Description

Technical Field

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

[0002] What is provided in this part is only background information related to the present disclosure, and it is not necessarily prior art.

[0003] When a cooking appliance cooks food, the food is placed in the cooking cavity of the cooking appliance, and the food is cooked by heating the food.

[0004] During the cooking process of the food, the steam in the cooking cavity needs to be discharged. In the related art, in order to reduce the adverse effects on the user caused by the discharged steam (such as scalding the user, etc.), the air outlet is usually arranged at the rear of the cooking appliance. However, the discharged steam directly contacts the cabinet, which is likely to cause adverse effects on the cabinet (such as deformation or damage of the cabinet), thereby reducing the user experience. Summary of the Invention

[0005] The object of the present invention is to at least solve the problem of how to reduce the adverse effects of steam on the cabinet. This object is achieved by the following technical solutions:

[0006] The present application provides a cooking appliance, which includes:

[0007] A body, the body is provided with a cooking cavity and a heat dissipation air duct. The heat dissipation air duct is arranged outside the cooking cavity and is not connected to the cooking cavity. The heat dissipation air duct includes an air flow inlet and an air flow outlet, and the air flow inlet is connected to the outside;

[0008] An electrical component, the electrical component is arranged in the heat dissipation air duct. The heat dissipation component includes a heat dissipation fan and a functional device group. The heat dissipation fan is used to drive the outside air to enter the heat dissipation air duct through the air flow inlet and exchange heat with the functional device group, and is used to drive the air that has exchanged heat with the functional device group to flow out through the air flow outlet;

[0009] An exhaust component, the exhaust component includes a wind guide cover. The wind guide cover is installed on the body and includes an air inlet and an air outlet. The air inlet is respectively connected to the air flow outlet and the cooking cavity, and the air outlet is connected to the front side of the body. During the cooking process, the steam in the cooking cavity can enter the wind guide cover through the air inlet and be discharged through the air outlet and the front side of the body.

[0010] In the cooking appliance according to the present invention, during the cooking of food, the steam in the cooking cavity enters the air guide cover through the air inlet of the air guide cover. The heat dissipation fan operates, so that the outside air flows into the heat dissipation air duct through the air flow inlet of the heat dissipation air duct and exchanges heat with the functional device group. The air after heat exchange enters the air guide cover through the air outlet and the air inlet of the air guide cover and mixes with the steam in the air guide cover, and finally is discharged through the air outlet. Since the air outlet is connected to the front side of the body, the front-side discharge of the steam is realized, thereby reducing the adverse effect of the steam on the cabinet. At the same time, the heat dissipation air duct is connected to the air guide cover, so that the heat dissipation air flow can be mixed with the whole, thereby reducing the temperature of the steam and further reducing the situation of the steam scalding the user.

[0059] It should be understood that the terms used herein are for the purpose of describing specific exemplary embodiments only and are not intended to be limiting. Unless otherwise clearly specified in the context, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0062] As Figures 1 to 11 As shown, according to an embodiment of the present invention, a cooking appliance 100 is provided. The cooking appliance 100 includes a cavity assembly 13, an air intake assembly 30, a hot air assembly 50, and an exhaust assembly 40. The cavity assembly 13 defines a cooking cavity 131. The air intake assembly 30 is disposed outside the cooking cavity 131 and is connected to the cavity assembly 13. The air intake assembly 30 is configured to send external air into the cooking cavity 131. The hot air assembly 50 is disposed outside the cooking cavity 131 and is connected to the cavity assembly 13. The hot air assembly 50 is in communication with the cooking cavity 131. The hot air assembly 50 is at least configured to heat the cooking cavity 131 by circulating hot air when the air intake assembly 30 sends external air into the cooking cavity 131. The exhaust assembly 40 is disposed outside the cooking cavity 131 and is connected to the cavity assembly 13. The exhaust assembly 40 is configured to discharge the air in the cooking cavity 131 to the outside.

[0063] Specifically, the cavity assembly 13 includes a plurality of plate bodies. The plurality of plate bodies are spliced together, and the spliced plurality of plate bodies enclose the cooking cavity 131. When cooking food is required, the food is placed in the cooking cavity 131, and the food is cooked by heating to meet the user's usage requirements.

[0064] One end of the air intake assembly 30 is connected to the outside, and the other end is connected to the cooking cavity 131. Driven by the air intake assembly 30, outside air can enter the cooking cavity 131. After the outside air enters the cooking cavity 131 under the drive of the air intake assembly 30, the gas pressure in the cooking cavity 131 can be increased. After the gas pressure in the cooking cavity 131 increases, the driving force for the air flow to be discharged through the exhaust assembly 40 can be increased, so that the discharge speed of the air flow through the exhaust assembly 40 is increased.

[0065] The heating cavity of the hot air assembly 50 is connected to the cooking cavity 131. When the hot air assembly 50 operates, it can make the air flow circulate between the cooking cavity 131 and the heating cavity of the hot air assembly 50. When the hot air assembly 50 operates, it can only realize the circulation of the air flow between the heating cavity and the cooking cavity 131 without heating the air flow, or it can also make the air in the cooking cavity 131 enter the heating cavity to heat the air flow, and then send the heated air flow into the cooking cavity 131.

[0066] For the cooking appliance 100 according to the present invention, when cooking food and it is necessary to discharge steam, the air intake assembly 30 and the hot air assembly 50 are controlled to operate. The air intake assembly 30 sends outside air into the cooking cavity 131. After the outside air enters the cooking cavity 131, it can dilute the steam, and at the same time increase the gas pressure in the cooking cavity 131, so that the discharge speed of the steam in the cooking cavity 131 is increased. The hot air assembly 50 heats the air in the cooking cavity 131, so that the amount of steam in the cooking cavity 131 is reduced, thereby effectively reducing the influence of steam on the food cooking process, and further improving the cooking quality of the food, so that the user experience is improved.

