Description

Technical Field

[0001] This invention relates to the field of cooking equipment, and more particularly to an inner pot structure and cooking equipment with a steam condensation function. Background Technology

[0002] Steam ovens, steam ovens, and other cooking appliances with steaming functions use high-temperature steam to heat food. Generally, a heating plate is installed on the bottom wall of the inner pot of the cooking appliance. During cooking, water from the water tank is fed into the inner pot, and the heating plate heats the water to generate steam for heating the food. Examples include Chinese invention patents ZL202010324714.3 (authorization announcement number CN113545658B) and ZL 202010620846.0 (authorization announcement number CN111820728B).

[0003] However, after cooking, a large amount of steam remains inside the inner pot. Opening the door at this time will cause a large amount of steam to spray directly at the user, posing a risk of burns. In traditional cooking setups, residual gas is usually expelled through an exhaust duct driven by an exhaust fan. However, this results in a large amount of condensation forming at the exhaust vent, which flows onto the machine's surface, severely impacting the user experience.

[0004] Condensation is the main way to deal with the remaining steam in the inner liner in the prior art to solve the above problems. For example, Chinese invention patent with patent number ZL 201910254524.6 (authorization announcement number CN111759184B) discloses an exhaust structure of a steam cooking device, including a mounting plate, a guide plate, a centrifugal fan and a condensation chamber. The guide plate covers the mounting plate to form an exhaust channel. The centrifugal fan is set in the exhaust channel. The air inlet of the condensation chamber is connected to the cooking chamber of the steam cooking device through a vent pipe. When the centrifugal fan is working, an airflow is formed in its volute cavity. The air outlet of the condensation chamber can be connected to the upstream fluid of the airflow formed in the volute cavity. For example, there are Chinese utility model patents titled "A Steam Condensation Structure and Cooking Device" (patent number ZL202221059553.0, authorization announcement number CN217659340U) and Chinese invention patents titled "A Steamer" (patent number ZL202010324714.3, authorization announcement number CN113545658B). However, existing condensation methods have low condensation efficiency and still cannot effectively solve the problems existing in the prior art. Summary of the Invention

[0005] The first technical problem to be solved by the present invention is to provide an inner liner structure with high condensation efficiency and steam condensation function, which is in contrast to the prior art.

[0006] The second technical problem to be solved by the present invention is to provide an inner liner structure with steam condensation function that has high condensation efficiency and is easy to control, in contrast to the prior art.

[0007] The third technical problem to be solved by the present invention is to provide a cooking device having the above-described inner pot structure, in contrast to the prior art.

[0008] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is: a cooking inner pot structure with steam condensation function, comprising an inner pot with a front opening, characterized in that it further comprises:

[0009] The condensation zone is located on the inner liner and is used to cool the steam inside the inner liner.

[0010] A steam guide fan is used to drive the steam in the inner tank to flow to the condensation zone.

[0011] Furthermore, an exhaust channel with a centrifugal fan is provided above the inner liner. This centrifugal fan and the aforementioned steam guide fan can be linked through a transmission mechanism. In this way, the steam guide fan can be driven without the need for a separate drive device.

[0012] Furthermore, it also includes a control mechanism for controlling the aforementioned transmission mechanism to have at least two states:

[0013] In the first state, the transmission mechanism links the centrifugal fan and the steam guide fan;

[0014] In the second state, the transmission mechanism does not link the centrifugal fan and the steam guide fan. This allows for start-stop control of the steam guide fan. Specifically, during cooking, the transmission mechanism is in the second state, at which point the steam guide fan does not rotate while the centrifugal fan rotates; and when cooking ends, the transmission mechanism is in the first state, at which point both the steam guide fan and the centrifugal fan rotate.

[0015] Furthermore, the transmission mechanism includes a first clutch component linked to the motor shaft of the centrifugal fan and a second clutch component linked to the fan shaft of the steam guide fan.

[0016] In the first state described above, the control mechanism engages the first clutch and the second clutch, causing the centrifugal fan and the steam duct fan to work together.

[0017] In the second state described above, the control mechanism disengages the first clutch from the second clutch, preventing the centrifugal fan and the steam duct fan from operating simultaneously. This allows for better control of the steam duct fan's start and stop.

[0018] Furthermore, the condensation zone includes a condenser tube for heat exchange with the steam in the inner liner, and a water pump for driving water into the condenser tube. This water cooling method condenses the remaining steam in the inner liner. When the water pump is operating, the control mechanism places the transmission mechanism in the first state; when the water pump is not operating, the control mechanism places the transmission mechanism in the second state. That is, during cooking, neither the water pump nor the steam-guiding fan operates; when cooking ends, the water pump operates, and the steam-guiding fan rotates synchronously, achieving sequential start-stop of the water pump and steam-guiding fan, and coordinated operation of the steam-guiding fan and the condensation zone for steam condensation.

