Abstract
Description
Technical Field
[0001] This invention relates to the field of integrated cooktops, and more particularly to an integrated cooktop with a cooking device. Background Technology
[0002] An integrated cooktop is a household appliance that integrates a cooktop with other kitchen appliances. In current technology, the cooktop and cooking device are generally integrated together, so that the integrated cooktop can meet the user's basic cooking operations, such as stir-frying, baking, steaming, etc.
[0003] Currently, integrated cooktops on the market generally have the cooktop mounted on top of the cooking appliance, with the gas generated by the cooking appliance being exhausted upwards through the rear side of the cooktop panel. For example, Chinese utility model patent ZL 202022216967.7 (authorization announcement number CN214370372U) discloses an integrated cooktop, including a cooking appliance and a cooktop. The cooktop includes a cooktop shell, which includes a base and a panel. The cooking appliance includes a cooking cavity, with a mounting plate above the cooking cavity. The cooktop panel has a knob hole, and the rear side of the panel has an exhaust window. The cooktop shell has a heat dissipation channel with a cooling fan and an air inlet. The air inlet of the heat dissipation channel is fluidly connected to the knob hole, and the air outlet of the heat dissipation channel is fluidly connected to the exhaust window. Furthermore, an exhaust box is provided on the lower surface of the panel at the exhaust window. A first vent is provided on the front side wall of the exhaust box, which is connected to the air outlet of the heat dissipation channel. A second vent is provided on the bottom wall of the exhaust box. The second vent is connected to the second exhaust port of the cooking cavity through an exhaust pipe.
[0004] Furthermore, current cooking appliances generally have steaming and baking functions. In order to take into account both cooking functions, existing cooking appliances cannot achieve the professional steaming and baking effects. The main problems are as follows: (1) In steaming mode, the steam in the inner pot is discharged too quickly, which makes it impossible for the steam to fully exchange heat with the food, resulting in low steam utilization and short water tank life; (2) In ordinary baking mode, the gas in the inner pot is discharged too slowly, which affects the baking effect and baking efficiency, especially when baking ingredients with high moisture content.
[0005] Regarding the issue of excessive humidity during the baking function, a forced draft method is generally used to achieve strong ventilation, as exemplified by the Chinese utility model patent with patent number ZL 202122405399.X (authorization announcement number CN216307871U). While existing forced draft methods can solve the problems of excessive humidity in the inner pot during normal baking mode and the direct spraying of residual gases (such as hot air or steam) from the inner pot when the door is opened at the end of cooking, adding an additional forced draft device increases the production cost of the cooking appliance and also complicates its internal structure. Furthermore, directly blowing cold outside air into the inner pot disrupts the uniformity of the internal temperature field, and blowing cold air directly into the inner pot after cooking also causes the cooked food to cool down. Summary of the Invention
[0006] The first technical problem to be solved by the present invention is to provide an integrated stove with a cooking device that has high cooking efficiency and good cooking effect, in contrast to the prior art.
[0007] The second technical problem to be solved by the present invention is to provide an integrated stove with cooking device that has high cooking efficiency and good cooking effect compared with the prior art. At the same time, the integrated stove can achieve strong exhaust of gas inside the inner tank without the need to add a blower device.
[0008] The third technical problem to be solved by the present invention is to provide an integrated stove with cooking device that has high cooking efficiency and good cooking effect compared with the prior art. At the same time, the integrated stove can achieve strong exhaust of gas inside the inner tank without the need to add a blower device, and the exhaust effect is good.
[0009] The fourth technical problem to be solved by the present invention is to provide an integrated stove with a cooking device that has high cooking efficiency and good cooking effect compared with the prior art. At the same time, the integrated stove can achieve strong exhaust of gas inside the inner pot without the need to add a blower device, and can avoid affecting the uniformity of the temperature field inside the inner pot.
[0010] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is as follows: an integrated stove with a cooking device, comprising a cooking device and a stove mounted on the cooking device, wherein the cooking device includes an inner liner, an exhaust port is provided on the side wall of the inner liner, the stove includes a stove shell, a heat dissipation channel is provided in the stove shell, and the stove shell includes a base with an upper opening and a panel covering the opening of the base, an exhaust window is provided on the rear side of the panel, and an exhaust box is provided on the lower surface of the panel along the left and right direction, and an air inlet fluidly communicating with the exhaust port is provided on the bottom wall of the exhaust box, and an air inlet guide fluidly communicating with the heat dissipation outlet of the heat dissipation channel is provided on the front side wall, characterized in that...
