Description

Technical Field

[0001] This invention relates to the field of household appliances, and more particularly to a cooking device with a steaming function. Background Technology

[0002] Steam ovens, steam cookers, and other cooking appliances with steaming functions use steam to heat food placed inside the inner pot. 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 pot. During cooking, water from the water tank is introduced into the inner pot, and the heating plate heats the water to produce steam. Examples include Chinese utility model patent ZL202120331807.9 (authorization announcement number CN217218730U) and Chinese invention patent ZL202010620846.0 (authorization announcement number CN111820728A). Furthermore, when the heating plate is working, current continuously flows through the relay, causing a higher temperature rise in the power board. When the heating plate stops working, no current flows through the relay, and the temperature rise in the power board is generally not very high. Therefore, when the heating plate is working, the power board needs to be cooled to prevent it from overheating and affecting the normal operation of the cooking equipment. When the heating plate is not working, there is no need to cool the power board.

[0003] Furthermore, the water tank assembly of cooking equipment generally includes 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 interior of the water tank base, which is difficult to clean, especially for rectangular, top-mounted bases. The constantly damp environment inside the water tank base can easily lead to bacterial growth, thus jeopardizing cooking safety. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a cooking device with a steaming function that can dissipate heat from a first electrical component, in contrast to the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a cooking device with steaming function that can dry the inside of the water tank base, in contrast to the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a cooking device with steaming function that can both dissipate heat from the first electrical component and dry the inside of the water tank base, in contrast to the prior art.

[0007] The fourth technical problem to be solved by the present invention is to provide a cooking device with steaming function that can both dissipate heat from the first electrical component and dry the inside of the water tank, and can automatically switch between the two as water is added.

[0008] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cooking device with a steaming function, comprising:

[0009] The inner liner has a heating plate installed on the bottom wall;

[0010] The water tank assembly extends beyond the inner liner in the front-rear direction and includes a water tank seat with a front opening and a water tank housed in the water tank seat and extending through the front port of the water tank seat.

[0011] The first electrical component is located outside the inner liner and generates heat when the heating plate is in operation.

[0012] Its characteristic is that it further includes:

[0013] The heat dissipation channel includes a heat dissipation air inlet and a heat dissipation air outlet that communicate with the outside, and the heat dissipation air outlet can be connected to one of the phase flows in the water tank base or the flow field where the first electrical component is located.

[0014] Furthermore, in the initial state, the heating plate is working, and the heat dissipation vent is in fluid communication with the flow field where the first electrical component is located. However, in the water-filling state, the heating plate is not working, the water tank extends out from the front opening of the water tank base, and the heat dissipation vent is in fluid communication with the interior of the water tank base.

[0015] Furthermore, it also includes an air guide channel and a control unit with movable settings. The air guide channel has an air inlet, a first air outlet, and a second air outlet. The air inlet is fluidly connected to the aforementioned heat dissipation outlet, the first air outlet is connected to the interior of the water tank, and the second air outlet is fluidly connected to the flow field where the first electrical component is located. In the initial state, the control unit closes the first air outlet and opens the second air outlet, with the air inlet connected to the second air outlet. In the water-filling state, the control unit opens the first air outlet and closes the second air outlet, with the air inlet connected to the first air outlet. By opening and closing the first and second air outlets through the control unit, the air inlet is connected to one of the air outlets, thereby achieving fluid communication between the heat dissipation outlet of the heat dissipation channel and either the first or second air outlet, achieving drying of the interior of the water tank (in the water-filling state) or heat dissipation of the first electrical component (in the initial state).

[0016] Furthermore, the rear opening of the water tank base coincides with the aforementioned first air guide outlet, and the first air guide outlet is located between the air guide inlet and the second air guide outlet.

[0017] The aforementioned control component is a vertically arranged baffle, the middle of which is rotatably mounted on the rear port of the aforementioned water tank base via a vertically extending pivot.

[0018] It also includes a rebound device located at the rear of the water tank base. The output shaft of this rebound device extends in the front-to-back direction and is fixed to the baffle, and is located on one side of the aforementioned rotating shaft.