[0019] Furthermore, the control mechanism includes a long, narrow control chamber with an inlet and an outlet spaced apart along its length. The inlet is in fluid communication with the outlet of the water pump, while the outlet is in fluid communication with the inlet of the condenser pipe.

[0020] Furthermore, the control room is divided into two parts along its length by a baffle. When the water pump is not operating, the baffle is positioned between the inlet and outlet, preventing water from entering the condenser pipe and thus disabling the condensation zone.

[0021] When the water pump is operating, the baffle moves along the length of the control chamber under the pressure difference on both sides, connecting the inlet and outlet. At this time, water enters the condenser pipe, and the condensation zone begins to operate. Therefore, the opening and closing of the condensation zone can be controlled by controlling the water pump.

[0022] Furthermore, the water inlet is located on the end wall of one end of the control chamber, while a vent is located on the end wall of the other end of the control chamber, communicating with the outside. The water outlet is located on the side wall of the control chamber. In this way, one end of the baffle is subjected to water pressure, while the other end is subjected to atmospheric pressure, allowing the baffle to move more effectively under the pressure difference between the two ends.

[0023] Furthermore, the control mechanism also includes a push rod, one end of which passes through the control chamber along its length and is linked to the stop block, while the other end is located outside the control chamber and is linked to the first clutch component.

[0024] When the water pump is operating, the aforementioned stop block moves, driving the push rod and engaging the first and second clutches. This allows the water pump to more effectively start the steam-guiding fan, thereby enabling better coordination between the steam-guiding fan and the condensate zone.

[0025] Furthermore, one end of the push rod is fixed to the aforementioned stop block and fitted with a return spring, while a spring seat is also provided in the control room, with the return spring sandwiched between the spring seat and the aforementioned stop block.

[0026] With the inlet and outlet connected, the return spring is compressed, causing the stop block to move towards the inlet, thus disconnecting the inlet and outlet. When the pump stops, the stop block quickly resets under the elastic force of the return spring, separating the inlet and outlet. Water stops entering the condenser pipe, the condenser zone stops operating, and the push rod resets under the stop block's influence. This separates the first and second clutches, preventing the steam duct fan and centrifugal fan from interlocking, and the steam duct fan stops rotating.

[0027] Furthermore, it also includes a first drive shaft that is linked to the fan shaft of the aforementioned steam-guiding fan. One end of the first drive shaft is connected to the other end of the aforementioned push rod, while the other end of the first drive shaft is fixed to the aforementioned first clutch. The first drive shaft is positioned along the moving direction of the first clutch and can move back and forth in that direction under the drive of the aforementioned push rod, thereby engaging or disengaging the first clutch with the second clutch. In this way, the first drive shaft can, on the one hand, realize the linkage between the steam-guiding fan and the centrifugal fan, and on the other hand, move under the drive of the push rod to engage or disengage the first clutch with the second clutch, thereby achieving the start-stop control of the steam-guiding fan.

[0028] Furthermore, a first transmission gear is mounted on the fan shaft of the steam-guiding fan, and a guide ridge extending along its length is protruding on the outer surface of one end of the first transmission shaft.

[0029] It also includes a second transmission gear that meshes with the first transmission gear. This second transmission gear is sleeved on the first transmission shaft and is fitted with the guide protrusion through a guide groove located at the edge of its central hole, with the two engaging in a guiding fit. This achieves linkage between the first transmission shaft and the fan shaft, and also enables the first transmission shaft to move smoothly, thereby ensuring the reliability of the clutch control between the first and second clutch components.

[0030] Furthermore, the first clutch is a wheel centered on the first drive shaft, and the second clutch is linked to the motor shaft of the centrifugal fan via a second drive shaft extending along the length of the first drive shaft, and the second clutch is a wheel centered on the second drive shaft.

[0031] The first and second clutch components are positioned opposite each other, and on their opposing wheel end faces, one of them has a protruding guide shaft extending along the length of the first drive shaft, while the other has a concentric arc-shaped guide groove. The guide shaft can be inserted into the guide groove and move along it, abutting against the end of the guide groove to link the first and second clutch components. In this way, when the first and second clutch components are engaged, the transmission mechanism can smoothly transmit the kinetic energy output from the motor shaft to the fan shaft, and when the first drive shaft moves, the first and second clutch components can be smoothly disengaged.