[0011] The inner liner has a first air inlet on its side wall, and the exhaust box has a second air inlet spaced laterally from the air inlet on its bottom wall. The second air inlet is in fluid communication with the first air inlet. The air inlet guide includes a first air inlet and a second air inlet spaced laterally from the side wall, with the first air inlet opposite to the air inlet and the second air inlet opposite to the second air inlet. The guide also includes a control mechanism for controlling the opening and closing of the first and second air inlets and the actual opening area.
[0012] Furthermore, in steam mode, the aforementioned first air inlet is used to exhaust gas from the inner liner, and the aforementioned control mechanism controls both the first air inlet and the second air inlet to open.
[0013] In normal baking mode, the first air vent is used to exhaust gas from the inner cavity, and the control mechanism controls both the first and second air inlets to be closed.
[0014] Furthermore, in the dehumidification baking mode or when cooking is finished, the first air vent is used to allow outside air to enter the inner cavity, and the control mechanism closes the first air vent while opening the second air vent. That is, outside air enters the exhaust box through the exhaust outlet, then sequentially through the second and first air vents into the inner cavity. The air entering the inner cavity compresses the moisture, which is quickly expelled through the exhaust outlet from the air inlet into the exhaust box, and then discharged through the exhaust outlet. This allows for rapid moisture removal during normal baking mode, preventing excessive humidity inside the inner cavity from affecting baking performance, especially when baking foods with high moisture content. At the end of cooking, the outside air entering the inner cavity compresses any remaining heat or steam, preventing it from being directly sprayed onto the user when the door is opened. Furthermore, in this invention, by closing the first air inlet and opening the second air inlet, on the one hand, the airflow from the second air inlet assists the airflow from the second air outlet (relative to the exhaust box), allowing outside air to enter the inner liner more quickly. On the other hand, since the first air inlet is closed, the airflow at the air inlet is ensured to be smooth, thereby ensuring the exhaust speed of the exhaust port. This achieves efficient removal of moisture from the inner liner during normal baking mode and residual heat or steam at the end of cooking. In addition, since the warm gas in the heat dissipation channel mixes with the airflow from the second air inlet through the airflow from the second air outlet, it prevents cold air from directly entering the inner liner and affecting the uniformity of the internal temperature field during cooking, or causing the cooked food in the inner liner to cool down at the end of cooking. Furthermore, the airflow from the second air inlet separates the airflow from the air inlet and the airflow from the second air outlet, preventing the airflow from the air inlet from mixing with the airflow from the second air outlet.
[0015] Furthermore, in the dehumidification baking mode or when cooking is finished, the actual opening area of the second air inlet is smaller. This allows the heat dissipation gas in the heat dissipation channel to enter the exhaust box at a faster speed, which in turn further accelerates the airflow speed in the second air inlet and the air intake speed of the first air inlet, thus allowing the gas in the inner liner to be discharged through the exhaust port more quickly.
[0016] Furthermore, in the dehumidification baking mode or when cooking is finished, the actual opening shape of the second air inlet is a slit extending to the left and right. This allows the airflow from the second air inlet to enter the exhaust box in a horizontal curtain shape, with a downward vector, thereby enhancing the acceleration of the airflow from the second air inlet.
[0017] Furthermore, the actual opening areas of both the first and second air inlets during the preheating stage of steam mode are smaller than their actual opening areas during the heating stage of steam mode. This ensures that the steam exhaust rate from the inner pot during the preheating stage is lower than that during the heating stage, improving the steam utilization rate during preheating and shortening the preheating time, thereby increasing the cooking efficiency in steam mode.
[0018] Furthermore, during the preheating stage of the steam mode, the actual opening shapes of both the first and second air inlets are slits extending laterally. This allows the airflow from both the first and second air inlets to enter the exhaust box in a horizontal curtain-like manner, with both carrying a downward vector. This effectively prevents air from entering the exhaust box through the air inlets and the second air inlet.
[0019] During the heating phase of the steam mode, both the first and second air inlets are fully open, which allows the steam in the inner pot to escape slowly while ensuring that the gas generated during cooking can escape smoothly.
[0020] Furthermore, the air inlet also includes a third air inlet spaced out in the left-right direction between the first air inlet and the second air inlet, and the area between the third air inlet and the second air inlet is opposite to the area between them. The control mechanism is also used to control the opening and closing of the third air inlet and the actual opening area.
[0021] Furthermore, in steam mode, the third air inlet is closed, allowing the heat dissipation gas in the heat dissipation channel to concentrate into the exhaust box through the first and second air inlets, ensuring the obstruction of airflow to the air inlets and outlets. In normal baking mode, the third air inlet is open, while the first and second air inlets are closed. Opening the third air inlet allows the heat dissipation gas in the heat dissipation channel to be smoothly exhausted through the exhaust box, ensuring effective heat dissipation for the electrical components inside the stove that generate heat during operation. In dehumidification baking mode or when cooking is finished, the third air inlet is closed, allowing the heat dissipation gas in the heat dissipation channel to concentrate into the exhaust box through the second air inlet, maximizing the acceleration of airflow from the second outlet.
