Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a cooking utensil. Background Art

[0002] With the development of microwave oven technology, new functions have been added to cooking appliances. For example, in related art, the steam-cooking function of the steam outlet is integrated with the healthy and delicious oxygen-variable oven and steaming functions. However, this leads to a complex structure of the cooking appliance, which also reduces the efficiency of the cooking appliance assembly and increases the cost. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] To this end, the present invention provides a cooking utensil.

[0005] The present invention provides a cooking appliance, comprising: a main body, the main body including a cooking cavity; a steam generating assembly, connected to the cooking cavity and used to provide steam for the cooking cavity; a ventilation assembly, the ventilation assembly including a first ventilation pipe and a ventilation box, the ventilation box being connected to the cooking cavity through the first ventilation pipe, and the ventilation box being connected to the external environment; an exhaust assembly, the exhaust assembly including an exhaust pipe and a condensation drainer, the exhaust pipe being connected to the cooking cavity and the condensation drainer, and the condensation drainer being further connected to the ventilation box.

[0006] The cooking appliance proposed in the present invention includes a main body, a steam generating assembly, a ventilation assembly, and an exhaust assembly. The main body includes a cooking cavity, which can be used to place food to be cooked. The steam generating assembly is connected to the cooking cavity and, when in operation, can provide steam into the cooking cavity, thereby cooking the food to be cooked in the cooking cavity. The ventilation assembly includes a first ventilation pipe and a ventilation box that are connected to each other. The ventilation box is connected to the cooking cavity via the first ventilation pipe and is also connected to the external environment. When the ventilation assembly is in operation, it can introduce air from the external environment into the cooking cavity, thereby achieving a ventilation function. The exhaust assembly includes an exhaust pipe and a condensation drain that are connected to each other. The exhaust pipe is connected to the cooking cavity and the condensation drain, and the condensation drain is also connected to the ventilation box. When the ventilation assembly is in operation, it can discharge steam from the cooking cavity to the external environment, thereby achieving an exhaust function.

[0007] In particular, the cooking appliance of the present invention utilizes an exhaust assembly whose condensate drainer communicates with the ventilation box, achieving an integrated exhaust and ventilation system. This makes the cooking appliance compact and facilitates modular assembly of the entire appliance. Specifically, when steam within the cooking cavity needs to be exhausted, the exhaust assembly operates. At this point, the steam within the cooking cavity enters the condensate drainer through the exhaust pipe, where at least a portion of the steam condenses into condensate water. A smaller portion of the steam and air enters the ventilation box and is discharged to the outside environment through the ventilation box.

[0008] In this way, the condensation drainer and ventilation box work together to achieve mist-free exhaust from the cooking appliance. This prevents high-temperature steam from harming the user while also preventing the steam from affecting other electrical devices around the cooking appliance, making the cooking appliance safer to use. Furthermore, the condensation drainer guides air into the ventilation box, where it is then discharged to the outside environment. This integrates the ventilation and exhaust functions of the cooking appliance into the ventilation box, using the ventilation box as a carrier to achieve the integrated configuration of different functions. This facilitates the modular design of the cooking appliance, simplifies its structural complexity, and facilitates its production and assembly, thereby reducing the cost of the cooking appliance.

[0009] Furthermore, the cooking appliance proposed in the present invention can achieve different cooking modes through the coordination of a steam generating component, a ventilation component, and an exhaust component. Specifically, as the steam generating component discharges steam into the cooking chamber, as the amount of steam increases, the air originally in the cooking chamber is discharged through the exhaust component, reducing the oxygen content in the cooking chamber. In this case, the cooking appliance proposed in the present invention can perform low-oxygen cooking, thereby reducing the production of harmful substances in food. In addition, during the operation of the ventilation component, oxygen from the external environment can be reintroduced into the cooking chamber, allowing the food in the cooking chamber to fully undergo the Maillard reaction, thereby improving the cooking effect of the food.

[0010] In this way, the cooking appliance proposed by the present invention integrates the ventilation function and the exhaust function on the ventilation box, and can change the oxygen content in the cooking cavity to achieve oxygen-variable cooking and oxygen-free cooking, so as to enhance the cooking function of the cooking appliance and improve the cooking effect of food.

[0011] In some possible designs, the cooking appliance further includes: a steam flow channel located in the ventilation box, the condensation drainer being connected to the steam flow channel; and a ventilation channel located in the ventilation box, the ventilation pipe being connected to the ventilation channel.

[0012] In this design, the cooking appliance also includes a steam flow channel and a ventilation channel, both of which are located within the ventilation box. The condensate drain is connected to the steam flow channel. Thus, during operation of the cooking appliance, steam within the cooking chamber can enter the steam flow channel via the exhaust assembly and be discharged to the outside environment through the steam flow channel. Furthermore, the ventilation assembly is connected to the ventilation channel. Thus, during operation of the cooking appliance, air from the outside environment can enter the ventilation channel and enter the cooking chamber through the ventilation assembly.

[0013] In some possible designs, the steam flow channel, the ventilation channel and the ventilation box are an integrated structure.

[0014] In this design, the steam flow channel, ventilation channel, and ventilation box form an integrated structure. In other words, the present invention integrates the steam flow channel and ventilation channel into the ventilation box, using the ventilation box as a carrier to achieve the integrated ventilation and exhaust functions. This integrated design significantly simplifies the structure of the cooking appliance, facilitating its processing and assembly, as well as facilitating the arrangement of the remaining components.