[0067] In some embodiments of the present invention, the air intake assembly 30 includes an air intake fan 31 and an air guide pipe 32. The air intake port of the air intake fan 31 is connected to the outside, one end of the air guide pipe 32 is connected to the exhaust port of the air intake fan 31, and the other end of the air guide pipe 32 is connected to the cooking cavity 131.

[0068] Specifically, as Figure 1 shown, the cooking appliance 100 includes a body 10. The body 10 includes a cavity assembly 13, a door assembly 11 and a base assembly 12. Among them, the cavity assembly 13 is fixed on the top of the base assembly 12, the cavity assembly 13 encloses a cooking cavity 131, and the door assembly 11 is connected to the cavity assembly 13 and is used to open or close the cooking cavity 131.

[0069] The cavity assembly 13 includes a plurality of plate bodies and an outer cover 135. The plurality of plate bodies enclose to form a cooking cavity 131. The outer cover 135 covers the outside of the plurality of plate bodies. There is a space between the outer cover 135 and the outside of the plurality of plate bodies. The air inlet fan and the air guide pipe 32 are both arranged in this space. The air inlet fan 31 can be fixedly connected to the outer surface of the cavity assembly 13, or can be fixedly connected to the base assembly 12 of the body 10 of the cooking appliance 100. An air hole (such as a grille hole or a mesh hole structure, etc.) is formed in the outer cover 135. The air inlet of the air inlet fan 31 is arranged opposite to the air hole. The outlet of the air inlet fan 31 is connected to the cooking cavity 131 through the air guide pipe 32.

[0070] Among them, the connection mode between the air guide pipe 32 and the exhaust port of the fan includes but is not limited to plugging or connecting through a connecting piece. A connecting structure communicating with the cooking cavity 131 is provided on the cavity assembly 13. The connection mode between the air guide pipe 32 and the connecting structure includes but is not limited to plugging or connecting through a connecting piece. By providing the air guide pipe 32, the air inlet fan 31 can be effectively connected to the cooking cavity 131, so as to facilitate the reasonable layout and installation of the air inlet fan 31, thereby improving the overall structural compactness.

[0071] The air guide pipe 32 is a flexible pipe (such as a rubber or silicone pipe, etc.). The flexible pipe is convenient for setting and installation, can effectively improve the convenience of assembly, and thus can effectively improve the production rhythm, so that the production efficiency can be improved. Setting the air guide pipe 32 as a flexible pipe can make the air guide pipe 32 smoothly transition at the turning position, thereby reducing the blockage of the air flow and further reducing the influence on the air flow velocity.

[0072] It should be noted that in this application, the air inlet fan 31 is a centrifugal fan. The centrifugal fan has a high rotation speed and a better driving effect on the air flow, and can effectively increase the air flow input into the cooking cavity 131.

[0073] In addition, the air inlet fan 31 includes a fan body 311, a first bracket 312 and a second bracket 313. The top of the first bracket 312 is connected to the second bracket 313 (the connection mode includes but is not limited to clamping, bonding, welding or connecting through a connecting piece, etc.) and encloses to form an installation space. The fan body 311 is arranged in this installation space. At least one of the first bracket 312 and the second bracket 313 is fixed to the cavity assembly 13 or the base assembly 12. With such a setting, on the one hand, the fixing strength of the fan body 311 can be improved, so that the stability of the fan body 311 during operation can be improved. On the other hand, the first bracket 312 and the second bracket 313 can block the vibration of the fan body 311 during operation, reduce the transmission of the vibration of the fan body 311 during movement to other components, and can reduce the vibration and noise during the operation of the whole machine.

[0074] In some embodiments of the present invention, as Figure 8 and Figure 9 shown, the intake assembly 30 further includes a one-way valve 33 disposed in the air duct 32. The one-way valve 33 is configured to conduct unidirectionally in the direction from the intake fan 31 to the cooking cavity 131.

[0075] Specifically, the intake fan 31 is connected to the cooking cavity 131 through the air duct 32. Driven by the intake fan 31, external air enters the cooking cavity 131 through the air duct 32 to assist in discharging the steam in the cooking cavity 131.

[0076] By disposing the one-way valve 33 in the air duct 32 and using the one-way valve 33 to configure the air duct 32 into a unidirectionally conductive structure, the air flow can only conduct unidirectionally in the direction from the intake fan 31 to the cooking cavity 131, reducing the situation where the air flow in the cooking cavity 131 flows back through the air duct 32 (i.e., the situation where the air flow in the cooking cavity 131 enters the fan through the air duct 32), thereby reducing the adverse effects on components such as the intake fan 31 caused by the air flow backflow.

[0077] It should be understood that in the present application, the above one-way valve 33 is a general term for components that can achieve the unidirectional conduction function, that is, as long as it is a component that can achieve the unidirectional conduction function, it can be understood as the one-way valve 33 in the present application.

[0078] It should be noted that the one-way valve 33 is disposed in the air duct 32. Among them, the installation position of the one-way valve 33 can be the connection end of the air duct 32 and the intake fan 31, or the connection end of the air duct 32 and the cavity assembly 13, or the area between the two ends of the air duct 32.

[0079] In some embodiments of the present invention, as Figure 9 shown, the one-way valve 33 includes a valve seat and a valve core 333. The valve seat is fixed in the air duct 32. The valve seat is provided with a gas passage. The valve core 333 is movably disposed on the valve seat. Along the direction from the intake fan 31 to the cooking cavity 131, the valve core 333 can move relative to the valve seat and open the gas passage.

