Description

Technical Field

[0001] The utility model relates to the field of cooking equipment, in particular to a steaming and baking cooking equipment. Background Art

[0002] The steam-bake cooking equipment has both steaming and baking functions. When the steaming function is in progress, the excess steam in the inner pot is discharged through the exhaust channel driven by the exhaust fan. For example, the Chinese utility model patent with patent number ZL 202220738174.8 (authorization announcement number CN217429750U) discloses a steam-bake exhaust structure and a steam-bake all-in-one machine; the Chinese utility model patent with patent number ZL202220149198.X (authorization announcement number CN216984569U) discloses a steam-bake all-in-one machine. The existing exhaust method will cause a large amount of condensed water to remain at the exhaust port, affecting the user experience. At the same time, the steam-bake cooking equipment is generally installed in an embedded manner, and the discharged steam will form condensed water on the cabinet, causing the cabinet to be damp, affecting the service life of the cabinet.

[0003] Furthermore, if the above problem is solved by controlling the steam discharge volume (for example, by setting a control valve to control the steam discharge flow), the steam accumulation in the inner tank will cause the inner tank internal pressure to be too high. In addition, the left and right sides of the lower end of the door body are rotatably connected to the box body through hinges, and in the closed state, the inner surface of the door body forms a circumferential seal with the edge of the inner tank through the door seal. Therefore, the tension on the upper end of the door body is relatively small. When the inner tank internal pressure is too high, the upper end of the door body is easily pushed open, causing the steam in the inner tank to leak outward through the gap at the upper end of the door body. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a steaming and baking cooking device with less external steam exhaust and high safety in use in view of the prior art.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a steaming and baking cooking device, comprising an inner pot and an exhaust channel arranged on the inner pot and used for exhausting the gas in the inner pot, characterized in that it also includes:

[0006] A control member, movably disposed in the exhaust passage and used to control the opening and closing of the exhaust port of the exhaust passage;

[0007] A steam outlet hole is provided on the side wall of the exhaust passage;

[0008] A condensing device is arranged outside the inner container and has an air inlet and a liquid outlet, wherein the air inlet is in fluid communication with the steam outlet;

[0009] A water collecting chamber having a liquid collecting hole, the liquid collecting hole being in fluid communication with the liquid outlet hole;

[0010] Furthermore, in the steaming mode, the actual opening area of ​​the exhaust port is proportional to the amount of steam entering the exhaust passage, while the steam flow rate of the steam outlet is inversely proportional to the actual opening area of ​​the exhaust port.

[0011] Furthermore, the control member is a plate member that is rotated up and down along the left and right directions of the exhaust passage, and when the control member is in a horizontal state, the actual opening area of ​​the exhaust port is the largest, and when the control member is arranged at the exhaust port end of the exhaust passage, the exhaust port is closed. In this way, the actual opening area of ​​the exhaust port can be adjusted by rotating the control member, thereby realizing the opening and closing control of the exhaust port.

[0012] Furthermore, the lower end of the control member is rotatably connected to the side wall of the exhaust passage through a rotating shaft extending left and right.

[0013] Furthermore, when the actual opening area of ​​the exhaust port is at its maximum, the control member fits against the inner bottom surface of the exhaust passage, and when the exhaust port is closed, the control member tilts backward from top to bottom along its own length direction. In this way, in the baking mode of the steam-bake cooking device or in the initial state of the steaming mode, it can ensure that the gas entering the exhaust passage is smoothly discharged through the exhaust port, and when the steam volume is at its maximum, the exhaust port can be closed to allow all the steam to enter the condensing device, and the control member can be tilted to buffer the collision between the steam flow and the control member, thereby reducing the condensation of steam at the control member, and further reducing the condensed water formed in the exhaust passage.

[0014] Furthermore, the steam outlet is arranged behind the control member and adjacent to the control member, so that the steam flow is blocked by the control member and can quickly enter the condensing device through the steam outlet after being turned.

[0015] Furthermore, the condensing device is arranged along the height direction of the inner pot, and comprises a condensing channel extending in a wave-like curvature, one end of the condensing channel is the air inlet hole and the other end is the liquid outlet hole, and the air inlet hole is located at the top of the condensing device and the liquid outlet hole is located at the bottom of the condensing device, and both are located on both sides of the condensing device. In this way, the steam entering through the air inlet hole can be fully condensed in the condensing channel.

[0016] Furthermore, the condensing device also includes a plate-shaped condensing block, which extends along the outer side of the inner tank on the side where the condensing block is located, and the condensing block is hollow inside so that its inner cavity forms the above-mentioned condensing channel, thereby facilitating the formation of the condensing channel structure and making the internal structure of the condensing device simple.