[0019] In the initial state, the baffle covers the rear port of the water tank seat. Pressing the front of the water tank backward causes the water tank to move backward and trigger the rebound device through the baffle. The rebound device releases elastic force, causing the baffle to rotate outward relative to the water tank seat and into the air guide channel with the rotating shaft as the center. The baffle opens the rear port of the water tank seat and is positioned between the first and second air guide outlets of the air guide channel. The air guide inlet is connected to the first air guide outlet. At the same time, the water tank is pushed forward, causing it to extend from the front port of the water tank seat, thus entering the water filling state. In this way, the heat dissipation channel dries the inside of the water tank seat through the air guide channel.

[0020] When the water tank is pushed into the water tank seat, the water tank pushes the baffle and causes the baffle to rotate inward relative to the water tank seat around the aforementioned pivot, thereby closing the rear port of the water tank seat. The air inlet and the first air outlet are reconnected, and the heat dissipation channel dissipates heat to the first electrical component through the air channel. At the same time, the aforementioned rebound device is compressed and accumulates elastic force, which on the one hand enables the baffle to stably cover the rear end of the water tank seat, and on the other hand facilitates the next water filling operation.

[0021] Furthermore, the rotating shaft is offset from the vertical centerline of the aforementioned baffle, while the output shaft of the aforementioned rebound device is fixed to the side of the baffle with a smaller width. This allows for a larger cross-section of the air guide channel (the area of ​​the baffle portion within the air guide channel is larger when water is added), thereby improving the drying efficiency inside the water tank and the heat dissipation efficiency of the first electrical component. On the other hand, when water is added, less of the baffle is screwed into the water tank, allowing the water tank to push the baffle more smoothly when it is pushed into the tank after water is added.

[0022] Furthermore, an exhaust channel is provided above the inner liner, and this exhaust channel has an exhaust fan. The exhaust fan's outlet air is fluidly connected to the heat dissipation air inlet of the aforementioned heat dissipation channel. On the one hand, using the exhaust fan to drive outside cold air into the heat dissipation channel can improve the drying effect inside the water tank seat and the heat dissipation efficiency of the first electrical component; on the other hand, there is no need for a separate fan, as the exhaust fan can simultaneously drive the external exhaust flow in the exhaust channel and the heat dissipation airflow in the heat dissipation channel.

[0023] Furthermore, the water tank assembly and the heat dissipation channel are both located on the inner liner and on the same side of the exhaust channel. The exhaust fan includes a centrifugal fan mounted on the air inlet of the exhaust channel, and a vent is provided on one side wall of the air inlet end of the exhaust channel, which is in fluid communication with the heat dissipation air inlet of the heat dissipation channel. This allows the cooking equipment with steaming function to have a compact internal structure, facilitating the simultaneous entry of exhaust fan air into both the exhaust channel and the heat dissipation channel.

[0024] Furthermore, a guide plate is vertically arranged in the left-right direction on the front side of the aforementioned centrifugal fan in the exhaust channel to guide part of the centrifugal fan's exhaust air into the heat dissipation channel. The guide plate effectively directs part of the centrifugal fan's exhaust air into the heat dissipation channel, ensuring reliable drying of the water tank interior and heat dissipation of the first electrical component.

[0025] Furthermore, the heat dissipation channel is composed of a heat dissipation pipe arranged horizontally in the left-right direction. One end of the heat dissipation pipe forms the aforementioned heat dissipation air inlet and is inserted into the ventilation opening of the aforementioned exhaust channel. The front edge of the pipe inlet extends outward in the left-right direction to form the aforementioned guide plate. This facilitates the smooth flow of air into the heat dissipation channel through the ventilation opening and also facilitates the placement of the guide plate at the ventilation opening.

[0026] Furthermore, the air guide channel and the first electrical component are both located on the inner liner, and are situated on the same side of the exhaust channel as the aforementioned water tank assembly and heat dissipation channel. The air guide channel is located on one side of the heat dissipation channel, while the first electrical component is located on one side of the air guide channel, opposite to the second air outlet of the air guide channel. This allows for a more compact internal structure of the cooking equipment with steaming function, smoother communication between the air guide channel and the heat dissipation channel, and better removal of heat from the second air outlet, thus improving the heat dissipation effect on the first electrical component.

[0027] Furthermore, the heat dissipation outlet of the heat dissipation channel coincides with the air inlet of the air guide channel. This allows for better connection between the heat dissipation channel and the air guide channel.

[0028] Furthermore, the heat dissipation channel and the air guide channel are integrated into one piece and located on the rear side of the aforementioned water tank assembly. This simplifies the structure of the heat dissipation channel and the air guide channel and completely prevents gas leakage at their connection point.

