Description

Technical Field

[0001] This invention relates to the field of cooking equipment, and more particularly to a cooking device. Background Technology

[0002] Steam ovens and other cooking appliances use steam to heat food placed inside the inner cavity. The steam generator used to produce steam can be either built-in or external. Built-in steam generators are generally heating plates installed on the bottom wall of the inner cavity. During cooking, water from the water tank is introduced into the inner cavity, and the heating plate heats the water to generate steam. Examples include Chinese utility model patents ZL202120331807.9 (authorization announcement number CN217218730U) and ZL202010620846.0 (authorization announcement number CN111820728A). Furthermore, when the heating plate is working, current continuously flows through the relay, causing a high temperature rise in the power board. When the heating plate stops working, no current flows through the relay, and the temperature rise of the power board is generally not very high. Therefore, when the heating plate is working, the power board needs to be cooled to prevent excessive temperature rise, which could affect the normal operation of the cooking appliance.

[0003] Furthermore, the water tank assembly of cooking equipment generally consists of a water tank base and a water tank housed within the base. When adding water, the water tank must be removed from the base, and after adding water, it must be pushed back into the base. During this process, water from the tank may overflow and spill into the inside of the water tank base, which is difficult to clean, especially for top-mounted water tank assemblies. The constantly damp environment inside the water tank base can easily lead to bacterial growth, thus posing a potential safety hazard for cooking. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a cooking device with a compact structure that can dissipate heat from electrical components that generate heat during operation, in contrast to the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a cooking device that can both dissipate heat from electrical components that generate heat during operation and dry the inside of the water tank.

[0006] The third technical problem to be solved by the present invention is to provide a cooking device that can both dissipate heat from electrical components that generate heat during operation and dry the inside of the water tank, and can automatically switch between the two as water is added.

[0007] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cooking device, including an inner pot;

[0008] An exhaust channel is located above the aforementioned inner liner and has an air inlet;

[0009] Electrical components are located outside the inner liner and generate heat during operation.

[0010] Its characteristic is that it further includes:

[0011] An air duct is provided outside the inner liner and has a first air duct and a second air duct. The first air duct is opposite to the electrical components mentioned above, while the second air duct is in fluid communication with the air inlet of the exhaust channel mentioned above.

[0012] An air guide fan is located in the aforementioned air guide duct and is used to drive the airflow from the first air guide port to the second air guide port.

[0013] Furthermore, a heating plate is installed on the bottom wall of the inner liner, and the aforementioned electrical component is a power supply board.

[0014] It also includes a water tank assembly, which includes a water tank base extending forward and backward and a water tank housed in the water tank base, wherein the front end of the water tank base is open to form a water tank opening with the water tank extending forward.

[0015] The aforementioned air guide fan is configured to operate as follows: In the initial state, when the heating plate is working, the power board temperature rises. The air guide fan, located in the air duct, dissipates heat from the power board and removes excess gas from the inner pot during cooking. When water is added, the heating plate is not working, so the power board does not heat up and there is no need to dissipate heat. The air guide fan is located in the water tank and its exhaust is in fluid communication with the second air vent. This allows the air guide fan to remove moisture from the water tank, drying the inside of the water tank and preventing excessive humidity that could lead to bacterial growth.

[0016] Furthermore, the air guide duct is located above the water tank base. The bottom wall of the air guide duct and the top wall of the water tank base are respectively open, with the two openings facing each other vertically through the interior of the air guide duct and the water tank base, forming a lifting channel for the air guide fan to move up and down.

[0017] Furthermore, in the initial state, when the water tank is moved out of the water tank base, the aforementioned air guide fan descends through the aforementioned lifting channel and is located in the aforementioned water tank base;

[0018] With water added, the water tank is moved into the water tank seat, and the aforementioned air guide fan rises from the water tank seat through the aforementioned lifting channel and is positioned in the aforementioned air guide duct. This lifting and connecting mechanism allows the air guide fan to move between the air guide duct and the interior of the water tank seat. Simultaneously, the lifting channel connects the air guide duct and the interior of the water tank seat, allowing moisture to be smoothly exhausted through the air guide duct and exhaust channel when the air guide fan is drying the interior of the water tank seat.

[0019] Furthermore, it also includes a transmission component that is movably mounted in the aforementioned water tank base and linked to the aforementioned air guide fan.