[0015] In some possible designs, the ventilation component also includes: a second ventilation pipe, located in the ventilation box and connected to the first ventilation pipe and the external environment; a driving structure for adjusting the opening area of the second ventilation pipe; wherein the second ventilation pipe and the first ventilation pipe are an integrated structure, or the second ventilation pipe is connected to the first ventilation pipe.

[0016] In this design, the ventilation assembly also includes a second ventilation tube and a drive mechanism. The second ventilation tube is located inside the ventilation box and connects to the first ventilation tube and the external environment. The drive mechanism is located inside the ventilation box and can be used to adjust the opening area of the second ventilation tube. The second ventilation tube and the first ventilation tube are integrally formed or connected to each other.

[0017] Specifically, when outside air needs to be introduced, the driving mechanism opens the second ventilation duct, allowing air from the outside environment to enter the cooking cavity through the second ventilation duct. During the process of cooking food in the cooking cavity using steam, the driving mechanism closes the second ventilation duct, thereby preventing steam leakage from the cooking cavity.

[0018] Furthermore, the opening area of the second ventilation duct can be controlled based on actual conditions. For example, when the cooking cavity is large or a large amount of food is being cooked, rapid entry of external air into the cooking cavity is required, and the second ventilation duct can be fully opened. When the cooking cavity is small or a small amount of food is being cooked, rapid entry of external air into the cooking cavity is not required, and the second ventilation duct can be partially opened.

[0019] In this design, the second ventilation pipe and the first ventilation pipe can be an integrated structure. That is, the present invention directly extends a portion of the first ventilation pipe into the ventilation box to serve as the second ventilation pipe, and at least a portion of the second ventilation pipe is installed in the ventilation channel.

[0020] In this design, the second ventilation pipe and the first ventilation pipe can be separated and connected to each other. In this case, the steam in the first heat exchange pipe first enters the steam channel, then flows through the steam channel into the second ventilation pipe and is discharged through the second ventilation pipe.

[0021] In some possible designs, the second ventilation tube is a hose, and the driving structure can deform the second ventilation tube to adjust the opening area of the second ventilation tube.

[0022] In this design, the second ventilation tube is a flexible hose. The hose is capable of deforming under external force. Specifically, when the hose is squeezed by the drive mechanism, the deformation closes the internal flow channel, blocking the flow of gas. When the drive mechanism releases the hose, it returns to its original shape, unaffected by the external force, and the internal flow channel fully or partially opens, allowing gas to pass through.

[0023] In some possible designs, the driving structure includes: a first driving member; a movable member connected to the first driving member and in contact with the second ventilation tube, and the movable member can adjust the opening area of the second ventilation tube under the drive of the first driving member.

[0024] In this design, the drive structure includes a first drive member and a movable member. The movable member is connected to the first drive member and contacts the second ventilation tube. Thus, during operation of the drive structure, the first drive member drives the movable member, which in turn controls the opening area of the second ventilation tube.

[0025] Specifically, the first driving member can be a motor and the movable member can be a cam. In this way, the motor can drive the cam to rotate, thereby causing the cam to press the second heat exchange tube, thereby causing the second ventilation tube to deform to adjust the opening area.

[0026] In some possible designs, the cooking appliance further includes: a detection device, disposed on the ventilation box, for detecting the state of food in the cooking cavity.

[0027] In this design, the cooking appliance also includes a detection device. This detection device is integrated into the ventilation box and uses it to detect the state of food within the cooking chamber. Thus, the cooking appliance proposed by this invention integrates detection, ventilation, and exhaust functions within the ventilation box, making the cooking appliance compact and facilitating modular assembly.

[0028] Specifically, the detection device may adopt a temperature sensor (for example, an infrared sensor), and detect the temperature of the food in the cooking cavity through the temperature sensor.

[0029] In some possible designs, the cooking appliance further includes: a mounting structure located inside the ventilation box, and a detection device is arranged on the mounting structure; wherein, the mounting structure is located on the side of the ventilation box facing the cooking cavity, and the steam flow channel is located between the ventilation channel and the mounting structure.

[0030] In this design, the cooking appliance also includes a mounting structure, which is located within the ventilation box. The detection device is mounted on the mounting structure to ensure its integration within the ventilation box, achieving a modular design for the cooking appliance. Furthermore, the mounting structure is located on the side of the ventilation box facing the cooking cavity, ensuring that the detection device is mounted facing the cooking cavity, enabling the detection device to accurately detect the temperature of food within the cooking cavity. Furthermore, the steam flow path is located between the ventilation channel and the mounting structure, ensuring that the mounting structure, steam flow path, and ventilation channel are positioned appropriately on the ventilation box to ensure that steam and external air do not affect the detection device's results.

[0031] In some possible designs, the mounting structure and the ventilation box are integrated into one structure.

[0032] In this design, the mounting structure and the ventilation box form an integrated structure. That is, the present invention integrates the mounting structure with the ventilation box, and the detection device is mounted via the mounting structure. This allows the present invention to integrate ventilation, exhaust, and detection functions using the ventilation box as a carrier, making the cooking appliance compact and facilitating modular assembly of the entire unit.

[0033] In some possible designs, the cooking appliance further includes a heat dissipation duct located in the ventilation box, and the detection device and at least a portion of the ventilation component are located in the heat dissipation duct; the cooking appliance further includes a heat dissipation device for supplying air to the heat dissipation duct.

[0034] In this design, the cooking appliance also includes a heat dissipation duct, which is located within the ventilation box. The detection device and at least a portion of the ventilation assembly are located within the heat dissipation duct (specifically, the drive structure of the ventilation assembly is located within the heat dissipation duct). Furthermore, the cooking appliance also includes a heat dissipation device, which is disposed within the heat dissipation duct and can supply air to the heat dissipation duct during operation to dissipate heat from components within the heat dissipation duct.