[0080] Specifically, the valve seat is fixed inside the air guide pipe 32. At the position of the valve seat, the air guide pipe 32 can only communicate through the gas passage on the valve seat. The valve core 333 is arranged on the valve seat and can move relative to the valve seat. The valve core 333 keeps the gas passage on the valve seat in a closed state. When the intake fan 31 drives the outside air into the air guide pipe 32, the incoming air flow acts on the valve core 333, causing the valve core 333 to move relative to the valve seat, thereby opening the gas passage so that the air flow can enter the cooking cavity 131 through the air guide pipe 32. After the intake fan 31 is turned off, there is no outside air flow in the air guide pipe 32, the acting force on the valve core 333 is released, and the valve core 333 moves relative to the valve seat and closes the gas passage.

[0081] By using the cooperation between the valve core 333 and the valve seat, the one-way conduction of the air guide pipe 32 is effectively realized. The structure of the one-way valve 33 is simple, which can effectively reduce the manufacturing cost.

[0082] It should be noted that, as Figure 9 shown, the valve seat includes a first part 331 and a second part 334. Among them, both the first part 331 and the second part 334 are cylindrical parts. A bracket with a sliding hole is arranged inside the cylinder of the first part 331, and a limiting ring with a through hole is arranged inside the cylinder of the second part 334. The first part 331 is sleeved and fixed on the outside of the second part 334 (wherein, the fixing methods include but are not limited to clamping, bonding, welding or connecting through connecting parts, etc.). The first part 331 and the second part 334 enclose a gas passage, and the gas passage communicates with the outside through the through hole on the limiting ring. The valve core 333 is arranged in the gas passage and includes a connected connecting rod part and a blocking part. The connecting rod part passes through the sliding hole. By the sliding of the connecting part relative to the sliding hole, the blocking part can move towards or away from the limiting ring. When the intake is closed, the blocking part abuts against one side of the limiting ring facing the bracket and closes the through hole. When the intake fan 31 passes the outside air into the air guide pipe 32, the air flow acts on the blocking part through the through hole, causing the blocking part and the connecting part to slide relative to the sliding hole of the bracket, so that the blocking part is separated from the limiting ring, so as to open the through hole, and further realize the conduction of the one-way valve 33. After the intake fan 31 is turned off, there is no outside air flow in the air guide pipe 32, the acting force on the valve core 333 is released, and the blocking part and the connecting part slide reversely relative to the sliding hole of the bracket, so that the blocking part abuts against the limiting ring, so as to close the through hole.

[0083] In some embodiments of the present invention, as Figure 9 shown, the one-way valve 33 further includes an elastic member 332. The elastic member 332 cooperates with the valve seat and the valve core 333 respectively, and the restoring force of the elastic member 332 drives the valve core 333 to have a tendency to close the gas passage.

[0084] Specifically, the valve core 333 is arranged on the valve seat of the one-way valve 33 and can move relative to the valve seat. When the intake fan 31 is operating, the valve core 333 moves relative to the valve seat and releases the closing of the gas passage, so that the one-way valve 33 is opened, thereby enabling external air to enter the cooking cavity 131 through the air guide pipe 32. After the intake fan 31 is closed, the valve core 333 moves relative to the valve seat and closes the gas passage, so that the one-way valve 33 is closed, thereby reducing the backflow of the air flow in the cooking cavity 131.

[0085] The elastic member 332 is respectively matched with the valve core 333 and the valve seat. After assembly, the elastic member 332 is in an elastic deformation state. The elastic member 332 in the elastic deformation state has a resilience force, and the resilience force acts on the valve core 333, so that the valve core 333 is matched with the valve seat to facilitate the gas passage on the valve seat. By arranging the elastic member 332, the valve core 333 has a better closing effect on the gas passage, and further reduces the backflow of the air flow in the cooking cavity 131 through the air guide pipe 32.

[0086] It should be understood that the elastic member 332 can be a spring or an elastic sheet, etc.

[0087] In the present application, the elastic member 332 can be a spring. The valve seat includes a first part 331 and a second part 334. Among them, both the first part 331 and the second part 334 are cylindrical parts. A bracket with a sliding hole is arranged in the cylinder of the first part 331, and a limiting ring with a through hole is arranged in the cylinder of the second part 334. The first part 331 is sleeved and fixed on the outside of the second part 334 (wherein, the fixing methods include but are not limited to clamping, bonding, welding or connecting through a connecting member, etc.). The first part 331 and the second part 334 enclose a gas passage, and the gas passage is communicated with the outside through the through hole on the limiting ring. The valve core 333 is arranged in the gas passage and includes a connected connecting rod part and a blocking part. The connecting rod part is arranged in the sliding hole. By the sliding of the connecting part relative to the sliding hole, the blocking part can move in a direction close to or away from the limiting ring. When the intake is closed, the blocking part abuts against one side of the limiting ring facing the bracket and closes the through hole. The spring is sleeved on the connecting rod part. One end of the spring abuts against the bracket, and the other end of the spring abuts against the blocking part. The spring is in an elastic deformation state and has a resilience force, and the resilience force acts on the blocking part, so that the blocking part abuts against the limiting ring, thereby keeping the through hole in a closed state.

[0088] In some embodiments of the present invention, as Figures 7 to 9 shown, the air guide pipe 32 includes a vertical section 321. The one-way valve 33 is arranged in the vertical section 321. The gravity of the valve core 333 and the resilience force of the elastic member 332 drive the valve core 333 to have a tendency to close the gas passage.