[0029] Furthermore, the heat dissipation channel, air guide channel, and water tank base are integrated into one unit. This makes the internal structure of the cooking equipment with steaming function simpler, completely avoids gas leakage, and improves the drying effect inside the water tank base and the heat dissipation effect on the first electrical component.

[0030] Compared with the prior art, the advantages of the present invention are as follows: The present invention heats the water entering the inner pot through a heating plate at the bottom of the inner pot, thereby generating steam required for cooking. When water is added to the water tank (i.e., when the water tank is removed from the front port of the water tank seat), the heating plate stops working (if the heating plate continues to work without water input, it will overheat). Furthermore, when the heating plate is working, the first electrical component generates heat, and when the heating plate is not working, the first electrical component does not generate heat.

[0031] Furthermore, a heat dissipation channel is provided, and the heat dissipation outlet of this channel can be connected to one of the phase flows in the water tank base or the flow field where the first electrical component is located. In the initial state (when the heating plate is operating), the heat dissipation outlet is connected to the flow field where the first electrical component is located, thereby dissipating heat from the first electrical component through the heat dissipation channel and preventing the operating environment temperature of the first electrical component from becoming too high and affecting its performance. When water is added, the water tank extends from the front opening of the water tank base, and the heat dissipation outlet is connected to the internal phase flow of the water tank base, thereby drying the inside of the water tank base and preventing excessive humidity that could lead to bacterial growth.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0041] 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.

[0042] like Figures 1-8 As shown, a cooking device with a steaming function includes an inner pot 1, a heating plate 2 mounted on the bottom wall of the inner pot 1, and a water tank assembly 3 disposed outside the inner pot 1. The water tank assembly 3 is arranged along the front-to-back direction and includes a water tank seat 31 with a front opening and a water tank 32 housed in the water tank seat 31 and extending through the front port of the water tank seat 31. In this invention, both the water tank seat 31 and the water tank 32 are elongated box structures, such as... Figure 1 As shown.

[0043] Furthermore, in addition to the inner liner 1, a first electrical component 4 and a heat dissipation channel 5 are also provided. When the heating plate 2 is in operation, the first electrical component 4 generates heat. The heat dissipation channel 5 includes a heat dissipation air inlet 51 and a heat dissipation air outlet 52 that communicate with the outside. The heat dissipation air outlet 52 can be in fluid communication with either the interior of the water tank base 31 or one of the phase flows in the flow field where the first electrical component 4 is located. In the initial state, when the heating plate 2 is in operation, the heat dissipation air outlet 52 is in fluid communication with the flow field where the first electrical component 4 is located, such as... Figures 1-6 As shown; when water is added, the heating plate 2 is not working, the water tank 32 extends from the front opening of the water tank base 31, and the heat dissipation vent 52 is in fluid communication with the interior of the water tank base 31, as shown. Figure 7 and Figure 8 As shown.

[0044] This invention uses a heating plate 2 at the bottom of the inner tank 1 to allow water to enter, thereby generating steam for cooking. When water is added to the water tank 32 (i.e., when the water tank 32 is removed from the front port of the water tank base 31), the heating plate 2 stops working (if the heating plate 2 continues to work without water input, it will overheat). Furthermore, when the heating plate 2 is working, the first electrical component 4 generates heat; when the heating plate 2 is not working, the first electrical component 4 does not generate heat. Further, a heat dissipation channel 5 is provided, and the heat dissipation outlet 52 of this channel 5 can be fluidly connected to either the interior of the water tank base 31 or one of the phase flows in the flow field where the first electrical component 4 is located. In the initial state (when the heating plate 2 is working), the heat dissipation outlet 52 is fluidly connected to the flow field where the first electrical component 4 is located, thereby dissipating heat from the first electrical component 4 through the heat dissipation channel 5, preventing the operating environment temperature of the first electrical component 4 from becoming too high and affecting its performance. When water is added, the water tank 32 extends from the front opening of the water tank base 31, and the heat dissipation vent 52 is in fluid communication with the interior of the water tank base 31, thereby drying the interior of the water tank base 31 and preventing excessive humidity that could lead to bacterial growth. Specifically, in this embodiment, the first electrical component 4 is a power board. When the heating plate 2 is working, a large current flows through the power board, generating heat.