[0022] Furthermore, the third air inlet consists of two spaced-apart vents. This allows for better flow of cooling gas from the heat dissipation channel into the exhaust box when all third air inlets are open.
[0023] Furthermore, the system also includes a condensate box arranged horizontally within the exhaust box. The upper part of the condensate box is open, forming a condensate outlet that communicates vertically with the exhaust window. The bottom wall of the condensate box has a first condensate inlet and a second condensate inlet spaced apart and connected side-by-side. The first condensate inlet is directly opposite the air inlet and in fluid communication with it, while the second condensate inlet is directly opposite the second air outlet and in fluid communication with it. The first air inlet, the second air inlet, and each of the third air inlets are located above the condensate box. By providing the condensate box, the condensate formed in the exhaust box can be collected, preventing condensate from flowing freely throughout the exhaust box.
[0024] Furthermore, the condensate box is vertically partitioned along the front-to-back direction, and there are two partitions spaced apart along the left-to-right direction. The air inlet is located in the space enclosed by one of the partitions and one end of the condensate box, while the second air inlet is located in the space enclosed by the other partition and the other end of the condensate box.
[0025] Furthermore, the upper ends of each partition extend vertically upwards and protrude outwards from the condensate box, and are respectively positioned between each third air inlet and the corresponding first or second air inlet. By setting up the partitions, on the one hand, the airflow in the first condensate inlet and the airflow in the second condensate inlet can be prevented from interfering with each other, especially in the dehumidification baking mode or when cooking is finished. On the other hand, by separating the two third air inlets from the first and second air inlets respectively, when the two third air inlets are closed, the airflow at the first and / or second air inlets can be prevented from spreading laterally. When the third air inlets are open, the airflow at the third air inlets can be prevented from interfering with the airflow in the first and second condensate inlets.
[0026] Furthermore, the control mechanism includes:
[0027] A self-locking motor with output shafts at both ends;
[0028] The first baffle corresponds one-to-one with the first air inlet and the second air inlet, and can be guided and slidably disposed on the front of the exhaust box where the corresponding air inlet is located, and is provided with a vertically extending first transmission rack respectively.
[0029] The first transmission assembly corresponds one-to-one with the first baffle and includes a transmission shaft extending to the left and right and a first transmission gear mounted on one end of the transmission shaft. The first transmission gear meshes with the corresponding first transmission rack.
[0030] The first clutch corresponds one-to-one with the first transmission component mentioned above and is used to control the engagement and disengagement of the other end of the corresponding transmission shaft with the corresponding output shaft of the self-locking motor.
[0031] Furthermore, when each first baffle blocks its corresponding air inlet, the corresponding air inlet is closed; when each first baffle is vertically offset from its corresponding air inlet, the corresponding air inlet is open. Thus, when each first clutch is engaged, the self-locking motor drives the corresponding transmission shafts to rotate via its output shafts at both ends. The first transmission gear on each transmission shaft rotates, and through the meshing first transmission rack, drives the corresponding first baffle to move up and down, thereby controlling the opening and closing of the corresponding air inlet. Moreover, when one first clutch is engaged and the other is disengaged, the self-locking motor only drives the first baffle corresponding to the engaged first clutch, thus controlling the opening and closing of only the air inlet located at that first baffle.
[0032] Furthermore, the air inlet also includes a third air inlet spaced apart in the left-right direction between the first air inlet and the second air inlet, and the third air inlet is opposite to the inner cavity area of the exhaust box between the air inlet and the second air inlet. Additionally, there are two third air inlets spaced apart in the left-right direction.
[0033] The aforementioned control mechanisms also include:
[0034] The second baffle corresponds to each of the third air inlets and can be slidably and vertically guided on the front of the exhaust box where the corresponding third air inlet is located, and is provided with a vertically extending second transmission rack.
[0035] The second transmission gear corresponds one-to-one with the second baffle and is used to mesh with the corresponding second transmission rack;
[0036] The third transmission gear corresponds one-to-one with the first baffle and is used to mesh with the corresponding first transmission rack.
[0037] The second clutch corresponds one-to-one with the second transmission gear and is used to control the engagement and disengagement of each second transmission gear with the corresponding third transmission gear. In this way, the control mechanism can simultaneously control the opening and closing of each third air inlet and the actual opening area, and can achieve independent control of each third air inlet by controlling the opening and closing of each second clutch.