[0089] Specifically, the air duct 32 includes a vertical section 321. The vertical section 321 is vertically arranged. The air duct 32 has a structure with air intake at the bottom (the end connected to the intake air blower 31) and air outlet at the top (the end connected to the cooking cavity 131) at the position of the vertical section 321. The one-way valve 33 is arranged in the vertical section 321. The valve body is fixed to the pipe wall of the air duct 32. The gas passage is formed in the valve body. The valve core 333 is arranged in the gas passage and can move relative to the gas passage. The elastic member 332 is respectively engaged with the valve core 333 and the valve seat. After being assembled, the elastic member 332 has a resilience force. The valve core 333 has gravity. Driven by the resilience force and gravity, the valve core 333 keeps the gas passage in a closed state.

[0090] When the intake air blower 31 drives the outside air into the air duct 32, the incoming air flow acts on the valve core 333, causing the valve core 333 to move relative to the valve seat after overcoming its own gravity and the resilience force of the elastic member 332, so as to open the gas passage, allowing the air flow to enter the cooking cavity 131 through the air duct 32. When the intake air blower 31 is turned off, there is no outside air flow in the air duct 32, and the acting force on the valve core 333 is released. The resilience force of the elastic member 332 and the gravity of the valve core 333 drive the valve core 333 to move relative to the valve seat and close the gas passage.

[0091] By arranging the one-way valve 33 in the vertical section 321 of the air duct 32, the gravity of the valve core 333 itself can be used to keep the valve core 333 in the state of closing the gas passage. Through cooperation with the elastic member 332, the closing effect of the valve core 333 on the gas passage can be improved, thereby enhancing the one-way function of the one-way valve 33, and further reducing the situation of gas in the cooking cavity 131 flowing back through the air duct 32.

[0092] It should be noted that in this application, the air duct 32 further includes a horizontal section 322. The intake air blower 31 is connected to the vertical section 321 through the horizontal section 322, and the horizontal section 322 is smoothly connected to the vertical section 321.

[0093] In some embodiments of the present invention, the cavity assembly 13 includes a first plate body 137. The first plate body 137 constitutes part of the cooking cavity 131. An air outlet area and an air inlet area are respectively provided on the first plate body 137. The hot air assembly 50 includes a hot air hood, a heating element and a heating blower. The hot air hood is connected to the first plate body 137 and encloses a heating cavity. The heating cavity is respectively connected to the cooking cavity 131 through the air inlet area and the air outlet area. The heating element is arranged in the heating cavity and located between the air outlet area and the air inlet area. The heating blower includes an impeller. The impeller is rotatably arranged in the heating cavity. Driven by the impeller, the air in the cooking cavity 131 enters the heating cavity through the air outlet area and is heated by the heating element. The air flow heated by the heating element enters the cooking cavity 131 through the air inlet area.

[0094] Specifically, the cavity assembly 13 includes a plurality of plate bodies, and the plurality of plate bodies are spliced and connected (the connection methods include but are not limited to welding, bonding, snap connection, or connection via a connecting member, etc.) to enclose a cooking cavity 131. Among them, the shape of the cooking cavity 131 includes but is not limited to a rectangle or a sphere, etc.

[0095] In the present application, the shape of the cooking cavity 131 is a rectangular structure. The cooking cavity 131 includes a top wall, a bottom wall, a rear side wall, a left side wall, and a right side wall. Among them, the first plate body 137 constitutes a part of the cooking cavity 131. The first plate body 137 can constitute one of the top wall, the bottom wall, the rear side wall, the left side wall, and the right side wall. For example, the first plate body 137 constitutes the rear side wall of the cooking cavity 131.

[0096] The hot air hood is connected to the side of the first plate body 137 facing away from the cooking cavity 131, and the hot air hood and the first plate body 137 enclose a heating cavity. The air inlet area (such as a grid structure or a mesh structure) and the air outlet area (such as a grid structure or a mesh structure) on the first plate body 137 are respectively connected to the heating cavity. The air inlet area and the air outlet area are spaced apart from each other (the spacing distance can ensure that the two airflows in the air inlet area and the air outlet area do not affect each other). The heating element and the impeller of the heating fan are both arranged in the heating cavity. Among them, the axis of the impeller is coaxially arranged with the air outlet area. In addition, the heating element (quartz tube, metal heating tube, graphite heating tube, etc.) is arranged in a ring shape on the radial outer side of the impeller. The impeller is a centrifugal impeller. After the impeller rotates, the air in the cooking cavity 131 leaves the cooking cavity 131 through the air outlet area and enters the impeller along the radial direction of the impeller. The airflow entering the impeller is thrown out in the radial direction of the impeller. The thrown-out airflow is heated by the heating element and then flows out through the air outlet area and enters the cooking cavity 131 through the air outlet area to provide hot air flow for the cooking cavity 131.

[0097] It should be understood that during the cooking process of food, the hot air assembly 50 can operate independently to heat and cook the food in the cooking cavity 131 through hot air flow.

[0098] When cooking food and it is necessary to discharge steam, control the intake air assembly 30 and the hot air assembly 50 to operate. The intake air assembly 30 sends external air into the cooking cavity 131. After the external air enters the cooking cavity 131, it can dilute the steam and at the same time increase the pressure of the gas in the cooking cavity 131, so that the discharge speed of the steam in the cooking cavity 131 is increased. The hot air assembly 50 heats the air in the cooking cavity 131, so that the amount of steam in the cooking cavity 131 is reduced, thereby effectively reducing the influence of steam on the food cooking process, and further improving the cooking quality of the food and enhancing the user experience.

[0099] In some embodiments of the present invention, such asFigure 5 and Figure 6 As shown in Figure 6 , the cavity assembly 13 includes a second plate body 136. The second plate body 136 forms part of the cooking cavity 131. The second plate body 136 is connected to or spaced from the first plate body 137. An air inlet is formed on the second plate body 136. The air inlet assembly 30 is connected to the cooking cavity 131 through the air inlet.