[0045] Furthermore, it also includes an air guide channel 6 and a movable control component. The air guide channel 6 has an air inlet 61, a first air outlet 62, and a second air outlet 63. The air inlet 61 is in fluid communication with the aforementioned heat dissipation outlet 52, the first air outlet 62 is in communication with the interior of the aforementioned water tank base 31, and the second air outlet 63 is in fluid communication with the flow field where the aforementioned first electrical component 4 is located. In the initial state, the control component closes the first air outlet 62 and opens the second air outlet 63, and the air inlet 61 is in communication with the second air outlet 63. Figure 4 As shown; when water is added, the aforementioned control unit opens the first air outlet 62 and closes the second air outlet 63, and the aforementioned air inlet 61 is connected to the first air outlet 62, as shown. Figure 8 As shown. The first air outlet 62 and the second air outlet 63 are opened and closed by the control unit, so that the air inlet 61 is connected to one of the air outlets, thereby realizing the heat dissipation outlet 52 of the heat dissipation channel 5 is connected to one of the first air outlet 62 or the second air outlet 63, so as to achieve drying of the inside of the water tank base 31 (in the water-filled state) or heat dissipation of the first electrical component 4 (in the initial state).

[0046] Furthermore, specifically, in this embodiment, the rear opening of the aforementioned water tank base 31 coincides with the aforementioned first air outlet 62 (e.g., Figure 8As shown in the figure, the air guide channel 6 extends in the left-right direction, and the first air guide outlet 62 is located between the air guide inlet 61 and the second air guide outlet 63. The control component is a vertically arranged baffle 7, the middle of which is rotatably mounted on the rear port of the water tank base 31 via a vertically extending pivot (not shown). A rebound device 71 is also included on the rear side of the water tank base 31. The output shaft of the rebound device 71 extends in the front-back direction and is fixed to the baffle 7, and is located on one side of the pivot. In this embodiment, the rebound device 71 is specifically a rebounder.

[0047] Furthermore, such as Figure 4 As shown, in the initial state, the baffle 7 covers the rear port of the water tank base 31 in the left-right direction. The air inlet 61 is connected to the second air outlet 63, and the heat dissipation channel 5 dissipates heat to the first electrical component 4 through the air outlet 6. In the initial state, pressing the front of the water tank 32 backward causes the water tank 32 to move backward and trigger the rebound device 71 through the baffle 7. The rebound device 71 releases elastic force, causing the baffle 7 to rotate outward relative to the water tank base 31 into the air outlet 6 with the aforementioned pivot as the center. The baffle 7 opens the rear port of the water tank base 31 and is positioned between the first air outlet 62 and the second air outlet 63 of the air outlet 6. The air inlet 61 is connected to the first air outlet 62. At the same time, pushing the water tank 32 forward causes the water tank 32 to extend from the front port of the water tank base 31, thus entering the water filling state. At this time, the heat dissipation channel 5 dries the inside of the water tank base 31 through the air outlet 6. When the water tank 32 is filled with water and pushed into the water tank seat 31, the water tank 32 pushes the baffle 7, causing the baffle 7 to rotate inward relative to the water tank seat 31 around the aforementioned pivot, thus closing the rear port of the water tank seat 31. The air inlet 61 and the first air outlet 62 are reconnected. The heat dissipation channel 5 dissipates heat from the first electrical component 4 through the air outlet 6. At the same time, the aforementioned rebound device 71 is compressed and accumulates elastic force, which on the one hand allows the baffle 7 to stably cover the rear end of the water tank seat 31, and on the other hand facilitates the next water filling operation. Preferably, in this embodiment, the width of the baffle 7 in the left-right direction is greater than that of the second air outlet 63. When the second air outlet 63 is closed, the left end of the baffle 7 abuts against the left edge of the second air outlet 63, thereby limiting the position of the baffle 7.

[0048] Furthermore, preferably, the aforementioned rotating shaft is offset from the vertical centerline of the aforementioned baffle 7, and the output shaft of the aforementioned rebound device 71 is fixed to the side of the baffle 7 with a smaller width. This allows for a larger cross-section of the air guide channel 6 (the area of ​​the baffle 7 portion disposed in the air guide channel 6 is larger when water is added), thereby improving the drying efficiency inside the water tank seat 31 and the heat dissipation efficiency of the first electrical component 4; on the other hand, when water is added, less of the baffle 7 is screwed into the water tank seat 31, so when water is added and pushed into the water tank 32, the water tank 32 can push the baffle 7 more smoothly.