[0038] Furthermore, a hot air baffle is provided on the rear side of the inner cavity of the liner, which, together with the rear wall of the inner cavity, forms a hot air chamber. The hot air baffle includes a hot air inlet located in the center and a hot air outlet located on the side of the hot air inlet. A hot air fan is installed on the rear wall of the inner cavity, and the impeller of the hot air fan is located in the aforementioned hot air chamber and directly opposite the aforementioned hot air inlet.
[0039] The aforementioned exhaust port is located on the rear side wall of the inner liner and within the aforementioned hot air chamber, and is situated outside the horizontal projection of the impeller onto the rear side wall of the inner liner. The aforementioned first air inlet is located on the right side wall of the inner liner and in front of the aforementioned hot air chamber, and its height is lower than that of the aforementioned exhaust port.
[0040] Furthermore, in the dehumidification baking mode or after cooking, the aforementioned hot air blower rotates at high speed, exceeding the speed in the normal baking mode. This high-speed rotation causes hot air to accumulate at the exhaust port, where the air pressure is higher than atmospheric pressure. The hot air enters the exhaust box through the air inlet from the exhaust port. At this time, a negative pressure, lower than atmospheric pressure, is created at the second air inlet of the exhaust box relative to the air inlet. Outside cold air then enters the exhaust box through the exhaust port and, through the second air inlet, enters the inner liner through the first air inlet, compressing the hot air in the inner liner from bottom to top towards the exhaust port, creating a dual-path convection circulation effect. Compared to existing technologies, this invention eliminates the need for a blower at the first air inlet; the desired exhaust effect can be achieved simply by designing the positions of the exhaust port and the first air inlet on the inner liner's side wall, as well as the speed of the hot air blower.
[0041] Furthermore, in the dehumidification baking mode or when cooking is finished, the hot air blower rotates at 1700 r / min to 2100 r / min, which can better form a dual-path convection circulation effect. In the normal baking mode, the hot air blower rotates at 1000 r / min to 1300 r / min.
[0042] Furthermore, the exhaust port is located at the upper left end of the back side wall of the inner liner, while the first air port is located at the lower rear end of the right side wall of the inner liner. This allows for a better pressure differential between the exhaust port and the first air port during dual-path convection circulation, thus ensuring a better dual-path convection circulation effect.
[0043] Furthermore, the distance between the exhaust port and the upper edge of the back wall of the inner liner is less than or equal to 1 / 3 of the height of the back wall, which is conducive to the upward movement of hot air and its accumulation at the exhaust port. Meanwhile, the distance between the first air port and the lower edge of the right side wall of the inner liner is less than or equal to 1 / 3 of the height of the right side wall, which is conducive to the downward movement of cold air at the first air port. Thus, when a dual-path convection circulation is formed, the outside air entering through the first air port can better compress the hot air in the inner liner towards the exhaust port.
[0044] Compared with the prior art, the advantages of the present invention are as follows: an exhaust port and a first air port are respectively opened on the side wall of the inner liner, and an air inlet and a second air port are respectively opened on the exhaust box. The air inlet is fluidly connected to the exhaust port, and the second air port is fluidly connected to the first air port. The front side wall of the exhaust box is respectively opened with a first air inlet and a second air inlet. The first air inlet is opposite to the air inlet, and the second air inlet is opposite to the second air port. Furthermore, the control mechanism can control the opening and closing of the first air inlet and the second air inlet and the actual opening area.
[0045] Furthermore, in steam mode, the first air vent is used to exhaust gas from the inner liner, and the control mechanism controls both the first and second air inlets to open. This allows the heat dissipation gas in the heat dissipation channel to be blown laterally into the exhaust box through the first and second air inlets, thereby obstructing the airflow from bottom to top into the exhaust box from the air inlets and the second air vent, slowing down the air intake speed of the air inlets and the second air vent, and consequently slowing down the exhaust speed of the exhaust ports and the first air vent. This allows the steam in the inner liner to fully exchange heat with the food, improving the steam heating efficiency.
[0046] In normal baking mode, the first air vent is used to exhaust gas from the inner cavity, and the control mechanism controls both the first and second air inlets to be closed. This allows the airflow from the air inlets and the first air inlet to smoothly enter the exhaust box, thereby enabling the gas in the inner cavity to be smoothly exhausted through the exhaust vent and the first air vent, accelerating the exhaust speed of the inner cavity and improving the baking effect.

[0059] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.