[0020] In the initial state, the aforementioned transmission component is supported on the top surface of the water tank and is at its upper limit. The water tank moves out of the water tank seat, and the aforementioned transmission component falls under its own gravity, driving the aforementioned air guide fan to descend until the transmission component abuts against the inner bottom surface of the water tank seat and is at its lower limit, and the aforementioned air guide fan is located in the water tank seat, thus achieving the aforementioned water filling state. In this way, the water tank moves out of the water tank seat, causing the transmission component to fall, and the air guide fan descends through the lifting channel and air guide duct into the water tank seat.

[0021] When water is being added, the water tank moves into the water tank seat, pushing the aforementioned transmission component. The transmission component rises, causing the air guide fan to rise until it reaches the top surface of the water tank and is capped. The air guide fan is then positioned within the air guide duct, achieving the initial state described above. In this way, the water tank moves into the water tank seat, driving the transmission component, which in turn drives the air guide fan, causing it to rise from the water tank seat into the air guide duct via the lifting channel.

[0022] Furthermore, the transmission component is a plate extending horizontally and vertically, and its upper end is rotatably connected to the left and right sidewalls of the water tank base via a rotating shaft extending horizontally. The aforementioned air guide fan is arranged horizontally, and its lower end always abuts against the lower end of the aforementioned transmission component. This allows the lower end of the aforementioned transmission component to drive the aforementioned air guide fan to slide vertically along the height direction of the aforementioned lifting channel during rotation around the aforementioned rotating shaft.

[0023] Furthermore, in the initial state, the aforementioned transmission component extends horizontally and rests on the top surface of the water tank. The water tank is moved out of the water tank base, and the lower end of the transmission component rotates downwards around the aforementioned pivot until it abuts against the inner bottom surface of the water tank base, thus achieving the water filling state. In this way, the up-and-down rotation of the lower end of the transmission component around the pivot drives the air guide fan to slide up and down along the lifting channel, thereby realizing the up-and-down movement of the air guide fan between the air guide duct and the inside of the water tank base.

[0024] Furthermore, when water is added, the transmission component is tilted backward from top to bottom. This allows the transmission component to work more effectively when the water tank is moved into the tank seat, enabling the lower end of the transmission component to rotate upward and drive the air guide fan upward.

[0025] Furthermore, the air guide fan includes a fan body and a fan bracket for mounting the fan body. A transmission block protrudes from the lower end of the fan bracket, and this transmission block always abuts against the lower end of the aforementioned transmission component. Sliding rods extending laterally protruding from both the left and right ends of the fan bracket are respectively provided. Upper sliding grooves are respectively formed on the left and right sidewalls of the air guide duct at the corresponding locations of the lifting channel, and lower sliding grooves are respectively formed on the left and right sidewalls of the water tank base at the corresponding locations of the lifting channel. Each lower sliding groove is vertically aligned with and communicates with the corresponding upper sliding groove, allowing the corresponding sliding rod to be inserted and guided vertically. This enables the transmission component to better drive the air guide fan, and allows the air guide fan to move vertically more effectively under the drive of the transmission component.

[0026] Furthermore, the lower end of the transmission component has left and right extending guide rods protruding from its left and right sides, respectively, while the left and right side walls of the water tank base are respectively provided with guide grooves for the corresponding guide rods to be inserted and guided to slide, and the shape of each guide groove is an arc centered on the aforementioned rotating shaft. In this way, the cooperation between the guide rods and the guide grooves enables the lower end of the transmission component to rotate more smoothly up and down, thereby smoothly driving the air guide fan to move up and down.

[0027] Furthermore, the transmission component has a vent that matches the size of the aforementioned air guide fan, and when water is added, the vent is opposite to the aforementioned air guide duct. This helps to ensure the air intake of the air guide fan (air enters from the water tank opening of the water tank base through the aforementioned vent), thereby ensuring the drying effect inside the water tank base.

[0028] Furthermore, an upper mounting plate is horizontally arranged above the inner liner, and an air guide cover is provided on the upper mounting plate to form the exhaust channel. The water tank assembly, air guide duct and electrical components are all arranged on the upper surface of the upper mounting plate and located on the same side of the exhaust channel.

[0029] Compared with the prior art, the advantages of this invention are as follows: a guide fan is provided in the air duct, and the first air vent of the air duct is opposite to the electrical components, while the second air vent is fluidly connected to the air inlet of the exhaust channel. In operation, the guide fan rotates, creating a negative pressure at the first air vent. The outside cold air mixes with the hot air around the electrical components and enters the air duct through the first air vent. Then, it enters the exhaust channel through the second air vent and is discharged together with the gas discharged from the inner liner into the exhaust channel. This simultaneously achieves heat dissipation for the electrical components and exhaust of the inner liner, resulting in a compact structure. Attached Figure Description

[0037] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0038] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this invention can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. 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.