[0017] Furthermore, the condensation block is made of heat-conducting material, and a heat-insulating block is sandwiched between the condensation block and the outer side of the corresponding inner pot, thereby preventing the residual heat other than the radiation of the inner pot from affecting the condensation effect of the condensation device, and ensuring the condensation effect of the condensation device on the steam.

[0018] Furthermore, a heating plate is arranged on the inner bottom surface of the inner pot, and the water collecting chamber is arranged under the bottom plate of the inner pot, so that the residual heat generated by the heating plate can be used to heat the condensed water collected in the water collecting chamber, thereby realizing self-cleaning of the condensed water.

[0019] Furthermore, a horizontally extending water collecting plate is detachably provided on the outer bottom surface of the inner container, and the water collecting plate is hollow inside so that its inner cavity forms the water collecting cavity, and the water collecting cavity has a liquid outlet. In this way, when cleaning the water in the water collecting cavity, the water collecting plate can be removed and the water in the water collecting cavity can be poured out.

[0020] Furthermore, the exhaust port of the exhaust channel is provided with guide blocks extending forward and backward, and the guide blocks are at least two and are arranged at intervals in the left and right directions, so that the airflow at the exhaust port can be guided so that the airflow is discharged smoothly from the exhaust port, and the condensed water formed at the exhaust port can be further reduced in the steam mode.

[0021] Further, the guide block includes a first guide block and a second guide block, wherein the first guide blocks are at least three and are respectively arranged at the left end, the right end and the center of the exhaust port along the length direction, and at least one second guide block is arranged between two adjacent first guide blocks.

[0022] Among them, each first guide block is a left-right symmetrical structure, and the left and right sides of each first guide block are close to the center from back to front, and the rear end surface of each first guide block extends vertically in the left and right directions, and the shape of each second guide block is a plate body extending front and back. In this way, the steam flow is divided through each first guide block, and the divided steam volume diffuses and flows from back to front under the guidance of the side of each first guide block and each second guide block, further improving the stability of steam flow.

[0023] Furthermore, a detection device for detecting steam concentration is installed in the exhaust passage, the detection device is electrically connected to the controller of the steam-bake cooking device, and a driving device for driving the above-mentioned control element to open and close the exhaust port is electrically connected to the above-mentioned controller. The amount of steam entering the exhaust passage can be detected by the detection device, and the detection information is fed back to the controller, which controls the driving device to realize the rotation of the control element, thereby realizing the adjustment of the actual opening area of ​​the exhaust port.

[0024] Furthermore, there are two detection devices, one of which is arranged at the air inlet end of the exhaust passage, and the other is arranged at the exhaust outlet end of the exhaust passage and is located behind the above-mentioned control element, so that the steam amount at the control element can be detected more accurately.

[0025] Compared with the prior art, the utility model has the advantages that: a control member is provided in the exhaust channel of the utility model, and the control member is used to control the opening and closing of the exhaust port of the exhaust channel, and a steam outlet hole is also provided on the exhaust channel. In addition, a condensing device and a water collecting chamber are also provided. Moreover, in the steaming mode, the actual opening area of ​​the exhaust port is inversely proportional to the amount of steam entering the exhaust channel, and the steam flow rate of the steam outlet is inversely proportional to the actual opening area of ​​the exhaust port. In this way, in the initial state of the steaming mode, the amount of steam entering the exhaust channel is small, and the actual opening area of ​​the exhaust port is the largest. As the amount of steam entering the exhaust channel increases, the actual opening area of ​​the exhaust port decreases, and the control member prevents the steam from being discharged through the exhaust port, reducing the amount of steam discharged from the exhaust port, so that part of the steam enters the condensing device through the steam outlet hole, and the steam condenses in the condensing device, and the formed condensed water is collected in the water collecting chamber. Until the steam amount is the largest, the control member closes the exhaust port, and all the steam entering the exhaust channel enters the condensing device through the steam outlet hole.

[0026] It can be seen that the utility model can reduce the steam exhaust volume and avoid the formation of excessive condensed water at the exhaust port, while preventing steam from accumulating inside the inner pot and causing excessive internal pressure in the inner pot, thereby ensuring the safety of the steaming and baking cooking equipment.

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0031] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0032] like Figures 1 to 3 As shown, a steaming and baking cooking device comprises a box body 1 with an opening on the front side and an inner pot 2 which is arranged in the box body 1 and has an opening on the front side. The inner pot 2 is provided with an exhaust passage 3, and the exhaust passage 3 is used for exhausting the gas in the inner pot 2. In this embodiment, the exhaust passage 3 extends forward and backward, and its rear end has an air inlet 31 which is fluidically connected to the exhaust port 32 of the inner pot 2, and the front end is an exhaust port 32 connected to the outside. In addition, the rear end of the exhaust passage 3 is an air inlet and is provided with an exhaust fan (not shown), so that the exhaust fan is used to drive the gas entering the exhaust passage 3 to be discharged through the exhaust port 32.