[0100] Specifically, the cavity assembly 13 includes a plurality of plate bodies. The plurality of plate bodies are spliced and connected (the connection methods include but are not limited to welding, bonding, snap connection or connection through connecting members, etc.) to enclose the cooking cavity 131. The first plate body 137 and the second plate body 136 respectively form part of the cooking cavity 131. Among them, the first plate body 137 is connected to the second plate body 136 or the two are spaced apart.

[0101] Among them, a hot air assembly 50 is provided on the side of the first plate body 137 facing away from the cooking cavity 131. The hot air hood and the side of the first plate body 137 facing away from the cooking cavity 131 enclose a hot air cavity. The hot air cavity is connected to the cooking cavity 131 through the air inlet area and the air outlet area on the first plate body 137. The impeller of the heat dissipation fan 21 is coaxially arranged with the air outlet area. The heating element is arranged around the radial outside of the impeller. After the impeller rotates, the air in the cooking cavity 131 leaves the cooking cavity 131 through the air outlet area and enters the impeller along the radial direction of the impeller. The air flow entering the impeller is thrown out in the radial direction of the impeller. The thrown air flow is heated by the heating element and then flows out through the air outlet area and enters the cooking cavity 131 to provide hot air flow for the cooking cavity 131.

[0102] One end of the air duct 32 of the air inlet assembly 30 is connected to the exhaust port of the air inlet fan 31. The other end of the air duct 32 is connected to the connection structure on the second plate body 136 so that the air duct 32 is connected to the air flow inlet on the second plate body 136. When the air inlet fan 31 operates, outside air enters the air duct 32, and the air flow in the air duct 32 enters the cooking cavity 131 through the air flow inlet.

[0103] By arranging the air flow inlet on the second plate body 136, the air flow of the air flow inlet is reduced from interfering with the air inlet area and the air outlet area on the first plate body 137, and further affecting the air flow in the cooking cavity 131 adversely.

[0104] In some embodiments of the present invention, the cavity assembly 13 includes a first plate body 137 and a second plate body 136. The first plate body 137 is connected to the second plate body 136 at an angle or spaced apart. The hot air assembly 50 is connected to the first plate body 137 and is connected to the cooking cavity 131. The exhaust assembly 40 is connected to the second plate body 136 and is connected to the cooking cavity 131.

[0105] Specifically, the cavity assembly 13 includes a plurality of plate bodies, and the plurality of plate bodies are spliced and connected (the connection methods include but are not limited to welding, bonding, snap connection, or connection through connecting pieces, etc.) to enclose a cooking cavity 131. The first plate body 137 and the second plate body 136 respectively form part of the cooking cavity 131, wherein the first plate body 137 and the second plate body 136 are connected at an angle or are spaced apart from each other.

[0106] Among them, a hot air assembly 50 is provided on the side of the first plate body 137 facing away from the cooking cavity 131. The hot air hood and the side of the first plate body 137 facing away from the cooking cavity 131 enclose a hot air cavity, and the hot air cavity is connected to the cooking cavity 131 through an air inlet area and an air outlet area on the first plate body 137. The impeller of the heat dissipation fan 21 is coaxially arranged with the air outlet area, and the heating element is arranged in a ring shape on the radial outside of the impeller. After the impeller rotates, the air in the cooking cavity 131 leaves the cooking cavity 131 through the air outlet area and enters the impeller along the radial direction of the impeller. The airflow entering the impeller is thrown out in the radial direction of the impeller, and the thrown airflow is heated by the heating element and then flows out through the air outlet area and enters the cooking cavity 131 to provide hot airflow for the cooking cavity 131.

[0107] One end of the exhaust pipe 42 of the exhaust assembly 40 is connected to the connection structure of the second plate body 136 and is connected to the cooking cavity 131. The other end of the exhaust pipe 42 is connected to the air guide hood 41, so that the cooking cavity 131 is connected to the air guide hood 41 through the exhaust pipe 42 and is connected to the outside through the air guide hood 41. By arranging the exhaust assembly 40 and the hot air assembly 50 on different plate bodies, the airflow interference of the hot air assembly 50 on the exhaust assembly 40 is reduced, and thus the exhaust assembly 40 can effectively exhaust the cooking cavity 131 to improve the exhaust effect.

[0108] One end of the air guide pipe 32 of the air intake assembly 30 is connected to the exhaust port of the air intake fan 31, and the other end of the air guide pipe 32 is connected to the connection structure on the second plate body 136 (the connection position of the air guide pipe 32 and the second plate body is spaced from the connection position of the exhaust assembly 40 and the second plate body 136), so that the air guide pipe 32 is connected to the air inlet on the second plate body 136. When the air intake fan 31 operates, outside air enters the air guide pipe 32, and the airflow in the air guide pipe 32 enters the cooking cavity 131 through the air inlet. By arranging the air inlet on the second plate body 136, the airflow at the air inlet is prevented from interfering with the air inlet area and the air outlet area on the first plate body 137, which may otherwise have an adverse impact on the airflow in the cooking cavity 131.

[0109] In some embodiments of the present invention, the cooking appliance 100 further includes a heating assembly, which is connected to the cavity assembly 13 and is used to heat the ingredients in the cooking cavity 131.

[0110] Specifically, the heating component includes, but is not limited to, a microwave heating device, a thermal radiation device, a high-temperature steam generating device, etc. When heating food, the heating component can be operated to heat the food in the cooking cavity 131, thereby effectively realizing the cooking of the food.