[0039] like Figures 1-7 As shown, a cooking device includes an inner pot 1 with a front opening, an exhaust channel 2, an electrical component 4, an air duct 3, and a fan 5. The exhaust channel 2 is disposed above the inner pot 1 and has an air inlet 21, while the electrical component 4 is disposed outside the inner pot 1 and generates heat during operation. The air duct 3 is disposed outside the inner pot 1 and has a first air inlet 31 and a second air inlet 32. The first air inlet 31 is opposite to the electrical component 4, while the second air inlet 32 ​​is in fluid communication with the air inlet 21 of the exhaust channel 2 (in this embodiment, the two overlap, e.g., ...). Figure 1(As shown). Furthermore, the aforementioned air guide fan 5 is located in the aforementioned air guide duct 3 and is used to drive the airflow from the first air guide port 31 to the second air guide port 32.

[0040] As can be seen from the above, the air duct 3 of this invention is equipped with an air guide fan 5, and the first air guide port 31 of the air guide duct 3 is opposite to the electrical component 4, while the second air guide port 32 is fluidly connected to the air inlet 21 of the exhaust channel 2. In the working state, the air guide fan 5 rotates and forms a negative pressure at the first air guide port 31. The outside cold air mixes with the hot air around the electrical component 4 and enters the air guide duct 3 through the first air guide port. Then, it enters the exhaust channel 2 through the second air guide port 32 and is discharged together with the gas discharged from the inner liner 1 into the exhaust channel 2. The air guide fan 5 simultaneously achieves heat dissipation for the electrical component 4 and exhaust for the inner liner 1, resulting in a compact structure.

[0041] Furthermore, a heating plate 11 is installed on the bottom wall of the inner liner 1, and the electrical component 4 is a power supply board. When the heating plate 11 is working, a large amount of current flows through the power supply board, causing a temperature rise. When the heating plate 11 is not working, no current flows through the power supply board. Further, a water tank assembly 6 is also included. This water tank assembly 6 includes a water tank base 61 extending forward and backward, and a water tank 62 housed in the water tank base 61. The front end of the water tank base 61 is open to form a water tank opening 610 for the water tank 62 to extend forward. The aforementioned air guide fan 5 is set to operate. In the initial state, when the heating plate 11 is working, the power board temperature rises. The air guide fan 5 is located in the air guide duct 3 to dissipate heat from the power board and exhaust excess gas from the inner pot 1 during cooking. When water is added, the heating plate 11 is not working, so the power board does not heat up and there is no need to dissipate heat from the power board. The air guide fan 5 is located in the water tank seat 61, and the air outlet of the air guide fan 5 is in fluid communication with the second air vent 32. In this way, the air guide fan 5 removes moisture from the water tank seat 61, achieving dryness inside the water tank seat 61 and preventing excessive humidity inside the water tank seat 61 from causing bacterial growth.

[0042] Furthermore, the aforementioned air duct 3 is located above the aforementioned water tank base 61. The bottom wall of the air duct 3 and the top wall of the water tank base 61 are respectively open, with the two openings vertically aligned and extending through the interior of the air duct 3 and the water tank base 61, forming a lifting channel 7 for the aforementioned air guide fan 5 to move up and down. In the initial state, when the water tank 62 is removed from the water tank base 61, the aforementioned air guide fan 5 descends through the lifting channel 7 and is located within the water tank base 61. When water is added, when the water tank 62 is moved into the water tank base 61, the aforementioned air guide fan 5 rises from the water tank base 61 through the lifting channel 7 and is located within the air duct 3. This lifting and connecting mechanism allows the air guide fan 5 to move between the air duct 3 and the interior of the water tank base 61. Simultaneously, the lifting channel 7 connects the air duct 3 and the interior of the water tank base 61, allowing moisture to be smoothly discharged through the air duct 3 and the exhaust channel 2 when the air guide fan 5 is drying the interior of the water tank base 61.