[0061] like Figures 1-12As shown, an integrated stove with a cooking device includes a cooking device 1 and a stove 2 mounted on the cooking device 1. The cooking device 1 includes an inner pot 11, and an exhaust port 111 is provided on the side wall of the inner pot 11. The stove 2 includes a stove shell 20, in which a heat dissipation channel 22 is provided. The stove shell 20 includes a base 202 with an upper opening and a panel 201 covering the opening of the base 202. An exhaust window 2011 is provided on the rear side of the panel 201, and an exhaust cover plate 21 is provided on the exhaust window 2011. An exhaust box 3 is provided on the lower surface of the panel 201 along the left-right direction. An air inlet 31 is provided on the bottom wall of the exhaust box 3, which is in fluid communication with the exhaust port 111, and an air inlet guide is provided on the front side wall, which is in fluid communication with the heat dissipation outlet of the heat dissipation channel 22.
[0062] Furthermore, a first air inlet 112 is provided on the side wall of the inner liner 11, and a second air inlet 32 is provided on the bottom wall of the exhaust box 3, spaced apart from the air inlet 31 in the left-right direction. The second air inlet 32 is in fluid communication with the first air inlet 112, and the air inlet guide includes a first air inlet 34 and a second air inlet 35 spaced apart in the left-right direction, wherein the first air inlet 34 is opposite to the air inlet 31, and the second air inlet 35 is opposite to the second air inlet 32. A control mechanism 5 is also included to control the opening and closing of the first air inlet 34 and the second air inlet 35 and the actual opening area.
[0063] Furthermore, in steam mode, the first air vent 112 is used to exhaust gas from the inner liner 11, and the control mechanism 5 controls both the first air inlet 34 and the second air inlet 35 to open. In this way, the heat dissipation gas in the heat dissipation channel 22 is blown laterally into the exhaust box 3 through the first air inlet 34 and the second air inlet 35, thereby obstructing the airflow entering the exhaust box 3 from bottom to top through the air inlet 31 and the second air inlet 32, slowing down the air intake speed of the air inlet 31 and the second air inlet 32, and consequently slowing down the exhaust speed of the exhaust port 111 and the first air inlet 112. This allows the steam in the inner liner 11 to fully exchange heat with the food, improving steam heating efficiency.
[0064] Furthermore, in normal baking mode, the first air vent 112 is used to exhaust gas from the inner cavity 11, and the control mechanism 5 controls both the first air inlet 34 and the second air inlet 35 to be closed. This allows the airflow from the air inlet 31 and the first air inlet 31 to smoothly enter the exhaust box 3, thereby enabling the gas in the inner cavity 11 to be smoothly exhausted through the exhaust vent 111 and the first air vent 112, accelerating the exhaust speed of the inner cavity 11 and improving the baking effect.
[0065] Furthermore, in the dehumidification baking mode or when cooking is finished, the first air vent 112 is used to allow outside air to enter the inner cavity 11, and the control mechanism 5 controls the first air inlet 34 to close and the second air inlet 35 to open. That is, at this time, outside air enters the exhaust box 3 through the exhaust port 33, and then sequentially enters the inner cavity 11 through the second air vent 32 and the first air vent 112. The air entering the inner cavity 11 compresses the moisture inside, and the moisture is quickly discharged through the exhaust port 111 from the air inlet 31 into the exhaust box 3, and then discharged through the exhaust port 33. This achieves rapid removal of moisture in normal baking mode, preventing excessive humidity inside the inner cavity 11 from affecting the baking effect, especially when baking foods with high moisture content. When cooking is finished, the outside air entering the inner cavity 11 compresses the remaining hot air or steam in the inner cavity 11, preventing the remaining hot air or steam from directly spraying onto the user when the door is opened. Furthermore, in this invention, by closing the first air inlet 34 and opening the second air inlet 35, on the one hand, the airflow from the second air inlet 35 assists the airflow from the second air outlet 32 (relative to the exhaust box 3), allowing outside air to enter the inner liner 11 more quickly; on the other hand, since the first air inlet 34 is closed, the airflow at the air inlet 31 is ensured to be smooth, thereby ensuring the exhaust speed of the exhaust outlet 111, thus achieving efficient exhaust of moisture in the inner liner 11 under normal baking mode and residual heat or steam in the inner liner 11 at the end of cooking. In addition, since the warm gas in the heat dissipation channel 22 mixes with the airflow from the second air inlet 35 into the airflow from the second air outlet 32, it can prevent cold air from directly entering the inner liner 11 and affecting the uniformity of the internal temperature field, or causing the cooked food in the inner liner 11 to cool down at the end of cooking. In addition, the airflow through the second air inlet 35 can separate the airflow at the air inlet 31 from the airflow at the second air outlet 32, preventing the airflow at the air inlet 31 from mixing with the airflow at the second air outlet 32, thus preventing the exhaust gas from re-entering the inner liner 11.
