the bottom in the second installation port 110, so that the exhaust device 2 is easy to disassemble and assemble. In addition, the air outlet 24 of the exhaust device 2 is exposed on the upper surface of the panel 12, so that the gas in the inner pot of the cooking device is smoothly discharged under the drive of the range hood above the integrated stove. Further, the actual opening area of the air outlet 24 is adjustable, and when the cooking device is in the steaming mode, the actual opening area of the air outlet 24 of the exhaust device 2 is small (the actual opening area of the air outlet 24 is in the middle state in the default initial state), then the exhaust speed of the inner pot is slow; when the cooking device is in the baking mode, the actual opening area of the air outlet 24 of the exhaust device 2 is large, then the exhaust speed of the inner pot is fast; thereby achieving the adjustable exhaust speed of the inner pot in different cooking modes, thereby ensuring the cooking effect of the cooking device in different cooking modes. In addition, when the cooking device is not in operation, the air outlet is closed, thereby preventing dirt from entering the interior of the integrated stove through the air outlet.
[0043] Furthermore, the cross section of the cavity wall of the exhaust cavity 20 is circular, and the air inlet joint 26 extends along the central axis direction of the exhaust cavity 20, which is conducive to ensuring smooth exhaust of the exhaust device 2, and an air duct 25 extending along the central axis direction of the exhaust cavity 20 is convexly provided on the inner bottom surface of the exhaust cavity 20, and the lower end of the air duct 25 is connected to the air inlet joint 26, and the upper end of the air duct 25 is lower than the inner top surface of the exhaust cavity 20. The airflow entering the exhaust cavity 20 collides with the inner top surface of the exhaust cavity 20, and the steam in the airflow condenses due to the collision, and the formed condensed water drips and is collected in the exhaust cavity 20, which reduces the amount of steam discharged, and prevents the formed condensed water from flowing back into the inner tank. Preferably, the upper port of the air inlet joint 26 extends vertically upward along the circumferential direction to form the air duct 25, so that the internal structure of the exhaust device 2 can be simple, and the smooth exhaust of the exhaust device 2 can be better ensured.
[0044] Furthermore, the inner top surface of the exhaust cavity 20 is in an upwardly protruding cone shape, and the air outlet 24 is formed by arranging the air outlet holes 240 which are arranged at intervals along the circumferential direction at the lower end of the inner top surface, and the upper end of the air guide pipe 25 is lower than the air outlet 24. In this way, the airflow entering the exhaust cavity 20 from the air guide pipe 25 collides with the inner top surface of the exhaust cavity 20, and the formed condensed water flows from top to bottom along the inner top surface and is collected in the exhaust cavity 20, avoiding dripping into the air guide pipe 25, and the remaining gas after condensation can be discharged from the air outlet 24.
[0045] Preferably, a water storage annular groove 210 is provided on the outer surface of the upper end of the exhaust device 2 outside the air outlet 24 along the circumferential direction, the water storage annular groove 210 extends horizontally and opens upward, and the side wall where the air outlet 24 is located constitutes the inner groove wall of the water storage annular groove 210. In this way, the condensed water in the airflow discharged from the air outlet 24 can be collected for a second time through the water storage annular groove 210, so as to prevent the condensed water from dripping on the panel 12 of the cooker.