[0111] In some embodiments of the present invention, the exhaust component 40 includes an exhaust pipe 42 and a wind guide cover 41. One end of the exhaust pipe 42 is connected to the cooking cavity 131, the inlet of the wind guide cover 41 is connected to the other end of the exhaust pipe 42, and the outlet of the wind guide cover 41 is connected to the outside.

[0112] Specifically, during the cooking process of food, steam is generated in the cooking cavity 131. The steam enters the wind guide cover 41 through the exhaust pipe 42, and finally the steam is uniformly discharged through the wind guide cover 41. By providing the exhaust pipe and the wind guide cover 41, the discharge of steam is guided, so that the steam is discharged along a preset path, reducing the situation where the steam is discharged without permission, scalding the user or damaging components such as the cabinet.

[0113] In some embodiments of the present invention, the cooking appliance 100 further includes a control component. The control component includes a temperature acquisition component, a humidity acquisition component, and a control device. The temperature acquisition component is disposed in the cooking cavity 131 and is used to acquire the temperature in the cooking cavity 131. The humidity acquisition component is disposed in the cooking cavity 131 and is used to acquire the humidity in the cooking cavity 131. The control device is electrically connected to the temperature acquisition component, the humidity acquisition component, the intake component 30, and the hot air component 50 respectively.

[0114] Specifically, the stability acquisition component and the humidity acquisition component respectively acquire the temperature and humidity in the cooking cavity 131. The control device controls the intake component 30 and the hot air component 50 according to the acquired temperature and humidity data, so that the temperature and humidity in the cooking cavity 131 are maintained within the range required for cooking, thereby effectively improving the cooking effect of the food.

[0115] It should be noted that, in this application, the temperature acquisition component is a temperature sensor, and the humidity acquisition component is a humidity sensor.

[0116] In some embodiments of the present invention, such as Figure 1 Furthermore Figure 2As shown in the figure, the cooking appliance 100 includes a body 10, an electrical component 20, and an exhaust component 40. The body 10 is provided with a cooking cavity 131 and a heat dissipation air duct 121. The heat dissipation air duct 121 is arranged outside the cooking cavity 131 and is not in communication with the cooking cavity 131. The heat dissipation air duct 121 includes an air flow inlet and an air flow outlet. The air flow inlet is in communication with the outside. The electrical component 20 is arranged in the heat dissipation air duct 121. The heat dissipation component includes a heat dissipation fan 21 and a functional device group 22. The heat dissipation fan 21 is used to drive the outside air to enter the heat dissipation air duct 121 through the air flow inlet and exchange heat with the functional device group 22, and is used to drive the air after exchanging heat with the functional device group 22 to flow out through the air flow outlet. The exhaust component 40 includes a wind guide cover 41. The wind guide cover 41 is installed on the body 10 and includes an air inlet 412 and an air outlet 411. The air inlet 412 is respectively in communication with the air flow outlet and the cooking cavity 131. The air outlet 411 is in communication with the front side of the body 10. During the cooking process, the steam in the cooking cavity 131 can enter the wind guide cover 41 through the air inlet 412 and be discharged through the air outlet 411 and the front side of the body 10.

[0117] Specifically, the power device group in the electrical component includes but is not limited to a controller, a circuit board, a transformer, an inverter, a magnetron, etc. When the cooking appliance 100 operates, the power device group generates heat. In order to maintain the working temperature of the power device group at the required temperature condition, the heat dissipation fan 21 operates, so that the outside air enters the heat dissipation air duct 121. The air flow entering the heat dissipation air duct 121 exchanges heat with the power device group when passing through the power device group, so that the temperature of the power device group is reduced. The air flow after exchanging heat with the power device group is discharged through the heat dissipation air duct 121.

[0118] The exhaust component 40 includes a wind guide cover 41. The heat dissipation air duct 121 and the cooking cavity 131 are respectively in communication with the concave air inlet 412. The air flow discharged from the heat dissipation air duct 121 enters the wind guide cover 41 and is discharged through the 411 of the wind guide cover 41. When the air flow flows from the air inlet 412 of the wind guide cover 41 to the air outlet 411, a negative pressure is generated at the communication position between the wind guide cover 41 and the cooking cavity 131. Under the influence of this negative pressure, the wind guide cover 41 will suck the cooking cavity 131, so as to improve the discharge rate of the steam in the cooking cavity 131 and enable the steam in the cooking cavity 131 to be quickly discharged.

[0119] During the cooking process of food, the steam in the cooking cavity 131 enters the air guide cover 41 through the air inlet of the air guide cover 41. The heat dissipation fan 21 operates, causing the outside air to flow into the heat dissipation air duct 121 through the air inlet of the heat dissipation air duct 121 and exchange heat with the functional device group 22. The air after heat exchange enters the air guide cover 41 through the air outlet and the air inlet of the air guide cover 41 and mixes with the steam in the air guide cover 41, and finally is discharged through the air outlet. Since the air outlet is connected to the front side of the body 10 (in this application, the side facing the user of the cooking appliance 100 is the front side), the front-side discharge of steam is realized, reducing the adverse effects of steam on the cabinet. At the same time, the heat dissipation air duct 121 is connected to the air guide cover 41, enabling the heat dissipation air flow to mix with the steam, thereby reducing the temperature of the steam and further reducing the situation of steam scalding the user.

[0120] It should be understood that the steam source in the cooking cavity 131 includes but is not limited to the moisture evaporated from food during the cooking process, as well as the excess steam during the steam cooking mode, etc.

[0121] In some embodiments of the present invention, such as Figure 5 , Figure 6 , Figure 10 and Figure 11 shown, the exhaust assembly 40 further includes an exhaust pipe 42. One end of the exhaust pipe 42 is connected to the cooking cavity 131, and the other end of the exhaust pipe 42 is connected to the air inlet of the air guide cover 41.