[0066] Preferably, in the dehumidification baking mode or when cooking is finished, the actual opening area of the second air inlet 35 is relatively small. This allows the heat dissipation gas in the heat dissipation channel 22 to enter the exhaust box 3 at a faster speed, which in turn further accelerates the airflow velocity in the second air inlet 32 and the air intake velocity of the first air inlet 112, allowing the gas in the inner liner 11 to be discharged more quickly through the exhaust port 111. More preferably, in the dehumidification baking mode or when cooking is finished, the actual opening shape of the second air inlet 35 is a slit extending laterally. This allows the airflow from the second air inlet 35 to enter the exhaust box 3 in a horizontal curtain shape with a downward vector, thereby enhancing the acceleration effect on the exhaust airflow in the second air inlet 32.
[0067] Furthermore, the actual opening areas of the first air inlet 34 and the second air inlet 35 during the preheating stage of the steaming mode are smaller than those during the heating stage. This allows the steam exhaust rate from the inner liner 11 during the preheating stage to be lower than that during the heating stage, improving the steam utilization rate during preheating and shortening the preheating time, thereby increasing the cooking efficiency in the steaming mode. Specifically, during the preheating stage of the steaming mode, the actual opening shapes of the first air inlet 34 and the second air inlet 35 are both horizontally extending slits, allowing the airflow from the first air inlet 34 and the second air inlet 35 to enter the exhaust box 3 in a horizontal curtain shape, with a downward vector, thus better blocking the air intake 31 and the second air inlet 31 from entering the exhaust box 3. During the heating stage of the steaming mode, the first air inlet 34 and the second air inlet 35 are fully open, allowing the gas generated during cooking to be smoothly exhausted while achieving slower steam exhaust from the inner liner 11.
[0068] Preferably, in this embodiment, the air intake direction of the first air inlet 34 and the second air inlet 35 is downward. This better blocks the airflow in the air inlet 31 and the second air outlet 32 during steaming mode, especially during the preheating stage of steaming mode, increasing the downward vector of the airflow in the first air inlet 34 and the second air inlet 35. In dehumidification baking mode or the state after cooking, the airflow in the second air inlet 35 can better accelerate the airflow at the second air outlet 32. Specifically, in this embodiment, both the first air inlet 34 and the second air inlet 35 are square holes, and the lower end of the edge of each air inlet is an inclined surface that slopes downward from the outside in relative to the exhaust box 3.
[0069] Furthermore, in this embodiment, the control mechanism 5 includes a self-locking motor 51, a first baffle 54, a first transmission assembly, and a first clutch 55. The self-locking motor 51 has output shafts at both ends. The first baffle 54 corresponds one-to-one with the first air inlet 34 and the second air inlet 35, and is slidably disposed on the front of the exhaust box 3 where the corresponding air inlet is located, and is provided with a vertically extending first transmission rack 541. The first transmission assembly corresponds one-to-one with the first baffle 54 and includes a left-right extending transmission shaft 52 and a first transmission gear 53 mounted on one end of the transmission shaft 52. The first transmission gear 53 meshes with the corresponding first transmission rack 541. The first clutch 55 corresponds one-to-one with the first transmission assembly and is used to control the engagement and disengagement of the other end of the corresponding transmission shaft 52 with the corresponding output shaft of the self-locking motor 51. Furthermore, when each first baffle 54 blocks the corresponding air inlet, the corresponding air inlet is closed; when each first baffle 54 is vertically offset from the corresponding air inlet, the corresponding air inlet is open. With all first clutches 55 engaged, the self-locking motor 51 drives the corresponding transmission shafts 52 to rotate via its output shafts at both ends. The first transmission gears 53 on each transmission shaft 52 rotate, and through their meshing first transmission racks 541, drive the corresponding first baffles 54 to move up and down, thereby controlling the opening and closing of the corresponding air inlets. Furthermore, when one first clutch 55 is engaged and the other is disengaged, the self-locking motor 51 only drives the first baffle 54 corresponding to the engaged first clutch 55, thus controlling the opening and closing of only the air inlet where that first baffle 54 is located.
[0070] Furthermore, in this embodiment, the aforementioned air inlet also includes a third air inlet 36 spaced between the first air inlet 34 and the second air inlet 35 in a left-right direction. The area between the third air inlet 36 and the air inlet 31 and the second air inlet 32 is opposite to this third air inlet. The control mechanism 5 is also used to control the opening and closing of the third air inlet 36 and the actual opening area. In steam mode, the third air inlet 36 is closed, allowing the heat dissipation gas in the heat dissipation channel 22 to concentrate and enter the exhaust box 3 through the first air inlet 34 and the second air inlet 35, ensuring obstruction of the airflow into the air inlet 31 and the second air inlet 32. In normal baking mode, the third air inlet 36 is open. At this time, both the first air inlet 34 and the second air inlet 35 are closed. Opening the third air inlet 36 allows the heat dissipation gas in the heat dissipation channel 22 to be smoothly discharged through the exhaust box 3, ensuring effective heat dissipation for the electrical components (such as the power board and display board) that generate heat during operation inside the stove 2. In the dehumidification baking mode or when cooking is finished, the third air inlet 36 is closed. This allows the heat dissipation gas in the heat dissipation channel 22 to concentrate and enter the exhaust box 3 through the second air inlet 35, maximizing the acceleration of the airflow from the second air inlet 32. Preferably, there are two third air inlets 36 spaced apart on the left and right sides, so that when each third air inlet 36 is open, the heat dissipation gas in the heat dissipation channel 22 can flow more effectively into the exhaust box 3.