[0046] Specifically, the exhaust device 2 comprises a box body 21 with an upper opening and a cover body 22, wherein the cover body 22 is used to cover the opening of the box body 21 and surround the exhaust cavity 20, so that the structure of the exhaust device 2 can be simple. The cross section of the box body 21 is circular, and the top of the box body 21 is provided with first air outlet notches 241 opening upward at intervals along the circumferential direction, and the shape of the cover body 22 is disc-shaped, and the outer circumference of the bottom surface of the cover body 22 is provided with an air outlet ring 222 extending vertically along the circumferential direction, and the air outlet ring 222 is circular and concentrically arranged with the cover body 22, and the air outlet ring 222 is provided with second air outlet notches 242 opening downward at intervals along the circumferential direction. The second air outlet notches 242 correspond to the first air outlet notches 241 one by one, and when the cover 22 is closed with the box body 21, the air outlet ring 222 and the top of the box body 21 are overlapped inside and outside so that each second air outlet notch 242 and the corresponding second air outlet notch 242 are assembled into a corresponding air outlet hole 240, and the air outlet ring 222 and the top of the box body 21 can rotate relative to each other in the circumferential direction. In this way, the actual opening area of the air outlet 24 can be adjusted by the relative rotation of the cover 22 and the box body 21, thereby adjusting the exhaust speed of the cooking device. Preferably, a guide groove 221 is opened on the bottom surface of the cover 22 outside the air outlet ring 222 in the circumferential direction, and when the cover 22 is closed with the box body 21, the top of the box body 21 is embedded in the guide groove 221 and can slide circumferentially along the guide groove 221. The guidance of the guide groove 221 enables the cover body 22 and the box body 21 to rotate relative to each other better, thereby better adjusting the exhaust speed of the cooking device.
[0047] Furthermore, there are many specific structures of the water storage annular groove 210. Specifically, in this embodiment, the outer surface of the top of the box body 21 extends radially upward along the circumferential direction to form a first convex edge 211, and the outer peripheral edge of the first convex edge 211 extends upward along the circumferential direction to form a second convex edge 212. The second convex edge 212, the first convex edge 211 and the top of the box body 21 surround the water storage annular groove 210, and when the exhaust device 2 is installed, the first convex edge 211 abuts against the upper surface of the panel 12. On the one hand, the water storage annular groove 210 can be formed well, and on the other hand, the condensed water in the water storage annular groove 210 can cool the panel 12.
[0048] In addition, preferably, in the present embodiment, the bottom surface of the cover body 22 within the above-mentioned air outlet ring 222 is in the shape of a protruding cone, so that the inner top surface of the exhaust chamber 20 can be in the shape of a cone, which is beneficial to collect condensed water in the exhaust chamber 20 and better prevent the condensed water from flowing back into the inner tank, and the bottom surface of the cover body 22 outside the above-mentioned guide groove 221 is inclined downward from the outside to the inside along the circumferential direction, so as to facilitate the collection of condensed water in the water storage ring groove 210.
[0049] Furthermore, the exhaust device 2 further comprises a mounting base 23, which comprises a horizontally extending mounting plate 231, a central opening of the mounting plate 231 and a vertically downwardly extending mounting joint 232 formed at the bottom of the mounting plate 231. When the exhaust device 2 is installed, the mounting joint 232 is plugged into the second mounting opening 110, the mounting plate 231 abuts against the inner bottom surface of the chassis 11, and the air intake joint 26 is plugged into the mounting joint 232, so that the exhaust device 2 can be stably installed on the cooker.
[0050] Furthermore, the stove also includes a left burner 31 and a right burner 32 spaced apart from each other, and the exhaust device 2 is centrally arranged between the left burner 31 and the right burner 32, and adjacent to the rear end of the panel 12. Thus, the exhaust gas of the exhaust device 2 is located below the smoking area of the range hood, which facilitates the exhaust gas of the exhaust device 2 to be sucked into the range hood. In addition, the stove also includes a left burner 31 and a right burner 32 spaced apart from each other, and the stove shell 1 is further provided with a heat conduction device for transferring the combustion waste heat of the left burner 31 and / or the right burner 32 to the exhaust device 2. In this way, the combustion waste heat is conducted to the exhaust device 2 through the heat conduction device, and the condensed water collected in the exhaust device 2 is heated, and the condensed water evaporates due to the heat, thereby achieving self-cleaning of the condensed water. Specifically, in this embodiment, the heat conducting device includes a left heat conducting sheet 41 and a right heat conducting sheet 42, wherein one end of the left heat conducting sheet 41 contacts the burner seat of the left burner 31, and the other end contacts one side of the mounting plate 231 of the mounting seat 23, and one end of the right heat conducting sheet 42 contacts the burner seat of the right burner 32, and the other end contacts the other side of the mounting plate 231 of the mounting seat 23. In this way, the combustion waste heat can be better conducted to the exhaust device 2 through the left heat conducting sheet 41 and the right heat conducting sheet 42.