[0122] Specifically, the cooking cavity 131 is connected to the air guide cover 41 through the exhaust pipe 42. Among them, one end of the exhaust pipe 42 is connected to the connecting part of the cavity assembly 13 (such as a plug structure, and the connection method between the exhaust pipe 42 and the connecting part includes but is not limited to plugging or connecting through a connecting piece), so that the exhaust pipe 42 is connected to the cooking cavity 131, and the other end of the exhaust pipe 42 is connected to the air guide cover 41 (the connection method between the air guide pipe 32 and the air guide cover 41 includes but is not limited to plugging or connecting through a connecting piece). By providing the exhaust pipe 42, the air guide cover 41 can be effectively connected to the cooking cavity 131, facilitating the reasonable layout and installation of the air guide cover 41, thereby improving the overall structural compactness.

[0123] The exhaust pipe 42 is a flexible pipe (such as a rubber or silicone tube, etc.). The flexible pipe is convenient for setting and installation, can effectively improve the assembly convenience, thereby effectively improving the production rhythm and enabling the production efficiency to be improved. Setting the exhaust pipe 42 as a flexible pipe enables the exhaust pipe 42 to have a smooth transition at the turning position, thereby reducing the blockage of the air flow and further reducing the influence on the air flow velocity.

[0124] In some embodiments of the present invention, such as Figure 3As shown, the cooking cavity 131 includes an air inlet hole 132 and an exhaust hole 133. The other end of the air guide tube 32 is connected to the cooking cavity 131 through the air inlet hole 132, and one end of the exhaust pipe 42 is connected to the cooking cavity 131 through the exhaust hole 133. The opening area of ​​the air inlet hole 132 is larger than the opening area of ​​the exhaust hole 133.

[0125] Specifically, the cavity assembly 13 includes a plurality of plates, which are spliced ​​and connected (connection methods include but are not limited to welding, bonding, clamping or connection via connectors, etc.) and surround a cooking cavity 131. The plurality of plates include a first plate 137 and a second plate 136. The first plate 137 and the second plate 136 respectively constitute part of the cooking cavity 131, wherein the first plate 137 is connected to the second plate 136 or the two are arranged at an interval.

[0126] In the present application, the cooking cavity 131 is a rectangular structure, and the first plate body 137 is connected to the second plate body 136, wherein the first plate body 137 constitutes the rear side wall of the cooking cavity 131, and the second plate body 136 constitutes the left wall or the right wall of the cooking cavity 131, and the hot air assembly 50 cooperates with the side of the first plate body 137 away from the cooking cavity 131 and is connected to the cooking cavity 131 through the air inlet area and the air outlet area on the first plate body 137, and an air inlet hole 132 and an exhaust hole 133 are opened on the second plate body 136, the air inlet hole 132 is connected to the air duct 32 of the air inlet assembly 30, and the exhaust hole 133 is connected to the exhaust pipe 42 of the exhaust assembly 40.

[0127] Among them, the opening area of ​​the air inlet 132 is larger than the opening area of ​​the exhaust hole 133, so that the air intake volume in the cooking cavity 131 is larger than the exhaust volume of the cooking cavity 131, so that a pressure accumulation process can be formed in the cooking cavity 131 to increase the air pressure in the cooking cavity 131, and then the pressure of the exhaust process is increased by increasing the air pressure in the cooking cavity 131, so that the exhaust rate is increased, so as to improve the exhaust efficiency of the steam in the cooking cavity 131.

[0128] It should be understood that the shape of the air inlet 132 includes but is not limited to a circular hole, an elliptical hole or a polygonal hole, and the shape of the air outlet 133 includes but is not limited to a circular hole, an elliptical hole or a polygonal hole.

[0129] It should be pointed out that the opening area of ​​the air inlet hole 132 is larger than the opening area of ​​the exhaust hole 133, wherein the ratio of the opening area of ​​the air inlet hole 132 to the opening area of ​​the exhaust hole 133 can be 1.2:1, 1.5:1, 2:1, 2.5:1, 3:1, 3.5:1, 4:1, 4.5:1, 5:1.

[0130] In some embodiments of the present invention, the ratio of the opening area of ​​the air inlet 132 to the opening area of ​​the air outlet 133 is 2:1.

[0131] With such a setting, the ratio of the opening area of the air inlet hole 132 to the opening area of the air outlet hole 133 is set to 2:1, so that a micro-pressure air field can be formed in the cooking cavity 131, which can reduce the adverse impact of pressure increase on the cooking process while increasing the steam discharge rate, and thus can effectively improve the cooking quality of food.

[0132] It should be noted that the inner diameter of the exhaust pipe 42 can be a uniform structure or a variable-diameter structure. When the inner diameter of the exhaust pipe 42 is a variable-diameter structure, the flow cross-section of the exhaust pipe 42 is set to decrease in the direction from the cooking cavity 131 to the air guide cover 41.

[0133] In some embodiments of the present invention, as Figure 10 and Figure 11 shown, the exhaust pipe 42 includes a connected first pipe section 421 and a second pipe section 422. The first pipe section 421 is connected to the cooking cavity 131, and the second pipe section 422 is connected to the air inlet of the air guide cover 41. The diameter of the first pipe section 421 is larger than the diameter of the second pipe section 422.

[0134] Specifically, by setting the first pipe section 421 and the second pipe section 422 and setting the diameters of the first pipe section 421 and the second pipe section 422 respectively, the flow cross-section of the exhaust pipe 42 is set to decrease in the direction from the cooking cavity 131 to the air guide cover 41. Then, when the air flow flows from the first pipe section 421 to the second pipe section 422, the flow cross-section decreases, increasing the pressure of the air flow, thereby increasing the flow velocity of the air flow and enabling the air flow to increase the discharge rate.