[0071] Furthermore, the control mechanism 5 also includes a second baffle 56, a second transmission gear 57, a third transmission gear 58, and a second clutch 59. The second baffle 56 corresponds one-to-one with each of the third air inlets 36 and is slidably disposed on the front of the exhaust box 3 where the corresponding third air inlet 36 is located, and each baffle 56 has a vertically extending second transmission rack 561. The second transmission gear 57 corresponds one-to-one with the second baffle 56 and meshes with the corresponding second transmission rack 561. The third transmission gear 58 corresponds one-to-one with the first baffle 54 and meshes with the corresponding first transmission rack 541. The second clutch 59 corresponds one-to-one with the second transmission gear 57 and controls the engagement and disengagement of each second transmission gear 57 with the corresponding third transmission gear 58. Thus, the control mechanism 5 can simultaneously control the opening and closing of each third air inlet 36 and the actual opening area, and can achieve independent control of each third air inlet 36 by controlling the opening and closing of each second clutch 59.
[0072] Specifically, in this embodiment, the control mechanism 5 is arranged on the front surface of the exhaust box 3 in a left-right direction. The self-locking motor 51 is fixedly installed, and each first baffle 54 and each second baffle 56 is slidably installed up and down via sliding components 7. Each sliding component 7 includes a slide bar 71 protruding vertically on each baffle and a slide rail 72 fixed to the exhaust box 3. The slide 72 corresponds one-to-one with the slide bar 71, allowing the corresponding slide bar 71 to be fitted and slide back and forth. Furthermore, in this embodiment, the first air inlet 34 and the second air inlet 35 are at the same height, and each third air inlet 36 is at the same height and located above the first air inlet 34 and the second air inlet 35. Initially, each baffle blocks its corresponding air inlet. In steam mode, each first clutch 55 is closed and each second clutch 59 is disengaged. The self-locking motor 51 drives each first baffle 54 to move upward relative to the corresponding air inlet, opening the first air inlet 34 and the second air inlet 35. The actual opening area of each air inlet can be adjusted according to the upward movement distance of each first baffle 54. In normal baking mode, each first clutch 55 and each second clutch 59 is closed, and each first baffle 54 and each second baffle 56 moves downward. At this time, the first air inlet 34 and the second air inlet 35 are still blocked by the corresponding first baffle 54, while each third air inlet 36 is opened with its vertical position offset from the corresponding second baffle 56. In dehumidification baking mode or when cooking is finished, the first clutch 55 corresponding to the second air inlet 35 is closed, and the other first clutch 55 and both second clutches 59 are disengaged. The self-locking motor 51 drives the first baffle 54 corresponding to the second air inlet 35 to move upward, causing the second air inlet 35 to be partially opened.
[0073] Furthermore, the system also includes a condensate box 4 arranged horizontally within the exhaust box 3. The upper part of the condensate box 4 is open, forming a condensate outlet 43 that communicates vertically with the exhaust window 2011. The bottom wall of the condensate box 4 has a first condensate outlet 41 and a second condensate outlet 42 spaced apart and arranged side-by-side. The first condensate outlet 41 is vertically aligned with and fluidly connected to the air inlet 31, while the second condensate outlet 42 is vertically aligned with and fluidly connected to the second air inlet 32. The first air inlet 34, the second air inlet 35, and each of the third air inlets 36 are located above the condensate box 4. By providing the condensate box 4, the condensate formed in the exhaust box 3 can be collected, preventing condensate from flowing freely throughout the exhaust box 3. In this embodiment, guide sleeves 8 are vertically arranged on the inner bottom surface of the condensate box 4 outside each condensate outlet, thereby preventing mutual interference between the airflow in the first condensate outlet 41 and the second condensate outlet 42.