[0035] Furthermore, the driving structures of the detection device and the ventilation component are both arranged inside the heat dissipation duct, so that the present invention can simultaneously dissipate heat for the driving structures of the detection device and the ventilation component through a heat dissipation device, effectively simplifying the heat dissipation-related structures of the cooking appliance, and also helping to reduce the cost and assembly difficulty of the cooking appliance.

[0036] Specifically, during operation of the cooking appliance, the temperature of the detection device and the drive structure of the ventilation assembly will rise. At this point, the heat dissipation device operates, drawing cool air from the outside environment into the heat dissipation duct. This cool air then flows through the detection device and the drive structure of the ventilation assembly, effectively controlling their temperatures and cooling them.

[0037] In some possible designs, the heat dissipation duct and the ventilation box are an integrated structure.

[0038] In this design, the heat dissipation duct and the ventilation box form an integrated structure. In other words, the present invention integrates the heat dissipation duct with the ventilation box. This allows the present invention to integrate the heat dissipation function within the ventilation box, facilitating a modular design for heat dissipation and ventilation, thereby simplifying the structure of the cooking appliance.

[0039] In some possible designs, the ventilation box further includes: a box body, in which the heat dissipation duct, the steam flow duct and the ventilation channel are located; and a cover body, which is arranged on the box body and is provided with a ventilation grille.

[0040] In this design, the ventilation box includes a box body and a lid. The heat dissipation duct, steam flow channel, and ventilation channel are located in the box body, and the lid is mounted on the box body. In addition, the lid is equipped with a ventilation grille to ensure communication between the cooking chamber and the external environment.

[0041] In some possible designs, the cover is detachably connected to the box body.

[0042] In this design, the cover is detachably connected to the box body. In this way, during use, the user can remove the cover to inspect the components inside the ventilation box and to clean the inside of the ventilation box to ensure the cleanliness of the interior of the ventilation box and the entire cooking utensil.

[0043] In some possible designs, the cooking appliance further includes: an air inlet, which is arranged on the main body, and the steam generating component is connected to the cooking cavity through the air inlet; an exhaust port, which is arranged on the main body, and the exhaust pipe is connected to the cooking cavity through the exhaust port; wherein the exhaust port is arranged lower than the air inlet.

[0044] In this design, the cooking appliance also includes an air inlet and an exhaust port. The air inlet is located on the main body, and the steam generating assembly is connected to the cooking cavity through the air inlet, allowing steam generated by the steam generating assembly to enter the cooking cavity from the top. Furthermore, an exhaust port is located on the main body, and an exhaust pipe is connected to the cooking cavity through the exhaust port. The exhaust port is positioned lower than the air inlet to ensure that air in the cooking cavity can be discharged from the bottom of the cooking cavity.

[0045] Specifically, during operation, the steam generating assembly can input steam into the cooking chamber through the air inlet, with the steam entering at a higher position than the exhaust port. Specifically, the density of the steam is greater than the density of the gas within the cooking chamber, resulting in the formation of a steam layer upon entry. As the steam volume increases, the steam layer continuously descends. This descending steam layer forces the air within the cooking chamber to be expelled through the exhaust port, thereby reducing the oxygen content within the cooking chamber. This low-oxygen cooking process, utilizing the steam-injection, low-Reynolds oxygen removal technology, allows for a period of time, reducing the production of harmful substances in food.

[0046] In some possible designs, the cooking appliance further includes: a fan assembly, the fan assembly including a second driving member and a fan connected to each other, and the fan is located in the cooking cavity.

[0047] In this design, the cooking appliance also includes a fan assembly. The fan assembly includes a second drive member and a fan connected thereto, the second drive member being capable of driving the fan to rotate. Furthermore, the fan of the fan assembly is located within the cooking cavity and, when rotating, generates negative pressure within the cooking cavity, thereby allowing air from the external environment to enter the cooking cavity through the ventilation assembly.

[0048] In some possible designs, the main body further includes a back plate, and the ventilation assembly and the exhaust assembly are mounted on the back plate.

[0049] In this design, the main body also includes a back panel. The ventilation and exhaust components are integrated into the back panel. Thus, the cooking appliance proposed by the present invention achieves an integrated design of the ventilation and exhaust components, simplifying the overall structure of the cooking appliance, facilitating its manufacture and assembly, as well as subsequent maintenance.

[0050] Specifically, during the assembly of the cooking appliance, it is only necessary to install the back plate to the inner pot of the cooking appliance, and respectively connect the first ventilation duct and the second ventilation duct to the cooking cavity.

[0051] In some possible designs, the condensation drainer includes: a condensation chamber connected to the exhaust pipe and the ventilation box; and a flow guide component connected to the condensation chamber and the cooking chamber for guiding the flow to the cooking chamber.

[0052] In this design, the condensate drainer includes a condensation chamber and a flow guide. The condensation chamber is connected to an exhaust pipe and a ventilation box, allowing steam from the cooking chamber to enter the chamber through the exhaust pipe. Furthermore, the flow guide connects the condensation chamber and the cooking chamber, allowing condensed water to flow back into the cooking chamber through the flow guide, thereby collecting the condensed water and preventing it from coming into contact with the electrical control components of the cooking appliance.

[0053] In some possible designs, the cooking appliance includes a steamer or a microwave-steamer-oven combination.

[0054] In this design, cooking appliances include but are not limited to the following products: steamer, microwave oven and steam-bake combination machine.