[0033] Furthermore, the steam-bake cooking device further includes a control member 4, a steam outlet 34, a condensing device 5 and a water collecting chamber (not shown). The control member 4 is movably arranged in the exhaust channel 3 and is used to control the opening and closing of the exhaust port 32 of the exhaust channel 3. The steam outlet 34 is provided on the side wall of the exhaust channel 3. The condensing device 5 is arranged outside the inner pot 2 and has an air inlet 501 and a liquid outlet 502, respectively, wherein the air inlet 501 is fluidly connected with the steam outlet 34. The water collecting chamber has a liquid collecting hole 601, which is fluidly connected with the liquid outlet 502. Moreover, in the steaming mode, the actual opening area of ​​the exhaust port 32 is proportional to the amount of steam entering the exhaust channel 3, while the steam flow rate of the steam outlet 34 is inversely proportional to the actual opening area of ​​the exhaust port 32. In this embodiment, the steam outlet hole 34 is connected to the air inlet hole 501 through a steam outlet pipe 341 , and the liquid outlet hole 502 is connected to the liquid collecting hole 601 through a liquid outlet pipe 5021 .

[0034] As can be seen from the above, the exhaust channel 3 of the utility model is provided with a control member 4, which is used to control the opening and closing of the exhaust port 32 of the exhaust channel 3. At the same time, a steam outlet 34 is also provided on the exhaust channel 3. In addition, a condensing device 5 and a water collecting chamber are also provided. Moreover, in the steaming mode, the actual opening area of ​​the exhaust port 32 is inversely proportional to the amount of steam entering the exhaust channel 3, and the steam flow rate of the steam outlet 34 is inversely proportional to the actual opening area of ​​the exhaust port 32. In this way, in the initial state of the steaming mode, the amount of steam entering the exhaust channel 3 is small, and the actual opening area of ​​the exhaust port 32 is the largest. As the amount of steam entering the exhaust channel 3 increases, the actual opening area of ​​the exhaust port 32 decreases, and the control member 4 prevents the steam from being discharged through the exhaust port 32, reducing the amount of steam discharged from the exhaust port 32, so that part of the steam enters the condensing device 5 through the steam outlet 34, and the steam condenses in the condensing device 5, and the formed condensed water is collected in the water collecting chamber. When the steam volume reaches the maximum, the control unit 4 closes the exhaust port 32, and all the steam entering the exhaust channel 3 enters the condensing device 5 through the steam outlet 34. It can be seen that the utility model can reduce the steam discharge volume and avoid excessive condensed water from forming at the exhaust port 32, while preventing the steam from accumulating inside the inner pot 2 and causing excessive internal pressure of the inner pot 2, thereby ensuring the safety of the steam-bake cooking device.

[0035] Furthermore, in this embodiment, the control member 4 is a plate member that is rotated up and down along the left and right directions of the exhaust passage 3, and when the control member 4 is in a horizontal state, the actual opening area of ​​the exhaust port 32 is the largest, and when the control member 4 is arranged at the end of the exhaust port 32 of the exhaust passage 3, the exhaust port 32 is closed. In this way, the actual opening area of ​​the exhaust port 32 can be adjusted by rotating the control member 4, thereby realizing the opening and closing control of the exhaust port 32. Further, specifically, the lower end of the control member 4 is rotatably connected to the side wall of the exhaust passage 3 through a rotating shaft extending left and right. Moreover, when the actual opening area of ​​the exhaust port 32 is the largest, the control member 4 fits the inner bottom surface of the exhaust passage 3 in the horizontal direction, and when the exhaust port 32 is closed, the control member 4 tilts backward from top to bottom along its own length direction. In this way, in the baking mode of the steam-bake cooking device or in the initial state of the steaming mode, the gas entering the exhaust channel 3 can be smoothly discharged through the exhaust port 32. When the steam volume is maximum, the exhaust port 32 can be closed to allow all the steam to enter the condensing device 5, and the collision between the steam flow and the control member 4 can be buffered by tilting the control member 4, thereby reducing the condensation of steam at the control member 4, and further reducing the condensed water formed in the exhaust channel 3.

[0036] Preferably, the steam outlet 34 is provided behind the control member 4 and adjacent to the control member 4. In this way, the steam flow is blocked by the control member 4 and can quickly enter the condensing device 5 through the steam outlet 34 after being turned.