[0032] Furthermore, the second clutch is fixed to one end of the second drive shaft, while a third drive gear is fixed to the other end of the second drive shaft, and a fourth drive gear that meshes with the third drive gear is mounted on the motor shaft of the centrifugal fan. This enables the linkage between the second drive shaft and the motor shaft.

[0033] Furthermore, the condensation zone is located at the rear of the inner liner, while the aforementioned steam guide fan is located at the front and upper part of the inner liner cavity. Since hot steam tends to rise, when the door is opened after cooking, the steam tends to escape forward and upward. This invention, through the above arrangement, effectively guides the steam to the condensation zone, better preventing steam from directly hitting the user when the door is opened.

[0034] Furthermore, the fan shaft of the steam guide fan is vertically inserted through the top wall of the inner liner, and the air inlet of the steam guide fan is directly opposite the opening of the inner liner. This better prevents steam from escaping from the opening of the inner liner when the door is opened after cooking.

[0035] Furthermore, the condensation zone includes a condenser pipe disposed on the rear side wall of the inner tank. The inlet of the condenser pipe is fluidly connected to the outlet of the water tank, while the outlet of the condenser pipe is fluidly connected to the inlet of the water tank. Cold water in the water tank is introduced into the condenser pipe and exchanges heat with the steam in the inner tank, thereby condensing the remaining steam in the inner tank.

[0036] Furthermore, the condenser tubes are arranged on the rear surface of the inner liner in a curved manner along the left-right direction. This allows the cold water in the condenser tubes to fully exchange heat with the steam, improving the condensation effect on the steam.

[0037] The technical solution adopted to further solve the third technical problem mentioned above is: a cooking device, characterized in that it includes a cooking inner pot structure with steam condensation function as described above.

[0038] Compared with existing technologies, the advantages of this invention are as follows: A condensation zone is provided on the inner pot. When cooking is finished, the steam guide fan in the inner pot drives the steam to flow towards the condensation zone, thereby accelerating the condensation efficiency of the remaining steam in the inner pot and improving the condensation effect. This solves the problem of steam directly spraying towards the user when the door is opened after cooking in existing technologies. Furthermore, the steam guide fan's guidance of the steam simultaneously reduces the amount of steam discharged, solving the problem of excessive steam discharge in existing technologies and improving the user experience.

[0048] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0049] 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.

[0050] A cooking appliance, including such Figures 1-9The illustrated inner liner structure with steam condensation function includes an inner liner 1 with a front opening, a condensation zone 2, and a steam guide fan 3. The condensation zone 2 is located on the inner liner 1 and is used to cool the steam inside the inner liner 1. The steam guide fan 3 drives the steam in the inner liner 1 to flow towards the condensation zone 2.

[0051] In this invention, a condensation zone 2 is provided on the inner pot 1. When cooking is finished, the steam guide fan 3 in the inner pot 1 drives steam to flow towards the condensation zone 2, thereby accelerating the condensation efficiency of the remaining steam in the inner pot 1 and improving the condensation effect. This solves the problem of steam directly spraying at the user when the door is opened after cooking in the prior art. In addition, by guiding the steam through the steam guide fan 3, the condensation effect is improved while reducing the amount of steam discharged, solving the problem of excessive steam discharge in the prior art and improving the user experience.

[0052] Preferably, an exhaust channel with a centrifugal fan 4 is provided on the inner liner 1, and the centrifugal fan 4 and the steam guide fan 3 can be linked through a transmission mechanism 5. This eliminates the need for a separate drive device to drive the steam guide fan 3. Specifically, in this embodiment, an upper mounting plate 10 is horizontally provided on the inner liner 1, and a guide plate 70 is provided on the upper surface of the upper mounting plate 10 to form an exhaust channel. Furthermore, the centrifugal fan 4 is installed at the air inlet of the exhaust channel. Figure 2 As shown.

[0053] Furthermore, the aforementioned inner liner structure also includes a control mechanism 6 for controlling the transmission mechanism 5 to have at least two states: in the first state, the transmission mechanism 5 is linked to the centrifugal fan 4 and the steam guide fan 3; in the second state, the transmission mechanism 5 is not linked to the centrifugal fan 4 and the steam guide fan 3; thereby enabling start-stop control of the steam guide fan 3. Specifically, during cooking, the transmission mechanism 5 is in the second state, at which time the steam guide fan 3 does not rotate while the centrifugal fan 4 rotates; and at the end of cooking, the transmission mechanism 5 is in the first state, at which time both the steam guide fan 3 and the centrifugal fan 4 rotate. Further, the transmission mechanism 5 includes a first clutch 51 linked to the motor shaft 40 of the centrifugal fan 4 and a second clutch 52 linked to the fan shaft 31 of the steam guide fan 3. Furthermore, in the first state described above, the control mechanism 6 engages the first clutch 51 and the second clutch 52, causing the centrifugal fan 4 and the steam duct fan 3 to operate in tandem; in the second state described above, the control mechanism 6 disengages the first clutch 51 and the second clutch 52, causing the centrifugal fan 4 and the steam duct fan 3 to operate in tandem. This allows for better control of the start and stop of the steam duct fan 3.