[0055] Additional aspects and advantages of the invention will become apparent from the description which follows, or may be learned by practice of the invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0071] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0072] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0073] Refer to the following Figures 1 to 12 The cooking appliance 100 according to some embodiments of the present invention will be described. Figure 5 The middle dashed line indicates the direction of airflow; Figure 8 The dashed line indicates the direction of steam flow.

[0074] like Figure 1 As shown, the first embodiment of the present invention provides a cooking appliance 100 , comprising: a body 102 , a steam generating assembly (not shown in the figure), a ventilation assembly 106 and an exhaust assembly 112 .

[0075] Among them, Figure 1 and Figure 9 As shown, the body 102 includes a cooking cavity 104, which can be used to place food to be cooked. The steam generating assembly is connected to the cooking cavity 104 and can provide steam to the cooking cavity 104 during operation, thereby cooking the food to be cooked in the cooking cavity 104. Figure 1 、 Figure 2 and Figure 3 As shown, the ventilation component 106 includes a first ventilation pipe 108 and a ventilation box 110 that are connected to each other. The ventilation box 110 is connected to the cooking cavity 104 through the first ventilation pipe 108, and the ventilation box 110 is also connected to the external environment; when the ventilation component 106 is in operation, it can introduce air from the external environment into the cooking cavity 104, thereby realizing the ventilation function.

[0076] like Figure 1 、 Figure 2 and Figure 3 As shown, the exhaust component 112 includes an exhaust pipe 114 and a condensation drainer 116 that are connected to each other. The exhaust pipe 114 is connected to the cooking cavity 104 and the condensation drainer 116, and the condensation drainer 116 is also connected to the ventilation box 110. When the ventilation component 106 is operated, it can discharge the steam in the cooking cavity 104 to the external environment, thereby realizing the exhaust function.

[0077] In particular, in the cooking appliance 100 proposed by the present invention, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the condensation drainer 116 of the exhaust assembly 112 is connected to the ventilation box 110, thereby realizing the integrated setting of exhaust and ventilation, making the structure of the cooking appliance 100 compact and facilitating the modular assembly of the entire cooking appliance 100.

[0078] Specifically, when it is necessary to discharge the steam in the cooking cavity 104, the exhaust component 112 operates; at this time, the steam in the cooking cavity 104 enters the condensation drainer 116 through the exhaust pipe 114, at least a portion of the steam condenses into condensed water in the condensation drainer 116, and a small portion of steam and air enters the ventilation box 110 and is discharged into the external environment through the ventilation box 110.

[0079] In this way, through the cooperation of the condensation drainer 116 and the ventilation box 110, mist-free discharge of the cooking appliance 100 can be achieved. On the one hand, it avoids the discharge of high-temperature steam to harm the user, and on the other hand, it also avoids the steam affecting the use of other electrical equipment around the cooking appliance 100, making the use of the cooking appliance 100 safer.

[0080] Furthermore, the condensation drain 116 guides air into the ventilation box 110 and discharges the air into the external environment through the ventilation box 110, thereby integrating the ventilation and exhaust functions of the cooking appliance 100 into the ventilation box 110. The ventilation box 110 serves as a carrier for implementing the integrated configuration of different functions, which facilitates the modular design of the cooking appliance 100, simplifies the structural complexity of the cooking appliance 100, and facilitates the production and assembly of the cooking appliance 100, thereby reducing the cost of the cooking appliance 100.

[0081] Furthermore, the cooking appliance 100 proposed in the present invention can realize different cooking modes through the cooperation of the steam generating component, the ventilation component 106 and the exhaust component 112.

[0082] Specifically, as the steam generating assembly discharges steam into the cooking cavity 104, as the steam volume increases, the air already inside the cooking cavity 104 is exhausted through the exhaust assembly 112, reducing the oxygen content within the cooking cavity 104. This allows the cooking device 100 of the present invention to perform low-oxygen cooking, thereby reducing the production of harmful substances in food. Furthermore, while the ventilation assembly 106 is operating, it can also re-introduce oxygen from the external environment into the cooking cavity 104, allowing the food in the cooking cavity 104 to fully undergo the Maillard reaction, thereby improving the cooking effect.

[0083] In this way, the cooking utensil 100 proposed in the present invention, based on integrating the ventilation function and the exhaust function on the ventilation box 110, can change the oxygen content in the cooking cavity 104, realize oxygen-variable cooking and oxygen-free cooking, so as to enhance the cooking function of the cooking utensil 100 and improve the cooking effect of food.

[0084] The second embodiment of the present invention provides a cooking utensil 100, which further comprises:

[0085] like Figure 4 and Figure 8 As shown, the cooking appliance 100 further includes a steam flow channel 118 and a ventilation channel 120, both of which are located within the ventilation box 110. The condensation drain 116 is connected to the steam flow channel 118. Thus, during operation of the cooking appliance 100, steam within the cooking cavity 104 can enter the steam flow channel 118 via the exhaust assembly 112 and be discharged to the outside environment through the steam flow channel 118. Furthermore, the ventilation assembly 106 is connected to the ventilation channel 120. Thus, during operation of the cooking appliance 100, air from the outside environment can enter the ventilation channel 120 and enter the interior of the cooking cavity 104 via the ventilation assembly 106.

[0086] In this embodiment, the steam duct 118, ventilation channel 120, and ventilation box 110 further form an integrated structure. That is, the present invention integrates the steam duct 118 and ventilation channel 120 into the ventilation box 110, thereby integrating the ventilation and exhaust functions into the ventilation box 110 using the ventilation box 110 as a carrier. This integrated design of the steam duct 118, ventilation channel 120, and ventilation box 110 significantly simplifies the structure of the cooking appliance 100, facilitating its processing and assembly, as well as facilitating the arrangement of its remaining components.