[0037] Furthermore, the condensation device 5 is arranged along the height direction of the inner tank 2, and includes a condensation channel 50 extending in a wave-like curvature, one end of the condensation channel 50 is the air inlet 501 and the other end is the liquid outlet 502. In addition, the air inlet 501 is located at the top of the condensation device 5 and the liquid outlet 502 is located at the bottom of the condensation device 5, and both are located on both sides of the condensation device 5, so that the steam entering through the air inlet 501 can be fully condensed in the condensation channel 50. Specifically, in this embodiment, the condensation device 5 also includes a plate-shaped condensation block 51, which extends along the outer side surface direction of the inner tank 2 on its side, and the condensation block 51 is hollow inside so that its inner cavity forms the condensation channel 50. This facilitates the formation of the condensation channel 50 structure and can make the internal structure of the condensation device 5 simple. Preferably, the above-mentioned condensation block 51 is made of heat-conducting material, and an insulation block (not shown) is sandwiched between the condensation block 51 and the corresponding outer side surface of the inner tank 2, so as to avoid the residual heat other than the radiation of the inner tank 2 from affecting the condensation effect of the condensation device 5, thereby ensuring the condensation effect of the condensation device 5 on the steam.

[0038] In this embodiment, there are two steam outlet holes 34, one of which is opened on the left wall of the exhaust channel 3, and the other is opened on the right wall of the exhaust channel 3. Correspondingly, there are also two condensing devices 5 and they correspond one-to-one to the steam outlet holes 34, and one of the condensing devices 5 is arranged on the left side of the inner tank 2, and the other condensing device 5 is arranged on the right side of the inner tank 2.

[0039] Furthermore, a heating plate (not shown) is provided on the inner bottom surface of the inner pot 2, and the water collecting chamber is provided under the bottom plate of the inner pot 2. In this way, the residual heat generated by the heating plate can be used to heat the condensed water collected in the water collecting chamber, thereby realizing self-cleaning of the condensed water. Still further, a horizontally extending water collecting plate 6 is detachably provided on the outer bottom surface of the inner pot 2, and the inner part of the water collecting plate 6 is hollow so that its inner cavity forms the above-mentioned water collecting chamber, and the water collecting chamber has a liquid outlet 602. When cleaning the water in the water collecting chamber, the water collecting plate 6 is disassembled and the water in the water collecting chamber is poured out. It can be seen that in this embodiment, there are two ways to treat the water collected in the water collecting chamber: the first is to realize self-cleaning by utilizing the residual heat generated by the heating plate; the second is to manually disassemble the water collecting plate 6 and pour out the water in the water collecting chamber.

[0040] Further, the exhaust port 32 of the exhaust channel 3 is provided with guide blocks 33 extending forward and backward at intervals, and the guide blocks 33 are at least two and are arranged at intervals in the left and right directions. Thus, the airflow at the exhaust port 32 can be guided so that the airflow is discharged smoothly from the exhaust port 32, and the condensed water formed at the exhaust port 32 can be further reduced in the steam mode. Specifically, the guide blocks 33 include a first guide block 331 and a second guide block 332, wherein the first guide blocks 331 are three and are respectively arranged at the left end, the right end and the center of the exhaust port 32 along the length direction, and three second guide blocks 332 are arranged at intervals between two adjacent first guide blocks 331. Among them, each first guide block 331 is a left-right symmetrical structure, and the left and right sides of each first guide block 331 are respectively close to the center from back to front, and the rear end face of each first guide block 331 is respectively extended vertically in the left and right directions, and the shape of each second guide block 332 is respectively in the shape of a plate extending forward and backward. In this way, the steam flow is split through each first guide block 331, and the split steam volume diffuses and flows from back to front under the guidance of the side of each first guide block 331 and each second guide block 332, further improving the stability of the steam flow.

[0041] Furthermore, a detection device 7 for detecting steam concentration is installed in the exhaust passage 3, and the detection device 7 is electrically connected to the controller of the steam-bake cooking device, and the driving device for driving the control member 4 to open and close the exhaust port 32 is electrically connected to the controller. The detection device 7 can detect the amount of steam entering the exhaust passage 3, and the detection information is fed back to the controller, which controls the driving device to realize the rotation of the control member 4, thereby realizing the adjustment of the actual opening area size of the exhaust port 32. Preferably, there are two detection devices 7, one of which is arranged at the air inlet end of the exhaust passage 3, and the other is arranged at the exhaust port 32 end of the exhaust passage 3 and is located behind the control member 4. Thereby, the amount of steam at the control member 4 can be detected more accurately. In this embodiment, each detection device 7 is a water vapor infrared sensor.

[0042] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two components or parts (hereinafter collectively referred to as the first part and the second part respectively), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected to each other, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