[0054] In this embodiment, preferably, the condensation zone 2 is located on the rear side of the inner liner 1, while the steam guide fan is located on the upper front of the inner cavity of the inner liner 1. Since hot steam tends to rise, when the door is opened after cooking, the steam tends to escape upwards and forwards. This invention, through the above arrangement, effectively guides the steam to the condensation zone 2, better preventing steam from directly spraying onto the user when the door is opened. More preferably, the fan shaft 31 of the steam guide fan is vertically inserted into the top wall of the inner liner 1, and the air inlet of the steam guide fan is directly opposite the opening of the inner liner 1, thereby better preventing steam from escaping from the opening of the inner liner 1 when the door is opened after cooking. Specifically, the condensation zone 2 includes a condenser pipe 21 located on the rear side wall of the inner liner 1. The inlet of the condenser pipe 21 is fluidly connected to the outlet of the water tank 8, and the outlet of the condenser pipe 21 is fluidly connected to the inlet of the water tank. Cold water in the water tank 8 flows into the condenser pipe 21 and exchanges heat with the steam in the inner liner 1, thereby condensing the remaining steam in the inner liner 1. Preferably, the condenser tube 21 is arranged vertically and horizontally on the rear surface of the inner liner 1, while the water tank 8 is located on the lower rear side of the inner liner 1, so that the cold water in the condenser tube 21 can fully exchange heat with the steam, thereby improving the condensation effect of the steam.

[0055] Furthermore, the aforementioned inner liner 1 structure also includes a water pump 7 that drives water into the condenser pipe 21. This water cooling method condenses the remaining steam in the inner liner 1. When the water pump 7 is operating, the control mechanism 6 sets the transmission mechanism 5 to the first state; when the water pump 7 is not operating, the control mechanism 6 sets the transmission mechanism 5 to the second state. That is, during cooking, neither the water pump 7 nor the steam-guiding fan 3 operates. When cooking ends, the water pump 7 operates, and the steam-guiding fan 3 rotates synchronously, achieving the sequential start and stop of the water pump 7 and the steam-guiding fan 3, as well as the coordinated operation of the steam-guiding fan 3 and the condenser zone 2 for steam condensation.

[0056] Furthermore, the aforementioned control mechanism 6 includes an elongated control chamber 610, on which an inlet 6101 and an outlet 6102 are spaced apart along its length. The inlet 6101 is in fluid communication with the outlet of the water pump 7, while the outlet 6102 is in fluid communication with the inlet of the condenser pipe 21.

[0057] Furthermore, a baffle 62 is provided in the control chamber 610 to divide the control chamber 610 into two parts along its length. When the water pump 7 is not working, the baffle 62 is positioned between the inlet 6101 and the outlet 6102. At this time, the condenser pipe 21 does not receive water, and the condensation zone 2 is not working. When the water pump 7 is working, the baffle 62 moves along the length of the control chamber 610 under the pressure difference on both sides, so that the inlet 6101 and the outlet 6102 are connected. At this time, the condenser pipe 21 receives water, and the condensation zone 2 is working. It can be seen that the opening and closing of the condensation zone 2 can be controlled by controlling the opening and closing of the water pump 7. Preferably, the inlet 6101 is opened on the end wall of one end of the control chamber 610, and a vent 63 communicating with the outside is opened on the end wall of the other end of the control chamber 610. The outlet 6102 is opened on the side wall of the control chamber 610. In this way, one end of the stop block 62 is subjected to water pressure, while the other end is subjected to atmospheric pressure, allowing the stop block 62 to move more effectively under the pressure difference between the two ends.

[0058] Specifically, in this embodiment, a control pipe 61 is provided on the upper surface of the upper mounting plate 10. One end of the control pipe 61 forms the water inlet 6101, while the other end is closed and has the vent 63. The inner cavity of the control pipe 61 constitutes the control cavity 610. Furthermore, the water inlet 6101 is connected to the water outlet of the water pump 7 via an inlet pipe 91, and the water outlet 6102 is connected to the water inlet of the condenser pipe 21 via an outlet pipe 92. Figure 2 As shown.