[0087] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0088] The third embodiment of the present invention provides a cooking utensil 100, which further comprises:

[0089] like Figure 4 、 Figure 5 and Figure 7 As shown, the ventilation assembly 106 further includes a second ventilation tube 122 and a drive structure 124. The second ventilation tube 122 is disposed inside the ventilation box 110 and is connected to the first ventilation tube 108 and the external environment; the drive structure 124 is disposed inside the ventilation box 110 and is used to adjust the opening area of the second ventilation tube 122.

[0090] Specifically, when it is necessary to introduce external air, the driving structure 124 opens the second ventilation tube 122, and air from the external environment can enter the cooking cavity 104 through the second ventilation tube 122. When the food in the cooking cavity 104 is being cooked with steam, the driving structure 124 closes the second ventilation tube 122, thereby preventing steam leakage from the cooking cavity 104.

[0091] Furthermore, the opening area of the second ventilation duct 122 can be controlled according to actual conditions. For example, when the volume of the cooking cavity 104 is large or a large amount of food is being cooked, it is necessary to quickly allow outside air to enter the cooking cavity 104, and the second ventilation duct 122 can be controlled to be fully open. When the volume of the cooking cavity 104 is small or a small amount of food is being cooked, it is not necessary to quickly allow outside air to enter the cooking cavity 104, and the second ventilation duct 122 can be controlled to be partially open.

[0092] In this embodiment, the second ventilation tube 122 and the first ventilation tube 108 can be an integrated structure. That is, the present invention directly extends a portion of the first ventilation tube 108 into the ventilation box 110 to serve as the second ventilation tube 122. In this case, at least a portion of the second ventilation tube 122 is disposed in the ventilation passage 120.

[0093] In this embodiment, the second ventilation pipe 122 and the first ventilation pipe 108 can be a separate structure, and the first ventilation pipe 108 is connected to the second ventilation pipe 122. At this time, the steam in the first heat exchange pipe first enters the steam channel, then flows through the steam channel into the second ventilation pipe 122, and is discharged through the second ventilation pipe 122.

[0094] In this embodiment, further, Figure 4 、 Figure 5 and Figure 7 As shown, the second ventilation tube 122 is a flexible tube. The flexible tube can deform under the influence of external forces. Specifically, when the flexible tube is squeezed by the drive structure 124, the deformation of the flexible tube closes the internal flow channel, blocking the flow of gas. When the drive structure 124 releases the flexible tube, the flexible tube returns to its original shape without being affected by the external force, and the internal flow channel is fully or partially opened, allowing gas to pass through.

[0095] In this embodiment, further, Figure 4 、 Figure 5 and Figure 7 As shown, the drive structure 124 includes a first drive member 126 and a movable member 128. The movable member 128 is connected to the first drive member 126 and contacts the second ventilation tube 122. Thus, during operation of the drive structure 124, the first drive member 126 drives the movable member 128 to move, thereby controlling the opening area of the second ventilation tube 122.

[0096] Specifically, if Figure 4 、 Figure 5 and Figure 7 As shown, the first driving member 126 can be a motor, and the movable member 128 can be a cam. In this way, the motor can drive the cam to rotate, thereby causing the cam to press the second heat exchange tube, thereby causing the second air exchange tube 122 to deform to adjust the opening area.

[0097] Specifically, in the process of adjusting the opening area of the second ventilation pipe 122 , the cam can be driven by a motor to rotate an appropriate angle, so that the second ventilation pipe 122 is deformed to varying degrees, thereby controlling the opening area of the second ventilation pipe 122 .

[0098] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0099] The fourth embodiment of the present invention provides a cooking utensil 100, which further comprises:

[0100] like Figure 5 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 12 As shown, the cooking appliance 100 further includes a detection device 130. The detection device 130 is integrated with the ventilation box 110 and detects the temperature of food within the cooking cavity 104. Thus, the cooking appliance 100 of the present invention integrates detection, ventilation, and exhaust functions within the ventilation box 110, making the cooking appliance 100 compact and facilitating modular assembly.

[0101] Specifically, the detection device 130 may adopt a temperature sensor (for example, an infrared sensor), and detect the temperature of the food in the cooking cavity 104 through the temperature sensor.

[0102] In this embodiment, further, Figure 5 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 12 As shown, the cooking appliance 100 further includes a mounting structure 132, and the mounting structure 132 is located in the ventilation box 110. The detection device 130 is disposed on the mounting structure 132 to ensure that the detection device 130 is integrated into the ventilation box 110, thereby realizing a modular design of the cooking appliance 100.

[0103] In addition, if Figure 5 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 12 As shown, the mounting structure 132 is located on the side of the ventilation box 110 facing the cooking cavity 104 to ensure that the detection device 130 is installed toward the cooking cavity 104 , thereby enabling the detection device 130 to accurately detect the temperature of food in the cooking cavity 104 .

[0104] Specifically, if Figure 8 、 Figure 10 and Figure 11As shown, the steam flow channel 118 is located between the ventilation channel 120 and the mounting structure 132, so as to reasonably set the positions of the mounting structure 132, the steam flow channel 118 and the ventilation channel 120 on the ventilation box 110 to ensure that steam and external air will not affect the detection results of the detection device 130.

[0105] In this embodiment, mounting structure 132 and ventilation box 110 are integrated. That is, the present invention integrates mounting structure 132 with ventilation box 110, and uses mounting structure 132 to mount detection device 130. This allows the present invention to integrate ventilation, exhaust, and detection functions using ventilation box 110 as a carrier, making the cooking appliance 100 compact and facilitating modular assembly.