[0049] Furthermore, in this embodiment, an upper mounting plate 11 is horizontally arranged above the inner liner 1. An exhaust channel 9 is provided on the upper surface of the upper mounting plate 11. The exhaust channel 9 has an exhaust fan. The gas in the inner liner 1 is discharged through the exhaust channel 9 under the drive of the exhaust fan. At the same time, the air outlet of the exhaust fan is fluidly connected to the heat dissipation air inlet 51 of the heat dissipation channel 5. On the one hand, the exhaust fan drives the outside cold air into the heat dissipation channel 5, which can improve the drying effect inside the water tank seat 31 and the heat dissipation efficiency of the first electrical component 4. On the other hand, there is no need to install a separate fan. The exhaust fan can simultaneously drive the external exhaust flow in the exhaust channel 9 and the heat dissipation airflow in the heat dissipation channel 5.

[0050] Furthermore, the aforementioned water tank assembly 3 and heat dissipation channel 5 are both disposed on the upper surface of the aforementioned upper mounting plate 11 and located on the same side of the aforementioned exhaust channel 9. The aforementioned exhaust fan includes a centrifugal fan 8 disposed at the air inlet of the exhaust channel 9, and a vent 91 is provided on one side wall of the air inlet end of the exhaust channel 9, which is in fluid communication with the heat dissipation air inlet 51 of the aforementioned heat dissipation channel 5. This allows for a compact internal structure of the cooking equipment with steaming function, facilitating the simultaneous entry of exhaust fan air into both the exhaust channel 9 and the heat dissipation channel 5.

[0051] Preferably, the exhaust channel 9 is provided with a guide plate 10 vertically along the left-right direction on the front side of the centrifugal fan 8 to guide part of the airflow from the centrifugal fan 8 into the heat dissipation channel 5. The guide plate 10 effectively guides part of the airflow from the centrifugal fan 8 into the heat dissipation channel 5, ensuring reliable drying of the water tank 31 and heat dissipation of the first electrical component 4. Specifically, in this embodiment, the heat dissipation channel 5 is composed of a heat dissipation pipe arranged horizontally along the left-right direction. One end of the heat dissipation pipe forms the heat dissipation air inlet 51 and is inserted into the ventilation opening 91 of the exhaust channel 9. The front edge of the pipe opening extends outward along the left-right direction to form the guide plate 10. This facilitates smooth airflow into the heat dissipation channel 5 through the ventilation opening 91 and also facilitates the placement of the guide plate 10 at the ventilation opening 91.

[0052] Furthermore, the aforementioned air guide channel 6 and the first electrical component 4 are also mounted on the inner liner 1, and are located on the same side of the exhaust channel 9 as the aforementioned water tank assembly 3 and heat dissipation channel 5. The air guide channel 6 is located on one side of the heat dissipation channel 5, while the first electrical component 4 is located on one side of the air guide channel 6, and is positioned opposite to the second air outlet 63 of the air guide channel 6. This allows for a more compact internal structure of the cooking equipment with steaming function, smoother communication between the air guide channel 6 and the heat dissipation channel 5, and better removal of heat from the second air outlet 63, thus improving the heat dissipation effect on the first electrical component 4.

[0053] Furthermore, preferably, the heat dissipation outlet 52 of the aforementioned heat dissipation channel 5 coincides with the air inlet 61 of the air guide channel 6, thereby enabling better connection between the heat dissipation channel 5 and the air guide channel 6. Further preferably, the aforementioned heat dissipation channel 5 and air guide channel 6 are an integral piece and located on the rear side of the aforementioned water tank assembly 3. This simplifies the structure of the heat dissipation channel 5 and air guide channel 6 and completely prevents gas leakage at their connection point. Even more preferably, the aforementioned heat dissipation channel 5, air guide channel 6 (i.e., the air guide channel 6 is also formed by the inner cavity of the pipe body), and water tank base 31 are an integral piece. This simplifies the internal structure of the cooking equipment with steaming function, completely prevents gas leakage, and improves the drying effect inside the water tank base 31 and the heat dissipation effect on the first electrical component 4.

[0054] 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.