[0059] Furthermore, the control mechanism 6 also includes a push rod 64. One end of the push rod 64 passes through the control chamber 610 along its length and is linked to the stop block 62, while the other end is located outside the control chamber 610 and is linked to the first clutch 51. When the water pump 7 is operating, the stop block 62 moves, driving the push rod 64, causing the first clutch 51 to engage with the second clutch 52. Figure 8 and Figure 9As shown. This allows the water pump 7 to start the steam guide fan 3 more effectively, thereby enabling the steam guide fan 3 to work better with the condenser zone 2. Preferably, one end of the push rod 64 is fixed to the stop block 62 and fitted with a return spring 65, while a spring seat 66 is also provided in the control chamber 610, with the return spring 65 sandwiched between the spring seat 66 and the stop block 62. When the inlet 6101 and outlet 6102 are connected, the return spring 65 is compressed, causing the stop block 62 to move towards the inlet 6101, thus disconnecting the inlet 6101 from the outlet 6102. When the water pump 7 stops working, the stop block 62 can quickly reset under the elastic force of the return spring 65, thus separating the water inlet 6101 and the air outlet. The condenser pipe 21 stops receiving water, and the condensation zone 2 stops working. At the same time, the push rod 64 resets under the action of the stop block 62, so the first clutch 51 and the second clutch 52 separate, the steam guide fan 3 and the centrifugal fan 4 are not linked, and the steam guide fan 3 does not rotate.

[0060] In this embodiment, a first transmission shaft 53 is further included, which is linked to the fan shaft 31 of the aforementioned steam-guiding fan 3. One end of the first transmission shaft 53 is connected to the other end of the aforementioned push rod 64, while the other end of the first transmission shaft 53 is fixed to the aforementioned first clutch 51. The first transmission shaft 53 is arranged along the moving direction of the first clutch 51 and can move back and forth along this direction under the drive of the aforementioned push rod 64, thereby engaging or disengaging the first clutch 51 and the second clutch 52. Thus, the first transmission shaft 53 can, on the one hand, realize the linkage between the steam-guiding fan 3 and the centrifugal fan 4, and on the other hand, can move under the drive of the push rod 64 to engage or disengage the first clutch 51 and the second clutch 52, thereby realizing the start-stop control of the steam-guiding fan 3. Preferably, a first transmission gear 55 is installed on the fan shaft 31 of the aforementioned steam-guiding fan 3, and a guide ridge 531 extending along its length is protruding from the outer surface of one end of the aforementioned first transmission shaft 53. It also includes a second transmission gear 56 that meshes with the first transmission gear 55. This second transmission gear 56 is sleeved on the first transmission shaft 53 and is fitted with the guide protrusion 531 through a guide groove 561 located at the edge of its central hole, with both providing a guiding fit. Figure 5 and Figure 6 As shown. On the one hand, it realizes the linkage between the first drive shaft 53 and the fan shaft 31, and on the other hand, it enables the first drive shaft 53 to move smoothly, thereby ensuring the reliability of the clutch control between the first clutch 51 and the second clutch 52.

[0061] Specifically, in this embodiment, the first clutch 51 is a wheel centered on the first drive shaft 53, and the second clutch 52 is linked to the motor shaft 40 of the centrifugal fan 4 via a second drive shaft 54 ​​extending along the length of the first drive shaft 53, and the second clutch 52 is a wheel centered on the second drive shaft 54. Further, the first clutch 51 and the second clutch 52 are positioned opposite each other, and on their opposing wheel end faces, one (specifically the second clutch 52 in this embodiment) has a protruding guide shaft 521 extending along the length of the first drive shaft 53, while the other (specifically the first clutch 51 in this embodiment) has a concentrically recessed arc-shaped guide groove 511. The guide shaft 511 can be inserted into the guide groove 511 and move along the guide groove 511, and abuts against the end of the guide groove 511 to link the first clutch 51 and the second clutch 52. In this state, with the first clutch 51 and the second clutch 52 engaged, the transmission mechanism 5 can smoothly transmit the kinetic energy output from the motor shaft 40 to the fan shaft 31, and the first transmission shaft 53 can smoothly disengage the first clutch 51 and the second clutch 52 when it moves. Furthermore, to achieve linkage between the second transmission shaft 54 ​​and the motor shaft 40, the second clutch 52 is fixed to one end of the second transmission shaft 54, while a third transmission gear 57 is fixed to the other end of the second transmission shaft 54. A fourth transmission gear 58, meshing with the third transmission gear 57, is mounted on the motor shaft 40 of the centrifugal fan 4. In this embodiment, the first transmission gear 55, the second transmission gear 56, the third transmission gear 57, and the fourth transmission gear 58 are all bevel gears.

[0062] 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.