[0106] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0107] The fifth embodiment of the present invention provides a cooking utensil 100, which further comprises:

[0108] like Figure 7 As shown, the cooking appliance 100 further includes a heat dissipation duct 134, which is located within the ventilation box 110. The detection device 130 and at least a portion of the ventilation assembly 106 are located within the heat dissipation duct 134 (specifically, the drive structure 124 of the ventilation assembly 106 is located within the heat dissipation duct 134). Furthermore, the cooking appliance 100 further includes a heat dissipation device 136, which is disposed within the heat dissipation duct 134 and can supply air to the heat dissipation duct 134 during operation to dissipate heat from components within the heat dissipation duct 134.

[0109] Further, if Figure 7 and Figure 8 As shown, the detection device 130 and the driving structure 124 of the ventilation component 106 are both arranged inside the heat dissipation duct 134, so that the present invention can dissipate heat for the detection device 130 and the driving structure 124 of the ventilation component 106 at the same time through a heat dissipation device 136, effectively simplifying the heat dissipation related structure of the cooking appliance 100, and also helping to reduce the cost and assembly difficulty of the cooking appliance 100.

[0110] Specifically, during operation of the cooking appliance 100, the temperature of the detection device 130 and the drive structure 124 of the ventilation assembly 106 will rise to a certain extent. At this time, the heat dissipation device 136 operates and draws cool air from the external environment into the heat dissipation duct 134. This cool air is then directed through the detection device 130 and the drive structure 124 of the ventilation assembly 106, thereby controlling the temperature of the detection device 130 and the drive structure 124 of the ventilation assembly 106 and effectively cooling them.

[0111] In this embodiment, the heat dissipation duct 134 and the ventilation box 110 are integrated into one structure. That is, the present invention integrates the heat dissipation duct 134 with the ventilation box 110. This allows the present invention to integrate the heat dissipation function within the ventilation box 110, using the ventilation box 110 as a carrier. This facilitates a modular design for heat dissipation and ventilation, thereby simplifying the structure of the cooking appliance 100.

[0112] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0113] The sixth embodiment of the present invention provides a cooking utensil 100, which, based on the second, third, fourth and fifth embodiments, further comprises:

[0114] like Figure 2 As shown, ventilation box 110 also includes a box body 138 and a cover 140. The heat dissipation duct 134, steam flow channel 118, and ventilation channel 120 are located within box body 138, and cover 140 is mounted on box body 138. Furthermore, cover 140 is provided with a ventilation grille 146 to ensure communication between cooking cavity 104 and the external environment.

[0115] Specifically, the ventilation grille 146 can be made of plastic. In addition, the ventilation grille 146 can also be covered with a filter component (e.g., covered with a filter element) to further remove moisture and oil smoke in the air to avoid polluting the environmental sanitation of the environment where the cooking utensil 100 is located.

[0116] In this embodiment, further, Figure 3As shown, the cover 140 is detachably connected to the box body 138. In this way, during use, the user can remove the cover 140 to inspect the components inside the ventilation box 110, and it is also convenient for the user to clean the inside of the ventilation box 110 to ensure the cleanliness of the inside of the ventilation box 110 and the entire cooking utensil 100.

[0117] In this embodiment, further, Figure 4 As shown, the box body 138, heat dissipation duct 134, steam flow channel 118, and ventilation channel 120 are an integrated structure. Specifically, the heat dissipation duct 134, steam flow channel 118, and ventilation channel 120 can be directly manufactured during the manufacturing process of the ventilation box 110. This not only reduces the manufacturing difficulty of the ventilation box 110, but also simplifies the structure of the ventilation box 110, thereby avoiding the subsequent assembly process.

[0118] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0119] The seventh embodiment of the present invention provides a cooking utensil 100, which further comprises:

[0120] like Figure 2 As shown, the cooking appliance 100 further includes an air inlet (not shown) and an exhaust port (not shown). The air inlet is provided on the body 102, and the steam generating assembly is connected to the cooking cavity 104 via the air inlet, allowing steam generated by the steam generating assembly to enter from the top of the cooking cavity 104. Furthermore, an exhaust port is provided on the body 102, and an exhaust pipe 114 is connected to the cooking cavity 104 via the exhaust port. The exhaust port is arranged lower than the air inlet port to ensure that air in the cooking cavity 104 can be discharged from the bottom of the cooking cavity 104.

[0121] Specifically, during the operation of the steam generating assembly, the steam generating assembly may input steam into the cooking cavity 104 through the air inlet, and the steam entry position is higher than the position of the exhaust port.

[0122] In particular, the density of steam is greater than the density of the gas in the cooking cavity 104, causing the steam to form a steam layer after entering the cooking cavity 104. As the amount of steam increases, the steam layer continues to descend. The descending steam layer forces the air in the cooking cavity 104 to be discharged from the exhaust port, thereby reducing the oxygen content in the cooking cavity 104. The low-Reynolds oxygen removal technology using steam upwards allows for low-oxygen cooking for a period of time, reducing the generation of harmful substances in food.

[0123] In addition, the cooking utensil 100 proposed in this embodiment has all the beneficial effects of the cooking utensil 100 of the first embodiment, can integrate the ventilation function and the exhaust function on the ventilation box 110, and can change the oxygen content in the cooking cavity 104 to achieve variable oxygen cooking and anaerobic cooking, so as to enhance the cooking function of the cooking utensil 100 and enhance the cooking effect of food, which will not be discussed in detail here.