[0074] Furthermore, the aforementioned condensate box 4 is vertically partitioned along the front-to-back direction by two partitions 6, which are spaced apart along the left-to-right direction. The air inlet 31 is located in the space enclosed by one of the partitions and one end of the condensate box 4, while the second air inlet 32 is located in the space enclosed by the other partition 6 and the other end of the condensate box 4. Additionally, the upper ends of each partition 6 extend vertically upwards and protrude outwards from the condensate box 4, and are respectively positioned between each third air inlet 36 and the corresponding first air inlet 34 or second air inlet 35. By setting the partition 6, on the one hand, the airflow in the first condenser vent 41 and the airflow in the second condenser vent 42 can be prevented from interfering with each other, especially in the dehumidification baking mode or when cooking is finished; on the other hand, the partition 6 separates the two third air inlets 36 from the first air inlet 34 and the second air inlet 35 respectively. In this way, when the two third air inlets 36 are closed, the airflow at the first air inlet 34 and / or the second air inlet 35 can be prevented from spreading to the left and right. When the third air inlet 36 is open, the airflow at the third air inlet 36 can be prevented from interfering with the airflow in the first condenser vent 41 and the second condenser vent 42.
[0075] Furthermore, a hot air baffle 12 is provided on the rear side of the inner cavity of the inner liner 11, forming a hot air chamber 120 with the rear wall of the inner liner 11. The hot air baffle 12 includes a hot air inlet 121 located in the center and a hot air outlet 122 located on the side of the hot air inlet 121. A hot air blower 13 is installed on the rear wall of the inner liner 11, and the impeller 14 of the hot air blower 13 is located in the hot air chamber 120 and directly opposite the hot air inlet 121. The exhaust port 111 is opened on the rear wall of the inner liner 11 and located in the hot air chamber 120, and is located outside the horizontal projection of the impeller 14 on the rear wall of the inner liner 11. The first air port 112 is opened on the right side wall of the inner liner 11 and located in front of the hot air chamber 120, and the height of the first air port 112 is lower than that of the exhaust port 111. Furthermore, in the dehumidification baking mode or when cooking is finished, the hot air blower 13 rotates at high speed, and the speed of the hot air blower 13 is greater than that in the normal baking mode.
[0076] The high-speed rotation of the hot air blower 13 causes hot air to accumulate at the exhaust port 111, where the air pressure is greater than atmospheric pressure. Gas in the inner liner enters the exhaust box 3 through the air inlet 31 via the exhaust port 111. At this time, a negative pressure, lower than atmospheric pressure, is formed at the second air inlet 32 of the exhaust box 3 relative to the air inlet 31. Cold air from outside then enters the exhaust box 3 through the exhaust port 33 and enters the inner liner 11 through the second air inlet 32 and the first air inlet 112. This forces the hot air in the inner liner 11 to flow upwards towards the exhaust port 111, creating a dual-path convection circulation effect. Compared with existing technologies, this invention eliminates the need for a blower at the first air inlet 112. The desired exhaust effect can be achieved simply by designing the positions of the exhaust port 111 and the first air inlet 112 on the side wall of the inner liner 11, as well as the rotation speed of the hot air blower 13. More preferably, in the dehumidification baking mode or the state after cooking, the speed of the hot air blower 13 is 1700r / min to 2100r / min, so as to better form a dual-path convection circulation effect, while in the normal baking mode, the speed of the hot air blower 13 is 1000r / min to 1300r / min.
[0077] Furthermore, in this embodiment, the exhaust port 111 is located at the upper left end of the back sidewall of the inner liner 11, while the first air port 112 is located at the lower rear end of the right sidewall of the inner liner 11. This allows for a better pressure differential between the exhaust port 111 and the first air port 112 during dual-path convection circulation, thus better ensuring the dual-path convection circulation effect. Preferably, the distance between the exhaust port 111 and the upper edge of the back sidewall of the inner liner 11 is less than or equal to one-third of the height of the back sidewall, which facilitates the upward movement of hot air and its accumulation at the exhaust port 111. Conversely, the distance between the first air port 112 and the lower edge of the right sidewall of the inner liner 11 is less than or equal to one-third of the height of the right sidewall, which facilitates the downward movement of cold air at the first air port 112. Therefore, during dual-path convection circulation, the outside air entering through the first air port 112 can better compress the hot air in the inner liner 11 towards the exhaust port 111. Furthermore, the aforementioned exhaust port 111 and exhaust pipe 14 are connected to the air inlet 31 of the aforementioned exhaust box 3, while the aforementioned first air inlet 112 is connected to the second air inlet 32 of the aforementioned exhaust box 3 via a vent pipe 15, such as... Figure 2 As shown.
[0078] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts, collectively referred to as the first part and the second part, meaning that a fluid, gas, liquid, or a mixture of both can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first and second parts, or an indirect connection between the first and second parts through at least one third party. This third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber that allows fluid to flow through, or a combination of the above.