[0043] Furthermore, it also includes a transmission component 8 that is movably disposed in the water tank base 61 and linked to the air guide fan. In the initial state, the transmission component 8 is supported on the top surface of the water tank 62 and is at its upper limit. The water tank 62 moves out of the water tank base 61, and the transmission component 8 falls under its own weight, causing the air guide fan to descend until the transmission component 8 abuts against the inner bottom surface of the water tank base 61 and is at its lower limit, thus placing the air guide fan 5 in the water tank base 61 and achieving the water filling state. In this way, the water tank 62 moves out of the water tank base 61, causing the transmission component 8 to fall, and the air guide fan 5 descends through the lifting channel 7 and the air guide duct 3 into the water tank base 61. In the water filling state, the water tank 62 moves into the water tank base 61, pushing the transmission component 8. The transmission component 8 rises, causing the air guide fan to rise until the transmission component 8 rises to the top surface of the water tank 62 and is at its upper limit, while the air guide fan 5 is placed in the air guide duct 3, achieving the initial state. In this way, the water tank 62 moves into the water tank seat 61, which drives the transmission component 8. The transmission component 8 drives the air guide fan 5, which then rises from the water tank seat 61 into the air guide duct 3 through the lifting channel 7.

[0044] Specifically, in this embodiment, the transmission component 8 is a plate extending horizontally and vertically. The upper end of the transmission component 8 is rotatably connected to the left and right sidewalls of the water tank base 61 via a horizontally extending pivot 81. The air guide fan 5 is positioned horizontally, and its lower end always abuts against the lower end of the transmission component 8. This allows the lower end of the transmission component 8 to rotate around the pivot 81, driving the air guide fan 5 to slide vertically along the height of the lifting channel 7. Initially, the transmission component 8 extends horizontally and rests on the top surface of the water tank 62. The water tank 62 is removed from the water tank base 61, and the lower end of the transmission component 8 rotates downwards around the pivot 81 until it abuts against the inner bottom surface of the water tank base 61, thus filling the tank with water. In this way, the vertical rotation of the lower end of the transmission component 8 around the pivot 81 drives the air guide fan 5 to slide vertically along the lifting channel 7, thereby achieving vertical movement of the air guide fan 5 between the air guide duct 3 and the water tank base 61. Preferably, when water is added, the transmission component 8 is tilted backward from top to bottom. This allows the water tank 62 to better act on the transmission component 8 when it is moved into the water tank seat 61, enabling the lower end of the transmission component 8 to rotate upward more effectively and drive the air guide fan 5 to rise.

[0045] Furthermore, the aforementioned air guide fan 5 includes a fan body 51 and a fan bracket 52 for mounting the fan body 51. A transmission block 522 protrudes from the lower end of the fan bracket 52, and this transmission block 522 always abuts against the lower end of the aforementioned transmission component 8. Sliding rods 521 extending laterally protruding from the left and right ends of the fan bracket 52 are respectively provided. Upper sliding grooves 33 are respectively opened on the left and right sidewalls of the aforementioned air guide duct 3 at the corresponding locations of the aforementioned lifting channel 7. Lower sliding grooves 611 are respectively opened on the left and right sidewalls of the water tank base 61 at the corresponding locations of the aforementioned lifting channel 7. Each lower sliding groove 611 is vertically aligned with and communicates with the corresponding upper sliding groove 33, allowing the corresponding sliding rod 521 to be inserted and guided vertically. This enables the transmission component 8 to better drive the air guide fan 5, and allows the air guide fan 5 to move vertically more effectively under the drive of the transmission component 8.

[0046] Preferably, the lower end of the transmission component 8 is provided with left and right extending guide rods 82 on its left and right sides, and the left and right side walls of the water tank base 61 are respectively provided with guide grooves 612 for the corresponding guide rods 82 to be inserted and guided to slide, and the shape of each guide groove 612 is an arc centered on the rotating shaft 81. In this way, the cooperation between the guide rods 82 and the guide grooves 612 enables the lower end of the transmission component 8 to rotate more smoothly up and down, thereby driving the air guide fan 5 to move up and down smoothly. In addition, the transmission component 8 is provided with a vent 80 that matches the size of the air guide fan 5, and when water is added, the vent 80 is opposite to the air guide duct. This helps to ensure the air intake of the air guide fan 5 (air intake from the water tank opening 610 of the water tank base 61 through the vent 80), thereby ensuring the drying effect inside the water tank base 61.

[0047] In addition, in this embodiment, an upper mounting plate 9 is horizontally arranged above the inner liner 1. The upper mounting plate 9 is covered with a wind guide hood 20 to form the exhaust channel 2. The water tank assembly 6, the wind guide duct 3 and the electrical components 4 are all arranged on the upper surface of the upper mounting plate 9 and are located on the same side of the exhaust channel 2.

[0048] The term "fluid connectivity" as used in this invention refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, 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 part and the second part, or an indirect connection between the first part and the second part 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.