[0124] On the basis of the first to seventh embodiments, further, as Figure 1 As shown, the cooking appliance 100 also includes a fan assembly 142. Fan assembly 142 includes a second drive member (not shown) and a fan (not shown) connected to each other. The second drive member is capable of driving the fan to rotate. Furthermore, the fan of fan assembly 142 is located within the cooking cavity 104 and, when rotating, generates negative pressure within the cooking cavity 104, thereby allowing air from the external environment to enter the cooking cavity 104 through the ventilation assembly 106.

[0125] Specifically, the second driving member may be a motor, and the motor drives the fan to rotate.

[0126] On the basis of the first to seventh embodiments, further, as Figure 1 、 Figure 2 and Figure 3 As shown, the main body 102 further includes a back panel 144. The ventilation assembly 106 and the exhaust assembly 112 are integrated on the back panel 144. Thus, the cooking appliance 100 of the present invention achieves an integrated design of the ventilation assembly 106 and the exhaust assembly 112, simplifying the overall structure of the cooking appliance 100, facilitating its manufacture and assembly, as well as subsequent maintenance.

[0127] Specifically, during the assembly of the cooking appliance 100 , it is only necessary to install the back plate 144 to the inner pot of the cooking appliance 100 and connect the first ventilation duct 108 and the second ventilation duct 122 to the cooking cavity 104 .

[0128] On the basis of the first to seventh embodiments, further, as Figure 10As shown, the condensation drainer 116 includes a condensation chamber 150 and a flow guide component (not shown). The condensation chamber 150 is connected to the exhaust pipe 114 and the ventilation box 110, so that the steam in the cooking chamber 104 can enter the condensation chamber 150 through the exhaust pipe 114.

[0129] In addition, the guide component is connected to the condensation chamber 150 and the cooking chamber 104. The condensed water generated in the condensation chamber 150 can flow back to the cooking chamber 104 through the guide component, thereby collecting the condensed water and preventing the condensed water from contacting the relevant electrical control components of the cooking appliance 100.

[0130] Specifically, the flow guide member may be a flow channel structure, wherein the flow channel structure extends from the condensation chamber 150 to the interior of the cooking chamber 104, thereby guiding the condensed water generated in the condensation chamber 150 into the cooking chamber 104, thereby preventing the condensed water from flowing inside the cooking appliance, and reducing the possibility of failure of the electrical control components inside the cooking appliance.

[0131] Furthermore, a condensation component may be provided in the condensation chamber 150 to further enhance the condensation effect of the steam in the condensation chamber 150 .

[0132] Specifically, the condensing component can be a cooling fin or the like. That is, during operation of the cooking appliance, the cooling fin can further reduce the temperature in the condensing chamber 150, thereby improving the condensation effect of the steam in the condensing chamber 150 and further improving the fog-free effect of the cooking appliance during operation.

[0133] On the basis of the first to seventh embodiments, further, as Figure 5 and Figure 6 As shown, a ventilation port 148 is provided on the ventilation box 110 , and the first ventilation pipe 108 is connected to the ventilation channel 120 inside the ventilation box 110 through the ventilation port 148 .

[0134] In addition to the first through seventh embodiments, the cooking appliance further includes a microwave generating assembly (not shown) for providing microwaves within the cooking cavity 104. Thus, the cooking appliance 100 of the present invention can also cook food using microwave heating. The specific structure of the microwave generating assembly is not discussed in detail here, but will be readily understood by those skilled in the art.

[0135] In addition to the first through seventh embodiments, the cooking appliance further includes a heating tube (not shown) for providing heat to the cooking cavity 104. This allows the cooking appliance 100 of the present invention to also cook food by grilling. The specific structure of the heating tube is not discussed in detail here, but will be readily understood by those skilled in the art.

[0136] like Figure 1 As shown, based on the first to seventh embodiments, the cooking appliance 100 further includes but is not limited to the following products: a steamer, a microwave oven and a steamer-bake combination machine.

[0137] like Figure 1 and Figure 9 As shown, the eighth embodiment of the present invention provides a cooking utensil 100; wherein, Figure 2 and Figure 3 As shown, the exhaust pipe 114 guides the unused steam in the cooking cavity 104 into the condensation drain 116, condensing the steam and draining it, so that the steam outlet of the cooking device 100 is mist-free. The cooking device 100 drives the movable part 128 to control the opening and closing of the second ventilation pipe 122 to realize the variable oxygen function in the cooking cavity 104. The detection device 130 measures the temperature of the heated food to realize intelligent microwave heating. In addition, Figure 5 、 Figure 6 and Figure 7 As shown, the above functional structures are concentrated on the ventilation box 110, and a heat dissipation device 136 is used to dissipate heat from the entire box, thereby achieving a compact structure without losing any functions.

[0138] Specifically, if Figure 2 、 Figure 5 、 Figure 6 and Figure 7 As shown, the cooking appliance 100 proposed in the present invention uses the ventilation box 110 as the core carrier, integrates functional structures such as temperature detection, variable oxygen baking, and steam mist-free on the ventilation box 110, and shares a heat dissipation device 136 to realize a functional integration structure, making the structure compact and easy to assemble the whole machine modularly, making the structure of the cooking appliance 100 compact. Under the premise of ensuring the same function, the cooking appliance 100 proposed in the present invention has certain advantages of cost and easy assembly.

[0139] Specifically, the cooking appliance 100 proposed in the present invention includes an exhaust pipe 114, a condensation drain 116, a first ventilation pipe 108, a ventilation box 110, a detection device 130, a heat dissipation device 136, a first driving member 126, a movable member 128 and a second ventilation pipe 122 and other structures.