[0135] In some embodiments of the present invention, the ratio of the diameter of the first pipe section 421 to the diameter of the second pipe section 422 is 3:2.

[0136] With such a setting, the ratio of the diameter of the first pipe section 421 to the diameter of the second pipe section 422 is set to 3:2, so that a pressure accumulation structure can be formed in the exhaust pipe 42, which can reduce the impact on the air flow rate while increasing the steam discharge rate, and further improve the steam discharge effect.

[0137] In some embodiments of the present invention, as Figure 3 、 Figure 10 and Figure 11 shown, the flow cross-section of the air guide cover 41 is set to decrease in the direction from the air inlet to the air outlet.

[0138] Specifically, the air inlets 412 of the air guide cover 41 are respectively communicated with the heat dissipation air duct 121 and the cooking cavity 131. The air flow in the heat dissipation air duct 121 and the steam in the cooking cavity 131 both enter the air guide cover 41. Along the direction from the air inlet 412 to the air outlet 411, the flow cross-section of the air guide cover 41 is set to be decreasing. This can enable the steam to be evenly mixed with the air flow discharged from the heat dissipation air duct 121, thereby reducing the temperature of the discharged gas. At the same time, the reduction of the flow cross-section increases the pressure of the air flow, which can increase the flow velocity of the air flow and enable the air flow to increase the discharge rate.

[0139] In some embodiments of the present invention, as Figure 1 and Figure 3 shown, the body 10 includes a cavity assembly 13, a base assembly 12, and a door assembly 11. The cavity assembly 13 encloses a cooking cavity 131. The cavity assembly 13 includes a front plate 134. The front plate 134 is provided with a pick-up and placement opening 1341, and the pick-up and placement opening 1341 is communicated with the cooking cavity 131. The cavity assembly 13 is installed on the top of the base assembly 12. The heat dissipation air duct 121 is formed in the base assembly 12. The door assembly 11 is connected to the front plate 134 and is used to open or close the pick-up and placement opening 1341. In the state where the door assembly 11 closes the pick-up and placement opening 1341, the door assembly 11 is flush with the base assembly 12. Along the arrangement direction of the base assembly 12 and the cavity assembly 13, there is a spaced space 14 between the door assembly 11 and the base assembly 12. The air outlet of the air guide cover 41 is communicated with the spaced space 14.

[0140] Specifically, by setting the air outlet 411 of the air guide cover 41 to be communicated with the spaced space 14, the hidden setting of the steam discharge position can be realized, and thus the appearance coordination of the whole machine can be improved.

[0141] In addition, when the steam is discharged through the air outlet 411 of the air guide cover 41 and enters the spaced space 14, when the steam flows along the spaced space 14, it can contact the outside air, further reducing the temperature of the steam and further reducing the occurrence of the situation of scalding users.

[0142] In some embodiments of the present invention, the air inlet of the heat dissipation air duct 121 is opened at the bottom of the base assembly 12.

[0143] Specifically, by opening the air inlet of the heat dissipation air duct 121 at the bottom of the base assembly 12, the structure of bottom air intake of the heat dissipation air duct 121 is realized, reducing the situation that external foreign objects enter the heat dissipation air duct 121 through the air inlet, and further reducing the occurrence of the situation of power device group failure caused by foreign objects entering the heat dissipation air duct 121.

[0144] It should be noted that in the present application, the base assembly 12 includes a base body and a water box. The cavity assembly 13 is fixed to the base body, and a heat dissipation air duct 121 is formed on the base body. The air guide cover 41, the power device group, and the heat dissipation fan 21 are all installed on the base body. With such an arrangement, the installation of the air guide cover 41, the power device group, and the heat dissipation fan 21 by the base body can reduce the space occupied by the air guide cover 41, the power device group, and the heat dissipation fan 21 in other positions of the cooking appliance 100, and improve the space utilization rate of the whole machine.

[0145] The power device group is arranged on the base body, which can reduce the adverse effect of the heat during the cooking process in the cooking cavity 131 on the power device group, and thus reduce the failure rate of the cooking appliance 100.

[0146] In addition, the base body can be a metal part or a non-metal part. In the present application, the base body is a plastic part, which can not only reduce the manufacturing cost, but also effectively block the heat of the cooking appliance 100, reducing the damage of components such as the cabinet caused by the heat transfer through the base body.

[0147] Furthermore, the water box is arranged on the base body in a drawer-pulling manner.

[0160] Specifically, when the current humidity in the cooking cavity 131 is greater than the humidity preset value in the current cooking mode, it indicates that the humidity in the cooking cavity 131 is too high and the humidity in the cooking cavity 131 needs to be reduced. Based on this, the control device controls the intake fan 31 of the intake assembly 30, the heating element of the hot air assembly 50, and the heating fan of the hot air assembly 50 to operate, so as to quickly discharge the steam in the cooking cavity 131 and reduce the impact on the cooking quality of the food.

[0161] S50: Based on the current temperature being greater than the temperature preset value, control the heating element to turn off.

[0162] Specifically, during the process of discharging the steam in the cooking cavity 131, both the heating fan and the heating element of the hot air assembly 50 are operating. At this time, the hot air assembly 50 provides a hot air flow in the cooking cavity 131. When the current temperature in the cooking cavity 131 is greater than the temperature preset value, it indicates that the temperature in the cooking cavity 131 is too high and the temperature in the cooking cavity 131 needs to be reduced. Based on this, the control device controls the heating element to turn off and keeps the heating fan running, so as to quickly discharge the steam in the cooking cavity 131 while making the temperature in the cooking cavity 131 meet the cooking requirements and reducing the impact on the cooking quality of the food.