[0140] Specifically, if Figure 2 、 Figure 3 and Figure 4 As shown, the exhaust pipe 114 guides the steam in the cooking cavity 104 into the condensation drain 116, and the condensation drain 116 is connected to the steam flow channel 118 of the ventilation box 110, thereby exhausting the steam into the atmosphere to reduce the generation of fog.

[0141] Specifically, if Figure 2 、 Figure 3 and Figure 4As shown, the first ventilation pipe 108 is connected to the ventilation channel 120 of the ventilation box 110, and the ventilation channel 120 is connected to the external environment through the second ventilation pipe 122; the first driving member 126 is fixed on the ventilation box 110, and the first driving member 126 drives the movable member 128 to control the tightness of the second ventilation pipe 122, thereby controlling the connection and disconnection with the atmosphere, and finally achieving the purpose of oxygen change in the cooking cavity 104.

[0142] Specifically, if Figure 5 、 Figure 6 and Figure 10 As shown, the detection device 130 is placed on the mounting structure 132 of the ventilation box 110, so that the cooking appliance 100 has a temperature measurement function. Specifically, the detection device 130 can be an infrared sensor.

[0143] Specifically, if Figure 5 As shown, the ventilation box 110 is provided with a heat dissipation device 136, which can draw cold air into the heat dissipation duct 134, and then force air cooling on the detection device 130 and the detection device 130 to meet the temperature rise requirements of normal operation.

[0144] Specifically, when steam needs to be exhausted from cooking cavity 104, exhaust assembly 112 operates. The steam in cooking cavity 104 then flows through exhaust pipe 114 into condensate drain 116, where at least a portion of the steam condenses into condensed water. A small portion of the steam and air enters ventilation box 110 and is discharged to the outside environment through ventilation box 110. Thus, the cooperation between condensate drain 116 and ventilation box 110 enables mist-free exhaust from cooking appliance 100, preventing high-temperature steam from harming the user and preventing the steam from affecting other electrical devices around cooking appliance 100, making cooking appliance 100 safer to use.

[0145] Specifically, as the steam generating assembly discharges steam into the cooking cavity 104, as the amount of steam increases, the air originally in the cooking cavity 104 is discharged through the exhaust assembly 112, reducing the oxygen content in the cooking cavity 104. In this case, the cooking appliance 100 of the present invention can perform low-oxygen cooking, thereby reducing the generation of harmful substances in food.

[0146] Furthermore, while ventilation assembly 106 is operating, cooking appliance 100 can also re-introduce oxygen from the external environment into cooking cavity 104, allowing the food in cooking cavity 104 to fully undergo the Maillard reaction and improving the cooking quality. Thus, by integrating ventilation and exhaust functions within ventilation box 110, cooking appliance 100 according to the present invention can change the oxygen content in cooking cavity 104, achieving both variable-oxygen cooking and oxygen-free cooking, thereby enhancing the cooking function of cooking appliance 100 and improving the cooking quality of food.

[0147] Furthermore, when it is necessary to introduce outside air, the drive mechanism 124 opens the second ventilation duct 122, allowing air from the outside environment to enter the cooking cavity 104 through the second ventilation duct 122. While the food in the cooking cavity 104 is being cooked with steam, the drive mechanism 124 closes the second ventilation duct 122, preventing steam leakage from the cooking cavity 104.

[0148] Furthermore, the opening area of the second ventilation duct 122 can be controlled according to actual conditions. For example, when the volume of the cooking cavity 104 is large or when a large amount of food is being cooked, it is necessary for external air to quickly enter the cooking cavity 104, and the second ventilation duct 122 can be controlled to be fully open. When the volume of the cooking cavity 104 is small or when a small amount of food is being cooked, it is not necessary for external air to quickly enter the cooking cavity 104, and the second ventilation duct 122 can be controlled to be partially open. Specifically, the first driving member 126 can be a motor, and the movable member 128 can be a cam. When adjusting the opening area of the second ventilation duct 122, the motor can be used to drive the cam to rotate to an appropriate angle, causing the second ventilation duct 122 to deform to varying degrees, thereby controlling the opening area of the second ventilation duct 122.

[0149] Therefore, the cooking appliance 100 proposed by the present invention integrates temperature measurement, ventilation, and exhaust functions into the ventilation box 110. Using the ventilation box 110 as a carrier to achieve the integrated configuration of these different functions facilitates the modular design of the cooking appliance 100, simplifies the structural complexity of the cooking appliance 100, and facilitates its production and assembly. This, in turn, reduces the cost of the cooking appliance 100. Furthermore, the oxygen content within the cooking cavity 104 can be varied, enabling variable oxygen cooking and oxygen-free cooking, thereby enhancing the cooking function of the cooking appliance 100 and improving the cooking quality of food.

[0150] Furthermore, the cooking appliance 100 can dissipate heat from both the detection device 130 and the drive structure 124 of the ventilation assembly 106 via a single heat sink 136, effectively simplifying the heat dissipation-related structures of the cooking appliance 100 and reducing the cost and assembly difficulty of the cooking appliance 100. Specifically, the heat sink 136 can be a heat dissipation motor and a heat dissipation fan.

[0151] Furthermore, the cooking appliance 100 utilizes low-oxygen cooking technology with steam inlet for a period of time, reducing the production of harmful substances in food. Furthermore, fresh air can be introduced from the outside environment to change the oxygen content within the cooking cavity 104, allowing the food in the cooking cavity 104 to fully undergo the Maillard reaction, thereby improving the cooking effect.
